CLAIM OF PRIORITY 
       [0001]    The present application for patent claims priority to U.S. Provisional Application No. 61/702,503 entitled “Animal Waste Collection Device”, filed Sep. 12, 2012, which is hereby expressly incorporated by reference. 
     
    
     FIELD 
       [0002]    Various features relate to devices for collecting litter and waste and more particularly for collecting animal waste. 
       BACKGROUND 
       [0003]    There are over 78 million owned dogs in the United States. If dogs aren&#39;t taken for daily walks they tend to get bored which often leads to behavioral problems such as excessive excitement, barking and digging holes. Furthermore, the lack of activity can also lead to obesity. However, when walking dogs, it is very common for the dog to defecate, especially dogs that live in apartments who must be taken for walks to relieve themselves. 
         [0004]    It is very important for the dog walker to clean up after the dog out of courtesy and the fact that it is the law as many cities have laws requiring pet owners to clean up after their pets. These laws exist as this waste is repugnant, unsightly, smelly and a breeding medium for germs and disease. Removing the waste and disposing of it properly is therefore a public health and safety concern. 
         [0005]    Picking up the waste is not the most pleasant of tasks regardless of whether the waste is from walking a dog out in public or if the waste is located in the backyard of the dog owner. Conventional ways to clean up the waste is by the dog walker bending down and scooping up the waste into a plastic bag. However, this is very unpleasant as the individual can feel the heat from the waste and bending down increases the proximity to the waste and as a result the unpleasant smell is stronger. Additionally, individuals that have bad backs, arthritis or other health issues do not have the ability to bend down to clean up after the waste. 
         [0006]    There are a number of devices currently on the market designed to make the collection process more sanitary, including shovels and scoops, by preventing any contact directly with the waste. However, in the process of cleaning up the waste, the devices come in contact with the waste requiring the device to be cleaned. 
         [0007]    In view of the foregoing, what is needed is a device for collecting waste that allows a user to stand upright and places the waste in a disposable bag such that the non-disposable parts of the device do not come into contact with the waste. 
       SUMMARY 
       [0008]    The following presents a simplified summary of one or more implementations in order to provide a basic understanding of some implementations. This summary is not an extensive overview of all contemplated implementations, and is intended to neither identify key or critical elements of all implementations nor delineate the scope of any or all implementations.

     DETAILED DESCRIPTION 
       [0023]    The following detailed description is of the best currently contemplated modes of carrying out the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention. Furthermore, in the following description, specific details are given to provide a thorough understanding of the embodiments. However, it will be understood by one of ordinary skill in the art that the embodiments may be practiced without these specific details. 
         [0024]    While the present invention is described primarily with respect to the collection of animal waste, the present invention may be applied and adapted to collecting other types of waste, trash and yard debris such as leaves, branches and fruit that have fallen from trees or other bushes. 
         [0025]      FIG. 1  illustrates a front perspective view of a waste collection device according to one embodiment of the present invention.  FIG. 2  illustrates a side elevation view of the waste collection device of  FIG. 1 .  FIG. 3  illustrates a back perspective view of the waste collection device of  FIG. 1 .  FIG. 4  illustrates a back elevation view of the waste collection device of  FIG. 1 .  FIG. 5  illustrates a side view of a handle of the waste collection device of  FIG. 1 .  FIG. 6  illustrates a back view of a handle of the waste collection device of  FIG. 1 . The following discussion refers interchangeably to  FIGS. 1-6 . 
         [0026]    As shown, the waste collection device  100  includes a containment mechanism  102  for containing the collected waste and a scooping mechanism  104  for placing the waste in the containment mechanism  102 . In one aspect, the containment mechanism  102  may include a receptacle  106  and an elongated member  108  having a first end  108   a  and a second end  108   b , the first end of the elongated member  108  extending perpendicularly from the receptacle  106  and a handle member  110  secured to the second end  108   b  of the elongated member  108 . In one aspect, the receptacle  106  may have one or more drain holes  107  located at the bottom, backside of the receptacle  106  for allowing liquid to drain. For example, if the receptacle  106  is left outside, the drain holes  107  may prevent the buildup of water within the receptacle  106 . 
