CROSS-REFERENCE TO RELATED APPLICATIONS  
       [0001]     This application claims the benefit of U.S. Provisional Application Ser. No. 60/659,235 filed on Mar. 7, 2005, incorporated herein by reference. 
     
    
     FIELD OF THE INVENTION  
       [0002]     This invention is drawn to the field of structures and laminations, and more particularly, to novel modular clean room structures and laminations for the life sciences and health-care and other industries.  
       BACKGROUND OF THE INVENTION  
       [0003]     The primary function of the Life Science Clean Room Wall Manufacturer is to create “aseptic” conditions throughout—systems that, by design, are easy to sterilize and will prevent microbial contamination. This is the FDA requirement known as “cGMP,” which stands for current Good Manufacturing Practices. The FDA informally looks to U.S. Pat. No. 797 as the latest mandate for facility protocol in the life sciences. According to 797, all pharmacies, health care institutions and facilities where compounded sterile preparations are prepared stored and dispensed, are to adhere to even higher standards of aseptic protocol. For such products as “biologics, diagnostics, drugs, nutrients or radiopharmaceuticals, and such preparations as baths and soaks for live organs and tissues, implants, inhalations, injections, irrigations, metered sprays, ophthalmic and optic procedures,” raising the standards of cGMP is the FDA&#39;s charge.  
         [0004]     To adhere to these requirements, wall manufacturers must construct and finish interior surfaces that are homogenous, monolithic, and free of seams, joints and open crevices that harbor bacteria. Typically, walls heretofore have employed mitered corner posts, surface applied corner moldings, hand-formed plastic radius or on-site thermo-formed corners.  
         [0005]     Most often, end users find themselves spending exorbitant amounts of money on excessive labor and materials costs to custom build these conditions. And, once achieved, end users still find themselves with a continuous problem—the inability to deconstruct or demount the wall system in a way that will prohibit contamination and reconstruction.  
         [0006]     In most cases, if not all, significant portions of wall systems are destroyed during retro-fit procedures, whether it&#39;s demounting or expanding.  
         [0007]     There is thus the need provide modular clean room structures and eliminations for the life sciences health care and other industries or applications that overcomes these and other disadvantages.  
       BRIEF SUMMARY OF THE INVENTION  
       [0008]     Accordingly, it is one object of the present invention to provide modular clean room structures and laminations for the life sciences and health care and other industries or applications.  
         [0009]     It is another object of the present invention to provide modular clean room structures for the life sciences industries that are load bearing and non-load bearing.  
         [0010]     It is another object of the present invention to provide demountable (non-progressive) or installed (progressive) modular clean room structures.  
         [0011]     It is a further object of the present invention to provide novel clean room structures of the types described that provide smooth, seamless, readily cleanable structural interfaces when walls meet wall-to-wall, wall-to-floor and wall-to-ceiling that reduce if not eliminate the potential for microbial contamination.

The modular structures cooperate to provide load and non-load bearing self-standing walls in any configuration depending on the number and kind of modular structures utilized. The modular laminations of the present invention enable to clad over self-standing walls that are either newly built or already existing to provide aseptic, easily wipeable surfaces free of seams, joints and crevices were microbes could build-up. The modular structural and lamination components, that are usable together, provide the flexibility and versatility needed to satisfy the requirements of a wide variety of application situations in the life sciences, health care and other industries and other aseptic environments.

