[0001] The present invention relates to a shelf door kit, a shelf door mounting component kit, and a top plate groove component.

Background Art

[0002] There is a commercially available shelf that houses objects in a space surrounded by a top plate, a bottom plate, and left and right side plates.

[0003] Also, a mortise-and-tenon type is known as one method of attaching a door or a back panel to a shelf. For example, Patent Document 1 describes that "a shallow groove 41 having a depth of about 4 mm is formed at the rear part of the upper surface of the shelf boards 2 and 2A, and a deep groove 42 having a depth of about 10 mm is formed at the rear part of the lower surface of the shelf boards 2 and 2A and at the rear part of the lower surface of the top plate part 22 corresponding to the shallow groove 41. A back panel 43 having a height dimension slightly lower than the interval between the opposing shallow groove 41 and deep groove 42 is formed. This back panel 43 has a thickness narrower than the width of the both grooves 41 and 42. As shown in FIG. 10, after inserting the upper edge of the back panel 43 obliquely into the deep groove 42 from the rear, its lower edge is pushed forward and fitted into the shallow groove 41, and it is incorporated into the back of the prefabricated furniture 1 by a so-called mortise-and-tenon type" (see paragraph

[0016] of Patent Document 1, FIG. 10).

Summary of the Invention

Problems to be Solved by the Invention

[0005] Commercially available shelves (hereinafter also referred to as "commercial shelves") come in a variety of sizes and with different numbers of tiers, such as 3-tier shelves and 2-tier shelves. By using commercially available shelves and attaching transparent doors, it is possible to create display shelves (hereinafter also referred to as "showcases") that allow you to display and enjoy the contents visually (hereinafter also referred to as "showcase conversion"), and users can create their own showcases that are suitable for the contents at a low cost.

[0006] One possible method for attaching the display case door is the simple, rudimentary method described above. However, if a user tries to attach the door to a commercially available shelf using this method, they must carve grooves into the shelf to fit the door, which is not easy for users who do not have specialized tools.

[0007] Furthermore, it is desirable to brightly illuminate the display case so that the contents can be easily viewed, but in the above-mentioned stingy design, the installation of the door and the lighting is not considered to be done using common parts.

[0022] Hereinafter, examples of embodiments of the present invention will be described with reference to the drawings. Note that components common to the following embodiments may be denoted by the same reference numerals as those mentioned above, and their descriptions may be omitted. Furthermore, when referring to the shape, positional relationship, etc., of components, unless otherwise explicitly stated or it is clearly considered otherwise in principle, this includes components that are substantially similar or approximate in shape, etc.

[0023] In each figure of this application, Y represents the vertical direction (+Y is up, -Y is down), X represents the left-right direction perpendicular to the vertical direction (+X is to the right, -X is to the left), and Z represents the depth direction perpendicular to both the vertical and left-right directions (+Z is in the back, -Z is in the front).

[0024] Figure 1 shows an example of a commercially available shelf (hereinafter simply referred to as "shelf") Q, which is a three-tier shelf. The shelf Q only needs to have a rectangular opening, and may have one, two, four or more tiers, and its width and depth are not particularly limited. The shelf Q stores items through the opening into a storage space enclosed by a top plate M, a bottom plate N, and left and right side plates P (left plate Pa, right plate Pb). The illustrated shelf Q has a back plate and an opening only on the front side of the storage space, but it may also lack a back plate and have openings on both the front and back sides of the storage space. The top plate M and bottom plate N are relative; the shelf between the uppermost top plate M and the lowest bottom plate N is the bottom plate N with respect to the shelf directly above it, and the top plate M with respect to the shelf directly below it.

[0025] <Embodiment 1> Figure 2 shows an example of the shelf door kit 9 ​​of Embodiment 1, and includes (a) an example of the door panel 81, (b) an example of the upper dustproof plate 82, (c) an example of the door mounting parts kit 7, and an example of the state in which the door panel 81 and the upper dustproof plate 82 are attached to the shelf Q using these (in use). The center line A in the figure is the center line along the Z direction that divides the shelf Q into left and right halves. Hereinafter, the direction approaching the center line A will be referred to as inward (or inside), and the direction moving away from the center line A will be referred to as outward (or outside).

[0026] <Door Kit> The door kit 9 ​​for this embodiment includes a door panel 81, an upper dustproof plate 82, and a door mounting parts kit 7. If the three-tier shelf Q has an opening only on the front side as shown in the figure, the door kit 9 ​​includes three door panels 81, three upper dustproof plates 82, and three sets of door mounting parts kits 7. If the three-tier shelf Q does not have a back panel and has openings on both the front and back sides, the door kit 9 ​​includes six door panels 81, six upper dustproof plates 82, and six sets of door mounting parts kits 7, which can close both openings. Hereinafter, unless otherwise specified, the description will use a shelf Q with an opening only on the front side as an example.

[0027] <Door plate> The door panel 81 is a transparent, plate-like component (plate material) used to close the opening. The material of the door panel 81 is not particularly limited. The door panel 81 is attached to and removed from the groove on the shelf Q using the door mounting parts kit 7.

[0028] <Upper dustproof plate> The upper dustproof plate 82 is intended to seal the gap between the door panel 81 and the top panel M, preventing dust from entering from above. The upper dustproof plate 82 is, for example, a horizontally elongated plate-shaped member with a substantially uniform thickness, and the material is not particularly limited. The upper dustproof plate 82 is installed in a groove on the shelf Q using the door mounting parts kit 7, so that its upper end is positioned above the upper end of the door panel 81, and is attached so as to be in close contact with the underside of the top panel M.

