In the drawings, reference numeral 1 indicates a damping and Feeder for sliding doors called.

The damping and retraction device according to the invention comprises one Energy store, according to the illustrated embodiment and Figures 18b and 21b consists of a spring 2, and a damper 3, as also from the the aforementioned figures can be seen.

The energy accumulator 2 is tensioned during the opening process of a sliding door its stored force is used as a pull-in aid in the closing process final closed position used. The damper 3 is shortly before reaching the final closing position is one of the direction of the closing forces counteracting and damping the closing movement applied counterforce.

Energy store 2 and damper 3 have a common housing 4 and one common push rod 5, which protrudes from the housing 4.

The housing 4 is attached to a carrier 6.

At the front, free end of the push rod 5 is a transmission member 7 in shape connected to a bracket. At the other end of the transmission link 7 is one Driver and control device 8 connected, which opposite the carrier 6 is mounted longitudinally on this.

An actuator 9 which can be fastened on the door side is located between the closed position and a predetermined opening position of a sliding door in Driver connection with the driver and control device 8 and after Exceeding said predetermined opening position Driver connection automatically canceled and the driver and Control device 8 blocked with respect to the carrier 6.

The energy accumulator 2 is then prestressed in this position. Becomes a sliding door now moved back into its closed position, the actuator 9 arrives again in engagement with the driver and control device 8 with respect to their blockage with respect to the carrier 6 released and can again in Move your starting position back. The pre-stored relaxes Lift mechanism 2. The force released in the process can be used as a pull-in aid for the Movement of a sliding door can be used in its final closed position. On The damper 3 prevents the sliding door from striking too hard.

In the following, the individual figures of the constructive structure of the damping and retraction device 1 explained in more detail.

The carrier 6 is preferably made of plastic Molding, which has a substantially rectangular basic shape and on has its outer longitudinal edges locking means 6a, which for provisional Determine the carrier and thus the total damping and Feed device 1 on a running rail 10 serve a sliding door. How out 12a to 12c, the latching means 6a of the carrier 6 can do this be used, the entire damping and retraction device for example to lock in screw channels 10a of a guide rail. Then the Carrier 6 with a guide rail 10, for example by screwing connected.

The connection between the carrier 6 and the housing 4 is made by on Carrier 6 formed locking clips 6b, which are provided on the housing 4 Reach over locking ribs 4a and by at an end face of the Housing 4 molded retaining ribs 4b, which run parallel to each other and form a receiving groove 4c between them, into which the face end Limiting area 6c of a recess 6d of the carrier 6 engages, so that Housing 4 is secured against lateral displacement relative to the carrier 6.

An axial fixing of the housing 4 with respect to the carrier 6 can be done by additional gluing, screwing or the like can be made.

The attachment of the housing 4 to the carrier 6 described above is easy to assemble and overall under Cost aspects very cheap.

The type of fastening described is particularly clear from FIGS. 4 and 20 out.

FIG. 4 also shows very clearly that the driver and control device 8 is formed in several parts and from a control disc 8a and one Drive plate 8b, which can be connected to one another by means of a screw 8c are.

The control disk 8a is on its side facing away from the driving disk 8b equipped with a journal 8d, one at its free end has radially projecting nose 8e. This journal 8d passes through Carrier 6 in the region of a longitudinal slot 6e, which at an end end has an extension 6f, which pushes through on the journal 8d provided projecting nose 8e allowed. The bearing pin 8d with its molded protruding nose 8e is through a keyhole opening 7a of the transmission member 7 inserted into this keyhole opening 7a and through Twisted axially secured by a predetermined angular amount, in that the projecting nose 8e of the journal 8d on the outside on the Transfer member 7 rests.

The control disc 8a is otherwise in a recessed guide groove 6g of the carrier 6, which widens conically at one end.

The drive plate 8b is in the assembled state with the control plate 8a non-rotatably connected. The drive plate 8b has a recess 8f, into which an actuator 11 fastened on the door side can engage, see here in particular the figure 18c.

Figures 15 to 17 clearly show the assignment and mounting position of a Guide rail 10 in relation to a piece of furniture, it being clear that the Guide rail 10 on the top floor 12 of a piece of furniture, not shown is fixed and by the area projecting beyond this top floor a sliding door 13 is covered. Thus, the complete damping and Feeder 1 completely hidden from the visible side of the furniture appropriate.

16 shows a sliding door 13 in a closed position. In this As already described above, the closed position engages with a door-side fastener Actuator 9 in the recess 8f of the drive plate 8 b. In this Closed position is the energy accumulator 2 designed as a spring within the Housing 4 relaxes, as shown in Figure 18b.

