COLLAPSIBLE CONTAINER WITH MULTIPLE RETRACTABLE WALLS
In some embodiments, a collapsible container includes a base and a plurality of walls including a first wall and an adjacent second wall. The first wall and the second wall each include a U-shaped frame hingeably secured to the base and at least one section pivotably secured to the respective frame to selectively restrict and facilitate access to an interior of the container. A frame latch selectively secures the frame of the first wall to the frame of the second wall.
The present invention relates generally to containers and more particularly to a crate that is particularly useful for transporting grocery items to a store.
Currently, grocery items may be shipped to stores in metal crates. The crates must be unloaded onto shelves for the customers to select and purchase. This requires labor for handling the grocery items in the store.
SUMMARYMultiple embodiments of collapsible containers are disclosed herein. The containers can be delivered, stacked in the store and the items therein can be merchandized straight out of the containers. The retractable walls can be retracted to improve visibility and accessibility to the products inside the container. The walls can be moved to the retracted position even while another loaded container is stacked on the container.
If all of the walls of the container are retractable, then there would be no need to orient the containers in a particular direction when stacked in the store. Most likely, depending upon where the containers are placed, only the one or two walls of each container in the stack that face the customer would need to be collapsed to provide ready access to the items inside; however, it would be possible to retract three or even four of the walls of all of the containers in the stack.
In the examples shown, all four walls of the collapsible container have retractable panels or sections. Some of the retractable sections have multiple pivot points and some have a single pivot point. Latches are selectively released to permit the retraction of each wall. Latches are also provided to permit the walls to all be collapsed onto the base of the container when the container is empty. In the example embodiments shown, each has multiple retractable walls, although there are some inventive features that could be practiced independently with only a single retractable wall. Unless otherwise specifically recited in the claim, it is within the scope of this invention that fewer than all of the walls and optionally only one wall is retractable.
In some embodiments, a collapsible container includes a base and a plurality of walls including a first wall and an adjacent second wall. The first wall and the second wall each include a U-shaped frame hingeably secured to the base and at least one section pivotably secured to the respective frame to selectively restrict and facilitate access to an interior of the container. A frame latch selectively secures the frame of the first wall to the frame of the second wall. The frames lock together to provide sufficient support to multiple similar loaded container stacked thereon.
Some embodiments of a collapsible container include a base having opposed side edges meeting opposed end edges at corners of the base. An end projection projects upwardly along the side edges adjacent each corner. A pair of opposed side walls are hingeably secured at the side edges of the base. A pair of opposed end walls are hingeably secured to the end projections.
A collapsible container according to some embodiments includes a base and a pair of opposed first walls pivotable between an upright position and a collapsed position. A pair of opposed second walls are pivotable between an upright position and a collapsed position. At least one of the second walls includes a U-shaped frame and a section pivotably secured to the frame. The section is pivotable between a closed position and a retracted position. A latch selectively secures the section to the frame in the closed position. The frame includes a lower portion parallel to the base and opposite vertical portions projecting upward from opposite ends of the lower portion. The frame further includes a pair of upper portions projecting toward one another from upper ends of the vertical portions.
A latch securing one of the side walls to one of the end walls may be movable vertically to selectively release the one of the side walls from the one of the end walls.
A collapsible container 10 according to a first embodiment is shown in
Each side wall includes a plurality of retractable sections 18, here shown in the closed or upright position. Retractable sections 18 are pivotably connected to a U-shaped frame 20 and/or to one another.
Similarly, the end walls 16 each include a plurality of retractable sections 22 pivotably connected to one another and/or to a U-shaped frame 24. The frame 24 includes a lower portion hingeably connected to the end flange 17 and two upstanding portions at each end of the lower portion. A pair of latches 25 selectively secure the sections 22 to the frame 24. In this embodiment, the upper retractable section 22 is connected to arms extending downward to lower ends pivotably secured to the frame 24. The lower retractable section 22 is pivotably connected at an upper end thereof to the arms, while the lower end of the lower retractable section 22 hangs down freely or snap-fit connects to the arms.
On the side walls 14 a pair of latches 28 selectively secure the retractable sections 18 to the frame 20. Another pair of latches 26 selectively secure the frame 20 of the side wall 14 to the frame 24 of the end wall 16. Releasing these latches 26 permit the side walls 14 to be collapsed onto the base 12. The end walls 16 would subsequently be collapsed onto the side walls 14. In particular, in this embodiment, the upper retractable section 18 is connected to arms extending downward to lower ends pivotably secured to the frame 20, while the lower retractable section 18 is pivotably secured at its upper end to the arms. The lower end of the lower retractable section 18 may hang down freely or latch to the arms.
