Description

本発明は、軸方向レバー操作型ロック装置を具備する杖に関し、より詳細には、ロックレバーを杖の長さ方向に配置し、連結管の径方向左右両側から締付力を加えるようにすることにより、操作力は少なくかかり、ロック力は増大し、かつロック力の微調整も可能にする軸方向レバー操作型ロック装置を具備する杖に関する。   The present invention relates to a cane equipped with an axial lever operation type locking device, and more specifically, the lock lever is arranged in the length direction of the cane, and a tightening force is applied from both the left and right sides of the connecting pipe in the radial direction. Thus, the present invention relates to a cane equipped with an axial lever operation type locking device that requires less operating force, increases locking force, and enables fine adjustment of the locking force.

一般に、杖は、登山、スポーツ競技又は患者の歩行補助用等のように、使用者の身体を支える補助手段として使用される。こうした杖は、ポールの端部にハンドルを具備した形態からなる。ポールは、通常、複数の連結管を互いに挿入、結合して、保管時や使用時にいわゆる“テレスコピック方式”や“アンテナ方式”により長さ方向に伸縮することができるようになっている。   Generally, a cane is used as an auxiliary means for supporting a user's body, such as for mountain climbing, sports competitions, or for assisting walking of a patient. Such a cane has a configuration in which a handle is provided at an end of a pole. The pole is usually configured such that a plurality of connecting pipes are inserted and joined to each other, and can be expanded and contracted in the length direction by so-called “telescopic method” or “antenna method” during storage or use.

杖のロック装置は、連結管を伸長させた状態や短縮させた状態で隣り合う2つの連結管をロックするようにする機構であり、図1〜図3には、女性や高齢者も苦労せず操作することができるようにした従来のレバー式ロック装置が図示されている。   The locking device for the cane is a mechanism that locks two adjacent connecting pipes in a state where the connecting pipe is extended or shortened. FIGS. A conventional lever-type locking device is shown which can be operated without delay.

図1〜図3に示されたところのように、従来のレバー式ロック装置10は、径の大きい上部連結管2の端部に設置され、カムレバー40の操作により把持環20を窄めて径の小さい下部連結管4を締めて固定するようになっている。   As shown in FIGS. 1 to 3, the conventional lever type locking device 10 is installed at the end of the upper connecting pipe 2 having a large diameter, and the grip ring 20 is narrowed by operating the cam lever 40. The lower connecting pipe 4 having a small diameter is fastened and fixed.

ロック装置10の把持環20は、円周方向の一方のみが切開部22により上下に分けられ、切開部22の上下部に延長板24が形成されており、上下の延長板24には作動ピン30が貫通し、作動ピン30にはカムレバー40がヒンジピン50により連結され、カムレバー40にはカム面42が形成された形態からなっている。   The grip ring 20 of the locking device 10 is divided into upper and lower portions only by one in the circumferential direction by an incision portion 22, and extension plates 24 are formed on the upper and lower portions of the incision portion 22. The cam lever 40 is connected to the operating pin 30 by a hinge pin 50, and the cam surface 40 is formed on the cam lever 40.

このようなロック装置10について図3を参照しつつ説明すると、カムレバー40を把持環20側に押すことにより、カム面42が回転しながら作動ピン30を引くことになり、作動ピン30により上・下部延長板24が引かれながら把持環20を締めるようになり、下部連結管4を加圧して固定するようになる。   Such a locking device 10 will be described with reference to FIG. 3. When the cam lever 40 is pushed toward the grip ring 20, the operating pin 30 is pulled while the cam surface 42 rotates. The grip ring 20 is tightened while the lower extension plate 24 is pulled, and the lower connecting pipe 4 is pressurized and fixed.

ところで、従来のロック装置10は、カムレバー40が連結管2,4の径方向に回動するようになっており、カムレバー40の形状は、連結管2,4の円弧形状に沿って曲がった形態からならざるを得ない。   By the way, the conventional locking device 10 is configured such that the cam lever 40 rotates in the radial direction of the connecting pipes 2 and 4, and the shape of the cam lever 40 is bent along the arc shape of the connecting pipes 2 and 4. I must come from.

