BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings.

FIGS. 1 (a) and 1 (b) are a horizontal cross-sectional view and a side view of a shaft of a bearing body showing a first embodiment of a moving handrail guide device of the present invention.

The moving handrail guide device shown in FIG. 1A is similar to the above-mentioned conventional moving handrail guide device in that it has a handrail belt 11.
A steel plate 12 having a predetermined thickness is embedded therein, and the handrail belt 11 is provided on the guide rail 13.
The guide rail 13, the bearing ball 14, the bearing wheel 15, and the bearing body 16 constitute a guide portion.

Inside the guide rail 13, a bearing body 16 composed of a bearing ball 14 and a bearing wheel 15 is provided.
A small groove is provided on the outer periphery of 5. Then, a circular annular elastic body 19 made of, for example, nitrile rubber is fitted into the small groove.

The bearing body 16 is a link support body 110.
The bearing shaft 18 is mounted on the guide rail 13 and is arranged along the curve of the guide rail 13. Bearing wheel 1 of the other pair of bearing bodies 16
A circular ring-shaped elastic body 19 is also fitted to 5 and is likewise attached to the shaft 18.

Since the thickness of the circular annular elastic body 19 is larger than the depth of the small groove provided in the bearing wheel 15, the elastic body 19 projects from the wheel surface. Therefore, the inner surface of the handrail belt 11 traveling on the curved portion does not directly contact the wheel 15 itself, and the elastic body 19 contacts the handrail belt 11 and the elastic body 19
By itself buffering the collision of the handrail belt with the bearing body,
The handrail belt runs stably.

On the other hand, the handrail belt 11 has the bearing body 16
At the place where it is in strong contact with
9 is crushed and comes into contact with the handrail belt 11 in a wide range, and similarly runs stably.

By the way, in the embodiment of the present invention shown in FIG. 1A, one elastic body 19 is fitted in one small groove formed on the outer periphery of the bearing wheel 15. However, a plurality of elastic bodies may be provided. FIG. 1C shows a sectional view of an embodiment in which two elastic bodies 19, 19 are provided on the outer periphery of the bearing wheel 16.

When a plurality of circular annular elastic bodies 19 are fitted to one bearing wheel in this manner, the contact portion with the inner surface of the handrail belt is increased and the vertical loads received by the elastic bodies are distributed to the elastic bodies 19. Can be made. This makes the collision of the handrail belt more gentle,
Wear of the elastic body 19 can be suppressed. There is also an advantage that shock contact with the handrail belt is buffered, abrasion of the inner surface of the handrail belt is suppressed, and maintenance frequency of the handrail belt is reduced.

According to the embodiment of the present invention in which the above-mentioned bearing wheel is fitted with the ring-shaped elastic body, the handrail belt travels while making stable contact with the bearing body, so that collision noise is reduced and noise is reduced. You can run.

The weight applied to the bearing body when the handrail belt travels on the bearing body varies depending on the traveling condition, but is very large. Therefore, the circular ring-shaped elastic body 1 is used.
The fitting force of the expansion / contraction force of 9 itself may be insufficient. In such a case, the elastic body 19 is fixed to the small groove of the bearing wheel 15 using an adhesive. By fixing the elastic body 19 with the adhesive in this way, it is possible to prevent the elastic body 19 from peeling from the small groove, and prevent the elastic body 19 from falling off.

According to this embodiment, the stress acting on the elastic body 19 changes due to a change in traveling conditions such as an increase or decrease in the number of passengers and traveling speed. It is possible to travel with more stable contact without being affected by changes in conditions.

The moving handrail guide device, in which an annular elastic body fitted to a bearing wheel is fixed with an adhesive, prevents the elastic body from peeling off, and enables traveling while maintaining a more stable contact regardless of traveling conditions. The running noise can be reduced.

Next, a second embodiment of the present invention will be described. FIG. 2A is a transverse cross-sectional view of the bearing body according to the present embodiment taken along the axis thereof, and FIG. 2B is a side view thereof.

In this embodiment, as shown in FIG. 2A, a urethane rubber type elastic body 29 is laminated on the entire outer circumference of the bearing wheel 25 of the bearing body 26 and vulcanized. By this vulcanization treatment, the bearing wheel surface is rich in elasticity and absorbs impact force.
Becomes The bearing body 26 is also formed by laminating the urethane rubber elastic body 29 on the outer periphery of the bearing wheel 25 of the other pair of bearing bodies, and is connected by the link support body 210 together with the vulcanized bearing body. Install on both sides of the bearing shaft 28.

