It embodies a frame system for holding a normally flat picture sheet and bending it into a one dimensional concavo-convex shape for adding a three dimensional effect to its display. It also creates an arch- shaped void space in front of the displayed picture for housing and displaying a three dimensional articles and/or reinforced pictures complementary to said first picture. Magnetic means are also employed for magnetically supporting these three dimensional articles and/or reinforced pictures in the frame system.
  • the frame system 1100 shown in Fig. 35 includes a frame body 1102, backboard 1104, first transparent plate 1106, second transparent plate 1108, and a backing plate 1110. It may also include one or more magnets 1112 and 1114. Also shown in Fig. 35 is a flat custom picture 1116 to be mounted in the frame system 1100.
  • the frame body 1102 has a rabbet 1118 and a largely flat frame window 1120 through which all pictures are to be displayed.
  • the backboard 1104 is hinged on the frame body 1102. It is horizontally rotatable between an open position as shown in the figure and a closed position. It can be locked in its closed position using means such as latch 136 and catch 138 of Fig. 2 or any conventional clip means.
  • an easel 1122 Located on the back side of the backboard 1104 is an easel 1122 for placing the frame system 1100 on a table in a tilted position. This easel 1122 is not shown but can be similar to the easel 680 in Fig. 13.
  • the first transparent plate 1106 is a flat rectangular plate.
  • the second transparent plate 1108 has a width and height same as that of the first transparent plate 1106 but is curved. It can be made of plastics through conventional molding or plastic thermal curving process. As seen in the figure it has a curvature in the horizontal axis in the shape of an arc and can thus be termed one-dimensional concavo-convex.
  • the backing plate 1110 has a size and curvature largely same as that of the second transparent plate 1108.
  • the backboard 1104 will press the backing plate 1110 forward which in turn will bend the picture 1116 until the picture 1116 is bent to the same curvature as that of the second transparent plate 1108.
  • This curvature will add a three dimensional effect to the illustration on the picture 1116. This is true regardless whether the illustration is a scenery or a close up item such as a bowl of fruits.
  • the picture 1116 is a flexible sheet such as a photographic paper; and (2) the thickness of the stack with the picture bent is about the same as the depth of the rabbet 1118 in the frame body 1102.
  • the second transparent plate 1108 and the backing plate 1110 are normally rigid, but also can be somewhat flexible as long as the final thickness of the stack can be made to meet the above criteria.
  • This void space is usable for housing a three dimensional article such as a small figurine complementary to the picture on display. Further discussed in the following is a novel magnetic means for holding such a three dimensional article in the void space.
  • the bottom surface of the rabbet 1118 is covered by a magnetic strip 1124 which in turn covered by a black vinyl adhesive tape 1126.
  • This magnetic strip 1124 is preferably made of ferromagnetic material such as iron or steel.
  • the adhesive tape 1126 serves to attach the magnetic strip 1124 to the rabbet 1118 and to protect it from rust and to provide a natural black background.
  • the backing plate 1110 is shown made of a curved magnetic sheet 1128 which is covered on each side by a lamination layer 1130.
  • the magnetic sheet is preferably a steel sheet with a thickness of 0.010" (0.25 mm) or less.
  • the lamination layer 1130 can be a conventional adhesive -coated plastic sheet of 0.003" (0.076 mm) in thickness.
  • the lamination layers 1130 serve to protect the magnetic sheet 1128 from rust.
  • the size of the lamination layer 1130 should be slightly larger than that of the magnetic sheet 1128 so that all edges of the magnetic sheet 1128 are covered by the soft lamination sheets 1130 for easy handling.
  • the magnetic sheet 1128 needs to be made curved.
  • the magnetic sheet 1128 is a full hard cold rolled low carbon steel of 0.007" (0.18 mm) or less in thickness it is quite flexible.
  • a curved sheet such as a duplicate second transparent plate 1108 can be placed behind the magnetic sheet 1128 to force such curvature on the backing plate 1110 when mounted.
