Description

The invention relates to a sliding-door system for placing on at least one side of an opening of a construction, containing at least one sliding-door leaf of optionally single or multiple telescopic design and optionally at least one sliding-door drive, according to the preamble of Patent Claim 1.

Sliding-door systems of this type are widely known from the prior art.

For example, DE 19819558 A1 already discloses a lateral drive for a sliding door as well as C-shaped/U-shaped guide rails above the entire door region, also above the opening. DE 4430941 A1 discloses a magnetic-levitation guide for a sliding door, which is comparatively costly. DE 2306206 A discloses a pivoted leaf which is “self-supporting” in the door opening, but not a sliding-door leaf. DE 1954791 U discloses sliding-grating gate which is “self-supporting” in the door opening, according to the preamble of Patent Claim 1 or 7 respectively, likewise DE 10321547 A1 and EP 1477631 A2 which is parallel and identical therewith.

The two last-mentioned publications disclose an automatic sliding door having at least one door leaf which is horizontally displaceable by means of a drive, wherein the drive is disposed so as to be lateral in relation to the opening which is defined by the closed door leaf, and wherein the door leaf in its closed position protrudes into the opening in a “self-supporting” manner. In one advantageous embodiment the door leaf in the direction of depth (direction of passage) can be laterally supported and guided on the upper lintel or on the ceiling, respectively, by a U-shaped guide. There is no more detailed discussion relating to the more exact meaning of a door leaf which is “self-supporting” within the opening. However, no support of the door leaf within the opening on the floor and/or suspension from the lintel or the ceiling is provided.

It is a disadvantage of all previously mentioned embodiments of the prior art that they either necessitate a large amount of assembly works at the installation site of the door, or as is the case in a special embodiment of DE 10321547 A1 or EP 1477631 A2, respectively, without an upper lateral U-shaped guide, have comparatively low stability during the closing operation and in the closed state of the door leaf, or without a counterbearing cannot absorb the tilting effect which arises on account of the door leaf which is mounted so as to be lateral to the guide system. Moreover, the weight force, the drive torque and the tilting effect are absorbed by only one guide. EP-A-1 743 824 discloses a sliding-door construction for rail platforms, comprising two lateral stationary fixed parts as well as two sliding doors which close in a synchronous and reciprocal manner. The sliding doors have an encircling frame and are configured in a self-supporting manner, that is to say that a small gap of up to 30 mm remains between the floor and the lower edge of the door. Two suspensions are provided for the door 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 lowermost region of the sliding doors. The lower suspension disposes of a stationary guide element which is disposed on the fixed part. A guide rail which is configured as a U-profile and which together with the guide element forms a roller bearing or ball bearing is fastened to the respective door. Here, the guide rail protrudes rearward beyond the actual width of the door.

An electric motor, which is via a worm gear which drives a toothed-belt drive pulley, is provided for driving the doors. A toothed belt which is deflected via two deflection rollers which are symmetrically disposed above the toothed-belt deflection rollers meshes with the toothed-belt drive pulley. The ends of the toothed belt are fastened to the guide rail.

The upper suspension disposes of an upper door profile which forms part of the encircling door frame. A guide-profile rail which disposes of at least the width of the sliding door is fastened to said upper door profile. A guiding profile 15 is fastened as a fixed element in the upper region of the fixed element. Said guiding profile, however, does not directly engage in the guide-profile rail, but the upper guide is configured as a telescopic guide in which a telescopic profile is movably disposed between these two elements. The telescopic profile is displaceable both in relation to the guide-profile rail and also the guiding profile. The use of the telescopic profile enables a particularly large expanse of the guide.

