JP 2000-62372 A

  The device described in Patent Document 1 is configured to hold a sheet member by attaching and detaching a magnet to and from a magnetic surface. That is, the magnet holder described in Patent Document 1 can sandwich the sheet member by cooperating with a magnetic surface (wall surface) of a bulletin board, a partition, steel furniture, a refrigerator, etc., and has no magnetic surface. In the state, the sheet member could not be clamped. Further, at the moment when the magnet body is separated from the magnetic surface, the magnet holder itself may be separated from the magnetic surface.

On the other hand, by preparing two magnet holders described in Patent Document 1 and configuring the polarity of the magnet body so that both magnets adsorb each other, the sheet member can be sandwiched even without a magnetic surface. it can. At this time, it is possible to attach and detach the sheet member by separating the magnet bodies from each other by overlapping the plate bodies having tapered surfaces in the same manner as described above and creating a gap there between. However, the magnet holders may be separated at the moment when the magnet bodies are separated.
An object of the present invention is to provide a clamping device configured such that a magnetic member is separated from a magnetic material surface to attach and detach a sheet member, and the clamping device main body is not separated from the magnetic material surface at that time. To do.
The present invention provides a holding device configured to attach and detach a sheet member by separating magnet bodies provided so as to attract each other, and the main bodies of the holding device are not separated at that time. The purpose is to provide.

The first feature of the clamping device according to the present invention is that it includes at least two tapered flat portions on which one surface side of the flat plate-like main body decreases in thickness from the vicinity of the center toward the periphery thereof, The magnet body is provided in each of the flat portions.
The main body shape of the clamping device is a flat plate shape. When one surface of the main body, that is, the bottom surface portion comes into contact with a flat surface, two or more tapered flat surface portions are provided so that the gap gradually increases between the surface and the contact surface. When there are two plane portions, the main body shape is rectangular, and when there are three or more plane portions, the main body shape is triangular or circular. A magnet body is provided on each flat portion of such a body-shaped clamping device. For example, when the main body shape is rectangular, since the magnet body is provided on the two plane portions, the other magnet body is attracted to the magnetic body surface at the moment when one magnet body is separated from the magnetic body surface. The clamping device itself does not fall off the magnetic surface. Moreover, even when two such clamping devices are prepared and the sheet member is clamped so that both magnet bodies stick to each other, the other magnet bodies stick to each other at the moment when one magnet body is separated. As a result, the holding devices are not separated from each other. This is the same even when there are three or more plane portions.

According to a second feature of the clamping device of the present invention, in the clamping device according to the first feature, there are four plane portions, and one magnet body is provided in each of the plane portions, and is point-symmetric. The polarities of the magnets at the same position are the same, and the polarities of the adjacent magnet bodies are different.
As described above, the body shape of the clamping device may be various shapes such as a rectangular shape, a circular shape, and a triangular shape as long as it is a flat plate shape. In this case, when there are four plane portions and a magnet body is provided on each plane portion, the magnet bodies at point-symmetrical positions have the same polarity, and adjacent magnet bodies have different polarities. This makes it possible to use both magnet bodies so as to attract each other only by combining two exactly the same clamping devices. Moreover, even if a rotational stress is applied around the attracting portion in a state where the magnet bodies are attracted to each other, there is an effect that the sandwiching devices are difficult to rotate due to repulsion between the adjacent magnet bodies.

A third feature of the clamping device of the present invention is that in the clamping device according to the first or second feature, an anti-slip member is provided on the other surface side of the main body.
When the holding device main body is made of a material such as plastic, the surface on which the magnet body does not exist may be in direct contact with the magnetic surface. In such a case, since the magnet body does not directly contact the magnetic body surface, the upper surface of the clamping device becomes slippery with respect to the magnetic body surface and may fall due to its own weight. Therefore, by providing an anti-slip member such as rubber, rubber, gel, hook-and-loop fastener, urethane, foaming, sucker, etc. on the upper surface side of the main body of the holding device, the holding device is caused by friction between the magnetic surface and the anti-slip member. It can prevent itself falling by its own weight.

A fourth feature of the clamping device according to the present invention is that two clamping devices according to the first, second, or third features are prepared, and the magnet bodies are attracted to each other so that the planar portions coincide with each other. is there.
This means that by combining two clamping devices and using both magnet bodies so as to attract each other, the sheet member can be clamped or clothing items such as clothespins can be clamped. It is something that can be done.

A fifth feature of the sandwiching device of the present invention is that in the sandwiching device according to the first, second, third, or fourth feature, two or more magnet bodies are provided on the planar portion.
This is because, when two clamping devices are combined and used so that both magnet bodies are attracted to each other, since two or more magnet bodies are attracted to each other, even if rotational stress is applied, the clamping device It is designed to make it difficult for each other to rotate.

  According to the present invention, the sheet member is attached and detached by separating the magnetic body from the magnetic surface, and the holding device body does not fall off from the magnetic surface at that time. Further, according to the present invention, the magnetic members provided so as to be attracted to each other are separated from each other, so that the sheet member is attached and detached, and the main bodies of the clamping device are not separated at that time.

