Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is intended for mounting a lighting fixture, which is generally called a ceiling light, such as a cord pendant, a pipe pendant, a chain pedant, a spotlight or a floodlight on the ceiling. Regarding the fixture used.

[Conventional technology]

In order to attach the ceiling light as described above to the ceiling, conventionally, a ceiling, a rosette, or the like is used, and a ceiling rosette, a box, or the like is attached by screwing a screw into the ceiling board from the screw insertion holes provided in them, respectively. They used hook ceilings, hook rosettes, or flanges.

[Problems to be solved by the invention]

By the way, recently, ceiling plates have been frequently used in place of wood for plasterboard, asbestos plates, etc. due to various requirements such as disaster prevention and heat insulation, and with the development of new building materials. However, depending on the weight of the equipment, the ceiling plate may be damaged, or the screws may not perform their original functions due to vibration of the ceiling plate or shake of the equipment, sometimes leading to an unexpected situation such as falling of the equipment. .

In addition, prefabricated structures and steel frame structures have become widespread, and there is a tendency for the ceiling not to adopt the means of providing a large number of rims, rims, and rims, unlike the conventional wooden structure. There was a drawback that the mounting position was limited.

On the other hand, especially in recent years, there has been a tendency to request rational and purposeful living spaces, and one of the manifestations is that one flow of architectural style and other The ceiling light fixtures ideally have a diameter similar to that of a sprinkler, since they tend to create a space that emphasizes the aesthetics of the ceiling surface and wall surfaces by not exposing them and making them as invisible as possible. It is desirable to Therefore, the above-mentioned conventional sealing and rosette cannot satisfy this requirement at all.

Therefore, it is needless to say that the present invention solves the drawbacks of the above-described conventional fixtures, and provides a fixture for a ceiling light that eliminates the presence and pressure of other objects on the ceiling and does not impair the aesthetics of the ceiling. With the goal.

[Means for solving problems]

The structure of the present invention for achieving the above object will be described based on the description of FIGS. 1 to 11 corresponding to the embodiment. The present invention has an inner side as a hole 2B for inserting an outlet, and
An annular plate member 2 is integrally provided on the lower edge of the hole, and a tubular fastener 1 having a hole 5 and a locking hole 17 on the upper peripheral wall, and a bent top 6a in the middle are projected outward. The annular plate material 2
At least two mounting springs 6 which are swingably mounted and raised so that the lower end is movable inward and outward through the hole 5, and the locking hole 17 is provided on the upper side. The socket 7 is provided with a locking spring 18 that is detachably locked, and has an outer diameter set to be approximately the same as the inner diameter of the hole 2B for inserting the outlet of the tubular fastener 1. With the outlet 7 inserted into the outlet insertion hole 2B, the upper end portion of the mounting spring 6 is the outlet 7
It is configured to be pressed outward by the peripheral wall.

[Action]

According to the above configuration, in order to attach the fixture to the ceiling plate,
The mounting spring 6 is restricted by the peripheral wall surface of the mounting hole B formed in the ceiling plate, and the upper end side of the mounting spring 6 moves to the center side of the tubular fastener 1 with its lower end as the center, and the entire attachment thereof is tubular. The mounting spring 6 is biased to the peripheral wall side of the tool 1 as much as possible, and is inserted while being biased until it has almost the same diameter as the mounting hole B. After the insertion, the base of the mounting spring 6 is fixed due to the thickness of the ceiling plate. Since it is pressed by the peripheral wall of the mounting hole B, the biased posture is maintained. Next, insert the outlet 7 into the hole 2B for inserting the outlet of the tubular fastener 1 from below, and the outlet 7
The outer peripheral wall of the outlet 7 keeps the upper end of the mounting spring 6 completely fixed when the outlet 7 is pushed out by the outer peripheral wall of the outlet 7 as shown in FIG. Bend top 6b as shown
Keeps the shape of a dogleg protruding outwards and overhangs,
That is, the tubular fastener 1 is not displaced toward the center side. In this state, the ceiling plate is elastically sandwiched between the base side of the mounting spring 6 and the annular plate member 2 so that the weight of the ceiling light acts on the ceiling plate as a downward load from the back side to the front side. The support strength is significantly increased as compared to the conventional structure that employs screws, such as the one that concentrates the load around the screw and applies a local pulling load.

