Abstract

A height-adjustable device has synchronously height-adjustable lifting devices each having a standing and lifting element, which are height-adjustable relative thereto. The height adjustment is configured to be carried out via pulling elements, formed by redirection devices, to raise the lifting element relative to the standing element. Each pulling element is secured in a non-positive or positive locking manner to lifting devices, and each are configured such that a lengthening in the region of the first lifting device brings about a synchronous shortening in the region of the second lifting device. Each pulling element is constructed to raise only the one lifting element relative to the standing element. The height-adjustable device has a locking device that locks the pulling elements by a non-positive or positive locking engagement on the corresponding one of the pulling elements. The locking device is constructed to synchronise the movement of the pulling elements.
