以下、本考案キャスター、背負い台、椅子機能一体折り畳み装置の実施例を図 面に基づいて説明する。 先ず、図１が示すのは、本考案の立体組立図で、コの字型のハンドル１１（左 右両端にそれぞれ掛鉤１１２が成形される。）が、一対の相対式掛合部品１２に よって背もたれ布１３１をかけた車体本体の上支持体１３を支え、つまみネジ１ ４を締める。この外、車体本体の下支持体１５（シート布１５１を被せる）は、 組合せ部品１５２と上支持体１３によって直角に交差し、左右両端にはそれぞれ 可動する係止部品１６が設置され、更に車輪部品１７(左右各一組)にはブレーキ 部品１８が設置され、固定具１９(図５参照)によって適時車体を動かないように する。   The following is an example of an embodiment of the present invention caster, backrest, and chair function integrated folding device. It will be explained based on the plane.   First, FIG. 1 is a three-dimensional assembly drawing of the present invention, in which a U-shaped handle 11 (left Hooks 112 are formed on both right ends. ) On the pair of relative engaging parts 12 Therefore, support the upper support 13 of the vehicle body with the backrest cloth 131, and set the thumbscrew 1 Tighten 4. In addition to this, the lower support 15 (covering the sheet cloth 151) of the vehicle body is The assembly part 152 and the upper support 13 intersect at a right angle, and the left and right ends are respectively crossed. Movable locking parts 16 are installed, and brakes are added to the wheel parts 17 (one set each on the left and right). The parts 18 are installed, and the fixtures 19 (see FIG. 5) prevent the vehicle body from moving in a timely manner. To do.

【０００６】 図２Ａに示すのは、相対式掛合部品１２とその枢設部品(ハンドル１１と上支 持体１３)の立体図である。図で見るとおり、歯型式が相互に密接する相対式掛 合部品単品１２１，１２２の二つを採用し、それは歯型構造１２３、１２４が設 置される他、ハンドル１１及び上支持体１３を向いている側の端面は凹槽構造１ ２５、１２６になっており、この外二つの相対式掛合部品単品１２１，１２２の 軸芯点にはそれぞれバネ１２７が設置され、ネジ桿１２８とつまみネジ１４を上 支持体１３及びハンドルの穿孔１３２，１３３、１１１に合わせ、相対式掛合部 品１２をハンドル１１及び上支持体１３に設置して一体にし、つまみネジ１４を 緩んだ状態にしておき、間接的に相対式掛合部品１２を回し、その単品１２１、 １２２を接続状態にし、更にハンドル１１を回転させて使用者が適する位置にす る。[0006]   FIG. 2A shows the relative engagement part 12 and its pivotal parts (the handle 11 and the upper support). It is a three-dimensional view of holding body 13). As you can see in the figure, the relative type hooks whose tooth types are closely Two combined parts, 121 and 122, are adopted, which have the tooth type structures 123 and 124. In addition to being placed, the end surface on the side facing the handle 11 and the upper support 13 has a concave tank structure 1 25 and 126, of which the other two relative type engaging parts 121, 122 A spring 127 is installed at each of the shaft center points, and the screw rod 128 and the thumbscrew 14 are moved upward. Aligning the support 13 and the perforations 132, 133, 111 of the handle, the relative engagement part Install the product 12 on the handle 11 and the upper support 13 and integrate them, and attach the thumbscrew 14 Leave it loose and indirectly turn the relative engagement part 12 to 122 is connected, and the handle 11 is further rotated to a position suitable for the user. It

【０００７】 図３は図２の立体組立図であって、相対式掛合部品１２がしっかり締結した状 態にあるが、形態を変えたい場合、つまみネジ１４を緩めて目的を達する。同時 に単品式の掛合部品は相互に噛み合うため、密接度が高く、安全性が高い。[0007]   FIG. 3 is a three-dimensional assembly drawing of FIG. 2, in which the relative engagement parts 12 are firmly fastened. However, if you want to change the shape, loosen the thumbscrew 14 to achieve the purpose. simultaneous In addition, since the single-piece engagement parts mesh with each other, the closeness is high and the safety is high.

【０００８】 図４に示すのは車体本体の下支持体１５に枢設する組立部品の立体組立図で、 上支持体１３(図中指示)と組合せ部品１５２によって接続し、更にこれらと垂直 に交差する下支持体１５は、本体にシート布１５１を被せる他、左右両端にそれ ぞれ係止部品１６を図の矢印方向に回動可動に設置して車体を立たせた状態とし 、或いは可動式の構造であるので、車体と平行に内縁に収容することができる。 この外下支持体１５下方の車輪部品１７付近には、一組のブレーキ部品１８(ブ レーキレバー１８１が設置される)、固定具１９が設置され（図５参照）、下支 持体１５に設けられた固定具１９に連結され、ブレーキ部品１８の軸桿２０付近 の凸桿２１に引っ掛ける。これによって更に車体本体が安定する。図中の固定具 １９には鉤状構造２２が成形され、凸桿２１に係合する。[0008]   FIG. 4 is a three-dimensional assembly drawing of the assembly parts pivotally mounted on the lower support 15 of the vehicle body. It is connected to the upper support 13 (indicated in the figure) by a combination part 152, and is also perpendicular to these. The lower support 15 that intersects with the main body is covered with the sheet cloth 151, and the left and right ends are Each of the locking parts 16 is rotatably mounted in the direction of the arrow in the figure to bring the vehicle upright. Alternatively, since it has a movable structure, it can be accommodated in the inner edge parallel to the vehicle body. A set of brake parts 18 (blocks) is provided near the wheel parts 17 below the outer lower support 15. The rake lever 181 is installed), the fixture 19 is installed (see FIG. 5), and the lower support Around the rod 20 of the brake component 18, which is connected to a fixture 19 provided on the holding body 15. Hook on the convex rod 21 of. This further stabilizes the vehicle body. Fixture in the figure A hook-shaped structure 22 is formed on 19 and engages with the protruding rod 21.
