Abstract
SOFT PROPELLABLE TOY
ABSTRACT OF THE DISCLOSURE
An easily propellable toy constructed substantially of a soft, compressible, resilient material such as polyurethane foam or other foam rubber-like material, wherein the resiliency of the material is captured and converted to rotational motion which moves the toy. A compression plate on the top portion of the toy is depressed by the child playing with the toy, causing compression of the foam rubber body of the toy. When the compression plate is released, the natural resiliency of the foam material pushes the compression plate up, simultaneously causing linear movement of an elongate member which is attached to the underside of the compression plate.
This linear movement of the elongate member is converted, by means of a gear train, to rotational movement which is then communicated to the wheels of the toy.

SOFT PROPELhABLE TOY
BACKGROUND OF INVENTION
Field of Invention:
This invention pertains to propellable toys;
that is, toys which will move after some input of energy by the child playing with the toy. More specifically, this invention pertains to a toy intended for use primarily by children of preschool age, although the inventive concepts claimed herein may be used in toys for older children.
Description of the Prior Art.
Toys for the play and enjoyment of small children are as old in the art as man. Surely, one of the first things early mother wanted was something to amuse her small child. CountIess varieties of what have come to be referred to as "Preschool Toys" have been designed and developed. Preschool toys are typically intended for children of age 6 and less and are generally considered to be a separate classifica-tion of toys. These preschool toys can be broadlyclassified into three categories: firstly, toys that are designed for operation by an adult for the amusement of the child; secondly, toys that are designed for operation by the child himself; and thirdly, toys that are designed for adult/child cooperative operation.
Because the child at this age has undeveloped coordination and manual dexterity, such preschool toys of the second category must be designed for simple operation. Additionally, toys of this type must be designed to be as safe as possible, not only for the child playing with the toy, but for other children who .,, -. ~
~261~5f~
may be in the vicinity, and for furniture and other objects which may be in the play area. For these reasons, preschool toys are often constructed of soft material such as the toy shown in Manning, U.S. Patent No. 3,83S,583.
Still, any preschool toy must be sufficiently "fun" to first attract, and then retain the attention of a preshool youngster, whose attention span may be quite short and volatile. For this reason, toys that "do" something are preferable. The thing that most preschool toys of this type do, is move. A favorite type of toy is the vehicle or animal that has wheels.
Movement of the toy can be accomplished in a great many ways. A toy can be moved by the application of external force, such as a toy vehicle which is simply shoved along the ground by an adult or the infant himself. Other toys can be made self-propelled by the use of batteries, fuel or other power source. Still another method for moving the toy is by utilization of an internal windup mechanism, or something of that type.
Each of these types of toys have heretofore been subject to one or more drawbacks.
The toy which must be pushed or shoved along the ground typically does not prove to be a sufficient attraction to the child, and the child could quickly lose his interest in such a toy. This is a major drawback for a toy which cannot retain the attention of a child is no toy at all. The electrical or fuel-driven type toy is not well suited for preshool children for safety reasons. Lastly, the windup type toys are generally not suited for preshool because the windup mechanisms are not suited to the capabilities of a high number of preshool children. If a toy cannot be easily operated by the child, many children ~ 5~
become frustrated and upset. This, of course, is undesirable, as a toy is to entertain the child, not upset him.
Therefore there exists a need in the art for a toy which will provide to the child maximum pleasure while demanding no greater physical dexterity than a typical preshool child is likely to possess.
SUMMARY OF INVENTION
This invention provides such a toy which overcomes the deficiencies of the prior art in a wheeled toy which moves without fuel, batteries, motors, springs or windup mechanism. The toy is substantially constructed of a soft, compressible, resilient material preferably, polyurethane or a foam rubber like material. The exterior of the material is sculpted to the desired exterior shape of the toy and can be made to resemble a truck, van or other vehicle, the shape of an animal, fish or bird, or any other number of shapes. The compressibility and resiliency of this material is captured to provide a motive force for the toy. The child playing with the toy simply presses down on a conveniently located compression plate thereby causing some compression of the resilient material. When the compression plate is released, the inherent "memory" of the material causes it to resume its oriyinal shape. In so doing, it moves the compression plate back to its original position. This movement of the compression plate back to its original position is captured by gear means and communicated to wheels or other transportation means which are journaled to the body of the toy.
