Description

Fitting for at least one linearly movable sash and furniture

The present invention relates to a fitting for at least one linearly movable wing, in particular for furniture, with a guide rail which can be fixed on at least one holder on a body, wherein the holder and the guide rail are at least partially positively engageable in engagement, and also a piece of furniture with such a fitting.

EP 838 572 discloses a sliding fitting for doors or windows, in which a running rail is fixed over a plurality of holding elements. The holding elements are designed as fastening clips, which have bendable fastening flaps, which are engaged behind by projections on the running rail. This simplifies the mounting of the track, which is then pushed onto the mounting clips. In the locking of the running rail is disadvantageous, however, that the attachment tabs can absorb only limited forces, since they consist of a bendable material and can break under heavy load. In addition, the rail is not locked in the longitudinal direction.

It is therefore an object of the present invention to provide a fitting for at least one linearly movable wing, which is easy to assemble and allows stable attachment of the guide rail.

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

In the fitting according to the invention, a stop element is indirectly or directly fixed to the guide rail, which secures the guide rail in the direction of travel of the wing. This allows the guide rail to be secured against displacement in the direction of travel of the linearly movable wing on the holder, which improves the positioning of the guide rail. Preferably, a stop element is provided with two stops on the guide rail, wherein the stops surround the holder, in particular engage around substantially form fit, so that the guide rail is secured against movement in the direction of travel of the linearly movable wing. According to a further aspect of the invention, the fitting comprises a holder on which a guide rail can be fixed, wherein on the holder a movable securing element is guided, which is movable from a mounting position to a securing position and secures the guide rail to the holder in the securing position. As a result, the guide rail can be positively secured to the holder when loaded. It can thereby be achieved that the guide rail no longer has degrees of freedom in the three spatial directions. In addition, it can be prevented that bendable locking webs are loaded. The securing element can secure the guide rail in the mounting position against movement out of the mounting position, wherein the guide of the securing element can be made stable, so that a higher load capacity of the connection between the guide rail and holder is ensured. Furthermore, a simple disassembly is made possible by the securing element.

Preferably, the securing element is displaceably mounted on the holder. In this case, one or more guideways may be formed on the holder, along which the securing element is displaceable. In this case, the guide rail can be plugged onto the holder in a first direction and the securing element can be moved in a second direction relative to the holder, which is aligned at an angle to the first direction, preferably at right angles. As a result, it is possible to prevent removal of the guide rail in the first direction, with the forces for removing the guide rail acting at an angle on the securing element, in particular at right angles, so that high holding forces can be provided.

For ease of assembly, the securing element can be latched in the securing position. Additionally or alternatively, the securing element can also be latched in the assembly position, so that a pre-fixing of the securing element to the holder is possible.

For a stable attachment of the holder this can be formed angular. In this case, both legs of the holder can be screwed to the carcass or be otherwise determined indirectly on the body. Conceivable also projections formed on the holder, such as round-shaped

Pins that engage in corresponding openings on the body and thus clearly position the holder. In order to load the guide rail in different loading directions and to absorb the forces through the holder, the securing element in the securing position with a securing portion can engage behind a web of the guide rail. In the securing position, a web of the holder can be encompassed in a U-shape by a section of the guide rail or a web of the guide rail U-shaped by a holder, so that a good power transfer is possible.

The fitting according to the invention can be used in particular for furniture, in particular cabinets with linearly movable wings, but also for use with linearly movable wings for room dividers or windows is possible. Under movable wings are linearly movable wing elements such as sliding doors, folding sliding doors, rotary sliding or sliding doors or the like to understand. The term guide rail also includes rails on which load-bearing elements such as rollers or sliding elements are guided.

The invention will be explained in more detail below with reference to an embodiment with reference to the accompanying drawings. Show it:

The guide rail 10 is fixed to holders 6, which are fixed to the bottom 5 and a vertical wall section 8 below the bottom 5. Over the length of the guide rail 1 0 while a plurality of holders 6 are provided, wherein on each holder 6, a securing element 7 is slidably mounted. Guide rails and load-receiving carriages are provided in the upper region of the cabinet furniture for guiding the sliding doors 3 and 4, and in the lower area the guide rail 10 serves for guiding the sliding doors 3 and 4 on the bottom. The guide rail 10 has two adjacent grooves 1 for this purpose 1 and 1 2, on which the movable in different planes sliding doors 3 and 4 are guided.

In an X, Y, Z coordinate system, the X coordinate symbolizes the depth direction, the Y coordinate the traversing direction of the linearly movable sash, here a sliding door, and the Z coordinate the height direction.

