Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a lighting fixture frame that is applied to an opening in a light-transmitting member that covers the entire surface of a lamp of a lighting fixture that is directly attached to a ceiling.

[Background Art] Conventionally, in the case of a light-transmitting member of a lighting fixture for direct ceiling mounting, such as a lighting fixture frame provided in a globe, the frame member 30 is clamped and die-cut in the thickness direction as shown in FIGS. 6 and 7. The frame member 30 is molded by injection molding, and an auxiliary fitting 31 is attached to the inside thereof using screws (not shown), thereby forming a groove 32 for storing insect-proof packing on the upper end side of the frame member 30, and a transparent member retaining member on the lower end side. A stop groove 33 is formed. At the same time, the frame member 30 adjacent to the connecting piece 33a of the auxiliary metal fitting 31
interconnect each other. Then, the auxiliary fitting 31 is provided with a fitting 34 to be attached to the instrument main body 35, and by attaching this fitting 34 to the instrument main body 35, the hanging part 36 on the periphery of the instrument main body 35 is attached to the insect-proof packing 37 of the insect-proof packing storage groove 32. In close contact. Further, the globe 38 is fitted into the light-transmitting member locking groove 33.

However, since the frame member 30 of this lighting fixture frame is injection molded, the longitudinal direction of the frame member 30 is restricted by the mold, and it is difficult to easily manufacture frames of different lengths. Ta. Furthermore, the number of parts constituting the lighting fixture frame increases, which increases costs.

On the other hand, if the entire frame is formed by extruding and molding the frame member in its longitudinal direction, there is no restriction in the longitudinal direction compared to injection molding, and items of different lengths can be easily molded. Therefore, frames with different sizes can be easily manufactured.
Furthermore, since the insect-proof gasket storage groove and the light-transmitting member locking groove can be formed at the same time, no auxiliary metal fittings are required. However, processing is required to provide a fixture for fastening the lighting fixture frame and the fixture body 35, and since the strength of the whole is weakened, there is a risk that the lighting fixture frame may fall from the fixture body 35 due to elastic deformation. be.

[Purpose of the invention] The purpose of this invention is to provide a frame for a lighting fixture that can be easily manufactured with frames of different sizes, that makes it easy to attach the fixture to the fixture body, and that does not easily come off from the fixture body. The goal is to provide the following.

[Disclosure of the invention] This invention consists of a pair of first insect repellent gaskets that are extruded and have a first insect repellent packing storage groove formed on the upper end side and a first light-transmitting member locking groove formed on the lower end side.
a pair of second frame members formed by a mold that is clamped and cut in a direction perpendicular to the longitudinal direction and have corner portions connected to the first frame member at both ends; The second frame member is attached to the inside of these second frame members and is attached to the upper end side of the second frame member.
A second insect repellent gasket storage groove is formed with the frame member, which is continuous with the first insect repellent gasket storage groove; This device includes a pair of reinforcing metal fittings that form a continuous second light-transmitting member locking groove, and a fitting that is provided on these reinforcing metal fittings and is attached to the instrument body.

According to this invention, since the first frame member is extruded, the length of the first frame member can be easily set, and products with different frame shapes can be manufactured easily, allowing product expansion. As it becomes easier, the first
Since the first insect-proof gasket housing groove and the second light-transmitting member locking groove are formed in the frame member, conventional reinforcing metal fittings are not required, and therefore the number of parts can be reduced and assembly can be facilitated. In addition, the second frame member is formed by a mold that is clamped and cut in a direction perpendicular to the longitudinal direction, and reinforced by forming a second insect-proof packing storage groove and a second light-transmitting member locking groove on the inside thereof. Since the metal fittings are provided and the reinforcing metal fittings are provided with attachments to the fixture body, the structure of the second frame member is not complicated and has excellent strength, and elastic deformation makes it difficult for the lighting fixture frame to come off from the fixture body. Also, processing to provide a fixture is not required.

Embodiment An embodiment of this invention will be explained based on FIGS. 1 to 4. That is, this lighting fixture frame is extruded and has a pair of first insect repellent gasket storage grooves 1 formed on the upper end side and a first translucent member locking groove 2 formed on the lower end side. A pair of frame members 3, 4 formed by a mold that is clamped and cut in a direction perpendicular to the longitudinal direction, and corner portions 5 connected to the first frame members 3, 4 are formed at both ends thereof. The second frame members 6, 7 are attached to the inside of the second frame members 6, 7, and the second frame members 6, 7 are attached to the upper end side of the second frame members 6, 7 together with the second frame members 6, 7. A second insect repellent gasket storage groove 8 is formed which is continuous with the first insect repellent gasket storage groove 1, and the first transparent member locking groove 2 is formed along with the second frame members 6 and 7 on the lower end side. A pair of reinforcing metal fittings 10 and 11 forming a second light-transmitting member locking groove 9 that is continuous with the
and a fixture 13 provided on these reinforcing metal fittings 10, 11 and attached to the instrument main body 12.

The second frame members 6 and 7 are formed by injection molding. Further, the first frame members 3 and 4
The second frame members 6 and 7 are connected to each other by connecting pieces 14 formed at both ends of the reinforcing metal fitting 10. The insect repellent gasket 15 is stored in the first insect repellent gasket storage groove 1 and the first insect repellent gasket storage groove 8. A flange 16a of a light-transmitting member 16, which is an example of a glove, is inserted into the first light-transmitting member locking groove 2 and the second light-transmitting member locking groove 9 and is locked therein. The fixture 13 is an example of a claw metal fitting, and the fixture body 12 is provided with a rotatable receiving bracket (not shown). It can be installed by rotating the receiving metal fitting with the claw and hooking the claw into the hole in the receiving metal fitting. In addition, a push button 13 provided on the fixture 13
