Next, the other support part is magnetically attached to the wall so that the other support part can be attached to the placed shelf. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2019-146781 DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0004] The wall furniture described above has a pair of separate rectangular support parts for each set, so the work of magnetically attaching the support parts to the wall surface must be done at least twice, which is time-consuming to install. When disassembling, the procedure is reversed, which is also time-consuming. Furthermore, at least two rectangular support sections are required for one set of wall furniture, which is disadvantageous in terms of the number of parts.

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0014] [First embodiment] Fig. 1 is an external perspective view of the assembly rack 10 of the first embodiment, and Fig. 2 is an exploded perspective view of the assembly rack 10 of the first embodiment. Fig. 3 is a plan sectional view of the assembly rack 10 of the first embodiment, where (a) shows a sectional view taken along line AA in Fig. 1, and (b) shows the state when the fixed plate 1 is peeled off. In these figures, including some of the figures described below, the three axes of the Cartesian coordinate system are XYZ, and the magnetic wall surface W is perpendicular to the XY plane and parallel to the ZX plane. The scale of each figure is not necessarily accurate, and some elements are drawn simply to make the present invention easier to understand. The same reference numerals are used for the left-hand and right-hand components that are the same or similar.

[0015] As shown in Figures 1 to 3, the knockdown rack 10 comprises a fixed plate 1, brackets 3, and shelves 4, and is detachably attached to a magnetic wall surface W by a magnetic sheet 21 provided on the fixed plate 1. The fixed plate 1, brackets 3, and shelves 4 can be separated without tools such as a screwdriver. Furthermore, no tools are required for assembly.

[0016] Next, each of the components of the assembly rack 10 will be described in detail. Fig. 4 is a perspective view of the fixed plate 1, where (a) shows the front side and (b) shows the back side. Fig. 5 is a two-sided view of the magnetic sheet 21, where (a) shows a front view and (b) shows a side view. Fig. 6 is a perspective view of the bracket 3, where (a) shows the bracket 3 for the left side and (b) shows the bracket 3 for the right side. Fig. 7 is a perspective view of the shelf board 4, where (a) shows the front side and (b) shows the back side.

[0017] As shown in FIG. 4, the fixed plate 1 includes a substrate 11 and a magnet sheet 21. The substrate 11 is made of a rectangular thin metal plate having a thickness of about 0.1 mm to 2 mm, and has a pair of left and right ribs 12 formed on both sides in the width direction X. Each rib 12 is elongated and extends continuously in the up-down direction Z while protruding from the substrate surface by a predetermined height. More specifically, as shown in Fig. 3, the substrate 11 has two opposing side walls 121 and a top plate 122 connecting the two side walls 121 at their tops, and has a U-shape in plan view, forming an internal space S1.

[0018] Furthermore, the top plate 122 of the rib 12 is provided with a plurality of long through holes 13 drilled at equal intervals L1 along the up-down direction Z of the rib 12. In other words, these holes have their axes perpendicular to the magnetic surface of the magnetic sheet 21. The long through holes 13 are sized so that the hooks 32 (see FIG. 6) of the bracket 3 can be inserted and dropped into them to engage with them. The internal space S1 is large enough to accommodate the hook 32 inserted into the through hole 13 in the rib 12. Such a substrate 11 is produced, for example, by bending both the left and right sides of a single rectangular thin metal plate to form ribs 12, and then drilling a plurality of long through holes 13 in the top plate 122 of the rib 12. Alternatively, the order may be reversed, i.e., drilling the long through holes 13 first, and then performing the bending process.

[0019] A magnet sheet 21 is fixed to the surface of the substrate 11 on the non-protruding side of the ribs 12 by an adhesive.

[0020] The magnet sheet 21 is a flexible sheet-like magnet with an area slightly smaller than that of the substrate 11 and a thickness of 0.2 mm to 5 mm, and is a double-sided multi-pole magnetized type as shown in Fig. 5. That is, on each of the front and back surfaces, magnetic poles 22, 23 (N pole and S pole) of a constant width and different polarities are formed alternately in stripes at equal intervals, forming magnetized lines 24X at a constant pitch.

