접이식 자전거{FOLDING BICYCLE}Folding bike {FOLDING BICYCLE}

본 발명은 접이식 자전거에 관한 것으로, 더욱 상세하게는 후륜 프레임을 전륜과 겹치도록 접을 수 있도록 하되, 메인프레임에 접이부를 형성하지 않음으로써 보다 강성이 강화될 수 있도록 한 접이식 자전거에 관한 것이다.The present invention relates to a folding bicycle, and more particularly, to a folding bicycle to be able to fold the rear wheel frame to overlap the front wheel, but to be more rigid by not forming a folding part on the main frame.

일반적으로 자전거는 프레임과, 안장 및 프레임의 전후방에 설치된 전륜 및 후륜 그리고 안장과 페달로 구성된다.In general, a bicycle consists of a frame, a saddle and front and rear wheels installed in front of and behind the frame, and a saddle and a pedal.

이러한 자전거는 다양한 형태와 구조로 진보되어 왔으며 최근에는 보관 및 운반이 용이하도록 부피를 보다 콤팩트하게 하기 위해 접을 수 있는 접이식 자전거가 시판되고 있다.These bicycles have been advanced in various forms and structures, and recently, folding bicycles are commercially available to make the volume more compact for easy storage and transportation.

현재 대중적으로 보급된 접이식 자전거는 프레임에 접이용 힌지를 형성함으로써 후륜부가 전륜부를 향해 수평으로 회전되어 절반으로 접히는 구조로 이루어진다.Folding bicycles, which are now widely available, have a structure in which the rear wheel portion is rotated horizontally toward the front wheel portion and folded in half by forming a folding hinge on the frame.

이러한 접이식 자전거는 주로 일상 생활에 사용되는 생활자전거에 적용되고 있으나 산악자전거와 같이 충격에 자주 노출되며 비교적 고가의 재질로 제작된 전 문자전거에는 적용되지 않고 있다. Such folding bicycles are mainly applied to everyday bicycles used in daily life, but are not exposed to shocks, such as mountain bikes, and are not applied to all bicycles made of relatively expensive materials.

또한 종래 접이식 자전거는 프레임 중간을 절반으로 접어 중첩시키는 방식이나 이또한 부피가 여전히 크고 접는 작동에 불편함이 있다. In addition, the conventional folding bike is folded and overlapped in the middle of the frame in half, but this is also bulky and inconvenient for folding operation.

본 발명은 상기한 종래 기술의 문제점을 해소하기 위해 안출된 것으로, 후륜프레임과 메인프레임의 힌지결합부를 형성하되, 후륜프레임을 접었을때 후륜이 전륜과 엇갈려 중첩될 수 있도록 하여 접이 작동이 용이하고, 부피의 축소를 도모할 수 있도록 한 접이식 자전거를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems of the prior art, forming a hinge coupling portion of the rear frame and the main frame, when the rear wheel frame is folded so that the rear wheels can be overlapped with the front wheel to facilitate folding operation, The purpose is to provide a folding bicycle that can be reduced in volume.

상기한 본 발명의 목적은, 안장이 장착된 메인프레임의 전방에 결합된 전륜포크; 상기 전륜포크에 결합된 전륜; 상기 메인프레임의 후방에 결합되는 후륜포크; 상기 후륜포크에 결합된 후륜으로 구성된 자전거에 있어서, 상기 후륜포크는 메인프레임과 제1힌지부로 결합되어 절첩 가능하도록 하되, 상기 제1힌지부는 비스듬하게 형성됨으로써 후륜포크 및 후륜을 접었을때 전륜에 중첩될 수 있도록 한 것을 특징으로 하는 접이식 자전거에 의해 달성될 수 있다.An object of the present invention described above, the front wheel fork coupled to the front of the saddle-mounted mainframe; A front wheel coupled to the front wheel fork; A rear wheel fork coupled to the rear of the mainframe; In the bicycle consisting of the rear wheel coupled to the rear wheel fork, the rear wheel fork is coupled to the main frame and the first hinge to be foldable, the first hinge portion is formed obliquely overlapping the front wheel when the rear fork and the rear wheel folded It can be achieved by a folding bicycle characterized in that it can be.

상기 제1힌지부는, 후륜포크의 선단에 경사지게 형성된 돌출부재; 상기 돌출부재가 삽입되는 끼움홈을 갖도록 메인프레임에 형성된 끼움부재; 상기 끼움홈과 돌출부재를 관통 결합하는 핀을 포함하는 것을 특징으로 한다. The first hinge portion, the projecting member formed to be inclined at the front end of the rear wheel fork; A fitting member formed on the main frame to have a fitting groove into which the protruding member is inserted; It characterized in that it comprises a pin for penetrating the fitting groove and the protruding member.

