Description

本発明は、挟持具に関するものであり、特に、洗濯の際に使用される洗濯ばさみ、或いは書類を挟む書類挟みやクリップ等として利用され、バネの弾性力を利用して物品を二方向から挟み込んで保持する挟持具に関するものである。   The present invention relates to a holding tool, and in particular, is used as a clothespin used in washing, or as a document clip or clip that holds a document, and uses an elastic force of a spring to move an article in two directions. It is related with the clamping tool pinched | interposed from and hold | maintained.

従来から、バネの弾性力を利用して物品を挟持する洗濯ばさみ等の挟持具が種々の分野及び用途において数多く用いられている。特に一般的な洗濯ばさみについて例示すると、一対の挟持片同士を軸部で軸支し、該挟持片の一端同士が近接するようにリング状のバネを利用して付勢するものが知られている。使用者は、挟持片の把持部を親指及び人差し指でそれぞれ把持し、バネの付勢力に抗する力を加えることにより、把持部同士を近接させる開操作を行う。その結果、軸部を支点として、挟持片の挟持部が互いに離間し、当該挟持部の間に物品(洗濯物等)を挿入することが可能な空間が生成される。そして、係る空間に物品を挿入し、把持部に加えている力を解除する。これにより、バネの弾性力によって再び挟持部同士が近接し、物品が挟持部で挟込まれた状態となる。   2. Description of the Related Art Conventionally, many holding tools such as clothespins that hold an article using the elastic force of a spring have been used in various fields and applications. In particular, a typical clothespin is exemplified by a pair of holding pieces that are pivotally supported by a shaft portion and biased using a ring-shaped spring so that one ends of the holding pieces are close to each other. It has been. The user grips the gripping portions of the sandwiching pieces with the thumb and forefinger, and performs an opening operation to bring the gripping portions closer by applying a force against the urging force of the spring. As a result, with the shaft portion as a fulcrum, the holding portions of the holding pieces are separated from each other, and a space in which an article (laundry or the like) can be inserted between the holding portions is generated. Then, the article is inserted into the space, and the force applied to the grip portion is released. As a result, the sandwiching portions come close again by the elastic force of the spring, and the article is sandwiched between the sandwiching portions.

ここで、上記の洗濯ばさみによる挟持は、テコの原理を応用したものであり、上記の場合、軸部が支点、挟持部が作用点、及び把持部が力点に相当する。なお、洗濯ばさみ以外にも、クリップや書類ばさみ、トング等の種々の挟持具は、同様にテコの原理を応用している。   Here, the holding by the clothespin is an application of the lever principle. In the above case, the shaft portion corresponds to the fulcrum, the holding portion corresponds to the action point, and the gripping portion corresponds to the force point. In addition to the clothespins, various holding devices such as clips, document shears, and tongs also apply the lever principle.

物品を挟持具で挟持する場合、上述のように親指及び人差し指等によって、一対の把持部同士を近接させるようにバネの付勢力に抗する力を加える必要がある。そのため、指先の力の弱い高齢者等にとっては、この開操作を安定して行えない場合があった。さらに、挟持部同士を離間させた状態を保ちながら、その間の空間に物品を挿入する場合、一般に挟持具を把持した反対側の手で、物品を把持し、当該空間に挿し入れる動作を行うことがあった。すなわち、これらの物品の挟持動作は、原則的に両手を使用して行うものであった。   When the article is clamped with a clamping tool, it is necessary to apply a force against the biasing force of the spring so that the pair of gripping parts are brought close to each other with the thumb and the index finger as described above. For this reason, there are cases where the opening operation cannot be performed stably for elderly people with weak fingertips. Furthermore, when inserting an article into a space between them while maintaining the state where the sandwiching parts are separated from each other, generally holding the article with the opposite hand that grasps the sandwiching tool and inserting the article into the space was there. That is, the holding operation of these articles is basically performed using both hands.

これに対し、挟持動作を安定して行うことを目的として、例えば、ピンチ本体(挟持片)を軸支した軸部(支点)の両側にバネ支持駒を設け、当該バネ支持駒に装着したリング状バネの弾性力が作用する付勢位置(作用点)を変化させることにより、挟持具を開状態または閉状態のいずれか一方に操作に応じて付勢することが可能な技術が既に開示されている(特許文献1参照)。係る構成により、支点よりも前側(挟持部側)に弾性力が付勢される場合、通常の洗濯ばさみ等のように挟持部同士が近接するような作用を奏し、一方、支点よりも後側(把持部側)に弾性力が付勢される場合、挟持部同士を離間するような作用をすることとなる。その結果、挟持部の近接及び離間の各状態が、片手の操作で楽に行うことが可能となる。そのため、高齢者や片手の不自由な人であっても挟持動作を確実に行うことができる。   On the other hand, for the purpose of stably performing the clamping operation, for example, a ring provided with spring support pieces on both sides of a shaft portion (fulcrum) that pivotally supports a pinch body (clamping piece) and attached to the spring support piece A technique has already been disclosed that can urge the holding tool to either the open state or the closed state by changing the urging position (action point) at which the elastic force of the cylindrical spring acts. (See Patent Document 1). With such a configuration, when the elastic force is biased to the front side (holding part side) from the fulcrum, it acts to bring the holding parts close to each other like a normal clothespin, etc. When the elastic force is urged to the rear side (the gripping part side), it acts to separate the clamping parts. As a result, it is possible to easily perform the proximity and separation states of the sandwiching portion with one-handed operation. Therefore, even an elderly person or a handicapped person can surely perform the clamping operation.

上記に示したように、一般的な洗濯ばさみ等の挟持具の場合、片手の不自由な人、或いは指先の力の弱い高齢者にとっては、安定した挟持動作を行うことができないケースがあった。これに対し、軸部(支点)の近傍にバネ支持駒を設けたものは、リング状バネの弾性力が作用する付勢位置を支点の前後に変化させることができ、挟持動作を比較的容易に行うことが可能である。しかしながら、支点に対する付勢位置の変化は、非常に僅かであり、ピンチ本体に力が加わると、いずれか一方に付勢されたリング状バネの付勢が容易に解除される可能性が高かった。このため、挟持動作の途中で付勢方向が変化し、元の状態(挟持部同士が近接した状態)に戻ることがあり、反って作業効率が低下することがあった。   As shown above, in the case of a holding tool such as a general clothespin, there are cases where a stable holding operation cannot be performed for a handicapped person or an elderly person with weak fingertip power. there were. On the other hand, in the case where a spring support piece is provided in the vicinity of the shaft (fulcrum), the biasing position where the elastic force of the ring-shaped spring acts can be changed before and after the fulcrum, and the clamping operation is relatively easy. Can be done. However, the change in the biasing position with respect to the fulcrum was very slight, and when a force was applied to the pinch body, the bias of the ring-shaped spring biased to either one was likely to be released easily. . For this reason, the urging direction may change during the clamping operation, and may return to the original state (a state in which the clamping parts are close to each other), which may cause a reduction in work efficiency.

