Description

retraction device

The invention relates to a feeder device, in particular for sliding doors, drawers or the like.

Such a retraction device is known from DE 10 2008 009 046 A1. In this case, the sliding door between an open and a closed position can be moved back and forth. In order to prevent now that the sliding door strikes hard in the open position when opening, a feeder is used. This retractor catches the sliding door opening and slows down its momentum. At the same time a retraction spring is effective, which pulls the sliding door against the damping force of the damping device in the open position.

In modern furniture sliding doors are often used, which serve to selectively cover three juxtaposed cabinet compartments. DEM Accordingly, the sliding door can be adjusted so that it covers either the left, the right or the middle cabinet compartment.

The sliding door can be pulled with a retraction device shown in DE 10 2007 008 363 B3 in each of the left or right cabinet associated end position. In the center position alignment of the sliding door is not possible with this known feeder.

There are also known applications in which a drawer is extendable from a furniture body in two opposite directions.

It is an object of the invention to provide a retraction device of the type mentioned, with a sliding door, drawer or the like (hereinafter collectively called "sliding door") can be aligned in a simple manner in an intermediate position.

It is a further object of the invention to provide a method for aligning a sliding door or the like in an intermediate position.

The object of the invention is achieved with a retraction device which has a trigger part which forms a driver receptacle, wherein the trigger part between a first and a second parking position is adjustable. In the first parking position, the release part releases the catch receptacle in a first direction and in the second parking position in a second direction. A sliding door can thus be equipped, for example, with a driver, which enters the driver receiving. If the trigger member is in the first parking position, the driver can come from one direction coming into the driver receiving and then held in this driver. By means of the feeder device, the driver and thus the sliding door in an intermediate position is then positioned. ned. In order to hold this intermediate position and thus align the sliding door, the trigger part is coupled between the end positions with two oppositely acting back part devices. It can be provided in particular that the triggering part coupled in an intermediate position between the parking positions with two oppositely acting pulling devices. The sliding door can be adjusted from the intermediate position in both directions and moved out of the effective range of the release part.

According to a preferred embodiment of the invention it can be provided that at least one of the rear part devices has a spring and a damper and that the tensile force of the spring counteracts the damping force of the damper. In this way, the sliding door is pulled with the spring in the intermediate position and the damper simultaneously dampens the retraction movement, so that a slowing down of the sliding door is achieved and this is gently braked. As a result, the ease of use for the sliding door is significantly increased.

A retraction device according to the invention can in particular also be such that the rear part device has a tilting segment with a coupling piece receptacle, and that the tilting segment is adjustable between a freewheeling position and a coupling position. In this way, a reliable effective releasable connection between the return device and the release part can be made. It can also be provided in particular that the tilting segment is pivotally connected to a connector which is indirectly and / or directly coupled to the spring or the damper. As a result, a simple construction is achieved.

The trigger part may have a catch element or be coupled to such. In this case, the catch element then has two coupling pieces which can be detachably coupled to one of the rear part devices in each case. In order to ensure sufficient way to have to transfer the sliding door into the intermediate position, a variant of the invention provides that the coupling pieces are each arranged at a connecting portion in the guide direction of the release part spaced from the triggering part.

A reliable operation of the intake device can for example be achieved in that the trigger member is adjustable on a guide in a guide direction, and that the trigger member is adjustable by means of a pivot bearing in the first and the second parking position. Here, a conceivable simple structure for the feeder is achieved.

Particularly preferably, the triggering part can have a first and a second blocking element which delimit a receptacle. In the recording, a driver, which is mounted, for example, sliding door side, are recorded. The locking elements alternately in the two parking positions each recording free, so that the driver can be easily retracted and extended. When using the two locking elements, it may also be provided that these locking elements are each deflectable by means of a spring portion. This prevents a malfunction. If the driver is not in the correct assignment to the trigger part, for example, by a mounting error, then the driver can run over the respective deflectable locking element and thus get back into the receptacle formed between the locking elements.

According to a preferred variant of the invention, provision may be made for the release part to be adjustably mounted in one guide by means of one or more guide elements, and for the guide elements and / or one or more blocking pieces to lock the release part in the first and / or second parking position. A reduction of the parts expense results from the fact that a driver is coupled in the intermediate position with the trigger part and in the end position of the sliding door with a tail end damper.