If the sliding door 13 is now opened, the actuator 9 is used to open the door Driving plate 8a taken and the transmission member 7 Pull rod 5 pulled out of the housing 4. The energy accumulator 2 stretched by squeezing.

At the end of the possible displacement path of the drive plate 8b, the is predetermined by the dimensioning of the longitudinal slot 6e within the Carrier 6, the drive plate 8b is forcibly around a predetermined Angular amount rotated so that the actuator 9 of the recess 8f Driving plate 8b can leave. At the same time, Control disc 8a rotated by the same amount of angle. In this position then the control disk 8a supported on the conically enlarged area of the Guide groove 6g of the carrier, whereby the control disc 8a and thus the entire driver and control device 8 is blocked relative to the carrier 6. In this possible end position, the energy accumulator 2 is maximally prestressed. If the sliding door 13 is now pushed back into its closed position, so shortly before the final closed position, the actuator 9 comes back in Contact with the drive plate 8b. The actuator pivots through its movement in the closing direction the driving plate 8b back into its Basic position, the same applies to the control disc 8a. In this basic position, the control disc 8a again in the guide groove 6g of the Carrier 6 are moved. Through the stored and now released force the closing movement of the sliding door 13 is within the energy accumulator supports and ensures self-retraction, even when the outer ones are on the sliding door 13 applied forces do not bring about a final closing could. The damper 3 is too violent slamming at the same time or striking the sliding door 13 prevented in its final closed position.

In the illustrated embodiment, the damper 3 is a known damping cylinder, in which case the push rod 5 the Piston rod of this damping cylinder forms and the housing 4 from the Cylinder tube of the damping cylinder exists.

Alternatively, dampers of different design can of course also be used can be used, for example, rotationally or piston-damped Elements are used, the push rod 5 then, for example, as Rack for actuating a rotationally damped element is formed.

The use of a fluid damper with a gas or liquid filling, as shown in the illustrated embodiment has the advantage here to be able to use commercially available damping elements and practical arrange a spring as a force accumulator 2 in the cylinder tube of the damping element to be able to.

It can be seen from FIGS. 22a to 22f that the damping and Infeed device in the simplest way against incorrect operation is secured. The said figures make it clear that the drive plate 8b in the area of your recess 8f on one side of this recess 8f by a resilient tab 8g rising in the closing direction of the sliding door 13 Is provided. Provided that a condition is caused by incorrect operation of any kind Has been brought about in which the driver 9 is not in the closed position in the Recess 8f engages when the sliding door 13 is closed again Slide actuator 9 over the resilient tab 8g, this after Press down and after re-entering the actuator 9 in the Recess 8f will spring back the resilient tab and thus again form a system for the actuator 9, so that now with a renewed Opening the sliding door, the driving plate 8b can be carried along correctly can.

FIGS. 22a and 22b show a maloperation state, FIGS. 22c and 22d show the sliding of the actuator 9 over the resilient tab 8g and Figures 22e and 22f make it clear that after this sliding over the resilient tab 8g and the engagement of the actuator 9 in the Recess 8f springs back the resilient tab 8g and a system for the Actuator 9 forms.

In the illustrated embodiment, the damping and retraction device 1 mounted on a running rail 10 of a sliding door 13 and that is on the door side required actuator 9 attached.

Of course, a kinematic reversal of this type of installation is also conceivable, i.e. the damping and retraction device 1 can also be mounted on the door side accordingly, there is then an actuator 9 on a guide rail to be arranged stationary.

The carrier 6 is advantageously designed as a molded plastic part and such symmetrical that both left and right hand assembly - based on the arrangement on a corresponding piece of furniture - is possible.

The control disk 8a and the driving disk 8b are also advantageous formed as plastic molded parts.

The bow-like transmission member 7, which when opening or closing a sliding door 13 must transmit forces, however advantageously made of metal.

As can be seen particularly clearly from FIG. 11 a, the guide rail 10 is in the Mounting area of the damping and retraction device 1 with an elongated hole 10a equipped, the length of which is at least the maximum displacement of the Push rod 5 corresponds. When installing the damping and Feed device 1 on this rail 10, the drive plate 8b of the Control disc 8a initially separated, so that now the carrier 6 on the back of the Rail 10 can be attached. Then the drive plate 8b connected again to the control disk 8a by the screw 8c.

Deviating from the exemplary embodiment shown, it would also be conceivable instead of the elongated hole 10a, one from the relevant end face of the rail 10 to bring outgoing slot into this rail 10, this would then be conceivable in the assembly of the damping and retraction device 1 so proceed that all components of this damping and retraction device 1 be completely preassembled, as the fully preassembled ones are now inserted Driver and control device 8 is possible in this slot.
