Claims. (CI. 20-62) More specifically,

yet so as, at the same time, to permit adequate ventilation. The principal difficulty with the prior louver constructions has related to their cost. Because a plurality of window panes are employed in each window construction and each of these panes had to be supported upon separately formed bearing elements, the window constructions are relatively expensive. Further, the presence of intricate lever constructions in windows of this type has frequently caused many difiiculties for the average householder for, once one of the panes in these windows has become jammed for some reason, it is usually beyond the capacity of the average individual to repair the construction.

It is an object of the present invention to overcome the foregoing and related defects of the prior louver window constructions. A further object of the invention is to produce a new and improved type of louver window construction which is relatively inexpensive, which is relatively foolproof, and which can be easily and c0nveniently manufactured. Further objects of the present invention, as well as the advantages of it, will be apparent from this specification, the appended claims, and the accompanying drawings, in which:

Fig. 1 shows a front view of a louver window in accordance with the invention;

Fig. 2 is an expanded isometric sectional view illustrating the construction of the pivot joint used in the window of Fig. 1;

Fig. 3 is a sectional view of the window of Fig. 1 taken at line 3--3 of Fig. 1;

Fig. 4 is a partial sectional view of the jamb of the invention taken in the direction of the arrow 4 indicated in Fig. 3;

Fig. 5 is a similar partial sectional view taken in the direction of the arrow 5 of Fig. 4; and

Fig. 6 is a sectional view taken at line 66 of Fig. 5.

Briefly, the above and related aims are achieved by forming a louver window construction utilizing a variety of stamped parts of a specific shape holding the window panes employed, and utilizing further an overcenter toggle-lock arm construction to control the movement of all of these panes in unison. Perhaps this type of construction will be best seen with reference to the figures of the drawings.

Fig. 1 shows a new window 10 of the invention comprising a plurality of panels including glass panes 11 having recessed

side portions

12 and 13, as is best shown in Fig. 3. The ends of these panes are disposed within appropriate metal channels 15 having pairs of ear-shaped lugs 16 of the type clearly illustrated in Fig. 2. Each pair of lugs 16 is adapted to fit within complementary openings 18 positioned within a bushing 19 having a depressed boss portion 20 (Fig. 6) and a crank arm comprising an outwardly ofiset shank portion 21 and a pivot portion 22 provided with an aperture 23. These bushings 19 are adapted to fit within bearing openings 26 within jambs 27 of the windows of the invention. These jambs 27 are composed of a central portion 28 and side flanges 29 projecting away from the glass panes 11, concealing the entire bushing and lever or crank construction, as will be more fully explained. The jamb ends 30 are connected together by means of appropriate top and bottom connecting pieces 31. These pieces may be formed in the U-shaped manner in which the jambs 27 are formed, or may consist of other equivalent means.

In use, the lugs 16 are positioned within the openings 18 in the bushings 19 and are bent over on the sides of these bushings remote from the panes 11 in the manner clearly indicated in Figs. 4, 5 and 6 of the drawings. When fixed in position, all of the bushings 19 in each of the jambs 29 are parallel to one another, and those in one of the jambs 29 are connected to each other by means of a rod 35 and pivotal connections 36, the rod being between the portions 22 of the crank arms and the central portion 28 of the corresponding jamb 27, as best shown in Fig. 5. This rod 35 is attached by means of pivot 37 to a link 38 which in turn is connected by means of another pivot 39 to a handle 41 for governing the movement of the various glass panes 11. This handle 41 is attached to the jamb by means of a pivot 42 and is provided with a shank portion 43, as shown in Fig. 5, removed from the two

pivots

39 and 42. and positioned at an angle to them through an aperture 45 in a flange 29. This shank portion 43 is provided with means 44 for connecting the entire structure to an appropriate mechanism for governing the entire movement of the window panes. Such mechanism is not shown inasmuch as it is of a category known to the art.

When all of the panes are assembled together in a closed relationship, as shown in Fig. 1, the handle 41 is normally disposed in the position indicated in full lines in Fig. 5. To open these panes, the handle is moved to the position shown in the phantom view of the same Fig. 5, causing the link 38 to move upward and in turn causing the rod 35 to move in the same direction, rotating all of the bushings 19 in a counterclockwise direction as shown in the same figure. In this open position, the pivot 39 is slightly above the pivot 42 in an over-center type position. In this position, the handle 41 is locked against rotation except when a force is placed upon it so as to return it and the other elements shown to their original closed positions. In this closed position, it will be seen, as shown in Fig. 3, that the

sections

12 and 13 of adjacent glass panes fit together so as to form a weather-proof joint. The upper ends of the channels 15 are provided with slanting joints 17, as shown in Fig. 3 of the drawings, so as to provide a clearly weather-proof construction.

Those skilled in the art will realize that the present invention is capable of many modifications falling within the scope of this disclosure. Insofar as such modifications are covered by the appended claims, they are to be considered part of the present inventive concept. Those familiar with the field will realize that the present invention marks a substantial improvement in that the bushings and all the other parts shown may be readily manufactured from simple aluminum stampings or from readily available bar stock. Separate machining steps, as required in the prior art, are not required with the instant construction. Further, this, construction is relatively simple to manufacture and is, in effect, foolproof.
