Description

The present invention relates to a fitting for a sliding door, with a roller carrier on which one or more rollers are rotatably mounted, which roll on a rail, wherein on the roller carrier a Aushebsicherung is guided, which allows lifting of the roller carrier in a first position and prevented in a locked second position lifting the roller carrier from the rail.

The DE 202 12 222 U1 discloses a roller carrier for sliding doors, in which a cross-sectionally U-shaped support member is provided, at the connecting portion of a horizontally displaceable molded part is provided. The molding can engage under a web of the rail to secure the roller carrier to a rail with a boom. If the molded part is moved horizontally, the roller carrier can be released and lifted off the rail. In this roller carrier is disadvantageous that a relatively large footprint in the horizontal direction is required by the horizontally movable molding.

It is therefore an object of the present invention to provide a fitting for a sliding door in which a Aushebsicherung is provided in a compact design, which is easy to operate.

This object is achieved with a fitting with the features of claim 1.

According to the invention, the fitting comprises a lift-off, which has a tab which engages under the rail in the locked position and is designed to be lowered from the rail for unlocking. The lift-off is thus move in the vertical direction to secure the roller to the rail, so that in the horizontal direction only a minimal amount of space is required. In addition, the anti-lift device can be provided in a simple manner by mechanical means such as slide, pivot lever or other components.

According to a preferred embodiment, the fitting, which is designed as a roller carrier, or such comprises a fixable on a sliding door vertical wall portion on which the lift-out is slidably and / or guided. The roller carrier can also be formed only by the vertical wall portion, so that the fitting can be particularly well used for rear sliding doors.

For a secure guidance of the lift-out, this can be performed on at least one curve guide on the vertical wall portion. In this case, the curve guide for securing the anti-lifting device in the locked position can have an angled end section, in particular an end section which angles substantially in the horizontal direction. This provides a stable safeguard against lifting the sliding door in the vertical direction.

According to an alternative embodiment, the tab of the lift-out is mounted on a pivotable lever. The lever can be fixed to the roller carrier via an axis of rotation and lift or lower the lift-out. Preferably, the lever is locked in a locked position to prevent accidental unlocking.

In order to secure the lift-out in the locked position, a spring is preferably provided by means of which the lift-out is biased. The spring can be fixed to the roller carrier and rest with a bendable leg on a holding portion of the lift-out.

For a simple operation of the lift-off, it can protrude in the first position with a handle portion on the roller carrier to then lift the Aushebsicherung to lock the roller carrier and to pivot the handle portion or move.

The invention will be explained in more detail with reference to several embodiments with reference to the accompanying drawings. Show it:

12 an exploded perspective view of the fitting of 9 ,

The 1 to 3 show a sliding door 1 that have one or more fittings 2 is movably held on a furniture body. Every fitting 2 comprises a substantially plate-shaped roller carrier 3 that has several screws 4 at the sliding door 1 , optionally via a height adjustment is set. On the roller carrier 3 is a roller 5 rotatably mounted on a rail 6 is movable.

The rail 6 comprises two adjacent raceways on an angled horizontal section 7 for roles 5 , Furthermore, the rail surrounds 6 with an upper section 8th a cover plate 9 a furniture carcass, leaving the sliding door 1 hanging on the rail 6 is movable.

To accidentally lift the sliding door 1 and a lifting a caster 5 out of the running track 7 the rail 6 To prevent, a lift-off is provided.

As in the 2 and 3 is recognizable, includes the lift-out 11 an angled horizontal flap 10 that the rail 6 in the field of career 7 engages below. The lifting protection 11 is substantially plate-shaped and has an upper curve guide 12 and a lower curve guide 13 on. The two curves guides 12 and 13 are each from a bolt 14 penetrated. Furthermore, at the top of the lift-out 11 a grip section 17 formed in a recess on the roller carrier 3 is arranged.

