Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to steps for a passenger conveyor suitable for transporting a wheelchair.

[Background of the invention]

In today's world where we are aiming to create a highly welfare environment, it is desirable to adopt transportation systems and architectural structures that are specially devised so that even people with disabilities can move around relatively freely. Especially recently,
With the recognition that escalators are an indispensable means of transportation within buildings, it is expected that escalators will emerge that can be easily used by the physically handicapped and the lame elderly.

However, as it currently stands, the installation angle and driving speed, which have a major impact on the psychology of escalator users, do not cause any inconvenience to the general public, but elderly people and people with physical disabilities lack agility when getting on and off the escalators. Therefore, escalators cannot be used by these people, so we have adopted measures such as reducing the installation angle to increase the sense of stability while riding, and slowing down the operating speed to make it easier to get on and off. There is a need. In addition, for people who have difficulty walking and use wheelchairs, there is a need for a passenger conveyor that has special consideration so that they can be used while in a wheelchair.

Furthermore, in places such as Tebert, it was not possible to ride the Yanagawa cart with confidence even if the cart was still there.

This is because wheelchairs and carts tend to have wheels, and generally lff
This is because it does not come stably on the tread surface having ff1. In addition, until now, there are some types of roads that are generally called electric roads and do not have a step on the tread, but the drawback is that the entire tread slopes like a slide, making it unstable for wheelchairs, and the entire equipment requires a long journey, making it difficult to take up space. It has the disadvantage of poor efficiency.

In order to improve this drawback, the inventors of the present invention previously proposed a passenger conveyor on which a single chair can be placed.

The explanation will be given below based on the figures.

Figure 1 shows the configuration of a conventional passenger conveyor, which includes a main body part 1 that supports the entire passenger conveyor, a handrail 2 that stands upright on both sides of the visitor, and a handrail 2a that runs on the upper end of this handrail 2. , it is common to have a step 3 that rotates at the same speed as this. The step 3 is composed of a horizontal tread surface 3a and a riser 3b, and is further provided with a front roller 3c and a short side roller 3d on which the step 3 runs.

Although the configuration of the passenger conveyor described above is well known, the configuration shown in FIGS. 2 and 3 has been proposed as a means for transporting a wheelchair on the oak passenger conveyor. This configuration has one step 4 in a row of steps 3, which is equipped with a mechanism 4b for lifting a part of the tread 4a and a closing plate 4d integrated therewith.
One or more are inserted. The general structure of this is as follows: When the center part 4c of the tread 4a comes into contact with the upper surface of the guide rail 5, it rises by a height h. The rail 5 is disposed only at the part where it is desired to raise the central part 4c, and when the roller 6 comes into contact with this industrial rail 5, it is raised via the support 7.

This height h is the same height as the adjacent step 3 in front, which brings wheelchair K closer to a horizontal position. By adding the length of the steps 4 to 400vtx, a space of about 800m is essentially secured.

However, with the space of about 800 m secured as mentioned above, it was found that wheelchair K can only be used for infants, and that wheelchairs for adults require about 1000 to 1200 mm, as shown in Figure 3. It has been confirmed that it reaches Step 4, Step 3 adjacent to Step 4, and another Step 3. For this reason, when an adult wheelchair K is carried, the rear wheels Ka rest on the central part 4C of the tread 4a, and further forward, the lower end of the footrest Kb touches the tread, and the important front wheel KC is suspended by a gap g. As a result, the armrest l
(D and seat Ke are tilted and their center of gravity moves backwards, causing the problem of them sliding down in the direction of the arrow.In order to prevent f# from falling in the direction of the arrow, the tour conductor M has to do his best.) In the worst case scenario, wheelchair K and tour conductor M may fall into an accident.

As a result of the above, the following improvements will become membership fees.

1. The inclination of the wheelchair K poses a serious safety hazard for everyone including the tour conductor M, making it unsuitable for general use.

2. Since the lower end of the footrest 4b (made of gold Ii4) and the tread surface (made of metal) are in strong contact, it is not just that it makes an unpleasant tactile sound, but that both of them are worn out.

[Purpose of the invention]

The present invention has been made to improve the above problems.

[Summary of the invention]

The present invention provides a passenger conveyor with endless rotating steps, in which at least one of the steps is provided with a lifting mechanism for raising the step, and the rear wheels of the wheelchair are placed on the step. , the footrest for the wheelchair is placed on the two steps in front, and the ease of the rising treadle is such that when the wheelchair is placed on it, the wheelchair becomes almost horizontal due to the rear wheels and the footrest. The step in front of you is one step higher.
It was raised by

[Embodiments of the invention]

The present invention will be explained below based on the drawings of one embodiment.

4 and 5, in the present invention, in addition to the rising height h of the rise 1@4b of the step 4 explained in the third figure, ha
By increasing the height of the step 3 that touches the momentary step 3, the height of the step 3 is also increased, thereby keeping the wheelchair K level. A contact piece B made of a synthetic resin that does not make noise or wear out even if it comes into contact with the footrest 4b and has properties that are difficult to remove is placed at a position that coincides with the footrest 4b.
There are signs. In this case, the specific dimensions of the elevation ha are determined from the specifications of wheelchair K, and are determined from the relationship between the normal height of the steps 3 of the Shiman conveyor and the dimensions of wheelchair K. The dimensions are such that the seat Ke is approximately horizontal.

On the other hand, if the color tone of the contact piece B is different from the color of ordinary steps and is used for positioning the wheelchair K in the front and back and left and right directions, the usability of the contact piece B will be further increased.

By doing this, 1. Wheelchair K (for adults) can come horizontally, which not only prevents it from sliding in the direction of the arrow as explained in Figure 3, but also reduces the burden on tour conductor M and increases safety. can be achieved.

2. Easily determine the position for wheelchair K.

3. The steps are not damaged due to contact with the footrest Kb.

There are effects such as

〔Effect of the invention〕

According to the present invention described above, there is an advantage that it can be safely used in a wheelchair or the like.

In addition, in the above explanation, the guide rail 5, roller 6, etc. were used for the raising mechanism 4b, but the present invention is not limited to this, and a hydraulic mechanism or a spring mechanism may be used below the central portion 4C to move it in the vertical direction. It may be a flat surface, or it may be one in which the entire tread surface rises.
