Description

本発明は、被固定部材に取り付けられて固定される固定具に関するものである。 The present invention relates to a fixative that is attached and fixed to a member to be fixed.

従来、例えば、薄い金属板や薄葉紙等は、ドラムや芯材(以下、「ドラム等」と記す。)に巻き付けられ、このドラム等は、円柱状の棒材に通されることで、自在に回転し、薄葉紙や薄い金属板等が引っ張り出されるところ、ドラム等が棒材から抜けることを防ぐ必要がある。そこで、棒材に取り付けられることで、ドラム等が棒材から抜けることを防ぐ部材として、例えば、下記特許文献1に記載された固定治具がある(以下、「文献公知1発明」と記す。)。 Conventionally, for example, a thin metal plate, tissue paper, or the like is wound around a drum or a core material (hereinafter referred to as "drum or the like"), and the drum or the like is freely passed through a cylindrical rod material. It is necessary to prevent the drum or the like from coming off the bar when it rotates and the thin paper or the thin metal plate is pulled out. Therefore, as a member for preventing the drum or the like from coming off the bar by being attached to the bar, for example, there is a fixing jig described in Patent Document 1 below (hereinafter, referred to as "literature known 1 invention". ).

文献公知1発明は、筒状本体に、棒材が通される中心孔が形成され、係止レバーが操作されることで、この係止レバーの先端が、中心孔の内側に突出し、棒材に係止する。係止レバーは、ピンを介して筒状本体に連結され、ピンを軸として回転する。係止レバーの先端である係止面は、ピンの回転軸に対して偏心しているため、係止レバーが回転することで、係止面が中心孔の内側に突出する。係止レバーにコイルバネが取り付けられている場合、係止レバーは、コイルバネの弾性力で操作される。 In the first invention known in the literature, a central hole through which a bar is passed is formed in a cylindrical body, and when the locking lever is operated, the tip of the locking lever protrudes inside the center hole and the bar is used. Lock to. The locking lever is connected to the tubular body via a pin and rotates about the pin. Since the locking surface at the tip of the locking lever is eccentric with respect to the rotation axis of the pin, the locking surface protrudes inside the center hole when the locking lever rotates. When a coil spring is attached to the locking lever, the locking lever is operated by the elastic force of the coil spring.

しかし、文献公知1発明の係止面は、ピンを中心とした円周に沿った湾曲面であり、一方で、棒材は、円柱状であることから、両者の接触箇所は、ほぼ点であるため、この一点のみにおいて係止された両者は、ズレやすい。また、点において係止された状態で両者がズレると、係止面と棒材との摩擦力が、接触箇所である一点に集中し、棒材に傷が付く場合があるし、係止面が摩耗しやすい。さらに、操作レバーにコイルバネが取り付けられている場合、弾性力に抗して操作する必要があるため、コイルバネのバネ定数が大きい程、操作し辛くなる。 However, the locking surface of the first invention known in the literature is a curved surface along the circumference centered on the pin, while the rod material is columnar, so that the contact points between the two are substantially points. Therefore, the two locked at only this one point are likely to be misaligned. Further, if the two are displaced from each other in a state of being locked at a point, the frictional force between the locking surface and the bar material is concentrated on one point at the contact point, and the bar material may be scratched, and the locking surface may be damaged. Is easy to wear. Further, when the coil spring is attached to the operating lever, it is necessary to operate against the elastic force, so that the larger the spring constant of the coil spring, the harder it is to operate.

本発明は、上記の実情に鑑みて提案されたものである。すなわち、取り付けられる対象である被固定部材から外れること、被固定部材に傷が付くこと、摩耗するのを抑止すること、及び、操作のし易さを実現した固定具の提供を目的とする。 The present invention has been proposed in view of the above circumstances. That is, it is an object of the present invention to provide a fixture that realizes ease of operation, that is, it is prevented from being detached from the fixed member to be attached, the fixed member is scratched, and is not worn.

上記目的を達成するために、本発明に係る固定具は、棒状の被固定部材が通される把持孔が形成された本体部と、前記把持孔と直交する方向を回転軸として回転する軸部材と、前記軸部材を回転させる操作部と、を有し、前記本体部が、前記把持孔と直交すると共に前記軸部材が通された支持孔と、前記支持孔と直交すると共に前記操作部が通された操作孔と、を有し、前記操作部が、前記軸部材と直交して連結された連結部と、前記連結部から前記操作孔に沿って伸びた操作端部と、前記連結部から前記操作孔に沿って前記操作端部と反対側に伸びた弾性作用部と、前記弾性作用部に取り付けられた弾性部材と、を有し、前記軸部材が、前記本体部に支持された被支持部と、前記被支持部と連接されると共に前記回転軸に対して偏心し、前記把持孔の内周面において露出した偏心部と、を有し、前記偏心部に、前記被固定部材の側面と周方向に渡って接触する弧状接触面が形成され、前記軸部材が前記弾性部材の弾性力によって回転することで、前記弧状接触面が、前記把持孔の内周面において前記被固定部材を押さえ付ける、ことを特徴とする。 In order to achieve the above object, the fixture according to the present invention has a main body portion in which a grip hole through which a rod-shaped fixed member is passed is formed, and a shaft member that rotates with a direction orthogonal to the grip hole as a rotation axis. And an operation unit for rotating the shaft member, the main body portion is orthogonal to the grip hole and the support hole through which the shaft member is passed, and the operation unit is orthogonal to the support hole. A connecting portion having an operating hole through which the operating portion is connected orthogonally to the shaft member, an operating end portion extending from the connecting portion along the operating hole, and the connecting portion. It has an elastic action portion extending from the operation hole to the opposite side of the operation end portion and an elastic member attached to the elastic action portion, and the shaft member is supported by the main body portion. It has a supported portion, an eccentric portion that is connected to the supported portion and is eccentric with respect to the rotation axis, and is exposed on the inner peripheral surface of the gripping hole. The eccentric portion has the fixed member. An arc-shaped contact surface that comes into contact with the side surface in the circumferential direction is formed, and the shaft member is rotated by the elastic force of the elastic member, so that the arc-shaped contact surface is fixed on the inner peripheral surface of the gripping hole. It is characterized by pressing down a member.

