Description

The invention relates to a feeder device, in particular for sliding doors with a trigger member which is directly or indirectly coupled to a damper and a spring, wherein the trigger member from a first parking portion of a guide is movable out into a guide portion, and wherein the trigger member in the guide section opposite the damping force of the damper in the damping direction is adjustable.

Such retraction devices are from the DE 102007008 363 B3 known. Here, an activator with a driver is attached to the sliding door. When moving the sliding door of the driver enters the region of the trigger part and lifts it out of its parking position, whereby the trigger part is released. Then, a pull-in spring is effective, which pulls the trigger part from the parking position into a retracted position. At the same time, a damper acts on the trigger part, which dampens the pull-in force of the pull-in spring.

In modern furniture sliding doors are often used, which serves to selectively cover three juxtaposed cabinet compartments. 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 with the in the DE 10 2007 008 363 B3 shown pulling device are pulled into each of the left or right cabinet associated end position. In the middle position alignment of the sliding door is not possible with the known feeder.

A similar feeder is also from the DE 20 2004 006 412 or the EP 1 658785 B1 known.

Other collection devices for sliding doors are in the DE 20 2009 016 834 U1 described.

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 intake device is achieved by the features of claim 1. Accordingly, it is provided that the guide has a second parking section, in which the trigger part is adjustable into a second parking position into, and that the second parking section is arranged offset relative to the first parking section in the damping direction. 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 further provided that the trigger part has a driver receptacle, that the driver receptacle 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 in the second parking position in Damping direction is released. In this way, a simple retraction of the driver in the driver receptacle is possible.

A particularly simple structural design results for the retraction device according to the invention in that the trigger member 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 stops are assigned to the determination of the driver in the driver. Then it is prevented that in a strong impact of the driver on the respective stop, the driver springs back from the driver seat.

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. The guide pieces become a defined assignment the trigger part in the parking position and thus a reliable determination of the trigger part guaranteed.

According to the invention, it is further provided that the trigger member 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 portion. 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.

According to a further variant of the invention, an intake assembly with two release parts is proposed, which are each 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 9. 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. In this way, the pull-in force of the spring is reduced continuously and damped.

FIG. 1 shows a retraction device 10 with a housing 11 which has a receptacle 12. In the receptacle 12, a damper 20 is housed. The damper 20 is designed as an air damper and has a cylinder 21 in which a piston is linearly adjustable. To the piston, a piston rod 22 is connected, which terminates with an end piece 23. The damper 20 can be fixed in the receptacle 12. Thus, the damper 20 is held immovably in the direction of the longitudinal axis of the piston rod 22, brackets 15 are provided on the housing 11, which engage in a groove of the cylinder 21. Furthermore, a spring 30 is inserted into the receptacle 12 of the housing 11. The spring 30 is connected to its left-side spring end 31 at one in the FIG. 1 set bracket not shown. The second end 31 of the spring 30 is fixed to a carriage 40 which is linearly adjustable in the housing 11. The piston rod 22 engages with its end piece 23 also on the carriage 40 and is connected thereto, as described below with reference to the FIGS. 11 and 12 is explained in more detail.

As these drawings show, the carriage 40 is integrally formed as a plastic injection molded part. It has a base part 41, which has a fastening receptacle 42 with a bolt. The piston rod 22 is fixed with its end piece 23 in this receptacle, wherein the end piece 23 is pushed with a bore on the bolt of the fastening receptacle 42. Thus, the piston rod 22 is linked in the direction of its longitudinal extension immovably with the carriage 40.

On the base part 41, a spring holder 46 is further provided. At this spring holder 46, the spring end 31 of the spring 30 can be set. The carriage 40 is further equipped with a bearing portion 43, which connects to the base part 41. The bearing portion 43 forms a receptacle 44 for a trigger member 50. The trigger member 50 is formed like a box and has two stops 53 and 54 on. These stops 53 and 54 are in the in the FIGS. 11 and 12 shown vertical direction slidably held in the trigger member 50. In this case, the stops 53, 54 in the vertical direction downwards (according to the FIGS. 11 and 12 ) are pushed against the bias of a spring element in the trigger member 50. The trigger member 50 further comprises two guide pieces 51, 52, which are integrally formed as bolt-shaped projections on the trigger member 50. On the guide pieces 51, 52 side facing away from the support member 50, a bearing piece 55 is formed. This bearing piece 55 protrudes beyond a flat surface of the release part 50, the flat surface abutting against the facing flat surface of the bearing portion 43 to form a sliding surface. The bearing piece 55 engages in a bearing seat 45 of the carriage 40. The bearing holder 45 is designed as a slot. The trigger member 50 can therefore be pivoted relative to the carriage 40, wherein the central longitudinal axis of the journal-shaped bearing piece 55 forms the pivot axis. Furthermore, the trigger member 50 can be adjusted vertically limited in the slot-like bearing receptacle 45. The pivoting and adjusting movement of the triggering part 50 is guided over the flat contact between the bearing section 43 and the facing surface of the triggering part 50.

