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.
Claims14
A rope restraining device, comprising:
- a hook adapted for interconnection to an anchor;
- a cradle rotatably interconnected to the hook, the hook comprising a first side wall and a second side wall that are interconnected by a bottom wall, the first side wall and second side wall comprising a taper near the bottom wall, wherein:
- the bottom wall in a lateral direction between the first side wall and the second side wall has a cylindrical profile defined by a linear cross section, and
- the bottom wall is an axial direction extending from a proximal end of the cradle to a distal end of the cradle has an arcuate profile relative that extends from a bottom surface of the cradle, wherein the arcuate profile relative to the bottom surface, and wherein portions of the first side wall and the second side wall bound the arcuate profile;
- a cam lever positioned within the cradle and configured to rotate relative to the cradle, the cam lever having a grip geometry comprised of a plurality of teeth that faces the arcuate profile, the grip geometry having a first lateral width at a proximal end that and a second lateral width at a distal end that is less than the width of the first lateral width;
- wherein the distal end of the cam lever is biased toward the distal end of the cradle;
- and
- wherein rotation of the cam lever separating the distal end of the cam lever from the distal end of the cradle creates an opening between the grip geometry and the bottom wall of the cradle that is adapted to receive ropes of more than one diameter;
- and
- wherein rotation of the cam lever in an operation of the distal end of the cam lever toward the distal end of the cradle decreases the size of the opening, and prevents withdrawal of the rope from the cradle in a direction that generally corresponds with the proximal end of the cradle.

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 literal 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.
2 more elements
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 literal 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.
