Abstract
A larger active camming device including a plurality of opposed camming lobes, a cam head, a retraction system, and a connection system. The cam head includes a stem end and two parallel axles coupled to the stem end. The retraction system is a unique system comprised of a trigger, flexible trigger wires, control horns, and torsion springs. The control horns couple the trigger to the camming lobes and are configured to reduce buckling and allow greater camming range. The retraction system can also include a retraction locking mechanism. The locking mechanism is used to store the cam in a retracted and locked position until it is needed by the climber. When needed, the climber can easily unlock and extend the camming lobes with one hand.
Claims17
An active camming device comprising:
- a cam head comprising a stem end coupled to two parallel axles;
- a plurality of camming lobes rotatably coupled to the two axles;
- a connection system coupled to said stem end, and said connection system comprising a stem coupled to said stem end, and a thumb rest coupled to said stem;
- a retraction system coupled to the plurality of camming lobes;
- said retraction system further comprising:
- a trigger slidably coupled to said connection system,
- a plurality of trigger wires coupled to said trigger,
- a plurality of springs coupled to the plurality of camming lobes, and
- a plurality of control horns, each control horn rotatably coupled to one of the axles and having
- a lever arm coupled to said trigger wires, and
- a portion extending from the lever arm that is coupled to each camming lobe by a positive drive.
An active camming device comprising:
- a cam head;
- a plurality of camming lobes coupled to said cam head;
- a connection system coupled to said stem end, and said connection system comprising a stem coupled to said stem end, and a thumb rest coupled to said stem;
- a retraction system coupled to the plurality of camming lobes;
- said retraction system further comprising:
- a trigger slidably coupled to said connection system, and
- a plurality of springs coupled to the plurality of camming lobes;
- a retraction locking mechanism comprising:
- a protrusion fixably coupled to said connection system;
- a slot and decent on said trigger adapted to engage the protrusion;
- whereby the retraction system is held in a retracted position.
An active camming device comprising:
- a cam head comprising a stem end coupled to an axle;
- a plurality of camming lobes rotatably coupled to said axle;
- a connection system coupled to said stem end, and said connection system comprising a stem coupled to said stem end, and a thumb rest coupled to said stem;
- a retraction system coupled to the plurality of camming lobes;
- said retraction system further comprising:
- a trigger slidably coupled to the connection system,
- a plurality of trigger wires coupled to said trigger,
- a plurality of springs coupled to the plurality of camming lobes, and
- a plurality of control horns, each control horn rotatably coupled to the axle and having
- a lever arm coupled to said trigger wires, and
- a portion extending from the lever arm through and rotatably coupled to an inner camming lobe, to an outer camming lobe that is coupled to the control horn by a positive drive.
