Summary of the Invention

Problems to be Solved by the Invention

[0005] The engagement holes to which the shelf receiver is not attached are in a state of being exposed on the inner surface of the support member. Therefore, there is a possibility that foreign matter may enter the support member through the engagement holes.

[0006] An aspect of the present invention aims to provide furniture that can prevent foreign matter from entering the support member through the engagement holes.

Means for Solving the Problems

[0007] A fixture according to one aspect of the present invention comprises two support members spaced apart and with opposing surfaces facing each other, the support members having a first main plate having the opposing surfaces and a second main plate positioned with an internal space between it and the first main plate, the first main plate having a plurality of engagement holes, the support member being provided with an entry restriction structure that restricts the entry of foreign matter from the engagement holes into the internal space, the entry restriction structure having a restricting portion positioned in the internal space, the restricting portion overlapping at least a portion of the engagement holes when viewed from a direction perpendicular to the first main plate.

[0008] With this configuration, the restricting part can prevent foreign matter from entering the inside of the support member through the engagement hole.

[0009] The fixture further comprises at least one shelf on which articles can be placed on its upper surface, and a shelf support that is detachably attached to the support member and supports the shelf, wherein the shelf support preferably has an engaging portion that selectively engages with the engaging hole and a shelf support portion that supports the shelf. With this configuration, items can be stored on the shelves.

[0010] Preferably, the entry restriction structure includes a mounting plate attached to the first main plate or the second main plate, and a connecting portion that connects the restriction portion and the mounting plate. This configuration allows the restricting portion to be stably installed on the support member. Therefore, the effect of restricting the entry of foreign matter through the engagement hole can be enhanced.

[0011] In a plane parallel to the opposing surface, the direction perpendicular to the extending direction of the support member is the front-rear direction, and the restricting portion and the mounting plate may extend from the connecting portion to the same side, either the front or the rear. With this configuration, since the restricting portion and the mounting plate extend to the same side, the dimensions of the entry restriction structure in the front-to-back direction can be reduced. Therefore, an entry restriction structure can be provided even when the internal space of the support member is small.

[0012] The direction perpendicular to the extending direction of the support member within the plane parallel to the opposing surface is the front-rear direction, and the restricting portion and the mounting plate may extend from the connecting portion to different sides, either the front or the rear. This configuration allows the mounting plate to be positioned offset from the engagement hole in the front-rear direction. Therefore, there are fewer constraints on the shape and size of the mounting plate. Consequently, the restricting portion can be stably installed on the support member.

[0013] The entry restriction structure may have two mounting plates and two connecting parts, wherein one side edge of the restriction part is connected to the first mounting plate of the two mounting plates via the first connecting part of the two connecting parts, and the other side edge of the restriction part is connected to the second mounting plate of the two mounting plates via the second connecting part of the two connecting parts. With this configuration, the restricting portion is connected to the first and second mounting plates at both side edges, respectively, so that the restricting portion can be stably installed on the support member.

[0014] Preferably, the restricting portion extends in the direction of the alignment of the plurality of engagement holes and is arranged to overlap the plurality of engagement holes. This configuration allows for a reduction in the number of parts and a simplification of the internal structure of the support members.

[0015] The distance between the restricting portion and the opposing surface is preferably 10 mm or less. This configuration enhances the effect of restricting foreign matter from entering the internal space through the engagement hole. [Effects of the Invention]

[0018] Hereinafter, the furniture according to the embodiment will be described based on the drawings.

[0019] Figure 1 is a perspective view of the article storage unit 100 according to the embodiment. Figure 2 is a perspective view of a part of the article storage unit 100. Figure 3 is a perspective view of the article storage unit 100 with the shelf board 1 removed. Figures 4 and 5 are perspective views of the shelf support 7. Figure 6 is a perspective view of a part of the article storage unit 100. Figure 7 is a perspective view showing the internal structure of the support member 2. Figure 8 is a perspective view of the entry restriction member 8 attached to the first main plate 21. Figure 9 is an exploded perspective view of the entry restriction member 8 and the first main plate 21. Figure 10 is a perspective view of the entry restriction member 8 viewed from a different direction than in Figure 9. Figure 11 is a cross-sectional view of the support member 2. Figure 11 shows the II cross-section of Figure 6. Figure 12 is a cross-sectional view of the entry restriction member 8.

