Description

  The present invention relates to a lighting fixture mounting jig, and more particularly to a lighting fixture mounting jig for mounting a ceiling-embedded lighting fixture in a state of being embedded in an opening formed in a ceiling board.

  When lighting with a lighting fixture attached to the ceiling, if a large number of lighting fixtures are suspended from the ceiling, the ceiling may become cluttered and the indoor landscape may be damaged. When mounting, a so-called “ceiling-embedded” lighting fixture is often used in which the lighting fixture is embedded in a mounting opening provided on the ceiling.

  As an example of such a ceiling-embedded lighting fixture, a case where a ceiling-embedded downlight is attached will be described with reference to FIGS. 8A and 8B. When attaching the downlight main body 170, first, an attachment jig for attaching the downlight main body 170 to the attachment opening 151 provided in the ceiling board 150 is attached.

  In the example shown in FIGS. 8A and 8B, an annular frame 110 is provided as such a mounting jig.

  In the illustrated example, the annular frame 110 has an outer diameter that can be fitted into an attachment port 151 formed in the ceiling board 150, and is formed in a size that allows the downlight body 170 to be fitted to the inner diameter. A substantially cylindrical main body portion 112 and a flange 111 projecting outward from the lower end edge of the main body portion. The main body portion 112 of the frame 110 is inserted into an attachment port 151 provided in the ceiling board 150 from the indoor side. In the state where the flange 111 is inserted and brought into contact with the peripheral edge of the mounting port 151, the mounting bracket 124 provided on the mounting mechanisms 113 and 114 is lowered and provided on the mounting bracket 124 as shown in FIG. The outer plate 131 is protruded in the outer peripheral direction of the frame body 110 and locked to the back surface of the ceiling board 150, so that the ceiling board 150 is sandwiched between the outer plate 131 and the flange 111 and the frame body 11. There is secured in the mounting hole 151 formed in the ceiling board 150.

  Then, by attaching the components of the downlight main body 170 to the frame 110 attached to the attachment port 151 in this way, the downlight is attached in an embedded state in the attachment port 151 provided on the ceiling board 150. (Patent Document 1).

  Further, as another method of mounting the lighting fixture in the mounting state 151 formed in the ceiling board 150, as shown in FIG. 9, the bottom opening of the fixture mounting frame 140 having a box shape opened downward is used as shown in FIG. It is arranged on the back of the ceiling toward the mounting port 151 formed on the board 150, and a lighting fixture is also mounted in the fixture mounting frame 140. The mounting port 151 provided with the fixture mounting frame 140 on the ceiling is also used. In order to fix in the inside, the fixing piece 120 formed by punching metal or the like protrudes horizontally from the side surface of the instrument mounting frame 140, and a screw is driven toward the fixing piece 120 from an appropriate position on the indoor side, Screws are inserted into any of the small holes 125 formed in the fixed piece 120 and screwed together, so that complicated operations such as positioning of screw driving positions are performed. Without, it has also been proposed to be able to carry out the fixing of the device mounting frame 140 (Patent Document 2).

Japanese Patent Laying-Open No. 2005-346957 (FIGS. 1 and 2) JP 2007-188720 A (FIGS. 1 and 2)

  Among the conventional technologies described above, in the downlight introduced as Patent Document 1, the above-described frame body 110 formed in an annular shape is attached to attach the downlight main body 170 to the attachment port 151 provided in the ceiling board 150. It functions as a jig, and it is convenient in that the downlight main body 170 can be attached to and detached from the mounting hole 151 relatively easily by attaching the frame body 110 to the mounting port 151 formed on the ceiling in advance.

  However, the reason why the lighting fixture attached to the ceiling is embedded in the ceiling is to hide the presence of the lighting fixture provided on the ceiling when observing from the room as described above. The existence of lighting fixtures that can be observed is required to be as inconspicuous as possible when observed from the indoor side.

