## Background
RELATED APPLICATIONS
The present invention was first described in and claims the benefit of U.S. Provisional Application No. 61/929,729, filed Jan. 21, 2014, the entire disclosures of which are incorporated herein by reference.


FIELD OF THE INVENTION
The present invention relates generally to a pet waste catcher device with a ring member to retain disposable bags located at the end of a shaft, wherein the ring is manipulated by a user.
BACKGROUND OF THE INVENTION
The act of walking a dog or other pet is a pleasure enjoyed by many pet owners. The ability to get outside and experience nature and the surroundings is a simple joy. There are also the great health benefits associated with exercise for both the dog and the human walker. However, one (1) additional task associated with walking of a dog is the cleaning up of droppings. This act is not only the responsible thing to do, but it is the sanitary thing to do as well. To accomplish this task, one must carry a bag and a small shovel with them as the dog or pet is being walked or come back later without the pet to retrieve the droppings. In either case it is a messy, smelly situation that no one enjoys. It also requires bending over to perform the task, which many such as the elderly or disabled are incapable of doing. Accordingly, there is a need for a means by which one can quickly and effectively retrieve dog or pet droppings without the mess, fuss and the requirement to bend over.
SUMMARY OF THE INVENTION
The disadvantages of the prior art are overcome by the present invention in providing a pet waste catcher device having an extendable handle comprising a first handle segment, a second handle segment disposed within and extendable from the first handle segment, and a third handle segment disposed within and extendable from the second handle segment. The catcher has a ring assembly disposed at an end of the extendable handle that retains and holds open a disposable bag. A case for the user is also disposed on the handle of the catcher. The use of the present invention provides dog owners an effective means to clean up pet droppings during a walk in a manner which not only does not require them to bend over, but is quick, easy and effective as well.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The best mode for carrying out the invention is presented in terms of its preferred embodiment, herein depicted within FIGS. 1 through 8. However, the invention is not limited to the described embodiment, and a person skilled in the art will appreciate that many other embodiments of the invention are possible without deviating from the basic concept of the invention and that any such work around will also fall under scope of this invention. It is envisioned that other styles and configurations of the present invention can be easily incorporated into the teachings of the present invention, and only one particular configuration shall be shown and described for purposes of clarity and disclosure and not by way of limitation of scope.
The terms “a” and “an” herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced items.
The present invention describes a pet waste catcher (herein referred to as the “apparatus”) 10, which provides a sanitary disposal means for collecting the excrement of a pet in a disposable bag 100 retained in a ring assembly 50 located at a distal end of an extendable handle assembly 20. A hinged case assembly 70 is provided at a proximal end of the extendable handle 20 for the temporary storage of items selectively chosen by a user. It should be noted that the size of the pets to which this apparatus 10 can be used may vary considerably, it is intended that the preferred embodiment of the apparatus 10 be produced in a range of sizes without limiting the scope of the invention.
Referring now to FIG. 1, an isometric view of the apparatus 10 according to the preferred embodiment of the present invention, is disclosed. The apparatus includes an extendable handle assembly 20, a ring assembly 50, and a hinged storage case assembly 70. The extendable handle assembly 20 is configured with a first handle segment 22, a second handle segment 30, and a third handle segment 40. The handle segments 22, 30, and 40 are preferably fabricated from PVC pipe of a size and schedule to achieve a sliding fit with each other. The first segment 22 fitting within the second 30, and the second 30 fitting within the third 40. As shown in FIG. 8, disposed on the distal end of the second handle segment 30 is a second segment external taper 34 and a second segment external threading 36. The second segment external taper 34 is the result of the removal of a decreasing amount of the tube wall of approximately one inch (1 in.) of the distal end of the second handle segment 30. The distal end of the second handle segment 30 preferably has four (4) second segment kerf 32 slots in the second segment external taper 34 which are accomplished with two (2) perpendicular saw cuts across the diameter of the second handle segment 30.
The second segment external threading 36 receives and retains a first collet ring 23. The first collet ring 23 is an annular ring, preferably constructed of a thermoplastic material, formed with a first ring internal taper 25 and a first ring internal threading 24 as seen in FIG. 7. The first ring internal taper 25 would preferably be the complementary form of the second segment external taper 34 disposed upon the second handle segment 30, while the first ring internal threading 24 would be a mating thread to the second segment external threading 36. It is understood that other materials may be used in the fabrication of the first collet ring 23 without limiting the scope of the apparatus 10.
According to the preferred embodiment, the first collet ring 23 is installed on the second handle segment 30 by engaging the first ring internal threads 24 with the second segment external threading 36. Then, the proximate end of the first handle segment 22 is inserted into the distal end of the second handle segment 30, through the first collet ring 23 to a desired depth. The further engagement of the mating threads, preferably beyond three (3) turns results in the first ring internal taper 25 coming in contact with the second segment external taper 34 on the second handle segment 30. The further threading of the first collet ring 23 results in the deformation of the distal end of the second handle segment 30 at the taper 34 and causes a consequential narrowing of the second segment kerfs 32 to engage the outer wall of the first handle segment 22 and limiting the telescoping action between the first handle segment 22 and the second handle segment 30.
