Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail device for a passenger conveyor, and more particularly to a handrail device for a passenger conveyor in which a straight path and a curved path are combined to form a path.

[0002]

Escalators and moving walkways are known as passenger conveyors. This escalator and moving walkway
Almost all of the practical ones are straight paths, and the handrail device is also arranged in a straight line.

As an escalator assuming a curved path,
Japanese Unexamined Patent Publication No. 58-212579 (hereinafter, referred to as prior art 1) is known. The escalator disclosed in this publication is an escalator having a constant curvature, and the handrail device also has a constant curvature in conformity with the footboard portion.

Further, in Japanese Unexamined Patent Publication No. 8-208169 (hereinafter referred to as Prior Art 2), handrail devices having different transport speeds are arranged in series in a variable speed moving walkway, and each handrail device is divided. It is disclosed that a brush is arranged in a gap between parts and a brush comb device is provided to ensure safety of movement of a passenger's hand between handrails.

[0005]

However, in the invention of the prior art 1 described above, each time the curvature of the curved path changes,
It was necessary to form a dedicated handrail, and it was necessary to deal with the change in the handrail length of the curved portion in the same manner. Therefore, there is a problem that the specifications of the handrail device are limited and, at the same time, it is costly to cope with the specification change.

Further, in the prior art 2, since the handrail device is not continuous, there is a region without a handrail. Also, in this handrail-free area, passengers must take their hands off the handrail at any time.
There is a problem that it is not always safe.

SUMMARY OF THE INVENTION The present invention provides a handrail device for a passenger conveyor, which can cope with a curved path having an arbitrary curvature and is intended to safely move a passenger at a branch portion of a handrail.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the drawings.
I will explain.

FIG . 1 is a side view of a passenger conveyor handrail according to the present invention.
In the floor plan of the table, handrail 1 for straight route and handrail for curved route
2 shows a part of the transport path consisting of 2 and 2.

Handrail 1 for straight path and handrail 2 for curved path
Has a separate handrail device,
Reference numeral 3 denotes a tread plate composed of end portions 3a and 3b having different curvatures, and a plurality of the tread plates 3 are connected to the entire conveyance path so as to move in the arrow direction.

The handrail 2 of the curved path is disposed inside the handrail 1 of the linear path with a predetermined gap formed at the branch portion A of the handrail.

FIG . 2 is an enlarged plan view of the branch portion A of FIG.
is there.

Handrail 1 for straight path and handrail 2 for curved path
Means that a gap L, which is more than twice the thickness of a human finger, is formed, and this gap L and the outer arrangement of the rear handrail allow passengers to approach the split A while holding the handrail in a straight path. However, since the passenger's fingers are not caught in the divided portion A and the passenger's body is supported by the handrail which is in the ascending stage, there is no involvement.

FIG. 3 is a side view of the handrail device for a passenger conveyor according to the present invention, in which a split portion A between a handrail 1 having a straight path and a handrail 2 having a curved path has an overlapping arrangement.
The grip height B1 of the handrail 2 on the curved path is formed to be lower than the grip height A2 of the descending portion a of the handrail 1 on the straight path. Further, the grip height C1 of the handrail 1 on the straight path on the right side of the figure is formed to be lower than the grip height B2 of the descending portion B of the handrail 2 on the curved path.

The setting of the handrail grip height at this split portion is A2 when A1 = A2 = C1 = C2.
= B1 + α, B2 = C1 + α, or in other cases, if A1 + α = A2, C1 + α = C2, and A1 = C2, A1 = B1 = B2 = C2. However, α is a value approximately equal to the handrail thickness of the conventional straight path.

With this structure, the handrails have a structure in which the handrails are overlapped with each other when viewed from the side in the part where the handrails are divided, and there is no break in the conveying direction.
The continuity of the handrail can be secured.

Even if the timing of the handrail change operation at the descending portion is delayed due to the difference in height, part of the palm or the wrist touches the ascending portion of the front handrail, and the hand is smoothly changed.

