Description

[Detailed Description of the Invention] Purpose An ordinary chair has a fixed backboard angle and a fixed seat height, and cannot be freely transformed according to the user's physique or purpose of use. There are other chairs with backboards that can be raised and lowered, but they use metal fittings or springs as the raising and lowering device, making them time-consuming to manufacture, prone to breakdowns, and cumbersome to operate. As an alternative to these, chairs are also used in which a large number of small foamed resin balls are housed in a bag-like covering cloth, which is integrated through the back and seat, but the shape is different for use as a sitting chair or reclining chair. When changing the seat, it is difficult for the user to smoothly move the small balls on the seat to the back and the small balls on the back to the seat if the user presses his or her waist or back while sitting. The object of the present invention is to eliminate such inconveniences, to facilitate the conversion between sitting and lying positions, and to improve physical health by providing a magnet in the backrest.

Structure The present invention connects the back and the seat, and a large number of lightweight small balls 2 made of synthetic resin foam are placed in a covering cloth 1 that corresponds to the back, the total volume of which is slightly smaller than the volume of the covering cloth. In this chair, a synthetic resin sponge foam 4 is housed in a covering fabric 3 of the seat part, and in this structure, a number This chair is made of two small magnets attached with support cloth 6 with their spherical surfaces facing outward.

Functions and Effects In the present application, the sponge foam 4 is housed in the seat, so it is easy to sit and the sitting position is stable.

Inside the back, a light foam ball is placed in an amount slightly smaller than its volume, so when you press it with your weight, the ball moves freely, but the ball is only placed in the back, unlike conventional products. Since you can't pass it all the way to the seat, you can move it smoothly while sitting. In other words, when the user presses his or her lower back strongly against the lower back of the chair while sitting, the small balls will naturally move toward the upper back of the chair, and the back will be in a standing position, allowing the user to use the chair while sitting on the seat ( Figure 8). Next, when the user presses the upper part of the back with his/her back, the small ball moves to the lower part and the back falls backward, allowing the user to lie down on it (Figure 9).

As described above, it is very convenient to be able to freely convert from a sitting position to a sitting position or a lying position, and since no wire or spring is used in the conversion mechanism, it is easy to manufacture and there are fewer occurrences of malfunctions.

A magnet 5 is provided on the inner surface of the covering cloth 1, which corresponds to the front of the back.When the user presses his/her back against this magnet, the magnetic effect and acupressure effect improve blood circulation, which relieves stiffness and pain in the shoulders and lower back. Physical disabilities are removed. Therefore, if magnets are placed at acupuncture points on both sides of the user's spine, the therapeutic effect will be even more effective.
