Definitions

  • the present invention is directed to a latch for closing a container lid to a container, and a system and a method for opening a latched container.
  • Containers such as garbage containers for homes are known in the art.
  • the containers have a container body.
  • wheels may be provided at a lower corner of the container body.
  • a lid is rotatably affixed to the container to rotate between a first open position and a second closed position.
  • latches are provided. These latches are usually metal pieces.
  • a metal piece formed as a rod is pivotally mounted to the lid.
  • the rod forms a general U-shape in which a first end of the rod is mounted to the lid and the second opposed end of the wire is also mounted to an opposed position on the lid so that the U-shaped rod is pivotally mounted to the lid.
  • the base of the U may be formed as a handle.
  • the sections between the handle and the respective rod ends form, at least in part, an engaging portion for engaging a lip of the container body.
  • engaging portions of the latch engage a portion of the container body locking the lid against the container body.
  • the handle is pulled to rotate the latch from the second position releasing the lid from the container body allowing the lid to be rotated into an open position.
  • a container comprising a body and a lid rotatably affixed to the body so as to be selectively rotated between a first open position and a second closed position.
  • a latch has a first end adapted to be rotatably affixed to the lid.
  • a second end is adapted to engage the body. The first end is connected to the second end by an arched member, the arched member capable of flexure when a force is applied at a concave surface of the arched member.
  • a lifting arm for emptying a container into a truck comprising an arm having a proximal end, adapted to be affixed to a truck, and a distal end, a manipulating assembly affixed to the arm at the distal end, the manipulating assembly including a grabber member for engaging the container when disposed within the grabber member; a moving member capable of moving between a first position and a second position, the moving member unlatching the container held by the grabber member by moving from the first position to the second position.
  • a method for unlatching a latched container comprising providing a lifting arm for lifting the latched container; moving the latched container from a first position to a second position with the lifting arm; an unlatching the container by moving the container from the first position to the second position.
  • a system for unlatching a latched container comprising a container having a body; a lid rotatably affixed to the body and movable between a first position and a second position; and a latch pivotably mounted on the lid for selectively locking the lid in a closed position, the latch having a first member adapted to be pivotably mounted to the lid, a second member adapted to selectively engage a projection on the body; and an arched member connecting the first member to the second member; and a lifting arm comprising an arm having a proximal end adapted to be affixed to a truck and a distal end; a manipulating assembly affixed to the arm at the distal end, the manipulating assembly including a grabber member for engaging the container when disposed within the grabber member; a moving member capable of moving between a first position and a second position, the moving member unlatching the container by moving from the first position to the second position.

  • Figure 14 is a side elevation view of a system according to an embodiment of an aspect of the invention, with the container disposed between the first and second position.
  • Container 10 includes a container body 12 having a projection in the form of an upper rim 22 extending about a top, and the opening formed at the top of body 12. Support members 16 extend from the rim 22. A handle 18 is supported by support members 16 spaced away from housing 12.
  • Wheels 26 are affixed to housing 12 as in a manner known in the art so that container 10 is mobile.
  • rim 22 is provided by way of exemplary, but nonlimiting embodiment. Any projection from body 12 is contemplated by the present invention. Rim 22 may merely be a ridge, a lip, a platform, or a projection capable of being engaged by a latch 30. Support member 16 may also extend from body 12, rather than rim 22.
  • a lid 14 sized to cover an opening (not shown) of body 12 is rotatably disposed on body 12.
  • Lid 14 is formed with wings 20 for rotatably engaging handle 18 as known in the art. In this manner, lid 14 may be moved from a first closed position, as seen in the figures, about the pivot provided by handle 18 to an open position (not shown) to allow access to the container body 12.
  • a pivot 24 is formed within lid 14. In a nonlimiting embodiment, pivot 24 is at an edge of lid 14 opposed to an edge from which lid 14 is rotatably affixed to body 12.
  • Latch 30 is pivotally disposed about pivot 24 and is adapted to engage a projection such as that formed by rim 22 to lock lid 14 in the closed position. Accordingly, latch 30 is rotatable between a first open position, as shown in Figure 8 , which allows rotation of lid 14 and a closed position, as shown in Figure 9 , which locks the lid 14 to body 12 in the closed position.
