Hagersten, Sweden, assignors to Percy Tham Aktiebolag, Oxelosund, Sweden, a company of Sweden Filed Apr. 7, 1960, Ser. No. 20,728 Claims priority, application Sweden Apr. 7, 1959 4 Claims. (Cl. 20-42) This invention relates to windows and its object is a window that is hinged at the top on horizontal hinges to allow of its being opened for ventilation, and also can swing on vertical hinges at one side, preferably inward, to give access for cleaning.

For this purpose there is attached to the fixed window frame by vertical hinges at one side an auxiliary, swinging, frame in which the window sash is supported by pivot pins near its top turning and Sliding in slotted fittings attached to the swinging frame, and by a link pivoted to the swinging frame near the bottom of it and to the sash at a higher level. There may be fastening screws to secure the free edge of the swinging frame to the fixed frame. The free edge of the sash may be locked to the swinging frame by horizontal rods which can be thrust into fittings on the swinging frame.

An embodiment of the device according to the invention is illustrated by way of example in the accompanying drawings.

FIG. 1 shows a doubly glazed window shut, viewed from the inside;

FIG. 2 is a section on line II-II in FIG. 1;

FIG. 3 shows the window in position for rapid ventilation, the window frame being shown in vertical section;

FIG. 4 shows the window in position for cleaning, the window frame being shown in vertical section;

FIG. 5 is a plan view of the Window in position for cleaning.

The reference numeral 2' designates the window frame to which an auxiliary sash or frame 4 (the swinging frame) is hinged by hinges 3 on one vertical side. A fitting 5 having a substantially vertical slot 6 is fixed on each side of the swinging frame near its top. Pins 8 are attached to the inner sash 7 of two coupled sashes 7, 19, near its top and slide in the slots 6. One end of a link 9 is pivoted to the swinging frame 4 near the bottom of it and the other end of said link is pivoted at an intermediate point to the inner sash 7. The outer sash 10 is pivoted in the usual manner to one vertical side of the inner sash 7 and secured at the other side by coupling fittings not shown in the drawing.

To each vertical side of the swinging frame 4 near its lower end there is fixed a fitting 11 having a hole 11:: to receive one end of a locking rod 12 provided in the inner sash 7, both when the window is shut and when the sashes are in the position for cleaning, the locking rods being moved in and out by a handle 1211. As mentioned above, one side of the swinging frame 4 is sidehinged to the window frame 2. The other vertical side of the swinging frame may be locked to the window frame 2 by means of coupling screws 13 or the like when the window is shut.

A window constructed in accordance with the invention is operated in the following manner:

When the window is to be opened for ventilation the ice handle 12a is turned counter-clockwise to a vertical position. The ends of the locking rods are thus disengaged from the holes 11a in the fittings 11, and the lower portions of the coupled sashes 7 and 10 can be swung outwards, the pins 8 sliding downwards in the slots 6 to their lower ends and the links 9 turning outwards (countar-clockwise in FIG. 3) to hold the sashes in the ventilating position.

When the windows are to be cleaned, the vertical side of the sashes opposite the hinges 3 is loosened from the window frame, for instance by unscrewing the coupling screws 13, so that the sashes 7 and 10 together with the swinging frame 4 can be swung into the room on the hinges 3. The inner coupled sash 7 is in this position still secured to the swinging frame 4 by the locking rod 12. Coupling fittings provided in addition to the coupling screws 13, in the coupled sashes 7 and 10 are released so that the outer sash 10 can be swung away from the inner sash,(see FIG. 4). In this position the inner sash 7 and the swinging frame 4 form a rigid unit.

The invention is not restricted to the embodiment shown and described but the details may be varied within the scope of the invention.

What we claim is:

1. In a window: a stationary frame having vertical sides; an auxiliary swinging frame hinged by vertical hinges onto the inner face of one vertical side of said stationary frame and adapted to swing inwardly of the latter; a glazed sash suspended in said auxiliary frame, said sash swinging inwardly with said auxiliary frame, thereby allowing the cleaning of the outer surface of said glazed sash; said auxiliary frame and said sash having vertical sides; a fitting facing said sash at the upper portion of each vertical side of said auxiliary frame; a substantially vertical slot in each of said fittings; pins extending horizontally from the upper portion of each vertical side of said sash and engaging said slots and movable vertically therein; said sash being suspended movably in said auxiliary'frame by means of said slots and pins, for swinging outwardly of said auxiliary frame to an open position for ventilation, when said auxiliary frame is closed against said stationary frame; links articularly connected at one end to the lower portion of the vertical sides of said auxiliary frame and at their other end to the middle portion of the vertical sides of saidsash, and adapted to extend outwardly of said auxiliary frame to maintain said sash in its outwardly open position for ventilation.

2. In a window as claimed in claim 1, coupling means for fastening to said stationary frame the vertical side of said auxiliary frame opposite to the vertically hinged side of said auxiliary frame.

3. In a window as claimed in claim 1, a bored fitting fastened to the lower portion of each vertical side of said auxiliary frame; movable means connected with the lower side of said sash, said movable means being ongaged in said bored fittings to lock together said sash and said auxiliary swinging frame in their closed position and in their inwardly open cleaning position, said movable means being disengaged from said bored fittings to allow the outward opening of said sash away from said auxiliary frame for ventilation.

4. In a Window as claimed in claim 1, an outer glazed sash fitting onto the outer surface of said glazed sash,

7 3 V i said outer sash having vertical sides; vertical'hinge's between said outer sash and said sash on one vertical side of said outer sash and said sash, these sidesbeing adjacenteach other, said outer sash being swingable on said hinges outwardly from said sash when said auxfliary' g ether and against said auxiliary frame, thereby allowing the closing of said auxiliary frame against said stationary frame.
