Description

[Technical field]

[0001] The present invention relates to box-type letters, and more particularly to box-type letters used as three-dimensional character signs. [Background technology]

[0002] 2. Description of the Related Art Conventionally, box-shaped letter signs having a box-shaped cross section have been known as signs that form three-dimensional letters or marks and are used primarily outdoors to display store names, logos, and the like (for example, Patent Document 1).

[0003] In Patent Document 1, a box-shaped letter signboard (1) has a box-shaped cross section and is composed of a display section (2) made of resin, a side panel section (3) covering the outer peripheral edge (2a) of the display section (2), and a bottom panel section (4) closing the back surface (2b) of the display section (2) (see FIG. 1 of Patent Document 1).

[0004] Furthermore, a substantially L-shaped fixing member (8) is joined at one side (8a) of the back surface (4a) of the bottom plate portion (4) at a position corresponding to the screw hole (3a) of the side plate portion (3), and a screw hole (8c) is provided at the other side (8b) (see FIG. 2 of Patent Document 1). The bottom plate portion (4) is inserted between the side plate portions (3), and a screw (9) is screwed into the screw hole (3a) of the side plate portion (3) and the screw hole (8c) of the fixing member (8). As a result, the side plate portion (3) and the bottom plate portion (4) are assembled.

[0005] Known examples of the box-type letter signboards described above (hereinafter also simply referred to as "box-type letters") include L-shaped lunchbox-style box-type letters as shown in FIG. 7 and full-face lunchbox-style box-type letters as shown in FIG.

[0006] As shown in Fig. 7, the L-shaped lunchbox style box letter 1 is a box letter assembled by covering a lid member 5 with a receiving member 3 composed of a back plate 31 and an L-shaped cross-section plate 33. In the L-shaped lunchbox style box letter 1, the lid member 5 is assembled to the receiving member 3 by screwing (screw-fastening) a side plate 53 of the lid member 5 to the L-shaped cross-section plate 33 with a screw SC.

[0007] As shown in Fig. 8, the full-face lunchbox-type box letter 1 is a box-type letter assembled by covering a container-like receiving member 4 composed of a back plate 41 and a side plate 43 with a lid member 5. Simply put, the full-face lunchbox-type box letter 1 is constructed so that the receiving member 4 and the lid member 5 have the same shape and overlap each other. In the full-face lunchbox-type box letter 1, the side plate 53 of the lid member 5 is screwed (screwed) to the side plate 43 of the receiving member 4 with a screw SC, thereby assembling the lid member 5 to the receiving member 4.

[0018] <1. Embodiment> Box-shaped letters according to an embodiment of the present invention will be described with reference to Figures 1 to 4. In the following, an L-shaped lunchbox style box-shaped letter 1 (see Figure 1) will be illustrated as an example of the box-shaped letter according to the present invention.

[0019] As shown in FIG. 1 and FIG. 2, the box-shaped letter 1 is configured to include a receiving member 3 and a cover member 5 that is detachable from the receiving member 3.

[0020] The receiving member 3 is configured to include a back plate 31 and a plate 33 having a U-shaped cross section that protrudes forward from the back plate 31.

[0021] As shown in FIGS. 2 and 3, one surface 331 of the U-shaped cross section plate 33 facing the U-shape is welded to the front surface 31F of the back plate 31.

[0022] On the other hand, a neodymium magnet 6 is fixed with a screw to the other surface 333 of the plate 33 having a U-shaped cross section, the other surface 333 facing the U-shape.

[0023] The U-shaped cross section plate 33 is an example of a protruding member according to the present invention, and in this embodiment, is configured as a bent plate having a U-shaped cross section.

[0024] The cover member 5 is configured to include a front plate 51 facing the back plate 31 of the receiving member 3, and a side plate 53 extending rearward from the outer peripheral edge of the front plate 51. In this embodiment, stainless steel (SUS), which is both magnetic and corrosion-resistant, is used as the material for the cover member 5. In other words, both the front plate 51 and the side plate 53 are magnetic.

[0025] As shown in Fig. 1, the box-shaped letter 1 is fixed in a state where the cover member 5 is placed on the receiving member 3. When the cover member 5 is placed on the receiving member 3, the side plate 53 of the cover member 5 is disposed outside the U-shaped cross section plate 33. In other words, the U-shaped cross section plate 33 is disposed inside the cover member 5. In the L-shaped lunch box type box letter 1, the U-shaped cross section plate 33 is disposed close to the side plate 53 of the cover member 5.

[0026] Furthermore, when the cover member 5 is placed on the receiving member 3, the neodymium magnet 6 abuts against the rear surface 51R of the front plate 51 of the cover member 5. As described above, since the cover member 5 is made of magnetic stainless steel, the neodymium magnet 6 is attracted to the front plate 51 of the cover member 5 by magnetic force. This fixes the cover member 5 to the receiving member 3.

[0027] Incidentally, the box-shaped letters 1 are basically installed at a position higher than the height of a person's eyes. Therefore, as long as the screws are not attached within a range that can be seen by a person looking at the installed box-shaped letters 1 when looking up at them, the appearance will not be impaired. Conversely, even if the screws are attached within a range that cannot be seen by a person looking at the installed box-shaped letters 1 when looking up at them, the appearance will not be impaired.

