Definitions

  • the invention relates to a roller sports device, in particular roller skate, with two pairs of rollers and adjustable steering, with leaf spring-shaped supports, preferably made of flexible plastic, arranged on a base plate, which are firmly connected on one side to the base plate and along the underside of the base plate extend to the center and each have at their free end a bearing for receiving the two-pair rollers with their axis.
  • FR-GM 8202688 and FR-PS 85 11 206 steering structures are described in which the free end of the carrier rests on a fixed support arranged on the base body.
  • the axles swivel out through the acute angle of the carrier to the vertical longitudinal plane and thus cause the roller skate to be steered.
  • the leaf spring-shaped supports are subjected to torsion.
  • US Pat. No. 4,398,735 describes a roller skate chassis in which the leaf spring-shaped supports are made of flexible plastic, which are connected at one end to the base plate and rest on a support at their other free end, the shapes of the supports being chosen in this way can be that the steering properties of the chassis can only be adjusted to the individual requirements of the runner.
  • the hardness is only set in stages due to a certain number of supports.
  • the hardness of the steering can only be changed by a complicated and time-consuming assembly when replacing the supports, and a certain number of supports with different supports are required for each pair of roller skates.
  • the object underlying the invention is form a roller skate with two pairs of rollers and adjustable steering so that the desired hardness of the adjustable steering is continuously adjustable.
  • This object is achieved in that between the base plate and the leaf-spring-shaped support, an adjusting piece is arranged to be continuously displaceable in the longitudinal direction of the base plate, the adjusting piece on its side facing the support having a surface of various widths extending in the longitudinal direction of the base plate, on which the leaf spring-shaped carrier is present.
  • the surface of different widths of the adjusting piece is expediently designed as an isosceles triangle, the base of which is arranged approximately parallel to the axis of the rollers and the tip of which is arranged approximately on a line running in the middle between the pairs of rollers.
  • the leaf spring-shaped support has a horizontal plane with which it rests on the surface of the adjustment piece.
  • the base of the isosceles triangle forming the surface of the adjusting piece corresponds to the width of the horizontal plane of the free carrier and the surface at this point lies at least in its two end regions on the plane, while the tip of the triangle lies point-wise on the plane, the Surface is semicircular.
  • the end of the adjusting piece resting on the underside of the base plate has a is provided in the longitudinal direction of the base plate extending slot in which a locking element locking the adjusting piece engages.
  • the adjusting piece is advantageously designed as a Z-shaped double angle, the upper leg, which is provided with the slot and which is provided with the slot, extends to the center of the basic body.
  • adjustment pieces arranged in the area of the front and rear leaf spring-shaped carrier have a differently designed surface.
  • FIG. 1 the basic structure of a roller skate with two pairs of rollers 5 is shown.
  • the roller skate has a base plate 1. At the front and rear ends of the base plate 1 are extending along its underside towards the center thereof leaf spring-shaped carrier 2, 3 preferably made of plastic. These form an acute angle with the base plate 1.
  • each carrier 2, 3 is provided with a bearing 9.
  • the bearing 9 receives an axis 4 connecting the rollers 5 to each other.
  • the axes 4 can be mounted differently, for example in a plain bearing or in a roller bearing.
  • An adjusting piece 6, 7 is arranged between the base plate 1 and the free support 2, 3.
  • the leaf spring-shaped carrier 2, 3 lies at its free end, preferably on the bearing 9, with its upper region on the adjusting piece 6, 7.
  • the carrier 2, 3 has a horizontal plane.
  • the adjusting piece 6, 7 is provided with a slot 11 at its end resting on the underside of the base plate 1. This is arranged in the longitudinal direction of the roller skate.
  • a clamping element 8 engages in the slot 11. In its simplest form, as shown as a screw, this can also be in the form of a quick-release element known per se. This makes it possible to move the adjusting piece 6, 7 continuously in the longitudinal direction along the base plate 1 of the roller skate.
  • the surface 12 of the adjusting piece 6, 7 which lies on the plane 10 of the free support 2, 3 and runs parallel to the plane 10 has a different width in the longitudinal direction of the base plate 1. It can be designed as an isosceles triangle, the base of which is approximately is parallel to the axis 4 of the rollers 5 and the tip of which is arranged approximately on a line running in the middle between the paired rollers 5. This results in an even left swing on both sides.
  • the triangle is preferably formed at an acute angle.
  • the widest point corresponds approximately to the width of the plane 10 (FIG. 3).
  • the width of the surface 12 is smaller than that of the plane 10.
  • the support can be punctiform at the narrowest point. This is achieved by a semicircular design of the surface 12 (Fig. 2).
  • An expedient form of the adjusting piece 6, 7 is a Z-shaped double angle, the upper leg provided with the slot 11 on the base body 1 extending to the center of the roller skate and thus being easily accessible from below.
  • the desired hardness can be continuously adjusted.
  • the surfaces 12 of the adjustment pieces 6, 7 can assume a different position relative to the free support 2, 3.
  • the adjusting pieces 6, 7 can have the same or different configuration of the surface 12 from one another.
  • men's roller skates have a wider area than children's roller skates, which are provided with a very acute-angled design, while in the case of women's roller skates the areas 12 of the adjusting pieces 6, 7 are generally between the two in width.
  • the solution according to the invention can also be used with other roller sports equipment, such as roller boards.
