The present disclosure provides a storage box, including a bottom, a first side wall, a second side wall, a third side wall and a fourth side wall. The first side wall, the second side wall, the third side wall and the fourth side wall sequentially surround the bottom. The first side wall is parallel to the third side wall, the second side wall is parallel to the fourth side wall, the first side wall is perpendicular to the second side wall, a first notch is disposed on the first side wall, a second notch is disposed on the second side wall, a width of the first notch is larger than or equal to a thickness of the second side wall, a width of the second notch is larger than or equal to a thickness of the first side wall.

The invention is a wheeled folding tray cart and method. The wheeled folding tray cart comprises a collapsible wheeled framework pivotally supporting a set of split shelves, each split shelf comprises a pair of half shelves. The wheeled folding tray cart moves between an open operating position wherein the set of split shelves are held in spaced-apart, stacked, horizontal orientation within the collapsible wheeled framework and a closed storage position wherein the collapsible wheeled framework is collapsed in manner to move each half shelf pair into an accordion-like, inverted “V”-shaped or accordion like configuration. An extension coiled spring attached to the collapsible wheeled framework assists in the movement of the wheeled folding tray cart between open operating position and the closed storage position. A sheath encloses at least a portion of the spring to provide resistance to the spring's movement to limit potential operator exposure to pinch injuries.

A cart, such as a kitchen cart, has a bottom shelf supported by leg members. The leg members further support a central shelf or basket at a user-desired position along the legs, and a top support. The top support can retain a top work surface thereto. On at least one side of the cart, arms can pivot outward, adjacent the top work surface, to support one or more work surface extension members. Typically, there may be one work surface extension member on each side of the cart, providing the user with additional workspace and providing the option of removal without interfering with the functionality of the cart.

A wheeled shipping/transport cart includes a cart frame that supports a plurality of wheels. The cart frame supports a plurality of stackable trays. The trays include a tray frame with opposed end members, a plurality of longitudinal support members disposed between the opposed end members, and a plurality of upright members nesting with upright members of an adjacent tray. A support structure is disposed between the opposed end members to form an arc corresponding to a curved surface of an article to be supported by the support structure. A pin is received through each of the upright members of the plurality of stackable trays to retain the stackable trays in a stacked configuration.

A collapsible cart may include a collapsible frame, a foldable shelf, and an interior support column. The collapsible frame includes a first frame portion and a second frame portion. The frame is configured to move between an open configuration and a collapsed configuration by relative translation between the first frame portion and the second frame portion. The foldable shelf extends between the first frame portion and the second frame portion. The foldable shelf is configured to fold to allow the frame to move from the open configuration to the collapsed configuration. The column transversely extends through a column slot defined by the foldable shelf. The cart further includes at least one column brace slidably coupling the frame to the column. The cart further includes at least one shelf brace slidably coupling the foldable shelf to the column.

The wheeled folding tray cart comprises a collapsible wheeled framework pivotally supporting a set of split shelves, each split shelf comprises a pair of half shelves. The wheeled folding tray cart moves between an open operating position wherein the set of split shelves are held in spaced-apart, stacked, horizontal orientation within the collapsible wheeled framework and a closed storage position wherein the collapsible wheeled framework is collapsed in manner to move each half shelf pair into an accordion-like, inverted “V”-shaped or accordion like configuration. An extension coiled spring attached to the collapsible wheeled framework assists in the movement of the wheeled folding tray cart between open operating position and the closed storage position. A sheath encloses at least a portion of the spring to provide resistance to the spring's movement to limit potential operator exposure to pinch injuries.

A novel logistics system is disclosed involving a roll container (100) with a base (110) and two elongated supports (120) that are supported by the base (110). The supports each have a plurality of individual slots (122) provided in a spaced apart configuration along the supports (120) for receiving a tab (133, 134) of a respective plurality of shelves (130) in a spaced apart configuration. The roll container may further include a folding mechanism between the base and the supports for turning the supports between an operational state and a folded state. In the operational state of the roll container the supports extend transversally in respect to the base. In the folded state of the roll container the supports extend parallel to the base.

A tote cart, having: a base; a plurality of wheels positioned underneath the base; a pair of upwardly extending supports mounted to the base; and a plurality of cantilevered shelves, wherein each cantilevered shelf is configured to be mounted onto the pair of upwardly extending supports. The cantilevered shelves are removable and re-positionable to different heights on the upwardly extending supports and have a perimeter member spanning around the front and sides of the shelf, and a moveable shelf that can be moved from a first position parallel to the perimeter member to second position at a dropped down angle to the perimeter member.

A charging and storage cart can be configured to support and charge a plurality of electronic devices. The charging and storage cart can include a frame, a panel, a tray, a support bracket, and an extension. The panel can be secured to the frame and can include a body and plurality of apertures extending through the body. The support bracket can be coupled to the tray and can be configured to engage the panel to support the tray. The extension can be connected to the support bracket can be insertable into any aperture of the plurality of apertures to connect the tray to the body of the panel in any location as desired.
