Abstract
An inanimate figure having soft, resiliently deformable skin defining a body and limbs, at least one of the limbs housing an articulating limb structure comprising at least two substantially rigid limb frame members joined by at least one articulating joint disposed therebetween.
Description




FIELD OF THE INVENTION




The present invention generally relates to toy figures or dolls and more particularly to toy figures having deformable skin and one or more articulating limbs comprising rigid structural members which articulate with respect to each other.




BACKGROUND OF THE INVENTION




A variety of dolls and action figures are known which are made by molding a soft polyvinyl chloride resin or other soft plastic material. It is considered desirable to provide such toy figures with an exterior texture that simulates the feel of skin. It is also considered desirable to provide flexible limbs to permit a child to manipulate the toy figure creatively.




U.S. Pat. No. 3,699,714 discloses a doll having a foam body and limbs with a flexible wire housed within the limbs to make them bendable into various positions.




U.S. Pat. No. 2,606,398 describes a stuffed doll formed by coating a form with latex coagulant, dipping the coated form in a vulcanizable rubbery material, drying the material and vulcanizing the doll. The doll is then removed from the form and filled with textile fibers, rags or similar yielding materials.




U.S. Pat. No. 4,055,020 describes a rotationally molded doll torso which is filled with pressurized air. The torso is provided with joints for rotatingly attaching the head and limbs.




U.S. Pat. No. 4,169,336 describes a doll having stretchable arms and legs which can be drawn into various configurations. The doll has an external skin of elastic film and is filled with a viscous liquid such as corn syrup.




The prior art toy figures and dolls having soft resilient skin and flexible limbs do not provide realistic ranges of articulation for the limbs. It would be desirable to provide a toy figure with a skin layer that is soft and resiliently deformable and limbs with rigid limb member that act as “bones” that are capable of articulating relative to one another in a realistic manner.




SUMMARY OF THE INVENTION




The present invention provides a toy figure or doll with articulating limbs comprising rigid limb members connected by articulating joints. The toy figures of the present invention preferably have a hollow body made of a resiliently deformable, soft skin layer and are preferably stuffed with a soft fill material to further simulate a “live” feel.




In a preferred embodiment, the skin of the body and limbs of a toy figure of the invention are cast separately and assembled. The limbs are preferably joined to the body by e.g., connector joints, although it is also contemplated that the articulating limbs may be completely enclosed within the limbs, with the limbs and body of the toy figure being joined by adhesive or other means. Alternatively, the toy figure may be molded as a single piece and the articulating limbs inserted through openings at the extremities of the limbs which are then patched, for example by an injection molded piece, optionally with the distal ends of the articulating limb structures being glued to the inside surface of the injection molded patches.




The body and limbs of the toy figure or doll are cast by conventional rotational molding or slush molding as is well known in the art. The cavities of the body and limbs are preferably stuffed with polyester fiber, gel or other soft, deformable material.




In particularly preferred embodiments, the toy figure may be sized up to 2-3 feet or more in length or more with limbs up to 18 inches or more in length. Toy figures of this size are sometimes referred to as “my size” figures, referring to their size relative to a child.

DETAILED DESCRIPTION OF THE INVENTION




The toy figures of the present invention preferably comprise separately molded torsos and limbs which are stuffed with a fill material, fitted with one or more articulating limb structures and connected during assembly. The terms “limbs” as used herein is meant to encompass arms, legs, heads, tails or other components that may be molded separately from the torso and connected to the torso during assembly.




Referring to

FIG. 1

, a toy

FIG. 10

includes a torso


12


truncated at the head/neck attachment area


13


, left shoulder attachment area


14


, right shoulder attachment area


16


, left hip attachment area


18


and right hip attachment area


20


. The toy figure includes a head and neck


22


, left arm


24


, right arm


26


, left leg


28


and right leg


30


, each having corresponding attachment areas. These limbs are attached to the torso at the respective attachment areas by mushroom joints


32


, as more fully described below, which permit rotation of the limb relative to the body.




