본 실시예의 래칫장치(100)는, 정회전 방향(A)을 향하여 개방된 래칫홈(112)이 외주에 형성된 래칫기어(110) 및 래칫기어(110)의 정회전 시에 래칫기어(110)에 의해 회전되는 래칫휠(120)을 포함한다. 여기서, 래칫훨은 래칫돌 기(122), 래칫돌기(122)를 지지하는 지지부(124)를 포함한다.In the ratchet device 100 according to the present embodiment, the ratchet gear 110 in which the ratchet groove 112 opened toward the forward rotation direction A is formed on the outer circumference of the ratchet gear 110 and the ratchet gear 110 at the forward rotation thereof. It comprises a ratchet wheel 120 rotated by. Here, the ratchet hatch includes a ratchet protrusion 122 and a support 124 for supporting the ratchet protrusion 122.

래칫기어(110)는 래칫휠(120)을 정회전 방향(A)으로 회전시키는 부분으로, 도 4 및 도 6에 도시된 바와 같이, 정회전 시에 후술할 래칫휠(120)의 래칫돌기(122)가 걸릴 수 있도록 외주에 정회전 방향(A)을 향하여 개방된 래칫홈(112)이 형성되어 있다.The ratchet gear 110 rotates the ratchet wheel 120 in the forward rotation direction A. As shown in FIGS. 4 and 6, the ratchet protrusion 110 of the ratchet wheel 120 to be described later during forward rotation ( The ratchet groove 112 which is opened toward the forward rotation direction A is formed in the outer periphery so that 122 may be caught.

래칫돌기(122)는 정회전 시에 래칫기어(110)에 의해 회전력을 전달받는 부분으로, 정회전 시에 래칫기어(110)에 맞물린다. 이를 위해, 래칫돌기(122)는 정회전의 반대방향인 역회전 방향(B)으로 돌출되어 있어서, 래칫기어(110)의 정회전 시에 정회전 방향(A)으로 개방된 래칫홈(112)에 끼워져 맞물리게 된다. The ratchet protrusion 122 is a portion that receives a rotational force by the ratchet gear 110 during forward rotation, and engages with the ratchet gear 110 during forward rotation. To this end, the ratchet protrusion 122 protrudes in the reverse rotation direction B, which is the opposite direction of the forward rotation, so that the ratchet groove 112 opened in the forward rotation direction A at the forward rotation of the ratchet gear 110. To interlock and engage.

도 5 및 도 6에 도시된 바와 같이, 본 실시예에서는 예각을 가지는 쐐기형상의 래칫홈(112)과 이에 상응하여 형성된 래칫돌기(122)를 제시하고 있다. 그러나, 래칫홈(112)과 래칫돌기(122)는 이에 한정되지는 않으며 회전력 전달이 가능한 다양한 형상을 포함한다.As shown in Figure 5 and Figure 6, the present embodiment presents a wedge-shaped ratchet groove 112 having an acute angle and a ratchet protrusion 122 formed correspondingly. However, the ratchet groove 112 and the ratchet protrusion 122 is not limited thereto and includes various shapes capable of transmitting rotational force.

한편, 래칫기어(110)의 역회전 시에는, 래칫돌기(122)는 래칫기어(110)와 결합되지 않는다. 이를 위해, 래칫돌기(122)는 합성수지와 같은 탄성재질로 이루어진다. 래칫기어(110)의 역회전 시에는 래칫돌기(122)는 래칫홈(112)의 반대방향에서 접근하므로, 래칫홈(112)에 끼워지지 않고 래칫기어(110)의 외주를 따라 이동한다. 이 경우에, 탄성재질로 이루어진 래칫돌기(122)는 래칫기어(110)의 외측으로 변형되어서, 래칫기어(110)의 역방향 시에 래칫돌기(122)가 래칫기어(110)의 외주면을 미끄러지게 된다. 이에 따라, 래칫기어(110)의 역방향 시에 롤러(150)는 래칫기어(110)와의 연결이 해제되어(래칫기어(110)는 공회전), 롤러(150)에 권취된 차양막(10)은 탄성부재(50)의 탄성력에 의해 권출되고 전개될 수 있다.On the other hand, during the reverse rotation of the ratchet gear 110, the ratchet protrusion 122 is not coupled with the ratchet gear (110). To this end, the ratchet protrusion 122 is made of an elastic material such as synthetic resin. When the ratchet gear 110 rotates in reverse, the ratchet protrusion 122 approaches in the opposite direction of the ratchet groove 112 and thus moves along the outer circumference of the ratchet gear 110 without being inserted into the ratchet groove 112. In this case, the ratchet protrusion 122 made of an elastic material is deformed to the outside of the ratchet gear 110 so that the ratchet protrusion 122 slides on the outer circumferential surface of the ratchet gear 110 when the ratchet gear 110 is reversed. do. Accordingly, when the ratchet gear 110 is reversed, the roller 150 is disconnected from the ratchet gear 110 (the ratchet gear 110 is idle), and the sunscreen 10 wound on the roller 150 is elastic. It can be unwound and developed by the elastic force of the member 50.

지지부(124)는 래칫기어(110)의 정회전 시에 변형되는 래칫돌기(122)를 지지하는 부분으로, 래칫돌기(122)의 정회전 방향(A) 측에 인접하여 배치된다. The support part 124 is a part which supports the ratchet protrusion 122 which is deformed at the time of forward rotation of the ratchet gear 110, and is disposed adjacent to the forward direction A of the ratchet protrusion 122.

