一般の工場、家庭、商店、飛行場などで、多くの物品や旅行かばんの運搬の必 要があり、そのため市場には各式各様の運搬車があり、使用者が重い物品や旅行 かばんを運搬するのに利用され、人力を節約するのに役立っている。ただしこれ ら運搬車の全体のフレームは固定構造とされ、収縮或いは折り畳みができず、ゆ えに物品や旅行かばんを運搬しない時にはその体積が大きいために場所を取り、 収納に不便であった。このような従来の運搬車の欠点を鑑み、ある運搬車ではフ レームを二段折り曲げ式として、車輪と受け台を可動式に展開できるものとして いるが、このような運搬車は実際に使用するときには却って不便なところがあっ た。例えばフレームを折り曲げる時に、使用者がフレームを折り曲げ方を誤ると フレームが滑らかに折り曲げられず、再び元の位置に戻してから再び折り曲げる 必要があり、面倒であったり、また使用者が車輪架と置き台を展開する時には、 まず二つの車輪架を外向きに回転させて後、置き台を展開し、反対に折り畳む時 には上述の二つのステップを経て折り畳む必要があり、面倒であって、このよう に、従来の運搬車は設計及び使用上不便であり、改善が望まれていた。 In general factories, homes, shops, airfields, etc., it is necessary to carry many goods and travel bags.Therefore, there are various types of carriers on the market, and users carry heavy goods and travel bags. It is used to save energy and help save manpower. However, since the entire frame of these vehicles is of a fixed structure, they cannot be contracted or folded, and when they are not used to carry goods or luggage, the volume is so large that they are inconvenient for storage. In view of these drawbacks of conventional transport vehicles, some transport vehicles have a two-fold folding frame that allows the wheels and cradle to be deployed movably, but such transport vehicles are actually used. Sometimes it was rather inconvenient. For example, when bending the frame, if the user misfolds the frame, the frame will not be bent smoothly and it will be necessary to return it to its original position and then bend it again, which is troublesome and When unfolding the stand, first rotate the two wheel racks outward, then unfold the stand, and when folding it in the opposite direction, it is necessary to fold through the above two steps, which is troublesome. As described above, the conventional carrier is inconvenient in design and use, and improvement is desired.

【００１５】 図１、３及び図４に示されるように、平常の押しボタン１２が押されていない 状態の時には、押しボタン１２の挿しピン１２１は、ガイド板１３の斜形孔３４ １の最も内側頂端に停留しており、このとき、内スリーブ管２１に嵌められた固 定座２３の挿しピン部材２３２はばね２３１の外向きの圧迫を受けて上述の外ス リーブ管２２の上挿し孔Ａ内に挿置されている。ゆえに、内スリーブ管２１と外 スリーブ管２２の間は固定状態を呈し、滑動するおそれがない。図５に示される ように、押しボタン１２が下に押されると、挿しピン１２１はガイド板１３の斜 形孔１３Ａの斜面に沿って下に移動し、ガイド板１３を圧迫して内側に移動させ 、ガイド板１３のもう一つの斜形孔１３Ｂもまた上述の連接棒２４を牽引して上 に移動する動作を行う。ゆえに連接棒２４の底端も挿しピン部材２３２上の斜形 ガイド溝２３３上で上に移動する運動を行い、これにより挿しピン部材２３２は 内側に収縮し、並びに外スリーブ管２２の上挿し孔Ａの束縛から離脱する。この とき、内スリーブ管２１は可動状態を呈し、使用者が内スリーブ管２１を外スリ ーブ管２２の内部に向けて圧縮すると、挿しピン部材２３２が外スリーブ管２２ に開設された下挿し孔Ｂ内に挿置され、これにより内スリーブ管２１と外スリー ブ管２２は固定状態を呈し、もって伸縮フレーム２０の収縮が達成される。図２ 及び図６にはすでに収縮した状態が示される。どうように、内スリーブ管２１を 外スリーブ管２２内部より引き伸ばす時には、その操作方式と原理は上述と同じ である。As shown in FIGS. 1, 3 and 4, when the normal push button 12 is not pushed, the insertion pin 121 of the push button 12 is located at the most of the oblique hole 341 of the guide plate 13. The insertion pin member 232 of the fixing seat 23 fitted in the inner sleeve tube 21 is retained at the inner top end, and the insertion pin member 232 of the fixing seat 23 receives the outward compression of the spring 231 and the upper insertion hole of the outer sleeve tube 22 described above. It is inserted in A. Therefore, the inner sleeve pipe 21 and the outer sleeve pipe 22 are in a fixed state and there is no possibility of sliding. As shown in FIG. 5, when the push button 12 is pushed downward, the insertion pin 121 moves downward along the slope of the oblique hole 13A of the guide plate 13, presses the guide plate 13 and moves inward. Then, the other oblique hole 13B of the guide plate 13 also pulls the connecting rod 24 and moves upward. Therefore, the bottom end of the connecting rod 24 is also inserted and moved upward on the oblique guide groove 233 on the pin member 232, whereby the insertion pin member 232 contracts inward and the upper insertion hole of the outer sleeve tube 22. Break away from A's bondage. At this time, the inner sleeve tube 21 is in a movable state, and when the user compresses the inner sleeve tube 21 toward the inside of the outer sleeve tube 22, the insertion pin member 232 is inserted into the outer sleeve tube 22 and is inserted into the lower sleeve. The inner sleeve tube 21 and the outer sleeve tube 22 are fixed in the hole B, whereby the retractable frame 20 is contracted. The already contracted condition is shown in FIGS. When the inner sleeve tube 21 is extended from the inside of the outer sleeve tube 22, the operation method and principle are the same as described above.
