본 발명은 화물차의 적재함을 덮어서 적재물이 날리는 것을 방지하기 위한 화물차 적재함덮개의 자동개폐장치에 관한 것으로, 특히 덮개를 제1덮개부와 제2덮개부로 이등분하고, 상기 제2덮개부를 제2덮개절첩수단에 의해 절첩시켜서 개폐될 수 있도록 하는 화물차 적재함덮개의 자동개폐장치에 관한 것이다.The present invention relates to an automatic opening and closing device of a truck loading box cover to cover the loading box of the truck to prevent the load from flying, and in particular, the cover is divided into a first cover part and a second cover part, and the second cover part is folded in a second cover part. The present invention relates to an automatic opening and closing device for a van loading box cover, which is folded and opened by means.

종래의 모든 화물차 적재함의 덮개는 제5도에 도시한 바와 같이 바(bar)에 고정된 포장지지틀과 상기 포장지지틀과 바에 의해 지지되는 포장으로 이루어지는 구조이고, 상기 바는 회동축에 고정되어 모터의 구동에 의해 270° 회동시켜 적재함을 개폐시키는 매우 단순한 구성인 것이다. 그의 레일과 체인등을 이용한 다수의 방법이 있긴 하나 본 발명과 비교할 만한 구성이 아니므로 언급을 생략한다.Covers of all conventional vans loading box is a structure consisting of a packing support frame fixed to a bar (bar) and a package supported by the bar and the support frame as shown in Figure 5, the bar is fixed to the pivot It is a very simple configuration that opens and closes the loading box by rotating the motor 270 ° by driving the motor. Although there are a number of methods using the rails and chains thereof, the description is omitted because it is not comparable to the present invention.

그러나 상기한 덮개는 화물차 적재함의 가로폭이 약 2.4m 정도이므로 한쪽 덮개의 너비는 1.2m가 되어 화물차 측면 적재함에 상기 덮개를 설치할 경우 회전반경이 커 안전사고의 우려가 있고, 전선등의 지형지물의 영향을 받으며, 또한 덮개가 넓은 반경으로 회전하게 되어 회동축에 걸리는 하중이 커 모터에 상당한 부하가 걸리고 불필요하게 큰용량의 모터를 필요로 하게 되는 비경제적인 폐단을 갖는다. 또한 덮개를 사용하지 않을 때에는 덮개가 차량의 적재함 측면에 매달러 있게 되는데 이때 덮개가 뒷바퀴부분까지 내려오게 되어 차량의 뒷부분에 사각지대가 형성하는 폐단과 운행시에는 넓은 면적 때문에 공기의 저항을 크게 받게 되므로 소음 및 포장의 파손이 심한 폐단을 갖는다.However, since the width of the cover is about 2.4m, the width of the cover is about 1.2m, and the cover is installed at the side of the truck so that the radius of rotation is large, which may cause a safety accident. It is also affected, and the cover rotates to a wide radius, so that the load on the rotating shaft is large, which imposes a considerable load on the motor and unnecessarily requires a large capacity motor. In addition, when the cover is not used, the cover is placed on the side of the loading box of the vehicle every dollar, and the cover is lowered to the rear wheel part, and the air is largely resisted due to the closed area formed by the blind area at the rear part of the vehicle and the large area when driving. Therefore, the noise and breakage of the packaging is severe.

특히 종래의 덮개는 구조상 회동축이 적재함 상단에 위치할 수 밖에 없는 문제점을 안고 있는 것이므로 페이로다 또는 포크레인의 화물적재 작업시 장비의 바켓에 의해 축이 자주 파손되는 단점과 적재량이 많게 되면 덮개가 완전히 덮어주질 못하게 되므로 덮개의 중간부분은 들리게 되어 결국 덮이지 못하는 부분의 적재물은 날리는 폐단도 갖는 것이다.In particular, the conventional cover has a problem that the rotating shaft has to be located at the top of the loading box in structure, so that the shaft is frequently damaged by the bucket of the equipment during the payload or payload of the fork-lane, Since the cover can not be covered, the middle part of the cover is lifted up, so the load of the uncovered part also has a closed end.

이처럼 사각날개형태를 가지는 종래의 화물차 적재함덮개는 상당한 문제점을 노출하고 있음에도 불구하고, 일단 구조가 간단하고, 장착이 용이하며, 설치비용이 저렴하여 가장 널리 보급되어지는 실정이다.As described above, although the conventional van loading box cover having a quadrangular wing shape exposes a considerable problem, the structure is simple, the installation is easy, and the installation cost is low.

