Description

The present invention relates to a system for damping the relative movement between device parts.

Specifically, it is about the mechanical damping of movements such as flaps, drawers or doors, especially cabinet doors, such as sliding doors, and furniture-independent doors, especially sliding doors, such as in room dividing systems, or in shower cubicles. Cooling devices, for example in large grocery stores and supermarkets, may also have corresponding door systems, in particular sliding door systems.

It has long been known to mechanically dampen movements, for example, to dampen the displacement movements of a furniture drawer or a sliding door. This is to prevent a drawer or sliding door from being opened or closed excessively quickly because of a too violent operation, and to interfere with a respective end stop with noise and shocks. Such misuse can be caused by lack of awareness, but also by false intuitive assumptions about the loading state of the drawer or the mass of the door and thus too large forces in the operation.

Also, it may be desirable to have a heavily loaded drawer, which must be accelerated due to the inertia with a certain force to start a closing or opening movement, not to drive unattenuated or unrestrained in the opposite position. Especially with heavy sliding doors greater forces are required to accelerate the door, it is uncomfortable for the user to have to catch the door manually before the end stop.

Concretely, it is also known to provide two damper devices, for example, on the same sliding door to dampen end phases of sliding door movement relative to, for example, a cabinet or a room wall at two spaced apart end positions, for example, a first damper device is responsible for a closed position of the sliding door and a second damper device for a fully open position.

Such prior art damper devices have fluid cylinder damper, wherein concretely pneumatic cylinder damper are common, which lead a piston in a cylinder and use the air flows occurring during relative movements for damping. One end of the cylinder damper can be connected to one of the device parts and the other with a coupling part for making and releasing a connection with the other of the device parts.

For example, the damper device may be mounted on a sliding door and the distal end of a piston rod connected to the coupling part. The coupling part in turn can be designed to catch and release a complementary coupling part on the part of a holding and / or guide rail (rail profile) of the sliding door, which is fixedly mounted on a furniture part or a wall. Thus, the final phase of the sliding door movement may be damped in the vicinity of one of the outermost positions of its moving distance, in which the coupling between the two complementary coupling parts is exactly in this section and the coupling parts release each other when the sliding door leaves the section.

By the way, the term "end" does not necessarily mean an end in the geometrical sense. It is much more about attack points relative to the relative movement between the piston and the cylinder, that is, a fixed connection to one of them.

Examples of the structure of such a damper can be found in the WO 2006/056606 ,

Analogous considerations apply to many other applications, such as the opening and closing of other movable furniture parts such as doors or flaps, for casement or room and front doors in draft and for shutters, especially for furniture, etc. These areas are conceivable and preferred, but not exclusive Areas of application of the invention explained below.

The invention is based on the technical problem of specifying a damper system with two damper devices, each of which has a fluid cylinder damper and a corresponding coupling part, with extended applications.

According to the invention, a damping system of the prescribed type is provided for this purpose, in which the two fluid cylinder dampers are at least partially arranged side by side with respect to their longitudinal extent.

The basic idea of the invention is to arrange the two fluid cylinder dampers not in succession but side by side (in any direction perpendicular to the direction of movement) with respect to the direction of movement to be damped and thus the direction of the cylinders and piston rods. For the example of a sliding door, with a corresponding side edge of the mentioned Moving direction corresponds, for example, that not as in the prior art, a damper device and thus a fluid cylinder damper at one end of this side edge (for example, top left) and the other damper device and thus the other fluid cylinder damper arranged in the movement and edge direction spaced therefrom is, in particular at the opposite end of the side edge (for example, top right), but that the two fluid cylinder damper in a viewing direction perpendicular to the movement and side edge direction overlap. This viewing direction can be perpendicular to the sliding door level, which is then spoken of "side by side" in the following; but it can also, for example, perpendicular to the direction of movement and perpendicular to the sliding door plane, which is hereinafter referred to as "one above the other", but belongs to the concept of "side by side" as well as transitions between them. This applies analogously to other moving parts of the device.

With this measure, the total structural length, which is needed for both fluid cylinder damper and also a total of both damper devices can be shortened. (In this case, the length is related to the direction of movement.) This may be in some cases of great advantage, for example, relatively narrow parts of the device (profiles) (specifically the one to which the damper device (s) is / are mounted) or further space requirements for additional devices to be mounted in the above sense "behind" the damper devices. A concrete example are narrow sliding door elements.

Conventionally, the assembly of the damper devices has generally been based on which end of a moving device part, for example a sliding door element, ultimately strikes against another device part in the movement section to be damped. Thus, for example, the damping device for damping a left-hand end section of a sliding door has been mounted on the left in any manner, and accordingly the other damper device on the right, because its purpose is to damp a right-hand movement end section.

