2 Claims.
This invention relates to improvements in adjustable screen door guards.
Heretofore, adjustable screen door guards have been provided consisting of a plurality of cross members pivotally connected together and providing a lattice adapted to be positioned in the frame of a screen door adjacent the screen therein. These screen door guards are adjustable as to width by reason of the pivotal connections between the members forming the lattice andconsequently maybe adjusted to fit the frame of any screen door. The ends of the members forming the lattice are frequently curled into scrolls having apertures therein through which screws or other fasteners may be driven into the stiles and bottom rail of the screen door frame to mount the guard in place.
An objection to the conventional screen door guard as above described resides in the fact that the upper ends of members of the lattice that are intermediate the upper corners of the lattice are unbraced. These members are frequently arranged at approximately the center of the screen and approximately waist high. Consequently these ends which are unbraced are most conveniently located to be pushed in pushing the door open. As these ends are unsecured to the door frame and are unbraced frequent pushing thereon tends to weaken the guard and to loosen it from the door frame.
An object of the present invention is to provide an improved adjustable screen door guard which is so constructed as to adequately brace the upper ends of the members forming the lattice which upper ends are located intermediate the upper corners of the lattice so that even though these ends are severely pushed they will not tend to weaken the guard or tend to loosen the guard from the door frame.
More specifically, an object of the invention is to provide an improved adjustable screen door guard consisting of pivotally connected diagonally arranged members forming a lattice and wherein the upper ends of those members which form the upper corners of the lattice are bent horizontally inward and to provide a push bar which slidably receives these ends so as to permit of the adjustment of the guard and which embraces the upper ends of those members that are located intermediate the corners so as to brace and steady them.
With the foregoing and other objects in view, which will be made manifest in the following detailed description and specifically pointed out in the appended claims, reference is had to the 2 accompanying drawings for an illustrative embodiment of the invention, wherein:
Figure 1 is a view in .front elevation of the improved adjustable :screen door guard.
Fig. 2 is a vertical section taken substantially upon the'line 2-2 upon Fig. 1.
Fig. 3 is a vertical section taken substantially upon the line 3-3 upon Fig. .1.
Referring to the accompanying drawings wherein similar reference characters designate similar parts throughout, the improved screen door guard comprises a plurality of diagonally arranged crossed members some of which such as those illustrated at [0 and l I may be regarded as main members in that they extend from corner to corner of the guard. Other members such as those indicated at [2 may be regarded as intermediate members in that their ends are arranged intermediate the corners of the guard. These members are preferably formed of heavy metal strips arranged edgewise to the plane of the guard and have twisted portions indicated at I3 where they cross to facilitate their being riveted together such as by rivets l4. Any other means for pivotally connecting the members of the lattice where they cross each other may be employed if so desired. The ends of the members are preferably curled to provide scrolls such as those indicated at IS on the main members and IE on the intermediate members. These curled or scrolled portions have perforations therein adapted to receive screws or similar fasteners indicated at I! that are adapted to be driven into the stiles and bottom rail of the door frame. As the members of the lattice are pivotally connected together the lattice may be adjusted as to width to accommodate itself to any size of screen door.
In accordance with the present invention the upper ends of the main members [0 and II instead of being scrolled have their ends bent horizontally inward as indicated at I8 and I9 and a push bar generally indicated at 20 is provided. This push bar is in the form of an inverted channel the ends of which are closed by bending the downwardly extending sides 2| inwardly towards each other as indicated at 22 to enclose the horizontal portions l8 and I9. This provides a sliding engagement between the push bar 2|! and the corners of the lattice that does not interfere with the adjustment of the guard. Although the angular relationship between the main members I!) and I l and the horizontal portions l8 and 19 may vary slightly on adjustment of the guard this is taken care of by the upper ends of the main members and II merely flexing slightly to maintain the portions [8 and I9 horizontal within the push bar. The sides 2| of the push bar intermediate its ends extend downwardly and embrace the sides of the scrolled portions 23 on the intermediate members l2 at the top of the lattice. As these scrolled portion are unsecured to the push bar or to the portions I8 and [9 they may merely slide with respect thereto on adjusting the guard to any particular door frame.
As the upper ends of the main members l0 and H are rigidly secured to the stiles of the door frame such as by the screws I1 and the push bar encloses the horizontal portions 18 and IS the push bar is sturdily mounted between the stiles and serves to brace and support the scrolled portions 23. This consequently braces and strengthens the entire lattice at its top where it is unsecured to the door frame. Consequently even though the push bar or the portions 23 are severely pushed in opening the door it will not cause the guard or lattice to warp or rack and to become loosened within the door frame,
From the above-described construction it will be appreciated that the improved guard is materially stronger at the points where the conventional screen door guard is weak and at the same time the structure is such that it does not interfere with the adjustment of the guard to fit various sizes of door-frames.
Various changes may be made in the details of formed of ivotally connected members, the up per ends of members which provide the upper corners of the lattice being bent horizontally inward, and a push bar encircling the inwardly bent portions and slidable relatively thereto, said push bar having downwardly extending sides embracing the upper ends of the lattice forming members that are disposed intermediate the upper corners thereof.
