본 고안은 리어카의 주행시 필요에 따라 바퀴를 편리하게 제동시킬 수 있도록 한 것으로 특히 리어카가 주행도중 펑크가 발생하더라도 리어카를 2중으로 제동시킬 수 있도록 한 리어카의 제동장치에 관한 것이다.The present invention allows for convenient braking of the wheels as needed during driving of the rear car, and more particularly relates to a braking device for the rear car which allows the rear car to be braked in double even when a puncture occurs during driving.
종래의 리어카에는 안전을 위한 제동장치가 불비하여 비탈길을 오를때에는 인력에 의하여 제동을 하거나 받침목등으로 제동하고 비탈길을 내려올때는 리어카 후면에 페라이어등을 착설하여 이를 지면과 마찰토록하므로서 바퀴를 원시적으로 제동하였던바, 이러한 종래의 리어카는 주행시 방향전환이 매우 힘들고 어려웠으며 비탈길에서 내려올때는 리어카의 하중과 가속이 작용되고 비탈길을 오를 때는 리어카의 하중에 의하여 인력으로는 리어카를 제동하기 어려워 운전자에게 많은 위험부담을 초래하였고 심한 경우 인사사고가 많이 발생하는 문제점이 있었다.The conventional rear car is equipped with a brake system for safety. When climbing up a slope, it is braked by manpower or braced by a support neck. The conventional rear car was very difficult and difficult to change direction when driving, and the load and acceleration of the rear car were applied when coming down the slope, and it was difficult to brake the rear car by the load by the rear car when climbing the slope. There was a problem that caused a lot of personnel accidents.
본 고안은 상기와 같은 종래의 제반문제점을 감안하여 리어카에 2중 제동장치를 설치하고 특히 펑크가 발생되더라도 제동이 될 수 있도록 안출한 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention, in consideration of the above-mentioned conventional problems, installed a double braking device in the rear car, and in particular, even when a puncture is generated to be braking to be described in detail by the accompanying drawings as follows.
리어카본체(1)의 양측 바퀴(2)중앙에 작동편(3)을 설치하고, 이의 상, 하에 연결봉(4)(41)을 설치하여 각 연결봉(4)(41)에는 제동구(51)와 스프링(6)이 탄설된 제동구(5)를 각각 연결 설치한다.An operating piece 3 is installed at the center of both wheels 2 of the rear carbon main body 1, and connecting rods 4 and 41 are installed at the upper and lower portions thereof, and each of the connecting rods 4 and 41 is provided with a braking hole 51. And the spring 6 is connected to the braking port 5 is installed.
그리고 축(8)에 설치되는 회동편(7)의 상, 하에는 링크(9)와 걸림편(11)을 가진 밀편(10)을 설치하고 밀편(10)의 일단은 제동구(5)에 설치된 스프링(6)에 탄설한다.In addition, upper and lower rotary pieces 7 installed on the shaft 8 are provided with a push piece 10 having a link 9 and a locking piece 11, and one end of the push piece 10 is provided at the braking hole 5. It installs in the installed spring (6).
리어카본체(1)의 전방에는 회동판(12)을 회전축(13)에 설치시키고 회동판(12)상부에는 링크(9)의 일단과 와이어(14)의 일단을 연결설치한다.A rotating plate 12 is provided on the rotating shaft 13 in front of the rear carbon body 1, and one end of the link 9 and one end of the wire 14 are connected to the rotating plate 12 above.
리어카의 손잡이(15)양측에는 핸들(16), (161)을 각각 설치하고 핸들(16)에는 고정편(17), 연결편(18), 레버(19)를 설치하여 레버(19)의 일단에 회동판(12)의 상부에는 일단이 연결된 외이어(14)의 타단을 연결 설치한다.Handles 16 and 161 are provided on both sides of the handle 15 of the rear car, respectively, and a fixing piece 17, a connecting piece 18, and a lever 19 are attached to the handle 16 at one end of the lever 19. The upper end of the rotating plate 12 is connected to the other end of the outer wire 14 is connected one end.
핸들(161)에는 폴리(20)와 기어(21) 및 스톱퍼(22)를 각각 설치하고 폴리(20)에는 와이어(141)를 권취하며 와이어(141)의 끝단은 리어카본체(1)의 저면에 설치된 회동구(23)에 연결한다.The handle 161 is provided with a poly 20, a gear 21, and a stopper 22, respectively, and a wire 141 is wound around the poly 20, and an end of the wire 141 is formed on the bottom surface of the rear carbon body 1. It is connected to the installed turning hole (23).
회동구(23)의 중앙에는 베어링(24)이 설치되며 회동구(23)의 양단에는 연결편(25)(251)이 각각 설치된다.A bearing 24 is installed at the center of the rotational opening 23, and connecting pieces 25 and 251 are respectively provided at both ends of the rotational opening 23.
각 연결편(25)(251)에는 제동구(52)(53)가 양단에 설치된 축(26)(261)이 연결설치되며, 상기 각 제동구(5)(51)(51)(53)는 바퀴(2)의 외주에 소정의 간격을 두고 설치되어 있다.Each connecting piece (25, 251) is provided with a shaft (26, 261) in which the braking holes (52, 53) are installed at both ends, each of the braking holes (5) (51) (51) (53) It is provided in the outer periphery of the wheel 2 at predetermined intervals.
