Definitions
- Rolling apparatus for roller skate users
- the present invention consists of an apparatus improving in many respects the use and possibilities of roller skates, compared to the use which is currently made of it. It is therefore intended to be used only in combination with roller skates.
- roller skating It also aims to secure the practice of roller skating, in particular by offering greater braking than that of a conventional cycle, such as a bicycle for example, and by making available to the skater other safety devices, which interests all skaters. It also aims to solve other problems related to roller skating, such as learning and carrying, which interests not only all skaters, but also those who are not yet and who can thus easily and carefully to become. Finally, it makes it possible to increase the employment possibilities where the roller skate is little used, in particular in the field of traffic on the public highway, means of locomotion and transport of objects or loads.
- the principle of the present invention is completely different and uses other techniques. First of all, it uses a wheel with a markedly larger diameter and not a simple caster, because the wheel requires to meet the desired goals a certain inertia and a strong grip which is deprived of a rigid caster of low weight and diameter.
- This wheel is intended to roll constantly in front of the skater, in the axis of its path, and to remain in permanent contact with the ground. It is held and controlled by the skater in front of him by means of his two hands via handles or a handlebar, located at the other end of the apparatus, not just one in the middle of the arm.
- the two handles are not intended, as is always the case on cycles of at least two wheels, the unicycles being deprived, to ensure the rotation of the wheel to control the direction and to offer support resistant to hands and arms.
- the hands are not supported on the handlebars but support it, and the steering function is only incidental since it can be obtained by the legs.
- the handles are essentially useful for balance, keeping the arms in a good position of balance and for avoiding uncontrolled movements causing them imbalances or aggravating them, and for assistance in the advancement by traction of the arms.
- the principle of equilibrium with the apparatus of the present application is due to defusing imbalances and not only to impede the fall.
- An imbalance on roller skates can be oriented forward, backward, laterally, or in rotation of the shoulders.
- the front and rear imbalances are due to excessive support on the front or rear wheels respectively, due to a displacement of the center of gravity beyond the support area determined by the extreme rollers. II follows a violent acceleration that the beginner does not manage to master, due to lack of lack of experience of the time necessary to do so. This is how he falls before having had time to restore the position of his center of gravity.
- the imbalance is most often caused or amplified by a bad position of the arms which move the center of gravity to a point located outside the support zone of the extreme rollers.
- the two symmetrical handles of the French device first have the role of positioning the hands and consequently the skater's arms symmetrically and balanced at a desirable height for a good position of the center of gravity, and to maintain this position even in the event of imbalance, so as not to amplify it by an inappropriate, uncontrolled movement , or even untimely arms which play a major role in the position of the center of gravity due to their large and very mobile mass.
- the American patent neither imposes an adequate and symmetrical position of the arms, nor does it prevent their untimely movements, even for the arm fixed to the device, since the caster is not intended to roll on the ground permanently and that it can be easily lifted from the ground in a movement of rear imbalance in particular.
- the American apparatus does not seem to provide either a solution to the rotating imbalances or certain lateral imbalances. It cannot in fact be of limited interest and only for forward imbalances.
- the inertia of the wheel permanently placed on the ground obtained by its weight and / or its dimensions, and / or the distribution of its mass, or the load it supports, instantly opposes the abrupt acceleration mentioned above which is then slowed down, thus offering an additional fraction of a second to the skater's brain to correct the imbalance himself , aided in this by a certain constancy in the arrangement of the masses of the body, the arms remaining in a substantially identical position due to the handles.
- the device even without any braking system, reacts against: on the one hand imbalances in front and back:
- the inertia of the wheel in fact acts in the longitudinal axis as does the pendulum of a tightrope walker laterally.
- the imbalance being fully managed and restored by the skater's brain, without having to use a rigid support as in the American patent, the recovery method is memorized for the future and quickly the reflex times decrease . So that at short notice, having acquired the right gestures and reflexes without having had to undergo the falls, the skater becomes able to manage effectively the same imbalances without the assistance of the apparatus, as does an experienced skater commonly.
- the wheel opposes its resistance to lateral skid because it is connected to the skater by its two arms, and thus it opposes an involuntary rotation of the shoulders.
- the diameter and the tread of the wheel of the invention are decisive both to give the required inertia and grip as well as to provide the good rolling necessary for improvement. performance, the device is not reduced to the simple and only learning to practice roller skating.
- the interest is not in particular to improve the propulsion nor the speed of the skater, but to allow him to roll in a seated position on a seat fixed on an arm comprising a wheel held by a fork at one end, and at the another a handlebar provided with two coaxial handles, one of them being equipped with a lever controlling a brake placed on the wheel.
- Two curved plates integral with the arm allow support on the thighs of the skater when he takes place on the seat.
- Figure 2 of this patent shows in three stages how the skater takes place on the apparatus.
- the apparatus is placed in front of the skater as is usually the apparatus of the present patent application, but not for the same reasons, nor the same use, nor the same results since the German apparatus is mainly intended to operate under and between the legs of the skater, the wheel being behind him.
- the German device which is moreover anteriorized by patent US4386794, requires neither adhesion nor inertia to achieve the desired goal. Neither is described in the cited patents. Even placed in front of the skater to serve as a simple support, it does not need inertia or grip for this.
- the apparatus does not moreover include means for increasing the inertia and the grip of the wheel when it is used in front of the skater.
- the wheel appears with a hub of a large diameter, fine and few spokes, and a thin rim. Its mass does not seem not only not important, but rather concentrated towards the hub, which contributes to a weak moment of inertia.
- the elements that make it up are arranged far enough from the vertical line of the wheel, so that the mass of the lower third of this device is relatively small. relative to its total mass.
