Description

The present invention relates to box-shaped letters, and more specifically to box-shaped letters used as three-dimensional character signs.

Conventionally, box-shaped letter signs with a box-shaped cross section have been known as signs that display three-dimensional letters and marks and are used primarily outdoors to display store names, logos, etc. (for example, see Patent Document 1).

In Patent Document 1, the box-shaped letter signboard (1) is configured with a box-shaped cross section and is made up of a display section (2) made of resin, a side plate section (3) that covers the outer peripheral edge (2a) of the display section (2), and a bottom plate section (4) that closes the back surface (2b) side of the display section (2) (see Figure 1 of Patent Document 1).

In addition, a generally L-shaped fixing member (8) is joined to the back surface (4a) of the bottom plate portion (4) at one side (8a) at a position corresponding to the screw hole (3a) of the side plate portion (3), and a screw hole (8c) is provided on the other side (8b) (see FIG. 2 of Patent Document 1). The bottom plate portion (4) is then 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.

Known examples of the box-shaped letter signs mentioned above (hereinafter also simply referred to as "box-shaped letters") include the L-shaped lunchbox-style box-shaped letters shown in Figure 7 and the full-face lunchbox-style box-shaped letters shown in Figure 8.

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 side plate 53 of the lid member 5 is screwed (screwed) to the L-shaped cross-section plate 33 with a screw SC, so that the lid member 5 is assembled to the receiving member 3.

As shown in FIG. 8, the full-face lunchbox-style box letter 1 is a box-shaped letter assembled by covering a container-shaped receiving member 4 consisting of a back plate 41 and a side plate 43 with a lid member 5. Simply put, the full-face lunchbox-style 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-style box letter 1, the side plate 53 of the lid member 5 is screwed (screwed) into the side plate 43 of the receiving member 4 with a screw SC, thereby assembling the lid member 5 to the receiving member 4.

JP 2007-72053 A

In the above-mentioned Patent Document 1, the side portion (3) is screwed to the fixing member (8) with a screw (9), so the head of the screw (9) is exposed on the external surface (appearance) of the side portion (3) (see Figure 1 of Patent Document 1), which is not necessarily an attractive appearance.

Furthermore, the L-shaped lunchbox style box letter 1 (see FIG. 7) and the full-face lunchbox style box letter 1 (see FIG. 8) described above also do not look good because the heads of the screws SC are exposed on the side panel 53 of the cover member 5.

The present invention aims to provide box-shaped letters that can be fixed to a receiving member without exposing the fasteners on the side of the lid member.

To achieve the above object, a box-shaped letter is provided, which comprises a receiving member including a back plate and a protruding member protruding forward from the back plate, and a cover member that is placed over the receiving member and includes a front plate facing the back plate and a side plate extending rearward from the outer periphery of the front plate, the rear surface of the front plate being magnetic, and a magnet being provided at the front end of the protruding member, and when the cover member is placed over the receiving member, the protruding member is disposed inside the cover member and the magnet abuts against the rear surface.

Here, it is preferable that the protruding member is disposed close to the side plate, and the portion of the side plate facing upward in the out-of-plane direction and the protruding member facing said portion are secured by screws.

The protruding member is preferably made of a bent plate having a U-shaped cross section, one surface of the protruding member facing the U-shape is welded to the front surface of the back plate, and the magnet is preferably provided on the other surface of the protruding member facing the U-shape.

The present invention also provides a box-shaped letter comprising a receiving member including a back plate, a first side plate extending forward from the outer periphery of the back plate, and a protruding member protruding forward from the back plate inside the first side plate, and a cover member to be placed on the receiving member, the cover member including a front plate facing the back plate and a second side plate extending rearward from the outer periphery of the front plate, the rear surface of the front plate being magnetic, and a magnet being provided at the front end of the protruding member, and when the cover member is placed on the receiving member, the protruding member is disposed inside the cover member and the magnet abuts against the rear surface.

According to the present invention, a protruding member is disposed inside the lid member, and the lid member is fixed to the receiving member by a magnet provided on the protruding member. Therefore, in the case of box-shaped letters, it is possible to fix the lid member to the receiving member without exposing the fastener on the side of the lid member.

1. Embodiment
A box-shaped letter 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.

As shown in Figures 1 and 2, the box-shaped letter 1 is composed of a receiving member 3 and a lid member 5 that can be attached and detached to the receiving member 3.

The receiving member 3 is composed of a back plate 31 and a U-shaped cross-section plate 33 that protrudes forward from the back plate 31.

As shown in Figures 2 and 3, one of the opposing faces 331 of the U-shaped cross-section plate 33 is welded to the front face 31F of the back plate 31.

On the other hand, a neodymium magnet 6 is screwed to the other surface 333 of the U-shaped cross section plate 33, which faces the U-shape.

