[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting fixture for use in attaching a lighting fixture to a shaft member fixed to a fixing portion.

[0002]

2. Description of the Related Art FIG. 5 shows a conventional fixture for lighting equipment, in which an engaging member 03 having a cutout portion 02 which is inserted radially into each of shaft members 01 fixed at two places on a ceiling wall. Is attached to the lower surface of the top plate 04 of the lighting fixture so as to swing freely between an engagement position where the notch portion 02 enters the shaft member 01 and a disengagement position where the notch portion 02 comes off the shaft member 01. A shaft member 01 to which a washer 06 is attached in advance is inserted into each of the two formed through holes 05 from the upper surface side.
From the shaft member 01 in the axial direction is prevented by contact with the washer 06 at the lower end of the shaft member 01, and the lighting fixture is moved to the shaft member 0.
It is suspended and fixed to 1.

[0003]

According to the above prior art, since the engaging member 03 is engaged with the shaft member 01 only in one direction, the engaging member 03 is caused by vibration or shaking. 0
3 is gradually rubbing against the lighting device, or while the lighting device itself is gradually rubbing against the shaft member 01, the engagement between the engaging member 03 and the shaft member 01 is released, The lighting equipment may fall. In order to solve this drawback, a mounting board with a through-hole through which a bolt is inserted is fixed to the lighting fixture side, the bolt fixed to the ceiling wall is inserted through this mounting board, and then inserted into the insertion end. It is only necessary to screw the nut and securely fix the lighting fixture in a state where the mounting board does not come off from the bolt. In this case,
There is a disadvantage that the installation work is troublesome. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a fixture for a lighting fixture capable of securely attaching the lighting fixture for a long time by a simple attaching operation.

[0004]

The features of the present invention for achieving the above object are as follows. An engaging portion for preventing the shaft member fixed to the fixing portion from coming off in the axial direction from the shaft member by radial engagement with the shaft member; and a supporting portion for placing and supporting the lighting fixture. B. a fixture for the lighting fixture. A pair of engagement members engaged in a state where the engagement portion is fitted into the shaft member from the radial direction thereof so as to be relatively swingably connected between an engagement position and an engagement release position. C. A fixture for a lighting fixture provided with a swing regulating part for regulating a swinging movement of the engaging member from an engagement position by engagement with the lighting fixture side in a state of being placed and supported on the support part.
The above A, B. C. Further, the pair of engagement members may be urged to swing toward the engagement position.

[0005]

According to the structure of the above A, the fixture is prevented from coming off by radial engagement with the shaft member, and the lighting fixture can be placed and supported on the fixture. According to the configuration of B, the pair of engaging members are engaged with the shaft member in two states in a state of being fitted into the shaft member and are prevented from coming off, so that even if the lighting fixture itself gradually rubs against the shaft member, The engagement between the engaging portion and the shaft member is not easily released. With the configuration C, the engaging member can be held at the engaging position, so that the engaging member is less likely to rub against the lighting fixture, and the lighting fixture is placed and supported on the supporting portion. Such a rubbing movement can be easily regulated. When the pair of engagement members are urged to swing toward the engagement position, the engagement is unlikely to be disengaged even when only the attachment is engaged with the shaft member alone.

[0006]

Therefore, the lighting equipment can be securely mounted for a long time by a simple mounting work. In the lighting fixture according to the second aspect, the fitting is less likely to be detached from the shaft member during the mounting operation, and can be efficiently mounted.

[0007]

FIG. 1 shows a lighting device 2 of a ceiling embedded type mounted on a shaft member 1 in which a washer 13 and a nut 14 are previously mounted on a bolt 8 fixed downward to a ceiling wall A as an example of a fixing portion. FIG. 3 shows a mounting member 3 for mounting, and is engaged with the shaft member 1 from a radial direction so that the shaft member 1 can be mounted.
A pair of sheet metal engaging members that engage with the engaging member 4, which is prevented from coming out of the shaft member in the axial direction by contact with the washer 13, is fitted into the shaft member 1 from its radial direction. 5
And a torsion coil spring configured to be relatively swingably connected around the swing shaft 6 between the engagement position and the disengagement position, and to urge the engagement members 5 to swing toward the engagement position. 7 is mounted. Each of the engaging members 5 is formed with a notch 9 into which the bolt 8 of the shaft member 1 enters radially, and a guide surface 21 is formed so that the shaft member 1 can easily enter the notch 9. A support plate 10 which constitutes a support portion for mounting and supporting the top 15 side of the lighting fixture 2, and a slit formed on the top plate 15 side with the lighting fixture 2 placed and supported on the support plate 10. Into an elongated hole 12, and an engaging piece 11 as a swing regulating portion for regulating the swing movement of the engaging member 5 from the engagement position by engagement with the elongated hole 12 is integrally formed, A tongue piece 22 for regulating the relative swing range of the engaging members 5 is formed by bending toward one of the engaging members 5.

FIG. 3 and FIG. 4 show a method of attaching the lighting fixture 2 to the shaft member 1 with the above-mentioned fixture 3, and as shown in FIG. The fixture 3 is held by each of the shaft members 1 in a state where the fixture 3 is held in contact with the washer 13 and the fluorescent lamp 16 is removed from the socket 17 in a state where the fluorescent lamp 16 is removed from the socket 17. After the support plate 10 portion of the mounting tool 3 is inserted through the rectangular through hole 18 formed in 15, the mounting tool 3 is rotated 90 degrees around the shaft member 1, as shown in FIG. When the top plate 15 is placed on the support plate 10 while inserting the engagement pieces 11 into the elongated holes 12 on the lighting fixture 2 side, the lighting fixture 2 is temporarily fixed to the shaft member 1 via the fixture 3. It is placed and supported. Then, as shown in FIG. 2, the nut 14 is tightened, and the flange 19 provided on the lower end edge of the lighting fixture 2 is applied to the ceiling plate 20, so that the lighting fixture 2 becomes the shaft member 1.
Is fixed in a predetermined posture.

[Other Embodiments] The shaft member that engages the pair of engaging members may not include the bolt and nut as long as the shaft member can be prevented from coming off in the axial direction by the engagement by the engaging member. 2. The pair of engaging members that engage with the shaft member in a state of being fitted in the radial direction are engaged with the shaft member, and the swinging movement from the engagement position is regulated. ,
The engagement member and the shaft member may be provided with flexibility that allows relative movement in the shaft member radial direction. 3. The pair of engaging members that engage with the shaft member in a state of being fitted in the radial direction are engaged with the shaft member, and the swinging movement from the engagement position is regulated. ,
The shaft member may be sandwiched from the radial direction. 4. The swing restricting portion that restricts the swinging movement of the engaging member from the engagement position by engaging with the lighting fixture side mounted and supported on the support portion fits into the uneven surface formed on the lighting fixture side. Thus, the swinging movement of the engagement member from the engagement position may be restricted.
