Description

[Detailed description of the invention] Industrial application field This invention relates to a study desk with a lighting device used for studying, reading, etc.

BACKGROUND TECHNOLOGY Study desks are generally equipped with shelves and a lighting unit, and the lighting unit of this study desk includes a first lighting fixture for a straight tube fluorescent lamp that illuminates the entire desk top, and a first lighting fixture for a straight tube fluorescent lamp that illuminates the entire desk top. Generally, it consists of three parts: a second lighting fixture (spotlight) for selectively illuminating an incandescent lamp, and an operation box containing a switch for operating the lamps of the first and second lighting fixtures. In addition, the above lighting unit is
An integrated lighting unit with integrated lighting units and a separate lighting unit with a separate operating box have been used, and three of these lighting units are fixed to a shelf on a desk with screws.

For example, FIG. 6 shows a study desk with a shelf a having an integrated lighting unit, and FIG. 7 shows a study desk with a shelf b having a separate lighting unit with an operation box.

In the study desk a in FIG. 6, 1 is the desk body, 2 is a shelf fixed upright on the desk body 1, and 3 is an integrated lighting fixture fixed to the bottom surface of one shelf board 4 of the shelf 2. The unit includes a first luminaire 6 having a straight tube fluorescent lamp 5 and a second luminaire 8 having an incandescent lamp 7.
and switches 9, 9' for operating these lamps.
The three points of the operation box 10 having the following functions are integrated. The second lighting fixture 8 is called a spotlight, and is attached to the first lighting fixture 6 so as to be slidable in the left-right direction, for example. The operation box 10 has a switch 9 for blinking the fluorescent lamp 5 of the first lighting fixture 6, a switch 9' for blinking the incandescent lamp 7 of the second lighting fixture 8, and two switches as necessary.
It has two built-in service outlets 11, 11, which are connected to the first and second lighting devices 6, 8 with a three-wire wiring cord 12 as shown in the wiring diagram shown in FIG. It is connected to a commercial AC power source 14 through a power cord 13 .

The study desk b in FIG. 7 has first and second lighting fixtures 6' and 8' similar to those described above on the lower surface of one of the two shelf boards 15 and 15' of the shelf 2' fixed on the desk body 1. , has a separate operation box type illumination unit 16 having an operation box 10' fixed to the lower surface of the other side.

Problems that the invention aims to solve: The above-mentioned study desk with a shelf and a lighting unit is useful for students, especially in lower grades, because the shelf can be used to attach a lighting unit or in place of a bookcase. They are popular because they are convenient and easy to use for children, but as children grow older, there is a general tendency for the shelves in study desks with shelves to become a physical and psychological hindrance as children grow older. Therefore, it is practical to have a study desk that has a removably fixed shelf on the desk itself using bolts, etc., so that when the child is in the lower grades, the shelf is attached, and when the child is in the upper grades, the shelf can be removed freely. It is becoming popular because of this.

However, if you remove the shelf from the desk body, the lighting unit attached to the shelf will also be removed. I'm trying to light it up with new lighting equipment. However, this wastes the lighting unit directly attached to the shelf and is extremely uneconomical. However, it is difficult to remove the lighting unit from the shelf and reuse it because of the structure and appearance of the existing lighting unit.

Means for solving the problems This invention was made in view of the above problems.
A desk body, a shelf detachably attached to the desk body, a lighting fixture installed on the desk body separately from the shelf, and a switch connected to the lighting fixture with a wiring cord to operate the lamp blinking operation of the lighting fixture. A built-in operation box is provided, and the shelf and the operation box are characterized in that the shelf and the operation box have engaging means for removably engaging with each other.

Function Even if you remove the shelf from the desk body, the lighting fixture remains on the desk body, and the control box for this lighting fixture can be removed from the shelf and moved to the desk body or any other location, making it easier to use the desk. It is economical for people and increasingly convenient to use.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

In the study desk shown in Figures 1 and 2, 17
18 is a shelf removably attached to the desk body 17 by bolting or the like; 19 is a lighting fixture installed on the desk body 17 separately from the shelf 18; 2;
0 is an operation box for controlling the lamp of the lighting fixture 19 to blink.

The lighting fixture 19 includes, for example, a support 21 fixed on the desk body 17 with screws or the like, and a first straight tube fluorescent lamp swingably connected to the upper end of the support 21.
It is composed of a lighting fixture 22 and a second lighting fixture 23 for an incandescent lamp, which is slidably attached to the first lighting fixture 22.

The operation box 20 has two switches 24, 24' and service outlets 25, 2 as before.
5 is built in, one switch 24 controls the blinking of the fluorescent lamp 26 of the first lighting fixture 22, and the other switch 2
4' is used for blinking the incandescent lamp 27 of the second lighting fixture 23. The operation box 20 is connected to the first and second lighting devices 22 and 23 by a wiring cord 28 using the same circuit as in FIG. 8, and is connected to a commercial AC power source by a power cord 29. This operation box 20 is characterized in that it is attached to the shelf 18 via detachable engagement means.

For example, a mounting bracket 31 for an operation box engaging means as shown in FIG. 3 is fixed to the lower surface of a shelf board 30 located at the lower right side of the shelf 18 with screws. The mounting bracket 31 holds the rectangular operation box 20 inserted from the front so as to embrace it from both sides. Although not shown, the operation box 20 held by the mounting bracket 31 is connected to the mounting bracket 3 by engaging with a claw or screwing.
1, and when this temporary fixing means is removed, the operation box 20 can be easily removed from the mounting bracket 31.

The study desk of FIG. 1 is used in the same way as a conventional study desk with a shelf and a lighting unit, and is convenient and easy to use, especially for children in lower grades. Furthermore, in the study desk with shelves shown in FIG. 1, the operation box 20 can be removed from the shelf 18 and moved to a location most convenient for the desk user.
