Description
本考案は、特に自動折り畳み傘を展開するときの衝撃力を緩和するための弾性緩衝構造に関するものである。 The present invention relates to an elastic buffer structure for reducing an impact force particularly when an automatic folding umbrella is deployed.
従来の手動折り畳み傘は、手動で展開して使用すると共に、閉じるときは、手動で中棒及び骨構造を折り畳んで傘を収納するものであり、この手動折り畳み傘の操作方法において傘を展開する場合は、使用者が傘の中棒を伸ばして骨構造を展開する操作が必要であり、傘を閉じる場合にも、使用者が中棒を引き戻して骨構造を畳む操作が必要であることから、例えば、使用者が片手で傘を開いたり閉じたりし難いなど、使用上非常に不便であった。 The conventional manual folding umbrella is used by manually unfolding, and when closed, the umbrella is stored by manually folding the middle rod and the bone structure, and the umbrella is deployed in this manual folding umbrella operation method. In this case, the user needs to extend the middle rod of the umbrella to expand the bone structure, and even when closing the umbrella, the user needs to pull the middle rod back and fold the bone structure. For example, it is difficult for the user to open and close the umbrella with one hand.
また、従来の自動折り畳み傘は、中棒の内部に弾性部材が取り付けられているので、使用者が手元にあるボタンを押すと、該弾性部材により中棒を自由に伸縮させて骨構造を連動することにより、傘の展開または収納を簡単に行うことが出来る。また、傘を閉じる時は、中棒にある弾性部材が圧縮している状態であり、その状態で手元のボタンを押すと、中棒にある弾性部材が解放されて自らの付勢力により伸びて骨構造が強力に展開されるため、使用者が手で骨構造を展開する必要はない。 In addition, since the conventional automatic folding umbrella has an elastic member attached to the inside of the middle bar, when the user presses the button at hand, the middle bar can be freely expanded and contracted by the elastic member to interlock the bone structure By doing so, the umbrella can be easily deployed or stored. Also, when closing the umbrella, the elastic member on the center rod is in a compressed state, and when the button on the hand is pressed in that state, the elastic member on the center rod is released and stretched by its own urging force. Since the bone structure is deployed strongly, it is not necessary for the user to manually deploy the bone structure.
しかしながら、既存の自動折り畳み傘は、１つの弾性部材しか有しないことから、中棒の長さに合わせて弾性部材の長さも長くしなければならなく、その弾性部材を解放させると、付勢力が強すぎて、傘を開いた時の衝撃力が大きく、使用者または周りの人にとって非常に危険であるので、改良する必要があった。 However, since the existing automatic folding umbrella has only one elastic member, the length of the elastic member must be increased in accordance with the length of the middle rod, and when the elastic member is released, the urging force is increased. It was too strong and the impact force when opening the umbrella was so great that it was very dangerous for the user or those around him, so it had to be improved.
本考案に係る自動折り畳み傘の弾性緩衝構造は、
それぞれが順に環装する外部管体と中部管体と内部管体からなり、該外部管体は、上下摺動可能に中部管体に環装され、上端にストッパーが取り付けられ、該中部管体は、上下摺動可能に内部管体に環装され、該内部管体の底端に係止ユニットが取り付けられる、中棒と、

In addition, the following Example is only what showed the preferred embodiment of this invention, and the technical scope of this invention is not limited to the following Example itself at all.
図１に示すように、本考案に係る自動折り畳み傘の弾性緩衝構造は、中棒１０と、第一連結座２０と、第二連結座３０と、第一弾性部材４１と、第二弾性部材４２と、第三弾性部材４３を有する。 As shown in FIG. 1, the elastic buffer structure of the automatic folding umbrella according to the present invention includes an intermediate rod 10, a first connecting seat 20, a second connecting seat 30, a first elastic member 41, and a second elastic member. 42 and a third elastic member 43.
前記中棒１０は、外部管体１１と、中部管体１２と、内部管体１３を備え、該外部管体１１は、上下摺動可能に中部管体１２に環装され、該中部管体１２は、上下摺動可能に内部管体１３に環装される。 The middle rod 10 includes an outer tubular body 11, a middle tubular body 12, and an inner tubular body 13. The outer tubular body 11 is mounted on the middle tubular body 12 so as to be slidable up and down. 12 is mounted on the inner tube 13 so as to be slidable up and down.
