Abstract
A conventional padlock is constructed such that a longer leg of an inverted U-shaped chord is mounted in a body to be freely slidable in the body but not to separate from the body, a shorter leg of the chord is formed with a notch for locking, and a tip end of a latch for locking is pushed into the notch for locking to establish a locking state. Such a conventional padlock is faulty in that it is unlocked only by applying a shock as strong as a human power to a side surface of the body on a longer leg side. A projection (2a) is provided on a notch for locking and a projection (3a) is provided on a tip end of a latch for locking so that the projections (2a, 3a) may be engaged with each other to establish a locking state, whereby a padlock is obtained which will not be unlocked even when a shock as strong as a human power is applied to a side surface of a body of the padlock on a longer leg side.

About padlocks. Dungeon technology
従来から、 種々の南京錠が広く市販され日常生活の色々な場所に簡便 に使用さている。 Conventionally, various padlocks have been widely marketed and are easily used in various places in daily life.
南京錠は構造が簡単であり比較的安価に製造出来るためと錠としての 安全度や強度を高める為に、 施錠用のラツチが一つのものや施錠用のラ ラツチが二つのもの、 逆 U字型の弦の二つの脚に施錠用の凹陥を設け本 体内の施錠球を凹陥に押圧して施錠するもの、 その他にも種々の機構を 施したものなどが市販され使用されている。 Padlocks have a single locking latch, two locking latches, and an inverted U-shaped padlock because they have a simple structure and can be manufactured relatively inexpensively, and to increase the safety and strength of the lock. Locking recesses are provided on the two legs of the string to lock the ball by pressing the locking ball in the body against the recesses, and those provided with various mechanisms are commercially available.
種々の南京錠のうち、 逆 U字型の弦の長脚は本体内で自由に滑動は出 来るが本体から離脱しないように本体に組み込まれ、 弦の短脚には施錠 用の切り込みを設け、 施錠用のラツチの先端が施錠用のラッチの後方に 設けたスプリングで短脚の施錠用の切り込みに押圧されて施錠状態にな る南京錠が一般的で広く使用されている。 Of the various padlocks, the long leg of the inverted U-shaped string can be freely slid inside the main body, but is incorporated into the main body so as not to come off from the main body, and the short leg of the string is provided with a notch for locking, Padlocks are widely used, in which the locking latch is pressed by a spring provided behind the locking latch into a locking notch on a short leg to be locked.
このような従来の一般的で広く使用されている南京錠の欠点は、 本体 を吊り下げた状態で、 長脚側の本体の側面に人力により木ハンマ-など で衝撃を与えるだけで筒単に解錠する事であり、 合鍵や特殊な器具が無
くても容易に解錠される事である。 The disadvantage of such conventional and widely used padlocks is that when the main body is suspended, the cylinder is unlocked simply by applying a shock to the side of the main body on the long leg side with a wooden hammer. Without a duplicate key or special equipment. It is easy to unlock even if not.
また、 南京錠は比較的に重要でなレゝ場所に多く使用されている反面、 倉庫や資材置き場等の盗難防止、 立ち入り禁止区域への侵入防止などの 重要な場所にも使用されており、 人力程度の衝撃で解錠するような欠陥 は大きな事故を発生する恐れがある。 Padlocks are often used in relatively important places, but they are also used in important places such as preventing theft of warehouses and material storage areas, and preventing entry into restricted areas. A defect that unlocks with a slight impact can cause a major accident.
従って、 本発明は、 逆 U字型の弦を有する南京錠で、 少なくても弦の 両脚の一つに施錠用の切り込みがあり、 その切り込みに施錠用のラツチ の先端が押圧されて施錠状態になる南京錠では、 南京錠を吊り下げた状 態で、 本体の側面のうち長脚側の側面に、 人力程度の衝撃を与えても解 錠する事が無い南京錠を提供することを目的としている。 発明の開示 Therefore, the present invention relates to a padlock having an inverted U-shaped string, and at least one of the legs of the string has a notch for locking, and the tip of the locking latch is pressed into the notch to be in a locked state. The purpose of Naru Padlock is to provide a padlock that does not unlock even if a shock of about human power is applied to the side of the long leg side of the main unit while the padlock is suspended. Disclosure of the invention
本発明は、 南京錠の逆 u字型の弦の脚に設ける施錠用の切り込みと施 錠用のラッチの先端に突起を設け、 施錠用のラッチの先端が施錠用の切 り込み押圧された時には両方の突起が互いに嚙み合うようにしてある。 また、 本発明は、 従来の南京錠の施錠用のラッチと施錠用の切り込み に突起を設けただけなので、 従来の此の種の南京錠を使用するのと同じ 使用方法で目的の南京錠を得る事が出来る。 図面の簡単な説明 The present invention provides a locking notch provided on an inverted u-shaped string leg of a padlock and a projection provided at a tip of a locking latch, and the tip of the locking latch is pressed when the locking notch is pressed. Both projections engage each other. Further, according to the present invention, since only a projection is provided on the conventional latch for locking the padlock and the notch for locking, the intended padlock can be obtained in the same manner of using the conventional padlock of this kind. I can do it. BRIEF DESCRIPTION OF THE FIGURES
第 1図はこの発明の南京錠の一部断面の正面図である。 発明を実施するための最良の形態 FIG. 1 is a front view of a partial cross section of the padlock of the present invention. BEST MODE FOR CARRYING OUT THE INVENTION
本発明をより詳細に説述するために、 添付の図面に従ってこれを説明 する。 The present invention will be described in more detail with reference to the accompanying drawings.
