Pivoting sliding door fitting for a piece of furniture

The invention relates to a pivoting-sliding door fitting according to the preamble of claim 1.

Pivoting sliding doors are well-known for furniture, where the door leaf can be pushed into the furniture body when opened, so that the opened door does not protrude from the furniture in a disturbing way. Such pivoting sliding doors are primarily used for TV cabinets, but can also be used for other cabinet compartments. In the well-known pivoting sliding doors, the door leaf is connected via hinges to a sliding plate, to which carriages are attached. These carriages carry rollers that roll in C-shaped guide rails attached to the furniture side. Each carriage has three rollers arranged one behind the other, with the middle one

Roller The height of its axis of rotation is offset from that of the outer rollers. For example, the outer rollers run on the lower bend of the C-shaped guide rail, while the middle roller rolls on the upper bend of these guide rails. Although this arrangement of the rollers ensures a certain parallel guidance of the carriages on the guide rails, the necessary play and the flexibility of the roller material mean that the door, ie the door leaf with the sliding plate, tilts around a horizontal axis, so that the door leaf hangs down due to its weight and drags on the floor of the furniture compartment. This can cause damage to the door leaf and the floor of the furniture compartment. In addition, if the two carriages are not guided parallel, there is increased wear on the rollers.

The invention is based on the object of creating a pivoting sliding door fitting of the type specified in the preamble of claim 1, in which tilting movements of the carriages are avoided, so that an exact parallel guidance of the sliding door is guaranteed.

This object is achieved according to the invention with the feature specified in the characterizing part of claim 1.

In the case of the pivoting sliding door fitting according to the invention, the carriages are not guided exclusively by the rollers, but the carriages also have guide pieces that engage the outside of the guide rail, i.e. on the top or bottom

side. While the rollers run inside the guide rail, the guide piece grips the guide rail from the outside, thereby ensuring better stability and exact parallel running even when the door leaf is very heavy. This prevents grinding marks on the shelf of the furniture and extends the service life of the rollers.

Preferably, the guide piece has a plastic guide rail that extends over all rollers. This guide rail rests essentially over the entire length of the carriage on the top or bottom of the guide rail.

The features of claims 3 and 4 improve the running behavior of the carriages and the parallel guidance. It also ensures that the same carriage can be used in conjunction with the upper guide rail as well as with the lower guide rail and for right and left hinged doors. Only one type of carriage is therefore required.

In the following, an embodiment of the invention is explained in more detail with reference to the drawings.

When the door leaf 18 is swung open,

it is located in a common plane with the

This is possible when the sliding plate 16 is located at the front end of the sliding path in which the lower carriage 15 hits the stop 20.

Each carriage 15 has a flat plate 22 which is screwed to the outside of the sliding plate 16. Near the lower end of the plate 22, three axles 23, 23a protrude horizontally outwards from the plate. The plastic rollers 24, 24a are mounted on the axles 23, 23a, with the middle axle 23a with the middle roller 24a sitting slightly higher than the two outer axles 23 with the outer rollers 24. The rollers 24, 24a, which run in a common plane, run in the C-shaped guide rail 14, with the outer rollers 24 rolling on the lower bend 14a, while the middle roller 24a rolls in the upper bend 14b of the guide rail.

The guide piece 25 is attached to the plate 22 above the rollers 24, 24a. This guide piece 25 has an elongated guide bar 26, which rests from above or outside on the upper bend 14b of the guide rail 14 and runs along the guide rail. The smallest distance between the circumferential surface of the roller 24a and the underside of the guide rail 26 is equal to the thickness of the material of the guide rail 14. This distance can also be slightly smaller so that the guide rail 26 against the top of the guide rail 14. The guide rail 26 extends over almost the entire length of the carriage 15, i.e. over the length taken up by the rollers 24, 24a.

As can be seen from Figures 4 and 5, the Guide rail 14 in the immediate vicinity of the shelf

At the end of the sliding plate 16, the relevant carriage 15 is mounted in the opposite direction, i.e. the rollers 24, 24a are located at the upper end of the carriage, while the plate 22 extends downwards. The guide piece 25 engages the upper guide rail 13 on the underside. In the upper carriage 15, the axis 23a of the middle roller 24a is slightly lower than the axes 23 of the outer rollers 24. The carriages 15 that interact with the upper guide rail 13 and the lower guide rail 14 are completely identical to one another. Only one type of carriage is therefore required. The same carriage can also be used if the pivoting sliding door is not attached to the left end of the furniture compartment, as in the embodiment shown, but to the right end.
