The process of creating a self-propelled skateboard and skateboard physical system to perform the process

The present invention falls within the field of sports / games / recreation and, in the context of this, concerns skateboards, in particular those which provide for dedicated, integrated measures for the physical propulsion of skateboards. (Int. Cl. ⁴ : A 63 C 17/12, B 62 M 1/08)

In its original design, the roll includes an elongated, purpose-built walking board, with two pairs of wheels suspended from below (optional accessories, such as a brake, flywheel, lamp, marker, bumper, etc.). It is normal for the skateboard to allow it to be turned while driving if the board, which is parallel to the runway, is tilted to one side or the other with respect to the longitudinal axis of the skateboard. This is made possible by the suspension of the wheels, which brings the front and rear inner wheels closer to each other when cornering, and the front and rear outer wheels distance each other.

It is understood that this is propulsion by foot bouncing (or downhill) and that the skateboarding system can be considered as a physical concept, ie, when the skateboarder and the skateboarder are functionally integrated into a complete, sovereign entity, we can speak only in the phase of utilization of the previously introduced energy of mass inertia (or in the case of skateboarding: using the force of gravity).

Attempts have been made to give the skateboarder the character of a physical concept without the aid of gravity or. a special source of energy, therefore, solely on the physical engagement of the skateboarder.

Thus, US Patent 4,915,403 (Wild et al.) Discloses a mechanically actuated skate whose board is transversely divided into a front, fixed section and rear, pedal section in the middle of the longitudinal dimension of the skateboard. The aforementioned right sections link the skeleton frame (chassis). The pedal section is through a joint mechanism comprising a coupling, a lever, a crankshaft and a segment sprocket, and to a segment sprocket of a pinion gearbox comprising four pairs of sprockets and a pinion, a wheel-joint connected to the wheels by a wheel-joint connected to the wheels. , which are each connected to the shaft by a one-way clutch.

According to the antecedent file, the skateboard has the same height as the skateboards without a propulsion laptop, and various useful features are preserved, such as the skateboard. ease of bending and maneuverability.

In the antecedent solution, the height of the skateboard can only be discussed in relation to the front, fixed plate section of the skateboard, and in relation to the rear, pedal section, not or. only if its pedal function is switched off, which is not in line with the original purpose or purpose. goal. The same applies to the following useful features: bends can be easily overcome and maneuvered only when the pedal function is off, i.e., when both right sections are aligned. In the condition that the skateboard is physically driven, the skateboard for normal skateboarding (normal in terms of the possibilities offered by the skateboard without a gearbox) is left with only the foot that stands on the front rain section. The maneuverability is obviously and not badly affected. It is completely excluded e.g. the ability to perform jumps when the pedal section is raised.

The antecedent solution is limited to the size of at least two foot lengths with respect to the length of the skateboard. There is a significant risk of turning to one side or the other depending on the direction of travel, as well as backwards through the rear wheels (the drive operates in the sense of lowering the skateboarder itself).

A well-known solution, however, in operational terms, demonstrates another insignificant disadvantage, namely the drive torque is introduced intermittently: the drive phase is followed by the reactive phase, this again by the drive phase, etc.

The object of the invention is to avoid the disadvantages identified above and to create a skateboard that can be physically driven in the course of movements such as that of a skateboard user without a propulsion laptop.

Taking into account the fact that, for curving purposes, the skateboard is tilting within limits whose extreme values are limited by design and that the rocking board is reasonably small with respect to a plane which is straight, horizontal, when driving inclining to a bend in the direction where the geometric center of the bend lies, practically does not cause a noticeable turn of the skateboard, the invention is based on the problem of how to turn that rocking of the board into drive of the skateboard wheels.

According to the invention, the method of creating a self-propelled skateboard-based skateboard physical system comprising a gearbox for converting the skateboard's action force into torque to drive the skateboard, and a suitably (at least minimally) skateboard, characterized in that the skateboard to the selected system plane, which is parallel to the runway when driving, and is inclined to one or more angles, depending on the direction of travel. the other side, rhythmically swinging around the longitudinal articulating axis, located in the skeleton suspension. In this case, the swinging amplitude, which is preferably as small as possible, and the swinging frequency, preferably as high as possible, are so mutually compatible that the swinging does not result in interfering motion of the skate.

