8 Claims. 01. 20-42 This invention relates to window structures and is more particularly directed to improvements in awning type windows.

In order that an awning window having a plurality of vents be of optimum efficiency, the vents thereof which close simultaneously, must seal tightly against the frame so that the window may be absolutely air and rain tight. It has been found that within the normal tolerances of manufacture, it was virtually impossible to produce an awning window whose vents close simultaneously to obtain weather tight junctures of the vents in those awning windows having fixed pivots connecting the vents to the window frame. In attempting to solve this important problem, some of the present awning windows are provided with adjustable anchors for connecting the pivots to the vent links attached to the vents. In these windows, the normal procedure is to adjust the anchors upon assembly of the window at the manufacturing plant and then to make any necessary readjustments of the anchors after the awning windows have been installed. However, in spite of all these precautions, it has been found that in many instances some of the vents would fail to close tightly and properly for the following reasons:

1. Failure to make a proper adjustment due to lack of skill of the one making the adjustment or to poor engineering design of the window.

2. Climatic conditions causing constant expanding and contracting of the various parts of the operating mechanisms of the windows.

3. Constant use of the window causing wear of the various operating parts of the awning window.

When the vents of an awning window do not arrive at their closed position simultaneously, after the first vent becomes tightly closed, a further turning of the operating handle of the awning window in attempting to eifect a proper closing of those vents still unclosed causes undue strain and wear of the operating mechanism and a consequent buckling of the sliding or actuating bars.

Therefore, it is a principal object of the present invention to provide an awning window with pivot anchoring devices which are self-adjusting so that all of the vents can be brought to their tightly closed positions at all times and without any undue strain on the slide bars and the operating mechanism.

A further object of the present invention is the provision of the above described awning window which is simple in construction and operation, and whose parts are readily replaceable.

A further object of the present invention is the provision of an awning window characterized as above whose anchoring devices are provided with a slidable pivot maintained in position by a resilient member.

A still further object of the present invention is to provide an awning window which when once properly adjusted for simultaneous closing of all vents will need no further adjustment thereof.

With these and other objects in view, the invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings, forming a part of the present specification with the understanding, however, that the invention is not confined to anystrict conformity with the showing of the drawings, but may be changed or modified so long as such changes or modifications mark no. material departure from the salient features of the invention as expressed in the appended claims.

, slide bar 15 by a pivot pin 19 secured thereto.

In the drawings:

Figure 1 is a perspective view of an awning window embodying my invention.

Figure 2 is a sectional view taken along line 22 of Figure 1.

Figure 3 is a sectional view similer to Figure 2 with the vents shown in their closed position.

Figure 4 is an enlarged detailed sectional view of the self adjusting anchoring device as positioned when the vent is in its open position.

Figure 5 is a view similar to Figure 4 of the self-adjusting anchoring device as positioned when the vent is in its closed position.

Figure 6 is an enlarged sectional view taken along 66 of Figure 2.

Figure 7 is an enlarged sectional view taken along 7-7 of Figure 2.

Figure 8 is a view similar to Figure 5 showing a modification of the self-adjusting anchoring device.

Referring now to the drawings wherein similar numerals are used to designate like parts throughout the several views, and in particular to Figures 17 inclusive, the numeral 10 refers generally to an awning window embodying my invention and shown having three vents 11 though any number of vents may be provided in the window as determined by the length or height of window desired. The awning window 10 is provided with a rectangular frame of conventional construction whose

vertical side members

13, 13 have a generally U-shaped cross section thereby forming a vertically disposed slot on either side of the window in each of which a slide bar 15 is slidably mounted. A plurality of rollers 16 are mounted within each of the slots on the wall portion of the members 13; the rollers 16 abutting against the edge portion of the slide members 15 to prevent any sidewise movement thereof.

