Abstract

The invention relates to a lifting device (1) comprising a top part (3), a bottom part (2), a lifting rod assembly (4) that connects the top part (3) to the bottom part (2) and is provided with at least two partial rod assemblies (5, 6) which are interconnected via a central joint (16), and a drive unit (12, 14, 15, 19) for adjusting the height of the top part (3). In order to create a particularly simple lifting device, the drive unit (12, 14, 15, 19) grips the central joint (16).

Description

technical field

[0001] The invention relates to a lifting device with a top and a bottom, comprising a lifting rod connecting the top and the bottom and a drive unit for adjusting the height of the top, the lifting rod has at least two struts connected by an intermediate hinge joint. Background technique

[0002] Such lifting devices are known from the prior art. For example WO98 / 46137 shows such a lifting device for adjusting the height of a hospital bed. Among them, the lifting rod uses a parallelogram structure. A disadvantage of the known construction is that it requires a relatively large installation space. Furthermore, particularly large but not constant forces are required for the height adjustment. During height adjustment, different working speeds also occur. In other words, the known solutions are structurally complex and require an overly complex control. Contents of the invention

[0003] In view of this situation, the technical problem to be solved by th...