本発明に係る固定具は、前記操作孔が、前記本体部のうち、前記把持孔が形成された面と同一面に形成された溝であって、かつ、前記本体部のうち、前記操作端部側が開放され、前記操作部が、前記本体部の外側に突出した前記操作端部に形成されて前記本体部と対面した補助操作部を有する、ことを特徴とする。 In the fixture according to the present invention, the operation hole is a groove formed on the same surface as the surface on which the gripping hole is formed in the main body portion, and the operation end of the main body portion. The operation portion is open, and the operation portion has an auxiliary operation portion formed on the operation end portion protruding to the outside of the main body portion and facing the main body portion.

本発明に係る固定具は、前記弾性作用部が、圧縮した前記弾性部材が復元する方向に向けて伸びている、ことを特徴とする。 The fixture according to the present invention is characterized in that the elastic acting portion extends in a direction in which the compressed elastic member is restored.

本発明に係る固定具は、棒状の被固定部材が通される把持孔が形成された本体部と、把持孔と直交する方向を回転軸として回転する軸部材と、軸部材を回転させる操作部とを有し、本体部が、把持孔と直交すると共に軸部材が通された支持孔と、支持孔と直交すると共に操作部が通された操作孔とを有し、操作部が、軸部材と直交して連結された連結部と、連結部から操作孔に沿って伸びた操作端部と、連結部から操作孔に沿って操作端部と反対側に伸びた弾性作用部と、弾性作用部に取り付けられた弾性部材とを有し、軸部材が、本体部に支持された被支持部と、被支持部と連接されると共に回転軸に対して偏心し、把持孔の内周面において露出した偏心部とを有し、偏心部に、被固定部材の側面と周方向に渡って接触する弧状接触面が形成され、軸部材が弾性部材の弾性力によって回転することで、弧状接触面が、把持孔の内周面において被固定部材を押さえ付けるものである。この構成により、被固定部材と偏心部との接触箇所が面状となるため、固定具が被固定部材から外れ難い。そうであれば、両者がズレることで生じる被固定部材の損傷や弧状接触面の摩耗も抑止される。さらに、このような部材等を要しない分、部品点数が少なくて済む。操作部は、連結部に対して操作端部と反対側に弾性部材を有しているため、回転中心となる連結部から、操作による外力が作用する操作端部までの長さ、及び、弾性力が作用する弾性作用部までの長さ相当分、小さい力でモーメントが生じる。したがって、操作がし易い。 The fixture according to the present invention has a main body portion in which a grip hole through which a rod-shaped fixed member is passed is formed, a shaft member that rotates about a direction orthogonal to the grip hole as a rotation axis, and an operation unit that rotates the shaft member. The main body has a support hole orthogonal to the grip hole and through which the shaft member is passed, and an operation hole orthogonal to the support hole and through which the operation portion is passed, and the operation portion is the shaft member. An elastic action part extending from the connecting part along the operation hole, an elastic action part extending from the connection part along the operation hole to the opposite side to the operation end part, and an elastic action part. It has an elastic member attached to the portion, and the shaft member is connected to the supported portion supported by the main body portion and eccentric with respect to the rotating shaft, and is eccentric to the rotating shaft on the inner peripheral surface of the grip hole. It has an exposed eccentric part, and an arc-shaped contact surface that comes into contact with the side surface of the fixed member in the circumferential direction is formed in the eccentric part, and the shaft member is rotated by the elastic force of the elastic member to form an arc-shaped contact surface. However, the member to be fixed is pressed on the inner peripheral surface of the gripping hole. With this configuration, the contact point between the fixed member and the eccentric portion becomes planar, so that the fixture does not easily come off from the fixed member. If this is the case, damage to the fixed member and wear of the arcuate contact surface caused by the displacement between the two are also suppressed. Further, since such a member is not required, the number of parts can be reduced. Since the operating portion has an elastic member on the side opposite to the operating end with respect to the connecting portion, the length from the connecting portion that is the center of rotation to the operating end on which the external force due to the operation acts, and the elasticity. A moment is generated with a small force corresponding to the length to the elastic action part on which the force acts. Therefore, it is easy to operate.

本発明に係る固定具は、操作孔が、本体部のうち、把持孔が形成された面と同一面に形成された溝であって、かつ、本体部のうち、操作端部側が開放され、操作部が、本体部の外側に突出した操作端部に形成されて本体部と対面した補助操作部を有している。この構成により、操作者が操作部を操作する際、操作部が操作孔から突き出した単なる棒状であった場合と比較して、操作者は親指等を補助操作部に当て易くなるため、操作がし易い。 In the fixture according to the present invention, the operation hole is a groove formed on the same surface as the surface on which the grip hole is formed in the main body portion, and the operation end portion side of the main body portion is opened. The operation unit has an auxiliary operation unit that is formed at an operation end portion that protrudes to the outside of the main body unit and faces the main body unit. With this configuration, when the operator operates the operation unit, the operator can easily put his thumb or the like on the auxiliary operation unit as compared with the case where the operation unit is a simple rod protruding from the operation hole, so that the operation can be performed. Easy to do.

本発明に係る固定具は、弾性作用部が、圧縮した弾性部材が復元する方向に向けて伸びている。すなわち、弾性作用部は、連結部から操作端部と反対側に向けて、かつ、弾性力が復元する方向に向けて伸びている。この構成により、操作孔において、弾性作用部の周囲に広い隙間が形成されるため、この隙間に大きな弾性部材を取り付けることができ、大きな弾性力をもって軸部材が回転する。したがって、堅固に被固定部材を押さえ付けることができる。また、大きな弾性部材が取り付けられた場合であっても、小さい力でモーメントを生じさせることができる。 In the fixture according to the present invention, the elastic acting portion extends in the direction in which the compressed elastic member is restored. That is, the elastic action portion extends from the connecting portion toward the side opposite to the operation end portion and in the direction in which the elastic force is restored. With this configuration, a wide gap is formed around the elastic acting portion in the operation hole, so that a large elastic member can be attached to this gap, and the shaft member rotates with a large elastic force. Therefore, the fixed member can be firmly pressed down. Further, even when a large elastic member is attached, a moment can be generated with a small force.

