Embodiment 1. 1 is a side view showing a main part of a moving handrail device for a variable speed passenger conveyor according to Embodiment 1 of the present invention, and FIG. 2 is a sectional view taken along line II-II in FIG.

In the figure, a balustrade (not shown) of a variable speed passenger conveyor is provided with a rigid guide 1 made of a rigid body such as metal. The rigid guide 1 is provided with a handrail main body 1a that extends along the passenger transportation path and is formed in a shape that is easily gripped by the passenger. The handrail main body 1a has, for example, an elliptical cross section that is flat in the horizontal direction.

A loop-shaped telescopic handrail 2 which is circularly moved along the handrail main body 1a is provided on the rigid guide 1 so as to cover the handrail main body 1a along the outer peripheral surface of the handrail main body 1a. The extendable handrail 2 is made of a flexible material including a large number of communicating voids and is extendable in the longitudinal direction.

To the rigid guide 1, a screw rod 3 extending in parallel with the moving path of the telescopic handrail 2 is fixed via a screw rod supporting portion 4. The screw rod 3 is fixed to the screw rod support portion 4 so as not to rotate. A pair of guide bars 5 extending in parallel with the moving path of the telescopic handrail 2 are fixed to the rigid guide 1.

A plurality of inner bands 6 are fixed to the surface of the telescopic handrail 2 which is in contact with the handrail main body 1a at intervals in the longitudinal direction of the telescopic handrail 2. On the outer peripheral surface of the telescopic handrail 2, a plurality of outer bands 7 are attached so that the telescopic handrail 2 is sandwiched between the telescopic handrail 2 and the inner band 6.

A plurality of driven elements 8 are attached to the extendable handrail 2 via an inner band 6. The driven element 8 is
It has a holder 9 and a rotary moving body (nut member) 10 held by the holder 9. The rotary moving body 10 is screwed into the screw rod 3, and is rotated around the screw rod 3 to move in the axial direction of the screw rod 3. The holder 9 allows the rotation moving body 10 to rotate, and the rotation moving body 10
Along with the movement of, the guide bar 5 guides it to move. Further, the rotary moving body 10 is provided with a notch 10a that allows the threaded rod support portion 4 to pass therethrough.

The rotary moving body 10 is rotated by a conical rotating body 11. The outer peripheral surface of the conical rotating body 11 is the rotating moving body 1.
It has a conical portion (cone portion) 11a in contact with the outer peripheral surface of 0. The conical rotor 11 is rotated about the axis of the conical portion 11a by a drive motor (not shown). As a result, the rotary moving body 10 is rotated about the screw rod 2.

The drive unit 12 has a conical rotary member 11 and a drive motor, and moves the driven element 8 at different speeds depending on the position of the passenger's transport path, and circularly moves the telescopic handrail 2.

FIG. 3 is a sectional view taken along line III-III of FIG. 2, and FIG. 4 is a front view showing the inner band 6 and the outer band 7 of FIG. The inner band 6 is made of metal, for example,
It is slid along the outer peripheral surface of the handrail main body 1a. Since the inner band 6 is provided with the plurality of thin portions 6a,
It has a function as a leaf spring. That is, the inner band 6
Is slid along the handrail main body 1a while gripping the handrail main body 1a by its own elastic force (while frictionally contacting the handrail main body 1a). The outer band 7 is made of a flexible material such as a plastic strap.

FIG. 5 is a plan view showing a fragment of the extendable handrail 2 of FIG. 1, and FIG. 6 is an enlarged perspective view showing a part of FIG. The stretchable handrail 2 is made of a three-dimensional woven fabric in which fibers are three-dimensionally woven over the entire circumference thereof. The three-dimensional woven fabric has a plurality of hexagonal gaps 13a which are regularly formed and which are stacked and arranged at intervals (here, 2
Layer) and a large number of warp yarn portions 14 connecting between the adjacent plane layers 13.

The surface of the three-dimensional woven cloth is finished smoothly in order to obtain a good feel. Further, the space 13a of the three-dimensional woven cloth is large enough that the passenger does not touch the handrail main body 1a through the space 13a even when the space 13a is widened.

Furthermore, the three-dimensional woven fabric is excellent in stretchability, and in particular, it is possible to construct it so as to have a stretch ratio of about 4 times in the arrow direction of FIGS. 5 and 6.
Therefore, by setting the direction of the arrow in FIGS. 5 and 6 as the moving direction of the telescopic handrail 2, the elasticity in the moving direction of the telescopic handrail 2 can be improved.
It is possible to secure enough in any part of the entire circumference.