According to another embodiment, the upper guide is disposed at about half the height of the sliding doors. Said upper guide stabilizes the sliding doors only in the horizontal direction. Support in the vertical direction is completely assumed by the lower guide. DE-U-201 02 740 discloses a sliding door for closing a wall opening between rooms in interior architecture, comprising two support rails which are disposed at the top and the bottom so as to be mutually offset in the longitudinal direction and which in each case guide one running gear, for example rollers or a carriage. Here, one support rail is placed at the top in the frame lintel, and the other support rail is placed beside the frame, above a skirting board, so as to be direction-ally guiding in the opening direction. The rollers or the carriage are fastened to the wall-side face of the door leaf, on adjustable cantilevered plates. In order to stabilize the movement of the door, a concealed floor guide which is free of clearance is provided on the floor. It is a characteristic of the sliding-door system of D2 that the door leaf is entirely supported by the upper support rail when the wall opening is closed and entirely supported by the lower support rail when the wall opening is opened. US Patent No. 5,395,165 discloses a furniture door for a television stand, which for opening is first pivoted and then pushed back along two parallel guide rails in order for said door to come to lie adjacent to the wall.

It is thus an object of the present invention to refine a sliding-door system according to the prior art mentioned at the outset in such a manner that lower costs in relation to the assembly works at the installation site of the sliding-door system arise, and that the door leaf has considerably enhanced stability during the closing operation and in the closed state and the sliding-door system thus has a longer service life.

These objects are achieved by the features of the independent Patent Claim 1.

It is significant according to Patent Claim 1 that a leg of the C-shaped, U-shaped, V-shaped, L-shaped guiding profile of the other linear guide collaboratively bears the weight force of the sliding-door leaf, and the weight force, the drive torque, and the tilting effect are thus distributed across two guides. Moreover, the sliding-door system comprises a compact unit containing a frame made of profile rods preferably releasably connected with one another, on which the linear guides are disposed. The guiding profile is positioned over a heavy-duty recirculating ball bearing, a roller bearing or a sliding bearing on a guiding rod (9a, 9b), which components define together one of the two linear guides spaced parallel to each other, wherein both C-shaped, U-shaped, V-shaped, L-shaped guiding profiles are oriented the same way.

Advantageously, the two linear guides are identical and are configured either as a rail-and-roller system, a rail sliding system, or as a recirculating ball bearings rail system.

It is significant according to Patent Claim 7 that the C-shaped, U-shaped, N-shaped, L-shaped guiding profile is supported by way of a heavy-duty recirculating ball bearing or a roller bearing or sliding bearing, respectively, on a guiding rod.

An advantage of this double-linear guide having a C-shaped, U-shaped, V-shaped, L-shaped guiding profile for the sliding leaf is that now the entire sliding-door system is implemented in a substantially more stable manner, in particular in relation to stresses in the direction of depth (direction of passage), and a longer service life of the sliding-door system can thus be achieved, and risk of injury to persons passing through the sliding door can be reliably precluded. It is a further significant advantage that on account of this double-linear guide of the sliding leaf, a modular compact unit can be assembled and adjusted completely (or at least without door leaf) for each side of the door at the manufacturing site and, on account thereof, the assembly costs can be significantly reduced. The necessary test runs can thus almost all take place already at the factory, and all important parameters can be set by expert personnel already prior to delivery. On account thereof, assembly at the installation site can be performed by auxiliary personnel who do not have to have any more detailed knowledge pertaining to the functioning of the sliding-door system according to the invention.

It is important in the case of the sliding-door system according to the invention that the door leaf within the opening is neither supported on the floor nor on the ceiling nor the door lintel, respectively, when being moved into the opening or being in the closed position. However, supporting and/or sealing in the closed position is possible in other embodiments on the opposite vertical support on the construction-side, optionally by way of a door casing, as is supporting and/or sealing on an opposite corresponding door leaf, if available.

Here, the sliding leaf is placed on a transverse support which is guided so as to be displaceable over linear guides, optionally driven by a toothed belt which is operated by a motor (optionally having a gearbox). The optional motor having an optional transmission, and the power and control unit belonging thereto, as well as the transverse support for the sliding leaf, are placed on a compact unit, such that only the door leaf itself, at least in the closed position, is located outside the compact unit. This compact unit contains a frame made of profile rods preferably re-leasably connected with one another, for example having an X-shaped profile in the cross section, such that this frame can be erected in a simple, rapid, and cost-effective manner, and can be equipped with the components described above in a simple, rapid, and cost-effective manner in order to form the compact unit. The profile rods here are preferably made of a light alloy, in particular aluminium and alloys thereof. A compact unit made of edge-folded steel or aluminium sheets is likewise conceivable.