以下に、本発明の実施形態に係る固定具を図面に基づいて説明する。図1及び2は、本発明の第一参考例に係る固定具2が示されている。固定具2は、操作部18が本発明の実施形態と異なるが、それ以外の構成は、後述する本発明の実施形態に係る固定具302(図11及び12参照。)と同じである。したがって、はじめに、固定具2に基づいて本発明の実施形態の全容を説明し、固定具302に基づいて操作部318を説明する。なお、以下の説明では、図1に示されているとおり、固定具2が固定される被固定部材1の長手方向を、前方(Forward)又は後方(Backward)とし、被固定部材1と直交する方向を、下方(Up)、下方(Down)、右方(Right Side)及び左方(Left Side)とする。 Hereinafter, the fixture according to the embodiment of the present invention will be described with reference to the drawings. 1 and 2 show the fixture 2 according to the first reference example of the present invention. The fixture 2 has an operation unit 18 different from that of the embodiment of the present invention, but other configurations are the same as those of the fixture 302 (see FIGS. 11 and 12) according to the embodiment of the present invention described later. Therefore, first, the whole of the embodiment of the present invention will be described based on the fixture 2, and the operation unit 318 will be described based on the fixture 302. In the following description, as shown in FIG. 1, the longitudinal direction of the fixed member 1 to which the fixture 2 is fixed is defined as front (Forward) or rear (Backward), and is orthogonal to the fixed member 1. The directions are downward (Up), downward (Down), right (Right Side) and left (Left Side).

図1に示されているとおり、固定具2は、円柱の棒状である被固定部材1に取り付けられて固定されるものであり、被固定部材1に通されたドラム等(図示省略。)が、被固定部材1から抜けることを防ぐものである。固定具2は、被固定部材1に取り付けられる本体部3と、この本体部3に支持されて回転する軸部材8と、この軸部材8に連結されて軸部材8を回転させる操作部18とを有している。 As shown in FIG. 1, the fixture 2 is attached and fixed to a cylindrical rod-shaped fixed member 1, and a drum or the like (not shown) passed through the fixed member 1 is attached and fixed. , It is intended to prevent the member to be fixed from coming off. The fixture 2 includes a main body portion 3 attached to the fixed member 1, a shaft member 8 that is supported by the main body portion 3 and rotates, and an operation unit 18 that is connected to the shaft member 8 and rotates the shaft member 8. have.

図1及び2に示されているとおり、本体部3は、ほぼ直方体であり、本体部3の角は、適宜C面取り加工が施されている。本体部3は、被固定部材1が通される把持孔4と、軸部材8が通される支持孔5と、操作部18が通される操作孔6とが形成されている。把持孔4は、被固定部材1の側面形状に倣った円筒形であり、本体部3における前後外面の中心を前後方向に貫通している。支持孔5は、軸部材8に倣った円筒形であり、本体部3における左右外側面の上側寄りを左右方向に貫通し、把持孔4と直交すると共に把持孔4に通じている。すなわち、把持孔4と支持孔5とが重なることによって、各孔4,5の一部が開口し、開口部7が形成されている。開口部7は、把持孔4を形成する内周面のうち、上部分の一部を開口すると共に、支持孔5を形成する内周面のうち、下部分の一部を開口し、各孔4,5の境界を構成している。操作孔6は、前後方向に長い長孔であり、本体部3のうち、把持孔4を軸とした上外側面の右側寄りを、支持孔5に至って貫通し、支持孔5と直交すると共に支持孔5に通じている。 As shown in FIGS. 1 and 2, the main body portion 3 is a substantially rectangular parallelepiped, and the corners of the main body portion 3 are appropriately chamfered with C. The main body portion 3 is formed with a grip hole 4 through which the fixed member 1 is passed, a support hole 5 through which the shaft member 8 is passed, and an operation hole 6 through which the operation portion 18 is passed. The gripping hole 4 has a cylindrical shape that follows the side surface shape of the fixed member 1, and penetrates the center of the front-rear outer surface of the main body 3 in the front-rear direction. The support hole 5 has a cylindrical shape that imitates the shaft member 8, penetrates the upper side of the left and right outer surfaces of the main body 3 in the left-right direction, is orthogonal to the grip hole 4, and is connected to the grip hole 4. That is, by overlapping the gripping hole 4 and the support hole 5, a part of each of the holes 4 and 5 is opened, and the opening 7 is formed. The opening 7 opens a part of the upper part of the inner peripheral surface forming the grip hole 4, and also opens a part of the lower part of the inner peripheral surface forming the support hole 5, and each hole. It constitutes the boundaries of 4 and 5. The operation hole 6 is a long hole long in the front-rear direction, penetrates the right side of the upper and outer surfaces of the main body 3 with the grip hole 4 as an axis, reaches the support hole 5, and is orthogonal to the support hole 5. It leads to the support hole 5.

軸部材8は、断面が円形の棒状であり、中央に偏心部10を有し、この偏心部10の両端に被支持部9が連接されている。偏心部10と被支持部9とは、直線上に連接されている。偏心部10の一部は、外周面が一周に渡って凹弧状に形成されている。右側の被支持部9は、操作部18と連結される被支持部側連結部15を有している。被支持部側連結部15は、被支持部9の側面に形成された雌ネジ穴である。軸部材8は、本体部3の支持孔5に通され、被支持部9が本体部3に支持され、偏心部10が開口部7に配置される。偏心部10は、把持孔4の内周面において露出する。軸部材8は、支持孔5において、把持孔4と直交する方向である左右方向を回転軸16として回転する。 The shaft member 8 has a rod-shaped cross section with a circular cross section, has an eccentric portion 10 in the center, and the supported portions 9 are connected to both ends of the eccentric portion 10. The eccentric portion 10 and the supported portion 9 are connected to each other on a straight line. A part of the eccentric portion 10 has an outer peripheral surface formed in a concave arc shape over the entire circumference. The supported portion 9 on the right side has a supported portion side connecting portion 15 that is connected to the operating portion 18. The supported portion side connecting portion 15 is a female screw hole formed on the side surface of the supported portion 9. The shaft member 8 is passed through the support hole 5 of the main body portion 3, the supported portion 9 is supported by the main body portion 3, and the eccentric portion 10 is arranged in the opening portion 7. The eccentric portion 10 is exposed on the inner peripheral surface of the grip hole 4. The shaft member 8 rotates in the support hole 5 with the left-right direction, which is a direction orthogonal to the grip hole 4, as the rotation axis 16.