The object of the invention is also achieved with a method for locking a parking position of a sliding door, wherein the sliding door is adjustable from an intermediate position on both sides in an end position, and wherein the sliding door or the like between two end positions by means of two rear part devices can be coupled. About the rear part devices, the sliding door is defined in a position held and thus aligned accurately and reproducibly.

In this case, in particular, a collection device can be designed, which is characterized by a low parts and assembly costs.

In this case, it is particularly conceivable that the sliding door or the like is coupled in the intermediate position simultaneously with the two rear part devices.

According to the invention, it can also be provided, in particular, that the sliding door is moved out of the intermediate position in the direction of the end position, that the sliding door is engaged by a limit stop when adjusting the sliding door, and that the end stop damper pulls the sliding door into the end position under the action of a spring and at the same time it dampens. Thus, the sliding door can not only be aligned and locked in the intermediate position, but also in its end position. As a result, compared to the prior art significantly improved ease of use is achieved.

Particularly preferably, it can be provided that the sliding door or the like is held in the intermediate position on two tilt-ready tilting segments. According to a further variant of the method of the invention, it may be provided that the rear part devices have counter-acting springs and / or dampers. The opposing springs pull the sliding door in the middle position in the interplay, whereby the force of one spring breaks down and the other balancing builds. The counteracting dampers prevent the sliding door from hitting hard during the pulling process.

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

Figure 1 is a furniture with a sliding door in perspective view;

Figure 2 shows the illustration of Figure 1 in a changed operating position;

Figure 3 shows the furniture according to Figures 1 and 2 in a further modified operating position;

Figure 4 to 6, the furniture according to Figures 1 to 3 each in plan view;

Figures 7 to 12 in detail view of a feeder, partly in section in different operating positions

Figures 13 to 15 a further functional representation of the feeder in a further enlarged detail and in plan view and partly in section with different operating positions.

Figure 1 shows a piece of furniture with a furniture body 10, which has a top wall 1 1 and a bottom wall 12 and two lateral vertical side walls 13, 14. On the front side of the furniture body 10 is a sliding door 15 with a conventional sliding guide struck. The sliding door 15 can be offset in the horizontal direction, as symbolized by the double arrow. The sliding door 15 can be moved starting from the middle position shown in FIG. 1 into the right end position shown in FIG. 2 or into the left end position shown in FIG. In the middle position according to FIG. 1, the sliding door 15 is held by means of a sliding door damper 20. In the left and right Endlagenposition the sliding door 15 is held by means of a respective Endlagendämpfers 16. The function of the end stop damper 16 is described in more detail in DE 10 2008 051 360 A1. Accordingly, the end-position damper 16 has a pull-in spring and a damper acting against the spring tension, which act together on a tilting segment 16.1.

In Figure 4, the left-side Endlagendämpfer 16 is shown with its tilting segment 16.1 in a freewheeling position. The right end stop damper 16, however, is shown in a catching position. Accordingly, a driver 30.2 of an activator 30 is caught by the tilting segment 16.1. The tilting segment 16.1 is released from its freewheeling position and pulled by the spring in the end position. At the same time dampens the damper of Endlagendämpfers this retraction movement. If the sliding door 15 is moved to the left from the right end position shown in Figure 4, then the driver 30.2 pulls the tilting segment 16.1 to the left. The spring of Endlagendämpfers 16 is stretched and pulled out the damper. As soon as the tilting segment 16.1 is moved into the freewheeling position, the activator 30 is released. The freewheeling position is shown in FIG. In a further shift to the left, the activator 30 comes into operative connection with the sliding door damper 20, as shown in FIG.

Another offset to the left releases the activator 30 from the sliding door damper 20. The activator 30 can then be brought into operative connection with the left end stop damper 16. The end stop damper 16 is identical to the right end stop damper, so reference may be made to the above operation. Hereinafter, the operation of the sliding door damper 20 will be explained with reference to FIGS.