A roller for carrying out the process as defined above and comprising a pivot joint between the skateboard and the roller shaft, each roller skate being connected indirectly via the one-way clutch to the roller skate, according to the invention is characterized in that - in principle - a tubular nozzle of the right-hand suspension at each end of the skirt, one transaxle at each end, of the skeleton of the skeleton.

According to the invention, the same type of roller is in the preferred design, characterized in that a tubular nozzle of each of the right hangers at each end of the skeleton is connected to one end of the gearbox at the ends of the skeleton.

Regardless of the principle or preferred design of the skateboard, the gearboxes relating to the front and / or rear wheel axles are mirrored symmetrically with respect to a longitudinal, erect, right-hand running plane. In this case, each laptop consists of:

with said tubular attachment of a connected box carrier, which is closed in the direction of the associated roller wheel by an upright wall, to which - by pointing towards said carrier - a housing cover is attached, provided that the bearing box seats are provided in the box carrier and housing cover. shafts and gearbox shafts, erect, through a cutout in the ceiling wall of the housing cover up to the right skateboard and extending with a guide rail connected to said intermediate wall, guide gears, a stepdaughter engaging with a gear rack and gear couplings in a gear-locking connection and a wheel shaft, the last of the said gears being arranged on the wheel shaft, and the return, screw-bending springs, the connecting pinion shaft and said box bracket by tightening the said spring in the downward movement of the toothed rack, the adjacent gearbox sprocket with a common transmission shaft connected to them indirectly via o Suitable single-clutch couplings.

The invention will now be described in greater detail on the basis of the embodiment shown in the accompanying drawings, in which FIG. 1 is a perspective view of the skateboard, the skateboard being substantially cut out to show the skeleton chassis; FIG. 2 is a skeleton of FIG. 1 in a side view, on the left (= front end of the skateboard) in an upright cross section across the laptop, FIG. 3 shows a skeleton of FIG. 2 in the left view (= from the front) and in the area of the front right wheel in an upright axial section extending along line III-III of FIG. 2, with attached gear rack (one of the shafts with associated gears is omitted to avoid overcrowding), FIG. 4 is a cross-sectional view taken along line IV-IV of FIG. 3, FIG. 5 in a fixed axis of the skateboard (front or rear) tied gearbox pair (without gears) in spatial projection, FIG. Fig. 6 shows the gearbox according to the direction of travel to the right, in the partially disassembled state and in the spatial representation; 7 shows the skateboard in front (or rear - anyway) from one side to the extremity of the skateboard when cornering, with an outlined rocking geometry, and FIG. 8 is analogous to FIG. 7, except that it is a slope to the other side.

The roll comprises a board 1 which is assembled and designed for the purpose and to which the front undercarriage assembly 2 is suspended at the front end and the rear undercarriage 3 at the rear. The union of the board 1 and the undercarriage assemblies 2, 3 is direct, as in the case of rollers without built-in drive laptops.

The undercarriage assembly 2, 3 is based on a two-pillar suspension 4 (front), 5 (rear), which as such is taken from the prior art. Suspensions 4, 5 are identical in structure to one another, but arranged in a known manner mirror-symmetrically with respect to an upright intermediate plane placed transversely to the direction of travel of the skateboard. In the presentation of FIG. 1, this structural feature is reflected by the fact that from the two-pillar suspension 4 of the front undercarriage assembly 2 a rigid, rotatable and fragile pillar 6 is visible, and from the two-pillar suspension 5 of the rear undercarriage 3, the pillar 7 is elastically extending.

The pillars 6, 7 of each suspension 4, 5 are arranged in a K-layout in the central longitudinal upright plane of the skateboard, which, in combination with other features of the pendants 4, 5, allows the front, when tilting the board 1 to the left or right, depending on the direction of travel of the skateboard the undercarriage assembly 2 and the rear undercarriage assembly 3 counter-rotate, each in turn rotating its own upright axis, coincident with the axis of the rigid pillar 6, which means, in operational view, a roll of the skateboard.

With the exception of the aforementioned mirror arrangement of the suspensions 4, 5, the front undercarriage assembly 2 and the rear undercarriage assembly 3 are identical, and to simplify the description of the skeleton, therefore, only the undercarriage assembly 2 and only the suspension 4 will be discussed in the following.

According to the invention, on each side of the tubular attachment 8 disposed at the root of the K-arrangement of the pillars 6, 7 hangs 4 crosswise on said pillars, one drive gearbox 9.10 is connected, each of which is suitable for mirror symmetry in relation to the gearboxes 9.10. the central upright longitudinal plane of the skateboard.