そのため、カムレバー40の長さ全体を延長するには限界があり、十分なロック力を発揮できず、ロック時には大きな力を必要とするようになるため、高齢者や女性が操作することが容易ではない。特に、図2から分かるように、カムレバー40の端点とヒンジピン50の位置関係、及びカムレバー40が円弧形状である点に起因して、カムレバー40の端部を押してもロックする力がまったく伝達されない。したがって、カムレバー40をロックするために押すべき部分がカムレバー40の中間地点に形成されるため、梃として作用する長さが非常に短くなり、レバー型ロック装置の長所である梃の効果を十分に発揮することができない。   For this reason, there is a limit to extending the entire length of the cam lever 40, and a sufficient locking force cannot be exerted, and a large force is required at the time of locking. Absent. In particular, as can be seen from FIG. 2, due to the positional relationship between the end point of the cam lever 40 and the hinge pin 50 and the point that the cam lever 40 has an arc shape, no locking force is transmitted even if the end of the cam lever 40 is pushed. Therefore, since the portion to be pushed to lock the cam lever 40 is formed at the intermediate point of the cam lever 40, the length acting as a heel becomes very short, and the effect of the heel which is an advantage of the lever type locking device is sufficiently obtained. I can't demonstrate it.

また、把持環20の一方のみが切開され、切開された側でのみ把持環20を締める形態であるため、下部連結管4を加圧する力が円周全体にわたって均一に作用することができない。また、把持環20の円弧の長さがあまりに長いため、下部連結管4を加圧する際に把持環20が伸びやすい。したがって、把持環20を強く締めることができず、ロック力を十分に与えることができず、繰返しの使用によりロック力が急激に低下する。
また、図3から分かるように、カムレバー40をロックしたときに、カム面42と延長板24との接触地点が把持環20の中心から半径方向に遠く離れているので、上下部延長板24を引く力が把持環20に伝達される前に過度に失われる。
In addition, since only one of the gripping rings 20 is incised, and the gripping ring 20 is tightened only on the incised side, the force for pressurizing the lower connecting pipe 4 cannot act uniformly over the entire circumference. Moreover, since the length of the circular arc of the holding ring 20 is too long, the holding ring 20 is easily extended when the lower connecting pipe 4 is pressurized. Therefore, the grip ring 20 cannot be tightened strongly, and the lock force cannot be sufficiently applied, and the lock force is rapidly reduced by repeated use.
As can be seen from FIG. 3, when the cam lever 40 is locked, the contact point between the cam surface 42 and the extension plate 24 is far away from the center of the grip ring 20 in the radial direction. The pulling force is lost excessively before being transmitted to the grip ring 20.

本発明は、前記した従来の問題を解決するためのものであり、本発明の目的は、大きな操作力を必要とせず、ロック力を大幅に増大させることができ、繰返し使用にも長期間耐久性を維持することができるようにする軸方向レバー操作型ロック装置を具備する杖を提供することにある。   The present invention is intended to solve the above-described conventional problems, and the object of the present invention is that a large operating force is not required, the locking force can be greatly increased, and durability for repeated use for a long time is also provided. It is an object of the present invention to provide a cane having an axial lever operation type lock device that can maintain the performance.

本発明の他の目的は、ロック力の微調整も可能にすることにある。   Another object of the present invention is to enable fine adjustment of the locking force.

上述した目的を達成するために、複数の連結管が長さ方向に伸縮自在に結合され、複数の連結管のうち径の大きい上部連結管に軸方向に伸縮自在に挿入された径の小さい下部連結管をロック又は解除可能な杖であって、半径方向左右両側が切開部として切開されて上部と下部にそれぞれ上部弧形把持片と下部弧形把持片が独立して形成され、上部弧形把持片及び下部弧形把持片それぞれの左右両側に押圧部が外延されて、前記上部連結管の端部に固定される把持用チューブ;前記上部弧形把持片及び下部弧形把持片の対向する左右両側の押圧部にそれぞれ上下方向に貫通する形態で組み立てられる作動ピン;及び、杖の長さ方向に延長される形態の押圧板と、押圧板の端部に形成されて前記左右作動ピンの上部突出端部に杖の長さ方向に回動される状態でヒンジ結合されるカム型ヒンジ部を有する軸方向レバーを含むことを特徴とする。   In order to achieve the above-described object, a plurality of connecting pipes are stretchably coupled in the length direction, and the lower diameter part is inserted into the upper connecting pipe having a larger diameter among the plurality of connecting pipes so as to be stretchable in the axial direction. A cane that can lock or release the connecting tube, and the left and right sides in the radial direction are incised as incisions, and an upper arc-shaped gripping piece and a lower arc-shaped gripping piece are formed independently on the upper and lower parts, respectively, Gripping tubes with pressing portions extending outwardly on the left and right sides of each of the gripping piece and the lower arc-shaped gripping piece and fixed to the end of the upper connecting pipe; the upper arc-shaped gripping piece and the lower arc-shaped gripping piece face each other Actuating pins assembled in the form of vertically penetrating the pressing parts on both the left and right sides; a pressing plate extending in the length direction of the cane; and the left and right operating pins formed on the end of the pressing plate Rotates in the length direction of the cane at the upper protruding end Characterized in that it comprises an axial lever having a cam hinge portion hingedly coupled condition.

