The lighting device 1 includes an elongated fixture 3 that is attached to an installation location such as a ceiling, and a light fixture 5 that is detachably attached to the fixture 3. The side of the lighting device 1 that emits light is referred to as the front side, and may be simply referred to as the "front side." The side of the lighting device 1 where the installation location is located is referred to as the back side, and may be simply referred to as the "back side." In terms of the positional relationship between the fixture 3 and the lighting fixture 5, the fixture 3 is located on the back side, and the lighting fixture 5 is located on the front side. The longitudinal direction of the elongated lighting device 1 may be simply referred to as the "longitudinal direction," and the short side direction of the lighting device 1 may be simply referred to as the "short side direction."

[0010] 2. Equipment The explanation will be given mainly with reference to FIGS. 1 and 2. The fixture 3 is fixed to the installation location by fasteners (not shown), such as a hanging bolt 39A and a nut 39B. The fixture 3 comprises a fixture-side base 30 and a fixture-side end cover 32. The fixture 3 comprises a terminal block 34 for supplying commercial power to the lighting fixture 5, a pair of mounting structures 36 for detachably (removably) mounting the lighting fixture 5, and the like, on the front side of the fixture-side base 30. For convenience, the fixture-side base 30 is labeled "fixture side" to distinguish it from a base 50 on the lighting fixture 5 side (lighting fixture side base) described below, and similarly, the base 50 on the lighting fixture 5 side is labeled "lighting fixture side." The fixture-side base 30 is made, for example, by bending a single metal plate, and has a recess 301 that accommodates the rear portion of the lighting fixture 5. The lead wires of the recess 301 are shown as black circles to make them easier to distinguish from the lead wires of the side plate portion 305 of the recess 301. The back plate portion 303 of the fixture side base 30 is provided with a plurality of through holes 303a for the hanging bolt 39A, a through hole 303b for the power supply side cable, a through hole (screw hole) for fixing the terminal block 34, a through hole (including an engagement groove) for fixing the mounting structure portion 36, etc.

[0011] 3.Lamps The following description will be made mainly with reference to FIGS. The lamp 5 comprises a light source unit (not shown) that uses an LED element, which is an example of a light-emitting element, as its light source, a power supply unit 52 that supplies lighting power to the light source unit, a communication unit (wireless unit) 53 that receives lighting-related operations from a controller not shown, a lamp side base 50 that mounts the light source unit on its front surface and the power supply unit 52 on its back surface, a cover 54 that covers the light source unit from the front side, end covers 56 that close both longitudinal ends of the lamp side base 50 and the cover 54, and an attachment structure 58 provided on the back surface of the lamp side base 50.

[0012] 4. Mounting structure Here, an engagement structure is used to attach the mounting structure 58 and the mounted structure 36 together. The following description will be mainly made with reference to FIG. (1) Mounting structure The mounting structure 36 includes a fixed plate 37 fixed to the back plate 303 of the appliance-side base 30, and an engaging spring body 38 provided on the fixed plate 37 and extending outward in the longitudinal direction. The fixing plate 37 has an engaging portion 371 that engages with the through-hole (engagement groove) of the back plate portion 303, a screw hole portion 373 into which a screw 349 (see FIG. 1) that is inserted from the back side through the through-hole of the back plate portion 303 of the instrument side base 30 is screwed when the engaging portion 371 is engaged with the instrument side base 30, a through-hole 375 into which one end (bent portion 385a) of the engaging spring body 38 fits, and a holding portion 377 that holds the engaging spring body 38. The engaging portion 371, the holding portion 377, the through-hole 375, etc. are formed by pressing a single metal plate. The engagement spring 38 is elastically deformable in the direction away from and toward the back plate 303 (front-to-back direction) and engages with the mounting structure 58 of the lamp fixture 5. The engagement spring 38 is formed of a single wire and has a U-shaped portion 381 formed by connecting a pair of extension portions 381a at one end with a connecting portion 381b, a coil-shaped spring portion 383 formed continuously with the end of the U-shaped portion 381 opposite the connecting portion 381b, and an extension portion 385 extending continuously from the end of the spring portion 383 opposite the U-shaped portion 381. The U-shaped portion 381 engages with the engagement receiving portion 581 of the mounting structure 58. A bent portion 385a at the end of the extension portion 385 fits into a through-hole 375 of the fixing plate 37. The retaining portion 377 of the fixed plate 37 fits into the central hole of the spring portion 383 , whereby the engaging spring body 38 is retained by the fixed plate 37 .

[0013] (2) Mounting structure As shown in Figures 2 and 3, the mounting structure 58 has an engagement receiving portion 581 for engaging with the engagement spring body 38 of the mounting structure 36, and an attachment portion 583 for attaching the mounting structure 58 to the lamp side base 50. The engagement receiving portion 581 has a U-shape or a similar shape with an opening on the lower side in a cross section perpendicular to the longitudinal direction. The mounting portion 583 is bent outward in the lateral direction from the open end of the engagement receiving portion 581. The mounting portion 583 is attached to the lamp fixture-side base 50 by inserting (sliding) its bent tip end from the longitudinal direction into a groove 501 formed in the lateral end of the fixture-side base 30. The groove 501 is formed by folding back the lateral end to the rear side.

[0014] 5. First Example The lighting device includes a lighting fixture 5 having an attachment structure 58, a mounting fixture (1007, 2007) to which an attachment structure 36 is attached, and a fixture (1003, 2003) to which the mounting fixture (1007, 2007) is attached. The mounting fixture comprises a mounting structure 3036 and a mounting fixture main body. The mounting fixture has an attachment portion for mounting the mounting structure 36 and an opposing portion on the mounting fixture body that faces the side surface (side plate portion 305) of the recess (301) of the appliance. As a result, when mounting the mounting structure 36 to the appliance (appliance body), the opposing portion faces the side surface (305), making it easy to position the mounting fixture, and as a result, it is easy to position the mounting structure 36. The attachment has a first abutment portion that abuts against a part or member provided on the device body in the longitudinal direction, and a second abutment portion that abuts against a part or member provided on the device body in the lateral direction. This positions the attachment in the longitudinal and lateral directions. Note that the object that the first abutment portion abuts against and the object that the second abutment portion abuts against may be the same part or member, or may be different parts or members. The attachment has a supported portion for being supported by a portion or member provided on the tool body, whereby the attachment is supported by the tool body. A first example of the wearing tool according to the first embodiment will be described below.