In a presently preferred embodiment of the invention, the limb attachment areas of the torso and the corresponding attachment areas of the limbs, are sized and shaped to mate complementarily with each other and facilitate articulation at the point of connection, if desired. The two respective attachment areas may be generally planar (e.g.,


14


,


16


) where the desired articulating movement is only rotation, although preferably, where the connection used to join the limb to the torso comprises a pivot joint, ball joint or the like, the torso is provided with a recessed or cup-shaped limb attachment area (e.g., as depicted in

FIG. 7

) to receive the corresponding limb.




To facilitate articulation of, for example, the knees and elbows of a toy figure, the external skin of the limbs optionally may be molded to provide accordion-like pleats (not shown) which fold to accommodate excess skin as the structural members articulate between their fully extended and contracted positions. The pleats may be provided on the backside or frontside of the limb or both. The pleats may be provided on limbs which have or do not have articulating structural members inside. The pleats also provide a convenient way to store a toy figure of the present invention by folding the limbs to lie adjacent to the body so as to be relatively compact during storage. This feature is also advantageous for shipping.




The skin of the torso and limbs may be formed from any suitable resiliently deformable vinyl resin material including pliable polyvinyl chloride compositions known in the art. The skin is preferably molded by rotational casting or slush molding methods. The applicants' presently preferred polymer formulations comprise about 35%-45% polyvinyl chloride; about 50%-60% di(C


7


-C


12


alkyl)phthalate, wherein the alkyl moieties are linear or branched and are the same or different; about 1%-3% epoxidized soybean oil (as a high-temperature resistance agent); about 1%-3% of a liquid calcium and zinc organic complex stabilizer (as a heater stabilizer) and up to 1% pigment. The polymer compositions may optionally contain about 0.5%-1% plasticizer such as Kodaflex TXIB (trimethyl pentamediol diisobutyrate), available from Eastman Chemical Co., (CAS No. 68-46-50-0), as a hardener to adjust the rigidness of the skin as needed. Among the dialkylphthalate compounds which may be used are diisoheptylphthalate, diisooctylphthalate, diisononylphthalate and the like. Diisononylphftalate is most preferred. Diisononylphthalate is commercially available under the tradename “Jayflex” from Exxon Chemical Company. Such polymer formulations enable rotational casting or slush molding of molded torso and limb pieces that may be up to about 24 inches to 36 inches in length or more and have a finely textured and resiliently deformable skin of uniform thickness throughout. Molded pieces of such a large size and with uniform skin thickness are not attainable with conventional polymer formulations. The presently preferred polymer formulation for use in forming the skin of the toy figures of the present invention comprises about 40% polyvinyl chloride; about 55% diisononylphthalate; about 2% epoxidized soybean oil; about 2% calcium/zinc (as a heat stabilizer); about 1% pigment; and optionally about 0.5%-1% plasticizer.




The skin of the torso and limbs may be molded by adding a predetermined amount of skin-forming polymer into the cavity of the mold and rotating the mold to ensure uniform coverage of the polymer on the inner surface of the mold. As is known, conventional rotational casting involves rotating the mold around a first axis while it is simultaneously being moved orbitally around a second axis which is generally at a right angle to the first. In rotational casting or slush molding, the mold is heated to cause the skin layer to form on the inner surface of the mold. Alternatively, the mold may be entirely filled with the skin-forming polymer and heated to cause the skin layer to form on the inner surface of the mold, with the remaining liquid polymer being decanted after the molded skin having the desired thickness is formed.




