Abstract
A toy for amusing people of all ages by flipping along a surface. The rolling toy includes a cylindrical tube having a first sealed end and a second sealed end and a weighted ball enclosed within the cylindrical shaped tube and having a circumference smaller than a circumference of said cylindrical tube allowing said weighted ball to roll along a length of said cylindrical tube. A flexible body portion is secured to the first sealed end of the cylindrical tube and a spring extends through the body portion. The body portion able to maintain the rolling toy in an upright position with the cylindrical tube positioned atop the body portion. When the cylindrical tube is tiled, the weighted ball is caused to roll along the length of the cylindrical tube from the first end to the second end. This causes the cylindrical tube to move towards the surface, the body portion to bend as the cylindrical tube moves towards the surface and the spring to uncoil. Upon the cylindrical tube contacting the surface, the weighted ball contacts the second surface and the spring begins to recoil causing the body portion to flip over the head portion. Momentum of the body portion rotates the head portion and the body portion to return to an upright position. The spring is preferably connected between an end of the body portion opposite the cylindrical tube and the weighted ball.

2. Description of the Prior Art




Numerous self-righting toys have been provided in prior art. For example, U.S. Pat. No. 2,585,780 to Johnson; U.S. Pat. No. 2,942,379 to Oman et al.; U.S. Pat. No. 3,805,444 to Adickes and U.S. Pat. No. 4,411,096 to Smith all are illustrative of such prior art. While these units may be suitable for the particular purpose to which they address, they would not be as suitable for the purposes of the present invention as heretofore described.




U.S. Pat. No. 2,585,780




Issued: Feb. 12, 1952




Inventor: Keith Whitaker Johnson




A toy comprising a tube of relatively light weight. Two outwardly convex caps of substantially equal diameter and of relatively light weight closes respectively the opposite two ends of the tube and extends laterally and rearwardly therefrom. The inner surfaces of the caps and the bore of the tube form a tubular chamber. A relatively heavy ball enclosed within the tubular chamber provides a toy adapted to balance upon one of the outwardly convex caps when placed upon a level supporting surface. The tube increases in bore diameter toward at least one end from any point along its length other than the last mentioned end. When the longitudinal axis of the tube is substantially horizontal, the gradient of the lower inner surface of the tube will cause the ball to roll to and come to rest in the last mentioned end of the tube, whereby the weight of the ball will cause the toy to rise to a substantially upright position upon the outwardly convex cap at the end containing the ball.




U.S. Pat. No. 2,942,379




Issued: Jun. 28, 1960




Inventor: Richard W. Oman et al.




A toy comprising a rockable body including a base having a convexly contoured under surface. A partition carried by the base is in position for viewing from a position above the base. The partition has fixedly positioned thereon formations which are positioned relative to one another, so as to present a variable picture image when seen from different angles. A weight is located in the base in a plane which includes a line extending perpendicularly through the center of the partition and has an arcuate line of intersection with the under surface. The weight is located below the partition and in spaced lateral relation from the line extending perpendicularly to the partition to thereby locate the center of gravity of the body, so as to position the partition at an angle with respect to the vertical when the body is at rest. Rocking motion of the body relative to its position of rest will result in a change in the angle of view with respect to the formations with consequent different visual images being produced.




U.S. Pat. No. 3,805,444




Issued: Apr. 23, 1974




Inventor: Cecil F. Adickes




A toy article having a body formed in an egg-like configuration and defined by a base portion in which a weight is located. A central portion having a preselected design is formed thereon. A top portion having a downwardly extending shaft joined thereto engages the base portion for securing the body portions together in a unitary construction. The weight in the base portion cooperating with a rounded bottom wall thereof is to insure that the body will always return to an upright position regardless of exterior forces applied thereto.




U.S. Pat. No. 4,411,096




Issued: Oct. 25, 1983




Inventor: Samuel C. Smith




There is disclosed in the present application a toy in the form of a doll or statue representing a human figure, including a body and a head which is completely separable from the body. The head is contoured and balanced in such a way that when displaced downwardly from its normal at rest position atop the body, it rolls back upwardly to its normal position, seemingly in defiance of gravity. The movement of the head toward its normal position is accomplished by one or more weights embedded in the head, which provide the necessary torque to cause it to move upwardly to its position on the shoulders.




