Sliding door system for installation in a building wall and method for maintaining a sliding door system

Description

[0001] The present invention relates to a sliding door system for installation in a building wall. Furthermore, the invention relates to a method for maintaining such a sliding door system.

[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 allows them to be pivoted into corresponding door openings in a building wall. To minimize the effort required for repairs and maintenance, the sliding door should be easily accessible from the outside and easily removable from the building wall.

[0003] Examples of various sliding doors are described in AT 507 815 A1, EP 1 731 703 A2, EP 2 871 316 A1, and EP 2 876 241 A1. DE 101 63 061 A1 shows a pivoting mechanism designed as a parallelogram guide, and the distance between the door leaves is determined by a guide rail depending on the position of the sliding door.

[0004] There may therefore be a need for a sliding door system for installation into a building wall that simplifies the repair and / or maintenance of a sliding door.

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

[0006] A first aspect of the invention relates to a sliding door system for installation in a building wall. The sliding door system comprises a sliding door having a first door leaf, a second door leaf, and a pivoting mechanism, as well as a housing for installation in the building wall and accommodating the sliding door. The housing has a first door opening and a second door opening opposite the first door opening. The sliding door is mounted in the housing so as to be displaceable on both sides beyond the first door opening and the second door opening. The pivoting mechanism is designed to convert a sliding movement of the sliding door into a pivoting movement of the first door leaf and the second door leaf, such that the first door leaf opens the first door opening and the second door leaf opens the second door opening in a first position of the sliding door and closes it in a second position of the sliding door.By deactivating the pivoting mechanism, the sliding door can be moved beyond the first door opening and the second door opening into a third position in which at least one component of the sliding door system to be serviced is accessible from outside the housing via the first door opening and / or the second door opening and / or from which the sliding door can be removed from the housing via the first door opening and / or the second door opening.

[0007] The housing can, for example, comprise at least a first wall section having the first door opening, a second wall section having the second door opening, and a housing frame to which the first and second wall sections are attached opposite one another at a defined distance from one another. A "wall section" can be understood as a flat element, for example in the form of a panel or a panel assembly. The housing can be inserted into a corresponding recess in the building wall. The sliding door can be slidably mounted in a space between the first wall section and the second wall section.

[0008] A "door leaf" can be understood as a flat, for example, plate-shaped element, which can also be referred to as a door panel. The height of the door leaf can, for example, be greater than the width of the door leaf, whereby the height and width can each be significantly greater than the thickness of the door leaf. The sum of the respective thicknesses of the first and second door leaves can be smaller than the distance between the first and second wall sections, so that both door leaves can be accommodated together in the space between the first and second wall sections.

[0009] In a first embodiment, a pivoting mechanism may comprise a linear guide that allows the first door leaf to change the distance to the second door leaf, preferably in a movement perpendicular to the surface of the first door leaf.

[0010] Preferably, several such linear guides are arranged between the first door leaf and the second door leaf. Such linear guides can be designed as linear plain bearings, linear ball bearings, or as a scissor mechanism.

[0011] In a second embodiment, the pivoting mechanism can have a parallelogram guide, whereby the door leaves are guided parallel to each other via at least two articulated arms arranged parallel to each other and of equal length. The articulated arms preferably have an angle of 45° or less to the plane of the first door leaf.

[0012] The distance between the first door leaf and the second door leaf is preferably determined by one or more guide rails, each of which engages a pin located on a door leaf. As the sliding door is moved, the pin is moved along a guide rail of the guide rail. The guide rail is a surface of the guide rail that preferably pushes the pin into different positions along the movement, thereby moving the first and second door leaves to the distance from each other assigned to the respective door position. The guide rails of the guide rails can be arranged above the door leaves in the door frame.

[0013] In the second position, in particular, the gate control moves the door leaves into a pivoted-out position, in which the first door leaf closes the first door opening and the second door leaf closes the second door opening. Shortly before reaching the second position, further movement of the sliding door through interaction with the gate control causes both door leaves to assume the pivoted-out position. However, any other design of the pivot mechanism is also possible. For example, the door can be pivoted out electronically via an electric or hydraulic drive.

