Description

Fitting for a sliding door

The present invention relates to a fitting for a sliding door, with a rail along which at least one running part is movably mounted, and a self-closing with a movable along a guideway carrier which can be coupled with an arranged on the running part activator to the running part in an end position to move. DE 20 2009 014 882 discloses a fitting for a sliding door, in which an activator is mounted on a running part, which can be coupled with a closing aid. The activator can be locked on a roller carrier. This makes it possible to mount the activators without tools on the roller carrier.

In DE 10 201 1 050 394 a fitting for a sliding door is shown, in which an activator is provided on a running part, which can be brought into engagement with a self-closing. The activator is adjustably held on the running part, so that in a simple way tolerance compensation can be made. However, numerous components are required for the running part. In addition, a lift-off is usually mounted separately from the activator in a sliding door fitting so that unintentional lifting a sliding door is prevented by a rail. When mounting the sliding door fitting thus a variety of components must be mounted and aligned, especially when right and left runners are used in a sliding door.

It is therefore an object of the present invention to provide a fitting for a sliding door, which is simple in construction and allows easy mounting.

This object is achieved with a fitting with the features of claim 1. According to the invention the activator is movable relative to a support of the running part of a mounting position in at least one functional position, in which a coupling with the driver of the self-closing can be done, the activator in the mounting position allows mounting of the running part on the rail, but in a functional position the running part by a stop at the activator against a lifting of the rail secures. As a result, with the activator both a lift-out protection is provided, which prevents lifting of the running part of the rail at least as far as that the running part can be removed from the rail. In addition to the function of the anti-lift device, the activator can be coupled in a functional position with a self-retractor, which moves the sliding door with the activator into a predetermined end position. The self-retraction can bias the driver into an end position by a spring, optionally also a damper can be provided on the self-closing. As a result, the fitting for a sliding door with few components can have a high degree of functionality.

Preferably, the activator is pivotally mounted on the carrier of the running part. Alternatively, it is possible to displaceably mount the activator on the carrier of the running part in order to be able to move from the assembly position into the functional position or vice versa. In this case, the pan and / or sliding movement can be done without tools. This is in addition to the ability to attach the activator before the installation of the sliding door on this and to leave permanently on this, both during assembly and disassembly of the sliding door furniture very beneficial.

In one embodiment of the invention, the activator on a projection which can be brought into engagement with a receptacle on the driver of the self-closing. The projection may protrude substantially perpendicularly in a direction from a plate-shaped carrier of the traveling part, so that a compact construction is obtained. Further, the projection may be spaced from the stop against the lifting of the rail.

For a simple manufacture of the fitting with few components, the activator can be made in one piece, in particular of plastic or metal. Particularly advantageous are plastic soft component composites, such as a plastic-rubber composite (K & K composite).

Furthermore, the activator can be locked in the mounting position and / or a functional position to avoid accidental release after moving the activator into the functional position. The locking takes place here via force and / or formschlusswirkende functional elements that are formed directly or indirectly on the activator and the running part.

Preferably, the activator is movable from the mounting position into two different functional positions. This allows right and left Running parts are cutted, so run parts, which are mounted on the right or left side of a sliding door. Two identical running parts can be mounted on the right and left side of a sliding door, which is determined only by moving the activator in the associated functional position, whether it is a right or left component. This saves storage costs and simplifies assembly.

In order to be able to provide particularly high damping forces, two activators can be provided on the running part, each of which interacts with a self-closing mechanism. The self-closing can have a damper, so that even very heavy sliding doors can be moved with the fitting according to the invention. Alternatively, a first activator can control an opening attenuation, during which a second activator activates a closing attenuation. In this case, the plurality of activators and attenuations can be arranged in one plane, but also in different planes. An assembly with more than two activators and Selbsteinzügen or damping is conceivable.

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

Figures 7A and 7B are two views of a fitting of Figure 5 in a modified embodiment; Figures 8A to 8C are views of a fitting in a modified embodiment, and

Figures 9A to 9D views of a fitting in a further embodiment.

