　特許文献１に開示される技術では、板バネがフック体のカム面に接触して、フック体の回転に応じて摺動する。またフック体に摺動抵抗を抑える表面処理を施すことは手間である。 In the technology disclosed in Patent Document 1, the leaf spring comes into contact with the cam surface of the hook body and slides in response to the rotation of the hook body. In addition, it is time-consuming to apply a surface treatment to the hook body to reduce sliding resistance.

　本発明の目的は、フックと金属バネの直接の摺動を抑え、製造を容易にするフック装置を提供することにある。 The object of the present invention is to provide a hook device that reduces direct sliding between the hook and the metal spring, making it easier to manufacture.

　上記課題を解決するために、本発明のある態様のフック装置は、樹脂材料によって形成されるベースと、金属材料によって形成され、ベースに対して回転可能に設けられるフックと、フックを付勢する金属バネと、を備える。フックは、先端側に位置する荷掛け部と、基端側にて対向して配置される一対の基端部と、基端部の外周に形成される当接面と、を有する。一対の基端部が対向する方向に沿ったフックの回転軸心が、一対の基端部を貫通して位置しており、ベースは、当接面および金属バネの間に介在する可撓片を有する。金属バネは、フックの回転軸心に向かって可撓片を介して当接面を付勢する。 In order to solve the above problems, a hook device according to one embodiment of the present invention comprises a base made of a resin material, a hook made of a metal material and rotatably mounted relative to the base, and a metal spring that biases the hook. The hook has a load-hanging portion located at the tip end, a pair of base ends arranged opposite each other at the base end, and an abutment surface formed on the outer periphery of the base ends. The axis of rotation of the hook, which runs along the direction in which the pair of base ends face each other, passes through the pair of base ends, and the base has a flexible piece interposed between the abutment surface and the metal spring. The metal spring biases the abutment surface via the flexible piece toward the axis of rotation of the hook.

　本発明によれば、フックと金属バネの直接の摺動を抑え、製造を容易にするフック装置を提供できる。 The present invention provides a hook device that reduces direct sliding between the hook and metal spring, making manufacturing easier.

The locking claw portion 32 locks with the bottom portion 26 to maintain the lid portion 30 in a closed state as shown in FIG. 1. After the hook device 10 is fixed to the mounting member by the screw 20, the lid portion 30 is closed. The hinge portion 34 is arranged parallel to the shaft 22.

　挿通孔３６は、対向する一対の側壁部２８にそれぞれ形成され、同軸に配置される。一対の挿通孔３６にはシャフト２２の両端が挿入される。操作孔３８は、底部２６に形成され、ネジ２０を回転させる工具を挿入可能に形成される。 The insertion holes 36 are formed in a pair of opposing side wall portions 28 and are arranged coaxially. Both ends of the shaft 22 are inserted into the pair of insertion holes 36. The operating hole 38 is formed in the bottom portion 26 and is configured so that a tool for rotating the screw 20 can be inserted.

　受け部４０は、図３（ａ）に示すように底部２６に孔状に一対形成される。受け部４０は、ブラケット１８に係合する。ピン部４２は、底部２６の裏面から柱状に突出して形成される。ピン部４２は、フック装置１０を被取付部材に取り付ける際の位置決めとして機能する。係止孔部４９は、図３（ａ）に示すように底部２６に一対形成され、係止爪部３２を係止する。 The receiving portions 40 are formed in a pair of holes in the bottom portion 26 as shown in FIG. 3(a). The receiving portions 40 engage with the bracket 18. The pin portions 42 are formed so as to protrude in a columnar shape from the rear surface of the bottom portion 26. The pin portions 42 function as positioning devices when attaching the hook device 10 to a workpiece. The locking holes 49 are formed in a pair in the bottom portion 26 as shown in FIG. 3(a) and lock the locking claw portions 32.

　突出部４４は、支持壁部２９から突出して片持ち梁として形成される。突出部４４は、フック１４の回転軸方向Ｘに直交する方向Ｙに突出し、柱状に形成される。突出部４４は、フック１４の回転軸方向Ｘに離間して一対設けられる。突出部４４は、図３（ｂ）に示すように、裏面から金属バネ１６に向かって突出する凸部４４ａを有する。 The protrusion 44 protrudes from the support wall 29 and is formed as a cantilever. The protrusion 44 protrudes in a direction Y perpendicular to the rotation axis direction X of the hook 14 and is formed in a columnar shape. A pair of protrusions 44 are provided spaced apart in the rotation axis direction X of the hook 14. As shown in FIG. 3(b), the protrusion 44 has a convex portion 44a that protrudes from the back surface toward the metal spring 16.

