No. 446,230 4 Claims. (Cl. 46-161) ABSTRACT OF THE DISCLOSURE An articulating dolls limb terminating in a cylindrical section having a reduced diameter section which is held in place by two pins which straddle the reduced diameter section, the limb being freely rotatable about its longitudinal axis and also having a degree of rocking movement about the axis of the pins.

The present invention relates generally to dolls, and more particularly to a limb member construction for a doll having multi-directional degrees of movement which permits posing the doll in a great variety of positions.

As may be readily appreciated, the play value of a doll is related to the variety of positions in which the doll can be posed, and also to the degree to which a life-like quality is simulated by the doll in these posing positions. Both of these results can be achieved by making suitable provision in the construction of the limb members of the doll, and in particular in the legs thereof, for movement of these limb members into these posing positions. For example, if human movements are simulated, each doll leg should be pivotal about its connection to the doll body to simulate leg movement about the hip joint, bendable at approximately a mid-point of its length to simulate knee movement, and also have the additional two degrees of movement rendering it twistable about its lengthwise axis as well as movable through leg positions of movement towards and away from each other. The last named degree of movement would permit, for example, a crossedleg posing position. The limb member features of construction which provide these degrees of movement should furthermore be operable to permit these movements simultaneously, and should not be too costly to incorporate in the doll, nor require complicated and difficult assembly procedures.

Broadly, it is an object of the present invention to pro vide a limb member for a doll which can be articulated through all the important degrees of movement simulating human movements, and greatly increasing as a consequence of these movements the posing position possibilities and play value of the doll. Specifically, it is an object to provide a construction for a limb member for a doll which has at least four degrees of simultaneous movement, and in which these movements are achieved with features of construction which are economically provided. More particularly, an object of the present invention is to provide a limb member having parts which lend them selves to mass production as plastic molded articles of manufacture, and which are adapted to be easily and readily assembled together with a minimum of skilled labor.

Broadly, a limb member construction demonstrating features of the present invention when employed as a dolls leg includes a skeletal mechanism pivotal about its connection to the doll and also pivotal about a point along its length, these two pivots corresponding to the hip and knee joints, and the mechanism having an appropriate degree of swinging movement about each of these two pivots. Additionally, the mechanism is provided with two more degrees of movement by features of construction thereof incorporated in the mechanism at a location between the hip and knee joints or pivots. These additional degrees of movement render the legs movable towards and away from each other, and also twistable about the longitudinal axis of each of the legs.

Specifically, a limb member construction demonstrating features of the present invention as related to a dolls leg includes an assembly of an internal limb member and an outer leg-shaped covering for the limb member. This limb member is comprised of two elements, pivotally connected to each other at a location corresponding to the knee joint; and at one end the member is additionally pivotally connected to the doll body so that it is pivotal about the dolls simulated hip joint. Between the hip and knee joints, the upper of the two limb member elements, or the element thereof which corresponds to the thigh, terminates in a generally cylindrical shape which is provided with a reduced diameter section spaced inwardly of the end thereof and about which the limb member is rotatable about its longitudinal axis for twisting of the leg. This end of this limb member element is rotatably received in a bearing block and retained therein by two transversely disposed pins which straddle: the reduced diameter section. The engagement of this element by these pins at the reduced diameter section thereof prevents removal of the limb member from the bearing block without interfering with rotation of the limb member. Additionally, the limb member can be rocked from one retaining pin to the other through positions of movement transverse to the leg longitudinal axis, thereby providing a most important degree of movement which, for example, permits a crossed-leg posing position which is not usually pos sible with a posing doll.

The above brief description, as well features and advantages of the present invention, will be more fully appreciated by reference to the followin detailed description of a presently preferred, but nonetheless illustrative embodiment in accordance with the present invention, when taken in conjunction with the accompanying drawings, wherein:

as further objects,

Reference is now made to FIGS. 1, 2 in which there is illustrated an identically constructed pair of legs 10, a demonstrating features for a limb member for a doll according to the present invention. The features of construction of the

legs

10, 16a and the features of the connection thereof to the doll body 12 which provides the advantages of the present invention could also be applied to the arms of the doll, and thus no limitation is intended by the description herein of these features with particular reference to the legs 10, 18a. Except for the subscript a in the general reference designation of the legs which preserves the separate identity of these legs and promotes a better understanding of FIGS. 1 and 2, this lower case subscript has otherwise been omitted as unnecessary in this description; the identical parts of the two

legs

18, 10a and of the doll body 12 being herein designated by the same reference numeral.

