Description

  The present invention relates to a clip for sandwiching, for example, a sandwiched body using a magnet.

In recent years, various products using magnetic force and magnets have been developed. The magnetic force is used, for example, in motors, solenoid valves, health appliances, and the like, and is also used in the medical field, educational field, and transportation means, and its use is expected to expand further in the future.

On the other hand, Non-Patent Document 1 describes an example of a magnetic adsorption paper holder. Normally, since the magnetic force works only in one direction of adsorption or repulsion, the bent portion has a repulsive force to maintain an open state. However, since resin is used, it is easy to deteriorate with respect to heat, the shape is not simple, and thickness is required.
Japanese Utility Model Publication No. 63-189678

In the prior art, the magnetic clip is used only by the method of holding the object to be held. When one of the holding pieces is pressed and spread to remove the already held object, the holding piece is closed immediately when the finger is released.
However, in many cases, it is more convenient to keep it open until it is held once. Until now, new components had to be added in order to have both the pinching function and the function of maintaining the open state.
In view of the above situation, there is provided a configuration of a magnet that is held only by using a magnet and is kept open by a repulsive force when separated by a predetermined interval.

In order to solve the above problems, the present invention provides the following configurations.
The invention according to claim 1 is a lower base, a first magnet having a through-hole disposed in the lower base and penetrating in a thickness direction, an upper base continuously connected to the lower base, A first magnet and a second magnet disposed with the magnetic poles oriented in the same direction on the upper base, wherein the lower base or the upper base is bent so as to be elastically returnable, and the first magnet and the second magnet A repulsive force acts when the magnet approaches the magnetic force acting range, and further, when the force is applied and bent, the acting direction of the magnetic force is reversed and the attracting force acts, and the space between the lower base and the upper base Further, the present invention provides a clip characterized in that the clipped body can be clipped.

The invention according to claim 2 provides the clip according to claim 1, wherein the clip is separated from the bent portions of the lower base and the upper base, and is connected by a method having a joint structure. is there.

According to the first aspect of the present invention, the ring-shaped first magnet is fixed to the lower base, and the second magnet having the magnetic poles oriented in the same direction is disposed on the upper base, The repulsive force works when the bending magnetic force approaches the range of action of bending magnetic force, but when applied and bent together, the action of magnetic force reverses and the object to be clamped can be clipped between the lower base and the upper base. . Further, it is possible to provide a clip in which one base is pushed and expanded from a closed form, and is kept open by the repulsive force after being separated to some extent.

According to invention of Claim 2 of this invention, the clip which joined the bending part of the lower base and the upper base with the joint structure, and was able to rotate a predetermined range can be provided.

The best mode for carrying out the present invention (hereinafter referred to as “the present embodiment”) will be described with reference to the drawings.
In addition, the same number is attached | subjected to the component which carries out the same function as the component used in embodiment demonstrated sequentially from FIG.1 and this embodiment (1), and description is abbreviate | omitted as much as possible.
Further, in this embodiment, the shape of each magnet is circular or ring-shaped, but since many variations are conceivable, details of the shape will be described last with reference to the drawings.

Here, before entering into the description of the present embodiment, the relative relationship between the first magnet and the second magnet will be described first to make the embodiments described later easier to understand. Needless to say, the clamping function can be used other than the clip.

FIG. 1 (9 a) is a diagram showing the relative relationship between the first magnet 1 and the second magnet 2, and the magnetic poles are respectively directed in the thickness direction of the magnet, and the N pole (hereinafter, N) to the S pole (hereinafter, “ Magnetic field lines appear in S). In the case of (9a), the surface on which the first magnet 1 and the second magnet 2 face each other is SS, and the repulsive force (the direction of the up and down arrows) is working.

However, in FIG. 1 (9b), it was formed independently when it was made to approach 4-6 mm (which varies further depending on the size, shape, strength of magnetic force, etc.) against the repulsive force. It seems that the magnetic field flow changes to a combined magnetic field flow.
From that moment, the direction of the force is reversed between the first magnet 1 and the second magnet 2 to the attractive force (the direction of the up and down arrows).
That is, in the vicinity of the through hole 3, the flow of the magnetic field in the through hole 3 is reconstructed from N of the first magnet 1 to S of the second magnet 2 and from N of the second magnet 2 to S of the first magnet 1. It seems to be that.

FIG. 1 (9 c) shows a form in which the second magnet 2 is sucked and held in the through hole 3 of the first magnet 1, but both magnets are stable in the form (9 c). At this time, even if a force is applied to the second magnet 2 and moved in the vertical direction, it returns to the original position within a predetermined range with an attractive force. The shape of the through hole 3 and the shape of the second magnet 2 are symmetric with respect to the thickness direction (they function even if they are not symmetric), and the balance of magnetic force is better.
The size of the second magnet 2 functions as long as it is approximately the same size as the through-hole 3 or passes through the through-hole 3, but the adsorption action becomes gradually weaker as the size becomes larger than the through-hole 3, and eventually the adsorption is stopped.
One set of the first magnet 1 and the second magnet 2 described in (9a), (9b), and (9c) is referred to as a clip set 9.

FIG. 2 is a perspective view of the clip of the present embodiment (1). The lower base 4 and the upper base 5 can be made of a solid such as resin, metal, mineral, or wood. The thickness of the bent portion 6 is adjusted to make it moderately elastic, etc., but the thickness is adjusted. However, the elasticity is not necessary to maintain the open state. Use to maintain.