     DETAILED DESCRIPTION  
       [0044]     The modular clean room structures for biological sciences and other applications of the present invention enable to provide clean rooms that are modular in design, so that they may be installed, taken down and re-installed as the needs of the situations change, and also enable to provide clean room walls that are easily wipeable to prevent microbe buildup and/or contamination at the corners, floors and ceilings. The modular clean room structures for biological sciences applications of the present invention may be able to support loads or may be non-load bearing. The modules are fastenable to load bearing or non-load bearing structures using seperable fasteners. There are seven principal modular clean room structures in accord with the present invention, namely, a base track, a ceiling track, inside and outside corners, and connector wall sections of preferably two lengths, a larger and a smaller wall connector, as well as a two-piece batten wall connector. The sixth principal component is the preferably laminated, partition wall members themselves. Joints for the base and ceiling tracks are the seventh. Another component is a window frame module. A further component of the modular clean room structures in accord with the present invention is an end cap panel. The base track and the ceiling track have coved surfaces that are easily wipeable. The inside and/or the outside corner subassemblies have coved surfaces that meet with the coved surfaces of the base track and of the ceiling track to provide easily wipeable floor-to-wall, wall-to-ceiling and wall-to-wall surfaces at the interfaces therebetween. The inside and outside corner subassemblies are preferably vacuum-formed and enable to clad-over the corners of rooms and the corners of T-walls. The corner and T-wall subassemblies provide chases in which load bearing members may be used to provide load bearing struts and/or utility wire runs. The wall subassemblies are lightweight laminated structures having a core and skins and the base track and ceiling track subassemblies are preferably extruded. The modules are typically fabricated of standard-sized components and enable to provide rooms having easily wipeable surfaces of any given size in dependence on the number and arrangement of components utilized.  
         [0045]     With reference to  FIG. 1 , the principal structures that may be fabricated in accord with the present invention and joined to provide inside and outside load bearing and non-load bearing clean room environments for the biological or other industries will now be described. As shown in  FIG. 1 , generally designated at  100  is a schematic plan view illustrating a corner subassembly generally designated  300 , a T-wall subassembly generally designated  500  and a wall subassembly generally designated  700 . Preferably laminated, partition walls  150  to be described are joined at corners by the corner subassembly  300  that includes insides corner subassembly  350  and outside corner subassembly  400 . The preferably laminated, partition walls  150  may also be joined in the manner of a T-wall  500  by inside corners  350  and T-wall member  550  to be described and may be joined by wall sections  700  using wall members  750  to be described.  
         [0046]     Referring now to  FIGS. 2 and 3 , generally designated at  50  is the base track in accord with the present invention. The base track  50  is used to provide a seamless transition between the floor and the wall panels to be described that are easily wipeable and minimize microbe contamination. The floor track  50  is of standard length, such as 12 feet, and extruded of polyvinyl chloride or other material capable of repeated wiping and able to withstand multiple doses of strong cleaning agents. The base track  50  includes concave sidewalls  52 , a top tongue  54 , and bottom radius edges  56  that accept caulking. A cross brace  58  provides strength to the base track  50  and divides its hollow interior into upper and lower cavities which may be employed as races for utility wiring or the like. As will be readily appreciated, the concave surfaces  52  provide coves that are easily wipeable. The tongue  54  mates with a groove of a joint member to be described to provide a demountable interface between the base track and the laminated wall panels.  
         [0047]     Referring now to  FIGS. 4 and 5 , generally designated at  100  is a joining member in accord with the present invention. The joining member  100  is used to attach the base track to the laminated walls at their bottom and to attach the ceiling track to be described to the laminated walls at their top in a manner to be described. The attachment between the laminated walls and base and ceiling tracks may be non-progressive or progressive. The joining number  100  is of standard length, such as 12 ft., and extruded of polyvinyl chloride or other material. The joining member  100  includes a U-shaped member  102 , flanges generally designated  104  and grooves generally designated  106  provided along the flange&#39;s outer faces. As appears more fully below, the U-shaped member  102  provides a groove that accepts the tongue  54  of the base track  50  ( FIGS. 1 and 2 ) and defines a tongue for the ceiling track in a manner to be described. When laying the base track for non-progressive installations, the groove provided by the U-shaped wall  102  accepts the tongue of the base track and prevents delamination of the laminated sidewalls, not shown. The U-shaped member  102  absorbs wear and tear and provides for repeated re-use of the laminated walls.  
         [0048]     Referring now to  FIG. 6 , generally designated at  150  is a preferably laminated, partition wall panel in accord with the present invention. The laminated panels  150  are preferably of standard length, such as 4 foot by 8 foot panels that are 2 in. thick. Any suitable core material, such as aluminum honeycomb, and foam, and any suitable skins  154 ,  156 , such as of plastic, polyvinyl chloride, or other veneers, may be employed. The laminated panels  150  are provided with a longitudinal cutout  158  along their bottom edges that is adapted to receive the joint  100  ( FIGS. 4, 5 ). As described above, the joint placed into the bottom groove receives the tongue and prevents the laminated panel  150  from delaminating with repeated use.  
