Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to an I
li! The present invention relates to an escalator, and particularly to the structure of a conveyance path mainly consisting of steps.

[Prior art]

First, 1. According to Figure 2, 1 for example
A curved escalator similar to that shown in the '559 publication is described.

In the figure, (1) is a conveyance path, and this conveyance path Il+ has a constant inclination 1 interval A that is inclined in the vertical direction as the middle, and both the upper and lower sides of this section A (Ill VC inclination angle changes, and the lower part Upper and lower horizontal movement sections are formed through A and A, and the outbound and return routes are connected at both ends of these sections.
The horizontal projection surface is formed into a curved semicircle. (2) is a large number of fan-shaped steps that move along the conveyance path ill; (3) is a parapet erected on the main frame (41 along the longitudinal direction of the conveyance path (1); (5) is a clothesline (3); )
This is a moving handrail that is supported by and driven in synchronization with the step (21).

Prior art curved escalators as described above.

It was constructed so that the fan-shaped step was guided by a guide rail with a constant radius of curvature. However, in a 9-curve escalator, the inclination angles of the outer τ111 guide rail and the inner 1 guide rail are different, so if the radius of curvature of the guide rail is constant as described above, the angular velocity of the inner and outer circumference of the fan-shaped step is equalized. Therefore, it is necessary to increase the distance between the step axes that connect the adjacent steps to the chain at parts where the inclination angle changes, such as the upper and lower parts A and A of the conveyance path. The problem is that the structure becomes complicated and the cost increases.

[Summary of the invention]

This invention provides a curved edge escalator as described above,
The guide rail is formed to have a constant radius of curvature in the constant slope section in the middle of the conveyance path, the radius of curvature increases as the slope angle decreases in the upper and lower curved sections, and the radius of curvature is constant in the upper and lower horizontal movement sections. The object of the present invention is to solve the above-mentioned problems by forming the escalator to have a constant radius of curvature that is larger than the radius of curvature of the inclined section, and to provide a curved escalator that is easy to construct and inexpensive.

Next, the principle of the curved escalator of this invention is shown in FIG.
This will be explained with reference to FIG.

O, A7. At the part where it deviates from B7, the one fan-shaped step is reversed as the chain meshes with the chain gear, and returns by the return path just below the guide rail on the outbound side of the conveyance path in the vertical direction.

The radius of curvature of the inner guide rail in the horizontal projection plane gradually becomes smaller as it goes from the horizontal movement section side to the constant slope section (1111VC) in the upper part of Fflt1.

FIG. 4 is a principle diagram showing the step formation of the present invention, and shows the dimensional relationship when the step axes of adjacent steps are directly connected by a roller chain or link.

When traveling in the upper and lower horizontal movement sections, there is no difference in level between the steps that touch each other momentarily, and there is no overlap between them.

The step plane is represented by a figure ABCD, and when each point is connected with a straight line, it becomes a trapezoid ABCD. The inclination angle at the portion yc corresponding to the outer circumference and inner circumference of each step is θ1L.

02', the exposed surface of the step in the intermediate constant slope section will be AB/σD, and the overlapped part with the 1 inch step will be BB'C'C. The exposed surfaces of each adjacent step are polygons AB'EF...DC'GH... which are sequentially arranged on a plane as trapezoids AB'C/Dft.
Outside this polygon, the radius of the circumscribed circle connecting the river points A B'E F... is R1'(θ1'), and the inner point DC'G

...(2) Note 9. Although the above 1f formulas from formula (31) to formula (41) are omitted, formula (4) is an approximate value approximated with an accuracy of about 0.01%.

Similarly, the radius of the outer guide rail for guiding the steps of the present invention is expressed as the radius of the inner guide rail.

That is, the inclination angle θ1 of the outer periphery and the inner periphery. When θ2.

Radius of curvature R1 (θ1), R2 (θ2) centered at 0'
The steps are guided along a spiral guide rail that forms an arc in the horizontal projection plane in the intermediate constant slope section.

When guiding a step party in the lower horizontal movement section, it is preferable that the VC be guided on a guide rail that forms an arc with curvature radii R1 and R2 centered at 0. In addition, since the angle of inclination is constant in the middle slope section, the radius of curvature of the guide rail is also a constant value, and the angle of inclination changes. Accordingly, the above formula +51

This is outside the scope of the actual design. It must be set so that the inner chain becomes the inner chain, and the actual design cannot be carried out unless the width dimension W between the outer and inner chains of the connecting tool is considerably increased. This is because the width dimension W can be designed to any size as long as the human dimension a of the incorporated connector is not equal to the chain pitch p.

Note that, although not shown in the drawings, the driving force is taken out from a chain gear provided on the reversal part of the driving side of the moving handrail, thereby eliminating the need for noise from the variable speed moving handrail.

Therefore, the gaps between the side edges of the moving step (2) and the inner and outer skirt guards (c) and C141 are approximately constant, thereby improving the safety of the passengers.

Note that the configuration of the above embodiment other than the above is the first and second configurations.
Since it is similar to the curved escalator shown in the figure, the explanation will be omitted.

It also includes a conveyance path whose horizontal projection plane is curved, and a large number of fan-shaped steps that move along this conveyance path, and the step shafts provided on these steps are connected to the outer chain 8111 and the inner chain, respectively.

A kite rail that guides the step shaft is formed to have a constant radius of curvature in the constant off-shore slope section, and the above-mentioned above.

In the lower case 1≦, the radius of curvature is increased by 1 due to the decrease in the angle of use, and furthermore, in the horizontal movement section, the radius of curvature is formed at a constant radius larger than the radius of curvature of the oblique section around 1 square. , and a skirt guard is installed parallel to the guide rail. Therefore, if this invention is oblique! Escalator II', each step axis of the m-shaped steps can be connected to the outside and inside (1111 chains VcIir), and the relationship dimensions between 1111 touching steps can be easily regulated with fV14L structure. , the gap between the moving step and the skirt guard will be constant,
It has the effect of being safer and being able to reduce manufacturing costs.
