Description

[Technical field]

[0001] The present invention relates to a fitting. [Background technology]

[0002] Conventionally, methods using adhesives and methods using rivets have been known as methods for attaching objects such as photovoltaic panels to a mounting surface such as a wall surface. However, these methods require a lot of work for the mounting work, and when the object is removed from the mounting surface, dirt, holes, etc. may remain on the mounting surface.

[0003] As a method for attaching and detaching an object without soiling the attachment surface, for example, a method using a magnet is known. For example, Patent Document 1 discloses an object having a metal attached to its back surface and an attachment unit having a magnet attached to its front surface. The object and attachment unit disclosed in Patent Document 1 are configured so that, with the attachment unit attached to the wall surface, the magnet of the attachment unit is attracted to the metal of the object by magnetic force, thereby allowing the object to be attached to the wall surface.

[0004] [Patent Document 1] JP 20121-94052 A Summary of the Invention

[0005] (Problem to be solved by the invention) Incidentally, when attaching a solar panel to a wall surface as described above, it is required to attach the solar panel with a strong magnetic force so that the solar panel will not be detached from the wall surface due to wind or the like. On the other hand, if the magnetic force is made too strong, it will be difficult to remove the object from the object during maintenance or the like. Also, the configuration described in Patent Document 1 requires a metal to be attached to the object and an attachment unit that is separate from the object. This results in a large number of components.

[0006] In view of the above situation, the problem that the present invention aims to solve is to provide a mounting fixture that can increase the mounting force of an object to an object being attached to, while allowing the object to be easily detached from the object being attached to, and that can prevent or suppress an increase in the number of parts (or types of parts).

[0007] (Means for solving the problem) In order to solve the above problems, the mounting tool according to the present invention comprises: A mounting tool for removably mounting an object to a mounting surface of an object by magnetic force, A magnet, a contact magnetic member formed of a ferromagnetic material, the contact magnetic member having an attachment surface configured to be capable of surface-to-surface contact with the attachment surface and a tool contact surface configured to be capable of surface-to-surface contact with a part of a removal tool, the contact magnetic member being in contact with a surface on which one pole of the magnet appears; a non-contact magnetic member formed of a ferromagnetic material, the non-contact magnetic member having an opposing surface configured to be spaced apart from the attached surface with a predetermined gap when the attachment surface of the contact magnetic member is in surface contact with the attached surface, and a tool contact surface configured to be capable of surface contacting another part of the removal tool, the non-contact magnetic member being in contact with a surface on which the other pole of the magnet appears; Equipped with When the mounting surface comes into surface contact with the mounting surface, a magnetic path is formed from the magnet through the contact magnetic member, the mounting object, and the non-contact magnetic member to the magnet, When the removal tool is attached so as to contact the tool contact surface of the contact magnetic member and the tool contact surface of the non-contact magnetic member, another magnetic path is formed from the magnet through the contact magnetic member, the removal tool, and the non-contact magnetic member to the magnet.

[0008] When the mounting tool is attached to the mounting surface of the object, a magnetic path is formed from the magnet through the contact magnetic member, the object, and the non-contact magnetic member to the magnet. Therefore, the mounting tool is firmly attached to the object by the magnetic force. On the other hand, when the removal tool is attached so as to contact both the tool contact surface of the contact magnetic member and the tool contact surface of the non-contact magnetic member, another magnetic path is formed from the magnet through the contact magnetic member, the removal tool, the non-contact magnetic member, and the magnet. By forming such another magnetic path, the magnetic flux passing through the magnetic path is reduced (magnetic flux density is reduced). Therefore, the magnetic force (mounting force) between the mounting tool and the object is reduced, and the mounting tool can be easily removed from the object. In addition, since the mounting unit described in Patent Document 1 is not required, an increase in the number of parts can be prevented or suppressed. [Brief description of the drawings]

[0010] The mounting tool according to each embodiment of the present invention is configured to detachably mount an object (an object to be mounted by the mounting tool) on the surface of a ferromagnetic object (an object to which the object is to be mounted). Hereinafter, this surface may be referred to as the "mounted surface". The mounted surface is flat. For ease of explanation, the direction perpendicular to the mounted surface when the mounting tool is mounted on the mounted surface may be referred to as the "mounting direction", one side of the mounting direction that is closer to the mounted surface may be referred to as the "near side", and the other side of the mounting direction that is farther from the mounted surface may be referred to as the "remote side". In each drawing, the near side of the mounting direction is indicated by an arrow N, and the remote side of the mounting direction is indicated by an arrow F.

[0011] In each embodiment of the present invention, a photovoltaic panel 80 is shown as an example of an object of the mounting fixture 10, 30, and a metal insulation sandwich panel 90 is shown as an example of an object to be mounted. The photovoltaic panel 80 includes, for example, a sheet-shaped power generating element 801, a sealing sheet 802 (for example, an EVA sheet) provided to seal the sheet-shaped power generating element 801, a back sheet 803 (for example, glass or an ETFE sheet) provided to be laminated on one side (the side opposite to the side irradiated with sunlight) of the sealing sheet 802, and a protective sheet 804 (for example, glass or an ETFE sheet) provided to be laminated on the other side (the side irradiated with sunlight) of the sealing sheet 802 (see Figs. 3 and 4). The metal insulation sandwich panel 90 is a building material that is applied to, for example, the wall surface of a building, and includes a laminated structure of two steel plates 901 and a heat insulating material 902 sandwiched between them (see Figs. 3 and 4). The metal insulation sandwich panel 90 having this configuration contains steel plates, which are ferromagnetic, and therefore attracts magnets.

