Description

本発明は、ねこ車などの手押し車における荷物を収容する箱の開口を覆う取り扱いが容易な荷台カバーに関する。 The present invention relates to a cargo bed cover that covers an opening of a box that accommodates luggage in a wheelbarrow such as a cat cart and is easy to handle.

特許文献１で開示された荷台カバーは、防水性および可撓性を有するシート本体の周縁部がゴム紐などの伸縮体で縁取りされ、シート本体が荷物を収容する箱の開口を覆うように箱に被せられ、伸縮体におけるシート本体の周縁部より露出した部分が箱の外側のフックに係留されるようになっている。しかしながら、開口の一半部だけをシート本体から開放すると、開口の他半部を覆う側の伸縮性が収縮してフックから外れやすくなる。特許文献２で開示された荷台カバーは、防水性および可撓性を有する合成樹脂からなる袋状に形成されたシート本体には一対の連結具が設けられ、シート本体の周縁部がゴム紐などの伸縮体で縁取りされ、シート本体が荷物を収容する箱の開口を覆うように箱に被せられた後、一対の連結具が箱の下部に回り込んで互いに接続されるようになっている。しかしながら、開口の一半部だけをシート本体から開放すると、開口の他半部を覆う側の伸縮性が収縮し、シート本体が箱の下部の側に移動して開口の他半部から外れやすくなる。つまり、特許文献１および特許文献２で開示された荷台カバーにあっては、開口の一半部を覆い、開口の他半部を開放するように、荷台カバーを使用するという取り扱いが面倒であるという欠点がある。

Specifically, a portion corresponding to the rear edge portion of the sheet body 7 in the rear peripheral bag portion 10 is configured in a cylindrical shape penetrating in the left-right direction. The portions corresponding to the left and right edge portions of the sheet body 7 in the rear peripheral bag portion 10 are configured in a cylindrical shape penetrating in the front-rear direction. The curtain piece 11 is provided at the left and right edge portions of the sheet body 7 as a pair that protrudes outward in the left-right direction from the portion corresponding to the central bag portion 8 in the sheet body 7. The central bag portion 8, the front peripheral bag portion 9, the rear peripheral bag portion 10, and the curtain piece 11 are made of a synthetic resin or cloth having the same material as the seat body 7 and having waterproofness and flexibility.

前伸縮体１２および後伸縮体１３は、ゴムチューブまたはゴム紐などの紐状に構成され、前周辺袋部９および後周辺袋部１０に個別に対応する。前伸縮体１２は、中央袋部８の内部および前周辺袋部９の内部を順に経由しかつ箱２の開口の前半部よりも小さな１個の環状として構成され、箱２の開口の前半部よりも大きな環状となるように中央袋部８および前周辺袋部９を順に経由する方向に伸縮可能である。後伸縮体１３は、中央袋部８の内部および後周辺袋部１０の内部を順に経由しかつ箱２の開口の後半部よりも小さな１個の環状体として構成され、箱２の開口の後半部よりも大きな環状となるように中央袋部８および後周辺袋部１０を順に経由する方向に伸縮可能である。 The front elastic body 12 and the rear elastic body 13 are formed in a string shape such as a rubber tube or a rubber string, and individually correspond to the front peripheral bag portion 9 and the rear peripheral bag portion 10. The front elastic body 12 passes through the inside of the central bag portion 8 and the inside of the front peripheral bag portion 9 in order, and is configured as one ring that is smaller than the front half portion of the opening of the box 2, and the front half portion of the opening of the box 2 It can be expanded and contracted in a direction passing through the central bag portion 8 and the front peripheral bag portion 9 in order so as to have a larger ring shape. The rear elastic body 13 is configured as one annular body that sequentially passes through the inside of the central bag portion 8 and the inside of the rear peripheral bag portion 10 and is smaller than the rear half portion of the opening of the box 2. It can be expanded and contracted in a direction passing through the central bag portion 8 and the rear peripheral bag portion 10 in order so as to form an annular shape larger than the portion.