[0021] Such a magnet sheet 21 is produced by forming a mixture of fine powder of a hard magnetic material and a small amount of organic polymer elastomer as a binder into a sheet by a molding method such as rolling or extrusion, and magnetizing the surface. In order to obtain sufficient magnetic attraction, it is preferable to use an anisotropic hard magnetic material. The magnet sheet 21 is fixed to the substrate 11. If the substrate 11 has the properties of a soft magnetic material, a yoke effect is generated, and a larger magnetic flux density is generated on the magnetic surface of the magnet sheet 21 than when the magnet sheet 21 is alone, resulting in a larger magnetic force. The thin metal plate having soft magnetic properties can be made of steel, ferritic stainless steel, etc. It is also possible to use a synthetic resin such as plastic instead of metal.

[0022] The thickness of the magnetic sheet 21 and the substrate 11 is set within the above range for the following reason. That is, it is to ensure that the fixed plate 1, i.e., the combination of the substrate 11 and the magnetic sheet 21, has suitable flexibility and magnetic adhesion to the magnetic wall surface W. More specifically, if the thickness of the magnetic sheet 21 exceeds 5 mm, it becomes difficult to ensure flexibility, and if it is less than 0.2 mm, sufficient magnetic adhesion cannot be expected. Furthermore, if the thickness of the substrate 11 exceeds 2 mm, it becomes difficult to ensure flexibility and the weight increases unnecessarily, and if it is less than 0.1 mm, a sufficient yoke effect cannot be expected.

[0023] As shown in Figure 6, the bracket 3 has a shape comprising a trapezoidal frame 31, two hooks 32 spaced apart by an interval L1 on the lower bottom 311 of the frame 31 along its base, and a rectangular base 33 having a surface perpendicular to the frame surface and having through holes 34 at two locations, front and rear, along the longitudinal direction. Here, the distance L1 between the two hooks 32 is set to the distance L1 between the adjacent long through holes 13 in the rib 12 (see FIG. 4(a)).

[0024] Such a shaped body can be manufactured, for example, through a process of cutting hooks 32 at two locations on the lower base of a trapezoidal metal plate, a process of bending the portion that will become the base 33, and a process of drilling through holes 34 at two locations on the front and back of the base 33. Note that the bracket 3 is available in left and right versions, as shown in Figures 6(a) and 6(b), and each version has a mirror image (symmetrical) shape.

[0025] As shown in Fig. 7, the shelf board 4 is made of a rectangular board with a front side surface 41 serving as a support surface. It is made of wood, synthetic resin, or metal. Furthermore, protrusions 44 are provided near the four corners of the back side surface 42 of the shelf board 4. The protrusions 44 are provided at positions corresponding to the through holes 34 of the base 33 of the bracket 3, and are of a shape and size that fits into the through holes 34. The bracket 3 and the shelf board 4 can also be joined together to form an integrated structure (for example, see Fig. 13(b) described later).

[0026] The prerequisite for the knockdown rack 10 having the above-mentioned components is that it is attached by magnetic attraction to a magnetic wall W. For the magnetic wall W, a wall material is used in which wallpaper is attached to one side of a thin foil or sheet steel having a thickness of about 0.1 mm to 1 mm.

[0027] Next, the procedure for assembling the assembly rack 10 will be described. FIG. 8 is a perspective view showing the assembly procedure of the assembly rack 10. As shown in FIG.

[0028] First, as shown in FIG. 8(a), the fixed plate 1 is attached to the magnetic wall surface W. When attaching, the left and right ends of the fixed plate 1 are held with the left and right hands, respectively, and the magnetic surface of the magnetic sheet 21 is placed facing the magnetic wall surface W, and the magnetic sheet 21 is placed against the magnetic wall surface W to be magnetically attached with the upper edge of the substrate 11 held horizontally. In order to obtain an accurate horizontal state, a bubble-type level may be used. In this case, the work is made easier if the base of the bubble tube is placed, for example, on the top of the rib 12. If the magnetic attachment is made out of horizontality, the fixed plate 1 is removed once, the angle is readjusted, and the plate is reattached. Here, the substrate 11 and the magnetic sheet 21 have flexibility in the combined state. Therefore, when removing the fixed plate 1, a part of it can be bent and peeled off as shown in FIG. 3(b).

