Description

AUTOMATIC SLIDING SASH ARRANGEMENT The present invention relates to an automatic sliding sash arrangement of a door or a window, comprising at least one lift-and-slide sash, which can be driven by means of an, in particular, electrical drive device which can be actuated by an electronic control device. Automatic sliding sash arrangements of the aforementioned type are generally known from European patent application EP 3 078 796 A1. The electromotive drive of such automatic sliding sash arrangements not only brings about the lifting of the lift-and-slide sash, but also the subsequent displacement of same, as a result of which the actuation of the lift-and-slide sash is simplified.

Sliding doors are likewise frequently used on cruise ships as balcony doors or windows owing to the required sealing to the side of the ship and for reasons of space. The door or window is sealed to the side of the ship by lowering and pressing of the door or the window, said pressing effected by the lowering. The corresponding movement generally occurs mechanically via a handle or the like. S The previously known sliding sash arrangements are relatively complex and 5 correspondingly costly. When used on cruise ships, there is also the problem o 25 that the outer side of the sliding sash arrangement facing the sea is exposed = to weather to a greater degree, so weather-sensitive drive components of an 3 automatic sliding sash arrangement are exposed to greater wear. S The aim of the invention is to disclose an automatic sliding sash arrangement N 30 of the aforementioned type which guarantees reliable operation with a structure kept as simple and correspondingly cost-effective as possible in particular for the critical weather conditions which, for example, cruise ships are exposed to.

This aim is achieved, according to the invention, by an automatic sliding sash arrangement comprising the features of claim 1. Preferred embodiments of the automatic sliding sash arrangement according to the invention, result from the dependent claims, the present description and the drawing.

According to the invention, the automatic sliding sash arrangement of a door or a window, comprises at least one lift-and-slide sash, which can be driven by means of an, in particular, electrical drive device which can be actuated by an electronic control device. Here, the drive device comprises a drive for raising and lowering the lift-and-slide sash and a drive coupled with the lift- and-slide sash for displacing the raised lift-and-slide sash along a rail, wherein the electronic control device and the drive for displacing the lift-and- slide sash are arranged on the inner side of the sliding sash arrangement, which inner side faces the interior of a space provided with the sliding sash arrangement.

Owing to said design, with a structure kept as simple and correspondingly _ cost-effective as possible, reliable operation is guaranteed also in the case of O critical weather conditions. The lift-and-slide sash is raised by means of the 5 drive for raising and lowering the lift-and-slide sash. The lift-and-slide sash o 25 can then be displaced along the rail. The lift-and-slide sash is displaced by = the drive for displacing the lift-and-slide sash, which drive can be actuated by 3 the electronic control device, wherein said control device and drive are O arranged on the inner side of the sliding sash arrangement, said inner side = facing the interior of a space provided with the sliding sash arrangement. The particularly vulnerable drive components are not exposed to weather in that the electronic control device and the drive for displacing the lift-and-slide sash are arranged on the inner side of the sliding sash arrangement.

The automatic sliding sash arrangement according to the invention, can thus be used, in particular, as a balcony door or balcony window of a cruise ship or the like.

Preferably, the electronic control device and the drive for displacing the Iift- and-slide sash are installed on a common module carrier to form an inside modular unit.

In this way, not only is the assembly simplified, but an easy retrospective conversion or retrofitting is also made possible.

The inside modular unit can also comprise a power supply unit, accumulator, distribution box and/or the like mounted on the common module carrier.

The components installed on the module carrier, in addition to the electronic control device and the drive for displacing the lift-and-slide sash, are also not exposed to weather and thus protected in that the corresponding modular unit is arranged on the inner side of the sliding sash arrangement.

The drive for displacing the lift-and-slide sash can be coupled to the lift-and- slide sash advantageously via a force transmission element arranged on the outer side of the sliding sash arrangement.

S In this regard, the force transmission element can comprise, for example, a 5 traction element and, in particular, a toothed belt or the like, which can be o 25 guided on the one side about a drive roller that can be driven via the drive for = displacing the lift-and-slide sash and on the other side about a deflection 3 roller.

The force transmission element and the traction element or toothed O belt is less vulnerable to weather, so such a force transmission element can = be arranged on the outer side of the sliding sash arrangement.

However, in N 30 order to protect said components from weather effects, the force transmission element and the traction element or toothed belt with the associated drive roller and deflection roller can be provided with a cover on the outer side of the sliding sash arrangement.

The drive for displacing the lift-and-slide sash can be preferably coupled to the force transmission element via a coupling. It is also beneficial, in particular, if the drive for raising or lowering the lift-and- slide sash is arranged or integrated in the sash profile of the lift-and-slide sash.

The drive for raising and lowering the lift-and-slide sash can, for example, comprise a spindle drive.

