Description

지면 반력 측정 장치Ground reaction force measuring device
본 발명은 지면 반력 측정 장치에 관한 것으로서, 더욱 상세하게는 발바닥 전체 면적이 아닌 다수의 특정 영역마다 한 개 이상의 소형 힘센서를 배치하고, 상기 힘센서들 사이에는 연성재질부재가 채워지고, 발바닥과 마주하는 면에는 족저압이 상기 힘센서로 전달되도록 하는 탄성부재를 선택적으로 구비함으로써 지면 반력을 측정할 수 있는 지면 반력 측정 장치에 관한 것이다.More particularly, the present invention relates to an apparatus for measuring a ground reaction force, and more particularly, to an apparatus for measuring a ground reaction force, comprising at least one small force sensor for a plurality of specific areas, And a surface reaction force measuring device capable of measuring a ground reaction force by selectively providing an elastic member that allows the foot pressure to be transmitted to the mutually facing surfaces.
사람의 보행을 분석하는 연구는 재활 치료, 보행 보조 로봇, 질병 진단 등의 목적으로 다양하게 활용되고 있다. 최근에는 신경, 근육 손상으로 인한 보행 이상을 체크하거나 뇌성마비 등의 질환에 있어서 수술 여부를 결정하는 과정에도 활용되고 있다. 이러한 보행 분석을 위해 일반적으로는 힘판(Force Plate, 포스 플레이트) 또는 족저압 분석장치 등을 이용한 지면반력 측정방법이 많이 사용되고 있다.Research on human walking is widely used for rehabilitation, walking robot, and diagnosis of diseases. In recent years, it has also been used in the process of determining whether or not to undergo surgery for diseases such as cerebral palsy or checking gait abnormalities caused by nerve and muscle damage. Generally, a floor reaction force measurement method using a force plate (force plate) or a pedestal low pressure analyzing device is widely used for the gait analysis.
보통의 족부압력 측정은 잉크를 이용하여 발바닥 접촉면을 종이에 찍어보거나, 복수 개의 압력센서가 배치된 힘판(Force Plate)를 이용한 측정장비로 단위면적의 압력을 순차적으로 측정하는 방법이 쓰이는데, 측정 결과물은 단위면적 압력의 색상을 변화시킨 모자이크 그래프로 표시된다.Regular foot pressure measurement is a method of measuring the pressure of a unit area sequentially by measuring the contact surface of the sole with ink using ink or by using a force plate equipped with a plurality of pressure sensors, Is represented by a mosaic graph in which the hue of the unit area pressure is changed.
그러나 이러한 측정결과는 신발을 신지 않은 상태로 평판 또는 힘판 위에서 보행하면서 얻어진 것으로서, 보행거리의 제한성 때문에 한정된 동작에 한하여 측정이 가능하다는 문제점이 있다.However, these measurement results are obtained by walking on a flat plate or a plate without wearing shoes, and there is a problem in that measurement can be performed only for a limited operation due to limitation of the walking distance.
그리고, 힘판 또는 족저압 분석장치는 실내에 고정되어 설치되기 때문에, 계단이나 실외 환경에서는 사용이 불가능하여 지면 반력을 측정할 수 있는 공간이 제한된다. 또한, 한정된 힘판 및 분석장치의 개수와 한정된 측정 영역으로 인해 힘판 및 분석장치 위의 한정된 걸음에 대해서만 지면반력을 측정할 수 있으므로 연속적인 걸음을 측정하기 위해서는 다수 개의 힘판을 보폭에 맞게 설치해야 하는 단점이 있다. 또한, 힘판은 고가의 장비이므로 다수 개의 힘판을 사용하는 것은 비용적인 부담이 크고 이러한 이유로 일부 연구기관에서만 적용이 가능한 실정이다.Since the force plate or foot pressure analyzer is fixedly installed in a room, it can not be used in a staircase or an outdoor environment, and thus a space for measuring the reaction force of the floor is limited. In addition, since the number of limited force plates and the number of analytical devices and the limited measuring range can measure the ground reaction force only for a limited step on the force plate and the analyzing device, it is necessary to install a plurality of force plates in accordance with the stride . In addition, since the force plate is expensive, it is costly to use a plurality of force plates, and therefore, it is applicable only to some research institutes.
도 1은 종래기술에 따라 지면 반력을 측정하기 위한 센서가 부착된 신발의 정면 사진이다.1 is a front view of a shoe with a sensor for measuring ground reaction force according to the prior art.
도 1에 도시된 바와 같이, 종래의 지면반력 측정 장치는 신발에 부착하는 형태이며, 발의 앞과 뒤에 센서를 1개씩 배치하고 센서의 아랫면에 판재를 덧대서 발바닥 면적을 커버했다.As shown in FIG. 1, a conventional floor reaction force measuring device is attached to a shoe, and one sensor is disposed in front of and behind the foot, and a plate is placed on the bottom of the sensor to cover the foot area.
그러나, 종래의 지면반력 측정 장치가 부착된 신발은 높이가 높고 앞쪽 센서가 중족관절 굽힘을 막기 때문에 자연스러운 보행을 저해하게 된다. 또한, 돌을 밟거나 계단을 내려올 때와 같이, 앞쪽 센서와 뒤쪽 센서 사이의 공간에 힘이 가해지게 될 때는 이를 감지할 수 없는 단점이 있다. 신발의 높이를 낮추기 위해서는 센서가 신발에 삽입이 되어야 하는데, 삽입된다 하더라도 후자의 문제는 해결할 수 없다.However, the shoes having the conventional floor reaction force measuring device are high in height and the front sensor obstructs the bending of the middle joint, which hinders natural walking. It also has the disadvantage of not being able to detect when a force is applied to the space between the front sensor and the rear sensor, such as when a person steps on a stair or steps down. In order to lower the height of the shoe, the sensor must be inserted into the shoe. Even if the shoe is inserted, the latter problem can not be solved.
즉, 발바닥 전체에 가해지는 정확한 힘을 측정하기 위해서는 센서 어레이 형태 또는 다수의 소형 힘센서가 필요하다. 하지만 필름형 압력센서가 아닌 정밀 힘센서 또는 로드셀은 매우 고가의 센서이며 크기도 필름형 압력센서에 비해서 크기 때문에 발바닥 전체에 배치할 수 없다. 따라서 제한된 센서의 숫자로 발에 가해진 반력을 측정하는 방법이 필요하다.That is, in order to measure the exact force exerted on the sole, a sensor array type or a plurality of small force sensors are required. However, a precision force sensor or a load cell other than a film type pressure sensor is a very expensive sensor, and its size is larger than that of a film type pressure sensor. Therefore, a method of measuring the reaction force applied to the foot by a limited number of sensors is needed.

