본 고안은 일반 가정에서, 통상적으로 사용하는 교자상의 절첩식 상다리를 펼친 상태와 접은 상태에서 보다 간편하고 용이하게 상다리를 고정지지시킬 수 있는 절첩식 상다리의 고정장치에 관한 것으로, 특히, 상의 상면판 하부 테두리에 설치되는 통상적인 측판의 내측면에 괘지공과 괘지요홈을 갖는 괘지편과 함께 상다리를 축착하고, 상다리의 회전 축봉 직하부에 천공한 관통공으로, 괘지봉을 탄설한 고정장치를 관통되게 삽설하여 괘지봉을 상다리로부터 상기 괘지편의 괘지공과 괘지요홈으로 간단히 출몰입 작동시켜서 상다리를 펼침과 접은 상태에서 견고하게 고정시킬 수 있도록 구성하므로서, 상다리의 유동과 소음이 전혀 없고, 절첩고정을 용이하게하여 교자상의 운반 및 보관과 그 사용을 매우 편리하게 한 것이다.The present invention relates to a device for fixing a folded upper leg that can easily and easily hold the upper leg in the extended state and the folded state on the gyoza commonly used in the general home, in particular, the top plate The upper leg is condensed together with the hanging piece with the hanging hole and the hanging groove on the inner side of the conventional side plate installed at the lower rim, and the through-hole drilled directly under the rotating shaft of the upper leg to pass through the fixing device with the hanging rod. By inserting and inserting the hanging rod from the upper leg to the hanging hole and the hanging groove of the hanging piece, it is configured so that the upper leg can be firmly fixed in the extended and folded state, so that there is no flow and noise of the upper leg at all, and easy folding fixation. It is very convenient to carry and store on the gyoza and its use.

종래에도 교자상의 상다리 고정장치가 무수히 안출된 바 있으며, 그 일예로서 2개의 상다리를 한조가 되게 지지대로 연결하고, 상면판의 저면 중앙에 보강대를 설치하여 회동요홈을 형성함과 동시에 이와 대향되는 위치의 측판 내측으로 회동요부를 형성한 후, 이들 사이에 삼각판상의 회동고정편을 축착시킨 상다리의 고정장치가 있는 바, 이는 회동고정편을 회전지지시켜 상다리를 세워 고정시킬 수는 있으나, 상다리를 접었을 경우 이를 고정시켜주는 별다른 장치가 없어, 교자상의 운반 및 보관시 상다리가 유동될 뿐 아니라 소음이 발생하게 되는 사용상의 불편한 문제점과 아울러 회동고정편의 장기 사용에 따른 마모와 유격발생으로 상다리를 긴밀한 고정상태로 유지시켜 줄 수 없는 결점이 있었으며, 또한, 상면판 저면에 회동고정편을 축착시켜 주기위한 보강대나 상다리에 연결시킨 지지대 및 회동고정편 등의 복잡한 구조로 인하여 교자상의 중량을 가중시켜 주게되고, 이러한 조악한 구조에 의하여 제작공정의 곤란성과 많은 자재의 소모로 단가상승 및 작업시 제품불량이 증가하여 생산성마저 저하되는 등의 제폐단이 있는 것이었다.In the past, there are numerous grating-shaped upper leg fixing devices, and as an example, two upper legs are connected together as a support, and a reinforcing bar is installed in the center of the bottom surface of the upper plate to form a turning groove and face the same. After forming the pivot to the inside of the side plate of the position, there is a fixing device of the upper leg in which the rotating fixing piece on the triangular plate condensed therebetween, which can be fixed by standing the upper leg by rotating the rotating fixing piece, If there is no other device to fix it, the upper leg is not only flowable when transporting and storing on the gasket, but also the inconvenience of using the noise is generated. There was a defect that could not be kept fixed, and the rotation fixing piece was fixed on the bottom of the top plate. Due to the complicated structure such as the support for reinforcing bar or the bridge connected to the upper leg, and the pivoting piece, the weight of gyoza is increased, and the coarse structure increases the unit cost due to the difficulty of manufacturing process and the consumption of many materials. There was a waste-disposal stage such as an increase in productivity and a decrease in productivity.

따라서, 본 고안은 상기와 같은 제반 문제점과 폐단을 일소하기 위하여 안출한 것으로, 본 고안의 목적은 상의 상면판 하부에 통상적으로, 설치되는 측판의 내측면에 괘지편과 함께 상다리를 축착하고, 상다리의 회전축봉 직하부 관통공에 괘지봉을 탄설한 고정장치를 삽설한 구조에 의하여 상다리의 펼침과 접힘상태시 괘지봉이 괘지편으로 출몰입작동하면서 괘, 해지되므로서, 상다리를 간편용이하게 견고히 고정시킬 수 있도록 한데 있는 것이며, 또다른 목적은 단지 하나의 괘지편과 함께 상다리에 괘지봉의 고정장치를 삽설한 간단한 구조로서, 종래 교자상의 상다리 고정장치를 위한 부수적인 복잡한 구조를 거의 배제하므로서, 교자상의 제작공정의 간편성은 물론, 교자상의 중량을 대폭 감소시켜 운반과 그 사용을 보다 편리하게 한데 있는 것이다.Therefore, the present invention has been devised to eliminate all the problems and closing ends as described above, the object of the present invention is usually in the lower part of the upper surface of the upper plate, and the upper and lower limbs on the inner side of the side plate to be installed, the upper and lower legs The fixed rod is fixed to the upper and lower part of the rotary shaft by inserting a fastening device with a fixed rod in the hole. The other object is a simple structure in which a fastening device of the fastening rod is inserted into the upper leg together with only one fastening piece, and almost eliminates the additional complicated structure for the upper leg fixing device in the conventional gyoza. In addition to the simplicity of the manufacturing process, the weight of gyoza is greatly reduced, making transportation and use more convenient. All.

