Adjusting mechanism for table working height

摘要

The parallel links (1,2) are attached at one end to two points (6a,6b) on the supporting frame (3). It is attached at the other end to two further such points (6c,6d) on a guide member (4) underneath the table (11) and sliding parallel to it. The table is fixed in position in the horizontal direction in relation to the frame by a further link (5) between the midpoint (5b) of one of the first links and a fixed point (5a) on the table. The first links and their guide members can be joined together by crossmember.
