The present invention relates to a method of installing an instrument using an auxiliary member.

Generally, to attach a fixture such as a downlight to a mounting hole in a ceiling material, insert the fixture into the mounting hole, place a part of the fixture behind the ceiling, and then mount the fixture (for example, a leaf spring). The fixture is attached to the mounting hole of the ceiling material by sandwiching the ceiling material in the thickness direction between the fixture and a part of the fixture (for example, a collar portion). However, the shape, thickness, material, etc. of the ceiling material at the periphery of the mounting hole are diverse. When the fixture does not correspond to the shape of the ceiling material (periphery of the mounting hole), a mounting assisting member that assists the mounting of the fixture on the ceiling material is used.

For example, Patent Document 1 discloses a downlight fixture mounting auxiliary member for mounting a downlight fixture to a ceiling material mounting hole regardless of the state of the inner edge of the ceiling material mounting hole. In Patent Document 1, the fixture body (10) of the downlight fixture has an outer flange (14) provided on the outer periphery of the outer edge of the opening of the housing (12) and an upward spreading angle to the outside of the housing (12). It has a pair of mounting springs (16a, 16b) installed, and a lamp (15) is mounted inside the hollow. The mounting auxiliary plate (30) has a through hole (32) formed in the center through which the housing (12) can be inserted, and has a cut portion (34) cut over a width (w) equal to or greater than the thickness of the ceiling material. It is formed in a C shape. Then, in order to fix the fixture body (10) to the ceiling material (18), first, the mounting auxiliary plate (30) is inserted into the mounting hole (20) of the ceiling material (18), and then into the back side mounting portion (18b). Fix it. Next, the instrument body (10) is pushed into the mounting hole (20) and the through hole (32) in a state where the mounting springs (16a, 16b) are pushed toward the housing (12) and bent. Then, the mounting springs (16a, 16b) inserted into the mounting holes (20) and the through holes (32) return outward to complete the mounting. The reference numerals of Patent Document 1 are shown in parentheses.

The mounting assisting member 100 of the embodiment of the present invention is configured to assist the mounting of the appliance in the mounting holes formed in the ceiling material. More specifically, the mounting auxiliary member 100 has a downlight fixture 15 (FIG. 7) with respect to the mounting holes 12 formed in the ceiling material 11 having a plurality of ridges 13 on the back surface side, as shown in FIG. See) to assist in mounting. Then, in the present embodiment, the structure in which the downlight fixture 15 is installed in the mounting hole 12 of the ceiling material 11 by using the mounting auxiliary member 100 is referred to as a fixture installation structure 10 (see FIGS. 8 to 10).

First, the mounting auxiliary member 100 will be described in detail with reference to FIGS. 1 to 5. 1 (a) and 1 (b) are a perspective view seen from above and a perspective view seen from below of the mounting auxiliary member 100 of one embodiment. 2 (a) to 2 (d) are a plan view, a front view, a side view, and a bottom view of the mounting auxiliary member 100. 3 (a) and 3 (b) are a cross-sectional view taken along the line AA and a cross-sectional view taken along the line BB of the mounting auxiliary member 100. 4 (a) and 4 (b) are a perspective view seen from above and a perspective view seen from below of the mounting auxiliary member 100 in a folded and deformed form. 5 (a) to 5 (d) are a plan view, a front view, a side view, and a bottom view of the mounting auxiliary member 100 in a folded and deformed form.

As shown in FIGS. 1 to 3, the mounting auxiliary member 100 includes a main body 101 formed in an annular shape in a plan view, and an avoidance recess 108 recessed in a part of the main body 101. The main body 101 is formed in an annular shape by joining a pair of C-shaped or semi-arc-shaped divided bodies 101a1 and 101a2. Further, the main body 101 forms a through hole 101b that communicates with the mounting hole 12 (see FIG. 6) of the ceiling material 11 inside the annulus.