Preferably, the lift-and-slide sash can be displaced via running rollers along the rail. The lift-and-slide sash can, in particular, be provided with roller carriages, on which the running rollers are arranged.

In accordance with a preferred practical embodiment of the automatic sliding sash arrangement according to the invention, each of the running rollers and roller carriages is provided with a tilt mechanism.

O It is particularly beneficial if the connection between the force transmission 5 element and the lift-and-slide sash is configured in a displaceable, in S 25 — particular articulated, manner.

I = < The lift-and-slide sash is preferably coupled with the force transmission O element via at least one driver which can be displaced in a linear manner by = the force transmission element. The force transmission element and the

N driver can, in particular, be coupled with the lift-and-slide sash via a swivel arm. In this regard, at least one running roller associated with the lift-and- slide sash can be mounted, in particular, on the swivel arm. In order to ensure that the drive for raising and lowering the lift-and-slide 5 sash is powered over the entire adjust path of the lift-and-slide sash, said drive can be electrically powered via an energy chain, a spiral cable and/or the like. The electronic control device can comprise, for example, a button or the like, — via which a raising or displacing of the lift-and-slide sash can be triggered. Same can also comprise a contact switch or the like, via which the drive for displacing the lift-and-slide sash, said drive being coupled with the lift-and- slide sash via the force transmission element, can be activated as soon as the lift-and-slide sash has been raised.

As soon as an operator actuates the button, the lift-and-slide sash is immediately raised and brought into the position for displacement. The drive coupled with the lift-and-slide sash via the force transmission element receives the command to displace the lift-and-slide sash via the contact switch or the like. _ In certain cases, it is advantageous if the electronic control device comprises O a program switch or the like, via which the drive device can optionally be 5 actuated to transfer the raised lift-and-slide sash into a airing position or into o 25 the complete open position. j < According to a preferred practical embodiment of the sliding sash O arrangement according to the invention, the drive device can be actuated by = the control device, in particular by a corresponding programming of said control device, such that with an actuation of a button or the like associated with the control device, the drive for raising and lowering the lift-and-slide sash or the spindle drive is started and after the lift-and-slide sash is raised both a displacing of the lift-and-slide sash by the drive for displacing the lift- and-slide sash over any open region and an airing function are made possible, in which the lift-and-slide sash remains raised in a desired open position. The sliding sash arrangement can be started accordingly, for example, by an inner or outer button. In this regard, the lift-and-slide sash remains raised into a motor brake operation for an airing function, advantageously by an actuation of the drive provided to raise and lower the lift-and-slide sash. The loads of the various components of the sliding sash arrangement, such as, among others, those of the door sealings, the spindle motor and the like, are reduced and a break- in is made more difficult in that the lift-and-slide sash is held electronically by the motor brake for the airing function. Furthermore, further convenience features are also conceivable depending on the customer requirements. The especially linearly displaceable driver, advantageously, has such a shape that same is arranged constantly freely across the whole path between _ the contours of the lift-and-slide sash, a frame associated with same, the rail O and/or the like irrespective of whether the lift-and-slide sash assumes a 5 raised or lowered position. o 25 = The traction element or toothed belt provided as a force transmission 3 element can be fixed, advantageously, in a carriage at the two ends, wherein O the two carriages can be adjusted relative to one another via a tensioning = screw or the like in order to tension the traction element or the toothed belt.

N

The two carriages can be moved towards each other in particular by a tensioning screw comprising a right-hand and a left-hand thread.

In this way, the traction element or the toothed belt can be closed at a position accessible for installation and tensioned by adjusting the carriages accordingly via the tensioning screw.

The position of the two carriages relative to the driver can be secured, for example, via screws.

After the lift-and-slide sash has been raised, it can also be predetermined — whether the lift-and-slide sash of the door or of the window is to be always fully opened or whether an airing position is wanted.

The corresponding choice can be made, for example, via the program switch.

The automatic sliding sash arrangement according to the invention, can be used among other things, for a balcony door or for a balcony window and in particular for a balcony door or for a balcony window of a cruise ship.

The more sensitive drive components are not exposed to weather and are thus protected in that the electronic control device and the drive for displacing the lift-and-slide sash are arranged on the inner side of the sliding sash arrangement.

Long-lasting and reliable operation of the sliding sash arrangement is thus also ensured when the sliding sash arrangement is used _ on a cruise ship.

Since the components to be arranged on the inner side of O the sliding sash arrangement are installed on a module carrier, same can be 5 installed as a unit, with which the assembly is substantially simplified and an o 25 easy retrofitting or conversion is also made possible.

When used on a cruise = ship, the sensitive components face away from the sea side and are thus 3 installed, for example, on the fire cladding of the door system in a protective O manner.