However, the inventor has recognized that in many cases this is technically not necessary if the coupling parts, in particular the complementary ones attached to the damping device, are correspondingly cleverly attached. So you can, for example, at a side edge of a sliding door element, or arranged on the two damper devices according to the invention side by side, arrange the complementary coupling part on a wall, a furniture part or a support rail for the sliding door element along the direction of movement at many different positions and thus these coupling parts (each one for each damper device) also position so that the two fluid cylinder damper are at least partially adjacent to each other.

It is not necessary within the scope of the invention, although preferably, as large a part of the length of the fluid cylinder damper side by side (ie overlapping in the mentioned vertical line of sight) to arrange. In individual cases this depends on the available length. However, it is preferred that the two fluid cylinder damper over at least 50%, preferably 60%, 70%, 80% and more preferably 90% of their longitudinal extent are arranged side by side.

Basically, this applies, as already mentioned, for an arrangement laterally side by side or one above the other or transitions therebetween.

The fluid cylinder damper in the invention preferably pneumatic dampers (with cylinder and piston moved therein with piston rod), but may for example also be hydraulic damper or gas spring. The already mentioned WO document is closer to a favorable design.

Furthermore, the two fluid cylinder damper are preferably identical to each other. This is preferably true for the entire damper devices.

The two damper devices may also be mounted in a common unitary mount. For example, as the embodiment shows, they may be mounted on a sliding door member, for example, by means of common retaining cuffs embracing both damper devices.

Furthermore, the fluid cylinder damper and preferably the entire damper devices may be oriented inversely to each other. Thus, for example, if the piston rod of one fluid cylinder damper points to the left, then the piston rod of the other preferably points to the right. Accordingly, in particular in the case of identical construction, the coupling parts on the damper devices can be significantly offset from one another, which can be advantageous in terms of the arrangement of the complementary coupling parts and in particular can also reduce the risk of undesired collisions between these coupling parts.

Preferably, both damper devices each have a pull-in spring, for example a helical spring, which is to be damped in the spring Movement direction or vice versa acts. This retraction spring can be tensioned when moving out of a device part from an end position, while the two coupling parts are coupled together, and then later in a return to this end position parallel to the damping effect ensure that the moving device part is safely pulled to the final position. Such pull-in springs are known per se. In the context of this invention, they are preferably mounted parallel and eccentric to the fluid cylinder damper and thus easily accessible for mounting and dismounting.

In particular, they can be mounted in favor of a particularly compact design on the side of the fluid cylinder damper, on which the coupling part is arranged. For the sake of illustration, reference is made to the exemplary embodiment. This arrangement can be made more compact than when the pull-in spring is arranged, for example, on the opposite side or elsewhere where the corresponding width or height is added to that of the coupling part.

In general, in most applications of this invention will be sought to realize the damper devices particularly slim in order to arrange them conveniently side by side. The term "slimming" also refers primarily to the direction in which the word "next to each other" is to be understood. Such a slim design is well possible with the fluid cylinder dampers discussed here.

Two arrangements are particularly preferred. In a first, the pull-in springs and the fluid cylinder damper are consecutively "in a plane" that they follow one another in this plane, preferably the pull-in springs on the outside and the fluid cylinder damper inside, so that the fluid cylinder damper next to each other and their respective associated Einziehfedern are adjacent. Such an arrangement can in a certain dimension, namely the direction of the "side by side" and the direction of vertical dimension, cause a particularly small size, so it is very flat, and offers in the outer layer of the springs a particularly direct access to them.

Alternatively, the fluid cylinder dampers may be juxtaposed and the pull-in springs in a direction perpendicular thereto, respectively adjacent to them. Then, the pull-in springs are each preferably arranged on the same side with respect to the fluid cylinder dampers, that is to say next to one another (the two fluid cylinder dampers also being adjacent to one another next to one another). With this arrangement, a comparatively compact design can be realized in both dimensions perpendicular to the direction of movement.

As a coupling part of the two damper devices a longitudinally displaceable in a guide receiving tab is preferred, which is connected to the piston rod of the fluid cylinder damper and designed to receive a catch pin as a complementary coupling part. The receiving latch can have a (in a viewing direction transverse to the direction of movement) approximately U-shaped configuration in order to grip the catch pin on the one hand and on the other hand make a good fit with the catch pin on both sides with respect to the direction of movement.

In order to release the catch pin in an extended position of the piston rod along the guide rail, the receiving bolt can retract into a path section that is somewhat curved and / or bent relative to a straight part of the guide rail, in order to reach a latching position there. In this locking position he holds the piston rod and the parallel acting pull-in spring in the extended position of the piston rod.

