Description

[Technical Field]

[0001] The present disclosure relates to a mounting structure for facility equipment. [Background technology]

[0002] Patent Document 1 discloses a power supply structure. This power supply structure wirelessly supplies power using a power transmitting and receiving unit, and includes a partition member that defines an internal space and a base member to which the partition member is fixed. A pair of power transmitting and receiving units are provided on the internal space side of the partition member and on the opposite side of the internal space of the partition member.

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-35336 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-described power supply structure, power transmission and reception units are provided on both the interior space side and the opposite side of the partition material, enabling wireless power supply to the interior space. As a result, it is unnecessary to form a through hole in the partition material for power supply. However, when attaching equipment to be powered to the partition material, it may be necessary to form a through hole in the partition material for attaching the equipment. In this case, pests, foreign objects, etc. may enter from the outside through the through hole. In interior spaces that require cleanliness, there is a concern that the cleanliness of the interior space may be reduced due to the entry of foreign objects, etc. In addition, when rearranging equipment in the interior space, it may be necessary to block the through hole in the partition material each time.

[0005] The present disclosure aims to provide a mounting structure for equipment that allows equipment to be installed without providing a through-hole for mounting in a partition material and that makes it easy to change the position of the equipment. [Means for solving the problem]

[0006] The mounting structure for facility equipment according to the present disclosure comprises (1) a partition material defining an internal space, facility equipment attached to the partition material and placed in the internal space, a first magnet located on the opposite side of the partition material from the internal space, a second magnet located on the internal space side of the partition material and attracted to both the first magnet and the facility equipment, a power transmitting and receiving unit having a power transmitting unit located on the opposite side of the partition material from the internal space, and a power receiving unit located on the internal space side of the partition material and supplying power to the facility equipment.

[0007] In this equipment mounting structure, the equipment, which receives power wirelessly from the power transmitting and receiving unit, is disposed in the interior space. The equipment receives power from the power receiving unit, allowing it to receive power from outside the interior space. The first magnet is disposed outside the interior space, and the second magnet is disposed inside the interior space. The equipment is attracted to the second magnet, and the second magnet and the first magnet, which are disposed on opposite sides of the partition material, are attracted to each other through a magnetic force. This allows the equipment to be mounted to the partition material using the magnetic force of the first and second magnets. Therefore, there is no need to provide a through-hole in the partition material. Therefore, the equipment can be mounted on the partition material without providing a through-hole in the partition material for mounting the equipment, thereby preventing a decrease in the cleanliness of the interior space. Furthermore, there is no need to block the through-hole in the partition material. If the location of the equipment needs to be changed, the first and second magnets can be repositioned to change the location of the equipment. This facilitates repositioning of the equipment.

[0008] (2) In the above (1), a groove may be provided in the partition material on the side opposite to the equipment. The first magnet may be disposed inside the groove. In this case, by disposing the first magnet inside the groove, the distance between the first magnet and the second magnet can be shortened, and the first magnet and the second magnet can be brought closer to each other. This strengthens the attractive force acting between the first magnet and the second magnet, making it easier to attach the equipment to the partition material and allowing the equipment to be attached to the partition material more strongly.

[0009] (3) In the above (2), the equipment mounting structure may include a support member fixed to the surface of the first magnet facing away from the internal space and abutting against the surface of the partition facing away from the internal space. In this case, the support member can distribute the attractive force acting on the first magnet placed inside the groove to the partition. This allows the first magnet to be stably fixed to the partition.

[0010] (4) In any of (1) to (3) above, the second magnet may be located on the opposite side of the partition material from the part of the equipment. The part of the equipment may be attached to the partition material by being sandwiched between the partition material and the second magnet. In this case, the second magnet can be fixed to the part of the equipment, and then the part can be supported on the partition material to attach the equipment to the partition material. This makes it easier to attach the equipment to the partition material.

[0011] (5) In any of (1) to (4) above, the partition member may be plate-shaped. The power transmitting unit and the power receiving unit may each be annular when viewed along the thickness direction of the partition member. When viewed along the thickness direction of the partition member, the first magnet may be disposed inside the power transmitting unit, and the second magnet may be disposed inside the power receiving unit. In this case, the installation structure of the facility equipment can be simplified. [Effects of the Invention]

[0012] According to the present disclosure, equipment can be installed without providing a through-hole for attachment in the partition material, and the placement of the equipment can be easily changed. [Brief explanation of the drawings]

[0014] Hereinafter, an embodiment of the installation structure for facility equipment according to the present disclosure will be described with reference to the drawings. In the description of the drawings, the same or corresponding elements are designated by the same reference numerals, and duplicate explanations will be omitted as appropriate. The drawings may be partially simplified or exaggerated for ease of understanding, and the dimensional proportions and the like are not limited to those shown in the drawings.

