[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving handrail of a passenger conveyor such as a moving walkway or an escalator, and more particularly,
The present invention relates to a moving handrail of a variable-speed passenger conveyor in which a moving speed of a tread is changed between an entrance and an exit.

[0002]

2. Description of the Related Art Conventionally, for example, as described in Japanese Patent Laid-Open No. 7-40689, a first moving handrail member that moves at the same speed as the moving speed of a tread near the entrance and exit, A plurality of second moving handrail members that move at the same speed as the moving speed of the tread in the middle portion between the entrance and the exit are provided on one side, and the first moving handrail member and the second moving handrail are provided. There has been proposed a moving handrail for a variable-speed passenger conveyor in which members are respectively driven by a drive device so as to correspond to the moving speed of a tread.

Further, for example, Japanese Patent Laid-Open No. 2001-32278
As described in Japanese Patent Laid-Open No. 8 (1994), the first acceleration from the first speed to the second speed while moving from one end to the other end.
Synchronized handrails, a constant-speed handrail that moves at a second speed, and a second speed to a third speed while moving from one end to the other.
And a second synchronizing handrail portion that is decelerated to a speed of, wherein the first synchronizing handrail portion and the second synchronizing handrail portion are
There has also been proposed a moving handrail for a variable-speed passenger conveyor, which is composed of a series of link members that can expand and contract in the moving direction and means for controlling the expansion and contraction of the link members, and is provided on both sides of the row of treads.

[0004]

By the way, in the above-mentioned prior art, in which a plurality of the first moving handrail members and the second moving handrail members are provided on one side, at least three moving handrails are provided on one side. Since it is necessary to arrange the passenger conveyors in a row, the width of the entire device of the passenger conveyor is widened, the installation space is limited, and a drive device is required for each of the first moving handrail member and the second moving handrail member. Since the structure is complicated, there is a problem that manufacturing cost increases and maintainability deteriorates.

Further, in the case of the first synchronous handrail part, the constant-speed handrail part and the second synchronous handrail part, the moving handrail is divided into three parts, and the moving handrail is connected to the handrail part and the handrail part. Not only is it troublesome to grab the grip, but since the first synchronizing handrail part and the second synchronizing handrail part are each composed of a series of link members and control means, the structure becomes complicated and the manufacturing cost increases. In addition, there is a problem that maintainability is deteriorated.

The present invention has been made in view of the above-mentioned circumstances in the prior art, and its purpose is to have a relatively simple structure, and also to grab the moving handrail from when the passenger gets on the tread to get off. It is to provide a moving handrail of a variable speed passenger conveyor that can be used without any use.

[0007]

In order to achieve the above object, the present invention has a plurality of endlessly connected treads and a balustrade standing upright to the side of these treads. In a moving handrail of a variable-speed passenger conveyor in which the moving speed of the tread is changed between the first and second exits, a first moving handrail that moves at a constant speed on the balustrade, and a first moving handrail
And a plurality of second moving handrails slidably fitted to the moving handrail.

In the present invention thus constructed, when the passenger does not use the passenger conveyor, the first moving handrail moves on the balustrade at a predetermined constant speed, and the second moving handrail also moves to the first moving handrail. And moves at the above-mentioned constant speed. Next, when the passenger gets on the tread from the entrance and grabs the second moving handrail, the tread that the passenger got in gradually accelerates, and the second moving handrail gripped by the passenger is placed on the first moving handrail. The second moving handrail moves in synchronization with the tread by sliding. After that, when the passengers on the tread approach the exit, and the tread gradually decelerates, the second moving handrail also decelerates in synchronization with the tread. As a result, the structure is relatively simple, and the passengers can use it without having to grab the moving handrail from getting on the tread to getting off.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a moving handrail of a variable speed passenger conveyor according to the present invention will be described below with reference to the drawings.

FIG. 1 is a side view of a variable speed passenger conveyor having a moving handrail according to an embodiment of the present invention, and FIG.
3 is an enlarged perspective view showing the moving handrail of FIG. 3, FIG. 3 is a sectional view taken along line AA of the moving handrail shown in FIG. 1, and FIG. 4 is a sectional view taken along line BB of the moving handrail shown in FIG.

