Description

Fitting for a sliding door

The present invention relates to a fitting for a sliding door, in particular for furniture, with at least one roller, which is rotatably mounted on a holder, wherein the holder relative to a fixable on a sliding door

Mounting plate is slidably mounted, and an at least partially effective in the vertical direction adjustment mechanism to align the vertical position of the mounting plate relative to the holder. The US 3,512,209 discloses an adjustment mechanism for a carriage of a sliding door, in which an axis of a roller is guided in an obliquely arranged slot. The elongated hole is formed in a slide which can be moved in the horizontal direction by means of a screw, so that the height of the roller can be adjusted relative to a housing surrounding the slide by moving the slide. It is problematic to couple the housing of the adjustment device with a self-closing or a stop, because the housing is adjusted relative to the roller in height, so that a fixed to a furniture body stopper or self-closing can be poorly connected to an activator , which is mounted on a height-adjustable housing.

It is therefore an object of the present invention to provide a fitting for a sliding door, which allows height adjustment and can be coupled in a simple manner with a self-closing or a stop.

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

According to the invention, at least one activator which can be brought into engagement with a self-closing mechanism and / or stopper is fixed to the holder or the adjusting mechanism. As a result, the fitting not only cause a height adjustment of a sliding door on a furniture body, but at the same time also other functions when closing and opening the sliding door, the activator with a self-closing and / or a stop or a locking element can be coupled. This makes it possible to provide the sliding door depending on the purpose with a corresponding fitting, which is then coupled with other functional parts, such as the self-closing or the stop. This allows a compact design with only a few components. According to a preferred embodiment of the activator remains at a height adjustment by the adjusting rigid to the holder or the adjusting mechanism, so that the activator remains relative to the furniture body at the same height. This allows exact positioning of the actuator relative to a driver of a self-closing mechanism or a stop.

Preferably, the activator is slidably mounted on a mounting plate. The activator may comprise a projection which can be coupled to a driver of a self-closing and / or stop, wherein the activator is fixed as a plastic component or metal component to the holder or a component of the adjusting mechanism.

In the fitting, preferably, the roller is movably mounted on the holder on a rail and on the adjusting mechanism, a fixed to the mounting plate door element is adjusted in height. In this case, an inventive fitting can be mounted on opposite sides of a door element in each case, so that in addition to a height adjustment and a tilt adjustment of a door element is made possible. The adjusting mechanism comprises in one embodiment a plurality of pins which are slidably mounted in slots. As a result, a stable leadership can be guaranteed, which can move heavy door elements.

In a particularly compact design of the holder on the mounting plate for height adjustment is slidably mounted obliquely to the vertical and horizontal. Then, the holder can be performed directly on the mounting plate, wherein the height adjustment is made by moving obliquely to the vertical and horizontal. The adjusting mechanism may comprise a threaded rod which is rotatably mounted on a threaded sleeve or nut and shifts the holder relative to the mounting plate. As a result, the height adjustment can be done very accurately. The threaded rod can have a groove into which a bent edge of the holder or the mounting plate is at least partially inserted. The threaded rod is thereby rotatably mounted on the edge, but not axially displaceable. As a result, a relative displacement of the mounting plate to the holder can be achieved by turning the threaded rod. According to a further embodiment, an intermediate plate is provided between the holder and the mounting plate, by means of which the holder is displaceable relative to the mounting plate. By forming an intermediate plate, the adjusting mechanism can be formed so that the intermediate plate is displaceable relative to the mounting plate and further the intermediate plate is displaceable relative to the holder, so that the mounting plate is displaceable relative to the holder substantially in the vertical direction. As a result, the roller moves only in a vertical direction during a setting process, so that a lateral displacement does not take place.

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

Figures 6A to 6E show several views of a modified embodiment of a fitting according to the invention.

On a furniture body 1, for example a cabinet, a sliding door 2 is movably mounted. For this purpose, a fitting 3 is mounted on the sliding door 2, which comprises a roller 4, which is movable on a rail 5. The roller 4 is rotatably mounted on a holder 6. The holder 6 is held on the sliding door 2 via a mounting plate 7. The fitting 3 comprises a rod-shaped activator 8, which can be brought into engagement with a driver of a self-closing mechanism 9, which is fixed to the body 1. Such Selbsteinzüge 9 with movable carriers are known per se and are therefore not explained in detail.

In Figure 2, the fitting 3 is shown on a sliding door 2, wherein the activator 8 can not be brought into engagement with a self-closing 9, but with a stop 10. The stopper 10 comprises two bendable spring arms, so that the activator 8 at the stop 10 can be locked. Via the activator 8 is thus possible to couple with other components, such as a self-closing 9, a stop 10, a damper or other components that are fixed to an upper side of the body 1 adjacent to the rail 5.

In the figures 3A to 3E, the fitting 3 is shown in detail. The roller 4 is rotatably mounted about an axis 1 1, which is fixed to the holder 6. The holder 6 is made of a bent and stamped sheet metal and has a substantially U-shaped contour, wherein at a bottom portion of the

Roller 4 is fixed and laterally projecting edges 12 are formed. At each edge 12, an outwardly open slot 13 is formed.

The slot 13 serves for connection to an adjusting mechanism, which comprises a threaded rod 16. On the threaded rod 16 two discs 15 are fixed, which form a groove 14 between them, in which the material of the edge 12 is partially inserted. As a result, the threaded rod 16 is indeed rotatably mounted on the edge 12, but not axially displaceable. Furthermore, the threaded rod 16 is carried out on a threaded sleeve 18, which comprises an internal thread and is connected to the activator 8. The threaded rod 16 includes at its end a head portion 17 with a tool insert, so that the threaded rod 16 can be rotated via the engagement of a tool.

