- the steering plate (5) is folded once square upwards along its two front and rear edges respectively (5a) and (5b), and twice square upwards, then inwards in (5c) on its inner longitudinal edge if we consider the position of the user's shoe.
- latches (13a) to (13c) comprise, in their part located under the plate (5), orifices for the passage of an elongated plate (14), parallel to said plate (5) and arranged along the longitudinal axis of it.
- the plate (14), folded back at its rear part at (14a) is held by three guide elements, front, central and rear, respectively (15a), (15b) and (15c), which are formed by projections directed towards the bottom, carried by the underside of the plate (5).
- the plate or axis (14) passes through the guide elements, central and rear, respectively (14b) and (14c), and it penetrates, by its front end, into a cavity of the guide element (15a).
- the steering plate (5) is held at the front on the front chassis unit (7) by a pinned pin (17). To this end, the plate (5) has a downward projection (18), and the front chassis block (7), an upward projection (19), the two projections (18) and (19) coming in bearing against each other and being connected by the axis (17) parallel to the longitudinal axis of the roller skate.
- the plate (5) is, in the same way, connected to the casing of the engine block (8).
- a bracket (20) fixed to the latter by a bolt (21) and cooperating with a projection (22) directed downwards, carried by the plate (5), an axis (23 ) connecting the bracket (20) and the projection (22).
- the light (16c) allows the projection (22) to pass through the plate (14).
- the plate (5) is held on the gearbox (9).
- a support plate (24) is fixed by bolts (25) to the rear of said gearbox, and the plate (5) has a downward projection (26) and being connected to the plate -support (24) by an axis (27) locked by a pin.
- a spring (27a) ( Figure 3) forces the plate (5) to return to its central position.
- a protective body (28) is provided, which comprises a central plate (28a), parallel to the plate (14) and disposed below the latter.
- Said plate (28a) is bordered by two inclined longitudinal wings (28b), opening towards the outside, which are extended externally by extensions (28c) overhanging the rollers (3) and (4), and folded down along rounded zones (28d) to form lateral protections (28e), arriving approximately at the level of the hubs of the rollers (3) and (4).
- the plate (28a) comprises, from front to rear, lights respectively (29a), (29b), (29c) and (29d).
- the lights (29a), (29c) and (29d) allow the passage of the three connecting elements of the steering plate (5), respectively to the front chassis unit (7), to the motor housing (8) and to the gearbox (9), as described above.
- the plate (28a) is also fixed to the motor housing (8) by a central bracket (30) bolted to said housing.
- the motor (8) transmits the movement to the gearbox (9) which has a removable wall (9a) to allow access to it if necessary.
- the gearbox (9) is fixed to the motor housing (8) by bolts (31).
- the drive shaft is extended by a primary shaft (32), supported at each end of the box (9) by front and rear bearings, respectively (33) and (34). On the primary shaft (32), freely rotate four pinions (35) to (38), from front to rear.
- a secondary shaft (39) is also arranged in the gearbox (9) parallel to the primary shaft and below it. It is held by bearings (40), (41), at each of its ends, and it receives a set of four pinions respectively (42), (43), (44) and (45), cooperating respectively with the pinions (35), (36), (37) and (38).
- Two control rods respectively (46) and (47) ( Figure 2) actuate synchro rings, respectively (48) and (49), each having three positions and arranged, for the first, between the pinions (35) and ( 36), and, for the second, between the pinions (37) and (38).
- the synchro rings (48) and (49) control jacks respectively (50) and (51) ( Figure 3), also having three positions corresponding to those of the synchro rings.
- the speed change takes place as follows: the ring (48) being in the forward position in the direction of travel, the first gear is engaged and maintained by the jack (50) controlled by the rod (46). In its intermediate position, the jack (50) maintains the neutral position. When the jack (50) is in the second position, the second gear is engaged, the ring (48) having slid on the spline shaft (32) and having made the pinion (36) integral with said shaft (32).
- the cylinder (50) When the cylinder (50) is no longer stressed by the first gear, that is to say that it has returned to mid-point or neutral, the cylinder (51) is no longer self-locked and it allows the passage of the third gear via the control rod (47), sliding on the spline shaft (32), the synchro ring (49) towards the pinion (37), on which it is locked .
- the fourth speed is, in turn, controlled by the jack (51), causing the control rod (47) to slide the synchro ring (49) on said shaft (32) in the direction of the pinion (38), the securely locking on the shaft (32).
