11 Claims, 3 Drawing Figures PAIENIEDHAY mars SHEEI 2 OF 2 DOLL INCLUDING A JOINT MEMBER WITH FILLING OPENING AND GAS VENT THEREIN This is a continuation of application Ser. No. 311,227, filed Dec. l, 1972, now abandoned.

BACKGROUND OF THE INVENTION In the manufacture of one type ofjointed doll known in the prior art, the torso and limbs first are formed individually as relatively soft, thin-walled, hollow members from a suitable synthetic resin such as polyvinyl chloride and by any suitable molding process. Next. in order to give the doll body and a realistic feel, the hollow members are filled with polyvinyl chloride together with a foaming agent. Following that operation, relatively rigid. injection molded synthetic resin jointforming parts are glued to the limbs and to the torso. Finally, the joint-forming parts are connected to complete the assembly of the doll.

Owing to the relatively high temperature necessary to cure the polyvinyl chloride foam the molded jointforming elements cannot be adhered in place before filling. Moreover. the joint-forming elements of the prior art provide no filling openings.

We have invented a dolls limb attaching means which overcomes the defects of attaching means of the prior art pointed out hereinabove. Our attaching means enables us to fill the limb with foam after the attaching means has been assembled on the limb. It enables us to form a softer and lighter doll than are foam-filled dolls of the prior art. The cost of producing a doll embodying our attaching means is less than that of producing foam-filled dolls of the prior art.

SUMMARY OF THE INVENTION One object of our invention is to provide a dolls limb attaching means which permits the doll to be filled after securing of the attaching means to the limb and to the torso.

Still another object of our invention is to provide a doll's limb attaching means which enables us to form a softer and lighter foamed resin-filled jointed doll than do attaching means of the prior art.

A still further object of our invention is to provide a dolls limb attaching means which reduces the cost of producing a foam-filled jointed doll.

Other and further objects of our invention will ap pear from the following description.

In general, our invention contemplates the provision of means for attaching a limb to a dolls torso in which a cup-like socket-forming member of relatively rigid molded synthetic resin is secured in a recess formed in the relatively soft skin of the torso at a location at which a central boss on the member having a top formed with an opening and provided with cross slots forming resilient fingers can receive a frusto-conical molded plug connected by a neck to a base secured over a filling opening in a relatively rigid molded synthetic resin cup-like plug-mounting member adhered in a limb recess having a filling opening with the two filling openings aligned and with vent ports in the plugmounting member and in the limb recess in alignment to permit filling of the limb and curing of the foam after the plug-mounting member is secured to the limb.

BRIEF DESCRIPTION OF THE DRAWINGS In the accompanying drawings which form part of the instant specification and which are to be read in conjunction therewith and in which like reference numerals are used to indicate like parts in the various views:

FIG. I is an elevation of a doll provided with our doll's limb attaching means with a part broken away.

FIG. 2 is a sectional view of our dolls limb attaching means taken along the line 22 of FIG. I and drawn on an enlarged scale.

FIG. 3 is an exploded view of our dolls limb attaching means illustrating the details of the various parts making up the attaching means.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings, a doll, indicated generally by the reference character I0, incorporating our attaching means includes a torso 12, the skin of which is molded from a suitable soft synthetic resin such as polyvinyl chloride by any appropriate molding method. Preferably we rotational mold the torso 12. The torso I2 is formed with a head support 14 opening into the interior of the skin and provided with a peripheral retaining flange 16 adapted to be inserted within the head 18 so as to retain the head on the body in a manner known to the art. The neck 20 formed as an integral part with the head extends down to the shoulder portion of the torso. The torso 12 contains a filling 22 of any suitable material. For example, in a manner to be described hereinafter, we provide the torso 12 with a filling of flexible polyurethane foam. This material provides a softer, lighter and more desirable doll than does the polyvinyl chloride foam filling of the type used in the prior art. Polyurethane foam can be cured at room temperature.

The doll 10 includes a right arm 24, a left arm 26, a right leg 28, and a left leg 30. All of these limbs are secured to the torso 12 by our attaching means to be described in detail hereinbelow.