         [0049]      FIG. 7  is an end isometric view illustrating the base track joint member  100  set in the laminated wall panel. The inset  100  preferably is adhesively bonded into the cut-out provided at the bottom of the laminated panel  150 . Partition walls of another structure or fabrication technique may of course be employed.  
         [0050]     Generally designated  200  in  FIG. 8A  is the ceiling track in accord with the present invention. The ceiling track  200  includes an enlarged top member  202  whose sidewalls taper downwardly to provide concave wipeable surfaces  204  at the laminated wall to ceiling interfaces. The concave surfaces  204 , or coves, are easily wipeable. A strut  206  provides strength. The strut  206  divides the cavity of the ceiling track  200  to provide utility or other raceways. As for the bottom track, the ceiling track  200  is extruded to standard length, preferably 12 ft., and is fabricated of polyvinyl chloride. The ceiling track  200  is separably attached to the laminated panels  150  by means of the joint  100  as shown in  FIG. 8B . The joint  100  in the case of the ceiling track serves as a tongue that mounts in the open mouth generally designated  208  of the ceiling track  206  for progressive installations. The bead line, not show, again accepts caulking to provide a seamless ceiling track to laminated wall interface.  
         [0051]     Generally designated at  350  in  FIG. 9  is the vacuum-formed inside corner subassembly of the present invention. The inside corner subassembly  350  preferably is vacuum formed of a thermoformable material such as PVC to include an upstanding portion  352  having a C-shape defining an inside corner that terminates in a base  354  that is contoured to match the contours of the concave walls of the base track and the contour of the upstanding C-shaped wall  352 . Ridges along the sides of the upstanding member  352  designated generally at  356  are provided for seamless interfacing with laterally adjacent panels at the corner subassembly  300  and/or T-wall subassembly  500  ( FIG. 1 ). The ridges provide joggles in the vacuum-formed monolithic component which helps to rigidify it. The vacuum-formed inside corner subassembly  350  by means of the curvature of the portion  352  and the compound curvature of the portion  354  provides an aseptic condition. The inside corner subassembly may be removably joined by means of separable fasteners, not shown, to the laterally adjacent walls, or heat-welded thereto for progressive installations.  
         [0052]     Generally designated at  400  in  FIG. 10  is the vacuum-formed outside corner subassembly of the present invention. The outside corner subassembly  400  preferably is vacuum formed of a thermoformable material such as PVC to include an upstanding portion  402  having a C-shape defining an outside corner that terminates in a base  404  that is contoured to match the contours of the concave walls of the ceiling track and the contour of the upstanding C-shaped wall  402 . Ridges along the sides of the upstanding member  402  designated generally at  406  are provided for seamless interfacing with laterally adjacent panels at the corner subassembly  300  ( FIG. 1 ). The vacuum-formed outside corner subassembly  400  by means of the curvature of the portion  402  and the compound curvature of the portion  404  provides an aseptic condition. The outside corner subassembly may be removably joined by means of separable fasteners, not shown, to the laterally adjacent walls, or heat-welded thereto for progressive installations.  
         [0053]     Top end terminations of compound curvature, not shown, may be provided with the inside and outside corner subassemblies.  
         [0054]      FIG. 11  is a sectional view through an outside corner showing the inside and outside corner subassemblies  350 ,  400  seamlessly joining corner walls provided by laminated panels  150 . Post base  600  and Unistrut  602  are shown in the chase between the inner and outer subassemblies  350 ,  400 . The post base  600  preferably includes a bottom and a preferably 6 inch post of stainless steel or other metal or material upstanding therefrom. The Unistrut  602  is slidably received over the post of the base  600  and self-aligns thereupon. Any suitable means such as bolt holes may be provided for anchoring the post base  600  to the floor. In this manner, corner, T-wall and wall subassemblies of the present invention are able to support load-bearing Unistruts or other load bearing members in the chases provided thereby, in which utility and other such cables or ducts and the like can be run.  
         [0055]      FIG. 12  is an isometric view showing an inside corner  350  either at a T-wall or outside corner and illustrating the manner of joining of the base track  50  to the laminated panels  150  via the joining member  100 .  