Each of the vents 11 have a hinge member 18 secured along each side thereof, which member 18 extends beyond the top edge of the vents 11. The free ends of the hinge members 18 are pivotally mounted to the The other end portion of each of the hinge members 18 are provided with a pivot pin 20 upon which is pivotally mounted one end of a vent link 21 whose other end 22 (see Figures 4 and 5) extends through a slot 24 in the rear -wall 13a of the frame member 13. The end portion 22 of the vent link 21 is provided with a bore 25 which receives a pin 26 having a roller 27 mounted on the pin 26 on either side of the end portion 22 of the vent link 21. Since the width of the slot 24 is only slightly larger than the thickness of the end portion 22 of the vent link 21, the rollers 27 will bear against the outside surface of the back wall 13a of the frame 13. A housing 28 which is secured to the outside surface of the back wall 13a by means of

screws

29, 29 threaded therein contains the end portion 22 and a resilient member 30 positioned above the rollers 27 in contact relation with the upper portion of the housing 28 and the back wall member 13a. The function and operation of the resilient member 30, which may be made of neoprene, rubber, a compression coil spring and the like, is explained in detail hereinafter.

At the lower portion of each of the slide bars 15 there is secured a pin 33 on which one end of a link 34 is pivotally mounted. The other end of each of the links 34 is pivotally mounted to one end of a cross shaft arm 35 as at 36 while the other end of each of the cross shaft arms 35 is secured to the end portions of a cross shaft 37 which is housed in the sill or lower horizontal frame member 13b. The pin 33 of one of the slide bars 15 has a power link 38 pivotally mounted thereon; the other end of the power link 38 being pivotally mounted to one end of a power arm 39 whose other end is provided with a segment gear 40 and is pivotally mounted to the frame 13 as at 41. The segment gear 40 is in mesh engagement with a worm gear 42 mounted on a shaft 43 to which an operating handle 44 is secured. An operator housing 44 which contains the aforementioned gearing mechanism is secured by screws 45 to the frame 13.

As is readily noted upon the actuation of the operating 7 3 handle 44 to open the vent 11, the revolving worm gear 42 causes the outward pivotal movement of the power arm 39, the downward sweeping of the link 34 and a downward sliding movement of the slide bar 15. Simultaneously, the power link 34 swings downwardly and outwardly causing the cross shaft 37 to rotate through the medium of the cross shaft arm 35 which is pivotally connected to the link 34. The rotation of the cross shaft 37 effects the swinging of the cross shaft arm 35 at the other side of the window 10 which inturn causes the other link 34 to swing outwardly and downwardly thus compelling the other slide bar to move downwardly in synchronism with the first mentioned slide bar 15. The downward movement of the pair of slide bars 15 causes the pins 19 and free ends of the hinges 18 to move downwardly and thereby compel the vents 11 to swing about the pivot pin 20 to their open position.

By reversing the operation of the operating handle 44, the gear mechanism and the linkages will cause the slide bars to slide upwardly and the vents will return to their closed positions. Due to the tolerances permitted or even possible in the manufacture of awning windows, the pivot pins 19 on the slide bars 15 and the pivot pins 26 on the frame 13 will not be precisely positioned to effect the perfect and uniform closing of each of the vents 11. Now, when a vent 11 closes before the other vents are in a closed position, a further actuation of the operator handle 44' will cause acontinued upward movementof the slide bars 15 and the vent or vents that have first arrived at their closed position will cause a slight upward movement of the vent link 21 and of the rollers 27 thereby exerting a compressive pressure against the resilient member 30. When all of the vents 11 are in their closed position, the resilient members 30 will be distorted in direct proportion in the order in which the particular vent to which they are attached become closed; the last vent that closed causing its resilient member 30 to be dis torted the least amount. It can be seen that within certain limits, the failure of all the vents 11 to close simultaneously will not prevent the proper closing of all the vents 11; this closing of the vents 11 will not cause any undue strain of the operating mechanism or a buckling of the slide bars 15.

Referring now to Figure 8 wherein a modification of my invention is shown, the lower portion of the free end 22 of the vent link 21 is provided with a lug 47'. A second lug 48 is secured to the outside surface of the frame 13a. A coil spring 49, which has its end portions engaging bores in the

lugs

47 and 48, yieldingly urges the free end 22 and the rollers 27 to their lowermost position as does the resilient member 30 shown in Figures 4 and 5 and previously discussed. As the vents 11 are brought to their closed position, the upward movement of the vent link 21 will cause the upward sliding movement of the free end 22 against the yielding force of the coil spring 49. When the vents are brought to their open position, the coil springs 49 will return the free end 22' of the vent link 21 to its lowermost or normal position in the housing 28.
