[0009]

FIG. 1 is a diagram showing a first embodiment of the present invention.
The infant chair 11 of this embodiment has a leg 12 formed of a box 12 having no cover plate. The box 12 is made in the usual way by fastening the bottom plate 14 and the four side walls 15a, 15b, 15c, 15d with screws or snaps. Rear wall 15 of box 12
d is higher than the other three side walls 15a, 15b, 15c, and is shaped to be used as a backrest. A seat plate 13 is openably and closably attached by two hinges 16 at approximately the center in the height direction of the rear side wall, and when the seat plate 13 is laid down, the upper side 1 of the three side walls except the rear side wall 15d of the box 1
It comes into contact with 7 and functions as a cover plate for the box 12. Seat plate 13
Has a slightly protruding end side from the front side wall 15a, and its upper portion is rounded. The front side wall 15a and the left and right side walls 15b, 15c of the box 12 have five through holes 20a, 20b, 20c composed of a set of circles, triangles and squares.
20d and 20e are provided, and a joining base 18 and a fitting hole 19 in the form of a short cylinder are provided at the four corners of the bottom surface 21 of the box 12, as shown in FIG.

The box 12 accommodates the through holes 20 and blocks 1a to 1f having a cross section having a slight play. As shown in FIG. 4, each of the blocks 1a to 1f has an edge surface 3 parallel to each other at opposite ends, and a fitting hole 4 extending in the direction perpendicular to the surface on substantially the same center of both edge surfaces. The blocks 1a to 1f are composed of a plurality of groups, and the plurality of groups are configured as a set of unit groups each including 3 or 4 blocks having the same face-to-face dimension S. In FIG. 4, three blocks of a circle, a triangle, and a square having the same face-to-face dimension S are taken as one unit, and blocks 1a, 1c, and 1e having the same height dimension for each shape and a block having a face-to-face dimension of half An example is shown in which a plurality of blocks are formed by a set of 1b, 1d, and 1f.

An infant opens the seat plate 13 and takes out the blocks 1a to 1f to play as a building block toy. When the play is over, the seat plate 13 is laid down and the blocks 1a to 1f are passed through the through holes 20 in the box 12. Put in. The triangular, square and round blocks can be inserted only through the triangular through holes 20b and 20d, the square through holes 20a and 20e and the round through hole 20c, respectively. Therefore, the infant has a block shape and a through hole shape. The child's ability to recognize the shape naturally increases.

When the baby does not play on the blocks 1a to 1f, the top plate 2 and the connecting rod 8 are prepared. The top plate has a joining base 5 having a joining surface 6 having a shape including the fore-edge shape of the blocks 1a to 1f on the bottom surface thereof, and the joining table 6 has the same diameter as the fitting hole 4 of the block in the center of the joining surface 6. A fitting hole 7 is provided. Here, the joining surface including the fore edge surface means a joining surface having a size such that the block does not project to the outside of the joining surface 6 when the fore edge surface 3 of the block is bonded to the joining surface 6. Specifically, as shown in FIG. 5, the shape of the joint surface of the top plate is preferably the same as the shape of the block. As shown in FIG. 6, the connecting rod 8 is a rod member fitted into the fitting holes 4 and 7 of the block and the joining base without a gap.

A connecting rod 8 is inserted into the fitting holes 4 of the blocks 1a to 1f to bond the small edge surfaces 3 to each other, and the small edge surface at one end thereof and the joining surface 6 of the top plate are fitted into the fitting holes 4 and 7 of both. The desk 10 having the leg 9 in which the blocks 1a to 1f are connected is assembled by fitting and joining the connecting rod 8. The height of the desk is set to a height commensurate with the infant chair of the present invention. Then, when the infant grows up, a block of the same face-to-face dimension is added to the lower end of the leg 9 of the desk to raise the height according to the growth of the infant. At this time, the joining base 1 on the bottom of the infant chair
Blocks 1a to 1f are also joined to 8 by connecting rods 8, and the height of the chair is adjusted to a height corresponding to the height of the desk. Thereby, the desk 10 and the chair 11 can be set to a height such that the infant is always in a correct posture.

FIG. 3 is a perspective view showing a second embodiment of the present invention. The chair according to the present embodiment is obtained by shortening the lateral length of the chair 11 according to the first embodiment, and the number of fitting holes in the front side wall 15a thereof is reduced from three to one. The major axis and the minor axis in the direction are almost the same. Since the number of the fitting holes is reduced, the number of options is reduced, and the infant can find the fitting holes corresponding to the blocks 1a to 1f more easily than the chair 11 of the first embodiment. In addition, the chair 11a itself does not get in the way because it does not take up space, and it is possible to make a chair of a size exactly suitable for one infant. The seat plate can be attached to the box by projecting locking pieces at the four corners of the bottom surface of the seat plate and dropping the locking pieces inside the side walls 15a, 15b, 15c, 15d.
