Abstract

PURPOSE:To prevent an accident due to unexected opening of a cage door by fixing a stopping plate projected to an elevator passage and arranged between mutual elevator stops so as to face to the door pocket side of the stopper of a cage door. CONSTITUTION:A pillar-like stopping plate 5 is fixed at its leg part 5a on the circumferential wall of an elevator passage 1, arranged between mutual elevator stops (2), and provided on the position facing to the door pocket 3d side of the stopper 3c of a cage door 3b. Consequently, when a passenger in a cage forces the door 3b open at abnormal stop of the cage 3, the stopper 3c abuts with the stopping plate 5 to prevent unexpected opening of the cage door 3b. Hereby, an accident due to unexpected opening of the cage door 3b can be prevented.

Description

[Detailed Description of the Invention] [Industrial Application Field] The invention of B relates to an elevator device that prevents a car door from being opened inadvertently.

[Conventional technology]

Figure 4 shows a conventional elevator system shown in, for example, Japanese Utility Model Publication No. 62-11891. A separate landing (3) is a car that goes up and down the hoistway (1), and an entrance (3 m) and a car door (3b) are provided opposite the second landing (2). (4) is the hoistway (1
) is a fasher plate supported on the peripheral wall of the entrance (
3 &) and is arranged so as to close the recess formed between the landings (2).

A conventional elevator system is constructed as described above, and in normal times, the car (3) is stopped facing the landing (2).

The car door (3b) and the landing (2) door are opened and closed. Also.

The car (3) may abnormally stop between the landings (2) during an abnormal power outage, and in this case, the door (3b) of the car may be forced open by a passenger inside the car (3).

In such a case, the fascia plate (4) is installed close to the doorway (3m) to prevent the doorway (3m) from opening accidentally.
This is to prevent passengers from falling into the recess in the peripheral wall of the hoistway (1) from a).

[Problem to be solved by the invention]

In the conventional elevator system as described above, it is necessary to operate the facial plate (4) according to the different widths of the entrance/exit (3a) and the depth of the recess in the circumferential wall of the hoistway (1).

In addition, the Fetusha plate (3 colors) corresponding to the width of the entrance and exit (3 colors)
4) There was a problem in that the device itself was large and required complicated manufacturing, Wl transport, and installation.

The present invention has been made to solve these problems, and an object of the present invention is to provide an elevator device that has a simple configuration and prevents the car from being opened accidentally.

[Means to solve the problem]

In the elevator system according to this invention.

A blocking plate protruding from the hoistway and disposed between the landings is fixed so as to face the door bag side of the engaging piece of the fully closed car door.

[For production]

When the car of the elevator system configured as described above is located in a position that does not face the landing, when the car door attempts to be opened accidentally, the retaining piece of the car door hits the blocking plate, causing the door to open unexpectedly. be prevented.

〔Example〕

1 and 2 are diagrams showing an embodiment of the present invention, and in FIG. 2, the same reference numerals as in FIG. 4 indicate corresponding parts.

(3C) An engagement piece consisting of a member of a well-known engagement mechanism with the door of the landing (2) protruding from the opposite surface of the landing area (2) of the elevator car door (3b); (3d) is the elevator car (3); ), the door pocket of the car door (3b), (5) is a column-shaped blocking plate, and the two leg parts (5a) are fixed to the peripheral wall of the hoistway (1), and are arranged between the two landings (2). It is.

Moreover, it is provided at a position facing the door pocket (3d) side of the retaining piece (3C).

In the elevator system configured as described above, the first
As shown in the figure, when the car (3) has stopped abnormally and the passenger inside the car (3) tries to push open the car door (3b), the engaging piece (3C) engages the blocking plate (5). ), the accidental opening of the car door (3b) is prevented.

Therefore, it is a configuration that can be easily installed using materials that are easy to install, and can be standardized regardless of differences in the width of the entrance/exit (3a). It is possible to prevent accidents from occurring.

FIG. 3 is a diagram showing another embodiment of the present invention.
The same reference numerals as in the figures and FIG. 2 indicate corresponding parts.

(3a) is the rear entrance of the frame (3), (3aa) is the front entrance of the frame (3).

The elevator system configured as described above has a car 13) at the entrance/exit door, but a blocking plate (5
) is provided. Therefore, although a detailed explanation will be omitted, it is clear that the embodiment shown in FIG. 3 provides the same effect as the embodiment shown in FIGS. 1 and 2 regarding the entrances and exits (three colors).

〔Effect of the invention〕

As explained above, when a passenger in the car tries to open the door when the car is in a position not facing the landing, the engagement piece of the car door is inserted into the blocking plate provided in the hoistway. This prevents the door from opening accidentally. This has the effect of preventing accidents caused by unintentional opening of the car door with a device that is simply constructed, inexpensively manufactured, and easily installed.
