It is an object of the invention to provide a retraction device of the type mentioned, with a sliding door can be aligned in a simple manner in a central position. It is a further object of the invention to develop a feeder arrangement or a method for fixing a sliding door for this purpose.

The object of the invention relating to the pull-in device is achieved in that the guide has a second parking section into which the release part is adjustable into a second parking position, and in that the second parking section is arranged offset in the direction of damping relative to the first parking section. With this retraction device it is possible to drive the sliding door in its movement out of the first end position against the triggering part and to move it out of the parking section. Then the spring and the damper take effect and the sliding door is pulled into its middle position. Now, however, the sliding door can be moved further into the second end position, since the release part can also be adjusted to a second parking position. In this second parking position then the driver is released again and the sliding door can move to the second end position.

According to the invention, it is provided that the release part has a driver receptacle, that the driver receiver is released in the first parking position assigned to the first parking portion and in the second parking position for receiving a driver. In this way, the sliding door can be adjusted out of its two end positions into the catch receptacle and thus caught by the release part.

It is particularly advantageous if it is provided that the cam receiver is released in the first parking position counter to the damping direction and that the cam receiver is released in the second parking position in the damping direction. In this way, a simple retraction of the driver in the driver receptacle is possible.

A particularly simple constructive embodiment results for the retraction device when it is provided that the trigger part is coupled to a carriage or has this, and that the carriage receives the trigger part adjustably.

A particularly reliable fixation of the driver in the driver receiving succeeds in particular when it is provided that the driver receiving two attacks are assigned to the determination of the driver in the driver. Then it prevents that from happening strong impact of the driver on the respective stop, the driver springs back from the driver receiving.

In order to guarantee a reliable use of the feeder device, in particular during the initial assembly or in case of incorrect operation, it is provided according to a further variant of the invention that one or both stops are adjustable transversely to the adjusting movement of the trigger member against the bias of a spring element. In this way, the stops are of the shape that they can be spring back if the driver is not in its intended operating position. The driver can then move past the spring-loaded stop into the driver seat.

For the purpose of a stable guidance of the release part, it may be provided that the carriage with a guide lug in a carriage guide between the two parking positions associated positions is passable.

A further preferred variant of the invention is characterized in that the release part has two guide pieces, which are guided adjustably in the guide, and that in each case a guide piece in the assigned parking position in a parking section is retractable. With the guide pieces a defined assignment of the trigger part in the parking position and thus a reliable determination of the trigger part is guaranteed.

According to a further variant of the invention, it is provided that the trigger part is mounted on the carriage such that it performs a combined pivot-linear movement in the transition from the guide portion in the first and / or second parking section. In this embodiment, the release part can be pivoted during the process in the park position and additionally be drawn into the housing of the feeder for the purpose of a low height.

The object of the invention relating to the intake arrangement is achieved by the features of claim 10. Accordingly, a feeder assembly, in particular for sliding doors, provided with two release parts, which are respectively connected to a damper and a spring, wherein the effective direction of the damper and the springs are in opposite directions. Each trigger part is provided to guide the sliding door from an end position to the middle position. In this way, a damped retraction of the sliding door is achieved in the adjustment from the first end position to the middle position. When adjusting from the second end position out a damped retraction movement of the sliding door in the middle position is also possible with the second trigger part.

The object of the invention relating to the method for fixing a sliding door is solved by the features of claim 12. Accordingly, it is provided that the sliding door is adjustable from a central position on both sides in an end position, wherein the sliding door is moved from the first end position by means of a driver against a first trigger part of a retraction device, that the first trigger part is adjusted from a parking position that the first trigger part is pulled by a spring and counter to the damping effect of a damper in the middle position, and that the trigger member is adjusted when adjusting the sliding door from the center position to the second end position into a second parking position and the driver is released.

This again allows a guided adjustment of the sliding door in the middle position from both end positions out.

It may be provided in particular that the driver is received in the middle position of the sliding door on a second trigger part of a second retraction device, and that when adjusting the sliding door from the middle position into the second end position, a connected to the second trigger part spring is tensioned. This spring can be used subsequently in adjustment from the second end position to the middle position to allow retraction of the sliding door.

A preferred variant of the invention may be of the form that when moving the sliding door from the second end position to the middle position, the spring of the second release part relaxes and the second release part is damped against the damping effect of a damper.

1 shows a feeder 10 with a housing 11 that a recording 12 having. In the recording 12 is a damper 20 accommodated. The damper 20 is designed as an air damper and has a cylinder 21 on, in which a piston is linearly adjustable. On the piston is a piston rod 22 connected with a tail 23 concludes. The damper 20 can in the recording 12 be determined. So the damper 20 in the direction of the longitudinal axis of the piston rod 22 held immovable, are holders 15 on the housing 11 provided in a groove of the cylinder 21 intervention. Furthermore, in the recording 12 of the housing 11 a feather 30 brought in. The feather 30 is with her left-side spring end 31 at one, in the 1 set bracket not shown. The second end 31 the feather 30 is on a sled 40 moored in the case 11 is linearly adjustable. The piston rod 22 grips with her tail 23 also on the sled 40 and is associated with this, as described below with reference to the 11 and 12 is explained in more detail.

