vehicle bodies or frames

The hiring relates to a device for straightening and sifting out damaged motor vehicle bodies or frames. The straightening and pulling out of indented body parts and vehicle frames is done in the workshops with the help of special devices. However, these devices, whose stability is required because of the forces that occur, are not cheap, so that it is difficult to buy them, especially for small or medium-sized motor vehicle repair shops. The aim of the innovation is, therefore, such a device to be created eikj which is characterized with a robust, operationally reliable construction by substantially lower production costs and which also particularly versatile einsetabar 1st and especially ffr small and medium workshops out of the question.

For this purpose, the device according to the innovation is characterized in that it is designed as an accessory to a vehicle jack known per se with a movable flat frame and a bar arm that can be pivoted about a horizontal axis out of a substantially horizontal rest position and one at the Hubaam

of the jack rigidly attached near its axis of rotation has upright pull arm to which the body or the frame can be coupled via a cable 1st and that the frame of the jack is connected to a horizontal beam aligned with the pulling arm, who wears a stumbling block that can be discounted against the body or the frame.

It is advantageous if a claw is attached to the lifting arm of the jack into which the pulling arm is releasably inserted so that the pull arm can be removed from the jack. The beam is in a preferred one Embodiment of a substantially U-shaped fork that encompasses the frame of the jack in a clip-like manner fastened with their thighs on both sides against

the extended axis of rotation of the lifting arm is supported, which results in a very high stability of the entire device. In order to be able to remove the bar carrying the drag shoe, the legs of the fork are expedient with open-edged recesses caught in the pin of the axis of rotation and secured there by inserted pins, while the fork carries a downwardly protruding, in white L-shaped support foot, which is preferably encompasses a wheel axle of the jack frame »

Pie n «« e device has the advantage that it is designed as an additional device for a normal car jack, so that it results in substantial cost savings compared to known devices, while on the other hand the car jack can be used on its own at any time, so that you can buy one additional lifting device is not necessary.

Further advantageous features and properties of the device according to the invention emerge from the following description of a shown in the drawing Embodiment of the subject of the innovation

The device shown in the drawing sum straightening and lending out damaged motor vehicle bodies or frames is designed as an accessory to a jack 1 · The jack 1 is equipped with a roller 2, 3 movable flat frame 4 provided in which a lifting arm 5 from a substantially horizontal rest position (Flg. 1) is mounted pivotably about a horizontal axis 6 1st. The pivoting of the lifting arm 5 is done by means of of a hydraulic cylinder indicated at 7 »whose operation · ^ Authorization via an operating rod 8 takes place · jack of the type described are in some Ausfütarungsformen known, so that no further explanation is necessary An upright pull arm 9 is rigidly attached to the lifting arm 5 of the jack 1 near the axis of rotation 6, on which a cable 10 is not shown welter The body or the motor vehicle frame in the form shown in FIG. 1 is apparent way can be coupled. To attach the pull arm 9 1st to the lifting arm 5 is an approximately ring-shaped one Welded claw 11 into which the pull arm 9 can be releasably inserted. The pull arm 9 runs between the parallel traverses 5a and 5b forming the lifting arm 5, which can be seen from FIG.

"Selling 10" clamped HemmseBUB 13 against the body or the frame is sprinkled. Now becomes the jack When actuated in the sense that the lifting arm 5 pivots from the horizontal rest position near the top, the pulling arm 9 is rotated clockwise (Fig. 1) about the axis of rotation 6. The pressed-in body or frame part is thus stretched over the cable 10, with the body or the frame is calibrated against the drag shoe 13. The point of attack 23 is Seilemgee 10 on em Zagat optionally adjustable in height, whereby the lever translation of the derate can be changed according to the respective requirements.

Should the jack 1 only be used for her. The fork 14 with the bar 12 can be removed after the pins 17 have been removed, while the pull arm 9 can be pulled out of the claw 11, with which the jack is sowed without any annoying additional parts It is a special advantage of the new device that on the one hand it is ready for use in a few minutes, while on the other hand the jack is immediately available alone if necessary. Besides, they are on minor changes to be made to a standard jack in order to use it as a new feature su can. Ss is essentially sufficient to counteract the axis of rotation to replace an extended axis of rotation 6 and the claw to be welded on.
