Abstract

Provided is a technique in which the magnet is hard to slide against the surface to be adsorbed without increasing the adsorption force of the magnet.

The magnet structure includes a magnet body 300 attached to the base 100 and an elastic body 400. The magnet body 300 includes a planar adsorption surface 310, and the elastic body 400 includes a pressing surface 430 that is planar and located at a position that is more prominent than the adsorption surface 310. When the adsorption surface 310 of the magnet body 300 is adsorbed on the adsorption target surface X, the elastic body 400 is crushed between the adsorption surface X and the adsorption surface X, and becomes flush with the adsorption surface 310. When the magnet structure is to be slid to the surface to be adsorbed X, the frictional force between the elastic body 400 and the surface to be adsorbed X is generated, and the frictional force is lost and the frictional force is excavated. Therefore, the magnet structure system is difficult to slide.

Description

magnet

The invention relates to a magnet.

Magnets that can be attracted to metals or magnets by magnetic force have been known since ancient times. The magnet is used in various scenes, for example, for fixing the surface of the adsorbed surface which is made of a metal such as iron which can be adsorbed by a magnet.

As one of the specific examples, a magnet clip can be cited. The magnet holder includes: a magnet; and a clip that is fixed to the magnet and can be attached to the magnet by elastically holding a predetermined object (an example of a paper by handwriting or printing a certain content or the like). The magnet is attached to the object to be adsorbed by the clip, and the magnet is attached to the surface to be adsorbed, whereby the magnet is detachably fixed to the surface to be adsorbed.

The magnet clip is formed so that the object to be adhered can be intruded, and the object to be fixed can be indirectly attached and detached via the magnet holder. Moreover, the fixing system that is detachably attached to the surface to be adsorbed does not substantially damage the surface to be adsorbed. Because of that advantage, magnet clips are very popular.

However, when the weight of the object exceeds a certain level, the magnet of the magnet holder has insufficient adsorption force to the adsorbed surface, and adsorption occurs. The case where the magnet of the adsorbed surface is slid in the direction in which the force acts (generally, the direction in which the gravity acts in the downward direction).

In order to prevent this, the magnet included in the magnet clip may be an anisotropic magnet or the like to increase the magnetic force of the magnet. However, magnets having a large magnetic force are generally expensive, and the product line in the field where the price of the magnet clip is highly competitive may not be adopted.

In addition to attaching the clip to the magnet holder of the magnet, there is a magnet case in which the case for accommodating the predetermined object is attached to the magnet, or a magnet hook for locking the predetermined object to the magnet. Wait. Further, in those magnet boxes and magnet hooks, when the weight of the object becomes heavy, the magnet slides on the adsorbed surface.

In other words, even if the adsorption force of the magnet is not increased, the technique of increasing the force at which the magnet starts to slide on the adsorbed surface can be of great value.

However, that kind of technology is not yet known.

An object of the present invention is to provide a technique for increasing the force at which a magnet starts to slide on a surface to be adsorbed without increasing the adsorption force of the magnet, that is, even if the adsorption force of the magnet is not increased. It is also possible to make the magnet difficult to slide on the surface to be adsorbed.

As an invention to solve the above problems. The inventors propose the following invention.

The present invention relates to a magnet structure comprising: a magnet body having an adsorption surface which is predetermined to be a plane which is adsorbed by an adsorption surface having a predetermined plane which is adsorbed by a magnetic force, and has a magnetic force; Elastomer a protruding portion is disposed and has elasticity. The protruding portion is disposed in the vicinity of the adsorption surface, and protrudes from a plane of the magnet body including the adsorption surface, and when the adsorption surface is forced to be adsorbed on the adsorption surface, The adsorbed surface is pressed and crushed.

The magnet structure system of the present invention has a magnet body having a planar adsorption surface and having a magnetic force. The magnet structure system of the present invention has an elastomer in addition to the magnet body. The elastic system has a projection that protrudes from a plane of the magnet body including the adsorption surface. The elastic system has elasticity, and the above-mentioned protruding portion is pressed by the suction surface to be crushed when the adsorption surface is forced to be adsorbed on the adsorption surface.

This magnet structure system is the same as that of a general magnet, and is used to adsorb the adsorbed surface by the adsorption force of the magnetic force of the magnet body. When the adsorption surface of the magnet body is forced to be adsorbed on the surface to be adsorbed, the elastic body, more precisely, the protruding portion is pressed by the adsorption surface, whereby the elastic body is compressed.

When a force parallel to the plane is applied to an object placed on a certain plane, as is well known, a frictional force is generated between the plane and the object, and a hard object such as metal is used on both the plane and the object. The friction acting between them is called the traction force according to Coulomb's law. On the other hand, in the case where the material system is an elastomer such as rubber, the deformation loss friction force and the excavation friction force act between the plane and the object. Roughly speaking, the deformation loss friction force and the excavation friction force are frictional forces generated by the elastic body entering minute irregularities existing on the surface of the plane, and the greater the elasticity of the elastic body, the greater the frictional force. In addition to the frictional force, the magnet structure system also uses a mechanism different from the deformation loss friction force and the excavation friction force as frictional force, thereby suppressing the sliding of the adsorbed surface. Further, in the magnet structure system, if the magnetic force of the magnet body is the same as that of a general magnet, it is more difficult to slide on the adsorbed surface, and if it is made to make the difficult sliding property to the adsorbed surface and the conventional magnet phase Similarly, the magnetic force of the magnet body is weaker than the conventional magnet.