따라서 본 발명은 종래의 적재함덮개가 가지는 문제점을 완전히 해결하면서도 종래의 덮개에 비해 설치비용도 그다지 차이가 나지않는 혁신적인 구조를 갖는 덮개를 제공하기 위한 것이다.Accordingly, the present invention is to provide a cover having an innovative structure that completely solves the problems of the conventional shipping box cover, but does not differ much compared to the conventional cover.

즉 본 발명 적재함덮개는 1.2m 정도의 너비를 갖는 하나의 포장지지틀로 이루어진 종래의 덮개를 이등분시켜 제1덮개부와 제2덮개부로 구분하고, 제2덮개부는 제1덮개부를 지지하는 바의 끝단에 회동가능토록 결합시킨 뒤, 상기 제2덮개부를 3개의 작동봉으로 이루어지는 제2덮개절첩수단에 의해 절첩되도록 구성되어짐을 특징으로 한다.In other words, the present invention compartment cover is divided into a first cover part and a second cover part by dividing the conventional cover consisting of one packaging support frame having a width of about 1.2m, the second cover part of the bar supporting the first cover part After coupling so as to be rotatable at the end, characterized in that the second cover portion is configured to be folded by a second cover folding means consisting of three operating rods.

이하, 본 발명의 구성의 첨부도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings of the configuration of the present invention.

제1도는 본 발명의 전체구성을 보인 사시도로써 본 발명 적재함덮개는 크게 제1덮개부(10)와, 상기 제1덮개부를 구동하기 위한 구동수단과 제1덮개부의 상단에 회동가능토록 결합되는 제2덮개부(20)와, 상기 제2덮개부를 절첩시킬 수 있는 제2덮개부절첩수단(40)으로 이루어진다.1 is a perspective view showing the overall configuration of the present invention is a loading box lid of the present invention is largely coupled to the first lid portion 10, the driving means for driving the first lid portion and the upper end of the first lid portion to be rotatable The second cover part 20 and the second cover part folding means 40 capable of folding the second cover part.

상기 제1덮개부(10)는 바(4)와 바축(5)으로만 구성되며, 따라서 종래의 덮개와는 다음과 같은 구성의 차이를 가지게 된다. 즉 종래의 덮개는 제5도와 같이 상기 바(4)에 포장지지틀(C)이 직접 결합되어 상기 포장지지틀고 회동축(3) 사이에포장(A)를 쳐 덮개가 형서오디지만, 본 발명의 제1덮개부(10)는 바(4)와 바축(5)으로 구성되어지므로 포장(A)은 제2덮개부(20)의 포장지지틀(21)과 회동축(3) 사이에 쳐서 덮개를 형성하게 된다.The first cover part 10 is composed only of the bar 4 and the bar shaft 5, and thus has a difference in configuration as follows from the conventional cover. That is, the conventional cover is a packaging support frame (C) is directly coupled to the bar (4) as shown in FIG. Since the first cover portion 10 of the bar 4 and the bar shaft 5 is composed of the packing (A) is struck between the packing support frame 21 and the rotating shaft (3) of the second cover portion 20 The cover will be formed.

여기서 상기 바(4)에는 절곡부(4a)를 형성하므로써 종래의 바처럼 적재함 상단에 회동축(3)이 형성되질 않고 적재함 측면에 설치된다 하더라도 절곡부(4a)에 의해 적재함의 모서리를 피해 바(4)가 적재함 위에서 수평을 유지할 수 있도록 하는 것이다.Here, the bar 4 is formed by the bent portion 4a so that the pivot shaft 3 is not formed at the upper end of the loading box like the conventional bar, even if the side of the loading box is installed on the side of the loading box to avoid the corner of the loading box by the bar 4a. (4) to be level on the loading bin.

또 상기 제1덮개부(10)의 구동수단은 차량 적재함(B)의 일측에 설치되는 모터(1)와, 상기 모터에 의해 연결되는 회동축(3)과, 상기 회동축을 차량의 적재함 측면에 고정되어 지지하는 브라켓트(2)에 의해 구성되어진다. 이는 종래의 덮개구동수단과 구성이 동일하나, 다만 브라켓트(2)를 적재함 상단에 설치하지 않고 적재함 측면에 설치한다는 차이를 갖는다. 이는 이미 설명한 바와 같이 회동축(3)이 적재함 상단에 설치될 경우 페이로다 또는 포크레인 등의 버켓에 의해 쉬 손상되어짐을 방지하기 위한 것이다.In addition, the driving means of the first cover part 10 is a motor 1 installed on one side of the vehicle loading box (B), a rotating shaft (3) connected by the motor, and the side of the loading box of the vehicle It is composed of a bracket (2) fixed to and supported by. This is the same configuration as the conventional cover driving means, except that the bracket (2) is installed on the side of the loading box rather than the top of the loading box. As described above, this is to prevent the shaft from being easily damaged by a bucket such as a payloader or a fork lane when the rotating shaft 3 is installed at the top of the loading box.