On the lower surface of the main body 101, a contact portion 102 that comes into contact with the peripheral edge of the mounting hole 12 from the back surface side of the ceiling material 11 is provided. That is, the outer diameter of the main body 101 is at least larger than the inner diameter of the mounting hole 12 so that the contact portion 102 can come into contact with the peripheral edge of the mounting hole 12. In the present embodiment, the inner diameter of the main body 101 (through hole 101b) and the inner diameter of the mounting hole 12 are defined to be substantially equal to each other. A receiving portion 103 for receiving the elastic piece 18 (see FIG. 7) of the downlight fixture 15 is provided on the upper surface of the main body portion 101. In addition, a plurality of overhanging portions 107 project from the outer peripheral side surface of the main body portion 101. The operator can operate the mounting auxiliary member 100 by grasping the overhanging portion 107. In the present embodiment, one split body 101a1 is provided with two overhanging portions 107, and the other split body 101a2 is provided with one overhanging portion 107. A relatively wide flat portion 111 is formed by the lower surface of each overhanging portion 107 and a part of the lower surface of the abutting portion 102 (continuously provided to the overhanging portion 107). The flat portion 111 can be utilized as an arrangement space for fixing means for fixing the mounting auxiliary member 100 to the peripheral edge of the mounting hole 12. In particular, the overhanging portion 107 can secure a relatively wide area to which the double-sided tape is attached. Further, the inner peripheral surface of the main body 101 is cut out between the two overhanging portions 107 of one of the divided bodies 101a1, and the main body 101 has an L-shaped cross section. The wall portion of the main body 101 on the receiving portion 103 side of the L-shaped cross-sectional portion is easy for the operator to pinch and can function as the knob portion 112.

The main body 101 is configured to have a thickness (distance between the contact portion 102 and the receiving portion 103) that is sandwiched together with the ceiling material 11 by the sandwiching portion (flange portion 17, elastic piece 18) of the downlight fixture 15. Has been done. It is preferable that the thickness of the main body 101 (about 10 mm in the present embodiment) is set to be substantially equal to or larger than the thickness that can be sandwiched by the sandwiching portion of the downlight fixture 15 described later. However, the total thickness of the main body 101 and the ceiling material 11 may at least exceed the thickness of the plate material that can be sandwiched or pressed by the sandwiching portion. That is, the thickness of the main body 101 of the present invention can be appropriately set based on the thickness of the ceiling material and the thickness that can be sandwiched between the sandwiching portions.

Further, the mounting auxiliary member 100 is formed with an avoidance recess 108 recessed in a part of the contact portion 102 in order to avoid the ridge 13 in a state where the contact portion 102 is in contact with the peripheral edge of the mounting hole 12. ing. The avoidance recesses 108 are formed adjacent to the contact portion 102 in the circumferential direction of the main body portion 101, and are provided at two locations facing each other with the through hole 101b interposed therebetween. That is, in the present embodiment, a pair of avoidance recesses 108 arranged in a straight line are provided so that one ridge 13 can be straddled. The avoidance recess 108 is a pair of an upper wall 108a extending in the circumferential direction of the main body 101 with a predetermined length and a pair extending at a predetermined height in the thickness direction of the main body 101 so as to extend from both ends of the upper wall 108a. It is defined as a substantially rectangular recess by the opposite side wall 108b. The upper wall 108a is thinner than the thickness of the main body 101, and is formed so as to bulge upward from the upper surface of the receiving portion 103. Further, the upper wall 108a is connected to the upper surface of the receiving portion 103 by a triangular rib 108c. That is, the avoidance recess 108 extends along the circumferential direction of the main body 101 with a predetermined length, and the length is defined to be larger than the width of the ridge 13 of the ceiling material 11. Further, the avoidance recess 108 retracts upward from the contact portion 102 at a predetermined height, and the height thereof is set to be larger than the height of the ridge 13 of the ceiling material 11. That is, the mounting auxiliary member 100 is configured to be mounted on the back surface of the ceiling 11 across the ridge 13 via the avoidance recess 108.