As is illustrated in FIGS. 1, 2, each of the

legs

10, 10a is identically constructed and connected to the doll body 12 so as to have four degrees of movement herein depicted by the double-headed reference arrows designated A1A4. Each of the

legs

10, 10a is comprised of an internal or skeletal mechanism in the form of a generally elongated limb member, generally designated 14, and a pliable leg-shaped body or covering 16 suitably disposed about the limb member 14. In essence therefore, the limb member 14 corresponds to a skeleton, and the covering 16, which is preferably fabricated of an elastomeric material to achieve a desired degree of pliability, provides both in appearance and function a simulated skin for the same. As will be more fully explained herein, and as is illustrated by leg 10 of FIG. 1, each of the

legs

10, 10a can be twisted about the longitudinal axis of the limb member 14 as illustrated by arrow A1, and also articulated through positions of movement illustrated by the arrow A2. Additionally, and as is illustrated by leg 10a of FIG. 2, each of the

legs

10, 10a is pivotal about the connection of the limb member 14 to the doll body 12 as depicted by the arrow A3, and as illustrated by the arrow A4 is also bendable, as at 18, at a point along the length of the limb member 14 which corresponds to the location thereon where the knee of each of the

legs

10, 10a would be expected to be provided.

Proceeding now to FIGS. 35 and to a detailed description of the limb member 14, it will be better understood how provision is made in the limb member 14 for the degrees of movement A1-A4 in each of the

legs

10, 10a. Included in the construction of each limb member 14- are two

elements

20 and 22 pivotally connected to each other so as to simulate knee movement in the posing of the doll 12 at the previously referred to kneejoint 18 of each

leg

10, 16a. Preferably each of the

elements

20, 22 are plastic articles of manufacture, and the respective ends which are pivotally connected to each other, as by the pivot pin 24 disposed in a tight fit through the aligning openings 25, are molded or machined in terminal circular configurations 211a, 2241 so as to facilitate pivotal movement about the axis of the pin 24. Element 22, forming the upper portion of each

leg

10, 10a or what corresponds to the thigh, will be understood to be generally cylindrical in shape, particularly at its uppermost end 22b. Either suitably molded in the first instance or subsequently machined in this end 221) of element 22, is a reduced diameter section 22c about which the limb member 14 is rotatable or twistable about its longitudinal axis. Rotatably receiving this cylindrical end 22b of the element 22 within a through bore 26, is a bearing block 28 which permits this degree of rotational twist A1 in the limb member 14 and thus in each

leg

10, 10a, while the cylindrical end 22]) of the element 22 is at all times securely retained and prevented from inadvertent detachment from the bearing block 28. Additionally, the block 28 and element 22 rotatably housed therein is movable through positions of movement depicted by the arrow A2. The degree of. movement A2 is of particular importance in the posing of the doll 12 since it permits a crossed-leg posing position and other posing positions which are not usually possible, and which greatly add to the play value of the doll 12.

To provide the simultaneous degrees of movement A] and A2 in each limb member 14, the connection of element 22 to the doll 12 is achieved through a limb-suspend ing member 30 having a socket 32 at one end and opposite end bifurcated extensions 34, The lower portion of the doll 12, or what corresponds to the lower torso, is provided with opposite limb-receiving openings 36 into which each of the

legs

10, 10a is rotatably disposed. The opposite side walls 12a of the doll lower torso 12 which are provided with these leg-receiving openings 36 are slightly inclined (see FIG. 6) so that there is a slight life-like converging attitude in the legs 10, when they are mounted in the openings 36. It should also be noted that by virtue of the upper portion 16a of the limb body or cover 16 following the contour of the extensions 34 of the member 31), the fullness of the thigh is realistically simulated.

Block 28 with element 22 therein is mounted between the bifurcated extensions 34, the interconnection of the block 28, the element 22, and the member 30 being achieved by spaced pins 38 force fit at their opposite ends in aligned openings 40 in the extensions 34. Between the extensions 34, the pins 38 extend through slots 42 in the block 28 which open into the vertical through bore 26 and which enable the pins 38 to straddle the reduced diameter section 220 of the limb member 14 beneath terminal larger diameter section 2211. By so engaging the element 22, the pins 38 prevent disengagement of the limb member 14 from the block 28 without interfering with or preventing rotative movement A1 of the limb member 14 about the reduced cylindrical section 22c straddled by the pins 38. Moreover, the limb member 14, as is best illustrated in FIG. 4, has a limited degree of rocking movement A2 about the transversely disposed pins 38. The extent of this movement may be limited by the oversized clearance C provided the slots 42, or in the alternative by abutment of the edges 43 of the block 28 against the undersurface 44 of the medial portion 30a of the member 30, whichever is more desirable since one movement stop is as effective as the other.

