Goldfarb, 7427 Varna St., North Hollywood, Calif. Filed Nov. 12, 1963, Ser. No. 322,644 13 Claims. (Cl. 46-103) In general, the present invention involves a simply constructed and operated movable toy adapted to propel an object. More specifically, it involves a rmovable toy adapted to improve a childs coordination during solitary play, while sustaining interest with constant action, but without requiring substantial skill or excessive activity on the part of the child.

A wide variety of movable toys have been produced by the prior art and, in addition, a considerable number of toys have been adapted to propel an object. However, the movable toy, while incorporating the constant activity which maintains the childs interest, also usually involves excessive activity on the part or" the child in order to keep up with the toy,`so that the child soon becomes physically tired. On the other hand, the usual object propelling toy requires considerable skill on `the part of the child, such as the skill of throwing or rolling a ball into an opening spaced a considerable distance away from the child. Such capability is beyond the usual capability of small children, such as children in the age range of about 3-5, so that they usually require the help of a parent in playing with such toy and rapidly lose interest in the toy because of the frustration involved therein. In addition, the usual movable toy or object propelling toy of the prior art normally involved comparatively complicated structures requiring batteries or, at the very least, winding the toy which is also beyond the capability of small children. Also, such relatively complicated structures are particularly vulnerable to the well-known destructive capacity of small children. Also, the usual prior art windup toy lacked versatility. Thus, for example, it could not be used as a pull' toy, since it was not free-wheeling.

Consequently, a general object of the present invention is a simply constructed and operated movable toy which is adapted to propel an object.

Another object of the present invention is a self-returning movable toy which is wound up by the child rolling the toy away from him and then having a resultant move- :ment back toward the child. Also, if desired, the child can use the toy as a pull toy.

Another object of the present invention is a toy having a propelling means adapted to be cocked by placing of an object by the child on the toy body and to eject the object toward the child when the propelling means is released.

Still another object of the present invention is an object propelling movable toy which is self-returning and which projects the object back toward the child when the child rolls the toy away from him.

Other objects and advantages of the present invention will be readily apparent from the following description and drawings which illustrate a preferred exemplary embodiment of the present invention.

In general, the present invention involves an object pro- \pel1ing movable toy having a body including rolling means for facilitating easy movement of said toy across a supporting surface. Mounted on said body is a propelling means for projecting an object placed on said body and a power means for moving said toy which is charged by rotating said rolling means in a first direction. Also mounted on said body is a trigger means for releasing said propelling means, with the trigger means being actuated by the power means when a set level of poweris reached p during the charging.

In order to facilitate understanding of the present invention, reference will now be made to the appended drawings of a preferred specific embodiment of the present invention. Such drawings should not be construed as limiting the invention which is properly set forth in the appended claims.

In the drawings:

FIG. 5 is a perspective view with the hollow container` portion of the invention removed.

FIG. 6 is a cross-sectional view of a portion of FIG. 4 taken along line 5*6 of FIG. 4.

As illustrated in FIGS. 1 5, the present invention involves a toy 10 having a body 11 including rolling means 30 for facilitating easy movement of the toy across a supporting surface. pelling means 40 for ejecting an object 41, such as a ball, placed in the mouth.21 of the body 11. When the rolling means 30 is rotated in a lirst direction, i.e., the toy 10 is rolled backwards, the power means 60 mounted on the body 11 is charged. When a set level of power is reached during charging, a trigger means 70 mounted on the body 11 is activated by the power means 60 to release the propelling means 40.

The body 11 includes a platform 12 having upwardly extendingside flanges 13. Mounted on the platform 12 is a hollow container 14 formed to simulate the appearance of a living character, i.e., a turtle. The hollow container 14 includes a lower shell 15 riveted to the platform 12. Mounted on the lower shell 15 is an upper shell 16 and freely pivoted on the rear portion of the lower shell 15 is a tail 17. Between the lower and

upper shells

15 and 16 are freely pivoted feet 18. The body 11 also includes a head 20 having a forwardly opened mouth 21 which is adapted to receive and aim the object 41. The head 20 includes a lower jaw 22 formed as an extension of the lower shell 15 and having a tongue 23 attached to its front portion. Attached to the upper portion of the jaw 22 is the upper head portion 24 which includes an extension 25 adapted to form in conjunction with the lower jaw 22 the receiving pocket 26 for the object 41. The extension 25 has a slot 27 therein through which extends the prong 47 of the propelling means 40 so that the object 41 is seated thereon when received in the pocket 26.

The body 11 also includes rolling means 30 which are adapted to facilitate easy movement of the toy 10 across the supporting surface. The rolling means 30 include a front axle 31 slidably received in aligned holes 32 in the side flanges 13 of the platform 12. Rotatably mounted on each end of the axle 31 are front wheels 33 which are adapted to Contact the supporting surface for the toy 10. The rolling means 30 also :includes a rear axle 35 which is rotatably mounted in aligned holes 36 in the side flanges 13 of the platform 12. Preferably, the rear axle 35 hasa square cross-section, as illustrated, in order to facilitate fixedly mounting parts thereon. Fixedly mounted on .the rear axle 35 are rear wheels 37 which contact the supporting surface for the toy and have circumferential rubber treads 38 to increase the friction of the rear wheels 37 with the supporting surface. The rubber treads 38 may be simply formed by a rubber band stretched around the wheel 37 and received with the ends tucked in a slot 39 in the wheel 37.