本発明の他の方向による軸方向レバー操作型ロック装置を具備する杖は、複数の連結管が長さ方向に伸縮自在に結合され、複数の連結管のうち径の大きい上部連結管に軸方向に伸縮自在に挿入された径の小さい下部連結管をロック又は解除可能な杖であって、上部連結管の端部に結合される胴部と、胴部から延長され、半径方向左右両側が切開部として切開されて上部と下部にそれぞれ独立して形成される上部弧形把持片及び下部弧形把持片と、上部弧形把持片及び下部弧形把持片それぞれの左右両側に外延される押圧部を含み、前記左右両側の押圧部を上下に貫通する貫通孔が形成されている把持用チューブ;前記両側の押圧部の貫通孔にそれぞれ上下方向に挿入される作動ピン;及び、杖の長さ方向に延長される形態の押圧板と、押圧板から延長されて前記両側の作動ピンの上部突出端部に杖の長さ方向に回動されるようにヒンジ結合されるカム型ヒンジ部を有する軸方向レバーを含むことを特徴とする。   A cane having an axial lever operation type locking device according to another direction of the present invention includes a plurality of connecting pipes that are elastically coupled in the length direction, and an axial direction of an upper connecting pipe having a large diameter among the plurality of connecting pipes. A cane that can lock or release a lower connecting pipe with a small diameter that is inserted in a telescopic manner, and a trunk that is coupled to an end of the upper connecting pipe, and is extended from the torso, and both the left and right sides in the radial direction are incised. The upper arc-shaped gripping piece and the lower arc-shaped gripping piece that are incised as parts and formed independently at the upper and lower parts, and the pressing parts that are extended to the left and right sides of the upper arc-shaped gripping piece and the lower arc-shaped gripping piece, respectively. A gripping tube in which a through-hole penetrating up and down the left and right pressing parts is formed; an operating pin inserted vertically into each of the through-holes of the pressing parts on both sides; and the length of the cane A pressing plate extending in the direction, and the pressing plate It is al extension, characterized in that it comprises an axial lever having a cam hinge portion hingedly coupled to be rotated in the longitudinal direction of the cane to the upper projecting end portion of the opposite sides of the actuating pin.

作動ピンは、前記把持用チューブの押圧部の貫通孔に上下方向に滑動自在に挿入され、上端部に軸方向レバーがヒンジ結合する上部ピンと、前記押圧部の貫通孔に下方から上方へ挿入されて前記上部ピンとねじ結合され、頭部が下部押圧部に掛かる調節ネジからなることが好ましい。   The operating pin is inserted into the through hole of the pressing portion of the gripping tube so as to be slidable in the vertical direction. The upper pin is hinged to the upper end of the axial lever, and the operating pin is inserted into the through hole of the pressing portion from below upward. It is preferable that the adjusting pin is screwed to the upper pin and the head is engaged with the lower pressing portion.

前記把持用チューブの上下押圧部間の切開部には、前記調節ネジの外周を保持して緩みを防止するための緩み防止具を固定して設置することが好ましい。   It is preferable that a loosening prevention tool for holding the outer periphery of the adjusting screw and preventing loosening is fixed and installed at the incision portion between the upper and lower pressing portions of the gripping tube.

ここで、緩み防止具は、下部押圧部の上面に固定されるベースと、前記ベースの中間に形成されて前記調節ネジの外周面を弾性加圧する複数の弾性片を含む。   Here, the loosening prevention tool includes a base fixed to the upper surface of the lower pressing portion and a plurality of elastic pieces that are formed in the middle of the base and elastically pressurize the outer peripheral surface of the adjusting screw.

