Description

  The present invention relates to a container reinforcing member suitable for being attached to a pair of through-holes into which forklift forks are inserted, and a container attached with the same.

  Conventionally, when transporting large-sized fish such as cultured tuna by cooling, the fish is transported to a destination while being cooled in order to keep the fish fresh. In carrying work, a fork of a forklift may be used, and a reinforcing member may be attached to the bottom of the container (for example, see Patent Document 1).

  Moreover, the container 30 shown in FIG. 8 may be used for the container mentioned above. The container 30 is a heat-insulating container in which a heat-insulating material such as foamed polyurethane is injected into a hollow molded product produced by rotational molding of PE resin. At the time of cooling, water ice is put in the accommodating part 31 of the container 30, and a large fish is directly immersed in ice water.

  The container 30 is provided with a drainage mechanism 39 composed of a drainage hole such as a drain outlet and a plug body screwed to the drainage port. The water contained in is drained.

  Here, as a method for draining water from the accommodating portion 31 more quickly and easily, the container 30 is turned over with the one side (fork F2 side) of the insertion holes 38 and 38 into which the forks F1 and F2 of the forklift are inserted as fulcrums. There is a case of draining (see arrow in FIG. 8). The container 30 is also used as an ice storage container, and such work is also performed when transferring the ice from the container 30 to another container. However, there is a case where ice becomes an ice block and adheres to the wall surface of the container 30 of the container 30. In this case, the container 30 is vibrated in the vertical direction with the container rotated 90 degrees (standing up). There is work.

Japanese Patent No. 4190719

  However, when the above-described container is used, the container 30 is rotated 90 ° with the insertion hole 38 of the forks F1 and F2 as a fulcrum, and this is raised, so that the bottom side corner of the insertion hole 38 (part A in FIG. 8) In addition to the concentrated load acting, the ice block may be detached from the wall surface due to the above-described vertical vibration, and an impact may be applied. Thereby, the container 30 may be damaged from the bottom side corner of the insertion hole 38.

  In addition, since the container as described in Patent Document 1 does not assume such a draining operation and an ice transferring operation, the fork insertion hole is not formed in a part of the container and is attached. It consists only of reinforcing members. Therefore, it cannot be said that the reinforcing member described above has sufficient strength to withstand the concentrated load when the container stands.

  Therefore, in the container 30 shown in FIG. 8, it is only necessary to increase the thickness of the bottom side corner of the insertion hole 38, but it is not easy from the viewpoint of formability to increase the thickness of only this portion. In particular, when the container 30 is manufactured by the rotational molding described above, it is not easy to increase the thickness of this portion (the resin thickness of the skin of the hollow molded product).

  That is, if the thickness of this portion is increased, the resin thickness of the entire skin of the hollow molded article increases, thereby reducing the thickness of the heat insulating material and lowering the heat insulating property of the container. In addition, the weight of the container increases and the transportation cost also increases.

  The present invention has been made in view of the above points, and the object of the present invention is to insert a fork of a forklift into a pair of insertion holes when draining water or transferring ice, and to raise the container. Even if the container is vibrated in this state, it is an object of the present invention to provide a container reinforcing member capable of preventing the bottom corner of the insertion hole from being damaged and a container attached with the same.

  In order to solve the above-mentioned problem, a container reinforcing member according to the present invention is a container reinforcing member formed on a bottom side wall of a container and attached to a pair of insertion holes into which a fork of a forklift is inserted, The container reinforcing member is formed to fit along a lower wall surface of the insertion hole and an opposing inner wall surface continuous with the lower wall surface.

  According to the present invention, the container reinforcing member is formed to fit along the lower wall surface of the insertion hole and the opposing inner wall surface continuous with the lower wall surface. The mechanical strength of the bottom side corner can be increased. Thereby, even if the fork of the forklift is inserted into the pair of insertion holes and the container is raised, the bottom corner of the insertion hole can be prevented from being damaged. Moreover, the shape mentioned above also enables the container reinforcing member to be easily attached to and detached from the insertion hole.

  Furthermore, as a more preferable aspect, the container reinforcing member has a bent portion that is bent from the opening of the insertion hole along the bottom side wall. According to this aspect, the periphery of the opening of the insertion hole can be protected by the bent portion. Thereby, when the fork is inserted into the insertion hole, the container can be prevented from being damaged due to contact of the tip of the fork around the opening.

  Further, as a preferred aspect, a pair of edge legs projecting so as to support the container are formed at the bottom of the container along the opposing edge of the container, and the pair of insertion holes The container reinforcing member is fastened together with the bent portion and a clamping member for clamping the edge leg from the inside of the edge leg. ing.

  According to this aspect, the bent portion is arranged outside the edge leg portion which is the bottom side wall of the container, the clamping member is arranged inside the edge leg portion, and the edge leg of the container is formed by the bent portion and the clamping member. Since the portion is sandwiched, the container reinforcing member can be prevented from falling off from the container.

  According to the present invention, even when the forklift fork is inserted into the pair of insertion holes when the water is drained or the ice is transferred and the container is raised, and the container is vibrated in this state, the bottom corner of the insertion hole is Breakage can be prevented.

