BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a balustrade of a passenger conveyor provided on both sides of a step of the passenger conveyor such as an escalator or a moving walkway and supporting and guiding a moving handrail.

[0002]

2. Description of the Related Art FIG. 3 is a side view showing a conventional escalator shown in, for example, Japanese Utility Model Laid-Open No. 63-77986 and Japanese Patent Laid-Open No. 64-2993. In the figure,
1 is a main frame (truss), 2 are a plurality of steps which are provided in the main frame 1 and are circularly moved in an endlessly connected state, 3 are tempered glass standing on both sides of the step 2 of the main frame 1. The glass panels 3 are made of glass, and a plurality of the glass panels 3 are arranged along the moving direction of step 2. Four
Is a balustrade frame attached to the outer peripheral portion of the glass panel 3, and 5 is a rubber moving handrail that is wound around the balustrade frame 4 and moves in synchronization with the movement of step 2.

Next, FIG. 4 is a sectional view taken along the line IV-IV of FIG. In the figure, reference numeral 6 denotes a shatterproof film attached to the outer surface (counter-step side) of the glass panel 3, and the shatterproof film 6 is, for example, a transparent polyester film coated with an adhesive. Are used. Reference numeral 7 denotes an upper packing attached to the upper end of the glass panel 3, and the balustrade frame 4 is attached from above the upper packing 7. Reference numeral 8 is a balustrade having a glass panel 3, a balustrade frame 4, a shatterproof film 6 and an upper packing 7.

9 is a skirt guard attached to the main frame 1 so as to face the side of step 2, and 10 is a balustrade 8.
The outer plate which is attached to the main frame 1 on the outer side of the skirt guard 9 in parallel with the skirt guard 9, 11 is an inner deck provided between the skirt guard 9 and the balustrade 8, and 12 is between the outer plate 10 and the balustrade 8. An outer deck, 13 provided on the lower deck is a lower packing for sealing between the inner and outer decks 11 and 12 and the balustrade 8.

In the conventional escalator as described above,
Since the shatterproof film 6 is attached to the glass panel 3, even if the glass panel 3 is destroyed by an impact or the like, the glass pieces of the glass panel 3 are prevented from scattering around. 5 is a cross-sectional view taken along the line VV of FIG. 3, but at the end portion of the glass panel 3 in the step movement direction, the shatterproof film 6 is cut along the chamfered portion of the end portion. Has been done. Further, there is a gap 14 of about 3 to 5 mm at the joint (tree mouth) between the glass panels 3 adjacent to each other.

[0006]

In the conventional balustrade 8 of the escalator configured as described above, since the end portion of the shatterproof film 6 is located on the surface of the glass panel 3 on the opposite step side, The cleaning liquid or the like is likely to adhere to the end portions of the shatterproof film 6, which deteriorates the adhesive agent of the shatterproof film 6 and causes the shatterproof film 6 to gradually peel off from the end portions. In addition, the anti-scattering film 6 may be peeled off due to deterioration of the adhesive with time or direct external force to the anti-scattering film 6.

As described above, when the anti-scattering film 6 is peeled off, when the glass panel 3 is broken, the anti-scattering effect of the exfoliated part cannot be obtained, and there is a problem that sufficient safety cannot be maintained. Further, especially on a moving sidewalk, there are many passages outside the glass panel 3, and there is a high risk that a pedestrian's luggage or the like collides with the joint of the glass panel 3. The shatterproof film 6 also acts as a cushioning material against the impact from the outside of the glass panel 3 as described above. On the other hand, the glass panel 3 becomes weak. Moreover, in the glass panel 3, a part of the damage spreads to the whole, so that there is a problem that the entire glass panel 3 is easily broken due to the partial peeling of the shatterproof film 6. Further, when the anti-scattering film 6 is peeled off, there is a problem in that this portion is rolled up and dust is attached, which makes the appearance unfavorable.

The present invention has been made to solve the above-mentioned problems, and a passenger capable of preventing peeling of the shatterproof film and maintaining safety and appearance for a long period of time. The purpose is to get the balustrade of the conveyor.

[0009]

The balustrade of the passenger conveyor according to the invention of claim 1 is one in which a shatterproof film is attached in a state of being wound up to the end face in the step movement direction of the glass panel.

In the balustrade of the passenger conveyor according to the second aspect of the present invention, the caulking material is filled in the gap between the glass panels adjacent to each other so as to cover the end portion of the shatterproof film.

[0011]

In the present invention, by preventing peeling of the shatterproof film, safety and appearance are maintained for a long period of time.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. Example 1. FIG. 1 is a sectional view of a main part of a balustrade of an escalator according to an embodiment of the present invention. In the figure, the shatterproof film 6 is attached to the outer surface (counter-step side) of the glass panel 3 as in the conventional case, but the end portion thereof is wound up to the end surface of the glass panel 3 in the step movement direction. There is. That is, the mouth of the glass panel 3 is covered with the shatterproof film 6. Other parts are the same as those in FIGS. 3 and 4.

In this way, by winding the anti-scattering film 6 to the end surface of the glass panel 3, the end of the anti-scattering film 6 is hidden in the gap 14, so that the cleaning liquid adheres to the end of the anti-scattering film 6. In addition, it becomes difficult to apply a direct external force and peeling is prevented. Even if the adhesive is deteriorated, the scattering prevention film 6 extends to the outer surface of the glass panel 3 by the amount of extending the end portion as compared with the conventional one.
It will take time for the peeling off. Therefore, the scattering prevention effect can be maintained for a long time, and the cushioning effect against the impact from the outside of the glass panel 3 can also be maintained. As a result, safety can be maintained for a long period of time, and good appearance can be maintained for a long period of time.

Example 2. Next, FIG. 2 is a cross-sectional view of the main part of the balustrade of the escalator according to an embodiment of the invention of claim 2. In the figure, 21 is a caulking material filled in the gaps 14 between the glass panels 3 adjacent to each other, and the ends of the shatterproof film 6 are covered with the caulking material 21. Further, in order to easily cover the end of the shatterproof film 6 with the caulking material 21, the shatterproof film 6 is attached up to the chamfered part of the end of the glass panel 3.

When such caulking material 21 is used,
Peeling from the end of the shatterproof film 6 is more reliably prevented, and is strong against impacts on the end of the glass panel 3, and safety and appearance are maintained for a long period of time.

In each of the above embodiments, the case where the transparent shatterproof film 6 is used is shown, but a colored film or a patterned film may be used, and the same effects as those of each of the above embodiments can be obtained. Further, although the escalator is shown in each of the above embodiments, the present invention can be applied to a balustrade of a moving sidewalk.

[0017]

As described above, in the balustrade of the passenger conveyor according to the invention of claim 1, since the anti-scattering film is rolled up and attached to the end face of the glass panel in the step movement direction, the anti-scattering film is prevented from peeling off. Therefore, it is possible to prevent the glass panel from being damaged by an impact from the outside, and it is possible to more reliably prevent the glass pieces from scattering when the glass panel is broken, and it is possible to maintain safety for a long period of time. In addition, it has the effect of maintaining good appearance for a long period of time.

In the balustrade of the passenger conveyor according to the invention of claim 2, the gap between the glass panels adjacent to each other is filled with caulking material, and the caulking material covers the end of the shatterproof film. The same effects as the effects of the invention of claim 1 are obtained.
