Abstract

A modular stack includes a plurality of baskets including at least a first basket and a second basket. The second basket is configured to be stacked on the first basket such that the first and second baskets occupy a same footprint. The first and second baskets each include a base frame that is substantially rectangular. The first and second baskets also each include a bottom extending across a lower portion of the base frame. The first and second baskets also each include one or more cross-members extending over the bottom from a first side of the base frame to a second side of the base frame. The first and second baskets also each include a side plate extending upward from the first side. The side plate is connected to the base frame and the one or more cross-members.

Claims (33)

1 . A modular stack, comprising:

a plurality of baskets including at least a first basket and a second basket, wherein the second basket is configured to be stacked on the first basket such that the first and second baskets occupy a same footprint, and wherein the first basket comprises:

a base frame that is substantially rectangular;

a bottom extending across a lower portion of the base frame;

one or more cross-members extending over the bottom from a first side of the base frame to a second side of the base frame;

a side plate extending upward from the first side, wherein the side plate is connected to the base frame and the one or more cross-members,

a post extending vertically from a corner of the base frame; and

a guide at an upper end of the post, wherein the guide of the first basket is configured to be inserted into a lower end of a post of the second basket.

2 . The modular stack of claim 1 , wherein the first basket and the second basket are configured to be lifted independently of one another.

3 . The modular stack of claim 1 , wherein the guide comprises a first plate and a second plate that are substantially perpendicular to one another, wherein the first plate defines a first slot for receiving a portion of the second plate, and wherein the second plate defines a second slot for receiving a portion of the first plate.

4 . The modular stack of claim 3 , wherein upper ends of the first and second plates of the guide of the first basket are tapered to facilitate insertion into the lower end of the post of the second basket, and wherein the guide of the first basket comprises a landing stop that is configured to engage the upper end of the post of the first basket to prevent the guide of the first basket from falling through the post of the first basket.

5 . The modular stack of claim 1 , wherein the bottom of the first basket is solid, and wherein a bottom of the second basket is non-solid and defines one or more openings therein to reduce a weight thereof.

6 . The modular stack of claim 1 , wherein the side plate extends less than a length of the first side.

7 . The modular stack of claim 1 , wherein the side plate extends upward less than a height of the basket of which it is a part.

8 . The modular stack of claim 1 , wherein the side plate defines at least two openings, wherein the at least two openings are positioned above the bottom, wherein the one or more cross-members extend from the at least two openings, and wherein the one or more cross-members are hollow to receive a connection for a lifting mechanism.

9 . The modular stack of claim 1 , wherein the second basket comprises:

a base frame that is substantially rectangular;

one or more cross-members extending from a first side of the base frame to a second side of the base frame;

a center support extending from a first end of the base frame to a second end of the base frame, and wherein the one or more cross-members are perpendicular to the center support.

10 . A modular stack, comprising:

a plurality of baskets including at least a first basket and a second basket, wherein the second basket is configured to be stacked on the first basket such that the first and second baskets occupy a same footprint, and wherein the first basket comprises:

a base frame that is substantially rectangular;

a bottom extending across a lower portion of the base frame;

one or more cross-members extending over the bottom from a first side of the base frame to a second side of the base frame;

a side plate extending upward from the first side, wherein the side plate is connected to the base frame and the one or more cross-members,

a post extending vertically from a corner of the base frame; and

a guide at an upper end of the post, wherein the guide of the first basket is configured to be inserted into a lower end of a post of the second basket, wherein the guide comprises a first plate and a second plate, wherein the first plate defines a first slot for receiving a portion of the second plate, wherein the second plate defines a second slot for receiving a portion of the first plate, wherein upper ends of the first and second plates of the guide of the first basket are tapered to facilitate insertion into the lower end of a post of the second basket, and wherein the guide of the first basket comprises a landing stop that is configured to engage the upper end of the post of the first basket to prevent the guide of the first basket from falling through the post of the first basket.

11 . The modular stack of claim 10 , wherein the bottom of the first basket is solid, and wherein a bottom of the second basket is non-solid and defines one or more openings therein to reduce a weight thereof.

12 . The modular stack of claim 10 , wherein the side plate extends less than a length of the first side, wherein the side plate extends upward less than a height of the basket of which it is a part, wherein the side plate defines at least two openings, wherein the at least two openings are positioned above the bottom, wherein the one or more cross-members extend from the at least two openings, and wherein the one or more cross-members are hollow to receive a connection for a lifting mechanism.

13 . The modular stack of claim 10 , wherein the second baskets comprises:

a base frame that is substantially rectangular;

one or more cross-members extending from a first side of the base frame to a second side of the base frame;

a center support extending from a first end of the base frame to a second end of the base frame, and wherein the one or more cross-members are perpendicular to the center support.