         [0027]    The handle member  110  may have a lower portion  110   a  and an upper portion  110   b  integrally connected by a side portion  110   c  forming a generally U-shaped configuration. In one aspect, the lower portion  110   a  has a first length and the upper portion  110   b  has a second length, where the second length is greater than the first length. 
         [0028]    In one aspect, a pair of opposing channels  112  may be formed in the lower portion  110   b  and side portion  110   c . The pair of opposing channels  112  may be integrally connected by a common wall portion  112   a  such that the channels are located opposite each other. The upper portion  110   b  may be used as a grip. According to one embodiment, the pair of opposing channels  112  may be used to hold multiple types of bags, such as standard plastic bags (market/garbage), by wrapping the bags around the channels  112  until ready to be used. 
         [0029]    The elongated member  108  may be releasably secured to the handle  110  by a plurality of retaining members  114  extending outwardly from the side portion  110   c . As shown in  FIGS. 5-6 , each of the retaining members  114  may have a generally curved shape for placement around the elongated member securing the scooping mechanism  104  to the handle member  110 . Each retaining member may have a first end and a second end. In one aspect, the first end of each retaining member is secured to the outer surface of the side portion  110   c  of the handle member. According to one example, the first ends of the retaining members are located in the same vertical plane on the outer surface of the side portion  110   c  of the handle member  110 . 
         [0030]    Although three retaining members  114  are shown, this is by way of example only and there may be fewer than three retaining members  114  or greater than three retaining members  114 . As shown in  FIG. 6 , the retaining members  114  may have a generally convex configuration adapted to receive the handle member  110 . The retaining members  114  enable a user to easily store and carry the scooping mechanism  104  and the containment mechanism  102 . 
         [0031]    The receptacle  106  may include a top portion  106   a , a bottom portion  106   b  integrally connected by a first side  106   c  and a second side  106   d , the second side  106   d  being a mirror image of the first side  106   c  and a back  106   e  integrally connected to the top portion  106   a , the bottom portion  106   b , the first side  106   c  and the second side  106   d . According to one embodiment, the top portion  106   a  and the bottom portion  106   b  may have a generally square or rectangular configuration and the bottom portion  106   b  may have a smaller surface area then the top portion  106   a . The first and second sides  106   c ,  106   d  may be curved having a convex shape. As shown in  FIG. 2 , the length of the top portion  106   a  (where length is defined from the opening of the receptacle  106  to the back portion  106   e  of the receptacle) may be shorter than the length of the bottom portion  106   b . As a result of the length of the top portion  106   a  being shorter than the length of the bottom portion  106   b , edges of the first  106   c  and second  106   d  sides may extend upwardly from the bottom portion  106   b  to the top portion  106   a  at a slight angle. This slight angle allows for the bottom portion  106   b  of the receptacle  106  to have a greater surface area to accept more waste and support a bag, as described below, than the top portion  106   a  of the receptacle  106 . This also provides more space for the scooping mechanism  104  inside the receptacle  106  when scooping waste into the receptacle  106 . 
         [0032]    A bag attachment member  116 , such as a ring, may extend upwardly from the top  106   a  portion of the receptacle  106 . A removable bag  118  may be placed within the receptacle  106  and wrapped around the opening of the receptacle  106  and any bag excess may be pushed and/or pulled through the bag attachment member  116  until all four (4) corners of the bag are snug around the opening of the receptacle  106  maintaining the bag in place during use. According to one embodiment, the receptacle  106  may hold three (3) pounds or more of waste while still keeping the overall size of the containment mechanism  102  minimal and easy to carry around, unlike conventional systems which typically can hold only up to 1.5 pound of waste. According to one embodiment, the receptacle  106  may accommodate a variety of sizes of bags including bathroom size trashcan bags, grocery carry bags and custom designed bags. 
