Patent number: 6826868Abstract: A slim-frame door is guided in a guide rail by a sliding piece. The door includes a hollow section in which a compensating element is displaceably arranged, the compensating element being connected to the sliding piece and being capable of moving in the vertical direction in the hollow section in order to compensate for slopes present between a horizontal edge of the sliding door and the guide rail as the sliding door is moved. At least one end in its direction of movement, the sliding piece has a wedge which prevents the sliding piece from jamming on small objects in the guide rail. A pivoting fitting includes a carrying arm arranged in a carrier section, and a shaft fixed in a horizontal section of the door leaf. The door leaf is pivotably mounted on the carrier section.Type: GrantFiled: March 27, 2002Date of Patent: December 7, 2004Assignee: DORMA GmbH + Co. KGInventor: Andreas Finke