Since the lift-and-slide sash is not raised or lowered directly, but by = a tilt motion of the roller carriage support member, the drive system provided to displace the lift-and-slide sash can be more easily installed on the inner side of the sliding sash arrangement. Subsequent conversions can be carried out without any greater structural changes. The relevant components on the inner side of the sliding sash arrangement can be installed directly on the door or window system attachment via the module carrier. No additional attachment points are thus required. In order to be able to compensate for tolerances in the entire door or window element, the coupling provided between the drive for displacing the lift-and-slide sash and the force transmission element can be adjusted accordingly. Corresponding safety devices can be provided to secure the sliding plane. The drive device can be actuated via said buttons and/or via remote control or the like. Since the sensitive and vulnerable components are installed on the inner side of the sliding sash arrangement, said components are also protected from external damage and/or tampering.

The invention is explained in more detail below on the basis of an embodiment with reference to the drawing, in which the following are shown: fig. 1 a schematic front view of an exemplary embodiment of an automatic sliding sash arrangement of a door or a window, according to the invention; _ fig. 2 a schematic side view of the top part of the sliding sash O arrangement according to fig. 1 with lowered lift-and- 5 slide sash; o 25 = fig. 3 a schematic side view of the top part of the sliding sash a < arrangement according to fig. 1 with raised lift-and-slide

O i, sash; and

N fig. 4 a schematic diagram of an exemplary driver comprising the force transmission element which is attached to same and has a toothed belt and comprising a tensioning device associated with the toothed belt.

Figures 1 to 4 schematically show an exemplary embodiment, according to the invention, of an automatic sliding sash arrangement 10 of a door or of a window, comprising at least one lift-and-slide sash 12 and at least one adjacent fixed sash 14.

The lift-and-slide sash 12 can be driven by means of an, in particular, electrical drive device 18 which can be actuated by an electronic control device 16.

The, in particular, electrical drive device 18 comprises a drive 184 for raising and lowering the lift-and-slide sash 12 and a drive 182, which is coupled with the lift-and-slide sash 12, for displacing the raised lift-and-slide sash 12 along arail 22.

The electronic control device 16 and the drive 18; for displacing the lift-and- slide sash 12 are arranged on the inner side 20 of the sliding sash _ arrangement 10, said inner side facing the interior of a space provided with O the sliding sash arrangement 10. > S 25 In this regard, the electronic control unit 16 and the drive 18; for displacing = the lift-and-slide sash 12 are installed on a common module carrier 36 (cf. fig. 3 3) to form an inside modular unit. In addition, the inside modular unit, for O example, can also comprise a power supply unit, accumulator, distribution = box and/or the like mounted on the common module carrier 36.

N

The drive 182 for displacing the lift-and-slide sash 12 can be coupled with the lift-and-slide sash 12 via a force transmission element 26 arranged in particular on the outer side 24 of the sliding sash arrangement 10. In this regard, the force transmission element 26 can comprise, for example, a traction element and in particular a toothed belt or the like, which can be guided on the one side about a drive roller 28 that can be driven via the drive 182 for displacing the lift-and-slide sash 12 and on the other side about a deflection roller 30 (cf. fig. 1). The force transmission element 26 and the traction element or toothed belt with the associated drive roller 28 and deflection roller 30 can be provided with a cover on the outer side 24 of the sliding sash arrangement 10. The drive 182 can be coupled via a coupling 32 with the force transmission element 26 for displacing the lift-and-slide sash 12. The drive 184 for raising or lowering the lift-and-slide sash 12 can be arranged in the sash profile of the lift-and-slide sash 12. The drive 181 for raising and lowering the lift-and-slide sash 12 can, for example, comprise a spindle drive. _ As is clear in particular on the basis of fig. 1, the lift-and-slide sash 12 can be O displaced via running rollers 34 along the rail 22. In this regard, the lift-and- 5 slide sash 12 can in particular be provided with roller carriages 38, on which o 25 the running rollers 34 are arranged. j < The running rollers 34 and roller carriages 38 can each be provided with a tilt O mechanism (cf. fig. 2 and 3). The connection between the force transmission = element 26 and the lift-and-slide sash 12 is configured in a displaceable, in N 30 particular articulated, manner.

The lift-and-slide sash 12 can be coupled with the force transmission element 26 via at least one driver 42 (cf. fig. 1) which can be displaced in a linear manner by the force transmission element 26. In this regard, a running roller 34 associated with the lift-and-slide sash 12 can be mounted, for example, on the swivel arm 44. In order to ensure the energy supply, over the whole path of the lift-and-slide sash 12, to the drive 181 being used to raise and lower the lift-and-slide sash 12, the drive 181 can be provided with electrical energy via an energy chain 40 (cf. fig. 1), a spiral cable or the like. The electronic control device 16 can comprise a button or the like, via which a raising or displacing of the lift-and-slide sash 12 can be triggered.

