Description

Standing Wheelchair {Standing Wheelchair}

The present invention relates to a standing-type wheelchair, and more particularly, to a standing-type wheelchair that can be utilized for mobility and rehabilitation treatment of the elderly with reduced mobility or patients with lower extremity disabilities.

In general, a wheelchair refers to a chair with wheels so that a physically handicapped person or a person with reduced mobility can move while sitting.

These wheelchairs are mainly composed of a chair type, and as the user maintains a sitting state, it is accompanied by inconvenience in using residential facilities or convenience facilities installed in accordance with the physical conditions of normal people.

In addition, when used for a long time, such a chair-type wheelchair not only causes physical damage to body functions such as reduced exercise power of the lower body, decreased bowel function, and deterioration of blood circulation, but also has a risk of injury.

To this end, in Korean Patent Registration No. 10-2153835, as shown in FIG. 1, a main frame 11, an auxiliary wheel 12 provided at the lower front of the main frame 11, and the main frame 11 A main wheel 13 provided at the rear of the lower end, a seat frame 14 rotatably coupled to one point of the main frame 11, and a support frame rotatably coupled to one point of the main frame 11 (15), including a backrest frame 16 rotatably coupled to the seat frame 14 and the support frame 15 and a footrest frame !7 movably coupled to the main frame 11 And, the support frame 15 or the seat frame 14 is coupled to the main frame 11 and the shock absorber 18, and when the seat frame 14 stands in a direction perpendicular to the ground, the shock When the absorber 18 is extended and the seat frame 14 is seated in a horizontal direction with the ground, the shock absorber 18 is compressed.

These conventional standing-type wheelchairs allow users to more easily use residential facilities or convenience facilities installed in accordance with the physical conditions of normal people, helping the user to lead a daily life by himself, and standing up at the same eye level as others. It has the advantage of enabling smoother conversations by enabling communication.

However, these conventional standing-type wheelchairs have a problem in that they are not helpful for gait exercise for the elderly who can walk lightly and for gait rehabilitation for patients with temporary disabilities.

Accordingly, such a conventional standing-type wheelchair causes discomfort due to the user having to move from a standing-type wheelchair to another rehabilitation treatment device to receive rehabilitation treatment during gait rehabilitation treatment.

Republic of Korea Patent Registration No. 10-2153835 (Public date 2020.09.09.)

More preferably, in the standing type wheelchair according to the present invention, a pair of wires having one end attached to the knee support part and the other end attached to the abdominal support part and wire fixing parts each spanning the central part of the wire are installed on both sides of the wire to ensure the user's comfort. A buttock support for supporting the buttocks may be further included.

In addition, the gait guidance means can reciprocate the foot support part left and right alternately along the elliptical guide rails on both sides, respectively.

Meanwhile, the calf belt may include an electrical stimulation generating unit therein to provide a functional electrical stimulation (FES) treatment function to the user's calf.

In addition, the calf belt or the waist belt may include a massage means inside to provide a massage treatment function to the user's calf or waist.

As described above, the standing-type wheelchair according to the present invention helps a user with reduced mobility to lead a daily life by himself and enables smoother conversation by enabling communication at the same eye level with others in a standing state. However, since rehabilitation treatment can be performed while on board, the inconvenience of moving to a separate rehabilitation device during rehabilitation treatment can be eliminated.

In particular, the standing-type wheelchair according to the present invention not only provides a means of transportation for daily life to users such as the elderly and patients with temporary disabilities who have disabilities but can walk lightly, but also provides a continuous gait rehabilitation treatment function while riding for rehabilitation. effect can be maximized.