         [0056]      FIG. 13  is an exposed isometric view illustrating the inside corner members  350  and a wall connector  550  to be described. Inside the chase provided thereby, Unistruts  602  placed at the three corners of the chase are mounted on post bases  600 . The inside corner subassemblies  350  seamlessly join with the laminated walls  150  forming the T-wall juncture. Again, they may be heat-welded to the skins of the laminated panels  150  or separable fasteners, not shown, may be provided.  
         [0057]     Generally designated at  550  in  FIG. 14  is the larger panel connector subassembly of the present invention. The member  550  is preferably of standard dimensions and is vacuum-formed of a thermoformable PVC plastic or other material with an upstanding portion  552  that terminates in a foot portion  554  that is contoured to match the contour of the base track. A contoured head portion of compound curvature, not shown, may be provided. The edges of the panel  550  are provided with ridges generally designated  556  that allow seamless joining with adjacent laminated panels and therewith provide rigidity imparting joggles.

It includes a concave foot  952  that conforms to the curvature of the base track subassembly and a non-progressive top end generally designated  954 . A concave top end, not shown, for progressive installations may be employed. In addition to protecting the otherwise exposed end of the laminated partition wall, the surface thereof is easily wipeable to prevent microbe built-up. Rolled radius trim edge  956  provides for ease of wipeability.  
         [0062]      FIG. 20  depicts a two-piece batten subassembly used to connect laterally adjacent partition walls, the female batten is designated generally at  1000  in the  FIG. 20A  and the male batten is designated generally at  1030  in the  FIG. 20B . The female batten  1000  includes a mushroom-shaped head having an easily wipeable convex surface  1010  that serves to span over and thus join the laterally adjacent partition walls and a serrated female member generally designated  1020  that is received in the interstice between laterally adjacent partition walls. The male batten  1030  similarly includes a mushroom-shaped head having an easily wipeable concave surface  1010  likewise serving to span over and join laterally adjacent partition walls and a serrated male member generally designated  1040  that is received in and captured by the serrated female member  1020  of the female batten  1000 . The female and male battens  1000 ,  1030  are as tall as the partition walls; the female member  1020  of the female batten  1000  is as deep as the preferably laminated, partition walls are thick. Preferably, the two-piece batten subassembly is vacuum-formed of PVC and may be trimmed to length.  
         [0063]     Generally designated at  1050  in  FIG. 21  is another embodiment of the vacuum-formed outside corner subassembly of the modular clean room structures of the present invention, which is also usable as a lamination component of the modular clean room laminations of the present invention. The outside corner subassembly  1050  preferably is vacuum formed of a thermoformable material such as PVC to include an upstanding portion  1052  having a V-shape defining an outside corner that terminates in a base  1054  that is contoured to match the contours of the concave walls of the base track. The V-shape makes the subassembly useable as a lamination at the outside corner of walls, not shown, to be clad-over as well as a constituent part of corner subassemblies made up of structural modules. Ridges along the sides of the upstanding member  1052  designated generally at  1056  are provided for seamless interfacing with laterally adjacent panels or other wall structures or lamination components of the present invention. The vacuum-formed outside corner subassembly  1050  by means of the curvature of the portion  1054  and the edge of the portion  1052  provides an aseptic condition. The outside corner subassembly may be removably joined by means of separable fasteners, not shown, to the laterally adjacent walls, or heat-welded thereto for progressive installations; likewise, separable fasteners, or heat-welds, may be used to join it to laterally adjacent lamination components to be described. A horizontal flange  1058  is provided to help rigidify the component. The subassembly  1050  preferably is sized to a standard size wall and is trimable as desired.  
         [0064]     Top end termination of curvature matching the curvature of the ceiling track, not shown, may be provided.  
         [0065]     The clean room laminations for biological sciences and other applications of the present invention are modular in design, so that they may be installed as cladding to walls (either newly constructed or already in place according to the needs of the application&#39;s situation), to provide aseptic surfaces that are easily wipeable to prevent microbe buildup and/or contamination at walls and inside and outside corners both of full and wainscot sizes. The modular clean room laminations for biological sciences and other applications of the present invention are usable alone as cladding and are interoperable with the modular clean room structures described hereinabove, which makes the laminations and structures very versatile and renders them capable of accommodating the needs of a very wide range of application&#39;s situations. There are three principal laminations in accord with the present invention, namely, a wall liner lamination, and inside and outside corner laminations, which preferably are fashioned in two sizes, either as a standard wall or wainscot wall. These laminations each include coved, easily wipeable surfaces that conform to the coved surfaces of the modular clean room structures in accord with the present invention. The lamination modules are preferably vacuum-formed of thermoplastic material, such as PVC, in standard sized, trimable monolithic, homogenous components that enable to provide easily wipeable surfaces when clad to walls or used together with the modular clean room structures in accord with the present invention.  