[0012] First Embodiment 1A and 1B are perspective views showing the configuration of a mounting tool 10 and a removal tool 20 according to the first embodiment. FIGS. 2A and 2B are exploded perspective views showing the configuration of a mounting tool 10 according to the first embodiment. As shown in these figures, the mounting tool 10 includes a first magnet 11, a first yoke 12, a second yoke 13, and a coating filler 14. The first magnet 11 is an example of the magnet of the present invention, the first yoke 12 is an example of the contact magnetic member of the present invention, and the second yoke 13 is an example of the non-contact magnetic member of the present invention.

[0013] Various known magnets can be used for the first magnet 11. In the first embodiment, an example is shown in which the first magnet 11 has a rectangular prism shape. In this case, the direction of polarization of the first magnet 11 is perpendicular to the longitudinal direction of the first magnet 11. The first magnet 11 is arranged with the direction of polarization substantially parallel to the mounting direction (in other words, one of the S pole and the N pole is located on the proximal side and the other is located on the distal side).

[0014] Both the first yoke 12 and the second yoke 13 are members formed from a soft magnetic material (a magnetic material that has the property of being strongly magnetized in the direction of a magnetic field when the magnetic field is applied, and hardly retaining any magnetization when the magnetic field is removed).

[0015] The first yoke 12 is a member provided with an attachment surface 121, a magnet contact surface 122, and a tool contact surface 123. The attachment surface 121 is a surface configured to be able to come into surface contact directly with the attached surface 903 (see Figs. 3 and 4). The attachment surface 121 is an end surface on the near side of the first yoke 12, and is a plane perpendicular to the attachment direction. The magnet contact surface 122 is a surface configured to be able to come into surface contact with the surface on which one of the S pole and the N pole of the first magnet 11 appears. In this embodiment, the magnet contact surface 122 is an end surface on the far side of the first yoke 12, and is a plane substantially perpendicular to the attachment direction. The tool contact surface 123 is a surface configured to be able to come into surface contact with a first yoke contact surface 201 of a removal tool 20 described later. In this embodiment, the tool contact surface 123 is a plane substantially parallel to the attachment direction.

[0016] In this embodiment, an example is shown in which the first yoke 12 has a rectangular prism shape. In this case, one of the four side faces of the rectangular prism located on the near side is the attachment surface 121, one of the face located on the opposite side (remote side) of the attachment surface 121 is the magnet contact surface 122, and one of the remaining two faces is the tool contact surface 123.

[0017] The second yoke 13 is a member on which the facing surface 131, the magnet contact surface 132, the tool contact surface 133, and the object mounting portion 134 are provided. The facing surface 131 is a surface configured to be able to face the attached surface 903 in approximately parallel. In this embodiment, the facing surface 131 is an end surface on the proximal side of the second yoke 13, and is a flat surface approximately perpendicular to the attachment direction. The magnet contact surface 132 is a surface configured to be able to contact a surface on which the other of the S pole and the N pole of the first magnet 11 (the pole opposite to the pole that contacts the magnet contact surface 122) appears. The tool contact surface 133 is a surface configured to be able to come into surface contact with the removal tool 20 described later. The magnet contact surface 132 and the tool contact surface 133 are flat surfaces provided at a position spaced away from the facing surface 131 on the remote side.

[0018] In this embodiment, an example is shown in which the second yoke 13 includes a vertical plate portion 135 and a horizontal plate portion 136. The vertical plate portion 135 is a portion having a strip-like shape that stands in a direction substantially parallel to the mounting direction and is long in a direction substantially perpendicular to the mounting direction. The horizontal plate portion 136 is a portion having a strip-like shape that extends from the end portion of the remote side of the vertical plate portion 135 to one side in a direction perpendicular to the mounting direction and is long in a direction substantially perpendicular to the mounting direction. Therefore, the second yoke 13 includes a rod-like portion having a substantially "L"-shaped cross section formed by the vertical plate portion 135 and the horizontal plate portion 136. In this case, the end surface on the near side of the vertical plate portion 135 is the facing surface 131, the surface on the near side of the horizontal plate portion 136 is the magnet contact surface 132, and the surface on the remote side of the horizontal plate portion 136 (the surface opposite to the magnet contact surface 132) is the tool contact surface 133.

[0019] The object mounting section 134 is a portion configured so that the photovoltaic power generation panel 80, which is the object, can be mounted thereon (or can be attached to the object). For example, the object mounting section 134 has a strip-like (flat) configuration extending from the vertical plate section 135 on the opposite side to the extending direction of the horizontal plate section 136 and in a direction parallel to the opposing surface 131. The object mounting section 134 is provided in the vicinity of the end of the near side of the vertical plate section 135 and at a position slightly shifted to the remote side from the opposing surface 131 (described later).

[0020] Here, the assembly structure of the fixture 10 will be described. The first yoke 12 is disposed adjacent to the near side of the first magnet 11. The near side surface of the first magnet 11 (the surface on which one pole appears) and the magnet contact surface 122 of the first yoke 12 are in surface contact. The tool contact surface 123 of the first yoke 12 is not flush with one side surface of the first magnet 11, but protrudes from the one side surface of the first magnet 11. The second yoke 13 is disposed so that the facing surface 131 is approximately parallel to the mounting surface 121 of the first yoke 12 and is positioned at a position shifted from the mounting surface 121 to the remote side. The second yoke 13 is disposed so that the magnet contact surface 132 contacts the surface of the first magnet 11 on which the other pole appears. Specifically, the second yoke 13 is disposed so that the vertical plate portion 135 is positioned on the side opposite to the tool contact surface 123 of the first yoke 12, and the horizontal plate portion 136 is positioned on the remote side of the first magnet 11.

