Description

[0001] The invention relates to a box window. background

[0002] Box windows usually have an inner and an outer window level, each with one or more window sashes.

[0003] Document DE 20 2014 106 055 U1 discloses a casement window with an inner and outer window plane, with inner and outer window sashes that can be tilted and / or rotated for opening and closing, i.e., pivoted or rotated about a horizontal and / or vertical axis. The inner and outer window sashes can each be opened and closed individually. This means that to open one of the outer window sashes, at least one of the inner window sashes must first be opened to allow access to operate one of the outer window sashes. Summary

[0004] The object of the invention is to provide an improved box window in which the opening of an outer window sash is facilitated.

[0005] To solve this problem, a box window is created according to independent claim 1. Further embodiments are the subject of dependent subclaims.

[0006] According to one aspect, a box window is provided which comprises the following: an outer window plane with an outer window sash, to which a displacement mechanism is assigned, with which the outer window sash can be displaced between a closed and a tilted window sash position for closing and opening; an inner window plane with an inner window sash, to which an actuating mechanism with an actuating element is assigned, wherein the actuating element is displaceable between a first element position, in which the inner window sash cannot be opened, and a second element position, in which the inner window sash can be opened; a box space formed between the outer and the inner window plane, and a transmission mechanism.The transmission mechanism is coupled to the displacement mechanism and to the actuating mechanism and is configured to (i) pick up a first element-side displacement movement of the actuating element during displacement from the first to the second element position and / or a first component-side displacement movement of a component which is functionally connected to the actuating element in the actuating mechanism and is movable due to the displacement of the actuating element from the first to the second element position, and (ii) transfer the picked up first element-side and / or the picked up first component-side displacement movement to the displacement mechanism in such a way that the outer window sash is thereby moved from the closed to the tilted window sash position.

[0007] In the proposed casement window, the outer window sash can be at least partially opened in a simplified manner by detecting a displacement movement of the actuating element itself and / or of another component of the actuating mechanism, which in turn is displaced or moved due to the actuation of the actuating element, on the inner window sash as a result of the actuation of the actuating element. This displacement movement is transmitted to the displacement mechanism of the outer window sash by means of the transmission mechanism. As a result, the outer window sash is displaced from the closed to the partially open sash position by means of the displacement mechanism assigned to it, thereby partially opening the window sash. Thus, there is no need to open the inner window sash beforehand in order to move the outer window sash from the closed to the partially open sash position.

[0008] The actuation of the actuating element, which is part of the actuating mechanism assigned to the inner window sash, for moving from the first to the second element position and the resulting movement of the outer window sash from the closed to the partially open window sash position form a coupled actuation of the actuating element on the inner window sash and the outer window sash.

[0009] The outer window sash can be moved from the closed to the partially open position by pivoting the outer window sash about a horizontal or vertical pivot axis. For example, the outer window sash can be moved from the closed to a tilted sash position, which corresponds to pivoting the window sash about a horizontal pivot axis. Alternatively, it can be provided that the window sash is pivoted about a vertical pivot axis in the partially open sash position relative to the closed sash position and is thus partially opened, in contrast to a full opening in which the outer window sash, starting from the closed sash position, is pivoted about the vertical pivot axis by at least approximately 90 degrees.The outer window sash can assume the partially open window sash position in particular when all inner window sashes are closed, if the inner window level has one or more inner window sashes.

[0010] In one example, the outer window sash can be moved into the partially open sash position by actuating or adjusting the actuating element without the inner window sash itself being open, even if the actuating element is arranged in the second element position, in which the inner window sash can be opened. In this example, the outer window sash is thus moved into the partially open sash position, even if the inner window sash is still arranged in the closed sash position.

[0011] In one example, it can be provided that the partially opened window sash position of the outer window sash no longer changes, i.e. for example in particular a tilt angle of a tilted window sash position is not changed when the inner window sash itself is moved from the closed window sash position to an open window sash position, be this a partially opened window sash position or a fully opened window sash position.

[0012] In the actuating mechanism, which is assigned to the inner window sash, the component can be arranged downstream of the actuating element in a mechanical chain of action, such that the actuation of the actuating element, for example by rotating, pivoting and / or shifting the actuating element, causes a displacement movement of the component, which can then be picked up by the transmission mechanism.

