Description

의자 장력 조절장치{Chair Tension Adjuster}Chair Tension Adjuster {Chair Tension Adjuster}

개시되는 내용은 의자 장력 조절장치에 관한 것으로, 더욱 상세하게는 등받이의 장력을 조절하는 의자 장력 조절장치에 관한 것이다. Disclosed content relates to a chair tension adjusting device, and more particularly, to a chair tension adjusting device for adjusting the tension of the backrest.

본 명세서에서 달리 표시되지 않는 한, 이 섹션에 설명되는 내용들은 이 출원의 청구항들에 대한 종래 기술이 아니며, 이 섹션에 포함된다고 하여 종래 기술이라고 인정되는 것은 아니다.Unless otherwise indicated herein, the content described in this section is not prior art to the claims of this application, and inclusion in this section is not admitted to be prior art.

의자는 지면에 지지되는 다리와, 앉을 수 있는 좌판 및 등을 기대는 등받이 그리고 팔을 걸 수 있는 팔걸이를 포함하여 구성된다. The chair includes a leg supported on the ground, a seat on which a seat can be seated, a back on which the back is leaned, and an armrest on which an arm can be hung.

근래에는 보다 기능적인 특성이 개량되어 좌판의 높낮이를 조절하거나 등받이의 각도를 조절하는 등의 기능이 부가되었다. In recent years, more functional characteristics have been improved, and functions such as adjusting the height of the seat plate or the angle of the backrest have been added.

따라서 사용자의 신체적인 특성에 적합하도록 좌판의 높이를 조절하거나 등받이의 각도를 조절하여 보다 유용하게 사용될 수 있다. Therefore, it can be used more usefully by adjusting the height of the seat plate or adjusting the angle of the backrest to suit the physical characteristics of the user.

등받이는 착석한 상태에서 등을 기댔을때 등을 받쳐주는 적당한 장력을 유지할 수 있어야 하고, 사용자마다 각기 개인의 특성에 맞게 조절할 수 있어야 한다.The backrest must be able to maintain the proper tension to support the back when the back is leaned while seated, and each user must be able to adjust according to their individual characteristics.

종래에는 좌판의 하부에 일단이 고정되고, 타단은 등받이에 고정되는 'ㄴ'자 형상의 등받이연결용 프레임이 구비되고, 이 등받이연결용 프레임에 장력조절부를 포함한다. In the related art, one end is fixed to the lower part of the seat plate, and the other end is provided with a frame for connecting a backrest in a'b' shape that is fixed to the backrest, and the frame for connecting the backrest includes a tension adjusting part.

장력조절부는 등받이연결용 프레임을 관통하여 좌판에 결합되는 볼트축과, 상기 볼트축의 하부 외측에 결합되며 일단은 등받이연결용 프레임에 지지되며 타단에는 볼트축에 나사결합된 너트에 고정된다.The tension control unit passes through the frame for connecting the backrest and is coupled to the seat plate, and is coupled to the lower outer side of the bolt shaft, one end is supported by the frame for backrest connection, and the other end is fixed to a nut screwed to the bolt shaft.

너트의 외측에 결합되어 파지할 수 있는 핸들이 외부에 결합된다.A handle that can be gripped by being coupled to the outside of the nut is coupled to the outside.

따라서 핸들을 회전시키면 너트가 회전하게 되고, 너트가 볼트축을 따라 상승 또는 하강하면서 스프링을 압축함으로써 장력의 강약을 조절할 수 있게 된다. Therefore, when the handle is rotated, the nut rotates, and the strength and weakness of the tension can be adjusted by compressing the spring while the nut rises or falls along the bolt axis.

그러나 종래 기술은 핸들이 부피가 크고 외부로 노출되어 있으므로 포장 공정에서 다수개의 등받이연결용 프레임을 적층하기 어려우므로 개별적인 포장을 할 수밖에 없어 포장 비용이 상승하고, 취급하기에도 불편한 단점이 있었다. However, in the prior art, since the handle is bulky and exposed to the outside, it is difficult to stack a plurality of frames for connecting backrests in the packaging process, and thus individual packaging is required, resulting in increased packaging costs and inconvenient handling.

도 1 내지 도 4에 도시된 바와 같이, 실시예에 따른 의자 장력 조절장치는, 의자는 지면에 지지되는 다리(100); 앉을 수 있는 좌판(200); 등을 기대는 등받이(300); 상기 좌판(200)의 하부에 일단이 힌지부(600)로 연결되고, 타단은 등받이에 고정되는 'ㄴ'자 형상의 등받이연결용 프레임(400); 상기 등받이연결용 프레임(400)의 탄성력을 조절하는 장력조절부(A);를 포함하여 구성된다. As shown in Figures 1 to 4, the chair tension adjustment device according to the embodiment, the chair is a leg 100 supported on the ground; Seat plate 200 that can be seated; A backrest 300 leaning on the back; A frame 400 for connecting a backrest having one end connected to the lower part of the seat plate 200 by a hinge part 600 and the other end being fixed to the backrest; It is configured to include a; tension control unit (A) for adjusting the elastic force of the frame 400 for connecting the backrest.