A cupboard 1 comprises a furniture body 2, on which a rail 3 is fixed in order to store several run parts 4 of a fitting for a sliding door movable. The runners 4 can cooperate in an end position with a self-closing mechanism 5 to pull the sliding door into an end position. The self-closing mechanism 5 can also provide a corresponding damping in the opening or closing direction.

In Figure 2, the fitting is shown in a side view. The rail 3 is fixed with an upper horizontal leg 30 to a top floor 20 of the furniture body 2. On the rail 3, two U-shaped raceways 31 and 32 are formed for rollers 9. Of course, it is also possible that the rail 3 has only one track or more than two raceways for guiding rollers 9.

The self-closing 5 comprises a housing 6 which is fixed to a rail 3 of the furniture body 2. On the housing 6, a movable carrier 7 is provided, which is movable along a guideway and corresponding opening, closing and / or damping forces on an activator 8 transmits, which is fixed to a running part 4. The running part 4 is fixed to the back of a front panel 60 of a sliding door, wherein per 60 front plate two spaced running parts 4 are provided. The number and position of the runners 4 can be selected depending on the weight of the front panel 60. FIG. 3 shows a modified embodiment of a fitting in which, in addition to the exemplary embodiment shown in FIG. 2, a further self-retraction 5 'is provided which has a housing 6' on which a catch 7 'is movably mounted. The driver 7 'can in turn be moved along a guideway and biased by a spring into an initial position. In addition, a damper on the self-closing 5 'can be positioned so that the front panel 60 can be braked or accelerated by the running part 4 via two self-feeds 5 and 5'. Especially with heavy front panels 60 thus a greater pull-in force or greater damping force can be generated. In Figure 4A, the fitting of Figure 2 is shown in a mounting position. The activator 8 comprises a protrusion 80 which protrudes substantially perpendicularly from the plane of the front plate 60, the activator being oriented downwards in the assembly position. The activator 8 is rotatably mounted about an axis 83, wherein in a mounting position between an upper surface 84 and a lower side of the rail 3, a gap L is present, which allows lifting of the running part 4 with the front panel 60. The gap L is greater than a vertical portion of a side wall 33, which limits the track 32. Thereby, by lifting the front plate 60, the roller 9 can be dug out of the raceway 32 and moved over the side wall 33 to disassemble the front plate 60.

FIG. 4B shows the fitting of FIG. 4A in a functional position. The activator 8 has been pivoted by about 90 °, so that the projection 80 is no longer positioned below the axis 83, but substantially at the same level with this. In this position, the projection 80 of the activator 8 can engage with a driver 7 of a self-closing, as shown in Figure 2. By turning the activator 8, a stop 85 is further arranged below the rail 3, which is arranged closer to the rail 3 than the surface 84. This results in a gap 88 between the bottom of the track 32 and the stopper 85, which is smaller than the Height of the side wall 33 on the rail 3 and thus smaller than the gap L is. This avoids lifting of the front plate 60, in which the roller 9 could be removed laterally over the side wall 33, so that the stop 85 serves as a lift-off.

In the figures 5A to 5C, the running part 4 of the fitting of Figure 2 is shown in detail. The running part 4 comprises a plate-shaped support 40 on which a holder 41 is mounted. Between the holder 41 and the plate-shaped carrier 40, a roller 9 is rotatably mounted, wherein on the carrier 40, if necessary, a plurality of rollers 9 can be provided. Below the roller 9 is the rotatably mounted activator 8, which is shown in Figure 5A in a mounting position. From this mounting position, the activator 8 can be selectively pivoted clockwise or counterclockwise to be brought into a functional position. In FIG. 5B, the activator 8 has been pivoted to the right, so that the projection 80 can now come into engagement with a driver on the right side of the carrier 40. The activator 8 is thereby up to a stop 86 on the carrier 40th pivoted, which is formed for example by an embossing. Alternatively, the activator 8 can also be pivoted in the clockwise direction by 90 °, as shown in Figure 5C. The activator is now directed to the left, and the protrusion 80 is disposed on a left side of the carrier 40. In this case, the activator 8 can be latched in the functional positions in FIGS. 5B and 5C, so that a stable arrangement is ensured. By pivoting the activator 8 is determined whether the running part 4 is a right or left running part, so that identical parts running 4 can be delivered and is decided only during assembly, whether it is a right or a left-hand component.

