A pressure-sensitive relief panel for screened enclosures of swimming pools, spas or patios is disclosed. By securing the panels with a pressure release system the structure and panels can remain intact year round. If a weather event occurs either with or without warning the panels will automatically provide relief from loads or forces imposed by the event that could cause damage or even collapse of the structure.

A manual or motor activated enclosure, appropriate for any surface to be enclosed, comprising matching opposite cross-linked structures containing a set of profiles that fits in the field of telescopic modular pivoting roof structures, that upon retraction it is housed underground such that none of its components are visible above ground, and upon deployment it achieves complete enclosure of the area while proving for openings.

A canopy for selectively covering an area, such as a sports field includes at least two beams which span the area, at least two cross beams which are displaceable along the beams, a cloth which is attached to the cross beams, a drive which is configured to displace the cross beams with the cloth attached thereto along the beams, and a substantially flexible tensioning member fastened between the cross beams.

The invention relates to a gymnastics and therapy multifunctional installation by realizing rocking movements of the human body, wherein the installation comprises, configuration of liquid-containing spaces (1) by placing adjustable walls (2) with integrated support bars (3), a frame support base (4) in which a variable support frame is mounted, movable holders (52) mounted on the support frame and on the support bars (3) for mounting support components of the human body and cables (9), wherein on cables (9) a substrate base (10) is connected for the assembly of a substrate consisting various parts, where hand (16) and feet (15) parts of the substrate are used separately for exercises. A multifunctional device realizes the rocking movements by generating wave and currents through alternative components assembled into a chamber (24), transmitting movement in various system components and moving through arms (34) the frame support base (4) and support bars (3).

A release mechanism for a transport carriage used to move an elongated beam or truss is constructed using a non-linear bearing mounted on the carriage and connected to the truss and including upper and lower bearing mounting surfaces having complementary arcuate surfaces and a layer of layers of lower friction bearing material between them. The upper and lower bearing mounting surfaces being arranged to allow one plate to move relative to the other in an arcuate path in the direction of the space of the beam or truss.

A prefabricated foldable building module including a central core comprising first and second opposing fixed walls with roof and floor beams interposed therebetween; a plurality of vertically foldably connected walls mounted upon the first and second walls foldable out therefrom; a pair of roof panels, each foldably connected adjacent said roof beam; a pair of floor panels each foldably connected adjacent floor beam: characterized in that the wall panels, roof panels and floor panels may be folded out from their supporting structures in a defined sequence to form an enclosed/partly enclosed building structure, and may be re-folded in reverse sequence to original configuration. Standard modules can be stretched, or joined side by side, end to end or one on top of the other to form larger buildings.