  Preferred embodiments of a clamping device according to the present invention will be described below with reference to the accompanying drawings. In this embodiment, a circular clip will be described as an example of the clamping device.

The magnet bodies 11 to 14 are embedded in a cylindrical hole provided in the main body of the clip 10 and are fixedly bonded thereto. The upper surface 1A of the clip 10 is formed from a part of a spherical surface. The bottom surface of the clip 10 has four flat portions 15 to 18 each having a fan shape formed so that the four magnet bodies 11 to 14 are embedded therein. A rectangular bottom surface portion 19 is provided so as to be surrounded by the fan-shaped flat portions 15 to 18. As shown in FIGS. 1 (A) and 1 (B), when the bottom surface portion 19 comes into contact with a flat surface, the flat portions 15 to 18 gradually increase in gap with the contact surface. A tapered surface is formed. That is, the tapered flat portions 15 to 18 are configured such that the plate thickness decreases from the vicinity of the center of one surface of the main body of the flat clip 10 toward the periphery thereof. The magnet bodies 11 to 14 are embedded in the main body of the clip 10 so that the tapered surface and the bottom surfaces of the magnet bodies 11 to 14 coincide with each other.

  FIG. 2 is a view showing a state in which the clip 10 of FIG. 1 is adsorbed on a magnetic surface (wall surface) of a bulletin board, a partition, steel furniture, a refrigerator, or the like. As is apparent from the figure, the clip 10 is configured such that only one of the flat portions 15 to 18 is in contact with the magnetic surface 20. Accordingly, only one of the magnet bodies 11 to 14 is attracted to the magnetic surface 20. 2A shows a state where the magnet body 14 is attracted to the magnetic surface, and FIG. 2B shows a state where the small magnet body 12 opposite to the magnet body 14 is attracted to the magnetic surface 20. Indicates the state. In the state shown in FIG. 2B, a sheet member (a thin object within a range in which a magnet can be adsorbed such as a memo paper, a document, a photograph, glass, or cloth) in a gap between the lower side of the clip 10 and the magnetic surface 20. 22 is inserted, and the vicinity of the magnet body 14 on the upper surface 1A side of the clip 10 is pressed against the magnetic body surface 20 side, so that the magnet body 14 is attracted to the magnetic body surface 20 and the sheet member 22 can be held by the clip 10. become.

  FIG. 3 is a combination of two clips shown in FIG. 1 to sandwich sheet-like memo paper, documents, photographs, etc., and to sandwich clothes, bath towels, sheets, and the like. In the clip 10 of FIG. 1, the bottom surfaces of the magnet bodies 11 and 13 are N poles to form flat portions 15 and 17, and the bottom surfaces of the magnet bodies 12 and 14 are S poles to form flat portions 16 and 18. . When two clips 10a and 10b configured as described above are prepared and the magnet bodies are attracted to each other, as shown in FIG. 3, the magnet body 14a (S pole) of the clip 10a and the magnet body 13b of the clip 10b ( As a result, the large gap portion is formed between the magnet body 12a and the magnet body 11b as shown in FIG. By sandwiching a sheet member or the like into the gap and pressing the vicinity of the magnet bodies 12a and 11b on the upper surface 1A side of the clips 10a and 10b from both sides, the magnet body 14a (S pole) of the clip 10a as shown in FIG. ) And the magnet body 13b (N pole) of the clip 10b are separated, and conversely, the magnet body 12a (S pole) of the clip 10a and the magnet body 11b (N pole) of the clip 10b are attracted to each other, and the sheet member 22 or the like can be held between the clips 10a and 10b. When removing the clamped object, the vicinity of the magnet bodies 14a, 13b on the lower surface side of the clips 10a, 10b may be pressed from both sides. When such two clips 10a and 10b are used, clothes, bath towels, sheets and the like can be held in addition to the sheet member, and the clips 10a and 10b are used as clothespins. be able to. Further, as shown in FIG. 3C, the sheet member 23 can be sandwiched between the clips 10a and 10b, and the sheet member 22 can be further sandwiched from above.

  FIG. 4 is a diagram showing an example when a combination of two clips of FIG. 3 is attracted to the magnetic surface. As shown in FIG. 2, the sheet member can be held by attracting the magnet body to the magnetic surface using one clip 10, but as shown in FIG. 4, the clips 10a and 10b of FIG. When a combination of the clips 10a and 10b is used, the upper surface 1A side of the clicks 10a and 10b is attracted to the magnetic surface 20 by the magnet bodies 11a to 14a, so that the combination of the two clips 10a and 10b is attracted to the magnetic surface 20. Thus, the sheet member or the like can be held.