[0015] (First embodiment) In the present disclosure, a "power transmitting and receiving unit" refers to a part that transmits or receives power, and includes, for example, a metal coil, a plate-shaped member, a transmitting antenna, and a receiving antenna, where one of a pair of power transmitting and receiving units transmits power and the other receives the power. "Wireless power supply" refers to supplying power to a predetermined location using a wireless power supply method, and includes a magnetic field coupling method, an electric field coupling method, and a radio wave receiving method. The magnetic field coupling method includes, for example, an electromagnetic induction method and a magnetic field resonance method (magnetic resonance method). In this embodiment, an example in which the magnetic field coupling method is used in wireless power supply will be described. "Partition material" refers to a member that separates a predetermined space, and includes, for example, a member (such as a ceiling, a wall, and a floor) that separates an internal space from a space other than the internal space. In this embodiment, an example in which the "partition material" is a ceiling material will be described.

[0016] Fig. 1 is a cross-sectional view showing a mounting structure 1 for facility equipment according to the first embodiment. As shown in Fig. 1, the mounting structure 1 includes a ceiling material 10 (partition material), an LED light 20 (facility equipment), a first magnet 31, a second magnet 32, a support member 41, and a power transmitting and receiving unit 50.

[0017] The ceiling material 10 is plate-shaped. In the following description, the thickness direction of the ceiling material 10 is referred to as the first direction D1, the direction in which the LED lights 20 extend is referred to as the second direction D2, and the direction perpendicular to both the first direction D1 and the second direction D2 is referred to as the third direction D3. However, these directions are used for convenience of explanation and do not limit the position or direction of objects. For example, the second direction D2 and the third direction D3 are horizontal directions, and the first direction D1 is vertical.

[0018] The ceiling material 10 extends in both the second direction D2 and the third direction D3. The ceiling material 10 defines an internal space K. The internal space K may be, for example, an enclosed space such as a clean room. That is, the internal space K may be an enclosed space. However, the internal space K does not have to be an enclosed space, and may be, for example, a living room. For example, the ceiling material 10 does not have any through holes. Therefore, it is possible to prevent dust, pests, etc. from entering the internal space K from the outside.

[0019] The ceiling material 10 has a gypsum board 11 and a decorative calcium silicate board 12. The gypsum board 11 may be a base material. The decorative calcium silicate board 12 is a decorative board. The "calcium silicate" in the decorative calcium silicate board 12 means calcium silicate. In this embodiment, a decorative calcium silicate board 12 containing calcium silicate is used as the decorative board. By selecting calcium silicate as the decorative board, it is possible to improve fire resistance, water resistance, and heat insulation, as well as reduce weight, thereby improving the efficiency of installing the ceiling material 10.

[0020] The gypsum board 11 and the decorative calcium silicate board 12 are fixed to each other along a first direction D1. In the ceiling material 10, the gypsum board 11 is located on the opposite side to the internal space K, and the decorative calcium silicate board 12 is located on the internal space K side. The ceiling material 10 is formed by bonding the gypsum board 11 and the decorative calcium silicate board 12 together to form a single unit. In this embodiment, the side opposite the internal space K may be above the ceiling.

[0021] The thickness of the gypsum board 11 is, for example, greater than the thickness of the decorative calcium silicate board 12. The thickness of the gypsum board 11 is, for example, 10 mm or more and 20 mm or less. The thickness of the decorative calcium silicate board 12 is, for example, 1 mm or more and 10 mm or less. The gypsum board 11 has a surface 11a. The surface 11a is the surface of the gypsum board 11 facing away from the internal space K. The decorative calcium silicate board 12 has a surface 12a. The surface 12a is the surface of the decorative calcium silicate board 12 facing the internal space K.

