請求項１の実施の形態について説明する。
【０００９】
台車ａの前側の向きに左右夫々のハンドル２を回動し、車台ａの前側左右の支承筒３に左右が分離されたハンドル２の基部２'を弾圧機構４により支承筒３に回り止状態に固定する回り止機構５により夫々のハンドル２の基部２'を支承筒３に固定せしめた後、台車ａに荷物を載置して左右のハンドル２を引きながら運搬する。
【００１０】
不使用時には弾圧機構４により支承筒３に回り止状態に固定する回り止機構５の作用を解除し、左右のハンドル２の向きを前側の向きから後側の向きに回動して再び弾圧機構４により回り止状態に固定する回り止機構５によりハンドル２の基部２'を支承筒３に固定し、該リヤカータイプの運搬車の長手方向の長さを縮小して格納する。
【００１１】
また、常態では台車ａの中央の前後方向に架設した縦桟８と、台車ａの左右端に設けた左縦桟 15 と右縦桟 16 とが前後の左分断横桟 10 ，右分断横桟 11 を介して軸受片９により軸着連結され、且つ左縦桟 15 と右縦桟 16 若しくはその連結部材とが前後の左折曲支持桟 13 ，右折曲支持桟 14 を介して軸受突片 12 により軸着連結されて縦桟８，左縦桟 15 ，右縦桟 16 とが平面平板状態で展開されて保持されるので、この台車ａに荷物を積載し、引きハンドルｂを引き乍ら運搬する。
【００１２】
リヤカータイプの運搬車を折り畳むときは、縦桟８を上方に持ち上げると、左縦桟 15 ，右縦桟 16 の前後に軸着した左右の分断横桟 10 ， 11 及び左右の折曲支持桟 13 ， 14 が軸受片９，軸受突片 12 の軸着部を回動中心として回動し、左右の縦桟 15 ， 16 が相互に接近して台車ａが略く字状に折り畳まれ、台車ａを縦二つ折りに折り畳み、リヤカータイプの運搬車の巾方向の長さを縮小した後、左右のハンドル２の基部２ ' を弾圧機構４による回り止機構５の作動を解除して左右のハンドル２の向きを前側の向きから後側の向きに回動し、再び弾圧機構４による回り止機構５の作動によりハンドル２の基部２ ' を回り止状態に固定してリヤカータイプの運搬車の長手方向の長さを縮小して格納する。
【００１３】
請求項２の実施の形態について説明する。
【００１４】
左右のハンドル２に連結ハンドル６を固定具７により着脱自在に固定したため、常態では左右のハンドル２が連結ハンドル６により確固に固定されるので、左右のハンドル２の間に入ってハンドル２を引きながら運搬する。
【００１５】
不使用時には固定具７を解除して連結ハンドル６を左右のハンドル２より外し、夫々のハンドル２の基部２'弾圧機構４により回り止状態に固定する回り止機構５の作用を解除し、左右のハンドル２の向きを前側の向きから後側の向きに回動して再び弾圧機構４により回り止状態に支承筒３に固定する回り止機構５とによりハンドル２の基部２'を支承筒３に回り止状態に固定する。

【００２７】
図示した実施例ではこのリヤカータイプの運搬車（以下単に運搬車という）の荷台ｃは左右の縦桟15，16間の巾方向の中央に配設した縦桟８の前後端に下方に開口部を有するチャンネル形状の軸受片９，９を溶接し、この前後の軸受片９，９に夫々左右の分断横桟10，11の基部を軸着ボルト29にて夫々の分断横桟10，11の基部上面が軸受片９の天井板の下面に接するように軸着する。
【００２８】
この前後左右の分断横桟10，11の他端を左右に延設し、この延設端にコ字状の枢着片を設け、この枢着片に対応する左右の縦桟15，16に対応枢着片を設けて軸着ボルト30にて両者を軸着する。
【００２９】
前記前後の左右の分断横桟10，11間に複数個（図では各二個）の補助縦桟31と端部縦桟32を架設して荷台ｃを平板状の左右に分割された分割荷台ｃ'，ｃ'に構成する。
【００３０】
上記前後の軸受片９の外側の垂設片の下端に鉤型の軸受突片12を連設し、この軸受突片12の左右に支点33，33を設け、左右の縦桟 15 ， 16の前後の軸着ボルト30の下方の対応軸着片に支点34を設け、この支点34と前記支点33間に左折曲支持桟13，右折曲支持桟14を架設してその両端部を軸着してリンク機構を構成し、このリンク機構を前記バー29・30（左右の分断横桟の長さ）＝バー33・34（左右の折曲支持桟の長さ），バー29・33（軸着ボルトと支点間の距離）＝バー30・34（軸着ボルトと支点間の距離）に構成して並行クランク機構35を形成する。
【００３１】
