BERNARD E. MENDELSOHN BY gal/ff zggfiffiztu ATTORNEYS Elite The present invention relates to a storm window and in particular to a novel construction of a storm window and frame therefor.

The present invention provides a novel structure for a storm window in which there is provided a combination of a storm window and screen. In this structure means are provided by which the window may .be readily disassembled for cleaning purposes. In this operation, side runners for the window sash and screen elements are removed and the window sashes are pivoted inwardly at an angle to the window frame so as to permit an individual to clean both sides of the window pane. in this structure, there is provided a hinging member to facilitate the pivoting of the window pane to a desired cleaning position. This hinging element is so constructed as to permit the window pane to be entirely removed from the frame. Similarly, the screen member may also be entirely removed from the frame, if desired. Such structure will obviously avoid the requirement that windows be cleaned from the outside by sitting on the window sill or by us ing ladders, which operations are, of course, quite dangerous in nature.

The structure of the present invention further provides a unit which is relatively inexpensive to manufacture, but which has a minimum of operative elements, thus, providing a rather fool-proof operation which is quite unlikely to become broken or otherwise inoperative.

The present invention also provides a structure in which the frames and the window panes interengage in a locked position when the panes are closed. To open the window from the inside, the operator need only press the inside window outwardly to disengage the interengaged element and thenslide the window pane upward. A similar interengaging element is used for the screen element and this may also be unlocked by a similar operation. Both the screen and the window pane, however, can not be unlocked from the outside, as there is no means by which the screen or pane may be pressed outwardly from the outside. These and other objects of the present invention will be more clearly understood when considered in connection with the accompanying drawings in which:

FIGURE 1 is a plan view of the invention,

FIGURE 2 is a cross sectional view taken substantially along the line 2-2 of FIGURE 1,

FIGURE 3 is a cross-sectional view showing the invention in an arrangement whereby the window may be pivoted to a cleaning position,

FIGURE 4 is a cross-sectional view taken along the line 44 of FIGURE 1,

FIGURE 5 is a fragmentary perspective of a lower corner of the frame assembly, and

FIGURE 6 is a fragmentary cross-sectional detail of a window sash.

Referring to the drawings, there is illustrated a storm window having an outer frame extending about four sides with each side joined to the adjacent side by suitable teams and preferably at an angle of 45. This outer frame 1 is provided with its lower side or bottom '7 havvided on the flanges 4 and 5 for additionalstrengthening purposes and also to provide channels for uses not coming within the scope of the present invention. The inner end of the flange 5 terminates in an upwardly-extending lip id. There is also provided a hook member 11 which extends upwardly from the central portion of flange 5. The upwardly or vertically-extending flange 2 extends into an upwardly-extending lip 12 which projects upward and beyond the horizontal flange 5. If desired, lip 12 may be provided with a center section 13 having a slight angular bend in .it primarily for purposes of decoration. The frame has sides 14 and 1.5 and a top 16 which are similar in cross section to bottom 7, except that they do not have a hook member 1.1.

Positioned upon the bottom 7 is the locking element 18. This locking element 13 extends from side 14 to side l5 and comprises in cross section two side walls 19 and ing a cross section as illustrated in FIGURE 5. This lower side 7 has in its cross section a vertically extending flange 2 with several horizontally-extending flanges 3, 4

.and 5. The lowermost horizontally-extending flange 3 forms an outside apron of the frame of the storm window with two substantially equal longitudinal 26 interconnected continuously by a top 21 withthe top 21 inclined downwardly towards the outside of the locking member 18. Side 20 is longer than the side 19, while the side 19 is provided with a longitudinally-extending, hook-like flange 22 extending outwardly and downwardly at its base. This locking element 18 is also provided with two upwardly-extending flanges 23 and 24 with the upper ends of the flanges 23 and 24each provided with a barblike upper edge as illustrated at 25 and 26 respectively. These barb- like elements 25 and 26 may extend continuously along the length of the upwardly-extending flanges 23 and 24, or may, if desired, be intermittent in such a manner as to engage with the screen and window pane in the manner hereinafter described.

The locking element 18 has its side walls 19 and 20 of a sufficient and proper length to interengage the sides of the bottom 7. Thus, the flange 22 and side 19 cooperate to engage the upwardly-extending lip 12 at its extreme top end, while the side it extends downwardly to engage the flange 5 adjacent the upwardly-turned lip lid. By this arrangement, locking element 13 may be securely heldin position between the sides 14 and 15 and the lip 12 and pivoted upward for removal when desired. Secured to the sides 14 and 15 are a pair of runners 3i) and 31. These runners are secured between the lips 12 and 10 on the side 1-i and '15 by screws or other suitable means. These opposite parallel runners 3t and 31 are provided channels 33 and 34 formed respectively by the channel flanges 35, 36 and 36, 37. These channel flanges 35, 36 and as, 37 eXtend downwardly to a joint just short of the midpoint of the window frame and provide fixed channel runners for the window panes and shades hereinafter described.