Providing the limb member 14 with the degre of movement A3 is the socket portion 32 of the member 30 which, as was previously mentioned, is rotatably mounted in the limb-receiving opening 36 of the doll 12. As is best shown in FIGS. 1 and 4, included in construction of the socket 32 is a reduced diameter section 32a bordered on opposite sides by

larger diameter sections

32b and 32c. The limb member 14 is disposed through an opening 46 in the upper portion 16a of the leg-shaped covering 16 into the hollow interior of this covering, the immediate surrounding covering portion 46a about the opening 46 being suitably shaped to snap into place about the socket section 32a and cover over the outer socket section 320. After completion of the subassembly of limb member 14 and covering 16, the limb member socket 32 is snapped into the limb-receiving opening 36 and is rotatable therein through positions of movement A3.

A doll 12 provided with limb member 14, either as

legs

10, 10a as herein described or as arms, is capable, by virtue of the degrees of movement A1-A4 of being posed in a great variety of positions, and has a simulated lifelike quality to a remarkable degree in these posing positions. Additionally, it will be noted that the limb member 14 or articulated skeleton of the doll 12, is interconnected part-to-part by an interfittin-g of one member into another. For example, the socket 32 fits within the legreceiving opening 36, the limb end 22b within the bore 26 of the bearing block 28, the pins 38 within the openings 40 and slots 42, and finally the pivot pin 24 within the aligned openings 25 of the

limb elements

20, 22. Thus, to retain the posed positions of the doll 12 it is necessary only to dimension the inteifitting parts so that there is sufficient frictional resistance to movement to achieve this result, and at the same time permit changing the posing positions by overcoming this frictional resistance when it is desired to do so.

From the foregoing, it should be appreciated that a limb construction 14 of the present invention applied to a posing doll 12 permits a variety of posing positions Which literally are too numerous to specifically mention. There is nevertheless demonstrated in FIGS. 1 and 2, two posing positions which illustrate the efiect of each of the four degrees of movement Al-Ad permitted by the features of construction of the limb member 14. Thus, demonstrated in FIG. 1 is a classic modeling position in which the legs 10, 1061 are spread a moderate distance from each other, and the leg smartly turned to the side; a posing position requiring compound leg movement. More particularly, required for this posing position is leg movement A2 about the pivot 28a located between the knee and hip pivots 18 and 3% respectively, and rotative movement All about the longitudinal axis of the limb member 14. In FIG. 2, the full line and phantom perspective representations of the leg 10a demonstrate posing positions of movement of this leg requiring pivoting movement A4 about the knee pivot 18 and pivoting movement A3 about the rotative axis of the socket 32 or what is herein designated the hip pivot 30b.

Reference is now made to FIGS. 7 and 8 in which a second embodiment of a limb member is illustrated, and in which the same but primed reference numerals are used to identify similarly functioning parts of each. This limb member embodiment also includes a socket construction 32 for being rotatably mounted in the body of a doll, and additionally is provided with a member 30' extending from said socket construction. The equivalent of a bearing block in the form of a spring member 28 is pivotally mounted with a rivet 38 on the extended end of the member 30'. In practice, the reduced diameter section 220' of the upper limb member or element 22' is rotatably mounted within said spring member 28. Thus, the upper leg element 22', as in the previously described embodiment, has pivotal movement A2 about the rivet 38' and also rotative movement A1 within the retaining spring member 28. Additionally, the entire construction is rotatable about the reduced diameter section 38a of the socket 32. and, although not shown, it will be understood that the lower leg element of the limb member is appropriately pivotally mounted, as at 25, to the terminal section 2201' of the leg element 22'.

A latitude of modification, change and substitution is intended in the foregoing disclosure, and in some instances some features of the invention will be employed without a corresponding use of other features. Accordingly it is appropriate that the appended claims be construed broadly and in a manner consistent with the spirit and scope of the invention herein.