尚、前記荷台ｃの主要構成メンバーを軽量で強靭な断面矩形形状のアルミニウム合金中空引抜長尺材で形成し、この長尺材を適宜切断して荷台ｃを構成する。
【００３２】
また図中符号36は左右の縦桟15，16上に立設し、荷台ｃの積載容積を増大するとともに左右の縦桟15，16の曲げに対する強度を付加するサイドフェンス，37はタイヤ車輪１の前後側部を取り巻くように架設し、左右の縦桟15，16の横方向の曲げに対する強度を補強する車輪ガイド，38，39は左右のサイドフェンス36の前後にヒンジ部材を介して突っ張り状態に掛け渡し架設し積載荷物の落下を防止し、且つ台車ａの剛性を高める荷止めフェンス，符号40は荷物を台車ａに積み降ろしするとき、荷台ｃを左右のタイヤ車輪１と協動して台車ａを安定した姿勢で地上に定置するＵ状脚で、いずれもアルミニウム合金長尺引抜パイプを適宜切断して製作する。
【００３３】
本実施例を上記のように構成したので、常態では左右のハンドル２の基部に設けた回り止片 25 が回り止機構５の前側の切り込み溝 24 に係止され、この係止状態を弾圧機構４のスプリング 23 の付勢力により固定するのでハンドル２は台車ａ上の左右に前側向きで固定される。
【００３４】
ハンドル２の基部２ ' を弾圧機構４のスプリング 23 の付勢力に打ち克って下方に押動すると、回り止片 25 が基部２ ' と一緒に下方に移動し、回り止片 25 と前側の切り込み溝 24 との係合が解除するのでハンドル２を台車ａの後側向きに 180 °回動して手を離すとスプリング 23 の付勢力で回り止片 24 が後方の切り込み溝 24' に係合してその位置で固定される。
【００３５】
また、左右のハンドル２，２に連結ハンドル６の両端部を嵌入して固定具７の蝶ボルト 27 ， 27 で両者を固定すると、左右のハンドル２は連結ハンドル６により確固に連結され、不使用時にはこの固定具７を弛めに連結ハンドル６を左右のハンドル２より取り外す。
【００３６】
また、常態では左右の分断横桟 10 ， 11 の基部の上面が軸受片９の天井板の下面に当接し、分断横桟 10 ， 11 の他端がタイヤ車輪１を介して左右の縦左右 15 ， 16 に軸着ボルト 30 で軸着保持され、且つ左右の分断横桟 10 ， 11 ；左右の折曲支持桟 13 ， 14 の各メンバーを並行クランク機構 35 に構成したので左右の折曲支持桟 13 ， 14 もまた係止状態で保持されるので、左右の分割荷台ｃ ' ，ｃ ' は左右の縦桟 15 ， 16 間に平面平板状態に展開された荷台ｃとして保持される。
【００３７】
また、左右のサイドフェンス 35 の前後に荷止めフェンス 38 ， 39 を突っ張り状態に掛け渡すことにより荷台ｃを確固に平板状態に展開して保持することができる。
【００３８】
この荷台ｃ上に荷物を載置して運搬する。
【００３９】
運搬車を折り畳むときは、縦桟８を上方に持ち上げると、左右の分断横桟 10 ， 11 の基部上面と軸受片９の天井板下面との当接が解消され、並行クランク機構 34 により左右のタイヤ車輪１が地面に垂直な状態のまま左右の分断横桟 10 ， 11 が中央の縦桟８の上昇につれて回動し左右の縦桟 15 ， 16 が相互に近接して左右の分割荷台ｃ ' ，ｃ ' が略く字状に折り畳まれ、台車ａを縦二つ折りに畳み運搬車の巾方向の長さが縮小するので、この折り畳まれた運搬車をマイカーのトランクの中に格納する。
【００４０】
また、台車ａをアルミニウム合金引抜中空材を適宜切断して形成したので軽量のうえに強靭となり大量生産向けで取り扱いが容易な運搬車となる。
【００４１】
他の構成例を図７，８，９，１０，１１により説明する。
【００４２】
タイヤ車輪１を付設した台車ａの中央の前後方向に架設した縦桟８の前後にチャンネル型の軸受片９を付設し、この前後の軸受片９に夫々中間を分断した台車ａの左分断横桟10と右分断横桟11とを折曲回動自在に軸着し、台車ａの下側の巾方向中央に折曲機構17を設けて折曲自在に形成した折曲保持桟18，19を台車ａの左右端に設けた左縦桟15と右縦桟16との間に架設して台車ａを縦二つ折りに折り畳めるように設ける。
【００４３】
図示した構成例ではこの運搬車の荷台ｄは左右の縦桟15，16間の中央に配設した縦桟８の前後端に下方に開口部を有するチャンネル形状の軸受片９，９を溶接し、この前後の軸受片９，９に夫々左右の分断横桟10，11の基部を軸着ボルト29にて夫々の分断横桟10，11の基部上面が軸受片９の天井板の下面に接するように軸着する。