操作部18は、棒状であり、被支持部9と連結される操作部側連結部19を有している。操作部側連結部19は、操作部18の先端部に形成された雄ネジである。操作部18は、本体部3の操作孔6に通され、操作孔6の中で、軸部材8における被支持部9の側面に連結される。すなわち、操作部18の操作部側連結部19と、被支持部9の被支持部側連結部15とが、ネジ構造によって連結される。操作部18は、本体部3の外側に突出し、操作孔6の範囲において、本体部3における把持孔4の軸方向である前後方向に動く。したがって、操作部18が傾くことに連動して、軸部材8が回転する。 The operation unit 18 has a rod shape and has an operation unit side connecting portion 19 connected to the supported portion 9. The operation unit side connecting unit 19 is a male screw formed at the tip end portion of the operation unit 18. The operation portion 18 is passed through the operation hole 6 of the main body portion 3 and is connected to the side surface of the supported portion 9 in the shaft member 8 in the operation hole 6. That is, the operation portion side connecting portion 19 of the operation portion 18 and the supported portion side connecting portion 15 of the supported portion 9 are connected by a screw structure. The operation unit 18 projects to the outside of the main body 3 and moves in the front-rear direction, which is the axial direction of the grip hole 4 in the main body 3, within the range of the operation hole 6. Therefore, the shaft member 8 rotates in conjunction with the tilting of the operation unit 18.

ここで、軸部材8を図面に基づいて詳説する。図3ないし5は、固定具2、及び、本発明の実施形態に係る固定具302(図11及び12参照。)に用いられる軸部材8の外観及び断面が示されている。図3は、軸部材8の断面が示され、図4は、図3における矢印IVから視した外観であり、図5は、図3における矢印Vから視した外観である。 Here, the shaft member 8 will be described in detail with reference to the drawings. 3 to 5 show the appearance and cross section of the fixing tool 2 and the shaft member 8 used in the fixing tool 302 (see FIGS. 11 and 12) according to the embodiment of the present invention. 3 shows a cross section of the shaft member 8, FIG. 4 is an appearance seen from arrow IV in FIG. 3, and FIG. 5 is an appearance seen from arrow V in FIG.

図3ないし5に示されているとおり、軸部材8の回転軸16は、被支持部9の中心を通っている。偏心部10は、被支持部9と連接された基部11と、この基部11に連接されて基部11同士の間に配置された接触部12とから構成されている。基部11と接触部12とは、それぞれの中心を通る偏心軸17上に形成されている。偏心軸17は、回転軸16に対して偏心し、かつ、偏心部10は、被支持部9の外周面以内に形成されている。詳説すれば、偏心部10のうち、最も大きな円周である基部11の円周は、被支持部9の円周よりも小さく、かつ、回転軸16の軸方向から視した際の被支持部9の投影である投影円周P上に揃うか、投影円周Pよりも内側である。すなわち、偏心部10が回転軸16に対して偏心していることから、基部11が、投影円周Pから張り出す場合、基部11の外面のうち、投影円周Pから張り出した部分は、適宜研削されて投影円周Pに揃えられる(連接面14)。したがって、基部11は、偏心軸17を中心とすれば、真円ではなく、また、基部11の外面は、投影円周Pから張り出さない。 As shown in FIGS. 3 to 5, the rotating shaft 16 of the shaft member 8 passes through the center of the supported portion 9. The eccentric portion 10 is composed of a base portion 11 connected to the supported portion 9 and a contact portion 12 connected to the base portion 11 and arranged between the base portions 11. The base portion 11 and the contact portion 12 are formed on an eccentric axis 17 passing through the center of each. The eccentric shaft 17 is eccentric with respect to the rotating shaft 16, and the eccentric portion 10 is formed within the outer peripheral surface of the supported portion 9. More specifically, among the eccentric portions 10, the circumference of the base 11 which is the largest circumference is smaller than the circumference of the supported portion 9, and the supported portion when viewed from the axial direction of the rotating shaft 16. It is aligned on the projection circumference P, which is the projection of 9, or is inside the projection circumference P. That is, since the eccentric portion 10 is eccentric with respect to the rotation axis 16, when the base portion 11 projects from the projection circumference P, the portion of the outer surface of the base portion 11 that protrudes from the projection circumference P is appropriately ground. It is aligned with the projected circumference P (connecting surface 14). Therefore, the base 11 is not a perfect circle if the eccentric axis 17 is centered, and the outer surface of the base 11 does not project from the projection circumference P.

接触部12は、両端から中央に向かうにしたがって、徐々に直径が小さくなり、接触部12の外周面は、一周に渡って凹弧状に形成された弧状接触面13を有している。弧状接触面13は、被固定部材1の側面形状に倣った曲面である。弧状接触面13は、被支持部9の外周面よりも内側に形成されている。すなわち、弧状接触面13は、投影円周Pよりも内側に形成されている。 The diameter of the contact portion 12 gradually decreases from both ends toward the center, and the outer peripheral surface of the contact portion 12 has an arc-shaped contact surface 13 formed in a concave arc shape over one circumference. The arc-shaped contact surface 13 is a curved surface that follows the side surface shape of the fixed member 1. The arc-shaped contact surface 13 is formed inside the outer peripheral surface of the supported portion 9. That is, the arc-shaped contact surface 13 is formed inside the projected circumference P.

