Description

  The present invention relates to a magnet holder, and more specifically, a magnet that can greatly reduce the burden of removal even when a magnet that exhibits strong adhesion to a partition or a door or other adherent surface is used. Regarding the holder.

  2. Description of the Related Art Conventionally, there is known a magnet holder that is suitable for posting a sheet or the like on an adherend surface such as a partition or a door formed of a magnetically adhesive material. As this magnet holder, for example, there is a type in which a concave portion is formed on one surface of a substantially disc-shaped holder main body, and a magnet is accommodated or embedded in the concave portion.

  The magnet holder is generally provided with a magnetic adhesive force that allows a small number of documents to be sandwiched between the adhesion surface and the operation burden when removing the magnet holder from the adhesion surface. Although it does not feel that much, it is necessary to use a magnet with extremely strong magnetic adhesive force when it is possible to sandwich a large number of documents or when it is a type equipped with a hook member that can suspend heavy objects. For this reason, the operation burden when removing the magnet holder from the attachment surface becomes very heavy.

  By the way, there has been proposed a magnet holder of a type that utilizes the principle of leverage when removing the magnet holder from the adherend surface (for example, see Patent Document 1). The magnet holder described in Patent Document 1 is provided with a moving member (operating member) in a holder main body provided with a magnet, and by operating the operating member for a predetermined time, an action of an insulator is generated and the magnet is covered. It is configured to gradually move away from the landing surface.

JP 2003-165292 A

  However, the magnet holder described in Patent Document 1 has a configuration in which an action point or an action area when using the lever principle is in direct contact with the adherend surface. For this reason, every time the operating member is operated, the operating member and the adherend surface rub against each other, which causes a disadvantage that the rubbed surface damages the adherend surface.

[Object of invention]
The present invention has been devised by paying attention to such inconveniences, and the purpose of the present invention is to reduce the adhesion area or area of the magnet to the adherend surface without damaging the adherend surface. It is an object of the present invention to provide a magnet holder that can be easily detached from the adherend surface.

In order to achieve the above object, the present invention provides a magnet that adheres to an adherend surface, a holder body that holds the magnet, and the holder body and the adherend surface. An intermediate member provided so as to be relatively displaceable, and an operation member for applying a pressing force to the intermediate member,
When the operation member applies a pressing force to the intermediate member, the holder main body is provided so as to be angularly displaced and away from the adherend surface.

  It is preferable that the intermediate member is located around a magnet along the outer periphery of the holder body, and is provided so that a part of the operation member is positioned on the intermediate member and the pressing force is applied.

  Further, the operation member is supported by the holder main body so as to be relatively rotatable, and has a configuration in which the operation member is positioned along the adherend surface when the magnet is bonded to the adherend surface.

  Further, the holder body has a substantially circular shape in plan view, and the operation member has a substantially C-shaped planar shape surrounding a substantially half region in the circumferential direction of the holder body, and both side portions of the C-shape are It is possible to adopt a configuration in which the holder body is rotatably supported. At this time, it is preferable that the central portion of the operation member is formed as an enlarged region protruding to the opposite side of the holder body, and the enlarged region is configured as an operation region.

  Moreover, you may take the structure that the hook member located in the other side of the said operation member is further included. In this case, the hook member can be rotatably supported by the operation member.

According to the present invention, when the operation member is operated to apply a pressing force to the intermediate member, a reaction force is applied to the holder body to move away from the attachment surface by the pressing force. This reaction force acts in a direction that causes the magnet to be angularly displaced so as to gradually move away from the adherend surface, so that the amount of angular displacement of the magnet can be increased as the amount of operation of the operating member increases. If the angle is displaced to a position where the adhesion area with the attachment surface is greatly reduced, the entire magnet holder can be detached from the attachment surface simply by pulling it away from the attachment surface.
In addition, since the pressing force by the operation member is directly applied to the intermediate member by contact with the intermediate member, the adherend surface and the operation member do not rub against each other, and when the friction occurs, Scratches on the wearing surface can be reliably prevented.

  Furthermore, since the operation member is positioned along the adherend surface with the magnet adhered to the adherend surface, the operation member does not protrude forward from the adherend surface and is present in the way It will never be.

  Further, when the operation member has a substantially C-shaped planar shape and both side portions are supported by the holder body, the pressing force can be applied to the intermediate member at two locations. Become. In addition, by adopting a configuration in which the central portion of the operation member is enlarged and used as an operation region, it is possible to ensure a long distance between the fulcrum corresponding to the rotation center of the operation member and the action point for applying the operation force. The operation force can be reduced accordingly.

  Furthermore, when a hook member is provided, it is possible to select a usage mode in which a predetermined object is suspended and held on the hook member in addition to a usage mode in which a document or the like is sandwiched between the magnet and the adherend surface. It becomes.

The intermediate member 12 in the present embodiment is a resin molded product, and therefore the main body 35 and the shaft 40 can be integrally molded.

