Abstract

PURPOSE: A seat for installing a chair is provided to disperse the pressure of the human body and to fix the hip by supporting the lower end of the hip. CONSTITUTION: A round recess(30) is formed in the center of a high density, high elasticity sponge cushion member. Around the round recess, long recesses(31) are formed. The cushion member is combined to a seat plate(40) by an outer cover(11). The outer cover is curved inward or formed integrally to surround the lower end of the seat plate. The hip of a user is lightly supported on the cushion member. A pad(50) formed in the shape the same as the round groove and the slit is included.

Description

Chair-mounted seat base {Chair-seat with a hole}

The present invention relates to a seat for providing a cushion by facing a relatively hard seat of the chair, and more specifically, a seat of a chair made of wood, plastic, steel, etc. It will be directed to a chair-mounted seat where the sciatic nodules of the buttocks are located in the grooves of the cushioning member and face the hard shell so that only a small portion of the lower end of the sciatic nodules reaches the hard seat to disperse the pressure acting on the buttocks. .

In general, a chair combined with a sponge cushion body or a chair made of wood or plastic material has a wide range of contact with the buttocks at the time of sitting, so all the pressures of the human body are concentrated on the buttocks, which results in sciatic nodules. If you are sitting for a long time, you will not be able to withstand the pressure on the sciatic nodules and lumbar vertebrae and the vertebrae connected to the hips, and the sitting posture will be disturbed or skewed. In addition, blood circulation is not smooth, causing anal diseases and muscle diseases urinary diseases.

In addition, since the surface of the seat is made of a smooth surface, it is difficult to maintain the correct posture for a long time when sitting due to the pressure of the upper body applied to the obtuse, and there is a problem of distraction such as changing the sitting posture from time to time.

The present invention forms the seat of the chair by combining the cushion member formed with a through groove in the portion where the buttocks are located, and forms the seat of the chair, and the seat plate supports the lower part of the buttocks inserted into the through groove, thereby dispersing the pressure of the human body. In addition, the purpose is to provide a base that can serve to fix the movement of the buttocks.

The present invention for achieving the above object has an area corresponding to the seat plate of the chair and a circular groove of a predetermined size penetrates in the thickness direction at the portion where the buttocks are located, and the long groove is formed in the rear and side directions of the circular groove, respectively. And a cushion member, wherein the cushion member faces the seat plate of the chair, and the edge of the cushion member is wrapped with an outer surface bent inwardly to the bottom of the chair to surround the entire upper surface of the cushion member and the bottom edge of the seat plate bottom surface of the chair. To the seat of the chair.

Furthermore, the present invention further includes a pad having the same shape so as to be detachably inserted into the through groove, but the pressure of the upper body applied to the buttocks can be dispersed by differently forming the compressive strength of the cushion member and the pad. In addition, pads can be manufactured by foaming together with polyester polyester powders of bio-infrared, charcoal, loess, etc., or for the purpose of special treatment.

In addition to this shape, springs can be mounted to reduce the impact a user receives when seated.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

Figure 1 shows a first embodiment of the present invention, Figure 1a is a perspective view of a seat coupled to the chair according to the present invention, Figure 1b is an exploded perspective view of Figure 1a, Figure 1c is a cross-sectional view of the combined state of Figure 1b to be.

Referring to the drawings, the present invention forms a circular groove 30 of the size that the buttocks can be spread in the center of the high-density, high-elastic sponge cushion member 20 and the rear and lateral direction around the circular groove 30 Long grooves 31 are formed in three directions. In the embodiment, the groove formed in the cushion member 20 is formed in a circular shape, but the present invention is not limited thereto, and may be an elliptical shape having a long axis in the width direction.

In the embodiment, the cushion member 20 is coupled to the seat plate 40 by an outer shell indicated by reference numeral 10. The outer shell 10 has a height in consideration of the height of the cushion member 20 and the seat plate 40, the upper portion has an area substantially the same as the area of the cushion member 20, the lower portion of the bottom surface of the seat plate 40 The shape is maintained by integrally molding or stitching to be bent inwardly so as to wrap the edge.

As described above, when seated in a state in which the cushion member 20 is coupled to the seat plate 40 by the shell 10, the seating position may be stabilized by gently supporting the bottom of the buttocks of the seated person.

Figure 2 shows another embodiment of the present invention, referring to the drawing further includes a pad 50 of the same shape as the shape of the circular groove 30 and the long groove 31 formed in the cushion member 21 and the pad (50) is fitted to fit.

Here, the cushion member 21 and the pad 50 need to have different compressive strengths, and therefore, the compressive strength of the pad 50 preferably has a compressive strength smaller than the compressive strength of the cushion member 21.

In addition, the present invention can obtain a therapeutic effect associated with anal diseases by foam molding the fine powder or medicine that emits far-infrared rays when foaming the pad 50, together with the foam material.

Examples of the additive added to the pad 50 may include mineral additives such as bioceramic, ocher, jade, or the like, or vegetable additives such as charcoal or wormwood, and various materials not illustrated may be added. One or more may be mixed and added from an initiator.

Charcoal has excellent antibacterial and deodorizing moisturizing effect, and it can be expected to produce heat effect because it emits far infrared rays. Especially, it is effective for the treatment and prevention of anal diseases and urinary diseases such as lower abdominal diseases (cold and cold) and constipation and hemorrhoids in women. .

In addition, it can be expected to be effective for long-time office workers and examinees, sales drivers, and users who are tired from stress and heavy work.

Figure 3 shows another embodiment of the present invention. As shown, the present invention is an enlarged cross-sectional view of a chair on which the spring 60 is mounted on the pedestal 2, viewed from the side, with the plate member 42 interposed between the cushion member 22 and the seat plate 40. The spring 60 can be attached between the 42 and the seat plate 40. In this case, when the user is seated on the chair, the spring 60 absorbs the shock to alleviate the shock and prevents the spine from going to the spine when seated.

The present invention made as described above, by forming a circular groove in the cushion member to distribute the anti-pressure received by the buttocks at the time of seating to facilitate blood circulation, to prevent anal diseases or urinary diseases, always sitting posture In addition to preventing spinal diseases and reducing fatigue, students can improve their concentration.

In addition, the present invention can be expected to moisturize, moisture-proof, deodorant and warming effect by adding an additive that can obtain far infrared rays or therapeutic effect on the pad, especially in women's lower abdominal diseases (cold, crayfish), constipation, hemorrhoids, anal or urinary It is effective for the disease.
