Description

TITLE

Key and Key way Connectors

TECHNICAL FIELD

[0001] This invention concerns, inter alia, a method for mechanically connecting two or more components or component regions together. In one aspect, the invention concerns key and key way connectors that are each engageable with a component and, once engaged, can connect the components or different regions of the one component together. In anotlier aspect, the invention concerns key and keyway connectors that are themselves part of a component or components.

BACKGROUND ART

[0002] The construction of furniture, cabinetry, display and storage units and like structures usually entails connecting components together with glue, adhesives, nails, screws, bolts, rivets staples as well as other types of fasteners. This can be problematic as it can be time-consuming, labour-intensive and require the use of specialist tools and labor. Rat-pack and ready-to- assemble designed furniture goes some way to overcome the above-mentioned problems, but such furniture has its own problems in that the connections formed between components can be of inadequate strength and can be held together by point loads. Also, for tongue in groove arrangements/dovetail joints, the components must be made of wood (timber or particle board). Furthermore, the same above-mentioned problems are commonplace in existing panel, modular, temporary and pre-fabricated construction methods for buildings and structures as well as rigid and flexible construction materials. Industrial, processing and materials-handling, storage and packaging applications and equipment such as replaceable strips, plates, panels, piping and other such replaceable items that wear out during operation or use also require convenient and/or reusable connecting systems.

DETAILED DESCRIPTION OF THE INVENTION

[0018] It is to be understood that the following detailed description of the invention generally applies to all ten aspects of the invention as defined in the summary section, unless the context provides otherwise.

[0019] As mentioned in Ihe summary section above, the keyway connector and/or the key connector can be engageable with or part of at least one component. In one embodiment, the keyway connector can be engageable with a first component and the key connector can be engageable with a second component and the keys can be engageable with the keyways to lock the first and second components together. In another embodiment, the keyway connector and the key connector can be engageable with different regions of the one component. In yet another embodiment, the keyway connector and/or the key connector can be part of, including integrally formed as part of, at least one component, including the one and the same component. In yet another embodiment, the keyway connector and the key connector can function as clamping elements/compression plates whereby one or more components are clamped/compressed between them or otherwise clamped into position.

[0020] The keyway connector can be of any suitable size, shape and construction, and can be made of any suitable material or materials. Plastics material, metal (e.g. aluminium or steels), alloys, composites, urethanes, rubber and silicone are, for example, suitable materials. In fact, any material that can be moulded, cast, pressed, formed, machined or extruded can be a suitable material. The keyway connector can be fabricated in any desired length and can be cut or snapped to length prior to or after being engaged with a component.

[0021] The keyway connector can comprise any suitable number of keyways and the keyways can be of any suitable size, shape and construction, provided that they can provide a longitudinal keyway passage as well as engage the keys of the key connector. Preferably at least one keyway engages and retains at least one key. More preferably each key engages and is retained by a respective keyway. At least one keyway can be in the form of a hook and at least one key can be shaped so as to be retained by that hook. In a preferred embodiment, each keyway is in the form of a hook and each key is shaped so as to be retained by the hook.

[0022] Each keyway can have a connector-support portion and a key-retaining portion. The connector-support portion can extend alongside and optionally further beneath or above the key connector, and [he key-retaining portion can extend around a key. The key-retaining portion can be arcuate, angular or both, for example.

[0023] The keyway connector can comprise a keyway body. The keyway body can be of unitary construction or can comprise separate connectable pieces. If separate connectable pieces, the pieces can be hingedly connected to one another or not. The keyway body can be made of relatively inflexible material or flexible material. The keyway body can extend linearly or other than linearly. For example, the keyway body can be substantially linear or arcuate when viewed in plan. If flexible, it is possible that the keyway body can be bent into an appropriate longitudinal shape. If of unitary construction, the keyway body can be fabricated with weakened regions/lines such that adjacent longitudinal regions can be broken apart. The keyway body can be fabricated with a scale or measure so that the length of the keyway body can be readily determined and cut/broken to length, if required.

[0024] The keyway body can have a component-engaging face or surface and a key- engaging face or surface. These faces/surfaces may oppose one another but this need not be the case. The faces/surfaces may extend in substantially parallel planes or not.

[0025] The keyway body can be in the form of a strip, plate or block, for example. The keyway body can have a longitudinal axis that extends linearly, arcuately or annularly, for example. The keyways can be spaced at regular intervals relative to one another along the longitudinal axis or parallel with the longitudinal axis. The keyways can be spaced at regular intervals relative to one another along opposing longitudinal sides of the keyway body. This clearance between the longitudinal sides can provide the longitudinal keyway passage.

[0026] The keyway body can be in the form of a disc or other shapes, for example an elliptical half-shape, having a circumference and central axis, for example. The keyway body can have a longitudinal axis that extends arcuately or annularly, for example.

[0027] The keyways can stand proud of the keyway body. Alternatively, the keyways can be located within a recess of the keyway body or be a moulded feature of the keyway body. The keyways can stand proud of the key-engaging face or surface, or be flat or recessed relative to the key-engaging face or surface.

[0028] The keyway connector can comprise two or more discrete sets οτ groups of keyways that are separate from, one another. Each of these sets or groups can extend along the longitudinal axis or not.

[0029] The keyways can be spaced as opposing pairs relative to and transversely of the longitudinal axis of the keyway body, or the keyways can be spaced as non-opposing pairs relative to and transversely of the longitudinal axis of the keyway body. That is, if non-opposing pairs, they can have a staggered/offset/alternating spacing. A pair of opposed keys can engage and be retained by a pair of opposed keyways. The keyways can be spaced along the longitudinal axis such that a width of an interval between adjacent keyways along the longitudinal axis is substantially of the same width as a width of each adjacent keyway (ie. one pitch length). That is a width of an actual keyway is substantially the same as a spacing between adjacent keyways (in the direction of the longitudinal axis).

[0030] The keyway connector can comprise a round keyway body having a circumference and a central axis. The keyway connector can comprise regularly spaced keyways that extend annularly between the central axis and the circumference. The keyway connector can have directly opposed pairs of keyways (that is, directly opposed radially) between which extends a longitudinal circular keyway passage. An outer ring of keyways can comprise keyways that are spaced apart from one another. An inner ring of keyways can comprise keyways that are spaced apart from one another, and these can be radially aligned with the keyways of the outer ring. The outer and inner rings of keyways can be spaced each side and equidistantly from a longitudinal axis extending through the keyway passage such that a width of an interval between adjacent keyways is substantially of the same width as a width of each adjacent keyway (ie. one pitch length). Alternatively, the keyways can be spaced as non-opposing pairs relative to and transversely of the longitudinal circular keyway passage. That is, they can have a staggered/ offset/alternating s pac ing .

[0031] The longitudinal keyway passage can be continuous, substantially continuous or not continuous. That is, the longitudinal keyway passage can be discontinuous in places along its length. In some embodiments the longitudinal keyway passage is continuous. In other embodiments the longitudinal keyway passage is substantially continuous or discontinuous in one or more places.

[0032] The keyway connector can comprise a handle, lobe or grip surface extending from or along the keyway body. The keyway connector can have any suitable type of handle. The handle can extend almost the length of the keyway body but for some applications it can be located at or near one end only. The handle can have openings for fingers (or basic tool). The handle can be removable or engage with a variety of gripping surfaces that can be formed onto a suitable face of the keyway connector.

[0033] The keyway connector can comprise a structural component extending from or along the keyway body. This structural component can be, for example, planar, angular, bent, arcuate, convex, concave, annular, discoid, cylindrical, rectangular or of any other simple or complex geometry. This structural component can connect with, retain or strengthen another said component.

[0034] The key connector can be of any suitable size, shape and construction, and can be made of any suitable material or materials. Plastics material, metal (e.g. aluminium or steels), alloys, composites, urethanes, rubber and silicone are, for example, suitable materials. In fact, any material that can be moulded, cast, pressed, formed, machined or extruded can be a suitable material. The key connector need not be made of the same material as the keyway connector, nor the first and second components. The key connector can be fabricated in any desired length and can be cut to length prior to or after being engaged with or mounted to a component. The key connector can comprise a key connector body. The key connector body can be of unitary construction or can comprise separate connectable pieces. If separate connectable pieces, the pieces can be hingedly connected to one another or not. An end of a first key connector piece can inlerference fit with an end of an adjacent second key connector piece. Alternatively, one end of an annular key connector can interference fit with the other end of the same connector. The key connector body can be made of relatively inflexible material or flexible material. The key connector body can extend linearly or other than linearly. For example, the key connector body can be substantially linear or arcuate when viewed in plan. If flexible, it is possible that the key connector body can be bent into an appropriate longitudinal shape. If of unitary construction, the key connector body can be fabricated with weakened regions/lines such that adjacent longitudinal regions can be broken apart. The key connector body can be fabricated with a scale or measure so that the length of the key connector body can be readily determined and cut/broken to length, if required.

[0035] The key connector body can have a component-engaging face or surface and a keyway-engagmg face or surface. These faces/surfaces may oppose one another or not. The faces/surfaces may extend in substantially parallel planes or not. The key connector body can be in the form of a strip, plate or block, for example. The key connector body can have a longitudinal axis that extends linearly, arcuately or annularly, for example. The key body can be in the form of a disc or an elliptical half-shape having a circumference and central axis, for example. The key body can have a longitudinal axis that extends arcuately or annularly, for example.

[0036] The key connector can have a key body that extends from and/or along the key connector body. The key connector body and key body can be one and the same. The keys can be spaced at regular intervals relative to one another along the longitudinal axis or parallel with the longitudinal axis. The keys can be spaced at regular intervals relative to one another along opposing longitudinal sides of the key body.