         [0066]     Referring now to  FIG. 22 , generally designated at  1100  is the monolithic full-size wall liner panel lamination in accord with the present invention preferably fabricated by vacuum forming of PVC material and that may be trimmed to fit. The wall liner panel lamination  1100  includes a generally planar upstanding wall-covering portion  1102  that terminates in a coved foot or base  1104  whose curvature matches that of the other laminations or structures herein described so that it is usable therewith while being easily wipeable. The base  1104  preferably includes a generally-horizontal inwardly directed flange  1106  that helps to impart rigidity to the liner panel  1100 . The edges are radiused as shown at  1108  to provide a butt joint that is easy to heat-weld or caulk.  
         [0067]     Generally designated at  1150  in  FIG. 23  is a vacuum-formed inside corner wainscot lamination of the present invention. The inside corner lamination  1150  preferably is vacuum formed of a thermoformable material such as rigid PVC to include an upstanding portion  1152  having a C-shape defining an inside corner that terminates in the base  1154  having a concave cove that is contoured to match the contours of the concave walls of the wall liner panel lamination and of the base track subassembly described hereinabove and the contour of the upstanding C-shape wall  1152 . Ridges along the sides of the outstanding member  1152  designated generally at  1156  provide seamless interfacing with laterally adjacent wall liner panel laminations (or other structures) in accord with the present invention. A triangular-shape top wall  1158  is provided to close off the wedge that otherwise would be defined at the inside corner of the wall to be clad. The vacuum-formed inside corner subassembly  1150  by means of the curvature of the portion  1152  and the compound curvature of the portion  1154  provides an aseptic condition. A flange  1160  helps provide rigidity. The inside corner subassembly may be removably joined by means of separable fasteners, not shown, to laterally adjacent laminations (or other structures) or heat-welded or otherwise bonded thereto.  
         [0068]     Generally designated at  1200  in  FIG. 24  is the vacuum-formed outside corner wainscot lamination of the present invention. The outside corner wainscot lamination  1200  preferably is vacuum formed of a thermoformable material such as rigid PVC to include an upstanding portion  1202  having a rounded bull nose outside corner edge that terminates in a base  1204  having a concave cove that is contoured to match the contours of the concave walls of the wall liner panel lamination and of the base track subassembly described hereinabove and the contour of the rounded bull nose outside corner edge of the upstanding wall  1202 . Ridges along the sides of the outstanding member  1202  designated generally at  1206  provide seamless interfacing with laterally adjacent wall liner panel laminations (or other structures) in accord with the present invention. The joggle of the ridges imparts rigidity. An inwardly extending generally horizontal flange  1208  along the base  1204  helps to provide the outside corner wainscot panel lamination  1200  with rigidity. The vacuum-formed outside corner subassembly  1200  by means of the curvature of the portion  1202  and the compound curvature of the portion  1204  provides an aseptic condition. The outside corner subassembly may be removably joined by means of separable fasteners, not shown, to laterally adjacent laminations (or other structures) or heat-welded or otherwise bonded thereto.  
         [0069]     Referring now to  FIG. 25 , generally designated at  1250  is the liner wainscot panel lamination in accord with the present invention. Preferably, it is fabricated by vacuum forming, preferably 20 in. or 40 in. wainscot sizes corresponding to that of the inside and outside wainscot corner laminations described above. Of course, any suitable wainscot size for the liner wainscot panel and inside and outside wainscot corner panel laminations may be employed. The wall liner wainscot panel lamination  1250  includes a generally planar upstanding wall-covering portion  1252  that terminates in a coved foot or base  1254  whose curvature matches that of the other laminations or structures herein described so that it is usable therewith while being easily wipeable. The top edge is radiused as shown at  1256  to provide for ease of wipeability.
