Patent ID: 7966941

Claim:
A trolley adapted to support and allow a harnessed rider to travel along a suspended cable, said suspended cable oriented along a longitudinal central axis, said trolley comprising: (a) a pulley housing comprising a substantially flat metal support flange plate, wherein said substantially flat metal support flange plate is arranged in a C-shaped manner and wherein said pulley housing includes at least one cross-sectional opening and at least one complete opening, (b) a handle assembly comprising at least one horizontal handle connected in a perpendicular orientation to a vertical shaft, said handle assembly pivotably mounted to said pulley housing in a downward orientation perpendicular to the central axis, (c) at least one pulley being mounted within said pulley housing with at least one pulley pin and said at least one pulley rotating freely within said pulley housing and aligned with said at least one cross-sectional opening, said at least one pulley having a circumferential groove that rides along the upper surface of said suspended cable and an axis of rotation that is generally horizontal and perpendicular to the central axis, (d) a latch assembly comprising a latch shaft, a latch shaft mounting bracket and a latch shaft seat, said latch assembly oriented and positioned such to cover said at least one complete opening and allowing for mounting and securing said trolley to said suspended cable, wherein said latch shaft is depressed such to open said at least one complete opening and permit entry of said suspended cable into said pulley housing such that said circumferential groove of said at least one pulley is placed on top of said suspended cable and wherein said latch shaft is closed thereby closing said at least one complete opening and securing said trolley to said suspended cable, (e) a brake assembly positioned to convert a constricting force into a dynamic frictional force, which when activated, brakes said trolley relative to said suspended cable on which said trolley is traveling, said brake assembly comprising at least one brake pad positioned within said at least one cross-sectional opening and positioned such to contact said at least one pulley, said at least one brake pad rigidly affixed to at least one caliper which is pivotably attached to said pulley housing, at least one hand brake lever rigidly affixed to said at least one horizontal handle, at least one brake cable affixed to said at least one hand brake lever at one end and another end affixed to said at least one caliper, whereby said trolley will travel along said suspended cable and said dynamic frictional force can be applied to said at least one pulley via said at least one brake pad in response to said constricting force applied by said rider to said at least one hand brake.