[0020] In the following explanation, the XYZ coordinate system, which is a Cartesian coordinate system, may be used. The X direction is the direction in which the two support members are aligned (width direction X). The Z direction is the direction in which the upper and lower connecting members are aligned (up and down direction Z). The Y direction is perpendicular to the X and Z directions (front and back direction Y). The upper connecting member is above the lower connecting member. The opposite side of the upper side is the lower side.

[0021] One direction in the front-to-back Y direction (-Y side) is the front. The opposite side of the front (+Y side) is the rear. The plane defined by the X and Y directions is the XY plane. The plane defined by the X and Z directions is the XZ plane. The plane defined by the Y and Z directions is the YZ plane.

[0022] As shown in Figure 1, the item storage unit 100 comprises at least one or more shelves 1, two support members 2, an upper connecting member 3, a lower connecting member 4, a shelf support 7 (see Figure 3), and an entry restriction member 8 (see Figure 7). The item storage unit 100 is, for example, a shoe locker for storing shoes. The item storage unit 100 is an example of a "fixture".

[0023] The space enclosed by the two support members 2, the upper connecting member 3, and the lower connecting member 4 is a storage space S1 for storing an item G1. The storage space S1 is open in the front-to-back direction Y. The two support members 2, the upper connecting member 3, and the lower connecting member 4 constitute a frame 6.

[0024] The shelf board 1 is formed in a plate shape that follows the XY plane. The upper surface 1a of the shelf board 1 is a mounting area 1b on which items can be placed. The direction connecting the two ends of the shelf board 1 in the width direction X is the first direction. The first direction is parallel to the X direction. The direction perpendicular to the width direction X (first direction) in the plane parallel to the upper surface 1a of the shelf board 1 (in the XY plane) is the second direction. The second direction is parallel to the front-to-back direction Y.

[0025] Shelf board 1 is installed in the storage space S1. In Figure 1, items G1 such as shoes are placed on shelf board 1. Shelf board 1 is formed from a plate material made of, for example, metal or resin.

[0026] Multiple shelves 1 are arranged in a line in the vertical direction Z, with spacing between them in the vertical direction Z. Each set of shelves 1 includes multiple main shelves 11 (first shelves) and multiple sub-shelves 12 (second shelves). The main shelves 11 have a larger dimension in the front-to-back direction Y than the sub-shelves 12. The main shelves 11 and sub-shelves 12 are arranged alternately in the vertical direction Z.

[0027] The upper connecting member 3 connects the upper parts of the two support members 2. The upper connecting member 3 is formed in a plate shape parallel to the XY plane. The upper connecting member 3 is, for example, rectangular when viewed from the vertical direction Z. The upper connecting member 3 is, for example, rectangular with a long side along the width direction X.

[0028] The lower connecting member 4 connects the lower parts of the two support members 2. The lower connecting member 4 is formed in the shape of a long plate extending in the width direction X. The lower connecting member 4 is formed in the shape of a plate parallel to the XZ plane. A partition plate 5 is provided on the shelf board 1. The partition plate 5 is formed at the rear or front end of the shelf board 1, extending along its entire length in the width direction X. The partition plate 5 extends in the width direction X. The partition plate 5 can restrict the movement of items G1 placed on the shelf board 1 and prevent them from falling off the shelf board 1.

[0029] Support member 2 is formed in a plate shape parallel to the YZ plane. Support member 2 is, for example, rectangular when viewed from the width direction X. Support member 2 is, for example, rectangular with a longer side along the vertical direction Z. Support member 2 extends in the vertical direction Z. Two support members 2 are provided spaced apart in the width direction X. The two support members 2 support both ends of the shelf board 1.

[0030] As shown in Figures 2 and 6, the support member 2 comprises a first main plate 21 (see Figure 2) and a second main plate 22 (see Figure 6). The second main plate 22 is located on the outside of the first main plate 21 (opposite side from the storage space S1). The second main plate 22 is located at a position away from the first main plate 21. The second main plate 22 is positioned with respect to the first main plate 21, separated by an internal space S2 (see Figure 11).

