Description

Parish chair {STUDENT CHAIR}

The present invention relates to a chair for parish, and more particularly, to a chair for a parish that has a beautiful appearance and is practical because the fastening means does not protrude from the upper surface of the seat plate used mainly in schools and academies.

In general, as a chair for teaching tools that are mainly used in schools or academies, as shown in FIG. 1, it is widely used to fix a wooden or plastic seat plate or a backrest plate to a chair frame made of a metal pipe. In such a chair, it is fixed by bolting or riveting treatment to the chair frame on the upper surface of the seat plate or the backrest plate.

In these existing teaching aid chairs, since the fastening means such as bolts are exposed on the backrest plate or the seat plate surface, when students sit or stand up, the body and clothes may be damaged or torn by the fastening means bolts or the heads of rivets. It occurs frequently, and there is a problem that it is easily damaged due to sticking, tights, and the like.

Domestic Utility Model Registration No.0259415, as shown in Figure 2, to prevent damage to the body and clothes by the head of the bolt of the seat plate of the chair, a cover formed with a non-slip portion on the surface of the backrest and seat plate. The student's chair is disclosed to minimize the pain of the body part in contact with the back and buttocks by covering it. However, such a conventional chair is uneconomical because the cover must be separately manufactured, and the cover is not well fixed to the chair by the vigorous movement of the students, and there is a problem that it is peeled off or damaged, and thus there is a disadvantage of lack of practicality.

Domestic Utility Model Registration No. 0306644 discloses a device for fixing the seat plate of a student's chair, which is configured so that the seat plate can be fixed with only a simple fitting operation without fastening bolts.
