Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to spiral type passenger conveyors such as escalators and electric roads, and more particularly to multi-bend type handrails.

Two types of conventional passenger conveyors, escalators that go up and down at an inclination angle of 30 degrees and electric roads with a gentle inclination, have become popular in many areas by taking advantage of their respective characteristics. However, in recent years, people have grown tired of the linear transportation functions of these two models, and there has been a strong demand for T-type passenger conveyors if they can provide passengers with a wider field of view.

The spiral type has the advantage of providing a panoramic view of the interior of a shopping store, allowing a wide view of the products on display.

As shown in Fig. 1, this spiral type passenger conveyor has a tread plate 1 which is arranged in an endless manner and extends upward and downward while bending laterally to travel in an arcuate manner. A parapet 5 having a lower deck 2, an upper deck 3, and a side plate 4 is arranged in an arched shape like the tread 1 to form a transportation route for this passenger conveyor.

The footboard 1 repeatedly travels through a convex curve section A (curvature Rs) and a concave curve section B (curvature height), and moves from the standard floor to the target +1. This guide mechanism for the treadle 1 is expected to be commercialized by using the bending principle found in general transportation conveyors.

However, there are many unresolved problems regarding the flexibility of the handrail 6 at the upper end of the handrail 5 and its guide mechanism, which should rotate at the same speed and in the same direction as the footboard 1. That is, the synchronized running of the handrail 6 and the treadle 1 is essential for the allantoic membrane of the passengers, and technical issues regarding the reeds, lowering, and bending have become a bottleneck for commercialization. This problem includes a significant reduction in the lifespan of the handrail 6 due to bending, and a solution to this problem is desired.

An object of the present invention is to provide a rail with excellent flexibility and a guide mechanism therefor.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

1 and 2 show a spiral type passenger conveyor having a convex curved section A and a concave curved section B. FIG. This rail 6 has an inner side 3a and an outer side 3b of the upper deck 3.

It runs along a guide path 7 formed by the L-portion opening 4a of the side plate 4. Here, the handrail 6 is
The surface portion 6a, which occupies most of the area, forms a circular shape that is generally considered to have the lowest bending resistance, and the lower surface portion thereof has a convex portion 6b for connecting with the adjustable chino 8.

And this handrail 6 and swivel chino 8 are screw 9
Furthermore, a plurality of guide rails 11 are fixed to the inner wall of the upper deck 3 on the upper, lower and side sides of the holder 10 fixed to the upper side of the adjustable chino 8. It is arranged in an endless manner. Furthermore, a drive wheel 12 is provided at key points on the guide path 7 to obtain power from a drive source (not shown) and transmit it to the adjustable chino 8, and the handrail 6 is rotated by the power of this drive wheel 12.

Here, the configurations of the adjustable chino 8 and the handrail 6 will be described. Both are bent through the lines shown in FIGS. 3 and 4. In other words, the adjustable cheno 8 is generally of a side-bent type called a side box (5IDEBOW) low 2 chain, and has two types: normal vertical bending (curvature 3 in Figure 3) and lateral bending. Bending (Fig. 4 Curvature 几4
). In this case, the bending in the upward, downward and lateral directions is shown in FIG. a.1 This is done by being guided by a guide rail 10 that forms a curved path in the guide path 7 that is the same as the curved shape of the handrail 5, and finally causes the handrail 6 to travel in a predetermined curve.

By adopting the drive system using the swivel chain 8, the handrail 6 has less bending resistance, and is significantly less slippery and elongated than the friction drive drive method used in conventional passenger conveyors. Improved.

According to the present invention, it is possible to improve the life and running function of the 71st rail of a spiral type passenger conveyor.
