Definitions

  • the present invention relates to a role, in particular for sports or leisure equipment such as inline skates, roller skates, skateboards, rollerboards or the like. Although applicable to any role, the present invention and the problem underlying it in terms of inline skates are explained in more detail.
  • inline skate rollers from a rim-like inner ring, which has centrally a bore for receiving an associated axis.
  • the inner ring has a plurality of rigid spokes extending in the border of the bore to the outer edge of the inner ring.
  • An elastic race is inextricably linked to the outer surface of the inner ring, that is, the inner ring forms a unit with the outer ring.
  • the inner ring is generally made of a plastic and is encased by a rubber as a raceway.
  • the material of the race is generally composed of a rubber / plastic mixture, wherein the race has a predetermined elasticity such that when rolling on the roadway a spring and shock absorbing effect is achieved.
  • the present invention has for its object to provide an aforementioned roller, which has both good damping properties and a race with a low wear.
  • the idea underlying the present invention is to equip the spokes of the rim-like inner ring of the roller in each case as or with a resilient device for shock absorption by defined displacement of the bore and the race relative to each other. Due to the formation of the spokes as or with resilient devices, a defined displacement of the bore and the race is accomplished in shock relative to each other such that, for example, shocks through an uneven track or obstacles located on the track, such as small stones or the like, not only by the elastic properties of the race, but are essentially damped by the resilient means of the spokes. This ensures a variable and extremely effective shock absorption, without the choice of material for the raceway any Limited. The user advantageously experiences a noticeably better damping and consequently a greater driving comfort when driving on bumpy and uneven road surfaces.
  • the material for the race can also be advantageously selected independently of the degree of damping for optimum road grip. Since the damping characteristic in the roller according to the invention is essentially carried by the spokes, the material of the race can be better tuned to the ride characteristics and optimized without increased wear due to otherwise be provided damping properties must be taken into account.
  • a weight-optimized adaptation of the respective role to the respective user is possible by suitable material properties and a suitable shaping of the spokes or the resilient devices.
  • the roller according to the invention thus provides an increased sporty effect by smoothly sliding on the rollers, whereby shocks and vibrations are better absorbed on uneven and bumpy road surfaces. This advantageously reduces the risk of fatigue and falling.
  • each spoke is formed approximately the same or even identical.
  • each spoke has an approximately S-shaped configuration such that always predetermined first and second sections of two adjacent spokes in the radial direction on a common Are straight, that is, that the spokes S-shaped do not extend in the radial direction from the bore to the race, but are arranged inclined relative to the radial direction uniformly to a predetermined side.
  • predetermined sections of the spokes can each serve as defined abutment sections for limiting the maximum deformation of the respective associated spokes in the event of deformations occurring for shock absorption.
  • the spring-elastic devices or spokes are each assigned at least one limiting device for a defined limitation of the maximum spring action of the spring-elastic spokes.
  • limiting devices for example in the form of inserts, are also conceivable.
  • Such inserts may be either fixedly or releasably connected to the respective portions of the spokes such that the adjacent deformed spokes or portions thereof are in abutment with the inserts in the event of shock absorption to limit maximum deformation. This ensures that the inserts can be selected depending on, for example, the weight of the user and thus limit the maximum deformation of the spokes predefined defined. Consequently, damage to the spokes can be prevented by excessive deformation.
  • the elastic characteristic of the spokes is preferably defined by the selection of the material of the spokes, the selection of the shape of the spokes and / or the hardness and / or shape of the limiting devices. Consequently, advantageously, the resilient properties of the spokes through corresponding selection of these parameters can be optimized for the respective user and / or the respective floor covering. As a result, without an increase in the wear of the race improved damping properties of the role when driving on, for example, uneven ground levels guaranteed.
  • the inserts are exchangeable.
  • the inserts can be attached to predetermined portions of the spokes or pushed into corresponding recesses and thus easily replaced by inserts with different degrees of hardness.
  • the regions between the individual spokes for forming the limiting devices can also be filled at least partially with a material, for example with an elastomer, with a predetermined degree of hardness. It can therefore co-determined by appropriate selection of the filling material, the damping properties of the role and the maximum deformation effect of the spokes are limited in a predetermined manner.
  • each memory of a suitable plastic or metal is formed such that the above-described elastic properties on the one hand and on the other hand, a predetermined stable rolling behavior on the road at the corresponding force is ensured.
  • the damping properties of the roller are determined according to the present invention mainly by the configuration of the hub, in particular by the configuration of the spokes or the intended inserts, so that the raceway has to take no or reduced damping properties and can be formed of a more wear-resistant material.
  • the raceway is preferably made of a plastic such as rubber or hard plastic and optionally provided with embedded reinforcements such as particles, fibers, fabric and the like.