  • the magnet 1114 is a commercially available magnet strip typically coated with an adhesive on one side which is covered by a easily removable protective sheet 1132. This strip can be cut to any length desired with a scissors.
  • the ceramic magnet block 1112 or magnet disc, not shown, are generally stronger magnet for its size and are widely used for craft.
  • a three dimensional article such as a figurine of suitable size can be displayed in the frame system 1100 by first attaching one or more magnets 1112 or 1114 to the bottom or back of the article. This article can then be placed either on the adhesive tape 1126 or the second transparent plate 1108 and be magnetically held by the magnetic strip 1124 or the magnetic sheet 1128.
  • the first transparent plate 1106 mainly serves to shield and protect the three dimensional article placed behind the first transparent plate 1106. But on the other hand, there are advantage by not having this first transparent plate 1106 at all.
  • the second transparent plate 1108, the picture 1116 and the backing plate 1 110 can just be assembled in one stack and placed in the frame body 1102.
  • the backboard 1104 is next closed and locked. This will bend the picture 1116 and rest the second transparent plate 1 108 against the rabbet 1118. Consequently an arch-shaped void space is again formed between the flat frame window 1120 and the curved transparent plate 1108. In this way one can access this void space any time through the frame window 1120 for placing and rearranging the three dimensional articles for display along with the displayed picture 1116.
  • Fig. 36 discloses a front body 1140 which can be hinged on the frame body 1102 in Fig.
  • this front body 1140 Carried on this front body 1140 is a flat transparent plate 1 142 mounted over a front body window 1144 of the front body 1140.
  • This flat transparent plate 1142 serves as a substitute for the first transparent plate 1106 shown in Fig. 35.
  • this flat transparent plate 1142 serves to shield and protect the three dimensional article placed in the frame system 1100.
  • FIG. 37 is a new type of reinforced picture that can be easily made for display in the frame system 1100.
  • a new reinforcement sheet 1150 is shown which can also be supplied as part of the frame system 1100. It is a Mylar sheet 1152 with one side coated with a layer of adhesive which is covered by a removable protective sheet 1154.
  • the Mylar sheet 1152 is chosen for its tough, durable, lay-flat characteristics. Most importantly, it can be easily cut to any intricate shape with a simple household scissors when its thickness is less than 0.015" ( 0.38 mm).
  • FIG. 37 Also shown in Fig. 37 is a picture 1156 showing an illustration of an eagle.
  • a reinforced picture of this eagle can be made by first lifting and cutting off one portion of the protective sheet 1154 to expose enough area of the adhesive on the Mylar sheet 1152 for the picture 1156. The picture sheet 1156 is then laid on the exposed adhesive.
  • the reinforced picture of the eagle can now be made by simply cutting along the outline of the eagle using a scissors.
  • the above- described eagle reinforced picture is ideally mountable on the second transparent plate 1 108 of the frame system 1100 with the use of one magnet block 1112 applied with a layer of adhesive. This magnet block 1112 can be attached to the back of the reinforced picture and be oriented vertically for mounting on the curved second transparent plate 1108.
  • the eagle reinforced picture is now magnetically held and displayed in front of the picture 1116. Because of the reinforcement sheet 1150 an eagle illustration is shown firmly flat and spaced apart from the picture 11 16 which further enhance
  • Fig. 38 shows the first example of an assembled frame system of the present invention.
  • This frame system 1160 includes all components shown in Fig. 35 and described above. Mounted in this frame system 1160 is a scenery picture 1162 which would appear three dimensional if viewed in the actual frame. Also mounted in front of the picture 1162 are an eagle reinforced picture 1164 and several animal figurines 1166. All animal figurines 1166 are attached with the magnets 1114 and mounted on the vinyl tape 1126 and magnetically held by the magnetic strip 1124.
  • the eagle reinforced picture 1164 is made exactly as described above and is mounted on the second transparent plate 1108 and magnetically held by the backing plate 1110.

  • Fig. 38 discloses a new three dimensional picture frame display. It allows a user turn an ordinary flat picture into a curved three dimensional display. In the mean time an arch-shaped void space in front of the picture is created for housing one or more figurines and photo sculptures complementary to the picture. The result is an interesting three dimensional show. More importantly, the reinforced picture of the present invention can be easily made. The mounting of such reinforced pictures and three dimensional articles can also be easily achieved.
  • Fig. 39 shows another example of the assembled system of the present invention.
  • a bridal picture which would appear three dimensional if viewed in the actual frame.
  • a reinforced picture 1174 commemorating such an important day in her life.
  • This reinforced picture 1174 is attached with a magnet 1112 on its back. It is mounted on the Vinyl tape 1126 and is magnetically held by the magnetic strip 1124.
  • the frame should be placed in such a way so that the line of sight between the frame and the viewer's eyes is perpendicular to the plane of the frame. Since this frame is usually placed on a table at a level lower than that of the viewer's eyes, it is highly recommended that the frame be tilted which makes the easel 1122 of the frame system 1100 very desirable.
  • Fig. 41 discloses an improvement on the frame system 1100 of Fig. 35 by providing a novel holder 1180 which can be joined to the backboard 1104 of the frame system 1100 using a pair of bolts 1182 or other suitable means.
  • This holder 1180 is made of a flexible plastic sheet which is curved horizontally to an one dimensional concavo-convex shape as shown in the figure.

  • the transparent sheet 1188, the picture 1116 and the magnetic sheet 1190 are next gathered as a stack in the order as shown in the figure. This stack is slid into the two channels 1186 until it is stopped at the stud 1184. At this time the picture 1116, as well as the transparent sheet 1188 and the magnetic sheet 1 190 will be bent to a curvature same as that of the holder 1180.
  • any three dimensional articles or reinforced picture to be displayed can now be placed either on the vinyl tape 1 126 to be magnetically held by the magnetic strip 1124 or on the transparent sheet 1188 to be magnetically held by the magnetic sheet 1190.
  • the backboard 1104 can be closed and locked which completes the mounting process.
  • the assembled frame system is ready for display. It will be seen that the installed picture 1116 is curved which imparts a three dimensional effect to the illustration in the picture 1116. The installed three dimensional articles or reinforced pictures are also displayed in front of the picture 1116.
  • Fig. 42 discloses another version of the holder of present invention.
  • This holder 1192 is made of ferromagnetic metal sheet such as iron or steel and is formed by stamping or other suitable means. It has a vertical portion 1193 and a horizontal portion 1194. A small elbow 1195 integrally joins above two portions.

  • the horizontal portion 1 194 is a flat rectangular plate which allows the holder 1192 to stand on a table.
  • the transparent sheet 1188 and picture 1116 of Fig. 41 are also shown in Fig. 42.
  • the magnetic sheet 1190 of Fig. 41 is no longer needed for the holder 1192 which is itself magnetic.
  • the picture 1116 is mounted by simply inserting the picture 1 116, together with the transparent sheet 1188, down the two channels 1196 until they are rest on the horizontal plate 1194. After installation, both the picture 1116 and the transparent sheet 1188 will be bent to a curvature same as that of the holder 1192.
  • any three dimensional articles or reinforced pictures to be displayed can now be placed on the horizontal plate 1194 or the transparent sheet 1188 and be magnetically held by the holder 1192.
  • the assembled holder 1192 can then be placed in the frame body 1102 after which the backboard 1104 is closed and locked.
  • the finished frame system 1100 shall then be ready for display.
  • the holder 1192 is rigid and fixed in its dimension. In order to fit the holder 1192 snugly in the frame system 1100 the depth of the holder 1192, plus the thickness of the first transparent plate 1106 if present, shall be equal to the available depth of the rabbet 1118. The width and height of the holder 1192 should also match that of the rabbet 1118 to assure a good fit.
  • the width of the transparent sheet 1188 is also very critical for it to be properly bent into a curvature same as that of the holder 1192.
  • the horizontal width of the transparent sheet 1188 should be equal to the length of the arc in the holder 1192, as viewed from the top, extending to the ends of two channels 1196. Too wide the width will cause the transparent sheet 1188 to bend out of shape, while too short the width will prevent two ends of the transparent sheet 1188 to touch the channels for proper bending.
  • the width of the picture 1116 should not be too wide to fit into the two channels 1196. However, a narrower picture will still fit and be properly curved as long as it is sandwiched between the curved holder 1192 and the curved transparent sheet 1188.
  • Figs. 43-46 disclose one more innovative feature in the 3D picture frame of the present invention. This feature is schematically shown in Fig. 43.
  • a pre-curved glass 1202. a custom picture 1204, and a pre-curved backing plate 1206 are intended to be mountable in the frame body 1102 of the frame system 1100 of Fig. 35, in the same manner as the second transparent plate 1108, picture 1116, and the backing plate 1110, respectively.
  • top edge glass 1208 is positioned between the top edge of the pre-curved glass 1202 and the top member of the frame body 1102.
  • bottom edge glass 1210 is positioned between the bottom edge of the pre-curved glass 1202 and the bottom member of the frame body 1102 in the mounted position.
  • top edge sheet 1214 can be inserted between the top edge glass 1208 and the top member of the frame body 1102.
  • the bottom edge sheet 1216 can be inserted between the bottom edge glass 1210 and the bottom member of the frame body 1102. It is clear from Fig. 43 and the above description that, once mounted in the frame body 1102, the top edge sheet 1214 and the bottom edge sheet 1216 are positioned perpendicular with respect to the custom picture 1204. It is also clear that the top edge sheet 1214, bottom edge sheet 1216 ane the custom picture 1204 are all visible through the glasses 1208, 1210 and 1202, respectively. The significance of these two facts will be clear by the three examples shown in Figs. 44-46 and described in the following discussion.
  • a picture 1222 of a group of children is displayed in a 3D picture frame 1224.
  • This picture frame 1224 is structurally similar to the frame system 1 100 of Fig. 35 and includes the pre-curved glass 1202, pre-curved backing plate 1206, and the edge glasses 1208 and 1210 as shown in Fig. 43.
  • the picture 1222 will be curved when it is sandwiched between the curved glass 1202 and the backing plate 1206. The very nature of this curvature will impart a 3D effect to the picture
  • Composition in a picture may also be employed to enhance its 3D effect.
  • One good way to achieve this 3D effect is to take a picture of a large group of people packed together against a structureless background such as wall, lawn, sky, etc. The image of these people, when curved up in this 3D frame, will appear to "float" above the background - an interesting 3D effect.
  • a top edge sheet 1226 and a bottom edge sheet 1228 are also shown in Fig. 44.
  • the top edge sheet is not visible in the frame 1224.
  • edge sheets 1226 and 1228 contribute to the overall aesthetic appearance of the picture presentation.
  • a foreground covered by natural "grass” is certainly more appealing than the bare frame rabbet.
  • Figs. 45a and 45b disclose another novel concept in the making of the edge sheets. In Fig.
  • top edge sheet 1226 and the bottom edge sheet 1228 are chosen separately from the main picture 1222. But in Figs. 45a and 45b the edge sheets and the main picture can be taken from a single original picture sheet.
  • the picture sheet 1230 in Fig. 45a shows a group of dancers 1231, a floor 1232, and a wall 1233. A portion of the picture sheet 1230 is shown trimmed off to form a top edge sheet
  • edge sheets 1234 and 1235 can be mounted in the 3D picture frame 1224 in the same manner as the top edge sheet 1226.
  • the first one is the cost economy and convenience. But most importantly, it will be assured that the obtained edge sheets will more likely match the main picture in color and pattern since they are all obtained from a single picture sheet.
  • the dancers 1231 are literally surrounded in three dimension by the same floor 1232 and the same wall 1233 appeared in the edge sheets 1234, 1235 and the main picture 1236. It achieve a wrap-around effect which further strengthens the 3D feeling in the mind of the viewer.
  • the picture sheet 1237 shown in Fig. 45b can also be similarly trimmed to form a top edge sheet 1238. a bottom edge sheet 1239 and a main picture 1240. They can also be mounted in the 3D frame 1224 for achieving wrap-around effect and superb 3D effect.
  • the picture sheet 1237 is more likely obtained in a studio. Many professional cameras generally yield photographs with square or near square formats. Such photographs will be excellent candidates for making such 3D presentation in a frame of rectangular shape.
  • FIG. 46 discloses a novel 3-piece mat set 1241 that are mountable in the 3D frame of the present invention.
  • the present mat set 1241 includes a center mat 1242 which is just like a conventional mat with a bevel cut opening. It can be sandwiched between a curved glass and backing plate of proper size and be curved when mounted in a 3D frame of the present invention. A picture can be attached to the backside of the center mat 1242 and also be curved to exhibit the desired 3D effect and eye movement effect.
  • the mat set 1241 in Fig. 46 also includes a top edge mat 1244 and a bottom edge mat 1246. These two edge mats can be mounted in a 3D frame of present invention in the same manner as the edge sheets 1214 and 1216 of Fig. 43 mounted in the frame body 1102 of Fig. 35.
  • the edge mats 1244 and 1246 are preferably cut from the same mat sheet from which the center mat 1242 is also cut. In this way, the two edge mats 1244 and 1246 will have the same color and texture as that of the center mat 1242. Once mounted, these two edge mats will blend nicely with the center mat to enhance the overall appearance of the 3D frame system.
  • Figs. 47-49 are preferably cut from the same mat sheet from which the center mat 1242 is also cut. In this way, the two edge mats 1244 and 1246 will have the same color and texture as that of the center mat 1242. Once mounted, these two edge mats will blend nicely with the center mat to enhance the overall appearance of the 3D frame system.
  • One of the major features in the 3D frame of the present invention is the creation of 3D space in the shape of an arch.
  • a three dimensional article such as reinforced pictures 1164 and 1174 and figurines 1166 can be magnetically held in this 3D space and be displayed.
  • this section several other novel means for holding three dimensional articles of various kind in this 3D space will be disclosed.
  • Fig. 47 discloses a novel 3D frame system 1250 which is basically the same as the 3D frame system 1 100 in Fig. 35 except with some changes for the purpose of holding a three dimensional article.
  • This 3D frame system 1250 comprises a frame body 1252, flat glass 1254 and pre-curved backing plate 1256, very much like the frame body 1102, first transparent plate 1106 and backing plate 1110, respectively, in Fig. 35.
  • a pre-curved mat plate 1258 is also seen in Fig. 47.
  • This mat plate 1258 has a center opening 1260 similar to the center mat 1242 shown in Fig. 46. But there are two important differences separating the mat plate 1258 and the center mat 1242.
  • the mat plate 1258 is typically made of plastics such as Acrylic which can be pre-curved by thermal forming process.
  • the center mat 1242 is cut from conventional paper mat which can not be pre- curved easily.

  • a three dimensional article which in this case is a lead glass angel 1262 mounted on a blue paper sheet 1264. Since the blue paper sheet 1264 is pressed between the pre-curved mat plate 1258 and the pre-curved backing plate 1256, it will also be curved and form a curvature same as that of the mat plate 1258.
  • the mounted lead glass angel 1262 because of its physical dimension, will clear and extend beyond the center opening 1260 toward the frame window of the frame body 1252.

  • the depth of the relief art or objects must not exceed that of the created 3D space.
  • fabric arts generally refer to any arts employing fabric sheet as its substrate or supporting sheet. This may include commonly known oil or Acrylic paintings on canvas, and cross stitching, needlepoint, or embroidery on cotton or synthetic fabric sheets.
  • Fig. 48 discloses one novel means for supporting and displaying such fabric arts in the 3D frame of the present invention.

  • the adhesive may include a foam layer which adds some softness to the contact and helps smooth out some unevenness typically found on the back side of the cross stitching art sheet 1270.
  • One major advantage in the use of the pre-curved backing plate 1272 with double sided adhesive 1274 is to ensure that the entire back surface of the soft fabric art 1270 is adhered to the backing plate 1272 and thus conformed to the curvature of the backing plate 1272. This is important for achieving the desired 3D effect and eye movement effect.
  • the fabric art 1270 Since the fabric art 1270 is closely adhered to the backing plate 1272, a well defined arch- shaped 3D space is created between the fabric art 1270 and the flat glass 1 106. This 3D space is especially desirable for some fabric arts such as ribbon embroidery which needs considerable amount of clearance in front of the art sheet.
  • the use of rubber based adhesive also has one advantage of allowing most fabrics to be removably adhered to the backing plate 1272. This is desirable during the initial mounting process for adjusting the positioning of the fabric art 1270. This fabric art 1270 can also be easily removed later from the backing plate 1272 when it is no longer needed for such display.
  • Fig. 49 shows a sheet of conventional mesh screen 1280 which is referred to as plastic canvas in the trade. It is made of soft plastics and may have ten or less mesh per inch (2.54 cm).

  • the mesh screen 1280 is a flat and flexible plastic sheet. It is possible with the present teaching, that a mesh screen made of hard plastics such as ABS can be molded with a predetermined curvature for the present application.

  • the arc length (AL) is related to the curvature radius according to the following equation.
  • the curvature radius (R) required for best 3D effect is generally smaller than that for eye movement effect. This means that for a given frame body width (W) the glass must be more curved for achieving desirable 3D effect than that for the eye movement effect.
  • the required curvature radius (R) for the pre-curved glass or backing plate is also 13" for achieving satisfactory 3D effect. Therefore, the required curvature radius (R) can be expressed as a function of the frame body width (W) as follow:
  • equations (1) and (5) only provide a guideline for the design of 3D frames in achieving satisfactory eye movement effect and 3D effect.
  • the exact choice of most suitable value of R must also be dependent on two other factors which are difficult to generalize.
  • the first factor of concern is the difference in perception of the eye movement effect and 3D effect by each individual viewer.

It is important that the anchoring ends of each Velcro ribbon be positioned as close as possible to the edge of the backing plate 1304 along its straight side. This will ensure that the strap 1308 will tightly wrap around the curved backing plate 1304 from edge to edge to securely fasten the stack to the 3D frame body 1306.

