This invention relates to structure claddings. Particular embodiments of the invention provide structure claddings and methods and apparatus for installing and repairing structure claddings.
It is known to clad structures with structure claddings. Structure claddings typically include a plurality of longitudinally and transversely extending panels, each having one end configured to attach to the structure and another end configured to engage an adjacent panel.
Well-known problems with prior art structure claddings of this nature include the difficulties of installation and repair.

Break X indicates that structure 40 may be of any suitable length and any suitable number of panels 30 may extend along surface portion 44B of structure 40. Break Y indicates that panels 30 may be of any suitable length.

Any suitable number of panels 30 (e.g. panels 30-1, 30-2, . . . 30-n-1, 30-n) may be installed adjacent to one another in this manner.

Installation of panel 30-n is difficult. If panel 30-n is cut too long, it is not possible to deform panel 30-n enough to insert its male end 34 into the female end 36 of panel 30-n-1 while simultaneously inserting its cut end 39 into space 19. If panel 30-n is cut too short, it is prone to falling out after being installed. The material of panel 30-n may be relatively stiff and it may require significant force to deform panel 30-n into its installed position, particularly when the transverse dimension of panel 30-n is relatively small. The deformation of panel 30-n may damage panel 30-n. Further, the restorative forces associated with deforming panel 30-n can cause damage to corner piece 10-2.

For structure claddings with large numbers of panels, it may be very time consuming to sequentially remove all of the panels necessary to reach a damaged panel, and to re-install all of the removed panels.
There is a general desire for improved structure claddings and for improved methods for installing and/or repairing structure claddings.
The foregoing examples of the prior art and limitations related thereto are intended to be illustrative and not exclusive. Other limitations of the prior art will be apparent to those skilled in the art upon a reading of the specification and a study of the drawings.
The following embodiments and aspects thereof are described and illustrated in conjunction with apparatus and methods which are meant to be exemplary and illustrate, not limiting in scope. In various embodiments, one or more of the above-described problems have been reduced or eliminated, while other embodiments are directed to other improvements.
One aspect of the invention provides a cladding kit for a structure cladding, the structure cladding comprising a first panel that extends away from a structure location along a first surface portion of the structure and a second panel that extends away from the structure location along a second surface portion of the structure, the first and second surface portions on opposed sides of the structure location. The structure location may be a corner. The cladding kit comprises: a base piece couplable to the structure at the structure location, the base piece comprising a base connector; and a trim piece comprising first and second wings and a trim connector shaped to make a connection with the base connector to thereby couple the trim piece to the base piece. The first wing is shaped to contact, and be deformed by, the first panel when the connection is made and to exert restorative force against the first panel after the connection is made. The second wing is shaped to contact, and be deformed by, the second panel when the connection is made and to exert restorative force against the second panel after the connection is made.
Another aspect of the invention provides a cladding apparatus for a structure cladding, the structure cladding comprising a first panel that extends away from a structure location along a first surface portion of the structure and a second panel that extends away from the structure location along a second surface portion of the structure, the first and second surface portions on opposed sides of the structure location. The structure location may be a corner. The cladding apparatus comprises: a base piece coupled to the structure at the structure location, the base piece comprising a base connector, and a trim piece comprising first and second wings and a trim connector coupled to the base connector to form a connection therebetween and to thereby couple the trim piece to the base piece. The first wing is shaped to contact, and be deformed by, the first panel when the connection is made between the trim connector and the base connector and to exert restorative force against the first panel after the connection is made The second wing is shaped to contact, and be deformed by, the second panel when the connection is made between the trim connector and the base connector and to exert restorative force against the second panel after the connection is made.
