[0002]
[Prior art]
A lighting fixture using a fluorescent lamp will be described with reference to FIG. 1. A lamp socket and a globe mounting part are provided on the lower surface of a circular main body, and the fluorescent lamp is mounted on the lamp socket. It has a structure with a glove attached so as to cover. For example, two glove attachment parts are provided so as to face the outer peripheral part of the main body, or three glove attachment parts are provided on the outer peripheral part of the main body at intervals of 120 degrees.
[0003]
Conventional globe mounting parts are made of resin and metal. As shown in the cross-sectional view of FIG. 5, the resin globe mounting part has a structure in which a resin claw 51 is slidably inserted into a metal case 54 via a spring 53 and a metal lid 55 is attached. . The metal glove attachment component has a structure in which the resin claw shown in FIG. 5 is replaced with a metal claw.
[0004]
[Problems to be solved by the invention]
The conventional plastic glove mounting parts are damaged if the deterioration of the resin due to secular change and breakage such as cracking due to insufficient strength occur, and if the glove of the luminaire falls and there is a person under the luminaire, There was a possibility of defeating. In addition, the metal glove attachment component has a risk that the glove is scratched and cracked because the metal is in direct contact with the glove.

DETAILED DESCRIPTION OF THE INVENTION
Next, the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing a first embodiment of the present invention. The lighting fixture of this embodiment is provided with a lamp socket (not shown) and a globe mounting part 3 on the lower surface of a circular main body 1, a fluorescent lamp 4 is mounted on the lamp socket, and the fluorescent lamp 4 is covered on the globe mounting part 3. In this way, the glove 2 is attached. For example, two globe attachment parts 3 are provided on the outer periphery of the main body 1 so as to face each other, or three are provided at intervals of 120 degrees. The feature of this embodiment is that the globe mounting part 3 is reinforced by putting a metal frame in a resin claw.
[0009]
FIG. 2 is an exploded perspective view of the glove mounting component 3 according to the present invention, and FIG. 3 is a cross-sectional view of the glove mounting component in an assembled state. As shown in FIG. 2, the glove attachment component includes a resin claw 11, a metal frame 12, a spring 13, a metal case 14, and a metal lid 15. The resin claw 11 includes a box-like portion 11a having triangular projections 11e at both ends, and two plates extending in parallel in a right-angle direction from a side surface opposite to the projection 11e of the box-like portion 11a. The portion 11b and the intermediate plate portion 11c provided so as to be orthogonal to the middle of these plate portions 11b are integrally formed.
[0010]
The resin claw 11 is formed with a groove 11d that does not reach the lower end as shown in FIG. A metal frame 12 having a shape as shown in the figure is inserted into the groove 11d of the resin claw 11 and combined together. As shown in the drawing, the metal frame 12 has a U-shaped portion and a protruding portion similar in shape to the triangular protruding portion 11e of the resin claw 11 described above at the tip portion bent so as to open on both sides. It has a formed shape. The metal frame 12 is made slightly smaller than the outer shape of the resin claw 11, and in a component in which the resin claw 11 and the metal frame 12 are combined, the outer end portion is made of resin and the metal frame Is not exposed on the outside of the combined part.
[0011]
A combination part of the metal frame 12 and the resin claw 11 is slidably mounted on a metal case 14 via a spring 13. As shown in the figure, the case 14 is a rectangular box that is open at one end and has a flat plate portion 14c that is open on both sides at the top, and an intermediate plate 14d that is perpendicular to the side wall 14b is provided at the middle of the box. ing. A gap is formed between the side wall 14b of the case 14 and the intermediate plate 14d, and the plate portion 11b of the resin claw 11 and the side portion 12b of the metal frame 12 are inserted into the gap.
[0012]
A spring 13 is mounted between the intermediate plate 14 d of the case 14 and the intermediate plate portion 11 c of the inserted resin claw 11. There is a space between the back wall 14a of the case 14 and the back end surface 12c of the combination part of the resin claw 11 and the metal frame 12, and the combination part with the resin claw 11 and the metal frame 12 is the case 14. On the other hand, it is configured to be slidable back and forth by expansion and contraction of the spring 13. Finally, the metal lid 15 is attached to complete the glove attachment part. FIG. 3 is a cross-sectional view showing the glove attachment part 3 that has been assembled. The globe attachment component 3 is attached to the lower surface side of the main body 1.
[0013]
Next, the operation | movement of attachment and removal of the glove | globe in this embodiment is demonstrated. The globe attachment component 3 is fixedly attached to the main body 1 by using screws or the like as shown in FIG. When the combination part of the resin claw 11 and the metal frame 12 is pressed in the right direction in FIG. 3, for example, the spring 13 contracts and the glove attachment part 3 is shortened. When the pressure is stopped, the elastic force of the spring returns. When the globe 2 is pushed upward from the lower side of the main body 1, the outer peripheral portion of the globe 2 comes into contact with and presses the inclined surface 11 f of the protruding portion 11 e of the resin claw 11, and the spring 13 is generated by the horizontal component force generated at that time. When the outer periphery of the globe 2 passes through the upper surface of the protruding portion 11e, the spring 13 is stretched by its elasticity and the globe is engaged. When removing the glove, this operation can be reversed. In this way, the glove can be attached and detached.
[0014]
As described above, in the first embodiment of the present invention, the metal frame is inserted into the resin claw of the glove attachment part of the lighting fixture for reinforcement, and the metal frame is combined with the metal case. Even when the resin claw is deteriorated and damaged, the metal frame is caught on the case, and the glove can be held and the glove can be prevented from dropping. Further, since the metal frame is not exposed at the portion where the glove is engaged, there is no risk of scratching the glove.
[0015]
Next, a second embodiment of the present invention will be described. FIG. 4 is a cross-sectional view showing a globe mounting component according to a second embodiment of the present invention. Other parts of the lighting fixture are the same as those of the first embodiment shown in FIG. Conventionally, metal glove attachment parts are known, but the feature of this embodiment is that the tip part of the metal glove attachment part engaged with and in contact with the glove is coated with resin. As shown in FIG. 4, the claw portion is formed of a metal claw 41 and is slidably attached to the metal case 44 via a spring 43. The tip of the metal claw 41 is covered with a resin 42. As the resin coating method, for example, a resin member molded in a desired shape may be put on the tip portion, or a resin film may be formed on the tip portion. The glove attachment part formed in this way is attached to the luminaire main body as shown in FIG.
[0016]
Since this embodiment has a structure in which the tip of the metal glove mounting part with which the glove is engaged is covered with resin, the glove does not directly contact the metal claw, and the glove is damaged. There is no danger of attaching, and since the claw portion is made of metal, the strength is sufficient, and there is an effect that the danger of dropping the glove can be prevented.
[0017]
【The invention's effect】
As described above in detail, in the present invention, since the metal frame is reinforced by inserting the resin frame into the resin claw part of the resin glove mounting part, it is possible to prevent the glove from dropping when the resin glove mounting part is damaged. . Therefore, if the glove fitting is damaged when a person is under the luminaire, the glove may fall and injure the person normally. Is held in the instrument body, eliminating the risk of injury to humans.
[0018]
Moreover, since this invention coat | covered resin in the part which the glove of the metal claw tip part of metal glove attachment parts engages, there exists an effect that it can prevent that a glove is damaged.
