Description

바퀴 접이식 손수레{A HANDCART OF WHEEL FOLDING}Wheel folding cart {A HANDCART OF WHEEL FOLDING}

본 발명은 바퀴 접이식 손수레에 관한 것으로서, 더욱 상세하게는 과수원이나 비닐하우스 등에서 농작물을 재배하거나 수확할 때 사용하는 손수레의 뒷바퀴를 접거나 펼 수 있도록 하여 보다 적은 힘으로 안정된 운반이 가능하도록 한 바퀴 접이식 손수레에 관한 것이다.The present invention relates to a wheel folding cart, and more particularly, to fold or unfold the rear wheel of the wheelbarrow used for growing or harvesting crops in an orchard or a plastic house, so that the wheel is foldable for stable transport with less power. It's about a cart.

일반적으로 과수원이나 비닐하우스 등에서 사용하는 손수레는 운반용 바퀴가 앞쪽에 1개 형성되거나 앞쪽 양측에 2개 형성되며, 뒤쪽에는 손수레 받침구가 형성된 것으로 운반시 손잡이를 잡고 앞쪽 바퀴에만 의존하여 이동하므로 주행이 불안정하고 무게 중심을 잡기 힘들었다.In general, carts used in orchards or plastic houses are formed with one wheel on the front or two on both sides of the front, and a cart support is formed on the back. It was unstable and hard to grasp the center of gravity.

상기 손수레는 손잡이를 잡고 위로 들어 앞쪽 바퀴에만 의존하여 앞으로 밀면서 운반하기 때문에 손과 팔 및 허리에 무리한 힘이 가해져 피로가 가중되는 단점이 있었다.The handcart has a drawback of increasing fatigue due to excessive force applied to the hands, arms, and waist because the cart is carried forward while the handle is pushed upwards depending on the front wheel.

상기 손수레의 단점을 보완하기 위하여 뒤쪽에도 바퀴를 형성한 경우, 비탈진 곳 등에서 물건을 싣거나 내릴 때 손수레가 미끄러져 내리는 문제점이 있었다.When wheels were formed on the rear side to compensate for the disadvantages of the cart, there was a problem that the cart slipped down when loading or unloading items in the slope.

본 발명은 상기 문제점을 해결하기 위하여 안출한 것으로, 손수레 운반시 앞바퀴와 함께 접이식 뒷바퀴를 사용하여 보다 안정되고 원활한 주행이 이루어질 수 있도록 하고, 손수레에 물건을 싣거나 내릴 때에는 뒷바퀴를 접어 받침구가 지면에 닿도록 함으로써 움직이지 않고 고정되도록 하여 사용상 편리함을 제공하는 데 있다.The present invention has been made to solve the above problems, by using a folding rear wheel with the front wheel when transporting the cart to make a more stable and smooth running, when loading or unloading the wheel in the rear wheel folding the support It is to provide convenience in use by being fixed without moving by touching to.

본 발명은 상기 목적 달성을 위하여 손수레의 주행이 안정되도록 손잡이가 형성된 적재대의 뒤쪽에 접이식 뒷바퀴를 구비하여 손수레 운반시에는 뒷바퀴를 펴고, 물건을 싣거나 내릴 때에는 받침구가 지면에 닿도록 하여 손수레를 고정하는 수단을 강구하였다.The present invention has a folding rear wheel on the back of the loading table formed with a handle so that the running of the cart is stable to achieve the above object, when carrying the cart, spread the rear wheel, when loading or unloading the trolley to reach the ground Means for fixing were taken.

상술한 본 발명의 손수레는 이동시 앞바퀴와 함께 접이식 뒷바퀴를 사용하여 보다 안정되고 원활하며 편안한 운반을 할 수 있고, 물건을 싣고 내릴 때에는 뒷바퀴를 접어 받침구가 지면에 닿도록 함으로써 손수레가 미끄러지지 않고 고정되도록 하는 효과가 있다.The above-described cart of the present invention can be more stable, smooth and comfortable carrying by using the foldable rear wheel with the front wheel when moving, and when loading and unloading, the rear wheel is folded so that the support can touch the ground so that the cart can be fixed without slipping. It is effective.

A plurality of height adjustment holes 26b are formed on both sides in the shape of a ruler.

상기 바퀴접이장치(12)를 구성하는 접이구 홀더(15)에 접이구(16)를 삽입하되 상기 접이구(16)의 양측 괘정홈(24)속에 지지가 되도록 괘해정핀 당김줄(21) 한쪽 끝이 고정된 괘해정핀(18)을 삽입한 상태에서 상기 접이구 홀더(15)에 형성된 회전축 지지구멍(25a)과 괘정홈(24) 아래쪽의 회전축 지지구멍(25b)을 통과하도록 접첩 회전축(19)을 삽입하여 회전자재토록 너트체결하여 지지한다.Inserting the foldable opening 16 into the foldable holder 15 constituting the wheel folding device 12, the pinned pin pull string 21 so as to be supported in both side defining grooves 24 of the foldable opening 16 The folding rotary shaft passes through the rotary shaft support hole 25a formed in the folding-hole holder 15 and the rotary shaft support hole 25b below the locking groove 24 in a state where the fixed locking pin 18 having one end inserted therein is inserted. Insert (19) and tighten the nut to support the rotor.

