(19) The present invention relates to a novel design for a lightweight, portable circular dog run that is adapted for quick and simple attachment to a plethora of different diameter vertical stanchions including but not limited to posts, trees, pillars, poles and the like.

(20) Looking at FIG. 1 it can be seen that the portable pet run 2 (run) when in use, is placed around a vertical stanchion 4, (illustrated herein as a tree) where the run's inner diameter is sized for frictional engagement about the outer surface of the stanchion 4 and then the distal and proximal ends of the run constrained by at least one mechanical fastener 6 passing there through. When the run 2 is formed into a circle there is a continual circular inner track 8 (FIG. 3) created that the lead anchor 10 (FIGS. 3 and 4) may freely travel in a clockwise or counterclockwise direction. The lead anchor 10 is connected to the pet's lead/leash 14 which may optionally be extendable. (FIG. 13) and since the there is a direct line at all times between the pet and the run as the pet moves about, there can be no tangling of the pet's lead/leash 14.

(21) Looking at the axial side cross section view of FIG. 2 and the top cross section of FIG. 3, it can be seen that much of the novelty of the run 2 is its simple mechanical design having only three parts: a tubular ball chase 16 (FIGS. 6, 9 and 10), a lead anchor 10 (FIG. 4), and at least one mechanical fastener 6. (FIG. 5) In the alternate embodiment there may be an additional inner sleeve 18. (FIG. 12) The inner sleeve also has a second continuous side slit formed there along, that matches the sizing of the side slit 20 formed through the outer face of tubular ball chase 16 (FIGS. 1 and 6). The outer face of said inner sleeve is frictionally engage able within the inner face of said ball chase 16.

(22) The ball chase 16 is preferably fabricated from a flexible, lightweight, durable, resilient, elastically deformable, polymer. In its native shape, with its distal and proximal ends unconnected, it is a flexible D shaped cylindrical tube. Once its proximal end 26 and its distal end 28 are connected, the ball chase has a toroidal configuration with a D shaped cross section as is best understood with reference to FIGS. 3 and 12. However, it is known that other cross-sectional profiles may be utilized such as circular, octagonal, hexagonal and the like. The reason that a D shape configuration was utilized was because this shape provides the greatest amount of contact surface area at the back face of the device to frictionally engage the tree or stanchion.

(23) The ball chase 16 has a central bore running through its entire length that forms continual circular inner track 8. (FIG. 2) It has a continuous side slit 20 formed there through its side wall, running along its front (non stanchion engaging) face, and a flat face 22 formed along its back face. There are two align able, matingly spaced series of through orifices 24 formed at the distal and proximal ends of the ball chase 16. (FIG. 3) These orifices 24 are formed in the thickest, back section of the side wall adjacent and parallel to the back, flat face 22 that defines the D shape of the ballchase 16. These orifices 24 are sized for the passage of the mechanical fasteners 6 there through. In this way when the distal end 28 is inserted into the proximal end 26 and the different spaced series of through orifices aligned, a mechanical fastener 6 can connect the ball chase 16 in a circle. (FIGS. 8 and 11)

(24) The ball chase 16 has a first, inner diameter sized proximal end 26, and a smaller, second outer diameter distal (insertable) end 28 that is sized for mating insertion into the proximal end 26. When the distal and proximal ends of the ball chase 16 are engaged (as they would be in use around a stanchion 4, as seen in FIGS. 2, 3, 7, 8, 9, 11) a toroid with a D shaped cross section is formed with a front side slit 20 and a back flat face 22. Between the distal and proximal end is first transition region 30 (FIGS. 7-9 and 11), where the outer diameter as well as the inner diameter walls of the ball chase 16 are reduced.

(25) At the first transition region 30 and continuing until the termination of the distal end, the outer diameter of the ball chase 16 is tapered to a diameter less than the inner diameter of the second transition region of the proximal end of the ball chase 16. The inner diameter of the ball chase 16 in this first transition region may reduce slightly or may remain the same as the rest of the ball chase 16. The difference results in two embodiments with different thicknesses of the side wall of the ball chase 16. Either embodiment's configuration is acceptable although in the preferred embodiment (FIG. 3) the thickness of the side wall is reduced but not until a point along the remainder of the distal length of the ball chase 16, toward the termination of the distal end 28, where there is an internal mating transitional taper 32 in the proximal end 26. (FIG. 8)

(26) The first transition region 30 occurs at the approximate middle of the length of the ball chase 16 and its reduced outer diameter extends to the distal end 28. In this way the distal end 28 of the ball chase 16 can be inserted at variable depths into the proximal end 26 of the ball chase 16 up to approximately one half of the overall length of the ball chase 16, so as to accommodate a plethora of different diameter stanchions 4.