[0013] Embodiments can be provided in which the inner and / or outer window plane has at least one further (inner or outer) window sash.

[0014] The inner window sash can be displaced into a tilted and / or fully open sash position for opening when the actuating element is arranged in the second element position. Different embodiments can be provided for the inner window sash. It can be a window sash that can only be tilted about a horizontal tilt axis for opening, or can only be rotated or pivoted about a vertical rotation or pivot axis. Alternatively, it can be provided that the inner window sash can be both tilted (about the horizontal axis) and pivoted (about the vertical axis) for opening.

[0015] For the outer window sash, it can be provided that it can not only be moved into the partially open window sash position for opening, but can also be rotated about a vertical rotation or pivot axis for full opening, in particular to enable shock ventilation.

[0016] With respect to the inner and outer window planes, the inner window sash and the outer window sash can be arranged at least partially offset from one another along at least one of the following directions: horizontal direction and vertical direction. With respect to the inner and outer window planes, the inner and outer window sashes can be arranged so as not to overlap at all, i.e., completely offset from one another. Alternatively, it can be provided that the inner and outer window sashes are not offset from one another.

[0017] The transmission mechanism can further be configured to (i) pick up a second element-side displacement movement of the actuating element during displacement from the second to the first element position and / or a second component-side displacement movement of the component which is movable due to the displacement of the actuating element from the second to the first element position, and (ii) transfer the picked up second element-side and / or the picked up second component-side displacement movement to the displacement mechanism in such a way that the outer window sash is thereby moved from the partially open to the closed window sash position.In this embodiment, it is provided that the actuation or adjustment of the actuating element on the inner window sash not only causes or forces the displacement of the outer window sash into the partially open sash position (forced displacement), but an opposite actuation of the actuating element when moving the actuating element from the second to the first element position causes a comparable displacement of the outer window sash from the partially open to the closed sash position. In this case, the second element-side displacement movement can be directionally opposite to the first element-side displacement movement. Alternatively or additionally, the second component-side displacement movement can be directional opposite to the first component-side displacement movement.

[0018] This makes it possible to move the outer window sash between the closed and the partially open window sash position by operating the operating element on the inner window sash in both directions, i.e. for opening as well as for closing.

[0019] At least one of the following configurations can be provided: the displacement mechanism associated with the outer window sash is formed with a skylight opener device; and the actuating mechanism associated with the inner window sash is formed with a tilt-and-turn window fitting, which comprises the actuating element and the component. Skylight openers are known as such in various embodiments and typically enable a window sash to be displaced between a closed and a partially open sash position, in particular to tilt the sash. In the version with a skylight opener, as well as in alternative configurations, the displacement mechanism can be formed, for example, with a single- or multi-part rod assembly.In embodiments, the displacement mechanism may connect the outer window frame of the casement window and the outer window sash such that the outer window sash is displaceable relative to the outer window frame.

[0020] Tilt and turn window fittings are also known as such in different variants and are used to enable window sashes to be tilted into a partially open window sash position as well as to be turned or pivoted into an open turn or pivot position, whereby the window sash can be opened completely, for example for shock ventilation.

[0021] In this or other embodiments, the component of the actuating mechanism can be arranged on a side surface of a casement of the inner window sash. For example, the component can be a flat component that is movably arranged on the casement, particularly in the region of a side surface of the casement.

[0022] Designs can be provided in which the window fitting of the inner window sash is only designed for a tilt opening or only for a turn opening.

[0023] The transmission mechanism can have a pickup device that engages the actuating element and / or the component to pick up the respective displacement movement. The pickup device can be formed, for example, with a claw and / or a pickup with which the respective displacement movement of the actuating element and / or the component is mechanically picked up. The pickup device can be configured to pick up or receive a rotary and / or linear movement of the actuating element and / or component. The pickup device can be at least partially integrated into the sash frame of the inner window sash, for example in an associated recess in the sash frame.

[0024] The gripping device can be formed at least partially on the inner side of an inner window frame of the inner window sash. The inner window sash is received in the inner window frame of the casement window. When the gripping device is arranged at least partially on the inner side of the inner window frame, the gripping device can be arranged adjacent to components of the window fitting of the inner window sash, in particular opposite them, at least when the inner window sash is arranged in the closed position.

