Abstract

【課題】家具等がこじ開けられ、中の物が盗まれるのを水際で防止する手だてがほしい。
【解決手段】錠前を施錠した時に“ＯＮ”になるスイッチと、扉をこじ開けられたときに“ＯＮ”になるスイッチを、直列に連結し、両方のスイッチが“ＯＮ”になった時に電気回路が閉ざされ、警報ブザーが鳴るようにした警報付き錠前で、盗難を未然に防ぐことができる。
【選択図】図１PROBLEM TO BE SOLVED: To provide a means for preventing furniture from being opened and stolen from being stolen.
A switch that is turned "ON" when the lock is locked and a switch that is turned "ON" when the door is opened are connected in series, and an electric circuit when both switches are turned "ON" With a lock with an alarm that closes and an alarm buzzer sounds, theft can be prevented in advance.

Description

本考案は、電気的感知機能を備えた警報付き錠前に関するものである。 The present invention relates to a lock with an alarm having an electrical sensing function.

ロッカーやキャビネットあるいは備え付けの貴重品ボックス等、家具の扉には錠前は取り付けてあるが、扉が無理にこじ開けられた時に警報が鳴る警報器が取り付けられることはなかった。 Locks, cabinets, or valuable boxes attached to furniture, such as locks, are attached to furniture doors, but alarms that sound an alarm when doors are forcibly opened are not attached.

ロッカーやキャビネットあるいは備え付けの貴重品ボックス等、家具の扉が無理にこじあけられて、中の物が盗まれるケースが多発しているので、これを水際で防ぎたい。 There are many cases where furniture doors such as lockers, cabinets or precious valuable boxes are forcibly opened and the inside is stolen.

上記家具等の扉を施錠する時、錠前の閂、あるいは回転式施錠カムがかけられた瞬間に、錠前内に設置されたスイッチが“ＯＮ”の状態になり、又、扉と扉枠との間隙が設計値をはるかに上回る間隔に開かれた時にそれを感知するするスイッチを扉内に設け両方のスイッチが“ＯＮ”になる瞬間に電池の電流が流れて、警報ブザーが、約１００デシベルの警報音を発生し、周囲に異常を知らせるようにした。又、電池からの電流を遮断しないかぎり、警報音は設定時間まで鳴り続ける。 When locking the doors of furniture, etc., the switch installed in the lock is turned “ON” at the moment when the lock or the rotary lock cam is applied. A switch is installed in the door to detect when the gap is opened at an interval far exceeding the design value. When both switches are “ON”, the battery current flows and the alarm buzzer is about 100 dB. An alarm sound was generated to notify the surroundings of abnormalities. Unless the current from the battery is cut off, the alarm sound will continue to sound until the set time.

上述のように盗人が家具の扉をこじ開けようとして、扉と扉枠の隙間を数ミリ開いた瞬間に警報が鳴るので、扉が完全に開かれる前に警報音に驚いた盗人を、何も取らずに退散させるることができる。 As described above, when a thief tries to open the furniture door, the alarm sounds at the moment when the gap between the door and the door frame is opened several millimeters. It can be dissipated without taking it.

閂式錠前の場合、錠前内に閂の出入りに応じて“ＯＮ”，“ＯＦＦ”の作動をするスイッチを、閂の後部に取り付け、このスイッチと、扉が無理にこじ開けられようとした時にこれを感知するスイッチと電池及び警報ブザーとを直列に結線し、コンパクトにまとめて錠前の近くの扉内又は、扉の内側に取り付けられるようにしたもので、外側からはこれを察知できない。
回転式施錠カムの場合はカムの回転に応じて“ＯＮ”，“ＯＦＦ”の作動をするスイッチを、錠前内のカムの始動部又は終動部に取り付ける。後は前述の閂式錠前の場合とおなじである。In the case of a saddle type lock, a switch that operates “ON” or “OFF” in response to the entry / exit of the scissors in the lock is attached to the rear part of the scissors, and this switch and the door are forced to open. The switch that senses the battery, the battery and the alarm buzzer are connected in series, and are compactly assembled so that they can be mounted in the door near the lock or inside the door, and this cannot be detected from the outside.
In the case of a rotary locking cam, a switch that operates “ON” and “OFF” in accordance with the rotation of the cam is attached to the start portion or the end portion of the cam in the lock. The rest is the same as in the case of the above-mentioned saddle type lock.

以下、本考案の実施例を図１及び図２に従って説明する。図１−ｉは閂錠の施錠前の状態を表す。図１−ｉｉは施錠後スイッチ▲３▼が“ＯＮ”になったのち、扉が無理にこじ開けられて、スイッチ▲４▼が“ＯＮ”となり、回路が全て閉ざされて、警報ブザーが鳴っている状態を表す。図２−ｉ及び図２−ｉｉは回転式施錠カムの場合で、動作は前述の閂錠の場合と同じである。又、スイッチ▲４▼は非接触型スイッチを含む。 Hereinafter, an embodiment of the present invention will be described with reference to FIGS. FIG. 1-i shows a state before locking the hook lock. Fig. 1-ii shows that after the lock switch (3) is turned "ON", the door is forcibly opened, the switch (4) is turned "ON", all the circuits are closed, and the alarm buzzer sounds. Represents the state of being. FIG. 2-i and FIG. 2-ii are the cases of the rotary lock cam, and the operation is the same as that of the above-described lock. The switch (4) includes a non-contact type switch.

図１（図１−ｉ、図１−ｉｉ）は閂錠における本考案の実施形態を示す。FIG. 1 (FIGS. 1-i and 1-ii) shows an embodiment of the present invention in a lock. 図２（図２−ｉ、図２−ｉｉ）は回転式施錠カム錠における本考案の実施形態を示す。FIG. 2 (FIGS. 2-i and 2-ii) shows an embodiment of the present invention in a rotary locking cam lock.