上記のとおり、固定具2が形成されている。次に、固定具2の効果を、作用と共に、図面を用いて説明する。図6ないし9は、固定具2の使用状態における概略が示されている。図6及び7は、固定具2が解除されて被固定部材1に着脱可能な状態(以下、「解除状態」と記す。)が示され、図8及び9は、固定具2が被固定部材1に固定された状態(以下、「固定状態」と記す。)が示されている。解除状態から固定状態への遷移を、仮固定状態と記す。 As described above, the fixative 2 is formed. Next, the effect of the fixative 2 together with the action will be described with reference to the drawings. 6 to 9 show an outline of the fixture 2 in a used state. 6 and 7 show a state in which the fixture 2 is released and can be attached to and detached from the fixed member 1 (hereinafter referred to as “released state”), and FIGS. 8 and 9 show the fixture 2 being a fixed member. The state fixed to 1 (hereinafter referred to as "fixed state") is shown. The transition from the released state to the fixed state is referred to as a temporary fixed state.

図6及び7に示されているとおり、解除状態では、操作部18は、後方(図7における左方)に倒れている。操作部18に伴って、軸部材8の弧状接触面13は、開口部7に対して支持孔5の内側に配置されている。すなわち、弧状接触面13は、本体部3の把持孔4の内周面から把持孔4の内側に張り出しておらず、把持孔4の外側又は内周面上に在って、被固定部材1から離れ、接触していない。したがって、被固定部材1が把持孔4に通されることにより、固定具2は、被固定部材1の任意の位置に配置される。 As shown in FIGS. 6 and 7, in the released state, the operation unit 18 is tilted backward (to the left in FIG. 7). Along with the operation unit 18, the arcuate contact surface 13 of the shaft member 8 is arranged inside the support hole 5 with respect to the opening 7. That is, the arc-shaped contact surface 13 does not project from the inner peripheral surface of the grip hole 4 of the main body 3 to the inside of the grip hole 4, but is present on the outer or inner peripheral surface of the grip hole 4 and is the fixed member 1. Away from and not in contact. Therefore, the fixture 2 is arranged at an arbitrary position of the fixed member 1 by passing the fixed member 1 through the gripping hole 4.

解除状態において、操作部18が、前方(図7における右方)に向かって徐々に倒されると、仮固定状態を経て、固定状態となる。図8及び9に示されているとおり、操作部18の動作に伴って、軸部材8が回転軸16を中心に回転し、軸部材8の弧状接触面13は、開口部7に対して支持孔5の外側に配置される。すなわち、偏心部10の偏心軸17が、回転軸16に対して偏心していることから、軸部材8の回転に伴って、偏心部10の弧状接触面13は、本体部3における把持孔4の内周面から、開口部7を通じて、把持孔4の内側に徐々に張り出し、被固定部材1を押さえ付ける。 When the operation unit 18 is gradually tilted forward (to the right in FIG. 7) in the released state, it goes through a temporary fixed state and becomes a fixed state. As shown in FIGS. 8 and 9, the shaft member 8 rotates about the rotating shaft 16 with the operation of the operation unit 18, and the arcuate contact surface 13 of the shaft member 8 supports the opening 7. It is arranged outside the hole 5. That is, since the eccentric shaft 17 of the eccentric portion 10 is eccentric with respect to the rotating shaft 16, the arcuate contact surface 13 of the eccentric portion 10 becomes the grip hole 4 in the main body portion 3 as the shaft member 8 rotates. From the inner peripheral surface, the member to be fixed 1 is pressed by gradually projecting from the inner peripheral surface to the inside of the gripping hole 4 through the opening 7.

仮固定状態では、弧状接触面13が把持孔4の内側に徐々に張り出すのにしたがって、被固定部材1を押さえ付ける度合いが増し、徐々に被固定部材1が押さえ付けられる。すなわち、操作部18が前方に向って倒れ始めれば、被固定部材1は押さえ付けられ、操作部18は、解除状態での姿勢から、鉛直に起立した姿勢、この姿勢から前方に倒れた姿勢等、姿勢が解除状態から前方に向けて変化する都度、被固定部材1が堅固に押さえ付けられる。したがって、仮固定状態であっても、固定具2を被固定部材1に固定することができる。固定状態であれば、さらに堅固に固定具2を被固定部材1に固定することができる。 In the temporarily fixed state, as the arc-shaped contact surface 13 gradually overhangs the inside of the grip hole 4, the degree of pressing the fixed member 1 increases, and the fixed member 1 is gradually pressed. That is, when the operation unit 18 begins to fall forward, the fixed member 1 is pressed down, and the operation unit 18 is in a vertically standing posture, a posture in which the operation unit 18 is tilted forward from this posture, and the like. Each time the posture changes from the released state to the front, the fixed member 1 is firmly pressed down. Therefore, the fixture 2 can be fixed to the fixed member 1 even in the temporarily fixed state. In the fixed state, the fixture 2 can be more firmly fixed to the fixed member 1.

弧状接触面13は、被固定部材1の側面形状に倣った曲面であるため、被固定部材1の側面と周方向に渡って接触する。被固定部材1と弧状接触面13との接触箇所が面状となるため、固定具2は、被固定部材1から外れ難い。そうであれば、両者がズレることで生じる被固定部材1の損傷や弧状接触面13の摩耗も抑止される。また、両者が面で接触することで、固定具2が被固定部材1に堅固に固定されることから、弧状接触面13を被固定部材1に押し付けるための弾性力を生じさせる部材等を、原則として要さず、その分、小型の設計が可能となる。さらに、このような部材等を要しない分、部品点数が少なくて済む。 Since the arc-shaped contact surface 13 is a curved surface that follows the shape of the side surface of the fixed member 1, it comes into contact with the side surface of the fixed member 1 in the circumferential direction. Since the contact point between the fixed member 1 and the arc-shaped contact surface 13 is planar, the fixture 2 is difficult to come off from the fixed member 1. If this is the case, damage to the fixed member 1 and wear of the arcuate contact surface 13 caused by the displacement between the two are also suppressed. Further, since the fixture 2 is firmly fixed to the fixed member 1 when the two come into contact with each other on the surface, a member or the like that generates an elastic force for pressing the arcuate contact surface 13 against the fixed member 1 can be used. As a general rule, it is not necessary, and a smaller design is possible accordingly. Further, since such a member is not required, the number of parts can be reduced.