前記把持用チューブの上下部弧形把持片と胴部との間の左右側には、切欠溝が形成される。   Cutout grooves are formed on the left and right sides between the upper and lower arc-shaped gripping pieces and the body portion of the gripping tube.

本発明に係る軸方向レバー操作型ロック装置を具備する杖によれば、軸方向レバーが杖の長さ方向に配置された構造であり、梃の作用をする軸方向レバーの長さを必要な長さに延長して、少ない力で高いロック力を得ることができる。また、軸方向レバーの延長形態も、力の作用方向に屈曲せず、軸方向レバーに作用した力が把持用チューブに損失なく完全に伝達される。   According to the cane having the axial lever operation type locking device according to the present invention, the axial lever is arranged in the length direction of the cane, and the length of the axial lever that acts as a hook is required. By extending the length, a high locking force can be obtained with a small force. In addition, the extension form of the axial lever is not bent in the direction in which the force is applied, and the force acting on the axial lever is completely transmitted to the gripping tube without any loss.

また、把持用チューブが上部弧形把持片と下部弧形把持片により上下部に2つの要素に分割される一方、軸方向レバーのカムが連結管の径方向左右両側において作動ピンを引いて上下の弧形把持片を締める形態からなっていてロック力が一層増大し、増大したロック力は連結管の外周面全体にバランスよく均一に作用する。   The gripping tube is divided into two elements at the top and bottom by the upper arc-shaped gripping piece and the lower arc-shaped gripping piece, while the cam of the axial lever pulls the operating pin on both the left and right sides in the radial direction of the connecting pipe. The locking force is further increased, and the increased locking force acts uniformly on the entire outer peripheral surface of the connecting pipe in a balanced manner.

また、連結管に接する上部弧形把持片と下部弧形把持片それぞれの円弧の長さが従来の半分程度に短くなるため、ロック力を大きく加えても簡単に伸びず、それによりロック力を十分に増大させることができ、耐久性も大幅に向上する。   In addition, the arc length of the upper arc-shaped gripping piece and the lower arc-shaped gripping piece that are in contact with the connecting pipe is reduced to about half of the conventional arc length. It can be increased sufficiently and the durability is greatly improved.

また、作動ピンと押圧部が連結管の径方向両側に配置される一方、カム面が杖の長さ方向に回動する構造であるため、力の作用点が従来に比べて連結管の中心軸により近く位置するようになってロック力をさらに増大させることができ、ロック力が増大しても押圧部が変形するおそれがない。   In addition, since the operating pin and the pressing part are arranged on both sides in the radial direction of the connecting pipe, the cam surface rotates in the length direction of the cane, so that the point of action of the force is the central axis of the connecting pipe compared to the conventional case As a result, the locking force can be further increased and the pressing portion can be prevented from being deformed even if the locking force is increased.

また、上部ピンと調節ネジのネジ結合により作動ピンの長さを増減させることができるため、必要に応じてロック力を調節できる利便性がある。   Further, since the length of the operating pin can be increased or decreased by screw connection of the upper pin and the adjusting screw, there is a convenience that the locking force can be adjusted as necessary.

以下、添付図面を参照しつつ、本発明の好適な実施例について具体的に説明する。   Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

図4〜図6に示したところのように、本発明の杖は、径の大きい上部連結管2の端部にロック装置100を設置し、ロック装置100の軸方向レバー400を回動させて径の小さい下部連結管4を固定又は解除するようになっている。   As shown in FIGS. 4 to 6, in the cane of the present invention, the locking device 100 is installed at the end of the upper connecting pipe 2 having a large diameter, and the axial lever 400 of the locking device 100 is rotated. The lower connecting pipe 4 having a small diameter is fixed or released.

ロック装置100は、半径方向左右両側が切開部222として切開されて上部と下部にそれぞれ上部弧形把持片220と下部弧形把持片230が独立して形成される把持用チューブ200と、上部弧形把持片220と下部弧形把持片230の両側を上下方向に貫通して設置される作動ピン300,300と、作動ピン300,300に結合されて杖の長さ方向に回動する軸方向レバー400を含む。   The locking device 100 includes a grasping tube 200 in which the left and right sides in the radial direction are incised as incisions 222, and an upper arc-shaped gripping piece 220 and a lower arc-shaped gripping piece 230 are independently formed on the upper and lower parts, respectively, Actuating pins 300, 300 installed vertically through both sides of the shaped gripping piece 220 and the lower arc-shaped grasping piece 230, and an axial direction coupled to the working pins 300, 300 and rotating in the length direction of the cane A lever 400 is included.

