THUMB TURN, LOCK FOR DOOR AND DOOR
To provide a thumb turn, a door lock and a door which can reduce collision sounds at the time of locking and unlocking.SOLUTION: A thumb turn 1, which is used to operate the lock which protrudes from the door edge to the locking position and retracts to the unlocking position by energizing force of a lock energizing spring, is composed of a rotating shaft 12 that drives the lock forward and backward by transmitting the rotational force, an operation knob 13 fixed in a non-rotating state at the tip of the rotating shaft 12, a pinion gear 14 engaged with the rotating shaft 12 and a pair of rotating dampers 15 for applying damping force that resists the rotation of the rotating shaft 12.SELECTED DRAWING: Figure 2
【課題】錠の施錠時及び解錠時に発生する衝突音を抑制することができるサムターン、扉用錠前、および扉を提供する。【解決手段】錠付勢ばねの付勢力によって扉端面より施錠位置に突出すると共に解除位置に退避する錠の操作に使用されるサムターン１において、回転力を伝達させることで錠を進退駆動させる回転シャフト１２と、回転シャフト１２の先端に回転不能な状態で固定された操作つまみ部１３と、回転シャフト１２に係合するピニオン歯車１４と、回転シャフト１２の回転に抵抗する減衰力を付与する一対の回転ダンパー１５と、を備えた構成とした。【選択図】図２