[0029] <Door mounting parts kit> The door mounting kit 7 is a set of parts that includes multiple components for creating grooves in the shelf Q for mounting the door panel 81 and the upper dustproof plate 82. The door mounting kit 7 includes a pair of top panel groove components 10 that are attached to the top panel M at the left and right corners of the opening, and a pair of bottom panel groove component units 20 that are attached to the bottom panel N at the left and right corners of the opening. In other words, the shelf Q can have grooves for mounting the door panel 81 and the upper dustproof plate 82 installed without having to cut grooves in the shelf itself, thanks to the top panel groove components 10 and bottom panel groove component units 20 that are attached in pairs at the four corners of the opening.

[0030] <Top plate groove component> Figure 3 shows an example of the mounting state (usage state) of the top plate groove component 10 of Embodiment 1, showing (a) the mounting state of the left top plate groove component 10a and (b) the mounting state of the right top plate groove component 10b. Figure 4 is a perspective view showing an example of the top plate groove component 10 of Embodiment 1, observed from above on the right side in the foreground. The top plate groove component 10 is configured such that the left top plate groove component 10a and the right top plate groove component 10b are symmetrical with respect to the center line A when mounted, and the following explanation will mainly use the illustration of the left top plate groove component 10a as an example.

[0031] The top panel groove component 10 has a top panel door groove 15 for fitting the door panel 81 and an upper dustproof groove 16 for fitting the upper dustproof plate 82.

[0032] The top plate groove component 10 is, for example, a block-shaped member having a base 11 on which the top plate door groove 15 and the upper dustproof groove 16 are provided, and a positioning guide 12 extending upward from the base 11. The top plate groove component 10 may be formed integrally by molding using a mold or 3D printing, or the block-shaped member may be formed integrally by cutting, or separately formed parts may be fixed integrally by adhesive or welding.

[0033] The top plate groove component 10 is attached to a predetermined position on the underside of the top plate M using an adhesive means (such as double-sided tape or other adhesive material) via the approximately horizontal upper surface 110 of the base portion 11. The top plate groove component 10 has an outer side surface (the left side for the left top plate groove component 10a, and the right side for the right top plate groove component 10b) that is approximately perpendicular to the upper surface 110, and is attached in a state where the outer side surface is pressed against the inner side surface of the side plate P of the shelf Q to ensure close contact. In other words, the left and right position of the top plate groove component 10 during installation can be determined by pressing its outer side surface against the side plate P.

[0034] The positioning guide 12 is a portion that extends upward from the front end of the base 11 and is used to determine the mounting position in the depth direction. The top plate groove component 10, with the positioning guide 12, has a roughly right-angle corner B2 formed by the upper surface 110 of the base 11 and the back surface (rear side surface) of the positioning guide 12. The shelf Q has a right-angle corner B1 formed by the front surface (front side surface) and the bottom surface of the top plate M. When installing the top plate groove component 10, the positioning guide 12 is pressed against the corner B1 of the shelf Q, and the surface forming the corner B2 is brought into contact with the top plate M, thereby enabling positioning in the depth direction.

[0035] Multiple top panel groove components 10 with different depths may be provided. In some cases, the top panel M of the shelf Q may be deeper and longer from front to back than the bottom panel N. In such cases, a top panel groove component 10 with a longer depth is used so that the door panel 81 can be mounted perpendicularly to the shelf, that is, so that the distance from the rear position of the positioning guide 12 to the front wall surface of the upper dustproof groove 16 is long, and the upper dustproof groove 16 and the top panel door groove 15 are positioned relatively far back. Also, if the top panel M is deeper than the bottom panel N, a top panel groove component 10 with a shorter depth is used so that the door panel 81 can be mounted perpendicularly to the shelf.

[0036] The top door groove 15 is a fitting groove for fitting the door panel 81 in a swivel-type manner, and is provided in the base 11, penetrating its lower surface. The top door groove 15 does not penetrate the upper surface 110 of the base 11, and an upper wall portion of a predetermined thickness is formed between it and the upper surface 110, and has an upper wall surface consisting of the lower surface of the upper wall portion. The depth width of the top door groove 15, that is, the distance between the front wall surface and the back wall surface, is slightly larger than the thickness of the door panel 81. In this embodiment, the top door groove 15 is provided penetrating the left and right sides of the base 11.

[0037] The upper dustproof groove 16 is provided parallel to the top panel door groove 15 on the front side of the top panel door groove 15, and its upper end is above the upper wall surface of the top panel door groove 15. The upper dustproof groove 16 is provided so as to penetrate both the upper surface 110 and the lower surface of the base 11, and does not have an upper wall surface (it is open), and its upper end is above the upper wall surface of the top panel door groove 15. When the upper surface 110 of the base 11 is in close contact with the lower surface of the top panel M, the upper part of the upper dustproof groove 16 is sealed by the lower surface of the top panel M, and the lower surface of the top panel M becomes the upper wall surface. By configuring the upper dustproof groove 16 in this way, the upper dustproof plate 82 can be attached so as to be in close contact with the lower surface of the top panel M. The upper dustproof groove 16 penetrates the side surface of the base 11 on the inside and has an outer wall surface 161 on the outside. The upper dustproof plate 82 is inserted and fixed between the left and right top panel groove parts 10. The upper dustproof plate 82 has, for example, a thickness equal to or slightly greater than the depth of the upper dustproof groove 16, and is secured by friction between its front and back surfaces and the front and rear side walls of the upper dustproof groove 16. The width (length) of the upper dustproof plate 82 in the left-right direction is greater than the distance between the inner sides of the left and right base portions 11.

[0038] <Bottom plate groove component unit> Figure 5 shows an example of the mounting state of the bottom plate groove component unit 20 of Embodiment 1, showing (a) the mounting state of the left bottom plate groove component unit 20 and (b) the mounting state of the right bottom plate groove component unit 20. Figure 6 shows an example of the mounting state of the bottom plate groove component unit 20 of Embodiment 1, showing (a) the mounting state of the left bottom plate groove component unit 20a and (b) the mounting state of the right bottom plate groove component unit 20b. Figure 7 shows an example of the first bottom plate groove component 21 of Embodiment 1, showing (a) an example observed from above on the front right side and (b) an example observed from below on the front left side. Figure 8 shows an example of the second bottom plate groove component 22 of Embodiment 1, showing (a) an example observed from above on the front right side and (b) an example observed from below on the front left side. Figure 9 shows the mounting method of the bottom plate groove component unit 20 of Embodiment 1.

