DESCRIPTION

Sliding door system

The invention relates to a sliding door system on at least one side of a passage opening of a construction site, which at least contains a sliding door leaf, given chaos, telescopic once or several times, as well as optionally at least one sliding door drive, according to the preamble of claim 1 of the patent.

Such sliding door systems are known in numerous ways from the prior art.

Thus, for example, document DE 19819558 A1 already publishes a lateral drive for a sliding door, as well as guide rails in the form of a U / O above the entire area of the door, also above the passage opening .

Document DE 4430941 A1 publishes a magnetic suspension guide of a sliding door, which is relatively expensive.

Document DE 2306206 A publishes a "cantilever" articulation sheet in the door opening, but not a sliding door leaf.

Document DE 1954791 U publishes a "cantilever" sliding grid door in the opening of the door according to the preamble of the claims of patent 1 and 7, respectively, such as document DE 10321547 A1 and document EP 1477631 A2 parallel and identical to it.

The last two publications mentioned publish an automatic sliding door with at least one horizontally movable door leaf by means of a drive, in which the drive is arranged laterally with respect to the passage opening defined by the closed door leaf and in which the door leaf is projected in its closed position "in free suspension" in the passage opening. The door leaf can be supported and guided in an advantageous embodiment on the upper lintel or on the cover by means of a U-shaped guide laterally in the depth direction (passage direction). It is not indicated in detail what exactly is meant here by a "free-hanging" door leaf within the passage opening. But no support is provided at the bottom and / or in the suspension on the lintel or on the door leaf cover within the passage opening.

In all the aforementioned embodiments of the state of the art it is a disadvantage that these either imply a high level of assembly work at the place of assembly of the door or, instead, as in a special embodiment of the document DE 10321547 A1 or of document EP 1477631 A2 without U-shaped upper lateral guide, has relatively low stability during the closing process and in the closed state of the door leaf or the moment of tilting that appears under from the door leaf mounted laterally to the guide system, it cannot be absorbed without counter bearing. Also the force of the weight, the driving moments and the tilting moments are absorbed by a single guide.

EP-A-1 743 824 publishes a sliding door construction for platforms, comprising two stationary lateral fixed parts as well as two sliding doors, which are closed synchronously and in the opposite direction. The sliding doors have a surrounding frame and are configured in cantilever, that is, between the bottom and the bottom edge of the door remains a small slit of up to 30 mm. For the door two suspensions are provided on the side of the track, namely an upper suspension in the area of the upper edge of the sliding doors and a lower suspension in the lower area of the sliding doors. The lower suspension has a stationary guide element, which is arranged in the fixed part. A guide rail configured as a U-profile is attached to the respective door, which together with the guide element forms a roller bearing or ball bearings. In this case, the guide rail projects backwards beyond the actual width of the door.

An electric motor is provided for the door drive, which has a helical gear, which drives a toothed belt drive roller. In gear with the toothed belt drive roller is a toothed belt, which is deflected on two deflection rollers symmetrically arranged above the deflection rollers of the toothed belt. The ends of the toothed belt are fixed in the guide rail.

The upper suspension has an upper door profile, which is part of the surrounding door frame. In this upper profile of the door a profiled guide rail is fixed, which extends at least over the width of the sliding door. As a fixing element, a guide profile 15 is fixed in the upper area of the fixing element. But now the profiled guide rail does not fit directly into the guide profile but the upper guide is configured as a telescopic guide, in which A telescopic profile is arranged mobile between these two elements. The telescopic profile is movable both with respect to the profiled guide rail and also

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 approximately half the height of the sliding doors. Stabilize the sliding doors only in the horizontal direction. The support in the vertical direction is fully assumed by the lower guide.

Document DE-U-201 02 740 publishes a sliding door to close a wall opening between spaces in the interior extension, which comprises two support rails displaced from one another in the longitudinal direction, arranged up and down, which guide, respectively, a translation mechanism, for example rollers or a carriage. In this case, one support rail is located at the top in the frame lintel and the other support rail is located next to the frame in the direction of the opening, extending over a guard strip. The rollers or the carriage are fixed on the surface of the door side of the door leaf in cantilever plates. For the stabilization of the gait of the door, on the bottom of the base there is a free bottom guide for covered play. A feature of the D2 door system is that the door leaf, when the wall opening is closed, is fully supported by the upper support rail and when the wall opening is open, it is supported by the lower wall of support.

US Patent No. 5,395,165 publishes a furniture door for a television cabinet, which pivots first for opening and then pushes back along two parallel guide rails, so that it is supported adjacent to Wall.

Therefore, the purpose of the present invention is to develop a sliding door system according to the state of the art mentioned at the beginning, in such a way that lower costs are produced with respect to the assembly works in the place of assembly of the sliding door system, and in such a way that additionally the door leaf has essentially higher stability during the closing process and in the closed state and with this the sliding door system has a useful life higher.

The solution of these tasks is achieved by means of the characteristics of the independent claim 1 of the patent.

