The upper locking pin is pulled up through the vertical groove, and the upper and lower locking pins are locked in the vertical groove, and the script body maintains this state without swinging.

[0009] Also, the script body portion is pulled downward against the elastic force of the elastic member, the upper and lower locking pins are moved downward along the vertical groove, and the upper locking pin is placed at one end of the horizontal groove. Then, by slightly swinging the script body around the lower locking pin, the upper locking pin enters into the horizontal groove, and by further swinging the script body, the upper and lower locking pins are removed. is in a state where it is locked in the horizontal groove, and the main body part is in a folded state.

[0010] That is, the script body is folded by the upper and lower locking pins that are guided in the horizontal and vertical grooves, and the screen is folded horizontally at the ends of the horizontal and vertical grooves or at the locking portions. The folded state of the script body can be maintained.

Furthermore, in order to change the script body from the folded state to the upright state, the script body is swung in the opposite direction, and the upper locking pin is inserted into the vertical groove from the horizontal groove. The upper locking pin moves upward in the vertical groove via the lower locking pin due to the elastic force of the member, and the upper and lower locking pins are locked in the vertical groove, so that the script body part is in an upright state.

That is, the center point of the folding rotation of the script body can be moved up and down so that it moves upwards most near the folded state, and if the script body is swung in the folding direction, the script body The rotational center point moves upward along the vertical groove, and the script body can be folded without a part of the base protruding downward from the base of the leg.

[0013] Therefore, in the folded state of the script body,

Next, a vertical groove is provided in the base of the leg, and
The legs for the platform kotatsu, which are provided with horizontal grooves in the vicinity of the vertical grooves and which are connected with the locking grooves, can be moved through the lower locking pins by the elastic force of the elastic member when the script body is in an upright state. The upper locking pin is pulled up, the upper locking pin is locked in the locking groove, the lower locking pin is locked in the vertical groove, and the script body maintains this state without swinging.

In other words, the upper and lower locking pins that are guided in the locking and vertical grooves fold the script body part, and at the ends of the locking and vertical grooves or the locking portions, the upper and lower locking pins are guided in the vertical grooves. The folded state of the script body can be maintained.

[0016] In order to bend the script body from the upright holding state to the folded state, the script body is pulled downward against the elastic force of the elastic member, and the script body is locked downward. By slightly swinging the pin as the center, allowing the upper locking pin to enter the horizontal groove from the locking groove, and further swinging the script body,
The script body is held in a state in which the lower locking pin is locked in the vertical groove and the upper locking pin is also locked in the horizontal groove, and is in a folded state.

[0017] In addition, in order to change the script body from the folded state to the upright state, the script body is swung in the opposite direction and the upper locking pin is inserted into the locking groove from the horizontal groove. The upper locking pin moves upward via the lower locking pin due to the elastic force of the generating member, and the script body section becomes an upright state.

That is, the center point of the folding rotation of the script body can be moved up and down so that it moves upwards most near the folded state, and if the script body is swung in the folding direction, the script body Since the center of rotation moves upward along the vertical groove, the script body can be folded without a part of the base protruding downward from the base of the leg.

Therefore, in the folded state of the script body,
Most or all of the script body portion fits within the vertical height dimension of the frame body.