[0022] The LED lighting 20 is attached to the ceiling material 10. The LED lighting 20 is arranged in the interior space K. Specifically, the LED lighting 20 is attached to the surface 12a of the decorative calcium silicate board 12. In this embodiment, an example will be described in which the facility equipment is the LED lighting 20. However, the facility equipment is not limited to the LED lighting 20. The facility equipment may be, for example, an evacuation guide light, a fire alarm, production equipment, or a vacuum cleaner. Production equipment is, for example, equipment used for producing products, but the production equipment may also include equipment for repairing and servicing products.

[0023] In this embodiment, the LED lighting 20 is a straight-tube LED lamp. The LED lighting 20 extends along the second direction D2. The LED lighting 20 has a light-emitting section 21 and a support section 22. The light-emitting section 21 is a section that functions as a lighting fixture by emitting light from the LED. The light-emitting section 21 has a rod shape that extends along the second direction D2. The light-emitting section 21 is not in contact with the decorative calcium silicate board 12, and is positioned at a distance from the decorative calcium silicate board 12 in the first direction D1.

[0024] The support portion 22 supports the light-emitting portion 21. The support portion 22 is fixed to the surface 12a of the decorative calcium silicate board 12. A plurality of support portions 22 are arranged in the LED lighting 20. In one example, two support portions 22 are arranged. The plurality of support portions 22 are arranged side by side in the second direction D2. The support portion 22 has, for example, a rectangular parallelepiped shape. For example, the length of the support portion 22 in the first direction D1 is longer than the length of the support portion 22 in the second direction D2 and the length of the support portion 22 in the third direction D3. For example, the light-emitting portion 21 is supported by a lower portion of the support portion 22. The support portion 22 is arranged to support both ends of the light-emitting portion 21 in the second direction D2. The support portion 22 has a built-in terminal for supplying electricity. The support portion 22 supports the light-emitting portion 21 and also has the function of supplying power to the light-emitting portion 21.

[0025] The portion 23 of the LED lighting 20 is made of, for example, a magnetic material. The portion 23 of the LED lighting 20 is a portion of the LED lighting 20 that comes into contact with the surface 12a of the decorative calcium silicate board 12. For example, the portion 23 of the LED lighting 20 is made of steel. In this embodiment, the "portion 23 of the LED lighting 20" refers to the portion of the LED lighting 20 that comes into contact with the surface 12a of the decorative calcium silicate board 12. The portion 23 of the LED lighting 20 is, for example, plate-shaped. The portion 23 of the LED lighting 20 may be a top plate of the LED lighting 20. The LED lighting 20 is fixed to the ceiling material 10 by fixing the portion 23 of the LED lighting 20 to the surface 12a of the decorative calcium silicate board 12.

[0026] The portion 23 of the LED lighting 20 and the plurality of supporting portions 22 are fixed to each other. Specifically, one end of the portion 23 of the LED lighting 20 in the second direction D2 is fixed to one of the supporting portions 22. The other end of the portion 23 of the LED lighting 20 in the second direction D2 is fixed to the other supporting portion 22. The portion 23 of the LED lighting 20 may be integrated with the plurality of supporting portions 22. A space S may be formed between the portion 23 of the LED lighting 20 and the light-emitting portion 21. The LED lighting 20 may be provided with a cover that covers the space S from the third direction D3.

[0027] A groove 13 is formed in the gypsum board 11. The groove 13 is provided on the ceiling material 10 on the opposite side from the LED lighting 20. The groove 13 is formed so as to face the outside of the ceiling material 10, which is the opposite side from the internal space K. The groove 13 is provided on the surface 11a of the gypsum board 11. The groove 13 is formed so as to be recessed from the surface 11a of the gypsum board 11 towards the internal space K. The groove 13 is formed within a range where the LED lighting 20 is located when viewed from the first direction D1. The groove 13 is located above the LED lighting 20. In this embodiment, the ceiling material 10 (gypsum board 11) has a plurality of grooves 13. In one example, two grooves 13 are formed. The plurality of grooves 13 are lined up, for example, along the second direction D2.

[0028] The groove 13 has a rectangular shape when viewed from the first direction D1, for example. The length of the groove 13 in the second direction D2 is longer than the length of the groove 13 in the third direction D3 (see FIG. 2). The groove 13 is provided for installing a first magnet 31, which will be described in detail later. In this embodiment, the groove 13 does not penetrate the gypsum board 11. However, the groove 13 may be formed by a through hole provided in the gypsum board 11 and the decorative calcium silicate board 12 that forms the bottom surface of the through hole.

