Abstract

A footboard of a skateboard is with respect to a respective reference plane which at riding straight (= x plane) is parallel to the riding path (= the ground), and at turning (= x'' plane) is with respect to the direction of riding slanted to one or the other side, is rhythmically swung around a longitudinal axis (O) of swinging lying in suspensions (4, 5) of the skateboard. The amplitude (A) and the frequency of swinging are mutually coordinated in a manner that swinging does not result in such meandering of the skateboard, which was felt inconvenient. To a socket shaft housing (8) of a suspension (4, 5) of the skateboard, said housing encasing a roller shaft (11), there is to each end thereof attached a gearing (9, 10), the gearings designed mirror-symmetrically. The gearing (9, 10) is composed of an essentially three-part housing assembly, which comprises a mounting casing (13), an upright intermediate wall (16) and a mounting cover (17), as well as of a train-type gearing composed of a toothed rack (19) as a driving constituent and a gear (25) bound to the roller shaft (11), as a driven constituent. In addition to the roller shaft (11) which passes through, two further, inner shafts (14, 15) constitute said gearing, the lastmentioned shafts each supporting two gears (20, 21; 23, 24), the first one (20) thereof mating the toothed rack (19) and the last one (24) mating the gear (25) driven. The second one (21) of the gears is indirectly connected to the respective shaft (14) by means of an overrunning clutch (22), and shaft (14) is by means of a suitably pre-stressed helical torsion-spring (28), which encompasses the shaft (14), rotationally-elastically bound to the stationary mounting casing (13) of the gearing.

BACKGROUND OF THE INVENTION

In its basic shape a suitably warned tread plate, two pairs of rollers (rollers) are underneath i i 1. Optionally, the skateboard can also be equipped with additional equipment such as a brake, a torch, a flashlight, a pointer, a tail light, a bumper, etc. Normally, when skateboarding, turning is allowed on a sktabcard footboard that is parallel to the skateboard track when driving directly. on one side or the other with respect to the longitudinal axis. This action can be ensured by a special roller hinge, and when cornering, the tilt of the tread plate results in the inner and outer rollers approaching each other on the front and rear rollers, while the other, i.e., the rollers, are relative to the bend. zooms out.

Obviously, the skateboard's own drive is done by pushing the rider away from the ground or by driving with the ends, so that the rider as a sanctuary ose nu ί <

There are known attempts to assign to a system a skateboard rider the nature of a physical phenomenon without using gravitational force or a special energy source, i.e. from e r and z 1 and children.

-, common action

U.S. Pat. No. 4,915,495 discloses a skateboard whose tread plate is divided laterally into a rear pedal section in a divided extension. The above-mentioned sections of the tread plate are interconnected by a skateboard frame. Here, the pedal section is coupled with the possibility of transmitting movement by means of couplings comprising a push rod, a crankshaft, and a toothed segment, as well as by means of a gear connected to said toothed segment, and is able to fall asleep. four pairs of ubiquit wheels and an end gear that is connected to the roller shaft of the skateboard rear rollers, connected to the shaft by means of overhangs in? i i with τ η β.

According to the above solution, a skateboard provides substantially the same height as skateboards without drive gears, and is monitored for various functional options such as ease of cornering and maneuverability.

In the previous solution, the height of the skateboard can only be discussed in conjunction with the front, i.e., fixed section of the skateboard wear pad, that is not in connection with the rear, i.e., pedal area, except in the pedal function locked position. primary objective or subject of resolution. Analogously with respect to the various options, the following should be noted here: The curves can be easily overcome and the skateboard can be easily handled only if the pedal function is locked (i.e. both sections of the tread plate are straightened in the same plane). In a state where the front fixed section of the forefront is forward (the skateboard is physically pushed forward, only the rider's foot resting on the footboard section remains in execution normal (normal) - the possibilities provided by skateboards between the driving gears). The possibility of jumps is completely eliminated when the pedal section is raised.

The gear 20 is positioned inwardly inside the housing 17 and extends into a corresponding circular recess -6 of the wall 16, while the gear 21 accompanied by the overrunning clutch 22 lies inside. and is located axially spaced from the rotatably mounted shaft 14. The intermediate shaft 15 supports a gear 23 designed to engage with a toothed wheel 21 whose diameter is larger than the previous one, and on the side facing the vertical wall portion of the housing 13 supports a further, larger gear 24. Both gears 23 24 are directly connected to the intermediate shaft 15. The roller shaft 11 carries a toothed design designed to engage with each other; the diameter is greater than the diameter of the gear 25. The interconnection of the gear 25 and the shaft 11 is also direct. Naturally, as well as the recesses 26, in the wall 16 there are also projections for guiding the shafts 11,15. In addition, the wall 16 comprises a vertical trough-shaped guide 27 (FIG. 6) for receiving and guiding the vertical rack 19, the inner profile of the guide 27 coinciding with the recess iS.