[0015] (1) First Example 1 The description will be mainly made with reference to FIGS. In the first embodiment 1, as shown in Fig. 4(b), a mounting fixture 1007 having a mounting structure 36 is mounted on an appliance main body 1030 having a positioning member 1033 provided on the back plate 303 of the recess 301 shown in Fig. 4(a). The mounting fixture 1007 here mounts one mounting structure 36. In the first embodiment 1, the part provided on the device body 1030 is the back plate portion 303, and the member provided on the device body 1030 is the positioning member 1033. The positioning member 1033 has a U-shaped portion 1330 whose cross section perpendicular to the longitudinal direction connects the outer ends in the short direction of parallel first and second side portions 1331 and 1333 with a connecting side portion 1335, and a bent portion 1336 that bends from the end of the second side portion 1333 to the rear side of the U-shaped portion 1330. The "first" and "second" of the first and second side portions are added for convenience in order to distinguish them from the other side portions. The positioning member 1033 has a first side portion 1331 fixed to the instrument body 1030 by a screw 1339 or the like. The second side portion 1333 has a recessed region 133a recessed inward in the longitudinal direction from the end in the longitudinal direction.

[0016] The mounting fixture 1007 includes a mounting structure 36 and a mounting fixture main body 1070 to which the mounting structure 36 is attached. 4 and 5, the mounting fixture 1007 and the mounting fixture main body 1070 are long in the longitudinal direction of the fixture main body 1030. Therefore, when simply referring to the longitudinal direction and the short side direction, the longitudinal direction and the short side direction of both the mounting fixture 1007 (mounting fixture main body 1070) and the fixture main body 1030 are included. As shown in FIG. 5, the attachment body 1070 has a first opposing plate portion 1071 that faces (here, abuts) the back plate portion 303 of the recess 301 of the device body 1030 from the front side, a first bent portion 1072 that bends from both ends of the first opposing plate portion 1071 in the short direction toward the front side, a second opposing plate portion 1073 that extends outward in the short direction from the front side of the first bent portion 1072 and faces the back plate portion 303, and a second bent portion 1074 that bends from the end of the short direction of the second opposing plate portion 1073 toward the front side. The wearing tool main body 1070 is formed, for example, by pressing a single metal plate or a thermoplastic resin plate, or by injection molding a resin material. The wearing device main body 1070 has a third bent portion 1075 that bends toward the front side by utilizing the through-hole 1073a of the second opposing plate portion 1073. One end of the third bent portion 1075 in the longitudinal direction (here, the end closer to the center of the longitudinal direction of the first opposing plate portion 1071) has a convex portion 1075a that protrudes toward the front side. The terms "first," "second," and "third" of the first bent portion, second bent portion, and third bent portion are used for convenience to distinguish them from other bent portions.

[0017] The attachment body 1070 has an attachment portion for attaching the attachment structure 36 on the second opposing plate portion 1073. Specifically, as shown in Fig. 3, the attachment portion is composed of a through hole 1073b for engaging with the engagement portion 371 (see Fig. 3(b)) of the attachment structure 36, and a through hole 1073c through which the screw 349 is inserted.

[0018] The facing portion of the wearing fixture 1007 is configured by the second bent portion 1074. That is, the second bent portion 1074 faces the inner surface (side surface) of the side plate portion 305 of the recessed portion 301 in the short direction. When wearing the wearing fixture 1007, positioning is facilitated by facing the second bent portion 1074 to the side surface.

[0019] The first contact portion of the mounting fixture 1007 is formed by the convex portion 1075a of the third bent portion 1075. Here, the third bent portion 1075 is configured to have a height that allows it to be inserted between the first side portion 1331 and the second side portion 1333 of the positioning member 1033. As a result, when mounting the mounting fixture 1007 to the instrument body 1030, the mounting fixture 1007 is slid in the longitudinal direction relative to the instrument body 1030, and the convex portion 1075a of the third bent portion 1075 abuts against one longitudinal end of the second side portion 133 (the end located opposite to the sliding direction) from the longitudinal direction. As a result, when mounting the mounting fixture 1007, it is positioned in the longitudinal direction. Specifically, the other end side in the longitudinal direction (sliding direction) is positioned. When the third bent portion 1075 slides, with the first opposing plate portion 1071 abutting against the back plate portion 303 of the device body 1030, the second opposing plate portion 1073 is located on the front side of the first side portion 1331 of the positioning member 1033, and the height of the third bent portion 1075 is smaller than the distance between the first side portion 1331 and the second side portion 1333, so that the third bent portion 1075 does not interfere with the positioning member 1033. Note that the convex portion 1075a protrudes toward the front side of the second side portion 1333.

[0020] The second contact portion of the wearing fixture 1007 may be configured by a first bent portion 1072. Here, the first bent portion 1072 is located inside the first side portion 1331 of the positioning member 1033 in the short direction, and its height is greater than the thickness of the first side portion 1331. As a result, when the first opposing plate portion 1071 of the mounting device 1007 is abutted against the back plate portion 303 of the device body 1030 and the second bent portion (opposing portion) 1074 is opposed to both side surfaces of the recess 301 as shown in Figure 6(b), and the mounting device 1007 is slid so that the first bent portion 1072 is positioned inside in the short direction relative to the positioning member 1033, as shown in Figure 6(a), the first bent portion 1072 is positioned inside in the short direction relative to the first side portion 1331 of the positioning member 1033, and the first bent portion 1072 can be abutted against (the end face of) the first side portion 1331 in the short direction, thereby positioning it in the short direction (outside).

