Device for lifting the window sash parallel to the casing frame in a gap-wise ventilation position

Patented in the German Empire on September 15, 1931

The invention relates to a device which is used in casement windows and outer casement doors lifts the sash parallel to the casing frame in a gap-wise ventilation position and it moves diagonally downwards when closing, so that it moves by its own weight all around by means of its stop surfaces without tension and rainproof.

The purpose of the invention is to create a window which, in addition to the exposure and Ventilation of the interiors in a known manner still a permanent ventilation through a gap Position of the wings to the feed frame allows rain to penetrate the Excludes interior spaces, and which, when closed, provides permanent security against drafts and the ingress of rain, even when there is wind, at the same time but also prevents jamming of the wings.

Windows are already known which have a gap-wise ventilation position of the sash have parallel to the feed frame, but this known embodiment only allows A nice weather ventilation, because with it the rain can penetrate unhindered into the interior can, whereas with windows according to the invention the sash position achieved by this all rainwater safely drains to the outside and thus a permanent ventilation of the Indoor spaces permitted in all weather conditions.

Windows and doors are also known where the window is sealed the wing is pressed against the lining frame by its own weight. the In these known embodiments, however, there is always only one contact pressure The stop side of the wing takes place and leaves the tight seal of the other stop surfaces of the wing out of consideration, whereas the subject of the invention is a pressing of the Wing caused by its own weight all around on its stop surfaces and thereby Safe protection against drafts and rain penetration all around on all sides of the wing and also in the event of wind.

The invention solves this problem in a perfect way in that the wing is attached to the feed frame with flexible fish straps in such a way that it takes off its closed position by means of parallel link pairs that can be expanded obliquely upwards of the fish tape mandrels carrying the wing in conjunction with a push-off eccentric at an angle raised upwards and parallel to the feed frame into a gap-wise ventilation position becomes and when closing by its own weight "the reverse movement obliquely runs downwards and parallel to the feed frame. The free wing side is here by a known institution

matching with the stop side also guided parallel to the feed frame, so that When closing, the sash is firmly against all stop surfaces due to its own weight presses on. The gap-wise ventilation position in which the wing is raised by the subject matter of the invention is chosen so that in this position against the wing beating rain ίο on the outside of the feed frame and so that it is safely diverted to the outside. The ventilation position is just like the closed position Can be locked in a known manner and is therefore safe to enter. In the unlocked -15 gap-wise ventilation position, the sash can be fully opened inwards in the usual way and be returned to the former again. This is made possible by the fact that the eccentric is designed circular in its moved by the swinging wing outer part, whereby the fish tape thorns remain in the raised and splayed position in the ventilation position. In the drawing, the object of the invention is shown, namely show Fig. Ι a horizontal section through the window with the push-off device, Fig. 2 is a vertical section through the window with the one-dotted gap Ventilation position of the sash, Fig. 3 is a side and a front view of the resilient fish straps and Fig. 4 is a front view of the push-off device. The fitting to be attached to the wing 4 and to the lining frame 8 consists from the flexible fish straps, the strap part of which is attached to the feed frame 12 by means of the parallel link pairs 13 the spreadable Fish tape mandrel 11 carries, on which the hinge part attached to the wing 10 is rotatably pushed on, as well as from the push-off device with the on the Wing 4 rotatably hinged about the mandrel 2 lever 1, which by means of the push rod 3 the eccentric 6 moves, which is rotatable by the belt 5 around its mandrel 7 on the The sash frame 4 is attached and presses against a pressure plate 9 on the casing frame 8. In addition to these fittings belonging to the invention, the wing still gets through known fitting parts a concurrent guide on the rising wing side, a Lock for the gap-wise ventilation and the closed position as well as the usual corner brackets. In order to raise the wing into the gap-wise ventilation position, the lever 1 is turned, which then rotates the eccentric 6 about its eccentric part α through the push rod 3 and thereby pushes the wing 4 off the feed frame 8 and simultaneously through the spreading of the parallel link pairs 13 and the fish tape 6g thorns 11 obliquely upwards from its rising seating surfaces in the direction of the arrows R in FIG. In this raised position, the wing can be pivoted inwards in the usual way be, wherein the eccentric 6 is rotated with respect to the chuck frame 8 further about its Teilö, which thereby its circular design keeps the wing in the raised position. The window is closed by reversing what was done when it was opened Movements, whereby the dead weight of the wing comes into effect and it all around presses firmly against its stop and seating surfaces. Patent claims: i. Device for lifting the window sash parallel to the casing frame into a gap-wise ventilation position, characterized by a push-off cam (6) which is attached to the casement frame (4) and is supported against the casing frame (8) and rotatable by means of a lever (1) and a push rod (3), furthermore by flexible fish straps (ία, ii, 12), whose mandrels (11) carrying the window sash (4) can be spread obliquely upwards by means of parallel link pairs (13) from the fixed strap parts (12) attached to the feed frame (8), and finally by sloping upwardly rising seating surfaces (arrows R, Fig. 2) on the lower and upper transverse legs of the sash frame (4) and the feed frame (8), which in conjunction with the push-off eccentric (6) and the obliquely upwardly expandable fish tape spikes (11 ) cause the window sash to experience a slant upward movement parallel to the casing frame when opening a gap. 2. Apparatus according to claim 1, characterized in that the Abrückeccenter (6) besides its actual eccentric part (ß) for lifting the window sash (4) from the lining frame (8) still has a circular part (b) which is used when complete opening or pivoting of the window sash around its fish tape mandrels (11) no longer change the gap-wise opening position previously achieved by the eccentric part (a) during the entire pivoting movement of the sash. 3. Apparatus according to claim i, characterized in that due to the inclined, lower and upper on the sash frame (4) and on the feed frame (8) located Aufsitzflächen and the oblique upward movement of the fish tape mandrels (11) when closing the window sash an obliquely downward movement of the wing takes place so that it presses itself against its stop surfaces without tension and rain-tight by its own weight all around.