[0014] The pivot mechanism can be deactivated, allowing the sliding door to pass through the second position to reach the third position without the door panels being swung out. Since the door panels do not swing out when the pivot mechanism is deactivated, the sliding door can be retracted into the right-hand section of the housing.

[0015] If the sliding door has an electronically controlled electric or hydraulic drive, the electronic control cannot activate the drive to deactivate the pivot mechanism. If the sliding door is activated by interaction with the gate control, the pivot mechanism can be deactivated by removing the pin from the gate, for example, by retracting the pin from the gate, or by moving or removing the gate.

[0016] It is possible for the sliding door to be displaceably mounted by means of a linear guide device which, for example, comprises an upper and lower guide rail. At least one of the guide rails can extend beyond the first and second door openings on both sides. A displacement path that the sliding door covers when displacing from the first position along a displacement axis to the third position can, for example, be longer than twice the width of the first or second door leaf. The displacement path can be shorter than three times the width of the first or second door leaf. The displacement path can, for example, be limited by one or more stops which prevent further displacement of the sliding door and / or the door leaves along the displacement axis in one or both directions.

[0017] The pivoting mechanism can, for example, be designed to move the first and second door leaves in opposite directions transverse to the sliding axis of the sliding door. 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.

[0018] The sliding door can, for example, comprise a door leaf support which is mounted in the housing by means of the linear guide device so as to be displaceable in two opposite directions along a horizontal displacement axis, for example in the space between the first and second wall part. The first and second door leaves can be pivotally mounted on the door leaf support by means of the pivoting mechanism. In this case, the pivoting mechanism can be designed to move the first and second door leaves together towards the door leaf support, i.e. to move them away from the respective door opening when the door leaf support is moved into the first position, and / or to move them away from the door leaf support, i.e. to move them towards the respective door opening when the door leaf support is moved into the second position.

[0019] The door leaf support can, for example, be a single movable support or a movable combination of several individual supports, for example in the form of a support frame.

[0020] In particular, if the pivoting mechanism is designed as a parallelogram guide, several parallelogram guides can be arranged such that a first parallelogram guide connects the first door leaf to the door leaf support, and a second parallelogram guide connects the second door leaf to the door leaf support. Even with linear guides, it is advantageous for a first linear guide to connect the first door leaf to the door leaf support, and a second linear guide to connect the second door leaf to the door leaf support. This allows the door leaf support to be moved in a straight line along the displacement axis.

[0021] The second position of the sliding door can be between the first and third positions. The second position can be closer to the third position than to the first position.

[0022] The sliding door can be displaceable into the first position by displacement in a first direction and / or into the third position by displacement in a second direction opposite to the first direction, for example along the horizontal displacement axis.

[0023] In other words, it is possible for the sliding door to be moved at least partially beyond a left outer edge of the first and second door openings by moving it into the first position and at least partially beyond a right outer edge of the first and second door openings by moving it into the third position, or vice versa.

[0024] For safety reasons, the pivoting mechanism should only be deactivatable when the sliding door is in the fully or partially open state, i.e. in the first position or an intermediate position between the first and second positions, but not in the second position, i.e. in the closed state.

[0025] A part of the sliding door that can be moved beyond the first and second door openings can comprise at least a part of the first and / or second door leaf.

[0026] It is possible for the first and second door leaves to be completely outside the first and second door openings in the first position and / or completely between the first and second door openings in the second position. In the third position, the first and second door leaves can, for example, be partially outside the first and second door openings and partially between the first and second door openings. In other words, it is possible for the first and second door openings to still be open a crack in the third position.

[0027] The part of the sliding door which is accessible from outside the housing via the first and / or second door opening in the third position may, for example, be a part which is not accessible from outside the housing via the first door opening and / or the second door opening in the first and / or second position, for example because it is then covered by the housing or by at least one or both door leaves.

[0028] In addition, the sliding door system may comprise an electric drive device for generating the sliding movement of the sliding door, for example the door leaf carrier.