상기 전륜포크는 메인프레임의 전단에 끼워져 결합되며, 상부에 핸들봉이 결합되고, 하부에는 후방으로 접을 수 있도록 제2힌지부를 갖는 제2전륜포크가 더 형성되며, 상기 제2전륜포크의 하단에 전륜이 결합된 것을 특징으로 한다.The front wheel fork is coupled to the front end of the main frame, the handle bar is coupled to the upper portion, a second front wheel fork having a second hinge portion to be folded rearward is further formed, the front wheel at the bottom of the second front fork It is characterized by a combination.

본 발명에 따르면 후륜프레임과 메인프레임 또는 전륜프레임을 엇갈려서 중첩시킴으로써 부피를 최소화할 수 있는 효과가 있다.According to the present invention, the rear wheel frame and the main frame or the front wheel frame are alternately overlapped, thereby minimizing the volume.

또한 종래에는 메인프레임의 중간에 힌지부가 형성되므로 그 강성이 약화되는 문제점이 야기되었으나 본 발명은 메인프레임의 중간에 힌지부를 형성하지 않음으로써 메인프레임의 강성을 유지할 수 있는 효과가 있다. In addition, in the related art, a hinge portion is formed in the middle of the main frame, which causes a problem of weakening its rigidity. However, the present invention has an effect of maintaining the rigidity of the main frame by not forming a hinge portion in the middle of the main frame.

이하 상기한 각 구성요소에 대해 보다 구체적으로 설명한다.Hereinafter, each component described above will be described in more detail.

상기 메인프레임(6)은 통상의 자전거의 주요 부품으로써 전방에는 핸들봉(600) 및 전륜포크(2)가 결합되고 후방에는 안장(500) 및 후륜포크(4)가 결합되고 하부에는 페달과 크랭크축이 결합된다.The mainframe 6 is a main part of a normal bicycle, the handlebar 600 and the front wheel fork (2) is coupled to the front, the saddle 500 and the rear wheel fork (4) is coupled to the rear, and the pedal and crank at the bottom The shaft is coupled.

이는 이미 공지된 기술사상이며 당업자에게 자명한 기술이므로 이에 대한 상세설명은 생략토록 한다.Since this is already known in the art and known to those skilled in the art, detailed description thereof will be omitted.

상기 후륜포크(4)는 일정 길이를 갖는 봉체 형상으로써 일단부에 후륜(400)이 결합되는 후륜결합부(41)가 형성되고, 타단부는 상단(42) 및 하단(44)으로 분기 형성되며, 하단(44)에는 메인프레임(6)과 결합되는 제1힌지부(H1)가 형성되고, 상 단(42)에는 메인프레임(6)과 결합되는 결합부(C)가 형성된다.The rear wheel fork 4 has a rod shape having a predetermined length, and a rear wheel coupling part 41 to which the rear wheel 400 is coupled to one end is formed, and the other end is branched to the upper end 42 and the lower end 44. The lower end 44 has a first hinge portion H1 coupled to the main frame 6, and the upper portion 42 has a coupling portion C coupled with the main frame 6.

한편 본 발명의 가장 큰 특징은 후륜포크(4)와 메인프레임(6)을 연결하는 제1힌지부(H1)에 있다.On the other hand, the biggest feature of the present invention is the first hinge portion (H1) connecting the rear wheel fork (4) and the main frame (6).

도 3에 나타낸 바와 같이, 제1힌지부(H1)는, 후륜포크(4)의 선단에 경사지게 형성된 돌출부재(410); 상기 돌출부재(410)가 삽입되는 끼움홈(60)을 갖도록 메인프레임(6)에 형성된 끼움부재(62); 상기 끼움홈(60)과 돌출부재(410)를 관통 결합하는 핀(64)으로 구성된다. As shown in FIG. 3, the first hinge portion H1 includes: a protruding member 410 formed to be inclined at the tip of the rear wheel fork 4; A fitting member 62 formed in the main frame 6 to have a fitting groove 60 into which the protruding member 410 is inserted; It consists of a pin 64 through which the fitting groove 60 and the protruding member 410 through.

상기 돌출부재(410)는 도 3에 나타낸 바와 같이, 가상의 수평선을 0°로 가정하였을때 상방으로 경사지게 형성되는데 약 5°~8°의 엇각(θ1)을 갖도록 형성되며 핀(64)이 결합되도록 통공이 형성된다.As shown in FIG. 3, the protruding member 410 is formed to be inclined upward when the virtual horizontal line is assumed to be 0 °, and is formed to have a right angle θ 1 of about 5 ° to 8 °, and the pin 64 is formed. A through hole is formed to engage.