- the strictly coaxial arrangement of the handles oriented perpendicular to the arm which has no other purpose than to support the hands or to orient the wheel when it is in front of the skater , is not suitable for obtaining the objectives achieved by this application.
- This arrangement is not ergonomic for performing the movements of the hands, wrists and arms that the use of the present invention requires, and would hinder the effectiveness of these movements while causing discomfort and excessive fatigue for the skater.
- the device described does not have the function of propelling the skater, nor does it describe means for doing so.
- this device is provided with two wheels and two successive axes, parallel and non-coaxial, while the present invention requires at least only one wheel and one axis to operate.
- this device cannot be used without a motor or without electrical energy and cannot meet the objectives of the present invention.
- It is in the form of a rolling device for roller skate users, intended to be used in combination with roller skates of the “quad” type with pairs of parallel wheels or of the “in-line” type with aligned wheels in particular. .
- it is of the type consisting of a device comprising at the top and rear end two handles preferably oriented substantially transversely to the longitudinal axis of the apparatus, each intended to be held simultaneously and freely in front of the skater.
- the handles are capable of directly orienting the link arm in all directions, including simultaneously rotating and pivoting.
- the apparatus is driven exclusively directly or indirectly by the energy coming from the muscular force of the skater, even if this energy has caused the subject to storage.
- the axis of the wheel and the wheel are unique for less weight and better maneuverability. But it is achievable in particular with two wheels, placed side by side, close to or spaced on the same axis or on coaxial axes considered to be the same axis.
- the axis or axes are substantially oriented perpendicular to the link arm.
- the means making it possible to improve the grip of the wheel are for example constituted by the use of a tire, of a tread composed of gripping material such as rubber and / or substantially smooth and / or comprising sculptures lineage and / or relatively wide, by sanding or brushing the surface of the tread, by increasing the pressure of the wheel (s) on the ground, for example by making them bear at least one additional load adding to the self-weight of the device, arranged on the device preferably near its wheel and more particularly of its axis, or resulting from an air pressure.
- these different means can be used cumulatively to obtain the best possible adhesion.
- the diameter of the wheel is between 20 and 45 cm and that of the tread, the profile of which is preferably rounded, is between 3 and 5 cm to provide good grip, not to get stuck in the grooves and roughness. of the road and present a certain inertia. But relatively satisfactory results, even if they are partial, can be obtained without respecting these characteristics.
- the wheel hub through which the wheel axle passes can be connected to the rim in particular by spokes, bars or sticks, or a solid disc.
- the skater holds it in front of him by controlling the trajectory and the inclination of the wheel circulating in contact with the ground in the axis of its path about 60 to 120 cm in front of his skates (depending on the size of the skater), one hand holding each handle.
- the handles are generally held at a height around that of the hips or pubis. The hands firmly grip the handles, but without tension and with a certain flexibility of the wrists.
- the arms are folded and held close to the body, the elbows not deviating from it as on the handlebars of a bicycle, so that its bulk is reduced to a minimum.
- the device In the current operating position, the device is oriented so that the angle formed with the ground by a line passing through both the axis of the wheel and the axis of the handles has a value of approximately 43 ° (+ or - 10 °).
- This angle and its tolerance determine a tilt range of the device where it gives the best results overall in different functions.
- results which may be less, partial or incomplete are however obtained above or below these values. They are therefore not absolute, especially since they vary according to parameters influencing the grip of the wheel such as the condition and nature of the soil, the moisture content of its surface and the load supported by the wheel axle.
- the skater is frequently required to modify this angle for short periods, but significantly.
- the device cannot be confused with a unicycle of which it has neither the saddle nor the pedals, while it has two connected handles and / or a handlebar, which is not the case with a unicycle.
- the arm connecting the handlebars to the fork is much longer and less rigid than on a unicycle, not having to undergo the same loads, forces and constraints.
- its use is very different, the user does not take place on the device.
- the additional load must be placed as close as possible to the vertical alignment of the wheel axle so that its mass offers the maximum pressure to the wheel on the ground. Used in this way, the device undergoes significant forces, especially in torsion, whether at the handlebars, the fork, and especially the link arm. It must be very solid and resistant, especially in torsion, especially since it is difficult to offer it in one piece.
- the link arm comprises folding means lockable, such as telescopic and / or articulated elements, so on the one hand to reduce the size of the device when not in use and on the other hand to adjust the length of said link arm as a function of the size of the skater and in that with regard to the fork, the link arm, and the handlebars, at least two of these elements are separable and assembled together by means of a built-in positive locking means which can be locked and unlocked without offering no degree of freedom in the locked position during use of the device in normal operation, in particular in rotation along the axis of the link.
- folding means lockable such as telescopic and / or articulated elements
- the outside diameter of the wheel offering good performance without too much space for a device intended for an adult is between 35 and 45 cm.
- the effective diameter is between 25 and 35 cm.
- a current brake of a cycle wheel with friction pads is clearly less effective, with identical force, than on a wheel of larger diameter commonly mounted on adult cycles.
- the braking means comprise at least two braking devices each acting on at least one common or different wheel, controlled jointly or distinctly by means such as at least one lever located at a handle, so as to significantly increase the power and progressiveness of braking while ensuring safety in the event of failure of one of them.
- braking devices can be actuated either alternately or simultaneously, alternately then simultaneously or vice versa.
- This double braking device not only has the objective or effect of loading the wheel axle, but also of securing the skater and the apparatus in the event of a failure of a braking device, of increasing the braking power, to offer a different progressiveness and / or power for each of the braking devices, to offer greater progressiveness by an alternative then simultaneous use, to shorten the reaction time when the devices are subjected to the harmful action of rain, to facilitate the use of controls for both right-handers and for left-handers, and to enable the device to comply with the French Highway Code imposing in its article R315-3 on cycles, number of which count the skater using the apparatus, to be provided with two effective braking devices.