장력조절부(A)는, 좌판(200)의 하부에 결합되며 오목한 요부(520)가 형성되며, 상기 요부(520)에는 통공(522)이 형성된 고정부재(500)를 포함한다. The tension control unit (A) is coupled to the lower portion of the seat plate 200 and has a concave concave portion 520 formed therein, and the concave portion 520 includes a fixing member 500 having a through hole 522 formed therein.

고정부재(500)의 하부 외면에 상기 등받이연결용 프레임(400)의 일단이 축핀(650)으로 힌지 결합되는 힌지부(600)가 형성된다. On the lower outer surface of the fixing member 500, a hinge part 600 is formed at one end of the frame 400 for connecting the backrest by a shaft pin 650.

등받이연결용 프레임(400)을 관통하여 상기 고정부재(500)의 통공(522)에 결합되어 수직하게 형성되는 볼트축(700)과, 볼트축(700)의 하단에 형성되며 공구가 결합되도록 공구홈(712)이 형성된 볼트머리(710)가 형성된다. A bolt shaft 700 formed vertically by passing through the backrest connection frame 400 and coupled to the through hole 522 of the fixing member 500, and a tool formed at the lower end of the bolt shaft 700 to allow the tool to be coupled. A bolt head 710 in which a groove 712 is formed is formed.

볼트축(700)의 외부에 결합되는 스프링(720)이 포함된다. A spring 720 coupled to the outside of the bolt shaft 700 is included.

고정부재(500)는 요부(520)가 형성된 저판부(540)와, 저판부(540)의 양측에 수직의 측벽(542)이 형성되어 형성되고, 힌지부(600)는 저판부(540)를 펀칭시켜 외부에 돌출된 복수의 힌지편체(610)를 축핀(650)이 관통 결합되어 이루어진다. The fixing member 500 is formed by forming a bottom plate portion 540 on which a recess portion 520 is formed, and vertical sidewalls 542 formed on both sides of the bottom plate portion 540, and the hinge portion 600 is a bottom plate portion 540 A plurality of hinge pieces 610 protruding to the outside by punching the shaft pins 650 are penetrated.

고정부재(500)는 수직의 측벽에는 좌판(200)의 하부에 부착되는 플레이트(546)가 양측에 평평하게 형성된다. In the fixing member 500, plates 546 attached to the lower portion of the seat plate 200 are formed flat on both sides on a vertical sidewall.

또한 고정부재(500)는 양측 플레이트(546)에 연결되며 하부로 오목하도록 측벽(542)과 저판부(540)로 이루어진다. In addition, the fixing member 500 is connected to both side plates 546 and includes a side wall 542 and a bottom plate portion 540 to be concave downward.

저판부(540)의 일측에 오목하게 요부(520)가 하향 돌출형성되고, 상기 요부(520)에 통공(522)이 형성된다. 도 4에 도시되는 바와 같이 고정부재(500)의 하향 돌출형성된 요부(520)는 평상시 등받이연결용 프레임(400) 내에 위치된다.A concave portion 520 is formed to protrude downwardly on one side of the bottom plate portion 540, and a through hole 522 is formed in the concave portion 520. As shown in FIG. 4, the concave portion 520 protruding downward of the fixing member 500 is normally located in the frame 400 for connecting the backrest.

그리고 저판부(540)의 타측에는 실린더 결합공(550)이 형성되고, 이 실린더 결합공(550)에 의자의 다리부에 수직하게 결합된 실린더(551)의 로드(552)가 관통 결합된다. Further, a cylinder coupling hole 550 is formed on the other side of the bottom plate portion 540, and the rod 552 of the cylinder 551 vertically coupled to the leg portion of the chair is penetrated through the cylinder coupling hole 550.

고정부재(500)의 측벽(542)의 측면에 관통구멍(543)이 형성되며, 이 관통구멍(543)을 통해 레버축(544)이 결합되며, 레버축(544)의 선단이 로드(552)의 상부에 지지되어 높이조절부가 구비된다.A through hole 543 is formed on the side of the side wall 542 of the fixing member 500, and the lever shaft 544 is coupled through the through hole 543, and the front end of the lever shaft 544 is a rod 552 ) Is supported on the top of the height adjustment unit is provided.

따라서 레버축(544)을 당기면 로드(552)를 누르게 되어 실린더(551)의 로드(552)가 상승 또는 하강함으로써 좌판(200)의 높이가 조절될 수 있다. Therefore, when the lever shaft 544 is pulled, the rod 552 is pressed so that the rod 552 of the cylinder 551 rises or falls, so that the height of the seat plate 200 can be adjusted.

한편 고정부재(500)의 저판부(540)의 하부에는 펀칭 가공에 의해 양측에 대칭되게 힌지편체(610)가 돌출되어 힌지부(600)가 형성된다. Meanwhile, a hinge piece 610 protrudes symmetrically to both sides by punching under the bottom plate portion 540 of the fixing member 500 to form a hinge portion 600.