The pair of divided bodies 101a1 and 101a2 constituting the main body 101 are rotatably connected via a hinge portion 104. Then, the main body 101 passes through the mounting holes 12 by displacing the relative positions of the divided bodies 101a and 101a2 from the first form (forms of FIGS. 1 to 3) capable of contacting the peripheral edge of the mounting holes 12. It can be transformed into a possible second form (the form shown in FIGS. 4 to 5). That is, since the outer diameter of the annular main body 101 is larger than the inner diameter of the mounting hole 12, the annular first form cannot pass through the mounting hole 12. Therefore, the second form may be selected when the mounting auxiliary member 100 is passed through the mounting hole 12.

Specifically, the hinge portion 104 is provided at a position in the main body portion 101 where the avoidance recess 108 is formed. The hinge portion 104 is a groove that radially traverses substantially the center of the upper wall 108a that defines the avoidance recess 108. Further, the groove of the hinge portion 104 is opened or recessed on the lower surface side (contact portion 102 side). Therefore, the pair of divided bodies 101a1 and 101a2 can preferentially rotate in the direction in which the upper surfaces (receiving portions 103) are close to each other. An engaging convex portion 105 and an engaging concave portion 106 are provided on both sides of the hinge portion 104 on the upper wall 108a. The engaging convex portion 105 is a protrusion protruding from the upper wall 108a, and the engaging concave portion 106 is a hole or a recess into which the engaging convex portion 105 can be fitted. The engaging convex portion 105 and the engaging concave portion 106 are arranged symmetrically with respect to the hinge portion 104, respectively.

Then, when the pair of divided bodies 101a1 and 101a2 are rotated so as to be folded from the annular first form shown in FIGS. 1 to 3, the mounting auxiliary member 100 has a C-shape as shown in FIGS. 4 and 5. Transforms into the second form of. In the second form, the pair of divided bodies 101a1, 101a2 are folded with the hinge portion 104 as a boundary, the upper surfaces of the receiving portions 103 of the divided bodies 101a1, 101a2 face each other substantially in parallel, and the upper surface of the upper wall 108a is in contact with the upper surface. I'm in contact. At this time, the engaging convex portion 105 is frictionally engaged with the engaging concave portion 106. The second form is simply maintained by the frictional force due to this fitting. Since the fitting of the engaging convex portion 105 and the engaging concave portion 106 due to such friction can be easily released, the mounting auxiliary member 100 can be easily deformed from the second form to the first form.

Next, with reference to FIG. 6, the structure of the ceiling material 11 constituting the appliance installation structure 10 of the present embodiment will be described. The ceiling material 11 of the present embodiment is generally made of a metal plate called a spandrel, and is formed relatively thinly. The thickness of the ceiling material 11 (about 1 mm in the present embodiment) is significantly thinner than the thickness that can be sandwiched by the sandwiching portion (flange portion 17, elastic piece 18) of the downlight fixture 15 described later. Further, the ceiling material 11 is provided with a plurality of (or one) ridges 13 projecting on the back surface side. The plurality of ridges 13 extend substantially in parallel at equal intervals. Each ridge 13 is formed by bending a steel plate, and improves the appearance and strength of the ceiling material 11. The ridge 13 has a uniform cross section in the longitudinal direction, and is formed in a U shape with a predetermined width and height in the cross section thereof. Further, the ceiling material 11 is provided with a plurality of mounting holes 12 for installing the downlight fixture 15. Each mounting hole 12 is formed as a circular hole centered on the center of the ridge 13 in the width direction. That is, the mounting hole 12 is bored so as to cut out one ridge 13. In the ceiling material 11 of the present embodiment, the diameter of the mounting hole 12 is larger than the width of the ridge 13, and the radius of the mounting hole 12 is smaller than the distance between the centers of the ridge 13. Therefore, the mounting hole 12 is formed so as to divide one ridge 13 without reaching the adjacent ridge 13.

