본 고안은 앞, 뒷바퀴가 동시에 제동되는 브레이크장치에 있어서 좌우측 어느쪽의 손잡이 브레이크를 사용하더라도 자전차의 뒤바퀴부터 제동이 걸린 다음 앞바퀴가 제동되게 하여 자전차 제동시에 균형이 깨져서 탑승자가 넘어지는 등 위험을 제거하기 위한 자전차 앞, 뒷바퀴 동시 브레이크장치의 개량에 관한 것이다.The invention devises a risk that the front wheel is braked from the rear wheel of the bicycle and the front wheel is braked even when the front and rear wheels are braked at the same time so that the front wheel is braked. A retrofit of the front and rear wheel brakes for removal of the bicycle.

종래에는 자전차 손잡이 브레이크와 앞, 뒷바퀴 브레이크가 따로따로 자전차에 장치되어 있기 때문에 파열로 인하여 충돌과 추돌사고를 유발하는 경우가 종종 있었으므로 이를 시정하기 위하여 자동봉 상하에 브레이크선을 동시에 걸착하여 앞, 뒷바퀴가 동시에 제동되게 하므로서 브레이크의 어느하나가 파손되더라도 제동이 걸리게 한 것이 있었으나, 이 경우는 앞, 뒷바퀴가 동시에 재동되므로서 탑승자의 균형이 깨져 넘어질 위험을 면치 못하였다.In the related art, since the brake handle brake and the front and rear wheel brakes are separately installed in the bicycle, collisions and collisions have often been caused by the rupture. As the rear wheels were braked at the same time, the brakes were applied even if any of the brakes were broken, but in this case, the front and rear wheels were restarted at the same time.

본 고안은 이와같은 문제점을 해결하기 위하여 브레이크를 편심캡에 동시 결착하여 뒷바퀴 브레이크선 결착공을 앞바퀴 브레이크선 결착공 보다 피치원상의 거리를 멀게 하므로서 브레이크 작동시 뒷바퀴에 제동이 먼저 걸리게 하여 탑승자의 균형을 유지하게 한 것으로서, 본 고안을 첨부도면에 의거 상세히 설명하면 다음과 같다.In order to solve this problem, the present invention simultaneously fixes the brake to the eccentric cap to make the rear wheel brake line binding hole farther from the pitch circle than the front wheel brake line binding, so that the brake is applied to the rear wheel first when the brake is operated. As to maintain, when described in detail based on the present invention the accompanying drawings as follows.

와이어 안내공(3)(3')(4)(4')이 상하로 천설된 갑체(1) 내벽 일측에 너트공(2')이 형성된 축봉(2)을 내향돌설하고 축공(6)과 와이어 결착공(7)(7')(7")(7'")이 친설된 편심캠(5)을 상기 축봉(2)에 감삽유설하여 코일스프링(8)으로 탄지하고 와이어 결착공(7)에는 왼손브레이크선(11)을, 와이어 결착공(7')에는 오른손 브레이크선(11')을, 축공(6) 중심에서 가까운 피치원상의 와이어 결착공(7")에는 앞바퀴 브레이크선(12)을, 축공(6) 중심에서 먼 피치원상의 와이어 결착공(7'")에는 뒷바퀴브레이크선(12')을 각각 결착하고, 뚜껑(9)을 씌운 후 볼트(10)로 체결하여 된 것이다.Wire guide holes 3, 3 ', 4, and 4' protrude inwardly through shafts 2 formed with nut holes 2 'on one side of the inner wall of the upper body 1, which are laid up and down. The eccentric cam 5, in which the wire binding holes 7, 7 ′, 7 ″, 7 ′ ”are familiar, is inserted into the shaft bar 2 and supported by a coil spring 8 to hold the wire binding hole 7. ), The left hand brake line 11, the wire binding hole 7 ', the right hand brake line 11', and the wire binding hole 7 "near the center of the shaft hole 6, the front wheel brake line 12 ), The rear wheel brake wire 12 'is respectively attached to the wire binding hole 7' "in the pitch circle far from the center of the shaft hole 6, and it is fastened with the bolt 10 after covering the lid 9. .

본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention is as follows.

장설된 왼손브레이크선(11)과 오른손브레이크선(11')이 편심캡(5)의 축공(6) 중심에서 동일거리에 형성된 결착공(7)(7')에 결착되어 있으므로 좌우 레버가 각 와이어의 부착위치에 관계없이 항상 일정하게 작동되며 어느한쪽에 고장이 나더라도 브레이크가 작동되므로 안전하고 뒷바퀴브레이크선(12')은 편심캠(5)의 축공(6) 중심에서 거리가 먼 피치원상에 위치하는 와이어 결착공(7"")에, 앞바퀴 브레이크선(12)을 편심캠(5)의 축공(6) 중심에서 거리가 가까운 피치원상에 위치하는 결착공(7")에 결착함으로 뒷바퀴부터 제동이 걸린 앞바퀴가 제동되므로 급브레이크로 인하여 탑승자가 균형을 잃고 넘어가는 것을 방지할 수 있고, 브레이크 제동으로 인한 충격이 뒷바퀴부터 가해지므로서 차체에 무리가 가지 않으며, 뒷바퀴브레이크선(12')과 앞바퀴브레이크선(12)이 편심캡(5)에 결착되어 있으므로 일측 브레이크가 파손되었더라도 다른 일측이 제동되므로 브레이크 파열로 인한 사고를 방지할 수 있는 매우 유용한 고안이다.Since the installed left hand brake line 11 and the right hand brake line 11 'are bound to the binding holes 7 and 7' formed at the same distance from the center of the shaft hole 6 of the eccentric cap 5, the left and right levers Regardless of the attachment position of the wire, it is always operated constantly and the brake is operated even if one side breaks down, so it is safe and the rear wheel brake line 12 'is pitch-distant from the center of the shaft hole 6 of the eccentric cam 5. The rear wheel brake line 12 by binding the front wheel brake wire 12 to the binding hole 7 "located on the pitch circle close to the center of the axial hole 6 of the eccentric cam 5; Since the front wheel braked from the brake is braked, it is possible to prevent the occupant from losing balance due to the rapid brake, and the impact of the brake braking is applied from the rear wheel, so that the body is not overwhelmed and the rear wheel brake line (12 ') And front brake brakes (12 ) Is attached to the eccentric cap (5), so even if one side of the brake is broken, the other side is braking is a very useful design that can prevent accidents due to brake rupture.
