  • Publication number: 20150034201
    Abstract: A duct coupling apparatus includes a collar portion having a first end and a second end, a flange disposed about the collar portion in a manner that divides the collar portion into an first side and a second side, and a retaining structure extending from a surface of the flange towards the second side of the collar portion. The retaining structure and the collar portion define therebetween an annular region for receipt of a sealing element, such as an o-ring or gasket. The retaining structure prevents the sealing element from extruding outwards and/or failing when under pressure.

  • Patent number: 8857859
    Abstract: A preconditioned air connector (PCA) may be provided with a hollow body configured to pass a fluid flow, and a first mount assembly coupled to the hollow body. The first mount assembly may include a first cam joint with a first arcuate path of motion in a first plane generally tangential to the hollow body, a first mount coupled to the first cam joint, and a first lever coupled to the first cam joint. The first lever may be configured to actuate the first mount via a first transfer of motion through the first cam joint to draw the first mount inwardly toward the hollow body. In addition, the first mount may be configured to draw the hollow body and a mating component inwardly toward one another to pass the fluid flow between the hollow body and the mating component.

  • Patent number: 8146958
    Abstract: In certain embodiments, a preconditioned air connector has a hollow body configured to route a fluid therethrough and a hook member configured to mate with a cooperating element to draw the hollow body into fluid communication with a mating component. The preconditioned air connector also has a pivotable member actuatable along an arc tangential to the hollow body to direct axial translation of the hook member from a first position to a second position to draw the hollow body into fluid communication with the mating component. The pivotable member has an arcuate camming surface having a locking portion that secures the connector in a fully engaged position with respect to the mating component.

  • Patent number: 8146957
    Abstract: In certain embodiments, a PCA connector has a polyethylene body, wherein the polyethylene is durable, corrosion resistant, and exhibits excellent strength over a large range of temperature and moisture conditions. The polyethylene body may be described as a single structure with integral features, such as a bearing portion, a latch housing portion, a latch guide portion, and so forth. Thus, the number of parts is significantly reduced by the one-piece design of the body. In addition, the PCA connector may include a latching mechanism configured to secure the PCA connector to an aircraft. For example, the latching mechanism may include a pair of levers, which engage a pair of latches on opposite sides of the polyethylene body. In some embodiments, the levers may be rotated in opposite directions relative to one another to impart movement of the latches in the same direction, e.g., an axial direction.

  • Patent number: 7152886
    Abstract: A connector for coupling a preconditioned air source to an aircraft is provided. The connector comprises actuating members rotatably secured to a body. In one embodiment, the actuating members are supported, at least partially, by an integrated bearing assembly. The connector also comprises securing members that are positionably coupled to the actuating members. Accordingly, rotation of the actuating members displaces the securing members. Moreover, the actuating members comprise respective camming surfaces, wherein the camming surfaces define the axial position of the corresponding securing members.

  • Patent number: 6494502
    Abstract: A connector for joining two tubular members together includes inner and out concentric rings that are joined together in a manner that permits the outer ring to turn relative to the inner ring. The inner side of the inner ring has two seats to engage the ends of the tubular members that are to be joined together. The outer side of the inner ring and the inner side of the outer ring have camming members that when engaged cause the outer ring to exert compressive forces on the inner ring that in turn causes the inner ring to firmly grip the tubular members. The inner ring preferably has a gasket-like material in each of the seats that firmly engages the ends of the tubular members. When the camming members are disengaged, the ends of the tubular members may be inserted into or removed from the connector so as to separate the parts from one another.
