EP3882425B1 - Sliding door assembly - Google Patents

Description

The invention relates to a sliding door arrangement with a frame and a door leaf that can be displaced relative to the frame.

Sliding door assemblies of the type mentioned are known from the prior art, for example DE 201 18 906 U1 , showing a sliding door assembly with a leaf manually slidable relative to the frame. In addition, it is off EP 2 933 417 A1 a sliding door arrangement with a frame and a wing that can be displaced relative to the frame is known, wherein the wing can be moved by a motor by means of a motor drive. This increases the ease of use. However, the wing is only supplied with energy in the closed position in order to charge a battery arranged on the wing. As a result, if the sash is opened for a longer period of time, the battery voltage drops so much due to the energy consumption of components that the sash can no longer be moved by motor and has to be pushed closed manually in order to be recharged. There is therefore a need for optimization.

Furthermore, it is off DE 100 60 865 A1 a sliding wall known, which consists of two or more glass sliding wall panels with a carriage. The individual walls are movable and stackable via a switch. One of the carriages is equipped with a motor, with current collector profiles being integrated into the roller of the carriage. The current collector profiles create an electrical connection between the resilient power lines integrated in the running profiles and the resilient interfaces on the motor.

The object of the invention is to ensure a permanent power supply of components arranged on the leaf side in a sliding door arrangement with simple structural means.

The invention solves this problem by a sliding door arrangement with the features of claim 1. The sliding door arrangement has a (stationary) frame (fixed frame), a door leaf that can be moved (horizontally) relative to the frame, which is coupled to a guide slider and, by means of the guide slider, in a frame arranged guide rail is guided, and at least one wing-side arranged consumers of electrical energy (at least one wing-side arranged and to be supplied with electrical energy component).

The sliding door arrangement is characterized in that conductor elements ("conductor tracks") are arranged on or in the guide rail, which extend along the longitudinal direction of the guide rail (direction of displacement), and that the guide slider first contact elements and electrically second contact elements connected thereto, wherein the first contact elements are in contact with the conductor elements, wherein the second contact elements are in contact with contact surfaces arranged on the leaf side, which are electrically connected to the consumer, and wherein the second contact elements extend along a direction of extension towards the door leaf and are elastic and deformable along the direction of extension, for example reversibly compressible, in order to compensate (along the direction of extension) a distance between the guide slider and contact surfaces.

Thus, a permanent transmission of electrical energy from the frame to the door leaf is created with simple design means. Because electrical energy is transmitted on or in the guide rail, electrical contact points are largely protected from environmental influences. There is no need for trailing cables or the like. A sliding contact with the conductor elements is realized by the first contact elements. Since the second contact elements are reversibly deformable, electrical energy can be transmitted from the frame to the door leaf, at least to a certain extent, even if the frame and the door leaf are at different distances from one another. Thus, the second contact elements can be used to compensate for manufacturing and assembly tolerances and, for example, also a sash lift (lifting movement by raising or lowering a sliding sash). It is a permanent transmission of electrical energy possible from the frame to the leaf, regardless of the sliding position of the door leaf.

Since the guide slider is coupled to the door leaf, the guide slider moves with the door leaf when it is moved. The first contact elements are in particular formed on a different side of the body of the guide slider than the second contact elements. The guide slider can be made of an electrically insulating material, for example plastic.

The contacting is in particular designed in such a way that a first contact element is in (sliding) electrical contact with one of the conductor elements. In each case, a first contact element is electrically connected to a second contact element. The conductor elements can, for example, each be designed as a round bar, for example made of metal.

The guide rail is in particular designed as a profile, for example as an extruded profile, with the guide rail being open on the front side and on one longitudinal side. The guide rail has in particular a base section (rear wall), wall sections (side walls) protruding therefrom and further wall sections which protrude into the clear cross-section of the guide rail (grip sections). The guide rail can, for example, be designed as an aluminum profile.

The door leaf is in particular a lifting/sliding leaf that can not only be moved (horizontally) relative to the frame, but can also be raised and lowered. When the door leaf is raised, it can be moved (horizontally). In a lowered state of the door leaf, sealing of the door leaf on the frame can be achieved or simplified. In addition, the door leaf can be locked on the frame when it is lowered and in the closed position (door leaf pushed closed). For this purpose, locking elements that correspond to one another can be provided on the door leaf and on the frame.

