## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a continuation-in-part of U.S. patent application Ser. No. 15/144,287, filed May 2, 2016, entitled “Apparatus and Method to Collect Canine Waste” which claims benefit of U.S. Provisional Patent Application No. 62/156,419 filed May 4, 2015, entitled “An Apparatus and Method to Collect Canine Waste” and which each of the aforementioned applications are incorporated herein by reference in its entirety.


BACKGROUND OF THE INVENTION
The collection and disposal of dog fecal waste is mandatory in many municipalities, aids in general sanitation, reduces insect activity, and is more sightly. The term waste will be employed as a synonym for the feces or fecal matter produced by the dogs or other living creatures.
Many dog owners or caretakers employ a device for gathering the waste off the ground and places the waste in a ubiquitous plastic bag for disposal. This system has some drawbacks; including, but not limited to, not gathering all the waste material from the ground, the possible soiling of the dog's owner during the transfer of the waste from the ground to a plastic bag, and a difficulty of those who may find it difficult to bend over to retrieve the waste.
A device which would obviate the drawbacks would be desirable.
BRIEF SUMMARY OF THE INVENTION
The invention includes a telescoping handle attached to loop. A disposable plastic bag is opened and the opened end is folded about the loop. The plastic bag is then secured to the loop on a projection located proximal to the telescoping handle. When the telescoping handle is extended, it permits a standing person to collect and dispose of the canine waste. This is performed by placing the loop and disposable bag under the anus of the dog when the dog or other animal assumes a squatting position prior to defecating. In this fashion the waste is intercepted and falls into the disposable bag as opposed to the ground. The projection holds the plastic bag in place. The upper ends of the plastic bag can be wrapped around the projection to hold the plastic bag in place. The handles of plastic bags can be placed on the projections. Then the plastic bag is easily removed from the projections so the plastic bag can be disposed of in a sanitary fashion. This can all be performed while the owner is standing. Nothing but the interior of the bag comes in contact with the waste, making the overall process more sanitary. There are no connecting devices that must be unfastened in order to secure or disengage the bag.
It is accordingly an object of the invention to provide a dog waste collection device for holding a bag, with a handle having a proximal end for a user to hold the device and a distal end opposite the proximal end, a loop affixed to the handle at the distal end, a projection extending radially away from the loop, and the projection securing the bag.
With the foregoing and other objects in view, the loop affixed to the handle is at a connection point, the projection beginning between the connection point and the proximal end.
In accordance with another feature of the invention, the projection is two projections disposed on opposite sides of the handle.
In accordance with an added feature of the invention the projections and the handle are substantially parallel to one another.
With the objects of the invention in view, there is also provided a loop with a surface roughening for assisting in gripping the bag.
In accordance with yet a further feature of the invention is a mounting block mounted on the distal end of the handle, a projection being an extension of the loop, the projection having a form lock with the mounting block for preventing a rotation of the loop relative to the handle.
In accordance with another added feature of the invention the loop has a bend that inclines a distal portion of the loop with respect to the handle.
In accordance with another feature of the invention, the telescopic handle has a proximal end for a user to hold the device and a distal end opposite the proximal end, a loop affixed to the handle at the distal end, the loop being affixed to the handle at a connection point, a projection securing the bag, the projection being disposed on the handle between the connection point and the proximal end.
The apparatus will be further explained by the drawings and their description.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to FIG. 1, a front perspective view of the dog waste collection apparatus 10 is shown, having a loop 12 which is attached to a mounting block 20. Mounting block 20 is attached to a telescoping handle 60 using a mounting block arrangement, to prevent rotation of the loop 12 relative to the telescoping handle 60.
The loop 12 is formed with an elongated tubular rod, solid or hollow, having two ends 12A and 12B. Loop 12 can have a smooth or a textured finish, the latter adding additional securing capability to maintain the bag 100 on the loop 12 when the dog waste collection apparatus is in use. As used herein, textured surface or finish means that the surface has a rough or raised texture similar to sandpaper. Referring to FIG. 3, loop 12 has a distal portion 12C, a medial portion 12D and a proximal portion 12E. The distal portion 12C and medial portion 12E of loop 12, as seen in FIG. 3, from a top view have generally a circular shape, though they can be of any shape, including oval shape or rectangular shape. The distal portion 12C of loop 12, as seen in FIGS. 2 and 8, has a bend 14 on both sides of loop 12, of approximately thirty degrees from the longitudinal axis 90 of telescoping handle 60.