[0021] The second contact portion of the wearing device 1007 may be configured by a second bent portion 1074. Here, when the wearing device 1007 is in the worn state, the second bent portion 1074 is located inside the connecting side portion 1335 of the positioning member 1033 in the short-side direction and faces the connecting side portion 1335. This positions the wearing device 1007 in the short-side direction (outward). The second bent portion 1074 is configured to have a height that allows it to be inserted between the first side portion 1331 and the second side portion 1333 of the positioning member 1033, and faces closely to the connecting side portion 1335 of the positioning member 1033. As a result, as shown in FIG. 6 , when the mounting device 1007 is mounted to the apparatus main body 1030, the second bent portion 1074 is slid in the longitudinal direction so as to face the connecting side portion 1335 of the positioning member 1033, so that the second bent portion 1074 is inserted between the first side portion 1331 and the second side portion 1333 of the positioning member 1033, and the second bent portion 1074 engages with the U-shaped portion 1330. From this perspective, the second bent portion 1074 may form a supported portion of the mounting device 1007. Furthermore, when the second bend portion 1074 slides, the first bend portion 1072 is positioned inside the first side portion 1331 of the positioning member 1033 in the short direction, the height of the first bend portion 1072 is greater than the thickness of the first side portion 1331, and the height of the third bend portion 1075 is smaller than the distance between the first side portion 1331 and the second side portion 1333, so the second bend portion 1074 does not interfere with the positioning member 1033. The second contact portion of the mounting fixture may be a side end surface of the end portion in the short side direction of the second opposing plate portion 1073. In this case, the side end surface of the end portion in the short side direction of the second opposing plate portion 1073 faces or contacts the side plate portion 305, thereby enabling the mounting fixture to be positioned in the short side direction.

[0022] The second contact portion of the wearing device 1007 may be constituted by a third bent portion 1075. Here, when the wearing device 1007 is in the worn state, the third bent portion 1075 is located outside (on the connecting side portion 1335 side) in the short-side direction relative to the bent portion 1336 of the positioning member 1033, and faces the bent portion 1336. This positions the wearing device 1007 in the short-side direction (inward). By sliding the mounting fixture 1007, the third bent portion 1075 is inserted between the first side portion 1331 and the second side portion 1333 of the positioning member 1033 and engages with the positioning member 1033. From this perspective, the third bent portion 1075 may constitute a supported portion of the mounting fixture 1007.

[0023] As shown in Fig. 5, the mounting device main body 1070 has one or more through holes 1076 and screw holes 1077. Here, they are formed in the first opposing plate portion 1071. The mounting device 1007 is slid relative to the instrument main body 1030 from the state shown in Fig. 6(b) and is fixed with screws 1078 inserted through the through holes 1076 and screws 1079 threaded into the screw holes 1077, etc., with the longitudinal direction positioned by the convex portion 1075a (first abutment portion) of the third bent portion 1075, the outward side in the lateral direction positioned by the first bent portion 1072 and the second bent portion 1074, and the inward side in the lateral direction positioned by the third bent portion 1075, as shown in Fig. 6(a). Therefore, the through holes 1076 and the screw holes 1077 may form the supported portions of the attachment 1007. In this case, the screw holes and through holes provided in the instrument body 1030 correspond to the portions provided in the instrument body.

[0024] The mounting device main body 1070 is provided with a first bent portion 1072, a second opposing plate portion 1073, a second bent portion 1074, and a third bent portion 1075 so as to be symmetrical with respect to an imaginary line that passes through the center in the short side direction and extends in the long side direction. As a result, if the positioning member 1033 is provided on the opposite side in the short side direction instead of the position shown in Fig. 4, even if one appliance has two mounted structures 36, one mounting device 1007 can be used to accommodate them, and the costs of the molds for press processing and injection molding can be reduced, allowing for inexpensive implementation.

[0025] (2) First Example 2 The description will be mainly made with reference to FIGS. 8, in the first embodiment 2, a mounting fixture 2007 having a mounting structure 36 is mounted on an instrument body 2030 having a positioning member 2033 provided in a recess 301. The mounting fixture 2007 here mounts two mounting structures 36 spaced apart in the longitudinal direction.

[0026] In the first embodiment 2, the part provided on the fixture body 2030 is the back plate part 303, and the members provided on the fixture body 2030 are the hanging bolt 39A, the nut 39B, the positioning member 2033, and the end cover 2032. As shown in Figure 9(a), the positioning member 2033 has an L-shaped portion 2333 whose cross-sectional shape perpendicular to the longitudinal direction is an inverted "L" shape having a back plate portion 2331 facing the back plate portion 303 and a side plate portion 2332 facing the side plate portion 305, a first extension portion 2334 extending inward in the short direction from both ends of the longitudinal direction on the back plate portion 303 side (rear side in the front-back direction) of the side plate portion 2332 of the L-shaped portion 2333, a second extension portion 2335 extending outward in the longitudinal direction from the extending tip of the first extension portion 2334, and a third extension portion 2336 extending further outward in the longitudinal direction from both ends of the longitudinal direction on the opposite side of the side plate portion 2332 of the L-shaped portion 2333 from the back plate portion 303 (front side in the front-back direction). The terms "first," "second," and "third" in the first stretched portion, second stretched portion, and third stretched portion are used for convenience to distinguish them from other stretched portions. As shown in Figure 7(b), the positioning member 2033 is fixed to the back plate portion 303 of the device body 2030 with screws 2339 or the like so that the side plate portion 2332 and the third extension portion 2336 abut against or are close to the side plate portion 305 of the device body 2030, and the convex portions of the back plate portion 303 fit into the two through holes in the back plate portion 3331.

