4 Claims. Cl. 189-67) This invention relates to windows of the louver or awning type, and more particularly to improved means for mounting the swinging sashes and opening and closing them. Windows of this character have a tier of sashes in the open area of a rectangular frame and they are adapted to swing upwardly and outwardly from closed positions in a single vertical plane when an operating member on the inside of the frame is actuated.
The invention contemplates a window of this type in which the hinges at the upper corners of the sashes have a vertical sliding movement as the sashes swing in their opening and closing movements, and one object ofthe invention is to provide an improved mounting and actuating means for such sashes which will enable the sashes to be more efiectively moved and held in their fully closed positions without applyingundue force from the operator to the linkage.
Another object is to provide a sash mounting and actuating means of the above indicated character which is strong and sturdy in construction, capable of being manufactured at a relatively low cost, and highly effective in use.
Another object is to provide in a mechanism of this kind a very simple means to permit the sashes to be readily ad justed relative to each other and to the frame, so that the sashes will close tightly against the frame and contiguous sashes against each other.
With the above and other objects and advantages in view, the invention resides in the novel combinations and arrangements of parts and the novel features of construction hereinafter described and claimed, and illustrated in the accompanying drawings which show the present preferred embodiment of the invention.
In the drawings:
Fig. 1 is a vertical sectional view through a window showing the sashes in partially opened positions, parts being broken away;
Fig. 2 is a similar view on a slightly enlarged scale showing the sashes in closed position, parts being broken away and omitted, and the two sashes being shown partly in section and partly in edge elevation;
Fig, 3 is an enlarged horizontal section through the frame and one of the sashes in its closed position with parts being broken away, the plane of the section being indicated by the line 33 in Fig. 1;
Fig. 4 is a detail view of the left hand side of the front oroutside of the frame with parts broken away and with the sashes omitted to show the arrangement of the sash operating linkage;
Fig. 5 is a detail vertical section through a portion of one jamb and a slidable hinge member for a sash, the plane of the section being indicated by the line 5-5 in Fig. 3;
Figs. 6 and 7 are respectively a side view and an edge view of one of the sash hinge members which are fastened to the upper corners of the sash;
Figs. 8 and 9 are detail sections taken respectively on United States Patent 0 "Ice line 8-8 and 9-9 in Fig. 1 to show the adjustable pivot member or bracket for a sash supporting or fulcrum link;
Fig. 10 is a perspective view of the plastic slide shown in Fig. 5;
Fig. 11 is an enlarged vertical front-to-rear sectional view through the lower portion of the sill and of the jamb in which the screw and traveling nut operating mechanism is mounted; and
Fig. 12 is a detail front elevation on a reduced scale of the lower portion of the outer side of the frame.
Referring more in detail to the drawings, the numeral 15 denotes a rectangular window frame which may besuitably mounted in a wall 16 of any desired construction and within the open portion of which is a tier of sashes 17 mounted for both sliding and swinging movement. While only two sashes are shown, a greater number may be used. The frame 15 has a lintle 18, a sill 19 and jambs 20 and 21. All of these parts are preferably of hollow formation and made of suitably united sections of metal such as aluminum, some of which are extruded with grooves or undercut channels. The rectangular sashes 17 are also preferably made of suitably united aluminum sections of the Z-bar type, and each has a glass pane 22 fastened by putty 23 or other means.
Each sash is hung near its upper corners for outward swinging on a pair of longitudinally alined pivots 25 and these pivots are mounted for sliding movement in vertical guides 26 in the jambs 20 and 21. The two or more sashes are connected for simultaneous swinging on the pivots 25 and vertical sliding, by vertical travel links 27 in the hollow jambs and simultaneously actuated by a mechanism in the sill and lower portions of the jambs as hereinafter described. At the side edges or ends of each sash the alined fulcrum links 28 are pivoted at oneend to the sash and at the other end to the jambs, the arrangement being such that the links 28 will cause the sashes to swing on the pivots 25 as the latter are caused to slide vertically in the guides 26 by the movement of the links 27. These guides, as shown in Fig. 3, are undercut channels formed by opposed L-shaped flanges 29 on the inner faces of the outer walls of the hollow jambs. The flanges extend continuously from a point near the top of the jamb to a point spaced above the sill, as seen in Fig. 3. They are formed when the jamb sections are extruded, and the portions of the flanges 29 not needed are cutaway. The pivots 25 are of metal and project through the open portions of the guide channels 26 from enlarged base portions or blocks shaped to slide freely in the channels. If desired the enlarged inner portions of the pivots may be set in blocks 30 of phenolic resin or other plastic shaped to slide between the under portion of an end section of a sash. The arm 34 is short and extends in a direction substantially at right angles to the length of the arm 33. The arm 34 extends in overlapping relation to the adjacent travel link 27 and has an opening 37 to receive a pivot stud 38 carried by that link. The arm 34 is laterally offset from the portion of the plate having the pivot opening 31, and the straight portion of the arm 33 is still further offset in the same direction to properly dispose: these parts in the hollow jamb. Power transfer links 40, later de- Patented Oct. 11, 1955.
