Description

Device for a window

The present invention relates to an arrangement for a window or some other covering element, which exhibits a window casement or some other outer casement for a covering element pivotally mounted and capable of being accommodated in a window frame or some other frame. Ventilation is normally performed in windows by causing the window to be opened to the desired degree. By opening the window by only a small amount, it is normally possible to ^'cause it to be locked in the opened position by precisely as much as the window has been opened. There may be persons who are able to open the window from the outside, however, in order to gain access through the window opening into the area concerned that is normally covered by the window. Previously disclosed are so-called ventilation windows in the form of an internal panel and an external grille, although it is essentially necessary to provide an additional window-like construction alongside the ordinary window. It is necessary in this case either to increase the area occupied by the window and the ventilation panel to one side of it, or to reduce the size of the ordinary window. These represent respectively more expensive and less effective solutions to the problem.

The principal object of the present invention is thus, in the first instance, to solve the aforementioned problems by simple and efficiently functioning means. The aforementioned object is achieved by means of an arrangement in accordance with the present invention, which is characterized essentially in that an air admission passage is present along at least some part of the aforementioned frame and outer casement when the window, etc., is retained in the closed position, and in that arranged on the inside of the aforementioned window is a covering frame, which is preferably pivotally mounted, for respectively closing and opening the aforementioned passage.

An arrangement 1 for a window 2 or some other suitable covering element, which exhibits a window casement or other outer casement 4 intended for a covering element pivotally mounted and capable of being accommodated in a window frame 3 or some other frame, has an air admission passage 5 along at least one part, but preferably the entire peripheral part of the aforementioned frame 3, when the window 2, etc., is retained in the closed position I. Arranged on the inside 6 of the aforementioned window 2, i.e. internally in relation to the horizontally H or vertically V pivotally mounted window 2, is a preferably pivotally mounted covering frame 7, for example as shown in Fig. 1 and in other drawings. The aforementioned air admission passage is formed in this case by a gap 5 formed permanently between the frame 3 and the outer casement 4 when the window 2 is retained in the closed position I, at least along its one side A, but preferably all around the periphery A, B, C, D of the window and the frame.

A seal 8, 9, preferably comprising an inner 8 and an outer 9 seal respectively, is arranged on the aforementioned window arrangement 10, so that it seals between the outer casement 4, the window frame 3 and the covering frame 7 along the aforementioned air admission passage 5 in a position in which all the moving parts 4, 7 contained in the window arrangement 10 are moved to the closed position I. The aforementioned seals 8, 9 are formed preferably by compressible strips, either homogeneous or hose-shaped, which are capable of being accommodated with a fixing part 8A, 9A in matching grooves 11, 12 and which extend all along the periphery of the covering frame 7 and at a mutual distance X from one another and are suitable to make contact with a sealing part 8B, 9B close against the respective inward-facing 13 surface 3A and 4A of the frame 3 and the outer casement 4.

The aforementioned outer casement 4, which in the illustrative embodiment shown in the drawings in Figs. 8-20 is pivotally mounted about vertical pivot bearings 50 in the frame 3, preferably has the outer casement 4 and the covering frame 7 arranged in such a way as to be capable of connection to one another, so that the outer casement 4 is caused to pivot together with the covering frame when the latter is caused to pivot. The aforementioned function can be achieved, for example, by the arrangement of a number of guide pins 15 capable of being accommodated in grooves 14 so as to act between the outer casement 4 and the covering frame 7. See Figs. 9A, 12, 12A and 14. Arranged along at least the upper horizontally situated part 16 of the covering frame 7 is a guide groove 14, in which a guide pin 15 arranged on one upper corner 17 of the outer casement is capable of being accommodated and guided in such a way as to be displaced along the intended distance as far as a position in which it is disengaged from the aforementioned guide groove 14, as shown in Figs. 15 and 16, and in which position II the window, i.e. the outer casement 4 with its associated glass unit 18, is free to be caused to pivot around its bearing 14.

Illustrated in Figs. 1, 2, 24 and 25 are positions in which the window 2 with its outer casement 4 is pivotally mounted about a horizontal pivot 19 so arranged as to be capable of being caused to pivot around fully or partially when the covering frame 7 is pivoted upwards out of the way about its vertical pivot 20.

A turning handle 21, 22 is arranged for this purpose on the inward-facing 13 side of the covering frame 7 and/or the frame 3, which handle can exhibit a locking device 23 capable of actuation by turning so arranged as to be capable of being locked in the frame 3 and in the outer casement 4 in various desired locked positions.

Both the outer casement 4 and the covering frame 7 in this case are capable of exhibiting glass, 18 and 24 respectively, or some other covering element in sheet form, depending on the kind of covering element to which the invention is applied. The covering frame 7 is shown without glass in Fig. 8. The material in the component parts of the aforementioned window arrangement can be unmixed or a combination of wood, metal, for example aluminium, or a plastic composite material.

Explanations are provided below for a number of the aforementioned illustrations. Illustrated in Fig. 5 is the front of a window viewed at an angle from inside and with everything in the closed position I with the handle 21 facing downwards. In this position, the window casement is locked against rotation by means of double-acting bolt locks which enter into engagement with the casement and the frame respectively. On the opposite side, the covering frame is equipped with a hinge attachment to the window frame. The function is illustrated in section in Fig. 8. Fig. 9 shows the locked night ventilation position.

