  A windproof rain cover for a wheelchair according to claim 1 of the present invention includes one fixed portal frame made of synthetic resin (hereinafter referred to as a fixed frame) located on the backrest seat side of the wheelchair, and the fixed frame. It consists of a plurality of rotatable portal-shaped frames (hereinafter referred to as a rotatable frame) made of synthetic resin located on the front side (the front side in the traveling direction of the wheelchair). With these frames attached to the wheelchair, the pins that support both ends of each rotatable frame are deployed in the shape of a fan as viewed from the side of the wheelchair, with the pins supporting the pivots as the center of rotation. It can be folded and converted into an open state. A protective cover can be detachably attached to at least the unfolded frame.

  Further, both end portions of the fixed frame are fixed, and both end portions of the rotatable frames are pivotably connected in the forward and backward directions of the wheelchair. Pin positions for pivoting the both ends of each rotatable frame such that both ends of each rotatable frame are in contact with each other in a state of being fan-shaped when viewed from the side of a wheelchair and the deployment angle is limited. Is set. Projections for removably connecting to the mounting portion are formed on the lower surfaces of the pair of support portions, the mounting portions being attached to both side frames for a backrest seat of a wheelchair, and the pair of support portions An insertion port is formed to removably couple the protrusion provided on the.

  With such a configuration, since each of the frames is formed of a synthetic resin, it is lightweight and can be easily attached to and detached from a wheelchair even by a woman or an elderly person. Moreover, it has a function which regulates an expansion | deployment angle because the both-ends edge part of each said rotatable frame provided adjacently contact | abuts. Thereby, the unfolding angle of each said rotatable frame can be controlled with a simple structure.

  In the windproof rain cover for wheelchair according to claim 2 of the present invention, the shaft center of the insertion port is more than the shaft center of the both side frames in a state where the mounting portion is attached to both side frames for the backrest seat of the wheelchair. It is formed to be inclined in the backward direction of the wheelchair. If comprised in this way, since the said fixed frame is located in the back side from the both-sides frame for the backrest seats of a wheelchair, it can protect a patient's whole body. Further, although the center of gravity of the entire frame is ahead of the axis of the insertion port, the frame can be prevented from falling forward due to its own weight, so that the connection between the mounting port and the protrusion can be stabilized.

  In the windproof rain cover for wheelchair according to claim 3 of the present invention, the cross-sectional shape of the insertion opening of the mounting portion is rectangular. Moreover, it can replace with a rectangle and the same effect can be acquired also as a square, a triangle, a polygon, or an ellipse. With such a configuration, it is possible to prevent the support portion from rotating about the axial center of the mounting portion even when the support portion of the windproof rain cover is subjected to wind pressure such as strong wind.

  In the windproof rain cover for wheelchair according to claim 4 of the present invention, the mounting portion is divided into two or more insertion openings. With such a configuration, a plurality of wind and rain covers can be inserted. For example, a windproof rain cover and an awning cover can be inserted and used at the same time.

  The windproof rain cover for wheelchair according to claim 5 of the present invention is a protective cover that is transparent, translucent, or a sun protection cover using an ultraviolet shielding sheet or the like to protect the upper part of the head of the seated person from sunlight. It is said. With such a configuration, an appropriate protective cover can be attached according to the season, the weather, or the needs of the care recipient, so that a windproof rain cover adapted to the situation of the care recipient can be applied. .

  A windproof rain cover for a wheelchair according to claim 6 of the present invention includes a snap fastener, a hook-and-loop fastener, a string or the like as a connecting tool that the protective cover is detachably attached to the fixed frame and the rotatable portal frame. Is provided. With such a configuration, the cover can be easily and quickly detached from the frame.

  The windproof rain cover for a wheelchair according to the present invention is lightweight because each frame is formed of a synthetic resin, and can be easily attached to and detached from a wheelchair even by a woman or an elderly person. In addition, since each frame bends in the width direction, even if the distance between the frames on both sides for the backrest seat is slightly different (about 4 cm), the frame can be attached by expanding and contracting the width between the frames.