  The operation member 13 applies a pressing force to the intermediate member 12, and is used to cause the holder body 11 to be angularly displaced and pulled away from the adherend surface S when the pressing force is applied. The operation member 13 is formed of a resin material and is supported by the holder body 11 so as to be relatively rotatable as shown in FIGS. 1, 12 to 14, and the magnet M adheres to the adherend surface S. When it is, it is provided so as to be positioned substantially parallel along the adherend surface S.

Has been. In addition, as shown in FIGS. 3 and 13, the operation member 13 is substantially parallel to the adherend surface S, and is substantially at the same height as the rotation center of the operation member 13. The side end face 13B located on the adherend surface S side with the lower position and the lower end face 13C connected to the side face 13B are in contact with the intermediate member 12 to provide a force point region for applying a pressing force. A concave portion 13D is formed on the base side of the operation region 13A, and the attachment portion 30 of the holder body 11 is positioned in a state where the magnet holder 10 is bonded to the adherend surface S. ing.

  As shown in FIGS. 1 and 16, the hook member 14 is formed by bending a single metal wire. The hook member 14 includes a pair of rotating shaft portions 50 and 50 that are respectively inserted into bearing holes 44 formed in the outward projecting portions 42 of the operation member 13, and downward from the outer ends of the rotating shaft portions 50 and 50. And a pair of arm portions 52, 52 extending in a direction approaching each other, and a hook-like portion 54 that is bent forward and upward from the lower portion of these arm portions 52 and is connected to each other. The hook member 14 is provided on the side opposite to the operation member 13 in the use state. Further, the hook member 14 is detachable from the bearing hole 44 of the rotary shaft portion 50, and does not prevent removal depending on the case.

  The magnet M has a through hole 55 at the center, and can be attached by inserting a bolt B into the through hole 55 and screwing the bolt B into the central tube 22 of the magnet body 11. . The magnet M may have a disk shape without the through-hole 55. In this case, the magnet M can be dealt with by making the holder body 11 and the magnet M relative to each other.

  Next, a method of using the magnet holder 10 will be described with reference to FIGS.

  First, in a use state in which the magnet holder 10 is bonded to the adherend surface S, as shown in FIG. On the other hand, the hook member 14 is in a state where the arm portion 52 is substantially parallel to the adherend surface S and is located below the center portion of the holder body 11, and the hook-like portion 54 is at the lowest position. It will be in the state which can suspend the target object which is located in FIG. Further, the intermediate member 12 is interposed between the step portion forming the small diameter portion 27 of the holder main body 11 and the adherend surface S, and the relative rotation center between the intermediate member 12 and the holder main body 11 is located above. It will be. As the magnet M in the present embodiment, a magnet having a magnetic adhesive force sufficient to prevent the holder body 11 from being directly gripped and pulled away from the adherend surface S is employed.

  Therefore, when the magnet holder 10 is removed from the adherend surface S, for example, four fingertips excluding the thumb are inserted into the space on the adherend surface S side of the operation region 13A of the operation member 13 and directed to the left side in FIG. It is necessary to apply operating force. By applying this operating force, the lever acts, and the operating member 13 attempts to rotate counterclockwise in FIG. 3 with the center of the bearing portion 28 of the holder body 11 as the center of rotation. 13B gives a pressing force to the surface of the intermediate member 12. Then, as the contact point due to the pressing moves away from the rotation center, the holder body 11 receives the reaction force of the pressing force and the lower side is lifted in a direction away from the adherend surface S and is displaced relative to the intermediate member 12. As a result, the adhesive force by the magnet M is gradually reduced.

  As shown in FIGS. 17 and 18, the adhesive force by the magnet M is extremely small by rotating the lower end surface 13 </ b> C of the operation member 13 to a position where it is in contact with the intermediate member 12 in a substantially parallel state. In this state, the magnet holder 10 can be detached from the adherend surface S by pulling the operating member 13 away from the adherend surface S.

  In addition, since the magnetic adhesive force of the magnet M in this embodiment is very strong, when attaching the magnet holder 10 to the to-be-adhered surface S, the tendency to try to adhere | attach strongly strongly is brought about instantaneously. Therefore, in order to prevent the entire bonding surface of the magnet M from being bonded at the same time, the operation member 13 is rotated in advance to a certain angular position to temporarily hold the entire surface simultaneous bonding, and then the operation member 13 is attached. If the operation is performed so as to be parallel to the surface S, it is possible to slowly shift to the entire surface adhesion, and it is effective to prevent a finger from being inadvertently sandwiched between the holder body 11 and the adherend surface S. Can be avoided.

  As described above, according to the present invention, even if the magnet M has a strong magnetic adhesive force, the adhesive force is gradually weakened by the operation of the operation member 13 to reduce the burden while reducing the burden. It is possible to provide a magnet holder 10 that can be detached from the wearing surface S.
