Description

本考案は、ランドセル、リュックサック、ショルダーバッグ、手提げバッグ等のバッグなどに取り付けられる吊下具に関する。 The present invention relates to a hanging tool attached to a bag such as a school bag, a rucksack, a shoulder bag, and a handbag.

従来、ランドセル側面の補助バンドに取り付けられる第一の部材と、第一の部材に連結される第二の部材と、第二の部材に備えられるフックを有した吊下げ部材とを備える吊下げ具が知られている（特許文献１参照）。
第一の部材は楕円形状の軸を有しており、第二の部材は軸が配置される軸穴を形成した一対の挟持片を有している。一対の挟持片間に形成された連通路の幅は、軸の軸線と直交する向きの断面が短い側の軸幅よりも大きく、当該断面が長い側の軸幅よりも小さく形成されている。このため、軸をその断面が短い側から連通路を通じて軸穴に収め入れることで第二の部材を第一の部材に連結することができる一方、第二の部材の垂設状態では軸の断面が長い側が連通路側に位置して第二の部材が第一の部材から外れない状態となる。
この第二の部材の垂設状態では、第二の部材は第一の部材に対して軸周りに回動可能であるので、首振り可能な吊下げ具が構成される。 Conventionally, a hanging tool comprising a first member attached to an auxiliary band on the side surface of the school bag, a second member connected to the first member, and a hanging member having a hook provided to the second member. Is known (see Patent Document 1).
The first member has an elliptical shaft, and the second member has a pair of clamping pieces in which a shaft hole in which the shaft is disposed is formed. The width of the communication path formed between the pair of sandwiching pieces is larger than the axial width on the short side in the direction perpendicular to the axis of the shaft, and smaller than the axial width on the long side. For this reason, the second member can be connected to the first member by inserting the shaft into the shaft hole from the side having the short cross section through the communication path, while the shaft cross section in the suspended state of the second member. The long side is located on the communication path side and the second member is not detached from the first member.
In the suspended state of the second member, the second member can rotate around the axis with respect to the first member, so that a hanging tool capable of swinging is configured.

特開平１０−７１０１３号公報Japanese Patent Laid-Open No. 10-71013

ところで、特許文献１に記載の吊下げ具では、吊下げ部材に吊り下げられた物品が器物などに引っ掛かった場合には、第二の部材が回動されて軸の断面が短い側が連通路側に位置する特定向きとなることで、第二の部材が第一の部材から外れて前記物品や吊下げ具に過度の力が加わることを防止している。
しかし、このような吊下げ具では、第二の部材が第一の部材に対して特定向きとなるまで回動しなければ、第二の部材が第一の部材から外れることがなく、このように回動を生じなかった場合には物品や吊下げ具に過度な力が加わるおそれがある。 By the way, in the hanging tool described in Patent Document 1, when the article suspended by the hanging member is caught on an object or the like, the second member is rotated and the side with the shorter cross section of the shaft is the communication path side. The second member is prevented from being detached from the first member and applying excessive force to the article and the hanging tool.
However, in such a hanging tool, the second member does not come off the first member unless the second member rotates until the second member is in a specific direction with respect to the first member. If there is no rotation, there is a risk that an excessive force is applied to the article or the hanging tool.

本考案の目的は、過負荷時にフックを円滑に外すことができる吊下具を提供することにある。 An object of the present invention is to provide a hanging tool that can smoothly remove a hook when overloaded.

