Description

TECHNICAL FIELD The present invention relates to an escalator suitable for carrying a wheelchair or the like.

[Background of the Invention]

In the present age, which is aimed at improving the welfare environment, it is desired to adopt specially devised transportation means and building structures so that persons with disabilities who use wheelchairs can act relatively freely.

Recently, with the recognition that the escalator is an indispensable transportation period in the building, it is expected that an escalator that can be easily used by people with physical disabilities and elderly people will be readily available.

However, under the present circumstances, the installation angle and driving speed, which greatly affect the psychology of the escalator user, do not cause any inconvenience to healthy people, but the physically handicapped elderly and physically handicapped people lack the agility to get on and off. For this reason, it has been proposed that the escalator cannot be used and the installation angle for these people is made smaller to increase the sense of stability when riding, or the transport speed is slowed to facilitate getting on and off. There is.
In addition, for those who have difficulty walking and use a wheelchair, there is a demand for an escalator that gives special consideration so that the person can use the wheelchair while riding.

Moreover, at department stores, it was not possible to ride with shopping carts at ease. This is because wheelchairs and carts have wheels and generally do not stably ride on steps with steps.

Conventionally, there are some things that are generally called electric roads and there is no step on the road surface part, but the drawback is that the entire road surface is inclined like a slide and the wheelchair is not stable, and the entire equipment is a long stroke and space efficiency is poor. There was a drawback.

As a means for solving these drawbacks, Japanese Examined Patent Publication No. 56-4155
It is proposed that a specific step is provided in the normal escalator step group like No. 5, the specific step is stopped, and after the wheelchair gets on, it is restarted and carried to the nearest floor. . An example of using a large step is shown as an example of the specific step.

However, when a large step is arranged, there is a problem that a large step is generated between the step and the adjacent step.

As a means of solving this problem, as a specific step, a plan to put an auxiliary plate on a normal step to make it large, or to store the auxiliary plate in the step and pull out the auxiliary plate artificially when necessary, etc. Is proposed.

However, even this one has a drawback that it requires a manual operation and causes a handicapped person or an attendant to perform troublesome work.

[Object of the Invention]

An object of the present invention is to provide an escalator capable of easily, safely, and reliably forming a wheelchair mounting surface without an attendant performing troublesome work.

[Outline of Invention]

The gist of the present invention is to incorporate a drive means for forming a wheelchair mounting surface into a step when transporting a wheelchair, a switch for detecting the formation of the wheelchair mounting surface and stopping the drive means, and a switch near the entrance / exit. The drive means is provided with a power applying means for applying power for forming a wheelchair mounting surface.

S ₁ is a dedicated stop switch for people with disabilities, etc. When using a specific step, this switch S ₁ may be pressed.
K ₂ is a dedicated activation switch that is activated after a wheelchair, etc. gets into a specific step. S _2, S ₃ is in the stop switch provided within the guide track of the step, the specific of the step has summer to issue a command to stop the predetermined Nokuchi and Fukuchi.
30a and 30b are movable contact portions provided on the escalator body 1 side for transmitting and receiving a power source and a signal current,
The movable contact portions 30a and 30b are adapted to move only when the specific step 4 is in this position and engage with the fixed contactor on the step 4 side.

FIG. 2 is a detailed view of the specific step 4. Reference numerals 10 and 11 denote double-arranged tread plates, which are normally arranged on the tread plate 11 so that the tread plates 10 overlap each other as shown by a dotted line in FIG. It is configured to rotate through and reverse as shown by the solid line. 13 is a riser, 14 is a frame body arranged on the left and right, tread plates 10, 11,
It supports the riser 13, the front wheels 8 and the rear wheels 9. 16 is a frame
A motor 17 is provided inside 14, and a gear 17 is attached to an output shaft of the motor 16. Reference numeral 18 denotes a gear that meshes with the gear 17. The gear 18 drives the shaft 19 to rotate,
The link 20 whose one end is fixed is rotated in the direction of arrow a.
One end of a link 21 is fixed to the other end of the link 20, and the other end of the link 21 is rotatably connected to the back surface of the tread plate 10. Reference numeral 22 is a support piece of the link 20, which supports a load applied to the tread plate 10 via the link 21. A switch 23 detects that the tread plate 10 is in the state shown by the dotted line (normal state), and a switch 24 detects that the tread plate 10 is in the state shown by the solid line (state in which the tread is expanded). Is. Reference numeral 25 is a contactor provided at the lower end of the frame body 14, and the contactor 25 is provided with a contact piece 26 for transmitting and receiving a power source and a signal current.
It is adapted to engage with the contact piece 31a of a.

Next, the operation of a specific step will be described.

Now, when the dedicated stop switch S ₁ is pressed, this switch S ₁
In response to a command from, the specific step 4 operates the stop switch S ₂ and stops at the entrance. Next, the movable contact portion 30a moves upward in the direction of arrow C, the contact piece 31a and the contact piece 26 are engaged, and the motor 16 is started. By driving this motor 16, the gear 1
The link 20 is rotated via 7, 18 and the shaft 19, and the tread plate 10 is rotationally moved to the solid line position. Switch 24 at this position
Is activated and the rotation of the motor 16 is stopped. In this way, after the reversing operation of the tread plate 10 is completed, the wheelchair is allowed to board. The rear wheel of the wheelchair is placed on the back side of the tread plate 10 and the front wheel is placed on the tread plate 11.

When the dedicated start-up switch K ₂ is operated after getting on correctly, the contact piece 31a and the contact piece 25 are separated by moving downward in the direction of the movable contact portion 30ad, and the escalator starts the driving operation after a predetermined time. The speed at this time is 10m / min, which is slower than the low speed (30m / min)
Is desirable. When the specific step 4 reaches the vicinity of the upper exit and the stop switch S ₃ is activated, the specific step 4 stops at the exit. When stopped at a predetermined position, the movable contact portion 30b operates and engages with the contactor 25. When the wheelchair descends from the step 4 and a command for normal operation is issued, the motor 16 is started, the tread plate 10 is returned to the position shown by the dotted line, and the motor 16 is stopped by the operation of the switch 23. Then, the movable contact portion 30b is opened, and thereafter, the operation is started to return to the normal operation.

In the above, the case of ascending has been described, but in the case of descending, the tread surface of the specific step 4 may be expanded at the upper entrance and returned to the normal state at the lower exit.

The above is the description of the embodiment of the present invention.According to this embodiment, since the wheelchair can be boarded by forming the wheelchair mounting surface by expanding the tread surface, one step can be used for one wheelchair. Since it can respond and the treads are automatically expanded, wheelchair users and passengers will not be bothered and troubled. Moreover, the switch detects the fact that the wheelchair mounting surface has been formed by the expansion of the tread surface and that the tread plate has returned to its original normal state, and the motor is stopped, so that these operations can be performed reliably. Moreover, since these operations are performed only near the opening / closing port, it is safe.

In this embodiment, the tread plate 10 is rotated to form the wheelchair mounting surface, but the tread plate 10 may be slid backward to form the wheelchair mounting surface.
Further, it can be used not only for wheelchairs but also for carrying carts, carts, and the like.

〔The invention's effect〕

According to the present invention, the wheelchair mounting surface of a wheelchair can be easily formed without requiring an attendant to perform troublesome work. Moreover, since the formation of the wheelchair mounting surface is detected by the switch and the driving means is stopped, the wheelchair mounting surface can be reliably formed, and the wheelchair mounting surface is formed only near the elevator door. It is safe because it is done.