　可撓片４６は、突出部４４から回転軸方向Ｘに沿って延出する片持ち片として形成される。可撓片４６は、平板状に形成され、支持壁部２９から離間しており、上下方向に撓み可能である。スリット４７は、底部２６を切り欠くように形成され、突出部４４および可撓片４６の下方に位置する。 The flexible piece 46 is formed as a cantilever extending from the protruding portion 44 along the rotation axis direction X. The flexible piece 46 is formed in a flat plate shape, is spaced apart from the support wall portion 29, and is capable of bending in the vertical direction. The slit 47 is formed by cutting out the bottom portion 26, and is located below the protruding portion 44 and the flexible piece 46.

　支持部４８は、底部２６から支持壁部２９に亘って形成され、支持壁部２９から回転軸方向Ｘに直交する方向Ｙに沿って突出する。支持部４８は、一対の突出部４４の間に位置する。支持部４８の回転軸方向Ｘの両側にはスリット４７が設けられている。 The support portion 48 is formed from the bottom portion 26 to the support wall portion 29, and protrudes from the support wall portion 29 in a direction Y perpendicular to the rotation axis direction X. The support portion 48 is located between the pair of protruding portions 44. Slits 47 are provided on both sides of the support portion 48 in the rotation axis direction X.

　図２に戻る。ブラケット１８は、金属板材を切削加工、屈曲加工を施して形成される。ブラケット１８は、底部５６、立設部５８、支持孔部６０、回転止め部６２、ネジ固定孔６４、張出部６６および突出部６８を有する。 Returning to FIG. 2, the bracket 18 is formed by cutting and bending a metal plate. The bracket 18 has a bottom portion 56, an upright portion 58, a support hole portion 60, a rotation stop portion 62, a screw fixing hole 64, a protruding portion 66, and a protruding portion 68.

　立設部５８は、底部５６から屈曲して立設し、対向して一対形成される。支持孔部６０は、一対の立設部５８にそれぞれ形成される。一対の支持孔部６０は同軸に形成され、挿入されたシャフト２２を支持する。これにより、フック１４がシャフト２２を介してブラケット１８に回転可能に支持され、フック１４を引っ張る荷重はブラケット１８へ入力される。 The erected portions 58 are bent and erected from the bottom portion 56, and are formed as a pair facing each other. A support hole portion 60 is formed in each of the pair of erected portions 58. The pair of support holes 60 are formed coaxially and support the inserted shaft 22. As a result, the hook 14 is rotatably supported on the bracket 18 via the shaft 22, and the load pulling the hook 14 is input to the bracket 18.

　回転止め部６２は、立設部５８から内向きに張り出すように形成され、底部５６から上方に離れている。回転止め部６２は、フック１４の径方向凸部５４に当接して、フック１４の開き方向の回転を止める。ネジ固定孔６４は、ネジ２０を挿入可能に底部５６に形成される。ネジ固定孔６４は、ネジ２０の頭部より小さい。ブラケット１８は、ネジ２０によって被取付部材に固定される。 The rotation stopper 62 is formed to protrude inward from the upright portion 58 and is spaced upward from the bottom portion 56. The rotation stopper 62 abuts against the radial protrusion 54 of the hook 14 to stop the hook 14 from rotating in the opening direction. The screw fixing hole 64 is formed in the bottom portion 56 so that the screw 20 can be inserted. The screw fixing hole 64 is smaller than the head of the screw 20. The bracket 18 is fixed to the mounting member by the screw 20.

　張出部６６は、張り出すように一対形成される。張出部６６は、ベース１２の受け部４０に差し込まれて、ブラケット１８とベース１２を結合させる。 The protruding portions 66 are formed as a pair so as to protrude. The protruding portions 66 are inserted into the receiving portions 40 of the base 12 to connect the bracket 18 and the base 12.

　突出部６８は、一対の張出部６６の間に形成され、底部５６を屈曲して裏側に向かって突出する。突出部６８は、被取付部材の挿入孔に挿入され、その挿入孔に当たってフック装置１０の傾きを抑える。 The protrusion 68 is formed between the pair of overhanging portions 66, and bends the bottom portion 56 to protrude toward the back side. The protrusion 68 is inserted into the insertion hole of the workpiece, and prevents the hook device 10 from tilting when it comes into contact with the insertion hole.

