Description

TECHNICAL FIELD [0001] The present invention relates to a detachable armpit support for protecting the back of a spine and preventing varicose veins in a spine.

The present invention relates to an armpit support, and more particularly, to a removable armpit support that can be conveniently attached to a support including a back of a chair to protect the back of the user's spine and prevent 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.

In general, the chair includes a seat portion on which the buttocks of the seated person are seated, a backrest portion to which the back portion of the seated person is closely attached, a support portion that supports 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.

In particular, the above-described prior art is inconvenient to use because it is complicated to install on a chair, and therefore, an improvement measure is required so that the chair can be conveniently installed and used.

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