CRIME PREVENTION THUMB-TURN
To improve operability when a crime prevention thumb-turn is erroneously operated from an indoor side.SOLUTION: Included is an engaging element 44 which is supported so as to be engaged with a fixed cylinder 20 in the circumferential direction in the case of an illegal operation for applying an input torque to a knob 10 in a state in which a push button 13 is not pushed to a push position, and is arranged so as to be allowed to move to a release position where the push button is not engaged with the fixed cylinder 20 in the circumferential direction in the case of a normal operation. Rotation of the knob 10 and a thumb turn shaft 30 is prevented due to an engagement of the fixed cylinder 20 and the engaging element 44. The fixed cylinder 20 and the engaging element 44 are configured to convert an input torque applied to the knob 10 to apply a pushing force in a direction of disengaging the engaging element 44. When the push button 13 is pushed to the push position from the state in which the engagement is established against the input torque through the illegal operation, the engaging element 44 is moved to the release position by the push force.SELECTED DRAWING: Figure 1
【課題】防犯サムターンを屋内側から誤って不正操作を行った場合の操作性を良くする。【解決手段】押釦１３をプッシュ位置まで押し込んでいない状態で摘み１０に入力トルクを与える不正操作の場合に固定筒２０と周方向に係合可能な状態に支持され、正規操作の場合に固定筒２０と周方向に係合不可な解除位置への移動が許されるように配置された係合子４４を備える。固定筒２０と係合子４４の係合によって摘み１０とサムターン軸３０の回転が阻止される。固定筒２０と係合子４４は、摘み１０に与えられた入力トルクを変換して係合を解く方向の押し力を係合子４４に与える形状である。不正操作による入力トルクに抗して係合が成立している状態から押釦１３をプッシュ位置まで押し込む操作が行われる場合、押し力によって係合子４４が解除位置へ移動させられる。【選択図】図１