In other words, the magnet structure system can make it difficult to slide on the surface to be adsorbed without increasing the adsorption force of the magnetic force of the magnet body.

The magnet system of the present invention has a planar adsorption surface. The adsorption surface system may have a flat surface mounted on the same plane, and may be divided into a plurality of pieces under the restriction, or may have a concave portion or a hole in a part thereof. For example, the magnet system may be fixed to the main body as will be described later. However, the concave portion or the hole is provided on the adsorption surface of the magnet body for the fixation, and the surface of the adsorption surface is not hindered.

In addition, the term "adsorption" in the present invention does not necessarily mean a state in which the adsorption surface of the magnet body is in contact with the surface to be adsorbed, and a state in which the adsorption surface of the magnet body is close to the surface to be adsorbed or has a slight gap, and the magnet The body is fixed in a state of being detachable from the adsorption surface. In some types of magnets, for example, a magnet body is embedded in a concave portion of a metal casing having a concave portion mounted on a certain plane at its edge, but the entire magnet body is completely fitted into the concave portion, and the adsorption surface of the plane is located at the edge of the concave portion. The above-mentioned plane is mounted at a slightly rearward position. In the magnet, when the magnet or the magnet body is attracted to the surface to be adsorbed, the edge of the concave portion abuts against the surface to be adsorbed, but the adsorption surface of the magnet body does not abut against the surface to be adsorbed. However, even if the adsorption surface of the magnet body does not contact the surface to be adsorbed, the magnet body is fixed to the surface to be adsorbed. This configuration is typically seen in magnet bodies from conventionally existing magnet clips.

Further, in the present invention, the protruding portion of the elastic body protrudes from the plane containing the adsorption surface of the magnet body, which means that when the adsorption surface of the magnet body is held parallel to the surface to be adsorbed while being adsorbed on the surface to be adsorbed, The protruding portion of the elastic body contacts the adsorbed surface earlier than the adsorption surface of the magnet body. As long as it is constructed in this way, it is outstanding The shape of the department.

The elasticity of the elastic body should be set so as not to impair the adsorption surface of the magnet body to the adsorbed surface, and the protruding portion of the elastic body is crushed by the adsorption surface when the adsorption surface of the magnet body is forced to be adsorbed on the adsorbed surface. The degree of flexibility. That is, the elastic system is soft to the extent that it is preferred.

Further, as described above, if the elasticity of the elastic body is larger, the magnet structure system becomes more difficult to slide on the surface to be adsorbed. The elastic system can be made to have a modulus of elasticity, for example, less than 40 MPa. As long as the elastic body has such a degree of elasticity, the magnet structure combined with the general-purpose magnet body and the elastic body can sufficiently obtain the effect of preventing slippage of the surface to be adsorbed.

The elasticity of the elastomer is such that the elastomer is rubber, and the hardness is less than Hs70. The above condition in which the modulus of elasticity is smaller than 40 MPa is a case where the elastomer is rubber, and is substantially synonymous with a hardness smaller than Hs70. By making the elastic body have elasticity in this range, the magnet structure combined with the general-purpose magnet body and the elastic body can sufficiently obtain the effect of preventing slippage of the surface to be adsorbed.

The material of the elastomer is a natural or synthetic difference. Rubber may also be used, or a resin such as PVC (polyvinyl chloride) may be used, or ruthenium may also be used. Any of the materials used to change the elasticity thereof has been established, and using those techniques, the elasticity of the elastomer can be set to an appropriate range for obtaining the effects of the present invention.

Further, regardless of the material, the elastic system may be formed into a sponge shape. By adopting the sponge-like structure, the elasticity of the elastic body can be appropriately changed, and the fine unevenness of the elastic body can be appropriately used, and the difficulty in sliding the adsorbed surface can be expected to increase.

As described above, the magnet structure system of the present invention includes a magnet body and an elastomer. Alternatively, the magnet body and the elastic system may be fixed together to fix the magnet body and the body of the elastic body. Thereby, the relative positional relationship between the magnet body and the elastic body can be maintained in a desired state.

In the case where the magnet structure includes the body, the system may include a hole having an annular edge mounted on a virtual surface that is a virtual plane. In this case, the magnet body and the elastic system are in a plane, the adsorption surface is coincident with the virtual surface or located slightly behind the virtual surface, and the protrusion is embedded in the cavity from the virtual surface. internal. By embedding the elastomer in the cavity of the body, the side surface of the elastic body is prevented from being contaminated or damaged, and since the hole in which the magnet is embedded in the body is used in the conventional method, the manufacture of the magnet structure does not become difficult. In addition, the general "hole" often means the bottom, but the "hole" in this case also contains a bottomless hole. Further, a part of the side of the hole may be opened. In the case where one of the holes is open, the edge does not exist in the portion of the side of the hole that is open. That is, the edge system of the present invention is not necessarily an endless loop.

