Abstract
Abstract The door of a locker or the like has a portion of its front face recessed to receive a lock mechanism (either permutation, or key operated, or both) with the forward-most portion of the lock mechanism being inwardly of or flush with the front face of the major portion of the locker door. The lock mechanism employs a spring bolt which is retracted and released when the lock is properly operated through its permutation mechanism or the turning of an inserted key. The door is devoid of the usual operating handle and when the spring bolt is released the vertically reciprocating latching bar carried by the inner face of the locker door can be lifted and released for door opening purposes, by using the dialing knob or an inserted key as a handle.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
189 words
In combination, a swinging door for a locker or the like with the face of the door having an opening therethrough adjacent a freeable margin of the door; an actuatable latching bar operatively carried by the door; a frame rigidly set into the door opening and extending rearwardly of the plane of the door and having a portion formed with a bolt receiving slot; movable latching bar controlling means having a portion which forms a shiftable rear of said frame and having another portion extending to and in operative engagement with said latching bar; and a lock mechanism carried by the first-mentioned portion of said latching bar controlling means and having an exposed element confined within said frame but accessible from the front of the frame for manual engagement and operation, said lock mechanism including a reciprocal bolt movable into and out of said bolt receiving slot upon operation of the lock mechanism so that when said bolt is free of said slot, manual force applied to the exposed element of the lock mechanism will transmit movement to the latching bar controlling means to thereby actuate said latching bar.
Claim 2
Dependent Claim
189 words
In combination, a swinging door for a locker or the like with the face of the door having an opening therethrough adjacent a freeable margin of the door; an actuatable latching bar operatively carried by the door; a frame rigidly set into the door opening and extending rearwardly of the plane of the door and having a portion formed with a bolt receiving slot; movable latching bar controlling means having a portion which forms a shiftable rear of said frame and having another portion extending to and in operative engagement with said latching bar; and a lock mechanism carried by the first-mentioned portion of said latching bar controlling means and having an exposed element confined within said frame but accessible from the front of the frame for manual engagement and operation, said lock mechanism including a reciprocal bolt movable into and out of said bolt receiving slot upon operation of the lock mechanism so that when said bolt is free of said slot, manual force applied to the exposed element of the lock mechanism will transmit movement to the latching bar controlling means to thereby actuate said latching bar.
Claim 3
Dependent Claim
55 words
The combination recited in claim 1 wherein the latching bar is mounted for vertical reciprocation, as is the latching bar controlling means, and the lock mechanism bolt reciprocates horizontally and the exposed element of the lock mechanism, when subjected to a lifting force, will raise the latching bar controlling means and the engaged latching bar.
Claim 4
Dependent Claim
33 words
The combination recited in claim 2 wherein, when the lifting force on the exposed element of the lock mechanism is released, the latching bar controlling means will gravitate to its normal lowered position.
Claim 5
Dependent Claim
13 words
The combination recited in claim 1 wherein the reciprocal bolt is spring loaded.
Claim 6
Dependent Claim
35 words
The combination recited in claim 1 wherein the lock mechanism includes a component-containing casing mounted on the rear face of the first-mentioned portion of the latching bar controlling means and is covered and protected thereby.
Claim 7
Dependent Claim
29 words
The combination recited in claim 4 wherein the rigidly mounted frame has affixed thereto a slotted bar relative to which the spring loaded bolt may be projected or retracted.
Claim 8
Dependent Claim
40 words
The combination recited in claim 2 wherein the portion of the latching bar controlling means which extends into operative engagement with the latching bar is ''''T'''' shaped for interchangeable engagement with a latching bar on either margin of the door.
Claim 9
Dependent Claim
177 words
The combination with a swinging door for a locker or the like with the face of the door having an opening therethrough adjacent a freeable Margin of the door with an actuatable latching member operatively carried by the door adjacent the freeable margin of the latter; of a frame rigidly set into said door opening and extending rearwardly of the plane of the door and having a portion formed with a bolt receiving slot; an inset reciprocal plate closing the rear of the frame and having a first, inactive position and a second, operative position; a manually operated lock mechanism including a reciprocal bolt carried by said plate to control locking and release of the latter and plate reciprocations; and motion transmitting means extending between said plate and said latching member and being movable with said reciprocal plate when the lock bolt is free of its frame slot through operation of the lock and movement of said plate from its first position to its second position, the latter being accomplished by manually moving a plate carried element.
Claim 10
Dependent Claim
177 words
The combination with a swinging door for a locker or the like with the face of the door having an opening therethrough adjacent a freeable Margin of the door with an actuatable latching member operatively carried by the door adjacent the freeable margin of the latter; of a frame rigidly set into said door opening and extending rearwardly of the plane of the door and having a portion formed with a bolt receiving slot; an inset reciprocal plate closing the rear of the frame and having a first, inactive position and a second, operative position; a manually operated lock mechanism including a reciprocal bolt carried by said plate to control locking and release of the latter and plate reciprocations; and motion transmitting means extending between said plate and said latching member and being movable with said reciprocal plate when the lock bolt is free of its frame slot through operation of the lock and movement of said plate from its first position to its second position, the latter being accomplished by manually moving a plate carried element.