[0029] The first magnet 31 is located on the opposite side of the interior space K when viewed from the ceiling material 10. The first magnet 31 is arranged on the ceiling material 10. Specifically, the first magnet 31 is arranged on the surface 11a of the gypsum board 11. The first magnet 31 is also arranged within the range of the portion where the LED light 20 is located when viewed from the first direction D1. As described above, the first magnet 31 is arranged inside the groove 13. In this embodiment, the mounting structure 1 includes a plurality of first magnets 31. In one example, two first magnets 31 are arranged. The plurality of first magnets 31 are arranged side by side along the second direction D2.

[0030] The first magnet 31 has a rod shape. As an example, the first magnet 31 has a rectangular parallelepiped shape. However, the shape of the first magnet 31 is not particularly limited. For example, the length of the first magnet 31 in the second direction D2 is longer than the length of the first magnet 31 in the first direction D1 and the length of the first magnet 31 in the third direction D3. For example, the length of the first magnet 31 in the first direction D1 is shorter than the length of the groove 13 in the first direction D1. For example, the length of the first magnet 31 in the second direction D2 is shorter than the length of the groove 13 in the second direction D2. For example, the length of the first magnet 31 in the third direction D3 is shorter than the length of the groove 13 in the third direction D3 (see FIG. 2). The first magnet 31 is, for example, a permanent magnet. However, the first magnet 31 may be, for example, an electromagnet, and the type of the first magnet 31 is not particularly limited.

[0031] The first magnet 31 has a surface 31a (see FIG. 2). The surface 31a is the surface of the first magnet 31 facing away from the internal space K. For example, the first magnet 31 is arranged so that the surface 31a is aligned along the surface 11a of the gypsum board 11. The surface 31a of the first magnet 31 and the surface 11a of the gypsum board 11 may extend along a horizontal plane.

[0032] The second magnet 32 ​​is attracted to both the first magnet 31 and the LED light 20. The second magnet 32 ​​is located on the internal space K side when viewed from the ceiling material 10. The second magnet 32 ​​is arranged within the range of the portion where the LED light 20 is located when viewed from the first direction D1. The second magnet 32 ​​is arranged below the decorative calcium silicate board 12. Specifically, the second magnet 32 ​​is arranged between the portion 23 of the LED light 20 and the light-emitting unit 21. The second magnet 32 ​​is arranged in the space S formed between the portion 23 of the LED light 20 and the light-emitting unit 21. The second magnet 32 ​​is attracted to the portion 23 of the LED light 20.

[0033] In this embodiment, the mounting structure 1 includes a plurality of second magnets 32. In one example, two second magnets 32 are arranged. The plurality of second magnets 32 are arranged side by side along the second direction D2. The length of the second magnets 32 in the first direction D1 is shorter than the distance between the lower end of the part 23 of the LED lighting 20 and the upper end of the light-emitting section 21. The shape and material of the second magnets 32 are the same as those of the first magnets 31.

[0034] The first magnet 31 and the second magnet 32 ​​are aligned along the first direction D1. The ceiling material 10 and a portion 23 of the LED light 20 are sandwiched between the first magnet 31 and the second magnet 32. The LED light 20 is attached to the ceiling material 10 by sandwiching the portion 23 of the LED light 20 between the ceiling material 10 and the second magnet 32. The distance between the first magnet 31 and the second magnet 32 ​​is equal to or greater than the combined length of the thickness of the gypsum board 11 at the portion where the groove 13 is formed, the thickness of the decorative calcium silicate board 12, and the thickness of the portion 23 of the LED light 20. The distance between the first magnet 31 and the second magnet 32 ​​is, for example, 6 mm or more and 20 mm or less. The length of the first magnet 31 in the second direction D2 and the length of the second magnet 32 ​​in the second direction D2 may be the same.

[0035] FIG. 2 is a partial plan view showing the first magnet 31 and the support member 41. The support member 41 is a member for fixing the first magnet 31 to the ceiling material 10 (groove 13). The support member 41 may also be a member for dispersing the attraction force acting on the first magnet 31 to the ceiling material 10 (plaster board 11). The support member 41 is arranged on the surface 11a of the plaster board 11. The support member 41 is arranged on the surface 11a of the plaster board 11 so as to straddle the groove 13. The support member 41 is arranged in a direction that intersects with the first magnet 31. In this embodiment, the support member 41 and the first magnet 31 are arranged so as to intersect with each other (for example, orthogonal to each other).

