Description

전동목발{CRUTCH MOVED BY AN ELECTRIC MOTOR}{CRUTCH MOVED BY AN ELECTRIC MOTOR}

본 고안은 모터부와 구동바퀴부를 구비한 전동목발에 관한 것이다.The present invention relates to an electric crutches having a motor unit and a drive wheel unit.

목발은 보행에 불편함이 있는 사람들을 보조하는 도구. 하지에 직접 체중이 실리지 않도록 하여 걸을 때 몸의 균형을 최소한 유지하거나 상한 다리를 대신할 수 있다.Crutches are tools to assist people with discomfort in walking. When you walk, you can keep your balance at a minimum or replace your upper legs by avoiding weight directly on your lower legs.

이른바 걷는데 불편함이 있는 노인분들이나 선천/후천적으로 인한 사고인해 걷는 능력을 손실한 대상, 혹은 그 외적인 요인(질병, 사고, 소음..등)으로 인해 보행에 어려움을 겪는 대상이 걷는 것을 도와주는 도구이다.The elderly people with so-called uncomfortable walking, those who have lost their ability to walk due to inherited / acquired accidents, or those who are struggling to walk due to external factors (diseases, accidents, noise, etc.) Tool.

표준형 목발은 이동시 겨드랑이에 상당한 충격 및 하중이 가해져 통증을 유발하며, 또한, 구조적으로 환자 스스로 다리를 지면으로부터 띄워야 하므로, 다친 다리에 피로감을 주게 되고, 그로 인하여 중장거리 보행에 무리가 있다.The standard crutches cause significant pain and impact on the armpits when they are moved. In addition, since the legs must be lifted from the ground by the patients themselves, fatigue is caused on the injured legs, which makes it difficult to walk the middle and long streets.

본 발명은 상기와 같은 문제를 해결하기 위해 목발에 모터부와 구동바퀴부를 구비하여 평지, 또는 계단에 사용할 시에도 피로감을 줄이는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a motorcycle and a driving wheel portion in a crutch for reducing tiredness even when used on a flat or stair.

본 발명의 실시예에 따른 전동목발은 전동구동의 편리함을 목발에 접목하여 평지 및 계단을 이용함에 있어 좀더 자유로운 보행을 돕게 된다.An electric crutch according to an embodiment of the present invention combines the convenience of electric driving with crutches to help a person walk more freely in using a flat ground and a stair.

이상에서 살펴본 바와 같이 본 발명은 평지에도, 계단에서도 사용자가 힘을 많이 들이지 않아도,자동, 혹은 수동으로 구동이 가능한 구동바퀴부를 장착하였다. 계단을 이용할시에는 보다 세심한 주의와 조작이 따라야 함은 물론이며, 이를 뒷받침하는 구조와 성능을 갖추었을 때 본 발명에 따른 용도에 따른 근접한 효과를 낼 수 있다.As described above, the present invention is equipped with a drive wheel unit that can be driven automatically or manually even if the user does not need much power on the ground or the stairs. When the stairs are used, careful attention and manipulation must be followed, and when the structure and performance supporting the stairs are provided, it is possible to obtain a close effect according to the use according to the present invention.

전동목발은 견착대(11)와 로드(12)와 손잡이(13)와 제어스위치(14)를 연결하며, 모터부(21)와 길이조절부(22)와 구동스위치(23)를 포함하며 구동바퀴부(30)에 타이밍벨트(31)와 주행휠(32)과 포크휠(33)과 원웨이 체인(34)과 휠 스프포킷(35)과 회전축(36)을 포함하는 것을 특징으로 한다The electric crutch is connected with the cradle 11, the rod 12, the handle 13 and the control switch 14, and includes a motor portion 21, a length adjusting portion 22 and a drive switch 23, A wheel 30 is provided with a timing belt 31, a traveling wheel 32, a fork wheel 33, a one-way chain 34, a wheel spoke kit 35 and a rotary shaft 36

견착대(11)와 손잡이(12)는 수평을 이루는 것을 특징으로 하며 상부 로드(12-1)와 하부 로드(12-2)는 30~45도 정도 꺾이는 것을 특징으로 하며 이는 계단의 오르내릴 때, 뒤로 넘어가는 것을 방지한다.The upper end of the upper rod 12-1 and the lower end of the lower end of the lower rod 12-2 are bent by about 30 to 45 degrees, , Preventing it from falling back.

타이밍벨트(32)는 3개의 주행휠(32)을 연결하며 이 주행휠(32)은 회전축(36)과 포크휠(33)과 원웨이 체인(34)과 휠 스프로킷(35)가 맞물려 구동된다.The timing belt 32 connects the three traveling wheels 32. The traveling wheel 32 is driven by engaging the rotating shaft 36 and the fork wheel 33 with the one way chain 34 and the wheel sprocket 35 .

