Wheel nut wrenches, in particular for trucks

Wheel nut wrenches, in particular for trucks, consisting of a socket wrench on the same axis to the axis of rotation of the socket wrench extending extension two at right angles to the extension of the Socket wrench arranged, offset by 180 ° to each other arranged actuating levers are provided.

In this known cross-wrench, the two operating levers are formed by a rod which the Extension of the socket wrench crosses and permanently connected to the extension at the crossing point is. The two operating levers and the free end of the extension are also used as socket wrenches designed so that the cross wrench can be used for different screw sizes. In particular in trucks, however, the wheel nuts are of such a size and require such a torque, which can only be achieved with relatively long lever arms. This gives the cross key a so large that it can no longer be easily accommodated in the driver's cab of the truck.

The invention is based on the object of a wheel

To create nut wrenches, especially for trucks, of the type explained above, in which such Disadvantages are avoided and can be stored in a space-saving manner.

This object is achieved according to the invention in that the extension of the socket wrench and the two actuating levers can be released via a mounting plate are connected to each other. The wheel nut wrench can thus be assembled for use in a simple manner and can be taken apart again after use, so that it can then be used in a space-saving manner can be kept. The two operating levers and the extension of the plug-in connector are used for storage to loosen from the mounting plate. The two operating levers and the extension of the socket wrench can then be stored parallel to each other, taking up little space.

The fastening plate can have four recesses offset from one another by 90 ° on its outer circumferential surface have in which the extension of the socket wrench and the two operating levers are non-rotatable can be used. Depending on the size of the wheel nuts, the user only needs a socket wrench with the wrench size required for the wheel nuts. The socket wrench can be used for other wheel nuts be exchanged for another socket wrench with the appropriate wrench size. Of course it is It is also possible to use other socket wrenches provided with extensions as the actuating lever. Since the mounting plate has four recesses on its outer shell, it is also possible to use the Side of the mounting plate that corresponds to the plug-in

wrench with extension is opposite, another operating lever or socket wrench with extension to arrange.

The recesses provided in the mounting plate can have a non-circular, preferably hexagonal cross-section and the ends that can be inserted therein Extension and the operating lever can be designed accordingly. This is in a simple manner the Fastening plate rotatably connected to the extension of the socket wrench used, so that with a Turn the mounting plate with the two operating levers and turn the socket wrench over the extension in Direction of rotation is taken.

The ends of the extension and the actuating lever that can be inserted into the recesses in the mounting plate can each have a locking pin which, contrary to the action of a spring, transversely to the insertion direction into the The end can be pressed in and with its locking head protruding from the end in one of the recess to the Engaging the side surface of the mounting plate reaching breakthrough. With these locking pins are the two Operating lever and the extension of the socket wrench are reliably attached to the mounting plate.

The locking heads of the locking pins protruding into the openings in the mounting plate can be used to dismantle the extension the socket wrench and the two operating levers by inserting a thin tool, such as Screwdriver or the like. In the opening in the release position to be convict. It is thereby achieved in a simple manner that the two »operating levers and the Extension of the socket wrench is not unintentional

νοη can loosen the mounting plate. Only by Inserting a thin tool, such as a screwdriver or the like, into the opening in the mounting plate the locking pin is transferred into the release position, so that now the respective actuating lever or the extension of the socket wrench can be pulled out of the mounting plate.

The socket wrench can be formed by a socket wrench insert and can be released via a standardized square be connectable with the extension. This can be used in a simple manner as a socket wrench itself known socket wrench inserts are used, which in a simple manner via a standardized square with the extension are connectable.

The mounting plate can be round, with the four recesses in the cylindrical outer surface are provided. This results in a relatively long time in a simple manner with little material expenditure Guides created for the inserted operating lever or extensions for the socket wrench. Of the The cost of materials can be reduced even further by placing the round mounting plate in the middle a breakthrough is provided.

In the drawing, the invention is shown in an exemplary embodiment, namely show:

Fig. 2 is a section along the line II-II of Figs. 1 and

Fig. 3 shows an extension rod that is associated with a square is provided for placing a socket wrench insert.

The cross key shown in the drawing is used to operate wheel nuts of trucks and is shown in Fig. 1 on a reduced scale. FIGS. 2 and 3 show true-to-scale representations the corresponding parts of the cross-wrench.

The cross wrench consists of a socket wrench 10, at its coaxially to the axis of rotation of the socket wrench 10 extending extension 11 two at right angles to Extension 11 of the socket wrench 10 arranged, offset by 180 ° to each other arranged actuating lever 12 are provided. Each of the two operating levers 12 has a length such that the lever arm to the axis of rotation of the socket wrench 10 is about 38 cm. In order to save space for the To enable cross-wrench, the two operating levers 12 and the extension 11 of the Socket wrench 10 releasably connected to one another via a mounting plate Ij. The mounting plate 13 is round and has four recesses 15 in the cylindrical outer surface 14 which oppose one another are offset by 90 °. Furthermore, the round fastening plate 13 has an opening in the middle 16 on. With this breakthrough, the weight of the mounting plate 13 is reduced, without the strength to affect the mounting plate 13. In the

four recesses 15 of the mounting plate 13 are the extension 11 of the socket wrench 10 and the both actuating levers 12 can be used in a rotationally fixed manner. For this purpose, the recesses 15 have a non-circular, i.e. hexagonal cross-section. The extension 11 of the socket wrench 10 and the two actuating levers 12 have a corresponding non-circular, i.e. rectangular, cross-section at their insertion ends 17.

As can be seen from FIG. 1, the fastening plate 13 is located in the recess 15 directed downwards the extension 11 of the socket wrench 10 is used while in dan both to the right and left Recesses 15 of the mounting plate 13, the two actuating levers 12 are used. When you press the Cross-wrench according to the invention, the two actuating levers 12 with the mounting plate 13 are around the axis of rotation of the socket wrench 10 rotated, the fastening plate 13 rotatably the extension 11 of the socket wrench 10 takes with it.

In the upwardly directed recess 15 of the mounting plate 13, another actuating lever can be used 12 or a further extension 11 with another socket wrench 10 can also be used To be able to operate wheel nuts with a different wrench size. Basically, however, it is for the user only required that socket wrench 10 with extension 11 is present, the socket wrench has such a wrench size that is required for the wheel nuts of his truck. to With this socket wrench 10 with extension 11, the user then needs two actuating levers 12. Of course it is also possible instead of the actuating lever 12

other extensions 11 with socket wrench 10 can be used.

Of course, it is also possible to use the socket wrench 10 to form from a not shown, known per se socket wrench insert that is detachable via a standardized square 18 can be connected to the extension. This allows socket wrench inserts in a simple manner can be used with different key widths on the cross key.

The insertion ends 17 of the extension 11 that can be inserted into the recesses 15 of the fastening plate 13 of the socket wrench 10 and of the actuating levers each have a locking pin 19 which, contrary to the Effect of a spring 20 can be pressed transversely to the insertion direction into the insertion end 17 and with his from the end 17 protruding locking head in one of the recess 15 to the side surface 22 of the mounting plate reaching breakthrough 23 engages. With this locking pin 19 can thus the actuating lever 12 and the extension 11 of the socket wrench 10 are reliably held on the mounting plate 13, without the insertion ends 17 slipping out of the recesses 15 of the fastening plate 13 is feared. The latching heads 21 of the latching pins protruding into the breakthroughs 23 of the fastening plate 13 19 are for dismantling the extension 11 of the socket wrench 10 and the two actuating levers 12 by inserting a thin tool, such as a screwdriver or the like., In the opening 23 in the release position transferable.