In the proximal portion 12E of loop 12 the tubular rod portions of loop 12 are in the shape of two elongated parallel segments 13. Each segment 13 includes a connector pin loop opening 13A that are aligned to receive a connector pin 25 there-through.
Telescoping handle 60 has a grip 62, a telescoping arm 64 and a mounting block 20. Grip 62 is securely attached to telescoping arm 64. The distal end of telescoping arm 64 is attached to mounting block 20. Telescoping arm 64 has individual segments 64S each having a non-round profile in cross section to prevent rotation of the segments 64S with respect to one another. This prevents the loop 12 from rotating with respect to the grip 62 if a torque is applied about the axis 90.
As seen in FIGS. 10, 11 and 12, mounting block 20 is generally cylindrical in shape and has detents 21 and 22 on opposite sides of an outer wall 23 of mounting block 20. A connector pin opening 24 extends from detent 21 to detent 22 through mounting block 20 to receive connector pin 25.
Loop 12 is attached to mounting block 20 at attachment point 30 in the proximal portion 12E of loop 12. However attachment point 30 can be at any location along loop 12 where loop 12 can be attached to mounting block 20. As seen in FIGS. 3 and 10, at attachment point 30, the parallel longitudinal rod segments 13 of loop 12 are in the detents 21 and 22 and connector pin 25 is securely within connecting pin opening 24 to securely hold loop 12 to mounting block 20. The loop 12 having a form lock with the mounting block for preventing a rotation of the loop relative to the handle 60. As used herein, a form-locking connection is one that connects two elements together due to the shape of the elements themselves, as opposed to a force-locking connection, which locks the elements together by force external to the elements.
It can also be seen that a first projection 15 and a second projection 16 is located between the connection point 30 and the proximal end of telescoping handle 60. Projection 15 has an end at 12B and projection 16 has an end at 12A. A projection can be in other locations, preferably in close proximity to connection point 30. A projection can depend from loop 12, mounting block 20 or telescoping handle 60. See FIG. 10A, with projection 17 attached at 17A to mounting block 20 extending radially from mounting block 20 away from the distal portion 12C of loop 12. The projections extend radially away from loop 12.
Although connector pin 25 keeps loop 12 connected to mounting block 20, nuts and bolts may also may be used to connect different elements of the dog waste collection apparatus 10 together. Any mechanical fastener with sufficient material properties may be employed.
Referring now specifically to FIG. 2, a side view of the dog waste collection apparatus 10 is shown. The angle at bend 14 of the loop 12 is shown to be about 30 degrees. This angle may be in a range of angles from 10 to 60 degrees. The bend 14 in loop 12 facilitates the disposable bag 100 staying in place as well as permitting the bag to get underneath the dog when defecating. Additionally, it has been surprisingly found by the inventor that the bag 100 is supported more securely on loop 12, and less likely to become loosened, with the bend 14 in loop 12 than with a loop 12 without a bend 14 therein.
Referring now specifically to FIG. 7, a perspective view of the waste collection apparatus 10 with a disposable bag 100 in position around and over the loop 12, and held in place by one or more projections 15, 16. As seen in FIG. 7, if the bag 100 has bag handles 101, one or more of the bag handles 101 can be secured about a projection, including projections 15 or 16, or projection 17 in an alternate embodiment, to secure the bag 100 to the dog waste collection apparatus 10 while the dog is defecating. In the event bag 100 does not have bag handles, then the upper portion of the bag 100 can easily be twisted around one of the projections or the upper portion of the bag 100 can be pierced such that the projection will go through a portion of the upper portion of the bag 100 in order to secure the bag 100 to the projection and to the dog waste collection apparatus 10. At this point the waste collection apparatus is ready to use. When a dog needs to defecate, the user places the bag 100 under the anus of the dog (not shown). When the dog has finished, one disengages the plastic bag 100 from the projection and the loop 12. The bag 100 is then disposed in a proper manner.
