Abstract
ABSTRACT OF THE DISCLOSURE
A fillet for use in holding a transparent sheet of glass or plastic spaced from artwork mounted in a picture frame. The fillet has a one-piece construction and is pro-vided with a recess and a spacer portion. Preferably, the fillet has a generally S-shaped body defining two recesses of different widths with each recess being defined by an end wall and an intermediate wall, the intermediate wall being common to the two end walls. Each end wall is angled rela-tive to the intermediate wall and the material of the fillet is resilient so that the end walls can yield away from the intermediate wall to accommodate glass or plastic sheets whose thicknesses are greater than the minimum widths of the recesses. The S-shaped fillet is reversible so that, in one position, it can receive a glass or plastic sheet of a rela-tively small thickness in one of the recesses and, in the other position it can receive a glass or plastic sheet of relatively large thickness in the other recess. In either case, the glass or plastic sheet is effectively spaced by the fillet from the artwork to prevent engagement of the sheet and the artwork.

Description
Thi~ invention relates to improvement6 in the mounting of artwork in a frame having a front glass or plas~
tic sheet through which the artwork is viewed and, more particularly, to an improved fille~ which forms a dual func-tion of gripping the edge margin of the glass or plastic sheet and spacing the sheet a safe distance from the artwork.
In mounting expensive artwork in frames, it is the normal procedure to mount a glass or plastic sheet or panel in front of the artwork to protect it against dust and mois-ture and other possibly damaging effects. It is also impor-tant to keep front sheet adequately spaced:from the artworkso that there will be no engagement between the two which would cause structural damage to the~:artwor~k such as ink transfer, mold growth (foxing) and buckling. Preferably dust and dirt particles should be kept out of the space between the sheet a~d ~he artwork so that ~he artwork is effectively preserved fox long periods of time and does not become dis-colored or otherwise affected:by foreign particles in the . space.
Attempts: have been made in the past to use spacers 25 to ~space the ~heet ~from the~ artwork. Balsa wood, plastic and , cardboard spacers have been used for this purpose. Such spacers have to be glued to the adjacent frame member. This tPchnique i~ not satisfactory because the glue often becomes loose, the spacers buckle, and ~he artwork lS not properly . .
.

5:~;
spaced ~rom the glass or plastic front sheet when this occurs. Also, the materials now used as spacers may them-selves cause damage to the artwork because of acid content or, if painted, paint transfer to the artwork.
Other attempts ha~e included the use of a trans versely C-shaped spacer which has been too small in thickness to space the artwork any more than l/16th inch away from the sheet. This spacer presents too small a space between the front sheet and the artwork because l/16th inch is an inade-quate space for many embossed, thick or naturally wav~ pieces of art.
The mounting of panels in frame members, such as window panes or the like, have been known in the past. Typi-cal disclosures of concepts of this type are set forth in 15 U.S. Patents 2,126,167, 2,189,137 and 2,308,918.
Because of the limitations of spacer units for frames for artwork which have been heretofore used, a need has arisen for an improved spacer or fillet which effectively spaces the transparent sheet in the front of the artwork from the artwork itself while permitting easy assembly of the artwork and sheet into a frame without special skills a~d tools.
The present invention satisfies the a~oresaid need by providing a device for use in mounting artwork in a frame haviny a transparent sheet spaced in fron-t of the artwork comprising: an elonyated fillet adapted to be placed in an operative position at the side of the frame member with the Eillet having an open-sided recess adapted to receive an outer edge margin of the sheet, the fillet having a trans-verse wall extending away from the recess to increase the height of the fillet, so that the fillet will form a space between the sheet and the artwork when the fillet is in said operative position.
Preferably, the fillet is of a resilient material, generally S-shaped in cross-section and is an extrusion which can be made of any length and cut to size for use with any particular picture frame. The S-shape permits the fillet to have two open-s-ided recesses instead of a single recess. When the fillet is made of resilient material a pair of opposed end walls formin~ parts of the fillet can yield outwardly of an intermediate wall of the fillet to increase the widths of the open-sided recesses formed by the end and intermediate walls of the fillet. In the case of an S-shaped fillet, one recess is wider than the other recess to accommodate sheets of different thicknesses. The S-shaped fillet is therefore reversible in a frame so that, for a relatively thin sheet, one of the recesses is used; whereas, for a relatively thick sheet, the other recess is used. In either case, the part of the fillet forming the recess not in use defines the spacer portion of the fillet.
The fillet of the present invention, thereore, operates to space a glass or plastic front sheet an adequate ~7~ L
distance from the artwork and to be self-retaining on the side margin of the sheet. Thus, the fillet wi.ll remain on the sheet during assembly of the artwork in a frame yet the fillet will substantially elim.inate the possibility of ink transfer, mold growth and buckling of the artwork.
