Abstract
This invention relates to an elevator signal transmitting equipment characterized in that a shielding body of a magnetic shielding material envelops a transmitting line laid along a shaft through which a cage travels and a portion of a coupling device extending toward said transmitting line, the transmission and reception of signals being realized through the magnetic coupling between said transmitting line and said coupling device to control the operation of said cage, a path through which a part of said coupling device travels being left not enveloped.

An elevator control signal transmitting equipment characterized in that a shielding body of a magnetic shielding material envelops a transmitting line laid along a shaft through which a cage travels and a portion of a coupling device extending toward said transmitting line, the transmission and reception of signals being realized through the magnetic coupling between said transmitting line and said coupling device to control the operation of said cage, a path through which a part of said coupling device travels being left not enveloped.
An elevator control signal transmitting equipment characterized in that the shielding body of the magnetic shielding material, whose interior surface is covered with the radio wave absorbing material stuck thereto, envelops a transmitting line laid along a shaft through which a cage travels and a portion of a coupling device extending toward said transmitting line, the transmission and reception of signals being realized through the magnetic coupling between said transmitting line and said coupling device to control the operation of said cage, a path through which a part of said coupling device travels being left not enveloped.
An elevator control signal transmitting equipment comprising a cage traveling through a shaft and containing an installed transceiver;
- a transmitting line laid lengthwise along said shaft;
- an antenna device connected to said transceiver installed in said cage and positioned toward said transmitting line for permitting the transmission and reception of signals to and from said transmitting line;
- a shielding body for magnetic shielding placed along said shaft, enveloping said transmitting line and an end portion of said antenna device, said body having a gap formed therein for providing a path for said antenna device, said antenna device following the ascending or descending movement of said cage.