[0029] Next, the hooks 32, 32 of the left and right brackets 3, 3 are inserted and dropped into the long through holes 13, 13 at the same height in the left and right ribs 12, 12, respectively, and are engaged as shown in FIG. 8(b).

[0030] Next, the shelf board 4 is attached. When installing, the left and right sides of the shelf board 4 are held in the left and right hands, respectively, with the front side 41 facing upward, and the shelf board 4 is placed horizontally between the bases 33, 33 of the left and right brackets 3, 3, as shown in Figure 8(c). At this time, the protrusions 44 on the back side 42 of the shelf board 4 are fitted into the through holes 34 of the bases 33, 33 of the brackets 3, 3. This restrains the shelf board 4 on the bases 33, 33. In other words, the shelf board 4 is prevented from shifting out of position on the bases 33, 33.

[0031] For the other shelves, as shown in FIG. 8(d), the brackets 3, 3 and the shelf boards 4 can be attached in the same manner as described above. In this manner, the knockdown rack 10 does not require tools for assembly. The knockdown rack 10 attached to the magnetic wall surface W in the above manner functions as a shelf on which items can be placed on the shelf boards 4. When disassembling the rack, the assembly steps are reversed, and no tools are required in this case either.

[0032] In the assembly rack 10, the fixed plate 1 has ribs 12, 12 formed on both the left and right sides of a single substrate 11. The shelf board 4 is supported horizontally by brackets 3, 3 on the left and right ribs 12, 12, respectively. Therefore, the fixed plate 1 basically only needs to be magnetically attached to the magnetic wall surface W once, reducing the time and labor required for assembly. Also, the number of parts required is reduced. When disassembling, the steps are reversed from those for assembly, and the fixed plate 1 only needs to be removed from the magnetic wall surface W once, reducing the time and labor required for the work. In addition, when removing the fixed plate 1 for adjusting the angle or disassembling it, as shown in Fig. 3(b), it can be partially bent and peeled off. In other words, instead of removing it all at once with a strong force, it can be peeled off gradually from one end with a relatively weak force, so even children or women who have relatively weak strength can easily remove it.

[0033] Each of the components of the assembly rack 10 described above can be modified in various ways.

[0034] [Modifications of the Fixing Plate] 9, 10, 11 and 12 are diagrams showing modified examples of the fixed plate 1 of the assembly rack 10. In FIG. For example, as shown in Fig. 9(a), a plurality of long through holes 13 may be provided at equal intervals L1 in the vertical direction Z of the rib 12, not in the top plate 122 but in the side plate 121. In other words, the holes have their axes parallel to the magnetic surface of the magnetic sheet 21. In this case, the hooks 32j of the bracket 3j are inserted into the long through holes 13 and dropped in to be locked. The shelf board 4 is then placed so as to span between the bases of the left and right brackets 3j, 3j.

[0035] 9(b), when a thick magnet sheet 21 is fixed to the substrate 11, the space S1 can be kept large even without providing the substrate 11 with ribs 12. In this example, the substrate 11 may be a flat plate, and the effort required for processing and forming the ribs 12 can be eliminated.

[0036] 9(c), the ribs 12 on the base plate 11 can be provided not only on the left and right but also on the top and bottom. In this case, shelf boards 4 having different widths can be arranged above and below.

[0037] 10, when a spacer 231 is sandwiched between the magnet sheet 21 and the substrate 11, the space S1 can be kept large even without providing the ribs 12 on the substrate 11. In this example, the substrate 11 may be a flat plate, and the effort required for processing and forming the ribs 12 can be eliminated.

