SLIDING DOOR SYSTEM FOR INSTALLATION INTO A BUILDING WALL

Description

[0001] The present invention relates to a sliding door system for installation in a building wall.

[0002] A sliding door can comprise two opposing door leaves that are pivotally mounted on a horizontally movable door leaf support. When the door leaf support is moved, for example, by means of an electric drive, a pivoting mechanism can be used to pivot the door into corresponding door openings in a building wall. Such a sliding door can be referred to as a "wallpaper door." The opening and closing of the sliding door should be as quick as possible for safety and practical reasons. At the same time, it should be ensured that the forces generated are not excessive, with a view to ensuring the most durable and cost-effective construction possible, or for reasons of comfort. Aesthetic aspects can also play an important role.For example, the mechanism of the sliding door should not be visible from the outside when installed, but should still be easily accessible for repair and maintenance purposes.

[0003] Examples of such a sliding door are shown in AT 507 815 A1 ES 2 662 701 B1 and DE 101 63 061 A1.

[0004] There may therefore be a need for a sliding door system for installation in a building wall that allows a sliding door to be opened and closed quickly, manufactured cost-effectively, and / or easily maintained.

[0005] This need can be met by the subject matter of the independent claim. Advantageous embodiments are defined in the dependent claims and in the following description.

[0006] The invention relates to a sliding door system for installation in a building wall. The sliding door system comprises a first wall section with a first door opening and a second wall section with a second door opening. The first wall section and the second wall section are arranged opposite one another, so that the first door opening is opposite the second door opening and the first wall section is separated from the second wall section by a gap.The sliding door system further comprises a first door leaf for closing the first door opening, a second door leaf for closing the second door opening, a door leaf support which is displaceable along the intermediate space by means of a linear guide device and on which the first door leaf and the second door leaf are pivotally mounted by means of a pivoting mechanism, and a coupling device for converting a displacement movement of the door leaf support into a rotational movement for actuating the pivoting mechanism, so that the first door leaf and the second door leaf are pivoted relative to the door leaf support. For this purpose, the coupling device comprises a link component with a link depicting a desired relationship between the displacement movement and the rotational movement, and a control lever for coupling the link to the pivoting mechanism. The link component is mounted on the first wall part and / or the second wall part.

[0007] The first and second wall parts can be parts of a housing of the sliding door system, which is suitable for installation in the building wall, more precisely in a corresponding recess in the building wall. The guide component can be mounted on and / or in the housing via the first and / or second wall parts. For example, the first and / or second wall parts can form a side wall, a floor, and / or a ceiling of the housing, wherein the guide component can be mounted on the side wall, the floor, and / or the ceiling.

[0008] The term "door leaf" can be understood as a flat, for example plate-shaped element, which can also be referred to as a door panel.

[0009] The door leaf support can be understood, for example, as a single, movable support or a movable assembly of several individual supports, such as in the form of a support frame. When the sliding door system is installed, the door leaf support can be arranged at least partially in the space between the first and second wall sections. However, it is also possible for the door leaf support to be arranged at least partially above and / or below the space.

[0010] In addition, the sliding door system can include an electric drive for moving the door leaf support along the gap.

[0011] The linear guide device can comprise one or more guide rails into which the door leaf support can be slidably mounted, for example, via rollers and / or sliding elements. When the sliding door system is installed, the door leaf support can be displaced in a horizontal direction by means of the linear guide device.

[0012] The pivoting mechanism can, for example, be designed to pivot the first and second door leaves in opposite directions relative to the door leaf support. The respective pivoting movements of the first and second door leaves can be coordinated with one another by means of the pivoting mechanism, for example, in such a way that the two door openings are closed and / or opened again by the respective door leaves as simultaneously as possible.

[0013] The gate can be implemented, for example, in the form of a groove or a slot in the gate component. The gate can comprise a defined profile with one or more straight and / or curved gate sections. The control lever can, for example, have a guide pin at one of its ends, which is mounted in the gate and can be moved along the gate.

