Description

Description: TECHNICAL FIELD The present invention relates to a moving handrail guide device for a passenger conveyor such as an escalator and a traverter.

[Conventional technology]

3 and 4 show a moving handrail guide device for a passenger conveyor, which is shown as a conventional example in Japanese Utility Model Laid-Open No. 58-71066. In FIGS. 3 and 4, 1 is a balustrade panel which is arranged on both sides of a step (not shown) of the passenger conveyor, and is erected on the main frame 2 of the passenger conveyor along these transportation paths,
Reference numeral 3 is a balustrade frame fixed to the upper end of the balustrade panel 1. The balustrade frame 3 has a bottom plate 3b having a concave groove 3a at the center in the width direction on which the balustrade panel 1 is fitted and fixed via a packing 5 on the lower surface, both side plates 3c rising from both sides of the bottom plate 3b at right angles, and both sides. A handrail guide attachment portion 3d that projects at a right angle from the upper end of the plate 3c to the outer side opposite to the concave groove 3a is integrally formed. 4 is the above-mentioned mounting portion 3d of the balustrade frame 3
The pair of handrail guides are respectively held by the handrail guides 4, and the handrail guides 4 surround the upper end of the side plate 3c of the balustrade frame 3 and the outer periphery of the mounting portion 3d and are elastically held by these parts, and the side plate 3c is inserted. The opening 4a is formed only in the portion, and the opening 4a is provided on the side of the balustrade panel 1 on the lower side 4c of the oblong oval. The opening 4a is formed along the longitudinal direction of the balustrade panel 1. . Reference numeral 6 denotes a moving handrail that is driven in synchronization with the steps, and the moving handrail 6 is formed in a substantially C-shaped cross section with an opening on the lower surface.
Both sides of the inner peripheral surface of the handrail guide body 4 are detachably fitted and slidably supported.

In the moving handrail guide apparatus configured as described above, in order to attach the handrail guide body 4 to the balustrade frame 3, as shown in FIG. 5, the opening 4a side is close to the upper side 4b in the free state. Handrail guide 4 with lower side 4c inclined to
Is tilted so that the opening 4a becomes higher, the opening 4a is applied to the tip of the mounting portion 3d of the balustrade frame 3, and the handrail guide 4 is made parallel to the mounting portion 3d of the balustrade frame 3 while mounting the mounting portion 3d. As shown in FIG. 4, it is fixed to the balustrade frame 3 by elastically holding the mounting portion 3d and the upper end of the side plate 3c from the outer periphery.

[Problems to be solved by the invention]

In the conventional moving handrail guide device for a passenger conveyor as described above, when the handrail guide body 4 is fitted into the balustrade frame 3, as shown in FIG. 5, the handrails are provided above and below the tip of the attachment part 3d of the balustrade frame 3. The inner peripheral surfaces of the upper and lower sides 4b, 4c of the guide body 4 come into contact with each other at points A and B, and the lower end of the handrail guide body 4 on the opening 4a side comes into contact with the center of the upper surface of the mounting portion 3d in the width direction at point C. So
Hard to fit. Therefore, utilizing the fact that the handrail guide 4 is made of a flexible plastic such as nylon, while elastically deforming the upper side 4b so as to expand the opening 4a, as shown by the chain line in FIG. It is fitted to the balustrade frame 3. Therefore, it is necessary to apply a large force to the handrail guide body 4 to deform the handrail guide body 4, which requires a great deal of labor,
In addition, the handrail guide body 4 is given an excessive force so that the handrail guide body 4
There was a problem that cracks were generated on the inner peripheral surface of the.

The present invention has been made to solve the above problems, so that the handrail guide body can be easily attached to the balustrade frame with a small force, and the handrail guide body is not cracked at the time of attachment. It is an object of the present invention to provide a moving handrail guide device for a passenger conveyor.

[Means for solving problems]

In the moving handrail guide device for a passenger conveyor according to the present invention, a groove facing the upper surface of the handrail guide body mounting portion of the balustrade frame is formed along the longitudinal direction on the inner peripheral surface of the upper side portion of the handrail guide body.

[Action]

In the moving handrail guide device according to the present invention, since the groove is formed on the inner peripheral surface of the upper side portion of the handrail guide body, when the handrail guide body is attached to the balustrade frame, the handrail guide body is fitted into the attachment portion of the balustrade frame and The lower end of the handrail guide on the opening side abuts at a position near the side plate on the upper surface of the mounting part, and due to the formation of a groove, the handrail guide can be easily elastically deformed with a small force, resulting in unnecessary force. Absent.

〔Example〕

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

In FIGS. 1 and 2, the same reference numerals as those in FIGS. 4 and 5 indicate corresponding portions, and 4d is a groove formed on the inner peripheral surface of the upper side portion 4b of the handrail guide 4 excluding both widthwise side portions. Is. The groove 4d has a substantially trapezoidal cross section in which both hypotenuses are curved in an arc shape, and is provided over the entire length in the longitudinal direction of the handrail guide body 4.
The structure of this embodiment other than that described above is the same as the conventional structure shown in FIGS. 3 and 4.

In the moving handrail guide device of the embodiment configured as described above, when the handrail guide body 4 is fitted to the balustrade frame 3, the
As shown in the figure, the balustrade frame 3 is fitted deeply until the bottom of 4d provided on the upper side 4b of the handrail guide 4 abuts on the upper end of the attachment 3d, and the position near the side plate 3c on the upper surface of the attachment 3d. The lower part of the handrail guide body 4 on the side of the opening 4a comes into contact with. Further, since the upper side portion 4b of the handrail guide body 4 is thin due to the formation of the groove 4d, it is easily elastically deformed. When the handrail guide body 4 is pushed further with a force from the state shown in FIG. 2 by these, the upper side portion 4b of the handrail guide body 4 is elastically deformed smoothly with a small force so as to expand the opening 4a. As shown in, the handrail guide 4 surrounds the outer periphery of the mounting portion 3d of the balustrade frame 3 and the upper end of the side plate 3c, and the upper side portion 4b is parallel to the mounting portion 3d. In this state, the handrail guide 4 has the above-mentioned mounting portion.
It is held and fixed to the upper ends of 3d and the side plate 3c by elastic restoring force. Therefore, the handrail guide body 4 can be easily attached to the balustrade frame 3 with a small force.

In this embodiment, the groove 4d is provided on the upper side portion 4b of the handrail guide body 4, so that the handrail guide body 4 cannot be pushed and spread during mounting, so that the inner peripheral surface of the handrail guide body 4 does not crack. , Quality is improved.

In addition, in the above embodiment, the groove 4d having a substantially trapezoidal cross section is formed on the inner peripheral surface of the upper side portion 4b of the handrail guide 4, but the present invention can appropriately change the cross sectional shape of the groove, for example, an arc shape. it can.

〔The invention's effect〕

As described above, according to the present invention, the handrail guide body can be easily attached to the balustrade frame with a small force by forming the groove on the inner peripheral surface of the upper side portion of the handrail guide body. Since no unnecessary force is applied at the time of mounting, it is possible to prevent the handrail guide body from cracking and improve the quality.
