Length-adjusting mechanism for chair and table components - has actuating pin locked by curved plastics leaf-spring supported at two points and has lateral guide faces for the lever

摘要

The spring (26) is of the curved leaf-type and preferably of plastics. It is supported at two diametrally-opposite points (16h) in relation to the pin (14n), being curved between these points or alternatively, from the housing sides. The spring can be pre-loaded, but for an amount less than the force holding the pin in the locked position. It can have lateral guide faces for the portion of the lever (22) inside the housing. USE/ADVANTAGE - For telescopically adjusting height of furniture. Small number of components and prevents incorrect adjustment.
