본 고안은 장농등과 같은 각종 가구를 수평상태로 높을수 있도록 하여주는 가구의 받침다리 승강조절 장치에 대한 것이다.The present invention relates to a lifting leg control device of the furniture that allows to raise the various furniture, such as long farm lamps in the horizontal state.

일반적으로 주택의 방바닥은 수평상태가 위치에 따라 다르기 때문에 가구를 수평 상태로 놓기 위해서 종래에는 가구의 밑에 나무조각 또는 종이등을 접어서 받쳐 주었다.In general, the floor of a house varies depending on the location, so in order to put the furniture in a horizontal state, a piece of wood or paper was folded and supported under the furniture.

그러나 이런 방법으로 가구의 수평상태를 맞추려면 가구의 무게에 의해 혼자서는 도저히 불가능 하였으며 또 가구를 여러번 들었다 놓았다 해야되므로 많은 시간과 인력은 물론 힘이들게 되어 통상 적당히 맞춰 놓은 경우가 허다 하였다.However, in order to level the furniture in this way, the weight of the furniture was almost impossible to do alone, and the furniture had to be lifted and placed several times.

따라서 장기간이 경과되면 가구의 수평상태가 맞지 않기 때문에 변형이 되어 문짝등이 잘 맞지 않게 되고 이에 따라 문짝은 물론 서랍등의 개폐가 잘되지 않게 되는등 문제점이 있었다.Therefore, after a long period of time, the furniture does not fit the horizontal state is deformed and the doors do not fit well, and accordingly there was a problem such as the door opening and closing of drawers, etc. is not good.

본 고안은 이와 같은 문제점들을 해결하기 위해 가구의 하부 네모서리부분에 각각의 한쌍의 베벨기어를 직각으로 치합되게 착설하여 같은 쪽의 앞뒤 상부 베벨기어를 전후진되게 착설하여 같은쪽의 앞뒤 상부 베벨기어를 전후진되게 착설하는 장축으로 연결시켜 이 장축을 회전시키면 상부 베벨기어의 회전으로 하부 베벨기어가 연동되어 이 베벨기어에 나사식으로 끼워져 있는 받침다리가 승강되도록 하므로 간편 용이하게 가구의 수평상태를 조절할수 있게 고안한 것이다.In order to solve these problems, the present invention installs a pair of bevel gears at right angles to the lower corners of the furniture at right angles, and installs the front and rear upper bevel gears forward and backward on the same side. Rotate this long shaft by connecting the lower bevel gear with the rotation of the upper bevel gear so that the supporting leg attached to this bevel gear can be lifted. It is designed to be adjustable.

이하 본 고안의 구성 및 작동상태를 첨부 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

가구(1)의 양쪽 하부 내면 전후 모서리 부분에 나선이 결합공(2a)의 내주면에 형성된 하부 베벨기어(2)(2')를 회전 가능하게 지지틀(3)(3')로 착설하고 이 베벨기어(2)(2')에는 상부에 절개홈(4)이 길게 형성되고 외면에 나선이 형성된 받침다리(5)(5')를 각각 나사식으로 끼워 결합하며 선단의 조정홈(6)만 가구(1)의 전면으로 노출되고, 받침다리(5)(5')의 절개홈(4)을 통과 하도록 착설하는 장축(7)의 전후에는 각각 상부 베벨기어(8)(8')를 끼워 고정시켜 앞쪽의 상부 베벨기어(8)가 스프링(9)으로 탄발되게 지지틀(3)(3')내에 착설하여 앞쪽의 상부 베벨기어(8)는 하부 베벨기어(2)와 치합되게 하고 뒤쪽의 상부 베벨기어(8')는 하부 베벨기어(2')와 일정간격으로 떨어져 있도록 하여서 된 것이다.The lower bevel gears (2) (2 ') formed on the inner circumferential surface of the coupling hole (2a) at both lower inner and front edges of both lower inner surfaces of the furniture (1) are rotatably installed in the support frame (3) (3'). Bevel gears (2) and (2 ') are formed by cutting grooves (4) formed in the upper portion and spirally formed support legs (5) (5') formed on the outer surface, respectively, by screwing, and adjusting grooves (6) at the ends. Only the upper bevel gears 8 and 8 'are exposed before and after the long shaft 7 which is exposed to the front of the furniture 1 and is installed so as to pass through the cutout grooves 4 of the supporting legs 5 and 5'. The upper upper bevel gear (8) is installed in the support frame (3) (3 ') so that the upper upper bevel gear (8) is elastic with the spring (9), and the upper upper bevel gear (8) is engaged with the lower bevel gear (2). The rear upper bevel gear 8 'is made to be spaced apart from the lower bevel gear 2' at regular intervals.

미설명 부호 "10"은 장축의 내단을 받쳐주는 받침부이다.Reference numeral 10 denotes a support portion that supports the inner end of the long axis.

