Device for supporting equipment e.g. auxiliary table, has one set of posts connected to another set of posts of trestle respectively by compasses to maintain cross-pieces in horizontal plane

摘要

The device has a base trestle provided on feet in which posts (3a-3d) are articulated. Two of the posts and other two posts are connected by corresponding cross-pieces (2a, 2b), such that the cross-pieces and upper points (7a, 7b) of the trestle are in a same horizontal plane (h). The posts are connected to posts (9a-9d) of trestle respectively by using compasses (6a- 6d) to maintain the cross-pieces in the horizontal plane same as the cross-pieces of the trestle.