The motor may be implemented so as to be pneumatic or electric, in either asynchronous DC technology or linear-motor technology. Alternatively, the motor for the door leaf may be deleted and the door leaf be operated manually. Where a motor is available and said motor is out of operation, for example on account of loss of power, the door leaf may be opened or closed by hand with little effort, leading to improved safety in an emergency. Further emergency opening systems, for example a rubber pull, a rope-type emergency opener, or a battery module may likewise be employed and are in the prior art.

In the open state the door leaf may on one side (for example towards the top) project beyond the contour of the compact unit, but may also project beyond the external dimensions of the compact unit on two, three, or all four sides. The compact unit can thus be manufactured so as to have comparatively small external dimensions and requires an only small installation space on or within a construction-side wall, floor, or ceiling. On account thereof, the construction-side costs for surface-mounting or installing the compact unit are also lower than in the prior art. On account thereof, only a single compact unit may also be employed for various door heights, resulting in lower manufacturing, storage and repair costs. On account of its small external dimensions, the compact unit may be arbitrarily disposed on a building, either on/in a vertical wall, on/in a ceiling or a door lintel, or on/in a horizontal floor, such that, on account thereof, the direction of movement of the door leaf may either be horizontal or vertical and, therefore, arbitrary.

In one preferred embodiment of the present invention, the two linear guides are placed in the region of two mutually opposite outer edges of the frame of the compact unit. In another embodiment the two linear guides may also lie so as to be closer together and are thus placed on the frame of the compact unit so as to be somewhat distant from the outer edges. In an extreme case, the two linear guides may be only very slightly spaced apart or even be directly adjacent to one another, wherein it is only important for tilting forces in the direction of depth (direction of passage) and also in the direction of width (sliding direction) to be able to be absorbed.

Advantageously, the two linear guides are configured so as to be identical and are provided as either a rail-and-roller system, a rail sliding system, or as a recirculating ball bearings rail system, wherein the recirculating ball bearings guide can absorb a high supported load and can also perform a high number of opening-and-closing cycles, thus increasing the service life.

The guiding rails of the recirculating ball bearings variant are preferably C-shaped or U-shaped, wherein the opening of the “C” or of the “U”, respectively, faces away from the door leaf itself, such that the transverse support for the door leaf bears on the rearward base leg of the “C” or of the “U”, respectively, and is fastened there. It is also important that the two lateral legs of the C-shaped or U-shaped guiding rail at least partially encompass the fixed rollers or ball bearings, respectively, of the recirculating ball bearing, such that security in relation to removal in the transverse direction to the sliding direction of the sliding door is achieved therewith. In other embodiments of the present invention the guiding rails are configured so as to be V-shaped or L-shaped, so that there is no limitation in relation to a C-shaped or U-shaped guiding rail.

In another embodiment of the present invention the door leaf may also be configured so as to be a telescopic door leaf having two or multiple parts, and the rail system may be designed so as to be a partial, complete, or even a super pull-out.

The construction may be provided in a fashion known per se with or without sealing profiles which are attached in the sliding region, in an automatic implementation, or with brush-type or rubber seals, respectively, which are inserted into sealing profiles, wherein these sealing profiles may also be prepared for accommodating indirect-window glazing or wall integrations and connections, respectively, as are known from the prior art.

The door leaf itself may be composed of single glazing, or else of a multiple insulation glazing with or without frame profiles and optional sealing profiles which may be integrated so as to be visible or invisible. The door leaf may also be made of steel and/or wood, and also be suitable as a fire-safety door leaf for use as a room door and/or a fire zone door or lock, respectively.

Conventional sensors for controlling the door via the compact unit may be provided in the region of the door reveal and may be pre-assembled at the manufacturer’s premises.

The invention will be described in more detail herebelow by means of drawings which illustrate merely one exemplary embodiment. Further features and advantages which are relevant to the invention can be derived from the drawings and the description thereof. In the drawings:

Fig. 2 shows a front view of the sliding-door system according to the invention, with the sliding leaf in the closed position;

Fig. 3 shows a side view of the sliding-door system according to the invention, in the sliding direction of the sliding leaf;

Fig. 4 shows a plan view of Fig. 1;

Fig. 5 shows a plan view of Fig. 2.

