[0020] As illustrated in these drawings, the wheelchair according to the present invention, equipped with a waterproof section and a cold-weather section, comprises: a main body (100) equipped with an armrest section (110), a footrest (120), a seating section (130) on which a user can sit, and a backrest section (140); a plurality of wheels (200) rotatably installed on both sides of the main body (100) to enable movement of the main body (100); a waterproof section (300) installed on the upper part of the backrest section (140) to allow the user to avoid rain during rainy weather and to be selectively deployed and overlapped; and a cold-weather section (400) installed on the armrest section (110) and the footrest (120) to cover the user's hands and feet for warmth during the winter season.

[0021] Armrests (110) are installed on both sides of the main body (100) to support the user's arms, and a footrest (120) with a flat upper surface is provided on the lower front of the main body (100) so that the user's feet can be placed on it.

[0022] In addition, a seating portion (130) is provided in the center of the main body (100) so that a user can sit, and a backrest portion (140) is provided at the rear of the seating portion (130) so that the user's back can be supported.

[0023] The wheels (200) are rotatably provided on both sides of the main body (100) to enable movement of the main body (100) and serve to move the main body (100) to a desired position.

[0024] In addition, auxiliary wheels (210) are rotatably provided on both sides of the footrest (120) and are also provided to rotate, so that the direction of movement of the main body (100) can be changed when moving the main body (100).

[0025] Meanwhile, the waterproofing part (300) is installed on the upper part of the backrest part (140) so that the user can avoid rain during rainy weather, and serves to be selectively deployed and overlapped.

[0026] This waterproofing part (300) is configured to include a fixing part (310) that is fixed to one side of the upper part of the backrest part (140), a frame part (320) formed integrally with the fixing part (310) and having a plurality of frames (321) formed in a curved shape so as to be selectively unfolded toward the seating part (130) so as to be rotatably provided, and a bellows part (330) provided on the frame part (320) that unfolds together with the frames (321) when unfolded to shield the upper part of the seating part (130).

[0027] The fixing part (310) serves to selectively fix the waterproof part (300) to one side of the upper part of the backrest part (140), and for this purpose, the fixing part (310) is provided on the upper part of the backrest part (140) so as to be detachably attached to the frame (141) connecting the headrest.

[0028] This fixing part (310) is configured to include a fixing plate (311) which is open on one side and provided on the upper part of the backrest part (140) so as to be inserted to a certain depth into a frame (141) connecting a headrest, a pressure pin (312) which is provided to be retractable at the end of the open fixing plate (311) and presses one side of the frame (141) so as to maintain the state in which the fixing plate (311) is inserted into the frame (141), and an elastic spring (313) which elastically supports the pressure pin (312) so that the pressure pin (312) can press one side of the frame (141).

[0029] The fixing plate (311) is a plate-shaped member having a cut groove formed on one side of its surface so that it can be inserted into the frame (141) to a certain depth. It is preferable that the frame (141) and the cut groove be formed in a polygonal shape so that the fixing plate (311) does not rotate arbitrarily when inserted into the frame (141).

[0030] The pressure pin (312) is provided at the end of the open fixing plate (311) so as to be retractable and serves to press one side of the frame (141) so that the fixing plate (311) can be maintained in a state where it is inserted into the frame (141).

[0031] As described above, the structure for fixing the fixing plate (311) to the frame (141) can be such that the pressure pin (312) presses one side of the frame (141), but it can also be fixed by protruding the pressure pin (312) when the frame (141) is fully inserted into the cut groove and installing it across the entrance of the cut groove so that the pressure pin (312) catches on the frame (141).

[0032] It is effective to install the pressure pin (312) such that a portion is embedded inside the fixing plate (311) and the remaining portion is exposed outside the fixing plate (311), so that the user can grip it with their hand and remove it from the frame (141) forming the backrest (140).

[0033] The elastic spring (313) is installed in a form embedded inside the fixed plate (311) and is configured as a compression coil spring to elastically support the pressure pin (312) so that the joining pin (312) is pressed toward the frame (141).

[0034] The frame portion (320) is composed of a plurality of frames (321) that are fixed to one side of the fixed plate (311) and rotatably installed, and the plurality of frames (321) constituting the frame portion (320) are formed in a curved arch shape so that when unfolded, the waterproof portion (300) can be formed in a dome shape on the upper part of the seating portion (130).

[0035] By forming a dome-shaped waterproof section (300) by the frame section (320), water is prevented from accumulating on the surface of the waterproof section (300) during rain, thereby preventing the waterproof section (300) from being subjected to load, which increases durability.

