DETAILED DESCRIPTION OF THE INVENTION

The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of 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.

The present device for collecting and isolating waste 10 comprises three systems that work in tandem: 1) a system for ensnaring solid waste into a bag off a surface, 2) a system for closing the bag remotely, and 3) a mechanism for actuating the system for ensnaring the solid waste in the bag.

The device for collecting and isolating waste 10 and the method of using the device for picking up waste are illustrated in FIGS. 1-20. The device for collecting and isolating waste 10 is equipped with a handle 11 for holding and carrying the device. The handle 11 contains a compartment 37 for storing waste containment bags and a clip 27 for attaching a flashlight 38 to illuminate in the dark. The handle 11 may also contain a belt clip attachment 34 for belt clip 44 and optionally other accessories such as pepper spray, hand sanitizing liquid and utility pouch.

The handle may also contain a carabiner clip to hold a leash.

The handle 11 is incased by actuating system housing support cover 47 while turning collar 12 situated below actuating system housing support cover 47 is used to activate one of the waste collection steps. Signs 41A and 41B are position identifiers used for marking the position of the turning collar 12. The system for picking up the solid waste in bag 15 is contained inside waste collection housing 13.

Containment system 40 is used for collecting and isolating the waste remotely and in a way that the user does not come in contact with the waste. The containment system 40 comprises of flexible bag 15 having a drawstring 17 threaded through a channel 68 around the opening of the bag 15. The two ends of the drawstring 17 are threaded through the center of tab 67 and are attached to one another behind the tab 67 as shown in FIG. 16.

The bag 15 is stretched over the bottom opening of waste collection housing 13 and the tab 67 is seated inside tab holding slot 42 attached to waste collection housing 13 and held in a fixed position. The two ends of drawstring 17 threaded through tab 67 protrude out of the tab 67 and holding slot 42 as shown in FIG. 3. The drawstring 17 is made of elastic yet strong material. The section of the drawstring 17 that protrudes out of the tab 67 and holding slot 42 may be pulled out to tighten the elastic drawstring 17 around the bottom opening of the waste collection housing 13 to keep it securely in place.

The waste collection housing 13 comprises an inner ring 62 situated around the inner walls of the waste collection housing 13 and adapted for rotation inside waste collection housing 13. The inner bottom of waste collection housing 13 and the inner ring 62 comprise of a plurality of attachment points for attaching elastic cords 35. Each elastic cord 35 is attached at one end to an attachment point on the inner bottom of waste collection housing 13 and an attachment point on the inner ring 62 as shown in FIG. 6B. In the embodiment of FIG. 6B, six individual cords are each attached to an attachment point on waste collection housing 13 at one end and to an attachment point on the inner ring 62 at the other end. However, additional attachment points and cords also fall within the scope of this embodiment. The cord attachments shown in FIG. 6B represent a pre-use configuration 20 in which the cords are arranged in such a manner that they provide the widest open area in the center for inserting and positioning bag 15 as shown in FIG. 3.

Rotating the inner ring 62 clockwise causes the cords 35 to intertwine and reduce the center opening. The twisting of the cords 35 also creates a downward thrust on the cords 35 such that the center opening is formed at the level of the bottom housing lip before bouncing upwards due to cord flexing. This is illustrated in FIG. 6A which represents a post use configuration 30 in which the open area in the center between the elastic cords 35 is at its narrowest. With the bag 15 installed, turning the inner ring 62 clockwise results in pinching the bag at the center as illustrated in FIG. 4A. The combination of the scooping motion and center opening reduction created by the twisting of the cords 35 causes the ends of the bag 15 to be pulled off the outer side of the waste collection housing 13 on which it is stretched in the pre-use configuration as presented in FIG. 4A.

FIGS. 7 and 8 illustrate respectively pre-utilization 20 and post-utilization 30 embodiments of the waste collection and isolating device 10 for picking up solid waste 43 off a surface and isolating it in a bag 15. The device is positioned such that installed open bag 15 is centered over solid waste 43. Turning inner ring 62 clockwise causes the bag 15 to be pinched at about surface or ground level. This results in the waste 43 being snared inside the bag 15.