Another aspect of the invention provides a method for lining a corner of a structure with a structure cladding, the structure cladding comprising a first panel that extends away from the corner of the structure along a first surface portion of the structure and a second panel that extends away from the corner of the structure along a second surface portion of the structure, the first and second surface portions on opposed sides of the corner. The method comprises: coupling a base piece to the structure at the corner of the structure; providing a trim piece comprising first and second wings; and coupling the trim piece to the base piece to make a connection therebetween. Coupling the trim piece to the base piece to make the connection comprises: contacting the first wing to the first panel and exerting force which causes the contact between the first wing and the first panel to deform the first wing, and contacting the second wing to the second panel and exerting force which causes the contact between the second wing and the second panel to deform the second wing. After the connection is made between the trim piece and the base piece, the first wing exerts restorative force against the first panel and the second wing exerts restorative force against the second panel.
Another aspect of the invention provides a method for replacing at least a portion of a particular panel of a structure cladding, the structure cladding comprising a plurality of edge-adjacent panels which line a surface of a structure. The method comprises: removing a first portion of the particular panel from the surface of the structure to leave a remaining portion of the particular panel attached to the surface of the structure; mounting a base piece to the structure at a base location adjacent to the remaining portion of the particular panel; locating a replacement panel along the surface of the structure at a replacement panel location, the replacement panel location on a side of the base piece opposite that of the remaining portion of the particular panel; and coupling a trim piece comprising a first wing to the base piece to form a connection therebetween. Coupling the trim piece to the base piece comprises contacting the first wing to the replacement panel and exerting force which causes the contact between the first wing and the replacement panel to deform the first wing. After the connection is made between the trim piece and the base piece, the first wing exerts restorative force against the replacement panel.
In addition to the exemplary aspects and embodiments described above, further aspects and embodiments will become apparent by reference to following detailed description and study of the drawings.
Exemplary embodiments are illustrated in referenced figures of the drawings. It is intended that the embodiments and figures disclosed herein are to be considered illustrative rather than restrictive.
In drawings which depict non-limiting embodiments of the invention:
Throughout the following description specific details are set forth in order to provide a more thorough understanding to persons skilled in the art. However, well known elements may not have been shown or described in detail to avoid unnecessarily obscuring the disclosure. Accordingly, the description and drawings are to be regarded in an illustrative, rather than a restrictive, sense.
Base piece 110 comprises a structural central component 111 supporting a mounting tab 112 and an extending tab 113 which extend from central component 111. Extending tab 113 comprises deformation component 115 at an end distal from central component 111. Deformation component 115 may be shaped such that when a force is applied against deformation component 115 in direction A, deformation component 115 may contract in direction A and may exert restorative force opposed to direction A.
Deformation component 115 may comprise the “zig zag” shape shown in
The tip 115-3 of deformation component 115 may be bevelled to extend away from surface portion 144B of structure 140 to be cladded (see
Base piece 110 of the illustrated embodiment comprises a nub 119 with a beveled edge 119-1. Nub 119 may provide a physical indicator of the correct placement of a panel 130C-1 (see
Inside corner base piece 110 comprises a connector 114 for connecting to a complementary connector of an inside corner trim piece 120, as explained below. Connector 114 of the illustrated embodiment comprises a plurality (e.g. two) of arms 117. In the illustrated embodiment, each of arms 117 comprises a hooked portion 118. Hooked portions 118 comprise hook protrusions 118-1 that define hook concavities 118-2. Hook concavities 118-2 open toward mounting tab 112 and extending tab 113, respectively (i.e. toward surface portions 144B and 144C, respectively, of structure 140 to be cladded (see
The illustrated portion of structure cladding 2000, as seen in
Breaks X indicate that structure 140 may be of any suitable length and that any suitable number of panels 130 may extend along the surface portions 144B and 144C of structure 140. Break Y indicates that panels 130 may be of any suitable length.
