Description

The present invention relates to a component for closing a wall opening, with a pivoting about a pivot axis arranged on a rectangular frame arranged closing element, wherein the pivot axis substantially within the frame defined by the frame, flat surface relative to the frame along parallel aligned frame members transverse to its longitudinal extension is arranged to be movable and has end bearing elements which are each arranged at least partially engaging in a guide of one of the parallel aligned frame members, wherein the guide is arranged substantially along the entire longitudinal extent of an associated frame member.

Such a device may be formed, for example, as a window, door, bulkhead or the like. Each of these components has at least one closing element, which is arranged pivotably about a pivot axis on a frame and can also be referred to as a wing. Most of the frames of such devices are rectangular, and it should not be excluded in the context of the present invention, when the frame deviates from the ideal shape and has, for example, rounded corners or the like. The rectangular design of the frame should also include the special case of the square design of the frame.

In order to be able to arrange the closing element in the closed position of the component both in a first position and in a position rotated by 180 ° on the frame of the component, variously configured components have been proposed which allow a displacement of the pivot axis relative to the frame from one end position to another end position. If the pivot axis is in one of these end positions, the opening of the component takes place, for example, by pivoting the closing element, whereby this pivoting takes place counter to the pivoting which is performed when the component is opened, when the pivot axis is arranged in the other end position.

This known embodiment of a component in which a displacement of the pivot axis can be made relative to the frame, whereby the closing element with respect to the frame can be selectively arranged in one of two closed positions, for example, the creation of a window which allows a good control of the heat balance. Such a window with single or multiple glazing may be designed, for example, such that partial heat radiation from one side onto the glazing, such as sunlight, is partially reflected, so that a space arranged on the other side of the glazing or of the component does not overheat becomes. This use of a component is particularly advantageous in the summer. In winter, however, it is preferred to arrange the closing element in its second, to the above-described rotated by 180 ° closed position, whereby in the room existing heat is partially reflected on the glazing and thus prevented from excessive escape through the device.

The European patent specification EP 0 795 072 B1 is to take a corresponding window in which a sash frame is rotatably mounted on hinges in a window frame. The hinges are slidably mounted in guides of the horizontally oriented frame members of the window frame, wherein a corresponding pivoting of the sash frame relative to the window frame is carried out with the aid of a rotating mechanism. This has two pivotally interconnected link arms, which are arranged below the sash frame and support the intended pivoting of the sash frame.

A similar mechanism is in the European patent specification EP 1 419 306 B1 disclosed, wherein in the disclosed therein design of a window, the corresponding pivot axis is arranged horizontally, while the pivot axis is aligned vertically with respect to the European patent described above.

More complicated embodiments of such rotary mechanisms for supporting the pivoting movement of a pivotable by 180 ° arranged closing element or window sash frame on a window frame are by the international patent application WO 2006/042438 A2 , the U.S. Patent US 2,718,675 and the German patent DE 21 25 639 discloses, in each of which pivotally interconnected pivot arms are provided to support the pivoting of the Fensterflügclrahmens.

An alternative embodiment to this is by the US patent US 3,638,360 in which the disclosed rotary mechanism comprises a frame having pivotally interconnected links whereby the arm performs an accordion-like motion upon pivoting of the sash frame.

All these above-described embodiments of components in which a closing element can be optionally arranged in one of two different closing positions on a frame, has in common that are used for proper and safe pivoting of the closing element complex support structures, which are arranged on one side of the device and therefore claim a corresponding space, which precludes unrestricted use of such devices. In particular, when such a device is to be used as a window with previously arranged flower boxes or the like, the disturbing effect of such support structures occurs. In addition, such support structures are exposed in the arrangement on the outside, for example, a house of the weather, which permanently impair their functioning over time. By contrast, an arrangement of such support structures on the inside, ie on a side facing the space of the component, Not much desirable, since such a design is not least handsome and also takes a lot of space. Furthermore, the use of such support structures can not ensure that the guided during pivoting of such a closing element in guides of parallel aligned frame members bearing elements synchronously, which may for example have a tilting of the closing element to the frame result, making the handling of such a device is difficult and damage to the device can not be excluded.

Based on this prior art, it is the object of the present invention to provide a device for closing a wall opening, which is easy and safe to handle and very flexible.

This object is achieved by a component according to claim 1, which has a device for synchronizing the movements of both bearing elements. Advantageous embodiments of the invention are disclosed in the subclaims.

