Abstract

PURPOSE:To prevent an accident of drawing a shoe of a passenger, and improve the design and strength by providing a diagonal surface part combined with a proper flat part at the peaks on both side parts of a step surface. CONSTITUTION:When an escalator is running up, if a passenger is on a step surface 2 with a toe 12T of a vinyl shoe 12 in contact with a skirt guard 11, the guard 11 is moving in the direction of A relatively to a step 1. The toe 12T therefore gets into a V-letter shaped space formed by a diagonal surface part 4S and the guard 11 by the friction force to the guard 11. The toe 12T then continues to be pushed into the space to receive a force in the direction of B, where because there is the diagonal surface part 4S on the forward end side of the arrow B, a reaction force R generates in the diagonal surface part 4S. This reaction force R becomes larger than the friction force of the guard 11 to move the toe 12T to generate a slip between the toe 12T and the guard 11 at last, so the toe 12T will not get into a small gap (g). The toe 12T of the vinyl shoe 12 of the passenger is thus kept at the diagonal surface part 4S.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a step for a passenger conveyor and a guard used therein.

(Prior Art) Generally, the steps of a passenger conveyor, such as an escalator, include a tread having a large number of cleats along the direction of travel, and a riser extending downward from one end of the tread in the direction of travel. , These are connected and rotated in an endless manner, and are arranged so that both sides of the tread and riser face the skirt guard that covers the inner lower side of the erected parapet with a gap ( Utility Model Publication No. 55-67068).

[Problem to be solved by the invention]

When operating an escalator equipped with steps configured as described above, a relative movement occurs between the steps and the skirt guard. Therefore, if a passenger steps on the step with part of his footwear in contact with the skirt guard, the step Footwear may be pulled into the gap between the skirt guard and the skirt guard. Such accidents occur in the gaps between the treads of the steps and the skirt guards when the escalator is in upward operation, in other words, when the steps are moving in an upward direction.

In order to prevent shoes, etc. from being drawn into the gap between the step and the skirt guard, a caution sign is installed on one step to alert passengers to the area where they should place their feet on the step, and to prevent footwear from being drawn into the gap between the step and the skirt guard. However, this only served as a warning and did not provide any concrete improvement measures.

SUMMARY OF THE INVENTION An object of the present invention is to provide a step for a passenger conveyor, and a caution body used for the step in the exposed area, which can prevent the accident of a passenger's footwear being drawn into the gap between the step and the skirt guard.

[Means to solve the problem]

In order to achieve the above object, the present invention forms a sloped portion on the side of the tread facing the skirt guard in a direction that approaches the skirt guard downward from the top.

The width of the top of the crosspiece on the side of the tread is
While making the width larger than the width of the top of the crosspiece at the center of the tread, provide a flat part with approximately the same width as the top width of the crosspiece at the center of the tread on the anti-skirt guard side. The above sloped portion was formed within the width of the area other than the flat portion.

Further, it is preferable that the slope portion is provided in advance on a caution body provided on both sides of the tread surface of the step, and the caution body is attached to both sides of the tread surface.

In addition, the slope portion is preferably formed discontinuously along the direction of travel.

[Effect]

Passenger conveyors such as escalators and electric guideways equipped with steps configured in this manner have a sloped section that acts to keep the footwear there when the passenger's footwear attempts to be drawn into the gap between the step and the skirt guard. By making the sloped part of the step tread discontinuous, the non-slope part adjacent to the sloped part can prevent footwear from being pulled into the gap. do.

On the other hand, the width of the tops of the crosspieces on both sides of the tread is made larger than the width of the tops of the crosspieces at the center of the tread, and the width of the tops of the crosspieces at the center of the tread is made larger than the width of the tops of the crosspieces at the center of the tread. Since we provided a flat part with a width that is approximately the same as the width of the top, the crosspieces on both sides (
Even if a sloped portion is formed on the surface, the tip will not become sharp, improving both safety and design and strength.

Also, by forming the sloped part to be careful.

Formation of the slope portion becomes easier.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. The step 1 of the escalator includes a tread 2 on which a passenger rides, and a riser 5 extending downward from one end of the tread 2 in the traveling direction of the S-force 1 node. It is connected in a shape and rotates. The tread 2 of this step 1 includes a tread part 3 made of aluminum alloy or stainless thin steel plate and provided with a large number of cleats 3C along the traveling direction, and a tread part 3 formed of a synthetic resin etc. and provided with a plurality of cleats 3C along the traveling direction. It is composed of a caution body 4 provided with 4C. The caution bodies 4 are detachably attached to both sides of the tread portion 3, and are of a different color from the tread portion 3 and have an attention-grabbing effect, for example, yellowish color.

On the other hand, on both sides of the step 1 having such a configuration, handrails 6 are erected over almost the entire length of the escalator. This balustrade 6 includes a balustrade panel 7 that stands upright with its lower part fixed to a fixing member (not shown), a guide frame 8 attached to the upper part of this balustrade panel 7, and a step 1 guided by this guide frame 8. The lower part of the inner side (step 1 side) of these handrails 6 is covered with an inner deck 10, and the lower part of the inner side is covered with a skirt guard 11 connected to the inner deck 10. It's covered. Both sides of the step 1 and the skirt guard 11 face each other with a gap g.