[0037] The keys can stand proud of the key body or key connector body. Alternatively, the keys can be located within a recess of the key connector body or a moulded recessed feature of the key connector body. The keys can stand proud of the keyway-engaging face or surface, or be flat or recessed relative to the keyway-engaging face or surface.

[0038] The key connector can comprise two or more discrete sets of keys that are separate from one another. [0039] The keys can be spaced as opposing pairs relative to and transversely of the longitudinal axis of the key body, or the keys can be spaced as non-opposing pairs relative to and transversely of the longitudinal axis of the key body. That is, they can have a staggered/off set/alternating spacing. The keys can be spaced along the longitudinal axis such that a width of an interval between adjacent keys along the longitudinal axis is substantially of the same width as a width of each adjacent key (ie. one pitch length). That is a width of an actual key is substantially the same as a spacing between adjacent keys (in the direction of the longitudinal axis).

[0040] Preferably, each longitudinal side of the key body has a plurality of keys extending within the same plane and the keys are spaced apart from one another in accordance with the spacing of the keyways. An opposed key pair can engage and be retained by a pair of opposed keyways. With the keys in this arrangement, the keys can be slid within the keyway passage into locking engagement with the keyways or slid out of locking engagement with the keyways. If the keyways are in the form of hooks, then the keys can be removed from the keyway passage in a lateral direction when not in locking engagement with the keyways. This can be achieved by moving each key along the keyway passage to a space between adjacent keyways (ie. one pitch length).

[0041 ] The key connector can comprise a round key connector body having a circumference and a central axis. The key connector can comprise regularly spaced keys that extend annularly between the central axis and the circumference. In such as case, the key body can be in the form of a ring/annulus.

[0042] The key connector can comprise a handle, lobe or grip surface extending from or along the key connector body. The key connector can have any suitable type of handle. The handle can extend almost the length of the key connector body but for some applications it can be located at or near one end only. The handle can have openings for fingers (or basic tool). The handle can be removable or engage with a variety of gripping surfaces that can be formed onto a suitable face of the key connector.

[0043] The key connector can comprise a structural component extending from or along the key connector body. This structural component can be, for example, planar, angular, bent, arcuate, convex, concave, annular, discoid, cylindrical, rectangular or of any other simple or complex geometry. This structural component can connect with, retain or strengthen another said component.

[0044] One or more key and one or more keyway can comprise, on one or both of its ends, a smooth rounded, arcuate, filleted, tapered, chamfered or angular lead-in edge or surface. This lead-in edge or surface on one or both ends can provide an important self-aligning function of the connectors during assembly and also provide a means to function without hindrance by dimensional tolerance issues and alignment differences either from manufacture, transport, handling, fitment or during assembly. The lead-in edge or surface also enables the key and keyway to apply the required load for the specified joint by moving the keys relative to the keyways only one pitch length. By doing so the lead-in applies the required load along the entire length of the connection relative to the ease and friction fit of the two or tnore connectors or components being joined. The amount of friction applied per section of the join can be adjusted to ensure assembly is simple and efficient and in many cases requires simple hand tools (or in many cases can be performed by hand only) to lock and/or unlock the joint. These aspects of the present invention provide distinct advantages over existing similar methods such as dove-tail, C- shape, wedge-shape or other similar mechanical or connector type joins and mechanisms.

[0045 J As mentioned, the keyway connector can be engageable with a component and the key connector can be engageable with a component, and this can be achieved in any suitable way. That is, the keyway connector and key connector can each comprise at least one mount and the mount can be, for example, in the form of one or more of the following: a friction fit groove arrangement, a tongue in groove arrangement (friction lit or not), a stepped, barbed or seixated tapered face (to increase friction fit strength), a fastener such as a nail, screw, bolt, rivet or staple, a locator pin or lug locatable within a suitably sized opening, or an adhesive such as glue or a double-sided adhesive strip. If in a tongue in groove arrangement, the keyway body or key body can be in the form of a wedge-shaped tongue (when viewed on end) that is received within a suitably tapered groove in a component. Of course, alternatively the groove can extend along and within the keyway body or key body and the tongue can be provided by the component.

[0046] The keyway connector and key connector can be engageable with, or more positively mounted to, a face, surface, edge, perimeter and/or periphery of a component. As already mentioned, the keyway connector and key connector can mount within a groove, pocket, cut-out, recess or a fold of a component. [0047] As mentioned, the key connector and/or keyway connector can be part of, including an integral part of, a component. Such a component can be moulded, cast, pressed, formed, machined or extruded, for example.

[0048] More than two components can be connected together. More than one keyway connector or key connector can be engageable with or mounted to a component at any angle. This would allow a component to be directly connected to (including clamped to) two or more other components at the same time, thus enabling an endless number of complex structures to be assembled.

[0049] The keyway and key connector can engage so that they can be releasably unlocked or they can engage so that tbey cannot be unlocked without destroying the connection. This can be achieved in any suitable way. They can also engage such that the keyway connector can be reversibly fixed or held to prevent it accidentally unlocking with stress cycling. A lofted keyway profile can be used to achieve this or alternatively any number of other methods that will be obvious to those skilled in the art can be used, e.g. insertable keys, snap-fit connectors, tabs, grub screws or adhesive.

[0050] The connector assembly can comprise a locking mechanism for preventing a keyway connector from unintentionally moving relative to a key connector whilst joined together. In one embodiment, the keyway connector can comprise a frangible or hinged clip end portion that closely resembles a cross section of the keyway body having a pair of keyways, except that these keyways can be shaped so as to tightly hook around/clip over a pair of keys and immobilize the keyway connector. The clip end portion can be connected to the keyway body via a thin neck that can serve as a hinge or can snap off prior to assemblage or during assemblage when impacted such as with a hammer blow.

[0051 ] In another embodiment, the key connector can comprise a frangible or hinged locking end portion that closely resembles a cross section of the key connector except that it has a locking pin (instead of a key pair) that is extendible through an opening in a component. The locking pin can have a shaft and an enlarged head. When driven through the component opening, the head cannot be withdrawn because it is oversized and not able to be pulled through the opening. That is, the pin can engage an opening in the component and immobilize the key connector. The locking end portion can be connected to the key body via a thin neck that can serve as a hinge or can snap off prior to assemblage or during assemblage when impacted such as with a hammer blow.

[0052] The connecting method according to the fifth and sixth aspects can comprise the step of connecting the components together or different regions of the one component together using a further connecting mechanism. Such a mechanism can include mating male and female regions, such as, for example, a key and keyway arrangement, a tongue in groove arrangement, a snap-fit arrangement, a pin and hole arrangement and so forth being located between abutting faces or edges of the component s.

[0053] The connecting method according to the fifth or sixth aspects can further comprise the step of introducing a sealing member between the components or component regions before connecting them together, so as to render the connection fluid-tight. Any suitable type of seahng member can be used (e.g. a gasket or O-ring or other profile seal). A sealing member can be extended along abutting faces or edges of the components or of the one and same component.

[0054] Alternatively, abutting faces or edges of the components themselves (or component itself) can be shaped to provide a sealing function. For example, one or more of the components can have an integrally formed (eg. moulded) sealing member or profile to enable improved sealing of the joi nt.

[0055] Each component can be of any suitable size, shape and construction. Each component can be rigid, semi-rigid or flexible and can be made of any suitable material or materials. The component can be planar, angular, bent, arcuate, convex, concave, annular, discoid, cylindrical, tubular, rectangular or of any other simple or complex geometry. The component can be, for example, a panel, beam, tube, pipe, film, fabric, cloth, mesh, textile, netting, membrane, container, closure for the container, cylindrical wall section of a tank, base or roof connectable to the wall section of the tank, slip flange assembly for holding pipes or tubes in general together, or strip, plate, panel screen or lining section, part or assembly for structures or equipment used in industrial processing, mineral processing, mill liners, excavation tool or equipment or materials handling equipment or similar applications. This list is not exhaustive and other general component types are mentioned elsewhere in this specification as well as in the applicant's other published applications, including PCT/AU200S/000839, PCT/AU2010/000240 and PCT/AU201 1/000759.

[0056] The connector can be used for butt joining components together or for forming mitered joints (ie. for components having bevelled edges), or both. In this embodiment, any suitable number of additional panels or beams can be connected to the first and second components so as to form, for example, floors, plates, panels, screens or strips, form-work, scaffolding, architectural beams, sub-assemblies, linings, ceilings, facades, covers, skins, mats, automotive components, aerospace components, frames, cabinetry, displays, shop fit-outs, storage, packaging and materials handling applications, shelters, playground equipment, and other types of equipment, machinery, building elements, furniture or structures.

[0057] The keyway connector and key connector can clamp one or more components between their respective key connector and keyway bodies. The key connector body or keyway body can extend through coinciding openings in two or more components and key connector bod)' and keyway body can function as clamping elements when connected together.

[0058] In one embodiment, one or more components can be a generally L-shaped panel. The panel can have an upper channel/groove, a lower tongue and two side-by-side clampable regions located between the channel/groove and tongue. A first clampable region can have one or more openings sized to receive keys and keyways. A second clampable region can have one or more openings sized to receive keys and keyways. The panels can comprise strengthening crosspieces/webs extending between the channel/groove and tongue. An opening in the first clampable region can allow two or more like panel components to be clamped together. In order to join the panels together, the keys of a key connector and/or keyways of a keyway connector can be extended through coinciding openings in the panels. Once the connectors are connected together, the panels can be clamped together by way of clamping loads provided by the keyway body and the key body. A panel can be stackable atop a like panel in that the tongue of one panel can engage the channel/groove of an adjacent panel.