When the adsorption surface of the magnet body coincides with the virtual surface, when the adsorption surface is adsorbed on the adsorption surface, the adsorption surface is in contact with the adsorption surface, and the adsorption surface of the magnet body is located slightly behind the virtual surface. When the adsorption surface is adsorbed on the adsorbed surface, the adsorbed surface does not contact the adsorption surface (generally, when the adsorption surface is adsorbed on the adsorbed surface, the interval between the two is about 0.5 mm).

A method of fixing the magnet body and the elastic body to the body can be appropriately selected. The magnet system is fixed to the body, for example, by screws or adhesives. The elastic system is fixed to the body, for example, by adhesion. Further, the following configuration may be adopted in which the concave portion is provided on one side of the main body and the elastic body, and the convex portion is provided on the main body and the elastic body. On the other hand, the elastic body is fixedly attached to the main body by locking the convex portion to the concave portion. In this manner, since the step of bonding can be omitted, the manufacturing cost of the magnet structure can be suppressed.

The elastic body of the magnet structure of the present invention and the shape of the protruding portion thereof are not particularly limited, and the protruding portion of the elastic body may have a pressing surface which is a plane parallel to the adsorption surface. According to the Coulomb's law, the traction friction system becomes larger in proportion to the force exerted by the object on the plane, and is not affected by the area on the surface when the object is in contact with the plane, but the frictional force and the excavation friction force and the object are caused by the deformation loss. When the force applied to the plane and the area on the outer surface when the object is in contact with the plane become larger, the magnet structure is attracted to the surface of the protrusion by the contact surface of the protrusion. When the surface is adsorbed, the deformation loss friction force and the excavation friction force can be increased. This of course means that the magnet structure is difficult to slide against the adsorbed surface.

In the case where the protruding portion of the elastic body has a pressing surface, it is preferable that the pressing surface protrudes from the adsorption surface of the magnet body in the following range. In the case of the following example, when the pressing surface of the elastic body is forced to be adsorbed on the adsorption surface by the adsorption surface of the magnet body, in principle, if the adsorption surface abuts against the surface to be adsorbed, it is flush with the adsorption surface. If the adsorption surface does not contact the surface to be adsorbed, it is substantially flush with the adsorption surface.

For example, the pressing surface may be retracted more than 0.2 mm when the adsorption surface of the magnet body is forced to be adsorbed on the surface to be adsorbed. According to the experimental results of the experimental work on the magnet structure by the present inventors, when the adsorption surface is adsorbed on the surface to be adsorbed, it is not crushed to such an extent that the anti-slip effect cannot be sufficiently exhibited.

Alternatively, the pressing surface is forced to be adsorbed on the adsorption surface of the magnet body. In the case of a face, it retreats in a range of more than 0.2 mm and less than 2 mm. If the adsorption surface of the magnet body is forced to be adsorbed on the surface to be adsorbed, and the elastic member is to be retracted more than 2 mm, if the elastic body does not use a relatively soft material, or the magnetic force of the magnet body becomes relatively strong, or both, It is difficult to make the adsorption surface and the pressing surface the same surface, and it is difficult to sufficiently exhibit the anti-slip effect. When the elastomer is too soft, problems occur in strength and durability, and the magnetic force of the magnet body is increased, which is a problem in cost.

Alternatively, the pressing surface may be retracted in a range of more than 0.4 mm and less than 1 mm when the adsorption surface of the magnet body is forced to be adsorbed on the surface to be adsorbed. According to the experimental results of the test piece of the magnet structure performed by the inventors of the present invention, when the pressing surface satisfies the condition, the anti-slip effect is sufficiently exerted.

Further, when the adsorption surface is adsorbed on the adsorbed surface, the elastic system may have a thickness of 4% or more as compared with when the adsorbed surface is not adsorbed on the adsorbed surface. When the elastic body is thinned to the extent that the adsorption surface of the magnet body is adsorbed on the surface to be adsorbed, the anti-slip effect is sufficiently exhibited.

Alternatively, the elastic system may have a thickness of 8% or more as compared with when the adsorption surface is adsorbed on the surface to be adsorbed, when the adsorption surface is not adsorbed on the adsorption surface. In this way, the anti-slip effect is better achieved.

The elastic system is disposed in the vicinity of the magnet body, but the position thereof can be appropriately determined.

The elastic system may be disposed on the rear side of the magnet body in a sliding direction in a predetermined direction in which the magnet structure is slid in the adsorption surface. When the elastic body is disposed at this position, the anti-slip effect is favorably exhibited as compared with the case where the elastic body is disposed at another position.

Alternatively, the elastic system may be formed as a member having a length orthogonal to the sliding direction as a length in the longitudinal direction. In this way, it is easy to prevent the elastic body from being tilted in the paired sliding direction, and the anti-slip effect is easily obtained.

