Description

s WINDLEVIN UARD arch l (Unull EN! y SAM /V ENTO n Unite This invention relates to a device of the class cornmonly known as window guards. Such a device includes a main frame adapted to be mounted at a window, a closure hinged to the main frame and movable to or from a closed position, and means carried by the closure and relatively movable into and out of engagement with the main frame for retaining the closure in closed position or for releasing it. While usually referred to as a window guard, a device of this class is adapted for use at any wall opening.

A window guard of the class described ordinarily includes a handle at one side, usually the inner side, for relatively moving the retaining means for retaining the closure in closed position or for releasing it. A lock is usually associated with the retaining means or with the handle to lock the retaining means in retaining engagement with the main frame. It is desirable to provide a second handle accessible at the opposite side, usually the outer side, for moving the retaining means to releasing position in the event of re or other emergency. One object of the invention is to provide an improved construction including a second handle, such as last above described, located at the said opposite side and adapted for moving the retaining means to releasing position.

When a second handle is provided at the said opposite side as above stated and when a lock is provided, it is necessary for the lock to be so constructed or located that it is accessible at each side for manual unlocking. Another object of the invention is to provide a window guard having two oppositely located handles as described and having a lock accessible at each side.

Other objects of the invention are to provide various details of construction and arrangement whereby the foregoing rnore general objects are advantageously obtained.

In the drawing I have shown in detail two embodiments of the invention, but it will be understood that various changes may be made from the constructions shown, and that the drawing is not to be construed as defining or limiting the scope of the invention, the claims forming a part of this specification being relied upon for that purpose.

Of the drawing:

Fig. l is a front view of a window guard embodying the invention.

Fig. 2 is an enlarged front view of a portion of the window guard as shown in Fig. l.

Fig. 3 is a fragmentary horizontal sectional view taken along the line 3--3 of Fig. 2.

Fig. 4 is a fragmentary horizontal sectional view taken along the line 4-4 of Fig. 2.

Fig. 5 is -a fragmentary vertical sectional view taken along the line 5-5 of Fig. 2.

Fig. 6 is a fragmentary front view similar to Fig. l but showing an alternative embodiment of the invention.

Fig. 7 is an enlarged fragmentary vertical sectional view taken along theline 77 of Fig. 6.

Referring to the drawing and more particularly to Figs. 1 to 5 thereof, 10 is a rectangular main'metallic frame 'ice adapted to be secured in place at a window or at another wall opening. As shown, the `frame 10 comprises angle bars suitably connected at the corners by welding or otherwise. Ordinarily the main frame 10 is located within the window opening in the wall and is located at the inner side of the window sashes.

A closure is provided for the area within the main frame 1d, this closure including a second rectangular metallic frame 12 of such size as to iit Within the main frame 10. As shown, the frame 12 comprises channel bars suitably connected at the corners by welding or otherwise. The closure frame 12 is hinged to the main frame 10 at one edge thereof, and as shown it is hinged at the right edge by means of

hinges

14, 14. The closure also includes suitable closure material, such as wire mesh 18 secured at its edges by welding or otherwise to the closure frame 12. An intermediate reinforcing member is preferably secured to the edge members of the closure frame 12 and this may comprise two

opposed channel bars

20, 20 at opposite sides of the mesh 18. The closure has opposite sides and it is so formed or constructed as to prevent manual access therethrough from either side to the other. As stated, the closure material may include wire mesh such as 18, but the openings through the mesh are not of sufficient size to permit manual access therethrough.

Carried by the closure at or near the edge thereof opposite the

hinges

14, 14 is a retaining means which is relatively movable into and out ofl engagement with the main frame 10 for retaining the closure in closed position or for releasing it. Two manually operable handles are carried by the closure and are respectively located at and accessible at the opposite sides thereof. These handles are connected with the retaining means for moving it into and out of retaining engagement with the frame. The retaining means and the operating handles therefor may be widely varied as to details of construction and arrangement. One suitable construction and arrangement is shown in Figs. l to 5 and this will now be described in detail.