In addition, among the cleats 4C of the caution body 4 in step 1, on the side of the cleat 4B facing the skirt guard 11, there is a slope portion 4S in the direction approaching the skirt guard 11 with respect to the side where a gap g exists from the top 4T. has been established. This slope portion 4S is a linear slope with a certain angle. Taking as an example the cleat 4B having the linear sloped portion, the operation of preventing the passenger from pulling the vinyl shoe 12 into the gap g will be described below with reference to FIG.

Now, when the escalator is moving upward and a passenger is riding on the tread 2 with the toe 12T of the vinyl shoe 12 in contact with the skirt guard 11, the skirt guard 1
1 is moving in the direction of arrow A in FIG. 1 relative to step 1, so the toe 1 of the vinyl shoe 12
2T is due to the frictional force with the skirt guard 11, as shown in FIG.
Enter the character-shaped space. Then, within this space, the toe 12
T is continuously pushed in and receives a force in the direction of arrow B, but since there is a sloped portion 4S on the tip side of arrow B, this sloped portion 4S
A drag force R is generated. This drag force R becomes larger than the frictional force of the skirt guard 11 that moves the toe 12T, and eventually slippage occurs between the toe 12T and the skirt guard 11, so the toe 12T does not enter the narrow gap g. Therefore, the toe 12T of the passenger's vinyl shoes 12 is
Remains in S.

At this time, if the passenger notices something abnormal and tries to withdraw his or her feet, there is no need to pull the vinyl shoe 12 directly upward along the skirt guard 11, but just to pull it diagonally upward along the slope θ of the slope portion 4S. It can be pulled in easily.

On the other hand, in the case where there is no slope part 4S and there is only the gap g, if the vinyl shoe 12 enters the gap g even a little, there is no retention area against the crowd and no resistance is generated, so the gap gradually increases. I am drawn deep into g. Even if an attempt is made to pull out the retracted vinyl shoe 12, the user has to pull it directly upward along the skirt guard 11, which is extremely troublesome.

By the way, the 7-shaped space formed by the slope portion 4S is provided within the width dimension of the top portion 4T of the cleat 4B that constitutes the crosspieces on both sides of the tread, as shown in FIG. However, as shown in FIG.
(Wx>W2.), and the remaining portion after forming the sloped portion 4S is provided with a flat portion 4SS having approximately the same dimension as the width Wz (width W3 is Wz4Ws).

This flat part 4SS has a sharp top part of the cleat 4B due to the provision of the slope part 4S, and has a safety effect of preventing the tip from causing harm to passengers, and the width of the top part is uniform over the entire tread surface. It not only has the design effect of looking good, but also the strength effect of preventing it from becoming tapered and easily breaking.

Further, the slope portion 4S may be provided continuously over most of the entire length as shown in FIG. 5, or the slope portion 12S may be provided discontinuously on the cleat 12C of the caution zone 12 as shown in FIG. Good too. In this case, the remaining convex portion 13 has the effect of pushing up the tip of the shoe and preventing it from further intruding into the gap g.

In this way, the vinyl shoes 1 that were easily drawn between the skirt guard 11 and the tread 2 when the escalator was in ascending operation.
2 and prevent personal injury.

Incidentally, the slope portions 4S provided on both sides of the tread surface 2 in step 1 are formed on a caution body 4 having a separate configuration from the tread surface portion 3, but there is no caution body 4 having a separate configuration, and the entire surface of the tread surface 2 is In the step where the tread portion 3 is made of aluminum alloy or the like, the sloped portion may be processed at the same time as the tread portion 3 is formed, or the sloped portion may be formed after molding. but,
Currently, it is common practice to attach a separate caution body 4 when assembling the step, so it is better to provide a caution body 4 with a sloped portion 4S formed in advance and attach it to both sides of the tread when assembling the step. Forming the slope portion 4S is easy. Furthermore, the present invention can be implemented by simply replacing the caution body 4 for stored items.

Incidentally, the slope portion 4S is the vinyl shoe 1 pushed into the V-shaped space.
In order to make it easier to pull out the parts 2 and the like, it is desirable that the surface is as smooth as the other parts of the caution body 4. this is,
For example, the caution body 4 can be easily obtained by integrally molding a synthetic resin.

Incidentally, although all of the above explanations have been made regarding escalator steps, the present configuration can also be applied as is to electric road steps.

〔Effect of the invention〕

According to the present invention, sloped parts are provided on the tops of both sides of the step tread in combination with suitable flat parts, so that the footwear of the passenger that is about to be drawn into the gap with the skirt guard is retained there. This prevents accidents caused by footwear being pulled in, and is advantageous in terms of design and strength.

Further, by making the slope portion discontinuous and providing a convex portion between adjacent slope portions to form an engaging portion, it is possible to separate the footwear staying on the slope portion from the skirt guard.

Further, by forming the slope portions on the caution bodies attached to both sides of the step tread, the slope portions can be easily formed, and the slope portions can be formed in advance when manufacturing the step. In addition, by replacing the caution body, it can be easily applied to passenger conveyors currently in use.
