Tilt window

The invention relates to a tilt window. In the case of such windows, the sashes or sash frames are on their upper or lower edge for opening and closing an angular movement of the window rotatably mounted about a horizontal axis.

409841/0331

Such windows are safe and satisfactory in terms of handling and operation. However, you can from the outside cannot be cleaned, and this is a disadvantage if such windows are on the upper floors of a building are built in. In this regard, windows of this type are unfavorable compared to so-called "swing through" windows, in which the window sash is hinged horizontally pivotable between its upper and lower end and by 90 or 180 ° can be pivoted to a position in which the inside is outside in order to clean the outside. With such windows it is however, in order to avoid accidents, it is essential that the movement of the window sash can be easily controlled, and that the Window sash remains securely in any angular position in which it was set.

The invention is therefore based on the object of providing a window which is satisfactory and safe in operation, and in which the window sash can easily and safely be brought into a position for cleaning the outer surface of the window.

This object is achieved in a tilt window of the type mentioned in that the window sash at one end of a Part of a subframe is hinged horizontally pivotable, which in the fixed window frame or a part attached to the same between the upper and lower ends of the same is horizontally pivotably mounted that a retractable locking device for locking the part of the sub-frame is provided substantially in the same plane as the fixed window frame, and that the fixed window frame and the Sashes are each coupled with a connecting piece that is used to hold the sash in both a ventilation position as well as in a completely or partially inverted position is effective when after retraction of the locking device the part of the subframe is rotated out of the plane of the fixed window frame.

Preferably, the subframe with the window sash is 180 degrees rotatable to an inverted position, and the connector is substantially J-shaped with its curved portion below of the articulation point of the part of the subframe is arranged when the window sash is in this inverted position is located.

Fig. 9 is a section along the line C-C of Fig. 5, and FIG. 10 shows a section along the line D-D of FIG. 5.

In the drawing, a square window with a fixed window frame 1 made of wood is shown. On the outer surface of the fixed window frame, e.g. by means of screws, the upper half or the upper part 2a of a subframe 2 is fixed, which essentially consists of a T-profile made of an aluminum alloy is made. The lower part 2b of the subframe is with a horizontal axis of rotation 3 attached to the upper half 2a, and at the lower end of this subframe is the lower end of the actual window sash frame, here called window sash 4 for short, which also consists of an aluminum alloy, hinged horizontally on each side with pivot pins 5. Seals 6 and 7, for example made of rubber, are between the flange parts of the upper and lower parts 2a, 2b of the subframe and the fixed one Window frame 1 on the one hand and the window sash 4 on the other hand.

The fixed window frame 1 and the window sash 4 are on each side with a stabilizing, substantially J-shaped Connector 8 articulated. The shaft end of this connector has a slot 8a with which it is hingedly attached to the window frame 1, while the hook-shaped end of the connector is hinged to the window sash 4.

It is to be explained that the upper part 2a and the lower part 2b of the subframe do not have the same T-shaped cross section. The upper part 2a has flanges which have clearly unequal widths, so that a special scope for the working movement of the connecting piece 8 can be provided on one side, while the lower part 2b flanges with only a small difference in width having.

Each hollow side part of the lower part 2b of the subframe contains a locking mechanism that can be activated by turning a

409841/0331

corresponding one of a pair of front-accessible handles 9 is operated. Each of the handles 9 is coupled in some more or less conventional manner to cause vertical movement of an actuating rod 10 of substantially I-shaped cross-section, which is slidably received within an elongated channel of rectangular cross-section in the window sash 4. Each actuating rod 10 is provided with three laterally projecting away pivots 10a _f TOB and 10c, which project slidably through slots 4a, 4b and 4c in the side of the window sash. 4

The locking mechanism also includes a slotted and slidable pin 12 on each side of the window Latch 11 near the lower end of the lower part 2b of the subframe. Fig. 9 shows the bolt 11 in its locking Position in which it protrudes into an opening in the window frame 1. The bolt 11 has a recess 11a on one side edge, in which the lowermost pin 10c of the actuating rod 10 is arranged. The same side edge also has a step 11b for receiving it of the pivot 5.

So that the window sash 4 on the entire subframe 2a, 2b when the window is to be closed (Fig. 6) and on the actual, The lower frame can be locked if the window sash is only to be turned over (Fig. 3 and 4), the lower one has Frame part has a recess 14 for receiving the pin 10c, while the lower frame part on its side edge has a T-shaped slot 15 and a rectangular recess for the corresponding Has receiving the pin 10b and 10a. The window is operated as follows:

The components of the locking mechanism of the window have three positions, shown mainly in Fig. 6 in dashed lines and denoted by X, Y and Z. The positions X correspond to the closed window, the positions

409841/0331

Y the window open for ventilation and the positions Z dem for cleaning upturned window sash. So the handle 9 is with the window sash closed (Fig. 1, 6 and 9) vertically directed downwards und.has pushed the actuating rod 10 completely down, whereby the bolt 11 over the pin 10 is engaged with the window frame 1. The lower part 2b of the subframe is thus locked to the window frame, and the window sash is locked to the subframe via the pin 10a or 10b of the actuating rod, which is connected to the slots 15 or recess 16 of the subframe are in engagement. The J-shaped connecting piece 8 is substantially vertical and is out of order.

The handle is used to open the window sash for ventilation rotated 90 ° to a horizontal position, the operating rod 10 is raised a short distance. These However, movement of the operating rod is insufficient to lift the bolt 11 out of engagement with the fixed window frame 1, so that the part 2b of the subframe remains locked with this. However, this movement of the operating rod is sufficient to the Pins 10a, 10b and 10c from the locking engagement with their associated recesses or slots 14, 15 and 16 (position Bring YJ so that the sash 4 is around the pivot 5 can be tilted into the position shown in FIG. 2, the connecting piece 8 exercising its holding function.

To turn the window sash 4 for cleaning, the handle 9 rotated 180 from a vertically downward position to a vertically upward position. This movement of the handle raises the actuating rod 10 as far as possible, so that the pin 10c removes the bolt 11 lifts the locking engagement with the fixed frame and the pin 10a is brought out of the recess 16. The cone 1Ob remains lockingly engaged with the T-shaped slot 15, however, and consequently the window sash 4 still remains with the

lower part 2b of the subframe locked, but no longer with the upper part 2a of the subframe, and can be accessed via the in Pivot the position shown in FIG. 3 into the inverted position shown in FIG. 4, in which the lower part 2b of the subframe opposite the fixed, upper part 2a of the subframe lies. The hook-shaped end of the J-shaped connecting piece 8 is then directly below the axis of rotation.

It can be seen from Fig. 3 and 4 that if the handle 9 is accidentally moved into a position Y, which the window sash 4 would effectively unlock from part 2a of the subframe, the connecting piece 8 only a very short fall of the window sash 4 would allow.

The resetting of the window flight ice 4 in the ventilation or The closed position of the window is achieved by reversing the movements and activities described above.
