Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an elevator that carries passengers up and down a hoistway provided in a high-rise building. This invention relates to a safety device that closes the gap between a car and an entrance to ensure the safety of passengers getting on and off the car.

[Technical background of the invention]

Modern elevators eliminate the gap between the landing and the entrance/exit of the car, that is, the lining clearance, so that, for example, physically handicapped people can get on and off the wheelchairs, handcarts, etc. smoothly and safely. It is requested.

Conventionally, in elevators for boarding and alighting wheelchairs, handcarts, and the like, users are required to be careful not to fall when the wheelchair or the like passes through the gap between the landing and the entrance/exit of the car.

In particular, when a handcart is moved from a luggage elevator car to a landing, the person handling the goods either lifts the handcart, or stretches a steel plate between the landing and the entrance of the car and straddles this to push the handcart. Cars and other items are now being loaded and unloaded.

[Problems with background technology]

However, the above-mentioned elevators not only have safety problems, but are also troublesome to operate.Moreover, under poor operating conditions by a physically disabled person, safety measures must be taken to prevent the elevator from falling. Improvements in this are highly desired.

[Purpose of invention]

The present invention was developed in view of the above-mentioned circumstances, and includes a movable spanning board under the floor located at the entrance/exit of the car so that it can move forward and backward from the landing area of each floor, thereby connecting the landing area and the car. To provide an elevator which eliminates a gap between an entrance and an entrance and allows even a wheelchair or a handcart to get on and off easily and safely.

[Summary of the idea]

In this invention, a comb-teeth part is formed on the floor surface of the entrance/exit of the car, a pair of guide rails are arranged in parallel on both sides of the back side of this comb-teeth part, and a movable spanning plate is installed in both guide rails. It is provided so as to fit into the toothed portion, and is also provided so as to be slidable in the front and back direction so as to close the gap between the comb toothed portion and the landing when the car is placed on the floor, and is directly or indirectly attached to the movable span plate. A connected actuator is provided to close the above-mentioned gap when landing on the floor of the car so that passengers can get on and off the car safely.

[Example of idea]

Hereinafter, the present invention will be described with reference to an illustrated embodiment.

1 to 3, reference numeral 1 denotes an elevator hoistway in a building, and each floor 2 on which this hoistway 1 is located is provided with a landing 4 formed by a three-sided frame 3. and the above three-sided frame 3
On the inside side, a double-opening door 5 is provided so as to be able to open and close in synchronization with a door 8 of a car 6, which will be described later. In addition, in the hoistway 1,
A car 6 connected to an elevator (launching machine) by a hanging rope (not shown) is provided so as to be able to rise and fall freely, and an entrance 7 of the car 6 has a door 8 that opens both ways. 5 and can be opened and closed together. Furthermore, the above-mentioned car 6
A comb-teeth part 9 is formed on the floor surface 6a of the car, and a gap 10 is formed between the comb-teeth part 9 and the landing area 4, and this gap 10 prevents collisions when the car 6 goes up and down. It is formed by a void of a size that does not fit.

On the other hand, on both sides of the back side of the comb tooth section 9 located at the entrance 7 of the car 6, a pair of guide rails 11 having a channel-shaped cross section are arranged in parallel, as shown in FIG. In both guide rails 11, for example, a movable span plate 12 formed by a movable comb is fitted in the comb tooth portion 9 and is slidable in the front and back direction so as to close the gap 10. It is provided. Further, an actuator 13 made of, for example, an electromagnet or a hydraulic cylinder is attached to the back side of the floor surface 6a of the car 6. An actuating rod 14 connected to is connected via a connecting rod 15.
Moreover, this actuator 13 is connected to the car 6.
The above-mentioned gap 10 is closed by moving a movable span plate 12 by a movable comb back and forth in synchronization with the landing on the landing.

Therefore, when the car 6 lands on the landing 4 of a predetermined floor and the doors 5 and 8 are opened synchronously, the actuator 13 controls the operation of the doors 5 and 8. Since they operate in conjunction with each other, the output shaft 13a of this actuator 13 is connected to the connecting rod 1.
5 and the operating rod 14, the movable spanning plate 12
is guided by both guide rails 11 and moves forward to close the gap 10. In this way, the movable span plate 12 closes the gap 10, so that a wheelchair or handcart at the landing 4 can be safely boarded and alighted from the car 6 by crossing the movable span plate 12. It's summery.

[Effect of idea]

As described above, according to the present invention, the car 6
A comb-teeth part 9 is formed on the floor surface 6a of the entrance/exit of the comb-teeth part 9, a pair of guide rails 11 are arranged in parallel on both sides of the back side of the comb-teeth part 9, and a movable span plate 12 is installed in both guide rails 11. The movable span plate 12 is provided so as to fit into the toothed portion 9 and to be slidable in the front and rear direction so as to close the gap 10 between the comb toothed portion 9 and the landing 4 when the car is placed on the floor. Since the actuator 13 is provided which is connected directly or indirectly,
Even if the car 6 lands on the floor while shaking due to an earthquake, etc., the gap 10 is closed safely and reliably, and not only is it possible to smoothly load and unload baggage such as handcarts, but also the entire device can be placed inside the car 6. Since it can be built into the back of the floor, it can be installed in existing equipment, and since it has a simple configuration, it has excellent effects such as easy maintenance and inspection.