本考案の吊下具は、被差込部が形成されたベース体と、前記被差込部に差し込まれる差込部および前記差込部につながったフック部を有した吊下体とを備えており、前記被差込部および前記差込部のうちのいずれか一方には、前記差込部の差込方向に直交する厚さ方向に窪んだ周面円弧状の係合穴部が形成されており、前記被差込部および前記差込部のうちのいずれか他方には、前記係合穴部に係合する周面円弧状の係合爪部が前記厚さ方向に突出して形成されており、前記係合穴部と前記係合爪部のうちの少なくとも一方の周面のうち前記他方の周面に圧接する面領域は、前記差込方向に対して傾斜していると共に、前記係合穴部に対して前記厚さ方向に離間する移動を前記係合爪部に生じさせる構成とされていることを特徴とする。
本考案の吊下具によれば、互いに係合する係合穴部および係合爪部の周面が円弧状に形成されているので、差込部の差込方向に直交する厚さ方向に沿った軸心周りで吊下体を回動させることができ、首振り可能な吊下具を構成できる。その上、例えばフック部に過度な引き抜き力が加えられた場合には、吊下体がベース体に対してどの回動角度にあっても、係合穴部と係合爪部のうちの少なくとも一方の周面の前記面領域が他方の周面に圧接することで、前記厚さ方向において係合爪部が係合穴部から離間移動して係合が解除され、吊下体をベース体から外すことができ、これにより、吊下具に過度な力が加えられることを防止できる。 The hanging tool of the present invention includes a base body in which a plugged portion is formed, a plugged portion inserted into the plugged portion, and a suspended body having a hook portion connected to the plugged portion. In either one of the inserted portion and the insertion portion, an engagement hole portion having a circular arc surface that is recessed in the thickness direction orthogonal to the insertion direction of the insertion portion is formed. An engagement claw portion having a circular arc shape that engages with the engagement hole portion is formed to protrude in the thickness direction on the other of the insertion portion and the insertion portion. A surface region that is in pressure contact with the other peripheral surface of at least one of the engaging hole portion and the engaging claw portion is inclined with respect to the insertion direction, and The engagement claw portion is configured to cause the engagement claw portion to move away from the engagement hole portion in the thickness direction.
According to the hanging tool of the present invention, since the peripheral surfaces of the engaging hole portion and the engaging claw portion that are engaged with each other are formed in an arc shape, in the thickness direction orthogonal to the inserting direction of the inserting portion. The suspension body can be rotated around the axial center along which the suspension can swing. In addition, for example, when an excessive pulling force is applied to the hook portion, at least one of the engagement hole portion and the engagement claw portion regardless of the rotation angle of the suspension body with respect to the base body. When the surface area of the peripheral surface is in pressure contact with the other peripheral surface, the engagement claw portion moves away from the engagement hole portion in the thickness direction, and the engagement is released, and the suspended body is removed from the base body. This can prevent excessive force from being applied to the hanger.

本考案の吊下具では、前記フック部は、縦片部と、前記縦片部に連続した底片部と、前記底片部に連続した立上げ片部とを有しており、前記縦片部および前記立上げ片部の間に形成されたフック開口には、当該フック開口を開閉可能な閉鎖部材が配置されており、前記縦片部には、前記差込方向および前記厚さ方向に直交する幅方向に沿ったスリットが形成されていてもよい。
このような構成によれば、縦片部のうち前記スリットが形成された部分の厚さ寸法が小さくなるので、例えばフック部に過度な引き下げ力が加えられた場合に縦片部に厚さ方向の弾性変形を生じさせることができ、この弾性変形によって吊下体が破損することを抑制できる。 In the hanging device of the present invention, the hook portion has a vertical piece portion, a bottom piece portion continuous with the vertical piece portion, and a rising piece portion continuous with the bottom piece portion, and the vertical piece portion A closing member capable of opening and closing the hook opening is disposed in the hook opening formed between the rising pieces, and the vertical piece is orthogonal to the insertion direction and the thickness direction. A slit along the width direction may be formed.
According to such a configuration, since the thickness dimension of the portion in which the slit is formed in the vertical piece portion is reduced, for example, when an excessive pulling force is applied to the hook portion, the thickness direction is applied to the vertical piece portion. The elastic deformation can be caused and the suspension of the suspended body can be suppressed by this elastic deformation.

