本考案によれば、時間を要することなく容易な操作により折畳むことが可能であり、占有空間を著しく縮小することができる。 According to the present invention, it can be folded by an easy operation without taking time, and the occupied space can be remarkably reduced.

以下、図面を参照しながら、本考案の特徴や技術内容について、詳しく説明するが、それらの図面等は、参考や説明のためであり、本考案は、それらによって限定されるものではい。 Hereinafter, the features and technical contents of the present invention will be described in detail with reference to the drawings. However, the drawings and the like are for reference and explanation, and the present invention is not limited thereto.

図２と図３に示すように、本考案に係る車椅子１００は、両側に、それぞれ、連接座２０が設けられてあり、上記連接座２０に、背靠れ棒２１、シートクッション棒２２及びホイールフレーム２３が枢着され、背靠れ棒２１に、肘掛け棒２４が枢着され、肘掛け棒２４とシートクッション棒２２の先端が、支棒２５により一緒に枢着される。また、ホイールフレーム２３に、底棒２６と支持棒２７が枢着され、上記底棒２６とシートクッション棒２２の先端が、足踏み棒２８により一緒に枢着される。そして、支持棒２７の他端が、足踏み棒２８の上端に枢着され、また、二つの相対する連接座２０とホイールフレーム２３及び底棒２６に、相対する耳２０１、２３１、２６１が設けられ、連接座２０とホイールフレーム２３の耳２３１に、交差状第一可動フレーム３０が枢着され、ホイールフレーム２３と底棒２６の耳２３１、２６１に、交差状第二可動フレーム３１が枢着される。それから、二つの相対する背靠れ棒２１と足踏み棒２８の裏側にある耳２１１、２８１に、定位棒３２が枢着され、各相対する定位棒３２の他端が、係止ブロック３３内に枢着され、係止ブロック３３に係止されて固定される。 As shown in FIGS. 2 and 3, the wheelchair 100 according to the present invention is provided with connecting seats 20 on both sides, and the backrest rod 21, the seat cushion rod 22 and the wheel are connected to the connecting seats 20, respectively. A frame 23 is pivotally attached, an armrest rod 24 is pivotally attached to the backrest rod 21, and the tips of the armrest rod 24 and the seat cushion rod 22 are pivotally attached together by a support rod 25. Further, a bottom bar 26 and a support bar 27 are pivotally attached to the wheel frame 23, and the tips of the bottom bar 26 and the seat cushion bar 22 are pivotally attached together by a foot bar 28. The other end of the support bar 27 is pivotally attached to the upper end of the foot bar 28, and opposite ears 201, 231, and 261 are provided on the two opposite connecting seats 20, the wheel frame 23, and the bottom bar 26. The crossed first movable frame 30 is pivotally attached to the articulation seat 20 and the ears 231 of the wheel frame 23, and the crossed second movable frame 31 is pivotally attached to the ears 231 and 261 of the wheel frame 23 and the bottom bar 26. The Then, a stereotaxic bar 32 is pivotally attached to the ears 211 and 281 on the back side of the two opposing backrest bars 21 and the foot bar 28, and the other end of each opposing stereotactic bar 32 is placed in the locking block 33. It is pivotally attached and locked to the locking block 33 and fixed.

上記の構成要素からなる車椅子は、各要素が枢着されることになり、また、二つの相対する背靠れ棒２１と足踏み棒２８の後端に枢着された定位棒３２が、係止ブロック３３により係止されて固定されるため、背靠れ棒２１と足踏み棒２８が、回転できなくなり、各要素が固定される。 In the wheelchair composed of the above-described components, each element is pivotally attached, and a stereotaxic bar 32 pivotally attached to the rear ends of two opposing backrest bars 21 and foot bars 28 is locked. Since it is locked and fixed by the block 33, the backrest bar 21 and the foot bar 28 cannot be rotated, and each element is fixed.

本考案に係る車椅子１００を図４及び図５で示すように折畳む場合、背靠れ棒２１と足踏み棒２８との間に位置する係止ブロック３３を上方へ引くと、各定位棒３２と係止ブロック３３の係止が解消され、係止ブロック３３が上方へ引かれると同時に、各定位棒３２により、相対する背靠れ棒２１と足踏み棒２８とが、内側へ移動し、この時、図６〜図９に示すように、第一可動フレーム３０と第二可動フレーム３１は、各枢着点を利用して、連接座２０とホイールフレーム２３及び底棒２６が連動されて内側へ折畳まれる。同時に、ホイールフレーム２３と底棒２６が、枢着点を利用して、上方へ回転し、また、足踏み棒２８と支持棒２７が、枢着点を利用して、下方へ回転し、更に、支棒２５が連動されて外へ回転し、そのため、肘掛け棒２４も同時に下方へ回転する。そして、図１０で示すように、同時に、背靠れ棒２１が連動されて下方へ回転する。この時、背靠れ棒２１を下方へ押し合わせると、各要素が、その枢着点により、押し合わせられて定位される。このような構造により、車椅子１００の両側に設けられてある要素が押し合わせられ、占用空間が更に縮小される。 When the wheelchair 100 according to the present invention is folded as shown in FIG. 4 and FIG. 5, when the locking block 33 located between the backrest bar 21 and the foot bar 28 is pulled upward, The locking block 33 is unlocked and the locking block 33 is pulled upward. At the same time, the respective backrest bars 21 and the foot bar 28 are moved inward by the positioning bars 32. As shown in FIGS. 6 to 9, the first movable frame 30 and the second movable frame 31 use the pivot points to link the connecting seat 20, the wheel frame 23, and the bottom bar 26 to the inside. Folded. At the same time, the wheel frame 23 and the bottom bar 26 rotate upward using the pivot point, the foot bar 28 and the support bar 27 rotate downward using the pivot point, The support bar 25 is interlocked and rotated outward, so that the armrest bar 24 also rotates downward simultaneously. And simultaneously, as shown in FIG. 10, the backrest rod 21 is interlocked and rotates downward. At this time, when the backrest bar 21 is pressed downward, the elements are pressed and localized by their pivot points. With such a structure, the elements provided on both sides of the wheelchair 100 are pressed together, and the occupied space is further reduced.

また、図１１は、本考案の他の実施形態を示す図面であり、本考案によれば、定位棒３２は、係止ブロック３３が枢着される箇所に、互いに噛み合う定位歯３２１が設置され、これにより、より迅速に定位することができる。 FIG. 11 is a view showing another embodiment of the present invention. According to the present invention, the positioning rod 32 is provided with positioning teeth 321 that mesh with each other at a position where the locking block 33 is pivotally mounted. Thus, localization can be performed more quickly.

以上は、本考案のより良い実施形態を例示したものであり、本考案は、それによって限定されるものではない。従って、本考案に係わる実用新案登録請求の範囲や明細書の内容に基づいて行った等価の変更や修正は、全てが、本考案の実用新案登録請求の範囲内に含まれる。 The above is an example of a better embodiment of the present invention, and the present invention is not limited thereto.