【００４４】
この前後左右の分断横桟10，11の他端を左右に延設し、この延設端を荷台ｄの左右の端部縦桟32に溶接し、この左右の端部縦桟32の前後にコ字状の枢着片41を溶接にして止着し、この枢着片41に対応する対応枢着片42を夫々左右の縦桟15，16に止着して両者を枢着ピン43で枢着して荷台ｄを平板状の左右に分割された分割荷台ｄ'，ｄ'に構成する。
【００４５】
この荷台ｄの下側の巾方向中央に折曲機構17として連結具44を設け、この連結具44を、図１１のように所定の間隔を置いて右折曲保持桟 19の基部が嵌挿軸着する上下の矩形平板44₁，44₁を対設し、この矩形平板44₁，44₁の相対する後端縁部に縦板44₂を架け渡して溶接にて固定し、矩形平板44₁，44₁の左端縁部に左折曲保持桟18の基部を溶着する係止片44₃を上下の矩形平板44₁，44₁の左端縁部後方寄りに設け、上部の矩形平板44₁に上面が中央の縦桟８の下面に当接する平板状のスペーサ44₄を設けて溶接構成し、この連結具44の上下の矩形平板44₁，44₁に軸着部を設け、この軸着部に断面中空矩形形状のアルミニウム中空引抜材で形成した右折曲保持桟19の基部を嵌挿して軸着ピン45で軸着し、他端を右縦桟16の下面に設けたコ字状枢着部46に止めピン47で突っ張り状態に軸着し、前記係止片44₃に基部を溶着した左折曲保持桟18の延設他端を左縦桟15の下面に設けたコ字状枢着片48に止めピン47にて突っ張り状態に軸着し、この左折曲保持桟18の軸線と右折曲保持桟19の軸線とを図７のように連結具44のほぼ中央でオフセットした状態で配設して両者を上方から見てのやや後方に突出したへ字状に構成する。
【００４６】
本構成例の作用効果について説明する。
【００４７】
常態では左右の分断横桟10，11の基部の上面が軸受片９の天井板の下面に当接し、分断横桟10，11の他端がタイヤ車輪１を介して左右の縦左右15，16に枢着ピン43により軸着保持され、且つ荷台ｄの下側に設けた折曲機構17の左右の折曲保持桟18，19が左右の縦桟15，16を突っ張り状態に張設するので、左右の分割荷台ｄ'，ｄ'は左右の縦桟15，16間に平面平板状態に展開された荷台ｄとして保持される。
【００４８】
また、前記と同様左右のサイドフェンス35の前後に荷止めフェンス38，39を突っ張り状態に掛け渡すことにより荷台ｃを確固に平板状態に展開して保持することができる。
【００４９】
この荷台ｃ上に荷物を載置して運搬する。
【００５０】
運搬車を折り畳むときは、縦桟８を上方に持ち上げると、前記と同様左右の分断横桟10，11の基部上面と軸受片９の天井板下面との当接が解消され、縦桟８の上昇につれて軸着ボルト29を軸芯として左右の縦桟15，16がタイヤ車輪１の接地部が地上で引きづられながら相互に近接して左右の分割荷台ｄ'，ｄ'が略く字状に折り込まれると同時に前記左右の折曲保持桟18，19が上方より見て後方に突設したく字状に折り畳まれる。
【００５１】
この巾方向の長さが縮小された運搬車をマイカーのトランクの中に格納する。
【００５２】
【発明の効果】
本発明を上記のように構成したので、支承筒とハンドルの基部とに弾圧機構により回り止状態に固定する回り止機構を設けたため、この機構により常態では左右のハンドルが前側向きに回り止状態に確固に固定され、このハンドルを引きながら運搬車を移動し、不用時にはハンドルを後側向きで固定して運搬車の長手方向の長さを縮小して格納できるため場所をとらない運搬車となる。
【００５３】
また、使用時には台車の中央の縦桟，左右の縦桟が平板状態で展開されて保持されるので、この台車に荷物を積載し、引きハンドルを引きながら運搬する。
【００５４】
不使用時には、台車ａを縦二つ折りに折り畳み、運搬車の巾方向の長さを縮小したあと、前記と同様ハンドルを後側の向きに回動して固定して運搬車の長手方向の長さを縮小して格納できるので前記と同様場所を取らない運搬車となる。
【００５５】
請求項２の効果は、常態では連結ハンドルにより左右のハンドルを固定具により確固に連結固定できるので、悪路や山道であっても運搬人は左右のハンドルの間に入って腰を入れてハンドルを引動しながら運搬できる。
【００５６】
また、不使用時には連結ハンドルを左右のハンドルから外し、前記弾圧機構と回り止機構により左右の夫々のハンドルを後側の向きに回動して運搬車の長手方向の長さを縮小して格納できる。
