Description
본 고안은 덤벨의 축봉에 관한 것으로서 특히, 덤벨의 중량체를 고정하는 통상의 고정수단에 겉돌음방지 및 이탈방지의 수단을 부가한 것이다.The present invention relates to a shaft of a dumbbell, and in particular, the addition of the means of preventing overhang and departure to the usual fixing means for fixing the weight of the dumbbell.
종래의 덤벨축봉은 중량체를 고정하기 위하여 고정쇠에 고정볼트를 설치하는 것과, 고정체에 조임캡을 결합시키는 수단을 취하고 있다. 전자의 경우 고정볼트를 조이는 일이 번거로울 뿐만 아니라 부분조임으로 인하여 중량체의 무게를 이기지 못하고 고정쇠가 정위치에서 미끌어지는 위험이 있으며, 후자의 경우는 조임캡을 조일 때 고정체가 따라서 회전하므로 겉돌게 되며 전체조임이 이루어지기는 하나 중량체의 무게에 따라서는 역시 중량체가 이탈하는 현상을 피하기 어렵다.Conventional dumbbell shaft rod has a means for attaching a fastening cap to the fixing body to install the fixing bolt to the clamping body to fix the weight. In the former case, it is not only troublesome to fasten the fixing bolt, but also there is a risk that the clamping body will slip in place due to the partial tightening. Although the entire tightening is performed, depending on the weight of the weight, it is difficult to avoid the phenomenon that the weight is separated.
본 고안은 고정체와 조임캡의 결합부위에 겉돌음 방지구조 및 미끄러짐 방지구조를 부가함으로써 중량체의 조임이 손쉽고 중량체가 운동중 이탈하지 않고 정위치에 고정될 수 있는 구조를 제공하고자 한다.The present invention is to provide a structure that is easy to tighten the weight body and the weight body can be fixed in place without deviating during the movement by adding the anti-turning structure and the slip prevention structure to the coupling portion of the fixing body and the tightening cap.

본 고안의 구조를 첨부한 도면에 의거 상세히 설명한다.The structure of the present invention will be described in detail with reference to the accompanying drawings.
본 고안은 고정체(1)가 결합되는 철봉(2)의 둘레에 다수의 가로요철부(3)와 키홈(4)을 형성하고 고정체(1)의 결합공(5) 내면에는 이와 부합하는 다수의 가로요철부(3')와 키편(6)을 형성한 구조이다. 고정체(1)의 삽입부(7)는 할절되어 있어 둘레에 힘이 가해지면 직경이 수축되도록 구성되어 있으며 삽입부(7)의 전반부는 나선이, 후반부는 후방을 향하여 완만한 경사각을 가지고 있다. 삽입부(7)에 결합되는 조임캡(8)의 내부 전반부에는 나선이, 후반부에는 직경이 감소하도록 수렴관의 구조를 취하고 있다. 또한, 철봉(2)의 둘레는 손으로 잡았을 때 냉기를 느끼지 않도록 합성수지로 피복성형되어 있다.The present invention forms a plurality of transverse concave-convex portions 3 and key grooves 4 around the iron bar 2 to which the fixing body 1 is coupled, and the inner surface of the coupling hole 5 of the fixing body 1 corresponds to this. It is a structure in which a plurality of horizontally uneven portions 3 'and a key piece 6 are formed. The insert 7 of the fixture 1 is cut off so that the diameter is contracted when a force is applied to the circumference. The first half of the insert 7 has a helix and the second half has a gentle inclination angle toward the rear. . The inner half of the tightening cap 8 coupled to the insert 7 has a structure of a converging tube so that a spiral decreases and a diameter of the latter half decreases. In addition, the circumference | surroundings of the iron bar 2 are coat-molded with synthetic resin so that it may not feel cold when it is hold | handed by hand.
본 고안은 철봉(2)에 덤벨의 중량체를 고정턱(9) 까지 차례로 끼워 결합하고 고정체(1)를 끼워 밀착되게 한다. 철봉(2)의 키홈(4)에는 고정체(1) 결합공(5)의 내면에 형성된 키편(6)이 끼워지게 한다. 이때 철봉(2)의 가로요철부(3)와 고정체 (1) 결합공(5)의 내면에 형성된 가로요철부(3')도 서로 견고히 부합될 수 있는 상태가 된다. 고정체(1)의 삽입부(7)에 조임캡(8)을 끼워 나사조임하면 삽입부(7)가 조여지며 철봉(3)과 고정체(1)의 각 가로요철부(3)(3')는 서로 맞물려 견고히 결합된다.The present invention is coupled to the iron rod (2) by inserting the weight of the dumbbell up to the fixed jaw (9) in turn and to fit the fixed body (1). A key piece 6 formed on the inner surface of the fixing member 1 coupling hole 5 is fitted into the key groove 4 of the iron bar 2. At this time, the horizontal concave-convex portion (3) and the horizontal concave-convex portion (3 ') formed on the inner surface of the fixing body (1) coupling hole (5) is also in a state that can be firmly matched with each other. When screwing the fastening cap 8 into the insertion portion 7 of the fixing body 1, the inserting portion 7 is tightened, and each of the horizontal uneven portions 3 and 3 of the iron rod 3 and the fixing body 1 is tightened. ') Are tightly coupled to each other.
본 고안은 철봉과 고정체가 키홈 및 키편에 의하여 고정되므로 조임캡을 회전시켜 조일때 고정체가 겉도는 현상이 발생하지 아니하며 철봉과 고정체가 겉도는 현상이 발생하지 아니하며 철봉과 고정체가 가로요철부의 맞물림에 의하여 견고히 조여지므로 덤벨을 수직으로 기울이더라도 중량체의 무게에 의하여 고정체가 정위치에서 이탈되지 아니한다.The present invention is because the iron rod and the fixture is fixed by the key groove and the key piece, so that when the tightening cap is rotated, the fixture does not appear outwardly, the appearance of the iron rod and the fixture does not occur. Since it is firmly tightened by the engagement, even if the dumbbell is inclined vertically, the fixture will not be released from its position by the weight of the weight.