[0021] The coating filler 14 is made of a paramagnetic material (a magnetic material that is not magnetized or is hardly magnetized even when a magnetic field is applied). For example, the coating filler 14 is made of a paramagnetic resin material. The coating filler 14 includes an opposing surface coating portion 141 and a magnet coating portion 142. The opposing surface coating portion 141 of the coating filler 14 is a portion that covers the opposing surface 131 of the second yoke 13. The adjacent side surface of the opposing surface coating portion 141 of the coating filler 14 is a plane that is approximately flush with the mounting surface 121 of the first yoke 12 (in other words, the mounting surface 121 of the first yoke 12 and the adjacent side surface of the opposing surface coating portion 141 of the coating material are planes included in the same plane). The magnet coating portion 142 of the coating filler 14 is a portion that covers a surface of the side of the first magnet 11 that is located on the same side as the tool contact surface 123 of the first yoke 12 (a surface facing the same side). The surface of the magnet covering portion 142 of the covering filler 14 is a plane that is substantially flush with the tool contact surface 123 of the first yoke 12. In addition to these portions, the covering filler 14 may have a portion that fills the gap between the first yoke 12 and the first magnet 11 and the vertical plate portion 135 of the second yoke 13. However, the mounting surface 121 and the tool contact surface 123 of the first yoke 12 and the tool contact surface 133 of the second yoke 13 are not covered by the covering filler 14 and are exposed.

[0022] An object is attached to the object attachment portion 134. As described above, if the photovoltaic panel 80, which is the object, is configured to include the sealing sheet 802, the object attachment portion 134 may be configured to be attached to the sealing sheet 802 of the photovoltaic panel 80. For example, the manufacturing process of the photovoltaic panel 80 may include a process of sandwiching the power generating element 801 between two sealing sheets 802 and laminating the two sealing sheets 802 to seal the power generating element 801 with the sealing sheet 802 (a process of embedding the power generating element 801 inside the sealing sheet 802 by joining the two sealing sheets 802 to each other). In this case, a configuration in which the sealing sheet 802 is attached to the object attachment portion 134 by laminating the two sealing sheets 802 in a state where the object attachment portion 134 is sandwiched between them can be applied. In this case, the object attachment portion 134 is embedded inside the sealing sheets 802 that are joined together.

[0023] As described above, the object mounting portion 134 is provided at a position slightly shifted toward the remote side from the mounting surface 121 of the first yoke 12. Therefore, the mounting surface 121 of the first yoke 12 and the surface of the back sheet 803 of the solar power generation panel 80 are substantially flush with each other. In other words, the object mounting portion 134 is provided so that, in a state in which the object is mounted, the back surface of the object (the surface facing the mounted surface 903) is substantially flush with the mounting surface 121 of the first yoke 12, or the back surface of the object is located at a position shifted toward the remote side from the mounting surface 121 of the first yoke 12, so that the mounting surface 121 of the first yoke 12 can be in surface contact with the mounted surface 903.

[0024] The removal tool 20 is a tool used when removing the mounting fixture 10 from the mounting surface 903. The removal tool 20 is formed of a ferromagnetic material. The removal tool 20 is provided with a first yoke contact surface 201 and a second yoke contact surface 202. The first yoke contact surface 201 is a surface configured to be able to come into direct surface contact with the tool contact surface 123 of the first yoke 12, and the second yoke contact surface 202 is a surface configured to be able to come into direct surface contact with the tool contact surface 133 of the second yoke 13. In this embodiment, the removal tool 20 includes a vertical plate portion 203 (extending in a direction substantially parallel to the mounting direction) that is provided to stand upright relative to the mounting surface 903, and a horizontal plate portion 204 that extends from the end of the remote side of the vertical plate portion 203 to one side in the thickness direction of the vertical plate portion 203 (one side in the direction perpendicular to the mounting direction). Therefore, the removal tool 20 has a rod-like shape with a cross section that is substantially "L" shaped. In this case, at least a portion (more specifically, the portion closer to the proximal side) of one side surface of the vertical plate portion 203 (the surface from which the horizontal plate portion 204 protrudes) is the first yoke contact surface 201, and the surface on the proximal side of the horizontal plate portion 204 is the second yoke contact surface 202.

[0025] However, the specific shape of the removal tool 20 is not particularly limited. The specific shape of the removal tool 20 is appropriately set according to the shape, dimensions, and relative positional relationship of the tool contact surface 123 and the tool contact surface 133 of the fixture 10. Furthermore, the removal tool 20 may include a portion that is not a ferromagnetic material. The removal tool 20 may be "a member formed of a ferromagnetic material and provided with the first yoke contact surface 201 and the second yoke contact surface 202" or "a member including a 'portion formed of a ferromagnetic material and provided with the first yoke contact surface 201 and the second yoke contact surface 202'".

[0026] FIG. 3 is a cross-sectional view showing a schematic state of the mounting tool 10 in use. As shown in FIG. 3, the mounting tool 10 is mounted on the mounting surface 903. When the mounting tool 10 is mounted on the mounting surface 903, the mounting surface 121 of the first yoke 12 is in direct surface contact with the mounting surface 903. On the other hand, the facing surface 131 of the second yoke 13 is located on the remote side of the mounting surface 121 of the first yoke 12 and is covered by the facing surface covering portion 141 of the coating filler 14. Therefore, the facing surface 131 of the second yoke 13 is separated from the mounting surface 903 and does not directly contact the mounting surface 903. The end surface on the proximal side of the facing surface covering portion 141 of the coating filler 14 is approximately flush with the mounting surface 121 of the first yoke 12. Therefore, the mounting surface 121 of the first yoke 12 is in surface contact with the mounting surface 903 without being inclined.

