## Background
BACKGROUND
The present disclosure relates to an article-storage unit, and particularly to a multi-compartment article-storage unit. More particularly, the present disclosure relates to a compactable article-storage unit for storing personal items.
SUMMARY
An article-storage unit in accordance with the present disclosure includes a tray formed to include an interior storage region. The tray includes a floor and a side wall coupled to a perimeter edge of the floor.
In illustrative embodiments, the article-storage unit further includes a detachable tray organizer that can, at the option of the consumer, be coupled to the tray to partition the interior storage region. The tray is made of a pliable material and, once the consumer detaches the tray organizer from the tray, the consumer can fold the tray to assume a smaller size that can be stored in a small space until it is needed later. A manufacturer can also fold the tray to form a compact unit that can be packaged in a small box at retail.
In illustrative embodiments, the tray organizer includes a partition wall, a front lid pivotably coupled to a top edge of the partition wall, and a rear divider panel coupled to a rear side of the partition wall. A consumer can mount the tray organizer in the interior storage region of the tray in the field to establish a front chamber and to establish a separate rear chamber divided by the rear divider panel into two side-by-side compartments and to orient the front lid so it can be moved to cover the front chamber. The article-storage unit also includes a rear lid that is movable to close the two compartments in the rear chamber and one or more front divider panels for dividing the front chamber into two or more compartments.
In illustrative embodiments, the floor of the tray carries a floor anchor that can be operated by a consumer to anchor the tray to an underlayment such as a pad or a carpet in the trunk of a vehicle. The floor anchor includes a piercing member that can be rotated about a vertical axis manually by a co to pierce an outer surface of the underlayment to retain the tray temporarily in a stationary position on the underlayment. The consumer can retract the piercing member from the underlayment by rotating the piercing member about the vertical axis in an opposite direction so that the tray can be folded easily to assume a stowable compact shape when the article-storage unit is not in use.
Additional features of the present disclosure will become apparent to those skilled in the art upon consideration of illustrative embodiments exemplifying the best mode of carrying out the disclosure as presently perceived.
