<1. Embodiment (configuration)>
An internally illuminated sign and receiving member according to an embodiment of the present invention will be described based on FIGS. 1 to 12. In the following, an internally illuminated sign 9 shown in FIG. 2 will be exemplified as an example of the internally illuminated sign according to the present invention. Further, an acrylic catcher 10 shown in FIG. 2 is illustrated as an example of a receiving member for an internally illuminated sign according to the present invention.

The internally illuminated sign 9 according to this embodiment has substantially the same configuration as the internally illuminated sign 8 shown in FIG. However, the internally illuminated sign 9 differs from the internally illuminated sign 8 shown in FIG. 1 in that the stainless steel plate 815 shown in FIG. 1 is not welded.

As shown in FIG. 2, the internally illuminated sign 9 includes a housing frame 91 having an opening on the front (top side in the drawing), an acrylic plate 93 that closes the front opening, and a structure for fixing the acrylic plate 93 to the housing frame 91. The push edge 95 and the acrylic catcher 10 are provided.

The housing frame 91 includes a back plate 911 that fixes an LED light (not shown), and a side plate 913 that extends from the back plate 911 toward the front opening.

A plurality of acrylic catchers 10 (an example of a receiving member for an internally illuminated sign according to the present invention) are mounted at intervals on the opening edge 913E of the side plate 913 on which the acrylic plates 93 are placed.

Hereinafter, the structure of the acrylic catcher 10 will be described in detail with reference to FIGS. 3 to 7.

As shown in FIGS. 3 to 5, the acrylic catcher 10 is a member made by bending ultra-thin stainless steel (specifically, SUS304), and has a first surface 1, a second surface 2, a third surface 3, and It is constructed with four sides (4 sides).

The first surface 1 is a plate-shaped member having a width W1 (FIG. 3) and extending in a direction D1.

The second surface 2 is bent at a substantially right angle to the first surface 1 from the end 1E (FIG. 5) in the direction D1 of the first surface 1, has a width W2 (FIGS. 3 and 4), and has a width W2 (FIGS. 3 and 4). It is a plate-shaped member that extends from .

The third surface 3 is bent at an acute angle with respect to the second surface 2 from an end 2E (FIG. 5) in the direction D2 of the second surface 2, and extends in the direction D3 with a width W3 (FIG. 7). However, the end portion 3E (FIG. 5) in the direction D3 is a member that comes into contact with the first surface 1.

The fourth surface 4 is a plate-shaped member that is bent from the end 3E (FIG. 5) of the third surface 3, has a width W4, and extends in the direction D4.

As shown in FIGS. 3 and 6, a welding hole 51 is formed in the center of the lower part of the first surface 1, and a welding hole 53 is formed in a portion bent from the end 1E to the second surface 2. Acrylic catcher 10 is welded to side plate 913 of housing frame 91 via welding hole 51 or welding hole 53.

By the way, as shown in FIG. 12, the acrylic catcher 10 may be attached to a portion of the side plate 913 that has a curved surface that is convex toward the side. In this case, if the width W1 of the first surface 1 is too wide, both ends in the direction of the width W1 may rise significantly from the outer peripheral surface of the side plate 913 and cannot be covered with the push edge 95.

On the other hand, in this embodiment, when the acrylic catcher 10 is attached to the part of the side plate that has the largest curve (smallest radius of curvature), the distance FL between both ends and the side plate 913 in the width W1 direction (FIG. 12 The length of the width W1 is set so that the width W1 is less than or equal to a predetermined tolerance value.

As shown in FIGS. 3 and 4, the width W2 of the second surface 2 is wider on the end 2E side than on the end 1E side. The width W2 and the length in the direction D2 of the second surface 2 are set to values that ensure an area and strength in which the acrylic plate 93 can be placed and do not block light from a light source (LED lighting) not shown. ing.

As shown in FIG. 5, the vicinity of the end of the second surface 2 opposite to the end 2E in the direction D2 (the part bent from the end 1E) has a concave shape when viewed from the inside (from the outside). A fitting groove portion 21 having a convex shape when seen is formed. The fitting groove 21 is configured to have a width that allows the opening edge 913E of the side plate 913 forming the housing frame 91 to fit therein. When the acrylic catcher 10 is attached to the side plate 913, the opening edge 913E of the side plate 913 fits into the fitting groove 21 of the second surface 2.