On the other hand, a suitably biased spring torsion spring 28 is provided by the shaft bearing 24, the end of which is formed as a hinge and is connected tangentially to the surface of the shaft 14 to this shaft and whose other end is designed. as a special hook and connected to the housing 1 3. Thus, the coils of the spring 28 pass so that they are tensioned when the rack 19 moves downward, i.e., accumulates the potential return of the rack, to energy po19. It is clearly necessary to see in FIG. 5 that, in the case of the existence of two transmissions (j) connected to a corresponding roller shaft 11, one of the two springs 28 is wound in right-hand rotation and the other is wound in left-hand rotation. The left-hand helical coil spring 28 -9 is shown in FIG. The gearbox is designed on the principle that a single stroke of the toothed rack 19 results in a single revolution of the shaft 14. At full rotation of the shaft 14, the coils of the spring naturally do not fully close its housing surface and thus the spring storage capacity is not exhausted. the mutual connection of the shaft 11 and the roller 12 is taken over in the technique b0; In a preferred embodiment of the invention, the overrunning clutch 23 belonging to the cylinder 24 in respect of the overrunner 22 is selected not by the clutches which are solved by the rings interposed to each other bearing a corresponding row of roller needles, As a result of a recent dispute, the brothers know a different storyline of the eagle owers with two mutually movable-or each other, each of which (the TORRINGTON's inclined sections are formed in the outer ring). The two overrunning clutches 22 of the rollers 12 connected to the common shaft tak1 thus operate in the same direction of rotation. Figures 1 to 6 show the condition of the skateboard which is neutral with respect to the tread plate 1 and which is balanced 28. The four racks 19 are pressed P e · i with respect to the spring upwardly to the tread plate 1 under the spring z8 in 11v. FIG. 7 schematically illustrates the state of a skateboard which CDs a tread plate 1 tilted to one of the limiting positions by force, and FIG. 8 shows a state corresponding to a tilt of the tread plate of the other limiting position. The two springs 28 relative to the racks 19, which are pushed down by the tread 1, are then tensioned (exposed to tension), the other two being freed accordingly. It goes without saying that the states of Figures 7-8 signify overcoming the turns of the skateboard dc in one direction or the other of the 13th reversal coordinate system with the X-ray plate Fig. 7 comprises three inches coupled to the oscillation axis 0 of the tread plate 7. The system xv indicates the position of the tread plate 7 when driving straight, the system x '- y' has its position at extreme rotation in one direction (analogous to the extreme rotation in the other direction is shown in Fig. 8), and system x '-v Optional intermediate turn position of the skateboard, ie slight turn. The arc arrows A attached to the y, y ', y' y coordinate planes in Fig. 7 undermine the ability to pivot the treadmill p, i, eo uraanicvvm skateboard, with a pivot amplitude always reasonably controlled. In principle or preferably, it is assumed that substantially the same angle, even if the fall of all arrows A, is the choice of swivel range cc such handling of the driving technique by the user, and said range depends both on performance and driving characteristics, and is structurally limited to one. or, on the other hand, only by the extremely leg deflection position shown here by the x'-y1 system. The swinging of the tread plate 1, as explained above in accordance with the basic concept of the invention as defined in the introduction, is used within the range of angles indicated by the arc arrows A to generate a skateboard driving effect. Indeed, experiments have shown that oscillation carried out with a purposefully low amplitude with respect to individuality (frequency and with a high selection, of course, does not have any effect for us); boundary planes <=> In fact, the skantal indirect ride of the skateboard, in fact, swinging, essentially constitutes the creation of a miniature curve, i.e., deviating along the waveguide meandering path>, but can be used as a suitable base for generating a suitable driving torque. The fact that the gearbox is inevitably realized as light ”is a clear accompanying feature of the concept described above. When both the shafts 1 and the rollers are provided with gearboxes 9, which means that the driving load po is each divided into two bearings, the skateboard as a whole fulfills the rigidity requirements of the type. With a skateboard right away! -11 options are given to start driving either by pushing away from the woman (similar to a skat eboa r house without a drive mechanism), or by stepping on a stepping board and starting to swing the skateboard. so that the gearwheel 19 of the gearbox shaft 14 rotates counterclockwise to the left; the overrunning safety clutch 22 is actuated and therefore the gear 22 also rotates. Rotation of the shaft 14 is followed by tightening of the spring 22. on ezu; I ► ··, C.i I- · ·. The gear wheel 4 is guided when the toothed wheel 14 is guided, i.e. it is guided. 7 ozutenenc t c 2 v · .. ;; é k 0 C J. more specifically, the drive of the driven wheel is deliberately driven by the steering wheel; of the described working center of the toothed wheels of the roller shaft and the rotating torque is thus driven by this wheel; rollers. Of course, the gear 25 and the shaft 11 will be rotated to the left; the overrun safety clutch 30 of the roller 12 is actuated. As a result of the described transmission, the engagement dc of the rack 19 is converted into a driving rotation of the roller 12. The above-mentioned pop 19 of the transmission 9 of the transmission 10 belonging to the same; __ lifting of the skateboard wear plate under the influence of the unwinding force of the respective spring. In this case, the coupling of the shaft 14 and the gear 21 of the gearbox 10 is broken by means of an overrun safety clutch. When rotating, especially in sharp turns, the difference between the rotational speed of the outer rollers and the inner rollers 12 cannot in principle be neglected. It is not excluded that in the case of the above swinging, also during the skateboard rotation, which rotates more slowly, i.e. the number of revolutions of the outer roller may exceed that actually achieved. In this case, the safety clutch (0 O) runs over: o the roller allows it to rotate freely. Naturally, uU deflection fuses are also needed to drive the skateboard backwards without engaging the drive gearboxes. From the above explanations, it is evident that the apex portion with respect to the underside of the wear plate 1.