[0038] If the spacer 231 is made of an elastic material, the spacer 231 can absorb shocks and reduce the displacement or falling of the assembly-type rack 10. For example, even if the magnetic wall surface W to which the assembly-type rack 10 is attached shakes due to an earthquake, the spacer 231 made of an elastic material can absorb the shock, mitigating the impact on the assembly-type rack 10 and reducing the displacement or falling. Conversely, when a heavy object is placed on the assembly-type rack 10, the spacer 231 made of an elastic material can absorb the shock when the heavy object is placed, reducing the displacement or falling of the assembly-type rack 10.

[0039] The elastic body is, for example, a flat rectangular parallelepiped having the same surface size as the surface area of ​​magnet sheet 21. It has a thickness of 1 mm to 5 mm and is made of, for example, foamed polystyrene, foamed urethane, a rubber sheet, etc. One surface is fixed to the non-magnetic surface of magnet sheet 21 via an adhesive, and the other surface is fixed to the rear surface of substrate 11 via an adhesive.

[0040] 11(a), the rib 12 has side walls 121 rising from the left and right ends of the substrate 11, and a top plate 122 extending from the top end of the side walls 121 toward the inside of the substrate 11 in parallel to the substrate 11. In FIG. 11(b), the rib 12 has side walls 121 rising from the left and right ends of the substrate 11, and a top plate 122 extending from the top end of the side walls 121 toward the outside of the substrate 11 in parallel to the substrate 11.

[0041] 11(a) and 11(b), a magnet sheet 21 is fixed to the surface of the substrate 11 on the non-protruding side of the ribs 12 by an adhesive.

[0042] 11(a) or 11(b), a gap is created under the end of the top plate 122, making it easier to peel off the fixing plate 1 by inserting a finger into this gap.

[0043] In FIG. 12, the magnet sheet 21 is overframed in such a way that it protrudes from the upper surface of the fixed plate 1. By making the magnet sheet 21 an overframe, the center of gravity of the magnetic surface is displaced upward. The ease with which the magnet sheet 21 peels off depends on the position of the object placed on the magnet sheet. Even if the weight is the same, the magnet sheet is more likely to peel off when an object is placed below the magnet sheet than when an object is placed on the upper end of the magnet sheet. For this reason, by displacing the center of gravity of the magnet sheet 21 upward with respect to the fixed plate 1, that is, by making it an overframe, it becomes possible to increase the weight that can be placed on the fixed plate 1.

[0044] By forming the magnet sheet 21 as an overframe, there is also an effect that when the fixing plate 1 is peeled off from the magnetic wall surface, the overframe portion can be pinched and the fixing plate 1 can be easily peeled off.

[0045] [Modifications of brackets and shelves] FIG. 13 is a diagram showing a modified example of the bracket 3 and the shelf board 4. In FIG. In FIG. 13(a), a magnetic sheet 221 is attached to the bracket 3 instead of through holes. Also, a magnetic sheet 221 is attached to the shelf board 4 instead of protrusions. The two magnetic sheets are magnetically attached to each other, making it possible to fix the shelf board 4 to the bracket 3. When installing the shelf board 4, it is possible to install the shelf board in a magnetically attached position, i.e., in an appropriate position, simply by sliding the shelf board 4 on the bracket 3. In other words, it is no longer necessary to align the protrusions with the through holes, which improves installation workability.

[0046] In FIG. 13(b), a bracket 3 and a shelf board 4 are integrally molded to form a bracket-attached shelf board 341. The shelf board with bracket 341 is made by cutting out a thin metal plate with a thickness of about 0.1 mm to 2 mm into a predetermined shape, similar to the substrate 11, and bending it between the shelf board 4 and the bracket 3. The bending process ensures the strength and load-bearing capacity of the shelf board 4. In FIG. 13(b), the left and right portions of the shelf board 4, i.e., between the bracket 3, are bent, but if the front and rear portions of the shelf board 4 are also bent, the strength and load-bearing capacity of the shelf board 4 can be further improved. The material of the bracket-attached shelf board 341 may be resin, wood, cardboard, or the like.

[0047] [Modification of bracket] 14 is a diagram showing a modified example of bracket 3. Bracket 3 is symmetrical with respect to frame 31 in the short direction of base 33. This eliminates the distinction between left and right bracket 3, making it possible to improve productivity and ease of installation. Furthermore, when two fixed plates 1 are arranged side by side with a gap between them, the shelf plate 4 can be placed between the opposing ribs 12 of the fixed plates 1 which are separate bodies.