また、従来の挟持具の場合、物品等を挟持する挟持部と挟持部の開動作及び閉動作を行う把持部(操作部)に係る構成は、それぞれ別々の形状で形成され、単一の機能しか有していなかった。そのため、物品等を挟持する際に、使用者は挟持具の把持部の位置及び向きを留意して把持し、物品等に挟持部を向けて挟持動作をする必要があった。したがって、仮に挟持部側を把持した場合には、挟持具を把持する方向を持ち替える動作が必要となり、係る持ち替え動作を煩わしく感じる使用者もあった。すなわち、いずれの方向(挟持部側及び把持部)からでも挟持可能な挟持具はこれまでに開発されていなかった。   In the case of a conventional clamping tool, the configuration related to the clamping unit that clamps an article or the like and the gripping unit (operation unit) that performs the opening and closing operations of the clamping unit are formed in different shapes, and have a single function. Had only. Therefore, when sandwiching an article or the like, the user needs to grasp the position and orientation of the gripping portion of the sandwiching tool, and perform a clamping operation with the clamping portion facing the article or the like. Therefore, if the holding part side is gripped, an operation of changing the direction in which the holding tool is held is necessary, and there are some users who feel that the holding operation is troublesome. That is, a clamping tool that can be clamped from any direction (the clamping part side and the gripping part) has not been developed so far.

そこで、本発明は上記実情に鑑み、片手での物品等の挟持動作を安定して行うことができ、さらに挟持方向を合わせるための持ち替え動作を必要とすることがない、挟持具の提供を課題とするものである。   Therefore, in view of the above circumstances, the present invention provides a holding tool that can stably hold an article or the like with one hand and does not require a holding action for adjusting the holding direction. It is what.

上記の課題を解決するため、本発明の挟持具は、「把持部及び挟持部を有し、互いに対向するように配した対向面に凹状の当接面を有する移動規制部を備える一対の挟持片と、一対の前記挟持片の間に介設され、前記挟持片の長手方向に沿って周面を前記当接面に当接させながら前記移動規制部による規制範囲を移動可能な移動軸部と、前記移動軸部を介設した状態で、一対の前記挟持片の互いの挟持部を近接させた挟持位置及び離間させた挟持解除位置に、前記移動軸部の移動による支点変化に応じて弾性力の付与方向を変化させてそれぞれ付勢する弾性付勢手段と」を具備するものから主に構成されている。   In order to solve the above-described problem, the clamping device of the present invention has a pair of clamping devices including a movement restricting portion having a gripping portion and a clamping portion and having a concave contact surface on opposing surfaces arranged to face each other. A moving shaft portion that is interposed between a piece and a pair of the holding pieces and can move within a restriction range by the movement restriction portion while bringing a peripheral surface into contact with the contact surface along a longitudinal direction of the holding piece And in a state where the moving shaft portion is interposed, a pair of the holding pieces are moved to a holding position where the holding portions are brought close to each other and a holding release position where they are separated from each other according to a fulcrum change due to the movement of the moving shaft portion. It is mainly comprised from what comprises the elastic urging means which urges | biases each by changing the provision direction of an elastic force.

ここで、挟持片とは、端部にそれぞれ把持部及び挟持部を有する長手形状の部材によって構成されたものであり、凹状に形成された当接面を有する移動規制部を備えるものである。これにより、後述する移動軸部は、凹状の移動規制部の端から端までを移動することが可能となる。なお、挟持片の素材は特に限定されないが、金属或いは樹脂等の硬質の素材によって形成することが好適である。   Here, the sandwiching piece is composed of a long member having a gripping part and a sandwiching part at the end part, and includes a movement restricting part having a contact surface formed in a concave shape. Thereby, the moving shaft part described later can move from end to end of the concave movement restricting part. The material of the sandwiching piece is not particularly limited, but it is preferable to form it with a hard material such as metal or resin.

一方、移動軸部は、略円柱形状を呈するものであって、周面を移動規制部の当接面に当接した状態で滑動或いは一部は回動しながら、移動規制部の端から端まで移動するものである。ここで、互いに対向面を対向させた状態で配設された一対の挟持片に挟まれた状態で上記移動がなされるため、移動規制部によって規制された規制範囲(端から端まで)を越えて、挟持片の長手方向に沿って移動することができない。なお、移動軸部の大きさは、特に限定されないが、挟持片の厚さに対して数倍程度に形成され、移動規制部の凹み(深さに相当)よりも大きな軸径を有する必要がある。これにより、移動軸部を介設した一対の挟持片とによって、挟持部同士(または把持部同士)が近接すると略三角形状を呈するようになる。   On the other hand, the moving shaft portion has a substantially cylindrical shape, and slides or partially rotates while the peripheral surface is in contact with the abutting surface of the movement restricting portion, and ends from the end of the movement restricting portion. To move up to. Here, since the above movement is performed while being sandwiched between a pair of sandwiching pieces arranged with the opposing surfaces facing each other, the regulation range (from end to end) regulated by the movement regulating unit is exceeded. Thus, it cannot move along the longitudinal direction of the sandwiching piece. In addition, although the magnitude | size of a moving shaft part is not specifically limited, It is formed about several times with respect to the thickness of a clamping piece, and needs to have a shaft diameter larger than the dent (equivalent to the depth) of a movement control part. is there. As a result, when the sandwiching portions (or the gripping portions) come close to each other by the pair of sandwiching pieces with the moving shaft portion interposed therebetween, a substantially triangular shape is exhibited.

一方、弾性付勢手段とは、各挟持片に弾性力を付与することが可能なものであり、従来から使用されているリング状バネ、スプリング等の弾性部材を適宜使用することができる。これにより、バネ等の弾性力を利用して挟持片を所定方向に付勢することが可能となる。   On the other hand, the elastic urging means is capable of applying an elastic force to each clamping piece, and conventionally used elastic members such as ring springs and springs can be appropriately used. Thereby, it becomes possible to urge the holding piece in a predetermined direction using an elastic force such as a spring.

したがって、本発明の挟持具によれば、挟持片に設けられた移動規制部に沿って移動軸部が移動可能に形成されている。そのため、挟持具における開閉動作の支点が移動軸部の移動によって変化することとなる。これにより、把持部同士を近接させ、挟持部同士を離間させる動作(開操作)を行うことによって、移動軸部は移動規制部の当接面と周面を当接させながら挟持部側に押出され、支点が挟持部側に移動する。このとき、凹状に形成された移動規制部によって移動軸部の移動は所定範囲に規制される。その結果、弾性付勢手段による弾性力が付勢される付勢位置が、移動移動軸と把持部の間に変化し、把持部同士を近接させる(挟持部同士を離間させる)ように作用する。その結果、挟持部同士が離間した状態が保持される(挟持解除位置に相当)。   Therefore, according to the holding tool of the present invention, the moving shaft portion is formed to be movable along the movement restricting portion provided on the holding piece. Therefore, the fulcrum of the opening / closing operation in the holding tool changes as the moving shaft portion moves. As a result, by moving the gripping parts close to each other and separating the holding parts (opening operation), the moving shaft part is pushed out to the holding part side while bringing the contact surface of the movement restricting part into contact with the peripheral surface. Then, the fulcrum moves to the clamping part side. At this time, the movement of the moving shaft portion is restricted to a predetermined range by the movement restricting portion formed in a concave shape. As a result, the urging position where the elastic force by the elastic urging means is urged changes between the moving movement shaft and the gripping part, and acts so that the gripping parts are brought close to each other (the clamping parts are separated from each other). . As a result, the state where the sandwiching portions are separated from each other is maintained (corresponding to the sandwiching release position).

一方、挟持部同士が離間した状態から挟持部を近接させる閉操作を行うことに移動軸部は、上記と逆の動きによって把持部側に押出され、支点が把持部側に移動する。その結果、弾性付勢手段による弾性力が付勢される付勢位置が、移動軸と挟持部の間に変化し、挟持部同士を近接させる(把持部同士を離間させる)ように作用する。これにより、挟持部同士が近接した状態が保持される(挟持位置に相当)。   On the other hand, the moving shaft is pushed to the gripping part side by the reverse movement to perform the closing operation to bring the gripping parts close to each other from the state where the gripping parts are separated from each other, and the fulcrum moves to the gripping part side. As a result, the urging position where the elastic force by the elastic urging means is urged changes between the moving shaft and the clamping part, and acts so that the clamping parts are brought close to each other (the gripping parts are separated from each other). Thereby, the state in which the clamping parts are close to each other is held (corresponding to the clamping position).