- the first execution phase will return to neutral (central point).
- the cylinder (50) is controlled by the switch back to neutral position; only the jack (51) can exercise the advancement of the synchro ring (49) towards the pinion (37) to engage the third speed. It should not be forgotten that the skater has one skate on each foot and only one command in the hand, and when there is a change of speed, the execution will be done on the right skate and the left skate .
- the bevel gearbox (10) is held on the gearbox (9) by bolts not shown, distributed in a circular fashion around the shaft (39) and a centering shoulder (also not shown) holding it in position.
- the secondary shaft (39) enters the bevel gearbox (10) and it carries, at its end, a bevel gear (52) cooperating with a large crown (53) keyed onto a shaft (54).
- the direction of rotation of the shaft (54) can be reversed by the rotation of a half-turn of the box (10) relative to the box (9), and it suffices, for this purpose, to disassemble the bolts fastening, rotate the box (10) by half a turn, then replace the bolts in this position.
- a vertical plate (55) At the rear of the gearbox (10) is fixed by bolts, not shown, a vertical plate (55), the role of which is indicated below.
- the chassis unit (7) is held on the motor housing (8) by bolts (56), regularly distributed over a circle.
- the wall (7a) of the chassis block (7), which is adjacent to the motor housing (8) carries the pivot axis (57) of a steering T (58).
- the upper part (59) of the steering T (58) carries, in a shoulder, at each of its ends, a ball joint (60a) (60b) in alignment with the axis (57) each of the ball joints (60a) (60b ) controlling a rigid link (61a) (61b), passing through the upper wall (7b) of the chassis block (7) and the plate (28a) through the aforementioned opening (29b).
- Each link (61a, 61b) carries, at its end opposite the ball joints respectively (60a, 60b) a housing receiving another ball joint (62a, 62b), whose axes are carried by the steering sole (63.5) and are parallel to the axes of the ball joints (60a) and (60b).
- the steering sole (63) is held on the chassis unit by a pinned pin (63a, 17, 23 ).
- each link (66a), (66b), receives, at the other end, a ball joint respectively (67a) (67b) which is fixed to the hub respectively (68a), (68b) of the front wheels (3).
- the hubs respectively (68a) (68b) carry so-called top ball joints, respectively (69a) (69b) which connect the points of triangular parts (70a), (70b) of elements called upper parallelograms (71a) (71b) ending with two parallel branches extending the triangle and lying in the axis of the latter passing through its apex connected to the ball joint (69a) (69b), these branches being fixed respectively to the front wall (7c) of the front chassis (7) and to an intermediate partition (7d), parallel to the latter ( Figures 1 and 2).
- Each of the two links (77a) (77b) is fixed to an element (71a), (71b), as can be seen in FIG. 4.
- the hubs (68a), (68b) receive the axes (81a), (81b) of the rollers (3), which are supported by bearings (82a), (83a); (82b), (83b). It goes without saying that a seal is produced by seals, which are not shown.
- the axes (81a), (81b) carry the rims respectively (84a), (84b), by a hard and crimped mounting, not shown in the drawing.
- the rims, casters and fixing bolts of the casters are identical for the front wheels (3) and the rear wheels (4). These elements have therefore been designated in the drawing by the same reference numbers.
- the transmission shaft (54) of the bevel gearbox (10) is held by bearings (87a), (87b).
- a double constant velocity universal joint (88) On one side of the output of the shaft (54), is arranged a double constant velocity universal joint (88), the articulation of which, on both sides, is in alignment with the articulation of the suspension .
- a transmission by flexible hose (89) On the other side of the output of the shaft (54), there is a transmission by flexible hose (89), since there is no reverse gear.
- the flexible spring type transmits movement in one direction, according to the invention.
- the pads (1) can be fitted with cardan joints or flexible hoses, as described above.
- the output of these gimbals or hoses is fixed on yokes respectively (90a) (90b), inside which are ball bearings (91a) and (91b), and freewheels (92a) and (92b) , mounted side by side on the axes (93a) and (93b) passing inside the hubs (94a) and (94b) held by bearings (95a) and (95b) and (96a) and (96b).
- the axes (93a), (93b) support rims (84a), (84b) as well as the wheels (85a), (85b) and their bolts (86).
