Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
172 words
A coupled electromechanical mechanism easily uncoupled for relative rotation when in an assembly comprising a first member mounted for rotation relative to a second member, comprising a rotor mounted in a stator, said stator being adapted to be nonrotatably secured to said second member and said rotor adapted to receive and rotate with said first member, and lock means forming pat of the electromechanical mechanism carried by said mechanism for resisting said stator from rotating relative to said rotor but permitting rotation when receiving said first member, said stator and rotor being generally cylindrical and each including an end face, the end faces being generally coplanar and perpendicular to the cylinder axis, and said lock means including a detent and a spring clip which has a resiliently deflectable leg adapted to releasably engage the detent and resist said stator rotating relative to said rotor, said spring clip and detent being received in one of said stator and rotor and associated with the end face on the other of said stator and rotor.
Claim 2
Dependent Claim
172 words
A coupled electromechanical mechanism easily uncoupled for relative rotation when in an assembly comprising a first member mounted for rotation relative to a second member, comprising a rotor mounted in a stator, said stator being adapted to be nonrotatably secured to said second member and said rotor adapted to receive and rotate with said first member, and lock means forming pat of the electromechanical mechanism carried by said mechanism for resisting said stator from rotating relative to said rotor but permitting rotation when receiving said first member, said stator and rotor being generally cylindrical and each including an end face, the end faces being generally coplanar and perpendicular to the cylinder axis, and said lock means including a detent and a spring clip which has a resiliently deflectable leg adapted to releasably engage the detent and resist said stator rotating relative to said rotor, said spring clip and detent being received in one of said stator and rotor and associated with the end face on the other of said stator and rotor.
Claim 3
Dependent Claim
22 words
The mechanism as recited in claim 1 wherein said stator includes said detent and the spring clip is mounted to said rotor.
Claim 4
Dependent Claim
74 words
The mechanism as recited in claim 2 wherein said rotor has an axially extending groove and said spring clip includes a generally flat plate from which said deflectable leg projects, said plate being received in said groove, and said leg having a V-shaped knee and a foot which is normally biased into the detent to resist said rotation, the knee being engageable to deflect the foot out of said detent to permit said rotation.
Claim 5
Dependent Claim
68 words
The mechanism as recited in claim 2 wherein said leg has, in succession, a first, second and third portion, the first portion extending from said plate, said first and second portions forming an engageable knee, and said third portion forming a deflectable end extending into said detent to prevent said rotation, the third portion being deflectable from the detent upon engagement of the knee to permit said rotation.
Claim 6
Dependent Claim
87 words
The mechanism as recited in claim 1 wherein said stator includes a plurality of radially extending ribs which define angularly spaced detents, and said spring clip has a body disposed in a complementary cavity formed in said rotor and a deflectable leg which is adapted to engage one said detent, the leg having a V-shaped knee portion and a foot extending from said knee to fit between a pair of ribs defining one said detent, the knee being engageable to deflect the foot out of said detent.
Claim 7
Dependent Claim
39 words
The mechanism as recited in claim 5 wherein said rotor end face and cavity extend inwardly of said face to position said spring clip and form a shoulder that defines a fulcrum which engages the leg of said clip.
