EP2129854B1 - Sliding door system - Google Patents

Description

The invention relates to a sliding door system on at least one side of a passage opening of a building, comprising at least one if necessary. One or more telescopic sliding door leaf, and optionally at least one sliding door drive, according to the preamble of claim 1.

Such sliding door systems are well known in the art.

So revealed the DE 19819558 A1 already a lateral drive for a sliding door, as well as C- / U-shaped guide rails above the entire door area, also above the passage opening.

The DE 4430941 A1 discloses a magnetic levitation guide of a sliding door which is relatively expensive.

DE 2306206 A discloses a "cantilever" in the door opening pivoting wing, but no sliding door.

The DE 1954791 U discloses a "self-supporting" in the door opening Schiebegittertor according to the preamble of claim 1 and 7, as well as the DE 10321547 A1 and the parallel and identical ones EP 1477631 A2 ,

The latter two publications disclose an automatic sliding door with at least one horizontally displaceable by means of a drive door, wherein the drive is arranged laterally with respect to the passage opening defined by the closed door and wherein the door in its closed position "free-floating" protrudes into the passage opening. The door leaf can be supported and guided in an advantageous embodiment on the upper lintel or on the ceiling by a U-shaped guide laterally in the depth direction (passage direction). What is understood here exactly under a "free-floating" door within the passage opening is not detailed. A However, support on the floor and / or a suspension on the lintel or the ceiling of the door leaf within the passage opening is not provided.

Disadvantage of all the aforementioned embodiments of the prior art is that they bring either a high degree of assembly work at the installation of the door with it, or as in a particular embodiment of the DE 10321547 A1 respectively. EP 1477631 A2 without upper lateral U-shaped guide, a relatively low stability during the closing operation and in the closed state of the door has, or can not accommodate without tilting due to the side mounted to the guide system door wing resulting tilting moment. Also, weight, drive and tilting moments are absorbed by only one guide.

The EP-A-1 743 824 discloses a sliding door construction for platforms comprising two lateral stationary fixed parts and two sliding doors which shoot synchronously and in opposite directions. The sliding doors have an encircling frame and are designed to be freely supporting, meaning that a small gap of up to 30 mm remains between the floor and the lower edge of the door. For the door two suspensions are provided on the rail side, namely an upper suspension in the region of the upper edge of the sliding doors and a lower suspension in the lowest part of the sliding doors. The lower suspension has a stationary guide element, which is arranged on the fixed part. At the respective door designed as a U-shaped guide rail is fastened, which forms a roller or ball bearing together with the guide element. The guide rail protrudes to the rear beyond the actual width of the door.

For the drive of the doors, an electric motor is provided which via a worm gear, which drives a toothed belt drive roller. In engagement with the toothed belt drive pulley is a toothed belt, which is deflected by two deflection rollers arranged symmetrically above the toothed belt deflection pulleys. The ends of the toothed belt are attached to the guide rail.

The upper suspension has an upper door profile, which is part of the surrounding door frame. At this upper door profile is a Fixed guide rail, which has at least the width of the sliding door. As a fixed element, a guide profile 15 is attached in the upper region of the Fixelements. However, it does not directly engage the guide rail in the guide profile, but the upper guide is designed as a telescopic guide, in which a telescopic profile is movably arranged between these two elements. The telescopic profile is displaceable both with respect to the guide rail and with respect to the guide profile. The use of the telescopic profile allows a particularly large width of the guide.

According to another embodiment, the upper guide is arranged at approximately half the height of the sliding doors. It stabilizes the sliding doors only in the horizontal direction. Carrying in the vertical direction is completely taken over by the lower guide.

The DE-U-201 02 740 discloses a sliding door for closing a wall opening between rooms in the interior comprising two longitudinally offset from each other, up and down arranged mounting rails, which each lead a drive, such as rollers or a carriage. In this case, a support rail is placed above the frame lintel and the other support rail next to the frame in the opening direction leading away above a rubbing strip. The rollers or the carriage are mounted on the wall-side surface of the door leaf on adjustable cantilever plates. To stabilize the door running a hidden play-free floor guide is provided on the floor. Characteristic of the sliding door system of the D2 is that the door leaf is completely supported by the upper mounting rail when the wall opening is closed and by the lower mounting rail when the wall opening is open.

The U.S. Patent No. 5,395,165 discloses a furniture door for a television cabinet, which is first pivoted to open and then pushed back along two parallel guide rails, so that it comes to lie adjacent to the wall.

Object of the present invention is therefore to further develop a sliding door system according to the above-mentioned prior art, that lower Costs regarding installation work at the installation of the sliding door system arise, and that in addition the door has a much higher stability during the closing operation and in the closed state and thus the sliding door system has a longer life.