[0048] Second Embodiment 15 is an external perspective view of the assembly rack 10A of the second embodiment, FIG. 16 is an exploded perspective view of the assembly rack 10A of the second embodiment, and FIG. 17 is a cross-sectional view taken along line BB in FIG.

[0049] 15 to 17, the assembly rack 10A includes a fixed plate 1A, posts 3A, shelf boards 4A, and post holders 5, and is detachably attached to a magnetic wall surface W by a magnetic sheet 21 provided on the fixed plate 1A. As with the assembly rack 10, the assembly rack 10A is also premised on being attached to the magnetic wall surface W by magnetic attraction, and no tools such as screwdrivers are required for assembly and disassembly.

[0050] Next, each of the components of the assembly rack 10A will be described in detail. Fig. 18 is a perspective view of the fixed plate 1A, Fig. 19 is a perspective view of the support 3A, and Fig. 20 is a perspective view of the support holder 5. Fig. 21 is a perspective view of the shelf board 4A, where (a) shows the front side and (b) shows the back side.

[0051] As shown in FIG. 18, the fixed plate 1A includes a substrate 11A and a magnet sheet . The substrate 11A is made of a thin rectangular metal plate having a thickness of about 0.1 mm to 2 mm, and has a pair of vertical walls 12A formed on both sides in the width direction X as shown in FIG. Each vertical wall 12A has an elongated shape that protrudes a predetermined height from the substrate surface and extends continuously in the up-down direction Z. More specifically, it is a single elongated plate wall that stands perpendicular to the substrate surface.

[0052] Each vertical wall 12A has a plurality of round through holes 13A bored at intervals L2, L3 in the vertical direction Z. The round through holes 13A are sized to allow the tips 33A, 34A (see FIG. 19) of the posts 3A to be inserted and locked. Such a substrate 11A is produced, for example, by bending both the left and right sides of a single rectangular thin metal plate in the width direction X to form vertical walls 12A, and then drilling a plurality of round through holes 13A in the vertical walls 12A. Alternatively, the order may be reversed, i.e., drilling the round through holes 13A first, and then bending the plate.

[0053] The metal used for the material of the thin metal plate is preferably one having soft magnetic properties, such as steel or ferritic stainless steel, for the same reasons as those for the substrate 11 of the first embodiment.

[0054] A magnet sheet 21 is fixed by adhesive to the non-protruding surface of the vertical wall 12A of the substrate 11A. The magnet sheet 21 is the same as that in the first embodiment, and therefore a description thereof will be omitted.

[0055] 19, the support 3A is substantially comb-shaped and includes a peripheral frame 31A and a shelf support bar 32A. Both the peripheral frame 31A and the shelf support bar 32A are made of a round metal bar material.

[0056] The peripheral frame 31A is generally arch-shaped, with the top and bottom portions each being generally L-shaped in plan view, and each having a linear tip portion 33A.

[0057] The shelf support bar 32A is substantially L-shaped in plan view and has a straight tip 34A. There are four shelf support bars 32A for each support column 3A. Each shelf support bar 32A protrudes into the recessed area of ​​the peripheral frame 31A from multiple locations at equal intervals L3 in the longitudinal direction of the vertical rod 311A ​​of the peripheral frame 31A. The interval L3 between adjacent shelf support bars 32A is set to the interval L3 between adjacent round through holes 13A in the vertical wall 12A.

[0058] The support 3A can be manufactured, for example, through a process of bending a long metal round bar into the shape of the peripheral frame 31A, a process of bending a plurality of short metal round bars into the shape of the shelf support bar 32A, and a process of welding the peripheral frame 31A and the shelf support bar 32A in the above-mentioned positional relationship and the vertical bar 311 of the peripheral frame 31A with the end of the shelf support bar 32A on the non-formed side of the tip 34A of the shelf support bar 32A in contact therewith. Note that the upper and lower halves of the support 3A from the center of the vertical bar 311 are symmetrical, and it is possible to use one that is upside down, so there is no need to change the type for left and right use.

