Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor such as an escalator or an electric road, and more particularly to a balustrade structure which has an improved fixing structure for an inner deck cover portion and is excellent in assembling and designing.

[0002]

2. Description of the Related Art Passenger conveyors such as escalator
Used mainly in shopping centers such as department stores and supermarkets, in a wide range of fields such as hotels, museums, airports, and railway stations, it has become established as a safe and effective means of transportation with continuous and mass transportation. .

By the way, in the conventionally known passenger conveyors, the steps and the moving handrails generally endlessly travel back and forth between one of the entrances and exits of the other, and both sides of the above steps. The balustrade stands upright to guide and support the outward path of the moving handrail. The balustrade comprises a balustrade panel, an inner deck cover, an outer deck cover, a skirt guard, etc., and constitutes a design portion of the entire passenger conveyor.

The design members of the balustrade described above, especially the inner deck cover formed on the surface, are members that determine the design value of the passenger conveyor, and the aesthetics of the surface and the superiority or inferiority of the combination accuracy are extremely important. Yes, unsightly gaps and steps at each seam on the inner deck cover are most disliked.

In order to solve these problems, a conventional technique for fixing the inner deck cover is disclosed in Japanese Patent Laid-Open No. 10-1725.
As known from Japanese Patent No. 4, the inner deck cover is fixed only by the biasing force of a leaf spring or a biasing member.

Further, recently, there has been a patent application characterized in that a step suppressing piece is provided at the upper end coupling portion of the inner deck cover and is configured to be substantially the same as the groove portion of the packing into which the inner deck cover is inserted.

[0007]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
The prior art of the No. 4 publication fixes the inner deck cover only by the urging force of the leaf spring, the urging member, and the like, and at the joint portion of the joint where the inner deck covers match the cross sections of the respective inner deck covers adjacent to each other, Due to variations in the spring force for fixing the inner deck cover, it is difficult to join and join the cross sections of the seams of the adjacent inner deck covers, and during assembly work, a step is created and passengers' clothes are caught on the step. There is a problem in terms of safety and a problem in that it is unsightly in terms of design due to the occurrence of steps.

In addition, the recently proposed technique in which a step suppressing piece is provided in the upper deck connecting portion of the inner deck cover and is configured substantially the same as the groove portion of the packing to be inserted by the inner deck cover, requires a great amount of time for mounting the step suppressing piece. That is, the dimensional accuracy varies. Further, there is a problem that the number of parts is required to provide the step suppressing piece.

An object of the present invention is a simple structure in which the groove portion of the packing into which the inner deck cover is inserted has an L shape having an opening portion having substantially the same thickness as the thickness of the inner deck cover. It is an object of the present invention to provide a balustrade for a passenger conveyor, which is inexpensive, highly safe, and has an excellent design, which is capable of significantly reducing the time required for assembly work without causing a step.

[0010]

The above object is to provide a design member such as a glass panel constituting a balustrade, an inner deck cover, and a packing, and the packing is provided with an opening for inserting the inner deck cover. In the above,
The packing restrains the height direction of the inner deck cover.
A holding allowance and an L-shaped groove portion,
The height of the opening between the groove and the groove is the plate of the inner deck cover.
This is achieved by making the thickness approximately the same .

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side view near the lower entrance / exit of the passenger conveyor, and FIG. 2 is an embodiment of the present invention.
Sectional view taken along line Z, FIG. 3 is an inner deck cover structure, and FIG.
FIG. 5 is a cross-sectional view showing the relationship between the inner deck cover and the packing which is an embodiment of the present invention, and FIG. 5 is a perspective view showing the respective joint portions of the inner deck cover which is an embodiment of the present invention.

As shown in FIG. 1, a general passenger conveyor is designed so that a step 1 and a moving handrail 2 endlessly travel back and forth between an entrance 3 of one side and an entrance (not shown) of the other side. The balustrade 4 stands upright on both sides of the step 1 to guide and support the outward path of the moving handrail 2. The balustrade 4 has a balustrade panel 5, an inner deck cover 6, an outer deck cover 7, a skirt guard 8, and a packing 9 extruded of plastic or the like on the lower side of the balustrade panel 5 for the entire passenger conveyor. It constitutes the design part.

