Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a buttful fixing device for lighting equipment,
The present invention relates to a configuration for attaching a baffle plate to a buffle support.

[Technical background of the invention and its problems]

The conventional fastening device for this type of lighting equipment is
As shown in FIGS. 1 and 2, an engagement hole 3 is formed in the middle of both side surfaces 2 of a roughly V-shaped buttful support 1, and a buffle plate 4 is provided at the center of the upper edge of the buttful support 1. A substantially V-shaped engagement recess 5 is formed in accordance with the shape of the engagement recess 5 , and projections 6 that engage with the engagement hole 3 are brought into contact with the upper portions of both side edges of the engagement recess 5 . The engagement recess 5 of is engaged with the top of the buttful support 1, and the engagement hole 3 of this buttful support 1 is
A structure is adopted in which the buttful plate 4 is fixed to the buttful support 1 by engaging the protrusion 6 with the part. In this structure, it is necessary to ensure that the bending angle θ ₁ of the V-shape of the buttful support 1 and the notch angle θ ₂ of the engagement recess 5 of the buttful plate 4 match, and high processing accuracy is required. A gap is likely to occur at the joint 7 between the mating recess 5 and both side surfaces 2 of the support 1, and the full plate 4
When attaching the buttful plate 4 to the buttful support 1,
The protrusions 6 rub against the outer surface of the buttful support 1,
Scratch marks occur, impairing the appearance, and a large number of engagement holes 3 must be formed in the buttful support 1, and strict positional accuracy is required for each engagement hole 3, which requires mold cost. Moreover, since the buff-full plate 4 has a notch formed by the engagement recess 5 at the center of its upper edge, the strength of the buff-full plate 4 is reduced, and it has the disadvantage that it is easily bent during processing or assembly.

[Object of the Invention] The present invention has been made in view of the above-mentioned drawbacks, and it is an object of the present invention to provide a buttful fixing device for lighting equipment that is aesthetically pleasing, simple in structure, easy to assemble, strong, and inexpensive. .

[Summary of the invention]

The present invention includes a buttful plate in which a pair of protrusions are formed on the upper edge of the buttfull plate, the outer edge being inclined outwardly with respect to the upper edge, and a substantially V-shaped
and a buttful support having elasticity that allows the angles of the ends to be varied inwardly using the apex of the letter shape as a fulcrum, and having slits formed at predetermined intervals across the apexes, the buttful support. A plurality of buttful plates are fitted into each of the slits, and the outer periphery of the protrusion of the buttful plate is elastically pressed against the inclined inner surface of the inner edge of the slit, thereby fixing the plurality of buttful plates to the buttful support. When assembling, one of the pair of protrusions of the buttful plate is fitted and engaged with the inner surface of the inner end of the slit of the buttful support, and then the other protrusion of the buttful plate is expanded using the elasticity of the buttful support. The slit is fitted and engaged with the inner surface of the slit.

[Embodiments of the invention]

Next, the configuration of an embodiment of the present invention will be explained with reference to the drawings.

Reference numeral 10 denotes a buttful support, which consists of both end portions 11, 11 bent into a substantially V-shape, and has elasticity that allows the angles of the ends to be varied inwardly using the apex of the substantially V-shape as a fulcrum. . A plurality of slits 12 are formed at predetermined intervals on both side surfaces 11, 11 of the buff-full support 1 over the vertex.

Next, reference numeral 13 is a horizontally long board-shaped buttful board, and the upper edge 14
A pair of symmetrical protrusions 15 spaced apart from each other in the center of the
15 is provided protrudingly. The protrusions 15, 15 have an outer edge 16 that is inclined outwardly with respect to the upper edge 14 of the buttful plate 13, and the upper part of the inner edge 17 of the protrusions 15, 15 is formed into an arcuate edge 18. .

Next, the operation of this embodiment will be explained.

When assembling, as shown in FIG. 9, insert the central part of the buffle plate 13 into the slit 12 of the buffle support 10, and insert the outer edge 16 of one protrusion 15 from the inner edge of the slit 12 of the buffle support 10. When the other protrusion 15 side of the buff-full plate 13 is rotated upward (in the direction of the arrow in FIG. 9), the arcuate edge 18 of the inner edge 17 of the protrusion 15 engages with the inner edge 19 of the slit 12. , the buffful support 10 elastically expands and changes from the angle θ to the angle θ _a , and the outer edge 16 of the protrusion 15 moves inward of the inner edge 19 of the slit 12, and in this state. The angle between both side surfaces 11 of the buttful support 10 is elastically restored to the angle θ, and the outer edge 16 of the protrusion 15 is engaged inwardly than the inner edge 19 of the slit 12, and the outer edge of both protrusions 15, 15 Attach full support 1 to part 16
The inner surfaces of both side surfaces 11, 11 of 0 are elastically pressed together. Note that the protrusion 1 is
5 and 15 are both side parts 11 of the buttful support 10,
Since the outer surface of the buttful support 10 is not rubbed, the outer surface of the buttful support 10 is not damaged.

Furthermore, after attaching the buttful plate 13 to the buttful support 10, both protrusions 1 are attached as shown in FIGS.
5 and 15 in a direction perpendicular to the length direction of the slit 12, the upper edge 1 of the buff-full plate 13
4 is abuttingly engaged with the inner edge 19 of the slit 12,
The upper edges of each cross-full plate 13 are aligned, and the cross-full plate 1
3 is obtained, the line balance is improved, and the fixing strength of the buttful plate 13 is increased.

Note that by forming the upper part of the inner end portion 17 of the protrusions 15, 15 of the buttful plate 13 into an arcuate edge 18, the buttful support 10 can be placed on a table with the apex facing upward, and the buttful plate 1
3 is engaged with the slit 12, the arcuate edges 18 of the protrusions 15, 15 slide in, making assembly easier.

As shown in FIG. 4 and FIG.
Although this embodiment is designed to suspend and support the lighting fixture below, the buttful support 10 may also serve as a reflector for the fixture 21, as shown in FIG.

〔Effect of the invention〕

According to the present invention, a buffle plate is fitted into each slit formed over the apex of a substantially V-shaped buffle support, and a pair of buffle plates are provided on the inclined inner surface of the inner edge of the slit and protrudes from the upper edge of the buffle plate. Since the outer edge of the protrusion that is inclined outward is elastically pressed against the upper edge of the buttful plate, there is no gap at the joint between the buttful plate and the buttful support, which improves processing accuracy and assembly accuracy. It is easy to assemble, and the protrusions of the buttful plate do not come into sliding contact with the outer surface of the buttful support during assembly, so the appearance is not impaired. It also maintains strength and can be obtained at low cost.
