Description

In the case of double windows and doors, a type of tight lock is known in which the two leaves are shifted against each other in a vertical direction. Here, the tight seal only occurs at the lower edge, while the other three edges are more or less free in the frame.
The subject of the invention is a double window or a double door, in which the four edges slide into folds of the frame when closed and consequently bring about a tight seal on all sides. This is achieved by moving the sashes against each other in a diagonal direction for the purpose of opening and closing, which results in an enlargement of the window or door area as a result of the expansion and a reduction in size by moving in the opposite direction. The edge emerging from the surface all around when it is spread is pushed into the folds of the frame so that the window or door is now locked all around and sealed off;

The connection of the two wings, which enables this movement, is done appropriately in such a way that head bolts at the corners of one wing in the rectified, Slidably above the recessed slots of bearing plates that slide on the other wings are arranged accordingly, whereby both wings are held against each other and are guided. You can after uncoupling the connecting the two wings Hand lever or the crank pin are moved against each other until .the Head studs get into the area of the recesses that prevent the two from becoming detached Allow wings from each other.

Γη of the drawing is shown an embodiment of the subject matter of the invention.

Fig. 8 is a cross-section through the junction of the two wings.

The double window consists of an outer wing α and an inner wing b. On the latter there is a hand lever e, the crank pin e ^{1 of} which engages in a bearing plate f attached to the outer wing α. At the

outer wing α four head bolts c are also attached, which slide in the slots c ^{1 of} the corresponding bearing plates d of the inner wing b and hold the two wings together by their overlapping heads. The slots c ¹ in the bearing plates d have a uniform inclination and each end at the top in a recess c ² , which is larger than the 'head of the

ίο head bolt c so that it can be passed through the former.

There are folds in the window frame. When the window is open, the hand lever e is up. If it is moved downwards by turning, the crank pin e ¹ presses the outer wing a, which is guided in the diagonal direction by its head bolts c in the slots c ¹ , first downwards and sideways into the corresponding folds of the window frame in which it is located sits down firmly. With the further rotation of the hand lever e , the inner wing b is then supported against the outer wing α and is thereby pressed obliquely upwards in the opposite direction into the upper and side folds. If the inner wing b, as usual, is attached to the window frame so that it can pivot by fish straps, these are designed accordingly to allow the wing to move in an oblique direction by z. B. are provided with slots in which the pegs connecting the fish straps to the wing can slide according to the diagonal movement of the latter.

When unlocking the window to open it, the process is repeated in reverse

- the other way around, in that the inner wing b first moves downwards and to the side and the outer wing ο then rises and at the same time moves back out of the fold on the other long side.

In order to be able to separate the wings from one another for the purpose of cleaning, it is necessary to temporarily disengage the crank pin e ¹ , the eccentricity of which determines the amount of displacement of the two wings relative to one another. This can be done, for example, in such a way that the hand lever with the crank pin e ^{1 is} pulled out of the door so that it goes free from the same. The inner wing b is in its lowest position when the window is open. After pulling out the crank pin e ¹ , the outer wing can then be raised so far that its head bolts c get in front of the recesses c ^{2 of} the bearing plates d . Since the heads can pass through the openings, the outer wing α can be lifted off the inner wing b in this position.

Claims (3)

Patent claims: 1. Double window or door with wings which can be displaced relative to one another by hand levers on their connecting means, characterized in that the wings (a, b) can be moved in opposite directions in a diagonal direction. 2. Window or door according to claim 1, characterized in that at the corners of a wing (α) head bolts (c) and at the corners of the other wing (b) the head bolt receiving bearing plates (d) with rectified and upward to a Recess (c ² ) enlarged oblique slots (c ¹ ) are arranged. 3. Window or door according to claim 1, characterized in that the hand lever (e) with crank pin (e ¹ ) serving to move the two wings against one another can be pulled out of the door or window. 1 sheet of drawings
