This invention is related to waste disposal containers for collecting odorous material.
There is a need for an indoor storage container that eliminates the obvious side effects associated with storing unpleasant waste materials (e.g. organic waste, diapers, pet waste, fish, regular trash, and other smelly material) in one's living space, specifically odors, pests, and messes. This will help reduce the amount of half-filled plastic bags going to the landfill and reduce the frequency of taking out the trash. The invention is unique because it may automatically open and close a trash liner hands free, which of course is much more sanitary than removing tops and lids and fumbling with a soiled liner. It is also unique because it places a seal in the trash liner between uses, trapping the foul odor of offensive waste inside the liner while blocking out pests and pets. In addition, the invention's removable components make it adaptable for a variety of storage applications.
The invention of the present application is a waste receptacle comprising a body defining a cavity in which waste can be collected, a closing system to manage odor, and an actuator system to open and close the waste receptacle.
The closing system comprises a clamping mechanism housed inside the body. A bag or liner is placed inside the body with the opening of the bag disposed about the clamping mechanism. Actuation of the actuator system causes the clamping mechanism to open and close so as to open and close the opening of the bag. The closing system may further comprise a lid that opens and closes simultaneously with the clamping mechanism.
The actuator system may comprise a pair of pedal levers connected to the bottom of the waste receptacle, where depression of one pedal simultaneously opens the clamping mechanism and lid, and depression of the other pedal simultaneously closes the clamping mechanism and the lid.
The lid and pedal levers can be replaced with a hand actuator so that the clamping mechanism can be opened and closed with the hand rather than the feet using the pedals. The handle actuator can directly replace the lid and the pedal levers, if desired. In this configuration, the waste receptacle may be placed inside a cabinet.
A carrier may also be provided that can be housed in the body to support the waste collected in the bag. The carrier provides added support to transport the waste from the body to a desired location to be disposed or used as compost.
The detailed description set forth below in connection with the appended drawings is intended as a description of presently-preferred embodiments of the invention and is not intended to represent the only forms in which the present invention may be constructed or utilized. The description sets forth the functions and the sequence of steps for constructing and operating the invention in connection with the illustrated embodiments. It is to be understood, however, that the same or equivalent functions and sequences may be accomplished by different embodiments that are also intended to be encompassed within the spirit and scope of the invention.
The invention of the present application is directed towards a receptacle 100 that automatically opens and closes an inner lining or bag of the receptacle 100 to facilitate the collection of odorous waste, such as wasted food, pet waste, diapers, ordinary trash, and any other organic, odorous waste. A carrier 400 may also be provided to facilitate the transport of the waste to its desired location. Referring to
Body
The body 102 is preferably made of a rigid plastic material suitable for injection molding. The body 102 comprises opposing front and back walls 104, 106, and opposing right and left walls 108, 110 adjacent to front and back walls 104, 106 defining a top portion 112, a bottom portion 114 opposite the top portion 112, and a middle portion 116 therebetween. The front, back, right, and left walls 104, 106, 108, 110 terminate at a top perimeter edge 118 defining a top opening 120 at the top portion 112, and a bottom perimeter edge 122 opposite the top perimeter edge 118, the bottom perimeter edge 122 defining a bottom opening 124 at the bottom portion 114.
As shown in
The back wall 106 may comprise a recess 132 formed adjacent to the top perimeter edge 118 approximately midway between the right and left walls 108, 110. The back wall 106 may also comprise an extended lip 134 along the top perimeter edge 118. The extended lip 134 allows the lid 202 to be attached to the body 102. In some embodiments, a pair of pins 136a, 136b project laterally from the extended lip 134. These pins 136a, 136b can be used for mounting the lid 202 onto the body 102 in a rotatable manner. The recess 132 provides space for components of the closing system 200 to attach to the lid 202 for opening and closing the lid 202, as shown in
As shown in
As shown in
The front wall 104 further comprises a pair of cutouts 150a, 150b at the bottom portion 114 of the body 102. The cutouts 150a, 150b may be bilaterally arranged about the centerline of the front wall 104. The cutouts 150a, 150b are configured to receive components of the actuator system 300 as discussed in detail below.
