Abstract
Abstract A shipping pad is provided which has three dimensional shock resistant characteristics. The component parts of the shipping pad may be fabricated from a single sheet of plastic foam material, thus facilitating storage of the unit prior to assembly. After the component parts are removed from the sheet of foam material, they may be assembled into a shipping pad configuration with interlocking cross bars. No adhesive or other fastening means foreign to the foam material need be used.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
205 words
A shock resistant shipping pad for packing an article in a transport container comprising: a frame having parallel top and bottom members integrally joined to perpendicularly disposed first and second end members to define an aperture complementing an outer surface of the article; said frame top member having a plurality of transverse grooves disposed at spaced points along a top surface of said frame top member; said frame bottom member having a plurality of transverse grooves disposed at spaced points along a bottom surface of said frame bottom member opposite said transverse grooves of said frame top member; and a plurality of cross members for providing lateral shock resistance to the article, each cross member having upper and lower ends and transversing said aperture defined by said frame members, such that said cross member upper ends of said plurality of cross members engage and interlock with said frame top member transverse apertures and said lower ends of said plurality of cross members engage and interlock with a corresponding frame bottom member transverse aperture to permit the outer surface of the article to contact said frame members and said plurality of cross members to provide three dimensional shock resistance to the article within the transport container.
Claim 2
Dependent Claim
205 words
A shock resistant shipping pad for packing an article in a transport container comprising: a frame having parallel top and bottom members integrally joined to perpendicularly disposed first and second end members to define an aperture complementing an outer surface of the article; said frame top member having a plurality of transverse grooves disposed at spaced points along a top surface of said frame top member; said frame bottom member having a plurality of transverse grooves disposed at spaced points along a bottom surface of said frame bottom member opposite said transverse grooves of said frame top member; and a plurality of cross members for providing lateral shock resistance to the article, each cross member having upper and lower ends and transversing said aperture defined by said frame members, such that said cross member upper ends of said plurality of cross members engage and interlock with said frame top member transverse apertures and said lower ends of said plurality of cross members engage and interlock with a corresponding frame bottom member transverse aperture to permit the outer surface of the article to contact said frame members and said plurality of cross members to provide three dimensional shock resistance to the article within the transport container.
Claim 3
Dependent Claim
27 words
The combination of claim 1 wherein said plurality of cross members overlap said frame top and bottom members to abut upper and lower surfaces of the article.
Claim 4
Dependent Claim
17 words
The combination of claim 2 wherein each of said plurality of cross members are C-shaped in structure.
