Description

뒤보기와 슬라이딩 가능한 시트를 갖는 어린이용 자전거Children's bicycle with rear view and slidable seat
본 발명은 어린이용 자전거에 관한 것으로서, 특히 어린이가 앞보기 및 뒤보기할 수 있도록 시트가 회전할 뿐만 아니라 어린이의 발이 페달이나 발판에 편하게 닿을 수 있도록 어린이의 다리길이에 맞게 시트가 앞뒤로 슬라이딩하게 설치되는 어린이용 자전거에 관한 것이다. The present invention relates to a children's bicycle, and in particular, the seat is rotated to allow the child to front and rear view as well as the seat is installed to slide back and forth according to the child's leg length so that the child's feet can easily touch the pedal or footrest It is about being a children's bicycle.
대한민국 공개특허 제2009-100870호(2009.09.24.공개)에 개시된 자전거 겸용 유모차는 시트가 고정 설치되어 있어 뒤보기가 불가능하다는 단점이 있다. 이에 대한민국 등록특허 제1268358호(2013.06.22.등록)에서는 시트를 뒤보기 가능하게 설치함으로써, 어린이(유아 포함)가 뒤에 있는 보호자와 눈을 맞출 수 있도록 하여 어린이에게 안정감을 주고 또한 보호자의 입장에서는 어린이의 보호관찰이 용이하도록 한 뒤보기 가능한 자전거가 개시되었다. Bicycle combined stroller disclosed in the Republic of Korea Patent Publication No. 2009-100870 (2009.09.24. Publication) has a disadvantage that the back is impossible because the seat is fixed. Accordingly, Republic of Korea Patent No. 1268358 (registered on June 22, 2013) installs the seat so that the child (including the infant) can make eye contact with the guardian behind and gives a sense of stability to the child. A rearviewable bicycle has been disclosed to facilitate the probation of children.
그러나 상술한 종래의 뒤보기 가능한 자전거는 시트를 앞보기와 뒤보기 방향으로 회전시킬 때에 등받이가 자전거의 앞프레임이나 뒷프레임에 걸리기 때문에 시트를 자전거의 앞프레임과 뒷프레임으로부터 어느 정도 떨어지게 위치시킬 수밖에 없다. 그래서 첫째, 시트를 앞보기 방향으로 회전시켰을 때에 시트가 전륜에서 멀리 위치하여 어린이의 발이 페달이나 발판에 제대로 닿지 못하는 문제가 발생하고, 둘째, 시트의 원활한 회전을 위하여 등받이가 자전거의 앞프레임이나 뒷프레임에 걸리지 않도록 등받이의 기울기에 제한이 가해질 수밖에 없어 등받이를 눕히는데 한계가 있을 수밖에 없었다. However, in the conventional rear viewable bicycle described above, when the seat is rotated in the front and rear directions, the backrest is caught by the front frame or the rear frame of the bicycle, so the seat can be positioned some distance from the front frame and the rear frame of the bicycle. none. Firstly, when the seat is rotated in the forward direction, the seat is located far away from the front wheel, so that the child's foot does not touch the pedal or the footrest properly. The inclination of the backrest must be restricted so as not to get caught in the frame, so there was a limit in laying the backrest.
따라서 본 발명이 해결하고자 하는 과제는, 시트가 앞보기와 뒤보기 방향으로 회전가능 할 뿐만 아니라 앞뒤로 슬라이딩 가능하게 함으로써, 시트가 회전될 때에 등받이에 의해 그 회전이 제한을 받는 것이 덜하고, 또한 어린이의 다리길이에 맞추어 시트를 적절하게 위치시킬 수 있으며, 등받이의 기울기 범위를 더욱 넓게 할 수 있는 어린이용 자전거를 제공하는 데 있다. Accordingly, the problem to be solved by the present invention is that the seat is not only rotatable in the front and back directions, but also slides back and forth, so that the rotation is less restricted by the backrest when the seat is rotated, and also the children The present invention provides a children's bicycle capable of properly positioning the seat according to the leg length of the body and further extending the inclination range of the backrest.