本考案の吊下具では、前記フック部は、前記差込部に対して、前記差込方向および前記厚さ方向に直交する幅方向に沿った軸周りに回動可能に連結されていてもよい。
このような構成によれば、フック部を前記厚さ方向に沿った軸周りに回動可能なうえ、
前記幅方向に沿った軸周りにも回動可能な吊下具を構成できる。 In the hanging tool of the present invention, the hook portion may be connected to the insertion portion so as to be rotatable around an axis along a width direction orthogonal to the insertion direction and the thickness direction. Good.
According to such a configuration, the hook part can be rotated around an axis along the thickness direction,
A hanging tool that can also be rotated around an axis along the width direction can be configured.

本考案の吊下具では、前記係合爪部が形成された前記差込部または前記ベース体には、前記係合爪部が前記厚さ方向に進退可能な孔部が形成されていてもよい。
このような構成によれば、係合爪部を孔部に入り込ませることができるので、差込部やベース体の厚さ寸法を小さくでき、吊下具の薄型化を図ることができる。 In the hanging device of the present invention, the insertion portion or the base body in which the engagement claw portion is formed may have a hole portion through which the engagement claw portion can advance and retreat in the thickness direction. Good.
According to such a configuration, since the engaging claw portion can be inserted into the hole portion, the thickness dimension of the insertion portion and the base body can be reduced, and the hanging tool can be thinned.

本考案によれば、過負荷時にフックを円滑に外すことができる吊下具を提供することができる。 ADVANTAGE OF THE INVENTION According to this invention, the hanging tool which can remove a hook smoothly at the time of an overload can be provided.

ベース体１０は合成樹脂製であり、図２〜図４に示すように、ランドセルの側面部などに取り付けられる裏板部１１と、裏板部１１に沿った表板部１２と、裏板部１１および表板部１２を連結した連結部１３とを有しており、裏板部１１、表板部１２および連結部１３によって被差込部１５が形成されている。 The base body 10 is made of a synthetic resin, and as shown in FIGS. 2 to 4, a back plate portion 11 attached to a side portion of the school bag, a front plate portion 12 along the back plate portion 11, and a back plate portion 11 and a connecting portion 13 that connects the front plate portion 12, and the inserted portion 15 is formed by the back plate portion 11, the front plate portion 12, and the connecting portion 13.

裏板部１１は、略矩形板状に形成されていると共にＺ軸方向に突出した二つの取付軸１１１（図３参照）が形成されている。また、裏板部１１にはＺ軸方向に貫通した孔部１１２が形成されている。
表板部１２は略楕円板状に形成されており、表板部１２の裏板部１１に対向する内面１２１に係合穴部１６が形成されている。第１実施形態における係合穴部１６は有底であり、表板部１２の内面１２１から表側に向かって凹状に形成されている。
連結部１３は表板部１２の周縁のうち上側半分の領域に連続しており、裏板部１１および表板部１２が連結部１３によってつながれていない領域には被差込部１５の開口１５Ａが形成されている。 The back plate portion 11 is formed in a substantially rectangular plate shape and has two attachment shafts 111 (see FIG. 3) protruding in the Z-axis direction. Further, the back plate portion 11 is formed with a hole portion 112 penetrating in the Z-axis direction.
The front plate portion 12 is formed in a substantially elliptical plate shape, and the engagement hole portion 16 is formed in the inner surface 121 of the front plate portion 12 that faces the back plate portion 11. The engagement hole 16 in the first embodiment has a bottom, and is formed in a concave shape from the inner surface 121 of the front plate portion 12 toward the front side.
The connecting portion 13 is continuous with the upper half region of the periphery of the front plate portion 12, and the opening 15 A of the inserted portion 15 is provided in a region where the back plate portion 11 and the front plate portion 12 are not connected by the connecting portion 13. Is formed.

