Description

[Detailed description of the invention] <<Industrial Application Field>> The present invention particularly relates to a learning chair for children used at home.

《Conventional technology and problems》 The above-mentioned conventional study chair has one seat part and one seat part.
Since the chair consists of two legs, it was necessary for a tutor, parent, sibling, etc. to prepare a separate chair (an auxiliary chair) when guiding the child's studies.

When the auxiliary chair is not in use, the chair used by the child is stored under the desk top, so the auxiliary chair is usually placed in a corner of the room, which takes up a lot of space in the room. This had the disadvantage of reducing the usable space.

<<Purpose and structure of the present invention>> The present invention has a simple structure and aims to improve the above-mentioned drawbacks. The legs of the chair are detachable, and an auxiliary chair is detachably attached to the underside of the seat of the chair.

"Example" Hereinafter, the present invention will be explained based on the drawings.

FIG. 1 shows an exploded perspective view of the main parts of the present invention, in which 1 is a seat body in which a backrest part 11 and a seat part 12 are integrally formed, and 2 is a seat body attached to the bottom surface of the seat part 12 at approximately the center thereof. A support cylinder 2 that holds a height adjustment shaft 22 whose upper end is connected to a support body 21 in a height-adjustable manner.
3, and a support leg 24 that is H-shaped in plan view, with the lower end of the support tube 23 connected to the upper surface of the central portion.

3, 3 are locking members attached to the lower surface of the left and right ends of the seat portion 12 in the same direction with a predetermined interval;
Reference numeral 5 designates an auxiliary chair that is locked to the locking members 3, 3.

As shown in FIG. 2, the locking member 3 is formed by bending a wire rod, and includes mounting parts 31, 31 with both ends crushed, and hanging parts 32, 32 with the mounting parts 31, 31 bent downward. Locking portions 33, 3 formed by bending the lower ends of the hanging portions 32, 32 upward into an arc shape
3 and a connecting portion 34 located between the locking portions 33.

By making the lengths of the front and rear hanging parts 32, 32 different depending on the longitudinal inclination of the lower surface of the seat part 12, the locking parts 33, 33 are always attached to the seat part 12.
It is attached to the lower surface in a horizontal state, and a space 30 for attaching and detaching the auxiliary chair 5 is formed between the continuous part 34 and the lower surface of the seat part 12.

The auxiliary chair 5 consists of a seat portion 51 and left and right leg portions 6, 6 attached to the back side of the left and right ends of the seat portion 51, and the left and right width of the seat portion 51 is approximately equal to the left and right width of the backrest portion 11. The height dimension of the leg portion 6 is configured to be shorter than the front and rear width dimension of the seat portion 12.

The leg portion 6 has a substantially U-shape in side view by bending a round pipe having an outer diameter approximately equal to the inner diameter of the locking portion 33 of the locking member 3, and has vertical rods 6 located at the front and rear.
1 and 61, and a floor contact rod 62, and the vertical rods 61 and 61 of the left and right legs 6 are on the lower surface of the seat 12,
It is moved laterally and is locked by the locking parts 33, 33 from the attachment/detachment spaces 30, 30. (Situation shown in FIG. 3) When removing the legs 6, 6 from the locking members 3, 3, first lift them upward and then move them laterally to remove them.

In this embodiment, the legs 6 of the auxiliary chair 5 are approximately U.
Although the chair is shaped like a letter, it may be of the so-called four-legged type, and the configuration of the locking member 3 can be changed as appropriate without departing from the gist of the present invention, and the auxiliary chair can also be used as an ottoman. Needless to say.

<<Effects>> The present invention has locking members attached to the underside of the seat at predetermined intervals, and the legs of the auxiliary chair can be freely connected to and detached from the locking members. It can be easily stored in the room, does not require a place for an auxiliary chair, and the room can be used effectively.