第 1 11は本発明の南京錠の施錠状態を示した一部断面の正面図である が、 弦の短脚 2に設けた施錠用の切り込みの突起 2 aと施錠用のラッチ 3の先端に設けた突起 3 a以外の形状と機構は従来の此の種の南京錠と 全く同じである。
従来の南京錠を操作するのと全く同じように本発明の南京錠の弦全体 を本体に押し込んでいくと、 第 1図のように突起 2 aと突起 3 aが嚙み 合った施錠状態になる。 11th is a front view of a partial cross-section showing the locked state of the padlock of the present invention, which is provided at the tip of a locking notch projection 2a provided on the short leg 2 of the string and a locking latch 3. The shape and mechanism other than the projection 3a are exactly the same as those of a conventional padlock of this type. When the entire string of the padlock of the present invention is pushed into the main body just like the operation of a conventional padlock, the projection 2a and the projection 3a are locked as shown in FIG.
従来の南京錠では、 弦全体を本体に押し込んでいくと、 突起 2 aと突 起 3 aが無いので、 施錠用のラッチ 3の先端の下面と施錠用の切り込み 部の下の方の面とが接して重なり、 弦の長脚 1の先端側にある圧縮ばね によって弦全体が常に上方に押し上げられて施錠状態になっている。 突起 2 aと突起 3 aが無い従来の施錠状態の時に、 長脚 1側の本体側 面に人力程度の衝撃を与えると、 本体と弦も施錠用のラツチ 3も衝撃を 加えた方向に移動するが、 衝撃が施錠用のラッチ 3に伝わるには施錠用 のラツチ 3の後方にあるスァリング 4を経て伝わるので、 施錠用のラッ チ 3が衝撃を加えた方向に移動するのは本体と弦が移動するのより少し 遅れるので、 施錠用のラッチ 3は施錠用の切り込みより一瞬だけ離脱し - 弦全体が長脚 1の先端側にある圧縮ばねによって常に本体から離脱する 方向に押されているので解錠してしまう。 In a conventional padlock, when the entire string is pushed into the main unit, there is no protrusion 2a and no protrusion 3a, so the lower surface of the tip of the locking latch 3 and the lower surface of the locking notch are below. The entire string is always pushed upward by the compression spring on the tip side of the long leg 1 of the string, and the string is locked. In the conventional locked state where there is no protrusion 2a and protrusion 3a, if an impact of about human power is applied to the main body side of the long leg 1 side, the main body and the string and the locking latch 3 also move in the direction in which the shock was applied. However, since the impact is transmitted to the locking latch 3 via the locking ring 4 behind the locking latch 3, the locking latch 3 moves in the direction in which the impact is applied only to the main body and the strings. The latch 3 for locking is released for a moment from the notch for locking as it moves a little later than the entire length of the string-the entire string is always pushed away from the main body by the compression spring at the tip end of the long leg 1 So unlocking.
本発明の南京錠の施錠状態の時には、 突起 2 aと突起 3 aが嚙み合つ ている以外は他の形状と機構は従来の南京錠と全く同じであり、 衝撃を 受けて施錠用のラッチ 3が移動するのが本体と弦の移動より少し遅れて も、 突起 2 aと突起 3 aは嚙み合ったままであり解錠しない。 産業上の利用可能性 When the padlock of the present invention is in the locked state, the other shapes and mechanisms are exactly the same as those of the conventional padlock except that the projection 2a and the projection 3a are engaged with each other. Even if the movement of the body is slightly delayed from the movement of the main body and the strings, the protrusion 2a and the protrusion 3a remain engaged and do not unlock. Industrial applicability
以上のように、 本発明の南京錠は、 長脚側に人力程度の衝撃を加えて も解錠しないし、 構造も従来の南京錠の構造に突起 2個を追加するだけ なので、 従来の南京錠を製造するのとほぼ同様に作る事が出来るうえ、 より安全度の高い南京錠を提供できる。
As described above, the padlock of the present invention does not release even if a shock of about human power is applied to the long leg side, and the structure of the padlock is only the addition of two projections to the structure of the conventional padlock. It can be made almost in the same way as it is, and can provide a more secure padlock.