  • Latch 30 includes a first member 32 which is a pivot member.
  • First member 32 is formed with a receiving portion, in an exemplary but nonlimiting embodiment, an opening 34 therein, adapted to receive pivot 24 of lid 14.
  • Latch 30 includes a second member 36 acting as a handle.
  • An arch member 40 connects first member 32 with second member 36.
  • Handle portion 36 is formed with a catch 38.
  • Catch 38 is a projection adapted to engage a projection of housing body 12 such as rim 22.
  • Pivot member 32, handle 36, and arch member 40 are formed as a unitary construction; preferably formed of a plastic material.
  • Arch member 40 is flexible such that a force applied at a convex surface 48 of latch 30 will deflect arch member 40 flattening arch member 40 to lengthen latch 30.
  • Arch 40 has sufficient resiliency that it will substantially return to its original shape upon removal of the force at convex surface 48 of arch portion 40.
  • a plurality of support archs 44 extend along convex surface 48 between arch member 40 and pivot member 32.
  • a second set of support members 46 comprised of one or more support archs, in a nonlimiting exemplary embodiment, extend along a concave surface of arched member 40, and may extend from the handle portion of second member 36 to the pivot portion of second member 32.
  • An opening 42 may be provided in second member 36 adjacent catch 38.
  • Catch 38 may be any shape capable of engaging a projection from housing 12, such as rim 22 while also being dimensioned to allow for disengagement by flexure of handle 36 as will be discussed below.
  • latch 30 is pivotally mounted to lid 14. Pivot 24 is received within opening 34 of pivot 32 of latch 30. To lock container 10, latch 30 is pivoted from a first open position ( Figure 8 ) in a direction of arrow C to an intermediate position ( Figure 10 ).
  • latch 30 is dimensioned so that catch 38 is positioned along latch 30 so that when no force is applied to latch 30, catch 38 is disposed at a position in which it does not engage rim 22, in this instance the position is above a bottom surface 23 of the projection provided by rim 22.
  • latch 30 is lengthened so that catch 38 moves below bottom surface 23 of rim 22 to engage rim 22.
  • Latch 30 is resilient such that once the force in the direction of arrow A is removed, latch 30 will substantially return to its original position.
  • catch 38 engaging rim 22 prevents complete return, and therefore the restorative force of latch 30 keeps latch 30 in the closed position by the force applied by catch 38 against lip 22.
  • a force in the direction of arrow A not only extends the length of latch 30, but also continues to move handle 30 in the direction of arrow C so that it is the action of pressing against latch 30 at arch member 40 which closes and locks the container as shown in Figures. 1 and 9 .
  • handle portion 36 is slightly curved in that portion of second member 36, which extends from catch 38.
  • Handle 36 is curved in a direction opposed to the curve of arch member 40, and in an embodiment, to a lesser extent (more obtuse curve) than the curve of arched member 40. This facilitates applying a force in direction of arrow B to latch 30 at handle portion 36. Applying a force at handle portion 36 pulls catch 38 away from rim 22 releasing latch 30 allowing rotation into the open position shown in Figure 8 .
  • the surface of catch 38 may be rounded or cammed to allow catch 38 to slide along rim 22 as it is released rather than requiring movement of handle portion 36 sufficient to rotate catch 38 to clear rim 22 or to flatten catch 40.
  • Latch 30 must be sufficiently rigid so as to maintain a grip about pivot 24 and sufficiently rigid along its length to maintain catch 38 in position to prevent opening of lid 14.
  • latch 30 must be sufficiently flexible to allow flattening of latch 30 without the need for excessive force, i.e. not beyond a manual force easily applied by an ordinary person and to allow handle 36 sufficient movement to allow catch 38 to either be deflected by rim 22 or disengaged by rim 22.
  • Latch 30 also exhibits restorative properties so that once released, latch 30 returns to its original shape.
  • latch 30 must maintain these properties across a temperature range from -30°C to 30°C.
