DOOR FITTING FOR THE HEIGHT ADJUSTMENT OF SLIDING DOORS

摘要

In a door fitting with height adjustment for a sliding door panel with a housing in which a support roller is rotatably supported, a sliding door panel lifting member is slidingly supported by guide elements extending from the support base member into inclined guide passages formed in the housing side wails whereby the sliding door panel can be raised or lowered by longitudinal movement of the lifting member relative to the housing, the inclined guide passages are provided with end walls which limit the movement of the guide elements in the inclined passages to limit the height adjustment and an access area is formed at an upper end of each guide passage. Adjustment elements are provided for the movement of the base member relative to the housing.

1. A door fitting (20) for height adjustment of a sliding door (1) movable between a closed rest position (24) and an open end position, comprising: a housing (31) with at least one support roller (41) rotatably supported in the housing (31), a lifting member (61) adjustably disposed in the housing via at least four guide elements (65) engaged in inclined guide paths formed in opposite side walls of the housing (31), each of the inclined guide paths having first and second end stops (56, 57) of which the first end stop (56) defines a lower rest position and the second end stop (57) determines the upper end position,
each inclined guide path (54) further having an entrance area (52) formed at the second end stop (57) of the inclined guide path (54), and a return element (23) connected to the housing and to the lifting member (61) so as to bias the lifting member (61) relative to the housing (31) in a direction toward the first end stop (56).
