Abstract
Abstract A battery operated watch includes an actuator mechanism adapted to actuating indicator hands of the watch. The actuating mechanism includes a gear train adapted to drive indicator hands, a motor for driving the gear train, and an electronic block unit. The electronic block unit includes an oscillator and electronic circuit for operating the motor. A mechanism plate and bridge are provided. A carrier plate of insulative material is disposed between the mechanism plate and bridge. The carrier plate has pockets, including indentations, bores and openings, for receiving and retaining in position at least some components of the actuating mechanism. Means is provided for securing the mechanism plate, bridge, and carrier plate together, including a plurality of pillars extending between the mechanism plate and the bridge.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
188 words
A battery operated watch comprising a one-piece base plate; a one-piece bridge; a one-piece carrier plate formed of insulative material disposed between said base plate and said bridge; said base plate and said bridge engaging opposing surfaces of said carrier plate so that the spacing between said base plate and said bridge is determined by the thickness of the carrier plate; actuating means adapted to activate indicator hands of the watch, said actuating means comprising: a motor mounted in a first pocket in said carrier plate, an electronic block unit mounted in a second pocket in said carrier plate and including an oscillator and electronic circuit for operating said motor, a gear train arranged to drive the indicator hands, said gear train being driven by said motor and including a plurality of intermeshing gears mounted on axles, said axles each including first and second ends rotatably mounted in said bridge and base plate, respectively, said axles passing through openings in said carrier plate, and means for securing said base plate, bridge, said carrier plate together including a plurality of pillars extending between said base plate and said bridge.
Claim 2
Dependent Claim
188 words
A battery operated watch comprising a one-piece base plate; a one-piece bridge; a one-piece carrier plate formed of insulative material disposed between said base plate and said bridge; said base plate and said bridge engaging opposing surfaces of said carrier plate so that the spacing between said base plate and said bridge is determined by the thickness of the carrier plate; actuating means adapted to activate indicator hands of the watch, said actuating means comprising: a motor mounted in a first pocket in said carrier plate, an electronic block unit mounted in a second pocket in said carrier plate and including an oscillator and electronic circuit for operating said motor, a gear train arranged to drive the indicator hands, said gear train being driven by said motor and including a plurality of intermeshing gears mounted on axles, said axles each including first and second ends rotatably mounted in said bridge and base plate, respectively, said axles passing through openings in said carrier plate, and means for securing said base plate, bridge, said carrier plate together including a plurality of pillars extending between said base plate and said bridge.
Claim 3
Dependent Claim
82 words
A watch according to claim 1, wherein said gear train includes a rotor connected to said motor and mounted in said first opening in said carrier plate, said rotor being rotatably mounted to said base plate and said bridge; said motor including a motor coil and stator laminations located on opposite sides of said rotor; said first pocket including indentations shaped in conformance with the outer configurations of said motor coil and stator laminations for receiving said motor coil and said laminations.
Claim 4
Dependent Claim
22 words
A watch according to claim 2, including a pair of fasteners securing said motor coil and stator laminations to said base plate.
Claim 5
Dependent Claim
77 words
A watch according to claim 1, including a hand adjusting shaft and a hand adjusting gear mounted for rotation with said shaft, said carrier plate including a bore extending radially within the plane of said carrier plate for receiving said hand adjusting shaft and an indentation for receiving said hand adjusting gear; a date ring being provided, a date ring adjusting gear being mounted on said adjusting shaft and received in an opening in said carrier plate.
Claim 6
Dependent Claim
62 words
A watch according to claim 1, wherein said gear train includes a minutes gear for driving the minutes hand; said carrier plate includes a central bore aligned axially with a central bearing bore in said base plate and with a bearing bore in said bridge; said minutes gear being mounted on a shaft, said shaft being rotatably supported in said bearing bores.
Claim 7
Dependent Claim
56 words
A watch according to claim 1, wherein said carrier plate includes an indentation for receiving a battery; said indentation including a wall to separate said indentation from said base plate, and also including cavities for receiving contact lugs to electrically connect the battery with the electronic block and to hold the battery within the battery indentation.
Claim 8
Dependent Claim
55 words
A watch according to claim 6 wherein said electronic block unit includes a plate, at least two fasteners connecting said plate to said carrier plate, one of said fasteners also securing to said carrier plate the one of said contact lugs which interconnects a negative battery terminal and an inlet terminal of the electronic block.
Claim 9
Dependent Claim
19 words
A watch according to claim 1 wherein said carrier plate comprises a temperature resistant and dimensionally stable plastic material.
Claim 10
Dependent Claim
34 words
A watch according to claim 1, wherein said carrier plate includes a plurality of holding claws integral about the periphery thereof for securing said carrier plate, base plate, and bridge within a watch housing.
Claim 11
Dependent Claim
63 words
A watch according to claim 1, wherein said pillars each comprise a fixing bolt attached to said base plate and received in a bore of said carrier plate and fastener means for securing said fixing bolt to said bridge; and there being further provided a plurality of fixing pins integral with said carrier plate and engageable within corresponding bores in said base plate.
Claim 12
Dependent Claim
23 words
A watch according to claim 10 wherein said fixing bolt is held by an interference fit within its bore of the carrier plate.