[0027] When the mounting fixture 10 is attached to the object to be mounted, a closed magnetic path (hereinafter, this magnetic path may be referred to as the "first magnetic path M1") is formed from the first magnet 11 through the first yoke 12, the metal insulating sandwich panel 90 to be mounted, the facing surface covering portion 141 of the covering filler 14, the vertical plate portion 135 of the second yoke 13, and the horizontal plate portion 136 of the second yoke 13 to the first magnet 11. Then, a magnetic force is generated between the first yoke 12 and the object to be mounted and between the second yoke 13 and the object to be mounted, and the mounting fixture 10 is held in a state in which it is attracted to the mounting surface 903 by the magnetic force (a state in which the mounting fixture 10 is attached to the object to be mounted). The magnetic force that attracts the mounting fixture 10 to the object to be mounted (the magnetic force acting between the first yoke 12 and the object to be mounted and between the second yoke 13 and the object to be mounted) may be referred to as the "mounting force". According to this embodiment, a first magnetic path M1, which is a closed magnetic path as described above, is formed, so that the mounting force can be made larger than, for example, a configuration in which the mounting fixture 10 has only one of the first yoke 12 or the second yoke 13 (a configuration in which a closed magnetic path is not formed).

[0028] Note that the specific value of the distance between the opposing surface 131 of the second yoke 13 and the attached surface 903 when the mounting surface 121 of the first yoke 12 is in direct surface contact with the attached surface 903, i.e., the size of the gap in the mounting direction between the mounting surface 121 of the first yoke 12 and the opposing surface 131 of the second yoke 13 (which can also be called the distance in the normal direction) is not limited. However, if this gap is too large, no magnetic path is formed between the second yoke 13 and the attached object, that is, the metal insulation sandwich panel 90. For this reason, this gap is set to a size that allows a magnetic path to be formed between the second yoke 13 and the attached object.

[0029] Next, a method of using the removal tool 20 will be described. FIG. 4 is a cross-sectional view showing the removal tool 20 in use. When removing the mounting tool 10 from the mounting surface 903, as shown in FIG. 4, the first yoke contact surface 201 of the removal tool 20 is brought into direct surface contact with the tool contact surface 123 of the first yoke 12, and the second yoke contact surface 202 is brought into direct surface contact with the tool contact surface 133 of the second yoke 13. This forms a closed magnetic path (hereinafter, this magnetic path may be referred to as the "second magnetic path M2") that runs from the first magnet 11 through the first yoke 12, the removal tool 20, and the horizontal plate portion 136 of the second yoke 13 to the first magnet 11. When the second magnetic path M2 is formed by attaching the removal tool 20 to the mounting tool 10, the magnetic flux passing through the first magnetic path M1 decreases (magnetic flux density decreases). As a result, the mounting force decreases.

[0030] In particular, since the opposing surface 131 of the second yoke 13 and the attached surface 903 are not in direct contact with each other, the first magnetic path M1 has a portion with locally high magnetic resistance between the opposing surface 131 of the second yoke 13 and the attached surface 903. On the other hand, the second magnetic path M2 does not have a portion with locally high magnetic resistance. For this reason, the magnetic efficiency of the second magnetic path M2 is higher than that of the first magnetic path M1. Therefore, the reduction amount (cancellation rate) of the magnetic flux passing through the first magnetic path M1 due to the formation of the second magnetic path M2 is larger than that of a configuration in which the first magnetic path M1 does not have a portion with locally high magnetic resistance. In other words, the removal tool 20 is configured to be able to form, between the mounting fixture 10 and the second magnetic path M2, a second magnetic path M2 with a higher magnetic efficiency than the first magnetic path M1 (a magnetic path formed to straddle the mounting fixture 10 and the attached object). Since the second magnetic path M2 does not pass through the metal insulating sandwich panel 90, which is the object to be attached, no adhesive force is generated between the removal tool 20 and the metal insulating sandwich panel 90 due to the second magnetic path M2. In other words, the magnetic flux passing through the second magnetic path M2 does not increase the attachment force. Therefore, the mounting tool 10 becomes easier to remove from the surface to which it is attached (the force required for removal becomes smaller). Thus, according to this embodiment, the mounting force required when using the mounting tool 10 can be increased, while the force required when removing the mounting tool 10 from the object to which it is attached can be reduced.

[0031] Furthermore, according to this embodiment, the object to be attached only needs to have ferromagnetic properties, and there is no need for a fixture such as a mounting unit or a separate member from the object to be attached, which makes it possible to prevent or suppress an increase in the number of parts.

[0032] Second Embodiment 5A and 5B are perspective views that typically show the configuration of the mounting tool 30 and removal tool 40 according to the second embodiment. FIGS. 6A and 6B are exploded perspective views that typically show the configuration of the mounting tool 30 according to the second embodiment. As shown in these figures, the mounting tool 30 according to the second embodiment includes a plurality of second magnets 31, a third yoke 32, a fourth yoke 33, and a plurality of fifth yokes 34. The second magnets 31 are an example of the magnet of the present invention, the third yoke 32 and the fourth yoke 33 are examples of the contact magnetic member of the present invention, and the fifth yoke 34 is an example of the non-contact magnetic member of the present invention.

[0033] Various known magnets can be applied to the second magnet 31. In this embodiment, an example is shown in which the second magnet 31 has a substantially square (rectangular) plate-like shape when viewed in the thickness direction. In this case, the polarization direction of the second magnet 31 is parallel to the thickness direction of the second magnet 31. That is, the S pole and the N pole appear on each of both sides in the thickness direction. The second magnet 31 is also provided with a bolt insertion hole 311 through which the bolt 35 can be inserted. The bolt insertion hole 311 is a through hole that penetrates in the thickness direction (direction parallel to the polarization direction). The second magnet 31 is arranged with the thickness direction (polarization direction) oriented substantially perpendicular to the mounting direction (substantially parallel to the mounting surface 903).

[0034] The third yoke 32, the fourth yoke 33, and the fifth yoke 34 are members made of a soft magnetic material.