The door leaf can be moved or shifted via one or more carriages along a running rail arranged in the direction of gravity below the door leaf on the frame. The guide rail is arranged in the direction of gravity above the door leaf on the frame, with the door leaf being guided on the guide rail by means of the guide slider and being able to be moved or shifted along the guide rail.

Within the scope of a preferred embodiment, the first contact elements can each be designed as metal strips, preferably convexly curved. This creates a simple and robust contact element which can compensate for manufacturing and assembly tolerances to a certain extent (spring effect). This contributes to reliable electrical contact between the first contact elements and the conductor elements. The spring action ensures that the first contact elements are in contact with the conductor elements even in the case of mechanical wear (abrasion) (transmission of electrical energy possible).

Alternatively or additionally, the second contact elements can each be designed as metal strips shaped into a ring or into an ellipse. A structurally simple and stable contact element is thus created which can be reversibly deformed over a comparatively large area. This favors a compensation of manufacturing and assembly tolerances and a compensation of the wing stroke. The second contact elements are so dimensionally stable transversely to the direction of extension (direction of lift of the door leaf) that the risk of the second contact elements buckling is largely reduced. It is thus possible to prevent the second contact elements from touching one another and initiating a short circuit.

Advantageously, the first contact elements and the second contact elements can each be electrically connected to one another by means of a contact block, with a first contact element and a second contact element being fastened to the contact block, in particular being screwed. In this way, a simple mechanical and electrical connection of the contact elements is created. By arranging the contact blocks in corresponding recesses in the guide slider, the contact blocks and the contact elements can be secured on the guide slider.

The first contact elements can each be screwed to the contact block at one end (attachment section) by means of a screw. The first contact elements can each extend from this end (fixed end) to a free end. A depression for the fastening section of the first contact element can be formed on the contact element. This can prevent the first contact element from twisting relative to the contact block.

The second contact elements can each be interrupted at one point, with outwardly protruding lugs being formed at the interruption. These lugs can be inserted into an opening on the guide slider and rest against the contact block. The second holding elements can each be screwed to the contact block by means of a holding plate covering the interruption and a screw passed through the interruption. By positioning the lugs in the openings in the guide slider ("forced position"), the correct position is ensured and the second contact elements cannot twist.

Expediently, the first contact elements can be offset from one another along the central longitudinal direction of the guide slider (displacement direction). As a result, the overall height of the guide slider can be kept low. This also reduces the risk of short circuits.

Advantageously, the second contact elements can be offset from one another along the central longitudinal direction of the guide slider (displacement direction). As a result, a lower local component weakening of the guide slider can be achieved. In addition, the risk of a short circuit due to the second contact elements touching one another is reduced.

Within the framework of a preferred embodiment, concave recesses can be formed in the guide slider that extend along the central longitudinal direction of the guide slider (displacement direction), in each of which a second contact element is seated. This facilitates alignment and assembly of the second contact elements. In addition, a safeguard against twisting or bending of the second contact elements is thus created. The second contact elements are arranged in sections in the recess and, starting from the recess, extend away from the guide slider. The recesses are offset from one another along the central longitudinal direction of the guide slider (direction of displacement).

A drive element (e.g. a toothed wheel) can expediently be arranged in the guide slider, which drives an output element fastened to the frame, for example a toothed belt which has open ends and is fastened to the frame. As a result, a drive function is also integrated into the guide slider. The gear can be rotatably coupled to a shaft or have a shaft section, via which the gear wheel can be coupled to a wing-side electric drive unit. Deflection rollers, corresponding recesses and a retaining plate can also be provided on the guide slider.

Advantageously, the conductor elements can be attached to or in the guide rail by means of an electrically insulating conductor element carrier that extends along the guide rail, wherein the conductor elements can be attached to the conductor element carrier by means of a snap connection and/or the conductor element carrier can be attached to the guide rail by means of a snap connection can. This facilitates assembly, as the components (detachable or non-detachable) can be joined in a form-fitting manner. The conductor element carrier is designed as an elastically deforming joining part, for example made of plastic.

