4 Claims. (Cl. 46-149) This invention relates to a walking device and is a continuation-in-part of applicants prior application, Ser. No. 304,838, filed Aug. 27, 1963, and since abandoned. The invention has for One of its objects the provision of a device having legs supported thereon for movement in simulation of walking when the device is held in a position for frictional engagement of the lower ends of said legs on a supporting surface and is moved forwardly.

Heretofore devices, such as dolls or figures representing human beings, have been designed with movable legs intended to swing alternately in simulation of a walking movement, but the body supporting the legs must be swung from side to side so that the leg moving forwardly and oppositely to the other leg will clear the ground. The manipulation necessary to effect this walking movement is diflicult for many children, and in any event, the movement of the doll is an ungraceful waddle, rather than the natural stride of a walker.

One of the objects of the present invention is the provision of a walking device having a body and at least two legs that are adapted to automatically swing with a natural walking stride when the body is held by a hand of the operator and is moved forwardly, and in which device the foot on the forwardly moving leg clears the ground without requiring any special manipulation of the body of the device.

Another object of the invention is the provision of a walking doll made in simulation of a human being, that is simple and economical to make, and which legs are adapted to move to simulate natural strides without interference of the ground with either foot, and without other manipulation of the doll than to move the body forwardly with the foot of the advanced leg on the ground in frictional engagement with the latter during substantially the entire rearward movement of the leg from its advanced position.

An added object of the invention is the provision of a walking doll made in simulation of a human being that is not only adapted to simulate walking, when moved over a supporting surface in engagement therewith, but the legs are constructed and arranged so that the legs will readily support the doll in a seated position on such surface.

Yet another object of this invention is the provision of a walking mechanism for a doll whereby the legs of said doll can be independently moved for acrobatics and wherein the length of the Walking stride is variable in length.

Other objects and advantages will appear in the description and in the drawings.

FIG. 13 is an elevational view of the right side of the mechanism of FIG. 12 showing the rear leg in a kicking position.

FIG. 14 is an elevational view of another modification of the walking mechanism of this invention.

In detail, the doll, generally designated 1, (FIG. 1) is made to simulate a small girl, and insofar as all outward appearances are concerned, the doll may look like any other doll. In the present instance, the legs 2, 3 are movably connected to the body of the doll and will take realistic walking strides when the sole of the foot or shoe of leg 2 frictionally engages the ground and the doll is pushed or moved forwardly. The walking mechanism, under the influence of the power applied to cause said forward movement, will act to swing the other leg 3 upwardly and then forwardly as the leg 2 moves rearwardly relative to the body.

The lower portion of the body of the doll is generally designated 4 (FIGS. 2, 5), and this portion is formed with a downwardly opening recess 5 in the upper side of which a socket 6 opens in a downward direction. The leg carrying member 7 (FIG. 3) is adapted to fit in said recess with the upward projection 8 on said member fitted in the socket 6. A pin 11 is adapted to extend through the body portion and projection 8 to firmly, but releasably, hold the leg carrying member 7 to the body.

In the description and claims, wherever the words forward, forwardly, front, rear and words of similar connotation are used, they are used with reference to the front or rear side of the doll; the forward side being the front side.

Referring to FIG. 3 the leg carrying member 7 is formed with fiat, opposite lateral sides, and adjacent to the forward edge of the member are corresponding lateral projections 9 terminating in lower edges that are preferably substantially even with the lower forward edge 12 of recess 5 ((FIG. 2). Along the rear edge of the members are corresponding lateral projections 13. One function these projections perform is to engage the opposite lateral inner faces of the recess 5 so that the member 7 will be equally spaced from the opposedly facing surfaces of the sides of said recess.

The forward lower edge 12 of recess 5 terminates substantially higher than the lower rear edge and the lower lateral sides of the recess.

The flat opposite sides of member 7 between the forward projections 9 and the rear projections 13 are formed with circular, corresponding coaxial recess 14 of equal depth, having a web 15 between them (FIG. 3).

The central web 15 is centrally apertured to provide a bearing for a crank shaft 16 (FIG. 2) having oppositely disposed crank arms 17, 18 at opposite ends thereof disposed within recesses 14, (FIG. 3) and which arms are respectively formed with crank pins 19, 20 (FIG. 2) that project oppositely outwardly of the pair of recesses 14.

Crank pins 19, 20 respectively extend into openings in the upper ends of leg supports 21, 22 that are rigidly connected with legs 2, 3, respectively.

