4 Claims. (Cl. -42) This invention relates to an awning window mechanism by means of which a window sash in closed position, may be moved and guided downwardly at its upper end and outwardly and upwardly at its lower end from a vertical closed to a horizontal completely open position, the window being provided with means for holding it at any angular position between closed position and its extreme open horizontal position.

The window sash, in the intermediate positions between the two extremes, extends downwardly and outwardly at an angle to the vertical serving when in such I positions a function similar to an awning in stopping and directing water, during rain, away from the window opening in substantially the same manner as an awning. Such windows are therefore known in the art as awning windows.

Windows of the type noted are, in general, of relatively heavy weight; and the mechanism which governs their opening and the holding of the windows in the indefinite number of positions they may take while open, is subjected to considerable stress. Also the mechanism for opening and governing the opening and closing of the awning type windows has heretofore in general been of a more or less complicated and expensive type. With our invention, simplicity of structure is attained with attendant economy in manufacture, while the strains to which the mechanism is normally subjected are substantially eliminated. A marked advance in simplicity of structure, ease of operation and sturdiness and durability in service has been attained as will appear, together with other objects and purposes of the invention, as an understanding thereof is obtained from the following description taken in connection with the accompanying drawings, in which,

Fig. 1 is a vertical section, substantially on the plane of line 1-1 of Fig. 6, looking in the direction indicated,

and showing the window closed.

Fig. 2 is a like section, the window sash being in its completely open, horizontal position.

Fig. 3 is a fragmentary enlarged vertical section, substantially on the plane of line 33 of Fig. 2, looking in the direction indicated.

Fig. 4 is a fragmentary enlarged horizontal section substantially on the plane of line 4-4 of Fig. 2, looking downwardly.

Fig. 5 is a fragmentary sectional view upon the same section line as Fig. 3, the position of the parts as shown therein being with the window closed, as in Fig. 1.

Fig. 6 is a front elevation of an awning type window to which our invention is applied, and

Fig. 7 is a perspective view of a part of the window sash guiding and holding mechanism which is attached at the upper end of the movable window sash.

Like reference characters refer to like parts in the different figures of the drawings.

The window frame has spaced vertical sides 1 and upper and lower horizontal cross frame members 2 and 3 which, between their inner and outer edges, are formed to provide back stop shoulders 4 against which the adjacent side portions of the sash frame are adapted to engage when the'sash is in its vertical closed position.

At each vertical side 1 of the window frame, at the inner side thereof and outwardly from the back stop 4 a vertical guide member of flat or sheet metal is secured. It is shaped into channel form, having a web 5 and an inner flange 6 at right angles thereto, with an outer double thickness flange 7, the metal being formed and bent back upon itself as shown in Fig. 4, which is continued in a flat section 8 located in the same plane with the web 5. The inner flange 6 comes against the back stop 4 of its associated vertical side 1 of the frame, While the web 5 and the section 8 come against the inner sides of the vertical frame member 1 outwardly of the back stop 4. Screws passing through the section 8 and driven into the vertical frame member 1 secure such guide channel permanently to the window frame.

The movable window sash which is to fill the frame opening has spaced vertical sides 9 and upper and lower horizontal cross frame members 10 and 11 forming a frame in which a glass plate or plates are mounted. Two of such plates 12 are shown in the drawings, but it is apparent that the number of such glass plates or panes may be varied without affecting the invention. As shown in Fig. 3 the side of the sash frame is recessed or cut away for a part of its width and a plate 13 of metal is permanently secured to said side. It is to be understood that such plate 13 is used at both sides of the window sash, to serve as a support for a roller carriage connected with each plate which in turn guides and holds the sash in positions to which it may be moved.

A plate 14 of generally triangular shape, at its inner upper corner is pivotally connected at 15 to the upper end of each plate 13 (Fig. 7) and at one side thereof has spaced apart nylon rollers 16, which traverse the described channel between the flanges 6 and 7. An elongated flat bar 17 has an oflset section 17a at its upper end pivotally connected at 18 at the lower corner of one of the plates 14. Such bar 17 lies against the web 5 of its associated channel between the flanges 6 and 7. In the length thereof are a succession of spaced openings 19, except at its free lower end a vertical slot 19:: open at its lower end is cut, though such slot is not essential and may have an opening 19 in its stead. The upper closed end of the slot 19a (Fig. 5) is shaped with an inclined cam surface as shown at 20. A flat supporting or brace bar 21 is pivotally connected at its upper end to the lower end of each plate 13 and at its lower end to a rectangular plate 23 which extends between the flanges 6 and 7 adjacent their lower ends, its outer side being flush with the free edges of said flanges. The plate 23 is permanently secured by welding or other equivalent connection to such flanges.

At an intermediate point between the upper and lower ends of the channel guide, the side 1 of the window frame at which the bar 17 is located is cut away and recessed to provide a rectangular or substantially square recess 24. A flat plate 25 is permanently secured by screws in the bottom of such recess (Fig. 4). A lever 26 is pivotally mounted between its ends at 27 on such plate using overlapping ears on the plate and lever (Fig. 2). One end portion of the lever extends across the channel flanges 6 and 7 which are notched or recessed at their free edges a depth equal substantially to the thickness of the lever.

A pin 28 at the inner side of such end portion of the lever is permanently secured thereto, being adapted to enter any of the recesses 19 or the slot 19a when in conjunction therewith.

The opposite end of the lever is acted upon by a light strength coiled compression spring 29 between it and the base plate 25. After such latching lever has been installed in place, a back stop bar 30 is placed thereover and secured at the inner sides of the frame member 1, and also the lower and upper sides of the top 2 and sill 3 of such frame. A cylindrical opening is made through the back stop 30 over the inner end of the lever 26, through which a metallic guide sleeve 31 is inserted integral with attaching ears 32 at its outer end which are screw connected to the stop 30 as in Fig. 1.

An actuating rod 33 having a head at its inner end passes slidably through the sleeve 31, its inner end head bearing against the adjacent end of the lever 26. At its outer end it is equipped with a push button 34 for manual operation by the thumb or finger of an operator who, in this manner, may turn the lever 26 about its pivot to withdraw the part 28 from any recess 19 in which it is received. Y

With the window closed, as in Fig. 1, it may be pushed outwardly at its lower end, and at the extreme of movement, will reach horizontal position as shown in Fig. 11, passing through all of the indefinite number of positions between the closed and such fully open position. The latch release by pushing on the button 34 frees the bar 17 for movement downwardly between the guide flanges 6 and 7, the upper end of the window sash moving vertically downward and being held against other than vertical movement by the plates 14 and the rollers 16 thereon which are between the flanges 6 and 7 of the channel guides. In such movement of the bar 17, the succession of openings 19 will pass, one after another, by latching pin 28, and at any position where the latching pin 28 is in conjunction with an opening 19 the latch may be released to engage the bar 17 and thus releasably lock the window sash in an inclined position. The number of such differently inclined positions in which such window sash may be held is controlled by the number of the openings 19.

To return the window to closed position, for example, from its horizontal position in Fig. 2, the inner end of the window is pushed upwardly and the sash moves simultaneously upward and inward until it reaches closed position as in Fig. l.

The structure described is simple, economical, easily installed and very sturdy and durable in use. The forces which are transmitted through the bar 17, the locking pin 28 and thence to the lever 26 are sustained substantially wholly, if not entirely, by the shoulders at the ends of 1 the recesses in flanges 5 and 6 between which the outer end of the latch lever 26 is located when in its operative holding or locking position.

The invention is defined in the appended claims and is to be considered comprehensive of all forms of structure coming within their scope.