- the two braking devices are of the same type and are arranged either on either side of the arms of the fork, or according to different lengths of radius on the rim of the wheel so as to provide by this simple arrangement action and progressiveness different from each other.
- the braking member placed in front of the fork is disposed in the immediate vicinity of the latter, while that arranged in the rear can be moved away from it, its position in this regard depending on the length of the friction pads. , so that the front shoes and the rear shoes do not touch so as not to interfere or interfere.
- This particular arrangement has the particular advantage of freeing up space above the wheel so as to have greater loads there.
- the front brake is arranged as low as possible, while the brake behind the fork is arranged as high as possible.
- This arrangement also makes it possible to obtain a different progressiveness on the two brakes, the lever arm which they exert on the friction pads having a different length and therefore a different effect.
- Such damping elements are only intended to improve handling and cannot have the effect of improving user comfort as is the case on other vehicles.
- the handles are arranged oriented in a plane substantially parallel to the path or transverse to the axis of the wheel, their free end must be inclined downward to suit the ergonomics of the hand and the wrist. But during the use of the device, the skater is frequently required to frequently vary the height of the grips, certainly for a short time, but with a fairly large variation in amplitude. So that this arrangement of the handles is not suitable, because it requires a significant variation in the downward inclination depending on the height where they are held, at the risk of failing to be very uncomfortable.
- the handles are mounted in a plane substantially parallel to that of the wheel axis, transverse to the axis of the path in that it offers more tolerance in outfits at different heights, without create major ergonomic constraints for the hands, arms and wrists. It also and above all makes it possible to better control the inclination of the wheel and to exert with more power a couple of forces on the handles to obtain assistance with advancement.
- each handle is mounted on the device in an orientation substantially identical to that of the axis of a piece of tube held freely and gripped by the corresponding hand while it is located in front at the level of the pubis and hips about 10-15 cm from the body, the unfolded wrist being a natural extension of the forearm, the arms being bent and the elbows held laterally close to the body, the device being in the operating position oriented so that the angle formed with the ground by a line passing both through the axis of the wheel and through the axis of the handles has a value of approximately 43 ° (+ or - 10 °). This angle and its tolerance determine a tilt range of the device where it gives the best results overall in different functions.
- the elbows remain close to the body in a natural space-saving position, and the grip of the handle is ergonomic for the hand which encloses it, so that the latter exerts around a regular support. without undergoing greater and uncomfortable pressure, especially at the base of the thumb, or forcing the elbows to move away from the body.
- the orientation of the handles of a bicycle handlebar is different, because the position of the body seated and tilted forward is not the same, and the height of the hands as the position of the arms are also different, the elbows being often pushed away from the body to have more force both in controlling the handlebars and in pedaling.
- the handles are pivotally mounted on their longitudinal axis according to at least a fraction of a turn, in a free manner or associated with elastic return, friction or locking means, so as to allow the skater by rotary and successive movements of the wrists exerted on the handles themselves to provide forward impulses to the device, which associated with the inertia effect specific to the device provide phases of acceleration by traction towards the 'before produced in a separate and complementary manner to the propulsion obtained by the movement of the legs on the skates.
- the apparatus comprises means making it possible to have at least one load either of ballasting or of transporting, the mass of which is mainly supported by the wheel axis, for example near or on either side of the vertical alignment of the wheel axis, in a substantially balanced manner, these means being for example constituted by a load carrier formed by a trunk, locker or grid, at least one hook, ring or orifice, threaded or not, constituting load carriers, or threaded end pieces making it possible to screw ballast masses coaxial to the wheel at the ends of its axis.
- the means making it possible to receive at least one load close to the vertical line of the wheel axle are mounted on the device so as to have the center of gravity of the load in front of the vertical line of the wheel axis, preferably in a variable and adjustable manner, so as to bring the center of gravity of the device closer to the axis of the wheel by making at least partially counterweight of the elements located between the skater and the axis of the wheel, link arm and handlebars in particular, so that at least part of the mass of these elements and of the load is supported by the axis of the wheel so increase its grip while also relieving the skater's arms.
- the center of gravity of the load can thus be placed more or less in front of the vertical alignment of the axis as a function of its mass and that of the link arm and the handlebar.
- the means making it possible to support an additional load on the wheel axle comprise means for damping and / or absorbing shocks and vibrations caused either by the relief of the ground either by the movements back and forth, so that the load is only subjected to them at most attenuated, such as for example the use in the structure of the load carrier of a material having a certain elasticity, of steel for example, and / or at least one more or less pronounced curvature, and / or a cantilevered position relative to a point of attachment to the device obtained for example by a fixing provided by at most two opposite coaxial attachment points each provided with means effectively opposing the rotation of the load carrier around these attachment points, making it possible to accentuate, during front and rear movements of the arms or rotary movements of the wrists of the propelling effect by an expansion effect of the damping element associated with the inertia of the load.
- the means allowing an additional load to be supported on the wheel axis include means making the load movable along the front axis rear of movement of the device, freely according to the movements printed by the skater at the handles, such as for example the mounting of the load on at least one slide or at least one articulated or elastic arm and preferably associated with means of front and rear end-of-travel damping.
- the load can be constituted by the mass of transported objects or by a ballast mass.
- the load can also be made movable from front to back and vice versa in an adjustable, controlled and lockable manner to adjust the center of gravity of the load relative to the axis of the wheel or to distribute the masses on either side of the wheel axle, either automatically by an appropriate device, or at the discretion of the skater.