Panels 130B-1, 130B-2, . . . 130B-n-1, 130B-n extend in longitudinal directions (i.e. into and out of the page in the views in
Structure 140 may comprise any suitable structure. Structure 140 may comprise drywall, gyprock, studs, concrete, furring strips, plywood, masonry, stucco, other wall layers, etc. Structure 140 may comprise the floor, ceiling, roof, exterior walls, interior walls, etc. of a structure. Structure 140 may comprise all of or a portion of a building, barn, silo, food storage container, car wash, factory, etc. Structure 140 may be rectilinear or curved. Where structure 140 is curved, panels 130 may be curved to match the curvature of structure 140. Additionally or alternatively, panels 130 may be deformable such that they can be deformed to match the curvature of structure 140.
Where surface 144 structure 140 has gaps (e.g. where surface 144 of structure 140 comprises transversely spaced apart studs or the like), one or more backing components may be attached between the studs to fill some portions of some gaps (e.g. the spaces between the studs) so that panels 130 or other components of a structure cladding (e.g. corner base pieces, repair strip base pieces) may be attached to the backing via fasteners 150.
Structure cladding 2000 of the illustrated embodiment is mounted to structure 140 by a plurality of fasteners 150. Fasteners 150 may comprise any suitable fasteners, including screws, nails, bolts, staples, etc. In some embodiments, structure cladding 2000 is mounted to structure 140 by other means, such as suitable adhesives and/or the like.
Each panel 130 comprises a male end 134 and a female end 136. Female end 136 comprises a mounting tab 138.

Nub 119 extends out of mounting tab 112. Nub 119 may provide a physical (e.g. tactile) indicator of the correct placement of panel 130B-1 relative to base piece 110-1. The male end 134 of panel 130B-1 may be slid across mounting tab 112 until it contacts nub 119, indicating that panel 130B-1 is correctly placed relative to base piece 110-1. Nub 119 has a bevelled edge 119-1. Bevelled edge 119-1 may be angled away from surface portion 144B of structure 140 as it extends toward corner 146A. This shape may tend to urge male end 134 of panel 130B-1 to deform slightly away from surface portion 144B of structure 140 when panel 130B-1 is forced or otherwise moves toward central component 111 of base piece 110-1. This interaction between panel 110B-1 and bevelled edge 119-1 of nub 119 may occur, for example, because of thermal expansion.
In
Panel 130B-n-1 is attached to structure 140 by fasteners 150 which extend through its mounting tab 138 in a manner similar to panel 130B-1.
In
When panels 130B-1, 130B-2, . . . 130B-n-1, 130B-n experience thermal expansion (or contraction), deformation component 115 may deform so that it continues to engage cut end 139 of panel 130B-n and continues to exert a restorative force against cut end 139 of panel 130B-n.
In the illustrated embodiment, panels 130 are double walled panels with support braces 135 extending between wall 137-1 and wall 137-2. In

As trim piece 120 is forced in direction B, bevelled surfaces 128-3 of hooked portions 128 contact bevelled surfaces 118-3 of hooked portions 118. The relative angles of bevelled surfaces 128-3 and beveled surfaces 118-3 (as discussed above) are shaped such that forcing trim piece 120 in direction B causes arms 127 to deform away from each other and/or arms 117 to deform toward each other. As trim piece 120 is forced further in direction B, arms 127 pass arms 117, so that arms 117 extend between arms 127. For this reason, connector 124 may be referred to as a “female connector” and connector 114 may be referred to as a “male connector”. In other embodiments, trim piece 120 comprises a male connector and base piece 110 comprises a female connector.
When trim piece 120 is forced sufficiently far in direction B, hook protrusions 128-1 of trim piece 120 pass hook protrusions 118-1 of base piece 110-2. From this configuration, moving trim piece 120 in a direction opposed to direction B causes hook protrusions 128-1 to extend into hook concavities 118-2 and hook protrusions 118-1 to extend into hook concavities 128-2. Movement of trim piece 120 in the direction opposed to direction B may be caused by restorative forces associated with deformation of connectors 114, 124 and/or wings 122. The engagement of hook protrusions 128-1 and hook protrusions 118-1 with hook concavities 118-2 and hook concavities 128-2, respectively, locks trim piece 120 to base piece 110-2 and prevents trim piece 120 from becoming unconnected from base piece 110-2.
