EP3241971B1 - Sliding window device for building - Google Patents

Description

The invention relates to a building sliding window device according to the preamble of claim 1.

Sliding windows for buildings are known which can be opened and closed by moving them. Such sliding windows often comprise two windows that can be moved independently of one another and can be moved by hand.

A disadvantage of such windows is that they are often cumbersome to use and tend to jam. Furthermore, the window opening can be released by a maximum of half by dividing the two.

From the US 1,935,559 A. is known a sliding building window device according to the preamble of claim 1 with a, arranged between two guide rails window, the window being driven by a motor.

From the DE 20 59 505 A1 a window with a built-in cleaning device is known. The window has a closed housing in which the cleaning device and a motor are arranged. The sliding window is moved by a chain drive that the motor drives.

From the GB 726 734 A. a sliding window is known which has no electric drive. Instead, the window is connected in an upper area with two sprung pull cables to counteract the weight of the window. The sliding window has on the side, by means of a knob, manually movable hooks which engage in the lateral guide rails of the window opening and can thereby hold the window in the window opening or press it against a seal.

The object of the invention is therefore to provide a sliding window device of the type mentioned at the beginning, with which the disadvantages mentioned can be avoided, which are simple to use and can expose a larger part of a window opening.

According to the invention this is achieved by the features of claim 1.

This has the advantage that the window of the building sliding window device can be operated easily and reliably, manual handling of the window being eliminated. The window can be moved into a separate receiving space by the electric drive device, since it is no longer necessary for the user to have to handle the window directly, or for the window to be manipulated. This means that the division into two can be omitted, which means that more than half of the window opening can be released. As a result, the window can give a feeling of space that is similar to that of a casement window, but still require little space, such as a sliding window. Furthermore, the electric drive device improves the security of the window, be it by avoiding an unintentionally sliding window and associated injuries or by improving burglary protection. Furthermore, the electric drive device enables simple operation by the user, or can also be operated without any direct presence of the user, be it via the user by means of a remote control or mobile phone, or via a programmable building control system. Furthermore, the building sliding window device can be more easily integrated into an alarm system.

The subclaims relate to further advantageous refinements of the invention.

Reference is hereby expressly made to the wording of the patent claims, as a result of which the claims are inserted at this point by reference into the description and are considered to be reproduced verbatim.

A building sliding window device 1 is a device with a sliding window 2 for a building 9. To move the window 2, the building sliding window device 1 has two laterally arranged running guide rails 3, the guide rails 3 guiding a movement of the window 2 along the guide rails 3.

It is provided that the building sliding window device 1 is an electric drive device 4 for displaceable displacement of the window 2 relative to the Guide rails 3 has. An electric drive device 4 is an electrically operated device for the definable displacement of the window 2 along the guide rails 3. The drive device 4 can in particular have a motor 7, the motor 7 being designed as an electric motor. Furthermore, the drive device 4 has means for causing the window 2 to be displaced by the movement of the motor 7.

This results in the advantage that the window 2 of the sliding window device 1 can be operated simply and reliably, manual manipulation of the window 2 being eliminated. The window 2 can be moved into a separate receiving space 10 by the electric drive device 4, since it is no longer necessary for the user to have to handle the window 2 directly, or for the window 2 to be manipulated. As a result, the division into two can be omitted, as a result of which more than half of the window opening 6 can be released. As a result, the window 2 can give a similarly good feeling of space as a casement window, but still require a small amount of space, such as a sliding window. Furthermore, the electric drive device 4 improves the security of the window 2, be it by avoiding an unintentionally sliding window 2 and associated injuries or by improving the burglar protection. Furthermore, the electric drive device 4 enables simple operation by the user, or can also be operated entirely without direct presence of the user, be it via the user by means of a remote control or a mobile phone, or via a programmable building control.

Alternatively, the building sliding window device 1 can have a plurality of windows 2 which can be moved independently of one another.

It can particularly preferably be provided that the window 2 is essentially vertically displaceable along the guide rails 3. In this context, essentially vertical means in particular a deviation of up to 15 ° from the vertical when the building sliding window device 1 is in the installed state. Advantage of the essentially vertically displaceable window 2 is that an essentially vertically displaceable window 2 with an electric drive device 4 is used the design of a room essentially has the same space requirement as a conventional casement window, since the space to the side of the window opening 6 is not required for the function of the window as in the case of a sliding window 2. This makes it possible for the sliding window device 1 also in corners of a room or use several building sliding window device 1 side by side z, with no restrictions in the arrangement of the building sliding window device 1. As a result, the space available for the outer wall 13 for windows 2 can be optimally used and restrictions in the arrangement of the windows 2 for the interior design can be avoided. Here, the electric drive device 4 is particularly advantageous, since vertical displacement of the window 2 by the electric drive device 4 is considerably simplified and a one-piece window 2 can also be completely shifted. In the 1 to 3 a preferred embodiment is shown with a vertically displaceable window 2.

