Description

The additional patent 959 441 relates to a lifting and pivoting casement window with a central ' horizontal axis swingable, liftable by means of a device over a lower sealing strip and Lowerable wing with bearings consisting of one attached to the linkage of the lifting device and one attached to the wing Half and consist of a bearing pin connecting the two halves, one of the two or both bearing halves attached to the wing od several notches on their collar. have, of which one when lowering the wing with the upwardly directed cutting edge one Extension arm attached to the frame comes into engagement in such a way that the wing is in the respective Is held in the open position.

With this type of pivoting casement window it has been found that in most cases it is useful to have another facility is provided, which enables the raised sash in a certain opening position, for example, after a pivot of about 30 °, to hold without the open for this purpose Wing must be lowered. The invention relates to such a device. They can be disengageable or also be set up so that they are when pivoting back or when pivoting the wing triggers automatically. It is sufficient if such a device is provided on only one warehouse.

Windows have already become known in which the sash can be pivoted about a central axis is and can be locked in a certain open position and with one between the bearing halves Locking device is provided, which consists of a screw bolt provided with a handle, whose axis is parallel to the axis of rotation of the wing and the wing by pivoting the handle of Hand can be determined or released again at will. This facility has the disadvantage that the locking of the wing does not take place automatically and can only be done by hand.

Next, windows with a central axis of rotation are known in which a under the action of a provided in a removable housing coil spring standing locking bolt so adjusted can be that it engages in a provided in one of the two bearing halves hole and on this Way the bearing half in which the housing is located, and thus also the wing in the desired Holds open position. This design has the disadvantage that for guiding the locking bolt and a special housing must be provided to accommodate the helical spring, whereby the production of the pivot bearing becomes unnecessarily expensive.

The aforementioned disadvantages occur with the article of the invention does not occur.

The object of the invention is shown in the drawing, for example. It shows

Fig. 1 a locking device according to the invention in section, in the position of two bearing halves that they occupy after the desired pivoting of the sash,

Fig. 2 shows the position of a locking pin when the sash is not swiveled out, i.e. when it is closed Wing,

Fig. 3 is a section along the line AA of Fig. 1, in which the bearing half in which the locking pin engages has a recess extending obliquely to the end face from the bore in which the locking pin is engaged, through which the locking pin comes out of engagement with the bore when the wing is suddenly pivoted, and the

Fig. 4 shows a section along the line BB of Fig. 3. In the drawing, the same reference numerals have been retained for the two bearing halves and the bearing pin as in the additional patent 959 441. The bearing half c is attached to the casement. The other half of the bearing i is under the action of the linkage of the lifting device. The two bearing halves c and i are rotatably connected to one another by a bearing pin d. In the bearing half i , a locking pin ο is slidably mounted in a bore m, which is provided in the side facing the bearing half c , which is under the action of a helical spring η and always tries to move towards the bearing half c . In the latter, the release pin q is slidably mounted in a bore on the side facing the bearing half i. This is connected by means of a pin s ¹ to a push button s which can be pushed into a bore t. The bore is located in that of the bearing half i

facing side of the bearing half c provided. The pin is under the action of a helical spring r in such a way that it always tries to move out of the bore t until the release pin q has found a stop in the bore p. The holes m and p are arranged in relation to one another so that they are opposite one another after the wing has been pivoted.

In the embodiment according to Figs. 3 and 4, the bearing half c has next to the bore p a recess u which runs obliquely to the end face and via which the locking pin o moves back when the wing is moved back to its original position by force.

The mode of operation of the device according to the invention is the following:

When the wing is pivoted into the intended open position, the locking pin ο automatically snaps into the ao hole p of the other bearing half c when it reaches the open position due to the action of the helical spring η until it rests against the release pin q in the other bearing half c comes so that the wing is held in this position. If the wing is to be swiveled out of this position, the locking pin o is to be pushed back out of the hole p by pressing the button ί against the action of the helical springs η and r , so that the wing can then be swiveled again.

When implementing the device according to Figs. 3 and 4, a short jerk on the lower transverse spar of the wing is sufficient to release the locking pin 0 through the sloping recess u .

It goes without saying that such locking devices can also be provided at several successive points so that, for example, the wing can be locked in open positions of 15 °, 30 °, etc., if necessary up to 90 °, in which case an inclined recess u on each hole p can be provided in the direction of the further pivoting movement, so for the forward and backward pivoting.

Claims (3)

PATENT CLAIMS: 1. Lift and swing casement window with a pivotable about a central horizontal axis, can be raised and lowered by means of a device via a lower sealing strip and with bearings consisting of a half attached to the linkage of the device and a half attached to the sash and one of the two There are bearing bolts connecting halves, one of the two or both of the bearing halves attached to the wing having several notches or the like on its collar, one of which comes into engagement when the wing is lowered with the upwardly directed cutting edge of an extension arm attached to the frame, according to the additional patent 959 441, characterized in that the non-rotatable bearing half (i) attached to the linkage of the lifting device on the side facing the bearing half (c) attached to the wing and rotatable together with it, one parallel to the axis of the bearing pin (d) has attached hole (? ») in which a coil spring (» ) standing locking pin (0) can be pushed in such a way that it automatically snaps into a hole (/>) provided in the rotatable bearing half (c) when the opening angle of the wing determined by the position of the hole (m) is reached. 2. Window according to claim 1, characterized in that a release pin (q) is slidably mounted in the bore (/>) of the rotatable bearing half (c) and is connected to a push button (s) through the intermediary of a pin (s ¹ ) , which protrudes from the rotatable bearing half (c) on the side facing away from the non-rotatable bearing half (i) and is under the action of a helical spring (r) provided in a bore (i) of the rotatable bearing half (c), whereby through the push button (s) - against the pressure of the helical spring (ti ) lying in the non-rotating bearing half (i) - the locking pin (0) can be pushed out of the hole (ρ) with the help of the release pin (q) , whereby the wing for the further panning is enabled. 3. Window according to claims 1 and 2, characterized in that the rotatable bearing half (c) has a recess (κ) directed radially to the axis of the bearing pin (d) and extending from the bore (p) obliquely to the end face which the locking pin (0) can be brought out of engagement with the bore (p) when the sash swings abruptly.
