Definitions

  • the invention relates to a swiveling device for a skateboard, wherein the swiveling device comprises a base part, which can be attached below a skateboard deck of the skateboard, and a pivoting part, to which a first, preferably a front, driving axis of the skateboard can be arranged.
  • Such swivel devices are known from the prior art.
  • the pivoting movement of the pivoting part is sprung according to the prior art by means of a tension or compression spring.
  • Such pivoting devices have the serious disadvantage that the spring rate of the built-in spring can not be set or can only be set with great difficulty in order to adjust and adjust the handling behavior of the skateboard according to the needs of the skater.
  • a pivoting device for a skateboard wherein the pivoting device a below a skateboard deck of the skateboard attachable base part and a pivot member to which a first axis of the Skateboards is arranged, comprises, wherein the pivoting part about a pivot axis relative to the base part is pivotable and a first end of a torsion spring element with the base part and a second end of the torsion spring element with the pivoting part is at least in operative contact, wherein a value of a force and / or a Pivoting angle with respect to a pivoting of the pivoting member relative to the base part of a value of a variable by a change in position of the first and / or the second end of the torsion spring element spring rate of the torsion spring element is dependent.
  • the spring rate of the torsion spring element can also be changed by a change of an attack point of the force on the first and / or the second end of the torsion spring element.
  • the corresponding engaging lever changes, which consequently changes the torque and thus also changes the spring rate of the torsion spring element.
  • swivel angle is to be understood here as meaning the angle which the swivel part occupies after swiveling relative to the base part.
  • the angle between a longitudinal extent of the pivoting part and a longitudinal extent of the base part is arranged. The larger the swing angle, the farther the swing member has been pivoted relative to the base member in a circumferential direction.
  • the force is the force that is needed to pivot the pivoting member relative to the base part. If, for example, the spring rate has been increased, then more force is needed overall to deflect the pivoting part by the same angle of rotation.
  • the pivot axis is particularly preferably a real pivot axis.
  • the pivoting part is mounted pivotably about at least two pivot axes, for example by means of a pivoting head, whereby a three-dimensional pivotal movement of the pivoting part is possible.
  • the torsion spring element is arranged at least partially around the pivot axis, wherein a longitudinal extension of the torsion spring element coincides with a longitudinal extent of the pivot axis.
  • the space requirement can be reduced, so that overall the pivoting device can be built smaller and more compact in size.
  • the torsion spring element is a leg spring having a first and a second leg, wherein the first leg corresponds to the first end of the torsion spring element and the second leg to the second end of the torsion spring element.
  • a leg spring can be arranged particularly easily and simply around the pivot axis. Furthermore, a leg spring is advantageous in that the spring rate can be changed particularly simply or advantageously by changing the position of the first and second legs.

  • first Federendeneinhuckonne and at least two second Federendeneinhlidonne are provided which are each formed as a recess and the first and second ends of the torsion spring element itself extend in a longitudinal direction of the torsion spring member or at an angle to the longitudinal direction and the first end engages in a first Federendeneinhfitung and the second end in a second Federendeneinhfitung, wherein by a transfer of the first end and / or the second end in one of the respective end corresponding spring input mounting the spring rate of the torsion spring element is variable.
  • both the base part and the pivoting part have recesses, which may be configured, for example, as bores or the like.
  • the recesses extend in a height direction and in particular perpendicular to a longitudinal extension of the skateboard or at an angle to the height direction and / or at an angle to the longitudinal extent of the skateboard.
  • the longitudinal extent of the skateboard coincides with the longitudinal extent of the base part.

  • the first end of the torsion spring element is transferred from a recess of the base part into another recess of the base part, whereby the spring rate of the torsion spring element is variable.
  • the second end of the torsion spring element can be correspondingly transferred from a recess of the pivoting part into another recess in the base part, whereby a change in the spring rate is likewise accompanied.
  • the recesses of the base part and of the pivoting part are arranged in a circumferential direction about the pivot axis.
  • the recesses are arranged such that the ends of the torsion spring element are arranged at a positional adjustment of the ends on a circumferential direction of the torsion spring element, since the torsion spring ends are not changed about the pivot axis per se in position, but about a fictitious pivot axis which does not the pivot axis of the pivoting part coincides.