힌지편체(610)에 등받이연결용 프레임(400)의 일단이 끼워진 후 축핀(650)으로 결합됨으로써 힌지 회전될 수 있도록 하여 등받이연결용 프레임(400)이 힌지부(600)를 기준으로 회전될 수 있고, 이에 따라 등받이(300)의 각도와 적당한 지지력이 조절될 수 있다. After one end of the frame 400 for connecting the backrest is inserted into the hinge piece 610, the hinge can be rotated by being coupled with a shaft pin 650 so that the frame 400 for connecting the backrest can be rotated based on the hinge part 600. And, accordingly, the angle of the backrest 300 and an appropriate support force can be adjusted.

등받이(300)의 적당한 지지력은 장력조절부(A)에 의해 발휘될 수 있다. The proper supporting force of the backrest 300 may be exerted by the tension control unit (A).

즉, 장력조절부(A)를 구성하는 볼트축(700)과 너트(740)의 결합과, 그 사이에 개재된 스프링(720)의 탄성력에 의해 조절될 수 있는 것이다. That is, it can be adjusted by the coupling of the bolt shaft 700 and the nut 740 constituting the tension control unit (A) and the elastic force of the spring 720 interposed therebetween.

일 예에 따르면, 장력조절부(A)는, 볼트축(700)이 등받이연결용 프레임(400)을 관통하고, 저판부(540)의 요부에 형성된 통공(522)을 관통하여 수직하게 결합된 후 그 외측에 스프링(720)이 결합된 다음 와셔(730)와 너트(740)가 볼트축(700)에 결합되어 스프링(720)을 적당한 장력으로 가압하도록 하여 이루어진다. According to an example, the tension adjustment unit (A) is vertically coupled through the bolt shaft 700 through the frame 400 for connecting the backrest, and through the through hole 522 formed in the recess of the bottom plate 540 Then, the spring 720 is coupled to the outside thereof, and then the washer 730 and the nut 740 are coupled to the bolt shaft 700 to press the spring 720 with an appropriate tension.

따라서 스프링(720)의 하단이 요부에 지지되고, 볼트축(700)의 상부에 와셔(730)가 끼움결합되며, 와셔(730)는 스프링(720)의 상단을 지지하도록 결합된다. Therefore, the lower end of the spring 720 is supported on the recess, the washer 730 is fitted to the upper portion of the bolt shaft 700, and the washer 730 is coupled to support the upper end of the spring 720.

그리고 돌출된 볼트축(700)의 상단에 너트(740)가 나사결합되어 와셔(730)에 밀착지지되도록 조립되는 것이다. And the nut 740 is screwed to the upper end of the protruding bolt shaft 700 to be assembled so as to be closely supported by the washer 730.

볼트축(700)의 하단에 등받이연결용 프레임(400)의 두께의 1/2 이하의 두께를 가지는 볼트머리(710)가 형성되고, 이 볼트머리(710)에는 공구홈(712)이 형성된다. 공구홈(712)은 육각렌치와 같은 공구를 끼울 수 있도록 형성되며, 공구를 이용하여 회전시켜서 볼트축(700)을 상승 또는 하강시켜 높이를 조절할 수 있다. A bolt head 710 having a thickness less than 1/2 of the thickness of the frame 400 for connecting the backrest is formed at the lower end of the bolt shaft 700, and a tool groove 712 is formed in the bolt head 710. . The tool groove 712 is formed to fit a tool such as a hexagon wrench, and the height can be adjusted by raising or lowering the bolt shaft 700 by rotating using a tool.

볼트축(700)을 하강시킨다면 스프링(720)은 압축되므로 스프링 탄성이 경직되므로 등받이연결용 프레임(400)의 고정력이 증가되고, 그에 연결된 등받이가 견고하게 고정될 수 있다. If the bolt shaft 700 is lowered, the spring 720 is compressed, so that the spring elasticity is stiff, so that the fixing force of the frame 400 for connecting the backrest is increased, and the backrest connected thereto can be firmly fixed.

이와 반대로 볼트축(700)을 상승시키면 스프링(720)은 신장되므로 스프링 탄성이 유연하게 증가되므로 등받이연결용 프레임(400)의 고정력이 완화되고, 그에 연결된 등받이(300)가 유연하게 회전될 수 있다. Conversely, when the bolt shaft 700 is raised, the spring 720 is elongated, so that the spring elasticity is increased flexibly, the fixing force of the frame 400 for connecting the backrest is relaxed, and the backrest 300 connected thereto can be flexibly rotated. .

비록 바람직한 실시예와 관련하여 설명되어졌지만, 발명의 요지와 범위로부터 벗어남이 없이 다양한 수정 및 변형이 가능한 것은 당업자라면 용이하게 인식할 수 있을 것이며, 이러한 변경 및 수정은 모두 첨부된 청구의 범위에 속함은 자명하다.Although it has been described in connection with the preferred embodiment, it will be easily recognized by those skilled in the art that various modifications and variations are possible without departing from the gist and scope of the invention, and all such changes and modifications fall within the scope of the appended claims. Is self-explanatory.
