Abstract
A pendulum device comprises a pendulum rod, a support member for rockably supporting the pendulum rod to permit the pendulum rod to swing freely within a normal swinging angle, and a locking mechanism mounted on the support member for relative movement between first and second positions. The locking mechanism is operative in the first position to lock the pendulum rod from swinging freely and is operative in the second position to enable the pendulum rod to swing freely within the normal swinging angle.

A pendulum device comprising:
- a pendulum rod;
- a support member for rockably supporting the pendulum rod to permit the pendulum rod to swing freely within a normal swinging angle;
- and locking means mounted on the support member for relative movement between first and second positions, the locking means being operative in the first position to lock the pendulum rod from swinging freely and being operative in the second position to enable the pendulum rod to swing freely within the normal swinging angle.
A pendulum device comprising:
- a pendulum rod having a longitudinal axis;
- a support member;
- means mounting the pendulum rod on the support member for swinging motion about a swinging axis disposed perpendicular to the longitudinal axis and within a desired swinging angle;
- and locking means mounted on the support member for relative movement between first and second positions, the locking means being operative in the first position to lock the pendulum rod from swinging motion and being operative in the second position to enable the pendulum rod to swing freely within the desired swinging angle.
