  The mounting bracket 30 is a component for mounting the housing 20 to the mounting object W. The mounting bracket 30 is attached to both ends of the casing 20 in the longitudinal direction. Note that the mounting position of the mounting bracket 30 of the mounting bracket 30 is not limited to both ends. As long as the pair of protrusions 40 are formed, the mounting bracket 30 may be taken at an arbitrary place. For example, you may attach to the center part of the longitudinal direction of the housing | casing 20. FIG. The mounting bracket 30 is formed of a metal sheet metal member. The mounting bracket 30 can be elastically deformed. The mounting bracket 30 can be engaged with the pair of protrusions 40. The mounting bracket 30 includes a connection portion 31, an engagement portion 32a, and an engagement portion 32b. The connection part 31 connects the engaging part 32a and the engaging part 32b.

  The end shade 50 is provided at both ends of the housing 20. The end shade 50 is formed of the same material as the shade 14, for example. The end shade 50 is made of, for example, a translucent acrylic resin material having translucency. Therefore, the light irradiated from the light source unit 10 is not blocked. Note that the end shade 50 may be formed of a light shielding material.

  The housing 20 can be attached to and detached from the mounting bracket 30. When the housing 20 is detached from the mounting bracket 30, the engaging portion 32a and the engaging portion 32b are pushed by the protrusion 40 and elastically deformed in the direction indicated by the arrow D1. Therefore, the housing 20 can be easily detached from the mounting bracket 30.

  With reference to FIG. 2 and FIG. 3, the attachment metal fitting 30 which concerns on embodiment of this invention is demonstrated. FIG. 3A is a perspective view of the mounting bracket 30 according to the embodiment of the present invention. FIG. 3B is a cross-sectional view of the mounting bracket 30 according to the embodiment of the present invention. FIG. 3C is a top view of the mounting bracket 30 according to the embodiment of the present invention. The mounting bracket 30 includes a connection portion 31, an engagement portion 32a, and an engagement portion 32b.

  A through hole 36 is formed in the connection portion 31. The through hole 36 is provided in the center of the connection portion 31. The attachment fitting 30 is attached to the attachment object W by inserting a screw into the through hole 36.

  The connection part 31 is flat, for example. By making the connecting portion 31 flat, it is preferable since the posture of the mounting bracket 30 and the luminaire 100 attached thereto is stabilized when the mounting bracket 30 is mounted on the surface of the mounting target W. The connection portion 31 is formed with a notch 37a and a notch 37b. The notch 37a and the notch 37b are formed on the side of the connecting part 31 where the engaging part 32a and the engaging part 32b are not connected among the sides of the connecting part 31. The notch 37a and the notch 37b are formed to face each other. For example, when two mounting brackets 30 are arranged on the mounting target W, the two mounting brackets 30 are formed by matching the notches 37a and 37b of the two mounting brackets 30 with the reference line of the mounting target W. They can be arranged in parallel.

  The connection part 31 has the fitting hole 39a and the fitting hole 39b. The fitting hole 39a and the fitting hole 39b will be described later with reference to FIG.

  The engaging part 32a has a standing part 33a, a protruding part 34a, and a folded part 35a. The standing portion 33a rises from the connecting portion 31 in a substantially orthogonal direction. The protruding portion 34a is connected to the standing portion 33a. The folded portion 35a is connected to the protruding portion 34a.

  Similarly, the engaging part 32b has a standing part 33b, a protruding part 34b, and a folded part 35b. The standing portion 33 b rises from the connection portion 31 in a substantially orthogonal direction. The protruding portion 34b is connected to the standing portion 33b. The folded portion 35b is connected to the protruding portion 34b.

  The protruding part 34a and the protruding part 34b extend from the standing part 33a and the standing part 33b toward the folded part 35a and the folded part 35b in a direction away from each other. The folded part 35a and the folded part 35b extend from the projecting part 34a and the projecting part 34b in a direction approaching each other. In a state where the housing 20 is attached to the mounting bracket 30 (hereinafter referred to as an attached state), the folded portion 35a and the folded portion 35b are in contact with the protruding portion 40 of the housing 20 (see FIG. 2B). ). Therefore, when removing the housing 20 from the attached state, the protruding portion 40 of the housing 20 is not caught by the protruding portion 34a and the protruding portion 34b. As a result, the housing 20 can be easily detached from the mounting bracket 30.

  An opening 38a is formed in the engaging portion 32a. An opening 38b is formed in the engaging portion 32b. Therefore, the elastic force of the engaging part 32a and the engaging part 32b can be reduced appropriately. As a result, attachment of the housing 20 to the mounting bracket 30 and removal of the housing 20 from the mounting bracket 30 can be performed smoothly. The elastic force of the engaging part 32a and the engaging part 32b can be adjusted by adjusting the ratio of the area of the opening 38a and the opening 38b to the engaging part 32a and the engaging part 32b. For example, if the ratio of the area of the opening 38a to the engaging part 32a is reduced, the elastic force of the engaging part 32a is increased (the engaging part 32a is hard), and if the ratio of the area of the opening 38a to the engaging part 32a is increased. The elastic force of the joint portion 32a is low (the engaging portion 32a is soft). In the present embodiment, the opening 38a and the fitting hole 39a are connected. Moreover, the opening 38b and the fitting hole 39b are connected.