[0014] In other words, the first and second door leaves can be controlled in their pivoting movement by one and the same guide and one and the same control lever. The guide can be the only guide for controlling the pivoting movement of the first and second door leaves.

[0015] The guide component can be firmly connected to the first and / or second wall section, for example, screwed or clamped thereto. The guide component can be arranged partially or completely outside the door leaf support. For example, the guide component can be arranged in an area of the gap that is not visible from the outside, such as above the first and / or second door opening and / or above the first and / or second door leaf. The guide component can be mounted on an inner side of the first and / or second wall section facing the gap. However, other installation locations for the guide component are also possible.

[0016] It is possible for the link component to be mounted on the first and / or second wall part via an adjusting device, wherein the adjusting device enables readjustment of a horizontal and / or vertical position of the link component after its assembly.

[0017] By mounting the guide rail component outside the door leaf support in this way, the manufacturing costs of the sliding door system can be reduced compared to conventional solutions with a guide rail control integrated into the door leaf support. Furthermore, simply replacing the guide rail component allows the sliding door system to be easily adapted to different installation locations, independent of the door leaf support. A further advantage is that the guide rail component can be designed significantly larger and therefore more robust than if it were mounted on or in the door leaf support.

[0018] The geometry of the backdrop, in particular its longitudinal direction, may, for example, have been selected depending on at least one of the following parameters: Mass and dimensions of the door leaves, diameter of any guide pin for guiding the control lever in the guide, desired course of each movement curve of the door leaves, length of the control lever, angle between the control lever and any pivot levers via which the door leaves are mounted on the door leaf support.

[0019] Possible features and advantages of embodiments of the invention may be considered, among other things and without limiting the invention, to be based on ideas and findings described below.

[0020] According to one embodiment, the gate can comprise a straight first gate section, a straight second gate section, and a curved third gate section for guiding the control lever. The third gate section can be arranged between the first gate section and the second gate section and / or can merge into the first gate section and the second gate section. This allows an optimized movement path of the two door leaves to be implemented with minimal design effort. The movement path can be optimized, for example, to minimize acceleration forces generated during opening or closing and / or to avoid externally visible grinding marks on the two door leaves.

[0021] According to one embodiment, the first guide section and the second guide section can be aligned obliquely to one another. This can be understood to mean that the first and second guide sections enclose an angle with one another that deviates significantly from 90 degrees, for example by at least 5 degrees or by at least 10 degrees. The first and second guide sections can be aligned obliquely to one another in one or more spatial planes. For example, the first and second guide sections can be aligned obliquely to one another in that their respective longitudinal axes are aligned obliquely to one another. This has the technical effect that different rotational movements for actuating the pivoting mechanism can be generated by the first guide section and the second guide section.

[0022] According to one embodiment, the guide component can be mounted on the first wall part and / or the second wall part such that, when the sliding door system is installed, the first guide section extends parallel to a sliding direction of the door leaf support. For example, this can ensure that the alignment of the control lever relative to the sliding direction is essentially constant, i.e., the door leaves are merely moved along with the door leaf support, but not simultaneously pivoted toward or away from it, as long as the control lever is guided in the first guide section.

[0023] According to one embodiment, a geometry of the gate can be selected so that the first door leaf and the second door leaf each follow a straight first path section when the door leaf carrier is moved between a starting position in which the first door opening and the second door opening are unlocked and a first intermediate position, follow a curved second path section when the door leaf carrier is moved between the first intermediate position and a second intermediate position in which the first door leaf is opposite the first door opening and the second door leaf is opposite the second door opening, follow a straight third path section which is orthogonal to the first path section when the door leaf carrier is moved between the second intermediate position and an end position in which the first door leaf closes the first door opening and the second door leaf closes the second door opening.

[0024] The first intermediate position and the second intermediate position can each be located between the starting position and the end position in the direction of travel. The first intermediate position can be located between the second intermediate position and the starting position.