[0039] The bottom plate groove component unit 20 includes a first bottom plate groove component 21 and a second bottom plate groove component 22 positioned behind the first bottom plate groove component 21, forming a bottom plate door groove 24 between it and the first bottom plate groove component 21 for fitting a door plate 81. The bottom plate groove component unit 20 may also include a positioning component 23 for determining the position of the second bottom plate groove component 22. The bottom plate groove component unit 20 may also include a guard component 25 (see Figure 19 below) that is superimposed on the first bottom plate groove component 21. The first bottom plate groove components 21 of the left and right bottom plate groove component units 20 may be symmetrical on both sides as shown in Figure 5, or they may be symmetrical on both sides with respect to the aforementioned center line A as shown in Figure 6. The following explanation will use the symmetrical design as an example.

[0040] As shown in Figure 7, the first bottom plate groove component 21 is a member for preventing the door plate 81 from falling off, and is attached to the upper surface of the bottom plate N at the left and right corners of the opening. The first bottom plate groove component 21 has a base portion 210 and a positioning guide 211 that extends downward from the bottom surface at the front end of the base portion 210.

[0041] The first bottom plate groove component 21 is attached to a predetermined position on the upper surface of the bottom plate N by adhesive means using the substantially horizontal lower surface of the base portion 210. The first bottom plate groove component 21 is attached with both sides (left side and right side) being planes that are substantially perpendicular to the lower surface, and with its outer sides in close contact with the inner sides of the side plates P of the shelf Q. In other words, the left and right position of the first bottom plate groove component 21 during installation can be positioned by pressing its outer sides against the side plates P.

[0042] The positioning guide 211 is for determining the mounting position in the depth direction. The first bottom plate groove component 21, by having the positioning guide 211, has a corner D2 that is approximately right-angled between the lower surface of the base 210 and the back surface of the positioning guide 211. The shelf Q has a right-angled corner D1 formed by the front and top surfaces of the bottom plate N. When mounting the first bottom plate groove component 21, the positioning guide 211 is pressed against the corner D1, and the surface forming the corner D2 is brought into contact with the bottom plate N, thereby enabling positioning in the depth direction.

[0043] Multiple first bottom plate groove components 21 with different depths may be provided. In the case of shelf Q, the top plate M may have a different width in the depth direction from the bottom plate N. In such cases, the first bottom plate groove component 21 can be adjusted so that the door plate 81 can be mounted perpendicularly to the shelf. If the top plate M is longer front to back, a base 210 with a smaller depth should be used, and if the top plate M is shorter front to back, a base 210 with a larger depth should be used. Alternatively, as mentioned above, adjustment may be made using the top plate groove component 10.

[0044] When the bottom plate groove component unit 20 does not include the guard component 25, the height (vertical width) of the base 210 of the first bottom plate groove component 21 is formed to be relatively high so that the door plate 81 does not fall off. When the bottom plate groove component unit 20 includes the guard component 25, the height (vertical width) of the base 210 of the first bottom plate groove component 210 is formed to be relatively low, and the base 210 has a projection 212 that protrudes upward from the upper surface of one of the left and right ends of the base 210, and a notch 213 that is cut out from the other side. With this configuration, the guard component 25 that is placed on top from above can be received without shifting position, and attachment and detachment are also easy.

[0045] As shown in Figure 8, the second bottom plate groove component 22 has a base portion 220 and a door wall portion 221 extending upward from the upper surface at the front end of the base portion 220. The second bottom plate groove component 22 is attached to the rear side at a predetermined distance from the first bottom plate groove component 21 and is a member that forms a bottom plate door groove 24 between itself and the first bottom plate groove component 21 on the upper surface of the bottom plate N. The second bottom plate groove component 22 is attached to a predetermined position on the upper surface of the bottom plate N by adhesive means using the substantially horizontal lower surface of the base portion 220. The second bottom plate groove component 22 is attached with both sides being planes that are substantially perpendicular to the lower surface, and with the outer side in close contact with the inner side of the side plate P of the shelf Q. In other words, the left-right position of the second bottom plate groove component 22 during installation can be positioned by pressing the outer side against the side plate P. The position of the second bottom plate groove component 22 in the depth direction is determined using a positioning component 23. Furthermore, positioning in the depth direction can be done using any method that allows the distance between the first bottom plate groove component 21 and the back surface to be equal to the width of the top plate door groove 15, and a ruler or gauge may be used.

[0046] As shown in Figure 9(b), the positioning component 23 is dedicated to determining the position in the depth direction when attaching the second bottom plate groove component 22. The positioning component 23 has a base portion 230 and a first spacer 231 extending downward from the lower surface of the base portion 230. The depth width of the first spacer 231 is the same as the width of the top plate door groove 15. The first spacer 231 may be configured as a single rectangular parallelepiped extending in the left-right direction, but from the viewpoint of operability (ease of attachment and detachment), it is preferably configured as a pair of cylindrical shapes as shown in the figure.

[0047] When attaching the bottom plate groove component unit 20 to the bottom plate N, as shown in Figure 9(a), the first bottom plate groove component 21 is positioned using the positioning guide 211 and attached to the upper surface of the bottom plate N. Then, as shown in Figure 9(b), the first spacer 231 of the positioning component 23 is pressed against the back surface of the first bottom plate groove component 21 and placed on the upper surface of the bottom plate N. By pressing the door wall portion 221 of the second bottom plate groove component 22 against the first spacer 231, the position of the second bottom plate groove component 22 is determined, and it can then be attached to that position. As a result, as shown in Figures 5 and 6, the bottom plate door groove 24 is formed by the back surface of the first bottom plate groove component 21, the upper surface of the bottom plate N, and the front surface of the door wall portion 221 of the second bottom plate groove component 22.