As these drawings show, the sled is 40 integrally formed as a plastic injection molded part. He has a base part 41 on, that is a mounting fixture 42 having a bolt. The piston rod 22 is with her tail 23 set in this recording, with the tail 23 with a hole on the bolt of the mounting bracket 42 is deferred. This will be the piston rod 22 in the direction of its longitudinal extension immovable with the carriage 40 connected.

At the base part 41 is still a pen 46 intended. At this penholder 46 can the spring end 31 the feather 30 be determined. The sled 40 is still with a storage section 43 fitted to the base part 41 followed. The storage section 43 makes a recording 44 for a trigger part 50 , The trigger part 50 is formed like a box and has two stops 53 and 54 on. These attacks 53 and 54 are in the in the 11 and 12 shown vertical direction slidably in the trigger part 50 held. The attacks can 53 . 54 vertically downwards (according to the 11 and 12 ) against the bias of a spring element in the trigger part 50 be inserted. The trigger part 50 also has two guide pieces 51 . 52 on, as a bolt-shaped approaches to the trigger part 50 are integrally formed. On the leader pieces 51 . 52 turned away side is to the trigger part 50 a storage item 55 formed. This bearing piece 55 stands over a flat surface of the trigger part 50 before, wherein the flat surface on the facing flat surface of the bearing section 43 to form a sliding surface. The bearing piece 55 engages in a camp recording 45 of the sled 40 one. The camp recording 45 is designed as a slot. The trigger part 50 can therefore against the slide 40 be pivoted, wherein the central longitudinal axis of the journal-shaped bearing piece 55 forms the pivot axis. Furthermore, the trigger part 50 in the slot-like bearing receiver 45 be vertically limited. The pivoting and adjusting movement of the release part 50 is about the area between the bearing section 43 and the facing surface of the trigger part 50 guided.

As the 1 shows is the sled 40 and trigger part 50 formed unit in the housing 11 the feeder 10 used. The guide pieces grip 51 and 52 in a guide 13 that as a breakthrough in the case 11 is incorporated. The leadership approach 47 of the sled 40 engages in a carriage guide 16 one, the leadership 13 opposite and also as an opening or groove in the housing 11 is incorporated. That way, the sledges 40 / Release part 50 Unit in the lead 13 and the sledge guide 16 guided. The walls of the housing 11 in which the lead 13 and the sledge guide 16 are formed, prevent falling apart of the release part 50 and the sled 40 so that can be dispensed with separate fasteners. The carriage guide 16 especially the 5 be removed.

The leadership 13 has a guide section 13.1 on, which is designed as a linear section. At the guide section 13.1 Park sections are closed on both sides 13.2 and 13.3 at. The park sections 13.2 and 13.3 are doing as angled or arcuate areas of the guide section 13.1 connected.

1 lets further recognize that to the housing 11 on both sides at the longitudinal ends flanges 14 are formed. The flanges 14 have fastening fixtures 14.1 on (see 5 ). With these mounting shots 14.1 can the feeder 10 be bolted to the housing body of a piece of furniture. The feeder 10 is used to align sliding doors on this furniture. For this purpose, there is an activator on the sliding door 60 with a molded-on driver 61 formed. The activator 60 Can via attachment shots 62 screwed on the inside with the sliding door. The feeder 10 For example, it can be bolted to the inside of a cupboard compartment on the open side of the cupboard compartment facing the sliding door on the ceiling side (screw receptacles) 14.1 ). The driver 61 is dimensioned to be between one of the two stops 53 and 54 limited entrainment 56 Can find space (see 2 ).

Below is the function of the feeder 10 with reference to the 1 to 6 explained in more detail.

In the 1 is the damper 20 shown in its extended position, the piston rod 22 out of the cylinder 21 partially pulled out and the piston is in its final position. The feather 30 is in its tense position, giving it a pulling force on the slide 40 exercises. The trigger part 50 is in its first tilted park position, being the leader 51 in the first park section 13.2 is included. The second guide piece 52 is located in the area of the guide section 13.1 , Thus prevents the leader 51 , due to the positive fitment in the first parking section 13.2 a shift of the carriage 40 in the direction of the longitudinal extension of the guide section 13.1 , The sliding door comes together with the activator 60 shifted from its right-hand end position to the left, as the arrow S in 1 illustrated. During this sliding movement of the driver hits 61 on the stop 53 , 1 shows the operating position shortly before impact of the driver 61 on the stop 53 , If now the driver 61 on the stop 53 a force hits the stop 53 applied. This force acts eccentrically to that through the bearing piece 55 formed pivot axis of the trigger part 50 , In this way, a counterclockwise rotating torque on the trigger part 50 applied. This torque causes the guide piece 51 from the area of the first parking section 13.2 is dug. Then the guide piece arrives 51 in the region of the linear guide section 13.1 , Since now the positive connection between the first parking section 13.2 and the trigger part 50 is canceled, the spring can 30 be effective. This now pulls the sledge 40 and with it the trigger part 50 in the picture plane according to 1 to the left. The spring force is the damping effect of the damper 20 opposed. That way, the sled becomes 40 dampened adjusted. The guide of the sled 40 is doing by the two leaders 51 and 52 as well as the leadership approach 47 and the associated leadership 13.1 or the slide guide 16 accepted.