[0059] The post holder 5 is a rectangular column having the same length as the vertical wall 12A of the base plate 11A, and has a number of round through holes 54 drilled at intervals L2 and L3 along the longitudinal direction, as shown in Fig. 20. The round through holes 54 are sized to fit the tip 34A of the shelf support bar 32A of the post 3A and the tip 33A of the peripheral frame 31A. The post holder 5 is made of wood, for example. The multiple round through holes 54 are drilled at positions corresponding to the round through holes 13A of the vertical wall 12A of the fixed plate 11A.

[0060] As shown in Fig. 21, the shelf board 4A is a rectangular board with a front side surface 41A as a placement surface, and is made of wood, synthetic resin, or metal. Fasteners 44A are provided near the four corners of the back side surface 42A of the shelf board 4A. The fasteners 44A are U-shaped in cross section and have hook-shaped bodies that fit into the shelf support bars 32A.

[0061] Next, the procedure for assembling the assembly rack 10A will be described. 22 and 23 are perspective views showing the assembly procedure of the assembly rack 10A.

[0062] First, as shown in Fig. 22(a), the fixed plate 1A is attached to the magnetic wall surface W. The attachment is performed in the same manner as in embodiment 1. That is, the left and right ends of the fixed plate 1A are held in the left and right hands, respectively, and with the magnetic surface of the magnetic sheet 21 facing the magnetic wall surface W, the horizontal side of the substrate 1A is kept horizontal, and the magnetic sheet 21 is placed against the magnetic wall surface W to be magnetically attached.

[0063] Next, as shown in Fig. 22(b), the support 3A is placed on the right side of the vertical wall 12A so that the axis of the tip ends 33A, 34A of the support 3A and the axis of the round through holes 13A, 13A of the left vertical wall 12A of the fixed plate 1A are approximately aligned, and in this state, the support 3A is slid toward the left vertical wall 12A. Then, as shown in Fig. 22(c), the tip ends 33A, 34A are inserted into the round through holes 13A, 13A.

[0064] Next, as shown in Fig. 22(d), the pillar holder 5 is placed on the outside of the left vertical wall 12A. At this time, the pillar holder 5 is placed so that the axis of the round through holes 54, 54 of the pillar holder 5 is approximately aligned with the axis of the tip ends 33A, 34A of the pillar 3A. In this state, the pillar holder 5 is slid toward the left vertical wall 12A, and the tip ends 33A, 34A are pressed into the round through holes 54, 54 and fixed in place, as shown in Fig. 23(a).

[0065] The right-side support pillar 3A is fixed to the right-side vertical wall 12A using the support pillar holder 5 in the same manner as the left-side support pillar 3A described above (see FIG. 23(b)).

[0066] Finally, attach shelf 4A. When installing, hold the left and right sides of the shelf board 4A with the placement surface 41A facing upwards in your left and right hands, and fit the fasteners 44A on both sides into the shelf support bar 32A at the desired height in the space between the two posts 3A, as shown in Figure 23(c). This causes the shelf board 4A to be horizontally supported between the two posts 3A.

[0067] The knockdown rack 10A attached to the magnetic wall surface W in the above-described manner functions as a shelf on which articles can be placed on the shelf boards 4A. For disassembly, the assembly steps are reversed.

[0068] In the assembly rack 10A, the fixed plate 1A has vertical walls 12A, 12A formed on both the left and right sides of a single substrate 11A. The shelf board 4A is supported horizontally by supports 3A, 3A on the left and right ribbed vertical walls 12A, 12A. Therefore, the task of magnetically attaching the fixed plate 1A to the magnetic wall surface W basically only needs to be done once, reducing the time and labor required for assembly work. In addition, the number of parts required is reduced. When disassembling, the procedure is reversed from that of assembly, and the fixing plate 1A needs to be removed from the magnetic wall W only once, reducing the time and labor required for the operation. In addition, when removing the fixed plate 1A for adjusting the angle or disassembling it, a portion of the fixed plate 1A can be bent and peeled off. In other words, instead of removing it all at once with a strong force, it can be peeled off gradually from the edge with a relatively weak force, making the removal work easy.

