Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the configuration disclosed in Patent Document 1, it is necessary to form the ends of the shelf board in an arc shape corresponding to the outer surface of the columns, which has problems such as being difficult to manufacture and time-consuming.

[0006] Therefore, the present invention has been made in view of the above circumstances, and provides a bracket, a shelf board structure, and a shelf board device that can be easily manufactured and can connect the shelf board and the columns.

Means for Solving the Problems

[0007] In order to achieve the above object, the present invention employs the following means. In other words, the bracket according to the present invention is a bracket that connects a support column extending in the vertical direction and having an arc portion formed in an arc shape when viewed from above and below, and a shelf board supported by the support column, comprising a shelf board connecting portion connected to the shelf board, and a support column connecting portion extending in the vertical direction from the shelf board connecting portion and connected to the support column, wherein the support column connecting portion is formed in a flat plate shape and has a pair of connecting plate portions whose plate surfaces intersect in a direction, and the arc portion of the support column is connected to the plate surfaces of the pair of connecting plate portions.

[0008] In this type of bracket, the connecting plate portion of the bracket that connects to the support column is flat, so it does not need to be manufactured in an arc shape to match the shape of the arc portion of the support column, making it easy to manufacture. Furthermore, although the support columns are arc-shaped, they are fixed to the surfaces of a pair of connecting plates that face in directions where their respective plate surfaces intersect. This allows for positioning at the plate surface, suppresses misalignment of the support columns, and enables connection between the shelf board and the support columns via brackets.

[0009] Furthermore, in the shelf structure according to the present invention, the pair of connecting plate portions may be connected.

[0010] In this shelf structure, the pair of connecting plates are connected, which increases the rigidity of the support column connection.

[0011] Furthermore, in the shelf device according to the present invention, the shelf connection portion may have an insertion portion through which the support column is inserted in the vertical direction.

[0012] In this type of shelf device, the shelf connection section has an insertion section through which the support column is inserted vertically, making it easy to position the support column relative to the shelf connection section.

[0013] Furthermore, the shelf board device according to the present invention comprises a bracket as described in any one of the above, and a shelf board connected to the shelf board connection portion of the bracket.

[0014] In this type of shelf device, the connecting plate portion of the bracket that connects to the support column is flat, so it does not need to be manufactured in an arc shape to match the shape of the arc portion of the support column, making it easy to manufacture. Furthermore, although the support columns are arc-shaped, they are fixed to the surfaces of a pair of connecting plates that face in directions where their respective plate surfaces intersect. This allows for positioning at the plate surface, suppresses misalignment of the support columns, and enables connection between the shelf board and the support columns via brackets.

[0015] Furthermore, in the shelf device according to the present invention, the shelf has a pair of shelf-side fixing portions that gradually inclinate to one side in the vertical direction as they extend toward both sides in a first direction intersecting the vertical direction, the shelf connection portion has a pair of bracket-side fixing portions that gradually inclinate to one side in the vertical direction as they extend toward both sides in the first direction, and the pair of bracket-side fixing portions may be fixed to the pair of shelf-side fixing portions by fastening members.

[0016] In this shelf device configuration, a pair of bracket-side fixing parts, which gradually incline to one side in the vertical direction as they extend toward both sides in the first direction, are fixed by fastening members to the pair of shelf-side fixing parts, which gradually incline to one side in the vertical direction as they extend toward both sides in the first direction. Therefore, rotation of the bracket with the vertical direction as the axial direction can be suppressed.

[0017] Furthermore, in the shelf device according to the present invention, a recess that is recessed upward is formed on the lower surface of the shelf, The support column connecting portion of the bracket may extend upward from the shelf board connecting portion and be positioned in the recess.

[0018] In this configured shelf device, the bracket's column connection portion is positioned in an upwardly recessed recess formed on the underside of the shelf. Therefore, the column connection portion is not conspicuous when viewed from the side, resulting in a good appearance.

[0019] In addition, in the shelf board device according to the present invention, it includes the bracket according to any one of the above, a shelf board connected to the shelf board connection portion of the bracket, and a support column that supports the shelf board and has an arc portion at least partially formed in an arc shape and extends in the vertical direction.

