The present invention relates generally to pet waste disposal and, more particularly, to a portable pet waste collection and disposal apparatus.
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. Such droppings are usually picked up in a bag, and then placed in the nearest trash can where they add to the waste stream, and take up space in landfills. Others, with their own yards, may choose to let Mother Nature take its course, and allow such droppings to break down on their own where they act like fertilizer. However, the feces remain an eyesore as well as a sanitation hazard for days or weeks until such breakdown happens.
Accordingly, there exists a need for a means by which dog droppings can be picked up to avoid a sanitation, and eyesore hazard, but still be used as an ecologically friendly fertilizer.
The inventor has recognized the aforementioned inherent problems and lack in the art and observed that there is a need for a waste collection apparatus that provides dog owners an effective means to clean up pet droppings during a walk in an ecologically friendly manner. The development of the present invention, which will be described in greater detail herein, substantially departs from conventional solutions to fulfill this need.

In an example implementation of use, as the apparatus 10 is propelled across the ground surface 210, the arcuate collector plate 110 lifts and transports any pet feces 220 upwardly toward the superjacent pick up roller 100 being integral to, and attached to a central portion of the front axle 102. The pick-up roller 100 includes a cylindrical member having a surface covered with bristles 101. The bristles 101 in turn convey the pet feces 220 upwardly and into the housing assembly 20 where it is subsequently fragmented and collected (see
Referring now to
In an example construction, the pick-up roller 100 includes the plurality of rigid or semi-rigid, natural or synthetic bristles 101, for example being integrally molded into or otherwise permanently affixed to a roller body 104. The front axle 102 passes through the pick-up roller 100 and extends uniformly from both ends. The pick-up roller 100 is attached to the front axle 102 by any conventional attachment device, such as tapered bushings, flanges, or threaded connections. The bristles 101 extend outwardly in a radial manner from the roller body 104 acting to contact and transfer the pet feces 220 from the collector plate 110 into the interior of the housing assembly 20.
The apparatus 10 is also configured to extract residual pet feces 220 from the bristles 101 of the pick-up roller 100 via the pick-up arm 106 that is, for example, attached to an inner surface of the top plate 22, for example by a plurality of fasteners 15.
In an example implementation, during use, the bristles 101 are acted upon by the pick-up arm 106, which is approximately the same width as the pick-up roller 100, to extract and redirect any residual pet feces 220 that may remain attached to the bristles 101.
The pet feces 220 progress through the housing assembly 20 in a travel path 230 across a plurality of progressive fragmentation rollers 130, 140, and 150 that are intended to have the cumulative effect of reducing the pet feces 220 into smaller particles. Thus, the fragmented pet feces 220 have a resultant reduced particle size and is temporarily accumulated within the rear hopper 46 of the housing assembly 20, and positioned over the hopper opening 48.
The embodiment of the apparatus 10 illustrated and described herein includes a plurality of fragmentation rollers 130, 140, 150 having a first roller shaft 132, a second roller shaft 142, and a third roller shaft 152, respectively. In this embodiment, the fragmentation rollers 130, 140, 150 are mechanically driven by the drive train 120 (

In an example construction, the sprockets 143, 146, 153 are commercially available components available in a variety of pitches as necessary for the suitable transmission of drive forces. Similarly, the drive chain 155 is a commercially available roller chain supplied in corresponding pitches and having the requisite number of links, or partial links, as necessary to encircle the sprockets 143, 146, 153. This arrangement of sprockets 143, 146, 153 and drive chain 155 preserves the desired direction of rotation as necessary to maintain the travel path 230 of the pet feces 220 through the housing assembly 20. However, in other embodiment, the transmission of the rotational motion to the fragmentation rollers 130, 140, 150 may be accomplished using various other techniques, mechanisms, and components, and as such should not be interpreted as a limiting factor.
In an example construction, the roller shafts 132, 142, 152 extend through the side panels 28a, 28b of the housing assembly 20, thereby positioning the gears 103, 133, 143, 153 within the respective first access cover 27a and second access cover 27b that are attached to the outer surfaces of the first side panel 24a and second side panel 24b of the housing assembly 20.
In an example construction, the fragmentation rollers 130, 140, 150 are arranged to slightly contact each other, thereby conveying the pet feces 220 in a rearward direction. In one (1) example, as illustrated, the fragmentation rollers 130, 140, 150 are arranged parallel to each other along a horizontal plane along the bottom panel 28 of the housing assembly 20. The first fragmentation roller 130 and second fragmentation roller 140 include similar materials and construction as the pick-up roller 100 and also include outer bristles 101. The third fragmentation roller 150 includes an outer pulverizing surface 151 including a plurality of rigid or semi-rigid, parallel rib features. The pet feces 220 is reduced into smaller particles as it is conveyed rearwardly by the fragmentation rollers 130, 140, 150.
The housing assembly 20 provides a means to service and/or clean the internal surfaces of the housing assembly 20 via a top opening 34 and a rear opening 56. The openings 34, 36 may be secured in a closed state by a top door 40 and a rear door 50, respectively. The doors 40, 50 are configured to open and close, as desired, for example, using a top door hinge 42 and a rear door hinge 52, respectively. The top door 40 is secured in a closed position utilizing a top door latch 44. The rear door 50 is secured in a closed position utilizing a rear door latch 54. The doors 40, 50 are configured to be flush with respective portions of the housing assembly 20 and made of a similar material.
