FIELD OF THE INVENTION
The present invention relates to dog waste collection and disposal devices. More specifically, the present invention relates to an inexpensive containment system for capturing dog waste when a pet owner is outdoors with their pet.
BACKGROUND
The collection and proper disposal of pet waste is a concern for today's communities. Major metropolitan cities were the first to realize the hazards of uncollected dog waste, but today it is a concern in all communities. Some municipalities have enacted ordinances to neutralize the pet waste epidemic by requiring owners to dispose of the waste or risk a large fine.
A significant motivation behind the proper collection and disposal of pet is that it carries bacteria, parasites and viruses.
Another important aspect of the pet waste issue is the corresponding environmental impact that is associated with improper disposal. Pet waste that is not sanitarily collected has a high probability of ending up in storm drains that run through our cities, some of which circumvent the local treatment facility opting to feed into local bodies of water.
DISCUSSION REGARDING PRIOR ART
The present invention addresses the prominent shortcomings relating to current pet waste collection and disposal devices. The majority of devices in the art contain similar methods for collecting the waste, which commonly requires a user to bend down below the waist, physically scoop up the waste in some form of a receptacle and then seal the receptacle thereby containing the waste. These devices don't work well for those who are unable to bend below the waist or who would rather deploy the device with only one hand. Other devices require only one-handed operation while not requiring people to bend over. The drawback to those devices is that they require a complete pickup of the waste in one scoop, and that their pickup device is contaminated with poop until clean. The present invention has a plastic plate on the metal plate which is removed automatically, and a compartment that closes the disposable plastic container and the paper bag.
Listed below are some of the more prominent inventions in this field and a description of how they differ from the present invention.
One-handed devices similar to the present invention.
U.S. Pat. No. 3,986,744 (David Krogstad, George A. Nigro) maybe the closest patent to the present invention. It has an open-ended, tubular, scoop-like body and has a flat bottom wall which constitutes a scoop proper and the forward edge of which is provided with comb-like teeth. The plate rotates upwards into a cavity on the device to dispose of the waste. The present invention does not rotate upward, but rather rotates horizontal to the ground depositing the waste into a paper bag that is attached to a plastic plate.
U.S. Pat. No. 5,503,442 (Ke-Cheng Lee) A device for picking up animal feces, comprising a stick member, a D-shape handle mounted on said stick member at one end, a scoop assembly mounted on said stick member at an opposite end, and a control mechanism mounted on said D-shape handle and controlled to open/close said assembly. Again this device plate rotates upward.
U.S. Pat. No. 8,002,319 (Joseph Hahn) this patent is also somewhat close to the present invention. A pick-up device for picking up animal feces, including a stick member, a D-shaped handle mounted on the stick member at one end, a scoop assembly mounted on the stick member at an opposite end, and a control mechanism mounted on the D-shaped handle and controlled to open/close the scoop assembly. The scoop assembly in this device rotates upward, rather than rotating horizontal to the surface.
U.S. Pat. No. 8,627,974 (Carl Ajax Francis) claims a system for the sanitary collection and disposal of pet waste. The system comprises adjacent male and female receptacles connected by a pull string. The male receptacle contains an open bottom for the purpose of being deployed over targeted waste, while the female receptacle contains an opening most adjacent to the male receptacle in order to allow for their joining. The user secures the female receptacle and applies a tension to the pull string, allowing the smaller dimensioned male envelope to be pulled into the female receptacle interior. This device again rotates the bottom plate up.
US20090278365 (Arlen Hawks) has a pickup container but does not have a pick up plate, rather the container slides under the waste for pickup.
Devices requiring two hands rather than the one-handed operation of the present invention.
U.S. Pat. No. 4,272,116 (Ralph W Tufte, Jr) details a collapsible generally rectangular container having an open forward end and an integral handle by which an operator may support and manipulate the container. It also includes a spatula to help place the waste in the container and to enclose the waste.
U.S. Pat. No. 4,972,116 (Paul E. Grahn) includes a container which is slid under the deposit to transfer the waste material to the container. It has a separate device which to push the waste into the container.
U.S. Pat. No. 5,186,384 (Robert J. Nelson) details a receptacle that includes a collapsible container having a selectively sealable opening for enabling access to the interior of the container and an integrated handle for carrying the container. The handle has a detachable scoop stick for gathering up animal waste and placing the wastes in the container through the opening.
U.S. Pat. No. 6,471,267 (Katsuya Katz Asazuma) details a collapsible frame for positioning a flexible membrane to capture and collect animal waste. From a folded, retracted condition capable of being stored in a pocket or easily carried, the present invention springs open using hinges that open to form a polygon frame with an open interior.
