March 3, 1964 v. SEGRE WINDOW FRAME WITH REMOVABLE wmnows 2 Sheets-Sheet 2 Filed Feb. 8, 1962 I Inventor V. SEGRE ,7 Z Attomjys United States Patent 3,122,797 WKNDOW FRAME W111i REMQVABLE WINDOWS Vaifredo Segre, 3995 Picqnet Road, Montreal, Quebec, Canada Filed Feb. 8, 1962, Ser. No. 172,025 2 Ciairns. (Ci. 28-522) This invention relates to window frames with provision to remove the windows from one side of the frame and particularly to the provision of means whereby the window nearest the removing side of the frame is kept in sliding engagement in its track in any vertical position of the window in the frame.
The invention consists essentially in the provision of cut-out sections in the inwardly projecting walls of both upper and lower window tracks whereby each window can be moved from its normal position to in line with the cut-out sections of their individual tracks for removal. The invention is further characterized in that while the outer or farthest away window is maintained in its track in any vertical position by the inner or nearest window, the nearest window is provided with means whereby it is maintained in its track even when it is positioned opposite the cut-out section of its track. A third inner track can be provided in the window frame to receive a screen element which is also removable, and must be removed before the window elements can be removed from the frame.
The object of the invention is to provide a window frarne having window receiving tracks which permit the windows to slide up and down in confined vertical alignment and having means to permit instant removal of the windows from their frame.
A further object of the invention is to provide means whereby the window elements can be readily removed in the location opposite from their normal position in the frame.
These and other objects of the invention will be apparent from the following detailed description and the accompanying drawings, in which:
FIG. 1 is a perspective view of the inside of a window frame and window elements.
FIG. 2 is a vertical elevation of the window assembly shown in FIG. 1 with the screen element removed and partly in section to show the top guide of the lower window element.
FIG. 3 is a vertical section on the line 33 of FIG. 2.
FIG. 4 is a view similar to FIG. 3 but showing the lower window element partly removed from the frame.
FIG. 5 is a view similar to FIG. 4 but showing the upper window element partly removed from the frame.
FIG. 6 is an enlarged partial section of the lower right hand corner of the window frame and lower window element and the spring locking means.
FIG. 7 is an enlarged vertical section on the line 77 of FIG. 2.
Referring to the drawings, the window assembly comprises a window frame 5, an upper window element 6, a lower window element 7 and a screen element 8.
The window frame 5 is shown as having three vertical tracks 6, 7', and $5 on either side of the window frame 5. The track 6 has its inward facing vertical members 9 cut back at 10 to provide an opening of greater horizontal width than the horizontal width of the window 6. The cut back portions 16 extend upwards from the lower end of the track 6' a height greater than the vertical height of the window 6 to permit the window to be removed from the window frame when the window has been lowered to the bottom of its track 6'. The track members 9 are bent at right angles to form the flanges 11 and are cut out at 12 at various positions along their vertical height to receive the latches 13 of the window locks 14, for the 3,122,??? Patented Mar. 3, 1%64 'ice purpose of holding the window in various vertical positions in the window frame.
The tracks 7' are spread apart in the frame 5 a greater horizontal distance than the tracks 6' and the tracks 8 are spread a still greater horizontal distance than the tracks 7'. This enables the window 6 to pass between the tracks 7' and 8' and the window 7 to pass between the tracks 8'.
The tracks 7' have their inward facing vertical members 15 cutback at 16 to provide an opening of slightly greater horizontal width than the horizontal width of the window 7. The cut back portions 16 extend from the upper end of the track 7 downwards to a position below the lower horizontal edge 17 of the window 7 when the top horizontal edge 18 of the window is positioned slightly below the lower edge of the top horizontal member 19 of the frame defining that portion of the track 7 The tracks 7' are provided with the flanges 20 which are notched at 21 to receive the latches 16 of the window locks 14 in the same manner as described above in connection with window 6. In addition the window 7 is provided with a pair of latches 22 at its top horizontal edge 18. These latches 22 engage in the tracks 7 behind the flanges 20 and retain the window to vertical movement in its tracks when the window is located opposite the cut-out portions 16 of the vertical members 15. The latches 22 are provided with detents 23 engaging in one or other of a pair of openings 24 in the bottom wall of the horizontal channel 25, permitting the latches to be held in side channel engaging position to retain the window 7 in the frame while it is located opposite the cut back sections 16 of the vertical members 15 and, when the latches 22 are in the disengaged positions, permitting the window 7 to be removed from the frame when the window is located in the upper part of the frame opposite the cut back sections 16 of the vertical members 15, in the manner shown in FIG. 4.
