    • A method and apparatus are provided, for allowing pets to ascend and descend on a foldable staircase having a plurality of stair treads operatively connected by articulating links in such a manner that the treads can be pivoted in unison from a stowed position of the staircase, in which the treads are substantially stacked upon one another, to a plurality of extended positions, in which the links position the treads in a spaced and parallel relationship to one another. A latch selectively secures the staircase in a selected one of the extended positions. The latch is configured for preventing further pivoting of the treads in either direction between the stowed and extended positions of the staircase, when the latch is engaged.
    • 提供了一种方法和装置,用于允许宠物上升和下降在具有多个阶梯踏板的可折叠楼梯上,所述多个阶梯踏板通过铰接连杆可操作地连接,使得踏板能够与楼梯的收起位置一致地枢转, 胎面基本上彼此堆叠在一起的多个延伸位置,在该多个延伸位置中,连杆将胎面彼此间隔开并且平行的关系定位。 闩锁选择性地将楼梯固定在所选择的一个延伸位置中。 闩锁被构造成用于在闩锁接合时防止踏板在楼梯的收起位置和延伸位置之间沿任一方向的进一步枢转。
