Description

  TECHNICAL FIELD The present invention relates to a mounting auxiliary member for assisting attachment of an instrument to a mounting hole formed in a ceiling material.

  Generally, in order 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 portion of the fixture behind the ceiling, and then mount the fixture on the fixture (for example, a leaf spring). The ceiling material is clamped in the thickness direction by the and a part of the appliance (for example, a collar portion), so that the appliance is attached to the mounting hole of the ceiling material. However, the shape, thickness, material, etc. of the ceiling material at the periphery of the mounting hole are various. When the fixture does not correspond to the shape of the ceiling material (periphery of the mounting hole) or the like, a mounting auxiliary member that assists the mounting of the fixture on the ceiling material is used.

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

  However, for example, when the ceiling material is made of a thin material such as a spandrel, the ceiling material cannot be sufficiently clamped by the mounting spring of the downlight fixture. Even if the conventional mounting auxiliary plate is interposed between the mounting spring and the back surface of the ceiling material, since the mounting auxiliary plate is formed in a thin plate shape, the total thickness of the ceiling thickness and the mounting auxiliary plate is the equipment. The attachment spring is not thick enough to hold it, and the fixture cannot be firmly fixed to the ceiling material. Further, when the mounting auxiliary member is arranged on the ceiling material, it is necessary to position the mounting auxiliary member as accurately as possible so that the through hole of the mounting auxiliary plate and the mounting hole of the ceiling material are aligned with each other. However, since the work of positioning the mounting auxiliary member is generally performed on the back side of the ceiling material with the mounting hole inserted from the front side of the ceiling material, it cannot be visually checked and accurate positioning can be performed quickly. Was difficult. Therefore, there has been a problem that it is difficult to install the equipment on the ceiling material.

That is, the present invention is not limited to the dimensional ratios in the drawings.

  The attachment assisting member 100 according to the embodiment of the present invention is configured to assist the attachment of the device to the attachment hole formed in the ceiling material. More specifically, the attachment assisting member 100 assists in attaching the downlight fixture 15 (see FIG. 8) to the attachment hole 12 formed in the ceiling material 11. Then, in the present embodiment, a structure in which the downlight fixture 15 is installed in the attachment hole 12 of the ceiling material 11 using the attachment auxiliary member 100 is referred to as a fixture installation structure 10 (see FIGS. 9 to 11).

  First, the attachment assisting member 100 will be described in detail with reference to FIGS. 1 to 7. 1A and 1B are a perspective view of the attachment assisting member 100 of one embodiment as seen from above and a perspective view as seen from below. 2A to 2D are a plan view, a front view, a side view, and a bottom view of the mounting auxiliary member 100. 3A and 3B are an AA sectional view and a BB sectional view of the attachment assisting member 100. 4A and 4B are partially enlarged perspective views (extended state and stored state) of the protruding portion 108 of the attachment assisting member 100. 5A and 5B are schematic cross-sectional views (extended state and stored state) of the protruding portion 108. 6A and 6B are a perspective view of the mounting auxiliary member 100 in a folded and deformed form as seen from above and a perspective view as seen from below. 7A to 7D are a plan view, a front view, a side view, and a bottom view of the mounting auxiliary member 100 in the folded and deformed form.

  As shown in FIGS. 1 to 3, the attachment assisting member 100 includes a main body 101 formed in an annular shape in a plan view, and a protrusion 108 provided on the main body 101 so as to protrude toward the surface of the ceiling material 11. Equipped with. The main body 101 is formed in an annular shape by joining a pair of C-shaped or semi-circular arc-shaped divided bodies 101a1 and 101a2. Further, the main body portion 101 has a through hole 101b formed therein, which communicates with the mounting hole 12 (see FIG. 9) of the ceiling member 11 inside the ring.

