  The “internal lighting signboard” described in these Patent Documents 1 to 5 is considered to be able to exert an effect according to its purpose, but in the “signboard” of these patent documents, I don't care about mass production. In other words, this type of internally illuminated signboard usually varies in size depending on the purpose of use and installation location, but the inventors of Patent Documents 1 to 5 should be capable of mass production. It is thought that there is no will.

  In general, this type of internally illuminated signboard is described in paragraph 0005 of Patent Document 5, "In the conventional signboard manufacturing method, the installation work at the site may directly serve as the signboard manufacturing process. In most cases, it took a lot of labor and time to manufacture signboards, so even in the manufacture of signboards of the same size, it was always a single product, which was extremely low in productivity and required considerable skill. To do ".

  In addition, this type of internally illuminated signboard is usually constructed on the premise that a signboard is attached in advance in a building such as a normal building, as described in paragraph 0006 of Patent Document 5. `` The inconvenience of having to proceed with the construction process of the building to which the signboard is attached, and the installation of the signboard in a retrofitted form after the construction of the building, etc. were particularly troublesome work. '' Is.

  Therefore, in the internally illuminated signboard described in Patent Document 5, a “drawer” as shown in FIG. 13 is used to form a frame as shown in FIG. It is as shown in FIG.

  That is, in the signboard of this Patent Document 5, the drawing material as shown in FIG. 13 is cut into the size of the signboard to be formed into four sapwoods, and these four sapwood frames are shown in FIG. Since the frame is combined in a shape, the dimensions of the construction site must be accurately measured before the signboard is installed, and the dimensions cannot be adjusted on site.

  The use of the “drawing material” in Patent Document 5 can be applied to mass production for forming each side material of the signboard, but the exact dimensions must be determined when forming the signboard. If the measurement is a little wrong, it must be re-produced, and it is never considered that the workability is good.

  Therefore, the present inventors are able to simplify the production and construction of the size according to the order for this type of internally illuminated signboard, and how to make it possible to mass-produce in advance. As a result of various studies, the present invention has been completed.

  That is, an object of the present invention is to provide an internally illuminated signboard that can be produced and constructed in a size corresponding to an order in a short time and easily, and most of which can be mass-produced in advance. It is in.

In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the best mode described below.
“Internal light source 30, display material 20 capable of floating characters and designs by transmitting light from internal light source 30, and at least one of the side surfaces of the display material 20 fixed to form a side surface An internally illuminated signboard 100 having two frame bodies 10,
The frame body 10 is constituted by a side frame 11 having a “U” shape in plan view, and two long side frames 12 that connect the connecting ends of the side frames 11, and these sides. The frame body 11 and the long side frame body 12 are formed by the same drawing material having the connecting material insertion hole 13a,
The first connecting member 13 is positioned in the connecting insertion hole 13a opened at the connecting end portion of the both side frame body 11 and the long side frame body 12, and the center portion thereof is positioned between the both side frame body 11 and the long side frame body 12. In addition, the first connecting member 13 is used to connect the side frames 11 and the long-side frame 12 to each other.
It is.

  In the above and the following, “plan view” refers to a case where the frame main body 10 is seen in a state as shown in FIG. 2 and is adapted to the installation state of the internally illuminated signboard 100 itself. It is not a state.

  As shown in FIG. 7, the internally illuminated signboard 100 according to claim 1 includes an internal light source 30 and a display material 20 capable of floating characters and symbols by transmitting light from the internal light source 30. And at least one frame main body 10 constituting the side surface with the side edge of the display material 20 fixed, as shown in FIG. 1, attached to the outer wall of the store, or at the storefront pole It is also used as an external signboard provided on the top.

  The size and shape of this type of internally illuminated signboard 100 are determined by the size and shape of the frame body 10 constituting the interior-lit signboard 100. The size and shape of the frame body 10 are determined according to the installation location. There must be. Therefore, in the internally illuminated sign 100 according to the first aspect, the frame body 10 constituting the signboard can be formed as follows, and the size, particularly the length, can be freely set according to the construction site. I have to.

  That is, in the frame main body 10 of the internally illuminated signboard 100 according to claim 1, as shown in FIG. 2, the side frame 11 having a “U” shape in a plan view and the connecting ends of these side frames 11. It is constituted by two long side frames 12 that connect the parts. The side frame body 11 and the long side frame body 12 are formed of the same shape of a drawing material, but the side frame body 11 is previously formed into a “U” shape in plan view by the drawing material. (Mass production) In advance, when an order is placed, each long-side frame member 12 is cut into a predetermined size and connected between the side frame bodies 11 as shown in FIG.

  In other words, as shown in FIG. 3 to FIG. 5, the internally illuminated signboard 100 according to the first aspect of the present invention is such that each side frame 11 is formed in a “U” shape in plan view. It is suitable when used as a thing directly attached to the store shown on the left side of FIG. If the internally illuminated signboard 100 can be directly attached to a store, its width (the length in the vertical direction shown in the interior illuminated signboard 100 shown on the left side of FIG. 1) is almost unchanged, but the lateral direction This is because the length varies depending on the size of the store to be installed.

