Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prefabricated transportation container having a latching structure, and more particularly, to a prefabricated container in which a panel of a container and a canopy can be simultaneously connected by one latching structure. It relates to shipping containers.

[0002]

BACKGROUND OF THE INVENTION A number of steel shipping containers have been developed by the present inventors that are easy to assemble by simple operations and therefore easy to disassemble in the reverse procedure. For example, Japanese Utility Model Application No. 61-72761 (Japanese Utility Model Application No. 62-1)
85295), Japanese Utility Model Application No. 61-139751,
3-46329) or Japanese Patent Application No. 2-270449 discloses an example of such a steel transportation container which is easy to assemble and disassemble. One of the features of these shipping containers is that the side walls (panels) are erected on the floor pedestal, and the bottom side edges of the side walls are simply engaged with the grip members provided around the four sides of the floor structure. The box-shaped structure can be easily assembled without using it and can be easily disassembled by the reverse procedure.

Further, Japanese Patent Application No. 2-270449 discloses a metal fitting (70) for connecting the assembled box and lid, which is originally used when the box is disassembled and returned. Since it is for a collection set and is a specially-made bespoke component, it is not suitable for general use because it is expensive, bulky, and noticeable from the outside. Therefore, it is normal to assemble this type of assembled container with a belt etc. after assembling to prevent the inside from being seen and to prevent theft, etc. The work to do is laborious and requires labor, which is not preferable. In addition, in the conventional assembling type container, there is one in which a latch or the like is used to connect two adjacent side walls (panels), but a structure in which a canopy attached to this is also connected at the same time is provided. unknown.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention provides an assembling type container having a locking structure in which a panel and a canopy are simultaneously locked by a simple and inconspicuous structure to prevent theft and the like. It is an object of the present invention to provide an assembling type transport container provided with the assembly type transport container.

[0005]

Therefore, according to the present invention, a pair of side panels having vertical pillar members having U-shaped cross-sections on both left and right sides and an upper gusset member for covering the upper edge of the side plate on the upper side are provided. In an assembling type transport container in which the end panel is assembled in a box shape and the canopy is attached from above, a slidable pin shaft and a pin shaft are provided under the upper gusset material close to the vertical pillar material of the end panel. A hooking member having a guide / lock portion that guides and locks is attached, and a through hole for inserting and removing the pin shaft is formed in the inner wall of the vertical strut member, and the vertical strut member is provided at a corner of the canopy. The present invention provides an assembling type transport container having a hooking structure, characterized in that a hooking receiver extending to the pin shaft passage in the hollow portion is provided. If the lid is rigid, the inside cannot be opened even if the panel and the canopy are hooked at only one corner of the box, but the hooking structure of the present invention is a very simple structure and has a thickness within the panel. Since it is so small that it can be hidden, even if two hook members are provided at each corner of the end panel, a total of four hook members will not interfere with the external appearance, and the canopy will be hooked at the four corners. The lock of the shipping container filled with the contents is complete. Specifically, a lock lock can be applied to the guide lock portion to lock the pin shaft so that the pin shaft does not slide, thereby completely preventing theft.

[0006]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a corner portion of an assembling type transportation container equipped with a latching structure according to the present invention, which is looked up from below, in which a column member and a canopy are partially cut away. The shipping container of the present invention comprises two side panels 10 and 2.
A plurality of end panels 20 are assembled and formed in a box shape on a floor base structure (not shown), and each panel is a side plate 1, preferably a side plate made of corrugated steel plate, and an upper gusset material 2 covering the upper edge thereof.
Lower gusset material 4 fixed to the lower edge (partially shown in FIG. 2)
The side panel 10 has vertical pillar members 11 having U-shaped cross sections on both sides thereof, and the end panel 20 has vertical pillar members 21 sized to embrace the pillar member 11 on both sides. There is. A portion of the side plate 1 close to the vertical support member is processed as a flat portion 3 and a latch (latch) member 40 is attached thereto.