As the FIG. 1 shows, the unit formed by carriage 40 and trigger member 50 is inserted into the housing 11 of the feeder 10. The guide pieces 51 and 52 engage in a guide 13, which is incorporated as an opening in the housing 11, a. The guide lug 47 of the carriage 40 engages in a carriage guide 16, which is the guide 13 opposite and is also incorporated as an opening or groove in the housing 11. In this way, the carriage 40 / trip unit 50 unit in the guide 13 and the slide guide 16 is guided. The walls of the housing 11, in which the guide 13 and the slide guide 16 are formed, prevent falling apart of the trigger member 50 and the carriage 40, so that can be dispensed with separate fastening means. The carriage guide 16 can in particular the FIG. 5 be removed.

The guide 13 has a guide section 13.1, which is designed as a linear section. Park sections 13.2 and 13.3 adjoin the guide section 13.1 on both sides. The parking sections 13.2 and 13.3 are connected as angled or arcuate areas of the guide portion 13.1.

FIG. 1 shows further that flanges 14 are integrally formed on the housing 11 on both sides of the longitudinal ends. The flanges 14 have fastening receptacles 14.1 (see FIG. 5 ). With these fastening receptacles 14.1, the retraction device 10 can be screwed to the housing body of a piece of furniture. The feeder 10 is used to align sliding doors on this furniture. For this purpose, an activator 60 is integrally formed with a driver 61 formed thereon on the sliding door. The activator 60 can be screwed on the inside of the sliding door via fastening receivers 62. The feeder device 10 may be screwed, for example, on the ceiling side in the interior of a cabinet compartment on the sliding door facing open side of the cabinet compartment (screw 14.1). The driver 61 is dimensioned so that it can find space between a limited by the two stops 53 and 54 cam receiver 56 (see FIG. 2 ).

Hereinafter, the function of the retraction device 10 with reference to the FIGS. 1 to 6 explained in more detail.

In the FIG. 1 the damper 20 is shown in its extended position, the piston rod 22 is partially pulled out of the cylinder 21 and the piston is in its end position. The spring 30 is in its tensioned position, whereby it exerts a pulling force on the carriage 40. The trigger member 50 is in its first tilted parking position, the guide piece 51 is received in the first parking section 13.2. The second guide piece 52 is located in the region of the guide section 13.1. Thus prevents the guide piece 51, due to the positive engagement in the first parking section 13.2 a displacement of the carriage 40 in the direction of the longitudinal extent of the guide portion 13.1. The sliding door is moved together with the activator 60 from its right-hand end position to the left, as the arrow S in FIG. 1 illustrated. During this sliding movement of the driver 61 hits the stop 53rd FIG. 1 shows the operating position shortly before hitting the driver 61 on the stop 53. If now the driver 61 strikes the stop 53, a force is applied to the stop 53. This force acts eccentrically to the pivot axis of the release part 50 formed by the bearing piece 55. In this way, a rotating torque in the counterclockwise direction is applied to the trigger part 50. This torque causes the guide piece 51 is excavated from the area of the first parking section 13.2. Then the guide piece 51 comes 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 member 50 is released, the spring 30 can be effective. This now pulls the carriage 40 and with him the trigger part 50 in the image plane according to FIG. 1 to the left. The spring force is opposed to the damping effect of the damper 20. In this way, the carriage 40 is adjusted attenuated. The guide of the carriage 40 is thereby taken over by the two guide pieces 51 and 52 as well as by the guide projection 47 and the associated guide 13.1 or the slide guide 16.

