The specific embodiment
Below, based on accompanying drawing embodiments of the present invention are described.
Fig. 1 relates to the section drawing of the handrail of embodiment of the present invention.Among Fig. 1, handrail 1 is to be made of tension thing 2, core layer 3, decorative layer 4, canvas layer 5, wherein, tension thing 2 is arranged at the longitudinal direction of handrail 1 continuously, core layer 3 is to be made of with the thermoplastic elastic thing the core layer that forms cross sectional shape C word shape around tension thing 2, decorative layer 4 is that the decorative layer that is formed cross sectional shape C word shape by the outside of the cross sectional shape C word shape that is coated on core layer 3 constitutes with the thermoplastic elastic thing, and canvas layer 5 is lining in the inner face of the cross sectional shape C word shape of core layer 3 in being.Decorative layer uses the elastic with same rigidity with thermoplastic elastic thing and core layer with the thermoplastic elastic thing.As a whole, the handrail 1 of cross sectional shape C word shape has the middle body 6 of general planar and forms the side part 7 of sweeps from middle body 6.
The core layer: the purpose of core layer 3 is the destruction that protection tension thing 2 is avoided external stress, buries tension thing 2, makes handrail 1 single-piece cross sectional shape form C word shape.Sidelining has canvas layer 5 in the C word shape of the cross section of core layer 3.The core layer is a polyurethane with the material of thermoplastic elastic thing, and hardness is expressed as 84～88 with the Durometer A hardness scale.As core layer thermoplastic elastic thing, can use polyester is that elastic, nylon are elastic, ethylene series elastic etc.
Decorative layer: decorative layer 4 is coated on the outside of the cross sectional shape C word shape of core layer 3, and cross sectional shape forms C word shape.Decorative layer uses with the thermoplastic elastic thing to have and the material of core layer with thermoplastic elastic thing same rigidity.Decorative layer is a polyurethane with the material of thermoplastic elastic thing, and hardness preferably is expressed as 84～88 with the Durometer A hardness scale.Can use polyester as decorative layer with the thermoplastic elastic thing is that elastic, nylon are elastic, ethylene series elastic etc.
Fig. 3 is the chart that shows the rigidity of handrail.In Fig. 3, illustration the polyurethane handrail of conventional art, the handrail of embodiment of the present invention, loading and the Deflection Relationship in the rubber system handrail.In the polyurethane handrail of conventional art, the 1st thermoplastic elastic thing layer (core layer) accounts for 60% of handrail integral thickness, be that hardness by the Shore D scale is that 40～50 polyurethane constitutes, the 2nd thermoplastic elastic thing layer (decorative layer) is that the hardness by the Shore D scale is that 70～85 polyurethane constitutes.Use steel cord in the tension thing, use the textile of natural fiber or syntheticfibres in the canvas layer.It is 84～88 polyurethane as the core layer of the core layer 3 decorative layer thermoplastic elastic thing with thermoplastic elastic thing and decorative layer 4 that the handrail of embodiments of the present invention is to use the hardness of Durometer A hardness scale.In the handrail of embodiments of the present invention, the core layer of core layer 3 uses the polyurethane of same rigidity with the thermoplastic elastic thing with the decorative layer of thermoplastic elastic thing and decorative layer 4.And, the core layer that uses core layer 3 with the decorative layer of the hardness of thermoplastic elastic thing and decorative layer 4 with the hardness of thermoplastic elastic thing be all with the Durometer A hardness scale be expressed as hardness 80 polyurethane handrail as a comparative example.
On the other hand, Fig. 4 has shown the opening power of handrail.In Fig. 4, be that the anchor clamps of 48mm place handrail with length direction, be under 15 ℃ the condition in the atmosphere temperature, show side end with cross sectional shape C word shape divide between the width of (opening portion) enlarge the needed power of 7mm (opening power).Usually, the opening power (being about 130N) of the handrail that is made of in the past thermoplastic material is littler than the opening power (being about 183N) of rubber system handrail.This is because the canvas layer of the handrail that is made of thermoplastic material is 1 layer, and to compare the number of plies few with 3 to 5 layers of in the past rubber system handrail, and thus, the power (opening power) in the time of between the side end of the enlarged cross section shape C word shape branch is just little.
As can be seen from Figure 3, the handrail of embodiments of the present invention is compared less rigid with the polyurethane of conventional art, has and the equal rigidity of the rigidity of rubber system handrail.This is owing to make the core layer identical with decorative layer hardness.Thus, utilize the structure of the handrail of embodiments of the present invention, can make less rigid, be suitable for being wedged in the guide piece, so can remove owing to the abrasion of the guide piece of the big generation of rigidity, the abrasion of head roll, big transmission resistance, big transmission sound, the noise of guide piece junction, the problems such as (vibrations) that flutters of handrail, can obtain being suitable for the handrail of transmission.
