BACKGROUND ART Many forms of garment hanger are known. Likewise many forms of clamping device useful as a clothes peg or useful in holding one or more sheets of material are known (e. g. including those with a magnet for attachment to refrigerators).

The present invention relates to an alternative to those currently known.

In its preferred form the present invention relates to a form of garment hanger (by term "garment"is included any item that might be usefully clamped and held by the hanger) and the term"hanger"refers to any device (with or without a hook) engageable by hanging or otherwise to some form of support capable of supporting an item in turn carried or supported by the hanger.

One form of hanger that finds favour is one incorporating two pairs of jaws, each pair of jaws having one jaw stationary relative to the main body of the hanger and the other jaw moveable relative thereto, whereby opposite sides of, for example, a trouser leg can be gripped by the respective pairs of jaws of the hanger.

The present invention relates to an improved form of such a clamping device and/or hanger and to related methods of manufacture of all of the clamp or hanger or the main moulded component thereof and related uses of such a component.

The present invention recognises an advantage can be derived from the provision of a single moulded component which has the capability of being associated for each clamping device, (ie; for each pair of jaws) with an appropriate biasing member. The present invention also recognises an advantage is available particularly for garment hangers where a more rigid mouldable material (e. g.; a plastics material) can be utilised over a flexible material (usually plastics) since a greater bulking up of certain regions of the overall hanger will not be necessary with the more rigid material of lesser bulk owing to its inherent stiffness and loading support capability.

By way of example, if a moulded component of a relatively stiff plastics material such as a suitable styrene can be moulded as a single component as opposed to an articulating flexible material such as a polypropylene that will requiring bulking up for the loading supporting regions there is an immediate manufacturing advantage.

In preferred forms of the present invention therefore the present invention is directed to enhancements in componentry, assemblies made using such componentry, collapsed but in assembly forms of such componentry taking advantage of the features hereafter to be described, related processes and tooling and uses of any such processes, tooling, components, subassemblies and assemblies.

SUMMARY OF THE INVENTION In one aspect the present invention consists in a garment hanger having at least one component that has been moulded in a plastics material and two biasing component, wherein the or a moulded component alone has provided or still provides two pairs of linked jaws, and wherein each biasing component biases each pair of jaws to a clamping condition from which condition they can be released by reproducible relative movement of the jaws against the bias.

In a further aspect the present invention consists in a garment hanger wherein the moulded component has defined a link between jaws which subsequently has or has been reconfigured by one or more of flexure, plastic deformation and rupture.

Preferably the links define in their reconfigured state a pivot between the jaws.

In other forms the links can reconfigure, deform, rupture, etc. to allow free movement of the jaws under the control of the biasing component.

In another aspect the invention consists in a clamping device assembled from a moulded component and a biasing component or components ("biasing component"), wherein said moulded component defines in the assembled device two jaws (relatively) openable from a clamping condition against the bias provided by the biasing component from whence they can be allowed to close or almost close ("close") (relatively) under such bias to a clamping condition.

Preferably said moulded component has or has had at least prior to assembly an integral link, one jaw to the other, in the material from which the moulded component has been created.

Preferably in use the link can assume (e. g. by flexure and/or collapse) a stable relationship to provide a reactive force in part against the bias and to provide a fulcrum effect.

Preferably said link includes a region adapted to distort or otherwise reconfigure as a consequence of assembly with the biasing component so as to provide a pivot line or a zone of

pivot lines between the jaws about which articulation to and from the clamping condition can occur (e. g. in the nature of a knuckle or the like female/male engagement).

Preferably said biasing component is adapted to hold the jaws together.

Preferably said biasing component is a spring in the form of a C, U, W or like shaped member that holds the jaws together on the distorted or redeployed link of said moulded component.

Preferably said jaws include an integral extension thereof to the other side of the pivot and/or flexure axis (axes) or zone to be provided by the link of said moulded component, such extensions when pressed towards each other (preferably) having the effect of opening the jaws against the bias.

Preferably said clamping device is part of a garment hanger.

Preferably said garment hanger includes a spaced pair of jaws, one of each pair of jaws being fixed relative to the arms of the hanger disposed to either side of its rail or other engaging region, whilst the other jaw of each pair is in the assembled product relatively moveable to its complementary fixed jaw.

DETAILED DESCRIPTION OF THE INVENTION In the preferred form of the present invention a clamp device which is a double clamp garment hanger will be described. It should be appreciated however that this is just one of several different types of product that can be manufactured using the techniques of the present invention and/or moulded components of the present invention. Others include pegs, clamps, etc.

The present invention recognises that a great number of injection moulded garment hangers in the past have been in a material of a flexible nature (e. g. polypropylene) thereby necessitating greater cross-sectional areas to confer some degree of rigidity to the structure where it is needed.

The present invention offers a capability where a plastics material less flexible than, for example, polyproperlene may be utilised. One such material is that of solid polystyrene.

The hanger of Figures 1 and 2 is an assembly of three components only. These components are the moulded component 1 and two metal (e. g. spring steel) springs 2 (see Figure 9).

The moulded component is capable of being moulded in groups in a mould assembly but for simplicity Figure 10 shows a single mould cavity showing how there can be a cavity to define the hanger region proper (e. g. similar to that of New Zealand Patent No. 227834) plus the arms disposed therefrom and how sliding blocks (whether single components or assemblies) can be utilised to both form and then clear the jaw pairs and their links to be described in more detail hereafter.

