Filed Feb. 12, 1958, Ser. No. 714,756 18 Claims. (Cl. 46-149) This invention relates to a doll leg mounting and operatlng mechanism. An object of this invention is to provide such a mechanism which can function to effect the walking motion (as in applicants Patent No. 2,736,135, February 28, 1956) and in which the legs can alsobe moved to sitting position and crossed, in a manner closely resembling the corresponding human motion and position. When this mechanism is combined with suitable articulation of the knees, ankles, :waist, arms, etc., a wide variety of life-like poses become possible.

Practical embodiments of the invention are shown in the accompanying drawings, in which: FIG. 1 represents an elevation of a doll torso and legs in the seated, leg-crossed position made possible by the PIOVlSlOI'l of the mechanism described below; parts being broken away;

FIG. 2 represents a detail front elevation of the lower part of a doll body and upper parts of the legs, in standlng pOSlIlOl'l, connected by one form of the walking and leg-crossmg mechanism, parts of the body wall, leg and leg mounting being broken away and parts being shown ll'l section;

FIG. 3 represents a detail side elevation of the lower part of a doll body and upper part of the left leg, in sitting position, parts of the body wall and leg being broken away;

FIG. 4 represents a horizontal section, taken on the line IVIV of FIG. 3;

FIG. 5 represents a bottom perspective view of one form of leg-crossing mechanism, only the right leg unit being shown and part of the leg-mounting button being broken away;

FIG. 5a represents a detail bottom plan view of the mechanism shown in FIG. 5, parts being broken away;

FIG. 6 represents a rear perspective view of the mechanism shown; in FIGS. 5 and 5a, in the same adjusted position;

FIG. 7 represents a side elevation of the lower part of adoll body and upper part of the right leg, in sitting position;

FIG. 8 represents a vertical section taken on the line VIIIVIII of FIG. 7, the section of the leg in crossed position being shown in broken lines;

FIG. 9 represents a horizontal section taken on the line IXIX of FIG. 7, the outline of the leg in crossed position being shown in broken lines;

FIG. 10 represents a rear perspective view (comparable to FIG. 6) showing a modified form of mechanism in its leg crossing position;

FIG. 11 represents a front elevation of the lower part of a doll body and upper part of the legs, designed to be crossed by means of a simplified mechanism, and

FIG. 12 represents a rear perspective view of the simplified mechanism used in a doll body such as that of FIG. 11, with a right leg attached and moved to leg crossing position. 7

Referring to the drawings, the torso illustrated in FIG. 1 includes an upper body portion 1 and a lower body portion 2, suitably articulated in a manner constituting no part of the present invention, and legs 3 which are jointed at the knees (preferably as shown in applicants Patent No. 2,791,063, dated May 7, 1957) and also, if desired, at the ankles. Such multiple articulation is characteristic of the ballerina type dolls, but is not at all restricted thereto. As clearly shown in FIG. 1, the achievement of the seated leg-crossed position requires an additional articulation of the legs enabling them to be moved toward each other, in the. sitting position, to such an extent that the thigh portions 4, 4 are crossed, with the right knee to the left of the left knee and vice versa. This capability has, preferably, to be added to a reliable walking motion, and the mechanism should be adaptable to doll bodies of flexible (e.g. vinyl) materials as well as to rigid bodies.

As shown in FIGS. 2 to 6 the leg crossing mechanism is combined with a walking mechanism com-prising a horizontal plate 5 fixed to the body wall at, the points 6, 6 (approximately hip level) and a vertical plate 7 having its upper end secured to the middle of the plate 5 and its lower end terminating at the bottom wall 8 of the body between the leg openings 9. Leg supporting elements 10 have their wide flat vertical lower ends pivotally fixed by a rivet 11 or the like to the plate 7 near the bottom wall 8 of the body, the rivet 11 providing a horizontal axis around which the elements 10 can rock. The narrow upper ends 12 of the elements 10 project through slots 13 in the plate 5 and engage in openings through a rocker arm 15 mounted on a vertical pivot 16. The wide flat middle portions 10- of the elements 10 are disposed, preferably, to slant outward and upward, as disclosed in applicants Patent No. 2,736,135, cited above. 7

I11 order to provide the normal walking and sitting capabilities, each leg 4 is secured to a button 17 (shown here as being square but which may be round, as in FIG. 12), the button being backed by a metal cap 18 and secured to the walking mechanism by means of a post 19, fixed on said mechanism and having a head 20, combined with a spring 21 which bears strongly against the under side of the head 20 and against the enclosed side of the button 17. The cap 18 is provided with a small projecting boss 22 arranged to engage one or more suitably located depressions in the matching surface of the walking mechanism so as to hold the leg releasably in standing position, at least, and in other positions if desired.

