swan 2 BF 2 DOLL WITH F LEXIBLY-JOINED APPENDAGES BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to articulated toys, and more particularly to a joint arrangement therefor.

2. Description of the Prior Art The toy art is replete with articulated toys such as dolls with movable heads and limbs, and a wide variety of devices have been used for joining the head and limbs to the trunk. One type of doll has appendages which have a quiescent position, but the appendages are designed to oscillate about this position when disturbed. In order to minimize costs, simplified joining arrangements have been resorted to, which often are too fragile. Furthermore, such joints often result in oscillating movement of the doll appendages in a manner which is far from lifelike.

Lifelike movement of doll appendages, particularly the arms and legs, requires that they turn as though they were joined to the doll trunk by ball-and-socket joints placed in positions corresponding to those in the human or in animal bodies. This could be accomplished by a combination of balland-socket joints for establishing the pivot points and axes of twisting, and by springs or the like for biasing the appendages toward a quiescent position. However, the cost of such an arrangement can be high because of the number of relatively intricate parts and the difficulty of properly installing them in the limited space available.

OBJECTS AND SUMMARY OF THE INVENTION An object of the present invention is to provide simple toys with appendages that move in a lifelike manner.

Another object is to provide apparatus for use. in dolls to join the appendages to the trunk in a manner that causes lifelike movement from a quiescent position while biasing the appendages to return to the quiescent position.

In accordance with the present invention, dolls are provided in which the appendages are joined to the trunk by armatures of rubber or other elastic material in a manner that enables lifelike appendage movements. The armatures are elongated, and can bend in any direction as well as twist about their lengths. Thus, they perform the movements that a ball-andsocket joint or flexible neck vertebrae in many animals allows. The elastic nature of the armature biases the appendage back toward a quiescent state which is assumed when no forces are applied.

For appendages whichallow sufficient space, a bracket is provided on the trunk which supports the armature just inside of a desired pivot point. The armature bends or rotates about axes just outside of the position where it is held by the bracket. In the case of some appendages, the natural pivot point is within the appendage. For example, the human head can pivot about a point near the top of the neck, which is a substantial distance from the top of the human trunk. In these cases, a bracket on the trunk cannot be easily supplied that extends to just inside of the pivot point. To assure a desired location of the pivot point, the armature is made narrow at the desired location and pivoting is found to occur at this narrowest section.

The novel features of the invention are set forth with particularity in the appended claims. The invention will be best understood from the following description when read in conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 illustrates a doll l0 constructed in accordance with the invention, which includes a torso or trunk housing 12, head housing 14, arm housings I6 and 18, and

leg housings

20 and 22, which may be sometimes referred to as the head, arms, and legs, respectively. A first armature 24 has a central portion 25 and three

elongated armature portions

26, 28 and 30 for flexibly coupling the trunk to the head and arms. A second armature 27 has two armature portions 32 and 34 for flexibly coupling the trunk to the legs. The head, arms, and legs are constructed for unrestrained pivoting and movement toward and away from the trunk, within a wide range, by providing sufficient clearance between them, so that within this range, their movement is governed substantially by the armatures. The armatures are constructed of alresilient material, such as rubber or other elastomeric material, and they are thick enough to support the doll appendages in a quiescent position rather than to merely allow them to hang limply.

The armature 24 is designed to pivot the head housing about axes that pass approximately through a point 36 which is near the center of the neck portion 38 of the head. The

armature portions

28 and 30 are designed to pivot the arms about axes that pass through points 40 and 42, respectively, while the leg-supporting armature portions 32 and 34 are designed to pivot the legs about axes that pass through points 44 and 46. The head pivot point 36 is located approximately at the point about which a person turns his head to look up or down or to tilt it to one side. The arm and leg pivot points are at approximately the location of the joints in the human body about which the entire arms and legs pivot.

As also shown in FIG. 2, the trunk housing 12 includes a back housing section 48 and front housing section 50. Bracket means 52 is provided to hold the central portion 25 of the upper armature 24 on the trunk housing. The bracket means includes a central bracket portion 54 fixed to the back housing section, with slots 56, 57 and 58 (FIG. 1) that receive the central armature portion. The central bracket portion also includes a pin 59 that engages a hole 61 in the central armature portion. An opposing bracket portion 60, fixed to the front housing section, also engages the junction or central area of the armature, so the armature 24 is held between the two bracket portions. The bracket means also includes a pair of bracket members 62 (FIG. 1) and 64 (FIGS. 1, 2 and 3) fixed to the back trunk housing portion, and another opposed pair, including member 68 (FIGS. 2 and 3), fixed to the front housing section. These bracket members support the

elongated armature portions

28 and 30 at positions close to the

doll arms

16 and 18.

The pivot point 42 for arm 18 is located just outside of the positions of

bracket members

64 and 68. By placing the

bracket members

64, 68 near where the arms enter the trunk, the pivot point 42 is positioned at a location corresponding to the location of the ball-and-socket joint in a human body that joins the upper arm to the trunk. When the doll is picked up or shaken, the arm 18 pivots in a natural manner. If the

bracket members

64, 68 were eliminated, the arms would still move. However, the pivot point or bending area would move inward to a position just outside the slot 58 in the bracket member 54, and artificial-appearing arm movement would occur. The bracket members, such as member 62,. at the other doll arm 16 function in the same way.