In the arrangement shown in the figures preferably the injection of the plastics material into the cavity is such that it enters at 3 (see Figure 2). This material when so injected provides the hanger supporting hook 4 and the arms 5 supported therefrom. Thereafter the material flows outwardly to define the fixed jaws 6 with their jaw proper regions 7, a fulcrum region 8 and an extension 9 thereof beyond the fulcrum region 8. The material (if of a suitable melt flow index for the bridging link at the injection pressures) also flows through the bridging link depicted in the figures. In this respect, see the region 10 in Figure 8 and 6.

The material by passing through the passageway that provides the bridge or link 10 then defines the outer jaw component 11 which, as with the fixed jaw 8, has a jaw proper region 12, a fulcrum region 13 and an extension 14. A small flashing may eventuate.

The extension 9 and 14 in the assembled clamp at each end of the arm of the garment hanger is to allow squeezing together of those regions, in use of the assembled hanger, against the bias of the spring (which acts directly and/or indirectly through the fulcrum region and onto

each of the jaw members 7 and 12) thereby to separate the jaw regions proper 7 and 12 from whence they can be returned under the bias to a clamping condition.

Figure 6 shows the jaws as they are ex-mould during any carriage thereof from the mould (by suction pick up or otherwise) and indexing thereof to a jig or other arrangement where a work person or robot can then insert the spring in each pair of jaws to result in the holding together (yet preferably apart to the extent of at least the reconfigured link) of the jaws in the manner best depicted in Figure 7. In this respect it can be seen that the spring 2 in Figure 7 passes through openings of each jaw such that the arm thereof locates on the jaw proper away from what might be considered the fulcrum region.

In the preferred form of the present invention the link or bridge 10 has certain characteristics. One characteristic is that there is preferably the indexing during removal of the moulded component from the mould. Preferably also there is sufficient location relative to each other to enable easy jigging of the thus indexed jaw regions for the purpose of spring or other engagement therewith.

As depicted in the drawings the link includes an arcuate region over which extends another region such that under pressure in use after spring association therewith, the other region, as a male member, is received in the arcuate region, as a female member. This may occur where the elastic limits of the material have been exceeded or there is sufficient spring and/or other pressure to assume that condition, and thereby provide a knuckle type joint line.

In some forms of the present invention however the link or bridge has sufficient flexure such that over at least initial periods of use there is no such exceeding of the elastic limit of the material, and thus partial or total rupture. It does not matter however if there is rupture since there is the male into female location if there is not otherwise a sufficient reproducibility in the holding of the jaws by the spring itself.

In the preferred form of the present invention however the spring co-acts with the link to provide the reproducibility of locus of clamping/unclamping movement desired for the jaw pairs.

Persons skilled in the art will appreciate how the region I-I when assembled but squeezed outwardly to that condition against the bias (when present in use) provides for no mechanical advantage that will affect the clamping effect, and thus release garments, owing to mutual hanger to hanger abutment whilst on a support rail.

Figures I IA onwards deal with preferred moulding and jigging apparatus although preferably robotics are used for both moulding removal and for jigging placement etc. for the purpose of the application of the biasing member.

Figures 11 B and 12 show the complementary moulding components, ie; no moulding being shown whilst Figures 11A and 13 show a moulding still being retained in part of the assembly.

In Figure 11B there is a cavity 15 for each moulding including part of the jaw pairs. The remainder of the jaw pairs is defined or is definable by the outwardly and inwardly slidable tooling components 16 carried by the assembly of which the cavity 15 forms part and the mating cavity 17 of the other assembly shown in Figure 12.

Shown in the assembly of Figure 11B are passageway openings 18 each adapted to receive a camming, finger or the like member 19 such that as the assemblies of Figures 11B and 12 are brought together there is an inward sliding towards each other and over part of the cavity between the remainder of the assemblies of each part 16 thereby to define the final mould cavity when the tooling is fully closed for a plastics injection. The same fingers 19 when the two assemblies are being separated will have the effect of moving the parts 16 outwardly to the condition as shown in Figure 11B at the conclusion of a moulding step such that the then complete mouldings 20 as shown in at least Figure 1 lA can then be pushed out, lifted out or the like. In some forms they are dropped to a bin for subsequent assembly whilst in other forms they can be robotically removed from the respective cavity 15 under the action, for example, of a robot that either grips the moulding or uplifts or takes it reliant upon a vacuum uplift.

Any appropriate ejection process for the components 20 from a cavity 15 can be used such as direct air ejection or a push out procedure reliant on hydraulics or pneumatics or a solenoid.

Indeed some mechanical drive for such purpose can also be provided.

Persons skilled in the art will appreciate from the drawings other ways in which the moulding can be provided.

Figures 14 onwards show a simple jigging arrangement whereby a moulding 21 is located with its jaw defining members received within a cavity 22 of an inwardly moveable arrangement 23 under the action of a ram assembly 24 thereafter to have biasing members 25 pushed downwardly on to the respective ends of the moulding under the action of a ram assembly 26.

Any alternative procedure for such an approach can be utilised but the preferment is some form that reproducibly supports the jaws relative to each other reliant upon the taking of the link between the jaw components to a stable pivot defining condition in order to receive the biasing member 25 destined therefor.

Persons skilled in the art will appreciate how robotic variations of such apparatus can involve jigging in seeming open space (ie; the robot in part being the jigging, etc. ) or jigging at a station to which robotics or the like bring the component 21 and from thence take the assembled hanger. Similar procedures attach to other variations of the present invention.

Persons skilled in the art will appreciate how the present invention provides the prospect of garment hangers, pegs, clamps, etc. that will find wide spread acceptance.
