JP 2006-117266 A Registered Utility Model No. 3001362

  A container opening which is opened and closed by a door is formed on at least one side surface of the container, and a depth dimension inside the container (an inner distance from an inner surface of the door to an inner surface of the opening facing wall) is defined when the door is closed. Is done. For this reason, the depth dimension of the pallets that can be loaded on the container is naturally limited to the depth dimension inside the container, and even if the total depth dimension of the load loaded on the pallet is less than the depth dimension inside the container, If the dimension is longer than the depth dimension inside the container, such a pallet (large pallet) cannot be loaded on the container.

  In addition, since a large pallet can be loaded, the depth of the inside of the container can be increased by reducing the thickness of the door.However, in order to secure the rigidity of the container, the thickness of the door is limited. It is difficult to balance loading and securing the rigidity of the container.

  Contrary to the case of a large pallet, when loading a pallet (small pallet) with a depth dimension shorter than the depth dimension inside the container and a large difference in the dimension, the pallet in the depth direction inside the container is loaded. A structure for regulating movement is required.

  As described above, in the conventional container, it is difficult to flexibly cope with the difference in the depth dimension of the pallets to be loaded while securing the rigidity of the container.

  The present invention has been made in view of the above circumstances, and has as its object to provide a container that can flexibly cope with a difference in the depth dimension of a pallet to be loaded while securing rigidity of the container.

  In order to achieve the above object, a first aspect of the present invention provides a container opening having a predetermined opening height and opening width provided on one side surface of a rectangular box-shaped container main body that partitions a container accommodating chamber inside. The container is configured such that the container storage chamber is opened to the outside of the container by the container opening, and includes a door and a collapsible member.

  The door is provided in correspondence with the opening main area excluding a strip-shaped opening lower edge area extending along the opening width direction from the lower end edge of the container opening to the predetermined height in the entire area of the container opening. The container body is movably supported between a closed position for closing and an open position for opening the opening main area. The collapsible member is provided corresponding to the lower edge region of the opening in the entire area of the container opening, and stands up along the width direction of the opening to close the lower edge region of the opening. The container is supported on the container body side so as to be tiltable between a falling position where the lower edge region is opened.

  The container body partitions the lower part of the container storage room, and has a container floor on which a pallet carried into the container storage room through the container opening is placed. The inner surface of the retractable member in the upright position has a pallet facing surface area facing the opening side end of the pallet placed on the container floor from outside the container.

  When loading and transporting the pallet loaded with the load in the container together with the load, the door is moved from the closed position to the open position, the retractable member is moved down from the standing position to the down position, and the entire area of the container opening is opened, After the pallet is carried into the container storage room through the container opening and is placed at a predetermined position on the container floor, the foldable member is tilted to the upright position, and the door is moved to the closed position. And it is closed by the collapsible member.

  In the above configuration, the door at the open position is opened by setting the upper end edge of the retractable member in the upright position at a height position equal to or higher than the upper surface (upper end of the opening side end) of the pallet placed on the container floor. In addition, at a height position higher than the upper surface of the pallet placed on the container floor, the pallet can be moved to the closed position without interfering with the pallet. Thereby, the thickness of the door can be arbitrarily set without being affected by the depth dimension of the pallet (horizontal dimension orthogonal to the container opening) so that the rigidity of the container is sufficiently ensured.

  Further, by setting the thickness of the foldable member (the position of the pallet facing surface area) according to the depth dimension of the pallet (the position of the opening side end of the pallet placed on the container floor) (for example, the The depth of the container body according to the depth dimension of the pallet to be mounted, etc.), the depth dimension of the container storage chamber (the inner dimension distance from the inner surface of the door at the closed position to the inner surface of the opening facing wall of the container body) It is possible to use a pallet having a longer depth dimension (large pallet), and to prevent the pallet from moving in the depth direction by the collapsible member at the upright position and the opening facing wall of the container body. Can be flexibly coped with a difference in the depth dimension of the pallet without changing the structure of the pallet.