즉, 교자상(100)의 상면판(1) 하부의 사각테두리에 통상적으로 설치되는 측판(2)과 이의 네모서리부 내측면에 각각 상다리(20)를 절첩 가능하게 축착시킨 상다리의 고정장치를 구성함에 있어서, 제1도 및 제2도와 같이, 상기 측판(2)의 내측면에 축공(3)과 괘지공(4) 및 반구상의 괘지요홈(5)이 형성된 괘지편(10)이 밀착게재되어 상다리(20)의 상단부 축공(21)과 괘지편(10)의 축공(3)이 일치된 상태에서, 고정와샤(31)와 양단에 나사부(32)가 형성된 회전축봉(30)이 축삽되어서, 와샤(33) 및 너트캡(34)으로 상다리(20)가 측판(2)의 괘지편(10)에 축착지지되어 있다.That is, the upper plate (1) of the lower side plate (1) of the side plate (2) that is usually installed on the inner edge of the upper edge (20) and the upper leg (20) to fold the upper leg 20 is fixed to the fixing device of the upper leg In Figure 1, as shown in Figures 1 and 2, the hanging piece 10 is formed in close contact with the shaft hole (3) and the hanging hole (4) and the hemispherical hanging groove (5) on the inner surface of the side plate (2) In the state where the upper end shaft hole 21 of the upper leg 20 and the shaft hole 3 of the hanging piece 10 coincide with each other, the fixed shaft 31 and the rotary shaft bar 30 having the screw portions 32 formed at both ends thereof are inserted into the shaft. The upper leg 20 is fixedly supported on the hanging piece 10 of the side plate 2 by the washer 33 and the nut cap 34.

또한, 본 고안의 핵심 기술구성이라 할 수 있는 고정장치의 구성에 있어서는 상기 상다리(20)의 회전축봉(30) 직하부 편향된 위치에 관통공(21)이 형성되어 있고, 이 관통공(21)에는 일측단에 통공(22)이 형성되고 타측단이 개방된 파이프(23)가 삽치 고정되어 있으며,파이프(23)의 내측에는 로드(24)를 갖는 괘지봉(25)이 스프링(26)과 함께 탄삽되어, 상기 괘지편(10)의 괘지공(4)과 괘지요홈(5)에 대향하여 탄발적으로 출몰입 작동하면서, 상다리(20)를 괘,해지시킬 수 있도록 되어 있다.In addition, in the configuration of the fixing device, which can be referred to as the core technical configuration of the present invention, a through hole 21 is formed at a position deflected directly below the rotary shaft bar 30 of the upper leg 20, and the through hole 21 is provided. There is a through-hole 22 is formed at one end and the pipe 23 is open and the other end is fixedly fixed, the inner side of the pipe 23 has a rod 25 having a rod 24 is a spring 26 and It is inserted together, it is possible to swing and release the upper leg (20) while moving in and out sporadically opposing the hanging hole 4 and the hanging groove 5 of the hanging piece (10).

또한, 괘지봉(25)의 로드(24) 끝단에 형성된 나사부(27)는 파이프(23)의 일측단 통공(22)으로 관통되어 노브(28)가 나삽고정되어서 구성된 것이다.In addition, the screw portion 27 formed at the end of the rod 24 of the hanging bar 25 is configured to penetrate through the through-hole 22 of one end of the pipe 23 so that the knob 28 is screwed in.

이상과 같이, 구성된 본 고안의 작용효과를 설명한다.As described above, the effect of the present invention configured.

본 고안의 상다리 고정장치는 교자상(100)이 상면판 하부에 설치된 측판(2)의 모서리 내측에 각각 동일구조로 설치되어 있는 바, 상다리(20)의 절첩에 따른 수직상의 펼침상태와 수평상의 접힘상태에서, 상다리(20)를 고정시키기 위한 작동 실시예를 구체적으로 부연하여 보면, 먼저, 상다리(20)에 설치된 고정장치의 괘지봉(25)은 제2도(a)와 같이, 파이프(23)내에 탄설된 스프링(26)에 의하여 항시 측판(2)의 괘지편(10) 방향ㅇ로 탄발력을 갖게 된다.The upper leg fixing device of the present invention is installed in the same structure inside the corners of the side plate (2) is installed on the lower part of the upper plate, the vertical unfolded state and the horizontal folding according to the folding of the upper leg (20) In the state, in detail the working embodiment for fixing the upper leg 20, first, the ruled rod 25 of the fixing device installed on the upper leg 20, as shown in FIG. The spring 26 that is installed in the c) always has a spring force in the direction of the hanging piece 10 of the side plate 2.