[0059] In another embodiment, one or more components can be a flanged half-pipe. The half-pipe can have a ribbed body (although the ribbing is optional) and a flange extending longitudinally along each side of the body. Each flange can extend radially or non-radially from the body. Each flange can extend from the body externally of the half pipe, or from the body internally within the half pipe. Each flange can have one or more openings sized to receive keys and/or keyways. In order to join the flanges together, the keys of a key connector and/or ke ways of a keyway connector can be extended through coinciding openings in the flanges. Once the connectors are connected together, the flanges can be clamped together by way of clamping loads provided by the keyway body and the key body. [0060] In another embodiment, the connector assembly can be used to join two longitudinal edges of a split pipe together. The split pipe can have a ribbed body (although the ribbing is optional) and a flange extending along and from each longitudinal edge of the body. Each flange can extend radially or non-radially from the body. Each flange can extend externally of the body externally of the split pipe, or from the body internally within the split pipe. Each flange can have one or more openings sized to receive keys and/or keyways. In order to join the flanges together, the keys of a key connector and/or keyways of a key way connector ca be extended through coinciding openings in the flanges. Once the connectors are connected together, the flanges can be clamped together by way of clamping loads provided by the keyway body and the key body.

[0061 ] In another embodiment, the connector assembly can be used to join two tube/pipe hose ends together. The connector assembly can also be used to join one tube/pipe/hose end to another component such as a valve, junction, inlet port, outlet port or tube/pipe/hose connection applications. Alternatively, one or both of the flanged tube/pipe/hose ends can be in the form of spigots.

[0062] hi such an embodiment, the keyway connector can comprise a keyway body having a circumference, central axis and an opening located within the circumference and having a centre coinciding with the central axis. The opening can be sized to receive and retain a flanged tube/pipe/hose, whereby the flange abuts an inner shoulder/edge of the keyway body. Alternatively, the flanged tube/pipe/hose end can be in the form of a flanged spigot that extends through the opening.

The key connector can comprise regularly spaced keys and key body that extend annularly between the central axis and the circumference and proud from the body. The keys can be equally spaced apart from one another such that a width of an interval between adjacent keys is substantially of the same width as a width of each adjacent key (ie. one pitch length).

[0068 J Each keyway can be in the form of a hook and each key can be shaped so as to be retained by the hook, but this need not necessarily be the case. The keys can be radially aligned with the keyways such that the keys can be snugly received within the round keyway passage of the key body. The connectors can be rotated relative to one another one pitch length, such that the keys engage and can be retained/hooked by the keyways. Each keyway and each key can have on one or both of its ends a rounded or angular lead-in edge or surface.

[0069] In another embodiment, the connector assembly can be used to butt join different types of components together, such as frames, furniture, beams, panels, cabinetry and displays. The connector assembly can comprise a keyway connector and a key connector. The keyway connector can comprises at least first, second and third sets of regularly spaced keyways and the key connector can comprise at least first, second and third sets of regularly spaced keys that engage respective keyway sets to lock the connectors together.

[0070] The keyway connector can comprise a keyway body having a longitudinal axis. A component-abutting face of the body can be substantially flat, as can a key-abutting face of the body. The keyway body can have at least three discrete recessed regions in the key-abutting face extending along the longitudinal axis that provide the at least three sets of keyways. Non- recessed regions extending transversely of the longitudinal axis between the recessed regions can act as strengthening ribs in the axial direction and can be load bearing. f 0071 ] Openings spaced along each longitudinal side of the keyway body can be adapted to receive fasteners such as screws or nails so that the keyway body can be fastened to a component requiring joining. Typically, the keyway body may be mounted to a component within a shallow recess of the component such that the key-abutting face is flush with a surface of the component that will be joined to another component.

The keys can bulge/extend from the key body transversely of the longitudinal axis. Each keyway and each key can have on one or both of its ends a rounded or angular lead-in edge or surface.

[0075] Openings spaced along each longitudinal side of the key connector body can be adapted to receive fasteners such as screws or nails so that the key connector body can be fastened to a component requiring joining. Typically, the key connector body would be mounted to a component within a shallow recess of the component such that the keyway-abutting face is flush with a surface of the component that will be joined to another component.

[0076] The connector assembly can comprise a locking mechanism for preventing the keyway connector from unintentionally sliding relative to the key connector whilst joined together. The locking mechanism can be of any suitable design. The keyway connector can comprise a resilient locking tab and the key connector can comprise a pocket in a part of the key body between a pair of opposed keys for receiving the locking tab when the key and keyway connector have been joined together.

[0077] in a locking position the locking tab can be biased to extend within the pocket and prevent the keys from shifting position within the keyway passage. In an unlocked position, the locking tab can disengage the pocket and enable the keys to slide within the keyway passage. An opening in a sidewall of the keyway body can provide tool access to the locking tab so that the tab can be pressed toward the component-abutting face against the bias (ie. against the force of the leaf spring).

[0078] In order to connect the connectors together, the keyway connector and key connector can be brought into engagement with one another and then moved relative to one another one pitch length, such that the keys engage and are retained/hooked by the keyways. Once in position, the locking tab can automatically spring into position, projecting within the key body pocket.

Each keyway can be in the form of a hook and each key can be shaped so as to be retained by the hook, but this need not necessarily be the case.

[0081] The keyway connector can comprise a keyway body having a longitudinal axis. A component-abutting face of the body can be substantially flat, as can be a key-abutting face of the body. The keyway body can comprise a recessed region (ie. molded recess) in the key-abutting face extending along the longitudinal axis that provides the keyways.

[0082] The keyway connector can comprise opposed pairs of keyways, between which extends a longitudinal keyway passage, along the longitudinal axis.

The keys can be spaced parallel with the longitudinal axis such that a width of an interval between adjacent keys is substantially of the same width as a width of each adjacent key (ie. one pitch length). The keys can bulge/extend from the key body transversely of the longitudinal axis. Each keyway and each key can have on one or both of its ends a rounded or angular lead-in edge or surface.

[0086] Openings spaced along each longitudinal side of the key connector body and key body can be adapted to receive fasteners such as screws or nails so that the key connector body can be fastened to a component requiring joining. Typically, the key connector body may be mounted to a component within a shallow recess of the component such that the keyway-abutting face is flush with a surface of the component that will be joined to another component.

[0087] The connector assembly can comprise a locking mechanism for preventing the keyway connector from unintentionally sliding relative to the key connector whilst joined together. The locking mechanism can be of any suitable design. The keyway connector can comprise a resilient locking tab and the key connector can comprise a pocket in part of the key body between a pair of opposed keys for receiving the locking tab when the key and keyway connector have been joined together.

[0088] In a locking position the locking tab can be biased to extend with the pocket and prevents the keys from shifting position within the keyway passage. In an unlocked position, the locking tab can disengage the pocket and enable the keys to slide within the keyway passage. An opening in a sidewall of the keyway body can provide tool access to the locking tab so that the tab can be pressed toward ihe componeni-abutting lace againsi the bias (ie. against the force of the leaf spring).

[0089] In order to connect the connectors together, the keyway connector and key connector can be brought into engagement with one another and then moved relative to one another one pitch length, such that the keys engage and are retained/hooked by the keyways. Once in position, the locking tab can automatically spring into position, projecting within the key body pocket.

[0090] In another embodiment, the connector assembly can be used to connect two panel components (such as mesh panel components) and a rail/frame member together. Each panel can comprise a pair of opposed ends that can abut like ends of other panels when assembled. Each panel end can comprise a pair of recesses, each of which can have a shoulder against which the keyway connectors can bear. The rail/frame member can be part of a larger frame to which the panels can be mounted. Such an assembly can be used as vibrating screens for minerals processing, for example. [00 1] The connector assembly can comprise one or more keyway connectors and/or key connectors. Each keyway connector can comprise regularly spaced keyways and the key connector can comprise regularly spaced keys that engage the keyways to lock the connectors together. Each keyway can be in the form of a hook and each key can be shaped so as to be retained by the hook, but this need not necessarily be the case.

[0092] Each keyway connector can comprise a keyway body having a longitudinal axis. The body can be block-shaped and elongate. The keyway body can comprise a substantially flat component-abutting face/edge that bears against a shoulder of a panel.

[0093] Each keyway connector can comprise opposed pairs of keyways, between which extends a longitudinal keyway passage, along the longitudinal axis. The keyways can be spaced parallel with the longitudinal axis such that a width of an interval between adjacent keyways is substantially of the same width as a width of each adjacent keyway (ie. one pitch length).

[0094] The key connector can comprise a key connector body in the form of a strip that has a longitudinal axis, a keyway-abulting face and a component-abutting face. The abutting faces of the connector body can be substantially flat.

[0096] The key connector may also comprise mounting lugs (rail-locator pins) spaced along and extending perpendicularly from the component-abutting face. These lugs can be locatable within and securable within openings in the rail. However, other connecting mechanisms may be used. Typically, the key connector body would be mounted to the rail such that the keyway- abutting face is unhindered so as to be able to engage the keyway.

[0097] The connector assembly can comprise a locking mechanism for preventing each keyway connector from unintentionally sliding relative to the key connector whilst joined together. Each keyway connector comprises a frangible or hinged clip end portion that closely resembles a cross section of the keyway body having a pair of keyways, except that these keyways are shaped so as to tightly hook around/clip over a pair of keys and immobilize the keyway connector. The clip end portion can be connected to the keyway body via a thin neck that can serve as a hinge or can snap off prior to assemblage or during assemblage when impacted such as with a hammer blow.

[0098J In order to connect the panel and rail components together, the key connector can be first mounted to the rail by way of the mounting lugs (or other means). The panels and keyway connectors can then be oriented such that the component-abutting face of each keyway body engages a shoulder of a panel, and the keyway connectors can then be engaged with the key connector. The connectors can then be moved relative to the key connector one pitch length, such that the keys engage and are retained/hooked by the keyways. The connectors and panels can then be locked into position following a hammer blow to each clip end portion.