Longitudinally oriented grooves for the conductor elements can be formed on the conductor element carrier, each of which more than half encompasses an (inserted) conductor element in cross section, for example by more than 180°. A web extending along the longitudinal direction of the guide rail and having a peg-shaped cross section can be formed on the guide rail, with a corresponding web receptacle being formed on the conductor element carrier, which encompasses the web (in the inserted state) in cross section by more than half, e.g. by more than 180° .

As part of a preferred embodiment, a contacting unit can be attached to the narrow side of the door leaf (upper side of the leaf) facing the guide rail (in the installed position), the contacting unit having an insulating carrier plate and two contact plates attached to the carrier plate, with the contact surfaces each facing through one of the guide rails Surface of the contact plates are formed. This favors a structurally simple and robust configuration of the contact surfaces. Terminal lugs for electrical connection to wing-side energy consumers, such as a controller, can be formed on the contact plates.

Advantageously, a pocket can be formed on the carrier plate for each contact plate, which accommodates the contact plate at least in sections, one or more latching lugs being formed on each pocket, so that the contact plate can be fastened or is fastened to the carrier plate by means of a snap-in connection. This facilitates manufacture and assembly.

An electrical power supply (e.g. a power supply unit) can expediently be provided on the frame side, which is electrically connected via connecting lines to (electrical) contact elements of a plug-in unit (connector plug), the plug-in unit being able to be pushed into the guide rail and the contact elements being pushed into the guide rail come into electrical contact with the conductor elements. This contributes to a simple electrical contact and facilitates the assembly. The plug-in unit can be designed to be complementary (partially complementary or fully complementary) to the guide rail. The contact elements of the plug-in unit can be designed as concave metal strips. The contact elements of the plug-in unit can structurally correspond to the first contact elements of the guide slider.

The contact elements can each be attached to the plug-in unit by means of a contact block, with the contact block being inserted into an opening provided for this purpose in the plug-in unit. The contact blocks can correspond to the contact blocks described above in connection with the first and second contact elements on the guide slider. The production can be favored by a higher proportion of identical parts.

A controller arranged on the wing side can advantageously be provided as a consumer, which has a data transmission device, the electrical energy supply (e.g. power supply unit) likewise having a data transmission device, the data transmission devices each being designed to transmit and receive data signals modulated onto electrical lines and wherein the data transmission devices are electrically connected to one another. Bidirectional communication is thus possible between the controller and the power supply. It cannot with the electrical connection only electrical energy but also signals can be transmitted. In this way, the energy supply (e.g. the power pack) and the controller can exchange signals, e.g. control signals. The electrical connection can include the connecting lines, the plug-in unit, the conductor elements, the guide slider, the contacting unit and connecting lugs extending therefrom, to which a wing-side control is connected.

Expediently, an electric drive unit for moving the door leaf can be arranged on the wing side as a (further) consumer, with the drive unit driving the drive element (gear wheel) arranged in the guide slider. This allows the door leaf to be moved automatically. The electric drive unit can be controlled by the controller. The drive unit can have an electric motor, which can optionally be followed by a reduction gear (reduction gear between electric motor and drive element).

Advantageously, a (manually or motor-operated) clutch device can be provided between the electric drive unit and the drive element (gear wheel), by means of which a power flow can be established between the drive unit and the drive element and a power flow between the drive unit and the drive element can be interrupted. This makes it easier to connect and disconnect the electric drive unit from the vehicle Guide slider or from the drive element. This favors assembly of the door leaf on the frame and also its disassembly.

Within the scope of a preferred embodiment, an accumulator arranged on the wing side can be provided for supplying energy to consumers of electrical energy arranged on the wing side, for example the controller and/or the electric drive unit. As a result, the door leaf can also be moved automatically if a mains-connected energy supply, for example the mains power supply, is disrupted. In addition, the current levels to be transmitted can be kept low as a result, so that the electrical lines and contacts can be designed to be smaller.