(27) There is a second transition region 32 that occurs at the opening of the inner end of the proximal end of the ball chase 16. This second transition region has an internal taper that is compatible with the external taper of the first transition region to allow the insertion of the distal end of the ball track 16 therein. This also prevents the deformation of the thinner walled area of the ball chase from the transition region 30 to the distal end.

(28) The lead anchor 10 has a lead ring 40 with a central orifice 50 joined to a polished or smooth track sphere 42 by a linear connecting member 44. The diameter of the linear connecting member 44 is less than the width of the side slit 20. It is to be noted that the inner diameter of the ball chase 16 whether at the distal end, the proximal end or the middle of the ball chase 16 accommodates the sliding movement of the track sphere 42 of the lead anchor 10 within the ball chase 16, as the inner diameter of the ball chase 16 at all points is slightly larger than the diameter of the track sphere 42.

(29) The ball chase's exterior surface will preferably be of a matte or rough finish to enhance the frictional engagement with the stanchion 4. The inner surface will be of a smoother finish possibly with a surface treatment to decrease the sliding friction between it and the lead anchor 10. In the alternate embodiment of FIG. 12, a smooth walled, thin inner sleeve 18 with a low coefficient of friction will be inserted adjacent, applied or affixed onto the inner face of the ball chase 16. This inner sleeve 18 will be the sliding surface the track sphere 42 will run around. This inner sleeve 18 may be replaceable to accommodate wear. The mechanical fastener 6 used may be any of a plethora of common mechanical fasteners well known in the industry, including but not limited to bolts, pins, devises, rings and functionally equivalent structures. In the preferred embodiment the mechanical fastener 6 will be a threaded bolt and wing nut combination.

(30) When the track sphere 42 of the lead anchor 10 is inserted into the ball chase 16 the linear connecting member 44 extends through the side slit 20 so as to have the lead ring 42 reside about the outside of the ball chase 16. In this way the pet's lead/leash can be connected outside the ball chase 16. As the pet moves around the stanchion 4 there is friction developed between the track sphere 41 and the inner wall of the ball chase 16. To have this lead anchor 10 rotate as freely as possible around the inside of the ball chase 16 a lubricant may be added. Water or an oil are excellent choices for this lubrication.

(31) FIG. 13 is a perspective view of an optional elastic bungee or shock cord leash. This would replace the conventional lead used between the animal and the central orifice 50 of the lead ring 40. This would provide the animal a great range of travel and minimize the tangling of the leash.

(32) In the assembled configuration, the ball chase's distal end is inserted into the ball chase's proximal end at a depth that draws the flat back side of the ball chase 16 into frictional engagement with the outer surface of a stanchion 4. The pet's leash is coupled to the central orifice 50 of the lead ring 40. The pet is now free to traverse about the stanchion 4, pulling the track sphere 42 of the of the lead anchor 10 in a clockwise or counter clockwise direction around the continuous inner track of the ball chase 16.

(33) While certain features and aspects have been described with respect to exemplary embodiments, one skilled in the art will recognize that numerous modifications are possible. Similarly, while certain functionality is ascribed to certain system components, unless the context dictates otherwise, this functionality can be distributed among various other system components in accordance with the several embodiments.

(34) Moreover, system components described according to a particular structural architecture may be organized in alternative structural architectures and/or incorporated within other described devices. Hence, while various embodiments are described withor withoutcertain features for ease of description and to illustrate exemplary aspects of those embodiments, the various components and/or features described herein with respect to a particular embodiment can be substituted, added, and/or subtracted from among other described embodiments, unless the context dictates otherwise. Consequently, although only one exemplary embodiment is described above, it will be appreciated that the invention is intended to cover all modifications and equivalents within the scope of the following claims.