도 10은 슬라이딩블록(220)의 슬라이딩 동작원리를 설명하기 위한 도면이다. 도 8 및 9와 결부하여 도 10을 참조하면, 슬라이딩버튼(310)을 누르지 않은 평상시에는 탄성수단(314)에 의하여 슬라이딩버튼(310)이 바깥쪽으로 밀려나지만 이탈방지핀(611)이 가이드장공(311)의 안쪽끝단에 걸리므로 슬라이딩버튼(310)이 슬라이딩버튼삽입홈(225)에서 완전히 이탈되어 빠져버리지는 않는다. 이 때 통과홈(312)이 요철레일(420)과 어긋나게 위치하여 철부(422)에 슬라이딩버튼(420)이 걸리게 되므로 슬라이딩블록(220)이 활주되지 못한다. 10 is a view for explaining the sliding operation principle of the sliding block 220. Referring to FIG. 10 in conjunction with FIGS. 8 and 9, the sliding button 310 is pushed outward by the elastic means 314 in the usual time when the sliding button 310 is not pressed. Since it is caught by the inner end of 311, the sliding button 310 is completely separated from the sliding button insertion groove 225 does not fall out. At this time, since the through groove 312 is offset from the uneven rail 420, the sliding button 420 is caught on the convex portion 422, so that the sliding block 220 cannot slide.
슬라이딩버튼(310)을 누르면 탄성수단(314)이 압착되면서 통과홈(312)이 요철레일(420)의 위치로 이동하게 되고 그러면 철부(422)가 통과홈(312)을 지나갈 수 있으므로 슬라이딩블록(220)의 활주가 이루어진다. When the sliding button 310 is pressed, the elastic means 314 is squeezed so that the passage groove 312 moves to the position of the uneven rail 420, and then the convex portion 422 can pass through the passage groove 312 so that the sliding block ( A slide of 220 is made.
이때, 이탈방지핀(611, 612)이 이탈방지핀삽입장공(440)에 삽입되어 있는 상태이기 때문에 슬라이딩블록(220)의 활주가 이탈방지삽입장공(440)의 길이 내에서 이루어지므로 슬라이딩블록(220)이 과도하게 활주되어 가이드판(400)에서 이탈되는 것이 방지된다. At this time, since the release preventing pins 611 and 612 are inserted into the release preventing pin insertion hole 440, the sliding block 220 slides because the slide is made within the length of the release preventing insertion hole 440. 220 is excessively slid to prevent the departure from the guide plate 400.
도 11은 회전블록(230)을 설명하기 위한 도면이다. 도 8 및 9와 결부하여 도 11을 참조하면, 회전블록(230)의 회전축(231)이 슬라이딩블록(220)의 회전축삽입공(223)에 회전가능하게 삽입되고, 바퀴거치부(224)에 회동바퀴(510)가 설치되어 있으므로 회전블록(230)은 슬라이딩블록(220) 상에서 회전할 수 있게 된다. 이 때 회전블록(230)의 회전을 통제하기 위하여 회전버튼(320)이 슬라이딩블록(220)의 측면에 형성된 회전버튼삽입홈(325)에 빗장처럼 삽입설치된다. 11 is a view for explaining the rotary block 230. Referring to FIG. 11 in conjunction with FIGS. 8 and 9, the rotating shaft 231 of the rotating block 230 is rotatably inserted into the rotating shaft insertion hole 223 of the sliding block 220, and the wheel mounting portion 224. Since the rotation wheel 510 is installed, the rotary block 230 may rotate on the sliding block 220. At this time, in order to control the rotation of the rotary block 230, the rotary button 320 is inserted into the rotary button insertion groove 325 formed on the side of the sliding block 220 like a latch.
회전블록(230)의 밑면에는 중심에서 바깥방향으로 움푹 들어간 회전방지홈(235)이 원주 상으로 배열되도록 복수개 형성되며, 회전버튼(320)에는 회전방지홈(235)에 끼워지도록 회전걸림턱(321)이 위로 돌출되게 형성된다. 회전버튼(320)의 끝단에는 탄성수단(324)이 설치된다. The bottom surface of the rotary block 230 is formed in a plurality of rotation preventing grooves 235 recessed from the center to the outer circumference is formed in a circumferential direction, the rotary button 320 to the rotation locking jaw (fit to the rotation preventing groove 235) 321 is formed to protrude upward. An elastic means 324 is installed at the end of the rotary button 320.
도 12는 회전블록(230)의 회전 동작원리를 설명하기 위한 도면이다. 도 8, 9, 11과 결부하여 도 12를 참조하면, 회전버튼(320)을 누르지 않은 평상시에는 탄성수단(324)에 의하여 회전버튼(320)이 바깥쪽으로 밀려나지만 회전걸림턱(321)이 회전방지홈(235)의 바깥쪽단에 걸리므로 회전버튼(320)이 회전버튼삽입홈(325)에서 완전히 이탈되어 빠져버리지는 않는다. 이 때 회전걸림턱(321)이 회전방지홈(235)에 걸려있는 상태이기 때문에 회전블록(230)은 회전되지 못한다. 12 is a view for explaining the principle of rotation of the rotary block 230. Referring to FIG. 12 in conjunction with FIGS. 8, 9, and 11, when the rotary button 320 is not pressed normally, the rotary button 320 is pushed outward by the elastic means 324, but the rotation locking jaw 321 rotates. Since the outer end of the prevention groove 235 is caught, the rotary button 320 is completely separated from the rotary button insertion groove 325 and does not fall out. At this time, because the rotating locking jaw 321 is caught in the rotation preventing groove 235, the rotating block 230 cannot be rotated.