[0031] The support member 2 has a double-wall structure consisting of a first main plate 21 and a second main plate 22. The support member 2 is a plate-shaped case having an internal space S2. "Outward" refers to the direction in which the two support members 2 are separated from each other. "Inward" refers to the direction in which the two support members 2 are brought closer together.

[0032] As shown in Figure 2, the opposing surface 21a of the first main plate 21 is the surface facing the storage space S1. The opposing surfaces 21a of the two support members 2 face each other. The opposing surfaces 21a are parallel to the YZ plane. As shown in Figure 7, the back surface 21b of the first main plate 21 is the surface opposite to the opposing surface 21a. The back surface 21b faces the internal space S2.

[0033] As shown in Figures 2 and 3, the first main plate 21 has a plurality of engagement holes 23. The engagement holes 23 open to the opposing surface 21a. The engagement holes 23 are formed to penetrate from the opposing surface 21a to the back surface 21b of the first main plate 21 (see Figure 12).

[0034] The engagement holes 23 are, for example, circular in shape when viewed from the thickness direction (width direction X) of the first main plate 21. The shape of the engagement holes 23 is not particularly limited. The shape of the engagement holes 23 may be polygonal (rectangular, etc.), elliptical, etc. Multiple engagement holes 23 form multiple engagement hole groups 24 that are spaced apart in the front-rear direction Y. Multiple engagement hole groups 24 are formed at intervals in the front-rear direction Y.

[0035] The engagement hole group 24 has a plurality of engagement holes 23 formed at different positions in the vertical direction Z. The engagement holes 23 constituting the engagement hole group 24 are arranged at intervals in the vertical direction Z. For example, the engagement holes 23 are formed at equal intervals in the vertical direction Z.

[0036] As shown in Figure 9, the first main plate 21 has a plurality of annular projections 25 formed thereon. The annular projections 25 are formed on the periphery of the engagement holes 23. The annular projections 25 protrude outward from the back surface 21b (towards the second main plate 22) (see Figure 12). The annular projections 25 are, for example, annular or cylindrical in shape with a central axis parallel to the width direction X.

[0037] As shown in Figure 3, the shelf support 7 is detachably attached to the first main plate 21 of the support member 2. As shown in Figures 4 and 5, the shelf support 7 comprises a base plate portion 31, an engaging portion 32, and a shelf board support portion 33. The base plate portion 31 is formed in the shape of a rectangular plate. One main surface of the base plate portion 31 is the first main surface 31a. The main surface opposite the first main surface 31a is the second main surface 31b.

[0038] As shown in Figure 5, the engaging portion 32 is tongue-shaped. The engaging portion 32 has a first portion 32A and a second portion 32B. The first portion 32A protrudes from the second main surface 31b toward the back side (the side from the first main surface 31a toward the second main surface 31b). The second portion 32B protrudes downward from the tip of the first portion 32A.

[0039] The engaging portion 32 can be formed by creating a U-shaped notch in the substrate portion 31 and bending the portion partitioned by this notch toward the back side. The engaging portion 32 is inserted into the engaging hole 23 of the first main plate 21 and engages with the periphery of the engaging hole 23 (see Figure 3). The engaging portion 32 is designed to be able to engage and disengage with respect to the engaging hole 23. The engaging portion 32 selectively engages with the engaging hole 23.

[0040] The shelf support portion 33 is plate-shaped and protrudes from the lower end of the base portion 31 in the forward direction (from the second main surface 31b toward the first main surface 31a). The shelf support portion 33 protrudes, for example, in a direction perpendicular to the first main surface 31a. The shelf support portion 33 is formed in a rectangular plate shape. The shelf support portion 33 can support the end of the shelf 1. The shelf bracket 7 is attached to the two support members 2 and supports both ends of the shelf 1.

[0041] The base plate portion 31, the engaging portion 32, and the shelf support portion 33 are, for example, formed integrally. The base plate portion 31, the engaging portion 32, and the shelf support portion 33 can be formed by bending a single sheet of material.

[0042] As shown in Figure 3, the shelf support 7 can be adjusted in height (position in the vertical Z direction) by selecting the engagement hole 23 into which the engagement portion 32 engages. As shown in Figure 2, the shelf board 1 can be adjusted in height by selecting the height of the shelf support 7 (see Figure 3).