保持具１４は、中央袋部８の内部を貫通し、中央袋部８から左右方向に突出する、ゴムチューブまたはゴム紐などの１本の紐として構成され、左右方向に伸縮可能である。中央袋部８から外側に突出した保持具１４の一端部には、連結具１５が接続される。中央袋部８から外側に突出した保持具１４の他端部には、被連結具１６が接続される。そして、被連結具１６が連結具１５の挿入孔１７から内部に挿入されることによって、連結具１５に内蔵された図外の鉤部が連結具１５に抜けないようにロックされ、連結具１５と被連結具１６とが互いに連結される。その状態において、作業者が連結具１５の釦１８を押すと、上記鉤部による連結具１５に対するロックが解除され、被連結具１６が連結具１５から取り外される。連結具１５および被連結具１６が中央袋部８の内部に挿入不可能な大きさであれば、保持具１４が中央袋部８から抜けないという利点がある。 The holder 14 is configured as a single string such as a rubber tube or a rubber string that penetrates the inside of the central bag part 8 and protrudes from the central bag part 8 in the left-right direction, and is extendable in the left-right direction. A connector 15 is connected to one end of the holder 14 that protrudes outward from the central bag portion 8. A to-be-connected tool 16 is connected to the other end portion of the holding tool 14 protruding outward from the central bag part 8. And the to-be-connected tool 16 is inserted into the inside of the insertion hole 17 of the connecting tool 15, so that a hook part (not shown) built in the connecting tool 15 is locked so as not to come out of the connecting tool 15. Are connected to each other. In this state, when the operator presses the button 18 of the connector 15, the lock on the connector 15 by the collar is released, and the connector 16 is removed from the connector 15. If the connecting tool 15 and the connected tool 16 are of a size that cannot be inserted into the central bag portion 8, there is an advantage that the holding tool 14 cannot be removed from the central bag portion 8.

図１を参照し、荷台カバー６が手押し車１の箱２に装着される場合について説明する。前伸縮体１２が伸ばされ、前周辺袋部９が箱２の開口における前半部を囲む前壁の外側面および左右側壁の外側面を囲み、前伸縮体１２がビード５を上方から下方に越えて収縮して前周辺袋部９を箱２の開口における前半部を囲む前壁の外側面および左右側壁の外側面に接触させる一方、後伸縮体１３が伸ばされ、後周辺袋部１０が箱２の開口における後半部を囲む後壁の外側面および左右側壁の外側面を囲み、後伸縮体１３がビード５を上方から下方に越えて収縮して後周辺袋部１０を箱２の開口における後半部を囲む後壁の外側面および左右側壁の外側面に接触させることによって、シート本体７が箱２の開口を全体的に覆う。 With reference to FIG. 1, the case where the loading platform cover 6 is mounted on the box 2 of the handcart 1 will be described. The front elastic body 12 is stretched, the front peripheral bag portion 9 surrounds the outer surface of the front wall and the outer surfaces of the left and right side walls surrounding the front half of the opening of the box 2, and the front elastic body 12 crosses the bead 5 from above to below. The front peripheral bag portion 9 is brought into contact with the outer surface of the front wall and the outer surfaces of the left and right side walls surrounding the front half of the opening of the box 2 while the rear elastic body 13 is extended, and the rear peripheral bag portion 10 is 2 surrounds the outer side surface of the rear wall and the outer side surfaces of the left and right side walls surrounding the rear half of the opening, and the rear elastic body 13 contracts from the upper side to the lower side of the bead 5 so that the rear peripheral bag part 10 is The sheet main body 7 entirely covers the opening of the box 2 by making contact with the outer surface of the rear wall surrounding the rear half and the outer surfaces of the left and right side walls.