　フック１４は、略Ｕ字状に形成され、ベース１２に対して回転可能に設けられ、シャフト２２を介してブラケット１８に支持される。フック１４は、金属板から形成できるため、安価である。フック１４の先端側に荷掛部５３が形成され、フック１４の両方の基端側に基端部５０がそれぞれ形成される。基端部５０は、対向して一対形成される。基端部５０は、中央に軸孔部５２を有し、シャフト２２を挿入可能である。フック１４の回転軸心は、一対の基端部５０の対向方向に沿っており、軸孔部５２の中心部を貫通する。 The hook 14 is formed in a roughly U-shape, is rotatably mounted on the base 12, and is supported by the bracket 18 via the shaft 22. The hook 14 is inexpensive because it can be formed from a metal plate. A load-hanging portion 53 is formed at the tip end of the hook 14, and a base end portion 50 is formed on each of the base ends of the hook 14. A pair of base ends 50 are formed opposite each other. The base end portion 50 has an axial hole portion 52 in the center, and the shaft 22 can be inserted into it. The axis of rotation of the hook 14 is aligned along the opposing direction of the pair of base ends 50, and passes through the center of the axial hole portion 52.

　基端部５０は、外周に当接面５５を有する。当接面５５は、周方向に亘って軸孔部５２からの径が変化するように滑らかに形成されており、可撓片４６を摺動させるカム面を構成する。径方向凸部５４は、基端部５０の外周面から径方向外向きに突出する。径方向凸部５４は、フック１４の回転を止めるストッパとして機能する。 The base end 50 has an abutment surface 55 on its outer periphery. The abutment surface 55 is formed smoothly so that the diameter from the shaft hole 52 changes circumferentially, and constitutes a cam surface that slides the flexible piece 46. The radial protrusion 54 protrudes radially outward from the outer periphery of the base end 50. The radial protrusion 54 functions as a stopper that stops the rotation of the hook 14.

　金属バネ１６は、帯状に形成された板バネであり、フック１４の当接面５５を付勢する。金属バネ１６は、弾性片７０および中央部７２を有する。中央部７２は、金属バネ１６の中央に位置し、逆Ｕ字状に形成される、中央部７２は、ベース１２の支持部４８係合し、支持部４８に支持される。弾性片７０は、一対形成され、中央部７２の両側から回転軸方向Ｘに沿ってそれぞれ延出する。弾性片７０は、中央部７２に連結する根元部７０ａから先端部７０ｂへ延出する。金属バネ１６の付勢により、図１に示すフック１４が収容状態や、全開状態に維持される。 The metal spring 16 is a flat spring formed in a band shape, and biases the contact surface 55 of the hook 14. The metal spring 16 has an elastic piece 70 and a central portion 72. The central portion 72 is located in the center of the metal spring 16 and is formed in an inverted U shape. The central portion 72 engages with the support portion 48 of the base 12 and is supported by the support portion 48. The elastic pieces 70 are formed as a pair and extend from both sides of the central portion 72 along the rotation axis direction X. The elastic piece 70 extends from a root portion 70a connected to the central portion 72 to a tip portion 70b. The bias of the metal spring 16 keeps the hook 14 shown in FIG. 1 in a stored state or a fully open state.

　シャフト２２は、円柱状に形成され、ベース１２の挿通孔３６、フック１４の軸孔部５２および金属バネ１６に挿入される。シャフト２２は、一端部に抜け止めとなる大径部２２ａを有する。ワッシャー２４は、軟質材で形成され、ベース１２のピン部４２およびブラケット１８の突出部６８を挿入可能である。ワッシャー２４は、被取付部材の挿入孔から異物が混入することを抑える。 The shaft 22 is formed in a cylindrical shape and is inserted into the insertion hole 36 of the base 12, the axial hole portion 52 of the hook 14, and the metal spring 16. The shaft 22 has a large diameter portion 22a at one end that prevents it from coming loose. The washer 24 is formed from a soft material, and the pin portion 42 of the base 12 and the protrusion portion 68 of the bracket 18 can be inserted into it. The washer 24 prevents foreign matter from entering through the insertion hole of the mounting member.

　図４は、フック１４およびシャフト２２を組み付ける前のフック装置１０の斜視図である。フック１４の軸孔部５２がブラケット１８の支持孔部６０に位置を合わされ、シャフト２２が軸孔部５２および支持孔部６０に挿入されて、フック装置１０の組み立てが完成する。ベース１２の蓋部３０は開いた状態である。 Figure 4 is a perspective view of the hook device 10 before the hook 14 and shaft 22 are assembled. The shaft hole 52 of the hook 14 is aligned with the support hole 60 of the bracket 18, and the shaft 22 is inserted into the shaft hole 52 and support hole 60, completing the assembly of the hook device 10. The lid 30 of the base 12 is in an open state.

