Abstract
An assembly (20) of artwork (21) and backing (22) wherein a combination of floater anchors (24), hard anchors (26), and soft anchors (25) produce a floatability of artwork about its backing and which eliminates curling or rippling to it due to temperature and humidity changes. The floater anchor (24) is formed from a pair of tape pieces (35-1, 35-2) fastened together by a pair of crossing ties (37, 38) that interlace the pieces (35-1, 35-2). Piece (35-1) is adhered to artwork (21) and piece (35-2) is adhered to backing (22), whereby artwork (21) can shift about backing (22) to the extent of the spacing distance between the attachment, such as by glue spots (40), of ties(37, 38)to pieces (35-1, 35-2). Hard anchors (26) are formed by providing ribbons (42) of glue between pieces (35-1, 35-2) and ties (37, 38) so that the pieces (35-1, 35-2) do not shift between each other. Soft anchor (25) is a state-of-the-art element, however, in utilization of this invention, prevents swinging and pivoting of artwork about an applied hard anchor (26) as well as supporting for the weight of artwork (21) on backing (22).
Description




TECHNICAL FIELD




This invention is directed to a system and method of preparation for mounting an artwork in a floatable mode upon its backing, and the assembly thereof, and by which curling, rippling, or other deleterious or deteriorating effects on the artwork due to changes in temperature and humidity are eliminated.




BACKGROUND TO THE INVENTION




My U.S. Pat. #5,437,428, granted Aug. 1, 1995, discloses an earlier picture frame mount over which the instant invention is an advance. The listed patents (by their numbers) therein together with the prior art references made of record in the prosecution of that patent disclose data pertaining to mounting an artwork on a backing.




SUMMARY OF THE INVENTION




This invention involves utilization in one or more combinations of soft, hard, and floater anchors affixed to both a work of art on paper [hereinafter “artwork”] and a backing sheet [hereinafter “backing”] to which the artwork is to be mounted and sustained thereon; and further to the assembly of these elements and by which the artwork floats on its backing. Temperature and humidity detrimentally or deleteriously affect an artwork directly mounted to a backing, i.e., being attached directly to one another, resulting in the curling or rippling of the artwork as temperature and/or humidity affect it over a period of time, distorting it in kind or degree, thus the artwork losing its value. With a truer floatability available for the artwork and its backing, the expansion or contraction of the artwork's substance because of temperature and humidity changes do not alter the fine character of the artwork floated to the backing.




In the assembly of artwork to backing in this invention, a step-wise preparation is undertaken prior to the actual mounting of artwork to backing, utilizing this invention. There is first a useful step of locating the position of the artwork on the backing by indicating on the backing a boundary for the artwork, so that a desired finished arrangement or assembly between the two is achieved. The use of an indicium/indicia placed on the backing, such as a reference line, e.g., a center line, assists at this point in the preparation. Then, in a series of steps (not necessarily in the order herein immediately or hereinafter described) one or more in number of floater anchor members, or in combination with one or more soft anchor, and/or hard anchor members, at particular or spaced points are applied on the backing, prior to mounting the artwork on the backing. The floater anchor members, in number or in combination with one or more of the soft and/or hard anchor members, provide the feature and advantage of a truer floatability of the artwork relative to its backing over previous advances in the art, upon applying the artwork thereto. The hard anchor members are formed from a floater anchor member, however, its components fastened together in a different manner than that for the floater anchor members.




In more particularity, a floater anchor is a pair of suitably-sized pieces joined together, one over or on top of the other, by a pair of connecting ties in the form of strips, in such a manner that the first piece can move or shift in a gliding or sliding motion relative to the second piece to the extent of clearance from attachment in the distance between the attaching points of the ties to their respective or corresponding pieces. Each piece includes a neutral or non-adhesive side to which a corresponding tie is secured at such points and by which the pieces are interlaced to each other. The first tie secured to the first piece undercrosses the second tie that is secured to its second piece, effecting such interlacing on the facing neutral or non-adhesive sides of the pieces. Adhesive materials or characteristics are disposed on the non-facing or outer sides of each of the joined pieces. Thus, the adhesive side of the first piece is ready for attachment to an artwork and the adhesive side of the second piece is ready for attachment to its backing, and a truer floatability of artwork to backing is achieved when used in the process or method of assembling artwork to a backing.