- These means can be composed of an electric motor actuated by control means arranged near at least one handle, driving forward or backward by means of an endless screw, for example the load carrier mounted on slides. .
- the load carrier can also be mounted on at least one lockable slide and can be moved manually forwards or backwards after unlocking.
- These adjustable, controllable and lockable displacement means make it possible in particular to adjust the position of the center of gravity of the load relative to the axis of the wheel or wheels, to balance it on either side or partially compensate by effect counterweight the mass of the link arm and the handlebars, as well as the various elements or accessories which they support, so as to reduce the weight supported by the skater's arms to the minimum necessary to ensure easy control of the balanced load on the wheel or wheels, regardless of its weight.
- the apparatus includes means for adjusting the inclination from front to rear and vice versa, either from the loads with respect to the link arm, or the link arm with respect to the load carrier.
- the fixing of loads or accessories on the load carrier is simple and rapid, it is provided with vertical retaining means lockable by a simple pressure on the load to secure it to the load carrier, and unlockable by means control to separate the load, lever for example, associated with lateral and longitudinal load retention means.
- These means consist for example of at least one hook or at least one rod movable about an axis or fixed, provided with return means in the locked position, a spring for example, the pivoting of which is controlled by means which can be actuated by the hand, lever, handle or lever for example, to unlock it while placing it in the waiting position by means of arming the locking device.
- the load or the object to be fixed is in turn secured to complementary means, at least one rod or at least one hook, respectively fixed or mobile intended to take place in the hook or to block the rod of the load carrier, after that 'manual pressure causes it to act on the locking arming means which thus release the hook or the rod which holds the rod or the complementary hook captive in the locking position under the action of the return means.
- the load or the object to be fixed are also provided with lateral guide and support means cooperating with the load carrier on which they rest, to ensure lateral support of the load.

- the appliance and / or the child seat and / or the load carrier comprise lateral stabilization means coming into contact with the ground when the inclination of the loaded wheel reaches a level difficult to control by means of the handles.
- these stabilization means being provided at the point of contact with the ground with rolling or sliding means to soften the contact with the ground when the device rolls, for example a caster swivel mounted to take all directions, or oriented so as to roll when in contact with the ground, or a deflector whose upper part is curved like the tip of a ski to promote its sliding on the ground without risk of hanging it.
- the stabilization means are preferably provided with means for adjusting in length, in height and / or in inclination to determine their intervention threshold, in particular as a function of the nature and / or of the weight of the load, and of the muscular strength of the skater, and folding means when not in use, for example by pivoting towards the wheel, possibly with locking and unlocking means.
- the structure of the seat, and in particular the lateral extensions in which the child's legs take place, can constitute these stabilizers or participate in their implementation.
- the seat, its support or the load carrier is provided with adjustable means making it possible to vary the inclination forwards or backwards.
- the load carrier may or may not consist directly of a basket, a rack or a chest comprising folding means on itself so as to reduce the height, preferably quickly, so as to allow the provision of loads freely inside when it is in the unfolded position, or outside by arranging them and fixing them directly when it is in the folded position , especially when their dimensions exceed its own, the folded position when not in use also significantly improving the size and the coefficient of penetration into the air of the device.
- this basket or rack is made of synthetic material and includes means making it possible to keep the folded parts together so that they do not collide while rolling. These means can consist of deformable elastic hooks, preferably metallic to remain solid and discreet by a small diameter. The curved end of the lever making it possible to unlock the means for vertically retaining the load on the load carrier can also play this role thanks to its elastic return.
- the locker or basket may be fitted with a flexible or rigid cover which preferably opens forward to be actuated when the appliance is parked on its crutches, or still a net preferably slightly elastic and extensible to conform to the shape of the objects when they protrude above the opening of the basket or the rack.
- the device cannot be mistaken or treated as a wheelbarrow.
- the wheelbarrow which is intended for use at low speed, while walking, is not fitted with a braking device.
- it is pulled or pushed, but it is not intended to propel, especially on flat ground or uphill.
- Its handles are oriented in the same axis as the path and are inclined at rest horizontally or upwards in operation to be held in palm hands towards the legs and arms stretched laterally along the legs, while those of the device are worn forward, arms folded, which implies a different orientation and inclination.
- the apparatus is also provided with means for locking or blocking at least one braking member in the working position to immobilize the wheel during parking, so that it can be pressed upright or inclined against any support, and in that these locking or blocking means are provided with an elastic return means in the rest position, for example a hook pivotally mounted at the free end of a handle retaining a brake control lever pulled towards the handle in working position, provided with a spring releasing the hook handle as soon as it is pulled again enough for the hook to be released.
- these locking or blocking means consist of a metal or plastic wire bent to the shape of the brake lever and forming a closed hook, the ends of which are folded towards each other and are introduced into an orifice made opposite at the end of at least one handle, provided on one side with the articulation of a spring of which one branch is supported against one arm of the hook while the other is introduced into a small hole in the end of the handle.
- the hook can be tilted under the handle with the little finger until it is positioned under the lever, which can then be released by hand to find retained by the hook.
- the device can also be parked more conveniently and quickly anywhere, even without any support.
- the device comprises means making it possible to park it in a substantially vertical position while keeping the wheel on the ground, for example at least one crutch formed from a rod or a tube whose free end (s) bear on the ground.
- the device when the device is tilted forward, forming at least two support points with the ground arranged triangularly with that of contact of the wheel with the ground, these crutches being optionally connected together by means, such as a bar or a tube, making it possible both to stiffen them, to act as a bumper, in particular to protect the legs of a young child seated in a seat above the wheel, and to support at least one accessory driving or safety such as a headlight or front light.
- This parking mode is very quick and simple to implement without requiring any particular manipulation.