[0043] As shown in Figure 7, the entry restricting member 8 is provided on the back surface 21b of the first main plate 21. The entry restricting member 8 restricts the entry of foreign matter (objects) from the engagement hole 23 into the internal space S2. In other words, the entry restricting member 8 prevents foreign matter from entering the internal space S2 from the engagement hole 23. The entry restricting member 8 is an example of an "entry restricting structure". "Foreign matter" refers to objects different from the components of the item storage fixture 100.

[0044] As shown in Figures 8 to 10, the entry restriction member 8 comprises a restriction plate 41, a mounting plate 42, and one or more connecting parts 43. The restriction plate 41 is, for example, a plate parallel to the YZ plane. The restriction plate 41 is located in the internal space S2. The restriction plate 41 is an example of a "restricting part".

[0045] The restricting plate 41 is, for example, parallel to the back surface 21b. It is desirable that the restricting plate 41 be located away from the back surface 21b. If the restricting plate 41 is located away from the annular projection 25, the engaging portion 32 (see Figure 5) of the shelf support 7 will be able to easily engage with the engaging hole 23 (see Figure 3). It is desirable that the restricting plate 41 be located away from the second main plate 22.

[0046] As shown in Figure 12, the distance L1 between the regulating plate 41 and the opposing surface 21a is preferably 10 mm or less. When the distance L1 is within this range, the effect of restricting foreign matter from entering the internal space S2 through the engagement hole 23 can be enhanced. For example, objects with a length of 10 mm or more will have difficulty entering the internal space S2 through the engagement hole 23.

[0047] As shown in Figure 8, the restricting plate 41 is formed in the shape of a long plate extending in the vertical direction Z. The restricting plate 41 is formed, for example, in a rectangular shape. When viewed from a direction perpendicular to the first main plate 21 (width direction X), the restricting plate 41 overlaps with the plurality of engagement holes 23. The restricting plate 41 is formed so as to cover the engagement holes 23 when viewed from the width direction X.

[0048] The restricting plate 41 is preferably formed to overlap the entire area of ​​the engagement hole 23 when viewed from the width direction X (see Figure 12). In this embodiment, the restricting plate 41 is formed to overlap the entire area of ​​all of the multiple engagement holes 23 that constitute the engagement hole group 24. The restricting plate 41 may be formed to overlap a portion of the engagement hole 23. The restricting plate 41 only needs to be formed to overlap at least a portion of the engagement hole 23.

[0049] The mounting plate 42 has a main portion 44 and two convex portions 45. The mounting plate 42 is superimposed on the back surface 21b of the first main plate 21. The mounting plate 42 is attached to the first main plate 21 by welding, screws, or the like. When viewed from the vertical direction Z, the main portion 44 is positioned in front of (-Y side of) the annular projection 25.

[0050] The convex portion 45 is formed on the portion including the upper end and the portion including the lower end of the main portion 44, respectively. The convex portion 45 protrudes rearward (towards the +Y side) from the rear side edge (+Y side edge) of the main portion 44. The convex portion 45 is rectangular in shape. The convex portion 45 formed on the portion including the upper end of the main portion 44 is located higher than the annular projection 25 formed in the engagement hole 23 at the highest position (upper position). The convex portion 45 formed on the portion including the lower end of the main portion 44 is located lower than the annular projection 25 formed in the engagement hole 23 at the lowest position (lowest position).

[0051] The restricting plate 41 and the mounting plate 42 are connected via connecting portions 43, at least in the portion including the upper end and the portion including the lower end. The connecting portion 43 connects the rear edge (+Y side edge) of the restricting plate 41 and the rear edge (+Y side edge) of the convex portion 45 of the mounting plate 42.

[0052] The restricting plate 41 and the mounting plate 42 extend forward (-Y side) from the connecting portion 43. Since the restricting plate 41 and the mounting plate 42 of the entry restricting member 8 extend to the same side (-Y side), the dimension in the front-rear direction Y can be reduced. The restricting plate and the mounting plate may also extend rearward (+Y side) from the connecting portion.

