Title:
INDICATOR
Document Type and Number:
Japanese Patent JP2021083266
Kind Code:
A
Abstract:
To provide an indicator for turning on light-emitting diodes by attaching the indicator to a person's limb, moving a magnet and generating an induction current in a coil.SOLUTION: A first coil 5 wound around an outer periphery of a pipe 6 having a first magnet 3 is installed in a case 10, a wire 13 is connected to the first magnet 3 and an end of the wire 13 is connected to an end of a pendulum 17. A magnetic substance 9 is attached to the case 10, the first magnet 3 is sucked to make the first magnet approach and an indicator 1 having two light-emitting diodes having respectively different polarities is attached to a person's ankle. When the person moves, the case 10 is stopped, the pendulum 17 is moved, the wire 13 is pulled, and inertial force between the first magnet 3 and the pendulum 17 exceeds suction force between the first magnet 3 and the magnetic substance 9, the first magnet 3 passes through the first coil 5 and an induction current is generated to turn on two light-emitting diodes.SELECTED DRAWING: Figure 2
