Definitions
- the invention relates to a sports device, in particular skateboard, according to the preamble of claim 1.
- the sports equipment in particular a skateboard, a chain drive with chain links, wherein the chain links are at least partially bevelled and / or at least partially formed flexible.
- the steering of the sports device can be done, for example, by shifting the weight of the user like a skateboard. But there are also other steering options conceivable.
- the chain links can be made of any material, for example wood, metal, plastic and / or rubber, but also of other materials.
- the chain links can also be formed from a plurality of materials.
- the sports equipment may have other components, such as a frame to which a support board may be attached, on which the user can stand.
- the chain links can be chamfered at least in regions or at least partially bevelled or at least partially chamfered and at least partially flexible.
- the chain links have slanted regions and / or elastic regions laterally at their ends.
- the term "flexible and elastic” is used interchangeably.
- the chain links may be formed completely beveled and / or formed completely flexible.
- the beveled regions and / or the elastic regions of a chain link can be formed identically.
- all chain links are identical.
- the bevelled areas can be angled to the horizontal, preferably with an angle of> 1 °, more preferably> 5 °, most preferably> 10 °, even more preferably> 15 °, most preferably> 20 °.
- the bevelled areas are round.
- a circular design can mean that they are circular or elliptical, at least without edges or corners.
- the chamfered areas are formed tapering outwardly. As a result, the resistance is particularly efficient reducible.
- the chain links may have in the center a horizontally extending section with a horizontally extending surface.
- One or more bevelled and / or elastic regions may adjoin this portion outwardly.
- This horizontal section advantageously allows good contact with the ground and thus improved power transmission.
- it may be provided that the length of the chamfered areas of a Chain link is greater than the length of the horizontal section. As a result, the resistance can be reduced to a minimum when cornering.
- the sports equipment on a conical barrel roll can taper towards its two ends.
- the sports equipment can also have several barrel rolls.
- the barrel roller can be arranged in particular with its longitudinal axis perpendicular to the longitudinal axis of the sports equipment.
- their two ends can be flush with the outer end of the chain links.
- conical is meant tapering or tapering.
- the chain links can rest in particular only on a part of the surface of the barrel roller. It should be noted that at a certain time in operation only a part of the chain links at all comes into contact with the barrel roller and the other chain links are not in contact with the barrel roller. When driving straight ahead, the chain links that contact the barrel roller at the time contact the barrel roller in its central area.
- the barrel roller is arranged in the rear direction, whereby an improved steering is possible. If the sports equipment can drive both backwards and forwards, then a barrel roller is arranged both at the rear and at the front, so that optimal steering is possible in both directions of travel.
- the barrel roller contacts the chain links with its lower surface, wherein the barrel roller is arranged above the chain links which contact the ground.
- the sports equipment on a circulating belt which is provided with a plurality of chain links.
- the band is elastic and flexible;
- the chain links are elastic and flexible.
- the chain links are designed to be resilient and pliable so that, when the user displaces the weight, the chain links may be bent to reduce the contact surface between the ground and the chain links.
- the frictional resistance during steering can advantageously be considerably reduced, so that the energy expenditure can be advantageously reduced.
- FIG. 1 schematically shows a part of a sports equipment 1 in a perspective view from above according to a first exemplary embodiment.
- the FIG. 1 shows a chain drive for the sports equipment 1 with a plurality of interconnected chain links 2, which are arranged parallel to each other in series and rotate about a roller 4 and other rollers, not shown.
- the FIG. 1 shows a rear portion of the sports equipment 1, wherein the sports equipment 1 can move in the direction of travel F shown with the arrow or moves.
- the chain links 2 have centrally a horizontally aligned region 5, with which the chain links 2 touch the substrate, not shown. Beveled or rounded areas 3 are arranged at the two lateral ends of the chain links 2.
- FIG. 2 shows a part or a chain drive of a sports equipment 1 according to a second exemplary embodiment.
- the interconnected chain links 20 are flexible or elastic, at least in its two ends.
- the chain links 20 have flexible or elastic regions 21 (see FIG. 4 ).
- an upper roller 40 and a barrel roller 30 arranged at the bottom are arranged.
- two wheels 50, 51 are indicated by way of example, over which the chain links 20 are continued. The chain links 20 thus rotate around the rollers 40, 30, 50 and 51 during operation.
- the barrel roller 30 is tapered toward both ends so as to taper toward its outer ends.
- Reference numeral 31 designates an end face 31 whose cross section is smaller than the cross section of the barrel roller in the central region.
- the barrel roller 30 contacted in the straight ahead (see FIG. 3 ) With its central region, the chain links 20, so that an optimal power transmission between the barrel roller 30 and the chain links 20 is possible.
- the chain links 20 are arranged parallel to one another in this embodiment also in succession.
- FIG. 3 and FIG. 4 show the sports equipment 10 in a side view.
- the chain links 20 are bent in the bent portions 21, so that the bent portions 21 abut against the conical ends of the barrel roller 30.
- the sports equipment 10 tilts on the bent portions 21, whereby the contact surface and the frictional resistance between Chain links and underground are minimized.
- FIG. 5a shows a third embodiment of the present invention in a perspective view from behind when driving straight ahead in the direction F.
- FIG. 5b shows the third embodiment in a side view and
- FIG. 5c shows the third embodiment in a side view when cornering.
- the sports equipment 100 comprises a revolving belt 6 which is provided with a plurality of chain links 200.
- the band 6 is elastic and flexible;
- the chain links 200 are elastic and flexible.
- an upper roller 40 and a barrel roller 30 arranged at the bottom are arranged in the rear region, that is to say that region which faces away from the direction of travel F.
- two wheels 50, 51 connected via an axle 52 are indicated, via which the chain links 20 are continued.
- the chain links 200 rotate or the circulating belt 6 thus rotates around the rollers 40, 30, 50 and 51 in operation.
- the barrel roller 30 is tapered toward both ends so as to taper toward its outer ends.
- Reference numeral 31 designates an end face 31 whose cross section is smaller than the cross section of the barrel roller in the central region.
- the barrel roller 30 contacted in the straight ahead (see FIG. 5a and 5b ) With its central region, the chain links 200, so that an optimal power transmission between the barrel roller 30 and the chain links 200 is possible.
- the chain links 200 are also arranged parallel to each other in this embodiment in succession.
- FIG. 5c a turn to the right is shown.
- the chain links 200 are bent in the bent portions 21, so that the bent portions 21 abut against the conical ends of the barrel roller 30.
- the sports equipment 100 tilts on the bent portions 21, whereby the contact surface and the frictional resistance between chain links and ground are minimized.
