Kuhn, W. 198 55. 11%3 Racine Ave, Rte. 3, Muslregou, Wis. Filed July 24, 1963, Ser. No. 297,288 1 Claim. (Ci. 49-397) The present invention relates to top hung pivoted window sash of the type customarily embodying a plurality of light transmitting panes. Such sash is customarily used in industrial establishments and is employed for both ventilating and light transmitting purposes. Hence it is pivoted along the top edge thereof so as to swing outwardly when opened, for passage of (both light and air. When the sash is closed it provides a Weather seal with the adjacent building structure.

The present pivoted sash may be initially installed upon a new building or may be employed to replace existing conventional fixed or movable sash. Accordingly, the sash of the invention provides its own weather seal with the building, whether such seals be with the original window sill members or additional sill members in stalled during a renovation. Therefore, the invention also embodies suitable end sealing means as well as 1ongitudinal sealing means.

Aluminum has been currently used as sash material due to its lightness and corrosion resistance. Due to the wide variety of window size openings encountered in industrial buildings, the sash is usually custom made even though certain stock sizes may also be available or embodied therein. The present invention thus embodies construction which facilities custom construction from long stock lengths of the sash members; such sash members may be of aluminum, rigid vinyl or other suitable materials.

Industry now customarily employs corrugated plastic sheets as windows due to its resistance to breakage. The invention, therefore, contemplates a readily adjustable sash for receiving a plurality of different widths of such plastic sheets during initial construction.

One object of the present invention is to provide a top hung pivoting sash construction which readily lends itself to custom construction to meet the users needs.

Another object of the invention is to provide a sash of the character described which readily seals itself against weather and dirt.

A further object of the invention is to provide a simple economic design of sash which is strong and is assembled with a minimum of labor.

These and other objects of the invention will be made apparent from the following description and the drawing forming a part thereof, wherein:

FIG. 1 shows in front elevation a portion of a building with a sash of standard length comprised of three panels;

FIG. 2 shows an enlarged typical vertical section taken on lines II-II of FIG. 1;

FIG. 3 shows an enlarged typical longitudinal section taken on lines III-III of FIG. 1;

FIG. 3A shows an enlarged typical longitudinal section taken on FIG. 1 illustrating the manner of splicing two standard frames.

FIG. 4 shows an enlarged typical vertical section taken on lines IVIV of FIG. 1, illustrating a typical crosssection through the panel splice bars; and

FIG. 5 shows an enlarged typical vertical end view of the sash taken on lines V-V of FIGS. 1 and 3.

Referring now in detail to the drawings, particularly FIGS. 1 and 2, the sash of the invention may be disposed vertically in substantially parallel relation to the building vertical wall within which the sash is mounted, or the Patented August 16, 1966 sash may be sloped outwardly as when the sash is mounted in a monitor or saw toothed roof structure. For purposes of illustration the sash of FIG. 1 will be considered as being mounted in an elongated window opening in a vertical (wall of the building. The metal upper sill 1 of the window opening is disposed in substantially the vertical plane of the building wall 2 and the bottom sill 3 of the window opening is recessed inwardly of the vertical plane of the Wall 2. At each vertical side Wall of the window opening is a vertically disposed substantially Z shaped flashing member having one inturned leg 4 secured to the building wall, a web member 5 disposed in a direction transversely of the window opening and an outtunned leg 6.

Secured to the inner face of the upper sill 1 and extending transversely of the window opening is the sash hanger member indicated generally as 7 and which may be longer than the sash top member. Member 7 is preferably an aluminum extrusion comprised of a plate-like body portion 8 having suitably spaced openings 9 therein receiving suitable fasteners 10 attaching it to the sill 1. At the upper end of the body portion 8 is a thickened portion 11 having a substantially circular passageway 12 therethrough with a slotted opening 13 in the periphery thereof. Mounted in said pasageway 12 and extending through said opening 13 is dirt guard 14 overlapping member 17. At the bottom of body portion 8 is an arcuate outwardly projecting portion 15 having an enlarged inturned portion 16 disposed in spaced relation to body portion 8 and arcuate portion 15 providing a pivotal support for the movable sash frame top member '17 as hereinafter discussed. The herein described member 7 is illustrated in FIGS. 2 and 5. An alternate form of member 7 is shown in FIG. 4, wherein member 7A at the upper end of plate portion 8a is flat and has on the inner surface thereof a recess A receiving the flange 14b to retain the member 14a in position. Member 14a and member 14 are of any suitable material such as vinyl plastic or metal and extend substantially the length of members 7 and 7a.

The movable sash frame is comprised of top and bottom members indicated generally as 17 and 18, connected by intermediate members and end members indicated generally as 19 and 20 respectively. Top member 17 preferably of extruded aluminum having a. rear wall 21 terminating at the lower end thereof in a flange Z2 and terminating at its upper end in a forwardly extending arcuate portion 23. Intermediate its ends wall 21 has a fonwardly extending portion 24 terminating in a depending wall 25 having an inturned bottom flange 26 spaced from flange 22 of Wall 21. The portion 24 with walls 21, 25 and their opposing flanges provide an enlarged recess to receive the ends of the plastic panels and their closure member. Walls 21 and 25 have on their inner faces opposing projections 27 and 27a.

The sash bottom member 18 is preferably an aluminum extrusion of substantially angle shape having a front wall 28 and rearwardly extending top wall 29. Extending longitudinally of the under surface of wall 29 are passageways 30 for engagement by screw-threaded fastening members as hereinafter discussed. Upon the front face of wall 28 is a longitudinally extending closure member supporting ledge 31 and a similarly extending recess 32 for engagement by screw-threaded panel fastening members, as hereinafter discussed. Upon the inner face of wall 28 adjacent the lower end thereof, is a suitably shaped longitudinally extending recess 33 for reception of a sealing member, such as 34, providing a weather seal with the adjacent face of building window lower sill 3.

