Abstract

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.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 179 words
An improved window guard assembly of the type having a guard for covering a building window, attachment means for pivotally mounting the guard to a window frame to allow opening and closing movement, and locking means for selectively preventing opening movement, the locking means including a manually actuable latch member for controlling the locking means, the improvement comprising: enclosure means for surrounding the latch member to prevent access to the latch member from the exterior of the building, the enclosure means having an opening facing the interior of the building for providing access to the latch member from inside the building; and a plurality of doors hingedly mounted to the enclosure means for covering the opening, the doors being of a size that requires all of the doors to be opened to provide access to the latch member, the doors being positioned in relation to each other so that in the open position, they define a barrier that requires one on the exterior of the building to reach around the doors in an attempt to reach the latch member.
Claim 2
Dependent Claim 179 words
An improved window guard assembly of the type having a guard for covering a building window, attachment means for pivotally mounting the guard to a window frame to allow opening and closing movement, and locking means for selectively preventing opening movement, the locking means including a manually actuable latch member for controlling the locking means, the improvement comprising: enclosure means for surrounding the latch member to prevent access to the latch member from the exterior of the building, the enclosure means having an opening facing the interior of the building for providing access to the latch member from inside the building; and a plurality of doors hingedly mounted to the enclosure means for covering the opening, the doors being of a size that requires all of the doors to be opened to provide access to the latch member, the doors being positioned in relation to each other so that in the open position, they define a barrier that requires one on the exterior of the building to reach around the doors in an attempt to reach the latch member.
Claim 3
Dependent Claim 205 words
An improved releasable window guard assembly of the type having a guard for covering a building window, attachment means for pivotally mounting the guard to a window frame to allow opening and closing movement, and locking means for selectively preventing opening movement, the locking means including a manually actuable latch member for controlling the locking means, the improvement comprising: enclosure means adapted to be located at one corner of the window frame for surrounding the latch member to prevent access to the latch member from the exterior of the building, the enclosure means having an opening facing the interior of the building for providing access to the latch member from inside the building; a first door connected to the enclosure means opening by a horizontally oriented hinge; and a second door connected to the enclosure means opening by a vertically oriented hinge, both doors substantially covering the enclosure means opening so as to require both doors to be opened for access to the latch member, the hinges being located so that the doors combine with the window frame to define a barrier that requires one on the exterior of the building to attempt to reach around the doors in order to contact the latch member.
Claim 4
Dependent Claim 205 words
An improved releasable window guard assembly of the type having a guard for covering a building window, attachment means for pivotally mounting the guard to a window frame to allow opening and closing movement, and locking means for selectively preventing opening movement, the locking means including a manually actuable latch member for controlling the locking means, the improvement comprising: enclosure means adapted to be located at one corner of the window frame for surrounding the latch member to prevent access to the latch member from the exterior of the building, the enclosure means having an opening facing the interior of the building for providing access to the latch member from inside the building; a first door connected to the enclosure means opening by a horizontally oriented hinge; and a second door connected to the enclosure means opening by a vertically oriented hinge, both doors substantially covering the enclosure means opening so as to require both doors to be opened for access to the latch member, the hinges being located so that the doors combine with the window frame to define a barrier that requires one on the exterior of the building to attempt to reach around the doors in order to contact the latch member.
Claim 5
Dependent Claim 24 words
The window guard assembly according to claim 2 wherein the enclosure means comprises a rectangular box mounted to a lower corner of the guard.
Claim 6
Dependent Claim 49 words
The window guard assembly according to claim 3 wherein a partition is mounted between the doors and the latch member inside the box, the partition extending vertically a portion of the height of the box, requiring one to reach past the partition in order to contact the latch member.
Claim 7
Dependent Claim 29 words
The window guard assembly according to claim 2 wherein the attachment means comprises a plurality of hinges mounted between the grid and the window frame on one vertical side.
Claim 8
Dependent Claim 74 words
The window guard assembly according to claim 5 wherein the locking means comprises: a tab secured to the window frame on the side opposite the hinges, the tab having a hole therethrough; and a rod slidably carried on one side of the guard and adapted to extend through the hole in the tab; the latch member being located in the enclosure means below the rod for selectively preventing vertical sliding movement of the rod.
Claim 9
Dependent Claim 280 words
