DETAILED DESCRIPTION

FIGS. 1-3 illustrate an example roll-out cart 20. The roll-out cart 20 includes a body portion 22 forming a receptacle for receiving materials, such as debris or household waste. Because the cart 20 can store household waste, which can include food scraps, the cart 20 can attract animals when stored outside or left by the roadside for pick up. To prevent access into the cart 20, the cart 20 includes a lid 24 that is pivotably attached a hinge 26. The cart 20 also includes a handle 28 fixed to the body portion 22 that incorporates the hinge 26 and allows a user to maneuver the cart 20. A lock assembly 30 allows for selective access into a receptacle formed by the body portion 22 of the cart 20. In the illustrated example, the lock assembly 30 includes a pair of hasps 32 fixed relative to the lid 24 and a lock 34 fixed relative to the body portion 22 for receiving the hasps 32 to prevent the lid 24 from pivoting about the hinge 26.

One feature of having the pair of hasps 32 securing the lid 24 to the body portion 22 is improved durability. In particular, the lid 24 is secured to the body portion 22 along the side with the hinge 26 as well as two locations along an opposite side of the body portion 22 from the hinge 26. Also, having the pair of hasps 32 reduces an amount that the lid 24 can be pried open from flexing the lid 24 while the hasps 32 are in a locked position.

As shown in FIGS. 1-3, the lock 34 includes an elongated body portion having a pair of catches 40, or hasp receptacles, located adjacent opposing ends of the body portion 36 of the lock 34. One feature of the separation of the pair of catches 40 is improved rigidity of the lid 24 when locked as discussed above. The body portion 36 also includes a pair of fastener openings 38 located at opposing ends to secure the lock 34 to an interior surface of the body portion 22 of the cart 20. The catches 40 are each pivotable about a pivot axis P that is transverse or perpendicular to a sidewall of the body portion.

In the illustrated example, the lock 34 includes a pair of actuators 44 in electrical communication with a power source 46 and a controller 48. Each of the actuators 44 is located adjacent a corresponding one the catches 40. However, a single one of the actuators 44 could be mechanically connected to each of the catches 40 to cause the catches 40 to release. The controller 48 includes a microprocessor, memory, and a transmitter/receiver to communicate with a remote location R, such as a garbage collection vehicle, over a radio frequency (“RF”) to release the hasps 32 from each of a corresponding one of the catches 40.

Furthermore, each of the pair of actuators 44 could be gravity actuated such that the catches 40 remain in a locked position when the cart 20 is in an upright position and the catches move into an unlocked or released position when the cart 20 has tilted beyond a predetermined threshold. For example, the catches 40 would not move to a released or unlocked position until the cart 20 is at least partially inverted to simulate dumping by a garbage truck. Also, the catches 40 could remain locked when in a horizontal position, such as when tipped on its side by an animal trying to access the interior of the cart 20. Alternatively, a manual release 42 could be located on an exterior side of the body portion 22 adjacent the lock 34 to allow the lock 34 to be manually released.

FIGS. 4-7 illustrate another example roll-out cart 120. The roll-out cart 120 is similar to the cart 20 except where described below or shown in the Figures. Similar numbers are used between the cart 120 and the cart 20 with the addition of a leading 1. The roll-out cart 120 includes a body portion 122 forming a receptacle and a lid 124 that pivots about a hinge 126 to provide access into the cart 120. The cart 120 also includes a handle 128 fixed to the body portion 122 that incorporates the hinge 126 and allows a user to maneuver the cart 120.

A lock assembly 130 includes a claw 132, or a catch, and a lock 134 both located on the lid 124 for selectively allowing the lid 124 to pivot on the hinge 126 to provide access into the cart 120. In the illustrated example, the lock assembly 130 is located on an exterior side of the lid 124. The claw 132 is selectively moveable relative to the lock 134 between an extended or unlocated position as shown in FIGS. 6 and 7 or a retracted or locked position as shown in FIGS. 4 and 5.