In FIGS. 3A to 3C, the mounting of the guide rail 10 on the holder 6 is explained: In FIG. 3A, the guide rail 10 is shown at a distance from the holder 6. The guide rail 1 0 has on the groove 1 1 a groove bottom 1 3, which can be applied to the underside of the bottom 5. The adjacently arranged groove 1 2 is arranged less deep than the groove 1 1 and has a groove bottom 14 which is positioned at a distance from the bottom 5. Adjacent to that

Groove bottom 14 is formed on the side facing the bottom 5 a web 1 7, which is brought into engagement with the holder 6. Adjacent to that

Slot groove 14 is a groove 22 which serves for mounting a Anschlagele- mentes 9 with two stops 60, which is determined for example by screws on the guide rail 10. The open side of the groove 1 2 is at least partially closed by inwardly projecting webs 1 6.

The guide rail 10 further comprises a vertical portion which can be fixed to a vertical leg 40 of the holder 6. For this purpose, a groove 1 8 is formed on the guide rail 1 0 with an undercut forming web 21.

When sliding the guide rail 1 0 reaches the web 31 in the receptacle between the web 1 7 and the groove bottom 14 of the guide rail 1 0. At the web 31 an upwardly directed projection 32 is provided which serves as a stop and the leg 30 at the Bottom of bottom 5 is supported. In this case, the securing element 7 is in a

Pre-locking position, which corresponds to a mounting position.

When the guide rail 1 0 is pushed horizontally in the X coordinate direction on the holder 6, the position shown in Figure 3C is reached. After the guide rail 10 has reached its end position in the X coordinate direction, the securing element 7, guided on the holder 6, can be moved vertically in the Z coordinate direction. Here, a web 71 of the securing element 7 is inserted into the groove 1 8, which is formed on a groove wall 1 9 of the groove 1 2. At the groove 1 8 is a projecting into the groove 1 8 at the top

Web 21 is provided, which extends in the vertical direction downwards. When the securing element 7 is displaced upwards on the holder 6 in the vertical direction, the web 71 engages behind the web 21 on the guide rail 10 and thus secures the guide rail 10 against horizontal withdrawal in the X-coordinate direction. In the direction of travel of the linearly movable wing, the guide rail 1 0 is secured by a stop element 9 with stops 60 which surrounds the holder 6.

FIG. 4 shows how guide elements arranged on the sliding doors 3, 4, in this case in the form of rollers 50, interact with the fully assembled guide rail 10. In the groove 1 1 is a roller 50 or a slider to guide one of the rear sliding doors 4. For this purpose, a guide holder 52 is fixed to the rear sliding doors 4, on which the roller 50 is rotatably mounted and is guided on vertical groove walls of the groove 1 1. Similarly, the front sliding door 3 is connected to a guide holder 51 which rotatably supports a roller 50 which is guided in the groove 1 2 in the lateral direction, wherein forces are transmitted from the rollers 50 to the guide rail 1 0 and the holder 6 , In FIGS. 5A and 5B, the holder 6 and the securing element 7 are shown in exploded perspective views with the front and rear side views. The holder 6 comprises a horizontal leg 30, on which a protruding web 31 is formed, which can be inserted into a U-shaped receptacle of the guide rail 10. On a vertical leg 40, a recess 41 is provided which forms guide strips 42 for the securing element 7 on opposite side walls. The securing element 7 is inserted into the recess 41 and has on opposite sides projections 74, which are guided on the guide rails 42. On opposite sides in each case a resilient latching web 72 is formed, which has a latching projection 73. The latching projection 73 can engage in latching receptacles 44 and 45, which are formed on the vertical leg 40 of the holder 6. The securing element 7 further comprises, in addition to the horizontal web 71, a second parallel web 70, which form a U-shaped receptacle between them and form a wall section of the vertical leg 40 in the view of FIG. encompassing approximately position, so that at transverse forces on the web 71 of the web 70 transfers holding forces on the holder 6. The securing element 7 also comprises on the lower side an actuating portion 75 with a tool holder, so that the securing element 7 is displaceable from a mounting position into a securing position.

Furthermore, it is shown in FIGS. 5A and 5B that the holder 6 has openings 46 for fastening screws on the vertical leg 40 and also an opening 46 for a fastening screw is provided on the horizontal leg 30. For ease of assembly are instead of openings on the holder 6 integrally formed projections, for example in the form of round-shaped pins or dowels, conceivable that engage in corresponding openings on the body. These could also be hollow to accommodate fasteners such as screws or nails can.

Further, the holder 6 comprises on the vertical leg 40 outwardly projecting arms 47, which come to rest on the wall portion 8. The arms 47 of those holders 6, which are fixed on the left and right at the peripheral positions of the wall section 8, serve as stop edges on the side wall 2. Next to the arms 47, a stop surface 49 is formed, which is provided with a stop for limiting the displacement in Movement direction of the wing, so in the Y coordinate direction, cooperates.

