An adjustable header assembly includes a first piece of material and a second piece of material and at least one bracket. The first piece of material has a fixed length and the second piece of material has an adjustable length. In operation, the length of the second piece of material is adjusted until the second piece of material is proximate wall studs. The second piece of material is then coupled to the studs and the at least one bracket is coupled to the first and second pieces of material.

The innovation relates to a pool covering system that is usable as a flooring surface. The pool covering system includes brackets and support beams spanning the pool opening. The beams provide structural support to cross members and flooring placed on top of the beams. The pool covering system does not require significant drainage of the pool and does not damage the pool structure during installation and use.

A deck framing system includes a perimeter support member that has a joist support wall and a web wall extending perpendicularly from the joist support wall and an overhang wall extending perpendicularly from the web wall. First and second joist support brackets include a joist support portion and a pair of attachment wings, where each one of the pair of attachment wings contacting the web wall of the perimeter support member. First and second joists each include a deck support wall and a lower wall. The deck support walls of the first and second joists are disposed between the overhang wall and the joist support portions, and the lower walls are disposed between the joist support portions and the joist support wall.

Extendible slit tube members and methods for manufacturing extendible slit tube members are provided. In one aspect, an extendible member (10) comprises a laminated shell (2) of plural fibre reinforced layers (P1-P5) constructed and arranged to be configurable between a coiled form and an extended form. In the extended form (12) the shell is resiliently biased in the form of an elongate tube having longitudinal edges (14) defining a slit (3) along its length and wherein the shell can be opened out at the slit to assume a flattened form in which it can be wound about an axis extending transversely to its longitudinal direction to assume its coiled form (11). In the region of one or both longitudinal edges (50), the amount of reinforcing fibre is less than in the region between the edge regions (51). In another aspect, a flexible cord (40) may be attached along the edge of a shell.

A mast assembly (10), a method of deploying a mast (20), a slit locking clamp (50) for a mast and to a support assembly (14) for an extendible member (20) are provided. The mast assembly (10) comprises an extendible mast (20) configurable between a coiled form and an extended form. When extended the mast is resiliently biased in the form of an elongate tube having a slit along its length defined by longitudinal edges of the mast. When coiled the mast is opened out at the slit to a flattened cross section and wound about an axis extending transversely to the longitudinal extent of the mast. A slit locking clamp (50) clamps across the slit in the mast at a position along the length of the mast so as to stabilise one edge relative to the other.

A trussed collapsible tubular mast includes a deformable beam having an extended state, a flattened state, and a rolled state, where a stiffness and strength of the deformable beam in the extended state is greater than a different stiffness and a different strength of the deformable beam in the flattened state. At least one collapsible tubular mast wall has a plurality of truss members of a first material having a first material thickness. At least one truss member is disposed substantially perpendicular to a longitudinal axis of the trussed collapsible tubular mast. Disposed between the truss members is a wall area of a second material thickness less thick than the first material thickness.

Building stud (10) for forming a framework for mounting wall panels, comprising a first (12) and a second (14) flange portion and a web portion (16) interconnecting the flange portions. The flange portions comprise a planar, elongated wood fibre member (18, 20), and the web portion comprises a polymer based and/or cellulose fibre based sheet member (22) including a first (24) and a second (26) rectilinear line of weakness, which lines of weakness are parallel and along which the sheet member is foldable to enable folding the building stud from a retracted storage position to an expanded mounting position.

An antenna assembly and related methods are described. The antenna assembly (1) comprises an extendible mast (2) constructed and arranged so as to be configurable between a coiled form and an extended form. The extended mast (2) is resiliently biased in the form of an elongate tube having a slit along its length. The coiled mast is wound about an axis extending transversely to the longitudinal extent of the mast. An antenna (6) is integrally coupled to the mast such that when extended, the mast supports and positions the antenna, and when coiled, the mast and antenna are coiled together.

An adjustable header assembly includes a first piece of material and a second piece of material and at least one bracket. The first piece of material has a fixed length and the second piece of material has an adjustable length. In operation, the length of the second piece of material is adjusted until the second piece of material is proximate wall studs. The second piece of material is then coupled to the studs and the at least one bracket is coupled to the first and second pieces of material.

Building stud (10) for forming a framework for mounting wall panels, comprising a first (12) and a second (14) flange portion and a web portion (16) interconnecting the flange portions. The flange portions comprise a planar, elongated wood fibre member (18, 20), and the web portion comprises a sheet metal member (22) including a first (24) and a second (26) rectilinear line of weakness, which lines of weakness are parallel and along which the sheet metal member is foldable to enable folding the building stud from a retracted storage position to an expanded mounting position.
