摘要： A lift apparatus configured to move a passenger platform of the lift apparatus between a first position and an elevated second position. A stairway of the example lift apparatus may be used as a stairway when the passenger platform is arranged in the first position. As the passenger platform is raised to the elevated second position, hinged steps of the stairway are transformed into a horizontal surface.

摘要： A compact, cleat-like, device for connecting the ends of a rope together where the rope is in tension. The device is generally planar, with two approximately flat surfaces, two approximately parallel sides and trifurcated ends. A central aperture is provided through the flat surfaces. The channels between the three end fingers are tapered, with the apices extending toward the aperture. In use, rope ends are inserted through the aperture, wrapped around two opposite channels and inserted back through the aperture. The device safely and securely maintains the connection between the rope ends. The rope can be easily removed, even with the rope in tension, by pulling one end of the rope back through the eye and unwrapping it from the channels.
摘要翻译： 用于将绳索的两端连接在一起的紧凑的，类似楔子的装置，其中绳索处于紧张状态。 该装置通常是平面的，具有两个近似平坦的表面，两个近似平行的侧面和三叉端。 通过平坦表面提供中心孔。 三个端部指状物之间的通道是锥形的，顶点朝向孔径延伸。 在使用中，绳索端部插入孔中，缠绕在两个相对的通道上并通过孔插回。 该装置安全且牢固地保持绳索端部之间的连接。 通过将绳索的一端拉回眼睛并将其从通道中解开，绳索可以很容易地被移除，即使绳索处于张紧状态。
