本発明は、バーロック装置に関する。 The present invention relates to a bar lock device.

従来、回転自在に連結された複数のロッドと、複数のロッドの一端に設けられた錠装置本体と、複数のロッドの他端に設けられ錠装置本体に対して着脱可能な着脱竿とを備えたバーロック装置が知られている（特許文献１参照）。このバーロック装置は、各ロッドが第１芯材と樹脂被覆とを備え、第１芯材がハンドハクソー等の切断アタックに耐え得る硬度を有したもので構成されている。 Conventionally, a plurality of rods rotatably connected, a locking device main body provided at one end of the plurality of rods, and a detachable rod provided at the other end of the plurality of rods and detachable from the locking device main body are provided. A bar lock device is known (see Patent Document 1). In this bar lock device, each rod is provided with a first core material and a resin coating, and the first core material is configured to have hardness enough to withstand a cutting attack such as a hand hack saw.

特開平８−１２８２４５号公報Japanese Unexamined Patent Publication No. 8-128245

しかし、特許文献１に記載のバーロック装置は、第１芯材が切断アタックに耐え得る硬度を有したものであることから、重量も大きくなる傾向にあり、軽量化が困難であるものであった。そこで、第１芯材の素材を比較的軽いものにした場合には、切断アタックに対して充分な防盗性を有したものでなくなってしまう可能性がある。 However, since the bar lock device described in Patent Document 1 has a hardness that allows the first core material to withstand a cutting attack, the weight tends to be large, and it is difficult to reduce the weight. It was. Therefore, if the material of the first core material is made relatively light, there is a possibility that the material does not have sufficient anti-theft property against cutting attack.

本発明は、このような従来の課題を解決するためになされたものであり、その目的とするところは、重量の増加を抑えつつも防盗性の低下を抑制することができるバーロック装置を提供することにある。 The present invention has been made to solve such a conventional problem, and an object of the present invention is to provide a bar lock device capable of suppressing a decrease in anti-theft property while suppressing an increase in weight. To do.

上記目的を達成するため、本発明に係るバーロック装置は、チェーン状拘束体の閉ループにより施錠対象を拘束するものであり、チェーン状拘束体を構成する複数のロッドの少なくとも１つは第１芯材と第１芯材の周囲を覆う第２芯材とを有し、第２芯材は第１芯材よりも硬度が高い素材で形成され、第１芯材は第２芯材よりも比重の小さい素材で形成されている。 In order to achieve the above object, the bar lock device according to the present invention restrains the locked object by a closed loop of the chain-shaped restraint, and at least one of the plurality of rods constituting the chain-shaped restraint is the first core. It has a material and a second core material that covers the periphery of the first core material, the second core material is formed of a material having a higher hardness than the first core material, and the first core material has a specific gravity higher than that of the second core material. It is made of a small material.

本発明に係るバーロック装置によれば、第１芯材と第２芯材とを有して構成されるロッドに対する切断アタックについては硬度が高い第２芯材によって耐え得るようにできると共に、内部の第１芯材については比重の小さい素材で形成されているため、重量の増加を抑えることができる。従って、重量の増加を抑えつつも防盗性の低下を抑制することができる。 According to the bar lock device according to the present invention, the cutting attack on the rod having the first core material and the second core material can be made to withstand by the second core material having high hardness, and the inside can be withstood. Since the first core material of No. 1 is made of a material having a small specific gravity, an increase in weight can be suppressed. Therefore, it is possible to suppress a decrease in anti-theft property while suppressing an increase in weight.

本発明によれば、重量の増加を抑えつつも防盗性の低下を抑制することができるバーロック装置を提供することができる。 According to the present invention, it is possible to provide a bar lock device capable of suppressing a decrease in anti-theft property while suppressing an increase in weight.