〔Example〕

 Embodiments of the present invention will be described below.

Reference numeral 1 denotes a cover, as shown in FIGS. 1 and 3, a metal cylindrical body (a cylindrical shape in the drawing) having both ends open has a hole 2B for inserting an outlet, and a lower end thereof faces outward, which is an example of an annular plate member. The flange 2 is integrally provided, and the brim 3 is integrally extended downward from the outer peripheral edge of the outward flange 2. Lower end locking holes 4 and 4 of a mounting spring 6 which will be described later are formed at symmetrical positions of the outward flange 2 with respect to the axis of the cylindrical body. The locking holes 4 and 4 have a flat T-shape in the illustrated example, and the hole portion corresponding to the T-shaped arm (short horizontal bar) is provided on the outer edge side of the outward flange 2 and the stem (vertical). A hole portion corresponding to a thick line is provided on the center side of the cylindrical body. Further, in the upper portion of the cylindrical body, in the portions corresponding to the locking holes 4 and 4 of the outward flange 2, square holes 5 and 5 having appropriate dimensions are formed in the axial direction, which are slightly wider than the lateral width of a mounting spring 6 which will be described later. Has been done.

As shown in FIG. 2, the mounting springs 6 and 6 are formed in a dogleg shape by bending a strip-shaped sheet metal at a portion slightly above the center in the longitudinal direction, and the lower end is directed toward the projecting direction side of the folding top 6a. The locking tongue piece 6b bent horizontally is integrally provided, and the upper end side is bent in a protruding direction of the bending top 6a with a rounded shape, and the rounded portion 6c is used as a cam surface. Further, along the bending line of the locking tongue piece 6b, notches 6d and 6d are respectively provided from the left and right sides toward the center, and the width of the remaining connecting portion 6e is smaller than the width of the stem of the locking holes 4 and 4. 〝It is formed short or long.

Reference numeral 7 designates an outer cylindrical outlet, and as shown in FIGS. 4 to 6, the axial length of the cylindrical portion is formed to be slightly longer than that of the cover 1, and the diameter is almost equal to the inner diameter of the cover 1. Has been formed. The outlet 7 has a so-called quick-connect terminal 8 in the center of the upper part thereof, and a lower half has a plug insertion hole 10 in which a pair of left and right plug terminals 9 and 9 are provided. It is connected to the quick-connect terminal 8 via the conductive terminals 11, 11. Further, an outward flange 12 is integrally extended to the peripheral edge of the lower end of the outlet 7, and a groove 12 is formed on the entire upper surface of the outward flange 12 leaving a rib 12a on the peripheral edge.
And the groove 13 has a width that allows the outward flange 2 of the cover 1 to be fitted therein. In the figure, 14 is a lid, 15
Is a release button for the quick-connect terminal 8, and 16 is a locking hole for a claw (not shown) for preventing the plug from coming out, which is formed in the peripheral wall of the plug insertion hole 10.

Reference numerals 17 and 17 are locking holes for preventing the outlet from falling off, which are provided at positions facing each other around the axis near the top of the cover 1,
Reference numeral 8 denotes a locking spring that elastically engages with the locking holes 17 and 17 and is provided on the upper portion of the outlet 7 to cover the outlet 7.
When it is completely inserted into the socket 7, the locking springs 18, 18 are engaged with the locking holes 17, 17 to prevent the outlet 7 from coming out. 19 more
Is a tongue piece for guiding formed by bending a part of the lower peripheral wall of the cover 1 inward, and 20 is a guide groove formed along the axial direction on the outer surface of the outlet for guiding the tongue piece 19. Denoted at 21 are core wire (conductive wire) insertion holes of the cable wiring provided through the lid 14 of the outlet 7.