As shown in FIGS. 3 and 5, the third surface 3 is bent at about 45 degrees with respect to the second surface 2 and extends toward the first surface 1. Accordingly, when the acrylic catcher 10 is attached to the opening edge 913E of the side plate 913 constituting the housing frame 91, the third surface 3 is inclined with respect to the incident light from the light source (LED lighting). There is.

As shown in FIGS. 4 and 5, the fourth surface 4 is bent about 120 degrees with respect to the third surface 3 and extends in a direction away from the first surface 1. Along with this, the fourth surface 4 gradually separates from the first surface 1 as it moves toward the end 4E, and a gap SP (see FIG. 5) is formed between the fourth surface 4 and the first surface 1. .

Further, as shown in FIG. 5, the end 4E of the fourth surface 4 and the end 1F of the first surface 1 are arranged at different positions with respect to the direction D1. That is, a step UE is formed between the first surface 1 and the fourth surface 4 in the direction D1. Note that the end 4E is one end of both ends of the fourth surface 4 in the direction D4, and the end 1F is the end opposite to the end 1E of the first surface 1 in the direction D1. .

As shown in FIGS. 4 and 7, openings 55 (elongated holes) are formed in the third surface 3 and the fourth surface 4 so as to straddle both surfaces in order to reduce the reflective area. The aperture 55 is an example of an aperture for preventing diffuse reflection according to the present invention.

Note that the acrylic catcher 10 according to the present embodiment is also referred to as a clip because the side plate 913 of the housing frame 91 is held between the first surface 1 and the end portion 3E of the third surface 3.

<2. Embodiment (assembly method)>
Next, a method for assembling the internally illuminated sign 9 using the acrylic catcher 10 described above will be described in detail with reference to FIGS. 8 to 11.

First, as shown in FIG. 2, the housing frame 91 is placed on the placement surface with the back plate 911 disposed on the lower side (on the placement surface side) and the front opening facing upward.

Next, the opening edge 913E of the side plate 913 is placed between the first surface 1 and the fourth surface 4 (gap SP) of the acrylic catcher 10, and the acrylic catcher 10 is pushed downward. Accordingly, as shown in FIG. 8, the opening edge 913E of the side plate 913 is inserted between the first surface 1 and the end 3E of the third surface 3. At this time, the ends 3E of the first surface 1 and the third surface 3 repel the elastic force of the acrylic catcher 10 and separate.

After this, when the acrylic catcher 10 is pushed further downward, the opening edge 913E of the side plate 913 will eventually fit into the fitting groove 21 formed on the second surface 2, as shown in FIG. match.

As shown in FIG. 9, when the acrylic catcher 10 is attached to the opening edge 913E of the side plate 913, the first surface 1 is placed in contact with the outside of the side plate 913 so as to be parallel to the side plate 913. be done. On the other hand, the end 3E of the third surface 3 is placed in contact with the inside of the side plate 913. Moreover, the opening edge 913E of the side plate 913 comes into contact with the fitting groove 21 of the second surface 2.

Note that, as shown in FIG. 2, a plurality of acrylic catchers 10 are attached to the opening edge 913E of the side plate 913 that constitutes the housing frame 91.

After attaching the plurality of acrylic catchers 10 to the opening edge 913E of the side plate 913, as shown in FIG. The front opening of the body frame 91 is closed.

Thereafter, as shown in FIG. 11, a push edge 95 is provided on the acrylic plate 93 with the front opening of the housing frame 91 closed, and the acrylic plate 93 is fixed to the housing frame 91.

Through the above procedure, the internally illuminated sign 9 is assembled using the acrylic catcher 10.

<3. Embodiment (effect)>
According to the embodiment described above, the receiving member for the acrylic plate 93 can be installed by an extremely simple method such as inserting a plurality of acrylic catchers 10 into the opening edge 913E of the side plate 913 of the housing frame 91 at predetermined intervals. The working time required to manufacture the illuminated sign 9 can be significantly reduced.

In particular, the acrylic catcher 10 according to this embodiment has high versatility because it does not depend on the shape of the side plate 913 of the housing frame 91 and can be used for housing frames of other shapes.

Further, according to the embodiment described above, since stainless steel (SUS304) is used as the material for the acrylic catcher 10, sufficient corrosion resistance outdoors is ensured, and sufficient space is required to place the acrylic plate 93. Strength is ensured.

In particular, according to the embodiment described above, since extremely thin stainless steel is used, the acrylic catcher 10 attached to the opening edge 913E of the side plate 913 does not get in the way when the push edge 95 is covered.

