Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a handrail repair device.

Furthermore, to be more specific, the present invention is to scrape off the appearance defective area when a surface cosmetic rubber layer of a handrail has a defective appearance area, and after scraping off the appearance defective area, press vulcanize and bond an unvulcanized decorative rubber sheet. This invention relates to a handrail repair device that can be used to repair handrails.

[Prior Art] Handrails are used as handrails on escalators and auto lines. For this reason, the handrail is touched by an unspecified number of people. As a result, stains, damaged areas, cracks, etc. that cannot be removed by wiping occur on the decorative rubber surface layer of the handrail, and it is often necessary to partially repair the decorative rubber layer.

This decorative rubber layer is made of vulcanized rubber, but if a vulcanized sheet of decorative rubber is simply adhered with an adhesive, a product that is satisfactory in both appearance and strength cannot be obtained.

For this reason, conventional partial repairs of the decorative rubber layer of handrails are carried out by first removing the handrail from the escalator or auto line, taking it back to the factory, grinding out any external defects, and then covering the area with an unvulcanized decorative rubber sheet. The method used was press vulcanization and bonding using large handrail manufacturing equipment. Therefore, repair work was required, and a decline in the operating rate of escalators and auto lines was unavoidable.

[Problems to be solved by the invention] This invention was developed based on this point, and its purpose is to partially repair handrails at sites where escalators and automatic lines are installed. Our goal is to provide a handrail repair device that is capable of repairing handrails.

[Means for solving the problem] The gist of the present invention is that there is a core having the same shape as the inside shape of the ear of the handrail;
A handrail repair characterized in that there is a press vulcanized member having the same shape as the outer shape of the ear of the handrail at an oblique position of the core, and the press vulcanized member is provided with a torque clamp mechanism. It's in the device.

[Function] The function and effect of the handrail repair device of the present invention are as follows.
It is small and lightweight, making it easy to carry to the site, and by operating the core and press vulcanization member with a torque clamp mechanism, the unvulcanized decorative rubber sheet can be quickly and easily brought into contact with external defects on the handrail. , after such press vulcanization, it can be bonded.

[Embodiment] Next, an embodiment of the handrail repair device of the present invention will be described with reference to the drawings.

The drawing is an explanatory view showing a state in which a handrail ear is being repaired using an embodiment of the handrail repair device of the present invention.

In the drawing, 1 is a handrail, 2 is an ear part of the handrail, 20 is a torque clamp mechanism, and 21
22 is a support member, 22 is a press vulcanization member, 23 is a heater built into the press vulcanization member, and 24 is a core.

In the drawing, there is a surface defect on the outer R part of the ear 2 of the handrail 1, and after the surface defect is ground with a knife or the like, an unvulcanized decorative rubber sheet is applied to fill the ground part. ing.
Then, the tip of the press vulcanized member 22 of the handrail repair device of the present invention is brought into contact with the outer R part of the ear part 2 on which the unvulcanized decorative rubber sheet of the drawing is applied, and the inner R part of the ear part 2 is brought into contact. The core 24 is brought into contact with the core 24, and then heated and vulcanized by the press vulcanization member 22 while being pressed by the torque clamp mechanism 20.
It is something to be glued.

[Effects of the invention] By using the handrail repair device of the present invention, surface defects of the handrail can be repaired very easily and quickly at the site where the handrail is installed, and is industrially useful.

[Brief explanation of the drawing]

The drawing is an explanatory diagram showing a situation in which an unvulcanized decorative rubber sheet is press-vulcanized and adhered to an externally defective part of the decorative rubber layer of a handrail using an embodiment of the handrail repair device of the present invention. . 1: Handrail, 2: Handrail ear,
20: Torque clamp mechanism, 21: Support member, 2
2: Press vulcanized member, 23: Heater, 24: Core.

Claims (1)

[Scope of utility model registration request] There is a core having the same shape as the inside shape of the ear of the handrail, and a press vulcanized member having the same shape as the outside shape of the ear of the handrail is located diagonally to the core, and the press vulcanized member has the same shape as the outside shape of the ear of the handrail. A handrail repair device characterized by being equipped with a torque clamp mechanism.
