Joint structure for portable work and storage container

Abstract

A joint structure for portable work and storage container includes a plurality of joint members and a plurality of reinforcing shafts. Each joint member includes an upper joint extended from a top retention frame, a lower joint extended from a bottom retention frame, and a shaft holder alignedly mounting between the upper and lower joints to form a reinforcement channel. The reinforcing shafts are disposed within the reinforcement channels and coupling between the upper and lower joints through the shaft holders respectively, wherein each of the reinforcing shafts has an upper portion received in a respective upper socket of the upper joint, a lower portion received in a respective lower socket of the lower joint, and a mid-portion received within the respective shaft holder such that the joint structure reinforces the a strength between the top and bottom retention frames to rigidly support the wall frame.

Description

BACKGROUND OF THE PRESENT INVENTION[0001]1. Field of Invention[0002]The present invention relates to a portable work and storage container, and more particularly to the joint structure for the portable work and storage container, wherein the joint structure not only enhances the rigid structure of the portable work and storage container but also allows the portable work and storage container to be disassemble for storage and transportation.[0003]2. Description of Related Arts[0004]A storage container, such as a cargo, is considered as one of common tools for transporting a load over land, sea, or through the air. A conventional storage container comprises four sidewalls, a top wall, a bottom wall, and a frame structure supporting the walls to form a rectangular shaped container. Since the load is relatively heavy, generally more than thousands pounds, the storage container must be transported by lifting machine from one spot to another spot. Thus, the frame structure must be rigid e...

AI Technical Summary

Benefits of technology

[0008]A main object of the present invention is to provide a joint structure for a portable work and storage container, wherein the joint structure not only enhances the rigid structure of the portable work and storage container but also allows the portable work and storage container to be disassemble for storage and transportation.

[0010]Another object of the present invention is to provide a joint structure for a portable work and storage container, wherein the upper and lower joints are detachably coupling with the reinforcement shafts such that the portable work and storage container can be set up to provide a rigid structural configuration and can be collapsed into an impact size.

[0011]Another object of the present invention is to provide a joint structure for a portable work and storage container, wherein the storage container is easy to assemble and disassemble without weakening the strength of the joint structure.

[0013]Another object of the present invention is to provide a joint structure for a portable work and storage container, which does not require to alter the original structural design of the storage container, so as to minimize the manufacturing cost of the storage container incorporating with the existing lifting machine.

[0014]Another object of the present invention is to provide a joint structure for a portable work and storage container, wherein no expensive or complicated structure is required to employ in the present invention in order to achieve the above mentioned objects. Therefore, the present invention successfully provides an economic and efficient solution for providing a rigid configuration for the storage container and for enhancing the transportation ability when the storage container is folded into an impact size.

Problems solved by technology

In addition, the storage container requires lots of space for storage or transportation even though the storage container is empty.

In other words, the storage container cannot be disassembled for storage and transportation purposes.

Therefore, when the storage container is empty, the mover can only carry one storage container at one time to transport the storage container from one place to another place.

However, the joint, especially for the movable joint parts thereof, will substantially weaken the overall structure of the frame structure because the stress will be created around the joint.

Therefore, it is a conflict between the strength enhancement of the storage container and the collapsible feature of the storage container for easily transportation.

The existing storage container obviously cannot achieve the current needs of the users to provide both strength enhancement and collapsible feature for the storage container.