  On the lower surface of the main body 101, an abutting portion 102 that abuts the peripheral edge of the mounting hole 12 from the rear 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 contact the periphery of the mounting hole 12. In this embodiment, the inner diameter of the main body 101 (the through hole 101b) and the inner diameter of the mounting hole 12 are set to be substantially equal to each other. A receiving portion 103 for receiving the elastic piece 18 (see FIG. 8) of the downlight fixture 15 is provided on the upper surface of the main body portion 101. Further, a plurality of projecting portions 107 project from the outer peripheral side surface of the main body 101. An operator can operate the attachment assisting member 100 by gripping the projecting portion 107. In the present embodiment, one divided body 101a1 is provided with two overhanging portions 107, and the other divided body 101a2 is provided with one overhanging portion 107. A relatively wide flat portion 111 is formed by the lower surface of each protruding portion 107 and a part of the lower surface of the contact portion 102 (continuously provided on the protruding portion 107). The flat portion 111 can be utilized as an arrangement space for fixing means for fixing the attachment auxiliary member 100 to the peripheral edge of the attachment hole 12. In particular, the protrusion of the protrusion 107 can secure a relatively wide double-sided tape attachment surface. In addition, the inner peripheral surface of the main body 101 is cut out between the two projecting portions 107 of the one divided body 101a1 so that the main body 101 has an L-shaped cross section. The wall portion on the receiving portion 103 side of the L-shaped cross section of the main body portion 101 is easy for an operator to grip, and can function as a 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 clamped together with the ceiling material 11 by the clamping portion (the collar portion 17 and the elastic piece 18) of the downlight fixture 15. Has been done. The thickness (about 10 mm in the present embodiment) of the main body 101 is preferably set to be substantially equal to or larger than the thickness that can be held by the holding portion of the downlight fixture 15 described later. However, it suffices that the total thickness of the main body portion 101 and the ceiling material 11 exceeds at least the thickness of the plate material that can be clamped or clamped by the clamping 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 held by the holding portion.

  As shown in FIG. 4A, the main body 101 is provided with a protruding portion 108 so as to protrude more toward the surface side of the ceiling material 11 than the contact portion 102. In this embodiment, the two protrusions 108 are formed only on one of the divided bodies 101a. Each projecting portion 108 hangs from the inner peripheral side edge of the contact portion 102 by a predetermined length. The length of the projecting portion 108 is longer than the thickness of the ceiling material 11, and is preferably a length protruding from the mounting hole 12 to the front side of the ceiling material 11 when placed on the periphery of the mounting hole 12 on the back surface of the ceiling material 11. . Further, the protruding portion 108 is a U-shaped thin plate piece closed at the tip, and is curved in an arc shape with substantially the same curvature as the inner peripheral surface of the main body portion 101 (and the peripheral edge of the mounting hole 12). There is. That is, the protruding portion 108 extends in the circumferential direction with a predetermined width along the inner peripheral side edge of the contact portion 102. That is, in the protruding portion 108, the position where the contact portion 102 contacts the peripheral edge of the mounting hole 12 (in particular, the centers of the through hole 101b and the mounting hole 12 are aligned, and the inner peripheral edge of the contact portion 102 and the mounting hole 12 are aligned. It is configured such that it can be engaged with the inner peripheral surface of the mounting hole 12 at a position where the peripheral edges are substantially aligned. Further, a hook-like engaging claw 108a is formed on the inner surface of the projecting portion 108 so as to project radially inward. As shown in FIG. 5A, the engaging claw 108a extends substantially vertically from the inner surface of the protruding portion 108, and a conical protrusion that is directed upward (toward the proximal end of the protruding portion 108) is formed at the tip thereof. Has been done.

  In addition, the protruding portion 108 is a second position (not shown) that does not protrude from the surface of the ceiling material 11 from the first position (the form of FIGS. 4A and 5A) that protrudes from the contact portion 102 to the surface side of the ceiling material 11 (FIG. 4 (b) and 5 (b)) is configured to be displaceable. The “first position projecting to the surface side of the ceiling material” of the present invention is, in addition to the form of projecting from the surface of the ceiling material together with the contact portion, as in the present embodiment, a ceiling material that projects from the contact portion. It is a concept including a form that does not protrude from the surface. That is, the attachment assisting member of the present invention exerts its function and effect without being influenced by the thickness of the ceiling material.

