8 Claims. ,(Cl. 46-149) The present invention relates to Van vinexpensive and readily assemblablevstructure fonmounting the legs of a walking doll so that rthe tlegs Will move, in synchronized manner when the .doll istw-alked maybe movedito sitting position when desired, .--and willihave a-maximumdegree of freedom 1of movement in alateraLor spreading direction when ineither of said positions.

Various mechanismshave been devised in the past for producing a walking doll, .thatis to say, a doll in which the legs are interconnected by ,mechanism effective to cause oneleg to swing rear-wardly when the other legis moving forwardly, thus permitting the doll to be grasped byla hand andpulledovenaffloonor supporting surface,

the legs moving to simulate walking. Insome structures of the prior art-the'head of thedolliis operatively connected to the leg-moving mechanism so'that the head will swing from side "to side in synchronized relation to the walking.

it is most clesirablelthat the legsbe releasably connectedto the'mechanism used to synchronize the Walking "movements thereof so "that .the legs .can'be moved to a sitting position when desired, thus enabling the doll to be self-supporting when placed onua floor ortable in that "position. 'It' is importantintliis' regardfthat the legs should be spreadable in order ito providedaterabas wellias frontal support for the doll'body.

The present-inventiophas for its object 'the "production of a mounting arrangement for dollsdegs in a"walking doll or the like in which"the-legsare readily'movablebetween standing or -walking and sitting positions,-in'which -a definite frontal angular relationship between legs and body is provided P for each of said positions, "in which the legs-are spreadable t-an appreciable degree no'matter in which position theymay be, in whieh-standard hollow doll bodies and legs rrnay be employed, and-in which the leg moving mechanism is inexpensive, "andreadily manuof the legs L or moving members and ea gpa'ir: of angnlarly oriented grooves =.0n-,the other, the; pin beingreceivable in one or the other of the grooves depending upon-whether .the tlegeis to berin .standing or sittingposition. fBy .reason of thepin and groovetinterconnectionhthetleg, .whether in standing or sitting ;position, 'is pivotalahout thepin as an axis, thus permitting thelegsto be spread to anydesired degree. Since two grooves are provide'd, one corresponding to the standing position of theileg and the other corresponding to the sittingposition thereof, the angular relationship of 'the'legs to'theibody in each of those positions is definitely fixed and the degree "to whichthelegs may "be spread is-independent thereof.

To the accomplishment of theraboveaand to such'other objects as may hereinafter: appear, the present invention relates to the structurefor .mounting vand interconnecting the legs :of a walking doll as defined Iin the-following claims .andvas describedrintthisa specificationtaken together with the accompanying drawingsin which:

Fig. 1 is a front elevational View, 2 partially .broken away and-.crossisectioned, -.of\a wa'lking...doll,in which the present invention is incorporated;

Fig. 2is acrosssectional .viewthereof taken .along the line.22 of Fig.1;

Fig. 3 is anexploded threequarter perspective view of the operative parts of theleg mounting and moving mechanism; and

Fig. 4 is a cross sectional .view of one ofthe movable ,members shown inFig. 3.

The doll comprises abodyl of conventional construction having apertures llat ,theilower ends-thereof through which the upperportionsoflegsdpassinto the interior of the hollow body 2, the cooperating surfaces of vthe apertures 4 and the legs ,6'beingsubstantially spherical so as to permit theproper degree of movement of the legs 6 relative to the Lbodys2. The legs 6 themselves are hollow, as is customary, and have aperturesSformed therein through which access to-theinteri'or of the legs 6 vis possible. "Tubularprojections It extend inwardly from the "front and rear walls of thelegs 6 opposite the apertures S, and a .pin 12 is mounted in thoseprojections so as to extend across the interior of theleg, the projections Id and pin "12, as :willbe seen, together defining an axis aboutwhich'the legs 6 may pivot for spreadingpurposes.

MountedWithin the bodyl andibetween the body apertures 4 is a -supporting element 14Lhaving cylindrical ends 16 and "having an ax'ial passa ge 18Jtherethrough. A centtral upward projection 20 is ;preferabl yformed integral jtherewith,. said projection having a vertical aperture22 "into whichthe end "2413f operating -shaft'26 .is received, :that shaft having an integrally vformed pair "of looped "portions"28=positioned above thetip 24 and,extending*to either side-tlrereofand over'the cylindrical ends '16 of the supporting "element 314.