이상과 같이 구성된 본 고안은 리어카의 주행도중 제4도와 같이 핸들(16)을 전방으로 밀어 (가) 위치에서 A위치로 이동시키면 연결편(18)에 연결된 레버(19)가 (b)위치에서 a위치로 이동되면서 와이어(14)를 당기게 되고 이에 따라 제2도와 같이 회동판(12)이 회전축(13)을 중심으로 회동되어 링크(9)를 당기므로 회동편(7)이 축(8)을 중심으로 회동되고 밀편(10)이 후방으로 밀린다.According to the present invention configured as described above, when the handle 16 is pushed forward as shown in FIG. 4 during the driving of the rear car, the lever 19 connected to the connecting piece 18 moves from the position (b) to the position a in the position (b). The wire 14 is pulled while moving to the position, and accordingly, as shown in FIG. 2, the pivoting plate 12 is rotated about the rotational shaft 13 to pull the link 9, so that the pivoting piece 7 pulls the shaft 8. It is rotated to the center and the push piece 10 is pushed backward.
밀편(10)이 후방으로 밀리면 스프링(6)에 압력이 가해져 제동구(5)가 바퀴(2)쪽으로 이동됨과 동시에 연결봉(4)이 이동되고 연결봉(4)에 설치된 작동편(3)이 회동하여 연결봉(41)을 당겨주므로 제동구(51)도 제동구(5)와 함께 바퀴쪽으로 이동되어 바퀴(2)를 제동하게 된다.When the push piece 10 is pushed backward, pressure is applied to the spring 6, the brake port 5 is moved toward the wheel 2, and at the same time, the connecting rod 4 is moved and the operating piece 3 installed on the connecting rod 4 is rotated. By pulling the connecting rod 41, the braking port 51 is also moved to the wheel with the braking port 5 to brake the wheel (2).
상기와 같은 과정에서 바퀴(2)에 펑크가 생기면 핸들(16)을 조금더 작동시키므로서 스프링(6)의 탄력과 압축력이 상기 보다 조금더 작용하여 펑크난 바퀴라 하더라도 제동할 수가 있다.If a puncture occurs on the wheel 2 in the above process, the elasticity and compressive force of the spring 6 act a little more than the above, while operating the handle 16 a little more.
또 제4도에서와 같이 핸들(16)을 B위치로 이동시켜 레버(16)를 조금 더 당기면 핸들(16)과 레버(19)가 일직선상으로 있게 되어 주차시등에는 주차용 제동장치로 이용할 수 있다.In addition, as shown in FIG. 4, when the handle 16 is moved to the B position and the lever 16 is pulled a little further, the handle 16 and the lever 19 are in a straight line. Can be.
상기와 같이 제동구(5) (51)를 이용하다가 이들의 연결부분등에 고장이 발생되면 핸들(161)을 이용하여 리어카본체(1)의 저면에 설치된 제2제동장치를 이용하게 되는데 이에 대한 작동상태를 보다상세히 하면, 제5 및 제6도에서와 같이 핸들(161)을 당기면 이에 설치된 기어(21)와 풀리(20)가 함께 와이어(141)를 당기게되고 와이어(141)가 당겨지면 회동구(23)가 회동하여 2개의 연결편(25) (251)이 동시에 내측으로 이동하여 축(26) (261)을 당겨주게 되므로 제동구(52) (53)가 바퀴(2)를 동시에 제동하게 되고 또한 바퀴에 펑크가 발생하는 경우는 상기의 회동구(23)가 더욱 회전되고 이에 따라 제동구(52) (53)의 동작거리가 많아지면서 제동이된다.As described above, when a failure occurs in the connection part of the brakes 5 and 51, a second braking device installed on the bottom surface of the rear carbon body 1 using the handle 161 is used. In more detail, as shown in FIGS. 5 and 6, when the handle 161 is pulled, the gear 21 and the pulley 20 installed thereon pull the wire 141 together, and when the wire 141 is pulled, the turning hole As the 23 rotates, the two connecting pieces 25 and 251 simultaneously move inward to pull the shafts 26 and 261 so that the brake holes 52 and 53 brake the wheel 2 at the same time. In addition, when the puncture is generated on the wheel, the above-described turning hole 23 is further rotated, and thus the operating distance of the braking holes 52 and 53 is increased and the braking is performed.
또 핸들(161)에는 기어(21)와 스톱퍼(22)가 설치되어 제동상태를 그대로 유지시킬수가 있고 스톱퍼(22)를 해제시킬시에는 제6도와 같이 스톱퍼(22)를 수동으로 재켜주면 된다.In addition, the handle 161 is provided with a gear 21 and a stopper 22 to maintain the braking state. When the stopper 22 is released, the stopper 22 may be manually turned on as shown in FIG.
이상과 같은 본 고안은 2개의 제동장치를 설치하므로서 비상제동이 가능하고 바퀴에 펑크가 발생되더라도 제동력이 우수하며 주차시에는 주차용 제동장치로도 이용할 수 있는 매우 실용적인 고안이다.The present invention as described above is an emergency braking is possible by installing two braking devices and excellent braking power even if a puncture occurs on the wheels, it is a very practical design that can be used as a parking braking device for parking.
