Systems and methods for controlling rope
First Claim
1. A rope control device for controlling a rope, comprising:
- a central opening defined between two rigid elongate sides and two bridges bridged between the two rigid elongated sides, wherein the two rigid elongate sides are generally straight and parallel to each other;
a bar pivotally and slidably connected to one of the two rigid elongate sides and having a notch configured to engage the other of the two rigid elongate sides in a closed position, wherein the bar pivots away from the closed position to disengage from the other of the two rigid elongate sides, wherein the bar divides the central opening into first and second openings in the closed position, wherein the bar can slide toward and away from the two bridges to change the relative sizes of the first and second openings;
first and second projections extending away from the central opening and away from a first one of the two bridges, the first and second projections having respective distal tips separated from each other to define a first rope inlet;
third and fourth projections extending away from the central opening and away from a second one of the two bridges, the third and fourth projections having respective distal tips separated from each other to define a second rope inlet;
a first recess between the first and second projections;
a second recess between the third and fourth projections; and
friction surfaces within each of the first and second recesses.

Abstract
A rope control device a main body defining a central opening and first and second side portions, projections extending from the main body, an end recess defined by the first and second projections, an end friction surface formed at a juncture of a projection and the main body, and a bar. With the bar in a first position, the first rope portion is extended through the central opening and at least partly around the bar. With the bar in a second position, the main body and the bar define first and second opening portions of the central opening and the first rope portion is extended through the first and second opening portions and at least partly around the bar. The second rope portion is arranged within the first end recess such that, when the rope is under tension, the second rope portion frictionally engages the first end friction surface.

wherein the at least one projection extends beyond an outer surface of one of the two rigid elongate sides. - View Dependent Claims (12, 13)