  • each roller 1 consists of a rim-like inner ring 2 and a hub 2 and a fixedly connected to the hub 2 raceway third
  • the hub 2 consists for example of a base part 4, which has a bore 5 in the center, which serves to receive a corresponding axis.
  • a peripheral ring 6 is provided, which comprises a plurality of recesses 7.
  • spokes 8 are arranged according to the present embodiment.
  • the spokes 8 each have a curved shape, for example as in the Fig. 1 to 4 represented an approximately S-shaped configuration, wherein the connection point of a spoke is provided on the base part 4 relative to the attachment point of the spoke 8 on the peripheral ring offset in each case in the circumferential direction, that is, the two connection points seen in the radial direction not on the same line, as in conventional roles normally the case.
  • the spokes 8 are preferably all identically curved in such a way that they have a resilient characteristic, preferably substantially in the radial direction. Like from the Fig. 1 to 4 can be seen, the spokes 8 are preferably curved such that each seen a first portion 9 of a spoke 8 in the radial direction is on the same line as a correspondingly assigned second portion 10 of a corresponding adjacent spoke 8, preferably a vorlaufilenden in the direction of the spoke 8. Die preferred direction of circulation is in Fig. 1 shown schematically by the arrow.
  • the spokes are for example made of a suitable plastic or a suitable metal such that certain elastic properties are ensured by the spoke system.
  • the individual parameters of the spokes for achieving predetermined elastic properties can be modified as desired, since parameters such as the number, the geometrical configuration, the thickness, the material, the relative arrangement of the spokes 8, the elastic properties determine the hub 2.
  • the damping property of the hub 2 or the roller 1 can be determined and advantageously adapted and optimized to the respective user and / or to the respective floor covering.
  • each second portion 10 of a spoke 8 forms a kind of limiting device or a limiting section for a system of the first section of each subsequent in the direction of rotation spoke 8. This ensures that a defined Deformation of the individual spokes occurs up to a predetermined contact point. Consequently, damage to the spokes 8 and the roller 1 as a whole can be effectively prevented.
  • connection sections of each spoke 8 are to be designed both on the base part 4 and on the peripheral ring 6 in accordance with the respective occurring forces in such a way that damage to the individual spokes 8 does not occur in the occurring impacts or forces ,
  • the race 3 consists for example of a plastic such as rubber or hard plastic and may optionally be provided with embedded reinforcements such as particles, fibers, fabric or the like.
  • the raceway 3 is cast on the outer shell of the hub 2 such that the material of the raceway 3 fills the recesses 7 of the peripheral ring 6 of the hub 2 for a stable connection of the hub 2 and raceway 3. It is obvious to a person skilled in the art that a connection of race 3 to hub 2 can also take place in other ways or that the hub 2 and the race 3 can be formed integrally with one another.
  • the raceway 3 can be formed from a matched to the corresponding flooring material such that the wear of the raceway 3 is reduced and the ride comfort and the life of the roller can be increased.
  • the hub has a resilient means in that the shape of the spokes 8 and the material of the spokes 8 is selected accordingly.
  • a resilient means in that the shape of the spokes 8 and the material of the spokes 8 is selected accordingly.
  • other resilient devices are conceivable, which ensure a relative displacement of race 3 and 5 hole for shock absorption or damping at impact influences.
  • the in the Fig. 1 to 4 illustrated embodiment is particularly advantageous because of the geometric configuration of the individual spokes 8 both a resilient property as well as a defined limitation of the deformation is created by conditioning corresponding to associated sections each two adjacent spokes.
  • other limiting devices are conceivable.
  • Fig. 5 illustrates a roll 1 according to a second preferred embodiment of the present invention.
  • the roll 1 according to the second embodiment has in the open areas between the spokes 8 a filling material 11, which consists for example of a suitable elastomer.
  • the filler 11 completely or only partially the areas between the individual Fill spokes 8.
  • the filling material 11 can determine the spring-elastic properties of the spokes 8 by way of attachment, type of material selection or the like and limit the maximum elastic deformation of the individual spokes 8 in a predetermined manner.
  • a roller 1 according to a third preferred embodiment of the present invention is illustrated.
  • inserts 12 are provided as limiting devices in the first sections 9 of the respective spokes 8.
  • the inserts 12 are made of a suitable material, such as an elastomer or the like, and can be pressed into recesses provided in the region of the second portions 10 of each spoke 8, inserted or pushed from the side.
  • the inserts 12 may all be formed as individual inserts or may also be formed as a contiguous insert ring which can be plugged onto the spokes 8 accordingly.
  • the inserts 12 also serve as limiting means for limiting the maximum deformation of the spokes 8 in a shock absorbing operation such that the maximum deformation of the spokes 8 is defined limited.