固定具2では、軸部材8の弧状接触面13が、軸部材8における被支持部9の外周面よりも内側に形成されている。この構成により、弧状接触面13が被固定部材1に押し付けられると、軸部材8の回転軸16が、被固定部材1の外面に近づいた状態で、軸部材8が被固定部材1と交差する。すなわち、軸部材8が被固定部材1に近づく分、小型の設計が可能となる。 In the fixture 2, the arcuate contact surface 13 of the shaft member 8 is formed inside the outer peripheral surface of the supported portion 9 of the shaft member 8. With this configuration, when the arc-shaped contact surface 13 is pressed against the fixed member 1, the shaft member 8 intersects the fixed member 1 with the rotating shaft 16 of the shaft member 8 approaching the outer surface of the fixed member 1. .. That is, as the shaft member 8 approaches the fixed member 1, a compact design becomes possible.

固定具2では、軸部材8の偏心部10が、回転軸16に対して偏心し、かつ、被支持部9の外周面以内に形成されている。すなわち、連接面14によって、基部11が投影円周Pに揃えられていることから、偏心部10は、軸部材8上において、被支持部9の外周面と同一面上、または、この外周面よりも内側にあるため、偏心部10は、偏心しつつも被支持部9の外周面の外側に張り出していない。この構成により、固定具2の設計において、偏心部10の直径に依拠せずに、被支持部9の直径を軸部材8の直径とみなすことができ、設計や部材の組み付けが簡便である。 In the fixture 2, the eccentric portion 10 of the shaft member 8 is eccentric with respect to the rotating shaft 16 and is formed within the outer peripheral surface of the supported portion 9. That is, since the base portion 11 is aligned with the projected circumference P by the connecting surface 14, the eccentric portion 10 is on the same surface as the outer peripheral surface of the supported portion 9 or on the outer peripheral surface thereof on the shaft member 8. The eccentric portion 10 is eccentric but does not project to the outside of the outer peripheral surface of the supported portion 9. With this configuration, in the design of the fixture 2, the diameter of the supported portion 9 can be regarded as the diameter of the shaft member 8 without depending on the diameter of the eccentric portion 10, and the design and assembly of the members are simple.

固定具2の本体部3は、把持孔4と直交すると共に軸部材8が通された支持孔5と、この支持孔5と直交すると共に操作部18が通された操作孔6とが形成されている。すなわち、軸部材8と操作部18とが、別個の孔に通されて連結されるため、構成が簡便である。 The main body 3 of the fixture 2 is formed with a support hole 5 orthogonal to the grip hole 4 and through which the shaft member 8 is passed, and an operation hole 6 orthogonal to the support hole 5 and through which the operation portion 18 is passed. ing. That is, since the shaft member 8 and the operation unit 18 are connected through separate holes, the configuration is simple.

固定具2の操作部18は、操作孔6の中で、軸部材8における被支持部9の側面にネジ構造(被支持部側連結部15、操作部側連結部19)によって連結され、本体部3の外側に突出している。したがって、操作部18の動作と連動して、軸部材8が回転するため、操作が簡便である。 The operation portion 18 of the fixture 2 is connected to the side surface of the supported portion 9 of the shaft member 8 by a screw structure (supported portion side connecting portion 15, operating portion side connecting portion 19) in the operation hole 6, and is connected to the main body. It protrudes to the outside of the portion 3. Therefore, the shaft member 8 rotates in conjunction with the operation of the operation unit 18, so that the operation is simple.

固定具2の操作孔6は、前後方向に長い長孔であり、本体部3のうち、把持孔4を軸とした上外側面の右側寄りに形成され、操作部18は、操作孔6の範囲において、本体部3における把持孔4の軸方向である前後方向に動く。この構成により、操作部18の可動方向が、被固定部材1の長手方向となるため、固定具2が被固定部材1に対して取り付けられ、移動させられる方向と、操作部18の可動方向とが、同一方向に揃う。したがって、固定具2の扱いが簡便である。 The operation hole 6 of the fixture 2 is a long hole long in the front-rear direction, and is formed on the right side of the upper and outer surfaces of the main body 3 with the grip hole 4 as the axis. In the range, it moves in the front-rear direction, which is the axial direction of the grip hole 4 in the main body portion 3. With this configuration, the movable direction of the operation unit 18 is the longitudinal direction of the fixed member 1, so that the direction in which the fixture 2 is attached to and moved with respect to the fixed member 1 and the movable direction of the operation unit 18 However, they are aligned in the same direction. Therefore, the fixture 2 is easy to handle.

次に、本発明の第二参考例に係る固定具を図面に基づいて説明する。図10は、第二参考例に係る固定具202が示されている。なお、以下では、第一参考例に係る固定具2と異なる構成が主に説明され、固定具2と同様の構成は、第一参考例と同一符号が図示されることで、説明が適宜省略されている。 Next, the fixture according to the second reference example of the present invention will be described with reference to the drawings. FIG. 10 shows the fixture 202 according to the second reference example. In the following, a configuration different from the fixture 2 according to the first reference example will be mainly described, and the same configuration as the fixture 2 will be omitted as appropriate because the same reference numerals as those of the first reference example are shown. Has been done.