把持用チューブ200の上部弧形把持片220と下部弧形把持片230は、胴部210から延長され、胴部210は、上部連結管2に結合されて固定される。胴部210と弧形把持片220,230との間の左右両側には、切欠溝212が形成され、それにより弧形把持片220,230がより良好に伸縮することができる。   The upper arc-shaped gripping piece 220 and the lower arc-shaped gripping piece 230 of the gripping tube 200 are extended from the body portion 210, and the body portion 210 is coupled and fixed to the upper connecting pipe 2. Notch grooves 212 are formed on both the left and right sides between the body 210 and the arc-shaped gripping pieces 220 and 230, so that the arc-shaped gripping pieces 220 and 230 can expand and contract better.

把持用チューブ200の上部弧形把持片220及び下部弧形把持片230の左右両側にはそれぞれ押圧部224,234が外延され、押圧部224,234には貫通孔226,236が上下方向に形成される。   Pressing portions 224 and 234 are extended to the left and right sides of the upper arc-shaped gripping piece 220 and the lower arc-shaped gripping piece 230 of the gripping tube 200, and through holes 226 and 236 are formed in the pressing portions 224 and 234 in the vertical direction. Is done.

作動ピン300は、押圧部224,234の貫通孔226,236に下方から上方へ挿入され、上端部が上部押圧部224の上側に突出される。作動ピン300の突出端部にはカム形態の軸方向レバー400がヒンジ結合される。作動ピン300は、軸方向レバー400のカム方式の回動と組み合わせて、上下方向に移動することにより、上下押圧部224,234を締めたり解いたりする。   The operating pin 300 is inserted into the through holes 226 and 236 of the pressing portions 224 and 234 from the lower side to the upper side, and the upper end portion protrudes above the upper pressing portion 224. A cam-shaped axial lever 400 is hinged to the protruding end of the operating pin 300. The operating pin 300 moves in the vertical direction in combination with the cam-type rotation of the axial lever 400, thereby tightening or unfastening the vertical pressing portions 224, 234.

作動ピン300は、長さの変化を可能にしてロック力を調節することができる形態で構成することが好ましい。このため、作動ピン300は、上部ピン310と調節ネジ320に分割されて、互いにネジ結合された形態で構成していてもよい。上部ピン310及び調節ネジ320は、ネジ部314(図6参照)と、ネジ部322によって結合される。ネジ部314,322の調節により作動ピン300の全体長さを変化させると、押圧部224,234の締付量、すなわち締付力が増減される。調節ネジ320の頭部324は、下部押圧部234に密着する。調節ネジ320の頭部324と押圧部234との間にはワッシャ330を介在していてもよい。   The operating pin 300 is preferably configured in such a manner that the lock force can be adjusted by changing the length. Therefore, the operating pin 300 may be divided into an upper pin 310 and an adjusting screw 320 and may be configured to be screwed together. The upper pin 310 and the adjustment screw 320 are coupled to the screw portion 314 (see FIG. 6) and the screw portion 322. When the entire length of the operating pin 300 is changed by adjusting the screw portions 314 and 322, the tightening amount of the pressing portions 224 and 234, that is, the tightening force is increased or decreased. The head 324 of the adjustment screw 320 is in close contact with the lower pressing portion 234. A washer 330 may be interposed between the head 324 of the adjustment screw 320 and the pressing portion 234.

作動ピン300の上部突出端部、すなわち上部ピン310の突出端部には、軸方向レバー400のヒンジ結合のためのヒンジ孔312が形成される。   A hinge hole 312 for hinge coupling of the axial lever 400 is formed at the upper protruding end of the operating pin 300, that is, the protruding end of the upper pin 310.

軸方向レバー400は、押圧板410が杖の長さ方向に延長される形態からなる。押圧板410は、上部連結管2の外周面に適切に覆われるように横断面が弧形からなる。押圧板410の端部にはカム型ヒンジ部420が形成され、カム型ヒンジ部420には、結合孔424が形成され、結合孔424の周辺にカム面422が凸状に形成される。   The axial lever 400 has a configuration in which the pressing plate 410 is extended in the length direction of the cane. The pressing plate 410 has an arc shape in cross section so as to be properly covered with the outer peripheral surface of the upper connecting pipe 2. A cam-type hinge part 420 is formed at the end of the pressing plate 410, a coupling hole 424 is formed in the cam-type hinge part 420, and a cam surface 422 is formed in a convex shape around the coupling hole 424.

