Abstract
Abstract A unitary, composite, multi-layer work area is provided which can support a plurality of work pieces thereon. The work area includes a structure which comprises a pair of outer protective covering layers and inner rigid core means, respectively. Preferably, a pair of networks are disposed between the outer covering layers and the inner core means. Either or both of the networks can be replaced with a perforated, crush-proof structure. The layers of the structure are uniformly joined one to the other substantially along the entirety of their respective adjacent surfaces to form a laminate-like support structure. Fastening means passing within the subject work area are employed to maintain the work pieces in the requisite position. The structure can be supported in a fixed or in a plurality of adjustable positions with respect to the horizontal axis.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
150 words
A unitary, composite, multi-layer structure for supporting work pieces of differing sizes, shapes, and weights, and any auxiliary equipment required, said work piece support comprising rigid inner permeable core means which acts as a spacer means, and provides substantial rigidity and increases the overall impact-resistant nature of said structure, and outer protective covering layers for encapsulating the inner structural components of said structure, said outer protective covering layers including a plurality of expandable openings which are capable of engaging fastening means of varying sizes which pass therethrough for interlockingly supporting a plurality of work pieces thereon without damaging the structural integrity of said outer layers, the respective outer layers and core means being uniformly joined together one to the other substantially along the entirety of their respective adjacent surfaces to form a laminate-like structure capable of permitting a plurality of fastening means to penetrate said structure for interlocking engagement therewith.
Claim 2
Dependent Claim
150 words
A unitary, composite, multi-layer structure for supporting work pieces of differing sizes, shapes, and weights, and any auxiliary equipment required, said work piece support comprising rigid inner permeable core means which acts as a spacer means, and provides substantial rigidity and increases the overall impact-resistant nature of said structure, and outer protective covering layers for encapsulating the inner structural components of said structure, said outer protective covering layers including a plurality of expandable openings which are capable of engaging fastening means of varying sizes which pass therethrough for interlockingly supporting a plurality of work pieces thereon without damaging the structural integrity of said outer layers, the respective outer layers and core means being uniformly joined together one to the other substantially along the entirety of their respective adjacent surfaces to form a laminate-like structure capable of permitting a plurality of fastening means to penetrate said structure for interlocking engagement therewith.
Claim 3
Dependent Claim
25 words
The structure of claim 1, wherein the core means is substantially solid throughout its entirety for applying further torque to the fastening means passing therethrough.
Claim 4
Dependent Claim
16 words
The structure of claim 1, wherein the core means is formed of a high density material.
Claim 5
Dependent Claim
70 words
The structure of claim 1, wherein yieldable networks, containing a plurality of openings and spaced apart one with respect to the other, positioned in substantially parallel planes at a predetermined distance, are located between said outer protective layers and inner core means, respectively, said networks interacting to provide a plurality of retaining means for maintaining in an interlocking position fastening means which pass through said openings engaging said respective networks.
Claim 6
Dependent Claim
29 words
The structure of claim 4, wherein said networks are positioned so that the openings in each of said networks are in a non-aligned relationship one with respect to another.
Claim 7
Dependent Claim
49 words
The structure of claim 5, wherein one of said networks comprises a rigid, impact-resistant, substantially non-yieldable layer containing a plurality of permanent openings through which said fastening means may pass to provide, in combination with said yieldable network means, a maximum torque to be exerted on said fastening means.
Claim 8
Dependent Claim
54 words
The structure of claim 6, wherein each of said networks comprises rigid, impact-resistant, substantially non-yieldable layers, to provide a substantially crush-resistant structure, the respective openings in each of said networks being in substantially horizontal alignment such that when fastening means pass therethrough they are in relatively vertical disposition one with respect to the other.
Claim 9
Dependent Claim
17 words
The structure of claim 3, wherein said high density core means is fabricated of rigid, high-density polyurethane.
Claim 10
Dependent Claim
26 words

Claim 11
Dependent Claim
26 words
The structure of claim 1, which further includes support means for maintaining said structure in a fixed angular disposition with respect to the normal horizontal axis.
Claim 12
Dependent Claim
26 words
The structure of claim 1, which further includes support means for maintaining said structure in a fixed horizontal disposition with respect to the normal horizontal axis.
Claim 13
Dependent Claim
26 words

Claim 14
Dependent Claim
28 words
The structure of claim 1, which further includes adjustable support means for maintaining said structure in a plurality of angular dispositions with respect to the normal horizontal axis.
Claim 15
Dependent Claim
28 words
The structure of claim 1, which further includes adjustable support means for maintaining said structure in a plurality of vertical dispositions with respect to the normal horizontal axis.
Claim 16
Dependent Claim
28 words
The structure of claim 1, which further includes adjustable support means for maintaining said structure in a plurality of horizontal dispositions with respect to the normal horizontal axis.
Claim 17
Dependent Claim
27 words
The structure of claim 1, which further includes adjustable multi-positional support means for maintaining said structure in a plurality of predetermined vertical and/or horizontal and/or angular positions.
Claim 18
Dependent Claim