Similarly, disposed on the distal end of the third handle segment 40 is a third segment external taper 44 and a third segment external threading 46. The third segment external taper 44 is the result of the removal of a decreasing amount of the tube wall of approximately one inch (1 in.) of the distal end of the third handle segment 40. The distal end of the third handle segment 40 preferably has four (4) third segment kerf 42 slots in the third segment external taper 44 which are accomplished with two (2) perpendicular saw cuts across the diameter of the third handle segment 40.
The third segment external threading 46 receives and retains a second collet ring 27. The second collet ring 27 is an annular ring, preferably constructed of a thermoplastic material, formed with a second ring internal taper 29 and a second ring internal threading 28 as seen in FIG. 7. The second ring internal taper 29 would preferably be the complementary form of the third segment external taper 44 disposed upon the third handle segment 40, while the second ring internal threading 28 would be a mating thread to the third segment external threading 46. It is understood that other materials may be used in the fabrication of the second collet ring 27 without limiting the scope of the apparatus 10.
According to the preferred embodiment, the second collet ring 27 is installed on the third handle segment 40 by engaging the second ring internal threading 28 with the third segment external threading 46. Then, the proximate end of the second handle segment 30 is inserted into the distal end of the third handle segment 40, through the second collet ring 27 to a desired depth. The further engagement of the mating threads preferably beyond three (3) turns would result in the second ring internal taper 29 coming in contact with the third segment external taper 44 on the third handle segment 40. The further threading of the second collet ring 27 results in the deformation of the distal end of the third handle segment 40 and causes a consequential narrowing of the third segment kerfs 42 to engage the wall of the second handle segment 30 and limiting the telescoping action between the second handle segment 30 and the third handle segment 40.
Referring now to FIG. 2, an isometric view of the apparatus 10, depicted in a collapsed or stowed configuration, according to the preferred embodiment of the present invention is disclosed. The first collet ring 23 can be loosened to allow the first handle segment 22 to telescope into the mating second handle segment 30. The first collet ring 23 can then be tightened, in the aforementioned manner, to retain the first handle segment 22 relative to the second handle segment 30. In a similar fashion the second collet ring 27 can be loosened to allow the second handle segment 30 to telescope into the mating third handle segment 40. The second collet ring 27 can then be tightened to secure the second handle segment 30 relative to the third handle segment 40. The first collet ring 23 and the second collet ring 27 are preferably configured to have a knurling 26 around the exterior surface to improve a user's grip for turning.
Referring now to FIG. 3, a detail view of the ring assembly 50 of the apparatus 10, according to the preferred embodiment of the present invention, is disclosed. The ring assembly 50 includes a first ring 52 and a second ring 62 which are each preferably composed of a thermoplastic material and formed in an injection molding process. Other materials and other methods of fabrication may be utilized without limiting the scope of the apparatus 10. The first ring 52 is configured to have a portion of the first inner ring wall 53 extended to incorporate a first ring apron 54 for the purpose of attaching an elbow 68. The elbow 68 is configured as two (2) thermoplastic cylinders of unequal length with the longitudinal axes of the cylinders disposed at approximately one hundred sixty five degrees) (165° to each other. The first ring 52 may be formed as one (1) piece with the elbow 68 or may alternately be attached to the shorter cylinder of the elbow 68 with an adhesive. The diameter of the longer cylinder of the elbow 68 is preferably slightly larger than the inside diameter of the first handle segment 22 such that a press fit is required for assembly. The inside diameter of the first ring 52 is preferably configured to be uniformly decreasing from the lower edge to the upper edge so as to form a first ring taper 56.
The second ring 62 fits within the first ring 52 by a taper fit wherein the outside diameter of the second ring 62 is preferably configured to be uniformly decreasing from the lower edge to the upper edge to form a second ring taper 64 that matches the profile of the first ring taper 56. The second ring 62 also includes a bag lip 66 disposed about its upper edge to obviate any sharp corners which may damage a collection bag 100. In this manner a top of a disposable plastic bag 100 is brought up through the second ring 62 and folded back over the bag lip 66, then the second ring 62 and bag 100 are inserted into the bottom of the first ring 52, the matching first ring taper 56 and the second ring taper 64 cooperate to clamp the bag 100 between the two rings 52 and 62.
Referring now to FIGS. 4 and 5, detail views of the case assembly 70, and FIG. 6, a section view along line B-B as seen in FIG. 2, of the apparatus 10, according to the preferred embodiment of the present invention, are disclosed.
