Description

전동 기립형 휠체어{A wheelchair which can stand up by electric power}Electric standing up wheelchair {A wheelchair which can stand up by electric power}

본 발명은 전동 기립형 휠체어에 관한 것으로, 더욱 상세하게는 한국인의 체형 조건에 맞추어 구성되어 있으며, 휠체어 사용중 사용자가 작업을 위해 직립 가능하고, 또한 직립된 상태에서 사용자의 안정성을 고려하여 기립후 지면과의 고정방식과 신체를 지지하는 이중 안전 장치로 된 것이다.The present invention relates to an electric standing wheelchair, and more particularly, is configured in accordance with the body conditions of the Korean, the user can stand up for work during the use of the wheelchair, and also after standing the ground in consideration of the stability of the user in the standing state It is a double safety device that supports the body and the body.

질병이나 사고에 의한 장애인과 더불어 노령화에 따른 근 골격계 퇴화로 노령 장애인이 증가하고 있다. 이러한 장애인의 대표적인 이동수단으로 휠체어가 사용되고 있으나 이에 반하여 국내 휠체어 개발기술은 낙후되어 있는 상태다.Older people with disabilities are increasing due to deterioration of musculoskeletal system due to aging as well as disabled people due to diseases and accidents. Wheelchairs are used as a representative means of transportation for the disabled, but domestic wheelchair development technology is underdeveloped.

현재 사용되고 있는 전동 휠체어는 실내 및 실외에서 모터 구동력에 의해 원하는 위치로의 이동이 쉽다.Currently used electric wheelchairs are easy to move to a desired position by motor driving force indoors and outdoors.

하지만 사용자가 작업을 위해 일정 높이를 필요로 할 때 상체를 일으키거나 다른 기구를 사용해야한다. 이러한 동작은 신체의 움직임이 불편한 사용자에게 위험을 초래할 수 있다.However, when the user needs a certain height for work, he must raise his upper body or use other equipment. Such an operation may pose a danger to a user who is uncomfortable with movement of the body.

상기한 단점을 해소하기 위하여 최근에는 수동식과 자동식 기립형 휠체어에 개발되고 있으며 수동식은 사용자의 인력이나 보호자에 의해 작동하는 방식으로 과도한 힘이나 불편함이 갖는 단점을 지니고 있다. 또한 기존의 전동식은 외산형으로 한국인의 체형에 맞지 않은 문제점이 있다.Recently, in order to solve the above disadvantages, manual and automatic standing wheelchairs have been developed, and the manual type has the disadvantage of having excessive force or inconvenience in the manner of operating by the user's manpower or guardian. In addition, there is a problem that the existing electric type is foreign type does not fit the body of the Korean.

본 발명은 상술한 종래의 문제점을 극복하기 위한 것으로, 본 발명의 목적은 휠체어 사용중 사용자가 작업을 위해 직립 할 수 있고 또한 직립된 상태에서 사용자의 안정성을 고려하여 기립후 지면과의 고정방식과 신체를 지지하는 이중 안전 장치로 된 전동 기립형 휠체어를 제공하기 위한 것이다.The present invention is to overcome the above-mentioned conventional problems, an object of the present invention is to allow the user to stand up for work during the use of the wheelchair, and also in the upright state in consideration of the user's stability after standing and fixing body with the ground To provide an electric standing wheelchair with a double safety device to support it.

이하 첨부된 도면을 참조하면서 본 발명에 따른 바람직한 실시예를 상세히 설명한다. 우선, 각 도면을 설명함에 있어, 동일한 구성 요소들에 한해서는 비록 다른 도면상에 도시되더라도 가능한 한 동일한 참조부호를 갖는다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in describing each of the drawings, the same components have the same reference numerals as much as possible even though they are shown in different drawings.

이하 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다. 우선, 본 발명을 설명함에 있어서, 관련된 공지기능 혹은 구성에 대한 구체적인 설명이 본 발명의 요지를 흐트릴 수 있는 경우 그 상세한 설명을 생략한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in describing the present invention, detailed descriptions of related well-known functions or configurations will be omitted if they may obscure the gist of the present invention.

도 1은, 본 발명에 따른 휠체어용 자동 기립장치를 나타낸 것으로, 작업용 휠체어의 구성부는 다음과 같이 구성된다. Figure 1 shows an automatic standing device for wheelchairs according to the present invention, the component of the working wheelchair is configured as follows.

