In the infant seat, which can be used as a chair and in a state usable as a bed, the range from the back of the infant to the buttocks on the seat and the back is determined. The supporting part is formed in a double structure, a large number of air holes are formed in the infant side seating surface and the back surface of the double structure part, and air circulation ports are formed before and after the double structure part. It is characterized by that.

  According to a second aspect of the present invention, in the first aspect of the present invention, the seat portion is formed with a concave portion provided with an air circulation port in the front and rear, and the air hole is formed in the concave portion. The seat plate is detachably mounted.

  The invention according to claim 3 is the invention according to claim 1 or 2, wherein the infant seat is swingably supported by a support leg composed of a front leg and a rear leg, and the swing structure causes the inside of the double structure portion. It is characterized by facilitating the circulation of outside air.

  In the present invention, as described above, the seat portion and the back portion of the seat that support the range from the back of the infant to the buttocks are formed in a double structure, and the infant side seating surface and the back surface of the double structure portion are formed. Numerous air holes are formed, and air circulation ports are formed before and after the above-mentioned double structure portion, so that the sweat accumulated in the seat and back that are in close contact with the infant can be released, making it comfortable and hygienic Can be.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is a perspective view showing a schematic configuration of an infant chair, FIG. 2 is a side view thereof, and an infant seat 1 is supported by X-shaped legs 2 formed in a pair of left and right X shapes. The X-shaped leg 2 is constructed by pivotally attaching the middle part of the front leg 3 and the rear leg 4 to each other by a pin 5. The left and right front legs 3 are connected by a front connecting rod 6 a, and the left and right rear legs 4 are connected. Are connected by a rear connecting rod 6b (FIG. 2). The upper end portion of the rear leg 4 is pivotally attached to a boss 8 provided at the front portion of the seat support member 7, and the upper end portion of the front leg 3 is front and rear with respect to the seat support member 7 at the rear portion of the seat support member 7. It is pivotally attached to a hinge coupling portion 9 provided so as to be movable. The outer surface of the seat support member 7 is provided with a cover that covers the seat support member 7 and the upper portions of the bosses 8 and the hinge joints 9 as indicated by chain lines. The infant seat 1 is placed so as to be swingable back and forth.

  As shown in FIGS. 1 and 2, the infant seat 1 is provided on a seat 10 on which an infant mainly puts a buttocks, a back 11 disposed behind the seat 10, and above the back 11. The headrest 12 is composed of a step 13 provided in front of the seat portion 10, and the back portion 11 is raised as shown in FIG. 1 and can be used as a chair, and as shown in FIG. A reclining mechanism is provided so that the bed can be used as a bed. When the back part 11 is tilted so that it can be used as a bed, the step 13 also swings upward in response to the back swing of the back part 11 so that the infant's foot is supported. Side walls 13a are provided on both sides of the step 13, so that the baby can be prevented from falling during use as a bed as described above, and the visual anxiety that it may fall may be eliminated. It is.

  FIG. 4 is a view showing the structure of the connecting portion between the front leg 3 and the rear leg 4 and the seat support member 7. The upper end of the rear leg 4 is pivotally attached to the boss 8 of the seat support member 7 by a pin 14. The upper end of the hinge is pivotally attached to the hinge joint 9 by a pin 15. A slide bar 16 is integrally provided on the hinge coupling portion 9, and the slide bar 16 is accommodated in the seat support member 7 so as to be slidable in the front-rear direction. That is, the slide bar 16 is formed with a long hole 17 extending to the hinge coupling portion 9 in the front-rear direction, that is, in the longitudinal direction. Two pins 18 projecting from the sheet support member 7 at a predetermined interval are inserted into the long holes 17, and the slide bar 16 is moved in the longitudinal direction by the engagement between the long holes 17 and the pins 18. Are slidable. The slide bar 16 is urged by a spring (not shown) in the left direction in FIG. 4, that is, in the direction in which the X-leg 2 extends and becomes higher.

  The slide bar 16 has a quadrangular cross section, and a plurality of adjustment holes 19 are arranged in a row in the longitudinal direction on the upper surface of the slide bar 16. On the other hand, the seat support member 7 is provided with a pin 20 that is selectively inserted into one of the adjustment holes 19 so as to be movable up and down. The pin 20 is urged in the insertion direction by a spring 21, and a lever 22 is provided to be engaged with the enlarged diameter portion of the pin 20. The lever 22 protrudes outside the seat support member 7 and can move up and down along the pin 20.

  Thus, when the lever 22 is pulled upward from the outside of the seat support member 7, the pin 20 moves upward against the biasing force of the spring 21 and is removed from the adjustment hole 19. When the pin 20 is disengaged from the adjustment hole 19, the slide bar 16 is moved to the left in the figure by the action of a spring (not shown), thereby extending the X-shaped leg 2 hinged to intersect with the X-shape. The height of becomes higher.

  On the other hand, when the pin 20 is pulled out from the adjustment hole 19 and the seat support member 7 is pushed down in this state, the slide bar 16 moves to the right in FIG. 2 together with the hinge coupling portion 9 so that the inclination angles of the front legs 3 and the rear legs 4 are increased. When the hinge connecting portion 9 is moved to the rightmost position and the pin 20 is engaged with the adjustment hole 19, the folding state is lowered. This folded state is shown in FIG.

  Incidentally, a twin-wheel caster 24 is attached to the lower end portions of all front legs 3 and rear legs 4. Thus, the infant chair can be easily moved back and forth and right and left by the caster 24, the turning performance can be sufficiently improved, the small turn is effective, and the infant chair can be moved freely even in a narrow room.

  FIG. 6 is a longitudinal side view of the infant seat, in a state where the back part 11 is raised with respect to the seat part 10 and can be used as a chair, and as shown in FIG. It is attached so as to be tiltable by the shaft 25 so as to be in a state.

  The seat portion 10 is formed with a concave portion 26 in a portion mainly supporting an infant's buttocks, and a seat surface plate 28 provided with a number of air holes 27 is detachably attached to the concave portion 26. The bottom plate portion 26a of the recess 26 and the seating surface plate 28 form a double structure. An air circulation port 29 is formed in the front wall portion of the recess 26, and the rear portion of the recess 26 is released to the atmosphere. Further, air flow ports 28 a are also formed in the front wall portion and the rear wall portion of the seat plate 28. On the other hand, a number of air holes 30 are also formed in the lower part of the back part 11 at positions corresponding to the seating surface plate 28 of the seat part 10 when the back part 11 is in a tilted state.

  Thus, sweat from an infant sleeping on the seat 1 is formed by the recess 26 and the seat plate 28 through the air hole 30 of the back portion 11 and the air hole 27 of the seat plate 28 of the seat portion 10. There is no perspiration on the surface of the seat 10 that flows into the double structure and is in close contact with the infant, and comfort can be maintained. In addition, the sweat that has flowed into the double structure part is dissipated by the outside air flowing through the double structure part through the air circulation ports 29 and 28a formed in the front and rear wall parts of the double structure part, and is necessary. Accordingly, the seat plate 28 can be removed to clean the inside of the recess 26, which can be hygienic. Furthermore, especially in the case where the seat is swingable back and forth, the outside air is actively circulated in the double structure portion by the swing operation, and moisture such as sweat collected in the double structure portion is effective. The hygiene is improved.