[0036] The support member 41 is fixed to a surface 31a of the first magnet 31 facing away from the internal space K. In this embodiment, the surface 31a is the upper surface of the first magnet 31. The support member 41 also abuts against a surface 11a of the ceiling material 10 facing away from the internal space K. Both end portions of the support member 41 in the third direction D3 abut against the surface 11a of the gypsum board 11. The center portion of the support member 41 is fixed to the surface 31a of the first magnet 31.

[0037] The support member 41 is made of, for example, a magnetic material. In this case, the support member 41 is fixed to the surface 31a of the first magnet 31 by an attractive force acting on the first magnet 31. The support member 41 may also be fixed to the surface 11a of the gypsum board 11. In the first direction D1, the support member 41, the first magnet 31, the gypsum board 11, the decorative calcium silicate board 12, the part 23 of the LED light 20, the second magnet 32, and the light-emitting unit 21 are arranged in this order.

[0038] When the first magnet 31 is attracted to the support member 41, a gap may be formed below the first magnet 31. Specifically, a gap may be formed between the lower surface of the first magnet 31 and the gypsum board 11. The length of this gap in the first direction D1 may be shorter than the length of this gap in the second direction D2.

[0039] The support member 41 has, for example, a rectangular parallelepiped shape. The length of the support member 41 in the third direction D3 is longer than the length of the support member 41 in the first direction D1 and the length of the support member 41 in the second direction D2. The length of the support member 41 in the second direction D2 is shorter than the length of the first magnet 31 in the second direction D2. The length of the support member 41 in the third direction D3 is longer than the length of the first magnet 31 in the third direction D3.

[0040] In this embodiment, the mounting structure 1 has a plurality of support members 41. The plurality of support members 41 are aligned along the second direction D2. In one example, a plurality of (for example, two) support members 41 are arranged for each first magnet 31. For example, a total of four support members 41 are arranged.

[0041] The support member 41 is made of, for example, steel. As an example, the support member 41 is made of iron. However, the material of the support member 41 is not particularly limited. For example, if the support member 41 is made of a magnetic material, the support member 41 will be attracted to the first magnet 31, thereby dispersing the attraction force of the second magnet 32 ​​attracting the first magnet 31 to the ceiling material 10. This makes it possible to prevent the first magnet 31 from sinking into the ceiling material 10 (decorative calcium silicate board 12). Furthermore, when the support member 41 is attracted to the first magnet 31, the support member 41 can be easily attached to and detached from the first magnet 31.

[0042] As shown in FIG. 1 , the power transmitting and receiving unit 50 is disposed, for example, on one side in the second direction D2 as viewed from the LED lighting 20. The power transmitting and receiving unit 50 has a power transmitting coil 51 (power transmitting unit) and a power receiving coil 52 (power receiving unit). The power transmitting coil 51 is located on the opposite side of the interior space K as viewed from the ceiling material 10. The power transmitting coil 51 is fixed to a surface 11a of the gypsum board 11. The power receiving coil 52 is located on the interior space K side as viewed from the ceiling material 10. The power receiving coil 52 supplies power to the LED lighting 20. The power receiving coil 52 is fixed to a surface 12a of the decorative calcium silicate board 12.

[0043] The power transmitting coil 51 and the power receiving coil 52 are fixed to the ceiling material 10 by, for example, double-sided tape, adhesive, screws, or the like. However, the method for fixing the power transmitting coil 51 and the power receiving coil 52 is not limited to the above example. The power transmitting coil 51 and the power receiving coil 52 supply power from the outside to the interior of the internal space K by, for example, a magnetic field coupling method. For example, each of the power transmitting coil 51 and the power receiving coil 52 has a ring shape when viewed along a first direction D1, which is the thickness direction of the ceiling material 10. The planar shape of the power transmitting coil 51 and the power receiving coil 52 is, for example, rectangular, and in one example, a rectangular frame shape. For example, the length of the power transmitting coil 51 in the second direction D2 is the same as the length of the power receiving coil 52 in the second direction D2.