In its unconnected state, wings 122 of trim piece 120 form an angle Θ, as shown in
Base piece 110 may be used on a corner of greater than or less than 90 degrees. In some embodiments, mounting tab 112 and extending tab 113 can be deformed toward each other (i.e. so that they form an angle of less than 90 degrees) or away from one another (i.e. so that they form an angle of more than 90 degrees) to form any angle between 80 degrees and 110 degrees. In some embodiments, both mounting tab 112 and extending tab 113 may be attached by fasteners 150 to structure 140; this may be particularly desirable where base piece 110 is used on a corner of greater than 90 degrees. In some embodiments, the angle formed between mounting tab 112 and extending tab 113 (in their undeformed positions) may be any angle between 30 and 150 degrees to facilitate use with a correspondingly wide variety of corner shapes.
Base piece 160 comprises a central component 161 supporting mounting tabs 162 extending from central component 161. Mounting tabs 162 may comprise nubs 168. Nubs 168 may extend away from mounting tabs 162 toward surface portions 144D and 144E, respectively, of the structure 140 to be cladded (see
Mounting tabs 162 of the illustrated embodiment comprise deformation components 163 at ends distal from central component 161. Deformation components 163 may be shaped such that when forces are applied against deformation components 163 in directions C and D, respectively, deformation components 163 may contract in directions C and D, respectively, and exert restorative forces opposed to directions C and D, respectively.
Deformation components 163 of the illustrated embodiment comprise the “hockey stick” shapes shown in
Arms 163-2 of deformation components 163 may be bevelled to extend away from surface portions 144D and 144E, respectively, of the structure 140 to be cladded (see
Outside corner base piece 160 comprises a connector 164 for connecting to a complementary connector of an inside corner trim piece 170, as explained below. Connector 164 of the illustrated embodiment comprises a plurality (e.g. two) of arms 167 extending away from central portion 161. Arms 167 comprise outer surfaces 167-1, inner surfaces 167-2, and ends 167-3.
In
Outside corner base piece 160 is attached to a structure 140 by fasteners 150 which extend through mounting tabs 162. For every fastener 150 shown in
As trim piece 170 is forced in direction E, curved surfaces 178-3 of hooked portions 178 contact outer surfaces 167-1 of arms 167. The relative orientations of curved surfaces 178-3 and outer surfaces 167-1 (as discussed above) are such that forcing trim piece 170 in direction E causes arms 177 to deform away from each other and/or arms 167 to deform toward each other. As trim piece 170 is pushed further in direction E, arms 177 pass arms 167, so that arms 167 extend between arms 177. For this reason, connector 174 may be referred to as a “female connector” and connector 164 may be referred to as a “male connector”. In other embodiments trim piece 170 comprises a male connector and base piece 160 comprises a female connector.
When trim piece 170 is forced sufficiently far in direction E, hook protrusions 178-1 of arms 177 pass ends 167-3 of arms 167. From this configuration, moving trim piece 170 in a direction opposed to direction E causes ends 167-3 to extend into hook concavities 178-2. Movement of trim piece 170 in the direction opposed to direction E may be caused by restorative forces associated with deformation of connectors 164, 174 and/or wings 172. The engagement of ends 167-2 with hook concavities 178-2 locks trim piece 170 to base piece 160 and prevents trim piece 170 from becoming unconnected from base piece 160.
In its unconnected state, wings 172 of trim piece 170 form an angle α, as seen in
Base piece 160 may be used on a corner of greater than or less than 270 degrees. In some embodiments, mounting tabs 162 can be deformed toward each other (i.e. so that they form an angle of more than 270 degrees) or away from one another (i.e. so that they form an angle of less than 270 degrees) to form any angle between 260 degrees and 280 degrees. In some embodiments, mounting tabs 162 may deform about the “fulcrums” provided by numbs 168. In some embodiments, the angle formed between mounting tabs 162 (in their undeformed positions) may be any angle between 210 and 330 degrees.