  However, when the downlight is mounted using the above-described annular frame 110 described in Patent Document 1, the above-described annular frame formed of a material different from the material of the ceiling or the like. Since the outer periphery of the mounting port 151 that accommodates the downlight is framed by 110, the mounting port 151 and by extension the presence of the downlight is emphasized.

  In addition, since the annular frame 110 includes the flange 111 that holds the ceiling board 150 between the outer plate 131 of the mounting bracket 124 as described above, the annular frame 110 is provided between the ceiling board 150 and the frame 110. Has a step corresponding to the thickness of the flange 111.

  The presence of such a step makes it impossible to perform cross-sticking on the frame 110 integrally with the ceiling board 150, for example, when the ceiling is finished by cross-sticking.

  In addition, when the ceiling is finished by painting, even if the frame 110 can be made inconspicuous to some extent by painting the frame 110 in the same color as the ceiling, the existence of the above-described step itself can be avoided. It cannot be erased.

  As a result, the presence of such a frame 110 causes poor appearance when the ceiling is viewed from the indoor side, and particularly when a plurality of downlights are arranged adjacent to each other, the frame 110 enters the field of view. This emphasizes the presence of downlights on the ceiling.

  On the other hand, as introduced in Patent Document 2, when a box-shaped fixture mounting frame 140 for housing a lighting fixture is attached to the ceiling, if the fixture mounting frame 140 does not have a flange, the ceiling board 150 is attached. The opening edge of the provided attachment port 151 is not trimmed.

  However, in the annular frame 110 described in Patent Document 1 described above, the inner diameter of the frame 110 is filled by the downlight main body 170, so that the attachment port 151 formed in the ceiling board 150 is not attached to the frame 110. However, the fixture mounting frame 140 introduced as Patent Document 2 is a comparative example formed on the ceiling even after the lighting fixture is mounted in the fixture mounting frame 140. The large attachment port 151 (the lower end opening of the instrument attachment frame 140) remains without being blocked.

  As a result, when observed from the indoor side, the attachment port 151 (the lower end opening of the device mounting frame 140) existing on the ceiling enters the field of view, and the presence of the lighting device can be clearly recognized.

  Accordingly, the present invention has been made to solve the above-described drawbacks of the prior art, and it is possible to attach a ceiling-embedded lighting fixture to the ceiling in an inconspicuous state as much as possible, and to attach to the ceiling. An object of the present invention is to provide a mounting jig for a ceiling-embedded lighting fixture that can be easily operated.

In order to achieve the above object, a mounting fixture 1 for a lighting fixture according to the present invention includes a rectangular bottom plate 11 having an opening 11a into which the lighting fixture is fitted, and side plates erected from four sides of the bottom plate 11, respectively. A jig body 10 having 12 to 15 and having a substantially box shape as a whole;
A jig fixing piece 21 attached to the outer periphery of the jig main body 10 and a ceiling board fixing piece 22 protruding in a direction orthogonal to the jig fixing piece 21 from the lower end of the jig fixing piece 21. A pair of fixtures 20, 20 having an L-shape are provided,
A plurality of small holes 25 serving as screw holes are formed in at least the ceiling board fixing piece 22 of each of the fixtures 20, 20, and the upper end of the jig fixing piece 21 is preferably parallel to the ceiling board fixing piece 22. In addition, a positioning piece 24 protruding in the opposite direction to the ceiling board fixing piece 22 is provided,
An attachment portion 16 for attaching the jig fixing piece 21 of the fixture 20 to the pair of side plates 12 and 13 facing each other among the side plates 12 to 15 of the jig body 10 is provided. A plurality of fitting grooves 18a to 18c into which the positioning pieces 24 can be fitted are provided, preferably in parallel with the bottom surface of the bottom plate 11, respectively.
Fixing means for fixing the jig fixing piece 21 of the fixing tool 20 to the mounting portion 16 in a state where the positioning piece 24 is fitted in any one of the fitting grooves 18a to 18c is provided. The arrangement height of the ceiling board fixing piece 22 relative to the bottom surface of the bottom plate 11 of the tool body 10 is variable (Claim 1).