  With reference to FIG.2 (b), the relationship between the magnitude | size of the attachment metal fitting 30 and the space | interval of a pair of projection part 40 is demonstrated. In FIG.2 (b), the space | interval d1 shows the space | interval of the intersection line 91a and the intersection line 91b. The intersection line 91a indicates an intersection line between the connecting portion 31 and the standing portion 33a. The intersection line 91b indicates an intersection line between the connection portion 31 and the standing portion 33b. The interval d2 indicates the interval between the pair of protrusions 40. The interval d3 indicates the interval between the intersection line 92a and the intersection line 92b. The intersection line 92a indicates an intersection line between the protruding portion 34a and the folded portion 35a. The intersection line 92b indicates an intersection line between the protruding portion 34b and the folded portion 35b. The interval d4 indicates the interval between the tip 35a1 of the folded portion 35a and the tip 35b1 of the folded portion 35b.

  As shown in FIG. 2B, the interval d1 is shorter than the interval d2. The interval d3 is longer than the interval d2. Therefore, in the attached state, the engaging portion 32 a and the engaging portion 32 b are elastically deformed and engage with the pair of protrusions 40.

  Further, the interval d4 is smaller than the interval d2. Therefore, the housing 20 can be removed from the mounting bracket 30 without the tip 35a1 of the folded portion 35a and the tip 35b1 of the folded portion 35b being caught by the pair of protrusions 40.

  With reference to FIGS. 1 to 4, attachment of the mounting bracket 30 of the housing 20 will be described. FIG. 4A is an exploded perspective view of an end portion of the housing 20. FIG. 4B is a perspective view of the end portion of the housing 20.

  As shown in FIG. 4B, the end shade 50 has a main body 51 and a protrusion 52. The protruding part 52 protrudes from the main body part 51. The protrusion 52 is semicircular. The shape of the protrusion 52 of the end shade 50 corresponds to the shape of the shade 14. By attaching the screw 53 to the screw attachment portion 26, the end shade 50 is attached to the main body portion 21 of the housing 20.

  First, the mounting bracket 30 is fixed to an arbitrary position of the mounting target W with screws 19 (see FIG. 1). The mounting bracket 30 is disposed such that the intersection line 91a between the rising portion 33a of the mounting bracket 30 and the connection portion 31 of the mounting bracket 30 faces the longitudinal direction (Y direction) of the housing 20 of the lighting fixture 100 to be disposed. . The casing 20 is attached to the mounting bracket 30 by bringing the casing 20 close to the mounting bracket 30 from the state where the casing 20 faces the mounting bracket 30. Specifically, first, the housing 20 and the mounting bracket 30 are approached from above the mounting bracket 30 from the state where the casing 20 and the mounting bracket 30 are separated (see FIG. 4A). The 30 protrusions 34a and 34b come into contact with each other. Then, by displacing the housing 20 downward, the pair of protrusions 40 pushes the protrusions 34a and 34b, and the engagement parts 32a and 32b are in the directions indicated by the arrow D1 (see FIG. 2B). Elastically deforms. When the casing 20 is further displaced downward, the pair of projections 40 get over the intersection line 92a and the intersection line 92b, and the engagement part 32a and the engagement part 32b are deformed in the direction opposite to the arrow D1 by the elastic return force. And a pair of projection part 40 contacts the folding | returning part 35a and the folding | returning part 35b, and attachment is completed (refer FIG.4 (b)). In FIG. 4A and FIG. 4B, the screw 19 is omitted. Thus, the projection part 40 of the housing | casing 20 and the engaging part 32a and the engaging part 32b of the attachment metal fitting 30 contact, and the engaging part 32a and the engaging part 32b elastically deform, and thereby the housing 20 Is attached to the mounting bracket 30. As shown in FIG. 4B, the engaging portion 32 a and the engaging portion 32 b engage with the protruding portion 40 in the attached state. Since the engaging portion 32 a and the engaging portion 32 b are elastically deformed, a force to return to the original shape acts, and the engaging portion 32 a and the engaging portion 32 b are firmly engaged with the protruding portion 40.

