Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator door opening device.

[0002]

2. Description of the Related Art Generally, an elevator hall door or a car door is provided with a guide groove in a sill of a hall or a car floor as disclosed, for example, in Japanese Utility Model Publication No. 51-124753, and a guide piece for guiding the groove. It is structured to be opened and closed by the door drive device via the. However, since the guide groove is open upward, dust and mud carried by passengers enter and hinders the movement of the guide piece, which causes a problem that the door cannot be opened and closed.

As a solution to this problem, for example, SAIKAI Sho 60
As disclosed in Japanese Laid-Open Patent Publication No. 137774, a guide groove is provided in the lower part of a landing or a sill of a car, and a door is opened and closed by a door drive device through a guide piece that guides the guide groove. Devices have been proposed to prevent entry into.

Further, in Japanese Utility Model Laid-Open No. 63-167476, a structure is provided in which a groove is provided in the lower part of the door and a projecting body for guiding the groove is provided at the end of the sill. It is designed to prevent entry.

[0005]

In the former one proposed above, since a groove is provided on the lower surface of the sill, two doors are overlapped with each other, and a single-opening door that opens and closes only in one direction, The mechanism of the guide piece for guiding the inner second door is complicated, and there is a problem in practical use. In the latter case, the protrusion that guides the first door will be provided in the center of the threshold, which will be an obstacle when entering and exiting.
After all, there was a problem in practical application.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator single-opening door device that does not complicate the structure and does not obstruct the entrance and exit.

[0007]

In order to achieve the above-mentioned object, in an elevator single-opening door device in which two lateral doors are overlapped and opened and closed only in one direction, a lower surface of a front end of a sill for guiding the doors is provided. A laterally long groove is formed, and a projecting member is provided at the door open end on the upper surface of the sill. On the other hand, a guide piece that engages with the groove is provided at the lower end of the outer first door of the door, and the inside of the door is provided. A guide groove that engages with the protrusion is provided on the lower surface of the second door.

[0008]

Since the present invention is constructed as described above, when the door is opened, the first door is opened along the groove by the guide die engaging with the groove formed in the sill, In the two-door type, a guide groove provided on the lower surface of the sill at an open end of the sill engages with a protrusion to move along the protrusion. As a result, the door device can be easily put into practical use without complicating its structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a schematic diagram of a door closed state showing an embodiment of an elevator single-opening door device of the present invention, FIG. 2 is a schematic diagram showing a door opened state, and FIG. 3 is a sectional view in the door opened state.

An elevator doorway is provided in the hall 1 on each floor, and the vertical frames 2a, 2b and the sill 3 which constitute the elevator doorway are fastened by bolts (not shown). A horizontally long groove 4 is formed in the lower surface of the front end of the sill 3, and a projecting member 5 is provided at the open end of the door of the sill 3.
Is provided. On the other hand, at the lower end of the first door 6, the threshold 3
The guide piece 7 that engages with the groove 4 is provided, and the lower surface of the second door 8 is provided with the guide groove 9 that engages with the protrusion 5 provided at the door open end of the sill 3.

In this embodiment, when the door is opened, the first
The door 6 is opened along the groove 4 by the guide piece 7 engaging with the groove 4 formed in the sill 3, and the second door 8 has a protrusion provided on the lower surface at the door open end of the sill 3. By providing the guide groove 9 that engages with the body 5, the first door 6 starts to move along the groove 4 and at the same time, starts to move along the protruding body 5. Also, when the door closes,
The first door 6 moves along the groove 4, and the second door 8 moves along the protrusion 5.
Move along.

In this way, according to this embodiment, the dirt and mud carried by passengers do not enter the groove of the sill 3 and the movement of the guide piece 7 is not hindered, and the door can be safely opened and closed. Furthermore, in a single door that opens and closes only in one direction,
The mechanism of the guide piece for guiding the inner second door 8 can be easily put into practical use without complicating it.

[0014]

As described in detail above, according to the present invention, it is possible to provide a single-opening door device that does not complicate the structure of the elevator single-opening door device and does not interfere with the entrance and exit.
