Summary of the Invention

Problems to be Solved by the Invention

[0005] An object of the present invention is to provide a display case that allows a user to select and use any of storage, appreciation, or portability. [Means for solving the problem]

[0006] As a means for solving the above problems, the present invention provides a display case comprising a front panel that allows the interior to be seen, and a back panel that is integrated with the front panel in a superimposed state, wherein at least one of the front panel or the back panel is provided with a detachable mounting portion.

[0007] With this configuration, depending on the user's purpose, the mounting part can be separated when used for storage, and it can be used as is without separation when used for (self) display or portability.

[0008] Preferably, the mounting portion is provided in the upper central part of the back panel.

[0009] This configuration allows the display case to be mounted in a balanced manner in the desired location using the simplest possible configuration: a single mounting point.

[0010] The mounting portion preferably has a locking structure that can be locked into the portion to be mounted.

[0011] With this configuration, the mounting part can be easily attached to a desired location, such as a wall, which is the mounting surface.

[0012] The mounting portion is a tongue-shaped piece having an opening, and it is preferable that the panel on which the mounting portion is formed has a protrusion that projects into the opening.

[0013] With this configuration, the two panels can be easily separated by using the protrusions to flex one of the panels.

[0014] The mounting portion preferably has a thin-walled structure that facilitates separation.

[0015] With this configuration, the mounting part can be easily separated when the display case is used for storage.

[0016] The back panel has a base portion and a flange portion located around the base portion, and the front panel has a bulge portion that covers the base portion and forms a uniform gap accommodation space, and a flange portion located around the bulge portion and overlapping the flange portion, and preferably at least one of the flange portions has a contact portion that contacts the other flange portion around its entire circumference.

[0017] With this configuration, cards can be stored in the storage space formed between the base and the bulging part. In addition, since airtightness is maintained by the contact surface where the flanges overlap, dust and water droplets can be effectively prevented from entering the interior.

[0018] Preferably, the contact portion is composed of protrusions formed at least two locations, one on the inside and one on the outside.

[0019] With this configuration, the action of two or more protrusions can more effectively prevent dust, water droplets, and other contaminants from entering the interior.

[0020] Preferably, a first locking portion is formed at the center of one end of either the front panel or the back panel, and second locking portions are formed at the other ends on both sides, while a first locking receiving portion and a second locking receiving portion are formed at positions corresponding to the first locking portion and the second locking portion on the remaining panel.

[0021] With this configuration, the front and back panels can be overlapped and integrated, even though there are only three locking mechanisms.

[0022] Preferably, either the front panel or the back panel has a cutout near the locking position of the second locking portion and the second locking receiver, thereby exposing a portion of the other.

[0023] According to this configuration, by inserting a claw or the like into the joint surface of both panels from the portion exposed by the excision part, in combination with the use of the convex part, the separation work of the front panel and the back panel can be further facilitated.

Effect of the Invention

[0024] According to the present invention, since the attachment part is provided so as to be separable, it is possible to cope with both storage and display according to the user's usage.

Mode for Carrying Out the Invention

[0026] Hereinafter, embodiments according to the present invention will be described with reference to the accompanying drawings. In the following description, terms indicating specific directions and positions (for example, terms including "upper", "lower", "side", "end") are used as necessary, but the use of these terms is for facilitating the understanding of the invention with reference to the drawings, and the technical scope of the present invention is not limited by the meanings of these terms. Further, the following description is merely illustrative in nature and is not intended to limit the present invention, its applications, or its uses.

[0027] Figure 1 is a perspective view of a display case according to this embodiment. This display case consists of a front panel 1 and a back panel 2. Both the front panel 1 and the back panel 2 are rectangular in plan view and are formed by molding a translucent material, such as polycarbonate.

[0028] As shown in Figure 2, the front panel 1 is composed of a bulge 3 and a first flange 4 extending outward from its periphery. A first recess 5 is formed on the bottom side of the bulge 3, as shown in Figure 3. As a result, the bulge 3 has approximately the same thickness as the first flange 4. Here, the average thickness is set to 1.2 mm.