Incidentally, embodiments of the fluid cylinder damper are preferred in which the damping effect occurs predominantly in one direction and the other direction of motion remains comparatively less or undamped. Although a certain minimum of damping will be necessary in this second direction anyway, if the damper directly participates in the corresponding movement, by the compensating fluid movements. However, this dimension can be kept relatively small by the design of the corresponding flow paths. In particular, the damper may have a one-way valve for "unlocking" the undamped direction of movement.

The invention particularly relates to sliding door systems, ie door systems, in which the door element or door leaf is translationally displaced in order to close or release the door opening.

Sliding door systems are used in furniture construction, in room or front doors, in room dividers, also for the demarcation of walk-in cabinets, refrigerators or rooms, but also for larger hall doors, garage doors, bathrooms, shower cabins u. Ä.

It is advantageous to damp parts of the sliding movement of a sliding door element by a damper. This concerns in particular the sliding door movement in the vicinity of the limits of the movement distance, ie the stops. Here should be avoided that sliding door elements, especially heavy sliding door elements, as a result of their movement by hand or by a technical drive and their resulting kinetic energy strike or slowed down too much. An undamped impact can lead to unpleasant noises and also mechanical loads, whereas a damped movement can be quieter and mechanically gentler and gives the user the impression of a higher-quality execution.

Sliding door systems are in many cases also subject to aesthetic requirements, which must be taken into account.

The invention is thus also directed to a sliding door system according to claim 11.

The basic idea of the invention is that rails are provided in the vast majority of sliding door systems that not only hold the sliding door element, but also cover and cover a space above or next to the corresponding side edge of the sliding door element with a rail leg. Here, the viewing direction on the sliding door element, that is perpendicular with respect to its areal extension, meant. "Holding" here does not necessarily mean that the rail carries the entire weight or even only the weight of the sliding door element, but also refers to those cases in which the rail, for example, only against unwanted lateral movements, so to speak in the mentioned direction, provided is and as far as the sliding door element stops in the track.

The rail can with its leg cover the side edge itself and cover or, as seen in the horizontal direction, connect substantially to the side edge. Then it covers a space above the side edge, the u for mounting element u. Ä. Use and therefore should be protected from view. Of course, there may be a small slot, so that the term covering only in the sense of a substantially covering is to be understood.

Now, if this rail is also used to cover the damper system itself by placing it within the rail, deteriorations of the external appearance by damper constructions can be avoided. For this, the rail must at most have slightly larger dimensions than otherwise necessary. However, it has even been found that in the context of preferred embodiments of this invention, slim designs are possible, in particular by linear cylinders, which can be readily installed in existing standard rail systems.

Preferably, the damper is mounted between the rail and the sliding door member. Preferably, even with other profile shapes, a mounting "on" the sliding door element, ie between a horizontal leg of the rail or its upper wall, and the sliding door element. Also preferred are rails in an inverted U-shape, which thus have a further vertical leg relative to the described L-shape. It is further preferred that the damper is mounted in a solution according to the invention in an upper rail, although sliding door systems usually also additionally have lower rails in the bottom area.

The rail may include bearings for supporting the sliding door member in the slidable manner in the rail, such as systems having guide rollers and treads therefor. This applies both to the already mentioned case that the holding by the rail corresponds only to a lateral guiding in a web, as well as in the case of a support of a part of or the entire weight of the sliding door element.

Finally, in the context of the invention, an application in the field of sliding door systems with particularly narrow sliding door elements, as they occur in room dividers, sections of walk-in cabinets, gates and room and front doors, is preferred, ie outside the actual furniture. Accordingly, it is preferably aimed at sliding door systems which are mounted on room (including bathrooms) or house walls.

In the following, the invention will be explained with reference to various exemplary embodiments, wherein the individual features disclosed may also be essential to the invention in other combinations and implicitly, as already mentioned, relate both to the device categories and to the use category of the invention.

1 shows a perspective view of a damper system according to the invention as a first embodiment.

2 shows a side view with a section of a sliding door system according to the invention and the damper system 1 ,

3 shows a side view accordingly 2 with another moving position of the sliding door system.

4 shows a further side view corresponding to the 2 and 3 with still another movement position.

5 shows a variant of the damper system 1 as a second embodiment.

6 shows another variant to the 1 and 5 as a third embodiment.

1 shows two reversely arranged pneumatic cylinder damper, of which only the front 1 to recognize and the rear is hidden. The damper 1 has in the 1 right area a pneumatic cylinder and left of it a guide rail 2 , In the guide rail is a receiving bar 3 led accordingly 1 seen from left below has a U-shape. 1 also shows a fishing pin 4 that of the recording bar 3 is gripped and attached to a mounting plate 5 hangs.

