Definitions

  • planks comprising a front axle and a rear axle each carrying two free rotating rollers, and more generally to all planks provided with at least one axle provided with 'at least one roulette.
  • the board brake device in order to be usable in practice, the board brake device must be able to fulfill its function regardless of the position occupied by this board with respect to the ground, whether it is parallel or approximately parallel to the ground, or that it occupies any other position.
  • the field of application of the brake device according to the invention is not limited to skateboards.
  • Such a device can, in fact, be mounted on all objects used in particular for leisure purposes and provided with axle (s) and caster (s) of the type mounted on the boards, for example on multi-purpose sleds which have appeared recently. on the market.
  • the brake device according to the invention described below is mounted, by way of example, on a standard skateboard comprising a front axle and a rear axle, each of which is fitted with two free rotating rollers.
  • this device comprises three assemblies: a braking assembly preferably arranged at the rear of the rear axle and being able to accompany the movements of the latter, an actuation assembly of this braking assembly, and a connecting assembly of the two aforementioned assemblies.
  • a braking assembly preferably arranged at the rear of the rear axle and being able to accompany the movements of the latter
  • an actuation assembly of this braking assembly preferably arranged at the rear of the rear axle and being able to accompany the movements of the latter
  • a connecting assembly of the two aforementioned assemblies are advantageously arranged under the board, with the exception of an actuating member emerging or / and projecting from the surface of the board.
  • FIGS. 1 and 2 represent the device according to a first embodiment.
  • the device is arranged under the board 5, in a zone extending between the rear axle 6 and the rear end 15 thereof.
  • the braking assembly 1 which has a plane of symmetry of trace 25 (FIG. 3) merged with the longitudinal plane of symmetry of the board 5, comprises a support plate 17, two fixed arms 18.18 ′ arranged symmetrically with respect to at plane 25 and connecting the plate 17 by its lateral faces (not referenced) to the axle 6, and two symmetrical braking elements 23,24, fixed to the plate 17 by fixing means 26,27.
  • the braking elements and their support form the braking block.
  • the brake support plate 17 has the shape of an inverted U whose horizontal connecting bar, substantially longer than the two parallel branches, has in its middle a solid handle 22 directed upwards and provided with a central bore 21 of approximately frustoconical profile ( Figures 2 and 3).
  • the plate 17 is connected to the axle 6 by means of arms 18, 18 ′, on either side of the axis of symmetry 25.
  • the lower part of each of these arm has an axis (not referenced) with a threaded end passing through a radial bore arranged in the axle 6, so that the arm is inclined towards the rear by an angle whose value relative to the vertical axis 12 is as a function of the construction characteristics of the axle support 7 and of the assembly 1. In the example described, this angle is approximately 45 °.
  • the arm is fixed to the axle for example by means of a washer-nut assembly, also not referenced.
  • a washer-nut assembly also not referenced.
  • the axis 19 may consist, for example, either of a rod with threaded ends passing right through the support plate 17 and the two arms 18, 18 ′, or of two studs screwed into the plate 17 and arranged one on the left, the other on the right, the axes of these studs having the same support merging with the axis 19.
  • each of the brakes closest to the plane 25 ie approximately the inner half-part
  • This part largely corresponds, as to its shape, to that of the plate 17: it covers the vertical branch and partially the horizontal branch of the inverted U.
  • a bar 29 which extends outwards perpendicularly to the plane 25, preferably extending to the outside line of the tread of the corresponding wheel 16. It is more advantageous that the lower edge of the bar 29 is disposed approximately at the height of the horizontal axis of the caster 16 or at a short distance above or below this axis.
  • At least the entire face of the bar 29 placed opposite the rolling field of the caster 16 may be a curved surface 28, the radius of curvature preferably being equal to the outside radius of the caster.
  • the curvatures 28 are formed so that, when the brake device is actuated, their entire surface comes at the same time to press against the rolling surface of the respective wheel 16.
  • the left and right brakes are preferably made of a synthetic material.
  • the surface 28 can be coated with a lining with a high coefficient of friction replaceable after wear.
  • the arms 18.18 ′ will preferably be made of metal, the support plate 17 made of metal or hard plastic.
  • the braking is thus exerted in a uniform manner on the rollers, since the surfaces 28, where appropriate provided with linings, can thus accompany the movements of the axle at the end of which the casters are mounted.
  • the axle carrying the rollers and, correspondingly, the board itself have a certain aptitude for movement.
  • the rear axle 6 (and similarly the front axle not shown) is connected to a support 7 via, on the one hand, an arm bent with axes 11 and 12 and, on the other hand, of a silentbloc arm 10 itself connected to the support by a silentbloc 8.
  • the support 7 is fixed to the underside 4 of the board 5.
  • the axis 12 In the normal unsolicited position of the board , the axis 12 is vertical or approximately so (depending on the different constructions) and located in the plane 25. Under the effect of stresses printed on the board by the user, or under the effect of obstacles or more generally of the relief of the ground on the rollers, the axis arm 12 can deviate to the left and to the right around the axis of rotation 11, the axis 12 thus constituting the generator of a right cone with vertex "S "and axis 11. The axis of axle 6, perpendicular to axis 12 and orthogonal to axis 11, thus moves in the bottom plane e of the cone and whose trace is referenced 13 ( Figure 2). This movement of small amplitude is of course very limited by the silentbloc arm 10.
  • the actuation assembly 2 comprises a caliper 34, a support plate 40, an actuation lever 42 and a brake pedal 45,46 ( Figures 1 and 2).
  • the stirrup 34 is a symmetrical piece (whose plane of symmetry merges with the plane (25) consisting of a base 35, two wings 37, 38 arranged perpendicularly downward, on either side of the plane of symmetry, and spaced from each other, so as to allow passage to the lever 42. These wings also have in their lower zone a bore 44 of common axis
  • the front part of the base 35 has a clearance 36, also for the passage of the front part of the lever 42.
  • the stirrup is preferably housed in the protective shoe 14 and fixed to the board 5 by the same fixing means 41 as those used for fixing the shoe. the latter has a clearance 49 to allow movement of the lever 42.
  • the lever 42 has at the front a curved portion 48, the end of which is provided with a notch 43 allowing the passage of a cable 30.
  • a bore 44 ′ similar to those 44 arranged in the wings 37, 38, through which the bores pass a rod 39 around which the lever 42 is articulated.
  • the brake pedal 46 is mounted on the base itself by fixing means 47. All the constituent elements of the actuating assembly can of course be made of synthetic material.
  • connection assembly 3 of the braking block 1 and of the actuation assembly 2 comprises the cable 30, the front end of which passes through a ball 33 housed in the frustoconical bore 21 of the plate 17 and ends in a stop bulge 32.
  • the opposite end of the cable passes through the slot 43 of the lever 42 and is fixed there by known means not referenced.
  • An elastic member 31, advantageously a coil spring surrounds the cable 30 between the support plate 40 and the plate 17, and exerts its force on these two elements, so that the lever 42 is maintained in the inactive position shown at FIG. 2.