상기 포크 휠(33)은 회전축(36)에 중심부을 3분 균등하여 연장 형성한 지지편으로 내부에 공간이 있게 하며 그 세 방향의 선단 일측에 상기 주행 휠(32) 을 고정하여 설치한다.The fork wheel 33 is a supporting piece formed by extending the central portion of the rotating shaft 36 evenly for three minutes, and has a space therein. The fork wheel 33 is fixed to one side of the leading end of the fork wheel 33 in three directions.

본 발명에 따른 전동목발의 구동장치는 구동스위치(23)과 제어스위치(14)로 그 구동과 제어가 결정되는 것을 특징으로 한다. 구동스위치(23)를 누르면 모터부(21)에 연결된 구동바퀴부(30)가 작동되어 구동되며 구동된 목발의 제어는 제어스위치(14)로 브레이크의 역할을 한다.The driving device for an electric powered carcass according to the present invention is characterized in that driving and control thereof are determined by a driving switch (23) and a control switch (14). When the driving switch 23 is pressed, the driving wheel portion 30 connected to the motor portion 21 is actuated and driven, and the control of the driven crutch is controlled by the control switch 14 as a brake.

이하, 본 발명에 따른 휠체어의 세부 사항과 일 실시예의 작용을 자세히 기술한다. 계단은 보통 높이 15 ~ 17㎝정도 에, 30 ~ 34㎝정도의 폭을 가진다. Hereinafter, the details of the wheelchair according to the present invention and the operation of one embodiment will be described in detail. The stairs are usually 15 to 17 cm high and 30 to 34 cm wide.

바퀴가 계단에 안정되게 하면 이상적이라 할 것이나 실제에 있어서 계단의 폭은 많이 좁은 편이므로 여기서는 계단의 높이를 16~17㎝정도에 폭을 30~32㎝정 도로 등판각을 30°이내로 하며 상기 주행휠(32)의 지름을 16㎝정도에 각 휠 간의 사이를 4~5㎝정도로 한다. It is ideal if the wheel is stabilized on the stairs, but since the width of the stairs is actually narrow, the height of the stairs should be 16 ~ 17 cm, the width should be 30 ~ 32 cm, The diameter of the wheel 32 is about 16 cm and the distance between the wheels is about 4 to 5 cm.

상기 포크휠(33)을 1회전하면 상기 포크 및 주행휠(32)의 둘레보다 주행휠(32)의 진행한 거리가 수㎝정도 길어지는데 이는 실제로 계단에서 오르내릴 때 바퀴의 위치를 적절하게 하는 역할을 한다. When the fork wheel 33 is rotated one time, the traveling distance of the traveling wheel 32 is longer than the circumference of the fork and the traveling wheel 32 by about several centimeters. This is because the position of the wheel is appropriately adjusted It plays a role.

구동바퀴부(30)의 구동력은 모터부(21)에서 타이밀 벨트(31)를 통해서 구동바퀴부(30)을 회전시킬 수 있다.The driving force of the driving wheel 30 can rotate the driving wheel 30 through the tie-wheel belt 31 at the motor 21.

모터부(21)는 별도로 구비된 배터리 등의 저장수단으로 전기에너지를 전달받아 구동될 수 있다.The motor unit 21 may be driven by receiving electrical energy from a separate storage unit such as a battery.

상기한 모터부(21)의 전동장치는 12V출력의 배터리와 표준 DC모터를 사용하여 회전을 하도록 한다.The power unit of the motor unit 21 rotates using a 12V output battery and a standard DC motor.

이는 분당 50~60rpm까지 회전이 가능하나 실제로 보행시에는 이의 4분의 1에서 5분의 1의 회전력만으로도 보행이 가능하다.It can be rotated to 50 ~ 60 rpm per minute, but when walking, it is possible to walk with only 1/4 to 1/5 torque.

따라서 계단이용시 상기한 포크휠(33)이 1회전 할 때 3계단 상승시 부하를 감안하여 5~6초 정도의 안정적인 속도를 내도록 한다. Accordingly, when the fork wheel 33 is rotated one step, when the stairs are used, a stable speed of about 5 to 6 seconds is provided in consideration of the load at the time of three steps rising.

본 발명의 기술 사상은 상기 바람직한 실시 예에 따라 구체적으로 기술되었으나, 상기한 실시 예는 그 설명을 위한 것으로 상기 설명된 실시 예에 제한하는 것은 아님을 명시한다. 본 발명의 기술분야의 통상의 전문가라면 본 발명의 기술 사상의 범위 내에서 다양한 실시 예가 가능함을 이해할 수 있을 것이다.Although the technical spirit of the present invention has been specifically described according to the above preferred embodiments, it is to be understood that the above-described embodiments are intended to be illustrative and not restrictive. It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