According to claim 1 of the patent, it is essential that one arm of the C / U / V / L shaped guide profile of the other linear guide simultaneously supports the force of the weight of the sliding door leaf and of In this way the force of the weight, the driving moments and the tilting moments are distributed on two guides. In addition, the sliding guide system has a compactness that contains a frame formed by profiled bars, preferably detachably connected to each other, in which frame the linear guides are arranged. The guide profile is housed on a surrounding housing of high load bearing balls, roller housing or sliding housing on a guide bar (9a, 9b), whose components jointly define one of the two linear guides spaced parallel to each other. , in which the two guide profiles in the form of C / U / V / L are aligned equally.

Advantageously, the two linear guides are identical and are either configured as a lane roller system, lane sliding system or as a ball lane system.

According to claim 7, it is essential that the C- / UN- / L-shaped guide profile is housed over a ball bearing housing with high load capacity, roller housing or sliding housing on a guide bar .

An advantage of this double linear guide with C / U / V / L-shaped guide profile for the sliding leaf is that now the entire sliding door system is made essentially more stable, in particular in the face of loads in the direction of the depth (passage direction) and with this a longer lifespan of the sliding door system can be achieved, as well as a risk of injury to persons passing through the door can be reliably excluded slide. Another essential advantage is that through this double linear guide of the sliding leaf for each side of the door a modular compact unit can be mounted and adjusted completely at the manufacturing site (or at least without door leaves) and This way you can essentially reduce assembly costs. Therefore, the necessary test cycles can take place almost completely already in the production factory and all important parameters can be adjusted already before delivery by technical personnel. Assembly at the installation site can then be carried out by auxiliary personnel, who do not have to have more exact knowledge about the function of the sliding door system according to the invention.

In the sliding door system according to the invention it is important that the door leaf does not rest inside the passage opening or at the bottom, or on the cover or on the doorpost, when it is moved to the passage opening or is in the closed position. A support and / or seal in the closed position on the opposite vertical support on the side of the construction, if necessary, on a door frame is not possible, however, in other embodiments, as well as a support and / or shutter on a door leaf

corresponding opposite, if present.

The slide sheet is arranged in this case on a transverse support, whose transverse support slides in a sliding manner on linear guides, if necessary driven on a toothed belt, which is driven by a motor (optionally with gear). The optional motor with optional reducer, as well as the respective power and control unit, as well as the transverse support for the sliding leaf are arranged on a compact unit, so that only the door leaf itself is in the position closed out of the compact unit. This compact unit contains a profiled bar frame preferably connected detachably to each other, for example in the cross section with an X-shaped profile, so that this frame can be formed in a simple, fast and economical manner and is You can equip with the components described above to form the compact unit in a simple, fast and economical way. The profiled bars are manufactured in this case with preference of a light metal, in particular aluminum and its alloys. In the same way it is conceivable a compact unit of steel or of edged aluminum sheet.

The motor can be made pneumatically or electrically, in asynchronous DC motor technology

or in linear motor technology. Alternatively, the motor for the door leaf can also be suppressed

or the door leaf can also be operated manually. If a motor is present and it fails, for example due to the failure of the current, then the door leaf can be opened or closed by means of reduced manual force, which leads to improved safety in case of emergency. In the same way other emergency opening systems such as elastic cord, emergency cable opening or battery module can be used and are state of the art.

The door leaf can be extended in the open state on one side (for example, upwards) beyond the contour of the compact unit, but it can also be projected on two, three or all four sides beyond the average outside of the compact unit. In this way, the compact unit can be manufactured with relatively small exterior measurements and only a reduced construction space is needed on or within the side wall, the bottom or the roof of the construction. In this way, the costs on the construction side for recessed mounting or assembly of the compact unit are lower than in the prior art. In this way, only a single compact unit for different door heights can be used, which means lower manufacturing and storage costs as well as repair costs. The compact unit can be arranged by virtue of its exterior measures discretionally reduced in a construction, either together / on a vertical wall, together / on a cover or on a doorpost or together / on a horizontal bottom, so that with this the direction the movement of the door leaf can be either horizontal or vertical and, therefore, can be discretionary.

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

The two linear guides are advantageously configured identical and are provided either as a lane roller system, lane sliding system or, instead, as a ball movement slider system, the ball circulation guide being able to absorb a ball high support load and also being able to absorb a high number of opening / closing cycles, so that the lifespan is increased.

The guide rails of the ball circulation variant are preferably configured in a C-shape or a U-shape, with the opening of the "C" or the "U" pointing out of the door leaf itself, so that the transverse support for the door leaf rests on the rear base arm of the "C" or "U" and is fixed there. It is also important that the two lateral arms of the C-shaped or U-shaped guide rail at least partially surround the fixed rollers or the balls of the ball-circulation housing, so that an extraction safety is created transversely to the sliding direction of the sliding door. In other embodiments of the present invention, the guide rails are V-shaped or L-shaped, so that there is no limitation on a C-shaped or U-shaped guide rail.