The solution to these problems are solved by the features of independent claim 1.

It is essential according to claim 1, that a leg of the C- / U- / V- / L-shaped guide profile of the other linear guide carries the weight of the sliding door leaf and thus divide the weight, drive and tilting moments on two guides. In addition, the sliding door system comprises a compact unit comprising a frame of profile bars preferably detachably connected to each other, on which frame the linear guides are arranged. The guide profile is mounted on a guide rod (9a, 9b) via a heavy-duty recirculating ball bearing, roller or plain bearing, which components together define one of the two mutually parallel linear guides, wherein the two C- / U- / V- / L-shaped guide profiles are aligned the same.

Advantageously, the two linear guides are identical and designed either as a rail-roller system, rail sliding system or as Kugelumflauf rail system.

It is essential according to claim 7, that the C- / U-N- / L-shaped guide profile is mounted on a guide rod via a heavy-duty recirculating ball bearing or roller or sliding bearing.

The advantage of this double linear guide with C- / U- / V- / L-shaped guide profile for the sliding sash is that now the entire sliding door system is much more stable in particular against loads in the depth direction (passage direction) is executed and thus a longer life of the sliding door system can be achieved, and a risk of injury can be reliably excluded by passing through the sliding door people. Another significant advantage is that a modular compact unit at the manufacturing site completely (or at least without door) can be mounted and adjusted by this double linear guide of the sliding leaf for each side of the door and thereby the installation costs can be significantly reduced. The required test runs can therefore take place almost completely at the factory and all important parameters can be set before delivery by qualified personnel. The assembly at the installation site can then be carried out by auxiliary personnel, who do not need to know more about the function of the sliding door system according to the invention.

Important in the sliding door system according to the invention is that the door wing is supported inside the passage opening neither on the ground, nor on the ceiling or on the lintel when he is driven into the passage opening or is in the closed position. However, a support and / or sealing in the closed position on the opposite on-site vertical support if necessary. About a door frame is possible in other embodiments, as well as a support and / or seal on an opposite corresponding door, if available.

The sliding leaf is in this case arranged on a cross member, which cross member slides slidably via linear guides, if necessary. Driven by a toothed belt, which is operated by a motor (optionally with gear). The optional motor with optional countershaft, and associated power and control unit, as well as the cross member for the sliding sash are arranged on a compact unit, so that only the door itself is at least in the closed position outside the compact unit. This compact unit includes a frame of preferably releasably connected profile bars, for example, in cross-section with an X-shaped profile, so that this frame can be easily, quickly and inexpensively and can be easily, quickly and inexpensively equipped with the components described above for compact unit , The profile bars are in this case preferably made of a light metal, in particular Made of aluminum and its alloys. A compact unit made of folded steel or aluminum sheet is also being considered.

The motor can be pneumatic or electric in asynchronous DC or linear motor technology. Alternatively, the motor for the door can also be omitted and the door can also be operated manually. If there is a motor and it fails, e.g. due to power failure, the door can be opened or closed by little manual force, resulting in improved safety in an emergency. Other emergency opening systems, such as Elastic, rope emergency opening or battery module can also be used and are state of the art.

In the open state, the door leaf may extend beyond the contour of the compact unit on one side (eg upward), but may also protrude beyond the outer dimensions of the compact unit on two, three or all four sides. Thus, the compact unit can be manufactured with relatively small external dimensions and requires only a small amount of space on or within an on-site wall, floor or ceiling. Thus, the on-site costs for surface mounting or installation of the compact unit are also lower than in the prior art. Also, so that only a single compact unit for different door heights can be used, which brings lower manufacturing and storage and repair costs. The compact unit can be arranged arbitrarily on a building due to their small external dimensions, either on / in a vertical wall, on / in a ceiling or a lintel or on / in a horizontal floor, so that thus the direction of movement of the door leaf either horizontally or vertically and therefore can be arbitrary.

In a preferred embodiment of the present invention, the two linear guides are arranged in the region of two opposite outer edges of the frame of the compact unit. In another embodiment, however, the two linear guides can also lie closer to one another and are therefore arranged slightly away from the outer edges on the frame of the compact unit. In extreme cases, the two linear guides could only have a very small distance from each other or even directly adjoin one another, it being only important that tilting forces can be absorbed in the depth direction (passage direction), but also in the width direction (sliding direction).

The two linear guides are advantageously designed identically and provided either as a rail-roller system, rail-sliding system or as a recirculating ball rail system, the recirculating ball bearing can accommodate a high load and also complete a large number of opening / closing cycles can, so the life is increased.