[0027] As shown in FIG. 8, the mounting fixture 2007 includes a mounting structure 36 and a mounting fixture main body 2070 to which the mounting structure 36 is attached. The mounting fixture 2007 and the mounting fixture main body 2070 are long in the longitudinal direction of the fixture main body 2030. Therefore, when simply referring to the longitudinal direction and the short side direction, the longitudinal direction and the short side direction of both the mounting fixture 2007, the mounting fixture main body 2070, and the fixture main body 2030 are included. The attachment body 2070 has an opposing plate portion 2071 that faces the back plate portion 303 of the recess 301 of the device body 2030 from the front side, long bending portions 2072 that bend from both ends of the short side of the opposing plate portion 2071 to the back side along the longitudinal direction, and short bending portions 2073 that bend from both ends of the long side of the opposing plate portion 2071 to the back side along the short direction. The lengths of the long bend portion 2072 and the short bend portion 2073 in the front-to-back direction are set so that the mounting structure portion 58 of the lighting fixture can be attached to the mounting structure portion 36 of the mounting device 2007 attached to the fixture 2003. The mounting fixture 2007 is provided with through holes 2071a for fixing members 2075, which are fixed using hanging bolts 39A and nuts 39B to attach the device 2003 to the installation site, at positions spaced apart in the longitudinal direction, and screw holes 2071b for fixing the fixing members 2075 (see Figure 9(b)). As shown in FIG. 9(c), the fixing member 2075 has a box portion 2751 that is box-shaped and has an open front side, and an extension portion 2752 that extends in the short direction from the open end of the box portion 2751. The bottom portion 2753 of the box portion 2751 has a through hole 2753a that is larger than the diameters of the nut 39B and washer 39C for the hanging bolt 39A, and a through groove 2753b that extends longitudinally from the through hole 2753a. The dimension of the through groove 2753b in the short direction is larger than the diameter of the hanging bolt 39A and smaller than the diameter of the nut 39B. As a result, the fixing member 2075 (mounting device 2007) is fixed by the hanging bolt 39A and the nut 39B at the through groove 2753b, and the obverse position of the mounting device 2007 and the lamp fixture mounted on the mounting device 2007 relative to the fixture body 2030 can be adjusted by adjusting the nut 39B relative to the hanging bolt 39A. By preparing a plurality of types of fixing member 2075 with different sizes of through holes 2753a and through grooves 2753b, it is possible to accommodate various hanging bolts 39A, nuts 39B and washers 39C without changing the opposing plate portion 2071. The extension portion 2752 is provided with a screw hole for a screw 2759 for fixing the fixing member 2075 to the opposing plate portion 2071 .

[0028] The attachment body 2070 has an attachment portion for attaching the attachment target structure 36 on the opposing plate portion 2071. Specifically, as shown in Fig. 9(b), the attachment portion is composed of a through hole 2071c for engaging with the engagement portion 371 (see Fig. 3(b)) of the attachment target structure 36, and a through hole through which a screw 349 is inserted to thread into the screw hole portion 373 (see Fig. 3(b)) of the attachment target structure 36.

[0029] The facing portion of the wearing fixture 2007 is configured by the long bent portion 2072. That is, the long bent portion 2072 faces the inner surface (side surface) of the side plate portion 305 of the recessed portion 301 in the short direction. When wearing the wearing fixture 2007, positioning is facilitated by facing the long bending portion 2072 to the side surface.

[0030] The first contact portion of the wearing fixture 2007 may be configured by a short bent portion 2073. That is, the short bent portion 2073 faces the inner surface of the end cover 2032 along the short direction of the recess 301 in the longitudinal direction as shown in FIG. When the wearing fixture 2007 is attached, the bent portion 2074 abuts against the end cover 2032 in the longitudinal direction. The abutting end cover 2032 is on the opposite side of the through hole 2753a of the fixing member 2075 to the side where the through groove 2753b is located.

[0031] The first abutment portion of the mounting fixture 2007 may be configured by the longitudinal end of the through groove 2753b of the fixing member 2075. By loosening the nut 39B threaded onto the hanging bolt 39A and inserting the nut 39B and washer 39C through the through hole 2753a to the front side, and then sliding the mounting fixture 2007 in the longitudinal direction, the hanging bolt 39A abuts against the end of the through groove 2753b. This allows the mounting fixture 2007 to be positioned in the longitudinal direction. Note that the sliding direction is opposite to the side of the through hole 2753a where the through groove 2753b is located. During sliding, before the hanging bolt 39A abuts against the end of the through groove 2753b, the nut 39B and the washer 39C may abut against the box portion 2751 of the fixing member 2075. In this case, the first abutment portion is formed by a side portion along the short side direction of the box portion 2751 of the fixing member 2075 (the surface in contact with the through groove 2753b). Furthermore, when the mounting fixture 2007 is mounted, the suspension bolt 39A is inserted through the through groove 2753b of the fixing member 2075 of the mounting fixture 2007 and is screwed into the nut 39B on the front side of the bottom portion 2753 of the fixing member 2075. This allows the mounting fixture 2007 to be supported by the appliance main body 2030. From this perspective, the through groove 2753b of the fixing member 2075 (and its surrounding area) may form the supported portion of the mounting fixture 2007.

[0032] The second contact portion of the wearing device 2007 may be configured by the long bent portion 2072. Here, when the wearing device 2007 is in the worn state, the long bent portion 2072 is located inside the second extending portion 2335 of the positioning member 2033 in the short-side direction and faces the second extending portion 2335. This positions the wearing device 2007 in the short-side direction (outward).

[0033] The second contact portion of the mounting fixture 2007 may be formed by the short-side end of the through groove 2753b of the fixing member 2075. The nut 39B threaded onto the suspension bolt 39A is loosened, and the nut 39B and washer 39C are inserted through the through hole 2753a to the front side. In this state, the mounting fixture 2007 is slid in the longitudinal direction, whereby the suspension bolt 39A is positioned within the through groove 2753b. This allows it to be positioned in the short-side direction.

[0034] As shown in FIG. 8, the mounting fixture 2007 (mounting fixture main body 2070) can also be provided with a terminal block 2076 for feed wiring and a terminal block 2077 for dimming.

[0035] Second Embodiment 1. Overall As shown in FIG. 10, the lighting device 3001 includes a long fixture 3003 that is attached to an installation location such as a ceiling, and a lighting fixture 3005 that is detachably attached to the fixture 3003. The fixture 3003 and the lighting fixture 3005 have substantially the same structure as the fixture 3 and the lighting fixture 5 of the first embodiment, but differ in the mounting structure for detachably mounting the lighting fixture 3005. The mounting structure will be described below. The same reference numerals as in the first embodiment are used for the parts corresponding to those in the first embodiment, and the description thereof will be omitted. Also, an engagement structure is used for attachment.