Pushing down on the compression plate is a simple movement involving only the major muscle ~2 6 ~
groups, which can typically be performed by a preshool age child. Once the compression plate is depressed and released, the vehicle zooms off at a rapid rate under its own power, to the continued delight of the 5 child.
The soft exterior of the toy provides increased protection from injury to the child playing with the toy, to any other children in the area, and also to furniture and other items which might be struck by the toy.
It is therefore the object of this invention to provide an improved toy which utilizes the compressibility and resiliency of the body material of the toy to provide the motive means for the toy, which toy is designed to the physical dexterity of the preshool child, and provides a soft exterior for the protection of the child and other children and objects in the play area.

DESCRIPTION OF THE PREFERRED EMBODIMENT
The preferred embodiment of this toy is depicted in the shape of a van or panel truck. It will be understood that the invention herein described and claimed has utility in a great number of different sizes and shapes of toy and is not therefore limited to this preferred embodiment.
As preferably embodied, the toy is generally of two-part construction, the first part being the body 10 and the second part being the chassis of the toy, generally designated 12.
The body 10 i5 constructed from a single piece of polyurethane foam material, having high resiliency and high density, preferably three and ; one~half pounds per cubic foot. This type material is available from a number of commercial sources. Other polyurethane, polymer, rubber or foam rubber-like material may be used. The body 10 is formed to the desired exterior shape of the resultant toy by molding, foamed in place process, die cut, or other process. In this preferred embodiment, a van or panel ,.. .
~2 6 ~S~
truck is shown. It will be understood that just as easily, a different vehicle such as a car, boatl or airplane could be depicted, as could any number of ani~als. In this preferred embodiment, the body 10 i5 approximately five inches high, four inches wide, and six inches long. A hollow chamber is formed in body 10 to accommodate therein various components of the chassis 12.
The chassis 12 has a base plate 14. The base plate can be made of any rigid durable material such as hard plastic or metal. Base plate 14 is nearly as large as the bottom of body 10, for reasons which will become apparent later herein~ Journaled to base plate 14 is front axle 16 and rear axle 18. In this embodiment, axles 16 and 18 are metal shafts which extend through appropriately sized apertures in journal boxes 20 and 22 which are attached to base plate 14 by any conventional means. On front axle 16, spacers 24 and 26, which can be constructed of plastic tubing, are placed, along with washers 28 and 30 to keep the axle centrally located within journal box 20. Front wheels 32 and 34 are attached to axle 16 by conventional meansO Rear wheels 36 and 38 are attached to rear axle 18 by conventional means. A
tread 40 may be provided on wheels 36 and 38 to provide better traction.
Attached to base plate 14 by conventional means is a gear box 42. Gear box 42 houses a gear train consisting of several intermeshing gear 30 wheels. The first gear wheel 44 meshes with a clutch gear 46. Clutch gear 46 is journaled in a slot 48 in the gear box such that the position of clutch gear 46 can change. Clutch gear 46, when it is in the down position in slot 48, engages second gear wheel 50.
35 When clutch gear 46 is in the upward position in slot ~Z 6 ~54 48, it will not engage gear wheel 50. Clutch gear 46 and second gear wheel 50 are two-stage gear wheels, having a first stage of smaller diameter, and a second stage of larger diameter. Gear wheel 44 acts upon the smaller first stage of clutch gear 46 while the larger second stage of clutch gear 46 acts upon the smaller first stage of gear wheel 50. The larger second stage of gear wheel 50 in turn acts upon axle gear 52 which is fixably attached to rear axle 18 within gear box 42. Axle gear 52 also acts to centralize axle 18.
A channel 54 is formed in gear box 42. The channel is perpendicular to base plate 14 and adjacent to first gear wheel 44. The channel 54 has an open end at the top of gear box 42.