図１は、本実施形態に係るバーロック装置の詳細を示す全体構成図である。図１に示すように、本実施形態に係るバーロック装置１は、チェーン状拘束体１０と、錠装置本体２０とを備えている。このバーロック装置１は、チェーン状拘束体１０の両端部を錠装置本体２０に着脱可能に構成し、両端部の錠装置本体２０への装着時において形成されるチェーン状拘束体１０の閉ループにより施錠対象Ａを拘束するものである。なお、バーロック装置１は、チェーン状拘束体１０の一端部を錠装置本体２０に着脱可能に構成し、他端部を錠装置本体２０に固着（着脱不可に固定）したものであってもよいが、以下の実施形態ではチェーン状拘束体１０の両端部を錠装置本体２０に着脱可能にしたバーロック装置１を例に説明する。 FIG. 1 is an overall configuration diagram showing details of the bar lock device according to the present embodiment. As shown in FIG. 1, the bar lock device 1 according to the present embodiment includes a chain-shaped restraint body 10 and a lock device main body 20. In this bar lock device 1, both ends of the chain-shaped restraint body 10 are detachably attached to and detached from the lock device main body 20, and both ends are formed by a closed loop of the chain-shaped restraint body 10 when attached to the lock device main body 20. It restrains the lock target A. Even if the bar lock device 1 is configured such that one end of the chain-shaped restraint 10 can be attached to and detached from the lock device main body 20 and the other end thereof is fixed to the lock device main body 20 (fixed so as not to be removable). However, in the following embodiment, the bar lock device 1 in which both ends of the chain-shaped restraint body 10 can be attached to and detached from the lock device main body 20 will be described as an example.

図２は、図１に示したチェーン状拘束体１０の上面図であり、図３は、図２に示したチェーン状拘束体１０のＩＩＩ−ＩＩＩ断面図である。 FIG. 2 is a top view of the chain-shaped restraint body 10 shown in FIG. 1, and FIG. 3 is a sectional view taken along line III-III of the chain-shaped restraint body 10 shown in FIG.

図１及び図２に示すように、チェーン状拘束体１０は、複数のロッド１１を回転自在に連結して形成されたものである。本実施形態においてチェーン状拘束体１０は例えば１０本のロッド１１を連結して構成されている。複数のロッド１１は、錠連結ロッド１２と、中間ロッド（多層芯材ロッド）１３とからなる。錠連結ロッド１２と中間ロッド１３とは、それぞれが直線状に形成され、錠連結ロッド１２が中間ロッド１３よりも短寸に形成されている。 As shown in FIGS. 1 and 2, the chain-shaped restraint body 10 is formed by rotatably connecting a plurality of rods 11. In the present embodiment, the chain-shaped restraint body 10 is configured by connecting, for example, 10 rods 11. The plurality of rods 11 include a lock connecting rod 12 and an intermediate rod (multilayer core material rod) 13. The lock connecting rod 12 and the intermediate rod 13 are each formed in a straight line, and the lock connecting rod 12 is formed to be shorter than the intermediate rod 13.

図１〜図３に示すように、錠連結ロッド１２は、チェーン状拘束体１０の両端部に設けられ、錠装置本体２０に着脱される着脱竿１２ａを備えている。着脱竿１２ａは、先端側の係止部１２ｂと根元側の基部１２ｃとを有している。係止部１２ｂは、基部１２ｃよりも縮径された凹部を有しており、この凹部が錠装置本体２０のロック片（後述する図６の符号２３参照）に引っ掛かることにより、装着状態となる。 As shown in FIGS. 1 to 3, the lock connecting rod 12 is provided at both ends of the chain-shaped restraint body 10 and includes a detachable rod 12a that is attached to and detached from the lock device main body 20. The detachable rod 12a has a locking portion 12b on the tip side and a base portion 12c on the root side. The locking portion 12b has a recess whose diameter is smaller than that of the base portion 12c, and when this recess is caught by a lock piece (see reference numeral 23 in FIG. 6 to be described later) of the locking device main body 20, the locking portion 12b is in a mounted state. ..

図３に示すように、錠連結ロッド１２のうち、着脱竿１２ａが設けられる側と反対側の端部は、中間ロッド１３に連結するための連結開口部（開口部）１４が形成されている。また、中間ロッド１３は、錠連結ロッド１２又は他の中間ロッド１３に連結するための連結開口部１４が両端部に形成されている。 As shown in FIG. 3, of the lock connecting rod 12, a connecting opening (opening) 14 for connecting to the intermediate rod 13 is formed at the end on the side opposite to the side where the attachment / detachment rod 12a is provided. .. Further, the intermediate rod 13 is formed with connecting openings 14 at both ends for connecting to the lock connecting rod 12 or another intermediate rod 13.