The structure of the downlight fixture 15 constituting the fixture installation structure 10 of the present embodiment will be described with reference to FIG. 7. As shown in FIG. 7, the downlight fixture 15 includes a fixture main body 16 in which an electric lamp such as an LED bulb is installed, and an annular flange portion 17 projecting laterally from the lower surface (illuminated side end face) of the fixture main body 16. Be prepared. Then, a pair of leaf spring-shaped elastic pieces 18 extend laterally from the back surface side base end of the flange portion 17 of the instrument main body 16. The elastic piece 18 extends at an angle close to the collar portion 17, and is elastically deformable in a direction (upward) away from the collar portion 17. It is possible to sandwich a plate material (periphery of the mounting hole 12 of the ceiling material 11) having a predetermined thickness between the elastic piece 18 elastically deformed in the separation direction and the flange portion 17 by elastic force. That is, the collar portion 17 and the elastic piece 18 cooperate with each other to function as a holding portion. In the present embodiment, the thickness of the plate material that can be practically sandwiched or pressed by the sandwiching portion (flange portion 17, elastic piece 18) is at least about 9 mm, and the main body portion 101 can be sandwiched. The downlight fixture 15 described here is merely an example of the fixture, and the shape and form of the downlight fixture 15 does not matter as long as it is a general fixture or a lighting fixture of the type in which the plate material is sandwiched between the sandwiching portions. Further, the elastic piece of the holding portion is not limited to the leaf spring, and may be an inelastic member such as a claw. Further, the direction of "holding" is not necessarily limited to the direction perpendicular to the ceiling material 11, and the holding pressure may be applied so that the holding portion of the appliance spreads outward.

Next, with reference to FIGS. 8 to 11, the fixture installation structure 10 in which the downlight fixture 15 is installed in the mounting hole 12 of the ceiling material 11 by using the mounting auxiliary member 100 of the present embodiment will be described. FIG. 8 is a schematic perspective view of the instrument installation structure 10. FIG. 9 is a plan view of the instrument installation structure 10. FIG. 10 is a schematic cross-sectional view taken along the line CC of the instrument installation structure 10. FIG. 11 is a schematic DD cross-sectional view of the instrument installation structure 10. In the schematic cross-sectional view, the inside of the fixture body 16 of the downlight fixture 15 is not shown as a cross section for convenience of explanation.

As shown in FIGS. 8 and 9, in the fixture installation structure 10, the fixture main body 16 of the downlight fixture 15 is housed in the mounting hole 12 of the ceiling member 11. Further, the annular mounting auxiliary member 100 is placed on the back surface of the ceiling material 11. At this time, the mounting auxiliary member 100 is arranged so as to straddle the ridge 13. The downlight fixture 15 is installed on the ceiling member 11 by sandwiching the ceiling member 11 and the mounting auxiliary member 100 between the pair of elastic pieces 18 and the flange portion 17 of the downlight fixture 15.

More specifically, as shown in FIG. 10, the upper portion of the housing of the fixture main body 16 extends toward the back surface side of the ceiling material 11 in a state where the upper surface of the flange portion 17 is in contact with the surface surface of the ceiling material 11. On the other hand, the contact portion 102 of the mounting auxiliary member 100 is in contact with the peripheral edge of the mounting hole 12 from the back surface of the ceiling material 11. At this time, the through hole 101b of the mounting auxiliary member 100 and the mounting hole 12 communicate with each other, and the center and the inner peripheral edge thereof are substantially aligned with each other. In the present embodiment, the mounting auxiliary member 100 is fixed to the peripheral edge of the mounting hole 12 via a double-sided tape (not shown) provided in a part of the contact portion 102. Then, the elastic piece 18 extends from the upper surface of the flange portion 17 to the back surface side of the ceiling material 11 through the mounting hole 12. The elastic piece 18 is at least in contact with the receiving portion 103 of the mounting auxiliary member 100 and is elastically deformed upward (on the back surface side of the ceiling material). That is, the elastic piece 18 is elastically deformed so as to rotate upward from the initial state of FIG. 7. Then, the elastic recovery force of the elastic piece 18 acts on the receiving portion 103, so that the ceiling member 11 (mounting hole 12 peripheral edge) and the mounting auxiliary member 100 (main body portion 101) are combined by the flange portion 17 and the elastic piece 18. It is pinched. That is, in the appliance installation structure 10, the thickness of the ceiling material 11 is increased by the thickness of the main body 101, so that the elastic force of the elastic piece 18 is sufficiently exhibited. In other words, the elastic deformation of the elastic piece 18 is insufficient only by the thickness of the ceiling material 11, and the ceiling material 11 cannot be firmly sandwiched between the flange portion 17 and the elastic piece 18 without the mounting auxiliary member 100. As a result, the downlight fixture 15 is stably attached to the attachment hole 12 of the ceiling material 11.

