블라인드의 복원스프링 탄력 조절장치{Spring elasticity adjuster of blinds}[0001] Spring elasticity adjuster of blinds [

본 발명은 블라인드의 권취봉에 블라인드지가 완전히 감긴 상태에서도 상당한 탄력이 권취봉에 작용되도록 설정하는 것에 관한 것으로, 보다 상세하게는 블라인드의 권취봉에 가변적인 회전력이 작용하도록 권취봉 내면에 장치되는 복원스프링 일측을 임의로 회전시키면 복원스프링이 압축되면서 일정한 탄력이 형성되어 블라인드지가 권취봉에 다 감겨지더라도 상기 압축에 의한 탄력이 권취봉에 작용하여 상당한 회전력이 작용할 뿐 아니라 블라인드지가 상승하면서 권취봉에 완전히 감겨질 때 압축된 복원 스프링이 복원되는 탄력에 의해 쉽게 권취봉이 회전되면서 블라인드지가 감겨지도록 되는 블라인드의 복원스프링 탄력 조절장치에 관한 것이다.The present invention relates to a technique for setting a considerable elastic force to be applied to a winding rod even when the blind strip is completely wound around the winding rod of the blind. More specifically, If the blind spindle is wrapped around the wind-up stick, the elastic force by the compression acts on the wind-up bar and a considerable rotational force is exerted. In addition, the blind spindle is raised and the wind- The present invention relates to a restoring spring elasticity adjusting device for a blind, in which a blind spiral is wound while a wind-up stick is easily rotated by an elastic force of restoring a compressed restoring spring when wound.

일반적으로, 블라인드는 천정이나 벽에 고정되도록 되는 프레임 하부에 권취봉이 구동장치에 의해 회전 구동 가능하게 장치되고, 상기 구동장치에 구동 줄이 구동 가능하게 연결되며, 권취봉 외주면에 블라인드지가 감겨 지도록 구비되어, 구동 줄을 당기는 방향에 따라 블라인드지가 권취봉에 감기거나 감겼던 블라인드지가 풀리게 된다.Generally, the blind is installed in a lower part of a frame to be fixed to a ceiling or a wall so that a wind-up rod can be rotatably driven by a driving device, a drive wire is drivably connected to the driving device, and a blind paper is wound around the wind- The blind paper wound around the winding rod or the blind paper wound around the blind spindle is released according to the direction of pulling the drive string.

이러한 종래 블라인드는 구동 줄을 회전시키면 권취봉이 회전되면서 권취봉에 감겨진 블라인드지가 풀려 하부로 펼쳐지게 되며, 상기 하부로 펼쳐진 블라인드지 하단부에는 소정 하중을 갖는 중량체가 형성되어 블라인드지가 하부로 반듯하게 펼쳐지도록 된다.In this conventional blind, when the driving rope is rotated, the wind-up bar is rotated, and the blind paper wound around the wind-up bar is unfolded to be spread downward, and a weight having a predetermined load is formed at the lower end of the blind spine lowered to lower the blind paper do.

구동 줄을 반대로 회전시키면 권취봉에서 풀린 블라인드지가 권취봉이 반대로 회전되면서 블라인드지가 권취봉에 감겨지게 된다.When the drive string is rotated in the opposite direction, the blind spindle unwinded from the wind-up rod is rotated in the opposite direction, and the blind spindle is wound around the wind-up rod.

그러나 상기 하부로 펼쳐진 블라인드지의 길이와 중량체의 무게에 의해 권취봉에 쉽게 감겨지지 못하는 문제점이 있었다.However, there has been a problem that the length of the blind paper spread downward and the weight of the weight can not be easily wound on the winding rods.

상기한 문제점을 해결하기 위해 먼저 블라인드지가 감겨지거나 풀리도록 형성되는 권취봉 내면에 복원스프링을 장치하여 상기 복원스프링의 탄력이 권취봉에 작용되도록 한 후 블라인드지가 하강 되도록 구동 줄을 회전시키면 권취봉이 회전되면서 블라인드지가 하강되어 펼쳐진 상태가 되고, 이때 복원스프링은 권취봉의 회전으로 인해 압축된 상태가 된다.In order to solve the above-described problem, first, a restoring spring is installed on the inner surface of the winding rod formed to wind or unwind the blind paper so that the elastic force of the restoring spring is applied to the winding rod, and then the driving rod is rotated so that the blind paper is lowered. The blind paper is lowered and unfolded. At this time, the restoring spring is compressed due to the rotation of the winding rod.