In addition, the electronic control device 16 can also comprise a contact switch or the like, via which the drive 182 for displacing the lift-and-slide sash 12, said drive being coupled with the lift-and-slide sash 12 via the force transmission element 26, can be activated as soon as the lift-and-slide sash 12 has been raised. _ In addition, the electronic control device 16 can in particular comprise a O program switch or the like, via which the drive device 18 can optionally be 5 actuated in order to transfer the raised lift-and-slide sash 12 into an airing o 25 — position or into the completely open position. j < The lift-and-slide sash 12 is raised by means of the drive 184. The lift-and- O slide sash 12 can be displaced by means of the running roller 34 and roller = carriages 38. The lift-and-slide sash 12 is displaced by the drive 182 coupled N 30 with the lift-and-slide sash 12 via the force transmission element 26 and/or the traction element or toothed belt. The force transmission element 26 and the lift-and-slide sash 12 are connected via a displaceable and pivotable coupling.

After the button is actuated by an operator, the lift-and-slide sash 12 is immediately raised and brought into a position for displacement. Via the contact switch, the drive 182 coupled with the lift-and-slide sash 12 via the force transmission element 26 receives the command to displace the lift-and- slide sash 12 along the rail 22. It can now be decided whether the lift-and- slide sash 12 is to assume an airing position or move into the completely open position. A remote control, for example, is also conceivable. As already mentioned, a traction element, in particular a toothed belt or the like, for example, can be provided as a force transmission element 26. In principle, other force transmission elements are also conceivable though. The automatic sliding sash arrangement 10 according to the invention, can be used, among other things, for a balcony door or for a balcony window and also, in particular, for a balcony door or for a balcony window of a cruise ship. The sensitive drive components lie in the protected region, so are not exposed to weather, in that same are arranged on the inner side of the _ sliding sash arrangement. With the arrangement of the sensitive drive O components on the side facing away from the sea side, same can, for 5 example, be installed on the fire cladding of the door system in a protected o 25 manner. Because the lift-and-slide sash 12 is not raised and lowered directly, = but by a tilt motion of the roller carriage support member, the drive system for 3 displacing the lift-and-slide sash 12 can be more easily installed on the side O facing away from the lift-and-slide sash 12 or on the inner side of the sliding = sash arrangement 10. The sliding sash arrangement according to the N 30 invention, thus also guarantees reliable operation in particular under critical weather conditions, to which, for example, cruise ships are subjected.

Subsequent conversion is also possible without major structural changes to the door system.

In order to be able to compensate for tolerances in the entire door or window element, the coupling 32 provided between the drive 18 for displacing the lift-and-slide sash 12 and the force transmission element 26 can be adjusted accordingly.

The drive device 18 can be actuated by a correspondingly programmed control device 16 such that with an actuation of a button or the like associated with the control device 16, the drive 184 for raising and lowering the lift-and-slide sash 12 or the spindle drive is started and after the lift-and- slide sash 12 is raised both a displacing of the lift-and-slide sash 12 by the drive 182 for displacing the lift-and-slide sash 12 over any open region and an airing function are made possible, in which the lift-and-slide sash 12 remains raised in a desired open position.

The sliding sash arrangement 10 can be started accordingly, for example, by an inner or outer button.

In this regard, the lift-and-slide sash 12 can remain raised into a motor brake operation for an airing function, for example by an actuation of the drive 181 provided to raise and lower the lift-and-slide sash 12. The loads of the various components of the sliding sash arrangement, such as, among others, _ those of the door sealings, the spindle motor and the like, are reduced and a O break-in is made more difficult in that the lift-and-slide sash 12 is held 5 electronically by such a motor brake for the airing function. o 25 = Furthermore, further convenience features are also conceivable depending 3 on the customer requirements.

S Fig. 4, in particular, indicates that the especially linearly displaceable driver 42 can have such a shape that same is arranged constantly freely across the whole path between the contours of the lift-and-slide sash 12, a frame associated with same, the rail 22 and/or the like irrespective of whether the lift-and-slide sash 12 assumes a raised or lowered position. The traction element or toothed belt provided as a force transmission element 26 can be fixed, advantageously, in a carriage 48 at two ends 26', 26", wherein the two carriages 48 can be adjusted relative to one another via a tensioning screw 58 or the like in order to tension the traction element or the toothed belt 26. The two carriages 48 can be moved towards each other, for example, by a tensioning screw 58 comprising a right-hand and a left- hand thread. In this way, the traction element or the toothed belt 26 can be closed at a position accessible for installation and tensioned by adjusting the carriages 48 accordingly via the tensioning screw 58. The position of the two carriages 48 relative to the driver 42 can be secured, for example, via screws 52. When used on a cruise ship, the required sealing to the side of the ship 46 (cf. fig. 2 and 3) can be effected by lowering and pressing the lift-and-slide sash 12, said pressing effected by the lowering.
