Description

Elevator doors with retaining features

The present invention relates to a fire door used in an elevator, and more particularly, to prevent toxic fumes from entering another floor or spreading fire through an elevator passage when a fire occurs in a building, The present invention relates to an elevator fire door having a release prevention function for preventing the door from being separated by an impact and opening of the entrance.

In general, the door of the elevator is made of metal to prevent spreading to another floor through the elevator passage when a fire occurs in the building.

That is, the doors installed in the elevator are typically divided into an inner door of the elevator itself and an outer door mounted at the elevator entrance of the building, and they are simultaneously controlled to be opened and closed by an interconnected system.

The inner and outer doors are sliding and are automatically opened and closed by actuators such as motors, and elevator doors composed of a pair of left and right sides are suspended from hangers with rollers for moving rails installed on the upper side. It is opened and closed by an actuator such as a motor.

The outer door that blocks the elevator passage in which the elevator is installed is spaced apart between the sliding door left and right and the entrance inner wall of the elevator passage, thereby preventing the elevator passage and the interior of the building from being completely blocked.

Failure to completely block the elevator corridor and the interior of the building will result in flames or toxic fumes spreading through the elevator corridor to another floor or spreading the fire when a fire breaks out inside the building.

This phenomenon results in a problem that acts as a passage through which the fire spreads through the elevator passage.

 In addition, the door of the elevator is mounted so as to span the upper rail and the lower rail, and if the door is forcibly pushed or impacted at the entrance of the elevator, the door is separated from the elevator passage and the door is opened without an elevator. This will occur.

In this way, the door is opened by an external impact, such as an apartment, when children play with each other in a building where children can use it individually. In addition, safety accidents such as children falling into the open entrance may occur.

The present invention is to solve the above problems, by closing the left and right elevator door and the empty space inevitably generated in the outer periphery of the elevator entrance of the building, when the fire occurs, the fire is spread through the elevator passage, toxic mist An object of the present invention is to provide an elevator fire door that can prevent the flow of water.

It is another object of the present invention to provide an elevator fire prevention door having a departure prevention function that can prevent a safety accident when the door is separated by the impact and the elevator passage is opened when an impact is applied to the door at the entrance of the elevator. It is intended to be.

Elevator fire door of the present invention for solving the above object is provided with a blocking means for blocking the passage and the interior of the building in the upper, lower, left and right of the door. It is to solve this object by allowing them to prevent the door from coming off even when an impact is applied to the door at the entrance side of the elevator.

An elevator door which is opened and closed while a pair of left and right doors installed in the elevator aisle slides to both sides;

In the conventional elevator door consisting of a lower guide frame and an upper guide frame configured to be slidable elevator door,

Contact surface sealing means for blocking the elevator passage by using a step in the pair of door contact surface;

A side sealing means mounted on a side surface of the door to form a side pocket, and a side bent frame formed at a side wall frame fixed to a side wall of an elevator entrance to the side pocket to block an elevator passage;

An upper sealing means coupled to the upper surface portion of the door and having an upper pocket coupled thereto, the upper sealing means integrally bending the upper bending frame on the upper wall plate to be inserted into the upper pocket to block the elevator passage;

It is solved by providing a fire prevention door for an elevator with a departure prevention function, characterized in that it comprises; a lower sealing means having a rail blocking frame to block the elevator passage in combination with the door rail mounted on the bottom of the elevator entrance. I would like to.

The fire door according to the present invention having the above structure completely prevents the fire from spreading through the elevator passage or the harmful gas from entering the room when the fire occurs by completely blocking the passage of the elevator and the interior of the building. To show the effect.

In addition, when an impact is applied at the entrance of the elevator, it is possible to prevent the occurrence of a safety accident in advance as the door is forcibly separated by the elevator passage.

DETAILED DESCRIPTION OF THE INVENTION The present invention showing such an effect will now be described in detail with reference to the accompanying drawings.