반대로 블라인드지가 상승 되도록 구동 줄을 회전시키면 압축된 복원스프링이 복원되는 반발력에 의해 권취봉이 쉽게 회전되고 이로 인해 블라인드지가 쉽게 권취봉에 감기게 된다.On the other hand, if the driving rod is rotated so that the blind paper is raised, the winding rod can be easily rotated by the repulsive force that the compressed restoring spring is restored, and the blind paper is easily wound around the winding rod.

그러나 상기와 같이 복원스프링의 탄력에 의해 블라인드지가 권취봉에 쉽게 감겨지도록 하는 장치는 먼저 복원스프링의 탄력을 조절하는 조작이 불편할 뿐 아니라 장치의 구성이 복잡하여 복원스프링의 탄력을 조절하는 장치의 제작단가가 높아지는 문제점이 있었다.However, since the apparatus for easily winding the blind spindle on the winding rod by the elastic force of the restoring spring as described above is inconvenient in the first operation for adjusting the elasticity of the restoring spring, There is a problem that the unit price is increased.

또한 스프링고정구(38)는 스프링지지구(36)로 삽입되어 걸림홈(i)에 탄력적으로 체결되는 탄성 결착돌기(m)들이 구비되고, 안쪽 중간 동심원상으로 턱을 두고 돌출부(h)가 형성되어 복원스프링(35) 내부에 구비되는 지지축(39)의 끝이 돌출부(h)에 삽입되도록 된다.The spring fixture 38 is provided with elastic fixation protrusions m inserted into the spring retainer 36 and elastically fastened to the retaining grooves i so that the protrusions h are formed on the inner intermediate concentric circle So that the end of the support shaft 39 provided inside the restoring spring 35 is inserted into the projection h.

즉, 스프링고정구(38)의 탄성 결착돌기(m)들이 스프링지지구(36)의 걸림홈(i)에 탄력적으로 체결되어 복원스프링(35)이 고정용키(k)와 절개부(j) 사이에 견고하게 밀착된다.That is to say, the elastic fixing projections m of the spring fixing holes 38 are elastically fastened to the locking grooves i of the spring retainer 36 so that the restoring springs 35 are inserted between the fixed keys k and the cut portions j As shown in FIG.

이와 같이 구성되는 본 발명은 구동 줄(3)을 당기면 권취봉 구동장치(10)의 구동판과 함께 권취봉(30)이 회전되어 권취봉(30)에 감겼던 블라인드지(40)가 풀리며 하강하게 되는데, 이때 권취봉(30) 일측 내부에 맞물린 텐션조절구(33)와 스프링연결부(34)의 일단부도 함께 회전되어 복원스프링(35)이 압축되면서 회전 반발력이 증가하게 된다.When the drive rope 3 is pulled in this manner, the winder 30 is rotated together with the drive plate of the winder rod driving device 10, so that the blind paper 40 wound on the winder rod 30 is released, At this time, one end of the spring connection portion 34 and the tension adjuster 33 engaged with the inside of the winding rod 30 are also rotated together to compress the restoring spring 35, thereby increasing the rotational repulsive force.

한편, 구동 줄(3)을 반대 방향으로 당기면 구동장치(10)의 구동판이 권취봉(30)을 반대 방향으로 회전시키게 되어 풀렸던 블라인드지(40)가 권취봉(30) 외주면에 감기게 되는데, 이때 권선 방향으로 압축되었던 복원스프링(35)의 반발력이 구동장치(10)에 회전 구동력으로 작용하여 필요 구동력이 감소하도록 하며, 블라인드지(40)가 권취봉(30)에 다 감긴 상태에서도 복원스프링(35)의 탄력적인 구동력이 잔류하여 블라인드지(40)의 하중에 의한 권취봉(30) 회전을 억제하게 된다.On the other hand, when the drive rope 3 is pulled in the opposite direction, the drive plate of the drive unit 10 rotates the take-up rods 30 in the opposite direction so that the unwound blind paper 40 is wound on the outer circumferential surface of the take- The restoring force of the restoring spring 35 which has been compressed in the winding direction acts on the driving device 10 as a rotational driving force so that the necessary driving force is reduced. When the blind paper 40 is wound around the winding rod 30 The resilient driving force of the spring 35 remains and the rotation of the winding rod 30 due to the load of the blind paper 40 is suppressed.

