摘要:
A storage container for storage of one or more items in a storage and retrieval system containing a track system including first and second sets of horizontal parallel tracks forming a grid pattern having a plurality of grid spaces and stacks of storage containers located beneath the track system, wherein each stack occupies a single grid space. The storage container includes a metallic container body including a base portion formed as a single unitary body and having a container bottom wall and upwardly standing base sidewall and end wall parts to define a tray, and a separate upper portion having upper sidewall and end wall parts upwardly extending from and connected to respective base sidewall and end wall parts to form a box-like structure with an open end for receiving items within the box-like structure.

A collapsible serving tray that is stiff and flat when open and reduced in size and compact when folded. The tray is designed to be folded up into a compact size that is about one-quarter of the fully deployed size of the tray. One embodiment of the tray includes a perimeter edge that is ninety degrees to the flat serving surface when the tray is fully deployed.

A storage basket is provided, including a bottom meshwork and a side meshwork. The side meshwork formed with at least one mesh element extends transversely and upwardly from and surrounds the bottom meshwork. Each mesh element is an expanded metal mesh and includes a top frame portion disposed at a top end and a meshed portion located between the bottom meshwork and the top frame portion, and the expanded metal mesh is formed by using die stamping to expandedly mesh a solid metal plate. The top frame portion and the meshed portion of each mesh element are formed integrally.

A two-dimensional sheet material is provided that is suitable for bending along a bend line to form a three-dimensional object. The sheet material is provided with a plurality of displacements in a thickness direction of the sheet material on one side of the bend line. A portion of the displacements shear adjacent the bend line and define an edge and an opposed face. The edge and opposed face configured to produce edge-to-face engagement of the sheet material during bending. Alternatively, sheet material is provided with a plurality of displacements in a thickness direction of the sheet material on one or both sides of the bend line, and with a plurality of corresponding and cooperating protrusions to improve structural integrity and/or to improve electromagnetic and radio frequency shielding. The sheet material may also be provided with a self-latching structure. A method of preparing and using these sheet materials is also described.

摘要:
The present invention relates to a combination storage and carrying device for holding and transporting a plurality of items, such as stacked firewood, wherein the device includes a support assembly and a pair of handles pivotally attached thereto. The support assembly includes a base member and a plurality of attached side wall members for retaining items positioned on the base member. Each of the handles pivots between fully extended and fully retracted positions as needed, and the handles include end portions which elevate the support assembly above a support surface.
摘要:
A bakery pan comprising a series of cups drawn from rectangular sheet metal plates. The lateral edges of each plate are bent downwardly at right angles to the plane of the plate to provide welding and reinforcing edge flanges, which flanges are vertically spot welded to flanges of adjacent plates to form a pan from a matrix or array of plates. The resulting pan or array of cups are reinforced in the plane of the plate (horizontally) by the abutting vertical flanges of the plates, only small portions of which are consumed by the spot welds.
