摘要

#CMT# #/CMT# The device has a central pivot (1) for folding and unfolding legs of a trestle or bench, where the legs are folded below a bearing crossbeam. A hinge comprises wings (2, 2`) which are pivotable through rotation. The wings are screwed on the legs for ensuring lateral opening of the legs with an angle between 20 degrees to 30 degrees. A support (3) permits the positioning of the legs and blocks the opening of the legs. #CMT#USE : #/CMT# Used for folding and unfolding legs of a trestle or bench (claimed). #CMT#ADVANTAGE : #/CMT# The central pivot permits the folding of the legs of the trestle or bench below the bearing crossbeam, thus reducing encumbrance during transportation and reducing storage without harming solidity of the legs. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a leg folding and unfolding device. 1 : Central pivot 2, 2` : Wings 3 : Support.
