Abstract

A container includes a plurality of walls extending upwardly from a base. The walls are movable between an upright position and a collapsed position on the base. Supports are pivotably mounted to the end walls. Ends of the supports are received in arcuate channels in the side walls. A tab or other projection downward from the base is aligned with arcuate channel to engage the spring-loaded fingers on a dolly.

Description

  • This application claims priority to U.S. Provisional Application Ser. No. 61/237,668 filed Aug. 27, 2009.
  • BACKGROUND OF THE INVENTION
  • Collapsible crates are well known. Four walls each connected via a hinge to a base are selectively movable about the hinge between a use position, in which the wall is generally perpendicular to the base, and a collapsed position onto the base. Various latch mechanisms have been provided to connect adjacent walls at the corner to selectively lock the crate in the use position.
  • Some collapsible crates also include retractable supports so that another, non-collapsible, nestable container can be supported thereon. One such collapsible crate includes end walls each having a support that is partially supported on the adjacent walls when in the support position. The nestable containers can be supported on the supports when the supports are in the support position. Ends of the supports are received in arcuate channels in the adjacent walls to permit the end walls to be collapsed.
  • The collapsible crates may be stacked on a dolly having spring-loaded locking fingers designed to interlock with recesses on some containers stacked thereon. On some dollies, the spring-loaded locking fingers are aligned with the collapsible crate in a location where a recess cannot be provided. In particular, the spring-loaded locking fingers are aligned with the arcuate channels in the adjacent walls.
  • SUMMARY OF THE INVENTION
  • The present invention provides a container having a end walls and side walls extending upwardly from a base. The walls are movable between an upright position and a collapsed position on the base. Supports are pivotably mounted to the end walls. Ends of the supports are received in arcuate channels in the side walls. A tab or other projection downward from the base is aligned with arcuate channel to engage the spring-loaded fingers on a dolly.
  • The container may further include at least one rib on an exterior of the side wall. The rib may include a recess formed therein to accommodate the downward projection of an identical container stacked thereon when the container is in a collapsed position with the plurality of walls collapsed on the base
  • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a perspective view of a container according to one embodiment of the present invention in an assembled upright position.
  • FIG. 2 shows the container of FIG. 1 in a collapsed position.
  • FIG. 3 is an interior perspective view of a quarter of the container of FIG. 1.
  • FIG. 4 is an interior view of one of the end walls.
  • FIG. 5 is an exterior view of the quarter of the container of FIG. 3.
  • FIG. 6 is an enlarged view of a portion of FIG. 5.
  • FIG. 7 is a section view of the container of FIG. 2 in a collapsed position with the base of an identical container stacked thereon.
  • FIG. 8 is an enlarged view of a portion of FIG. 7.
  • FIG. 9 is a section view through a portion of the container of FIG. 1 adjacent an alignment finger on a dolly.
  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • A collapsible container 10 according to one embodiment of the present invention is shown in FIG. 1. The collapsible container 10 includes a base 12, collapsible side walls 14 (or “long walls”) and collapsible end walls 18 (or “short walls”). The side walls 14 are pivotably connected to upstanding side members 16, which are integrally molded with the base 12 and extend upwardly along the side edges of the base 12. Each end wall 18 includes a support member 20 pivotably and slidably connected thereto by arms 24.
  • As shown in FIG. 2, the end walls 18 and side wall 14 are collapsible onto the base 12 for convenient shipping and storage when empty.
  • A quarter view of the collapsible container 10 is shown in FIG. 3. The collapsible container 10 would be symmetric about the section lines. Each of the support members 20 includes a support portion 21 extending between opposite ends 22, which protrude outwardly relative to the arms 24. Each side wall 14 includes an arcuate channel 30 adjacent each end wall 18. The end 22 of the support member 20 is received in the associated channel 30. The channel 30 extends from an upper portion of the side wall 14 to a vertical channel 34 through the upstanding portion 16.
  • In FIG. 3, the support member 20 is shown in the support position. In FIG. 4, the support member 20 is shown pivoted to a retracted position.
  • FIG. 5 is an exterior view of the container 10 showing the bottom of the base 12. As shown, the base 12 includes a plurality of feet 38 (or a drag rail) protruding downwardly. Aligned at least partially with the channel 34 through the upstanding portion 16 is a downward projection, such as an alignment rib or tab 40 projecting downwardly from the base 12. The alignment rib 40 is arranged to abut a spring-biased finger or button (which may be spring biased and retractable) on a dolly or other support surface, to prevent the container 10 from sliding relative to the dolly or support surface.
  • As shown in FIG. 6, the side wall 14 includes some recesses to accommodate the alignment rib 40. For example, the exterior surface of the side wall 14 may include vertical ribs 42, 44 which overlap an exterior surface of the arcuate channel 30. An opening 46 is formed through the surface of the arcuate channel 30 and a recess 48 is formed through one of the vertical ribs 44.
  • FIGS. 7 and 8 show the collapsed container 10 with the base 12′ of an identical container 10′ stacked thereon (walls of the upper container 10′ removed for clarity). As shown, when stacking collapsed containers 10, 10′, the alignment rib 40′ of the upper container 10 is received in the opening 46 through the surface of the arcuate channel 30 and the recess 48 through the rib 44. This permits the containers 10, 10′ to stack stably when in the collapsed position.
  • FIG. 9 is a section view through a portion of the container 10 on a dolly 60. The dolly 60 includes a plurality of alignment fingers 62 (one shown) each biased upwardly by a spring 64 to prevent the container 10 from sliding off the dolly 60. The base 12 of the container 10 partially compresses the finger 62 into the deck of the dolly 10 and the rib 40 abuts an inner surface of the finger 62 to help keep the container 10 in position on the dolly 10. The container 10 may include such a rib 40 aligned with each of the vertical channels 34 in the upstanding members 16, and the ribs 40 may each engage a different spring-loaded finger 62 in the manner shown in FIG. 9.
  • In accordance with the provisions of the patent statutes and jurisprudence, exemplary configurations described above are considered to represent a preferred embodiment of the invention. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope.
