Abstract

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.

First claim

What is claimed is:

1. A door fitting ( 20 ) with height adjustment for a sliding door ( 1 ) which is movable between a closed rest position ( 24 ) and an open end position, the door fitting comprising: a housing ( 31 ) including opposite side walls ( 32 , 33 ) with at least one support roller ( 41 ) rolalably 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 ( 54 ) formed in the opposite side wails ( 32 , 33 ) of the housing ( 31 ), each of the inclined guide paths ( 54 ) having first and second end stops ( 56 , 57 ) of which first end stop ( 56 ) defines a lower end position and the second stop determines an upper end position of the sliding door ( 1 ),
each inclined guide path ( 54 ) having an entrance area ( 52 ) formed at the second end stop ( 57 ) of the inclined guide path ( 54 ), and
a returned element ( 23 ) connected to the housing and to the lifting member ( 61 ) so as to bias the lifting member ( 61 ) with the guide elements ( 65 ) relative to the housing ( 31 ) in a direction toward the first end stop ( 56 ).

2. The door fitting according to claim 1 , including an adjustment device ( 21 , 69 ) with an adjustment element ( 21 ) for moving the lifting member ( 61 ) toward the second end stop ( 57 ) thereby raising the lifting member ( 61 ) and together herewith the sliding door ( 1 ) relative to the housing ( 31 ).

3. The door fitting according to claim 1 , including an acceleration and deceleration arrangement ( 81 ).

4. The door fitting according to claim 1 , wherein the lifting member ( 61 ) includes two longitudinal webs ( 62 ).

5. The door fitting according to claim 1 , wherein the guide elements ( 65 ) have an oval cross-sectional area.

6. The door fitting according to claim 1 , wherein the inclined guide paths ( 54 ) are arranged in the housing ( 31 ) and the guide elements ( 65 ) are arranged in the lifting member ( 61 ).

7. A sliding door ( 1 ) with at least one door fitting ( 20 ) according to claim 1 .

8. The sliding door ( 1 ) according to claim 7 , wherein the lifting member ( 61 ) has longitudinal webs ( 62 ) which extend around a threaded sleeve ( 7 ) of a support frame ( 3 ) of the sliding door ( 1 ).
