Description
제1도는 본 고안의 일부를 분해한 사시도.1 is an exploded perspective view of a part of the present invention.
제2도는 본 고안의 조립상태 단면도.2 is a cross-sectional view of the assembled state of the present invention.
* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings
1 : 손잡이관 2 : 심봉1: handle tube 2: mandrel
3 : 중량체 4,4' : 환상홈3: weight 4,4 ': annular groove
6 : 중심체결턱 7,7' : 스냅링6: center tie chin 7,7 ': snap ring
본 고안은 아령의 중량체와 손잡이를 각각 별도로 형성하고, 손잡이의 양단부에 착설되는 중량체가 회동가능하게 착설됨과 동시에, 중량체와 손잡이를 극히 용이하게 분해조립될 수 있도록 구성하므로서 기계적가공에 의한 대량생산에 적합한 아령을 제공하기 위한 것이다.The present invention is to form a weight and a handle of the dumbbell separately, and the weight to be installed on both ends of the handle is installed so as to rotate, and the mass and the handle is configured so that it can be easily assembled and disassembled in large quantities by mechanical processing To provide a dumbbell suitable for production.
종래에도 아령의 중량체와 손잡이를 각각 별도로 형성하여 조립시킨 것이 알려져 있으나(실용신안출원공고 제85-3322호 참조), 이는 양측 중량체 사이를 연결봉으로 연결시킨 후 연결봉의 양단을 너트로 조여 체결하게 된 것이어서, 분해조립공정이 복잡하고, 나사조임으로 인한 중량체와 손잡이의 긴착으로 인하여 중량체가 회동될 수 없는 것이었고, 또한 중량체가 회동하는 경우에는 나사가 이완되므로서 운동중에 중량체가 낙하하게 되는 등의 위험성을 갖는 것이었다.Conventionally, it is known that the weight and handle of the dumbbell are separately formed and assembled (see Utility Model Application No. 85-3322), but this is connected by connecting rods between both weights with a connecting rod, and then tightening both ends of the connecting rod with nuts. Since the disassembly and assembly process is complicated, the weight cannot be rotated due to the tight attachment of the weight and the handle due to the screw tightening, and in the case of the rotation of the weight, the weight is dropped while the screw is relaxed. There was a risk of being.
본 고안은 이와같은 종래의 문제점을 해결하기 위하여 분해조립이 극히 간단하면서도 손잡이와 중량체가 안전하게 체결되며, 중량체가 회동될 수 있도록 구성한 것으로서 이하도면에 따라 상세히 설명하면 다음과 같다.The present invention is configured to allow the handle and the weight to be securely fastened, and the weight can be rotated in an extremely simple disassembly and assembly in order to solve the conventional problems as described below in detail according to the drawings.
합성수지제의 손잡이관(1)내에 삽입된 심봉(2)의 양단부에 중량체(3)를 착설하게 된 것에 있어서, 심봉(2)의 양단부에 각각 일정폭으로 2개의 환상홈(4)(4')을 굴설하고, 중량체(3)의 중심공(5)내로 심봉(2)의 양단부를 삽입하여 중량체(3)의 중심체결턱(6)이 2개의 환상홈(4)(4') 사이에 위치하도록 환상홈(4)(4')에 각각 스냅링(7)(7')을 체결하여서 된 것이다. 도면중 부호 8은 중량체(3)의 중심공(5)에 끼워지는 캡이며, 9는 중량체(3)의 외주면에 착설된 탄성링이다.In the installation of the weight body 3 at both ends of the mandrel 2 inserted in the handle tube 1 made of synthetic resin, two annular grooves 4 and 4 each having a predetermined width at both ends of the mandrel 2. ') Is excavated, and both ends of the core rod 2 are inserted into the center hole 5 of the weight body 3 so that the center fastening jaw 6 of the weight body 3 has two annular grooves 4 and 4'. The snap rings 7 and 7 'are respectively fastened to the annular grooves 4 and 4' so as to be positioned between them. In the figure, reference numeral 8 is a cap fitted to the center hole 5 of the weight body 3, and 9 is an elastic ring mounted on the outer circumferential surface of the weight body 3.
이와같이 구성된 본 고안은 심봉(2)에 삽착된 중량체(3)의 양측면이 스냅링(7)(7')에 의하여 협지된 상태가 되므로서 중량체(3)는 심봉(2)을 중심으로 하여 회전할 수 있는 것이나, 심봉(2)의 축방향으로는 이동되지 못하는 것이고, 스냅링(7)(7')은 환상홈(4)(4')내에 깊숙히 삽입된 상태이므로 스냅링(7)(7')은 스라스트베어링과 같은 작용을 나타내어 심봉(2)이나 중량체(3)가 회동하더라도 스냅링(7)(7')은 항상 견고한 협지상태를 유지하게 되므로 안전하게 사용할수 있는 것이며, 아령을 분해조립함에 있어서는 스냅링(7)(7')을 착탈시키므로서 극히 간단하게 분해조립이 이루어지는 것이고, 각 부분은 단순한 기계적 가공에 의하여 성형되는 것이어서 제작이 용이하여 대량생산에 적합하며, 각기 중량이 다른 중량체(3)를 교체사용하기에는 편리한 작용효과를 나타내게 되는 것이다.The present invention configured as described above has a state in which both sides of the weight body 3 inserted into the mandrel 2 are sandwiched by snap rings 7 and 7 ', so that the weight body 3 is centered on the mandrel 2. It is rotatable, but not moved in the axial direction of the mandrel 2, the snap ring (7) (7 ') is inserted deeply into the annular groove (4) (4'), so the snap ring (7) (7) ') Has the same effect as thrust bearing, so even if the mandrel (2) or the weight (3) is rotated, the snap ring (7) (7') always maintains a firm clamping state so that it can be used safely. In assembling, disassembling and assembly are extremely simple by removing the snap rings (7) and (7 '), and each part is molded by simple mechanical processing, which is easy to manufacture, and is suitable for mass production. It is convenient to replace the sieve (3). It will be for me.
