4 Claims. (Cl. 4615i This invention generally relates to a toy and more specifically provides an animated toy which is motivated by a wound spring motor.

An object of the present invention is to provide an animated toy in the form of an insect or the like having six ground or surface engaging legs together with means for operating the legs for moving the toy in a forward or reverse direction.

Another object of the present invention is to provide an animated toy having a novel arrangement of moving legs wherein a plurality of legs are disposed on each side and when the toy is being driven, a majority of the legs on one side and a minority of the legs on the other side are moving in one direction while the other legs are moving in another direction for propelling the toy.

Other objects of the present invention will reside in its simplicity of construction, ease of operation, plurality of moving parts disposed externally of the body shell, adaptation for its particular purposes and its relatively inexpensive manufacturing cost.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a perspective View of, the animated toy of the present invention;

Figure 2 is a longitudinal, vertical sectional view taken substantially upon a plane passing along section line 2--2 of Figure 1 illustrating the details of construction of the drive mechanism;

Figure 3 is a plan view of the frame or platform with the driving mechanism attached thereto;

Figure 4 is a transverse, vertical sectional view taken substantially upon a plane passing along section line 4-4 of Figure 1 illustrating furt er details of the shifting mechanism for reversing the movement of the toy;

Figure 5 is a detailed perspective view illustrating the attachment of the inner ends of the legs to the crank arms or rods;

Figure 6 is a detailed perspective view similar to Figure 5 illustrating the members in assembled position; and

Figure 7 is a perspective view of one of the connecting rods or arms.

Referring now specifically to the drawings, the numeral 16 generally designates the animated toy of the present invention including a generally horizontally disposed platform or frame 12 which is substantially oval in shape in configuration as illustrated in Figure 3 to which is attached a hollow body member 14 that is substantially U-shaped in transverse configuration and inverted with the edges thereof secured to the edges of the frame 12 by the use of bendable tabs 16. The front of the body member 14 may be provided with simulated eyes 18 wherein the toy it? will simultate an insect.

Disposed adjacent each side edge of the frame 12 is an upstanding member 29 and these upstanding membets 2!) taper inwardly and rearwardly and generally conform to the contour of the frame 12. Each of the upstanding members 29 is provided with a plurality of longitudinally spaced apertures 22 in the form of horizontally disposed slots each receiving a horizontal extension 24 on an inverted V-shaped leg 26 which has one end thereof designated by the numeral 26 depending below the frame 12 for supporting the same from a supporting surface in spaced relation. As will be evident in Figure 3, as well as in Figure 1, three inverted V-shaped legs 24- are provided on each side of the toy is? and each of the legs 24 has a lateral horizontally disposed portion 23 slidably and pivotally disposed in the slots 22 in the upstanding member 29 wherein the legs may swing back and forth and up and down in accordance with a driving mechanism described hereinafter.

A pair of identical connecting rods or arms 28 are mounted on the frame 12 with one end thereof being slidably and pivotally received in transversely spaced apertures 36 in an upstanding lug 32 adjacent the rear of the frame 12. Adjacent the front of the frame 12 is a pair of upstanding bearing lugs 34 rotatably supporting a crankshaft 36 having a pair of oppositely disposed cranks 38 thereon and each of the connecting rods 28 is provided with a loop 4% at the forward end thereof for attachment to oppositely disposed cranks 38 on the crankshaft 36 wherein rotation of the crankshaft 36 will move the connecting rods or arms 23 in a manner well known wherein the loop end 42 will rotate with the cranks 38 while the free ends of the arms 23 will slide in pivot in the apertures 3% in the lug 32.

Each of the connecting rods or arms 28 is identical and includes a notched portion 42 in one side edge thereof and a lateral U-shaped extension 44 on the other side thereof. One of the connecting rods 28 is inverted in relation to the other wherein the U-shaped member is inverted while the other of the rods 28 has a U-shaped extension 44 facing upwardly with the bight portion of the U-shaped extension 4-4 in each bridging the adjacent connecting rod 28 at its recessed portion 42 substantially as illustrated in Figure 3. It will be noted that an aperture 56 is provided at each end of the recessed portion 42 and also on the end of the leg of the U-shaped member or extension 44.

As illustrated in Figures 5 and 6, each horizontal extension 23 on each of the legs 24 is provided with a depending tab 48 having a laterally extending end portion 5%) wherein the horizontal extension 23 may be tilted slightly and inserted in one of the apertures 46 after which the lateral extension 50 will retain the hori-' zontal extension 23 connected to one of the connecting rods 23 for both pivotal and limited rocking movement since the diameter of the aperture 46 is slightly larger than the width of the depending tab 48.

When the crankshaft 36 is rotated, the movement of the connecting arms 28 will be directly opposed to each other regardless of the direction of rotation of the crankshaft 36. The connecting rods 28 are provided with two legs 24 extending from the adjacent side of the frame and another leg 24 which is connected to the U-shaped member 44 extending from the opposite side of the frame i2 wherein the forward and rear leg on one side and the center .leg on the other .side is moving in one direction while the two legs on the other side and the center leg on the one side are moving in the opposite direction for moving the toy. It will be noted that the movement of the connecting r0ds28 also includes swinging movement in a vertical plane whereby the surface engaging ends 26 of the legs 24 will move vertically for permitting step-by-step motion of the body member 14 and the frame 12 in either longitudinal direction since the legs 24 having-the @free ends 26 movedownwardly'will support the toy'ltl while theiother' legs are moving forwardly in lifted position for the next step. -It will be note d that the body :member '14 is provided with a notched recess portion 52 for permitting swinging and oscillatory movement of the horizontal portions 23 of each leg 24.

For driving the crankshaft 36 in either direction, a gear '5 4 is provided on each end thereof wherein selective rotation of these gears will cause rotation of the crank'shaftin selective directions.

Forrotating the gears 54, a pivotally mounted gear carrier 56 is supported from depending pivot'lugs 53 in the top-of the body member 14. Mounted on a vertical shaft-6i isa horizontally disposed plate 62 having depending peripheral gear teeth 64 which will engage either of the gears 54 When the gear carrier 56 is tilted about the longitudinal axis formed by supporting pins 66. Also secured to the shaft 6i is a pinion gear 67 in meshing engagement with a large drive gear 63 which is driven by a spring mechanism 70 mounted on a vertical shaft 72 'which also supports the drive gear 68 in the gear carrier 56. The upper end of the vertical shaft 72 is provided with a polygonal extension 74 for receiving a winding key 76 wherein the spring 70 may be tensioned or wound in a manner will known for driving the drive gear 68 thereby rotating thepinion 56 and driving the plate gear .62.

For tilting the gear carrier 56 about a longitudinal axis, a pair of simulated feelers 76 are provided with each feeler having a cam 78 on the lower end which are disposed in angularly spaced relation for engagement with the top of the gear carrier 56 when the feelers 76 are in different angular position whereby forward movement of the feelers 76 'will engage the cam 78 with the gear carrier 56 for urging the gear carrier 56 about its longitudinal axis for bringing the gear 62 in engagement 7 V with one of the gears 54 for moving the toy forwardly while reverse movement of the feelers 76 will cause the gear carrier 56 to tilt to the other side thereby driving the toy v10 in a reverse direction.

Accordingly, it will 'be seen that a relatively simple reversing mechanism is employed for driving the legs wherein the legs actually simulate the action of an insect for stepsby-step motivation.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
