LT4631B - Window with ventilation louvre mounted in a swinging manner in the fitting groove of the casement - Google Patents

Abstract

In a window comprising a frame and a leaf and means for permitting forced ventilation in the closed state, the forced ventilation path extends over a fitting groove (21) in a horizontal casement leg, a ventilation louvre (4) being fitted such that it can swing in the fitting groove. In its rest position, the ventilation louvre (4) allows air to circulate through the fitting groove, but when greater flow pressure acts on the louvre it is deflected into a position which throttles or blocks the passage of air.

Description

It is known that in modern windows with very tightly closed sashes and also with closed windows, the ventilation possibility created by the ventilation means in the windows must be left. When the windows are made of plastic or aluminum, ventilation is provided between the outside and inside of the window thanks to the boreholes located inside and outside of the sash frame profile, which allow air movement through the solid frame profile chamber and through the holes in the chamber walls. When the windows are wooden, the ventilation bridge is built into the frame bridge.

v

These known ventilation devices have the disadvantages of producing undesirably difficult and erratic air movement under defined conditions. For example, in strong winds, incoming air creates unpleasant drafts, or when it is cold and causes a large difference in outdoor and room temperatures, the very warm air in the room is blown into the field, and in the case of windy air is amplified and can influence unwanted heat loss.

The object of the invention is to provide improved ventilation means which are used in windows and, when the windows are closed, provide the necessary artificial ventilation or, under appropriate weather conditions, prevent excessive air exchange. It goes without saying that ventilation must be reliable and simple.

This task at the level of the invention is mainly set forth in the first claim of the invention and in the subsequent claims the automatic installation of a vent in the groove of the horizontal frame elbow.

An example embodiment of the invention is described in detail with reference to the accompanying drawings. The drawings show:

FIG. 1. Transverse section through the lower elbow of the window frame and sash.

FIG. A sectional view of a section of a lower sash frame elbow frame with a ventilation system according to the present invention.

3. An aerial view of the ventilation system with its retractable mounting elements for mounting in the groove of the elbow frame.

FIG. Increased cross section of the vent.

FIG. 5. An enlarged cross-sectional view of the ventilation system constructed in accordance with the present invention through a sectional and sash frame in the region of the groove.

FIG. Section 1 shows a horizontal lower elbow (1) of a single frame and a horizontal lower elbow (2) of a sash frame with an insulating fiberglass ring (3) inserted. An automatically operating vent (4) is movably mounted in the groove (21) of the profile frame fitting of the sash. FIG. Figure 1 illustrates a possible situation in this area. Figures 2 and 3 show in greater detail the installation and securing of the vent (4) in the fitting groove (21).

The longitudinal planar ventilation vent (4) is executed as an axially arranged vent casing which moves in a longitudinal direction in the groove of the hardware. The ventilation duct (4) is held along its two ends by means of mounting blocks (5), so that it is placed in the groove of the hardware and is secured to the elbow of the sash frame by means of a screw (6) and has support nuts (51). the ends of the vent. The mounting pads are like end walls which complete the section of the groove separated from the ventilation duct and the chamber formed by the ventilation duct on both sides of the ventilation duct and prevents the flow of air.

As can be seen from FIG. 1, the ventilation circuit visible in the bay region of the separate frame-sash combination passes through the groove (21) of the hardware. A bracket groove (21) for flow communication through a borehole or recess (22) with a plane (23) on the outside of the sash frame profile that interacts with a snap-on tongue (11) on the elbow (1) of the seperate frame. The boreholes or recesses (22) are, of course, disposed above the clamping tab (11). Exterior and interior gap areas A and B visible through a closed window, comprising interacting profile areas from the cavity area of the separate frame elbow and the sash frame, the borehole or notch (22), the clamping groove (21), and the other cavity space between A separate frame and sash frame may provide a ventilation path when the window is closed.

The operation of the ventilation duct (4) is clearly illustrated in FIG. 4 and 5.

FIG. 4 is a cross-sectional view through a vent (4) consisting of a beam (41), a lower portion (42) with a drilled hole for a support (43) and a bushing (44). The bushing thickening (44) is arranged such that with respect to the location of the drilled hole for the support (43), the bar (41) is opposite each other and this thickening forms a counterweight to the bar (41).

The angular expansion of the bushing thickening (44) and its thickness are calculated so that the ventilation air vent (4) in the resting state shown in FIG. 5, occupies a diagonal position which is the equilibrium position. The ventilation duct (4) is so mobile that it is easily moved out of its dormant position by the force of the current. Selecting the appropriate weight can give the desired result.

Normally, when the windows for artificial ventilation are closed, the air flow through the groove of the fixture does not create an air current, the ventilation duct (4) should be noted, moving from its dormant state to the outside. In case of strong wind outside and strong draft in the window, the air pressure tilts the ventilation duct (4) from its rest position (Fig. 5) to the horizontal position (see Fig. 1), where the ventilation duct (4) completely encloses the groove. closes and therefore prevents excessive pull. The bushing thickening (44) rotates a circle about the axis of rotation such that, as is easily seen in FIG. 4 and 5, the outer plane of the bushing thickening (44) seals the fixture groove with a corresponding sidewall in the rotation of the venting vent (4). Thus, the venting vent may, due to the incoming air, not tilt the beam (41) into a downward position, which again frees the winding passage, on the respective mounting pads, not due to its undesirable position closing the inlet opening of the groove (21). 5) support protrusions which prevent further bending of the venting vent (4), or corresponding support protrusions visible at the bushing thickening (44) which act in conjunction with the opening edge to bind the groove. These protruding protrusions are not, of course, apparent to the skilled person in the drawing.

In the case of particularly strong air movement from the inside to the outside, for example from a heavily salted room, at low outdoor temperatures and still possible draft, the ventilation air moves upright diagonally to the free plane of its bar (41). again obstructs the movement of air through the vent.

It will be understood that, with the longer elbow of the window sash frame, the larger ventilation vents may be arranged one after the other along the plated groove.

In the manufactured example, the ventilation duct is installed in the groove of the lower horizontal elbow of the frame. In other variants, such ventilation ducts can also be installed in the groove of the upper horizontal elbow of the frame.