[0029] The electric drive device can comprise an electric motor and electrical and / or electronic components for controlling the electric motor, for example in the form of a control unit or a transformer. It is possible for one or more of these components to be arranged on the sliding door, for example, on the door leaf support. By moving the sliding door to the third position, these components can be moved far enough to be accessible to a technician from outside the housing via the first and / or second door opening.

[0030] Such a sliding door system ensures simple yet secure installation, maintenance, and / or repair. The sliding door can be installed and removed by a single person in just a few simple steps. However, the sliding door system remains burglar-proof, as maintenance and / or repairs are only possible when the sliding door is unlocked.

[0031] A second aspect of the invention relates to a method for servicing a sliding door system according to an embodiment of the first aspect of the invention. The method comprises at least the following steps: deactivating the pivoting mechanism to enable the sliding door to be moved beyond the first door opening and the second door opening into the third position, and moving the sliding door beyond the first door opening and the second door opening into the third position to enable access to the at least one component to be serviced via the first door opening and / or the second door opening from outside the housing and / or removing the sliding door from the housing via the first door opening and / or the second door opening. This ensures access to components of the sliding door system to be serviced with just a few simple steps. Furthermore, easy removal of the sliding door as a whole is enabled.

[0032] Features of the method according to an embodiment of the second aspect of the invention can also be features of the sliding door system according to an embodiment of the first aspect of the invention and vice versa.

[0033] Possible features and advantages of embodiments of the invention may be considered, among other things and without limiting the invention, as being based on the ideas and findings described below.

[0034] According to the invention, the first door leaf and the second door leaf are arranged in the first position at least partially in a left housing section of the housing located to the left of the first door opening and the second door opening, in the second position at least partially between the first door opening and the second door opening and in the third position at least partially in a right housing section of the housing located to the right of the first door opening and the second door opening.

[0035] The pivot mechanism serves to change the distance between the first door leaf and the second door leaf. The pivot mechanism thus allows the door leaves to be brought close enough together to reach the first position so that the door leaves can be inserted into the left-hand housing section. The pivot mechanism also allows the door leaves to be spread apart in the second position until the outer surfaces of the door leaves are flush with the outer surface of the housing. Sliding doors with corresponding pivot mechanisms are known from the publications cited above. The pivot mechanism can also be called a spreading mechanism.

[0036] The terms "left" and "right" here are to be understood in relation to a sliding axis along which the sliding door can be moved. For example, in the first position, the first and second door leaves can be arranged entirely within the left housing section without protruding into the first and second door openings. In contrast, in the third position, only a front part of the sliding door can be arranged in the right housing section. A rear part of the sliding door, facing the left housing section, can be arranged between the first and second door openings and thus be accessible from the outside, i.e., from outside the housing. For example, predominantly movable parts of the sliding door system or other components requiring maintenance can be arranged in this rear part and can be moved together with the sliding door.In the third position, the left housing section can also be accessible from outside the housing via the first and / or second door opening. To further simplify maintenance, the housing itself can house components that are predominantly immobile or do not require maintenance during the intended service life of the sliding door system.

[0037] According to the invention, the sliding door is designed so that the component to be serviced is only accessible in the third position.

[0038] In other words, the component to be serviced can be attached to the left housing section or to a part of the sliding door that remains in the first position and in the second position of the sliding door in the left housing section of the housing.

[0039] The left housing section is only accessible when the sliding door is moved to the third position, allowing access to the left housing section.

[0040] When the sliding door is moved from the second position to the third position, areas of the door are accessible that would otherwise be inaccessible. For example, the left section of the housing and a part of the sliding door that would otherwise always remain in the left section of the housing are accessible. The component requiring maintenance is only accessible in the third position, i.e., not in the first or second positions.

[0041] According to one embodiment, the sliding door can be mounted in the housing by means of a linear guide device, allowing it to be displaced on both sides beyond the first door opening and the second door opening. The linear guide device can be arranged at least partially in the right-hand housing section. For example, at least one guide rail or at least one guide shoe of the linear guide device can extend into the right-hand housing section.