As shown in FIG. 2, the retaining member 40 has its rear surface fixed to the flat portion 3 of the side plate 1 and the side walls 4 from both sides thereof.
1 is extended to the front. A pin shaft 42 is horizontally slidably mounted through a through hole formed in the side wall. The approximately middle portion of the pin shaft 42 is deformed as a curved portion 43, and normally this curved portion 43 hangs vertically downward (state of FIG. 1). Two guide portions 44 that guide the slide of the pin shaft 42 are provided so as to project forward from the back wall of the latch member. If the curved portion 43 of the pin shaft 42 is horizontally taken out and slid as shown in FIG. 2, the pin shaft slides along the upper edge of the guide portion and is guided left and right. The guide portion 44 has a lock hole 45, and if a lock lock 46 is inserted through the lock hole 45 to lock it, the pin shaft 42 can be locked so as not to slide.

A through hole 22 is formed in the inner wall of the vertical column member 21 of the end frame 20 for allowing the pin shaft 42 to move in and out, as can be seen from FIG. This allows the pin shaft to extend into the vertical column member 21 of the end frame that holds the vertical column member 11 of the side frame 10.

The canopy 3 corresponds to the pin shaft 42 of the latch member.
Latch receivers 31 are provided on the inner surfaces of the zero corners, preferably the four corners. The latch receiver 31 shown in FIG. 1 is made of an elastic material and has a lower end bent into an acute hook shape.
Therefore, when the pin shaft is projected into the hollow portion of the vertical column member in the state as shown in FIG. 1 and the canopy 30 is attached, the latch receiver 31 is elastically deformed and gets over the pin shaft, and the hook tip ends as shown in FIG. As shown by the broken line in FIG. In this state, the canopy 30 can no longer be opened unless the pin shaft 42 retracts. For this reason, the lock pin 46 as shown by the broken line in FIG.
It is hooked in the lock hole 45 of the guide / lock portion 44 on the front side of 3. Since the curved portion 43 and the lock lock 46 are actually located under the upper gusset material 2 (not shown in FIG. 2) and do not project to the outside, they do not interfere with the work and may make the appearance significantly strange. Absent.

There are two guide lock portions 44 for each hook member, but the inner guide lock portion 44 (the left side in FIG. 2) retracts the pin shaft 42 and bends it.
When 3 is straddled, it can be locked by the lock lock 46 to prevent accidental protrusion of the pin shaft.

FIG. 3 is a partial end view showing an example of the hook receiver 32 having a different shape with respect to the same pin shaft 42. In this example, a hole 33 is formed in a flat plate for inserting the pin shaft, and it is necessary to retract the pin shaft 42 when closing the canopy. FIG. 4 is a perspective view showing still another hook receiver 35. In this example, the end wall 37 is provided on the box-shaped receiving portion 36 that covers the tip of the pin shaft 42.
It is adapted to be attached to the inner surface of the corner portion of the canopy 30 by 8.

In addition to the hooking members described above and illustrated, for example, instead of the curved portion 43, one horizontal bar is projected in a T-shape in a direction substantially perpendicular to the pin axis, and the horizontal bar is brought close to it. It is also possible to use a locking member that is sandwiched between two guide / lock portions to be locked. In this case, when not in use, 2
By arranging the T-shaped bar inward of the inner part of the guide lock part, it is possible to prevent unintentional protrusion of the pin shaft.

[0013]

As described above, according to the present invention, the panel and the canopy are constituted by the small latching member which can be accommodated within the thickness of the panel having a certain thickness and the latching receiver provided on the inner surface of the canopy. Since they can be joined at the same time, a simple and complete locking of the prefabricated transport container is possible without the need for large-scale special parts. The latching member fits within the thickness of the panel, and the lock that locks it also fits within the thickness, so it does not make the appearance of the assembly-type container strange and also interferes with the handling work. Nor. The locking member is provided with two guide locks for locking the lock at all times, and these locks are located close to each other, so there is no risk of forgetting or losing the lock somewhere.
When the hook member is not used, if the pin shaft is retracted and locked, the pin shaft does not project unintentionally and hinder the work.