As shown in
The base 152 may comprise a first hole 154 adjacent to the front wall 104 and a second hole 156 opposite the first hole 154 and adjacent to the back wall 106. The first and second holes 154, 156 provide inlets for components of the closing system 200 to enter into the main cavity 126. The base 152 further comprises bushings 350, 352, a stop 351, and cover 313 on the bottom side to hold and/or cover components of the actuator system 300 as described further below. Projecting upwardly onto the top side of the base 152 are a plurality of locating posts 115, 155 that allow the carrier 400 to be secured in place inside the body 102. The carrier 400 may, therefore, have divots on the bottom side to receive these posts 115, 155.
In some embodiments, partitions may extend downwardly from the base 152. The partitions may extend from the front wall 104 to the back wall 106. A first set of partitions may be adjacent to the right wall 108 and a second set of partitions may be adjacent to the left wall 110. The partitions provide additional support to the base 152. In some embodiments, projecting downwardly from the base 152 in between the two sets of partitions is a plurality of posts for mounting the actuator system 300. These posts may be threaded.
Closing System
As shown in
The back side of the lid 202 comprises an open slot 201 that faces away from the back wall 106 of the body 102. The open slot 201 receives the top end 219 of an extended arm 210 of the clamping mechanism 204 that allows for the lid 202 not only to be lifted or shut simultaneously with the clamping mechanism 204 if activated via the actuator system 300, but also to be lifted or shut independently without opening or closing the clamping mechanism 204. Thus, the open slot 201 allows the lid to disengage from the actuator system 300.
The lid 202 may have a ventilation system that comprises a vent 213. In the preferred embodiment, the vent 213 may not be in line with the surface of the lid 202 so as to slightly elevate or depress a portion 211 of the lid 202 relative to the remaining surface of the lid 202. The vent 213 contain at least two holes 217, allowing for air ventilation. The lid may also comprise a perforated flap 205 (shown in
The clamping mechanism 204 comprises a front lift arm 206 adjacent to the front wall 104 of the body 102 and a back lift arm 208 adjacent to the back wall 106 of the body 102. The front and back lift arms 206, 208 are substantially similar with one major difference being that the back lift arm 208 further comprises an extended arm 210 that attaches to the lid 202 or a hand actuator 301 as discussed below.
Both lift arms 206, 208 comprise a bottom end 212, 214, a top end 216, 218 opposite the bottom end 212, 214, and a bent post 220, 222 extending therebetween, respectively. The bottom ends 212, 214 are configured to attach to components of the actuator system 300. By way of example only, the lift arms 206, 208 are made from cylindrical rods. Therefore, the bottom ends 212, 214 may terminate as pins that can be inserted into a hole of a component of the actuator system 300 to connect to the actuator system 300 as discussed below.
The bent posts 220, 222 allow their respective bottom ends 212, 214 to be positioned adjacent to one of the side walls (in this example, the left wall 110) while allowing their respective top ends 216, 218 to align with the center line of the front and back wall 104, 106, respectively. Therefore, when properly installed the front and back lift arms 206, 208 extend upwardly from their respective bottom ends 212, 214, then bend towards the centerlines of the front and back walls 104, 106, respectively, then continue extending upwardly along their respective centerlines, terminating at their respective top ends 216, 218 centrally located between the right and left walls 108, 110. Each top end 216, 218 of the lift arm 206, 208 is operatively connected to their respective clamp actuator (front and back clamp actuators 224, 226).
