Definitions

  • the invention relates to an axle assembly for a skateboard according to the preamble of claim 1 and a skateboard formed therewith.
  • Skateboard axles are usually designed so that an inclination of the "skateboard deck", ie the footprint of the skateboard, about its longitudinal axis leads to a steering deflection of the Radachspaares.
  • U.S. Patent 1,935,187 discloses a skate having a serving as an axle support element on which rests the base plate of the skate.
  • a fork structure is mounted rotatably about an axis on the support element, which extends obliquely to the horizontal, and has two prongs, in which the axis is mounted for a pair of rollers.
  • a stop plate connected to the support member is provided, and a pair of compression springs which surround the roller axle and press on different sides against the stopper plate and are arranged between the latter and the prongs of the fork structure.
  • Such axle as it is disclosed here for use on a roller skate, but in the same way could find application for a skateboard, can be tilted about the support member and the fork structure connecting axis of rotation and against the spring forces.
  • This axis of rotation must have an angle relative to the longitudinal axis of the base plate of the skate (or of a skateboard deck) in order to cause a steering movement of the skate (or skateboard) axis with the inclination movement of the base plate (or the skateboard deck).
  • axle structure has to be completely broken down into numerous individual parts, in order to achieve individual components or to remove for replacement.
  • Skateboards are increasingly being used on unpaved surfaces and dubbed "mountainboards” or “all-terrain boards”. Such special skateboards are operated, for example, with kite-kites on the beach. The requirements for the axle unit are very high with these extensions of the sport. In these areas of skateboarding therefore mainly spring-supported axle units are used. Two compression springs or tension springs support the wheel axle laterally in this construction.
  • the publication US 2003/057670 A1 shows such an axle unit with tension springs.
  • a resilient, with respect to the forces adjustable structure for skateboards is disclosed, the staple bodies each having an upper and a lower retaining clip, which are rotatably interconnected, and a spring mechanism comprises, wherein the upper relative to the lower retaining clip is pivotable.
  • the spring mechanism comprises in addition to the already mentioned tension springs a resilient body which rests on the lower retaining clip and by two retaining elements, which are passed through the upper holding element by means of a threaded threaded portion, is fixed.
  • the springs can be implemented on such constructions on the one hand, so that the lever ratios and ultimately the balance of forces on the axle change.
  • the retaining elements can be stronger or less screwed in the direction of the resilient body, so that its bias and thus the spring action on the axis can be changed. In this way, the skateboard axle can be adapted to individual driver needs.
  • a skateboard comprising a braking element that acts on a wheel unit, wherein the braking element is reset by a spring.
  • a steering function does not have this spring.
  • a kiteboard comprising a pendulum suspended axle, which is supported by two spring elements, wherein the axle is mounted above the board.
  • a generic axle assembly for a skateboard comprising an axle module, which has a wheel axle, at least one concentrically arranged with the wheel axle spring element, a concentric support structure for receiving at least the components wheel axle and spring element and at least one fastening means for holding the wheel axle in the support structure wherein the received components are arranged in the concentric support structure such that by releasing the at least one attachment means for holding the wheel axle in the support structure, the accommodated components are directly removable from the concentric support structure.
  • the invention is therefore based on the technical problem of providing an improved axle arrangement for a skateboard and a skateboard equipped with a corresponding axle arrangement, which can be maintained particularly easily and flexibly adjusted and satisfy as many driver preferences as possible for different purposes. Adapting to individual driver preferences should be as easy as possible. Another technical problem is to achieve the simplest possible adjustability of a different steering behavior of the skateboard.
  • an axle assembly is proposed for a skateboard comprising an axle module, which has a wheel axle, at least one concentrically arranged with the wheel axle spring element, a concentric support structure for receiving at least the components wheel axle and spring element and at least one fastening means for holding the wheel axle in the support structure, wherein the received components are arranged in the concentric support structure such that by releasing the at least one fastening means for holding the wheel axle in the support structure, the recorded components of the concentric support structure are directly removed.
  • a “fastening means" for holding the wheel axle is understood to be an element which can absorb forces to a sufficient extent and is suitable for keeping the axle in its concentric supporting structure during its intended use, for example while driving, for example a wheel nut ,
  • the at least one fastening means is formed concentrically to the wheel axle. If a plurality of fastening means are provided, it is further preferable to release only one of them in order to be able to remove the recorded components directly from the concentric support structure.
  • intermediate is to be understood that no further attachment means, which does not serve to hold the wheel axle in the support structure, must be solved in order to remove the recorded components from the concentric support structure can.
  • the concentric support structure is at least partially formed as a sleeve. This is primarily the encapsulation of the essential mechanically effective elements of the axle module for protection against contamination and against the unwanted influence of external forces.
  • the concentric support structure designed as a sleeve is then closed at its open ends by means of sealing plugs.
  • the wheel axle can then be passed along the longitudinal axis of the axle assembly through the sleeve.
  • the sealing plug of the sleeve are provided for this purpose along this longitudinal axis in each case with a bore, so that the wheel axle can pass through them accurately.
  • the partially formed as a sleeve concentric support structure also offers the further advantage that the components located in the support structure, for example, the or the spring element (s) are held by the sleeve and not exclusively from the wheel axle.
  • these components correspond, for example with respect to their inner diameter, precisely to the outer diameter of the wheel axle in order to be held, but larger inner diameters can also be selected.

