Μ 日 士, but when the rod 22 is stretched upward by the outside of the bed and chair support member 7, the pin moves upward against the potential energy of the spring 21, and disengages from the adjustment. The pin 2G is released from the adjustment hole 19 and slides The lever 16 is moved leftward in the figure by the action of a non-illustrated bullet ^, whereby the X-shaped tripod 2 which crosses in a X shape and is extended by the hinge name 5 will increase the height of the chair. 2〇: = On the one hand, in this state, when the pin 20 is pulled out from the adjustment hole 19 and the support member 7 is pressed down, the slide rod 16 and the hinge joint 9 will move together to the right in FIG. 2 In addition, the inclination angle of the front tripod 3 and the rear tripod 4 will change to the far right, and the pin 20 and the adjustment hole card σ 0 guard will be in a folded state with a low height. Figure 5 shows the state of the stack. 200536499 In addition, double lower wheels casters 24 are installed at the lower ends of all the front legs 3 and the rear legs 4, respectively. Therefore, with the aforementioned casters 24, the infant chair can easily move forward, backward, left, and right, and can fully improve the rotation, which is conducive to small-scale rotation, and can move freely even in a narrow room. 5 FIG. 6 is a longitudinal sectional side view of the aforementioned infant bed and chair 1. The back n is pivoted around the shaft 25 in a tiltable manner and is held by the reclining mechanism na, so that it can stand upright against the seat. The state of being used as a chair and the state of being used as a bed as shown in FIG. ® The seat portion 10 has a first double structure body 32a. The first double structure body 1032a is composed of a seat panel 28 provided with a large number of air holes 27 and a first bottom plate 26a. The back portion 11 also has a second The double structure body 32b is composed of a back plate 30a provided with a plurality of air holes 30, and a second bottom plate 30b. The first double structure 32a extends to the range of the child's buttocks, and the second double structure 32b extends to the range of the child's back. 15 In this plastic state, the first double structure 32a and the second double structure 32b are formed by a recessed portion 26 provided on a portion corresponding to the buttocks of the infant, and a seat panel 28a and a back plate 30a disposed on the #recessed portion 26. Since the dual structure constituting one body is formed, the internal systems of the first dual structure 32a and the second dual structure 32b communicate with each other. 20 At this time, the bottom plate of the recessed portion 26 is constituted by the first bottom plate 26a of the first double structure 32a and the second bottom plate 30b of the second double reconstructed body 32b. Of course, the first double structure 32a and the second double structure 32b may be different structures. As mentioned above, the recess 11 is mainly formed in the part for supporting the buttocks of young children. 200536499 Section 26. The seat panel 28 which is provided with a large number of air holes 27 is detachably mounted on the recess 26. The first bottom of the recess 26 is 26a and the seat panel 28 constitute a first double structure body 32a. In addition, an air circulation opening 29 is formed in the wall portion in front of the recessed portion 26, and the rear portion of 5 of the recessed portion 26 is liberated in the atmosphere. The front and rear portions of the recessed portion 26 are respectively formed with air circulation ports 28a. On the other hand, the back plate 30a of the second structure 32b of the back 11 is also provided with a large number of air holes 30. When the back 11 is inverted, the air holes 28 of the seat panel 28 of the seat 10 and the back plate 30b The air holes 30 are arranged side by side in a roughly horizontal direction and in a 10 direction. In addition, the sweat generated by the child lying on the bed and chair 1 flows through the air holes 30 of the back plate 30a of the back 11 and the air holes 27 of the seat panel 28 of the seat 10, and flows into the recess 26 and the seat. Inside the first and second double structures 32a, 32b formed by the face plate 28 and the back plate 30. Therefore, sweat does not accumulate on the surface of the seat portion 10 and the back portion 11 that are in close contact with the infant, and the comfort can be maintained. The sweat flowing into the first and second dual structures 32a and 32b passes through the air circulation ports 29 and 28a formed in the front and rear portions of the recessed portion 26, and flows through the first and second dual structures 32a and 32bR. Emitted from circulation. In addition, the seat panel 28 can be removed from the cleaning recess 26 if necessary, and the hygiene of the infant bed 1 can be maintained. In addition, especially when the bed and chair 1 are supported by the X-shaped footrest 2 that can be swung back and forth, the outside air can actively circulate in the first and second double structures 32a and 32b by the aforementioned swing action, which is effective The sweat and other water accumulated in the first and second double structures 32a and 32b are dispersed to improve hygiene. 12 200536499 LSchematic description 3 # The first figure is a perspective view of the infant chair of the present invention. -Figure 2 is a side view of the toddler chair of the present invention.