Figure 7 shows the sliding door damper in the view shown in Figure 5, wherein the housing of the sliding damper is partially cut to better recognize the operation can. As can be seen from this illustration, the sliding door 15 is arranged at the front and the activator 30 is fastened to the sliding door 15 on the cover side by means of the fastening section 30.1. The activator 30 carries the driver 30.2, the rear side over the sliding door 15 protrudes a piece far. The driver 30.2 engages in the receptacle A of a catch element 40 a. The catch element 40 has a holder 41, which has a plate with bolt guides 41 .1, 41 .2. The bolt guides 41 .1, 41 .2 are excluded as arcuate slots from the holder 41. Left and right side of the vertical plane of symmetry of the catch element 40 is a bolt guide 41 .1, 41 .2 provided. The holder 41 has a front-side vertical wall section, which carries integrally formed on the left and right in the sliding direction connecting portions 41 .4. The connecting sections 41 .4 terminate in coupling pieces 41 .5. These are integrally formed on the connecting portion 41 .4 and protrude back over the connecting portion 41 .4. The catch element 40 has a rear wall 41 .3, which abuts on the inside on a rear wall 25 of the housing 20 slidably.

The housing 20 has two mutually parallel wall elements 20.1, which are connected to each other by means of the rear wall 25. In the mutually facing sides of the wall elements 20.1 guides 21 are incorporated in the form of recessed grooves. The guides 21 have a linear section, which opens into lateral receptacles 22 and merges into locking sections 23. Furthermore, the guides 21 each have a receptacle 24. In the guides 21 is a trigger part 50 of the Catch element 40 out. This trigger part 50 is shown in more detail in FIGS. 13 to 15.

As these illustrations illustrate, the catching element 40 forms a box-like holder 41. The recognizable in Figures 7 to 9 top wall of the holder 41 is cut to better recognize the trigger member 50 can. The triggering part 50 has two blocking elements 51, 52. In this case, each blocking element 51, 52 by means of a spring portion 51 .1, 52.1 articulated coupled to a connecting element 53, for example, integrally formed. The spring portion 51 .1 is molded like a leaf spring on the connecting element 53. Turning away from the connecting element 53, the spring section 51 .1, 52.1 merges into a transition piece 51 .2, 52.2, which then merges into an engaging part 51 .3 and 52.3. The Anlegeteil 51 .3, 52.3 carries at its free end a blocking piece 51 .4, 52.4. To the connecting element 53 two locking pieces 55 are integrally formed. Furthermore, in the transition region of the connecting element 53 to the spring portion 51 .1, 52.1 guide elements 54 are formed. In this case, the guide elements 54 and the locking pieces 55 are designed as bolt elements which protrude on both sides of the image plane according to FIG. 13 on the front and rear sides via the connecting element 53. The guide elements 54 are guided in the bolt guides 41 .1 and the locking pieces 55 in the bolt guides 41 .2. Accordingly, the trigger member 50 is guided on both sides in the catch element 40. The connecting elements 53 and the guide elements 54 are formed so that they pass through the bolt guides 41 .1, 41 .2 and extend beyond the catching element 40 in such a way that they engage in the guides 21.

In the middle position shown in FIG. 7, the coupling pieces 41 .5 of the connecting sections 41. 4 are held in tilting segments 64 of rear-part devices 60. The two rear part devices 60 are constructed identically. They each have a spring 61 and a damper 62. One end of the spring 61 is in the housing se 20 fixed. The other end of the spring 61 is fixed to a connector 63. For this purpose, the connector 63 has an integrally formed spring holder 63.2. Furthermore, the connector 63 has a piston rod receptacle 63.1, to which the piston rod 62.1 of the formed as a fluid linear damper damper 62 is fastened. The connector

63 carries the tilting pad 64 by means of a pivot bearing. This is formed by a guide 63.4 incorporated as a recess in the connector 63 and a bolt 64.2 guided therein. Furthermore, the tilting segment 64 is held in the guides 21 of the housing 20 by means of guide elements 64. 1 protruding on both sides. As mentioned above, the back-up devices 60 are constructed substantially identically, so that the sliding-door damper 20 is constructed symmetrically to its vertical central transverse plane passing through FIG.

