Description

과수용 사다리{A Fruit Tree Ladder}Fruit Tree Ladder {A Fruit Tree Ladder}

본 고안은 과수용 사다리에 관한 것으로 보다 상세히는 요철(凹凸)돌기가 형성된 발판(1) 및 보조발판(3)과 붕괴방지용 원추형핀(2)으로 구성된 과수용 사다리에 관한 것이다.The present invention relates to an orchard ladder, and more particularly, to an orchard ladder consisting of a scaffold (1) and an auxiliary scaffold (3) and a conical pin (2) for preventing collapse formed with an uneven protrusion.

일반적으로, 과수용 사다리는 여타의 사다리와 같이 후레임(4)에 평면 돌기형발판, 보조받침대(5)에 평면형 보조발판을 알곤 용접하여 설치하고 후레임(4)과 보조받침대(5) 하단에 4개의 돌기가 있는 핀을 설치하거나 아무런 장치도 하지 않는등의 다양한 형태가 있다.In general, the orchard ladder is installed by welding the flat projection scaffold on the frame 4 and the auxiliary scaffold on the support base 5 like other ladders, and the bottom of the frame 4 and the support base 4 There are various forms, such as installing a dog-prong pin or no device.

그런데, 최근에는 작업의 안전성과 효율 그리고 생산성을 동시에 만족할 수 있도록 점차 표준화되고 있다. 그러나, 평면형 발판과 보조발판은 작업시나 오르내릴때 잘 미끄러지며 특히 진흙이 묻어있는 신발을 신고 작업할 경우 발판에 진흙이 붙어있어 더욱 그렇다. 또한 4개의 돌기가 있는 핀은 평면이 아닌 지면에 완전한 접촉이 이루어 지지 않아 안전성에 문제점이 있었다.However, recently, it is gradually being standardized to satisfy the safety, efficiency and productivity of the work at the same time. However, the flat footing and the auxiliary footing slide well when working or climbing up and down, especially when working with shoes that have mud on them. In addition, the four projection pins have a problem in safety because they do not make a complete contact with the ground rather than a plane.

본 고안의 목적은 과수용 사다리의 발판(1)과 과수 작업시 미끄럼을 방지하여 안전성을 보장하고 부품을 표준화 시켜 원가를 절감하고 작업의 효율성을 보장할 수 있는 과수용 사다리를 제공하기 위한 것이다.The purpose of the present invention is to provide a ladder for overworking ladders that can prevent slippage during overworking and to ensure safety and standardize parts to reduce costs and ensure work efficiency.

본 고안에 따르면, 안전용 발판(1)과 보조발판(3)이 설치되고 작업시 지면에서 미끄러져 사다리의 붕괴를 방지하기 위한 원추형핀(2)이 설치된 것을 특징으로 하는 과수용 사다리가 제공된다.According to the present invention, there is provided an ordinal ladder, characterized in that the safety footrest 1 and the auxiliary footrest 3 are installed and conical pins 2 are installed to prevent the collapse of the ladder by slipping off the ground during work. .

이하, 본 고안의 바람직한 실시예를 첨부한 도면에 의거하여 설명하면 다음과 같다.Hereinafter, described with reference to the accompanying drawings, preferred embodiments of the present invention is as follows.

도 1은 본 고안의 대표 사시도로서 후레임(4)에 요철(凹凸)돌기가 형성된 일자형파이프(1-1)의 평면 부분에 요철(凹凸)돌기가 형성된 U자형파이프(1-2)를 알곤 용접하여 구성된 각각 폭이 상이한 수개의 발판(1)을 적당한 간격으로 알곤 용접하여 설치하고 후레임(4)에 브라켓(6)을 가설하고 파이프핀(7)에 의해 결합된 보조받침대(5)의 중상(中上)부분에 후면 구배진 부분에 요철돌기(3-1)가 형성된 다이캐스팅한 보조발판(3)을 알곤 용접하여 설치하고 후레임(4)과 보조받침대(5) 하단에 사다리를 지상에 적절한 넓이(약60~70도)로 설치할때 안전핀의 역활을 할 수 있도록 도 5에 도시한 바와같이 원뿔부분을 평면 후렌지부분에서 화살표 방향으로 각도를 준 다이캐스팅한 원추형핀(2)을 알곤용접으로 결합하여 구성한 것이다.1 is a representative perspective view of the present invention, argon welding the U-shaped pipe (1-2) is formed in the planar portion of the straight pipe (1-1) in which the uneven projection is formed on the frame (4) Arranged several footrests (1) each having a different width configured by argon welding at appropriate intervals, install the bracket (6) on the frame (4) and the middle of the auxiliary support (5) joined by the pipe pin (7) Install the die-casting auxiliary scaffold (3), which has the uneven protrusion (3-1) formed on the rear slope part in the middle part, by argon welding and install the ladder at the bottom of the frame (4) and the auxiliary support (5) to the appropriate width on the ground. (About 60-70 degrees) to combine the die cast conical pins (2) angled in the direction of the arrow in the direction of the arrow from the flat flange portion as shown in Figure 5 so as to act as a safety pin by argon welding It is made up.

이러한 과수용 사다리는 각종 사다리에 광범위하게 적용할 수 있다.Such an orchard ladder can be widely applied to various ladders.

이상에서와 같이 본 고안에 의하면, 과수용 사다리에 요철(凹凸)돌기형 발판(1)과 다이캐스팅한 보조발판(3)을 설치하고 후레임(4)과 보조받침대(5) 하단에 다이캐스팅한 원추형핀(2)을 가설 하므로서 발판(1)에 진흙등 이물질이 U자파이프(1-2)의 공간으로 흘러내려 이물질이 달라 붙지않아 발의 미끄러짐을 방지하고 화살표 방향으로 각도를 준 원추형핀(2)은 후레임 양쪽과 보조받침대(5)와의 삼각점을 형성되게 해서 안정성을 높여 작업시 사다리의 붕괴를 사전에 예방할 수 있다.As described above, according to the present invention, the concave pins are installed on the ladder for fruit tree by installing the uneven protrusion-type footrest 1 and the die-casting auxiliary footrest 3 and die-casting the bottom of the frame 4 and the auxiliary support 5. By constructing (2), foreign matter such as mud flows into the space of the U-pipe (1-2) on the scaffold (1) to prevent the foreign matter from sticking to the feet and prevents slipping of the feet. By forming a triangular point between both sides of the frame and the auxiliary support (5) to increase the stability can prevent the collapse of the ladder in advance.

또한, 다이캐스팅한 보조발판(3)과 원추형핀(2)을 표준화 시키므로서 생산성을 증대 시켜 원가를 절감하였으며 안전성을 높여 주므로서 과수작업의 효과를 향상 시킬 수 있는 과수용 사다리를 제공할 수 있다.In addition, by standardizing the die-casting auxiliary scaffold (3) and the conical pin (2) to increase the productivity can reduce the cost and increase the safety can provide an orchard ladder that can improve the effect of the fruiting operation.
