Application April 30, 1954, Serial No. 426,778

13 Claims. (Cl. 292-5) This invention relates to improvements in a guard device for a wall opening. Devices of this type, by reason of common use in window openings, have become known as window guards.

A window' guard ordinarily includes a main frame adapted to be mounted at a Window or other wall opening and a guard closure, such as a frame supporting iron bars or heavy wire mesh, which is hinged to the main frame for movement to or from a closed position. It is a common practice to provide manually Operable retaining means carried by the closure for engagement with the main frame to secure the closure in closed position. It is also a conventional practice to provide a lock in association with the retaining means for the purpose of locking the retaining means in engagement with the main frame. It is well known that window guards are commonly used in institutions of confinement. That is, the guards are employed on the windows of hospitals for the insane and other institutions wherein it is desirable to confine the patients and prevent manual access from one side of the window openings to the other side thereof. In such installations, the closure is generally locked in closed position and the lock is accessible from the inner side of the closure where a handle is generally provided for releasing the retaining means.

In my co-pending application Serial No. 276,128, tiled March 12, 1952, now Patent No. 2,711,565 dated June 28, 1955, I disclosed improvements in a window guard of the aforedescribed type which improvements comprise the addition of a handle on the outer side of the closure and the incorporation of lock structure which is accessible at both the inner and outer sides of the closure. In the said application, I explained that it is highly desirable to provide. the handle and lock structure accessible at the outer side so that a guard closure can be opened in tinesl of emergency by a person outside the building or institution.

In accordance with the present invention, I have incorporated additional improvements in the operating mechanism for the retaining means and in the lock structure therefor, and it is one object of the invention to provide substantially fool-proof and damage-proof locking and operating mechanism for the closure retaining means, which locking and operating mechanism is operable from both sides of the closure.

A more specic object of the invention is to provide in a window guard of the aforedescribed ing handle. and lock structure therefor which are accessible at the outer side of the closure and which can be operated to disengage the closure retaining means despite the interference of a panic stricken or incompetent person attempting to disengage or otherwise manipulate the closure retaining means on the inside thereof.

Other objects of the invention relate to details of construction and arrangement and will become apparent type an operatv members to form corner connections.

the accompanying drawings.

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

Of the drawings,

Fig. 1 is an elevational view of a window guard enibodying the invention and taken from the inner side thereof;

Fig. 2 is an enlarged elevational view of a portion of the window guard taken from the outer side thereof and showing the elements of the mechanism for operating the closure retaining means in the position they assume when the said retaining means is engaged;

Fig. 3 is a View similar to Fig. 2 but showing the said operating mechanism in a second position;

Fig. 4 is a view similar to Figs. 2 and 3 but showing the elements of the operating mechanism in the position they assume when the closure retaining means is released;

Fig. 5 is an enlarged fragmentary vertical sectional view taken along the line 5 5 of Fig. 2;

Fig. 6 is an enlarged fragmentary front view similar to Fig. 1 but showing an alternative embodiment of the invention; and

Fig. 7 is an enlarged fragmentary vertical sectional view taken along the line 7 7 of Fig. 6.

Referring to the drawings, and more particularly to the embodiment shown in Figs. 1 to 5 thereof, the reference numeral 10 designates a main metal frame which is substantially rectangular and which is adapted to be mounted at a window or other wall opening. The rectangular main frame 10 may comprise angle bars which are welded or otherwise suitably connected at the corners, and the frame is ordinarily located at the window opening in the wall on the inner side of the window' sashes.

A closure indicated generally at 12 is hinged to the v main frame 10 for movement to or from a closed position which is shown in Fig. l. The closure 12 includes a second rectangular frame comprising elongated

side frame members

14, 14 and

end frame members

16, 16 which are welded or otherwise secured to the side frame It is preferred that the said side and end frame members comprise channel bars which are so arranged that their open sides face outwardly and their back or rear walls face each other. Closure material such as heavy wire mesh 18 can conveniently be secured to the back walls of the

side channel bars

14, 14 and the

end channel bars

16, 16. An intermediate reenforcing member is preferably secured to the

side channel bars

14, 14 and this may comprise two opposed channel bars 2t), 20 which extend across the wire mesh 18 on the inner side or face thereof and on the outer side or face thereof, respectively.