[0048] <Handle parts> Figure 10 shows an example of the handle component 31 of Embodiment 1, (a) an example viewed from above on the front right side, (b) an example viewed from below on the front left side, and (c) an example showing how to attach it to the door panel 81. The door mounting component kit 7 may include a pair of handle components 31, although this is not particularly limited.

[0049] The handle component 31, as an example, has a handle 310, a base portion 311 on the rear side of the handle 310, and a roughly U-shaped connecting portion 312. The handle component 31 has the base portion 311 and the connecting portion 312 facing each other, forming a groove E between them that allows the door panel 81 to be inserted from the inside. As shown in the figure, by attaching one handle component 31 from one side of the door panel 81 and the other handle component 31 from the other side, a pair of handles 310 can be installed on the door panel 81. The handle component 31 has a groove E with a depth width narrower than the thickness of the door panel 81, and is locked to the door panel 81 by frictional force. The handle component 31 does not require drilling holes in the door panel 81 for attachment and is easy to attach and detach. On the other hand, in the illustrated handle component 31, a portion of the connecting portion 312 is located outside the door panel 81, which creates a gap between the door panel 81 and the side panel P. Therefore, in this embodiment, in order to avoid this gap, it is preferable that the handle component 31 does not have a connecting portion 312 and is attached to the door panel 81 using adhesive means or the like with a base portion 311, or that one of the magnet and magnetic material is installed on the back of the door panel 81 and the other is installed on the base portion 311, sandwiching the door panel 81 from the front and back. The handle component 31 may also be fixed to the door panel 81 with screws or the like by pre-making holes in the door panel 81.

[0050] <How to install the door kit> First, the left and right top plate groove components 10 are positioned using the positioning guide 12 and attached to the underside of the top plate M at the left and right corners of the opening using adhesive means, as shown in Figure 3. Note that adhesive means such as adhesive material or glue should be attached to the upper surface of the base 11 in advance. When attaching the left and right top plate groove components 10, it is desirable to avoid blocking the upper part of the upper dustproof groove 16 with adhesive means such as adhesive material or glue.

[0051] The top panel groove component 10 can be attached to the top panel M in this way to create the top panel door groove 15, requiring no tools, making installation very easy and highly versatile. Furthermore, because the top panel groove component 10 has a positioning guide 12, positioning is extremely easy.

[0052] Next, the left and right first bottom plate groove parts 21 are positioned using the positioning guide 211 and attached to the upper surface of the bottom plate N at the left and right corners of the opening using adhesive means, as shown in Figure 9(a). Note that adhesive means such as adhesive material or adhesive agent are attached to the lower surface of the base 210 in advance. Then, the left and right second bottom plate groove parts 22 are positioned using the positioning part 23 and attached to the upper surface of the bottom plate N using adhesive means, as shown in Figure 9(b). Note that adhesive means such as adhesive material or adhesive agent are attached to the lower surface of the base 220 in advance.

[0053] The bottom plate groove component unit 20 can be attached to the bottom plate N in this way to create a bottom plate door groove 24, requiring no tools, making installation very easy and highly versatile. Furthermore, it has a positioning guide 211 and a positioning component 23, making positioning easy as well. The bottom plate groove component unit 20 allows the lower end of the door plate 81 to directly contact the bottom plate N (without any parts in between), eliminating the gap between the door plate 81 and the bottom plate N due to the weight of the door plate 81, thus preventing dust from entering.

[0054] Next, the upper dustproof plate 82 is fitted into the upper dustproof groove 16 and made to be in close contact with the underside of the top plate M. The top plate groove component 10 is equipped with a plug-in (snap-in) upper dustproof groove 16 along with the top plate door groove 15, so it can be installed easily without the need for tools.

[0055] Finally, the door panel 81 is inserted into the top door groove 15 by lifting its upper end, and then the lower end is inserted into the bottom door groove 24 and fitted in a snap-fit ​​manner to close the opening and complete the installation. Because the door kit 9 ​​is installed in this snap-fit ​​manner using the top groove component 10 and the bottom groove component unit 20, it has improved dustproof performance compared to single-opening, double-opening, or top-opening configurations.

[0056] If the door mounting kit 7 includes handle parts 31, attach a pair of handle parts 31 to the door panel 81 before installing the door panel 81. Installing the handle parts 31 improves the ease of installation of the door panel 81.

[0057] <Embodiment 2> Figure 11 shows an example of the shelf door kit 9 ​​of Embodiment 2, and (a) an example of the door panel 81, (b) an example of the upper dustproof plate 82, (c) an example of a pair of side dustproof plates 83, (d) an example of the door mounting parts kit 7 and an example of the state in which the door panel 81, upper dustproof plate 82 and side dustproof plates 83 are attached to the shelf Q using this kit (in use). The door kit 9 ​​of Embodiment 2 may also include a lighting panel 84, and Figure 12 shows an example of this. Hereinafter, Embodiment 2 will be described, with common components with Embodiment 1 omitted as appropriate, and the differences will be the focus of the explanation.

[0058] <Door Kit> The door kit 9 ​​in this embodiment includes a door panel 81, an upper dustproof plate 82, a pair of side dustproof plates 83, and a door mounting parts kit 7. The door kit 9 ​​in this embodiment may also include a lighting plate 84 as shown in Figure 12. The door panel 81 and the upper dustproof plate 82 are the same as in Embodiment 1 above, and their description is omitted here.