[0035] The third yoke 32 is a member provided with an attachment surface 321, a magnet contact surface 322, and a tool contact surface 323. The attachment surface 321 is a surface configured to be able to come into surface contact directly with the attached surface 903. In this embodiment, the attachment surface 321 is an end surface on the near side of the third yoke 32, and is a plane perpendicular to the attachment direction. The magnet contact surface 322 is a surface configured to be able to come into surface contact with the surface on which one of the S pole and the N pole of the second magnet 31 appears. The magnet contact surface 322 is located on the remote side of the attachment surface 321, and is a plane approximately perpendicular to the attachment surface 321. The tool contact surface 323 is a surface configured to be able to come into surface contact with a removal tool 40 described later. In this embodiment, the tool contact surface 323 is an end surface on the remote side of the third yoke 32 (the surface opposite to the attachment surface 321) and the surface opposite to the magnet contact surface 322.

[0036] In this embodiment, the third yoke 32 has a generally rectangular plate-like shape when viewed in the thickness direction. One of the two faces corresponding to the long sides of the rectangle is the attachment surface 321, the other of the two faces corresponding to the long sides (the face opposite to the attachment surface 321) and one face in the thickness direction are the tool contact surface 323, and the other face in the thickness direction is the magnet contact surface 322.

[0037] Further, the third yoke 32 is provided with a bolt insertion hole 324 through which the bolt 35 can be inserted. The bolt insertion hole 324 is a through hole that penetrates the third yoke 32 in the thickness direction.

[0038] The fourth yoke 33 is a member provided with an attachment surface 331, a magnet contact surface 332, and a tool contact surface 333. The attachment surface 331 is a surface configured to face the attached surface 903 and to be able to directly come into surface contact with it. For example, the attachment surface 331 is a plane that is an end surface on the near side of the fourth yoke 33 and perpendicular to the attachment direction. The magnet contact surface 332 is a surface configured to be able to come into contact with a surface on which one of the S pole and the N pole of the second magnet 31 appears. The magnet contact surface 332 is located on the remote side of the attachment surface 331 and is a plane that is approximately perpendicular to the attachment surface 331. The tool contact surface 333 is a surface configured to be able to come into surface contact with a removal tool 40 described later. For example, the tool contact surface 333 is a plane that is an end surface on the remote side of the fourth yoke 33 and is approximately perpendicular to the attachment direction, and is a surface opposite to the magnet contact surface 332.

[0039] In this embodiment, the fourth yoke 33 is exemplified by a configuration including a vertical plate portion 336 and a horizontal plate portion 337. The vertical plate portion 336 has a flat plate shape extending in a direction substantially parallel to the mounting direction. The horizontal plate portion 337 has a flat plate shape extending from the end of the vertical plate portion 336 on the near side to one side in the thickness direction of the vertical plate portion 336 (direction perpendicular to the mounting direction). Therefore, the fourth yoke 33 has a rod shape with a substantially "L" shaped cross section. In this case, the end face on the near side of the vertical plate portion 336 is the mounting surface 331, and one of the side surfaces of the vertical plate portion 336 (one surface in the thickness direction of the flat plate) is the magnet contact surface 332. The other side surface of the vertical plate portion 336 (the surface opposite to the magnet contact surface 332, the other surface in the thickness direction of the vertical plate portion 336) and the end face on the remote side of the vertical plate portion 336 are the tool contact surface 333. Moreover, the horizontal plate portion 337 is the object mounting portion 334 .

[0040] In each drawing, a configuration is shown in which the near-side end surface of the object mounting portion 334 (horizontal plate portion 337) of the fourth yoke 33 is substantially flush with the mounting surface 331, but the present invention is not limited to such a configuration. For example, as in the first embodiment, the object mounting portion 334 may be provided at a position shifted from the mounting surface 331 to the remote side.

[0041] The fourth yoke 33 is provided with a screw hole 335 (female thread) into which the bolt 35 can be screwed. The screw hole 335 is provided so as to penetrate the vertical plate portion 336 in the thickness direction (a direction substantially perpendicular to the mounting direction).

[0042] The fifth yoke 34 includes a facing surface 341, a magnet contact surface 342, and a tool contact surface 343. The facing surface 341 is a surface configured to be able to face the attached surface 903. For example, the facing surface 341 is an end surface on the near side of the fifth yoke 34, and is a plane perpendicular to the attachment direction. The magnet contact surface 342 is a surface configured to be able to contact a surface on which one of the S pole and the N pole of the second magnet 31 appears. The magnet contact surface 342 is located on the remote side of the facing surface 341, and is a plane substantially parallel to the attachment direction. The tool contact surface 343 is a surface configured to be able to come into surface contact with the removal tool 40 described later. The tool contact surface 343 is an end surface on the remote side of the fifth yoke 34, and is a plane substantially perpendicular to the attachment direction. Furthermore, the fifth yoke 34 is provided with a bolt insertion hole 344 through which the bolt 35 can be inserted.

[0043] In this embodiment, an example is shown in which the fifth yoke 34 has a substantially rectangular flat plate shape when viewed in the thickness direction. In this case, one of two faces corresponding to the long sides of the rectangle is an opposing face 341, the face opposite to the one face is a tool contact face 343, and each of both faces in the thickness direction is a magnet contact face 342. The bolt insertion holes 344 are provided so as to penetrate in the thickness direction.

[0044] Here, the assembly structure of the mounting tool 30 according to the second embodiment will be described. The third yoke 32 and the fourth yoke 33 are arranged apart from each other in a predetermined direction (a direction perpendicular to the mounting direction). A plurality of fifth yokes 34 and a plurality of second magnets 31 are arranged between the third yoke 32 and the fourth yoke 33 so as to be alternately arranged in series. A bolt 35 is inserted from the third yoke 32 side and screwed into the fourth yoke 33. As a result, the third yoke 32, the fourth yoke 33, the plurality of second magnets 31, and the plurality of fifth yokes 34 are integrally joined.