As shown in the drawings, the closure 12 is adapted to tit within the angle bars making up the main frame 10 when in closed position. Said closure is also adapted to swing inwardly of the window opening on hinges 22, 22-

. shown in Fig. l and which generally faces into the building upon which the Window guard i is mounted. I As previously mentioned, itis conventional practice to provide retaining means which is carried by the closure and which is engageable with the main frame for the purpose of securing the closure in closed position. Thedetails of construction and arrangement of the retaining means may be widely varied. One suitable construction and arrangement is shown in Fig. l wherein the retaining means is located along the left-hand side of the closure 12 and includes a support plate 24 which may also be considered a part of the closure and which is secured as by welding to the left side channel bar 14 and to the wire mesh 18 and also to an intermediate channel-bar 20 of the closure 12. It is preferred that the plate 24 be locatedon the outer side of the wire mesh 18 and that the Vwire mesh extend thereover and be provided with suitable openings for access from the inner side to operating elements which will be described in greater detail hereinafter. While only one plate 24 has been shown, it will be understood that a pair of such plates can be used with one plate mounted on each side of the wire mesh 18.

A manually operable handle 26 is horizontally pivoted to the.plate 24 at 28, the said handle being near the top of the -plate and on the inner side thereof and on the inner side of the wire`mesh 1S. The handle 26 is provided with an extension 30 which is norm-ally positioned within va vertical slot formed in a plate 32 which -is secured tothe left-hand frame member in the main frame 10. The extension 30 "constitutes one portion o'f the retaining means and when inserted in the slot in the plate 3,2 the said extension serves to assist in Aretaining the closure in closed position. When the handle 26 is moved clockwise as viewed lin Fig. 1, the extension 30 is swung upwardly out of the slot so as to at least partly release the closure.

I Pivotally'connected with the handle 26 at opposite radial sides of the pivot 28 are

rods

34 and 36 whichextendupwardlyand downwardly, respectively. The upper end of the rod 34 extends through a small plate 38 carried by the top end frame member 16 of the closure 12 and into an aperture in a similar plate 40 which is secured to the top angle bar member of the main frame 10, Similarly, the lower end of the rod 36 extends through a small plate 42 carried by the bottom end frame member 16 ofthe closure 12 and into an aperture in a similar plate 44 secured to the bottom angle bar of the main frame 10. The

rods

34 and 36 cooperate with the handle extension 30 to constitute the retaining means for the closure 12. When the parts are in the relative position shown in Fig. l, the handle extension 30, the upper end of the rod 34, and the lower end of the rod 36 all cooperate to retainvthe closure V12 in closed position within the main frame 10. When the handle 26 is moved clockwise, the handle extension 30 is moved out of the slot in the plate 32'asrpreviously'stated and the

rods

34 and 36 are moved, respectively, downwardly and upwardly so as to withdraw their -end portions from engagement within the small plates 40'and 44 on the main frame 10. Thus, the closurev1l2 is released so that it can be swung inwardly onthe'hinges 22, 22.

lA second manually operablehandle 46 is horizontally pivoted-to the*` plate -24 at 48, the said handle being substantially spaced downwardly from the handle 26 and mounted onk the opposite or outer side of the plate 24. Alink 50 is provided having its lower end pivotally connected ati-S2 with the handle 46, the last said pivotal connection being at the leftof the pivotal'connection 48. The-upperendportion ofthe link 50 is bent forwardly and extends 'through 'an arcuate slot S4 in the plate 24 and'the forwardly or inwardly extending end portion of theV link -50r'ispivotally connected with thefhandle 26, a commonipivotal connection being provided for the upper end ofl the-linkSt) 'and the upper end of the rod 36.