In this method, the first and second magnets are attached. The first and second magnets are directly adhered to the surface with an adhesive, or are cut into the shape of the magnet and fitted into the base so that the magnetic force is easily fixed and used. In addition, there is a method in which the surface is covered with various members so that the magnet is not seen and used.
On the other hand, the clip function can be used as a page marker such as a book, a file, a bookmark, or a storage case opening / closing device, or simply as a spring.

FIG. 3 is a perspective view of the clip of the present embodiment (1) in which the base is bent into a “<” shape, but it is often easier to manufacture by making the bent shape from the beginning into a fixed shape. . When the lower base 4 is used by adsorbing it to the adsorbable wall, when the clip is opened from the closed form, the elasticity of the bent portion 6 is that the upper base 5 jumps up too much and adsorbs to the adsorbable wall on the back. Can be prevented by sex. Reference numeral 7 denotes a sandwiched body (hereinafter referred to as a paper piece).

Next, regarding the positional relationship between the two magnets, when the second magnet 2 of the upper base 5 is bent together, the second magnet 2 is adjusted and adhered so as to be approximately at the center of the through hole 3 of the first magnet 1. Thereby, a repulsive force (SS in FIG. 3) acts between the first magnet 1 and the second magnet 2 at a predetermined distance, and the elasticity of the bent portion 6 and the weight of the upper base 5 are balanced. The upper base 5 is maintained at a balanced position. If the paper piece 7 etc. are arrange | positioned in this form and a base is applied and closed by this form, adsorption | suction will work and it can clip.

Again, the base is pressed and spread, and when it is spaced apart by a predetermined distance, it returns to the open state due to the repulsive force of the first magnet 1 and the second magnet 2, and is convenient for the next clip. There is also a method in which an adhesive or the like is attached to the back surface of the lower base 4 so that it can be attached to a nonmagnetic wall.

FIG. 4 is a clip perspective view of the embodiment (2) in a form using a joint structure. The joint structure 8 includes a core body 8a and a cover body 8b, and is configured so that the joint portion can rotate within a predetermined range. The joint structure 8 does not need elasticity, and uses the action of adsorption and repulsive force of only a magnet. Switch.

FIG. 5 is a perspective view of the embodiment (3) in which the clip is used as a clipboard, and the lower base 4 is used as a clipboard by expanding the lower base 4.

FIG. 6 is a perspective view of the clip in the form (4) in which the base is bent into a “<” shape. In this case, it is conceivable that a piece of paper or the like is not sandwiched between the magnet portions in order to obtain a more effective effect of the magnets. However, the stopper 10 has a prevention function for that purpose (it functions even without it), and the opening 11 The stopper 10 is provided to prevent the stopper 10 from colliding with the upper base 5, but there is a method in which the shape of the base is deformed and used.
The first magnet 1 is embedded in and bonded to the inside of the base and the inside is formed as a cavity 11, and the second magnet 2 is bonded to the surface of the upper base 5 and can enter the cavity 11. When sandwiched between both magnets, one magnet cannot enter into the cavity 11 part, but when sandwiched between the bases, the movable range is increased and the number of sheets of paper that can be sandwiched is of course. I will be worried.

FIG. 7 is a perspective view of the clipboard of the present embodiment (5). A stopper 10 is attached to the lower base 4 or the base is deformed so that the clamped body 7 is not pinched by the clip set 9.

FIG. 8 is a perspective view of a clip file according to the present embodiment (6). The door 15 is attached to the side of the base and is used as a file by folding it in half.

FIG. 9 shows a storage case of the present embodiment (7) using a clip for opening and closing. By providing a cavity 12 on one base, it is used as a storage case. In a normal magnet configuration, the door 15 closes immediately even if it is opened. However, in this embodiment, the door 15 can be kept open. However, there is also a method of using the bent portion 6 with elasticity by the weight of the door 15.

Finally, the shape of the magnet will be described.
The first magnet 1 and the second magnet 2 described so far are both formed in a circular shape or a ring shape. However, as long as the effects of the present invention are achieved, the first magnet 1 and the second magnet 2 may have other shapes such as a square shape and other shapes. There may be.

In FIG. 10 (16), the first magnet 1 represented by black N (14) is fixed to the lower base 4, and the second magnet 2 represented by white S (15) is fixed to the upper base 5. For example, in addition to the basic shape (16), a ring shape with a part cut out (17), a shape in which the ring shape is divided in half (18), and a shape arranged in a mosaic shape (20) are also present. It is included in the technical idea of the invention. Furthermore, as indicated by (19), each of the magnets can be constituted by a plurality (three in the example) of magnet pieces arranged in a direction intersecting the clamping direction. That is, by arranging the peripheral portion of the first magnet 1 and the peripheral portion of the second magnet 2 close to each other, the adsorption and repulsion are switched to exhibit a magnetic force that can withstand use. At this time, it goes without saying that each of the magnet pieces has the same magnetic pole direction and is fixed to the same base.
Although the illustration is omitted, even in the second magnet 2, even if it is divided and deformed into small pieces like the first magnet 1, the magnetic pole directions are the same and they are fixed to the same base, and the other magnet peripheral portion is attached. If so, the function is the same.

In addition, the combination of the lower base 4, the upper base 5, the first magnet 1, and the second magnet 2 is not limited to the embodiment and can be used interchangeably. There is no problem even if the number and position of the clip sets 9 are appropriately changed and used.
In some cases, the magnet is buried in the base, or the shape of the base is deformed by raising or sinking, and the position of the magnet is moved for use.