Additional side runners 38 and 39 form continuations respectively with side runners 3d and 31. These side runners 38 and 39 are identical in cross section with the and 39, the tops are preferably bevelled towards the base of the runners, while the bottoms which interengage the locking member 18 are provided with notches 4t and 41 in the rear wall 42 of the side runners. These notches 40 and 41 fit over the upwardly-extending flanges 23 and 24, thus providing a snug and engaging fit between the side runners 38 and 39 and the locking member 18. This engaging fit, however, is such as to permit removal of the side runners 33 and 39 when desired. It is to be noted that the flange 44, which is a continuation of the flange 37, is positioned outside of the flange 24 when the side runners are in position. Flange 45, which is a continuation of flange 36, is aligned with the flange 23; while flange 46, which is a continuation of flange 35, is positioned just inside of flange or lip 12.

Within this frame assembly there is positioned an upper window sash 50, a lower window sash 51 and a screen 52. These elements 50 and 51 are similar in structure to one another and each are provided with a frame having a cross section in the shape of an H. In this structure the cross section has two side legs 53 and S4 and a cross member 55. This cross section is continuous all about the four sides of the frame which enclose the glass panel 56. The glass panel 56 is secured at its edges between the inner portions of the leg 53 and 54. The four elements, having this H cross section which comprise each of these frames, are secured together at their ends which are preferably bevelled at an angle of 45 by any suitable means, such as an L-shaped clip having one leg adjacent the outer surface of the cross member 55 on one side of the frame and the other leg adjacent the outer surface of the cross member 55 of the adjacent side. The ends 102 of this L-shaped clip 101 are bent inwardly in a lip which engage an opening in the surface 55 of the cross member. These clips may be rigidly secured in place by suitable means, such as by punching holes 160 in the leg or side 53 so that the periphery of the hole is flared inwardly engaging the L-shaped clip. The lowermost side of these frames 59 and 51 have their outer leg 54 provided with a barb 59 at their lower edge. This barb 59 is adapted to engage the barb 26 when the lower window sash 51 is in a down and locked position. The lower window sash 51 is tensioned in an inward direction by the spring 60. This spring 60, which is a leaf spring, having its end 61 projecting through the side frames of the window sash in the inner portion of the leg or flange 53. The spring 60 normally engages the inside surface of the flanges 37 and 44 and tensions thereby the window sash 51 inwardly to a point at which the inner portion 63 of the leg 54 of the side portions of the window frame ride in face to face contact with the outer surfaces of the flanges 37 and 44. This arrangement of the window sash 51 and the flanges 37 and 4-4 is identical on both sides of the window. Thus, when the lower window sash 51 is in an up or partially up position, generally indicated by the dotted outline 6 the side 54 of the frame is aligned with the flange 24. When, however, the window sash is pulled all the way down to a closed and locked position, the barbs 59 and 26 engage with one another and are held in this position by the tension of the spring 60. The top window sash is similar in structure and has a similar cross section and spring provision.

This leaf spring on the top window sash 50 tensions against the flanges 3S and 46 in such a manner as to also tension the top window sash in an inward direction. This top window sash is, however, not provided with engaging barbs as is the bottom, as such locking members are not ordinarily necessary for the upper window sashes in a storm window arrangement. the top and bottom window sashes 50 and 51 is the screen 52. This screen is provided with the frame 67, which frame has a cross section as illustrated in FIG- .URE 2. This cross section has parallel leg members 68 and, 69 joined together at their inner end by the cross member 70. A pair of ribs 71 may be provided on Sandwiched between the inner surfaces of the legs 68 and 69 for strengthening purposes. Leg 63 continues inwardly forming a channel 72 between the section 70 and the lip 73. The tip 7? is angularly arranged with respect to the section 70 forming a channel 72 with a restricted opening. The screen which may be made of any suitable material such as aluminum screening has its edges secured within this channel 72 by suitable means which may include a resilient cord member forced into the channel 72 about the periphery of the screen. The lower end of the leg 69 of the bottom cross member of this screen 52 is provided with a barb 74 which is adapted to engage the barb 25 when the screen is in a down and locked position.

This screen 52 is also provided with a spring 77 at each side secured to the screen in a manner similar to that as described in connection with the spring 60. This spring 77 tensions the screen 52 inwardly also in a manner similar to that described in connection with the window sashes 5t) and 51. Thus the screen 52 may be moved from an open or partially open position into a closed and locked position in the manner similar to that described in connection with the locking operation of the top and bottom window sashes 56 and 51. The screen 52 may be locked in an up position, if desired, in the manner similar to that described in connection with the locking of the window sash 59 in an up position.

The above arrangement described provides a structure in which a locking mechanism may be eliminated if desired. It further provides, however, structure in which the window may readily be unlocked by merely pushing the window sash slightly outwardly to disengage the barbs against the tension of the spring and thereafter raising the window sash upwardly until the barbs are no longer engaged with one another.

In the present invention there is also provided a means for pivoting the window sashes from a vertical position to an angular position extending inwardly of the sash so as to readily permit the washing of the inside as well as the outside of the windows. The structure also provides means by which the window sashes may readily be removed for repair or cleaning if so desired. In this structure and operation the locking member 18 is removed fro-m engagement with the sash at the removal of the side channels 38 and 39. When the locking element 18 is removed, the window sashes are then slid downwardly from their up position so that they come into engagement with the hook member 11. In this position, the upper ends of the window sashes are free of the fixed channels 3i} and 31 and are thus readily pivoted into a position as illustrated at 36 (FIG. 3). In this position they may be cleaned or, if desired, removed from the window frame structure to permit repair or more extensive cleaning. In this manner either or both window sashes 50 or 52 may readily be cleaned without the requirement of going outside of the house or structure in which the window is located.
