3 Claims. (Cl. 20-48) This invention relates to windows. More particularly, the invention is a window including an inner, pane-supporting frame hinged to swing inwardly of the building to facilitate cleaning.

Conventional windows, whether of the double hung, casement, or some other type, are difficult to clean since the pane is mounted in a frame that either swings outwardly of the building, or is slidable horizontally or vertically. Due to these conventional arrangements, one cleaning a window from inside the building must place himself in an uncomfortable, inconvenient, and in fact a precarious position, seated on the sill with half his body outside the window.

In eliminating this deficiency in conventional window design, the present invention includes an outer sash frame, shiftable in the manner of conventional frames between open and closed positions, and an inner frame carrying the pane and hinged to the outer frame to swing inwardly of the building structure. One is thus enabled to clean opposite faces of the pane from inside the house, without inconvenience, discomfort, or danger, and without shifting of the outer frame from its normal, closed position. An object of importance is to not only facilitate the cleaning of the window, but also permit the improved window to be mounted in a conventional window frame without modification of said window frame. The improved window can thus be used as a substitute for windows already in use.

Another object is to secure the above noted advantages without material increase in the cost'of manufacture of the window.

A further object is to obtain the desired results without detracting from the appearance of the window.

Yet another object is to provide, in association with the outer and inner sash frames, sealing strips carried thereby capable of being compressed when the inner frame is closed to prevent vibration of the inner frame and to further prevent leakage or drafts between the contacting surfaces of the inner and outer sash frames.

A further object is to so design the sealing strips as to eliminate the need for puttying the window pane in place.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 is a front elevational view of a window formed in accordance with the present invention, seen from within the building.

Fig. 2 is a vertical sectional view on line 2-2 of Fig. 1, on an enlarged scale.

Fig. 3 is a detail sectional view, still further enlarged, on line 33 of Fig. l.

Fig. 4 is a detail sectional view, on an enlargedscale,

rates Patent 2,776,459 Patented Jan. 8, 1957 on line 4-4 of Fig. 1, showing the lock of the inner sash frame member.

Fig. 5 is a sectional view, still further enlarged, on line 55 of Fig. 4.

Fig. 6 is an enlarged sectional view, similar to Fig. 4, showing a modified form.

Fig. 7 is a sectional view similar to Fig. 6, but on a scale still further enlarged, the inner frame being closed.

Fig. 8 is a fragmentary perspective view of the modified inner frame.

The reference numeral 10 designates a building wall, having a window opening in which is fixedly mounted a rectangular Window frame 12 including side jambs 14, a header l6, and a bottom piece 18. A sill 20 projects interiorly of the building in coplanar relation to bottom piece 18, and an apron 22 depends from the sill in contact with the inner surface of the room wall. All this is conventional and does not per se constitute the invention. However, it is of importance that the improved window constituting the invention is mountable in a wholly conventional frame 12 already in use, merely by removal of the conventional sashes and substitution of the improved sashes for those removed.

Lower and upper sashes formed in accordance with the invention have been designated generally at 24, 26, respectively. In the illustrated example, a double hung window is shown. However, the invention can be embodied in any type of window in general use, including casement, horizontal sliding, reversible, awning, austral, and basement windows. In every instance the sash, regardless of how it is mounted in the window frame for movement between open and closed positions, and even if fixedly mounted in a permanently closed position, includes an outer sash frame, and an inner, pane-carrying sash frame movable inwardly of the building structure between open and closed positions relative to the outer sash frame.

In the illustrated example, since the window is of the double hung type, there is a parting strip or bead 28, and side strips 3% extending vertically on the inner surfaces of the side jambs, to provide adjacent, vertical trackways for the lower and upper sash frames 24, 26.

Since the frames 24, 26 are identical, only the frame 24 will be described.

The sash frame 24 includes an outer or main sash frame member 34 of rectangular formation, the outer surfaces of the side rails of which are slidably engaged in the associated vertical trackways of the window frame 12. The inner periphery of outer frame member 34 is formed with a continuous rabbet groove 36 of right angle cross section, and mounted in the rabbet groove is an inner sash frame member 38 also of rectangular formation, and also having, on its inner periphery, a continuous rabbet groove 40. A window pane 42 is mounted in the rabbet groove 40, and is puttied in place as at 44.

The inner frame member 38 is hinged to one side rail of the outer sash frame member 34 by hinges 43. These may be conventional butt hinges as shown in Fig. 3. It is of importance that the hinging of the inner frame member 38 is such as to cause said member to swing inwardly of the room, between an open position, and a closed position shown in Fig. 2. When the inner member is swung inwardly, the outer and inner surfaces of the pane 42 can be cleaned, from inside the room, by one standing or seated in the room in a comfortable position. The outer sash frame member 34, of course, need not be shifted from its normal position in the window frame if desired.

