본 고안은 휠체어용 캐스터바퀴에 관한 것으로, 특히 바퀴프레임부분에 탄성재질의 타이어부분이 확고하게 결합되어 사용중에 바퀴프레임부분에서 타이어부분의 탈거되지 않도록 한 휠체어용 캐스터바퀴에 관한 것이다.The present invention relates to a caster wheel for a wheelchair, and more particularly, to a caster wheel for a wheelchair so that the tire portion of the elastic material is firmly coupled to the wheel frame portion so that the tire portion is not removed from the wheel frame portion during use.

종래의 휠체어용 캐스터바퀴에 있어서는 휠체어에 앉아 있는 사람의 체중 일부가 가하여지며 휠체어의 방향전환을 유도하는 캐스터바퀴의 타이어부분이 바퀴프레임에 확고하게 결합되어 있지 못하여 특히 방향전환시 타이어부분에 가하여지는 비틀림 모멘트에 의하여 바퀴프레임부분에서 타이어부분이 쉽게 탈거되는 결점이 있었다.In a conventional caster wheel for a wheelchair, a part of the weight of a person sitting in a wheelchair is applied, and the tire part of the caster wheel for inducing the direction of the wheelchair is not firmly coupled to the wheel frame, and thus is particularly applied to the tire part during the change of direction. There was a defect that the tire part was easily removed from the wheel frame part by the torsional moment.

본 고안에 있어서는 종래의 이와 같은 점을 감안하여 안출한 것으로, 바퀴 프레임부분에 탄성재질의 타이어부분이 거의 일체로 성형되어 확고하게 결합되게 하므로서 바퀴프레임부분으로부터 타이어부분이 탈거되지 않도록 한 것인 바, 이를 첨부도면에 의거하여 보다 상세히 설명하면 다음과 같다.In the present invention, in view of such a conventional point, it is designed to prevent the tire portion from being removed from the wheel frame portion by making the tire portion of the elastic material almost integrally molded and firmly coupled to the wheel frame portion. On the basis of the accompanying drawings, it will be described in more detail as follows.

바퀴 프레임부분(10)에 탄성재질의 타이어부분(12)이 환착되어 결합되는 휠체어용의 캐스터바퀴(14)에 있어서, 바퀴 프레임부분(10)의 외면에 외향플랜지(16)를 갖는 한 쌍의 평행한 원형리브(18)(18')를 형성하고 이들 원형리브(18)(18')에 수개의 원형통공(20)을 형성하여 타이어부분(12)이 이를 구성하는 탄성재료가 바퀴 프레임부분(10)의 외면에서 원형리브(18)(18')의 둘레와 원형통공(20)에 채워져 바퀴프레임부분(10)에 일체가 되게 성형되어 구성됨을 특징으로 한다.In the caster wheel 14 for wheelchairs, in which the tire portion 12 of the elastic material is coupled to the wheel frame portion 10 and coupled thereto, a pair of outward flanges 16 on the outer surface of the wheel frame portion 10 are provided. An elastic material forming the parallel ribs 18 and 18 'and forming a plurality of circular through holes 20 in the circular ribs 18 and 18' so that the tire portion 12 constitutes the wheel frame portion The outer surface of the (10) is filled in the periphery of the circular ribs (18, 18 ') and the circular through hole 20 is characterized in that it is configured to be integrally formed on the wheel frame portion (10).

이와같은 본 고안은 탄성재질의 타이어부분(12)이 바퀴프레임부분(10)의 외면에 형성된 원형리브(18)(18')에 의하여 캐스터바퀴(14)의 직경방향으로 지지되어 하중에 의하여 타이어부분(12)이 변형되는 것이 방지될 수 있으며, 또한 타이어부분(12)이 이를 구성하는 탄성재료가 원형리브(18)(18')를 둘러싸고 또한 이들 원형리브(18)(18')에 형성된 원형통공(20)에 채워져 있으며 원형리브(18)(18')를 둘러싸고 있는 상태에서는 이들 원형리브(18)(18')에 형성되어 있는 외향플랜지(16)에 의하여 고정적으로 바퀴프레임부분(10)에 일체가 되게 성형되어 있으므로 타이어부분(12 )이 휠체어의 방향 전환을 유도할 때에 가하여지는 비틀림모멘트에 의하여 탈거되는 것이 방지될 수 있는 것이다.The present invention is such that the tire portion 12 of the elastic material is supported in the radial direction of the caster wheel 14 by the circular ribs 18, 18 'formed on the outer surface of the wheel frame portion 10, the tire by the load It is possible to prevent the portion 12 from being deformed, and the elastic material constituting the tire portion 12 also surrounds the circular ribs 18, 18 'and is formed on these circular ribs 18, 18'. In the state filled in the circular hole 20 and surrounding the circular ribs 18 and 18 ', the wheel frame part 10 is fixedly fixed by the outward flange 16 formed in these circular ribs 18 and 18'. Since the tire 12 is prevented from being detached by the torsional moment applied when the tire portion 12 is induced to change the direction of the wheelchair.
