Abstract: The present disclosure relates to, for example, an article carrier mounting leg, comprising a leg frame having an upper end configured to receive a mounting portion of an article carrier thereupon, and a lower end configured to rest against a leg mounting point, an article carrier mounting element configured to engage with the article carrier mounting portion, an outer clamp jaw movably connected to and outwardly extending from an outer clamp mounting point within the leg frame, and a threaded tightening mechanism. Further embodiments, including methods of attaching an article carrier mounting leg to a leg mounting point, are also provided.

Abstract: The present invention relates to a device to slidingly connect an end of a first element to a side of a second element, the second element side having a channel extending therealong, the device comprising a device body having a fixable end and a slidable end, the fixable end being adapted to be affixed to the end of the first element, and a protrusion extending from the slidable end of the device body, configured to engage with the channel of the second element and slide therealong, wherein the device body is formed in at least a first and second device body portion, the first and second device body portions being separable.

Abstract: A system for optimizing one or more environmental parameters of an enclosed space comprising first and second relatively enclosed regions, such as a living space and a roof space within a building, is disclosed. The system comprises an internal sensor, in the first region, and an external sensor, external to the enclosed space, for measuring respective environmental parameters. The system also comprises a controller and a diverter valve. The controller is configured to specify the first region's ideal internal environmental parameter, and compare this specified parameter with the measured first region's internal parameter and the measured external parameter to determine whether the diverter valve directs air from the first or second enclosed region to exhaust through the ventilator.

Abstract: A roof-mounted ventilator comprising a plurality of blades is disclosed. Each blade comprises front and back blade faces and leading and trailing edges. When the ventilator is viewed in side profile, the blades are positioned and configured such that a line of sight into the interior of the ventilator is substantially restricted or obstructed. Restricting or obstructing the line of sight into the ventilator can reduce or prevent various particles, such as water droplets, debris, dust and light, from entering the ventilator interior. For example, rain is thereby forced to strike a face of the blades, thus preventing direct access into the ventilator interior. The blade itself may include additional features, such as a lip that extends along the length of the leading edge, to further prevent particles from entering the ventilator interior, or to redirect the particles away from the ventilator interior in a controlled manner.

Abstract: A rotor ventilator comprising a ventilator stator for mounting to a structure and a ventilator rotor for mounting and rotation with respect to the ventilator stator is disclosed. The ventilator further comprises a cover for positioning over the ventilator rotor and mounting to the ventilator stator. The cover comprises a central portion surrounded by an outer substantially concave portion. The outer concave portion of the cover may protect the ventilator from environmental conditions/elements, such as by redirecting particles, water droplets, debris and dust, etc away from the interior of the ventilator. The outer concave portion may act as a trough, from which the particles can then be directed off the cover. The trough may also act to prevent the particles from escaping over the sides of the cover, and into the ventilator.