- the crutch means can also be placed at the rear of the wheel, fixed to the link arm. But preferably, these means are arranged above and in front of the wheel. Advantageously, they extend the means enabling a load to be placed near the wheel, in particular a load carrier. In this way, they can benefit from the shock absorption effect with which these means can be provided.
- the apparatus also comprises retractable means allowing the skater to sit on it or to lean on it when they are deployed, in particular when the apparatus is parked in a substantially vertical position, so as to rest.
- the apparatus is easily removable, and the link arm is telescopic, both to be adjusted to the size of the skater, and to reduce bulk when the apparatus is folded or disassembled.
- the braking transmission means connecting the handlebars to the wheel provided by conventional sheaths for example undoubtedly constitute discomfort and a space requirement during disassembly, or when the link arm is greatly shortened for a small skater.
- the braking command is at least partially transmitted by flexible and retractable type transmission means allowing their size to be reduced when the device is "folded” by retracting the length of its link arm, and / or an adjustment of their length as a function of that of the link arm, and / or an adjustment of the length of the telescopic link arm to a predefined length during its deployment, such that a strong chain preferably passing inside the link arm, the number of links used predetermines the length of the link arm to deploy.
- the load is fixed to the device by means of at least one deformable elastic fixing preformed to the shape of the support and integral with the load, engaged on the support by manual pressure causing its deformation followed by an elastic return substantially to its original shape after its engagement on the support, such as a clip enclosing a tube, that of the handlebars, of the link arm or of the fork for example.

- the goal is not necessarily to store a significant amount of energy to make the car and autonomous, but to constitute a temporary buffer to help the skater a little on the next climb using the recovered energy during the last stop or slowdown, rather than letting it get lost.
- the device further comprises at least one wheel propulsion member itself constituting a ballasting means capable of increasing the inertia and the grip, and control means intended to be actuated by at least one hand of the skater, consisting of autonomous motorized means, for example located in the wheel hub, driven by an independent energy source of the fuel type in a tank, or of the electricity type contained in a battery, said means of storage being arranged either near the wheel or in a substantially balanced manner relative to the vertical alignment of the wheel axle so that most of their weight is supported by the wheel axle, for example against the outside or inside at least one of the arms of the fork, or preferably in an adjustable manner from front to back in front of the vertical alignment of the wheel axle, for example between the stands.

- energy which may or may not be arranged in an adjustable manner in front of the vertical alignment of the wheel axis, in particular so as to increase the pressure of the wheel on the ground and thus its adhesion which is particularly necessary in the propulsion mode.
- the device comprises means for clutching and / or varying the transmission ratio between the wheel and the braking member and / or the propelling member, such as for example a rotary roller, coming into friction against the wheel or a disc integral with the latter, displaceable on slides to vary the length of the radius of rotation of the wheel relative to the roller.
- the disc unites the axis of the wheel with the rim, instead of the traditional spokes
- This variation can be obtained by a lever located on the handlebar or the handle, exerting a traction on a cable when it is pulled by the hand of the skater towards the handle, having the effect initially of bringing in contact until a pre-adjustable stopper a roller integral with and mounted at the free end of the rotor of a reversible electric generator, at a pressure preset by the position of the stopper, with a disc secured to the rim of the wheel preferably having a surface able to increase the coefficient of friction, raised ridges converging towards the axis of the wheel for example.
- the roller is provided with means for increasing its coefficient of friction such as a tread consisting of a coating of gripped or non-ribbed gripping material, rubber for example.
- the traction continued on the lever moves linearly over a few centimeters along the link arm or one of the arms of the fork, the body of the electric generator fixed to a mobile support in a fixed guide rail and secured to the link arm or to one of the arms of the fork, depending on the intensity of the traction exerted on the lever.
- This movement takes place towards the outer edge of the disc while keeping the axis of the roller perpendicular to this edge and oriented towards the axis of the wheel.
- the braking power is increased by reducing the torque of the wheel in return for the increase in the electromagnetic resistance of the electric generator, contributing to a greater production of electric current and resulting from the acceleration of the rotation of the rotor.

- the offset of the device is obtained by the use of a rod fixed by a joint to at least one of the arms of the fork, or to the link arm.
- this rod is articulated on its support so as to fall back towards the device to absorb the shock in the event of a collision with a foreign body or when it is not used, to reduce the size.
- the conjunction of a visual security function with a rear view mirror is justified by the fact that the two must be offset to the outside so as not to be masked by the skater's body, in particular with regard to the red light which must be visible from the rear. Preferably if only one is installed, it is on the traffic side.
- the device can be equipped with safety devices and assistance with driving, and in particular with information means, visual and auditory signaling and safety, both for other users and for the skater, who can use the electrical energy recovered and stored during braking, such as a lighting projector, a fixed or flashing light device, a surface that attracts visual attention in a fluorescent, phosphorescent, reflective, reflective color, an audible, manual, electric, electromechanical or electronic horn, a buzzer using the rotation of the wheel to inform pedestrians of the speed of movement, at least one preferably folding mirror, a speedometer and odometer communicating by waves with an information sensor located at the wheel.

- the counters currently known for roller skates are not satisfactory because the information display often placed on one of the skates is difficult to read and accessible to manipulation during skating.
- the information provided is not reliable since the rollers do not travel exactly the same path as that of the skater because they are not in permanent contact with the ground and they roll obliquely to the path of the skater.
- the counter basing its calculations on the rotation of the wheel of the device therefore eliminates these drawbacks and provides correct information.

- the device has a wheel 3 with a diameter of approximately 40 cm composed of an aluminum alloy rim 10 with three curved branches, and a tire 3 provided with a smooth tread 6 in rubber rolling on the ground 5 around a wheel axle 4 3 mounted on ball bearings.