In a presently preferred method for molding torso and limb components, the resin composition is made by mixing 55 parts by weight diisononylphthalate, 40 parts by weight polyvinyl chloride powder and optionally 0.5 to 1.0 part by weight Kodaflex™ TX


1


B plasticizer (CAS No. 68-46-50-0) with constant stirring. After these ingredients are thoroughly mixed, 2 parts by weight epoxidized soybean oil, 2 parts by weight Ca/Zn heat stabilizer (Brainstab CZ-101, Brain Resources Enterprises Company Limited, Kowloon, Hong Kong) and 1 part by weight pigment is added with constant mixing. The ingredients are blended for three hours, followed by degassing in a vacuum chamber for between 10 and 30 minutes to remove air bubbles from the blending process.




The present invention may be practiced, for example, in constructing a torso about 10 inches in length and about 15 inches in circumference at its widest point by blending and degassing a resin composition as described and then injecting it into a pumping device connected as is known in the art to a selected slush mold. The slush mold is fully filled and the filled mold is then dipped into a 200° C. liquid wax pool for 1 {fraction (1/2 )}minutes to form a raw skin. The mold is then removed and the excess resin composition from the first heating step is poured off, leaving the raw skin formed on the inside walls of the slush mold. The raw skin from the first heating step is then “matured” by re-dipping the slush-mold for a second treatment at 200° C. for an additional 2 minutes. The mold is then transferred to a running cold water bath for about 4½-5 minutes to separate the matured skin from the inner walls of the slush mold. The matured skin is then removed through the opening of the slush mold, carefully avoiding damage to the skin.




It will be understood that dimensions, quantities of materials, and processing times and temperatures are only illustrative since conventional rotational molding or slush molding concepts can be utilized in combination with the presently preferred polyvinyl chloride/ldiisononylphthalate composition or a variety of conventional polymer formulations for forming articles of various sizes and shapes, with the quantities of materials and processing conditions being readily determined by those skilled in the art for the particular article being formed.




As mentioned above, the torso and limbs of a toy figure of the present invention may desirably be filled with a soft resilient stuffing material. The stuffing material may be made of any resilient material that imparts, in combination with the resiliently deformable skin, a desirable tactile quality to the toy figure. A presently preferred stuffing material is polyester fiber which is made by heating polyester pellets and “pulling” them into fibrous strands as is known in the art. Alternatively, the stuffing material may be a gel or a suitable natural or synthetic fiber or cloth.




The toy figures of the present invention have one or more articulating rigid structures within their limbs. The articulating limbs of the present invention are generally comprised of two or more substantially rigid structural members connected end-to-end or serially with an articulating joint between adjacent structural members. The structural members of the limb may be dimensioned to resemble the bones of the limb.




The articulating joint connecting two structural members may be any suitable type of joint that permits pivoting, rotating and/or swiveling motion between adjacent structural members of the limb. Examples of such articulating joints include pivot joints, clevis joints, ball joints and the like.




The structural members of the limbs and the joints are preferably cast of a suitably rigid material. It is presently preferred to cast the structural members of the limbs and joints by injection molding employing polycarbonate, polyethylene, polypropylene, polystyrene, polyvinyl chloride, acrylonitrile-butadine-styrene or the like. The various joint members may be affixed or adhered to the structural members of the limb or, preferably, may be incorporated into (e.g., cast integrally with) the end of a limb structure as described herein.




The skin of the limbs, whether containing an articulating limb structure or not, may be joined to the torso by connector joints. One type of connector joint is a mushroom joint. The first member of such a connector joint comprises a flange and a rounded or mushroom-shaped head spaced apart from each other by a spacer piece; and the second member of the connector joint comprises a substantially rigid, resilient bushing that is elastically deformable to receive and retain the rounded head of the joint. One joint member is seated within the torso at the limb attachment area and the other joint member is seated within the limb at the corresponding attachment area. The spacer piece of the connector joint member is sized so that the attachment areas of the torso and limb may be brought together in between the flange and bushing surfaces, preferably while allowing rotation of the limb relative to the torso. See, for example,