[0036] 2. Mounting structure The following description will be mainly made with reference to FIG. The lamp 3005 includes a pair of mounting structures 3058 spaced apart in the longitudinal direction. The mounting structure 3058 includes an engagement receiving portion for engaging with the engagement spring of the mounted structure 3036, and an attachment portion for attaching the mounting structure 3058 to the lamp-side base 50. The mounting structure 3058 has a pair of standing plate portions 3581 that are spaced apart in the short direction and stand upright from the lighting fixture side base 50, a connecting plate portion 3582 that connects one end of the pair of standing plate portions 3581 in the long direction, and a bent plate portion 3583 that bends outward in the short direction from the front end of the pair of standing plate portions 3581 and faces the back surface of the lighting fixture side base 50. The connecting plate portion 3582 has a through hole 3585 through which the engaging spring body 3036 can be inserted. The engagement receiving portion is constituted by the through hole 3585 and its surrounding area formed in the connecting plate portion 3582. In other words, the engagement receiving portion is constituted by the connecting plate portion 3582 having the through hole (engagement hole) 3585. The outer end of the bent plate portion 3583 in the short direction (the end opposite to the standing plate portion 3581) is configured to be slidable from the end of the long direction of the lamp side base 50 with respect to the groove portion 501 of the lamp side base 50. In this way, the end of the bent plate portion 3583 forms an attachment portion.

[0037] 3. Mounting structure The explanation will be mainly made with reference to FIG. The mounting structure 3036 is composed of an engaging spring body made by bending a thin plate member in the front and back directions. The engaging spring body is also designated by the reference numeral "3036." The engagement spring 3036 is elastically deformable in the direction away from the back plate 303 (front-to-back direction), and by inserting it through a through hole 3585 of the mounting structure 3058 of the lighting fixture 3005, it engages with the periphery of the through hole 3585. The engagement spring 3036 has a curved portion 3361, an extending portion 3362 extending from one end of the curved portion 3361 in the longitudinal direction along the back plate 303, and a folded portion 3363 folded back at the other end of the curved portion 3361 in the longitudinal direction. A through hole is formed in the extension portion 3362, and a screw 3039 passing through the through hole is screwed into a screw hole in the back plate portion 303. In this way, the engaging spring body 3036 is fixed to the back plate portion 303. The folded portion 3363 is intended to prevent the engaging spring body 3036 inserted through the through hole 3585 of the mounting structure portion 3058 from coming out of the through hole 3585 .

[0038] 4. Second Example The lighting device comprises a lighting fixture 3005 having an attachment structure 3058, a mounting fixture to which an attachment structure 3036 is attached, and a fixture to which the mounting fixture is attached. The mounting fixture comprises a mounting structure 3036 and a mounting fixture main body. The mounting fixture has, on its main body, a mounting portion for mounting the mounting structure 3036 and an opposing portion that faces the side surface (side plate portion 305) of the recess 301 of the appliance (3003). As a result, when attaching the mounting structure part 3036 to the appliance (apparatus body), the opposing part faces the side surface (305), making it easy to position the attachment device, and as a result, it is easy to position the mounting structure part 3036. The attachment has a first abutment portion that abuts against a portion or member provided on the device body in the longitudinal direction, and a second abutment portion that abuts against a portion or member provided on the device body in the lateral direction. This positions the attachment in the longitudinal and lateral directions. The attachment has a supported portion that is supported by a portion or member provided on the device body. This supports the attachment to the device body. A second example of the wearing tool according to the second embodiment will be described below.

[0039] (1) Second Example 1 In Second Example 1, the mounting device main body 1070 of First Example 1 of the first embodiment is used as the mounting device main body, and a mounting device 3007 having a mounting structure 3036 shown in Fig. 10(a) is mounted to an apparatus main body 1030 having a positioning member 1033 of First Example 1 shown in Fig. 4. Note that in Second Example 1 as well, one mounting device 3007 mounts one mounting structure 3036. The following description will be mainly made with reference to FIG. In Second Example 1, the part provided on the device body 1030 is the back plate portion 303, and the member provided on the device body 1030 is the positioning member 1033, similar to Example 1 of the first embodiment. Therefore, a description of the positioning member 1033 will be omitted. As described above, the mounting fixture 3007 includes the mounting structure 3036 and the mounting fixture main body 1070 of the first embodiment 1. Therefore, the description of the mounting fixture main body 1070, which is the same as that of the first embodiment 1, will be omitted and only the differences will be described, but the same effects as those of the first embodiment 1 can be obtained. The mounting fixture 3007 has an attachment portion for attaching the mounting structure portion 3036 on the first opposing plate portion 1071 of the mounting fixture main body 1070. A screw 3039 is used for attachment, and the attachment portion is composed of a screw hole (not shown) into which the screw 3039 screws. The fixture main body (1030) may have a through hole for the screw 3039 at a position corresponding to the screw 3039. Also, instead of the screw hole of the mounting fixture main body 1070, a through hole may be used, and the fixture main body (1030) may have a screw hole.

[0040] (2) Second Example 2 In the second embodiment 1, the mounting structure 3036 is mounted to the mounting fixture main body 1070 by a screw 3039 . 11(b), the mounting fixture 3007A of the second embodiment 2 integrally comprises an attachment target structural part 3036A corresponding to the attachment target structural part 3036 and an attachment target main body part 1070A corresponding to the mounting fixture main body 1070. Here, they are integrated so that one end 3362A in the longitudinal direction of the attachment target structural part 3036A is connected to the other end 1071Aa in the longitudinal direction of the mounting fixture main body part 1070A.

