[0016] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0017] Fig. 1 is a perspective view showing a part of a magnetic material removal tool 100 according to an embodiment of the present invention. Fig. 2 is a perspective view showing another part of the magnetic material removal tool 100 of Fig. 1. Fig. 3 is a perspective view showing the magnetic material removal tool 100 of Fig. 1 in a state where the handle 40 has been rotated relative to the main body 10. First, an overview of the magnetic material removal tool 100 will be described with reference to Figs. 1 to 3.

[0018] 1 and 2, a magnetic material removal tool 100 according to an embodiment of the present invention is used to remove magnetic material 1 such as iron powder (see FIG. 9, etc.), and includes a main body 10, a handle 40, and a moving mechanism 50. In addition, the magnetic material removal tool 100 includes a magnet 20 and a yoke 30 (see FIG. 5, etc.) housed in the main body 10, as will be described in detail later.

[0019] The main body 10 has a first attachment surface 16 , a second attachment surface 17 , and a first grip portion 12 .

[0020] The first attachment surface 16 and the second attachment surface 17 are surfaces for attaching the magnetic body 1 outside the main body 10. As described above, the main body 10 contains the magnet 20, and the magnetic force of the magnet 20 can attract the magnetic body 1 outside the main body 10 and attach it to the first attachment surface 16 and the second attachment surface 17.

[0021] The first grip portion 12 is a portion that is gripped by a user of the magnetic material removal tool 100. When the handle 40 is detached from the main body 10, the user can use the magnetic material removal tool 100 by gripping the first grip portion 12.

[0022] The handle 40 is detachably attached to the main body 10. The handle 40 has an attachment portion 41 and a second grip portion .

[0023] Mounting portion 41 is a mounting tool for detachably mounting handle 40 to main body 10, and is arranged at one end of handle 40. Mounting portion 41 is detachably mounted to mounting portion 15 of main body 10. The method for mounting handle 40 to main body 10 is not particularly limited, and any method may be used as long as it allows handle 40 to be detachably mounted to main body 10.

[0024] The second grip part 42 is a part that is gripped by a user of the magnetic material removal tool 100. With the handle 40 attached to the main body 10, the user can use the magnetic material removal tool 100 by gripping the second grip part 42. The second grip part 42 is disposed at the other end of the handle 40.

[0025] The moving mechanism 50 is a mechanism for moving the magnet 20 between a first position (see FIG. 5, etc.) where the magnetic body 1 can be attracted by magnetic force and attached to the first attachment surface 16 and the second attachment surface 17, and a second position (see FIG. 7, etc.) located on the other side of the first position in a first direction (the X-axis direction in FIG. 1, etc.) (the negative side of the X-axis direction in FIG. 1, etc.) where the magnetic body 1 cannot be attached to the first attachment surface 16 or the second attachment surface 17. The first direction is an example of a predetermined direction. The moving mechanism 50 has a first movable part 51, a first connecting part 52, a second movable part 54, and a second connecting part 55.

[0026] The first movable part 51 is movable relative to the first gripping part 12. The first connecting part 52 connects the magnet 20 to the first movable part 51 so that the magnet 20 moves between a first position and a second position as the first movable part 51 moves relative to the first gripping part 12.

[0027] The second movable part 54 is movable relative to the second gripping part 42. The second connecting part 55 connects the first movable part 51 and the second movable part 54 so that the first movable part 51 moves relative to the first gripping part 12 as the second movable part 54 moves relative to the second gripping part 42. The second connecting part 55 includes a rod body 55a and a wire 55b.

[0028] Rod 55a is connected to second movable part 54 and is slidably supported on handle 40 inside handle 40. Wire 55b is connected to rod 55a and first movable part 51. By moving second movable part 54 relative to second gripping part 42, first movable part 51 moves relative to first gripping part 12 via rod 55a and wire 55b. This allows magnet 20 to move and position magnet 20 between a first position and a second position.

