The handle is extendable for adjusting the length of the wheel-guiding device. The wheel's motion is controlled with the wheel-guiding device by engaging the U-shaped member and pushing on the wheel with the wheel-guiding device causing the wheel to both rotate and move in various directions or to stop movement of the wheel.

## Background
FIELD OF THE INVENTION
This invention relates generally to devices for use as an amusement or during physical exercise, and more specifically to devices for wheel guiding and methods for controlling wheel movement thereof.
BACKGROUND OF THE INVENTION
In the past, various distractions have been available for people seeking an amusement or wanting to exercise and maintain a degree of less boredom. For example, head set radios and CD players are both commonly used by walkers and joggers, and free these people from the routine involved in their exercise. People commonly play games such as football, baseball, tennis and racquetball for physical exercise.
Currently, most joggers, walkers and runners do not include games during their activity. As a result, motivation for performing their activity is weakened. People, rather than going along paths may use relatively expensive exercise machines. It is desirable to have less expensive devices for exercise purposes that will engage the interest of people. A portable exercise device that can be adjusted for use by children or adults of various heights is also desirable.
In addition, people do not take advantage of other possibilities such as improving their hand and eye coordination, while continuing to maintain their physical activity. While sports activities provide the advantage of hand and eye coordination, they also require a level of skill that reduces the desirability of some people to pursue those sports. Therefore, there is a need for a product that can amuse people and can help people with lower degrees of skill and the desire to exercise without using exercise machines to do so and develop their motor skills.
For many people, exercise is a boring activity that becomes a task rather than being fun. Again, a device that provides the ability to engage people in mentally challenging activities, provide fun and promote physical activity would be of great benefit to many people. Chasing a wheel provides such an activity.
For the foregoing reasons, there is a need to provide devices for wheel guiding and methods for controlling wheel movement thereof.
SUMMARY OF THE INVENTION
Accordingly, it is an object of this invention to provide improved devices for wheel guiding.
It is a further object of this invention to provide improving devices for wheel guiding that are adjustable in dimension for use by people of different heights.
It is a further object of this invention to provide improving methods for controlling wheel movement with wheel-guiding devices.

DESCRIPTION OF THE INVENTION
Referring to FIGS. 1, 4, 5, 6, 7 and 9 a wheel-guiding device 10 comprises a U-shaped frame 26 connected to a handle 22. The U-shaped frame 26 comprises a first member 28 essentially perpendicular to and adjacent to the handle 22 to form the first part of the U-shape. A second member 30 is adjacent to and co-planar with the first member 28, forming the second part of the U-shape. A third member 32 is adjacent to the second member 30 and co-planar with the first and second members 28, 30, forming the third part of the U-shape. While the length of the U-shape member 26 can be varied, in this embodiment a total length of about two feet is preferable.
According to FIG. 1, the handle 22 is at right angles to the U-shaped frame 26. However, the handle 22 may also be at a more acute or obtuse angle to the plane of the U-shaped frame 26. The term “essentially perpendicular” means that the handle 22 is at a right, acute or obtuse angle to the plane of the U-shaped frame 26, but not co-planar with U-shaped frame 26.
In FIGS. 1 and 2, in this embodiment, the handle 22 is extendable with an upper portion 20 of the handle 22 at an open end of the upper portion 20 of the handle 22 to allow for adjustment of the overall handle length for people of varying height. The upper portion 20 of the handle 22 has a moveable length adjustor 24 (FIG. 2) to stop the handle 22 at the appropriate length for the height of the person intending to use the wheel-guiding device 10. In addition, the upper portion 20 of the handle 22 has a knob 18 (FIGS. 1 and 2) that fits tightly over a closed end of the upper portion 20 of the handle 22 for gripping the wheel-guiding device 10. Therefore, the wheel-guiding device 10 is suitable for use by children and adults.
Referring to FIGS. 1 and 3, a hollow wheel 12 is shown surrounded by the U-shaped frame 26 between the frame members 28, 30 and 32. The diameter of the hollow wheel 12 may vary and is preferably about 1 foot in this embodiment. The hollow wheel 12 has an outer surface 14 and an inner surface 16. The hollow wheel 12 is caused to rotate in a forward motion by pushing the U-shaped frame 26 against the outer surface 14 of the hollow wheel 12 (FIG. 3). A person then continues to follow the motion of the hollow wheel 12 and apply a pushing force to continue its rotation.