[0041] (3) Second Example 3 In the second example 3, the mounting device main body 2070 (see FIG. 8) of the first example 2 of the first embodiment is used as the mounting device main body, and a mounting device 4007 having the mounting structure portion 3036 shown in FIG. 10(a) is attached to the equipment main body 2030 fixed with the hanging bolt 39A and nut 39B of the first example 2 shown in FIG. 8. In the second embodiment 3 as well, one mounting fixture 4007 mounts two mounting structures 3036 . This will be explained using FIG. 11(c). In the second embodiment 3, the part provided on the fixture body 2030 is the back plate part 303, and the members provided on the fixture body 2030 are the hanging bolt 39A, the nut 39B, the positioning member 2033, and the end cover 2032. The hanging bolt 39A, nut 39B, positioning member 2033, and end cover 2032 are the same as those in the first embodiment, Example 1 2. Therefore, a description of the hanging bolt 39A, nut 39B, positioning member 2033, etc. will be omitted. As described above, the mounting fixture 4007 comprises the mounting structure 3036 and the mounting fixture main body 2070A, which corresponds to the mounting fixture main body 2070 of the first embodiment 2. For this reason, the description of the mounting fixture main body 2070, which is the same as that of the first embodiment 2, will be omitted and only the differences will be described, but the same effects as those of the first embodiment 2 can also be obtained. The mounting fixture 4007 has an attachment portion on the opposing plate portion 2071 of the mounting fixture main body 2070A for attaching the mounting structure portion 3036. The attachment is performed using a screw 3039, and the attachment portion is configured with a screw hole (not shown) into which the screw 3039 screws.

Overall As shown in FIG. 12, the lighting device 5001 includes a long fixture 5003 that is attached to an installation location such as a ceiling, and a lighting fixture 5005 that is detachably attached to the fixture 5003. The fixture 5003 and the lighting fixture 5005 have substantially the same structure as the fixture 3 and the lighting fixture 5005 of the first embodiment, but differ in the mounting structure for detachably mounting the lighting fixture 5005. The mounting structure will be described below. The same reference numerals as in the first embodiment are used for the parts corresponding to those in the first embodiment, and the description thereof will be omitted. Also, an engagement structure is used for attachment.

[0043] 2. Mounting structure This will be explained mainly with reference to FIG. The lamp 5005 includes a pair of mounting structures 5058 spaced apart in the longitudinal direction. The mounting structure 5058 includes an engagement spring body 5581 for engaging with the engagement receiving portion 5037 of the mounted structure 5036 , and a fixing plate 5582 for fixing the engagement spring body 5581 to the lamp side base 50 .

[0044] The engagement spring 5581 is elastically deformable in the direction away from the lamp base 50 (front-to-back direction) and is composed of a single wire. The engagement spring 5581 has a U-shaped portion 5581a formed by connecting one end of a pair of extension portions, a coil-shaped spring portion 5581b formed continuously with the end of the U-shaped portion 5581a opposite the connecting side, and an extension portion 5581c extending continuously from the end of the spring portion 5581b opposite to the U-shaped portion 5581a. The U-shaped portion 5581a engages with an engagement receiving portion 5037 of the mounting structure 5036.

[0045] The fixing plate 5582 is formed by pressing, for example, a single metal plate. The fixing plate 5582 includes a first opposing plate portion 5582a extending in the longitudinal direction facing the lamp side base 50, a holding portion 5582b extending in the lateral direction from a middle portion of the first opposing plate portion 5582a in the longitudinal direction and passing through a central hole of the spring portion 5581b of the engagement spring body 5581 to hold the spring portion 5581b, and a first bending portion 5582b at the lateral end of the first opposing plate portion 5582a and bending from both longitudinal end portions relative to the holding portion 5582b toward the front side. 82c, a second opposing plate portion 5582d extending outward in the short direction from the front end of the first bent portion 5582c and facing the lighting fixture side base 50, a second bent portion 5582e bending from the short end portion of the second opposing plate portion 5582d toward the front side, and a third opposing plate portion 5582f extending outward in the short direction from the front end of the second bent portion 5582e and fitting slidably from the longitudinal direction into groove portions 501 at both ends of the short direction of the lighting fixture side base 50. In addition, in a state in which the engagement spring body 5581 is supported by the fixed plate 5582, the engagement spring body 5581 is located on the rear side of the second opposing plate portion 5582d.

[0046] 3. Mounting structure The explanation will be mainly made with reference to FIG. The mounting structure 5036 has an engagement receiving portion 5037 having an engagement hole 5037a with which the engagement spring body 5581 of the mounting structure 5058 engages, and an extension plate portion 5038 extending from the back end of the engagement receiving portion 5037 along the back plate portion 303 of the appliance body 5030. The mounting structure 5036 is supported by the support claw 5303a of the fixture body 5030, and is attached to the fixture body 5030 by threading a screw 5039 passing through the extension plate portion 5038 (through hole 5038c: see Figure 13(b)) into the screw hole of the back plate portion 303. The support claw 5303a is formed inside the U-shaped through groove, bent from the back plate 303 to the front side, and then extends in the longitudinal direction parallel to the back plate 303. The support claw 5303a supports the supported portion 5038b (see FIG. 13(b)) located on the side to which the support claw 5303a extends relative to the notched portion 5038a (see FIG. 13(b)) of the extension plate portion 5038 of the mounting structure 5036. A plurality of notched portions 5038a and support claws 5303a (for example, two) are provided at intervals in the lateral direction. This allows the mounting structure 5036 to be held in a stable state.

[0047] 4. Third Example The lighting device comprises a lighting fixture 5005 having an attachment structure 5058, a mounting fixture to which an attachment structure 5036 is attached, and a fixture to which the mounting fixture is attached. The mounting fixture comprises a mounting structure 5036 and a mounting fixture main body. The mounting fixture has, on its main body, a mounting portion for mounting the mounting structure 5036, and an opposing portion that faces the side surface (side plate portion 305) of the recess 301 of the appliance. As a result, when attaching the mounting structure part 5036 to the appliance (apparatus body), the opposing part faces the side surface (305), making it easy to position the attachment device, and as a result, it is easy to position the mounting structure part 3036. The attachment has a first abutment portion that abuts against a portion or member provided on the device body in the longitudinal direction, and a second abutment portion that abuts against a portion or member provided on the device body in the lateral direction. This positions the attachment in the longitudinal and lateral directions. The attachment has a supported portion that is supported by a portion or member provided on the device body. This supports the attachment to the device body. Hereinafter, a third example of the wearing tool according to the third embodiment will be described.