[0025] This design enables rapid opening and / or closing of the first and second door openings. "Rapid" in this context can be understood, for example, as a duration of 3 seconds or less. Furthermore, the forces acting on components of the sliding door system and / or the building wall during opening and / or closing can be significantly reduced compared to other possible movement paths of the two door leaves, resulting in lower manufacturing and maintenance costs. In other words, the two door leaves can be moved smoothly, or at least almost smoothly.

[0026] According to one embodiment, the second track section can be at least partially clothoid-shaped. However, other curve shapes that allow for minimizing the jerk are also possible, for example a C2 curve. In other words, the second track section can have a shape approximating a clothoid in one or more parts or even as a whole. For example, the curved track section can comprise a clothoid-shaped first part, into which the first track section merges, and / or a clothoid-shaped second part, into which the second track section merges. The first and second parts can either merge directly into one another or be connected to one another via a third part of the second track section. The third part can be clothoid-shaped or non-clothoid-shaped, for example, circular-arc-shaped.

[0027] According to one embodiment, the coupling device can comprise a switching mechanism that can be actuated by means of the control lever depending on a displacement direction of the door leaf support, for switching between a first geometry and a second geometry of the gate. The switching mechanism can be actuated, for example, during each change between a closing and opening process.

[0028] In other words, the coupling device can be designed such that the respective path followed by the door leaves when the door leaf support is moved depends on whether the door leaves are moving toward or away from the door openings. Different paths during opening and closing can, for example, cause the door openings to close faster than they open, or vice versa.

[0029] For example, the gate component, and thus the gate, can be mounted on the first and / or second wall part so that it can be moved between a first, preferably upper, position and a second, preferably lower, position, wherein the gate has a different geometry in the first position than in the second position. In this case, switching between the first geometry and the second geometry is achieved by simply moving the gate component. The movement can be achieved by means of the control lever and, additionally, by means of a spring mechanism.

[0030] The track for opening the door and the track for closing the door are therefore at different levels in the guide rail. At the end of the closing movement, the control lever presses on an inclined surface and thereby pushes the guide rail up or down to a different level so that when the control lever is then opened, the track for opening the door moves. At the end of the opening movement, the guide rail is moved back to its original level so that when the control lever is then closed, the track for closing moves. This moving back can be achieved using an inclined surface or by means of the spring mechanism. When the spring mechanism is used, in order to prevent the guide rail from moving back during opening, the control lever can engage a track limiter which prevents the guide rail from moving back while the door is opening.Towards the end of the opening, the travel limit stops, and the spring mechanism can move the gate back. Additionally or alternatively, a bistable retaining element can be provided to hold the gate at the upper or lower level.

[0031] Alternatively, the spring mechanism can be tensioned during the door closing process and held in place by the travel stop. In this case, the spring mechanism is less tensioned during the door opening process.

[0032] Alternatively, the control lever can be designed to be movable to a higher or lower level, and the gate can be designed to be fixed, i.e., non-movable. At the end of the opening or closing movement, the control lever is moved to the other, upper or lower, level by an inclined surface or a spring.

[0033] The control lever can be guided in one and the same gate in both positions of the gate component.

[0034] It is also possible for the guide component to comprise a first guide having the first geometry and a second guide having the second geometry. The switching mechanism can be configured to couple the control lever to either the first guide or the second guide depending on the direction of movement of the door leaf carrier, so that the control lever is guided either in the first guide or the second guide.

[0035] Alternatively, two differently shaped track flanks can simply be provided in the gate, which can guide a bolt mounted on the control lever. The bolt can then contact a different track flank during closing than during opening. The two track flanks can be shaped to create a hysteresis between opening and closing. For this purpose, the opening flank should be less steep than the closing flank, as otherwise the bolt could jam.

[0036] A combination of the examples described above for the implementation of the switching mechanism is also conceivable.

[0037] The pivot mechanism comprises several torsion bars mounted in the door leaf support so they can rotate around their longitudinal axes, and several pivot levers. Each pivot lever can be rigidly connected to one of the torsion bars at its first end and articulated to one of the door leaves at its second end. This type of pivot mechanism is robust and requires minimal design effort.