Alternatively, it can be provided that the window 2 is essentially laterally displaceable along the guide rails 3.

In particular, it can be provided that the window 2 can be shifted between a first position and a second position, wherein in the first position of the window 2 is in a position projecting the window opening 6 and the second position represents the position of the window 2 at maximum opening .

It can further be provided that the window 2 can assume a third position arranged between the first position and the second position, the third position in particular representing a ventilation position. The third position can be shifted from the first position by 10 cm to 20 cm, in particular shifted downwards. In Fig. 1 the window 2 of the preferred embodiment is in the first position, in Fig. 2 in the third position and in Fig. 3 shown in the second position.

It can further be provided that the first position, the second position and the third position of the window 2 are stored in the drive device 4, in particular the control unit of the drive device 4. This allows the user to quickly and easily switch between these three positions.

Furthermore, it can be provided that the drive device 4 can position the window continuously between the first position and the second position.

Furthermore, a building 9 is provided which includes the building sliding window device 1. In the Fig. 1 and 3rd is only part of building 9 Outer wall 13 and a bottom 16 shown.

Furthermore, it can be provided that the building sliding window device 1 has a window opening 6 that can be closed by the window 2.

It can be particularly preferably provided that the window 2, the guide rails 3 and the electric drive device 4 are arranged in a housing 5, the housing 5 having a window opening 6 which can be closed by the window 2. The housing 5 can in particular form an essentially closed shell, the window opening 6 forming an opening on both sides of the housing 5 that can be closed by the window 2. Furthermore, it can be provided that the building sliding window device 1 essentially forms a plate when the window 2 is closed, that is to say when the window 2 is in the first position. Due to the housing 5, the building sliding window device 1 can simply be used as an essentially complete module in the construction of a building 9 and / or subsequent application of external thermal insulation in a building 9.

In particular, it can be provided that the window opening 6 has a, in particular circumferential, seal for the window 2 on at least one side. The seal can in particular be arranged on an outward-facing side of the window opening 6.

In particular, it can be provided that the housing 5 encloses a receiving space 10 for the window 2, wherein in particular the window in the maximum open position, that is to say the second position, can be arranged essentially completely in the receiving space 10. The enclosed receiving space 10 can prevent the window 2 from knocking over objects in the room or injuring someone when it is opened.

In particular, provision can be made for the receiving space 10 to be arranged below the window opening 6, the window 2 being moved downward when it is opened.

It can further be provided that the window opening 6 is essentially the size of the window 2. As a result, the window opening 6 can essentially fully released from window 2.

The building sliding window device 1 can in particular be arranged in an outer wall 13 of the building 9. In this case, the outer wall 13 can have an opening 14 which is essentially aligned with the window opening 6.

A building sliding window device 1 arranged in the outer wall 13 is exemplified in the preferred embodiment in FIGS 1 to 3 shown. Here, parts of the outer wall 13 and parts of the housing 5 are cut away in order to expose the inside of the sliding window device 1.

Alternatively, it can be provided that the building sliding window device in a building 9 is arranged in an external wall insulation, in particular subsequently applied. Here, during the subsequent thermal renovation of a building 9, an old window can be completely removed, and thus the opening 14 can be uncovered, the sliding window device 1 being simply attached to an outside of the outer wall 13, as a result of which thermal insulation also quickly occurs in the windows 2 of a building 9 and can be done easily.

It can particularly preferably be provided that the housing 5 is thermally insulated. Here, the housing 5 may have a layer of a thermal insulation material on the inside. If the window 2 also has the usual thermal insulation measures, for example a multiple glass, the entire building sliding window device 1 can thus be designed as part of the thermal insulation of the building 9, and additional thermal insulation in the area around the receiving space 10 is not required.

In particular, it can be provided that the electric drive device 4 has a motor 7 and a tension element 8, that the window 2 is at least indirectly attached to the tension element 8, and that the motor 7 is at least indirectly positively connected to the tension element 8 around the tension element 8 to move. The pulling element 8 transmits the movement of the motor 7 to the position of the window 2. Since the pulling element 8 is at least indirectly positively connected to the motor 7, in particular via a gear, and is also at least indirectly attached to the window 2, the window 2 is moved positively via the pulling element 8. As a result, the drive device 4 can precisely determine the position of the window 2.

In particular, the transmission can be self-locking, so that the transmission counteracts a displacement of the window 2 when the motor 7 is switched off. Alternatively, it can be provided that the drive device 4 is hydraulic.

