  • BRIEF DESCRIPTION OF THE DRAWINGS
  • [0015]
    These and other features, aspects and benefits of the present invention will be apparent to those skilled in the art with reference to the following detailed description and accompanying figures, where like reference numerals refer to like features across the several views, and wherein;
  • [0016]
    FIG. 1 illustrates a front elevation view of a hanger according to an exemplary embodiment of the present invention;
  • [0017]
    FIG. 2 illustrates a cross-sectional view of the hanger of FIG. 1, taken along section line 2-2;
  • [0018]
    FIG. 3 illustrates a perspective view of an exemplary embodiment of the garment hanger of FIG. 1; and
  • [0019]
    FIG. 4 illustrates a front elevation view of a hanger according to an alternate embodiment of the present invention.
  • DETAILED DESCRIPTION OF THE INVENTION
  • [0020]
    Referring now in detail to the drawings, and particularly the hanger construction as shown in FIG. 1, there is illustrated a front elevation view of a molded plastic garment hanger, generally 10, having a central hook portion 12, which is upstanding from the hanger body 14. Body 12 includes a pair of coplanar and oppositely directed arms 16 and 18 for suspending one or more garments, as is well known in industry. Arms 16, 18 may also extend downwardly from body 12.
  • [0021]
    In order to provide reinforcement for the hook portion 12, a suitable gusset or flange 20 may be molded into the hanger proximate the juncture between base of the hook portion 12 and the hanger body 14. This will impart an enhanced degree of strength against bending of the hook portion in the plane of the body 14 under the weight of a supported garment. In the exemplary embodiment of FIG. 1, hook portion 12 is formed of metal that is joined to the body 12 at flange 20. In other embodiments, the hook portion 12 may be formed of plastic and/or integrally molded with the body 12, notwithstanding the presence of absence of a flange 20.
  • [0022]
    Either or both of arms 16, 18 of hanger 10 may incorporate a non-slip plastic insert 22, 24. The molded body member has ‘u’-section arms, illustrated in cross-section in FIG. 2, which provide structural strength for the hanger and support for the garment. The ‘u’ cross-section of the exemplary embodiment has an upwardly facing surface 30, which is arcuate, and laterally facing surfaces 32, 34. Other cross-sectional beam geometries, including ‘I’, ‘square-m’, and ‘C’, among others known in the art, may be substituted without departing from the scope of the present invention. Particularly contemplated is a variation wherein the radius at the top of the cross-section is less pronounced, providing a substantially flat upwardly facing surface with only minimal, negligible, or no rounding at the intersection of upwardly facing surface 30 and laterally facing surfaces 32, 34.
  • [0023]
    Provided along either or both lateral edges 40, 42, of the upwardly facing surface 30 and adjacent the intersection of the laterally facing surfaces 32, 34, are a plurality of locking cells 36. In the exemplary embodiment, locking cells 36 are in the form of concave recesses. Alternately or additionally, locking cells 36 may be formed as other localized surface discontinuity, including but not limited to recesses or depressions. In conjunction with the generally contiguous garment-supporting surface 38 on an upwardly facing surface 30, locking cells 36 improve the frictional interface between the hanger and the garment to be hung from it without forming sharp localized deformations in the hung garment, which is undesirable.
  • [0024]
    As illustrated in FIG. 2, the insert 22 is formed in an upwardly facing surface 30 of the arm 16 to provide a non-slip gripping surface for hanger 10. The non-slip insert 22 is embedded within the outwardly extending arm 16, but may alternately be formed on top of the arm 16.
  • [0025]
    Referring now to FIG. 4, with like reference numerals referring to like structures, it will be appreciated by those skilled in the art that the non-slip insert 22 described herein can be applied to a horizontal bar which may be provided below arms 16, 18 to support trousers or other garments, for example. According to an alternate embodiment of the present invention, a hanger, generally 10 a, has a horizontal bar 50 beneath arms 16, 18. Horizontal bar 50 has a non-slip insert 22, having locking cell 36, generally as described above with respect to arms 16, 18. It will be appreciated that a non-slip insert 22 may be provided on a horizontal bar 50 irrespective of the arms 16, 18. It will further be appreciated that the non-slip gripping surface described is applicable to the arm 16, 18, or to a horizontal bar 50, themselves, without a non-slip insert 22 on or embedded in it.