따라서, 상다리(20)를 펼침상태로 고정시킬 경우에는 수평상태로 접혀 있는 상다리(20)를 제3도(a)와 같이, 수직으로 회동시켜 펼치게 되면 상다리(20)의 관통공(21)에 탄설된 괘지봉(25)이 괘지편(10)의 내측면을 타고 미끄러지듯 시계반대 방향으로 회동하다가 괘지공(4) 속으로 탄삽되므로서, 제2도 (a)와 같이, 상다리(20)가 수직으로 견고하게 고정되는 것이며, 다시 상다리(20)를 접을 경우에는 제2도 (a)와 같이, 괘지편(10)의 괘지공(4)에 탄삽되었던 괘지봉(25)을 해지시켜야 하는 바, 제2도 (b)와 같이, 괘지봉(25)의 로드(24)에 나착된 노브(28)를 잡아당긴 후, 상다리(20)를 수평상태로 눕히게 되면, 괘지봉(25)이 파이프(23)내로 몰입되므로서 상다리(20)는 괘지편(10)으로부터 회동절첩 가능하게 해지된다.Therefore, when the upper leg 20 is fixed in the open state, the upper leg 20 which is folded in the horizontal state is rotated vertically as shown in FIG. 3 (a), and when the upper leg 20 is unfolded, it extends to the through-hole 21 of the upper leg 20. As the slided barley 25 is rotated counterclockwise as if sliding on the inner surface of the walled paper 10, it is inserted into the walled ball 4, and as shown in FIG. 2 (a), the upper leg 20 Is firmly fixed vertically, and when the upper leg 20 is folded again, as shown in FIG. 2 (a), the ruled bar 25, which has been inserted into the ruled hole 4 of the ruled piece 10, must be released. Bar, as shown in FIG. 2 (b), after pulling the knob 28 attached to the rod 24 of the hanging bar 25, and then placing the upper leg 20 in a horizontal state, the hanging bar 25 By being immersed in the pipe 23, the upper leg 20 is released from the hanging piece 10 so that it can be rotated.

이때, 상다리(20)의 괘지봉(25)은 괘지편(10)의 괘지공(4)으로부터 빠져나온 후, 상술한 바와 같이 괘지편(10)의 내측면을 타고 미끄러지듯 시계방향으로 회동하다가 괘지요홈(5)으로 탄삽되어 상다리(20)가 제3도(b)와 같이, 접혀진 수평상태로 견고하게 고정되는 것이다.At this time, the ruled rod 25 of the upper leg 20, after exiting from the ruled ball 4 of the ruled piece 10, rotates clockwise as if sliding on the inner surface of the ruled piece 10 as described above. The upper leg 20 is inserted into the recess 5 and the upper leg 20 is firmly fixed in a folded horizontal state as shown in FIG.

이와같은, 상태에서 다시 상다리(20)를 수직상의 펼침상태로 회동시킬시 회동가압력에 의해 괘지봉(25)은 반구상으로요입된 괘지요홈(5)으로부터 미끄러지듯 빠져나오면서 파이프(23)의 내측으로 탄압몰입되므로서 괘지봉(25)의 노브(28)를 잡아당길 필요가 없는 것이며, 다만, 상다리(20)를 접을 경우에만 괘지봉(25)의 노브(28)를 잡아당기는 수고가 필요하게 되는 것이다.In such a state, when the upper leg 20 is rotated to the vertically expanded state again, the hanging bar 25 is slipped out of the hanging groove 5 recessed into the hemispherical shape by the rotational pressing force of the pipe 23. It is not necessary to pull the knob 28 of the hanging bar 25 while being crushed inward, but it is necessary to pull the knob 28 of the hanging bar 25 only when the upper leg 20 is folded. Will be done.

이상과 같이, 본 고안은 종래 교자상의 상다리 고정장치의 복잡한 구조에 비하여 소요자체가 적게들고 전체 구조가 매우 간단하여 제작의 간편성은 물론, 그에 따른 생산성 증대 및 제품불량의 감소와 제작단가를 절감할 수 있는 것이며, 특히, 본 고안은 상다리(20)에 설치된 괘지봉(5)의 노브(28)를 단한번 잡아당기는 간단한 작동조작으로, 상다리(20)의 절첩에 따른 펼침과 접음상태의 고정을 매우 간편용이하게 하여 교자상의 사용을 보다 편리하게 한 실용적인 유용한 고안인 것이다.As described above, the present invention is less complicated than the complicated structure of the upper leg fixing device on the conventional gyoza and the overall structure is very simple, so as to simplify the production, thereby increasing productivity, reducing product defects and reducing manufacturing costs. In particular, the present invention is a simple operation to pull the knob 28 of the hanging bar (5) installed in the upper leg (20) once, and secures the expansion and folding of the upper leg (20) by folding.