The threaded sleeve 18 is fixed to a component 38, on which two openings for performing a pin 19 are formed.

As is apparent from Figures 3B and 3E, the pins 19 are performed by the component 38 and the mounting plate 7, wherein on the mounting plate 7 vertical slots 22 are recessed, through which the pins 19 are performed.

In a central region of the mounting plate 7, three elongated holes 21 are further recessed, in each of which a pin 20 engages. The elongated holes 21 are arranged inclined at an angle α to the horizontal, which, for example, in an is aligned in the range between 10 ° and 40 °. At the pin 20 of the holder 6 is fixed, which is movable together with the pin 20.

The mounting plate 7 further includes openings 23 for fastening means, so that the mounting plate 7 is fixed to a rear side of a sliding door 2. In order to prevent displacement of the mounting plate 7 after assembly, further protruding tips 24 are formed, which project from the back of the mounting plate 7 and are hammered into the material of the sliding door 2. The mounting plate 7 is symmetrical with respect to the vertical elongated holes 22 to a middle vertical plane, while the holder 6 is also formed symmetrically to a central vertical plane, so that the fitting 3 for both the right and the left side of a Sliding door can be used. For an adjustment, the threaded rod 16 is rotated via a tool. Characterized the holder 6 is moved relative to the mounting plate 7 along the obliquely oriented slots 21. The threaded rod 16 remains aligned horizontally, since although the distance between the holder 6 and the component 38 changes, but not their altitude relative to each other. The holder 6 is displaced together with the component 38, which is guided along the vertical elongated holes 22. As a result, the activator 8 is arranged at the same height relative to the roller 4. Only the horizontal distance between the roller 4 and the activator changes, but this is irrelevant to the opening and closing operation of the sliding door 2.

A modified embodiment of the fitting is shown in FIGS. 5A and 5B. While the fitting of Figures 3A to 3E can be used only for rear sliding doors, the fitting of Figures 5A and 5B can also be used for middle or front sliding doors. For this purpose, an angle 30 is provided, which is fixed to a middle or front sliding door via fastening means. On a protruding leg 31, a holder 32 is fixed to the mounting plate 7. On the mounting plate 7, a holder 6 is then held with the rotatable roller 4. The holder 6 is displaceably mounted on the mounting plate 7 via an adjusting mechanism, as has already been explained with reference to FIGS. 3A to 3E. The distance between the mounting plate 7 and the vertical portion of the angle 30 is selected so that one or more sliding doors 2 can be overlapped. A modified embodiment of a fitting 3 'is shown in FIGS. 6A to 6E. The fitting 3 'comprises a mounting plate 7' and a holder 6 ', wherein on the holder 6' an axis 1 1 'is fixed, on which a roller 4' is rotatably mounted. On the plate-shaped holder 6 ', a component 80 is fixed, on which a peg-shaped activator 8' is held. At the bottom of the component 80, a U-shaped receptacle 81 is formed, which engages over a rail 5 on an upper side of a furniture body 1. Thereby, it can be prevented that the holder 6 'can be moved only in the longitudinal direction of the rail 5.

Between the holder 6 'and the mounting plate 7', an intermediate plate 40 is arranged. In the intermediate plate 40 three oblique slots 41 are recessed, which are aligned at an angle between 10 ° and 30 ° to the horizontal. The slots 41 are penetrated by pins 42. The pins 42 also pass through vertical slots 48 which are formed on the mounting plate 7 '.

The intermediate plate 40 has on opposite sides protruding edges 43 which have a slot through which a threaded rod 44 is performed. The threaded rod 44 is rotatably mounted on a projection 47 of the mounting plate 7 ', wherein between a head 46 of the threaded rod 44 with a tool insert and a groove, the threaded rod 44 while rotatably, but not axially displaceable on the mounting plate 7' is held. Furthermore, 44 two discs 45 are provided with an internal thread, between which the edge 43 of the intermediate plate 40 is held on the threaded rod. By rotating the threaded rod 44, the intermediate plate 40 can thus be displaced in the horizontal direction relative to the mounting plate 7 '. It is of course possible, instead of the threaded rod 44 to provide other adjustment mechanisms to achieve a horizontal displacement. In addition, the threaded rod 44 can be fixed in the axial direction of the intermediate plate 40 and reach by rotating a displacement of the mounting plate 7 '.

When the threaded rod 44 is rotated, move between the intermediate plate 40 and the mounting plate 7 'in the horizontal direction relative to each other, so that the pins 42 which are guided in the slots 41 and 48, move in the vertical direction. At the pin 42 of the holder 6 'is fixed, which is thereby displaced together with the pin 42 in the vertical direction. The adjusting mechanism is designed so that the mounting plate 7 'and the holder 6 'in the horizontal direction are not moved relative to each other, but only in the vertical direction.

On the mounting plate 7 ', a pin 51 is further formed, which is guided in a vertical oblong hole of the holder 6' or of the component 80. Since the component 80 is fixed to the holder 6 ', no height adjustment of the activator 8' takes place relative to the roller 4 '.

In the embodiments shown, the holder 6, 6 ', the mounting plate 7, 7' and the intermediate plate 40 are made of a stamped or bent metal sheet. It is of course possible to provide other materials and components for a fitting according to the invention. In addition, the adjustment can be modified, because instead of a threaded rod 16 and 44 and other adjustment can be used medium.