Further, on the receiving bar 3 to the right a funnel-shaped receptacle for holding a button-like end of a draw-in coil spring symbolically shown as a cylinder 6 provided, the other button-like end to a corresponding fork 7 at the opposite end of the cylinder of the damper 1 hangs.

Thus, a damper device is formed, which is provided a second time behind the damper device just described, but in the reverse position.

From the rear damper device can be seen in 1 the draw-in coil spring 6 ' , the recording bar 3 ' , the associated catch pin 4 ' with mounting plate 5 ' , the fork 7 ' and, far right, a small end piece of the guide rail 2 ' , This tail corresponds to the left end piece of the front guide rail 2 a bent relative to the longitudinal direction of the damper and curved trajectory section. In this trajectory section of the recording bar 3 respectively 3 ' retract and held there in a locked position, in which case the catch pin 4 respectively 4 ' is released. The fishing pin 4 may move further to the left relative to the damper devices and the catch pin 4 ' to the right. In a return movement, they engage in the right leg of the receiving bolt 3 or the left leg of the receiving bolt 3 ' and release the respective receiving latch from the locking position, so that he back into the straight section of the guide rail 2 respectively 2 ' arrives.

The damper devices correspond, so far described, largely the damper device from the already cited WO 2006/056606 except for the fact that the pull-in springs 6 and 6 ' on the side of the recording bar 3 and 3 ' are provided and not on the opposite side to it. The damper devices are built very slim overall and, as I said, in contrast to the WO script double and side by side provided.

It can be seen clearly that the catch pin 4 a front track matching the front damper device moves away (as it moves along the direction of travel) and the catch pin 4 ' a track matching the rear damper device. Both fishing pins 4 and 4 ' are above their mounting plates 5 and 5 ' attached to the same device part, namely, as 2 still shows in detail, on a support rail of a sliding door system. You can basically go into and out of engagement with the picking bars independently 3 and 3 ' come and do not disturb each other. At the same time the two damper devices together need the same length as each of them and have an overall width still suitable for mounting on a sliding door element. To this assembly are end-side cuffs 8th and 8th' provided, namely in 1 left and right, each encompass and hold the portion of a guide rail of a damper device and the corresponding opposite end of the damper cylinder of the other damper device. The sliding door element must be in accordance with 2 to introduce underneath.

2 shows a side view of the damper system 1 , In 2 one recognizes further a sliding door element 9 (the door leaf) under the damper system and a retaining rail 10 , which reversely overlaps and covers the damper system in a U-shape (and in FIG 2 cut and shown in plan view of the rear leg of the U). A detail difference is that here both fishing pins 4 and 4 ' are out of engagement with the damper system. Specifically, the left catch pin is 4 to the left of the left-hand receptacle 3 and the right pin 4 ' right of the recording bar 3 ' , with both recording bars 3 and 3 ' are retracted into the already described trajectory sections at the end of their respective guide rail. The sliding door element 9 is opposite the rail 10 versatile. For example, if it is moved to the left, the left guide pin comes 4 again in engagement with the receiving bar 3 , whereupon the draw-in spring 6 the sliding door element with simultaneous damping by the damper 1 pulls into the final position, like 3 shows. 4 shows the opposite situation, ie the right end position of the sliding door element 9 ,

You can easily see that by a greater distance between the pins 4 and 4 ' allow larger free movement distances to be created and in 1 there is no free movement path This does not require the arrangement of the damper devices in the damper system be changed. This arrangement is how the 2 to 4 show, for the very narrow sliding door element 9 advantageously short (relative to the direction of movement, ie the horizontal direction from left to right in the figures).

5 shows a variant, here without pegs. Here are the recording bars 3 and 3 ' laterally outwards and not upwards, the pull-in springs 6 and 6 ' as well as the dampers 1 and 1' So, so to speak, are arranged in a row next to each other in a row, with the pull-in springs facing outward. They are easily accessible in all embodiments and easy to hang. By their arrangement on the same side as the recording bar 3 . 3 ' the width is also low in this dimension.

Incidentally, the explanations to the previous figures apply. The fishing pins 4 and 4 ' according to 1 could be arranged slightly deeper and with a slightly greater distance from each other in the horizontal direction and transverse to the direction of movement or rotated by 90 ° so to speak laterally engage from outside. The structure of this damper system is shallower than that of the first embodiment, but wider in the horizontal direction transverse to the direction of movement. The mounting collars are completely or largely identical to those of the first embodiment.

Another variant shows 6 as a third embodiment. Here are the dampers with slightly different mounting collars 8th'' and 8th''' mounted one above the other, with the receiving latch 3 and 3 ' show again laterally outwards, to opposite sides. Of course, they could both be directed to the same page.
