Definitions

  • the present invention relates to a wheel, in particular for a sports device, according to the preamble of claim 1.
  • the invention relates to a wheel with a rim, with a tire held on the rim and with resilient support elements for the tire on which rests the tire and of which the tire is at least partially supported in its cross-sectional profile.
  • a form of sports equipment are those that allow a ski-related descent on snow-free slopes, so serve for so-called grass skiing.
  • Such sports equipment is generally constructed similar to skis, i. they are elongated with a binding for attachment to a shoe, but have at least two rollers instead of the running surfaces of skis.
  • grass skiing is done on meadows and thus requires a sufficiently smooth surface, which is largely free of obstacles.
  • grasshopper is also to be extended to activities in rougher terrain, i. for example, on descents on gravel forest roads and other subsoil.
  • the sports equipment and in particular the wheel of such a sports equipment according to the invention should therefore have a largely off-road behavior, so that one is not bound to the use of meadows.
  • Another requirement that is made of a sports equipment is that the mastery is as easy to learn and that the driving behavior pleasant and the movement is physiological as possible to avoid damage to the musculoskeletal system.
  • a generally perceived as very pleasant movement that meets the above requirements, is itself during deep snow skiing with skis adjusting. It is therefore desirable to provide a sports equipment that comes as close as possible to a ski in its driving behavior, which is driven in deep snow.
  • the behavior during turning and during load changes is intended to simulate deep snow driving.
  • a wheel which can be used for inline skaters.
  • This wheel has an outer rim, which is resiliently mounted relative to an inner rim to cushion shocks.
  • a wheel is known, which is also intended for inline skaters.
  • a toroidal tire is provided, which can rotate about its own axis and thus enables a correspondingly braked sideways movement of the wheel.
  • Object of the present invention is to develop a wheel of the type described above so that a simple and inexpensive production is possible and a reduction in weight can be achieved. Another essential task is to prevent the occurrence and transmission of vibrations as far as possible and thereby achieve a protection of the joints of the user.

  • the wheel of the invention has a very simple structure and is therefore easy to produce. At the same time with such a wheel excellent off-road capability is achieved, which offers the possibility to realize a driving behavior, which in combination with corresponding sports equipment has an experience that is largely similar to driving in deep snow.
  • a certain transverse force which acts on the wheel transversely to the direction of travel, a stable directional stability is achieved. With larger transverse forces but still takes a deformation of the tire in the footprint, so that the wheel receives a component of movement transverse to the actual direction.
  • the transverse force limit from which the transverse movement begins depends on the load on the wheel and the size of the movement component decreases transversely to the direction with increasing inclination of the wheel relative to a vertical plane, a substantial match with the deep snow skiing is achieved.
  • the support elements deform differently depending on the direction of the lateral force.
  • the preferably tongue-shaped design of the support elements it is possible to vary the bending stiffness as a function of the distance from the bearing section as desired by the width or the thickness of the support elements is varied accordingly. In this way, the deformation behavior and thus ultimately the handling of the wheel can be influenced as desired.
  • the above-mentioned advantages can be further enhanced by biasing the support members circumferentially against the tire.
  • the support elements are arc-shaped.
  • a particularly pleasant driving behavior of the wheel according to the invention results from the fact that the support elements support the tire at least approximately in its entire cross-sectional profile.
  • the support elements are integrally formed on the rim. In this way, fasteners or other precautions for attachment of the support elements are not required.
  • the connection of the support elements to the rim can be done in different ways. Thus, there is the possibility that a support element extends from the first bearing portion of the rim through to the second bearing portion of the rim.
  • a particularly simple production and an equally simple assembly can be achieved in that the support elements are arranged cantilever-like on the rim. In this case, the support elements may be wedge-shaped towards their free end.
  • the support elements are arranged on the first and the second bearing portion so that the free ends of the support elements of these two bearing portions are aligned diametrically opposite each other. In this case, the free ends of the support elements can touch. It is also possible that the free ends of the support elements have a distance from each other. Alternatively, it may also be provided that the support elements of the first bearing section are arranged offset in the circumferential direction to the support elements of the second bearing section, so that the free ends of the support elements of the first bearing section in the distance space between two consecutive support elements of the second bearing section have.
  • the support elements of the first bearing section with their free ends touch the free ends of two consecutive support elements of the second bearing section.
  • the support elements can have a distance from each other both in the axial direction and in the circumferential direction.
  • the support elements after manufacture of the rim are attached thereto by a suitable manufacturing step, such as gluing, ultrasonic welding and the like.
  • a particularly simple production can be achieved, in particular with a cantilever-like configuration of the support elements on the first and the second bearing portion of the rim, by virtue of the fact that the support elements are integrally connected to the rim.
  • the support elements can be designed to be resiliently deflectable both in the circumferential direction and in the radial direction. Is particularly advantageous it, if the support member are at least approximately in the radial direction to the wheel axle to spring deflected.
  • the deflection path of a supporting element can be designed to be undefined.
  • the Auslenkweg a support element it is also advantageous if the Auslenkweg a support element by a stop, in particular provided on the rim, preferably integrally molded projection is limited.
  • a further increase in stability can be achieved in that the support elements in the region of the bearing sections have recesses for receiving and guiding the tire.
  • both groups of support elements each extend beyond the middle end of the wheel to the opposite side.
  • a support member of the second group is arranged, and vice versa, when in the circumferential direction of the wheel between each two support elements of the second group, a support member of the first group is arranged.
  • the individual support elements of the first group, or of the second group engage with each other in a tooth-like or comb-like manner, but without touching each other. In this way, a uniform deformation behavior is achieved over the circumference of the wheel.
  • a support element of the first group rests on a support element of the second group.
  • the lateral symmetry is ensured in particular by the fact that in the circumferential direction alternately a support elements of the first group rests on a support element of the second group or a support elements of the second group on a support element of the first group.
  • a limitation of the compression is achieved in that the support elements have stop projections.
  • the spring rate of a single support element can be influenced in various ways. Thus, on the one hand there is the possibility that the spring rate of a support element is adjustable by the choice of material. Additionally or alternatively, it may further be provided that the spring rate of a support element is adjustable by the geometry of the support element.
  • the rim when the rim is made in two parts and consists of two halves, which are preferably connected in the region of the median plane of the wheel.