[0025] The engagement between the pick-up device and the actuating element and / or the component can be released when the inner window sash is arranged in an open window sash position. In this embodiment, the engagement between the pick-up device of the transmission mechanism, on the one hand, and the actuating element and / or the component, on the other hand, is released when the inner window sash is arranged in the open window sash position, be this a tilt position or a (fully) open rotating or pivoting position of the window sash.

[0026] In these or other embodiments, the tapping device can engage the actuating element and / or the component directly or indirectly via components arranged therebetween which mediate the mechanical engagement, such that the displacement movement can be tapped and transmitted by means of the transmission mechanism.

[0027] The tapping device can be designed to be self-adjusting with respect to the actuating element and / or the component when the engagement is formed. For this purpose, the tapping device can be arranged to be displaceable, in particular displaceable and / or rotatable. In this way, it can be achieved that the engagement between the tapping device, on the one hand, and the actuating element and / or component, on the other hand, can be re-established even if the tapping device and / or the actuating element / component have shifted during the released engagement. In particular, the self-adjusting design of the tapping device can assist in forming the engagement when the inner window sash is closed.

[0028] The transmission mechanism can be configured to transmit at least one of the following forces: tensile force and thrust force, for transmitting the respectively sensed movement. In this or other embodiments, the transmission mechanism can be formed, for example, with a Bowden cable and / or a rod, which respectively enable the transmission of tensile and / or thrust forces. In this case, it can be provided that, for example, the tensile force can be used to move the outer window sash into the partially open or closed position. Similarly, the thrust force can cause the outer window sash to move into the partially open or closed position.

[0029] In one embodiment, it can be provided that the displacement of the outer window sash into the partially open sash position occurs against a preload force, in particular by means of a tensile force. The preload force causes the outer window sash to return to the closed sash position when the tensile force is no longer applied by the transmission mechanism. The preload force can, for example, be provided as a spring force that counteracts the displacement of the outer window sash into the partially open sash position. For example, skylight openers are known that provide such a preload force.

[0030] The transmission mechanism can be arranged at least partially within the box space. For example, the Bowden cable and / or the linkage can extend at least partially through the box space, particularly along the edge.

[0031] The box space can be bounded laterally, at least in part, by a window frame, and the transmission mechanism can be arranged at least partially on the window frame. The window frame laterally bounds the box space between the outer and inner window planes. The transmission mechanism can be arranged partially on an inner side of the window frame facing the box space.

[0032] A cover can be assigned to the transmission mechanism in the box space. The cover is designed to cover the transmission mechanism in the area of ​​the box space, for which purpose one or more cover components can be arranged in the box space. Description of implementation examples

[0033] Further embodiments are explained below with reference to the figures of a drawing. Herein: Fig. 1 a schematic perspective view of a box window; Fig. 2 a schematic representation of the box window from Fig. 1 from above and Fig. 3 a schematic perspective view of another box window.

[0034] Fig. 1 shows a schematic perspective view of a box window 1 with an inner window plane 2 and an outer window plane 3. In the inner window plane 2, a first and a second inner window sash 5.1, 5.2 are arranged in an inner window frame 4, which can be tilted about a horizontal axis and / or rotated or pivoted about a vertical axis for opening, as is known per se for box windows.

[0035] At the outer window level 3, a first and a second outer window sash 7.1, 7.2 are arranged in an outer window frame 6. At least the second outer window frame 7.2 can be moved into a partially open window sash position for opening, as shown in Fig. 1 shows an example of a tilted window sash position. If the first inner window sash 5.1 is partially opened at the same time, and here also tilted, ventilation can take place, as shown in Fig. 1 is shown schematically by means of an arrow A.

[0036] To operate the first inner window sash 5.1, an actuating mechanism 8 with an actuating element 8.1 is assigned to it, here, for example, a rotatable or pivotable handle or lever, wherein the actuating mechanism 8 is formed, for example, with a turn-tilt window fitting. Turn-tilt window fittings are known in various embodiments. Upon actuation, the actuating element 8.1 is displaceable between at least a first element position, in which the first inner window sash 5.1 cannot be opened, and a second element position, which Fig. 1 and enables the opening of the first inner window sash 5.1 into the tilted window sash position shown.

