United States Patent 3,220,465 WINDOWS Henry Leiser, 3-D Windows, Inc., Mile High Center, Room 1402, Denver, Colo. Filed May 17, 1963, Ser. No. 281,157 8 Claims. (Cl. 160-92) The present invention relates to windows, and more particularly to windows having sashes which are hinged at their lower ends for swinging movement between opened and closed positions, and which sashes have screened frames pivotally connected to their upper ends.

For many years, double-hung windows and casement type windows, pivotal about vertical axes, have been widely used in the construction of residential and commercial buildings. In recent years, however, such windows have not satisfied all of the requirements of designers, builders and users, and other types of windows have been suggested to obtain greater entry of light, better weather proofing, more attractive appearance, or for other reasons.

vAmong the windows which have found wide spread use are the louver windows, which are characterized by a multiplicity of glass panes, each of which is approximately 4 inches or 6 inches high, the panes being swingably mounted about horizontal axes for opening and closing movements. These louver windows require a large number of parts, and thus are somewhat expensive. They. are diflicult to seal, so that louver windows are seldom used in colder climates, except in such places as porches and breezeways. In addition, this type of window, to be screened, requires the entire opening to be screened or else requires attachments or the like extending from each of the glass louver elements, either arrangement being somewhat more expensive than desirable.

In another form of window, relatively large panes were mounted in vertical array, each of the panes being in clined. Generally, such windows were characterized by inadequate ventilation openings and inadequate screening. They were complex in construction, particularly if the window sashes were movable in addition to being inclined. Such windows generally were not secure against unauthorized removal, particularly when opened, so that entry into a building through such a window was not prevented. Such windows also were generally diflicult to clean, particularly the outside of the window panes, and were difficult to reglaze.

An object of the present invention is to provide a window which will have an ornamental and pleasing appearance.

Another object of the present invention is the provision of a window which may be readily and adequately opened to provide ventilation into the building.

Yet another object of the present invention is to provide a window having a self-contained shading element.

A further object of the present invention is the provision of a window providing a minimum obstruction to the entry of light.

A still further object of the present invention is to provide a window which will be secure in either opened or closed position against unauthorized removal and which will not permit unauthorized entry into the building in which the window is located.

Another object of the present invention is the provision of a window which may be readily removed from the interior of the building to permit cleaning of the exterior of the pane, or reglazing.

Yet another object of the present invention is to provide a window which will be economical in construction 3,22,465 Patented Nov. 30, 1965 "ice and readily fabricated of parts and materials which are readily available.

Still another object of the present invention is the provision of a multiple-section wind-ow permitting indirect ventilation of a room through each section thereof.

A further object of the present invention is to provide a window which will prevent accidental falling therefrom or therethrough, as by children.

Still another object of the present invention is the provision of a window meeting the above desideratum and including a screen which is moved into position when the window is opened.

Other objects and the nature and advantages of the instant invention will be apparent from the following description taken in conjunction with the accompanying drawings, wherein:

FIG. 1 is a vertical cross-sectional view, with parts broken away, of a window in accordance with the present invention.

FIG. 2 is an enlarged view of the area designated by the arrow 2 on FIG. 1.

FIG. 3 is a view similar to FIG. 2, but with the parts in a different position.

FIG. 4 is an enlarged view, with parts broken away, of a locking arrangement for the window of FIG. 1.

FIG. 5 is a perspective view of a portion of the window of FIG. 1, showing a security lock.

FIG. 6 is a cross-sectional view taken on the line 6-6 of FIG. 5.

FIG. 7 is a cross-sectional view taken on the line 77 of FIG. 1.

Referring now to the drawings, wherein like or corresponding parts are designated by like or corresponding reference characters throughout the several views, there is shown in FIG. 1 a window generally designated 10 comprising a header 11, a sill 12 and a pair of jambs, jamb 13 being shown. The several parts of the window, including the sashes, are preferably made of extruded aluminum. Header 11 and sill 12 have crescent shaped channels 16 integrally formed thereon, as during the extrusion process by which they were made, to provide receiving elements for screws. By this construction, the jamb 13 may be secured to header 11, for example, by screws inserted through the jamb 13 and screwed into the crescent shaped channels 16, one such screw being shown at 17.