The system and the stepwise process for turning the inner ring 62 clockwise and actuating the system for cinching the bag 15 are depicted by FIGS. 9-14.

A cross pin 53 is wedged at each end in opposing grooves inside the turning collar 12. In a pre-use configuration 20, the turning collar 12 is adapted for movement clockwise which results in turning the cross pin 53. The cross pin 53 is engaged with a torsion spring 61 disposed over the cross pin 53 in a manner that turning the cross pin 53 clockwise applies a compression force onto the torsion spring 61 and renders it under tension. The torsion spring 61 is engaged with a clutch disk 55 disposed on a support spring 63 that applies upward pressure onto the clutch disk 55 to prevent inadvertent movement of the clutch disk 55. The support spring 63 is disposed over the torsion spring 61. The clutch disk 55 is configured for turning sideways and for upward and downward movements. The compression of the torsion spring 61 actuated by turning the cross pin causes the clutch disk 55 to turn clockwise.

The torsion spring 63 is also engaged with actuating system inner housing 52 which, in turn, is engaged with inner ring 62 in a manner that a clockwise turn of the cross pin 53 and torsion spring 61 causes an equivalent clockwise turn of actuating system inner housing 52 and inner ring 62. Conversely, a counterclockwise turn of the cross pin 53 and torsion spring 63 causes an equivalent counterclockwise turn of actuating system inner housing 52 and inner ring 62. The cross pin 53, the torsion spring 61, the clutch disk 55 and the support spring 63 for the clutch disk 55 are all supported by the actuating system inner housing 52 and are encased by the actuating system outer housing 57. The clutch disk 55 is pressed against the upper wall 58 of the stationary outer housing 57 by clutch disk support spring 63. The clutch disk 55 contains three tabs 64 that are disposed on the top surface of the clutch disk 55. It is noted that more or fewer than three tabs may be used. The upper wall 58 of the outer housing 57 contains three indentations 75 configured to house the three tabs 64 that are disposed on the top surface of the clutch disk 55 when the clutch disk 55 is turned by the cross pin 53 to compress the torsion spring 61.

The bottom part of handle 11 contains prongs 77 that are affixed to the handle 11 and whose position is over and directly opposing indentations 75 on the outer housing 57. The handle 11 is configured for downward movement which would result in insertion of the prongs 77 into the indentations 75. It is noted that the handle 11 comprising an elongated middle section is also within the scope of the current waste collection and isolation device 10 as shown in FIGS. 18A and 18B. An elongated handle middle section enables the user to avoid having to bend down in order to reach the waste.

The cross pin 53, the torsion spring 61, the clutch disk 55 and the prongs 77 on the handle 11 represent the actuation system for picking up the waste 43 and collecting it in a bag 15. As such, the clockwise rotation of the cross pin 53 compresses torsion spring 61 and rotates clutch disk 55. Pressing handle 11 causes the prongs 77 to push tabs 64 out of indentations 75 which releases the tension on the torsion spring 61 and causes the actuation system to reset to its pre-use configuration. The actuation system is engaged with bag cinching ring 62 through actuating system inner housing 52 such that turning the cross pin 53 clockwise also turns the cinching inner ring 62 clockwise.

In the inactive configuration of the waste collection and isolation device 10, torsion spring 61 is in a relaxed state and the clutch disk support ring 63 applies pressure on the clutch disk 55 to keep it pressed against the upper wall 58 of the outer housing 57. In this position, tabs 64 on the clutch disk 55 do not line up with their corresponding indentations 75 on the outer housing 57. This configuration of the mechanism for actuating the system for ensnaring the solid waste is depicted in FIGS. 12A-14D and, in the inactive position, snaring cords 35 are intertwined as shown in FIG. 6A.