錠連結ロッド１２及び中間ロッド１３は、連結開口部１４が接続対象となる錠連結ロッド１２又は中間ロッド１３の連結開口部１４と連通するように配置され、この連通状態においてヒンジ部材１５が連結開口部１４に挿入固定されることで、接続対象のロッド１１と連結される。このような連結状態において、各ロッド１１は、ヒンジ部材１５を回転軸として回転自在とされる。なお、ここでの回転角は、３６０°であってもよいし、それ未満であってもよい。 The lock connecting rod 12 and the intermediate rod 13 are arranged so that the connecting opening 14 communicates with the locking connecting rod 12 to be connected or the connecting opening 14 of the intermediate rod 13, and the hinge member 15 opens the connecting opening in this communication state. By being inserted and fixed to the portion 14, it is connected to the rod 11 to be connected. In such a connected state, each rod 11 is rotatable around the hinge member 15 as a rotation axis. The rotation angle here may be 360 ° or less.

また、図３に示すように、中間ロッド１３（複数のロッド１１の少なくとも１つの一例）は、それぞれが金属製の第１芯材１６と、第１芯材１６を覆う金属性の第２芯材１７と、第２芯材１７を覆う樹脂製の被覆材１８とを備えている。 Further, as shown in FIG. 3, the intermediate rod 13 (at least one example of the plurality of rods 11) has a first core material 16 made of metal and a second metal core covering the first core material 16, respectively. A material 17 and a resin covering material 18 that covers the second core material 17 are provided.

図４は、図３に示した第１芯材１６と第２芯材１７とを示す斜視図であり、（ａ）は分解斜視を示し、（ｂ）は組み付け状態を示している。図４（ａ）に示す第１芯材１６は、第２芯材１７よりも比重が小さい素材（好ましくは第２芯材１７よりも靭性が高い素材）で形成された略四角柱となる部材であって、例えばアルミニウム等の軽量の金属から構成されている。第２芯材１７は、第１芯材１６よりも硬度が高い素材で形成された四角筒状部材であって、例えば熱処理により硬度を向上させた鋼材によって構成されている。このような第２芯材１７は、ＨＲＣ硬度が少なくとも１０以上であり、好ましくは２０以上とされている。第１芯材１６は、図４（ｂ）に示すように第２芯材１７内に挿入配置されるようになっている。 4A and 4B are perspective views showing the first core material 16 and the second core material 17 shown in FIG. 3, where FIG. 4A shows an exploded perspective view and FIG. 4B shows an assembled state. The first core material 16 shown in FIG. 4A is a member formed of a material having a specific gravity smaller than that of the second core material 17 (preferably a material having a higher toughness than the second core material 17) and forming a substantially quadrangular prism. It is made of a lightweight metal such as aluminum. The second core material 17 is a square tubular member made of a material having a hardness higher than that of the first core material 16, and is made of, for example, a steel material whose hardness has been improved by heat treatment. Such a second core material 17 has an HRC hardness of at least 10 or more, preferably 20 or more. As shown in FIG. 4B, the first core material 16 is inserted and arranged in the second core material 17.

さらに、第１芯材１６には中間ロッド１３の連結開口部１４の一部を構成する第１芯材開口部１４ａが形成されている。また、第２芯材１７には中間ロッド１３の連結開口部１４の一部を構成する第２芯材開口部１４ｂが形成されている。第１芯材１６と第２芯材１７とが組み付けられた場合、第１芯材開口部１４ａと第２芯材開口部１４ｂとは連通する。 Further, the first core material 16 is formed with a first core material opening 14a forming a part of the connecting opening 14 of the intermediate rod 13. Further, the second core material 17 is formed with a second core material opening 14b that forms a part of the connecting opening 14 of the intermediate rod 13. When the first core material 16 and the second core material 17 are assembled, the first core material opening 14a and the second core material opening 14b communicate with each other.

