DESCRIPTION:

BRIEF SUMMARY
TECHNICAL FIELD

The present invention relates to pallets.


BACKGROUND ART

Pallets are used to support bases which allow for access to fork tines under the support base so that a forklift can lift the support base and any product supported directly or indirectly by the support base.
Pallets are used extensively in the transport industry. The most common type of pallet used is the wooden pallet. Unfortunately there are a number of problems associated with wooden pallets including shortness of life. Another problem is that it has become expensive to return bulky wooden pallets to the country of origin on account of their size.
Attempts have been made from time to time to come up with pallets of different configurations and/or of different materials or mixtures of materials which will provide an alternative to the traditional wooden pallets. Other pallet types have been made from a variety of materials, including corrugated metal, wire mesh, aluminium, fibre board and plastics.
See for example U.S. Design Pat. Nos. 256,007, 306,226 and U.S. Pat. No. 2,405,535.
U.S. Pat. No. 2,405,535 (Le Roy Weiss) discloses an adjustable pallet which allows by means of its construction increases in size by fairly small increments to accommodate different size boxes or groupings of boxes. It primarily comprises a skeletal support base on three parallel runners, an outer runner of which is at a distal end of support base defining slats, beams or the like which intermesh and are moveable longitudinally relative to like slats, beams or the like fixed to span between the other two runners. The product therefore, in one degree of freedom, is telescopic down to a size not much larger than the area defined by the slats, beams or the like of the two runners which are fixed relative one to the other. Contraction/expansion telescopically in another degree of freedom, ie. normal to the longitudinal extent of said slats, beams or the like is also disclosed.
We recognise a potential market for pallet forms (assemblies as a bare pallet or modified to cage, bin or the like forms) which provide for flexibility of use and compliance with the national Standards of a number of different countries while preferably providing for ease of repair by substitution of components thereof as and when the need arises. An ability to repair greatly enhances pallet life and lowers ultimate cost.
The Standards of countries vary and by way of example various Standards provide for the following pallet sizes in

It can be seen even on bare pallet size that the Japanese Standard JIS 0604 does not allow sizes allowed in other countries.
