BACKGROUND OF THE INVENTION
U.S. Patent Classification Class: 119/708
The current class of pet entertainment devices mostly human-animal interactive devices. None of the current devices offer the ability to exercise and entertain animals without direct human interaction. The scope of this invention provides a method for pets to get exercise in wide open space or confined areas, which is a growing problem for many of today's pets that reside in urban environments. So, I have endeavored to create such a device to provide an outlet for the built up energy and, boredom to enhance the quality of life for our pets. One such attempt by Willinger, U.S. Pat. No. 6,217,408, describes a self-righting pet toy made of a rubber base. This device does not adjust to the dimensions of many breeds of dogs and other animals. Such a device could easily allow the animal to loose focus on the toy and return to its destructive habits due to boredom and restlessness. Another type of pet toy is a Suspended dog amusement apparatus by Lonsway, U.S. Pat. No. 6,575,119, where a device is attached to a series of walls and ceilings to provide the “suspending” of the dog when interacting with the device. The problem with this configuration is that the device is confined to the walls and structure to produce the suspension. My device is mobile and adjustable, with the ability to adapt and incorporate whatever the target animal is currently interested in and can be changed with the change of the animals interest. Therefore, I believe there is a definite need for a product that occupies our pets and provides an outlet for the excess energy pets accumulate when “cooped up” indoors or in a yard alone while the owners are away.
BRIEF SUMMARY OF THE INVENTION
It is a feature of the present invention to provide a device designed primarily to be employed in conjunction with animals such as dogs or predatory animals to stimulate exercise and play. Briefly described according to the preferred embodiment of the present invention, a toy of this invention takes the form of a rigid base with a detailed, bottom surface to incorporate the coefficient of friction properties predicted and produce an expected result in performance when the animal pulls on one of the interchangeable attachments or “top piece” of the shaft covering. When the animal pulls on the stimulant attachment, it will extend. The force created by the pull of the animal will cause the attachment and the base to sway and rotate, stimulating the animal to play and exercise. Within the hollow base of the apparatus unused toys and accessories can be added to increase the static weight of the device changing the characteristics of the toy. Some portion of the base is in contact with the surface/water to provide resistance and friction. When there is no interaction, the base will return to a centered, upright position and remain stable until external stimulus provokes movement. The primary objective of this invention is to construct an animal toy that interacts with animals and for pets, stimulates exercise and play to reduce destructive tendencies from boredom and the pitfalls of poor health.



BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS
The advantages and features of the present invention will become better understood with reference to the following more detailed description(s) and claim(s) taken in conjunction with the accompanying images, in which like elements are identified with like symbols:
FIG. 1 is a perspective view of the Description of the Preferred Embodiment of the base.
FIG. 2 is a lower view of the base to show the Description of the Preferred Embodiment of the distinct angles of the bottom of the base of the toy. (Lower view)
FIG. 3 is a profile of one embodiment of the pet toy with a “top piece” and toy attachment. (Stationary)
FIG. 4 is a view of the bottom of the base with the Description of the Preferred Embodiment of the access port to the interior of the base.
FIG. 5 is a drawing of one embodiment of the pulley system and the exit for the retraction cord.



DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION
The present invention will now be described in conjunction with the drawings beginning with;
FIG. 1, which depicts the Description of the Preferred Embodiment of the pet toy base 1. The base 1 comprising of a shape 2, on the upper section of the base 1, providing area for internal structures. The base 1 also depicts the entrance of the hollow shaft 3, where the shaft will insert within the shape 2 to the top of the external surface, depending on the size of the device due to the specifications of the target animal. This is necessary to provide rigidity for the shaft during interaction with the animal.
FIG. 2, which depicts a lower view of the Description of the Preferred Embodiment of the base 1, with the access to the interior section 4.
The angle of the outer edge 5 and the similar angle δ on the edge of the friction surface for the base 1, are essential for the proper function of the toy. The lower surface 7, is where the coefficient of friction can be adjusted due to added weight within the base. The exact weight or volume measurements can not be determined due to the personalization for each individual animal. With larger animals a larger base can be used to achieve the desired effect, and consequently for smaller animals a smaller base.
FIG. 3 is a profile of the Description of the Preferred Embodiment of the pet toy with base 1, hollow (adjustable) stem 8, “top piece” attachment 9, and a random interchangeable attachment 10. The view of the pet toy is in a state of rest. This is the position the toy will return to once interaction from an external source is removed or ceased. The attached toy is used only for demonstration purposes only and should not limit the scope of the invention.
FIG. 4 is a view of the lower surface as in a Description of the Preferred Embodiment of the base, with the access to the interior section 11, and the covering 12 of said interior section. Within the base 1 is the retraction mechanism 13, wherein the animal has a tugging stimulus for exercise or entertainment. The hollow (adjustable) stem is anchored to the upper section of the base 1 securely. The rotating mechanics of the shaft are produced by the bearing system 14 attached to the base 1 and the hollow (adjustable) stem.
FIG. 5 is a drawing of the Description of the Preferred Embodiment of the single pulley system within the hollow (adjustable) shaft of the device. The badge reel 13 located at the base of the stem, attached via the badge reel support bracket 14. The path of the retractable reel cord 15, let to the pulley wheel 16, supported by the pulley support rod 17. The retractable cord is led through the retraction limiter 18, to the hook attachment 19. Many other configurations can be used to attach the interchangeable stimulants as well as adjust the leverage and ultimate resistance of the retraction device by adding alternative reels or pulley configurations.
