Device for pressing running roller onto guide rail of support tube

摘要

The pressure component (6) presses with a defined spring force against the running roller (4) which is firstly radially movably held and then secured. The pressure component has at least one pressure pin, which is effectively connected to a pressure spring (13) and supports on the running roller (4). Two parallel and spaced apart pressure pins (7) are provided, which engage symmetrically on the running roller. The pressure pins are fixed to a pressure plate (11), on which the pressure screw spring (13) supports and also locates on the base of a recess (14) of a casing (12). The pressure pins are fed through a holding plate (8) and penetrate holes (15) in a guide slide (1).
