Document Type and Number:
Japanese Patent JP7124845
Kind Code:
B2
Abstract:
To provide a noncontact power supply technique of an elevator for supplying power to a car through a conductor wire by using the magnetic field coupling capable of suppressing the shaking of the conductor wire by a simple structure.SOLUTION: A noncontact power supply system is a system for supplying power to a car in an elevator without contact and includes a conductor wire, a power receiving coil, and a holding tool. The conductor wire generates a magnetic field for supplying power and has a pair of hanging parts hanging downward in a hoistway. The power receiving coil is provided on the car and receives power from the conductor wire by the magnetic field coupling. The holding tool holds the pair of hanging parts to form a predetermined interval therebetween.SELECTED DRAWING: Figure 1