FIG. 7 is an explanatory view showing the mounting state of the mounting tool, that is, the cover 1, the mounting springs 6 and 6, and the outlet 7.
A circular hole B having a diameter larger than the diameter of the cylindrical portion of the cover 1 and smaller than the diameter of the outward flange 2 is bored at an appropriate position.

The mounting springs 6 and 6 are inserted into the locking holes 4 and 4 of the outward flange 2 with the locking tongues 6b and 6b, and the rounded portion 6c is inserted from the square holes 5 and 5 into the cylinder body. Attach to cover 1. At this time, both corners of the outer sides of the locking tongues 6b, 6b contact the inner peripheral surface of the flange 3 of the outward flange 2, and the connecting portion 6e corresponds to the stem of the T-shaped locking holes 4, 4. Since each part is dimensioned to fit in the hole, the mounting springs 6, 6
Does not fall from the locking holes 4 and 4. Further, the upper rounded portion 6c is also set so as to hold the peripheral wall portion 2f extending from the upper edges of the square holes 5 and 5 to the upper edge of the cylindrical body. In this state, the mounting springs 6 and 6 can be freely displaced both outward and inward.

Cover 1 with mounting springs 6 and 6 set in this way
An outward flange 2 is provided in a circular hole B formed at a proper position on the ceiling plate W.
Is located on the front surface side of the ceiling plate W and is inserted from the upper end, the mounting springs 6 and 6 are largely elastically displaced upward toward the center of the cylindrical body about the locking tongues 6b and 6b, and the circular hole B is formed. Allows plugging in.

Next, the outlet 7 is inserted into the cover 1 from the outward flange 2 side. With the insertion of the outlet 7, the mounting springs 6 are pushed toward the upper end of the outlet and sequentially pushed outward, and finally the peripheral edge rib 12a of the outward flange 12 of the outlet 7 becomes the ceiling plate W. When the contact with the surface is completed and the insertion is completed, the rounded portion 6c of the mounting springs 6 and 6 comes into contact with the outer surface of the outlet 7 and cannot be displaced further inward. And the cover and the outer flange 2 of the outlet 7 are elastically clamped, and the mounting springs 6 are not elastically displaced even if the load of the ceiling light is applied through the plug inserted into the outlet 7. The mounting posture is surely maintained.

Further, when connecting the indoor wiring cable to the outlet 7, the well-known quick-connect type terminal 8 is adopted, but this connecting means is not necessarily required to be adopted, and a widely used screw connecting means may be adopted. Needless to say.

Further, although the plug is inserted into the outlet 7, the electric bulb may be directly screwed into the plug insertion hole 10 of the outlet 7 in this respect as well.

[Effect of device]

As described above, according to the present invention, the mounting spring 6 has its upper end moved to the center side of the tubular fastener 1 about the lower end thereof, and substantially the entire portion thereof is located on the peripheral wall side of the tubular fastener 1. Since it can be inserted into the ceiling mounting hole B while being biased as much as possible and being almost the same diameter as the mounting hole B, the mounting hole B drilled in the ceiling plate is substantially the same as the net tubular fastener 1. The same diameter, so to speak, a small diameter that is almost the same as the outer dimensions of the outlet 7 can be made, and the opening that occurs in the ceiling can be made extremely small. I was able to create a favorable space with little presence and pressure of other things by maintaining this without losing its aesthetics. Also, the insertion of the attachment into the attachment hole B of the ceiling can be carried out easily and easily with little risk of damaging the peripheral wall of the attachment hole.

Since the mounting tool is mounted in such a manner that the mounting plate 6 and the annular plate member 2 elastically sandwich the ceiling plate from both the front and back surfaces thereof, the ceiling plate portion around the screw as in the conventional screw is adopted. It is possible to significantly increase the support strength without the risk of concentrating locally on the lowering load, and there is no drawback that the mounting strength is weakened by the vibration of the ceiling plate or the shaking of the equipment, etc., and safe mounting is possible.

Further, since it can be attached only by forming a hole at a desired position on the ceiling plate, there is no restriction on the attaching position and the attaching operation is extremely easy.
