이러한 바닥부(10)의 제조방법은, 열가소성수지 조성물을 준비하는 단계를 갖는다. 폴리에틸렌, 폴리프로필렌 등의 올레핀 계열의 열가소성수지의 단독으로 이루어진 조성물 또는 다른 물질과의 조합으로 이루어진 조성물을 100 중량부로 정의한다.The method of manufacturing the bottom portion 10 has a step of preparing a thermoplastic resin composition. 100 parts by weight of a composition made of an olefin-based thermoplastic resin such as polyethylene or polypropylene or a combination with other materials is defined.
그리고, 열가소성수지 조성물 100 중량부를 기준으로 목분재료 60 내지 160 중량부를 준비하는 단계를 갖는다. 목분재료에 함유된 습도는 원료 및 제품의 표면 형성에 악영향을 주고 공극을 초래하기 때문에 목분재료를 미리 건조시킨다. 목분재료 건조시, 높은 온도에 장시간 노출할 경우에는 휘발성 물질의 방출과 변색과 냄새 및 목질성분의 열화를 일으키기 때문에 가능하면 건조온도는 200℃보다 낮아야 한다.And, based on 100 parts by weight of the thermoplastic resin composition has a step of preparing 60 to 160 parts by weight of wood flour material. The humidity contained in the wood flour material pre-drys the wood flour material because it adversely affects the formation of the surface of the raw material and the product and causes voids. When drying wood flour, prolonged exposure to high temperatures causes volatile release, discoloration, odor and deterioration of wood components. Therefore, drying temperature should be lower than 200 ℃ if possible.

도 1과 도 2에 도시된 바와 같이, 커튼부(100)가 펼쳐져서 적재공간(18)의 측면을 막고 있는 경우, 커튼지지부(120)가 커튼부(100)의 내측을 지지하므로 커튼부(100)가 적재공간(18)의 내측으로 밀려들어오는 현상을 방지한다.As shown in FIGS. 1 and 2, when the curtain part 100 is extended to block the side surface of the loading space 18, the curtain support part 120 supports the inside of the curtain part 100 so that the curtain part ( 100 is prevented from being pushed into the inside of the loading space (18).
그리고 커튼부(100)의 걸이부(105)가 바닥부(10)의 하측에 설치된 프레임부(12)에 걸리므로 커튼몸체부(101)가 상하 방향으로 펼쳐진다. 또한 측면걸림부재(106)가 고정걸림편(132)에 걸린 상태에서, 핸들부재(144)를 회전시켜 커튼몸체부(101)를 길이방향(D)으로 당기므로 커튼몸체부(101)가 평평하게 펼쳐진 상태를 유지할 수 있다.Since the hook portion 105 of the curtain portion 100 is caught by the frame portion 12 provided below the bottom portion 10, the curtain body portion 101 is spread in the vertical direction. In addition, in the state in which the side catching member 106 is caught by the fixed catching piece 132, the curtain body 101 is flat because the handle body 144 is rotated to pull the curtain body 101 in the longitudinal direction (D). You can keep it unfolded.
그리고 도 3과 도 4에 도시된 바와 같이, 측면걸림부재(106)가 고정걸림편(132)에서 해제하며, 걸이부(105)의 잠금도 해제된 상태에서 커튼몸체부(101)를 회전지지기둥부(140)가 설치된 방향으로 가압한다. 커튼부(100)의 커튼롤러(104)가 레일부(110)를 따라 이동되므로, 커튼몸체부(101)는 접혀지며 적재공간(18)의 측면이 개방된다.3 and 4, the side locking member 106 is released from the fixed locking piece 132, and the curtain body 101 is rotated while the locking of the hook portion 105 is released. Pressing in the direction in which the pillar portion 140 is installed. Since the curtain roller 104 of the curtain portion 100 is moved along the rail portion 110, the curtain body portion 101 is folded and the side of the loading space 18 is opened.
이때 커튼지지부(120)에 구비된 잠금장치를 해제하고 커튼지지부(120)도 같이 커튼부(100)와 이동되므로 적재공간(18)의 측면을 통한 하역작업이 보다 용이하게 이루어질 수 있다.At this time, since the locking device provided in the curtain support part 120 is released and the curtain support part 120 is also moved with the curtain part 100, the unloading operation through the side of the loading space 18 may be more easily performed.
상술한 바와 같이, 본 발명에 따르면 적재공간(18)의 측면이 막 형상의 커튼부(100)에 의해 개폐되므로 차량의 중량이 감소되어 연료비를 절감할 수 있다. 또한 막 형상으로 이루어진 커튼부(100)는 종래 격판 형상의 측벽부 대비 재료비를 절감할 수 있으므로 생산비를 절약할 수 있다.As described above, according to the present invention, since the side surface of the loading space 18 is opened and closed by the curtain portion 100 having a membrane shape, the weight of the vehicle is reduced, thereby reducing fuel costs. In addition, the curtain portion 100 having a film shape can reduce the production cost compared to the conventional plate-shaped side wall portion.