  A second aspect of the present invention is the container according to the first aspect, wherein the pallet-facing surface area of the retractable member in the upright position is disposed outside the container than the inner surface of the door in the closed position.

  In the above configuration, even when using a large pallet having a depth dimension longer than the depth dimension of the container storage chamber, the depth dimension of the entire package loaded on the pallet is equal to or less than the depth dimension of the container storage chamber, and If the depth of the pallet is smaller than the depth of the lower part of the container storage chamber (the inner distance between the pallet-facing surface area of the retractable member in the upright position and the opening-facing wall of the container body), the load is loaded. The entire area of the container opening can be closed by the door and the collapsible member in a state where the pallets thus set are accommodated in the container accommodating chamber and loaded at a predetermined position on the container floor. Therefore, a large pallet can be used without changing (increasing) the outer dimensions of the container.

  A third aspect of the present invention is the container according to the first or second aspect, wherein the collapsible member includes an inner surface of the collapsible member in the upright position and an opening-side end of a pallet placed on the container floor. An elastic cushioning material interposed between the first and second parts is fixed.

  In the above configuration, since the elastic cushioning material is interposed between the inner surface of the retractable member in the upright position and the opening end surface of the pallet placed on the container floor, it is possible to prevent damage to the opening end of the pallet. The pallet can be prevented from moving in the depth direction.

  A fourth aspect of the present invention is the container according to any one of the first to third aspects, wherein a lashing rail for hanging a lashing belt is fixed to the collapsible member.

  In the above configuration, the movement of the load in the container storage chamber can be restricted by the lashing belt.

  According to the present invention, it is possible to flexibly cope with a difference in the depth dimension of a pallet loaded on a container while securing the rigidity of the container.

A rubber gasket 50 is provided on the peripheral edges of the left and right doors 3 to close the gap between the door 3 and the container frame 15 and the gap between the door 3 and the lower plate 4 in the fully closed state to secure the water tightness of the container storage chamber 6. (See FIGS. 3 and 8).

  The door lock mechanism 23 has a lock rod 24, upper and lower cams 25, and upper and lower cam keeper 26. The lock rod 24 extends in a substantially vertical direction along each outer surface of the left and right doors 3, and is rotatably supported on the outer surface of the door 3 by a rod bracket 27 on the outer surface of the door 3. In the present embodiment, four lock rods 24 (two for each of the left and right doors 3) are provided. The upper and lower cams 25 are respectively fixed to the upper end and the lower end of each lock rod 24 and rotate integrally with the lock rod 24. The upper cam keeper 26 is fixed to the front outer surface of the opening upper frame 17, and the lower cam keeper 26 is fixed to the outer surface of the lower plate 4. The upper cam 25 and the lower cam 25 have the same structure, and the upper cam keeper 26 and the lower cam keeper 26 have the same structure. When the door 3 is moved from the open position to the closed position with the lower plate 4 locked in the upright position by the plate lock mechanism 33, the upper and lower cams 25 engage with the upper and lower cam keeper 26, respectively, and the lock rod 24 is The door 3 is rotated in the lock direction 61 to lock the door (see FIG. 7A), and the door 3 is held at the closed position. In the door locked state, the door 3 is opened by rotating the lock rod 24 in the unlocking direction (counter-door locking direction) 62, so that the door 3 is opened and the upper and lower cams 25 and the upper and lower cam keeper 26 are moved.

The door handle 28 is rotatably supported by the lock rod 24 so as to tilt vertically in a plane including the axis of the lock rod 24, and extends in a direction crossing the axis of the lock rod 24. The lock rod 24 rotates in a door lock direction 61 (see FIG. 7) by pushing the door handle 28 toward the door 3, and unlocks in a lock release direction 62 (FIG. 7) by pulling the door handle 28 away from the door 3. See). A handle catch (not shown) is fixed to the outer surface of the door 3 so that the door handle 28 can be inserted and locked from above with the lock rod 24 sufficiently rotated in the door locking direction 61. The door 3 is moved to the closed position, the upper and lower cams 25 engage the upper and lower cam keeper 26, respectively, and the door handle 28 is locked to the handle catch, whereby the rotation of the lock rod 24 is restricted, and the cam 25 and the cam keeper 26 is prevented from being disengaged, and the door 3 is held at the closed position. When the door 3 is to be opened, the door handle 28 is lifted off the handle catch, and then the door handle 28 is pulled to rotate the lock rod 24 in the unlocking direction 62.

