本考案はデッドボルトについて、その施錠突出時に不正
解錠操作等により外部から受ける押圧力に対して対抗し
うる機構を備えたデッドボルト施錠機構に関するもので
ある。[Detailed Description of the Invention] The present invention relates to a deadbolt locking mechanism that is equipped with a mechanism capable of resisting pressure applied from the outside due to an unauthorized unlocking operation when the deadbolt is locked and protruded.
以下本考案の一実施例について図面と共に説明すれば、
１は箱錠器体であり、デッドボルト２が前面板３より進
退し得るように設けられている。An embodiment of the present invention will be described below with reference to the drawings.
1 is a box lock body, and a dead bolt 2 is provided so that it can move forward and backward from a front plate 3.
４は案内ピンで゛ある。4 is a guide pin.
５はシリンダ錠又はサムタンにより回動されるデッドハ
ブであり、その駆動腕６に設けられた駆動ピン７がテ゛
ツドボルト２の被駆動凹部８に位置している。A dead hub 5 is rotated by a cylinder lock or a thumb tongue, and a drive pin 7 provided on a drive arm 6 of the dead hub is located in a driven recess 8 of the threaded bolt 2.
９はイ立置決め用スプリングである。１０は軸１１によ
り枢支された回動ストッパーであり、前記駆動腕６との
間に設けられたリンク１２により該駆動腕６に連動する
。9 is a spring for vertical positioning. A rotation stopper 10 is pivotally supported by a shaft 11, and is interlocked with the drive arm 6 by a link 12 provided between the drive arm 6 and the drive arm 6.
テ゛ツドボルト２には施錠位置において回動ストッパー
１０の自由端部１０ ａの回動軌跡とほぼ一致する形状
の衝合段部２ａが形成されており、施錠時において外方
へ向けて回動している該自由端部１０ ａが該衝合段部
２ａの内側に位置する。The threaded bolt 2 is formed with an abutment step 2a having a shape that substantially matches the rotation locus of the free end 10a of the rotation stopper 10 in the locked position, and rotates outward when the lock is locked. The free end 10a is located inside the abutment step 2a.
本考案は上記した如くに成るものであるがら、デッドボ
ルトの施錠突出時において回動ストッパーは該デッドボ
ルトの後退を阻止する位置にあり、外力に対抗して該デ
ッドボルトの解錠位置への移動を防止することができる
。Although the present invention is constructed as described above, the rotary stopper is located at a position that prevents the deadbolt from retreating when the deadbolt is extended to lock, and moves the deadbolt to the unlocked position against external force. Movement can be prevented.
本考案においては、デッドボルトを駆動する回動駆動腕
とストッパーとを別個の部材として設けているので、施
錠又は解錠操作時において、ストッパーをテ゛ツドボル
トに接触させる必要がなく、従って噛み込みを生じて動
作の円滑性を阻害するおそれがない。In the present invention, since the rotary drive arm that drives the deadbolt and the stopper are provided as separate members, there is no need for the stopper to come into contact with the deadbolt during locking or unlocking operations, thus preventing jamming. There is no risk of impeding smooth operation.