scribed, are mounted on the pivot studs 38 associated with the lower sash and are disposed between the transfer links and the arms 34, as shown in Fig. 4. Spacing washers 41 are on the studs 38 associated with the upper sash between the transfer links and the arms 34 as shown in Fig. 3. These parts are removably retained on the studs 38 and the plates 32 are removably held on the pivots by spring clips engaged with grooves in the projecting ends of the studs and pivots as shown in some of the figures of the drawings.
The fulcrum links 28, which cause sashes to swing as the slides carrying the pivots 25 move up and down in the guide channels 26, have their upper ends suitably pivoted to the ends of a sash and their lower ends mounted on pivots 43 which are vertically adjustable on'the jambs. The upper ends of the links 28 of each pair .are preferably'mounted on pivots 44 formed by rivets set in laterally offset portions 45 of the arms 33 of the plates 32. These plates thus serve several purposes and not only simplify the structure but reduce the cost of manufacture. The pivots 43 are pins carried by cast bracket members 46 slidably adjustable in the guide channels 26. The brackets 46, as seen in Figs. 8 and 9, comprise fiat and elongated plates with their edges slidable in the undercut flanges 29 and arms 47 which are offset from the intermediate portions of the plates and project in a forward direction. The pivots 43 are studs which project laterally from the arms and are retained in pivot openings in the links 28 by spring clips. The plates are freely slidable in the flanges 29 and may be fastened in adjusted positions by screws 48 threaded through their end portions and adapted to thrust against the bottom of the guide channel 26. This construction permits quick and easy adjustment of a sash by merely loosening the screws, relocating the pivot carrying member or bracket and then tightening the screws.
It will be seen that the above described structure will enable the sashes to be more eifectively moved and held in their fully closed positions without applying undue force from the operator to the travel links 27, since the latter are laterally off-set in the jambs from the guides 26, 29 which cause the sash fulcrums 25 to move vertically, the arms 47 to which the lower ends of the fulcrum links 28 are pivoted project laterally from the guides in the direction of the travel link, and the short arms 34 of the bell-crank plates also project laterally from the guides and the sashes. Thus when the travel links are moved upwardly force is applied to the laterally projecting arms 34 which are rigid with the sashes and disposed adjacent the pivots 25 thereof, and the bottoms of the sashes will be more effectively forced to .closed positions. That operation is facilitated by having the pivots 43 for the lower ends of the fulcrum links 28 off-set from the plane of travel of the sash fulcrums 25.
. While any suitable mechanism may be provided for simultaneously sliding the travel links 27, I have shown the lower ends of the links 40 pivoted to power arms 50 projecting radially from a torque shaft 51 mounted in the sill. The arm 50 at the right hand side of the frame has pivoted to its intermediate portion a pair of links 52, the opposite ends of which are mounted on pivot studs on a nut 53 adapted to travel on a vertical screw 54. .The latter is on a shaft 55 journaled in hearings on a. casting 56 disposed in an opening in the inner .or front wall of the jamb 20. This casting is fastened by screws 57 to a cast casing 58 fastened by screws 59 to the front of the jamb as seen in Fig. 11. Fixed to the lower end of the screw shaft is a beveled gear 60 in mesh with a similar gear 61 fixed to a forwardly extending shaft 62 journaled in the casting 56 and projecting through the casing 58. A hand crank 68 is removably fastened to the shaft 62 for operating the screw shaft andv causing the nut to travel on the screw. On the casting 56 is a bearing for one end of the torque shaft 51, the other end of which is mounted in a bearing in the sill beneath the other jamb 21. A snap-in resilient sheet metal cover 66, as shown in Fig. 2, closes the open portion of the sill above the torque shaft. A drip cap 64 may be provided at the front of the lintle. Rubber weatherstrips 67 may be provided around the opening in the frame for engagement by the sashes, and a similar strip may extend across the top of the lower sash. These strips are set in grooves in the extruded sections composing the frame and sashes.
From the foregoing, taken in connection with the accompanying drawing, it will be seen that novel and advantageous provision has been made for carrying out the objects of the invention, and while preferences have been disclosed, attention is invited to the possibility'of making variations within the scope of the invention as claimed.
