Abstract
Abstract A remote actuator (10) for an automobile power door lock application has a housing (12), a first gear reduction stage in a first tier (A) in the housing, a second gear reduction stage in a second tier (B1 in the housing, a reversible pancake-type electric motor (56) in the second tier (B) in the housing operative to drive a second gear means (40,46) through a first gear means (30,32) with two stages of gear reduction between respective ones of a pair of parked positions, a linear actuator (108) in the housing (12) in a third tier (C) thereof movable in extending and retracting directions between positively defined limits, and a rotary detent clutch (88) between the second gear means (40,46) and the linear actuator (108) operative to move the latter in the one of the extending and retracting directions corresponding to the direction of rotation of the second gear means (40,46) and to release the linear actuator (108) at either of the limits thereby to permit overdrive of the second gear means (40,46) to the corresponding one of the parked positions.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
299 words
A remote actuator comprising: a housing (1 2 ) including a planar base (16) and a side wall (18) perpendicular to said base defining an open side (19) of said housing, said housing (12) having a depth dimension (D) perpendicular to said base (16) substantially less than a length dimension (L) parallel to said base (16), characterised in that the actuator includes first gear means (30,32) in a first tier (A) in said housing (12) adjacent said base (16) defining a first gear reduction stage; second gear means (40,46) in a second tier (B) in said housing (12) adjacent said first tier (A) defining a second gear reduction stage and operatively connected to said first gear,means (30,32) whereby two stages of gear reduction are achieved; reversible electric motor means (56) in said second tier (B) connected to said first gear means (30,32) and operative to drive said second gear means (40,46) in either of two directions, opposite to one another, between a pair of parked positions of said second gear means (40,46) : a linear actuator (108) in a third tier (C) in said housing (12) between said second tier (B) and said open side (19), said actuator (108) being bodily shiftable in either one of an extending direction and a retracting direction parallel to said length dimension (L) between positively defined limits; and clutch means (68,88,102) between said linear actuator (108) and said second gear means (40,46) operative to move said linear actuator (108) in the one of said extending and said retracting directions corresponding to the direction of rotation of said second gear means (40,46) and to release said linear actuator (108) at the corresponding one of said limits thereby to permit overdrive by said second gear means (40,46) to the corresponding one of said parked positions.
Claim 2
Dependent Claim
299 words
A remote actuator comprising: a housing (1 2 ) including a planar base (16) and a side wall (18) perpendicular to said base defining an open side (19) of said housing, said housing (12) having a depth dimension (D) perpendicular to said base (16) substantially less than a length dimension (L) parallel to said base (16), characterised in that the actuator includes first gear means (30,32) in a first tier (A) in said housing (12) adjacent said base (16) defining a first gear reduction stage; second gear means (40,46) in a second tier (B) in said housing (12) adjacent said first tier (A) defining a second gear reduction stage and operatively connected to said first gear,means (30,32) whereby two stages of gear reduction are achieved; reversible electric motor means (56) in said second tier (B) connected to said first gear means (30,32) and operative to drive said second gear means (40,46) in either of two directions, opposite to one another, between a pair of parked positions of said second gear means (40,46) : a linear actuator (108) in a third tier (C) in said housing (12) between said second tier (B) and said open side (19), said actuator (108) being bodily shiftable in either one of an extending direction and a retracting direction parallel to said length dimension (L) between positively defined limits; and clutch means (68,88,102) between said linear actuator (108) and said second gear means (40,46) operative to move said linear actuator (108) in the one of said extending and said retracting directions corresponding to the direction of rotation of said second gear means (40,46) and to release said linear actuator (108) at the corresponding one of said limits thereby to permit overdrive by said second gear means (40,46) to the corresponding one of said parked positions.
Claim 3
Dependent Claim
60 words
A remote actuator according to claim 1, characterised in that said first gear means includes a pinion gear (30) connected to said motor means (56) and an intermediate gear (32), and said second gear means includes a pinion gear (40) rotatable as a unit with said intermediate gear (32) and an output gear (46) connected to said clutch means (68,88,102).
Claim 4
Dependent Claim
87 words
A remote actuator according to claim 2, characterised in that said clutch means includes means on said linear actuator (108) defining a plurality of rack gear teeth (112), a rack pinion (68) rotatably supported in said housing (12) in said third tier (C) and meshing with said rack teeth (112) whereby said rack pinion (68) drives said linear actuator (108) in either of said extending and said retracting directions, and a rotary detent clutch (88) between said rack pinion ( 6 8) and said output gear (46).
Claim 5
Dependent Claim

A remote actuator according to claim 3, characterised in that said reversible electric motor means includes a pancake-type armature core (58) . rotatably supported in said housing in said second tier (B) and surrounded by an annular permanent field magnet (64) likewise disposed in said housing (12) in said second tier (B).
Claim 6
Dependent Claim
205 words
A remote actuator according to claim 3, characterised in that said rack pinion (68) and said output gear (46) are independently rotatable about a common axis (50) of said housing (12) and said rotary detent clutch (88) includes a slidable detent (90) supported on said rack pinion (68) for rotation as a unit therewith and for bodily-shiftable movement relative thereto in a plane perpendicular to said common axis (50) between an extended position and a retracted position, spring means (100) between said rack pinion (68) and said detent (90) biasing the latter toward said extended position, means defining a follower (96) on said detent (90), and means on said output gear (46) defining a rigid arm (102) having a pair of converging faces (104,106), each engageable with said follower (96) in a corresponding one of the directions of rotation of said output gear (46) whereby said rack pinion (68) is rotatable as a unit with said output gear (46), while said converging faces (104,106) are operable to cam said detent (90) to said retracted position when said rack pinion (68) is immobilized, thereby permitting continued rotation of said output gear (46) to the corresponding one of said parked positions of said second gear means (40,46).