Further, the downlight fixture 15 is attached to a mounting hole 12 that divides a ridge 13 projecting to the back surface side of the ceiling material 11. That is, ridges 13 are formed on the periphery of the mounting hole 12 at two locations facing each other with the mounting hole 12 in between. On the other hand, the mounting auxiliary member 100 is provided with avoidance recesses 108 from the contact portion 102 at two positions facing each other with the through hole 101b interposed therebetween. As shown in FIG. 11, the abutting portion 102 is in contact with the peripheral edge of the mounting hole 12 by passing the straight ridges 13 through a pair of avoiding recesses 108 aligned in a straight line. In other words, by accommodating the ridges 13 in the pair of avoidance recesses 108, the mounting auxiliary member 100 is stably fixed to the peripheral edge of the mounting holes 12 so as to straddle the ridges 13.

Subsequently, with reference to FIGS. 12 and 13, a method of constructing the fixture installation structure 10 of the present embodiment, that is, a downlight fixture 15 having a sandwiching portion for sandwiching the ceiling material 11 in the thickness direction is provided with a mounting hole 12. The method of fixing through is described.

First, the mounting auxiliary member 100 is prepared, and as shown in FIG. 12A, the mounting auxiliary member 100 is folded on the surface side of the ceiling material 11 and deformed into the second form. Specifically, the pair of divided bodies 101a and 101a are relatively rotated in the direction in which the receiving portion 103 is close to the hinge portion 104, and the engaging convex portion 105 and the engaging concave portion 106 are frictionally fitted. By doing so, the main body 101 is folded. Next, while gripping the overhanging portion 107 or the knob portion 112, the mounting auxiliary member 100 deformed into a C shape through the mounting hole 12 is inserted from the front surface side to the back surface side of the ceiling material 11. At this time, it is preferable to pinch the knob portion 112 and insert and arrange the mounting auxiliary member 100 on the back surface of the ceiling material 11. That is, when the double-sided tape is provided in advance on the flat portion 111 on the lower surface of the overhanging portion 107, the operator can touch and stain the double-sided tape by utilizing the knob portion 112 to reduce the adhesive force. Can be prevented. Although the outer diameter of the main body 101 of the mounting auxiliary member 100 is larger than the diameter of the mounting hole 12, the mounting auxiliary member 100 can be easily arranged on the back surface side of the ceiling material 11 by folding it in half in this way. Can be done. Further, since the mounting auxiliary member 100 of the second form is relatively compact, it is easy to handle on the back surface side of the ceiling material 11.

Next, as shown in FIG. 12B, the frictional engagement between the engaging convex portion 105 and the engaging concave portion 106 is released, and the mounting auxiliary member 100 is expanded from the second form on the back surface side of the ceiling material 11 to the second. It is transformed into one form, and the mounting auxiliary member 100 is arranged on the peripheral edge of the mounting hole 12 so as to straddle the ridge 13 via the avoidance recess 108. Preferably, in the state where the mounting auxiliary member 100 is folded, one of the divided bodies 101a1 is fixed to one side with the ridge 13 on the periphery of the mounting hole 12 as a boundary with double-sided tape, and then mounted while gripping the overhanging portion 107. The auxiliary member 100 is deformed into the first form, and the other split body 101a2 is fixed to the other side of the mounting hole 12 with the ridge 13 as a boundary with double-sided tape. As a result, the ridge 13 is accommodated in the avoidance recess 108, the mounting hole 12 and the through hole 101b are matched, and the mounting auxiliary member 100 can be easily fixed on the peripheral edge of the mounting hole 12. A magnet (magnetic attachment) may be used instead of the double-sided tape (adhesion) as the position fixing means. In this way, the mounting auxiliary member 100 can be installed on the back surface of the ceiling material 11 to increase the thickness of the peripheral edge of the mounting hole 12.