Through the tubular nozzle 8 and the transmission 9, 10 passes the wheel shaft 11, which carries the roller wheels 12 at its free ends.

The arrangement of gearboxes 9.10 in pairs for each shaft 11 is realistically necessary in order to accomplish the task of the invention. The arrangement of the laptops on both beams, i.e. front and back, it is in principle optional, and the experiments and consideration of practical aspects (this will be discussed later) nevertheless lead to the conclusion that it is advisable to anticipate two pairs of laptops, as presented in Figs. 1. The potential initial concern that laptops in this arrangement may represent an inadvertent construction overload of the skateboard is to be eliminated, inter alia, in the knowledge that the hangers, which are commonly known as "critical" and therefore expensive skate components, are not of the invention should be divided into front / rear or. left / right, as is the case with the prior art.

The gearbox 9 according to the invention consists of a box housing bracket 13 connected to the free end of the tubular attachment 8, in which, in addition to the wheel shaft 11, there is also a gear shaft 14, which is arranged expediently above the wheel shaft 11, and an intermediate gear shaft 15, which is arranged according to the invention. height between the shafts 11, 14, but shifted back with respect to the direction of movement of the skateboard. The carrier 13 is closed on the side of the roller wheel 12 by an upright adaptive wall 16 (see also Fig. 6). Lastly, a housing cover 17 is attached to the latter, in which a second set of bearing positions for shaft mounting 11, 14, 15 is provided. In the ceiling section of the housing cover wall 17, it is adjacent to the wall 16

Rez provided cutout 18 for the transition of the toothed rack 19, as will be explained later.

The shaft 14 bears a pinion 20 which is directly connected to it and is intended to cooperate with the rack 19, and a further pinion 21 which is indirectly connected to the shaft 14 via a clutch 22 for one-way switching. In this case, the sprocket 20 occupies the space inside the housing cover 17 and extends into the adapted circular cutout 26 in the wall 16, and the gear 21 with its clutch 22 is located in the space inside the carrier 13 at an axial distance from the bearing of the shaft 14.

The intermediate shaft 15 bears a sprocket 23 which is adapted for engagement with the sprocket 21 and, with respect to the diameter of the latter smaller diameter, and a further larger sprocket 24. The sprockets 23, 24 are provided with an intermediate shaft 15, facing the supporting wall of the carrier 13. directly connected.

Shaft 11 bears a drive gear 25 which is adapted to be driven by a gear 24 and is smaller than the diameter of the latter. Also, the union of the sprocket 25 and the shaft 11 is direct.

It is understood that, by analogy to the cut-out 26, there is also an adapted cut-out in the wall 16 for the passage of the shaft 11, 15. In the rest, the upright trough guide 27 (Fig. 6) for receiving and guiding the upright rack 19 is also provided, whose luminous cross-section coincides with the notch 18.

The shaft 14 is in the axial space between the gear 21 or. its clutch 22 and shaft 14 are provided with a suitably biased helical spring 28, one end of which is tangentially close to the surface of the shaft 14 and connected to the latter, and the other end is connected to the carrier 13. These springs 28 are arranged in such a way that they are tightened when moving the toothed rack 19 towards the ground, ie accumulate the potential energy required to return (raise) the strip 19. FIG. 5 it is clear that in the case of two, on the selected wheel shaft, 11 coupled gearboxes 9.10, one of the springs 28 is left- and the other is right-hand. An example of a left-handed coil spring 28 is illustrated in FIG. 6.

The laptop is designed on the basis that the working stroke of the toothed rack 19 corresponds to one rotation of the shaft 14. It is understood that the spring 28, at full rotation of the shaft 14, does not yet fit on the mating surface of the latter and that its spring-accumulation capacities are not fully utilized.

The connection between the wheel shaft 11 and the wheel 12 is drawn according to the state of the art and is based on the roller bearing 29 (Fig. 3) and the clutch 30 for one-way start-up.

In a preferred embodiment of the invention, both the clutch 30 for the one-way engagement of the wheel 12 and the clutch 22 for the one-way engagement of the sprocket 21 are selected from the known coupling, which is based on two interposed, mutually movable rings, each of which carries its own set of rolling pins , the steep sections being in the outer ring (TORRINGTONj patent. It is understood that the clutches of 22 wheels 12 bound to the same shaft 11 act in the same way.

