Pallet return assembly
A pallet return assembly includes at least one support member, a bracket member, a base member including a stopper member, and a lever that, when actuated, moves the base member and its stopper member from a pallet catch position to a pallet release position. In the pallet catch position, the stopper member catches a bottom of a pallet positioned on the roller tracks of the pallet bay and restricts the pallet from moving along the roller tracks. In the pallet release position, the stopper member no longer catches the bottom of the pallet positioned on the roller tracks and no longer restricts the pallet from moving along the roller tracks.
1 . A pallet return assembly comprising:
a first support member configured to be attached to a first load beam of a pallet bay;
a bracket member configured to be attached to the first support member and to at least one of a plurality of roller tracks of the pallet bay;
a base member including a stopper member extending generally upwardly therefrom; and
a lever coupled to a portion of the base member and configured to move between a pallet catch position and a pallet release position;
wherein, when the lever is in the pallet catch position, the base member is positioned such that a portion of the stopper member extending from the base member protrudes above a pallet-supporting surface of the roller tracks of the pallet bay and catches a bottom of a pallet positioned on the roller tracks and restricts the pallet from moving along the roller tracks; and
wherein, when the lever is in the pallet release position, the base member is positioned such that the portion of the stopper member extending from the base member is positioned below the pallet-supporting surface of the roller tracks of the pallet bay and no longer catches the bottom of the pallet positioned on the roller tracks and no longer restricts the pallet from moving along the roller tracks.
2 . The pallet return assembly of claim 1 , further comprising a second support member configured to be attached to the first load beam of a pallet bay, wherein the bracket member is configured to be attached to the second support member and interconnect the first support member and the second support member.
3 . The pallet return assembly of claim 1 , wherein, when the lever is in the pallet catch position, the lever is positioned above a top surface of the first load beam of the pallet bay and at a height that permits an operator to step on the lever from above to move the lever from the pallet catch position into the pallet release position.
4 . The pallet return assembly of claim 1 , wherein:
the bracket member is L-shaped and has a vertical portion and a horizontal portion;
the vertical portion of the bracket member is attached to the first support member by at least one fastener; and
the horizontal portion of the bracket member is attached to at least two of the plurality of roller tracks of the pallet bay.
5 . The pallet return assembly of claim 4 , wherein:
the horizontal portion of the bracket member is positioned above a top surface of the first load beam of the pallet bay such that the roller tracks attached to the horizontal portion of the bracket member are tilted; and
wherein a first end portion of the roller tracks attached to the horizontal portion of the bracket member is positioned higher than a second end portion of the roller tracks that is located opposite to the first end portion of the roller tracks and attached to a second load beam of the pallet bay located opposite the first load beam of the pallet bay.
6 . The pallet return assembly of claim 5 , further comprising a spacer positioned below the roller tracks to support a bottom-facing surface of the roller tracks, wherein the spacer is at least in part supported by a third load beam of the pallet bay located between the first and second load beams of the pallet bay.
7 . The pallet return assembly of claim 6 , wherein the spacer includes at least one vertical support member coupled to a horizontal support member having a length sufficient to simultaneously support the bottom-facing surface of each of the roller tracks of the pallet bay.
8 . The pallet return assembly of claim 1 , wherein:
a first portion of the base member is fixedly attached to at least two of the plurality of the roller tracks of the pallet bay; and
a second portion of the base member located opposite the first portion is movably coupled to the at least two of the plurality of roller tracks of the pallet bay.
9 . The pallet return assembly of claim 8 , wherein:
the first portion of the base member is fixedly attached to the at least two of the plurality of the roller tracks of the pallet bay via a first connecting member including at least two openings each configured to permit a fastener to pass therethrough and fixedly attach the first connecting member to the at least two of the plurality of roller tracks of the pallet bay; and
the second portion of the base member is movably coupled to the at least two of the plurality of roller tracks of the pallet bay via a second connecting member including at least two openings each configured to permit a fastener to pass therethrough and fixedly attach the second connecting member to the at least two of the plurality of roller tracks of the pallet bay.
10 . The pallet return assembly of claim 9 , wherein the first portion of the base member overlies a portion of the first connecting member and the second portion of the base member underlies a portion of the second connecting member.
11 . The pallet return assembly of claim 9 , wherein the base member is retained in the pallet catch position via a biasing force provided by at least one resilient member located below the base member.
12 . The pallet return assembly of claim 11 ,
wherein, in response to an application of a downward force on the lever, the lever and the second portion of the base member moves downwardly from the pallet catch position toward the pallet release position against the biasing force exerted by the at least one resilient member; and
wherein, in response to a removal of the downward force from the lever, the lever and the second portion of the base member move upwardly from the pallet release position toward the pallet catch position via the biasing force exerted by the at least one resilient member.
13 . The pallet return assembly of claim 11 , wherein:
the base member includes at least one opening configured to permit a fastener to pass therethrough, the fastener also passing through at least one opening in the second connecting member and through an opening in a third connecting member positioned below the base member, the fastener being fixedly attached to the third connecting member by a nut positioned below the third connecting member.
14 . The pallet return assembly of claim 13 , wherein the at least one resilient member is coupled to the fastener such that the at least one resilient member is permitted to compress and expand along a shaft of the fastener between the base member and the third connecting member.
15 . The pallet return assembly of claim 13 , wherein the second portion of the base member is attached to the lever via a fourth connecting member, and wherein the fourth connecting member partially underlies the lever and partially overlies the second portion of the base member.
16 . The pallet return assembly of claim 1 , wherein the stopper member is coupled to the base member via a strengthening member the restricts the stopper member from bending relative to the base member.