In a further aspect the invention is a frame for artwork comprising: a number of frame members, the ends of the frame members being intexconnected together to form an opening for viewing the artwork, each frame member having an overhang near the opening; a fillet section for each frame member, respectively, each fillet section being transversely S-shaped to present a pair of spaced end walls and a pair of recesses near respective end walls, each recess having an open side, the width of one recess heing less than that of the other recess, one end wall of each fillet section being in engagement with the overhang of the respective frame member with the open side of one of the receCses of each fillet section being adjacent to the opening in the frame; a trans-parent sheet across the opening, the outer peripheral edge margins of the sheet being releasably recei~ed in the adjacent recesses of the fillet sections; a sheet of artwork engaging ~ .
the opposite end walls of the fillet sections; a bac~ing member behind the artwork sheet; and means securing the backing member to the frame members.
This invention is illustrated and compared with the prior art in the accompanying drawings in which:
D$~
Figure 1 is a perspective view of a section of one form of the fillet of this invention;
Figure 2 is a cross-sectional view through a typical frame showing the fillet of Figure 1 in use for spacing art-work from a glass or plastic sheet with the outer peripheralmargin of the sheet being received in one of the two recesses of the fillet;
Figure 3 is a view similar to Figure 2 but showing the outer margin of the sheet received in the other recess of the fillet of Figure 1, while the fillet spaces the sheet from the artwork;
Figure 4 is a front elevational view, partly in section of a complete frame showing the fillet of this inven-tion in sections at the sides and end of the frame;
Figures 5 and 6 are views similar to Figures 2 and 3 but illustrating prior art structure for spacing a glass c sheet from artwork in a picture frame; and Figure 7 is a fragmentary, cross-sectional view of a metal frame showing the fillet of Figure 1 in position to space artwork from a glass or plastic sheet.
The fillet of the present invention is broadly denoted ~y the numeral 10 and, in a preferred embodiment, has a cross section of the type shown in Figures 1-3. Fillet 10 includes a pair of spaced end walls 12 and 14, a pair of spaced sidewalls 16 and 18 connected to respective end walls -4a-12 and 14, and an intermediate, connecting wall 20 intercon-necting walls 16 and 18. Walls 12, 14, 16, 18 and 20 are preferably transparent, are integral with each other, and are formed from a suitable material which can be molded or extruded. A -typical material is polyethylene or butyrate.
Any suitable material can be used so long as the walls of fillet -4b-s 10 are relativ ly rigid yet the fillet has resilience at least at the junctions of adjacent walls. Transparency of the fillet allows the color of artwork behind the fillet to be seen when the fillet is in use.
Typically, sidewalls 16 and 18 are parallel with each other but end walls 12 and 14 are not paralIel. As shown in E'igs. 2 and 3, walls 12 and 14 are angularly dis-posed with reference to intermediate wall 20 when the fillet is not in u e. Walls 12 and 14 form with wall 20 respective open-sided recesses 22 and 24 and the width of the side openings of the recesses are effectively adjustable by virtue of the resilience of fillet 10 at the junction between walls 12 and 16 and at the junction between walls 14 and 18. The purpose of this adjustability is to permit a particular end wall, such as end wall 12 to be biased toward and bear against a sheet of glass ox plastic whose outer peripheral edge margin is inserted into the corresponding recess, such as recess 22. This effectively causes the fillet to be self-retaining on the shee~ so that the fillet will not buckle along its length. This feature is of importance when assembling the sheet and the artwork in a frame.
Recess 22 has a width sufficient to receive glass or plastic sheets which are relatively thin. Recess 24, on the other hand, has a width sufficient to permit it to receive relatively thick glass or plastic sheets.
If recess 22 is used, the remainder of the fillet, i.e., the portion of the fillet forming recess 24 defines a spacer portion extending transversely of recess 22 to in-crease the hPight of the fillet. Conversely, if recess 24 is used, the portion of the fillet forming recess becomes the spacer portion. Such spacer portion could be solid if only one reces~ is to be provided on the fillet. Instead of being solid, this spacer portion could be a single leg, such as wall 18 with wall 14 being omitted. Thus, in a broad sense, the fillet of this invention includes a recess portion and a spacer portion.
In use, with a picture rame 26 having a pair of side frame members 28 and a pair of end frame members 30, 5~
fillet 10 is cut into four sections lOa, lOb, lOc and lOd.
The fillet sections are shown in abuttment with each other.
They can be mitered, if desired. As shown at Fig. 2, fillet section lOb serves a dual function of receiving and being self-retaining on a glass or plastic sheet 32 and of spacing artwork 34 an adequate distance from sheet 32. One outer edge margin of sheet 32 is received in the corresponding recess 22 of fillet section lOb. Wall 12 of this fillet sectiQn is shown in surface-to-surface contact with the sheet butfis)could also be in line contact at the outer edge of the end wall if the thickness of the sheet is less than the maximum width of the recess. Fig. 2 shows that the opposite end wall 14 of fillet section lOb makes a slight angle with reference to the intermediate wall 20 of the fillet section.