The extension arm 210 may continue upwardly until a top end 219 of the extension arm 210 meets the back portion of the lid 202. The extension arm 210 may be attached to or abuttable against the back portion of the lid 202. The back portion of the lid 202 is rotatably attached to the back wall 106 of the body 102 via the pins 136a, 136b. In some embodiments, the extension arm 210 is slightly tilted towards the back wall 106. When actuated to lift upwardly, the extension arm 210 applies pressure against the back portion of the lid 202. In some embodiments, the pressure is an upward and rearward force. This causes the back portion of the lid 202 to rotate about the axis defined by the pins 136a, 136b. Rotation about this axis causes front portion of the lid 202 to rise up into the open configuration. In some embodiments, the clamp actuators 224, 226 may be integrally formed with their respective lift arms 206, 208. As the lift arms 206, 208 move up and down from movement of the actuator system 300, the clamp actuators 224, 226 similarly move up and down, thereby opening and closing the clamping mechanism 205 as discussed below.
In the preferred embodiment, movement of the clamp bars 258a, 258b are controlled by the clamp actuators 224, 226. The front and back clamp actuators 224, 226 may be identical. Therefore, only the front clamp actuator is described below, but the description is applicable to the back clamp actuator 226 as well. As shown in
As shown in
The front arms 254a, 254b are attached to the front wall 104 via their lateral pegs 264a, 264b. The lateral pegs 264a, 264b extend forwardly toward the front wall 104 from their respective transverse bases 260a, 260b. These lateral pegs 264a, 264b may fit into their respective holes 146a, 146b on the front wall 104 (shown in
The central pegs 266a, 266b fit inside the horizontal slots 228a, 228b of the clamp actuator 224, on their respective sides, in a slidable manner. Thus, the central pegs 266a, 266b are configured to slide back and forth within their respective horizontal slots 228a, 228b.
Similarly, with reference to
The back arms 256a, 256b are attached to the back wall 106 via their lateral pegs 274a, 274b similar to the way the front arms 254a, 254b are attached to the front wall 104. The lateral pegs 274a, 274b extend rearwardly toward the back wall 106 from their respective transverse bases 270a, 270b. These lateral pegs 274a, 274b may have holes 139a, 139b into which the posts 141a, 141b of the back placard 140 can be inserted to secure the clamp arms 252a, 252b to the back wall 106. The lateral pegs 274a, 274b are cylindrical so as to be rotatable within the holes 138a, 138b on the back wall 106 and/or about the posts 141a, 141b. Being fixed yet rotatable, these lateral pegs 274a, 274b become hinge points about which their respective clamp arms 252a, 252b can rotate.
The central pegs 276a, 276b, like the central pegs 266a, 266b of the front arm 254a, 254b, fit inside the horizontal slots 228a, 228b of the clamp actuator 226, on their respective sides, in a slidable manner, and are configured to slide back and forth within their respective horizontal slots 228a, 228b. Thus, as the clamp arms 252a, 252b move from the open and closed positions about their respective hinge points, the central pegs 276a, 276b slide within their respective horizontal slots 228a, 228b to accommodate such movements.
As shown in
In some embodiments, as shown in
The springs 265a, 265b may be identical; therefore, for convenience only, one spring 265a will be described. By way of example only, the spring 265a may be an elongated rod that is flexible enough to bend, but also has elastic properties to naturally tend toward a straightened configuration. The spring 265a may have free ends 266, 268 bent into hook-like configurations so as to be secured to opposing front arms 254a, 254b or opposing back arms 256a, 256b.
In this configuration, the elastic properties of the spring 265a will urge the free ends 266, 268 away from each other. When the clamp arms 252a, 252b are in the closed configuration, the free ends 266, 268 are below the pivot points. Therefore, urging the free ends 266, 268 away from each other causes the free ends 266, 268 to move under the pivot point thereby causing one clamp arm to rotate in the clockwise direction (in this example the left clamp arm 252a) and the other clamp arm to rotate in the counterclockwise direction (in this example the right clamp arm 252b), thereby urging the clamp arms 252a, 252b to be in the clamped configuration.
