Abstract

PURPOSE:To enable the application in a relative small building and an overbridge, and help the aged and the sick by forming a conveyor so that a man can ride over two steps adjacent to each other and can stand in one line with the front of a body facing in the direction transverse to a moving handrail and without the generation of interference. CONSTITUTION:Steps 1, 2 respectively having a length B in the progressing direction at 200-300mm and a length A in the horizontal direction transverse to the progressing direction at 300-450mm in a plan are connected. A moving handrail coupling mechanism is provided in the step driving mechanism side to form a conveyor so that each passenger can ride over two steps 1, 2 adjacent to each other with the front of a body in the direction transverse to the moving handrail and can stand in one line without the generation of mutual interference. With this structure, application to a stairway and a road having a narrow width is possible, and therefore can be applied to a relative small building and an overbridge.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a light connected transport machine that can be installed in narrow aisles and stairs, and is applicable to escalators and moving walkways installed in buildings and on pedestrian bridges. The aim is to help reduce the burden on pedestrians.

(Prior art) In conventional escalators and moving walkways, where the passenger stands on the step, the left and right width of the step is usually 500 mm.
+++m, for a two-person type, it is 1000 mm, and if you include the moving handrail, it is impossible to make a narrow staircase with a width of about 1200 mm, let alone a reciprocating escalator, or an escalator that only goes up as an escalator and goes down as a staircase. be.

(Problems to be Solved by the Invention) A one-way escalator and a moving walkway that are narrow in the direction perpendicular to the direction of travel and have a width of about 600 mm including the sliders, and a two-way escalator and a moving walkway with a total width of about 1200 mm. The main problem is a step structure that makes it possible to realize this and also allows a passenger to stand stably.

(Means for Solving the Problem) The conventional system in which each passenger faces the direction of travel and places both feet on a step is changed, and the structure of each stellar slide is determined.

At that time, in order to allow the passenger to stand stably, a part of the lower step in the inclined running part of the pair of adjacent steps is made into a two-tiered structure, and the difference in level is the difference in level between the steps. Equally, a part of the chip accommodates a narrow step that can be used as a stage to save on lateral dimensions.

C (Actions and Examples) The effect of the above means will be explained using examples.

In the plan view of Figure 1, the direction of travel 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/dimensions and operation of an ascending escalator limited to lam will be explained.

The length of step l in the left and right direction A is approximately 300 to 450
Take the range of iv. The width is approximately equal to the pitch P of the steps in the horizontal running section. The length B in the front and back direction is approximately 2
The range is 00 to 30oIII11. Now A=40
The area of the step when 0mm and B=250mm is 100
0mm, each step - passenger escalator -
It becomes 1/2 of the standard value. In Figures 1.2.3 and 5, the lower step that constitutes the passenger-person boarding area in the ascent stroke is designated as 1, the upper step as 2, and step 1.
Half part (right half in the figure) l! (The length C in the left-right direction is approximately A/2, and in this example, it is approximately 200 mm, and the length D in the front-rear direction is also 200 mm.) is the upper step, and the difference in step is the step between step 1 and step 2. Make it equal to the difference S. If the inclination angle θ of the escalator is 30°,
S = B sin θ - 125 mm. Step 2
Place one foot on the left side of the step 1 and on the upper stage II of step 1. Narrow step 2 with horizontal width E at the right end of step 2
1" (in this example, the left-right width E = 200 mrtr and the front-rear width F = 200 mm), the step difference is equal to the step S, and the upper surface is used as a stage. Upper step II and step section 21 A part of the drive mechanism is stored at the bottom of the.

Assuming that all passengers stand in the same direction, the slider rail 2 only needs to be provided on one side (the side with steps) in the direction of travel.

In the case of an escalator that only descends rather than ascends, a conventional drive mechanism may be used, but the patent @

As shown in the figure, the ascending and descending steps can be configured with a series of step rows, a series of sliders can be used, and the overall depth of the device is small, so it can be installed on conventional stairs with simple construction. becomes possible. In addition, since the width of the step in the front and back direction is small, the radius of the turning part can be made small. Reduce the drive gear (33 in Fig. 7, teeth of the slider slide unit 41 in Fig. 7) meshing with (5 in Figs. 5 and 7 for step drive, 6 in Fig. 7 for slider slide unit drive). It can be done, and it is mechanically reasonable. The structure shown in FIG. 7 is driven through a step drive gear 5, a slider sliding unit 81, and a bevel gear 8.

In the case of a reciprocating escalator, as shown in FIG. 6 (50 mm in this example) from the right end of The distance H from the center of the pin 310 is equal to the step pitch P (which is good for the drive link hit, and the step pitch is 11.
1j rear width B), so the distance from the center of gear 5 to the left end of the step is A-1 to n-G = 40.
0+25050=600n+m, and the total width of the reciprocating escalator is 1200mm, which satisfies the initially stated two-track property.

At the top of the stairs and the straight section above the stairs, the unstepped part of the step engages the comb-shaped part (coal) at the end and then goes under the floor, but the step part remains exposed above the floor. good.

On moving walkways without sloped running sections, steps are not provided.

(Effects of the Invention) Since the present invention can be applied to narrow stairs and passageways, it can also be applied to relatively small buildings and pedestrian bridges, which will be a relief to the elderly and infirm. In particular, it has the effect of increasing the use of pedestrian bridges, which are becoming almost useless due to the low number of users.