Header 11 has near its outside edge a groove 18 into which extends a flange 19 of a drip cap 20. As may be seen, drip cap 20 extends outwardly and downwardly from the outer edge of header 11 and has a lower horizontal flange 21. The end of the drip cap 20 is closed by a suitable plate 22.

A fixed shelf 25 extends inwardly from the drip cap 20, and lies in a plane parallel to and below the header 11. At its outer edge, as shown in FIG. 2, fixed shelf 25 has an upstanding flange 26 with an upper curved end 27. Extending inwardly from flange 26 is an abutment 28, and below the free extremity of curved end 27 is a recessed portion generally designated 23.

Referring again to FIG. 1, it will be seen that shelf 25 has at an intermediate part thereof an outwardly facing hook element 29, and at its inner edge has another outwardly facing hook element 31 (see also FIG. 4) and a groove 32, in which is lodged a longitudinally extending weather strip 33.

A second, intermediate fixed shelf 25 is positioned generally below and parallel to the upper fixed shelf 25, and has the same shape. A side plate 35, of generally triangular configuration, is secured to the jamb 13, and has at its outer, inclined edge a laterally inturned flange 36 (see FIG. 7) with a recess 37 therein which receives weather stripping 38. As will be understood, there is a similar side plate and side rail opposite the side plate 35 and side rail 36. The side rail 36 is inclined, and extends from the inner edge of the upper shelf 25 downwardly to the outer edge of the intermediate shelf 25.

A glazed sash 49 is provided, formed of extruded aluminum sections and including a bottom rail 41 which may be seen in FIGS. 2 and 3 to include an outer flange 42 and an oppositely disposed inner flange 43 defining between them a groove having a pair of arcuate connecting portions 44 and 45 separated by an opening 46 in which is weather stripping 47 having an outer face which connects the arcuate portions 44 and 45. At the lower end of the inner flange 43 is an outwardly facing flange 48. The curved end 27 of fixed shelf 25 forms a bearing surface for the bottom rail 41 of sash 40, so that sash 40 may pivot, as between the positions shown in FIGS. 2 and 3. As will be understood, the arcuate portions 44 and 45 will bear upon and be journaled on the curved end 27, and the arcuate face of weather strip 47 will always be in contact with the outer surface of curved end 27. As shown in FIG. 3, movement of the window in an opening direction is limited by the engagement of flange 48 with abutment 28. In addition, translational movement of sash 40 away from the curved end 27 (upwardly and to the right asshown in FIG. 2) would be stopped after a limited amount of movement by engagement of flange 48 with the free extremity of curved end 27 of flange 26. However, when sash 40 has been moved to the position shown in FIG. 3, in an opening direction, with recess 23 permitting movement of sash 40 without engagement of flanges 43 and 48 with the lower part of fixed shelf 25, the entire sash 40 may be removed from engagement with fixed shelf 25 by sliding it in its plane generally upwardly and to the right as seen in FIG. 3. Separation is permitted because flange 48 will not strike the free extremity of curved end 27 since it will clear the free extremity of curved end 27 as the entire sash 40 is moved on a bearing engagement between the underside of flange 42 and the outer surface of curved end 27.

At its upper edge, sash 40 has an upstanding flange 51 (see FIG. 4) with a generally cylindrical terminal portion 52, and a lug 53 immediately below terminal portion 52. Below flange 51 is a second upstanding flange 54 having a latch device 55 secured to it, at approximately its lateral mid point. Latch device 55 includes a housing 56, parts of which are shown broken away, with a handle lever 57 pivoted at 58 therein. Handle lever 57 terminates within the housing 56 in gear teeth 59 which are in mesh with gear teeth 61 on a latch element 62. Latch element 62 is pivoted in the housing 56 at 63 and has a hooked end 64 which may be engaged with the hook element 31 of fixed shelf 25.

