Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an infant chair. More specifically, the present invention relates to an infant chair in which the infant seat is provided at a higher position than the appropriate seat position for adults.

(Prior Art) A child's chair is known in which a seat is provided at a higher position than the seat of a chair normally used by an adult in order to allow an infant to sit at a table with an adult.

Conventionally, this type of infant chair has had a seat at a fixed height position, so that it has been discontinued for a short period of time. That is, the seat of a high chair is generally taped by a weaning infant along with an adult.

Because the chair was set at a height that would be attached to a chair, it could only be used for a few years as the child grew, and had to be discarded regardless of how damaged the chair was.

By the way, 1. Usually, the height of the seat of a chair used by adults is
When approaching objects that are at a height that is convenient for use as a step stool and are difficult to reach, such as putting items in and out of shelves set at high places, or installing electrical appliances mounted on the ceiling, When performing repair work, etc., it is common practice to use a nearby chair as a step stool.

However, when using the chair as a step stool, the seat on which the feet are placed is considerably higher than the floor, and care must be taken when getting on and off the seat. Particularly for children and elderly people, getting on and off the vehicle can be dangerous. On the other hand, the height of the seat is considerably lower than the ceiling, so simply using the seat as a step stool may not be enough to reach objects in high places, causing some inconvenience. .

(Technical problem to be solved by the invention) The present invention has been made in consideration of the above-mentioned circumstances, and it is possible to improve the use of infant chairs, which were conventionally used only for a short period of time, to be effective as chairs for a longer period of time. To provide a child's chair which can be used both as a step stool and when used as a step stool, making it easy to get on and off the step stool and allowing the child to climb up to a higher place. It is something to do.

(Means and effects for achieving the technical object) The present invention is based on an infant chair having an infant seat at a higher position than the seat of an adult chair. The seat part is provided so as to be able to rise and fall freely so that it can take an intermediate position lower than the high position, and an auxiliary seat part is arranged on the front side of the infant seat part, and the auxiliary seat part is moved to the intermediate position. and a lower position lower than this, and the infant seat part and the auxiliary seat part are arranged so that they are on the same plane and aligned with each other when they are respectively in the intermediate position. It is composed of

With this configuration, by setting the infant seat in a high position, it can be used as a conventional infant chair, and as the infant grows, the infant seat and auxiliary chair can be used as a child chair. By setting the child's seat part to an intermediate position, the chair can be continuously used as a chair equipped with a new seat part formed by the child's seat part and the auxiliary seat part.

In addition to its function as a chair, it can also be used as a step stool with two steps. That is, when the infant chair of the present invention is used as a step stool, the auxiliary seat serves as a lower step, and the infant seat serves as an upper step. In this case, since the infant seat can be set at a higher position than the seat of the adult chair, it can be used as a step to climb higher than the seat of the adult chair. In addition, the auxiliary seat, which serves as the lower tread, is positioned at a lower position closer to the floor, making it easier to get on and off the upper tread.