U.S. Pat. No. 6,648,387 (Michael Kaplan) claims a canine waste collection device comprising a handle and a frame member, connected to one end of the handle, wherein the frame member comprises a slotted member for receiving and securing of a disposable paper element.
U.S. Pat. No. 6,964,247 (Haun-Chin Lin) claims an excrement container that includes a hollow box body having an opening. The box body and the cover body are connected to a hanging body. A first inner cup and a second inner cup are contained in the box body. The second inner cup is inserted and disposed into the first inner cup. Each inner cup is in a box shape, which can be flattened into a thin flat sheet.
None of the prior art patents discovered include the prominent feature of the present invention which is a scooping plate that rotates parallel to the ground surface.
The difference between this patent invented by Tobias Luk, and patent #10392760, Pet Refuse Collecting Device with Scooping Plate, also invented by Tobias Luk, issued Aug. 27, 2019 are:
- 1. a round knob that pulled out to hold the flat bar in place are not present;
- 2. the two holes in the main flat plate that the round knob fits into are not present;
- 3. The bottle, bottle holder, and dispensing rod for dispensing cleaning fluid, germicide or other are not present;
- 4. The accessory compartment is not present;
- 5. The long hook for closing the bottom of the device is not present;
- 6. The ejector and its rod outside the main tube is no longer present.
SUMMARY OF THE INVENTION
The present invention is a containment system device for capturing dog waste utilizing a disposable plastic plate with a paper bag (specially constructed for use in this device) connected to it, and a moveable steel plate. When in operation, the scooping mechanism is turned at a 90-degree angle to the vertical portion of the device, and the steel plate pushes the waste into the paper bag. The operation of the device controlled by two mechanical mechanisms, one a “U” shaped device near the top of the handle that can be pulled down allowing an internal flat plate to be raised which in turn allows the steel plate, plastic plate, and paper bag to turn at a 90-degree angle when in use, and a two-part lever near the top part of the main structural tube, with the top part of the two-part lever stationary, and with a bottom part can be pulled up towards the handle, which when the lever is pulled toward the handle closes the hinges which then closes the steel plate into the specially constructed paper bag depositing the waste into the paper bag. The steel plate, the plastic plate, and the paper bag are attached to the vertical section of the device at a 90-degree angle to the tubular vertical portion of the device when in use and are at a 180 degree angle to the vertical portion of the device when not in use. After pet refuse is collected the device can be shook to remove the bag from the device.
Main components of the Pet Refuse Collecting Device with Scooping Plate are comprised of the following items.
- 1. A vertical main tubular bar which is the center of the device.
- 2. A scooping mechanism attached to the bottom of the tubular bar that can rotate from a 90-degree angle to the tubular bar to a 180-degree angle to the tubular bar.
- 3. A main flat bar within the tubular that is the conduit for action related to the rotation of scooping mechanism 90 degrees, the main flat bar resting inside the vertical support tube is connected to a short flat bar attached to a vertical support plate within the scooping mechanism.
- 4. A singular cable that runs from the end of the “U” shaped mechanism that is attached to the end of the handle with the singular cable being held in place to the main part of the flat bar with a friction fit When the “U” shaped device rotates 90-degrees from the handle, and the pull-out locking know is in the pulled-out position, the main flat bar is raised. The singular cable attaches through the scooping mechanism housing to a flat plate attached to the vertical support plate. The singular cable moves through the housing, at the location where the flat plate attached to the vertical support plate rest when rotated 90-degrees. Moving the flat plate attached to the vertical support plate will move the scooping device from the 180-degree position (downward position) to the 90-degrees position by rotating the flat bar attached to the vertical support plate 90-degrees.
- 5. A two-part lever near the top of the tubular device, with a stationary top part and a movable bottom part, which when the lever is pulled toward the handle pulls the main cable attached through a connector to two secondary cables that are attached to the ends of the two clamping devices, one on either end of the scooping mechanism causing the clamping devices to move creating the scooping and collection action of the device to occur.
- 6. A scooping collection mechanism on the bottom of the tubular bar consisting of a steels plate on the right-hand side (looking from the front of the device) of the device and a plastic frame on the left-hand side of the device which holds a disposable plastic plate and a specially constructed paper bag for collection. The middle of the scooping mechanism has a vertical support plate that attaches to the sections of the steel support plate and the plastic plate that are in the middle of the scooping mechanism,
- 7. A clamping mechanism system that moves the steel plate towards and away from the collecting paper bag, the clamp operated by the movement main cable which is moved up and down by the two-part lever near the top of the tubular bar. That main cable attaches through a connector to two cables that go down the vertical support plate and run along the edge of the flat scooping plate and plastic plate to the two ends for the clamping mechanism.
