Description

  The present invention relates to a magnet holder, and more particularly to a magnet holder that can be easily removed from a surface to be bonded even when a magnet having a strong adhesive force is used.

  2. Description of the Related Art Conventionally, there is known a magnet holder that is attached in such a manner that a sheet or the like is sandwiched between adherend surfaces such as a white board and a partition. As shown in FIG. 9, the magnet holder 100 includes a holder main body 102 made of resin or the like, and a magnet 104 attached to the bonding surface side of the holder main body 102 and bonded to the bonded surface. If this magnet holder 100 is used, paper or the like can be attached to the adherend surface.

  By the way, the partitions that are often introduced in recent offices have a laminated structure of a metal member used as a core or frame and a cloth material that makes up the surface of the partition, so a magnet holder is attached to the surface of the cloth material. When a sheet is pasted using a magnet, a magnet having strong adhesive strength must be used. In addition, a magnet having a strong adhesive force is also required when a large number of sheets are pasted.

  However, when a magnet holder with a strong adhesive force is used on a surface to be bonded that does not have a cloth material, such as a whiteboard, the adhesive force is too strong and it is extremely difficult to remove it. Will occur.

Therefore, conventionally, as shown in FIG. 10, the holder main body 202 and the magnet 204 attached to the holder main body 202 and bonded to the adherend surface L are provided. There has been proposed a magnet holder 200 in which an inclined portion 206 that is inclined upward is formed (see Patent Document 1 below). According to the magnet holder 200, the bonding surface side of the holder main body 202 is separated from the bonded surface L when bonded to the bonded surface L, and the vicinity of the outer edge portion on the side opposite to the bonded surface of the holder main body 202 when removed. Is pressed toward the adherend surface L, one inclined portion 206 comes into contact with the adherend surface L, and the magnet holder 200 is inclined with respect to the adherend surface L, so that the magnet holder 200 can be easily removed from the adherend surface L. Can be removed.

  However, with the configuration in which the inclined part is provided on the bonding surface side of the holder body, the posture of the magnet holder is not stable when removing the magnet holder from the bonded surface, and a finger is inserted into the bonding surface side of the holder body. There is a problem that it becomes difficult to hold the magnet holder with a finger and remove it from the adherend surface.

  Therefore, in consideration of the above circumstances, the present invention can stabilize the posture when removed from the adherend surface and can easily hold it with a finger or the like even if it has a strong magnetic adhesive force. It is an object of the present invention to provide a magnet holder that can be easily detached from an adhesive surface.

Invention of Claim 1 is a magnet holder which has a holder main body and a magnet which is provided in the holder main body and adheres to a predetermined adherend surface,
The magnet is fitted on the bonding surface side of the holder body, and a base portion that is substantially flush with the magnet and is formed so as to be groundable on the surface to be bonded is formed adjacent to the base portion. An inclined portion that is inclined so as to be largely separated from the adherend surface from the center portion of the holder main body toward the edge of the holder main body. It is characterized by having a finger hooking portion formed so as to protrude in the direction and capable of hooking a finger when the inclined portion comes in contact with the adherend surface.

According to the first aspect of the present invention, the magnet holder is bonded to the surface to be bonded, such as a white board, via the sticking member such as paper. Thereby, the state by which the sticking member was affixed on the to-be-adhered surface can be maintained.
Here, when removing the magnet holder from the adherend surface, if the holder body located on the inclined portion is pressed with a finger, a rotational moment acts on the magnet holder, and the inclined portion is grounded to the adherend surface (or a sticking member). The magnet holder is inclined by the inclination angle of the inclined portion. In addition, when the magnet holder is tilted, the tilting portion is grounded to the adherend surface via the sticking member, so that the sticking member does not fall from the adherend surface. When the magnet holder is tilted and the tilted portion contacts the surface to be bonded (or a sticking member), the finger is hooked on the finger hook portion formed to protrude outward from the tilted portion on the side surface of the holder body. The magnet holder can be easily removed from the adherend surface. In this way, even when using a magnet with a strong adhesive force, the magnet holder can be tilted in a state where the posture of the magnet holder is stabilized with a small force, and the magnet holder can be easily removed from the adherend surface. Can do.

And is formed so as to be inclined upward.

  According to the second aspect of the present invention, the anti-adhesion surface located on the opposite side of the thickness direction to the adhesion surface side of the holder body is formed so as to incline upward from the center of the holder body toward the edge. Therefore, when the anti-adhesion surface of the holder body is pressed, the finger does not slip on the anti-adhesion surface, and the pressing force is not distributed to the edge side. As a result, even when using a magnet with a strong adhesive force, it is possible to easily tilt the magnet holder and stabilize its posture simply by applying a slight force to the anti-adhesive surface of the holder body. Therefore, the magnet holder can be easily removed from the adherend surface.

  According to a third aspect of the present invention, in the magnet holder according to the first or second aspect, the holder main body is formed with a space for releasing heat generated during molding.

