Abstract

In this nursery instrument, a selection plate (100) is fixed to a reinforcing plate (29) with a pin (110), to be slidable through a slot (125e). A through hole (125a, 125b, 125c) has the same bore diameter as an engaging hole (25a, 25b, 25c), and a through hole (125d) consists of a slot having a length substantially twice that of an engaging hole (25d) in a sliding direction. According to this mechanism, only a bed state can be selected up to a lapse of a constant time after birth of a baby. Thus, a nursery instrument capable of protecting respiration of the baby can be provided on the basis of medical criteria for the baby.

Claims

1. A nursery instrument capable of selectively functioning as an infant bed and as an infant seat, said nursery instrument comprising a seat portion and a backrest portion capable of assuming an upright seat position and an inclined bed position,

said nursery instrument further comprising locating means provided on said backrest portion for selectively positioning said backrest portion relative to said seat portion,

a first engaging portion provided on said seat portion for engaging with said locating means to form said infant bed, wherein said seat portion and said backrest portion are substantially flat,

a second engaging portion provided on said seat portion for engaging with said locating means to form said infant seat, wherein said backrest portion is in a substantially upright position,

an intermediate engaging portion provided on said seat portion for engaging with said locating means to attain an inclination in an intermediate stage between said infant bed and said infant seat, and

selection means for enabling only an engagement of said locating means with said first engaging portion to form said infant bed and for disabling an unintended engagement with said second engaging portion and said intermediate engaging portion until a change is positively intended, and wherein said locating means has an engaging member for selectively engaging with said first engaging portion, said second engaging portion and said intermediate engaging portion,

said first engaging portion, said second engaging portion and said intermediate engaging portion having a plurality of spaced holes, and wherein said selection means has a plate member sliding along said spaced holes for opening said first engaging portion, said second engaging portion and said intermediate engaging portion in a first position while opening said first engaging portion and closing said second engaging portion and said intermediate engaging portion on a second position.

2. A nursery instrument capable of selectively functioning as an infant bed and as an infant seat, said nursery instrument comprising a seat portion and a backrest portion capable of assuming an upright seat position and an inclined bed position,

an intermediate engaging portion provided on said seat portion for engaging with said locating means to attain an inclination in an intermediate stage between said infant bed and said infant seat, and

selection means for enabling only an engagement of said locating means with said first and second engaging portions while disabling an engagement with said intermediate engaging portion, and wherein said locating means has an engaging member for selectively engaging with said first engaging portion, said second engaging portion and said intermediate engaging potion, wherein said first engaging portion, said second engaging portion and said intermediate engaging portion having a plurality of spaced holes, and wherein said selection means has a plate member sliding along said spaced holes for opening said first engaging portion, said second engaging portion and said intermediate engaging portion in a first position, while opening said first engaging portion and said second engaging portion and closing said intermediate engaging portion on a second position.

3. The nursery instrument of claim 2, wherein said second engaging portion is located in a position separated from said locating means more than said first engaging portion and said second portion, and wherein said locating means has an engaging member adjustable in its projection length for engaging with said first engaging portion and said second engaging portion while not engaging with said intermediate engaging portion.
