Waste disposal device including an external actuation mechanism to operate a cartridge
View Patent ↗A waste disposal device comprises a container having a lid. An externally accessible actuation mechanism comprising a rack and a pinion is connected to the lid, and is operatively configured to interface with a foot pedal. When the actuation mechanism is actuated by pressing the foot pedal, the lid opens, while the rack skips over the pinion. When the foot pedal is released, the rack engages the pinion, which in turn closes the lid and spins a cartridge of the device one revolution.
1. A waste disposal device, comprising:
a container defined by a circumferential wall having an outer surface;
an actuation mechanism capable of moving from a first position to a second position, and being accessible through said outer surface of said container;
a cartridge having a pinion that operatively interacts with said actuation mechanism through said container so that when said actuation mechanism is moved in respect to said first and second position said cartridge is rotated and said container is stationary, said cartridge having a continuous length of storage film therein, wherein said actuation mechanism rotates said cartridge in only one direction causing said storage film to seal;
wherein said actuation mechanism comprises a rack having a plurality of protrusions adjacent one another along a horizontal plane to operatively engage said pinion of said cartridge, and wherein said rack engages said pinion of said cartridge to rotate said pinion and said cartridge when said rack moves linearly.
2. The waste disposal device according to claim 1 , wherein said actuation mechanism is operated by foot or hand, external to said outer surface of said container.
3. The waste disposal device according to claim 1 , wherein said container has a lid.
4. The waste disposal device according to claim 3 , further comprising a lever connecting said rack to said lid, and wherein said lid moves said lever to move said rack of said actuation mechanism from said first position to said second position of said actuation mechanism.
5. The waste disposal device according to claim 3 , wherein said lid is connected to a foot pedal.
6. The waste disposal device according to claim 3 , wherein said foot pedal opens said lid when said foot pedal is pressed.
7. The waste disposal device according to claim 3 , wherein said actuation mechanism moves to said first position when said lid is opened.
8. The waste disposal device according to claim 3 , wherein said rack skips over said pinion when said lid is opened.
9. The waste disposal device according to claim 3 , wherein said actuation mechanism moves to said second position when said lid is closed.
10. The waste disposal device according to claim 3 , wherein said rack engages said pinion when said lid is closed.
11. The waste disposal device according to claim 3 , wherein said cartridge rotates when said lid is closed.
12. The waste disposal device according to claim 11 , wherein said cartridge is spun one revolution when said lid is closed.
13. The waste disposal device according to claim 3 , wherein said actuation mechanism operatively engages said lid through levers connected to said outer surface of said container.