[0053] [Effects of the article storage fixture according to this embodiment] In the article storage unit 100 according to this embodiment, an entry restriction member 8 (entry restriction structure) is provided, which has a restricting plate 41 that overlaps at least a portion of the engagement hole 23 when viewed from the width direction X. Therefore, the restricting plate 41 can prevent foreign objects from entering the interior of the support member 2 through the engagement hole 23.

[0054] Since the item storage unit 100 has shelves 1, items can be stored on the shelves 1.

[0055] The entry restriction member 8 comprises a mounting plate 42 attached to the first main plate 21 and a connecting portion 43 that connects the restriction plate 41 and the mounting plate 42. Therefore, the restriction plate 41 can be stably installed on the support member 2. Thus, the effect of restricting the entry of foreign objects through the engagement hole 23 can be enhanced.

[0056] Since the entry restriction member 8 has both a restriction plate 41 and a mounting plate 42 extending on the same side (-Y side), the dimension in the front-rear direction Y can be reduced. Therefore, the entry restriction member 8 can be installed even when the internal space S2 of the support member 2 is small.

[0057] The restricting plate 41 extends in the direction of the alignment of the multiple engagement holes 23 and is positioned to overlap the multiple engagement holes 23. Because the restricting plate 41 can restrict the entry of foreign matter into the multiple engagement holes 23, the number of parts can be reduced and the internal structure of the support member 2 can be simplified.

[0058] [Entry restriction member] (First modified example) Figure 13 is a cross-sectional view of an entry restriction member 108, which is a first modified example of entry restriction member 8. Components common to entry restriction member 8 shown in Figure 12 are denoted by the same reference numerals and their explanations are omitted.

[0059] As shown in Figure 13, the entry restriction member 108 (entry restriction structure) comprises a restriction plate 41, a mounting plate 142, and one or more connecting parts 43. The mounting plate 142 is superimposed on the back surface 21b of the first main plate 21. The mounting plate 142 is attached to the first main plate 21 by welding, screwing, or the like. When viewed from the vertical direction Z, the mounting plate 142 is positioned in front of the annular projection 25 (-Y side).

[0060] The restrictor plate 41 and the mounting plate 142 are connected via a connecting portion 43. The connecting portion 43 connects the front edge (-Y side edge) of the restrictor plate 41 and the rear edge (+Y side edge) of the mounting plate 142.

[0061] The restricting plate 41 extends from the connecting portion 43 toward the rear (+Y side). The mounting plate 142 extends from the connecting portion 43 toward the front (-Y side). Because the restricting plate 41 and the mounting plate 142 of the entry restricting member 108 extend toward different sides, the mounting plate 142 can be positioned away from the engagement hole 23 in the front-rear direction Y. Therefore, there are fewer constraints on the shape and size of the mounting plate 142. Consequently, the restricting plate 41 can be stably installed on the support member 2. Thus, the effect of restricting the entry of foreign objects from the engagement hole 23 can be enhanced. Note that the entry restricting member may also have the restricting plate extending toward the front (-Y side) from the connecting portion and the mounting plate extending toward the rear (+Y side) from the connecting portion.

[0062] [Entry restriction member] (Second modified example) Figure 14 is a cross-sectional view of an entry restriction member 208, which is a second modified example of the entry restriction member 8. Components common to both the entry restriction member 8 and the entry restriction member 8 shown in Figure 12 are denoted by the same reference numerals and their explanations are omitted.

[0063] As shown in Figure 14, the entry restriction member 208 (entry restriction structure) comprises a restriction plate 41, first and second mounting plates 242A, 242B, and first and second connecting parts 243A, 243B.

[0064] The first mounting plate 242A is positioned in front of the annular projection 25 (-Y side) when viewed from the vertical direction Z. The second mounting plate 242B is positioned behind the annular projection 25 (+Y side) when viewed from the vertical direction Z. The first and second mounting plates 242A and 242B are superimposed on the back surface 21b of the first main plate 21. The first and second mounting plates 242A and 242B are attached to the first main plate 21 by welding, screws, or the like.

[0065] The first connecting portion 243A connects the front edge (-Y side edge) (one side edge) of the regulating plate 41 to the rear edge (+Y side edge) of the first mounting plate 242A. The front edge of the regulating plate 41 is connected to the first mounting plate 242A via the first connecting portion 243A.