As described above, the drive structure of the handrails 1 and 2 used for the straight path and the curved path is not particularly limited,
The point is that the structure is such that the handrail can be moved.

An embodiment of the handrails 1 and 2 suitable for use in a straight path and a curved path will be described below.

FIG. 4 is a plan view of the handrail 2 of the curved path,
Reference numeral 2a is a plurality of handrail cover blocks forming a handrail cover (grip), and the plurality of handrail cover blocks are connected by a bellows 2b to prevent the handrail cover block 2a from being caught in a gap between the handrail cover blocks 2a. .

FIG. 5 is a side view showing a handrail block driving mechanism for moving the handrail cover block, which is provided in the end sections A and B of the handrail 1 of the straight path or the handrail 2 of the curved path of FIG. .

The drive mechanism of the handrail block is composed of a pair of a drive sprocket 4 whose one end is rotated by power from a motor (not shown) and a floating sprocket (not shown) which is arranged at the other end, and is arranged on both sides of the path. The handrail block continuum is hung between the drive sprocket and the floating sprocket, and the horizontal axis of the handrail block (described later)
Is engaged with the claw portion 4a of the drive sprocket 4 and the floating sprocket arranged at the other end to move the handrail block or the handrail cover.

In the handrail 1 of the straight path, the handrail speeds on both sides are the same as the moving speed of the footboard portion 3, but in the handrail 2 of the curved path, the moving speeds are different between the outer side and the inner side according to the turning radius. Be transported.

FIG. 6 is a plan view of a handrail block used in the handrail device of the present invention. 1a is a handrail cover block for the handrail 1 having a straight path, which is made of synthetic resin such as plastic. A plurality of the handrail cover blocks 1a are arranged in the carrying direction and are connected by a bellows 1b.

A plurality of handrail blocks 5 are provided inside the handrail cover block 1a.

The handrail block 5 comprises a first U-shaped block 7 having a connecting bracket 6 at the front end and a second C-shaped block 9 having a connecting bracket 8 at the rear end.

The first U-shaped block 7 is fitted on the outer periphery of the second U-shaped block 9 and the both side portions are connected by the horizontal shaft 10. The adjacent second U-shaped block 9 is connected by a vertical axis 11 to form a continuous body structure.

The first U-shaped block 7 is fixed to the handrail cover block 1a at a predetermined pitch by locking means such as screws.

A horizontal shaft 10 connecting the first U-shaped block 7 and the second U-shaped block 9 engages with the claw portions 4a of the drive sprocket 4 and a floating sprocket (not shown), and The shaft 10 allows vertical bending between the handrail blocks 5 and effectively winds around the driving sprocket 4 and a floating sprocket (not shown) to generate a driving force.

The vertical axis 11 allows horizontal rotation between the handrail blocks 5 and forms the curve of the handrail 2 in a curved path.

FIG. 7 is a cross-sectional view taken along the line AA of FIG. 6, in which the lower portions of the first and second U-shaped blocks 7 and 9 are fitted into guide rails 13 provided along the conveying path. It is structured to move. The guide rails 13 are endlessly formed in units of the transport path, but neither the drive sprocket 4 nor the floating sprocket is formed in any part.

FIG. 8 shows the first and second U-shaped blocks 7 of the handrail block 5 used in the handrail device of the present invention.
9 is a plan view showing a state of moving along a curved path.

The vertical rotation between the first U-shaped block 7 and the second U-shaped block 9 is performed by the horizontal shaft 10 as described above.
Rotate around. Further, the rotation in the left-right direction (horizontal direction) between the first U-shaped block 7 and the second U-shaped block 9 rotates about the vertical axis 11.
By the above-described rotation around the two axes, the structure is such that the first and second U-shaped blocks 7 and 9 can be displaced vertically and horizontally.

The handrail cover block 1a (2a)
Mutual vertical and horizontal displacements correspond to each other by the bellows 1b (2b).
