Definitions

the invention relates to a jack for motor vehicles of the type explained in the preamble of claim 1.
the known jack has the disadvantage that it has to be pushed completely under the motor vehicle so that the lifting curve of the load head can follow the tilting movement of the motor vehicle, which makes the threaded spindle, which is located directly on the ground, difficult to access.
a modified embodiment of a jack for motor vehicles according to the preamble of claim 1 is known, in which the articulated arrangement of the jack is designed so that it can be attached laterally outside the motor vehicle. Operation is facilitated by a slightly higher position of the actuating end of the threaded spindle.
the base part is articulated to a foot part, in which the support arm can be supported in two different positions, and this foot part enables the load head to have a lifting curve, which can roughly follow the tilting of the motor vehicle by pulling up the base part relative to the foot part.
the object of the invention is to improve a jack for motor vehicles of the type explained in the preamble of claim 1 in such a way that easier handling of the jack is achieved with improved functionality.
a jack for motor vehicles according to the preamble of claim 1 has the features shown in the characterizing part of claim 1.
the base part has a U-shaped cross-section and has in the vertical side walls, slightly S-shaped link slots, in which the bolts of the nut piece are guided, a lifting curve of the load head is achieved which, when the base part rests, the tilting movement of the motor vehicle that occurs corresponds and thus ensures high stability and functional reliability.
the car jack shown in FIGS. 1 to 3 essentially consists of a base part 1 with a deep U-shaped cross section, which has vertical side walls 2 and 3 with adjoining outwardly angled reinforcing flanges 4 and 5.
a threaded spindle 7 is arranged, the load-side end of which is supported by a spindle bearing 8 in a bearing block 9 and the actuation-side end of which is supported by a nut piece 10 and bolts 11 extending perpendicular thereto in lying, slightly S-shaped link slots 12 is.
the free end of the threaded spindle 7 has an actuating ring 13.
a cantilevered load arm 14 is supported with its fork-shaped end 15 on the bolt 11 on the nut piece 10 and carries at its free end a load head 16 which is adapted to the receptacle on the motor vehicle.
a support arm 17 hinges on a pin 18. The other end of the support arm 17 is supported by a bolt 19 in the vertical side walls 2 and 3 of the base part 1.
the load arm 14 and the support arm 17 are, as can best be seen from FIGS. 4a to 4d, designed as rigid, U-shaped cross-sections.
both the base part 1 and the bearing block 9 as well as the load arm 14 and the support arm 17 are designed as stable sheet-metal pressed parts.
the actuating end of the base part 1 is lifted somewhat off the floor by means of a support leg 20.
the jack is placed on the floor with its horizontal base part 1 and the foot 20 and the lower fork-shaped end of the load arm 14 is placed on the bolts 11 on the nut piece 10.
an initial height of the load head 16 can be set, from which the actuation begins.
the cumbersome and time-consuming turning of the threaded spindle 7 can be considerably reduced.
the nut piece 10 moves along the slightly S-shaped link slots 12 in the direction of the spindle bearing 8 and thereby urges the load arm 14 and the support arm 17 via the articulated connection with the bolt 18 up.
the load head 16 moves here along the stroke curve indicated by construction steps, which clearly follows a tilting movement of the motor vehicle.
the threaded spindle need only be actuated until the load head 16 is released from the motor vehicle. If you now pull the jack out from under the motor vehicle, you can disengage it with its fork-shaped end from the bolts 11 on the nut piece 10 by slightly lifting the load arm 14, as a result of which the jack can be fully folded without the nut piece 10 being in its outermost position End position must be turned. When the jack is used again, the initial height required for the motor vehicle can then be set immediately by hooking in the fork-shaped end 15 of the load arm 14.