An elongate member 56 is slidable within channel 54 between a fully extended position within gear box 42 (as shown in FIGURE 4) and a fully retracted position within gear box 42 (as shown in shadow in FIGURE 4). Elongate member 56 is of 20 sufficient length such that when it is in the fully extended position it reaches very nearly to the top of body 10 and still has a substantial portion which resides within channel 54 within gear box 42 at least as far as first gear 44. On the side of elongate 25 member 56 adjacent to first year wheel 44, a rack gear 58 is formed, or attached by conventional means. Rack gear 58 meshes with first gear wheel 44 such that as elongate member 56 is pushed downward within channel 54, rack gear 58 engages gear wheel 44 and turns it in 30 a counterclockwise direction (as seen in FIGURE 4).
This movement of gear wheel 44 causes clutch gear 46 to move upwardly within slot 48 out of engagement with second gear wheel 50. As elongate member 56 is moved from its fully retracted position upwardly in channel 35 54 to its fully extended position, rack gear 58 causes , .
~26~54 gear wheel 44 to move in a clockwise position. This movement of gear wheel 44 acts upon clutch gear 46 drawing it downwardly within slot 48 into engagement with second gear wheel 50. Accordingly, the upward linear motion of elongate member 56 is converted by the action of rack gear 58 on first gear wheel 44 into clockwise rotational movement of gear wheel 44, which causes clutch gear 46 to rotate in a counterclockwise position, which, in turn, causes second gear wheel 50 to rotate in a counterclockwise direction, and finally, causes axle gear 52 and hence the wheels to rotate in a counterclockwise direction, moving the toy in a forward direction.
Attached to the top of elongate member 56 is a compression plate 60. Compression plate 60 is disc-shaped, and is preferably constructed of any semi-rigid, durable material, such as plastic.
Compression plate 60 may be attached to elongate member 56 by any conventional means. Here, a plug 62 is placed in the end of elongate member 56 and compression plate 60 is attached thereto by screw means 64.
Compression plate 60 is of a sufficient size such that when it is pressed against the top of body 10, it causes a substantial compression of the body 10 material.
The elongate member 56 is retained within channel 54 by means of slot 66 in gear box 42 adjacent to channel 54, and a peg 68 attached to elongate member 56, which peg extends through slot 66. This peg 68 retains elongate member 56 in channel 54.
As constructed thusly, when the body material 10 is in the uncompressed state, the elongate member 56 is held in the fully extended position within channel 54 by means of compression plate 60 which '': '' . , ~26~L5~
rests against the top of the body material 10. When the child playing with the toy presses down on compression plate 60, elongate member 56 is forced downwardly in channel 54 to its fully retracted position. As rack gear 58 on elongate member 56 engages first gear wheel 44 during this downward thrust, gear wheel 44 is turned in a counterclockwise direction. This lifts clutch gear 46 upwardly in slot 48 out of engagement with second gear wheel 50, so that the rotational motion of gear wheel 44 is not communicated to gear wheel 50. Once the elongate member is pushed to its fully retracted position and compression plate 60 is released, the natural resiliency of the body material 10 pushes against compression plate 60 returning it to its original position as the body material 10 returns to its natural form. As compression plate 60 is pushed upwardly, it pulls with it elongate member 56 bringing it again to its fully extended position. During this upward thrust o~ elongate member 56, rack gear 58 acts upon first gear wheel 44 to turn it in a clockwise position. This clockwise rotation of gear wheel 44 acts upon clutch gear 46, pulling it downwardly in slot 48, into engagement with second gear wheel 50.
~ear wheel 50 is caused to rotate in a clockwise direction which causes axle gear 52, and hence the wheels, to also rotate in a counterclockwise direction moving the toy forward.
Although a preferred embodiment has been specifically described herein and depicted in the figures, it will be understood that those in the art that the inventive concepts embodied in this invention, and hereinafter claimed, are susceptible to many alternative embodiments and modifications.
~,26~5~
Accordingly, the invention is not to be limited ~o the specific embodiment set forth and depicted above, but is of the full breadth and scope of the appended claims.