In FIGS. 6A to 6C and FIGS. 9A and 9B, the securing element 7 is arranged on the holder 6 in a mounting position. In this position, the latching projection 73 is arranged in the lower latching receptacle 44. The contour of this locking receptacle 44 is provided with a locking angle α, which is designed such that it assumes an angle equal to or about 90 ° and forms a horizontal leg of the locking receptacle 44, which lies approximately in the same line as the horizontal web of the fuse element. 7 trained latching projection 73. Thus, it is effectively prevented that after the first insertion of the securing element 7 in the holder 6 an unwanted, complete release of securing element 7 and holder 6 can be done. A further movement of the securing element 7 in the holder 6 from the lower mounting position to the upper securing position, however, is readily possible.

The securing position is shown in FIGS. 7A to 7C and FIGS. 8A and 8B. The fuse element 7 has been moved upwards in Z coordinate shifted, wherein the arranged on opposite sides latching projections 73 have been moved from the lower latching receptacle 44 into the upper latching receptacle 45 and engages the securing element 7 in the hedging position by the movement of the resilient latching webs 72 and the latching projections 73. The cogging forces are determined by the run-up bevels β, which are formed on the side walls 43 of the holder 6 between the latching receivers 44 and 45. The chamfers ß allow from a certain amount of force a further movement of the securing element 7 in the holder 6 from the upper securing position to the lower mounting position. The angle of the chamfers ß here is about 45 ° and is preferably in a range between 30 ° and 60 °.

In FIGS. 10A and 10B, the securing element 7 is located in front of the mounting position and is being pushed onto the holder 6.

As shown in Figures 1 1 A and 1 1 B, the holder 6 is first fixed by screws 48 by a screw 48 on the upper leg 30 and two screws 48 are screwed to the vertical leg 40 of the holder 6. The fuse element 7 is located during assembly in the lower mounting position. In this case, those holders 6, which are arranged on the left and right at the end edge positions of the wall section 8, are positioned so that the vertical edges of the arms 47 abut against the side walls 2.

In order to prepare the assembly, a stop element 9 is also fixed to the guide rail 10, as shown in FIGS. 12A and 12B. The stop element 9 comprises two stops 60, which are held together by a connecting rod 61. As a result, the distance between the two block-shaped stops 60 is predetermined. In each stop 60, a fastening opening 62 is formed into which a screw 63 can be inserted. The stop element 9 with the stops 60 is inserted into a groove 22 on the guide rail 10 and then fixed by the screws 63. Preferably, only one stop element 9 is required for the determination of the guide rail 10 on the body, which is optionally arranged on the left or right at the end edge positions of the guide rail 10.

Subsequently, the guide rail 10 can be fixed to the holders 6, as shown in Figures 13A and 13B, wherein the furniture body is not shown in these figures. The guide rail 10 is, as already written horizontally in the X coordinate direction on the holder 6 is pushed, so that a web 31 of the holder 6 is embraced in a U-shape. At the same time, the stop element 9 with the stops 60 is pushed around the holder 6, so that the stops 60 are positioned adjacent to lateral stop surfaces 49 on the holder 6. Here, the internal spacing between the stops 60 is equal to or slightly larger than the distance between the two lateral stop surfaces 49 to each other. By positioning the stops 60 on both sides of the holder 6, a movement of the guide rail 10 in the direction of travel of the sliding door can thus be prevented. After installation of the guide rail 1 0, the securing element 7 is displaced upwards into the securing position, so that the guide rail 1 0 is secured against removal. As a result, the guide rail 10 is thus effectively positively fixed in all three spatial directions (X, Y, Z) on the body and secured against unintentional movement.

In order to disassemble the guide rail 10 again, the securing element 7 can be moved out of the securing position, as shown in FIGS. 14A and 14B. A tool 80, in particular a screwdriver, engages with a tip in the operating portion 75 on the securing element 7 and pulls it down so that the web 71 is moved downward and the web 21 on the guide rail 1 0 releases. If in all holders 6, the securing element 7 has been moved down, the guide rail can be deducted 1 0 forward of the furniture body.

The holder 6 serve in cooperation with the securing elements 7 for a positioning of the guide rail, on the other hand, they are capable of forces that would otherwise be introduced into the side walls 2, record.

The fitting according to the invention with the holders 6 is used in particular in cabinet furniture. But it is also possible to use the fitting in other linearly movable wings, for example, for room dividers or windows.

In the illustrated embodiment, the securing element 7 is moved to the holder 6. Of course, it is also possible for the securing element 7 to be mounted pivotably on the holder 6. For example, the securing element can then be hook-shaped and a web of the guide ing rail 10 engage behind when the pivotable securing element is arranged in the securing position.
