Description

Chair with standing-up aid

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an upright supporting chair, and more particularly, to an upright supporting chair for assisting standing of a person who is difficult to stand by using a simple cylinder structure.

As the society enters the aging society, the need for product development and evaluation for the elderly is becoming important, and the demand for products supporting the safe daily life of the elderly is increasing. In particular, the demand for assistive devices for daily life support, which can support the self-reliance of the elderly in daily life, has been greatly increased due to the increase of the elderly living alone.

On the other hand, the safety accidents of the elderly are more likely to occur in the home than in the outside, such as the entrance hall and the bathroom. In addition, not only is the rising motion of the elderly person sitting on the floor a great burden, The center of gravity of the center of gravity,

According to the results of analysis of the elderly person safety accident, more than half of the types of safety accidents appear to be falls. This situation is also the case for people with disabilities and difficult-to-stand patients. Accordingly, a chair capable of standing up assistance for the elderly, the disabled, or patients who are difficult to stand up has been developed.

Korean Registered Patent No. 10-1176945 (registered on Aug. 20, 2012) describes a standing-up assistant chair for assisting the elderly, the disabled, and patients to stand upright. It is fixed to the horizontal frame and the horizontal frame at an angle A main frame having a longitudinally mounted frame; A chair seating surface which is horizontally movable on the horizontal frame and can be seated by the user; An electric driver for hinging the front end of the chair seat to the front end of the chair seat to horizontally move the seating surface of the chair; A seat guide installed at a rear side of the main frame and connected to the seating surface of the chair for guiding the horizontal movement of the seating surface of the chair and the rotation about the front end when the seating surface of the chair moves forward or backward by the operation of the electric actuator; A back plate hinged to the rear end of the seating surface of the chair and supporting the back of the user; A back plate guide provided on the vertical side frame so as to extend in the vertical direction; The lower end of the seat is hinged to the rear end of the seating surface of the chair and the upper end of the seat is guided by the backrest guide to move in the up and down direction. And a back plate support for varying the angle of the back plate while receiving and moving. According to the disclosed technique, the standing support function and the reclining function of the chair help the user of the elderly person, the disabled person, or the patient to easily change their posture, and by controlling these functions with a single driver, The cost and volume of individual installations can be reduced.

Korean Patent Registration No. 10-1041621 (Registered on Jun. 8, 2011) relates to a chair device for assisting standing in an indoor entrance to prevent an accident of a senior citizen, and a chair is raised and lowered by utilizing a pulley- So as to minimize the space occupied by the standing-up auxiliary chair in a narrow indoor hall by allowing the standing-up auxiliary chair to have the simplest form. According to the disclosed technique, there are provided a base portion fixed to a wall surface; A lift portion; A guide portion for guiding the elevation portion with respect to the base portion; wire; A fixing part fixed to the base part to support one end of the wire; A winding sheave that supports the other end of the wire; A power transmission part installed in the elevating part and transmitting rotational power to the winding sheave; Wherein the rotating shaft of the winding sheave is vertically disposed on the plane of the base portion and the elevating portion also ascends and descends when the winding sheave is lifted or lowered, whereby the rotation shaft of the winding sheave is perpendicular to the plane of the base portion Since the thickness of the pulley is thickened by the thickness of the pulley, it is possible to arrange it in a narrow indoor porch as much as possible, and it is possible to easily raise the height of the chair desired by the user by controlling the height of the elevator by the limit switch. The tension of the wire can be controlled by supporting the one end of the wire by hanging the wire by the threaded portion and the nut by the supporting bracket and by folding the chair, Can contribute to slimness of thickness The foldable frame is accommodated in the receiving groove and is not exposed when viewed from the outside, so that the foldable frame is not exposed when viewed from the outside, And a magnet is mounted on the upper case portion and the chair so as to keep the chair in a folded state, thereby contributing to slimming down.

The above-mentioned conventional standing up support chair can be broadly divided into a form capable of supporting standing in a sitting position on the floor and a form supporting a standing position in a sitting position on a chair.

It is difficult to simultaneously adjust the height of the seating surface and the angle of the back plate owing to the structure of the mechanism for supporting the chair mechanism.

In the case of an upright standing chair in the form of a chair, it is possible to perform various operations such as tilting the back plate or lifting the legs. However, the number of actuators used is large, and it is difficult to assist the standing of the elderly sitting on the floor.

A new type of stand-up assistance chair structure that complements the disadvantages of such conventional stand-up assistance chairs is needed.