A-;pair of substantially identical movable members generally designated *BU-are rotatably mounted, one on each --of the cylindrical element .endsfl6. Each of 'the movable 'merribers 30iispreferablyformed in onep'ie'ce by a molding operation -or-the like :and comprises 'a first portion 32 having an inner axial passage 34 of a size slightly larger than the exterior of the "element-end 1'6'and receivable'thereover, thejflrstiportionl32 ofth'e movable mem- -ber 30 thus constitutinga bearing'portionby means of 1 whichthe member 30 isrotatablvmounted .on 'an appropriate cylindrical end 16 o'fthesupporting element '14. :The movable member "30 -includes a second portion 36 which extends out "fromth'e first ,portion 32 toward the body apertures 4 and which is adapted to .pass through *theleg apertures .8 and thusenter thehollow interior of the legs 6.

The end surface38 ofithistsecond membenportion 36 is provided with apair of grooves 40 and '42, those grooves being angularly related'to one another and preferably oriented substantially perpendicular "to one another, the angular relationship betweenthe grooves 40 and 42 corresponding tothe idesired 'diiference in frontal angular position of the "legs 6 in standing an'd'sitting position respectively. A-s'here'disclosed the groove '40 is employed to determine the "sitting position of the legs "6 and the groove 42 is employerbto determine the standingtpos'ition "thereof. The groove 40 intersects theaxis rof'rthe member 30 while the groove42, although substantially perpendicular to the groove '40,, "is positioned :somewhatlbelow theaxis of'the member 310. 'I-Ience:when'the"legs"6 are in "st-anding'position theywillnot'otily be differently angularly oriented with respect to the body 2 but will also be positioned slightly lower with respect to the body 2 than when they are in their standing position, this being desired in order to provide proper clearance for the legs 6 as they move within the body apertures 4. The width of each of the grooves 40 and 42 is such that the pin 12 and/or the opposed tubular projections are receivable and rotatable therein. The tubular projections 16 may be considered as thickened portions of the pin 12, and hereafter when the pin 12 is referred to it will be understood that the projections 18 are included.

The second member portion 36 is provided with an axial passage 44, preferably somewhat smaller than the axial passage 34 in the first member portion 32 so as to define a shoulder 46 where they meet, and a rubber band 48 or other spring tension device passes through the axial passages 44, 34 and 18 and is connected at opposite ends, by means of books 50, to the pins 12 of the legs 6. The action of the resilient tension member 48 is such as to cause the legs 6 to move inwardly until the pins 12 come into contact with the end surfaces 38 of the moving members 30, the pins 12 thus tending to fit into one or the other of the grooves 49 or 42. It will be noted that the groove 42 has comparatively steep sides, whereas the groove 46 has sides 52 which are equally steep and opposite sides 54 which are much more gradually inclined, the gradually inclined sides 54 being directed toward the groove 42 corresponding to the standing position of the legs in the direction in which the pins 12 carried by the leg 6 will move when the legs are moved from sitting to standing position.

The legs 6 are interconnected for alternate back and forth movement to simulate walking by means of pins generally designated 56 secured to and extending upwardly from the movable members and entering the loops 28 formed in the shaft 26. Hence as one leg 6 is moved forwardly, the pin 56 operatively connected thereto will engage the loop 28 through which it passes and cause the shaft 26 to rotate, the other loop 28 moving the pin 56 passing therethrough so as to cause the leg 6 operatively connected thereto to move in the opposite direction. Since the pins 56 project from the moving members 30 to a considerable degree, they must be fairly strong and hence are preferably made of metal or the like. As a result they cannot readily be made integral with the moving members 30, which are preferably formed of some suitable moldable plastic material. In order to facilitate assembly of the pins 56 with the moving members 30, the pins comprise an upwardly projecting finger 58 and a bottom loop 60, the size of the loop being such as to pass through the axial passage 34 in the first member portion 32 but not through the axial passage 44 in the second member portion 36. A slot 62 is formed or cut in the first member portion 32 and extends from the end surface thereof to the shoulder 46, the slot having a width sufficient for the finger 58 to pass therethrough. The pin 56 may be mounted in place on the moving member 30 by sliding the finger 58 through the slot 62 while the loop 60 passes through the axial passage 34, and after the pin 56 has been moved all the way in, the loop 60 abutting the shoulder 46, the plastic material of which the moving member 30 is made may be distorted at the slot 62, as by the use of a heated tool, so as to fix the position of the pin 56 relative to the moving member 30.