Figs. 1 to 6 refer to the condition of the skateboard, which is neutral from the point of view of board 1 and equilibrium from spring 28. The toothed rails 19 are pressed up against the plank 1 under the influence of the return forces of the springs 28.

On the contrary, in Figs. 7 shows the skate condition when the board 1 is forcibly inclined to one extreme, FIG. 8 is a situation where board 1 is forcibly tilted to the other extreme. On the downward side of the toothed rack 19, the respective springs 28 are tensioned (tightened) and the remaining two are relieved (released). As is known, it is in the state of FIG. 7-8 to roll with the skateboard one way and the other.

In FIG. 7 shows three plane-coordinate systems that are tied to the rotation line O of the board 1. The system xy indicates the position of the board 1 when driving the skateboard straight, the system x'-y 'indicates the position of the board in a very sharp turn in one direction (analogously for the other direction - Fig. 8), while the system x ”-y” illustrates some intermediate state of roll, some slight turn. The separate arrows A in FIG. 7, plotted against the y, y '> y' ordinate planes, indicate the possibility of reasonably measured swaying of plank 1 relative to the respective ordinate plane while driving the skateboard. In principle or. it is reasonable to assume that, in the case of all arrows A, they are essentially the same size as the tilting movement, in fact the dimension of tilting as such is left to the individual will or. mastery of skateboarding by the user or it is causally dependent on the performance and driving conditions and is limited in construction to one side or the other only by the extreme tilting position illustrated here by the x'-y 'system.

According to the aforementioned basic concept of the invention, said pitching of the board 1 in the range of angles indicated by separate arrows A is used to generate the drive of the skateboard. The experiments show that swinging at a sufficiently high frequency and at a reasonably small amplitude around an arbitrarily chosen plane y, y ”without, of course, exceeding the boundary plane y 'does not lead to a dangerously restless roller skating (the swaying is, in essence, the creation of tiny turns), however, it is an appropriate starting point for generating suitable torque. That the laptop 9 is necessarily lightweight is actually an obvious accompanying feature of a given starting point. By equipping both wheel shafts 11 with gearboxes 9 and therefore dividing the load load into two gearboxes 9 each time, the skateboard fully meets the robustness requirements that are typical for this type of article.

The skate according to the invention enables starting by sliding off the floor (as in skateboards without a drive mechanism) or by stepping on it and starting by tilting the skateboard.

When pushing the rack 19 of the gearbox 9 down, the shaft 14 rotates in the opposite direction; the clutch 22 engages and thus rotates the sprocket 21. The rotation of the shaft 14 causes the spring 28 to tighten. From the sprocket 21, the torque is transmitted to the sprocket 23, through it to the intermediate shaft 15 and thereby to the sprocket 24, which rotates in the clockwise manner. sense. The torque is transferred from the gear 24 to the output gear 25 and then to the wheel shaft 11. The output gear 25 and the shaft 11 are then rotated counter-clockwise; the clutch 30 for directing the wheel 12 is engaged. The result of the described transmission is that the gearing of the toothed rack 19 is converted into drive rotation of the wheel 12.

Simultaneously with the operation of the gear stroke 19 described above, the gear lath 9 of the gear lath 10 of the gearbox 10, which engages the same wheel shaft 11, is subjected to the lifting of the right skateboard by the force of the corresponding spring. In this case, the connection between the shaft 14 and the gear 21 of the gearbox 10 is broken by means of a one-way clutch.

When cornering, especially sharp, the difference in the speed of the outer and inner wheels 12 is, in principle, negligible. The possibility that the actuator may only actuate the internal, slower-rotating wheel 12 when performing the above-mentioned propulsion, while the outer wheel rotates faster than the speed generated by the laptop is not excluded. In this case, the outer wheel clutch 30 allows the latter to rotate freely.

It goes without saying that the clutches 30 for one-way start-up are also necessary to allow the skate to be reversed as well, then of course without the inclusion of drive gears.

It is apparent from the above embodiments that the top of each toothed rack 19 relative to the lower surface of the board 1 performs a movement (Fig. 8) consisting of a straight, radial component R, which generates a tilting of the board 1 as such, i.e. oscillation of the board 1 about the longitudinal axis O, and the circular component C, which occurs during the rotation of the underpass * - ....

circuits 2, 3 for wrapping purposes, i.e. rotate around the upright system axis 4, 5. To eliminate the risk of possible self-locking between the plank 1 and the toothed rack 19 in the given geometric conditions, a non-represented ball bearing 31 is arranged at the top of each toothed rack 19.