中間ロッド１３は、第１芯材１６と第２芯材１７とを組み付けて得られた一体物が被覆材１８内にインサート成型されて製造される。なお、本実施形態において中間ロッド１３は、インサート成型によって第１及び第２芯材１６，１７が被覆材１８に内包されているが、特にこれに限らず、被覆材１８が樹脂製のチューブによって構成され、このチューブ内に第１及び第２芯材１６，１７が内包される構成であってもよい。加えて、第１芯材１６に対する第２芯材１７の位置規制はインサート成型に限らず加締めやピン止めで行われてもよい。 The intermediate rod 13 is manufactured by insert-molding an integral product obtained by assembling the first core material 16 and the second core material 17 into the covering material 18. In the present embodiment, the intermediate rod 13 includes the first and second core materials 16 and 17 in the coating material 18 by insert molding, but the present invention is not particularly limited to this, and the coating material 18 is made of a resin tube. It may be configured so that the first and second core members 16 and 17 are included in the tube. In addition, the position regulation of the second core material 17 with respect to the first core material 16 is not limited to insert molding, and may be performed by crimping or pinning.

さらに、本実施形態において第２芯材１７は１つの筒状部材によって形成されているが、これに限らず、２つ以上の部材によって構成され、２つ以上の部材が組み付けられた結果、筒状となるものであってもよい。さらに、第２芯材１７は、第２芯材開口部１４ｂ以外の箇所に適宜開口が設けられて例えば網状とされていてもよい。加えて、第１芯材１６は四角柱に限らず丸柱や三角柱等他の形状とされていてもよい。同様に、第２芯材１７や被覆材１８についても他の形状とされていてもよい。 Further, in the present embodiment, the second core member 17 is formed of one tubular member, but is not limited to this, and is composed of two or more members, and as a result of assembling the two or more members, the cylinder It may be in the form of a shape. Further, the second core material 17 may be formed in a net shape, for example, by appropriately providing an opening at a position other than the second core material opening 14b. In addition, the first core material 16 is not limited to a square prism, and may have other shapes such as a round prism or a triangular prism. Similarly, the second core material 17 and the covering material 18 may have other shapes.

一方、錠連結ロッド１２は、図３に示すように鋼材１９と被覆材１８とを備えて構成されており、第１芯材１６及び第２芯材１７を備えない構成となっている。鋼材１９は、第２芯材１７と同程度の硬度を有するものであって、着脱竿１２ａと一体となっている。なお、鋼材１９のうち着脱竿１２ａと反対側端部には、連結開口部１４の一部を構成する開口部が形成されている。 On the other hand, the lock connecting rod 12 is configured to include the steel material 19 and the covering material 18 as shown in FIG. 3, and is configured not to include the first core material 16 and the second core material 17. The steel material 19 has the same hardness as the second core material 17, and is integrated with the detachable rod 12a. An opening forming a part of the connecting opening 14 is formed at the end of the steel material 19 opposite to the detachable rod 12a.

図５は、図３に示したヒンジ部材１５付近の一部拡大図である。図３及び図５に示すように、ヒンジ部材１５は、例えば焼き入れされることなく靭性が比較的高い金属部材によって構成され、圧入ピン１５ａと、ピン受部１５ｂとを備えて構成されている。圧入ピン１５ａは、チェーン状拘束体１０（図３参照）の一側から連結開口部１４に挿入されるようになっている。ピン受部１５ｂは、チェーン状拘束体１０の他側から連結開口部１４に挿入されるようになっている。なお、ヒンジ部材１５は焼き入れされて硬度が高められた金属部材によって構成されてもよい。 FIG. 5 is a partially enlarged view of the vicinity of the hinge member 15 shown in FIG. As shown in FIGS. 3 and 5, the hinge member 15 is made of, for example, a metal member having relatively high toughness without being hardened, and includes a press-fit pin 15a and a pin receiving portion 15b. .. The press-fit pin 15a is inserted into the connecting opening 14 from one side of the chain-shaped restraint body 10 (see FIG. 3). The pin receiving portion 15b is inserted into the connecting opening 14 from the other side of the chain-shaped restraint body 10. The hinge member 15 may be made of a metal member that has been hardened to increase its hardness.

ピン受部１５ｂには、先端側に凹部１５ｄ（図５参照）が形成されている。この凹部１５ｄの内径は圧入ピン１５ａの先端径と略一致している。このため、圧入ピン１５ａとピン受部１５ｂとを連結開口部１４の反対側から互いに挿入すると、圧入ピン１５ａの先端が凹部１５ｄに圧入される。この圧入によってヒンジ部材１５が連結開口部１４において挿入固定される。 The pin receiving portion 15b is formed with a recess 15d (see FIG. 5) on the tip end side. The inner diameter of the recess 15d is substantially the same as the tip diameter of the press-fit pin 15a. Therefore, when the press-fitting pin 15a and the pin receiving portion 15b are inserted into each other from the opposite side of the connecting opening 14, the tip of the press-fitting pin 15a is press-fitted into the recess 15d. By this press fitting, the hinge member 15 is inserted and fixed in the connecting opening 14.