To transform the waste collection and isolation device 10 to a ready to use configuration, the user would turn the collar 12 clockwise as shown in FIG. 13A. An approximate turning angle is 110 degrees; however the turning angle may be more or less than 110 degrees. Turning the collar 12 clockwise forces the cross pin 53 and the clutch disk 55 to turn clockwise an equivalent degree turn against the upward pressure exerted by the support spring 63 on the clutch disk 55. The tabs 64 on the clutch disk 55 slip into and become wedged in indentations 75 on the outer housing 57 which affixes the position of the clutch disk 55, maintains tension on the torsion spring 61 and prevents it from springing back into its relaxed configuration. Turning the collar also unwinds the snaring cords 35 into a configuration shown in FIG. 6B. The user would then install waste containment system 40 into housing 13 by first inserting tab 67 and drawstring 17 in tab holding slot 42, then spreading open the bag 15, stretching the open mouth of the bag 15 over the outer rim of the housing 13 and inserting a portion of the bag 15 wall into gripping member 85 situated at the top of external housing 13. The gripping member 85 helps maintain the containment system 40 in place. In the next step, the user places the device 10 with the open bag 15 over the solid waste 43 as shown in FIG. 7. In the inactive position, the cords 35 are twisted in such a way that the space in the center between the cords 35 is configured to be at a minimum level such that the cords 35 pinch the bag 15. In the ready to use configuration, the space between the cords 35 is configured to be at a maximum to facilitate the installation of the bag 15.

Next, the user presses onto handle 11 downward as portrayed in FIG. 14A. This causes the prongs 77 on the bottom of the handle 11 to push down on tabs 64 disposed on the clutch disk 55 causing them to dislodge from the indentations 75 in outer housing 57. This, in turn, releases the tension on torsion spring 61 causing torsion spring 61 to spring back to its relaxed position and shift the cross pin 53 back to its original first position. Likewise, the bag cinching ring 62 is rotated to twist cords 35 causing the open mouth of bag 15 to close under the solid waste 43 which is picked up and captured inside bag 15 as shown in FIG. 8. The springing back of the torsion spring takes place in a very short time which helps generate the downward thrust on the cords causing them to flex downward and twist around the bag opening at the surface or ground level and to get underneath the waste and lift it into the bag before the opening closes.

Next the user pulls on drawstring 17 which pulls the bag out of the twisted cords 35 through the narrow opening in the cords 35 toward tab 67 held in a fixed position in pocket 42 until the drawn-in opening of the bag 15 is covered with the tab 67.

The tab 67 is preferably made of a strong yet flexible and bendable plastic and as the drawn-in opening of the bag 15 is pulled onto the tab 67, the tab 67 forms a dome over the drawn-in opening of the bag 15 that prevents any unpleasant odors, germs or other hazardous gases from escaping out of the bag 15 as shown in FIG. 4C. Thus, while twisting the cords 35 around the bag opening and drawing in the bag opening with the drawstring 17 substantially closes the bag 15, the tab 67 forms an additional barrier over the mouth of the bag 15 and secures any bio-hazardous contamination that may have deposited on the inner surface of the bag 15 to be contained inside the bag 15. The preferred shape of the tab 67 is circular, however, other shapes including but not limited to square, rectangular, and multi-sided also fall within the scope of the present invention.

At this stage, the user may dispose of the containment system 40 including the bag 15, tab 67 and drawstring 17. It is noted that the user does not come in contact with the waste 43 or the bag 15; only with the drawstring from a distance removed from the bag. This setup minimizes the probability of contaminating the user or the device. The steps for closing the bag 15 and covering its drawn in opening with the tab 67 is illustrated in FIGS. 4B and 4C.

An alternate embodiment for actuating the system for ensnaring the solid waste is depicted in FIGS. 19A and 19B. Pressing trigger 78 upward causes lever arm 73 to press down onto the prongs 77 and to push tabs 64 out of indentations 75 which releases the tension on the torsion spring 61 and causes the actuation system to reset to its pre-use configuration. Another alternate embodiment for actuating the system for ensnaring the solid waste is shown depicted in FIGS. 20A and 20B. Pressing button 79 downward causes arm 71 to press down onto the prongs 77 and to push tabs 64 out of indentations 75. This releases the tension on the torsion spring 61 and causes the actuation system to reset to its pre-use configuration.

It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention.