- the tread was sanded with sandpaper and brushed with a wire brush to increase its grip.
- the wheel 3 is mounted on a fork 7 with two arms fixed to the lower tube of the connecting arm 2 with a connection without degree of freedom, in accordance with that illustrated in FIG. 24.
- the length of the fork 7 is 30 cm and the diameter of his arms 22 mm.
- the arms of the fork 7 have threaded orifices 153 formed in circular parts 154 projecting and welded to the arm of the fork 7 allowing two brake devices 19 with friction pads acting on the rim 10 of the V-brake type to be attached thereto, and accessories (pump, bottle cage, mirror, etc.). ).

- the fork 7, the link arm 2 and the handlebar 8 in particular are made of polished aluminum and treated against oxidation.
- the connecting arm 2 is rectilinear and telescopic comprising two tubes, one of which slides exactly in the other, with the interposition of an intermediate tube made of material facilitating the sliding of the tube of smaller diameter in the other, plastic for example. But for aesthetic considerations, it may have at least one curvature, this however hampering the possibilities of telescoping.
- the lower tube has a diameter of 35 mm and the upper tube of 28 mm. Locking the length of the link arm 2 is also provided by an upper eccentric clamp 11 manually controlled by a lever 12.
- the lower tube has longitudinal slots 102 at each of its ends with a width of approximately 3 mm over a length of 35 mm, so that allow a deformation of the tube under the action of the clamps 11 and 13, and tighten the part inserted therein so that it remains trapped there.
- the slots 102 are at least two in number, but the deformation is easier and more regular if there are three equidistant slots 102, and the part is held better, although the breaking strength is lower. So that these slots 102 do not constitute an initiation of rupture or tearing of the tube, they are finished with a circular cut 103 increasing the opening at the point of embrittlement of the tube caused by the slot 102.

- a fluorescent flag 17 is arranged at the free end of a telescopic element 16 housed when it is folded in the left handle 1, that is to say on the side of vehicle traffic.
- the other end of the tube 131 comprises an articulation 135 of the tube 131 with the arm of the fork 7 in order to fold it up for less bulk when not in use.
- To block the tubes 131 in position of use they comprise locking means 134, for example a pin 134 penetrating horizontally into the arm of the fork 7.
- the child seat 96 is provided with rigid stabilizers 97 which are integral therewith, each provided at their end with a wheel 98 coming to roll against the ground 5 in the event of inclination of the wheel 3 beyond a certain threshold.
- the variation device illustrated in FIG. 23 comprises a reversible electric generator 85 provided with a roller 84 having a tread 6 coated with a ribbed and gripping surface of rubber, mounted integral and in the axis of the rotor centered on the spoke 83 of wheel 3, and disposed in the immediate vicinity but without touching it of a disc 81 integral with axis 4 and rim 10 of wheel 3 and having ridges 80 in relief converging towards axis 4 of wheel 3 in a peripheral zone of the disc 81 intended to come into contact with the roller 84.
- the roller 84 is held in this position by fixing the reversible electric generator 85 at two points 82 secured to a slide sliding in a fixed rail 155 , integral and focused on one of the arms of the fork 7.
- the variation is obtained by actuating a lever 18 fixed to the handlebar 8 facing a handle, exerting traction on a cable 15 having the effect initially of bring the tread 6 of the roller 85 into contact with the disc 81 as far as a pre-adjustable stop, according to a pressure pre-adjusted by the position of the stop, and in a second step by continuing to pull on the lever 18, to move linearly over a few centimeters along the arm of the fork 7 the body of the reversible generator 85 according to the intensity of the traction exerted on the lever 18, in order to move it in the direction of the outer edge of the disc 81 while maintaining the axis of the roller 85 perpendicular to this edge and centered on the radius 83 of the wheel 3, so as to increase on the one hand the braking power by reducing the torque of the wheel 3 in return for the increase in the electromagnetic resistance of the generator electric 85 then producing a greater amount of electric current resulting from the increase in the speed of rotation of the rotor, and on the other hand
- the return to their rest position at the end of braking or of propulsion of the body of the reversible generator 85 towards the axis 4 of the wheel 3 on the one hand, and of the tread of the roller 84 in the immediate vicinity of the disc 81 of on the other hand, is provided for each by elastic return means, a spring for example.
- the head of the fork 7 has a diameter allowing it to be embedded in the lower tube of the link arm 2, the section of which is round. It has at least one longitudinal lug 100 in excess thickness, the free end of which is rounded to facilitate its engagement inside a corresponding notch 99 in the lower tube of the link arm 2 with which it must cooperate for a link devoid of play in rotation, even without tightening a collar, while allowing longitudinal translation.
- the lower tube of the connecting arm 2 is provided with 3 slots 102 having a circular cutout 103 at the bottom to reduce the risk of tearing the metal.
- the droplet section 101 for example, makes it easier to obtain, by its only geometry, a connection with these characteristics.
- Figures 25 to 28 the arrows indicate the direction of the forces exerted by the skater u.
- Figure 25 shows schematically an advancement assistance by movement of the arms b bearing on the wheel 3 by exerting a couple of forces on the handles 1 in the axial plane of the link arm 2, while keeping the wheel 3 substantially perpendicular to the ground 5.
- diagram A when the skater u is propelled on the right skid p for example, its right b arm exerts a forward thrust in the axis of the link arm 2, while the left b arm exerts an equivalent pull in the same axis.
- This couple of forces exerted in the axis of the link arm 2 does not have the effect of modifying the inclination of the wheel 3 or its direction.
- the grip of the wheel 3 therefore plays an essential role here in preventing its lateral displacement in order to give solid support to the arms b of the skater u.
