Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an embedded lighting fixture, and more particularly to mounting a so-called downlight.

[Prior Art] Conventionally, in a downlight, which is a type of embedded lighting fixture,
In particular, a small downlight as shown in FIG. 5 is well known. In this embedded lighting fixture, a fixture body 1'equipped with a socket 5'for mounting a lamp 6 '.
Is a leaf spring that is inserted into an embedding hole 15 formed in the ceiling 14 and has its lower end attached to the frame 2'of the frame 2'of the instrument body 1'and its upper end widens outward in the free state. The ceiling 14 is sandwiched and mounted by the mounting spring 9 '.

The operation of the mounting spring 9'during the mounting operation and in the mounted state will be described below. When the instrument body 1'is inserted into the embedding hole 15 of the ceiling 14, the mounting spring 9'is pressed to the side of the instrument body 1'in a substantially close contact state. Then, the instrument body 1'is pushed all the way in, so that the frame 2'of the instrument body 1'is ceiling 14
When it comes into contact with the mounting spring 9 ', the upper end of the mounting spring 9'will come into contact with the upper end edge of the embedding hole 15 in an attempt to spread outward, and the instrument body 1'will be pulled upward by the elastic return force to the free state.
The frame 2'is pressed against the ceiling 14.

[Problems to be solved by the device]

In such an embedded lighting fixture, as described above, the fixture main body 1'is attached to the ceiling 14 by the elastic restoring force of the attachment spring 9'to the free state. However, as the ceiling 14 becomes thicker, the mounting spring 9'with the instrument body 1'attached gradually approaches a state parallel to the instrument body 1 '. Along with this, the direction of the force applied from the mounting spring 9'to the ceiling 14 also changes from the vertical direction to the horizontal direction, and the force for holding the instrument body 1'is from the elastic restoring force of the mounting spring 9 'itself. Instead of the frictional force due to the elastic restoring force of ′,
Holding power becomes smaller. Therefore, there is a problem that the instrument body 1'is likely to be displaced due to its own weight.

Therefore, in order to solve the above problem, it is necessary to make the diameter of the embedding hole 15 larger than the diameter of the instrument body 1 ', so that the mounting spring 9'returns until it comes close to the free state. Along with this, the width of the frame 2'provided at the lower end of the instrument body 1'and covering the embedding hole 15 becomes wider, and the frame 2 '
May be too conspicuous.

The present invention has been made in view of the above background, and an object of the present invention is to provide an embedded lighting fixture in which the main body of the fixture can be securely attached to the embedded hole in the ceiling without widening the frame width. To provide.

[Means for Solving the Problems]

In the embedded lighting fixture according to the present invention, a plurality of mounting springs are arranged on the side surface of the main body of the fixture which is equipped with a socket for mounting the lamp, and the main body of the fixture is embedded in an embedded hole formed in the ceiling. In the embedded luminaire, which is pressed against and is pulled up by the elastic return force to bring the fixture body into contact with the outer collar at the lower end of the fixture body to affix it to the mounting surface, a generally rectangular mounting spring is fixed to the side face of the device body. At the same time, the upper end of the device is attached to the side surface of the main body of the device while preventing its movement inward and outward and upward, and is projected outward in a substantially arc shape.

〔Example〕

1 to 4 show an embodiment of the present invention, which will be described below with reference to the drawings.

The instrument main body 1 is formed by integrally assembling a frame 2 having a substantially cylindrical shape and an outer flange at the lower end and a substantially flat dish-shaped top plate 3 by a pair of rectangular plate-shaped body side surfaces 4. . Further, the pair of main body side plates 4 are fixed to the frame 2 and the top plate 3 with rivets or the like at the lower end and the upper end to the frame 2 at both ends of one diameter, respectively.