Extending between the upper sash member 17 and lower sash member 18in overlapping relation therewith are a plurality of spaced suitably corrugated plastic panel members 35. The adjacent spaced vertical edges of such panels 35 are secured in place by struts or mullions indicated generally at 19, extending between the sash members 17 and 18. Each strut 19 is comprised of an inner member 36 and an outer member 37. Inner member 36 is preferably an aluminum extrusion comprised of a longitudinally extending transversely disposed Web portion 38 having on its rear face a centrally disposed rearwardly extending portion 39. Extending forwardly of web 38 and preferably equally spaced about the longitudinal center line thereof are two longitudinally extending portions 40 spaced at 49a to be engaged by a screw-threaded member entered between them. Extending laterally outward from each portion 40 is an arcuate portion 41 conforming substantially to the contour of the adjacent edge portions of a plastic panel to be engaged therewith. Each -arcuate portion 41 is preferably provided with longitudinally extending serrations 42 to grip the plastic panel engaged therewith. As shown in FIG. 4 of the drawing, member 36 has the portions 40 removed adjacent the upper end thereof so that the web 38 may overlappingly engage the inner face 21 of top sash member 17 and secured thereto by suitable means such as screws 59. Member 36 has the web 38 removed from a portion of the lower end thereof so that portions 40 may overlap and abut the front face 28 of the bottom sash member 18 with portion 38 substantially abutting portion 29 and secured thereto by screw fastener 60. The outer strut member 37, as best shown in FIGS. 3 and 4, is comprised of a flat longitudinally extending central portion 43 having laterally extending arcuate portions 44 at opposite sides thereof. The inner faces of ar-cuate portions 44 have longitudinally extending serrations for gripping the plastic panel engaged thereby. Suitable apertures 45 spaced longitudinally of member 37 receive screw-threaded members 46 which engage the inner faces of portions 40 and member 36, cutting threads therein, to clamp the two members 36, 37 together with the edge portions of the plastic members disposed between them. As best shown in FIG. 4, inner strut member 36 at its upper end overlaps wall 21 of sash member 17 and is attached thereto by suitable fasteners 59, and the base of strut member 36 is disposed adjacent Wall 29 of bottom sash member 18. A suitable fastening member 60 connects said wall 29 with portion 39 of the strut 36.

Defining the vertical end edges of the sash, as best shown in FIGS. 3 and 5, are oppositely disposed angle members 20 and 20a extending between and connected to the ends of the upper and lower sash members 17, 18. As best shown in FIG. 3, member 20a is opposite hand to 20. The upper end of legs 48 and 48a of the members 20, 20a are inwardly offset to engage the face 21 of upper sash member 17. The lower ends of legs 49, 49a overlap the end face of lower sash member 18.

As best shown in FIG. 3A the sash may be custom made to any desired length. Additionally certain lengths and widths of sash have been more or less standardized in the industry and several lengths of the members 17, 18 of such standard sizes may be assembled end to end to provide any desired length of sash to be handled as a unit, in opening and closing for ventilation. In such instances end members 20, 20a may be deleted at the intermediate joints and the adjacent ends of lower sash member 18 may be connected by a suitable splice member 50. Member 50 preferably of angle shape having one leg 51 overlying bottom sash portion 29' and a shorter leg 52 embracing the inner end of portion 29. For splicing the top sash member 17, the splice plate 50 may be omitted since web 38 of the member 36 secured thereto serves the same purpose.

The corrugated plastic panels 35 extending between the top and bottom sash members 17 and 18 are sealed therewith by any suitable form of conventional closure strip conforming to panel corrugations. As shown in FIG. 4,

the portions 22, 26 of the top sash member 17 freely receive the overall thickness of the corrugated panel 35 and suitable elastic sealing strips S can be inserted between sash portions 21, 25. Similarly a conventional sealing strip can be employed with the bottom of the plastic panel. Here the sealing strip 53 at the base of the panel has partial support upon the sash portion 31 and is secured to the bottom sash member 18 by the fasteners attaching the panel to portion 32 of the sash member.

The suspension of the sash, for pivotal movement is best shown in FIGS. 2, 4 and 5. The arcuate portion 23 of sash member 17 substantially conforms to the contour of portion 16 of hanger member 7. As the sash swings to the left of the positions shown in FIGS. 2, 4 and 5, sash portion 23 rotates upon hanger portion 15 and the inner end of the sash portion moves upwardly relative to the arcuate portion 15 of the hanger member 7. Hence any accumulation of dirt, etc., upon the inner face of said portion 15, cannot impede free movement of sash portion 23. The dirt guard 14 overlapping sash portion 23 tends to prevent entrance of dirt onto the inner face of hanger portion 15. Since the dirt guard 14 or 14a is free to pivot upon its connection with member 7 or 7a, no appreciable resistance is offered thereby to free pivotal movement of the sash.

As best shown in FIG. 4, it is desirable to limit the inward movement of the sash as it moves from open to closed position. One suitable adjustable means for this purpose is the screw-threaded members 58 mounted in portion 21 of sash member 17 and spaced longitudinally thereof. The head portion of the members 58 by suitable rotation may be adjustably spaced relative to hanger portion 15 to engage therewith and limit closing movement of the sash.

Customarily such top hung sash, of the invention, is provided with means for holding the sash in any suitable spaced relation to the bottom building sill for ventillation purposes. Such means forms no part of the present invention and any conventional commercially available means may be employed for this purpose.