  The protruding portion 108 is connected to the main body 101 via a connecting portion 108b that is relatively thinner than the other portions. As a result, as shown in FIGS. 5A and 5B, the projecting portion 108 can be pivotally displaced so as to be folded back toward the main body 101 side using the connecting portion 108b as a hinge. In other words, the projecting portion 108 can be retracted or displaced from the projecting position at which it can be engaged with the inner peripheral surface of the mounting hole 12 so that the projecting length projecting from the contact portion 102 is reduced. On the other hand, the main body 101 is provided with a storage unit 109 that stores the folded back protrusion 108. The storage portion 109 is a recess provided in the inner peripheral surface of the main body portion 101 and corresponds to the shape of the protruding portion 108. A notch 109a is formed at the upper end of the storage portion 109 so that the engagement claw 108a of the protruding portion 108 can be received and locked there. The notch 109a is formed by notching the inner peripheral edge of the main body 101 on the receiving portion 103 side. Then, as shown in FIG. 5B, when the protrusion 108 is accommodated in the accommodating portion 109, the protrusion at the tip of the engaging claw 108a is caught by the inner wall of the main body 101 in the notch 109a, and thus the protrusion 108 may be retained within the storage 109. That is, the engaging claw 108a and the notch 109a function as a holding portion that holds the protruding portion 108 at the second position.

  The pair of divided bodies 101a1 and 101a2 forming the main body 101 are pivotally connected via a hinge 104. Then, the main body portion 101 passes through the mounting hole 12 by displacing the relative position of each of the divided bodies 101a and 101a2 from the first mode (the mode of FIGS. 1 to 3) capable of contacting the periphery of the mounting hole 12. It can be modified into a possible second form (forms of FIGS. 6 to 7). That is, since the outer diameter of the ring-shaped main body 101 is larger than the inner diameter of the mounting hole 12, the ring-shaped first form cannot pass through the mounting hole 12. Therefore, the second mode can be selected when the attachment assisting member 100 is passed through the attachment hole 12.

  Specifically, the pair of hinge portions 104 are provided at positions along the radial direction of the main body portion 101. The hinge portion 104 is a groove that traverses the main body portion 101 in the radial direction. 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 are preferentially rotatable in the directions in which the upper surfaces (receiving portions 103) are close to each other. Then, an engaging convex portion 105 and an engaging concave portion 106 are provided on both sides of the hinge portion 104. The engaging convex portion 105 is a protrusion protruding from the upper surface of the main body 101, 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 at symmetrical positions with the hinge portion 104 as the center.

  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 attachment assisting member 100 is C-shaped as shown in FIGS. 6 and 7. To the second form. In the second embodiment, the pair of divided bodies 101a1 and 101a2 are folded around the hinge portion 104, and the upper surfaces (receiving portions 103) of the divided bodies 101a1 and 101a2 are in contact with each other. At this time, the engagement protrusion 105 is frictionally engaged with the engagement recess 106. The second form is simply maintained by the frictional force due to this fitting. Since the fitting between the engaging convex portion 105 and the engaging concave portion 106 due to such friction can be easily released, the attachment assisting member 100 can be easily deformed from the second form to the first form.

  Next, the structure of the ceiling material 11 that constitutes the fixture installation structure 10 of the present embodiment will be described. The ceiling material 11 of this embodiment is made of a metal plate and is formed to be relatively thin. The thickness of the ceiling material 11 (about 1 mm in the present embodiment) is significantly smaller than the thickness that can be sandwiched by the sandwiching portion (the collar portion 17 and the elastic piece 18) of the downlight fixture 15 described later. The ceiling material 11 is merely an example, and its material, thickness, and the like can be arbitrarily changed.