[0069] The assembly rack 10A can be used by arranging it in two levels, one above the other, as shown in Fig. 24(a), or by arranging it in two rows, one above the other, as shown in Fig. 24(b).

[0070] In addition, in the assembly rack 10A, the support holder 5 is disposed on the outer side of the vertical wall 12A of the fixed plate 1, but as shown in Fig. 25, the support holder 5 can also be disposed on the inner side of the vertical wall 12A. Fig. 25 is a perspective view showing a modified example of the assembly rack 10A, where (a) shows an assembled view and (b) shows an exploded view. In this modified example, by bridging the shelf board 4A between the left and right supports 3A, 3A, the left and right support holders 5, 5 are respectively constrained between the left and right vertical walls 12A, 12A and the supports 3A, 3A, so that the support holders 5, 5 are securely fixed.

[0071] [Modification of the support holder] Fig. 26 shows a modified example of the pillar holder 5. Fig. 26(a) is a cross-sectional view of a modified pillar holder 5A. The pillar holder 5A has a through hole 54A through which the tip 34A of the pillar 3A can pass, a groove 54C that fits with the vertical wall 12A at the end of the fixed plate 11A, and a bottomed hole 54B that fits with the tip 34A. The side plate of the pillar holder 5A on the side of the through hole 54A is shorter in height, in whole or in part, by the thickness of the fixed plate 11A, compared to the opposing side plate on the side of the bottomed hole 54B.

[0072] Fig. 26(b) is a cross-sectional view of the combination of the fixed plate 11A, the support 3A, and the support holder 5A. The support holder 5A is fitted in the groove 54C so as to straddle the vertical wall 12A of the fixed plate 11A. In addition, the tip 34A of the support 3A passes through the through hole 54A of the support holder 5A, passes through the through hole of the vertical wall 12A, and fits into the bottomed hole 54B of the support holder 5A. In this state, the support holder 5A is fixed by the vertical wall 12A of the fixed plate 11A and the tip 34A of the support 3A, so it will not fall off. In addition, the tip 34A is sealed by the bottomed hole 54B, so the tip 34A does not protrude outside the support holder 5A, improving the appearance.

[0073] FIG. 27 is a partial perspective view of the post holder 5A and the vertical wall 12A of the fixed plate 11A of the modified example. When the post holder 5A and the vertical wall 12A are fitted together, if the through holes are not aligned precisely, the tip 34A will not pass through. Therefore, a convex portion P1 is provided in the groove portion 54C of the post holder 5A, and a concave portion C1 is provided in the vertical wall 12A. As a result, when the post holder 5A is slid across the vertical wall 12A, the convex portion P1 and the concave portion C1 engage with each other, and the positions of the respective through holes (not shown) can be aligned, and the tip 34A of the post 3A can pass through. The portion of the post holder 5A that comes into contact with the fixed plate 11A is formed thin by the thickness of the fixed plate 11A. In this example, the groove portion 54C is a convex portion, and the vertical wall 12A is a concave portion, but the reverse may be true. In addition, the convex portion and the concave portion are not limited to a pair, and any shape that can be paired, that is, a so-called male-female shape, may be used.

[0074] Fig. 28 shows another modified example of the post holder. The longitudinal direction of the post holder 5B of this modified example is formed slightly longer than the longitudinal direction of the vertical wall 12A, and a groove portion is formed with the same length as the vertical wall 12A. When the post holder 5B is fitted into the vertical wall 12A, the positions of the respective through holes (not shown) are naturally aligned. This allows the tip 34A of the post 3A to pass through. The height of the portion of the side plate having the through hole of the post holder 5B that comes into contact with the fixed plate 11A is formed shorter than the side plate on the other side by the thickness of the fixed plate 11A.

