  Next, the leg 6 will be described. As shown in FIGS. 2 and 5, the four legs 6 have a circular horizontal cross-sectional shape, one end of which is in contact with the floor and the other end on the bottom surface of the seat portion 5 as described above. It is in contact with the four corners of the provided recess 5d. Further, the leg 6 is provided with at least one groove 6a so that a horizontal rod 7 described later can be inserted. In the present invention, the horizontal rod 7 is fixed by inserting it into the groove 6a provided in the leg 6. However, the fixing method of the leg 6 and the horizontal rod 7 is not limited to this, and for example, the horizontal rod 7 is fixed to the groove 6a. Before the 7 is fitted, the adhesive can be applied to the groove 6a in advance so that it can be firmly fixed. Further, the horizontal rod 7 and the leg 6 may be fixed using a fixing means such as a screw or a nail. As in the present invention, fixing without using fixing means does not impair the aesthetic appearance. Further, the number of parts can be reduced, and the strength can be kept high. The legs 6 are connected in a staggered fashion by means of horizontal rods 7, which intersect at least at one location and are pivotally supported at an intersection 8 so as to be pivotable.

  In addition, as FIG. 2 shows, the cap part 9 can be provided in the floor and the end which installs the leg 6 so that a floor may not be damaged.

  Further, for the leg 6, various kinds of wood represented by hiba material can be used.

  As shown in FIGS. 2, 4, and 5, the horizontal rod 7 is a portion that connects the four legs 6 alternately as described above, and the horizontal rod 7 intersects at least at one place. , And is pivotally supported at the intersection 8 so as to be turnable. At the intersection 8, it is fixed via bolts 8a, nuts 8b, and spacers (in the present invention, washer 8c). By using the spacers, smooth opening and closing is possible, and the horizontal rod 7 is damaged when opening and closing. There is no. In particular, in the case of a Buddhist chair, the surface of the chair may be painted with lacquer or the like, and it is very important to prevent scratches through a spacer. In addition, it is preferable that the spacer is installed between two horizontal rods 7 that cross each other in addition to the upper and lower sides of the horizontal rod 7, thereby enabling a smooth opening and closing and damaging the horizontal rod 7 during opening and closing. There is no.

  Note that various kinds of wood typified by hiba can be used for the horizontal basket 7.

  As shown in FIGS. 2, 5, and 6, after the horizontal ridge 7 is opened at a right angle at the intersection point 8, four recesses 5 d provided on the bottom surface of the seat portion 5 are provided in four directions. It fits so that each end of each leg 6 may contact.

  In the present invention, the case where there are two pairs of crossed horizontal rods 7 will be described. However, in the present invention, the number of crossed horizontal rods 7 is not particularly limited, and may be one pair or plural. This is because, in the case of the conventional simple assembly chair 1 as shown in FIG. 1 described above, when the user sits down, all the weights of the user are at the intersection 2b of the horizontal rod 2a (however, not shown horizontally in FIG. However, in the case of the present invention, the horizontal rod 7 connects the legs 6 in a staggered manner, and the opening / closing mechanism of the legs 6 This is because a load is not applied because the purpose is to form one end.

Embodiment 2
If the seat 5 and the legs 6 (and the horizontal rod 7) of Embodiment 1 are removed and then stored in the recess 5d provided on the bottom surface of the seat 5, a further space saving can be realized. . As shown in FIGS. 7A to 7C, the chair 10 according to the second embodiment is provided with a leg 6 (the part that is actually stored is horizontal) by providing a cut 5g in the frame tree 5a of the seat 5. A part of the ridge 7 is fitted in the seat portion 5 and can be stored.

  As shown in FIG. 7A, the horizontal rod 7 is accommodated by fitting into a notch 5 g provided in the frame tree 5 a of the seat plate 5. Further, as shown in FIG. 7B, a fixing member 5h is provided so that the fitted horizontal rod 7 is not easily removed. Various buttons such as a snap button can be used as the fixing member 5h.