係合穴部１６は、図４に示すようにＺ軸方向に窪んで形成されていると共に周面１６１はその全周にわたって円弧状に形成されている。なお、本実施形態では周面１６１はＺ軸方向に沿っている。 As shown in FIG. 4, the engagement hole 16 is formed to be depressed in the Z-axis direction, and the peripheral surface 161 is formed in an arc shape over the entire periphery. In the present embodiment, the peripheral surface 161 is along the Z-axis direction.

吊下体２０は合成樹脂製であり、図２〜図４に示すように、被差込部１５に差し込まれる差込部２１と、差込部２１につながったフック部２２とを有している。第１実施形態では、差込部２１およびフック部２２は一体に連続している。
差込部２１は、円弧板状に形成されて吊下体２０の頭部を構成していると共に、Ｚ軸方向に貫通した孔部２１１が形成されている。この孔部２１１には、後述する係合爪部２５がＺ軸方向に進退可能に配置される。 The suspended body 20 is made of a synthetic resin, and has an insertion portion 21 to be inserted into the insertion portion 15 and a hook portion 22 connected to the insertion portion 21 as shown in FIGS. . In the first embodiment, the insertion portion 21 and the hook portion 22 are integrally continuous.
The insertion part 21 is formed in the shape of a circular arc plate to form the head of the suspended body 20 and is formed with a hole 211 penetrating in the Z-axis direction. An engagement claw portion 25 described later is disposed in the hole portion 211 so as to be movable back and forth in the Z-axis direction.

差込部２１には、孔部２１１の上部から下方に延出した係合爪部２５が形成されている。係合爪部２５の周面２５１はその全周にわたって円弧状に形成されている。係合爪部２５は、その上部から下部に向かってＺ軸方向の厚さ寸法が大きくなっており、上部よりも下方側で吊下具１の表側に突出している。係合爪部２５の係合穴部１６に対向する面（表面）は、その下部が上部よりも表側に位置するように斜め下に傾斜した傾斜面２５２とされている。係合爪部２５の周面２５１のうちフック部２２側に位置する面領域、すなわち、周面２５１のうち係合穴部１６の周面１６１に圧接する面領域は、吊下体２０のベース体１０に対する差込方向Ａに対して傾斜しており、第１実施形態では、係合爪部２５および係合穴部１６の係合状態で差込部２１側から係合穴部１６側に向かうに連れて斜め上に傾斜した傾斜面２５３によって形成されている。傾斜面２５３は図４に示すように平らな面であってもよいが、凹状または凸状に湾曲した曲面であってもよい。また、係合爪部２５には、傾斜面２５３よりも下方に延出した延出部２５４が形成されており、この延出部２５４があることで係合爪部２５が係合穴部１６に過度に入り込むことを規制している。 The insertion portion 21 is formed with an engaging claw portion 25 extending downward from the upper portion of the hole portion 211. The circumferential surface 251 of the engaging claw portion 25 is formed in an arc shape over the entire circumference. The engaging claw portion 25 has a thickness dimension in the Z-axis direction that increases from the upper portion toward the lower portion, and protrudes to the front side of the hanger 1 below the upper portion. A surface (front surface) of the engagement claw portion 25 that faces the engagement hole portion 16 is an inclined surface 252 that is inclined downward so that a lower portion thereof is positioned on the front side of the upper portion. A surface region located on the hook portion 22 side in the peripheral surface 251 of the engaging claw portion 25, that is, a surface region in pressure contact with the peripheral surface 161 of the engaging hole portion 16 in the peripheral surface 251 is a base body of the suspended body 20. In the first embodiment, the engaging claw portion 25 and the engaging hole portion 16 are engaged from the inserting portion 21 side toward the engaging hole portion 16 side. Is formed by an inclined surface 253 inclined obliquely upward. The inclined surface 253 may be a flat surface as shown in FIG. 4, or may be a curved surface curved in a concave shape or a convex shape. Further, the engaging claw portion 25 is formed with an extending portion 254 that extends downward from the inclined surface 253, and the engaging claw portion 25 is engaged with the engaging hole portion 16 by the presence of the extending portion 254. Restricting excessive entry into