Further, according to the embodiment described above, as shown in FIG. No need to fall to the side.

Further, according to the embodiment described above, as shown in FIG. When attaching to the side plate 913, the opening edge 913E of the side plate 913 can be easily inserted and can be attached with one touch.

Further, according to the embodiment described above, since the third surface 3 is inclined with respect to the incident light from the light source (LED lighting), the reflected light of the incident light is difficult to reach the acrylic plate 93.

Further, according to the embodiment described above, since the openings 55 are formed in the third surface 3 and the fourth surface 4, the reflection area of light from the light source is reduced, and diffuse reflection does not occur inside the housing frame 91. , light unevenness is less likely to occur on the acrylic plate 93.

Further, according to the embodiment described above, since the acrylic catcher 10 is welded to the side plate 913 of the housing frame 91 via the welding hole 51 or the welding hole 53, the acrylic catcher 10 is unlikely to fall off.

Further, according to the embodiment described above, since the acrylic plate 93 is covered with the push edge 95, the acrylic catcher 10 does not need to be projected onto the acrylic plate 93.

Further, according to the embodiment described above, the side plate 913 of the housing frame 91 is sandwiched between the first surface 1 and the end portion 3E of the third surface 3, and the elastic force of the acrylic catcher 10 is applied to the sandwiched portion. Therefore, the acrylic catcher 10 is difficult to come off.

Next, the cost reduction rate when using the acrylic catcher 10 will be explained.

The inventors of the present application compared and verified the cost when the acrylic catcher 10 according to the present embodiment is used as a receiving member and the cost when the stainless steel plate 815 (see FIG. 1) is used as a receiving member.

As a result, the cost reduction rate for "500 x 500 normal kanji" was 18.27%, and the cost reduction rate for "1000 x 1000 normal kanji" was 19.02%. Therefore, regardless of the size of the internally illuminated sign, both are less costly than the prior art.

Furthermore, the cost reduction rate for "500 x 500 Kana Kaku Gothic" was 15.89%, and the cost reduction rate for "1000 x 1000 Kana Kaku Gothic" was 17.76%. Therefore, regardless of the size of the internally illuminated sign, both are less costly than the prior art.

Furthermore, when comparing "500 x 500 normal kanji" and "1000 x 1000 normal kanji", the cost reduction rate of the internally illuminated sign with the larger size "1000 x 1000 normal kanji" is higher. Also, when comparing "500 x 500 Kana Kaku Gothic" and "1000 x 1000 Kana Kaku Gothic", the cost reduction rate of the larger "1000 x 1000 Kana Kaku Gothic" internally illuminated sign is also higher. There is. That is, it can be seen that the acrylic catcher 10 according to this embodiment has a particularly high cost reduction effect when manufacturing a large-sized internally illuminated sign.

<4. Modified example>

For example, in the embodiment described above, as shown in FIG. However, it is not limited to this. As shown in FIG. 13, the acrylic catcher 10 may be configured with three surfaces: a first surface 1, a second surface 2, and a third surface 3. According to this configuration, since the fourth surface 4 no longer exists, the acrylic catcher 10 cannot be attached with one touch. , it is possible to significantly reduce the working time.

Further, in the above-described embodiment, the welding holes 51 and 53 are formed in two places, but the present invention is not limited to this, and only one of the welding holes 51 and 53 is formed. Good too.

Further, in the above-described embodiment, the case where the acrylic plate 93 formed of acrylic resin (PMMA) is used as the transmission plate is illustrated, but the present invention is not limited to this, and a polycarbonate plate formed of polycarbonate resin (PC) is used as the transmission plate. It may also be used as a board.

Further, in the above-described embodiment, the case where the third surface 3 is bent at about 45 degrees with respect to the second surface 2 is illustrated, but the angle of the third surface 3 with respect to the second surface 2 is not limited to this. may be changed as appropriate so long as the reflected light from the LED lighting does not reach the acrylic plate 93.
Further, in the embodiment described above, the case where the end portion 3E (FIG. 5) of the third surface 3 comes into contact with the first surface 1 is illustrated, but the present invention is not limited to this. For example, if the distance between the end 3E and the first surface 1 is shorter (narrower) than or the same as the thickness of the side plate 913, it is not necessary that they come into contact with each other, and the end 3E and the first surface 1 may be close to each other. It may be configured as follows.

As described above, the receiving member for an internally illuminated sign according to the present invention is suitable for mounting a transparent plate fixed to the housing frame of an internally illuminated sign.