  Next, the lower plate 4, the lower hinge 31, and the plate lock mechanism 33 will be described in detail.

  As shown in FIGS. 3, 4 and 8, the lower plate 4 is formed by bending a metal plate, and is fixed to both ends of the lower plate main body 34 to be upward. It has a pair of left and right extension plates 35 extending in the form of a flat metal plate.

  As shown in FIGS. 3 and 4, the lower plate body 34 is in a fully closed state of the container opening 5 (a state in which the lower plate 4 is locked in the upright position and the left and right doors 3 are locked in the closed positions). One end surface portion 36 facing the lower end surface of the door 3 from below, an end surface portion 37 that bends substantially vertically downward from an inner edge inside the container of the one end portion 36, and an outer edge outside the container of the one end portion 36 A first wall surface portion 38 which is bent substantially vertically downward, a step surface portion 39 which is bent outward from the lower end edge of the first wall surface portion 38 and extends substantially horizontally, and an outer edge of the step surface portion 39 outside the container. An opening lower edge region integrally including a second wall surface portion 40 which is bent substantially vertically downward and extends and a second end surface portion 41 which is bent from the lower end edge of the second wall surface portion 40 to the inside of the container and extends substantially horizontally; In the opening width direction over almost the entire area of 5B Standing I.

  As shown in FIG. 6, each of the four lower hinges 31 includes a pair of left and right hinge movable plates 42 fixed to the lower plate body 34 and a pair of left and right hinge fixing plates fixed to the outer surface of the lower opening frame 16. 43 and a hinge shaft 32 extending substantially horizontally along the opening width direction. The hinge movable plate 42 and the hinge fixing plate 43 are each a metal flat plate substantially orthogonal to the opening width direction, and the hinge movable plate 42 is fixed to the other end surface portion 41 of the lower plate main body 34 and has a second wall surface portion. It extends in a direction away from 40. The left and right hinge fixing plates 43 are disposed between the left and right hinge movable plates 42, and the hinge shaft 32 penetrates the left and right hinge movable plates 42 and the left and right hinge fixing plates 43. Thus, the lower plate 4 is supported so as to be tiltable about a hinge shaft 32 between a standing position (indicated by a two-dot chain line in FIG. 4) and a lying position (indicated by a solid line in FIG. 4).

  As shown in FIGS. 3 and 4, when the container opening 5 is fully closed, the upper edge 8 of the lower plate 4 is defined by one end surface 36 of the lower plate main body 34, and the first wall surface 38 of the lower plate main body 34. Is located on substantially the same plane as the outer surface of the door 3, and the outer surface of the second wall portion 40 is located on substantially the same plane as the outer end of the rod bracket 27. The lower cam keeper 26 is fixed to the outer surface of the first wall portion 38.

  With the pallet 52 stored in the container storage chamber 6 and the lower plate 4 locked in the upright position, the upper edge 8 of the lower plate 4 (one end surface 36 of the lower plate main body 34) is placed on the container floor 7. The upper inner surface of the second wall portion 40 of the lower plate body 34 is set at a height position equal to or higher than the upper surface of the pallet 52 (the upper end of the opening side end portion 53 of the pallet 52). The pallet facing surface area 9 faces from the outside of the container, and the lower inner surface of the second wall portion 40 becomes the frame facing surface area 10 facing the outer surface of the lower opening frame 16 from the outside of the container. The pallet-facing surface area 9 and the frame-facing surface area 10 of the lower plate 4 in the upright position are arranged outside the container than the inner surface of the door 3 in the closed position.