  With reference to FIG. 8, the structure of the downlight fixture 15 that constitutes the fixture installation structure 10 of the present embodiment will be described. As shown in FIG. 8, the downlight fixture 15 includes a fixture main body 16 in which an electric light such as an LED bulb is housed, and an annular collar portion 17 which laterally projects from the lower face (illumination side end face) of the fixture main body 16. Prepare A pair of leaf spring-like elastic pieces 18 extend laterally from the rear end of the flange portion 17 of the instrument body 16. The elastic piece 18 extends at an angle close to the flange portion 17, and is elastically deformable in a direction (upward) away from the flange portion 17. The elastic piece 18 elastically deformed in the separating direction and the flange portion 17 can sandwich a plate material (periphery of the mounting hole 12 of the ceiling material 11) having a predetermined thickness by elastic force. That is, the collar portion 17 and the elastic piece 18 cooperate to function as a holding portion. In the present embodiment, the thickness of the plate material that can be practically sandwiched or pinched by the sandwiching portion (the collar portion 17, the 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 are not limited as long as they are general fixtures or lighting fixtures of the type in which the plate member is sandwiched by the sandwiching portion. 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. Furthermore, the direction of "clamping" is not necessarily limited to the direction perpendicular to the ceiling material 11, and may be of a type in which a clamping pressure is applied such that the clamping portion of the device spreads outward.

  Next, with reference to FIG. 9 to FIG. 11, the fixture installation structure 10 in which the downlight fixture 15 is installed in the attachment hole 12 of the ceiling material 11 using the attachment auxiliary member 100 of the present embodiment will be described. FIG. 9 is a schematic perspective view of the instrument installation structure 10. FIG. 10 is a plan view of the instrument installation structure 10. 11A and 11B are a CC schematic sectional view and a DD schematic sectional view of the instrument installation structure 10. In addition, in the schematic cross-sectional view, for convenience of description, the inside of the instrument body 16 of the downlight instrument 15 is not shown as a cross-section.

  As shown in FIGS. 9 and 10, in the fixture installation structure 10, the fixture body 16 of the downlight fixture 15 is housed in the mounting hole 12 of the ceiling material 11. Further, an annular mounting auxiliary member 100 is placed on the back surface of the ceiling material 11. The downlight fixture 15 is installed on the ceiling material 11 by sandwiching the ceiling material 11 and the mounting auxiliary member 100 by the pair of elastic pieces 18 and the flange portion 17 of the downlight equipment 15.

  More specifically, as shown in FIG. 11A, the upper part of the housing of the instrument body 16 extends toward the rear surface side of the ceiling material 11 with the upper surface of the flange 17 in contact with the 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 periphery of the mounting hole 12 from the rear 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. Then, the attachment auxiliary member 100 is fixed to the peripheral edge of the attachment hole 12 via a double-sided tape (not shown) provided on a part of the contact portion 102. Further, as shown in FIG. 11B, the projecting portion 108 is folded back to the back surface side of the ceiling material 11 and stored in the storage portion 109 so as not to project to the front surface side of the ceiling material 11. The engaging claw 108a of the projecting portion 108 engages with the edge of the notch 109a of the housing portion 109, and the projecting portion 108 is maintained at the housing position. Further, since the housing portion of the instrument body 16 is disposed inside the housed protruding portion 108, the downward rotation of the protruding portion 108 is restricted, and the protruding portion 108 is ex-posted on the surface of the ceiling material 11. It does not hang to the side.

  The elastic piece 18 extends from the upper surface of the flange portion 17 through the mounting hole 12 to the rear surface side of the ceiling material 11. The elastic piece 18 abuts at least the receiving portion 103 of the attachment auxiliary member 100 and is elastically deformed upward (on the rear 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. Then, the elastic restoring force of the elastic piece 18 acts on the receiving portion 103, so that the flange portion 17 and the elastic piece 18 cause the ceiling material 11 (periphery of the mounting hole 12) and the mounting auxiliary member 100 (main body portion 101) to be combined. It is pinched. That is, in the instrument installation structure 10, the thickness of the ceiling member 11 is increased by the thickness of the main body 101, so that the elastic force of the elastic piece 18 is sufficiently exerted. In other words, the elastic deformation of the elastic piece 18 is insufficient only with the thickness of the ceiling material 11, and the ceiling material 11 cannot be firmly sandwiched between the collar portion 17 and the elastic piece 18 without the attachment assisting member 100. As a result, the downlight fixture 15 is stably attached to the attachment hole 12 of the ceiling material 11.

  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 that sandwiches the ceiling material 11 in the thickness direction, is attached to the mounting hole 12. A method of fixing the above will be described.