상승 및 하강용 직선 구동장치와, 발판부 상승용 링크장치와, 전방 지면 지지용 고정바와, 링크식 등받이와, 하체 고정용 쿠션장치 및 제어부와 베터리등으로 구성된다.It consists of a straight drive device for ascending and descending, a link device for raising the footrest, a fixed bar for supporting the front ground, a link backrest, a cushioning device for controlling the lower body, a controller and a battery.

직립을 위한 구동장치인 직선 엑츄레이터(2)는 휠체어 중앙부에 위치하고 한 쌍의 링크 장치(4)의 움직임으로 동작된다. The linear actuator 2, which is a driving device for standing upright, is located at the center of the wheelchair and is operated by the movement of a pair of linkages 4.

이때 링크 작동은 엑츄레이터(2)가 일정거리(150mm)만큼 이동 되도록 구성되어 있어 최대 직립위치와 착상 위치가 항상 일정 하도록 되어 있다. At this time, the link operation is configured such that the actuator 2 is moved by a predetermined distance (150 mm) so that the maximum upright position and the implantation position are always constant.

직립을 위해 의자부(6)는 회전 최대각이 80도 이내로 움직이며, 등받이부(8)는 항상 지면과 수직하게 작동하도록 구성되어진다.For the upright chair 6 moves the maximum angle of rotation within 80 degrees, and the backrest 8 is always configured to operate perpendicular to the ground.

상기한 의자부 프레임(10)은 다리 받침 프레임(12)과 연결되어 직립 구동시에 링크 역할을 수행하며 그 역활은 좌,우의 발받침 바(bar)가 지면으로 내려오게 되어 캐스터를 지면으로부터 일정 간격으로 뜨게 한다. The chair part frame 10 is connected to the leg support frame 12 to perform a link role in the upright driving, the role of the left and right footrest bar (bar) is lowered to the ground to cast the caster a certain distance from the ground To float.

이러한 이유는 직립시 체중의 중심이 앞쪽으로 이동하게 되므로 사용자가 휠체어와 함께 쉽게 넘어질 수 있기 때문이다. This is because the center of the body weight is moved forward when standing up because the user can easily fall with the wheelchair.

따라서 발받이부(14)의 좌,우 바가 지면으로 내려와 체중 중심의 이동에 대한 지지점을 이동시키고 체중 중심을 휠체어 중앙에 놓이도록 하여 안정성을 확보하도록 하였다.Therefore, the left and right bars of the footrest 14 descended to the ground to move the support point for the movement of the weight center and to ensure the stability by placing the weight center in the center of the wheelchair.

사용자의 직립시 발판부 좌,우측의 바는 링크 작용에 의해 지면으로 내려와 지면과 밀착되며, 이로써 캐스터는 지면으로부터 떨어지게 된다. 즉 휠체어의 직립시에 주행이 불가능하도록 하였다. 이는 사용자의 안정성과 이력에 의해 넘어짐을 방지하고자 하였다.When the user stands up, the bars on the left and right sides of the scaffolding portion come down to the ground by the linking action and are in close contact with the ground, whereby the caster is separated from the ground. That is, it is impossible to drive when the wheelchair is upright. This is to prevent the fall by the user's stability and history.

또한 과하중 및 이물질 함입에 의해 부하가 발생하면 작용이 멈추도록 되어 있다. In addition, the action is stopped when a load occurs due to overload and foreign matter intrusion.

스위치는 누름 상태에서만 작동하도록 되어 임의의 일정 높이로의 조정이 가능하고, 위험 및 돌발 상황에서는 스위치를 때는 동작만으로 즉시 동작을 멈출 수 있도록 한다.The switch is operated only in the pressed state, so that it can be adjusted to a certain height, and in a dangerous and unexpected situation, the switch can be immediately stopped by simply operating the switch.

이상에서 상세히 설명한 바와 같이 본 발명은 휠체어 사용중 사용자가 작업을 위해 직립 할 수 있으며, 직립된 상태에서 사용자의 안정성을 고려하여 기립후 지면과의 고정방식과 신체를 지지하는 이중 안전 장치로 된 휠체어를 제공할 수 있는 것이다.As described in detail above, the present invention allows the user to stand up for work during the use of the wheelchair, and in consideration of the stability of the user in the upright state, the wheelchair is a double safety device supporting the body and the fixing method with the ground after standing. It can be provided.