カム型ヒンジ部420の結合孔424と作動ピン300のヒンジ孔312には、ヒンジピン340が滑動回転可能に挿入される。ヒンジピン340の組立性のために、ヒンジピン340の通過端部には固定ネジ350を締結する形で構成してもよい。   A hinge pin 340 is inserted into the coupling hole 424 of the cam-type hinge part 420 and the hinge hole 312 of the operating pin 300 so as to be slidable and rotatable. For assembly of the hinge pin 340, a fixing screw 350 may be fastened to a passing end portion of the hinge pin 340.

このように構成される本発明は、軸方向レバー400を杖の長さ方向に配置した形態であり、梃の作用をする軸方向レバー400の長さを必要なだけ長く延長することができ、軸方向レバー400の延長形態も力の作用方向に曲げられずに軸方向にまっすぐ延長した形態であるため、軸方向レバー400に作用した力が弧形把持片220,230に完全に伝達されるので、女性や高齢者も苦労せずにロック又は解除することができるように構成することができる。   The present invention configured as described above is a form in which the axial lever 400 is arranged in the length direction of the cane, and the length of the axial lever 400 acting as a heel can be extended as long as necessary. Since the extended form of the axial lever 400 is also a form extended straight in the axial direction without being bent in the acting direction of the force, the force acting on the axial lever 400 is completely transmitted to the arc-shaped gripping pieces 220 and 230. Therefore, it can be configured such that a woman or an elderly person can be locked or released without difficulty.

また、把持用チューブ200が上部弧形把持片220と下部弧形把持片230により上下に2つの半円形要素に分割される一方、軸方向レバー400のカムが径方向左右両側において作動ピン300を引いて上下部弧形把持片220,230を締める形態からなっているため、連結管4の外周面をバランスよく均一な力で圧迫することができ、ロック力も一層増大される。   In addition, the gripping tube 200 is divided into two semicircular elements up and down by the upper arc-shaped gripping piece 220 and the lower arc-shaped gripping piece 230, while the cam of the axial lever 400 moves the operating pin 300 on the left and right sides in the radial direction. Since the upper and lower arc-shaped gripping pieces 220 and 230 are pulled and tightened, the outer peripheral surface of the connecting pipe 4 can be pressed with a balanced and uniform force, and the locking force is further increased.

また、連結管4と接する上部弧形把持片220と下部弧形把持片230それぞれの円弧の長さが短く(従来の約半分水準)、ロック力を大きく加えても簡単に伸びないので、ロック力を十分に増大させることができ、耐久性も向上する。   In addition, the arc length of each of the upper arc-shaped gripping piece 220 and the lower arc-shaped gripping piece 230 in contact with the connecting pipe 4 is short (about half the conventional level) and does not easily extend even when a large locking force is applied. The force can be increased sufficiently and the durability is improved.

また、作動ピン300と押圧部224,234が径方向両側に配置される一方、カム面422が杖の長さ方向に回動する構造により、力の作用点が従来に比べて連結管2,4の中心軸により近く位置するようになってロック力をより一層増大させることができ、ロック力が増大しても押圧部224,234が変形するおそれがない。   In addition, the operating pin 300 and the pressing portions 224 and 234 are arranged on both sides in the radial direction, and the cam surface 422 rotates in the length direction of the cane, so that the action point of the force is the connecting pipe 2, The locking force can be further increased by being positioned closer to the central axis 4, and there is no possibility that the pressing portions 224 and 234 are deformed even if the locking force increases.

また、上部ピン310と調節ネジ320のネジ結合により作動ピン300の長さを増減させてロック力を調節することができる利便性がある。   Further, there is a convenience that the lock force can be adjusted by increasing or decreasing the length of the operating pin 300 by the screw connection of the upper pin 310 and the adjusting screw 320.

図7〜図10は本発明に係る杖のロック状態と解除状態を示した図である。図7〜図10を通じ、杖をロックし、解除する方法について簡略に説明する。   7 to 10 are views showing a locked state and a released state of the cane according to the present invention. A method of locking and releasing the cane will be briefly described with reference to FIGS.