[0044] The power transmitting coil 51 and the power receiving coil 52 are aligned along the first direction D1. The coil spacing between the power transmitting coil 51 and the power receiving coil 52 is, for example, equal to the thickness of the ceiling material 10. In this embodiment, the "coil spacing" refers to the distance between a pair of coils. The "coil spacing" includes, for example, the distance between the coils. The "coil distance" may be the surface-to-surface distance from the surface of one coil to the surface of the other coil. By setting the coil spacing to the same length as the thickness of the ceiling material 10, it is possible to position the power transmitting and receiving unit 50 taking into account the thickness of the ceiling material 10.

[0045] For example, the mounting structure 1 has a rectifier 53. The rectifier 53 is disposed, for example, between the power receiving coil 52 and the LED lighting device 20. The rectifier 53 is fixed to the surface 12a of the decorative calcium silicate board 12. The rectifier 53 is electrically connected to the power receiving coil 52. The rectifier 53 is also electrically connected to the light emitting unit 21 via the support unit 22.

[0046] For example, the mounting structure 1 has a cover 54. The cover 54 covers a portion of the power transmitting and receiving unit 50. Specifically, the cover 54 covers the power receiving coil 52 in the internal space K. The cover 54 is disposed on one side of the LED lighting 20 in the second direction D2. The cover 54 is attached to a ceiling material 10 (for example, a decorative calcium silicate board 12). For example, the cover 54 covers the power receiving coil 52 and the rectifier 53. For example, the end of the cover 54 on the LED lighting 20 side is in contact with the support part 22. The cover 54 has, for example, a box shape. However, the cover 54 may have a dome shape, and the shape of the cover 54 is not particularly limited.

[0047] Next, the effects obtained from the mounting structure 1 for facility equipment according to this embodiment will be described in more detail. In the mounting structure 1, the LED light 20, which is wirelessly powered by the power transmitting / receiving unit 50, is placed in the internal space K. The LED light 20 receives power from the power receiving coil 52, allowing it to receive power from outside the internal space K. The first magnet 31 is placed outside the internal space K, and the second magnet 32 ​​is placed inside the internal space K. In this configuration, the LED light 20 is attracted to the second magnet 32, and the second magnet 32 ​​and the first magnet 31, which are placed on opposite sides of the ceiling material 10, are attracted to each other by magnetic force. This allows the LED light 20 to be attached to the ceiling material 10 using the magnetic force of the first magnet 31 and the second magnet 32. Therefore, there is no need to provide a through-hole in the ceiling material 10. This allows the LED light 20 to be installed on the ceiling material 10 without providing a through-hole in the ceiling material 10 for mounting the LED light 20, thereby preventing a decrease in the cleanliness of the internal space K. In addition, there is no need to block the through-holes provided in the ceiling material 10, and when it is desired to change the arrangement of the LED lighting 20, the position of the first magnet 31 and the second magnet 32 ​​can be changed to change the installation position of the LED lighting 20. This makes it easy to change the layout of the equipment including the LED lighting 20 in the interior space K and to change the production line in the interior space K. In this way, it is easy to change the arrangement of the equipment.

[0048] Furthermore, a groove 13 is provided in the ceiling material 10 on the side opposite to the LED light 20. The first magnet 31 is disposed inside the groove 13. In this case, by disposing the first magnet 31 inside the groove 13, the distance between the first magnet 31 and the second magnet 32 ​​can be shortened, and the first magnet 31 and the second magnet 32 ​​can be brought closer to each other. This strengthens the attractive force acting between the first magnet 31 and the second magnet 32, making it easier to attach the LED light 20 to the ceiling material 10 and allowing the LED light 20 to be attached to the ceiling material 10 with even greater strength.

[0049] Furthermore, the support member 41 is fixed to the surface 31a of the first magnet 31 facing away from the internal space K, and abuts against the surface 11a of the ceiling material 10 facing away from the internal space K. In this case, the support member 41 can distribute the attractive force applied to the first magnet 31 placed inside the groove 13 to the ceiling material 10. This allows the first magnet 31 to be stably fixed to the ceiling material 10.

[0050] Additionally, the second magnet 32 ​​is positioned on the opposite side of the ceiling material 10 from the portion 23 of the LED light 20. The LED light 20 is attached to the ceiling material 10 by sandwiching the portion 23 of the LED light 20 between the ceiling material 10 and the second magnet 32. In this case, the second magnet 32 ​​is fixed to the portion 23 of the LED light 20, and then the portion 23 of the LED light 20 can be supported on the ceiling material 10, thereby attaching the LED light 20 to the ceiling material 10. This makes it easy to attach the LED light 20 to the ceiling material 10.