図１、図２、図４に示すように、前記外部管体１１は、ストッパー１１１及び第一係合部１１２を備え、該ストッパー１１１は、外部管体１１の上端に取り付けられ、その中心に貫通穴が形成され、該第一係合部１１２は、斜めに縮径するように外部管体１１の底端に設けられる。前記中部管体１２は、第二係合部１２１及び第三係合部１２２を備え、該第二係合部１２１は、第一係合部１１２の形状に対応して斜めに拡径するように中部管体１２の上端に設けられ、すなわち、該第一係合部１１２の内径は、第二係合部１２１の外径よりも小さく設定され、該第三係合部１２２は、斜めに縮径するように中部管体１２の底端に設けられる。 As shown in FIGS. 1, 2, and 4, the outer tubular body 11 includes a stopper 111 and a first engaging portion 112, and the stopper 111 is attached to the upper end of the outer tubular body 11, and is at the center thereof. A through hole is formed, and the first engaging portion 112 is provided at the bottom end of the outer tubular body 11 so as to be reduced in diameter obliquely. The middle tubular body 12 includes a second engaging portion 121 and a third engaging portion 122, and the second engaging portion 121 expands obliquely in accordance with the shape of the first engaging portion 112. Provided at the upper end of the middle tube body 12, that is, the inner diameter of the first engagement portion 112 is set smaller than the outer diameter of the second engagement portion 121, and the third engagement portion 122 is inclined. It is provided at the bottom end of the middle tube 12 so as to reduce the diameter.
この構成によれば、前記外部管体１１が中部管体１２の底端から上方に摺動する時に、該外部管体１１が第一係合部１１２を第二係合部１２１に接触させるまで中部管体１２の上端に移動すると、該第一係合部１１２が第二係合部１２１に係止される、つまり、該外部管体１１は中部管体１２に係止されて中部管体１２の上端から脱出することはない。なお、前記外部管体１１の第一係合部１１２の内径は、中部管体１２の第二係合部１２１の外径よりも小さいことから、該外部管体１１が中部管体１２の上端から環装されることができなく、必ず中部管体１２の底端から中部管体１２に環装される。 According to this configuration, when the outer tubular body 11 slides upward from the bottom end of the middle tubular body 12, until the outer tubular body 11 contacts the first engaging portion 112 with the second engaging portion 121. When it moves to the upper end of the middle tube body 12, the first engagement portion 112 is locked to the second engagement portion 121, that is, the outer tube body 11 is locked to the middle tube body 12 and the middle tube body. There is no escape from the top of 12. Since the inner diameter of the first engaging portion 112 of the outer tubular body 11 is smaller than the outer diameter of the second engaging portion 121 of the middle tubular body 12, the outer tubular body 11 is the upper end of the middle tubular body 12. It is not possible to be attached to the middle tube body 12, and the middle tube body 12 is always attached from the bottom end of the middle tube body 12.
前記内部管体１３は、第四係合部１３１を備え、該第四係合部１３１は、第三係合部１２２の形状に対応して斜めに拡径するように内部管体１３の上端に設けられ、すなわち、該第三係合部１２２の内径は、第四係合部１３１の外径よりも小さく設定される。 The inner tube body 13 includes a fourth engagement portion 131, and the fourth engagement portion 131 has an upper end of the inner tube body 13 so as to increase in diameter obliquely corresponding to the shape of the third engagement portion 122. In other words, the inner diameter of the third engagement portion 122 is set smaller than the outer diameter of the fourth engagement portion 131.
