OPERATION BODY AND PROTRUDING BODY OF FOOT-OPERATED INTERNAL LOCKING DEVICE

To provide a foot-operated internal locking device that can be used stably by embodying an idea to make it difficult to break an operation body, which uses the foot to lock and unlock the internal locking device.SOLUTION: An operation body of a foot-operated internal locking device may be damaged by a user intentionally or accidentally applying excessive tread force. To cope with this, the operation body is protected from damage by sloping or adding another member to appropriate parts of the operation body, such as an operating surface of the operation body or an upper face part of the operation body other than the operating surface.SELECTED DRAWING: Figure 3 【課題】足を使って内締まり錠の施解錠を行う操作体というものに対し、破損され難くする工夫を施すことで安定して使用できる足操作式の内締まり錠を提供する。【解決手段】足操作式の内締まり錠が備える操作体は、使用者が故意、或いは誤って過剰な踏力を加えることで破損する可能性がある。これに対してそれぞれの操作体の操作面、操作面以外の操作体の上面部など、適当な箇所を傾斜化したり、別部材を付加したりすることで操作体を破損から保護しようとする。【選択図】 図３
