Patent ID: 8596899

Claim:
An apparatus adapted to be fastened to rail elements for releasably locking two rail elements ( 10 , 11 ), which are supported displaceably relative to each other, of a telescopic rail or a linear guide and for adjusting the motivity to be applied for the displacement, comprising a housing ( 1 ) which is adapted to be fastened to a first one of the rail elements ( 11 ) which are supported displaceably relative to each other, at least one locking element ( 5 ) and at least one locking force spring ( 4 ) which is supported against the housing and being adapted to bias the locking element ( 5 ) against the second of the rail elements ( 10 ) which are supported displaceably relative to each other, at least one friction element ( 7 ) and at least one friction force spring ( 6 ) which is supported against the housing and which is adapted to press the friction element ( 7 ) in biased relationship against the second of the rail elements ( 10 ) which are supported displaceably relative to each other, wherein the at least one locking force spring ( 4 ) and the at least one friction force spring ( 6 ) are in the form of coil springs of differing diameters and are coaxially aligned.
