Problems solved by technology

However, such adjustments were not possible in previous methods
[0010] In addition, when the front end portion of the plate-shaped sealing member is angled, due to the contact angle, there will be problems such as: line contact cannot be formed, resulting in reduced airtightness; or friction due to surface contact. The force increases, thereby hindering the travel of the door leaf

Embodiment Construction

[0045] Embodiments of the present invention will be described below with reference to the drawings.

[0046] First, the basic overall structure of the door portion of the elevator doorway will be described.

[0047] Such as figure 1 As shown, the entrance and exit device of the elevator consists of a door leaf 1, an upper frame 2 and a vertical frame 3 surrounding the door leaf 1, and a threshold 4 for the door leaf 1 to advance.

[0048] The door leaf 1 is a single-opening door leaf composed of a high-speed door leaf 1a and a low-speed door leaf 1b. Such as figure 1 as well as figure 2 As shown, the high-speed door 1a is located farther from the door pocket 5, and moves faster than the low-speed door 1b when opening and closing.

[0049] When the door leaf 1 is completely closed, the high-speed door leaf 1a, the low-speed door leaf 1b such as figure 2 As shown in (a), it is arranged left and right, and it is in a closed state that blocks the lift opening. In addition, ...

Abstract

A smoke blocking seal member, the replacement time of which can be determined at a glance, which can make flexible and close contact with a mating member such as a door or a frame when the seal member is mounted to the mating member, and which does not hinder the travel of a door. The seal member is used to close a gap between a frame body and a door of an elevator to block smoke. At least that portion of the seal member which makes contact with the frame body is formed by overlaying members with different colors.

Description

technical field [0001] The present invention relates to a smoke shielding sealing member for shielding smoke in the gaps of elevator door leaves and its manufacturing method. Background technique [0002] Since there is a gap between the installation frame of the elevator and the door leaf of the elevator, when a fire occurs, smoke will enter the elevator from the gap. In order to block the gap, a sealing member is installed on the door leaf of the elevator to block the gap. [0003] As such an example, for example, there is a structure in which a smoke-shielding member with a U-shaped cross section is fixed to the upper frame of the elevator, and the fluorine-coated, molybdenum-dioxide-coated The upper sealing member applied is fixed (for example, refer to Patent Document 1). [0004] In addition, as the shape of the sealing member, a substantially wedge shape in which the width gradually narrows toward the end has been proposed (for example, refer to Patent Document 2). ...
