본 고안은 의자용 머리받침대의 높이 조절 구조에 관한 것으로, 보다 상세하게는 머리받침대를 간단하고 용이하게 상/하 이동시켜 고정할 수 있도록 하는 의자용 머리받침대의 높이 조절 구조에 관한 것이다.The present invention relates to a height adjustment structure of the head restraint for a chair, and more particularly, to a height adjustment structure of the head restraint for a chair to be fixed by moving the head rest up and down simply and easily.

종래의 의자는 좌석부, 등받이부와 팔걸이부 등으로 구성되어지며, 상기한 등받이부의 상단에는 사용자가 편하게 쉴 수 있도록 머리받침대가 선택적으로 더 설치된다.Conventional chair is composed of a seat, back and armrests, etc., the headrest is optionally further installed on the top of the backrest so that the user can relax comfortably.

이러한, 머리받침대는 통상 사용자의 신체조건에 맞도록 상/하 높이 조절이 가능하도록 설치되는데, 종래에는 실용신안등록 제383047호와 같이 머리받침대의 하부돌출부에 다수의 구멍을 천공하고, 볼트를 상기한 구멍과 등받이를 관통시켜 높이를 조절하였다.Such, the head restraint is usually installed to be able to adjust the upper / lower height to suit the user's physical conditions, conventionally registered as a utility model No. 383047, a plurality of holes in the lower protrusion of the head restraint, the bolt The height was adjusted by passing through one hole and backrest.

그러나 이러한 볼트를 사용한 높이 조절구조는 사용자가 볼트를 풀었다 조여야 하므로 사용이 번거로운 문제점이 있었다.However, the height adjustment structure using the bolt has a problem that it is cumbersome to use because the user must loosen and tighten the bolt.

본 고안은 상기한 바와 같은 문제점을 해결하기 위한 것으로, 머리받침대를 레버를 조작하는 간단한 동작으로 높이조절가능하도록 하는 의자용 머리받침대의 높이 조절 구조를 제공하는 데 있다.The present invention is to solve the problems as described above, to provide a height adjustment structure of the head restraint for the chair to make the height adjustable by the simple operation of operating the lever head.

상기한 목적을 달성하기 위한 본 고안의 특징은 머리받침대의 하부로 돌출부를 형성하고, 상기한 돌출부의 외주면에는 상/하로 요철부를 형성하며, 등받이 프레임에는 상기한 돌출부가 삽입되는 삽입홈이 형성되고, 상기한 삽입홈이 형성된 위치에는 삽입공이 형성되며, 일측종단이 편심캠모양으로 형성된 레버가 상기한 삽입공과 대응되는 위치에 힌지결합되어 레버가 등받이 프레임과 일정각도 벌어지도록 조작되면 머리받침대가 상하이동되고 레버가 등받이 프레임과 수평하게 조작되면 편심캠모양의 노즈가 상기한 요철부와 맞물려서 높이가 고정되도록 한 의자용 머리받침대의 높이 조절 구조에 있다.Features of the present invention for achieving the above object is to form a protrusion to the bottom of the head restraint, the outer circumferential surface of the protrusion to form an uneven portion up and down, the back frame is formed with the insertion groove is inserted into the protrusion The insertion groove is formed at the position where the insertion groove is formed, and the one end of the head is hinged to a position corresponding to the insertion hole formed in an eccentric cam shape so that the lever is operated to open a predetermined angle with the backrest frame, and the head restraints up and down. When moved and the lever is operated horizontally with the backrest frame is the height adjustment structure of the headrest for the chair so that the height of the eccentric cam-shaped engagement with the above-mentioned convex portion is fixed.

이상과 같이 구성된 본 고안의 실시예를 하기에서 첨부된 도면을 참조하여 보다 상세하게 살펴본다.An embodiment of the present invention configured as described above will be described in more detail with reference to the accompanying drawings.

도 1은 본 고안에 따른 의자용 머리받침대의 높이 조절 구조를 나타내는 측단면도이고, 도 2a및 도 2b는 의자용 머리받침대의 사용예를 나타내는 확대단면도이다.1 is a side cross-sectional view showing a height adjustment structure of the chair headrest according to the present invention, Figures 2a and 2b is an enlarged cross-sectional view showing an example of the use of the chair headrest.

