4 Claims. (Cl. 2li-@11) This invention relates to window structures of the sashless type.
A general object of this invention is to provide a sashless window which is simple in structure, economical to produce, convenient and effective in operation, and lfully in accordance with present day building standards.
Another object is to provide a sashless window having an improved handle structure for opening and closing the window, such handle structure being easy and inexpensive to apply to the window, and `having a fully positive locking means associated therewith.
Another object is to provide a sashless window having improved glass panel bearing channels.
Another object is to provide a sashless Window having improved panel clamping means.
The invention will be described with reference to the accompanying drawing, in which Figure 1 is a side elevation of -a window structure in accordance with the invention,
Figure 2 is a cross-sectional View ure l,
Figure 3 is a partial cross-sectional view on line 3--3 of Figure 2,
Figure 4 is a partial cross-sectional view on line 4 4 of Figure 2,
Figure 5 is a side elevation of a panel clamping mechanism,
Figure 6 is a plan view, partly in section, clamping mechanism,
Figure 7 is a partial sectional plan view showing a handle and locking means,
Figure 8 is a side elevation of the handle means,
Figure 9 is a partial sectional plan of an alternative locking means and handle, and
Figure l0 is a side elevation of the locking means and handle of Figure 9.
In the drawing, the window assembly illustrated comprises a wood frame 1 having sill 2, jambs 3 and 4, and head piece 5. Two pairs of sashless glass panels 6 and 7 and 8 and 9 are mounted in the frame. Since panels 8 and 9 constitute the double or storm window portion of the structure and since their mounting in the frame is substantially identical with that of panels 6 4and 7, only the mounting for the latter panels will be speccally referred to in the ensuing description.
The sill 2 has a groove or channel 10 for reception of the edge portion of glass panel 6. Groove 10 has a rearwardly oifset portion 11 for reception of the edge portion of glass panel 7.
It will be apparent that, in the normally closed posi- 'on of panels 6 and 7, their meeting edge portions will overlap as clearly shown in Figures l and 2. Preferably, groove 10 is provided with channel strips 12 and 13 of suitable semi-rigid plastic composition such as polyethylene, such strips being in longitudinal alignment with their end edges in substantial abutment. Strip 12 extends over the bottom side surfaces of offset portion 11 and the ad- `on line 2-2 of Figof said panel and locking vshoulder 15 defining the end of offset groove portion 11.
The channel strips 12 and 13 provide smooth wear resisting surfaces for engagement with the glass panels 6 and 7 and ensure ease of sliding movement of the panels as well as effective sealing engagement of the panels with the sill during the life of the window. Preferably, the groove 10 and portion 11 `are provided with corner notches 10a to receive the edge portions of strips 12 and 13 and thus provide retaining means therefor. Preferably also, the bottom surfaces 12a and 13a of the channel strips are inclined downwardly from back to front inorder to urge the glass panels into close fitting engagement.
Rib 14 terminates inwardly in slightly spaced relation to the adjacent edge of glass panel 6 in the closed position thereof and its end edge surface 16 is inclined and bevelled, as shown, whereby, when such adjacent edge of glass panel 6 engages the same during opening movement of the panel, the surface 16 will exert :a camming action on the panel 6 to move it out of engagement or into loose engagement with panel 7 and thus permit easeof opening movement.
Head 5 is also provided a complementary groove 17 to receive the upper edge portions of panels 6 and 7. A portion of groove 17, as indicated at 18, is of suliicient depth to permit raising of each panel 6 and 7 a suicient distance to disengage it from groove 10 and thus permit removal of the panel from the frame.
Each jamb 3 vand 4 is provided with a groove 19 communicating with grooves 10 and 17 for reception of the side edge portion of a respective panel 6 and 7. Preferably, each groove 19 is provided with a weatherstripping channel 20 formed of rubber, resilient plastic composition or the like. The channel 20, las shown, has a rib 21 extending inwardly from its bottom wall.
Means for importing sliding opening and closing movements to panel 6 comprises a handle structure 23. Handle structure 23 includes a U-shaped member 24 arranged to embrace an outer edge portion of panel 6. The member 24 is mounted on the panel by means of a plastic strip 25 which firmly bonds the member 24 to the panel. The inner surfaces of member 24 may be serrated as indicated at 26 to firmly lbond the strip 25 thereto. rThe member 24- has a manually engageable handle 27 projecting therefrom. Member 24 may be formed of metal, plastic composition or other suitable material.
Means for clamping the panels 6 and 7 in closed or partially open position comprises a clamping bracket 28 having ya base plate 29 adjustably mounted on sill 2 as by means of screws 30 extending through slots 31 in the plate 29. Pivoted at 32 to the base plate is a clamping knob 33 having a projection 34 provided with a nonmetallic tip 35 for engagement with the panel 6. The tip 35 may be made of plastic composition such as polyethylene and is provided with a rearwardly extending shank 39 which is rigidly and frictionally seated in a socket 40 in knob 33. The knob 33 has manually engageable curved surfaces 36 for easy manipulation thereof. A stop 37 carried by the base plate is engageable by knob 33 to define the locked position thereof. It will be apparent that, by rotating knob 33 to swing its tip 35 out of engagement with the glass panel, the latter is freed for sliding movement. To lock panels 6 `and 7 together, it is simply necessary to swing the knob to apply pressure on panel 6 and thus press panel 6 into clamping engagement with panel 7.
The sill 2 is provided with the usual drainage passages 38.
Means for positively locking the panels 6 and 7 in closed position is associated with the handle structure and comprises a latch 41 pivotally mounted on jamb 4 by means ofa bracket 42 which has a stop 43 dening the open position of the latch. The latch is niounted'in 'lat erally opposite relation to the handle member 24 and has a handle portion 44 and end portion 45 for engagement with a shoulder 46 on member 24. While the shoulder 46 is shown as projecting from the body of member 24, it will be understood that it may, if desired, be recessed within the body.
Referring to Figures 9 `and 10, `alternative means for locking panels 6 and 7 in closed position comprises a spring-loaded latch 47 mounted in 'bracket 48 secured to jamb 4. Latch 47 is engageable by a shoulder 49 on member 24. A lever 50 pivotally mounted in bracket 48 is connected to latch 47 for manual release of the same.
We claim: Y

In a sashless window structure having a wood frame, said frame comprising a sill, jambs and head, said sill having a glass panel receiving groove therein, a glass panel track comprising a channel strip of plastic composition having bottom `and side walls engaging the bottom and side walls of said groove, and a longitudinally extending rib on said strip between and in parallel spaced relation to the side walls thereof, said rib extending from one end of said groove and terminating at a point adjacent the midsection thereof, said rib dividing a portion of said channel strip into two parallel paths of panel movement, the remaining portion of said channel strip being undivided to provide a single path of panel movement.
2. A sashless window structure as deiined in claim l, said channel strip having a longitudinally extending rib projecting outwardly from the exterior surface of each side wall thereof and laterally opposite the bottom wall thereof, said groove having notches each receiving one of said last mentioned ribs.
3. A sashless window structure as dened in claim l, said single path having a greater width than each of said rst-mentioned parallel paths.
4. A sashless window structure as defined in claim 1, said channel strip comprising two sections in end-to-end abutting relationship, said rib being located in one onlyl of said sections and terminating in spaced relation tot the end thereof abutting said other panel.