[0045] In this state, one surface in the thickness direction of the second magnet 31 closest to the third yoke 32 is in surface contact with the magnet contact surface 322 of the third yoke 32, and the opposite surface is in surface contact with one magnet contact surface 342 of the fifth yoke 34. One surface in the thickness direction of the second magnet 31 closest to the fourth yoke 33 is in surface contact with the magnet contact surface 332 of the fourth yoke 33, and the opposite surface is in surface contact with the magnet contact surface 342 of the fifth yoke 34. Both surfaces in the thickness direction of the second magnet 31 other than these are each in surface contact with the magnet contact surface 342 of the fifth yoke 34.

[0046] The mounting surface 321 of the third yoke 32 and the mounting surface 331 of the fourth yoke 33 are substantially parallel to the predetermined direction and are substantially flush with each other (in other words, the mounting surface 321 of the third yoke 32 and the mounting surface 331 of the fourth yoke 33 are located on the same plane). The facing surfaces 341 of the plurality of fifth yokes 34 are substantially parallel to the predetermined direction and are located at positions shifted toward the remote side from the mounting surface 321 of the third yoke 32 and the mounting surface 331 of the fourth yoke 33. The facing surfaces 341 of the plurality of fifth yokes 34 may or may not be flush with each other. The end surfaces on the near side of the plurality of second magnets 31 are also located at positions shifted toward the remote side from the mounting surface 321 of the third yoke 32 and the mounting surface 331 of the fourth yoke 33.

[0047] Meanwhile, the part of the tool contact surface 323 of the third yoke 32 opposite to the mounting surface 321, the part of the tool contact surface 333 of the fourth yoke 33 opposite to the mounting surface 331, and the tool contact surfaces 343 of the plurality of fifth yokes 34 are substantially flush with each other at a right angle to the mounting direction. The end faces on the remote side of the plurality of second magnets 31 are substantially flush with the tool contact surface 323 of the third yoke 32, the tool contact surface 333 of the fourth yoke 33, and the tool contact surfaces 343 of the plurality of fifth yokes 34, or are positioned at a position shifted toward the proximal side from the tool contact surface 323 of the third yoke 32, the tool contact surface 333 of the fourth yoke 33, and the tool contact surfaces 343 of the plurality of fifth yokes 34. In other words, the second magnets 31 are arranged so as not to protrude from the tool contact surface 323 of the third yoke 32, the tool contact surface 333 of the fourth yoke 33, and the tool contact surfaces 343 of the plurality of fifth yokes 34 to the remote side.

[0048] In the second embodiment, the mounting fixture 30 is not provided with the coating filler 14, but the present invention is not limited to such a configuration. For example, the coating filler 14 may be provided with a portion covering the end faces of the second magnets 31 on the near side and the opposing surface 341 of the fifth yoke 34. However, it is preferable that the mounting surface 321 of the third yoke 32 and the mounting surface 331 of the fourth yoke 33 are exposed without being covered by the coating filler 14. For example, the end face on the near side of the portion of the coating filler 14 is a plane that is substantially flush with the mounting surface 321 of the third yoke 32 and the mounting surface 331 of the fourth yoke 33, and is provided so as not to protrude from the mounting surface 321 of the third yoke 32 and the mounting surface 331 of the fourth yoke 33 to the near side.

[0049] Further, the photovoltaic power generation panel 80, which is the object, is attached to the object attachment portion 334 of the fourth yoke 33. The method and structure of attaching the object are not particularly limited. For example, the same method as in the first embodiment can be applied. In this case, the object attachment portion 334 may be provided at a position shifted away from the attachment surface 331 as in the first embodiment. With this configuration, the attachment surface 331 of the fourth yoke 33 and the surface of the back sheet 803 of the photovoltaic power generation panel 80 can be made substantially flush with each other, so that the attachment surface 331 of the fourth yoke 33 can be brought into surface contact with the attached surface 903.

[0050] The removal tool 40 is a tool used when removing the mounting fixture 30 from the mounting surface 903. The removal tool 40 is formed of a ferromagnetic material. The removal tool 40 is provided with a yoke contact surface 401. The yoke contact surface 401 is a surface configured to be able to come into surface contact with the tool contact surface 323 of the third yoke 32, the tool contact surface 333 of the fourth yoke 33, and the tool contact surface 343 of the fifth yoke 34. In this embodiment, the removal tool 40 includes a horizontal plate portion 402 that is a flat plate-shaped portion extending approximately perpendicular to the mounting direction, and two vertical plate portions 403 that protrude from the near side surface of the horizontal plate portion 402 toward the near side. The two vertical plate portions 403 are provided spaced apart from each other in a direction approximately perpendicular to the mounting direction. In this case, the near side surface of the horizontal plate portion 402 and the opposing surfaces of the two vertical plate portions 403 are the yoke contact surface 401.

[0051] However, the specific shape of the removal tool 40 is not particularly limited. Furthermore, the removal tool 40 may include a portion that is not made of a ferromagnetic material. The removal tool 40 may be a "member formed of a ferromagnetic material and provided with the yoke contact surface 401" or a "member formed of a ferromagnetic material and including a portion provided with the yoke contact surface 401."

[0052] Fig. 7 is a diagram showing a state in which the mounting fixture 30 according to the second embodiment is used. As shown in Fig. 7, the mounting fixture 30 is mounted to a mounting surface 903 of a metal insulation sandwich panel 90, which is an object to be mounted. When the mounting fixture 30 is mounted to the mounting surface 903 of the metal insulation sandwich panel 90, the mounting surface 321 of the third yoke 32 and the mounting surface 331 of the fourth yoke 33 are in surface contact with the mounting surface 903. However, since the opposing surface 341 of the fifth yoke 34 is located on the remote side of the mounting surface 321 of the third yoke 32 and the mounting surface 331 of the fourth yoke 33, the opposing surface 341 does not contact the mounting surface 903 and is separated from the mounting surface 903 on the remote side.