すなわち、移動規制部に沿って移動軸部が移動することによって、弾性力によって付勢する付勢位置が支点の前後で移動することになり、弾性付勢手段の付勢方向が変化する。その結果、使用者の任意の状態(挟持位置・挟持解除位置)にそれぞれ変位させることが容易に可能となり、係る状態を保持することができる。   That is, when the moving shaft moves along the movement restricting portion, the urging position urged by the elastic force moves before and after the fulcrum, and the urging direction of the elastic urging means changes. As a result, it is possible to easily displace the user to any state (clamping position / clamping release position), and the state can be maintained.

さらに、本発明の挟持具は、上記構成に加え、「前記移動軸部及び前記移動規制部の少なくとも一方は、前記移動軸部の移動を前記挟持片の長手方向に限定して規制する方向規制手段を」具備するものであっても構わない。   Further, in addition to the above-described configuration, the clamping device of the present invention may be configured such that “at least one of the moving shaft portion and the movement restricting portion restricts movement of the moving shaft portion to a longitudinal direction of the sandwiching piece. It may be provided with “means”.

したがって、本発明の挟持具によれば、移動軸部の移動を挟持片の長手方向に限定的に規制する方向規制手段を有している。これにより、挟持具を開閉させる動作を行う際の所謂「軸ぶれ」の発生を抑え、挟持具の開閉が安定したものとなる。ここで、方向規制手段としては、例えば、円柱形状の移動軸部に挟持片の横幅方向に合致するように一対のフランジを設け、係るフランジによって移動方向をガイドするものや、或いは挟持片の移動規制部の当接面に長手方向に沿って溝部または凸部を設け、一方の移動軸部の周面に当接面の溝部等に対応する凸部または溝部を設け、係る構成によって摺動可能としたものを示すことができる。これにより、挟持片の長手方向に沿った移動軸部の動きが安定して規制される。   Therefore, according to the sandwiching tool of the present invention, it has the direction restricting means for restricting the movement of the moving shaft part in the longitudinal direction of the sandwiching piece. This suppresses the occurrence of so-called “shaking of shaft” when performing the operation of opening and closing the holding tool, and the opening and closing of the holding tool becomes stable. Here, as the direction regulating means, for example, a pair of flanges are provided on the cylindrical moving shaft portion so as to match the lateral width direction of the sandwiching piece, and the moving direction is guided by the flange, or the movement of the sandwiching piece A groove or protrusion is provided along the longitudinal direction on the contact surface of the restricting portion, and a protrusion or groove corresponding to the groove or the like of the contact surface is provided on the peripheral surface of one of the moving shaft portions. Can be shown. Thereby, the movement of the moving shaft part along the longitudinal direction of the clamping piece is stably regulated.

さらに、本発明の挟持具は、上記構成に加え、「前記移動規制部の前記当接面は、略中央部が上方に突出した山部、及び前記山部の両側に設けられ、凹状に湾曲した一対に谷部を有して形成される」ものであっても構わない。   Further, in addition to the above-described configuration, the clamping device of the present invention may be configured so that “the contact surface of the movement restricting portion is provided on a mountain portion with a substantially central portion protruding upward, and on both sides of the mountain portion, and is curved in a concave shape. It may be formed with a trough portion in a pair.

したがって、本発明の挟持具によれば、当接面の略中央部が上方に突出した山部及び該山部の両側に凹状に湾曲した一対の谷部が形成されている。これにより、移動軸部が当接面に沿って谷部から谷部に向かって移動する場合、略中央部に設けられた山部を超える必要がある。すなわち、移動軸部が山部を超えるためには、弾性力に抗するとともに、さらに強い力で把持部等を近接させるような動作が必要となる。その結果、山部を境界として弾性付勢手段の付勢方向を変化させることができる。なお、山部及び谷部の間の連結は、移動軸部の移動が安定するように滑らかな曲面で形成されている。   Therefore, according to the holding tool of the present invention, the crest portion where the substantially central portion of the abutting surface protrudes upward and the pair of trough portions curved in a concave shape are formed on both sides of the crest portion. Thereby, when a moving shaft part moves toward a trough part from a trough part along a contact surface, it is necessary to exceed the peak part provided in the approximate center part. That is, in order for the moving shaft portion to exceed the peak portion, it is necessary to operate against the elastic force and bring the gripping portion and the like closer together with a stronger force. As a result, the urging direction of the elastic urging means can be changed with the peak portion as a boundary. In addition, the connection between a peak part and a trough part is formed in the smooth curved surface so that the movement of a moving shaft part may be stabilized.

さらに、本発明の挟持具は、上記構成に加え、「前記挟持片は、前記移動規制部を中心に左右対称形状に設けられ、前記挟持片の両端がそれぞれ前記把持部及び前記挟持部の双方の機能を奏する」ものであっても構わない。   Further, in addition to the above-described configuration, the sandwiching tool of the present invention includes: “The sandwiching piece is provided in a symmetrical shape with the movement restricting portion as a center, and both ends of the sandwiching piece are both the gripping portion and the sandwiching portion, respectively. It is also possible to have a function of

したがって、本発明の挟持具によれば、挟持片が左右対称形状に形成され、挟持片のそれぞれの両端が把持部及び挟持部のいずれとしても機能するようになっている。そのため、移動軸部を移動させ、支点を変化させることにより、挟持具の持替え動作を行う必要がなく、物品等を挟持する動作を行うことが可能となる。   Therefore, according to the holding tool of the present invention, the holding piece is formed in a symmetrical shape, and both ends of the holding piece function as both the gripping part and the holding part. Therefore, by moving the moving shaft portion and changing the fulcrum, it is not necessary to perform a holding tool changing operation, and an operation for holding an article or the like can be performed.

さらに、本発明の挟持具は、上記構成に加え、「前記移動軸部は、前記周面を有する一対の円盤状部材と、一対の前記円盤状部材を互いに離間させた状態で、前記円盤状部材の軸心を連結する連結部とを具備して構成され、前記弾性付勢手段は、一対の前記挟持片の前記挟持部が前記挟持位置または前記挟持解除位置のいずれか一方にあるとき、前記円盤状部材同士が離間して連結されたことによって形成された空隙に、少なくとも一部が収容される」ものであっても構わない。   Furthermore, the clamping device of the present invention has the above-described configuration, in which “the moving shaft portion is formed of the disk-shaped member in a state where the pair of disk-shaped members having the peripheral surface and the pair of disk-shaped members are separated from each other. A connecting portion that connects the shaft centers of the members, and the elastic biasing means is configured such that when the sandwiching portions of the pair of sandwiching pieces are in either the sandwiching position or the sandwiching release position, The disk-shaped members may be at least partially accommodated in a gap formed by connecting the disk-shaped members apart from each other.

