AI Technical Summary

Benefits of technology

The present invention provides a collapsible intermodal container stacker and a collapsible intermodal container with a lower wall hingedly attached to the second side wall and a link member hingedly attached to the lower wall and the first side wall. The stacker includes a stationary structure with a planar face and a side wall securing device for securing the first side wall in use. The carriage is movable relative to the stationary structure and includes a track and a carriage frame with rollers engaged with the track. The carriage frame has one or more locking members for attachment to the container. The lower wall hingedly attaches to the lower end of the second side wall and the link member hingedly attaches to the lower wall and the first side wall such that, when the lower wall pivots towards the second side wall, the link member causes the first and second side walls to move towards each other. The invention provides a solution for securely stacking collapsible intermodal containers in a convenient and efficient way.

Problems solved by technology

In international trade, there is usually a trade imbalance between an exporting country and an importing country.
However, once the intermodal containers arrive at the importing country and the goods are unloaded, the intermodal containers are transported back to the exporting country in an empty state for reuse due to the trade imbalance.
The transportation of empty intermodal containers is highly inefficient and involves significant costs, especially in relation to fuel, handling, and storage.
Also, in domestic logistics activities, similar imbalances and thereby similar disadvantages can occur.

first embodiment

[0115]FIGS. 1 to 12 of the accompanying drawings show a collapsible intermodal container 10. The container 10 comprises a right side wall 12 and a left side wall 14. The side walls 12, 14 oppose each other and are substantially parallel to each other. Each of the side walls 12, 14 is formed from a rectangular corrugated steel panel which is surrounded by a rectangular steel frame. The right side wall 12 is defined by an upper longitudinal end 12a, a lower longitudinal end 12b, a front end 12c and a rear end 12d. The left side wall 14 is defined by an upper longitudinal end 14a, a lower longitudinal end 14b, a front end 14c and a rear end 14d.

[0116]As seen in FIG. 4, the right side wall 12 has a lower flange 12e which is disposed at the lower longitudinal end 12b and extends towards the lower longitudinal end 14b of the left side wall 14. The right side wall 12 further has three stop members 12f that are disposed at the upper longitudinal end 12a and are evenly spaced apart between ...

second embodiment

[0137]FIGS. 13 to 21 of the accompanying drawings show a collapsible intermodal container 10′. Features of the collapsible intermodal container 10′ that are substantially identical or similar to those of the collapsible intermodal container 10 are provided with the same reference numerals.

[0138]The collapsible intermodal container 10′ is substantially identical to the collapsible intermodal container 10. However, as best seen in FIG. 13, the collapsible intermodal container 10′ further comprises four lifting systems 30a, 30b, 30c, 30d for use in configuring the container 10′ to the erected configuration. Each of the lifting systems 30a, 30b, 30c, 30d includes an elongate flexible strap 32 for use in lifting the upper wall 16 into position when configuring the container 10′ to the erected configuration. For this reason, the lifting systems 30a, 30b, 30c, 30d are also referred to herein as strap systems 30a, 30b, 30c, 30d, and one of these strap systems 30a will now be described in gr...

third embodiment

[0145]As can be seen in FIGS. 22 and 23, this third embodiment of a collapsible intermodal container 10″ differs in relation to the closure mechanism for locating and securing the front and rear door assemblies 24, 26 in the closed position when the collapsible intermodal container 10″ is being configured to the erected configuration. In this embodiment, instead of a closure mechanism comprising a flap member 24g hingedly attached to the right upright member 24a of the front door assembly 24, with openings 24h adapted to receive respective protrusions 12g on the front end 12c of the right side wall 12, the closure mechanism comprises two closure levers 24i fixed to the front end 12c of the right side wall 12, spaced apart as upper and lower closure levers 24i. Each closure lever 24i has a handle 24j that is operable to extend a latch arm 24k for engaging a catch 24m that is fixed to the upright member 24a of the front door assembly 24 and aligned with the latch arm 24k. The handle 2...

Abstract

The present invention provides a collapsible intermodal container stacker, comprising: a stationary section and a movable section disposed adjacent the stationary section. The stationary section comprises: a substantially upright planar face part; and a side wall securing device configured to operatively connect to a first side wall of a collapsible intermodal container and to secure the first side wall in use against or with respect to the planar face part. The movable section comprises: a track extending substantially perpendicular to the planar face part; a carriage engaged with and movable along the track, the carriage being configured to attach to a second side wall of the collapsible intermodal container in use; and a lower wall moving device configured to operatively connect to a lower wall of the collapsible intermodal container and to move the lower wall in use such that the lower wall pivots upwards. In use, the pivotal movement of the lower wall causes the second side wall to move towards the first side wall and thereby the carriage to move towards the stationary section. The present invention also provides a stacking system comprising: a collapsible intermodal container stacker according to the present invention; and a collapsible intermodal container comprising: first and second side walls, a lower wall hingedly attached to a lower end of the second side wall; and a link member hingedly attached to the lower wall and a lower end of the first side wall such that, when the lower wall pivots towards the second side wall, the link member causes the first and second side walls to move towards each other.

Description

FIELD[0001]The present invention relates to a collapsible intermodal container stacker and a stacking system.BACKGROUND[0002]Intermodal containers, also known as ISO containers or shipping containers, are used to store a wide range of goods for transportation. In general, an intermodal container is a rectangular steel box with doors on either end to provide access to the interior in which goods are stored. The intermodal container also has a casting on each corner for engagement with twistlocks and / or bridge clamps to lock the intermodal container into place or interlock with other intermodal containers when stacked together.[0003]In international trade, there is usually a trade imbalance between an exporting country and an importing country. Typically, intermodal containers are loaded with goods at the exporting country and then transported to the importing country. However, once the intermodal containers arrive at the importing country and the goods are unloaded, the intermodal co...