  First, the mounting auxiliary member 100 is prepared, and as shown in FIG. 12A, the mounting auxiliary member 100 is folded on the front surface side of the ceiling material 11 to be deformed into the second form. Specifically, the pair of split bodies 101a and 101a are relatively rotated about the hinge portion 104 in the direction in which the receiving portion 103 approaches, so that the engaging convex portion 105 and the engaging concave portion 106 are frictionally fitted. The main body 101 is thereby folded. Next, while gripping the projecting portion 107 or the knob portion 112, the mounting auxiliary member 100 deformed into a C shape is inserted through the mounting hole 12 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 attachment assisting member 100 on the back surface of the ceiling material 11. That is, in the case where the double-sided tape is provided in advance on the flat portion 111 on the lower surface of the overhanging portion 107, it is possible to reduce the adhesive force by the operator touching the double-sided tape and making it dirty by utilizing the knob portion 112. It 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 rear surface side of the ceiling material 11 by folding in half in this way. You can Further, since the mounting auxiliary member 100 of the second embodiment is relatively compact, it is easy to handle it on the rear 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 attachment assisting member 100 is expanded from the second form on the back surface side of the ceiling material 11 and then the first auxiliary member 100 is developed. The mounting auxiliary member 100 is arranged on the peripheral edge of the mounting hole 12 by deforming into one form and positioning by the protruding portion 108. Preferably, in a state where the mounting auxiliary member 100 is folded on the back surface side of the ceiling material 11, the mounting auxiliary member 100 is placed on the peripheral edge of the mounting hole 12 while abutting the two protruding portions 108 on the inner peripheral surface of the mounting hole 12, The contact portion 102 of one of the divided bodies 101a1 is brought into contact with the inner peripheral surface of the mounting hole 12. In particular, as shown in FIG. 13B, the outer surfaces of the two protruding portions 108 (which project below the abutting portion 102) are attached while the abutting portion 102 and the peripheral edge of the mounting hole 12 are still separated. By engaging the inner peripheral surface of the hole 12 and bringing the contact portion 102 into close proximity while sliding (or guiding) the peripheral edge of the mounting hole 12, the mounting auxiliary member 100 can be seen without visually observing the mounting auxiliary member 100. Can be easily and quickly positioned. The “engagement” between the outer surface of the protruding portion 108 and the inner peripheral surface of the mounting hole 12 is not limited to the one that does not move against the external force, but it also corresponds to the extent that the position is relatively determined with respect to the mounting hole 12 ( Addressed) is a concept that also includes things.

  Then, one divided body 101a1 is fixed to one side of the peripheral edge of the mounting hole 12 with a double-sided tape, and then the mounting auxiliary member 100 is deformed into the first form while gripping the projecting portion 107, and the other divided body 101a2 is mounted. It is fixed to the other side of the periphery of the hole 12 with a double-sided tape. As a result, the center (or the peripheral edge) of the mounting hole 12 and the through hole 101b can be aligned and the mounting auxiliary member 100 can be easily fixed on the peripheral edge of the mounting hole 12. A magnet (magnetization) may be adopted as the position fixing means instead of the double-sided tape (attachment).

  Subsequently, as shown in FIG. 13B, in a state where the mounting auxiliary member 100 is positioned and fixed, each projecting portion 108 is projected from the first position where it projects from the mounting hole 12 toward the ceiling material 11 front surface side. Is rotated inward and stored in the storage portion 109, whereby the ceiling material 11 is displaced to the second position that does not project to the front surface side. That is, the protruding portion 108 is displaceable such that its protruding length is reduced in a state of being engaged with the inner peripheral surface of the mounting hole 12 (that is, after positioning). At the first position, since the projecting portion 108 penetrates through the mounting hole 12 and projects from the surface of the ceiling material 11, the worker can easily hold the projecting portion 108 from the surface side of the ceiling material 11 and store it. You can In this way, the attachment auxiliary member 100 can be installed on the back surface of the ceiling material 11 to increase the thickness of the periphery of the attachment hole 12.