In the case where the elastic body includes the pressing surface, at least one groove may be provided on the pressing surface of the elastic body. By providing the groove on the pressing surface of the elastic body, the groove acts as a suction cup when the pressing surface of the elastic body is pressed by the suction surface, and the anti-slip effect is further exerted.

Alternatively, the groove may be orthogonal to the sliding direction described above, and in this manner, the anti-slip effect is more satisfactorily obtained. In other words, at least one groove may be provided in the pressing surface in a direction orthogonal to a sliding direction in a predetermined direction in which the magnet structure is slid in the adsorption surface.

Alternatively, the suction surface of the magnet body and the protruding portion of the elastic body may not overlap each other when viewed from the side of the adsorbed surface during use. Since the adsorption force of the magnet is proportional to the cube of the distance, even if the thickness is not thick, if the adsorption surface of the elastic body and the magnet body overlap, the adsorption of the magnet body against the adsorption surface becomes weak. According to the above configuration, since the adsorption surface of the magnet body is surely adsorbed to the surface to be adsorbed, the elastic body can be reliably pressed against the surface to be adsorbed. This causes the magnet structure that is forced to be adsorbed on the adsorbed surface to slide hard.

Further, the main body may be provided with a clip that can hold a predetermined object, a case that can accommodate a predetermined object, or a hook that can lock a predetermined object.

The magnet structure having the clip becomes a magnet clip. A magnet structure having a box is a so-called magnet case that allows a box containing a written or small object to be detachably attached to a surface to be adsorbed, and a magnet structure having a hook can be a hook-hanging dress or a pair of pictures. The adsorption surface is detachably attached to a so-called magnet hook that is forced to adsorb. Do not The use of the magnet structure of the present invention is not limited thereto.

Further, the magnet clip, the magnet hook, and the magnet case shown in each of the following embodiments are basically fixed to the surface to be adsorbed and fixed to be attached and detached from the following. However, the magnet structure, the magnet hook, and the magnet structure included in the magnet case described below may be fixed to the object to be adsorbed on the surface to be adsorbed other than the vertical surface, for example, the surface to be adsorbed from the user.

(First embodiment)

The magnet clip is described in the first embodiment. The magnet clip is detachably attached to the adsorbed surface which is a plane which can be adsorbed by the magnetic force, in a state in which the object to be clamped is held by the paper or the like. In the magnet holder of the present embodiment, the structure of the conventional magnet holder can be basically used.

Fig. 3 is an exploded perspective view of the magnet holder.

The magnet clip includes a base 100 and a handle 200. As will be described later, the base 100 holds the object between the object to be adsorbed and the handle 200.

In addition, the magnet clip of the present embodiment is made of a metal other than the magnet body and the elastic body to be described later.

The substrate 100 is composed of a metal plate. The substrate 100 includes a rectangular bottom plate 110. A fixing hole 111 is drilled in the center of the bottom plate 110 (Fig. 3). The fixing hole 111 is a circular hole and is threaded on the inner circumferential surface thereof. At the rear of the bottom plate 110, the first locking hole 112 (recessed portion) of the hole is drilled. The first locking hole 112 is a circular hole, but is not necessarily a circular hole.

On the left and right sides of the bottom plate 110, side panels 120 that are curved toward the bottom surface are connected. The height in the upper and lower directions in the first drawing of the side panels 120 is fixed in all of the front and rear directions. Behind the bottom plate 110, a back panel 130 that is curved toward the bottom surface is connected. The height in the upper and lower directions in the first figure of the back panel 130 is fixed in all of the left and right directions. Further, it is equal to the height in the upper and lower directions in the first drawing of the side panel 120.

On the side of the connection base plate 110 and the back surface plate 130, the second locking hole 131 (recessed portion) which is a hole is drilled so as to straddle the bottom plate 110 and the back surface plate 130.

On the bottom surface side of the bottom plate 110, a space surrounded by the bottom plate 110, the side panels 120, and the back panel 130 is formed. In addition, this space is a "hole" in the body of the present invention, and the first panel 120 and the back panel 130 are in the first diagram. The lower end is the "edge" of the hole. The side panels 120 corresponding to the edges of the pockets and the lower end of the first panel of the back panel 130 are joined together in a plane parallel to the bottom plate 110. This plane is in the virtual plane referred to in the present invention.

However, by providing the front panel having the same shape as the back panel 130 having the inner side surface along the front side of the magnet body 300 on the bottom plate 110, the above-mentioned "edge" can be formed into a ring shape.

On both sides in the width direction of the upper surface of the upper surface of the bottom plate 110, a support portion 113 which is formed by cutting one of the bottom plates 110 into a substantially U-shape and standing upright is provided, but is not limited thereto. The support portion 113 is for mounting the handle 200 to the base 100.

A support hole 113A that is not defined as a circular hole is provided in a portion on the upper side in the first figure of the support portion 113.

The magnet body 300 and the elastic body 400 are fixedly fitted in the above-described space formed on the bottom surface side of the bottom plate 110 corresponding to the hole referred to in the present invention.

