Description

  The present invention relates to a magnetic support that is suitably used for wall surfaces that can adsorb magnetic force such as side walls, partition walls, and ceiling walls of buildings, and more specifically, a magnet for magnetically attaching to a wall surface, and a supported object. The present invention relates to a magnetic support having a support portion for supporting the magnetic field.

  As this type of magnetic support, a hanging tool disclosed in Patent Document 1 and a hanging metal fitting disclosed in Patent Document 2 are known. 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.

  These magnetic support tools (generic names for hanging tools, hanging brackets, etc.) have the advantage of being able to easily support a supported object with a considerable weight, such as clothes, bags, watches, etc., due to its strong magnetic force. By the way, because of its strong magnetic force, it is unexpectedly difficult to remove it once it is magnetically attached to the wall surface. This difficulty in removing the magnetic support is as described in paragraph No. 0004 of Patent Document 3.

  Therefore, the magnetic suspension disclosed in Patent Document 3 has been devised so that it can be easily removed. That is, the suspension mounting body (2) including the suspension (3) is supported to be swingable with respect to the magnet mounting body (1) including the magnet (4). In other words, this principle functions with the support shaft (12) as a fulcrum by pulling and lifting the suspender (3) toward the front, and the magnet mounting body (1) is pulled away from the wall surface at the end by the amplified force. It can be done.

  However, in order to improve the convenience of removal, there is a cost of separately providing a hanging tool mounting body (2) and a magnet mounting body (1), and pivoting both of them together so that they can swing. The structure is complicated and the structure is complicated. In addition, with magnetic attachment supports that use heavy magnets to withstand heavy objects, each component and pivotal structure must be further enhanced in strength and rigidity, which is not very good in terms of cost performance, and there is room for improvement. There seems to be.

  The object of the present invention is to develop and provide a magnetic support that is improved so that the structure can be easily removed and the cost can be reduced without much cost by further structural improvements. is there.

The invention according to claim 1 is a magnetic attachment support device comprising a magnet 3 to be magnetically attached to the wall surface W and a support portion 2 to support the supported object M.
In the state of use in which the frame 3 is provided that holds the magnet 3 and includes the support portion 2 and is magnetically attached to the wall surface W by the magnet 3, the lateral side of the magnet 3 in the frame 1. A gap 13 that allows insertion of the finger y is formed between the portion 11 and the wall surface W,
The portion 11 located on the lateral side of the magnet 3 protrudes more clearly laterally than the surrounding portion 1B that houses the magnet 3 in the frame 1.
By pulling back the portion 11 located on the lateral side by the finger y inserted into the gap portion 13, the end opposite to the finger y existence side in the end surface 10 a of the yoke 10 that houses the magnet 3 is used as a fulcrum P. It is configured to swing and move.

  According to a second aspect of the present invention, in the magnetic support according to the first aspect, the magnet 3 is configured to have a rectangular shape as viewed in the direction of magnetic attachment to the wall surface W, and the gap 13 is the It is set in the state located in the horizontal direction which cross | intersects the longitudinal direction of the said magnet 3 in the magnetizing direction view.

  According to a third aspect of the present invention, in the magnetic support according to the first or second aspect, the support portion 2 erected from the frame body 1 a rod-like body 6 capable of supporting the object M to be supported. Therefore, it is configured to have a hole 2 </ b> A formed in the frame body 1.

  According to the first aspect of the present invention, although described in detail in the section of the embodiment, the magnetic support is separated by swinging movement about the one end of the magnetic adhesion portion to the wall surface, that is, on this principle. Thus, the frame can be detached from the wall surface and removed. That is, it is possible to remove the magnetic support in a light manner without forcibly moving the magnetic support with a relatively light force with fingers. As a result, we have developed and provided a magnetic support that is improved so that it can be easily removed and has a simple structure and does not require a significant increase in cost.

  According to the second aspect of the present invention, which will be described in detail in the section of the embodiment, the longitudinal direction of the magnet in the magnetizing direction is larger than the configuration in which the gap is in the longitudinal direction of the magnet in the magnetizing direction. In the case of the configuration in which the gap is positioned in the intersecting lateral direction, the pulling force from the wall surface can be reduced. Therefore, by setting the location of the gap in consideration of the shape of the magnet, the frame body can be more easily separated from the wall surface, and the advantage of the effect of the invention of claim 1 can be obtained. .

  According to the invention of claim 3, the structure is simple and additional parts such as a hanger or hook can be hooked on the hole formed in the frame body, or a rod-like hook or metal fitting can be screwed using the hole. It is possible to provide a magnetic support that has an economical structure and is easy to use.