  An elastic cushioning material 54 and an elastic sealing material 55 are fixed to the pallet facing surface area 9 and the frame facing surface area 10 by sticking or the like. The elastic cushioning member 54 is interposed between the pallet facing surface area 9 and the opening end 53 of the pallet 52 in a state where the pallet 52 is accommodated in the container accommodating chamber 6 and the lower plate 4 is locked in the upright position. The elastic sealing material 55 is in close contact with the front outer surface of the lower opening frame 16 with the lower plate 4 locked in the upright position. The elastic sealing material 55 ensures watertightness between the lower plate 4 and the lower opening frame 16 when the container opening 5 is fully closed.

  As shown in FIG. 8, the left and right extension plates 35 fixed to both ends of the lower plate main body 34 overlap the opening side end surfaces 13a of the left and right side walls 13 from the outside of the container in a state where the lower plate 4 is set to the upright position. . Each of the left and right plate lock mechanisms 33 is engaged with the left and right plate lock handles 44 rotatably supported by the extension plate 35 and the opening side end surfaces 13 a of the left and right side walls 13 above the extension plate 35. And a hook 45. The plate lock handle 44 is integrally formed with a locking piece 47 and an operation handle 48 facing each other with the rotation shaft 46 interposed therebetween. The locking piece 47 is a fan-shaped plate in a plan view, and the operation handle 48 is rotated from the plate lock position (shown by a solid line in FIG. 8) extending substantially vertically downward from the rotation shaft 46. It is tiltable between an unlocked position (indicated by a two-dot chain line in FIG. 8) that moves outward in the opening width direction around the shaft 46. At the plate lock position, the locking pieces 47 of the plate lock handle 44 enter and engage with the engagement hooks 45, and the lower plate 4 is held at the upright position. By tilting the plate lock handle 44 from the plate lock position to the unlock position, the locking piece 47 is disengaged from the engagement hook 45, and the lower plate 4 can tilt from the standing position to the falling position. The opening horizontal frame 18 is formed with a notch 18c for avoiding interference with the plate lock handle 44 (operation handle 48) which moves to the unlock position.

  When the pallet 52 loaded with the load 51 is loaded together with the load 51 on the container 1 and transported, the left and right doors 3 are moved from the closed position to the open position, and the lower plate 4 is moved down from the standing position to the lying position, and After the opening 5 is fully opened, the pallet 52 is carried into the container accommodating chamber 6 from the container opening 5 and is placed at a predetermined position on the container floor surface 7, and then the lower plate 4 is tilted to the standing position and locked, and The door 3 is moved to the closed position and locked, and the entire area of the container opening 5 is closed by the left and right doors 3 and the lower plate 4.

  In the present embodiment, the upper edge 8 of the lower plate 4 at the upright position is set at a height position equal to or higher than the upper surface (upper end of the opening side end 53) of the pallet 52 placed on the container floor surface 7. The left and right doors 3 at the open position can be moved to the closed position without interfering with the pallet 52 at a position above the upper surface of the pallet 52 on the container floor 7.

  Therefore, the thickness of the door 3 is arbitrarily set without being affected by the depth dimension Lp of the pallet 52 (an outer dimension in a substantially horizontal direction orthogonal to the container opening 5) so that the rigidity of the container 1 is sufficiently ensured. Therefore, it is possible to flexibly cope with the difference in the depth dimension Lp of the pallets 52 loaded on the container 1 while securing the rigidity of the container 1.

  In addition, a large pallet 52 is used in which the depth dimension Lp of the pallet 52 is longer than the depth dimension L1 of the container storage chamber 6 (the internal dimension distance from the inner surface of the door 3 at the closed position to the inner surface of the opening facing wall 14). Even in this case, the depth Lg of the luggage 51 on the pallet 52 is equal to or less than the depth L1 of the container storage room 6 and the depth Lp of the pallet 52 is set to the depth L2 of the lower part of the container storage 6 (standing position). (The inner distance from the pallet-facing surface area 9 of the lower plate 4 to the inner surface of the opening-facing wall 14), the pallet 52 loaded with the luggage 51 is accommodated in the container accommodation room 6 and 7, the entire area of the container opening 5 can be closed by the door 3 and the lower plate 4. Therefore, a large pallet 52 can be used without changing (increasing) the outer dimensions of the container 1.