まず、図7及び図8に示されたところのように、軸方向レバー400を持ち上げた状態では、カム型ヒンジ部420のカム面422が上部押圧部224から外れるようになって上下部押圧部224,234が元のとおり広げられ、上下部弧形把持片220,230と下部連結管4との間に隙間が生じて下部連結管4が自由となるため、上部連結管2内に下部連結管4を押し込んだり、引き抜いたりすることができる。   First, as shown in FIGS. 7 and 8, when the axial lever 400 is lifted, the cam surface 422 of the cam type hinge part 420 is detached from the upper pressing part 224, so 224 and 234 are expanded as they are, and a gap is created between the upper and lower arc-shaped gripping pieces 220 and 230 and the lower connecting pipe 4 so that the lower connecting pipe 4 becomes free. The tube 4 can be pushed in or pulled out.

図7及び図8において、軸方向レバー400を矢印方向(ロック方向)に回動させると、図9及び図10のような状態となる。すなわち、軸方向レバー400のカム面422が作動ピン300の中心軸と一致する状態で回転しながら作動ピン300を引いて上下押圧部224,234を狭め、それにより上下部弧形把持片220,230が下部連結管4の周囲を加圧してロックするようになる。   7 and 8, when the axial lever 400 is rotated in the arrow direction (locking direction), the state shown in FIGS. 9 and 10 is obtained. That is, while rotating with the cam surface 422 of the axial lever 400 coinciding with the central axis of the operating pin 300, the operating pin 300 is pulled to narrow the upper and lower pressing portions 224 and 234, thereby the upper and lower arc-shaped gripping pieces 220, 230 presses and locks the periphery of the lower connecting pipe 4.

図11は、本発明に係るロックを適用した杖の構成例を示した図である。   FIG. 11 is a diagram showing a configuration example of a cane to which the lock according to the present invention is applied.

図11に示されたところのように、杖は複数個の連結管2,4,6,…からなるが、隣り合う連結管のうち径が大きいものを“上部連結管”といい、径が小さいものを“下部連結管”という。   As shown in FIG. 11, the cane is composed of a plurality of connecting pipes 2, 4, 6,..., And the adjacent connecting pipe having a large diameter is called an “upper connecting pipe”. The smaller one is called the “lower connecting pipe”.

杖は、連結管の連結部のうち一つ以上の地点に、本発明に係るロック装置100を自由に適用していてもよい。図11のように、連結管が3段からなる場合には、1〜2段の上部連結管2と下部連結管4には本発明のロック装置100を適用し、2〜3段の上部連結管4と下部連結管6には、通常のボタン型ロック装置101を適用していてもよい。又は、1〜2段と2〜3段の連結部にいずれも本発明に係るロック装置100を適用していてもよい。   The cane may freely apply the locking device 100 according to the present invention to one or more points in the connecting portion of the connecting pipe. As shown in FIG. 11, when the connecting pipe has three stages, the locking device 100 of the present invention is applied to the upper and lower connecting pipes 2 and 4 of the first and second stages, and the upper connecting pipe of the second and third stages. A normal button type locking device 101 may be applied to the pipe 4 and the lower connecting pipe 6. Alternatively, the locking device 100 according to the present invention may be applied to any one of the first and second steps and the second and third steps.

図12〜図13は、本発明の他の実施例に係るロック装置を示すものであり、図12は斜視図、図13は緩み防止具を詳細に示した図面であり、図14は、緩み防止具を適用して組み立てた状態の断面図である。   FIGS. 12 to 13 show a locking device according to another embodiment of the present invention, FIG. 12 is a perspective view, FIG. 13 is a drawing showing a loosening prevention device in detail, and FIG. 14 is a loosening device. It is sectional drawing of the state assembled by applying a prevention tool.

本実施例は、前述した実施例と比べて作動ピン300の構成が異なり、作動ピン300を保持する緩み防止具500が付加された点が異なり、ヒンジピン340と固定ピン350aの結合の構成が異なる。それ以外の構成は前述した実施例と同一であるため、詳細な説明は省略する。   The present embodiment is different from the above-described embodiment in the configuration of the operating pin 300, is different in that a loosening prevention tool 500 for holding the operating pin 300 is added, and the configuration of the coupling of the hinge pin 340 and the fixing pin 350a is different. . Since other configurations are the same as those of the above-described embodiment, detailed description thereof is omitted.