[0038] The control lever is firmly connected to a first of the torsion bars at its first end and pivotally mounted in the guide at its second end. For example, the control lever can be welded, soldered, and / or screwed to the first torsion bar at its first end. To simplify disassembly, the control lever and the first torsion bar can also be firmly connected to each other via a suitable coupling. This can further simplify the swivel mechanism.

[0039] The first door leaf is connected to the first torsion bar via at least one first pivot lever and to a second of the torsion bars via at least one second pivot lever. Additionally or alternatively, the second door leaf can be connected to a third of the torsion bars via at least one third pivot lever and to a fourth of the torsion bars via at least one fourth pivot lever. This makes the mounting of the door leaves significantly more stable than mounting via only one torsion bar and / or only one pivot lever per door leaf.

[0040] According to one embodiment, the first torsion bar and the second torsion bar, together with the first pivot lever and the second pivot lever, can form a first parallelogram guide for pivoting the first door leaf. Additionally or alternatively, the third torsion bar and the fourth torsion bar, together with the third pivot lever and the fourth pivot lever, can form a second parallelogram guide for pivoting the second door leaf. This efficiently enables the first or second door leaf to be and / or remain aligned at a defined angle to the building wall when the door leaf support is moved. This angle can change slightly depending on the horizontal position of the door leaf support.

[0041] Angle may vary slightly depending on a horizontal position of the door leaf support.

[0042] According to one embodiment, the first torsion bar can be coupled to the third torsion bar such that a rotational movement of the first torsion bar results in an opposite rotational movement of the third torsion bar. Additionally or alternatively, the second torsion bar can be coupled to the fourth torsion bar such that a rotational movement of the second torsion bar results in an opposite rotational movement of the fourth torsion bar. In other words, the respective torsion bars can be coupled to one another via a transmission. The transmission can, for example, be a gear or traction mechanism transmission or a combination of both. The transmission can be designed such that the respective rotational movement and the respective opposite rotational movement resulting from the respective rotational movement have the same (in terms of absolute value) rotational speed.This allows the rotational movement of the torsion bar driven by the control lever to be efficiently transmitted to one or more of the other torsion bars.

[0043] According to one embodiment, the first torsion bar can be coupled to the second torsion bar such that a rotational movement of the first torsion bar results in a concurrent rotational movement of the second torsion bar. Additionally or alternatively, the third torsion bar can be coupled to the fourth torsion bar such that a rotational movement of the third torsion bar results in a concurrent rotational movement of the fourth torsion bar. This makes it possible, using simple means, to move the first pivot lever together with the second pivot lever and / or the third pivot lever together with the fourth pivot lever. The respective rotational movement and the respective concurrent rotational movement resulting from the respective rotational movement can have the same rotational speed.

[0044] According to one embodiment, the pivoting mechanism can comprise at least one pair of spur gears for converting the rotary motion into counter-rotating and / or co-rotating rotary motion. In other words, one or more of the torsion bars can function as shafts of a spur gear drive. The spur gears of the spur gear pair can, for example, be mounted on different torsion bars and thus each be connected in a rotationally fixed manner. The spur gears of the different torsion bars can mesh with each other. Thus, the rotary motion of one torsion bar can be very easily converted into a counter-rotating motion of the other torsion bar. The conversion into a co-rotating motion can occur in a similar manner. Such a pivoting mechanism can be implemented cost-effectively, is space-saving, and low-wear.

[0045] It is possible for the sliding door system to additionally comprise at least one door frame element for at least partially framing the first door opening and / or second door opening. The door frame element can have a lip seal for sealing the respective door opening. The lip seal can be positioned such that it is compressed with a defined force by an outer edge portion of the respective door leaf when the respective door opening is closed by the respective door leaf.

