Abstract

The present invention is a seat portion on which the user is seated; a leg portion provided under the seat portion and in close contact with the ground; a frame portion including a support end seated on the upper portion of the leg portion to support the seat portion at a lower portion, and a vertical end bent upward from one end of the support end to stand adjacent to the back of a user seated on the seat portion; And it is installed movably up and down on the vertical end and provides a stretching chair including a support for supporting the user's ischial bone, thoracic vertebrae and sacrum when the user is seated on the seat portion.
Therefore, when the user is seated on the seat, the support part supports the user's sacrum and thoracic spine, so that the user sitting on the seat can maintain a correct posture, and as the support part moves up and down from the vertical end of the frame part, the user's height In response, the position of the support can be changed, and the user can easily stretch the thoracic vertebrae and chest by bending the user's waist while the support is in close contact with the thoracic vertebrae.

Description

Stretching chair

The present invention relates to a stretching chair, and more particularly, an operation of directly supporting the sacrum of a user seated in a seat portion to naturally erect the waist (lumbar spine) while maintaining the user's correct posture and allowing the user to tilt the thoracic spine back It relates to a stretching chair that can easily stretch the thoracic spine and chest at the same time.

Referring to the background technology described in Korean Patent Registration No. 10-1658486, students and office workers spend a lot of time sitting in chairs. It is clear that the longer the time, the worse it will be for health, and there are many cases where there is no time to exercise. In order to minimize various adverse physical effects caused by maintaining a fixed posture for a long time, stretching exercises that can be performed on a chair are being developed and distributed.

However, since there are many restrictions on exercise, a chair for enhancing the effect of stretching exercise by providing a chair with a special function has also been proposed.

For example, Korean Patent Application No. 10-2011-0028835 provides a stretching chair that enables the user to perform efficient stretching and back exercises in a sitting position during long work hours by enabling the seat plate and the backrest to rotate separately horizontally and have. However, this cannot be performed by limiting the stretching exercise to the motion of rotating the waist, and there is a problem in that it cannot respond to the body structure such as the user's sitting height.

The present invention was created to solve the above problems, and the support part supports the thoracic vertebrae and sacrum of the user seated on the seat part so that the user seated on the seat part can maintain a correct posture, and the support part supports the user's thoracic vertebrae An object of the present invention is to provide a stretching chair that allows the user to simultaneously stretch the thoracic spine and chest area with a simple motion of bending the waist when supporting the body.

In order to achieve the above object, the present invention is a seat portion on which the user is seated; a leg portion provided under the seat portion and in close contact with the ground; a frame portion including a support end seated on the upper portion of the leg portion to support the seat portion at a lower portion, and a vertical end bent upward from one end of the support end and standing adjacent to the back of a user seated on the seat portion; And it is installed movably up and down on the vertical end and provides a stretching chair including a support for supporting the user's thoracic spine and sacrum when the user is seated on the seat portion.

In the stretching chair according to the present invention, the leg portion is provided to be spaced apart from the first transverse end and the second transverse end, and the first longitudinal end and the second transverse end are provided vertically above the first transverse end and the second transverse end. It may include a vertical end, a first guide end connecting the first and second horizontal ends provided to be spaced apart, and a second guide end connecting the first vertical end and the second vertical end provided to be spaced apart. In addition, the upper surface of the second guide end may be formed in a seating groove in which the supporting end of the frame unit is seated.

The support end may include a first support end and a second support end provided to be spaced apart to support one lower surface and the other lower surface of the seat portion, and the vertical end may include the first support end and the second support end to be spaced apart from each other. The support end may include a first vertical end and a second vertical end provided to be bent at one end, and the frame portion may further include a connecting end connecting the first vertical end and the second vertical end provided to be spaced apart. have.

The support part moves up and down in the upper part of the vertical end and supports the thoracic spine of the user seated in the seat part, and the sacrum of the user seated in the seat part while moving up and down in the lower part of the vertical end. It may include a lower support for supporting.

The upper support portion includes an upper moving end that moves up and down from the vertical end, an upper intermittent means provided on a side surface of the upper moving end to be in close contact with the vertical end and intermittently controlling the vertical movement of the upper moving end, and the upper moving end may include an upper contact end that is provided to protrude toward the seat portion from one side of the seat portion and is in close contact with the thoracic spine of a user seated in the seat portion, and the upper contact end may have a rounded shape, and protrude outward may be in close contact with the user's thoracic spine.

The lower support portion includes a lower moving end moving up and down from the vertical end, a lower intermittent unit provided on a side surface of the lower support end in close contact with the vertical end and controlling the vertical movement of the lower moving end, and the lower moving end may include a lower contact end that is provided to protrude toward the seat portion from one side of the seat portion and is in close contact with the sacrum of a user seated in the seat portion, and the lower contact end may have a 'C' shape.

The stretching chair according to the present invention may further include a sensor unit provided in the seat part and the support part to measure whether the user is seated on the seat part and whether the support part is in close contact with the thoracic spine and sacrum bone of the user seated on the seat part have.

The seat part may include a seat plate provided on the upper part of the frame part, and a support protrusion provided to be spaced apart from the upper part of the seat plate and supporting the ischial bone of the user from the lower part when the user is seated on the seat plate, and is spaced apart from the seat plate A moving rail groove through which the support protrusion moves may be provided to adjust the separation distance of the support protrusion.

In the stretching chair according to the present invention, when the user is seated on the seat, the support part supports the user's sacrum and thoracic vertebrae so that the user sitting on the seat can maintain a correct posture, and the support part moves up and down at the vertical end of the frame part. Accordingly, the position of the support part can be changed in response to the height of the user, and the thoracic vertebrae and the chest region can be easily stretched by the user leaning back while the support part is in close contact with the thoracic vertebrae.

In addition, the support protrusion provided in the seat part supports the user's ischial bone when the user sits on the seat part, thereby reducing the pressure on the hamstring part behind the thigh when the user is seated, and reducing the area of the thigh touching the seat plate of the seat part to reduce sweat. This car can reduce symptoms, and due to the position of the sciatic bone supported by the support process, the center of gravity of the leg is lowered forward, so that the upper body can be comfortably erected.
