Description

The present invention relates to a lift-and-slide door system with a frame, a sliding door arranged in the frame, which can be moved along a running rail between a closed position and an open position, the sliding door being movable via a lift drive between a lowered and a raised position and in a raised position can be moved manually or via a displacement drive along the running rail, the lifting drive on the sliding door in the closed position being connected via a contact element of the sliding door to an electrical power supply via a supply contact, and a method for mounting a sliding door on a frame.

the DE 20 2019 002 391 discloses a sliding system in which a lifting-sliding sash is held in a frame so as to be movable. The lift and slide sash can be moved from a lowered locking position to a raised position via an operating element. A drive with a drive roller, which is arranged on the top of the lever sliding door, can then be moved into an open position via a carriage along a running rail. For power supply, a control line is connected in a loop to the drive on the lift and slide sash and can thus supply the drive motor with power in any position. It is true that the sash can be supplied with power regardless of its position, but the assembly of the loop-shaped control cable is complex and also prone to errors due to the constant stress when the sliding sash moves.

It is therefore the object of the present invention to create a lift-and-slide door system in which a reliable power supply for the electrical drives for moving the sliding door is guaranteed. In addition, a simple assembly of the sliding door on a frame should be made possible.

This object is achieved with a lift-and-slide door system with the features of claim 1 and a method with the features of claim 11.

In the lift-and-slide door system according to the invention, a lift drive on the sliding door is supplied with electrical power, in which a contact element of the sliding door is connected to a supply contact for an electrical power supply when the sliding door is in a closed position, the contact element when the sliding door is moved from the closed position in the opening direction from the supply contact is spaced and the power supply to the linear actuator is interrupted. As a result, the power supply can be made via permanently installed lines on the frame, which conduct the current to the supply contact, which supplies the lifting drive with current in the closed position. When the sliding door is in an open position, it remains in the raised position together with the lifting drive. This then enables the sliding door to be moved horizontally either manually or via an electric drive. Only when the sliding door is in the closed position again or shortly before it is electrical contact made between the supply contact on the frame and the contact element on the sliding door, so that the lifting drive can lower the sliding door again in order to fix the sliding door in the closed position and optionally also to be locked.

The supply contact is preferably fixed to a frame profile of the window frame. For this purpose, a recess can be formed on a vertical frame profile, that is to say a post, on which the supply contact is fixed. Furthermore, the contact element can be fixed to a profile of the sliding door that is at the front in the closing direction. The contact element can then be mounted opposite the supply contact and establishes an electrical connection to the power supply only in the closed position or a few millimeters beforehand. As a result, the contact element and the supply contact are not visible from the outside in the closed position, since the two are arranged on a facing end face of a profile of the window frame and a profile of the sliding door. Optionally, the supply contact and the contact element can be provided on an upper frame profile of the window frame and the sliding door.

In a preferred embodiment, a connection is arranged on the sliding door which can be contacted by a contact plug of an emergency power supply in order to supply the lifting drive with power, in particular in the low-voltage range. As a result, the lift drive can be supplied with power via an emergency power supply both during assembly and when servicing, in order to raise or lower the sliding door. The connection is preferably designed as a contact socket which can be brought into engagement with the contact plug. The emergency power supply can, for example, have a switch in order to be able to control the lifting drive via the connection in order to control the raising or lowering of the sliding sash.

So that the connection is easily accessible, it can be arranged on a front or rear side of the sliding door, that is to say not on a narrow side of the sliding door that is concealed in the closed position. Rather, the connection can preferably be connected to be arranged on the inside of the sliding door behind a cover that is removed in a service case or for assembly in order to connect the lift drive to the emergency power supply.

To establish an electrical connection between the contact element and the supply contact, one of the two contacts can comprise a plunger pretensioned by a spring, and the other contact can comprise a contact plate, for example. A reliable electrical contact can thereby be ensured, which, for example, as a sliding contact during the lifting movement, maintains the electrical connection. Optionally, one of the two contacts can also be designed as a spring contact, in particular as a metallic spring bar. The contact plate can optionally also be resiliently mounted in order to keep the mechanical load low during electrical contact.

An actuating element, which can be moved by a tool, for rotating a gear for raising and lowering the sliding sash is preferably provided on the sliding sash. As a result, if the lifting drive fails, the sliding sash can be moved in the vertical direction mechanically by a tool which is brought into engagement with the actuating element in order to actuate a drive rod via a transmission to raise or lower the sliding sash.

In the method according to the invention for mounting a sliding door on a window frame, the sliding door with the carriage is first set up on a running rail within the window frame. Then an emergency power supply is connected with a contact plug to a connection on the sliding door for a lift drive in order to then supply the lift drive with power via the emergency power supply and lift the sliding door. In the raised position, the sliding door can then be moved into a closed position on the window frame in order to establish an electrical connection between a contact element on the sliding door and a supply contact on the window frame. In this position, the linear actuator can then be supplied with power via the supply contact. The emergency power supply is then removed from the sliding door, the connection for contacting preferably being closed by a cover so that the connection is protected from environmental influences.

