[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a footpath of a moving walkway or an escalator (hereinafter referred to as a moving walkway, etc.), and particularly to a moving walkway that guides the footsteps by preventing abnormal settlement of the central portion of the adjacent footsteps. The present invention relates to a guide device.

[0002]

2. Description of the Related Art The main structure of a moving walkway is that a passenger is placed on a tread 1 which is connected endlessly along a traveling path as shown in FIG. 2, and a passenger's upper body is supported by a moving handrail 2 which moves in synchronization. While it is transported by personnel.

The surface of the tread is provided with a number of vertically long irregularities, and these irregularities are finely engaged with the comb plate 4 of the entrance / exit floor plate 3 at the end with slight gaps in the upper / lower, left / right directions. , It is a mechanism to protect the passengers' feet (to prevent the toes and foreign objects from being drawn into the gaps).

Up until now, the footboard has generally been about 1200 mm wide so that two passengers can ride side by side, but recently, a wide width of 1600 mm that can be used by three passengers side by side especially on a moving walkway. It is appearing.

Such a wide type is mainly installed for passengers carrying large luggage such as airports and stations.

In the case of this wide type tread, even if the tread 1 is supported and guided by the front wheel 1a and the rear wheel 1b in the front, rear, left and right directions as shown in FIG. In particular, at the entrance / exit, as the gap between the tread plate 1 and the comb plate 4 expands as shown in FIG. 4, the toes and foreign objects are drawn into the space, which is extremely dangerous.

Therefore, for example, Japanese Patent Laid-Open No. 1-117194
As shown in FIGS. 5 and 6, as shown in FIGS. 5 and 6, a supporting rail 5 is vertically arranged below the central portion of a comb plate 4, and a supporting frame 1c is provided on the back surface of the tread plate 1 so that the tread plate 1 can support the load. Even if it receives and bends to the lower side, the support frame 5 causes the support frame 1
A device has been proposed that prevents abnormal depression of the tread 1 by supporting and limiting c.

[0008]

In the actual use of such a device, when the tread 1 bends, the support rail 5 and the support frame 1c rub against each other, so that the surface of the support rail 5 should be protected from noise and vibration. It is not enough to use a slippery material, and the support frame 1c that is in contact with the support rail 5 needs to be made of a slippery material, and the support frame 1c different from the usual one must be attached to the back surface of the tread 1. There was a flaw. The present invention has been made in view of the above points, and an object of the present invention is to provide a device that can prevent abnormal depression of a tread without requiring any modification on the tread side.

[0009]

SUMMARY OF THE INVENTION According to the present invention, a wide tread that can be used by three passengers side by side is provided for a tread located at a doorway in a moving walkway that moves endlessly between a plurality of doorways. A rubber belt is movably arranged at a lower portion with a gap therebetween, and is supported and guided by the rubber belt when the tread plate sinks by a predetermined amount at the entrance / exit.

[0010]

With the above-described structure, the tread plate always moves at the entrance / exit in a state of being properly meshed with the comb plate.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an embodiment diagram showing a positional relationship between a tread and a guide device according to the present invention, and FIG. 7 is a front view of the tread,
In the figure, the same symbols as those in FIGS. 2 to 6 indicate the same components.

Reference numeral 11 denotes a reinforcing member provided at the center of the rear surface of the tread 1 regardless of the presence or absence of the guide device 20 according to the present invention.
21 Reinforcing member 11 of tread 1 meshed with comb plate 4
For example, a cylindrical roller 22 is rotatably provided on the lower truss side, and 22 is a cylindrical roller arranged at a distance in the traveling direction of the tread 1 so that a plurality of rollers 21 are interposed therebetween. It is rotatably provided on the side.

Reference numeral 23 is a hard rubber belt made of a material wound endlessly around the rollers 21 and 22, and is installed so as to normally maintain a gap δ with the reinforcing member 11 of the tread 1. This gap δ is a value at which the meshing amount δ ₁ between the comb plate 4 and the unevenness of the tread 1 is sufficient as shown in FIG. 8 even if the tread 1 bends and the reinforcing member 11 hits the rubber belt 23. The rollers 21 and 22 and the rubber belt 23 constitute the guide device 20 according to the present invention.

With such a structure, the deflection of the tread plate 1 increases due to the influence of the load and reaches a predetermined amount, and the reinforcing member 1
When 1 contacts the rubber belt 23 of the guide device 20, the rubber belt 23 starts to rotate smoothly in the moving direction of the tread 1 at the same speed. When the tread 1 is completely placed on the rubber belt 23, the tread 1 does not bend any more and the amount of depression of the tread 1 is restricted.

In the above description, the device for guiding the rubber belt 23 by the roller 21 is described, but a guide member 24 such as the guide shoe shown in FIG. 9 may be used. In this case, the material of the rubber belt 23 is different. It does not have to be a hard material.

[0016]

As described above, according to the present invention, even if a large load is applied to the tread, it is possible to extremely smoothly regulate the tread so that it does not bend more than a predetermined amount at the entrance / exit. It is extremely safe because passengers are not caught between the comb and tread. In addition, there is little risk of generating noise or vibration. Further, in the present invention, there is no need to modify or work on the tread side, so that it can be easily applied to an existing moving walkway or the like.
