BACKGROUND OF THE INVENTION
This invention relates in general to toys for pets and, more particularly, to dog toys comprising multiple, closely-connected, resilient balls.
Dog toys provide a means for enjoyment and exercise for dogs (and other pets). As is well known, balls and other pet toys that can bounce, be pounced on, grabbed, and pulled by pet's mouth are very popular. Dogs love chasing and retrieving such bouncing toys and tugging against the opposite pulling of their owners or another dog. While conventional toys of this type are enjoyed by dogs. the toys typically become worn and tattered by a dog's instinct to find weaknesses in the chew item and tear it apart.
Currently, in dog toys with balls, the balls of dog tug toys are attached to their pulling ropes with a portion of the rope exposed. The rope of some pass through holes on opposite sides of the ball and is held by a knot outside the ball, or the rope is looped through the ball and tied, or a knot is formed in the end of the rope and then inserted into the hollow center of a ball through a hole. In each of these instances the rope remains accessible to the dog, and the dog naturally chews at the rope until the rope becomes frayed and tattered.
Accordingly, there is a need for an improved dog toy that protects the toy's integrity over an extended play period, which can be bitten or chewed by a dog for many days and months without being damaged and destroyed. The present invention is a result of research, development, and experimentation concerning the above problems and ways to overcome such problems.

DESCRIPTION OF THE ILLUSTRATED EMBODIMENT
This invention, which will be described in detail below, is an improvement in dog toys of the type having a ball or other biting object for dogs to bite. The present invention overcomes the problems described above.
One aspect of this invention is a dog toy including biting objects having hollow interior cavities and a tough outer surface defining at least one opening into the cavity; and a connective member having an end portion extending into the cavity through the rope opening.
Another aspect of the invention is a dog toy including multiple resilient balls, having hollow interior cavities and tough outer surfaces defining two openings into the cavity through which the connective member may pass, and in the case of an interior ball, extend into the adjacent ball. As such, multiple balls may form a chain structure, where the tough outer surfaces of the balls protect the connective member.
The biting object may have a tennis-ball-like outer surface, and may comprise a tennis ball. Throughout this summary section and elsewhere in this specification, this invention will refer to the biting object as a “ball” or “tennis ball”, however, it is to be understood that the invention is not limited in scope by the exact nature of the biting object.
Throughout this summary section and elsewhere in this specification, this invention may be referred to as a “log,” which is used as a reference term generally for the entirety of the device, and comes from the general outward structure and appearance of several exemplary embodiments of the device.
As used herein, the term “tennis-ball-like ball” includes not only tennis balls, but any hollow ball or bouncable body that is made of a tough rubber or rubber-like material having a felt or felt-like cover. Such balls and bodies are known to be able to withstand repetitive biting by dogs without incurring significant damage. Likewise, the term “tennis-ball-like” refers to the nature of such material. In addition to its toughness, such material is both compressible and resilient; i.e., it quickly returns to its original shape when no longer in the grip of a dog's mouth. Such toys can function months or longer despite considerable abuse by dogs, especially considering that the less-durable connective member is protected by the tough outer surface of the balls.
As used herein, the term “tough outer surface” means that the material forming the ball, or other biting object, has a toughness character sufficient such that repetitive frequent biting by a typical dog, over an extended period of a month or more, will not puncture the ball or other biting object. Toughness typical of a tennis ball more than satisfies this requirement. A high-quality tennis ball, such as a Wilson® brand tennis ball, has shown to provide greater durability and toy life.
Now, referring to FIG. 1, the exemplary embodiment ball log 100 comprising ten biting objects. In the exemplary embodiment the biting objects are balls, and more specifically tennis balls. Ball log 100 comprises two end balls 110 and a series of eight interior balls 120. In the exemplary embodiment the balls are connected snugly, and may be slightly compressed from tension applied by adjacent balls.
Now, referring to FIG. 2, the exemplary embodiment ball log 200 comprising eight biting objects. In the exemplary embodiment the biting objects are balls, and more specifically tennis balls. Ball log 200 comprises two end balls 210 and a series of six interior balls 220. In the exemplary embodiment the balls are connected snugly, and may be slightly compressed from tension applied by adjacent balls.
