Definitions

  • the invention relates to a sports device with a two-lane roller device, in particular a skateboard, with at least one roller board and a chassis with two wheel axles connected to the roller board, which has a trailing arm suspension for each wheel axle, which is pivotally connected to the roller board about at least one transverse axis and at the same
  • the wheel axis is arranged away from the first end of the roller board, with at least one elastic element acting against the deflection direction acting on at least one trailing arm wheel suspension.
  • Sports equipment with two-lane rolling devices such as skateboards or the like, has a horizontal rolling board on which wheel axles are more or less rigidly connected via a steering element. Such rolling devices are therefore particularly suitable on smooth surfaces. Shocks due to very small bumps and very small obstacles are transmitted to the roller board user almost undamped, which affects driving comfort. Even relatively small obstacles and bumps, such as chippings, gravel, road grooves or the like, can make the skateboard's driveability considerably more difficult. In the case of medium to medium-sized obstacles and rough terrain, for example unpaved paths or lanes with damaged surfaces, the roller board is even unusable.
  • US 5 100 161 A discloses a skateboard for use off the road, which has vibration damping elements.
  • a vibration damping element is attached between the roller board and a wheel axle.
  • Each vibration damping element consists of a plurality of elastic plates which are connected to the roller board via guide and connecting bolts.
  • These vibration damping elements also have the disadvantage that the spring travel is extremely limited and thus the driveability of the skateboard is very limited in the case of medium and large obstacles, even if further vibration damping own vibration absorbing wheels are provided, which are attached to conventional skateboard wheels. This is primarily intended to make it easy to convert a conventional skateboard into a vehicle that can be used away from slippery roads.
  • the one force application point of the elastic element is arranged in the region of the half of the trailing arm suspension facing the skateboard, preferably in the third of the trailing arm suspension facing the skateboard, particularly preferably in the transverse axis area
  • the elastic element on the trailing arm suspension is movable, preferably pivoted, and that an angle spanned between a vertical axis of the roller board and an axis of the elastic element is not equal to 0 °, preferably greater than I ⁇ 30 °
  • the elastic element is movably, preferably pivotably, mounted on the roller board or a frame element that is firmly connected to the roller board in the region of its other force application point.
  • the elastic element is movably, preferably pivotably, mounted in the region of its other force application point on the other trailing arm suspension.
  • the at least one elastic element can be arranged approximately in the region of a transverse median plane of the rolling device. The elastic element is optimally protected against dirt and contamination.
  • the axis of the elastic element is arranged at least predominantly in the longitudinal direction of the rolling device, preferably in at least one position of the trailing arm suspension approximately parallel to the rolling board (FIGS. 9 to 31).
  • the elastic spring element lies directly under the roller board.
  • a particularly high level of driving comfort in rough terrain is achieved with one elastic element per trailing arm suspension, the elastic elements being arranged side by side on both sides of a longitudinal median plane of the roller board and preferably the axes of the elastic elements in at least one position of the trailing arm suspension approximately parallel to one another. This allows particularly long spring travel of the decoupled elastic elements to be achieved with great ground clearance.
  • the transmission ratio can be further increased by the fact that the trailing arm suspension is designed as a multi-unit gear mechanism that acts as a force translator on the elastic element.
  • the trailing link wheel suspension is designed, for example, as a four-link gear, the trailing link wheel suspension being pivotally connected to the roller board in its end area on the side of the wheel board via two rotatable wheels.
  • the trailing arm suspension is designed as a link chain, two links pivotally connected to each other being connected to each other via an elastic element.
  • the elastic element can optionally be designed as a tension or a compression element.
  • the chassis between the roller board and at least one trailing arm suspension has a steering device which can be actuated by shifting the weight of the user in order to enable a change in the direction of travel.
  • This design has the advantage that the steering device is largely protected against damage and contamination.
  • the elastic element can optionally be designed as a helical, spiral, leaf, elastomer or air spring. Combinations between the types of springs are also possible.
  • At least one damping element acting on the trailing arm suspension is provided parallel to the elastic element, wherein the damping element can be designed as an oil damper, air damper or as a friction damper.
  • the rolling device has two roller boards which are connected to one another in an articulated manner. The steering of the sports equipment takes place by relative rotation of the roller boards to each other, so that own steering devices based on the weight shift of the roller board user can be omitted.
  • the off-road capability and driving comfort can be further increased by the fact that the wheels mounted on the wheel axles have tires filled with compressed air or gas.
  • the use of multi-layer or foam-filled tires is also conceivable.