이러한 본 발명은 브라켓(4)의 조작구멍(a)을 통해 드라이버와 같은 도구를 사용해 회전지지대(20) 내부의 작동부재(22)를 밀면 도 6과 같이 스프링지지구(36)가 복원스프링(35)을 일측으로 밀면서 고정부재(21)의 스플라인 구멍에서 빠져나오게 되며, 작동부재(22)를 적당히 회전시킨 상태로 놓으면 압축스프링(23)의 반발력에 의해 원래 위치로 돌아가게 되고 스프링지지구(36)의 기어부가 고정부재(21)의 스플라인 구멍 안에 다시 체결되게 된다.6, when the operation member 22 inside the rotary support 20 is pushed through an operation hole a of the bracket 4 using a tool such as a screwdriver, The spring member 35 is returned to its original position by the repulsive force of the compression spring 23 when the operating member 22 is properly rotated, 36 are fastened again in the spline hole of the fastening member 21.

이때 복원스프링(35)의 타측부는 텐션조절구(33)에 고정된 상태가 된다.At this time, the other side of the restoring spring 35 is fixed to the tension adjuster 33.

즉, 본 발명은 블라인드 설치시 블라인드지(40)가 권취봉(30)에 완전히 감겨진 초기상태에서 간단한 조작으로 고정되어 있는 복원스프링(35) 일측을 회전시켜서 회전 방향으로 탄력적인 스프링의 일정 반발력이 구동장치(10) 및 권취봉(30)에 작용되도록 설정한다.That is, according to the present invention, in the initial state where the blind paper 40 is completely wound on the wind-up rod 30 when the blind is installed, one side of the restoring spring 35 fixed by a simple operation is rotated to generate a certain repulsive force Is set to act on the driving device (10) and the winding rod (30).

상기와 같이 블라인드 설치시 블라인드지(40)가 권취봉(30)에 완전히 감겨진 초기상태에서 복원스프링(35)을 회전시켜 회전 방향으로 탄력적인 반발력을 한 번만 형성시키면 블라인드지(40)를 감아 올릴 때 항상 최상부에서 권취봉(30)에 탄력적인 반발력이 작용하여 쉽게 권취봉(30)에 블라인드지(40)가 감기게 될 뿐 아니라 권취봉(30)에 블라인드지(40)가 완전히 감긴 상태로 유지되게 된다.When the blind paper 40 is completely wound around the wind-up rod 30 during the blind installation as described above, when the restoring spring 35 is rotated in the initial state to form a resilient repelling force only once in the rotating direction, the blind paper 40 is wound The blind spindle 40 is wound on the wind-up stick 30 easily and the blind spindle 40 is completely wound on the wind-up bar 30 by applying a resilient repulsive force to the wind- .

한편, 권취봉지지구(31)는 회전지지대(20)의 플랜지부 외주면과 고정부재(21)의 외주면에서 원활하게 회전이 가능하도록 내주면이 턱을 두고 형성되고, 외주면에 권취봉(30) 내주면이 기밀하게 끼워져 연동할 수 있도록 탄성 돌출판들이 형성된다.On the other hand, the winding-up seal zone 31 is formed with an inner circumferential surface so as to be smoothly rotatable from the outer circumferential surface of the flange portion of the rotary support 20 and the outer circumferential surface of the fixing member 21, and the inner circumferential surface of the winding rod 30 Elastic stone presses are formed so that they can be tightly fitted and interlocked.

여기에서 상기 권취봉지지구(31) 내주면에 형성된 턱에 의해 고정부재(21)의 플랜지 부분이 걸려 축 방향 이동이 제한되게 된다.The flange portion of the fixing member 21 is caught by the jaw formed on the inner circumferential surface of the winding-up bag seal 31 to restrict axial movement.