When the clamp arms 252a, 252b are in the open configuration, the free ends 266, 268 rotate to a position above the pivot points. Therefore, urging the free ends 266, 268 away from each other causes one clamp arm to rotate in the counterclockwise direction (in this example, the left clamp arm 252a) and the other clamp arm to rotate in the clockwise direction (in this example, the right clamp arm 252b), thereby urging the clamp arms 252a, 252b to be in the opened configuration. This spring 265a can be applied to the back arms 256a, 256b, front arms 254a, 254b, or both. Other mechanisms for urging the medial ends outwardly above and below the lateral pegs can be used, including tension springs, compression springs, and the like.
In some embodiments, bag clips 280a, 282a may be used to secure the bag to the clamp arms 252a, 252b. The bag clips 280a, 282a on opposing front arms 254a, 254b are mirror images of each other, but otherwise have the same structural features. Additional bag clips 280b, 282b are identical to bag clips 280a, 282a, respectively, can be used on the appropriate back arms 256b, 256a. For the sake of convenience, only one bag clip 280a and the front arm 254a will be described, but the features described apply to any of the bag clips 280a, 280b, 282a, 282b and their respective arms 254a, 256a, 254b, 256b. As shown in
In some embodiments, a lock may be provided to keep the lid 202 in the open configuration while the user is able to collect the waste for deposit into the receptacle 100 without having to maintain pressure on the pedal.
The Actuator System
The actuator system 300 is operatively connected to the closing system 200 so that the actuator system 300 can open and close the closing system 200.
In the preferred embodiment, as shown in
As shown in
In the preferred embodiment, the front and back rocker arms 306a, 306b are identical. The front rocker arm 306a performs a seesaw or rocking action to rotate the axle 310 about its longitudinal axis L1 in a clockwise and counterclockwise fashion. The front rocker arm 306a comprises a front socket 326a defining a longitudinal axis L2. The front socket 326a is configured to receive the forward end 322 of the axle 310 so that the longitudinal axis L2 of the front socket 326a is coaxially aligned with the longitudinal axis L1 of the axle 310. The outer surface of the axle 310 is configured to mate with the inner surface of the front socket 326a such that rotation of the front socket 326a about its longitudinal axis L2 causes rotation of the axle 310 about its longitudinal axis L1. For example, in the preferred embodiment, the outer surface of the axle 310 and the inner surface of the front socket 326a may have a hexagonal cross section of substantially the same size.
Extending bilaterally away from the front socket 326a approximately perpendicularly to the longitudinal axis L2 of the socket 326a is a front support arm 328a terminating at opposite terminal ends 330a, 332a. The front support arm 328a has a top edge 334a, a bottom edge 336a opposite the top edge 334a, a front face 338a adjacent to the top and bottom edges, and a back face 340a opposite the front face and adjacent to the top and bottom edges. The front socket 326a may protrude forwardly and/or rearwardly away from the front and/or back faces 338a, 340a of the front support arm 328a so as to jut out from the front and/or back face 338a, 340a. The top edge 334a comprises two connectors 342a, 344a to allow the support arm 328a to operatively connect with reciprocal connectors 343a, 343b on their respective pedal levers 302a, 302h at or near the terminal ends 330a, 332a. One of the terminal ends 332a also comprises a second connector mechanism 346a to operatively connect to the front lift arm 206. In the preferred embodiment, the second connector mechanism 346a may be a bore through which the bottom end 212 of the front lift arm 206 can be inserted.
In the preferred embodiment, the connectors 342a, 344a are arcuate nubs. The reciprocal connectors 343a, 343b on the pedal levers 302a, 302b are slots configured to receive the arcuate nubs so as to prevent the pedal levers 302a, 302b from slipping off of the support arm 328a. This arrangement can be reversed with the nubs 342a, 344a protruding from the pedal levers 302a, 302b and the slots 343a, 343b located on the support arm 328a. Any other type of fastening mechanism can be used to secure the pedal levers 302a, 302b to the front support arm 328a.