[0029] For example, when using the magnetic body remover 100 to remove a magnetic body 1 that has fallen on the floor or the like, a user holds the second gripping portion 42 with the handle 40 attached to the main body 10 and brings the first attachment surface 16 close to the magnetic body 1. When the first attachment surface 16 is brought close to the magnetic body 1, the magnetic body 1 is attracted by the magnetic force of the magnet 20 and adheres to the first attachment surface 16. With the magnetic body 1 adhered to the first attachment surface 16, the user moves the first attachment surface 16 above a collection container or the like (not shown) and pulls the second movable portion 54 away from the main body 10. With the second movable portion 54 pulled away from the main body 10, the magnet 20 is in the second position, and the magnetic body 1 adhered to the first attachment surface 16 falls and is collected in a collection container or the like.

[0030] Furthermore, for example, if the handle 40 gets in the way and the user is unable to bring the first attachment surface 16 close to the magnetic body 1, the user can remove the handle 40 from the main body 10, grasp the first gripping part 12, and bring the first attachment surface 16 close to the magnetic body 1. In this case, the user moves the first attachment surface 16, to which the magnetic body 1 is attached, above a collection container or the like and pulls the first movable part 51 toward the first gripping part 12. With the first movable part 51 pulled toward the first gripping part 12, the magnet 20 is in the second position, just as in the case where the second movable part 54 is pulled away from the main body 10, and the magnetic body 1 attached to the first attachment surface 16 falls and is collected in a collection container or the like.

[0031] 3, the handle 40 is rotatable relative to the main body 10. Therefore, for example, the user can use the magnetic material remover 100 by adjusting the angle of the handle 40 relative to the main body 10 to an angle that makes it easy to bring the first attachment surface 16 close to the magnetic material 1.

[0032] The outline of the magnetic material removal tool 100 has been explained above.

[0033] Fig. 4 is a bottom view showing the magnetic material removal tool 100 of Fig. 1 with the handle 40 detached from the main body 10. Fig. 5 is a cross-sectional view taken along line AA in Fig. 4, showing the magnet 20 in a state where it is located at the first position. Fig. 6 is a cross-sectional view taken along line BB in Fig. 4, showing the magnet 20 in a state where it is located at the first position. Fig. 7 is a cross-sectional view taken along line AA in Fig. 4, showing the magnet 20 in a state where it is located at the second position. Fig. 8 is a cross-sectional view taken along line BB in Fig. 4, showing the magnet 20 in a state where it is located at the second position. Next, the magnetic material removal tool 100 will be described in detail with reference to Figs. 4 to 8.

[0034] As shown in FIGS. 4 to 8, the magnetic body remover 100 includes a main body 10, a magnet 20, a yoke 30, a handle 40, and a movement mechanism 50.

[0035] The main body 10 has an attachment surface forming portion 11, a first gripping portion 12, a connecting portion 13, a support portion 14, and an attachment portion 15. For example, the attachment surface forming portion 11, the first gripping portion 12, the connecting portion 13, and the support portion 14 are formed of a non-magnetic material.

[0036] The attachment surface forming portion 11 forms an attachment surface for attaching the magnetic body 1. The attachment surface forming portion 11 has a first attachment surface 16 and a second attachment surface 17.

[0037] The first attachment surface 16 is a surface for attaching a magnetic material. The first attachment surface 16 is located on one side of the magnet 20 in the first direction (the positive side in the X-axis direction in FIG. 1, etc.). The first attachment surface 16 has a flat portion 16a and a protruding portion 16b.

[0038] The planar portion 16a is located on one side of the magnet 20 in the first direction. In other words, the planar portion 16a overlaps with the magnet 20 in the first direction. The planar portion 16a extends in a second direction (the Y-axis direction in FIG. 5, etc.) that is perpendicular to the first direction, and also extends in a third direction (the Z-axis direction in FIG. 5, etc.) that is perpendicular to the first direction and perpendicular to the second direction. The planar portion 16a is elongated in the second direction. The second direction is an example of an intersecting direction that intersects with a predetermined direction. The second direction and the third direction are also examples of orthogonal directions that are perpendicular to the predetermined direction.

[0039] The protrusion 16b protrudes to one side in the first direction. Specifically, the protrusion 16b protrudes from the flat surface 16a to one side in the first direction. A plurality of the protrusions 16b are arranged in the second direction. The protrusions 16b are arranged in the center of the flat surface 16a in the third direction. The protrusions 16b are located on one side of the magnet 20 in the first direction. In other words, the protrusions 16b overlap with the magnet 20 in the first direction. The protrusions 16b have an inclined portion 16c (see FIG. 4).