[0051] (Second embodiment) FIG. 3 is a cross-sectional view showing a mounting structure 2 for facility equipment according to a second embodiment. FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. 3. The mounting structure 2 differs from the first embodiment described above in the arrangement of the power transmitting and receiving unit 50 and the arrangement of the rectifier 53. In addition, the mounting structure 2 differs from the first embodiment in that it includes an LED light 20B that is different from the LED light 20. The other configurations of the second embodiment are the same as those of the first embodiment. In the following, explanations of content that overlap with the above description will be omitted as appropriate. The mounting structure 2 does not have a cover 54.

[0052] The power transmitting and receiving unit 50 is disposed within a range in which the LED lighting 20B is located when viewed from the first direction D1. Specifically, the power transmitting coil 51 is disposed between the two first magnets 31 in the second direction D2. The power receiving coil 52 is disposed between the two second magnets 32 in the second direction D2. The rectifier 53 is disposed within a range in which the LED lighting 20B is located when viewed from the first direction D1. Specifically, the rectifier 53 is disposed between the power receiving coil 52 and the second magnet 32. The power receiving coil 52 and the rectifier 53 are fixed to the part 23 of the LED lighting 20B.

[0053] The LED lighting 20B has a cover 24. The cover 24 is located above the light-emitting unit 21. The cover 24 is attached to the ceiling material 10 (for example, the surface 12a of the decorative calcium silicate board 12). The cover 24 may be, for example, box-shaped. The length of the cover 24 in the second direction D2 is longer than the length of the cover 24 in the third direction D3 and the length of the cover 24 in the first direction D1. A cross section of the cover 24 perpendicular to the second direction D2 is trapezoidal. The upper side of the cross section of the cover 24 perpendicular to the second direction D2 is longer than the lower side of the cross section of the cover 24 perpendicular to the second direction D2. The cover 24 is trapezoidal when viewed from the third direction D3. The upper side of the cover 24 viewed from the third direction D3 is longer than the lower side of the cover 24 viewed from the third direction D3. For example, when viewed from the third direction D3, the length of the lower side of the cover 24 matches the length of the light-emitting unit 21 in the second direction D2.

[0054] The cover 24 houses, for example, a portion of the power transmitting and receiving unit 50. The cover 24 houses the second magnet 32, the power receiving coil 52, and the rectifier 53 inside. The cover 24 also covers a portion 23 of the LED lighting 20B. The LED lighting 20B does not have a support portion 22 (see FIG. 1 ). Components of the light-emitting unit 21, including terminals for supplying power to the light-emitting unit 21, are housed inside the cover 24. The light-emitting unit 21 may be supported by the cover 24. The light-emitting unit 21 is exposed from the cover 24. However, the cover 24 may cover the light-emitting unit 21. The portion 23 of the LED lighting 20B may have a hole into which the power receiving coil 52 fits when the cover 24 is attached to the ceiling material 10. In this case, it is possible to easily attach the power receiving coil 52 to the ceiling material 10.

[0055] As described above, in the mounting structure 2, a part of the power transmitting and receiving unit 50 (the power receiving coil 52) is disposed inside the cover 24 of the LED lighting 20B. When viewed along the first direction D1, the power receiving coil 52 is located inside the LED lighting 20B. As a result, a more compact mounting structure 2 can be achieved. In the mounting structure 2, the power transmitting and receiving unit 50 is disposed between the two first magnets 31 (the two second magnets 32). Therefore, the space between the two first magnets 31 (the two second magnets 32) can be effectively utilized.

[0056] (Third embodiment) Fig. 5 is a cross-sectional view showing a mounting structure 3 for facility equipment according to a third embodiment. Fig. 6 is a partial plan view showing a power transmission coil 51, a first magnet 31B, and a support member 41. Fig. 7 is a cross-sectional view taken along line VII-VII shown in Fig. 5. The mounting structure 3 has a first magnet 31B that is different from the first magnet 31, and a second magnet 32B that is different from the second magnet 32. The mounting structure 3 differs from the mounting structure 2 described above in the number and arrangement of the support members 41.

