Abstract: A cable release and latch for a security guard hinged to a window or the like has a spring loaded plunger swedged into an outer frame thereof. An armored cable with a flexible inner cable is connected to the spring loaded plunger and extends to a foot treadle operator and shield which may be mounted on the floor inside the opening. Sufficient length of cable is provided to allow free movement of the guard about its hinges. The security guard may thereby be quickly and easily opened without a key by stepping on the foot treadle operator. If the armored cable is severed, the spring loaded plunger advances further into the keeper which retracts the flexible cable within the armored housing to prevent the manual operation of the latch without further dismantling of the cable.

Abstract: A window guard assembly has features that allow it to be released from the inside to allow occupants to escape in case of fire. The window guard assembly also has features that prevent the locking mechanism from being actuated by an intruder on the outside of the building. The guard assembly has a guard mounted to a window frame for covering a window. The guard is pivotally mounted, and a locking mechanism selectively prevents the pivoting of the guard. A latch member controls the locking mechanism. An enclosure is formed around the latch member to prevent access from the exterior. The enclosure has an opening that faces the interior. A pair of doors are located at the opening, one with a vertical hinge, and the other with a horizontal hinge. Both of these doors require opening to reach the latch member. When opened, the doors form a barrier in cooperation with the window frame that requires the intruder to attempt to reach around the doors in order to reach the latch member.

Also disclosed are specific structural details and preferred embodiments of the releasable fastener.

Abstract: A protective enclosure for building openings such as windows and doorways wherein the protective enclosure comprises a peripheral frame member that circumscribes the openings and pivotally mounts a transparent shielding unit. The unit which may function as a window or door, depending upon the application, is provided with a unique hinge and locking arrangement which facilitates the easy opening and closing of the unit with respect to the opening; yet one which provides security against the unauthorized entry through the opening in that the unit may not be removed from the building opening from the outside of the building when the unit is in a closed position.

Abstract: The heavy iron gratings for a burglar-proof window are pivotally mounted on one side. The other side is provided with a latch type locking mechanism using a plunger having a ramped surface to hold a set of ball bearings in locking engagement with a matching cylinder. A small carbon dioxide container is mounted within the latch and is spring loaded with a detent arranged for actuation from within the home which is being protected. When the detent is released, a spring-loaded plunger punctures the carbon dioxide container, and a ramped latching plunger is moved to release the locking ball bearings, and then the iron grating or barrier is then vigorously swung open by the pneumatic pressure from the punctured container.

Abstract: A locking mechanized enclosure is mounted at the edge of a hinged window grate so that its interior side wall and front wall are inaccessible from the outside and all of its exposed walls are solid. A locking member extends into the enclosure from the window frame in back of vertical blocking member within the enclosure. The blocking member can be raised by depressing a pivoted plate. However, access to the plate is only through a door in the enclosure which can be opened only from inside the grate.

Abstract: A conventional doorway, of the kind capable of opening in one direction only, is adapted to resist forceful entry by a caller, even after initial opening of the door by an occupant, due to the presence of a generally rectangular and at least partially translucent closure member which is secured to either the door or the door frame, is movable towards and away from an operative position in which it engages respectively either the door frame or the door, and includes means allowing it to be releasably secured in said operative position to prevent opening of the door through more than a predetermined angle, the closure member then bridging the gap which would otherwise have appeared between the door and the door frame so that entry through the doorway by the caller is denied until said means securing the closure member has been released by the occupant.

Abstract: Security apparatus for attachment to the interior side of conventional residential window structure and which includes a horizontal bar having a plurality of vertical bars fixedly attached thereto. The vertical bars are slidably received in respective apertures suitably provided in the sill of the window, thus the bars may be slidably moved upwardly to a security position which occludes the window and downwardly to an escape position which unobstructs the window. Lock structure is included to lock the bars in the security position and a lock trip/release device makes provisions for releasing the lock structure which causes the bars to gravitate downwardly to the escape position thus enabling occupants of the building to escape outwardly through the window in the event of fire and the like.

Abstract: A guard grille for a window, door, or the like, has a retainer member which is fixedly attached thereto and which is adapted to releasably engage a latching mechanism which is retained on the wall adjacent to a window frame. The latching mechanism includes an inner latching member which is attached to a slidably mounted rod and an outer retainer collet which in the latched position retains the latching member within the retainer member. A spring is placed between the inner latching member and the retainer member, this spring being compressed when the mechanism is in the latched condition. The mechanism is unlatched by means of a knob located adjacent to the inner wall surrounding the window frame, this knob being attached to the rod connected to the inner latching member. Inward actuation of the knob moves the inner latching member away from the retainer collet against the spring, thereby releasing the latching mechanism, the spring and actuation by the operator driving the grille away from the window.

Abstract: A security lock comprising a tube having inner and outer ends and a passage extending between such ends, and a shaft including first and second shaft sections interconnected for pivotal movement relative to each other. The shaft has inner and outer end portions. The shaft has a first position in which it is received in the passage of the tube with the inner end portion of the shaft projecting beyond the inner end portion of the tube. A latch which includes the inner end portion of the shaft releasably locks the shaft in the first position so that upon release of the latch, the shaft can move toward the outer end of the tube.

Abstract: An external steel grating has seven vertical bars welded at their ends to upper and lower horizontal hollow cross bars, end portions of which cross bars are bent rearwardly and secured to a building so that the grating overlies a window opening and protects it against illegal entry.One end of the grating has a loosely hinged connection with the building and the cross bars are jointed near the opposite end of the grating and locked in assembled relation by a hidden bolt in one of the cross bars. A cable from said bolt extends through the last mentioned cross bar to the interior of said building, which cable, when pulled, withdraws the bolt from its locking position and frees the joints for separation by gravity allowing the major hinged portion of the grating to swing freely outwardly and affording a ready escape from the building through said window.

Abstract: A grille assembly readily mountable with a window frame for securing a window against unauthorized entry. The grille includes a plurality of horizontal members, each of which has longitudinally spaced, vertical openings. A plurality of vertical bars extend into the vertical openings of the horizontal members, and concealed mounting assemblies mount the horizontal members with the window frame.

Abstract: A grill is attached over an opening in a building. The top of the grill, which is connected together by a cross member, is securely attached to the side of the building. The lowermost portion of the grill, which is also connected by a cross member, pivots about the upper or a central cross member. The lower portion of the grill is held over the opening and against the side of the building by a quick release locking mechanism operated from inside the building. Upon release of the quick release locking mechanism, the lower portion of the grill will be allowed to swing outward so that a person may leave the building through the opening in case of an emergency.
