Abstract
Abstract A latch, particularly for vehicle doors, includes a keeper for mounting on a door frame and provided with a recess. A catch for mounting on a door which is associated with a door frame includes a catch pin receivable in the recess and adapted for rotation about its axis. The catch pin includes an abutment face which cooperates with the keeper upon penetration of the catch pin into the recess to thereby prevent opening of the door.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
230 words
A latch, particularly for vehicle doors, comprising a keeper for mounting on a door frame, said keeper being provided with a recess having an inner end and at least one projection extending into said recess and having a lead-in face and an abutment face extending inclined to said lead-in face and facing said inner end of said recess; and a catch for mounting on a door associated with said door frame, said catch including a catch pin rotatable about its axis and being intermediate its ends provided with a cutout so as to form an intermediate pin portion of substantially semicircular cross section having an outer cylindrical face with a central axis eccentrically arranged with respect to said axis of rotation and a contact face transverse to said face, said catch pin being biased about its axis to a first position in which said contact face is arranged to contact said lead-in face in response to movement of said catch into said recess, turning thereby said catch pin to a second position permitting movement of said catch pin past said projection into said recess, said catch pin returning after passing said projection to its first position so that a portion of said cylindrical face of said intermediate portion of said catch pin engages said abutment face of said projection and prevents movement of said catch pin out of said recess.
Claim 2
Dependent Claim
230 words
A latch, particularly for vehicle doors, comprising a keeper for mounting on a door frame, said keeper being provided with a recess having an inner end and at least one projection extending into said recess and having a lead-in face and an abutment face extending inclined to said lead-in face and facing said inner end of said recess; and a catch for mounting on a door associated with said door frame, said catch including a catch pin rotatable about its axis and being intermediate its ends provided with a cutout so as to form an intermediate pin portion of substantially semicircular cross section having an outer cylindrical face with a central axis eccentrically arranged with respect to said axis of rotation and a contact face transverse to said face, said catch pin being biased about its axis to a first position in which said contact face is arranged to contact said lead-in face in response to movement of said catch into said recess, turning thereby said catch pin to a second position permitting movement of said catch pin past said projection into said recess, said catch pin returning after passing said projection to its first position so that a portion of said cylindrical face of said intermediate portion of said catch pin engages said abutment face of said projection and prevents movement of said catch pin out of said recess.
Claim 3
Dependent Claim
25 words
A latch as defined in claim 1, wherein said abutment face of said projection is concentric with said axis of rotation of said latch pin.
Claim 4
Dependent Claim
34 words
A latch as defined in claim 2, wherein said keeper has two such projections arranged spaced from each other in the direction of movement of said catch toward said inner end of said recess.
Claim 5
Dependent Claim
37 words
A latch as defined in claim 1, and including a bearing bushing mounting said catch pin at opposite end portions for rotation, said bushing being provided with a cutout exposing said intermediate portion of said catch pin.
Claim 6
Dependent Claim
19 words
A latch as defined in claim 4, wherein said intermediate portion has a larger diameter than said end portions.
Claim 7
Dependent Claim
23 words
A latch as defined in claim 5, wherein said bushing has an enlarged bore portion housing said intermediate portion of said catch pin.
Claim 8
Dependent Claim
23 words
A latch as defined in claim 6, wherein said enlarged bore portion is concentric with said axis of rotation of said latch pin.
Claim 9
Dependent Claim
48 words
A latch as defined in claim 6, wherein said enlarged bore portion is eccentric with respect to said axis of rotation of said latch pin and substantially coincides with said central axis of said intermediate portion of said catch pin when the latter is in said second position.
Claim 10
Dependent Claim
30 words
A latch as defined in claim 1, said central axis being eccentric relative to said axis of rotation on that side of said catch pin which engages said abutment face.
Claim 11
Dependent Claim
71 words
A latch as defined in claim 4, at least that part of said bearing bushing which mounts one end portion of said catch pin being receivable in said recess of said keeper; and further comprising a strip of metallic material received in said recess and connected with a snap action to said keeper, said strip abutting against said part of said bearing bushing when the same is received in said recess.
Claim 12
Dependent Claim
29 words
A latch as defined in claim 10, said keeper being provided with a pair of slots and said strip having end portions each snapped into one of said slots.
Claim 13
Dependent Claim
14 words
A latch as defined in claim 11, said strip consisting of naturally hardened steel.
Claim 14
Dependent Claim
23 words
A latch as defined in claim 11, said strip having a hard-chrome coated surface aDapted to engage said part of said bearing bushing.