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

The cover member 5 is composed of a front plate 51 that faces the back plate 31 of the receiving member 3, and a side plate 53 that extends rearward from the outer periphery of the front plate 51. In this embodiment, the cover member 5 is made of stainless steel (SUS), which is both magnetic and corrosion-resistant. In other words, both the front plate 51 and the side plate 53 are magnetic.

As shown in FIG. 1, the box-shaped letter 1 is fixed with the cover member 5 covering the receiving member 3. When the cover member 5 is covering 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 lunchbox type box-shaped letter 1, the U-shaped cross-section plate 33 is disposed close to the side plate 53 of the cover member 5.

When the cover member 5 is placed over 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, the cover member 5 is made of magnetic stainless steel, so 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.

By the way, the box-shaped letters 1 are basically installed at a position higher than human eye height. 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 marred. 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 marred.

Therefore, in this embodiment, the box-shaped letters 1 are secured with screws in an area that cannot be seen by a person looking at the box-shaped letters 1 when looking up at them. Although it is usually possible to secure the lid member 5 to the receiving member 3 using only the magnetic force of the neodymium magnets 6, this is to prevent the lid member 5 from falling off the receiving member 3 if an unexpected load is applied to the lid member 5.

Specifically, the portion of the side plate 53 of the cover member 5 that faces upward in the out-of-plane direction is fastened with a screw to the U-shaped cross-section plate 33 that faces said portion. This is because, when looking up at the installed box-shaped letter 1, it is highly likely that the portion of the side plate 53 of the cover member 5 that faces upward in the out-of-plane direction will be positioned 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 a screw). On the other hand, the lower side plate 53 and the lower U-shaped cross-section plate 33 are not fastened with a screw.

According to the embodiment described above, a U-shaped cross section plate 33 is disposed inside the cover member 5, and a 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 surface 51R of the front plate 51 that constitutes part of the cover member 5, thereby fixing the cover member 5 to the receiving member 3.

Therefore, in the L-shaped lunchbox-style box-shaped letter 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.

In addition, according to the above-mentioned embodiment, the portion of the side plate 53 of the cover member 5 that faces upward in the out-of-plane direction and the U-shaped cross-section plate 33 that faces said portion are screwed together. Therefore, when looking up at the installed box-shaped letter 1, the screwed portion is not visible, and it is possible to reliably prevent the cover member 5 from falling off.

In addition, according to the above-described embodiment, the U-shaped cross-section plate 33 is configured with two opposing faces 331 and 333. This makes it possible to bring one face 331 into surface contact with the front face 31F of the back plate 31, improving workability during welding work. In addition, by placing the neodymium magnet 6 on the other face 333, the neodymium magnet 6 can be stably installed relative to the U-shaped cross-section plate 33.

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.

For example, in the above embodiment, the concept 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). The full-face lunchbox-style box-type letter 1 will be described below with reference to FIG. 5 and FIG. 6.

As shown in Figures 5 and 6, the full-face lunchbox-style box-shaped letter 1 is composed of a receiving member 4 and a cover member 5. The receiving member 4 is composed of a back plate 41 and a side plate 43 that extends from the outer periphery of the back plate 41 toward the front side (the front of the letter).

The back plate 41 is provided with a U-shaped cross section plate 33 that protrudes forward from the back plate 41 inside the side plate 43. One surface 331 of the U-shaped cross section plate 33 that faces the U-shape 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 surface 333 of the U-shaped cross section plate 33 that faces the U-shape.

As shown in FIG. 5, when the cover member 5 is placed over the receiving member 4, 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 magnetic, 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 4.

When the cover member 5 is placed over the receiving member 4, the side plate 53 of the cover member 5 is positioned closer to the outside than the side plate 43 of the receiving member 4. The portion of the side plate 53 of the cover member 5 that faces upward in the out-of-plane direction is screwed to the side plate 43 that faces this portion.

According to the above-mentioned modified example, in a full-face lunchbox-style box-shaped letter 1, it is possible to fix the cover member 5 to the receiving member 4 without exposing the head of the screw SC on the side surface 53 of the cover member 5, at least in the visible range.

In addition, in the above-described embodiment, the U-shaped cross-section plate 33 shown in FIG. 2 is given as an example of a protruding member, but this is not limited thereto, and an L-shaped cross-section plate, a pipe, or the like may also be used as the protruding member.

In the above embodiment, the entire cover member 5 is made of magnetic stainless steel, but this is not limiting. The cover member 5 may be made of a non-magnetic material, and a magnetic stainless steel plate or the like may be provided on the rear surface 51R of the front plate 51 that constitutes part of the cover member 5. Even in this configuration, the neodymium magnet 6 can be attracted to the rear surface 51R of the front plate 51.

As described above, the present invention is suitable for L-shaped lunchbox-style box letters and full-surface lunchbox-style box letters used as three-dimensional character signs.