- 8. A detachable tray which sits below the scooping and collection components when the device is not in use to prevent refuse from escaping.
- 9. The vertical support plate within the scooping mechanism that supports both the steel scraping plate and the plastic support frame.
Other potential embodiments of Pet Refuse Collecting Device with Hand Operated Scooping Plate include:
- 1. for the scooping collection mechanism may have varying lengths and shapes
- 2. the shape and length of the non-tubular bar may vary;
- 3. the short connecting bar within the tubular device which turns the scooping collection mechanism to the 90-degree moves can be replaces by a tubular rectangular bar;
- 4. the vertical tubular bar that is the main support part of the invention could be a square, oval, or rectangular bar;
- 5. the singular cable starting in the “U” shaped mechanism in in the handle, which allows the device to operate at a 90 degree position when the locking mechanism is turned 90 degrees down from the handle could be a two-part cable, one the cable going from the “U” shaped device to the top of the main flat bar, and the other going from the bottom of the main flat cable through the housing to the bar attached to the vertical support plate;
- 6. the scooping and collecting mechanism could rotate to angle from 45 to 90 degrees, rather than just 90 degrees;
- 7. The two-part lever could be a round handle or other shape versus a horizontal bar.
- 8. The non-tubular bar that closed the collection device could a flat piece, or a tubular bar, or other shape.
- 9. The detachable tray may be eliminated;
Advantages of the Invention
- 1. Enables one-handed operation of a pet refuse scooper.
- 2. Offers an effective method off picking up pet waste with the 90-degree scooper position into a collection bag.
- 3. Provides an effective method of waste disposal, disposing of the plastic bac and plastic scraper.
- 4. The device is easy to operate while the pet leash is held in the other hand.

DETAILED DESCRIPTION OF THE DRAWINGS
FIG. 1 shows the basic configuration of the Pet Refuse Collecting Device with Scooping Plate, The device has a handle 1 on top. With a “U” shaped mechanism 2 (See FIG. 4 for more detail) that moves the flat bar mechanism, 10 and 18 that allows the device to move from a 180-degree to a 90-degree configuration. The flat bar movement is allowed by the pull-out locking knob 9 and two holes 8 in the flat bar 10 which al lows the bar to be locked into either the 90-degree or 180-degree configuration. The flat bar 10 has a hole in top 3 which is connected to a cable 28, shown in FIG. 4 and FIG. 5 which moves the flat bar up and down depending on the position of the “U” shaped mechanism 2. There is also a removable tray 23 on the bottom that may be placed underneath the scooping mechanism when it is no longer in use.
The scooping mechanism itself consists of the clamping mechanisms 14 on either side of the scooping mechanism, see FIG. 3 for more detail, a steel scooping plate 15, which scoops the waste material into a paper bag 17, which is held in place by a disposable plastic frame 16. FIG. 1 also shows the two eyelets, 13, which allow the cable 28 (see FIGS. 4 and 5) from the handle 1 through the top hole in the flat bar 3 to manipulate the flat bar 18 attached to the scooping mechanism, which has the cable 28 attached to the end of the flat bar 18.
FIG. 2 illustrates the scooping mechanism when it is turned at a 90-degree angle. The clamping mechanism 14 is on the top and bottom of the scooping mechanism. The steel plate 15 is on the left side (looking towards the drawing), and plastic frame 16 for the paper bag 17 is on the right side looking toward the picture.
FIG. 3 shows the clamping mechanism from one side of the device. The main cable 19 from the two-part lever 21 goes into a connector 26, which then has two cables, 27 one to the clamping mechanism 14 on either side of the scooping mechanism. When the cable 19 is pulled up by use of the two-part lever, the two clamping mechanisms closes causing the scooping action.
FIG. 4 shows the handle 1 with the “U” shaped mechanism 2. The locking mechanism 2, is attached to the cable 28. When the “U” shaped mechanism 2 is pulled down, it pulls the cable 28 which raises the main flat bar 10, as the cable 28 is wrapped through the flat bar 10, which in turn raises the flat bar 18 attached to the scooping mechanism housing turning the scooping mechanism 90-degrees. In order for all the above to happen the pull-out locking knob 9, must be pulled out and then reinserted once the flat bar 18 has reached its 90-degree hole.