  • straps can also be adopted. This may include a conventional two-ring buckle that allows a ribbon to be locked between the two rings. Snap-on type buckle is also an acceptable choice.
  • the curved glass of the present invention is preferably made of Acrylic sheet which is available commercially in non-glare grade which would eliminate most glare in the present 3D frame system. At adequate thickness the Acrylic sheet can be heat treated to form a rigid curved glass for the present application. But for the sake of cost economy a thinner thickness at 0.060" (0.15 cm) or less is preferable. One other reason for this choice is that the formed Acrylic sheet is flexible which has some advantages as will be clear in the following discussion.
  • Fig. 52a shows the same curved glass 1290, picture sheet 1292, and backing plate 1294, rested on a 3D frame body 1320 whose width (W) is slightly wider than that of the 3D frame body 1296 of Fig. 50.
  • the curved glass is made of Acrylic sheet of 0.060" (0.15 cm) thick or less and is flexible.
  • the picture sheet 1292 is assumed to be flexible.
  • the backing plate 1294 can also be flexible if it is made of Acrylic sheet or other plastic material such as high impact polystyrene (HIPS) of thickness of 0.060" or less.
  • HIPS high impact polystyrene
  • An downward force applied by the strap will collapse the stack and cause it to spread out to fill the entire width of the 3D frame body 1320.
  • This is a convenient way to reduce the curvature of the curved glass 1290 and backing plate 1294.
  • Fig. 52b again shows the same stack of the curved glass 1290, picture sheet 1292, and backing plate 1294, resting on the same 3D frame 1296 of Fig. 50.
  • This figure also shows a cardboard strip 1310 inserted to each side of the stack. Since this stack is flexible as assumed before, it can be easily squeezed to reduce its width (W) and increase its curve height (CH). This is a convenient way to increase the eye movement effect or 3D effect on the displayed picture 1292.
  • a strap is not shown, but also can be included to hold down the stack and fasten it to the 3D frame body 1296.
  • a flat but flexible glass and backing plate can be bent to fit into a 3D frame body and fastened by a strap.
  • the pre-curved glass 1290 and pre- curved backing plate 1294 can be replaced by a normally flat but flexible glass and backing plate, both of which will be bent to fit into the 3D frame body 1320.
  • This approach is useful but is not recommended in general because such glass and backing plate are very likely out of round and may produce unpleasant distorted image.
  • this approach may become acceptable as the image distortion problem using 0.060" Acrylic sheet becomes less severe while the normal approach of making pre-curved glasses is getting more expensive.
  • Fig. 53 shows a fixture or preview frame 1340 which allows a picture to be viewed for its eye movement effect and /or 3D effect. It has a base plate 1342 shown with two grooves 1344 and 1346 with different curvatures. Two poles or threaded rods 1348 are mounted on the base plate 1342. Also shown in the figure is a top plate 1350 which has two holes for the poles to penetrate there through and for the top plate 1350 to slide along the poles 1348. Means such as nuts or clips, not shown, may also be included for holding the top plate 1350 at a desired height above the base plate. There are also two grooves 1352 and 1354 on the top plate which are mirror images of the two grooves 1344 and 1346, respectively, on the base plate.

  • the flat glass sheets 1392 and flat backing plates 1394 to be thermal formed must be cut to predetermined size for the 3D frame chosen. They are alternately loaded into the holder 1376 one sheet at a time. This will assure that each matching pair will have the same curvature and to avoid any miss match due to possible variation on the curvature from batch to batch. It is important that upon loading, each sheet must be individually pressed down and bent to a curvature similar to that of the concave mold 1374. The sheet will stay curved once the pressing hand is lifted. This is important since it would be very difficult to bend a large stack of flat sheets at a later time due to the friction between adjacent sheets. The side of each loaded sheet must be in touch with both the side plates 1378 and the sheet beneath it. The presence of gap between two adjacent sheets at either side indicates that the liner length of the sheet must be trimmed before further proceeding. On the other hand, the sheet with inadequate linear length will not stay curved

Abstract

La présente invention concerne un système de cadre (1100) destiné à maintenir une image normalement plate (1116) et la plie pour lui conférer une forme concavo-convexe unidimensionnelle ajoutant un effet tridimensionnel et/ou effet de mouvement de l'oeil. Pour obtenir cette forme concavo-convexe unidimensionnelle, on peut soit appliquer l'image (1116) contre une plaque transparente cintrée (1108), soit placer l'image (1116) sur un support cintré (1180). Un volume vide arciforme ménagé dans le système de cadre (1100) permet de loger un article tridimensionnel complémentaire (1166) et/ou une image cartonnée (1116) retenue par des éléments magnétiques (1112, 1114). Une vitre de bord supérieur (1208) et une vitre de bord inférieur (1210) sont placées dans le système de cadre perpendiculairement à la plaque transparente pré-incurvée (1206). Un bandeau image de bord supérieur (1214) et un bandeau image de bord inférieur (1216) peuvent être présentés à travers la vitre de bord supérieur (1208) et la vitre de bord inférieur (1210) de façon à compléter l'image principale (1204) présentée et donner à l'observateur l'impression de voir en tois dimensions l'image principale (1204). En outre, un dos d'image cintré (1110) pourvu d'un adhésif et un passe-partout cintré (1242) permettent de réserver un volume suffisant convenant à la présentation de textiles d'art, d'objets d'art en relief ou tout autre objet en volume dans ce système de cadre (1100).
