Abstract

The invention relates to a sliding door fitting comprising a carriage, which is guided on a guide rail and which is connected to a housing of a retraction device in an articulated manner, wherein the retraction device has at least one, preferably two driver elements, which can be moved along guide tracks and which are spaced apart, the one or more driver elements being preloaded into a retraction position by means of at least one force accumulator, wherein the housing of the retraction device is preloaded in a direction rotation relative to the carriage.

Claims (12)

1. A sliding door fitting having a first carriage guided on a guide rail, wherein the first carriage is connected in an articulated manner to a housing of a retraction device, wherein the retraction device has at least one driver which can be moved along a guideway defined by the housing of the retraction device and which is pretensioned into a retraction position via at least one energy accumulator, wherein the housing of the retraction device is pretensioned in a first direction of rotation relative to the first carriage, the sliding door fitting further comprising an elastic element operably associated with the housing of the retraction device and the first carriage and configured to pretension the housing of the retraction device in the first direction of rotation relative to the first carriage, and an adjusting element configured to variably deflect the elastic element in order to apply a torque to the housing relative to the carriage.

2. The sliding door fitting according to claim 1 , wherein at least one roller is provided on the housing of the retraction device on an end remote from the first carriage, which roller is pretensioned and rests against a guideway of the guide rail.

3. The sliding door fitting according to claim 1 , wherein the driver can be parked and locked against the force of the energy accumulator when the energy accumulator is tensioned.

4. The sliding door fitting according to claim 1 , wherein the driver can be coupled to an activator which is fixed in the guide rail.

5. The sliding door fitting according to claim 4 , wherein the activator is fixable to the guide rail in plural locations with respect to the longitudinal direction of the guide rail.

6. The sliding door fitting according to claim 1 , wherein an axle of the carriage is enclosed by an end of the housing of the retraction device by a holder.

7. The sliding door fitting according to claim 1 , wherein a leaf spring or a spiral spring is provided for pretensioning the housing of the retraction device.

8. The sliding door fitting according to claim 1 further comprising a second carriage, wherein the housing of the retraction device is arranged between the first carriage and the second carriage.

9. The sliding door fitting according to claim 1 , further comprising a second driver spaced apart from the driver, wherein the driver and the second driver are connected to one another via a single energy accumulator.

10. The sliding door fitting according to claim 9 , wherein the driver and the second driver are braked in the retraction direction by at least one damper.

11. The sliding door fitting according to claim 10 , wherein the at least one damper comprises a first damper and a second damper two dampers provided in the housing of the retraction device wherein the first damper is configured to brake the first driver, and where the second damper of the two dampers is configured to brake the second driver.

12. The sliding door fitting of claim 1 , wherein the driver is braked in the retraction direction by at least one damper.
