CHILD-PROOF WINDOW AND BALCONY DOOR Filed MarCh 24, 1966 2 Sheets-Sheet 2 United States Patent O 3,382,611 CHILD-PROOF WINDOW AND BALCQNY DOOR Gustaf Adoli Zandelin, Kungsgatan 58B, Malmo, Sweden Filed Mar. 24, 1966, Ser. No. 537,151 5 Claims. (Cl. 49-67) ABSTRACT 0F THE DISCLOSURE A Window or balcony door has two inwardly horizontally swinging sashes the outer of Awhich is spaced from the top and bottom of the window frame to provide upper and lower ventilation openings. These openings are downwardly outwardly directed to render them weatherproof. The sashes may be selectively individually locked.

The present invention relates to windows and balcony doors of the type that have an outer and an inner frame, the frames being independently rotatable about hinges on a casement frame.

The object of the invention is to produce a window or balcony door in which it is necessary to open only the inner window-frame for the purpose of ventilation, while the outer window-frame remains locked in a closed position to prevent small children falling out of the window.

That which mainly characterizes the window, according to the invention, are the spaces situated above and below the outer window-frame in the easement frame, which are in communication with the open air, and which allow, after the inner window-frame has been opened, stale air to ow out and fresh air to ilow into the room that is to be ventilated.

The window, according to the invention, does not allow heavy rain to penetrate during ventilation, and simultaneously prevents illegal or unwanted entry through the window.

The invention will be described while referring to the appended drawings of an embodiment.

FIG. l shows a front elevation of the window.

FIGS. 2-4 show sections of the window.

FIG. 2 shows a horizontal cross section along the line 2-2 in FIG. 3.

FIG. 3 shows a vertical section along the line 3-3 in FIG. l.

FIG. 4 represents a vertical section similar to that in FIG. 3, but with the inner window-frame open, to show how ventilation can be efeeted thereby.

The numeral 1 indicates a Casement-frame comprising an upper part 2, a lower part 3 and side parts 4 and 5. The easement-frame, as is made clear by FIGS. 2-4, comprises an inner Casement-frame 6, and connected therewith, an outer-easement frame 7 with a somewhat smaller opening. In the space, which is surrounded by the casement- frames 6 and 7, is an outer window-frame 9, sup ported by vertically mounted rotatable hinges 8 on the one side, said window-frame 9 having a glass pane 10 inserted in an inside edge recess and held in position by means of Window molding. An inner window-frame 12 is supported on vertically mounted rotatable hinges 11 on the easement-frame 6, with a glass pane 13 inserted in an inside edge recess, in said window-frame 12, -being held in position -by window molding.

Thus, the window frames 9 and 12 are independent of rice each other and can be rotated about their hinges 8 and 11 respectively.

The inner window-frame 12 is provided with a lockinghandle 14 on the inside, by means of which locking bars or the like 16 can be suitably actuated in conjunction with locking-plates 15 on the easement frame 6.

The outer window-frame 9 is likewise provided with a locking device, which is generally indicated by the numeral 17, and which is preferably made child-proof, i.e. so that it cannot be operated and opened by small children. The child security can be achieved by, for example, a special key being necessary for locking and unlocking, said key being imade inaccessible to children.

There are many types of locking-devices on the market, which can be regarded as child-proof, and are, therefore, suitable for utilization with the window according to the invention.

As is apparent from FIGS. 3 and 4, the upper edge 18 of the outer window-frame 9 does not extend completely up to the inner surface 19 of the easement-frame 6, leaving a space 20, which is connected with the open air by means of a vertical channel 21 between the outer window-frame 9, the upper part of the outer Casement-frame 7, and a board-strip 22 tted on the said upper part which strip serves as a protection against rain.

In a similar way, the lower surface 23 of the outer window-frame 9 does not extend completely down to the inside surface 24 of the easement-frame 6, but instead a space 25 is left, said space being connected with the open air by -rneans of elongated recesses 26 in the casement-frame 7 (two recesses are shown in FIG. l).

When the inner window-frame 12 is unlocked, by means of the handle 14, and the window-frame 12 is swung out about its hinges 11, ventilation is obtained as indicated by the arrows 27 and 28 in FIG. 4, despite the outer window-frame 9 being locked in a closed position. Stale inside air is then able to flow out, in the direction of the arrow 27 into the space 20 through the channel 21 in the upper edge of the outer window-frame 9, said channel being connected with the open air, simultaneously as fresh air Hows in through the recesses 26 in the outer easement-frame 7 and the space 25 in the lower surface of the outer window-frame 9.

Due to the child-proof locking of the outer windowframe 9, it is ensured that no small child runs the risk of falling out, despite the window being adjusted for ventilation.

When it is so desired, the outer window-frame 9 can also be opened, eg. when cleaning, by unlocking and swinging it about its hinges 8.

Different modications of the invention are, of course, possible within the scope of the claims.

I claim:

1. A closure comprising a frame, an inner sash and an outer sash, means independently rotatably mounting said sashes on said frame for inwardly opening horizontal swinging movement about vertical axes between open and closed positions, both said sashes being glazed, there being spaces above and below said outer sash between said outer sash and said frame in the closed position of said outer sash, said spaces communicating with the open air, said inner sash closing said spaces in the closed position of said inner sash, and means for preventing unauthorized opening of said outer sash.

2. A closure as claimed in claim 1, said last-named means comprising latch means accessible only from the inner side of said outer sash.

3. A closure as claimed in claim 2, said latch means being of the type requiring operation by a separate key.

4. A closure as claimed in claim 1, said spaces above and below said outer sash being defined `by downwardly outwardly directed channels thereby to render said spaces weatherproof.

S. A closure as claimed in claim 1, one of said spaces being defined by an opening through said frame.
