Description

방석의 구조{A SEAT}Cushion Structure {A SEAT}

본 고안은 방석의 구조에 관한 것으로, 좀 더 엄밀하게는 방석 또는 방석용 내피로 사용할 수 있도록한 방석의 구조에 관한 것이다.The present invention relates to the structure of the cushion, and more particularly to the structure of the cushion to be used as a cushion or cushion inner shell.

일반적으로 방석은 사용자의 편의를 위하여 흔히 사용되는 것인데, 다양한 구조로 구성하여 사용되어 오고 있다.In general, cushions are commonly used for the convenience of users, and have been used in various structures.

그런데 이러한 종래의 방석을 살피면, 상단이 주로 편평한 상태를 유지하는 것이 대부분이여서 엉덩이와 방석사이가 밀착되지 않아 착석이 불안정하여 불편함이 따르고, 특히 운전자 또는 학생들과 같이 장 시간 착석하는 경우에는 어느 한쪽으로 쏠리는 문제점이 있어서 앉는 자세를 흐트리는 문제점이 필수적으로 수반되게 된다.By the way, if you look at such a conventional cushion, the upper part is mainly to maintain a flat state is not close contact between the buttocks and cushions, unstable seating is uncomfortable, especially when sitting for a long time, such as drivers or students There is a problem to be drawn to the problem of obscuring sitting posture is necessarily accompanied.

본 고안은 상기한 종래의 방석이 가지는 문제점을 해결하고자 하여 착석자의 안정감과 바른 자세로 착석케 하는데 있다.The present invention is intended to solve the problem of the conventional cushion described above to be seated in a seated person with a sense of stability and correct posture.

이러한 종래의 방석이 가지는 문제점의 해결과 본 고안의 목적을 달성하기 해 본 고안에서는 방석의 형태를 구성하는 몸체의 내부에 내측면을 따라 턱을 형성한 요홈부를 구성하고, 상기 요홈부의 중앙에 일정한 길이를 가진 돌기부를 구성한 방석을 제공함으로서 가능하였다.To solve the problems of the conventional cushion and the object of the present invention to achieve the object of the present invention comprises a concave groove formed in the jaw along the inner surface of the body constituting the shape of the cushion, constant in the center of the groove It was possible by providing a cushion comprising a protrusion having a length.

이하 본 고안의 바람직한 실시형태에 대하여 첨부한 도면 도 1 및 도 2에 의거하여 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, FIGS. 1 and 2.

방석의 형태를 구성하는 몸체(1)의 내부에 내측면을 따라 턱(5)을 형성한 요홈부(2)를 구성하고, 상기 요홈부(2)의 중앙에 일정한 길이를 가진 돌기부(3)를 구성한 방석(4)의 구조를 제공한다.Concave portion (2) forming a jaw (5) formed along the inner surface of the body (1) constituting the shape of the cushion, the projection (3) having a constant length in the center of the groove portion (2) It provides a structure of the cushion (4) consisting of.

이때 상기한 돌기부(3)는 앞쪽을 향하면서 높게 구성한다.At this time, the protrusion 3 is configured high while facing forward.

이러한 본 고안의 방석은 금형으로 제작하는 가능한 재질인 폴리 우레탄 폼 또는 조각을 통한 나무로도 제작이 가능하다.The cushion of the present invention can also be made of wood through a polyurethane foam or a piece of material that can be produced in a mold.

특히 착석시의 안정감 또는 안락성을 위하여 적당한 쿠숀을 유지하는 재질이 바람직하다.In particular, a material that maintains a proper cushion for seating stability or comfort is preferable.

이러한 재질은 상기한 바와 같은, 폴리 우레탄 폼 또는 이와 유사성이 있는 폴리 프로필렌 폼으로의 제조가 가능할 것이며, 고무재로의 제조도 가능하다.Such a material may be made of a polyurethane foam or a polypropylene foam having similarity as described above, and may also be made of a rubber material.

이러한 구조으 본 고안은 상기한 바와 같은 형태로 제작한 그대로의 것으로도 사용이 가능할 것이며, 이를 섬유재질 또는 이와 유사한 재질을 가진 외피에 삽입하여 사용할 수 있다.With this structure, the present invention may be used as it is produced in the form as described above, it can be used by inserting it into the outer sheath having a fiber or similar material.

물론 상기한 방석을 구조를 가지는 몸체(1)는 도면상에서는 사각형의 형태로 도시하고 있으나 이는 원형 또는 타원형 등 외형은 얼마든지 변경하여 실시할 수 있는 것임은 물론이다.Of course, the body 1 having the structure of the cushion is shown in the form of a square in the drawing, but this is a matter of course that can be carried out by changing the appearance, such as round or oval.

이러한 본 고안의 구조를 가진 방석(4)은 착석시에 엉덩이가 길이가 긴 형상의 돌기부(3)를 중심으로 양쪽의 요홈부(2)에 안정적으로 밀착되면서 착석이 가능학, 또한 요홈부(3)를 구성하는 몸체(1)의 턱(5)이 엉덩이의 바깥쪽을 지지하여 주기 때문에 안정정인 착석 및 바른 자세로 착석할 수 있게 있다.Cushion (4) having a structure of the present invention can be seated while being stably in close contact with the grooves (2) on both sides of the protruding portion (3) having a long shape when seated, and also grooves ( 3) Since the jaw 5 of the body 1 constituting the support of the outside of the hip can be seated in a stable sitting and a correct posture.

그리고 상기한 돌기부(3)은 엉덩이의 앞쪽 사이와 그 사이를 통하는 허벅지및 생식기가 위치하는 쪽의 공간에 위치하게 하여 착석시 자세가 어느 방향으로 쏠리지 않으면서 착석되도록 유도하여 바른 자세로 착석이 가능하게 할 수 있다.And the protrusion (3) is located in the space between the front of the hips and the thighs and genitals through the space between the induction to be seated without sitting in any direction when sitting can be seated in the correct posture It can be done.