  Next, removal of the housing 20 from the mounting bracket 30 will be described with reference to FIGS. First, the housing 20 is displaced upward from the state in which the housing 20 and the mounting bracket 30 are attached (see FIG. 4B), so that the pair of protruding portions 40 causes the folded portion 35a and the folded portion 35b to move. By pushing, the engaging part 32a and the engaging part 32b are elastically deformed in the direction indicated by the arrow D1 (see FIG. 2B). Further, the casing 20 is displaced upward, and the pair of protrusions 40 get over the intersection line 92a and the intersection line 92b. Then, the engagement of the engagement portion 32a and the engagement portion 32b with the pair of protrusions 40 is released, whereby the removal of the mounting bracket 30 of the housing 20 is completed (see FIG. 4A). As described above, when the housing 20 is detached from the mounting bracket 30, the engaging portion 32 is elastically deformed by being pushed by the pair of protrusions 40 by displacing the housing 20 upward of the mounting bracket 30. . Therefore, the housing 20 can be easily and smoothly removed from the mounting bracket 30.

  With reference to Fig.5 (a) and FIG.5 (b), the lighting fixture 100 which concerns on embodiment of this invention is demonstrated. Fig.5 (a) is a top view of the lighting fixture 100 which concerns on embodiment of this invention. FIG.5 (b) is a bottom view of the lighting fixture 100 which concerns on embodiment of this invention.

  As shown in FIGS. 5A and 5B, in the mounted state, the mounting bracket 30 does not protrude in the longitudinal direction (Y direction) and the width direction (X direction) of the housing 20 and is inside the open portion 28. Is in the range. Therefore, the lighting fixture 100 can be attached to the attachment object W even when the mounting space of the lighting fixture 100 cannot be secured sufficiently. That is, even if there is almost no space around the lighting fixture 100 in the mounting target W, the lighting fixture 100 can be mounted on the mounting target W.

  As described above with reference to FIGS. 1 to 5, in the lighting fixture 100, the pair of engaging portions (the engaging portion 32 a and the engaging portion 32 b) of the mounting bracket 30 is the inner peripheral surface of the housing 20. Engage with a pair of protrusions 40 formed on 29. Therefore, an increase in the width of the installation area of the lighting fixture 100 can be suppressed.

  Further, when the casing 20 is detached from the mounting bracket 30, the engaging portion 32 is pushed by the pair of protrusions 40 and is elastically deformed by displacing the casing 20 upward of the mounting bracket 30. Therefore, the housing 20 can be smoothly removed from the mounting bracket 30.

  Further, the folded portions 35 a and 35 b are in contact with the protruding portion 40 of the housing 20 in the attached state. Further, the distance d4 between the tip 35a1 of the turned-up portion 35a and the tip 35b1 of the turned-up portion 35b is shorter than the distance d2 between the pair of protrusions 40. Therefore, when removing the housing 20 from the attached state, the protruding portion 40 of the housing 20 is not caught by the protruding portion 34a and the protruding portion 34b. As a result, the housing 20 can be easily detached from the mounting bracket 30.

  In addition, the distance d1 between the line of intersection 91a between the connecting portion 31 and the one standing portion 33a and the line of intersection 91b between the connecting portion 31 and the other standing portion 33b is shorter than the distance d2 between the pair of protrusions 40. Further, the distance d3 between the intersection line 92a between the one protruding portion 34a and the one folded portion 35a and the intersection line between the other protruding portion 34b and the other folded portion 35b is larger than the distance d2 between the pair of protruding portions 40. Also long. Therefore, in the attached state, the engaging portion 32 a and the engaging portion 32 b are elastically deformed and engage with the pair of protrusions 40.

  The engaging portion 32 is formed with an opening 38a and an opening 38b. Therefore, the elastic force of the engaging part 32 can be reduced appropriately. As a result, attachment of the housing 20 to the mounting bracket 30 and removal of the housing 20 from the mounting bracket 30 can be performed smoothly.

  Further, the connection portion 31 is formed with a notch 37a and a notch 37b. When the plurality of mounting brackets 30 are arranged on the mounting target W, the plurality of mounting brackets 30 are made parallel by aligning the notches 37a and the notches 37b of the plurality of mounting brackets 30 with the reference line of the mounting target W. Can be arranged.

  With reference to FIG. 6, the attachment metal fitting 30 which concerns on embodiment of this invention is demonstrated. FIG. 6 is a top view of the mounting bracket 30 according to the embodiment of the present invention. Since the connection part 31 has the same configuration as the mounting bracket 30 described with reference to FIG. 3 except that the connection part 31 has two through holes 36, the description of the overlapping parts is omitted.

  The mounting bracket 30 includes a connection portion 31, an engagement portion 32a, and an engagement portion 32b. A through hole 36 a and a through hole 36 b are formed in the connection portion 31. The through hole 36 a and the through hole 36 b are arranged on the diagonal line of the connection portion 31. Therefore, when the screw is inserted into the through hole 36 a and the through hole 36 b and the attachment fitting 30 is attached to the attachment target W, it is possible to suppress the connection portion 31 from floating from the attachment target W. In particular, the deformation of the connection portion 31 can be suppressed when the weight of the lighting fixture 100 is applied to the mounting bracket 30, such as when the lighting fixture 100 is attached to the ceiling surface.
