Abstract
Abstract A door lock set incorporating a conventionally operating rotating knob, normally incorporating a key-actuated lock, for allowing limited passage through the door from the knob side thereof. Control of the door lock set from the other side is effected through a mounted camming plunger which can effect a retraction of the latchbolt through a simple push action, having an elongated panic bar attached thereto, or a push or rotating action of the plunger, the plunger in this instance mounting a knob thereon for the control thereof.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
199 words
Lock construction comprising a housing, a latchbolt mounted for selective extension and retraction relative to said housing, a latch retractor mounted within said housing, said retractor including forwardly directed arm means, said arm means including a forward portion affixed to the inner end portion of said latchbolt for a selective movement thereof, and shoulder means extending generally transversely relative to said arm means rearward of said latchbolt, means resiliently biasing said retractor and attached latchbolt forwardly toward the extended position of said latchbolt, and retractor actuating means mounted within said housing transversely of said shoulder means and immediately forward thereof, said actuating means being mounted for longitudinal reciprocation transversely across said shoulder means, said actuating means incorporating a camming surface engageable with said shoulder means for a progressive retraction thereof upon an inward movement of said actuating means relative to said housing and shoulder means, said actuating means including a second portion rotatably mounted independently of said first-mentioned portion, means for rotating said second portion, said second portion including a pair of opposed camming edges forcibly engageable with said shoulder means in a manner so as to effect a movement of said retractor upon rotation of said second portion.
Claim 2
Dependent Claim
199 words
Lock construction comprising a housing, a latchbolt mounted for selective extension and retraction relative to said housing, a latch retractor mounted within said housing, said retractor including forwardly directed arm means, said arm means including a forward portion affixed to the inner end portion of said latchbolt for a selective movement thereof, and shoulder means extending generally transversely relative to said arm means rearward of said latchbolt, means resiliently biasing said retractor and attached latchbolt forwardly toward the extended position of said latchbolt, and retractor actuating means mounted within said housing transversely of said shoulder means and immediately forward thereof, said actuating means being mounted for longitudinal reciprocation transversely across said shoulder means, said actuating means incorporating a camming surface engageable with said shoulder means for a progressive retraction thereof upon an inward movement of said actuating means relative to said housing and shoulder means, said actuating means including a second portion rotatably mounted independently of said first-mentioned portion, means for rotating said second portion, said second portion including a pair of opposed camming edges forcibly engageable with said shoulder means in a manner so as to effect a movement of said retractor upon rotation of said second portion.
Claim 3
Dependent Claim
186 words
A door lock construction comprising a housing, a latchbolt selectively extensible and retractable relative to said housing, retractor means mounted within said housing and operatively engaged with said latchbolt, said retractor means being longitudinally movable within said housing in the direction of movement of said latchbolt for effecting the selective extension and retraction of the latchbolt, and actuating means for said retractor means mounted within said housing and engageable with said retractor means, means mounting at least a portion of said actuating means within said housing for longitudinal movement transversely across the path of movement of said retractor means, camming means on said portion of said actuating means operably engageable with said retractor means upon a longitudinal movement of said portion for a cam-produced movement of said retractor means, means mounting at least a portion of said actuating means for rotational movement generally about its longitudinal axis, and camming means on said last-mentioned portion selectively engageable with said retractor means upon a rotation thereof for effecting a cam-produced movement of said retractor means, said two actuating means portions being independent of each other and independently operable.
Claim 4
Dependent Claim
186 words
A door lock construction comprising a housing, a latchbolt selectively extensible and retractable relative to said housing, retractor means mounted within said housing and operatively engaged with said latchbolt, said retractor means being longitudinally movable within said housing in the direction of movement of said latchbolt for effecting the selective extension and retraction of the latchbolt, and actuating means for said retractor means mounted within said housing and engageable with said retractor means, means mounting at least a portion of said actuating means within said housing for longitudinal movement transversely across the path of movement of said retractor means, camming means on said portion of said actuating means operably engageable with said retractor means upon a longitudinal movement of said portion for a cam-produced movement of said retractor means, means mounting at least a portion of said actuating means for rotational movement generally about its longitudinal axis, and camming means on said last-mentioned portion selectively engageable with said retractor means upon a rotation thereof for effecting a cam-produced movement of said retractor means, said two actuating means portions being independent of each other and independently operable.
Claim 5
Dependent Claim
29 words
The construction of claim 2 including a key-controlled knob engaged with and operatively controlling said last-mentioned portion, and a push bar affixed to and operatively controlling said first-mentioned portion.
Claim 6
Dependent Claim
56 words
The construction of claim 2 wherein said first-mentioned actuating means portion is mounted for rotational movement about its longitudinal axis, the camming means on said first-mentioned portion being operatively engageable with said retractor means upon a rotation of said first-mentioned portion for effecting a movement of said retractor means upon a rotation of said first-mentioned portion.
Claim 7
Dependent Claim
18 words
The construction of claim 4 including knob means engaged with and operatively controlling said two actuating means portions.
Claim 8
Dependent Claim
22 words