  • [0026]
    In the exemplary embodiment, the non-slip surface extends substantially to the distal end of each arm 16, 18, including around any downward curvature which may be provided at the distal ends. For the sake of illustration, hanger 10 is a molded plastic hanger, and the non-slip plastic inserts 22, 24 are formed in a co-extrusion process. The bond between the insert 22 and the arms 16, 18 may be a mechanical bond, a molded plastic bond, a fused bond or a combination thereof as desired. The factors which determine the type of bond include the chemical compatibility of the plastics involved, the melting and fusing temperatures of the respective plastics involved, the temperatures at which the plastic is injected into the respective mold cavities, the temperature at which the cavity is maintained, and the respective dwell time between the injection of the first plastic, and the removal of the mold insert and the injection of the second plastic.
  • [0027]
    By adjusting the parameters of the process, one may achieve a mechanical bond, a plastic molded bond, or a wholly fused bond including the surface layers of the plastics being intermixed with each other. In still another embodiment, distortion of the hanger mechanical interlocks as the second hot melt of plastic material flows into the insert produces a bond which is the combination of mechanical interlocking and controlled thermal deformation. This combination form of bonding is particularly advantageous for products, including but not limited to hangers having shoulder inserts, which will be subject to tensile and shear forces as well as compressive forces to ensure superior integrity between the two plastic materials being bonded, particularly in instances with materials having lower levels of chemical synergy.
  • [0028]
    The plastic materials which can be employed with the molding operation in order to produce the inventive composite molded plastic hanger may include, but are not limited to, plastic materials such as polystyrene, SAN, ABS, PPO, nylon, polypropylene (PP), polyethylene, PET, polycarbonates (PC), acrylics, K resin, and polyvinyl chloride (PVC) among others, each being provided with specific coloration in conformance with the specific demands of the customer. When it is desired to mold composite hangers with the non-slip inserts, polypropylene and polyethylene primary materials may be combined with ethylene vinyl acetate (EVA), low density polyethylene, or thermoplastic elastomers for the non-slip portion. Alternately, if polystyrene, ABS or SAN primary materials are desired, they may be combined with ethylene vinyl acetate, PVC, thermoplastic elastomers or thermoplastic rubbers. Other materials suitable for the primary body construction such as PVC, PC, PMMA or a mixture of a polystyrene with one of the foregoing primary materials may be used with EVA, PVC, thermoplastic elastomers or thermoplastic rubbers and the non-slip insert material.
  • [0029]
    In one preferred embodiment, styrene or polypropylene is used as the primary material with a softer material (such as a thermoplastic rubber including, but not limited to, KRATON) used for the insert. In another embodiment a harder material can used as the insert including, but not limited to, polyethylene with a propylene membrane.
  • [0030]
    More particularly, when a chemical bond is desired, it is preferable to use styrene as the primary material or polypropylene as the primary material with EVA/PP mix as insert material. When a chemical and mechanical bond is desired, it is preferable to use styrene as the primary material with styrene rubber as insert material. When a mechanical bond is desired, it is preferable to use polypropylene main as the primary material with polyethylene as insert material.
  • [0031]
    In a particularly preferred embodiment of the present invention, a combination of mechanical interlocking and controlled thermal deformation bonds the first and second plastic materials. The mechanical bonding is accomplished by a series of interlocking buttonhole joints. Commercially available equipment with specific adaptations may be used to mold the composite hanger of the present invention.
  • [0032]
    The primary material contemplated in an exemplary embodiment is a combination of Dow styrene grades 693 and 478. The secondary material is a D grade material available from Shell Oils sold under the trade name of KRATON. The melt temperature of the KRATON is about 600degrees F., plus or minus 50 degrees F.
  • [0033]
    From the foregoing illustrations it is readily apparent that the present invention includes an extremely simple garment hanger construction, preferably produced in a coinjection mold through a simple two step process which requires a minimum amount of effort and expenditure, while being versatile in its applications due to the specific structural aspects of the members. No costly hand labor would be required to affix non-slip strips to the shoulders of the hangers. All is accomplished in a single molding operation.
  • [0034]
    Shown and described herein are what are merely exemplary embodiments of the present invention. These descriptions are meant to be illustrative, and not limiting, on the scope of the present invention. Those skilled in the art will appreciate that various modifications and changes in form or detail can readily be made without departing from the spirit or scope of the invention. It is therefore intended that the invention not be limited to the exact form and detail herein shown and described nor to anything less than the whole of the invention as defined by the appended claims.