또 제2덮개부(20)는 포장지지틀(21)과, 포장(A)과, 바(4)의 포장지지틀(21)을 연결하여 제2덮개부(20)의 절첩을 용이하기 하기 위한 스프링(6)으로 구성되어진다. 상기 제2덮개부(20)의 후방에는 후방덮개부(30)가 형성되어 있으며, 상기 후방덮개부는 제2덮개부에 힌지부(31)에 의해 회동가능토록 결합되며, 일정각을 유지할 수 있도록 하는 스프링(32)을 제2덮개부와 후방덮개부 사이에 구성하므로써 절첩된 상태에서는 제2덮개와 함께 곧게 퍼져있다가 적재함을 덮개 될 경우에는 스프링(32)의 탄발력에 의해 약간 절곡되면서 적재함 상단의 높이에 의해 약간 낮은 적재함후방을 완벽하게 커버할 수 있도록 하는 것이다.In addition, the second cover part 20 connects the packing support frame 21, the packing A, and the packing support frame 21 of the bar 4 to facilitate folding of the second cover part 20. It is composed of a spring (6) for. A rear cover part 30 is formed at the rear of the second cover part 20, and the rear cover part is coupled to the second cover part by a hinge part 31 so as to be rotatable, and to maintain a constant angle. When the spring 32 is configured between the second cover portion and the rear cover portion, it is spread along with the second cover in the folded state, and when the lid is covered, it is bent while being slightly bent by the elasticity of the spring 32. The height of the top makes it possible to completely cover the rear of the slightly lower loading compartment.

상기 제2덮개부(20)는 바(4)의 축(5)에 회동가능토록 결합되는 제2덮개절첩수단(40)의 제3작동봉(45)에 고정결합되며, 이는 본 발명의 매우 중요한 구성이므로 이를 자세히 설명하기로 한다.The second cover part 20 is fixedly coupled to the third actuating rod 45 of the second cover folding means 40 which is pivotally coupled to the shaft 5 of the bar 4, which is a very high aspect of the present invention. Since it is an important configuration, it will be described in detail.

즉 제2덮개부(20)의 포장지지틀(21)의 하부는 제3작동봉(45)의 포장지지틀 고정부(45b)에 결합되며, 상기 포장지지틀 고정부를 지지하는 제2덮개절첩수단(40)에 의해 펼쳐지기도, 절첩되기도 하는 것이다. 상기 제2덮개절첩수단(40)의 구성은 다음과 같다. 적재함의 측면에 고정되어 상기 제2덮개절첩수단을 지탱하는 브라켓트(41)와, 상기 브라켓트에 히동가능토록 연결되며, 양단에는 힌지부(43)가 형성되고, 중간에 절곡부(42a)를 구비하는 제1작동봉(42)과, 상기 제1작동봉에 연결되고 역시 양단에 힌지부가 형성되고 중간부에 절곡부(44a)와 길이조절구(44b)를 구비하는 제2작동봉(44)과, 상기 제2작동봉에 연결되고 일단에는 힌지부가, 타단에는 포장지지틀 고정부(45b)가, 중간부에는 바축(5)에 회동가능토록 결합되는 바축결합부(45a)를 구비하는 제3작동봉(45)로 이루어진다.That is, the lower part of the packing support frame 21 of the second cover part 20 is coupled to the packing support frame fixing part 45b of the third operating rod 45, and a second cover supporting the packing support frame fixing part. It may be unfolded or folded by the folding means 40. The second cover folding means 40 is configured as follows. A bracket 41 fixed to the side of the loading box to support the second cover folding means, and connected to the bracket so as to be movable, and hinges 43 are formed at both ends, and a bent portion 42a is provided in the middle. A second operating rod 44 connected to the first operating rod 42 and having a hinge portion at both ends and having a bent portion 44a and a length adjusting port 44b in the middle portion thereof. And a bar shaft coupling part 45a connected to the second operating rod, and having a hinge part at one end, a packing support frame fixing part 45b at the other end, and a bar shaft coupling part 45a coupled to the bar shaft 5 at an intermediate part thereof. It consists of three working rods (45).

따라서 제2덮개부(20)의 포장지지틀(21)은 제3작동봉(45)의 포장지지틀 고정부(45b)에 볼트(46)에 의해 먼저 결합한 뒤 경사각이 완전히 조절되면 용접에 의해 견고하게 고정되어지는 것이다. 이때 상기 제3작동봉(45)의 끝단에 천막지지틀 고정부(45b)를 형성하지 않고 직접 포장지지틀(21)을 용접하므로써 결합시키는 방법도 고려할 수 있다.Therefore, the packing support frame 21 of the second cover part 20 is first coupled to the packing support frame fixing part 45b of the third operating rod 45 by bolts 46, and then the welding angle is completely adjusted by welding. It is firmly fixed. At this time, without forming the tent support frame fixing portion 45b at the end of the third operating rod 45, a method of joining by directly welding the packaging support frame 21 may be considered.