In the preferred embodiment, to facilitate the rocking action of the front rocker arm 306a, the bottom edge 336a may be curved upwardly moving towards the terminal ends 330a, 332a. In some embodiments, the bottom edge 336a may be faceted with flat surfaces that start out horizontal directly beneath the front socket 326a and progressively increase in angle relative to the floor moving towards the terminal ends 330a, 332a. For example, in the preferred embodiment, when the bottom edge 336a directly beneath the front socket 326a (referred to as the middle facet) is placed horizontally with the floor. A portion of the bottom edge moving laterally to the left (referred to as the left facet), and a portion of the bottom edge moving laterally to the right (referred to as the right facet) may each bend slightly upwardly such that the middle facet and the right facet form and obtuse angle, and the middle facet and the left facet form an obtuse angle. This allows the left facet to be parallel to the floor when the left pedal is depressed and the right facet to be parallel to the floor when the right pedal is depressed.
In the preferred embodiment, the back rocker arm 306b is identical to the front rocker arm 306a. Therefore, the back rocker arm 306b comprises a back socket 326b configured to receive the rearward end 324 of the axle 310 so that the longitudinal axis L3 of the back socket 326b is coaxially aligned with the longitudinal axis L1 of the axle 310. The outer surface of the axle 310 is configured to mate with the inner surface of the back socket 326b such that rotation of the axle 310 about its longitudinal axis L1 causes rotation of the back socket 326b about its longitudinal axis L3. The back rocker arm 306b has a back support arm 328b projecting laterally from the back socket 326b and terminating at opposite terminal ends 330b, 332b. In some embodiments, the back support arm 328b may only project laterally on one side. The back support arm 328b has a top edge 334b, a bottom edge 336b opposite the top edge 334b, a front face 338b adjacent to the top and bottom edges, and a back face 340b opposite the front face and adjacent to the top and bottom edges. The back socket 326b may protrude forwardly and/or rearwardly away from the front and/or back faces 338b, 340b of the back support arm 328b so as to jut out from the front and/or back face 338b, 340b. The top edge 334b may comprise two connectors 342b, 344b, but these are not necessary as the back rocker arm 306b does not connect with the pedals. One of the terminal ends 332b also comprises a second connector mechanism 346b to operatively connect to the back lift arm 206. In the preferred embodiment, the second connector mechanism 346b may be a bore through which the bottom end 214 of the back lift arm 208 can be inserted.
In the preferred embodiment, to facilitate the rocking action of the back rocker arm 306b, the bottom edge 336b may be curved upwardly moving towards the terminal ends 330b, 332b. In some embodiments, the bottom edge 336b may be faceted with flat surfaces that start out horizontal directly beneath the back socket 326b and progressively increase in angle relative to the floor moving towards the terminal ends 330b, 332b, like the front rocker arm 306a. Therefore, the back rocker arm 306b may have the same middle facet, left facet, and right facet described above for the front rocker arm 306a.
As shown in
At roughly the middle region between the front wall 104 and the back wall 106 are bilaterally arranged cylindrical bars 356a, 356b (such as a peg, dowel, pin, and the like) hanging below the bottom side of the base 152 with their longitudinal axes parallel to the front and back walls 104, 106. The proximal ends 318a, 318b of each lever arm 314a, 314b of the pedal levers 302a, 302b may each comprise a c-shaped opening 319a, 319b. The c-shaped openings 319a, 319b are configured to mate or snap-fit with their respective cylindrical bars 356a, 356b in a rotatable manner so as to define a hinge point at the proximal ends of the pedal levers 302a, 302b. With the pedal levers 302a, 302b mounted on the front rocker arm 306a at the distal ends 320a, 320b, and the proximal end 318a, 318b mounted to the base 152 via the c-shaped openings 319a, 319b, the pedal levers 302a, 302b are suspended off the floor and the distal ends 320a, 320b are capable of moving up and down while the proximal ends 318a, 318b remain fixed in location, but rotatable about their respective cylindrical bars 356a, 356b. A cover 313 may be provided to cover and protect the axle. The snap-fit connection makes it very easy to remove pedals in the event the user wants to use a hand actuator 301 to open and close the clamping mechanism.