In 4A is the lift-out protection 11 shown in a locked position. The tab 10 is located directly below the rail 6 ,

To the lift-out 11 to unlock and a lifting of the roller carrier 3 to enable, is the lift-out 11 moved down like this in 4B is shown. This creates a gap between the tab 10 and the bottom of the rail 6 so the sliding door 1 can be raised sufficiently to the caster 5 out of the running track 7 lift out.

In 5 is the lift-out protection 11 shown in detail. The upper curve guide 12 has an angled end section 16 which extends substantially horizontally and ensures that the lift-out 11 secured in the locked position. If a pin 14 in the region of the angled end portion 16 can be arranged, the lift-out 11 not be moved up. Only when the lift-out 11 over the handle section 17 was pivoted ( 4B ), the bolt leaves 14 the angled end portion 16 the curve guide 12 , allowing a lowering of the lift-out 11 is possible.

In the 6A and 6B is a modified embodiment of the lift-out 11 and the fitting 2 illustrated, in addition to the previous embodiment, a spring 20 on the roller carrier 3 is mounted. The feather 20 includes a bendable leg 21 that the lift-off 11 secured in the locked position. This is the spring leg 21 in the contour to an edge of the lift-out 11 adjusted and will when moving the lift-out 11 along the curve guides 12 and 13 bent back. In this case, the bendable leg 21 be shaped so that it is the lifting protection 11 locked in both the first unlocked position and in the second locked position.

In the 7A and 7B is the fitting 2 of the 6A and 6B shown in the locked and unlocked positions. In the locked position is the handle portion 17 slightly above the roller carrier 3 and thus can be easily grasped and within the recess of the roller carrier 3 to be moved.

In the 8A and 8B is the fitting 2 of the 6 and 7 shown in an exploded view. At the spring 20 are two cones 22 formed in corresponding openings 23 on the roller carrier 3 can be inserted. This allows the spring 20 mount easily and accurately. In addition, on the spring leg 21 also a pin 24 be formed on the roller carrier 3 is set to the cogging forces on the lift-out 11 to increase. The lifting protection 11 is about two bolts 14 on the roller carrier 3 kept movable.

In 9 is a third embodiment of a fitting according to the invention 2 shown, by means of a sliding door 1 on a rail 6 is kept movable. The fitting 2 ' includes one or more rollers 5 attached to a roller carrier 3 ' are rotatably mounted. To the sliding door 1 against a lifting out of a track of the rail 6 to secure is a lift-off 11 ' provided that an angled tab 10 ' includes the rail 6 engages below. The lifting protection 11 is via a pivotally mounted lever 12 ' liftable or lowerable.

In 10A and 10B is the lift-out protection 11 shown in the locked position, leaving the tab 10 ' below the track of the rail 6 is arranged. The lifting protection 11 ' is about a driver 14 ' to the lever 12 ' coupled. The lever 12 ' is about an axis 13 ' rotatable on the roller carrier 3 ' stored and includes a handle portion 17 ' for actuating the lift-out safety device 11 ,

To the lift-out 11 ' unlocking from the locked position becomes the lever 12 ' pivoted clockwise until the in the 11A and 11 B position is reached. By pivoting the lever 12 ' around the axis 13 ' becomes the lift-out protection 11 ' over the connecting element 14 ' lowered, leaving a gap between the tab 10 ' and the rail 6 is provided, a lifting of the role 5 from the track of the rail 6 allows.

In 12 is the fitting 2 ' shown in an exploded view. The lifting protection 11 ' is bar-shaped with an angled flap 10 ' educated. In a slot 18 ' is a bolt 15 ' stored, which is also for storage of the connecting element 14 ' serves. The connecting element 14 ' is also on the lever 12 ' coupled, so that when pivoting the lever 12 ' the lift-out protection 11 ' can be raised or lowered. The lever 12 ' can be locked in the first and / or second position.

To raise or lower the lift-out also other actuation mechanisms can be used. For example, a toggle mechanism can be used.