Then, as shown in FIG. 13, the downlight fixture 15 (not shown, but wired to the power supply or the like) is inserted from the surface side of the ceiling material 11 toward the mounting hole 12 and the through hole 101b. Specifically, when the upper part of the instrument body 16 is inserted into the mounting hole 12, the elastic piece 18 is elastically deformed upward and inward so that the instrument body 16 is not brought into contact with the peripheral edge of the mounting hole 12. It can be passed through the mounting hole 12. Then, when the fixture body 16 is inserted until the upper surface of the flange portion 17 of the downlight fixture 15 abuts on the surface of the ceiling material 11, the elastic piece 18 partially rotates downward and abuts on the receiving portion 103. At this time, since the elastic piece 18 is still in an elastically deformed state, the elastic piece 18 urges the receiving portion 103 downward. In this way, the downlight fixture 15 can be installed in the mounting hole 12 of the ceiling material 11 by sandwiching the ceiling material 11 and the mounting auxiliary member 100 between the elastic piece 18 and the flange portion 17. Note that the method described here is only an example, and a person skilled in the art can change the order of each step, or omit or change unnecessary steps depending on the situation.

Hereinafter, the action and effect of the mounting auxiliary member 100 according to the embodiment of the present invention will be described.

According to the mounting auxiliary member 100 of the present embodiment, the main body 101 is a ceiling material with the holding portions 17 and 18 of the downlight fixture 15 in a state where the contact portion 102 is in contact with the peripheral edge of the mounting hole 12 of the ceiling material 11. It has a thickness that can be sandwiched together with 11. That is, the thickness of the main body 101 is determined so that the total thickness of the ceiling material 11 and the thickness of the main body 101 reaches the thickness that can be held by the holding portions 17 and 18 of the downlight fixture 15. As a result, the downlight fixture 15 can be attached to the mounting hole 12 of the ceiling material 11 via the mounting auxiliary member 100 regardless of the thickness of the ceiling material 11. Further, since a pair of avoidance recesses 108 are recessed in a part of the contact portion 102, the straight ridge 13 of the ceiling material 11 is provided with the contact portion 102 in contact with the peripheral edge of the mounting hole 12. It is possible to mount the main body 101 on the periphery of the mounting hole 12 so as to avoid the above. Therefore, by using the mounting auxiliary member 100 of the present embodiment, it is possible to easily mount the downlight fixture 15 on the ceiling material 11 having the ridge 13. That is, the mounting auxiliary member 100 of the present embodiment reliably assists the mounting of the downlight fixture 15 on the ceiling member 11 which is thin and has the ridges 13 protruding on the back surface side.

[Modification example]
The present invention is not limited to the above embodiment, and various modifications can be taken. Hereinafter, modifications of the present invention will be described. In each modification, the components having the last two digits in common among the components represented by the three digits have the same or similar characteristics unless otherwise explained, and some of the description thereof will be omitted.

(1) In the mounting auxiliary member 100 of the above embodiment, the two divided bodies 101a1 and 101a2 can be relatively displaced by the hinge portion 104 provided on the upper wall 108a of the avoidance recess 108, but the present invention is not limited thereto. .. For example, the hinge portion may be provided at a location other than the upper wall of the avoidance recess. Further, instead of providing the hinge portion, the two divided bodies may be partially or completely detachable. Further, the mounting auxiliary member of the present invention may be composed of three or more divided bodies. Further, in the above embodiment, the two divided bodies 101a1 and 101a2 are completely folded so as to overlap each other, but may be folded in a V shape as long as they can pass through the mounting holes. A modified example of the present invention will be specifically illustrated below.

