Description

The present invention relates to a sliding door arrangement according to the preamble of claim 1.

In sliding door arrangements of the known type hitherto in the areas where two sliding sash can collide with each other, glued to the sliding sash plastic or rubber buffers used, which indeed mitigate a shock of two meeting sliding sash, but is disadvantageous here to consider that it is usually a unwanted springs of the sliding sash can come. Another disadvantage is that the known from the prior art collision protection devices are in the visible range of the user and thus produce a disturbing visual effect. This has hitherto been realized, for example, by a cover strip on a sliding sash or by differently shaped end edge contours on the sliding sashes in order to cover the butt joint.

The US Pat. No. 6,487,752 B1 discloses a sliding door arrangement in which a spacer is provided between two sliding doors, which is intended to prevent a hard hitting the sliding doors together. Other sliding door arrangements with a collision protection show the WO02 / 36916 A1 and DE 20 2008 014 529 U1 ,

The present invention has for its object to improve a sliding door assembly of the generic type such that a practical collision protection device is realized.

This object is achieved by a sliding door assembly with the features of claim 1.

The arranged in the supporting and / or guide rail spacer can be easily profiled so that it can not fall out of the rail after insertion into one of the rails and thus is initially arranged captive in the rail area. In addition, it is advantageous that the spacer by the arrangement within one of the rails of outside, that is, when looking at the front surface of the sliding sash, is virtually invisible.

A collision of the two sliding sash is reliably prevented, since the length of the spacer, the minimum distance between the two sliding sashes, regardless of the position of the sliding sash is determined by the inventive solution constructive.

A preferred embodiment of the invention provides that the sliding leaves are guided by means of supporting parts in the support rail and by means of guide members in the guide rail and that the at least one collision protection device is in the displacement line of the support and / or guide parts.

This ensures that the spacer to prevent a collision of both sliding sash does not impinge directly on a front edge of a sliding sash, but always on corresponding abutment portions of the support or guide parts which are attached to sliding sashes, not to damage the sensitive end edges of the sliding sash. A preferred embodiment of the invention provides that the collision protection device cooperates with a coupling device, wherein the coupling device cooperates with a sliding leaf and the spacer with the other sliding leaf. Optionally, the coupling device may be equipped with a damper. Furthermore, the coupling device can be equipped with either an energy storage, such as a mechanical or a gas spring. Alternatively, a coupling device without energy storage can be used.

This ensures that not only a collision of both sliding sash is effectively prevented, but also that the corresponding components of the collision protection means a Mitfahren or ride, that is a carryover later in the process of a sliding sash avoids the desired position of these sliding sash is not changed ,

In a corresponding construction with coupling device, it is expedient if the collision protection device is provided next to the spacer on the one hand with a locking tab designed as a locking element for coupling with a sliding leaf and on the other hand with an activator for actuating a arranged on the other sliding panel driver of the coupling device.

In a construction without a coupling device, the activator of the collision protection device can be replaced by a clamp into which a counterpart of the support and / or guide part can be inserted and possibly fixed on the other sliding leaf.

As a result, coupling devices and optional damper devices of known type can be used, as used in furniture, for example, in drawers or the like.

Further features of the invention are the subject of further subclaims.

Embodiments of the invention are illustrated in the accompanying drawings and will be described in more detail below.

In FIG. 1 is a sliding door assembly with two sliding panels 1 and 2 shown in perspective, which are guided via support members 3 and 4 in a common lower support rail 5 and guide parts 6 in a common upper guide rail 7.

The support members 3 and 4 are as well as the guide members 6 preferably made of metal or a stable plastic or a combination of these materials and in each case near the corner regions of the sliding sash 1 and 2 attached thereto. In the area of the lower support rail 5, the sliding door arrangement is provided with a collision protection device designated overall by the reference numeral 8 (see Fig. 5 ), in the region of the upper guide rail 7 is optionally another collision protection device 8 'arranged (see Fig. 4 ), wherein the arranged in the upper part of the sliding door arrangement collision protection device 8 'consists solely of a spacer 9 which is longitudinally displaceable in the upper guide rail 7 and designed in the form of a sliding block so that this spacer 9 does not fall out of the upper guide rail 7 can, but only longitudinally displaceable within this guide rail 7. The Distance of the sliding sash 1 or 2 is given by the system of the end faces of the collision protection device 8 'to the projections of the guide parts 6.

