FIG. 3 is a perspective view of a seat of a wheelchair according to an exemplary embodiment of the present invention, 4 is a view showing a state in which a multifunctional plate of a wheelchair is turned forward according to an embodiment of the present invention, and FIG. 5 is a view showing a state in which a multifunctional plate of a wheelchair according to an embodiment of the present invention is moved rearward And the backrest is separated from the backrest.

1 and 2, the wheelchair includes a seat 100, a multifunctional plate 200, a plate support 210, and a back 300.

The seat 100 is connected to the backrest 300 to support and support the user's hips and thighs and to have a flat shape for protection. Although not shown in the figure, an arm rest and a foot rest that allow the user to normally lean his / her arms and feet on the outside of the seat 100, and a front wheel and a rear wheel that allow the wheelchair to be moved, have. In this case, the rear wheel must have a size larger than a predetermined size so as to be able to be held by the user, and the front wheel is preferably formed to have a size smaller than that of the rear wheel to be used as an auxiliary device for driving the wheelchair in accordance with the rear wheel. Further, the seat 100 can be used in accordance with the convenience of the user, such as leather, synthetic fiber, and plastic, without limitation of the material.

The multifunctional plate 200 is provided at a lower portion of the seat 100 and is rotatably coupled to the front end of the seat 100 so as to be able to unfold the user's leg, And is rotatable in the rearward direction.

6, the shape of the multifunctional plate 200 is such that the lower portion of the multifunctional plate 200 is extended in a '-' shape so as to support the user's body in a side-by-side relation with the seat 100 at the time of rotation, Or the like.

In addition, there is no limitation on the material such as the seat 100 as in the seat 100, but it is preferable that the frame is made of a lightweight but hard titanium alloy or a carbon alloy in consideration of convenience in turning.

At this time, the multifunctional plate 200 is provided with a pair of first fixing grooves 220 opposed to the left and right sides of the front side so that the seat 100 and the multifunctional plate 200 are rotatably coupled, And a fixing plate 110 is fixed to both sides of the seat 100 in accordance with the number of the first fixing groove 220 and the second fixing groove 230, The fixing plate 110 includes a first fixing hole 111 formed to correspond to each of the first fixing grooves 220 and a second fixing hole 112 formed corresponding to each of the second fixing grooves 230, .

Here, the first fixing nail 240, which passes through each of the first fixing holes 111 and is detachably coupled to each of the first fixing grooves 220, The multifunctional plate 200 may further include a second fixing nail 250 detachably coupled to the groove 230 so that when the first fixing nails 240 are separated from each other, And the first fixing nails 240 can be pivoted about the center axis when the second fixing nails 250 are separated from each other. At this time, the fixing plate 110, the first fixing nails 240, and the second fixing nails 250 may be formed of the above-mentioned titanium niobium (Nb 2 O 3) so as to sufficiently bear the weight of the multifunctional plate 200, Alloy, carbon alloy, or the like.

 A plurality of plate supports 210 are accommodated in the upper portion of the multifunctional plate 200 through the receiving grooves 260 formed in a predetermined size. At this time, the upper end of the plate support 210 is rotatably coupled to the receiving groove 260, and a wheel is formed at the lower end of the plate support 210. When the plate 200 is rotated forward or backward, So that the multifunctional plate 200 can be supported with respect to the ground, and the wheelchair can be moved even in the rotated state. At this time, the length of the multifunctional plate 200 should be formed so that the wheel formed at the lower portion thereof is supported with respect to the ground, in parallel with the front wheel and the rear wheel of the wheelchair.

The backrest 300 is connected to a slope having an angle perpendicular to the seat 100 or any angle between 91 and 110 degrees to support and protect the back and back of the user. The seat 100 is detachably attached to the seat 100. The seat 100 is detached in a state where the multifunctional plate 200 is rotated in the rearward direction. The seat 100 is formed with an engagement pin 310 extending from the lower end of the seat 100, A coupling groove 140 is formed corresponding to the pin 310 so that the backrest 300 and the seat 100 are detachably coupled.

At this time, although not shown in the drawing, a headrest for protecting the user's neck and head and a ringer rest for resting the ringer can be additionally formed on the upper part of the backrest, It can be used for the user's convenience such as leather, synthetic fiber, and plastic.

As described above, it is to be understood that the technical structure of the present invention can be embodied in other specific forms without departing from the spirit and essential characteristics of the present invention.

Therefore, it should be understood that the above-described embodiments are to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than the foregoing description, All changes or modifications that come within the scope of the present invention should be construed as being included within the scope of the present invention.