As has 'been` pointed out, the handles 26`and 46 are at` oppositefsides of they closure 12, the handle 26 being accessiblel only from "the inner side of the closure and the handle 46x-being accessible only from the outer side ofithe closure. Both handles are adapted to cause the previouslydescribed relative movement of the retaining meanstofeect'release'thereof and movement Vof one handle causes-'companion movement of the other of said handles. The handles 26 and 46 are shown in Fig. l in their engaged positions which correspond -to engaged position of the retaining means. The inner handle 26 is normally the handle used, but in the event of iire or other emergency, the outer handle 46 may be operated from outside the building to release the retaining means and open the closure.

The guard device of the present invention is generally similar to prior guard devices which include a main frame, a hinged closure, retaining means for the closure, and a manually operable handle connected with the retaining means. In my before-mentioned patent I disclosed flocking structure associated with an operating handle on the outer side `of the closure for the purpose of locking the handle and thus locking the retaining means in engaged position to retain the closure in closed position. In the said locking structure I provide for a padlock having a shackle which engages the outer handle and the closure.

In accordance with the present invention, I provide an additional locking member which is movably supported on the closure and connected to the outer side operating handle and which is adapted for 'engagement by a padlock to retain the outer handle, and thus the retaining means, 'in engaged position. To incorporate the aforesaid locking member requires modication of the closure and outer handle shown in my said patent and the inclusion of the locking member brings about a different coaction between the closure, the locking structure, the operating handles, and the retaining means.

` One specific but important advantage of the locking member is that it is constructed and arranged to prevent binding of the padlock shackle when force is applied to the inner operating handle.

My novel construction and arrangement of the outer operating handle and the locking structure therefore are best shown in Figs. 2 to 5. In Fig. 2 the outer operating handle'46 is shown in engaged position, the position it assumes when the retaining means are engaged with the main frame 210 to secure the closure 12 in closed position. As shown in said Fig. 2, the operating handle 46 extends substantially horizontally and engages a stop 56 secured to the `plate 24. The said handle has an extension or arm 5S which projects substantially vertically downwardly from the pivot 48 and which is provided with a pin 60 adjacent its lower end which pin projects forwardly or inwardly towards the plate 24. In this connection it will-'be' noted with reference to Fig. 5 that the operating handle 46 is supported on the pivot 48 in outwardly spaced relationship to the plate 24. The said pivot -48 may comprise a bolt having a cylindrical shank and a reduced diameter Vthreaded end which'reeeives a nut 49" for securing the handle 46. Thebolt is preferably secured to the plate, as by welding, and projects to the outer'side thereof. A sleeve 62 is preferably welded to the handle 46 and rotatably embraces the shank of the pivot bolt 48.

The inner end portion of the pin 60 in the vertical arm 5S of the operating handle 46 is received within a slot 64 provided in one arm-66 of a pivotally movable locking member 68 which is mounted on the outer side of the plate `24-and which serves in one pivoted position to lock the handle 46 in engaged position and which serves in another pivoted position to release the handle 46 for movement. The atoredescribed pin 'and slot connection between the handle 46 and locking member 68 provides support guide means for the locking member and is positioned tovresist the major portion of any pressure brought on-the locking m-ember by attempted movement of the said handle when the said locking member is in its said locking'position. The said inner end of the pin 60 is provided with a head 61 which prevents removal of the said 'pin 60 through the slot 64 and thereby provides means to prevent bending the arm 58out-wardly relative to the movable lockingmember 68 so as to disengage the pin and slot connection. f

The said locking member 68 is in the form of a crank which has two

arms

70 and 72 in addition to the arm 66. The

arms

66 and 70 are preferably integrally formed from an elongated sheet metal strip which has one end portion bent upon itself as shown in Fig. 5. The bent end portion forms the arm 66 of two wall thickness with the slot 64 being provided in the outer wall thereof. The other or unbent end portion of the sheet metal strip comprises the arm 70 and a longitudinal slot 74 is provided therein for a purpose which will be described.