図10に示されているとおり、固定具202は、弧状接触面13(図6ないし9参照。)を被固定部材1に押し付けるための弾性力を生じさせる部材として、コイルバネ21を有している。詳説すれば、固定具202の本体部3は、コイルバネ21が通されるバネ孔20が形成されている。バネ孔20は、コイルバネ21に倣った円筒形であり、本体部3における前後外面の右上寄りを前後方向に貫通し、操作孔6と直交すると共に操作孔6に通じている。コイルバネ21は、バネ孔20に挿入され、コイルバネ21が挿入された後のバネ孔20は、ネジ構造等を有する蓋部材22が取り付けられることで閉じられている。 As shown in FIG. 10, the fixative 202 has a coil spring 21 as a member that generates an elastic force for pressing the arc-shaped contact surface 13 (see FIGS. 6 to 9) against the fixed member 1. .. More specifically, the main body 3 of the fixture 202 is formed with a spring hole 20 through which the coil spring 21 is passed. The spring hole 20 has a cylindrical shape that imitates the coil spring 21, penetrates the front and rear outer surfaces of the main body 3 toward the upper right in the front-rear direction, is orthogonal to the operation hole 6, and is connected to the operation hole 6. The coil spring 21 is inserted into the spring hole 20, and the spring hole 20 after the coil spring 21 is inserted is closed by attaching a lid member 22 having a screw structure or the like.

操作部18は、コイルバネ21の弾性力によって、前方に倒れる方向に押されているため、仮固定状態又は固定状態である。固定具202が、被固定部材1に取り付けられる際、操作部18が後方に倒されて解除状態となり、被固定部材1が把持孔4に通される。操作部18は、解放されると、コイルバネ21の弾性力によって自動的に前方に倒され、仮固定状態又は固定状態となる。したがって、操作部18が不本意に後方に倒されて解除状態となることを防ぐことができる。なお、コイルバネ21が操作部18を前方に押す力の程度は、コイルバネ21の自然長やバネ定数によって決定される。 Since the operation unit 18 is pushed in the direction of tilting forward by the elastic force of the coil spring 21, it is in a temporarily fixed state or a fixed state. When the fixture 202 is attached to the fixed member 1, the operation unit 18 is tilted backward to be in the released state, and the fixed member 1 is passed through the grip hole 4. When the operation unit 18 is released, it is automatically tilted forward by the elastic force of the coil spring 21, and is in a temporarily fixed state or a fixed state. Therefore, it is possible to prevent the operation unit 18 from being unintentionally tilted backward and in the released state. The degree of force that the coil spring 21 pushes the operation unit 18 forward is determined by the natural length of the coil spring 21 and the spring constant.

次に、本発明の実施形態に係る固定具を図面に基づいて説明する。図11及び12は、本実施形態に係る固定具302が示されている。なお、以下では、第一参考例に係る固定具2と異なる操作部の構成が主に説明され、固定具2と同様の構成は、第一参考例と同一符号が図示されることで、説明が適宜省略されている。 Next, the fixture according to the embodiment of the present invention will be described with reference to the drawings. 11 and 12 show the fixture 302 according to this embodiment. In the following, the configuration of the operation unit different from that of the fixing tool 2 according to the first reference example will be mainly described, and the same configuration as the fixing tool 2 will be described by showing the same reference numerals as those of the first reference example. Is omitted as appropriate.

図11及び12に示されているとおり、固定具302では、本体部303に形成された操作孔306は、本体部303のうち、把持孔4が形成された面である前面と同一面であって、右側寄りに形成された溝である。操作孔306は、前方から視して、溝の底である溝底部329を有している。また、換言すれば、操作孔306は、上下方向に本体部303を貫通し、本体部303のうち、上外側面側及び下外側面側が開放されている。操作孔306は、支持孔5と直交すると共に支持孔5に通じている。固定具302では、軸部材8の被支持部側連結部315は、右側の被支持部9の端部に形成されたネジ構造である。 As shown in FIGS. 11 and 12, in the fixture 302, the operation hole 306 formed in the main body 303 is the same surface as the front surface of the main body 303 in which the grip hole 4 is formed. It is a groove formed on the right side. The operation hole 306 has a groove bottom portion 329 which is the bottom of the groove when viewed from the front. In other words, the operation hole 306 penetrates the main body 303 in the vertical direction, and the upper outer surface side and the lower outer surface side of the main body 303 are opened. The operation hole 306 is orthogonal to the support hole 5 and leads to the support hole 5. In the fixture 302, the supported portion side connecting portion 315 of the shaft member 8 has a screw structure formed at the end portion of the supported portion 9 on the right side.

操作孔306に配置された操作部318は、長手の板状に形成された操作本体部323と、コイルバネ21とを有している。操作本体部323は、軸部材8と直交して連結された連結部としての操作部側連結部319と、この操作部側連結部319から操作孔306に沿って上方に伸びた操作端部324と、操作部側連結部319から操作孔306に沿って操作端部324と反対側である下方に伸びた弾性作用部325と、本体部303の上外側面から外側に突出した操作端部324に形成されて本体部303と対面した補助操作部326とを有している。コイルバネ21は、弾性作用部325に取り付けられている。 The operation unit 318 arranged in the operation hole 306 has an operation main body unit 323 formed in a long plate shape and a coil spring 21. The operation main body portion 323 includes an operation portion side connecting portion 319 as a connecting portion orthogonally connected to the shaft member 8, and an operation end portion 324 extending upward along the operation hole 306 from the operation portion side connecting portion 319. And the elastic action part 325 extending downward from the operation part side connecting part 319 along the operation hole 306 on the opposite side to the operation end part 324, and the operation end part 324 protruding outward from the upper outer surface of the main body part 303. It has an auxiliary operation unit 326 formed on the surface of the main body portion 303 and facing the main body portion 303. The coil spring 21 is attached to the elastic acting portion 325.