In the embodiment illustrated in
In some embodiments, deformation components 163 may contact panels 130D and 130E in a similar way to the contact between deformation component 115 and panel 130X, as described above and as illustrated in
Base piece 180 comprises a central component 181 supporting mounting tabs 182 which extend from central component 181. Mounting tabs 182 comprise deformation components 183 at ends distal from central component 181. Deformation components 183 may be shaped such that when forces are applied against deformation components 183 in directions F and G, respectively, deformation components 183 contract in directions F and G, respectively and exert restorative force opposed to directions F and G, respectively.
Deformation components 183 may function similarly to deformation components 163, as described above.
Obtuse corner base piece 180 comprises a connector 184 for connecting to a complementary connector of an obtuse corner trim piece 190, as explained below. Connector 184 of the illustrated embodiment may comprise a stem 185 extending from central component 181. Stem 185 comprises a guiding arrow 186 located at the end of stem 185 distal from central component 181. Guiding arrow 186 is shown in greater detail in
As shown in
Stem 185 comprises barbs 188. Barbs 188 comprise barb protrusions 188-1 that define barb concavities 188-2. Barb concavities 188-2 open toward central component 181 (i.e. toward surface portions 144F and 144G, respectively, of structure 140 to be cladded (see
Base piece 180 may comprise arms 187 that define receptacles 187-1.
Base piece 180 may comprise a nub 189 extending away from central component 181. Nub 189 may provide a physical (e.g. tactile) indicator of the correct placement of base piece 180 relative to a corner 146F of a structure 140 to be cladded (see
In
In the illustrated embodiment, nub 189 does not touch corner 146F. In some embodiments, however, nub 189 may touch corner 146F. Contact between nub 189 and corner 146F may provide a physical (e.g. tactile) indicator of the correct placement of base piece 180 relative to structure 140.
Obtuse corner base piece 180 is attached to a structure 140 by fasteners 150 which extend through mounting tabs 182. For every fastener 150 shown in
Male ends 134 of panels 130F and 130G are inserted into receptacles 187-1 of base piece 180. In some embodiments of the invention, cut off ends of panels 130 may be attached to surface portions 144F and 144G and may contact deformation components 183 in a similar way to the contact between deformation component 115 and panel 130X, as described above and as illustrated in
As trim piece 190 is forced in direction H, bevelled surfaces 198-3 of arms 197 contact bevelled surfaces 186-3 of guiding arrow 186. The relative angles of bevelled surfaces 198-3 and bevelled surfaces 186-3 (as discussed above) are such that forcing trim piece 190 in direction H causes arms 197 to deform away from each other. As trim piece 190 is pushed further in direction H, arms 197 pass guiding arrow 186, so that guiding arrow 186 enters receptacle 199. For this reason, connector 194 may be referred to as a “female connector” and connector 184 may be referred to as a “male connector”. In other embodiments trim piece 190 comprises a male connector and base piece 180 comprises a female connector.
When trim piece 190 is forced sufficiently far in direction H, hook protrusions 198-1 of trim piece 190 pass arrow protrusions 186-1 guiding arrow 186. From this configuration, moving trim piece 190 in a direction opposed to direction H causes arrow protrusions 186-1 to extend into hook concavities 198-2 and hook protrusions 198-1 to extend into arrow concavities 186-2. Movement of trim piece 190 in the direction opposed to direction H may be caused by gravity. The engagement of arrow protrusions 186-1 and hook protrusions 198-1 with hook concavities 198-2 and arrow concavities 186-2, respectively, holds trim piece 190 in place. This configuration between trim piece 190 and base piece 180 may be referred to as a “preliminary connection”. The retention forces associated with this preliminary connection may be greater than the force of gravity on trim piece 190, such that a preliminary connection could be used to hold trim piece 190 in place (relative to base piece 180) if direction H was vertically upward. For example, in some embodiments, base piece 180 may be attached to a ceiling, and the preliminary connection may facilitate easy installation of trim piece 190 to base piece 180. In some embodiments, it may be possible to form the preliminary connection without using tools (e.g. using only bare hands and not a mallet).