[0059] <Side dustproof plate> The horizontal dustproof plates 83 are for preventing dust from entering between the door panel 81 and the side panel P, and are provided in pairs and attached to the left and right sides of the opening. The material of the horizontal dustproof plates 83 is not particularly limited, and they are vertically elongated plate-shaped members with a substantially uniform thickness. The horizontal dustproof plates 83 are attached to the grooves installed on the shelf Q using the door mounting parts kit 7, so that their side ends are positioned laterally than the side ends of the door panel 81, and are attached so as to be in close contact with the inner side surface of the side panel P.

[0060] <Lighting panel> The lighting panel 84 is a plate-shaped component with lighting attached to illuminate the storage space. The lighting panel 84 is, for example, an LED panel (with an LED tape with a power cord attached). The lighting panel 84 is installed in a groove on the shelf Q using the door mounting parts kit 7, at a position further back than the door panel 81.

[0061] <Door mounting parts kit> The door mounting kit 7 in this embodiment is a set of parts including multiple parts for providing grooves in the shelf Q for attaching the door panel 81, the upper dustproof plate 82, and the side dustproof plate 83. If the door kit 9 ​​includes a lighting panel 84, it may further include a corresponding configuration or part. The door mounting kit 7 in this embodiment includes a pair of top panel groove parts 10 that are attached to the top panel M at the left and right corners of the opening, and a pair of bottom panel groove part units 20 that are attached to the bottom panel N at the left and right corners of the opening. The door mounting kit 7 in this embodiment may also include a pair of handle parts 31, similar to Embodiment 1.

[0062] <Top plate groove component> Figures 13 to 15 show examples of the top plate groove component 10 of Embodiment 2. Figure 13(a) shows an example of the left top plate groove component 10a observed from above on the front right side, Figure 13(b) shows an example of it observed from below on the front left side, Figure 14(a) shows an example of it observed from below on the back right side, and Figure 14(b) shows an example of it observed from above on the back left side. Figure 15(a) shows an example of the right top plate groove component 10b observed from above on the front right side, and Figure 15(b) shows an example of it observed from below on the front left side. The top plate groove component 10 is configured such that the left top plate groove component 10a and the right top plate groove component 10b are symmetrical with respect to the aforementioned center line A when installed, and the following explanation will use the illustration of the left top plate groove component 10a as an example.

[0063] The top panel groove component 10 has a top panel door groove 15 for fitting the door panel 81, an upper dustproof groove 16 for fitting the upper dustproof plate 82, and a side dustproof groove 17 for fitting the side dustproof plate 83. If the door kit 9 ​​includes a lighting plate 84, it further has a lighting groove 18 for fitting the lighting plate 84.

[0064] The top door groove 15 is the same as in Embodiment 1, except that it penetrates the side of the base 11 on the inside but has an outer wall surface on the outside, so a detailed explanation is omitted. The upper dustproof groove 16 is the same as in Embodiment 1, so a detailed explanation is omitted.

[0065] The lateral dustproof groove 17 is a groove for attaching the lateral dustproof plate 83, and its side end is located outside the top door groove 15. The lateral dustproof groove 17 is provided on the back side of the top door groove 15 so as to penetrate the lower surface of the base 11, and its wall surfaces are approximately parallel to the top door groove 15. The lateral dustproof groove 17 is provided on the base 11 so as to penetrate the outer surface, has no outer wall surface (is open), and its side end is located outside the top door groove 15. In other words, in the mounting state where the outer surface of the base 11 is in close contact with the inner surface of the side plate P, the outside of the lateral dustproof groove 17 is sealed by the inner surface of the side plate P, and the inner surface of the side plate P becomes the outer wall surface. By configuring the lateral dustproof groove 17 in this way, the lateral dustproof plate 83 can be attached so as to be in close contact with the inner surface of the side plate P. In this embodiment, the top plate groove component 10 can tightly seal the upper dustproof plate 82 and the side dustproof plate 83 with the top plate M and side plate P, eliminating any gaps, and overlapping with the door plate 81 in the depth direction, thereby preventing dust from entering and further improving dustproof performance. The side dustproof plate 83 is inserted and fixed between the side dustproof groove 17 and the side dustproof groove 223 of the second bottom plate groove component 22, which will be described later. For example, the thickness of the side dustproof plate 83 is equal to or slightly larger than the depth width of the side dustproof grooves 17 and 223, and it is locked in place by frictional force between the front and back surfaces of the side dustproof grooves and the front and rear side walls. The vertical width (length) of the side dustproof plate 83 is greater than the distance between the lower surface of the base 11 and the upper surface of the door wall portion 221 and the side dustproof wall portion 222 of the second bottom plate groove component 22, which will be described later.

[0066] The lighting groove 18 is provided at the back of the top door groove 15, at an angle to the top door groove 15. The top groove component 10, by providing the lighting groove 18 inclined and inclining the mounting angle of the lighting plate 84, can effectively illuminate the shelf Q from the front to the back, improving its aesthetic appeal. The lighting groove 18 is provided by penetrating the lower surface of the base 11 so that the lighting plate 84 can be inserted from below. In this embodiment, the top groove component 10, by providing the lighting groove 18 in this way, can be mounted using the same components as the door plate 81, without the need for tools, and LED or other lighting can be easily and inexpensively added to a general-purpose commercially available shelf.

[0067] The top plate groove component 10 in this embodiment preferably has a fixing portion 13 on the inside of the base portion 11. The fixing portion 13 is a part provided on the inner side surface of the base portion 11 so as to extend inward. The fixing portion 13 has, for example, a fixing hole 131 that penetrates vertically through approximately in the center. The fixing hole 131 is, for example, a screw hole with female threads on its inner circumferential surface or a through hole without threads. The top plate groove component 10 is attached to the lower surface of the top plate M by adhesive means using the upper surface of the base portion 11, but if it cannot be attached by adhesive means or if a more secure fixation is desired, it can be attached to the top plate M using screws or the like with the fixing hole 131.