したがって、本発明の挟持具によれば、移動軸部を一対の円盤状部材及びこれを連結する連結部によって構成することにより、一対の円盤状部材の間に空隙が形成される。そして、弾性付勢手段(例えば、バネ)の一部が係る空隙に開操作若しくは閉操作時に収容される。これにより、特に、左右対称形状となるように一対の挟持片を構成し、いずれの方向からでも挟持可能に挟持具を構成した場合、上記バネが挟持動作または把持動作に邪魔になることがない。   Therefore, according to the holding tool of the present invention, the moving shaft portion is constituted by the pair of disk-shaped members and the connecting portion that connects the pair of disk-shaped members, whereby a gap is formed between the pair of disk-shaped members. A part of the elastic urging means (for example, a spring) is accommodated in the gap in the opening operation or the closing operation. Thereby, in particular, when the pair of clamping pieces are configured to have a symmetrical shape and the clamping tool is configured to be clamped from any direction, the spring does not interfere with the clamping operation or the gripping operation. .

さらに、本発明の挟持具は、上記構成に加え、「前記移動軸部は、前記挟持片の長手方向に沿った移動を禁止及び解除する移動禁止解除手段を」具備するものであっても構わない。   Furthermore, in addition to the above-described configuration, the clamping device of the present invention may include “the movement shaft portion includes a movement prohibition releasing unit that prohibits and cancels the movement of the clamping piece along the longitudinal direction”. Absent.

したがって、本発明の挟持具によれば、移動軸部の移動を禁止及び解除する移動禁止解除手段を設けることによって、移動を禁止した状態では通常の洗濯ばさみ等の一般的な挟持具としての使用が可能であり、一方、移動を解除した状態では上記に示した優れた機能を有する挟持具としての機能を奏させることが可能となる。   Therefore, according to the holding tool of the present invention, by providing a movement prohibition releasing means for prohibiting and releasing the movement of the moving shaft portion, as a general holding tool such as a normal clothespin in a state where movement is prohibited On the other hand, in the state where the movement is released, the function as the holding tool having the excellent function described above can be exhibited.

さらに、本発明の挟持具は、上記構成に加え、「前記移動禁止解除手段は、楕円形状を呈し、互いに離間して前記移動軸部に配設された一対のフランジと、前記フランジのフランジ周面と略一致し、嵌合可能に形成された一対のフランジ受孔及び前記フランジ受孔の間を連結する連結接面を有し、前記挟持片の挟持側壁に前記フランジのフランジ厚と略一致する深さで設けられた摺動溝部とをさらに具備し、互いに対向した一対の前記挟持片の間に、前記フランジ受孔及び前記フランジを嵌合させることにより、前記移動軸部の前記挟持片の長手方向に沿った移動を禁止するとともに、楕円形状の前記フランジを前記フランジ受孔の嵌合状態から解除することにより、前記移動軸部の前記挟持片の長手方向に沿った移動を解除する」ものであっても構わない。   In addition to the above-described structure, the clamping device of the present invention may include: “The movement prohibition releasing means has an elliptical shape and is spaced apart from each other and disposed on the moving shaft portion, and a flange periphery of the flange. A pair of flange receiving holes formed so as to be able to fit with each other and a connecting contact surface for connecting between the flange receiving holes, the holding side wall of the holding piece substantially matches the flange thickness of the flange And a sliding groove provided at a depth to be engaged, and the flange receiving hole and the flange are fitted between a pair of the holding pieces opposed to each other, whereby the holding piece of the moving shaft portion The movement along the longitudinal direction of the clamping piece of the moving shaft portion is released by prohibiting the movement along the longitudinal direction of the flange and releasing the elliptical flange from the fitting state of the flange receiving hole. ” And it may be.

したがって、本発明の挟持具によれば、フランジ及び当該フランジ周面の形状に合致するフランジ受孔に係る構成によって、フランジ及びフランジ受孔の嵌合状態によって移動軸部の移動を禁止及び解除することが可能となる。すなわち、挟持片に介設された移動軸部を係る介設状態で、例えば、90度回転させることにより、フランジとフランジ受孔との嵌合状態が変化する。ここで、フランジ及びフランジ受孔が嵌合状態となっている場合、挟持片の把持部同士を近接させるように力を加えても、フランジの周面とフランジ受孔の孔壁とが摺動し、係る部位が軸として作用する。その結果、通常の挟持具(洗濯ばさみ等)のように軸が変位することがない。一方、フランジ及びフランジ受孔の嵌合状態を解除した場合(90度回転の場合)、把持部同士を近接させる動作をすることにより、当該移動軸部が挟持片の長手方向に沿って移動し、軸の変位が生じる。これにより、上記示したように、挟持具による弾性部材による付勢方向が変化することが可能となる。   Therefore, according to the holding tool of the present invention, the configuration of the flange and the flange receiving hole that matches the shape of the peripheral surface of the flange prohibits and releases the movement of the moving shaft portion depending on the fitting state of the flange and the flange receiving hole. It becomes possible. That is, when the moving shaft portion interposed in the clamping piece is in the interposed state, for example, the fitting state between the flange and the flange receiving hole is changed by rotating 90 degrees. Here, when the flange and the flange receiving hole are in the fitted state, even if a force is applied so that the gripping portions of the holding pieces are brought close to each other, the flange peripheral surface and the flange receiving hole hole wall slide. However, such a part acts as an axis. As a result, the shaft is not displaced like a normal holding tool (such as a clothespin). On the other hand, when the fitting state of the flange and the flange receiving hole is released (in the case of 90 ° rotation), the moving shaft portion moves along the longitudinal direction of the holding piece by moving the gripping portions closer to each other. A displacement of the shaft occurs. Thereby, as shown above, the urging direction by the elastic member by the clamping tool can be changed.

本発明の効果として、挟持片に沿って移動する移動軸部を有することにより、一対の挟持片の開動作及び閉動作によって支点を移動することができる。その結果、弾性付勢手段を利用して付勢方向を切り換え、挟持部を挟持位置及び挟持解除位置のいずれかに付勢することができる。加えて、挟持片がそれぞれ左右対称形に形成されていることにより、それぞれの両端が挟持部または把持部として機能することができ、把持する持ち手を替えることなく挟持動作を行うことが可能となる。さらに、移動規制部の当接面に設けられた山部によって、把持部同士を近接させる或いは把持部同士を離間させる動作を途中で止めることができ、通常の洗濯ばさみ等の挟持具と略同一の操作が可能であるとともに、係る山部によって弾性付勢手段の付勢方向の境界を決定することができる。   As an effect of the present invention, the fulcrum can be moved by the opening operation and the closing operation of the pair of holding pieces by having the moving shaft portion that moves along the holding pieces. As a result, the urging direction can be switched using the elastic urging means, and the nip portion can be urged to either the nip position or the nip release position. In addition, since the sandwiching pieces are formed symmetrically, the both ends can function as a sandwiching part or a gripping part, and a sandwiching operation can be performed without changing the gripping handle. Become. In addition, the crest provided on the contact surface of the movement restricting portion can stop the operation of bringing the gripping portions close to each other or separating the gripping portions on the way, and a holding tool such as a normal clothespin Substantially the same operation is possible, and the boundary in the urging direction of the elastic urging means can be determined by such a mountain portion.

Here, FIG. 1 is a perspective view showing the configuration of the clamping tool 1 of the first embodiment, FIG. 2 is an exploded perspective view showing the configuration of the clamping tool 1, and FIG. 3 is (a) a clamping position CP, ( It is explanatory drawing which shows the state of each clamping tool 1 in the middle of operation | movement, and (c) clamping cancellation | release position DP. Here, the clamping tool 1 of 1st embodiment shall illustrate and demonstrate what was the aspect of the clothespin.

