The present invention relates to a closure fasteningdevice, by means of which it is possible, without touchingthe window pro er, to place the same in a more or less open position for the purpose of ventilation.

An embodiment is described below with reference to the accompanying drawings in which the invention is shown applied to a windowof the type mounted to pivot about. a horizontal central axis.

In these drawings:

nism. i

To thebottom piece of the frame a device is fastened comprising a gear wheel 3 mounted to be rotated on a vertical shaft 2, said gear wheel being fixedly connected to an operating arm 4 and'engaging' two rods ,5, B, one of which, 5, is positioned at the edge of the gear wheel facing outwards, while the other one is positioned at i the inside. The rods ,5, 6 are twisted and bent in the way illustrated in Figures 1 and 2 and extend from the centre of the bottom piece of the frame towards the ends thereof. In Figures 1 and 2 just one of said rods is completely shown. At some distance from the gear wheel 3, the rod 6 is provided with a projecting pin 1, extending through a slot 8 of a cover or sleeve 9 enclosing the mechanism. I

To the bottom edge of thewindow-sash ill a plate II is secured opposite the pin 1, said plate I i being provided with .a slot 12 of the configuration shown in Figure 1 1. The width of said slot is such as to allow the pin 1 to be freely displaced therein. In some cases the slot I2 is of a zigzag-line conf guration, as indicated in Fig. 12.

tudinal recess I4 housing a vertical tube l5, as shown in Figure 1a. Said tube I5 is provided at its lower end with a horizontal arm l6, and said lower end of the tube is positioned in an opening in aplate ll on the bottom piece of the frame. The arm 16 is provided, at the free end thereof, with a vertical pin l8 engaging aslot [9 of a rod 2!] connected in turn with the rod 6 by means ofa sleeve 2|. Said sleeve 2i encloses the two rods 6, 20 at a portion thereof'provided with

teeth

22, 2 3 in the, surfaces thereof facing each other, said teeth engaging each other. The arrangements in connection with the rod 5 are of the same nature as those described above in connection withthe rod 6.

In the position of the device shown in Figure 1 the window is opened to such extent as to place the open inner end of the slot I2 at the pin 1. When turningthe operating arm 4 is a clockwise direction from the position shown in Figure 1, the arm 6 is pulled to the'leftin Figure 1, the pin 1 thereby sliding on the left-hand edge (Figure 11) of the slot I2, thus forcing the lower part of the window-sash inwards. This continues until the pin 'l'enters the outer portion [2a of the slot 12, said portion 12a being parallel to the bottom piece of the frame, and the window-sash then occupying its closed position.

Meanwhile the pin 8 of the arm It has been displaced within the slot [9 and at thesame time said pin It has been swung in a clockwise direction (Figure l). Simultaneously the tube 15 is turned somewhat in the same direction, and during the movement of the pin '1 in the portion l2a of the slot said tube is pressed against the window-sash Ill so as to create a complete tightening between the frame and the sash.

The upper end of the tube 15 is conveniently inserted in an opening in the top piece of the frame, and as mentioned before, the lower end of saidtube is positioned in the opening of the arm i6 and plate I! but without being fixedly connected to either. By lifting the tube 15 so as to pull it out of the opening of the arm l6 and then moving it obliquely downwards from the t p piece of the frame, said tube is easily removed from its position in the frame, this being of importance, as, for instance, when painting.

By the device shown, including

toothed rods

8, 20 and the sleeve 2| interconnecting said rods. the total length of the rodsis readily varied.

The invention is not limited to employment in windows of the type described but is also advantageously applicable on windows of other types, e. g. windowsadapted to pivot about a vertical axis. Thereby, in certain cases, the tightening tube l5 and the parts nearest connected therewith are superfluous or cannot be utilized advantageously. The invention is not either limited to the construction of details shown in the drawings but all equivalents are also included in the protection.
