[0016] FIGS. 1A to 8 and FIGS. 11A to 15B are views showing the first embodiment of the present disclosure.

Figures 11A to 15B show details of the contacts and additional contacts.

[0018] First, Figures 1A to 7 illustrate the wall-mounted storage device incorporating the tension support columns according to this disclosure.

[0019] As shown in Figures 1A to 7, the wall storage device 10 is arranged along a wall W that extends from the floor F to the ceiling C, and is used to place books or ornaments on it.

[0020] As shown in Figure 1A, such a wall-mounted storage device 10 comprises a pair of L-shaped tubular main support columns (hereinafter also referred to as L-shaped main support columns) 11, 11 provided along the wall surface W, and a pair of ladder-shaped side plates 20, 20 attached to each main support column 11, 11 and arranged parallel to each other. In this case, each ladder-shaped side plate 20, 20 extends from the corresponding main support column 11, 11 toward the front (see Figure 1A).

[0021] Furthermore, each ladder-shaped side plate 20 has a divisible upper ladder-shaped side plate 20A and a lower ladder-shaped side plate 20B, and the upper ladder-shaped side plate 20A and the lower ladder-shaped side plate 20B are connected by connecting bolts (connectors) 40, which will be described later.

[0022] Furthermore, the upper ladder-shaped side plate 20A of the ladder-shaped side plate 20 has a pair of side plate supports 21a, 22a and a plurality of stepped sections 23a that are stretched between the pair of side plate supports 21a, 22a.

[0023] Of these, the side plate support 21a is attached to the main support 11, and in this embodiment, it is welded to the main support 11.

[0024] Furthermore, the lower ladder-shaped side plate 20B of the ladder-shaped side plate 20 has a pair of side plate supports 21b and 22b, and a plurality of stepped sections 23b that are stretched between the pair of side plate supports 21b and 22b.

[0025] Of these, the side plate support 21b is attached to the main support 11, and in this embodiment, it is detachably attached to the main support 11 by connecting bolts 24.

[0026] Furthermore, multiple shelves 25 for placing books or ornaments are suspended between the corresponding steps 23a and 23b of the pair of ladder-shaped side plates 20, 20. In this case, each shelf 25 is provided with a pair of hooks 25a at its lateral ends when viewed from the front. Each shelf 25 is suspended and attached to the steps 23a and 23b via these hooks 25a.

[0027] Next, the pair of main support columns 11,11 will be described with reference to Figures 2 and 3. In a side view, each main support column 11,11 has an L-shape with a side portion 11a and a bottom portion 11b, and an adjuster 11c for adjusting the height position of the wall storage device 10 is provided on the lower surface of the bottom portion 11b (see Figure 3). Each main support column 11,11 is made of a rectangular tubular body and is made of stainless steel, steel, or aluminum.

[0028] Furthermore, each ladder-shaped side plate 20, 20 is placed on and supported on the bottom 11b of the L-shaped main support column 11, and the lower ladder-shaped side plates 20B, 20B of the ladder-shaped side plates 20, 20 are fixed to the bottom 11b by connecting bolts 32, as shown in Figures 1 and 4. In this case, the connecting bolts 32 are inserted into the insertion holes 32a of the lowest step 23b and tightened to the bottom 11b.

[0029] Furthermore, the upper ladder-shaped side plate 20A of each ladder-shaped side plate 20 is fixed to the main support 11 by welding the side plate support 21a to the main support 11 as described above, and the lower ladder-shaped side plate 20B is fixed to the main support 11 by attaching the side plate support 21b to the main support 11 with connecting bolts 24 (see Figure 1). In this embodiment, an example is shown in which the lower ladder-shaped side plate 20B is fixed to the main support 11 by attaching the side plate support 21b to the main support 11 with connecting bolts 24, but this is not limited to this, and for example, the side plate support 21b may be attached to the main support 11 by hooking the claw portion provided on the lower ladder-shaped side plate 20B side into a hole opened in the main support 11.

[0030] Furthermore, the pair of main support columns 11, 11 are connected to each other by a rear brace 30 provided behind the main support columns 11, 11, and this rear brace 30 is attached to each main support column 11, 11 by connecting bolts 31.

[0031] As shown in Figure 1A, inner tubes (also called sliding tubes) 12, 12 are slidably provided on the upper inner side of each main support column 11, 11, and contact fittings 13 that abut against the ceiling C are provided at the upper ends of these inner tubes 12, 12. In addition, each main support column 11 is provided with a fixing fitting 14 for fixing the inner tube 12 in a predetermined position, and the inner tube 12 can be fixed by this fixing fitting 14 when the contact fitting 13 of the inner tube 12 abuts against the ceiling C.

[0032] In the wall storage device 10 having such a configuration, the tension support column 1 according to this disclosure is composed of each main support column 11, 11, sliding pipes 12, 12 that are slidably provided on the upper part of the main support columns 11, 11 relative to the main support columns 11, 11, and contact fittings 13 that are provided at the upper ends of the sliding pipes 12, 12 and come into contact with the ceiling C (see Figures 1A and 1B).

[0033] Next, the contact fitting 13 for the tension support column 1 will be described with reference to Figures 11A to 12E. As described above, the contact fitting 13 contacts the ceiling C and transmits the external force applied to the tension support column 1 to the ceiling C, thereby supporting the tension support column 1.

[0034] As shown in Figures 11A to 11C, the contact device 13 has a contact device body 51 and a contact surface 53 provided on the contact device body 51 that contacts the ceiling C.

[0035] In this embodiment, both the contact body 51 and the contact surface 53 have an L-shape when viewed from above. The contact body 51 of the contact 13 is made of polypropylene (PP) and is attached to the sliding pipe 12 via mounting screws 55. Furthermore, the contact surface 53 is made of silicone.

[0036] Both the silicone contact surface 53 and the polypropylene (PP) contact body 51 are L-shaped in plan view, but the contact surface 53 is slightly smaller than the contact body 51. In a plan view of the contact, the contact body 51 is slightly visible as a band, for example, 1.5 to 2 mm wide, around the outer circumference of the contact surface 53 (see Figures 11A and 11B).

[0037] As shown in Figures 11A to 11C, the contact surface 53 of the contact device 13 has a square portion 53a and a pair of extension portions 53b1 and 53b2 extending from two adjacent sides of the square portion 53a in directions 90° apart from each other, so that the contact surface 53 as a whole is L-shaped. In this case, the square portion 53a of the contact device 13 is square-shaped, and each extension portion 53b1 and 53b2 is rectangular-shaped. However, each extension portion 53b1 and 53b2 may also be square-shaped.

[0038] Furthermore, depending on the orientation of the contact fitting 13, the extensions 53b1 and 53b2 of the contact fitting 13 protrude laterally relative to the mounting screw 55 (see Figures 12A to 12D).

[0039] Furthermore, the mounting screw 55 provided on the contact fitting 13 is positioned at the center of the square portion 53a of the contact surface 53, and as a result, the sliding tube 12 connected to the mounting screw 55 is also positioned at the center of the square portion 53a of the contact surface 53 (see Figure 12E). In this case, the mounting screw 55 does not necessarily have to be positioned at the center of the square portion 53a; for example, the mounting screw 55 may be provided on the diagonal line L3 connecting the outer corner 53a1 and the inner corner 53a2 of the square portion 53a, or at any position within the square portion 53a. By providing the mounting screw 55 at the center of the square portion 53a, on the diagonal line L3 connecting the outer corner 53a1 and the inner corner 53a2 of the square portion 53a, or at any position within the square portion 53a, the force applied to the main support column 11 can be reliably transmitted to the contact fitting 13.