第一実施形態の挟持具1は、図1乃至図3に示すように、一対の挟持片2a,2bと、該挟持片2a,2bの間に挟込んで介設した略円柱形状を呈する移動軸部3と、移動軸部3を介設した状態でそれぞれの挟持片2a,2bを所定方向に弾性力を利用して付勢する弾性バネ5とを主に具備して構成されている。ここで、弾性バネ5が本発明の弾性付勢手段に相当する。   As shown in FIGS. 1 to 3, the holding tool 1 of the first embodiment has a pair of holding pieces 2 a and 2 b and a movement having a substantially cylindrical shape interposed between the holding pieces 2 a and 2 b. The shaft 3 is mainly provided with an elastic spring 5 that urges each of the sandwiching pieces 2a and 2b in a predetermined direction using an elastic force with the moving shaft 3 interposed therebetween. Here, the elastic spring 5 corresponds to the elastic biasing means of the present invention.

さらに詳細に説明すると、一対の挟持片2a,2bは、それぞれ長手形状を呈し、中央部近傍に設けられた移動規制部6を中心として左右対称形(図3における紙面左右方向に相当)になるように構成されている。ここで、挟持片2a,2bのそれぞれの両端は、斜め方向に曲折され、物品等を挟持する際の挟持部7及び挟持具1の開閉動作を行う際に力を加える把持部4としての双方の機能を有している。なお、挟持片2a,2bの挟持部7側は、互いに対向する挟持部7同士が近接した際に挟持面同士が面接触するように、角に対して面取り加工が施されている。   More specifically, each of the pair of sandwiching pieces 2a and 2b has a longitudinal shape and is symmetrical with respect to the movement restricting portion 6 provided in the vicinity of the center portion (corresponding to the left and right direction on the paper surface in FIG. 3). It is configured as follows. Here, both ends of each of the holding pieces 2a and 2b are bent in an oblique direction, and both the holding portion 7 when holding an article or the like and the holding portion 4 that applies force when the holding tool 1 is opened and closed. It has the function of In addition, the clamping part 7 side of the clamping pieces 2a and 2b is chamfered with respect to the corners so that the clamping surfaces come into surface contact with each other when the opposing clamping parts 7 come close to each other.

そして、互いの挟持片2a,2bを対向するように配した対向面9には、凹状に切削加工された当接面10を有する移動規制部6が設けられている。なお、移動規制部6の長さ及び深さは、一対の挟持片2a,2bにおいて同一となるように形成されている。さらに詳述すると、当接面10は、中央部が上方に向かって突設された山部11として形成され、当該山部11の両側に凹状に湾曲して形成された谷部12が設けられている。なお、後述する移動軸部3の移動を安定して行うために、山部11及び谷部12のそれぞれの当接面10及び境界付近は平滑された曲面によって形成されている。   And the movement restriction | limiting part 6 which has the contact surface 10 cut into the concave shape is provided in the opposing surface 9 which distribute | arranged so that mutual clamping piece 2a, 2b might oppose. The length and depth of the movement restricting portion 6 are formed to be the same in the pair of sandwiching pieces 2a and 2b. More specifically, the contact surface 10 is formed as a peak portion 11 with a central portion projecting upward, and a trough portion 12 is provided on both sides of the peak portion 11 so as to be curved in a concave shape. ing. In addition, in order to perform the movement of the moving shaft part 3 to be described later stably, the contact surface 10 and the boundary vicinity of each of the peak part 11 and the valley part 12 are formed by smooth curved surfaces.

加えて、挟持片2a,2bは、移動規制部6の設けられた対向面9に相対する挟持片外面13に弾性バネ5の端部(バネ端部21)が挿入され、固定するためのバネ孔14が挟持片2a,2bの中央部に穿設されている。係る位置で、弾性バネ5の弾性力を受けることができる。すなわち、係るバネ孔14の付勢位置に相当する。なお、バネ孔14に各バネ端部21を挿入し、一対の挟持片2a,2bを所定方向に付勢するために、対向面9及び挟持片外面13を貫通する貫通孔15が設けられ、係る貫通孔15に弾性バネ5の一部が挿入されている。なお、挟持片2a,2bを構成する素材は、特に限定されないが、本実施形態ではアルミニウム素材を使用し、これを所望の形状に切削加工したものを使用している。   In addition, the sandwiching pieces 2a and 2b are springs for fixing the end portion (spring end portion 21) of the elastic spring 5 inserted into the sandwiching piece outer surface 13 facing the facing surface 9 provided with the movement restricting portion 6. A hole 14 is formed at the center of the sandwiching pieces 2a and 2b. At such a position, the elastic force of the elastic spring 5 can be received. That is, it corresponds to the biasing position of the spring hole 14. In addition, in order to insert each spring end portion 21 into the spring hole 14 and urge the pair of sandwiching pieces 2a and 2b in a predetermined direction, a through hole 15 penetrating the opposing surface 9 and the sandwiching piece outer surface 13 is provided. A part of the elastic spring 5 is inserted into the through hole 15. In addition, although the raw material which comprises the clamping pieces 2a and 2b is not specifically limited, In this embodiment, the aluminum raw material is used and what cut this into the desired shape is used.

一方、移動軸部3は、上述した移動規制部6の当接面10と当接する周面16を有する一対の円盤状部材17と、円盤状部材17を所定間隔だけ離間した状態で円盤状部材17の軸心をそれぞれ連結する連結部19とを具備して構成されている。さらに、移動軸部3は、円盤状部材17の最外側にそれぞれ円盤状部材17の直径よりも大きな直径で形成されたフランジ20が方向規制手段として設けられている。ここで、一対の円盤状部材17及びこれを連結した連結部19によって形成された移動軸部3の軸幅は、挟持片2a,2bの横幅方向(図3における紙面前後方向に相当)に略一致するように形成されている。そのため、上記構成を備えることにより、フランジ20が挟持片2a,2bの長手方向に沿って移動する移動軸部3の移動方向をガイドする機能を有することになる。その結果、移動軸部3の移動方向が規制され、安定したものとなる。ここで、移動軸部3を構成する素材は、特に限定されないが、本実施形態では、硬質の樹脂部材を使用し、これを所望の形状に切削加工したものを使用している。   On the other hand, the moving shaft portion 3 includes a pair of disc-like members 17 having a peripheral surface 16 that abuts on the abutment surface 10 of the movement restricting portion 6 and a disc-like member in a state where the disc-like members 17 are separated by a predetermined interval. And 17 connecting shafts 19 respectively. Further, the moving shaft portion 3 is provided with flanges 20 each having a diameter larger than the diameter of the disk-like member 17 on the outermost side of the disk-like member 17 as direction restricting means. Here, the axial width of the moving shaft portion 3 formed by the pair of disk-shaped members 17 and the connecting portion 19 connecting them is substantially the horizontal width direction of the sandwiching pieces 2a and 2b (corresponding to the front-rear direction of the drawing in FIG. 3). It is formed to match. Therefore, by providing the above-described configuration, the flange 20 has a function of guiding the moving direction of the moving shaft portion 3 that moves along the longitudinal direction of the sandwiching pieces 2a and 2b. As a result, the moving direction of the moving shaft portion 3 is restricted and becomes stable. Here, although the material which comprises the moving shaft part 3 is not specifically limited, In this embodiment, the hard resin member is used and what cut this into the desired shape is used.

