Description
제1도는 본 고안의 조립 정면도.1 is an assembled front view of the present invention.
제2도는 본 고안의 작동 상태도.2 is a working state of the present invention.
제3도는 본 고안의 분해 사시도.3 is an exploded perspective view of the present invention.
본 고안은 아동용 자전거의 전륜 및 후륜의 허브축에 부착하는 외압박식 드럼형 ∨브레이크로서 종래의 밴드브레이크를 개량한 것이다.The present invention is an external pressure drum type shock brake that is attached to the hub shafts of the front and rear wheels of a children's bicycle and is an improvement of the conventional band brake.
지금까지 아동용 자전거에는 주로 밴드브레이크를 많이 사용하였는바, 그 이유는 밴드브레이크가 캘리퍼브레이크나 림브레이크에 비해 작동시킬 때 힘이 적게 들어 아동용으로 적합하기 때문이었다.To date, children's bicycles have often used band brakes because they are less powerful when operated than caliper brakes or rim brakes, making them suitable for children.
그런데 종래의 밴드브레이크는 자전거의 후륜에만 설치하고 허브의 길이가 짧은 전륜에는 설치할 수가 없는 결점이 있어 통상 전륜에는 브레이크 작동시 밴드브레이크보다 힘이 더 드는 캘리브레이크나 림브레이크를 많이 사용하여 왔다.However, the conventional band brake is installed only on the rear wheel of the bicycle and has a drawback that cannot be installed on the front wheel having a short hub length. Therefore, the front wheel has generally used cali brakes or rim brakes, which are more difficult than the band brakes when the brakes are operated.
이러한 결점을 해결하기 위하여 안출한 본 고안은 특히 지렛대를 이용한 작동간을 설치하여 적은 힘으로도 쉽게 브레이크를 작동시킬 수 있게 함으로써 운동신경이 충분히 발달하지 않은 아동들일 적은 힘으로도 브레이크 작동을 원활히 할 수 있도록 안출한 것으로 이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.The present invention devised to solve these shortcomings, in particular, installs an operation lever using a lever so that the brake can be easily operated with a small force, so that the children can not operate the brake smoothly with a small force. When described in detail based on the accompanying drawings as designed to be as follows.
즉, 상부에 장공(2), 중앙에 축공(3), 일측에 체결공(4)을 천공하고 하부 양쪽에 돌주(10(10')를 고정한 브레키트(1)에 장공(18)(18')을 천공한 두개의 작동간(5)(5')을 축(6)(6')으로 유설하여 장공(18)(18')에 돌주(10)(10')가 유삽되게 한 다음, 괘지공(19)(19')을 천공한 호형의 압박편(7)(7')의 상단을 체결축(8)으로 체결하여 그 돌출부를 상기 브래키트(1)의 장공(2)에 유삽하고, 하단은 작동간(5)(5')의 장공(18)(18') 상부에 위치하도록 각각 축(9)(9')으로 축설하며, 스프링(11)으로 돌주(10)(10')를 한번씩 권회하여 그 양단을 괘지공(19)(19')에 각각 괘지하여서 된 것으로, 미설명부호 12는 허브에 형성된 드럼, 13은 허브심봉, 14는 브레이크 와이어, 15는 와이어 케이블, 16은 자전거 골격의 일부이고, 17은 체결밴드이다.That is, the long hole (18) (18) to the hole (2) in the upper part, the shaft hole (3) in the center, the fastening hole (4) on one side and the brewer (1) fixed to the bottom 10 (10 ') on both sides '(5)' (5 ') is axially drilled on the shaft (6) (6') to allow the stone (10) (10 ') to be inserted into the long hole (18) (18'). , The upper end of the arc-shaped pressing piece (7) (7 ') which drilled the hanging hole (19) (19') is fastened with the fastening shaft (8), and the protrusion is inserted into the long hole (2) of the bracket (1). By inserting the lower ends of the shafts 9 and 9 ', respectively, so as to be located above the long holes 18 and 18' of the operating periods 5 and 5 ', 10 ') is rolled one by one, and both ends are hung on the hanging balls 19 and 19', respectively, in which reference numeral 12 is a drum formed in a hub, 13 is a hub mandrel, 14 is a brake wire, and 15 is a wire cable. 16 is part of the bicycle skeleton and 17 is the fastening band.
이와 같이 된 본 고안은 브레이크와이어(14)를 당기면 작동간(5)(5')이 상호 내향으로 작동하여 호형 압박편(7)(7')을 내향으로 작용케 함으로서 허브에 형성한 드럼(12)을 압박하여 회동을 제동하게 되고, 브레이크와이어(14)를 놓으면 스프링(11)의 탄발력이 작용하여 압박편(7)(7')이 원상 복귀하면서 허브의 드럼(12)을 해방시켜 줌과 동시에 작동간(5)(5')을 원상복귀시켜 주는 것으로 작동간(5)(5')의 지렛대 작용으로 압박편(7),(7')이 드럼(12)을 장악할 수 있도록 한 것을 특징으로 하여 아동들이 적은 힘으로도 브레이크 작동을 원활히 할 수 있게 된 것이다.The present invention as described above is a drum formed in the hub by actuating the arc-shaped pressing pieces (7) (7 ') inwardly by operating the inward (5) (5') mutually inward when the brake wire 14 is pulled ( 12) to brake the rotation, and release the brake wire 14, the spring force of the spring 11 acts to release the pressing piece (7) (7 ') to return to the original to release the drum 12 of the hub By pressing and returning between the operation (5) and (5 ') at the same time as the zoom, the pressing pieces (7) and (7') can grasp the drum (12) by the lever action of the operation (5) and (5 '). It is characterized in that children can smoothly operate the brakes with little force.
