Abstract
A wig clip having a set of comb teeth movable into and out of engagement with a clamping member on a frame is provided with a layer of fusible solid material on the frame in a quantity sufficient to enable the wig clip to be secured to the net material of a wig base by the application of heat to the layer of solid material. The application of heat causes the solid material to melt so that, when the wig clip is brought into contact with the net material, the fusible material flows through apertures of the net material, and then resolidifies, the wig clip is securely attached to the net material. The preferred fusible solid material is ethylene-vinyl acetate copolymer.
Claims
1. A wig clip comprising a frame, a set of comb teeth connected to said frame and movable into and out of engagement with a clamping member on said frame, said clamping member having a clamping surface facing in a first direction, and a layer of solid material attached to said frame, said layer of solid material being fusible upon the application of heat, and located on a side of said frame facing in a direction opposite said first direction, said solid material being present on said frame in a quantity sufficient to enable the wig clip to be secured to the net material of a wig base by the application of heat to said layer of solid material to cause the solid fusible material to melt, discontinuing the application of heat, bringing the wig clip into contact with the net material of the wig base, and allowing a portion of said solid material to flow through apertures of said net material, and allowing said fusible material to resolidify, thereby securely attaching said wig clip to said net material.
2. A wig clip according to claim 1, wherein said layer of solid material is an ethylene-vinyl acetate copolymer.
3. A wig clip comprising a frame having a cross-member, a pair of legs spaced from each other and extending in a first direction from the cross-member, a clamping member connected to said legs and extending from one of said legs to the other and spaced from said cross-member, and a set of comb teeth connected to the cross-member of the frame and extending past the clamping member, said comb teeth being movable into and out of engagement with the clamping member of said frame on one side of the frame, wherein said frame includes an area on each of said legs to which a layer of solid material is attached, said layer of solid material being fusible upon the application of heat, and located on a side of said frame opposite said one side of frame, and in a quantity sufficient to enable the wig clip to be secured to the net material of a wig base by the application of heat to said layer of solid material to cause the solid fusible material to melt, discontinuing the application of heat, bringing the wig clip into contact with the net material of the wig base, and allowing a portion of said solid material to flow through apertures of said net material, and allowing said fusible material to resolidify, thereby securely attaching said wig clip to said net material.
4. A wig clip according to claim 3, wherein said layer of solid material is an ethylene-vinyl acetate copolymer.
5. A wig base comprising a net material adapted to fit over the cranial portion of a human head and having an inside surface and an outside surface, said wig base including at least one wig clip, each said wig clip comprising a frame located on the inside surface of the wig base, said frame having a cross-member, a pair of legs spaced from each other and extending in a first direction from the cross-member, a clamping member connected to said legs and extending from one of said legs to the other and spaced from said cross-member, and a set of comb teeth connected to the cross-member of the frame and extending past the clamping member, said comb teeth being movable into and out of engagement with the clamping member of said frame on one side of the frame, wherein said frame includes an area on each of said legs to which a layer of fusible solid material is attached, said areas being located on a side of said frame opposite said one side of the frame, said layer of solid material including first and second portions respectively on the inside and outside surfaces of the wig base, and connecting portions extending through apertures of the net material and connecting said first and second portions to each other, thereby securely attaching said wig clip to said net material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0015] As shown in
[0016] The frame, including the legs, and the cross member is preferably composed of a metal, a synthetic resin, or another material having spring properties. The clamping member 18 is connected to the legs 16 and 18 in such a way that the clamping member is under tension while the cross-member is under longitudinal compression, or, alternatively, so that the clamping member is under longitudinal compression while the cross-member is under tension. As a result, the wig clip can be manually toggled between two stable conditions, one in which the comb teeth 20 are in contact with the clamping member 18 and pressing against the clamping member, and the other, in which the comb teeth are spaced from the clamping member. The comb teeth can be moved to spaced relationship with the clamping member before the wig clip engaged with a wearer's natural hair, and then toggled into the other stable condition, thereby clamping the wearer's natural hair between the comb teeth and the clamping member. The tension and compression in the cross-member and the clamping member can be achieved by applying tension or compression to the cross-member or to the clamping member when securing the clamping member to the legs by means of rivets. If the clamping member and cross member are unitary, a similar result can be achieved by applying tension or compression in the process of forming the unit.
[0017] The clamping member 18 is preferably covered by an elastomeric sleeve of natural or synthetic rubber, to improve frictional contact between the wig clip and the wearer's natural hair.
[0018] The clamping surface of the clamping member 18 engageable by the comb teeth faces the comb teeth in a first direction. As shown in
[0019] The fusible solid material can be selected from a variety of hot-melt adhesives, including EVA (ethylene-vinyl acetate copolymers), acrylic, polyolefin, polyurethane, polyamide, and natural rubber. For this application EVA is preferred, and suitable EVA hot-melt adhesives include ELVAX 150 ethylene-vinyl acetate copolymer, available from E. I. duPont de Nemours and Company, Inc., Chestnut Run Plaza, Bldg. 730, 974 Centre Road, Wilmington, Del., 19805 USA, and RELENE EVA ethylene-vinyl acetate copolymer, available from Reliance Industries Limited, Reliance corporate Park, Block 8A, Thane Belapur Road, Ghansoli, Navi Mumbai 400701, India. EVA typically melts at a temperature of about 63 C.
[0020] As shown in
[0021] The heating element can be in the form of an electrically heated element that is brought into direct contact with the fusible material, or alternatively a heat gun or similar device that directs a stream of hot air toward the fusible layers.
[0022] After the side of the wig clip frame on which the fusible layers 22 and 24 are located is brought into contact with the net material of a wig base, and a part of the fusible material is allowed to flow through the apertures of the net material, the fusible material resolidifies and portions of the fusible material on both sides of the net are connected to each other by elements of fusible material extending through the apertures of the net. As shown in
[0023] A typical wig base net material melts at a temperature of approximately 82 C., not far above the melting temperature of the EVA hot melt adhesive. For this reason, the step of discontinuing the application of heat, is preferably carried out and discontinued before bringing the wig clip into contact with the net material of the wig base. However, in the case of a higher melting wig base material, the heating device can be operated while the wig clip is in contact with the base material.
[0024]
[0025] One of the advantages of the use of fusible material to attach wig clips to the wig base is that no sewing or other time-consuming steps are required to attach the clips to the wig base. The attachment can be carried out in a very short time, making it possible to customize the number, arrangement and positions of the wig clips to accommodate the needs of a particular individual wearer.
