Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a variable speed type moving walkway capable of carrying passengers rapidly and flexibly even during a relatively long journey.

[0002]

2. Description of the Related Art Conventionally, various types of moving walkways have been proposed as variable-speed moving walkways, which move gently when passengers get on and off and move at high speed in the middle.

That is, as disclosed in Japanese Patent Publication No. 54-19676, a passenger can get on and off a curve to change a speed component gradually to obtain a variable speed moving walkway.
As shown in Japanese Patent No. 4 publication, belts having different speeds are arranged in a row to obtain a variable speed moving walkway.

[0004]

However, in the case of such a variable speed type moving sidewalk, there is a drawback that the mechanism is considerably complicated to drive while associating each pallet and each belt.

The present invention has been made in view of the above points, and an object of the present invention is to provide a variable speed moving walkway with a very simple drive mechanism.

[0006]

According to the present invention, a water tank in which the flow velocity of a fluid changes is provided along a conveying path, and a pallet is guided and guided by a guide rail according to the flow of the fluid in the water tank. In a moving walkway, a pallet is configured by alternately arranging a first pallet, which is a passenger's tread arranged above, and a second pallet, which is arranged below, and a tip of the first pallet. The rear end is bent toward the upper surface of the second pallet, and the back surface of the first pallet and the upper surface of the second pallet are slidably connected.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention uses the Bernoulli's theorem to make the structure of a water tank such that the velocity of a fluid is slow near the entrance / exit, the fastest in the middle, and gradually changes in the middle. The pallet is constructed so that the driving force can be properly obtained from this fluid.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 is a schematic view of a variable speed type moving walkway according to the present invention, FIG. 2 is a plan view of FIG. 1, FIG. 3 is an enlarged view of a main part of FIG. 1, and FIG. 4 is a view taken along line XX of FIG. is there.

In the figure, 1 is a board for loading, 2 is an exit plate, and 10 is a passenger pallet for carrying passengers. As shown in FIG. 3, the front end and the rear end are bent toward the upper surface of a lower pallet 20 described later. . Wheels 11 rotatably provided on both sides are guided along guide rails 12 (laid along the conveyance path), and pallet guides 13 and 13 'and a drive plate 14 are fixed on the back surface. The pallet guides 13 and 13 'each have an elongated hole 1
3a and 13'a. The drive plate 14 extends toward a water tank described later.

Numeral 20 is a lower pallet arranged below the riding pallets so as to close a gap between adjacent riding pallets 10, and a wheel 2 rotatably provided on both sides.
1 is a guide rail 22 (guide rail 1 along the transport path
2 is laid under 2), and the support members 23, 23 'such as L-shaped angles are provided on the upper surface.
Is fixed to the supporting member 23, and a guide roller 23a guided by the elongated hole 13a of the pallet guide 13 of the riding pallet 10 is rotatably provided (the supporting member 23 'is similarly provided with a guide roller 23'). Is rotatably provided), and the drive plate 24 is fixed to the back surface thereof as in the case of the passenger pallet 10. This drive plate 24
Similarly to the case of the drive plate 14, it also extends toward a water tank described later.

Reference numeral 30 is a water tank in which a fluid 31 such as water flows, and the low speed region A1 (that is, the vicinity of the entrance / exit) of the transport path is wide, the high speed region A3 (that is, the middle portion) is the narrowest, and the acceleration region A2. In the deceleration area A4, the width is gradually changed as shown in FIG. 40 is a balustrade.

Therefore, according to Bernoulli's theorem, the fluid flow is the slowest in the low speed range A1, the fastest in the high speed range A3, the flow gradually increases in the acceleration range A2, and the deceleration range A4.
Then the flow will gradually slow down.

Therefore, the riding pallet 10 and the lower pallet 20 which receive the force from the fluid in the water tank 30 by the drive plates 14 and 24 move together with the fluid in the respective positions, so that the riding pallet 10 and the lower pallet 10 existing in the low speed region A1. The pallet 20 is low speed, the riding pallet 10 and the lower pallet 20 existing in the high speed area A3 are high speed, and the riding pallet 10 and the lower pallet 20 existing in the acceleration area A2 are gradually increased in speed and exist in the deceleration area A4. The passenger pallet 10 and the lower pallet 20 are automatically moved so that the speed gradually decreases.

Here, at the transition of the acceleration range A2 and the deceleration range A4 or each speed range, the adjacent passenger pallet 10 is used.
And the lower pallet 20 move at different speeds, but the guide rollers 23a, 23'a of the lower pallet 20 are moved.
Does not cause any particular problem because it moves in the elongated holes 13a, 13'a of the pallet guides 13, 13 'of the riding pallet 10 to absorb the speed difference.

In this embodiment, the width of the water tank 30 is changed,
That is, we described an example where the width near the entrance / exit is wide, the width at the middle is narrow, and the width is gradually changed to change the velocity of the fluid in the middle, but the depth of the water tank is changed, that is, the depth near the entrance / exit is Can be configured so that the depth is deep, the intermediate portion has a small depth, and the depth is gradually changed in the middle, and the present invention is not limited to the embodiment.

The pallet driven by the fluid 31 is composed of two types of pallets arranged vertically, a pallet guide is provided on the back surface of the upper pallet, and a guide member is provided on the upper surface of the lower pallet. The guide and the guide member are configured to be capable of relative movement, but in short, since it is sufficient that the guide and the guide member are movably connected to each other along the conveyance path, they may be connected by, for example, a spring and are not limited to the embodiments. . Furthermore, it is not necessary that the upper pallet and the lower pallet are always connected alternately.

[0017]

As described above, according to the present invention, since the moving speed of the pallet can be freely changed with an extremely simple structure, an optimal variable speed type moving sidewalk can be freely selected according to the site condition. Can be obtained.
