US Patent 11555364 High expansion anchoring system

A slip assembly includes a first support cone configured to move a first extension ramp between retracted and extended positions. The first extension ramp is biased towards the retracted position by a first biasing member. The slip assembly further includes a second support cone configured to move a second extension ramp between retracted and extended positions. The second extension ramp is biased towards the retracted position by a second biasing member. The slip assembly further includes a slip member disposed between the first extension ramp and the second extension ramp. The slip member is configured to slide between retracted and extended positions along an outer surface of the first extension ramp and along an outer surface of the second extension ramp. A shank of the slip member is held in a cage by a retainer that moves radially when the slip member moves between the retracted and extended positions.