The magnet body 300 is a magnet. The magnet body 300 is formed into a thin rectangular parallelepiped shape, in other words, a plate-like shape. The width of the magnet body 300 in the left-right direction is substantially equal to or smaller than the interval between the side panels 120. Further, the length of the magnet body 300 in the front-rear direction is slightly smaller than the length of the bottom plate 110 in the front-rear direction. Further, the thickness of the magnet body 300 in the vertical direction in the first drawing is equal to the height in the upper and lower directions in the first drawing of the side panel 120 and the back panel 130. The plane on the lower side in the first drawing of the magnet body 300 is the adsorption surface referred to in the present invention which is intended to be fixed to the surface to be adsorbed.

In the vicinity of the center of the magnet body 300, a magnet hole 320 having a circular through-hole is drilled (Fig. 3). The magnet hole 320 is disposed and fixed to the bottom plate 110 The position corresponding to the hole 111 is used. The magnet body 300 is screwed and locked by the front end of the screw 330 (Fig. 3) having the same diameter as the magnet hole 320 penetrating the magnet hole 320, and the head portion 331 and the bottom plate 110 of the screw 330 are screwed together. The space is clamped, whereby it is fixedly mounted to the bottom plate 110. Further, since the fixed range of the adsorption face 310 side of the magnet hole 320 is such that the diameter is made large enough to accommodate the head 331 of the screw 330, the head 331 of the screw 330 is not lower than the lower side of FIG. The adsorption surface 310 is more prominent.

Further, the method of fixing the magnet body 300 of the bottom plate 110 is not limited thereto. For example, the magnet body 300 can be fixed to the bottom plate 110 by adhesion.

The magnet body 300 attached to the bottom plate 110 is in a state in which both ends in the width direction of the left and right sides are substantially in contact with the inner side surfaces of the side panels 120, and a gap is formed between the back surface and the back surface plate 130. status.

The adsorption surface 310 of the magnet body 300 fixed to the bottom plate 110 is in a state of being aligned with the above-described virtual surface. However, the adsorption surface 310 may not coincide with the virtual surface, and may be slightly indented (for example, about 0.5 mm, more specifically, about 0.2 mm to 0.7 mm) on the rear side of the virtual surface (upper side in FIG. 1).

The elastomer 400 has elasticity. As will be described later, when the adsorption surface 310 of the magnet body 300 is forced to be adsorbed on the surface to be adsorbed, the portion of the elastic body 400 that protrudes from the virtual surface of the elastic body 400 is crushed by the adsorption surface. Preferably, the elasticity of the elastic body 400 is such that when the adsorption surface 310 of the magnet body 300 is forced to be adsorbed on the surface to be adsorbed, the pressing surface which is located later from the virtual surface becomes the same surface as the virtual surface. The elastomer 400 is composed of a material having elasticity or a sponge shape. In the case where the elastomer 400 is composed of a material having elasticity, the material thereof is, for example, natural or synthetic. Can also be rubber or PVC Other resins, such as enamel. The same is true for the case where the elastomer is sponge-like.

The elasticity of the elastomer 400 may, for example, also have a modulus of elasticity in the range of less than 40 MPa. Further, in the case where the elastic body is rubber, the hardness may be smaller than Hs70. In the present embodiment, the elastic system is not limited thereto, and the elastic system is made of rubber and has a hardness of about Hs of 40 degrees.

The elastic body 400 has a substantially rectangular parallelepiped shape and is formed in a shape elongated in the left-right direction. The width of the elastic body 400 in the left-right direction is substantially equal to or slightly smaller than the interval between the side panels 120. Further, the length of the elastic body 400 in the front-rear direction is equal to the length of the rear direction before the gap formed between the back surface of the magnet body 300 and the back surface plate 130 which is formed when the magnet body 300 is attached to the bottom plate 110. Or slightly smaller than it.

The elastic body 400 includes three first locking convex portions 410 (third drawing) which are cylindrical convex portions on the front side of the upper surface in the first drawing, and includes a rectangular parallelepiped convex portion on the rear side of the surface. The two second locking protrusions 420. The shape, size, and position of the first locking convex portion 410 are formed in accordance with the shape, size, and position of the first locking hole 112 provided in the bottom plate 110, and the shape and size of the second locking convex portion 420 and The position is made to correspond to the shape, size, and position of the second locking hole 131. In the elastic body 400, the three first locking projections 410 are inserted into the three first locking holes 112 at the three corresponding positions, and the two locking projections are provided. Each of the 420 is inserted into the two second locking holes 131 at the positions corresponding to the two, and is locked to the bottom plate 110.

In a state of being fixed to the bottom plate 110, the elastic body 400 is made to have both sides The surface is along the inner side surface of the side panel 120, and the front surface thereof is along the back surface of the magnet body 300, and the back surface is along the back surface plate 130. That is, the elastic body 400 is the gap formed by the both side panels 120 which is formed between the back surface of the magnet body 300 and the back surface plate 130. In this state, the portion of the elastic body 400 that protrudes from the above-described virtual surface (the protruding portion of the elastic body 400 referred to in the present invention) is a case where the magnet holder is viewed from the suction surface when it is used, and the magnet body 300 The adsorption faces 310 do not overlap. Further, the elastic body 400 is a case where the magnet clip is viewed from the suction surface when it is used, and does not overlap the magnet body 300.