The screen 8 is vertically slidable in the tracks 8' and is provided with a pair of latches 26 located at its bottom horizontal edge, similar to the latches 14 described above. The latches 26 are engageable in the slots 27 in the side walls 28 of the channels 8. A pair of hook members 29 on the top horizontal edge 36 of the screen 8 also engage in the channels 8. When the latches 26 are withdrawn from the channels 8', the screen can be pivoted out from the frame 5 and given a slight twist to disengage the hook members 2% from the channels 3 for removal of the screen from the frame.
In the above described frame and window assembly, the windows 6 and 7 can be moved along their respective guide channels 6' and 7' into reversed positions to bring them opposite the cut back portions of their guide channels. In this reverse position of the windows, the window 6 is held slidable in its channel 6 by the window 7 to prevent it from being displaced from its guide channel past the cut back portion, while the window 7 is held slidable in its channel 7 by means of the detent latches 22 and so prevents the window from being displaced from its channel past the cut back portion of the channel. The window 7 can be removed from the frame after removal of the screen 8, by sliding the window upwards until its vertical height is opposite the cut back portions 16 of the channels 7. 'In this position, the lower latches 14 are withdrawn from engagement with the channels 7' and the lower end of the window is pulled out from the frame sufiicient for the latches to engage the outer surface of the channel members 15. The upper latches 22 can then be withdrawn from the chanels 7 and are held in their withdrawn position by the detents 23. The window can now be removed from the window frame 5.
The window 7 having been removed, permits the window 6 to be also removed. The window 6 is slid down in its channel 6 until its full vertical height is opposite the cut back portions 10 of the channels 6'. The latches 14 are then Withdrawn from the channels 6' and the window is then free to be removed from the window frame 5 past the members 15 of the channels 7'.
In order to replace the windows and screen in their frame, it is only necessary to reverse the above procedure.
The offsetting of the vertical channels 6, 7 and 8' in respect to each other and the cutting back of a portion of the members It} and 15, permits the insertion and Withdrawal of the windows with a minimum of time and effort, while the simple latches permit the window to he slid up or down in their channels with ease While maintaining the windows weathertight.
What I claim is:
1. In a Window flame assembly, a window frame having two or more inwardly facing window guide channels located in planes adjust to and parallel with each other around the inner periphery of the window frame, the said channels being formed by inwardly projecting flange members, the vertically disposed portions of certain of said flange members having a portion of their length cut back to increase the horizontal width of a window opening in the window frame, an upper outer window memher and a lower inner window member slidable vertically in adjacent guide channels, the upper window member being removable inwardly of the window frame from its guide channel past the cut back portions of its channel flange members at the lower end of the guide channel, and the lower window member being removable inwardly of the window frame from its guide channel past the cut back portion of its channel flange members at 4% the upper end of the guide channel, the said guide channels having a series of apertures spaced apart along their vertical length, a pair of spring latches on the lower horizontal edge of each of said upper and lower windows, the said spring latches adapted to engage in selected apertures in the said guide channels, the said lower window preventing inward movement of the said upper Window past the cut back portion of its guide channel when the said upper window is aligned with the said out back portion, and a pair of detent latches on the upper horizontal edge of said lower Window, the said detent latches maintaining the said lower window in sliding engagement with its guide channel when the said window is aligned with the cut back portion of its guide channel. 2. In a window frame assembly as set forth in claim 1, the said detent latches in the upper horizontal edge of the Window are provided with a two portion detent permit:
ting the latches to be held in the channel engaging position and clear of the said channels.
