Description

この発明は、錠箱に係り、特に、シリンダ錠を直接錠箱に取付けるようにし、破錠に対する抵抗力を高めた錠箱に関する。   The present invention relates to a lock box, and more particularly, to a lock box in which a cylinder lock is directly attached to a lock box and resistance to breakage is increased.

シリンダ錠の扉への装着の態様は、例えば下記特許文献1及び図1に示すように、シリンダ錠1を収納したカップ状のシリンダ筒2を、錠箱3の側板及び扉4を貫通させて扉面外に突出させ、その突出部分を化粧リング5で覆う構造である。   For example, as shown in Patent Document 1 and FIG. 1 below, the cylinder lock 2 is inserted into the cup-shaped cylinder cylinder 2 containing the cylinder lock 1 through the side plate of the lock box 3 and the door 4. This is a structure that protrudes outside the door surface and covers the protruding portion with the decorative ring 5.

そして、シリンダ筒2そのものは、その開口端縁部外周面に形成された耳ブロック10、10及び錠箱3を貫通する装着杆6、6を介して錠箱3に固定される。   The cylinder cylinder 2 itself is fixed to the lock box 3 via the ear blocks 10 and 10 formed on the outer peripheral surface of the opening edge and the mounting rods 6 and 6 penetrating the lock box 3.

しかしながら、上記した構造のシリンダ錠の取付構造は、シリンダ錠を担持したシリンダ筒2を、一対の装着杆6、6を介して錠箱のフロント板及び背板の間に懸架するわけであるから、扉面を破壊しこれらの装着杆を切断してしまえばシリンダ錠を扉面から取り外すことは比較的容易であり、安全性に欠け未だ改良の余地がある。   However, the cylinder lock mounting structure having the above structure suspends the cylinder cylinder 2 carrying the cylinder lock between the front plate and the back plate of the lock box via the pair of mounting rods 6, 6. If the surface is destroyed and these mounting rods are cut, it is relatively easy to remove the cylinder lock from the door surface, and there is room for improvement due to lack of safety.

また、装着杆6の長さ方向(図1で前後方向)においてシリンダ筒が少し遊動することを完全に防止することはできず、更にまた、装着杆の弾性変形によってシリンダ筒2が図1で上下方向にも移動するから、シリンダ錠のテールピース7と錠止部材との係合が設計より狂う場合も考えられ、この場合には施解錠操作が円滑でなくなる。
特願2001−402546
Further, it is not possible to completely prevent the cylinder cylinder from slightly moving in the length direction of the mounting rod 6 (the front-rear direction in FIG. 1). Since it also moves in the vertical direction, there is a case where the engagement between the tail piece 7 of the cylinder lock and the locking member is out of design, and in this case, the locking / unlocking operation is not smooth.
Japanese Patent Application 2001-402546

そこで、この発明は、シリンダ錠を直接錠箱に取付けるようにし、破錠に対する抵抗力を高めた錠箱を提供し、もって上記した不都合を解消すると共に、錠前の安全性を向上させることを目的としている。   Therefore, the present invention aims to provide a lock box having a cylinder lock directly attached to the lock box and having increased resistance to breakage, thereby eliminating the above-mentioned disadvantages and improving the safety of the lock. It is said.

上記の目的を達成するため、この発明は、厚肉カップ状のシリンダ筒の開口端縁に少なくとも1個の係合突起を形成し、この係合突起、及び係合突起とは異なる角度位置におけるシリンダ筒の開口端縁の複数箇所に深い雌ねじ孔を形成し、一方、錠箱の室外側の側板にシリンダ筒の係合突起が通る突起穴を形成すると共に、錠箱内に、ダルマを一部包囲するようにして、錠箱の両側板の内面に接する取付ブロックを設け、他方、この取付ブロックの室外側の面にシリンダ筒の係合突起と係合する凹陥部を形成し、シリンダ筒を扉を貫通させてその開口端縁を錠箱の室外側の側板に接合させ、係合突起を突起穴を通して取付ブロックの凹陥部に係合させた状態で、錠箱の室内側の側板及び取付ブロックを貫通し、先端部を係合突起の雌ねじ孔に螺合させた第1取付ねじにより、シリンダ筒を錠箱の室外側の側板に呼び付けるように固定すると共に、室内側のサムターン座、扉内面、錠箱及びこの錠箱内の取付ブロックを貫通し、先端部をシリンダ筒の開口端縁に形成された雌ねじ孔に螺合させた複数の第2取付ねじにより、シリンダ筒を錠箱の室外側の側板に呼び付けるように固定したことを特徴とする。   In order to achieve the above object, the present invention forms at least one engaging protrusion on the opening edge of the thick cup-shaped cylinder, and the engaging protrusion and the angular position different from the engaging protrusion. Deep female screw holes are formed at a plurality of locations on the opening edge of the cylinder cylinder. On the other hand, a projection hole through which the engagement protrusion of the cylinder cylinder passes is formed in the side plate on the outdoor side of the lock box, and a dharma is placed in the lock box. A mounting block that contacts the inner surfaces of both side plates of the lock box is provided so as to surround the part, and on the other hand, a recessed portion that engages with an engagement protrusion of the cylinder tube is formed on the outer surface of the mounting block. And the opening edge of the door is joined to the side plate on the outdoor side of the lock box, and the engagement projection is engaged with the recessed portion of the mounting block through the projection hole, and the side plate on the indoor side of the lock box and Penetrate the mounting block and insert the tip into the female thread hole of the engaging projection. The combined first mounting screw fixes the cylinder cylinder so as to call the side plate on the outdoor side of the lock box, and penetrates the thumb turn seat on the indoor side, the inner surface of the door, the lock box, and the mounting block in the lock box. The cylinder cylinder is fixed so as to be called to the side plate on the outdoor side of the lock box by a plurality of second mounting screws screwed into the female screw holes formed at the opening edge of the cylinder cylinder. To do.