Further, the fixing method of the elastic body 400 of the bottom plate 110 is not limited thereto. For example, the elastic body 400 can be fixed to the bottom plate 110 by adhesion. Further, the order in which the elastic body 400 and the magnet body 300 of the bottom plate 110 are mounted is in any order. Further, the elastic body 400 may be indirectly fixed to the bottom plate 110 by being fixed to the magnet body 300, for example.

The lower portion of the elastic body 400 in the first drawing is in a state in which the elastic body 400 is attached to the bottom plate 110, and is the above-mentioned "hole" from the space surrounded by the bottom plate 110, the side panels 120, and the back panel 130. "Exposed state." This portion is a projection referred to in the present invention, and the lower surface in the first drawing is the pressing surface 430 referred to in the present invention.

The protruding portion of the elastic body 400 is a portion of the elastic body 400 that protrudes from the adsorption surface 310 of the magnet body 300, in other words, a portion that is crushed when the adsorption surface 310 is forced to be adsorbed on the adsorption surface. That is, as long as the adsorption surface 310 is located on the rear side of the virtual surface, the portion of the elastic body 400 that is further forward than the virtual surface becomes a protruding portion.

The protrusion of the elastomer 400 is above and below the first figure of the elastomer 400 The direction is defined as the thickness, and is not necessarily limited to such a case that it accounts for 4% or more of the entire thickness of the elastic body 400, and preferably 8% or more. Further, the thickness of the protruding portion of the elastic body 400 is more than 0.2 mm, preferably more than 0.2 mm and less than 2 mm. The thickness of the protrusions is more preferably greater than 0.4 mm and less than 1 mm.

The pressing surface 430 is provided with grooves 431 (Fig. 1(c), Figs. 2(b-1) to (b-3)) which are transverse to the left and right width directions. The groove 431 is plural, and is not necessarily limited to this, and is two in the present embodiment.

The handle 200 is attached to the above-described support portion 113 of the base 100.

The handle 200 includes a handle plate 210 that is a plate that is gently curved toward its front-rear direction. On both sides in the width direction of the handle plate 210, the support plate 220 for the plate for mounting the support portion 113 is attached so as to extend downward in the first drawing. The interval between the inner side faces of the two support plates 220 is slightly larger than the interval between the outer sides of the two support portions 113.

In the two support plates 220, a handle hole 221 which is a circular hole is provided, but is not limited to a circular hole.

The handle 200 is attached to the bottom plate 110 by using a rod 500 which is a rod-shaped body as shown in Fig. 3 . The shaft 500 includes a cylindrical rod 510, a head portion 520 on the proximal end side thereof, and a screw portion 530 which is threaded on the outer peripheral surface thereof to be thinner than the rod body 510 on the front end side thereof.

In order to attach the handle 200 to the base 100, the inner side faces of the two support plates 220 are brought into contact with the outer side faces of the two support portions 113, so that the two support plates 220 are spanned by the two support plates 220. At this time, in the supporting portion 113 and the supporting plate 220, the supporting hole 113A drilled in the supporting portion 113 and the supporting plate are The positions of the handle holes 221 drilled by 220 are the same. In this state, the shaft hole 500 is inserted through the handle hole 221 on the front side in the third drawing in the order of the handle hole 221, the support hole 113A, the support hole 113A, and the handle hole 221 in this order. The screw portion 530 at the front end of the shaft bar 500 has a shaft portion 610 which is a hole 611 in which the inner peripheral surface is machined with a thread groove, and a cap screw 600 having a head portion 620 is formed so that the screw portion 530 penetrates the hole 611. The state is screwed. Thereby, the two support plates 220 of the handle 200 are attached to the base 100 in a state in which the head 520 of the shaft 500 and the head 620 of the cap screw 600 are caulked from both sides.

In this state, the handle 200 is rotatable about the shaft 500.

Further, when the base 100 and the handle 200 are connected by the shaft 500, the shaft 500 is passed through the torsion spring 700. The torsion spring 700 has a first end portion 710 on one end side abutting on a surface on the upper side in the first drawing of the bottom plate 110, and a second end portion 720 on the other end side and a lower side in the first drawing of the handle plate 210. The face is abutted (Fig. 2 (b-1)). Further, when the angle of the narrow side between the first end portion 710 and the second end portion 720 is twisted and narrowed from the state shown in FIG. 2(b-1), the torsion spring 700 is to be restored. The force acting in the state shown in Fig. 2 (b-1). Therefore, the handle 200 is rotated by the rotation of the shaft bar 500 so that the rear end of the handle plate 210 approaches the base 100 by applying a force against the elastic force from the torsion spring 700 to the rear end of the handle plate 210, but When the force is removed, the state shown in Fig. 2 (b-1) is restored by the elastic force from the torsion spring 700.