  The side frame 11 having a “U” shape in plan view is mass-produced in advance at a factory or the like by the above-described drawing material, and is manufactured as follows. First, from this drawing material, a vertical portion of the side frame 11 and a horizontal portion fixed to both upper and lower ends of this vertical portion are cut out to a predetermined length, and a drawing material that becomes a vertical portion is obtained. An inclined surface of 45 degrees is formed at both ends of the two, and the same inclined surface of 45 degrees is also formed at one end of the two horizontal portions. And each part is welded, contacting the 45 degree inclined surface of each part. The weld 11b formed by this welding appears as shown in FIG.

  If the side frame 11 made in this way is mass-produced in advance as an internally-illuminated signboard 100 having a predetermined width, it can be ordered simply by adjusting the length of the long side frame material 12 to the situation of the construction site. Therefore, the internally illuminated signboard 100 can be constructed in a short time and easily. Of course, each long side frame member 12 may be cut out to a predetermined dimension from a long drawn member.

  When connecting the side frame body 11 and the long side frame member 12, the connecting insertion hole 13a (see FIG. 5 or FIG. 11) formed in the drawing material, that is, the end of the side frame body 11 or the long side frame member 12 is used. The both ends of the first connecting member 13 as shown in FIG. 12 are inserted into the connecting insertion holes 13 a that are open to the side, and the side frame 11 and the long side frame are inserted into the first connecting member 13. The material 12 is fixed. Of course, the outer shape of the first connecting member 13 and the inner shape of each connecting insertion hole 13a are substantially the same, and by inserting the side frame 11 and the long side frame member 12 into both ends of the first connecting member 13, the three members Positioning can be performed correctly.

  Since the first connecting member 13 has such a length that the center portion is located at the boundary portion between the side frame member 11 and the long side frame member 12, the side frame member 11 and the long side frame member are provided. When fixing 12, the short long side frame member 12 or the long side frame member 12 that has been cut by cutting too long is shortened.

  The frame main body 10 formed as described above is sufficient for only one side in the internally illuminated signboard 100 of the type shown on the left side of FIG. 1, but in the internally illuminated signboard 100 of the type shown on the right side of FIG. As shown in FIG. 7, it is sufficient to prepare two and connect them so that they can be opened and closed.

  Therefore, the internally illuminated signboard 100 according to the first aspect of the present invention can not only be mass-produced in advance, but also need to be individually produced in a plan view “U” -shaped side frame body 11, as well as its manufacture. This can be done easily in a short time, not only in the factory but also in the construction site.

In order to solve the above-mentioned problem, the means taken by the invention according to claim 2 is about the internally illuminated signboard 100 of claim 1 above.

  Next, the invention according to each claim configured as described above will be described with respect to an internally illuminated signboard 100, which is the best mode shown in the drawings. Since there are two types, the first example shown in FIG. 7 and the second example shown in FIGS. 8 to 12, each example will be described.

  As shown in FIG. 7, the internally illuminated signboard 100 according to the first embodiment includes an internal light source 30 and a display material capable of floating characters and designs by transmitting light from the internal light source 30. 20 and at least one frame main body 10 that forms a side surface with the side edges of the display material 20 fixed, and like an internally illuminated signboard 100 shown on the left side of FIG. It is attached to the outer wall of the store.

  Generally, the width of the internally illuminated signboard 100 that is directly attached to the wall of the store (the length of the vertically illuminated signboard 100 shown in the left side of FIG. 1 is almost the same as the vertical direction shown in the figure) is almost unchanged. Since the length varies depending on the size of the store to be installed, a change in size and shape requires only a change in length. That is, in the internally illuminated signboard 100 of the first embodiment, only the lateral length of the square signboard can be adjusted.

  Therefore, in the internally illuminated signboard 100 according to the first embodiment, in order to perform only the length adjustment in the lateral direction, the frame main body 10 constituting the signboard 100 as shown in FIG. The "" -shaped side frame body 11 and the two long side frame bodies 12 that connect the connecting end portions of these side frame bodies 11 are formed. The side frame body 11 and the long side frame body 12 are formed of the same shape of a drawing material, but the side frame body 11 is previously formed into a “U” shape in plan view by the drawing material. (Mass production) In advance, each long-side frame member 12 is cut into a predetermined size when ordered, and is connected between the side frame bodies 11 as shown in FIG.

  The side frame 11 is formed as follows. First, it is assumed that the above-mentioned three drawing materials are cut out to the best three, and that one of the widths has an inclined surface of 45 degrees, and the other two are 45 degrees on one end face. Be prepared to have an inclined surface. And it integrates by means, such as welding, so that each 45 degree inclined surface may match.