In the illustrated example, the claw 132 includes a central leg 132A that is moveable into and out of the lock 134, a pair of side protrusions 132B that extend laterally from the central leg 132A, and a central protrusion 132C that extends from a midportion of the central leg 132A. Each of the side protrusions 132B and the central protrusion 132C include a hook 136 at a distal end forming a recessed channel.

The hooks 136 extend around a perimeter of the lid 124 and around a lip 141 (FIG. 7) on the body portion 122 to fix the lid 124 to the body portion 122. When the claw 132 is moved to a retracted or locked position (FIGS. 4 and 7), the hooks 136 extend around the lid 124 and under the lip 141 on the body portion 122 to prevent the lid 124 from pivoting on the hinge 126. One feature of having the claw 132 with the hooks 136 is to provide improved durability of the lid 124 by having multiple latching points between the lid 124 and the body portion 122.

The claw 132 and lock 134 are located in a recessed portion 125 or channel on the lid 124 to prevent the claw 132 and lock 134 from protruding above an upper surface of the lid 124. One feature of this configuration is to allow other objects to be stacked on top of the lid 124 without impeding movement of the claw 132 or making objects stacked thereon unstable.

Additionally, the recessed portion 125 includes a forward retention lip 150F that partially surrounds a forward edge of the claw 132 when in an extended position and an aft retention lip 150A that partially surrounds an opposing or aft edge of the claw 132 when the claw 132 is in the retracted position. The forward and aft retention lips 150F, 150A prevent the claw 132 from being pried from the recessed portion 125 to grant unauthorized access into the cart 120.

To selectively grant or prevent movement of the claw 132, the lock 134 includes a pair of opposing latch release buttons 142 in corresponding recesses 145 in a body portion 147 of the lock 134. The claw 132 can be released from the lock 134 by depressing the buttons 142 simultaneously or individually depending on a desired level of security. Additionally, the claw 132 can be spring loaded into the lock 134 to cause the claw 132 to spring to an extended position when released. This spring movement also provides confirmation to a user that the buttons 142 have been sufficiently activated to release the claw 132. One additional feature of having the buttons 142 located in the recesses 145 is improved tamper resistance from animals. Also, the inward pinching motion required to actuate the buttons 142 makes it more difficult for smaller animals to engage the buttons 142 and the recesses 145 makes it harder for larger animals to reach.

In the illustrated example, the lock 134 includes at least one actuator 144 in electrical communication with a power source 146 and a controller 148 having a microprocessor, memory, and a transmitter/receiver to communicate with a remote location, such as a garbage collection vehicle, over a radio frequency to release the claw 132. Furthermore, the actuator 144 could be gravity actuated such that the lock 134 remains in a locked position when the cart 120 is in an upright position and in an unlocked or released position when the cart 120 has tilted beyond a predetermined threshold as described above.

FIGS. 8-11 illustrate another example roll-out cart 220. The roll-out cart 220 is similar to the cart 20 except where described below or shown in the Figures. Similar numbers will be used between the cart 120 and the cart 20 with the addition of a leading 2. The roll-out cart 220 includes a body portion 222 forming a receptacle and a lid 224 that pivots about a hinge 226 to provide access into the cart 220. The cart 220 also includes a handle 228 fixed to the body portion 222 that incorporates the hinge 226 and allows a user to maneuver the cart 220.

A lock assembly 230 allows for selective access into the cart 220. The lock assembly 230 includes a pair of hasps 232 fixed relative to the lid 224 and a lock 234 fixed relative to the body portion 222 for receiving the hasps 232 to prevent the lid 224 from pivoting about the hinge 226. In the illustrated example, the hasps 232 are buckle styled as opposed to loop styled with the hasps 32. One feature of having the pair of hasps 232 securing the lid 224 to the body portion 222 is improved durability by securing the lid 224 to the body portion 222 along the hinge 226 as well as at two locations along an opposite side of the body portion 222 from the hinge 226. Also, having the pair of hasps 232 reduces an amount that the lid 224 can be pried open from flexing the lid 224 while the hasps 232 are still in a locked position. Furthermore, the lid 224 includes a plurality of ribs 225 that increase the rigidity of the lid 224 to prevent it from deforming.