[0028] Therefore, in this embodiment, the screws are fastened in a range that cannot be seen by a person looking at the box-shaped letters 1 when looking up at the box-shaped letters 1. Although it is usually possible to fix the cover member 5 to the receiving member 3 only by the magnetic force of the neodymium magnets 6, this is to prevent the cover member 5 from falling off the receiving member 3 if an unexpected load is applied to the cover member 5.

[0029] Specifically, the portion of the side plate 53 of the cover member 5 facing upward in the out-of-plane direction and the U-shaped cross-section plate 33 facing the portion are fastened with screws. This is because, when looking up at the installed box-shaped letter 1, the portion of the side plate 53 of the cover member 5 facing upward in the out-of-plane direction is highly likely to be located in a position that cannot be seen by a person looking at the box-shaped letter 1. In the example of Fig. 1, the upper side plate 53 and the upper U-shaped cross-section plate 33 are screwed together with a screw SC (fastened with screws). On the other hand, the lower side plate 53 and the lower U-shaped cross-section plate 33 are not fastened with screws.

[0030] According to the embodiment described above, the U-shaped cross section plate 33 is disposed inside the cover member 5, and the neodymium magnet 6 is provided on the front side of one of the opposing faces 333 of the U-shaped cross section plate 33. The neodymium magnet 6 comes into contact with and is attracted to the rear face 51R of the front panel 51 that constitutes a part of the cover member 5, thereby fixing the cover member 5 to the receiving member 3.

[0031] Therefore, in the L-shaped lunchbox-style box-shaped character 1, it is possible to fix the lid member 5 to the receiving member 3 without exposing the head of the screw SC to the side surface 53 of the lid member 5, at least within the visible range. More specifically, as shown in Fig. 4, in the conventional method, the head of the screw SC is exposed to the side surface of the lid member, but by using the method of the above-mentioned embodiment (the present invention), the head of the screw SC is not exposed at all to the side surface of the lid member.

[0032] According to the embodiment described above, the portion of the side plate 53 of the cover member 5 facing upward in the out-of-plane direction is fixed with a screw to the U-shaped cross section plate 33 facing the portion. Therefore, when looking up at the installed box-shaped letter 1, the portion fixed with the screw is not visible, and it is possible to reliably prevent the cover member 5 from falling off.

[0033] Furthermore, according to the embodiment described above, the U-shaped cross section plate 33 is configured to have two opposing faces 331 and 333. This allows one face 331 to be in surface contact with the front surface 31F of the back plate 31, improving workability in welding work. Furthermore, by placing the neodymium magnet 6 on the other face 333, the neodymium magnet 6 can be stably installed on the U-shaped cross section plate 33.

[0034] <2. Modifications> The box-shaped characters according to the present invention are not limited to the above-described embodiment, and various modifications and improvements are possible within the scope of the claims.

[0035] For example, in the above embodiment, the idea of ​​the present invention is applied to an L-shaped lunchbox-style box-type letter 1 (see FIG. 1), but the present invention is not limited to this and may be applied to a full-face lunchbox-style box-type letter 1 (see FIG. 5). Hereinafter, the full-face lunchbox-style box-type letter 1 will be described with reference to FIGS. 5 and 6.

[0036] As shown in FIGS. 5 and 6, the full-face lunch box type box-shaped character 1 is configured to include a receiving member 4 and a lid member 5. The receiving member 4 is composed of a back plate 41 and side plates 43 extending from the outer peripheral end of the back plate 41 toward the front side (front of the character).

[0037] On the back plate 41, a U-shaped cross-section plate 33 protruding forward from the back plate 41 inside the side plates 43 is provided. One of the opposing surfaces 331 of the U-shaped cross-section plate 33 is welded to the front surface 41F of the back plate 41. On the other hand, a neodymium magnet 6 is screwed to the other opposing surface 333 of the U-shaped cross-section plate 33.

[0038] As shown in FIG. 5, in the state where the lid member 5 is placed on the receiving member 4, the neodymium magnet 6 abuts against the rear surface 51R of the front plate 51 of the lid member 5. As described above, since the lid member 5 has magnetism, the neodymium magnet 6 is attracted to the front plate 51 of the lid member 5 by magnetic force. Thereby, the lid member 5 is fixed to the receiving member 4.

[0039] Also, in the state where the lid member 5 is placed on the receiving member 4, the side plates 53 of the lid member 5 are arranged in proximity outside the side plates 43 of the receiving member 4. And a portion of the side plate 53 of the lid member 5 whose out-of-plane direction is upward and the side plate 43 facing the portion are screwed together.

[0040] According to the above-described modification, in the full-face lunch box type box-shaped character 1, at least in the visible range, it is possible to fix the lid member 5 to the receiving member 4 without exposing the head of the screw SC on the side surface 53 of the lid member 5.

[0041] Also, in the above-described embodiment, the U-shaped cross-section plate 33 shown in FIG. 2 is exemplified as an example of the protruding member, but it is not limited thereto, and an L-shaped cross-section plate, a pipe, or the like may be used as the protruding member.

[0042] In the above embodiment, the entire cover member 5 is made of magnetic stainless steel, but this is not limiting. Cover member 5 may be made of a non-magnetic material, and a magnetic stainless steel plate or the like may be provided on rear surface 51R of front plate 51 that constitutes part of cover member 5. Even in this configuration, neodymium magnet 6 can be brought into contact with rear surface 51R of front plate 51 and attracted thereto. [Industrial Applicability]