[0042] According to one embodiment, a gap between an edge section of the first door opening and an edge section of the second door opening can be covered by at least one cover plate. In other words, the housing in the region of the first and second door opening can be covered or enclosed by one or more cover plates in such a way that when the sliding door is fully or partially open, i.e. when it is in the first position or between the first and second positions, no view or access into the interior of the housing is possible, for example into the right-hand housing section. The cover plate can be part of a frame, such as a frame headliner or a side frame wall.

[0043] Preferably, the cover plate covers the right housing section of the housing. This protects the right housing section from dirt and prevents the user from seeing into the right housing section.

[0044] According to one embodiment, the cover plate can be attached to the housing by means of a locking mechanism and can be removed from the housing by unlocking the locking mechanism. The locking mechanism can only be unlocked when the sliding door is in the first position and / or between the first position and the second position. The locking mechanism can be unlocked using a special tool or a special key. For example, a receptacle for the tool or key can be concealed by the two door leaves when the sliding door is closed, and can no longer be concealed by the two door leaves when the sliding door is fully or partially open, and thus be accessible from the outside.

[0045] According to one embodiment, the first door leaf and the second door leaf can be spaced apart from one another in the second position transversely to a sliding axis along which the sliding door is displaceable than in the first position and / or the third position. In other words, the first and second door leaves can be at least partially recessed into the respective door opening when the sliding door is closed, for example, to seal the door openings sufficiently soundproof and / or airtight. The distance in the width direction of the housing between the two door leaves in the pivoted-in state can be selected such that they can be displaced beyond the door openings in the housing in both directions of the sliding axis.

[0046] According to one embodiment, the at least one component to be serviced can be arranged on the sliding door. This means that the component(s) to be serviced can be moved along with the sliding door. Access to this component(s) is thus enabled by simply moving the sliding door to the third position. Apart from deactivating the pivoting mechanism, which can be deactivated, for example, by simply flipping or unhooking a lever, no further disassembly steps are required.

[0047] According to one embodiment, the sliding door system can further comprise an electric drive device for generating the sliding movement. The at least one component to be serviced can be a component of the electric drive device. Thus, individual components of the electric drive device, such as a drive motor, a drive controller, or a transformer, can be serviced, replaced, and / or repaired with minimal effort.

[0048] According to one embodiment, the pivoting mechanism can be at least partially accessible via the first door opening and / or the second door opening from outside the housing when the sliding door is in an intermediate position between the first position and the second position. This can be understood to mean that access to the pivoting mechanism is not possible, or at least not possible from outside the housing, in particular not from an outside of the building wall, if the sliding door is in the second position, i.e. in the closed state. For example, after it has been unlocked, for example by means of a door key, the sliding door can first be moved from the second position towards the first position, for example by means of the electric drive device, until the first and second door leaves are fully pivoted in.In this intermediate position of the sliding door, the pivoting mechanism can then be deactivated so that the first and second door leaves are not pivoted out again when moved in the opposite direction, i.e. towards the second and third positions, which would possibly prevent further movement into the third position.

[0049] According to one embodiment, the housing can further comprise a first door frame that at least partially frames the first door opening. In the second position, the first door leaf can be at least partially recessed into the first door frame. Additionally or alternatively, the housing can further comprise a second door frame that at least partially frames the second door opening. In the second position, the second door leaf can be at least partially recessed into the second door frame. "Door frame" can be understood, for example, as a door frame or a door frame element, for example in the form of a sheet metal or wooden part. It is possible for the first and / or second door frame to comprise a lip seal for sealing the respective door opening. The lip seal can, for example, be compressed by an outer edge portion of the respective door leaf when the respective door leaf is at least partially recessed into the respective door frame.This allows a gap between the housing and the closed sliding door to be effectively sealed, for example for sound insulation or fire protection purposes.