  • latch 30 is unitary nylon construct.
  • a slit 35 is formed within pivot member 32. Slit 35 mates with a projection (not shown) formed on lid 14. Slit 35 is off centered along the axis of second member 32 which prevents mistaken installation of latch 30. Latch 30 will only fit about pivot 24 of lid 14 when slit 35 is aligned with the projection guaranteeing normal orientation.
  • System 100 includes a container 10 having a latched lid in which a portion of the latch extends below or beyond the lid, such as latch 30 by way of nonlimiting example and a lifting arm constructed as robotic arm 120, by way of nonlimiting example.
  • Robotic lifting arm 120 includes a proximal end 122 adapted to be affixed to a truck (not shown) as known in the art.
  • Robotic arm 120 has a first section 124 extending from proximal end 122 and a second section 126 extending from first section 124 at an angle.
  • Lifting arm 120 is capable of a range of motion as known in the art to enable lifting and dumping of a full container.
  • a manipulating assembly 140 is affixed to a distal end 128 of robotic lifting arm 120.
  • Manipulating assembly 140 includes a motor block 141 for housing a motor.
  • a grabber assembly which, by way of nonlimiting example, includes grabber members 142a, 142b extending from opposed sides of the motor block 141 and move between a first, open, position and a second, closed or pincing, position under the control of a motor (not shown) typically housed in the motor block 141. It is understood that through gearing the motor may be housed anywhere along system 100.
  • Grabber members 142a, 142b when in the closed or second position surround and grab the body 12 of the container 10 (see Figures 12 an 13).
  • grabber members 142a, 142b Another structure which grabs to lift the container may be substituted for the grabber members 142a, 142b.
  • the container 10 When grasped, in accordance with the invention, the container 10 is captured by the grabber members 142a, 142b such that the latch 30 is substantially in facing relationship with the robot lifting arm 120.
  • An unlatching member 144 includes a guide member 146, which is a pathway or chute extending from the grabber members 142a, 142b towards the second arm section 126 for example.
  • a moving member 147 is disposed within the guide member 146 and is capable of moving within the guide member 146, under the control of gravity, from a first position away from the latch 30 to a second position towards and/or beyond the latch 30.
  • the moving member 147 may include wheels, 148a, 148b as shown, to facilitate movement within the guide member 146 of the moving member 147.
  • wheels are used as an exemplary, nonlimiting embodiment and may be omitted by utilizing low friction elements such as TeflonTM or lubricant such as oil, grease or silicon spray, or any combination thereof so long as the moving member 147 is capable of substantially consistent movement at a speed sufficient to dislodge the latch 30 as the moving member 147 moves from the first position to the second position as will be described below.
  • a finger member 149 extends from the moving member 147 outside of the path formed by the guide member 146 and is sufficiently sized so that to engage a latch, such as the latch 30 as the moving member 147 moves from the first position to the second position.
  • Figures 12 and 14 Operation of the system 100 is illustrated by Figures 12 and 14 for example, which have substantially the same frame of reference, and show the arm 120 as it moves through an arc generally defined by arrow G between a start position to at least a dumping position.
  • Gravity, acting on the moving member 147 causes the moving member 147 to move substantially in the direction of arrow H as the lifting arm 120 moves.
  • the finger member 149 moves in the direction of arrow H and engages the latch 30.
  • the finger member 149 engages the handle portion 36 to flex the handle portion 36 and disengage the latch 30 as described above.
  • the system may work with any lid and latch in which contacting a lower extremity of the latch by moving member 147 causes disengagement of the latch.
  • a latch sufficiently strong to resist animal break in may be utilized without the need for the operator of the truck to manually open each container prior to dumping.
  • a lifting arm which utilizes gravity to move an unlatching mechanism from a first position to a second position; the second position being at least an unlatching position, a simple mechanical structure is provided to consistently unlatch latched containers.
  • a plastic latch rotatably affixed to the lid of the container and capable of flexure to engage the body of the container and a disengaging the handle, a simple structure capable of being mass produced at low cost is provided for removably latching the container in a manner that prevents animal break in.