弾性力によって挟持片2a,2bを付勢する弾性バネ5は、前述のバネ孔14に挿入し、取設可能なバネ端部21をそれぞれ有し、一対のバネ端部21の間を複数回曲折することにより、中央部を凸状に膨出させた膨出部22(図2参照)を有して形成されている。係る形状により、バネ端部21を互いに近接させる方向に弾性力が作用するようになっている。   The elastic springs 5 that urge the clamping pieces 2a and 2b by elastic force have spring end portions 21 that can be inserted into the above-described spring holes 14 and can be installed, and a plurality of times between the pair of spring end portions 21 are provided. By being bent, it is formed with a bulging portion 22 (see FIG. 2) in which the central portion bulges into a convex shape. With such a shape, an elastic force acts in a direction in which the spring end portions 21 are brought close to each other.

上記構成を用い、組立てることによって本実施形態の挟持具1が構築されている。具体的に示すと、まず、一対の挟持片2a,2bの挟持片外面14にそれぞれ設けられたバネ孔14に弾性バネ5のバネ端部21を挿入し、固定する。そして、一対の挟持片2a,2bの間に略円柱形状の移動軸部3を挿入する。このとき、上述の弾性バネ5によって一対の挟持片2a,2bの間隔は、移動軸部3の軸径(円盤状部材の直径に相当)よりも狭くなっている。そのため、弾性バネ5の弾性力に抗し、上記間隔を広げるようにして挿入する必要がある。これにより、移動規制部6の当接面10の一方の谷部12の間に移動軸部3が挿入され、移動軸部3の周面16と移動規制部6の当接面10が当接した状態となる。ここで、移動軸部3が挟持部7から遠い側の谷部12の間に位置するように設定することで、挟持部7同士が近接した状態となる(挟持位置CP:図3(a)参照)。なお、弾性バネ5による付勢位置は、移動軸部3よりも前方向(図3における紙面左方向)、換言すれば、移動軸部3と挟持部7との間に位置している。これにより、図1等に示すように、一対の挟持片2a,2bと移動軸部3によって略三角形形状を呈する挟持位置CPにある挟持具1が生成される。ここで、移動軸部3の一対の円盤状部材17が互いに離間することによって形成された空隙23に、曲折された弾性バネ5の膨出部22の一部が収容されている。これにより、弾性バネ5によって、一対の挟持片2a,2bの間に移動軸部3が介設された状態が保持される。すなわち、弾性バネ5以外の上記状態を保持するための固定部材等を有するものではなく、本実施形態の挟持具1をシンプルな構成で構築することができる。   The holding tool 1 of this embodiment is constructed | assembled by assembling using the said structure. Specifically, first, the spring end 21 of the elastic spring 5 is inserted and fixed in the spring hole 14 provided in each of the sandwiching piece outer surfaces 14 of the pair of sandwiching pieces 2a and 2b. Then, the substantially cylindrical moving shaft portion 3 is inserted between the pair of sandwiching pieces 2a and 2b. At this time, the distance between the pair of sandwiching pieces 2 a and 2 b is narrower than the shaft diameter of the moving shaft portion 3 (corresponding to the diameter of the disk-shaped member) by the elastic spring 5 described above. Therefore, it is necessary to insert it so as to widen the interval against the elastic force of the elastic spring 5. As a result, the movement shaft portion 3 is inserted between the one trough portion 12 of the contact surface 10 of the movement restricting portion 6, and the peripheral surface 16 of the movement shaft portion 3 and the contact surface 10 of the movement restricting portion 6 abut. It will be in the state. Here, by setting the moving shaft portion 3 to be positioned between the trough portions 12 on the side far from the sandwiching portion 7, the sandwiching portions 7 are brought into close proximity (the sandwiching position CP: FIG. 3A). reference). The urging position by the elastic spring 5 is located forward of the moving shaft 3 (left direction in FIG. 3), in other words, between the moving shaft 3 and the sandwiching portion 7. Thereby, as shown in FIG. 1 etc., the clamping tool 1 in the clamping position CP presenting a substantially triangular shape is generated by the pair of clamping pieces 2a, 2b and the moving shaft portion 3. Here, a part of the bulging portion 22 of the bent elastic spring 5 is accommodated in the gap 23 formed by separating the pair of disk-like members 17 of the moving shaft portion 3 from each other. Thereby, the state in which the moving shaft portion 3 is interposed between the pair of sandwiching pieces 2 a and 2 b is held by the elastic spring 5. That is, it does not have a fixing member or the like for holding the above state other than the elastic spring 5, and the holding tool 1 of the present embodiment can be constructed with a simple configuration.

次に、第一実施形態の挟持具1の使用方法、換言すれば、挟持位置CPから挟持解除位置DPに一対の挟持片2a,2bを変位させる際の挟持具1の動きについて詳述することとする。まず、挟持位置CP(図3(a)参照)にある挟持具1に対し、親指及び人差し指(図示しない)でそれぞれの把持部4を把持し、これを近接させる方向に力を加える。このとき、挟持具1の弾性バネ5によって挟持部7を近接させる方向に付勢するような弾性力が作用している。そのため、把持部同士4の近接を完了させるためには、弾性バネ5の付勢力に抗する程度の強い力を必要とする。   Next, how to use the holding tool 1 of the first embodiment, in other words, the movement of the holding tool 1 when displacing the pair of holding pieces 2a and 2b from the holding position CP to the holding release position DP will be described in detail. And First, with respect to the clamping tool 1 in the clamping position CP (see FIG. 3A), the gripping portions 4 are gripped by the thumb and forefinger (not shown), and a force is applied in a direction in which the gripping portions 4 are brought close to each other. At this time, an elastic force is applied so that the elastic spring 5 of the holding tool 1 urges the holding portion 7 in the direction in which the holding portion 7 approaches. Therefore, in order to complete the proximity of the gripping portions 4, a strong force that resists the biasing force of the elastic spring 5 is required.

係る動作(把持動作)において、移動軸部3は支点として作用する。同様に、挟持部7は作用点、把持部4は力点として作用することになる。そして、把持部4同士を近接させることにより、対向面9に設けられた移動規制部6の互いに対向する当接面10の間を移動軸部3が移動しようとする力が働く。具体的に示すと、上記動作によって、移動軸部3が前方向(挟持部側:図3における紙面左方向)に向かって押出される力が作用する。そのため、一方の谷部12に位置していた移動軸部3は、他方の谷部12に移動しようとする。しかしながら、二つの谷部12の間には、上方に突出した山部11が存在しているため、把持部4を近接させる力が弱いと、移動軸部3は当該山部11を越えることができない。すなわち、弾性バネ5による付勢位置は、移動軸部3の前側で変化することがなく、挟持部7同士を近接させる力が作用し、係る状態で把持を止めると、元の挟持位置CPの状態に復帰することになる。   In such an operation (gripping operation), the moving shaft portion 3 acts as a fulcrum. Similarly, the clamping part 7 acts as an action point, and the grip part 4 acts as a power point. And the force which the moving shaft part 3 tries to move between the contact surfaces 10 which the movement control part 6 provided in the opposing surface 9 mutually opposes works by making the holding parts 4 adjoin. Specifically, by the above-described operation, a force that pushes the moving shaft portion 3 toward the front direction (the sandwiching portion side: the left side in FIG. 3) acts. For this reason, the moving shaft portion 3 located in the one valley portion 12 tends to move to the other valley portion 12. However, since there is a peak 11 protruding upward between the two valleys 12, if the force for bringing the gripping part 4 close is weak, the moving shaft part 3 may exceed the peak 11. Can not. That is, the urging position by the elastic spring 5 does not change on the front side of the moving shaft part 3, and a force that brings the holding parts 7 close to each other acts. It will return to the state.