[0050] According to one embodiment, the pivoting mechanism can be designed to convert the sliding movement into the pivoting movement such that, in the second position, an outer surface of the first door leaf, together with an outer surface of the housing adjacent to the first door opening, forms a first flat surface. Additionally or alternatively, the pivoting mechanism can be designed to convert the sliding movement into the pivoting movement such that an outer surface of the second door leaf, together with an outer surface of the housing adjacent to the second door opening, forms a second flat surface. This can increase the burglar resistance of the sliding door system compared to designs with non-flush door leaves. Furthermore, this can ensure that the door leaves, when closed, stand out barely noticeably from the surrounding building wall, if desired.

[0051] According to one embodiment, the method may further comprise removing the sliding door from the housing via the first door opening and / or the second door opening, starting from the third position. In this way, the sliding door can be removed from the housing in its entirety with just a few simple steps and minimal effort.

[0052] According to one embodiment, the sliding door can be moved from the third position toward the first position and rotated into the first door opening and / or the second door opening. In addition, the sliding door can be tilted in a suitable manner. The sliding door can be removed, for example, using a separate removal mechanism and / or the linear guide device (see above). For example, the sliding door can be mounted at two bearing points in the linear guide device, whereby by releasing the connection of the sliding door to one of the bearing points, the other bearing point can act as a pivot point around which the sliding door can then be rotated. However, any other embodiments familiar to those skilled in the art are also possible.

[0053] According to one embodiment, the method may further comprise inserting the sliding door into the housing via the first door opening and / or the second door opening, whereby the sliding door can be moved into the third position, and subsequently activating the pivoting mechanism. Insertion may, for example, be performed in the reverse order of removal. This ensures easy replacement of the sliding door.

[0054] 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 built-in sliding door system according to an embodiment of the invention in the open state. Fig. 2 shows the sliding door system Fig. 1 when closed. Fig. 3 shows the sliding door system Fig. 1 in a maintenance state. Fig. 4 shows a side view of the sliding door system from Fig. 3 . Fig. 5 shows a perspective view of a sliding door system according to an embodiment of the invention with the sliding door swung out. Fig. 6 shows the sliding door system Fig. 5 with the sliding door swung out even further. Fig. 7 shows a top view of the sliding door system from Fig. 6 .

[0055] The figures are merely schematic and not to scale. The same reference numerals designate identical or equivalent features in the various figures.

[0056] Fig. 1 shows a sliding door system 100 with a sliding door 102 and a housing 104 that is installed in a building wall 106. The housing 104 has a first door opening 108 and a second door opening 110, which is opposite the first door opening 108. In this example, the sliding door 102 is mounted within the housing 104 so that it can be moved along a horizontal displacement axis 112 on both sides, here both to the left and to the right, beyond the two door openings 108, 110.

[0057] The sliding door 102 comprises a first door leaf 114 for closing the first door opening 108 and a second door leaf 116 for closing the second door opening 110. The two door leaves 114, 116 are positioned opposite each other in a direction transverse to the sliding axis 112. The two door leaves 114, 116 can be displaced simultaneously and synchronously with each other along the sliding axis 112 relative to the door openings 108, 110. The sliding door 102 further comprises a pivoting mechanism 118 which is designed to convert a sliding movement of the sliding door 102, which can be caused, for example, by means of an electric drive device 120 upon actuation of a corresponding door switch, into a pivoting movement of the two door leaves 114, 116 (indicated by two arrows), so that the door openings 108, 110 are either closed or opened depending on the sliding direction of the sliding door 102.

[0058] The door leaves 114, 116 can, for example, each be pivoted in or out via a parallelogram guide and a cam control coupled to the respective parallelogram guide. However, any other design of the pivot mechanism 118 is also possible.

[0059] Additionally, the sliding door system 100 includes a first door frame 122, which at least partially frames the first door opening 108, and a second door frame 124, which at least partially frames the second door opening 110. A suitable door seal for sealing the respective door leaf 114, 116 against the housing 104 and / or the building wall 106 can be integrated into at least one of the two door frames 122, 124.

[0060] Fig. 1 shows the sliding door 102 by way of example in the open state, in which the two door leaves 114, 116 are arranged completely in a housing section 126, here on the left, which is located to the left of the two door openings 108, 110, and thus completely expose the two door openings 108, 110.