[0053] This forms the following magnetic paths (hereinafter, these magnetic paths may be referred to as "third magnetic path M3"): "a magnetic path passing through one second magnet 31, the fifth yoke 34 adjacent to (contacting) one surface side of the second magnet 31 in the thickness direction, the object to which the magnetic magnet 31 is attached, and the fifth yoke 34 adjacent to (contacting) the other surface side of the second magnet 31 in the thickness direction, to the second magnet 31", "a magnetic path passing through one second magnet 31, the fifth yoke 34 adjacent to (contacting) one surface side of the second magnet 31 in the thickness direction, the object to which the magnetic magnet 31 is attached, and the third yoke 32 adjacent to (contacting) the other surface side of the second magnet 31 in the thickness direction, to the second magnet 31", and "a magnetic path passing through one second magnet 31, the fifth yoke 34 adjacent to (contacting) one surface side of the second magnet 31 in the thickness direction, the object to which the magnetic magnet 31 is attached, and the fourth yoke 33 adjacent to the other surface side of the second magnet 31 in the thickness direction, to the second magnet 31". Then, an attachment force (magnetic force) is generated between the third yoke 32, the fourth yoke 33, and the fifth yoke 34 and the metal insulation sandwich panel 90, and the attachment force keeps the mounting fixture 30 attached to the metal insulation sandwich panel 90.

[0054] Next, a method of using the removal tool 40 will be described. FIG. 8 is a cross-sectional view showing the removal tool 40 in use. When removing the mounting fixture 30 from the mounting surface 903, as shown in FIG. 8, the yoke contact surface 401 of the removal tool 40 is brought into surface contact with the tool contact surface 323 of the third yoke 32, the tool contact surface 333 of the fourth yoke 33, and the tool contact surface 343 of the fifth yoke 34. When the removal tool 40 is attached to the mounting fixture 30 in this manner, "a magnetic path leading to the one second magnet 31 via one second magnet 31, the fifth yoke 34 adjacent to (in contact with) one surface side of the one second magnet 31 in the thickness direction, the removal tool 40, and the fifth yoke 34 adjacent to the other surface side of the one second magnet 31 in the thickness direction" and "a magnetic path leading to the one second magnet 31 via one second magnet 31, the fifth yoke 34 adjacent to (in contact with) one surface side of the one second magnet 31 in the thickness direction, the removal tool 40, and the one The magnetic paths (hereinafter sometimes referred to as "fourth magnetic path M4") are formed: a magnetic path through the third yoke 32 adjacent to (contacting) the other surface side of the one second magnet 31 in the thickness direction to the one second magnet 31; and a magnetic path through the one second magnet 31, the fifth yoke 34 adjacent to (contacting) one surface side of the one second magnet 31 in the thickness direction, the removal tool 40, and the fourth yoke 33 adjacent to the other surface side of the one second magnet 31 in the thickness direction to the one second magnet 31.

[0055] When the fourth magnetic path M4 is formed, the magnetic flux passing through the third magnetic path M3 decreases (magnetic flux density decreases). As a result, the mounting force acting between the third yoke 32 and the fourth yoke 33 and the object to be attached decreases. In particular, since the facing surface 341 of the fifth yoke 34 and the object to be attached are not in direct contact with each other, the third magnetic path M3 has a portion with locally high magnetic resistance between the facing surface 341 of the fifth yoke 34 and the object to be attached. On the other hand, the fourth magnetic path M4 does not have a portion with locally high magnetic resistance like the third magnetic path M3. For this reason, the magnetic efficiency of the fourth magnetic path M4 is higher than that of the third magnetic path M3. In other words, the removal tool 40 is configured to be able to form, between the mounting fixture 30, a fourth magnetic path M4 with a higher magnetic efficiency than the third magnetic path M3 (a magnetic path formed to straddle the mounting fixture 30 and the object to be attached).

[0056] Therefore, the reduction amount (cancellation rate) of the magnetic flux passing through the third magnetic path M3 due to the formation of the fourth magnetic path M4 is larger than that of a configuration in which the third magnetic path M3 does not have a portion with locally high magnetic resistance. Also, since the fourth magnetic path M4 does not pass through the workpiece, no attraction force due to the fourth magnetic path M4 is generated between the removal tool 40 and the workpiece. Therefore, the attachment force acting between the third yoke 32, the fourth yoke 33, and the fifth yoke 34 and the workpiece is reduced, and as a result, the fixture 30 can be easily removed from the workpiece surface 903 (the force required for removal is reduced).

[0057] Furthermore, according to the second embodiment, as in the first embodiment, it is sufficient that the object to be attached has ferromagnetic properties, and there is no need for a mounting unit or other attachment or a component separate from the object to be attached, so that an increase in the number of parts can be prevented or suppressed. Note that magnets of the same configuration can be applied to the multiple second magnets 31, and components of the same configuration can be applied to the multiple fifth yokes 34. And, if magnets of the same configuration are applied to the multiple second magnets 31, and components of the same configuration are applied to the multiple fifth yokes 34, an increase in the variety of parts can be prevented or suppressed.

