Camming device
View Patent ↗A smaller-active camming device including a head member, a plurality of cam lobes, a retraction system, and a connection system. The head member includes a terminal and an axle. The axle comprises a unique configuration of multiple radial regions extending from opposite sides of the terminal. The radial regions of the axle are offset with respect to one another along at least one three dimensional axis. The offset of the radial regions is configured to reduce the geometrical interference of the cam lobes across the camming range.

wherein the axle includes a plurality of radial regions extending from opposite sides of the terminal, and wherein the plurality of radial regions are each offset with respect to at least one of the terminal and at least one of the other radial regions along at least one axis.
2. The system claim 1 , wherein each of the plurality of cam lobes are rotatably coupled to one of the plurality of radial regions.
3. The system of claim 1 , wherein the offset of the plurality of radial regions with respect to one another along the at least one axis includes offsetting each radial region distal of the terminal with respect to the adjacent radial region proximal of the terminal.
4. The system of claim 1 , wherein the plurality of radial regions includes at least four radial regions with two radial regions disposed on opposite sides of the terminal.
5. The system of claim 1 , wherein the plurality of radial regions are cylindrically shaped and intercoupled in an offset lengthwise configuration forming the axle.
6. The system of claim 1 , wherein the offset of the plurality of radial regions with respect to one another along the at least one axis is configured to geometrically reduce interference between the cam lobes in a refracted state.
7. The system of claim 1 , wherein the radial region directly proximal to the terminal has the largest diameter with respect to the distal radial regions.
8. The system of claim 1 , wherein an external surface of the distal most radial region with respect to the terminal is shaped and oriented to align with an external surface of the proximal most radial region with respect to the terminal.
9. The system of claim 8 , wherein the plurality of radial regions include a channel along the aligned external surfaces of the plurality of radial regions.
10. The system of claim 1 , wherein the stem is a substantially elongated member extending between the terminal and the thumb rest.
11. The system of claim 1 , wherein the terminal and axle are substantially T shaped.
12. The system of claim 1 , wherein the offset of the plurality of radial regions with respect to one another along at least one axis is configured to geometrically reduce interference between the cam lobes in a refracted state.
13. The system of claim 1 , wherein an external surface of the distal most radial region with respect to the terminal is shaped and oriented to align with an external surface of the proximal most radial region with respect to the terminal.
14. The system of claim 13 , wherein the plurality of radial regions include a channel along the aligned external surfaces of the plurality of radial regions.
15. An active camming device system configured for camming in a region below one inch comprising:
a head member comprising a terminal and an axle;

16. An active camming device head member system comprising:
a terminal, wherein the terminal is configured to fixably couple with an active camming device stem; and
an axle including a plurality of radial regions extending from opposite sides of the terminal, and wherein the plurality of radial regions are each offset with respect to at least one of the terminal and at least one of the other radial regions along at least one axis.
17. The system of claim 16 , wherein the active camming device head member is substantially T-shaped.
18. The system of claim 16 , wherein the offset of the plurality of radial regions with respect to one another along at least one axis includes offsetting each radial region distal of the terminal with respect to the adjacent radial region proximal of the terminal.