[0061] Starting from this first position, the sliding door 102 can be moved to a second position as shown in Fig. 2 The second position corresponds to a closed state of the sliding door 102, in which the first door opening 108 is completely closed by the first door leaf 114 and the second door opening 110 is completely closed by the second door leaf 116.

[0062] It is possible that when the sliding door 102 is moved into the second position, the two door leaves 114, 116 are each partially recessed into the corresponding door frame 122 or 124 by corresponding pivoting by means of the pivot mechanism 118 in order to seal the sliding door 102 in a suitable manner and / or to ensure that the building wall 106 appears as flat as possible when the sliding door 102 is closed, i.e. when the sliding door 102 is closed, there is as little step as possible between a respective outer surface of the door leaves 114, 116 and a corresponding outer surface of the building wall 106. An outer surface of one of the door leaves 114, 116 can be aligned with an outer surface of the door frame 122, 124 receiving the door leaf 114, 116.

[0063] In order to maintain, repair and / or remove the sliding door 102, the sliding door 102 is further displaceable into a third position, as shown by way of example in Fig. 3 is shown.

[0064] For this purpose, the sliding door 102 can, for example, first be unlocked and then, starting from the second position, moved a short distance toward the first position. This can be done manually or by means of the electric drive device 120, so that the door leaves 114, 116 are retracted from the respective door opening 108 and 110 by means of the pivoting mechanism 118. In doing so, their mutual distance transverse to the sliding axis 112 decreases.

[0065] The pivoting mechanism 118 can then be deactivated in a suitable manner, for example by detaching a control lever from the guide rail control. If the sliding door 102 is then moved in the opposite direction, i.e., toward the second position, the door leaves 114, 116 remain in their previous, pivoted-in state due to the deactivated pivoting mechanism 118, so that the sliding door 102, or at least a front part thereof, can be pushed beyond the two door openings 108, 110 into a housing section 300, here on the right, which is located to the right of the two door openings 108, 110. This allows access to at least a rear part of the sliding door 102, in which, for example, the electric drive device 120 or other components of the sliding door system 100 requiring maintenance can be arranged, via at least one of the two door openings 108, 110 from outside the housing 104 (in Fig. 3 indicated by two arrows).

[0066] Furthermore, in this third position, the sliding door 102 can be removed from the housing 104 very easily as a whole, ie without having to be further disassembled into its individual parts, as is shown by way of example in Fig. 5 bis Fig. 7 is shown.

[0067] In the Fig. 4 The side view of the sliding door system 100 shown shows a section of a door leaf support 400, on which the two door leaves 114, 116 can be pivotally mounted by means of the pivot mechanism 118 (not shown here). Components to be serviced, such as a drive motor 402, a drive controller 404, or a toroidal transformer 406, which may be parts of the electric drive device 120, or other mechanically movable, electrical, and / or electronic components, can be attached to the rear part of the door leaf support 400. This rear part is conveniently accessible from the outside via the two door openings 108, 110 in the third position of the sliding door 102, as shown here.

[0068] Furthermore, a lower guide 408 and an upper guide 410 arranged offset therefrom are shown, which guide the sliding door 102, more precisely the door leaf support 400, when it is moved along the displacement axis 112.

[0069] An example is Fig. 4 The lower guide 408 is arranged in the left housing section 126, and the upper guide 410 is arranged between the left housing section 126 and the right housing section 300. However, it is also possible for at least one of the two guides 408, 410 to be arranged at least partially in the right housing section 300.

[0070] In order to remove the sliding door 102 from the housing 104, it can, for example, be moved from the third position a little way back towards the first position and in doing so be swung out of the housing 104 in a suitable manner, as shown in Fig. 5 bis Fig. 7 is illustrated.

[0071] The sliding door 102 can be inserted into the housing 104 in the reverse order to its removal.

[0072] For a better overview, the building wall 106 was Fig. 2 bis Fig. 7 omitted.

[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. Reference signs in the claims are not to be considered as limitations.
