BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a chair for protecting the back of a spine and for preventing varicose veins,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair, and more particularly, to a chair that protects the back of a spinal column of a seated person and prevents varicose veins.

Modern people have a lot of time to sit and sit on a chair for a long time. For example, modern people who sit in a chair for a long time, such as a car or other airplane, or sit in a chair for a long time in an office or a school, give a lot of pressure to the back of the spine for a long time. As a result, it causes a lot of diseases related to the spine or the back, and it feels fatigue.

Generally, the chair includes a seat portion on which the buttocks of the seated person are seated, a backrest portion on which the back portion of the seated person is brought into close contact, a support portion for supporting the seated portion and the backrest portion at a predetermined height from the ground, and an armrest portion on both sides of the backrest portion and the support portion So that the arm of the seated person can lean comfortably.

However, the conventional chair having such a structure is structured to support only the back of the seated person and the lower body, especially the buttocks, so that most of the body load of the seated person is concentrated on the waist.

Therefore, it is difficult to distribute the body load properly. As a result, the waist of the seated person is inflicted on the waist to cause the back disease. Especially, it is a negative factor that inhibits the growth and development of the child, A problem has occurred.

A prior art for solving such problems is disclosed in Korean Registered Utility Model No. 20-0390006 (Jul. 7, 2005) entitled " chair for underarm support. &Quot; This prior art is hinged to the sliding member to support the armpit of the occupant with an arm rest which is rotated at a predetermined angle horizontally with respect to the sliding member.

However, the above-described prior art has a disadvantage in that it is structurally unstable because the vertical frame and the horizontal frame supporting the underarm support are spaced from the floor when the user's load is applied to the underarm support and are supported by the connection member of the chair.

That is, when a load is applied to any one of the pair of arm rests, the horizontal frame may be easily broken, and there is a risk of a safety accident.

Korean Registered Utility Model No. 20-0390006 (Line 7) 2005. 07. 07.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a spine waist protection and a varicose vein prevention chair that can be used stably and conveniently and can effectively protect a user's waist and varicose veins.

According to an aspect of the present invention, there is provided a chair comprising: a chair body; A base frame provided on the chair body; A variable connection portion provided on the base frame; A post portion coupled to the variable connection portion; And a variable connection portion that is adjustable in a lateral direction of the chair main body on the base frame, and the post portion is adjustable in a longitudinal direction of the chair main body on the variable connection portion, Wherein the position adjustable in the vertical direction and the axillary support portion are adjustable in length in the post portion.

The base frame may be detachably coupled to both sides of the bottom surface of the chair body in the transverse direction.

The variable connection unit includes a variable connection frame having one side inserted into the coupling groove of the base frame and the other side coupled to a lower side of the post, and the variable connection frame is provided with a variable hole perpendicular to the coupling groove, The seat can be adjusted in the longitudinal direction of the chair body along the variable hole.

The variable connection frame of the region to be inserted into the coupling groove may be provided with a plurality of stopper balls inserted into the stopper groove provided in the coupling groove by the elastic force of the elastic body to fix the variable connection frame.

Wherein the post portion includes: a post load having a coupling rod penetrating the variable hole at a lower end thereof and the armpit supporting portion coupled to the upper portion; And a rod coupling member coupled to the coupling rod and fixing the post rod to the variable connection frame.

The outer circumferential surface of the coupling rod is threaded so that the rod coupling member can be screwed to the coupling rod.

The axle support portion includes: an axle support rod coupled to an upper portion of the post rod; An armpit support coupled to the axle support rod to support an axilla of a user; And a coupling member for coupling the axle support to the axle support rod, wherein the axle support rod is provided with a stopper gear, and a gear for engaging with the stopper gear is provided at a lower end of the axle support, The engagement of the gears maintains the axle supports in a rotated position and the base frames spaced apart from one another can be connected to each other by at least one reinforcing link.