A backing panel 36 engages the rear surface of artwork 34 in the usual manner and brads or nails anchor the backing member 36 to the sides and ends of the frame.
Fig. 4 shows the four fillet sections in place in a completed frame. When so completed, the fillet sections engage the inner surfaces 38 (Fig. 2) of the overhangs or rabbits 40 of the frame members 28 and 30. Moreover, the junctions between a pair of adjacent fillet sections (Fig. 4) can be coupled together for continuity purposes.
Assembling the illet sections, t~e sheetl the artwork and the backing member 36 in the frame is a simple matter because these components c~n be formed in a sandwich and dropped simultaneously into the frame from the rear.
Then the backing member is secured to the frame members in the usual manner to complete the assembly.
Fig. 3 shows a relatively thick sheet of glass or plastic 32a in place of relatively thin sheet 32 (Fig. 2).
In such a case, the fillet sections are reversed so that the outer edge margins of sheet 32a are received in the corres-ponding recesses 24 of the fillet sections. Again, end walls 14 of the fillet section~ yield ~lightly outwardly to receive the outer edge margin~ of the sheet, whereupon the end walls 14 can either be in line contact at their outer maryins or can be in surface-to-surface contact with the sheet depending ~L~7~
o upon the thickness ~f the sheet. The assembly of the frame with the artwork is accomplished in the same way with sheet 32a as described above with respect to sheet 32.
Fig. 5 shows one form of a prior art device typi-cally used with frame 26. Ik comprises a balsa wood spaceror section 44 which usually is bonded to the adjacent frame member. Besides the acid content of the wood burning the adjacent artwork, the natural color of the wood makes it viewable through the glass sheet 46 so that the balsa wood should be painted to provide a professional look to the completed frame. This painting requires additional labor which is not required with fillet 10 because the fillet can be made essentially transparent so as not to be observable through the sheet 32. Also, painting will possibly result in some paint transfer to the artwork. Because the balsa wood is bonded by glue or adhesive to the frame, the glue can come loose and when this occurs, the balsa wood droops and re-~lires replacement to provide the necessary support for artwork 48 and backing member 50.
Another form of prior art device is the transversly C-shaped extrusion 52 having spaced sides 54 as shown in Fig.
6. A primary limitation of extrusion 52 is that it permits only a 1/16 inch clearance 58 between sheet 56 and artwork 60. This is not enough clearance to prevent engagement of sheet 56 and artwsrk 60. This problem is avoided at all times by the relatively large space between the sheet and the artwork when using fillet 10. Also, extrusion 52 is designed primarily to protect sheet 56 from breakage. It is not designed for use as a fillet and, if so used, is not properly u~ed.
Another prior art frame is of one of the type made of metal frame members 70 having the cross section shown in E'ig. 7. Fillet 10 can be used with this type of frame. Use of fillet 10 with this frame eliminates the tedious job of placing the fourth side on the frame when the sheet of glass or plastic, the artwork and the backing member are in the frame formed by the other three sides. The reason for this is that the spacers between the glass or plastic sheet and ¢~D5~
the artwork must be bonded by an adhesive to the inner sur-faces of the sides. After connecting the three sides to-gether, the sheet of glass or plastic must be slid in place between the rabbits on the frame sides and the spacers, a very tedious job since any excess adhesive in the groove receiving the marginal side edges of the sheet will inhibit movement of the sheet into its operative position. Putting the fourth side in place re~lires that the fourth edge of the sheet be accurately received in the groove of the fourth side; also a very tedious job. When the fourth side is put into place, the artwork and backing member must be kept behind the spacers. Then, when the fourth side is in place, the artwork and backing members are manually forced forwardly against the spacers and leaf springs are put in place behind the backing member.
All of the foregoing steps take great manual dex terity and still the resulting asse~bly is not entirely satisfactory. The reason for this is that, using spacers bonded to the frame sides as described above, the spacers can ~0 come loose and sag due to gravity, thus leaving the artwork without proper front support. The spacers become separated from the frame sides ~ecaus~ the leaf springs place the spacers in shear. Since fillet 10 is releasably rètained on the sheet, it will not buckle ~r become separated from the sheet and this feature will assure that the artwork will be properly supported at all times.

The fillet of the present invention is broadly denoted ~y the numeral 10 and, in a preferred embodiment, has a cross section of the type shown in Figures 1-3. Fillet 10 includes a pair of spaced end walls 12 and 14, a pair of spaced sidewalls 16 and 18 connected to respective end walls -4a-12 and 14, and an intermediate, connecting wall 20 intercon-necting walls 16 and 18.
