In a lighting fixture cover (7) having a curved cover (7) formed by extrusion and having engaging portions for attachment at the upper and lower ends of the main body, reinforcement is provided continuously to the engaging portions at the upper and lower ends and continuous in the extrusion direction. The rims 7d and 7e are formed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cover for a lighting fixture that is used by being attached to the upper portion of a makeup mirror or the like, and particularly to a lighting cover formed by extrusion molding.

[0002]

[Prior art]

 The extrusion molding method is a typical molding method that is widely used for molding thermoplastic resins. With this method, it is not necessary to measure the amount of resin in each molding cycle, and the resin raw material is put into the hopper. Since it can be continuously and automatically molded, products can be efficiently mass-produced.

According to this manufacturing method, all the products must have the same cross-section, and mainly electric wires, antenna cords for televisions, feeders, tubes, hoses, sheets or lighting covers are manufactured. There is.

FIG. 6A shows a lighting cover formed by such extrusion forming, and a lighting cover 21 is attached so as to cover the front surface of the lighting fixture 20 provided on the upper part of the washstand or the like. The cover 21 is provided with engaging portions 22 at the upper and lower ends of the cover 21 for maintenance, and the engaging portions 22 are detachably attached by locking claws formed on the left and right sides of the lighting fixture 20.

However, in the case of a lighting cover having a curved surface as shown in FIG. 6 (a), it is weaker in strength than a cover having a rectangular cross section in particular, and as shown by a dashed line in FIG. A downward warp is likely to occur.

As a countermeasure against this, for example, a method of increasing the thickness of the member itself to improve the rigidity of the entire lighting cover, or providing an extruded lighting cover with a reinforcing member such as a metal plate can be considered.

[0007]

[Problems to be solved by the device]

 However, if the entire member of the lighting cover is thickened, the weight also increases accordingly, the workability at the time of mounting is deteriorated, and the cost increases. Also, providing a metal plate or the like for reinforcement requires a new step, and it is difficult to fully exhibit the merit of extrusion molding that the product can be mass-produced efficiently.

Therefore, the problem to be solved in the present invention is to obtain a means that can be manufactured by extrusion molding and that can effectively prevent warping of the lighting cover with a relatively simple structure.

[0009]

[Means for Solving the Problems]

 The present invention relates to a lighting cover in which engaging parts for attachment are formed at the upper and lower ends of a curved cover body formed by extrusion molding, and a reinforcing rim that is continuous with the engaging parts at the upper and lower ends and is continuous in the extruding direction. By forming the, the above problems are solved. This reinforcement rim may have the same thickness as the cover body, or the thickness of the reinforcement rim alone may be increased.

[0010]

[Action]

 In the lighting cover of the present invention, since the reinforcing rim is connected to the engaging portion of the cover body, it can be molded by the conventional extrusion molding process, and by increasing or decreasing only the thickness of the reinforcing rim, It is possible to adjust the rigidity according to the width of the cover opening.

【Example】

 FIG. 1 is a perspective view showing an example in which the present invention is applied to a vanity.

In FIG. 1, reference numeral 1 is a washbasin equipped with two balls, large and small, and 2 is a makeup mirror fixed to the upper portion of the washbasin 1. The makeup mirror 2 includes a frame member 3, a mirror body 4 attached to the front surface of the frame member 3, and a lighting device 5 attached to the upper end of the mirror body 4.

FIG. 2 is a cross-sectional view of the vanity table shown in FIG. 1 taken along the line AA. A part 3b is provided. A second locking portion 3c is provided on the frame member 3, and the lighting cover 7 is detachably attached to the first and second locking portions 3b and 3c. In addition, 6 is a lighting fixture main body provided with a lamp.

With reference to FIG. 3 showing only the lighting cover 7, the lighting cover 7 of the present embodiment has first and second locking members at the upper and lower ends of a curved cover body 7a formed by extrusion molding. The 1st and 2nd engaging part 7b, 7c which engages with the part 3b, 3c is formed. In addition, reinforcing rims 7d and 7e for preventing warpage are integrally formed so as to be continuous with the first and second engaging portions 7b and 7c and continuous in the extrusion direction.

With such a structure, molding can be performed in the conventional extrusion molding process, and the reinforcing rims 7d and 7e become one beam, so that the lighting cover 7 is effectively warped particularly in the longitudinal direction. Can be prevented. In this embodiment, since the width of the lighting cover 7 in the front direction is not so long as to cause warpage, the thickness of the reinforcing rims 7d and 7e is set to the cover body 7a and the first. The second engaging portions 7b and 7c have the same thickness, but of course, the present invention is not limited to this, and the lighting cover 7 may be particularly thick depending on the width in the frontal direction.

FIG. 4 is a cross-sectional view of the vanity shown in FIG. 1 taken along the line BB, showing a cross section of the joint between the vanity 1 and the makeup mirror 2.

As shown in the figure, at the joining portion between the washbasin 1 and the makeup mirror 2, a front piece 10a exposed to the front side shown in the perspective view of FIG. ) From which a T-shaped decorative edge 10 having an insert piece 10b protruding in a right angle direction is attached.

The insert piece 10b of the decorative edge 10 has a long hole 10c for screw attachment, which is long in the frontage direction, at a position corresponding to the screw hole 3d for attaching the decorative edge formed on the lower surface of the frame member 3. Has been formed. Further, a cutout 10d slightly thicker than the head of the mounting screw 11 is formed at the position where the elongated hole 10c is formed on the lower surface of the insertion piece 10b.

With such a structure, as shown in FIG. 4, when fixing the decorative edge 10 to the lower surface of the makeup mirror 2 with the screw 11, the center positions of the screw hole 3d of the frame member 3 and the long hole 10c of the decorative edge 10 are positioned. Even when the placement is deviated due to processing tolerances or the like, by shifting the decorative edge 10 in the front direction, it is possible to attach the decorative edge without causing slack in the decorative edge.

[0020]

[Effect of device]

 As described above, in the lighting cover of the present invention, since the reinforcing rim is continuously provided to the engaging portion of the cover body, the conventional extrusion molding process can effectively prevent the warpage. In addition, by increasing or decreasing only the thickness of the reinforcing rim, it is possible to adjust the rigidity according to the frontage width of the cover.