さらに、圧入ピン１５ａ及びピン受部１５ｂは、それぞれ後端側に径方向へ広がるフランジ１５ｃを有している。フランジ１５ｃは、連結開口部１４よりも大径に形成されている。よって、ヒンジ部材１５の挿入固定によってロッド１１同士が連結されることとなる。 Further, the press-fit pin 15a and the pin receiving portion 15b each have a flange 15c extending in the radial direction toward the rear end side. The flange 15c is formed to have a diameter larger than that of the connecting opening 14. Therefore, the rods 11 are connected to each other by inserting and fixing the hinge member 15.

ここで、図５に示すように、第２芯材開口部１４ｂの内径φ２は第１芯材開口部１４ａの内径φ１よりも大きくされている。よって、第２芯材開口部１４ｂは、第１芯材開口部１４ａよりもヒンジ部材１５から離間した状態となっている。 Here, as shown in FIG. 5, the inner diameter φ2 of the second core material opening 14b is larger than the inner diameter φ1 of the first core material opening 14a. Therefore, the second core material opening 14b is in a state of being separated from the hinge member 15 by the first core material opening 14a.

図６は、図１に示した錠装置本体２０の内部状態を示す側面図である。図６に示すように、錠装置本体２０は、充分な破壊強度を有して各部品を収納するケーシング２１と、ケーシング２１の内部に設けられるシリンダ錠２２及びロック片２３等を備えている。 FIG. 6 is a side view showing the internal state of the lock device main body 20 shown in FIG. As shown in FIG. 6, the lock device main body 20 includes a casing 21 that has sufficient breaking strength to store each component, a cylinder lock 22 provided inside the casing 21, a lock piece 23, and the like.

ケーシング２１には、着脱竿１２ａが挿入される２つの挿入穴２１ａが形成されている。２つの挿入穴２１ａには、ロック片２３が進退自在に設けられている。ロック片２３は、回転軸２３ａ回りに回転可能な断面半円形状の柱体である。このロック片２３は、半円の角部となる部位が係止片２３ｂとして機能するようになっている。 The casing 21 is formed with two insertion holes 21a into which the attachment / detachment rod 12a is inserted. Lock pieces 23 are provided in the two insertion holes 21a so as to be able to move forward and backward. The lock piece 23 is a pillar body having a semicircular cross section that can rotate around the rotation shaft 23a. In this lock piece 23, a portion that becomes a corner of a semicircle functions as a locking piece 23b.

ロック片２３には、係止片２３ｂが進入状態となるように付勢するトーションスプリング２４が設けられている。着脱竿１２ａが挿入穴２１ａに挿入される場合、まず着脱竿１２ａの先端がロック片２３の係止片２３ｂに当接する。この当接状態において更に着脱竿１２ａが挿入されると、着脱竿１２ａがトーションスプリング２４の付勢力に抗して係止片２３ｂを挿入穴２１ａから退避させる。着脱竿１２ａの挿入完了時には、トーションスプリング２４の付勢力により係止片２３ｂが進入状態に復帰して、着脱竿１２ａの係止部１２ｂとなる凹部に嵌り込むようになる。 The lock piece 23 is provided with a torsion spring 24 that urges the locking piece 23b to enter the approaching state. When the attachment / detachment rod 12a is inserted into the insertion hole 21a, the tip of the attachment / detachment rod 12a first comes into contact with the locking piece 23b of the lock piece 23. When the detachable rod 12a is further inserted in this contact state, the detachable rod 12a retracts the locking piece 23b from the insertion hole 21a against the urging force of the torsion spring 24. When the insertion of the attachment / detachment rod 12a is completed, the locking piece 23b returns to the approached state by the urging force of the torsion spring 24 and fits into the recess serving as the locking portion 12b of the attachment / detachment rod 12a.