The particular in the Figures 10 and 11 shown lower collision protection device 8 has in addition to a spacer 15 is still designed as a locking tab 11 locking element and an activator 12 in the form of a projection, which allow a coupling with the one and / or the other sliding sash 1, 2. In this case, preferably, the collision protection device is integrally formed, but it is also conceivable, the spacer 15, the locking tab 11 and the activator 12 composed of individual elements to a collision protection device 8.

This coupling can be achieved for example by locking with the support member 4 of the sash 1 when first merging sliding sash 1 and anti-collision device 8, in which case the locking tab 11 of the collision protection device 8 is run over, so that a permanent coupling between said support member 4 and the collision protection device 8 is brought about.

The said locking tab 11 is in FIG. 11 clearly recognizable, it may be pointed out at this point that a coupling of the collision protection device 8 with the sliding leaf 1 can be realized in a different manner than on the latch described. For example, the collision protection device 8 can be firmly fixed to the sliding leaf 1 by means of screws or other means, by means of clips or the like.

On its side facing away from the locking tab 11, the collision protection device 8 is provided with an activator 12, which is provided for actuating and controlling a coupling device 16, wherein the coupling device 16 is attached to the second sliding sash 2, as the Figures 5-8 make it very clear. About this activator 12, the coupling device 16 is actuated when approaching the two sliding sash 1 and 2 together by a driver 17 is brought to the coupling device 16 into engagement with the activator 12. Preferably, a damper 13 is arranged on the coupling device 16 so that the forces acting in the closing direction are damped and a soft merging of the two sliding leaves 1 and 2 is guaranteed in their smallest distance from each other. Furthermore, the coupling device 16 is preferably equipped without a mechanical or a gas spring in order to prevent the separation of the one sliding leaf from the other sliding leaf the respective other sliding sash is not moved. However, in other structural design or by additional elements, such as a brake on the support member 3, the coupling device 16 are also equipped with such a spring element.

Preferably, the coupling between activator 12 and driver 17 is not permanent, that is a decoupling is easily possible at any time during which the coupling between the locking tab 11 and the support member 4 is permanent after the first snap.

In the embodiment of the invention according to the Figures 1-8 is achieved by the collision protection device 8 in the lower area when closing the sliding sash 1 and 2, a damped impact, while the optional collision protection device 8 'in the upper region of the guide rail 7 only allows an undamped shock.

Of course, it is also conceivable to realize in the lower part of an undamped version, provided that the forces to be expected when merging the two sliding sash 1 and 2 are not too large.

A damped design can be realized both in the region of the lower support rail 5 and in the region of the upper guide rail 7, it is also possible to provide a collision protection device 8 exclusively in the region of the lower support rail 5 or exclusively in the region of the upper guide rails 7.

In this case, it is essential that the collision protection device 8 has a spacer 15, which lies in the sliding region of the sliding leaves 1 and 2, preferably in the region of support and / or guide parts, since these are made of stable material and thus damped or even Undamped shocks can absorb well, the front sides of the sliding sash 1 or 2 are not damaged.

The FIGS. 12 to 15 show yet another embodiment of the invention, in which the collision protection device 8 is provided instead of an activator 12 with a clamp 14. This embodiment is used when no coupling device 16 is provided for the sliding door arrangement. In this spring-loaded clip 14 may run into a correspondingly shaped counterpart of an opposite support member 4 and optionally also be secured. The FIGS. 14 and 15 clearly show how the two sliding sash 1 and 2 are kept at a distance by the collision protection device 8, when a coupling of the respective coupling elements is done. The geometry and the function of the locking tab 11 is analogous to the previous embodiment. The coupling between the bracket 14 and the counterpart of the support member 4 is solvable at any time without much effort.

In the embodiment according to the FIGS. 12 and 13 is an attenuation of the shock only by the entry delay due to the friction in the bracket 14 possible.

In summary, it should be mentioned again which possibilities are possible and conceivable in the context of the present invention in order to avoid a collision between two sliding leaves 1 and 2 which can be moved in a common plane:
In the simplest case, a spacer 9 can be arranged between the two sliding sashes 1 and 2 either in the lower or upper guide region, which prevents a meeting of the two sliding sash 1 and 2.

It may be a spacer as described above but also provided both above and below.

The collision protection device 8 may be equipped with a damping, wherein such a collision protection device 8 in turn can be implemented either in the lower, in the upper or both in the lower and in the upper guide area.

In all cases, the advantage is to be seen in the fact that in each case a visually appealing, since the collision protection device 8 covering construction is realized.