Mounted on the body 11 are propelling means 40 for Mounted on the body 11 is a proejecting an object 41, such as a ball, placed in the pocket 26 of the body 11. The propelling means itl are adapted to be cocked by the placement of the ball 41 by the child in the pocket 26 of the mouth 21 and to eject the ball 41 toward the child when released. The propelling means 46 including a throwing lever 42 pivotally mounted on a bar 43 supported by an upright housing 44 mounted on the platform 12. The housing 46 has a front slot 45 through which the front arm 46 of the throwing lever 42 extends. The front arm 460i the throwing lever li2 has a prong 47 which extends through the slot 27 of the extension 25 of the upper head 24 and against which the ball 41 is seated. The front arm 46 of the throwing lever 42 also has a lip i8 onto which the trigger' means 7? is hooked.` The rear arm of the throwing lever i2 has a hole 51 to which one end of the lever spring means 52 is attached. The lever spring means 52" is formed from a coil spring 53 which has its other end attached to the body 11 by means of holes 19 in the platform 12. Fl`he lever spring means 52 is adapted to store energy, i.e., be placed under tension by the rotation of the throwing lever 42 caused by the insertion of the ball i1 into the pocket 26.

The power means 619 for moving the toy 14D are mounted on the body 11 and charged by rotating the rolling means 30. Thus, by rolling the toy 1t) away from the child on the supporting surface,'the power means 66 are charged and are adapted to move the toy 16 toward the child whereby .the toy is made self-returning. The power means 60 include a drive spring means 61 and a clutch means 65 for connecting the drive spring means 61 to the rolling means 36 during rotation of the rolling means 31B when the toy 1t) is rolled away from the child and for permitting disconnection of the drive spring means 61 from the rolling means 30 during the rotation of the rolling means 3i) when the toy 16 rolls toward the child. The drive spring means 61 include a coil spring 62 rotatably mounted on the rear axle 35 and having a iirst hook 63l formed at its iirst end and a second hook 64 formed at its second end. The clutch means 65 comprises a cam gear 66 fixedly attached to the rear axle 35 and having two sloping tracks 67 each of which terminate in a shoulder 68. When the rear wheels 37 are rotated by moving the toy in a rear direction, the rst hook 63 of the coil spring 62 slides on one of the tracks 67 until it engages one of the should-ers 68. Further rotation of the wheel 37 w-inds the coil spring 62 subjecting it to tension. On the other hand, when the toy 1t) moves in a forward direction, the first hook 63 of the coil 62 simply slides on the tracks 67 so that the wheel 37 is free-wheeling.

Also mounted on the body 11 is a trigger means 76 for releasing, the propelling means 40 with the trigger means 70`being actuated by the power means 60 when a set level of power is reached during charging, i.e., during rolling of the toy 10 in a rearward direction. The trigger means 70 includes a latching bar 71 pivotally mounted on the front axle 31 and adapted to releasably hold the propelling means 40 in a cocked position. Speciiically, the front arm 72 of the latching bar 71 has a hook 73 which catches onto the lip 48 of the throwing lever 42. Attached between the latching bar 71 and the body 11 is a latching spring 75. The latching spring 78 is connected at one end to a hole 7 6 in the rear arm 77 of the latching bar 71 and attached at the other end to holes 19' in the platform 12. The latching spring 78 is adapted to maintain the latching bar '71 in its holding position, i.e., with the hook 73 engaged with the lip 48 of the throwing lever 42.

Pivotally mounted on the rear axle 35 is a trip bar 80 which operatively connects the power means 60 and the latching bar 71. The trip bar S0 is adapted to oppose the action of the latching spring 75 on the latching bar 71 with the force exerted on the trip bar 80 by the power means 60. The trip bar 8l) has a front arm 81 with an inwardly extending boss 32 which extends parallel to the rear axle 35 and below the rear arm '77 of the latching bar 71. The trip bar Si) also has a rear arm 83 having an inwardly extending boss 84 with which the second hook 64 of the'coil spring 62 can become releasably engaged. Thus, during the rearward movement of the toy 10, the rotation of the wheel 37 causes the hook 64 to become engaged with the boss S4 of the trip bar 80. As the winding tension increases in the coil spring 62, a cord responding torque is exerted on the trip bar Si) which transmits said torque to the latching bar 71. Such torque when applied to the latching bar 71 would cause the hook 73 to disengage from the lip 48 of the throwing lever 42 except that i-t is overcome by the countervailing force of the latching spring 78. However, during the course of the rearward movement of the Itoy 16 a point is usually reached where suiicientenergy is charged, i.e., the unwinding tension of the spring becomes sufficiently great so that the tordue applied by the trip bar 80 overcomes the tension of latching spring means 7S and the throwing V lever 6i2 is released.