In concrete terms, the energy supply of the sliding door arrangement can be set up in such a way that the electrical power provided by the energy supply to the controller or the battery would not be sufficient to drive the electrical drive unit. An energy supply to these components is ensured by the accumulator, which can be permanently charged via the electrical connection between the frame and the door leaf.

Advantageously, a further door leaf can be provided on the sliding door arrangement, which is guided on the frame and can be displaced relative to the frame. This creates a lift/sliding door combination with several door leaves.

The other door leaf can be designed analogously to the door leaf described above. The additional door leaf can thus have the components that the (first) door leaf described above also has.

For example, the further door leaf can have a control arranged on the leaf side, which has a data transmission device which is designed to send and receive data signals modulated onto electrical lines and is connected to data transmission devices for the power supply on the frame (e.g. power pack) and/or the control on the leaf side of the (first ) door leaf is electrically connected.

In this way, data signals can be transmitted not only between the power pack and the controller of the (first) door leaf, but also between the (first) door leaf and the other door leaf. In this way, a combination of several door leaves that are electrically connected to one another can exchange control and/or status information.

The drive components arranged in the guide slider and the coupling device can be designed as in EP 2 933 417 A1 described, the disclosure of which is hereby incorporated by reference.

figure 1 FIG. 12 shows a sliding door assembly, designated generally by the reference numeral 10. FIG. The sliding door arrangement 10 has a stationary frame 12 (fixed frame 12) and a door leaf 14 which can be displaced horizontally relative to the frame 12.

The frame 12 includes a lower frame member 16, an upper frame member 18 and two side frame members 20 (only one side frame member 20 shown). The door leaf 14 has a leaf frame 22 which delimits a leaf panel 24, for example a glazing. The wing frame 22 has a lower profile 26, an upper profile 28 and side profiles 30,32.

A running rail 34 is arranged on the lower frame part 16 of the frame 12 . The door leaf 14 has two carriages 36, 38 on the lower profile 26, which run in the running rail 34. The door leaf 14 can be displaced relative to the frame 12 by means of the carriages 36 , 38 . A guide rail 40 is arranged on the upper frame part 18 of the frame 12 . A guide slider 42 is slidably guided in the guide rail 40 . The door leaf 14 is coupled to the guide slider 42 and is thereby guided at the upper end of the door leaf 14 .

The door leaf 14 is designed as a lifting/sliding leaf, which is not only horizontally displaceable, but can also be raised and lowered. When the door leaf 14 is in a raised state, it can be moved horizontally relative to the frame 12 . When the door leaf 14 is in a lowered state, effective sealing of the door leaf 14 relative to the frame 12 is promoted.

An electrical power supply 44 in the form of a power supply unit, for example a 230 volt/24 volt power supply unit, is arranged in the lateral frame part 20 of the frame 12 . This is electrically connected via connection lines (not shown) to a plug-in unit 46 which is plugged into the guide rail 40 at the front. A contacting unit 48 is arranged on the upper profile 28 of the door leaf 14 . The door leaf 14 has several components on or in the side profile 32 that have to be supplied with electrical energy, namely an electric drive unit 50, an electric/electronic control 52 and a battery 54.

Figures 2a and 2b show the guide rail 40 in a schematic sectional view. The guide rail 40 has a base section 56, wall sections 58, 60 protruding therefrom and further wall sections 62, 64 which protrude into the clear cross-section of the guide rail 40 (gripping sections 62, 64). The guide rail 40 can, for example, be designed as an aluminum profile.

Two conductor elements 66 , 68 are arranged in the guide rail 40 and extend along the longitudinal direction of the guide rail 40 . The conductor elements 66 , 68 are fastened in the guide rail 40 by means of an electrically insulating conductor element carrier 70 which extends along the guide rail 40 . Fastening is by means of snap connections.

