Abstract
A rope restraining and selective release device is provided that may be incorporated with a carabiner or other device for selective interconnection to an anchor. The device employs a selectively rotatable cam lever with a plurality of teeth and gripping geometry that cooperates with the corresponding geometry in a rope cradle to restrain a rope. Tension in the rope will allow it to pass through the device in one direction, but tension in the opposite direction will prevent rope movement through the device.

1-6. (canceled)
A rope tension device, comprising:
- a cradle including a first side wall and a second side wall with a bracing structure extending between the first side wall and the second side wall, the cradle defining cylindrical surface with a cross section having a substantially linear portion extending from the first side wall and the second side wall;
- and
- a brake member pivotably coupled to the cradle, the brake member having a brake surface biased toward the cylindrical surface, the brake surface defining a plurality of teeth that face the cylindrical surface of the cradle;
- and
- wherein a gap is provided between the cylindrical surface and the plurality of teeth that varies in height along a lateral width of the cradle that extends between the first side wall and the second side wall.

A method of counteracting rope tension, comprising:
- providing a rope tension device, comprising:
- a cradle including a first side wall and a second side wall with a bottom wall extending between the first side wall and the second side wall, the bottom wall defining cylindrical surface with a cross section having a substantially linear portion extending from the first side wall and the second side wall;
- and
- a cam lever pivotably coupled to the cradle, the cam lever having a grip geometry biased toward the cylindrical surface, the grip geometry defining a plurality of teeth that face the cylindrical surface of the cradle;
- applying pressure to the cam lever to rotate of the cam lever and separate a distal end of the cam lever from a distal end of the cradle to create or expand an opening between the grip geometry and the bottom wall of the cradle;
- inserting one end of a rope into the opening;
- pulling a length of rope through the cradle;
- releasing the cam lever, thereby allowing the cam lever to rotate towards a proximal end of the device, to decrease the size of the opening, and to squeeze the rope between the cam lever the bottom wall of the cradle;
- and
- wherein withdrawal of the rope from the cradle in a direction that generally corresponds with the proximal end of the cradle is prevented, but movement of the rope through the cradle is possible.
