Description

Elevator door separation prevention device between floors {A DEPARTURE PREVENTION DEVICE FOR ELEVATOR DOOR OF INTERFLOOR}

The present invention relates to a device for preventing separation of an elevator door between floors, and more specifically, to a collision between a floor elevator door of each floor due to a malfunction or operation error of an electric wheelchair or a collision caused by carelessness of a user, etc. It relates to a separation prevention device for inter-floor elevator doors that prevents safety accidents by preventing

In general, the inter-floor elevator door installed on each floor of a high-rise building is a door jamb (JAMB) for installing the elevator door in the elevator installation part (door room) of each floor among the elevator passages and a door hanger fixed to the upper wall of the door jamb. It is supported by the case to form a substantially suspended shape, and a guide shoe is installed on the lower side of the elevator door to be guided along the guide groove provided on the lower side of the door chamber.

When such an elevator door receives an impact such as a collision caused by a malfunction or operation error of an electric wheelchair or a collision caused by a user's carelessness with respect to the interfloor elevator door of each floor, the elevator door is lifted upward and the guide shoe guide groove There is a risk of a safety accident by deviating from the

In an effort to solve these problems, technologies such as Patent Publication No. 10-2004-0004791, Patent Publication No. 10-2008-0098970, Patent Publication No. 10-2008-0089989, and Patent Registration No. 10-0880570 have been disclosed. there is a bar

These conventional techniques were generally intended to prevent the elevator door from being separated from the door hanger in response to an impact on the elevator door or to prevent the elevator door from being opened from the door jamb in response to an impact.

However, according to them, the configuration is complicated, the assembly process is also difficult, and the assembly is performed in the process of installing the elevator door with respect to the doorpost.

In addition, the elevator door is supplied in an assembled state before being installed on the doorpost in the number corresponding to each floor, and is in a relationship consisting of a process of installing it on the doorpost.

Among the matters to be considered here, the elevator door is supplied in a form that is easily installed on the door jamb and already assembled from the outside, and at this time, the elevator door has a storage and transfer process in an overlapping form.

In other words, is supplied and supplied, and the elevator door is newly manufactured and installed with safety devices such as a door hanger plate and a door hanger case installed on the upper side of the common elevator door to prevent the upper side of the elevator door from being separated.

Korean Patent Publication No. 10-2004-0004791 (published on January 16, 2004) Korean Patent Publication No. 10-2008-0098970 (published on November 16, 2008) Korean Patent Publication No. 10-2008-0089989 (published on October 8, 2008) Korean Patent Registration No. 10-0880570 (2009.01.20. Notice)

The present invention was made to solve the problems and meet the needs of the prior art, to prevent the elevator door from being lifted from impact on the elevator door, and to load the elevator door even when the elevator door is loaded in an already assembled state. It is to provide a separation prevention device for inter-floor elevator doors that can prevent damage to the surface of.

In order to achieve the above object, the characteristic configuration of the separation prevention device of the interfloor elevator door according to the present invention is installed in the door chamber, and the door jamb formed with the locking portion 22 so that the lower end has an upper locking action ( 20); In the closed state, the hook 30 is installed on the lower part of the elevator door corresponding to the hanging part 22 of the door jamb 20 and is installed so that it protrudes or does not protrude from the surface corresponding to the door jamb. ; The hook 30 is characterized in that it is caught on the hook 22 to prevent the elevator door from being lifted upward in the process of closing the elevator door.

In addition, when the hook 30 protrudes from the surface of the elevator door corresponding to the door jamb, the angle formed by the protruding portion of the hook 30 is an acute angle spanning corresponding to the hook 22 desirable.

According to the configuration of the present invention described above, the hook installed at the lower end of the elevator door is positioned corresponding to the hanging part formed on the door jamb, so that the elevator door is bent by impact. By playing a role, there is an effect of preventing the departure of the elevator door.

1 is a cross-sectional view showing the relationship between an elevator door and a door jamb according to the prior art.
Figure 2 is a cross-sectional view schematically showing the configuration and assembly state of the separation prevention device of the interfloor elevator door according to an embodiment of the present invention.