여기서 상기 가상의 수평선을 0°로 가정함은 메인프레임(6) 및 전륜(200)이 직선으로 위치되었을때의 기준 각도이기도 하다.The hypothetical horizontal line is assumed to be 0 °, which is a reference angle when the mainframe 6 and the front wheels 200 are positioned in a straight line.

또한 상기 끼움부재(62)는 돌출부재(410)에 대응되도록 비스듬히 형성되며 그 양측으로는 핀(64)이 결합되는 통공이 형성된다.In addition, the fitting member 62 is formed obliquely so as to correspond to the protruding member 410, and both sides of the fitting member 62 are formed with a through hole to which the pin 64 is coupled.

따라서 후륜포크(4)를 전륜(200)을 향해 회전시키면 돌출부재(410)의 엇각(θ1)에 의해 후륜(400)이 전륜(200)과 부딪치지 않고 일측으로 비스듬하게 접어져서 전륜(200)과 후륜(400)이 중첩될 수 있다.Accordingly, when the rear wheel fork 4 is rotated toward the front wheel 200, the rear wheel 400 is folded obliquely to one side without colliding with the front wheel 200 by the right angle θ 1 of the protruding member 410, and thus the front wheel 200. The rear wheel 400 may overlap.

한편 도 4는 본 발명에 따른 접이식 자전거에서 '제1힌지부'의 다른 예를 나타낸 단면도이다.On the other hand, Figure 4 is a cross-sectional view showing another example of the 'first hinge portion' in the folding bicycle according to the present invention.

도 4에 나타낸 바와 같이, 다른 예에 따른 제1힌지부(H1')는As shown in FIG. 4, the first hinge part H1 ′ according to another example is

후륜포크(4)의 선단에 돌출 형성된 돌출부재(410); 상기 돌출부재(410)가 삽입되는 끼움홈(60)을 갖도록 메인프레임(6)에 형성된 끼움부재(62); 상기 끼움홈(60)과 돌출부재(410)를 관통 결합하되 경사지게 결합된 핀(64')으로 구성된다.A protruding member 410 protruding from the front end of the rear wheel fork 4; A fitting member 62 formed in the main frame 6 to have a fitting groove 60 into which the protruding member 410 is inserted; The fitting groove 60 and the protruding member 410 are coupled through, but are composed of a pin 64 'obliquely coupled.

상기 돌출부재(410)는 후륜포크(4)와 평행되게 직선형태로 형성되며, 상기 끼움부재(62)도 직선형으로 형성된다.The protruding member 410 is formed in a straight line parallel to the rear wheel fork 4, the fitting member 62 is also formed in a straight line.

특히 상술한 첫번째 실시예와 상이한 점은, 상기 돌출부재(410) 및 끼움부재(62)에는 핀(64')이 결합되는 통공이 형성되는데, 상기 통공이 경사지게 형성된다.In particular, the first embodiment is different from the above, the protruding member 410 and the fitting member 62 has a through hole is coupled to the pin 64 'is formed, the through hole is formed to be inclined.

즉, 상기 통공은 도 4에 나타낸 바와 같이, 안장(500)을 향하는 가상의 수직선을 0°로 가정하였을때 좌측으로 약 5°~8°의 엇각(θ2)을 갖도록 경사지게 형성됨으로써 상기 통공에 결합되는 핀(64') 또한 경사를 갖도록 결합된다.That is, as shown in FIG. 4, when the virtual vertical line toward the saddle 500 is assumed to be 0 °, the through hole is formed to be inclined to have a right angle θ 2 of about 5 ° to 8 ° to the left side. The pin 64 'that is to be coupled is also coupled to have a slope.

따라서 이러한 구조에 의해 후륜포크(4)를 전륜(200)을 향해 회전시키면 후륜(400)이 전륜(200)과 부딪치지 않고 일측으로 비스듬하게 접어져서 중첩될 수 있다.Accordingly, when the rear wheel fork 4 is rotated toward the front wheel 200 by the structure, the rear wheel 400 may be folded obliquely to one side without overlapping the front wheel 200.

상술한 2가지 실시예에서 후륜포크(4)의 상단에는 메인프레임(6)과 결합되는 결합부(C)를 형성하고, 상기 결합부(C)에는 통상 자전거의 힌지부에 장착되는 잠금수단(45)이 구비된다.In the above-described two embodiments, a coupling part C coupled to the main frame 6 is formed at the upper end of the rear wheel fork 4, and the coupling part C is usually provided with locking means mounted to the hinge part of the bicycle ( 45).

