Hardware for a sliding door

The present invention relates to a fitting for a sliding door, with a rail, along which at least one piece of rolling rests, and an automatic retractor with a movable drag stop along a sliding guide , which is coupled to an activator disposed in the race to move the race to a terminal position.

Publication DE 10 2011 050 394 A1 discloses a fitting according to the preamble of claim 1.

Publication DE 20 2009 014 882 discloses a fitting for a sliding door, in which an activator is installed in a rolling part, which can be coupled to a closing aid. In this case, the activator can be embedded in a sheave support. In this way it is possible to install without activators the activators in the roller support.

In publication DE 10 2011 050 394 a fitting for a sliding door is shown in which an activator is provided in a rolling part which can be engaged with an automatic retractor. In this case, the activator is fixed on the tread so that it is adjustable so that a tolerance adjustment can be made easily. However, numerous construction parts are required for the rolling part. In addition, in a sliding door fitting, separated from the activator, a retainer is almost always mounted in order to prevent a sliding door from a rail from being raised without intention. When installing the sliding door hardware, a large number of construction parts have to be installed and adapted, mainly if rolling parts are used on the right and left on a sliding door.

Therefore, it is the object of the present invention to develop a fitting for a sliding door which has a simple structure and makes easy installation possible.

This object is achieved with a fitting according to the characteristics of claim 1.

According to the invention, the activator is able to move relative to a support of the raceway from a mounting position in at least one functional position, in which a coupling can be made with the trailing stop of the automatic retractor, in which In case the activator in the mounting position makes it possible to mount the tread on the rail, but in a functional position the tread is secured against the lifting of a rail by means of a stop on the activator. In this way, with the activator, a retainer is thus provided that prevents the lifting of the rail rolling part, at least to the extent that the rolling part can be removed from the rail.

In addition to the function of the retainer, the activator is capable of being coupled to a functional position with an automatic retractor which moves the sliding door with the activator to a predetermined final position. In this case, the automatic retractor can prestress the trailing stop in a final position by means of a spring, in which case a damper can also be provided in the automatic retractor. In this way, the hardware for a sliding door with few structural parts can have high functionality.

In accordance with the invention, the activator rests on the support of the tread so that it is able to rotate or move so that a movement from the mounting position to the functional position can be made or vice versa. In this case, the movement of rotation and / or displacement is carried out respectively without a tool. This is very advantageous together with the possibility of installing the activator on the sliding door before it is mounted and leaving it permanently there, both during assembly and also in the disassembly of the sliding door furniture.

According to the invention, the activator has a projection that can be engaged with an outlet in the trailing stop of the automatic retractor. The projection can project essentially vertically in a direction of a plate-shaped support of the tread so that a compact type of construction is obtained. In addition, the projection can be arranged at a distance from the stop against the lifting of the rail.

For a simple manufacture of the hardware with few construction pieces, the activator can be manufactured in one piece, mainly of plastic or metal. Particularly advantageous are plastic and soft component assemblies such as, for example, a plastic-rubber assembly (P&C assembly).

In addition, the activator can be embedded in the mounting position and / or in a functional position to prevent a detachment by mistake after a movement of the activator in the functional position. The recessing is carried out here by means of functional elements that have a drag and / or blocking effect, which are formed directly or indirectly in the activator and the tread.

Preferably, the activator is capable of moving from the mounting position in two functional positions

different. In this way, right and left rolling parts can be prevented, that is, rolling parts that are mounted on the right side or on the left side of a sliding door. Two rolling parts of the same type can be installed on the right and left side of a sliding door, in which case, only by means of the movement of the activator in the corresponding functional position is it established whether it is a right or left structural part. This saves storage costs and simplifies assembly.

In order to provide high damping forces, two activators that interact respectively with an automatic retractor can be provided on the race. In this case, the automatic retractor can have a shock absorber, so that very heavy sliding doors can also be moved with the hardware of the invention. Alternatively, a first activator can direct an opening damping while a second activator directs a closing damping. In this case, the various activators and dampers may be arranged at one level, but also at different levels. Even a mounting with more than two automatic activators and retractors or dampers is conceivable.