[0068] When the door kit 9 ​​includes a lighting panel 84, the base portion 11 of this embodiment is preferably formed in a stepped shape, having a first portion 111 and a second portion 112 that is smaller in vertical width (vertical thickness) than the first portion 111. This forms a wiring section C for arranging the power lines of the lighting panel 84 on the outer surface of the first portion 111 and the upper surface of the second portion 112. When installed, this wiring section C, the lower surface of the top plate M, and the inner surface of the side plate P form a passage leading from the opening to the back, allowing the power lines to be easily pulled out. The wiring section C is preferably provided in a shape that is cut to the minimum necessary depth so as not to interfere with other members (for example, dowels or pins for fixing the shelf board to the shelf Q) when pulling the power lines out from the back of the housing to the outside, and also not to interfere with the wiring components of the lighting panel 84. The top plate groove component 10 of this embodiment, by having a wiring section C, makes it easy to wire the lighting panel 84. The top plate groove component 10 may have a wiring hook on the back of the base portion 11, similar to the top plate groove intermediate component 40 described later. The wiring hook is a hook-shaped part used to hook the wiring or terminal portion of the lighting board 84. If the base portion 11 has a wiring portion C, the wiring hook is provided on the back of the first portion 111. The wiring hook may also be provided on the back of the second portion 112, or on both.

[0069] The top plate groove component 10 in this embodiment can be positioned using the outer side surface (outer side surface of the second part 112) and the positioning guide 12, and attached to the underside of the top plate M using adhesive means with the upper surface of the base 11 (upper surface of the first part 111), similar to Embodiment 1. Alternatively, it may be positioned similarly and fixed with screws or the like using the fixing part 13. The top plate groove component 10 is easy to install because it can be fixed with screws using the fixing part 13, requiring only a screwdriver.

[0070] <Bottom plate groove component unit> Figure 16 shows an example of the mounting state of the bottom plate groove component unit 20 of Embodiment 2, showing (a) the mounting state of the left bottom plate groove component unit 20 and (b) the mounting state of the right bottom plate groove component unit 20. Figure 17 shows an example of the second bottom plate groove component 22 of Embodiment 2, showing (a) an example observed from above on the front right side and (b) an example observed from below on the front left side. Figure 18 shows an example of the positioning component 23 of Embodiment 2, showing (a) an example observed from above on the front right side and (b) an example observed from below on the front left side. Figure 19 shows an example of the guard component 25, showing (a) an example observed from above on the front right side and (b) an example observed from below on the back right side.

[0071] The bottom plate groove component unit 20 includes a first bottom plate groove component 21, a second bottom plate groove component 22 positioned behind the first bottom plate groove component 21 and forming a bottom plate door groove 24 for fitting a door plate 81 between itself and the first bottom plate groove component 21, and a positioning component 23 for determining the position of the second bottom plate groove component 22. The bottom plate groove component unit 20 may also include a guard component 25 that is superimposed on the first bottom plate groove component 21. The first bottom plate groove components 21 of the left and right bottom plate groove component units 20 may be symmetrical on the left and right sides as shown in Figure 16, or they may be symmetrical on the left and right sides with respect to the aforementioned center line A. The first bottom plate groove component 21 is the same as in Embodiment 1, and its description is omitted here.

[0072] As shown in Figure 17, the second bottom plate groove component 22 has a base portion 220, a door wall portion 221 extending upward from the upper surface at the front end of the base portion 220, and a lateral dustproof wall portion 222 extending upward from the upper surface of the base portion 220 at the rear side of the door wall portion 221. The base portion 220 and the door wall portion 221 are the same as in Embodiment 1, and their description is omitted here.

[0073] The bottom plate groove component unit 20 has a lateral dustproof wall portion 222, and is equipped with a lateral dustproof groove 223 formed by the back surface of the door wall portion 221, the top surface of the base portion 220, and the front surface of the lateral dustproof wall portion 222. The lateral dustproof plate 83 is attached to the opening with its longitudinal direction vertical using the lateral dustproof groove 17 of the top plate groove component 10 and this lateral dustproof groove 223. The lateral dustproof groove 223 has the same depth width as the lateral dustproof groove 17. The lateral dustproof groove 223 is a groove that penetrates from left to right and does not have a side wall surface, allowing the lateral dustproof plate 83 to be attached in close contact with the side plate P.

[0074] As shown in Figure 18, the positioning component 23 has a base 230, a first spacer 231 extending downward from the lower surface of the base 230, and a second spacer 232 extending downward from the lower surface of the base 230 on the rear side of the first spacer 231. The base 230 and the first spacer 231 are the same as in Embodiment 1 and will not be described here.

[0075] The second spacer 232 has a depth width that is approximately the same as the width of the lateral dustproof groove 223. The distance between the second spacer 232 and the first spacer 231 is approximately the same as the front-to-back width of the door wall 221. The second spacer 232 may be configured as a single rectangular parallelepiped extending in the left-right direction, but from the viewpoint of operability (easy insertion and removal), it is preferably configured as a pair of cylindrical shapes as shown in the figure.

[0076] In this embodiment, the positioning component 23 allows for easy determination of the depth-direction position of the second bottom plate groove component 22 by attaching the first bottom plate groove component 21, inserting the second spacer 232 into the lateral dustproof groove 223 of the second bottom plate groove component 22, and pressing the front end of the first spacer 231 against the back surface of the first bottom plate groove component 21. The bottom plate door groove 24 is formed by the back surface of the first bottom plate groove component 21, the top surface of the bottom plate N, and the front surface of the second bottom plate groove component 22.