The socket 5 is integrally assembled with the reflector 7 that covers the lamp 6 mounted on the socket 5 so as to form a block so that the lamp 6 maintains a predetermined position of the reflector 7. A pair of reflecting plate mounting springs 8 are arranged at a position of the frame 2 which is displaced by approximately 90 degrees from the mounting position of the main body side plate 4, and the reflecting plate mounting springs 8 push up the blocking reflecting plate 7 to cause reflection. The outer flange at the lower end of the plate 7 is attached to the lower surface of the frame 2 so as to abut.

Mounting springs 9 which are formed in a substantially rectangular shape by a stainless steel thin plate or the like for mounting the device main body 1 are mounted on the main body side plates 4 at both ends thereof and project outward in an arc shape. The main body side plate 4 is provided with a notch-shaped mounting portion 10 that is slightly wider than the mounting spring 9 at the lower end, and a substantially inverted T-shaped locking portion 11 that is slightly wider than the mounting spring 9 in the wide portion near the upper end. There is. On the other hand, in the mounting spring 9, a fixing portion 12 folded back in a hook shape at the lower end is formed in a substantially T shape at the upper end, and the narrow portion is slightly narrower than the narrow portion of the locking portion 11 of the main body side plate 4. Engaging portions 13 are formed respectively. Fixed part 12 of mounting spring 9
Is inserted into the mounting portion 10 of the body side plate 4 and is clamped and fixed near the hook-shaped tip between the frame 2 and the body side plate 4. Further, the engaging portion 13 of the mounting spring 9 is inserted into the engaging portion 11 of the body side plate 4 from the wide portion of the engaging portion 11, and the narrow portion of the engaging portion 11 is provided with the narrow portion of the engaging portion 13. It is inserted and prevented from moving inside and outside and upward.

The mounting spring 9 is attached to the main body side plate 4 so as to be stretched between the mounting portion 10 and the locking portion 11 of the main body side plate 4 by the elasticity of the mounting spring 9 itself.

This embedded luminaire has a ceiling as shown in FIG.
It is attached to an embedding hole 15 formed in 14. First, as shown in FIG. 3 (a), the instrument body 1 is inserted from the top plate 3 into the embedding hole 15 formed in the ceiling 14 having a diameter slightly larger than the top plate 3 and the frame 2 of the instrument body 1. Go. Then, the mounting spring 9 has an embedded hole.
When it is inserted into the mounting spring 9, the mounting spring 9 begins to elastically deform so that only the portion outside the ceiling 14 projects outward, and during the mounting of the instrument body 1, as shown in FIG. 14 It projects outward on both the upper and lower sides. When the mounting is completed, as shown in FIG. 3C, the vicinity of the lower end of the mounting spring 9 is substantially in close contact with the side surface of the embedding hole 15, and the exposed portion of the mounting spring 9 above the ceiling is arcuately outward. And the attachment spring 9 has an arcuate inclination to prevent the instrument body 1 from slipping.

In this embedded luminaire, when the ceiling 14 is thick, as shown in FIG. 3, and when the ceiling 14 is thin, as shown in FIG. It projects outward in an arc shape and is locked to the upper edge of the embedding hole 15 of the ceiling 14,
The mounting spring 9 is always locked on the upper surface of the ceiling 14 so that the mounting spring 9 is not mounted only by the frictional force, and the fixture body 1 is securely mounted in the embedding hole 15 of the ceiling 14. You can

Therefore, in this embedded lighting fixture, the fixture body 1 and the embedded hole are
The frame 2 of the device body 1 can be made small without increasing the gap with the device 15 so that the appearance can be improved.

Further, since the upper end of the mounting spring 9 is mounted on the main body side plate 4, it is not necessary to press the mounting spring 9 when inserting the instrument main body 1 into the embedding hole 15, and the mounting work can be simplified.

The upper and lower ends of the attachment spring 9 may be attached to the main body side plate 4, and the attachment method may be another method such as a screw. Further, the mounting springs 9 may be provided in the required number depending on the size and weight of the instrument body 1. Further, the instrument main body 1 may be a cylindrical one, a rectangular tubular one, or the like.

[Effect of device]