フック部２２は、差込部２１に連続した縦片部２２１と、縦片部２２１に連続した底片部２２２と、底片部２２２に連続した立上げ片部２２３とを有しており、縦片部２２１および立上げ片部２２３の間に形成されたフック開口２２４には、当該フック開口２２４を開閉可能な閉鎖部材としての金属製のバネ部材２６が配置されている。
縦片部２２１の裏面２２１Ａ側には、Ｙ軸方向に沿ったスリット２２５が形成されている。スリット２２５のＺ軸方向における深さ寸法は、縦片部２２１のうちスリット２２５が形成された周辺部分のＺ軸方向における厚さ寸法の半分以上の寸法を有している。縦片部２２１のうちスリット２２５が形成された部分の厚さ寸法は、その周辺部分の厚さ寸法と比べて半分以下の寸法となるので、縦片部２２１のうちスリット２２５が形成された部分は弾性変形を生じやすい弾性変形部２２６として構成される。 The hook portion 22 includes a vertical piece portion 221 that is continuous with the insertion portion 21, a bottom piece portion 222 that is continuous with the vertical piece portion 221, and a rising piece portion 223 that is continuous with the bottom piece portion 222. A metal spring member 26 as a closing member capable of opening and closing the hook opening 224 is disposed in the hook opening 224 formed between the portion 221 and the rising piece 223.
A slit 225 along the Y-axis direction is formed on the back surface 221 A side of the vertical piece 221. The depth dimension of the slit 225 in the Z-axis direction is more than half the thickness dimension in the Z-axis direction of the peripheral portion of the vertical piece 221 where the slit 225 is formed. Since the thickness dimension of the portion where the slit 225 is formed in the vertical piece portion 221 is less than half the thickness of the peripheral portion, the portion of the vertical piece portion 221 where the slit 225 is formed Is configured as an elastic deformation portion 226 that is susceptible to elastic deformation.

本実施形態に係る吊下具１の組立手順は概ね次の通りである。先ず、ベース体１０の裏板部１１をランドセルの側面部に取り付ける。次に、吊下体２０の差込部２１をベース体１０の被差込部１５に差し込んで係合爪部２５を係合穴部１６にスナップフィット式に係合する。このとき、吊下体２０の差込方向ＡがＸ軸方向に対して左右に傾いた向きであっても、差込部２１を被差込部１５の開口１５Ａに差し込むことが可能である。
係合爪部２５および係合穴部１６の係合状態では、図４に示すように差込部２１が裏板部１１に当接すると共に傾斜面２５３が周面１６１に当接することで、吊下体２０がベース体１０に保持された状態となる。また、係合爪部２５の円弧状の周面２５１および係合穴部１６の円弧状の周面１６１同士が対面するので、吊下体２０は開口１５Ａの幅内において図１に示すＲ方向に回動（首振り）可能となっている。このようにして吊下具１を組み立てる。 The assembly procedure of the hanging tool 1 according to this embodiment is generally as follows. First, the back plate part 11 of the base body 10 is attached to the side part of the school bag. Next, the insertion portion 21 of the suspended body 20 is inserted into the insertion portion 15 of the base body 10, and the engagement claw portion 25 is engaged with the engagement hole portion 16 in a snap-fit manner. At this time, even if the insertion direction A of the suspended body 20 is inclined to the left and right with respect to the X-axis direction, the insertion portion 21 can be inserted into the opening 15A of the insertion portion 15.
In the engaged state of the engaging claw portion 25 and the engaging hole portion 16, the insertion portion 21 contacts the back plate portion 11 and the inclined surface 253 contacts the circumferential surface 161 as shown in FIG. The lower body 20 is held by the base body 10. Further, since the arc-shaped peripheral surface 251 of the engaging claw portion 25 and the arc-shaped peripheral surface 161 of the engaging hole portion 16 face each other, the suspended body 20 is in the R direction shown in FIG. 1 within the width of the opening 15A. It can be turned (swinged). In this way, the hanging tool 1 is assembled.