위와같이 구성된 본 발명 적재함덮개의 동작 및 작용효과를 설명하면 다음과 같다.Referring to the operation and effect of the present invention loading box cover configured as described above are as follows.

즉 본 발명 적재함덮개는 사용하지 않을 때에는 제1,2덮개부가 화물차 적재함의 측면에 두겹으로 절첩되어 있는 상태가 되며, 적재함에 흙, 모래, 자갈등의 적재물을 싣고 운전석에 설치된 닫음스위치를 on시키게 되면 모터(1)가 구동되면서 회동축(3)이 회전하게 되면 동시에 바(4)는 상승하게 되고, 따라서 바축(5)에 연결된 제3작동봉(45a)도 상승하게 되는데 제2덮개절첩수단(40)이 브라켓트(41)에 고정되어 있으므로 제3작동봉(45)의 각이 차이가 나기 시작해 상기 제3작동봉이 바축(5)에 결합된 바축결합부(45a)를 중심으로 회전하게 된다. 따라서 상기 제3작동봉 상단에 고정된 포장지지틀(21)은 제4도에 도시한 것과 같은 순서로 펼쳐지면서 적재함을 덮개되는 것이다.In other words, the present invention when the loading box cover is not in use, the first and second cover parts are folded in two layers on the side of the truck loading box, and loads loads such as soil, sand, and gravel into the loading box and turns on the closing switch installed in the driver's seat. When the rotating shaft 3 is rotated while the motor 1 is driven, the bar 4 is raised at the same time, and thus the third operating rod 45a connected to the bar shaft 5 is also raised. Since the 40 is fixed to the bracket 41, the angle of the third operating rod 45 begins to be different, and the third operating rod rotates about the bar shaft coupling part 45a coupled to the bar shaft 5. . Therefore, the packing support frame 21 fixed to the upper end of the third operating rod is to cover the loading box while being unfolded in the same order as shown in FIG.

절첩시에는 모터의 방향이 반대가 되어 상기의 순서와 반대로 제2덮개부가 절첩되며 이때 스프링(2)은 제2덮개부의 절첩을 용이하게 하는 역할을 하는 것이다.At the time of folding, the direction of the motor is reversed and the second cover part is folded in the reverse order, and the spring 2 serves to facilitate folding of the second cover part.

이와 같은 본 발명 적재함덮개는 한쪽덮개의 너비가 아무리 크게해도 0.7m 정도에 불과하고, 제2덮개주는 안쪽으로 펼쳐지면서 적재함을 덮는 구조이므로 작동시 회전반경이 적어 안전사고의 우려가 적고, 주변 장애물의 영향을 적게 받을 뿐만 아니라 공기의 저항 및 소음의 감소, 사각지대가 현저히 줄어들게 되는 효과를 갖는다.The present invention box cover is only about 0.7m, even if the width of one cover is large, and the second cover is a structure that covers the loading box while expanding inwards, so the rotation radius is small during operation, there is little risk of safety accidents, peripheral obstacles In addition to being less affected by the air resistance and noise reduction, blind spots have the effect of significantly reduced.

또한 덮개의 회전반경이 적으므로 회동축에 걸리는 하중도 적고, 따라서 종래의 모터보다 적은 용량의 모터를 사용할 수 있으므로 경제적이며, 또 본 발명 덮개는 회동축을 종래의 덮개와는 달리 적재함 측면에 회동축을 설치할 수 있으므로 페이로다 또는 포크레인의 화물적재 작업시 버켓에 의한 회동축의 손상을 방지할 수 있으며, 제2덮개부는 어느정도 경사각을 조절할 수 있으므로 적재량이 많게 되면 덮개가 각을 유지하는 상태로 덮어주어 덮개의 중간부가 들리는 현상을 방지할 수 있으며, 역시 경사각이 조절되는 후방덮개부에 의해 후방적재함도 덮개되어 적재물은 날리는 폐단을 최소화할 수 있는 것이다.In addition, since the rotation radius of the cover is small, the load on the rotating shaft is less, and therefore, it is economical because a motor having a smaller capacity than that of the conventional motor can be used. Coaxial can be installed to prevent damage to the rotating shaft caused by the bucket during cargo loading work of payloader or fork lane, and the second cover part can adjust the angle of inclination to some extent. The middle part of the cover can be prevented from being lifted, and the rear load is also covered by the rear cover part of which the inclination angle is adjusted, thereby minimizing the closing edge of the load.