[0020] In the shelf board device configured as described above, since the connection plate portion of the bracket connected to the support column is flat, there is no need to manufacture it in an arc shape according to the shape of the arc portion of the support column, and it can be easily manufactured. Also, although the support column is arc-shaped, since it is fixed to the plate surfaces of a pair of connection plate portions facing in the direction where the plate surfaces of each other intersect, it is positioned by the plate surface and the displacement of the support column is suppressed, and the shelf board and the support column can be connected via the bracket.

Effect of the Invention

[0021] According to the bracket, shelf board structure, and shelf board device of the present invention, it can be easily manufactured and the shelf board and the support column can be connected.

Mode for Carrying Out the Invention

[0023] (First Embodiment) Next, a first embodiment of the present invention will be described with reference to the drawings. In the embodiments described below, corresponding components may be denoted by the same reference numerals and their descriptions may be omitted. In the following description, expressions indicating relative or absolute arrangements such as "parallel," "orthogonal," "center," and "coaxial" will not only strictly represent such arrangements, but will also represent states in which the surfaces are relatively displaced by an angle or distance that allows for tolerances or the same function to be obtained. Furthermore, in this embodiment, "facing each other" is not limited to cases where the orthogonal directions (normal directions) of the two surfaces coincide with each other, but also includes cases where the orthogonal directions intersect.

[0024] <Shelf board device> Figure 1 is a perspective view of a shelf device according to one embodiment of the present invention. The shelf device 100 shown in Figure 1 is installed on the floor in various facilities (such as offices and public facilities). The shelf device 100 comprises multiple shelf structures 1, multiple support columns 3, and multiple leg members 4.

[0025] In the following explanation, the direction in which the user approaches the shelf device 100 may be referred to as the front-to-back direction Df, the horizontal direction perpendicular to the front-to-back direction Df may be referred to as the width direction Dw, and the direction perpendicular to both the front-to-back direction Df and the width direction Dw may be referred to as the up-and-down direction Dv. Furthermore, in the front-to-back direction Df and the width direction Dw, the direction toward the center of the shelf device 100 may be referred to as the "inside," and the direction toward the opposite side (end side) may be referred to as the "outside."

[0026] <Shelf structure> Figure 2 is an exploded perspective view of a part of the shelf device 100. As shown in Figure 2, the shelf structure 1 comprises a shelf board 10 and a plurality of brackets 20. In this embodiment, two brackets 20 are provided on each shelf board 10, spaced apart in the width direction Dw. The brackets 20 are components for connecting the shelf board 10 and the support column 3, and are positioned where the support column 3 penetrates the shelf board 10. Multiple shelf structures 1 are provided with spacing in the vertical direction. In this embodiment, three shelf structures 1 are provided with spacing in the vertical direction. The number of brackets 20 and the number of shelf structures 1 can be set as appropriate.

[0027] <Shelf board> As shown in Figure 1, the shelf board 10 is formed in a substantially flat shape. The surface of the shelf board 10 faces the vertical direction Dv. When viewed from the vertical direction Dv (plan view), the shelf board 10 is substantially rectangular. The longer side of the substantially rectangular shelf board 10 faces the width direction Dw. The shorter side of the shelf board 10 faces the front-to-back direction Df. Note that the shape of the shelf board 10 as viewed from the vertical direction Dv can be set as appropriate. The longer side of the substantially rectangular shelf board 10 may face the front-to-back direction Df, and the shorter side may face the width direction Dw.

[0028] In this embodiment, three shelves 10 are arranged with a gap between them in the vertical direction. They may be labeled 10A, 10B, and 10C from top to bottom.

[0029] Figure 3 is a perspective view of the shelf. As shown in Figure 3, the shelf board 10 is constructed by assembling two lower members 12 (front and rear) to the underside of an upper member 11, and assembling end members 13 to both ends in the width direction Dw. The upper member 11, lower members 12, and end members 13 are each formed by bending a sheet of metal. The shelf board 10 may be constructed by bending a single sheet of metal, or by assembling two or more arbitrary sheets of metal. Furthermore, the shelf board 10 may be made of a solid material.

