Abstract

PURPOSE:To flexibly correspond to the floor height of a building and to simplify installation of a man conveyor by arranging each of large and small diametrical pulleys on both end parts in the longitudinal direction of an endless belt formed in a sector form and connecting an elastic body to the small diametrical pulley as well as connecting a motor to the large diametrical pulley. CONSTITUTION:The endless belt 1 of a half spiral type man conveyor is formed in a sector form with width W required for conveying a passenger and having each of specified radiuses R1, R2 on both inside and outside. Thereafter, a large diametrical pulley 2 is arranged on one end on the inside of the endless belt 1, and by connecting an elastic body 4 to its axis 3, tensile force is given to the endless belt 1. Conversely, by arranging a small diametrical pulley 5 to the other end on the inside of the endless belt 1, a motor 7 is connected to its axis 6. In this way, the half spiral type man conveyor is constituted independently drivable. Additionally, by continuously arranging a plural number of the half spiral type man conveyors of the same configuration as required in accordance with the floor height of a building, a man conveyor of a spiral locus can be constructed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a man conveyer having a spiral locus, and more particularly to a man conveyer suitable for flexibly responding to the height of a building floor.

[0002]

2. Description of the Related Art Various man conveyors having a spiral locus have been proposed. For example, as disclosed in Japanese Examined Patent Publication No. 4-28626, a plurality of steps having a horizontal plane and a chain or the like form the lowest floor to the top floor. It is known that all of them are continuously connected to each other and are driven to rotate by one unit.

[0003]

In the prior art, a rail for rolling a roller of a step having a horizontal surface along a spiral locus is laid along the spiral locus, and each step is chained from the bottom floor. It had to be continuously connected to the top floor, and there were problems in space efficiency, installation, and maintenance work as the drive capacity increased.

It is an object of the present invention to provide a flexible response to the height of a building and to improve the safety of passengers, and to reduce the amount of installation and maintenance work.

[0005]

The above object is to construct a tread surface with a long endless belt formed with a constant width, and to arrange a pair of large-diameter pulley and small-diameter pulley at both longitudinal ends of the endless belt. Then, one large-diameter pulley is driven by a motor, and the other large-diameter pulley is configured to apply tension to the endless belt by an elastic body, and the small-diameter pulley reverses the tread side of the endless belt. This is achieved by arranging a plurality of devices on a tread running path of a required length (height) in a continuous manner.

Further, the above-mentioned object is to make the speed of the handrails at the upper end of the balustrade arranged on both sides of the tread forming a spiral locus different between the inner circumference side and the outer circumference side of the tread surface. It is achieved by matching the speed of the handrail to the peripheral speeds of the outer and outer sides.

[0007]

As described above, by sequentially arranging the devices having the endless belt and its drive system as one unit, a tread running path having a spiral locus of a required length and height is formed. For this reason,
The capacity of the driving machine is subdivided as compared with a continuous single device as in the conventional example, and naturally the capacity dispersion and the space occupied by it are also small, which is convenient. Further, since the installation and maintenance of this device can be performed for each device, the weight and the inspection range are limited, and the labor can be saved.

On the other hand, the endless belt is driven by a pair of large-diameter pulleys at both ends thereof. A small-diameter pulley provided in the tread side reversing portion near the large-diameter pulley is an endless belt. The radius of reversal can be reduced, and inevitably the gap between adjacent endless belts and the recess formed by reversal can be reduced to prevent the passenger's foot passing there from being caught. Can exert the effect of. In addition, by providing a vertical step on the tread surface between adjacent endless belts and the tread surface, there is a function of transmitting to the foot a gap harmful to safety, which is present in the connection part between the two, and calls attention. Can also contribute to improving safety.

Further, among the handrails arranged on both sides of the tread, those on the inner side of the tread are set at an approximate peripheral speed of the inner circumference of the tread, and those at the outer circumference of the tread are set at an approximate peripheral speed of the outer circumference of the tread. As a result, the passengers on the inside of the tread and those on the outside each have a foot speed that is substantially the same as the hand speed,
A stable posture is secured and its safety is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

1 and 2 of the drawings showing this embodiment.
The handrail and balustrade are not shown in the figure.
A device of this kind will be illustrated in FIGS.

In FIG. 1, assuming that the inner cylinder is the pillar of the building in which the spiral conveyor is arranged, the inner side of the endless belt is a spiral line along a cylinder having a radius R1 which is approximately equal to the radius of the pillar of the building. . On the other hand, the outside of the endless band is a spiral line along a cylinder having a radius R2, which is the radius R1 plus the width of the endless band. The endless belt 1 of the semi-helical passenger conveyor of the present invention shown in FIG. 2 has a width W necessary for carrying passengers and an inner radius R.
1, a fan-shaped outer radius is set to R2, the whole is made endless, the pulley 2 is arranged at one end on the inner side, and the shaft 3 thereof is given tension by the elastic body 4 to the endless belt 1, Obi 1
A pulley 5 is arranged at the other inner end of, and a shaft 7 of the pulley 5 is wound by a motor 7 to be driven. Since a force toward the center o is generated in the endless belt 1, the flanges 2a and 5a are provided inside the pulleys 2 and 5, respectively. Figure 3 shows an endless belt 1, a balustrade 8, and a handrail 9.
FIG. 3 is a side view of the endless belt 1, showing a state in which the passenger rides on the upper surface of the endless belt 1. The sliding members 10 support the weight of the passenger and reduce the running resistance of the endless belt 1 over the entire area. And a roller 11 are provided.

Here, a small-diameter roller 12 is provided on the upper side in the vicinity of the large-diameter pulleys 2 and 5 and at the reversal part of the endless belt 1, and the small-diameter roller 12 drives the endless belt 1. While following the rotation, they play a role of reducing the radius of rotation of the endless belt 1 and reducing the gap g between them.
In addition, the endless belts 1 adjacent to each other have a step g in the up-down direction, which gives a strange feeling to the soles of passengers passing through the gap g.
It is configured to call attention to safety such as notifying the existence of.

Among the handrails 9 shown in FIG. 4, the speed of the handrail 9a on the inner peripheral side X of the tread 1 is approximately the same as the peripheral speed of the inner peripheral tread 1, and the handrail 9b on the outer peripheral Y of the tread 1b.
Is a different speed that is similar to the peripheral speed of the outer tread 1 and
Safety consideration is made so that both the inside passengers and the outside passengers on the tread 1 have the same speed at their feet and hands.

According to this embodiment, the semi-helical man conveyer can be independently driven, and the required number of semi-helical man conveyers of the same shape are continuously arranged according to the height of the building floor. As a result, it is possible to form a man-conveyor with a spiral locus, and it will be possible to deal with infinite building floor heights if it is extreme theory.