  For example, in a container that does not include the lower plate 4 and that opens and closes the container opening only by the left and right doors, the pallets that can be used are limited to pallets whose depth Lp is shorter than the depth L1 of the container storage chamber. Therefore, for example, in the case of a container for railway transportation (for cargo) in which the depth dimension L1 of the container storage chamber is 2275 mm, a large pallet 52 having a depth dimension Lp longer than 2275 mm (for example, the depth dimension Lp is about 2438. When a 4 mm pallet for air transport) is put into the container storage chamber, the left and right doors interfere with the pallet 52 and the container opening cannot be closed.

  On the other hand, in the present embodiment, the upper edge 8 of the lower plate 4 at the upright position is set at a height position higher than the upper surface of the pallet 52 placed on the container floor surface 7, and the lower plate 4 at the upright position is set. Since the pallet facing surface area 9 is arranged outside the container from the inner surface of the door 3 at the closed position, even when the pallet 52 for air transport is used for the container 1 for rail transport, the pallet 52 is not used. The container opening 5 can be completely closed by being housed in the container housing room 6.

  Further, since the elastic cushioning member 54 is interposed between the inner surface of the lower plate 4 at the upright position and the opening side end 53 of the pallet 52 placed on the container floor 7, the opening side end 53 of the pallet 52 It is possible to prevent the pallet 52 from moving in the depth direction while preventing damage.

  Further, the thickness of the lower plate 4 (the position of the pallet facing surface area 9) is set according to the depth Lp of the pallet (for example, the lower plate 4 attached to the container body 2 according to the depth Lp of the pallet to be used). , Etc.), the use of the large pallet 52 having the depth dimension Lp longer than the depth dimension L1 of the container storage chamber 6 as described above, The wall 14 makes it possible to prevent the entire pallet from moving in the depth direction and the like, and can flexibly change the depth dimension Lp of the entire pallet by changing the lower plate 4 without changing the structures of the container body 2 and the door 3. Can be handled.

  For example, when the depth dimension Lp of the entire pallet is shorter than the pallet 52 for air transport (for example, the pallet 56 for general transport (depth dimension: 1100 mm) with respect to the container 1 for rail transport in the depth direction). When two sheets are used side by side (when the overall depth Lp of the pallet is 2200 mm), as shown in FIGS. 9 and 10, the pallet-facing surface area 29 at the upright position protrudes more inside the container than the inner surface of the door 3. The lower plate 70 may be used. In this case, the elastic cushioning member 54 may be fixed to the lower plate 70 (see FIG. 9), and the lashing rail 30 for latching the lashing belt 57 for restricting the movement of the load is elastically cushioned. Instead of or in addition to the material 54, the lower plate 70 may be fixed to the pallet facing surface area 29 (see FIG. 10). The lashing rail 30 is a molded product of a metal plate having a hat-shaped cross-sectional shape. A flat-shaped top portion of the hat-shaped cross-sectional shape has an I-shaped or other long hole-shaped locking hole (not shown). A large number are provided at predetermined intervals in the longitudinal direction (opening width direction) of the lashing rail 30. One end of the lashing belt 57 is hung on the lashing rail 30 by locking the locking fitting 58 provided at one end of the lashing belt 57 into the locking hole of the lashing rail 30. A lashing rail (not shown) to which the other end of the lashing belt 57 is hooked is also fixed to the inner surface of the opening facing wall 14 (see FIG. 5), like the lower plate 70 on the opening side. By hooking one end and the other end of the lashing belt 57 on the lashing rail 30 of the lower plate 70 and the lashing rail of the opening facing wall 14, the lashing belt 57 is stretched in the depth direction in the container accommodating chamber 6, and The lashing belt 57 can restrict the movement of the load (pallet or load) in the left-right direction (the direction crossing the depth direction).
