1. Field of the Invention
In general, the present invention relates to manufacturing techniques used in the fabrication of toy figures. More particularly, the present invention relates to techniques used to combine fabric construction materials with synthetic elastomeric construction materials to produce figures that embody different tactile characteristics.
2. Prior Art Description
In the toy industry, “plush toys” is the name used to describe toys with a fabric-based construction. Such toys include stuffed animals, dolls and the like. Traditionally plush toys are made by sewing together a fabric shell from some type of material, such as cotton or synthetic fur. The fabric shell defines the external shape of the toy. The fabric shell is then stuffed with polyester fibers of some similar type of stuffing material. Hard objects, such as button eyes, can then be either sewn or glued to the exterior of the fabric shell.
Throughout the long history of plush toys, there have many occasions where toy manufacturers have attempted to make toy figures that have both soft plush features and hard non-plush features. For instance, there are many dolls that have hard porcelain heads and hands, but the remainder of the doll is made with traditional plush fabric material. In order to join hard components, such as a doll head to a plush fabric body, the hard component is typically made with a grooved base. The fabric material of the plush section is passed around the grooved base and tightened with thread. The fabric material tightens within the groove, therein creating a mechanical interconnection between the plush section of the toy and the non-plush sections.
As the materials of toys evolved, many toys began to be manufactured from different types of plastic, rather than fabric. For instance, many dolls have bodies made from hard plastic. The heads of the dolls, however, are often molded from a softer more pliable plastic. Although plastic is used, the type of connections between the two different types of plastic parts remains traditional. Typically, the toy part made from the harder plastic is molded with a grooved base. The toy part made from the softer plastic is made with an opening that can be stretched around the grooved base. When the opening of softer plastic contracts into the groove of the harder plastic, a mechanical interconnection is created that joins the plastic sections.
In the toy industry, elastomeric gels are becoming increasingly popular. Elastomeric gels are triblock copolymer plastics that have been mixed with a plasticizing oil to form an elastic gel. Elastomeric gels embody a high degree of elasticity and a high resistance to tearing that make such gels useful in toy manufacturing. There are currently several elastomeric gels that are commercially available. One of the earliest elastomeric gels is exemplified by U.S. Pat. No. 4,369,284 to Chen, entitled Thermoplastic Elastomer Gelatinous Compositions.
Elastomeric gels are typically molded into toys such as balls and flying discs using traditional injection molding techniques. The use of injection molding techniques prohibits elastomeric gels from being molded directly onto a non-plastic plush form. In industry, elastomeric gels have been applied to fabric objects, such as socks, in order to provide cushioning. Consider U.S. Pat. No. 6,406,499 to Kania, entitled Gel And Cushioning Devices. However, in such applications the fabric body is dipped into a vat of molten elastomeric gel material. The elastomeric gel material is then given time to cure upon the fabric body.
A problem occurs when a toy manufacturer desires to create a figure that is part plush and part elastomeric gel. Traditional mechanical attachment techniques do not work. Since the elastomeric gel is so elastic, it easily pulls away from any sort of grooved connection base it may be stretched across. Furthermore, elastomeric gels cannot be molded onto plush toys, nor can elements of a plush toy figure be created by molten dipping. The only solution to date has been to glue elastomeric gel material to fabric using traditional acrylic based glues. However, since the traditional acrylic glues used harden when they cure, the glues quickly peel away from the elastomeric gel as the elastomeric gel stretches and deforms under the hardened glue. The component of the toy made from the elastomeric gel, therefore, quickly peels away from the remainder of the toy, where it can become a choking hazard.
A need therefore exists for an improved technique for joining elastomeric gels to the fabric shell of an otherwise plush toy. This need is met by the present invention as is described and claimed below.
The present invention is a toy figure assembly and its method of manufacture. The toy figure has a body structure with an exposed exterior. The exposed exterior of the figure includes at least one first section of fabric material and at least one second section of elastomeric gel material that are joined together along at least one common seam. The common seam can be closed using adhesive, heat bonding or sewing. The sections of the toy figure defined by fabric material are filled with dry fill. The sections of the toy figure defined by elastomeric gel material can be filled with either dry fill or a fluid fill, such as liquid or air.
By forming a toy figure from both fabric material and elastomeric gel, a toy figure is obtained that has external areas having contrasting tactile characteristics, thereby increasing the play value of the toy figure.
For a better understanding of the present invention, reference is made to the following description of exemplary embodiments thereof, considered in conjunction with the accompanying drawings, in which:
There are countless varieties of plush toys. The present invention is described using one exemplary configuration of a plush toy. This configuration is intended to be merely exemplary of any plush toy configuration and should not be considered to limit the application of the present invention to other plush toy configurations.

The thermoset glue 34 is made of a triblock copolymer. The elastomeric gel material 30 is made from the same family of materials. Accordingly, the elastomeric material 30 readily bonds with the thermoset glue 34. Furthermore, since the thermoset glue 34 is applied in a heated molten form, the thermoset glue 34 momentarily melts the elastomeric gel material 30 it contacts, thereby creating a direct heat bond between the elastomeric gel material 30 and the thermoset glue 34.
The thermoset glue 34 is made primarily from triblock copolymers mixed with resin and a plasticizer. The thermoset glue 34 therefore is highly flexible and exhibits a resistance to tearing comparable to that of the elastomeric gel material 30. The result is that the common seam 26 is strongly bonded to both the elastomeric gel material 30 and the fabric material 32. The thermoset glue 34 will also bend and twist as the elastomeric gel material 30 is stretched, without pulling away from either the elastomeric gel material 30 or the fabric material 32.

The plush construction 56 is not completely filled with traditional fill material. Rather, the plush construction 56 is made to be at least partially hollow. In this manner, the plush construction 56 is partially hollow and a substantial portion of the sealed sack 54 of elastomeric gel can pass into the plush construction 56. The plush construction 56 has an edge that contacts the elastomeric subassembly 52 along one or more seam lines 58. On each of the seam lines 58, the fabric material of the plush construction 56 is attached to the elastomeric material of the sealed sack 54 using one of the interconnection techniques previously described.

The embodiments of the present invention illustrate a new toy figure construction. The toy figure has external portions that are made of traditional plush construction and other portions that are made from elastomeric gel. The fill material under the elastomeric gel can also be different from the fill under the plush construction. The toy figure therefore will have external portions that vary greatly in tactile characteristics.
It will be understood that the embodiments illustrated are merely exemplary and that a person skilled in the art can make alternate embodiments without departing from the principals of the invention. The toy figure can take any shape. It can be a person, an animal or an inanimate object. The shape of the toy figure is a matter of design choice. What is important is that elastomeric material and fabric material are both used to create the toy figure. The elastomeric material is not separate from the plush construction, but rather the elastomeric material and the fabric material are joined together along common seams and integrate to form a toy figure with unique tactile features. Consequently, variations, modifications and alternate embodiments of the illustrated embodiments are intended to be covered by the scope of the claims as defined below.
