(Configuration of the decorative frame device 1000)
As shown in FIGS. 1 and 2, the decorative frame device 1000 attached to the ceiling board 400 includes a decorative frame unit 100 and a back plate 200.

(Downlight 300)
The downlight 300 shown in FIG. 1 and the like is adapted to a hole of φ150 (hereinafter, the unit of the hole diameter is mm). The downlight 300 has a circular flange portion 310 formed at the light irradiation port. The outer diameter of the flange outer peripheral portion 301 (FIGS. 1 and 2) is φ170 (φF) (FIG. 1). The downlight 300 has a leaf spring 320 at the flange portion 310, and is attached to the through hole 101 of the decorative frame 110 by the leaf spring 320. Further, the downlight 300 has heat radiation fins 330.

(Decorative frame unit 100)
The decorative frame unit 100 includes a decorative frame 110 in which a through hole 101 (φ150) is formed, frame fixing brackets 120 (three in the figure), and a top plate 130. As shown in FIG. 2, a slide fitting groove 150 is formed in each of the three frame fixing fittings 120 (stands), and the slide fitting 140 (pressing pressure portion) is formed in the slide fitting groove 150. It is attached.

(Configuration of the decorative frame device 1000)
The configuration of the decorative frame device 1000 will be described. Description will be made assuming that the downlight 300 for the embedded hole diameter φA (φ150) is attached to the ceiling plate 400 having an opening diameter φB (φB = φ200) larger than the embedded hole diameter φA.
First, the dimensional relationships of the through holes 401 and the like of the ceiling board 400 are summarized.
(1) A: Diameter φA = φ150 of the through hole 101 (three through holes) of the decorative frame 110,
(2) B: Diameter φB = φ200 of the through hole 401 (one through hole) of the ceiling plate 400,
(3) C: Diameter φC = φ175 of the through hole 201 (two through holes) of the back plate 200,
(4) E: outer diameter of the decorative frame 110 φE = φ300,
(5) F: The diameter φF = φ170 of the outer periphery of the flange of the downlight 300 is set.
The size relationship of the through holes is through hole 101 (φA) <through hole 201 (φC) <through hole 401 (φB). Further, the through hole 401 (φB) <the outer diameter φE of the decorative frame 110. Further, the through hole 101 (φA) <the flange outer peripheral diameter of the downlight 300 (φF). Thus, in the following, the downlight 300 is attached to the ceiling plate 400 having a hole diameter of φ150 (compatible hole diameter). However, since the ceiling plate 400 has the hole diameter of φ200, the downlight 300 has the same hole diameter as that of the downlight 300. not compatible. For this reason, the case where the downlight 300 is attached to the ceiling board 400 using the decorative frame apparatus 1000 is demonstrated.

(Decorative frame 110)
The decorative frame 110 is a flat plate-like member in which a through hole 101 (φA) into which the downlight 300 is inserted is formed. That is, as shown in FIG. 1, the decorative frame 110 has a disk shape (outer diameter φE), and a through hole 101 (φA) that is a circular opening is formed substantially concentrically with the outer diameter φE. . The diameter φA (inner diameter) of the through hole 101 is φA = φ150. That is, the diameter A of the through hole 101 is a dimension suitable for the downlight 300 for the embedded hole diameter φ150. Further, the outer diameter φE of the decorative frame 110 is larger than the diameter φB of the through hole 401 of the ceiling plate 400. That is, the through hole φB is closed with the outer diameter φE of the decorative frame 110 (FIG. 1). Further, the outer diameter φF (φ170) of the flange outer peripheral portion 301 is larger than the diameter φA (φ150) of the through hole 101 of the decorative frame 110.

(Frame fixing bracket 120)
As shown in FIG. 2, the frame fixing bracket 120 is disposed on the decorative frame 110 at a position larger than the through hole 101 (periphery of the upper surface 110-1 of the through hole 101). The frame fixing bracket 120 is vertically fixed to the decorative frame 110 by spot welding or screws. Thus, the frame fixing bracket 120 is a plate-like member that stands up from the vicinity of the periphery of the through hole 101 of the upper surface 110-1 (the surface on the ceiling plate side) of the decorative frame 110. Two or more frame fixing brackets 120 are arranged. The frame fixing bracket 120 is a rectangular flat plate having a substantially U-shaped horizontal cross section, and stands up from the vicinity of the peripheral edge of the through hole 101 on the upper surface 110-1 of the decorative frame 110. The frame fixture 120 is provided with a slide fitting groove 150 in the longitudinal direction (standing direction). The frame fixing bracket 120 includes a slide bracket 140 that slides the slide bracket groove 150 up and down in the upright direction. When the slide fitting 140 is lowered, the ceiling plate 400 (manufacturing material) is sandwiched between the decorative frame 110 and the back plate 200 and pressed down, so that the decorative frame 110 does not fall off the mounting surface.

