Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a magnet holder, and more particularly, to a magnet holder that can be easily removed from an adherend surface even when a magnet having a strong adhesive force is used.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there is known a magnet holder that can be pasted in such a manner that a sheet is sandwiched by using a whiteboard, a partition, or the like as an attachment surface. This type of magnet holder is configured by fixing a magnet on the back side of a holder body having a planar piece shape or a long piece shape. According to such a magnet holder, it is possible to attach and remove the paper to and from the adherend surface very easily, and it is not necessary to use an adhesive tape or the like. Transfer of the agent can also be avoided.
[0003]
[Problems to be solved by the invention]
However, 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 sheet, one having a strong adhesive force must be used. Also, when a large number of sheets are pasted, one having a strong adhesive force is desired.
[0004]
However, when a magnet holder of a type having a strong adhesive force is used for an adherend having no cloth material, such as a white board, the adhesive force is too strong and it is extremely difficult to remove it. Inconvenience.
[0005]
OBJECT OF THE INVENTION
The present invention has been devised by paying attention to such inconveniences, and an object of the present invention is to provide a magnet holder that can be easily detached even if it has a strong magnetic adhesive force.
[0006]
[Means for Solving the Problems]
To achieve the above object, the present invention provides a magnet holder comprising a holder body and a magnet that is held by the holder body and adheres to a predetermined adherend surface.
The holder body includes a cylindrical portion, a top portion connected to the upper portion of the cylindrical portion is constituted by a pair of operating portions,
A split groove is formed on the top, and the operation portions are formed on the holder body by forming the split groove.
By holding each operation part with a finger and applying a force in a direction substantially parallel to the adherend surface, the holder body is deformed or displaced so as to narrow the width of the split groove, and the outer peripheral side of the lower surface of the operation part is covered. A configuration is adopted in which the magnet is lifted in a direction away from the attachment surface and the magnet is separated from the attachment surface so that the adhesion of the magnet to the attachment surface can be released. With such a configuration, by applying an external force to the operating portion and deforming it, the force required for removal can be reduced and the magnet can be removed from the adherend surface. In other words, the adhesive state is released by deforming a part of the holder body, rather than exerting a direct external force to peel off the magnet to the opposite side with respect to the adherend surface. By adopting a design that enables the holder on the holder body side, the magnet holder adhered to the adherend surface can be removed smoothly. Further, since an external force can be applied in such a direction as to pick the magnet holder, the magnet holder does not fall on the floor surface or the like after the adhesive force is released.
[0007]

In these drawings, the magnet holder 10 includes a holder main body 11 and a pair of magnets 12 and 12 held by the holder main body 11, and the holder main body 11 is constituted by an integrally molded product made of an appropriate resin material. ing. The holder body 11 includes a cylindrical portion 15 and a top portion 16 that is connected to the upper portion of the cylindrical portion 15 via a gentle outer peripheral curved surface and is provided with a relatively large diameter. As shown in FIGS. 2 and 6, a partition wall portion 17 extending in the radial direction is provided in the cylindrical portion 15, and a magnet having a substantially semicircular shape in plan view on both sides with the partition wall portion 17 in the middle. Twelve holding spaces S, S are formed. Here, the top portion 16 is formed with a split groove 20 along the extending direction of the partition wall portion 17 with the substantially middle height position of the partition wall portion 17 as a bottom portion. A pair of operation units 21 and 21 is formed on the main body 11. As shown in FIG. 6, the lower surface 17 </ b> A of the partition wall portion 17 is positioned substantially on the same plane as the lower surface 15 </ b> A of the tubular portion 15.
[0011]
The magnets 12 and 12 are held in the holding spaces S and S so as not to fall off by press-fitting into the holding spaces S and S or through an appropriate adhesive. The thicknesses of the magnets 12 and 12 are set so that the lower surface 12A slightly protrudes from the lower surface 15A of the cylindrical portion 15 in a state where the magnets 12 and 12 are held in the holding spaces S and S.
[0012]
As shown in FIG. 6, the magnet holder 10 is bonded so as to sandwich the paper P in a state where the paper P is arranged on the adherend surface of the adherend A. The magnet holder 10 can be removed from the adherend A by, for example, grasping the operation units 21 and 21 in the direction of the arrow with the thumb and forefinger as shown in FIG. That is, by applying a force in a direction substantially parallel to the adherend surface, each operation portion 21, 21 is deformed or displaced so as to narrow the width of the split groove 20, and the outer peripheral side of the lower surface thereof is the adherend surface and the paper surface. It floats away from P. Thereby, the adhesion area | region of the magnets 12 and 12 changes from a surface contact state until then to a line contact state, reduces an adhesion area, and enables the magnet holder 10 to be removed easily. At this time, the split groove 20 reaches a position near the lower end of the partition wall portion 17 and, as is clear from FIG. 6, has a depth that is more than half of the total thickness of the holder body 11. The approaching force will be light.