SUMMARY OF THE INVENTION




The present invention relates generally to toys and, more specifically, to a rolling toy including a lightweight hollow cylindrical shaped head having a moveable weighted ball therein attached to a flat flexible body including a spring extending therethrough causing the toy to complete a flip when the head falls forward.




A primary object of the present invention is to provide a rolling toy that will overcome the shortcomings of the prior art devices.




Another object of the present invention is to provide a rolling toy able to flip a body section thereof in the manner of a summersault when the head portion is caused to fall forward.




A further object of the present invention is to provide a rolling toy including a lightweight hollow cylindrical shaped head having a moveable weighted ball therein whereby, when the head is allowed to fall forward, movement of the weighted ball therein causes the body to tumble over.




An even further object of the present invention is to provide a rolling toy including a spring extending through the body thereby aiding the body in flipping over when uncoiled by the falling over of the head.




A still further object of the present invention is to provide a rolling toy whereby the body is caused to do a back flip when the head is caused to fall backwards.




An even further object of the present invention is to provide a rolling toy able to entertain both children and adults.




A yet further object of the present invention is to provide a rolling toy that is simple and easy to use.




A still further object of the present invention is to provide a rolling toy that is economical in cost to manufacture.




Further objects of the invention will appear as the description proceeds.




A toy for amusing people of all ages by flipping along a surface is disclosed by the present invention. The rolling toy includes a cylindrical tube having a first sealed end and a second sealed end and a weighted ball enclosed within the cylindrical shaped tube and having a circumference smaller than a circumference of said cylindrical tube allowing said weighted ball to roll along a length of said cylindrical tube. A flexible body portion is secured to the first sealed end of the cylindrical tube and a spring extends through the body portion. The body portion able to maintain the rolling toy in an upright position with the cylindrical tube positioned atop the body portion. When the cylindrical tube is tiled, the weighted ball is caused to roll along the length of the cylindrical tube from the first end to the second end. This causes the cylindrical tube to move towards the surface, the body portion to bend as the cylindrical tube moves towards the surface and the spring to uncoil. Upon the cylindrical tube contacting the surface, the weighted ball contacts the second surface and the spring begins to recoil causing the body portion to flip over the head portion. Momentum of the body portion rotates the head portion and the body portion to return to an upright position. The spring is preferably connected between an end of the body portion opposite the cylindrical tube and the weighted ball.




To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated and described within the scope of the appended claims.

FIGS. 1 through 9

illustrate the rolling toy of the present invention indicated generally by the numeral


10


.




The rolling toy


10


of the present invention is illustrated in FIG.


1


. The rolling toy


10


includes a substantially flat flexible body portion


20


and a head portion


12


connected to a top side of the body portion


20


. The head portion


12


is preferably cylindrically shaped and hollow. The head portion


12


is also preferably closed on both ends with a bottom side sealed end


14


and a top side sealed end


16


. Sealed within the head portion


12


is a weighted ball


18


as is illustrated in phantom in FIG.


2


and discussed hereinbelow with specific reference to

FIGS. 7 and 8

. The weighted ball


18


is of a circumference slightly less than the inner circumference of the head portion


12


and is able to roll along the length of the cylindrical head portion


12


. The head portion


12


is formed of an elongate cylindrical tube


24


with the bottom side sealed end


14


closing one side thereof and the top side sealed end


16


closing the opposing side thereof. On an outer side of the cylindrical tube


24


are ornaments representative of a face for the rolling toy


10


. These ornaments are for purposes of illustration only, adding to the appearance of the rolling toy, and not meant to limit the scope of the present invention. The ornaments shown include eyes


40


positioned adjacent the top of the cylindrical tube


24


, a nose


42


positioned below the eyes


40


and a mouth


44


positioned below the nose


42


providing the appearance of the face for the rolling toy


10


.




An enlarged cross-sectional view of the head portion


12


is illustrated in FIG.


