Abstract
A portable line ascending device to enable users to ascend an incline on sliding or rolling sporting by travelling up an anchored line with the line ascending device. The device includes a mount, a plurality of sheaves connected to the mount, a motor driving the plurality of sheaves, and a power supply to supply electricity to the motor. The plurality of sheaves are configured to enable a line to be wound around at least a portion of each sheave of the plurality of sheaves and operable to engage the line to pull the line through the plurality of sheaves such that the line ascending device travels along the line.
Claims13
A line ascending device for use with a line, the line ascending device comprising:
- a mount;
- a plurality of sheaves rotatably connected to the mount;
- each sheave of the plurality of sheaves being connected to a gear member such that each sheave is rotationally driven by its gear member;
- each gear member being connected to at least one other gear member to be rotationally driven by said at least one other gear member;
- at least one gear member being connected to a gearbox to be rotationally driven by the gearbox;
- a motor driving the gearbox;
- a power supply to supply electricity to the motor;
- the plurality of sheaves being coplanar and located to enable the line being wound around at least a portion of each sheave of the plurality of sheaves;
- the gear members and the plurality of sheaves being configured to produce a synchronized tangential velocity across the plurality of sheaves to provide a uniform pull of the line through the plurality of sheaves;
- and
- the plurality of sheaves being operable to engage the line to pull the line through the plurality of sheaves to cause the device to travel along the line.