  Then, as shown in FIG. 14, the downlight fixture 15 (not shown, which is wired to a power source or the like) is inserted from the surface side of the ceiling material 11 toward the attachment hole 12 and the through hole 101b. Specifically, when the upper part of the instrument body 16 is inserted into the attachment hole 12, the elastic piece 18 is elastically deformed upward and inward, so that the instrument body 16 is fixed without contacting the elastic piece 18 with the peripheral edge of the attachment 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 contacts the surface of the ceiling material 11, the elastic piece 18 partially rotates downward and contacts the receiving portion 103. At this time, since the elastic piece 18 is still elastically deformed, the elastic piece 18 biases the receiving portion 103 downward. In this way, by sandwiching the ceiling material 11 and the mounting auxiliary member 100 between the elastic piece 18 and the flange portion 17, the downlight fixture 15 can be installed in the mounting hole 12 of the ceiling material 11.

  The method described here is merely an example, and those skilled in the art can replace the order of the steps or omit or change unnecessary steps depending on the situation. For example, the protruding portion 108 may be cut off instead of being stored in the storage portion 109. In this case, since the thin groove-shaped connecting portion 108b functions as a cutting assist line, the protruding portion 108 can be easily removed.

  Hereinafter, the function and effect of the attachment assisting member 100 according to the embodiment of the present invention will be described.

  According to the attachment assisting member 100 of the present embodiment, the main body portion 101 is clamped together with the ceiling material 11 by the clamping portion of the downlight fixture 15 in the 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 adjusted. That is, the thickness of the main body portion 101 is determined such that the total thickness of the ceiling material 11 and the thickness of the main body portion 101 reaches a thickness that can be held by the holding portion of the downlight fixture 15. Accordingly, the downlight fixture 15 can be attached to the attachment hole 12 of the ceiling material 11 via the attachment auxiliary member 100 regardless of the thickness of the ceiling material 11. Further, the attachment assisting member 100 is characterized in that the protrusion 108 provided on the main body 101 is engaged with the inner peripheral surface of the attachment hole 12 at a position where the abutment portion 102 abuts on the peripheral edge of the attachment hole 12. That is, by engaging the protrusion 108 with the inner peripheral surface of the mounting hole 12, the mounting auxiliary member 100 can be guided to a position where the through hole 101b and the mounting hole 12 communicate with each other and can be positioned quickly and accurately. It is possible. When the ceiling material 11 is thin as in the present embodiment, the protruding portion 108 protrudes to the surface side of the ceiling material 11, but this is not desirable in appearance. On the other hand, the projecting portion 108 is displaceable so as to be housed in the housing portion 109 formed on the inner peripheral surface of the main body 101 so as not to get in the way after performing the function of positioning (guide), or The connecting portion 108b can be cut and removed from the main body 101. Therefore, the attachment auxiliary member 100 of the present embodiment can improve the installation work of the downlight fixture 15 without impairing the appearance of the fixture installation structure 10.

[Modification]
The present invention is not limited to the above embodiment, and various modifications can be adopted. Hereinafter, modified examples of the present invention will be described. In addition, in each of the modified examples, a component whose last two digits are common among components indicated by three digits has the same or similar characteristics unless otherwise described, and the description thereof is partially omitted.

(1) In the attachment assisting member 100 of the above embodiment, the two divided bodies 101a1 and 101a2 can be relatively displaced by the hinge portion 104, but the present invention is not limited to this. For example, the hinge portion may be provided at a position other than the upper wall of the avoiding recess. Further, instead of providing the hinge portion, the two divided bodies may be partially or completely removable. Further, the attachment assisting member of the present invention may be composed of three or more divided bodies. Furthermore, 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 attachment holes. Hereinafter, modified examples of the present invention will be specifically exemplified.