Secured to the left edge member of the closure frame 12 is a vertical plate 22. rl`he wire mesh 18 is cut away to provide space for the plate 22 and the edges of the mesh are secured to the said plate as shown in Figs. 3 and 4. A manually operable handle 24 is horizontally pivoted to the plate 22 at 25, the said handle being near the top of the plate and at the front or inner side thereof. The handle 24 is provided at its left end with an extenion 28 which is normally positioned within a vertical slot formed in a plate 30 secured to the left edge member of themain frame 10. The extension 28 constitutes one portion of the before-mentioned retaining means and when entered in the slot in the plate 30 the said extension serves to assist in retaining the closure in closed position. When the handle 24 is moved to the position shown by dotted lines in Fig. 2, the extension 28 is swung upwardly out of the slot so as to at least partly release the closure.

Pivotally connected with the handle 24 at opposite sides of the pivot 26 are

rods

32 and 34 which extend respectively upwardly and downwardly. -The upper end of the rod 32 extends through a small plate 36 carried by the upper member of the closure frame 12 and into an aperture in a similar small plate 37 on the upper member of the main frame 10. Similarly the lower end of the rod 34 extends through a small plate 38 carried by the lower member of the closure frame 12 and into an aperture in a similar small plate 39 on the lower member of the main frame 10. The

rods

32 and 34 cooperate with the handle extension 28 to constitute the said retaining means for the closure. When the parts are in the relative positions shown in Fig. l, the handle extension 28, the upper end of the rod 32, and the lower end of the rod 34 all cooperate to retain the closure in closed position. When the handle is moved to the position shown by dotted lines in Fig. 2, the handle extension 28 is moved out of the slot in the plate 3i) as previously stated and the

rods

32 and 34 are moved respectively downwardly and upwardly so as to withdraw their end portions from engagement with the small plates 37 and 39 on the main frame. Thus the closure is released so that it can be swung on the

hinges

14, 14.

A manually operable handle 40 is horizontally pivote to the `plate 22 at 42, the said handle being substantially spaced downwardly from the handle 24 and being at the opposite or rear side of the said plate 22. A link 44 is provided having its lower end pivotally connected at 46 with the handle 4t), the last said pivotal connection being `at the left of the pivotal connection d2. The upper end portion of the link 44 is bent forwardly and extends through an arcuate slot 48 in the plate 22. The forwardly extending portion of the link 44 is pivotally connected with the handle 24, a common pivotal connection being provided for the upper end of the link i4 and the upper end of the rod 34.

`As has been pointed out, the

handles

24 and 40 are at opposite sides of the closure. The handle 24 is accessible only at the front or inner side and the handle 40 is accessible only at the rear or outer side. The handle 24 is adapted to serve for relatively moving the retaining means as described and the said handle 46 is also adapted for relatively moving the retaining means in the same manner.

The handle 40 is preferably at a considerably lower level than the handle 24. The handle 24 is positioned for convenient operation from the inside of a building and this is the handle which is normally used. In the 'event of a lire or other emergency the handle 40 may be used for operating the retaining means and the position of this handle at a lower level makes it possible for the said handle to be more readily reached from a ladder at the outside of the building.

A manually operable lock is provided which has a single operating means and which normally serves to lock the retaining means in retaining engagement with the main frame and this lock is so constructed and arranged that the operating means thereof is accessible at each side of the closure for manual unlocking so as to release the retaining means for movement by either handle out or its said retaining engagement with the main frame. This lock and the parts associated therewith may be variously constructed and arranged. One suitable construction and arrangement is shown in Figs. l, 2, and 5 and this will be described in detail.