A frame 65 having the screen 66 (see FIGS. 4 and therein is provided with an inner rail 67 having a longitudinally extending cylindrical recess 68 which receives the cylindrical portion 52 of sash 40, to thereby permit relative pivotal movement between sash 40 and frame 65. Such pivotal movement is limited by the lug 53. The frame 65 may be separated from sash 40 merely by sliding movement along the axis of cylindrical portion 52. Along its outer edge, frame 65 is provided with an inwardly turned hook element 69 which may engage either hook element 29 of fixed shelf 25 or with hook element 31 thereof as is shown in the upper portion of FIG. 1 to hold the sash 40 in partly opened or fully opened position.

A security lock '70 is provided and comprises a spring strip 71 (see FIGS. 5 and 6) secured at one end by a rivet 72 to the jamb 13 and having at its other end a slot 73 which receives a head 74 of a pin 75. Pin 75 extends through a hole 76 in jamb 13 and has a large, flattened head 77 on the side of jamb 13 opposite spring strip 71. Consequently, and as Will be understood, the pin 75 may be pushed to the dotted line position, against the force of spring strip 71, to thereby permit the sash to be rotated in an opening direction (clockwise, as shown). As will be seen from the upper section of FIG. 1 and from FIG. 6, the sash 4G is in its fully opened position, with hook element 69 of frame 65 in engagement with hook element 31 of fixed shelf 25. In this position, sash 40 does not contact security lock 70, but is slightly spaced therefrom. Also, in this position, the bottom portion of sash 49 is in substantially the position shown in FIG. 2, relative to curved end 27.

The sash 40 in the lower section of window 10 is shown in the closed position, and it will be seen that the hooked end 64 of latch device is in engagement with the hook element 31 (see also FIG. 4) of intermediate fixed shelf 25. The frame 40 is pressing against weather stripping 38 in the side rails 36, as is seen in FIG. 7, the weather strip 47 in the frame 40 is against the curved end 27 of the lower shelf 25 and at its upper end the frame 40 presses against the weather strip 33 in intermediate shelf 25. There is thereby provided a completely secure and weather proof closure. The frame with its screen 66 is stored above the intermediate shelf 25, its outer end resting on intermediate shelf 25 as permitted by the free pivotal movement between frame 65 and sash 40. The sash 40 is thereby inclined, having a pleasing and distinctive appearance and is secure against unauthorized entry in this position. The frame 65 is stored in an out of the way position, and one which permits the sash 40 above it to be opened, as shown in FIG. 1.

When it is desired to open the sash 40, the handle 57 of the latch device 55 is manipulated to raise the end 62, thereby permitting the sash 40 to swing inwardly, pivoting on curved end 27 of shelf 25. To provide for an intermediate opened position, the hook element 69 of frame 25 may be engaged with hook element 29 of fixed shelf 25, or the sash 40 may be moved to the fully open position, which is shown in the upper portion of FIG. 1. In this position, the hook element 69 of frame 65 engages with the hook element 31 of fixed shelf 25. While the sash 40 and frame 65 may be manipulated from the outside, with eventual disengagement of hook elements 31 and 69, and further clockwise rotation of sash 40, sash 40 may be rotated in an opening direction only until it engages with the two security locks 70. Further opening movement of sash 40 can then be accomplished only by depressing security locks as above described, and this can be accomplished only from within the building; frame 65 may be rotated a limited amount as rotation is restricted by lug 53. Thus, an intruder could only effect movement of the sash 40 inwardly until engagement with security lock 70. Further, the sash 46 may not be removed from engagement with fixed shelf 25 because security lock 70 will prevent it from moving to the position shown in FIG. 3 in which it can be withdrawn from such engagement by translational movement.

There has been provided a window construction having an attractive and distinctive appearance. This construction may be readily fabricated, and as will be understood all materials used therein are readily accessible. While children and others having a tendency to lean against a window could fall out of ordinary windows, such action would only tend to close the window of the present invention. The sash may be removed from the window after manipulation of the security lock from within the building, to thereby permit cleaning and reglazing of the sash. The ventilation obtained is indirect, adequate, variable and independent from sash to sash. The window herein provided is fully weather stripped.

It will be obvious to those skilled in the art that various changes may be made without departing from the spirit of the invention and therefore the invention is not limited to what is shown in the drawings and described in the specification but only as indicated in the appended claims.