この構成によれば、該中部管体１２が内部管体１３の底端から上方に摺動する時に、該中部管体１２が第三係合部１２２を第四係合部１３１に接触させるまで内部管体１３の上端に移動すると、該第三係合部１２２が第四係合部１３１に係止される、つまり、該中部管体１２が内部管体１３に係止されるので、内部管体１３の上端から脱出することはない。なお、前記中部管体１２の第三係合部１２２の内径は、内部管体１３の第四係合部１３１の外径よりも小さいことから、該中部管体１２が内部管体１３の上端から環装されることができなく、必ず内部管体１３の底端から内部管体１３に環装され、さらに、前記内部管体１３の底端に係止ユニット１３２が取り付けられる。 According to this configuration, when the middle tube body 12 slides upward from the bottom end of the inner tube body 13, the middle tube body 12 brings the third engagement portion 122 into contact with the fourth engagement portion 131. When moving to the upper end of the inner tube body 13, the third engagement portion 122 is locked to the fourth engagement portion 131, that is, the middle tube body 12 is locked to the inner tube body 13. There is no escape from the upper end of the tube 13. Since the inner diameter of the third engagement portion 122 of the middle tube body 12 is smaller than the outer diameter of the fourth engagement portion 131 of the inner tube body 13, the middle tube body 12 is the upper end of the inner tube body 13. The inner tube 13 is always mounted from the bottom end of the inner tube 13, and the locking unit 132 is attached to the bottom end of the inner tube 13.

At the same time, the bottom end abuts on the locking unit 132 of the inner tube 13. In the present embodiment, the outer peripheral edge of the third elastic member 43 is in contact with the inner wall of the inner tubular body 13, and the first elastic member 41, the second elastic member 42, and the third elastic member 43 are compression springs. However, the present invention is not limited to this.
本考案は、上述した特徴を備えると共に、既存の自動折り畳み傘の開閉構成を備える。既存の自動折り畳み傘の開閉構成は、紐部材５０を有し、該紐部材５０は、チューブ５１と、紐５２と、係止ヘッド５３を備え、該チューブ５１は、上端を介してストッパー１１１に固定されると共に、該ストッパー１１１の貫通穴を通して外部管体１１の上方から第一連結座２０、第二連結座３０、中部管体１２、内部管体１３に貫設するように、中棒１０の内部に装着される。該紐５２は、チューブ５１を通して下方へ延出するように取り付けられる。該係止ヘッド５３は、紐５２の底端に取り付けられ、内部管体１３の係止ユニット１３２に係止されることができる。 The present invention has the above-described features, and includes an opening / closing configuration of an existing automatic folding umbrella. The open / close configuration of the existing automatic folding umbrella includes a string member 50, which includes a tube 51, a string 52, and a locking head 53. The tube 51 is connected to the stopper 111 via the upper end. The middle rod 10 is fixed so as to penetrate through the first connecting seat 20, the second connecting seat 30, the middle tube 12, and the inner tube 13 from above the outer tube 11 through the through hole of the stopper 111. It is mounted inside. The string 52 is attached so as to extend downward through the tube 51. The locking head 53 is attached to the bottom end of the string 52 and can be locked to the locking unit 132 of the inner tube body 13.
本考案に係る自動折り畳み傘の弾性緩衝構造は、上述した紐部材５０を取り付けて使用することができる。また、使用者が実際の需要により傘を操作すると、操作により、圧縮状態または傘の展開した状態または傘の閉じた状態となることができる。 The elastic buffer structure for an automatic folding umbrella according to the present invention can be used with the above-described string member 50 attached thereto. When the user operates the umbrella according to actual demand, the operation can be in a compressed state, an expanded state of the umbrella, or a closed state of the umbrella.
図１及び図４に示すように、圧縮状態において、外部管体１１と、中部管体１２と、内部管体１３とは、折り畳まれて、最も長く延出した長さの３分の１に縮退し、この縮退状態においては、第一弾性部材４１がストッパー１１１と第一連結座２０との間に折り畳まれ、第二弾性部材４２が第一連結座２０と第二連結座３０との間に折り畳まれ、第三弾性部材４３が第二連結座３０と係止ユニット１３２との間に折り畳まれる。この時、第一連結座２０の下突部２３が第二弾性部材４２に貫設されることから、第二弾性部材４２は、下突部２３と第二連結座３０の内壁との間に挟設され、また、係止ヘッド５３は、内部管体１３の係止ユニット１３２に係合される。 As shown in FIGS. 1 and 4, in the compressed state, the outer tube body 11, the middle tube body 12, and the inner tube body 13 are folded to be one third of the longest extended length. In the retracted state, the first elastic member 41 is folded between the stopper 111 and the first connecting seat 20, and the second elastic member 42 is between the first connecting seat 20 and the second connecting seat 30. The third elastic member 43 is folded between the second coupling seat 30 and the locking unit 132. At this time, since the lower protrusion 23 of the first connection seat 20 penetrates the second elastic member 42, the second elastic member 42 is interposed between the lower protrusion 23 and the inner wall of the second connection seat 30. Further, the locking head 53 is engaged with the locking unit 132 of the inner tube body 13.