A hard anchor is formed from the elements of a floater anchor, however, being fastened together in a manner not the same as with the floater anchor.




An object of this invention is to eliminate rippling and/or curling to an artwork when mounted to its backing.




Another object of this invention is to provide a floatability between artwork and its backing when mounted to one another and by which rippling and curling of the artwork is eliminated.




Yet another object of this invention is to provide various arrangements and combinations of tape-like members that connect the artwork to its backing to attain such floatability.




Still another object of this invention is to provide or retain a facile application or method of mounting an artwork to its backing with the practice of this invention.




Still another object of this invention is to prevent sagging or change of the artwork's positioning in its assembly to its backing.




A further object of this invention is to prevent damage to the artwork during handling, shipping, or turning the assembly around and/or up-side down or in other directions, which in instances cause damage thereto.




These and other objects and advantages will become more apparent upon a full and complete reading of the following description, the appended claims thereto, and the accompanying drawing comprising two (2) sheets of twelve (


12


) FIGURES.

PREFERRED EMBODIMENT OF CARRYING OUT THE INVENTION




Referring now to the drawing wherein reference characters correspond to like numerals hereinafter,

FIG. 1

illustrates a finished assembly


20


of an artwork


21


to a backing


22


produced by the assembly or mounting between them and as connected by the utilization of one or more combinations of one, some, or all of a group or series of floater anchor members


24


,

FIG. 3



d


, soft anchor members


25


,

FIG. 4

, and hard anchor members


26


,

FIG. 2

, respectively. [Note: the artistic rendering of artwork


21


illustrated in

FIG. 1

is removed in

FIG. 2

for the purpose of clarity in the description of subject matter of the invention.] As a starting consideration for practice of the invention with these anchor members, various ways to position an artwork


21


over its backing


22


is first undertaken. As an example of such consideration,

FIG. 5

, wherein the topside


28


of backing


22


is illustrated, one or more of a number of indicia


29


are applied at appropriate points or lengths to topside


28


for locating or spotlighting a desired boundary


30


on the backing


22


and to which artwork is to be bound in the finished assembly with backing


22


. Pencilled lines


31


also can be imposed on backing


22


to locate a boundary


30


. Indicia


29


take the form of conveniently sized one-sided adhesive members, such as a self-stick note sheet exemplified by a “Post-it”[™] removable note sheet commercially available and made by the 3M Company, St. Paul, Minn., USA. Usually the boundary


30


of an artwork


21


is of a rectangular dimension, although an indicium


29


may include a curvilinear edge as well to coincide with a like edge for an artwork


21


and having its curvilinear edge positioned along points or lengths of a curvilinear boundary


30


previously identified or located on backing


22


. Elongated weights (not illustrated) of an appropriate or suitable size and length also may provide the manner or way by which location of the artwork's boundary


30


can be determined on backing


22


. A length of masking tape (not illustrated ) is suitable as an indicium


29


, however, it should not be manually pressed hard to backing


22


but faintly pressed in a manner so as not to damage backing


22


itself, as well as being readily removable prior to mounting an artwork


21


to backing


22


.




Turning to

FIG. 2

, a “hard anchor” member


26


, more fully described hereinafter, now is manually applied to backing


22


at or on a planned line


32


as a reference point or center line for placing of artwork


21


on backing


21


. Member


26


is applied within the confines of boundary


30


, such placement preferably adjacent to or near the top edge of the boundary


30


for artwork


21


. Hard anchor member


26


facilitates the preserving of an artwork removed from its backing should the removal of artwork from backing be required or desired.

, having an adhesive characteristic on its one side and a neutral or non-adhesive characteristic on its other side. The product, “filmoplast SH” [™], made in the form of a roll of tape, commercially available from Neschen Corporation,


2201


Brentwood Road, Suite 114, Raleigh NC. 27604 USA, readily provides a convenient single material that includes both the adhesive and neutral non-adhesive characteristics in a tape which can form a floater member


24


. This product also is conducive to the formation of the soft and hard anchor members


25


,


26


, respectively, as well, for practice of this invention. The product is an acid-free product and is made of a fine threaded white linen material coated with an exceptionally strong water-based self adhesive

utilized in the practice of the invention.