Here, the inner deck cover 6 extends from the skirt guard 8 side that closes the side portion of the step 1 toward the balustrade panel 5 side and has a structure with an inclined surface, especially at the portion exposed on the front side. Since the unsightly gaps and steps at the respective seams of the inner deck cover 6 are most disliked, it is essential to secure the dimensions of the cross-sectional shape.

Therefore, as a procedure for forming the inner deck cover 6, as shown in FIG. 3, the inner deck cover 6 is bent by bending from the lower end portion 6a to the inclined portion 6b and the upper end portion 6c. The cross-sectional dimension constituted by the total width W1 and the height W2 of 6 is secured, and the variation such as the elongation of the material generated at the time of bending is not exposed on the surface side.
The bending height 6d of the upper end portion 6c of the inner deck cover 6 to be inserted into the groove portion is absorbed.

Therefore, as shown in FIG. 4, the groove opening height 9a of the packing 9 into which the upper end portion 6c of the inner deck cover 6 is inserted.
Is slightly larger than the bending height 6d of the upper end portion 6c of the inner deck cover 6 in consideration of the variation that occurs when the inner deck cover 6 is molded. A slight gap h1 is generated between the groove opening height 9a of the packing 9 and the bending height 6d of the upper end portion 6c of the inner deck cover 6.

Therefore, as shown in FIG. 5, the cross sections of the adjacent seam portions 10 of the inner deck cover 6 do not match, and the step h
2 and when an external force F is applied to the surface side of the inner deck cover 6 due to mischief or the like of passengers' shoes, the inner deck cover 6 is deformed, and each adjacent inner deck In the cross section of the seam portion 10 of the cover 6,
Since the step h2 is generated, not only the safety problem such as the passenger's clothes being caught on the step h2 but also the appearance of the inner deck cover 6 is impaired.

From this, the groove portion of the packing 9 into which the upper end portion 6c of the inner deck cover 6 is inserted has an opening height t1 which is substantially the same as the plate thickness t of the inner deck cover 6, and the inner deck cover 6
L has an opening width t2 wider than the plate thickness t, and a holding margin W3 for the upper end portion 6c of the inner deck cover 6 is provided to configure the packing 9 at the upper end portion 6c of the inner deck cover 6. Since the groove portion is formed with an opening height t1 that is substantially the same as the plate thickness of the inner deck cover 6, the height direction of the inner deck cover 6 can be corrected and restrained, which occurs during assembly work. There is no step adjustment work at each adjacent seam portion 10 of the inner deck cover 6, and the assembly work time is significantly shortened, and passengers' clothes, luggage, etc. can be taken at the step of the longitudinal seam portion 10 of the inner deck cover 6. It is possible to provide an inexpensive and highly safe balustrade for a passenger conveyor without increasing the number of parts and eliminating safety problems such as being caught in the car.

If fine adjustment in the width direction of the inner deck cover 6 is required due to an installation error or the like, the adjustment can be made within the range of the holding margin W3 of the upper end portion 6c of the inner deck cover 6.

Furthermore, since dust can be prevented from entering through the gap generated at the step of the seam portion 10 in the longitudinal direction of the inner deck cover 6 and rainwater and the like can be prevented from entering in the passenger conveyor installed outdoors. Since the internal equipment of the passenger conveyor can be kept clean, the life of the internal equipment of the passenger conveyor can be extended, and a clean, long-life passenger conveyor can be provided.

[0020]

According to the present invention, the groove portion of the packing into which the inner deck cover is inserted is formed into an L shape having an opening having substantially the same thickness as the thickness of the inner deck cover. Since there is no step adjustment work at the longitudinal seams, there is no step or gap in the longitudinal seams of the inner deck cover that occurs during assembly work, and safety such as passenger clothes getting caught at the seam steps Since the above problems are eliminated and the assembly work is easy and accurate, the assembly work time can be greatly shortened, the number of parts is not increased, the cost is low, and the design is excellent and the passenger conveyor is highly safe. The parapet can be provided.

Furthermore, since it is possible to prevent dust from entering through a gap generated at the step of the seam portion in the longitudinal direction of the inner deck cover and to prevent rainwater and the like from entering the passenger conveyor installed outdoors, it is possible to prevent the passenger conveyor from operating. Since the internal equipment can be kept clean, the life of the internal equipment of the passenger conveyor can be extended, and a clean and long-life passenger conveyor can be provided.