また、中央袋部８から外側に突出した保持具１４の一端部が箱２の右側壁の外側に配置され、中央袋部８から外側に突出した保持具１４の他端部が箱２の左側壁の外側から箱２の底部の外側を経由して箱２の右側壁の外側に回り込まされ、保持具１４が左右方向に復元するための弾力を蓄えつつ伸張し、連結具１５と被連結具１６とが互いに連結される。これによって、左右方向に伸縮可能な素材で構成された保持具１４がシート本体７と中央袋部８と幕片１１および箱２の前後方向の中央部を一周して上記蓄えられた復元するための弾力の一部で左右方向に収縮してシート本体７と中央袋部８および幕片１１を箱２に保持するので、荷台カバー６が図３に示すように手押し車１の箱２に好適に装着されるという利点がある。 Also, one end of the holder 14 protruding outward from the central bag portion 8 is disposed outside the right side wall of the box 2, and the other end of the holder 14 protruding outward from the central bag portion 8 is the left side of the box 2. From the outside of the wall to the outside of the right side wall of the box 2 via the outside of the bottom of the box 2, the holder 14 expands while accumulating elasticity for restoring in the left-right direction, and the connecting tool 15 and the connected tool 16 are connected to each other. As a result, the holder 14 made of a material that can be expanded and contracted in the left-right direction goes around the sheet body 7, the central bag portion 8, the curtain piece 11, and the central portion in the front-rear direction of the box 2 to restore the stored data. The seat body 7, the central bag portion 8 and the curtain piece 11 are held in the box 2 by being contracted in the left-right direction by a part of the elasticity of the load, so that the cargo bed cover 6 is suitable for the box 2 of the handcart 1 as shown in FIG. There is an advantage of being attached to.

図３を参照し、手押し車１の箱２に装着された荷台カバー６の取り扱い方について説明する。前伸縮体１２および後伸縮体１３が互いに独立した伸縮可能な環状に構成され、保持具１４がシート本体７および中央袋部８を箱２に保持するので、箱２の開口の一半部を覆い、箱２の開口の他半部を開放するように、シート本体７を使用するという取り扱いが容易であるという利点がある。 With reference to FIG. 3, how to handle the carrier cover 6 mounted on the box 2 of the handcart 1 will be described. The front stretchable body 12 and the rear stretchable body 13 are configured to be mutually stretchable and annular, and the holder 14 holds the sheet body 7 and the central bag portion 8 in the box 2, so that one half of the opening of the box 2 is covered. There is an advantage that it is easy to handle by using the sheet body 7 so as to open the other half of the opening of the box 2.

その理由は、例えば、箱２の開口の一半部としての前半部を覆い、箱２の開口の他半部としての後半部を開放する場合、作業者が後周辺袋部１０を手で上方に持ち上げて箱２から剥がすことによって、後伸縮体１３が中央袋部８の側に収縮しつつ後周辺袋部１０およびシート本体７の中央袋部８よりも後方における部分を中央袋部８の側に集合させ、箱２の開口の後半部が開放されるが、シート本体７の中央袋部８よりも前方における部分は前伸縮体１２および保持具１４によって箱２の開口の前半部を覆ったままになるからである。 The reason is that, for example, when the front half as one half of the opening of the box 2 is covered and the latter half as the other half of the opening of the box 2 is opened, the operator moves the rear peripheral bag portion 10 upward by hand. By lifting and peeling from the box 2, the rear elastic body 13 is contracted to the central bag portion 8 side while the rear peripheral bag portion 10 and the portion behind the central bag portion 8 of the sheet body 7 are placed on the central bag portion 8 side. The second half of the opening of the box 2 is opened, but the front part of the seat body 7 in front of the central bag part 8 covers the front half of the opening of the box 2 with the front stretchable body 12 and the holder 14. Because it will remain.