- This movable support in the direction of the path t and laterally resistant allows the pad p which progresses laterally obliquely in the opposite direction to do so with much more efficiency and power. This phenomenon is even more noticeable on climbs where the oblique progression takes place more laterally, with a more open angle with respect to the support, so that it proves to be even more effective.
- the upper body being well supported, it is insensitive to imbalances caused in the climbs by a very lateral step giving little support before rear, and amplified by a low speed reducing inertia and aggravating shocks due to ground irregularities 5.
- This movement essentially uses the ground grip 5 of the wheel 3, but also its gyroscopic effect resulting from its inertia in rotation.
- FIG. 26 shows diagrammatically an aid to advancement by forward and backward movements of the arms b.
- the skater u folds his arms b while keeping the wheel 3 in the axis of its path t and substantially perpendicular to the ground 5 when it carries its weight on a pad p oriented in the axis of the path t.
- diagram D he deploys his arms b in a sudden movement, either until total stretching, or with a lesser amplitude, but in all cases by clearly stopping this movement while staying on the same shoe p similarly oriented to offer the less resistance to advancement, so as to launch the device forward in the axis of the path t with more or less force.
- the inertia of the apparatus pulls the arms b of the skater u forward.
- the grip of the wheel 3 also plays a role because it must not slip during the sudden impulse, nor when it returns to contact with the ground when it left it under the effect of the abrupt restraint at the end of race, because it then transmits in a forward traction the energy accumulated by its inertia during the pulse.
- the skater u folds his arms b again when he puts his weight on the other skate p to renew this propulsion at each step.
- the step is then asymmetrical: By carrying his weight on the leg giving him the best balance, the right for example, the skater u propels himself with the skate p while suddenly deploying his arms b and maintaining this length position, its weight being carried as much as possible on the rear part of the skid p kept oriented in the axis of the path t in order to benefit as much as possible from the momentum given by the inertia of the device and from the propulsion of the skid p ( diagram D).
- FIG. 27 diagrammatically shows an assistance with advancement by movements of the arms b imparting a scull movement to the wheel 3.
- the arms b exert a couple of forces on the handles 1 in the axial plane of the link arm 2, while slightly turning the handlebar 8 in the direct direction so as to orient the wheel 3 towards the ground in the direction of the axis of the path t, while the skater u is resting on the right skate.
- the same sculling movement giving the wheel 3 a helical movement can also be carried out by pressing on the two legs, the skids oriented in the axis of the path t and substantially at the same level, without making any propellant steps (diagram H).
- This is particularly interesting when the track available on the ground 5 does not ensure the pitch of the skater u, between two lines of cars for example. In both cases, this advancement assistance gives a regular and symmetrical movement.
- This sculling movement essentially uses the grip and inertia of the wheel 3.
- the angle formed by the link arm 2 with the ground is large, the flush is reduced and the rotation of the handlebar 8 is more similar to that obtained on a bicycle, resulting in the wheel 3 mainly by its orientation by relative to the axis of the path t, retaining an inclination relative to the ground 5 fairly close to the vertical.
- the turning radius is larger in the first case than in the second, which allows instantaneous obtaining of many possibilities in riding, simply by combining the orientation of the handlebar 8 with the height hands, this significantly modifying the hunting angle.
- the apparatus and skater assembly constituting in a way a three-wheeled vehicle, exhibits extraordinary maneuverability, the steering being provided by the front axle with the arms b or by the rear axles with the legs or in combination with the two, which, added to the instantaneous variation of the hunting angle, offers a multitude of combinations, from the turn obtained by the orientation of the pads without modifying the orientation of the wheel 3, to the U-turn by rotation without turning radius, through the counter-turning of the wheel 3 with respect to the pads p forming a resistant support allowing even at low speed a significant inclination of the skater's body, which gives him particular and new sensations close to those felt in cut corners in skiing or snowboarding.
- Figure 28 shows schematically an assistance to the advancement by movement combining the movements of Figures 25, 26 and 27. While it is in support and propulsion on a skate p, the right for example, the skater u suddenly deploys his arm b and thus launches the device forward, no longer in the axis of its path t, but slightly obliquely to the left (diagram I).
- the user can skate as usual, only with the legs, passively by limiting himself to pushing the device in front of him, as he would do with the device described in German patent DE 10043857.
- the device then constitutes as a stroller a mass to move in front of you, which reduces the speed of movement.
- the skater u develops more power than without, which significantly increases its speed, thanks to increased energy expenditure, both uphill and downhill and on flat ground.
- the general step practiced by the user is specific to the use of the device in dynamic mode, which makes it a sport and a leisure in its own right making the whole body work harmoniously , giving possibilities, results, performances and sensations quite different from those resulting from the traditional practice of roller skating.
- the wheel 3 To fully play its role, the wheel 3 must have a significant moment of inertia. To achieve this, we will tend to increase its weight and diameter. But for practical reasons, the basic device must not reach large dimensions or weight so as to be easily portable or transportable when the wheel 3 is not placed on the ground, for example on stairs. Also the wheel 3 must keep a reasonable diameter and be relatively light by favoring its inertia.
- the effects cannot be obtained validly for external diameters less than 14 cm, and it is necessary to count at least 18 to 20 cm to begin to obtain interesting results. And to achieve much better performance, taking into account in particular the driving constraints, it is desirable to use an outside diameter of around 40 cm for an adult. To achieve this at a significant moment of inertia and for a given weight of the order of 1.5 kg for example, the mass must be arranged as much as possible towards the periphery of the wheel 3. This result can be obtained in particular by using a fairly wide tire and / or with a thick tread, an inner tube, a wide, thick and massive rim at its periphery, few but thick and massive spokes especially towards the periphery, and a weaker hub and light possible.