The locking member 68 is secured between the

arms

66 and 70 to a pin 76 which projects through a suitable opening in the plate 24 and is rotatable within a bushing 78 which is welded or otherwise secured to the inner face of said plate. A knob 80 is secured to the inner end of the pin 76 so that rotation of the knob 80 on the inner side of the plate 24 will pivot the member 68 on the outer side of the plate 24. The third arm 72 of the member 68 is secured to the

arms

66 and 70 adjacent the pivot pin 76 and extends generally radially upwardly and at an angle with respect to the

arms

66 and 70. The said third arm 72 is provided at its free end with a knob or handle 82 which may be gripped by a person on the outer side of the closure 12 and plate 24 to pivot the member 68. Thus the locking member 68 can be moved from the inside by the knob 80 and from the outside by the knob or handle 82.

It is important to observe that in the normal or engaged position of the operating handle 46 and the locking member 68 as shown in Figs. 2 and 5, the pin 60 on the handle 46 is located adjacent the radially inner end of the slot 64 in the arm 66 which is disposed substantially vertically. It should also be noted that the said pin 60 is substantially coaxially aligned with the pivot pin 76. In this relative position of the operating handle 46`and member 68, the arm 70 extends substantially vertically downwardly from the pivot pin 76 and the slot 74 is in register with a similar slot 84 provided in the plate 24. The slot 84 is spaced above a substantially larger opening 86 in the said plate. The opening 86 accommodates the body of a padlock 88 having a shackle which extends through the registering

slots

74 and 84.

Obviously, with the padlock in place as shown in Figs. 2 and 5, the locking member 68 is prevented from movement relative to the plate 24. In the locked position of the member 68 with the arm 66 and slot 64 extending vertically, the operating arm 46 cannot be pivoted because the pin 60 cannot be moved within the slot 64. No matter what amount of force is applied to the inner operating handle 26 in an attempt to disengage the retaining means, such force cannot cause a binding of the padlock shackle within the registering

slots

74 and 84. More specifically, any force applied to the inner operating handle 26 is applied indirectly to the locking member 68 by the pin 60 which is located in coaxial alignment with the pivot of the said member 68. The result is that such force applied to the inner handle 26 cannot be applied on a moment arm tending to cause pivotal movement of the said member 68, it being borne in mind that pivotal movement of the locking member 68 could bind the padlock shackle within the

slots

74 and 84. The padlock 88 must be removed and the locking member 68 must be rotated from the position shown in Figs. 2 and 5 before either of the operating handles 26 and 46 can be pivoted to release the closure retaining means.

Removal of the padlock 88 may be accomplished from either the inner side of the closure or from the outer side thereof because the padlock opening 86 in the plate 24 permits such access. When the padlock 88 has been removed, the locking member 68 can easily be rotated to the position shown in Fig. 3 by manipulation of the operating knob 82 on the outer side of the plate 24 or by manipulation of the knob 80 connected to the pivot pin 76 on the inner side of the plate 24. In fact, the arrangement of the locking member 68, and particularly the crank arm 72' thereof, is such as to permit gravity biased movement of said member 68 from the position shown in Fig. 2 to the position shown in Fig. 3. More specifically, the weight of the crank or lever arm 72 and the knob 82 provided at the end thereof is not counterbalanced and, since said crank arm and knob extend upwardly and toward the right as viewed in Figs. 2 to 4, it will be seen that the weight thereof will cause clockwise pivotal movement of the member 68 to the position shown in Fig. 3. The amount or degree of clockwise pivotal movement of the member 68 is limited to the position shown in Fig. 3 by means of a stop 90 which engages the arm 70 when the same is disposed substantially horizontally. In such position of the locking member 68, the pin 60 carried by the arm 58 on the operating handle 46 can be moved Within the slot 64 in the arm 66. Thereupon by means of either the handle 26 or the handle 46, the parts may be moved to the positions shown in Fig. 4 so as to release the closure retaining means.

