The present invention relates to a sitting posture detection device and a control method thereof, and more particularly, to measure the inclination angle of a seat in a chair having a left seat and a right seat that independently support the left and right pelvis of the user, respectively. The present invention relates to a sitting posture detecting apparatus and a method of controlling the same.
최근 현대인들은 직장에서의 업무, 가정에서의 컴퓨터 작업, 공부 등으로 인해 직장 및 가정에서 의자에 앉아 생활하는 시간이 많다. 오랜 시간 동안 계속해서 의자에 앉아있는 자세가 바르지 못한 경우 척추나 골반 등의 골격계에 질환을 야기하거나 또는 골격계 외의 내부 질환을 야기할 수 있다.Recently, modern people have a lot of time sitting in chairs at work and at home due to work at home, computer work at home, and study. Incorrect posture of sitting on a chair for a long time may cause diseases of the skeletal system such as the spine or pelvis or internal diseases other than the skeletal system.
따라서 본 출원인은 의자를 사용하는 사용자들의 신체적인 조건을 고려하여 골반의 간격에 맞게 한 쌍의 좌대 간격을 일정한 거리로 설정하여 중심부에서 상하로 이동 가능하게 하여 사용자의 골반 건강을 도모할 수 있는 골반 보호용 의자를 연구 개발하여 특허 등록을 하였다. Accordingly, the present applicant sets a pair of base seat intervals to a certain distance in consideration of the physical conditions of the users using the chair to move up and down from the center to promote the pelvic health of the user. We have researched and developed a protective chair and registered a patent.
도 1 내지 도 3에 도시된 바와 같이, 골반 보호용 의자는, 베이스플레이트(11)의 상방 양단에 대칭으로 배치되는 적어도 한 쌍의 베이스힌지(13)를 가지며, 미리 설정된 높이로 유지되는 고정부(60)의 상부에 장착되는 베이스(10)와, 베이스힌지(13)에 힌지 결합되는 받침대힌지(23)가 하방의 일측에 형성되어 있는 적어도 한 쌍의 좌대받침대(20)와, 베이스(10)와 좌대받침대(20)가 힌지 결합되는 위치에 설치되어, 베이스(10)에 대하여 좌대받침대(20)를 탄성적으로 유지시켜 주는 스프링(30) 및 좌대받침대(20)에 대응되도록 설치되는 좌대(50)를 포함하는 구성을 갖는다. 1 to 3, the pelvic protective chair has at least a pair of base hinges 13 arranged symmetrically on both ends of the base plate 11, and a fixed portion maintained at a predetermined height ( Base 10 is mounted on the upper portion of the 60, pedestal hinge 23 hinged to the base hinge 13 is formed on one side of the at least one pair of seat pedestal 20, the base 10 And the pedestal 20 is installed at a position where the pedestal hinge 20 is coupled to the hinge, and the pedestal is installed so as to correspond to the spring 30 and the pedestal base 20 to elastically maintain the pedestal base 20 relative to the base ( 50).
여기서, 베이스힌지(13)에는 힌지 결합을 위한 제1힌지결합공(13a)이 형성되어 있고, 베이스(10)의 중앙 부분에는 고정부(60)와의 결합을 위한 결합부(11a)가 형성되어 있으며, 결합부(11a)에는 고정부(60)와의 나사 결합을 위한 베이스결합공(11b)이 형성되어 있다. Here, the first hinge coupling hole 13a for hinge coupling is formed in the base hinge 13, and the coupling portion 11a for coupling with the fixing part 60 is formed in the center portion of the base 10. The coupling portion 11a has a base coupling hole 11b for screwing with the fixing portion 60.
좌대받침대(20)에는 스프링(30)의 일단이 끼움 결합되는 스프링결합부(21a)가 형성되고, 그 일측에는 좌대(50)를 결합시키기 위한 좌대결합공(21b)이 형성되어 있다. The seat pedestal 20 is formed with a spring coupling portion 21a to which one end of the spring 30 is fitted, and a seat coupling hole 21b for coupling the seat 50 to one side thereof is formed.
