Mechanism for regulating length, particularly of furniture legs

Abstract

A mechanism for regulating length, particularly of furniture legs, meant for use in various legs of tables, desks, cupboards, spreaders, frames, supports, and other structural elements of furniture, in which it is desirable to quickly and easily regulate length, characterised in that it is made in the form of interacting, incrementally sliding and rotating external element ( 1 ) threaded inside and a telescopic collapsing internal element ( 2 ), which comprises a blocking-locking assembly for interacting with the thread of the external element ( 1 ) preferably in the form of a blocking element ( 3 ) as well as a locking element with an unlocking tooth ( 4 a ) wherein the blocking element ( 3 ) is friction inserted under the locking element with unlocking tooth ( 4 a ) by the stabilising flange of the external element ( 5 a ) and unlocked by the unlocking tooth of the locking element ( 4 a ) or in the form of a blocking element ( 3 ) interacting with the locking ring ( 4 ) sliding onto it, and the locking ring ( 4 ) is slid off using the retracting pin ( 7 ).