[0040] Protrusion 16b is inclined so that its width gradually narrows toward one side in the first direction, and inclined portion 16c is an inclined surface of protrusion 16b. Protrusion 16b is inclined so that its width gradually narrows toward one side in the first direction when viewed from the second direction, and the inclined surface is inclined with respect to the first direction.

[0041] When the magnet 20 is located at the first position, the second attachment surface 17 is located in the second direction and also in the third direction relative to the magnet 20. In this embodiment, when the magnet 20 is located at the first position, the second attachment surface 17 is arranged in a substantially rectangular shape so as to surround the magnet 20 in the first direction. The second attachment surface 17 has a first surface portion 17a and a second surface portion 17b.

[0042] First surface portion 17a extends in the first direction. In the present embodiment, first surface portion 17a extends from the peripheral edge of flat surface portion 16a to the other side in the first direction, is arranged along the peripheral edge of flat surface portion 16a, and is arranged in a substantially rectangular shape so as to surround magnet 20 in the first direction when magnet 20 is located at the first position.

[0043] Second surface portion 17b extends from the other end of first surface portion 17a in the first direction to the side opposite magnet 20 in the orthogonal direction perpendicular to the first direction. Second surface portion 17b is arranged in a substantially rectangular shape around the first direction along the other end of first surface portion 17a in the first direction. When magnet 20 is located at the second position, second surface portion 17b is located on one side of magnet 20 in the first fixed direction.

[0044] The first gripping portion 12 is located on the other side of the first attachment surface 16 and the magnet 20 in the first direction, and extends in the second direction. The first gripping portion 12 is cylindrical.

[0045] The connecting portion 13 connects the attachment surface forming portion 11 and the first grip portion 12. The connecting portion 13 has a peripheral wall portion 13a and pillar portions 13b and 13c.

[0046] The peripheral wall 13a is connected to the attachment surface forming portion 11. The peripheral wall 13a is annular in the first direction, and the magnet 20 and the yoke 30 are housed inside the attachment surface forming portion 11 and the peripheral wall 13a so as to be movable in the first direction. The peripheral wall 13a has a groove 13d at the end on the other side in the first direction that opens in the first direction and extends in the second direction. The first connecting portion 52 is inserted into the groove 13d so as to be slidable in the first direction.

[0047] The pillar portion 13b extends in the first direction and is connected to the peripheral wall portion 13a and an end portion on one side of the first grip portion 12 in the second direction (the positive side in the Y-axis direction in FIG. 4, etc.). The pillar portion 13b is cylindrical. At the end portion on the other side in the second direction (the negative side in the Y-axis direction in FIG. 4, etc.), the pillar portion 13b has a groove portion 13e that opens in the second direction, extends in the first direction, and communicates with the groove portion 13d. The first connecting portion 52 is inserted into the groove portion 13e so as to be slidable in the first direction.

[0048] The pillar portion 13c extends in the first direction and is connected to the other end of the first grip portion 12 in the second direction and to the peripheral wall portion 13a. The pillar portion 13c is cylindrical. At one end of the pillar portion 13c in the second direction, the pillar portion 13c has a groove portion 13f that opens in the second direction, extends in the first direction, and communicates with the groove portion 13d. The first connecting portion 52 is inserted into the groove portion 13f so as to be slidable in the first direction.

[0049] The support portion 14 extends in a first direction. The support portion 14 is disposed inside the pillar portion 13b and supports the sliding portion 53 of the movement mechanism 50 so that the sliding portion 53 can slide in the first direction. The support portion 14 is also disposed inside the pillar portion 13c and supports the sliding portion 53 of the movement mechanism 50 so that the sliding portion 53 can slide in the first direction.

[0050] The attachment part 15 is housed in the first grip part 12. The attachment part 15 is a mounting fixture for detachably mounting the handle 40. The attachment part 15 has a structure to which the attachment part 41 of the handle 40 can be detachably mounted. The attachment part 15 also has a rotation mechanism, which allows the handle 40 to rotate relative to the main body 10.

