Claims

[Scope of Claim for Utility Model Registration] 1. A baby chair in which the chair body consists of a backrest and a seat, and a handrail is arranged to surround the front from the back at armrest height, wherein the handrail is , a pair of handrail halves are divided symmetrically at the center of the front end, and each of the handrail halves has a pair of rotating arms pivoted on a base plate so as to rotate symmetrically. The handrail halves are fixed to the front end so that the front end parts of the handrail halves come into contact with or come close to each other at the center of the front end, and are in a closed state, and each handrail half is almost entirely stored within the chair body. The handrail is opened so that the handrail is in an open state, and the rotating movement of the handrail half is biased in the opening direction, and the handrail half is provided with a locking means for keeping the handrail in the closed state. A baby chair that is characterized by: 2. The baby chair according to claim 1, wherein the rotational movement of the handrail halves is biased in the opening direction by tilting the base plate backward and downward. 3. The baby chair according to claim 1 or 2,
The locking means includes a pair of locking pins formed symmetrically on each of the rotating arms, and a rotating locking plate disposed on the base plate and having a pair of locking holes into which the handrail is fitted when the handrail is in the closed state. The rotating lock plate can be rotated from the locked position to the unlocked position by a lock release lever integrally formed in the front, and can be returned to the locked position by the force of a spring. , A baby chair featuring:
