Description

  The present invention relates to a picture frame. More specifically, it relates to a picture frame that displays light on paintings, photographs, posters, award certificates, jigsaw puzzles, and other viewing objects.

  A picture frame is a frame for inserting pictures, photographs, posters, award certificates, jigsaw puzzles, and the like. Frames include oil paintings, photo frames, poster panels, and prize certificates, depending on the application. The frame is formed of various materials such as wood, metal, glass, ceramics, plastic, plaster, and lacquer, and is used for various purposes such as decorating and protecting ornaments to be put inside. Light is often applied to decorative objects placed in the frame to enhance the viewing effect. For example, a picture or a jigsaw puzzle placed in a frame can be illuminated with external lighting such as a spotlight attached to the outside to make the viewing effect stand out.

  However, in recent years, there has been a combination of a frame and a lighting device that are integrated without separately providing a frame and external illumination. For example, there is a frame in which a fluorescent lamp, a cold cathode tube, a surface light emitting device, and the like are incorporated on the back side of an appreciation object. There is also a frame called a light panel with a light guide plate inside the frame that decorates the poster. As described above, various lighting fixtures are attached to the frame, and there are various methods for shining light on the appreciation object. Conventional techniques will be described based on patent documents.

  For example, there is known a frame that can be illuminated from the front, is small in size, generates little heat, and has an illumination function with little uneven illumination (see Patent Document 1). There is also known a surface light emitting device in which light from a light source is effectively used to brighten a light emitting surface, and the brightness of the entire light emitting surface tends to be uniform regardless of the distance from the light source. (See Patent Document 2). Furthermore, a novel edge light panel that is extremely unique and interesting is said to have an illuminating effect that is raised on the surface of the panel and its four peripheral edges (see Patent Document 3). .

JP 2006-187400 A JP 2004-85677 A JP 2011-95439 A

  The frame described in Patent Document 1 is illuminated uniformly from the back side of the photographic film by turning on a light emitting diode as an illumination means. However, there was a problem that the front side of the photographic film could not be illuminated. In the surface light emitting device described in Patent Document 2, the brightness of the entire light emitting surface is uniform regardless of the distance from the light source. However, there is a problem that the structure is complicated because at least the plate-like light emitting surface, the irregular reflection surface, and the reflection surface must be provided.

  The edge light panel described in Patent Document 3 is radiated as if fringing the four peripheral edges of the panel substrate in addition to the translucent illumination for the translucent display sheet portion. However, there is a problem that the structure is complicated because at least a transparent material panel substrate, a light guide reflection plate, and a transparent material front plate must be provided. In other words, the traditional frame often shines light from the back of the appreciation object, and it only illuminates the appreciation with light leaking from between the frame of the frame and the appreciation object, and the light is the entire appreciation object. There was a problem that it was not possible to illuminate evenly. In addition, the conventional frame has a problem in that it has a complicated structure and a large number of parts, and many of them are troublesome to assemble.

[Embodiment 1 of the present invention]
Hereinafter, the frame 1 of the present invention will be described in detail as a first embodiment of the present invention based on the drawings. FIG. 1 is an external view of a frame 1 to which Embodiment 1 of the present invention is applied. FIG. 2 is an external view showing a state in which the frame 1 is disassembled. FIG. 3 is a rear view of the frame 10. FIG. 4 is an external view showing a state of the substrate 21 attached to the upper frame 11 by breaking the R1 portion of FIG. FIG. 5 is a partial cross-sectional view showing the state of FIG. 1 cut along the α-α line.

  As shown in FIG. 1, description will be made with the arrow F direction as the forward direction and the reverse direction of the arrow B as the backward direction. In the description, the arrow L direction, which is one direction orthogonal to the front-rear direction in the horizontal plane, is the left direction, and the arrow R direction, which is another direction orthogonal to the right direction, is the right direction. The description will be made with the arrow U direction, which is the upper direction orthogonal to the front-rear direction and the left-right direction, being the upward direction and the arrow D direction being the lower direction being the downward direction. Further, the front side (arrow F direction) side of the light guide plate 30, the photograph A1, and the back plate 50 will be described as the front side, and the reverse side (arrow B direction) side will be described as the reverse side.

[Frame 1]
As shown in FIG. 1, the frame 1 according to the first embodiment is a photo frame for displaying a photo A1 as an appreciation object. As shown in FIGS. 2 to 4, the frame 1 includes a frame 10, an LED 20, a light guide plate 30, a back plate 50, and a fastener 70. The frame 1 is used by assembling a photograph A1 between the light guide plate 30 and the back plate 50 as shown in FIG. 2 and decorating it at a predetermined place as shown in FIG. As shown in FIGS. 1 and 2, in this example, a flower is shown in the photograph A1.

[Frame 10]
The frame 10 is a framework for storing and supporting the photograph A1, and is composed of an upper frame 11, a lower frame 12, a right frame 13, and a left frame 14, as shown in FIGS. The upper frame 11 is formed in an elongated trapezoidal shape as shown in FIG. 3, and is formed in a substantially J shape when viewed from a cross section as shown in FIG. As shown in FIG. 3, the lower frame 12 is formed in an elongated trapezoidal shape, and as shown in FIG. As shown in FIG. 3, the right frame 13 and the left frame 14 are also formed in an elongated trapezoidal shape, and although not shown, they are formed in an approximately L shape when viewed from a cross section. When the upper frame 11, the lower frame 12, the right frame 13, and the left frame 14 are combined, a rectangular frame 10 as shown in FIG. 3 is formed, and a rectangular opening 10h is formed.

  The opening 10h has an inner shape smaller than the outer size of the photograph A1. For example, the inner shape of the opening 10h is formed so that the width is 84 mm and the height is 122 mm in this example. As shown in FIGS. 3 and 4, the upper frame 11 is formed with an upper frame placement portion 11 c that is a plane on which the light guide plate 30, the photograph A <b> 1, and the back plate 50 are placed. The upper frame placement portion 11c is a step formed on the opening 10h side of the upper frame 11 as shown in FIG. 3 and lower from the back side to the front side as shown in FIGS.

  As shown in FIG. 3, the lower frame 12, the right frame 13, and the left frame 14 also have a flat lower frame placement portion 12 c, right frame placement portion 13 c, and left frame on the opening 10 h side, similarly to the upper frame 11. A frame placing portion 14c is formed. The frame 10 is formed by combining an upper frame placing part 11c, a lower frame placing part 12c, a right frame placing part 13c, and a left frame placing part 14c. The placement portion 10c is formed so that its inner shape dimension is the same as or slightly larger than the outer dimension of the photograph A1. For example, the mounting portion 10c is formed with an inner dimension such that the width is 89 mm and the height is 127 mm.

  As shown in FIG. 3, two fasteners 70 are attached to the upper frame 11. The fastener 70 is a component for fixing the light guide plate 30, the photograph A <b> 1, and the back plate 50 to the upper frame 11. The fastener 70 is fixed to the upper frame 11 by screwing, for example, and the light guide plate 30, the photograph A1, and the back plate 50 can be attached and detached by rotating. Similarly, two fasteners 70 are attached to the lower frame 12, the right frame 13, and the left frame 14, respectively.

  As shown in FIG. 4, the upper frame 11 is formed with a light source storage portion 11 r for storing the substrate 21. As shown in FIG. 3, the light source storage portion 11r is formed in an elongated rectangular shape from one end to the other end of the upper frame 11, and is formed adjacent to the upper frame placement portion 11c as shown in FIG. It is a groove. As shown in FIGS. 3 and 4, a substrate 21 is accommodated in the light source accommodating portion 11r.