Referring again more in particular to FIG. 1, the head 14 contains a plug member 70 which serves to join the head to the armature portion 26. The plug has a cylindrical outer shell 72 that is held within the neck portion. 38 of the doll head by a pair of flanges 74 and 76 at either end. The plug also has an inner tube portion 78 that surrounds an outer section of the armature portion 26.

The armature portion 26 includes a section 80 of reduced diameter to enable firm engagement with the walls of the slot 56 in the central bracket 54. Further out is section 82 of diameter L, section 84 of diameter S, section 86 with enlarged portions on either side of it for firm engagement with the inner tube portion 78 of the plug, and a tapered end 88 for aiding in insertion of the armature through the plug.

The pivot point 36 for the head is located approximately at the center of the reduced-diameter section 84 which has a diameter S. The pivot point is located further out than the section 82 because of its larger diameter L. The diameter S is about percent less than diameter L, which produces a bending moment of inertia, to resist the bending, which is only about one-half as great (since the moment of inertia I=rrR/ 4 for a circular cross section beam). The location of the pivot point 36, which is in the neck portion of the doll, corresponds to the pivot point usually employed in rotating the human head to look up or down or to tilt to one side.

Instead of employing a reduced-diameter outer section 84, the same location of the head pivot point 36 could be obtained by employing a bracket member fixed to the housing and supporting the armature portion 26 just inside of the pivot point. However, the head housing 14 must contain an integral neck portion 38 that extends down into the trunk. A separate head and neck that were pivotally joined often would create an artificial appearance. Accordingly, any such bracket member would have to have a tube portion that extended slightly into the neck, which would require a relatively complex member. By utilizing anarmature section of reduced diameter, a simple armature and support bracket are employed, yet a natural head pivot point location is obtained.

Referring now to FIGS. 1, 2 and 5, the second armature 27, which couples the legs to the trunk, is held by a central bracket member 90 on the back trunk housing portion 48. A post 92 on member 90 projects through a hole 94 in the armature, and into an opposed bracket member 96 on the front housing portion 50. A pair of

outer bracket members

98 and 100 support the armature portions 32 and 34 just inside the leg housings and 22. A slight spacing between the

bracket member

98, 100 and the leg housings is provided to enable leg rotation. The outer ends 102 and 104 of the armature portions are held by

supports

106 and 108 formed in the leg housings.

The armature portions 32 and 34 have

inner sections

110 and 112 of diameter M and

outer sections

114 and 116 of a smaller diameter N. The

sections

114 and 116 have numerous narrow splines protruding therefrom, and the diameter N is measured from the depths of the splines. As in the case of the armature portion that supports the head, the reduced diameter of

sections

114 and 116 results in the location of the leg pivot points 44 and 46 at these sections. The diameter M is about 37 percent greater than diameter N, which provides a moment of inertia of about three to four times as great as the

armature sections

114 and 116. This assures bending about the points 44 and 46, which is where the ball-and-socket joints of the human body are located.

It may be noted that in the leg armatures, the larger diameter M of

sections

110, 112 is substantially larger, by about 37 percent, than the diameter N of adjacent

outer sections

114, 116 where the pivot points are located, while in the head armature the diameter L of the larger diameter section 82 is only about 15 percent than the diameter S of the section 84 where the pivot point is located. The reason for this is that the human head is not supported on a ball-and-socket joint, but on vertebrae that enable bending, so pivoting substantially about a simple pivot point is not necessary. However, the thighs of the human body are pivoted about a single point, and a substantially concentrated pivot point for the doll legs is desirable.

The sections 66, 63 where the am armatures are held by the arm housing supports 65, 67, have numerous small splines. These splines allow the arm supports 65, 67 to slip on the armatures when the arms are twisted more than about 90 from their quiescent position, so the arms can be posed. In a similar manner, the

sections

114 and 116 of the leg armatures have numerous small splines that allow the legs to be posed by rotating them by more than about from their quiescent position so that they slip.

The back portion 48 of the trunk housing has an aperture 120 for facilitating secure holding of the doll in a case. As shown in FIGS. 6 and 7, a case 122 for holding the doll has a retainer 124 that projects through the doll housing aperture 120. The retainer 124 includes a circular base 126 that is held on the case, and an arrowhead-shaped member 128 that extends from the base. The member 128 has a wide flat portion 129 with a narrow neck that forms

grooves

130, 132, and has a pair of bracing bars 134 on either side.

The doll housing aperture 120 is elongated, with a pair of cutaway portions 136 at the center (as shown in FIG. 1). Four latching members 138 in the form of ramps are formed in the doll housing about the center of the aperture. in order to fasten the doll to the case, the arrowhead-shaped member is projected through the aperture, with the wide portion 129 of the member and elongated portion of the aperture aligned. Then the doll is turned 90 until the wide flat portion 129 of the retainer member is held between the latching members 138 on the doll housing. Removal of the doll from the case requires hard pressing in of the retaining member 124 while turning it.

Although particular embodiments of the invention have been described and illustrated herein, it is recognized that modifications and variations may readily occur to those skilled in the art, and consequently, it is intended that the claims be interpreted to cover such modifications and equivalents.