上記のように構成されたこの発明は、シリンダ筒を錠箱の室外側の側面に呼び付けて固定する第1及び第2取付ねじが厚肉のシリンダ筒の背後に隠れると共に、錠箱内における第1及び第2取付ねじが取付ブロックに被覆されるので、取付ねじを攻撃することによるシリンダ錠の取り外しが不可能になる。   In the present invention configured as described above, the first and second mounting screws for calling and fixing the cylinder tube to the outer side surface of the lock box are hidden behind the thick cylinder tube, Since the first and second mounting screws are covered with the mounting block, it becomes impossible to remove the cylinder lock by attacking the mounting screws.

また、シリンダ筒の係合突起を錠箱内に差し入れることによりシリンダ筒と錠箱、或いはシリンダ筒と錠箱内の錠止部材を制御するダルマとの相対位置関係を容易かつ正確に設定できるので、錠止部材の円滑な動作を保証できる、等種々の効果を奏する。   Further, by inserting the engagement projection of the cylinder cylinder into the lock box, the relative positional relationship between the cylinder cylinder and the lock box, or the cylinder cylinder and the dharma for controlling the locking member in the lock box can be set easily and accurately. Therefore, there are various effects such as ensuring the smooth operation of the locking member.

シリンダ錠を保持するシリンダ筒を厚肉にすると共に、これを錠箱の側板に呼び付ける取付ねじをシリンダ筒の背後に隠すようにし、かつ、錠箱を貫通する取付ねじの錠箱内における部分を取付ブロックで被覆するようにして不正破錠を不可能にした。   The cylinder cylinder that holds the cylinder lock is made thick, the mounting screw that calls it to the side plate of the lock box is hidden behind the cylinder cylinder, and the part of the mounting screw that penetrates the lock box inside the lock box Is covered with a mounting block, making unauthorized unlocking impossible.

以下、この発明の実施例を図2乃至図8を参照して説明する。
図2及び図3において符号2はシリンダ筒を示し、このシリンダ筒2は従来のものより肉が厚く、また、シリンダ錠1の軸線方向にドリルを通し難くするため、先端(図2で右端)が細くなるように成形されている。
Embodiments of the present invention will be described below with reference to FIGS.
2 and 3, reference numeral 2 denotes a cylinder cylinder. The cylinder cylinder 2 is thicker than the conventional cylinder cylinder, and the tip (right end in FIG. 2) is provided to make it difficult to pass a drill in the axial direction of the cylinder lock 1. Is shaped to be thin.

また、図示の実施例では、基端(図2で左端)部が断面小判形になるように肉を盗まれ、この基端部を薄肉のシリンダ筒カバー8で覆われている。   Further, in the illustrated embodiment, the meat is stolen so that the base end (left end in FIG. 2) has an oval cross section, and the base end is covered with a thin cylinder tube cover 8.

なお、図2で化粧リング5が上下で食い違っているように見えるのは、この化粧リングが扉の厚さが変化しても使用できる構造であることを示しており、また、化粧リング5を扉4に弾圧する圧縮コイルスプリング(図1参照)の図示を省略している。   In FIG. 2, the fact that the decorative ring 5 appears to be different from the top and bottom indicates that this decorative ring can be used even when the thickness of the door changes. Illustration of a compression coil spring (see FIG. 1) that presses against the door 4 is omitted.

一方、シリンダ筒2の開口端縁の少なくとも1ヵ所(図示の実施例では時計盤面に換算して12時の角度位置)に断面円形の係合突起9が形成されており、この係合突起9の中心軸線に沿って深い雌ねじ孔が形成されている。   On the other hand, an engagement protrusion 9 having a circular cross section is formed at least at one position of the opening edge of the cylinder cylinder 2 (in the illustrated embodiment, the angular position at 12 o'clock in terms of the clock face). A deep female screw hole is formed along the central axis of each other.

また、シリンダ筒の開口端縁の、上記係合突起とは異なる角度位置における複数箇所(図示の実施例では4ヵ所)にも同様に深い雌ねじ孔11、11が形成されている。   Similarly, deep female screw holes 11, 11 are formed at a plurality of locations (four locations in the illustrated embodiment) at different angular positions on the opening edge of the cylinder tube from the engagement protrusions.

