[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor device such as an escalator or an electric road which can be easily installed on stairs, slopes or flat terrain of stations and public facilities.

[0002]

2. Description of the Related Art Conventionally, in order to reduce the installation space of a passenger conveyor, for example, an escalator device, in particular, to reduce the height of a support frame, for example, Japanese Patent Publication No. 48-19996 and Japanese Patent Laid-Open Publication No. A passenger conveyor device described in Japanese Patent No. 32577 is proposed.

[0003]

The above-mentioned conventional passenger conveyor apparatus has a configuration in which a tread plate is reversed and circulated along the outer periphery of a large-diameter guide wheel in a machine room at both longitudinal ends of a support frame. As a result, the height of the machine room of the support frame could not be reduced, which hindered the reduction of the installation space of the passenger conveyor device.

[0004] It is an object of the present invention to provide a new passenger conveyor device capable of reducing the installation space by reducing the height of a machine room of a support frame.

Another object of the present invention is to provide a passenger conveyor device capable of smoothly moving a tread plate between a forward path and a return path.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a passenger provided with a plurality of treads that are connected endlessly and circulate in a support frame installed over upper and lower floors. In the conveyor device, the tread plate is configured to circulate between the outward path and the return path with the tread surface facing upward.

[0007] With the above configuration, the treads moving on the outward route (return route side) enter the return route side (forward route side) with the tread surface facing upward, and move on the return route (forward route side) in the opposite direction. Therefore, the height dimension of the support frame is sufficient if there is enough space to move the tread plate between the forward side and the return side with almost the same posture, and it is not necessary to install a large-diameter guide wheel that turns the tread plate 180 degrees. unnecessary. As a result, it is possible to reduce the height of the support frame in the moving direction reversing portion of the tread plate, thereby reducing the installation space.

Further, since a mechanism is provided between the forward path and the return path to transfer the tread plate with the tread surface facing upward, the tread can be smoothly moved between the forward path and the return path.

A pair of upper sprockets 5 are mounted on the upper ends of both sides of the support frame 41A in the longitudinal direction.
Further, a pair of lower sprockets 4 are mounted on the lower ends.

The upper end and the lower end of the side frame 41A in the longitudinal direction are in a substantially horizontal state, and the middle part is in an inclined state along the stairs 6 at an inclination angle.

A pair of right and left drive chains 7 are wound around the upper sprocket 5 and the lower sprocket 4, and the return side of the drive chain 7 is set inside the bottom frame 41B or the upper surface of the bottom frame 41B. Go around.

A tread plate 8 is provided between a pair of right and left drive chains 7.
A base end 8A is rotatably connected, and a horizontal transition roller 8B is mounted on a free end of the tread plate 8 via a shaft 8S.

The horizontal shift rollers 8B are provided on both side frames 41.
The traveling is guided by a guide rail 13 provided at A. This horizontal shift roller 8B and guide rail 1
3 constitutes the guide means G.

The guide rail 13 is provided along the forward slanting portion of the tread plate 8 and extends from the lower end in the longitudinal direction of the side frame 41A to the intermediate slanting portion so as to be spaced apart from the drive chain 7 and the bottom. The guide rail 13 is located closer to the drive chain 7 at the upper end of the side frame 41A in the longitudinal direction. Also, this guide rail 13
It is provided discontinuously with a return rail (not shown).

In FIG. 2, a pin protruding laterally from a base end 8A provided on the upper floor 3 side of the tread plate 8 is rotatably connected to a connecting portion of the drive chain 7. The horizontal shift roller 8B is mounted on a shaft 8S protruding on both sides of the free end on the lower floor 2 side of the tread plate 8 to guide the guide rail.
The roll 13 has a groove on its upper surface for guiding the movement of the horizontal shift roller 8B. 7A and 7B are guide plates of the drive chain 7.

In operation of the escalator device having the above structure, the upper sprocket 5 is driven at an appropriate speed by a traveling drive source 9 such as a motor and a control device (not shown). By selecting forward or reverse rotation of the traveling drive source 9, the drive chain 7 can be moved vertically.

In ascending operation, the tread plate 8 whose base end 8A is pivotally supported by the drive chain 7 is driven by the drive chain.
By moving the shaft 7 in the direction of the arrow P, it rises while maintaining a horizontal state, and when descending, the tread plate 8 whose base end 8A is supported by the drive chain 7 is driven by the drive chain.
By moving the button 7 in the direction of the arrow Q, it descends while maintaining a horizontal state.

By the way, in the case where the tread plate 8 is circulated between the forward path and the return path, reversing the moving direction of the step plate 8 between the forward path and the return path will be described with reference to FIG.

When the rear end side of the traveling direction of the tread plate 8 in the forward path is connected to the drive chain 7, the tread plate 8 passes between a pair of sprockets located at the rear end side of the traveling direction. By doing so, the tread 8 can be circulated between the outward route and the return route without any trouble. However, desirably, the configuration in which the tread plate 8 passes between a pair of sprockets to which the traveling drive source 9 is connected can be a more reasonable configuration.

In FIG. 4, by providing a portion where the guide rail 13 does not exist in front of the upper sprocket 5, the horizontal shift roller 8B can be returned from the outgoing side without returning the tread plate 8 to the 180 ° reverse rotation. It is structured to drop to the side. Further, a space is formed between the pair of left and right upper sprockets 5 and 5 and the lower sprockets 4 and 4, and a tread plate 8 having a base end 8 A mounted on a drive chain 7 in the space.
The transfer mechanism is configured to freely reverse the moving direction while keeping the tread surface facing upward. Reference numeral 19 denotes a counter shaft for distributing the power of the traveling drive source 9 to the pair of left and right upper sprockets 5.