For example, the mounting auxiliary member 200 shown in FIG. 14 has a through hole 201b communicating with the mounting hole 22 and has a contact portion 202 that abuts from the back surface side of the ceiling material 21 to the peripheral edge of the mounting hole 22. In a state where the main body portion 201 having a thickness to be sandwiched together with the ceiling material 21 by the sandwiching portion of the above and the contact portion 202 are in contact with the peripheral edge of the mounting hole 22, the contact portion 202 is partly formed in order to avoid the ridge 23. It is provided with a recessed avoidance recess 208. Unlike the mounting auxiliary member 100 of the above embodiment, the main body portion 201 of the mounting auxiliary member 200 is not a displaceable split body, but is formed in a C shape having a notch 209 in a part in the circumferential direction. .. The avoidance recess 208 and the notch 209 are located so as to face each other across the through hole 201b. Then, as shown in FIG. 14 (c), by tilting the mounting auxiliary member 200 so as to sandwich the ceiling material 21 in the notch portion 209, the mounting auxiliary member 200 is allowed to pass through the mounting hole 22, and the mounting auxiliary member 200 is passed. The ceiling material 21 can be moved from the front surface side to the back surface side. In this modification, the mounting auxiliary member 200 can be installed on the ceiling material 21 so as to straddle the ridge 23 via the avoidance recess 208 and the notch 209. However, since the main body 201 of this modification is C-shaped, it is easily bent and deformed so that the notch 209 expands. Therefore, in the case of a type in which the holding pressure is applied so that the holding portion of the downlight fixture spreads outward, the ring shape in which the notch portion 209 is connected (as in the mounting auxiliary member 100 of the above embodiment) is used. However, it is suitable because the shape of the mounting auxiliary member is stable.

For example, the mounting auxiliary member 300 shown in FIG. 15 has a through hole 301b that communicates with the mounting hole, has a contact portion 302 that abuts on the peripheral edge of the mounting hole from the back surface side of the ceiling material, and has a holding portion of the downlight fixture. A pair of a main body portion 301 having a thickness to be sandwiched together with the ceiling material and a pair of recessed portions in a part of the contact portion 302 in order to avoid ridges in a state where the contact portion 302 is in contact with the peripheral edge of the mounting hole. It is provided with an avoidance recess 308. Unlike the mounting auxiliary member 100 of the above embodiment, the mounting auxiliary member 300 of this modification has a bellows-shaped upper wall 308a that defines the avoidance recess 308. By bending or refracting the bellows-shaped upper wall 308a, both the divided bodies 301a1 and 301a2 can be tilted with each other and deformed into a form capable of passing through the mounting hole.

(2) In the above embodiment, in the ceiling material, a circular mounting hole is formed in the center of the ridge in the width direction, and the mounting hole has only one ridge cut out. Not limited to. For example, in the ceiling material, the mounting holes may be large enough to extend to a plurality of adjacent ridges. In that case, it can be dealt with by forming a plurality of pairs of avoidance recesses that are linearly aligned according to the number of ridges in the mounting auxiliary member. Alternatively, the shape of the mounting hole may be another shape such as a square shape instead of a circular shape. In that case, it can be dealt with by changing the outer shape of the mounting auxiliary member according to the shape of the mounting hole. Alternatively, the ridges may be bent or refracted in the ceiling material. In that case, it is possible to shift the position of the avoiding recess of the mounting auxiliary member from the facing position according to the refraction angle of the ridge. That is, the above embodiment is only one embodiment exemplifying the present invention, and if it is within the technical scope of the present invention, the mounting auxiliary member and the fixture installation structure are used according to the shape and type of the ceiling material and the fixture. The form of is appropriately modified.

(3) In the above embodiment, the mounting auxiliary member is used for assisting in mounting the fixture on the thin ceiling material, but the use is not limited to the embodiment. For example, it may be used to reinforce the brittle mounting hole peripheral edge of the ceiling material or to change the diameter of the mounting hole.

The present invention is not limited to the above-described embodiments and modifications, and can be implemented in various embodiments as long as it belongs to the technical scope of the present invention.
