Definitions
- the invention relates to a jack according to the preamble of claim 1.
- Car jacks of this type are required in order to be able to lift cars in the event of a breakdown, for example in order to replace a defective wheel with the spare wheel.
- DE-A-24 44 132 shows such a jack with a single leg and a support arm movably fastened about a horizontal pivot axis, which are pivoted against one another as a moving element via a threaded spindle connected directly to them.
- the pillar and support arm are pressed metal parts with a U-shaped cross-section.
- the side bars of the profiles for the supporting leg and support arm are connected at right angles, almost to the bottom of the profile with a sharp edge.
- a disadvantage of a jack of the prescribed design results in a high weight for a part that is only required in special exceptional cases and must otherwise be moved with the vehicle as ballast.
- the jack has a lower weight with the same load capacity. In addition, it requires less storage space in the vehicle.
- the jack has a support leg 1 with an attachment foot 2 arranged at its lower end.
- a support arm 4 is rotatably connected to the support leg 1 via a horizontal pivot axis 3. It has a support plate 5 at its upper end.
- a movement element 8 is connected directly to the support arm 4 and the supporting leg 1.
- the movement element 8 is designed as a threaded spindle 9 which interacts with a nut in the articulation point 7 on the supporting leg 1.
- a hand crank 10 is used to turn the threaded spindle 9.
- the foot 2 stands on the floor 11, and the support arm 4 engages with its support plate 5 under the vehicle 12 to be lifted.
- Fig. 2 shows a further embodiment of the jack according to the invention. It in turn consists of a leg 1 with a base 2 and a supporting frame 4 with a supporting plate 5, which are connected to one another in a rotatable manner via a horizontal pivot axis 3.
- a parallelogram linkage consisting of two parallelogram arms 15, 16, is connected to the support arm 4 and the base 2 via two articulation points.
- the movement element in turn consists of a threaded spindle 9 with a hand crank 10 which, via a movement nut, in this case arranged in the pivot axis 3, effects the adjustment of the jack.
- the profiles are composed of two side webs 18, 19 and a base 20.
- the bottom is convex in all cases.
- the distance 21 from the center 22 of the base 20 to the transition 23 between the side webs 18, 19 and the base 20 is at least 20% of the width 24 of the side webs 18, 19.
- the bottom shape of the profile cross-sections is semicircular in example a, curved in example b and roof-shaped in example c, the saddle point of the roof being flattened.