[0029] As shown in Figure 4, the inner surface 5a of the first recess 5 gradually slopes inward toward the bottom surface 5b. Here, the inclination angle θ1 of the inner surface 5a of the first recess 5 with respect to a plane P1 that extends in the short direction X of the first recess 5 and is perpendicular to the surface 3a of the bulge 3 is designed to be 5 degrees (since the angle of the inner surface 5a of the first recess 5 is the same as the angle of the outer surface 3b of the bulge 3, Figure 4 illustrates the relationship with the outer surface 3b). The inclination angle θ1 can be in the range of 1 to 30 degrees, and is preferably in the range of 1 to 5 degrees.

[0030] Returning to Figure 2, the first flange portion 4 has a first locking portion 6 formed at the center of the edge located on one end of the front panel 1. As shown in Figure 4, the first locking portion 6 has a locking piece 6a that extends perpendicularly downward from the outer edge of the bottom surface of the first flange portion 4, and a locking claw 6b that protrudes inward, i.e., toward the first recess 5, at the tip of the locking piece 6a. The slit 6c visible on the surface of the first flange portion 4 is formed during the molding process when the locking claw 6b is formed due to the structure of the mold.

[0031] Second locking portions 7 are formed on both other ends of the first flange portion 4. The second locking portion 7 has a similar configuration to the first locking portion 6, and as shown in Figure 5, it has a locking claw 7b at the tip of the locking piece 7a.

[0032] As shown in Figure 3, the bottom surface of the first flange portion 4 has a first projection 8 and a second projection 9 that protrude from the outer edge and inner edge (the boundary portion with the second recess 12) along its entire circumference, respectively. The first projection 8 and the second projection 9 have the same projection dimensions. However, the first projection 8, which is provided along the outer edge, is not provided in the portion corresponding to the second locking portion 7 for structural reasons. The second projection 9 is provided along the opening edge of the first recess 5. In other words, the inner edge of the second projection 9 coincides with the position of the opening edge of the first recess 5. Furthermore, by providing these first projection 8 and second projection 9, the rigidity is increased, making it possible to form the front panel 1 with a thin wall.

[0033] As shown in Figure 2, the back panel 2 consists of a base portion 10 and a second flange portion 11 extending outward from its periphery. As shown in Figure 3, a second recess 12 is formed on the bottom surface of the base portion 10. As a result, the base portion 10 and the second flange portion 11 have approximately the same thickness. Here, as with the front panel 1, the average thickness is 1.2 mm.

[0034] Returning to Figure 2, the surface of the base portion 10 consists of a base surface 10a and four side surfaces 10b around it. The base surface 10a is formed to have a surface area that allows a trading card (not shown) to be placed on it without protruding from its surroundings when it is housed in a transparent bag (over sleeve), that is, approximately the same size as the over sleeve viewed from above. The side surfaces 10b gradually incline outwards as they move away from the base surface 10a. The lower end position of the side surfaces 10b approximately coincides with the inner edge position of the second projection 9. As shown in Figure 4, the inclination angle θ2 of the side surfaces 10b is designed to be 7 degrees with respect to a plane P2 that extends in the short-side direction XX of the back panel 2 and is perpendicular to the base surface 10a. The inclination angle θ2 can be in the range of 2 to 31 degrees, and preferably in the range of 2 to 6 degrees. However, this inclination angle must be greater than the inclination angle of the inner surface 5a of the first recess 5, and it is preferable that this angle be, for example, 1 degree or more greater.

[0035] Returning to Figure 2, a first locking receiver 13 is formed at the center of the edge of the second flange 11 located at one end of the back panel 2, and second locking receivers 14 are formed at the other ends on both sides. The first locking receiver 13 and the second locking receiver 14 are provided at positions corresponding to the first locking portion 6 and the second locking portion 7 formed on the front panel 1, respectively. The first locking receiver 13 is formed in a notch 15 formed at the center of the edge of the second flange 11 located at one end of the back panel 2. That is, as shown in Figure 5, the edge of the recessed portion due to the notch 15 has a stepped shape, and this portion is the first locking receiver 13. The second locking receiver 14 has a similar configuration to the first locking receiver 13.