[0040] According to this embodiment, the contact surface 53 of the contact fitting 13 has a square portion 53a and a pair of extension portions 53b1 and 53b2, forming an L-shape in plan view. The mounting screw 55 and the sliding tube 12 are positioned at the center of the square portion 53a. As a result, the external force applied to the bracing column 1 is reliably transmitted to the ceiling C, and the contact fitting 13 can reliably support the bracing column 1.

[0041] For example, as shown in Figures 11A and 11A to 11C, when the contact device 13 is brought into contact with the ceiling C, both external forces applied to the bracing column 1 in the L direction and in the L1 direction perpendicular to the L direction are transmitted to the ceiling C in the same way, and the bracing column 1 can be reliably supported by the contact device 13.

[0042] On the other hand, as shown in Figure 11D, in the comparative example where the contact fitting 13 is elongated (strip-shaped), it is possible to transmit the external force in the L direction applied to the bracing column 1 to the ceiling C and support the bracing column 1, but the external force in the L1 direction perpendicular to the L direction cannot be sufficiently transmitted to the ceiling C, and it is possible that the contact fitting 13 may come off the ceiling C.

[0043] As described above, according to this embodiment, regardless of the direction of the external force, the external force applied to the bracing column 1 is transmitted to the ceiling C, and the bracing column can be reliably supported by the contact device 13.

[0044] Furthermore, as described above, each main support column 11, 11 has an adjuster 11c at its bottom 11b for adjusting its height, and an additional contact 63 with the same configuration as the contact 13 attached to the top of the main support column 11 is placed between each adjuster 11c and the bottom surface F (see Figures 13A and 13B).

[0045] As shown in Figures 13A and 13B, the additional contact device 63 has an additional contact device body 71 and an additional contact surface 73 provided on the additional contact device body 71 that contacts the floor surface F.

[0046] In this embodiment, both the additional contact body 71 and the additional contact surface 73 have an L-shape in plan view. The additional contact body 71 of the additional contact 63 is made of polypropylene (PP) and is attached to the adjuster 11c described above via mounting screws 75. Furthermore, the additional contact surface 73 is made of silicone.

[0047] Both the silicone additional contact surface 73 and the polypropylene (PP) additional contact body 71 are L-shaped in plan view, but the additional contact surface 73 is slightly smaller than the additional contact body 71, and the additional contact body 71 is slightly visible as a band, for example, 1.5 to 2 mm wide, around the outer circumference of the additional contact surface 73 (see Figure 13B).

[0048] As shown in Figures 13A and 13B, the additional contact surface 73 of the additional contact device 63 has an additional square portion 73a and a pair of additional extension portions 73b1 and 73b2 extending from two adjacent sides of the additional square portion 73a in directions 90° apart from each other, so that the additional contact surface 73 as a whole is L-shaped. In this case, the additional square portion 73a of the additional contact device 63 is square-shaped, and each additional extension portion 73b1 and 73b2 is rectangular-shaped. However, each additional extension portion 73b1 and 73b2 may also be square-shaped.

[0049] Furthermore, depending on the orientation of the contact fitting 13, the additional extensions 73b1 and 73b2 of the additional contact fitting 63 protrude laterally relative to the mounting screw 75 (see Figures 13A and 13B).

[0050] Furthermore, the mounting screw 75 provided on the additional contact fitting 63 is positioned at the center of the additional square portion 73a of the additional contact surface 73, and as a result, the adjuster 11c connected to the mounting screw 75 is also positioned at the center of the additional square portion 73a of the additional contact surface 73 (see Figure 13A). In this case, the mounting screw 75 does not necessarily have to be positioned at the center of the additional square portion 73a; for example, the mounting screw 75 may be provided on the diagonal line L4 connecting the outer corner 73a1 and the inner corner 73a2 of the additional square portion 73a, or at any position within the additional square portion 73a. By providing the mounting screw 75 at the center of the additional square portion 73a, on the diagonal line L4 connecting the outer corner 73a1 and the inner corner 73a2 of the additional square portion 73a, or at any position within the square portion 73a, the force applied to the main support column 11 can be reliably transmitted to the additional contact fitting 63.

[0051] According to this embodiment, the additional contact surface 73 of the additional contact fitting 63 has an additional square portion 73a and a pair of additional extension portions 73b1 and 73b2, forming an L-shape in plan view. The mounting screw 75 and adjuster 11c are positioned at the center of the additional square portion 73a. As a result, the external force applied to the tension support column 1 is transmitted to the floor surface F, and the tension support column 1 can be reliably supported by the additional contact fitting 63.

[0052] For example, as shown in Figure 13A, when the additional contact device 63 is brought into contact with the floor surface F, both external forces applied to the bracing column 1 in the L direction and in the L1 direction perpendicular to the L direction are transmitted to the floor surface F in the same way, and the bracing column 1 can be reliably supported by the contact device 13.

[0053] On the other hand, in the comparative example where the additional contact device 63 is elongated (strip-shaped), it is possible to support the support column 1 by transmitting the external force in the L direction applied to the support column 1 to the floor surface F, but it is not possible to adequately transmit the external force in the L1 direction, which is perpendicular to the L direction, to the floor surface F (see Figure 11D).

[0054] As described above, according to this embodiment, the external force applied to the tension support column 1 is reliably transmitted to the floor surface F by the additional contact device 63, and the tension support column can be supported by the additional contact device 63.

[0055] Next, the connection structure between the upper ladder-shaped side plate 20A and the lower ladder-shaped side plate 20B of the ladder-shaped side plate 20 will be explained with reference to Figures 4 to 6.

[0056] As shown in Figures 1A and 4 to 6, the upper ladder-shaped side plate 20A of the ladder-shaped side plate 20 has a pair of side plate supports 21a, 22a and a plurality of steps 23a stretched between the pair of side plate supports 21a, 22a, and the lower ladder-shaped side plate 20B has a pair of side plate supports 21b, 22b and a plurality of steps 23b stretched between the pair of side plate supports 21b, 22b. Of these, the lowest step 23a of the upper ladder-shaped side plate 20A is formed flat along the horizontal direction in the portion close to the side plate support 22a side, forming an upper flat portion 41 (see Figures 5 and 6). Also, as shown in Figures 4 and 6, a horizontal connecting rod 42 is provided at the top of the lower ladder-shaped side plate 20B, extending horizontally from the side plate support 22b in the same direction as the lowest step 23a of the upper ladder-shaped side plate 20A.

[0057] Unlike the other stepped sections 23b, this horizontal connecting rod 42 does not extend from the side plate support 22b towards the side plate support 21a, but extends to the upper flat section 41 of the upper ladder-shaped side plate 20A and terminates there. The horizontal connecting rod 42 of the lower ladder-shaped side plate 20B is provided with a lower flat section 42a that is formed horizontally and flat at a position corresponding to the upper flat section 41 of the upper ladder-shaped side plate 20A.

[0058] As shown in Figure 6, a connecting bolt (connector) 40 is fastened between the upper flat portion 41 of the upper ladder-shaped side plate 20A and the lower flat portion 42a of the lower ladder-shaped side plate 20B, thereby connecting the upper ladder-shaped side plate 20A and the lower ladder-shaped side plate 20B to each other.