[0075] FIG. 29 shows yet another modified example of the pillar holder, in which (a) shows a plan view of the main part of the modified pillar holder 550, and (b) shows an example of how the modified pillar holder 550 is used. The post holder 550 of the modified example has a groove M1 formed in the longitudinal direction of one surface as shown in FIG. 29(a). The groove M1 sandwiches the vertical walls 12A of the two fixed plates 1A. The post holder 550 has a plurality of round through holes 554 on two surfaces parallel to the groove M1. The round through holes 554 are sized to fit the tip 34A of the shelf support bar 32A of the post 3A and the tip 33A of the peripheral frame 31A. The post holder 550 is made of wood, for example. The plurality of round through holes 554 are drilled at positions corresponding to the respective round through holes 13A of the vertical walls 12A of the fixed plate 11A.

[0076] When installing, the two fixed plates 1A are magnetically attached to the magnetic wall surface W by the magnet sheet 21 so that the vertical walls 12A are adjacent to each other. Next, the two adjacent vertical walls 12A are fitted into the groove M1 of the support post holder 550. At this time, the positions of the through hole 13A of the vertical wall 12A and the through hole 554 of the support post holder 550 are aligned. In this state, the tip 34A of the shelf support bar 32A of the support post 3A (see FIG. 29(b)) is inserted into the through hole 554 and the through hole 13A. In this way, when the fixed plates 1A are used side by side as shown in FIG. 29(b), the two fixed plates 1A can be connected and fixed by one support post holder 550. In other words, the support post holder 550 can be shared by the two fixed plates 1A.

[0077] FIG. 30 is a diagram for explaining a modified example of the vertical wall. In this modification, the tip of the vertical wall 12A is bent perpendicularly outward relative to the fixed plate 1A, and after a predetermined length is secured, the vertical wall 12A is bent parallel to the vertical wall 12A. This improves the strength of the vertical wall 12A, making it possible to insert the tip of the support 3A directly through the vertical wall 12A and fix it there, which has the effect of eliminating the need for a support support 5.

[0078] 31 is a diagram showing a modified example of the support 3A. The tip of the modified support 3B is a hook similar to that of the bracket 3. The support 3B can be attached to the fixed plate 1B by inserting the hook into the long through hole of the rib 12 of the fixed plate 1B. This makes it possible to reduce the number of parts and improve the ease of installation.

[0079] Third Embodiment A third embodiment of the present invention will now be described. In the third embodiment, a wall magnet sheet using a magnet sheet as a wall material is used as the magnetic wall W. This wall magnet sheet is attached so that the magnetization lines are parallel to the horizontal direction. The magnetization lines refer to imaginary boundaries between one magnetic pole appearing on the surface of a multi-pole magnetized magnet sheet and the opposite poles on either side of it. In reality, these are the areas that turn white when a "Magneviewer" (registered trademark of Nichirei Magnet Co., Ltd.), a measuring tool that allows visual observation of magnetic patterns, is applied to the magnet sheet, and these are areas where the magnetic field in the vertical direction on the sheet surface is extremely weak or zero. As the magnet sheet 21 of the fixed portion 1 shown in the first embodiment, one having magnetized lines with the same pitch as the wall surface magnet sheet is selected.

[0080] When the magnet sheet 21 is attached to the magnetic wall W so that the magnetization lines of the magnet sheet 21 are approximately horizontal, the different poles of the striped magnetic poles of the magnet sheet 21 and the wall magnet sheet are magnetically attracted to each other. This allows the magnet sheet 21 to be fixed to the magnetic wall W in a straight state without tilting from the horizontal direction. Therefore, the labor required to attach the magnet sheet 21 while maintaining the horizontal state is reduced in the procedure shown in FIG. 8(a). Furthermore, since opposite poles are magnetically attracted to each other over the entire magnetic surface of the magnet sheet 21, fixing is performed with a stronger magnetic force than in the first embodiment.

[0081] Although the embodiments of the present invention have been described above, the embodiments disclosed above are merely examples, and the scope of the present invention is not limited to these embodiments. The scope of the present invention is indicated by the description of the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. In other words, the configuration, structure, shape, size, number, material, arrangement, and the like of each part or the entirety of the assembly racks 10, 10A can be modified as appropriate in accordance with the spirit of the present invention. [Industrial Applicability]
