Patent

CA 2661424

Embodiments of the present invention provide pulley apparatuses that can be easily incorporated into block-and-tackle configurations. In some embodiments, a rope can be easily dropped into place and removed, rather than having to be threaded in. For example, the pulley housing can include a rope channeling structure near the end opposite the aperture, and the rope channeling structure can facilitate introducing the rope into engagement with the wheel and/or removing the rope from engagement with the wheel. In some embodiments, the rope channeling structure can prevent the rope from inadvertently becoming removed from the pulley. Some pulley apparatuses can comprise a minimal number of parts, which can significantly simplify the manufacturing process and provide for a more consistent final product.