[0048] (1) Third Example 1 In Third Example 1, the mounting device main body is the mounting device main body 1070 (corresponding to mounting device main body 1070B) of First Example 1 of the first embodiment, and a mounting device 5007 having a mounting structural part 5036A corresponding to the mounting structural part 5036 shown in Fig. 12 is mounted to an apparatus main body 1030 having a positioning member 1033 of First Example 1 shown in Fig. 4. Note that in Third Example 1 as well, one mounting device 5007 mounts one mounting structural part 5036A. This will be explained using FIG. In Third Example 1, the part provided on the device body 1030 is the back plate portion 303, and the member provided on the device body 1030 is the positioning member 1033, similar to Example 1 of the first embodiment. Therefore, a description of the positioning member 1033 will be omitted. As described above, the mounting fixture 5007 comprises an attachment structure 5036A and a mounting fixture main body 1070B that corresponds to the mounting fixture main body 1070 of the first embodiment 1. For this reason, the description of the mounting fixture main body 1070, which is the same as that of the first embodiment 1, will be omitted and only the differences will be described, but the same effects as those of the first embodiment 1 can also be obtained. The mounting device 5007 has an attachment portion for attaching the mounting structure portion 5036A to the second opposing plate portion 1073 of the mounting device main body 1070B. For attachment, support claw portions 1073d having the same configuration as the support claw portions 5303a of the device main body 5030 shown in Fig. 12 and screws 5039 are used. In other words, the attachment portion is made up of the support claw portions 1073d that bend from the second opposing plate portion 1073 toward the front side and then extend in the longitudinal direction along the second opposing plate portion 1073, and the screw holes 1073e of the second opposing plate portion 1073. The screw 5039 is inserted through the through hole 5038d (see FIG. 13(b)) of the extension plate portion 5038 of the mounting structure portion 5036A, and then threaded into the screw hole 1073e of the second opposing plate portion 1073. Furthermore, a plurality of (for example, two) notched portions 5038a and support claw portions 1073d are provided at intervals in the short side direction. This allows the mounting structure portion 5036A to be held in a stable state.

[0049] (2) Third Example 2 In the third example 2, the mounting device main body 2070 (corresponding to the mounting device main body 2070B) of the first example 2 of the first embodiment is used as the mounting device main body, and a mounting device 6007 having the mounting structure part 5036 shown in FIG. 12 is attached to the equipment main body 2030 fixed with the hanging bolt 39A and nut 39B of the first example 2 shown in FIG. 8. In the third embodiment 2 as well, one mounting fixture 6007 mounts two mounting structures 5036 . This will be explained using FIG. In the third embodiment 2, the part provided on the fixture body 2030 is the back plate part 303, and the members provided on the fixture body 2030 are the hanging bolt 39A, the nut 39B, the positioning member 2033, and the end cover 2032. The hanging bolt 39A, nut 39B, positioning member 2033, etc. are the same as those in Example 2 of the first embodiment, so a description of the hanging bolt 39A, nut 39B, positioning member 2033, etc. will be omitted. As described above, the mounting fixture 6007 includes the mounting structure 5036 and the mounting fixture main body 2070B, which corresponds to the mounting fixture main body 2070 of the first embodiment 2. Therefore, the description of the mounting fixture main body 2070, which is the same as that of the first embodiment 2, will be omitted and only the differences will be described, but the same effects as those of the first embodiment 2 can be obtained. The mounting fixture 6007 has an attachment portion on the opposing plate portion 2071 of the mounting fixture main body 2070B for attaching the mounting structure portion 5036. For attachment, a support claw portion 2071d having the same configuration as the support claw portion 5303a of the device main body 5030 shown in Fig. 12 and a screw 5039 are used. In other words, the attachment portion is made up of the support claw portion 2071d that bends from the opposing plate portion 2071 to the front side and then extends in the longitudinal direction along the opposing plate portion 2071, and a screw hole (not shown) into which the screw 5039 screws. The screw 5039 is inserted through the through hole 5038c (see FIG. 13(b)) of the extension plate portion 5038 of the mounting structure portion 5036, and then threaded into a screw hole (not shown) of the opposing plate portion 2071. Furthermore, a plurality of (for example, two) notched portions 5038a and support claw portions 2071d are provided at intervals in the short side direction. This allows the mounting structure portion 5036 to be held in a stable state.

[0050] Although the embodiments have been described above, the present invention is not limited to these embodiments, and the following modified examples are also possible. Furthermore, the embodiments may be combined with each other, or with modified examples, or with modified examples. Furthermore, examples not described in the embodiments and modifications, and design changes within the scope of the present invention are also included in the present invention.

[0051] <Modification> (1) The fixture 3, 2003 was a so-called inverted Fuji type, in which the short-side dimensions become smaller as it moves away from the installation surface to the front side, but it may also be a so-called cap-type, in which the short-side dimensions become larger as it moves away from the installation surface to the front side. (2) The device 1003 shown in FIG. 4 has the positioning member 1033 on one side in the short side direction, but the device 1003 may have the positioning member 1033 on both sides in the short side direction. (3) The attachment body 1070 shown in FIG. 4(b) has a first bent portion 1072, a second bent portion 1074, and a third bent portion 1075 on both sides of the short side, but if the device has one positioning member 1033, the attachment body 1070 may have the first bent portion 1072, the second bent portion 1074, and the third bent portion 1075 only on the side where the positioning member 1033 is located. (4) For example, when a bridge (bridge portion) 303c is provided on the back plate portion 303 of the device body 7030 as shown in FIG. 15, the attachment of the attachment device to the device body may be such that an extension portion 1071c extending longitudinally from the first opposing plate portion 1071 of the attachment device body 1070C passes through the bridge 303c and is fixed by a screw 3039. That is, the wearing device main body (1070, 1070B, 1070C) and the wearing device main body portion 1070A may have an extension portion 1071c in the first opposing plate portion 1071, through which the bridge 303c of the device main body is inserted and fixed. (5) In the mounting fixture 3007 shown in FIG. 11(a), the mounting structure portion 3036 is provided on the first opposing plate portion 1071 of the mounting fixture main body 1070, but it may also be provided on the second opposing plate portion 1073 (of the screw hole 1073f) of the mounting fixture main body 1070D, for example, as shown in FIG. 16.