シリンダ錠２２は、正規な機械式キーＫを挿入したときに回転操作が可能なプラグ２２ａを備えている。プラグ２２ａの終端にはストッパブロック２５が連結されている。また、ロック片２３は、半円の他の角部となる部位にストッパ突起２３ｃを有している。錠装置本体２０の施錠状態においてストッパブロック２５は、ロック片２３のストッパ突起２３ｃに接触しており、着脱竿１２ａが取り外される方向へのロック片２３の回動を規制するようになっている。 The cylinder lock 22 includes a plug 22a that can be rotated when a regular mechanical key K is inserted. A stopper block 25 is connected to the end of the plug 22a. Further, the lock piece 23 has a stopper protrusion 23c at a portion serving as another corner of the semicircle. In the locked state of the lock device main body 20, the stopper block 25 is in contact with the stopper protrusion 23c of the lock piece 23, and restricts the rotation of the lock piece 23 in the direction in which the attachment / detachment rod 12a is removed.

一方、シリンダ錠２２に対して正規な機械式キーＫを挿入し、回転操作を行った場合、ストッパブロック２５は、着脱竿１２ａが取り外される方向へのロック片２３の回動を許容する状態となる。 On the other hand, when a regular mechanical key K is inserted into the cylinder lock 22 and a rotation operation is performed, the stopper block 25 is in a state of allowing the lock piece 23 to rotate in the direction in which the attachment / detachment rod 12a is removed.

次に、本実施形態に係るバーロック装置１の重量及び防盗性について説明する。まず、本実施形態において中間ロッド１３は、第１芯材１６よりも硬度が高い第２芯材１７の内部に、第２芯材１７よりも比重が小さい第１芯材１６を備えている。このため、芯材の全体を第２芯材１７と同じ素材で作成したものと比較して、本実施形態に係る中間ロッド１３は第１芯材１６による軽量化が図られている。なお、本実施形態において第２芯材１７は軽量化の観点から肉薄であることが好ましく、第２芯材１７の各周壁（第１芯材１６を覆うそれぞれの壁）は少なくとも第１芯材１６よりも肉薄となっていることが好ましい。 Next, the weight and theft protection of the bar lock device 1 according to the present embodiment will be described. First, in the present embodiment, the intermediate rod 13 includes a first core material 16 having a specific gravity smaller than that of the second core material 17 inside the second core material 17 having a hardness higher than that of the first core material 16. Therefore, the weight of the intermediate rod 13 according to the present embodiment is reduced by the first core material 16 as compared with the case where the entire core material is made of the same material as the second core material 17. In the present embodiment, the second core material 17 is preferably thin from the viewpoint of weight reduction, and each peripheral wall of the second core material 17 (each wall covering the first core material 16) is at least the first core material. It is preferably thinner than 16.

また、中間ロッド１３に対してハンドハクソー等による切断アタックがあったとする。この場合、切断刃が被覆材１８を切り裂くこととなるが第２芯材１７については切り裂くことができない。よって、切断刃は第２芯材１７によって食い止められることとなる。この結果、中間ロッド１３自体の切断は防止されることとなる。なお、錠連結ロッド１２に対して切断アタックがあった場合には、従来と同様に鋼材１９によって切断刃が食い止められて錠連結ロッド１２の切断が防止されることとなる。 Further, it is assumed that the intermediate rod 13 has a cutting attack by a hand hook saw or the like. In this case, the cutting blade cuts the covering material 18, but the second core material 17 cannot be cut. Therefore, the cutting blade is stopped by the second core material 17. As a result, cutting of the intermediate rod 13 itself is prevented. When there is a cutting attack on the lock connecting rod 12, the cutting blade is stopped by the steel material 19 as in the conventional case, and the locking of the lock connecting rod 12 is prevented.

さらに、中間ロッド１３を接続するヒンジ部材１５に対してハンマー等による衝撃が加わったとする。この場合、ヒンジ部材１５に加わった衝撃は、第１芯材１６まで伝達される。ここで、第２芯材１７は、第２芯材開口部１４ｂが第１芯材開口部１４ａよりも内径が大きくされてヒンジ部材１５から離間していることから、衝撃は第２芯材１７に伝達し難くなる。特に、第１芯材１６は第２芯材１７よりも肉厚とされていることから、肉厚の第１芯材１６に衝撃が伝達され易くなる。加えて、第１芯材１６が第２芯材１７よりも靭性が高い場合には、高い靭性によって衝撃を吸収するような作用をもたらすこととなる。 Further, it is assumed that an impact by a hammer or the like is applied to the hinge member 15 connecting the intermediate rod 13. In this case, the impact applied to the hinge member 15 is transmitted to the first core member 16. Here, in the second core material 17, the impact is caused by the second core material 17 because the second core material opening 14b has an inner diameter larger than that of the first core material opening 14a and is separated from the hinge member 15. It becomes difficult to convey to. In particular, since the first core material 16 is thicker than the second core material 17, the impact is easily transmitted to the thick first core material 16. In addition, when the first core material 16 has a higher toughness than the second core material 17, the high toughness brings about an action of absorbing an impact.