[0059] Next, we will explain how to assemble the wall storage device 10, which has the above configuration.

[0060] First, prepare the pair of main support columns 11, 11 described above, and install these main support columns 11, 11 along the wall surface W.

[0061] In this case, an inner tube 12 with a fitting 13 attached is inserted into the upper part of each main support column 11, 11 beforehand. Also, an upper ladder-shaped side plate 20A is fixed to each main support column 11, 11 beforehand by welding the side plate support 21a of the upper ladder-shaped side plate 20A to the main support column 11. Furthermore, the main support columns 11, 11 are placed on the bottom surface F by the adjuster 11c at the bottom 11b and an additional fitting 63 provided below the adjuster 11c.

[0062] Next, the lower ladder-shaped side plates 20B are placed on the bottom 11b of each main support column 11, 11, and the side plate supports 21b of the lower ladder-shaped side plates 20B are fixed to the main support columns 11 with connecting bolts 24. At this time, the lowest step 23b of the lower ladder-shaped side plate 20B is on the bottom 11b of the main support column 11, and the lowest step 23b of the lower ladder-shaped side plate 20B and the bottom 11b of the main support column 11 are fixed with connecting bolts 32.

[0063] Next, a rear brace 30 is installed behind the pair of main support columns 11, 11, and this rear brace 30 is fixed to the rear surface of the main support columns 11, 11 with connecting bolts 31. In this way, each of the main support columns 11, 11 can be firmly fixed by the rear brace 30.

[0064] Subsequently, the upper flat portion 41 of the upper ladder-shaped side plate 20A and the lower flat portion 42a of the lower ladder-shaped side plate 20B are connected with connecting bolts 40. This allows the upper ladder-shaped side plate 20A and the lower ladder-shaped side plate 20B to be firmly fixed together.

[0065] Next, the inner pipe 12, which is located at the top of the main support column 11, is extended upward, and the contact fitting 13 of the inner pipe 12 is brought into contact with the ceiling C. At this position, the inner pipe 12 is fixed to the main support column 11 by the fixing fitting 14. This allows the main support column 11 to be sandwiched between the bottom surface F and the ceiling C, and the main support column 11 can be firmly fixed in place.

[0066] Subsequently, a shelf board 25 is placed between the desired steps 23a and 23b of the ladder-shaped side boards 20 fixed to the pair of main support columns 11, 11. In this case, the shelf board 25 is hooked onto the steps 23a and 23b via hooks 25a.

[0067] In this way, the wall-mounted storage device 10 is obtained. Of this wall-mounted storage device 10, the ladder-shaped side plates 20 and shelves 25 are made entirely or partially from stainless steel, steel, or aluminum. Also, as described above, each main support column 11, 11 is made from stainless steel, steel, or aluminum.

[0068] Next, the effects of the contact fittings 13 attached to the upper part of each sliding pipe 12 and the additional contact fittings 63 attached to the lower part of each main support column will be described below.

[0069] As shown in Figure 1A, each contact fitting 13 attached to the upper part of each sliding pipe 12 has a contact fitting body 51 and a contact surface 53, and the contact fitting 13 is arranged so that a square portion 53a and one extended portion 53b1 extend in a direction perpendicular to the wall surface W.

[0070] The square portion 53a and the other extension portion 53b2 of the connector 13 extend along a direction L parallel to the wall surface W.

[0071] Generally, when a wall storage device 10 is arranged such that the shelves 25 extend along a direction L parallel to the wall surface W, an external force in the direction L parallel to the wall surface W is applied to the wall storage device 10 when the building shakes along the wall surface W due to an earthquake or the like. As described above, the contact device 13 is arranged so that the square portion 53a and the other extended portion 53b2 extend parallel to the wall surface W, so the contact surface 53 extends for a relatively long distance along the direction L parallel to the wall surface W. As a result, even when an external force in the direction L parallel to the wall surface W acts on the wall storage device 10, the square portion 53a extending in the direction L parallel to the wall surface W and the other extended portion 53b2 of the contact surface 53 can effectively transmit this external force to the ceiling C.

[0072] Furthermore, even when an external force is applied to the wall storage device 10 along a direction L1 perpendicular to the wall surface W, the square portion 53a extending along the direction L1 perpendicular to the wall surface W and the other extension portion 53b1 of the contact surface 53 can effectively transmit this external force to the ceiling C. In other words, when an external force is applied to the wall storage device 10 along a direction L1 perpendicular to the wall surface W, the square portion 53a extending along the direction L1 perpendicular to the wall surface W and the other extension portion 53b1 reliably engage with the ceiling C.

[0073] Therefore, when an external force is applied to the wall storage device 10 along a direction L1 perpendicular to the wall W, this external force can be reliably transmitted to the ceiling C, and the contact device 13 will not detach from the ceiling C.

[0074] Similarly, the additional contact device 63 has an additional contact device body 71 and an additional contact surface 73, and the additional contact device 63 is arranged so that the additional square portion 73a and one additional extension portion 73b1 extend in a direction L perpendicular to the wall surface W. The additional square portion 73a and the other additional extension portion 73b2 of the additional contact device 63 extend along a direction L parallel to the wall surface W.

[0075] Generally, when a wall-mounted storage device 10 is arranged such that the shelves 25 extend parallel to the wall surface W, if the building shakes along the wall surface W due to an earthquake or the like, an external force L in a direction parallel to the wall surface W is applied to the wall-mounted storage device 10. As described above, the additional contact piece 63 is arranged so that the additional square portion 73a and the other additional extension portion 73b2 extend parallel to the wall surface W, so the additional contact surface 73 extends for a relatively long distance along the direction L parallel to the wall surface W. As a result, even if an external force L in a direction parallel to the wall surface W acts on the wall-mounted storage device 10, the additional square portion 73a extending in the direction L parallel to the wall surface W and the other additional extension portion 73b2 of the additional contact surface 73 can effectively transmit this external force to the floor surface F.

[0076] Furthermore, even when an external force is applied to the wall storage device 10 along a direction L1 perpendicular to the wall surface W, the additional square portion 73a extending along the direction L1 perpendicular to the wall surface W and the additional extension portion 73b1 of the additional contact surface 73 can effectively transmit this external force to the floor surface F. Also, when an external force is applied to the wall storage device 10 along a direction L1 perpendicular to the wall surface W, the additional square portion 73a extending along the direction L1 perpendicular to the wall surface W and the additional extension portion 73b1 reliably engage with the floor surface F.

[0077] Therefore, when an external force is applied to the wall storage device 10 along a direction L1 perpendicular to the wall surface W, this external force can be reliably transmitted to the floor surface F, and the additional contact device 63 will not come off the floor surface F.

[0078] Next, the installation structure of the wall storage device 10 will be explained with reference to Figures 14A to 15C. As described above, the L-shaped contact piece 13 of the wall storage device 10 is arranged such that the square portion 53a and one extension portion 53b1 extend along a direction L1 perpendicular to the wall surface W, and the square portion 53a and the other extension portion 53b2 extend along a direction L parallel to the wall surface W.

[0079] In addition, the additional contact fitting 63, which has an L-shape in plan view, is arranged such that the additional square portion 73a and one additional extension portion 73b1 extend along a direction L1 perpendicular to the wall surface W, and the additional square portion 73a and the other additional extension portion 73b2 extend along a direction L parallel to the wall surface W.

