Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
152 words
A method for constructing a multiple component latticed framework container comprising the steps of; a. positioning a plurality of structural elements in an arrangement that establishes a desired unitary latticed framework that defines open interstices, sAid framework comprising extensive regions in which certain surface portions of some of said structural elements are closely adjacent to certain surface portions of other of said structural elements; b. securing said structural elements together at only locations spaced substantial distances apart in said extensive regions so as to provide said framework as a relatively weakly integrated structure; c. encapsulating said entire framework with an adherent plastic material so as to cover said structural elements and fill said extensive regions between said adjacent surface portions while maintaining said open interstices; and d. curing said adhering plastic to form a bond between all said adjacent surface portions and thereby substantially enhance the structural integrity of said latticed framework.
Claim 2
Independent Claim
152 words
A method for constructing a multiple component latticed framework container comprising the steps of; a. positioning a plurality of structural elements in an arrangement that establishes a desired unitary latticed framework that defines open interstices, sAid framework comprising extensive regions in which certain surface portions of some of said structural elements are closely adjacent to certain surface portions of other of said structural elements; b. securing said structural elements together at only locations spaced substantial distances apart in said extensive regions so as to provide said framework as a relatively weakly integrated structure; c. encapsulating said entire framework with an adherent plastic material so as to cover said structural elements and fill said extensive regions between said adjacent surface portions while maintaining said open interstices; and d. curing said adhering plastic to form a bond between all said adjacent surface portions and thereby substantially enhance the structural integrity of said latticed framework.
Claim 3
Dependent Claim
50 words
A method according to claim 1 wherein said structural elements comprise elongated rectilinear members, said positioning step comprises arranging pairs of said elongated rectilinear members in directly adjacent substantially parallel relationship, and said extensive regions comprise the elongated area between adjacent surfaces of said pairs of substantially parallel elongated members.
Claim 4
Dependent Claim
27 words
A method according to claim 2 wherein said securing step comprises fixing annular securing elements about said parallel elongated rectilinear members at longitudinally spaced apart locations thereon.
Claim 5
Dependent Claim
26 words
A method according to claim 2 wherein said securing step comprises producing discrete bonds between said parallel elongated rectilinear members at longitudinally spaced apart positions thereon.
Claim 6
Dependent Claim
23 words
A method according to claim 4 wherein said elongated rectilinear members are metallic and said longitudinally distributed bonds are formed by welding steps.
Claim 7
Dependent Claim
68 words
A method according to claim 2 wherein said structural elements comprise a plurality of elongated rod members and web material means, and said positioning and securing steps comprise; arranging and securing together said elongated members to form an open sided housing, covering open sides of said housing with said web material means, and securing said rod members to directly adjacent parallel oriented strands of said web material means.
Claim 8
Dependent Claim
28 words
A method according to claim 6 wherein said securing step comprises producing discrete bonds between said directly adjacent rod members web strands at longitudinally spaced apart positions thereon.
Claim 9
Dependent Claim
24 words
A method according to claim 7 wherein said rod members and web are metallic and said longitudinally distributed bonds are formed by welding steps.
Claim 10
Dependent Claim
63 words
A method according to claim 2 wherein said structural elements comprise a plurality of web material sections, said positioning steps comprises arranging said web material sections so as to form a desired enclosure framework, and said certain surface portions comprise strands of some of said web material sections which are adjacent and substantially parallel to strands of other of said web material sections.
Claim 11
Dependent Claim
26 words
A method according to claim 6 wherein said securing step comprises fixing annular securing elements about said directly adjacent strands at longitudinally spaced apart locations thereon.
Claim 12
Dependent Claim
23 words
A method according to claim 1 wherein said encapsulating step comprises submerging said unitary framework in a body of said adherent plastic material.
Claim 13
Dependent Claim
18 words
A method according to claim 11 wherein said body comprises a liquid bath of said adherent plastic material.
Claim 14
Dependent Claim
29 words
A method according to claim 12 wherein said body comprises said plastic material in fluid form, and including the step of heating said framework prior to said submerging step.
Claim 15
Dependent Claim
55 words
A method according to claim 1 wherein said positioning step comprises arranging a plurality of latticed panels so as to form walls of a cage having a removal opening with individual strands of each of said latticed panels being positioned directly adjacent individual strands in other of said latticed panels to provide said extensive regions.
Claim 16
Dependent Claim
18 words
A method according to claim 14 including the step of attaching a removable cover over said removal opening.
Claim 17
Dependent Claim
17 words
A method according to claim 15 wherein said panels are arranged in the form of a box.
Claim 18
Dependent Claim
32 words
A method according to claim 14 wherein said arranging step comprises forming in one of said walls an entrance opening larger than any of said interstices and smaller than said removal opening.
Claim 19
Dependent Claim
29 words
A method according to claim 17 wherein said forming step comprises forming said one wall in the shape of a truncated cone having an apex defining said entrance opening.