[0077] <Guard parts> The guard component 25 is designed to prevent the door panel 81 from falling off due to earthquakes or other events. It is attached to the upper surface of the first bottom plate groove component 21 to increase its height. If the height required to prevent the door panel from falling off is achieved using only one component of the first bottom plate groove component 21, the vertical width of the door panel 81 would need to be reduced by that amount to allow for the door panel 81 to be attached and detached in a swivel-type manner. Therefore, by using a two-part configuration consisting of the first bottom plate groove component 21 and the guard component 25, the guard component 25 can be removed to lower the door panel when it is attached or detached, thereby increasing the vertical width of the door panel 81 and maximizing the effective viewing area.

[0078] As shown in Figure 19, the guard part 25 has a base 250, a finger rest portion 251 cut out from the back and top surfaces of the base 250, a notch 252 cut out from one side and the bottom surface of the left and right ends of the base 210, and a projection 253 projecting downward from the other bottom surface. The presence of the finger rest portion 251 of the guard part 25 ensures that there is space to insert a finger between the guard part 25 and the door panel 81 when installed, thereby improving operability. The guard part 25 can be easily attached to the first bottom plate groove part 21 without misalignment by fitting the notch 252 with the projection 212 of the first bottom plate groove part 21 and fitting the projection 253 with the notch 213 of the first bottom plate groove part 21.

[0079] <Wiring cover component> Figure 20 shows an example of the wiring cover component 32 of Embodiment 2, (a) an example of the left wiring cover component 32 observed from above on the front right side, and (b) an example of the left wiring cover component 32 observed from below on the front left side. Figure 21 shows an example of the wiring cover component 33 of Embodiment 2, (a) an example of the right wiring cover component 33 observed from above on the front right side, and (b) an example of the right wiring cover component 33 observed from below on the front left side. Note that the wiring cover components are configured to be symmetrical with respect to the aforementioned center line A when installed, and here, one example is illustrated and explained.

[0080] The wiring cover component is used to cover the wiring section C when the top panel groove component 10 has one. On the side where wiring is not required, wiring cover component 32 is used to completely cover the wiring section C, while on the side where wiring is required, wiring cover component 33 is used to cover the wiring section C, leaving a space for the power lines, thereby preventing dust from entering the wiring section C. If wiring is not required, wiring cover component 32 is installed on both sides.

[0081] The wiring cover component 32 has an insertion portion 321 for insertion into the wiring section C and a contact portion 322 provided on the front side of the insertion portion 321. The wiring cover component 33 has an insertion portion 331 for insertion into the wiring section C and a contact portion 332 provided on the front side of the insertion portion 331. The wiring cover component 33 further has a notched relief portion 333 provided on the insertion portion 331 and the contact portion 332 so as to extend in the depth direction. By providing the relief portion 333, the wiring cover component 33 creates a space for power line wiring between the top plate M and the side plate P.

[0082] <How to install the door kit> First, as shown in Figure 22, the left and right top plate groove parts 10 are positioned using the positioning guide 12 and attached to the underside of the top plate M at the left and right corners of the opening using adhesive means. The adhesive means, such as adhesive material or glue, is attached to the upper surface of the base 11 in advance. When attaching the left and right top plate groove parts 10, it is desirable to avoid blocking the upper part of the upper dustproof groove 16 with the adhesive means, such as adhesive material or glue.

[0083] Next, as shown in Figure 23, the left and right first bottom plate groove parts 21 are positioned using the positioning guide 211 and attached to the upper surface of the bottom plate N at the left and right corners of the opening using adhesive means. Then, the left and right second bottom plate groove parts 22 are positioned using the positioning part 23 and attached to the upper surface of the bottom plate N using adhesive means. Note that adhesive means such as adhesive material or adhesive agent are attached to the lower surface of the base 210 and the lower surface of the base 220 in advance.

[0084] Next, as shown in Figure 24, the upper dustproof plate 82 is fitted into the upper dustproof groove 16 and made to be in close contact with the lower surface of the top plate M.

[0085] Next, as shown in Figure 25, the lateral dustproof plate 83 is fitted into the lateral dustproof groove 17 and the lateral dustproof groove 223 and made to be in close contact with the inner side surface of the side plate P.

[0086] Next, as shown in Figure 26, if you want to run a power line (not shown) to the left side of shelf Q, for example, insert the lighting panel 84 with the power line on the left. Attach an LED tape with a power line to the lighting panel 84 beforehand. This completes the installation of the dustproof panels 82, 83 and the lighting panel 84. Figure 26(b) shows the horizontal dustproof panel 83 and the horizontal dustproof groove 17, with the side panel Pb omitted. As shown, since the horizontal dustproof groove 17 does not have an outer wall surface, the horizontal dustproof panel 83 can be placed in close contact with the side panel P.

[0087] Next, when routing the power line to the left side, the power line (not shown) is routed to the outside from the wiring section C of the left top panel groove component 10 shown in Figure 27(a), and the left wiring cover component 33 is attached to the wiring section C, using the avoidance section 333 shown in Figure 27(b) to avoid the power line. As shown in Figure 27(c), the right wiring cover component 32 is attached to the wiring section C of the right top panel groove component 10.

[0088] Next, as shown in Figure 28, a pair of handle parts 31 are attached to the door panel 81, and the door panel 81 is fitted into place using a snap-fit ​​mechanism to close the opening of shelf Q. At this time, the horizontal dustproof groove 17 is located behind the top door groove 15, and the door panel 81 is attached in front, so the previously attached horizontal dustproof plate 83 does not get in the way. Also, the handle parts 31 do not interfere with the horizontal dustproof plate 83. Furthermore, even when using the handle parts 31 shown in Figure 10, the horizontal dustproof plate 83 overlaps at the back, so dust can be prevented from entering.

[0089] Next, as shown in Figure 29, the guard component 25 is attached to the first bottom plate groove component 21 to complete the installation of the door kit 9.