이와 같이된 본고안은 제3도에서 보는바와 같이 장축(7)은 앞쪽에 고정착설된 상부 베벨기어(8)가 스프링(9)으로 탄발되게 착설되었기 때문에 평상시에는 장축(7)이 앞쪽으로 전진되어 있게 되므로 뒤쪽의 베벨기어(8')는 베벨기어(2')와 일전간격(P)만큼 떨어져 있게 되는 것으로 앞쪽 다리(5)높이를 조정할때에는 장축(7)이 전진되어 있는 상태에서 가구(1)의 전면으로 노출되어 있는 조정홈(6)에 공구를 끼워 장축(7)을 시계 방향으로 회전시켜 주면 베벨기어(8)(8')가 동시에 회전 되는데 이때 뒤쪽의 베벨기어(8')는 베벨기어(2')와 격리되어 있기 때문에 그 회전력은 앞쪽의 베벨기어(8)에서 베벨기어(2)로만 전달되어 이 베벨기어(2)를 회전시켜 준다.As shown in FIG. 3, the main axis 7 is generally moved forward because the upper bevel gear 8 fixedly mounted at the front is elastically installed with the spring 9, as shown in FIG. Since the rear bevel gear (8 ') is spaced apart from the bevel gear (2') by an interval (P), when the height of the front leg (5) is adjusted, the furniture (with the long shaft (7) advanced) Insert the tool into the adjustment groove 6 exposed to the front of 1) and rotate the long shaft 7 clockwise to rotate the bevel gears 8 and 8 'at the same time. Since is isolated from the bevel gear (2 '), the rotational force is transmitted from the front bevel gear (8) to the bevel gear (2) only to rotate the bevel gear (2).

이렇게 하여 베벨기어(2)가 회전되면 받침다리(5)는 그 상부에 형성된 절개홈(4)을 장축(7)이 통과하게 되어 있기 때문에 베벨기어(2)가 회전될때 함께 회전되지 않게 되므로 베벨기어(2)가 회전되면 결합공(2a)의 내주면에 형성된 나선과 받침다리(5)의 외주면에 형성된 나선의 작용에 의해 수직으로 하강하게 되며 반대로 장축(7)을 반시계 방향으로 회전시켜 주면 받침다리(5)는 수직으로 상승하게 되는 것이다.When the bevel gear 2 is rotated in this way, the support leg 5 is beveled because the long shaft 7 passes through the incision groove 4 formed in the upper portion thereof so that the bevel gear 2 is not rotated together. When the gear 2 is rotated, it is vertically lowered by the action of the helix formed on the inner circumferential surface of the coupling hole 2a and the helix formed on the outer circumferential surface of the support leg 5, and on the contrary, when the long axis 7 is rotated counterclockwise, Support leg 5 is to rise vertically.

한편 뒤쪽의 받침다리(5')의 높이를 조정할때에는 공구로 장축(7)을 밀어 주게되면 스프링(9)이 압축되면서 장축(7)이 뒤쪽으로 밀리게되어 앞쪽의 베벨기어(8)는 베벨기어(2)에서 떨어지고 대신 뒤쪽의 베벨기어(8')가 베벨기어(2')에 치합되므로 이때 장축(7)을 그대로 누른 상태에서 장축(7)을 필요한 방향으로 회전시켜 주면 그 회전력이 베벨기어(8')에 의해 베벨기어(2')로만 전달되어 받침다리(5')가 상술한 바와 같은 작용으로 승강 조정되는 것이다.On the other hand, when adjusting the height of the rear support leg 5 ', when pushing the long shaft 7 with a tool, the spring 9 is compressed and the long shaft 7 is pushed backward, so that the front bevel gear 8 is beveled. Bevel gear (8) falls behind the gear (2) and is instead engaged with the bevel gear (2 '). At this time, if the long shaft (7) is rotated in the required direction while pressing the long shaft (7), the rotational force is beveled. It is transmitted only to the bevel gear 2 'by the gear 8', and the supporting leg 5 'is lifted and adjusted by the above-described action.

이와 같이 작동되는 본 고안은 기구의 하부 전면으로 노출된 장축의 선단부만을 이용 장축을 전진된 상태에서 또는 후진시킨다음 회전시켜 앞뒤 받침다리의 높이를 임의로 승강자재시켜 주도록 하였기 때문에 필요에 따라 가구의 저면 네모서리에 착설된 각 받침다리의 높이를 각기 별개로 조정할수 있게 되어 혼자서도 간편 용이하게 가구를 수평상태로 되게 놓을수 있게되는 것이다.The present invention, which operates as described above, uses only the tip of the long shaft exposed to the lower front of the apparatus, so that the height of the front and rear support legs can be arbitrarily raised and lowered by rotating the long shaft in an advanced state or backward, and as necessary, the bottom of the furniture. The height of each support leg installed on the corner can be adjusted separately so that the furniture can be placed horizontally simply and easily.