According to the invention, a component is thus proposed in which a proper and secure handling of the component is ensured by the synchronization of the movements of the two bearing elements during the displacement of the pivot axis relative to the frame. In addition, it is ensured by the synchronization of the movements of the bearing elements that the functionality of the device is not affected even when using relatively heavy and / or large-scale closure elements, so that the functionality of the device is very durable. Tilting or the like, as may occur in the prior art devices during the displacement of the pivot axis relative to the frame, is thus not possible in the device according to the invention, even if relatively large or heavy closure elements are used, in their pivoting large lateral forces occur can, which are not compensated by components of the prior art, which is the use of these known Significantly restricts components compared to the device according to the invention. The device according to the invention is thus very simple and safe to handle and versatile.

As already described above, the component may be a window, a door, a bulkhead or the like. It is of interest that the corresponding closing element has two large surfaces whose material properties are different, so that the closing element can be arranged depending on the purpose, optionally in one or the other closing position on the frame. Examples of such material properties are thermal insulation, fire resistance, corrosion resistance, dimensional stability, color design and the like.

According to an advantageous embodiment of the invention, the device has two each arranged in one of the parallel aligned frame members racks, each cooperating with a arranged on a bearing element gear, wherein the gears are rotatably connected to each other via a shaft. This embodiment of the device for synchronizing the movements of the two bearing elements is relatively simple and therefore inexpensive. In addition, it has the advantage that the mechanical components of the device are arranged within the components of the component, so that no disadvantageous support structure, as occurs in the components of the prior art, is required. In this respect, this embodiment also has a positive effect on the flexible applicability of the component according to the invention, since the structural expansions of the component according to the invention is not changed by the arrangement of the device for synchronizing the movements of the two bearing elements. The components of the device are thus also protected from external influences. Furthermore, the visual impression caused by the device is not affected by the device, since its components are not visible at the sight of the device. Thus, a structurally very attractive and at the same time very functional as well as flexibly usable component is provided by this embodiment, the functionality of which is very durable, since the device is arranged to synchronize the movements of the two bearing elements protected within components of the device.

In order to further improve these properties, namely the flexible usability, the optical resiliency and the long-lasting functionality, it is proposed with an advantageous embodiment of the invention that the shaft is arranged at right angles to the frame elements oriented parallel to one another substantially within the closing element and over at least two Shaft bearing is stored. In addition to the protected from external influences arrangement of the racks and gears of the device in the guides of the mutually parallel frame members thus additionally arranged at right angles to these frame elements shaft is arranged protected within the closing element. If the relevant component is designed, for example, as a window, then the shaft can be arranged in a closing wing frame element arranged perpendicularly to the window frame elements oriented parallel to one another, without the need for additional structural measures.

A further alternative embodiment of the component according to the invention proposed as an alternative to the preceding embodiment is characterized in that the device has two rotatably mounted screw spindles each arranged in one of the parallel aligned frame members, each cooperating with a spindle nut fixedly mounted on a bearing member. By a rotation of the screw spindles, a controlled displacement or movement of the two bearing elements can be effected by the spindle nuts change their position along the parallel aligned frame elements upon rotation of the screw spindles. In particular, care must be taken that the screw spindles rotate synchronously to ensure the synchronous movement of the locking elements. The screw spindles can be arranged for example via corresponding bearing elements in the frame elements.

For optimal synchronization of the rotation of the screw spindles and thus the Rewegungen the two bearing elements is proposed that the Screw spindles are each connected via a bevel gear with a shaft which is arranged within a perpendicular to the frame members arranged parallel to each other arranged frame member and mounted on at least two shaft bearings. This very simple embodiment of the device for synchronizing the movements of the bearing elements is very effective and feasible using a very small number of components. It should only be noted that the screw spindles rotate in opposite directions, which can be compensated by a corresponding design of the existing threaded parts on the screw spindles and / or the spindle nuts.

According to a further, alternative and advantageous embodiment of the invention, the device has two fixedly arranged respectively in one of the mutually parallel arranged frame elements screw spindles, each cooperating with a rotatably mounted on a bearing element spindle nut. Here, therefore, a synchronous movement of the bearing elements is generated by a synchronous rotation of the spindle nuts, for which purpose the spindle nuts are rotatably arranged on the bearing elements.

Also, in the above-described embodiment of the device according to the invention, it is considered advantageous if the spindle nuts are rotatably connected to each other via a bevel gear and a shaft, wherein the shaft is arranged at right angles to the parallel frame members substantially within the closing element and at least two shaft bearings is stored. This creates the already described advantages of synchronizing the movements of the bearing elements in a simple manner using a very small number of components.

It is also proposed that the device for synchronizing the movements of the bearing elements comprises a drive unit. About this drive unit, which is formed for example manually or by electric motor, a synchronous movement of the bearing elements and thus a proper pivoting of the closing element can take place, wherein the use of such a drive unit for the device or the component is advantageous if the closing element is formed over a relatively large area and / or heavyweight.