The variable-speed passenger conveyor shown in FIG. 1 is endlessly connected, and has a plurality of steps 2 provided with a tread 2a and a roller 2b, which are scaffolds for the passenger 1, and are erected on both sides of these steps 2. And a driving means (not shown) capable of changing the speed of the step 2 between the entrance 5 and the exit 6. The moving handrail guide 4 is extended above the balustrade 3. .

The plurality of steps 2 are respectively connected to the shafts of rollers 2C which are connected to a drive chain (not shown) and move along rails (not shown) which guide the rollers 2b and 2C. For example, a plurality of steps 2 may be passenger 1 from bottom to top.
When the vehicle is driven in the carrying direction, that is, in the ascending direction, the step 2 moves from the lower entrance 5 to the upper exit 6, and descends inside the passenger conveyor (not shown) for continuous endless operation. At that time, the step 2 moves at a speed of 20 m / min near the entrance 5 and the exit 6, accelerates at the start of the intermediate portion between the entrance 5 and the exit 6, moves at 40 m / min, and decelerates at the end. Since the passenger 1 can safely get on and off at the entrance 5 and the exit 6 at low speed operation, the passenger 1 can be efficiently transported at a high speed at an intermediate portion between the entrance 5 and the exit 6. It is possible.

The moving handrail of this embodiment is movably fitted to the moving handrail guide 4 at the upper end of the balustrade 3.
It is composed of a first moving handrail 7 that moves along the moving handrail guide 4 at a constant speed and a plurality of second moving handrails 8 slidably fitted to the first moving handrail 7. The first moving handrail 7 has the same size as the normal moving handrail, and the second moving handrail 8 is slightly larger than the normal moving handrail. The first moving handrail 7 and the second moving handrail 8 are made of an elastic material such as rubber, and are configured to follow the curved portion of the moving handrail guide 4 in a curved manner. As shown in FIGS. 3 and 4, a sliding means, for example, a sliding member 9 made of a material that reduces the coefficient of friction is provided on the downward surface of the center of the second moving handrail 8.
Is provided, and this sliding member 9 is used as the first moving handrail 7
The second moving handrail 8 moves smoothly with respect to the first moving handrail 7 by contacting the upper surface of the second moving handrail 7.

The first moving handrail 7 is driven in conjunction with the power of the step 2 and exits from an exit 10 located in the vicinity of the lower entrance 5 at a constant speed of 20 m / min to an upper exit 6. It enters into the located entrance 11 and descends inside the passenger conveyor (not shown) so as to continuously move endlessly. Further, the first moving handrail 7 is curved and formed in a substantially C-shape, and is slidably fitted to the moving handrail guide 8. A pair of engaging grooves 12 formed along the longitudinal direction (that is, the moving direction of the first moving handrail 7) are provided on both sides of the first moving handrail 7, respectively. A plurality of right-angled triangular projections 13 on the upward surface
Are formed. Each of these protrusions 13
It includes an inclined portion 13a that gradually rises along the moving direction of the first moving handrail 7 and a step portion 13b that descends from the apex of the inclined surface 12a.

The total length of all the second moving handrails 8 is shorter than that of the first moving handrail 7, and each of the second moving handrails 8 can slide on the first moving handrail 7. The number and the length of the second moving handrails 8 are set so that a predetermined gap is formed between the second moving handrails 8 adjacent to each other in a state where the passenger 1 is riding on all the steps 2 from below to above without any gap. It is desirable to set the height.

Further, the second moving handrail 8 is curved and formed in a substantially C-shape, and a pair of engaging portions 14 facing each other are provided at both ends, and each engaging portion 14 is a first engaging portion. It is adapted to engage with the engaging groove 12 of the moving handrail 7. As shown in FIG. 4, a plurality of right-angled triangular protrusions 15 that engage with the protrusions 13 of the first moving handrail 7 are formed on the downward surface of the engaging portion 14.

As a result, the projection 13 of the first moving handrail 7 and the projection 15 of the second moving handrail 8 are engaged with each other, and the second moving handrail 8 is moved in the moving direction (that is, by the arrow C in FIG. 4). When an external force (in the direction shown) is applied, the protrusion 15 of the second moving handrail 8 slides on the inclined portion 13a of the protrusion 13 of the first moving handrail 7, so that the first moving handrail 7 On the other hand, the second moving handrail 8 can be smoothly moved in the direction indicated by the arrow C in FIG. Conversely, the second moving handrail 8
When an external force in the direction opposite to the moving direction (that is, the direction indicated by the arrow D in FIG. 4) is applied to the stepped portion 13b of the protrusion 13 of the first moving handrail 7, the protrusion 1 of the second moving handrail 8 is applied.
Since 5 is locked, the second moving handrail 8 does not move with respect to the first moving handrail 7 in the direction indicated by the arrow D in FIG.