The guide rails of the recirculating ball variant are preferably C- or U-shaped, with the opening of the "C" or the "U" facing away from the door itself, so that the cross member for the door leaf on the rear base leg of the "C" and the "U" rests and is fixed there. It is also important that the two side legs of the C or U-shaped guide rail at least partially surround the fixed rollers or balls of the recirculating ball bearing, so that thus a trigger safety is created transversely to the sliding direction of the sliding door. In other embodiments of the present invention, the guide rails are V- or L-shaped, so there is no restriction on a C- or U-shaped guide rail.

In another embodiment of the present invention, the door leaf can also be designed as a two-part or multi-part, telescoping door leaf, and the rail system can be designed as a partial, full or even over-extension.

The structure may be provided in a manner known per se with and without attached in the sliding range sealing profiles, used in automatic design or in sealing profiles brush or rubber seals, these sealing profiles also be prepared for receiving skylights or wall integrations and connections can, as known in the art.

The door itself may consist of a single glass, or of a multiple insulating glass with or without frame profiles including optional sealing profiles that may be visible or invisible integrated. Also, the door can be made of steel and / or wood and also as a fire door for use as a space and / or fire section door or lock.

In the area of the door revealing conventional sensors for the control of the door on the compact unit may be provided, which can be pre-assembled at the manufacturer.

In the following the invention will be explained in more detail with reference to drawings showing only one embodiment. Here are from the drawings and their description further features essential to the invention and advantages of the invention.

Figures 1 and 2 show the sliding door system according to the invention in the open position ( Fig. 1 ) and in the closed position of the sliding door ( Fig.2 ).

The compact door 1 includes a compact unit 1 and a sliding sash 2. The compact unit 1 is formed by a frame 3 consisting of four profile bars 4a - 4d which are detachably connected to each other on the corner or front side, whereby for reasons of reinforcement or to accommodate the Motor unit center additionally a longer profile bar 4e is introduced, parallel to the longer profile bars 4a, 4b and perpendicular and centered on the shorter profile bars 4c and 4d. The shorter profile bars 4c, 4d are here designed as a double X-profile resting on each other in the depth direction (passage direction) 14, whereas the longer profile bars 4a, 4b, 4e have a simple X-shape.

On the profile bars 4, the other components of the compact unit 1 are now mounted, namely a motor 5 with power and control unit, and a driven by this motor 5 toothed belt 7, which runs over deflection 6a, 6b and tension rollers 6c.

On the shorter profile bars 4a and 4b are each a linear guide 8 is provided, each consisting of a guide rod 9 and a respective C- or U-shaped guide profile 10, wherein the two guide rods 9a, 9b, and the two corresponding thereto two guide profiles 10a, 10b of course extend in the sliding direction 11 of the sliding door 2.

On the two guide profiles 10a and 10b, a transverse support 12 is arranged transversely thereto and parallel to the sliding direction 11 of the sliding door 2, on which a fixed driver 13 is located, which is engageable with the toothed belt 7 or constantly. By the driver 13, the cross member 12 can be moved by means of the motor 5 and the toothed belt 7 in the sliding direction 11, ie in the closing direction 11 a, and in the opening direction 11 b. As ever one of the two deflection rollers 6 a and 6 b are positioned approximately at the same distance from the guide section 10 a on the longer profile bars 4 a, 4 b, the intervening section 7 a of the toothed belt 7 is approximately parallel to the sliding direction 11 and thus an effective force is transmitted from the motor 5 via the toothed belt 7 ensured on the cross member 12 and thus on the sliding wing thereon. 2

In FIG. 3 It can be seen that the two C- / U-shaped guide profiles 10a, 10b each have a base leg 16, on the vertical end side of each side legs 17, 18 is arranged. In this embodiment, the C- / U-shaped guide profiles 10a, 10b are arranged standing, so that the base legs 16a, 16b transverse to the sliding direction 11 and the side legs 17a, 17b, 18a, 18b in the sliding direction 11 and thus carry the entire weight of the Door leaf 2, the two lower side legs 18a and 18b of the two C- / U-shaped guide profiles 10a, 10b together and divide them in the ideal case about half. A horizontal embodiment of the guide profiles 10a, 10b can also be used to optimize the size of the compact unit 1.

Important for the present invention is that a double guide system 8 of the door leaf 2 is present, with two parallel, spaced-apart linear guides 8a, 8b, each having a C- or U-shaped guide profile 10a, 10b, the legs together the entire load of Record the door leaf. Transversely to the sliding direction of the door leaf 2 on the guide profiles 10a, 10b is operable by hand or motor 5 with toothed belt 7 cross member 12 is fixed, on which the door leaf 2 is received. In particular, between this guide profile 10a, 10b and each guide rod 9a, 9b a recirculating ball bearing, roller or sliding bearing (not shown) is present, which has a high load capacity and thus a long life.