Leg supports 21, 22 provide means for connecting the legs to the body of the doll through the cranks on crank shaft 16, and these supports are preferably fiat sided at their upper ends with their flat sides parallel with the flat opposite outer sides of the leg carrying member 7 a and with the opposed inner lateral surfaces of the recess 5. Thus the legs will not rotate about their longitudinal axes, but are free to rotate relative to the axes of the crank pins 19, 20 in planes parallel with the flat opposite sides of member 7.

The upper and laterally outermost portions of the pair of legs 2, 3 project upwardly, as at 24 (FIG. 2) to extend over the lowermost portions of the body, and their outer surface contours are preferably convexly curved to simulate the natural appearance of the legs of the figure that the doll represents. These leg supports 21, 22 of the doll represented in FIG. 1 project upwardly from the adjacent sides of the pair of legs, and the outer lateral surfaces of the lower portion of the body, which are lapped by portions 24, are preferably substantially complementary in cross-sectional contour, and are relatively close to the adjacent surfaces of the portions 24.

Secured to the leg carrying member 7 and extending transversely through the latter parallel with crank shaft 16 and above the level of the latter is a rod 25 (FIG. 2) i having end portions 26 (FIG. 3) that project oppositely outwardly of the lateral fiat surfaces of said leg carrying member.

The upper portions of leg supports 21, 22 are the same, and each is formed with an arcuately extending forward cam surface 27 that extends behind the projections 26 of rod 25 and that are adapted to slidably engage said projections.

As seen in FIG. 2, the opposed lateral sides of the recess 5 extend over the outer ends of the crank pins 19, 20 and over the outer ends of projections 26. Thus the legs cannot come off the projections, and the cam surfaces 27 will always be in a position to engage the projections 26 during walking movement of the doll.

The relationship between the crank and the projections 26 determines the character of the stride taken by the legs during a walking movement, such as a longer or shorter stride, and, of course, the throw of the cranks also effects the stride. These relationships may be varied to suit the circumstances.

FIG. 4 diagrammatically illustrates the movement of one of the legs in a walking operation. Since the crank pins are opposite to each other and the cam surfaces 27 are the same, and inasmuch as the projections 26 are the same at opposite sides of the doll, it is obvious that FIG. 4

could represent the movement of either of the legs. However, due to the oppositely offset crank pins, the legs at opposite sides of'the body will move oppositely. That is, when one leg is carried upwardly by the crank pin, the other will be lowered, and when one moves forwardly, the other will move rearwardly. For example, the two full line positions 28, 29 (FIG. 4) substantially correspond to the positions of legs 2, 3 of FIG. 1, and it will be seen that the crank pin is substantially at opposite sides of the center of the circular recess 14. In position 29 the crank pin 20 is near the uppermost point in its arc, while in. position 28 it is approaching its lowermost position, the revolution of said crank pin being counterclockwise as seen in FIG. 4.

In describing the walking operation, in FIG. 4 the sole 30 of the leg 2 has just moved into contact with the floor 32, and has moved slightly rearwardly relative to the body thereby rotating the crank to cause crank pin 20 (FIG. 4) to move upwardly and to thereby lift the foot of leg 301T the floor. Upon moving the doll forwardly while the sole 30 on leg 2 is in frictional engagement with the floor, the cam surface 27 on the leg support will be against the stationary control projection 26 which will result in the transmission of the forwardly moving force to the crank pin 20 to rotate the crank and to carry the leg 3 upwardly as the pin 20 moves upwardly, and as soon as the sole of the foot on leg 3 is free to swing forwardly along the line 33 and it is the engagement between the stationary projection 26 and cam surface 27 that causes the lower end of the leg or the foot to follow line 33. The dot-dash line position 34 of leg 3 is one in which the foot of leg 2 would still be in engagement with floor 32, but leg 3, now in position 34, has almost reached the point where the foot will move downwardly generally along line 36 to the position 28 of leg 2 in FIG. 1 and, as soon as this occurs, the tip of the toe of the leg 2 (which will then be approaching the full line position 29 of leg 3) will be ready to leave the ground, and it will leave the ground to move to and past position 29 as leg 3 moves to position 28 and dot-dash line position 35.

The movement of the elevated leg from its forward position 34 in which the sole of the foot is above the ground to a position along line 36 into engagement with the floor is relatively fast and, immediately upon the sole engaging the floor, the rearward leg will quickly be elevated to position 29, so that is no point where there is any sliding of the feet on the floor.

The soles 30 of the feet or footwear are preferably slightly convex in cross-sectional contour, lengthwise of the foot, so it will roll over the surface of the floor about an arc having its center approximately at the crank pin as the doll is moved forwardly, and this sole may have a friction surface so as to resist sliding on a polished surface.

