Abstract
An extendable protective arm is disclosed. The arm may protect an air, fuel, oil, or electrical conduit from harsh environments or the atmosphere during use. The arm may also connect the conduit between a moveable structure adapted to reciprocate relative to a fixed structure. The arm may extend in any number of dimensions.
Claims15
An extendable arm assembly configured for use with an aircraft wing, comprising:
- a housing secured to the aircraft wing, the housing having a first curved guide, the first curved guide defining a first curved slide path inside the housing;
- an intermediate arm nested inside the housing and including an second guide, the second guide defining a second slide path inside the intermediate arm, the intermediate arm including a distal arm nested inside, each guide including a roller catch positioned at each end of the guide and a roller disposed in each guide, each roller attached to one of the intermediate arm and the distal arm, the intermediate arm configured to reciprocate along the first curved slide path in at least two dimensions;
- and
- a flexible conduit fully contained within and extending through the housing and intermediate arm to communicate a flow.
