    • According to one embodiment, a vibration damping apparatus for an elevator car includes an engaging apparatus, an interlocking mechanism, and a friction generation mechanism. The engaging apparatus includes a pair of engaging vanes. A gap between the vanes is narrowed when the car door apparatus is opened. The interlocking mechanism includes a lock lever and an engaging body, is released by an action of the engaging vanes holding the engaging body, and interlocks the hall door apparatus with operation of the car door apparatus. The friction generation mechanism generates a frictional force between the engaging vanes and the engaging body for suppressing a vertical vibration of the car when the engaging vanes are in a state of holding the engaging body.
    • 根据一个实施例,一种用于电梯轿厢的减震装置包括接合装置,联锁机构和摩擦产生机构。 接合装置包括一对接合叶片。 当轿厢门装置打开时,叶片之间的间隙变窄。 联锁机构包括锁定杆和接合体,通过保持接合体的接合叶片的作用而释放,并且通过轿厢门装置的操作使门厅装置互锁。 摩擦产生机构在接合叶片和接合体之间产生摩擦力,用于当接合叶片处于保持接合体的状态时抑制轿厢的垂直振动。
