Definitions

• This invention concerns a method for mechanically connecting two or more components together.
• the invention concerns components having key arrangements and keys of the key arrangements are retainable by a key connector such that the key connector clamps the components together to form a secure joint.
• That connecting mechanism comprises components having keyway arrangements and a keyway connector having keys retainable by the keyway arrangements so as to lock the components together to form a secure joint.
• the method comprises the steps of aligning the keyway arrangements of the first and second components such that the keyways provide a keyway passage extending longitudinally between the keyways, and extending the keyway connector longitudinally within the keyway passage such that the keyway connector engages the keyways of the keyway arrangements to lock the first and second components together.
• the inventors have now developed a new connecting mechanism that, although utilising keys and a keyway, operates in a different manner from the connecting mechanism described earlier in that it does not have a keyway passage extending longitudinally between keyways as such.
• the instant invention minimises or overcomes one or more of the component-joining problems referred to the specifications of international patent application number PCT/AU2008/000839 and Australian patent application number 2009248444, the entire contents of which are incorporated herein by way of cross-reference. For clarity, relevant passages of number 2009248444 are reproduced below.
• Plastic is a versatile material that can be rotationally cast, injection moulded, heated and vacuum or pressure formed and even draped over form-work to make a variety of shapes for various purposes.
• injection moulding is a preferred method because it is fast, energy efficient and gives more precision of shape and size. It is, however, limiting in that internal cavities can't be made without welding or gluing the components together.
• gluing is not normally successful, so welding or using mechanical compression fittings and seals is the only real joining alternative. Compression fittings are limited in how big they can be in practice because of expense.
• Adhesives and glues are another alternative, but like welding processes, these are usually messy, hazardous, require specific surface preparation and conditions, and typically provide permanent, non-reversible joints only.
• Drums and pails are commonly used for the storage of hazardous or messy liquids and powders. They must have positive seals that are robust, even when dropped. Commonly used bucket-type clips are prone to leakage, have a limited shelf life and once opened are no longer very effective. Threads provide a positive joining method but are expensive to mould, especially on large plastic components, and if they become too large they are very difficult to undo or tighten in real world conditions. Threads also are limited to use on circular joint face profiles with planar joint faces.
• the present inventors have now developed a general connecting method.
• the present inventors have now developed a general connecting method for connecting two or more components together which may be made of like or unlike plastics material, composites material or metals material or of any other suitable type of material.
• the connecting mechanism minimises or overcomes one or more of the component-joining problems referred to above.
• a method of connecting at least a first component and a second component together wherein each said component comprises at least one key arrangement extending along the component and keys of the key arrangement are spaced apart from one another, said method comprising the steps of: aligning the key arrangements of the first and second components such that aligned keys of the key arrangements extend generally in line with a common axis or ensuring alignment of the key arrangements of the first and second components such that aligned keys of the key arrangements extend generally in line with a common axis; and
• a key connector comprising at least one longitudinal keyway passage over the aligned keys generally in line with the common axis so that the keys extend within the keyway passage, are retained by the key connector, and the first and second components are clamped together.
• the present invention also relates to at least a first component, a second component and a key connector as defined above when used for the method according to the first aspect.
• Each key arrangement and its keys may extend along each component in any suitable way.
• the key arrangement may extend along a face, surface, edge, perimeter and/or periphery of the component.
• the form of each key arrangement will depend on the nature of each component and how they are to be connected to one another.
• Each key arrangement may be detachably connected to a remainder of the component, and this may be achieved in any suitable way.
• the key arrangement may comprise a body and keys extending from the body, and the body may be receivable within a groove, pocket or a fold of a panel of the component.
• the body may be mateable with the remainder of the component by way of male and female formations.
• male formations (locating lugs) of the body may press fit/friction fit with openings in the remainder of the component, or vice- versa.
• Such formations may also help correctly orientate the body and remainder of the component relative to each other.
• Each component may be of any suitable size, shape and construction, and may be made of any suitable material or materials.
• the component may be planar, angular, bent, arcuate, convex, concave, annular, discoid, cylindrical, rectangular or of any other simple or complex geometry.
• first and second components may in fact be different regions or sections of the one component. That is, the one component may have a first face, surface, edge, perimeter and or periphery etc. that requires connection to a second face, surface, edge, perimeter and/or periphery etc. Therefore, first, second and further components as used herein may equally relate to faces, surfaces, edges, perimeters and/or peripheries etc of the one and same component.
• Each component and key arrangement may be planar, angular, bent, arcuate, convex, concave, annular, tubular (circular or non-circular), discoid, conical, tapered, cylindrical, rectangular or of any other simple or complex geometry.
• Each component and key arrangement may consist of metal, an alloy, steel, polyurethane, plastics material, composites, wood and wood-based materials, ceramics or rubber or any combination of these. The key arrangement and component remainder of the component need not be made of the same material or materials.
• Each key arrangement may comprise any suitable number of keys and the keys may be of any suitable size, shape and construction, provided that they can extend within the keyway passage and be retained by the key connector so as to clamp the components together to form a secure joint.
• each key is in the form of a hook or node and the keyway passage/key connector is shaped so as to be retained by the hook or node.
• the key arrangements of the first and second components are aligned such that the keys generally extend in line with a common axis and this may be achieved in any suitable way.

• the keys and/or component edge may have the general appearance of a sine, square, triangle or sawtooth waveform, having both peaks and troughs.
• the keys of the key arrangements may intermesh with one another or not. If first and second components are to be connected together, then each key of the first component may be located immediately adjacent a key of the second component.
• More than two components may be connected together. For instance, if first, second and third components are to be connected together, then the key of one component may be flanked by a respective key of each other component, although this need not necessarily be the sequence of keys.
• Each component may have more than one key arrangement extending along the component. This would allow a component to be directly connected to two or more other components at the same time, thus enabling an endless number of complex structures to be assembled.
• the key connector may be of any suitable size, shape and construction, and may be made of any suitable material or materials.
• the key connector need not be made of the same material as the first and second components.
• the key connector may consist of metal, an alloy, steel, polyurethane, plastics material, composites, wood or wood-based materials, ceramics or rubber or any combination of these.
• the key connector may be of unitary construction or may comprise two or more detachably connected pieces. An end of a first key connector piece may interference fit with an end of an adjacent second key connector piece. Alternatively, one end of an annular key connector may interference fit with the other end of the same connector.
• the key connector has an elongate body and the longitudinal keyway passage extends the entire length of the body (from end to end of the body), although this need not be the case.
• the keyway passage could be discontinuous in one or more places between opposed ends of the body.
• the key connector may have more than one keyway passage. If so, then preferably a keyway passage extends along each longitudinal side of the body.

The position of the hooks may alternate from one side of the body to the other along a length of the body, or the hooks of one longitudinal side of the body may directly oppose hooks of the other longitudinal side of the body. With the hooks in this arrangement, the hooks may be slid into locking engagement with the keys or slid out of locking engagement with the keys. If the key connector body has spaced apart hooks, then the key connector may be removed from clamping engagement with the keys in a lateral direction between the keys when not in locking engagement with the keys.
• the keys and key connector may engage so that they may releasably unlock or they may engage so that they cannot be unlocked without destroying the joint. This may be achieved in any suitable way. They may also engage such that the key connector can be reversibly fixed or held to prevent it accidentally unlocking with stress cycling.