  At this time, the upper surfaces 1A of the clips 10a and 10b are in direct contact with the magnetic surface 20. However, if the upper surfaces 1A of the clips 10a and 10b are made of a material that is slippery with respect to the magnetic surface 20, the clips 10a and 10b. There is a risk of falling by its own weight. Therefore, a non-slip member (rubber or rubber product) 1B as shown in FIG. 4B is provided on the upper surface 1A of the clips 10a and 10b. As a result, the clips 10a and 10b themselves do not fall due to their own weight due to friction between the magnetic surface 20 and the anti-slip member 1B. Further, when two clips are used in combination as shown in FIG. 3, the magnet body may be provided on the clip surface side and the surface thereof may be attracted to the magnetic material surface. For example, the anti-slip member 1B shown in FIG. 4 may be formed of a magnet body, or a magnet may be embedded in the anti-slip member 1B.

  In the above-described embodiment, the case where the shape of the upper surface 1A of the clips 10a and 10b is formed by a part of a spherical surface has been described. However, the present invention is not limited to this, and any shape may be used. Not too long. In this case, the shape of the anti-slip member may be appropriately changed.

  Further, when the sheet member 22 is held by adhering any one of the magnet bodies 11 to 14 to the magnetic body surface 20 with one clip 10 as shown in FIG. 2, the polarities of the magnet bodies 11 to 14 are , Any way you want. That is, the bottom surface of the magnet bodies 11 to 14 may be either S pole or N pole, but when considering using two clips 10a and 10b in combination as shown in FIGS. It is preferable that the polarities of the bottom surface portions of the magnet bodies 11 to 14 in the point-symmetrical positions are matched.

  Thus, by making the polarities of the bottom surfaces of the magnet bodies 11 to 14 in the point-symmetrical positions coincide with each other, the clip facing the magnet body 12a of the clip 10a in the attracted state as shown in FIGS. The magnet bodies 11b of 10b are attracted to each other because they have different polarities, but the magnet bodies 14b and 12b of the clip 10b located on both sides of the magnet body 12a of the clip 10a have the same polarity and repel each other. . Similarly, since the magnet bodies 11a and 13a of the clip 10a located on both sides of the magnet body 11b of the clip 10b have the same polarity, they repel each other. Therefore, as shown in FIGS. 3 and 4, even if the clips 10a and 10b attracted to each other by the magnet bodies 14a and 13b are subjected to rotational stress around the attracted portion, the aforementioned adjacent magnet bodies repel each other. Thus, there is an effect that the clips 10a and 10b are difficult to rotate.

  In the above-described embodiment, the case where four magnet bodies are provided has been described. However, as shown in FIG. 5A, three magnet bodies may be provided on three tapered bottom surfaces. In the case where three magnet bodies are provided on three tapered bottom surfaces as shown in FIG. 5A, when two clips are used in combination, in addition to FIG. As shown in B), two types of clips having different magnet body polarities must be created. Further, the number of magnet bodies provided on the tapered bottom surface is not limited to one, and a plurality of magnet bodies may be provided as shown in FIG. Further, as shown in FIG. 5D, two magnet bodies may be provided on two tapered bottom surfaces. In addition, in the case where two magnet bodies are provided as shown in FIG. 5 (D), when two clips are used in combination, as described above, when rotational stress is applied around the attracting point, There is a drawback that it rotates easily. Thus, as described above, as shown in FIG. 5 (E), by providing a plurality of magnet bodies on the tapered bottom surface, it is possible to prevent simple rotation due to rotational stress.

  In the embodiment of FIG. 4, the case where the anti-slip member (rubber or rubber product) is provided on the upper surface 1 </ b> A has been described, but such an anti-slip member may be provided on the tapered bottom surface portion. In this case, an anti-slip member may be provided around the magnet body. Further, by processing the outer shape of the circular clip as shown in FIGS. 5 (A) and 5 (B) as shown in FIG. 5 (F) and adding a bear character picture or the like on the upper surface, The clip can be configured. Similarly, various clips may be formed by processing a circular clip into an appropriate shape and adding a pattern or the like. Further, the shape of the clip and the angle of the thickness taper shown in the above-described embodiment are design matters, and are not limited to those shown in the drawings, and can be changed as appropriate.

  FIG. 6 is a diagram illustrating a first modification of the clip. In the above embodiment, the case where the clip surface is circular has been described. However, as shown in FIG. 5, hook portions 61 to 64 may be provided on the surface of the clip 10. In the figure, four hook portions 61 to 64 are provided, but the number of hook portions may be arbitrary. Further, the hook portion can be applied to the various clips shown in this embodiment, and two hook portions with and without the hook portion may be combined.

  FIG. 7 is a diagram illustrating a second modification of the clip. Here, as shown in FIG. 5D, the clips 71 to 74 are provided with concavity and convexity portions for coupling on the side surfaces of the rectangular main body portion having two tapered bottom surfaces, respectively. 74 can be connected to each series. Thus, the clamping force can be adjusted by connecting a plurality of clips 71 to 74. 7A shows a case where the N pole and the S pole are continuously connected in the same direction, and FIG. 7B shows a case where the N pole and the S pole are alternately connected.

  In the above-described embodiment, a printed matter such as novelty may be affixed to each clip surface side (side where no magnet body is provided), or a transparent cover may be provided to protect the printed matter. Moreover, although the case where the magnet body is provided on one side surface has been described, it may be provided on both side surfaces as well.
