(34) FIGS. 1-4 illustrate a first embodiment of the present invention, which may include a ball throwing device 100 and an accessory 200 that may be releasably mounted to the ball throwing device.

(35) FIGS. 5-12 illustrate various views of the ball throwing device 100. The ball throwing device 100 may include an elongated arm portion 103. A first end of the elongated arm 103 may transition into, or have fixedly secured thereto, a ball holder 104. The ball holder 104 may have an interior surface 104I that may be formed to generally match a portion of the spherical shape of the ball. The ball holder 104 may also be formed with a plurality of fingers having tips 104T that may protrude inward slightly (i.e., into the theoretical sphere envelope) so that the ball holder may just be able to retain the ball therein even when inverted with the ball facing towards the ground. Other shapes for releasably supporting the ball that are known in the art may alternatively be used (see e.g., the protrusions of the ball holder accessory 200 shown in FIG. 13). A second end of the elongated arm 103 may transition into a handle portion 105. The elongated arm 103 and the handle portion 105 may be integrally formed as a unitary piece, or may alternatively be formed as separate parts that may be fixedly secured together. It should be noted that the all three portionsthe elongated arm portion 103, the ball holder 104, and the handle portion 105may be integrally formed as a unitary piece.

(36) In one embodiment the elongated arm portion 103, the ball holder 104, and the handle portion 105 of the ball throwing device 100 may be made of plastic. In other embodiments, other suitable materials may alternatively be used. Also, the handle may be over-molded with rubber or another suitable material to provide for better gripping of the device by the user's hand.

(37) To accommodate attachment of various different interchangeable accessories, the ball throwing device 100 may be formed with a mounting member 120. The mounting member 120 may be positioned on the elongate arm 103, and in one embodiment may be positioned on the arm in proximity to the handle 105. As seen at least in FIGS. 10-12 and in FIG. 19, the mounting member 120 may include a first flange 121 and a second flange 122. The first flange 121 may be formed to protrude away from the elongate arm 103 to a distal end, and the second flange 122 may be formed to protrude away from at least a portion of the first flange, in proximity to the distal end. The second flange 122 may be used to create a key that may prevent the accessories (e.g., accessory 200) from sliding off of the first flange in a direction being generally perpendicular to the axial direction 100A (see FIG. 9) of the elongated arm 103. In one embodiment the second flange 122 may be formed to protrude away from the first flange 121 at an acute angle. In another embodiment the second flange 122 may be formed to protrude substantially perpendicularly away from the first flange 121 to form a T-shaped key, as seen in FIG. 19.

(38) Each of the interchangeable accessories, including accessory 200, which is shown in detail in FIGS. 13-17, may be formed to include a mounting flange 220 that may have an opening (i.e., a keywaysee FIGS. 15-16) that is configured to slidably receive the mounting member 120 therein, to releasably couple the accessory to the ball throwing device 100. The keyway of the mounting flange 220 may be formed to correspond to the particular key shape that is used. Where the T-shaped key is used for the mounting member 120 on the ball throwing device 100, the keyway of the mounting flange 220 of the accessory will having a corresponding T shape.

(39) In one embodiment the surfaces 221i and 221ii of the keyway of the mounting flange 220 may be formed to be substantially flat and parallel, and may be spaced apart to be received upon the thickness of the first flange 121 using a clearance fit. As shown by the gaps G1, G2, and G3 in the enlarged view of FIG. 20, the second flange 122 of the ball throwing device 100 may be received in the corresponding portion of the keyway of the mounting flange 220 in a clearance fit throughout its extent, and may thus permit a very small amount of sliding laterally (e.g., perpendicular to the axial direction 100A of the arm 105).

(40) In another embodiment, the surfaces 221i and 221ii of the keyway of the mounting flange 220 may be formed to be substantially flat and parallel, but may be spaced apart to be received upon the thickness of the first flange 121 using a friction fit. The friction fit (i.e., an interface fit) therebetween may be a slight interference in one embodiment and may be in the range of 0.0001 inches to 0.0003 inches, or an interference of 0.0003 inches to 0.0007 inches in another embodiment, or an interference of 0.0007 inches to 0.0010 inches in yet another embodiment, or a combination of such ranges. Other sizes to provide the interference fit may also be used in different embodiments (see e.g., Press Fit Engineering and Design Calculator, available at: www.engineersedge.com/calculators/machine-design/press-fit/press-fit-calculator.htm).

(41) This interference fit may help to generally deter dislodgment (sliding) of the accessory off of the mounting member 120 in the opposite direction that it was mounted, when the ball throwing device 100 is used for throwing the ball. Note that a flange/stop 122E shown in FIG. 9 may prevent sliding of the accessory off of the mounting member 120 in the same direction that it was mounted. To assist in initially coupling the mounting flange 220 of the accessory to the mounting member 120 of the ball throwing device 100, a chamfer 221C may be formed on the ends of each of the surfaces 221i and 221ii, as shown in FIG. 17.