[0036] A cutout portion 16 is formed near the second locking receiving portion 14, in this case adjacent to the second locking receiving portion 14. The cutout portion 16 has the same recess dimensions as the notch portion 15 formed to create the second locking receiving portion 14, and its inner edge is located on the same straight line. As a result, when the front panel 1 and the back panel 2 are superimposed, a portion of the front panel 1 is exposed when viewed from the back panel side. This exposed portion will be used as a finger grip portion, which will be described later.

[0037] As shown in Figure 2, and more specifically in Figure 6, a tongue piece 17, which serves as a mounting portion, is provided at the center of the edge of the second flange portion 11 located on the other end of the back panel 2. Here, the tongue piece 17 is symmetrically arched, with an opening 18 formed on its inner side. An arc-shaped recess 19 is formed on the opening edge of the tongue piece 17, on the center line that divides the back panel 2 into left and right halves. The part of a pin, such as a pushpin stuck into a wall, is placed in this recess 19, allowing the display case to be supported stably. However, the tongue piece 17 is not limited to an arch shape; it can also be a triangular shape (isosceles or equilateral triangle). Furthermore, a thin-walled portion 20 is formed at the base of the tongue piece 17, i.e., the connection portion with the other end edge of the back panel 2. The thin-walled portion 20 can be easily cut using scissors or a cutter.

[0038] A protrusion 21 is formed at the center of the edge of the second flange portion 11 located on the other end of the back panel 2, projecting into the opening 18 of the tongue piece 17. The protrusion 21 is a finger grip, and by pressing this protrusion 21, the surrounding area can be bent, creating a gap between it and the front panel 1.

[0039] As shown in Figure 3, a ridge 2a is formed on the bottom edge of the back panel 2. This ridge 2a is also formed on the outer edge of the tongue piece 17, but structurally it is not provided on the first locking receiving portion 13, the second locking receiving portion 14, and the cut portion 16. By providing the ridge 2a, when the back panel 2 is placed on a desk or the like, the bottom surface does not come into full contact with the desk surface, making it easier to handle. In addition, by providing the ridge 2a, the overall rigidity can be increased, similar to the front panel 1, so it is possible to form the back panel 2 with a thin wall.

[0040] Furthermore, all areas where edges might form on the front panel 1 and back panel 2 are rounded (R-shaped). Therefore, there is no risk of users cutting their fingers or other malfunctions caused by sharp edges, nor is there any concern about stress concentration in certain areas causing cracks or other damage.

[0041] The display case having the above configuration is used as follows.

[0042] First, the front panel 1 and the back panel 2 are separated. To separate the two panels, a finger is placed on a portion of the front panel 1 that has been exposed by forming a cutout portion 16 in the back panel 2, and it is pushed in to separate it from the back panel 2. This can be done on either the left or right exposed portion, or by pushing in the protrusion 21 in the center of the upper end. This causes a portion of the front panel 1 to elastically deform, releasing the locking state of the second locking portion 7 and the second locking receiving portion 14. Furthermore, releasing the locking state of the first locking portion 6 and the first locking receiving portion 13 separates the front panel 1 and the back panel 2. When pushing in the protrusion 21, the thumb is placed on the tongue piece 17, and the tip of the fingernail is pressed against the protrusion 21, which easily flexes the center of the upper end of the back panel 2, creating a gap between it and the front panel 1, allowing the fingertip to be pushed in. This makes the panel separation work easier than using the exposed portion.

[0043] Once the front panel 1 and back panel 2 are separated, a trading card, for example, housed in an over-sleeve, is placed on the surface of the base portion 10 of the back panel 2. The size of the base surface is approximately the same as the surface area of ​​the over-sleeve. Therefore, it is easy to align the cards. Note that the display case can contain not only trading cards, but also all kinds of cards such as photographs and IC cards.

