It is inserted into the fastening ring, but by forming a projection on the inner circumferential surface of the eccentric cam groove of the fastening ring to catch the bottom of the head of the connection bolt, the locking position of the connection bolt is confirmed when the fastening ring is rotated There is no need to forcibly rotate the fastening ring, and also relates to a panel fastening device for furniture, in which the fastening ring is not arbitrarily released in a state in which the connection bolt is coupled with the fastening ring.

일반적으로 사무용 가구는 수평판넬과 수직판넬의 조합으로 이뤄지는데, 이들 수평판넬과 수직판넬은 서로 직교된 상태에서 연결볼트 및 체결링으로 결합된다. 상기 수평판넬에는 저면 또는 윗면에 체결링이 매입되고 수직판넬에는 측면에 연결볼트가 체결된 상태에서 상기 연결볼트의 머리부를 상기 체결링 내부의 캠홈으로 끼워넣고 상기 체결링을 회전시키면 체결링의 편심된 캠홈이 회전되면서 연결볼트를 잡아당겨 수평판넬과 수직판넬이 결합된다.In general, office furniture consists of a combination of horizontal panels and vertical panels, which are joined by connecting bolts and fastening rings at right angles to each other. When the coupling ring is embedded in the bottom or top surface of the horizontal panel, and the connection bolt is fastened to the side of the vertical panel, the head of the connecting bolt is inserted into the cam groove in the coupling ring and the coupling ring is rotated to eccentric the coupling ring. As the cam groove is rotated, the horizontal panel and the vertical panel are combined by pulling the connecting bolts.

그러나 종래에는 상기 체결링의 회전량을 조절할 수 없으므로 연결볼트와의 결합력에 차이가 있었다. 작업자의 숙련된 정도차에 따라 체결링의 회전량이 서로 다르기 때문에 연결볼트의 머리부를 캠홈이 걸고 돌아가는 정도에 차이가 있으므로 수평판넬과 수직판넬을 일정한 체결력으로 결합시킬 수 없으며, 또한 체결이 느슨하면 가구에 손상이 가는 등의 단점이 있었다.However, in the related art, since the amount of rotation of the fastening ring cannot be adjusted, there is a difference in coupling force with the connection bolt. Since the rotation amount of the fastening ring is different depending on the skill of the operator, there is a difference in the degree of turning the cam groove on the head of the connecting bolt. Therefore, the horizontal panel and the vertical panel cannot be combined with a constant fastening force. There was a disadvantage such as damage to the.

본 발명은 종래의 문제점을 감안하여 개발한 것으로서, 본 발명의 목적은 수평판넬과 수직판넬을 직교상태로 체결하기 위하여 상기 수평판넬에는 체결링을 매입하고 상기 수직판넬에는 연결볼트를 고정하여 상기 연결볼트의 머리부가 상기 체결링 내부로 끼워 들어가도록 하되 상기 체결링의 편심된 캠홈의 내주면에 돌기를 형성하여 연결볼트의 머리부 하단의 잘록부가 걸리도록 함으로써, 체결링의 회전시 연결볼트의 걸림위치가 확인되므로 체결링을 무리하게 회전시킬 필요가 없으며, 또한 연결볼트가 체결링과 결합된 상태에서 체결링이 임의로 풀리지 않아 제품의 신뢰성이 향상되는 가구용 판넬 체결장치를 제공함에 있다.The present invention was developed in view of the conventional problems, an object of the present invention is to purchase a fastening ring to the horizontal panel and to fasten the connecting bolt to the vertical panel to fasten the horizontal panel and the vertical panel in an orthogonal state. The head of the bolt is inserted into the fastening ring, but a protrusion is formed on the inner circumferential surface of the eccentric cam groove of the fastening ring so that the convex part of the lower end of the head of the fastening ring is caught, so that the fastening position of the fastening ring is locked. Since it is confirmed that there is no need to forcibly rotate the fastening ring, and also provides a panel fastening device for furniture that improves the reliability of the product is not fastened by the fastening ring arbitrarily loosened in the state that the connection bolt is coupled with the fastening ring.

In addition, the upper portion of the protrusion 13 is formed with an incision 14 on the outer circumferential surface of the fastening ring 10 so that the protrusion 13 is slightly lifted up by the elastic deformation, and the cut-off portion 23 passes over the protrusion 13. To help. Reference numeral 32 is a through part formed in the horizontal panel 30 so that the connecting bolt 20 is fitted to the fastening ring 10.

이처럼 구성된 본 발명 한 실시예는 상기 체결링(10)이 수평판넬(30)의 삽입부(31)에 끼워지고, 수직판넬(40)에는 연결볼트(20)가 체결된 상태에서 도 4에 도시된 바와같이 수평 및 수직판넬(30)(40)을 서로 맞대고 연결볼트(20)의 머리부(21)가 체결링(10) 내부로 끼워들어가도록 한다.One embodiment of the present invention configured as described above is shown in Figure 4 in a state in which the coupling ring 10 is fitted to the insertion portion 31 of the horizontal panel 30, the connection bolt 20 is fastened to the vertical panel 40 As described above, the horizontal and vertical panels 30 and 40 are brought into contact with each other and the head 21 of the connecting bolt 20 is inserted into the fastening ring 10.

이후 드라이버 같은 도구를 십자홈(11)에 끼우고 체결링(10)을 회전시키면 편심된 캠홈(12)에 의해 연결볼트(20)의 머리부(21)가 당겨지면서 수평판넬(30) 및 수직판넬(40)이 견고하게 밀착 고정된다. 상기 체결링(10)은 회전 정점부근에서 돌기(13)가 잘록부(23)를 타고 넘는데, 이때 회전이 정지된다. 상기 돌기(13)는 체결링(10)의 외주면에 형성된 절개부(14)에 의해 위로 약간의 탄성변형이 발생되면서 잘록부(23)가 통과된다.After inserting a tool such as a screwdriver in the cross recess 11 and rotating the fastening ring 10, the head 21 of the connecting bolt 20 is pulled by the eccentric cam groove 12 while the horizontal panel 30 and the vertical Panel 40 is firmly fixed. The fastening ring 10 is a projection 13 near the rotation apex rides over the cut-off portion 23, at which time the rotation is stopped.