  According to the third aspect of the present invention, when the holder body is molded from resin, heat is generated from the holder body during molding. Here, since the surface area is increased by forming the space portion in the holder body, the holder body can be effectively cooled. As a result, the time until the magnet holder is manufactured can be greatly shortened, and the magnet holder can be mass-produced. In addition, by providing the space portion, the amount of resin can be reduced by the volume of the space portion, and the material cost can be reduced. Furthermore, if the amount of resin is reduced by providing a space portion, the amount of heat shrinkage of the holder main body is reduced, the shape of the magnet holder is not greatly collapsed, and it is possible to prevent deterioration of the design and commercial properties of the magnet holder. .

  The invention according to claim 4 is the magnet holder according to claim 3, wherein the space is formed in the vicinity of the magnet, and a part of the magnet is exposed in the space. To do.

  According to the invention described in claim 5, since the mark indicating the inclined portion is provided on the anti-adhesion surface located on the opposite side of the inclined portion of the holder body in the thickness direction, the pressing for inclining the magnet holder is performed. The location can be determined instantaneously.

  According to a sixth aspect of the present invention, in the magnet holder according to the fifth aspect, the mark is a protrusion or a depression.

  According to the invention described in claim 6, since the mark is a protrusion or a depression, the mark can be easily identified not only visually but also through tactile sense, and when the anti-adhesion surface of the holder body is pressed. It is possible to prevent the finger from sliding on the anti-adhesive surface.

  According to the present invention, even when having a strong magnetic adhesive force, the posture can be stabilized when removed from the adherend surface and can be easily held by a finger or the like. It can be easily removed.

That is, as shown in FIG. 6, when the magnet holder 10 is adhered to the adherend surface L, the distance from the adherend surface L of each of the inclined bases 18A and 18B is the radial direction from the radially inner side (center O side). It is formed so as to increase toward the outside. As shown in FIGS. 2 and 3, the inclined bases 18 </ b> A and 18 </ b> B are respectively formed so as to be recessed radially inward (center O side) of the base parts 16 </ b> A and 16 </ b> A.
Note that the portions 16C and 16D adjacent to the inclined bases 18A and 18B of the base portions 16A and 16B are inclined at substantially the same inclination angle as the inclination angles of the inclined bases 18A and 18B. In other words, the inclined bases 18A and 18B and the portions 16C and 16D adjacent to the inclined bases 18A and 18B of the base portions 16A and 16B form the same inclined surface.

  Moreover, as shown in FIG.1 and FIG.2, outer space part (space part) 20A, 20B, 22A, 22B is formed in each inclination base 18A, 18B and each base part 16A, 16B, respectively. By forming the outer space portions 20A, 20B, 22A, and 22B, the surface areas of the inclined bases 18A and 18B and the base portions 16A and 16B are increased. The outer space portions 20A, 20B, 22A, and 22B are all formed on concentric circles having different diameters.

  In addition, support portions 24A and 24B for supporting the magnet 14 are formed on the inner sides in the radial direction of the inclined bases 18A and 18B, respectively. A part of each of the support portions 24A and 24B is inclined at an inclination angle substantially the same as the inclination angle of the inclination bases 18A and 18B. That is, the support portions 24A and 24B have a function of supporting the magnet 14 and a function as an inclined portion. In addition, inner space portions (space portions) 26A and 26B are respectively formed at positions radially inward (center O side) of the base portions 16A and 16B and adjacent to the circumferential direction of the support portions 24A and 24B. ing. Thereby, a part of the outer peripheral surface of the magnet 14 is supported by the support portions 24A and 24B, and the magnet 14 is attached to the holder main body 12. In this state, the other outer peripheral surface of the magnet 14 The portions are exposed to the inner space portions 26A and 26B. By forming the inner space portions 26A and 26B, the surface areas of the base portions 16A and 16B are increased. In addition, each inner space part 26A, 26B is formed so that it may be located on the concentric circle where a diameter is the same.

  As shown in FIGS. 1, 2 and 5, finger holders 28A and 28B are formed on the outer peripheral side of the holder body 12. The finger hook portions 28A and 28B are formed so as to protrude greatly outward in the radial direction from the inclined bases 18A and 18B. Further, each of the finger hook portions 28 </ b> A and 28 </ b> B is formed to be inclined upward from the center portion O of the holder main body 12 toward the edge of the holder main body 12. Further, as shown in FIG. 1, a plurality of protrusions (marks) 30 </ b> A are provided on the surfaces of the finger hook portions 28 </ b> A and 28 </ b> B on the opposite sides of the inclined bases 18 </ b> A and 18 </ b> B in the finger hook portion thickness direction. 30B is formed. The protrusions 30A and 30B are located further radially outward than the radially outer end portions of the inclined bases 18A and 18B. Note that the marks are not limited to the protrusions 30A and 30B. For example, depressions (not shown) formed on the surfaces of the finger hook portions 28A and 28B or the surfaces of the finger hook portions 28A and 28B are provided. Marking may be used.

  As shown in FIGS. 4 and 5, the anti-adhesion surface located on the opposite side in the thickness direction from the adhesion surface side of the holder body 12 is formed in a concave shape. Accordingly, the finger hook portions 28A and 28B are formed so as to be inclined upward in a side view (see FIG. 5) from the center O of the holder main body 12 toward the radially outer side.