[0044] Next, the front panel 1 is placed on top of the back panel 2. The side surface 10b of the base portion 10 of the back panel 2 has a larger inclination angle than the inner surface of the bulge portion 3 of the front panel 1. In other words, the maximum opening of the bulge portion 3 is generally larger than the surface of the base. Therefore, the front panel 1 can be smoothly placed on top of the back panel 2. As the base portion 10 enters the first recess 5 of the bulge portion 3, the lower side of the base portion 10 gradually approaches the lower inner surface of the first recess 5, and the gap between both lower edges disappears. In other words, misalignment of the front panel 1 in the planar direction relative to the back panel 2 is completely prevented, and a storage space is obtained by forming a certain gap between the base surface of the base portion 10 and the bottom surface of the bulge portion 3. Trading cards housed in over sleeves are arranged within the storage space with almost no gaps. At this time, the first protrusion 8 and the second protrusion 9 formed on the first flange portion 4 of the front panel 1 come into contact with the surface of the second flange portion 11 of the back panel 2. This maintains airtightness within the storage space and effectively prevents the intrusion of dust, water droplets, and other elements from the outside.

[0045] When the display case is used for display purposes, it can be hung on a wall or the like using the tab 17. For example, a thumbtack can be inserted into the wall, and the pin can be placed in the recess 19 of the opening 18 formed in the tab 17 of the display case.

[0046] Furthermore, when using the display case for portable use, one can connect, for example, the string of a hanging name tag or a clip or strap attached to the string to the opening 18 of the tongue piece 17.

[0047] Furthermore, when the display case is to be stored in a drawer or the like, the thin portion 20 formed on the tongue 17 can be cut off by repeatedly bending it in the opposite direction with scissors, a cutter, or, if necessary, by hand. However, the protruding portion 21 is left intact to separate the front panel 1 and the back panel 2, which facilitates the subsequent replacement of cards.

[0048] It should be noted that the present invention is not limited to the configuration described in the above embodiments, and various modifications are possible.

[0049] In the above embodiment, both the front panel 1 and the back panel 2 are made of a light-transmitting material, but only the front panel 1 can also be made in this way. Furthermore, the material used is not limited to polycarbonate; other synthetic resin materials such as acrylic, PVC (polyvinyl chloride), PET (polyethylene terephthalate), glass fiber reinforced plastic (FRP), and polyether ether ketone (PEEK) can also be used. In addition, the display case itself can be made in various sizes depending on the size of the photographs or other items to be stored inside.

[0050] In the above embodiment, the mounting portion is provided on the back panel 2, but it can also be provided on the front panel 1. Furthermore, although the mounting portion is provided only in one place at the center of the upper end, the number and location are not particularly limited to this. For example, it can be provided in two places on both sides of the upper end, or equally divided into three places at the upper end.

[0051] In the above embodiment, the mounting portion is formed in an arch shape, but it is not limited to this and can take other forms. For example, it can be hook-shaped, or it can be a rectangular plate with a hole in it.

[0052] In the above embodiment, the first protrusion 8 and the second protrusion 9 are provided on the first flange portion 4 of the front panel 1, but they may also be provided on the second flange portion 11 of the back panel 2, or they may be provided on both and butted together. Furthermore, the number of protrusions is not limited to two; there may be one or three or more.

[0053] Although not specifically mentioned in the above embodiment, multiple protrusions made of silicone or the like may be formed on at least one of the front panel 1 or the back panel 2. These protrusions are used to hold and position the cards placed in the storage space between the panels. If the protrusions are formed on the surface of the base, it becomes easy to align the cards even if they are trading cards or small items such as business cards or name tags, and it is also possible to properly prevent misalignment when the panels are stacked.

[0054] In the above embodiment, the display case was rectangular in plan view, but it can also be made into other shapes such as a circle or a triangle in plan view. [Explanation of symbols]
