1 to create 2 for windows, which are also in fixed claims: frames with a low overall height can be installed in a simple manner. 1. Ventilation for windows with a transverse This object is cut according to the invention box-shaped, fixed frame with 5 solves that as a means to shut off one of the two concealed ventilation slots in front of and ventilation slots on the one behind the glazing the glazing in the wall of the fixed frame adjacent to the glazing Wall of the box is mounted in cross-section slidable, and that the ventilation slots migen, fixed frame and with means interrupting webs in this wall of the festzum Shutting off the air flow, thereby io standing frames are arranged. Through this characterized in that as a means of remedial action, the task at hand is simple lock one of the two ventilation slots (4, 5) means released and achieved that the door in the Querauf the wall of the box-shaped, fixed frame adjacent to the glazing fixed frame (3) a plate (9) on one wall of which the ventilation slots are recessed • Is slidably mounted, and that the ventilation 15 are, a normal frame profile with the slots (4, 5) interrupting webs in this usual height can be used.
Wall of the fixed frame (3) arranged ■ It is common practice for ventilation systems to be ventilated. through slots. slidable plates 2. Ventilation according to claim 1, characterized in that these known ventilations have the pre-characterizing that, however, do not suggest that to achieve an easy-going 20 standing arrangement and finely adjustable ventilation placed the plate (9). displaceable at an angle of about 45 °. An embodiment of the invention is shown in FIG is. Drawing shown and described below, it shows 25 'Fig. 1 shows a section through the fixed frame a sliding window with ventilation, The invention relates to a ventilation system for windows with FIG. 2 the ventilation in plan view, a stationary In F i g that is box-shaped in cross section. 1 are the two sliding frames Frame with concealed ventilation of a sliding window with 1 and 2 and the fixed slots in front of and behind the glazing in the frame in FIG. 30, denoted by 3. The fixed glazing adjacent wall of the cross-section frame can be along its entire length box-shaped, fixed frame and with or in sections with two parallel means to shut off the air flow. len rows of ventilation slots 4, 5 be provided, In a known ventilation of the specified type, of which the outer row is fitted with a filter (French patent specification 1 218 392), the fixed strip 6, for example made of flywire, is made up of closed frames composed of several parts. The filter strip 6 is inserted into the grooves 7, 8 and a relatively large space can be pushed. The ventilation slots 5 of the other row for the passage of the ventilation flow from one are, as also the F i g. 2 shows, with a plate 9 ventilation slot to the other ventilation slot pre-covered, which are inclined to the longitudinal axis in itself. This air flow can be displaced in a manner known at its 40, wherein a screw; The flap held at the top can be locked. at the same time the fastening and guiding of the plate. Even in the open position (see FIG. 3), however, it must serve. Due to this type of displacement, the air flow is a narrow, exposed below the flap, the cross-section of the ventilation slots 5 for the left gap to pass. However, this has the effect of utilizing almost 100% of the air passage,
Known ventilation with a further, arranged in the opposite direction through the ventilation slots 4 and through the ventilation slots 4 and the air always at the top of the air penetrating the ventilation slots 5 into the room and proportionally consists of the opposite wall of the transverse large flaps are regulated by the air flow. cut out box-shaped, fixed frame 3 It is regarded as a disadvantage that this venting, which is a cover plate 10, which has an approximately U-shaped design, cannot be inserted independently of the weather and with its bevels 11 can be placed in the grooves 12 of the and that the known fixed webs 13, 14 can be pushed in. Frame because of this relatively large folding When the panel 9 is open, the air can be independent pen must also have a large overall height. From the position of the displaceable frames 1, 2, there is the task of a concealed ventilation 55 penetrating through the gaps 15, 16.