회전버튼(320)을 누르면 탄성수단(324)이 압착되면서 회전걸림턱(321)이 회전방지홈(235)의 안쪽방향으로 이탈되고 따라서 회전블록(230)이 회전축(231)을 축으로 하여 회전할 수 있게 된다. When the rotary button 320 is pressed, the elastic means 324 is squeezed and the rotation catching jaw 321 is released in the inward direction of the anti-rotation groove 235, and thus the rotary block 230 rotates about the axis of rotation 231. You can do it.
도 13은 회전블록(230)과 슬라이딩블록(220)의 다른 결합예를 설명하기 위한 측단면도이다. 도 13에 도시된 바와 같이, 회전블록(230)의 회전축(31)이 슬라이딩블록(220)의 회전축삽입공(23)에 회전가능하게 삽입되고, 회전블록(230)의 아랫면에 멈춤돌기(1)가 회전축삽입공(23)의 둘레에 원주 상으로 배열되도록 돌출형성되며, 슬라이딩블록(220)의 윗면에 멈춤돌기(1)가 끼워지는 멈춤홈(2)이 형성될 수 있다. 멈춤돌기(1)와 멈춤홈(2)은 이와 반대의 위치에 설치되어도 무방하다. 13 is a side cross-sectional view for explaining another coupling example of the rotary block 230 and the sliding block 220. As shown in FIG. 13, the rotation shaft 31 of the rotation block 230 is rotatably inserted into the rotation shaft insertion hole 23 of the sliding block 220, and the stop protrusion 1 is disposed on the bottom surface of the rotation block 230. ) Is formed to protrude so as to be arranged circumferentially around the rotation axis insertion hole 23, a stop groove (2) into which the stop projection (1) is fitted on the upper surface of the sliding block 220 may be formed. The stop projection 1 and the stop groove 2 may be installed at positions opposite thereto.
이 결합예의 경우에는 회전블록(230)의 자체무게에 의하여 멈춤돌기(1)가 멈춤홈(2)에 끼워지기 때문에 평상시에는 회전블록(230)의 회전이 이루어지지 않지만, 멈춤돌기(1)가 멈춤홈(2)에서 빠지도록 회전블록(230)을 인위적으로 들어올리는 경우에는 회전블록(230)의 회전이 가능하게 된다. 이 때 멈춤돌기(1)가 멈춤홈(2)에서 완전히 이탈되어 버리지 않도록 멈춤돌기(1)의 끝단에는 옆으로 걸림턱(31a)이 돌출형성되고, 멈춤홈(2)의 입구는 걸림턱(31a)이 빠지지 않게 좁아야 한다.  In this coupling example, since the stop protrusion 1 is fitted into the stop groove 2 by the weight of the rotary block 230, the rotation block 230 is not normally rotated, but the stop protrusion 1 is When the rotary block 230 is artificially lifted to be pulled out of the stop groove 2, the rotation of the rotary block 230 is possible. At this time, so that the stop projection (1) is not completely separated from the stop groove (2), the end of the stop projection (1) has a locking jaw (31a) protruding sideways, the inlet of the stop groove (2) is a locking jaw ( 31a) should be narrow so as not to fall out.
상술한 바와 같이, 본 발명에 의하면, 시트블록(200)이 앞보기와 뒤보기 방향으로 회전가능 할 뿐만 아니라 앞뒤로 슬라이딩 가능하기 때문에, 시트블록(200)이 회전될 때 등받이(240)에 의해 그 회전이 제한을 받는 것이 덜하고, 또한 어린이의 다리길이에 맞추어 시트블록(200)을 적절하게 위치시킬 수 있으며, 등받이(240)의 기울기 범위를 더욱 넓게 할 수 있다. As described above, according to the present invention, since the seat block 200 is not only rotatable in the front and rear view directions, but also slides back and forth, the seat block 200 is rotated by the backrest 240 when the seat block 200 is rotated. The rotation is less restricted, and the seat block 200 can be properly positioned according to the leg length of the child, and the inclination range of the backrest 240 can be further widened.