Although the locking member is intended to be automatically movable by gravity to its inoperative position when released by the lock, nal dependence is not placed upon automatic movement. A window guard embodying the present invention may be installed in an institution of confinement and then not used for a long time, perhaps not for may years. But it must always be ready for use. Due to the gumming of oil or the accumulation of dust or for some other reason, the parts may be too sluggish to move by gravity as intended. In such event they can be moved by the manual means 80, 82 that is provided and the device remains fully operative.

The operation of the operating and locking mechanism associated with the closure retaining means will be apparent from the foregoing description and, therefore, only a brief summary of such operation is believed to be necessary.

If the closure 12 is to be opened from the inner side thereof, it is only necessary to unlock the padlock 88 and disengage its shackle from the registering

slots

74 and 84 and to manipulate the knob 80 to be sure that the locking member 68 is pivoted to the position shown in Fig. 3 before moving the inner operating handle 26 clockwise to disengage the retaining means in the manner previously described. side thereof, the padlock 88 is disengaged and the operating knob is manipulated to be sure that the locking member 68 assumes the position shown in Fig. 3 before grippingv and moving the outer operating handle 46 counterclockwise as viewed in Figs. 2 to 4 to effect disengagement of the retaining means in the manner previously described.

It is an important aspect of the aforedescribed window guard that the operating elements located on the outer side of the closure are not susceptible to damage nor cantheir operation be impeded by the eiorts of a panic stricken or incompetent person attempting to operate the handle 26 on the inner side of the closure. In addition, the outer operating elements are protected from outside damage. More specifically, stops 92 and 94 are secured to the outer side of the plate 24 to engage the

arms

72 and 70 respectively of the member 68 when the said member isdisposed in normal position. The stops 92 and 94 are similar to the stop and comprise short pieces of angle bar which may be Welded to the plate 24 so that one side or leg of the angle bar stops will extend over the arms of the member 68 and prevent outward bending of the arms of the said member which might cause improper operation thereof.

Figs. 6 and 7 show an alternative embodiment of the invention wherein most of the elements of the window guard are the same as previously described and, therefore, are identified by the same reference numerals. The prin` cipal changes made relate to the location of the inner and outer operating handles. In the alternative embodiment an inner operating handle'96 is provided in substanl If the closure is to be opened from the outery `7 tally identical. fornito the previously described inner operating lhandlelllti andltheihandleg isprovided withan extension98-which isnormally engaged Awithin a'slot provided=in a iplate 100-secured to the left side kof the'main framefl. The outer operating handle 1.02 is'substantially identical tothe previously described outer operating handle 46. Thehandles 96 and 102m the alternative embodiment are mountedxon a common pivot connection 1M- which-comprises a stub shaft having .a threadedend 106 for interconnecting .the

handles

96 and 102 by the use of :anut 108. The said shaft isxedly secured to the handle :96.andrprovided'with a square shankportion 110 received within the operating handle .102 so that the handles-96sand 102i will be pivotedisimultaneously by the application of-force to either.

:fThe outer. handle`102 isprovided with an extension or armi-58 similar toits counterpart on the previously describedouter arm 46Jand said armcarries a pin 69 which isass'ociated with the slot 64 inthe locking member 68.

A .plate 1'12'is provided in place of the previously described plate 24 but is of lesser dimensions, the said plate 112-being secured to the closure 12 as shown in Fig. 6 andsimilar to the manner described in connection with the description of the plate 24. It will be understood that theplat'e 112 can be located in various other positions along the side of the closure 12 as may be determined for convenient access.

Retaining rods 114 and .116 are substituted for the previously described retaining

rods

34 and 36, respectively. 1t will be'seen that the upwardly extending rod 114 is pivotally connected at its lower end. 18 to the inner operating 'handle 96 on one side of the .pivot 104 and theupper end 120 of the downwardly extendingrod 116 is pivotally connected to the inner operating arm 96 on the radially opposite side of the pivot 104.

The manner of operation of the alternative embodiment of the invention is identical with the operation of the first described embodiment and, therefore, a review thereof is deemed unnecessary.