  In the mounting jig 1 having the above-described configuration, the upper end edge 16a that is parallel to the fitting grooves 18a to 18c is formed in the mounting portion 16, and the bottom surface of the positioning piece 24 is placed on the upper end 16a. The jig fixing piece 21 of the fixture 20 can be configured to be fixable to the mounting portion 16 (Claim 2).

  In addition, the jig mounting piece 21 is fixed by forming a long hole 23 having a height direction in the jig fixing piece 21 and a screw 62 inserted into the long hole 23; This can be done by forming the fixing means by a screw hole 17 provided in the mounting portion 16 screwed into the screw 62 (Claim 3).

  Further, among the side plates 12 to 15 of the jig body 10, the outer walls of the pair of side plates 14 and 15 other than the pair of side plates 12 and 13 to which the fixture 20 is attached are upward from the bottom plate 11 side. The two inclined surfaces are divided and formed by one inclined surfaces 14a and 15a which are gradually inclined outward and the other inclined surfaces 14b and 15b which are gradually inclined inward from the bottom plate 11 side. In addition, the other pair of side plates 14 and 15 may be formed in the same shape (claim 4).

In this case, a through hole 32 having the same shape may be provided at a common position of each of the other pair of side plates 14 and 15 (Claim 5).
Further, each of the other pair of side plates 14 and 15 protrudes to the outer peripheral side of the jig body 10 from the upper end edges 14e and 15e of the one inclined surface 14a or 15a or the other inclined surface 14b or 15b. The tongue piece 19 is provided, and the bottom surface of the tongue piece 19 is locked to the upper end edges 14 f and 15 f of the inclined surfaces not forming the other tongue pieces 19. (Claim 6).

  A rib 11b can be preferably formed on the upper surface of the bottom plate 11 of the jig body 10 (claim 7).

  With the configuration of the present invention described above, the jig body 10 is fitted into the mounting opening 51 by inserting the jig body 10 from the bottom of the ceiling 11 into the mounting opening 51 formed in the ceiling board 50. At the same time, the ceiling board fixing piece 22 of the fixture 20 is locked to the opening edge to prevent the jig from dropping, and a screw is driven in from the indoor side. By screwing into the hole 25, the jig body 10 could be fixed in the mounting opening 51 without providing a flange at the lower edge of the jig body 10.

  Further, by adjusting the position of the ceiling board fixing piece 22 of the fixture 20, the distance s between the bottom surface of the bottom plate 11 of the jig body 10 and the bottom surface of the ceiling board fixing piece 22 of the fixture 20 is made to correspond to the thickness of the ceiling board 50. As a result, the bottom surface of the bottom plate 11 of the jig main body 10 can be arranged close to the same plane or the same plane as the surface of the ceiling board 50 on the indoor side.

  As a result, in the mounting jig 1 of the present invention, the occurrence of a step between the ceiling board 50 and the jig body 10 on the indoor side can be eliminated. For example, the opening edge of the mounting port 51 formed in the ceiling board 50, By simply filling the gap between the jig body 10 and the head of the screw 60 driven into the ceiling board 50 from the indoor side with a sealing material, a common cloth is used between the ceiling and the bottom of the fixture. The attachment jig 1 can be constructed in such a way that its presence cannot be determined by applying a series of stickers or by painting the jig integrally when painting the ceiling.

  In addition, since the ceiling board fixing piece 22 of the fixture 20 is configured to have a large number of small holes 25 serving as screw holes, the screws 60 are appropriately driven from the indoor side toward the ceiling board fixing piece 22 on the back of the ceiling. It was possible to attach it easily without performing complicated operations such as positioning the screw holes.

