[Detailed Description of the Invention] Industrial Application Field This invention relates to a bathroom vanity with a lighting fixture, and particularly relates to a structure for attaching a lighting fixture to a vacuum-formed resin cabinet for a bathroom vanity.

Conventional technology Bathroom vanities that are commonly used in households are generally made of a vacuum-formed, thin-walled resin cabinet with a mirror, straight-tube fluorescent lamp lighting equipment, switch box, etc. attached to the front of the cabinet. It is. The lighting equipment consists of a main body to which a ballast and a straight tube fluorescent lamp are attached, and a shade.The lighting equipment is installed by fitting the main body into a recess drawn in the front surface of the upper part of the resin cabinet and fixing it with screws. A structure in which a shade is fitted into the opening of the recess is common, and a specific example thereof will be described below with reference to FIGS. 5 to 7.

In FIGS. 5 and 6, 1 is a resin cabinet, in which a heated and softened resin plate is squeezed along the uneven surface of the mold and brought into close contact with a mold (not shown) having irregularities in a desired shape. It is manufactured using a vacuum forming method where it is cured and removed from the mold. The resin cabinet 1 has a bottomed recess 2 for mounting a lighting device, which is drawn at the front of the upper part and has a substantially rectangular shape on the front, a bottomed recess 3 for mounting a mirror, which is drawn at the front of the center part, and a switch box is mounted at a part of the lower part. It has part 4. 5 is a lighting fixture for a straight tube fluorescent lamp fitted into the recess 2; 6;
numeral 7 is a mirror fixed to the bottom of the recess 3 by pasting and screwing, and 7 is a switchbox fitted and fixed in the switchbox mounting part 4, on which a lamp blinking switch 8 of a lighting fixture 5, an outlet 9, etc. are mounted. Reference numeral 10 denotes a back plate such as a plywood board that closes the back opening of the resin cabinet 1.

As shown in FIG. 7, the lighting fixture 5 includes a rectangular gutter-shaped fixture body 11 made of sheet metal, sockets 12, 12 fixed to both front ends of the fixture body 11, and a ballast 13 attached to the back side of the fixture body 11. and starter 14
, a straight tube fluorescent lamp 15 fitted into sockets 12, 12, and a horizontally long shade 16.
The main body 11 of the instrument consists of a front plate 11a and side plates 11b, 11b bent at right angles.
L-shaped mounting legs 1 with inward cut-and-raised parts
1c, 11c are formed with a height slightly protruding from both side plates 11b, 11b.

This lighting fixture 5 is installed in the recess 2 of the resin cabinet 1.
It is installed in the following manner. First, fit the device main body 11 from which the straight tube fluorescent lamp 15 has been removed into the bottom of the recess 2, and attach the mounting legs by using the square holes 17, 17 formed by cutting out the mounting legs 11c, 11c in the front plate 11a. 11c, 11c to the bottom of recess 2 with tap screw 1
8 and 18, and the both side plates 11b and 11b of the instrument main body 11 are brought into contact with the bottom plate 2a of the recess 2 and the longitudinal wall plates 2b and 2b and fixed. Next, the straight tube fluorescent lamp 15 is attached to the sockets 12, 12 of the device body 11, and then the shade 1 is inserted into the opening of the recess 2.
For example, both ends of the shade 16 are fixed by screwing decorative screws 20, 20 into screw holes 19, 19 provided in the overhanging portions at both ends of the recess 2.

Problems to be Solved by the Invention Incidentally, the recess 2 for mounting the lighting fixture in the resin cabinet 1 has a depth equal to or greater than the height of the fixture body 11, and is formed by drawing both wall plates 2b, 2b at almost right angles. , the height of the device body 11 is at least as high as the stabilizer 13
, the depth during drawing of the recess 2 becomes larger and the wall thickness of the recess 2 becomes thinner than the other parts.Especially, the corner part of the bottom plate 2a becomes even thinner and tends to become mechanically weak. It was hot. Therefore, when the heavy instrument main body 11 is screwed and fixed in the recess 2, the bottom plate 2a is thin and the instrument main body 11
The vibration of the ballast 13 when the lamp was lit was transmitted to the recess 2 and amplified especially at the thinner corners of the bottom plate 2a, causing noise and emitting outside. . In addition, in order to prevent such problems from occurring, the vacuum forming conditions for the resin cabinet 1 are made stricter to ensure a stable wall thickness of the recess 2, but this makes it difficult to mold the resin cabinet 1, resulting in poor productivity. Moreover, no matter how strict the molding conditions are, it is not possible to completely prevent the above problems from occurring, and structural improvements have been desired.

Means for Solving the Problems The present invention has been made in view of the above request, and the technical means of the present invention to achieve this request is a substantially rectangular shape formed on the front surface of the upper part of a resin cabinet for a bathroom vanity. In a device in which the main body of a lighting fixture for a bathroom vanity is fitted into the bottom recess, the opposing wall plates in the longitudinal direction of the recess are provided with a stepped portion approximately in the middle to form a tapered shape that opens outward; The main body of the device is mounted on the stepped portion and screwed to the bottom plate of the recess.

Effect: According to this technical means, the concave part of the resin cabinet for attaching lighting equipment becomes trapezoidal, which is easy to draw, so that the wall thickness of this concave part can be ensured to be sufficient without making the vacuum forming conditions of the resin cabinet strict. This makes it easier to mold the resin cabinet. In addition, due to the structure in which the main body of the device is placed on the stepped part of the recessed wall plate,
The height of the instrument body can be reduced, and the material and weight of the instrument body can be reduced.