FIGS. 4 and 5

. Where the limb contains an articulating limb structure, connector joints used to connect the proximal end of a limb to the torso may be a mushroom type joint that optionally comprises a pivot joint or ball joint disposed between the limb structure and torso, as described below. See, for example, FIG.

therein. The lower leg


218


comprises a lower leg frame


220


with a cylindrical upper portion


221


sized to retain (e.g., by adhesive or friction fit) lower leg bushing


222


. Leg bushing


222


comprises a flange


223


and has a tapered bore


224


running longitudinally through the bushing, the bore having a relatively larger diameter at the (upper) flange end to form a “socket” upon which rounded head


210


is seated for articulation. The upper and lower leg frames are connected to each other and to the body by an elastomeric band


214


which is provided at one end with an eyelet


216


for attachment to hook


228


, which hook is configured with two curled ends, one of which receives eyelet


216


of the elastic band and the other of which anchors the band to a rivet


230


inside connector joint


232


as shown in FIG.

) and threading the upper end of band


224


through openings


212


and


208


of the upper leg frame and anchoring eyelet


216


to rivet


230


via hook


228


such that the elastic force exerted by band


214


causes rounded head


210


to be seated in the cup-shaped end of lower leg bushing


222


to form a ball joint connection and causes rounded head


206


to be seated rotatingly on flange


233


of joint


232


. The assembled leg structure is inserted into skin


242


with the connector joint member


232


protruding from opening


244




a,


and articulating leg


200


is connected to torso


246


by pressing the head of connector joint


232


onto bushing


234


retained within the torso


246


in alignment with opening


244

256


divided bilaterally along an axis of the socket. Half-socket


254


further comprises a rounded head


258


spaced apart from half-socket


254


by spacer piece


260


to provide a member of a connector joint.




Ball


250


is attached to upper leg member


262


by screw


264


which extends through bore


251


and into threaded bore


266


of upper leg frame


262


. Ball


250


is articulably retained in the socket formed when the two socket members


254


,


256


are joined edgewise such as by adhesive or snap-fitting. In this embodiment the structural components of the knee joint and lower leg may be similar to a previously described embodiment (e.g., pivot joint, clevis joint, etc.).




The assembled leg is installed in the skin


268


and is attached to the torso


270


by pressing head


258


of the connector joint onto bushing


270


(aligned with the limb attachment area of the torso


272


) as described above with reference to

FIGS. 2 and 3

. The upper leg is thus capable of rotating and pivoting in any direction relative to the body.




With reference to

FIGS. 12 and 13

, a particularly preferred embodiment of a ball joint is shown wherein the ball member of the ball joint carries a flange member to seat it within the torso (without the use of a mushroom joint).




In this embodiment, the ball joint members are formed from acrylonitrile-butadine-styrene and fit together in a snap fit arrangement. Upper leg frame


302


is adapted at its upper end with a socket


304


that has a generally hemispherical shape. Socket


304


terminates at it upper surface in an anular flange


306


having a short collar


307


. The collar


307


has a diameter that is smaller than the diameter of the socket, yet large enough to allow the ball member


310


to be snap-fit into articulating contact with socket


304


. Socket


304


is provided with a plurality of symmetrically spaced apertures


312


which engage the knobs


314


complementarily disposed on ball


310


to reversibly retain the ball joint in one of several predetermined positions when the knobs


314


and apertures


312


are aligned for engagement. It will be appreciated that the lower leg frame (not shown) may be articulably connected to the upper leg frame by a ball joint, pivot joint, clevis joint or the like as described herein with reference to other embodiments of an articulating limb.




The ball member of the ball joint carries a flange


318


having a diameter larger than that of ball


312


. The flange


318


is spaced apart from ball


312


by spacer piece


316


which extends axially from the ball


310


. Flange


318


is sized to firmly anchor the ball member within the torso with the ball


310


and spacer piece


316


extending through the opening


328




a


of the limb attachment area


326


of the torso


322


and into the opening


328




b


of skin


330


.