As trim piece 190 is pushed still further in direction H (e.g. by mallet blows), bevelled surfaces 198-3 of arms 197 contact bevelled surfaces 188-3 of barbs 188. The relative angles of bevelled surfaces 198-3 and bevelled surfaces 188-3 (as discussed above) are such that forcing trim piece 190 in direction H causes arms 197 to deform away from each other. When trim piece 190 is forced sufficiently far in direction H, hook protrusions 198-1 of trim piece 190 pass barb protrusions 188-1 of barbs 188. From this configuration, moving trim piece 190 in a direction opposed to direction H causes barb protrusions 188-1 to extend into hook concavities 198-2 and hook protrusions 198-1 to extend into barb concavities 188-2. Movement of trim piece 190 in the direction opposed to direction H may be caused (in part) by restorative forces associated with deformation of connectors 194, 184 and/or wings 192. The engagement of barb protrusions 188-1 and hook protrusions 198-1 with hook concavities 198-2 and barb concavities 188-2, respectively, locks trim piece 190 to base piece 180 and prevents trim piece 190 from becoming unconnected from base piece 180.
Wings 192 of trim piece 190 may have structures and functions that are similar to the structures and functions of wings 172 of trim piece 170, as described above and as illustrated in
Base piece 180 may be used on a corner of greater than or less than 115 degrees. In some embodiments, mounting tabs 182 can be deformed toward each other (i.e. so that they form an angle of less than 115 degrees) or away from one another (i.e. so that they form an angle of greater than 115 degrees) to form any angle between 105 degrees and 125 degrees. In some embodiments, the angle formed between mounting tabs 182 (in their undeformed positions) may be any angle between 5 and 175 degrees.
One embodiment of the invention comprises methods and apparatus for repairing an existing structure cladding.
Base piece 200 comprises a central component 201. Base piece 200 also comprises a connector 204 for connecting to a complementary connector of a repair strip trim piece 210, as explained below. Connector 204 of the illustrated embodiment comprises a plurality (e.g. two) of arms 207. In the illustrated embodiment, each of arms 207 comprises a hooked portion 208. Hooked portions 208 comprise hook protrusions 208-1 that define hook concavities 208-2. Hook concavities 208-2 open toward central component 201 (i.e. toward the surface portion 144H of the cladded structure 140 (see
In some embodiments repair strip 200 may have deformation components (not shown) on one or both sides of central component 201. These deformation components may be similar to deformation components 115 or 163, as described above.

Using the method illustrated in
To repair a panel (e.g. panel 130) adjacent to a corner base piece (e.g. inside corner base piece 110, outside corner base piece 160, obtuse corner base piece 180), the corner trim piece (e.g. inside corner trim piece 120, outside corner trim piece 170, obtuse corner trim piece 190) connected to the corner base piece may be removed. In some embodiments the corner trim piece may be removed from the corner base piece by grasping the corner trim piece (e.g. by its wings) and pulling it. In some embodiments, the corner trim piece may be removed from the corner base piece by sliding the corner trim piece up or down relative to the corner base piece. In some embodiments, the corner trim piece may be removed by being cut (e.g. down its center in the longitudinal dimension). After the corner trim piece is removed and a replacement panel is moved into position adjacent to the corner base piece, a corner trim piece (e.g. the original corner trim piece or a new corner trim piece) may be connected to the corner base piece so that a wing of the corner trim piece secures an end (e.g. a cut end, a male end, a female end) of the replacement panel.
When a corner trim piece or a repair strip trim piece is damaged, it may be removed (e.g. using one of the methods described above) and a new trim piece may be installed (e.g. using one of the methods described above).
Panels may be configured to have any combination of male ends, female ends, and cut ends along their four edges. Corner base pieces and repair strip base pieces may be configured to receive any combination of male ends, female ends, and cut ends on their two opposing sides.