なお、ヒンジ部材１５への衝撃に限らず、例えば２つの中間ロッド１３同士を捻じったり引っ張ったりした場合についても、第２芯材開口部１４ｂの内径が大きくされていることから、捻じりや引っ張り時に力はまず第１芯材１６に加わって第２芯材１７に力が加わり難くなる。 Not only the impact on the hinge member 15, but also when the two intermediate rods 13 are twisted or pulled, for example, the inner diameter of the second core material opening 14b is increased, so that the second core material opening 14b is twisted or pulled. Sometimes the force is first applied to the first core material 16 and it becomes difficult for the force to be applied to the second core material 17.

加えて、ドライバー等の先端が鋭利な道具を用いて、第２芯材開口部１４ｂから第１芯材１６に直接アタックしようとしても、フランジ１５ｃが第２芯材開口部１４ｂを覆うことから、第１芯材１６への直接アタックも防止される。 In addition, even if an attempt is made to directly attack the first core material 16 from the second core material opening 14b using a tool with a sharp tip such as a screwdriver, the flange 15c covers the second core material opening 14b. A direct attack on the first core material 16 is also prevented.

このようにして、本実施形態に係るバーロック装置１によれば、中間ロッド１３は第１芯材１６と第１芯材１６を覆う金属性の第２芯材１７とを有し、第２芯材１７は第１芯材１６よりも硬度が高い素材で形成され、第１芯材１６は第２芯材１７よりも比重の小さい素材で形成されている。このため、第１芯材１６と第２芯材１７とを有して構成される中間ロッド１３については、切断アタックに対して硬度が高い第２芯材１７によって耐え得るようにできると共に、内部の第１芯材１６については比重の小さい素材で形成されているため、重量の増加を抑えることができる。従って、重量の増加を抑えつつも防盗性の低下を抑制することができる。 In this way, according to the bar lock device 1 according to the present embodiment, the intermediate rod 13 has the first core material 16 and the metallic second core material 17 that covers the first core material 16, and is the second. The core material 17 is formed of a material having a hardness higher than that of the first core material 16, and the first core material 16 is formed of a material having a specific gravity smaller than that of the second core material 17. Therefore, the intermediate rod 13 having the first core material 16 and the second core material 17 can be made to withstand the cutting attack by the second core material 17 having a high hardness, and the inside thereof. Since the first core material 16 of the above is made of a material having a small specific gravity, an increase in weight can be suppressed. Therefore, it is possible to suppress a decrease in anti-theft property while suppressing an increase in weight.

また、第２芯材開口部１４ｂは、第１芯材開口部１４ａよりも内径が大きくされて挿入固定されたヒンジ部材１５から離間しているため、例えばヒンジ部材１５に衝撃が加わった場合に、その衝撃を第２芯材１７に伝達させ難くすることができる。 Further, since the second core material opening 14b has an inner diameter larger than that of the first core material opening 14a and is separated from the hinge member 15 which is inserted and fixed, for example, when an impact is applied to the hinge member 15. , It is possible to make it difficult to transmit the impact to the second core material 17.

また、ヒンジ部材１５は第２芯材開口部１４ｂを覆うフランジ１５ｃを有しているため、外部から直接第１芯材１６に対してアタックされ難くして、破壊されてしまう可能性を低減することができる。加えて、ドライバー等を第２芯材開口部１４ｂに差し込んだこじりについても防止することができる。 Further, since the hinge member 15 has a flange 15c that covers the opening 14b of the second core material, it is difficult for the hinge member 15 to be directly attacked by the first core material 16 from the outside, and the possibility of being destroyed is reduced. be able to. In addition, it is possible to prevent prying when a screwdriver or the like is inserted into the second core material opening 14b.