  Embodiments of a magnetic support according to the present invention will be described below with reference to the drawings. 1 to 4 show the magnetic support of the first embodiment, and FIGS. 5 and 6 show the magnetic support of the second embodiment. FIG. 8 shows a magnetic attachment support of another embodiment.

[Example 1]
As shown in FIGS. 1 to 3, the magnetic support A according to the first embodiment for hanging is equipped with an acrylic frame 1, a support 2 provided on the frame 1, and the frame 1. The plurality of magnets 3 are configured. That is, the magnet 3 that is magnetically attached to the wall surface W, the support 2 that supports the supported object M such as a bag, and the frame 1 that holds the magnet 3 and includes the support 2. A magnetic attachment support A is provided.

  The frame body 1 has a flat plate portion 1A that forms a rectangular parallelepiped when viewed from the front, and a surrounding portion 1B that is formed on the back side of the flat plate portion 1A so as to accommodate and deploy the magnet 3, and closes upward at the center of the flat plate portion 1A. A single hole 2 </ b> A penetrating back and forth is formed in this place, and the support portion 2 is configured by this hole 2. In the magnetic support A of Example 1, the metal rod 6 is screwed by using the screw 4 and the pair of washers 5 and 5 that are passed through the hole 2A from the back side to the front side of the flat plate portion 1A. A supported object M such as a plastic bag, a bag, a hanger or the like can be suspended from a metal rod 6 erected from the surface 1a of the part 1A. Note that a rubber ring 7 is attached to the tip of the metal rod 6 to prevent it from coming off. That is, the support portion 2 is configured to have a hole 2A formed in the frame body 1 in order to erect the rod-shaped body (metal bar) 6 that can support the suspended object M from the frame body 1. Yes.

  The flat plate portion 1A is a rectangular plate having a predetermined thickness, and the surrounding portion 1B is a portion having a square space portion surrounded by a pair of left and right vertical strips 8 and 8 and a pair of upper and lower horizontal strips 9 and 9. . In the surrounding portion 1B, six flat rectangular magnets 3 having a slightly oblong shape and a small thickness are arranged in a line in the vertical direction. The vertical width of the flat plate portion 1A is the same size as the full width of the horizontal strips 9, 9, but the horizontal width is clearly wider than the full width of the vertical strips 8, 8, and the protruding plate portions (" An example) 11 is formed. As shown in FIG. 3B, the decorative portion 19 may be formed on the surface of the frame 1 by attaching decorative paper or the like.

  Each magnet 3 is accommodated in a yoke 10 made of a metal plate having a U-shape, and a pair of long end surfaces 10a, 10a of each yoke 10 protrude slightly rearward from the magnet 3, and a total of 12 The end surface 10a of the location is a portion that is magnetically attached to the wall surface W. Each of the strips 8 and 9 has the same height and is lower than the end face 10a of each yoke 10. A gap is provided between the upper and lower magnets 3 and 3 and a hole 2 is formed in the flat plate portion 1A in the gap portion. Therefore, the screw 4 is tightened or loosened by a screwdriver (screwdriver) using the gap portion. Moreover, in order to protect the wall surface W, each magnet 3 (and each end surface 10a) is covered with the protective cloth 12 equipped by adhesion | attachment etc.

  When the magnetic support A is magnetically attached to the wall surface W, there is a gap between the left and right overhanging plate portions 11 and the wall surface W so that the finger y can be inserted. It has become. Specifically, a gap portion 13 that allows insertion of the finger y is formed between a portion of the frame body 1 that is located laterally of the magnet 3, that is, between the overhang plate portion 11 and the wall surface W. ing. That is, the magnet 3 as a whole is configured to have a rectangular shape when viewed in the direction of magnetic attachment to the wall surface W (in the direction of arrow A), and the gap 13 is in the longitudinal direction of the magnet (in the direction of arrow B) in plan view. It is set in a state of being located in the intersecting lateral direction (arrow C direction). Therefore, in order to remove the vertically long magnetic support A according to the first embodiment from the wall surface W, the following operation is performed.

  First, as shown in FIG. 4 (a), a finger y is approached from the lateral side of the magnetic support A that is magnetically attached to the wall surface W, and the fingertip is slid into the gap 13 so as to extend the plate. 11 on the back side. Next, as shown in FIG. 4B, when a force is applied so that the finger y is pulled back to pull the overhanging plate portion 11 vertically away from the wall surface W, it is opposite to the finger y existing side on the end surface 10a of the yoke 10. The frame body 1 can swing and move away with the side end as a fulcrum P (vertical vertical axis).