[0080] Therefore, as shown in Figures 14A, 15A to 15C, even when a pair of wall-mounted storage devices 10 are placed close to each other, the contact devices 13 or additional contact devices 63 do not interfere with each other, and the pair of wall-mounted storage devices 10 can be placed as close together as possible (see Figures 14A, 15A to 15C).

[0081] Furthermore, according to this embodiment, the square portion 53a and the other extension portion 53b2 of the abutment 13 extend along the direction L parallel to the wall surface W, and the additional square portion 73a and the other additional extension portion 73b2 of the additional abutment 63 extend along the direction L parallel to the wall surface W. Therefore, as shown in Figure 14A, in the left wall storage device 10, by bringing the left abutment 13 into contact with the corner portion W1 between the wall surfaces W, the main support column 11 can be positioned near the corner portion W1. Therefore, when positioning the wall storage device 10, no dead space is created in the corner portion W1 between the wall surfaces W.

[0082] Furthermore, according to this embodiment, as shown in Figure 14A, in the left-side wall storage device 10, the additional abutment 63 at the rear left can be positioned in the corner W1 between the two walls W. Therefore, when positioning the wall storage device 10, no dead space is created in the corner W1 between the two walls W.

[0083] In contrast, in the case of a comparative example (see Figure 14B), where the contact fitting 13 is not L-shaped in a plan view but has a rectangular contact surface that extends in an elongated (strip-like) shape in the direction L parallel to the wall surface W, if a pair of wall storage devices 10 are placed close to each other, the contact fittings 13 will interfere with each other, so it is necessary to place the pair of wall storage devices 10 at a certain distance apart.

[0084] Furthermore, in the comparative example shown in Figure 14B, since the abutment 13 extends in an elongated shape in the direction L parallel to the wall surface W, if the abutment 13 is placed at the corner W1 between two wall surfaces W, the main support column 11 will be separated from the corner W1, resulting in dead space at the corner W1 between the two wall surfaces W.

[0085] As described above, according to this embodiment, the ladder-shaped side plate 20, which consists of an upper ladder-shaped side plate 20A and a lower ladder-shaped side plate 20B, is mounted on the bottom 11b of the L-shaped main support column 11. Therefore, the ladder-shaped side plate 20 can be stably held by the main support column 11, and the ladder-shaped side plate 20 will not fall or detach from the main support column 11. Furthermore, by fixing the ladder-shaped side plate 20 to the side 11a and bottom 11b of the main support column 11, the ladder-shaped side plate 20 can be firmly fixed to the main support column 11. As a result, even if the stylish ladder-shaped side plate 20 is made of thin material which has high design quality but low strength, the ladder-shaped side plate 20 will not deform even if reinforcing structures such as truss structures or bracing structures are not provided at the top or bottom of the ladder-shaped side plate 20. Therefore, compared to cases where reinforcing structures such as truss structures or bracing structures are provided at the top or bottom of the ladder-shaped side plate 20, it is possible to eliminate dead space caused by the provision of reinforcing structures, and to effectively utilize the top and bottom of the ladder-shaped side plate 20.

[0086] Furthermore, the inner tube 12 provided on the main support column 11 is extended upwards, and the contact fitting 13 is brought into contact with the ceiling C, and at this position the inner tube 12 is fixed to the main support column 11 by the fixing fitting 14. In this way, the main support column 11 can be sandwiched between the bottom surface F and the ceiling C, and the main support column 11 can be firmly fixed along the wall surface W.

[0087] Furthermore, the ladder-shaped side plate 20 has an upper ladder-shaped side plate 20A and a lower ladder-shaped side plate 20B that are separable from each other, and the upper ladder-shaped side plate 20A and the lower ladder-shaped side plate 20B are connected by tightening connecting bolts 40 between the upper flat portion 41 and the lower flat portion 42a. The lower ladder-shaped side plate 20B is also removable from the main support column 11. For this reason, as will be described later, only the lower ladder-shaped side plate 20B can be removed from the main support column 11.

[0088] Furthermore, the horizontal connecting rod 42 of the lower ladder-shaped side plate 20B does not extend between the pair of side plate supports 21a and 22a, as does the lowest step portion 23a of the upper ladder-shaped side plate 20A, but terminates at the upper flat portion 41 of the upper ladder-shaped side plate 20A. As a result, the lowest step portion 23a of the upper ladder-shaped side plate 20A extends horizontally from the side plate support 22a to form the upper flat portion 41 and then extends further to the side plate support 21a. Consequently, compared to the case where the lowest step portion 23a of the upper ladder-shaped side plate 20A extends overlapping with the step portion 23b of the lower ladder-shaped side plate 20B, the lowest step portion 23a of the upper ladder-shaped side plate 20A extends independently, thus maintaining and improving the aesthetic appearance.

[0089] In the embodiment shown in Figure 1A, a shelf board 25 for placing books or ornaments is suspended between the steps 23a and 23b of a pair of ladder-shaped side plates 20, 20 by hooking its hooks 25a onto the steps 23a and 23b. However, the invention is not limited to this, as shown in Figure 1B, a hanging rod 26 having hooks 26a can be suspended between the steps 23a and 23b, and desired items, such as clothing like hats and scarves, or calendars, can be hung from this hanging rod 26.

[0090] Next, Figure 8 will describe another method of assembling the wall storage device 10.

[0091] The assembly method for the wall storage device 10 shown in Figure 8 is the same as that of the wall storage device 10 shown in Figure 1A, with the pair of lower ladder-shaped side plates 20B removed, and the other components are the same as those of the wall storage device 10 shown in Figure 1.

[0092] In Figure 8, the same reference numerals are used for parts identical to those in the wall storage device 10 shown in Figure 1, and detailed explanations are omitted. In Figure 1, the connecting bolt 40 provided between the upper flat portion 41 of the upper ladder-shaped side plate 20A and the lower flat portion 42a of the lower ladder-shaped side plate 20B is removed, and the connecting bolt 32 provided between the lowest step portion 23b of the lower ladder-shaped side plate 20B and the bottom of the main support column 11 is removed.

[0093] Next, remove the lower ladder-shaped side plates 20B, 20B from the pair of main support columns 11.

[0094] Subsequently, a lateral brace 45 is installed between the front portion of the upper ladder-shaped side plates 20A, 20A shown in Figure 8 (located in the range of one-quarter to one-half of the way from the front end) and the upper position of the corner 11d of the side portion 11a and bottom portion 11b of the main support column 11 (an intermediate position on the side portion 11a corresponding to the lower ladder-shaped side plate 20B). This allows the main support column 11 to effectively support the gravitational force acting on the upper ladder-shaped side plates 20A via the lateral brace 45. In Figure 8, the upper end of the lateral brace 45 is fixed to the upper ladder-shaped side plates 20A, 20A by attaching it to the upper flat portion 41 provided on the lowest step portion 23b of the upper ladder-shaped side plates 20A, 20A with a connecting bolt 40. Furthermore, a flat lower mounting bracket 45b, formed by press working, is integrally provided with the lateral brace 45 at the lower end of the side plate brace 45, and this flat lower mounting bracket 45b is fixed to the side portion 11a of the main support column 11 by mounting bolts 45B.

