Abstract: A winding reel which can be placed on another similar free winding reel so that they can be stored or carried in a comparatively small space and is convenient to carry or handle. The winding reel includes a hollow core section, and first and second flange sections provided at the opposite ends of the core section. The core section includes four core wire pieces extending in an axial direction thereof. The first flange section includes a first flange wire piece extending radially outwardly from a first end of each of the core wire pieces in a plane perpendicular to the axis and a connection wire piece for connecting outer ends of adjacent ones of the first flange wire pieces. The second flange section includes a second flange wire piece extending radially outwardly from a second end of each of the core wire pieces in a plane perpendicular to the axis and a third flange wire piece extending radially inwardly from the second end of each of the core wire pieces in the plane perpendicular to the axis.

Abstract: An emergency intercommunication system for an elevator has an interphone unit and an intercommunication command switch located in an elevator car. A telephone number input apparatus for inputting the desired telephone number is provided in an elevator hall, in connection with a register apparatus for storing the input telephone number. An intercommunication command detecting section for detecting the actuation of the switch is provided in connection with an emergency call apparatus for automatically dialing the stored telephone number to connect the interphone unit with a telephone having the telephone number when the actuation of the switch is detected by the detecting apparatus. Preferably, an identification number input apparatus is provided in the elevator hall so that the register apparatus stores the telephone number only when it is input together with a predetermined identification number.