[0057] The mounting structure 3 has one first magnet 31B and one second magnet 32B. When viewed along the first direction D1, the first magnet 31B, the second magnet 32B, and the support member 41 are arranged inside the power transmitting and receiving unit 50, which has a ring shape. When viewed along the first direction D1, the power transmitting coil 51 and the power receiving coil 52 have a ring shape. When viewed along the first direction D1, the first magnet 31B is arranged inside the power transmitting coil 51, and the second magnet 32B is arranged inside the power receiving coil 52.

[0058] The first magnet 31B and the second magnet 32B are rectangular parallelepipeds. For example, the length of the first magnet 31B in the first direction D1 is shorter than the length of the first magnet 31B in the second direction D2 and the length of the first magnet 31B in the third direction D3. The second magnet 32B has a similar shape to the first magnet 31B.

[0059] The length in the second direction D2 of the first magnet 31B is shorter than the length in the second direction D2 of the inner edge of the power transmitting coil 51. The length in the third direction D3 of the first magnet 31B is shorter than the length in the third direction D3 of the inner edge of the power transmitting coil 51. The length in the second direction D2 of the second magnet 32B is shorter than the length in the second direction D2 of the inner edge of the power receiving coil 52. The length in the third direction D3 of the second magnet 32B is shorter than the length in the third direction D3 of the inner edge of the power receiving coil 52.

[0060] The support member 41 is fixed to the first magnet 31B. The support member 41 is disposed inside the power transmitting coil 51. The mounting structure 3 includes a plurality of support members 41. In one example, the mounting structure 3 includes two support members 41. The length of the support member 41 in the second direction D2 is shorter than the length of the first magnet 31B in the second direction D2. The length of the support member 41 in the third direction D3 is longer than the length of the first magnet 31B in the third direction D3. The length of the support member 41 in the third direction D3 is shorter than the length of the inner edge of the power transmitting coil 51 in the third direction D3. In one example, when viewed along the first direction D1, the second magnet 32B and the power receiving coil 52 are disposed in the center of the LED lighting 20B. When viewed along the first direction D1, the rectifier 53 is disposed at a position offset from the center of the LED lighting 20B.

[0061] The first magnet 31B, the second magnet 32B, and the support member 41 may be plastic magnets or rubber magnets. Plastic magnets and rubber magnets are made of materials that do not primarily contain metal, for example. The first magnet 31B, the second magnet 32B, and the support member 41 do not have to be permanent magnets or strong magnetic materials. In this case, heat generation due to electromagnetic induction can be more reliably suppressed. At least one of the first magnet 31B, the second magnet 32B, and the support member 41 may be made of a material containing plastic in the magnetic material. An example of a material containing plastic in the magnetic material is a non-metallic magnet made of a magnetic polymer (PANiCNQ) having a structure of tetracyanoquinodimethane (TCNQ), an electron acceptor, on an emeraldine-based polyaniline (PANi) skeleton.

[0062] As described above, in the mounting structure 3, when viewed along the first direction D1, the first magnet 31B is disposed inside the power transmitting coil 51, and the second magnet 32B is disposed inside the power receiving coil 52. In this case, the area inside the annular power transmitting coil 51 and the area inside the annular power receiving coil 52 can be effectively used as spaces for disposing the first magnet 31B and the second magnet 32B. This allows the mounting structure 3 to be simplified.

[0063] Various embodiments of the mounting structure for facility equipment according to the present disclosure have been described above. However, the mounting structure for facility equipment according to the present disclosure is not limited to the contents of the various embodiments described above, and may be further modified within the scope of the gist described in the claims. In other words, the shape, size, material, number, and arrangement of each part of the mounting structure for facility equipment according to the present disclosure can be changed as appropriate within the scope of the above gist.

[0064] For example, in the above-described embodiment, an example has been described in which the LED light 20 is attached to the ceiling material 10 by sandwiching a portion 23 of the LED light 20 between the ceiling material 10 and the second magnet 32. However, in the mounting structure 1, the LED light 20 may be attached to the ceiling material 10 without being sandwiched by the second magnet 32. For example, the LED light 20 may be attracted to and fixed to the lower part of the second magnet 32.

[0065] In the above-described embodiment, an example has been described in which the groove 13 is formed in the gypsum board 11. However, the groove 13 does not have to be formed in the gypsum board 11. In this case, the first magnet 31 may be disposed on the surface 11a of the gypsum board 11. Furthermore, the mounting structure does not have to include the support member 41. [Explanation of symbols]
