Description

Chair leg of metal goods}

본 고안은 금속제 의자지지다리에 관한 것으로, 더욱 구체적으로 설명하면, 상부에 의자가 배치되며 하부에 캐스터가 부착되는 5개의 수평으로 분기된 다리본체가 형성된 금속제 의자지지다리를 용접부위가 현저하게 줄어들어 제조가 용이한 금속제 의자지지다리에 관한 것이다.The present invention relates to a metal chair support leg. More specifically, the welding part is significantly reduced in a metal chair support leg having five horizontally branched leg bodies having a chair disposed thereon and a caster attached to the bottom thereof. It relates to a metal chair support leg that is easy to manufacture.

일반적으로, 사무용 의자는 하단에 캐스터가 부착된 5개의 분기된 다리본체를 갖는 의자지지다리가 널리 이용되고 있다. 이러한 의자지지다리는 주로 합성수지로 제조되나, 고가의 제품에는 금속판으로 형성된 금속제 의자지지다리가 사용되고 있다. 이러한 종래의 금속제 의자지지다리는, 도 6에 도시된 바와같이, 중앙에 중심봉이 삽입고정되는 원통형고정관(100)이 형성되고 상기 원통형중심관(100)의 외측에는 하단에 캐스터가 고정되는 5개의 다리본체(200)가 원통형고정관(100)의 외측면에 용접고정된다. 이러한 다리본체(200)의 용접은 원통형고정관(100)에 접하는 다리의 2곳의 양측면(200a)을 각기 용접하여야 하므로 5개의 다리본체(200)를 용접하기위해서는 10곳의 부위를 용접하여야 하므로 용접시간이 오래걸리며 다수의 인력을 사용하여야 하는 문제점이 있었다. 또한 종래의 다리본체(200)에는 캐스터를 고정하기위해 다리의 선단부에 캐스터고정부를 형성하기위하여 캐스터고정부를 용접부착하였으나, 이러한 캐스터고정부의 용접은 상당히 세심한 주의를 가지고 용접을 하여야하므로 용접작업이 더디고 불량율이 많다는 문제점이 있었다.In general, office chairs are widely used chair support legs having five branched leg body attached to the caster at the bottom. Such chair support legs are mainly made of synthetic resin, but metal chair support legs formed of metal plates are used for expensive products. As shown in FIG. 6, the conventional metal chair support leg is formed with a cylindrical fixing tube 100 into which a central rod is fixed at the center thereof, and five casters are fixed to the lower end of the cylindrical center tube 100. The leg main body 200 is fixed to the outer surface of the cylindrical fixing tube 100 by welding. Since the welding of the leg body 200 has to weld two side surfaces 200a of the two legs in contact with the cylindrical fixing tube 100, respectively, in order to weld the five leg body 200, the welding of 10 sites is necessary. It takes a long time and had a problem of using a large number of manpower. In addition, in the conventional leg body 200, the caster fixing part is attached to the caster fixing part to form the caster fixing part at the tip of the leg to fix the caster. However, the welding of the caster fixing part should be carried out with great care, so the welding is performed. The problem was that the work was slow and the defective rate was many.

본 고안의 목적은, 이러한 문제점을 해결하기위한 것으로, 용접작업부위를 현저하게 감소시켜 제조시간이 현저하게 단축되고 작업인력이 감축되어 저렴하게 제조하는 것이 가능한 금속제 의자지지다리를 제공하는 것이다.An object of the present invention is to solve such a problem, and to provide a metal chair support leg that can significantly reduce the welding work site, significantly shorten the manufacturing time, reduce the work force, and manufacture at low cost.

본 고안의 다른 목적은 다리본체의 선단부에 고정되는 캐스터고정부를 용이하게 형성가능하게되어 그 제조가 용이하고 제조가가 저렴한 금속제 의자지지다리를 제공하는 것이다.Another object of the present invention is to be able to easily form a caster fixing portion fixed to the front end of the leg main body to provide a metal chair support leg is easy to manufacture and low cost.

본 고안의 이러한 목적들은 중앙에 중심봉삽입공이 형성되고 상하반분되되게 형성되는 상하 중심봉고정부와, 상기 상하 중심봉고정부의 측면에 일단부가 용접되고 타단부에는 캐스터고정부가 끼워맞춤 조립되는 5개의 다리본체로 구성되고, 상기 인접한 다리본체와 상하 중심봉고정부는 동시에 용접고정되는 본 고안에 따른 금속제 의자지지다리에 의하여 달성된다.These objectives of the present invention are the upper and lower center rod fixing portion which is formed in the center and the center rod insertion hole is formed in the upper and lower half, and the five ends of one end welded to the side of the upper and lower center rod fixing portion, and the caster fixing portion is fitted to the other end Consisting of the main body, the adjacent leg body and the upper and lower center rod fixing parts are achieved by the metal chair support legs according to the present invention, which are welded and fixed at the same time.

본 고안의 일실시예에 따른 금속제 의자지지다리(A)는, 도면에 도시된 바와같이, 중앙에 중심봉삽입공(10)이 형성되고 상하 반분되되게 형성되는 상하 중심봉고정부(1,1)와, 상기 상하 중심봉고정부(1,1')의 측면에 일단부가 용접되고 타단부에는 캐스터고정부(2)가 끼워맞춤 조립되는 5개의 다리본체(3)로 구성된다.Metal chair support leg (A) according to an embodiment of the present invention, as shown in the figure, the center rod insertion hole (1, 1) is formed so that the center rod insertion hole 10 is formed in the center and divided up and down half And, one end portion is welded to the side of the upper and lower center rod fixing portion (1, 1 ') and the other end is composed of five leg body (3) is fitted with the caster fixing portion (2).