Next, the operation will be described. Cone 11
The outer peripheral surface of a is in frictional contact with the outer peripheral surface of the rotary moving body 10, and the rotary moving body 10 is rotated about the screw rod 3 by the rotation of the conical rotary body 11. Since the rotary moving body 10 is screwed onto the threaded rod 3, it is moved along the threaded rod 3 by rotation. Since the rotary moving body 10 is connected to the telescopic handrail 2 via the holder 9 and the inner band 6, when the rotary moving body 10 moves, the telescopic handrail 2 also moves along the handrail main body 1a.

At this time, since the diameter of the conical portion 11a gradually increases from one end to the other end, the rotation speed of the rotary moving body 10 caused by rotating the conical rotating body 11 is equal to that of the conical portion. The speed gradually increases from the small diameter portion of 11a to the large diameter portion. That is, the rotational speed of the rotary moving body 10 increases as it moves from left to right in FIG. Since the screws of the screw rod 3 have the same pitch, the moving speed of the rotary moving body 10 gradually increases as the rotating speed increases. The distance between the adjacent driven elements 8 also changes as the moving speed of the driven elements 8 changes, but this change in distance is absorbed by the expansion and contraction of the expandable handrail 2.

Thus, the moving speed of the telescopic handrail 2 is changed according to the diameter of the conical portion 11a. Therefore, by setting the diameter of the conical portion 11a and the rotational speed of the conical rotating body 11 according to the moving speed of the tread (not shown), the moving speed of the telescopic handrail 2 can be changed according to the tread. The passenger is stably transported by grasping the handrail main body 1a from above the telescopic handrail 2.

In such a moving handrail device, since the telescopic handrail 2 composed of a three-dimensional woven fabric is used over the entire circumference,

Embodiment 2. Next, FIG. 7 is a configuration diagram showing a fragment of a telescopic handrail according to Embodiment 2 of the present invention.
In the first embodiment, the expandable handrail 2 made of three-dimensional woven cloth is shown, but in the second embodiment, the expandable handrail made of the open-cell foam 15 having the structure shown in FIG. 7 is used. The open-cell foam 15 is formed by foaming a resin so as to form a large number of gaps 15a communicating with each other, and has sufficient elasticity. Other configurations are similar to those of the first embodiment.

Even when such an open-cell foam 15 is used, the feel of the expandable handrail 2 can be made uniform over the entire circumference. Moreover, since the same material is used all around, it can be easily manufactured. Further, since it is not partially repeatedly bent and stretched, a sufficient life can be secured. Furthermore, smooth movement along the handrail main body 1a can be realized. In addition, since it can be manufactured in a three-dimensional shape by the foaming process, the manufacturing cost can be reduced.

The stretchable handrail 21 is composed of a gap knitting structure 22 in which a strip is knitted so as to form a large number of gaps 22a. The gap knitting structure 22 is made up of the stretchable handrail 21.
Has a large number of rows 23 aligned with each other in the longitudinal direction and engaged with each other, and the rows of the rows 23 adjacent to each other are changed so that the telescopic handrail 21 is expanded and contracted in the longitudinal direction.

As a strip forming the gap knitting structure 22, for example, a steel wire having a diameter of about 1 to 2 mm is used.
Further, in the gap knitting structure 22, the strip body is not elastically deformed but is expanded and contracted due to the change in the overlap of the rows 23. Therefore, at the time of reduction, bulging due to the bending of the strip body in the outer diameter direction of the handrail main body 1a does not occur. Other configurations are
It is similar to the first embodiment.

Further, since it is not partially repeatedly bent and stretched, a sufficient life can be secured. Furthermore, smooth movement along the handrail main body 1a can be realized.

Further, since the stretchable handrail 21 constituted by the gap knitting structure 22 is used, the durability can be further improved and the stretchable handrail 21 can be firmly gripped.

In the third embodiment, the expandable handrail 21 is composed of only the gap knitting structure 22. However, the three-dimensional woven fabric shown in the first embodiment or the embodiment is formed on the outer peripheral surface of the gap knitting structure 22. The cover made of the open-cell foam 15 shown in the form 2 may be covered so that the cover and the gap knitting structure 22 are integrally expanded and contracted, and the feel of the expandable handrail can be improved.

Further, in the first to third embodiments, the drive section 12 having the conical rotating body 11 is shown. However, as long as the driven element is driven at different speeds depending on the position, the drive section according to another system is used. It may be. Furthermore, the present invention can be applied to both moving walkways and escalators.
