N14-7n i The present invention relates to improvements Airi1burglar`proof window screens and has particular reference to sash windows. fV i i Theprincipalf object of the invention is topro- Vide a window screen that is actuated by sash movements so as to cover the space left free by a sashopening movement and to automatically retract i or collapse on a sash closing movement which causes the space occupied by the window to'be covered at al1 times, either by the sash itself orby the screen. l `A Vfurther object of the invention is to provide ascreen of the character described which is very rigid and strong in construction, particularly for `thelower sash so as to make it difficult for a burglar tobreak the same or to tamper with it for the purpose of gaining access to the house through the open window.
#A further object of the invention is to provide a screen of the character described which/allows ofla certain degree of draft regulationby imparting -adesiredf direction to the outside air entering through the screen. Y i Further objects and advantages of my invention will appear as the specification proceeds. It Should be noted that in the drawing I show two forms, which may be used singly or in combina-V tion or which may be substituted one for the other, although I prefer to use the two forms, each in its place, one being better adapted to be used in connection with the lower sash of a double sash window and the other being better adapted to be used in connection with the upper sash.
The two forms of my invention are illustrated i in the accompanying drawing, in which Figure 1 shows a front View of a double sash window having my two screens attached thereto, the upper sash being' partly open;
Figure 2 a central vertical section through the window shown in Figure 1,
Figure 3 a front View` of the same window, with the upper sash closed and the lower sash partly open,
Figure 4 a central vertical section through the window shown in Figure 3, and
Figure 5 an enlarged detail View of the lower portionof thesection shown in Figure 4.
While I have shown only the preferred forms of my invention I wish to have it understood that various changes and modifications may be made within the scope of the claims hereto attached without departing from the spirit of the invention.
Referring to the drawing in detail it will be noted that the window I is substantially of stand# ard construction and-includes the frame `2 and the two sashes3 and 4 slidable therein with`freedom of vertical movement in overlappingrela# tion. `Suitable weights (not'shown) may be providedirn a conventional manner for causing the sashes to remain automatically in any position to which they `have been adjusted. l Y i Each ofthe sasheshas its own screenfassoci'- ated therewith, the `lower screen being shown at 5 and the upper screen being shown 4at The lower screen is made somewhat more Substanz@ tial than the upperscreen, becausefthe danger of a'burglar trying to break in through the lower screen `is greater. It is alsoconstructed differ-A ently to allowA of a certain amount of draft regu` lation.
The lower screen comprises a plurality of horizontal plates 'I arranged in edge to edgerelation so as to formacontinuous series of plates vwhich areV hingedltogether Valong the contiguous edges thereof. The lowermo'stof `the plates is hinged toa 'stationary plate 8 secured on `the window sill 9 andthe uppermost is hinged'to a plate `Ill secured to the bottom member II of theblwer sash, a thin strip of Wood I2 being preferably interposed, the strip running between the vertical guides I3 secured to the frame. The hinges are preferably arranged with the hinge pins alternately on different sides of the plates, whereby a slight angularity is maintained even in the most extended position of the screen. It will be noted that in the drawing four diiferent plates are shown, with a central hinge pin I4, which is disposed on the outside of the two plates connected thereby and which rides in vertical slots I5 provided in the window frame so as to be confined to a vertical path. The other two hinge pins I6 are disposed on the inside of each set of plates connected thereby so that even if the three hinge pins were perfectly alined in the most extended position of the screen, the plates would still maintain a slight angularity to one another which `is required for the initial collapsing movement.
The pins I6 cannot swing inwardly beyond the vertical plane of pin I4 because they are prevented from doing so by the upright guides I3 fastened to the sash.
The plates are perforated to allow of the entrance of air therethrough and the perforations are preferably punched into the plates from the inside so as to leave a roughened outer surface with sharp projecting points to make it more diicult to tamper with the screen from the outside. Suitable handles I8 are provided on the lower sash member to allow the sash to be raised conveniently and these handles are preferably provided with spring extensions I9 bearing down on the uppermost plate when the screen is collapsed.
The operation of the lower screen will be readily understood from the foregoing description. As the lower sash is raised the plates which normally lie one on the other as shown in Figure 2, are raised with the sash in zig-zag relation to assume the position indicated in Figure 5, the hinge pin I4 being conned to a vertical path' while the other hinge pins are gradually drawn toward the sash as the assembly straightens out. The plates are prevented from straightening out .com-
pletely into a vertical plane by the peculiar hinge arrangement so that when the sash ls lowered again the plate assembly will automaticallycollapse into the position indicated in Figure 2, the spring I8 aiding in bringing about a perfect collapse.
It will be noted due to the angular relationship of the plates the air passing through it is directed either upwardly or downwardly, whereby direct draft is largely eliminated. The plates directing the draft downward may, of course, be left unperforated, if no downward draft is desired. e The upper screen 6 is in the nature of a conventional shade and comprises a conventional shade roller 2| with the well-known spring mechanism (not shown in the drawing), tending to turn the roller in one direction and a wire screen 22 wound thereon, the lower edge ofthe wire screen being secured to the top member of the upper sash as shown at 23. The screen is preferably made of `a width to cover the entire window opening and should be made of rather elastic material, such as spring steel.
In this manner the raising of the lower sash will automatically set in action, the lower screen while thelowering of the upper sash will set in motion the upper screen, so that the window opening is covered at all times while both screens collapse automatically when the sashes are closed.
I claim:
1. A burglar-proof screen for a window having a frame and a sash slidable therein, comprising a plurality of perforated plates arranged in edge to edge relation to form a continuous assembly, hinge pins connecting the plates and means for connecting the end plates to the frame and the sash respectively whereby the assembly is made to expand and collapse in response to sash movements, the hinge pins being offset relative to the plate assembly and being disposed alternately on opposite sides of the latter to facilitate the collapsing operation.
2. A burglar-proof screen for a window having a frame and a sash slidable therein, comprising a plurality of plates arranged in edge to edge relation to form a continuous assembly, hinge pins connecting the plates, means for connecting the end plates to the frame and the sash respectively whereby the assembly is ,made to expand and collapse in response to sash movements and spring means secured relative to the sash and bearing on the collapsed plate assembly for urging the plates thereof into close relation.
, 3. A burglar-proof screen for a window having a .frame and a sash slidable therein, comprising a plurality of plates arranged in edge to edge relation to form a continuous assembly, hinge pins connecting the plates, means for connecting the end plates to the frame and the sash respectively whereby the assembly is made to expand and collapse in response to sash movements, the hinge pins being oilset relative to the plate assembly and. being disposed alternately on opposite sides of the latter to facilitate the collapsing operation and alternate hinge pins extending beyond the plates and having guide means for retaining the same in a plane adjacent the sash during the collapsing operation, and spring means secured relative to the sash and bearing on the collapsed plate assembly for urging the plates thereof into close relation when collapsed.
