Abstract
A multi-functional timepiece comprises a base, a wheel train mounted on the base for rotation, a cam member rotationally driven by the wheel train about a rotational center, and a rotary member mounted to undergo angular displacement in opposite directions. A display member is integrally connected to the rotary member for angular displacement therewith to display time or date information. An interconnecting member interconnects the cam member to the rotary member such that rotational motion of the cam member effects angular displacement of the rotary member in the opposite directions.
Claims38
A multi-functional timepiece comprising:
- a driving portion for driving the multi-functional timepiece;
- a control portion for controlling operation of the driving portion;
- a wheel train portion mounted for rotation based on the operation of the driving portion;
- an operating cam having a cam peripheral part and mounted for rotational movement about a rotational center based on the rotation of the wheel train portion, the cam peripheral part having a radius extending from the rotational center to an outer peripheral face of the operating cam which varies continuously between a minimum value and a maximum value along the circumferential direction of the cam peripheral part;
- a hammer mounted for oscillating motion by being brought into contact with the outer peripheral face of the operating cam, the operating cam being rotated based on the rotation of the wheel train portion in a direction of substantially increasing a distance between the rotational center of the operating cam to a point where the outer peripheral face of the operating cam is brought into contact with the hammer;
- a day wheel mounted to undergo angular displacement in opposite directions based on the oscillating motion of the hammer;
- and
- a display member for displaying time or date information based on the angular displacement of the day wheel.