以上の吊下具１では、フック部２２に大きな引き抜き力（差込方向Ａとは逆方向の力）が加えられた場合には、縦片部２２１の弾性変形部２２６が弾性変形して吊下体２０の破損を抑制する。フック部２２に更に過度に大きな引き抜き力が加えられた場合には、係合爪部２５の傾斜面２５３が係合穴部１６の周面１６１に対して滑りながら当該係合爪部２５が係合穴部１６からＺ軸方向に離間移動し、係合爪部２５および係合穴部１６の係合が解除される。このため、吊下体２０は、過度に大きな引き抜き力が加えられることでベース体１０から外れる。 In the hanging tool 1 described above, when a large pulling force (force opposite to the insertion direction A) is applied to the hook portion 22, the elastic deformation portion 226 of the vertical piece portion 221 is elastically deformed and suspended. The damage of the lower body 20 is suppressed. When an excessively large pulling force is applied to the hook portion 22, the engaging claw portion 25 is engaged while the inclined surface 253 of the engaging claw portion 25 slides with respect to the peripheral surface 161 of the engaging hole portion 16. The engagement claw part 25 and the engagement hole part 16 are disengaged by moving away from the joint hole part 16 in the Z-axis direction. For this reason, the suspended body 20 is detached from the base body 10 by applying an excessively large pulling force.

第１実施形態に係る吊下具１によれば、以下の作用効果を発揮できる。
（１）本実施形態では、吊下具１は、被差込部１５が形成されたベース体１０と、被差込部１５に差し込まれる差込部２１および差込部２１につながったフック部２２を有した吊下体２０とを備えており、被差込部１５および差込部２１のうちのいずれか一方には、Ｚ軸方向に窪んだ周面円弧状の係合穴部１６，１６Ａが形成されており、被差込部１５および差込部２１のうちのいずれか他方には、係合穴部１６に係合する周面円弧状の係合爪部２５がＺ軸方向に突出して形成されており、係合爪部２５の周面２５１のうち係合穴部１６の周面１６１に圧接する面領域は、差込方向Ａに対して傾斜していると共に、係合穴部１６に対してＺ軸方向に離間する移動を係合爪部２５に生じさせる構成とされていることを特徴とする。
上記構成を有するため、互いに係合する係合穴部１６および係合爪部２５の周面１６１，２５１が円弧状に形成されているので、差込部２１のＺ軸方向に沿った軸心周りで吊下体２０をＲ方向に回動させることができ、首振り可能な吊下具１を構成できる。その上、例えばフック部２２に過度な引き抜き力が加えられた場合には、吊下体２０がベース体１０に対してどの回動角度にあっても、前述した面領域が係合穴部１６の周面１６１に圧接することで、Ｚ軸方向において係合爪部２５が係合穴部１６から離間移動して係合が解除され、吊下体２０をベース体１０から外すことができ、これにより、吊下具１に過度な力が加えられることを防止できる。
（２）フック部２２は、縦片部２２１と、縦片部２２１に連続した底片部２２２と、底片部２２２に連続した立上げ片部２２３とを有しており、縦片部２２１および立上げ片部２２３の間に形成されたフック開口２２４には、当該フック開口２２４を開閉可能なバネ部材２６が配置されており、縦片部２２１には、Ｙ幅方向に沿ったスリット２２５が形成されている。
このため、縦片部２２１のうちスリット２２５が形成された部分の厚さ寸法が小さくなるので、例えばフック部２２に過度な引き下げ力が加えられた場合に縦片部２２１に厚さ方向の弾性変形を生じさせることができ、この弾性変形によって吊下体２０が破損することを抑制できる。
（３）差込部２１には、係合爪部２５がＺ軸方向に進退可能な孔部２１１が形成されている。
このため、係合爪部２５を孔部２１１に入り込ませることができるので、差込部２１の厚さ寸法を小さくでき、吊下具１の薄型化を図ることができる。
（４）吊下具１は、ベース体１０および吊下体２０の二部材で構成され、吊下体２０をベース体１０に差し込むだけでベース体１０および吊下体２０を連結できるので、吊下具１の組み立てに手間がかからずに簡単に行うことができる。
また、万が一、ベース体１０や吊下体２０が破損しても、対応部品だけ交換することができる。