  In integrating the three drawing materials, as shown by the dotted line and the partial solid line in FIG. 2, the second connecting material 14 as shown in FIG. After storing, welding or fixing was performed from the outside of each drawing material. Thereby, about each side frame 11, the reinforcement of each right angle corner part 11a is performed by the 2nd connection material 14, the improvement of durability of the frame main body 10 whole, and the workability | operativity of the internally illuminated signboard 100 itself And improved.

  As shown in FIG. 6, each second connecting member 14 has two insertion portions 14 a that are orthogonal to each other, and each of these insertion portions 14 a serves as a drawing material constituting the side frame body 11. It is inserted into the formed connecting insertion hole 13a. Each insertion portion 14a has a space 14b, and the space 14b reduces the weight.

  When connecting the side frame body 11 and the long side frame member 12, the first connecting member as shown in FIG. 12 is inserted into the connecting insertion hole 13a (see FIG. 5 or FIG. 11) formed in the drawing member. Both end portions of 13 are inserted, and the side frame body 11 and the long side frame member 12 are fixed to the first connecting member 13.

  When fixing the side frame body 11 and the long side frame material 12 using the first connection material 13, even if the long side frame material 12 is short, the first connection material 13 is assumed to be sufficiently long. Therefore, the short length of the long side frame member 12 can be sufficiently absorbed, and the fixing of the side frame body 11 and the long side frame member 12 is ensured by the first connecting member 13. On the contrary, if the long side frame member 12 is too long, it is only necessary to cut off an excess part at the construction site. The side frame body 11 and the long side frame member 12 are securely fixed by the first connecting member 13.

  The display material 20 must be fixed to the frame body 10 formed in this way, and this fixing may be performed as shown in FIGS. 4 and 5. Since the fixed residual insertion groove 21a is formed on the outer surface of the drawing material for forming the side frame body 11 and the long side frame member 12 as shown in FIG. 5, in the fixed residual insertion groove 21a, As shown in FIG. 4, first, the edge of the display material 20 is pushed in, and the fixing bar 21 is fixed from above. Since this fixed remaining insertion groove 21a is located on the entire periphery of the frame body 10, the four edges of the display material 20 are securely fixed.

  If the display material 20 is only fixed by the fixing bar 21, the display material 20 remains exposed, and the outer surface is covered with a cover plate 40 as shown in FIG. A fastening portion 41 is formed on the inside of the cover plate 40 so as to protrude, and a locking portion 42 corresponding to the fastening portion 41 is formed on the drawing material side. Therefore, the cover plate 40 is fixed to the outer surface of the frame body 10 after the display material 20 has been fixed. In this case, the fastening portions 41 are engaged with the locking portions 42. For example, the integration of the cover plate 40 with the frame body 10 is ensured.

  The number of the frame main body 10 formed in this way may be one in the wall-mounted signboard 100 of the type that is attached to the wall, but the type of the frame main body 10 that is floated in the air like the light-emitting signboard 100 shown on the right side of FIG. It is preferable to use two things that are connected to each other so as to be openable and closable. In addition, a reinforcing bar 17 for attaching the internal light source 30 may be assembled in the frame body 10 as shown in FIG.

  Next, the internally illuminated signboard 100 according to the second embodiment will be described with reference to FIGS. 8 to 12. In FIG. 8, the frame main body 10 constituting the internally illuminated signboard 100 is completely integrated. The top view before doing is shown. The difference of the second embodiment from the first embodiment is that a corner frame member 15 having an “L” shape in plan view is used for each corner. Other than this, it is basically the same as the internally illuminated signboard 100 of the first embodiment.

  Each corner frame member 15 has a plan view shape as shown in FIGS. 8 and 9. In the internally illuminated signboard 100 of this embodiment 23, each of the corner frame members 15 is divided into four corner frame members 15. The frame main body 10 is arranged in the corner portion, and the corner frame members 15 are connected by a side frame member 16 having a predetermined length.

  The internally illuminated signboard 100 according to the second embodiment is suitable for, for example, the internally illuminated signboard 100 shown on the right side of FIG. 1, and the dimensions in the vertical direction as well as the horizontal direction are in accordance with the order. It can be made to be. In other words, this internally illuminated signboard 100 has the dimension between the two corner frame members 15 arranged in the vertical direction in FIG. 8 and the length adjustment of the side frame member 16 arranged between them. It is something that can be done. Of course, also in this internally illuminated signboard 100, when the corner frame members 15 and the side frame members 16 are connected, it goes without saying that the first connecting member 13 used in the first embodiment is used.

  Further, in the internally illuminated signboard 100 of the second embodiment, the second reinforcing material is inserted into the right-angled corner portion 15a of each corner frame body 15 and the reinforcing material insertion hole 13a of the drawing material forming the corner portion 15a. 14 is housed, and the right-angled corner portion 15a is reinforced by using the second reinforcing member 14.
