In the conventional elevator door chamber, the door guide shoe is inserted into the groove, so in a normal door operating environment, the door guide shoe travels along the groove without leaving the door chamber, and the door guide shoe does not leave the door chamber even when the door is closed. . However, if the door is lifted by an external physical force or impacted in the direction of the hoistway while the door is closed, the door or the door guide shoe bends and is released from the door compartment, which causes the door to be pushed in the hoistway direction. Passengers at risk of falling onto the hoistway.

Conventional elevator doors are always exposed to accidents caused by passengers falling due to the doors falling due to carelessness or mischief of passengers, wear of the door shoes due to prolonged use, deformation of the doors, and misalignment of the door shoes. The casualties of accidents should be prevented. The door shoe installed at the lower part of the elevator door is installed to be guided to the fixed door room and has an installation structure in which only the shoe part is inserted from the top to the door room groove. The door shoe has a structure in which the installation structure is inserted downward from the top of the door chamber, so that the door shoe fixed by the connecting bolt to the door is lifted up with the door and detached from the door due to the depression of the door due to external impact. When the shoe of the door shoe is worn, there is a gap with the door seal groove, and the connecting piece and the mounting bracket part are easily bent due to the external shock, thereby causing a problem of being separated from the door chamber. In addition, the separation rate of the door also greatly depends on the amount of shoe buried in the door chamber groove, foreign matters accumulated in the door chamber groove to interfere with the sliding of the shoe in the door chamber to cause the failure of the elevator.

The present invention has been made to improve the above problems, when the door is closed when the protrusion of the bracket protrusion is inserted into the protrusion insertion groove of the bracket groove and the impact of the elevator door in the direction of the elevator door does not push or lift the door The purpose of the present invention is to develop a door compartment structure that prevents the guide shoe from falling out and prevents the elevator door from falling out of the door compartment so that elevator users can use the elevator more safely.

The present invention is the elevator door 10, the door guide shoe 12 is connected to the fixing groove with a connection bolt; And the door 10 of the elevator door 10 in which the door guide shoe 12 of the elevator door 10 has a built-in door chamber 20 in which the briquette nut 60 and the bolt 70 are coupled to each other. It is mounted on the lower side of the side, the bracket projection 30 is formed with a protrusion 32 in a direction perpendicular to the side of the door 10; And a protrusion insertion groove 42 formed to allow the protrusion 32 of the bracket protrusion 30 to be inserted, and includes a bracket groove 40 mounted to the door chamber 20, and the door 10 is formed. It relates to an elevator door chamber structure, characterized in that the protrusion 32 of the bracket protrusion 30 is inserted into the protrusion insertion groove 42 of the bracket groove 40 at the moment of closing.

3 and 4, the door door structure of the elevator has an elevator door 10 is connected to the fixing groove of the door guide shoe 12, the door guide of the elevator door 10 to the door chamber 20 Since the shoe 12 is built in and the door guide shoe fixing plate 32 is built in, the door guide shoe 12 and the door guide shoe fixing plate 32 are not separated, and an impact is applied to the shoe guide plate. In the door seal structure of the present invention, when the door 10 is closed, the protrusion 32 of the bracket protrusion 30 is inserted into the protrusion insertion groove 42 of the bracket groove 40 to impact the elevator door in the lifting direction. In this case, it is possible to prevent the door guide shoe 12 from being pulled out without the door 10 being pushed or lifted and to prevent the elevator door 10 from being detached from the door chamber 20.

3 to 5, in the door seal structure of the present invention, the bracket protrusion 30 is mounted to the outside of the lower side of the door 10 and the bracket nut 60 and the bolt (mounted to the inside of the door 10) 70) is mounted in a coupled state. As shown in FIGS. 1 and 2, the bracket protrusion 30 has a protrusion 32 formed in a direction perpendicular to the side surface of the door 10 such that the protrusion insertion groove 42 of the bracket groove 40 is formed at the moment when the door 10 is closed. When the protrusion 32 of the bracket protrusion 30 is inserted into the elevator door to impact the door of the elevator, the elevator door 10 may be prevented from being separated from the door chamber 20. 1 and 2, the bracket groove 40 has a protrusion insertion groove 42 formed therein so that the protrusion 32 of the bracket protrusion 30 can be inserted and the bracket groove 40 at the moment the door 10 is closed. When the protrusion 32 of the bracket protrusion 30 is inserted into the protrusion insertion groove 42 of the protrusion to impact the door of the elevator, the elevator door 10 may be prevented from being separated from the door chamber 20.

As described above, the present invention has been described with reference to the embodiment illustrated in the drawings, but this is only an example, and those skilled in the art may make various forms of deformation and other equivalent embodiments therefrom. Will understand. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.

As described above, the door seal structure of the present invention has a door in which the door is not pushed or lifted up when the door is closed and the protrusion of the bracket protrusion is inserted into the protrusion insertion groove of the bracket groove to impact the elevator door in the lifting direction. The guide shoe can be prevented from falling out and the elevator door can be prevented from being detached from the door room, so that the elevator user can use the elevator more safely.
