Abstract

In a sliding door comprising a first frame element oriented in the longitudinal direction of the sliding door and a second frame element extending normal to the first frame element and being connected thereto, wherein, in an opening formed at least in the first frame element, a door fitting is disposed which includes a support roller and a lifting member which is height-adjustable between a lower rest position and an operating position, the door fitting includes a stop spaced from the support roller. In the rest position, the lifting member is closest to the support roller. The operating position is adjustable by an adjustment element moving the lifting member toward the operating position in an inclined guide structure against the force of a return arrangement.

First claim

What is claimed is:

1 . A sliding door ( 1 ) comprising a first frame element ( 4 ) extending in the longitudinal direction of the sliding door ( 1 ), a second frame element ( 11 ) extending normal to the first frame element ( 4 ) and being connected thereto, at least the first frame element ( 4 ) having an accommodation opening ( 165 ) with a door fitting ( 20 ) with a housing ( 31 ) disposed in the accommodation opening ( 165 ), the door fitting ( 20 ) including a support roller ( 41 ) rotatably mounted in the housing ( 31 ) and a lifting member ( 61 ) supported in the housing ( 31 ) so as to be movable between a rest position ( 24 ) and an operating position, the door fitting further including a stop ( 89 ) which is spaced from the support roller ( 41 ), the lifting member ( 61 ) having in its rest position ( 24 ) a smallest distance from the support roller ( 41 ) and the housing including an adjustment arrangement ( 21 ) for pulling the lifting member ( 61 ) toward the operating position against the force of a return arrangement ( 23 ) biasing the lifting member ( 61 ) toward the rest position ( 24 ).

2 . The sliding door ( 1 ) according to claim 1 , wherein the adjustment arrangement ( 21 ) includes an adjustment screw which is supported by the second frame element ( 11 ) transferring the lifting member pulling force to the second frame element ( 11 ).

3 . The sliding door ( 1 ) according to claim 1 , wherein the stop ( 89 ) is provided by the first frame element ( 4 ).

4 . The sliding door ( 1 ) according to claim 1 , wherein the lifting member ( 61 ) is supported in the housing ( 31 ) by inclined guide slots ( 51 ) so as to be movable from the rest position at the lower end of the slots ( 5 ) to a higher operating position spaced from the lower end of the guide slots ( 51 ).

5 . The sliding door ( 1 ) according to claim 1 , wherein the door fitting ( 20 ) includes an acceleration and deceleration arrangement ( 81 ).

6 . The sliding door ( 1 ) according to claim 1 , wherein the housing ( 31 ) of the door fitting ( 20 ) abuts the second frame element ( 11 ).

7 . The sliding door ( 1 ) according to claim 1 , wherein the lifting member ( 61 ) engages a threaded sleeve ( 7 ) extending in the longitudinal direction ( 15 ) of the sliding door ( 1 ) and abuts a transverse web ( 6 ) of the first frame element ( 4 ).

8 . A sliding door arrangement comprising a sliding door ( 1 ) according to claim 1 , wherein the support roller ( 41 ) is movable along a door track ( 140 ) of the sliding door arrangement and the door track ( 140 ) is provided with a carrier ( 150 ) adapted to be engaged by, or disengaged from, the acceleration and deceleration arrangement ( 81 ).

9 . The sliding door arrangement according to claim 8 , wherein the carrier ( 150 ) is symmetrical with respect to a center transverse plane thereof.
