Definitions

  • the present invention relates to containers used in cargo transportation, truck loading boxes, railway freight cars, and container houses.
  • PATENT DOCUMENT 1 Japanese Patent No. 6311850
  • An object of the present invention is to provide a container which has a reduced volume and improved transport efficiency when unladen.
  • a container including: a pair of endwalls (14); a pair of sidewalls (12, 38, 42, 52); a top structure (16) and a bottom structure (18); a sidewall rotating means for folding the sidewalls (12, 38, 42, 52) under the top structure (16) or onto the bottom structure (18); an end frame (20) configured to surround four sides of the endwall (14); an endwall tilting means (28, 56) that enables the end frame (20) standing upright on the bottom structure (18) to be lifted and tilted towards the bottom structure (18), wherein the top structure (16) can be raised and lowered along corner posts (20A) between the upper end of the end frame (20) positioned upright and the floor of the bottom structure (18), and the endwall tilting means (28, 56) allows the endwall to be laid down on the top structure (16) which is put on the floor.
  • a recessed portion (32A) for accommodating an auxiliary post (32) being laid down is provided in the bottom structure (18) under the end frame (20) placed upright, and when the auxiliary post (32) is placed upright the tip end of the auxiliary post (32) extends to a position higher than the endwall (14) placed on top of the top structure (16).
  • a connecting mechanism (26) for connecting containers (10) to each other is provided at the tip end of the auxiliary post (32).
  • the endwall tilting means (28, 56) may include a rotating shaft (28A) provided on the side of the bottom structure (18), and an arm (28) having one end supported by the rotating shaft (28A) and the other end fixed to the lower end of the corner post (20A), and the rotating shaft (28A) is located a predetermined distance (D) inward from the endwall (14) in the longitudinal direction.
  • the endwall tilting means (28, 56) may include an endwall guide (56) provided on the side of the bottom structure (18) with a guide groove (56A) along the vertical direction, and an endwall rotation shaft (14B) having one end engaged with the guide groove (56A) and the other end fixed to the lower end of the corner post (20A).
  • a sidewall engaging portion (56) that engages with the upper or lower end of the sidewall (12, 38, 42, 52) may be provided along the side of the top structure (16) or the bottom structure (18).
  • a sidewall storage section capable of storing the sidewalls (12, 38, 42) may be provided on the underside of the top structure (16), the upper side of the sidewall (12) is pivotally supported on the side of the top structure (16), and the left and right sidewalls (12) are stacked and stored inside the top structure (16).
  • the sidewall (38, 42) may be divided into an even number of panels, one above the other, so that the sidewall (38, 42) can be folded inward, and the left and right sidewalls (38, 42) are folded in parallel to each other.
  • the corner posts may be provided with a locking mechanism (39) for preventing the top structure (16) from falling.
  • a container which has a reduced volume and improved transport efficiency when unladen.
  • FIG. 1 is a perspective view showing the general configuration of a container according to a first embodiment of the present invention.
  • the container 10 of the first embodiment includes a pair of left and right sidewalls 12, a pair of front and rear end walls 14, a top structure 16, and a bottom structure 18.
  • the sidewalls 12 are pivotally supported on the side of the top structure 16 via a hinge or the like (sidewall rotating means) and can be rotated toward the inside of the container.
  • the height of the folded sidewalls 12 is less than the width of the top structure 16, and the sidewalls 12 that are rotated inward into the container can be stored inside a sidewall storage section provided on the bottom side of the top structure 16 from the bottom side.
  • the left and right sidewalls 12 are rotated about axes at different heights relative to the top structure 16 and are stacked alternately and stored within the top structure 16, and are fixed in the top structure 16 by a locking mechanism (not shown).
  • the heights at which the left and right sidewalls 12 are pivotally supported on the sides of the top structure 16 are determined according to the aspect ratio of the container 10, and in order to fold both sidewalls 12 alternately, the pivotal positions of the left and right sides may be set to different heights.
  • ISO standard containers have a width W of 2438 mm and three optional heights H of 2896 mm, 2591 mm, or 2438 mm, so the pivotal heights for the sidewalls 12 are adapted to the selected dimension.
  • the lower edges of the sidewalls 12 can be fixed to the sides of the bottom structure 18 by a locking mechanism (not shown).
  • FIG. 2 is a schematic enlarged view of the top surface portion of the container 10. Note that the front end wall 14 is omitted in FIG. 2 .
  • a pair of forklift pockets 16A into which forks of a forklift are inserted are provided near the center of the top structure 16 in the longitudinal direction, spanning the left and right top side frames.
  • the forklift pockets 16A are used when raising and lowering the top structure 16, which stores the sidewalls 12.
  • the elevation of the top structure 16 is performed by the power of a forklift.
  • FIG. 3 is a side view showing how the top structure 16 is lowered.
  • FIG. 4 is a diagram showing how the end wall 14 is pushed down onto the top structure 16 lowered onto the bottom structure 18.
  • FIG. 4(a) shows a state in which the top structure 16 is lowered onto the floor while the front and rear end walls 14 are standing upright on the bottom structure 18.
