| 发明名称 | Rope arresting apparatus | ||
| 摘要 | A rope arresting apparatus for use with a rope having a first end and a weighted second end is disclosed. The rope arresting apparatus includes a cam portion for exerting frictional force on the rope and a pinching portion. The cam portion has a resting position and a pinching position. At the resting position, the cam portion is in frictional contact with the rope when the tension on the weighted second end of the rope is less than or equal to tension on the first end of the rope. A pinching point is formed when the cam portion at the pinching position engages the rope against the pinching portion. | ||

| 主权项 | 1. A rope arresting apparatus, for use with a rope having a first end and a weighted second end, where the first end is gripped by a user, the apparatus comprising: a cam portion configured to exert frictional force on the rope, the cam portion having a resting position and a pinching position; a pinching portion; and a pinching point formed when the cam portion at the pinching position engages the rope against the pinching portion, wherein the cam portion at the resting position is in frictional contact with the rope when tension on the weighted second end of the rope is less than or equal to tension on the first end of the rope, said frictional contact at the resting position being releasable by the user lifting the rope off of the cam portion while pressing the rope against the pinching portion. | ||