[0030] Figure 4 is a cross-sectional view of the shelf board. As shown in Figures 3 and 4, the shelf board 10 has a shelf board upper surface 17, a shelf board end surface 18, and a shelf board lower surface 19.

[0031] The top surface 17 of the shelf faces upward, allowing items to be placed on it. The top surface 17 of the shelf has an upper plate portion 111.

[0032] As shown in Figure 4, the upper plate portion 111 is formed in a plate shape. The surface of the upper plate portion 111 is oriented in the vertical direction Dv. The upper plate portion 111 is rectangular in plan view (see Figure 1). The upper surface 111u of the upper plate portion 111 is a flat surface on which items can be placed.

[0033] The shelf end face 18 is located at the end face Df in the front-rear direction of the shelf 10. The shelf top surface 17 has an end plate portion 112.

[0034] The end plate portion 112 extends downward from both ends of the upper plate portion 111 in the front-to-back direction Df. The end plate portion 112 is formed in a plate shape. The plate surface of the end plate portion 112 faces the front-to-back direction Df.

[0035] The underside 19 of the shelf board faces downward. The underside 19 of the shelf board has a lower plate portion 113, an outer inclined plate portion 114, an inner inclined plate portion (shelf board side fixing portion) 115, upper and lower plate portions 116, and a back plate portion 117.

[0036] The lower plate portion 113 extends inward in the front-to-back direction Df from the lower end of the end plate portion 112. The lower plate portion 113 is formed in a plate shape. The surface of the lower plate portion 113 is arranged along a horizontal plane. At both ends of the shelf board 10 in the front-to-back direction Df, a thin-walled portion 15 is formed by the upper plate portion 111 and the lower plate portion 113.

[0037] The outer inclined plate portion 114 extends inward from the inner end of the lower plate portion 113 in the front-rear direction Df. The outer inclined plate portion 114 is positioned adjacent to the inner side of the lower plate portion 113 in the front-rear direction Df. The outer inclined plate portion 114 is positioned closer to the end 10a of the shelf board 10 in the front-rear direction Df than the inner inclined plate portion 115. The outer inclined plate portion 114 is inclined with respect to the horizontal plane so that it gradually slopes downward as it approaches the inner side of the front-rear direction Df. The outer inclined plate portion 114 is formed in a plate shape. The plate surface of the outer inclined plate portion 114 faces in directions that intersect the vertical direction Dv and the front-rear direction Df. The length of the outer inclined plate portion 114 in the front-rear direction Df is length L1. The inclination angle of the outer inclined plate portion 114 with respect to the horizontal plane is angle θ1. The outer inclined plate portion 114 is formed in pairs spaced apart on both sides of the front-rear direction (first direction) Df. Furthermore, the outer inclined plate portion 114 is formed with a greater inclination than the chamfer generally formed on the end face of a shelf board.

[0038] The inner inclined plate portion 115 extends inward from the inner end of the outer inclined plate portion 114 in the front-rear direction Df. The inner inclined plate portion 115 is adjacent to the inner side of the outer inclined plate portion 114 in the front-rear direction Df and is positioned closer to the center of the front-rear direction Df. The inner inclined plate portion 115 is inclined with respect to the horizontal plane so as it moves inward in the front-rear direction Df. The inner inclined plate portion 115 is formed in a plate shape. The plate surface of the inner inclined plate portion 115 faces in directions that intersect the vertical direction Dv and the front-rear direction Df. The length of the inner inclined plate portion 115 in the front-rear direction Df is length L2. The inclination angle of the inner inclined plate portion 115 with respect to the horizontal plane is angle θ2. The inner inclined plate portion 115 is formed in pairs, spaced apart on both sides of the front-rear direction (first direction) Df.

[0039] On the shelf board 10, the center side of the front-to-back direction Df is formed by the upper plate portion 111, the outer inclined plate portion 114, and the inner inclined plate portion 115, creating a thick, substantial section 16.

