Abstract

A clock movement includes a middle body frame defining a first and a second partitions, an upper cover secured, at the first partition, to the middle body frame, and a base cover secured, at the second partition, to the middle body frame. Components for the movement are disposed in the first and second partitions enclosed, respectively. This converts a planar type arrangement of the components into a two-floor type arrangement, with the result of a decrease in diameter of the movement constructed.

Claims

1. A clock or alarm clock movement comprising:

a middle body frame having a web, the web dividing the middle body frame into a first and a second partitions;

an upper cover secured, at the first partition, to the middle body frame, the upper cover and the middle body frame together being adapted to support a gear train; and

a base cover secured, at the second partition, to the middle body frame, the base cover and the middle body frame together being adapted to receive a motor and a circuit substrate.

2. The movement as claimed in claim 1, wherein the base cover and the middle body frame together are further adapted to receive a battery.

3. The movement as claimed in claim 1, further comprising:

an alarm-setting ring rotatably mounted on the middle body frame, the alarm-setting ring having an inner-tooth portion restrained by the upper cover from falling off the middle body frame, the inner-tooth portion being adapted to drive an alarm-setting gear; and

an alarm-setting knob supported between the middle body frame and the base cover, the alarm-setting knob being adapted to activate a buzzer.

4. The movement as claimed in claim 3, wherein the alarm-setting knob comprises a stem extending upward to a top of the middle body frame.