A floater anchor member


24


is formed in a suitable size from two (2) pieces


35


-


1


,


35


-


2


of material


35


,

FIGS. 3

, and to which a pair of ties


37


,


38


are fastened by specific spaced spots or globs


40


of glue


40


,

FIGS. 3

,


3




c


. Ties


37


,


38


are in the nature of ordinary strips of paper. Each of the pieces


35


-


1


and


35


-


2


is made by cutting a pair of generally-equally sized pieces from a material


35


, such as from the “filmoplast SH” [™] tape and are suitably sized in relation to a particular assembly


20


of sized artwork


21


and its backing


22


. A first tie or strip


37


, shown in phantom in

FIG. 3



b


, is laid generally midway the length of the white linen material


35




n


and across the material's width as shown in solid lines in

FIG. 3



b


. Four (4) spots or globs


40


of fastening glue are applied as shown in

FIG. 3



b


, two (2) on the (white linen) piece


35


-


1


next to its opposing end edges and spaced a distance from each other, and two (2) to the topside of the tie


37


adjacent the lateral opposing edges of piece


35


-


1


and spaced a distance from each other. An end of a pin, a pointed end of a razor edge, a paper clip end, are examples (not shown) of an applicator by which the four (4) globs of glue are manually applied to their described points on piece


35


-


1


and tie


37


. A second tie


38


is laid over the first laid tie


37


,

FIG. 3



c


, this time midway the lateral opposing edges of piece


35


-


1


while extending to the opposing end edges of piece


35


-


1


, becoming fastened by its specific spots


40


of glue to the white linen side of the “filmoplast SH” [™] material (


35


). The white linen side


35




n


of the second piece


35


-


2


of the “filmoplast SH” [™] material (


35


) then is caused to face and be mounted over piece


35


-


1


,

FIG. 3



d


, becoming fastened to the two (2) specific spots or globs of glue


40


directly applied to the first laid tie


37


mounted on the white linen side


35




n


of piece


35


-


1


. In other words, tie


37


is fastened to a material piece (


35


-


2


) to which it is not contiguous at its crossing area with tie


38


, and tie


38


is fastened to a material piece (


35


-


1


) to which it is not contiguous at its crossing area with tie


37


. The result is, after the drying of the spots or globs


40


of glue, and the crossing areas of the ties


37


,


38


to one another, that the pieces


35


-


1


and


35


-


2


are interlaced to each other, without them separating from each other and having the capability of shifting between each other to the extent of the distances that space the spots of glue that have connected the ties


37


,


38


to their corresponding pieces


35


-


1


,


35


-


2


. Preferably, the ends of ties


37


,


38


that project past the edges of pieces


35


-


1


,


35


-


2


are cut off. In action as utilized in the assembly of artwork to backing, the joined two pieces


35


-


1


,


35


-


2


shift with respect to one another in terms of a slipping and/or guiding motion. A ¼″ shifting motion has been found to be of a satisfactory extent as the artwork's substance expands or contracts under changes of temperature and humidity. Rippling and curling of artwork


21


when assembled to its backing


22


is prevented; and perhaps the same for other reasons as well, such as handling, shipping, etc., damage to the artwork does not occur. The artwork


21


floats free of the backing


22


under such conditions.

c


to ties


38


(via piece


35


-


1


),


37


, ribbons


42


of glue are laid first on neutral member


35




n


of piece


35


-


1


in continuous lines of glue (or other fastening elements) in the form of a cross. Ties


37


,


38


are then placed on piece


35


-


1


as illustrated in

FIG. 3



c


, and thereafter, ribbons


42


of glue are applied to the exposed surfaces of the ties


37


,


38


. Then piece


35


-


2


is applied or glued to both ties


37


,


38


. Upon drying of the ribbons


42


of glue, pieces


35


-


1


and


35


-


2


are fixed to one another, without the capability of motion between them. Preferably the ends of ties


37


,


78


which project past the edges of pieces


35


-


1


,


35


-


2


are cut off. The purpose of forming hard anchor


26


in this manner, rather than merely glueing together two (2) pieces


35


-


1


,


35


-


2


or the like, is to provide preparation for ease of release of backing


22


from artwork


21


without damaging the latter, should a different or second backing be subsequently utilized.




