Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable-speed passenger conveyor, and more particularly to a variable-speed passenger conveyor suitable for transporting wheelchairs, carts, and the like.

[0002]

2. Description of the Related Art In a passenger conveyor that assists passengers in moving in the horizontal direction, if the transportation takes a long distance, it takes a long time to move the passenger conveyor. Many variable speed types that make the speed relatively slow have been devised.

This variable-speed passenger conveyor is roughly classified into a system in which belt conveyors and rollers having different speeds are changed, a system in which a pallet on which a passenger is mounted is slid sideways so that a diagonal speed is variable, and a pallet interval is expanded and contracted. There is a method of realizing a variable speed by using the method. The transfer method is, for example,
In Japanese Patent Application Laid-Open No. 6-15693, the skid method is described in, for example,
No. 0 discloses this.

As a method of expanding and contracting a pallet interval, for example, Japanese Patent Publication No. 46-7057 and Japanese Patent Application Laid-Open No. 57-203479 disclose a method of driving a pallet by engaging a gear or a chain at a constant speed portion. Is disclosed. In addition, JP
No. 4,436,686 discloses a construction in which the front and rear pallets are connected using a link mechanism, and the pallet in the acceleration / deceleration portion is driven in conjunction with the traveling of the pallet driven by the constant speed portion.

[0005]

The mechanism using the link mechanism disclosed in Japanese Patent Application Laid-Open No. 50-43686 does not require a transfer, and is suitable for a user who is currently using the vehicle, such as changing the direction of movement when riding due to skidding. There is no need to take extra action,
In order to carry a wheelchair, a cart, or the like, it is necessary to increase the length of the pallet. In order to safely transport a wheelchair or a cart, the length of the pallet for transporting people is required to be two to three times longer, so that the height of the drive mechanism is also two to three times higher. A great deal of work is required for embedding this mechanism.

Further, in order to transport a wheelchair or the like even in the skidding method, it is necessary to increase the length of the pallet. In the transfer method, there is a difference in speed between the pallets or belts to be changed, so that the transfer itself is difficult.

It is an object of the present invention to provide a variable-speed passenger conveyor capable of transporting a wheelchair, a cart or the like by a speed increasing method using a link mechanism.

[0008]

In order to achieve the above object, a plurality of pallets are provided in a passenger conveyor which transports passengers by pallets and changes the speed by expanding and contracting a pallet distance between an entrance end and an intermediate portion. A link means for transmitting power and extending for variable speed, a fixing means for fixing the link means and a plurality of pallets, and a link means for each pallet length in a direction perpendicular to the extension direction. It has connecting means for rotatably connecting and guide rail means for guiding extension of the link means.

[0009]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram illustrating a schematic configuration according to an embodiment of the present invention. FIG. 1A is a plan view of a variable-speed passenger conveyor as viewed from above. FIG. 1 (b)
It is the figure which looked at the variable-speed passenger conveyor from the lower part. The pallets 1a, 1b, 1c are connected to each other without any gap, and secure a sufficient area for use in a wheelchair or the like. Link mechanism 2
Are connected to the central pallet 1b by the fixing part 3.
The link mechanism 2 is connected by a connecting portion 4 that can rotate in a direction perpendicular to the extension direction for each unit that fits within the length of the pallet when contracted. The link of the link mechanism 2 is expanded and contracted by the guide rail 5. At the entrance with the landing plate 6, the link mechanism 2 contracts until it just fits under the pallet,
In the middle part, the pallets 1a, 1b, 1c are expanded and the speed is increased.

Reference numerals 7a, 7b and 7c denote handrails,
In this embodiment, 7a is driven at the same speed as the pallet 1 near the entrance and exit, 7c is driven at the same speed as the pallet 1 which has been increased in the middle, and 7b is driven at the intermediate speed.

FIGS. 2A and 2B are explanatory views of the most contracted state near the entrance and exit, where FIG. 2A is a view as seen from below, and FIG.
Is a side view. FIG. 5 shows a pallet 1 in the most contracted state in the vicinity of the entrance / exit and a view seen from below the link mechanism. When the link mechanism 2 is contracted, each pallet 1
It fits in the lower part of a, 1b, and 1c, and the connection part 4 is comprised so that it may be located in the boundary between each pallet. The connection part 4
Since each of the pallets can be rotated in the vertical direction, each pallet can be rotated in the vertical direction for each pallet, and the radius at the time of inversion can be reduced. 8 is a guide roller.

FIG. 3 is an explanatory view of a state where the pallet 1 is extended at the intermediate portion, and shows the pallet 1 and the link mechanism 2 which are extended at the intermediate portion. The pallet 1 is connected to the link mechanism 2 by a fixed portion 3 at the center pallet 1b, and the link mechanism stored under the pallets 1a, 1b, 1c expands around this, and in the case of this embodiment, , About 4 times speed increase.

FIG. 4 is an explanatory diagram for explaining the movement when the pallet is reversed.

FIG. 5 is a three-sided view of the link. (A) is a link 2-1 connected to the connection unit 4, and (b) is another link 2-2.

FIG. 6 shows an example in which the link mechanism 2 is doubled. The description will be made in a state where the intermediate portion is extended. Two sets of link mechanisms 2 are prepared for the pallet and the first link mechanism 2a and the second link mechanism 2b, and are fixed to the pallet 1b by the first fixing portion 3a and the second fixing portion 3b. The link mechanisms 2a and 2b extend and contract by being guided by the first guide rail 5a and the second guide rail 5b, respectively.

According to the present embodiment, the load per set of the link mechanism 2 can be divided, so that the link can be reduced in weight and a longer-distance variable-speed passenger conveyor can be realized.

[0018]

According to the present invention, in a variable-speed passenger conveyor using a link mechanism for connecting the front and rear pallets, a function sufficient for transporting a wheelchair, a cart, and the like is provided by the height and construction of the variable-speed passenger conveyor. This has the effect of making it possible to realize this without increasing the depth of the hole required.

According to the present invention, there is an effect that the acceleration / deceleration portion of the variable-speed passenger conveyor can be easily configured.
