PEW ^ cross key

The present invention relates to a cross key ins-,
special for passenger cars. Bie known cross keys are in one piece and accordingly rigid, which is why they require a relatively large amount of tree and, for example, only housed in a spacious tool bag
can be.

The invention is based on the object of creating a cross key which is stored in a space-saving manner when it is used
can be. '

This is according to the invention achieved by the fact _t that the two arms of the cross key umgihren Kreukungspunkt be formed collapsible "Me both arms of the cross key konnea herein in their Kreugungspunkt a screw with
Mother,

the screw advantageously being rigidly attached to an arm is and protrudes through a hole in the other arm. After loosening the nut, the cross wrench can be used Fold up to a flat, steel-shaped structure and store it to save space.

So that the two arms of the cross wrench are secured against accidental collapse in their crossed operating position are and can absorb large torques, according to the invention is also provided that the two arms on Trough-shaped indentations lying opposite one another at their point of intersection for non-rotating mutual accommodation the poor possess. According to a further feature of the invention, the indentations consist of forged impressions, wherein the material displaced during forging reinforcement beads in the area of the crossover point of the arms forms.

According to further features of the invention, one arm is mounted axially displaceably on the screw and has the Screw a length roughly equal to the total width of two Working heads, "

In a further embodiment of the invention, one of the working heads of the cross wrench can be designed as a wheel cap removal tool be, which saved a separate bath cap puller for the tooling of passenger cars

will.

The invention is illustrated below with reference to the drawing in two Exemplary embodiments explained in more detail, showing:

Fig. 1 in front view of a cross key, in operating positionj according to a first embodiment of the invention,

Pig 2 shows the cross key according to FIG. 1 in side view and when folded and

Fig. 3 shows a second embodiment of the cross key in Side view and folded state, in which a working head is used as a wheel cap removal tool is trained.

The cross key shown in FIGS. 1 and 2 consists essentially from the two arms 1, 2 with the working heads 11, 12, 21, 22 and the screw 3 with wing nut 4-, The two arms 1, 2 have trough-shaped indentations 13 opposite one another in the area of their intersection point. 23, which are made by forging, wherein the displaced material forms reinforcing beads 14-, 2S-, which the Reinforce arms 1, 2 in the area of their crossing point. the Indentations 13, 23 are dimensioned such that they are reused when Position of the arms 1, 2 for the mutual inclusion of Crossing arms are suitable. Through the hereby achieved

109825/0139

The cross key can protect against rotation in its operating ^ position high torque loads.

The screw 3 is rigidly attached to the arm 2 and protrudes through a hole in the arm 1 therethrough. The screw 3 has a length approximately equal to the total width of two working heads 11, 22, so that the two arms 1, 2 are initially at a distance corresponding to the illustration in FIG. Figo 2 can be moved apart. .

The cross key according to FIG. 3 corresponds to that according to FIGS. 1 and 2 with the only difference that here, instead of the key working head 11, a wheel cap removal tool 11a is provided.
