Abstract: The present invention relates to a rotating and sliding boat boarding door mechanism configured to aid the vessel's occupants in their ingress and egress to and from the vessel. More particularly, the present invention provides a rotating and sliding boat boarding door assembly and system that slidingly moves into a recess in the vessel's exterior (e.g., side, transom, and/or gunwale) that has been configured to receive and maintain the boarding door assembly in a position where it is out of sight when fully recessed.

Abstract: A retractable convertible top for a pleasure craft, including a canvas type fabric and stowable linkage mechanism, is described. This convertible top may be fully deployed and retracted automatically to provide a quick and efficient means of providing shelter for the open cabin of a pleasure craft while still allowing easy entrance and egress from the cabin when the top is fully deployed. The convertible top may be fully stowable within a small volume storage bin with watertight covers. The stowage bin may be integrated into the craft. The craft's existing hydraulic and control systems may be utilized to automatically deploy and retract the convertible top.

Abstract: A vacuum cup for a material handling system includes a body portion and a perimeter seal that functions to substantially seal against an object. The vacuum cup may transport the object when a partial vacuum is applied to the vacuum cup to retain the cup to the object. The vacuum cup includes a relief port that functions to at least partially relieve the vacuum from the vacuum cup as the vacuum cup is moved relative to the object. The relief port may include a sealing member that may engage a surface of the object to close the relief port. When the vacuum cup is initially pulled or moved away from the object, the relief port is at least partially opened and allows the cavity to be vented to at least partially relieve the vacuum within the cavity.

Abstract: A vacuum device for a material handling system includes a vacuum device body and a sealing element. The vacuum device body has a vacuum passageway in which a vacuum is generated in response to activation of a pressurized air supply that forces pressurized air through a venturi device. The sealing element moves to a sealing position to substantially seal the vacuum passageway when the air supply is activated, and is urged toward the sealing position via pressurized air that is diverted from an inlet of the vacuum device to the sealing element. The sealing element moves to substantially vent the vacuum passageway when the air supply is deactivated. The vacuum passageway may be in fluid communication with a vacuum cup, which seals against the object when the sealing element is at the sealing position and the vacuum generating device generates at least a partial vacuum in the vacuum passageway.

Abstract: A vacuum cup for a material handling system includes a body portion and a perimeter seal that functions to substantially seal against an object. The vacuum cup may transport the object when a partial vacuum is applied to the vacuum cup to retain the cup to the object. The vacuum cup includes a relief port and sealing member that function to at least partially relieve the vacuum from the vacuum cup to allow the vacuum cup to be detached from the object with a reduced force, even while the vacuum is applied. The sealing member may engage a surface of the object to close the relief port. When the vacuum cup is initially pulled or moved away from the object, the sealing member is at least partially separated from the object and allows the cavity to be vented to at least partially relieve the vacuum within the cavity.