[0040] The length L1 of the outer inclined plate portion 114 is longer than the length L2 of the inner inclined plate portion 115. The angle θ1 of the outer inclined plate portion 114 is smaller than the angle θ2 of the inner inclined plate portion 115.

[0041] The upper and lower plate portions 116 extend upward from the inner end of the inner inclined plate portion 115 in the front-rear direction Df. The upper and lower plate portions 116 are formed in a plate shape. The plate surface of the upper and lower plate portions 116 faces the front-rear direction Df.

[0042] As shown in Figure 3, the back plate portion 117 extends inward in the front-to-back direction Df from the upper end of the upper and lower plate portions 116. The back plate portion 117 is positioned along the lower surface of the upper plate portion 111. The back plate portion 117 is formed in a plate shape. The plate surface of the back plate portion 117 faces in the up-to-down direction Dv. The back plate portion 117 is joined to the lower surface of the upper plate portion 111.

[0043] As shown in Figure 4, a first recess C1 that is recessed upward is formed on the lower surface 19 of the shelf board by the 115 on both sides Df in the front-rear direction and the upper and lower plate portions 116 on both sides Df in the front-rear direction. Furthermore, on the inner side of the first recess C1 in the front-rear direction, a second recess (recess) C2 that is recessed upward is formed on the lower side of the shelf board 10 by the upper and lower plate portions 116 on both sides Df in the front-rear direction. The second recess C2 is a part of the first recess C1.

[0044] As shown in Figure 1, shelves 10B and 10C have support holes 111s formed in the upper plate portion 111 through which the support columns 3, described later, pass. The support holes 111s are formed in two locations spaced apart in the width direction Dw. Shelf 10A does not have support holes 111s.

[0045] <bracket> As shown in Figure 2, the bracket 20 has a shelf board connection part 21 and a support column connection part 22. The shelf board connection part 21 and the support column connection part 22 are each formed by bending a plate material. The shelf board connection part 21 and the support column connection part 22 are joined together.

[0046] The shelf board connection part 21 is connected to the shelf board 10. The shelf board connection part 21 comprises a support plate part 211 and an inclined plate part (bracket side fixing part) 212.

[0047] The support plate portion 211 is formed in a plate shape. The surface of the support plate portion 211 is oriented in the vertical direction Dv. The support plate portion 211 is roughly rectangular when viewed from the vertical direction Dv. A notch 213 is formed at the inner end 211a of the support plate portion 211 in the width direction Dw, extending outward in the width direction Dw.

[0048] Figure 5 is a cross-sectional view of the shelf device 100 along the horizontal plane. The support plate portion 211 has an insertion portion 214 that penetrates in the vertical direction Dv. As shown in Figure 5, the insertion portion 214 is located on the outer end 211b side in the width direction Dw, rather than the center in the width direction Dw of the support plate portion 211. The support column 3 is inserted through the insertion portion 214.

[0049] As shown in Figure 2, the inclined plate portions 212 are provided at both ends of the support plate portion 211 in the front-rear direction. The inclined plate portions 212 are inclined so as they move outward in the front-rear direction Df, they gradually move downward (to one side in the up-down direction). The pair of inclined plate portions 212 are spaced apart in the front-rear direction Df.

[0050] The inclined plate portion 212 has screw holes 212a that penetrate in the thickness direction of the plate. Two screw holes 212a are formed, spaced apart in the width direction Dw. The number of screw holes 212a can be set as appropriate.

[0051] Figure 6 is a cross-sectional view of the shelf device 100 along the vertical plane. As shown in Figure 6, the inclined plate portion 212 is positioned along the underside of the inner inclined plate portion 115 of the shelf board 10. A screw (fastening member) 212b is inserted through the screw hole 212a and screwed into the screw hole 115a formed in the inner inclined plate portion 115 of the shelf board 10. In this way, the bracket 20 is fixed to the shelf board 10.

[0052] As shown in Figure 2, the column connecting portion 22 extends upward from the support plate portion 211. The column connecting portion 22 has a pair of connecting plate portions 221.