Hereinafter, the operation of the sliding damper 20 will be explained in more detail.

If the sliding door 15 is moved to the right starting from the middle position shown in FIG. 7 (see arrow S), then the catching element 40, which receives the catch 30.2, is also adjusted to the right. As a result, the tilting segment 64 of the right-hand rear-part device 16 is pivoted into its freewheeling position, which is shown in FIG. This pivoting succeeds simply because the coupling piece 41 .5 acts eccentrically to the pivot axis formed by the guide element 64. 1 and the guide 21. Thus, the coupling piece 41 .5 pushes the tilting segment

64 in the tilted freewheeling position shown in Figure 8, and the coupling piece 41 .5 is released from the coupling piece receptacle 64.3. Then the coupling piece 41 .5 can be moved in the freewheel to the right, and the coupling of the right-side rear sub-device 60 is released. The spring 61 of this retraction device 60 holds the connector 63 to stop in the position shown in Figure 8.

The left-side rear part device 60, however, is stretched with the left coupling piece 41 .5. In this case, the left-side coupling piece 41 .5 pulls the tilting segment 64 in the guide 21 to the right. As a result, the connector 63 is also displaced to the right, and the piston rod 62.2 of the damper 62 is pulled out. At the same time, the spring 61 is tensioned. This tensioning movement takes place until the catching element 40 reaches the position shown in FIG. Then the trigger member 50 tilts into the freewheeling position, in which the receptacle A releases the driver 30.2. To achieve this free-running position, the left-side bolt 54 of the release part 50 pivots into the receptacle 22 of the guide 21. The right-side guide member 54 is placed in the receptacle 24. The left-side locking piece 55 forms the pivot axis of the release part 50, so that the right-side locking piece 55 is pivoted into the locking portion 23 and here against the sliding direction of the sliding door 15 is positively fixed. Now, if the trigger member 50 releases the driver 30.2, the sliding door 15 can be moved to the right side unloading position. The left-side rear part device 60 remains in its clamping position shown in Figure 9. Now, if the sliding door is moved from its right end position back to the middle position, then the driver 30.2 passes in accordance with Figure 9 in the receptacle A. He then encounters the left-side locking element 51 of the trigger member 50. The driver acts 30.2 eccentric to that of the Locking piece 55 formed pivot axis and thus tilts under the action of a torque, the trigger member 50 from the position shown in Figure 9 in the sliding position shown in Figure 8. Then, the spring 61 is effective and pulls the catching element 40 together with the driver 30.2 in the middle position shown in Figure 7. The connector 63 of the left-hand back-up devices 60 abuts defined on the housing of the damper 62, so that the center position of the sliding door 15 is precisely determined. The right-side coupling piece 41 .5 moves into the tilting segment 64 and pivots it from the position shown in FIG. 9 into the blocking position according to FIG. 7. The triggering part 50 is thus held in a form-fitting manner on the two tilting segments 64.

In FIGS. 10 to 12, the procedure for displacing the sliding door 15 to the left in the direction of the left end position is shown. In doing so, identical see functional mechanisms effective, as in the adjustment from the middle position to the right end position. It can thus be made to the above statements.

It may happen that, for example, as a result of incorrect assembly, the driver 30.2 is not on the sliding door position corresponding side of the receptacle A of the trigger member 50, as shown in FIG. Then the driver 30.2 can not easily retract into the receptacle A. As the sequence of FIGS. 13 to 15 shows, in this case the driver 30.2 is moved against the spring section 51 .1. In this case, the spring portion 51 .1 forms a ramp. The driver 30.2 deflects the first blocking element 51, wherein the spring section 51 .1 yields. The system part 51 .3 swings freely. The driver 30.2 passes over the transition piece 51 .2. When it has passed this, the first locking element 51 snaps back into its starting position shown in Figure 15, wherein the blocking piece 51 .4 abuts against the connecting element 53 to fix the adjusting position of the first locking element 51. The driver 30.2 then enters the area of the receptacle A and is back in the correct operating position.

Since the trigger member 50 is formed symmetrically, the above working mechanism also works when the driver 30.2 the second right side blocking element 52 has to drive over.