As here disclosed, the shaft 26 extends upwardly through the neck portion 64 of the body 2 and into a hollow head 66 mounted on the neck portion 64. A cupshaped bearing member 68 is maintained in axial position along the shaft 26 by means of washer 70 and staked portions 72 on the shaft. The head 66 is provided with a bracket 72 through which the shaft 26 passes, the upper portion of that shaft being staked at 74 and a washer 76 being interposed between the staked portion 74 and the bracket 72. A spring 78 surrounds the shaft 26 below the bracket 72 and is held in compressed condition between washer 80 immediately under the bracket 72 and washer 82 held in axial position on the shaft 26 by means of staked portions 84. Each of the washers 8t) and 82 is provided with a central portion 86 snugly surrounded by the spring 78 which serves to hold the spring laterally in place. By reason of this mounting arrangement whenever the shaft 26 rotates, as will be the case when the doll is walked, the head 66 will move therewith. However, because of the frictional connection between the head 66 and the shaft 26, the normal or mid-point position of the head 66 relative to the body 2 may be adjusted at any time merely by rotating the head 66 relative to the body 2 while the legs 6 and the shaft 26 are stationary.

Because of the operative engagement between the pins 12 and the slots 4! or 42, a definite angular orientation of he legs 6 relative to the body 2 is provided whether the legs are in standing or in sitting position. Because the pins 12 are rotatable within the slots 49 or 42, the pins 12 define the axis of rotation about which the legs may be moved to vary the degree of spreading thereof whether the legs are in standing position (see Fig. l, where the broken lines indicate the legs when spread) or in sitting position (see Fig. 2, where the broken lines similarly indicate the spread position of the legs). The individual components of the moving and mounting mechanism are readily assembled merely by inserting the shaft end 24 in the aperture 22 and placing the moving members 30 in position on the cylindrical supporting element ends 16 with the fingers 58 of the pins 56 entering opposite loops 28. The head mounting structure may already be in position, provided the neck opening is large enough, or may be added to the shaft 26 after it has first been passed through the neck opening. The head may be secured in place merely by causing the prongs 88 of the bracket 72 to pass through appropriate apertures in the head 66, those prongs then being bent over as shown. It will be noted that the head mounting arrangement does not require modification of the conventional head structure per se.

The legs are readily assembled on the doll by passing the resilient tension member 48 through the mounting mechanism, engaging one hook 50 with the pin 12 of one leg 6, stretching the tension member 48 so that the other hook 50 engages with the pin 12 on the other leg 6, and then permitting the tension member 48 to pull the legs together. It will be noted that the legs themselves, when they engage with the movable members 30 and with the body apertures 4, serve in part to support the moving and mounting structure within the doll body. Additional support therefore is afforded by the bracket 72, which prevents the shaft 26 from moving downwardly, and by the frictional engagement between the shaft 24 and the aperture 22 into which the latter is received.

In order to move a leg from sitting to standing position or vice versa it is only necessary to move the leg outwardly against the action of the tension member 48 a sutficient distance to cause the pin 12 to become disengaged from whichever groove it may be in, and to then swing the leg so that the pin 12 lines up with and is received within the other groove. The somewhat inclined sides of the grooves 40 and 42 will act as cam surfaces causing the leg 6 to move outwardly a sufiicient distance provided that enough rotative force is applied to the legs.

The structure in question is exceedingly simple, inexpensive and easily assembled, yet it permits control of the position of the doll legs whether in sitting or standing position and it further permits pivotal movement of those legs in either position and to any desired degree independently of the position of the body.

While but a single embodiment of the present invention has been'here disclosed, it will be apparent that many variations may be made in the details thereof without departing from the spirit of the invention as defined in the following claims.