一方、山部11に到達した移動軸部3(図3(b)参照)に対し、さらに把持部4を近接させるように力を加えることにより、移動軸部3は当接面10に沿って山部11の頂点を越え、他方の谷部12に移ることになる。その結果、バネ端部21による付勢位置が移動軸部3の後方向(把持部4側)になる。その結果、把持部4同士を近接させる、換言すれば、挟持部7同士を互いに離間させる方向に弾性力が作用し、付勢されることになる。これにより、挟持具1が挟持解除位置DPに付勢される(図3(c)参照)。   On the other hand, by applying a force so that the gripping part 4 is further brought closer to the moving shaft part 3 (see FIG. 3B) that has reached the peak part 11, the moving shaft part 3 moves along the contact surface 10. It will move to the other valley 12 beyond the peak of the mountain 11. As a result, the urging position by the spring end portion 21 is in the rearward direction of the moving shaft portion 3 (on the grip portion 4 side). As a result, the elastic force acts in the direction in which the gripping portions 4 are brought close to each other, in other words, the gripping portions 7 are separated from each other, and is biased. Thereby, the clamping tool 1 is urged | biased to the clamping cancellation | release position DP (refer FIG.3 (c)).

これにより、上記動作によって、移動軸部3が移動規制部6に沿って移動し(図3における紙面右方向から左方向への移動)、挟持具1の弾性バネ5による付勢位置が移動軸部3の前後で変化することになる。その結果、挟持片2a,2bを挟持位置CP及び挟持解除位置DPのいずれかにそれぞれ弾性力を利用して付勢することができる。特に、当接面10に形成された山部11及び一対の谷部12によって、規定以上の力が加わるまでは通常の洗濯ばさみと同様の使用をすることができ、さらに、規定以上の力が加わるとそれまでの付勢方向が逆転し、挟持部7の近接または離間状態を保持することができる。   Thereby, the movement shaft part 3 moves along the movement restriction part 6 by the above operation (movement from the right side to the left side in FIG. 3), and the urging position of the holding tool 1 by the elastic spring 5 is the movement axis. It will change before and after part 3. As a result, the sandwiching pieces 2a and 2b can be urged to either the sandwiching position CP or the sandwiching release position DP using elastic force. In particular, the peak portion 11 and the pair of trough portions 12 formed on the abutting surface 10 can be used in the same manner as normal clothespins until a force exceeding a specified level is applied. When a force is applied, the urging direction up to that time is reversed, and the proximity or separation state of the clamping part 7 can be maintained.

なお、挟持解除位置DP(図3(c))から挟持位置CP(図3(a))への変位は、上記と逆の操作を行うことにより、移動軸部3を図3における紙面左方向から右方向へ移動させることにより可能となり、同様の作用効果を奏することができる。そのため、詳細な説明については省略する。   Note that the displacement from the pinching release position DP (FIG. 3C) to the pinching position CP (FIG. 3A) is carried out by performing the reverse operation to move the moving shaft portion 3 leftward in FIG. It becomes possible by moving to the right, and the same effect can be obtained. Therefore, detailed description is omitted.

指先の力の弱い高齢者や片手での作業が困難な人々にとっても、挟持具1を用いた挟持動作及び挟持解除動作を、安定かつ楽に行うことができる。加えて、本実施形態の場合、挟持具1の挟持片2a,2bをそれぞれ移動規制部6(またはバネ孔14)を中心として左右対称形で形成している。そのため、上記説明では、挟持片2a,2bの左端を挟持部7及び右端を把持部4として説明したが、同様に左端が把持部4及び右端が挟持部7として機能することもできる。そのため、従来の洗濯ばさみ等のように挟持方向が一方向に限定されるものではない。そのため、使用者が本実施形態の挟持具1を把持し、そのまま挟持方向に合わせる持ち替え動作を行わずに、そのまま挟持動作や挟持解除動作を行うことが可能となる。そのため、片手の不自由な人々等にとってさらに使用感が良好なものとなる。加えて、本実施形態の挟持具1によれば、移動軸部3に設けられたガイド機能を奏するフランジ20に係る構成によって、移動軸部3の挟持片2a,2bの長手方向に沿った移動が安定したものとなる。   Even for elderly people with weak fingertips and people who are difficult to work with one hand, the clamping operation and the clamping release operation using the clamping tool 1 can be performed stably and easily. In addition, in the case of this embodiment, the clamping pieces 2a and 2b of the clamping tool 1 are formed symmetrically about the movement restricting portion 6 (or the spring hole 14). Therefore, in the above description, the left ends of the sandwiching pieces 2a and 2b have been described as the sandwiching portion 7 and the right end as the gripping portion 4, but similarly, the left end can function as the gripping portion 4 and the right end as the sandwiching portion 7. Therefore, the pinching direction is not limited to one direction like conventional clothespins. Therefore, the user can hold the holding tool 1 of this embodiment and perform the holding operation and the holding release operation as it is without performing the holding operation to match the holding direction as it is. Therefore, the feeling of use is further improved for people with disabilities in one hand. In addition, according to the holding tool 1 of the present embodiment, the movement of the holding pieces 2a and 2b of the moving shaft portion 3 along the longitudinal direction is achieved by the configuration related to the flange 20 having the guide function provided on the moving shaft portion 3. Becomes stable.

さらに、複数に曲折し、中央部に膨出部22を有する弾性バネ5を用い、かつ移動軸部3に円盤状部材17及び連結部19から構成されるものを用いることにより、挟持位置CPまたは挟持解除位置DPのいずれか一方に挟持具1があるときに、弾性バネ5の一部を空隙23に収容することができる。そのため、上記の左右対称形の挟持片2a,2bを採用した場合、従来使用されているリング状バネでは、当該リング状バネの一部が挟持部の間の空間に突出する可能性があり、十分な挟持ができないことが想定される。したがって、本実施形態の挟持具1において示した弾性バネ5(図2参照)を使用することによって、上記不具合を解消することができる。   Further, by using the elastic spring 5 having a plurality of bent portions and having a bulging portion 22 at the center and using the moving shaft portion 3 composed of the disk-like member 17 and the connecting portion 19, the clamping position CP or A part of the elastic spring 5 can be accommodated in the gap 23 when the clamping tool 1 is in one of the clamping release positions DP. Therefore, when the above-described left and right symmetrical sandwiching pieces 2a and 2b are employed, in a conventionally used ring-shaped spring, a part of the ring-shaped spring may protrude into the space between the sandwiching portions. It is assumed that sufficient clamping cannot be performed. Therefore, the said malfunction can be eliminated by using the elastic spring 5 (refer FIG. 2) shown in the clamping tool 1 of this embodiment.

次に、本発明の第二実施形態である挟持具30について、図4及び図5に基づいて説明する。ここで、図4は第二実施形態の挟持具30の構成を示す分解斜視図であり、図5は(a)移動禁止位置、(b)移動禁止位置における挟持動作、(c)移動解除位置、及び(d)移動解除位置における挟持動作のそれぞれの挟持具30の状態を示す説明図である。なお、第二実施形態の挟持具30において、第一実施形態の挟持具1と略同一の構成については、説明を簡略化するため、同一番号を付し、詳細な説明を省略するものとする。   Next, the clamping tool 30 which is 2nd embodiment of this invention is demonstrated based on FIG.4 and FIG.5. Here, FIG. 4 is an exploded perspective view showing the configuration of the clamping tool 30 of the second embodiment, and FIG. 5 is (a) a movement prohibited position, (b) a clamping operation at the movement prohibited position, and (c) a movement release position. (D) It is explanatory drawing which shows the state of each clamping tool 30 of the clamping operation | movement in a movement cancellation | release position. In addition, in the clamping tool 30 of 2nd embodiment, about the structure substantially the same as the clamping tool 1 of 1st embodiment, in order to simplify description, the same number shall be attached | subjected and detailed description shall be abbreviate | omitted. .

