Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the structure for attaching a socket base to a main body of a lighting device.

Conventionally, in a two-lamp fluorescent lighting fixture, as shown in FIG. 1, both ends of a socket mounting piece 1 formed by providing a socket mounting part 2 and a reflector mounting part 3 are folded inward and attached to each other. A socket base 5 having a substantially inverted triangular shape is provided by forming horizontal mounting pieces 4, 4 facing each other, and the mounting piece 4.4 is mounted on the end of the instrument body 6 by screws etc. 4 is fixed to the instrument body 6.

The reflector plate 7 is provided with a socket through hole 8 as shown in FIG. is inserted into the socket through hole 8 and fixed to the reflector mounting portion 3 with decorative screws 10.

Reference numeral 11 denotes a pot screw for a decorative screw 10 provided on the reflector mounting portion 3.

By the way, as mentioned above, the socket stand 5 has a structure made by bending a thin steel plate, and its overall rigidity is low.In the conventional type, it is weak against the force in the direction A in the figure, so when the reflector plate 7 is attached, it may fall down. A gap is likely to be formed between the socket and the ceiling surface, and it is also weak against torsional force in the direction B in the figure, so the dimensional accuracy of the socket spacing tends to deteriorate.

Additionally, in order to prevent this, reinforcing ribs 12 are provided on the mounting piece 4 as shown in FIG. There was a problem that when inserting the socket 9 from one side and then inserting the socket 9a from the other side, the socket 9a got caught on the reflector plate 7 and was difficult to insert, making the installation work difficult.

The present invention was developed with the aim of solving these conventional problems, and includes a socket mounting piece that has a socket mounting part and a reflector mounting part and is wider than the width of the instrument body, and has a socket mounting piece at both ends. forming mounting pieces bent inward to form a socket base having a substantially inverted triangular shape, disposing the socket bases at both ends of the instrument body and attaching the tips of each mounting piece to the instrument body;
In a lighting device in which a reflector is attached to the reflector attaching portion of the socket base, an engaging piece is provided protruding from the socket attaching piece,
The retaining piece is inserted into the support hole formed on the side surface of the main body of the instrument, and in the free state there is a bending allowance between the upper edge of the support hole and the upper end of the retainer piece, and when the reflector is attached, the retainer is supported. It is characterized in that the lower end of the retaining piece is locked to the lower edge of the hole.

In the present invention, sufficient strength is maintained by the engaging piece against downward force and twisting force applied to the socket mounting piece, and the bending allowance of the support hole prevents the socket mounting piece from bending against upward force. To provide a lighting fixture which does not cause a gap between a reflector and a ceiling surface or deteriorate the dimensional accuracy of socket spacing, and allows easy installation of the reflector.

Embodiments of the present invention will be described below with reference to FIGS. 3 and 4.

In the figure, the basic shape of the socket base 5 is the same as that in FIG. 1 shown as a conventional example, and the same parts are given the same numbers as in FIG. 1, and detailed explanation will be omitted.

The socket mounting piece 1 of the socket base 5 is provided with reinforcing pieces 15 and 16 by bending both side edges upward, and an engaging piece 17 is integrally projected from the upper edge of one of the reinforcing pieces 15 toward the device body 6. It's a powerful design.

Correspondingly, a support hole 19 is provided in the side surface 18 of the instrument main body 6, and the engagement piece 17 is inserted and locked into this support hole 19, and the vertical dimension of the support hole 19 is Piece 17
A deflection allowance C is provided, which is larger than the vertical dimension of.

Furthermore, a locking claw 4a and a notch 4b are formed on the edge of the mounting piece 4, and a bridge piece 6a and a fixing claw 6b are formed on the upper surface of the instrument body 6, and the locking claw 4a is inserted into the bridge piece 6a. death,
By fitting the fixing claw 6b into the notch 4b and caulking,
The socket stand 5 is attached to the instrument body 6.

Here, the reflector plate (not shown in FIG. 3) is attached using the same procedure as in FIG. 2, but in this embodiment, the engaging piece 17 provided on the socket mounting piece 1 is hole 1
9, the strength is increased against the downward force in the direction A or the twisting force in the direction B shown in FIG.

Therefore, since the socket base 5 hardly deforms, there is no gap between the reflector and the ceiling when the reflector is lowered, and the dimensional accuracy of the socket spacing is maintained. 1, the socket (not shown in FIG. 3) attached to the socket attachment piece 1 moves upward by an amount corresponding to the deflection C, making it possible to easily attach the reflector.

As mentioned above, in the present invention, the lower end of the engaging piece provided on the socket mounting piece of the socket base is locked to the lower edge of the support hole of the device body, so the socket base can resist downward force and twisting force. This has the advantage that there is no gap between the attached reflector and the ceiling surface, and that the dimensional accuracy of the socket spacing can be improved. Since there is a bending allowance between the socket and the socket base so that it can bend upwards, the socket will not get stuck on the reflector when installing the reflector, making the installation work easier. It has its advantages.