The structure claddings in the illustrated embodiments are not necessarily to scale. In some embodiments, some panels may be larger than others.
Panels 130 are double-walled, but in other embodiments there may be panels with greater or fewer numbers of walls. In some embodiments, panels 130 contain insulating material.
The structure cladding and repair pieces of this invention may be made of any suitable material, including plastic, metal, etc. They may be manufactured by any suitable method, including extrusion, coextrusion, injection molding, casting, machining, etc. In some embodiments, different components of the same part may be made of different materials (e.g. a part may have both plastic and rubber components; such a part may be manufactured by coextrusion).
In some embodiments the structure cladding and repair pieces may be made of material that is suitable for food storage applications. In some embodiments, the interfaces between adjacent panels and the interfaces between panels and trim pieces are tight enough to be suitable for food storage applications. In some applications these interfaces are watertight.
The structure cladding and repair pieces may be attached to a structure by any suitable means, including fasteners (e.g. screws, nails, bolts, etc.), adhesives, magnets, Velcro® etc.
The connections between the base pieces and the trim pieces described herein may be referred to as “snap together” connections. In some embodiments, other designs of “snap together” connections may be used. For example: connections with greater or fewer than two arms and two hooked portions, “ball and socket” connections, “tongue and groove” connections, etc. In some embodiments, other types of connections between base pieces and trim pieces may be used. For example: adhesive connections, magnetic connections, Velcro® connections, etc.
Some embodiments of the invention comprise structure claddings with no “sharp corners” (i.e. structure claddings with a minimum radii of curvature (e.g. 0.1 cm, 1 cm, 5 cm, and/or the like)). Structure claddings with no sharp corners may be easier to clean, and may be suitable for food storage applications and/or may comply with food storage regulations.
Although the operations of the methods herein are shown and described in a particular order, the order of the operations of each method may be altered so that certain operations may be performed in an inverse order or so that certain operation may be performed, at least in part, concurrently with other operations.
Where a component is referred to above, unless otherwise indicated, reference to that component (including a reference to a “means”) should be interpreted as including as equivalents of that component any component which performs the function of the described component (i.e. that is functionally equivalent), including components which are not structurally equivalent to the disclosed structure which performs the function in the illustrated exemplary embodiments of the invention.
Those skilled in the art will appreciate that directional conventions such as “vertical”, “transverse”, “horizontal”, “upward”, “downward”, “forward”, “backward”, “inward”, “outward”, “vertical”, “transverse” and the like, used in this description and any accompanying claims (where present) depend on the specific orientation of the apparatus described. Accordingly, these directional terms are not strictly defined and, unless the context dictates otherwise, should not be interpreted narrowly.
Unless the context clearly requires otherwise, throughout the description and any accompanying claims (where present), the words “comprise,” “comprising,” and the like are to be construed in an inclusive sense, that is, in the sense of “including, but not limited to.” As used herein, the terms “connected,” “coupled,” or any variant thereof, means any connection or coupling, either direct or indirect, between two or more elements; the coupling or connection between the elements can be physical, logical, or a combination thereof. Additionally, the words “herein,” “above,” “below,” and words of similar import, shall refer to this document as a whole and not to any particular portions. Where the context permits, words using the singular or plural number may also include the plural or singular number respectively. The word “or,” in reference to a list of two or more items, covers all of the following interpretations of the word: any of the items in the list, all of the items in the list, and any combination of the items in the list.
While a number of exemplary aspects and embodiments have been discussed above, those of skill in the art will recognize certain modifications, permutations, additions and sub-combinations thereof. As will be apparent to those skilled in the art in the light of the foregoing disclosure, many alterations and modifications are possible in the practice of this invention and the appended claims should be given the broadest reasonable interpretation consistent with this disclosure.
This application claims the benefit of the priority of US patent application No. 61/913192 filed 6 Dec. 2013 which is hereby incorporated herein by reference.
