The present awning; window construction- '.comprises a substantially rectangular frame-10 preferably fabricated of aluminum, and. including an 'uppertransversermernber 12, r a lowert' transverse member 144 and spacedr parallel sidei members 16 i and 18, the: frame preferably (having 1 a profile incross-section? as shown? particularly in Figures' 4-7.

The upper and lower ends 28 and 30' of the operating bar terminate a L predetermined distance from the upper! and lower: transverse membersll and l i of the frame when theventilators are in :a fully opened po'sition as shownsinFigured.

All ofthe upper ends of the ventilators may be s lidably connected to the operating bars 2'0, but preferablyonly the intermediate ventilators 32"areso connected. This connection is effected by providing an extension 42at each side of the upper end of the" ventilator; which extension carries a suitable headd' pin or roller'44"s1idably "engagedin achannel track '46 mounted "as at 48upon the operating bar 20. The vertical spacing of the tracks 46 and their length are predetermined in accordance with the dimensions of the ventilators and the necessary length of travel of the rollers 44 in the tracks to effect complete opening and closing of the ventilators.

To eliminate the need for a very wide bar at the head or upper end of the frame the uppermost ventilator 34 is preferably slidably mounted on the frame itself instead of on the operating bar. This is accomplished by providing, as in the construction of the ventilators 32, at each side of the upper end of ventilator 34 an extension 48 carrying a pin or roller 50 slidably engaged in a channel track 52 mounted directly upon each of the

side frame members

16 and 18, the tracks 52 terminating at the upper transverse frame member 12 as shown in Figure 3.

The bottom tilt-in ventilator 36 is provided at each side of the lower end thereof with an extension 54 carrying a pin or roller 56 slidably engaged in a channel track 58 mounted upon each

side frame member

16 and 18 adjacent the lower transverse frame member 14 and below the lower end 30 of the operating bar 20.

A means is provided for developing a mechanical advantage in closing the ventilators which effects a large movement of the operating bar as compared to a relatively small movement of the ventilators at the instant of closing. This means comprises a brace bar 60 which is pivoted at one end as at 62 to the side frame member 16. At its other end the brace bar is pivoted as at 64 to each ventilator at a predetermined position intermediate the upper and lower ends of the ventilator. I

A means is provided for slidably connecting the operating bar to each of the brace bars. As shown in Figures 18, this means includes an elongated slot 66 and a headed pin or equivalent projection 68 carried by the operating bar 20 and extending into the slot 66. As shown in Figures -12, the brace bar 70 may have mounted on one face thereof or may have integrallyform'ed in one face thereof a channel track or shoe 72 slidably receiving a headed pin 74 carried by the operating bar 20.

For ease of operation, the slot 66 or track or shoe 72 is preferably generally arcuate. Both the slot 66 and the shoe 72 include

portions

76 and 78 respectively of predetermined length adjacent the ventilator pivots 66. Each of these portions is straight as compared to the remaining arcuate portion of the slot 66 or the shoe 72. Note should be taken of the fact that the brace bars 60 and 70 may be formed of the desired shape with an arcuate lower portion and a straight upper portion and the slot 66 or shoe 72 will follow the contour of the brace bar. In the event that a straight brace bar is used, the slot or shoe provided therein will not be arcuate but will have an upper portion of predetermined length which is upwardly inclined rela-' tive to the longitudinal axis of the lower portion of said slot or shoe in the same manner as the straight

upper portions

76 or 78 are generally upwardly inclined relative to the arc of curvature of the lower portions of the slot 66 or shoe 72.

The upwardly inclined or

straight portion

76 or 78 serves a very important lost motion function as shown in Figure 8. The overall length of the slot 66 and the length of the straight portion 76 relative thereto and the location of the

pivots

62, 64 and the pin 68 are such that when the operating bar 20 moves upwardly the brace bar 6 turns around its frame pivot'62 and moves the ventilators in unison towards a closed position, the upper ends of the ventilators moving upwardly in the channel tracks 46 and 52. When the ventilators are initially closed, the pin 68 begins to enter the straight portion 76 of the slot 66 as shown in solid lines in Figure 8. The final firm locking of the ventilators is accomplished by further upward movement of the operating bar 20 to the point where the pin 68 approaches the end of the straight portion 76 of the slot as shown in dotted lines in Figure 8. Since, as will be described hereinafter, the bottom ventilator 36 is linked directly to the bottom of the operating bar 20, it is manifest that the bottom ventilator can be opened an amount equivalent to the length of the straight portion 76 of the slot before the

upper ventilators

32 and 34 begin to open. The same operation applies to construction of brace bar 70, shoe 72 andstraight portion 78 shown in Figures 10-12. The ventilators can be retained in the locked position by any suitable latch and keeper 80.

It should be further noted at this point that curving the brace bars 60 and 70 or the slot 66 and shoe '72 associated therewith serves as a means to vary the relative motion among the ventilators.

Various means may be used to reciprocate the vertically movable operating bar 20. In the construction employing the bottom tilt-in ventilator 36, the same is a portion of this means. As shown in Figures 2 and 3, the lower end of the tilt-in ventilator is slidably mounted as at 54, 56 and 58 upon the frame. Each side of the ventilator includes a longer link 82 which is terminally pivoted as at 84' and 86 to the bottom of the operating bar 20 and to the ventilator at a point intermediate the upper and lower ends thereof. A shorter link 88 is provided which is terminally pivoted as at 90 and 92 to the frame side member 16 below the operating bar and above the chan nel track 58 and to the ventilator at a predetermined joint just below the pivot point 86.

Another such means is shown in Figure 13. This comprises pivotally instead of slidably connecting each extension 54 of the bottom tilt-in ventilator 36 to the frame side member 16 as at 94. A single link 96 is terminally pivoted to each side of the ventilator intermediate its upper and lower ends and to the bottom of the operating bar 20'as at 98.

And yet another such means is shown in Figure 9. In this construction all of the ventilators, including the bottom one 100, tilt outwardly of the plane of the frame in the same direction. Each side of the upper end of the bottom ventilator 100 carries an extension 102 which is not slidably but directly pivoted as at 104 to the operating bar 20.

Rotatably mounted within the lower transverse member 14 of the frame 10, here shown supporting a conventional screen 106, is a torque bar 108. Secured to each end of the torque bar is a link which is in turn pivoted at its upper end as at 112 to the bottom ventilator at a point intermediate the upper and lower ends thereof. A portion of the torque bar carries gear teeth 114. An operating handle or crank arm 116 is rotatably mounted on the transverse frame member 14 and includes a worm 118 which engages the gear teeth 114 of the torque bar.

As in the case of the tilt-in bottom ventilator 36, operation of the handle 116 in this construction will produce the same mechanical advantage of a large movement of the operating bar and a relatively small movement of the ventilators at the instant of closing. Thus when the ventilators are closed, operation of the handle 116 will raise the lower ventilator 100 a distance equivalent to the length of the straight portion 76 of the slot 66 of the brace bar 60 without effecting any opening of the remaining

upper ventilators

32 and 34. Thereafter, continued operation of the handle 116 will further open the lower ventilator 100 and will cause the remaining upper ventilators to open in unison.

While preferred embodiments of the invention have been shown and described hereabove minor variations thereof may be made by skilled artisans without departing from the spirit of the invention and the scope of the appended claims.