In this case, the left-right width of the end face 10a is 2d, the distance from one end of the end face 10a to the end of the opposite frame 1 is D, and the fingers y required to pull the magnetic support A from the wall W The force F is expressed by d × f = D × F, where f is the magnetic adhesion force by the magnet 3 (see FIG. 4A).
(1) ... F = d × f / D
It becomes. That is, the “lever principle” can be used by inserting the finger y into the gap portion 13 and can be separated by a swinging movement around the fulcrum P. Without pulling the frustration to peel off, without causing the conventional inconvenience that the magnetic adhesion support or fingers hit other objects by the reaction, or drag the magnetic support to damage the wall, It can be easily and easily removed from the wall surface W with a relatively light force.

  As a comparative reference, as shown in FIG. 8, the magnetized support At is formed with a protruding plate portion (an example of a “portion located on the lateral side of the magnet”) 11 on the top and bottom of the magnet 3. Consider the case of removal. In this case, for simplicity, it is assumed that the magnetic force ft by the plurality of magnets 3 is in the center of the vertical width (2 × dt) of the magnets 3, and the overhang amount (length) ht of the upper and lower overhang plate portions 11 is It is assumed that the extension amount h of the magnetic adhesion support A according to the first embodiment is the same (h = ht).

For example, when pulling away using the lower overhanging plate portion 11, the force Ft required for the finger y is similarly
(2) ... Ft = dt × ft / Dt
It becomes. Here, when d = 22.5, D = 73, dt = 100, and Dt = 228 (unit: mm) are substituted as dimension examples of the magnetic support A and At, F≈0.308f, Ft≈0. 439 ft. Since f = ft, F = 0.702 Ft. In other words, the force (separation force) required for the finger y is about 70% in the case of the landscape orientation.

[Example 2]
As shown in FIGS. 5 and 6, the magnetic attachment support A according to Example 2 is obtained by changing the usage of the support portion 2. That is, a magnetic attachment support A of a magazine rack specification that can hold and hold a book, a magazine, a monthly magazine, etc., and is a rod-like body that is screwed to the support portion 2 with the same structure as in the first embodiment. 6, a magnetic support A having a base 16 having a base plate 14 screwed to the tip of the rod-like body 6 and a receiving plate 15 pivotally supported by the base plate 14. The other parts are the same as the magnetic support A in Example 1.

  The base plate 14 made of a plate material such as a stainless steel plate has left and right walls 14a fixed to the rod-like body 6 with screws 17, a pair of left and right side walls 14b and 14b formed to bend from the left and right ends of the left and right walls, and each side wall. It is a substantially U-shaped member provided with a pair of left and right hooking walls 14c, 14c formed by bending from the base end of 14b. The receiving plate 15 made of a plate material such as a stainless steel plate is provided with a bottom plate 15a, a backrest plate 15b, and a pair of left and right support plates 15c and 15c, and a left and right axial center on the base plate 14 using a pair of left and right butterfly bolts 18 and 18. It is pivotally connected so that the angle can be changed around X.

  A nut 19 and an insertion hole (not shown and not shown) for screwing the butterfly bolt 18 are provided on the distal end side of each side wall 14b, and the backrest plate 15b has a desired inclination angle θ with respect to the wall surface W. In this state, the left and right butterfly bolts 18 are tightened, and the receiving plate 15 is screwed and locked to the base plate 14 in a posture determination state. Thereby, as shown in FIG. 5, the convenient magnetic support A which can place the magazine m etc. on the stand 16 inclining is constructed.

[Another Example]
In order to facilitate insertion of the finger y into the gap 13, as shown on the right side of FIG. 7, the overhanging plate 11 is inclined so that an angle α that approaches the front as the back surface 11 a goes to the lateral end is attached. It may be a magnetic support A having a tapered shape. Further, for the same purpose, as shown on the left side of FIG. 7, the magnetized support having a structure in which the overhanging plate portion 11 is bent so as to approach the wall surface W from the base portion thereof to have an opening angle β. Tool A may be used.

  Although not shown in the drawings, the support portion 2 is not limited to the hole 2A formed in the flat plate portion 1A, but includes a hook portion integrally formed with the frame body 1 and an open box (bag) -like storage portion. Can be changed. 5 and 6 may be defined as the support portion 2 as a whole when the pedestal 17 shown in FIGS.