The additional leg-crossing capability is provided by adding to the walking mechanism certain elements,

shown particularly in FIGS. 2, 5 and 6, which constitute in elfect a limited-motion hinge between the elements 10 and the leg-attaching parts 17-21. One part of the hinge is shown as being a generally U-sh-aped piece secured to the middle portion 10 of the element 10 and having substantially horizontal upper and lower sides 23 and a substantially vertical end 24 which projects somewhat farther from the surface of the portion 10 than do the sides 23. The second part of the hinge comprises a fiat portion 25 (on which the post 19 is mounted) and inwardly folded horizontal flanges 26, so spaced as to embrace the sides 23 of the first part to which they are secured by means of a hinge pin or pins 27. The relative locations of the hinge axis, of the portion 25 and of the end 24, as well as the ends of the flanges 26, are preferably such that the outer edge of the end 24 and/or the projecting ends of the flanges 26 will limit the extent of the hinging motion, approximately as indicated in FIGS. 5, 5a and 6; said edge may also engage the cap 18 throughout the hinging motion so that the hinged parts will tend to spring toward their closed positions and to be retained resiliently there. The opening motion is preferably limited to a range short of the dead-center position, as indicated by the angle a in FIG. 5a in order to cause the hinge-closing tendency just described. The hinge axis is located near the front edge of each leg supporting element, and it will be evident that the interposition of the hinge between the elements 10 and the leg-attaching parts 1721 makes it possible to swing the legs toward and across each other from the normal straight-out sitting position. Rotation between standing and sitting positions takes place around the axes of the posts 19, while rotation from straight sitting to leg-crossed sitting takes place around the axes of the hinge pins 27.

It will be noted that the upper parts of the legs are turned through almost 90 between the thigh zones and the points of attachment and that they are rather deeply recessed on the inside of the tum 4, to provide clearance between that part of the leg and the adjacent edge of the leg opening 9. Due to the advantageous location of the hinge axis the clearance problem is generally not serious.

With certain shapes and sizes of dolls, it may be found desirable to shift the hinge axis away from the front of the body when the legs are crossed and a simple means for efiecting this result is shown in FIGS. 5 to 9.

All that is required is to. provide a slot 28 (in the plate 7) for the rivet 11, so that the whole moveable mechanism may be moved a short distance toward the rear when the legs are in crossed position. By making the forward end of the slot 28 its highest part, the mechanism will automatically stay at that end when the doll is walking and thus creating an upward thrust between the legs and the body. The shape of the legs and of the leg openings may also be relied on to maintain the rivet 11 (the walking axis) in its proper forward position. For instance, as shown in FIGS. 7, 8 and 9, the distance of rearward shift (with a downward component) is identified as x, which takes advantage of the fact that the inward clearance y between the upper part of the leg and the adjacent edge of the leg opening, with the leg connection in its rearward (and downward) position is substantially greater than the corresponding clearance 2, measured with the leg and walking mechanism in the standing or walking position.

An alternative, but somewhat more complex, mechanism is shown in FIG. 10 wherein the vertical plate (corresponding to plate 7) is indicated at 29, having a leg supporting element 30 (corresponding to element 10) pivotally connected thereto at 31. In this case a generally flat member 32, having a guiding flange 33 along its bottom is slid-ably secured to the element 30 by means of the headed stud 34, passing through the horizontal slot 35. The member 32 constitutes the first part of a hinge and the member 36 is the second part, said parts being hingedly connected as indicated at 37, for example. The member 36 is provided with a locking pin 38, so positioned as to project through a hole 39 in the member 32 and also, when the member 32 and element 30 are in the position shown, through a matching hole (not shown) in the element 30. It will be evident that the pin 38 will thus lock the element 30 and member 32 in the position shown, when the hinge is closed, i.e., in the walking position. When the hinge is open (as in FIG. 10) the member 32 can be displaced rearwardly (in the direction of the arrow) for reasons explained above. A leg mounting button 40 is shown, and it will be understood that its details are, in general, similar to those of the button previously described.

In addition to the pin 38, the member 36 is provided with a bent spring finger 41 adapted to snap over the corresponding edges of the member 32 and element 30 to hold the hinge releasably in'its closed (standing or walking) position.

' A simpler alternative arrangement, which may be quite adequate particularly in smaller or less expensive dolls, is shown in FIGS. 11 and 12, where a leg supporting element 42 (similar to the elements 10 and 30), pivotally secured to a vertical plate 43 (similar to plates 7 and 2?) for rocking movement about a horizontal axis 44, is

hingedly connected at its front edge, as indicated at 45,

to a plate 46. The free end of the plate 46 is bent to form a spring flange 47 (comparable to finger 41) adapted to snap over the rear edge of the element 42 to hold the hinge releasably in its closed position. A doll leg 48 mounted on a round button 49 is secured to the plate 46 in any suitable manner, as by a post 50 and spring (not shown), and the button surface may be provided with a depression, such as the groove 51, arranged to be engaged by a projection 52 on the plate 46 to hold the leg releasably in standing position (FIG. ll When legs mounted on supports of the character just described are turned forward to the sitting position (separating the groove 51 from the projection 52 by more or less), they can also be crossed by swinging them horizontally toward and past each other; the leg-crossed position of the right leg supporting mechanism being shown in FIG. 12. Due to the somewhat exaggerated lateral offset at the upper part of the leg (FIG. 11), there is sufficient clearance so that no rearward shift of the mechanism is needed in this case. The mechanism also has no stop for limiting the extent of the leg-crossing movement, since the leg openings in the body constitute a satisfactory stop, particularly in a relatively small doll.

It will be understood that various changes may be resorted to in the material, form, construction and arrangement of the several parts without departing from the spirit and scope of the invention, which is not intended to be limited to the details herein shown and described except as they may be included expressly or by necessary implication in the claims.