また、箱２の開口の一半部としての後半部を覆い、箱２の開口の他半部としての前半部を開放する場合、作業者が前周辺袋部９を手で上方に持ち上げて箱２から剥がすことによって、前伸縮体１２が中央袋部８の側に収縮しつつ前周辺袋部９およびシート本体７の中央袋部８よりも前方における部分を中央袋部８の側に集合させ、箱２の開口の前半部が開放されるが、シート本体７の中央袋部８よりも後方における部分は後伸縮体１３および保持具１４によって箱２の開口の後半部を覆ったままになるからである。 Further, when the latter half of the opening of the box 2 is covered and the front half of the opening of the box 2 is opened, the operator lifts the front peripheral bag portion 9 upward by hand to raise the box 2. The front stretchable body 12 is contracted to the side of the central bag part 8 by peeling off from the front peripheral bag part 9 and the part in front of the central bag part 8 of the seat body 7 is gathered on the side of the central bag part 8, The front half of the opening of the box 2 is opened, but the rear part of the seat body 7 behind the central bag part 8 remains covered with the rear elastic body 13 and the holder 14 in the latter half of the opening of the box 2. It is.

図４を参照し、前伸縮体１２、後伸縮体１３、保持具１４が中央袋部８に配置された構造について説明する。中央袋部８には、３つの部屋１９；２０；２１が２つの接合部２２；２３によって前後方向に分かれて設けられる。これらの部屋１９；２０；２１は、図３の紙面の表裏の方向である左右方向に個別に貫通する筒状に構成される。前方の部屋１９には、前伸縮体１２における中央袋部８に対応する部分が配置される。後方の部屋２１には、後伸縮体１３における中央袋部８に対応する部分が配置される。中央の部屋２０には、保持具１４が配置される。このように前伸縮体１２と後伸縮体１３および保持具１４が中央袋部８に後方向に分かれた３つの部屋１９；２０；２１に別々に配置されることによって、前伸縮体１２と後伸縮体１３および保持具１４が互いに絡まり合うことはなく、荷台カバー６の取り扱いが容易であるという利点がある。 With reference to FIG. 4, the structure where the front elastic body 12, the rear elastic body 13, and the holder 14 are arrange | positioned at the center bag part 8 is demonstrated. The central bag portion 8 is provided with three chambers 19; 20; 21 separated by two joint portions 22; 23 in the front-rear direction. These rooms 19; 20; 21 are configured in a cylindrical shape penetrating individually in the left-right direction, which is the front and back direction of the paper surface of FIG. In the front room 19, a portion corresponding to the central bag portion 8 in the front elastic body 12 is arranged. In the rear chamber 21, a portion corresponding to the central bag portion 8 in the rear elastic body 13 is arranged. A holder 14 is disposed in the central room 20. Thus, the front elastic body 12 and the rear elastic body 13 and the holder 14 are separately disposed in the three chambers 19; The stretchable body 13 and the holder 14 are not entangled with each other, and there is an advantage that handling of the cargo bed cover 6 is easy.

図５を参照し、シート本体７が箱２の開口を覆った構造について説明する。前伸縮体１２または後伸縮体１３がビード５よりも下方に配置されて前周辺袋部９または後周辺袋部１０を箱２の外側面に押えているので、箱２の開口を覆うシート本体７の姿勢が安定するという利点がある。 A structure in which the sheet body 7 covers the opening of the box 2 will be described with reference to FIG. Since the front elastic body 12 or the rear elastic body 13 is disposed below the bead 5 and presses the front peripheral bag portion 9 or the rear peripheral bag portion 10 against the outer surface of the box 2, the sheet body covering the opening of the box 2 There is an advantage that the posture of 7 is stabilized.

図６を参照し、幕片１１の作用について説明する。幕片１１が連結具１５で箱２のビード５を上下方向に囲むように箱２に押し付けられるので、水などが図３に示す前周辺袋部９と後周辺袋部１０との間の隙間から箱２の内部に侵入しないという利点がある。 The operation of the curtain piece 11 will be described with reference to FIG. Since the curtain piece 11 is pressed against the box 2 so as to surround the bead 5 of the box 2 with the connecting tool 15 in the vertical direction, water or the like is a gap between the front peripheral bag part 9 and the rear peripheral bag part 10 shown in FIG.