FIG. 3 indicates potential directions of motion of the hollow wheel 12 when a member of the U-shaped frame 26 pushes the hollow wheel 12 on the outer surface 14 of the hollow wheel 12. The directions shown in FIG. 3 include straight, left, right or U-turns. In addition, circles can be made. These changes in motion are accomplished by manipulation of the hollow wheel 12 with the wheel-guiding device 10 on various parts of the hollow wheel 12, and by altering the angle at which the wheel-guiding device 10 meets the hollow wheel 12. The faster the wheel-guide device is used by following the hollow wheel 12, the quicker the hollow wheel 12 moves, increasing the rate of physical exercise. The wheel-guiding device 10 provides challenges for manipulation of the hollow wheel 12, while improving eye and hand co-ordination skills.
Referring to FIGS. 4, 5 and 6, alternative methods of manipulating the hollow wheel 12 illustrate how contact between a member of the U-shaped frame 26 and the outer surface 14 or the inner surface 16 of the hollow wheel 12 results in movement of the hollow wheel 12. In FIG. 4, the contact is between the first member 28 and the inner surface 16. In FIG. 5 the contact is between the first member 28 and the outer surface 14, and in FIG. 6 the contact is between the second member 30 and the inner surface 16. A pushing force of the handle 22 causes motion of the hollow wheel 12. For these embodiments, as shown in FIGS. 4, 5 and 6 contact is maintained between the hollow wheel 12 and the wheel-guiding device 10 during use, rather than allowing the hollow wheel 12 to move freely. An alternative embodiment of FIG. 4 allows for contact of the first member 28 at an edge of the inner surface 16 of the hollow wheel 12, rather than having the U-shaped frame 26 fully within the interior surface 16 of the hollow wheel 12. Similarly, an alternative embodiment of FIG. 5 allows for contact of the first member 28 at an outer edge 16 of the hollow wheel 12. In each case, the first member 28 (FIGS. 4 and 5) can be withdrawn from the edge of the inner surface 16 after each pushing motion, allowing the hollow wheel 12 to move freely.
Referring to FIGS. 7 and 8 motion of the hollow wheel 12 is stopped by contacting the outer surface 14 of the hollow wheel 12 with the second member 30 of the U-shaped frame 26. Greater control of the stopping motion is possible by contacting and surrounding the hollow wheel 12 between the members 28,30 and 32 of the U-shaped frame 26. Other methods of contact between the outer surface 14 of the hollow wheel 12 and the wheel-guiding device 10 for stopping motion of the hollow wheel 12 are possible.
In another embodiment of a method for stopping the hollow wheel 12, FIG. 9 illustrates the member 32 of the U-shaped frame 26 hooking the hollow wheel on the inner surface 16 of the hollow wheel 12, which is lifted by the upward motion of the handle 22 of the wheel-guiding device 10. Other methods of contact between the inner surface 16 of the hollow wheel 12 and the wheel-guiding device 10 for stopping motion of the hollow wheel 12 are possible.
In summary, the present invention is directed to a wheel-guiding device. A number of embodiments showing methods of controlling motion in various directions and stopping motion of the hollow wheel with wheel-guiding devices are described.
While the invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing and other changes in form and details may be made therein without departing from the spirit and scope of the invention.
For example, there are alternative methods by which the telescoping effect can be accomplished. The handle can be of fixed length and the wheel-guiding device would then be available in different fixed lengths. The materials of construction of the wheel-guiding device may be metals or plastics. The hollow wheel and the knob may be made of plastics or rubbers. Plastic materials may include those, which glow in the dark as a safety precaution. A small light may be attached to the wheel-guiding device as a safety precaution. Dimensions of components of the U-shaped frame may be altered to accommodate different hollow wheels. The methods of causing hollow wheels to move may differ. Hollow wheels may be replaced by solid wheels or other essentially round structures.