[0052] (6) The invention is a lighting device comprising a lamp, a mounting device, and an appliance, but it may also be a lighting set comprising a lamp and a mounting device, for example. (7) The mounting device main bodies 1070, 1070B, 1070C, 2070, 2070A, 2070B and the mounting device main body 1070A have a second bent portion 1074 and a long bent portion 2072 as opposing portions that face the side plate portions 305 of the appliance main bodies 1030, 3030, 5030. The second bent portion 1074 bends toward the front side from the second opposing plate portion 1073, and the long bent portion 2072 bends toward the front side from the opposing plate portion 2071. However, the second bent portion and the long bent portion may be bent toward the back side, or may have a portion that bends toward the front side and a portion that bends toward the back side. In addition, the opposing portion may be formed by the short end surface of the second opposing plate portion 1073 on which the second bent portion 1074 is not formed, or may be formed by the short end surface of the opposing plate portion 2071 on which the long bent portion 2072 is not formed. The facing portion only needs to face the side plate portion of the appliance body, and may be in contact with or spaced apart from the side plate portion. Note that abutting or being close to the side plate portion allows for better positioning in the short direction and makes it easier to attach the attachment. The facing portions of the wearing tool main bodies 1070, 1070B, 1070C, 2070, 2070A, 2070B and the wearing tool main body 1070A may function as second contact portions. (8) The convex portion 1075a, which is an example of the first abutment portion of the attachment main body 1070, 1070B, 1070C and the attachment main body 1070A, protrudes from the third bend portion 1075 to the rear side, but may also protrude inward in the short direction to abut against the bend portion 1336 of the positioning member 1033 from the longitudinal direction. (9) The first and / or second contact portions of the mounting device main bodies 1070, 1070B, 1070C and the mounting device main body 1070A may be configured to abut against (or be close to) the hanging bolt 39A, the nut 39B, the washer 39C (see FIG. 4) disposed between the nut 39B and the device main body 1030, and the fixing bolt for directly fixing the device to the installation site. Specifically, the end faces of the notches 1071d formed on the longitudinal ends of the first opposing plate portions 1071 of the mounting device main bodies 1070, 1070B, 1070C and the mounting device main body 1070A can be configured to abut against (or be close to) the hanging bolt 39A, the nut 39B, the washer 39C, and the fixing bolt in the longitudinal and / or lateral directions, thereby restricting the positions in the longitudinal and / or lateral directions. Furthermore, a through hole for the hanging bolt 39A (for example, the through hole 2753a and the through groove 2753b of the fixing member 2075, but either one may be used) may be provided in the mounting device main bodies 1070, 1070B, 1070C and the mounting device main body part 1070A, so that the side surface (end face) of the through hole abuts or is close to the hanging bolt 39A. (10) When the attachment body 1070, 1070B, 1070C and the attachment body portion 1070A are positioned adjacent to an end cover of the appliance (e.g., the appliance side end cover 32), the attachment body 1070, 1070B, 1070C and the attachment body portion 1070A may have a first abutment portion that abuts (or is adjacent to) the end cover of the appliance.

[0053] (11) When the power supply unit (50) is provided on the appliance side, the attachment main body 1070, 1070B, 1070C, 2070, 2070A, 2070B and the attachment main body 1070A may have a first abutment portion and / or a second abutment portion that abuts (is close to) the power supply unit (50) in the longitudinal direction and / or the lateral direction. (12) When the mounting device main bodies 1070, 1070B, 1070C, 2070, 2070A, 2070B and the mounting device main body 1070A are mounted on an apparatus body having a positioning member 1033, they may have abutting portions that abut (or fit) in the longitudinal and / or lateral directions against the side surfaces of the opening 1331a or recess of the positioning member 1033. This allows them to be positioned in the longitudinal and / or lateral directions. (13) The opposing portions of the wearing tool main bodies 1070, 1070B, 1070C, 2070, 2070A, 2070B and the wearing tool main body 1070A may function as second contact portions. (14) The wearing device main bodies 1070, 1070B, 1070C and the wearing device main body portion 1070A may have the configuration of the wearing device main bodies 2070, 2070A, 2070B. Conversely, the wearing device main bodies 2070, 2070A, 2070B may have the configuration of the wearing device main bodies 1070, 1070B, 1070C and the wearing device main body portion 1070A. (15) In the attachment main bodies 1070, 1070B, 1070C and the attachment main body 1070A, the parts or members provided on the fixture main body with which the first abutment part abuts, the parts or members provided on the fixture main body with which the second abutment part abuts, and the parts or members provided on the fixture main body with which the supported part is supported include parts that constitute the fixture main body (for example, back plate parts or side plate parts that constitute recesses), end covers provided on the fixture main body, fixing bolts that directly or indirectly fix the fixture main body to the installation part, hanging wires or hanging bolts, nuts, washers, positioning members, power supply units, terminal blocks, communication units (wireless units), etc. In addition, the object against which the first abutment portion abuts, the object against which the second abutment portion abuts, and the object against which the supported portion is supported may all be the same, may all be different, or may be partially the same. (16) In the mounting device main bodies 2070, 2070A, and 2070B, the parts or members provided on the device main body with which the first abutment part abuts, the parts or members provided on the device main body with which the second abutment part abuts, and the parts or members provided on the device main body with which the supported part is supported include parts that constitute the device main body (for example, back plate parts or side plate parts that constitute the recesses), end covers provided on the device main body, fixing bolts that directly or indirectly fix the device main body to the installation part, hanging wires or hanging bolts, nuts, washers, positioning members, power supply units, terminal blocks, communication units (wireless units), etc. In addition, the object against which the first abutment portion abuts, the object against which the second abutment portion abuts, and the object against which the supported portion is supported may all be the same, may all be different, or may be partially the same.