본 고안에 따른 의자용 머리받침대의 높이 조절 구조는 등받이 프레임(10)의 상부에 형성된 삽입홈(12)의 내부로 머리받침대(20)의 하부 돌출부(22)가 삽입되어 편심캠모양으로 형성되어 등받이 프레임(10)에 힌지 결합된 레버(30)와 돌출부(22)에 형성된 요철부(22a)의 맞물림 상태에 따라 머리받침대(20)가 상하 높이 조절 되도록 한 것이다.The height adjustment structure of the headrest for chair according to the present invention is formed in the shape of the eccentric cam by inserting the lower protrusion 22 of the headrest 20 into the interior of the insertion groove 12 formed on the top of the backrest frame 10 The head restraint 20 is adjusted up and down according to the engagement state of the lever 30 coupled to the backrest frame 10 and the uneven portion 22a formed in the protrusion 22.

상기한 구성에서, 머리받침대(20)는 상/하 회전이 가능하도록 설치되고, 그 하부로는 외향면에 상하로 요철부(22a)가 형성된 돌출부(22)가 일정길이 돌출형성된다.In the above configuration, the head restraint 20 is installed to be able to rotate up and down, and the protrusion 22 having a concave-convex portion 22a is formed on the outward surface up and down at a predetermined length thereof.

그리고 상기한 등받이 프레임(10)의 상부 중심에는 삽입홈(12)이 형성되고, 상기한 삽입홈(12)을 형성하는 등받이 프레임(10)의 후면에는 삽입공(24)이 형성되며, 상기한 삽입공(24)의 양측부에는 대응되는 고정프레임(26)이 형성되어, 상기한 고정프레임(26)에 레버(30)가 힌지결합된다.An insertion groove 12 is formed in the upper center of the backrest frame 10, and an insertion hole 24 is formed in the rear surface of the backrest frame 10 forming the insertion groove 12. A corresponding fixing frame 26 is formed at both sides of the insertion hole 24, and the lever 30 is hinged to the fixing frame 26.

그리고 상기한 레버(30)는 삽입공(24)으로 돌출되는 부분이 편심캠 모양으로 형성되는데, 도 2a에 나타내는 바와 같이 레버(30)가 등받이 프레임(10)과 수평한 위치가 될 때에는 상기한 편심캠모양의 종단에 형성된 노즈(nose;32)가 요철부(22a)와 맞물리게 되고, 도 2b에 나타내는 바와 같이 레버(30)가 등받이 프레임(10)과 수직한 위치가 될 때에는 편심캠모양의 종단에 형성된 노즈가 위치이동되어 요철부(22a)와 노즈(32)의 맞물림 상태가 해제되므로 머리받침대(20)는 상하 높이 조절이 가능하게 된다.In addition, the lever 30 is formed in the shape of the eccentric cam is projected into the insertion hole 24, as shown in Figure 2a when the lever 30 is in a horizontal position with the backrest frame 10 as described above The nose 32 formed at the end of the eccentric cam shape is engaged with the uneven portion 22a, and as shown in FIG. 2B, when the lever 30 is perpendicular to the backrest frame 10, the eccentric cam shape Since the nose formed at the end is moved, the engagement of the uneven portion 22a and the nose 32 is released, so that the head restraint 20 can be adjusted up and down.

따라서, 사용자는 머리받침대(20)의 높이를 조절하고자 할 경우 상기한 레버(30)를 등받이 프레임(10)과 수직하도록 조작한 후 머리받침대(20)를 원하는 위치로 위치이동시키고, 이동된 위치에 고정시키고자 할 경우에는 상기한 레버(30)를 등받이 프레임(10)과 수평하도록 조작하면 된다.Therefore, when the user wants to adjust the height of the head restraint 20, the user operates the lever 30 to be perpendicular to the backrest frame 10, and then moves the head restraint 20 to a desired position and moves the position. In order to fix the pressure, the lever 30 may be operated to be horizontal with the back frame 10.

따라서, 본 고안에 의하면 머리받침대의 높이조절작업이 매우 용이하여 사용상의 편의성이 향상되는 효과가 있다.Therefore, according to the present invention, it is very easy to adjust the height of the head restraint has an effect of improving convenience in use.