FIG. 2 now shows the functional position of the trigger part 50 and thus of the carriage 40 just before the guide piece 52 reaches the second parking section 13.3. If now the sliding door is pulled further to the left (by the spring 30), the guide piece 52 is deflected at the arcuate end portion of the second parking section 13.3 and tilted into this parking section 13.3. In FIG. 4 the tilted position of the trigger part 50 is shown. As this illustration shows, the stop 53 is now tilted, and the cam receiver 56 is released. Thus, 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 FIGS. 1 to 4 Thus, a sliding door can thus be moved out of its left end position until it encounters the triggering part 50. The trigger part 50 then catches the sliding door and pulls it into the in FIG. 4 shown middle position into it. From the in FIG. 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 FIGS. 4 to 1 to go through. The driver 61 first encounters the stop 54 (FIG. FIG. 4 ) and lifts it from its second parking position due to the eccentric force 13.3. In this case, the guide piece 52 is lifted out of the second parking section 13.3 until it reaches the region of the linear guide section 13.1 (transition from FIG FIG. 4 to FIG. 3 ). Subsequently, the trigger member 50 can be moved to the right until it reaches the area of its first parking position. In this case, the guide piece 51 is brought into the region of the first parking section 13.2. This is achieved by the force acting eccentrically to the pivot axis of the trigger member 50 spring force of the spring 30. This tilts the guide piece 51 down from how the Figures 2 and 1 demonstrate. In the in FIG. 1 shown position is now again the cam receiver 56 released and the sliding door can be moved in the freewheel to the right.

FIG. 5 shows the functional position of the retraction device 10 according to the FIG. 4 , wherein the driver 61 is moved out of the Mitnehmeraufnahme 56 out. As this drawing illustrates, the sliding door can now be turned to the right (arrow S) be moved until he meets the stop 54. Then the operating position is according to FIG. 4 reached. The drawing according to FIG. 4 corresponds with the drawing according to FIG. 6 ,

In the FIGS. 7 to 10 is now an expanded embodiment of a feeder assembly using two intake devices 10 according to the FIGS. 1 to 6 shown. As these drawings show 7 to 10, the two retraction devices 10 are lined up 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 of the front intake device 10 is to the left, while the damping action of the damper 20 of the second, rear intake device 10 acts to the right. With the in the FIGS. 7 to 10 shown feeder assembly 10, a sliding door defined from two 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 FIG. 7 shows, is moved out of its right end position to the left, it strikes the trigger part 50 of the front feed device 10. Then the above-described sequence of the feeder is active. The triggering part 50 moves to the left until the guide piece 52 of this first triggering part 50 is received in the associated second parking section 13.3. As the FIG. 7 is now the rear intake device 10 in the operating position, as described above with reference to the Figures 5 . 6 and 4, respectively. During the movement of the sliding door to the left, therefore, the driver 61 can run over the stop 53 of the tilted second release part 50 of the rear intake device 10 until it reaches the in FIG. 8 achieved middle position shown. The driver 61 is now caught on the second stop 54 of the second release part 50 of the rear intake device 10. At the same time, the driver 61 is also fixed to the stop 54 of the front intake device 10. 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 FIG. 8 shows, then this must be the trigger part 50 of the rear feeder 10 is moved to the left. In doing so, the Displacement movement against the force of the spring 30 of the rear intake device 10, wherein the spring 30 is tensioned. At the same time, the damper 20 of the rear intake device 10 is pulled out. The driver 61 takes the shutter 50 so long until the rear retractor 10 is brought into the second parking position. This parking position corresponds to the representation according to FIG. 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 middle position, it first encounters the stop 53 of the rear feed device 10 and is caught by it. Under the action of force, the triggering part 50 of the rear intake device 10 can now be deflected out of the second parking position. Then, the spring 30 and the damper 20 of the rear retractor 10 is effective and pulls the sliding door in the in FIG. 8 middle position shown. The sliding door is now trapped again at its driver 61 between the two stops 54 (rear feed device 10) and 54 (front feed device 10). If the sliding door is now moved further to the right, the spring 30 of the front intake device 10 is loaded and tensioned. The damper 20 is pulled out until the operating position according to FIG. 7 is reached. Then the sliding door can be moved in the freewheel further to the left.

The pair of figures 8 and 9 shows the switching operation, wherein the driver 61 is transferred from the cam receiver 56 of the front feed device 10 to the cam receiver 56 of the rear feed device 10.