  An upper end edge 16a that is parallel to the fitting grooves 18a to 18c is formed in the mounting portion 16, and the jig of the fixture 20 is mounted with the bottom surface of the positioning piece 24 placed on the upper end edge 16a. In the configuration in which the fixing piece 21 can be fixed to the mounting portion 16, the fitting groove can be replaced by the upper end edge 16 a of the mounting portion 16, thereby reducing the number of fitting grooves formed. As a result, the jig main body 10 can be easily manufactured.

  In addition, a long hole 23 whose length direction is the height direction is formed in the jig fixing piece 21, a screw 62 inserted into the long hole 23, and a mounting portion 16 screwed into the screw 62. With the configuration provided with the provided screw hole 17, it is possible to form a fixing means for making the mounting position of the jig fixing piece 21 variable with a relatively simple configuration.

  Out of the side plates 12 to 15 of the jig body 10, the outer walls of the pair of side plates 14 and 15 other than the pair of side plates 12 and 13 to which the fixture is attached are connected to the inclined surfaces 14 a, 14 b and 15 a described above. 15b, when the plurality of mounting jigs 1 are continuously mounted, the side plate 14 of one jig main body and the side plate 15 of the other jig main body 10 are arranged to face each other. Thus, it is possible to easily align the centers of the mounting jigs 1 and 1 and to prevent the positional deviation between the jig bodies 10 and 10.

  In this case, the through hole 32 having the same shape is provided at the symmetrical position of each of the other pair of side plates 14 and 15 having the inclined surface. It is possible to easily connect the two jig main bodies 10 by inserting bolts or the like, and connect the two jig main bodies 10 by screwing nuts into the bolts inserted into the through holes 32. Then, the jig bodies 10 were firmly connected by the contact between the inclined surfaces 14a, 15a, 14b, and 15b described above, and the jig bodies 10 could be connected in a state in which the positional deviation hardly occurred.

  Further, in the configuration in which the tongue piece 19 is provided at the upper end on one side of the inclined surface, the height adjustment between the jig bodies 10 connected by the tongue piece 19 is facilitated, and the connected jig body 10 It was also possible to prevent a height shift from occurring between the bottom surfaces of the bottom plate 11.

  In the configuration in which the rib 11b is provided on the upper surface of the bottom plate 11 of the jig body 10, it is possible to prevent shrinkage due to sink marks at the time of manufacture, and the size of the jig body 10 varies due to the shrinkage difference. In particular, when a plurality of mounting jigs 1 are connected and used, it is possible to prevent gaps and deviations from occurring between the jig main bodies 10.

  Next, the lighting fixture mounting jig 1 of the present invention will be described with reference to the accompanying drawings.

[Structure of mounting jig]
As shown in FIG. 4, the mounting fixture 1 for a lighting fixture according to the present invention is fitted in the mounting opening 51 and the jig body 10 that is fitted in the mounting opening 51 formed in the ceiling board 50. The jig body 10 is composed of a pair of fixtures 20 and 20 for fixing the jig body 10 to the ceiling board 50.

  The jig body 10 includes a rectangular bottom plate 11 and four side plates 12 to 15 that rise upward from the four sides of the bottom plate 11 as shown in FIGS. An opening 11 a for attaching a lighting fixture is formed in the bottom plate 11 of the jig body 10.

  The opening 11a has a shape corresponding to the shape of the lower end edge of the lighting fixture attached to the attachment jig 1, and is provided in the downlight when the lighting fixture attached in the opening is, for example, a downlight. If the downlight has a substantially cylindrical cone extending forward from the reflector opening, the outer periphery of the opening of the cone is fitted and the opening 11a is comprised so that it may be block | closed by the lower end edge of a lighting fixture.

  A plate spring-like mounting bracket 34 protruding into the opening 11a is provided at the periphery of the mounting opening. When the lighting fixture is inserted into the opening 11a, the mounting fixture 34 is pressed against the outer periphery of the lighting fixture. , It is comprised so that a lighting fixture can be latched in the opening 11a.