[0099] In another embodiment, the connector assembly can be used to connect two panel components (such as a panel mesh component) and a rail/frame member. Each panel can comprise a pair of opposed ends that can abut like ends of other panels when assembled. Each panel end can comprise a recess that can have a shoulder, against which the key connector can bear. The rail/frame member can be part of a larger frame to which panels like those illustrated in the figures can be mounted. Such an assembly can be used as vibrating screens for minerals processing or similar screening applications.

[00100] The connector assembly can comprise a keyway connector and a key connector. The keyway connector can comprise regularly spaced keyways and the key connector can comprise regularly spaced keys that engage the keyways to lock the connectors together. Each keyway can be in the form of a hook and each key can be shaped so as to be retained by the hook, but this need not necessarily be the case.

[00101 ] The keyway connector can comprise a keyway body having a longitudinal axis and a substantially flat component-abutting face that can bear against the rail.

[00102] The keyway connector can comprise opposed pairs of keyways, between which extends a longitudinal keyway passage, along the longitudinal axis. The keyways can be spaced parallel with the longitudinal axis such that a width of an interval between adjacent keyways is substantially of the same width as a width of each adjacent keyway (ie. one pitch length).

[00103] The keyway connector can comprise mounting lugs (rail-locator pins) spaced along and extending perpendicularly from the component-abutting face. These lugs can be locatable within and securable within openings in the rail.

[00104] The key connector can comprise a key connector body in the form of a block that has a longitudinal axis and a component-abutting face. The abutting face of the connector body can be substantially flat and can bear against the shoulder of the panel.

[00105] The key connector body can comprise keys and a key body that stand proud of the abutting face of the key connector body. The key connector can have opposed pairs of keys each side of the key body. The key body and key connector body can extend in-line with the longitudinal axis. The keys can be spaced parallel with the longitudinal axis such that a width of an interval between adjacent keys is substantially of the same width as a width of each adjacent key (ie. one pitch length). The keys can bulge/extend from the key body transversely of the longitudinal axis.

[00106] Each keyway and each key can have on both of its ends a rounded or angular lead-in edge or surface.

[00107] The connector assembly can comprise a locking mechanism for preventing each key connector from unintentionally sliding relative to the keyway connector whilst joined together. The key connector can comprise a frangible or hinged locking end portion that closely resembles a cross section of die key connector except that it has a locking pin (instead of a key pair) that is extendible through an opening in the rail. The locking pin can comprise a shaft and an enlarged head. When driven through the rail opening, the head may not be withdrawn because it is oversized and not able to be pulled through the opening. That is, the pin can engage an opening in the rail and immobilize the key connector. The locking end portion can be connected to the key body via a thin neck that can serve as a hinge or can snap off prior to assemblage or during assemblage when impacted such as with a hammer blow.

[00108] In order to connect the panel and rail components together, the keyway connector can be first mounted to the rail by way of the mounting lugs (or other connecting mechanism). The panels and key connector can then be oriented such that the component-abutting face of the key body engages a shoulder of a panel, and the key connector can then be engaged with the keyway connector. The key connector can then be moved relative to the keyway connector one pitch length, such that the keys engage and are retained/hooked by the kevways. The connectors and panels can then be locked into position following a hammer blow to the locking end portion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS [00267] In the figures, like reference numerals refer to like features.

[00268] Referring first to figures 1 - 13. there is shown a connector assembly 1 (shown assembled in figure 10) that can be used to join (clamp) different types of components together, such as sub-assemblies, formwork, shoring, jackets, frames and furniture. The connector assembly 1 comprises a keyway connector 2 and a key connector 3. Both connectors 2, 3 may be made of plastics material, urethanes, rubber, alloys or steel.

[00269] The keyway connector 2 comprises first 4 and second 5 sets of regularly spaced keyways 4a, 4b, 5a, 5b (only some of which have been labeled, as seen in figures 1 and 7) and the key connector 3 comprises first 7 and second 8 sets of regularly spaced keys 7a, 7b, 8a, 8b (as seen in figures 1 and 7, only some of which have been labeled) that engage respective keyway sets 4, 5 to lock the connectors 2, 3 together. Each keyway 4a, 4b, 5a, 5b of each keyway set 4, 5 is in the form of a hook and each key 7a, 7b, 8a, 8b is shaped so as to be retained by the hook, but this need not necessarily be the case.

[00270] The keyway connector 2 comprises a keyway body 10 having a longitudinal axis. The body 10 is elongate and has rounded ends. An upper face 11 of the body is substantially flat, as is a lower face 12 of the body 10. The two sets of keyways 4, 5 stand proud of the upper face 1 1 of the body 10 and each set 4, 5 comprises an upstanding wall 4c, 5c that encircles that set of keyways 4, 5.

[00271 ] Each keyway set 4, 5 has opposed pairs of keyways 4a, 4b, 5a, 5b (as best seen in figures 1 and 7), between which extends a longitudinal keyway passage 4d, 5d, along the longitudinal axis (as seen in figure 7). The keyways 4a, 4b, 5a, 5b are spaced parallel with the longitudinal axis such that a width of an interval 4e, 5e (not all labeled) between adjacent keyways 4a, 4b, 5a, 5b is substantially of the same width as a width of each adjacent keyway 4a, 4b, 5a, 5b (ie. one pitch length).

[00272] The keyway body 10 serves as a cl mping element/plate.

[00273] The key connector 3 comprises a key body 15 having a longitudinal axis, an upper face 1 and a lower face 17 (as seen in figures 1 and 2). The key body 15 is elongate and has upturned ends. The key connector 3 has a handle 18 that extends from the upper face 16 of the key body 15, from each upturned end, above the key body 15, and along a length of the key body 15. The key connector 3 further comprises strengthening crosspieces/webs 19 that extend between the handle 18 and the upper face 16 of the key body 15, between the ends of the key body 15. [00274] The key connector 3 may further comprise a grip 20a, 20b for fingers of a user that extends from each end of the handle 18. This grip 20a, 20b area may also serve as a striking region to aid assemblage and disassembly of the connecting mechanism 1.

[00275] The two sets of keys 7, 8 stand proud of the lower face 17 of the key body 15. Each key set 7, 8 has opposed pairs of keys 7a, 7b, 8a, 8b that extend along the longitudinal axis. The keys 7a, 7b, 8a, 8b are spaced parallel with the longitudinal axis such that a width of an interval 7c, 8c between adjacent keys 7a, 7b, 8a, 8b is substantially of the same width as a width of each adjacent key 7a, 7b, 8a, 8b (ie. one pitch length), as seen in figure 4.

[00276] The key body 15 (lower face 17 thereof) serves as a clamping element/plate.

[00277] Each keyway 4a, 4b, 5a, 5b and each key 7a, 7b, 8a, 8b has on both of its ends a rounded or angular lead-in edge or surface 4f, 5f, 7f, 8f (as partially shown in figures 1 and 2). This lead-in edge or surface 4f, 5f, 7f, 8f provides an important self-aligning function of the connectors 2, 3 during assembly. The lead-in edge or surface 4f, 5f, 7f, 8f also enables the key 7a, 7b, 8a, 8b and keyway 4a, 4b, 5a, 5b to apply the required load for the specified joint by moving the keys 7a, 7b, 8a, 8b relative to the keyways 4a, 4b, 5a, 5b only one pitch length. By doing so the lead-in 4f, 5f, 7f. 8f applies the required evenly distributed load along the entire length of the joint relative to the ease and friction fit of the connectors 2, 3 being joined. The keys 7a, 7b, 8a, 8b are spaced apart from one another in accordance with the spacing of the keyways 4a, 4b, 5a, 5b. With the keys 7a, 7b, 8a, 8b in this arrangement, the keys 7a, 7b, 8a, 8b can be slid into locking engagement with the keyways 4a, 4b, 5a, 5b or slid out of locking engagement with the keyways 4a, 4b, 5a, 5b. The keys 7a, 7b, 8a, 8b can be removed from the keyway passage 4d, 5d in a lateral direction when not in locking engagement with the keyways 4a, 4b, 5a, 5b. This can be achieved by moving each key 7a, 7b, 8a, 8b along the keyway passage 4d, 5d to a space 4e, 5e between adjacent keyways 4a, 4b, 5a, 5b (ie. one pitch length).

[00278] In order to connect the connectors 2, 3 together, the keyway connector 2 and key connector 3 are first brought into engagement with one another as shown in the joining sequence depicted in figures 8 and 9. The connectors 2, 3 are then moved relative to one another one pitch length, such that the keys 7a, 7b, 8a, 8b engage and are retained/hooked by the keyways 4a, 4b, 5a, 5b, as shown sequentially in figures 9 and 10.

[00279] Referring now to figures 14-21, these show how the connectors 1 can be used to join panels 22, 22a, 22b, 22c, 22d {formwork panels) to each other. One panel shape 22 is shown in figures 14-17 and can be joined to arrive at the configurations illustrated in figures 18-20. In order to join the panels 22, the keys 7a, 7b, 8a, 8b of a key connector 3 and keyways 4a, 4b, 5a, 5b of a keyway connector 2 are extended through appropriately sized pairs of openings 23, 24 in the panels 22. Once the connectors are connected together, the panels are clamped together as illustrated in figures 18-20. Figure 21 shows configurations A, B, C, D, E and F, which consist of panel types 22a, 22b, 22c and 22d.

[00280J The panels 22 shown in figures 14- 17 are generally L-shaped. Each panel 22 has an upper channel/groove 25, a lower tongue 26 and two side-by-side clampable regions 27, 28 located between the channel/groove 25 and tongue 26. A first clampable region 27 has seven pairs of slots/openings 24, all of which are sized to receive keys 7a, 7b, 8a, 8b and keyways 4a, 4b, 5a, 5b. A second clampable region 28 has a single pair of openings 23 sized to receive keys 7a, 7b, 8a, 8b and keyways 4a, 4b, 5a, 5b. The panels 22 also comprise crosspieces/webs (not labeled) extending between the channel/groove 25 and tongue 26. The opening pairs 24 of the first clampable region 27 allow two panels 22 to be connected together in different ways, as seen in figures 18 and 19. The panels 22 are stackable atop like panels 22 in that the tongue 26 of one panel 22 engages the channel/groove 25 of an adjacent panel 22, as seen in figure 20.

