  • Patent number: 10119266
    Abstract: A sparse-isogrid columnar lattice structure including rigid ring frames connected by a mirrored symmetric double helix pattern comprised of first shell hinge elements in a first helical pattern and second shell hinge elements in a second helical pattern oriented in an opposite direction to the first helical pattern and congruent thereto. The helical axes of the first and second helical patterns intersect the respective centers of the ring frames. The first and second shell hinge elements are configured to stow in a stored energy state when the ring frames are collapsed toward one another along the helical axis, and the first and second shell hinge elements are configured to release the stored energy to deploy to a restored state and extend the ring frames apart from each other along the helical axis when deployed to form a stable rigid axial column in a restored state.

  • Publication number: 20120102850
    Abstract: An extendable and retractable column which is formed from at least three linked sections or chains. The linked sections include a plurality of individual segments linked end to end. As the linked segments are extended, each of the individual segments of the linked chains engage individual segments of adjacent linked sections to form a column. As the linked sections are retracted, each of the individual segments of the linked sections disengage from the individual segment of the adjacent linked sections and the individual linked sections may be rolled up into a multi-sided form for compact storage.

  • Publication number: 20120079778
    Abstract: A rapid deployment and retraction telescoping mast system for controlling the height of a mast. A retraction mechanism including a resilient member, a retraction reel, a reel shaft, and a motor disposed about a frame. The resilient member extends from the retraction reel and is rigidly attached to a top tube of the mast through a sealed passage. The reel shaft rotates the retraction reel and winds the resilient member creating a retraction force on the top tube causing controlled retraction of the mast. A deployment mechanism including a compressor, storage tank, exhaust valve and isolation valve arranged about the frame and in communication with the mast. The compressor generates pressurized air to be communicated to the mast when the isolation valve is in the open position. The increase of pressure generated by the deployment mechanism provides a force within the mast thereby controlling its deployment.

  • Patent number: 8042305
    Abstract: A deployable structural assembly is provided along with associated deployment mechanisms and associated methods of forming and deploying the structural assembly. In one exemplary embodiment, the structural assembly includes a plurality of structural side elements formed from furlable truss structures. The truss structures may include spaced apart longitudinal members, members extending substantially transversely between the longitudinal members, and diagonal members extending between the longitudinal members at an acute angle relative thereto. A plurality of interlocking elements are located along the edges of the longitudinal members and are configured to engage interlocking elements of an adjacent structural side element. In one embodiment the truss structures may be formed to include at least one material layer having the longitudinal members, the cross-members and the diagonals formed as an integral structure.

  • Publication number: 20110252720
    Abstract: This invention relates to a tower for a wind turbine, comprising one or more tubular tower sections, having an outer jacket wall and an inward directed flange in its lower and upper ends, and at least one platform arranged inside the tower for facilitating access for maintenance and repairs to the inner of the tower and to the nacelle. The tower also comprises a support structure including at least three elongated tensile load carrying members, which each is attached in its upper end to the upper flange of the tower section and in its lower end to the lower flange of the tower section and which supports one or more platforms that are suspended by the tensile load carrying members while at least one ladder is attached to the platforms. The at least one ladder is stabilized in the horizontal direction by transversal tensile load carrying members extending from the ladder to the tensile load carrying members that are vertically arranged between the upper and lower flanges.

  • Publication number: 20110185648
    Abstract: The present invention is an improved apparatus and method for forming a retractable tower or column. The present invention includes pointed hooks wherein the hooks are attached to each section of a section chain, one in a horizontal direction and one in an off-set manner. The section chains are placed on a take up mechanism in an operable position and then raised utilizing a motor. As the section chains are raised, they are guided by a guide tower, rollers, shims, and gear racks into a position whereby hooks from adjacent sections of the section chains form coupled engagements. The coupled engagement of the hooks of the sections of each adjacent section chains thereby form the column.

  • Patent number: 7966777
    Abstract: A telescoping mast apparatus has a plurality of nesting cylinders. The telescoping mast apparatus has a plurality of telescoping cylinders and a plurality of straps. The plurality of cylinders is extendable from a base. Each strap extends from near a bottom of an outer cylinder, around an upper roller near a top of the outer cylinder, and is attached near a bottom of an inner cylinder. The plurality of straps and the plurality of telescoping cylinders intercouples in series with alternating straps and cylinders. The plurality of cylinders is extended by retracting a first strap from the outer cylinder, which raises an intermediate cylinder, which retracts the intermediate strap from the intermediate cylinder, which raises the second intermediate cylinder.