좌대받침대(20)의 받침대힌지(23)는 베이스(10)의 측단에 접촉되어 베이스힌지(13)의 제1힌지결합공(13a)에 힌지 결합되는 제2힌지결합공(23a)이 형성되어 있다. The pedestal hinge 23 of the pedestal base 20 is in contact with the side end of the base 10 to form a second hinge coupling hole 23a hinged to the first hinge coupling hole 13a of the base hinge 13. have.
스프링(30)은 그 일측이 베이스(10)의 상측면에 접촉됨과 동시에, 타측은 좌대받침대(20)의 하측면에 접촉되도록 만곡된 형태를 갖는 판스프링으로 구성된다. The spring 30 is composed of a leaf spring having a curved shape so that one side thereof is in contact with the upper surface of the base 10 and the other side is in contact with the lower surface of the seat rest 20.
이때, 베이스(10)의 상측면에 접촉되는 판스프링의 단부는 상향 만곡 가공된 만곡부(35)를 더 포함하고, 만곡부(35)는 좌대(50)가 과도하게 하방으로 이동할 때 발생하는 충격을 완충하는 역할을 하게 된다. At this time, the end portion of the leaf spring in contact with the upper surface of the base 10 further includes an upward curved curved portion 35, the curved portion 35 is a shock generated when the base 50 is moved excessively downward It will act as a buffer.
그리고 좌대받침대(20)의 하측면에 접촉되는 판스프링의 단부는 좌대받침대(20)에 고정된다. And the end of the leaf spring in contact with the lower side of the seat rest 20 is fixed to the seat rest 20.
이와 같은 구성을 갖는 골반 보호용 의자는, 주요 구성요소들이 도 3에 도시된 바와 같이 베이스(10)와 좌대받침대(20)에 각각 베이스힌지(13)와 받침대힌지(23)를 용접으로 고정한 후, 베이스힌지(13)와 받침대힌지(23)를 상호 맞물린 상태에서 힌지볼트(40)를 이용하여 힌지 결합시키게 된다. Pelvic protective chair having such a configuration, after the main components are fixed to the base hinge 13 and the pedestal hinge 23 to the base 10 and the pedestal 20, respectively, as shown in Figure 3, In the state in which the base hinge 13 and the pedestal hinge 23 are engaged with each other, the hinge bolt 40 is used for hinge coupling.
이때, 베이스힌지(13)와 받침대힌지(23)를 상호 맞물리는 과정에서 힌지볼트(40)를 체결하기 전에 스프링(30)을 베이스(10)와 좌대받침대(20) 사이에 강제로 압착하여 장착한 후에 힌지볼트(40)를 체결한다. At this time, the spring 30 is forcibly compressed between the base 10 and the pedestal 20 before the hinge bolt 40 is engaged in the process of engaging the base hinge 13 and the pedestal hinge 23 with each other. After tightening the hinge bolt (40).
그리고 좌대받침대(20) 위에 좌대(50)를 좌대 볼트(55)로 고정시킨다. Then, the seat 50 is fixed to the seat pedestal 20 with a seat bolt 55.
그런 다음, 필요에 따라 캐스터(66)가 장착된 스탠드(65)에 결합되어 있는 고정부(60)에 베이스(10)를 결합시키고, 베이스(10) 또는 고정부(60)에 팔걸이(75)와 등받이(70)를 결합시킴으로써, 골반 보호용 의자가 완성된다. Then, if necessary, the base 10 is coupled to the fixing part 60 coupled to the stand 65 on which the caster 66 is mounted, and the armrest 75 to the base 10 or the fixing part 60. By combining the back and the back 70, the pelvic protection chair is completed.
따라서 사용자가 좌대(50)에 앉으면, 도 2의 2점 쇄선으로 나타낸 사용자의 골반에 의하여 가해지는 무게에 의하여 좌대(50)가 베이스힌지(13) 및 받침대힌지(23)를 중심으로 중앙 쪽에서 하향 이동하기 때문에 골반의 양측면에서 중심쪽으로 밀어주는 힘(도 2의 화살표 참조)이 발생되어 사용자의 골반을 보호해 주게 된다.Therefore, when the user sits on the seat 50, the seat 50 is lowered from the center with respect to the base hinge 13 and the pedestal hinge 23 by the weight applied by the user's pelvis shown by the two-dot chain line of FIG. Because of the movement, a force (see an arrow in FIG. 2) is pushed from both sides of the pelvis toward the center to protect the user's pelvis.