[Ό0281] Referring now to figures 22-36, these show how the connectors 1 can be used to join flanged half-pipes 31 a, 31 b, 32a, 32b, 33a, 33b to each other. Each half-pipe 31 a, 31 b, 32a, 32b shown in figures 22-31 has a ribbed body 31c, 32c (although the ribbing is optional) and a flange 3 I d, 32d extending longitudinally along each side of the ribbed body 31c, 32c as well as generally radially from the body 31c, 32c. The flanges 3 Id, 32d have openings 31e, 32e, as seen in figures 23 and 28. In figures 22-26 the flanges 3 I d extend externally of the body 31c. In figures 27-31 the flanges 32d extend internally of the body 32c.

[00282] In order to join the flanges 3 Id, 32d together, the keys of a key connector 3 and keyways of a keyway connector 2 are extended through appropriately sized pairs of openings 31e, 32e in the flanges 3 Id, 32d. Once the connectors 2, 3 are connected together, the flanges 3 I d, 32d are clamped together by way of clamping loads provided by the keyway body 10 and the key body 15, as seen in figures 26 and 31.

[00283] The half-pipe 33a, 33b embodiment of figures 32-36 differs from those detailed above in that it does not have a ribbed body 33c and the flanges 33d do not extend generally radially relative to the body 33c. However, the flanges 33d are connected together essentially in the same way described above.

[00284] Referring now to figures 37-43, these show how the connectors 1 can be used to join two longitudinal edges of a split pipe 35, 36 together. Rather than being half-pipes, these pipes 35, 36 are spilt along their length and a flange 35d, 36d extends generally radially from a longitudinal edge of the body 35c, 36c. The body 35c of figures 37-40 is ribbed and the flanges 35d extend externally of the body 35c, whereas the body 36c of figures 41-43 is not ribbed and extends internally of the body 36c, generally radi lly of the body 36c.

[00285] In order to join the flanges 35d, 36d together, the keys of a key connector 3 and keyways of a keyway connector 2 are extended through appropriately sized pairs of openings in the flanges 35d, 36d. Once the connectors 2, 3 are connected together, the flanges 35d, 36d are clamped together by way of clamping loads provided by the keyway body 10 and the key body 15, as seen in figures 40 and 43.

[00286] Referring to figures 44-58 there is shown a connector assembly 40 (shown assembled in figures 44-47) that can be used to join two flanged tube/pipe/hose ends 41, 42 together. The connector assembly 40 can also be used to join one tube/pipe/hose end to another component such as a valve, inlet port or outlet. Alternatively, the two flanged tube/pipe hose ends 41 , 42 can be in the form of spigots. The connector assembly 40 comprises a keyway connector 43 as seen in figure 58 and a key connector 44 as seen in figure 54. Both connectors 43, 44 may be made of plasties material, urethanes, silicon, rubber, alloys or steel.

[00287] Referring now to figures 55-58, the keyway connector 43 comprises a (elliptical half- shape) keyway body 45 having a circumference 46, central axis and a round opening 47 located within the circumference 46 and having a centre coinciding with the central axis. The opening 47 is sized to receive and retain a flanged tube/pipe/hose 42, whereby the flange 42a abuts an inner shoulder/edge of the keyway body 45 as seen in figures 47 and 50. Alternatively, the flanged tube/pipe/hose end 42 can be in the form of a flanged spigot that extends through the opening 47. Alternatively, the tube/pipe/hose may have plain ends only.

[00288] The keyway connector 43 comprises regularly spaced keyways 48, 49 (not all of which have been labeled) that extend annularly around the flanged tube/pipe/hose/spigot 42 between the central axis and the circumference 46. Tine keyway connector 43 has directly opposed pairs of keyways 48, 49 (that is, directly opposed radially) between which extends a longitudinal circular keyway passage 50. An outer ring of keyways 48 comprises keyways 48 that are spaced apart from one another. An inner ring of keyways 49 comprises keyways 49 that are spaced apart from one another, and these can be radially aligned with the keyways of the outer ring 48. The outer and inner rings 48, 49 of keyways are spaced each side and equidistantly from a longitudinal axis extending through the keyway passage 50 uch that a width of an interval between adjacent keyways 48, 49 is substantially of the same width as a width of each adjacent keyway 48, 49 (ie. one pitch length). The keyways 48, 49 are of unitary construction with the body 45.

[00289] The key connector 44 comprises a key connector body 51 (shown here as an elliptical half-shape) having a circumference 52, central axis and a round opening 53 located within the circumference 52 and having a centre coinciding with the central axis, as best seen in figures 47, 49 and 51-54. The opening 53 is sized to receive and retain a flanged tube/pipe/hose 41, whereby the flange 41a abuts an inner shoulder/edge of the key body 51, as seen in figures 47 and 49. Alternatively, the flanged tube/pipe/hose end 41 can be in the form of a rolled or grooved end or flanged spigot that extends through the opening 53.

[00290] The key connector body 51 has an annular groove 55 having a centre coinciding with the central axis and the groove extends between the flanged tube/pipe/hose/spigot 41 and the circumference 52, as seen in figure 52. The groove 55 has a longitudinally extending central axis (ie. an imaginary ring). The groove 55 has a radial width sized so as to snugly receive the keyways 48, 49 of the keyway connector 43.

[002 1 ] The key connector 44 comprises regularly spaced keys 56a, 56b (not all of which have been labeled) and a key body 57 that extend annularly within the groove 55 along the imaginary ring and from the imaginary ring (ie. proud of the imaginary ring). The keys 56a, 56b are equally spaced apart from one another such that a width of an interval between adjacent keys 56a, 56b is substantially of the same width as a width of each adjacent key 56a, 56b (ie. one pitch length). The keys 56a, 56b are of unitary construction with the key body 57 and key connector body 51. The key body 57 extends as a ring between the opposed pairs of keys 56a, 56b and to the key connector body 51. [00292] Each kcyway 48, 49 is in the form of a hook and each key 56a, 56b is shaped so as to be retained by the hook, but this need not necessarily be the case. The keys 56a, 56b can be radially aligned with the keyways 48, 49 of the inner and outer rings such that the opposed pairs of keyways 48, 49 can be snugly received within the groove 55 of the key connector body 51.

[00293] Each keyway 48, 49 and each key 56a, 56b has on both of its ends a rounded or angular lead-in edge or surface 48f, 49f, 56af, 56bf as described for an earlier embodiment. The keys 56a, 56b are spaced apart from one another in accordance with the spacing of the keyways 48, 49. With the keys 56a, 56b in this arrangement, the keys 56a, 56b can be slid into locking engagement with the keyways 48, 49 or slid out of locking engagement with the keyways 48, 49. The keys 56a, 56b can be removed from the keyway passage 50 in a lateral direction when not in locking engagement with the keyways 48, 49. This can be achieved by moving each key 56a, 56b along the keyway passage 50 to a space between adjacent keyways 48, 49 (ie. one pitch length).

[00294] In order to connect the connectors 43, 44 together, the keyway connector 43 and key connector 44 are first brought into engagement with one another, such that the keyways 48, 49 are received within the groove 55 of the key connector body 51. The connectors 43, 44 are then rotated relative to one another one pitch length, such that the keys 56a, 56b engage and are retained/hooked by the keyways 48, 49, as shown in figure 47. When joined, the flanged ends 41a, 42a of the tubes/pipes/hoses/spigots 41 , 42 abut in a fluid-tight manner, as seen in figures 44,45 and 47.

[00295] Referring to figures 59-69 there is shown a connector assembly 60 (shown assembled in figures 60-63) having a round connecting mechanism for joining components together. The connector assembly 60 comprises a keyway connector 61 as seen in figure 67 and a key connector 71 as seen in figure 64. Both connectors 61 , 71 can be made of plastics material.

[00296] The keyway connector 61 comprises a round keyway body 62 having a circumference 63 and a central axis. The keyway connector 61 comprises regularly spaced keyways 64a, 64b (not all of which have been labeled) that extend annularly between the central axis and the circumference 63. The keyway connector 61 has directly opposed pairs of keyways 64a, 64b (that is, directly opposed radially) between which extends a longitudinal circular keyway passage 65. An outer ring of keyways 64a comprises keyways 64a that are spaced apart from one another. An inner ring of keyways 64b comprises keyways 64b that are spaced apart from one another, and these can be radially aligned with the keyways 64a of the outer ring. The outer and inner rings of keyways 64a, 64b are spaced each side and equidistantlv from a central axis extending through the keyway passage 65 such that a width of an interval between adjacent keyways 64a, 64b is substantially of the same width as a width of each adjacent keyway 64a, 64b (ie. one pitch length). The keyways 64a, 64b are of unitary construction with the keyway body 62.

[00297] The key connector 71 comprises a round key connector body 72 having a circumference 73 and a central axis. The key connector 71 comprises regularly spaced keys 74a, 74b (not all of which have been labeled) and key body 75 that extend annularly between the central axis and the circumference 73 and proud of the body 72. The keys 74a, 74b are equally spaced apart from one another such that a width of an interval between adjacent keys 74a, 74b is substantially of the same width as a width of each adjacent key 74a, 74b (ie. one pitch length). The keys 74a, 74b are of unitary construction with the key body 75 and key connector body 72.

[00298] Each keyway 64a, 64b is in the form of a hook and each key 74a, 74b is shaped so as to be retained by the hook, but this need not necessarily be the case. The keys 74a. 74b can be radially aligned with the keyways 64a, 64b of the inner and outer rings such that the keys 74a, 74b can be snugly received within the round keyway passage 65 of the keyway body 62.

