PUSH LATCH
PROBLEM TO BE SOLVED: To provide a push latch which acts suitably even if a gap between a door and an opening portion is narrow.SOLUTION: A push latch has a hook member 11 having a main rotation axis 20, a connection member 30 which is connected to the hook member 11 at a position that is away from the main rotation axis 20, a pressed part 16 which is located in the range which is from the main rotation axis 20 to a connection position in a straight line direction that passes a connection position between the connection member 30 and the hook member 11, and the main rotation axis 20, a cylindrical engaging portion 37 which is provided in the connection member 30 at a position that is different from the connection position between the connection member 30 and the hook member 11, a box member 45 in which a heart cam groove 60 to insert the engaging portion 37 is formed and a bearing portion to support the main rotation axis 20 is formed, a first pushing member 85 which is connected to the hook member 11 and the box member 45 and has pushing force in the rotation direction of the main rotation axis 20, and a second pushing member 42 which is connected to the hook member 11 and the connection member 30 and has pushing force to make the engaging portion 37 move so as to insert the engaging portion 37 in the heart cam groove 60.SELECTED DRAWING: Figure 3
【課題】扉と開口部との間の隙間が小さくても好適に動作するプッシュラッチを提供すること。【解決手段】主回動軸２０を有する鉤部材１１と、主回動軸２０から離れた位置で鉤部材１１に連結された連結部材３０と、連結部材３０と鉤部材１１との連結位置と主回動軸２０とを通る直線方向において主回動軸２０から連結位置までの間の範囲に位置する被押圧部１６と、連結部材３０と鉤部材１１との連結位置とは異なる位置において連結部材３０に設けられた円柱状の係合部３７と、係合部３７が挿入されるハートカム溝６０が形成されているとともに主回動軸２０を支持する軸受部が形成された箱部材４５と、鉤部材１１と箱部材４５とに接続され主回動軸２０の回転方向への付勢力を有する第一付勢部材８５と、鉤部材１１と連結部材３０とに接続され係合部３７がハートカム溝６０へ挿入されるように係合部３７を移動させる付勢力を有する第二付勢部材４２とを備える。【選択図】図３
