Abstract
An electrically insulated trellis comprises a first array of parallel tubular members 2 and a second array of parallel tubular members 4. Each of the second array of parallel tubular members 4 is pivotably connected to a plurality of the first array of parallel tubular members 2 whereby to form a trellis 1. Each of the tubular members is formed from glass-reinforced polymer. A first set of fibres in the glass-reinforced polymer are substantially parallel and aligned in a first direction and a second set of fibres in the glass-reinforced polymer, distinct from the first set, are substantially parallel and aligned in a second direction different to the first direction.
Claims11
A method of using an electrically insulated trellis as a working platform to prevent falls through cavities between floor joists or rafters while performing a task from thereon, the method comprising:
- extending the electrically insulated trellis from a collapsed configuration to an expanded configuration, wherein the electrically insulated trellis includes:
- a first array of parallel tubular members;
- and
- a second array of parallel tubular members, each of the second array of parallel tubular members being pivotably connected to a plurality of the first array of parallel tubular members whereby to form a trellis,
- wherein each of the tubular members is formed from glass-reinforced polymer, and
- wherein a first set of fibres in the glass-reinforced polymer are substantially parallel and aligned in a first direction and a second set of fibres in the glass-reinforced polymer, distinct from the first set, are substantially parallel and aligned in a second direction different to the first direction;
- and
- disposing the electrically insulated trellis on the floor joists or rafters and over the cavities.