[0037] On the second outer window sash 7.2, a displacement mechanism 9 is provided, which is, for example, a skylight opener, for which different embodiments are known as such and which enables the displacement of the second outer window sash 7.2 between the Fig. 1 shown partially open, here tilted, window sash position and the closed window sash position, wherein the displacement mechanism 9 holds the second outer window sash 7.2 in the open state in the Fig. 1, in particular in such a way that further tilting is prevented.

[0038] For the box window 1 according to Fig. 1, a transmission mechanism 10 is provided, which in Fig. 1 is shown schematically by means of a double arrow. The transmission mechanism is mechanically coupled, on the one hand, to the actuating mechanism 8 of the first inner window sash 5.1 and, on the other hand, to the displacement mechanism 9, which is assigned to the second outer window sash 7.2. The transmission mechanism 10 is formed, for example, with a Bowden cable and / or a rod and makes it possible to mechanically pick up an element-side displacement movement of the actuating element 8.1 from a first to a second element position, for example a rotation or pivoting of the actuating element 8.1, for example by means of a claw or a pickup, and to transmit it to the displacement mechanism 9 of the second outer window sash 7.2, such that the second outer window sash 7.2 is then moved from the closed window sash position into the Fig. 1 shown partially open / tilted window sash position. In one embodiment, it is provided that the displacement of the second outer window sash 7.2 into the tilted window sash position according to Fig. 1 due to the effect of the transmission mechanism 10 already occurs when the first inner window sash 5.1 itself is not opened at all (in contrast to Fig. 1), that is to say in particular it is not tilted, but only the actuating element 8.1 is arranged in the second element position, which is Fig. 1 and which enables or permits the opening (e.g., tilting) of the first inner window sash element 5.1. The second outer window sash 7.2 is then tilted even before the first inner window sash 5.1 is actually opened.

[0039] It can further be provided that the transmission mechanism 10 is designed such that the return displacement of the actuating element 8.1 from the second to the first element position causes the displacement of the second outer window sash 7.2 from the tilted to the closed position (not shown). For this purpose, the corresponding displacement movement of the actuating element 8.1 of the actuating mechanism 8 on the first inner window sash 5.1 is mechanically picked up by means of the transmission device 10 and transferred to the displacement mechanism 9 on the second outer window sash 7.2. This is possible in particular when the first inner window sash 5.1 is moved from the Fig. 1 shown tilted window sash position into the closed window sash position (not shown), which then causes the turning or displacement of the actuating element 8.1 from the position shown in Fig. 1 shown second element position into the first element position.

[0040] In the exemplary embodiment of the box window in Fig. 1, the first inner window sash 5.1 and the second outer window sash 7.2 are arranged offset from one another in the horizontal direction. In alternative embodiments, window sashes whose actuation is coupled by means of the transmission mechanism 10 in the manner described can fully or partially overlap with respect to the inner and outer window planes 2, 3.

[0041] Fig. 2 shows a design of the box window 1 according to Fig. 1 a schematic representation from above. For the same features, Fig. 2 the same reference numerals as in Fig. 1 is used. The transmission mechanism 10 has a pickup device 10.1, which is designed to mechanically pick up the displacement movement of the actuating element 8.1, such that the picked up displacement movement can then be transferred by means of the transmission mechanism 10 to the displacement mechanism 9, which is assigned to the second outer window sash 7.2, so that the second outer window sash 7.2 can be forced (under the constraint of the transferred movement) between the closed window sash position (cf. Fig. 2) and the partially open window sash position (cf. Fig. 1) is relocatable.

[0042] In the example in Fig. 2, the transmission mechanism 10 is arranged at least partially in a box space 20, which is formed between the inner and outer window planes 2, 3. Laterally, the box space 20 in the embodiment in Fig. 2 bounded by a window frame 21.

[0043] The pick-up device 10.1 of the transmission mechanism 10 engages in the example shown in Fig. 2, a displacement movement of a component 8.2 of the actuating mechanism 8, which is functionally connected to the actuating element 8.1 in the actuating mechanism 8, such that the displacement of the actuating element 8.1 between the first and second element positions causes a displacement of the component 8.2 between a first and a second component position. For example, the component 10.2 can be an element of a window fitting assigned to the first inner window sash 5.1.

[0044] Fig. Figure 3 shows a schematic perspective view of another box window 30, in which the window sashes intended for coupled operation are arranged offset from one another in the vertical direction. For the same features, Fig. 3 the same reference numerals as in Fig. 1 and Fig. 2 used.