7


. From this view it is seen that the cylindrical tube


24


forming the head portion


12


is hollow. The bottom side sealed end


14


closes off a bottom side of the cylindrical tube


24


and the top side sealed end


16


closes off a top side of the cylindrical tube


24


. The cylindrical tube


24


forming the head portion


12


is preferably fabricated out of any combination of a plastic material, cardboard material or any other light weight sturdy material able to retain the weighted ball


18


therein and withstand the pressure applied by the weighted ball


18


when rolling therein and impacting the bottom and top sealed ends


14


and


16


, respectively, thereof. Sealed within the cylindrical tube


24


is the weighted ball


18


. The circumference of the weighted ball


18


is smaller than the inner circumference of the cylindrical tube


24


as shown in

FIG. 8

thereby allowing the weighted ball


18


to roll within and along the length of the cylindrical tube


24


. The weighted ball


18


is preferably fabricated out of glass, steel or plastic. However, any suitable material able to be formed into a ball and having a weight able to cause the rolling toy


10

is the weighted ball


18


. The circumference


26


of the weighted ball


18


is shown to be slightly less than the inner circumference


28


of the inside of the cylindrical tube


24


. This allows the weighted ball


18


to roll along the length of the cylindrical tube


24


.




As illustrated in

FIG. 9

, the lightweight hollow cylindrical shaped head


12


can contain a dome shaped rounded crown


60


on the top side sealed end


16


. This dome


60


facilitates the tumbling of the rolling toy


10


down an inclined plane or even over a flat surface by decreasing the friction between the head portion and the surface on which the rolling toy


10


is flipping.




The body portion


20


is attached to the bottom side sealed end


14


of the head portion


12


. An exemplary body portion


20


is illustrated in FIG.


1


and throughout the drawings. This body portion


20


is illustrated for purposes of example only and not meant to limit the scope of the present invention. The flat flexible body


20


can be fabricated out of a thin sheet of plastic material, a thin sheet of cloth material


38


or any other material which is able to retain the rolling toy


10


in an upright position maintaining the heap portion


12


thereatop while also being bendable and stretchable. The body portion


20


is preferably shaped in the form of an animated object as shown in the figures including a simulated torso


46


, a pair of arms


48


with hands


50


and a pair of legs


52


with feet


54


. The feet


54


should be of a dimension able to provide a stand for retaining the rolling toy in an upright position. The shape of the body portion


20


is for purposes of illustration only, adding to the appearance of the rolling toy, and not meant to limit, the scope of the present invention. Positioned within the body portion


20


and shown in

FIGS. 2-4

and


9


is a spring


30


. The spring


30


is connected between the bottom sealed end


14


of the head portion


12


and a crotch or base area


32


of the body portion


20


. When the head portion


12


is caused to lean forward and fall towards the base of the body portion


20


the spring


30


is caused to uncoil as will be explained hereinafter. The spring


30


will recoil when the head portion


12


reaches a solid surface causing the body portion


20


to move with the spring


30


and complete a flip of the rolling toy


10


. The spring


30


may be secured to the weighted ball


18


and thus be caused to uncoil and recoil as the weighted ball rolls within the cylindrical tube


24


.





FIGS. 2

,


3


and


4


illustrate the bendable nature of the body portion


20


and the positions of the rolling toy


10


at different points during a flip thereof.

FIG. 2

illustrates a first position of the rolling toy


10


during a forward flipping thereof. In this position, the head portion


12


was caused to tilt forward in the direction of the arrow labeled with the reference numeral


34


. The movement of the head portion


12


in this manner causes the weighted ball


18


within the cylindrical tube


24


to roll to the top side of the cylindrical tube


24


and applies a force to both the top side sealed end


16


and the spring


30


. This force causes the head portion


12


to move towards the surface on which the rolling toy


10


is positioned and the spring


30


to uncoil. Upon the head portion


12


contacting a surface on which the rolling toy


10


is positioned, the spring


30


will be at its maximum extension point. At this time the spring


30


will attempt to recoil. As the spring


30


recoils, the connection of the spring


30


to the crotch area


32


of the body portion


20


will cause the body portion


20


to flip over the top of the head portion


12


in the direction of the arrow labeled with the reference numeral


36


.





