JOHN BYRKA SQWM) Gain?) BY QM ATTORNEYS United States Patent 3,212,140 WINDOW CONSTRUCTION John llyrka, Pontiac, Mich, assignor to Whizzer Industries llnc., Pontiac, Mich. Filed Dec. 31, 1963, Ser. No. 334,861 1 Claim. (Cl. 20-53) This invention relates to a window construction and more particularly to a window in which the glassed panels are normally fixed or non-movably positioned.

Large, fixed position windows are commonly used in commercial and house construction along with conventional openable windows. The glazed units of the fixed windows can be cleaned only from the outside of the building and thus, considerable expense and labor is required for outside cleaning purposes.

Hence, it is an object of this invention to provide a window construction of the fixed glazed type, that is, normally not openable, but which window may be opened and pivoted inwardly of the building for cleaning the outer surfaces of glass from inside the building.

A further object of this invention is to provide such a fixed-removable window construction wherein the parts are normally tightly sealed together, but may be easily released and pivoted inwardly and wherein simple extrusions may be used for the various frame and sealing parts.

These and other objects and advantages of this invention will become apparent upon reading of the following description, of which the attached drawings form a part.

In these drawings:

FIG. 1 is a cross-sectional, elevational view of the window construction with the glazed unit in its normal closed position.

FIG. 2 is a view similar to FIG. 1, but showing the glazed unit pivoted inwardly for cleaning purposes.

FIG. 3 is a horizontal cross-sectional view, plan view, taken in the direction of arrows 33 of FIG. 1.

FIG. 4 is a fragmentary, perspective, exploded view of the parts included in the sill and lower frame member.

FIG. 5 is a fragmentary, exploded, perspective view of the locking mechanism and FIG. 6 is a plan view of the locking cam, per se.

The window construction herein is adapted for mounting within a conventional window opening 10 in a wall, shown schematically. The window includes a fixed frame 11 secured to the building within the window opening 10 and formed of a header 12, jambs 13 and a sill 14, all joined together at their adjacent ends in any conventional manner, to form a rigid outer frame.

The jambs and header are provided with

integral flanges

15 and 16 respectively, which extend inwardly of the window opening and secured to the inner (relative to the building) surfaces of these flanges are resilient, continuous strips 17.

The sill 14 (see FIG. 4) is provided with an upwardly opening round bottomed, groove 18 adjacent the inner face of the window unit, the groove being formed of a pair of upwardly extending flanges, namely, a short inner flange 19 and a higher outer flange 20. The sill upper surface 21 slopes downwardly and outwardly of the building and is formed with a shoulder 22.

Fitted within the fixed frame 11 is a framed, glazed panel 24 having an upper frame member 25, side frame member 26 and a lower frame member 27 upon which is formed an inner depending flange 28 terminating in a lower, rounded bead 29 which is widened in the inner direction and which fits into and conforms to the rounded bottom of groove 18 of the sill. The lower frame member also has an outer depending flange 30 which terminates in a downwardly opening groove 31 within which a padding strip 32 is secured. The padding strip has an upper portion which corresponds in shape to the groove 31 and is frict'ionally held within the groove, and a lower, hollow padding portion which rests upon the sloping surface 21 and presses against the shoulder 22 of the sill 14. The padding strip is formed of a resilient rubberlike material, such as a resilient vinyl plastic, extruded into the shape shown.

The frame members each have flanges 35 which are co-planar and extend inward of the window opening and against these flanges is located the glass glazing unit 36 which as illustrated, may be in the form of a pair of glass panes secured together, with an air space between them. The glazing unit, is held in place by means of a continuous glazing strip =37 having an integral leg 38 fitted into a glazing strip channel 39 for-med in each of the frame members. The glazing strip is provided with a groove 41 which receives a padding strip 40, preferably identical to the previously described padding strip 32. The glass unit is thus clamped between the padding strip 40 and resilient stripping 42 secured to the flanges 35.

When the window is in its normal, closed, position (see FIG. 1), the weight of the glazing unit is concentrated near the outer face of the frame and primarily rests upon the outer flange 30 to thus compress and tightly seal the padding strip 32 against the sill.

Locking means are provided to lock the frame panel within the fixed outer frame (see -FIGS. 3, 5 and 6). Thus, the side members of the frame panel are formed in a channel shape formed of an outer Wall 45 and an inner wall 46 with a cross-wall 47. An extruded block 48 having screw holes 49 is screwed to the cross wall 47 by self-tapping screws 50. The block is provided with a journal opening 51. A cam 52 is arranged along side of the block. The cam is formed as a one-piece stamping having a cam plate portion 53 and an integral axle portion 54, which fits into the journal opening 5 1 in the block. In addition, a wrench opening 55 is formed in the cam plate portion and is aligned with a drilled opening 56 is the wall 46 to receive a conventional wrench for turning the cam. The cam, when turned to its locking position, is received within a channel 57 formed in the fixed frame j ambs.

Operation In operation, the fixed frame 11 is permanently secured within the window opening 10 and the frame panel is secured in its closed position (see FIG. 1) by the earns 52. When it is desired to open the window for cleaning purposes, the earns 52 are rotated by wrenches extended through the openings 56 in the side members and the frame panel is pulled inwardly, pivoting about its lower bead 29 which rotates upon the curved bottom surface of the sill channel 18. Preferably, a limiting chain 60 is secured at one end to the frame panel and at its other end to the outer frame to limit the inward movement of the glaze panel to the position shown in FIG. 2. At this point, a window cleaner, inside the building, can reach around the window and clean the outside surface of the glass. Alternatively, the entire fnamed inner panel can be lifted out and removed, although because of its usual large size and weight, this normally would be done only for repair purposes.

After the window is cleaned, it is tilted back into its closed position, pivoting about the bead again and the weight of the glass thrusts downwardly upon the padding strip 32 to seal the padding s t-rip. At the same time, the window is pushed outwardly to tightly compress the sealing strips 17 against the flanges 35 of the jambs and header and at this point the cams are rotated into locked position. The resilient biasing action of the strips 17 tends to push the fnamed panel inwardly to both tightly seal against the framed panel and also press and frictionally locks the side or inner face of the cam portion 53 against the adjacent portions of the jamb channels 57. This provides a tight, rattle-free connection.

This invention may be further developed within the scope of the following claims. Accordingly, it is desired that the foregoing description be read as being merely illustrative of an operative embodiment of this invention and not in a strictly limited sense.

I now claim:

In a window consruction having an inner and an outer face, comprising a fixed frame having a horizontal outwardly and downwardly inclined stepped sill whose lower step is outside the higher step;

and an inwardly swingable framed panel fitted within the fixed frame and having a lower horizontal frame member rested upon the sill;

an upwardly opening horizontally extending groove formed in the sill at the inner face of the window by; a pair of closely spaced upwardly extending parallel flanges;

an inner integral flange depending from the lower frame member near said inner face of the window and terminating in a lower rounded edge fitted within said groove and rested upon said groove bottom; an outer integral flange depending from said lower frame member near said outer face of the window;

and a resilient sealing strip secured to and extending the length of said outer flange for resting upon the outer step of said sill and against the vertical surface between the steps;

said framed pane-l being swung inwardly upon its lower rounded edge for access to its outer surface;

a glazing panel in the fname of the framed panel arranged directly above th sealing strip; with the parts being so arranged that the center of gravity of the framed panel is nearer its outer face for supporting the bulk of the panel weight upon said padding strip;

said sealing strip being in the form of a resiliently compressible hollow sealing strip which compresses under the weight of the framed panel for sealing to the outer step of the sill and the vertical surface between the steps.