Now, referring to FIG. 3, the exemplary embodiment ball log 300 comprising six biting objects. In the exemplary embodiment the biting objects are balls, and more specifically tennis balls. Ball log 300 comprises two end balls 310 and a series of four interior balls. In the exemplary embodiment the balls are connected snugly, and may be slightly compressed from tension applied by adjacent balls.
Referring generally to FIGS. 1-3, the exemplary embodiments show the balls uniformly oriented, such that the seams of the balls are all uniformly positioned, but this is not necessary to the function of the toy. From the provided exemplary embodiments one may see that the number of interior balls may vary without departing from the invention.
Referring now to FIG. 4, an exemplary embodiment of the device shown in FIG. 2 is shown to depict an exemplary interior construction. The end balls 210 and the interior balls 220 are shown to have a resilient outer surface 212 that forms an interior 214. In the exemplary embodiment, the interior 214 is a void, so that the ball may be described as hollow. Interior balls 220 are shown to have a pair of openings 216, which permit the passage of connective member 230. Each end ball 210 is shown to have at least one similar opening 216. Additionally, the end balls 210 may have an anchor opening 218. In the exemplary embodiment, connective member 230 is secured on each end with anchor 232, which may be a knot. An appropriate knot may actually comprise a number of simple, overhand knots, which collectively form an anchor 232 of adequate size to secure the respective end ball 210 to the adjacent interior ball 220. The length of connective member 230 is chosen to ensure a relatively snug connection between the balls, such that tension between the adjacent ball surfaces 212 inhibit access to the connective member 230. Within this disclosure, “relatively snugly” describes the amount of force between adjacent balls that effectively limits access to the connective member from between the balls, particularly during the vigorous chewing and tugging action of a large dog engaged in active play.
Referring to FIG. 5, an alternate exemplary embodiment of the device shown in FIG. 2 is shown to depict an alternate exemplary interior construction. In the exemplary embodiment, the end balls 210a are secured to the interior balls 220a by a connective member 230a comprising multiple strands. Appropriate material to construct a flexible and relatively non-stretchable connective member 230a may include 3/16th inch clothesline cord, constructed of either or both polyester and polypropylene fibers, which may be twisted or braided. To accommodate connective member 230a, anchor opening 218a may be a pair of roughly 1⁄2 inch cuts that intersect at their mid-points at or about a 90 degree angle. Exemplary connective member 230a is shown to be secured at each end by an anchor 232a, comprised of a washer 234, and a securement device 236. Exemplary securement device 236 prevents the ends of the connective member 230a from passing through washer 234 and the ball surface 212a, and out of the ball interior 214a. 
In an alternate exemplary embodiment the connective member may be a rivet, bolt, or other relatively short connector that would anchor one end within the void of one ball and the other end within the void of an adjacent ball. In this fashion multiple balls could be connected; one ball secured to the next adjacent ball, and so on. The individual short connectors could be seen collectively as a single connective member for the entire toy.
Referring now to FIGS. 6 and 7, a variety of potential designs of the current device may exist and are represented here in alternate exemplary embodiment 400. The exemplary dog log devices 400 comprise a pair of end balls 410 that may optionally be joined by one or a plurality of interior balls 420. From either end of the device the appearance is generally the same, as seen in FIG. 7. In the exemplary dog log design 400, both end balls 410 and the optional interior ball 420 have the appearance of a classic tennis ball. The anchor opening 418 may or may not be visible. The composition and nature of the particular surface of the end ball 410 may effect the degree to which the anchor opening 418 is visible.
Referring now to FIGS. 8 and 9, a variety of potential designs of the current device may exist and are represented here in alternate exemplary embodiment 500. The exemplary dog log devices 500 comprise a pair of end balls 510 that may optionally be joined by one or a plurality of interior balls 520. From either end of the device the appearance is generally the same, as seen in FIG. 9. The anchor opening 518 may or may not be visible. The composition and nature of the particular surface of the end ball 510 may affect the degree to which the anchor opening 518 is visible.