  In addition, as shown in FIG. 7B and FIG. 7C, the case where the notch 5g is provided with a step so that the two horizontal rods 7 are in close contact with the frame tree 5a when stored is described. However, the cut 5g of the present invention is not limited to such a shape, and may be provided so as to be simply rectangular in a side view. Further, in the case where the horizontal width of the horizontal rod 7 and the horizontal width of the notch 5g are the same or slightly smaller than the horizontal width of the notch 5g, the horizontal width of the notch 5g can be reduced by fitting, so that it can be fixed without the fixing member 5h. .

  Further, the surface of the cut 5g can be covered with an elastic material such as rubber or an impact absorbing member so that the frame tree 5a and the horizontal rod 7 are not damaged when fitted.

Embodiment 3
By shortening the lengths of the legs 6 and the horizontal rods 7, the legs 6 and the horizontal rods 7 can be completely stored in the recesses 5d on the bottom surface of the seat portion 5, and the maximum space saving can be realized. The chair 11 according to the third embodiment is configured such that the lengths of the legs 6 and the horizontal rod 7 are shortened and can be completely stored in the recess 5 d provided on the bottom surface of the seat portion 5. When the length of the horizontal rod 7 is shortened, when the legs 6 are opened through the intersection 8, the four legs 6 do not reach the four sides of the recess 5d provided on the bottom surface of the seat portion 5. Therefore, as shown in FIGS. 8A to 8D, even when the contact frame 5i is further provided in the recess 5d provided on the bottom surface of the seat portion 5 and the horizontal rod 7 is short, It can come into contact with the seat 5. The height of the abutting frame 5i is generally sufficient to be 1 cm. If the height is too low, the abutting is unstable, and there is a risk that the leg 6 may come off the abutting frame 5i due to a sudden external force. If the height is too high, it may come into contact with the horizontal basket 7 when stored and may not be stored completely.

Embodiment 4
The chair 12 of the fourth embodiment has a recess 5d provided on the bottom surface of the seat portion 5 as shown in FIGS. 10A and 10B instead of the contact frame 5i provided in the third embodiment. In addition, a fitting portion 5j is provided so that the four legs 6 can be fitted. In general, the depth of the fitting portion 5j is sufficient if it is 1 cm. If the depth is too shallow, the fixing is insufficient, and there is a risk that the leg 6 may come off from the fitting portion 5j due to a sudden external force. When too much, the intensity | strength of the baseplate 5b of the seat part 5 may fall.

  As described above, the chair of the present embodiment includes a seat portion and four legs extending in the vertical direction, and the seat portion can be fitted into one end of the four legs, and the four The seat is placed on one end of each leg, and alternately connected by at least one pair of horizontal rods, and the at least one pair of horizontal rods are pivotally supported so as to be pivotable with respect to each other. Therefore, when the user sits down, the legs are long enough not to put a burden on the knees, and the seat is horizontal with respect to the installation surface, so the posture when sitting is stable and It is possible to provide a folding assembly chair for Buddhism that has no burden, is easy to store and install, has high strength, and has a small number of parts. Further, the protective cap provided at one end of the leg does not damage the installation surface, and further, the material constituting the chair is not damaged by the spacer provided at the shaft support portion. In addition, the legs can be stored in the seat, and space saving can be realized during storage.

  In addition, although this invention demonstrated the case where a seat part was square by the top view, the shape of a seat part is not limited to this. For example, in the case of adopting a rectangular seat in Embodiment 3, when storing along the long side of the recess provided in the bottom surface of the seat, it is completely stored without shortening the leg length. Possible. This is because it is only necessary to shorten the length of the horizontal basket in order to completely store the seat by making the shape of the seat rectangular. Similarly to this, even when only the leg length is shortened without changing the length of the horizontal rod, it can be completely stored. In this case, it is not necessary to newly provide a contact frame, but since it becomes a chair with a low height, it should be noted that it may not be suitable for practical use.

  The chair of the present invention is not particularly limited, but can be used as a chair for elderly people and children who are difficult to sit for a long time in Buddhism.