  • a bolt is provided for fastening the axle module on the mounting shoe and its pivotable mounting.
  • the mounting shoe preferably fixes the bolt so that its longitudinal axis is at a slightly acute angle to the longitudinal axis of the skateboard.
  • the axle module together with the wheel axle performs a steering movement when the skateboard deck is tilted about its longitudinal axis.

  • the heart of the axle arrangement is the axle module. It takes on the essential mechanically effective parts of the axle assembly in itself, in particular one or more spring elements and at least a portion of the wheel axle. All received elements preferably form a channel along the longitudinal axis of the axle arrangement, so that the wheel axle can be guided along this longitudinal axis through the axle module.
  • the axle assembly also has on its outside a receptacle for a bolt around which it can be tilted.
  • the axle module preferably has two further openings, through which possibly existing carriers of a corresponding component can reach and, in the event of a tilting of the axle module, load the (or the) spring element (s) accommodated in the latter axially in the direction of the longitudinal axis of the axle module relieve.

  • the axle assembly according to the invention is due to the advantages described preferably for use in the off-road area, i. for driving on unpaved ground.
  • applications such as mountainboarding (i.e., skateboarding in mountainous terrain, in both "downhill” and “freestyle” modes), or kiteboarding (i.e., skateboarding with the aid of a towing kite) are envisioned.
  • the axle assembly according to the invention can be used advantageously for conventional skateboard applications (for example on a fixed surface or in equipment designed specifically for skateboarding).

  • the axle module has at least one tube sleeve which is arranged concentrically around the wheel axle. It is preferred to refer to exposed, i. Not enclosed by the concentric support structure areas of the wheel axle each pushed a tube sleeve whose inner diameter corresponds to the outer diameter of the wheel axle. If skateboard wheels of commercial type (ie with ball bearings) are now mounted on the ends of the wheel axle, the inner ball bearing rings of the wheels preferably press the tubular sleeves against the concentric support structure (or the sealing plugs preferably arranged there), thus tensioning the (or the) Spring element (s) before and secure the wheel axle against lateral displacement. Preferably, then, after the disassembly of only one wheel, all the components of the axle module can be separated directly from one another.
  • At least two tube sleeves are provided, which have a different length.
  • the wheel axle can be positioned off-center, which ultimately leads to an increased contact pressure of the front or Backsidezier (ie the lateral position of the driver on the skateboard relative to his posture front or rear side wheels) to the ground.
  • This setting can z. B. facilitate upwind when a skateboard with a towing kite (kite) is operated.
  • the entire axle assembly is preferably designed in a modular design, i.
  • Axle module and mounting shoe are each designed as prefabricated, individually mountable modules that can be connected together in only one further step.
  • the axle module which is preferably designed as an at least partially tubular sleeve-like element, forms a first subassembly which preferably receives all of the components which are mechanically effective on it.
  • the axle module is penetrated along its longitudinal axis by the wheel axle. This construction arranges the essential components centrally to each other.
  • the mounting shoe which serves to fasten the axle module on the skateboard deck, forms a second assembly, wherein the mounting shoe can be shaped differently thanks to the preferred modular design of the axle assembly and thus allows attaching the skateboard axle at various locations of a skateboard deck or skateboard decks of different types.
  • the modular construction causes the first assembly and the second assembly to be minimal in shape.
  • the mounting shoe and the axle assembly can thus be performed almost arbitrarily, provided that their interface, namely the pivotal mounting and the driver element or the fastening means provided on the axle module are mutually compatible. If the various modules are to be separated from each other for individual purposes, only a few central fasteners must be solved.

  • the angle formed by the curved shape of the skateboard deck relative to its longitudinal axis must be constructively compensated during the assembly of the axle assembly in order to still be able to achieve a satisfactory steering effect.
  • axle arrangements with a special mounting shoe necessary to compensate for the curvature of the skateboard decks can be employed.
  • This compensation is achieved by employing a mounting shoe which has particularly projecting limbs inclined with respect to its base, the particularly pronounced inclination by the angle ⁇ compensating for the negative angle caused by the curvature of the skateboard relative to the skateboard longitudinal axis and adding a positive angular component. to ultimately ensure that, as a result, there is an inclination of the axis of rotation of the axle module with respect to the longitudinal axis of the skateboard by the angle ⁇ .
  • a lateral projection is preferably provided as an extension of the base of the mounting shoe.
  • This lateral projection serves better to support the steeply inclined mounting shoe and forces that lead to greater leverage and torques on the mounting shoe due to the greater inclination of the projecting legs.
  • Due to the lateral projection of the mounting shoe preferably receives a cross section which at least partially resembles a tapered stylized letter F.
