Description

Wheelchair for easy getting on and off

The present invention relates to a wheelchair, and more particularly, to a wheelchair that allows a patient to easily get on and off the wheelchair with small movements in a sitting position.

In general, a wheelchair is used as a means for a guardian to help a patient with inconvenient lower extremities move on their own, or for a patient who has difficulty walking due to paralysis or deterioration of general condition.

Such a wheelchair is a chair-type movement mechanism in which wheels are installed so that a person with reduced mobility can move in a seated state, and has a seat, a backrest, and a footrest on a frame, and has a structure in which wheels are mounted on the front and rear.

Wheelchairs are generally used in a way that the user directly manipulates the wheel handle and brake. Recently, electric wheelchairs that electronically control all driving movements such as steering and speed by mounting an electric motor or artificial intelligence technology are applied. Robotic wheelchairs are also being actively developed.

On the other hand, in order to move the patient with difficulty in mobility, they get on a wheelchair with the help of a guardian or helper and then move. In addition, after the patient moves, the help of a helper is needed to get the patient out of the wheelchair. However, in the case of a seriously ill patient who is very difficult to move, a lot of effort from a helper is required because it is done in a state that completely depends on the weight of a guardian or a helper in order to get on or off the wheelchair.

Korean Patent Publication No. 10-2007-0098777 discloses a wheelchair that is easy to get on and off.

And Korean Patent Publication No. 10-2020-0057977 discloses a wheelchair having a boarding function. The posted wheelchair includes: a body integrally provided with a base frame for mounting a wheel, and a back frame vertically formed at a predetermined height from the rear upper side of the base frame; a main seating part mounted horizontally at a predetermined height from the base frame in front of the back frame; and an auxiliary seating part mounted to drive up, down, forward, and backward from the main seating part at the front of the back frame to enter and exit the vehicle seat upper side.

The posted wheelchair is provided with an auxiliary seating unit that is driven up and down in the front and rear directions from the main seating unit, but in order for a patient with poor mobility to sit in the auxiliary seating unit, a lot of help from a helper as in the prior art is needed.

In particular, the patient uses a wheelchair when moving from the bed to the toilet to urinate, but there is a difficulty in moving the patient from the wheelchair to the toilet after moving a short distance.

A toilet bowl is installed so that The toilet bowl may be supported by a toilet bowl support frame coupled to the first and second seat frames 50 and 60 .

The operation of the wheelchair for easy getting on and off according to the present invention configured as described above will be described as follows.

1 and 5, in order to move a patient who is uncomfortable sitting on a bed or toilet seat, the wheelchair 10 according to the present invention is first moved to the front of the patient, and then to the first and second seat frame coupling parts 70. The coupling state of the first and second seat frames by That is, the coupling is performed from the coupling hole 74 formed in the first seat frame 50 and the bracket 72 rotatably installed at the end side of the second seat frame 60 and having an insertion part into which the first seat frame is inserted. After the pin 73 is removed, the first and second seat frames 50 and 60 are rotated outwardly.

In this way, the first and second seat frames 50 and 60 move in the direction in which the first and second elevating support parts 51 and 81 coupled to the first and second main posts 20 and 30 are spread as a center. will rotate to

In this state, the wheelchair 10 is battery operated so that the left and right seat parts 41 and 42 are positioned on both sides of the hip of the patient. At this time, the left seat part 41 and the right seat part 42 should be positioned at substantially the same height as the upper surface of the bed on which the patient sits or the height of the toilet seat.

And while moving the hip of the patient, the first and second seat frames 50 and 60 are rotated in a direction to be coupled to each other so that the left and right seat parts 41 and 42 are positioned under the hip of the patient. In this way, the patient is seated on the seat portion 40 formed by the left and right seat portions 41 and 42 .

When the patient sits on the seat part 40, the ends of the first and second seat frames 50 and 60 are coupled using the first and second seat frame coupling parts 70.

When the first and second seat frames 50 and 60 are coupled by the first and second seat frame coupling parts 70, press the pedal of the working fluid supply part 85 of the lifting unit 80 to remove it. By supplying hydraulic oil to the first and second cylinders 81 and 82, the first and second lifting support parts 51 and 61 are raised with respect to the first and second main posts 20 and 30. Therefore, the seat part on which the patient sits is separated from the upper surface of the bed or the toilet. In this state, the helper or guardian grabs the handle portions 55 and 65 and moves the wheelchair on which the patient sits to the movement position of the patient.

And the first and second seat frames 50 and 60 are lowered by using the lifting means at the moving position of the patient, and the first and second sheets combining the ends of the first and second seat frames 50 and 60 After releasing the coupling force by the frame coupling part 70, the first and second seat frames 50 and 60 are rotated in the outward direction of the patient, so that the left and right seat parts can be separated from the hip of the patient. You can get off the wheelchair.

As described above, the wheelchair that is easy to get on and off according to the present invention can sit on or off the seat of the wheelchair with minimal movement while the patient is seated, so it is easy for the patient with difficulty in movement, and thus the behavior of the guardian or helper Efforts associated with the movement of this uncomfortable patient can be minimized.

Although the present invention has been described with reference to the embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention will have to be determined by the technical spirit of the appended claims.
