Description

The present invention relates to a moving handrail for an intermediate high-speed passenger conveyor.

A conventional handrail for an intermediate high-speed passenger conveyor will be described with reference to the drawings. FIG. 7 is a schematic view of the moving handrail shown in the patent document.

In FIG. 7, reference numeral 12 denotes a moving handrail portion that moves in synchronization with the moving step, which is covered with a high modulus elastic body 13 and changes the distance between the moving handrail portion 12 and the handrail guide rail 10 to change the link mechanism, thereby moving the handrail body. The portion B of 13 is contracted at the low speed portion and expanded at the high speed portion, and the surface of the moving handrail body is flat regardless of the stretched state.

However, the technology configured as described above has the following problems. Since there is only one handrail guide rail, when the distance between the handrail moving body and the handrail guide rail is increased in the low speed portion, a sufficient driving force cannot be transmitted to the handrail moving body side without the traveling roller, and smooth traveling cannot be performed. There is a fear. In a high-speed portion with a long distance, the distance between the moving handrail body and the handrail guide rail becomes narrow, but the pin at the lower portion of the moving handrail and the center of the traveling roller are not aligned on a straight line, and the driving force is dispersed. Furthermore, there is a problem that the apparatus becomes large in the vertical direction of the moving handrail.

The present invention has been made to solve the above-mentioned problems, and has a simple structure and is synchronized with the moving speed of the steps of the intermediate high-speed passenger conveyor, and is slow in the vicinity of the entrance and exit, and fast in the middle part. And providing a moving handrail that is smooth and does not feel uncomfortable.

In a handrail of a passenger conveyor having a high-speed part and a low-speed part in a step, a handrail roller rotatably supported by a handrail roller pin on one side of every two links of a roller chain that is arranged in the direction of the handrail and circulates endlessly; An auxiliary roller that has a U-shaped handrail roller guide that rotatably guides the handrail roller, and is rotatably supported by an auxiliary roller pin on the opposite side of the handrail roller at one intermediate link between adjacent handrail rollers; A roller attachment that has a U-shaped auxiliary roller guide that rotatably guides the auxiliary roller, and is rotatably supported by a handrail roller pin on both outer sides of the roller chain link of the handrail roller portion and directed toward the handrail side; The moving handrail gripped by the passenger is made an elastic body that can be stretched and fixed to the elastic body fitting attached to the elastic body, and when the moving handrail is viewed from the side, the handrail roller guide Thereby stretching the moving handrail made of an elastic material is also to change the distance between the handrails rollers adjacent changing the interval auxiliary roller guide.

In the present invention, handrail rollers and auxiliary rollers are alternately arranged on the outer side of the roller chain, and each roller guide is dedicated, so that the transmission from the transmission unit to the low-speed unit and from the low-speed unit to the transmission unit can be smoothly performed. Since the roller chain is in a straight line, the driving force is also in a straight line, a sufficiently uniform extension force is given to the elastic body of the moving handrail, the handrail surface is smooth and uncomfortable, and the apparatus is downsized. Furthermore, since a roller chain is used, it is possible to drive a sprocket and to obtain a stable running without slipping and slipping with the steps that were usual.

Hereinafter, description will be given based on the embodiment of the present invention. FIG. 1 is a cross-sectional view of a high-speed handrail roller. FIG. 2 is a cross-sectional view of the high-speed part auxiliary roller. FIG. 3 is a cross-sectional view of the low speed roller. FIG. 4 is a side view of the low speed roller chain. FIG. 5 is a side view of the high speed roller chain. FIG. 6 is an end side view of the moving handrail of the intermediate high-speed passenger conveyor. FIG. 7 is a schematic diagram of a moving handrail of a conventional intermediate accelerating conveyor shown in Patent Literature.

In FIG. 1, a handrail roller 7 that is rotatably supported by a handrail roller pin 6b on one side of every two links of a roller chain 8 that is arranged in the direction of the handrail and circulates endlessly, and a handrail roller 7 is rotatably guided. A roller attachment 3 having a U-shaped handrail roller guide 5, rotatably supported by handrail roller pins 6 b on both outer sides of the low chain 8 link of the handrail roller portion, and rotated toward the handrail side, and a movement grasped by the passenger The handrail is an elastic body 1 that can be stretched and the elastic metal fitting 2 attached to the elastic body 1 is fixed.

1, 2, and 5, a rotatable auxiliary roller 10 that is pivotally supported by an auxiliary roller pin 6 a on the opposite side of the handrail roller 7 to an intermediate link between adjacent handrail rollers 7, and rotatably guides the auxiliary roller 10. A U-shaped auxiliary roller guide 4 is provided. The handrail roller guide 5 and the auxiliary roller guide 4 are supported and fixed by a handrail support material 9.

In FIG. 6, the case where the upper part of the moving handrail is traveling in the right end direction will be described. In the high-speed part, the endless roller chain 8 is straight when viewed from the side, and the handrail roller 7 and the auxiliary roller 10 alternately arranged for each link on the outer side of the roller chain 8 are fixed to the handrail support material 9. The U-shaped handrail roller guide 5 and the auxiliary roller guide 4 are rotatably guided. At this time, the distance between adjacent handrail rollers 7 is also maximized, the distance between the elastic metal fittings 2 fixed to the roller attachment 3 is also maximized, and the moving handrail speed is also maximized. The degree of expansion of the elastic body 1 that can be expanded and contracted constituting the moving handrail is also maximized. In the high speed section, the size of the handrail device in the vertical direction is minimized.

When viewed from the side of the moving handrail that has shifted from the high-speed portion having a long distance to the speed change portion, the auxiliary roller guide 4 moves downward and gradually separates from the handrail roller guide. At this time, the distance between the adjacent handrail rollers 7 is gradually narrowed, the distance between the elastic metal fittings 2 fixed to the roller attachment 3 is gradually narrowed, and the moving handrail speed is also decreased.

The moving handrail that has shifted from the speed change portion to the low speed portion also minimizes the distance between adjacent handrail rollers 7, minimizes the moving handrail speed, and minimizes the extension of the elastic body 1. FIG. 3 shows a cross section of the low speed roller, and FIG. 4 shows a side surface of the low speed roller chain. The handrail that reaches the end loop part moves at a low speed along the loop shape to the lower end of the loop.

The moving handrail that has moved to the lower loop end portion at a low speed enters the return-side transmission section, gradually decreases the distance between the handrail roller guide 5 and the auxiliary roller guide 4, and the distance between the adjacent handrail rollers 7 also increases. 1 also stretches and the movement speed increases.

In the moving handrail that has shifted from the return-side transmission unit to the return-side high-speed unit, the roller chain 8 is in a straight line, the distance between adjacent handrail rollers 7 is maximized, the elastic body 1 is also expanded to the maximum, and the moving speed is maximized. . By providing the drive sprocket in this section where the roller chain 8 is in a straight line, stable running without slipping can be obtained.

The moving handrail of the intermediate high-speed passenger conveyor constructed as described above has a simple structure, and smooth acceleration / deceleration can be obtained by changing the distance between the guides from low speed to high speed. Can provide something with no sense of incongruity.