One of our attaching means indicated generally by the reference character 32 secures the left leg30 to the torso I2. In the course of molding the skin of the torso 12, we form a recess 34 in the left hip region of the torso. Similar recesses are formed at the locations at which the right arm, the right leg and the left arm are to be secured to the torso. If desired, we may provide the recess 34 with a central locating boss 36. The attaching means 32 includes a first cup-like socketforming element 38 which may, for example. be injection molded from a polyvinyl chloride to form an element which is rigid as contrasted with the soft vinyl skin. We mold the member 38 with a central boss 40 having a frusto-conical shape. We form a central opening 42 in the top wall 44 of the boss 40. At the same time, in the course of the molding operation, we form opposite pairs of slots 46 and 48 which divide the upper portion of the boss into a plurality of resilient fingers 50. In molding the element 38 we form the top 44 of the boss 40 with a thickness which tapers from a generally thicker region adjacent to the hole 42 to a thinner region at the periphery for a reason to be explained hereinbelow. As will be explained hereinbelow, before filling the torso 12 with the material 22, we cement the members 38 associated with the arms and legs in place in the recesses provided therefor.

We form the end of the leg 30 to be attached to the torso 12 with a recessed portion 52 having a central filling opening 54. We provide this recessed portion 52 with a gas exhaust port 56 at one side of the filling opening 54.

We injection mold a cup-like plug-mounting member 58 provided with a central recess 60 surrounding a filling opening 62. We also form a gas exhaust port 64 in the member 58 outside the recess 60. Before filling the leg 30 in a manner to be described. we cement the cuplike member 58 in the recess 52 with openings 54 and 62 in registry and with the two gas exhaust ports 56 and 64 aligned. An injection molded plug 66 connected to a base plate 68 by a neck 70 make up a plug-forming member which is adapted to be cemented in position within the recess 60 after the arm has been filled with the foamed plastic. We may form the parts 38, 58 and 66 from any suitable material such, for example, as CYCOLAC which is the registered trademark of Marbon Chemical Division, Borg-Warner Corporation. of Gary, Indiana, for a high-impact, styrene'type, rigid thermoplastic resin suitable for injection molding.

ln making a doll l incorporating our means 32 for attaching the limbs thereto, we first make the head in the usual manner and then mold the skins of the torso l2, arms 24 and 26, and legs 28 and 30, from a material such as soft polyvinyl chloride by a rotational molding technique. Next, we injection mold the relatively rigid parts including the cup-like member 38 having the boss 40 with its top 44 having an opening 42 as well as slots 46 and 48 providing the resilient fingers, the cup-like member 58 having the recess 60 with the filling opening 62 and the plug 66 connected by the neck 70 to the base 68. After those parts have been injection molded, the members 38 and 58 are adhered in the respective recesses 34 and 52 in the torso and in the ends of the limbs, it will readily be appreciated that the elements making up the leg-connecting means are the same as those making up the arm-connecting means but are of a somewhat larger size. Further in adhering the mem ber 58 in the recess 52 the openings 62 and 54, as well as the vent holes 64 and 56 are aligned.

Next, the filling operation takes place. We fill the torso skin 12 and the arms and legs with a flexible polyurethane foam with the filling and foaming operations performed at room temperature. The operation of filling the torso skin can be performed through the neck opening within the flange 16 without the necessity of providing any separate vent holes. In the course of filling the limbs such, for example, as the arm 26, the foam may be inserted through the aligned openings 62 and 54 and the gases are permitted to escape through the vent holes 64 and 56 in the course of the curing operation. When the filling operation is complete the base 68 is inserted in the recess 60 and adhered in place by use of a suitable cement.

When all of the parts have thus been made and foam filled, the neck portion of the head 18 is assembled over the flange 16. Similarly, the plugs 66 of all of the limbs are inserted in the openings 42 of their associated socket members 38. The doll is now completely assembled.

In use of a doll incorporating our means for attaching the limbs thereto, each limb is capable ofa full 360of rotation around an axis which is substantially that of the neck 70 connecting the plug 66 to base 68.1n addition, our construction permits of a limited movement of the limb in a direction perpendicular to the axis of pivotal movement. By way of example, we have illustrated an alternate position of the left leg 30 in broken lines in FIG. 1.

It is to be noted that we form the underside of the top 44 of the boss 40 with a slope of about 12. This slope ensures that the limb is securely retained in position on the torso. If an attempt is made to remove the limb as by moving it beyond a limited amount in a direction perpendicular to its axis of pivotal movement, the result is a wedging action which acts in a direction perpendicular to the sloped undersurface to offer resis tance to that movement.

it will be seen that we have accomplished the objects of our invention. We have provided a means for attaching limbs to a doll's torso which overcomes the defects of attaching means of the prior art. It enables us to fill the doll with foam at room temperature. It enables us to form a softer, more natural-feeling doll. It further enables us to produce a foam-filled jointed doll at less cost than is possible with joint-forming means of the prior art.

It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. This is contemplated by and is within the scope of our claims. it is further obvious that various changes may be made in details within the scope of our claims without departing from the spirit of our invention. it is, therefore, to be understood that our invention is not to be limited to the specific details shown and described.