The flange


318


is adapted with a tab


320


on the side opposite the spacer piece


316

Turning to

FIGS. 14-19

, another embodiment of an articulating limb for a toy figure having a life-like pliable outer skin is shown at


400


. The limb


400


is joined to a body


401


of the toy figure. The limb shown in the figures and described below is generally related to a leg, however, the structural elements of the leg may be easily modified to form an arm or other appendage without deviating from the novel aspects of the present invention. The body includes a pliable skin


404


, and the leg skin


406


. Both the body skin and the leg skin may be formed of any suitable resiliently deformable vinyl resin material and molded as described above. The skin may be further stuffed with a polyester fill to provide a more pliable life-like feel to the skin.




The internal structural components of the articulating limb include a lower leg member


408


and an upper leg member


410


. The lower leg member


408


is pivotally joined to the upper leg member


410


to form a knee joint


420


. The upper leg member


410


is similarly pivotally joined to an annular disk


424


to form a lateral hip joint


418


which allows the limb


400


to be pivoted away from the body


401


. As will be described in more detail below, the annular disc


424


may be joined to a receiving disk


426


mounted within the body


401


. Together, disk


424


and receiving disc


426


form a rotating hip joint


416


. Radial spacers


412


and


414


are placed around the lower and upper leg members respectively to support the outer skin. A linear spacer


422


extends from the lateral hip joint to provide outward support of the skin near the upper portion of the limb.




Radial spacers


412


,


414


are substantially identical, comprising a central hub


428


and an outer annular ring


430


supported from the hub by a plurality of spokes


432


. The central hub includes a bore


436


surrounded by a plurality of narrow radial slots


433


. Each of the lower and upper leg members


408


,


410


include a spacer support area


438


defined by vertically spaced rings


440


of diameter nominally larger than that of the bore


434


through the central hub of the radial spacers


412


,


414


. The spacers are mounted on each of the upper and lower leg members by sliding the members through the bore


434


and forcing the hub over a first support ring so that a support ring engages and supports each side of the hub. Ribs


435


formed on the leg members align with the slots


433


to hold the spacers in place.




As can best be seen in

FIG. 15

, a clevis joint forms joint the knee


420


. A U-shaped clevis piece


442


having a bore


448


extending through both sides thereof is formed at the lower end of the upper leg member


410


, and a mating flat clevis


446


piece having a bore


450


formed therethrough is formed on the upper end of the lower leg member


408


. The flat clevis piece is adapted to be inserted into the slot


444


formed in U-shaped clevis member


442


so that bore


450


aligns with bore


448


, and pin


452


may be inserted therethrough to pivotally connect the lower leg member


408


to the upper leg member


410


. Thus, the lower leg member may pivot freely relative to upper leg member


408


.




The lateral hip joint


418


is formed in a similar manner. A U-shaped clevis is formed on the under side of hip disk


424


and has a bore


458


extending through both sides thereof. A flat clevis piece


456


is formed at the upper end of upper leg member


410


, and has a bore


460


extending therethrough. The flat clevis piece is adapted to be inserted into the slot


455


formed in U-shaped clevis member


454


so that bore


460


aligns with bore


458


, and pin


462


may be inserted therethrough to pivotally connect the upper leg member


410


to the hip disk member


424


. Thus, the upper leg member


410


may pivot freely relative to the rotary hip joint


416


and the body


401


.




The angle through which the upper leg member may pivot relative to the hip disk


424


is limited by a hip extension piece


464


that extends from the flat clevis piece


456


. A mushroom connector


466


is formed at the end of extension piece


464


. Hip spacer


422


comprises an end cap having a mounting bore


468


for receiving the mushroom connector


466


. An outer support surface


470


is configured support the outer skin to provide an outward radial contour to the hip region of the toy figure.