[0051] The magnet 20 is housed in the main body 10. The magnet 20 can use its magnetic force to attract the magnetic body 1 outside the main body 10 and attach it to the first attachment surface 16. The magnet 20 can also use its magnetic force to attract the magnetic body 1 outside the main body 10 and attach it to the second attachment surface 17. In this embodiment, when the magnet 20 is located at the first position, it can use its magnetic force to attract the magnetic body 1 outside the main body 10 and attach it to the first attachment surface 16 and the second attachment surface 17. When the magnet 20 is located at the second position, it cannot use its magnetic force to attract the magnetic body 1 outside the main body 10 and attach it to the first attachment surface 16 and the second attachment surface 17.

[0052] The magnet 20 is magnetized in a first direction, for example, so that one side in the first direction is a south pole and the other side in the first direction is a north pole. The magnet 20 is elongated in a second direction and has a substantially rectangular parallelepiped shape.

[0053] The yoke 30 is open on one side in the first direction, and the magnet 20 is disposed inside the yoke 30. The yoke 30 extends in the second and third directions on the other side of the magnet 20 in the first direction and is connected to the magnet 20. The yoke 30 extends in the first and second directions on one side of the magnet 20 in the third direction (the positive side in the Z-axis direction in FIG. 4, etc.) and faces the magnet 20 with a gap. The yoke 30 extends in the first and second directions on the other side of the magnet 20 in the third direction (the negative side in the Z-axis direction in FIG. 4, etc.) and faces the magnet 20 with a gap. The yoke 30 is elongated in the second direction. For example, the yoke 30 is magnetized by the magnet 20 so that one end of the yoke 30 in the first direction becomes the north pole.

[0054] As described above, the movement mechanism 50 has the first movable part 51, the first connecting part 52, the second movable part 54, and the second connecting part 55. The movement mechanism 50 also has the sliding part 53.

[0055] The first movable part 51 is movable relative to the first grip part 12. In this embodiment, the first movable part 51 extends in the second direction, is located on one side of the first grip part 12 in the first direction, and is movable in the first direction. The first movable part 51 is arranged such that the magnet 20 is located in the first position when not operated by the user.

[0056] The first connecting portion 52 connects the magnet 20 and the first movable portion 51 such that the magnet 20 moves between a first position and a second position as the first movable portion 51 moves relative to the first gripping portion 12. For example, the magnet 20 is positioned at the second position by moving the first movable portion 51 to a position where the first movable portion 51 contacts the first gripping portion 12. The first connecting portion 52 is formed so as to branch into two on the first movable portion 51 side, and is connected to both ends of the first movable portion 51 in the second direction. The first connecting portion 52 is formed integrally with the first movable portion 51. The first connecting portion 52 is fixed to the yoke 30 by a bolt or the like, and is fixed to the magnet 20 via the yoke 30.

[0057] The sliding portion 53 extends in the first direction. The sliding portion 53 is disposed on one side of the first connecting portion 52 in the second direction, and is supported by the support portion 14 so as to be slidable in the first direction. The sliding portion 53 is also disposed on the other side of the first connecting portion 52 in the second direction, and is supported by the support portion 14 so as to be slidable in the first direction.

[0058] The magnetic material removal tool 100 has been described in detail above.

[0059] Fig. 9 is a schematic diagram showing a first use example of the magnetic material removal tool 100 of Fig. 1. Fig. 10 is a schematic diagram showing a second use example of the magnetic material removal tool 100 of Fig. 1. Fig. 11 is a schematic diagram showing a third use example of the magnetic material removal tool 100 of Fig. 1. Fig. 12 is a schematic diagram showing a fourth use example of the magnetic material removal tool 100 of Fig. 1. Next, first to fourth use examples of the magnetic material removal tool 100 will be described with reference to Figs. 9 to 12.

[0060] First, a first use example will be described with reference to FIG. 9. As shown in FIG. 9(a), when removing a magnetic object 1 that has fallen on the floor, the first attachment surface 16 is brought close to the magnetic object 1. As shown in FIG. 9(b), when the first attachment surface 16 is brought close to the magnetic object 1 to a certain extent, the magnetic object 1 adheres to the first attachment surface 16. As shown in FIG. 9(c), the first attachment surface 16 to which the magnetic object 1 has adhered is moved above a collection container or the like, and the magnet 20 is moved to a second position, whereby the magnetic object 1 can be dropped and placed in the collection container or the like. In this way, the magnetic object 1 that has fallen on the floor can be removed.