One or more soft anchor members


25


,

FIGS. 2

,


4


, are manually applied to and at various locations on backing


22


and within boundary


30


, their number, if used, depending upon the size and weight of artwork


22


which in turn assist in determining their number. These soft anchor members


25


are state-of-the-art fasteners, as described in and illustrated in

FIGS. 7-11

of the noted U.S. Letters Pat. No. 5,437,428 and their disclosure in that patent are incorporated herein by reference thereto. A members


25


takes the form of a tape piece configured, for example, as by a scissor cutting, from the product “filmoplast SH” [™] tape and are manually applied to backing


22


within boundary


30


of artwork


21


, i.e., so that they are out of view after artwork


21


is mounted and assembled to backing


22


. Generally, a suitable number of members


25


are disposed in and at spaced locations or points on backing


22


as illustrated in

FIG. 4

within the artwork's boundary


30


, in order to support the weight of the substance of artwork


21


, yet not preventing floatability of artwork


21


by floater anchor members


24


.




In carrying out practice of the invention, the following description of steps is to be considered illustrative as one way in which to properly mount artwork to backing with the anchors disclosed herein, and it should not be considered as the only way to effect an effacacious mounting. A backing


22


is laid on a flat surface (not shown), such as a table top. Boundary


30


is first determined on backing


22


and indicia


29


mounted to the topside


28


of backing


22


,

FIG. 5

, to assist in subsequently placing one or more of the kinds of anchor members


24


,


25


,


26


at suitable locations or points on backing


22


. A hard anchor member


26


is applied to backing


22


along a reference line or point


32


,

FIG. 2

, at the top of but within the boundary


30


for the artwork


21


. Usually four (4) floater anchor members


24


,

FIG. 2

, are applied to the backing


22


within the boundary


30


and within confines of corners of artwork


21


, and at other locations determined for artwork


21


at suitable points in confines of corners of artwork


21


as well. One or more soft anchor members


25


,

FIGS. 4

,


2


, are applied, preferably to the extreme left and right, near the top, of artwork


21


, to prevent pivoting or swinging of the artwork about hard anchor member


26


. Also, one or more of them can be applied where necessary to support the weight of artwork to backing, where it is deemed best for such support. These applications of members


25


occur upon removing the protective coating or film


36


from the material


35


forming soft anchor member


25


but with removal at this point in the assembly only on one of its sides to expose its adhesive coating


43


,

FIG. 4

, for manual application to the backing. The other adhesive side of anchor


25


remains protected by film or protective coating


36


(not shown in

FIG. 4

) until a later step in assembly.




With all applied anchor members


24


,


25


,


26


(or lesser number and/or kind if that be the case) now mounted to topside


28


of backing


22


, the protective coating


36


is removed from all of them, to expose the adhesive coating


35




c


on them. As to each anchor member


24


, the position of its material piece


35


-


2


to its material piece


35


-


1


is adjusted by shifting it so that it is directly over piece


35


-


1


in order to provide as much shifting in its motion as possible, such motion being translated into floatability for artwork


21


once firmly mounted to backing


22


. Artwork


21


now is ready to be mounted to backing


22


. It is carefully placed upon backing


22


within boundary


30


. The artwork is first pressed hard immediately over hard anchor


26


and then manual pressure applied on artwork


21


immediately over or in line with the positions of the exposed adhesive coatings


35




c


of the in-place anchor members


24


, and to anchor members


25


as well should they have been applied on backing


22


. As much floatability as possible for artwork


21


on backing


22


has been achieved.




In the event that subsequently backing


22


is to be removed from artwork


21


, it is apparent that backing


22


can be cut from each of the anchor members


24


,


25


,


26


, if any one or some or all of them have been applied in a particular assembly


20


, although portions of them remain on the backside of artwork


21


. Nevertheless, the artwork is not damaged as its paper or substance has not been severed by such cutting.




Each of the anchor members


24


,


25


,


26


is readily made at the time of preparing assembly


20


for a particular artwork and backing, by cutting strips of paper


37


,


38


and material


35


as exemplified by the “filmoplast SH” [™] tape product into their corresponding shapes.




Various changes and modifications of the anchor members themselves may be practiced without escaping or departing from the scope and/or spirit of the appended claims hereto. Preferably the anchor members


24


,


25


,


26


are preformed prior to any one of them being actually used in assembling a particular artwork


21


to a backing


22


as well as making or forming one or more of them at the time of a particular assembly


20


of artwork


21


to backing


22


. The invention is not limited in its practice by use only of the “filmoplast SH” [™] product.
