Problems solved by technology

Due to the high rigidity, it cannot fit the guide rail properly, causing problems such as large wear of the guide rail, large wear of the driving roller, high running resistance, loud running sound, noise from the joint of the guide rail, and vibration (vibration) of the armrest, etc.
In addition, in the armrest of Patent Document 2, the tensile member adopts a metal belt, and the problem of rigidity is estimated to be worse.

[0025] Fig. 1 is a sectional view of an armrest according to a first embodiment of the present invention. In Fig. 1, handrail 1 comprises: the tensile body 2 that is arranged continuously along the length direction of handrail 1; The core material layer 3 that is formed on the periphery of tensile body 2 is made of thermoplastic elastic material for core material layer; Covers the core material The outer periphery of layer 3 has also formed the decorative layer 4 that the cross-section shape is C-shaped and is made of thermoplastic elastic material for the decorative layer; The thermoplastic elastic material for the decorative layer has a hardness lower than that of the thermoplastic elastic material for the core layer. The armrest 1 having a C-shaped cross-sectional shape as a whole has a substantially flat central portion 6 and side end portions 7 that are bent from the central portion 6 .

[0026] First, the core material layer will be described.

[0032] Fig. 2 is a sectional view of an armrest according to a second embodiment of the present invention. The same symbols as in Fig. 1 are attached to the same parts in Fig. 2 as in Fig. 1 . The difference from the first embodiment is that the length of the core material layer 3 surrounding the tensile body 2 is formed longer in the width direction and reaches the region of the side end portion 7 of the handrail 1 . Although the thickness of the core material layer 2 is substantially constant in FIG. 2 , the portion reaching the side end portion 7 may be formed thicker.

[0033] Fig. 3 is a graph showing the rigidity of the armrest. FIG. 3 shows the relationship between load and bending of a conventional polyurethane handrail, a handrail according to the first embodiment of the present invention, a handrail according to the second embodiment of the present invention, and a rubber handrail. The polyurethane handrail of the prior art is the handrail shown in Figure 10, the f...

Abstract

Due to high rigidity, the prior handrail made of thermal plastic can not match with the guiding rail, which leads to the problems such as high wear of the guiding rail and a driving roll, high running resistance, loud running noise, noise at the joints on the guiding rail, fibrillation (vibration) on the handrail and so on. So the invention provides a handrail made of thermal plastic used for reducing the rigidity and eliminating problems caused by the over-high rigidity. The handrail (1) is provided with: a tensile unit (2) arranged continuously along the direction of the handrail (1) length; a core layer made of thermal plastic flexible materials and arranged around the tensile unit (2); a decorate layer (4) with a C-shape section form made of decorate thermal plastic flexible materials with a hardness lower than that of thermal plastic flexible materials making up the core layer and used for covering the surface of the core layer; and an inner surface canvas layer (5) with a C-shape section form stuck on the decorate layer (4).

Description

technical field [0001] The present invention relates to the construction of moving handrails for escalators, moving walkways, and conveying devices like these, and to a method for their manufacture. Background technique [0002] As conventional handrails, rubber handrails are mainly used. [0003] As another conventional handrail, there is a handrail made of a thermoplastic material (for example, Patent Document 1: Japanese Patent No. 3604687). Fig. 10 is a sectional view of a conventional armrest made of thermoplastic material. In Fig. 10, the handrail 10 includes a first thermoplastic elastic material layer 11, a second thermoplastic elastic material layer 12, a tensile body 13 embedded in the first thermoplastic elastic material layer 11, and a The inner canvas layer 14 . It is characterized in that the first thermoplastic elastic material layer 11 is harder than the second thermoplastic elastic material layer 12 . [0004] Handrails made of thermoplastic materials ca...