In the second embodiment, the entire width of the bearing wheel 25 is covered and laminated with an elastic body 29 made of, for example, a urethane rubber material having a relatively large elastic coefficient, and the lamination and the adhesion to the wheel surface are strengthened. Vulcanization treatment is applied to By vulcanizing the wide elastic body 29, the inner surface of the handrail belt 21 traveling in the curved portion and the wide range of the elastic body 29 formed over the entire width of the wheel 25 are stably brought into contact with each other. This stable contact cushions the collision of the handrail belt 21, suppresses the collision noise, and the handrail belt 21 travels stably without noise.

According to the second embodiment, the impact can be absorbed by the elastic body, and the collision noise can be further suppressed. Furthermore, when the elastic body is fixed to the bearing wheel by vulcanization, a strong and long-lived moving handrail guide device can be provided.

Next, a third embodiment of the present invention will be described.

FIG. 3 is a transverse cross-sectional view of the bearing body along the axis according to this embodiment. In this embodiment shown in FIG. 3, the bearing balls 34 and the bearing wheels 35.
An elastic body 39 is inserted between a bearing shaft roller 37 to which a bearing body 36 configured by and a guide rail 33 on which the bearing shaft roller 37 is mounted are inserted.
The inserted elastic body 39 cushions the impact of the traveling handrail belt 31 colliding with the bearing body 36.

In this third embodiment, the handrail belt 31
While running, the handrail belt 31 and the bearing wheel 35
Even if a collision occurs, the impact is absorbed by the inserted elastic body 39. Therefore, the handrail belt 31 and the bearing body 36 are in gradual contact with each other, and the vehicle runs without noise such as collision noise. Further, when the handrail belt 31 and the bearing body 36 are in strong contact with each other, the elastic body 39 is compressed and deformed, the bearing body 36 is shifted to the guide rail 33 side, and the contact is also maintained. No noise is generated.

In the third embodiment, the contact between the handrail belt and the bearing body is kept stable to reduce the collision noise of the handrail belt, and also functions as a damper for installing the bearing shaft roller 37, so that the handrail belt travels. There is also an effect of preventing the mechanical vibration of the rotation of the bearing body 36 associated with the above from leaking to the guide rail.

In addition to being installed and manufactured for the above purpose at the time of manufacturing, when the above-mentioned collision noise or running noise is remarkably generated in the existing man conveyor device, it is not necessary to replace parts and the plate-shaped elastic body is not required. It can also be repaired or improved by inserting.

Next, a fourth embodiment of the present invention will be described. FIG. 4 is a transverse cross-sectional view of the bearing body along the axis according to the fourth embodiment.

In this embodiment, the bearing 47 provided on the shaft 48 of the bearing body 46 is held by the guide rail 43 by the spring 49, and the bearing body 46 is pushed out in the direction of the handrail belt 41 and held.

Therefore, the bearing wheel 46 is
It is extruded onto the inner surface of the handrail belt 41 and is in light contact with or separated from the handrail belt by the repulsive force of the spring 49. Further, when the handrail belt 41 travels, the contact force is increased due to the rigidity of the steel plate 42 inside the belt, and when the tension pulling the handrail belt 41 inside the curved portion is applied, the tension of the handrail belt 41 and the fishing This spring 49 is shortened so that the handrail belt 41 and the bearing body 4 are fitted together.
Maintain contact with 6.

In the fourth embodiment, since the shaft 48 of the bearing body 46 expands and contracts the spring 49, the tension of the handrail belt and the repulsive force of the spring are balanced so as to balance even when the handrail belt 41 travels. Handrail belt 4
The impact of collision No. 1 is absorbed, and no collision noise or the like is generated while the handrail belt 41 is running.

Since the passenger conveyor equipped with the moving body handrail guide device according to the present invention produces very little noise,
It can also be installed in a place with low noise such as a hospital.

[0037]

As described above, in the moving handrail guide device according to the present invention, since the bearing wheel is brought into contact with the handrail belt by the elastic body or the spring, the running of the handrail belt is stabilized. The collision noise with the bearing body can be reduced.