第二実施形態の挟持具30は、図4及び図5に示すように、一対の挟持片31a,31bと、該挟持片31a,31bの間に挟込んで介設した移動軸部32と、移動軸部32を介設した状態でそれぞれの挟持片31a,31bを所定方向に弾性力を利用して付勢する弾性バネ5とを主に具備して構成されている。   As shown in FIGS. 4 and 5, the sandwiching tool 30 of the second embodiment includes a pair of sandwiching pieces 31 a and 31 b, and a moving shaft portion 32 interposed between the sandwiching pieces 31 a and 31 b. An elastic spring 5 that mainly urges each of the clamping pieces 31a and 31b in a predetermined direction by using an elastic force with the moving shaft portion 32 interposed therebetween is configured.

さらに詳細に説明すると、移動軸部32は、移動規制部6の当接面10と少なくとも一部た当接する周面33を四面備える断面樽形状の連結部材34と、連結部材34の長さだけ離間させて接続された一対の楕円形状を呈するフランジ35とを具備して構築されている。ここで、楕円形状のフランジ35のフランジ周面36が後述する摺動溝部37のフランジ受孔38と略一致する形状を有し、さらにフランジ35のフランジ裏面39が摺動溝部37の溝面38に当接し、係る当接状態を維持しながら挟持片31a,31bの長手方向に沿って移動軸部32が摺動することとなる。   More specifically, the moving shaft portion 32 has a barrel-shaped connecting member 34 having four circumferential surfaces 33 that abut at least a part of the contact surface 10 of the movement restricting portion 6, and the length of the connecting member 34. And a pair of ellipse-shaped flanges 35 connected to be separated from each other. Here, the flange circumferential surface 36 of the elliptical flange 35 has a shape that substantially coincides with a flange receiving hole 38 of the sliding groove portion 37 described later, and the flange back surface 39 of the flange 35 is a groove surface 38 of the sliding groove portion 37. The moving shaft portion 32 slides along the longitudinal direction of the sandwiching pieces 31a and 31b while maintaining the contact state.

一方、一対の挟持片31a,31bは、それぞれの挟持片壁40(当接面10に直交する面に相当)には、所定の深さ(前述のフランジ35のフランジ厚に略一致)に削設された摺動溝部37が形成されている。ここで、摺動溝部37は、上記のフランジ35のフランジ周面36の一部と略一致する形状を有する一対のフランジ受孔41が挟持片31a,31bの左右にそれぞれ一対が設けられ、その間を連結し、フランジ周面36と当接可能な連結接面42が形成されている。なお、挟持片31a,31bのそれぞれの反対側に位置する挟持片壁40(図5における紙面裏面に相当)にも同様に係る摺動溝部37が形成されている。なお、摺動溝部37の横幅は、当接面10を有する移動規制部6の規制範囲に略一致している。   On the other hand, the pair of sandwiching pieces 31a and 31b has a predetermined depth (substantially coincident with the flange thickness of the aforementioned flange 35) in each sandwiching piece wall 40 (corresponding to a surface orthogonal to the contact surface 10). The provided sliding groove part 37 is formed. Here, the sliding groove portion 37 is provided with a pair of flange receiving holes 41 having a shape substantially coincident with a part of the flange circumferential surface 36 of the flange 35, and a pair of flange receiving holes 41a and 31b, respectively. And a connecting contact surface 42 that can contact the flange peripheral surface 36 is formed. In addition, the sliding groove part 37 which concerns similarly is formed also in the clamping piece wall 40 (equivalent to the paper back surface in FIG. 5) located in the other side of each clamping piece 31a, 31b. Note that the lateral width of the sliding groove portion 37 substantially matches the restriction range of the movement restricting portion 6 having the contact surface 10.

次に第二実施形態の挟持具30の使用例について、主に図5に基づいて説明する。ここで、図5(a)は楕円形状のフランジ35を縦方向に配し、移動軸部32の移動を禁止する位置に設定したものである。係る状態においてフランジ35のフランジ周面36の少なくとも一部が挟持片31a,31b側のフランジ38の形状と略一致した状態(嵌合状態)が生成されている。これにより、移動軸部32の移動(紙面右方から左方への移動)が禁止されることとなる。そのため、互いに離間した把持部41同士を近接させるように弾性バネ5の弾性力に抗する力を加えた場合、図5(b)に示すように移動軸部32の楕円形状のフランジ35のフランジ周面36とフランジ受孔38の孔面38aとの間で摺動が生じるだけであり、全体として移動軸部32のフランジ35を軸とした一対の挟持片31a,31bによる開動作(挟持部42が離間した状態)が生じることとなる。   Next, the usage example of the clamping tool 30 of 2nd embodiment is mainly demonstrated based on FIG. Here, FIG. 5A shows an elliptical flange 35 arranged in the vertical direction and set at a position where the movement of the moving shaft portion 32 is prohibited. In such a state, a state (fitted state) is generated in which at least a part of the flange circumferential surface 36 of the flange 35 substantially matches the shape of the flange 38 on the clamping pieces 31a and 31b side. As a result, the movement of the movement shaft portion 32 (movement from the right side to the left side of the drawing) is prohibited. Therefore, when a force against the elastic force of the elastic spring 5 is applied so that the gripping portions 41 that are separated from each other are brought close to each other, the flange of the elliptical flange 35 of the moving shaft portion 32 as shown in FIG. Only sliding occurs between the peripheral surface 36 and the hole surface 38a of the flange receiving hole 38, and as a whole, an opening operation (a clamping portion) by the pair of clamping pieces 31a and 31b with the flange 35 of the moving shaft portion 32 as an axis. 42 is separated).

一方、移動軸部32のフランジ45を横方向に配した場合(図5(c)参照)、係る状態ではフランジ周面36及びフランジ受孔38の間の嵌合状態が解除された状態となる。その結果、当該状態で上記と同様に互いの把持部41同士を近接させるように力を加えることにより、断面樽形状の連結部材34の周面33が移動規制部6の当接面10に沿って摺動することとなる。このとき、フランジ周面36は摺動溝部37の連結接面42に当接しながら移動することとなる。それにより、最終的に図5(d)の状態に変移する。すなわち、楕円形状のフランジ36を90度回転させるだけで、フランジ受孔38との嵌合状態を変化させることができ、これにより移動軸部32の移動の禁止及び解除を任意に設定することができる。そのため、使用状況に応じた使用態様をとることができる。   On the other hand, when the flange 45 of the moving shaft portion 32 is disposed in the lateral direction (see FIG. 5C), in this state, the fitting state between the flange peripheral surface 36 and the flange receiving hole 38 is released. . As a result, the peripheral surface 33 of the connecting member 34 having the barrel-shaped cross section is along the contact surface 10 of the movement restricting portion 6 by applying a force so that the gripping portions 41 are brought close to each other in the same manner as described above. Will slide. At this time, the flange peripheral surface 36 moves while coming into contact with the connecting contact surface 42 of the sliding groove portion 37. Thereby, the state finally changes to the state of FIG. That is, it is possible to change the fitting state with the flange receiving hole 38 only by rotating the elliptical flange 36 by 90 degrees, and thereby, the prohibition and release of the movement of the moving shaft portion 32 can be arbitrarily set. it can. Therefore, it is possible to take a usage mode according to the usage situation.