[0061] Next, a second use example will be described with reference to Fig. 10. As shown in Fig. 10(a), when the magnet 20 is moved to the second position from a state in which the magnetic body 1 is attached to the first attachment surface 16, as shown in Fig. 10(b), as the magnet 20 moves to the other side in the first direction, the magnetic body 1 may also move to the other side in the first direction. As shown in Fig. 10(c), even if the magnetic body 1 also moves to the other side in the first direction as the magnet 20 moves to the other side in the first direction, the second attachment surface 17 prevents the magnetic body 1 from moving to the other side in the first direction, and the magnet 20 can be moved to the other side in the first direction to be positioned at the second position. Therefore, the magnetic body 1 can be dropped from the second attachment surface 17 and placed in a collection container or the like.

[0062] Next, a third use example will be described with reference to FIG. 11 . As shown in FIG. 11 (a), when a magnetic body 1 is lodged in a groove in a deck plate or the like, the protrusion 16b is positioned to locate in the groove. In the magnetic body remover 100, the magnet 20 and the yoke 30 can generate a magnetic force that makes it difficult for the deck plate to be magnetized (see the thick arrow in FIG. 11 (a)), thereby preventing the deck plate from being magnetized. This allows the magnetic body 1 to be attracted more reliably, and the magnetic body 1 can be attached to the first attachment surface 16, as shown in FIG. 11 (b). As shown in FIG. 11 (c), when the magnetic body 1 is attached to the first attachment surface 16, the first attachment surface 16 is moved away from the groove, thereby removing the magnetic body 1 that has lodged in the groove.

[0063] Next, a fourth usage example will be described with reference to FIG. 12. As shown in FIG. 12(a), when the magnetic body 1 has fallen into a corner between a wall and a floor, the protrusion 16b is brought close to the corner. In this way, the magnetic body 1 can be attracted. As shown in FIG. 12(b), when the magnetic body 1 is attached to the first attachment surface 16, the first attachment surface 16 is moved away from the corner, whereby the magnetic body 1 that has fallen into the corner can be removed.

[0064] The first to fourth examples of use of the magnetic material remover 100 have been described above.

[0065] As described above, the magnetic body removal tool 100 in the above-mentioned embodiment of the present invention comprises a main body 10 and a magnet 20 housed in the main body 10, the main body 10 is located on one side of the magnet 20 in a predetermined direction (first direction) and has a first attachment surface 16 for attaching a magnetic body 1 outside the main body 10, the magnet 20 can attract the magnetic body 1 by magnetic force and attach it to the first attachment surface 16, and the first attachment surface 16 has a protrusion 16b protruding on one side in the predetermined direction (first direction).

[0066] As a result, since the first attachment surface 16 has a protrusion 16b, a gap can be formed between the magnetic body 1 and the first attachment surface 16 while preventing the magnet 20 from getting too close to the magnetic body 1, making it easier to attach the magnetic body 1 to the first attachment surface 16 and allowing the magnetic body 1 to be removed more efficiently than before.

[0067] Furthermore, in the magnetic material removal tool 100 according to the embodiment of the present invention described above, the width of the protrusion 16b gradually narrows toward one side in the predetermined direction (first direction).

[0068] According to this, when the magnetic body 1 has entered a narrow gap or fallen into a corner, the protrusion 16b can be prevented from interfering with the first attachment surface 16 when it is brought close to the gap or corner, and therefore the magnetic body 1 can be removed more efficiently.

[0069] Furthermore, in the magnetic body removal tool 100 according to the embodiment of the present invention described above, the first attachment surface 16 is elongated in a cross direction (second direction) that crosses a predetermined direction (first direction), and multiple protrusions 16b are arranged in the cross direction (second direction).

[0070] This makes it easier to form a gap between the magnetic body 1 and the first attachment surface 16, making it easier to attach the magnetic body 1 to the first attachment surface 16 and allowing the magnetic body 1 to be removed more efficiently.

