Description

  The present invention relates to a wheelchair, and more particularly, to a wheelchair in which each part constituting the wheelchair is configured independently, the angle can be adjusted, and the structure is convenient for replacement.

  About the structure which concerns on the frame adjustment apparatus of the wheelchair developed conventionally, the basic form is similar to the traditional structure, and no big change is seen. Therefore, there are some that can be partially adjusted, but it can be said that there are few things that can be changed efficiently according to the body shape of the user with respect to the overall structure. Moreover, the position of the general armrest frame cannot be changed during use because of its structure in relation to the member to be used. Some are configured to connect a specially structured member to the back frame for rotation, disassembly and storage. For example, a pipe-type pedal is connected to a wheel frame so as to be rotatable, and can be rotated, disassembled and stored and can be adjusted in level, but is not comfortable to use. The seat pad is fixed on the wheelchair frame with an adhesive pad. A plurality of sleeve-type support rods are fixed to the wheel frames on both sides. Such a structure can adjust the width of the seat, but does not have the function of disassembling and storing the wheelchair.

  Conventionally, various types of wheelchairs have been developed. However, any type of wheelchair has many inconveniences because its form cannot meet different needs for adjusting to the body shape of the individual in use. . Moreover, disassembling is not easy, and the cost is more than necessary for disassembling. Therefore, the cost for maintenance is high, and the coupling of some members is unstable. For example, a fixed seat for a guard member that holds the body uniformly needs to have both functions of turning and rolling. There are problems in use, such as

  Therefore, the problem of the present invention is that various adjustments can be made according to the needs of the user, convenience in use and safety can be improved, and replacement of some members is convenient, and the service life is shortened.
