Definitions

  • the invention relates to a roller skate, in particular roller skate, with at least one front and at least one rear roller provided with bearings, a roller carrier, a shoe attachment and a damping device provided between the shoe attachment and the bearings.
  • the US 5,575,489 shows an inline skate with a damping device.
  • the damping device has a triangular body attached to the underside of the shoe with an opening. From the triangular body go out two beam-like projections, which extend in a substantially V-shaped forward or backward. The rollers are attached to the extensions. In a vertical load, the ends of the extensions are pushed upwards and the triangular body deformed.
  • the US 4,993,725 discloses a skate with a damping device.
  • the damping device absorbs a landing after a jump, which prevents sports injuries.
  • one or more substantially C-shaped, elastic supports are provided, which establish the connection between the runners and the shoe.
  • a C-shaped section is attached to the front and at the rear end of the skate.
  • the FR 2814683 discloses a rollschuch with arcuate damping elements, which should have a minimum height.
  • the object of the invention is to provide an in-line roller skate which has improved cushioning properties and is simple and inexpensive to manufacture.
  • the damping device has only one running in the shoe longitudinal direction, arcuate damping element or more seen in the shoe longitudinal direction side by side, arcuate damping elements, which is arranged in the side view of the skate centrally on the skate / are, where deforms the arcuate damping element elastically under the action of a vertical force taking another arch shape becomes.
  • the bow height is for example at least 50 mm, preferably at least 65 mm. This height ensures a large suspension travel, which significantly improves ride comfort.
  • the height can also be for example 20 cm.
  • the at least one central and very large arcuate damping element is uniformly deformed with a vertical force, ie jerky shocks that would worsen the ride comfort are well damped.
  • the damping device improves the driving feeling.
  • the damping element also has a spring action, so that energy is given back to the driver when repelled.
  • jumps, bumps, etc. are compensated by the damping device over a large damping and suspension travel, which reduces the risk of injury and increases the load capacity of the skate.
  • a higher speed can be achieved with the roller skate according to the invention.
  • the at least one damping element is arranged centrally on the skate in order to be able to better absorb and forward the forces and to enable large damping paths.
  • Central here means that the damping element is arranged substantially centrally when looking at the entire roller skate and the rollers.
  • the damping element is therefore not provided in the edge or outer region of the roller skate, as for example in the US 4,993,725 shown, resilient portion of the skate is.
  • the damping element assumes a curved shape with a larger radius during deformation, i.
  • the ends are not compressed, but bent, which provides a soft cushioning.
  • the damping element is displaceable in at least one end in the horizontal direction and is not rigidly fastened, for example, at its ends.
  • the damping element has a chord length which corresponds at least approximately to the length of the attached shoe.
  • the force acting on the damping element, transmitted from the shoe ends vertical force distributed evenly and on a sufficiently large area.
  • the damping element is optimally large in order to achieve the high damping paths.
  • the damping element has a chord length corresponding to at least 80% of the center distance between the foremost and rearmost rollers to ensure that the introduced vertical force is distributed over a sufficiently large area.
  • the damping element should in particular be a continuously curved arc. About the initial curvature, so the curvature, which is present without the action of a vertical force, the damping and the spring characteristic can be changed. A uniform curvature over the entire length of the damping element ensures a uniform application of force and power distribution.
  • the damping element is preferably a leaf spring-like body, i. a body whose thickness is substantially smaller than its width (preferably by a factor of 2).
  • the width and the thickness of the leaf spring-like body and thus the spring property of the damping element can be varied over the arc length.
  • the maximum width of the leaf-spring-like body should be hand width, otherwise the damping element of the left skate and that of the right skate abut each other in a parallel driving and possibly interfere, hinder and / or get caught.
  • the damping element is a one-piece body, whereby production and assembly of the skate are simplified, resulting in cost savings. Furthermore, the stability is very good.
  • a plurality of laterally interconnected damping elements are provided.
  • a web for example, connect the damping elements together.
  • the damping element has bow ends that lie substantially in a common horizontal plane. This is substantially parallel to the plane of the shoe attachment or the shoe sole. The force distribution is thus uniform.
  • the midpoint of the arch (more specifically, the area around the midpoint) is in side view on an area between the ball of the foot and the shoe center. If the ball of the foot is at the center of the arch, it is most likely to tilt backward, as the center of gravity is offset. However, if the shoe center is at the center of the arch, tilting is the least likely.
  • the midpoint of the arch (more specifically, the area around the midpoint) in side view is substantially at the shoe center or below the center of gravity of the body, making tilting forward or backward more unlikely.
  • a fastening device for holding the shoe may be provided.
  • the force is introduced into the damping element. Due to the central attachment, a uniform force is applied.
  • a fastening device for holding the shoe is provided in the region of an arc end. The second end of the sheet is then connected to the roll carrier.
  • fastening points are provided, which are provided at the transition from the arc center to the bow ends, i. the bow center has no attachment points. It can be provided two or more attachment points.
  • connections between the damping element and the adjacent part are preferably designed to be movable in the longitudinal direction in order to allow free deformation of the damping element.
  • the vertical forces are transmitted exclusively over the ends of the damping element.
  • the damping element is therefore not attached over a large area to the shoe attachment or the roller carrier, which would reduce the available for the suspension and damping, non-clamped portion of the arc.
  • the contact surface for the attachment between the damping element and the shoe attachment or between the damping element and the roller carrier is as short as possible, since the flexibility of the damping element is limited for this arc section and with an increase in the contact surface is accompanied by a reduction of the damping and spring potential.
  • the entire vertical force between the shoe attachment and the bearings via the damping element transfer. So there are no additional connections or dampers between the shoe attachment and the camps provided.
  • the bow ends are down and form the roller-side end of the damping element.
  • bearing attachments are mounted for the rollers, which makes the structure of the skate easy and reduces its weight. During compression thus increases the roll distance between the foremost and rearmost role. Furthermore, no guide for the ends of the damping element is necessary.
  • the bearing fixtures can be attached to the bow end.
  • the size of the attached rolls can be changed or the rolls exchanged. The bigger the rollers, the higher the speeds can be achieved.
  • a roller skate can be adapted individually to the skill of a user or the road surface quality. Also, the later mentioned replacement of the damping element can be so simplified.
  • the bow ends are upwards, and at least one end of the bow is displaceable.
  • the radius of the damping element can increase at an acting vertical force.
  • the displaceable end of the sheet is guided in a guide.

  • the shoe attachment is preferably coupled directly to the guide, so that no additional parts must be mounted on the guide.
  • the bow ends are accommodated in a displaceable pivot bearing.
  • Such a construction allows the arcuate Damping elements elastically deform in a vertical force to another sheet shape.
  • the damping element is non-destructively releasably integrated on the skate.
  • the damping element can be replaced so quickly and easily.
  • the skate can only have two rollers and thus run smoothly.
  • the damping device preferably also forms the roller carrier.
  • An additional roll carrier eliminates this, which simplifies assembly and reduces weight. In addition, the height is thereby reduced.
  • a spring element connecting the bow ends is provided.
  • the spring element which is for example an elastic rubber band and is preferably made of carbon or glass fibers, is tensioned in the event of a vertical force acting on the rollers.
  • the spring element is optimally biased in the optimal case at first. This prevents a "jerk" during compression.
  • the spring element exerts a restoring force that supports the damping element to return the sheet to the starting position.
  • the shoe attachment for releasably attaching shoes is formed on the skate.
  • street shoes, sneakers, soft boots, hard boots or even ski boots can be attached to the roller skate.
  • the shoe can be fixed with buckles and / or loops, for example.
