Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an elevator entrance/exit device.

When the elevator touches down at the corner, a gap is formed between the landing entrance and the car entrance.

Then, the car door and the landing door are engaged and both are opened and closed together.

Since this securing utilizes the gap between the car and the landing, the gap width is relatively wide, and is generally 40mmf&deg.

Therefore, the front wheels of the wheelchair may fall into the gap, causing a problem that gives a feeling of anxiety to a physically disabled person who is using a wheelchair to get in and out of the car.

The present invention aims to eliminate the above-mentioned drawbacks and provides an elevator entrance/exit device in which the width of the gap between the car and the landing becomes narrower when the door is open.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In the figure, 1 is the landing entrance, 1a is the lower edge of the landing entrance 1 consisting of a sill, and 2 is the landing door device mainly consisting of a door.
2a is the engaging body of this, 3 is the cage, 4 is the cage entrance and exit, 4
a is the lower edge of the car doorway consisting of a sill, 5 is a car door device mainly consisting of a door, 5a is an engagement plate thereof, 6 is an auxiliary sill disposed in a groove-shaped recess at the front end of the lower edge 4a; 7 Height and both sides outside the width of the entrance/exit 4 (These are links that are arranged and form a part of the parallel movement mechanism, and the lower edge 4a and the auxiliary sill 6
Both ends are pivotally connected to recesses provided in the.

Reference numeral 8 is arranged at the pivot joint on the lower edge 4a side of the link 7, and one end is this (this) and the other end is a biasing body consisting of a helical torsion spring held by the link 7, counterclockwise in FIG. Link 7 is energized.

Reference numeral 9 corresponds to an engaging element protruding from the car door device 5, and reference numeral 10 corresponds to the engaging element 9 fixed to the auxiliary sill 6, and is a protrusion that is pressed by the engaging element 9 at a position just before the door device 5 is fully opened. be.

That is, the auxiliary sill 6 is held in the retracted position by the biased link 7 as shown in FIG. 3, and a gap A is formed between the auxiliary sill 6 and the lower edge 1a of the landing entrance 1.

When the car 3 passes through the landing, the engagement body 2a and the engagement plate 5a each move relative to each other in the gap A.

1. When the car 3 lands on the floor, the engaging body 2a and the engaging plate 5a are engaged with each other. The landing door device 2 is then opened to the right in FIG.

Then, the engaging element 9 presses the protrusion 10 at the position immediately before full opening.

As a result, the link 7 rotates clockwise against the biasing body 8, and the auxiliary sill 6 advances toward the lower edge 1a of the hall entrance 1, as shown in FIGS. 1 and 3.

Therefore, the gap A becomes narrower, the wheelchair can be prevented from falling into the gap A, and the feeling of anxiety felt by the physically disabled person due to the wide gap A can be eliminated.

In this embodiment, the width of the gap A can be halved by the auxiliary sill 6.

Further, by applying this embodiment, the auxiliary sill 6 can be attached to the lower edge 4a.
It consists of a plate pivotally attached to the front end of the plate, which can be easily rotated and moved forward.
The same effect as the embodiment shown in the figure can be obtained.

Moreover, it is also possible to narrow the width of the gap A to about 1 mm by arranging the auxiliary sill that is pivoted in this way and moving it forward.

In the embodiments shown in FIGS. 1 to 3, the auxiliary sill 6 is provided in the car 3. It is obvious that this arrangement is easy to implement, and that the same effects as those of the embodiments shown in FIGS. 1 to 3 can be obtained.

As explained above, the present invention provides an auxiliary sill that is attached via a parallel link mechanism that is disposed longitudinally along the lower edge of the car entrance and whose pivot axis is disposed in the vertical direction of force, and that is normally held in the retracted position. is moved forward toward the landing entrance by the displacement of a protrusion that is pressed by the lower end of the door of the car door device at a position just before the door is fully opened during the opening operation.

This makes it possible to narrow the gap between the landing and the cars when the doors are opened, making it safer for people with physical disabilities who use wheelchairs, etc., to eliminate the anxiety they feel when getting on and off the elevator. In addition, since the auxiliary sill is driven by the lower end of the car entrance door during the opening operation, the door is moved from the position immediately before fully opening to the fully open position, so the device has a simple configuration and realizes a highly safe elevator entrance/exit system. be.