As shown in FIGS. 8-11, the lock 234 includes a central body portion 235 having a pair of latches 240 or catches spaced from the central body portion 235 and aligned to receive the hasps 232 on the lid 224. The central body portion 235 also includes a pair of release buttons 242 located in corresponding recesses 245 to selectively release a corresponding one of the hasps 232 from one of the latches 240. Each of the buttons 242 are connected to the latches 240 through a mechanical linkage 260, such as an actuator cable. The central body portion 235 and the latches 240 are located on an exterior side of the body portion 222 with the latches 240 positioned in a recessed area formed by a lip 241 in the body portion 222. The lip 241 includes openings to allow the hasps 232 to pass through the lip 241 and reach the latches 240. The lip 241 also provides protection for the pair of latches 240.

In the illustrated example, the lock 234 includes at least one actuator 244 in electrical communication with a power source 246 and a controller 248 having a microprocessor, memory, and a transmitter/receiver to communicate with a remote location, such as a garbage collection vehicle, over a radio frequency to release the hasps 232 from the latches 240. Furthermore, the actuator 244 could be gravity actuated such that the latches 240 remain in a locked position when the cart 220 is in an upright position and in an unlocked or released position when the cart 220 has tilted beyond a predetermined threshold as described above.

FIGS. 12-15 illustrate another example roll-out cart 320. The roll-out cart 320 is similar to the cart 20 except where described below or shown in the Figures. Similar numbers will be used between the cart 320 and the cart 20 with the addition of a leading 3. The roll-out cart 320 includes a body portion 322 forming a receptacle and a lid 324 that pivots about a hinge 326 to provide access into the cart 320. The cart 320 also includes a handle 328 fixed to the body portion 322 that incorporates the hinge 326 and allows a user to maneuver the cart 320.

The locking assembly 330 includes a retractable belt 331 having a hasp 332 at the distal end with a buckle style. The retractable belt 331 can be retracted into a belt housing 335 located on a first lateral side of the body portion 322. A lock 334 is located on an opposite lateral side of the body portion 322 from the belt housing 335 to selectively release the hasp 332 and allow the lid 324 to pivot on the hinge 326 to provide access into the cart 320.

When the hasp 332 on the retractable belt 331 is located in the lock 334, the belt 331 is located in a recessed portion 325 or channel on the lid 324 to prevent the belt 331 from protruding above an upper surface of the lid 324 or sliding off of the lid 324. One feature of this configuration is to allow other objects to be stacked on top of the lid 324 without impeding movement of the belt 331.

To selectively grant or prevent movement of the belt 331, the lock 334 includes a pair of opposing latch release buttons 342 in corresponding recesses 145 in a body portion 347 of the lock 334. The hasp 332 can be released from the lock 334 by depressing the buttons 342 simultaneously or individually depending on a desired level of security. Additionally, the hasp 332 can be spring loaded into the lock 334 to cause it to move out of the lock 334 when released. This movement also provides confirmation to a user that the buttons 342 have been sufficiently activated to release hasp 332. One additional feature of having the buttons 342 located in the recesses 345, is improved tamper resistance from animals, such as bears. Also, the inward pinching motion required to actuate the buttons 342 makes it more difficult for smaller animals to engage the buttons 342.

In the illustrated example, the lock 334 includes at least one actuator in electrical communication with a power source 346 and a controller 348 having a microprocessor, memory, and a transmitter/receiver to communicate with a remote location, such as a garbage collection vehicle, over a radio frequency to release the hasp 332. Furthermore, the actuator 344 could be gravity actuated such that the lock 334 remain in a locked position when the cart 320 is in an upright position and in an unlocked or released position when the cart 320 has tilted beyond a predetermined threshold as described above.