[LED20]
The LED 20 is a light source for causing the light guide plate 30 to emit light. As shown in FIG. 3, 16 LEDs 20 are attached to a substrate 21 formed in an elongated plate shape at a predetermined interval. As shown in FIG. 4, the LED 20 is installed so as to face downward (arrow D direction), and as shown in FIG. 5, the LED 20 faces the upper side (arrow U direction) side of the light guide plate 30. It is installed on the substrate 21. As shown in FIG. 5, the substrate 21 is installed along the side surface on the upper direction (arrow U direction) side of the light guide plate 30.

  Although not specifically shown, the substrate 21 is connected to a power supply line, and the LED 20 emits light when power is supplied. The power may be supplied from an external power source such as a power outlet by connecting a power plug to the power line, or may be supplied by connecting a battery to the power line. Although not particularly illustrated, a main power button for switching on / off of current is attached to the power line. In this example, the board | substrate 21 is attached to the upper frame 11 installed in the upper direction (arrow U direction) side in order to form the light pool G mentioned later. However, if it is not necessary to form the light reservoir G (see FIG. 1), the substrate 21 may be attached to the lower frame 12, the right frame 13, and the left frame 14 other than the upper frame 11.

[Light guide plate 30]
The light guide plate 30 is a sheet for irradiating the light emitted from the LED 20 installed on the side surface to the photograph A1 side. As shown in FIG. 2, the light guide plate 30 is installed so as to cover the surface side of the photograph A1. The light guide plate 30 is formed to have the same outer dimensions as the photograph A1. In this example, the light guide plate 30 is a substantially rectangular flat plate having a width of about 89 mm and a height of 127 mm. The light guide plate 30 is formed by injection molding, and is entirely or partially formed of a transparent or translucent acrylic resin that transmits light. On the surface of the light guide plate 30, a dot pattern 40 for forming the light guide plate 30 into a planar light source is formed.

[Dot pattern 40]
The dot pattern 40 is a reflecting member for reflecting the light emitted from the LED 20 to turn the light guide plate 30 into a planar light source. As shown in FIGS. 6 and 7, in this example, the dot pattern 40 is formed integrally with the light guide plate 30 manufactured by injection molding. The dot pattern 40 is formed by a collection of fine semispherical lenses formed so as to protrude forward (arrow F direction) from the surface of the light guide plate 30. For example, as shown in FIG. 6, the dot pattern 40 is installed so as to be sparse in the vicinity of the LED 20.

  Further, as shown in FIG. 7, the dot pattern 40 is disposed so as to be dense in a portion away from the LED 20. Similar to the light guide plate 30, the dot pattern 40 is formed of a transparent or translucent acrylic resin that is partially or entirely transmissive to light. Since the dot pattern 40 is installed in this way, light efficiently and uniformly spreads over the light guide plate 30, and the light guide plate 30 becomes a flat light source. For example, the diameter of the lens installed on the light guide plate 30 may be reduced in a portion close to the LED 20 and increased in a portion away from the LED 20.

[Back plate 50]
The back plate 50 is a wooden flat plate for pressing the photograph A1 from the back side. As shown in FIG. 2, the back plate 50 is installed so as to cover the back side of the photograph A1. The back plate 50 is formed to have the same outer dimensions as the photograph A1, and has a width of about 89 mm and a height of 127 mm. A support plate 60 is attached to the back plate 50 so that the frame 1 can be stood up and decorated.

[How to use frame 1]
Next, a method of using the frame 1 will be described with reference to FIGS. FIG. 6 is a partially enlarged cross-sectional view in which the portion R2 in FIG. 5 is enlarged, and is an explanatory diagram depicting a trajectory of light that moves through the frame 1. FIG. 7 is a partially enlarged cross-sectional view in which the portion R3 in FIG. 5 is enlarged, and is an explanatory diagram schematically illustrating a trajectory of light moving through the frame 1.

  The frame 1 is placed and decorated on a flat placement surface (for example, a desk or the like) as shown in FIG. In the frame 1, when the main power button is turned on, power is supplied to the LED 20 and the LED 20 emits light (not shown). As shown in FIGS. 6 and 7, the light incident from one side surface of the light guide plate 30 travels to the front side and the back side inside the light guide plate 30. The light directed toward the back side of the light guide plate 30 irradiates the photograph A1. The light directed toward the front surface side of the light guide plate 30 is diffusely reflected by the dot pattern 40 and radiates the photograph A1 toward the back surface side of the light guide plate 30. Further, the light leaking through the dot pattern 40 and leaking from the light guide plate 30 forms a light pool G on the placement surface in front of the frame 1 as shown in FIG.

  As shown in FIGS. 5 and 6, the dot pattern 40 is installed so as to be sparse in the portion close to the LED 20. As shown in FIGS. 5 and 7, the dot pattern 40 is disposed so as to be dense in a portion away from the LED 20. The back surface of the light guide plate 30 is irradiated with uniform light even in the vicinity of the LED 20 that is the light source or in a portion away from the LED 20. Thus, since the back surface of the light guide plate 30 emits uniform surface light without uneven brightness, the entire surface of the photograph A1 is irradiated with light evenly. The photograph A1 looks as if the photograph A1 itself is emitting light. The frame 1 has a simple configuration, a small number of parts, and is easy to assemble.

[Embodiment 2 of the present invention]
Next, a second embodiment of the present invention will be described in detail based on the drawings. Note that the frame 101 of the second embodiment has substantially the same configuration as the frame 1 of the first embodiment described above, and only a different configuration will be described. FIG. 8 is a diagram illustrating a state in which the frame 101 according to the second embodiment of the present invention is disassembled, and is an external view corresponding to FIG. 2 according to the first embodiment. FIG. 9 is a partial cross-sectional view of the frame 101 and is a cross-sectional view corresponding to FIG. 5 of the first embodiment. FIG. 10 is a partially enlarged cross-sectional view in which the portion R4 in FIG. 9 is enlarged, and is an explanatory diagram depicting the trajectory of light moving through the frame 101. FIG. 11 is a partially enlarged cross-sectional view in which the portion R5 in FIG. 9 is enlarged, and is an explanatory diagram schematically illustrating the trajectory of light moving through the frame 101. FIG. FIG. 12 is an external view of a frame 101 to which the second embodiment of the present invention is applied.

[Jigsaw Puzzle A2]
First, the frame 101 is different from the frame 1 in that the object to be displayed and decorated is a jigsaw puzzle A2 made of a transparent or translucent synthetic resin that transmits light. As shown in FIGS. 8 and 9, in this example, butterflies and flowers are printed on the combined jigsaw puzzle A2. Although not shown, the jigsaw puzzle A2 is formed in a laminated structure in which one soft sheet made of a transparent material is sandwiched between two hard sheets made of a transparent material. The hard sheet is formed of polypropylene, and the soft sheet is formed of polypropylene as a main component and an olefin type thermoplastic elastomer as a sub component.

  The hard sheet may be other than polypropylene, for example, one or more thermoplastic synthetic resins selected from polyvinyl chloride, polyethylene, polystyrene, and polyethylene terephthalate. The main component of the flexible sheet may be other than polypropylene, or one or more thermoplastic synthetic resins selected from polyvinyl chloride, polyethylene, polystyrene, and polyethylene terephthalate. Further, the secondary component of the soft sheet may be other than the olefin-based thermoplastic elastomer, or may be one or more thermoplastic elastomers selected from styrene-based thermoplastic elastomers and polyester-based thermoplastic elastomers.

[Light guide plate 130]
As shown in FIGS. 10 and 11, the frame 101 is different from the frame 1 in the position and orientation in which the light guide plate 130 is attached. As shown in FIG. 8, the light guide plate 130 is installed so as to cover the back side of the jigsaw puzzle A2. The dot pattern 140 is formed by a collection of fine lenses formed so as to protrude rearward (arrow B direction) from the back surface of the light guide plate 130. Similar to the light guide plate 30, the light guide plate 130 is entirely or partially formed of a transparent or translucent acrylic resin that transmits light. The light guide plate 130 may be used with the light guide plate 30 of the first embodiment turned upside down.

[Front plate 150]
Furthermore, the frame 101 is different from the frame 1 in that the back plate 50 is not used and a transparent or translucent front plate 150 that transmits light entirely or partially is used. The front plate 150 is a synthetic resin flat plate for holding the jigsaw puzzle A2 from the front. As shown in FIG. 8, the front plate 150 is installed so as to cover the surface side of the jigsaw puzzle A2. The front plate 150 is a transparent or translucent acrylic flat plate that transmits light entirely or partially. As shown in FIG. 8, the front plate 150 is formed to have the same outer dimensions as the jigsaw puzzle A2.

[How to use frame 101]
Next, a method for using the frame 101 will be described with reference to FIGS. Unlike the frame 1, the frame 101 is hung on a wall or the like and decorated. As shown in FIGS. 8 and 9, the front plate 150, the jigsaw puzzle A <b> 2, and the light guide plate 130 are stacked and placed on the frame 10 in this order. In the frame 1, when the main power button is turned on, power is supplied to the LED 120, and the LED 120 emits light (not shown).

  As shown in FIGS. 10 and 11, light incident from one side surface of the light guide plate 130 travels to the front side and the back side inside the light guide plate 130. Light directed toward the surface side of the light guide plate 130 irradiates the jigsaw puzzle A2. The light traveling toward the back surface side of the light guide plate 130 is diffusely reflected by the dot pattern 140 and radiates toward the front surface side of the light guide plate 130 with the jigsaw puzzle A2.

  As shown in FIGS. 9 and 10, the dot pattern 140 is installed so as to be sparse in a portion close to the LED 120. As shown in FIGS. 9 and 11, the dot pattern 140 is disposed so as to be dense in a portion away from the LED 120. The surface of the light guide plate 130 is irradiated with uniform light even at a portion close to or away from the LED 120 that is a light source. In this way, the surface of the light guide plate 130 emits uniform surface light without uneven brightness, so that the jigsaw puzzle A2 is evenly irradiated with light over the entire back surface.

  The light guide plate 130 irradiates the back surface of the jigsaw puzzle A2 with light from various angles. Thus, since the jigsaw puzzle A2 is irradiated with light from various angles, as shown in FIG. That is, although the picture frame 101 is decorated with the jigsaw puzzle A2, it looks as if it is decorated with stained glass. The light emitted from the light guide plate 130 passes through the jigsaw puzzle A2 and the front plate 150. For this reason, the entire frame 101 including the jigsaw puzzle A2 appears to shine.

[Embodiment 3 of the present invention]
Next, a third embodiment of the present invention will be described in detail based on the drawings. Note that the frame 201 of the third embodiment has substantially the same configuration as the frame 1 of the first embodiment described above, and only a different configuration will be described. Further, since the jigsaw puzzle A3 and the front plate 250 of the third embodiment are substantially the same as the jigsaw puzzle A2 and the front plate 150 of the second embodiment, detailed description thereof is omitted. 13 is a partial cross-sectional view of the frame 201 and is a cross-sectional view corresponding to FIG. 5 of the first embodiment. FIG. 14 is a partially enlarged cross-sectional view in which the portion R6 in FIG.

  As shown in FIG. 14, the frame 201 differs from the frame 1 in the position and orientation in which the light guide plate 230 is attached, and the structure of the dot pattern 240 is different. The light guide plate 230 is formed of a transparent or translucent acrylic resin that transmits light entirely or partially. As shown in FIGS. 13 and 14, the light guide plate 230 is installed so as to cover the back side of the jigsaw puzzle A3. Similar to the dot pattern 40 and the dot pattern 140, the dot pattern 240 is a reflecting member that reflects the light emitted from the LED 220 and converts the light guide plate 230 into a planar light source.

  The dot pattern 240 is formed by a collection of fine cylindrical dots printed on the surface of the light guide plate 230. The dot pattern 240 is formed so as to protrude rearward (in the direction of arrow B) from the back surface of the light guide plate 230. The dot pattern 240 is formed by printing white ink on the light guide plate 230 by a silk screen method. In addition, the dot pattern 240 may be installed so as to be sparse in the vicinity of the LED 220 as in the dot pattern 40 of the first embodiment.

