The lifting mechanism is configured to lift or raise the parts tray within the bin as associated material located on the parts tray is selectively removed. ## Claims ### Claim 1 A self-leveling bin assembly comprising: a docking station; a bin received in or on the docking station; a parts tray movably received in the bin; and a lifting mechanism provided as part of the docking station and configured to lift the parts tray within the bin as associated material located on the parts tray is selectively removed, wherein the docking station includes a base having a bottom wall, a top wall, and at least one sidewall extending between the bottom wall and the top wall, the top wall has an opening, and a fence sized to receive the bin is affixed to and extends substantially about a perimeter of the top wall. ### Claim 2 (depends on 1) The self-leveling bin assembly of claim 1, wherein the bin is shaped complementary to the docking station, the bin includes a bottom wall having a lower opening aligned with the opening in the base and at least one sidewall extending from the bottom wall. ### Claim 3 (depends on 2) The self-leveling bin assembly of claim 2, wherein a height dimension of the bin sidewall is greater than a height dimension of the fence sidewall. ### Claim 4 (depends on 2) The self-leveling bin assembly of claim 2, wherein the bin sidewall includes mounts configured for stacking of multiple associated bins, the mounts shaped to not intrude into an interior of the bin. ### Claim 5 (depends on 2) The self-leveling bin assembly of claim 2, wherein the parts tray is shaped complementary to the bin, the parts tray includes a bottom wall and at least one sidewall extending from the bottom wall, the at least one sidewall is beveled shape so that the associated material contained within the bin moves away from the bin sidewall as the parts tray is raised within the bin by the lifting mechanism. ### Claim 6 (depends on 2) The self-leveling bin assembly of claim 2, wherein the lifting mechanism is adapted to substantially fit within the confines of the base and is at least partially positioned within the opening of the base. ### Claim 7 (depends on 6) The self-leveling bin assembly of claim 6, wherein the lifting mechanism is configured as an pneumatic spring or hydraulic spring which extends vertically through both the base opening and the bin opening into direct engagement with the parts tray. ### Claim 8 (depends on 1) The self-leveling bin assembly of claim 1, wherein the lifting mechanism is configured such that as the associated material is removed from the bin, the lifting mechanism exerts upward force to move the parts tray upward to maintain a top layer of the associated material within the bin at a predetermined level. ### Claim 9 (depends on 8) The self-leveling bin assembly of claim 8, wherein the lifting mechanism is configured such that as the associated material is added to the bin, the lifting mechanism exerts upward force to stabilize the parts tray within the bin to maintain the top layer of the associated material within the bin at the predetermined level. ### Claim 10 (depends on 1) The self-leveling bin assembly of claim 1, wherein a pair of elongated channel-shaped supports is mounted to a bottom wall of the bin, the elongated supports configured to allow the bin to move into and out of the docking station. ### Claim 11 A self-leveling bin assembly comprising: a bin for receiving associated material therein, the bin including a bottom wall having a lower opening and at least one sidewall; a parts tray seated on the bin bottom wall and movable within the bin, the parts tray including a bottom wall and at least one sidewall having a beveled shape; and a lifting mechanism provided beneath the bin and configured to lift the parts tray within the bin as associated material located on the parts tray is selectively removed, wherein the beveled shape of the parts tray sidewall moves the associated material contained within the bin away from the bin sidewall as the parts tray is raised within the bin by the lifting mechanism; wherein the lifting mechanism is provided as part of a docking station configured to support the bin, the docking station including a base having a bottom wall, a top wall, and at least one sidewall extending between the bottom wall and the top wall, the top wall has an opening for the lifting mechanism that is aligned with the lower opening of the bin. ### Claim 12 (depends on 11) The self-leveling bin assembly of claim 11, wherein the base further having a fence affixed to and extending substantially about a perimeter of the top wall, the fence sized to removably receive the bin. ### Claim 13 (depends on 11) The self-leveling bin assembly of claim 11, wherein the lifting mechanism is adapted to substantially fit within the confines of the base and is at least partially positioned within the opening of the base. ### Claim 14 (depends on 13) The self-leveling bin assembly of claim 13, wherein the lifting mechanism is configured as a pneumatic spring or hydraulic spring which extends vertically through both the base opening and the bin opening into direct engagement with the bottom wall of the parts tray. ### Claim 15 (depends on 14) The self-leveling bin assembly of claim 14, wherein the lifting mechanism is configured as a pneumatic spring, and the base includes a pneumatic fitting for connection to an associated external pressurized air source.
