Abstract

PURPOSE:To drive the travel of a handrail without causing damage due to pressing force by forming a number of recessed and projected parts lengthwise at equal intervals on the center part of the inside face of the handrail, and engaging gear-shaped driving wheels with the recessed and projected parts to rotate and drive the handrail. CONSTITUTION:A number of recessed parts 11, projected parts 12 are provided lengthwise at equal intervals on the center part of the inside face of a handrail 10. Two driving wheels 13 whose outer peripheries are shaped into gear-shape, are engaged with the recessed and projected parts 11, 12. Further, roller type driven wheels 14 are arranged beneath the handrail 10 on the opposite side from the driving wheels 13. Thus, the handrail can travel without giving frictional force due to strong pressing force to the handrail 10 between the driving wheels 13 and the driving wheels 14, and pressure applied to the surface of the handrail 10 can be substantially reduced to reduce damage, wear to the surface.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a method for driving an escalator handrail.

(Prior Art) Conventionally, as shown in FIGS. 3 and 4, an escalator handrail 1 is made of a main body 1a formed of rubberized canvas or the like into a C-shaped cross section, and covered with decorative rubber 1b on the outer surface.
When in use, the flat part at the center is held between two pairs of roller-shaped drive wheels 2 and driven wheels 3, and is appropriately pressurized to drive each drive wheel 2 to rotate. has been done.

(Problems to be Solved by the Invention) However, the conventional escalator handrail 2 drive method described above has the following drawbacks.

That is, in order to prevent slipping with the handrail 2,
Since it is necessary to apply considerable pressure to the handrail 2 by the driving wheel 2 and the driven wheel 3, the decorative rubber 1b
Since the outer surface of the driven wheel 3 is easily deteriorated or damaged due to wear, and the roller-shaped driven wheel 3 is always strongly pressed against the decorative rubber 1b, foreign matter such as dust attached to the driven wheel 3 may be easily damaged. Due to pressure, it was sometimes transferred to the outer surface of the decorative rubber, causing stains.

SUMMARY OF THE INVENTION The present invention has been made to solve these conventional problems, and it is an object of the present invention to provide a method for driving an escalator handrail that can maintain good quality of the handrail even during long-term operation. shall be.

[Structure of the Invention (Means for Solving the Problems) The method for driving an escalator handrail of the present invention includes disposing a driving wheel and a driven wheel on the inner and outer surfaces of the central portion of the handrail, respectively, and rotating the driving wheel. In a method of driving an escalator handrail in which the handrail is driven to run, a large number of concave and convex portions are provided at equal intervals along the length direction on the inner surface of the central portion of the handrail, and these concave and convex portions are provided with gear-shaped and It is characterized by running on handrails by engaging and rotating the drive wheels.

(Function) The method for driving the escalator handrail of the present invention as described above is achieved by rotating a gear-shaped drive wheel by meshing it with the uneven part provided on the inner surface of the central part of the handrail. Since the driving force of the handrail is significantly increased compared to the above-described conventional driving method using only frictional force, the pressure applied to the surface of the handrail by the driving wheel and the driven wheel can be reduced.

(Example) Hereinafter, a method for driving an escalator handrail according to the present invention will be described according to an example shown in the drawings.

FIG. 1 and FIG. 2 are diagrams showing one embodiment of the present invention.

In these figures, a handrail 10 having a C-shaped cross section has a large number of concave portions 11 and convex portions 12 provided at equal intervals along its length on the inner surface of its central portion.

Two pairs of driving wheels 13 and two pairs of driven wheels 14 are arranged on the inner and outer surfaces of the central portion of the handrail 10, respectively. The two drive wheels 13 are gear-shaped and mesh with the recess 11 and projection 12 of the handrail.

The driven wheel 14 has a roller shape.

The handrail 10 is rotated by the driving wheel 13.
runs.

In addition, as shown in FIG. 1, when one drive wheel 13 is engaged with a convex part at part A in the figure of the handrail, the other drive wheel 13 is engaged with a concave part at part B of the handrail. By adjusting the interval between the drive wheels 13 and the handrail 10, the play gap between the drive wheel 13 and the handrail 10 can be reduced and the handrail can run smoothly.

It goes without saying that the present invention is not limited to the use of two pairs of driving wheels and driven wheels.

[Effects of the Invention] As explained above, according to the method for driving an escalator handrail of the present invention, the handrail having an uneven portion on the inner surface of the central portion is driven by a gear-shaped drive wheel. By doing so, it is possible to significantly reduce the pressure applied to the outer surface of the handrail, thereby reducing surface contamination, wear, damage, etc.

Therefore, the quality of the handrail can be maintained well for a long period of time.