FIG. 3

illustrates the position of the rolling toy


10


midway through a flip. At this point of the flip, the body portion


20


has swung over the top of the head portion


12


in the direction of the arrow labeled with the numeral


38


. In this position the back side of the body portion


20


is positioned on the surface on which the rolling toy


10


is positioned and the spring has moved into a recoiled position. The legs


52


and feet


54


of the body portion


20


will continue to rotate until they contact the surface. At this point, the weighted ball


18


shown in phantom has rotated to contact the bottom side sealed end


14


at the bottom of the cylindrical tube


24


. The momentum of the rolling toy


10


causes the head portion


12


to rotate as indicated by the arrow labeled with the numeral


56


to a position above the body portion


20


. At this point, the body portion


20


and spring


30


are bent.





FIG. 4

illustrates the end position of the rolling toy


10


upon completion of the flip. To complete the flip, the head portion continues its rotation as indicated by the arrow labeled


58


. As the head portion


12


continues to a position atop the body portion


20


, the body portion


20


and spring


30


will straighten out until the rolling toy


10


reaches a completely upright position as shown in the figure.




The operation of the rolling toy


10


will now be described with reference to the figures and specifically

FIGS. 5

,


6


and


9


. The movement of the weighted ball within the head portion will be described with specific reference to

FIGS. 5 and 9

and the action of the spring will be described with specific reference to FIG.


9


. In operation, the rolling toy


10


is positioned on a surface


22


. The figures illustrate the surface


22


as being inclined however, the surface may be flat as well. The advantages to placing the rolling toy


10


on an inclined surface is that no additional interaction is required to cause the rolling toy


10


to begin flipping beyond placement on the surface.




The rolling toy


10


is positioned on the surface


22


in an upright position, this position is the rightmost illustration in

FIGS. 5

,


6


and


9


. In this position, the body portion is extending perpendicular to the surface


22


and the weighted ball


18


is positioned against the bottom side sealed end


14


. When the rolling toy


10


is on a slanted surface


22


or the head portion


12


is caused to tilt forward, the weighted ball


18


within the cylindrical tube


24


is caused to roll towards the top side sealed end


16


of the cylindrical tube


24


. Movement of the weighted ball


18


causes the head portion to tilt further towards the surface


22


and the spring


30


to begin uncoiling. Movement of the weighted ball


18


within the cylindrical tube


24


slightly above the bottom side sealed end


14


is evident from the second illustration from the right of FIG.


5


and FIG.


9


. This force causes the head portion


12


to move further towards the surface on which the rolling toy


10


is positioned and the spring


30


to begin to uncoil. As the head portion tilts further, the weighted ball is caused to slide further along the length of the cylindrical tube


24


, pulling the spring


30


therewith as shown in the third illustration in

FIGS. 5 and 9

.




Upon the head portion


12


contacting a surface on which the rolling toy


10


is positioned, the weighted ball


18


will contact the top side sealed end


16


and the spring


30


will be at its maximum extension point. This is illustrated in the fourth illustration of

FIGS. 5 and 9

. The second illustration of

FIG. 6

shows the rolling toy


10


in this position. At this time the spring


30


will attempt to recoil. As the spring


30


recoils, the connection of the spring


30


to the crotch area


32


of the body portion


20


will cause the body portion


20


to flip over the top of the head portion


12


in the direction of the arrow labeled with the reference numeral


36


. This is shown in the fourth illustration of FIG.


9


. The position of the rolling toy


10


after the body portion


20


has flipped over the head portion is shown in the third illustration of FIG.


6


.




The leftmost illustration of

FIGS. 5

,


6


and


9


show the position of the rolling toy


10


upon completion of the flip. To complete the flip, the head portion continues its rotation as indicated by the arrow labeled


58


. As the head portion


12


continues to a position atop the body portion


20


, the body portion


20


and spring


30


will straighten out until the rolling toy


10


reaches a completely upright position as shown in the figure. At this point, the weighted ball


18


returns to its position contacting the bottom side sealed end


14


.




From the above description it can be seen that the rolling toy of the present invention is able to overcome the shortcomings of prior art devices by providing a rolling toy which is able to flip a body section thereof in the manner of a summersault when the head is caused to fall forward in a manner that is entertaining to both children and adults. The rolling toy includes a lightweight hollow cylindrical shaped head having a moveable weighted ball therein and a spring extending through the body thereby aiding the body in flipping over when uncoiled by the falling over of the head.