That is, the handle 200 has a state in which the edge on the front side of the handle plate 210 abuts against the bottom plate 110 of the base 100 as a starting position, and also applies a force to the rear end of the handle plate 210, whereby the handle plate 210 is The rear end is adjacent to the bottom plate 110 such that the edge of the front side of the handle plate 210 is away from the bottom plate 110 and is rotatable about the shaft rod 500. Further, the handle 200 is returned to the home position by the elastic force from the torsion spring 700, when the above-described force applied to rotate the handle 200 is removed.

Next, the method and operation of the magnet clip will be described.

In the case of using a magnet clip, first, an object is sandwiched between the bottom plate 110 of the base 100 and the handle plate 210 of the handle 200. For this reason, in the present embodiment, it is assumed that the object is a plurality of sheets of paper that are overlapped. In order to hold the paper with the magnet clip, the handle 200 is rotated about the shaft 500 by applying a force to the rear end of the handle plate 210, whereby the edge of the front side of the handle plate 210 is moved away from the bottom plate 110, and the object is inserted. The gap between the handle plate 210 and the bottom plate 110 is opened. Next, the force applied to the handle plate 210 is removed, and the force from the torsion spring 700 is used to return to the initial position of the state in which the edge of the front side of the handle plate 210 abuts against the bottom plate 110 of the base 100. On the handle 200. Thereby, the object is held between the bottom plate 110 of the base 100 and the handle plate 210 of the handle 200.

Then, the magnet clip that sandwiches the object between the bottom plate 110 and the handle plate 210 is close to the suction surface X as shown in Fig. 4(a). Further, in Fig. 4(a), only the base 100 of the magnet holder, the magnet body 300, and the elastic body 400 are shown, and the illustration of the handle 200 is omitted. Further, in Fig. 4(a), the adsorption surface 310 of the one magnet body 300 is held parallel to the surface to be adsorbed X, and the magnet clip is brought close to the adsorption surface X. However, it is not necessary to keep the magnet clip close to the adsorption surface X. The adsorption surface 310 is parallel to the adsorbed surface X.

In a state in which the adsorption surface 310 of the magnet body 300 is forced to be adsorbed on the surface to be adsorbed X, as shown in FIG. 4, if the adsorption surface 310 is kept parallel to the surface to be adsorbed X, the pressing surface 430 of the elastic body 400 is assumed. Is located in the suction of the magnet body 300 The attachment surface 310 is closer to the side of the adsorbed surface X and has a step L between it and the adsorption surface 310.

Then, when the adsorption surface 310 of the magnet body 300 is adsorbed on the surface to be adsorbed X, as shown in Fig. 4(b), the elastic body 400 is crushed between the substrate 100 and the surface to be adsorbed X, and the pressing surface thereof is pressed. The 430 system is in fact in the same plane as the adsorption surface 310 of the magnet body 300.

As shown in Fig. 5, the magnet clip system is such that the front side of the base 100 and the handle 200 face downward and is forced to be adsorbed on the adsorbed surface X. Therefore, generally, with gravity, the downward force in Fig. 5 acts on the magnet clip and the object Y to be held. That is, the magnet clip is slid in the downward direction in the fifth drawing. When the direction is defined as the sliding direction, the elastic body 400 is placed on the rear side in the sliding direction when the adsorption surface 310 of the magnet body 300 is attracted to the adsorption surface X as shown in FIG. 4 . Moreover, the pressing surface 430 of the elastic body 400 is provided so that the groove 431 along the longitudinal direction of the pressing surface 430 is in a state of being orthogonal to the sliding direction.

At this time, for example, a downward force acts on the magnet clip, and between the adsorption surface 310 of the magnet body 300 and the adsorbed surface X, an adhesion friction force is generated in a direction opposite to the direction in which the force acts, and at the same time in the elastic body 400. The pressing surface 430 and the surface to be adsorbed X generate an adhesion friction force, a deformation loss friction force, and an excavation friction force in a direction opposite to the direction in which the force acts.

Thereby, the magnet clip is surely fixed to the pressing surface 430, and for example, it is difficult to slide downward.

Further, since the elastic body 400 is relatively downward-facing, it is located on the rear side of the magnet body 300, and is longer in the direction orthogonal to the downward force, so that it falls on the right or left side of the magnet clip, such as the elastic body 400. Rotation is also hard to happen.

[Experimental example]

In the case of changing the step L in FIG. 4 (however, in this case, L is not the distance from the adsorption surface 310 to the pressing surface 430, but the distance from the virtual surface to the pressing surface 430), a plurality of tests are performed. The magnet clip described is an experiment in which the magnet clip to be tested is adsorbed on the surface to be adsorbed, and each of the hard slidability is performed.

The adsorption surface 310 of the magnet body of the magnet clip to be tested is located rearward of the virtual surface by 0.3 mm. The material of the elastomer used in the magnet clips tested was the same, and it was an amine formate rubber having a modulus of elasticity of about 8.9 MPa and a hardness of about Hs40. Further, the portion of each of the elastic bodies 400 located on the rear side of the virtual surface, in other words, the portion hidden in the "hole" referred to in the present invention has a thickness of 4.3 mm.