[0066] The second connecting portion 243B connects the rear edge (+Y side edge) (the other side edge) of the regulating plate 41 to the front edge (-Y side edge) of the second mounting plate 242B. The rear edge of the regulating plate 41 is connected to the second mounting plate 242B via the second connecting portion 243B.

[0067] The entry restriction member 208 is configured such that the restriction plate 41 is connected to the first and second mounting plates 242A and 242B at its front and rear edges, respectively, allowing the restriction plate 41 to be stably installed on the support member 2. This enhances the effect of restricting the entry of foreign objects through the engagement hole 23.

[0068] [Entry restriction member] (Third modified example) Figure 15 is a cross-sectional view of an entry restriction member 308, which is a third modified example of the entry restriction member 8. Common components with other examples of entry restriction members are denoted by the same reference numerals and their descriptions are omitted.

[0069] As shown in Figure 15, the entry restriction member 308 (entry restriction structure) comprises a restriction plate 341 (restriction part) and a mounting cylinder part 342. The mounting cylinder part 342 protrudes from one side of the restriction plate 341. The inner diameter of the mounting cylinder part 342 is approximately the same as, or slightly larger than, the outer diameter of the annular projection part 25. The mounting cylinder part 342 is fitted onto the annular projection part 25 and is locked to the outer circumferential surface of the annular projection part 25 by friction.

[0070] Since the entry restricting member 308 can block the engagement hole 23, it can enhance the effect of restricting the entry of foreign matter from the engagement hole 23.

[0071] [Entry restriction member] (4th modified example) Figure 16 is a cross-sectional view of an entry restriction member 408, which is a fourth modified example of the entry restriction member 8. Common components with other examples of entry restriction members are denoted by the same reference numerals and their descriptions are omitted.

[0072] As shown in Figure 16, the entry restriction member 408 (entry restriction structure) has the same configuration as the entry restriction member 208 (see Figure 14). The first and second mounting plates 242A and 242B are attached to the back surface 22b of the second main plate 22 by welding, screwing, etc. The back surface 22b is the surface opposite to the outer surface 22a of the second main plate 22. The back surface 22b faces the back surface 21b of the first main plate 21.

[0073] Since the entry restriction member 408 is attached to the second main plate 22, it is easy to secure space on the back surface 21b of the first main plate 21 for installing other components. Therefore, the degree of design freedom for the first main plate 21 can be increased.

[0074] [Entry control structure] Figure 17 is a cross-sectional view of another example of an access control structure. Components previously described are denoted by the same reference numerals and their explanations are omitted.

[0075] As shown in Figure 17, the entry restriction structure 508 is a restricting projection 540 formed integrally with the second main plate 22. The restricting projection 540 protrudes from the back surface 22b of the second main plate 22 toward the first main plate 21.

[0076] The restricting projection 540 has a restricting plate 541 and a side plate 542. The restricting plate 541 is positioned in the internal space S2 and overlaps at least a portion of the engagement hole 23 when viewed from the width direction X. The restricting plate 541 is an example of a “restricting portion”. The side plate 542 extends outward from, for example, the front and rear side edges of the restricting plate 541. The restricting projection 540 can be formed by press-forming a portion of the second main plate 22.

[0077] Since the entry restriction structure 508 is formed integrally with the second main plate 22, the internal structure of the support member 2 can be simplified. Therefore, it is easier to secure space in the internal space S2. Thus, the degree of design freedom for the support member 2 can be increased.

[0078] Furthermore, it is possible to replace the components in the above embodiments with well-known components as appropriate, without departing from the spirit of the present invention. The above embodiments and modifications may be combined or substituted as appropriate. In furniture, the number of shelves is not particularly limited. There should be at least one shelf. In other words, the number of shelves can be one or multiple (any number of two or more). As shown in Figures 2 and 3, the multiple engagement holes 23 constituting the engagement hole group 24 are formed in the vertical direction Z. However, the direction in which the multiple engagement holes constituting the engagement hole group are arranged is not limited to the vertical direction Z, but may be in a direction inclined with respect to the vertical direction. The direction in which the engagement holes are arranged may also be in the front-to-back direction. [Explanation of Symbols]