[00299] Each keyway 64a, 64b and each key 74a, 74b has on both of its ends a rounded or angular lead-in edge or surface, as described for an earlier embodiment. The keys 74a, 74b are spaced apart from one another in accordance with the spacing of the keyways 64a, 64b. With the keys 74a, 74b in this arrangement, the keys 74a, 74b can be slid into locking engagement with the keyways 64a, 64b or slid out of locking engagement with the keyways 64a, 64b. The keys 74a. 74b can be removed from the keyway passage 65 in a lateral direction when not in locking engagement with the keyways 64a, 64b. This can be achieved by moving each key 74a, 74b along the keyway passage 65 to a space between adjacent keyways 64a, 64b (ie. one pitch length).

[00300] In order to connect the connectors 61, 71 together, the keyway connector 61 and key connector 71 are first brought into engagement with one another as shown in figure 59 such that the keys 74a, 74b are received within the longitudinal circular keyway passage 65 of the keyway body 62. The connectors 1, 71 are then rotated relative to one another one pitch length, such that the keys 74a, 74b engage and are retained/hooked by the keyways 64a, 64b, as shown in figure 63. [00301 j ft is to be appreciated that the round connecting mechanism (ie. annular keys and keyways) can be associated with, or of unitary construction with, any suitably shaped key and keyway body. The bodies can be components themselves, be directly incorporated into component functions such as lids for containers or plugs or similar or further connectable to other components.

[00302] Referring to figures 70-86, there is shown a connector assembly 80 (shown assembled in figure 83) that can be used to butt join or face join different types of components together, such as frames, furniture, beams, panels, ceilings, covers, components, cabinetry and displays. The connector assembly 80 comprises a keyway connector 81 as seen in figure 76 and a key connector 1 as seen in figure 72 Both connectors 81 , 91 are made of plastics material.

[00303] The keyway connector 81 comprises first 82, second 83 and third 84 sets of regularly spaced keyways 82a, 82b, 83a, 83b, 84a, 84b (as seen in figure 76) and the key connector 91 comprises first 92, second 93 and third 94 sets of regularly spaced keys 92a, 92b, 93a, 93b, 94a, 94b that engage respective keyway sets 82, 83, 84 to lock the connectors 81 , 1 together. Each keyway 82a, 82b, 83a, 83b, 84a, 84b of each key way set 82, 83, 84 is in the form of a hook and each key 92a, 92b, 93a, 93b, 94a, 94b is shaped so as to be retained by die hook, but this need not necessarily be the case.

[00304] The keyway connector 81 comprises a keyway body 86 having a longitudinal axis. The body 86 is elongate and has rounded ends. A component-abutting face 87 of the body 86 is substantially flat, as is a key-abutting face 88 of the body 86. The keyway body 86 has three discrete recessed regions (ie. molded recesses) in the key-abutting face 88 extending along the longitudinal axis that provide the three sets of keyways 82, 83, 84. Non-recessed regions extending transversely of the longitudinal axis between the recessed regions act as strengthening ribs in the axial direction and are load bearing (as seen in figure 78).

[00305] Openings 89 spaced along each longitudinal side of the keyway body 86 (see figure 76) are adapted to receive fasteners such as screws or nails so that the keyway body 86 can be fastened to a component requiring joining. Typically, the keyway body 86 may be mounted to a component within a shallow recess of the component such that the key-abutting face 88 is flush with a surface of the component that will be joined to another component.

[00306] Each keyway set 82, 83, 84 has two opposed pairs of keyways 82a, 82b, 83a, 83b, 84a, 84b, between which extends a longitudinal keyway passage 90a, 90b, 90c (see figure 76), along the longitudinal axis. The keyways 82a, 82b, 83a, 83b, 84a, 84b are spaced parallel with the longitudinal axis such that a width of an interval between adjacent keyways 82a, 82b, 83a, 83b, 84a, 84b is substantially of the same width as a width of each adjacent keyway 82a, 82b, 83a, 83b, 84a, 84b (ie, one pitch length).

[00307] The key connector 91 comprises a key connector body 96 having a longitudinal axis, a component-abutting face 97 and a keyway-abutting face 98. The connector body 96 is elongate and has rounded ends. The component-abutting face 97 of the connector body 96 is substantially flat, as is the keyway-abutting face 98.

[00308] The key connector 91 has three discrete sets of keys 92, 93, 94 that stand proud of the keyway-abutting face 98. Each key set 92, 93, 94 has two opposed pairs of keys 92a, 92b, 93a, 93b, 94a, 94b each side of a key body 92c, 93c, 94c that extends in-line with the longitudinal axis. The keys 92a, 92b, 93a, 93b, 94a, 94b are spaced parallel with the longitudinal axis such that a width of an interval between adjacent keys 92a, 92b, 93a, 93b, 94a, 94b is substantially of the same width as a width of each adjacent key 92a, 92b, 93a, 93b, 94a, 94b (ie. one pitch length). The keys 92a, 92b, 93a, 93b, 94a, 94b bulge/extend from the key body 92c, 93c, 94c transversely of the longitudinal axis.

[00309] Openings 103 spaced along each longitudinal side of the key connector body 96 (as shown in figure 72) are adapted to receive fasteners such as screws or nails so that the key connector body 96 can be fastened to a component requiring joining. The key connector body 96 or keyway connector body 86 may also be attached to a component requiring joining by way of other means such as rivets, adhesives, double-sided adhesive tapes or other suitable means. The key connector body 96 or keyway connector body 86 may be mounted to a component within a shallow recess of the component such that the respective abutting face is flush with a surface of the component that will be joi ned to another component.

[00310] Each keyway 82a, 82b, 83a, 83b, 84a, 84b and each key 92a, 92b, 93a, 93b, 94a, 94b has on both of its ends a rounded or angular lead-in edge or surface, as described in respect of an earlier embodiment. The keys 92a, 92b, 93a, 93b, 94a, 94b are spaced apart from one another in accordance with the spacing of the keyways 82a, 82b, 83a, 83b, 84a, 84b. With the keys 92a, 92b, 93a, 93b, 94a, 94b in this arrangement, the keys 92a, 92b, 93a, 93b, 94a, 94b can be slid into locking engagement with the kcyways 82a, 82b, 83a, 83b, 84a, 84b or slid out of locking engagement with the keyways 82a, 82b, 83a, 83b, 84a, 84b. The keys 92a, 92b, 93a, 93b, 94a, 94b can be removed from the keyway passage 90a, 90b, 90c in a lateral direction when not in locking engagement with the keyways 82a, 82b, 83a, 83b, 84a, 84b. This can be achieved by moving each key 92a, 92b, 93a, 93b, 94a, 94b along the keyway passage 90a, 90b, 90c to a space between adjacent keyways 82a, 82b, 83a, 83b, 84a, 84b (ie. one pitch length).

[0031 1] The connector assembly 80 also comprises a locking mechanism for preventing the keyway connector 81 from unintentionally sliding relative to the key connector 91 whilst joined together. The keyway connector 81 comprises a resilient locking tab 105 and the key connector 91 comprises a pocket 106 in a part of the key body 92c between a pair of opposed keys 92a, 92b for receiving the locking tab 105 when the key 81 and keyway 91 connector have been joined together.

[00312] In a locking position the locking tab 105 is biased to extend within the pocket 106 and prevents the keys 92a, 92b, 93a, 93b, 94a, 94b from shifting position within the keyway passage 90a, 90b, 90c. In an unlocked position, the locking tab 105 disengages the pocket 106 and enables the keys 92a, 92b, 93a, 93b, 94a, 94b to slide within the keyway passage 90a, 90b, 90c. An opening 107 in a sidewall of the keyway body 86 provides tool access to the locking tab 105 so that the tab 105 can be pressed toward the component-abutting face 87 against the bias (ie. against the force of the leaf spring).

[00313] In order to connect the connectors 81, 91 together, the keyway connector 81 and key connector 1 are first brought into engagement with one another as shown in figure 80. The connectors are then moved relative to one another one pitch length, such that the keys 92a, 92b, 93a, 93b, 94a, 94b engage and are retained/hooked by the keyways 82a, 82b, 83a, 83b, 84a, 84b, as shown in figure 83. Once in position, the locking tab 105 automatically springs into position, projecting within the key body pocket 106.

[00314] Referring to figures 87- 101 there is shown a connector assembly 1 10, like that of the earlier described embodiment, that can be used to butt join different types of components together, such as sub-assemblies, frames, furniture, beams, panels, cabinetry and displays. The connector assembly 110 comprises a keyway connector 111 as seen in figure 91 and a key connector 121 as seen in figure 87. Both connectors 11 1, 121 can be made of plastics material. [00315] The keyway connector 1 1 1 comprises regularly spaced keyways 1 1 2a, 1 12b (not all of which have been labeled) and the key connector 121 comprises regularly spaced keys 122a, 122b that engage the keyways 1 12a, 1 12b to lock the connectors 1 1 1 , 121 together. Each keyway 1 12a, 1 12b is in the form of a hook and each key 122a, 122b is shaped so as to be retained by the hook, but this need not necessarily be the case.

[00316] The keyway connector 1 11 comprises a keyway body 1 13 having a longitudinal axis. The body 113 is elongate and has rounded ends. A component-abutting face 1 14 of the body 113 is substantially flat, as is a key-abutting face 1 15 of the body. 1 1 3 The keyway body 1 1 3 has a recessed region (ie. molded recess) in the key-abutting face 1 15 extending along the longitudinal axis that provides the keyways 1 12a, 1 12b.