As shown in

FIG. 16

, the assembled structural components of the articulating limb may be inserted into the molded outer skin


406


through an aperture


472


located at the radial hip joint. Aperture


472


is surrounded by an inwardly directed stepped annular ridge


474


. The stepped profile of the ridge can be seen best in the cross sectional view of FIG.


14


. The hip disk


424


includes an outer annular rim


476


which is thicker than the remainder of the disk surface, creating a depressed central region


477


. When the structural components of the limb are inserted into the skin


406


, the annular ridge may be stretched over the annular rim


476


of the hip disk, and once in place, the distal end


479


of the stepped annular ridge is seated within the depressed central region


477


of the disk and the thicker rim portion of the disk is seated under the proximal stepped portion


481


of the stepped ridge.




Turning to

FIG. 17

, a ring fastener


484


is provided to secure the molded skin to the hip disk


424


. Threaded bosses


478


are formed on the recessed surface


477


of hip disk


424


and corresponding inwardly directed screw support flanges


488


are formed on the inner circumference of the ring fastener. Bores formed in the screw support flanges


488


align with the threaded bosses so that screws


490


may be driven through the flanges and into the bosses to attach the ring fastener to the hip disk. Spiny teeth


486


extend from the inner surface of the ring, and are adapted to sink into the molded skin comprising annular ridge


474


when the ring fastener is screwed onto the hip disk, thereby securing the molded skin to the hip disk.




Turning to

FIG. 18

, the body side of the rotary hip joint assembly is shown. The body skin


404


includes an aperture


492


similar to the aperture


472


formed in the molded outer skin of the leg assembly. A stepped annular ridge


494


encircles the aperture and is adapted to receive the annular rim


496


formed around the outer edge of the receiving disk


426


. Annular rim


496


creates a recessed central region


497


of receiving disk


426


. When the receiving disk is inserted within the body skin


404


, the annular ridge


494


may be stretched over the annular rim


496


of the receiving disk. Once in place, the distal step


499


f the stepped annular ridge is seated within the recessed central region


497


of the disk, and the thicker rim portion of the disk is seated against the proximal step


501


of the stepped ridge (see the cross sectional view of FIG.


14


).




A ring fastener


504


is provided to secure the molded body skin to the receiving disk


426


. Threaded bosses


498


are formed on the recessed surface of receiving disk


426


and corresponding inwardly directed screw support flanges


506


are formed on the inner circumference of the ring fastener. Screws


510


may be driven through the flanges and into the bosses to attach the ring fastener


504


to the receiving disk. Spiny teeth


508


extend from the inner surface of the ring and are adapted to sink into molded body skin


404


comprising annular ridge


494


when the ring fastener is screwed onto the receiving disk, thereby securing the molded skin to the hip disk.




The receiving disc


426


includes a central aperture


502


surrounded by inwardly directed flanged stays


500


. As is indicated in

FIG. 19

, the aperture


502


is adapted to receive the mushroom connector


480


that is raised above the surface of the hip disk


424


by the spacer element


482


. The inwardly projecting stays


500


flex outwardly as the mushroom connected is inserted into the central aperture


502


, then once the mushroom connector passes the inwardly projecting stays, the stays collapse behind the connector, securing the limb to the body (see FIG.


14


). The spacer


482


is smaller than the aperture


502


formed between the stays


500


so that the spacer is free to rotate therein while hip disk remains securely attached to the receiving disk, thereby allowing the limb to rotate relative to the body.




While the toy figures of the present invention have been described with respect to articulating leg limbs, it will be appreciated that the articulating structural members may be adapted to provide articulating arms or other limbs. For example, a toy animal may be provided with an articulating neck or tail comprising two or more substantial rigid structural member connected end to end by pivot joints, ball joints or the like. Likewise, the head of a toy figure or head/neck combination can be articulated, for example, with a pivot joint/mushroom joint combination to provide a head that can nod and rotate relative to the torso.