[0071] In the magnetic body remover 100 according to the embodiment of the present invention described above, the protrusion 16b is located on one side of the magnet 20 in the predetermined direction (first direction).

[0072] This makes it easier for the magnetic body 1 to adhere to the protrusion 16b, so that the magnetic body 1 can be removed more efficiently.

[0073] Furthermore, the magnetic body removal tool 100 in the above-described embodiment of the present invention is provided with a moving mechanism 50 for moving the magnet 20 to a first position where the magnetic body 1 can be attracted by magnetic force and attached to the first attachment surface 16, and a second position located on the other side of the first position in a predetermined direction (first direction) and where the magnetic body 1 cannot be attached to the first attachment surface 16.

[0074] According to this, the magnetic material 1 adhered to the first attachment surface 16 can be more easily removed from the first attachment surface 16, and therefore the magnetic material 1 can be removed more efficiently.

[0075] Furthermore, in the magnetic body removal tool 100 in the embodiment of the present invention described above, the main body 10 is positioned in an orthogonal direction (second direction, third direction) perpendicular to the predetermined direction (first direction) relative to the magnet 20 when the magnet 20 is positioned at the first position, and has a second attachment surface 17 for attaching the magnetic body 1, and when the magnet 20 is positioned at the first position, the magnetic body 1 can be attracted by magnetic force to attach to the second attachment surface 17, and the second attachment surface 17 has a first surface portion 17a extending in the predetermined direction (first direction) and a second surface portion 17b extending from the other end of the first surface portion 17a in the predetermined direction (first direction) to the opposite side to the magnet 20 in the orthogonal direction (second direction, third direction), and when the magnet 20 is positioned at the second position, the second surface portion 17b is positioned on one side of the magnet 20 in the predetermined direction (first direction).

[0076] According to this, even if the magnetic body 1 attached to the first attachment surface 16 or the second attachment surface 17 moves to the other side in the specified direction as the magnet 20 moves to the other side in the specified direction, the second surface portion 17b can prevent the magnetic body 1 from moving, and the magnetic body 1 can be more easily removed from the second attachment surface 17, thereby making it possible to remove the magnetic body 1 more efficiently.

[0077] Furthermore, the magnetic body removal tool 100 in the embodiment of the present invention described above includes a handle 40 that is detachably attached to the main body 10, the main body 10 having a first gripping portion 12, the handle 40 having a second gripping portion 42, and the moving mechanism 50 having a first movable portion 51 that can move relative to the first gripping portion 12, a first connecting portion 52 that connects the magnet 20 and the first movable portion 51 so that the magnet 20 moves between a first position and a second position as the first movable portion 51 moves relative to the first gripping portion 12, a second movable portion 54 that can move relative to the second gripping portion 42, and a second connecting portion 55 that connects the first movable portion 51 and the second movable portion 54 so that the first movable portion 51 moves relative to the first gripping portion 12 as the second movable portion 54 moves relative to the second gripping portion 42.

[0078] This allows the magnet 20 to be moved to the second position with the handle 40 attached to the main body 10, and also allows the magnet 20 to be moved to the second position with the handle 40 detached from the main body 10, so that the magnetic body 1 can be removed even more efficiently.

[0079] Moreover, the magnetic body remover 100 in the above-described embodiment of the present invention includes a yoke 30 that opens on one side in a predetermined direction (first direction) and has the magnet 20 disposed inside.

[0080] According to this, the magnetic force of the magnet 20 can be directed toward the magnetic body 1, making it easier to attract the magnetic body 1, and the magnetic body 1 can be removed more efficiently.

[0081] Although the embodiments of the present invention have been described above, they are merely illustrative examples and do not limit the present invention, and the specific configurations and the like can be appropriately modified in design. Furthermore, the actions and effects described in the embodiments of the invention are merely a list of the most preferable actions and effects resulting from the present invention, and the actions and effects of the present invention are not limited to those described in the embodiments of the present invention.

[0082] In the above-described embodiment, the protrusion 16b is inclined so that its width gradually narrows toward one side in the first direction, but this is not limiting. For example, the protrusion may be curved convexly toward one side in the first direction so that its width gradually narrows toward one side in the first direction. Furthermore, the protrusion may not be gradually narrowed toward one side in the first direction. [Explanation of symbols]
