United States Patent WINDOWS Edouard Clerk, St. Hilaire, Quebec, Canada Application October 23, 1951, Serial No. 252,609
4 Claims. (Cl. 20-565) This invention relates to windows and provides an improved double-glazed sash assembly which, while use ful in various other types of window frames, is particu larly adapted for window installations of the type de* scribed and claimed in my co-pending application Serial No. 161,864, filed May 13, 1950, now abandoned.
One object of the invention is the provision of a doublemovable inner glazing pane is secured in place so that the indoor side of the sash frame presents substantially the same appearance as an ordinary single-glazed wooden sash frame and is free of the unsightly exposed hinges, fastening devices and other hardware elements which are positioned at the indoor side of conventional types of double-glazed sash frames in which the inner sash is carried by a supplementary sash frame fitted in a recess provided in a main sash frame in which the outer glazing pane is permanently secured.
Other objects, advantages and characteristic features of the invention will be more readily understood from the following detailed description taken in connection with the accompanying drawings, in which- Fig. 1 is a perspective view looking toward the outdoor side of a double glazed sash assembly embodying my invention.
Fig. 2 is a perspective view of the double glazed sash assembly as it appears when looking toward the indoor side thereof.
Fig. 3 is a vertical sectional view showing the invention embodied in upper and lower sashes adapted to be arranged in a window frame (not shown) of the sliding sash type. i
Fig. 4 is a fragmentary exploded view illustrating the manner in which a section of the top rail of the sash frame is removable to facilitate removal and replacement of the indoor glazing pane of the sash assembly.
Fig. 5 is a fragmentary plan view illustrating the manner in which a sealing strip employed for sealing and securing the indoor glazing pane in place is applied and Fig. 6 is a sectional view taken along the line 66 of Fig. 5.
As shown in these drawings my improved double glazed sash assembly comprises inner and outer glazing panes 5 and 6 mounted in a single sash frame 7 so that the inner pane 5 is readily removable to facilitate cleaning and replacement thereof and, also, to facilitate cleaning of the indoor side of the outer pane 6.
Sash frame 7 is provided with a centrally located parting strip 8 extending across the uper surface of the bottom rail 9 and upwardly along the inner surface of 2,719,341 Patented Oct. 4, 1955 the side rails 10. The top rail 11 is divided vertically into a pair of sections comprising a permanently fixed main section 12 and a removable auxiliary section 13. The main top rail section 12 is permanently fixed to the upper ends of side rails 10 which have their lower ends permanently fixed to bottom rail 9. The auxiliary top rail section 13 is removably secured to the main top rail section 12 by any suitable securing means such, for example, as the fastening screws indicated at 14.
The main top rail section 12 of sash frame 7 is provided with a downwardly opening groove 15 extending across the lower surface thereof so that the indoor side wall of said groove is flush with the outdoor sides of parting strip 8. The outdoor glazing panel 6 is arranged in frame 7 with its upper marginal portion fitted in groove 15 and its side and lower marginal portions seated against or positioned close to the correspondingly located portions of parting strip 8. This glazing pane 6 is secured in place in any suitable manner such, for example, as by means of the putty indicated at 17. t
The bottom and side rails of sash frame 7 are grooved to provide a U-shaped glazing receiving channel 19a presenting a horizontal portion 19 formed in the bottom rail 9 and vertically extending portions 20 formed in the side rails 10 and open at their upper ends. This glazing channel is formed in the rails 9 and 10 so that its outdoor side wall is formed by the indoor side of parting strip 8. The inner side walls of the portions 19 and 20 of the glazing-receiving channel are recessed as indicated at 21 to receive a glazing-pane sealing and retaining strip hereinafter referred to.
The removable top rail section 13 of sash frame 7 is provided with a rib-like projection 22 fitted in a recess 23a of the complementary main top rail section 12 to hold these two top rail sections against: relative vertical displacement. The removable top rail section 13 is also provided with a groove 23a forming the top and indoor side walls of a glazing receiving channel 24 whose outdoor side wall is formed by the indoor side wall of the main top rail section 12. The indoor side wall of groove 23a is provided with a sealing strip receiving recess 25 corresponding to and connecting the upper ends of the recesses 21 of side rails 10.
The indoor glazing pane 5 is mounted in the sash frame 7 in the following manner: The screws 14 securing together the top rail sections 12 and 13 are first removed and the auxiliary sash rail section 13 is then separated from main rail section 12 so that the transparent pane 5 may be fitted in the sash frame by sliding the lateral marginal portions of said pane downwardly in the side portions 20 of the glazing receiving channel until the lower portion of said pane is seated in the bottom portion 19 of the glazing channel. The auxiliary top rail section 13 is then reassembled with the main top rail section 12 and secured in place by the screws 14 so that the upper edge of the pane 5 is housed within the top glazing channel 24 formed by and between the rail sections 12 and 13. At this point it is important to note that the widh of the glazing channels 19a and 24 is considerably greater than the thickness of the sash pane 5 so that the latter is a loose fit in said glazing channels. The pane 5 is secured in place and hermetically sealed by means of a continuous sealing strip 27 which is forced between the indoor side of the pane 5 and the opposing indoor side walls of the glazing receiving channels 19a and 24 so that said sealing strip is seated in the recesses 21 and 25 and thereby securely held against casual displacement. The sealing strip 27 may be progressively forced into place with the aid of a suitable tool 28 as illustrated in Figs. 5 and 6.
When it is desired to remove the glazing pane 5 this is accomplished by separating the auxiliary top rail section 13 of the sash frame from the main top rail section 12 and just sliding the pane upwardly ,within the U- shaped glazing receiving channel 19a formed in the side rail and bottom rail 9. This removal of the glazing pane 5 is facilitated by removing the sealing strip 27 immediately following the separation of the auxiliary top sash rail section 13 from the main top rail section 12.
While double glazed sashes of the type embodying my invention may be used in various types of window frames they are particularly useful when used as the outer and inner sashes of a window assembly of the type disclosed in my co-pending application Serial No. 161,- 864, filed May 13, 1950, now abandoned. In that application I have disclosed a window assembly in which upper and lower sashes are interconnected by flexible elements so that they counterbalance each other and in which the construction of the window frame and the method of connecting the flexible elements to the sashes is such that each of the latter, when moved to its lowermost position in the window frame, may be pulled into the room and turned about a horizontal pivotal axis to facilitate either the removal of the sashes or the cleaning of the indoor and outdoor panes. When the sashes disclosed in such application are replaced by double glazed sashes embodying the present invention it will be seen that the removal of the sashes, the reversal thereof about a pivotal axis to facilitate cleaning the exposed sides of the indoor and outdoor panes, and the removal and replacement of the indoor glazing panes of both sashes may be conveniently accomplished by a person standing on the floor at the indoor side of the window frame.
The removable top rail section 13 of each sash is preferably provided With a substantially circular longitudinally extending sealing-strip receiving groove 30 located below and immediately adjacent the rib 22. A sealing strip 31 is secured in place in groove 30 and projects therefrom so that said sealing strip is compressed against the opposing surface of the main top rail section 12 when the two top rail sections are in the assembled relation shown in Fig. 3.
Having thus described the nature of my invention and a preferred embodiment thereof, it will be understood that various modifications may be resorted to within the scope and spirit of the invention as defined by the appended claims.
