Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an escalator, and particularly to an escalator suitable for allowing wheeled vehicles such as wheelchairs and carts to ride in a stable state.

In today's world where we are aiming to create a highly advanced 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. Particularly in recent years, escalators have been recognized as an indispensable means of transportation within buildings, and it is expected that escalators will emerge that can be easily used by disabled people and the elderly. However, at present, the installation angle and operating speed, which have a large 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 the agility to get on and off the escalators. For these people, it is necessary to reduce the installation angle to increase the sense of stability while riding, or to reduce the operating speed to make it easier to get on and off the escalator. . In addition, for people who have difficulty walking and use wheelchairs, there is a need for escalators that have special consideration so that they can be used while in a wheelchair.

Furthermore, in department stores, etc., it was not possible to safely ride the shopping cart with the shopping cart still inside. This is because wheelchairs and carts have wheels and generally do not ride stably on stepped treads. 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 view of the above points, the present invention provides an escalator that has a simple structure and allows a wheelchair or a cart to ride the escalator with peace of mind.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

Fig. 1 shows the configuration of a conventional escalator, which includes a main body part 1 that holds the entire escalator, a handrail part 2 that stands upright on both sides of the passenger, and a handrail 2a that rotates at the upper end of the handrail part 2. ,
A step 3 rotates at the same speed as the handrail 2a to carry passengers, and the step 3 consists of a tread 3a for passengers to ride on and a riser plate 3b, and a front roller 3c and a rear roller for smoothly rotating the step 3. It is composed of 3D etc. All of the structures of these escalators are well known, but the present invention is characterized in that two steps 3 are arranged horizontally, as shown in FIG.

In other words, by configuring two steps 3 horizontally, two treads 3a each having a depth L of about 400 mm can be maintained in a horizontal state, so that the entire tread has a horizontal surface of about 800 mm. This results in a stair-like structure. On this horizontal tread with a width of about 800 mm, there are the front wheels Ka of wheelchair K,
You can ride on the rear wheel Kb joint. (According to the JIS standard, the dimensions of the wheelchair are 1015mm in total length, 650mm in width or less, and the distance between the front and rear wheels is approximately 500mm.The front wheels are small in diameter, and the rear wheels are large in diameter because they are rotated by hand. ) Therefore, wheelchair K is stably transported in a horizontal state.

Note that the guide rail 5 for guiding the step 3 is located behind the rear roller 3 of the step 3 in the upward direction.
In addition to the guide rail 5c that guides the guide rail 5c and the guide rail 5d that guides the front roller 3c, there is a rear roller 3d of the step 3 on the lower side that is forward in the upward direction.
It is composed of two sets: a guide rail 5a that guides the front roller 3c, and a guide rail 5b that guides the front roller 3c.

By guiding the two adjacent steps 3 by such two sets of guide rails 5a to 5d, the treads of each step are expanded so as to be flush with each other.

In addition, since the steps 3 are all steps of the same shape, the tread can be expanded simply by adding a guide rail. Therefore, the configuration is extremely simple, and each step has its own guide rail. Due to the guided configuration, heavy objects such as wheelchairs can be stably supported.

According to the present invention described above, it is possible to transport a wheelchair in a stable horizontal state with a simple structure, and it is also possible to transport not only a wheelchair but also a shopping cart in a department store, etc. in a stable horizontal state. You can expect significant results.

[Brief explanation of the drawing]

Claims (1)

[Claims] 1. In an escalator equipped with a large number of steps of the same shape that are arranged in an endless manner and rotate, a plurality of sets of guide rails for guiding the steps are provided above and below, and the same number of the steps are attached to the plurality of sets of guide rails. It is characterized by guiding the steps at the front in the ascending direction to the lower guide rail and the steps at the rear to the upper guide rail, thereby making the treads of each plurality of steps flush. escalator.
