Abstract

PURPOSE:To reversely actuate a door without giving pain to a passenger by elastically supporting a door stop post, pressing this door stop post to actuate a switch, and reversely opening the door. CONSTITUTION:When a passenger 9 is brought into contact with only a door 6 and pressed to a door stop post 11, it is displaced by bending a supporting rubber 13, and the door 6 is inversely opened by actuating a switch 15. Since the door 6 is damped by the supporting rubber 13, the switch 15 is actuated by displacing the door stop post 11 even when the passenger 9 is pressed to the door stop post 11 interposed by the door 6. In this way, the door 6 can be inversely opened without giving pain to the passenger 9.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a safety device for a door installed at an entrance/exit of an elevator.

[Prior Art] FIG. 5 is a cross-sectional view of a main part of a car showing a conventional elevator doorway safety device disclosed in, for example, Japanese Utility Model Publication No. 56-13338.

In the diagram, (1) is the elevator car, (2) the foot and floor,
(3) A wall erected around the basket floor (2), (4) is a door stop pillar, (5) is a door pocket pillar, and (6) is a wall that is driven by an electric motor (not shown). A door consisting of a single sliding door that opens and closes the entrance, (7) is a sill that guides the lower end of the door (6), and (8) is the rear part of the front edge of the door (6) (hoistway side)
It is a contact rod that is attached along the front side of the vehicle, and when touched by a passenger (9), retreats to operate a safety switch (not shown).

The conventional elevator entrance/exit safety device is constructed as described above.The door (6) opens and closes the entrance/exit at the base (1), but when the door (6) is in the closing operation, the passenger (9) When the contact rod (8) is caught in the door, the contact rod (8) retreats, a safety switch is activated, and the door (6) is reversed and opened.

[Problems to be Solved by the Invention] In the conventional elevator entrance/exit safety device as described above, when a passenger (9) is caught in the door (6), the door (6)
The contact rod (8) attached to the back of the front edge of the door (6) moves backward to turn the door (6) upside down, so that the passenger (9) can close the door (6) without hitting the contact rod (8). There is a problem in that when the door (6) touches only the door stop, the door (6) does not turn over and is pressed against the door stop pillar (4), making it feel normal.

This invention was made to solve the above-mentioned problems, and is a safety device for elevator entrances and exits that allows passengers to flip the door without feeling uncomfortable even if they are pressed against the doorstop. The purpose is to provide

[Means for Solving the Problems] The elevator entrance/exit safety device according to the present invention elastically supports a door stop column, and when the door stop column is pressed, a switch is operated to reversely open the door. This is what I did.

[Function] In this invention, the door stop post is elastically supported, and when the door stop post is pressed, a switch is activated to open the door inverted, so that passengers are prevented from getting caught in the door and being pressed against the door stop post. When this happens, the door stop column will be displaced and the switch will operate.

[Embodiment] Figures 1 to 4 are diagrams showing one embodiment of the present invention, in which Figure 1 is a cross-sectional view of the main part of the car, Figure 2 is a rear view of the door stop column, and Figure 3 is a rear view of the door stop column. The figure is a sectional view taken along the line ■--■ in FIG. 2, and FIG. 4 is an explanatory diagram of the operation, and parts similar to those of the conventional device are designated by the same reference numerals.

In the figure, (11) is a door stop post installed along the vertical direction at the end of the wall (3), and (12) is an L-shaped mounting bracket fixed to the back of the door stop post (11). , (13) is a support rubber that connects the end of the wall (3) and the mounting bracket (12), (14) is an L-shaped support fixed to the wall (3), and (15) is the support ( 14), and the actuating part (roller) is in contact with the back surface of the door stop column (11).

In the safety device for the elevator entrance/exit configured as described above, when a passenger (9) contacts only the door (6) and is pressed against the door stop column (11), the support rubber (13) is bent, the door stop column (11) is displaced, and the switch (15) is operated, so that the door (6) is reversely opened. In addition, since it is buffered by the support rubber (13),
The amount given to the passenger (9) is usually small.

In addition, even if the handcart collides with the door stopper pillar (11) when getting on and off, the door stopper post (11) will be displaced, so the door stopper pillar (11) will be displaced.
11) damage can be prevented.

[Effects of the invention] As explained above, in this invention, a column per door is elastically supported, and when this door column is pressed, a switch is activated.
Since the door is designed to open in reverse, if a passenger gets caught in the door and is pressed against the door stop pillar, the door stop pillar will be displaced and the door can be reversed without causing discomfort to the passenger. be.