Figs. 1 and 2 show the sliding-door system according to the invention, in the opened position (Fig. 1) and in the closed position of the sliding door (Fig. 2).

The sliding-door system contains a compact unit 1 as well as a sliding leaf 2. The compact unit 1 is formed by a frame 3 which is composed of four profile rods 4a -4d which are disposed in a rectangular manner and which at the corners or the end faces, respectively, are releasably connected to one another, wherein for reasons of rigidity or for receiving the motor unit, respectively, a longer profile rod 4e is additionally incorporated in a centric manner, so as to be parallel with the longer profile rods 4a, 4b and plumb-vertical and centric on the shorter profile rods 4c and 4d. Here, the shorter profile rods 4c, 4d are implemented so as to lie on top of one another in the direction of depth 14 (direction of passage) as a dou-ble-X profile, whereas the longer profile rods 4a, 4b, 4e have a simple X-shape.

The further components of the compact unit 1 are now attached to the profile rods 4, namely a motor 5 having a power and control unit, and a toothed belt 7 which is driven by this motor 5 and which runs via deflection rollers 6a, 6b, and tensioning rollers 6c.

Each one linear guide 8 which is composed of each one guiding rod 9 and each one C-shaped or U-shaped guiding profile 10 is provided on the shorter profile rods 4a and 4b, wherein the two guiding rods 9a, 9b, as well as the two guiding profiles 10a, 10b which correspond thereto, of course extend in the sliding direction 11 of the sliding door 2. A transverse support 12, having a fixed driver pin 13 disposed thereon which can be brought to engage or is permanently engaged in the toothed belt 7, is disposed on the two guiding profiles 10a and 10b so as to be transverse thereto and parallel with the sliding direction 11 of the sliding door 2. By way of the driver pin 13 the transverse support 12 can be displaced by means of the motor 5 and of the toothed belt 7 in the sliding direction 11, that is to say in the closing direction 11a, as well as the opening direction 11b. Since one each of the two deflection rollers 6a and 6b are positioned at an approximately equal spacing from the guiding profile 10a on the longer profile rods 4a, 4b, the portion 7a of the toothed belt 7 which is located therebetween runs approximately parallel with the sliding direction 11, thus ensuring an effective introduction of force from the motor 5 via the toothed belt 7 onto the transverse support 12 and thus onto the sliding leaf 2 located thereon.

It can be seen in Fig. 3 that the two C-shaped/U-shaped guiding profiles 10a, 10b have in each case one base leg 16 on which in each case one lateral leg 17, 18 is disposed in a plumb-vertical manner. In this embodiment the C-shaped/U-shaped guiding profiles 10a, 10b are disposed so as to be upright, such that the base leg 16a, 16b runs transversely to the sliding direction 11 and the lateral legs 17a, 17b, 18a, 18b run in the sliding direction 11, on account of which the two lower lateral legs 18a and 18b of the two C-shaped/U-shaped guiding profiles 10a, 10b collaboratively support the entire weight force of the door leaf 2 and in the ideal case approximately equally split said force weight between them. A horizontal embodiment of the guiding profiles 10a, 10b may also be employed in order to optimize the overall size of the compact unit 1.

It is important for the present invention that a double guiding system 8 of the door leaf 2 is available, having two parallel linear guides 8a, 8b which are spaced apart from one another and which in each case have one C-shaped or U-shaped guiding profile 10a, 10b, the legs of which collaboratively absorb the entire load of the door leaf. A transverse support 12, which is operatable by hand or by the motor 5 with toothed belt 7 and on which the door leaf 2 is accommodated, is fastened on the guiding profiles 10a, 10b, so as to be transverse to the sliding direction of the door leaf 2. In particular, between this guiding profile 10a, 10b and each one of the guiding rods 9a, 9b there is a recirculating ball bearing, a roller bearing, or a sliding bearing (not illustrated) which has a high resistance to stress and thus a long service life.