  As shown in FIGS. 1 to 3, the container 30 according to the present embodiment is a container for transporting the stored items such as large fish such as cultured tuna in a cold state. The container 30 is a heat-insulating container in which a heat-insulating material 30B such as foamed polyurethane is injected into a hollow molded product 30A produced by rotational molding using a polymer resin such as PE resin (for example, (See FIG. 5).

  Here, the container 30 is formed with a storage portion 31 for storing water ice, ice, and the like together with the storage product, and a collar portion 32 is formed in the opening 30 a of the storage portion 31. Suspension holes 33 are formed at the four corners of the container 30 in which the flange 32 is formed.

  A pair of insertion grooves 35 and 35 into which a fork of a forklift is inserted are formed at the bottom of the short side wall 30d of the container 30. By forming the insertion grooves 35, 35, a pair of edge legs 37, 37 projecting so as to support the container 30 are formed on the bottom 30 b of the container 30 along the opposing edges of the container 30. Further, a central leg portion 36 is formed between the edge leg portions 37 and 37.

  A pair of insertion holes 38 and 38 into which a fork of a forklift is inserted are formed in the bottom (bottom side wall) 30b constituting the longitudinal side wall 30c of the container 30. The pair of insertion holes 38 are formed so as to penetrate the edge leg portions 37 and the center leg portion 36.

  In this embodiment, the container reinforcing members 10 and 10 for reinforcement are attached to the pair of insertion holes 38 and 38 formed in the respective edge leg portions 37. The container reinforcing member 10 is formed, for example, by press sheet metal working of a galvanized steel sheet having a thickness of 2 to 3 mm.

  As shown in FIGS. 3 and 4, the container reinforcing member 10 is formed along the bottom plate portion 13 formed along the lower wall surface 38c of the insertion hole 38 and the inner wall surface 38b facing the lower wall surface 38c. It has a pair of side plate parts 12 and 12 formed. The bottom plate portion 13 and the pair of side plate portions 12 and 12 are fitted to the inner wall surface 38b facing each other. With such a shape, the container reinforcing member 10 can be easily attached to the insertion hole 38 from the insertion direction S and can be easily removed from the opposite direction side.

  For example, the container reinforcing member 10 can be fitted into the insertion hole 38 by slightly increasing the distance between the outer surfaces of the side plate portions 12 and 12 with respect to the distance between the pair of inner wall surfaces 38b and 38b. . Further, in order to facilitate the insertion of the container reinforcing member 10 into the insertion hole 38 from the insertion direction S shown in FIGS. 1 and 2 while satisfying such a fitting relationship, the side plate portions 12, It is preferable to reduce the distance between the 12 outer surfaces. Further, the distance between the inner wall surfaces 38b, 38b may be narrowed as the insertion hole 38 itself advances in the insertion direction S. In this case, the container reinforcing member 10 can be suitably fitted into the insertion hole 38 by changing the inclination angle of the side plate portion 12 with respect to the inclination angle of the inner wall surface 38b.

  The side plate portions 12 and 12 and the bottom plate portion 13 are continuously formed via an R portion (for example, about R20) that is 1/5 to 1/3 of the height of the insertion hole 38. The concentrated load from the fork acting on the corner of the reinforcing member 10 can be dispersed.

  Further, the container reinforcing member 10 has a bent portion 14 that is bent from the outer opening 38 a of the insertion hole 38 along the bottom side wall 30 b, and the bent portion 14 is formed continuously with the bottom plate portion 13. Has been. The container reinforcing member 10 has such a length as to protrude inward from the inner opening 38 d of the edge leg portion 37. A pair of elongated holes 15 for fastening the clamping member 20 with the root bolts 40 are formed at positions inside the edge leg portions 37 of the container reinforcing member 10.

A square hole 25 is formed in the fastening plate portion 22 at a position that coincides with the long hole 15 of the container reinforcing member 10. Each square hole 25, 25 can be inserted with a square columnar corner 42 of the root bolt 40, and has such a size that the root bolt 40 is locked when fastened.

  When attaching the container reinforcing member 10 to the container 30, first, the bent portion 14 is brought into contact with the bottom side wall 30 b, and the long hole 15 of the container reinforcing member 10 and the square hole 25 of the fastening plate portion 22 are formed. The clamping plate portion 23 of the clamping member 20 is brought into contact with the edge leg portion 37 so as to match.

  Next, in this contact state, the root bolt 40 is inserted into the long hole 15 and the square hole 25, and the corner portion 42 is locked to the long hole 15 and the square hole 25. Next, the root bolts 40 locked to the square holes 25 are slid along the long holes 15 together with the holding members 20, and the holding plate portions 23 are brought into contact with the edge leg portions 37. While maintaining this contact state, the nut 46 is screwed together with a locking washer (not shown) from the threaded portion 43 side of the root bolt 40, and the nut 46 is tightened. Thus, the root bolt 40 with the corner 42 engaged with the long hole 15 and the square hole 25 does not rotate, and the container reinforcing member 10 includes the bent portion 14 and the inner side of the edge leg 37. Therefore, the clamping member 20 that clamps the edge leg portion 37 is fastened.
