Abstract
Abstract A thumb lock mechanism for mounting on a panel having a bore in which a rotatable bolt driver may be mounted includes a mounting plate having a bearing and fixed over one end of the bore by fasteners entering the bore and usually engaging a similarly mounted, key-operated device overlying the other end of the bore. A driver bar connects the key-operated device, the rotatable bolt driver and the hub of a rotor plate disposed in the mounting plate bearing. A turn piece peripherally engages the rotor plate and is formed with an extending turn and pull grip having a usually closed port overlying the fasteners. A yielding, axial retainer between the hub and the mounting plate urges detent on the mounting plate and rotor plate into engagement. A hold-back is optionally provided.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
88 words
A thumb turn lock mechanism for mounting on a panel having a bore in which a rotatable bolt driver may be disposed comprising a mounting plate having a central bearing therein, means for holding said mounting plate against said panel over said bore, a rotor plate, a hub on said rotor plate extending through said central bearing, means for limiting axial motion of said hub in said bearing, a turn piece, and means for engaging the periphery of said turn piece with the periphery of said rotor plate.
Claim 2
Dependent Claim
88 words
A thumb turn lock mechanism for mounting on a panel having a bore in which a rotatable bolt driver may be disposed comprising a mounting plate having a central bearing therein, means for holding said mounting plate against said panel over said bore, a rotor plate, a hub on said rotor plate extending through said central bearing, means for limiting axial motion of said hub in said bearing, a turn piece, and means for engaging the periphery of said turn piece with the periphery of said rotor plate.
Claim 3
Dependent Claim
88 words
A thumb turn lock mechanism for mounting on a panel having a bore in which a rotatable bolt driver may be disposed comprising a mounting plate having a central bearing therein, means for holding said mounting plate against said panel over said bore, a rotor plate, a hub on said rotor plate extending through said central bearing, means for limiting axial motion of said hub in said bearing, a turn piece, and means for engaging the periphery of said turn piece with the periphery of said rotor plate.
Claim 4
Dependent Claim
88 words
A thumb turn lock mechanism for mounting on a panel having a bore in which a rotatable bolt driver may be disposed comprising a mounting plate having a central bearing therein, means for holding said mounting plate against said panel over said bore, a rotor plate, a hub on said rotor plate extending through said central bearing, means for limiting axial motion of said hub in said bearing, a turn piece, and means for engaging the periphery of said turn piece with the periphery of said rotor plate.
Claim 5
Dependent Claim
19 words
A device as in claim 1 including grip means outstanding from and extending substantially diametrically of said turn piece.
Claim 6
Dependent Claim
18 words
A device as in claim 2 in which said grip means includes a window overlying said holding means.
Claim 7
Dependent Claim
13 words
A device as in claim 3 including removable means for blocking said window.
Claim 8
Dependent Claim
24 words
A device as in claim 1 including means in said hub for non-rotatably and slidably engaging a driver bar also engaging said bolt driver.
Claim 9
Dependent Claim
20 words
A device as in claim 1 in which said mounting plate and saId rotor plate include interengageable rotary positioning means.
Claim 10
Dependent Claim
23 words
A device as in claim 1 in which said axial motion limiting means includes a spring urging said rotary positioning means into engagement.
Claim 11
Dependent Claim
30 words
A device as in claim 1 in which said axial motion limiting means includes a retainer engaging said hub on the side of said mounting plate opposite said rotor plate.
Claim 12
Dependent Claim
33 words
A device as in claim 1 including a ring interposed between said mounting plate and said rotor plate, and means controlled by said ring for interengaging said mounting plate and said rotor plate.
Claim 13
Dependent Claim
16 words
A device as in claim 9 in which said ring is shiftable transversely of said bore.
Claim 14
Dependent Claim
16 words
A device as in claim 9 including means on said ring slidably engaging said rotor plate.
