Problems solved by technology

[0003] In known fume and heat extraction devices of the type indicated above (an example of which is disclosed in US-4068417), to manage the displacement of the opening of the shutter, a motor-driven actuator is usually provided, for example, an electrically operated Actuators or hydraulically operated actuators, in addition to reliability issues in terms of their risk of being subject to damage or failure, entail problems of overall size and cost
In addition, the presence of such actuators may limit the cross-section of the passage of smoke and heat through the openings

Embodiment Construction

[0014] initial reference Figures 1 to 3 , the fume and heat removal device according to the present invention basically comprises a support frame 1 and a swingable shutter 2 which can be positioned relative to the frame 1 at figure 1 and 2 Closed position shown with image 3 Shift between the open positions shown.

[0015] The frame 1 can be applied at an opening of a generally vertical wall, which is usually arranged slightly inclined relative to the vertical in an area of ​​10°, for example in a direction opposite to the opening direction of the shutter 2 .

[0016] The shutter 2 is hinged at its bottom side 3 to the frame 1 by one or more hinges 4, and at the figure 1 and 2 In the closed position shown, it blocks the opening in a fluid-tight manner. exist image 3 In its fully open position shown, the shutter 2 is rotated from the closed position downwards about the axis of the hinge 4 by an angle of eg about 60°, thereby enabling smoke and heat to escape towards the...

Abstract

A smoke and heat evacuator that can be applied at an opening of a generally vertical wall of a closed environment, comprising a supporting frame (1) bearing a shutter (2), which oscillates between a normally closed position and an open position via at least one lateral linkage (8) comprising a first arm (9) that, in the closed position, extends obliquely, with a top end (10) articulated to the shutter (2) via a slider (12) subject to the downward-thrust action of a spring (17) and with a bottom end (13) articulated to the supporting frame (1) via a second lengthenable arm (15).

Description

technical field [0001] The invention relates to a device for extracting smoke and heat from a closed environment in the event of a fire. [0002] More specifically, the subject of the invention is a discharge device that can be applied at an opening in a generally vertical wall of a house and that comprises a support frame bearing a shutter about a hinge provided on its bottom side The axis of the shaft oscillates and is movable between a normally closed position, in which the opening is blocked in a fluid-tight manner, and an open position, which enables smoke and heat to escape through the opening. Operatively associated with the swinging shutter are releasable means for blocking it in the closed position and actuator means for controlling displacement thereof to the open position after release of the blocking means. Background technique [0003] In known fume and heat extraction devices of the type indicated above (an example of which is disclosed in US-4068417), to mana...
