WINDOW OPENER Filed Feb. 9, 1954 H/f A fro/@Mfr I United States 4Patent F WINDOW OPENER Henry G. Feitig, Philadelphia, Pa. Application February 9, 1954, Serial No. 4l)9,160

2 Claims. l(Cl. 254-131) This invention relates toa window `openingdevice, and more particularly to a device for use in opening household windows which are jammed or stuck.

It is not an uncommon experience for a householder yto double sash type having wooden -sashes and frames, which sashes must be lifted vertically so as to slide within the window frame.

When jamming or sticking of the window sashes in the manner described above is encountered, it is often extremely ditiicult, if not impossible, to force the window open from the inside, for it is impossible to get a tool of any type underneath the bottommost window sash since said sash is seated with a recess in the window sill. Thus, the householder ordinarily has to go to the outside of the window so that he may insert a suitable tool such as a screwdriver or chisel underneath the sash for forcing it upwardly. This, of course, is an extremely inconvenient means of opening the window, inasmuch as some windows are far above the ground and necessitate the use of a ladder, in addition to the fact that adverse weather condi-` tions add to the inconvenience of unjamming the window from the outside.

With the above conditions in mind, the present invention proposes a window opening device which is simple in construction, and simple to use, which device is designed for opening a jammed window from the inside of the house, with a minimum of effort.

It is an object of this invention, therefore, to provide a window opening device for jammed windows.

It is another object of this invention to provide a window opening device for jammed windows which necessitates a minimum of effort on the part of the user in opening the jammed window.

It is a further object of this invention to provide a window opening device which is simple in construction and` cheap to manufacture.

lt is still another object of this invention to provide a window opening device which is suitable for use with the conventional hook grip for window sashes, or the ilush type lift.

This and other objects and advantages to be gained from the present invention will become apparent by reference to the accompanying drawings describing a preferred embodiment in which similar numerals refer to similar parts throughout the several phases.

Figure 1 is a side elevational view of the window opening device of the present invention.

Figure 2 is a front elevational view of the device shown in Fig. 1.

Figure 3 is a sectional view of the window opening device taken along the line 3--3 of Fig. 2.

AFigure 4 is a side elevational view of the present window opening device, with parts broken away, showing the device in position for opening a jammed window having a conventional hook grip mounted on the window sash.

- Figure 5 isa side elevational view of the present window opening device, with parts broken away, showing the device in position for opening a jammed window having a vflush type lift mounted on the window sash.

Referring to the drawings and particularly Fig. 1, the window opening device of the present invention is therein shown as consisting of a lever 10 of substantially rectangular configuration having a hand grip portion 11 at one end thereof and a pointed nose l12 at the other end thereof opposite from said hand grip 11. Mounted near the pointed nose 12 in hinged fashion is a metallic loop 13 for a purpose to be described below. The said loop ishinged: ly secured thereto by means of a U-shaped fastening member iii, such as fa nail or the like, as-shown in Fig. 3.

Cooperating with the lever member 10 'is a pivot mem ber 15, situated approximately one-quarter of the length of the said lever from the pointed nose 12 thereof. As shown in Figs. 2 and 3, the pivot member 15 is provided with a central slot 16 which extends downwardly from the top thereof to a point near the center thereof. At the bottom of said slot, the pivot member 15 is formed so as to provide a pointed or triangular shaped fulcrum 17. The lever member 10 is received in the slot 16 so as to rest upon the fulcrum 17 and is yieldably secured thereto by a U-shaped fastening member 18. The said U-shaped fastening member 18 slidably resides in a notch 19 provided in the top surface of the lever member 10 with the legs thereof ixedly secured in the pivot member 15, as shown in Figs. 2 and 3.

To use this window opening device for forcing open a jammed window, the pivot member 15 is placed upon the window sill 2o, as shown in Figs. 4 and 5. Fig. 4 illustrates a conventional window sash 21 carrying a window pane 22 and having a hook type lift grip 23 `secured to the inside thereof. To force open a window of this type, the lever member 10 is raised to an angular position so that the pointed nose 12 is pointed downwardly, as shown in Fig. 4, and the metallic loop 13 is inserted on the underside of the hook grip 23 in engagement therewith. Then, a force is exerted on the hand grip end 11 ofthe lever member 10, whereupon said lever pivots about the fulcrum 1'7, with the result that the sash 21 is disengaged from the Awindow sill 20 and the window frame, notl shown, in which the conventional sash resides, by virtue of the mechanical advantage achieved from the lever/fulcrum combination.

ln windows in which the sash 21 is provided with a ush type lift 24 having a recess 25 therein, the window opening device is used as shown in Fig. 5. In this case, the loop member 13 is swung back upon the4 top of the lever member lil and the pointed nose 12 is inserted into the recess 25. Then a force is exerted upon the hand grip end 11 of the lever member 10 and once again the leverage action of the said lever member upon the fulcrum produces a mechanical advantage which facilitates the lifting of the sash 21 from the window sill 20 and window frame.

It will be seen from the above description that an extremely useful device is presented by this application, which is simple in construction and susceptible to economical fabrication. And such device, it will be noted, is simple to use and overcomes some of the difficulties heretofore encountered in attempting to force open jammed windows.

Although the present discussion has been limited to the above described preferred embodiment, variations thereof are possible without departing from the spirit of the invention. It is not intended, therefore, that the invention be limited to the particular embodiment disclosed but only 3 to the inventive concept defined by the appended claims.

What is claimed is:

1. In a window opening device, a lever member of substantially rectangular configuration having a top surface and a bottom surface, one end of said member beingcut back from` a point near the top surface thereof to said bottom surface so as to provide a pointed end, the other end of said lever member being formed with a hand grip, a link pivotally mounted on the top surface of said lever member at the pointed end thereof, the said lever member being provided with a transverse channel in the top surface thereof near said pointed end, a pivot member having a slotted opening therein for supporting said lever member, a fulcrum integrally attached to said pivot member and residing in said slotted opening, and fastening means residing in said transverse channel for holding said lever member in said slotted opening in pivotal engagement with said fulcrum.`

2. In a window opening device, a lever member of substantially `rectangular conguration having a top surface and a bottom surface, one end of said member being cut back from a point near the top surface thereof to said bottom surface so as to provide a pointedV end, the other end 4 of said lever member being formed with a hand grip, a link pivotally mounted on the top surface of said lever member in adjacent relationship to the point thereof and passing beneath the cut back area forming the point, an upstanding pivot member having a slotted opening extending downwardly from the top surface thereof, the bottom of said slotted opening being formed to provide a fulcrum, a transversely extending channel formed in the top surface of said i lever member and dividing the lever member into unequal portions, a U-shaped fastening member having a portion thereof received in said channel for securing the lever member in operative position with respect to said pivot member.