The door leaf can be configured in another embodiment of the present invention also as a telescopic door leaf of two or more parts, as well as the rail system can be configured as a partial, total or even telescopic tube as an excessive telescopic tube .

The structure can be provided in a manner known per se with and without sealing profiles placed in the sliding area, in the form of an automatic embodiment or with sealing joints of brushes or rubber

inserted in sealing profiles, these sealing profiles can also be prepared for the reception of upper light glazing or wall integrations and connections, as is known from the prior art.

The door leaf itself can be constituted of a single glass or, instead, of a multiple insulating glass with or without frame profiles, including optional sealing profiles, which can be visibly or invisibly integrated. The door leaf can also be made of steel and / or wood and also as a fire door leaf for use as a door or a space shutter and / or firewall.

Conventional sensors for the control of the door in the compact unit, which can be pre-assembled by the manufacturer, can be provided in the intrados area of the door.

The invention is explained in detail below with the help of drawings that represent only one embodiment. In this case, other essential characteristics and advantages of the invention are taught from the drawings and their description. In this case:

Figure 1 shows a front view of the sliding door system according to the invention with the sliding leaf in the open position.

Figure 2 shows a front view of the sliding door system according to the invention with the sliding leaf in the closed position.

Figure 3 shows a side view of the sliding door system according to the invention in the sliding direction of the sliding leaf.

Figure 4 shows a top plan view on figure 1.

Figure 5 shows a top plan view on figure 2.

Figures 1 and 2 show the sliding door system according to the invention in the open position (figure 1) and in the closed position of the sliding door (figure 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 made up of four profiled bars 4a-4d arranged in a rectangular manner, which are joined together removable from each other on the side of the corner or on the front side, so that for reasons of rigidity or for the reception of the motor unit in the center, a longer profiled bar 4e is also placed parallel to the bars 4a, 4b longer and vertical profiles and centered on the shortest profiled bars 4c and 4d. The shorter profiled bars 4c, 4d are made here as a double X profile superimposed in the depth direction (pitch direction) 14, however the longer profiled bars 4a, 4b, 4e have a simple X-shape.

On the profiled bars 4 the other components of the compact unit 1 are now placed, namely a motor 5 with power regulation unit and control unit as well as an entada belt 7 driven by this motor 5, which runs on rollers deviation 6a, 6b and tension rollers 6c.

On the shorter profiled bars 4a and 4b there is provided, respectively, a linear guide 8, which is constituted, respectively, by a guide bar 9 and a respective C-shaped or U-shaped guide profile 10, so that the two guide bars 9a, 9b as well as the two guide profiles 10a, 10b corresponding thereto naturally extend in the sliding direction 11 of the sliding door 2.

On the two guide profiles 10a and 10b a transverse support 12 is disposed transversely thereto and parallel to the sliding direction 11 of the sliding door 2, in which there is a stationary fixed drive element 13, which can be carried to engage and is constantly engaged with the toothed belt 7. Through the drive element 13 the transverse support 12 can be moved by means of the motor 5 and the toothed belt 7 in the direction of the slide 11, that is, in the closing direction 11a, as well as in the opening direction 11b. Since each of the two deflection rollers 6a and 6b are positioned approximately the same distance from the guide profile 10a on the longer profiled bars 4a, 4b, the section 7a of the belt entails 7 which is in the middle extends approximately parallel to the direction of slider 11 and, therefore, an effective introduction of the force from the motor 5 through the toothed belt 7 on the transverse support 12 and with it on the slider sheet 2 above is ensured of the same.

In Fig. 3 it can be recognized that the two guide profiles 10a, 10b in the form of a U / O have, respectively, a base arm 16, on which a side arm 17 is arranged vertically, respectively, 18. In this embodiment, the guide profiles 10a, 10b in the form of a U / U are arranged vertically, so that the base arm 16a, 16b extends transversely to the sliding direction 11 and the side arms 17a, 17b, 18a, 18b extend in the direction of slide 11 and thus concentrate

all the force of the weight of the door leaf 2 the two lower lateral arms 18a and 18b of the two guide profiles 10a, 10b in the form of a U / U and these are distributed in the ideal case approximately in the middle. An extended embodiment of the two guide profiles 10a, 10b can be used in the same way for the optimization of the construction size of the compact unit 1.

For the present invention it is important that a double guide system 8 of the door leaf 2 is present, with two parallel linear guides 8a, 8b spaced apart from each other, which respectively have a guide profile 10a, 10b in C-shaped or U-shaped, whose arms together absorb the entire load of the door leaf. Transversally to the sliding direction of the door leaf 2 on the guide profiles 10a, 10b a transverse support 12 is fixed which can be operated by hand or with motor 5 with toothed belt 7, on which the leaf is housed of the door 2. In particular, between this guide profile 10a, 10b and a respective guide bar 9a, 9b there is a ball circulation housing, a roller housing or a sliding housing (not shown), which has a high load capacity and therefore a long service life.