[0095] According to this assembly method, by removing the lower ladder-shaped side plates 20B, 20B from the pair of main support columns 11, the lower ladder-shaped side plates 20B, 20B and the corresponding shelf boards 25 can also be removed. This frees up the area occupied by the lower ladder-shaped side plates 20B, 20B and the corresponding shelf boards 25, allowing for the effective use of this freed-up area by storing a TV or other equipment in it.

[0096] <Second Embodiment> Next, a second embodiment of this disclosure will be described with reference to Figures 9 and 10.

[0097] The second embodiment shown in Figures 9 and 10 is provided with three main support columns 11, 11, 11 instead of a pair of main support columns 11, 11. Other components are the same as those in the first embodiment shown in Figures 1A to 8, and the same reference numerals are used for those parts, and a detailed explanation is omitted.

[0098] As shown in Figures 9 and 10, the wall storage device 10 is arranged along a wall W that extends from the floor F to the ceiling C, and is used to place books or ornaments on it.

[0099] As shown in Figures 9 and 10, such a wall-mounted storage device 10 comprises three L-shaped tubular main support columns 11, 11, 11 provided along the wall W, and three ladder-shaped side plates 20, 20, 20 attached to each main support column 11, 11, 11 and arranged parallel to each other. In this case, each ladder-shaped side plate 20, 20, 20 extends from the corresponding main support column 11, 11, 11 toward the front (see Figure 9).

[0100] Furthermore, each ladder-shaped side plate 20 has a divisible upper ladder-shaped side plate 20A and a lower ladder-shaped side plate 20B, and the upper ladder-shaped side plate 20A and the lower ladder-shaped side plate 20B are connected by connecting bolts (connectors) 40, which will be described later.

[0101] Furthermore, the upper ladder-shaped side plate 20A of the ladder-shaped side plate 20 has a pair of side plate supports 21a, 22a and a plurality of stepped sections 23a that are stretched between the pair of side plate supports 21a, 22a.

[0102] Of these, the side plate support 21a is attached to the main support 11, and in this embodiment, it is welded to the main support 11.

[0103] Furthermore, the lower ladder-shaped side plate 20B of the ladder-shaped side plate 20 has a pair of side plate supports 21b and 22b, and a plurality of stepped sections 23b that are stretched between the pair of side plate supports 21b and 22b.

[0104] Of these, the side plate support 21b is attached to the main support 11, and in this embodiment, it is detachably attached to the main support 11 by connecting bolts 24.

[0105] Furthermore, multiple shelves 25 are stretched between the corresponding steps 23a and 23b of adjacent pairs of ladder-shaped side plates 20, 20. In this case, each shelf 25 is provided with a pair of hooks 25a at its lateral ends when viewed from the front. Each shelf 25 is then stretched and attached to the steps 23a and 23b via these hooks 25a (see Figure 9).

[0106] Next, the three main support columns 11,11,11 will be described. In a side view, each main support column 11,11,11 has an L-shape with a side portion 11a and a bottom portion 11b. An adjuster 11c is provided on the underside of the bottom portion 11b to contact the floor surface F and adjust the height position of the wall storage device 10 (see Figure 9). Each main support column is made of a square cylindrical body and is made of stainless steel, steel, or aluminum.

[0107] Each ladder-shaped side plate 20, 20, 20 is placed on and supported on the bottom 11b of the L-shaped main support column 11, and the ladder-shaped side plates 20, 20, 20 are fixed to the bottom 11b by connecting bolts 32. In this case, the connecting bolts 32 are inserted into the insertion holes 32a of the lowest step 23b and tightened to the bottom 11b.

[0108] Furthermore, the upper ladder-shaped side plate 20A of each ladder-shaped side plate 20 is fixed to the main support 11 by welding the side plate support 21a to the main support 11 as described above, and the lower ladder-shaped side plate 20B is fixed to the main support 11 by attaching the side plate support 21b to the main support 11 with connecting bolts 24. In this embodiment, an example is shown in which the lower ladder-shaped side plate 20B is fixed to the main support 11 by attaching the side plate support 21b to the main support 11 with connecting bolts 24, but this is not limited to this, and for example, the side plate support 21b may be attached to the main support 11 by hooking the claw portion provided on the lower ladder-shaped side plate 20B side into a hole opened in the main support 11.

[0109] Furthermore, adjacent pairs of main support columns 11, 11 are connected to each other by a rear brace 30 provided behind the main support columns 11, 11, and this rear brace 30 is attached to each main support column 11, 11 by connecting bolts 31.

[0110] As shown in Figure 9, inner tubes 12, 12, 12 are slidably mounted on the upper part of each main support column 11, 11, 11, and contact devices 13, 13A that abut against the ceiling C are provided at the upper ends of these inner tubes 12, 12, 12. In addition, each main support column 11 is provided with a fixing device 14 for fixing the inner tube 12 in a predetermined position, and the inner tube 12 can be fixed by this fixing device 14 when the contact devices 13, 13A of the inner tube 12 abut against the ceiling C.

[0111] Furthermore, as shown in Figures 9 and 10, the contact devices 13, 13 provided on the upper parts of the two end main support columns 11, 11, 11 of the three main support columns 11, 11, 11 have the same structure as the contact device 13 in the first embodiment shown in Figures 1A to 7, 11A to 12D, and 14A to 15B, and are arranged in the same orientation as the contact device 13 in the first embodiment.

[0112] In other words, the contact devices 13, 13 provided on the upper part of the main support columns 11, 11 at both ends are L-shaped in plan view, and have an L-shaped contact device body 51 and an L-shaped contact surface 53 in plan view.

[0113] On the other hand, the abutment fitting 13A provided on the upper part of the central main support column 11 is elongated (strip-shaped), and the abutment fitting 13A is positioned to extend along a direction parallel to the wall surface W (direction L).

[0114] Furthermore, adjusters 11c are provided at the lower part of the main support columns 11, 11 at both ends, and an additional abutment 63 having the same structure as the additional abutment 63 in the first embodiment is provided between the adjuster 11c and the floor surface F, and this additional abutment 63 is arranged in the same orientation as the additional abutment 63 in the first embodiment (see Figures 13A and 13B).

[0115] In other words, the additional contact devices 63 attached to the adjusters 11c of the main support columns 11, 11 at both ends are L-shaped in plan view and consist of an additional contact device body 71 which is L-shaped in plan view and an additional contact surface 73 which is L-shaped in plan view.

[0116] On the other hand, an additional abutment 63A is provided at the lower part of the central main support column 11 via an adjuster 11c. This additional abutment 63A is elongated (strip-shaped) and extends along a direction parallel to the wall surface (L direction).

[0117] Incidentally, in the second embodiment shown in Figures 9 and 10, the connection structure between the upper ladder-shaped side plate 20A and the lower ladder-shaped side plate 20B of the ladder-shaped side plate 20 is substantially the same as that of the first embodiment shown in Figures 1A, 4 to 6.

[0118] Specifically, as shown in Figures 1A and 4 to 6, the upper ladder-shaped side plate 20A of the ladder-shaped side plate 20 has a pair of side plate supports 21a, 22a and a plurality of steps 23a stretched between the pair of side plate supports 21a, 22a, while the lower ladder-shaped side plate 20B has a pair of side plate supports 21b, 22b and a plurality of steps 23b stretched between the pair of side plate supports 21b, 22b. Of these, the lowest step 23a of the upper ladder-shaped side plate 20A is formed flat along the horizontal direction in the portion close to the side plate support 22a, forming an upper flat portion 41. Furthermore, a horizontal connecting rod 42 is provided at the top of the lower ladder-shaped side plate 20B, extending horizontally from the side plate support 22b in the same direction as the lowest step 23a of the upper ladder-shaped side plate 20A.