　金属バネ１６は、突出部４４および可撓片４６の裏側に配置され、支持部４８に支持される。金属バネ１６の中央部７２は、支持部４８に載置されて凹凸で係合する。一対の可撓片４６は、一対の弾性片７０の表側にそれぞれ配置される。可撓片４６は、弾性片７０と同じ幅または弾性片７０よりも大きい幅を有し、弾性片７０を覆う。 The metal spring 16 is disposed on the rear side of the protrusion 44 and the flexible piece 46, and is supported by the support part 48. The central part 72 of the metal spring 16 is placed on the support part 48 and engages with the unevenness. The pair of flexible pieces 46 are disposed on the front side of the pair of elastic pieces 70, respectively. The flexible pieces 46 have the same width as the elastic pieces 70 or a width greater than that of the elastic pieces 70, and cover the elastic pieces 70.

　支持部４８は、一対の突出部４４の間に配置され、突出部４４よりも底部２６側の低い位置に設けられる。突出部４４および可撓片４６は、底部２６よりも表側（上方）に高い位置に形成される。また、弾性片７０は、底部２６の面直方向、すなわち上下方向において、突出部４４および可撓片４６と、底部２６との間に配置される。そのため、作業者は、金属バネ１６を底部２６に載せ、底部２６に沿って支持壁部２９に向かってスライドさせれば、金属バネ１６を容易に組み付けることができる。 The support portion 48 is disposed between a pair of protrusions 44, and is provided at a lower position on the bottom 26 side than the protrusions 44. The protrusions 44 and the flexible piece 46 are formed at a higher position on the front side (upward) than the bottom 26. The elastic piece 70 is also disposed between the protrusions 44 and the flexible piece 46, and the bottom 26 in the direction perpendicular to the surface of the bottom 26, i.e., in the up-down direction. Therefore, the worker can easily assemble the metal spring 16 by placing the metal spring 16 on the bottom 26 and sliding it along the bottom 26 toward the support wall portion 29.

　凸部４４ａは、金属バネ１６に向かって裏側に突出している。凸部４４ａによって突出部４４の剛性が向上し、可撓片４６の支持性が向上する。これにより、可撓片４６の弾性を高めることが可能になり、可撓片４６がフック１４を付勢するように構成できる。 The protrusion 44a protrudes from the rear side toward the metal spring 16. The protrusion 44a improves the rigidity of the protrusion 44, improving the support of the flexible piece 46. This makes it possible to increase the elasticity of the flexible piece 46, and the flexible piece 46 can be configured to bias the hook 14.

　凸部４４ａは、裏側に向かって支持壁部２９に近づくようにテーパ状に形成されてよい。これにより、金属バネ１６を支持壁部２９に向かってスライドして組み付ける際にガイドとして機能できる。 The protrusion 44a may be tapered so that it approaches the support wall 29 toward the back side. This allows it to function as a guide when the metal spring 16 is slid toward the support wall 29 for assembly.

　図５は、図１に示すフック装置１０の線分Ｂ－Ｂ断面図である。また、図６は、図５に示すフック装置１０の線分Ｃ－Ｃ断面図である。フック装置１０の裏側の底面にはブラケット１８が配置される。ベース１２は、ブラケット１８に載った状態にあり、底部２６はブラケット１８の表側に位置する。 FIG. 5 is a cross-sectional view of the hook device 10 shown in FIG. 1 taken along line B-B. FIG. 6 is a cross-sectional view of the hook device 10 shown in FIG. 5 taken along line C-C. A bracket 18 is disposed on the bottom surface on the rear side of the hook device 10. The base 12 rests on the bracket 18, with the bottom 26 located on the front side of the bracket 18.

　シャフト２２は、挿通孔３６、支持孔部６０、軸孔部５２に挿入されている。立設部５８は、側壁部２８の内側に配置され、フック１４の軸孔部５２は立設部５８の内側に配置される。金属バネ１６の弾性片７０は、フック１４の回転軸心に向かって可撓片４６を介して当接面５５を付勢する。 The shaft 22 is inserted into the insertion hole 36, the support hole 60, and the axial hole 52. The erected portion 58 is disposed inside the side wall portion 28, and the axial hole 52 of the hook 14 is disposed inside the erected portion 58. The elastic piece 70 of the metal spring 16 biases the contact surface 55 toward the rotation axis of the hook 14 via the flexible piece 46.

