Abstract
Methods and systems are provided for a device. In one example, the device is configured to automatically grab and slip a line. The device is further configured to decrease degradation to the line by limiting a rotation of the device via contact with the line.
Claims20
A device configured to couple to a line, comprising:
- a cam shaped to increase a camming angle as rotation of the cam increases relative to a starting position, wherein the camming angle is from a center of a pivot point of the cam to a net contact point between the cam and the line and an axis orthogonal to the line.
A line grabbing device, comprising:
- a cam with a V-shaped groove increasing in width away from a bearing of the cam;
- a spring configured to overturn the cam towards contact with a line extending through the V-shaped groove;
- and
- a non-logarithmic portion of the cam configured to block rotation of the cam beyond a threshold rotation.
1 more element
A system for a line grabbing device, comprising:
- a line extending through an opening arranged between a groove of a cam and a recess of a baseplate, wherein the groove of the cam decreases in width in a direction away from the line.
