Embodiment Construction

[0099] The spindle 1 is threaded and turned slightly at one end so that the spindle driver 2 can be pressed or welded in. On the other end, the mandrel 1 is partially extruded into 1a. The spindle driver 2 is a disk with a hole in the middle, which corresponds to the twisted part of the spindle. The outer circumference of the spindle driver 2 is polygonal (for example hexagonal) and is configured according to the inner polygon of the guide tube 3 .

[0100] The guide tube 3 is a thin-walled polygonal tube (for example a hexagonal tube) having a hole 3d with an inward radial wall 3a on one side and an outward radial wall 3b on the other side. The hole 3d is slightly larger than the diameter of the mandrel 1 . The spindle driver 2 is supported on the inner radial wall 3 a, wherein the spindle 1 can be moved axially within the guide tube 3 by means of the spindle driver 2 . By means of a polygonal allen wrench (eg a hexagonal allen wrench) positioned on the other side of the g...

Abstract

The present invention relates to a scissor car jack comprising a spindle (1), a base (15), a support head (16), a traverse (6) and a spindle support (8) having a hole with an inner threading for holding the spindle (1), wherein the base (15) and support head (16) are rotatably connected to the traverse (6) and the spindle support (8) by way of a respective support arm (10, 11, 12, 13), and wherein the support arms (10, 11, 12, 13) are connected with one another in the area of the base (15) and the support head (16) and/or in the area of the traverse (6) and the spindle support (8), and the spindle (1) is coupled to the traverse (6) and the spindle support (8) so that when the spindle (1) is rotated, the distance between the spindle support (8) and the traverse (6) can be changed. The length of the support arms (10, 11 and 12, 13) can be changed telescopically and can be locked in the extended state by way of locking pins (14) so that the scissor car jack can be collapsed into a smaller volume, in particular for purposes of stowage.

Description

technical field [0001] The invention relates to a lift according to the preamble of claim 1 . Background technique [0002] It is known to lift a car by means of a lift in order to change a tire. Since the trunk of a car is now completely packed with different components and equipment, the lift should also have small dimensions in order to be able to be accommodated. Here, of course, the reliable functioning of the lift must not be impeded. A scissor lift is known from DE 10 2004 003 177 B4, in which the kinematic points are connected by means of integral support arms. When folded, the aforementioned lift has a maximum length which is proportional to the lift height. In the case of a large lifting height, the lift is difficult to install in the trunk of a car. Contents of the invention [0003] It is therefore the object of the present invention to provide a scissor lift which can be converted into a smaller transport volume for storage without impairing functional rel...