[0053] The connecting plate portion 221 is formed in a flat plate shape. The plate surface of the connecting plate portion 221 is arranged along the vertical direction Dv. As shown in Figure 5, the pair of connecting plate portions 221 are arranged so that their plate surfaces intersect in the direction of each other. The ends of the pair of connecting plate portions 221 are connected perpendicularly at approximately a right angle. The pair of connecting plate portions 221 are formed by bending a single plate material. Screw holes 221a are formed in the connecting plate portion 221, penetrating in the thickness direction.

[0054] <Strut> The support columns 3 extend in the vertical direction Dv. Two support columns 3 are installed spaced apart in the width direction Dw. The support columns 3 are formed in a cylindrical shape. The outer circumference of each support column 3 has an arc-shaped section 31 that is formed in an arc shape when viewed from the vertical direction Dv. The number of support columns 3 can be set as appropriate.

[0055] The inner edge shape of the insertion portion 214 formed on the bracket 20 is approximately the same as or slightly larger than the arc portion 31. The support column 3 is inserted through the insertion portion 214.

[0056] The arc portion 31 of the support column 3 abuts against the inner surface (plate surface) 221c of the pair of connecting plate portions 221 of the bracket 20. A screw hole 221a is formed in the connecting plate portion 221 at the location where the arc portion 31 of the support column 3 abuts.

[0057] The screw 221b is inserted through the screw hole 221a of the connecting plate portion 221 of the bracket 20 and screwed into the screw hole 31a formed in the support column 3. The arc portion 31 of the support column 3 is connected to the inner surface 221c of the connecting plate portion 221. In this way, the support column 3 is connected to the bracket 20. The support column 3 supports the shelf board 10 via the bracket 20. Alternatively, a bolt and nut may be used instead of the screw 221b.

[0058] As shown in Figure 6, the pair of connecting plate portions 221 of the bracket 20 are positioned in the second recess C2 of the shelf board 10.

[0059] <Legs> As shown in Figure 1, the leg members 4 are provided at the bottom of the shelf board 10C and are installed on the floor surface. A height-adjustable adjuster (not shown) may be provided at the bottom of the leg members 4. The leg members 4 are provided at four locations near the four corners of the shelf board 10C, but the number of leg members 4 can be set as appropriate.

[0060] As shown in Figure 6, the support column 3 has a wiring hole 33 that penetrates radially. Wiring (not shown) inserted into the support column 3 is taken out from the wiring hole 33 and placed in the width direction Dw within the second recess C2 through the notch 213 of the bracket 20. The lower side of the second recess C2 can be covered with a wiring cover (not shown).

[0061] When assembling the shelf unit 100, install the support column 3 and pass it through the insertion portion 214 of the bracket 20. At the designated position, connect the support column 3 and the bracket 20 with screws 221b. For shelves 10B and 10C, pass the support column through the support hole 111s. Connect the shelf 10 and the bracket 20 with screws 221b.

[0062] In the shelf device 100 configured in this way, the connecting plate portion 221 of the bracket 20 connected to the support column 3 is flat, so it does not need to be manufactured in an arc shape to match the shape of the arc portion 31 of the support column 3, and can be manufactured easily.

[0063] Furthermore, although the support column 3 is arc-shaped, it is fixed to the inner surface 221c of a pair of connecting plate portions 221 whose respective plate surfaces intersect. This allows the support column 3 to be positioned on the inner surface 221c, suppressing any misalignment of the support column 3, and enabling the shelf board 10 and the support column 3 to be connected via the bracket 20.

[0064] Furthermore, since the pair of connecting plate sections 221 are connected, the rigidity of the support column connecting section 22 can be increased.

[0065] Furthermore, since the support plate portion 211 has an insertion portion 214 through which the support column 3 is inserted vertically, it is easy to position the support column 3 relative to the support plate portion 211.

[0066] Furthermore, a pair of inclined plate portions 212 that gradually slope downward as they move outward in the front-rear direction Df of the bracket 20 are fixed by screws 212b to a pair of inner inclined plate portions 115 that gradually slope downward as they move outward in the front-rear direction Df of the shelf board 10. Thus, rotation of the bracket 20 with the vertical direction Dv as the axial direction can be suppressed.