(1) In the present embodiment, the hanging tool 1 includes a base body 10 on which the inserted portion 15 is formed, an insertion portion 21 that is inserted into the inserted portion 15, and a hook portion that is connected to the insertion portion 21. The suspended body 20 having 22 is provided, and either one of the insertion portion 15 and the insertion portion 21 has engagement holes 16 and 16A having circular arc surfaces that are recessed in the Z-axis direction. An engagement claw portion 25 having a circular arc surface that engages with the engagement hole portion 16 projects in the Z-axis direction on either the inserted portion 15 or the insertion portion 21. The surface area of the peripheral surface 251 of the engaging claw portion 25 that presses against the peripheral surface 161 of the engaging hole portion 16 is inclined with respect to the insertion direction A, and the engaging hole portion 16, the engaging claw portion 25 is caused to move away from the engaging claw 16 in the Z-axis direction.
Since the engaging hole portion 16 and the peripheral surfaces 161 and 251 of the engaging claw portion 25 that are engaged with each other are formed in an arc shape because of the above configuration, the axial center of the insertion portion 21 along the Z-axis direction. The suspension body 20 can be rotated in the R direction around the suspension body 1, and the suspension tool 1 that can be swung can be configured. In addition, for example, when an excessive pulling force is applied to the hook portion 22, the above-described surface region of the engagement hole portion 16 is formed regardless of the rotation angle of the suspension body 20 with respect to the base body 10. By press-contacting with the peripheral surface 161, the engagement claw portion 25 moves away from the engagement hole portion 16 in the Z-axis direction, the engagement is released, and the suspended body 20 can be detached from the base body 10, thereby It is possible to prevent an excessive force from being applied to the hanging tool 1.
(2) The hook portion 22 includes a vertical piece 221, a bottom piece 222 continuous to the vertical piece 221, and a rising piece 223 continuous to the bottom piece 222. A spring member 26 capable of opening and closing the hook opening 224 is disposed in the hook opening 224 formed between the raised pieces 223, and a slit 225 along the Y width direction is formed in the vertical piece 221. Has been.
For this reason, since the thickness dimension of the part in which the slit 225 is formed becomes small among the vertical piece parts 221, for example, when an excessive pulling force is applied to the hook part 22, the elasticity in the thickness direction is applied to the vertical piece part 221. It is possible to cause deformation, and it is possible to prevent the suspended body 20 from being damaged by this elastic deformation.
(3) The insertion portion 21 is formed with a hole 211 through which the engagement claw portion 25 can advance and retract in the Z-axis direction.
For this reason, since the engagement nail | claw part 25 can be penetrated into the hole 211, the thickness dimension of the insertion part 21 can be made small and the suspension tool 1 can be made thin.
(4) The hanging tool 1 is composed of two members, the base body 10 and the hanging body 20, and the base body 10 and the hanging body 20 can be connected by simply inserting the hanging body 20 into the base body 10. It can be easily done without the hassle of assembling.
Moreover, even if the base body 10 and the suspended body 20 are damaged, only corresponding parts can be replaced.
Furthermore, since it is not necessary to connect the base body 10 and the suspension body 20 in advance in a factory or the like, the suspension tool 1 can be easily assembled on the user side even if the manufacturers of the base body 10 and the suspension body 20 are different. be able to.