[0119] Unlike the other stepped sections 23b, this horizontal connecting rod 42 does not extend from the side plate support 22b towards the side plate support 21a, but extends to the upper flat section 41 of the upper ladder-shaped side plate 20A and terminates there. The horizontal connecting rod 42 of the lower ladder-shaped side plate 20B is provided with a lower flat section 42a that is formed horizontally and flat at a position corresponding to the upper flat section 41 of the upper ladder-shaped side plate 20A.

[0120] As shown in Figure 6, a connecting bolt (connector) 40 is fastened between the upper flat portion 41 of the upper ladder-shaped side plate 20A and the lower flat portion 42a of the lower ladder-shaped side plate 20B, thereby connecting the upper ladder-shaped side plate 20A and the lower ladder-shaped side plate 20B to each other.

[0121] Next, we will explain how to assemble a wall storage device with the above configuration.

[0122] First, prepare the three main support columns 11, 11, 11 mentioned above, and install these main support columns 11, 11, 11 along the wall surface W.

[0123] In this case, an inner tube 12 with a fitting 13 attached is pre-inserted into the upper part of each main support column 11,11,11. Furthermore, an upper ladder-shaped side plate 20A is pre-attached to each main support column 11,11,11 by welding the side plate support 21a of the upper ladder-shaped side plate 20A to the main support column 11. The main support columns 11,11,11 are then placed on the bottom surface F by the adjuster 11c at the bottom 11b and an additional fitting 63 provided below the adjuster 11c.

[0124] Next, the lower ladder-shaped side plates 20B are placed on the bottom 11b of each main support column 11, 11, 11, and the side plate supports 21b of the lower ladder-shaped side plates 20B are fixed to the main support columns 11 with connecting bolts 24. At this time, the lowest step 23b of the lower ladder-shaped side plate 20B is on the bottom 11b of the main support column 11, and the lowest step 23b of the lower ladder-shaped side plate 20B and the bottom 11b of the main support column 11 are fixed with connecting bolts 32.

[0125] Next, a rear brace 30 is installed behind a pair of adjacent main support columns 11, 11, and this rear brace 30 is fixed to the rear surface of the main support columns 11, 11 with connecting bolts 31. In this way, each main support column 11, 11 can be firmly fixed by the rear brace 30.

[0126] Subsequently, the upper flat portion 41 of each upper ladder-shaped side plate 20A and the lower flat portion 42a of the lower ladder-shaped side plate 20B are connected with connecting bolts 40. This allows the upper ladder-shaped side plate 20A and the lower ladder-shaped side plate 20B to be firmly fixed together.

[0127] Next, the inner pipe 12, which is located at the top of the main support column 11, is extended upward, and the contact fitting 13 of the inner pipe 12 is brought into contact with the ceiling C. At this position, the inner pipe 12 is fixed to the main support column 11 by the fixing fitting 14. This allows the main support column 11 to be sandwiched between the bottom surface F and the ceiling C, and the main support column 11 can be firmly fixed in place.

[0128] Subsequently, a shelf board 25 is placed between the desired steps 23a and 23b of the ladder-shaped side plates 20 of an adjacent pair of main support columns 11, 11. In this case, the shelf board 25 is hooked onto the steps 23a and 23b via hooks 25a.

[0129] In this way, the wall-mounted storage device 10 is obtained. Of this wall-mounted storage device 10, the ladder-shaped side plates 20 and the shelves 25 are made entirely or partially from stainless steel, steel, or aluminum. As mentioned above, the main support columns 11, 11, 11 are also made from stainless steel, steel, or aluminum.

[0130] As described above, according to this embodiment, the ladder-shaped side plate 20, which consists of an upper ladder-shaped side plate 20A and a lower ladder-shaped side plate 20B, is mounted on the bottom 11b of the L-shaped main support column 11. Therefore, the ladder-shaped side plate 20 can be stably held by the main support column 11, and the ladder-shaped side plate 20 will not fall or detach from the main support column 11. Furthermore, by fixing the ladder-shaped side plate 20 to the side 11a and bottom 11b of the main support column 11, the ladder-shaped side plate 20 can be firmly fixed to the main support column 11. As a result, even if the stylish ladder-shaped side plate 20 is made of thin material which has high design quality but low strength, the ladder-shaped side plate 20 will not deform even if reinforcing structures such as truss structures or bracing structures are not provided at the top or bottom of the ladder-shaped side plate 20. Therefore, compared to cases where reinforcing structures such as truss structures or bracing structures are provided at the top or bottom of the ladder-shaped side plate 20, it is possible to eliminate dead space caused by the provision of reinforcing structures, and to effectively utilize the top and bottom of the ladder-shaped side plate 20.

[0131] Furthermore, the inner tube 12 provided on the main support column 11 is extended upwards, and the contact fitting 13 is brought into contact with the ceiling C, and at this position the inner tube 12 is fixed to the main support column 11 by the fixing fitting 14. In this way, the main support column 11 can be sandwiched between the bottom surface F and the ceiling C, and the main support column 11 can be firmly fixed along the wall surface W.

[0132] Furthermore, the ladder-shaped side plate 20 has an upper ladder-shaped side plate 20A and a lower ladder-shaped side plate 20B that are separable from each other, and the upper ladder-shaped side plate 20A and the lower ladder-shaped side plate 20B are connected by tightening connecting bolts 40 between the upper flat portion 41 and the lower flat portion 42a. The lower ladder-shaped side plate 20B is also removable from the main support column 11. Therefore, only the lower ladder-shaped side plate 20B can be removed from the main support column 11.

[0133] Furthermore, the horizontal connecting rod 42 of the lower ladder-shaped side plate 20B does not extend between the pair of side plate supports 21a and 22a, as does the lowest step portion 23a of the upper ladder-shaped side plate 20A, but terminates at the upper flat portion 41 of the upper ladder-shaped side plate 20A. Therefore, the lowest step portion 23a of the upper ladder-shaped side plate 20A extends horizontally from the side plate support 22a to form the upper flat portion 41 and then extends further to the side plate support 21a. Consequently, compared to the case where the lowest step portion 23a of the upper ladder-shaped side plate 20A extends overlapping with the step portion 23b of the lower ladder-shaped side plate 20B, the lowest step portion 23a of the upper ladder-shaped side plate 20A extends independently, and the design is not diminished.

[0134] <Third Embodiment> Next, a third embodiment of this disclosure will be described with reference to Figure 16.

[0135] In the third embodiment shown in Figure 16, for example, two tensioning posts 1 are installed between the chest of drawers 80, which is placed on the floor surface F, and the ceiling C. These tensioning posts 1 prevent the chest of drawers 80 from tipping over even if the building shakes due to an earthquake or the like. Preferably, each tensioning post 1 is installed on both sides of the top surface of the chest of drawers 80, closer to the wall surface W. By installing the tensioning posts 1 on both sides of the top surface of the chest of drawers 80, closer to the wall surface W, the tensioning posts 1 and the abutment 13 are located towards the back of the chest of drawers 80. Therefore, when the tensioning posts 1 are placed on tall furniture such as the chest of drawers 80, the tensioning posts 1 and the abutment 13 are not easily visible from the perspective of a resident in the living space, so the appearance of the furniture is not spoiled.