The test of the difficulty of sliding the magnet clip is to vertically arrange the surface of the coated iron plate (one part of the book holder) as the adsorbed surface X, and at the same time, the magnet clip is adsorbed on the adsorbed surface X, and is forced to be adsorbed on The magnet clip of the suction surface X is applied by applying a force in the sliding direction described with reference to Fig. 5 by slightly sliding the magnet clip from the stationary state on the adsorbed surface X. Recorded is the position of the magnet clip after the magnet clip has been slid from a stationary state, and the force applied to the magnet clip at that position (the force required to continuously move the magnet clip).

The position of the above-mentioned magnet holder and the recording of the force applied to the magnet holder were carried out using SHIMADZU AGS-J (trademark) of a tabletop precision universal testing machine sold by Shimadzu Corporation.

The results of the experiment are shown in the first to eleventh tables from Fig. 6 to Fig. 8. The stroke of the horizontal axis in each table indicates the distance from the predetermined reference point to the sliding direction of the magnet clip, and the force of the vertical axis in each table indicates that the magnet clip is located at the position The force applied to the magnet clip.

The magnet clip of the experimental result shown in the first table is the above-described step L=0 mm, and the magnet clip of the experimental result shown in the second table is the above-described step L=0.2 mm. Hereinafter, in the magnet clip after the magnet clip of the experimental result shown in the third table, the step is increased by 0.2 mm steps, and the magnet clip of the experimental result shown in the eleventh table is the step L = 2 mm.

As a result of the experiment in the first table, the magnet clip starts to move when a force of about 8.7 N is applied (the portion where the stroke is almost constant at about 6 mm, the test force rises substantially vertically, the magnet clip does not move, and then, in the graph The state magnet moves in a substantially horizontal movement.) The maximum test force required to keep the magnet clamp moving continues is also 8.7N. At this time, the elastic body 400 is not compressed because the magnet body 300 of the magnet clip is forced to be adsorbed on the surface to be adsorbed, so the thickness thereof is not reduced.

Similarly, the magnet clip with a step difference of L = 0.2 mm starts to move when a force of about 9 N is applied (the portion where the stroke is almost constant at about 6 mm, the test force rises substantially vertically, the magnet clip does not move, and then, in the graph The state magnet moves substantially horizontally. (), the maximum load required to keep the magnet clamp moving continues is 9.1N.

Similarly, a magnet clip with a step difference of L = 0.4 mm starts to move when a force of about 9 N is applied, and the maximum load required to keep the magnet clip still moving is 15.4 N.

In this way, the magnet clamps with a step difference of L = 2 mm are sequentially investigated for the maximum test force.

The results are summarized in Tables 12 and 13 shown in Figure 9.

Table 12 shows the test results of the experimental results shown in Tables 1 to 11 as Test 1 to Test 11, indicating the maximum test force (= and magnetic force) obtained in each test. The value of the friction between the magnet clip and the adsorbed surface X is proportional to the adsorption force of the iron clip to the adsorbed surface X. The thirteenth table is the one that graphically shows the contents of the 12th table.

In addition, in the case of the magnet holder, when the adsorption surface of the magnet body is adsorbed on the surface to be adsorbed, the thickness of the elastic body is reduced by a few percent from the original thickness as the compression ratio. For example, since the elastomer 400 in the magnet clip of L = 0.2 mm has an original thickness of 4.3 mm (thickness hidden in the hole) + 0.2 mm (thickness of the amount of the step L) = 4.5 mm, which is flattened and thinned. The thickness of the step is a thickness of 0.2 mm, so the thickness is reduced by 0.2 mm ÷ 4.5 mm × 100 = 4.4%. Similarly, the elastomer 400 in the magnet clip of L = 0.4 mm was only thinned by 0.4 mm 0.4 (0.4 mm + 4.3 mm) × 100 = 8.5%. The same calculation is performed for the other magnet clips, and the compression ratio is obtained.

It is known from the 12th table and the 13th table that the maximum test force when the step L=0 mm is greater than the step difference L=0.2 mm (compression ratio 4.4%), the maximum test force becomes meaningfully small. The difference is more remarkable when it is larger than the step difference L = 0.4 mm (the compression ratio is 8.5%), and gradually becomes smaller from the time point of the step difference L = 0.8 mm (compression ratio = 16%), but even if the step is L = 2 mm ( The compression ratio is 32%), and the maximum test force becomes more significant than the step difference L = 0 mm, and is still larger than the step L = 0.2 mm (compression ratio 4.4%).

In particular, in the range from the step difference L = 0.4 mm (the compression ratio is 8.5%) to the step L = 1 mm (the compression ratio is 19%), the maximum test force becomes considerably larger than the case where the step L = 0 mm. This means that as long as the step is in that range, the magnet clip is extremely difficult to slide against the adsorbed surface X.