[0013]
Therefore, according to the first embodiment, even if the adhesive force of the magnets 12 and 12 is very strong, the adhesive force can be increased only by deforming the operation units 21 and 21 so as to approach each other. As a result, it is possible to lower the temperature, and the subsequent removal is extremely easy.
[0014]
Next, other embodiments of the present invention will be described. In the following description, the same or equivalent components as those in the first embodiment are denoted by the same reference numerals as necessary, and the description is omitted or simplified.

In this embodiment, the position of the lower surface 17A of the partition wall portion 17 (see FIG. 11) in the magnet body 11 is slightly above the position of the first embodiment, and the pair of magnets 12 and 12 are abutted against each other. It is characterized in that the contact area with respect to the adherend surface of the body A is increased. Therefore, the magnets 12 and 12 are provided with thin plate-like extensions 12B and 12B on the bonding surface side, and cover the lower surface 17A of the partition wall 17 in a state where these extensions 12B and 12B face each other. It has become.
[0016]
According to such an embodiment, the same operation and effect as those of the first embodiment can be obtained. However, according to the second embodiment, the diameter of the cylindrical portion 15 is the same as that of the first embodiment. Even so, the area having the adhesive force is further expanded.
[0017]
[Third embodiment]
13 to 21 show a third embodiment of the present invention. In this embodiment, the holder main body 11 is constituted by a cylindrical portion 15 and a top portion 16 positioned at the upper end of the cylindrical portion 15, and is substantially U-shaped in plan view from the lower end of the cylindrical portion 15 to the top portion 16. The operation parts 21 and 21 are formed at symmetrical positions of the holder body 11 by providing split grooves 20 and 20 that are substantially U-shaped. Specifically, the split grooves 20 and 20 include linear groove portions 20A and 20A extending to positions substantially parallel to each other at the top portion 16, radial groove portions 20B and 20B extending substantially radially from both ends of each linear groove portion 20A, and the like. The longitudinal groove portions 20C and 20C extend from the outer ends of the radiation groove portions 20B and 20B to the lower end of the cylindrical portion 15, and the operation portions 21 and 21 that form a pair are formed by the formation of the split groove 20. ing. Each operation portion 21 is provided with a raised portion 24 along the circumferential direction on the outer peripheral surface side, and is provided with a shape having a ridge portion 25 on the lower end surface.
[0018]
In the split groove 20, the radial groove 20B and the vertical groove 20C are open to the inside and outside of the holder body 11, but the straight groove 20A is a groove in which a thin hinge portion 23 is formed as shown in FIG. Thus, when an external force is applied from the outside to the inside, the lower end side of the operation unit 21 is shifted inward and tilted.
[0019]
On the lower side of the inner peripheral surface of the cylindrical portion 15, a rib 26 is provided for holding the magnet 12 and obtaining a certain strength. In addition, a spacer cylinder 27 is provided at a substantially central portion on the lower surface side of the top portion 16, and the magnet 12 is received and held in a lower region of the spacer cylinder 27. The magnet 12 is provided in a substantially disk shape with the upper end portion (adhesion surface side) slightly larger in diameter, and the magnet 12 forms a gap between the inner peripheral surface of the operation portion 21. Thus, the operating portion 21 is provided in a size (diameter) that allows the inclination of the operating portion 21.
[0020]
As shown in FIGS. 20 and 21, in a state where the magnet holder 10 is adhered to the adherend A with the paper P in between, the operation portions 21 and 21 are substantially parallel to the adherend surface from the outside to the inside. When a force is applied in any direction, the operation unit 21 has its lower end shifted inward with the position of the hinge 23 as the center of rotation. At this time, the position of the ridge portion 25 is located closer to the adherend A than the position of the adhesion surface of the magnet 12, and the magnet 12 is separated from the paper P, thereby releasing the adhesive force.
[0021]
Accordingly, the third embodiment can provide the same effects as those of the above-described embodiments. In addition, in the same Example, while providing the taper surface to which a skirt width becomes wide as it goes below on the lower inner peripheral surface of the operation part 21, the structure which provides the taper surface corresponding to this on the lower outer peripheral surface of the magnet 12 is provided. In this way, a part of the holder body 11, that is, the lower end can be inserted between the magnet 12 and the adherend surface.
[0022]
【The invention's effect】
As described above, according to the present invention, the operation part to which an external force is applied is deformed and the adhesion of the magnet to the adherend surface is provided so as to be releasable. The force required for removal can be reduced and the magnet can be removed from the adherend surface. That is, instead of applying a direct external force to peel off the magnet on the opposite side of the adherend surface, the adhesive state is released by deforming a part of the holder body, so that the deformation By adopting a design that enables the holder main body side, the magnet holder adhered to the adherend surface can be smoothly removed. Further, since an external force can be applied in such a direction as to pick the magnet holder, the magnet holder does not fall on the floor surface or the like after the adhesive force is released.