Carried by the closure and preferably by the plate 22 is a relatively movable member, this member being connected for movement with the retaining means and with the handles. Preferably the said member is an integral downward extension 50 on the handle 40, this being located immediately adjacent the plate 22 and at the rear or outer side thereof. The said member or extension is movable in parallelism with the face of the plate. The plate 22 and the extension or member 50 are provided respectively with apertures 52 and 54 which are in register with each other when the retaining means is in its frame engaging position as shown. The plate 22 is .provided with a small opening 56 immediately below the apertures 52 and 54 and of such size as to Vbe adapted to receive the body 58 of a padlock. The shackle 60 of the padlock extends through the apertures 52 and 54 and serves to prevent relative movement of the member 50, thus serving to prevent movement of the retaining means out of its main frame engaging position. The padlock body 53 may have the usual keyway in its lower end for receiving a key, and upon manipulation of the key one leg of the shackle is released in the usual manner. The key and the lock parts associated with the keyway constitute the said single operating means for the lock.

The opening 56 is of suicient depth to permit the padlockbody 5S to move downwardly relatively to the shackle 66 upon unlocking. For a reason hereinafter stated, the apertures S2 and 54 are slots substantially perpendicular to the adjacent edge of the opening 56. The said slots have lengths greater than the major transverse dimension of the padlock shackle 60.

It will be observed that the operating means of the padlock is accessible at each side of the closure. For unlocking, the padlock can be swung toward the front or toward the rear as indicated respectively at 58a and 58b in Fig. 5.

If it be assumed that the padlock is in position 58a at the front and that the shackle 60 is released at the front of the body 58 upon unlocking, the said shackle after release can be pushed rearwardly through the slots 52 and S4 and then moved downwardly and withdrawn forwardly through the opening 56, as indicated at SSC. lf it be assumed that the padlock is in position 58b at the rear and that the shackle 6i) is released at the front of the body 53 upon unlocking, the said` shackle after release can be pushed forwardly through the slots 52 and 54 and then moved upwardly and wtihdrawn rearwardly through the said slots as indicated at 58d in Fig. 5. The described lengths of the slots 52 and 54 make it possible for the padlock to be moved to position 58d.

Figs. 6 and 7 show an alternative embodiment of the invention, wherein the main frame and the closure are or may be substantially as previously described. The main frame is shown at 62 and the closure frame is shown at 64. l'n lieu of the plate 22 a similar but smaller plate 66 is provided. Horizontally movable in at least one guide 70 on the front of the plate 66 is a bar 72. The left portion of the bar '72 extends through an aperture in a small plate 73 on the closure frame 64, the said plate serving as a supplemental guide. The bar 72 normally projects through an aperture in a small plate 74 on the main frame 62. The said bar 72 constitutes means carried by the closure and relatively movable into and out of engagement with the main frame for retaining the closure in closed position or for releasing it.

Carried by the bar 72 at the front thereof is a handle 76 adapted for relatively moving the said bar into and out of engagement with the main frame. A similar handle 78 is carried by the bar 72 at the rear thereof, this last said handle projecting through a horizontal slot 79 in the plate 66. The handle 78 is also adapted for relatively moving the said bar into and out of engagement with the main frame.

Carried by the bar 72 and movable with it is a member 80 corresponding in function with the member 50. The member 80 is adjacent the plate 66 and at the front thereof. The member 80 and the plate 66 are provided respectively with

slots

82 and 84 which are similar to the slots 52 and 54 and which are in register with each other when the retaining means or bar 72 is in its frame engaging position as shown. The plate 66 is provided with an opening 86 similar to the opening 56 and immediately below the

slots

82 and 84, the said opening 86 being of such size as to be adapted to receive a padlock body such as 58. The shackle 60 of the padlock extends through the

slots

82 and 84 and serves to prevent relative movement of the member 80, thus serving to prevent relative movement of the retaining means or bar 72 out of its main frame engaging position.

The padlock as shown in Figs. 6 and 7 functions exactly as previously described and repetition of the description is unnecessary.