The invention is explained in more detail below by means of several embodiments with respect to the attached drawings. In these:

Figure 1 shows a perspective view of a piece of furniture with the hardware for a sliding door according to the invention;

Figure 2 shows a side view through the furniture of Figure 1;

Figure 3 shows a side view through the furniture of Figure 1 in a modified embodiment;

Figures 4A and 4B show two views of the hardware of Figure 2 with different positions of the activator;

Figures 5A to 5C show several views of the hardware of Figure 2;

Figures 6A to 6D show several views of the hardware of Figure 5;

Figures 7A and 7B show two views of a hardware of Figure 5 in a modified embodiment; Figures 8A to 8C show views of a hardware in a modified embodiment, and Figures 9A to 9D show views of a hardware in another embodiment.

A cabinet cabinet 1 comprises a cabinet body 2, in which a rail 3 is fixed, to place several rolling parts 4 of a fitting for a sliding door so that they can move. The rolling parts 4 can interact with an automatic retractor 5 in a terminal position, to run the sliding door to a terminal position. The automatic retractor 5 can also provide a corresponding damping in the opening or closing direction.

Figure 2 shows the hardware in a side view. The rail 3 is fixed in an upper layer 20 of the body of the furniture 2 with an upper horizontal arm 30. On rail 3, two U-shaped tracks 31 and 32 are formed for roller sheaves 9. Of course, it is also possible that rail 3 has only one track or more than two tracks to guide the roller sheaves 9.

The automatic retractor 5 comprises a housing 6 that is fixed on a rail of the furniture body 2. In the housing 6 a movable drag stop 7 is provided that can move along a sliding guide and transmits corresponding opening forces, of closing and / or damping to an activator 8, which is fixed in a race piece 4. The race part 4 is fixed here on the rear side of a front plate 60 of a sliding door, in which case for each plate front 60 two raceways 4 are provided spaced apart from each other. The quantity and position of the rolling parts 4 can be selected depending on the weight of the front plate 60.

A modified embodiment of a hardware is shown in Figure 3 in which, as a complement to the embodiment shown in Figure 2, another automatic retractor 5 'is provided, which has a housing 6' in which a drag stop T so that it can move. In turn, the trailing stop T can be moved along a sliding guide and prestressed by means of a spring in a starting position. In addition, a shock absorber can also be positioned in the automatic retractor 5 'so that the front plate 60 can be braked or accelerated by the tread 4 by means of two automatic retractors 5 and 5'. Precisely, therefore, in the case of heavy faceplates 60, a larger retraction force or a larger damping force can be generated.

Figure 4A shows the hardware of Figure 2 in a mounting position. The activator 8 comprises a projection 80 protruding from the level of the front plate 60 in an essentially vertical position, in which case the activator in the mounting position is directed downwards. The activator 8 rests here in such a way that it can rotate around an axis 83, and in a mounting position, between an upper surface 84 and a lower side of the rail 3, a slit L is present which makes it possible to raise the race piece 4 with the front plate 60. The slit L is a vertical section of a side wall 33 that delimits the track 32. In this way, in order to disassemble the front plate 60, the roller bearing 9 can exit the track 32 and move along the side wall by lifting the front plate 60.

Figure 4B shows the hardware of Figure 4A in a functional position.

The activator 8 was rotated approximately 90 °, so that the projection 80 is no longer positioned below the axis 83, but essentially at the same height as this. In this position, the projection 80 of the activator 8 can be engaged with a drag stop 7 of an automatic retractor, as shown in figure 2. By turning the activator 8, a stop 85 is arranged below the rail 3, which is arranged on rail 3 closer than surface 84. In this way, a slit 88 results between the lower side of the runway 32 and the stop 85 which is smaller than the height of the side wall 33 on the rail 3 and, by therefore, smaller than the slit L. In this way a lifting of the front plate 60 in which the roller bearing 9 can be removed laterally by the side wall 33 is prevented, so that the stop 85 serves as a retainer .

In Figures 5A to 5C, the rolling part 4 of the hardware of Figure 2 is shown in detail. The tread 4 comprises a plate-shaped support 40 on which a fastener 41 is mounted. Between the fastener 41 and the plate-shaped support 40 rests a roller bearing 9 so that it can rotate, in which case on the support 40, if necessary, several sheaves with bearing 9 can also be provided. Below the sheave with bearing 9 is the activator 8 located so that it can rotate, which is shown in a position assembly in figure 5A. From this mounting position the activator 8 can optionally rotate clockwise or counterclockwise, in order to get into a functional position. In FIG. 5b, the activator 8 rotates clockwise so that the projection 80 can now engage with the drag stop on the right side of the support 40. The activator 8 therefore rotates up to a stop 86 in the support. 40, which is formed by a relief. Alternatively, the trigger 8 can also rotate clockwise, as shown in Figure 5C. The activator is now directed to the left and the projection 80 is arranged on the left side of the support 40. In this the activator 8 can be embedded in the functional positions of Figures 5B and 5C, so as to ensure a stable placement. By turning the activator 8, it is established whether the rolling part 4 is a right or left rolling part, so that the rolling parts 4 of the same type can be distributed and only during assembly it is decided whether it is a construction piece right or left.