One of the advantages of the doll that is illustrated and described is that it may be readiy sleated on the floor, since there is nothing to prevent the lower ends of the legs from swinging forwardly to the position shown in FIG. 5. The lower, forward edge 12 of the body of the doll limits the forward swinging of the body of the doll relative to the legs to a position in which the body of the doll is upright, and this will result in said edge engaging the forward edge of the elevated leg support, which in FIG. 5 is the support 22, and rotating the crank so that pin 20 is lowermost, relative to crank pin 19. Pin 20 is forced into this lowermost position by the camming action of edge 27 of support 22 engaging edge 10 of projections 9. When a doll is lowered to a sitting position, support 22 will always engage edge It first since there is a cut-away 37 at that point of engagement on support 21. Thus, pins 20 Will be cammed downwardly. Obviously crank pin 19, under this circumstance, must move upwardly, and is allowed to do so since the forward lower edge of the leg support 21 is cut away as at 37 to permit the upward movement of support 21 under the influence of downward movement of leg support 22.

FIGS. 6, 7 merely show economical and practical structure for securing the leg supports 21, 22 to the legs. The legs may be of conventional, semi-rigid plastic material formed with upwardly opening sockets 38 in which the lower portion of each rigid leg support (or 21) is fitted, and a pin 39 may secure each support in the socket, or they may be cemented in place, if desired, so as to be integrally connected with the legs.

Also seen in FIGS. 6 and 7 is a substantially horizontal groove 31 extending for a distance around leg 2, it being understood that a similar groove is so located on the inner side of leg 3. This groove is adapted to receive an elasticized or drawstring tightened pantie leg or the like therein to prevent said pantie leg from riding up over the edges of the legs and exposing and possibly becoming entangled in the walking mechanism.

In FIG. 8 a modification of the leg supports is shown in which the projections 26 each project into a straight vertical slot 40 formed in the upper end portion of each leg support 43, thus providing a cam surface 42 opposite to a cam surface 43. The surface 43 corresponds to cam surface 27.

A doll provided with this structure cannot be seated without the addition of leg hinges or the like, but it can be walked backwards, which cannot be done with the doll hereinbefore described. It also hastens the step and permits walking downhill. The cam surface 42 on each support performs the same function as cam surface 43 when the legs move in a direction opposite to the direction in which they move when the doll is Walked in a forward direction.

FIG. 9 illustrates a walking animal having two front legs 44 and two rear legs 45. They operate in the same manner as the legs of the walking doll, but in this instance the front and rear legs are secured to leg supports 46 (FIG. 11) that, in turn, are inside the body 47 and which supports are rigidly connected with the legs by pins 48. These pins extend through circular openings 49 formed in the sides of the body (FiG. 11). The lateral outer flat sides of body 47 extend convergently downwardly and the adjacent surfaces of the legs 44, have surfaces respectively parallel to the sides of body 47, and with this arrangement, the crank shaft 50 is flexible, so that its ends may be perpendicular to the flat, adjacent surfaces of the body and legs and with the leg supports 4-6, which are parallel with said surfaces.

A saddle member 52 is within body 47 rigid therewith and has central bearings 53 in which the central portion of each shaft 56 is rotatable, and a sprocket gear 54 or the equivalent, is secured on each shaft 50 between bearings 53. A sprocket chain 55 (FiGS. 10, 11) connects the sprocket wheels so the shafts 50 will rotate together and in proper relation.

The sides 56 of saddle member 52 are adjacent the sides of body 47 and rotatably support the ends of shafts 5%, while a crank is secured on the end of each shaft in positions between the sides of the saddle member 52 and the sides of body 47. These cranks have oppositely disposed crank pins 57 that rotatably extend into the leg supports for effecting the movement of said legs in exactly the same manner as legs 1, 2 of the doll are moved when the latter is moved. Projections 58 (FIGS. 10, 11) slidably engage the forward cam surfaces 59 of supports 46 to control the swinging of the legs.

If desired, coil springs or rubber bands 60 (FIG. 10) may be respectively connected with the leg supports 46 and the body to yieldably hold the cam surfaces 59 on said supports against projections 58, and this structure may be employed with the doll, if desired. It provides a slightly faster action of the legs during a walking operation and helps turn the crank when the forward leg is in the most forward position. Less tension is on the rear leg.

The crank pins on the forward shaft 50 are preferably offset so that the forward leg 44 on each side will swing oppositely to the rear leg 45 on the same side when the animal is moved forwardly, and a stick 62 may be connected with the back of body 47 (FIG. 11) at the most suitable point to assist in supporting the dog, while the child is in a standing position, and for moving the animal forwardly.

As indicated in the drawings, the center of gravity of the doll body is preferably at a point that is rearwardly of the crank shaft. This lessens any tendency for the body to fall forwardly during manipulation of the doll; therefore makes it easier to move the doll properly in a walking operation.