図１及び図２に示すように、傘を使用する時は、傘の手元にあるボタン（図示せず）を押し、第一弾性部材４１と第二弾性部材４２と第三弾性部材４３を解放してそれぞれの付勢力により外部管体１１と中部管体１２と内部管体１３を次々伸ばして中棒１０を延長させる。そのうち、該第一弾性部材４１と第二弾性部材４２と第三弾性部材４３はそれぞれ、一方の上端が他方の底端に当接するように取り付けられることから、それぞれ伸ばす時に、それぞれの弾力が互いに相殺されるため、その衝撃力を緩和することができ、それと同時に、係止ヘッド５３は係止ユニット１３２に係合されながら、紐５２を長く伸ばせることから、傘を展開した状態となる。 As shown in FIGS. 1 and 2, when using an umbrella, a button (not shown) on the hand of the umbrella is pushed to release the first elastic member 41, the second elastic member 42, and the third elastic member 43. Then, the outer tube 11, the middle tube 12 and the inner tube 13 are successively extended by the respective urging forces to extend the middle rod 10. Of these, the first elastic member 41, the second elastic member 42, and the third elastic member 43 are each attached such that the upper end of one of them abuts the bottom end of the other. Since the canceling force is offset, the impact force can be reduced. At the same time, the locking head 53 extends the string 52 while being engaged with the locking unit 132, so that the umbrella is unfolded.
図２及び図３に示すように、傘の手元にあるボタンをもう一度押すと、係止ヘッド５３が内部管体１３の係止ユニット１３２から脱出して、紐５２及び係止ヘッド５３がチューブ５１を介して上方へ引っ張られ、傘を閉じる状態となる。つまり、使用者が本考案の弾性緩衝構造の上端を押すと、傘を展開した状態から圧縮状態に復位させて、傘を閉じることができる。 As shown in FIGS. 2 and 3, when the button at the hand of the umbrella is pushed again, the locking head 53 is released from the locking unit 132 of the inner tube 13, and the string 52 and the locking head 53 are moved to the tube 51. It is pulled upwards through and the umbrella is closed. That is, when the user pushes the upper end of the elastic buffer structure of the present invention, the umbrella can be closed from the expanded state to the compressed state.
このように、本考案に係る自動折り畳み傘の弾性緩衝構造は、第一弾性部材４１と第二弾性部材４２と第三弾性部材４３との弾力を互いに相殺することにより、傘の展開時の衝撃力を緩和し、また、その第一弾性部材４１、第二弾性部材４２、第三弾性部材４３はそれぞれ、所定の長さを有することから、圧縮状態から解放した時、それらの弾性部材の伸ばした時の衝撃力を緩和する効果を有するので、手軽に傘を閉じる。故に、本考案に係る自動折り畳み傘の弾性緩衝構造を有すれば、傘をスムーズに開閉できるので、使用上の安全性や利便性を向上させることができる。 As described above, the elastic cushion structure of the automatic folding umbrella according to the present invention cancels the elastic forces of the first elastic member 41, the second elastic member 42, and the third elastic member 43, so Since the first elastic member 41, the second elastic member 42, and the third elastic member 43 have predetermined lengths, the elastic members are stretched when released from the compressed state. Because it has the effect of mitigating the impact force when it hits, close the umbrella easily. Therefore, if it has the elastic buffer structure of the automatic folding umbrella which concerns on this invention, since an umbrella can be opened and closed smoothly, the safety | security and convenience in use can be improved.