[00317] The keyway connector 1 1 1 comprises opposed pairs of keyways 1 12a, 1 12b, between which extends a longitudinal keyway passage 117, along the longitudinal axis. The keyways 1 12a, 1 12b are spaced parallel with the longitudinal axis such that a width of an interval between adjacent keyways 1 12a, 1 1 2b is substantially of the same width as a width of each adjacent keyway 112a, 112b (ie. one pitch length).

[00318] Openings 1 18 spaced along each longitudinal side of the keyway body 1 13 and within the keyway passage 117 are adapted to receive fasteners such as screws or nails so that the keyway body 1 13 can be fastened to a component requiring joining. Typically, the keyway body 1 13 can be mounted to a component within a shallow recess of the component such that the key- abutting face 115 is flush with a surface of the component that will be joined to another component.

[00319] The key connector 121 comprises a key connector body 123 having a longitudinal axis, a component-abutting face 124 and a keyway-abutting face 125. The connector body 123 is elongate and has rounded ends. The component-abutting face 124 of the connector body 123 is substantially flat, as is the keyway-abutting face 125.

[00320] The key connector 121 has keys 122a, 122b that stand proud of the keyway-abutting face 125. The key connector 121 has opposed pairs of keys 122a, 122b each side of a key body 127 that extends in-line with the longitudinal axis. The keys 122a, 122b are spaced parallel with the longitudinal axis such that a width of an interval between adjacent keys 122a, 122b is substantially of the same width as a width of each adjacent key 122a, 122b (ie. one pitch length). The keys 122a, 122b bulge/extend from the key body 127 transversely of the longitudinal axis.

[00321] Openings 129 spaced along each longitudinal side of the key connector body 123 and key body 127 are adapted to receive fasteners such as screws or nails so that the key connector body 123 can be fastened to a component requiring joining. Typically, the key connector body 123 may be mounted to a component within a shallow recess of the component such that the keyway-abutting face 125 is flush with a surface of the component that will be joined to another component.

[00322] Each keyway 1 12a, 1 12b and each key 122a, 122b has on both of its ends a rounded or angular lead-in edge or surface, as described for an earlier embodiment. The keys 122a, 122b are spaced apart from one another in accordance with the spacing of the keyways 1 12a, 1 12b. With the keys 122a, 122b in this arrangement, the keys 122a, 122b can be slid into locking engagement with the keyways 1 12a, 112b or slid out of locking engagement with the keyways 1 12a, 1 12b. The keys 122a, 122b can be removed from the keyway passage 1 17 in a lateral direction when not in locking engagement with the keyways 1 12a, 1 12b. This can be achieved by moving each key 122a, 122b along the keyway passage 117 to a space between adjacent keyways 122a, 122b (ie. one pitch lengtii).

[00323] The connector assembly 110 also comprises a locking mechanism for preventing the keyway connector 1 1 1 from unintentionally sliding relative to the key connector 121 whilst joined together. The keyway connector 1 1 1 comprises a resilient locking tab 130 and the key connector 121 comprises a pocket 13 1 in part of the key body 127 between a pair of opposed keys 122a, 122b for receiving the locking tab 130 when the key and keyway connector 1 1 1, 121 have been joined together.

[00324] In a locking position the locking tab 130 is biased to extend with the pocket 131 and prevents the keys 122a, 122b from shifting position within the keyway passage 1 17. In an unlocked position, the locking tab 1 30 disengages the pocket 131 and enables the keys 122a, 122b to slide within the keyway passage 1 17. An opening 132 in a sidewall of the keyway body 1 13 provides tool access to the locking tab 130 so that the tab 1 0 can be pressed toward the component-abutting face 114 against the bias (ie. against the force of the leaf spring).

[00325] In order to connect the connectors 1 1 1 , 121 together, the keyway connector 1 1 1 and key connector 121 are first brought into engagement with one another as shown in figure 95. The connectors 1 1 1 , 121 are then moved relative to one another one pitch length, such that the keys 122a, 122b engage and are retained/hooked by the keyways 112a, 112b, as shown in figure 98. Once in position, the locking tab 1 0 automatically springs into position, projecting within the key body pocket 131.

[00326] Figures 102-1 15 show two panel components 140a, 140b and a rail/frame member

141 that are to be connected together using a connector assembly 142. Each panel 140a, 140b has a pair of opposed ends that can abut like ends of other panels 140 when assembled. Each panel end has a pair of recesses 143a, 143b. 143c, 143d, each of which has a shoulder 144a, 144b, 144c, 144d against which keyway connectors of the connector assembly 142 can bear. The rail/frame member 141 is part of a larger frame to which panels 140 like those illustrated can be mounted. Such an assembly of panels 140, rails/frame members 141 and connector assemblies

142 can be used as vibrating screens for minerals processing or similar industrial screening applications.

[00327] The connector assembly 142 comprises two identical keyway connectors 150a, 1 0b and a key connector 160 as seen in figure 102. All connectors 150, 160 can be made of plastics material, methanes, composites, ceramics, alloys, steels, rubber or any other suitable materials.

[00328] Each keyway connector 150a, 150b comprises regularly spaced keyways 151a, 15ib and the key connector 160 comprises regularly spaced keys 161 a, 161 b (not all of which have been labeled) that engage the keyways 151 a, 151 b to lock the connectors 150, 160 together. Each keyway 151a, 151b is in the form of a hook and each key 161a, 161b is shaped so as to be retained by the hook, but this need not necessarily be the case.

[00329] Each keyway connector 150a, 150b comprises a keyway body 152 having a longitudinal axis. The keyway body 152 is block-shaped and elongate. The keyway body 152 has a substantially flat component-abutting face/edge 154 that bears against a shoulder 144 of a panel 140 as shown in figures 103 and 104 (shoulders 144b and 144c are shown only).

[00330] Each keyway connector 150a, 150b comprises opposed pairs of keyways 151a, 151b, between which extends a longitudinal keyway passage 155, along the longitudinal axis. The keyways 151 a, 151 b are spaced parallel with the longitudinal axis such that a width of an interval between adjacent keyways 151 a, 151 b is substantially of the same width as a width of each adjacent keyway 151a, 151b (ie. one pitch length). [003 1 j The key connector 160 comprises a key connector body 163 in the form of a strip that has a longitudinal axis, a keyway-abutting face 164 and a component-abutting face 165. The abutting faces 164, 165 of the connector body 1 3 are substantially flat.

[00332] The key connector 160 has keys 161a, 161b and a key body 167 that stand proud of the keyway-abutting face 164 of the key connector body 163. The key connector 160 has opposed pairs of keys 161a, 161b each side of the key body 167, and the key body 167 extends from the key connector body 163 in-line with the longitudinal axis. The keys 161a, 161b are spaced parallel with the longitudinal axis uch that a width of an interval between adjacent keys 161a, 161 b is substantially of the same width as a width of each adjacent key 161a, l61b (ie. one pitch length). The keys 161 a, 161b bulge/extend from the key body 167 transversely of the longitudinal axis.

[00333 J The key connector 160 may also comprise mounting lugs 169 (rail- locator pins) spaced along and extending perpendicularly from the component-abutting face 165. These lugs

169 as shown in figure 1 13 are locatable within and securable within openings in the rail 141. However, other connecting mechanisms may be used. Typically, the key connector body 163 would be mounted to the rail 141 such that the keyway-abutting face 164 faces upwardly.

[00334] Each keyway 151a, 151b and each key 161a, 161b has on both of its ends a rounded or angular lead-in edge or surface. This lead-in edge or surface provides an important self- aligning function of the components during assembly, as described above. The keys 161 a, 161b are spaced apart from one another in accordance with the spacing of the keyways 151 a, 151b. With the keys 161a, 161b in this arrangement, the keys 161 a, 161 b can be slid into locking engagement with the keyways 151 a, 151b or slid out of locking engagement with the keyways 151 a, 151b. The keys 161 a, 161b can be removed from the keyway passage in a lateral direction when not in locking engagement with the keyways 151a, 151b. This can be achieved by moving each key 161 a, 161b along the keyway passage to a space between adjacent keyways 151 a, 151 b (ie. one pitch length).

[00335] The connector assembly 142 also comprises a locking mechanism for preventing each keyway connector 150 from unintentionally sliding relative to the key connector 160 whilst joined together. Each keyway connector 150 comprises a frangible or hinged clip end portion

170 that closely resembles a cross section of the keyway body 152 having a pair of keyways 151 a, 151b, except that these keyways 171a, 171 b are shaped so as to tightly hook around/clip over a pair of keys 16ia, 161b and immobilize the keyway connector 160. For ease of mould- based manufacture, the clip end portion can be connected to the keyway body 152 via a thin neck 173 that can serve as a hinge or can snap off prior to assemblage or during assemblage when impacted such as with a hammer blow.

[00336] In order to connect the panel 140a, 140b and rail 141 components together, the key connector 160 is first mounted to the rail 141 by way of the mounting lugs 169 (or other means). The panels 140 and keyway connectors 150a, 150b are then oriented such that the component- abutting face 154 of each keyway body 152 engages a shoulder 144 of a panel 140a, 140b, and the keyway connectors 150a, 150b are then engaged with the key connector 160, basically as can be gleaned from figures 102 and 103. The connectors 150a, 150b are then moved relative to the key connector 160 one pitch length, such that the keys 161a, 161b engage and are retained hooked by the keyways 151a, 151b, as shown in figure 103. The connectors 150a, 150b, 160 and panels 140a, 140b are then locked into position following a hammer blow to each clip end portion 170.

[00337] Figures 116-130 show two panel components 180a, 180b and a rail/frame member 181 that are to be connected together using a connector assembly 184, similar in concept to that shown in the earlier figures. Each panel 180a, 180b has a pair of opposed ends that can abut like ends of other panels when assembled. Each panel end 185a, 185b has a recess that has a shoulder 186a, 186b, against which a key connector 200 of the connector assembly 184 can bear. The rail/frame member 181 is part of a larger frame to which panels 180a, 180b like those illustrated can be mounted. Such an assembly of panels 180, rails/frame members 181 and connector assemblies 184 can be used as vibrating screens for minerals processing or similar industrial screening applications.

