International Classification:

F16F 3/087

Abstract:

An arrangement of fenders nested together for compact storage, the fenders including two or more cylindrical bodies having a cavity accessed through the fender top, the fenders being similar shape but graduated in size such that the cavity of a larger fender tensionally receives the next smaller sized fender, the outer diameter of the smaller fender equal to the inner diameter of the larger fender cavity. A fender has a rigid inner core surrounded by a compressible shell made of foam or similar material. The inner core has attachment points for a rope or line. The smallest nesting fender in the set has a cavity diameter sized to fit a commercially-available, off-the-shelf fender. The fenders may be separated and deployed at individual locations on a vessel, or kept together and deployed as a single fender capable of absorbing a greater impact than any of the fenders individually would absorb.

Inventors:

- Billings MT, US

Christopher Hamlin - Seattle WA, US

International Classification:

E05F 11/54

Abstract:

Improvements to movable closure systems which aid installability and reliability of said systems can include wheels running along the top and bottom of individual slidable elements, the wheels oriented horizontally and disposed within a track configured for receiving the horizontal wheels. The horizontal wheels reduce the vertical profile of the track-engaging portions of the slidable elements, enabling more of the slidable element to be used for glass or other aesthetically-preferable transparent materials. A track leveling system enables installers to more easily deploy and properly tune the system between floors and casings which are not perfectly flush. A compression jamb permits closure of the system via slidable elements pressing into the jamb to deflect it in order to better seal the closure comprised of the individual slidable elements. A durable hinge mechanism permits the sliding elements to rotate in order to stack the sliding elements at one end of the system.
