Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention enables safe transportation of wheelchairs for disabled persons, shopping carts, and other transport vehicles on a stair-stepped conveyor such as an escalator. Concerning the steps of the man conveyor.

[Background of the invention]

Recently, measures to improve services for the disabled in response to welfare-oriented public opinion have been implemented in roads, buildings, and various transit facilities. Typical examples include reducing the level difference between the sidewalk and the road surface, creating gentle slopes connecting floors in buildings, and installing elevators for people with disabilities. On the other hand, one of the measures that is desired to be put into practical use in parallel with these measures is the transportation of wheelchairs using passenger conveyors.

The installation angle and operating speed of conventional passenger conveyors, which are closely related to user safety, are based on the physical strength and motor skills of able-bodied people. Therefore, it is extremely chaotic.

That is, (1) The steps of the passenger conveyor are intended for able-bodied people who ride while standing, and the distance from the center is approximately 40 cm. It is impossible to place a wheelchair 800 to 1,000 cm tall here and keep it level.

(2) The passenger conveyor is based on the premise that the passenger's weight (feet) is supported by steps and one hand grips the handrail, and safety is ensured by maintaining balance through this movement.

(3) It is necessary to transition from a fixed part to a moving part (or vice versa), and for this a certain degree of physical strength and motor skills are essential.

The use of passenger conveyors by wheelchair users and elderly people has many disadvantages in terms of ensuring their safety.

However, since passenger conveyors are installed in the most efficient locations considering the movement of people, there is a demand for transporting wheelchairs using these conveyors. The advantages of passenger conveyors are that they are far superior in terms of investment cost and convenience compared to elevators that are often installed on loose slopes or walls that require a lot of building space, and they ignore safety. It is well suited for wheelchair users.

For this reason, the following modification of the steps of the passenger conveyor has been proposed in the past. The first representative example is
As mentioned above, a row of steps with a thrust of about 40 cm is assembled with steps larger than this, and there is one designed to place a chair on these larger steps. The second representative example is one in which a mechanism is incorporated into the row of steps of the general passenger conveyor shown in FIG. 1 to substantially widen the center of the steps as shown in FIGS. 2 and 3. be.

Here, we will discuss the second proposal in detail and discuss its mechanism and safety.

Figure 1 shows the configuration of a conventional passenger conveyor.
The main body part 1 supporting the entire passenger conveyor includes a handrail part 2 standing upright on both sides of the passenger, a handrail 2a running on the upper end of this part, and a step 3 rotating at the same speed as the handrail part 2a. This step 3 consists of a horizontal tread 3a and a riser 3b, and further includes a front roller 3C and a rear roller 3d on which this step 3 runs.

For such a general passenger conveyor, modification of the step portion shown in FIGS. 2 and 3 has been proposed.

The key point is that one or more mechanisms 4b for lifting a part of the tread 4a of the step 4 are inserted in the 30 rows of steps. In the illustrated example, when the center portion 4c of the tread 4a comes into contact with the upper surface of the guide rail 5, it is provided with a mechanism that raises the height h. The tread surface 4c is arranged only in the area where it is desired to be raised, and when the row 26 comes into contact with the guide rail 5, the tread surface 4c is raised via the support 7.

This method makes it possible to secure a horizontal surface with a length of about 80 cm, which is the sum of the depths of the treads 3a and 4c, and is suitable for carrying wheelchair k.

However, the configuration of FIGS. 2 and 3 is such that the lifting mechanism 4b
It has drawbacks in terms of high cost and safety due to its complexity.

[Purpose of the invention]

An object of the present invention is to provide a step for safely transporting a wheelchair using a passenger conveyor, with a simple mechanism in mind.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

4 and 5, in the present invention, one or more specially shaped steps 9 are inserted into a row of endless steps 3, and the steps 9 themselves are configured to transport the wheelchair k. The step 9 has a first tread surface 9a with a different surface and a second tread surface 9b located on the back side of the first tread surface 9a.
a is joined to the upper end of the riser 9c by a hinge 9d. When loading wheelchair k, use the hinge 9d as shown by arrow A.
As a result, a horizontal surface like the imaginary line Z is formed, and the wheelchair k is
Secure space to carry.

In this case, the different surfaces of the treads 9a and 9b are provided with a ridge made of fine irregularities, and the treads are provided at the entrance and exit, as in the past.
It appears with precise bite.

On the other hand, an imaginary line B indicates a support body inserted separately, which prevents the tread 9a from sinking when rotated. This reduces the charge load on the hinge 9d.

〔Effect of the invention〕

According to the present invention, the stability of the unit can be maintained with simple structural steps, and an inexpensive and safe passenger conveyor can be provided.

Claims (1)

[Claims] 1. In a step of a passenger conveyor that is arranged in an endless manner and has a riser that closes a tread and a rear part, the tread includes a first tread that is joined to the rear part of the step and rotates toward the rear, and a first tread that rotates toward the rear. A step for a passenger conveyor comprising a second tread located below the first tread.