[00338] The connector assembly 184 comprises a keyway connector 190 and a key connector 200 as seen in figure 121. Both connectors 190, 200 can be made of plastics material, urethanes, composites, ceramics, alloys, steels or rubber.

[00339] The keyway connector 190 comprises regularly spaced keyways 191a, 191b and the key connector 200 comprises regularly spaced keys 201a, 201b that engage the keyways 191a, 191b to lock the connectors 190, 200 together. Each keyway 191a, 191 b is in the form of a hook and each key 201 a, 201b is shaped so as to be retained by the hook, but this need not necessarily be the case.

[00340] The keyway connector 190 comprises a keyway body 193 having a longitudinal axis and a substantially flat component-abutting face 194 that bears against the rail 181 as shown in figure. 1 18.

[00341] The keyway connector 190 comprises opposed pairs of keyways 191a, 191b, between which extends a longitudinal keyway passage 195, along the longitudinal axis. The keyways 191a, 191b are spaced parallel with the longitudinal axis such that a width of an interval between adjacent keyways 1 1 a, 191 b is substantially of the same width as a width of each adjacent keyway 191a, 191b (ie. one pitch length).

[00342] The keyway connector 190 comprises mounting lugs 197 (rail-locator pins) spaced along and extending peipendicularly from the component-abutting face 194. These lugs 197 are locatable within and securable within openings in the rail 181.

[00343] The key connector 200 comprises a key connector body 203 in the form of a block that has a longitudinal axis and a component-abutting face 204. The abutting face 204 of the connector body 203 is substantially flat and can bear against the shoulder 186a, 186b of the panel 180, 180b.

[00344] The key connector 200 has keys 201a, 201b and a key body 205 that stand proud of the abutting face 204 of the key connector body 203. The key connector 200 has opposed pairs of keys 201a, 201b each side of the key body 205. The key body 205 and key connector body 203 extend in-line with the longitudinal axis. The keys 201a, 201b are spaced parallel with the longitudinal axis such that a width of an interval between adjacent keys 201a, 201b is substantially of the same width as a width of each adjacent key 201a, 201b (ie. one pitch length). The keys 201 a, 201b bulge/extend from the key body 205 transversely of the longitudi nal axis.

[00345] Each keyway 191a, 191b and each key 201a, 201b has on both of its ends a rounded or angular lead-in edge or surface, as described above.

[00346] The connector assembly 184 also comprises a locking mechanism for preventing each key connector 200 from unintentionally sliding relative to the keyway connector 190 whilst joined together. The key connector 200 comprises a frangible or hinged locking end portion 207 that closely resembles a cross section of the key connector body 203 except that it has a locking pin 208 (instead of a key pair) that is extendible through an opening in the rail 181. The locking pin 208 has a shaft 209 and an enlarged head 210. When driven through the rail 181 opening, the head 210 cannot be withdrawn because it is oversized and not able to be pulled through the opening. That is, the pin 208 can engage an opening in the rail 181 and immobilize the key connector 200. For ease of mould-based manufacture, the locking end portion 207 can be connected to the key connector body 203 via a thin neck 212 that can serve as a hinge or can snap off prior to assemblage or during assemblage when impacted such as with a hammer blow.

[00347] In order to connect the panel 180a, 180b and rail 181 components together, the keyway connector 190 is first mounted to the rail 181 by way of the mounting lugs 197 (or other connecting mechanism). The panels 180a, 180b and key connector 200 are then oriented such that the component-abutting face 204 of the key connector body 203 engages a shoulder 186a, 186b of a panel 180a, 180b, and the key connector 200 is then engaged with the keyway connector 190 as can be gleaned from figures 116-120. The key connector 200 is then moved relative to the keyway connector 190 one pitch length, such that the keys 201a, 201b engage and are retained/hooked by the keyways 191a, 191b, as shown in figures 117-120. The connectors 190, 200 and panels 180a, 180b are then locking into position following a hammer blow to the locking end portion 207.

[00348] Some of the advantages of each embodiment as exemplified are listed below.

[00349] Figures 1- 13: The embodiment provides a means of locking together a number of components in a fast, safe and simple manner. In one simple locking action, the connector system shown provides a strong and secure joint along a relatively long distance, thereby providing a uniform load and a complete joint in one process. The embodiment shown here has two sets of key and keyway connectors in the one assembly, thereby providing mote than twice the linear joining distance possible over one key and keyway connector segment. However, this system can utilise one, two or more sets of key and keyway connector pairs to provide the optimum joining operation efficiencies. The embodiment is designed to be intuitive to use and negates the need for highly skilled operators and technical equipment and can be locked and unlocked using simple hand tools only.

[00350] Figures 14-21 : Whilst the concept of reusable, modular construction formwork is not new and has been proven to be a very cost-effective method of construction for many decades, the embodiment improves on this principal and enables a more efficient assembly/disassembly (erection/strip) process for each concrete pour, thus saving considerable time and costs of construction including labour and specialist equipment costs as well as related site costs such as cranage and concrete pumping equipment and the like. A further advantage of the embodiment is that the modular design provides many different combinations of pile sizes and dimensions, thereby greatly reducing the number of different components of the system, thus reducing manufacture costs and also providing the user with greatly flexibility on the job. The more uniformly loaded joint area (as described above in paragraph 00318) enables the use of less materials and often lighter weight materials to be used as compared to existing modular formwork systems as the current key and keyway connector provides a more evenly distributed load at the join zone when compared to formwork systems utilizing bolts, pins, wedges, handle- pins and other similar methods that all rely on high numbers of fixture points to accommodate the loads involved during use. This advantages of the key and keyway systems are multiplied during reuse and multiple uses of the components, f00351] Figures 22-36: These figures illustrate several variations of use of formwork, culverts, structures, piping repair, piping reinforcement and reinstatement, pile reinforcement and repair, insulation and other suitable uses of mostly cylindrical applications that benefit from the same and other similar advantages as described in above paragraph 00319 as well as having the sections in more easily stacked configuration for more efficient storage and transport. In addition to having a more effective and more evenly distributed load across the joint by way of the key and keyway connectors, the reduction in the number of loose parts is advantageous as it reduces the risk of losing small and fiddly bolts, pins, wedges and handle-pins and similar during operation on construction sites, remote locations on land or marine applications and other hostile conditions and environments.

[00352] Figures 37-43: These figures encompass all of the advantages as described in paragraphs 00 18, 00319 and 00320 and are shown here using only one axial join which provides the advantage of only having to open/close one axial joint to create the cylindrical shape required. That is, joining two edges of the same component. As shown this can be a joint enabled by wa of an internal or external joint of the tubular or cylindrical component.

[00353] Figures 44-58: These figures illustrate a key and keyway configuration that has advantages over a traditional threaded connector as it provides a higher strength connection but only requires a very small radial rotation of keys to the keyways, whereby a threaded connection must rotate at least several full revolutions to provide adequate connection. Also, the embodiment provides a stronger connection that a conventional bayonet style connector by way of having keyway hooks on both sides of the radial axis line, whereas bayonet style connectors only provide connection restraint behind one side of the radial axis line (either internal or external).

[00354] Figures 59-69: All of the advantages as described in paragraph 00322 similarly apply to these figures 59-69 to provide a faster and stronger means of connection.

[00355] Figures 70-86: The embodiment as illustrated in these figures provides a fast, reusable, safe and secure method of connecting and fixing two or more components together without the need for any tools. The embodiment also provides an aesthetically pleasing and often invisible means of connection thereby very beneficial for displays, stands, facades, boxes, ceilings, cabinetry, furniture, framing and other similar applications. The design provides a high level of self-alignment which is particularly advantageous when assembling, erecting or building components or structures or similar with access from only one side. As noted in the description above, this design provides additional longitudinal load-bearing capacity against the three or more individual cross-members.

[00356] Figures 87-101 : The embodiment as illustrated in these figures provides a fast, reusable, safe and secure method of connecting and fixing two or more components together without the need for any tools. The embodiment also provides an aesthetically pleasing and often invisible means of connection thereby very beneficial for displays, stands, facades, boxes, ceilings, cabinetry, furniture, framing and other similar applications. The design provides a high level of self-alignment which is particularly advantageous when assembling, erecting or building components or structures or similar with access from only one side.

[00357] Figures 102-1 15: With any screen panel or wear plate application, it is common to use systems utilizing such conventional means as threaded fastener, fastener-rail (eg: tee or square headed bolts in a channel), locking pin and pin-sleeve type arrangements as a means of holding the panels in place. The embodiment is advantageous over all of these as it provides a longer/broader hold-down force over a greater area of the panel whilst at the same time being extremely fast to carry out installation or removal of modular panels. This means that fewer key and keyway connectors are required to provide a stronger and more secure means of fixing and securing the panel into position and also requiring less labour-time. The embodiment is also suitable and compatible with existing systems and have means of securing to the rails, structure or equipment proper thereby enabling easy interchangeability. The embodiment also provides a safer installation and removal process, as personnel access is only required by one side of the panel, by one person only, requiring simple hand tools only to carry out the complete procedure. Furthermore, being a modular system allows singular change-out or rotation of individual modular panels when worn, without disrupting, loosening or having to remove adjoining panels or fixing systems.

[00358] Figures 116-130: With any screen panel or wear plate application, it is common to use systems utilizing such conventional means as threaded fastener, fastener-rail (eg: tee or square headed bolts in a channel), locking pin and pin-sleeve type arrangements as a means of holding the panels in place. The embodiment is advantageous over all of these as it provides a longer/broader hold-down force over a greater area of the panel whilst at the same time being extremely fast to carry out installation or removal of modular panels.
