Embodiment Construction

[0023] Embodiments will be described in detail below with reference to the drawings.

[0024] First, use figure 1 The overall structure of the elevator apparatus will be described. Such as figure 1 As shown, an elevator apparatus 1 includes a car 4 and a counterweight 5 arranged in a hoistway 3 . A machine room 6 is provided above the hoistway 3, and a traction machine 7 for driving the main rope 9, a control device 8, and the like are provided in the machine room 6. As shown in FIG. The control device 8 is a device that controls the entire elevator apparatus 1, controls the operation of the hoisting machine 7 in response to a hall call or a car call, and makes the car 4 stop at the floor where the call is made.

[0025] In addition, a so-called machine room-less elevator apparatus may be used in which the machine room 6 is not provided, and the hoisting machine 7 and the control device 8 are miniaturized and installed in the upper portion of the hoistway 3 .

Abstract

An elevator apparatus having a closing structure for a gap formed between sills on the hall side and on the car side. By using a link mechanism mechanically linked to the opening and closing of the doors to close the gap between the sills on the hall side and the car side, reliable operation by mechanical drive is realized at low cost. A closing member (35) closing the gap between the car-side threshold (31) and the hall-side threshold is configured to be slidable between a blocking position and a retracted position, and is driven by a link mechanism (41). The blocking part is connected to the action spring that bears the moving force toward the blockage position, and as the car door (25) starts to open, the engagement of the link mechanism and the action part (72) is released to allow the blockage caused by the action spring. The sliding movement of the position is accompanied by the movement of the car door towards the door-closing end, and the link mechanism engages with the action part on the side of the car door, so that the blocking part overcomes the action spring and slides to the retracted position.

Description

technical field [0001] Embodiments of the present invention relate to an elevator apparatus having a blocking structure for a gap formed between sills provided on the hall side and the car side of an entrance / exit portion of a car. Background technique [0002] In an elevator system in which a car installed in a hoistway of a building moves up and down between floors to transport people or goods, a certain gap is provided between the hall of each floor and the car in order to move the car up and down. Therefore, when the car stops at the lobby and the door of the entrance is opened, a gap is generated between the threshold on the lobby side and the threshold on the car side. The gap between the sills is dangerous because a person falls or a wheel of a wheelchair or a trolley gets caught and gets caught. And sometimes small items such as keys or cards fall into the bottom pit from the threshold gap, which is difficult to recycle. [0003] Therefore, conventionally, there ha...