따라서 후륜포크(4)를 전개시켰을 때 잠금수단(45)에 의해 고정된 상태가 유지될 수 있다.Therefore, when the rear wheel fork 4 is deployed, the state fixed by the locking means 45 can be maintained.

상기 잠금수단(45)의 일 예로는 일정 길이를 갖는 볼트축과, 상기 볼트축의 단부에 힌지결합된 레버로 이루어진 QR레버(Quick Release Lever)를 들 수 있으며, 상기 QR레버를 결합부(C)에 결합시켜 고정된 상태를 유지할 수 있고, 반대로 QR레버를 분리하면 후륜포크(4)의 절첩 작동이 가능하게 된다.An example of the locking means 45 may include a QR lever (Quick Release Lever) consisting of a bolt shaft having a predetermined length and a lever hinged to the end of the bolt shaft, the QR lever is coupled to the coupling portion (C) It can be coupled to the fixed state and, on the contrary, if the QR lever is removed, the rear wheel fork can be folded.

한편 본 발명은 전륜포크(2)에 제2힌지부(H2)를 형성하여 전륜포크(2)가 접힐 수 있도록 하였다.Meanwhile, the present invention forms the second hinge portion H2 on the front wheel fork 2 so that the front wheel fork 2 can be folded.

도 1 및 도 2에 나타낸 바와 같이, 전륜포크(2)는 메인프레임(6)의 전단에 끼워져 결합되며, 상부에 핸들봉(600)이 결합되고, 하부에는 후방으로 접을 수 있도록 제2힌지부(H2)를 갖는 제2전륜포크(22)가 더 형성되며, 상기 제2전륜포크(22)의 하단에 전륜(200)이 결합된다.As shown in Figure 1 and 2, the front wheel fork (2) is fitted into the front end of the main frame (6) is coupled, the handle rod 600 is coupled to the upper portion, the second hinge portion to be folded rearward A second front wheel fork 22 having an H2 is further formed, and the front wheel 200 is coupled to a lower end of the second front wheel fork 22.

제2힌지부(H2)는 전륜포크(2)와 제2전륜포크(22)에 각기 형성되어 상호 결합되는 암,수브라켓과, 상기 암,수브라켓에 결합되는 힌지핀으로 구성된다.The second hinge portion H2 is formed of a front wheel fork 2 and a second front wheel fork 22, respectively, and is formed of a female and male bracket coupled to each other, and a hinge pin coupled to the female and male bracket.

또한 제2전륜포크(22)에는 상기 전륜포크(2)의 하단부에 밀착되도록 걸림턱(221)이 형성된다.In addition, a locking jaw 221 is formed in the second front wheel fork 22 to be in close contact with the lower end of the front wheel fork 2.

따라서 제2전륜포크(22)가 접히면서 그 걸림턱(221)의 상면이 전륜포크(2)의 하단부에 밀착되면서 접히므로 전개상태가 견고하게 된다.Therefore, while the second front wheel fork 22 is folded, the upper surface of the locking jaw 221 is folded in close contact with the lower end of the front wheel fork 2, so that the deployment state is firm.

또한 전륜포크(2)와 제2전륜포크(22)의 결합된 상태를 고정시키기 위해 잠금수단(223)이 더 설치된다.In addition, a locking means 223 is further provided to fix the coupled state of the front wheel fork 2 and the second front wheel fork 22.

즉, 제2전륜포크(22)를 전방을 향해 전개시켜 전륜포크(2)와 결합되도록 한 후 잠금수단(223)을 체결함으로써 견고하게 고정시킬 수 있다.That is, the second front wheel fork 22 may be deployed forward to be coupled with the front wheel fork 2 and then may be firmly fixed by fastening the locking means 223.

이와 반대로 제2전륜포크(22)가 후방을 향하도록 접어서 전륜(200)이 메인프레임(6)의 하부에 위치될 수 있다.On the contrary, the front wheels 200 may be positioned under the main frame 6 by folding the second front wheel forks 22 toward the rear side.

상기 잠금수단(223)은 상술한 QR레버가 적당하나 반드시 이에 한정될 필요는 없다.The locking means 223 is the QR lever described above, but is not necessarily limited thereto.

비록 본 발명이 상기 언급된 바람직한 실시예와 관련하여 설명되어졌지만, 발명의 요지와 범위로부터 벗어남이 없이 다양한 수정 및 변형이 가능한 것은 당업자라면 용이하게 인식할 수 있을 것이며, 이러한 변경 및 수정은 모두 첨부된 청구의 범위에 속함은 자명하다.Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, It is obvious that the claims fall within the scope of the claims.
