The hanging tool (1) of Patent Document 1 is equipped with a magnet (3) on the back side of a base (2) on which a hanging hook (4) is provided, and a non-slip sheet (5) is adhered thereto. The back surface is magnetically attached to the wall surface (W) by the magnetic force of the magnet (3).

  The suspension bracket (8) of Patent Document 2 has L-shaped iron plates (2) and (3) arranged on both sides of the magnet (1), and bridge portions (1) that integrally connect the iron plates (2) and (3) ( 5) is a structural part for suspension. For example, as shown in FIG. 3, a plurality of suspension fittings (8) are magnetically attached to the ceiling wall, and the pipes and ducts (12) are suspended and supported with sufficient productivity and workability and sufficient support strength. Is possible.

  Since it is a convenient magnetic support as described above, it is desired to expand its range of use. A typical example is a magnetic support that can support a heavy object without peeling off. For example, a wall-mounted magnetic hanger that can hang heavy clothing such as a wet coat or a set of ski wear, a storage shelf or a storage container (magnetic-attached furniture) that can be used by being magnetically attached to the wall. If these can be realized, for example, in temporary opening of a part of the venue or limited-time sales operations, supported objects such as hangers, display racks, and showcases can be easily installed on partition walls and doors, and withdrawn. It will be easy to do. In other words, it is possible to support a product having a considerable weight while maintaining the advantage of being convenient and easy to use, and the range of use as a magnetic support can be expanded.

  For this purpose, it is quick to install a magnet having a stronger magnetizing force. For example, in the case where the number of magnets is doubled or tripled and the magnetic force is doubled or tripled, the magnet cost is reduced. Is doubled and tripled, which is not a good idea. The same applies to the means for increasing the size of the magnet. Moreover, although the means using a strong magnet (example: samarium cobalt magnet) and a super-strong magnet (example: neodymium magnet) are also considered, cost will increase drastically by adoption of these, and it is not realistic. Therefore, further devices have been required to realize a magnetic support that can support heavier than conventional ones.

Means 1, a twisted portion 2 that abuts against the wall surface W at a position below the magnetic force means 1, and a support portion 3 that spans between the magnet 1 and the twisted portion 2 to support the supported object. Configured. FIG. 1 shows a use state in which the magnet is magnetically attached to a wall surface W such as a partition wall.

  As shown in FIGS. 1, 2, and 3 (a), the magnetic force means 1 includes large and small magnet portions 1 </ b> A and 1 </ b> B that are formed by alternately arranging rectangular permanent magnets 4 and iron metal plates 5. It is configured to be attached by means such as sticking to the back surface 6b of the substrate 6. A clear gap is formed between the large magnet portion 1A and the small magnet portion 1B, and the support portion 3 is screwed on the substrate 6 in the gap portion with the base end portion 3a positioned on the surface 6a. 7 stops. In addition, although illustration is abbreviate | omitted, the guard cloth for protecting the wall surface W without being damaged is attached to the magnetic attachment side surface of the some metal plate 5 in the large and small magnet parts 1A and 1B.

  As shown in FIGS. 1 and 2, the support unit 3 is provided with the magnetic force means 1 at the base end in the use state where the magnetic support A is magnetically attached to the vertical wall surface W (an example of the horizontal direction). 3A, the lower horizontal beam member 3B protruding in the horizontal direction (an example of the horizontal direction) with the bent portion 2 at the base end, the distal end of the upper horizontal beam member 3A and the distal end of the lower horizontal beam member 3B And a vertical member 3 </ b> C that connects the parts. Each of the members 3A, 3B, 3C is formed of a metal bar (a metal square-shaped material) having a solid square cross section. The support part 3 is formed in a shape that is U-shaped so that the side view shape is opened to the wall surface W side, and thereby the upper base end part 3a and the curled part 2 that are places where the magnetic force means 1 is supported. The detour shape is set so that the lower base end portion 3b, which is the supporting portion, is not continuous vertically.

  As shown in FIGS. 1 and 3 (b), the bent portion 2 is a lower horizontal beam member using a substantially cylindrical rubber cushion 8 and a screw 10 through which a recess 8a and a through hole 8b are formed. It is comprised by attaching to the base end surface 9 of 3B. In other words, the bent portion 2 is made of an elastic material (rubber) capable of exhibiting an anti-slip action by contact with the wall surface W.

  The upper part of the magnetic support A having such a structure is magnetically attached to the wall surface W by the permanent magnet 4, and the lower part clearly separated downward due to the detour shape of the support part 3 is attached to the wall surface W via the rubber cushion 8. It is in contact. The advantage is that the upper base end 3a and the lower base end 3b are simply structured so as not to be continuous vertically, but the load acting on the support part 3 without falling off the wall surface W and falling. It is possible to increase drastically. Next, the theory will be explained.

  First, FIG. 8A shows an example of a conventional general magnetic attachment support A, which has a structure in which the support portion 3 protrudes from the upper and lower centers of the magnetic force means 1. The amount of protrusion in the horizontal direction from the wall surface W of the support portion 3 is L, half of the upper and lower magnetic attachment lengths of the magnetic means 1 on the wall surface W is D, and the magnetic attachment force by the magnetic means 1 is F. From the balance of the moment with the peeling fulcrum P from the wall W, the maximum load M1 acting on the tip of the support portion 3 is M1 = F × D / L (1).

  Next, FIG. 8 (b) shows an example of a magnetic support A according to the present invention. It has the support part 3 which is equivalent to what is shown in FIG. 1 etc., and exhibits a U-shape in a side view, and the protrusion amount from the wall surface W of the magnetic force means 1 and the support part 3 is shown in FIG. The distance between the upper and lower centers of the magnetic force means 1 and the contact point P of the bent portion 2 is 3D. In this case, the maximum load M2 acting on the tip of the support portion 3 is M2 = F × 3D / L (2), which is three times M1 according to the above equation (1). That is, the load resistance of the supported object acting on the support part 3 such as a hanger or a shelf is increased three times as compared with the conventional case.

  In addition, since the support portion 3 having a detour shape in a side view has a structure in which the upper and lower horizontal beam members 3A and 3B are connected to each other at the distal end portion on which the load acts, Compared with a magnetic support having a structure in which the upper and lower base ends 3a and 3b are continuous, such as a reverse U shape, the rigidity and strength as the support are clearly improved. 3 can be reduced in weight and cost while having sufficient strength and rigidity. Since the support portion 3 is formed in a U shape in a side view, it is easy to suspend or support the supported object on the upper horizontal beam member 3A or the lower horizontal beam member 3B, and the presence of the vertical member 3C. It has a rigid frame structure with sufficient strength and rigidity.

  By the way, by operating the screw 7, the large magnet portion 1A and the small magnet portion 1B constitute the magnetic force means 1 and the support portion 3 in a state that is upside down as shown in FIG. It can be used as a magnetic attachment support A in which the vertical distance between 1 and the twisted portion 2 is widened to further improve the peeling resistance. That is, it is possible to use the upper and lower directions of the magnetic force means 1 corresponding to two types depending on the conditions of the magnetic attachment location such as the wall surface and various conditions such as the size and weight of the supported object.