the toy 10 rolls away from the child, one ofthe shouldersV As set forth above, the operation of the toy is purposely very simple. Thus, a child need merely insert the ball 41 manually into the mouth 21 of the toy 10. As the ball 41 is received in the pocket 26 of the mouth 21 it depresses the prong 47 of the throwing lever 42 so that the lip 45S becomes engaged with the hook 73 of the latching bar 71. Such cocked posi-tion is maintained by the latching spring means 78. The child then merely rolls the toy 10 away from him with the head 26 facing toward the child. As

68 of the cam gear 66 is engaged by the rst hook 63 of the coil spring 62 andthe coil spring 62 begins to wind up, exerting a countertorque tothe torque impressed on the wheels 37 by the child rolling the toy 10 away from him. The coil spring 62 is wound by the rotation of its hook end 63 by the cam gear 66 because the second hook end 6ft. engages the lug 84 on the trip bar 80 and the lug 82 on the front part S1 of the trip bar is then braced against the'rear arm 77 of the latching bar 71. As the spring 62 builds up winding tension, a correspondingly great leverage is exerted on the reararm 77 of the latching bar 71, `tending to counteract the force exerted by the latching spring 75. At a given point set by the tension or" the latching spring '75, the force exerted by the winding tension of the spring 62 exceeds the latching spring 75 tension so that the hook 73 of the latching bar 71 is disengaged from the lip 4S of the throwing lever 42. When this occurs, the tension on the lever spring 53 and the leverage exerted by the short arm length of the rear arm 56 of the throwing lever l2 causes the ball 41 to be forceably ejected from the pocket 26 and propelled through the air toward the child. The toy 10 is designed so that the force of the ejection, coupled with the aiming of the coniiguration of the pocket 26 is designed to reach the child operating the toy on a substantially horizontal trajectory at the level of about v2 to 3 feet under normal operating conditions. After the release of the propelling means 40 Ior possibly before or concurrently therewith, the Winding tension on the spring 62 exerts suiiicient force to overcome the impulse imparted to the toy by the child when he initially rolls the -toy away from him. At such point, the toy 1@ stops and the energy charged in the spring 62 is then exerted on the shoulder 68 of the cam gear 66 which in turn is translated to the rear wheels 37. The toy 16 then begins to move rapidly toward the child operating the toy. However, the force exerted on the toy 11i by the wound-up spring 62 is soon discharged, leaving the toy with considerable momentum. Under such conditions, the cam gea-r 66 continues to rotate as the toy rolls toward the child, but the hook 63 becomes disengaged from the shoulder 68 and continues to ride on the tracks 67 so that the toy becomes free-wheeling. In this Way, the spring 62 is prevented from acting as a brake as the toy 19 moves toward the child. Thus, if desired, the child, when tired-of playing catch with the toy, can use the toy as a pull toy by pulling the cord.

. Many other specific embodiments of the present invention will be obvious to one skilled in the art in view of this disclosure. For example, although both of the rear wheels are fixed to the rear axle, only one of such wheels needs to be fixed to insure movement `of the toy. Similarly, although the drive spring means is free to rotate at least at one end and free, to a limited extent at the other end, it may be completely fixed at one end. In addition, although a specific structure for propelling `means and trigger means has been set forth, other alternative constructions may be utilized which function in a similar manner.

There are many features in the present invention which clearly show the significant advance the present invention represents over the prior art. Consequently, only a few of the more outstanding features will be Vpointed out to illustrate the unexpected and unusual results attained by the present invention. One feature of the present invention is a simply constructed and operable movable toy which is adapted to improve the childs coordination during solitary play while sustaining interest with constant action, but without requiring substantial skill or ,excessive activity on the part of the child. Thus, the only skill required is the skill involved incatching a ball which is constantly thrown on a substantially horizontal path when reaching the child at substantially the same height which is much simpler than trying `to throw the ball into an opening spaced a distance away.V Fur-ther, the child starts to play by manually inserting the ball into the mouth of the toy and rolling the toy away from him, both of which require very simple skills.` In addition, the toy is selfreturning so that although the child gets the throwing activity and the constant action of the toy to maintain interest, he does not indulge in the excessive activity of constantly running, as normally involved in most moving toys. Another feature of the present invention is the utilization of the rolling motion by the child to wind the toy which eliminates expensive auxiliary power means, such as batteries, -or the more complicated arrangement involving winding up manually by keys. Still another feature of the present invention is the utilization of the energy storage function to actuate the ball propelling means of the toy so that the projection of the ball toward the child is delayed until the toy is rolled a substantial distance from the child. Still another Vfeature of the present invention is an efficient energy storing and dispensing means so that the winding up of the toy caused by rolling the toy away from the child is effectively utilized to return the toy to the child and the power means is effectively disengaged when the toy attains such return momentum so that no braking action occurs.

Still another feature ofthe present invention is a versatile toy which can be used either as a wind-up toy or a pull toy.

It will be understood that the foregoing description and examples are only illustrative of the present invention and it is not intended that the invention be limited thereto.