  Next, the operation of the magnet holder 10 according to the present embodiment will be described.

As shown in FIG. 6, the magnet holder 10 is bonded to an adherend surface L such as a white board via a sticking member such as paper P. Thereby, it is possible to maintain the state in which the paper P is stuck on the adherend surface L.
When removing the magnet holder 10 from the adherend surface L, as shown in FIG. 7, when one finger hooking portion 28A formed on the edge side of the holder body 12 is pressed with a finger, a rotational moment acts on the magnet holder 10. Then, one inclined base 18A comes in contact with the adherend surface L, and the magnet holder 10 is inclined by the inclination angle of the inclined base 18A. Thereby, a part of the holder body 12 (the other inclined base 18B side) is lifted so as to largely protrude from the adherend surface L. At this time, when the magnet holder 10 is tilted, the tilting bases 18A and 18B are in contact with the paper P, so that the paper P does not drop from the adherend surface L.

Further, as shown in FIG. 7, after the one tilting table 18A comes in contact with the adherend surface L and the holder body 12 on the other tilting table 18B side is lifted, the one on the other tilted table 18B side that has been lifted is further provided. If the finger hook portion 28B is further lifted with a finger or the like, the inclined base 18A is recessed radially inward from the base portion 16A, so that one finger hook portion 28A is attached to the adherend surface L as shown in FIG. And ground. Thereby, the magnet holder 10 is further tilted, and the holder body 12 on the other tilt base 18B side is further lifted, and the tilt angle of the magnet holder 10 with respect to the adherend surface L can be further increased.
As described above, the magnet holder 12 can be tilted in two stages, and the magnet holder 10 can be tilted with the posture of the magnet holder 10 stabilized even when the magnet 14 having a strong adhesive force is used. The magnet holder 10 can be easily detached from the adherend surface L.
Further, when the magnet holder 10 is tilted when the magnet holder 10 is detached from the adherend surface L, it is possible to place a finger on one of the finger hook portions 28A and 28B. As a result, the magnet holder 10 can be picked up more easily, and the magnet holder 10 can be removed from the adherend surface L more easily.

  In addition, since each of the inclined bases 18A and 18B is inclined so as to be separated from the adherend surface L from the radially inner side to the radially outer side, when removing the magnet holder 10 from the adherend surface L, first, The inclined base 18A comes into contact with the adherend surface L. At this time, since the surface of the finger hook portion 28A is inclined upward from the radially inner side (center O side) toward the radially outer side (edge side), the finger does not slip on the surface of the finger hook portion 28A. The pressing force that presses the finger hook portion 28A is not dispersed radially outward. Thereby, even when the magnet 14 having a strong adhesive force is used, the magnet holder 10 can be easily inclined with respect to the adherend surface L only by applying a slight force to the finger hook portion 28A. Since the posture can be stabilized, the magnet holder 10 can be easily detached from the adherend surface L.

  Further, since the protrusions 30A and 30B are formed on the surfaces of the finger hook portions 28A and 28B, the protrusion portions 30A and 30B can have a mark function as a pressing portion of the finger hook portions 28A and 28B. In addition, the protrusions 30A and 30B can also have a function of preventing slippage. Thereby, each finger hooking part 28A and 28B can be discriminate | determined instantaneously, and it can prevent that a finger | toe etc. slip on finger hooking part 28A and 28B when pressing on each finger hooking part 28A and 28B.

  Furthermore, when the holder main body 12, the base portions 16A and 16B, and the inclined bases 18A and 18B are molded from resin, heat is generated from the holder main body 12, the base portions 16A and 16B, and the inclined bases 18A and 18B at the time of molding. To do. Here, by providing the outer space portions 20A, 20B, 22A, 22B and the inner space portions 26A, 26B, the surface area of the holder body 12, the base portions 16A, 16B, and the inclined bases 18A, 18B is increased. The main body 12, the base portions 16A and 16B, and the inclined bases 18A and 18B can be effectively cooled. As a result, the time until the magnet holder 10 is manufactured can be greatly shortened, so that the magnet holder 10 can be mass-produced. In addition, by providing the outer space portions 20A, 20B, 22A, 22B and the inner space portions 26A, 26B, the amount of resin can be reduced by the volume of each space portion 20A, 20B, 22A, 22B, 26A, 26B. Material costs can be reduced. Further, since the amount of resin can be reduced by providing each space portion 20A, 20B, 22A, 22B, 26A, 26B, the amount of heat shrinkage of the holder main body 12, each base portion 16A, 16B, and each inclined base 18A, 18B can be reduced. It becomes small and the shape of the magnet holder 10 does not collapse greatly after resin molding, and the design and commercial properties of the magnet holder 10 can be prevented from being lowered.

  Further, since a part of the outer peripheral surface of the magnet 14 is exposed in the inner space portions 26A and 26B, the magnet 14 and the holder main body 12 can be easily moved by inserting a tool into the inner space portions 26A and 26B. Can be separated.

  In the present embodiment, the magnet holder 10 has been described by taking a circular shape in plan view as an example. However, the present invention is not limited to this. For example, a rectangular shape such as a square or a diamond shape may be used. Good.