[0090] As described above, the door kit 9 ​​allows for the creation of a showcase with dustproof performance and LED lighting using existing shelves. The door kit 9 ​​prevents dust from entering by providing grooves for mounting the dustproof plate on the mounting parts for creating door grooves on the shelves, thereby ensuring a tight fit between the dustproof plate and the top and side panels, eliminating gaps, and overlapping the dustproof plate with the door panel. In addition, by making the lower edge of the door panel directly contact the bottom panel, the weight of the door panel eliminates the gap with the bottom panel, preventing dust from entering. Furthermore, dust can be prevented from entering by sealing the wiring section C, which is the power line wiring hole.

[0091] Door Kit 9 allows for the easy and inexpensive conversion of shelves of any size into display cases. First, it is easy and inexpensive to adjust the size to fit the shelf opening. Specifically, the size adjustment to fit the opening is determined only by the flat board material (1 door panel, 3 dustproof panels, 1 lighting panel), and because it uses general-purpose materials and requires few parts, processing (size adjustment) is easy and inexpensive. Second, the mounting parts for each board material (3 dustproof panels, 1 door panel) are grooved, allowing for dimensional leeway and a large tolerance for error, making size adjustment easy. Furthermore, if there is a difference in depth between the top and bottom panels, this can be addressed by using top and bottom panel groove parts with different depths to prevent the vertically standing door panel and dustproof panels from becoming slanted. Furthermore, if the shelf width (left-right width) is large (approximately 70 cm or more), the increased weight of the upper dustproof plate and lighting plate may cause the top plate groove component to fail to hold, potentially leading to its fall. However, this can be addressed by using the top plate groove relay component described in Embodiment 3 below, which divides the plate material and distributes the load.

[0092] Door Kit 9 is inexpensive. The only special components are the mounting parts attached to the four corners; the rest of the surface area is mostly flat panels, thus keeping costs down. Furthermore, multiple functions (door panel, top and side dustproof panels, lighting panel, and power wiring section) are integrated into a single top panel groove component, reducing the number of parts and thus lowering costs. Additionally, the use of a hinged door panel eliminates the need for moving parts like those found in flip-up or hinged doors, further reducing costs.

[0093] Door kit 9 ​​can be assembled without tools. Specifically, the dustproof plate and lighting plate are snap-fit, so no tools are required. The door panel is snap-fit, so no tools are required. For the door mounting parts kit, the groove parts (top plate groove part and 1st and 2nd bottom plate groove parts) are attached using adhesive, so no tools are required. Screws can also be used, but even then, only a screwdriver is needed for installation. The handle parts are clamp-fit, so no tools are required.

[0094] Door kit 9 ​​is easy to position. The top plate groove component can be positioned in depth using a positioning guide, and in width (left-right position) by pressing it against the side plate. The first bottom plate groove component can be positioned in depth using a positioning guide, and in width by pressing it against the side plate. The second bottom plate groove component can be positioned in depth using a positioning component, and in width by pressing it against the side plate.

[0095] Door Kit 9 offers superior aesthetic appeal. By using a single, seamless door panel, it eliminates the seams found in sliding doors, improving the visibility of the contents. Furthermore, maximizing the door panel size maximizes the effective viewing area. First, minimizing the size of the dustproof panel maximizes the effective viewing area. Second, if the first bottom plate groove component is made to a height that prevents the door panel from falling out using a single component, the height of the seamless door panel would need to be shortened by that height for attachment and detachment. However, by designing it as a two-part system with a guard component, the guard component can be removed to lower the door panel when attaching or detaching it, allowing the door panel to be raised and the effective viewing area to be maximized. In addition, the top plate groove component allows for easy and inexpensive installation of LED or other lighting on general-purpose shelves. Moreover, by angling the mounting groove for the lighting panel, lighting can be effectively directed from the front to the back of the shelf, improving aesthetic appeal.

[0096] Door Kit 9 achieves both safety and ease of use. By designing the first bottom plate groove component and guard component separately, the guard component can be removed to facilitate attachment and detachment of the door panel, and the guard component can be attached during normal operation to prevent the door from falling off due to earthquakes or other events.

[0097] <Embodiment 3> Figure 30 is a perspective view showing an example of the top plate groove connecting part 40 of Embodiment 3, (a) an example observed from above on the front right side, and (b) an example observed from below on the back right side. In this embodiment, the door mounting parts kit 7 of Embodiment 1 or the door mounting parts kit 7 of Embodiment 2 further includes the top plate groove connecting part 40. The door kit 9 ​​of this embodiment includes one pair of upper dustproof plates 82 and one pair of lighting plates 84.

[0098] In the previously described embodiment, if the width (left-right width) of the shelf is large, the increased weight of the upper dustproof plate 82 and the lighting plate 84 may cause the top plate groove components 10 at the left and right corners to be unable to hold them, potentially leading to them falling. In this embodiment, a top plate groove connecting component 40 is used to distribute the load received by the left and right top plate groove components 10. The top plate groove connecting component 40 is used, for example, by attaching it to the lower surface of the center in the left-right direction of the top plate M when the width of the shelf is 70 cm or more.

[0099] As an example, the top panel groove connecting part 40 is formed symmetrically with respect to a center line F along the Z-direction that divides it into left and right halves. The top panel groove connecting part 40 has a top panel door groove 45 for fitting the door panel 81, and a pair of left and right upper dustproof grooves 46 for fitting the upper dustproof plate 82. If the door kit 9 ​​includes a lighting plate 84, it has a pair of left and right lighting grooves 48 for fitting the lighting plate 84. The pair of upper dustproof grooves 46 and the pair of lighting grooves 48 are formed symmetrically with respect to the center line F. The pair of upper dustproof plates 82 are fitted into the pair of upper dustproof grooves 46 and the upper dustproof grooves 16 of the left and right top panel groove parts 10, respectively, and the pair of lighting plates 84 are fitted into the pair of lighting grooves 48 and the lighting grooves 18 of the left and right top panel groove parts 10, respectively.