Optionally, the cover can also be used to cover access to a mechanical actuating element with which the sliding sash is raised or lowered using a tool.

Lifting the sliding door 3 Via the fitting arrangement, you can optionally use the electric lifting drive 5 take place, which is shown only schematically and can have a drive part that is connected to a part of the transmission 7th is engaged. Optionally, an engagement for a tool can also be provided on the gear so that the sliding door is opened when the tool is applied 3 can also be raised or lowered mechanically.

In 3 is the lift and slide door system 1 in a slightly open position of the sliding door 3 shown in section. It can be seen that on the frame 2 on a vertical profile 20th a supply contact 16 with two pins attached to a holder 15th are fixed. The pins of the supply contact 16 are over lines 17th connected to an electrical power supply, preferably in the low current range, for example with 24 volts. The holder 15th is in a recess on a bar 21 added that to the profile 20th on the one to the sliding door 3 turned side is set. The pins of the supply contact 16 can be biased into the protruding position by a spring and can be pressed in the closing direction when contact is made.

The sliding door 3 comprises a frame with a vertical frame profile 30th , which is arranged in the closing direction at the front. On this frame profile 30th is a contact element 32 arranged in the form of a metallic contact plate which comprises two contact areas which each engage with one of the pins of the supply contact 16 can get. The two areas for contacting the contact element 32 are electrically isolated from each other. The contact element 32 is about fasteners 33 on a ledge 31 held on to the frame profile 30th is fixed on a front side in the closing direction.

Will the sliding door 3 moved in the closing direction, the pins of the supply contact arrive 16 in contact with a respective area on the contact element 32 to the one on the sliding door 3 arranged lifting drive 5 to be supplied with electricity. In the closed position, the power supply can be used to lower and raise the sliding door 3 take place. The sliding door can be in the open position 3 in a raised position from the vertical profile 20th of the frame 2 remove so that the electrical power supply between the supply contact 16 and the contact element 32 is interrupted. The lifting drive 5 holds the sliding door 3 despite interruption of the power supply in the raised position so that the sliding door 3 manually or via the traversing drive 14th can be moved.

In 4th is the one in the 1 and 2 cover shown schematically 6th with the rosette 25th shown on an inner side of the sliding door 3 is fixed, preferably on the frame profile 30th . The rosette 25th includes an opening 26th to which a connector 28 is arranged in the form of a contact socket.

The connection 28 is via a power line, not shown, to the lifting drive 5 connected so that the linear actuator 5 optionally via the supply contact 16 or the connection 28 can be powered.

On the rosette 25th is another opening 27 provided on which a support disc 22nd and a sleeve 23 are mounted, being on or in the sleeve 23 a rotatable actuator 24 , in particular a ring gear, which is in engagement with the transmission 7th to raise or lower the sliding door 3 stands. Using a tool (not shown), for example a hexagon wrench, the actuating element 24 be rotated, allowing manual raising and lowering of the sliding door 3 remains possible if the lifting drive 5 is defective.

With the lift-and-slide door system 1 the sliding door is installed 3 not in a closed position, i.e. directly on the vertical profile 20th , but in a middle opening position. The sliding door is therefore used for assembly 3 on the track 12th placed and coupled in the upper area with guide elements on a guide rail, not shown, so that the sliding door 3 along the track 12th and the guide rail can be moved in the frame 2 is held. The sliding door 3 is still in the lowered position and can therefore not be moved.

An in 5 Emergency power supply shown 40 used. The emergency power supply 40 includes a housing 41 with a switch 42 that over one line 44 with a contact plug 43 connected is. The contact plug 43 can in the port 28 be plugged in or clipped on. The case 41 is via another line 45 with a plug 46 connected, which can be connected to a battery or an electrical power supply. Via the emergency power supply 40 can thus provide an electrical power supply via the contact plug 43 and the connection 28 for the lifting drive 5 to be provided. This allows when assembling the sliding door 3 the lifting drive 5 operated to the sliding door 3 raise so this smoothly along the track 12th can be proceeded.

When assembling the sliding door 3 then moved to a closed position in which the supply contact 16 the contact element 32 contacted and supplied with power. Then the emergency power supply can 40 from the sliding door 3 must be removed as the linear actuator 5 via the supply contact 16 can be raised and lowered in the closed position. By using the emergency power supply 40 is a manual raising or lowering of the sliding door 3 no longer necessary, which makes assembly easier.

If the linear actuator 5 fails due to a defect, the sliding door can be raised or lowered if necessary 3 take place via a tool that is in engagement with the actuating element 24 is brought to the gearbox 7th to drive.

The supply contact is located in the illustrated embodiment 16 on a vertical profile 20th of the frame 2 and the contact element on a vertical frame profile 30th . It is of course also possible to use the supply contact 16 and the contact element 32 in the upper area of the sliding door 3 and a horizontal profile of the frame 2 to be provided. In addition, the design of the supply contact 16 and the contact element 32 can be varied in order to enable contact with as little wear as possible in the closed position.