[0136] In Figure 16, the support column 1 has a cylindrical main column 81 and a sliding pipe 82 that is slidably installed inside the main column 81. A fixing device 83 is attached to the main column 81 to fix the sliding pipe 82 in a predetermined position relative to the main column 81.

[0137] Furthermore, a contact device 13 is provided at the top of the sliding pipe 82 of each support column 1 to contact the ceiling C, and an additional contact device 63 is provided at the bottom of the main support column 81 to contact the top surface of the chest of drawers 80.

[0138] In this embodiment, the contact fitting 13 and the additional contact fitting 63 both have the same structure as the contact fitting 13 shown in Figures 11A to 12D, and the additional contact fitting 63 shown in Figures 13A and 13B.

[0139] In other words, the contact device 13 shown in Figure 16 has a contact device body 51 and a contact surface 53 provided on the contact device body 51 that contacts the ceiling C (see Figures 11A to 12E).

[0140] In this embodiment, both the contact body 51 and the contact surface 53 have an L-shape when viewed from above. The contact body 51 of the contact 13 is made of polypropylene (PP) and is attached to the sliding pipe 12 via mounting screws 55. Furthermore, the contact surface 53 is made of silicone.

[0141] Both the silicone contact surface 53 and the polypropylene (PP) contact body 51 are L-shaped in plan view, but the contact surface 53 is slightly smaller than the contact body 51, and in the plan view of the contact device, the contact body 51 is slightly visible as a band, for example, 1.5 to 2 mm wide, around the outer circumference of the contact surface 53 (see Figures 11A and 11B).

[0142] The contact surface 53 of the contact fitting 13 has a square portion 53a and a pair of extension portions 53b1 and 53b2 extending from two adjacent sides of the square portion 53a in directions 90° apart from each other, so that the contact surface 53 as a whole is L-shaped. In this case, the square portion 53a of the contact fitting 13 is square-shaped, and each extension portion 53b1 and 53b2 is rectangular-shaped. However, each extension portion 53b1 and 53b2 may also be square-shaped.

[0143] Furthermore, the mounting screw 55 provided on the contact fitting 13 is positioned at the center of the square portion 53a of the contact surface 53, and as a result, the sliding tube 12 connected to the mounting screw 55 is also positioned at the center of the square portion 53a of the contact surface 53 (see Figure 12E). In this case, the mounting screw 55 does not necessarily have to be positioned at the center of the square portion 53a; for example, the mounting screw 55 may be provided on the diagonal line L3 connecting the outer corner 53a1 and the inner corner 53a2 of the square portion 53a, or at any position within the square portion 53a. By providing the mounting screw 55 at the center of the square portion 53a, on the diagonal line L3 connecting the outer corner 53a1 and the inner corner 53a2 of the square portion 53a, or at any position within the square portion 53a, the force applied to the main support column 11 can be reliably transmitted to the contact fitting 13.

[0144] According to this embodiment, the contact surface 53 of the contact fitting 13 has a square portion 53a and a pair of extension portions 53b1 and 53b2, forming an L-shape in plan view. The mounting screw 55 and the sliding tube 12 are positioned at the center of the square portion 53a. As a result, the external force applied to the bracing column 1 is transmitted to the ceiling C, and the bracing column 1 can be reliably supported by the contact fitting 13.

[0145] The additional contact device 63 also has an additional contact device body 71 and an additional contact surface 73 provided on the additional contact device body 71 that contacts the top surface of the chest of drawers 80 (see Figures 13A and 13B).

[0146] In this embodiment, both the additional contact body 71 and the additional contact surface 73 have an L-shape in plan view. The additional contact body 71 of the additional contact 63 is made of polypropylene (PP) and is attached to the main support column 81 via mounting screws 75. Furthermore, the additional contact surface 73 is made of silicone.

[0147] As shown in Figures 13A and 13B, the additional contact surface 73 of the additional contact device 63 has an additional square portion 73a and a pair of additional extension portions 73b1 and 73b2 extending from two adjacent sides of the additional square portion 73a in directions 90° apart from each other, so that the additional contact surface 73 as a whole is L-shaped. In this case, the additional square portion 73a of the additional contact device 63 is square-shaped, and each additional extension portion 73b1 and 73b2 is rectangular-shaped. However, each additional extension portion 73b1 and 73b2 may also be square-shaped.

[0148] Furthermore, the mounting screw 75 provided on the additional contact device 63 is positioned at the center of the additional square portion 73a of the additional contact surface 73, and as a result, the main support column 81 connected to the mounting screw 75 is also positioned at the center of the additional square portion 73a of the additional contact surface 73 (see Figure 13A). Note that each additional extension portion 73b1, 73b2 may have a square shape. In this case, the mounting screw 75 does not necessarily have to be positioned at the center of the additional square portion 73a; for example, the mounting screw 75 may be provided on the diagonal line L4 connecting the outer corner 73a1 and the inner corner 73a2 of the additional square portion 73a, or at any position within the additional square portion 73a. By providing the mounting screw 75 at the center of the additional square portion 73a, on the diagonal line L4 connecting the outer corner 73a1 and the inner corner 73a2 of the additional square portion 73a, or at any position within the square portion 73a, the force applied to the main support column 11 can be reliably transmitted to the additional contact device 63.

[0149] According to this embodiment, the additional contact surface 73 of the additional contact device 63 has an additional square portion 73a and a pair of additional extension portions 73b1 and 73b2, forming an L-shape in plan view. The mounting screw 75 and the main support column 81 are positioned at the center of this additional square portion 73a. As a result, the external force applied to the tension support column 1 is transmitted to the top surface of the chest of drawers 80, and the tension support column 1 can be reliably supported by the additional contact device 63.

[0150] Next, with reference to Figure 16, the effects of the contact fittings 13 attached to the upper part of each sliding pipe 82 and the additional contact fittings 63 attached to the lower part of each main support column 81 will be described below.

[0151] As shown in Figure 16, each contact fitting 13 attached to the upper part of each sliding pipe 82 has a contact fitting body 51 and a contact surface 53, and the contact fitting 13 is arranged so that a square portion 53a and one extended portion 53b1 extend in a direction L1 perpendicular to the wall surface W.

[0152] The square portion 53a and the other extension portion 53b2 of the connector 13 extend parallel to the wall surface W.

[0153] Generally, when a chest of drawers 80 is placed parallel to a wall W, if the building shakes along the wall W due to an earthquake or the like, an external force L in a direction parallel to the wall W is applied to the chest of drawers 80. As described above, since the contact device 13 has a square portion 53a and the other extended portion 53b2 that extends parallel to the wall W, the contact surface 53 extends for a relatively long distance in the direction L parallel to the wall W. As a result, even if an external force L in the direction parallel to the wall W acts on the chest of drawers 80, the square portion 53a that extends in the direction L parallel to the wall W and the other extended portion 53b2 of the contact surface 53 can effectively transmit this external force to the ceiling C.

