Description

등받이의 각도가 조절되는 접이식 의자{Folding Chair with Tilting Back}Folding chair with adjustable angle of backrest {Folding Chair with Tilting Back}

본 발명은 등받이의 각도가 조절되는 접이식 의자에 관한 것으로, 더욱 상세하게는 등받이와 팔걸이 및 지지다리가 일체로 연결되며, 팔걸이와 지지다리의 연결부위에 탄성회동수단을 구비함으로써 착석시 등받이가 일정 각도로 후방으로 회동될 수 있어 안락감을 증대시킬 수 있도록 한 등받이의 각도가 조절되는 접이식 의자에 관한 것이다.The present invention relates to a folding chair in which the angle of the backrest is adjusted, and more particularly, the backrest and the armrest and the support leg are integrally connected, and the backrest is fixed when the seat is provided by the elastic rotation means at the connection portion of the armrest and the support leg. It relates to a folding chair that can be rotated rearward at an angle to adjust the angle of the backrest to increase comfort.

종래 보급되고 있는 사무용 의자는 사용의 편의성을 향상시키기위하여 휴식시에는 의자의 등받이가 뒤로 젖혀지도록 하고, 작업시에는 원위치로 복귀되도록 작동된다. Office chairs that are conventionally spread are operated so that the back of the chair leans back during rest to improve the convenience of use, and returns to its original position during work.

즉, 종래 사무용 의자는 좌판 하부에 등받이의 각도조절장치가 구비되어 있어 등받이를 뒤로 민 상태에서 각도를 고정시킬 수 있다.That is, the conventional office chair is provided with an angle adjusting device of the backrest in the lower part of the seat plate to fix the angle in a state in which the backrest is pushed back.

따라서, 착석자가 원하는 각도에서 고정되도록 하여 편안한 휴식을 취할 수 있게 된다.Therefore, the seated person can be fixed at a desired angle to relax.

그러나 종래 사무용 의자는 등받이의 회동이 착석자의 엉덩이 바로 윗부분에서부터 뒤로 젖혀지게 되므로 착석자는 상체가 전부 젖혀지게 된다.However, in the conventional office chair, since the rotation of the backrest is leaned back from just above the seat of the seat, the seated person is fully tilted.

이러한 자세는 휴식을 취할때는 좋지만 업무를 해야할 경우에는 다시 각도조절장치를 해제시켜 등받이가 수직상태로 복귀되도록 해야 하는 수고를 필요로 한다.This position is good for taking a break, but when you need to work, you need to release the angle adjuster so that the backrest returns to the vertical position.

또한, 등받이를 뒤로 젖히면 요추부분과 등받이가 이격되어 공간이 형성되므로 별도의 요추받침이 필요하게 되므로 이또한 등받이의 구성품이 증가되는 요인이 되며, 비용 상승의 문제점이 발생된다.In addition, when the backrest is folded back, the lumbar region and the backrest are spaced apart to form a space, so a separate lumbar support is required, which also causes an increase in the components of the backrest, and causes a problem of cost increase.

이와 같이 구성된 본 발명의 작동관계에 대해 도 4 및 도 5를 참조하여 설명하면 다음과 같다.Referring to Figures 4 and 5 with respect to the operating relationship of the present invention configured as described above are as follows.

도 4에 나타낸 바와 같이, 좌판(100)을 전개시켜 전방 및 후방지지다리(32,34)가 적정한 사잇각으로 벌어지게 한 후 좌판(100)이 수평이 되게 한 다음 착석한다.As shown in FIG. 4, the seat plate 100 is developed to allow the front and rear support legs 32 and 34 to be opened at appropriate angles, and the seat plate 100 is then horizontally seated.

이후 도 5에 나타낸 바와 같이, 착석 후 등받이(2)에 기대면 후방으로 젖혀지게 되고, 이에 연동되어 팔걸이(4)가 회전되며, 그에 종동되어 원판부재(8) 및 걸림단턱(82)이 회전된다.Then, as shown in Figure 5, after seated leaning on the backrest 2 is folded back, the armrest 4 is rotated in conjunction with this, and the disc member 8 and the locking step 82 is rotated to follow do.

이때 원판부재(8)와 팔걸이(4) 사이에 존재하는 작동편부(84)가 작동홈(52) 내에서 후방으로 이동하게 된다.At this time, the operation piece 84 existing between the disc member 8 and the armrest 4 is moved to the rear in the operation groove (52).

이에 종동되어 원판부재(8)가 시계방향으로 회전되며, 그 걸림단턱(82)이 토션스프링(7)의 타단부를 밀어 오므리게 된다.Following this, the disc member 8 is rotated in the clockwise direction, and the locking end jaw 82 pushes the other end of the torsion spring 7 together.

이때 토션스프링(7)은 오므려진 상태에서 원래의 상태로 복원하려는 반발력이 발생하게 된다.At this time, the torsion spring 7 generates a repulsive force to restore the original state from the pinched state.

따라서, 착석자가 등받이(2)에서 등을 떼면 토션스프링(7)의 복원 반발력에 의해 원판부재(8) 및 팔걸이(4), 그리고 그에 종속된 등받이(2)가 원래의 수직된 상태로 복귀하게 된다. Therefore, when the seated person lifts his back from the backrest 2, the disc member 8 and the armrest 4 and the backrest 2 subordinate to the back member 2 are returned to their original vertical state by the restoring repulsion force of the torsion spring 7. do.
