Description

무베어링 캐스터{BEARINGLESS CASTER}Bearingless Casters {BEARINGLESS CASTER}

본 발명은 바퀴.휠(Wheel)이 구비된 캐스터(Caster)에 관한 것으로, 일반적으로 캐스터는 도6에서 물체의 저면 또는 측면에 부착되어 측에서 가해지는 측압에 종(從)하여 방향을 전환하며 이동하는 요소로 사용되고 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a caster equipped with wheels and wheels. In general, casters are attached to the bottom or side of the object in FIG. It is used as a moving element.

한편, 도5에서 상기 캐스터를 일정각경사(a1) 경사지게 부착하는 경우에는, 물체를 좌우로 기울여 경사시키는 만큼의 진행방향을 전환하므로 이때는 방향성 캐스터(Directional Caster)라고 불리우고 있으며 이와 같은 방향성 캐스터는 특히 스케이트보드(Skateboard)와 같은 승물(乘物)의 방향전환을 하는 조향수단 요소로 다수 사용되고 있다.On the other hand, in FIG. 5, when the caster is inclined at a predetermined angle inclination (a1), since the moving direction is changed as much as the inclination of the object is inclined to the left and right, this is called a directional caster. It is widely used as a steering means element for changing the direction of a vehicle such as skateboard.

도4에서 일반적인 캐스터의 구조를 살펴보면 물품.물체의 저면에 부착하는 고정부(10), 휠(W)을 축회전 가능케 결합.지지하는 휠브라킷(30), 상기 고정부와 상기 휠브라킷을 핀결합시켜 회전 가능케하는 스핀들(Spindle), 상기 물체의 중량을 지탱하며 상기 스핀들의 회전을 자유롭게 돕는 베어링(Bearing)으로 구성되는 회전부(20)가 있다.Looking at the structure of a typical caster in Figure 4, the fixing part 10 attached to the bottom surface of the object, the wheel bracket 30 is coupled to enable the rotation of the wheel W. Supporting the wheel bracket 30, the fixing part and the wheel bracket pin There is a rotating spindle (20) consisting of a spindle (Rodder) coupled to enable rotation, the bearing (Bearing) to support the weight of the object and to freely rotate the spindle.

여기서, 승물과 같은 사용대상 물체 및 다른 대부분 사용대상 물체에는 상기 고정부에 대하여 휠브라킷이 360도 회전을 요하지 않고 회절(回折) 작용으로 방향전환 목적을 충분히 달성할 수 있으므로, 상기 회전부의 스핀들과 베어링은 상기 캐스터의 중량과 부피와 가격을 증가 시키는 요인이 될 뿐이다.Here, the object to be used, such as the object and most other objects to be used, since the wheel bracket does not require a 360-degree rotation with respect to the fixed portion can sufficiently achieve the purpose of redirection by diffraction (작용), the spindle and the Bearings will only increase the weight, volume and price of the casters.

본 발명은 상대적으로 고가이며, 체적이 크고, 중량이 큰 베어링 및 스핀들을 비사용하므로써, 저렴하고 저체적, 저중량의 캐스터를 제공하여 스케이트보드 등 캐스터 사용대상 물체의 전체 중량과 가격과 부피를 감소시키고자 한다.The present invention provides a low cost, low volume, low weight caster by using relatively expensive, large volume, heavy bearings and spindles, thereby reducing the total weight, price and volume of the caster object such as a skateboard. I want to.

첨부하여, 상기 캐스터에 가해지는 측압이 제거된 후에는 상기 캐스터의 휠브라킷이 원위치 복귀하는 캐스터를 제공하고자 한다.In addition, it is intended to provide a caster in which the wheel bracket of the caster returns to its original position after the side pressure applied to the caster is removed.

따라서 본 발명은 상기 베어링 및 스핀들의 구성을 생략하고 대신에 굴절.회절이 가능한 굴절편을 사용하여 이른바 플립힌지(Hinge)의 형태로 제공하므로써 회절작용이 되도록 한다.Accordingly, the present invention omits the configuration of the bearing and the spindle, and instead uses a refractive piece that is capable of refracting and diffraction, so that it is provided in the form of a so-called flip hinge (Hinge) to be diffracted.

본 발명에 따르는 캐스터는 상대적으로 고가이며, 체적이 크고, 중량이 큰 베어링 및 스핀들을 비사용하므로써, 저렴하고 저체적, 저중량의 캐스터를 제공하므로 스케이트보드 등 캐스터 사용대상 물체의 전체 중량과 가격과 부피를 감소하는 효과가 있고 특히, 상기 베어링 및 스핀들 대신 사용되는 굴절편이 탄성체인 경우 상기 캐스터에 가해지는 측압이 제거된 후에는 상기 캐스터의 휠브라킷이 원위치 복귀하는 효과가 있다.The caster according to the present invention is relatively inexpensive, has a large volume, and does not use a large bearing and spindle, thereby providing an inexpensive, low volume, low weight caster, and thus the total weight and price of the caster object such as a skateboard. There is an effect of reducing the volume, and in particular, when the deflection piece used in place of the bearing and the spindle is an elastic body, after the side pressure applied to the caster is removed, the wheel bracket of the caster returns to its original position.