[0154] Furthermore, even when an external force is applied to the chest of drawers 80 along a direction L1 perpendicular to the wall surface W, the square portion 53a extending along the direction L1 perpendicular to the wall surface W and the other extension portion 53b1 of the contact surface 53 can effectively transmit this external force to the ceiling C. In other words, when an external force is applied to the chest of drawers 80 along a direction L1 perpendicular to the wall surface W, the square portion 53a extending along the direction L1 perpendicular to the wall surface W and the other extension portion 53b1 reliably engage with the ceiling C.

[0155] Therefore, when an external force is applied to the chest of drawers 80 along the direction L1 perpendicular to the wall surface W, this external force can be reliably transmitted to the ceiling C, and the contact device 13 will not come off the ceiling C.

[0156] Similarly, the additional contact device 63 has an additional contact device body 71 and an additional contact surface 73, and the additional contact device 63 is arranged such that an additional square portion 73a and one additional extension portion 73b1 extend in a direction perpendicular to the wall surface W.

[0157] The additional square portion 73a and the other additional extension portion 73b2 of the additional contact fitting 63 extend parallel to the wall surface W.

[0158] Generally, when a chest of drawers 80 is positioned to extend parallel to a wall W, an external force L parallel to the wall W is applied to the chest of drawers 80 when the building shakes along the wall W due to an earthquake or the like. As described above, the additional contact piece 63 has an additional square portion 73a and the other additional extension portion 73b2 that extend parallel to the wall W, so the additional contact surface 73 extends for a relatively long distance along the direction L parallel to the wall W. As a result, even when an external force L parallel to the wall W acts on the chest of drawers 80, the additional square portion 73a that extends in the direction L parallel to the wall W and the other additional extension portion 73b2 of the additional contact surface 73 can effectively transmit this external force to the top surface of the chest of drawers 80.

[0159] Furthermore, even when an external force is applied to the chest of drawers 80 along a direction L1 perpendicular to the wall surface W, the additional square portion 73a extending along the direction L1 perpendicular to the wall surface W and the additional extension portion 73b1 of the additional contact surface 73 can effectively transmit this external force to the top surface of the chest of drawers 80. In other words, when an external force is applied to the chest of drawers 80 along a direction L1 perpendicular to the wall surface W, the additional square portion 73a extending along the direction L1 perpendicular to the wall surface W and the additional extension portion 73b1 reliably engage with the top surface of the chest of drawers 80.

[0160] Therefore, when an external force is applied to the chest of drawers 80 along the direction L1 perpendicular to the wall surface W, this external force can be reliably transmitted to the top surface of the chest of drawers 80, and the additional contact device 63 will not detach from the top surface of the chest of drawers 80. [Examples]

[0161] Next, a specific embodiment of this model will be described. In this embodiment, we prepared a wall storage device 10 having an L-shaped contact surface according to this embodiment as shown in Figure 14A, and a comparative example wall storage device 10 having an elongated (strip-shaped) contact surface extending along the wall surface W as shown in Figure 14B. We then demonstrate the behavior of each of these wall storage devices when a load is applied. <Example 1 and Comparative Example 1> In Example 1, a wall-mounted storage device 10 with a total height of 2250 mm, as shown in Figure 14A, was prepared. A load was applied to this wall-mounted storage device 10 at a load height of 1660 mm along a direction L1 perpendicular to the wall surface W, and this load was gradually increased. In Example 1, when a load of 150N was applied, displacement occurred in the lower part of the wall-mounted storage device 10. In Comparative Example 1, a wall-mounted storage device 10 with a total height of 2250 mm, as shown in Figure 14B, was prepared. A load was applied to this wall-mounted storage device 10 at a load height of 1660 mm along a direction L1 perpendicular to the wall surface W, and this load was gradually increased. In Comparative Example 1, when a load of 140N was applied, displacement occurred in the lower part of the wall-mounted storage device 10. From the above, it was found that in Example 1, when a load is applied to the wall storage device 10 along the direction L1 perpendicular to the wall surface W, its behavior is more stable compared to Comparative Example 1.

[0162] <Example 2 and Comparative Example 2> In Example 2, a wall-mounted storage device 10 with a total height of 2250 mm, as shown in Figure 14A, was prepared. A load was applied to this wall-mounted storage device 10 at a load height of 1660 mm along a direction L1 perpendicular to the wall surface W, and this load was gradually increased. The wall-mounted storage device 10 also had five shelves 25, and a 10 kg weight was placed on each shelf 25, for a total weight of 50 kg. In Example 2, when a load of 270N was applied, displacement occurred in the lower part of the wall-mounted storage device 10. In Comparative Example 2, a wall-mounted storage device 10 with a total height of 2250 mm, as shown in Figure 14B, was prepared. A load was applied to this wall-mounted storage device 10 at a load height of 1660 mm along a direction L1 perpendicular to the wall surface W, and this load was gradually increased. The wall-mounted storage device 10 also had five shelves 25, and a 10 kg weight was placed on each shelf 25, for a total weight of 50 kg. In Comparative Example 2, when a load of 245N was applied, displacement occurred in the lower part of the wall-mounted storage device 10. From the above, it was found that in Example 2, when a load is applied to the wall storage device 10 along the direction L1 perpendicular to the wall surface W, its behavior is more stable compared to Comparative Example 2.

[0163] <Example 3 and Comparative Example 3> In Example 3, a wall-mounted storage device 10 with a total height of 2250 mm, as shown in Figure 14A, was prepared. A load was applied to this wall-mounted storage device 10 at a load height of 1660 mm along a direction L1 perpendicular to the wall surface W, and this load was gradually increased. The wall-mounted storage device 10 also had five shelves 25, and a 20 kg weight was placed on each shelf 25, for a total weight of 100 kg. In Example 3, when a load of 380N was applied, displacement occurred in the upper part of the wall-mounted storage device 10. In Comparative Example 3, a wall-mounted storage device 10 with a total height of 2250 mm, as shown in Figure 14B, was prepared. A load was applied to this wall-mounted storage device 10 at a load height of 1660 mm along a direction L1 perpendicular to the wall surface W, and this load was gradually increased. The wall-mounted storage device 10 also had five shelves 25, and a 20 kg weight was placed on each shelf 25, for a total weight of 100 kg. In Comparative Example 3, when a load of 320N was applied, displacement occurred in the upper part of the wall-mounted storage device 10. From the above, it was found that in Example 3, when a load is applied to the wall storage device 10 along the direction L1 perpendicular to the wall surface W, its behavior is more stable compared to Comparative Example 3.

[0164] <Example 4 and Comparative Example 4> In Example 4, a wall-mounted storage device 10 with a total height of 2250 mm, as shown in Figure 14A, was prepared. A load was applied to this wall-mounted storage device 10 at a load height of 1660 mm along a direction L parallel to the wall surface W, and this load was gradually increased. In Example 4, when a load of 100N was applied, displacement occurred in the lower part of the wall-mounted storage device 10. In Comparative Example 4, a wall-mounted storage device 10 with a total height of 2250 mm, as shown in Figure 14B, was prepared. A load was applied to this wall-mounted storage device 10 at a load height of 1660 mm along a direction L parallel to the wall surface W, and this load was gradually increased. In Comparative Example 4, when a load of 100N was applied, displacement occurred in the lower part of the wall-mounted storage device 10. From the above, it was found that in Example 4, when a load is applied to the wall storage device 10 along the direction L parallel to the wall surface W, it exhibits the same behavior as in Comparative Example 4.