2 now shows the functional position of the trigger part 50 and with it the sled 40 just before the leader piece 52 the second parking section 13.3 reached. Now, if the sliding door is pulled further to the left (by the spring 30 ) so becomes the leader 52 at the arcuate end portion of the second parking portion 13.3 deflected and in this park section 13.3 tilted into it. In 4 is the tilted position of the trigger part 50 shown. As this illustration shows, is the stop 53 now dumped, and the driver intake 56 is released. This can be the driver 61 and with him the sliding door can be further adjusted in freewheel to the left.

Like the character sequence according to the 1 to 4 Thus, a sliding door can thus be moved out of its left end position until it touches the release part 50 meets. The trigger part 50 then catch the sliding door and pull it into the 4 shown middle position into it. From the in 4 shown defined end position then the sliding door in the freewheel can be moved further into the other end position (left-side end position). Now, if the sliding door is to be adjusted from its left end position to the right, the figure sequence must be in accordance with the 4 to 1 to go through. It hits the driver 61 first on the attack 54 ( 4 ) and lifts it due to the eccentric force from its second parking position 13.3 , This is the leader 52 from the second park section 13.3 lifted out until it is in the area of the linear guide section 13.1 passes (transition from 4 to 3 ). Subsequently, the trigger part 50 be moved to the right until it reaches the area of its first parking position. This is the leader 51 in the area of the first parking section 13.2 brought. This is achieved by the eccentric to the pivot axis of the release part 50 acting spring force of the spring 30 , This tilts the leader 51 down, like this 2 and 1 demonstrate. In the in 1 shown position is now again the driver intake 56 released and the sliding door can be moved in the freewheel to the right.

5 shows the functional position of the feeder 10 according to the 4 , where the driver 61 from the driver intake 56 moved out. As this drawing illustrates, the sliding door can now be moved to the right (arrow S) until it stops 54 meets. Then the operating position is according to 4 reached. The drawing according to 4 corresponds with the drawing according to 6 ,

In the 7 to 10 is now an expanded embodiment of a feeder assembly using two retracting devices 10 according to the 1 to 6 shown. Like these drawings 7 to 10 show, are the two collection devices 10 strung together so that the directions of action of the springs 30 and the damper 20 are in opposite directions. Accordingly, the damping direction of the damper 20 the front intake device 10 to the left, while the damping action of the damper 20 the second, rear intake device 10 works to the right. With the in the 7 to 10 shown feeder assembly 10 a sliding door defined from both end positions can be pulled into the middle position. It can therefore always be aligned exactly in the middle position. If the sliding door now, for example, like this 7 shows, is moved from its right end position to the left, so it hits the trigger part 50 the front intake device 10 , Then the above-described sequence of the feeder becomes active. The trigger part 50 moves to the left until the leader piece 52 this first trigger part 50 in the associated second parking section 13.3 is recorded. As the 7 shows is now the rear feeder 10 in the operating position, as described above with reference to the 5 . 6 respectively. 4 has been explained. During the movement of the sliding door to the left, therefore, the driver 61 the stop 53 the tilted second trigger part 50 the rear feeder 10 run over until he is in 8th achieved middle position shown. The driver 61 is now at the second stop 54 of the second trigger part 50 the rear feeder 10 captured. At the same time is the driver 61 but also to the stop 54 the front intake device 10 established. Thus, the sliding door can not be easily moved to the left or right, it is trapped in its center position.

Now if the sliding door is to be moved to the left, as the arrow S in the 8th shows, then this must be the trigger part 50 the rear feeder 10 be moved to the left. The displacement movement takes place against the force of the spring 30 the rear feeder 10 , where the spring 30 is tense. At the same time the damper 20 the rear feeder 10 moved out. The driver 61 takes the trigger 50 so long with, until the rear intake device 10 placed in the second parking position. This parking position corresponds to the representation according to 1 , Then the sliding door can be moved further to the left until it finds its left end stop position.

If the sliding door is now to be moved from its left end stop position to the central position, it first encounters the stop 53 the rear feeder 10 and is caught at this. Under force can now the trigger part 50 the rear feeder 10 be deflected from the second parking position. Then the spring 30 and the damper 20 the rear feeder 10 effective and pulls the sliding door into the 8th middle position shown. The sliding door is on her driver 61 again between the two attacks 54 (rear feeder 10 ) and 54 (front feeder 10 ) captured. If the sliding door is moved further to the right, the spring becomes 30 the front intake device 10 loaded and tense. The damper 20 is pulled out until the operating position according to 7 is reached. Then the sliding door can be moved in the freewheel further to the left.

The pair of figures 8th and 9 shows the switching process, where the driver 61 from the driver intake 56 the front intake device 10 to the driver intake 56 the rear feeder 10 is handed over.
