[0045]

As described above, as can be seen from the specific examples shown in the embodiments, the wooden study desk / chair of the present invention allows the legs and the deck or the seat plate to slide freely up and down. It is a structure that is combined to form a desk or chair. Even if it is made entirely of wood, it can be used for many years, and it can be provided as a relatively inexpensive thing. All parts are made of natural wood that is relatively inexpensive such as cedar and hiba wood, and each joint does not use any metal fittings at all. It is realized as a strong joint, especially for the legs of the legs that need strength, the deck of the leg or the short leg of the seat plate, with wide and thick side wheels or attached wheels. By doing so, the strength of the joint is assured more reliably

A structure in which the combination of the deck portion or the seat plate portion with respect to the leg portion can be slid up and down in accordance with the height change of the same person that changes depending on the height of the individual or the growth of the individual. However, since the load is concentrated on the picking surfaces of both, the risk of wear and breakage is extremely high during use, it is extremely high. In the rear leg inner side upper end predetermined range portion, and in the front-rear center part of the side wheel outer surface,
In the part through which the fixing screw for dual purpose of positioning is inserted, and in the deck part or the seat plate part, the short leg front leg and the rear leg corresponding to the leg part, the upper end predetermined range part, and the attachment base High-end natural wood, such as zelkova, which is expensive but robust and reliable, is limited to the limited part, such as the part for screwing the hanging / fixing screw for positioning, in the center part in the front-rear direction of the wheel outer surface. A female board with hardwood grooves, a support board with hardwood through holes, a male board with hardwood ridges, and a hardwood adjustment screw hole so that the material is limited and the strength of the cedar wood etc. is reinforced. By adopting a structure in which the attached receiving plate is limited to the above-described specific portion, and is embedded and integrated, a special structure capable of adjusting the height is adopted. Desks and chairs are height-adjusting machines Not only is it not inferior to the usual ordinary wooden study desks and chairs that have not been adopted at all, but it has strength, durability and safety enough to surpass it, and of course, in terms of manufacturability, It is possible to provide the service efficiently without causing any disadvantage in terms of the unit price.

In particular, according to the structure described in the embodiment, the above-described operation and effect can be surely exhibited, and the appearance is extremely excellent. The leg portion and the deck or seat plate can have a safe structure that does not easily separate or separate during height adjustment or mischief, etc., and is not shown. However, the adjustment through holes 23b, 23b, ...
, Or 63b, 23b,..., That is, 30 mm in the adjustment through hole 23b in this embodiment.
In b, the positions of the lower ends of the front short leg and the rear short leg of the deck 2 or the seat plate 6 are preliminarily provided as marks on the side surfaces of the front leg and the rear leg of the leg 1 or 5 in accordance with the interval of 20 mm. 20 × 3 which can measure 20mm and 30mm
A special square ruler having a cross section of 0 mm is prepared, and the mark is used as a guide, or the square ruler is used to hold the exact height of the deck 2 or the seat plate 6 with respect to the leg 1 or 5 while maintaining the height. The male screw portion 31 or 71 of the hanging / fixing screw 3 or 7 can be easily and reliably used by any one of the receiving holes 23a or 63a of the deck 2 or the seat plate 6 with the hard wood adjusting screw holes. It can also be screwed into 23b or 63b to make it temporarily fixed.

Furthermore, if a sleeve plate and a drawer plate as shown in FIGS. 7 and 9 are separately prepared and can be combined, a lesson using a personal computer which is no longer required in the compulsory education process can be performed. The wooden study desk / chair of this invention that I usually use is a desk for personal computers.
In addition to being fully usable as a chair, if you use this wooden study desk / chair as a specific individual from the beginning of enrollment, and adopt a system at school when you graduate, you can take it back to your home as it is It is possible to use in the optimal condition according to the growth of a specific individual, and not only will you be able to receive employees in the correct position at any time, but also it will be handled exclusively because it will be exclusively for specific individuals Even if the temporary deck 25 becomes dirty or scratched, it has the advantage that it can be easily regenerated and used as a new smooth deck 25 by shaving its surface because it is made of wood. In addition, even after being brought home, it is not only important to treat it as an accessory that has been worn for many years and is attached to it, but also as a dedicated desk and chair for personal computers. Since the functions can be continued as it is used to combine enough, the final period of until the disposal will be very long, big effect also will be demonstrated that also lead to the effective use of much wood resources.

As described above, the wooden study desk / chair of the present invention, and the sleeve plate and drawer plate combined therewith can be used to improve the texture of the traditional teal desk / chair while reconsidering the educational environment of children. It has been reported that children are also adversely affected, and it has features that can reliably cope with the creation of an environment that uses abundant wood, which is a natural material that can be used in place of it. In addition to gender, it has realized a new wooden study desk / chair that has the extremely excellent advantage of being able to respond appropriately to the growth of specific individuals, so it has received high praise from various fields, It is expected to be widely used and used.