The conductor element carrier 70 is designed to be elastically deformable, for example made of plastic. Longitudinal grooves 72, 74 are formed on the conductor element carrier 70, in each of which a conductor element 66, 68 can be inserted. The longitudinal grooves 72, 74 surround the conductor elements 66, 68 more than half in the inserted state in cross section. Also formed in the guide rail 40 is a web 76 which extends in the longitudinal direction of the guide rail 40 and has a peg-shaped cross section. A corresponding web receptacle 78 is formed on the conductor element carrier 70 and, in the inserted state, encompasses more than half of the cross section of the web 76 .

figure 3 shows the plug-in unit 46 on its own. The plug-in unit 46 or its housing 80 is designed to complement the guide rail 40, so that the plug-in unit 46 can be pushed into the guide rail 40 at the front (cf. Fig.4 ).

The plug-in unit 46 has electrical contact elements 82, 84 which are designed as concave metal strips are (cf. Fig.3 ). The contact elements 82, 84 are each attached at one end to the plug-in unit 46 by means of a screw.

The contact elements 82, 84 are each fastened to the plug-in unit 46 by means of a contact block 81, 83, the contact block being inserted into an opening provided for this purpose (without a reference number) in the plug-in unit 46. The contact blocks 81, 83 can structurally correspond to the contact blocks 100, 102, which are described below in connection with the guide slider 42.

The contact elements 82, 84 are arranged offset to one another along the central longitudinal direction of the plug-in unit 46. The contact elements 82, 84 are electrically connected to the electrical energy supply 44 in the form of a power pack by means of connecting lines.

figure 4 shows the door leaf 14 and the guide rail 40 in a partial sectional view, with the plug-in unit 46 being inserted into the guide rail 40 . The plug-in unit 46 rests on the wall sections 62, 64 of the guide rail 40. The electrical contact elements 82, 84 are in electrical contact with the electrical conductor elements 66, 68 (not provided with reference numbers for the sake of clarity). This contact is made when the plug-in unit 46 is pushed in.

The figures 5 , 7a , 7b and 8th show the guide slider 42. The guide slider 42 has first contact elements 86, 88 and second contact elements 90, 92 electrically connected thereto (cf. Figures 7a and b ). The first contact elements 86, 88 are arranged on a different body side of the guide slider 42 than the second contact elements 90, 92.

If the guide slider 42 is inserted into the guide rail 40, the first contact elements 86, 88 are in contact with the conductor elements 66, 68 (cf. Fig.8 ). The second contact elements 90, 92 are in contact with contact surfaces 94, 96 arranged on the wing side (cf. Fig.5 and 6 ), which are electrically or electronically connected to at least one of the wing-side consumers, e.g. the controller 52.

The second contact elements 90, 92 extend away from the guide slider 42 along a direction of extension 98 (cf. Fig.7a ), ie in the installed state towards the door leaf 14 (cf. Fig.5 ). The second contact elements 90, 92 are elastic and deformable, for example compressible, along the direction of extent 98 in order to compensate for a distance between the guide slider 42 and contact surfaces 94, 96 along the direction of extent 98.

The first contact elements 86, 88 are each designed as convex metal strips (cf. Figures 7a and b ). As a result, the contact elements 86, 88 can compensate for manufacturing or assembly tolerances and reliably contact the conductor elements 66, 68 (cf. Fig.8 ).

The second contact elements 90, 92 are each designed as metal strips shaped into a ring or into an ellipse (cf. Figures 7a and b ).

The first contact elements 86, 88 and the second contact elements 90, 92 are each electrically connected to one another by means of a contact block 100, 102, with a first contact element 86, 88 and a second contact element 90, 92 being screwed to the contact block 100, 102. As a result, the contact elements 86, 88, 90, 92 are mechanically and electrically connected. By arranging the contact blocks 100, 102 in corresponding recesses (unnumbered) in the guide slide 42, the contact blocks 100, 102 and the contact elements 86, 88, 90, 92 are secured to the guide slide in the connected state.

The first contact elements 86, 88 are each screwed to the contact block 100, 102 at one end (fixing section) by means of a screw. The first contact elements 86, 88 each extend from this end to a free end. A depression for the fastening section of the first contact element 86, 88 is formed on the contact block 100, 102 (cf. Fig.7b ). This prevents the first contact elements 86, 88 from twisting relative to the contact block 100, 102.

The second contact elements 90, 92 are each interrupted at one point, with outwardly protruding lugs 104, 106 being formed at the interruption (cf. Fig.7b ).