In Figures 6A to 6D the hardware of Figure 5 is shown in detail. The activator 8 comprises an undercut socket, into which a mushroom-shaped bolt 82 or a rivet can be inserted. The bolt 82 comprises an enlarged head section, such that removal of the activator 8 by the plate-shaped support 40 can be prevented. This increases the stability of the activator 8 and reduces the load on the axis 83 of the center. The shaft 83 can also be configured as a mushroom-shaped bolt or rivet to position the activator 8 so that it can rotate on the support 40. In this, on a opposite side a mushroom-shaped bolt 82 is fixed on the support 40, which may or may not be engaged with the corresponding socket depending on the rotation movement of the activator 80.

Figure 6D shows the stop 86 in the plate-shaped holder 40 in detail, which is configured as an embossment and forms a stop for the activator 8. Furthermore, it can be seen that the activator 8 has a channel for housing the 82 mushroom bolt. In the channel a spring bar 87 can be provided at rest to engage the activator 8 in a functional position and prevent unintended loosening.

A modified embodiment of a hardware is shown in Figures 7A and 7B, which essentially corresponds to the hardware shown in Figures 5 and 6. Instead of a mushroom-shaped bolt 82, in the shaped holder 40 The plate is provided with an outwardly inclined gasket 92, in which an opening 94 is formed. The activator 8 is embedded in the gasket 92 instead of the mushroom-shaped bolt 82, in which case, for this, a button a pressure 93 is engaged in the opening 94. Otherwise, the fitting corresponds to the preceding embodiment.

In Figures 8A to 8C another embodiment of a hardware is shown in which, in the plate-shaped support 40, a stopper 86 is provided, in which the activator 8 can be placed. The activator 8 is also located in a functional position beyond the plate-shaped support 40, such that an edge 103 fits into a front edge of the plate-shaped support 40. In this way, the stability of the activator 8 can be further increased. Moreover, the rolling part 4 corresponds to the preceding embodiments.

In Figures 9A to 9c another example of embodiment of a rolling part of a hardware according to the invention is shown. The tread comprises a plate-shaped support 40 on which rests, so that it can rotate, a roller bearing 9. Instead of an activator capable of rotating, a movable activator 10 is provided, which can move along a curvilinear guide. For this, two mushroom-shaped bolts 13 are fixed in the plate-shaped support 40, which are respectively engaged in a sliding guide 11. In this way two sliding guides 11 are formed in the activator 10, which have a section 12 flexed. In the activator 10 a projection 14 is formed that projects vertically from the plane of the front plate 60, and the projection can be engaged with a socket in a trailing stop 7.

Figure 9D shows the activator 10 in a mounting position. In this position the roller bearing 9 can be hung on a rail 3, on a top layer 20. As soon as the assembly is carried out, the activator 10 can

move along the mushroom-shaped bolt 13 until the position shown in Figure 9A is reached. The activator 10 was moved in such a way that now, below the roller sheave 9, only one stop 15 of the activator 10 is provided, which prevents a lifting of the tread. In such a case, a spring 16 compresses the activator 10 downwards to prevent unintended loosening of the activator 10 from the functional position. By means of the spring 16, the mushroom-shaped bolts 13 are kept closed in a flexed end section 17. The closed terminal section 17 is formed only on the left slide guide 11, although it would also be possible to provide such a closure even on the right slide guide 11. If the tread must be detached from rail 3, the activator 10 must first move along the slide guide 11 to then lift the roller bearing 9 accordingly and be able to raise it from rail 3.

The plate-shaped support 40 of the tread piece 4, in the exemplary embodiments, can be manufactured from a die-cut and folded metal sheet.

In the exemplary embodiments shown, the activators 8 rest so that they can rotate or move. Of course, it is also possible to opt for other mechanisms to move the activator in order to bring it from a mounting position to a functional position.

In addition, the field of employment of the hardware is not limited to furniture; Sliding doors or corresponding sliding parts can also be used in household appliances or in other sectors.