From here, the window is opened by turning the handle 21 to the horizontal position, and the covering frame "carries" the window casement with it via the pins 15 of the window casement and out to the night ventilation position, where the window is locked with the handle 21 and the bolts 25, 26 enter into engagement in position in the casement 4 and the frame 3, and the window 2 is now locked in this position I. The locking handle 21 can be supplemented, if necessary, with a cylinder lock. The function is illustrated in section in Fig. 9A. Figs. 12, 12A, 13 and 14 show a so-called "child safety position" or a wide ventilation position in perspective and as a sectioned view. For this purpose, the handle 21 is turned to the horizontal position from a window 2 that is closed or open for night ventilation, and the covering frame 7 / window casement 4 is opened. The casement 4 accompanies the covering frame 7 via the pins 15, which are in engagement in the guide grooves 14 of the covering frame 7 at the top and at the bottom. The connection of the window casement 4 to the covering frame 7 means that a distance is formed between it and the window casement 4, the purpose of which is inter alia to prevent the window casement from "gnawing" on the sealing strip 8, 9. The sliding motion of the window casement 4 in the guide grooves 14 is arrested by a heel 27 in the upper guide groove 14, and it is prevented from shutting of its own accord by a spring 28, which is positioned in the upper guide rail 14 in front of the child security stop. The function is illustrated in section in Fig. 12A.

The outer casement 4 is centre pivot-hung on the frame, for example at the top and bottom, on pins. The casement 4 has indentations for a turning lock arrangement in two positions and spring-assisted insertable combined guide pins and child safety pins at the top and bottom on the lock side and diagonally for the same function in the case of an inverted window. These pins enter into engagement automatically in the grooves in the covering frame when the window is closed. Finger grips for releasing the upper guide pin when disengaging the child safety function for the purpose of opening the window to the wide ventilation position are provided, and double finger grips are also provided for disengaging the lower pin for the purpose of opening the covering frame when inverting the window. Figs. 12A and 13 show the maximum opening of the window in the position connected with the covering frame 7. In conjunction with this, the window 2 is manoeuvred in the same way as when opening to the "child safety position", but when the window reaches the stop in the guide rail 14, the release mechanism 28, executed as a finger grip with two heels, recessed into the end wall of the casement and attached to the spring- assisted guide pin of the window casement, is actuated. In conjunction with this, the upper heel is pressed downwards, the upper guide pin is released from the child safety stop, and the window can be opened to its maximum opening. The outer casement 4 and the covering frame 7 are still connected to the guide pin 15 in the lower guide rail. Once the movement of the window has progressed past the child safety stop, the finger grip is released and the upper guide pin again enters into engagement in the upper guide rail. The child safety function engages automatically when closing the window from its maximum open position. The window can also be opened further, if required, for example as illustrated in Figs. 15 and 16. When operating the window in the opening alternative described above, the covering frame 7 and the window casement 4 are linked together at all times, which means that the covering frame, which does not contain any glass, does not exhibit any tendency to "flap". The function is also illustrated in section in the drawings. Fig. 16 illustrates a position for inverting the window. The window is placed in the child safety position in this case, after which the two heels in the opening mechanism on the end wall of the casement are drawn together with a double finger grip (two fingers) . In conjunction with this, both the upper and the lower pin are drawn in, and the covering frame is released from the window casement and can be swung out, so that the window casement can be fully inverted freely. In conjunction with reclosing, the guide pins return automatically into engagement once the window has been closed and the covering frame lies parallel with the window casement. The function is illustrated in section in Fig. 16. This construction permits vertical or horizontal hanging. A restriction in the size of the windows that can be manufactured is determined by the size of the glass units that can be produced. In the case of display windows, for instance, which are not ventilated but are only inverted on a few occasions per year, for example, the covering frame can be secured instead with advantage by the use of screws to enable them to be opened constantly.

A closed window 2 is illustrated in Fig. 17. In conjunction with both horizontal hanging and vertical hanging, 5 the handle is positioned on the side of the inner frame with a standard cremone bolt which locks the inner frame and the window casement on both sides at the top and respectively at the top and the bottom.

Fig. 18 shows the window in the night ventilation .0 position. Here the inner frame 7 is opened slightly, while the window casement 4 is locked. Ventilation 51 is obtained through the gap 5 between the casement 4 and the frame 3.

Fig. 19 shows the window 2 in the ventilation position. The window is opened by turning the handle to the open L5 position and pushing the window casement outwards into the inversion position. The inner frame 7 in this case can have a stop which prevents further opening. In conjunction with closing, the inner frame 7 is hinged back towards the frame 3 and is locked, which also locks the window casement 4. 0 Fig. 20 shows an inversion position. The window 2 here can be rotated without obstruction in the desired direction of pivoting 52, 53.

The invention is naturally not restricted to the embodiment described above and illustrated in the accompanying 5 drawings. Modifications are possible, in particular with regard to the nature of the different component parts, or by the use of comparable technologies, but without for that reason departing from the scope of the protection afforded in the Patent Claims.