특히, 상기한 돌기부(3)는 앞쪽을 향하면서 높게 구성하여 착석시 엉덩이 앞쪽 사이에서 허벅지 사이 및 생식기 사이에서 발생하는 인체의 공간부에 위치할 수 있게 하여 착석시의 안정감 및 바른 자세의 착석을 유도하게 된다.In particular, the protrusion part 3 is configured high toward the front to be located in the space of the human body generated between the front of the hips between the thighs and the genitals during sitting so that the seating of the sense of stability and correct posture during sitting To induce.

이러한 본 고안은 필요에 따라 그 기능을 추가할 수 있는데 이를 첨부한 도면 도 3 및 도 4에 도시하고 있는 바와 같이, 엉덩이가 착석되는 요홈부(2)에 옥돌, 맥반석, 자석등과 같이 인체에 유익한 것으로 알려진 자력방사나 원적외선 방사재(6)를 삽입하여 고정할 수 있으며, 이러한 설치는 상기한 요홈부(2)에 구멍(7)을 형성하여 접착재등을 이용하여 삽입 고정하는 방법을 사용한다.The present invention can be added to the function as needed, as shown in Figures 3 and 4 attached to this, buttocks (2) in which the butt is seated in the human body, such as jade, elvan, magnet, etc. Magnetic radiation or far-infrared radiating material 6 known to be beneficial can be inserted and fixed, and such installation uses a method of inserting and fixing using an adhesive or the like by forming a hole 7 in the recess 2. .

이때에도 상기한 보조재료(6)는 지압의 효과를 위하여 약간 상부로 돌출시킬 수도 있으며, 자압에 따른 착석시의 이질감을 방지하기 의해서는 완전히 매몰시키는 방법에 의거하여 삽입고정하는 방법도 가능할것이다.In this case, the auxiliary material 6 may protrude slightly upward for the effect of acupressure, and it may be possible to insert and fix it based on a method of completely burying, in order to prevent heterogeneity during sitting due to magnetic pressure.

또한 본 고안의 방석에는 첨부한 도면 도 5에서 도 8에서 도시하고 있는 바와 같이 본체(1)의 저면에 삽입구멍(8)을 형성하고, 그 내부에 통상적으로 사용되고 있는 진동모터와 같은 바이브레이타(9)를 설치하여 이 바이브레이타(9)의 작동에 의하여 발생하는 진동이 본체(1)에 전달되도록 하여 착석시 발생하는 엉덩이 근육은 물론이고 이에 맞닿아 있는 허벅지등을 포함하여 그 진동력을 통해 인체의 전체를 통하여 전달되게하여 인체의 피로를 해소시키는 방법으로 이용될 수 있다.In addition, the cushion of the present invention forms an insertion hole 8 in the bottom surface of the main body 1 as shown in Figs. 5 to 8 of the accompanying drawings, and a vibrator such as a vibration motor which is commonly used therein. Vibration force generated by the operation of the vibrator (9) to be transmitted to the main body (1), including the hip muscles generated when sitting, as well as the thighs that are in contact with the vibration force Through the entire body through the body can be used as a way to relieve fatigue.

이러한 바이브레이타(9)의 작동을 위해서는 통상적으로 상용하는 전원장치를 이용하여 자동차용 보조 방석으로 사용할 시에는 자동차의 시거잭을 통한 전원을 이용하여 사용이 가능하다.For the operation of the vibrator (9) when using a car auxiliary cushion using a commercially available power supply can be used using the power through the cigar jack of the car.

이러한 본 고안에 의하면, 방석의 형태를 구성하는 몸체(1)의 내부에 엉덩이를 받칠수 있는 요홈부(2)와, 상기 요홈부(2)의 중앙에 엉덩이의 전방을 따라 받칠수 있는 적당한 길이를 가진 돌기부(3)를 구성한 방석(4)을 제공함으로서, 착석시의 안정감 및 바른 자세와 함께 피로감을 해소시킬 수 있는 구성의 방석을 제공하는 것임을 알 수 있다.According to the present invention, the groove portion 2 that can support the hip in the interior of the body (1) constituting the shape of the cushion, and the appropriate length that can be supported along the front of the hip in the center of the groove portion (2) It can be seen that by providing a cushion (4) consisting of a projection (3) having a, it is to provide a cushion having a configuration that can relieve fatigue with a sense of stability and correct posture when sitting.

따라서 본 고안은 방석의 형상과 함께 그 구성 요소의 모양이나 형상 및 기능의 추가, 구성요소가 가지는 갯수의 차이 및 돌기부의 형상은 얼마든지 설계 변형이 가능하므로 결국 상기한 바와 같이 본 고안이 가지는 방석의 고유 기능을 행할 수 있도록 하는 내용의 기술은 결국 균등론에 입각하여 본 고안의 권리범위에 속하는 것임을 부언한다.Therefore, the present invention, as well as the shape of the cushion, the addition of the shape and shape and function of the components, the number of components and the shape of the projections can be any number of design modifications, so the cushion of the present invention as described above It is added that the description of the contents that enable the inherent function of is within the scope of the present invention based on the theory of equality.

이상 상기에서 살핀 바와 같이, 본 고안의 방석은 착석자의 안정감 및 바른 자세의 유도를 통하여 방석이 가지는 그 고유 기능을 최대화할 수 있는 매우 유용한 고안이다.As described above, the cushion of the present invention is a very useful design that can maximize the unique function of the cushion through the induction of the seater's sense of stability and correct posture.