[0036] It is desirable that the frame (321) constituting the frame part (320) be rotatably provided so that the frame (321) can be rotated to unfold or overlap each other, thereby allowing the installation and removal of the bellows part (330) to be selectively performed as needed.

[0037] The bellows section (330) is fixed to a plurality of frames (321) constituting the frame section (320) and forms a plurality of folds on the plate surface so that it can be selectively unfolded and overlapped, thereby allowing the waterproof section (300) to be selectively installed and removed on the upper part of the seating section (130).

[0038] It is desirable that the bellows (330) be formed of a material that does not absorb moisture so that it does not get wet even if exposed to moisture for a long time, and it is effective that the front area of ​​the bellows (330), which is located in front of the user when unfolded so that a field of view can be secured, be formed of a transparent material.

[0039] Meanwhile, the thermal insulation part (400) is installed on the armrest part (110) and the footrest (120) to provide warmth to the user during the winter season and serves to wrap the user's hands and feet.

[0040] This thermal insulation member (400) is configured to include a hand thermal insulation member (410) installed at the end of the armrest (110) to allow the user's hand to be inserted and wrapped, and a foot thermal insulation member (420) installed on the footrest (120) to allow the user's foot to be inserted and wrapped.

[0041] It is desirable to install the hand thermal insulation member (410) so as to be detachably attached to the end of the armrest (110) and the foot thermal insulation member (420) so as to be detachably attached to the upper surface of the footrest (120), thereby allowing the thermal insulation member (400) to be used by attaching it during the winter season when the temperature is low, and to remove it so as to store the thermal insulation member (400) separately during the summer season when the temperature is high.

[0042] These hand insulation members (410) and foot insulation members (420) can be attached to the armrest (110) and footrest (120), respectively, by various structures, but in the case of a wheelchair equipped with a waterproof and thermal insulation section according to the present invention, the hand insulation member (410) and foot insulation member (420) can be attached using Velcro tape (440).

[0043] It is effective to form one side of the hand insulation member (410) and foot insulation member (420) open so that the user's hand and foot can be inserted, and the remaining area closed so that when the user's hand and foot are inserted inside, the hand and foot are shielded from the outside, thereby providing insulation.

[0044] Additionally, the hand thermal insulation member (410) and the foot thermal insulation member (420) are formed from a warm material such as cotton or a sweater having a certain thickness or more for thermal insulation, and it is preferable that the outer surface be coated so that it is waterproof.

[0045] Additionally, the thermal insulation part (400) may further include a separate shielding cover (430) that can cover part of the upper body and the upper part of the lower body of the user while the user is seated on the seating part (130). It is effective to install such a shielding cover (430) so that it can be attached and detached by a separate Velcro tape (440) installed to wrap around the armrest part (110) so that it can be installed optionally.

[0046] The shielding cover (430) can be configured to cover the lower body and part of the upper body of the user, and can be changed into various shapes to cover the entire upper body area.

[0047] In addition, it is effective to form the shielding cover (430) with a warm material and coat its surface so that it can provide both thermal insulation and waterproofing.

[0048] The process of a user using a wheelchair equipped with a waterproof section and a cold-resistant section according to the present invention having such a configuration is as follows.

[0049] In case of rain, the fixing part (310) constituting the waterproof part (300) is used to insert the fixing plate (311) of the fixing part (310) into the frame (141) connecting the headrest, which is provided on the upper part of the backrest part (140), and then the frame (141) is pressed using a pressure pin (312) so that the waterproof part (300) is installed on the upper part of the seating part (130).

[0050] In this state, the plurality of frames (321) constituting the frame portion (320) of the waterproof portion (300) are rotated so that the bellows portion (330) attached to the frame (321) is unfolded, thereby shielding the upper part of the attachment portion (130) from the outside so that rainwater does not fall on the wheelchair user.

[0051] And, in the winter season, the hand insulation member (410) and foot insulation member (420) constituting the insulation part (400) are installed on the armrest part (110) and footrest (120) respectively using Velcro tape (440), and then the user's hands and feet are placed inside the hand insulation member (410) and foot insulation member (420) to provide warmth, thereby allowing the wheelchair to be used conveniently without discomfort due to the cold in the winter season.

[0052] Additionally, if necessary, a shielding member (430) can be installed using Velcro tape (440) to cover the user's lower and upper body, allowing the wheelchair to be used in a warmer condition.

[0053] A wheelchair equipped with a waterproof section and a cold-resistant section according to one embodiment of the present invention having the configuration described above can be used safely and conveniently while maintaining the user's body temperature even in cold winter or rainy weather, thereby increasing user convenience and improving stability when operating the wheelchair.