In this embodiment, when the passenger 1 does not use the passenger conveyor, the first moving handrail 7 has the balustrade 3
While moving up at a speed of 20 m / min, the second moving handrail 8 also follows the first moving handrail 7 and moves at a speed of 20 m / min. Next, when the passenger 1 uses the passenger conveyor, the passenger 1 gets on the step 2 from the lower entrance 5 and grasps the second moving handrail 8 and stands still in that state. At this time, the step 2 on which the passenger 1 boarded gradually accelerated at the intermediate portion between the entrance 5 and the exit 6 and 40 minutes per minute.
The second gripped by the passenger 1 as it moves at a speed of m
The second handrail 8 slides on and follows the first handrail 7 so that the second handrail 8 moves in synchronization with the step 2 at a speed of 40 m / min. After that, when the passenger 1 on the step 2 approaches the exit 6, the vehicle 1 gradually decelerates to the exit 6
In the vicinity, it moves at 20m / min. At this time, the second moving handrail 8 gripped by the passenger 1 also decelerates in synchronization with the step 2 and moves at 20 m / min. Then, when the passenger 1 releases his / her hand from the second moving handrail 8, the second moving handrail 8 follows the first moving handrail 7 in a state of being engaged with the first moving handrail 7 and moves at 20 m / min. Keep moving at speed.

For example, even when a plurality of second moving handrails 8 are arranged in the vicinity of the doorway 5 in succession, the second moving handrail 8 connected upward from the second moving handrail 8 grasped by the passenger 1 is provided. The group also moves smoothly with respect to the first moving handrail 7.

Further, when the passenger 1 who gets on the step 2 tries to catch the second moving handrail 8 and there is no second moving handrail 8, first, after grasping the first moving handrail 7, the step It suffices to grab the second moving handrail 8 moving toward the passenger 1 as the vehicle 2 accelerates. That is,
The first moving handrail 7 functions not only as a guide for the second moving handrail 8 but also as a handrail gripped by the passenger 1. Therefore, in any case, the passenger 1 loses the handrail and falls. do not do.

In the present embodiment having such a configuration, the second
The moving handrail 8 of the first moving handrail 7 follows the passenger 1.
Since it slides on, the passenger 1 can use the second moving handrail 8 without having to grab the second handrail 8 after getting on the step 2 and getting off, and the moving speed of the step 2 changes between the entrance 5 and the exit 6. Safe passengers even with variable speed passenger conveyors 1
Can guide you.

Further, in this embodiment, the first moving handrail 7 that moves along the moving handrail guide 4 at a constant speed, and a plurality of slidably fitted to the first moving handrail 7. Since it is composed of the individual second moving handrails 8, it has a relatively simple structure and requires a small installation space.

Further, in this embodiment, when the passenger 1 does not use the passenger conveyor, the projection 15 of the second moving handrail 8 engages with the projection 13 of the first moving handrail 7. , The second moving handrail 8 is the first moving handrail 7
Then, when the passenger 1 gets on the step 2 and grips the second moving handrail 8, the second moving handrail 8 slides on and follows the first moving handrail 7. The second moving handrail 8 can be driven without additional power.

In this embodiment, as a sliding means provided on the contact surface of at least one of the first moving handrail 7 and the second moving handrail 8, a friction coefficient is applied to the downward surface of the second moving handrail 8. Although the sliding member 9 made of a reducing material is attached, the same effect can be obtained by disposing rolling elements such as balls and rollers on the downward surface of the second moving handrail 8. Further, sliding means may be provided on the upward surface of the first moving handrail 7.

Further, in this embodiment, the projection 13 of the first moving handrail 7 and the projection 1 of the second moving handrail 8 are provided.
5, the engaging means is provided on the contact surface of each of the moving handrails 7 and 8 and can restrain the moving direction of the second moving handrail 8 with respect to the first moving handrail 7 in one direction. .