[0046] Embodiments of the invention are described below with reference to the accompanying drawings, wherein neither the drawings nor the description are to be construed as limiting the invention. Fig. 1 shows a plan view of a sliding door system according to an embodiment of the invention in the installed state. Fig. 2 shows a section of the sliding door system from Fig. 1 when closed. Fig. 3 shows a section of the sliding door system from Fig. 1 in the open state. Fig. 4 shows a perspective view of a link component according to an embodiment of the invention.

[0047] The figures are merely schematic and not to scale. The same reference numerals designate identical or equivalent features in the various figures.

[0048] Fig. 1 shows a sliding door system 100 installed in a building wall 102. The sliding door system 100 includes a first wall portion 104 with a first door opening 106 and a second wall portion 108 with a second door opening 110, for example, in the form of wall panels or wall frames or a combination of both.

[0049] The two wall sections 104, 108 are arranged opposite each other, so that the first door opening 106 is opposite the second door opening 110, which together form a passage through the building wall 102. Furthermore, the two wall sections 104, 108 are separated from each other by a gap 112, which is dimensioned to provide sufficient space for the installation of components of the sliding door system 100.

[0050] The sliding door system 100 comprises a first door leaf 114 for closing the first door opening 106 and a second door leaf 116 for closing the second door opening 110. Fig. 1 shows the sliding door system 100 in a closed state in which both door openings 106, 110 are closed by the respective door leaf 114 and 116.

[0051] The two door leaves 114, 116 are pivotally mounted on a door leaf support 118, which is displaceably mounted in a horizontal displacement direction 122 along the intermediate space 112 by means of a linear guide device 120, for example in the form of a roller or sliding guide. The door leaf support 118 can be arranged at least partially between the wall parts 104, 108.

[0052] The door leaf carrier 118 can be displaced, for example, by means of an electric drive (not shown).

[0053] In order to be able to pivot the door leaves 114, 116 into and away from the respective door opening 114 or 116 in a controlled manner as a function of a sliding movement of the door leaf support 118, taking into account a given installation space, the sliding door system 100 further comprises a pivoting mechanism 124 for changing a respective position and / or orientation of the door leaves 114, 116 relative to the door leaf support 118, as well as a coupling device 126 for driving the pivoting mechanism 124 as a function of the sliding movement.

[0054] In this example, the pivot mechanism 124 includes a first pivot bar 128, a second pivot bar 130, a third pivot bar 132, and a fourth pivot bar 134.

[0055] The torsion bars 128, 130, 132, 134 are each mounted in the door leaf support 118 so as to be rotatable about their vertical longitudinal axis.

[0056] The first door leaf 114 is articulated to the first torsion bar 128 via a first pivot lever 136 and to the second torsion bar 130 via a second pivot lever 138, which together form a first parallelogram guide for guiding the first door leaf 114.

[0057] In an analogous manner, the second door leaf 116 is articulated to the third torsion bar 132 via a third pivot lever 140 and to the fourth torsion bar 134 via a fourth pivot lever 142, which together form a second parallelogram guide for guiding the second door leaf 116.

[0058] Each of the pivot levers 136, 138, 140, 142 can be firmly connected to the respective torsion bar at its first end and articulated to the respective door leaf at its second end.

[0059] The coupling device 126 comprises a guide component 144 with a guide 146, which can be implemented as a groove or slot in the guide component 144. The guide component 144 is here fixedly mounted outside the door leaf support 118 on an inner side of the first wall part 104 facing the intermediate space 112, above the first door opening 106 or the first door leaf 114. However, other mounting locations for the guide component 144 are also possible, for example, a building floor or a building ceiling.

[0060] The link component 144 can be mounted in such a way that it can be slightly displaced in the horizontal direction for adjustment purposes (indicated by two arrows).

[0061] To couple the link component 144 to the pivot mechanism 124, in this example, a control lever 148 is guided at its first end in the link 146, for example, via a guide pin mounted therein, and is connected at its second end in a rotationally fixed manner to the first torsion bar 128. In this way, the horizontal sliding movement of the door leaf support 118 can be converted into a rotational movement of the first torsion bar 128 according to the course of the link 146, whereby the first door leaf 114 is pivoted toward or away from the door leaf support 118.