Means to lock the inner member 38 in normally closed position is shown in Figs. 4 and 5, and includes a rotatable shank mounted in that side rail of the inner member opposite that to which hinges 41 are connected. The

shank is integral or otherwise made rigid at its outer end with a knob 46 accessible from inside the room to rotate the shank. The inner end of the shank has a reduced projection 48 of noncircular cross section, extending axially of the shank and engaging in a complementarily shaped opening-formed in the inner end of a locking arm 58 of blade-like formation. Arm 56 extends radially of the locking shank, and in the closed, locked position of the inner frame member the outer end of the arm engages in a locking recess 52 formed in the adjacent surface of frame member 34. The inner end of arm Si) is in a recess 54 of the inner member 38, the recesses 52, 54 communicating in the closed position of the inner frame member and having arcuate inner walls merging into one another as shown in Fig. 5.

To open the inner frame member, knob 46 is rotated 90 to shift the arm 54) to a position in which it is confined entirely within recess 54.

In the modification of Figs. 6-8, the modified sash 24 includes an outer frame member 34* having a rabbet groove 36 on its inner periphery. One side of the rabbet groove is closed by an overhang or ledge 56, and engaged in the rabbet groove is a soft rubber sealing strip 58 of L-shaped cross section, the outer surfaces of said sealing strip being perpendicular to one another and being seated H against the perpendicularly related walls of the rabbet groove.

Formed in the sealing strip 58 is a slit 60 which normally is slightly open (Fig. 6) at its outer edge to impart a tapered cross sectional shape thereto. The inner edge of the slit terminates in spaced relation to the point of intersection of the perpendicularly related outer surfaces of the sealing strip. The slit 60 lies in a plane passing through said point of intersection and bisecting the right angle defined by the outer surfaces of the sealing strip.

The slit 6b opens upon the inner surface of the sealing strip. As shown in Fig. 6, normally the sealing strip has the inner surface portions 62, 64, defined at opposite sides of the slit 60, disposed at an obtuse angle to one another, so that the sealing strip can be said to be formed with perpendicularly related legs bisected by the slit, with each leg being thickest immediately adjacent the slit and decreasing in thickness in the direction of its outer longitudinal edge.

A sealing strip 66, also of soft rubber or other readily compresible, resilient material, is applied to the inner sash member 38*, and extends through the full periphery of said inner sash member. Inner sash member 38 has a rabbet groove th receiving pane 42, the sealing strip 66 exte -ding as an overhang adjacent the groove to hold the pane in plane. Thus, no putty is used in the modied form. instead, strip 66, at spaced locations throughout its periphery, has transverse, counterbored, smoothwalled openings 68, reeciving a leg screw 70, threaded into the sash member 38 Sealing strip 66 is formed with obtusely related outer surfaces 72, '74, surface 74 engaging against surface por tion 6d and surface 72 engaging against surface portion 62.

When the inner sash member 33 is in an open position (Fig. 6), strips 58, odexpand. When, however, sash member 33 is swung to closed position, pressure is eX- erted against surfaces '72, 7d inwardly thereof, to compress the 'o 6-6 and form the surfaces 72, 74 into perpendicult. 1, related surfaces (Fig. 7). Surfaces 72, 74, meanwhile exert pressure against the surfaces 62, 64, forcing them inwardly so that they also assume a perpendicular relationship. Slit 6i) closes under the compressing action exerted against strip 53. As a result, a very tight seal is provided between the inner and outer sash members 33 34*, respectively, to. prevent leakage, vibration, or drafts. Further, the arrangement .se-. curely holds the window pane inplace without putty, and it will benoted that in the closed position of the inner sash member, the edge of the window pane is encased securely-in the sash, so as to be prevented from dropping out. The pane is securely held in place by the compressed strips, and it will be noted that the pane is prevented from moving out of its rabbet groove 48 not only by the sealing strips, but also by the outer sash member, which backs up the compressed sealing strips in the area through which the pane would move if it where to tend to drop out of the rabbet groove 40 When the inner sash member is closed, of course, the window functions in the same manner as any conventional window, the outer sash member being shifted upwardly or downwardly in the illustrated example to open or close the window as the case may be. Further, the invention could be embodied in any other type of window, and in each instance, when the inner sash member is swung to closed position, the outer sash member can be opened or closed in the regular manner.

Further, the invention can be substituted for conventional window sashes. In the illustrated example, it may be noted, it would be necessary only to remove the guide strips 23, Stl, 32, to take out the old sashes and substitute the new ones.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