　可撓片４６は、突出部４４に連結する根元部４６ａから先端部４６ｂに向かって軸方向Ｘに沿って延出する。可撓片４６は、基端部５０の周りで金属バネ１６と対向して配置され、金属バネ１６によって当接面５５に押し当てられる。可撓片４６は、当接面５５と金属バネ１６の間に介在する。可撓片４６により、金属材料であるフック１４および金属バネ１６の接触を防ぎ、金属部品同士の摺動を防ぐことができる。そのため、フック１４が高価な表面処理を施されなくても耐久性を向上できる。フック１４の表面処理の工程を減らせばフック装置１０の製造が容易になる。 The flexible piece 46 extends from the root portion 46a connected to the protrusion 44 toward the tip portion 46b along the axial direction X. The flexible piece 46 is disposed facing the metal spring 16 around the base end portion 50, and is pressed against the abutment surface 55 by the metal spring 16. The flexible piece 46 is interposed between the abutment surface 55 and the metal spring 16. The flexible piece 46 prevents contact between the hook 14 and the metal spring 16, which are made of metal materials, and prevents sliding between the metal parts. This improves durability even if the hook 14 is not subjected to expensive surface treatment. Reducing the surface treatment process for the hook 14 makes it easier to manufacture the hook device 10.

　可撓片４６は、側面から見て金属バネ１６の弾性片７０と略平行に延在する。これにより、可撓片４６は弾性片７０と同様に撓むことができ、フック１４の回転時に当接面５５に追従できる。 The flexible piece 46 extends approximately parallel to the elastic piece 70 of the metal spring 16 when viewed from the side. This allows the flexible piece 46 to bend in the same way as the elastic piece 70, and to follow the contact surface 55 when the hook 14 rotates.

　突出部４４が片持ち梁であり、可撓片４６が突出部４４から延出する片持ち片であるため、可撓片４６が上下に撓みやすくなっており、当接面５５への追従性が高められている。 Since the protrusion 44 is a cantilever and the flexible piece 46 is a cantilever extending from the protrusion 44, the flexible piece 46 is easily bent up and down, improving the ability to follow the contact surface 55.

　可撓片４６は、弾性片７０よりも回転軸方向Ｘの外向き、すなわち回転軸方向Ｘに沿って中央から離れる方向に長くなっている。これにより、弾性片７０がフック１４に接触することを抑えられる。 The flexible piece 46 is longer outward in the direction of the rotation axis X than the elastic piece 70, that is, in the direction away from the center along the direction of the rotation axis X. This prevents the elastic piece 70 from coming into contact with the hook 14.

　図６に示すフック１４がベース１２の底面に沿った閉状態において、当接面５５のうち可撓片４６の先端部４６ｂが当接している面は、上下方向において、可撓片４６の根元部４６ａと金属バネ１６の弾性片７０の根元部７０ａとの間に位置する。つまり、可撓片４６の根元部４６ａと弾性片７０の根元部７０ａは、当接面５５を挟んで離れて位置し、可撓片４６と金属ばね７０はそれぞれの先端部４６ｂ，７０ｂが作動するので、可撓片４６と金属ばね７０の中間部分から根元部４６ａ，７０ａが作動時に干渉することを防ぐことができる。 6, when the hook 14 is in the closed state along the bottom surface of the base 12, the surface of the abutment surface 55 against which the tip 46b of the flexible piece 46 abuts is located between the root 46a of the flexible piece 46 and the root 70a of the elastic piece 70 of the metal spring 16 in the vertical direction. In other words, the root 46a of the flexible piece 46 and the root 70a of the elastic piece 70 are located apart across the abutment surface 55, and the tip portions 46b, 70b of the flexible piece 46 and the metal spring 70 are actuated, so that the root portions 46a, 70a can be prevented from interfering with each other from the intermediate portion of the flexible piece 46 and the metal spring 70 during actuation.

As long as the metal spring 16 biases the contact surface 55 of the hook 14 and the flexible piece 46 is located between the metal spring 16 and the contact surface 55, the metal spring 16 may be a coil metal spring or a disc metal spring, and may be provided individually for each pair of contact surfaces 55.

　実施例では、可撓片４６が突出部４４から延出する態様を示したが、この態様に限られない。例えば、可撓片が側壁部２８や支持壁部２９から直接延出してもよい。 In the embodiment, the flexible piece 46 extends from the protruding portion 44, but this is not limited to the above. For example, the flexible piece may extend directly from the side wall portion 28 or the support wall portion 29.