It should be noted that the arrangement of the crank shaft and legs, as illustrated, is such that as soon as the downwardly moving, forwardly swung foot contacts the ground or supporting surface, as the operator pushes the doll forwardly, the crank shaft is in a position to continue its rotation, rather than to reverse the direction of its movement. This is important.

The invention as shown and described herein is illustrative of the invention, but it is to be understood that the invention, as hereafter claimed, may include other constructions, arrangements of parts, details and features.

For example, the entire body of a doll, including the walking mechanism could be covered with a skin-like plastic or fur-like covering to completely hide the walking mechanism and simulate natural body covering, said covering being so constructed as to allow for freedom of motion of the moving parts of the doll.

Further, in the mechanism described in FIGS. 1-7, in order to provide a doll that could easily walk downhill, at least the upper portions of leg supports 21, 22 could be made of magnetically attracted metal and the pin 25, or similar camming member, could be in the form of a permanent magnet, which structure would yieldably urge the leg supports to the position of FIG. 3 and at the same time allow the legs to be moved to the sitting position of FIG. 5.

Other modifications of the walking mechanism described are illustrated in FIGS. 12-14.

In FIGS. 12 and 13 a leg carrying member 70, similar to member 7 in FIG. 3, is used to support leg structure 71, 72 by means of crank pin 73.

The opposed arms of cranks 73 may be recessed in a counterbore 74.

A rod 75 may extend through carrier and the projecting ends of said rod serve as camming members for engagement with the forward camming surfaces 76, 77 of the upper ends of leg structures 71, 72 respectively.

In the construction of dolls having a walking mechanism such as that described in FIGS. 12-14 wherein the cam surfaces on the upper extensions of the leg members are straight, it may be desirable to position the rod or stop member 83 sufficiently forwardly of the horizontal axis of rod 73 to allow both legs 71 and 72 to assume substantially vertical, substantially parallel, positions relative to each other when the doll is lifted from the surface over which it may be walked and the legs are hanging freely. The effect of offsetting the camming or stop members forwardly of the horizontal axis of cam shaft 73 is accomplished in the devices of FIGS. 1-7 by having the camming surfaces receding away from the stop members. Thus in both devices, whenever a doll is lifted free from the surface over which it may be moved, both legs will hang together beneath the body of the device and one foot will always be in an operative position to initiate walking motion when the device is again moved into contact with a walking surface.

Movement limiting means 80 are provided for limiting the movement of the legs in a clockwise direction as seen in FIGS. l2, 13 when a doll containing the walking mechanism of said figures is placed in a seated position.

As previously described, the Walking-seating mechanism of the present invention includes means for equalizing the length of the legs when a doll is seated by moving 7 the pins supporting said legs into generally vertical alignment (FIG. 5).

In the forms of the invention illustrated in FIGS. 3 through 11, a notch (such as 37) in the forward surface of one of the leg structures allowed the other leg structure to contact a movement limiting member before the notched leg thereby cranking the notched leg upwardly and evening the length of the legs.

In the form of the invention illustrated in FIG. 12, the same result is accomplished by making the shoulder 81 of one of members 80 lower than the shoulder 82 on the other member 80. Thus, leg 72 will contact shoulder 81 before leg 71 contacts shoulder 82 when a doll is seated and the pins supporting legs 71 and 72 will be cranked into generally vertical alignment with the pin supporting leg 71 uppermost.

FIG. 13 illustrates how the leg structure in the present walking-seating mechanism can be moved independently of each other to perform limited acrobatics. By applying extra force to the leg 72 which is in frictional contact with a floor, the opposed leg 71 can be moved forward with extra speed and since the camming surface 7 6 thereof is free for disengagement from camming member 75 the leg 71 can generate sufficient momentum to swing forward and simulate a kick or dance step. It should also be obvious that as a doll incorporating the present walking mechanism is propelled at a faster than normal speed, the leading leg will kick forward somewhat lengthening the stride just as in a human stride at a faster pace.

It should also be understood that the configuration of camming member 75 can be in various forms. In FIG. 14 an equivalent of camming member 75 is illustrated at 83 and is formed integrally with the leg carrying member 84.

Carnming member 83 may provide more than one point of contact for the camming surface 85 of a leg structure 86. The solid line representation of leg structure 86 illustrates contact between the upper extremity of said leg and camming member 83. The dot-dash line position 89 illustrates the contact between camming member 83 and the camming surface 85 of leg 86 with said leg near its forwardmost position.

Variations in the configuration of its camming member 83 can be used to produce irregular motions in the leg movement of a doll. The particular form illustrated in FIG. 14 may provide particularly good results where a kicking motion is desired.
