Definitions

  • the invention relates to a wheel of the type mentioned in the preamble of claim 1.
  • Such wheels are advantageously used in inline skates that are used as sports equipment and for the Recreational use have become widespread.
  • rollers for roller skates are known, one of two parts have existing hub ring, which is encapsulated with a jacket, the outer Circumferential surface represents the tread. Before joining the two hub parts a ball bearing is used.
  • Each shoe usually has a drive in the four individual wheels are stored. These wheels are rotatable about an axis, the Axis is screwed into the drive.
  • the wheels consist of a wheel body, in the ball bearings are used, which in turn are connected to the axis.
  • the wheel center usually consist of one piece.
  • the invention is based, so the prior art, the task to further develop that the tire exposed to considerable wear easily is interchangeable.
  • Fig. 1 means a wheel, which by means of an axle 2 in frame parts 3 of an inline Skates is arranged.
  • axis 2 consists of two individual parts constructed, namely from a first axle part 4 and a second axle part 5.
  • Both Axle parts 4, 5 have at one of the ends a lenticular collar 6, each of which has an opening 7 in the center.
  • This opening 7 has the shape of a hexagon socket. This enables disassembly and assembly of wheels 1.
  • the first axle part 4 has a bore 8 in an internal thread 9 is cut. Accordingly, the second axis part 5 on the Collar 6 opposite end a pin 10 on the with an external thread 11 is provided. Through the threads 9, 11, the two axle parts 4, 5 are together screwable. In this screwed state, they form axis 2.
  • the wheel 1 consists of two wheel disks 20 and a surrounding and connecting them Wheel tire 21, which in turn is composed of a carrier 22 and a running body 23 is.
  • the carrier 22 has shaped pieces 24 in the recesses 25 of the barrel intervention.
  • the fittings 24 and the recesses 25 are spatially designed so that they Prevent the sound body 23 from slipping on the carrier 22, both in Circumferential direction, d. H. in the running direction, as well as in the lateral direction, i.e. across to Running direction.
  • the shaped pieces 24 are molded directly onto the carrier 22. So he came Carrier 22, for example, a correspondingly designed casting, pressing, injection molding or die casting where metallic materials, e.g. an aluminum alloy, or non-metallic Materials, e.g.
  • a ball bearing 26 is fitted in a suitable central recess in each wheel disk 20.
  • the inner ring of the ball bearing 26 is connected to the axis 2, for example by a narrowly tolerated sliding seat.
  • the ball bearings 26 can advantageously be by means of the axis 2 surrounding spacer sleeve 27 be held at the correct distance. This function can also be taken over by the wheel disks 20.
  • Fig. 2 shows a side view of a wheel disc 20. Its outer boundary 30 forms the Support surface for the wheel tire 21 (Fig. 1).
  • the wheel disc 20 has one in its center Indentation 31, which serves to receive the ball bearing 26 (FIG. 1). The measure of Recess 31 is therefore matched to the outer diameter of the ball bearing 26, wherein a narrowly tolerated sliding seat can also be provided here.
  • the wheel disc 20 has also a number of openings 32 The shape of these openings 32 can vary widely Boundaries are chosen and consideration especially for aesthetic aspects to take. Spokes 33 are simultaneously in the wheel disc 20 through these openings 32 formed, the number of which corresponds to the number of openings. Since the spokes 33 the occurring static and dynamic forces have to be absorbed by them Dimensioning to take due account of these forces. The is reduced accordingly Free space for the design of the openings 32.
  • the material of the wheel disc 20 surrounding the recess 31 forms a wheel hub 34 which in the spokes 33 merges.
  • the material of the Wheel disc 20 up to the outer boundary 30 formed as a rim 35 is by the static and dynamic forces determined. Their assessment is accordingly at the discretion of the Professional.
  • the wheel disks 20 are advantageously produced as cast or die-cast parts, for example made of an aluminum alloy. However, it is also possible to remove the wheel disks 20 highly resilient plastic according to the most suitable manufacturing process manufacture.
  • a through hole 36 In the center of the wheel disc 20 there is a through hole 36, which the Implementation of axis 2 serves. If a spacer sleeve 27 is provided as in Fig. 1, the Bore 36 slightly larger than the outer diameter of the spacer sleeve 27. Is on a Distance sleeve 27 waived, as will be shown, then the bore 36 is slightly larger than the diameter of axis 2.
  • FIG. 3 shows the components of a wheel 1 in the manner of an exploded drawing shown. From the left, these are: the first axle part 5, the ball bearing 26, a wheel disc 20, the wheel tire 21, the same, but opposite to the first wheel disc 20 Wheel disc 20, a ball bearing 26 and the second axle part 4. Designate the same reference numerals same parts in all figures.
  • Each wheel disc 20 has on one side, which in the Mounting state forms the outside, a recess 31 into which the ball bearing 26th can be used.
  • the recess 31 is in depth and diameter exactly to the dimensions of the Ball bearings 26 matched.
  • the wheel disc 20 has one around the central bore Collar 37 on Through this collar 37, the ball bearing 26 is held in the axial direction. This makes the spacer sleeve 27 unnecessary.
  • tooth-like ribs 40 are attached to the wheel disks, which extend along the Alternate inner edge 41 of the wheel disc with indentations 42.
  • Corresponding tooth-like Ribs 43 and depressions 44 are on the edges of the inner diameter of the carrier 22 molded.
  • the ribs 40 fit exactly into the depressions 44 and the ribs 43 into the Indentations 42.
  • the resulting connection when assembling wheel disks 20 and Carrier 22 corresponds to that of the tongue and groove type in wood connections.
  • the wheel 1 according to the invention is designed so that its individual parts by the user can be disassembled and replaced individually.
  • the axle parts 4 and 5 usually belong to the Scope of delivery of the inline skates and can be used again when changing wheels. In principle, this also applies to the ball bearings 26. However, it is possible that the user of the Inline skates buy such ball bearings 26 individually, for example those of a particularly good one Quality if he places high demands on inline skates.
  • wheels 1 In the case of wheels 1 according to the invention, if the wheel tires 21 are used heavily, namely especially the loudspeaker 23, badly worn, so the user is spared the whole Throwing the wheel away. He can buy individual wheel tires 21. To do this, he disassembles axis 2, by using the two axle parts 4 and 5 using Allen keys unscrewed. Then he can the wheel 1 from the frame parts 3 (Fig. 1) remove and disassemble without tools. Using a newly purchased one Wheel tire 21, he can use a wheel disk 20 in each of these from both sides Press ball bearing 26 into the corresponding recesses 31 in the wheel disks 20 and Reinstall the wheel 1 assembled in this way using axle parts 4 and 5.
  • the outer boundary of the loudspeaker 23 advantageously has a radius R that is clear is greater than half the width B of the carrier 22. This ensures that the tread laterally to the direction of rotation of the wheels 1 is less curved. It also means that the Contact area on the road is larger and the specific pressure is smaller. The offers the advantage that the wear on the barrel body 23 is less.
  • the invention also offers the possibility of holding different wheel tires 21, which can be found in Differentiate material and profile of the barrel 23. So can also be different Hardness levels of the barrel body 23 are used. To aesthetic aspects too enough, different colors can be used. Through the invention it is thus possible to adapt the wheels 1 quickly and inexpensively to different needs to adapt, for example to racing skating, hockey, acrobatics etc.
  • the invention also ensures that there is a free space inside a wheel 1 remains that can be used for different purposes.
