BACKGROUND
The present device relates to the technical field of collecting objects, such as animal waste. Various animal waste collection devices are available on the market. Many of these devices are bulky and contaminated with odorous residue after use.
When taking an animal for a walk, users of these devices must carry the devices with them until they return home. A need exists for a device which enables the user to keep his hands free during a walk with a pet.
One pertinent reference, U.S. Pat. No. 4,747,633, discloses a disposable claw which a user can open and close around animal waste. The user discards the claw along with the waste it contains after a single use. Another pertinent reference, U.S. Pat. No. 5,540,469, discloses a waste containment device with a handle. A user may insert a bag already containing animal waste into this containment device.
The present device permits an animal owner to walk his animal and collect any waste the animal generates while keeping his hands free throughout the walk, except when the disclosed device is in use. The device disclosed herein enables a user to securely enclose animal waste within a bag, which is contained within a claw. In some embodiments, the closed claw can be attached to a holster on the user's belt without the animal waste contaminating the holster, the claw, the user or the user's apparel. Even after disposal of the animal waste and the bag containing the waste, the claw may remain clean and hygienic. Typical use of the disclosed device in conjunction with a disposable bag avoids contamination of the disclosed device with animal waste residue.

DETAILED DESCRIPTION
FIG. 1 depicts a person using one embodiment of the disclosed device to collect a piece of animal waste. Both the claw and holster, and all their components, may be produced from a variety of different materials, including plastic, metal, wood, leather, synthetic or natural fabrics, composite materials, or any combination of these materials. If the claw or holster comprises metal components, these metal components may be produced by metal fabrication techniques, including folding, welding, forging, machining, punching, shearing, stamping, cutting, or casting. If the claw or holster comprises plastic components, these components may be produced by three-dimensional printing, extrusion molding, injection molding, or other manufacturing processes. Alternatively, if the claw or holster comprises wooden components, wood glue, screws, nails, or fasteners may be used to assemble the components of the device.
FIG. 2 depicts one embodiment of the disclosed device in its first, or open, position. In this embodiment, the claw comprises two appendages 12 which open and close in a jaw-like movement, connected by a cross-bar 10 in the base region of the claw, which permits the appendages 12 to pivot. On the device depicted in the FIG. 2, both appendages 12 comprise a receptacle 14, 16 sized to accommodate a user's thumb or fingers. The cross-bar 10 provides structural rigidity to the claw and a surface to which a bag dispenser 15 and appendages 12 may be attached. Other embodiments may not require a cross-bar if the base region of the claw is composed of flexible materials which bend or give, such as leather or fabric.
Also depicted in FIG. 2 is a bag dispenser 15 attached to the cross-bar 10 in the claw's base region. The bag dispenser 15 in FIG. 2 is sized to contain a roll of disposable bags, and the bag dispenser's aperture is sized to permit dispensing of bags one at a time. The bag dispenser 15 may be created from any materials mentioned above, including synthetic or natural fabrics.
Turning now to FIG. 3, this figure depicts one embodiment of the claw in its second, closed position. In this position, the advancing member 20 and the receiving member 18 are depicted contacting each other, in their second, contacted position. Similarly, the two appendages 12 are also depicted in their second, mated position, where they touch along a shared edge. The appendages 12 may be connected to each end of the cross-bar 10 by fixing each appendage 12 to a washer and securing them to the cross-bar 10 with another washer 11.
An embodiment of the bag sealer is also depicted in FIG. 3 and includes the receiving member 18, the advancing member 20, and the actuator 19. As with the appendages 12 which touch along a shared edge when the claw is in its second position, the advancing member 20 and receiving member 18 similarly touch along a shared edge when mated in their second position. The advancing member 20 in this embodiment may be attached to an appendage 12 with a fastening piece which fits through an aperture in both the advancing member 20 and the appendage 12, and which fastens the two pieces together while still permitting the advancing member 20 to pivot about the fastening piece.
Additionally, FIG. 3 depicts a protrusion 34 fixed immovably to the surface of the advancing member 20 and an actuator 19. The actuator 19 in this embodiment may comprise an aperture and may be fastened to the advancing member 20 with the same fastening piece that secures the advancing member 20 to one appendage 12. The actuator 19 is thus able to freely pivot such that it can firmly contact the protrusion 34 and move the advancing member 20 forward in some positions. Some embodiments also may comprise a flange 36 attached to the advancing member 20 which causes the advancing member 20 to return from its second position back to its first position when the advancing member 20 is not secured to the receiving member 18. Similarly, some embodiments may comprise a retracting member 27 secured to the actuator 19 and the advancing member 20, which causes the actuator 19 to return from its second position back to its first position when the user of the device is not applying a force to the actuator 19. This retracting member 27 is attached to both the advancing member 20 and the appendage 12 to which the advancing member 20 is attached.
Returning to FIG. 2, in the embodiment depicted in that figure, the receiving member 18 comprises a groove 32, configured to receive a portion of the advancing member's edge when the advancing member 20 and receiving member 18 are in their second, contacted position, as shown in FIG. 3. Additionally, the embodiment depicted in FIG. 2 comprises magnetic portions on the receiving member 28 and magnetic portions on the advancing member 30 which cause the advancing member 20 and the receiving member 18 to releasably secure to each other when they are in the second, mated position.
FIG. 4 is a diagram of the holster 200, which is also shown in FIG. 1. In this embodiment the holster's 200 first portion 24 is configured to magnetically attach to and detach from the claw 100, and its second portion 26 is a clip configured to releasably attach the holster 200 to a user's belt. As with the claw 100, the holster 200 may comprise magnetic pieces 22 which enable it to magnetically attach to other objects. The holster 200 may comprise a protective member 25 extending a sufficient distance from the holster's 200 second portion 26 to shield the claw 100 when the claw 100 is secured to the holster 200.
- In use, the disclosed claw 100 may be detached from the holster 200, as shown in FIG. 1. The user may pull a disposable bag out from within a bag dispenser 15 fixed to the base of the claw 100. The user may invert the disposable bag around the exterior of the claw 100, as depicted in FIG. 2. If the exterior of the claw 100 has adhesive portions 29 fixed to it, these adhesive portions 29 may aid in holding the bag in place.
Returning to FIG. 1, the user may place the fingers of his operative hand into a receptacle 16 on the first appendage 12 of the claw and his thumb into the receptacle 14 on the second appendage 12 of the claw. With his operative hand inside the claw, the user may open the claw over the waste and close the claw around the waste. At this point, the waste would be secured inside the disposable bag, and a portion of the disposable bag containing the waste would be secured inside the closed claw.
In order to secure the claw in the closed position, as shown in FIG. 3, the user may push the actuator 19 forward until it contacts the protrusion 34 and forces the advancing member 20 to contact the receiving member 18. Finally the user may reattach the claw to the holster and remove his operative hand from the claw's receptacles 14, 16. At a later point, the user may again detach the claw from the holster and may use a flange 36 on the advancing member 20 to pull the advancing member 20 away from the receiving member 18, thus permitting a user to release the claw from being secured in the closed position. Finally, the user may pull the appendages 12 of the claw apart and remove the disposable bag containing the waste.
While the disclosure has been described in connection with certain embodiments, it is to be understood that the disclosure is not to be limited to the disclosed embodiments but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the scope of the appended claims, which scope is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures as is permitted under the law.