  A rib 11b formed by partially increasing the thickness of the bottom plate 11 is provided on the upper surface of the bottom plate 11 of the jig body 10 as shown in FIG. 1A. The strength of the tool body 10 is improved, and the occurrence of sink marks (cooling shrinkage) at the time of molding is prevented, so that the size error and the like generated at the time of manufacturing the obtained jig body 10 is minimized. It is configured.

  In the illustrated embodiment, the ribs 11b are provided in a grid pattern. However, the arrangement of the ribs 11b is not limited to the example shown in the figure. The configuration is not particularly limited as long as it can prevent the above.

  As shown in FIG. 3, the fixture 20 has a shape similar to an angle member having a substantially L shape in a cross section perpendicular to the length direction of the fixture 20, and two pieces constituting the L shape. One of the two side plates 21 and 22 constitutes a jig fixing piece 21 attached to the outer wall side of the pair of side plates 12 and 13, and the other piece protruding in the orthogonal direction from the lower end of the jig fixing piece 21 The ceiling board fixing piece 22 is fixed to the ceiling board 50 so that the ceiling board fixing piece 22 is parallel to the bottom surface of the bottom plate 11 of the jig body 10 and protrudes to the outer peripheral side of the jig body 10. The jig fixing piece 21 is used by being attached to the side plates 12 and 13 on the outer peripheral side of the jig main body 10.

  Accordingly, in this state, when the jig body 10 is inserted into the mounting opening 51 of the ceiling board 50 formed slightly larger than the bottom shape of the jig body 10 with the bottom plate 11 side downward from the ceiling back side, the ceiling board is fixed. The piece 22 is placed on the ceiling board 50 on the back side of the ceiling so that the mounting jig 1 does not fall out to the indoor side (see FIG. 4).

  As shown in FIGS. 1 (B) and 6 (B), the jig fixing piece 21 of the fixture 20 is provided with a long hole 23 whose length direction is the height direction.

  In the illustrated embodiment, only one of the long holes 23 is provided at the center position in the length direction of the jig fixing piece 21, but this long hole 23 is formed at the jig body 10 side. This is determined by the relative relationship between the formation position and the number of formed screw holes 17 and is not limited to the illustrated embodiment.

  As shown in FIGS. 3 to 5, a positioning piece 24 is provided at the upper end of the jig solid piece 21 so as to project in the direction opposite to the ceiling board fixing piece 22 (on the jig body 10 side).

  In the illustrated embodiment, the positioning piece 24 is provided over the entire length of one side forming the upper end of the jig fixing piece 21, but the formation range of the positioning piece 24 is not necessarily limited to that of the jig fixing piece 21. It is not necessary to provide it over the entire length, and it may be provided corresponding to the formation range (formation length of the fitting grooves 18a to 18c) of a mounting portion 16 described later provided in the jig body 10.

  A plurality of small holes, which are screw holes into which screws 60 driven into the ceiling board 50 from the indoor side toward the ceiling board fixing piece 22 are screwed into at least the above-described ceiling board fixing piece 22 of the fixture 20. 25 is formed (see FIGS. 1A and 1D).

  The small hole 25 has a diameter smaller than the diameter of the screw 60 to be used. When the tip of the screw 60 protruding through the ceiling board 50 and projecting to the back of the ceiling is inserted into the small hole 25, the small hole 25 is rotated. The screw 60 is screwed while expanding and deforming the small hole 25. Since a large number of small holes 25 serving as screw holes are formed as described above, the small hole 25 can be moved from an appropriate position inside the room. , Just by driving the screw 60 toward the ceiling board fixing piece 22, the screw can be fastened without aligning with the small hole 25.

  Such a small hole 25 can be easily provided by forming a fixture 20 by bending a punching metal made of a relatively soft metal such as an aluminum material into an L shape. The hole 25 is formed not only on the ceiling board fixing piece 22 described above, but also on the entire fixture 20 including the jig mounting piece 21 and the positioning piece 24.

  However, since such a small hole 25 is provided for screwing the screw 60 to the ceiling board fixing piece 22, it should be provided at least for the ceiling board fixing piece 22. good.
