Pallet with tray stacking structure
View Patent ↗A pallet comprises a deck having an upper support surface; a plurality of support members depending from the deck; pallet stacking structure for retaining a second pallet stacked on the pallet, and tray retaining and stacking structure for retaining a tray on the pallet. The pallet stacking structure includes a plurality of first recessed regions formed in the upper support surface for receiving support members of a second pallet stacked on the first pallet. The tray retaining and stacking structure includes a plurality of second recessed regions formed in the upper support surface of the pallet for receiving the legs of a tray when the tray is supported on the pallet. The second recessed regions are formed within the outer boundaries of the first recessed regions and are deeper than the first recessed regions. The depths of the second recessed regions are slightly less than a length of the tray legs such that the bottoms of the tray legs touch the floors of the second recessed regions to transfer the weight of the trays downwardly through the tray legs and to the pallet rather than through the upper support surfaces of the tray.

tray retaining and stacking structure for retaining the at least one tray when supported on the pallet, the tray retaining and stacking structure including a plurality of tray stacking recessed regions formed within the outer boundaries of the pallet stacking recessed regions in the upper support surface of the deck such that the tray stacking recessed regions do not extend beyond the outer boundaries of the pallet stacking regions, the tray stacking recessed regions having a second depth greater than the first depth of the pallet stacking recessed regions and being configured to receive the legs of the at least one tray when the at least one tray is supported on the deck of the pallet.
2. The pallet as set forth in claim 1 , wherein the tray stacking recessed regions each have a floor, the floors being configured to support the weight of the at least one tray through the tray legs when bottoms of the tray legs touch the floors.
3. The pallet as set forth in claim 1 , wherein the plurality of tray stacking recessed regions includes multiple recesses that are circular, semi-circular, or quarter-circular in shape.
4. The pallet as set forth in claim 1 , wherein the plurality of tray stacking recessed regions of the tray retaining and stacking structure comprises:
a circular-shaped recess near a center point of the upper support surface;
four semi-circular shaped recesses, each positioned near a midpoint of a side of the upper support surface; and
four quarter-circular shaped recesses, each positioned near a corner of the upper support surface.
5. The pallet as set forth in claim 1 , wherein the pallet stacking recessed regions are approximately 3/16″ deep.
6. The pallet as set forth in claim 1 , wherein the tray stacking recessed regions are approximately 0.60″ deep.
7. The pallet as set forth in claim 1 , wherein the pallet is formed of rotationally molded synthetic materials.
8. The pallet as set forth in claim 1 , wherein the tray retaining and stacking structure permits multiple trays to be stacked on the pallet and directs forces related to the weight of the trays, and parts held in the trays, downwardly through the tray legs and to the tray stacking recessed regions.
9. A pallet for supporting at least one tray having legs, the pallet comprising:
a deck having an upper support surface;
a plurality of support members depending from the deck;
pallet stacking structure for retaining a second pallet stacked on the pallet, the pallet stacking structure including a plurality of pallet stacking recessed regions formed in the upper support surface of the deck for receiving support members of the second pallet when the second pallet is stacked on the pallet deck, the pallet stacking recessed regions having a first depth and each having an outer boundary; and
tray retaining and stacking structure for retaining the at least one tray on the pallet, the tray retaining and stacking structure including a plurality of tray stacking recessed regions formed in the upper support surface for receiving the legs of the at least one tray when the at least one tray is supported on the pallet, wherein the tray stacking recessed regions are formed within the outer boundaries of the pallet stacking recessed regions such that the tray stacking recessed regions do not extend beyond the outer boundaries of the pallet stacking regions, the tray stacking recessed regions having a second depth greater than the first depth of the pallet stacking recessed regions, each tray stacking recessed region having a floor, the floors being configured to support the weight of the at least one tray through the tray legs when the bottoms of the tray legs touch the floors of the tray stacking recessed regions.
10. The pallet as set forth in claim 9 , wherein the tray stacking recessed regions include a plurality of recesses that are circular, semi-circular, or quarter-circular in shape.
11. The pallet as set forth in claim 9 , wherein the plurality of tray stacking recessed regions of the tray retaining and stacking structure comprises:
a circular-shaped recess near a center point of the upper support surface;
four semi-circular shaped recesses, each positioned near a midpoint of a side of the upper support surface; and
four quarter-circular shaped recesses, each positioned near a corner of the upper support surface.
12. The pallet as set forth in claim 9 , wherein the pallet stacking recessed regions are approximately 3/16″ deep.
13. The pallet as set forth in claim 9 , wherein the tray stacking recessed regions are approximately 0.60″ deep.
14. The pallet as set forth in claim 9 , wherein the pallet is formed of rotationally molded synthetic materials.
15. The pallet as set forth in claim 9 , wherein the tray retaining and stacking structure permits multiple trays to be stacked on the pallet and directs forces related to the weight of the trays, and parts held in the trays, downwardly through the tray legs and to the tray stacking recessed regions.
16. A pallet for supporting at least one tray having legs, the pallet comprising:
a deck having an upper support surface;
a plurality of support members depending from the deck;
pallet stacking structure for retaining a second pallet stacked on the pallet, the pallet stacking structure including a plurality of pallet stacking recessed regions fonned in the upper support surface of the deck for receiving support members of the second pallet when the second pallet is stacked on the pallet, the pallet stacking recessed regions having a first depth and each having an outer boundary; and
tray retaining and stacking structure for retaining the at least one tray when supported on the pallet, the tray retaining and stacking structure including a plurality of tray stacking recessed regions including a circular-shaped recess near a center point of the upper support surface, four semi-circular shaped recesses, each positioned near a midpoint of a side of the upper support surface, and four quarter-circular shaped recesses, each positioned near a corner of the upper support surface, the plurality of tray stacking recessed regions being formed in the upper support surface for receiving the legs of the at least one tray when the at least one tray is supported on the pallet, wherein the tray stacking recessed regions are formed within the outer boundaries of the pallet stacking recessed regions such that the tray stacking recessed regions do not extend beyond the outer boundaries of the pallet stacking recessed regions, the tray stacking recessed regions having a second depth greater than the first depth of the pallet stacking recessed regions, each tray stacking recessed region having a floor, the floors being configured to support the weight of the at least one tray through the tray legs when bottoms of the tray legs touch the floors of the tray stacking recessed regions.
