Abstract
Abstract A lock assembly for the door of a cabinet or other enclosure where a lock housing is mounted in the door panel having an opening exposing an actuating face on the housing that is flush with the exterior surface of the door panel. The actuating face includes a pivoted pull and a rotatable lock plug actuating a reciprocable bolt to prevent pivotal movement of the pull. The pull has a depending arm engaging an actuating surface of a pivotally mounted latch bolt spring-biased to latching position. The latch bolt has a radially developed bevel on the strike engaging camming surface normally projecting through a side of the lock housing.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
161 words
A flush mount lock assembly for a door or the like, comprising an elongated housing having a recess therein open to the front face thereof, a pivotally mounted latch bolt located substantially wholly within and having a latching projection, said housing having a sidewall with an opening therein to allow advancement of the latching projection therethrough, means biasing said latch bolt to pivot and advance the latching projection through the sidewall opening in the housing, a pull in and normally covering the recess in the housing, a pivot pin extending transversely to the pivot axis of the latch bolt and across said housing and through said pull to pivotally mount the pull about a transverse axis, a depending projection on said pull having a reaction surface, and a reaction surface on the latch bolt abutting the reaction surface on the pull so that pivotal movement of said pull will cause pivotal movement of said latch bolt to retract said latching projection.
Claim 2
Dependent Claim
161 words
A flush mount lock assembly for a door or the like, comprising an elongated housing having a recess therein open to the front face thereof, a pivotally mounted latch bolt located substantially wholly within and having a latching projection, said housing having a sidewall with an opening therein to allow advancement of the latching projection therethrough, means biasing said latch bolt to pivot and advance the latching projection through the sidewall opening in the housing, a pull in and normally covering the recess in the housing, a pivot pin extending transversely to the pivot axis of the latch bolt and across said housing and through said pull to pivotally mount the pull about a transverse axis, a depending projection on said pull having a reaction surface, and a reaction surface on the latch bolt abutting the reaction surface on the pull so that pivotal movement of said pull will cause pivotal movement of said latch bolt to retract said latching projection.
Claim 3
Dependent Claim
40 words
A flush mount lock assembly as set forth in claim 1, in which said latching projection has a flat latching surface and a radially developed camming surface adapted to cooperate with a striking surface on an enclosure for the door.
Claim 4
Dependent Claim
43 words
A flush mount lock assembly as set forth in claim 1, including a hub formed on the rear surface of said latch bolt to provide a pivotal axis therefor, said housing having an opening in a rear wall to conformably receive said hub.
Claim 5
Dependent Claim
37 words
A flush mount lock assembly as set forth in claim 3, in which said reaction surface on said latch bolt is closely adjacent said hub and generally parallel to the direction of movement of said latching projection.
Claim 6
Dependent Claim
27 words
A flush mount lock assembly as set forth in claim 3, in which said pivot pin is generally horizontally aligned with said hub on the latch bolt.
Claim 7
Dependent Claim
68 words
A flush mount lock assembly as set forth in claim 1, in which said biasing means is a compression spring, a pocket in the sidewall of the housing, generally horizontally aligned with said opening in the opposite sidewall for the latching projection, receiving one end of said spring, and a spring pocket on the latch bolt opposite the latching projection to receive the opposite end of the spring.
Claim 8
Dependent Claim
38 words
A flush mount lock assembly as set forth in claim 1, in which said housing has an opening therethrough below said recess, a lock plug conformably received in said opening, and a lock bolt cooperating with said plug.
Claim 9
Dependent Claim
37 words
A flush mount lock assembly as set forth in claim 7, in which said housing has a channel intersecting said opening for the lock plug and said recess, said lock bolt, being reciprocably mounted in said channel.
Claim 10
Dependent Claim
82 words
A flush mount lock assembly as set forth in claim 8, in which said lock plug includes a face flange, a semicircular hub under said flange, said plug having a semicircular undercut under said flange and cooperating with said semicircular hub to form a pair of opposed shoulders, and a tab extending from one edge of said lock bolt into the undercut on said plug and adapted to cooperate with said shoulders to reciprocate the lock bolt upon rotation of said plug.
Claim 11
Dependent Claim
37 words
A flush mount lock assembly as set forth in claim 9, in which said lock bolt has an arcuate recess on one edge with said tab projecting from said recess adapted to receive said semicircular hub therein.
Claim 12
Dependent Claim
59 words
A flush mount lock assembly as set forth in claim 8, in which said lock bolt has a pair of spaced downwardly bent stops on an edge thereof, and a pair of spaced transversely extending parallel pins in the housing above and below said lock plug and cooperating with said stops on the lock bolt to limit reciprocation thereof.
Claim 13
Dependent Claim
44 words
A flush mount lock assembly as set forth in claim 8, in which said pull has a recess in one corner adapted to receive an end of said lock bolt to prevent depression of the end of the pull having the last mentioned recess.
Claim 14
Dependent Claim
41 words
A flush mount lock assembly as set forth in claim 8, including a depending portion on one corner of said pull having a slot therein adapted to receive an end of said lock bolt to prevent pivotal movement of said pull.
Claim 15
Dependent Claim