[0058] <Summary of the embodiment> The mounting fixtures 10 and 30 according to the embodiments of the present invention are for removably mounting an object (a photovoltaic power generation panel 80 in this embodiment) to a mounting surface 903 of a mounting base (a metal insulation sandwich panel 90, which is a ferromagnetic member in this embodiment) by magnetic force, Magnets (first magnet 11, second magnet 31), a contact magnetic member (first yoke 12, third yoke 32, fourth yoke 33) formed of a ferromagnetic material, comprising a mounting surface 121, 321, 331 configured to be capable of surface contact with the mounting surface 903 and a tool contact surface 123, 323, 333 configured to be capable of surface contact with a part of the removal tool 20, 40, and in contact with a surface on which one pole of the magnet (first magnet 11, second magnet 31) appears; a non-contact magnetic member (second yoke 13, fifth yoke 34) which is made of a ferromagnetic material and has an opposing surface 131, 341 configured to be spaced apart from the attached surface 903 with a predetermined gap when the attachment surface 121, 321, 331 of the contact magnetic member (first yoke 12, third yoke 32, fourth yoke 33) is in surface contact with the attached surface 903, and a tool contact surface 133, 343 configured to be able to come into surface contact with another part of the removal tool 20, 40, and which is in contact with a surface on which the other pole of the magnet (first magnet 11, second magnet 31) appears; Equipped with When the mounting surfaces 121, 321, 331 come into surface contact with the mounting surface 903, a magnetic path (first magnetic path M1, third magnetic path M3) is formed from the magnets 11, 31 through the contact magnetic members (first yoke 12, third yoke 32, fourth yoke 33), the mounting object (metal insulating sandwich panel 90), and the non-contact magnetic members (second yoke 13, fifth yoke 34) to the magnets 11, 31, When the removal tools 20, 40 are attached so as to contact the tool contact surfaces 123, 323, 333 of the contact magnetic member (first yoke 12, third yoke 32, fourth yoke 33) and the tool contact surfaces 133, 343 of the non-contact magnetic member (second yoke 13, fifth yoke 34), another magnetic path (second magnetic path M2, fourth magnetic path M4) is formed from the magnet (first magnet 11, second magnet 31) through the contact magnetic member (first yoke 12, third yoke 32, fourth yoke 33), the removal tools 20, 40, and the non-contact magnetic member (second yoke 13, fifth yoke 34) to the magnet (first magnet 11, second magnet 31).

[0059] According to this configuration, when the mounting fixtures 10, 30 are attached to the mounting surface 903 of the mounting target (metal insulating sandwich panel 90), magnetic paths (first magnetic path M1, third magnetic path M3) are formed from the magnets (first magnet 11, second magnet 31) through the contact magnetic members (first yoke 12, third yoke 32, fourth yoke 33), the mounting target (metal insulating sandwich panel 90), and the non-contact magnetic members (second yoke 13, fifth yoke 34) to the magnets. Therefore, the mounting fixtures 10, 30 are firmly attached to the mounting target (metal insulating sandwich panel 90) by magnetic force. On the other hand, when the removal tool 20, 40 is attached so as to contact both the tool contact surface 123, 323, 333 of the contact magnetic member (first yoke 12, third yoke 32, fourth yoke 33) and the tool contact surface 133, 343 of the non-contact magnetic member (second yoke 13, fifth yoke 34), another magnetic path (second magnetic path M2, fourth magnetic path M4) is formed from the magnet (first magnet 11, second magnet 31) through the contact magnetic member (first yoke 12, third yoke 32, fourth yoke 33), the removal tool 20, 40, and the non-contact magnetic member (second yoke 13, fifth yoke 34) to the magnet (first magnet 11, second magnet 31). By forming such another magnetic path (second magnetic path M2, fourth magnetic path M4), the magnetic flux passing through the magnetic path (first magnetic path M1, third magnetic path M3) is reduced (magnetic flux density is reduced). Therefore, the magnetic force (attaching force) between the mounting fixtures 10, 30 and the object (metal insulating sandwich panel 90) is reduced, making it easier to remove the mounting fixtures 10, 30 from the object (metal insulating sandwich panel 90). In addition, since the mounting unit described in Patent Document 1 is not required, an increase in the number of parts can be prevented or suppressed.

[0060] In addition, the mounting surfaces 121, 321, 331 of the contact magnetic members (first yoke 12, third yoke 32, fourth yoke 33) and the opposing surfaces 131, 341 of the non-contact magnetic members (second yoke 13, fifth yoke 34) are approximately flat surfaces that are approximately parallel to each other and face the same side, and are positioned at positions shifted from each other in the normal direction so that the mounting surfaces 121, 321, 331 protrude further than the opposing surfaces 131, 341.

[0061] With this configuration, when the mounting surfaces 121, 321, 331 come into surface contact with the mounting surface 903 of the object (metal insulation sandwich panel 90), a gap is formed between the opposing surfaces 131, 341 and the mounting surface 903.

[0062] Two contact magnetic members (a third yoke 32 and a fourth yoke 33) arranged apart from each other in a predetermined direction; A plurality of the magnets (second magnets 31) and a plurality of the non-contact magnetic members (fifth yoke 34) are arranged alternately in the predetermined direction between the two contact magnetic members (third yoke 32, fourth yoke 33), Equipped with The mounting surfaces 321 and 331 of the two contact magnetic members (the third yoke 32 and the fourth yoke 33) are substantially flush with each other and are flat surfaces substantially parallel to the predetermined direction, The opposing surfaces 341 of the multiple non-contact magnetic members (fifth yoke 34) are planes that are approximately parallel to the specified direction and approximately parallel to the mounting surfaces 321, 331 of the two contact magnetic members (third yoke 32, fourth yoke 33).

[0063] With this configuration, when the mounting surfaces 321, 331 come into surface contact with the mounting surface 903 of the object (the metal insulation sandwich panel 90), a gap is formed between the opposing surface 341 and the mounting surface 903.

[0064] One of the two contact magnetic members (the fourth yoke 33) is provided with an object mounting portion 334 configured so that the object (the solar power generation panel 80) can be mounted thereon.

[0065] With this configuration, the object (photovoltaic power generation panel 80) to which the mounting fixture 30 is attached can be mounted to the mounting surface 903 of the mounting target (metal insulation sandwich panel 90).

[0066] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications are possible without departing from the spirit of the present invention.

[0067] For example, the object of the mounting fixture 10, 30 is not limited to the photovoltaic panel 80, and the object to be mounted is not limited to the metal insulation sandwich panel 90. Furthermore, the configuration of the object mounting portion 134, 334 is appropriately set according to the structure of the object, and the specific configuration is not limited.