- the inertia of the wheel 3 and its gyroscopic effect can be further reinforced by the addition of small ballast masses or removable weights placed near its periphery or the tire.
- the mass of the complete wheel 3 must be at least equal to 20% of the total mass of the 'basic device without accessories and ballast masses 151. But it is really a minimum and the rate of 25% gives more noticeable results. A rate of 30% gives satisfactory results and a rate of 35% gives interesting results. They become very attractive from a rate of 40%, but they still improve significantly for higher rates of 45% or even 50%. Around 55 or 60%, the results are excellent.
- the mass of the lower part of the apparatus comprising the elements located therein, in particular at least a part of the wheel 3 and possibly of the load carriers, accessories or ballast masses 151, representing the lower third of the total length of the device held vertically with the link arm 2 fully extended, must be at least 25 % of the total mass of the device possibly fitted with accessories, load carriers or ballast weights 151. But this is really a strict minimum and the rate of 30% seems almost necessary. From a value of 35%, the results are a little better but it does not take less than 40% for them to be satisfactory. For a value of 45%, the results are sufficient, but become practically good at 50% or 55%.
- FIG 32 they are composed of a round tube 162 bent substantially at right angles to the end of the smallest part of which is mounted a wheel 163 fixed by a screw 164, while the greatest length is pivotally mounted inside a tube 159 fixed by two screws 165 screwed into tapped holes 153 formed in supports 154 welded on the outside face of the arms of the fork 7.
- the tube 159 has a slot 160 oblong over about one quarter of the circumference of the tube 159 in which takes place a hexagon socket headless screw (161) screwed and blocked in the tube 162.
- a load 66 consisting of a ballast is held at each of its ends above the wheel 3 by a flexible steel arm 167 extending vertically from the axis 4 of the wheel 3 to which it is fixed by a nut tightening the plate 56 on which the lower end is welded, without the possibility of pivoting due to the locking means 175 enclosing the edges of the flattened end of the fork arm 7 as shown in Figure 11.
- the mass moves from front to back according to a radius equal to the length of the flexible arms 167 while being damped at the front and rear end of travel by the spring effect of the flexible arms 167.
- the load 66 is projected forward, which gives additional traction to the arms b of the skater u when it reaches the front stop.
- the interposition of a stop or a cable 176 connected from the flexible arm 167 to the threaded support 154 makes it possible to improve this traction by neutralizing the front end-of-travel damping produced by the flexibility of the arm 167.
- a load 66 is suspended on each side of the wheel 3 either by a flexible arm fixed to the axis 4 of the wheel 3 and operating in a manner similar to that of FIG. 30, or by a rigid arm 166 articulated on the axis 4 of the wheel 3, preferably provided with end-of-travel damping means constituted by a double spring wound around the axis 4 of the wheel 3.
- These mobile loads are illustrated from the front in the figure 33, in combination with fixed ballast masses 151 comprising a threaded part which is screwed to the end of the axis 4 of the wheel 3. According to a variant, they can be fixed even more quickly with a bayonet connection. Of course, these ballast weights and loads are preferably used alone.
- the moving masses 66 allow faster propulsion.
- Fixed masses 151 are particularly interesting for beginners because they increase inertia without rebound effect or relaxation, and effectively oppose large and repeated imbalances specific to beginners.
- the load 66 is movable on slides 168 provided with damped limit switches 169 and supported by the axis 4 of the wheel 3 by two rigid arms 170 whose rotation around the axis 4 is prevented by a rigid flange 179 fixed by means of screws at one end to one of the arms 170 and by the other to the threaded support 154 secured to the fork arm 7.
- the effects obtained are similar to those of the load 66 of FIG. 30, with, however, the advantage of providing, with equal ballast mass, a rectilinear force of inertia better oriented in the direction of the path t.
- FIG. 36 shows a variant of the invention comprising an axis 4 consisting of two coaxial parts on each of which is mounted a wheel 3 with a diameter of approximately 50 cm, distant from the other by approximately 70 cm.
- the coaxial axes 4 are held by asymmetrical forks 7 with one arm, externally to them.
- the two forks form a lowering cradle with respect to the axis 4 of the wheels 3 the point of assembly with the connecting arm 2.
- This assembly comprises means of articulation around an axis 156 held by two parallel flanges 171 provided lockable adjustment means of the inclination of the link arm 2 coming to take place between them, the unlocking of these adjustment means being preferably actuated by control means arranged near at least one handle 1, to reduce the size of the device when stopped by straightening the link arm 2 substantially vertically with a single gesture.
- the planes containing the wheels 3 are arranged parallel and symmetrically to the plane containing the link arm 2.
- Two slides 172 provided with locking and unlocking control means to which a load 66 can be subjected make it possible to move the load 66 from before back and vice versa to support at the handles 1 only a weight of 1 to 1.5 kg approximately useful for good control of the device.
- the device rocks towards the ground 5 at the rear by letting go of the handles 1 and towards the front if the link arm is straightened forward perpendicularly to the slides 172.
- This configuration of the device according to the he invention allows the transport of heavier and bulkier loads 66 without the need to use stabilizers 97.
- the invention is not limited to the embodiments described here by way of illustrations and examples.
- the elements and means which have been described and illustrated in order to obtain an increase in the inertia of the apparatus and of the wheel, and of the grip of the wheel could be used independently of a device described in claim 1 which n 'would not.
- such means could be adapted to a known device such as for example that of the German patent DE 10043857, which would have the effect of conferring or making it possible to confer on said known device which is currently deprived of the essential features of the present invention.
- the invention is capable of industrial applications in the field of sport, leisure and non-polluting means of transport, both of the individual and utility types.
