Description

[Detailed Description of the Invention] A. Purpose of the Invention [Field of Industrial Application] The present invention relates to a device for firmly joining upper and lower containers when stacking containers.

[Conventional technology]

This type of conventional joining device has a hollow fixing leg provided on the lower surface of the corner of the container, and the lower end of the corner post of the stacked upper container and the upper end of the corner post of the lower stacked container are inserted into the hollow fixing leg. A device with a mechanism to prevent it from coming off (Jikko 54-)
(see Publication No. 36931), or by overlapping the lubricant on the bottom of each side of the lower frame of the upper container and the lumber fixedly provided on each side of the upper frame of the lower container, and joining the two with hook bolts (actual). (see Publication No. 1983-24191), etc. are known.

[Problem that the invention attempts to solve]

As in the former example above, it is difficult to align and insert the lower ends of several pillars at each corner of the upper container into several hollow fixed leg holes at each corner of the lower container at the same time. Since the fittings have to be shifted and fitted together, the work is troublesome and the insertion portion is easily damaged, which is particularly a problem in the case of heavy containers.

Moreover, the latter has a complicated structure and is expensive.

The present invention provides a stacked container joining device that solves the above problems.

B. Structure of the invention [Means for solving the problem] The invention provides a joint fitting 7 having two outer right-angled surfaces 7a and 7b as inclined _surfaces .
4. An inward right-angled joining fitting 8, which is provided on the upper surface of the corner where ₂ intersect and engages with the outside of the two right-angled surfaces 7a and 7b, is provided on the lower surface of the corner where the lower frame members 1 and 2 of the container intersect. , a stacked container configured such that containers A and B are stacked by fitting the above-mentioned joint fittings 7 and 8 inside and outside, and are connected with nuts 10 by passing bolts 9 through holes 7c and 8c provided in both fittings. This is a joining device.

[Effect]

When loading the upper container with a forklift or the like, even if the containers are misaligned front to back, left or right, the two outward facing right-angled surfaces 7a and 7b of the upper joint fitting 7 will guide the corresponding sides of the lower inward right-angled joining fitting 8. However, since this action is performed between the upper and lower joint fittings 7 and 8 at the four corners,
Both metal fittings 7 and 8 fit together easily. The bolt 9 is inserted from the elongated hole 8c of the fitted fitting 8 into the hole 7c of the same 7.
Pass through and connect with nut 10.

〔Example〕

The embodiment shown in the drawings will be described. Since the overall configuration of the container is arbitrary, the drawing shows only the frame members 1 and 2 of the platform frame at one corner, the pillar 3 rising from the corner of both members, and the sliding member 5 on the underside of frame member 1. Only the lower corner (Fig. 2A), the frame members 4 ₁ and 4 ₂ of the ceiling frame at the upper end of the pillar 3, the filler plate, and the diagonal members (Fig. 1) are shown, and other auxiliary members or enclosure members are shown. etc. will be omitted.

The frame members 1 and 2 of the upper container are connected through the sliding material 5,
When stacked on the frame members 4 ₁ and 4 ₂ of the lower container, a fork insertion space of a forklift is formed between the left and right sliding members 5 and 5.

In the present invention, joint fittings 7 and 8 are provided on the upper and lower surfaces of the corners of the container, respectively.The embodiment shown in FIG. The arc of the outer circumferential surface of the tube located on the outside of is used as the inclined surface 7b, and the tube hole is connected to the bolt hole 7c.
The joint fitting 7 is constructed by using the two outer surfaces 7a and 7b as inclined surfaces, and is welded and fixed to the corners of the frame members 4 ₁ and 4 ₂ .

The joining fitting 7 shown in Fig. 2B is an L-shaped fitting that is attached with its opening side facing the outside of the container, and the sides of its two right-angled surfaces 7a and 7b are formed into arc shapes or slopes. This is an embodiment in which a bolt hole 7b is provided.

The lower joining fitting 8 is an angled right-angled member that fits outside the upper joining fitting 7. However, in the illustrated container framework, as shown in FIG. 2, joint members 8 are attached along the two outer sides of the pillars 3, and their lower ends are aligned with the lower surfaces of the slip members 5. In this case, the upper joint fitting 7 is mounted so as to be positioned inward by the thickness d of the pillar 3. At that time, the contact surface against the upper joint fitting 7 is the metal fitting 8.
one surface 8a, and the inner surface 5a of the lower sliding member 5, which is perpendicular to that surface.

Please note that there is a slight space S between both metal fittings 7 and 8.
It is better to form it as shown.

C. Effect of the invention Because of the above configuration, when stacking containers as described in the section of the operation, upper containers are guided while guiding the upper and lower frame members 1 and 2 approximately parallel to 4 ₁ and 4 ₂ . When lowered, the upper and lower joint fittings 7 and 8
Even if there is a certain degree of misalignment in the fitting, the two right-angled surfaces 7a and 7b of the metal fitting 7 will guide the two right-angled surfaces of the joining metal fitting 8 in the fitting direction, so that they will fit together easily and smoothly. The work can be carried out more quickly than when a pin such as a narrow diameter portion at the end of a support is fitted into a hole. Furthermore, since the joining fittings can be constructed to be large and sturdy, there is no risk of wear and tear even if they rub or come into contact with each other a little. Corresponding holes 7c and 8 of the fitted joint fittings 7 and 8
Since the bolt 9 is passed through c and tightened with the nut 10, it is easy to integrally connect them, and the construction work is simpler than the conventional hook bolt connection structure.
