Camming device stem

摘要

One embodiment of the present invention relates to an active camming device including a head member, a set of cam lobes, a connection system, and a retraction system. The cam lobes are configured to rotate between a retracted state and a spring biased extended state. The connection system includes a lengthwise cable coupled to the terminal. The retraction system is uniquely configured to enable selective engagement of the retracted state of the cam lobes with respect to the cam head. The retraction system includes slidably externally coupling a trigger and retraction sleeve to the cam lobes over the cable. A set of independent sleeves are also slidably coupled to the cable over the retraction sleeve between the trigger and cam lobes. The independent sleeves may be conically shaped and oriented to adjacently internest with one another so as to protect the retraction sleeve during operation of the refraction system.

主权项

1. An active camming device comprising:
a head member comprising a terminal and an axle; a plurality of cam lobes rotatably coupled to the axle, wherein the plurality of cam lobes are rotatable between an extended state and a retracted state with respect to the axle, and wherein the cam lobes are spring biased toward the extended state; a connection system configured to fixably intercouple the terminal with a cable, wherein the cable includes a connection point disposed on a lengthwise end opposite the terminal; a retraction system configured to selectively engage the retracted state, wherein the retraction system includes fixably coupling the plurality of cam lobes with a retraction sleeve and a trigger, and wherein the retraction sleeve and trigger are slidably externally coupled to the cable; and wherein the retraction system includes a plurality of independent sleeves slidably externally coupled to the cable between the plurality of cam lobes and the trigger, and wherein the plurality of independent sleeves are slidable and external with respect to the retraction sleeve, and wherein the plurality of independent sleeves substantially externally cover the retraction sleeve.