(Top plate 130)
The decorative frame unit 100 includes a top plate 130 to which the tips of the respective frame fixing brackets 120 are connected. The top plate 130 (FIG. 2) is fixed to the frame fixing bracket 120 with a spot or a screw so that the frame fixing bracket 120 is fixed to the decorative frame 110 vertically and to prevent the frame fixing bracket 120 from being deformed. It is fixed. The top plate 130 is smaller in size than the through hole 201 (φ175) of the back plate 200. That is, as shown in FIG. 2, when viewed in the Y direction from the top to the bottom (the laminating direction described later) (when the decorative frame unit 100 is looked down from directly above), the frame fixing bracket 120 and the top plate 130 are formed of the through holes 101. It falls within a virtual circle having a diameter φG (φG <φC) concentric with (φ150). For example, φG = 160. Therefore, the frame fixing bracket 120 and the top plate 130 can pass through the through hole 401 and the through hole 201.

(Back plate 200)
The back plate 200 has a substantially rectangular flat plate shape having a through hole 201 (φC = φ175) into which the frame fixing metal fitting 120 and the top plate 130 are inserted at substantially the center. Further, in order to increase the strength, a box shape or a substantially U shape may be used. The length W1 (FIGS. 2 and 6) in the short direction of the back plate 200 is shorter than the diameter φB (φ200) of the through hole 401 formed in the ceiling plate 400 serving as a mounting surface, and the through hole of the decorative frame 110 101 is longer than the diameter φA (φ150). Further, the through hole 201 of the back plate 200 is such that the frame fixing bracket 120 and the top plate 130 can pass through, and is slightly larger (φ175) than the diameter φA (φ150) of the through hole 101. Since the length W1 in the short direction is shorter than the diameter φB (φ200) of the through hole 401, the back plate 200 can be inserted from the indoor side to the ceiling back (the upper surface 400-1 side of the ceiling plate 400). Further, the length W2 in the longitudinal direction of the back plate 200 is larger than the diameter φB of the through hole 401 of the ceiling plate 400 serving as a mounting surface.

(Effects of dimensions of W1 and W2)
As shown in FIG. 6, by defining the length W2 in the longitudinal direction and the length W1 in the short direction of the back plate 200, the back plate 200 can be inserted into the ceiling from below. Furthermore, even if the back plate 200 is placed on the back of the ceiling, the back plate 200 does not fall from the ceiling plate 400 because the length W2 in the longitudinal direction is larger than the through hole 201.

(Back plate fixing bracket 210)
As shown in FIG. 2, a groove that is long in the Z direction from the center (near the periphery) to the outer side (short side) along the longitudinal direction of the back plate 200 along the periphery of the through hole 201 (φ175) of the back plate 200. 202 is provided. A back plate fixing bracket 210 (auxiliary plate fixing portion) is disposed in the groove 202.

  For example, the back plate fixing bracket 210 has a screw attached to a plate in which a screw hole is formed on the plate, and can freely slide in the groove 202 of the back plate. Then, by tightening the screw, the screw back plate fixing bracket 210 can be fixed at the slide position. Alternatively, an elastic “spring material 211” (drawn larger in FIG. 2) formed in a “U-shape” having a width larger than the groove width W3 of the groove 202 is inserted into the groove 202 of the back plate 200. To do. Then, the groove 202 is slid freely with the width of the spring material 211 in a compressed state, the compression is released, and the spring material 211 is fixed at the position of the groove 202 by a spring restoring force. In this way, the back plate 200 is slid to the edge of the through hole 401 of the ceiling plate 400 by sliding the back plate fixing bracket 210 from the center (periphery of the through hole 201) outward (Y direction in FIG. 2). Can be fixed.

  The through-hole 401 of the ceiling plate 400 has been described as φB = φ200. However, the through-hole 401 is not limited to φ200. ), The back plate fixing bracket 210 can be slid linearly in the left and right (Z direction, anti-Z direction), so that the back plate 200 can be fixed to the ceiling plate 400.

  When φB of the through hole 401 of the ceiling plate 400 matches φC of the through hole 201 of the back plate 200, only the decorative frame unit 100 is used without using the back plate 200. In this case, simply by lowering the slide fitting 140 of the decorative frame unit 100, the decorative frame 110 and the slide fitting 140 sandwich the ceiling plate 400. Therefore, the decorative frame unit 100 can be attached to the ceiling board 400 as it is.
