Abstract
Abstract A driving device employed in a window regulator comprising: a driving member including a shaft and an associating member having at least a notch portion; a drum adjacent to said associating member and having an associating projection capable of associating with said notch portion with some play in the rotational direction; and an elastic member urging said associating member in the rotational direction. The shaking of the crank lever can be surely inhibited.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
214 words
A driving device employed in a window regulator comprising: (a) housing; (b) a driving member including a shaft provided for rotational movement within said housing and an associating member being fixed to said shaft, said associating member extending from said shaft in the radial direction and having at least one notch portion along a peripheral edge of said associating member; (c) a drum being provided within said housing, being adjacent to said associating member, being coaxial with said shaft, being rotatable around said shaft, being axially movable along said shaft and having an associating projection, said associating projection being mounted on a first side surface of said drum facing to said associating member, and being capable of associating said notch portion with some play in the rotational direction; (d) an elastic means for urging said associating member in the rotational direction and for biasing said drum away from said associating member, by engagement of one end of said elastic means with said drum and by engagement of the other end of said elastic means with said associating member; and (e) a brake spring set between an outer peripheral surface of said associating member and an inner peripheral surface of said housing having ends inserted into gaps between said notch portion and said associating projection.
Claim 2
Dependent Claim
214 words
A driving device employed in a window regulator comprising: (a) housing; (b) a driving member including a shaft provided for rotational movement within said housing and an associating member being fixed to said shaft, said associating member extending from said shaft in the radial direction and having at least one notch portion along a peripheral edge of said associating member; (c) a drum being provided within said housing, being adjacent to said associating member, being coaxial with said shaft, being rotatable around said shaft, being axially movable along said shaft and having an associating projection, said associating projection being mounted on a first side surface of said drum facing to said associating member, and being capable of associating said notch portion with some play in the rotational direction; (d) an elastic means for urging said associating member in the rotational direction and for biasing said drum away from said associating member, by engagement of one end of said elastic means with said drum and by engagement of the other end of said elastic means with said associating member; and (e) a brake spring set between an outer peripheral surface of said associating member and an inner peripheral surface of said housing having ends inserted into gaps between said notch portion and said associating projection.
Claim 3
Dependent Claim
15 words
The driving device of claim 1, wherein said elastic means is a torsional coil spring.
Claim 4
Dependent Claim
185 words
The driving device of claim 1, wherein said drum has first ratchet teeth on a second side surface of said drum opposite to said first side surface and wherein said driving device further comprises (f) a ratchet member provided within said housing, adjacent to said drum, coaxial with said shaft, rotatable around said shaft, and having second ratchet teeth on a first side surface of said ratchet member facing to said drum, said second ratchet teeth being capable of being meshed with said first ratchet teeth, (g) a spiral spring located between said housing and said ratchet member and urging said ratchet member in the direction of idling movement of said first ratchet teeth and said second ratchet teeth, (h) a first wire having an end engaged with said drum and a second wire having an end engaged with said ratchet member, and (i) a first pushing projection and a second pushing projection being mounted on both low sides of said associating projection, and being capable of being inserted between bottom surfaces of said associating member and said first side surface of said drum, respectively.
Claim 5
Dependent Claim
30 words
The driving device of claim 3, wherein said elastic means urges said drum and said associating member in the direction of idle movement of said first and second ratchet teeth.
Claim 6
Dependent Claim
14 words
The driving device of claim 3, wherein said ratchet member is a ratchet plate.
Claim 7
Dependent Claim
25 words
The driving device of claim 3, where said ratchet member is a ratchet drum capable of winding said second wire on a peripheral surface thereof.
