PROTECTIVE SEIIELD FOR CONTA~ER
FIELD OF TlEIE INVENTION
The present invention relates to a container, more specifically to freight container, and rnore 10 specifically to one or more protective shields applied to the container doors to prevent mechanical damage during transport.
BACKGROUND OF TEIE INVENTION
Con~ainers, such as freight containers are widely used for shipping goods by road, rail, air and sea.
These structures are typically large rectangular structures specially designed to be handled and stored in the holds of ships, and on railway flat cars, etc.
2 o These cargo containers are typically closeable by pivoted doors, said doors being held in a closed position by lockrods extending vertically over the doors and into cooperating receptors fixed on the surrounding door frame. Said pivoted doors are capable of pivoting due to a hinging means, typically standard hinges. Moreover, lock arms are attached to such lockrods to pivot them about their longitudinal axis for release from the receptors, whereby the pivoted doors may be opened.
2 5 To provide a satisfactory weatherproof seal, a rubber strip is often attached around the edges of the doors. This standard container, locking mechanism, and seal are well known to those skilled in the art.
Unfortunately the lock rods and hinges for said pivoting doors, and the weatherproof seals are 3 o particularly prone to becoming damaged during transit. It is not uncommon for both the locking mech~ni~m~ and/or the hinges to become so badly damaged during transit that the doors cannot be opened when the container reaches its destination. Similarly, if the seals are damaged, the load can become, among others things, darnp during transport spoiling the contents of the container.
.
5 Such a delay in being able to open these freight containers can be extremely costly for a number of reasons. For example, numerous person hours can be lost while thermal cutting equipment is located and used to open the container. In the case of perishable items, such as foodstuffs, often the load spoils in the period before the container can be opened. Also the entire locking mech~ni.cm and/or hinges and/or seals must be replaced before the shipping container can be 1 o reused.
By way of example, freight containers known in the shipping industry as 'mini-containers' are widely used to transport supplies onto offshore oil-rigs from a helicopter. Weather conditions can be extreme, causing said mini-container to collide with the rig. The resultant impact(s) frequently 5 render the container impossible to open. Hence, there is an urgent need to protect the locking mech~nisms and moisture seals on the mini-containers used to transport supplies to offshore oil rlgs.
Accordingly, there is a need for a simple and inexpensive means of protecting the locking rod 2 o mech~ni.~m~ hinges, and weatherproof seals on freight containers. The invention described herein is sufficiently adaptable to be able to answer this urgent need for a wide variety of prior art container door constructions.
SUl~IMARY OF T~E INVENTION
The present invention provides reinforced protective shields to cover the locking rod mechanism and mounting brackets, hinges, and the rubber seals on container doors thereby preventing mechanical damage during shipping. A major advantage of the present invention is that it is possible to weld these protective shields onto existing container doors rather than replacing the 3 o entire door, hinge, seal, or locking mech~ni~m The objects and advantages of the protective shields, or plates, described in this patent include, but are not limited to the following: (a) to provide a means of protecting specific areas of freight 0~00 ~05 .
5 containers, which are particularly prone to mechanical darnage during shipping; (b) to provide a means of protecting the locking rods on freight containers from mechanical damage; (c) to provide a means of protecting the locking rod mounting brackets on container doors from meclhanical damage; (d) to provide a means of protecting the moisture seals around the edges of container doors from mechanical damage; and (e) to provide a means of protecting the hinges on 10 freight containers from mechanical damage.
All of the above advantages can be achieved without adding significant time, costs, or weight to the c,ontainer, thereby making the present invention clearly advantageous.
15 A further objects of the present invention is to provide an inexpensive means of applying protective shields to the least robust areas of shipping containers. Hence, the invention can be attached, for example, by way of being welded, onto existing container doors rather than replacing the entire door. However, any means of attaching said shields are envisioned by the present invention.
Yet a further advantage of the present invention is that the sizes of the shields can be adapted to fit any and all sizes of freight container doors, from the 'mini-containers' up to and including the 48' shipping containers.
2 5 An additional advantage of the present invention is that the shields can be fabricated from cornmercially available products, thereby providing an economical solution to the problem as described. It can be seen that the protective shields are compact in design, and do not extend beyond the other door fittings. This is an important feature so that the freight containers can be stored in close proximity to other containers in the hold of a ship or the like, providing yet a 3 o further advantage of the invention.
Further objects and advantages of the invention will become apparent from the consideration of the drawings and the ensuing description.