In a preferred embodiment, the telescoping arm 60 from the proximal end or top of the grip 62 to the mounting block 20 is approximately 38 inches. The diameter of the loop 12 is approximately 5 to 6 inches.
FIG. 13, a front perspective view of another embodiment of the dog waste collection apparatus 10. Here, the apparatus 10 also has a loop 12 which is attached to a mounting block 120.
Mounting block 120 is attached to a telescoping handle 60 using a mounting block arrangement, to prevent rotation of the loop 12 relative to the telescoping handle 60.
FIG. 13 shows that the mounting block 120 has two tabs 121 that prevent the loop 12 from rotating and allow the loop 12 to maintain the angle α between the loop 12 and the handle 60. This view includes a handle longitudinal axis line HA along handle 60 and planar lines LP in the plane of loop 12 showing the angle α (alpha) between the handle 60 and the loop 12.
The mounting block 120 also is an element of a clamping assembly that includes a clamping magnet 122 mounted thereon. The magnet 122 serves to attract a clamping plate 123 that is pivotably mounted on the mounting block 120. Thus, the clamping plate 123 is made of a ferromagnetic material. A gripping pad 124 having an L-shaped cross-section is provided on the mounting block 120. The gripping pad 124 may be fixed onto the block by a mechanical fastener such as a screw 126 through a leg of the “L” of the gripping pad 124. The gripping pad 124 serves a counter surface that allows the clamping plate 123 to be pivoted about a pivot axis 125 thereof. Here, pivot axis is defined by pins 125 provided on an end of the L-shaped gripping pad 124. The clamping plate 123 has ears 127 with an aperture 128 formed therein. The clamping plate 123 has a finger lever portion 123a on one end of clamping plate 123 and a gripping portion 123b on the opposite end of clamping plate 123. The apertures 128 receive the pins 125 that allows the clamping plate 123 to pivot away from the magnet 122 when the clamping plate 123 and the gripping pad 124 are grasped or squeezed by a user, such as between a user's forefinger and thumb. To this end, the clamping plate 123 has a gripping portion 123b that extends beyond the pivot axis 127. This in turn allows the bag 100, which is placed around the loop 12, to be placed between the gripping portion 123b of clamping plate 123 and the magnet 122 and be clamped between planar surfaces of the clamping plate 123 and the magnet 122 as is shown in FIG. 19. Subsequently, the bag can be released, by releasing the clamping plate 123 from the magnet 122 by squeezing the clamping plate 123 at the finger lever portion 123a and the gripping pad 124 causing the gripping portion 123b to pivot away from magnet 122 and release bag 100 therebetween. Alternatively, mounting block 120 can be a magnet, thereby eliminating magnet 122.
Loop 12 is generally circular, but could be another shape. In the embodiment shown in FIG. 13, loop 12 has a pair of loop ends 15′ and 16′ that are parallel to one another. Loop ends 15′ and 16′ each have an aperture 15′′ and 16′′. Mounting block 120 fits between loop ends 15′ and 16′. Mounting block 120 has a block aperture 129 extending through mounting block 120. Loop 12 is attached to mounting block 120 with a screw 130 having a nut 131. Screw 130 extends through aperture 15′′ through block aperture 129 and through aperture 16′′ to pivotably hold parallel ends 15′ and 16′ against loop 12. This supports loop ends 15′ and 16′ against mounting block 120 and which allows loop 12 to pivot relative to handle 60 along the axis of screw 130. The rotation of loop 12 relative to handle 60, is along axis 130. As loop 12 rotates away from handle 60, the alpha angle increases to a maximum alpha angle when movement of the loop away from the handle is limited by the contact of loop ends 15′ and 16′ against tabs 121. In use, loop 12 is substantially planar as shown in FIG. 13 and said loop plane is substantially parallel to the ground, so that the opening of loop 12 is best able to catch the waste from the animal. The handle 60 is in a substantially vertical position and supports loop 12. The angle between the handle 60 and loop 12 is limited by tabs 121, forming a maximum angle of alpha. Tabs 121 support and hold loop 12 in a plane substantially parallel to the ground.
While the invention has been described in its preferred form or embodiment with some degree of particularity, it is understood that this description has been given only by way of example and that numerous changes in the details of construction, fabrication, and use, including the combination and arrangement of parts, may be made without departing from the spirit and scope of the invention.