  Moreover, the dot pattern 240 may be installed so as to be dense in a portion away from the LED 220 as in the dot pattern 40 of the first embodiment. The light guide plate 230 may be turned over so that the dot pattern 240 faces forward (arrow F direction). In this example, the dot pattern 240 prints white ink on the light guide plate 230 by a silk screen printing method. However, you may print by other printing methods, such as offset printing, gravure printing, letterpress printing, flexographic printing, and screen printing.

  The manner in which the surface of the light guide plate 230 emits surface light is substantially the same as the manner in which the light guide plate 130 of the second embodiment emits surface light, and thus detailed description thereof is omitted. Note that when the light guide plate 230 causes the LED 220 to emit light and emits light, the dot pattern 240 cannot be seen due to its brightness. A dot pattern 240 is printed on the light guide plate 230 of the third embodiment by silk screen printing. On the other hand, the dot patterns 40 and 140 are integrally formed by injection molding on the light guide plates 30 and 130 of the first and second embodiments. That is, the light guide plate 230 formed by printing can be manufactured at a lower cost than the light guide plates 30 and 130 formed by injection molding.

[Embodiment 4 of the present invention]
Next, a fourth embodiment of the present invention will be described in detail based on the drawings. The frame 201 of the fourth embodiment is different only in that the covering member 280 is used for the frame 201 of the third embodiment described above, and only that portion will be described. FIG. 15 is a partially enlarged cross-sectional view illustrating a state in which the covering member 280 is installed on the surface side of the light guide plate 230. The covering member 280 is a member for hiding the dot pattern 240 of the light guide plate 230.

  In this example, the covering member 280 is formed of white translucent paper and is formed to have the same outer dimensions as the light guide plate 230. As shown in FIG. 15, the covering member 280 hides the dot pattern 240 while being sandwiched between the jigsaw puzzle A <b> 3 and the light guide plate 230. Thus, by using the covering member 280, the dot pattern 240 is not visible even when the LED 220 is turned off and the light guide plate 230 is turned off.

  While various embodiments of the present invention have been described above, the present invention is not limited to these embodiments. Needless to say, changes can be made without departing from the scope and spirit of the present invention. In this example, the frame 1, 101, 201 has been described with a so-called photo frame and jigsaw puzzle panel. However, it goes without saying that other objects may be included. For example, it may be an oil painting amount, a temporary margin, a drawing amount, a sum, a colored paper amount, a strip amount, a certificate amount, a certificate amount, a medal amount, a prize amount, an insignia amount, a poster panel and a towel amount. Needless to say, the configuration of the present invention may be used for a mirror, a clock, a photo frame, or the like.

  Although the frame 10 has been described as being made of wood, other members may be used. For example, extruded aluminum may be used. As the light source, the LED 20, 120, 220 which is a point light source is used, but not limited to the point light source, a linear light source such as a cold cathode tube may be used as the light source. The dot patterns 40, 140, and 240 are formed integrally with the light guide plates 30 and 130, but may be formed by other methods. For example, the light guide plates 30, 130, and 230 may be formed with unevenness by a stamper or injection.

  The shape of the dot patterns 40, 140, and 240 is not limited to a convex lens shape or a cylindrical shape, and may be, for example, a circle, an ellipse, a rectangle, a triangle, a polygon, or the like. That is, the dot patterns 40, 140, and 240 may have any shape as long as they can be guided to the light emitting surface by moving inside the light guide plates 30, 130, and 230. The dot pattern 240 is printed with white ink by a silk screen method, but other colors may be used. The covering member 280 is made of translucent paper, but may be another member such as a translucent film as long as the dot pattern 240 can be hidden. Further, although the covering member 280 uses white translucent paper in accordance with the white color of the dot pattern 240, other translucent paper may be used.
