Abstract
Abstract A retractable door handle, especially suited for vending machines to prevent forcing of the door while locked, is mounted for movement between a retracted position and an extended operative position. A spring urged latch retains the handle in the retracted position when it is moved into that position. A key operated lock is mounted displaced from the handle and includes a latch-releasing member which can be moved upon insertion of the key to unlatch the handle latch, whereupon the handle is moved by a spring to the extended position to be grasped by an operator.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
150 words
A retractable door handle and lock comprising a mounting member providing a housing having an internal cylindrical opening, a handle having a cylindrical shank, a cylindrical drum member rotatably mounted in said housing and having the handle shank mounted therein for axial movement to permit movement of the handLe between a retracted position and an extended operative position, a latch retaining the handle in its retracted position when the handle is in that position, the latch comprising a radially-extending member mounted in the handle shank and latching the shank to the housing through the said drum member, a lock adapted to be mounted in a position displaced from the handle, and a latch releasing member operatively connected to the lock and movable upon operation of the lock to engage the said radially-extending member for unlatching the said latch and thereby permit movement of the handle member to the extended position.
Claim 2
Dependent Claim
150 words
A retractable door handle and lock comprising a mounting member providing a housing having an internal cylindrical opening, a handle having a cylindrical shank, a cylindrical drum member rotatably mounted in said housing and having the handle shank mounted therein for axial movement to permit movement of the handLe between a retracted position and an extended operative position, a latch retaining the handle in its retracted position when the handle is in that position, the latch comprising a radially-extending member mounted in the handle shank and latching the shank to the housing through the said drum member, a lock adapted to be mounted in a position displaced from the handle, and a latch releasing member operatively connected to the lock and movable upon operation of the lock to engage the said radially-extending member for unlatching the said latch and thereby permit movement of the handle member to the extended position.
Claim 3
Dependent Claim
22 words
A handle as claimed in claim 1, wherein the mounting member also mounts the lock in its position displaced from the handle.
Claim 4
Dependent Claim
30 words
A handle as claimed in claim 1, wherein the latch releasing member comprises an arm mounted by the lock for rotative movement about an axis upon operation of the lock.
Claim 5
Dependent Claim
39 words
A handle as claimed in claim 1, wherein said latch member is spring-urged to engage in a circumferential latch slot in the housing and is moved out of the slot for release of the latch by the latch arm.
Claim 6
Dependent Claim
35 words
A handle as claimed in claim 1, wherein the said latch member is engaged in a longitudinal slot in the drum member and thereby constrains the drum member and the shank for relative axial movement.