- the undersides of the rims (84a), (84b) of the front and rear wheels can receive brake discs, such as the discs (97a) (97b) shown for the rear casters (4) in FIG. 2.
- Braking can be of the clamping type by "ferrodo" (98), as shown in Figure 2 for the right rear wheel, on either side of the disc (97b), or by pressing on one side, as shown in (99), (100) in Figure 2, for the left rear wheel.
- the rear suspension of the skate (1) is formed by the upper parallelograms (101a), (101b), articulated, on one side, on the gearbox (9) by bolts (102a) and (102b) ( Figure 3 ), and, on the other, on the hubs (84a), (84b) by bolts (103a), (103b).
- the suspension is carried out by jacks (104a), (104b) and damping springs (105a) (105b), the assembly being connected, on the one hand to the parallelograms (101a), (101b) at the points respectively (106a) (106b), and opposite, to the plate (55) by bolts (107a) (107b).
- a stabilizer bar (108), held by two yokes (109a), (109b) is carried by two links respectively (110a) (110b) on the parallelograms (101a) (101b) to allow articulation.
- the lower parallelograms (see Figure 3) designated by the reference numbers (111a), (111b) are different, because it is expected that they can be lengthened or shortened by the provision of threaded bars not to the right and not to left, respectively (112a) (112b).
- the lower parallelograms (111a), (111b) are fixed to the plate (55) by bolts respectively (113a) and (113b) and to the hubs respectively (94a) (94b), by bolts (114a), (114b) .
- a contactor (115) ( Figure 3) controls the position of the ground support to suppress the braking off.
- the rear plate (55) carries a fixed emergency brake shoe (55a) (at 55b) ( Figures 1 and 3).
- a heat engine (116) actuates a power generator (117), regulated at (118), for storage in a power tank (119), part of which the energy comes to the manual control (120).
- This is arranged threaded in the palm of the hand and held on the wrist by a strap (121).
- An order can be made for the right hand or the left hand; the one shown corresponds to the right hand.
- Throttle control is proportional to thumb thrust of the control. Braking is carried out on all of the skate wheels (1) by depressing the control by the four fingers. A set of indicators and control means (pressures, flows, speeds) makes it possible to manage the orders given.
- An electronic or hydraulic regulation (122) manages all orders, protects overvoltages or overpressures, manages the servo motors. Overloads and overpressures are released in (123).
- the regulation (122) also controls the shifting of gears and locks in good time so as not to have two gears at the same time.
- the command gives priority to braking instead of acceleration and it is obtained, if the skater accelerates too quickly, that the engine switches to the safety position. It will then be necessary to start from zero with the acceleration control to resume normal operation.
- FIG. 6 we see that there is shown a ski (300) according to the present invention.
- the elements of the skate (301) which are found identically on the ski (300) have been designated by the same reference numbers as those used to describe the skate (1). These are the motor (8), the gearbox (9) and the angle gearbox (10) with its elements (41); (52-54); (87a) and (87b), as well as (50).
- the track is an assembly articulated on one side, composed of the transmission casing (302) provided with its cover and its screws.
- the transmission casing (302) is held on the angle gearbox (10) by a tubular support (303), itself held by screws not shown.
- the support (303) ensures the articulation of the casing (302) by means of a wear ring (304).
- an identical tubular support (303) is disposed, held by screws not shown, ensuring articulation and rigidity, covered by a wear ring ( 305), cooperating with the bearing end (306) of a guide piece (307).
- the guide (307) comprises a ring (308) for supporting a track housing (309a) with the interposition of a wear ring.
- a bearing (310) is received which maintains an axis (311) supporting and passing through the roller (312) of the track (309), held by two bearings (313) and (314 ) and by a freewheel (315).
- the axis (311) is held by two bearings (316a) and (316b), themselves held inside the transmission housing (302). The latter receives the joint by a ring not shown.
- the transmission takes place from the axis (54) by a pinion or a keyed pulley (317), a chain or a toothed belt (318), to a pinion or a pulley (319) keyed to the shaft (311) , which drives the actual track (320) via the roller (312).
- the two track housings (309a) and (309b) hold the track rollers (321) to (324) of the track (320), the tensioner roller (325), as well as the support support roller (326). caterpillar. All have a long clamping bolt (327) and a bearing tube (328). We could mount two ball bearings on each roller.