상기 상부의 중심봉고정부(1)의 외측은 하향으로 절곡된 외측절곡면(11)과 중심봉삽입공(10)에서 내측하향으로 절곡된 내측하향절곡면(12)이 형성되고, 하부의 중심봉고정부(1')의 외측의 상향으로 절곡된 외측절곡면(11')과 중심봉삽입공(10)에서 하향으로 절곡된 내측하향절곡면(12')이 형성되어 있다.The outer side of the upper center rod fixing part 1 is formed with an inner downward bending surface 12 bent downward inward from the outer bent surface 11 and the central rod insertion hole 10 bent downward, The outer bent surface 11 'which is bent upward of the outside of the government part 1' and the inner downward bent surface 12 'which are bent downward in the central rod insertion hole 10 are formed.

상기 각 다리본체(3)는 금속판재로형태로 절곡형성되어 있다. 상기 다리본체(3)의 선단에는 상기 캐스터고정부(2)가 고정되는 절곡고정부(31)가 형성되어 있다.Each leg body (3) is made of a metal plate It is bent in shape. At the tip of the leg body 3, a bending fixing part 31 to which the caster fixing part 2 is fixed is formed.

상기 캐스터고정부(2)의 저면에는 상기 다리본체(3)의 절곡고정부(31)에 끼워맞춤조립되는 조립걸림턱(21)이 형성되고 상기 조립걸림턱(21)의 상방에는 조립걸림턱이 탄성적으로 작동되도록 탄성홈(23)이 형성되고 중간에는 캐스터고정공(22)이 형성되어 있다.An assembly catching jaw 21 is formed on the bottom of the caster fixing portion 2 to fit and assemble the bending fixing portion 31 of the leg body 3, and an assembly catching jaw above the assembly catching jaw 21. An elastic groove 23 is formed to operate elastically, and the caster fixing hole 22 is formed in the middle thereof.

본 고안의 특징은 용접작업을 최소로 하는 구조이다.The feature of the present invention is a structure that minimizes welding work.

상하 중심봉고정부(1,1')와 다리본체(3)를 배치하고 인접한 다리본체(3)와 함께 동시에 종방향으로 용접을 수행하면 2개의 다리본체의 일면(3a)과 중심봉고정부(1,1')가 1회의 용접으로 동시에 용접이 수행되므로 대단히 간단하게 용접을 수행할 수 있게되는 것이다. 이와같이 용접작업을 수행하면 5회의 용접작업으로 5개의 다리본체(3)를 용접고정시키는 것이 가능하게 되어 용접작업이 대폭적으로 줄어들게되는 것이다. 또한, 캐스터고정부(2)의 고정시, 캐스터고정부(2)의 조립걸림턱(21)을 다리본체(3)의 절곡고정부(31)로 밀어넣으면, 조립걸림턱(21)이 상부에 형성된 탄성홈(23)방향으로 휘어지면서 조립걸림턱(21)이 절곡고정부(31)를 통과하게되면 조립걸림턱(21)이 다시 원위치로 복귀되면서 절곡고정부(31)에 걸리게 되므로서 캐스터고정부(2)의 다리본체(3)에의 고정작업이 간단하게 종료되게 되는 것이다.When the upper and lower center bongo fixing parts (1, 1 ') and the leg body (3) are arranged and welding is performed in the longitudinal direction simultaneously with the adjacent leg body (3), one leg (3a) and the center bongo fixing part (1) of the two leg bodies are formed. Since 1 ') is simultaneously performed in one welding, welding can be performed very simply. When the welding operation is performed in this way, it is possible to fix the welding of the five leg bodies 3 by five welding operations, thereby greatly reducing the welding operation. In addition, when the caster fixing part 2 is fixed, when the assembly catching jaw 21 of the caster fixing part 2 is pushed into the bending fixing part 31 of the leg main body 3, the assembly catching jaw 21 is upper part. When the assembly catching jaw 21 passes through the bending fixing part 31 while being bent in the direction of the elastic groove 23 formed therein, the assembly catching jaw 21 returns to its original position and is caught by the bending fixing part 31. The fixing work of the caster fixing part 2 to the leg main body 3 is simply completed.

이상과 같이 본 고안에 따른 금속제 의자지지다리는 중심봉고정부에 다리본체의 용접에 대하여 용접회수가 종래에 비하여 2분의 1이하로 절감되므로서 제조비용이 저렴하게 되고 제조인력이 절감되고 제조시간이 단축되며 생산성이 향상되고, 다리본체의 선단에 캐스터고정부를 간단히 끼워맞춤방식으로 고정하는 것이 가능하게되어 작업공정이 단축되어 제조가가 저렴하게되는 우수한 효과가 있다.As described above, the metal chair support leg according to the present invention is reduced to less than one-half of the welding time for the welding of the leg body to the central bongoum, so that the manufacturing cost is low, the manpower is reduced, and the manufacturing time is reduced. This shortening and productivity is improved, and it is possible to simply fix the caster fixing portion to the tip of the leg body in a fitting manner, thereby reducing the work process and making the manufacturing cost cheaper.
