Abstract
In a double-deck elevator, a car apparatus includes: a main frame; an upper car and a lower car that are disposed inside the main frame so as to be able to move vertically; and a car suspending body that suspends the upper car and the lower car on the main frame so as to counterbalance each other. A stopper sheave is disposed on a lower portion of the main frame. A flexible stopper cord-like body is wound onto the stopper sheave. The stopper cord-like body is connected to the upper car on a first side of the stopper sheave and is connected to the lower car on a second side of the stopper sheave.
Claims2
A double-deck elevator comprising:
- a car apparatus including:
- a main frame;
- an upper car that is disposed inside the main frame so as to be able to move vertically;
- a lower car that is disposed inside the main frame below the upper car so as to be able to move vertically;
- and
- a car suspending body that suspends the upper car and the lower car on the main frame so as to counterbalance each other,
- the car apparatus being raised and lowered inside a hoistway,
- wherein:
- the car apparatus further includes:
- a stopper sheave that is disposed on a lower portion of the main frame below the lower car;
- and
- a flexible stopper cord-like body that is wound onto the stopper sheave;
- the stopper cord-like body is connected to the upper car on a first side of the stopper sheave, and is connected to the lower car on a second side of the stopper sheave;
- the stopper cord-like body is connected to the upper car or the lower car by means of a clamping apparatus that holds the stopper cord-like body;
- the clamping apparatus includes
- a mounting member that is fixed to the upper car or the lower car;
- a pair of clamping members that are disposed on the mounting member;
- and
- a locking bolt that fastens the clamping members;
- and
- the clamping force by the locking bolt can be adjusted so as to allow the stopper cord-like body to slide relative to the clamping members if the ascent energy of the upper car and the lower car relative to the main frame is excessive.

A double-deck elevator comprising:
- a car apparatus including:
- a main frame;
- an upper car that is disposed inside the main frame so as to be able to move vertically;
- a lower car that is disposed inside the main frame below the upper car so as to be able to move vertically in a vertical direction, the upper car being higher in the vertical direction than the lower car;
- and
- a car suspending body that suspends the upper car and the lower car on the main frame so as to counterbalance each other,
- the car apparatus being raised and lowered inside a hoistway,
- wherein:
- the car apparatus further includes:

- wherein:
- the terminal connecting apparatus further includes:
- a mounting member;
- a screw-threaded rod that passes through the mounting member;
- a nut that is screwed onto an upper end portion of the screw-threaded rod;
- an elastic body that is disposed between the mounting member and the nut and that absorbs stretching of the car suspending body and the stopper cord-like body;
- and
- a collar that is disposed on the mounting member and that surround the screw-threaded rod;
- and
- the stopper cord-like body is connected to a lower end portion of the screw-threaded rod, the lower end portion of the screw-threaded rod being lower in the vertical direction than the upper end portion of the screw-threaded rod.