[0067] Furthermore, the pair of connecting plate portions 221 of the bracket 20 are positioned in the upwardly recessed second recess C2 formed on the lower surface of the shelf board 10. Therefore, when viewed from the front-to-back direction Df, the pair of connecting plate portions 221 are hidden by the thickened portion 16 and are not conspicuous, resulting in a good appearance.

[0068] (Second embodiment) Next, a shelf board device according to the second embodiment of the present invention will be described mainly with reference to Figure 7. In the embodiments described below, components corresponding to the embodiments shown above may be denoted by the same reference numerals and their descriptions may be omitted. Figure 7 is a cross-sectional view along the horizontal plane of the shelf device according to the second embodiment of the present invention. As shown in Figure 7, in the shelf device 100A according to this embodiment, the insertion portion 215 formed in the bracket 20A is notched so as to be recessed inward in the width direction Dw from the end portion 211b of the support plate portion 211.

[0069] The support column 3A has an elongated shape in the width direction Dw when viewed from the vertical direction Dv. On both sides of the width direction Dw, the support column 3A has arc-shaped portions 32 that bulge outward when viewed from the vertical direction Dv.

[0070] Of the pair of arc portions 32, the arc portion 32A, which is located on the inside in the width direction Dw, is in contact with the inner surface 221c of the connecting plate portion 221. The inner edge portion 215a on the inside in the width direction Dw of the insertion portion 215 has a shape corresponding to the arc portion 32A.

[0071] In the shelf device 100A configured in this way, the connecting plate portion 221 of the bracket 20A connected to the support column 3A is flat, so it does not need to be manufactured in an arc shape to match the shape of the arc portion 32 of the support column 3A, and can be manufactured easily.

[0072] Furthermore, although the support column 3A is arc-shaped, it is fixed to the inner surface 221c of a pair of connecting plate portions 221 whose respective plate surfaces intersect. This allows the support column 3A to be positioned on the inner surface 221c, suppressing any misalignment of the support column 3A, and enabling the shelf board 10 and the support column 3A to be connected via the bracket 20A.

[0073] The insertion portion 215 formed in the support plate portion 211 of the bracket 20A is a notch that is recessed from the end portion 211b. Therefore, when inserting the support column 3A into the insertion portion 215, the support column 3A can be moved inward in the width direction Dw from the end portion 211b side and positioned accordingly, resulting in good assembly of the shelf board device 100.

[0074] (Other variations) While preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments. Additions, omissions, substitutions, and other modifications are possible without departing from the spirit of the present invention. The present invention is not limited by the above description, but only by the appended claims.

[0075] In the embodiment described above, the pair of connecting plate portions 221 are connected, but this is not limited to that. The pair of connecting plate portions may be arranged spaced apart from each other without being connected.

[0076] Furthermore, in the embodiment described above, the pair of connecting plate portions 221 are approximately perpendicular to each other, but are not limited to this. The angle formed by the pair of connecting plate portions 221 when they are connected, and the angle formed by the extensions of the pair of connecting plate portions 221 when they are not connected, can be set as appropriate. In either case, it is sufficient that the arc portion of the support column is connected to the inner surface of the angle that is less angular among the angles formed by the pair of connecting plate portions or extensions.

[0077] Furthermore, in the embodiment described above, at least a portion of the inner edge of the insertion portion 215 formed in the support plate portion 211 of the bracket 20A has a shape corresponding to the arc portion 32A of the support column 3A, but this is not limited to this. At least a portion of the insertion portion 215 does not have to have a shape corresponding to the arc portion 32A.

[0078] Furthermore, in the embodiment described above, the connecting plate portion 221 of the bracket 20 and the support column 3 are connected by a screw 221b, but this is not the only option. The support column connecting portion and the support column may be connected by clamping them together with a clip or the like. Alternatively, a locking portion formed on either the support column connecting portion or the support column may be locked into a locking portion formed on the other of the support column connecting portion and the support column. The configuration for connecting the support column connecting portion and the support column can be set as appropriate.