도 7는 본 고안의 일 실시예에 따른 래칫장치(100)의 래칫돌기(122) 및 지지부(124)를 나타낸 확대도이다.7 is an enlarged view showing the ratchet protrusion 122 and the support part 124 of the ratchet device 100 according to an embodiment of the present invention.

도 7에 나타난 바와 같이, 래칫돌기(122)는 탄성재질로 이루어지므로, 래칫기어(110)의 정회전 시에 래칫돌기(122)는 래칫기어(110)로부터 힘을 받아 외측으로 변형된다. 이 경우에, 래칫돌기(122)의 정회전 방향(A) 측에 인접하여 배치된 지지부(124)는 변형된 래칫돌기(122)를 지지함으로써, 설정된 변형량 이상으로 래칫돌기(122)가 변형되는 것을 방지한다. As shown in FIG. 7, since the ratchet protrusion 122 is made of an elastic material, the ratchet protrusion 122 is deformed to the outside by receiving the force from the ratchet gear 110 during the forward rotation of the ratchet gear 110. In this case, the support portion 124 disposed adjacent to the forward rotation direction A side of the ratchet protrusion 122 supports the deformed ratchet protrusion 122, whereby the ratchet protrusion 122 is deformed by more than a set deformation amount. To prevent them.

다시 말하면, 지지부(124)가 래칫돌기(122)가 변형되는 측에 소정의 좁은 간격을 가지도록 배치됨으로써, 외측으로 변형된 래칫돌기(122)가 외부로 빠지지 않고 지지부(124)에 의해 지지된다. 이에 따라, 래칫돌기(122)가 반복사용이나 급격한 충격으로 인하여 지나치게 변형되어 파손되는 것을 방지할 수 있다. In other words, since the support part 124 is disposed to have a predetermined narrow gap on the side where the ratchet protrusion 122 is deformed, the ratchet protrusion 122 deformed outward is supported by the support part 124 without falling outward. . Accordingly, the ratchet protrusion 122 can be prevented from being excessively deformed and damaged due to repeated use or sudden impact.

여기서, 지지부(124)는 래칫기어(110)의 정회전 시에 래칫돌기(122)가 변형되는 형상에 상응하여 형성된 지지면(124a)을 포함함으로써, 래칫돌기(122)를 보다 안정적으로 지지할 수 있다.Here, the support part 124 includes a support surface 124a formed corresponding to the shape in which the ratchet protrusion 122 is deformed during the forward rotation of the ratchet gear 110, thereby supporting the ratchet protrusion 122 more stably. Can be.

구체적으로, 도 7에 도시된 바와 같이, 본 실시예의 지지면(124a)은 래칫돌기(122)가 변형 각도에 상응하여 경사지게 형성되어 있다. 이에 따라, 변형된 래칫돌기(122)가 지지면(124a)에 안정적으로 면접촉될 수 있다.Specifically, as shown in FIG. 7, the support surface 124a of the present embodiment is formed such that the ratchet protrusion 122 is inclined corresponding to the deformation angle. Accordingly, the deformed ratchet protrusion 122 may be stably in surface contact with the support surface 124a.

한편, 본 실시예의 래칫휠(120)은 래칫돌기(122) 및 지지부(124)를 지탱하기 위하여, 래칫돌기(122) 및 지지부(124)와 결합된 베이스(126)를 추가로 포함할 수 있다. 도 5에 도시된 바와 같이, 본 실시예에서는 래칫돌기(122) 및 지지부(124)가 베이스(126)에 돌출되게 형성되어, 일체로 래칫휠(120)을 형성한다.Meanwhile, the ratchet wheel 120 of the present embodiment may further include a base 126 coupled with the ratchet protrusion 122 and the support 124 to support the ratchet protrusion 122 and the support 124. . As shown in FIG. 5, in the present embodiment, the ratchet protrusion 122 and the support part 124 are formed to protrude from the base 126, thereby integrally forming the ratchet wheel 120.

상술한 바와 같이, 본 실시예의 래칫장치(100)는 래칫돌기(122)의 지나친 변형을 방지하는 지지부(124)를 구비함으로써, 급격한 충격을 받거나 반복 사용되어도 쉽게 파손되지 않는 내구성을 가진다. 이에 따라, 본 실시예의 래칫장치(100)를 구비한 선쉐이드 장치의 내구성도 향상된다.As described above, the ratchet device 100 of the present embodiment includes a support part 124 that prevents excessive deformation of the ratchet protrusion 122, and thus has a durability that does not easily break even when subjected to a sudden impact or repeated use. Thereby, the durability of the sunshade device provided with the ratchet device 100 of this embodiment is also improved.

한편, 본 고안의 일 실시예에서는 선쉐이드 장치에 사용된 래칫장치(100)에 대하여 제시하였으나 이에 한정되지는 않으며, 래칫장치(100)는 일방향 회전이 필요한 다양한 장치에 사용될 수 있다.On the other hand, in one embodiment of the present invention has been presented with respect to the ratchet device 100 used in the sunshade device, but is not limited to this, the ratchet device 100 can be used in a variety of devices that require one-way rotation.