なお、これはこの発明の必須の構成要件ではないが、装着時室外側となる上記雌ねじ孔の底部に鋼球を押込んでおくと、後記の取付ねじを攻撃するため雌ねじ孔の軸線方向にドリルを立てようとしても、その攻撃は鋼球に阻まれることになる。   Although this is not an indispensable component of the present invention, if a steel ball is pushed into the bottom of the female screw hole, which is the outside of the room at the time of installation, a drill is performed in the axial direction of the female screw hole to attack the mounting screw described later. If you try to stand up, the attack will be blocked by the steel ball.

他方、図4に示すように、ダルマ12を一部包囲するようにして、錠箱3内に取付ブロック20が設けられている。   On the other hand, as shown in FIG. 4, a mounting block 20 is provided in the lock box 3 so as to partially surround the dharma 12.

この取付ブロック20には、これを厚さ方向に貫通する3つのねじ通し孔15、15が形成されており(図5参照)、その内図5における中央のねじ通し孔には後述の第1取付ねじが、両側の一対のねじ通し孔には第2取付ねじが夫々挿通される。   The mounting block 20 is formed with three screw-through holes 15, 15 penetrating in the thickness direction (see FIG. 5), of which a central screw-through hole in FIG. The second mounting screw is inserted through the pair of screw holes on both sides of the mounting screw.

また、この取付ブロック20の錠箱側板内面に接する上、下面で、図5における両側のねじ通し孔15、15の開口部には、図6に示すように、錠箱の側板の厚さ程度の高さの付番しない環堤部が形成されており、図8に示すように、この環堤部と錠箱の側板に開口下付番しない係合孔との係合を利用して、取付ブロック20が錠箱3内に装着される。   In addition, as shown in FIG. 6, the thickness of the side plate of the lock box is approximately equal to the opening of the screw holes 15 and 15 on both sides in FIG. A ring portion not numbered is formed, and as shown in FIG. 8, by utilizing the engagement between the ring portion and an engagement hole not numbered on the side plate of the lock box, A mounting block 20 is mounted in the lock box 3.

更にまた、図7に示すように、取付ブロックの中央のねじ通し孔15の両端の開口部には、前記シリンダ筒の係合突起9(図2参照)と係合する凹陥部16が形成されている。   Furthermore, as shown in FIG. 7, recessed portions 16 that engage with the engaging projections 9 (see FIG. 2) of the cylinder cylinder are formed at the openings at both ends of the screw hole 15 at the center of the mounting block. ing.

なお、これらの凹陥部16、16を中央のねじ通し孔の両側に形成することはこの発明の必須の構成要件ではなく、扉の左右勝手に応じて取付ブロック20を裏返して錠箱内に装着する場合に備えてのことである。   It is to be noted that the formation of these recessed portions 16 and 16 on both sides of the central screw hole is not an essential component of the present invention, and the mounting block 20 is turned over and mounted in the lock box according to the right and left hand of the door. In preparation for the case.

上記のように構成されたこの発明の一実施例による錠箱は、図8に示すように、シリンダ筒2を扉4を貫通させてその開口端縁を錠箱3の室外側の側板に接合させ、係合突起9を突起穴を通して取付ブロック20の付番しない凹陥部に係合させた状態で、錠箱3の室内側の側板及び取付ブロック20を貫通し、先端部を係合突起の雌ねじ孔に螺合させた第1取付ねじ17により、シリンダ筒2を錠箱の室外側の側板に呼び付けるように固定する。   As shown in FIG. 8, the lock box according to the embodiment of the present invention configured as described above allows the cylinder cylinder 2 to pass through the door 4 and joins the opening edge to the side plate on the outdoor side of the lock box 3. In the state where the engaging protrusion 9 is engaged with the unnumbered recessed portion of the mounting block 20 through the protrusion hole, the side plate on the indoor side of the lock box 3 and the mounting block 20 are penetrated, and the tip portion is inserted into the engaging protrusion. The cylinder cylinder 2 is fixed so as to be called to the side plate outside the lock box by the first mounting screw 17 screwed into the female screw hole.

同様にして、室内側のサムターン座18、扉4の内面、錠箱3及びこの錠箱内の取付ブロック20を貫通し、先端部をシリンダ筒の開口端縁に形成された雌ねじ孔に螺合させた複数の第2取付ねじにより、シリンダ筒を錠箱の室外側の側板に呼び付けるように固定する。   Similarly, the thumb turn seat 18 on the indoor side, the inner surface of the door 4, the lock box 3, and the mounting block 20 in the lock box are passed through, and the tip is screwed into a female screw hole formed in the opening edge of the cylinder cylinder. The cylinder tube is fixed to be called to the side plate on the outdoor side of the lock box by the plurality of second mounting screws.

なお、この時錠箱3の室外側の側面、或いは両面に厚い焼入れした板状のプロテクター21を装着すれば、ドリルによる攻撃に対する抵抗力が更に高まる。   At this time, if a thick hardened plate-like protector 21 is attached to the outdoor side or both sides of the lock box 3, resistance to attack by a drill is further increased.
