The present invention relates to a waste container that includes a latch that prevents animals from being able to access an interior of the container but which can also allow cart lifters to lift and dump waste even if the lid remains latched.
Waste containers, such as for trash, recycling, or organic waste (compost), etc., often attract the interest of animals, such as rodents, dogs, raccoons, etc. Many containers include lids that latch, but some animals can pry under the lid and force the container open. For areas where the collection trucks include cart lifters, the containers might become damaged if they are lifted and dumped while latched.
A waste container includes a body having a base and a side wall extending upward from the base to define a container interior. A lid is hingeably secured to an upper portion of the side wall. A latch assembly selectively secures the lid to the side wall. The latch assembly includes a handle portion and a rotatable latch portion rotatable about an axis. The rotatable latch portion has a latch member that selectively interlocks with a hook portion.
In one example, at least one additional rotatable member is mounted to the latch assembly that is independently rotatable relative to the rotatable latch portion.
In one example, the waste container includes a release component that is independently operable of the latch assembly to unlatch the lid.
In one example, the lid includes at least one flexing channel to control flexing movement of the lid.
These and other features of the present invention can be best understood from the following specification and drawings, the following of which is a brief description.
A container, such as a roll out cart 10, according to one embodiment of the present invention is shown in
In
The rotatable members 44 help prevent a rodent from being able to rotate the handle 28 and the upper latch portion 21. If the rodent tries to push on the rotatable member 44 to rotate the handle 28, the rotatable member 44 will just rotate about the pin 48, thereby depriving the rodent of leverage on the handle 28. The rotating members 44 may also distract and occupy the rodent and thereby prevent the rodent from opening the lid 14.
Referring to
A latch member 64 protrudes downwardly and radially inwardly from an outer periphery of the larger diameter portions 60 of the lower latch portion 36. As shown, the latch member 64 may be arcuate. A forward facing hook 68 is formed adjacent an upper edge of the container body 12. The hook 68 engages the latch member 64 of the latch lower portion 36 thus, latching the lid 14 to the container body 12. The latch assembly includes the upper latch portion 21, lower latch portion 36 and hook 68. In the example shown, the hook 68 is integrally formed with the container body 12 as one piece.
In use, a user places waste in the container body 12 and rotates the handle 28 of the latch 20 about an axis generally transverse to the lid 14 to the locked position, in which the handle 28 is aligned with the locked indicia 30. This engages the latch member 64 with the hook 68 and latches the lid 14 to the container body 12.
On waste pick-up day, the user can wheel the roll out cart 10 to the curb and then rotate the handle 28 of the latch 20 to the unlocked position, where the hook 68 on the container body 12 would be aligned with one of the smaller diameter portions 62 of the lower latch portion 36. When the driver of the waste truck arrives, the driver can see whether the lid 14 is locked or unlocked. If the lid 14 is unlocked, the driver can use the cart lifter on the truck (e.g. using the grab bar and/or portions of the side walls 16) to lift the roll out cart 10 and dump the contents into the truck. If the driver sees that the handle 28 of the latch 20 is still in the locked position, the driver will not attempt to dump the cart 10 while the lid is latched. The driver or another worker can then rotate the latch 20 to the unlocked position to dump the cart 10. Another beneficial feature is that after the cart 10 has been dumped, as the lid 14 closes back down after being released by the cart lifter, and if the lid closing force is sufficient, the latch member 64 can slip over the hook 68 to re-latch the lid 14 without requiring any user input.
The upper latch portion 121 includes a base 140 and supports 142 extending upward from the base 140 to the handle 128. The carousel 170 includes a handle 172 extending across a diameter of a cylindrical body 174 that is rotatably mounted to the base 140 of the upper latch portion. Alternatively, or additionally, the handle 172 of the carousel 170 is rotatably mounted to the handle 128 of the upper latch portion 121. Fins 176 protrude outwardly from the cylindrical body 174. Openings 178 may be formed through the cylindrical body 174.
As shown in
In
The side wall 216 includes a street facing or front portion 216a, a first side portion 216b, a second side portion 216c, and a rear portion 216d. In this example configuration, the lid 214 is hinged to the rear portion 216d and the latch assembly 220 is positioned adjacent one of the edges of the lid 214 near one of the side portions 216b or 216c of the side wall 216. The latch assembly 220 includes a release component 280 that will allow a cart lifter to unlatch the latch 200 from a locked position when the user has left the latch assembly 220 in the locked position such that the cart 210 can be emptied without the driver having to leave the truck to unlock the lid 214. In the example shown, the release component 280 is mounted to the side wall 216b or 216c that is adjacent to the latch assembly 220 on the lid 214. The operation of the release component 280 will be discussed in greater detail below.