         [0033]    The receptacle  106  of the containment mechanism  102  allows the user to scoop waste directly into the pre-positioned bag. After inserting the bag into the receptacle  106  prior to use, the user can scoop waste directly into the receptacle  106  lined with the pre-positioned bag. When finished, the user may tie the bag in a knot and dispose of it in the trash without getting his or her hands dirty. Lining the bag around the front of the receptacle  106  keeps it clean from waste. 
         [0034]    As described above,  FIGS. 3-4  illustrate the scooping mechanism  104  releasably secured to the handle  110 . According to one embodiment, the scooping mechanism  104  may be a rake having an elongated handle  120  with an upper grip portion  122  and a lower plate portion  124  having a plurality of tines  126 . According to one embodiment, the lower plate portion  124  may have a vertical length of 5.5 inches and a horizontal length of 5 inches. The horizontal length provides enough surface area to be efficient at picking up waste and fits conveniently into the receptacle  106  while scooping up waste. 
         [0035]    According to one embodiment the entire length of the scooping mechanism  104  may be 30.5 inches which may be shorter than conventional scoopers. Furthermore, the length of the scooping mechanism  104  may be slightly taller than the containment mechanism  102 . This length may align with the position the user is in when setting the scooping mechanism  104  in position to pick up waste. 
         [0036]    According to another embodiment, the lower plate portion  124  may have ten (10) tines  126  approximately 2 inches in length, approximately 0.5-0.75 inches in width and a gap of approximately 0.25 inches between tines. The 2 inch length of the tines offers ample flexibility when in use to easily pick up waste on different surfaces and a 0.75 inch width of each tine is wide enough to make scooping easy but thin enough to minimize the amount of residual left on the scooping mechanism  104  after scooping. Furthermore, each of the tines  126  may have a straight configuration or may have a downturned finger (or bend) for use in scratching or smoothing the soil and/or engaging debris or waste. According to one embodiment, the bend may be at an approximately 45 degree angle. 
         [0037]    The position of retaining members  114 , as described above, allow for the dirty part of lower plate portion  124  and tines  126  to face away from back of the receptacle  106  reducing contact with the dirty surface. 
         [0038]      FIGS. 5-6  illustrate plan views of the handle member  110  of the containment mechanism  102 . As described above, the handle member  110  may include lower  110   a  and upper  110   b  portions integrally connected by side portion  110   c  forming a generally U-shaped configuration. The upper portion  110   b  of the handle member  110  may extend horizontally outward from the side portion  110   c  allowing the upper portion  110   b  to be used as a grip by the user. 
         [0039]    The upper portion  110   b  of the handle member  110  of the present invention may provide for a natural position for the hand of a user to evenly carry the weight of the waste in the receptacle  106  of the containment mechanism  102 . According to one embodiment, the handle member  110  may be positioned perpendicular to the receptacle  106  for supporting the normal hand position of a person when walking, i.e. palm in and thumb facing forward. This natural hand position may create less strain on the wrist and forearm of the user when carrying the entire waste collection device  100  or just the containment mechanism  102 . Conventional scooper handles include only the stem with some type of padding for comfort. 
         [0040]    According to one embodiment, the height of the elongated member  108  of the containment mechanism  102  may be shorter than conventional containment mechanisms. The length of the elongated member  108  may be short enough for the user to be able to carry the containment mechanism  102  with his or her arm fully extended when walking and not dragging on ground. The shorter length may also provide for user comfort, for example, less strain is placed on the wrist and forearm which becomes more important as the receptacle  106  gets heavier as it is filled with waste. 
         [0041]    One or more of the components and functions illustrated in  FIGS. 1-7  may be rearranged and/or combined into a single component or embodied in several components without departing from the invention. Additional elements or components may also be added without departing from the invention. 
         [0042]    While certain exemplary embodiments have been described and shown in the accompanying drawings, it is to be understood that such embodiments are merely illustrative of and not restrictive on the broad invention, and that this invention is not be limited to the specific constructions and arrangements shown and described, since various other modifications may occur to those ordinarily skilled in the art.