제1 탄성부재(400) 및 제2 탄성부재(500)는 접착제 또는 볼트 체결 등으로 연성재질부재(210)와 체결되는데, 탄성부재가 모두 금속재질일 경우, 굴곡이 잘 되지 않을 수 있다. 따라서, 제1 탄성부재(400) 및 제2 탄성부재(500) 중 어느 하나는 비금속재질이 되는 것이 바람직하다.The first elastic member 400 and the second elastic member 500 are fastened to the flexible material member 210 by an adhesive or a bolt fastening or the like.

탄성부재가 발바닥 영역 전체 면에 형성된 경우, 강성이 커서 보행 및 지면 반력 측정이 잘 되지 않을 수 있다. 이에, 탄성부재의 강성을 줄이기 위해 두께를 얇게 할 수 있다.When the elastic member is formed on the entire surface of the plantar area, the stiffness is large and the walking and ground reaction force measurement may not be performed well. Therefore, the thickness can be reduced to reduce the rigidity of the elastic member.
또한, 상기 탄성부재(600)를 상부에서 아래를 볼 때 힘센서가 모두 덮이도록 면으로 형성되고, 힘센서를 덮은 영역 간 또는 힘센서를 덮은 영역과 외부 테두리 사이에는 선형으로 연결되는 골격 형태를 가지도록 형성할 수 있다.The elastic member 600 is formed so as to cover all the force sensors when viewed from the top to the bottom, and has a skeletal shape that is linearly connected between the areas covered with the force sensor or between the areas covered with the force sensor and the outer edges. As shown in FIG.

In order to reduce the rigidity of the elastic member, the elastic member may be formed to have a plurality of perforations.
보행시 발은 보행 방향과 수직인 방향으로 굴곡이 생긴다. 따라서, 타공의 모양은 원형도 가능하지만, 보행 방향에 직교하는 방향으로 긴 타원형의 타공(710)을 형성하는 것이 더 효율적이다. 이때, 다수의 힘센서(201 내지 204)는 노출되지 않도록, 상기 다수의 힘센서가 위치한 영역에는 타공을 형성하지 않는다.When walking, the foot is bent in a direction perpendicular to the walking direction. Therefore, although the shape of the piercing hole can be circular, it is more effective to form the long piercing hole 710 in the direction orthogonal to the walking direction. At this time, no holes are formed in the area where the plurality of force sensors are located so that the plurality of force sensors 201 to 204 are not exposed.

Accordingly, the elastic member can be divided into a plurality of specific regions.
한편, 보행시 발은 보행 방향과 수직인 방향으로 굴곡이 생긴다. 이에, 도 8에서는 일실시예로 탄성부재를 3개의 부분으로 나누는 경우를 설명하기로 한다.On the other hand, when walking, the foot is bent in a direction perpendicular to the walking direction. 8, a case where the elastic member is divided into three parts will be described as an embodiment.
