Abstract:
A device for handling and stopping a pivotable shutter (A) has a fastening member (200) with a shaped plate (2) in order to apply in abutment with at least one of an inner face (A1), an edge side (A2) and a lower edge (A3) of the shutter (A). On the shaped plate (2) there are a fulcrum (600) and a holding element (5). An operating lever (1) is pivoted to the fulcrum (600) of the fastening member (200) and is engageable in the holding element (5) of the fastening member (200). The operating lever (1) is provided with a descending tract (11) intended to come in frontal abutment contact with a window sill (D). The operating lever (1) is equipped inside with means able to vary its shape so as to keep the shutter (A) in open position by abutment contact of its descending tract (11) with the sill (D) in dependence of the sill projection.
Abstract:
A handling device (1) for revolving doors, in particular window shutters (P), apt to be associated to a door having an inner face (P1), forming the handling side thereof, an outer face and a hinged edge (P2), comprising: a fastening member (2; 51) to be applied to said inner face (P1) at a preset position; a lever (12) comprising a fulcrum (13), located at said fastening member (2; 51), and a driving end that, with the lever (12) adjacent to said inner face (P1), projects from the hinged edge (B2) of a handgrip section (14); and means for blocking the door in an opened configuration, driven by said blocking/unblocking lever, comprising at least one blocking member (15; 25; 45; 58; 59; 71).
Abstract:
A system for generating electric energy from wind or hydraulic energy includes a turbine, and an electric energy generating device to which the turbine is connected through a shaft along a first axis. The turbine includes at least one blade, configured to perform a first rotary movement with respect to the first axis, and a second rotary movement with respect to a second axis, coinciding with the axis of the blade itself. This provides a system with structural features allowing high efficiency, facilitating installation in various environmental contexts, without risk of damage for the respective operational and structural integrity, at the same time. Additionally, the system has an essentially reduced environmental impact, as well as a low noise level so that it can be installed in an urban context or in any case close to built-up areas, i.e. near houses or buildings.
