Abstract

PROBLEM TO BE SOLVED: To provide a wheel with a rotating roller having different diameters which prevents the wheel from falling to a street gutter on a road or a side gutter of a rail in a railway crossing and also prevents the wheel from being buried on a gravel road.SOLUTION: A wheel with a rotating roller having different diameters includes a first rotating roller part having a diameter larger than a diameter of a second rotating roller part, in parts on a circumference of the rotating roller; during a normal travel, travels with the first rotating roller part having a larger diameter to make a surface area thereof to contact the ground smaller, and can prevent the wheel from falling and being buried by means of the second rotating roller having a smaller diameter.

Description

本発明は、回転コロの直径が異なる車輪を台車又は、車椅子などにとりつけて、側溝、砂利道などに落輪、車輪が埋没して走行できなくなることを防止するための車輪に関するものである。The present invention relates to a wheel for attaching a wheel having a different diameter of a rotating roller to a carriage or a wheelchair to prevent a wheel from falling on a side groove, a gravel road, or the like from being buried and running.

従来の台車又は車椅子などは、側溝又は砂利道などでの走行時、落輪又は車輪の埋没を防止できる機能を有した車輪に関するものはなかった。None of conventional trolleys or wheelchairs are related to wheels having a function of preventing falling wheels or burying of wheels when traveling on a gutter or a gravel road.

介護用車椅子や台車などが走行時側道に敷設されている側溝上又は、電車の踏切内の路上のレールの側溝などへ車輪が落輪して動かなくなったり、砂利道上で車輪が砂利に埋没して動かなくなったりする難点があった。本発明は、この危険な難点を解消するためになされたものである。Wheelchairs and carts for nursing care are stuck on the side gutters that are laid on the side roads when traveling, or the side gutters of rails on the streets in train crossings, etc. There was a difficult point to get stuck. The present invention has been made to solve this dangerous problem.

中心部にシャフト貫通孔を設けた大小異なる直径を有した回転コロ１、２をシャフト３を介して車輪軸受５に回転自在に装着して形成した回転コロの直径が異なる車輪を台車又は車椅子に装着するものである。A rotating roller 1 or 2 having a shaft through hole in the center and having different diameters is mounted on a wheel bearing 5 via a shaft 3 so as to be rotatable. It is what you wear.

直径の大きさが異なる回転コロ１、２を形成する回転コロの直径が異なる車輪を台車又は車椅子に装着することにより、通常の走行をするときは、直径の大きい回転コロ２を使用することにより、接地面を狭くすることができ軽い力で走行でき、さらに直径の小さい回転コロ１が補助輪となり、側溝に落輪することなく、又砂利道においては回転コロ１と２が埋没することなく、簡単に走行できるものである。By mounting the wheels with different diameters of the rotating rollers 1 and 2 forming the rotating rollers 1 and 2 having different diameters on the carriage or the wheelchair, by using the rotating roller 2 having a larger diameter when traveling normally, The grounding surface can be made narrow and the vehicle can be driven with a light force. Further, the rotating roller 1 having a small diameter serves as an auxiliary wheel and does not fall into the side groove, and the rotating rollers 1 and 2 are not buried on the gravel road It can run easily.

以下、本発明の実施形態について説明する。
（イ）円周の中心部にシャフト貫通孔３を設けた適宜直径の回転コロ１の円周上に、これより直径の大きい回転コロ２を一体化して形成してなる回転コロ１、２にシャフト４を介して車輪軸受５に回転自在に装着してなるものである。
（ロ）円周の中心部にシャフト貫通孔３を設けた適宜大きさの直径の回転コロ２の両側部に、この回転コロ２より直径が適宜小さく、中心部にシャフト貫通孔３を設けた回転コロ１を接着し、シャフト４を介して車輪軸受５に回転自在に装着してなるものである。Hereinafter, embodiments of the present invention will be described.
(A) On the circumference of a rotary roller 1 having an appropriate diameter provided with a shaft through-hole 3 in the center of the circumference, the rotary rollers 1 and 2 formed by integrating a rotary roller 2 having a larger diameter than this A wheel bearing 5 is rotatably mounted via a shaft 4.
(B) The diameter of the rotary roller 2 having an appropriately sized diameter provided with the shaft through hole 3 in the center of the circumference is appropriately smaller than the diameter of the rotary roller 2, and the shaft through hole 3 is provided in the center. The rotating roller 1 is bonded, and the wheel roller 5 is rotatably mounted via a shaft 4.
