1 Claim. (Cl. -62) This invention relates to jalousie-type windows, doors and similar articles, and has for one of its objects the provision of a jalousie construction which will be sturdy, wcathertight and of smooth operation.

It is another object of the invention to provide a window or door construction of the above-mentioned type which can be easily assembled; which can utilize extruded metal for its primary and important parts and particularly its frame elements; which can utilize metal stampings for other operating parts and which parts shall coperate in a manner to provide a well-constructed, easilyoperated device.

More particularly, the invention contemplates the provision of a jalousie-type window or door embodying extruded side members for its frame, which members are arranged to fit in a window or door opening in a manner to assure weather-tightness. The invention also contemplates the provision of a groove in said extruded side frame members in a manner to house the lifter bar for the pivoted pane-holding rocker arms and to facilitate the pivotal attachment of said arms to parts of said side frame members.

With these and other objects to be hereinafter set forth in view, I have devised the arrangement of parts to be described and more particularly pointed out in the claim appended hereto.

In the accompanying drawings, forming a part hereof, and in which an illustrative embodiment of the invention is disclosed,

Fig. l is a front elevation of a portion of a jalousie window or door frame constructed in accordance with the invention;

Fig. 2 is a side view of a portion of the same, looking from the left of Fig. 1;

Fig. 3 is a horizontal sectional view through one of the side frame members;

Fig. 4 is an enlarged sectional view, taken substantially on the line 44 of Fig. 1, looking in the direction of the arrows;

Fig. 5 is a face view of one of the pane-holding pivotal or rocker arms, and

Fig. 6 is a view of the arm looking from the left of Fig. 5.

Referring to the drawing, and more particularly to Fig. 1 thereof, 1 indicates one of the side frame members of the jalousie-type window or door. The frame comprises two of these side members, one only being shown. That at the opposite side of the frame is similar to that disclosed in Fig. 1, and the two side members are connected at the top and at the bottom by the upper and lower rails, one of which is shown at 2. The upper rail 2 includes a forwardly and downwardly bent flange 33 carrying a rubber sealing strip 34 which fits over the top pane.

Mounted in the frame just described are the panes indidicated at 3, the same being preferably, but not necessarily composed of glass. In the closed position, shown in Figs. 1 and 4, these panes 3 slightly overlap, as indicated at 5.

The cross-sectional shape of each of the side frame members 1 is disclosed in Fig. 3, wherein it will be noted that the same is formed with a longitudinal channel 6 which houses the vertically movable lifter bar 7 which is raised or lowered to swing the panes to open or closed position. The lifter bar 7 is raised or lowered by any known means, usually including a crank and gears situated in a housing positioned on the inside of the frame, and which forms no part of the present invention and hence is not shown.

Formed as an integral, forwardly extending part of the frame member 1 is a flange 8, including a vertically arranged rib Q. Pivotally secured to the flange 8, by rivets 14 extending through the rib 9, are the suitable spaced pane-holding rocker arms 11, one of which is shown in detail in Figs. 5 and 6. Each of said arms consists of a metal stamping of aluminum or other suitable relatively thin, non-corrosive material, and it is formed at the front with the flange 12 behind which is positioned the pane 3 of glass or other suitable material. At its lower end the flange 12 is formed with the inwardly-bent lip 13 that takes under the lower edge of the pane 3 and supports the pane. At the top, the rocker arm 11 is formed with the laterally-bent lip 14 which fits over the top of the pane, the pane 3 being thus confined between the forward flange 12, and between the two lips 13 and 14. The arm 11 is also flanged at the rear as indicated at 15 and 16, and disposed between the flange 15 and the back of the pane 3 is a resilient element 17 such as a block of rubber, a spring or other suitable rattle-preventing means. Similarly, a block of rubber 18, a spring or other suitable resilient element is confined between the flange 15 and the back of the pane. Through the arrangement described, each pane is supported at each of its ends by an arm 11, and is held against rattle and vibration.

Each of the arms 11 is positioned on the frame member 1, in a manner to locate its rear end over the channel 6, where said end of the arm is pivotally attached to the lifter bar 7 by the rivet 19 or by other suitable pivotal means. The rocker arms 11 are suitably ribbed, as shown at 21, 22 to lend stiffness and rigidity to a relatively thin, sheet metal stamping. The rib 21, which is located below the pivot 10 acts as a stop, for it contacts with the forward edge of the rib 9 on the frame when the sashes are closed and serves as a seal against rain.

From the foregoing, the operation of the described structure will be readily understood. As the lifter bar 7 is lowered by means of any known suitable mechanism for the purpose, such as by a crank mechanism well known in this art, the spaced arms 11 and the panes 3 supported thereby in the manner heretofore explained, will be swung outwardly on the pivots 10 to open position as indicated in dotted lines and to the extent desired according to the amount of air to be admitted. When the lifter bar is raised, and to the extent shown in full lines in Fig. 4, the arms 11 will be swung inwardly until the panes are brought to the position of slight overlap shown in said figure. The resilient mounting of the panes, attained through the employment of the rubber elements 17 and 18, prevent rattle and vibration of the panes in the arms 11 and the extruded side frame members assure correct alignment of the assembled parts. As will be noted in Fig. 3, the rear end of the channel 6 is defined by a vertical flange which provides a flat, smooth surface against which a screen for the window or door can be fitted and to which it can be secured. Also, the front flange 24 constitutes a facing strip at the front of the frame to closely contact the edge of the window or doormounting opening, and cooperates with the flanges 26 and 27 to insure weather-tightness of fit of the frame.

The various parts of the structure can be made of aluminum; they are easily fitted together and result in an efiective, sturdy and weather-tight structure.

Having described a single embodiment of the invention it is obvious that the same is not to be restricted thereto, but is broad enough to cover all structures coming within the scopelof the annexed claim.
