Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a light-weight coupled transport machine that can be installed in narrow passages or stairs, and is applied to escalators and moving walkways installed in buildings and pedestrian bridges. The aim is to help reduce the burden on pedestrians.

(Conventional technology) As a connected transport machine in which a passenger stands on a step, conventional escalators and moving walkways usually have a horizontal width of 500m for one step alone.
m, it is 1000 mm for two people, including moving handrails,
On narrow stairs with a width of about 1200 mm, it is not possible to realize a reciprocating escalator as well as an escalator in which only ascending is the escalator and descending is the stairs.

Hereinafter, “step” means a so-called “step”, but when its size is referred to, it means “the upper surface of the step”, that is, “the step surface”.

(Problems to be Solved by the Invention) A one-way escalator and moving sidewalk with a width of about 600 mm including a moving handrail, and a reciprocating escalator and moving sidewalk with a total width of about 1200 mm, including a moving handrail, are realized. The main problem is a step structure that enables the passenger to stand stably while making it possible.

(Means for solving the problem) The conventional method in which each passenger faces in the direction of travel and places both feet on one step has been revised, and the size of each step has been reduced to about half that of the conventional one-person type. In FIG. 5, a direction that forms an angle equal to the angle α in FIG. 5 with respect to the advancing direction is taken as the body front, and strides over two adjacent steps, and a moving handrail interlocking mechanism is provided on the step driving mechanism installation side. Determine suitable steps and the structure of the handrail.

At that time, so that the passenger can stand stably,
Of the pair of adjacent steps, a part of the lower step in the inclined traveling portion has a two-step structure, the step is equal to the step difference, and the upper step and the upper step are on the same horizontal plane. To form the boarding area. Note that this is not essential, but a part of the upper step is provided with a narrow step part that can be used as a stage, and a part of the drive mechanism is housed under the upper part and the lower part of the step. It is good to save the size.

(Operation and Example) The operation of the above means will be described with reference to an example.

In the plan view of Fig. 1, the traveling direction is defined as the front-back direction, and the horizontal direction perpendicular to it is defined as the left-right direction.
An example of the structure and dimensions and operation of the ascending escalator limited to m will be described.

The length A of step 1 in the left-right direction is generally in the range of 300 to 450 mm. A is the step pitch P in the horizontal traveling section
Approximately equal to The length B in the front-rear direction is generally in the range of 200 to 300 mm. Now, the area of the step where A = 400mm and B = 250mm is 1000mm, which is 1/2 of the standard value of the escalator for one step in each step. In FIGS. 1, 2, 3 and 5, the lower step and the upper step which constitute the riding area of one occupant in the ascending process are defined as 1, and the upper step is defined as 2 and the half of the step 1 (the right half in the figure) 11 (right and left) The length C in the direction is approximately A / 2, in this case approximately 200 mm, and the length D in the front-rear direction.
Is set to 200 mm), and the step is made equal to the difference S between step 1 and step 2. If the inclination angle θ of the escalator is 30 °, S = Bsin θ = 125 mm. One foot is placed on the leftward portion of step 2 and the upper stage 11 of step 1 respectively. At the right end of Step 2, a step 21 having a narrow left-right width E (in this example, a left-right width E = 200 mm, a front-rear width F = 200 m)
m), the level difference is equal to the step S, and the upper surface is used as a stage. A part of the drive mechanism is housed below the upper stage 11 and the step portion 21.

Assuming that the passengers all stand in the same direction, the moving handrail 2 may be provided on only one side (the stepped side) in the traveling direction.

In the case of an escalator that only raises or lowers, a conventional drive mechanism may be used, but a patent application No. 1-230458 “Connected transfer machine” or a patent application No. 1-241770 by the present applicant is applicable.
As shown in FIG. 4, the use of the "joint-type transport machine" enables the ascending and descending to be constituted by a series of step trains, a series of moving handrails can be used, and the depth of the entire apparatus is small. It can be installed on conventional stairs with simple construction. In addition, since the width of the step in the front-rear direction is small, the radius of the turning portion can be reduced, and the pin-shaped teeth (the teeth of the step are the first and the first) provided on each moving body (step and moving handrail unit).
Drive gears (steps 5 and 7 in FIGS. 5 and 7 for stepping drive, and FIG. 7 for driving the handrail unit in FIG. 7). 6) can be reduced, and there is no unreasonable mechanism. FIG. 7 shows a mobile handrail unit 4 connected by a universal joint to simplify the structure.
Is equal to the step pitch P, and the step drive gear 5 and the moving handrail unit drive gear 6 have the same pitch circle diameter and tooth profile. , Via a bevel gear 8.

In the case of the reciprocating escalator, as shown in FIG. 6, the center of the tooth profile of the driving pin-shaped teeth 33 provided at each step and the center of the pin 310 of the bending portion of the driving link 31 are both G from the right end of each step. (In this example, 50 mm), the distance H between the center of the gear and the center of the pin 310 is determined by the pitch of the step. P (equal to the pitch of the drive link and approximately equal to the front and rear width B of the step), the distance K from the center of the gear 5 to the left end of the step is A +
BG = 400 + 250-50 = 600 mm, and the total width of the reciprocating escalator is 1200 mm at 2K, which satisfies the conditions originally set forth.

In the straight section upstairs and downstairs, the stepless portion of the step enters the underfloor after engaging with the comb-shaped part (comb) at the terminal, but the stepped portion may remain exposed on the floor.

On a moving sidewalk without a slope, there is no step at each step.

(Effects of the Invention) Since the present invention can be applied to narrow stairs and passages, it can also be applied to relatively small buildings and pedestrian bridges, and can be saved for the elderly and the sick. In particular, there is an effect of increasing the use of a pedestrian bridge that is becoming a useless long object with few users.