To prevent the front rocker arm 306a from any translational shift that would cause the front rocker arm 306a to slide off the front bushing 350, a stop 351 may be positioned or formed adjacent to the front rocker arm 306a opposite the front bushing 350 so as to sandwich the front rocker arm 306a in between the front bushing 350 and the stop 351. The stop may be in the shape of an open arch as shown in
As shown in
In an alternate embodiment, a separate mounting bracket may be used that is attachable to the base. In such an embodiment, the mounting bracket may be generally a rectangular block having a front end, a back end opposite the front end, a right and left sides, the right and left sides opposite each other and adjacent to the front end and back end, and top and bottom sides opposite each other and adjacent to the front and back ends, and right and left sides.
The front and back ends each comprise a bushing (front bushing 350 and back bushing 352, respectively) configured to receive the socket 326a of the front rocker arm 306a and the socket 326b of the back rocker arm 306b, respectively. The outer surfaces of the each socket 326a, 326b are cylindrical in shape. The inner surfaces of each bushing 350, 352 are substantially similar to the outer surface of their respective sockets 326a, 326b, so that the sockets 326a, 326b are able to rotate about their longitudinal axis while sitting in their respective bushings 350, 352. In some embodiments, the back end of the back bushing 352 is slanted inwardly towards top edge relative to the back wall 106. This slant corresponds with the expanded bottom portion 114 of the body 102 so that the back end of the back bushing 352 will be flush with the back wall 106 of the body 102 when the back bushing 352 is fitted into the slot in the bottom portion 114 of the back wall 106.
In some embodiments, adjacent to the back bushing 352 on the top side is a slot. The slot is configured to receive the support arm 328b of the back rocker arm 306b when the socket 326b of the back rocker arm 306b is placed into the back bushing 352. Since the socket 326b of the back rocker arm 306b juts away from the back face 340b, when the socket 326b of the back rocker arm 306b is placed into the back bushing 352, the support arm 328b of the back rocker arm 306b fits in the slot at the back end of the mounting bracket so that the support arm 328b can move up and down freely. Since the socket 326a of the front rocker arm 306a juts rearwardly, mounting the socket 326a of the front rocker arm 306a on the front bushing 326a still allows the support arm 328a of the front rocker arm 306a to clear the mounting bracket so as to allow free movement of the rocker arms 306a, 306b without interference from the mounting bracket.
In the alternate embodiment of the mounting bracket, the top side of the mounting bracket comprises a flanged support face extending along the length of the mounting bracket. The support face allows the mounting bracket to be secured to the base 152 of the body 102. The support face may comprise a series of bores, preferably, threaded bores, corresponding with the posts on the protruding downwardly from the base 152. The posts can be used to secure the mounting bracket to the base 152. Other fastening mechanisms can be used as well. The mounting bracket is dimensioned so as to be hidden in the bottom portion 114 of the body 102.
Roughly in the middle region of the support face are bilaterally arranged slotted supports. The proximal ends of each pedal lever 302a, 302b comprise a cylindrical protrusion (such as a peg, dowel, pin, and the like) that is inserted into the one of the slotted supports. The cylindrical protrusions are free to rotate within the slotted supports. With the pedal levers 302a, 302b mounted on the front rocker arm 306a at the distal ends 320a, 320b, and the slotted supports at the proximal ends 318a, 318b, the pedal levers 302a, 302b are suspended off the floor and the distal ends 320a, 320b is capable of moving up and down while the proximal ends 318a, 318b remains fixed in place.
The center of the mounting bracket comprises a channel through the top side and along the length of the mounting bracket. The channel provides space to receive the axle 310 when the front and back rocker arms 306a, 306b are mounted on the mounting bracket with the axle 310. The channel allows the axle 310 to rotate freely about is longitudinal axis.
In some embodiments, the actuator system 300 may comprise an automated sensor or control (not shown) that detects a signal nearby to automatically open and close the lid 202 and clamping mechanism 204. By way of example only, the sensor or control may be operatively connected to gears and an electric motor that would rotate the axle 310, move the lift arms 206, 208, move the clamp arms 252a, 252b, move the clamp actuators 224, 226, move the lid 202, or move some other component controlling the closing system 200. The sensor may be a motion detector, heat sensor, touch sensor, a push button, and the like. This embodiment may be battery-operated or plugged into the wall socket.