Hereinafter, a fourth embodiment of the present invention will be described with reference to the drawings.
In FIG. 7, the suspending tool 1D according to the second embodiment is configured in substantially the same manner as the suspending tool 1 described above, but an engagement hole 16D is formed in the insertion portion 21 and the engagement tool 16D is engaged. The configuration differs from the hanging tool 1 in that the claw portion 25D is formed on the base body 10.

係合穴部１６Ｄの周面１６１Ｄは円弧状に形成されており、周面１６１Ｄのうちフック部２２側から上方に離間した側に位置する面領域、すなわち、周面１６１Ｄのうち係合爪部２５Ｄの周面２５１Ｄに圧接する面領域は、吊下体２０のベース体１０に対する差込方向Ａに対して傾斜しており、第４実施形態では、係合爪部２５Ｄおよび係合穴部１６Ｄの係合状態で係合穴部１６Ｄ側から係合爪部２５Ｄ側に向かうに連れて斜め上に傾斜した傾斜面１６３Ｄによって形成されている。 The peripheral surface 161D of the engagement hole portion 16D is formed in an arc shape, and is a surface region located on the side of the peripheral surface 161D that is spaced upward from the hook portion 22 side, that is, the engagement claw portion of the peripheral surface 161D. The surface area that is in pressure contact with the peripheral surface 251D of 25D is inclined with respect to the insertion direction A with respect to the base body 10 of the suspended body 20, and in the fourth embodiment, the engagement claw portion 25D and the engagement hole portion 16D In the engaged state, it is formed by an inclined surface 163D that is inclined obliquely upward as it goes from the engagement hole portion 16D side to the engagement claw portion 25D side.

係合爪部２５Ｄの周面２５１Ｄは円弧状に形成されており、周面２５１Ｄのうち係合穴部１６の周面１６１Ｄ（ここでは傾斜面１６３Ｄ）に圧接する面領域（周面２５１Ｄの上部領域）は、差込方向Ａに対して傾斜しており、第４実施形態では、係合爪部２５Ｄおよび係合穴部１６Ｄの係合状態で係合穴部１６Ｄ側か係合爪部２５Ｄ側に向かうに連れて斜め上に傾斜した傾斜面２５３Ｄによって形成されている。 The peripheral surface 251D of the engaging claw portion 25D is formed in an arc shape, and a surface region (upper portion of the peripheral surface 251D) that presses the peripheral surface 161D (here, the inclined surface 163D) of the engaging hole portion 16 in the peripheral surface 251D. The region is inclined with respect to the insertion direction A. In the fourth embodiment, the engagement claw portion 25D and the engagement claw portion 25D are engaged with the engagement claw portion 25D and the engagement claw portion 16D. It is formed by the inclined surface 253D inclined obliquely upward as it goes to the side.

このように構成されているので、吊下体２０に過度の引き抜き力が加えられた場合には、係合爪部２５Ｄの傾斜面２５３Ｄが係合穴部１６Ｄの傾斜面１６３Ｄに対して滑りながら当該係合爪部２５Ｄが係合穴部１６ＤからＺ軸方向に離間移動し、係合爪部２５Ｄおよび係合穴部１６Ｄの係合が解除される。このため、吊下体２０は、過度に大きな引き抜き力が加えられることでベース体１０から外れる。 With this configuration, when an excessive pulling force is applied to the suspended body 20, the inclined surface 253D of the engaging claw portion 25D slides relative to the inclined surface 163D of the engaging hole portion 16D. The engagement claw portion 25D moves away from the engagement hole portion 16D in the Z-axis direction, and the engagement between the engagement claw portion 25D and the engagement hole portion 16D is released. For this reason, the suspended body 20 is detached from the base body 10 by applying an excessively large pulling force.