As usual, this window has a frame 2 and a closing element 3. In this embodiment, the closing element 3 has a closing frame 4, which is formed from four closing frame elements 5. The frame 2 also has four frame members 6.

The closing element 3 is arranged pivotably on the frame 2 via a pivot axis 7, which end bearing elements 8 has. These bearing elements 8 are jewells In a guide 9 of one of the mutually parallel and horizontally oriented frame members 6 are arranged. This makes it possible to shift the pivot axis 7 with the bearing elements 8 along the longitudinal extent of the parallel to each other and horizontally oriented frame members 6, so that during a displacement of the pivot axis 7 of the left in FIG. 1a shown end position in the right in FIG. 1a shown end position, a pivoting of the closing element 3 by 180 "can take place, whereby either one or the other position is selected to turn a desired of the two large surfaces of the closing element 3 to a specific side of the device 1.

Thus, the movements of the two bearing elements 8 are synchronized in the guides 9, for example, to prevent tilting of the closing element 3 during the displacement of the pivot axis 7, a device for synchronizing the movements of the two bearing elements 8 is provided according to the invention, which is more precisely based on FIG. 1b is explained.

FIG. 1b shows a sectional view of the in FIG. 1 shown component 1 along the line AA. It is the upper, horizontally oriented frame member 6 of the frame 2 to see in a longitudinal cross-section, wherein the bearing element 8 is formed as a gear and cooperates with a rack 10. Furthermore, a guide opening 11 can be seen, in which an end area of the pivot axis 7 is guided. In order to achieve a synchronization of the movements of the two bearing elements 8, also in FIG. 1a shown below bearing element 8 as in FIG. 1b illustrated bearing element 8 is formed as a gear and it is also a rack 10 is provided in the lower frame member 6 of the frame 2, wherein the synchronization of the movements of the two bearing elements 8 by connecting the bearing elements 8 with a shaft 12, with the bearing elements 8 rotatably connected are. If now the closing element 3 located in the closed position is opened out of the image plane, a displacement of the pivot axis 7 or of the shaft 12 with respect to the axis of rotation can take place

In the guides 9, screw spindles 13 are rotatably mounted in this embodiment, which cooperate with spindle nuts, not shown, which are arranged on the bearing elements 8. Upon rotation of the screw spindles 13 thus takes place a movement of the bearing elements along the longitudinal extent of parallel aligned horizontally disposed frame members 6 of the frame 2. To synchronize these movements, the screw spindles 13 are connected via not shown in detail bevel gear 14 with a shaft 15, so that upon rotation of the shaft 15 a synchronous rotation of the two screw spindles 13 and thus a synchronous movement of the bearing elements 8 along the longitudinal extent of the guides 9 takes place. For this embodiment, either the thread directions of the screw spindles 13 or the spindle nuts must be different, so that the spindle nuts and thus the bearing elements 8 move in rotation of the shaft 15 in the same direction.

This rotation is about the in FIG. 2a shown shaft 15 and a translation of the rotation of the shaft 15 via a bevel gear 14 is generated. Also in this embodiment of the component 1, a guide opening 11 is provided, in which a massively ausgeblldeter, connected to the bearing element 8 part of the pivot axis 7, which essentially connects the closing frame 4 with the bearing element 8, is present and guided.

In FIG. 3a is a further alternative embodiment of the device 1 according to the invention shown schematically. Also, this device 1 is formed as a window and has a frame 2 with four frame members 6 and a pivotally arranged thereon closing element 3 with four closing frame 4 forming closing frame elements 5, wherein the pivoting of the closing element 3 relative to the frame 2 via a pivot axis 7 with one side arranged bearing elements 8 takes place. The bearing elements 8 are movable along the longitudinal extent of parallel aligned, horizontally arranged frame members 6 within guides 9.

Unlike in the FIGS. 2a and 2b In the embodiment shown here, the screw spindles 13 arranged essentially in the guides 9 are arranged in a fixed position, the spindle nuts cooperating with the screw spindles 13 being rotatably arranged on the bearing elements 8 in this embodiment and rotating via a solid shaft (not illustrated) can be offset, which occupies the same position as the pivot axis 7 in this embodiment. By rotation of this substantially corresponding to the pivot axis 7 shaft thus the spindle nuts are synchronously rotated, so that the latter move along the stationary held spindle screws 13, which means a synchronization of the movements of the bearing elements 8. The connection of the spindle nuts to the in Essentially the pivot shaft 7 corresponding shaft is also realized here by the respective use of a bevel gear 14.