In FIGS. 6A to 6D, the fitting of FIG. 5 is shown in detail. The activator 8 comprises an undercut receptacle into which a mushroom-shaped bolt 82 or a rivet can be inserted. The bolt 82 comprises a widened head section, so that removal of the activator 8 from the plate-shaped carrier 40 can be prevented. This increases the stability of the activator 8 and reduces the load on the central axis 83. The axis 83 may also be formed as a mushroom-shaped bolt or rivet to rotatably support the activator 8 on the carrier 40. In this case, a mushroom-head-shaped bolt 82 is fastened to the support 40 on opposite sides, which can, depending on the rotational movement of the activator 80, come into engagement with the corresponding receptacle or not.

In FIG. 6D, the abutment 86 is shown in detail on the plate-shaped support 40, which is designed as an embossing and forms a stop for the activator 8. Further, it can be seen that the activator 8 has a channel to receive the mushroom-headed bolt 82. On the channel, a latching spring bar 87 may be provided to lock the activator 8 in a functional position and to avoid accidental release.

Shown in FIGS. 7A and 7B is a modified embodiment of a fitting substantially corresponding to the fitting shown in FIGS. 5 and 6. Instead of a mushroom-shaped bolt 82, a flared tab 92 is provided on the plate-shaped support 40, on which an opening 94 is formed. The activator 8 can be latched on the tab 92 instead of on the mushroom-shaped bolt 82, for which purpose a latching nub 93 engages in the opening 94. Incidentally, the fitting corresponds to the previous embodiment. FIGS. 8A to 8C show a further embodiment of a fitting in which a stop 86 is provided in the plate-shaped carrier 40, on which the activator 8 can be applied. The activator 8 is also in a functional position beyond the plate-shaped support 40, so that an edge 103 rests against an end edge of the plate-shaped support 40. As a result, the stability of the activator 8 can be additionally increased. Otherwise, the running part 4 corresponds to the previous embodiments.

FIGS. 9A to 9C show a further exemplary embodiment of a running part of a fitting according to the invention. The running part comprises a plate-shaped support 40 on which a roller 9 is rotatably mounted. Instead of a pivotable activator, a displaceable activator 10 is provided, which is movable along a curve guide. For this purpose, 40 two mushroom-shaped bolts 13 are fixed to the plate-shaped support 40, each engaging in a guide track 1 1. As a result, two guide tracks 11 are formed on the activator 10, which have an angled section 12. On the activator 10, a protruding perpendicularly from the plane of the front plate 60 projection 14 is formed, which can get into engagement with a receptacle on a driver 7.

In Figure 9D, the activator 10 is shown in a mounting position. In this position, the roller 9 can be hung on a rail 3 on a top floor 20. Once assembled, the activator 10 may be slid along the mushroom-shaped bolts 13 until the position shown in Figure 9A is reached. The activator 10 has been shifted so that below the roller 9 now a stop 15 of the activator 10 is provided, which prevents lifting of the running part. In this case, a spring 16 presses the activator 10 down to avoid accidental release of the activator 10 from the functional position. By the spring 16, the mushroom-shaped bolts 13 are held locked at an angled end portion 17. The locked end portion 17 is formed only on the left guide track 1 1, but it would also be possible to provide such a lock on the right track 1 1. If the running part to be lifted from the rail 3, the activator 10 must first be moved along the guide track 1 1 again, then lift the roller 9 accordingly and be able to lift out of the rail 3.

The plate-shaped carrier 40 of the running part 4 can be made in the embodiments of a stamped and bent metal sheet. In the embodiments shown, the activators 8 are mounted pivotably or displaceably. Of course, it is also possible to prefer other mechanisms for moving the activator in order to bring it from a mounting position into a functional position.

In addition, the application of the fitting is not limited to furniture, sliding doors or sliding elements can also be used in household appliances or other areas.