상기 접이구(16)에는 바퀴 높낮이조절구(17)를 삽입하여 상기 접이구(16)에 형성된 높낮이조절구멍(26a)과 바퀴 높낮이조절구(17)에 다수 개 형성된 높낮이조절구멍(26b)을 맞추어 높낮이조절볼트(20)를 너트로 체결하여 고정한다.The height adjustment hole 26a formed in the folding hole 16 and the height adjustment hole 26b formed in the wheel height adjusting opening 17 are inserted into the folding hole 16 by the wheel height adjusting opening 17. Fasten the height adjustment bolt 20 with a nut.

또한, 상기 접이구 홀더(15)와 접이구(16)의 한쪽 또는 양쪽 측면에는 인장스프링(28)을 나사못 등으로 각각 걸어 뒷바퀴(13)를 접었다가 펼 때 상기 늘어났던 인장 스프링(28)의 당기는 힘에 의해 상기 접이구(16)가 수직으로 쉽게 세워질 수 있도록 하였다.In addition, one or both sides of the foldable holder 15 and the foldable opening 16 are respectively pulled by the tension spring 28 by a screw or the like to fold the rear wheel 13 and pull out the stretched tension spring 28. By means of force, the foldable opening 16 could be easily erected vertically.

그리고 상기 괘해정핀(18)에 한쪽 끝이 고정된 괘해정핀 당김줄(21)은 레버(6a)에 연결되고, 접이구(16)의 배면 상단에 형성된 접이구 당김줄 인출홈(27)을 통과하여 한쪽 끝이 걸림핀(29)에 고정된 접이구 당김줄(22)은 레버(6b)에 연결된다.And the pinned pin pull string 21, one end of which is fixed to the pinned pin 18, is connected to the lever 6a, the folding pin pull-out groove 27 formed on the top of the back of the folding port 16 The fold pull wire 22, one end of which is fixed to the locking pin 29, is connected to the lever 6b.

손수레(1)에 물건을 싣거나 내리기 위해 받침구(8a)(8b)를 지면에 맞닿도록 할 때에는 양측 핸들(7a)(7b)의 손잡이(5a)(5b)에 구비된 레버(6a)를 잡으면 상기 레버(6a)와 괘해정핀 당김줄(21)로 연결된 괘해정핀(18)이 접이구(16)의 상부 양측 괘해정홈(24) 위로 들리면서 접이구 홀더(15)의 하부 양측에 형성된 해정홈(23) 위로 빠지게 되고, 이때 레버(6b)를 잡으면 상기 레버(6b)와 연결된 접이구 당김줄(22)이 당겨지면서 상기 접이구 당김줄(22)의 한쪽 끝이 고정된 걸림핀(29)에 의해 접이구(16)와 결합된 바퀴 높낮이조절구(17)에 장착된 뒷바퀴(13)가 상기 접이구 홀더(15)와 접이구(16)에 결합된 접철 회전축(19)을 중심으로 뒤로 접히게 되어 받침구(8a)(8b)가 지면에 닿게 되므로 손수레(1)는 미끄러지지 않고 고정된다.When bringing the support openings 8a and 8b into contact with the ground for loading or unloading the items on the cart 1, the levers 6a provided on the handles 5a and 5b of both handles 7a and 7b are used. When holding, the ruler pin 18 connected to the lever 6a and the ruler pin pull string 21 is lifted over the upper both side ruler grooves 24 of the fold opening 16, and both sides of the bottom of the fold holder 15 are lower. It is pulled over the release groove 23 formed in the, and when the lever 6b is grasped, the folding tug 22 connected to the lever 6b is pulled and one end of the folding tug 22 is fixed. The rear wheel 13 mounted on the wheel height adjusting device 17 coupled with the folding hole 16 by the pin 29 is folded folding shaft 19 coupled to the folding hole holder 15 and the folding hole 16. Since the backrest is folded around the base (8a) (8b) is in contact with the ground, the cart (1) is fixed without slipping.

손수레(1)의 운반을 위해서는 접었던 뒷바퀴(13)를 펴 주어야 하는데, 이때에는 양측 손잡이(5a)(5b)를 잡고 위로 살짝 들어주면서 접철 회전축(19)을 중심으로 뒤로 접혔던 접이구(16)와 뒷바퀴(13)가 접이구 홀더(15)와 접이구(16) 사이에 형성된 인장스프링(28)의 당기는 힘에 의해 수직으로 세워지면서 상기 접이구(16)가 접이구 홀더(15)에 삽입되고, 이때 손잡이(5a)의 아래쪽에 구비된 레버(6a)를 놓아주면 상기 레버(6a)와 괘해정핀 당김줄(21)로 연결된 괘해정핀(18)이 접이구 홀더(15)와 접이구(16)에 형성된 괘/해정홈(23)(24)을 결속하게 되어 뒷바퀴(13)가 펴져 손수레(1)를 쉽고 편리하게 운반할 수 있다.
In order to transport the cart 1, the folded rear wheels 13 should be extended. At this time, the folding wheels 16 folded back about the folding axis 19 while holding the handles 5a and 5b on both sides and slightly lifting them up. And the rear wheel 13 are erected vertically by the pulling force of the tension spring 28 formed between the fold holder 15 and the fold opening 16 and the fold opening 16 is connected to the fold holder 15. When the lever 6a provided at the bottom of the handle 5a is released, the locking pin 18 connected to the lever 6a and the locking pin pull string 21 is connected to the folding holder 15. The locking / unlocking grooves 23 and 24 formed in the folding port 16 are bound so that the rear wheels 13 can be extended to easily and conveniently carry the cart 1.