For assembly, the lugs 104, 106 are inserted into an opening on the guide slider 42 and lie against the contact block 100, 102. The second holding elements 90, 92 are each screwed to the contact block 100, 102 by means of a retaining plate 108, 110 covering the interruption and a screw 112, 114 passed through the interruption.

The first contact elements 86, 88 are offset from one another along the central longitudinal direction 116 of the guide slider 42 (displacement direction 116). The second contact elements 90, 92 are offset from one another along the central longitudinal direction 116 of the guide slider 42.

Concave recesses 118, 120 are formed in the guide slider 42 and extend along the central longitudinal direction 116, in each of which a second contact element 90, 92 is seated (cf. Figures 7a and b ). The second contact elements 90, 92 are arranged in sections in the recess 118, 120 and extend away from the guide slider 42. The recesses 118, 120 are arranged offset to one another along the central longitudinal direction 116 of the guide slider 42.

A drive element 122 in the form of a gear wheel is arranged in the guide slider 42 and drives a driven element 124 in the form of a toothed belt fastened to the frame 12 (cf. Fig.5 ). The toothed belt 124 has open ends and is fixed to the frame 12 (not shown).

The gear wheel 122 has a shaft section 126 connected thereto in a torque-proof manner, via which the gear wheel 122 can be coupled to the electric drive unit 50 . Deflection rollers 128, 130, bearing journals 132, 134 for the deflection rollers, a corresponding recess 136 for receiving gear wheel 122 and deflection rollers 128, 130 and a retaining plate 138 are also provided on the guide slider 42.

figure 6 shows the contacting unit 48 on its own. In the mounted state, the contacting unit 48 is attached to the narrow side of the door leaf 14 (upper side of the leaf) facing the guide rail 40 (cf. Fig.5 ).

The contacting unit 48 has an insulating carrier plate 140 and two contact plates 142, 144 fastened to the carrier plate 140 (cf. Fig.6 ). The contact surfaces 94 , 96 are each formed by a surface of the contact plates 142 , 144 which faces the guide rail 40 . The contact plates 142, 144 are arranged separately on the carrier plate 140 and are separated from one another by a web 146 projecting from the carrier plate 140. The carrier plate 140 has fastening holes 148, 150 and can be fastened to the door leaf 14 by means of screws.

On the support plate 140, a pocket 152, 154 is formed for each contact plate 142, 144, which accommodates the contact plate in each case at least in sections, with each Pocket one or more locking lugs 156, 158 are formed so that the contact plate 142, 144 can be attached to the support plate 140 by means of a locking connection. Each contact plate has a connecting lug 147, 149 for electrical contacting.

The control 52 arranged on the wing side is provided as a further consumer (cf. Fig.1 ), which has a data transmission device, wherein the electrical energy supply 44 also has a data transmission device in the form of a power pack, the data transmission devices being designed to send and receive data signals modulated onto electrical lines and connected to one another via electrical lines, as described above.

The electric drive unit 50 arranged on the leaf side for moving the door leaf 14 is provided as a further consumer (cf. Fig.1 , 5 and 8th ). The electric drive unit 50 drives the gear wheel 122 arranged in the guide slider 42 . The electric drive unit 50 is electrically or electronically coupled to the controller 52 and is controlled by the controller 52 .

The drive unit 50 has an electric motor 160, which can optionally be followed by a reduction gear 162 (reduction gear 162 between the electric motor 160 and the gear wheel 122).

A clutch device 164, which can be actuated manually in the example, is provided between electric drive unit 50 and gear wheel 122, by means of which a power flow can be established between drive unit 50 and gear wheel 122 and a power flow between drive unit 50 and gear wheel 122 can be interrupted. By bringing the coupling device 164 into the uncoupled position (cf. Fig.8 ), the door leaf 14 can be easily inserted into or removed from the frame 12.

The accumulator 54 arranged on the wing side is provided for the energy supply of electrical energy consumers arranged on the wing side (cf. Fig.1 ). The accumulator 54 is charged by the power pack 44 independently of the sliding position of the door leaf 14 . The accumulator 54 supplies the controller 52 and the electric drive unit 50 with electrical energy.