As shown in
The lower portion 236 is configured similarly to lower portion 36 described above. The lower portion 236 includes a latch member 264 that protrudes downwardly and radially inwardly from an outermost periphery of the lower latch portion 236.
The release component 280 is independently operable of the latch assembly 220 to unlatch the lid 214. The release component is capable of unlatching the lid 214 without having to rotate the latch 264. As shown in
The hook 268 engages the latch member 264 of the latch lower portion 236 thus, latching the lid 214 to the container body 212 as shown in the magnified view of the latch section in
The lid 214 includes a lip 296 that extends outwardly and then downwardly from an upper edge of the container body 212 (
In use, a user places waste in the container body 212 and rotates the handle 228 of the latch assembly 220 about an axis generally transverse to the lid 214 to the locked position, in which the handle 228 is aligned with the locked indicia 230. This latches the lid 214 to the container body 212.
On waste pick-up day, the user can wheel the roll out cart 210 to the curb and leave the handle 228 of the latch 20 in the locked position such that rodents will be prevented from unlatching the lid while the cart sits at the curb. When the driver of the waste truck arrives, it does not matter whether the lid 214 is locked or unlocked. The driver can use the cart lifter on the truck to grab opposing side wall portions 216b, 216c of the cart which will cause compression bar 282 to be compressed against the side wall 216. This will move the hook 268 out of engagement with the latch 264 such that the cart lifter can lift the cart 210, the lid 214 will open, and the contents in the container can be dumped into the truck.
The latch 320 is rotatable relative to the lid 314 and includes a handle 328 that is rotatable in a plane generally parallel to the lid 314. Locked indicia 330 and unlocked indicia 332 may be molded into the upper surface of the lid 314. When the handle 328 of the latch 320 is rotated into alignment with the locked indicia 330, this indicates that the latch 320 is locked and the lid 314 cannot be opened by a user gripping the lid in an attempt to rotate the lid 314 relative to the body 312. When the handle 328 of the latch 320 is rotated into alignment with the unlocked indicia 332, this indicates that the latch 320 is unlatched and the lid 314 can be opened.
As shown in
The upper latch portion 321 interfaces with a raised boss 370 that extends outwardly from an upper surface of the lid 314. The base 340 includes a bottom surface with a pair of downwardly extending prongs 372 having hooked ends 374. The boss 370 includes an opening 376 through which the prongs 372 extend.
The lower latch portion 336 includes a protrusion 378 that is received within the opening 376 via a bottom of the lid 314. The protrusion 378 includes a pair of slots or openings 380 that receive the prongs 372 such that the hooked ends 374 of the upper latch portion 321 can be snapped to the lower latch portion 336.
The lower surface of the base 340 also includes one or more raised ribs 382. In one example, the ribs 382 extend in a radial direction and are circumferentially spaced apart from each other relative to the opening 376 in the boss 370.
The lid 314 includes a mount area for the upper latch portion 321. In one example, the mount area comprises an upper surface of the boss 370, which includes a plurality of channels 384 that extend in a radial direction and which are circumferentially spaced apart from each other relative to the opening 376. As shown in
The ribs 382 create friction between the boss 370 and upper latch portion 321 such that the handle 328 does not spin freely. The area that allows the latch 320 to become disengaged, i.e. the second sub-set of channels 384b, is not as deep as the other sub-set of channels 384a. Thus, a slip point is provided such that if a rodent is pulling the handle 328, the handle will slide easily pass the unlocking areas and jump back into one of the locked areas.
In the example shown in
The second channel 490b comprises a flexing channel that is formed to extend at least partially about a boss portion 470 formed within the lid 414 for a latch 420. The latch 420 can comprise any of the latch configurations described above. The flexing channels 490a, 490b combat the lid from being leveraged open by a handle 428 of the latch 420. The channels keep the corners opposite of the handle 428 from pulling up when the handle 428 is being pulled.
While embodiments of the invention have been illustrated and described, it is not intended that these embodiments illustrate and describe all possible forms of the invention. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention.