Furthermore, it can be provided that the drive device 4 has a plurality of motors 7, in particular one motor 7 per guide rail 3. Furthermore, it can be provided that each motor 7 moves a respective tension element 8.

According to the pulling element 8 is flexible and guided in a sleeve. The force of the motor 7 can be deflected by the flexible tension element 8, whereby a compact design is possible. By guiding the tension element 8 in a sleeve, the tension element 8 can be subjected to both tension and pressure, such as a Bowden cable, whereby the window 2 is reliably fixed in position in both directions by the tension element 8. In particular, it can be provided that the motor is arranged in the region of an upper side of the housing 5, in particular above the window opening 6. As a result, the tension element 8 remains under tension. Furthermore, the drive device 4 can thereby be protected against moisture penetrating into the receiving space 10.

The flexible tension element 8 is a laterally toothed cable or a toothed belt. Furthermore, it can be provided that the pulling element has two ends, the window 2 being indirectly attached to a first end. A counterweight can in particular be arranged at a second end opposite the first end. The gear of the motor 7 can be in particular in a range between the two ends with the tension element 8 in a positive connection and move it in this way.

It can be particularly preferred that the window 2 has a fall protection 15 designed as a cross member on an upper side. A fall protection device 15 is a device that prevents a person from falling out of an open window opening 6, in particular if the window opening 6 essentially extends to the floor. Such a fall protection 15 is particularly necessary if, in the installed state of the sliding window device 1, a lower edge of the window opening 6 is arranged below a required minimum height compared to the floor 16. The arrangement of the fall arrest device 15 directly on the top of the window 2 means that an additional railing can be dispensed with.

The upper window frame 11 can preferably form the fall protection 15, in particular by means of a continuous cross member which is integrated in the window frame 11.

Furthermore, the second position of the window, which corresponds to the maximum open position, in particular when installing the building sliding window device 1, can be set such that the top of the window 2 is at the level of the legally prescribed minimum height of the fall protection device 15, in particular by attaching a mechanical one Lock in the area of the guide rails 3. This allows a window opening 6 reaching to the bottom to be easily realized, ensuring that the window 2 can only be moved down to a minimum height and that the top of the window 2 is mechanically stable enough restrain a person.

Furthermore, it can be provided that the window 2 is connected to the guide rails 3 via a closure device, and that the closure device moves the window 2 transversely to a longitudinal direction of the guide rails 3 between a release position and a closed position. In particular, it can be provided that the closure device is designed, the window 2 can be predetermined transversely to the longitudinal direction of the guide rails 3 between the Release position and the closed position to move. By means of the closing device, the window 2 can be predetermined to be moved transversely to the longitudinal direction of the guide rails 3, that is to say normally or obliquely to this longitudinal direction. It can be provided here that the window 2 in the closed position is pressed by the closing device against a seal of the window opening 6, as a result of which the window 2 closes the window opening 6 tightly in the first position, and that for moving the window 2 through the window 2 Closure device is lifted from the seal, whereby the window 2 can be moved in the release position without damaging the seal. Furthermore, it can be provided that the window 2 is pressed against the seal of the window opening 6 in the closed position by the closing device, and that the window 2 is lifted off the seal in the release position for moving the window 2 through the closing device.

Furthermore, it can also be provided that the window is also pressed in a position other than the first position in the closed position at least against one, preferably lowest, seal of the window opening 6. This can prevent rainwater from entering the receiving space 10.

The locking device can in particular have a plurality of locking mechanisms, each of which connects the window 2 to one of the guide rails 3, so that the window 2 is only connected to the guide rails 3 via the locking mechanisms. In particular, at least two locking mechanisms can be provided per guide rail 3. As a result, the window 2 can be moved together with the locking mechanisms in the longitudinal direction of the guide rail 3, the locking mechanisms permitting an additional movement of the window 2 transversely to the longitudinal direction of the guide rails 3, whereby a decoupling of these two movements is achieved.

The tension element 8 can in particular engage at least one of the locking mechanisms.

The locking mechanisms can in particular have their own motor.

Furthermore, it is provided that several catches are arranged in the region of the guide rails 3, and that projections are arranged on the window 2, in particular on the window frame 11, the projections being arranged in at least one catch in the closed position, and out of engagement in the release position are resting. The catches can in particular be arranged such that the projections of the window are arranged in catches in the first position. Further catches, in particular for the second position and / or the third position of the window 2, can preferably be arranged. As a result, the window 2 can be snapped into place by the locking device, which provides additional protection against break-ins, but also relieves the drive device 4 in the locking position.

Furthermore, a locking device with extendable locking bolts can be provided, which locking bolts are movably arranged in the window 2 and / or the locking device, the locking bolts extending in a locking position and engaging in openings in order to lock the position of the window. In particular, the locking device can be designed to lock the window 2 in the first position.
