are screwable. As the different types of vehicles are also designed differently and differently have dimensioned i-bolts, it is necessary to a variety of specially trained rim bolts with mounting screw mounting holes in stock to hold - which does not contribute to high profitability.

With the adapter, however, a device is created that makes it possible. Components to be fastened to existing and common screws by means of fastening screws- .. The adapter is placed on the head of the existing screw and by tightening the nut, the form grippers are pressed against the screw head by moving the sleeve downwards and the adapter is pressed onto the screw head held, wherein the adapter is secured against being pulled off from the screw head, as the mold grip spannzangenart \ g surround the screw head. Only when the nut of the adapter is loosened is the pressure exerted by the form grippers on the screw head released, so that the adapter can then be pulled off the screw head. The adapter can be placed on all common screw heads if the dimensions of the adapter are selected accordingly. Since all known rim bolts for vehicle wheels are in a dimensional range with slight deviations up or down, there is the possibility that, for example, only three sizes can be used to cover all known rim bolts or bolts. Because the nut of the adapter is provided with a hexagon on the outside, the nut can be operated with known and available tools. The cap-shaped component of the adapter has an interior space and a cross-sectional shape that enables it to be placed on conventional visual screw heads, the cross-section of the cap-shaped component also being hexagonal, which then also enables the adapter

Put on screw heads / the one circular Have cross-section. Also an adapter with a component whose cap-shaped section is circular Has cross-section, is attachable to the head of a hexagon screw, as in all cases when tightening the nut, the form grippers are pressed against the screw head, which grip this like a collet. These Effect of the form gripper is achieved in that the outer conical Wändäbschhitte in the area of Downward movement of the sleeve when screwing in the flutter be pressed towards the screw head with the The result is that the form grippers are pressed against the screw head. The fastening of components of all kinds, such as e.g. the hub of an anti-skid device described above takes place by means of a fastening screw, which is screwed into the longitudinal bore of the component of the adapter after the nut on this adapter component has been screwed on so that the adapter is held on the screw head.

According to FIG. 4, the receiving part 52 of the hub 50 has the adapter disk 300 a number of hub fastening screw receiving bores lying on a circular line around the center point of the adapter disk 300 340 with the through bores 51 of the receiving part 52 of the hub 50 are aligned, the number of through-holes being 340 corresponds to the number of through bores 51 in the receiving part 52. These hub mounting screw receiving holes 340 are equally spaced from one another.

To the anti-skid device 10 on the rim 11 one To be able to attach the vehicle wheel, it is necessary that the hub 50 of the anti-skid device to the rim is connected. This is done using rim bolts, However, which must have a special design to the actual locking screws 85 for the Hub 50 to be able to accommodate. For this reason, it is necessary to use rim bolts that have a special design in order to be able to fasten the hub 50. For this purpose are mostly special trained rim bolts are used and, due to the large number of types of motor vehicles, it is also necessary that a large number of wheel rim bolts are then available and kept in stock to the anti-skid device for the different car models to be able to use.

By using an adapter 400, as shown in FIGS. 10 to 15, it is possible to to use and distribute existing rim bolts of the adapter to be able to fasten the securing screws, which are used to secure the hub 50. This adapter is designed in such a way that the screw head An adapter placed on a rim screw establishes the connection between the rim screw and the locking screw

85 manufactures for the hub. Because the adapter 400 fits for the various rim screws. Bolt or Nuts can be used, it is not necessary to have a Manufacture a large number of adapters and keep them in stock, but it is sufficient if, for example, three adapter sizes are available, surprisingly, can with these three adapter sizes are known to all rim bolts Motor vehicle mode I Le are served.

The adapter 400 engages around or engages over the head, such as a hexagon head or the like, a rim screw 18 or a nut or the head of a wheel stud.

The adapter 400 according to FIG. 15 consists of a nut 450, a cap-shaped component 460 and a sleeve 470, The bottom of the nut 450 is provided with a circumferential edge 451; it has a longitudinal perforation 452 and an internal thread indicated at 453 (FIGS. 10 and 11). The longitudinal through-hole 452 is dimensioned so that that the nut 450 can be screwed onto the component 460 of the adapter described in more detail below.

The cap-shaped component 460 consists according to FIG. 12 and 13 from a molded body with an upper neck-like section 462 drawn in, which has a central longitudinal through-hole 463 is provided, which has an internal thread indicated at 464. At 462 is an external thread indicated. The diameter and dimensions of this neck-like portion 462 are dimensioned so that the Nut 450 shown in FIGS. 10 and 11 can be screwed onto the neck-like section 462 of the component 460. The inner through hole 463 of the component 460 is used to accommodate a not shown in the drawing Fastening or locking screw to «fasten a part of the device or a hub 50 for fastening the anti-skid device described above.

The neck-like section 462 of the component 460 goes under Formation of a circumferential shoulder 461 in a cap-shaped section, whose wall surface 466 with a Number of longitudinal slots 467 is provided so that between two longitudinal slots an arm-like shape gripper 469 is formed is. These form grippers 469 have a certain mobility or elasticity due to the used Material and can be, as described in more detail below, in the direction of arrow Z after tightening the nut 450 and attached sleeve 470 (Fig. 14) move so the adapter after placing its component 460 on a hexagon screw, not shown in the drawing held securely and so attached to the head of the hexagon screw that sin removal or automatic Solving is not possible.

After the sleeve 470 has been placed on the component 460, as shown in FIG. 5 , the nut 450 is screwed onto the neck-like section 462 of the component 460, the peripheral edge 451 of the nut 450 on the upper peripheral edge 471 of the sleeve 470 rests. By tightening, ie further screwing in the nut 450, the sleeve 470 is moved downward in the direction Z of the arrow, with the result that, due to the conical configuration of the lower edge areas, the form grippers 469 are pressed in the direction of the arrow Z against the surfaces of the hexagon screw, to which the adapter is to be attached. In order to achieve this, the form grippers 469 are provided in their lower edge regions with a circumferential wall section 468 that widens conically outward. The lower circumferential edge 472 of the attached sleeve 470 then comes to rest against the inclined wall surface 468 of the component 460 and with a further vertical downward movement of the sleeve 470, the form gripper 469 is then pressed against the hexagon head of a screw due to the pressure that occurs. The surrounding investment edge

472 of the sleeve 470 can, as shown in FIG. 12, be designed beveled outwards to ensure proper sliding of the lower circumferential edge of the sleeve 470 on the conical wall surface 468 of the component 460 when the sleeve 470 when tightening the Nut 450 is moved in the direction of arrow Z downwards.

Because the sleeve 470 is annular, the wall surface of the sleeve provides a counterpressure surface when pushed onto the form gripper 469, so that the wall surface of the sleeve 470 the pressure of the form gripper 469 can not evade, but the form gripper in the direction of the arrows Z to press against the hexagon head be moved.

The cap-shaped portion of the component 460 can, be circular as shown in Fig. 13, but there is also the possibility of a cross-sectional configuration to choose that corresponds to the shape of a hexagonal head. The circular shape of the cross section of the molded body 460 has the advantage that the component 460 is not only can be placed on screws with a hexagonal head, but also on heads with a different shape, surprisingly is that due to the design of the adapter 400 this on any head shape and in particular on hexagonal heads so firmly seated that pulling or loosening the adapter from the hexagon head of a screw not possible."

The individual parts of the adapter 400 are made of metal Materials. The mobility or the possibility of easy turning and springing back into the starting position the shape gripper 469 is achieved due to a suitable choice of material. ALs materials can be suitable Types of steel, especially steel with resilient elastic looks Properties, find use. However, look for others suitable materials can be used.