이하, 첨부된 도면을 참조하여 본 발명을 개시하기로 한다.Hereinafter, the present invention will be described with reference to the accompanying drawings.

도1에서, 물체의 저면에 부착하며 굴절편을 지지하는 고정부(100)가 구비되어 있는바 상기 고정부는 비단 물체의 저면 뿐만 아니라 당업자의 필요에 따라 물체의 측면 등에 부착될 수 있도록 형상을 변경할 수 있고 또한, 물체의 저면에 부착하는 경우 상기 부착을 용이하도록 캐스터 부착부(P)를 포함할 수 있으며 상기 캐스터 부착부는 도면과 같이 물체의 저면이 평면이라면 그에따라 평면형태로 할 수 있으며 만일 물체의 저면이 요철이 형성되는 등 특정한 형태를 하고 있다면 이에 따라 그 형태를 변경될 수 있음은 물론이다. 또한 쐐기 형태 또는 나사선이 형성된 나사형태의 돌출부(또는 요부) 형태를 취할수 있으며 이 경우 물체의 저면에 요부.구멍(또는 돌출부)을 형성되도록 하여 상기 구멍에 상기 돌출부를 끼워 고정하도록 할 수 있으며 이러한 구성은 기존의 기술에서 공지되어 있으므로 이를 인용한다.In FIG. 1, a fixing part 100 is attached to a bottom of an object and supports a deflection piece. In addition, when attached to the bottom of the object may include a caster attachment portion (P) to facilitate the attachment, and the caster attachment portion may be in a planar shape accordingly if the bottom of the object is flat as shown in the figure If the bottom of the specific shape, such as irregularities are formed, of course, the shape can be changed accordingly. It may also take the form of a wedge or threaded protrusions (or recesses), in which case recesses or holes (or protrusions) are formed on the bottom of the object to allow the protrusions to fit into the holes. Is known in the art and cited.

휠브라킷(300)이 구비되며 상기 휠브라킷은 구름운동 가능토록 축결합된 휠(W)을 포함하고 이때 상기 휠브라킷은 캐스터 아암(Arm)의 역할을 수행할 수 있다.The wheel bracket 300 is provided, and the wheel bracket includes a wheel W that is axially coupled to enable rolling motion, and the wheel bracket may serve as a caster arm.

굴절편(200)이 구비되며 상기 굴절편의 일 측은 상기 고정부(100)에 고정되고 타 측은 상기 휠브라킷(300)에 고정된다.A deflection piece 200 is provided and one side of the refraction piece is fixed to the fixing part 100 and the other side is fixed to the wheel bracket 300.

여기서, 상기 굴절편은 가소성/가요성 또는 탄성을 보유하는 재질 요컨대 직조물, PE, 합성수지, 탄소섬유, 유리섬유, 금속, 플라스틱, 나노섬유, 판스프링 등 굴절이 가능하다면 특정한 부재에 한정되지 않으며 이 중 탄성복원력이 부여된 탄성부재가 상기 굴절편으로 사용되는 경우 상기 캐스터에 가해지는 측압이 제거된 후에는 상기 캐스터의 휠브라킷이 자동으로 원위치 복귀된다.Here, the refraction piece is a material having plasticity / flexibility or elasticity, that is, a woven material, PE, synthetic resin, carbon fiber, glass fiber, metal, plastic, nanofiber, leaf spring, etc., if the refraction is possible, it is not limited to a specific member. When the elastic member given the elastic restoring force is used as the deflection piece, the wheel bracket of the caster is automatically returned to its original position after the side pressure applied to the caster is removed.

또한, 상기 고정의 형태는 상기 고정부에 요입된 형태의 끼움부 갭(Gap)을 두고 상 기 굴절편의 단부를 상기 갭에 끼워 고정; 상기 고정부와 상기 굴절편의 단부를 고정핀, 나사와 같은 고정요소를 사용하여 고정할 수 있으며 이 외에 물체와 물체사이를 고정하는 공지의 방법을 사용할 수 있다. 이 때 상기 굴절편을 상기 휠브라킷에 고정하는 경우도 상기한 바와 동일할 수 있음은 물론이다.In addition, the fixed form is fixed by inserting the end of the refractive piece in the gap with a gap (Gap) of the recessed in the fixed portion; The fixing part and the end of the deflection piece may be fixed using a fixing element such as a fixing pin or a screw. In addition, a known method of fixing the object and the object may be used. At this time, the case of fixing the deflection piece to the wheel bracket may be the same as described above.

한편, 상기 캐스터는 도2에서 물체에 저면에 각도 a2의 경사를 주면 기존의 방향성 캐스터와 같은 구성이 가능하다.On the other hand, the caster can be configured like the conventional directional caster when the inclination of the angle a2 on the bottom surface to the object in FIG.

또한, 도3에서는 본 발명 캐스터의 동작을 표현하고 있는데, 상기 굴절편(200)이 굴절하면서 방향을 바꾸는 것을 도시한다.3 illustrates the operation of the caster of the present invention, which shows that the deflection piece 200 changes direction while refracting.