  Since the support portion has a function of regulating the deployment angle by abutting both end edges of the respective rotatable frames provided adjacent to each other, the deployment angle of each of the rotatable frames can be simply structured. Can be limited. Further, since the attachment portion is inclined in the retracting direction of the wheelchair with respect to the axis of the gripping portion attached to the both side frames for the backrest seat of the wheelchair, the frame is moved forward by its own weight. It is possible to prevent the mounting part and the support part from being connected and held stable.

  Since the cross-sectional shape of the insertion opening of the attachment portion is rectangular, the support portion can be prevented from rotating around the axis center of the attachment portion due to wind pressure such as strong wind. Moreover, if the insertion port of the said attachment part is divided into two or more, for example, a wind-proof rain cover and a sunshade cover can be utilized simultaneously.

  Since the frame frame of the frame portion is provided with a protective cover made of a foldable material, when the protective cover is soiled, it can be easily removed and replaced with a new one. The protective cover is transparent, translucent, or a sunshade cover using an ultraviolet blocking sheet to protect the upper part of the seated person's head from sunlight. Thereby, since a suitable protective cover can be put on according to the season, the weather, or the patient's request, the windproof rain cover according to the patient's situation can be applied. Furthermore, since a snap fastener, a hook-and-loop fastener, a string, or the like is provided as a connector for detachably attaching the protective cover to the fixed frame and each rotatable frame, the cover can be easily and quickly removed from the portal frame. Detachable.

In FIG. 6, the attachment portion 4 is divided into two parts by sandwiching and attaching an insertion port 41 for detachably inserting the protrusion 34 provided on the support portion 3 and both side frames 80 for a backrest seat of the wheelchair C. The grip portion 42 and the connecting portion 43 that connects the insertion port 41 and the half of the grip portion 42 are integrally formed. Since the attachment portion 4 requires mechanical strength, weather resistance, water resistance, and the like for holding the frame portion 2 and the support portion 3, it is desirable that the attachment portion 4 be formed of stainless steel, aluminum alloy, or the like.

  Since the pipes are generally used for the both side frames 80 for the backrest seat of the wheelchair C, the grip portion 42 is a half grip piece (semicircular or arc shape), and one piece 42a is the connecting portion. 43 and the half piece 42b are fastened by a butterfly bolt (not shown) or the like with the frame 80 in between. In addition, since the both side frames 80 of the wheelchair C are pipe-shaped, there is a possibility that the grip portion 42 may rotate about the axial center of the both side frames 80 due to wind pressure or the like. For this reason, it is desirable that an anti-rotation packing (not shown) is provided on the inner peripheral portion of the clamping portion 42. Note that silicon or the like can be used as the material of the anti-rotation packing.

  The axis of the insertion port 41 is inclined 20 ° to the rear side in the traveling direction of the wheelchair C with respect to the axis of the grip portion 42. This inclination angle is desirably 10 ° to 20 °. When the inclination angle is 10 ° or less or 20 ° or more, the stability of holding the support portion 3 is lowered.

The protective cover 5 is integrally formed so as to cover the entire frame portion 2 and is detachably attached by a connecting tool 6 described later. In addition, in order to protect the waist and feet of the care recipient from storms and ultraviolet rays, a protective cover extends from the frontmost rotatable frame 22c and hangs down. The protective cover 5 is required to be transparent because it is desirable that the protective cover 5 be visible to the care recipient. Moreover, since the flexibility which can be folded is also required, it is desirable to use a highly transparent vinyl chloride sheet. However, it is also possible to use various transparent or translucent synthetic resin sheets having similar properties. Moreover, in order to block the ultraviolet rays irradiated to the seated person, a part or all of them may be made translucent or opaque (including coloring), or an ultraviolet shielding sheet may be used.

  As shown in FIGS. 9 (a) and 9 (b), snap fasteners, hook-and-loop fasteners, strings, or the like are attached as connecting tools 6 at two upper portions of each frame portion, and the protective cover 5 is attached to and detached from the frame portion.