[0062] In order to pivot the second door leaf 116 toward or away from the door leaf support 118 synchronously with the first door leaf 114, the first torsion bar 128 can be coupled to the third torsion bar 132 via a simple gear mechanism, for example in the form of a spur gear pair, for example such that the rotational movement of the first torsion bar 128 results in a corresponding counter-rotating movement of the third torsion bar 132.

[0063] The second torsion bar 130 and the fourth torsion bar 134 may be coupled together in a similar manner.

[0064] Additionally, the first torsion bar 128 can be coupled to the second torsion bar 130 and / or the third torsion bar 132 can be coupled to the fourth torsion bar 134 in a similar manner. For example, the coupling can be such that the rotational movement of one torsion bar results in a concurrent rotational movement of the other torsion bar.

[0065] The backdrop 146 can be adjusted in its course so that one or more of the following criteria are met: Rapid opening and / or smooth closing of the door leaves 114, 116 is enabled. The forces acting on the door leaves 114, 116 and / or the guide 146 during rapid opening are minimal. The movements of the door leaves 114, 116 during opening and closing are almost jerk-free. The door leaves 114, 116 do not touch the building wall 102 at any time during their movement. A gap between the door leaves 114, 116 and the respective wall section 104 or 108 in the closed state does not exceed a permissible maximum width to minimize the risk of injuries due to entrapment.

[0066] For example, the geometry of the gate 146 can be selected depending on a given building wall such that the door leaves 114, 116 describe a specific movement path 150 when opening and / or closing, which can be characterized by a straight first path section 150a, a curved second path section 150b and a straight third path section 150c.

[0067] As in Fig. 1 As shown by way of example, the first track section 150a can be aligned substantially parallel to the displacement direction 122 and / or substantially perpendicular to the third track section 150c.

[0068] For example, door leaves 114, 116 the first track section 150a, when the door leaf carrier 118 is moved between a starting position 152, in which the two door openings 106, 110 are open, and a first intermediate position 154, the second track section 150b, when the door leaf carrier 118 is moved between the first intermediate position 154 and a second intermediate position 156, in which the first door leaf 114 is opposite the first door opening 106 and the second door leaf 116 is opposite the second door opening 110, and the third track section 150c, when the door leaf carrier 118 is moved between the second intermediate position 156 and an end position 158, in which the first door leaf 114 is pivoted into the first door opening 106 and the second door leaf 116 is pivoted into the second door opening 110.

[0069] In order to ensure that the door leaves 114, 116 pivot as smoothly as possible, the second track section 150b can be at least partially clothoid-shaped.

[0070] Furthermore, it is possible for the second track section 150b to vary in its curvature depending on the direction in which the door leaf carrier 118 is displaced. For example, the guide 146 can be adapted so that opening occurs faster than closing. For this purpose, the coupling device 126 can comprise a switching mechanism (not shown) that can be actuated by means of the control lever 148 depending on the direction of displacement 122, for switching between a first geometry and a second geometry of the guide 146.

[0071] A particularly advantageous geometry of the gate 146, by means of which the above-mentioned effects can be produced, is shown in Fig. 2 , Fig. 3 and Fig. 4 As shown in Fig. 2 and Fig. 3 As shown, the link 146 can be divided into a straight first link section 202, which runs substantially parallel to the displacement direction 122, a straight second link section 204, which runs obliquely to the first link section 202, and a curved or arcuate third link section 206, which forms a transition between the first link section 202 and the second link section 204.

[0072] Fig. 4 shows the gate component 144 in an enlarged view. In this example, the gate component 144 is realized as a milled part with a milled gate 146.

[0073] Finally, it should be noted that terms such as "having," "comprising," etc., do not exclude other elements or steps, and terms such as "a" or "an" do not exclude a plurality. Furthermore, it should be noted that features or steps described with reference to one of the above embodiments may also be used in combination with other features or steps of other of the above embodiments.
