Description

Children's chair

The present invention relates to a child chair for children.

In order to facilitate children to eat on the chair, the existing children's chair usually has a dining table on the front side of the seat, and a food container is placed on the table to facilitate the child to take the food and drink.

Currently, there are two types of children's chair products having a dining table, such as a fixed table mechanism and a movable body. The child chair with a fixed table mechanism is fixed to the front side of the seat and fixed to the table. When a child wants to ride in a children's chair, the adult must pick up the child across the table to ride on the seat cushion. When the child wants to leave the child's chair, the adult must pick up the child across the table to leave the seat. It can be seen that the child chair can not change the shape of the child chair because the table is fixed on the front side of the seat, and has the problem of insufficient practicality. Because the table is fixed on the front side of the seat, the activity space of the child upper and lower chairs is too narrow. And there are inconveniences.

The movable child chair is constructed by the movable table mechanism, so that the movable child chair has the functions of changing the two types of the table, such as a dining table and no table, and the child chair having the fixed table cannot be used. The problem of insufficient practicality of the situational transformation. However, the movable dining table of the aforementioned known children's chair adopts a front and rear rotary collapsible mechanism. When using a movable dining table for a children's chair, based on the safety of use, the movable type must be used before the child rides on the children's chair. The dining table is turned forward from the rear side of the frame to the front side of the seat, and then the child can be placed on the seat of the child chair. At this time, the movable space is limited by the movable table on the front side of the seat. There are still problems that make it difficult for children to ride on children's chairs and to make it easier for children to come down from their children's chairs.

The purpose of the present invention is to provide a child chair that solves the problem that the existing child chair is not convenient for the child to ride in the child chair and the child is not convenient to descend from the child chair.

In order to achieve the foregoing objectives, the child chair set proposed by the present invention includes:  a chair frame, comprising a frame body, and a seat cushion disposed on the frame body, the frame body having a rod on each of the left and right sides of the seat cushion;  Two grab bars respectively connected to the two masts of the chair frame;  a rotary table mechanism capable of laterally rotating and clutching the front sections of the two handrails, the rotary table mechanism comprising a table, a rotating component and a connecting member, the rotating component being mounted on the side of the table The connecting member is disposed on the other side of the table. The table is respectively connected to the connecting rod by the rotating component, and the connecting member can be relatively separated from the correspondingly connected one of the grab bars. The table can be rotated and retracted laterally away from the front side of the seat cushion by the rotating assembly relative to a handrail bar of the seat frame.  

With the creation of the children's chair, it has at least the following characteristics:  1. Provide children with an unobstructed open space on the children's chair and the children leaving the children's chair: The new children's chair is constructed by a combination of a chair frame, two handrails and a rotating table mechanism, and the two handrails are respectively arranged on the chair. On the left and right sides of the frame, the rotary table mechanism is respectively provided with rotating components and connecting members on both sides of the table, and the rotating component and the connecting member are respectively connected with the two handrails, and the connecting members can be correspondingly separated by the handrails, so that the table is borrowed The front side of the seat cushion of the chair frame is laterally rotated by the rotating component relative to the corresponding handrail bar, so that the front of the seat frame is formed in an unobstructed open state, which is convenient for the child to ride on the child chair and facilitate the child to descend from the child chair.  2. It has good operation and convenience: during the use of the new children's chair, the user can directly rotate the rotary table mechanism and disengage the connecting member on the side of the table from the corresponding handrail bar, even if the table is rotated The component is laterally rotated away from the front side of the seat cushion of the seat frame relative to the corresponding handrail bar, so that the front of the seat frame is formed in an unobstructed open state. When combined, the user can also directly rotate the rotary table mechanism to reverse the connection, and the connecting member The re-attachment corresponding to the handrail bar enables the rotary table mechanism to be smoothly supported by the two handrails, so that the child chair has good operation simplicity.
