Description

Device for drawing in and damping a sliding door carried in a profile rail for guiding drives into the end position

The invention relates to a device for drawing in and damping a sliding door carried in a rail for guiding drives according to the preamble of patent claim 1.

For some time, there has been a desire that sliding doors held in their end position on the one hand and on the other hand drawn on the last displacement distance in the end position and, if hit at high speed in the end, also damped, i. slowed down to avoid a hard impact.

From the state of the art a variety of retraction and damping devices are known. Often these are housed in a common housing, ie the feeder element is not separated from the Dämpfungselernent, but can be installed as a unit in cabinets. In the best known embodiments, the damper and retractor, which is housed in a common housing, either side of the rail attached to the ceiling or attached as for example in EP-A2-1 426 535 laterally at the end of the rail. Both versions are clearly visible when the sliding door is open and if the upper rails are embedded in the ceiling, the housing of the device acts coarse and it may even hinder the insertion of books or folders on the top shelf.

An object of the present invention is to provide a device for drawing a sliding rail carried in a rail from the drive in the end position and also to slow down the speed of the impact on the end position sliding door, which is installed within the cross section of the rail.

This object is achieved by a device according to the features of patent claim 1.

Advantageous embodiments of the device are described in the dependent claims.

It is possible by the series-connected collection device and damping device to accommodate them in a very slim housing, which finds room within the cross section of the rail in which roll the rollers of the drive. Another significant advantage of the device is that it is not attached to the rail or the cabinet, but is slidably mounted together with the drive in the rail and therefore at any time, not even when the sliding door is visible from the outside. It always stays hidden behind the sliding door. The device can be inserted with the drive in the rail.

In the further advantageous embodiment of the invention, the housing which receives the means for damping and retraction, narrower than the width of the slot on the underside of the rail. This makes it possible to subsequently introduce or remove the drive together with the device for damping and retraction on a already mounted on the ceiling of a cabinet or room rail. What is needed is either either a notch over a range of a few centimeters on the underside of the rail or a correspondingly short profile rail piece, which is designed to be removable.

Based on illustrated embodiments, the invention will be explained in more detail. Show it

In a longitudinal section according to Figure 1, the device is indicated by reference numeral 1. With reference numeral 3 is the entirety of a LaufWerksanordnung comprising a inserted into the sliding door 5 Auftsähehme 7 and the drive inserted therein 9. The drive 9 is above a roll holder 11 with rollers 13 visible. On the side of the roller holder 11 fastening tabs 15 are integrally formed on both sides, to which the housing 17 of the device 1 on the drive 9 or on the roller holder 11 can be attached. The attachment can be done with one or two pins 19 or attached to the housing 17 cams, which can engage in at least one of the holes 15 on the mounting tabs. There are also other suitable, preferably articulated types of connection possible. At the other end of the housing 17 supporting rollers 21 are fixed, which guide the housing 17 of the device 1, when this is inserted into a C-shaped rail 23, and carry. Enlarged, FIG. 7 shows the profile rail 23 in cross-section with the housing 17 of the device 1 inserted therein.

With reference to Figures 4 and 5, the structure of the device 1 will be described in more detail. The support rollers 21 are mounted on a shaft which is held by a fork-shaped receptacle 25. The fork-shaped receptacle 25 is preferably formed as a plastic part and inserted partially in the end of the housing 17 of the device 1. At the same time inserted into the housing 17 pin-shaped part 24 of the receptacle 25 serves as a holder for a spring 27, the other end to the rear end with a push rod 29 is connected. On the front end of the push rod 29, a two-armed, fork-shaped lever pawl 31 is pivotally mounted in a bore 35 with stub axles 32. At this lever pawl 31 further stub shafts 33 are laterally formed, which slide in a suitably dimensioned guide groove 37 ".

On the housing 17, which has a substantially rectangular, ie box-shaped cross-section, in the two vertical side walls, the guide grooves 37 'and 37 ". These guide grooves 37' and 37" serve to guide the lever pawl 31 and a guide pin 41 formed on the lower arm 39 of the lever pawl 31. The present at least on one side of the housing 17 guide groove 37 'initially runs horizontally, ie parallel to the rail 23. At its front end, the guide groove 37 "is guided approximately at right angles down.

The pawl 31 is located when moving the sliding door 5, if this is not in the vicinity of the end stop, as shown in Figure 9 pivoted forward. The guide pin 41 is then in the vertical portion of the guide groove 37 '. In this position, the upper lever arm 39 'is at an acute angle to the vertical. In this holding position, the spring 27 is in the exploded position shown in Figure 4 under tension. The drive 9 with the sliding door 5 can be moved in this position unhindered in the rail 23.

On the other hand, when the sliding door 5 approaches the end position, the upper lever arm 39 'encounters a resistance, for example a stopper element 43, which is arranged on the profiled rail 23. The stopper element 43 includes a stop edge 45, which projects beyond the upper leg of the rail 23 against the inside. At this stop edge 45, the upper lever arm 39 'abuts when the sliding door 5 is moved to the end position. By the Stop at the stop edge 45, the pawl 31 is pivoted counterclockwise. As a result of the pivoting movement, the guide pin 41 slides upwards on the lower lever arm 39 "in the guide groove 37. The spring 27, which has been held under tension by the push rod 29, can relax, as a result of which the housing 17 (FIG. The sliding door 5 connected to the housing 17 via the drive 3 consequently moves to the right towards its end position.

So that a hard impact in the end position can be prevented, the push rod 29 acts within the housing 17 as a brake / damping element. For this purpose, the push rod 29 and the spring 27 are in a cylinder 47. A arranged on the push rod 29 damping element with an O-ring 49 seals the push rod 29 relative to the cylinder 47 and brakes the movement of the push rod 29 by the back pressure (FIG 5).

Alternatively, instead of an O-ring, a lip seal can occur or a pneumatic or hydraulic damper element can be used. The stopper element 43 comprises in addition to the projecting into the cross section of the rail 23 stop edge 45 in addition to a spaced-mounted thereto Rückschwenkkante 51. Both edges 45 and 51 are arranged on a body, for example made of plastic, by means of a screw or a Rivet is connected to the rail 23. Alternatively to a separate, attached to the rail 23 stopper element 43, the latter can also be generated directly by punching and bending of two tabs 53 and 55. In this case, the tab 53, which is bent into the interior of the rail 23, the stop edge 45 'and formed at a distance thereto tab 55 forms the Rückschwenkkante 51'.

When you open the sliding door 5, the movements of the pawl 31 and the spring 27 done in the reverse direction. Against the resistance of the now relaxed spring 27, the sliding door 5 is moved from the end position. For the time being, the tensioning of the spring 27 takes place, and this is because the latch lever 31 can not pivot through the guide pin 41 which is guided by the guide groove 37 "and, moreover, is held by the return pivot edge 51. The housing moves as a result of this measure 17 to the left, which is connected to the sliding door 5 via the drive 9. The push rod 29, with the latch lever 31 attached thereto, remains as described above, and the spring 27 is pulled apart, ie tensioned, as soon as the guide bolt 41 reaches the vertical section 37 'is reached, the lever pawl 31 is pivoted in a clockwise direction by the force acting on its arm 39' The lever pawl 31 now has room again to move to the left in the rail 23 Tensioned spring 27 is securely held on the push rod 29 and the guide pin 41.

Instead of a spring 27 designed as a tension spring, a spring 27 'designed as a compression spring can be used as shown in FIG. 6. In this embodiment, the push rod 29 completely penetrates the spring 27 and the cushioning member with the O-ring 49 is fixed on the opposite side.

In a further preferred embodiment of the invention according to FIGS 12 to 15, the housing 17 which receives the Einzieh- and damping device is narrower than the width of the slot on the rail 23. This allows the housing 17 in an already mounted rail 23 from below. This requires either a notch of the region of the rail 23 on which roll the rollers 13 of the drive 9 (no representation), or an example 5-6cm long end portion 23 'of the rail 23, which of the ceiling 57, to which it is attached is, is formed detachable. The length of the portion 23 'must be chosen only slightly longer than the longitudinal extent of the drive 9, because the support rollers 21 are easily inserted by tilting the device 1 in an approximately vertical position and then by pivoting the device 1 and the Drive 9 in the rail 23 is inserted.

After insertion of the device 1, the stopper element 43 can be inserted into the rail 23 through the same frontal opening. Thereafter, the (re-) mounting of the removable profile section 23 'takes place. Subsequently, the stopper element 43 can be moved into the profile section 23 moved to the left and secured there. However, the rollers 21 of the drive 9 remain in any position of the sliding door, even in the closed position, within the

Profile rail section 23 ', which is always firmly mounted on the ceiling. A rollover of the joints of the two profile rail sections 23 'and 23 is therefore not carried out. This also excludes a rumble noise.

In contrast to the first embodiment, the elements of the damping and retraction device, which are located within the housing 17 are not described in detail. They may have the same structure or, as seen in Figure 12, be constructed differently in that the spring for retraction is not within the damper element, i. is disposed within the cylinder 47. The spring, not shown in detail in the figures, wraps around the cylinder 47 and is deflected on a roller 59 (FIG. 12).