  For example, the attachment assisting member 200 shown in FIG. 15 has a through hole 201b communicating with the attachment hole 22, and has an abutting portion 202 abutting against the peripheral edge of the attachment hole 22 from the rear surface side of the ceiling material 21. The main body portion 201 having a thickness that is sandwiched by the sandwiching portion with the ceiling material 21, and the projecting portion 208 provided on the main body portion 201 so as to project toward the front surface side of the ceiling material 21 with respect to the contact portion 202. Unlike the attachment assisting member 100 of the above-described embodiment, the main body 201 of the attachment assisting member 200 is not a displaceable divided body, but is formed in a C-shape having a notch 210 in a part in the circumferential direction. . Then, as shown in FIG. 15C, the mounting auxiliary member 200 is tilted so that the ceiling member 21 is sandwiched by the notches 210, so that the mounting auxiliary member 200 passes through the mounting hole 22 and the mounting auxiliary member 200 is removed. The ceiling material 21 can be moved from the front surface side to the back surface side. Further, in the attachment assisting member 200, the main body 201 is not provided with a storage portion, and the projecting portion 208 is configured to be cut off by cutting the connecting portion 208b. However, since the main body 201 of the present 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 device spreads outward, a ring shape in which the cutout portion 209 is connected (like the attachment assisting member 100 of the above embodiment) is used. However, the shape of the attachment assisting member is stable, which is preferable.

  For example, the attachment assisting member 300 shown in FIG. 16 has a through hole 301b communicating with the attachment hole, and has an abutment portion 302 abutting against the peripheral edge of the attachment hole from the back surface side of the ceiling material, and a holding portion of the downlight fixture. A main body 301 having a thickness that is sandwiched by the ceiling material, and a protrusion 308 provided on the main body 301 so as to protrude toward the surface of the ceiling material 31 with respect to the contact portion 302. In the main attachment auxiliary member 300, two protrusions 308 are formed on each of the divided bodies 301a1 and 301a2. Unlike the attachment assisting member 100 of the above-described embodiment, the attachment assisting member 300 of the present modification is provided with a flexible deformable bellows-shaped connecting band 310. That is, the pair of divided bodies 301a1 and 301a2 forming the main body portion 301 of the attachment assisting member 300 are tiltably connected to each other by the connecting band 310. That is, by bending, refracting, or retracting the bellows-shaped connecting band 310, the two divided bodies 301a1 and 301a2 can be tilted or brought closer to each other, and can be deformed into a form capable of passing through the mounting hole. Further, in the attachment assisting member 300, the main body 301 is not provided with a storage portion, and the projecting portion 308 is configured to be cut off by cutting the connecting portion 308b.

(2) In the above-described embodiment, the projecting portion can be displaced so as to be folded back through the connecting portion and housed in the housing portion, but the projecting portion of the present invention is not limited to the above-described embodiment. For example, the protrusion may be configured to be slidably moved up and down between the first position and the second position. Further, the shape of the projecting portion is not limited to the above-described embodiment and can be arbitrarily changed as long as it projects toward the ceiling material surface side with respect to the abutting portion and can position the mounting auxiliary member with respect to the mounting hole. For example, the protruding portion may be a rod or a pin that is held in the main body portion so that it can be inserted and removed at a positionable portion.

(3) In the above embodiment, the ceiling material is provided with the circular mounting hole and the downlight device corresponding to the circular mounting hole is installed, but the present invention is not limited to this. For example, the shape of the mounting hole may be other than circular, such as square. In that case, this can be dealt with by changing the outer shape of the mounting auxiliary member according to the shape of the mounting hole. That is, the above embodiment is only one embodiment illustrating the present invention, and within the technical scope of the present invention, depending on the shape and type of the ceiling material or the fixture, the attachment assisting member and the fixture installation structure. The form can be modified appropriately. Further, in the above-described embodiment, the two protruding portions are formed only on one of the divided bodies, but the present invention is not limited to the above-described embodiment. For example, the number of protrusions can be arbitrarily increased or decreased according to the diameter of the mounting hole. Moreover, you may respectively provide a protrusion part in both division bodies.

(4) In the above embodiment, the attachment assisting member is used for the purpose of assisting in attaching the device to the thin ceiling material, but the use is not limited to the embodiment. For example, it may be used for reinforcing the brittle mounting hole periphery of the ceiling material or for changing the diameter of the mounting hole.

  The present invention is not limited to the above-described embodiments and modified examples, and can be implemented in various modes within the technical scope of the present invention.
