Anordning för relativ förflyttning av två element

摘要

The linkage connects base element (1A) with floating element (2) which is to be positioned in space. The linkage incorporates a link arrangement (5) and a movement arrangement (6). The link arrangement has links (9) which are joined to connector (4) and the floating connector by multi-directional pivots. The links of the link arrangement are parallel and equal in length. The movement arrangement allows relative movement between the connector and the base element and allows the connector to be moved without changing its orientation in space. The links of the movement arrangement form at least one parallelogram between the connector and the base element.