緩み防止具500は、上部ピン310にネジ結合された調節ネジ320を拘束することにより、使用中に振動等により調節ネジ320が緩んで作動ピン300全体の長さが使用者の意思に反して増減される現象を防止するためのものである。   The loosening prevention device 500 restrains the adjustment screw 320 screwed to the upper pin 310, so that the adjustment screw 320 is loosened due to vibration or the like during use, and the entire length of the operation pin 300 is contrary to the intention of the user. This is to prevent the phenomenon to be increased or decreased.

図12に示されたところのように、緩み防止具500は、把持用チューブ200の下部押圧部234の上面に固定され、その内部に貫通する調節ネジ320の外周面を弾性力により保持し拘束するようになる。   As shown in FIG. 12, the loosening prevention device 500 is fixed to the upper surface of the lower pressing portion 234 of the gripping tube 200, and holds and restrains the outer peripheral surface of the adjusting screw 320 penetrating therethrough by an elastic force. Will come to do.

このとき、調節ネジ320の外周には、別途の溝部326を形成して緩み防止具500を容易に保持することができるようにしていてもよい。   At this time, a separate groove 326 may be formed on the outer periphery of the adjustment screw 320 so that the loosening prevention device 500 can be easily held.

緩み防止具500が把持用チューブ200の下部押圧部234の上面に固定される形態であり、本実施例においては、下部押圧部234の両横に緩み防止具500の両側面が挿入される挿入顎部238が形成される。   In this embodiment, the loosening prevention device 500 is fixed to the upper surface of the lower pressing portion 234 of the gripping tube 200. In this embodiment, both side surfaces of the loosening prevention device 500 are inserted on both sides of the lower pressing portion 234. A jaw 238 is formed.

本実施例のように緩み防止具500を適用した場合には、調節ネジ320にあえてワッシャ330(図5及び図6参照)を介在せずともよい。   When the loosening prevention device 500 is applied as in the present embodiment, the adjustment screw 320 may not be provided with the washer 330 (see FIGS. 5 and 6).

図13に示されたところのように、緩み防止具500は、ベース510と、前記ベース510の中間に形成されて、前記調節ネジ320の外周面を弾性加圧する複数の弾性片520を含む。弾性片520の弾性力を提供するために、弾性片520の一側には切欠孔530を形成していてもよい。   As shown in FIG. 13, the loosening prevention device 500 includes a base 510 and a plurality of elastic pieces 520 that are formed between the base 510 and elastically pressurize the outer peripheral surface of the adjusting screw 320. In order to provide the elastic force of the elastic piece 520, a notch hole 530 may be formed on one side of the elastic piece 520.

このような本実施例によれば、図14に示されたところのように、上部ピン310にネジ結合された調節ネジ320の外周面を緩み防止具500の複数の弾性片520が弾性加圧して調節ネジ320が任意に回転する現象を防止することができるので、使用者が調節ネジ320を調整しない限り、所定の長さに調節した状態を持続的に維持することができる。   According to this embodiment, as shown in FIG. 14, the plurality of elastic pieces 520 of the loosening prevention device 500 elastically pressurize the outer peripheral surface of the adjustment screw 320 screwed to the upper pin 310. Therefore, unless the adjustment screw 320 is adjusted by the user, a state where the adjustment screw 320 is adjusted to a predetermined length can be continuously maintained.

一方、図12及び図14に示された実施例においては、上部ピン310と軸方向レバー400をヒンジ結合するヒンジピン340に固定ピン350aが強制圧入された構成を有する。   On the other hand, the embodiment shown in FIGS. 12 and 14 has a configuration in which a fixing pin 350 a is forcibly press-fitted into a hinge pin 340 that hinges the upper pin 310 and the axial lever 400.

前述した実施例においては、図5及び図6において説明したように、ヒンジピン340に固定ネジ350をネジ結合した形態からなっているが、ネジ結合の代わりに、固定ピン350aにヒンジピン340を強引に圧入して結合する等、多様な構成を採用することができることを示す。   5 and 6, the fixing screw 350 is screwed to the hinge pin 340 as described in FIGS. 5 and 6, but the hinge pin 340 is forcibly attached to the fixing pin 350 a instead of screwing. It shows that various configurations such as press-fitting and joining can be adopted.