(42) To better prevent such accidental sliding and inadvertent decoupling of the accessory from the ball throwing device 100, the first flange 121 may additionally/alternatively be formed with at least one recess (e.g., recess R1i), and at least one of the surfaces 221i and 221ii may be formed with a protrusion that may be sized to engage and contact a portion of the recess. In another embodiment, the first flange 121 may be formed with at least one recess on each side of the flange (e.g., recess R1i and recess R1ii), and each of the surfaces 221i and 221ii may be formed with a corresponding protrusion (e.g.. 221Pi and 221Piisee FIG. 17), which protrusions may be sized to engage with, and may contact a respective portion of the recesses. In another embodiment, a plurality of pairs of recess may be used (e.g., R1i and R1ii; R2i and R2ii; R3i and R3ii; R4i and R4ii; R5i and R5ii; etc.), where each of the pairs of recesses may be respectively (and successively) engaged by the protrusions 221Pi and 221Pii.

(43) The protrusions may each be formed to any suitable shape, and in one embodiment they may be cylindrical having a radius R.sub.P. Alternatively, they may have an elliptical shape, or another curved shape, or may even have a rectangular shape. The recesses may also be formed to any suitable shape that may correspond to the shape used for the protrusion(s), and in one embodiment, the recesses may be formed to be cylindrical, and may furthermore be formed to have the same radius as the radius R.sub.P of the protrusions. In another embodiment, to better facilitate removal, the recesses that may be formed to be cylindrical may be formed with a larger radius than that which is used for the protrusions. Also, in one embodiment, as seen in FIGS. 10-11, the recesses may be spaced a small distance apart from each other, which may require more deliberate/continuous action on the part of the user to effect separating of the two parts, and which may better serve to prevent dislodgment during vigorous use of the device by a user. In another embodiment, the recesses may not be spaced apart, and the flat therebetween may furthermore be replaced with a concave surface (e.g., the succession of recesses may form a sinusoidal shape).

(44) The length L1 of the mounting member 120 of the ball throwing device 100 (FIG. 9) may be formed to accommodate the mounting flange 220 of the accessory 200 in any one of several different ways. In one embodiment (e.g., where there may only be one pair of recesses, R1i and R1ii), the length L1 of the mounting member 120 may be just sufficiently long enough to receive the entire length L2 of the mounting flange 220 of the accessory 200 (FIG. 14) so that the protrusions 221Pi/221Pii engage the recesses R1i/R1ii, which may be at either end of the mounting flange. In another embodiment, where a plurality of pairs of recesses are used, the length L1 of the mounting member 120 may be longer than the length L2 of the mounting flange 220 of the accessory 200, so that the protrusions 221Pi/221Pii may nonetheless be able to engage the last of the pair of recesses on the flange, as shown in FIG. 2, and the entire length L2 of the mounting flange 220 may be mated with the entire length L1 of the mounting member 120, no matter which set of recesses are engaged by the pair of protrusions 221Pi/221Pii.

(45) As seen in FIGS. 21 and 22, an accessory 300 having the same mounting features as accessory 200 may instead be configured as a container that may hold and may individually dispense pet waste bags 399. The accessory 300 may have a container portion 301 and a removable cover 302, which may have a plurality of radial slits, through which the pet waste bags 399 may be pulled out, one at a time.

(46) As seen in FIGS. 23 and 24, an accessory 400 having the same mounting features as accessory 200 may instead be configured as a container that may hold pet treats. The accessory 400 may have a door 401 that may be pivotally mounted to the container portion 402 using a hinge 403. A handle 404 may be used to open/close the door 401, which may be maintained in a closed position using a latch. The latch may include a member 405 (e.g., a hook member) that may be retained in the closed position using a detent arrangement housed within the container portion 402, similar to that disclosed by U.S. Pat. No. 6,447,030 to Meinke. Other latch arrangements may also be used.

(47) While illustrative implementations of one or more embodiments of the present invention are provided hereinabove, those skilled in the art and having the benefit of the present disclosure will appreciate that further embodiments may be implemented with various changes within the scope of the present invention. Other modifications, substitutions, omissions and changes may be made in the design size, materials used or proportions, operating conditions, assembly sequence, or arrangement or positioning of elements and members of the exemplary embodiments without departing from the spirit of this invention.

(48) Accordingly, the breadth and scope of the present disclosure should not be limited by any of the above-described example embodiments, but should be defined only in accordance with the following claims and their equivalents.
