DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a general chair.

[0002]

2. Description of the Related Art Conventionally, there have been no general chairs except for dental chairs with lighting equipment.

[0003]

Conventionally, there is no general chair provided with a lighting device except for a dental chair because of the concept that a chair sits down and a desk reads a book using the lighting device. . Therefore, the potential effects of the following chairs were overlooked. B. The upper left side of the chair rear leg is the best position for the right handwritten person as the position of the illumination light source. This is a position where the amount of reflected light entering the eye can be reduced and a position at the time of writing can be illuminated. In the case of a person who writes by hand on the left, the upper right side of the rear leg is the ideal illumination light source position. B. If the chair has a removable table and a removable lighting device, you can easily move the chair and set up a comfortable lighting environment without any desk wherever you want. C. You can use a chair instead of a desk lamp.
SUMMARY OF THE INVENTION The present invention provides a reading chair provided with a retractable table and a retractable lighting device, which can be easily carried and installed, and can be used for reading and manual work without a desk and always under appropriate lighting with reduced eye strain. Is what you do.

[0004]

In order to solve the above problems, the present invention has the following arrangement. A chair comprising a leg (1), a seat (3), a backrest (6), and an armrest (4); a storage square tube part (7a) attached to a rear leg (1b) of the chair; (7a) a slide-in / out-type lighting fixture (7) comprising a sliding support (7b) which slides up and down in and out of the interior;
A table support shaft (5) is provided on the upper front of the left armrest (4) of the chair.
b) A table plate (5
a) and the left and right receiving portions (5f, 5f) supporting the table plate (5a) by horizontally sliding back and forth in front of and behind the armrest (4).
g) a chair with a removable table (5).

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
10 and its specific structure will be described. The chair is generally a common form of chair, preferably light. The leg (1) is composed of two front legs (1a), two rear legs (1b) and a reinforcing member (2). The seat (3) is a cushion (3b) stretched on a seat plate (3a) horizontally supported by four legs (1) and a reinforcing member (2). The backrest portion (6) is an S-shape having a lower end connected to the backrest frame (6a) extending from the two rear legs (1b) and the seat plate (3a) and an upper end connected to the backrest frame (6a). It consists of a back and back support plate (6b) bent in a shape. The retractable lighting device (7) has a storage square tube (7a) attached to the left rear leg (1b) of the chair with screws using an attachment member (71). In the case of a person who has left handwriting, it may be attached to the right rear leg (1b). Storage square tube (7
a), a sliding column (7b) sliding up and down therein, a swivel table (7d) and a tilting table (7e) fitted to the top of the head.
And a fluorescent tube mounting portion (7f).
g) is an example. The umbrella (7h) is of a semi-cylindrical shape, has a reflective surface on the inner surface, and can rotate around the fluorescent lamp (7g) tube. The rotation angle can be adjusted to change the illumination direction of the fluorescent lamp (7g). The removable table (5) suspends the table plate (5a) rotatably on a table support shaft (5b) outside a left receiving portion (5f) that slides forward and backward in front of a left armrest (4a). It is a structure to store it down. The sliding structure of the left receiving portion (5f) is such that a sliding inner tube (4c) in which a sliding outer tube (5e) inside the left receiving portion (5f) is connected and fixed to an armrest (4a) is used as a guide shaft. Slide on it. The table plate (5a) is rotatably supported by a table support shaft (5b) and a table support (5c) at the upper end of the left receiving portion (5f), and is rotated vertically 270 degrees from the vertically stored state to the outer circumference to the horizontal so that the right armrest is provided. It is used as a table, for example, for reading over a book by placing it horizontally over a right receiving part (5g) in front of the part (4a). The right receiving part (5g) of the right armrest (4a) that receives the right end of the table plate (5a) is also configured to slide back and forth.

[0006] How to put in and out the lighting fixture (7) and how to use it will be described with reference to FIGS. At the time of use, the stopper (7m) is removed, the on / off ring (7c) of the sliding column (7b) is turned to the off position of V, the sliding column (7b) is pulled out, and the on / off ring (7c) is at a desired height. U
To the ON position, the pin (7p) is fitted into the pin hole (7r) to fix the height position, and the umbrella (7h) is used to fix the fluorescent lamp mounting part (7f) of the tilting base part (7e). Tilt to the desired angle of inclination. Next, the swivel unit (7d) is turned to turn the fluorescent lamp (7d).
g) in the desired direction, and turn the umbrella (7h) so that the reflected light on the reading surface does not directly hit the eyes. That is, the height, the inclination angle, the inclination direction, and the irradiation direction of the fluorescent lamp (7 g) are adjusted and used. The use state is shown in FIGS.
When storing, on / off ring (7c)
, The sliding support (7b) is stored in the storage rectangular tube (7a), the umbrella (7h) is gripped, the fluorescent lamp (7g) is turned upside down, the irradiation front is turned to the chair side, and the umbrella ( 7h), store it so as to cover the fluorescent lamp (7g), and fix it with a stopper (7m) so as not to move.

In use, the left armrest (4) has the table plate (5a) and the right receiving part (5g) housed in the front outside and is used from the armrest (4a) as shown by Y in FIG. Then, lift the table board (5a) lower end with your left hand, lift it up slightly, support the upper surface of the table board (5a) with your left finger pad, and support the table board (5a) around the table support shaft (5b). While rotating, push up to the vertical state and attach it with your right hand and rotate it while tilting it further to the right to rotate the other end of the table plate (5a) to the right armrest (4a) as shown in FIG.
It can be used if it is placed on the right receiving part (5g) of the above and horizontally hung. Then, a book or the like is opened on the upper surface of the table board (5a) of the putting-in / out table (5), and manual work such as reading and writing is performed in a comfortable lighting environment using the above-mentioned putting-in / out lighting device (7). Can be. Figure 1 shows the height of the table surface
And the left and right receiving portions (5f, 5g) of the two-plate structure shown in FIG.
If the left and right armrests (4a) are adjusted in advance with height adjustment position change bolt holes (4a4, 5f4, 5g4) and position change bolts (4a3, 5f3, 5g3), then the height can be adjusted. It can be used by extruding. When not in use or when moving from place to place, the table board (5a)
Is returned to the left armrest (4) and stored, and the fixture (5d) is engaged so as not to move. The chair is compact when it contains both the removable lighting device (7) and the removable table (5), and can be carried like ordinary chairs.

[0008]

As described above, the present invention is a portable lighting device which can be easily carried and installed in a favorite place, and can be used for reading and manual work with less eyestrain under proper lighting even without a desk. 7) and a chair with a removable table (5). In particular, it is a useful device for fostering children's reading habits and preventing visual acuity deterioration, because the environment of lighting, tables and chairs that are easy to read for children in their infancy can be easily created anywhere within the reach of their parents. You can also move the chair and use it instead of a desk lamp.