Carrier
In some embodiments, the receptacle 100 may further comprise a carrier 400. As shown in
When used for composting, the carrier 400 may be used to hold compost tea, also known as leachate, which is essentially liquid run-off of decomposing compost that provides good nutrient for plants. If a user wishes to obtain the compost tea, he or she could purposefully leak the compost tea from the bottom of bag with compost in it into the tray 356 of the carrier 400. Using the carrier 400 provides a mess-free alternative to obtaining compost tea from a compost-filled bag in the receptacle. Even for any other types of trash, the carrier allows for an easy clean up if there is any leaking of waste from the bag or liner. In some embodiments, the base 152 may comprise guide posts 155 (see
In use, the carrier 400 sits inside the body 102 of the receptacle on top of the base 152. A bag is placed inside the body 102 on top of the tray 356. The perimeter edge defining the opening of the bag is folded over the clamp bars 258a, 258b. In some embodiments, adhesives, tacky silicone, and the like, on the clamp bars 258a, 258b may be used to hold the bag against the clamp bars 258a, 258b. In some embodiments, clips 280a, 280b, 282a, 282b are used to secure the bags. Any combination of these can also be used.
To open the receptacle 100, the user steps on the first pedal lever, for example, the right pedal lever 302b. Since the right pedal lever 302b is resting on the right side of the support arm 328a of the front rocker arm 306a, this causes the right terminal end 330a of the support arm 328a to move in a downward direction. Since the right side of the support arm 328a is attached to the socket 326a of the front rocker arm 306a, the socket 326a of the front rocker arm 306a rotates within the front bushing 350 in the clockwise direction. This causes the left terminal end 332a of the support arm 328a of the front rocker arm 306a to move upwardly.
Simultaneously, rotation of the socket 326a of the front rocker arm 306a causes the axle 310 to rotate in the same direction. Rotation of the axle 310 causes the back rocker arm 306b to rotate in the same direction causing left terminal end 332b of the support arm 328b of the back rocker arm 306b to lift upwards.
The upward movement of the left terminal ends 332a, 332b of the support arms 328a, 328b causes the front and back lift arms 206, 208 to move upwardly simultaneously. The lift arms 206, 208, being attached to their respective clamp actuators 224, 226, move the clamp actuators 224, 226 in an upward direction. Upward movement of the clamp actuators 224, 226 causes the central pegs 266a, 266b on the front arms 254a, 254b and central pegs 276a, 276b on the back arms 256a, 256b to move in an upward direction. Since the lateral pegs 264a, 264b on the front arms 254a, 254b are fixed against the front wall 104 from translational movement, and the lateral pegs 274a, 274b on the back arms 256a, 256b are fixed against the back wall 106 from translational movement, the clamp arms 252a, 252b rotate about the lateral pegs 264a, 264b, 274a, 274b. The right clamp bar 258b rotates in the clockwise and the left clamp bar 258a rotates in a counterclockwise direction about the lateral pegs 264a, 264b, 274a, 274b. This causes the clamp bars 258a, 258b to move away from each other, thereby opening the bag placed inside.
Simultaneously, the extension arm 210 on the back lift arm 208 also moves in an upward direction. Since the extension arm 210 is connected to or abuts against the lid 202, the lid 202 opens at the same time the clamp arms 252a, 252b move apart. The user can now discard any waste into the bag. Pressing on the opposite pedal (left pedal 302a), moves each component in reverse, thereby simultaneously closing the clamp arms 252a, 252b and the lid 202. When the user is ready to discard the waste, the user can open the receptacle 100 as described above. The user can then grab the handles of the carrier and carry the waste to the desired location for proper disposal.
The waste receptacle 100, and any components thereof, can generally be made using materials such as plastic, metal, wood, or any combination thereof. For example, injection molding techniques may be used to fabricate various components of the invention.