- the flexible, rubberized track (320) receives, around its periphery, a set of pads (329) allowing better grip on snow (FIG. 7).
- the pads (329) do not protrude from the underside of the skis (300).
- the shaft (54) rotates in a direction such that the track (320) tends to press on the snow to give better grip. It is assisted in this by four springs (330), (331), (332) and (333), fixed on the track housings (309a). and (309b) by one end, and by the other ends, to bent legs (334) screwed into the ski (301) by screws (335).
- the assembly (8-9-10) is held on the ski (301) by a lug (336), on the engine side (8) (FIG. 8) held thereon by bolts not shown and on the ski (300 ) by screws (337).
- Two other legs (338) ( Figure 7) hold the angle gearbox (10) on the ski (330).
- the track assembly (320) can be raised by slaving and lowered by a simple gesture of the tip of the stick on the lever.
- a part (339) which carries a stud or central axis (340). This receives a ring (341) held by a pin (342) and provided with a "ferrodo" serving as support on the part (339).
- the ring (341) is extended by a lever (343) to which a rod (344) is articulated, the opposite end of which is articulated to a connecting rod (345).
- the latter is pierced with three holes, two to hold two square levers (346), (347), fixed on the one hand to the ski (300) by screws (348) and on the other hand, to pins ( 349) carried by the casing (309a).
- the rod (345) receives the end of a spring (350) connected to the same base (334) as the aforementioned spring (333).
- the track (320) can be locked at the front and at the rear by pawls (351), (352) which hold two tabs (353) (354) welded on the casing (309b) from below.
- the two pawls (351) (352) are kept pressed on the two lugs (353) (354) by springs not shown between the lug under consideration and a cover casing (355) held on the ski (300) by front and rear closures (356).
- the two pawls (351) and (352) are fixed on a axis (357) held by three bearings (358) (two are shown in Figure 6) in the cover housing (355).
- the axis (357) protrudes at (357a) outside the casing (355), where it is folded towards the inside of the ski (300) to allow easy release of the track (320) by pressure on said axis (357).
- a contactor (359) (FIG. 6) controls the correct position and neutralizes the driving effect of the lever (307 ).
- Figures 9 to 11 are views similar to Figures respectively 3, 4 and 2, showing an alternative embodiment which consists of a double track shoe.
- the elements of the skate in FIGS. 2 to 4, which are identical in these last three figures, have been designated by the same reference numbers, and the analogous elements, by reference numbers greater than 300.
- the front axle ( Figure 10) is modified to have a wheelbase identical to the rear axle by upper parallelograms (471a) (471b) with slide to allow the tension of the track.
- These parallelograms (471a) (471b) are held by identical bolts (72a) (72b) on the frame (7c), as well as the lower parallelograms (480a) (480b) which are held by the bolts (81a) (81b ) on said frame (7c).
- Parts (401a) (401b) join the lower and upper parallelograms to the hubs (68a) (68b), these parts being each held on the hubs (68a) (68b) by bolts respectively (402a) (402b).
- the upper and lower parallelograms are fixed to the parts (401a) (401b) by bolts (403a) (403b) which allow the tension of the track.
- the suspension cylinders (74a) (74b) (FIG. 4) are each replaced by a rigid link (474a) (474b) held by the axes of the same type (73a) (73b) on the wheel side, and (75a) (75b) built side (7c). We therefore obtain a rigid assembly.
- the ball joints (60a) and (60b) are mounted in the frame (7c), the two links (61a) (61b) therefore being rigidly blocked.
- the rear axle ( Figure 9) is kept rigid by replacing the damping cylinders (104a-104b); (105a-105b) by rigid rigs (404a) (404b) held by the same bolts (106a) (106b).
- the length of the lower parallelograms (111a) (111b) will be adjusted by an adjusting means (112a) (112b) so that it is identical to that of the upper parallelograms (101a) (101b); in this way, the wheels will be perpendicular to the ground.
- two supports (404a) (404b) are fixed by bolts respectively (405a) (405b) a sole (406) being fixed, at its ends, to the hubs (94a) (94b) via bolts (407a) (407b) ( Figure 11) and, in its central part, to the supports respectively (404a) (404b), by bolts (408a) (408b).
- the conduct of the skate with tracks is different from that of the roller skate. It will be necessary to lift the feet and operate by sliding on the ground by pressing on the heels and lifting the toes.