操作部側連結部319には、連結孔327が形成され、この連結孔327に軸部材8の被支持部側連結部315が接続されている。操作端部324は、操作部側連結部319から、上方かつ前方に向けて斜めに伸びている。操作端部324の先端は、本体部303の上外側面側から外側に突出している。操作端部324の先端は、手前側に向けて屈曲している。操作端部324の先端の左側面には、補助操作部326が連結されている。補助操作部326は、操作端部324と直交し、左方に向けて伸びると共に、本体部303の上側外側面又は前面と対面している。弾性作用部325は、操作部側連結部319から、下方かつ前方に向けて斜めに伸びている。したがって、操作部側連結部319が操作孔306の溝底部329から離れる距離と比較して、弾性作用部325の先端が溝底部329から離れる距離の方が大きい。操作端部324の先端のうち、溝底部329と対面する側は切り欠かれ、この切欠き部328にコイルバネ21が取り付けられている。コイルバネ21は、切欠き部328と溝底部329との間に配置されている。コイルバネ21は、自然長又は圧縮した状態で取り付けられている。したがって、弾性作用部325が伸びた方向について換言すれば、弾性作用部325は、操作部側連結部319から下方、かつ、圧縮したコイルバネ21が復元する方向に向けて伸びている。 A connecting hole 327 is formed in the operation portion side connecting portion 319, and the supported portion side connecting portion 315 of the shaft member 8 is connected to the connecting hole 327. The operation end portion 324 extends diagonally upward and forward from the operation portion side connecting portion 319. The tip of the operation end portion 324 projects outward from the upper / outer surface side of the main body portion 303. The tip of the operation end 324 is bent toward the front side. An auxiliary operation unit 326 is connected to the left side surface of the tip of the operation end portion 324. The auxiliary operation portion 326 is orthogonal to the operation end portion 324, extends to the left, and faces the upper outer surface or the front surface of the main body portion 303. The elastic action portion 325 extends diagonally downward and forward from the operation portion side connecting portion 319. Therefore, the distance at which the tip of the elastic acting portion 325 is separated from the groove bottom portion 329 is larger than the distance at which the operation portion side connecting portion 319 is separated from the groove bottom portion 329 of the operation hole 306. Of the tip of the operation end 324, the side facing the groove bottom 329 is cut out, and the coil spring 21 is attached to the notch 328. The coil spring 21 is arranged between the notch 328 and the groove bottom 329. The coil spring 21 is attached in a natural length or in a compressed state. Therefore, in other words, the elastic acting portion 325 extends downward from the operating portion side connecting portion 319 and toward the direction in which the compressed coil spring 21 is restored.

操作本体部323は、コイルバネ21の弾性力によって、操作端部324が後方(図12における右方)に倒れる方向に押され、仮固定状態又は固定状態である。固定具302が、被固定部材1に取り付けられる際、補助操作部326が操作され、操作端部324が前方(図12における左方)に倒されて解除状態となり、被固定部材1が把持孔4に通される。補助操作部326が解放されると、操作本体部323は、圧縮したコイルバネ21の弾性力によって操作端部324が自動的に後方に倒され、仮固定状態又は固定状態となる。 The operation main body portion 323 is in a temporarily fixed state or a fixed state by being pushed in a direction in which the operation end portion 324 is tilted rearward (to the right in FIG. 12) by the elastic force of the coil spring 21. When the fixture 302 is attached to the fixed member 1, the auxiliary operation portion 326 is operated, the operation end portion 324 is tilted forward (to the left in FIG. 12) to be in the released state, and the fixed member 1 is in the gripping hole. Passed through 4. When the auxiliary operation portion 326 is released, the operation end portion 324 of the operation main body portion 323 is automatically tilted backward by the elastic force of the compressed coil spring 21, and is in a temporarily fixed state or a fixed state.

操作部318は、操作部側連結部319に対して補助操作部326(操作端部324)と反対側にコイルバネ21を有しているため、軸部材8が接続されたことで回転中心となる操作部側連結部319から、操作による外力が作用する補助操作部326までの長さ、及び、コイルバネ21による弾性力が作用する弾性作用部325までの長さ相当分、小さい力でモーメントが生じる。したがって、操作がし易い。 Since the operation unit 318 has the coil spring 21 on the side opposite to the auxiliary operation unit 326 (operation end portion 324) with respect to the operation unit side connection unit 319, the shaft member 8 is connected to the operation unit 318 to become the center of rotation. A moment is generated with a small force corresponding to the length from the operation unit side connecting unit 319 to the auxiliary operation unit 326 on which the external force by the operation acts and the length to the elastic action unit 325 on which the elastic force by the coil spring 21 acts. .. Therefore, it is easy to operate.

特に、操作端部324の先端の左側面には、補助操作部326が連結され、この補助操作部326は、操作端部324と直交し、左方に向けて伸びると共に、本体部303の上側外側面又は前面と対面している。したがって、操作者が操作部318を操作する際、操作者は親指等を補助操作部326に当て易くなるため、操作がし易い。 In particular, an auxiliary operation unit 326 is connected to the left side surface of the tip of the operation end portion 324, and the auxiliary operation unit 326 is orthogonal to the operation end portion 324 and extends to the left and is above the main body portion 303. Facing the outer side or front. Therefore, when the operator operates the operation unit 318, the operator can easily put his / her thumb or the like on the auxiliary operation unit 326, so that the operation is easy.

弾性作用部325は、操作部側連結部319から、下方かつ前方に向けて斜めに伸びている。換言すれば、操作部側連結部319から下方、かつ、圧縮したコイルバネ21が復元する方向に向けて伸びている。この構成により、操作孔306において、操作部側連結部319が操作孔306の溝底部329から離れる距離と比較して、弾性作用部325の先端が溝底部329から離れる距離の方が大きいため、その分、大きなコイルバネ21を取り付けることができ、大きな弾性力をもって、軸部材8が操作本体部323と共に回転する。したがって、堅固に被固定部材1を押さえ付けることができる。また、大きなコイルバネ21が取り付けられた場合であっても、小さい力でモーメントを生じさせることができる。 The elastic action portion 325 extends diagonally downward and forward from the operation portion side connecting portion 319. In other words, the compressed coil spring 21 extends downward from the operation portion side connecting portion 319 toward the restoration direction. With this configuration, in the operation hole 306, the distance at which the tip of the elastic acting portion 325 is separated from the groove bottom portion 329 is larger than the distance at which the operation portion side connecting portion 319 is separated from the groove bottom portion 329 of the operation hole 306. By that amount, a large coil spring 21 can be attached, and the shaft member 8 rotates together with the operation main body portion 323 with a large elastic force. Therefore, the fixed member 1 can be firmly pressed down. Further, even when a large coil spring 21 is attached, a moment can be generated with a small force.

固定具302における他の効果は、固定具2と同様である。 Other effects of the fixative 302 are similar to the fixture 2.
