Abstract

A device includes a remotely controllable smoke extractor fan in combination with a remotely controllable actuator. The actuator is operable in use to open or close an aperture. The aperture may comprise a window or door aperture, wherein the actuator is an L-shaped lever 10 that moves a window or door in order to open or close the aperture. The extractor fan and actuator may be operated in response to signals received from a smoke detector or a remote control. The actuator may also be operated in response to a signal received from a rain sensor. Following detection of a fire by the smoke detector, the device may simultaneously open the aperture and operate the extractor fan in order to ensure that smoke is rapidly expelled and thereby reducing the risk of smoke inhalation. The device may include a removable protective casing 11.

Description

DESCRIPTION
THE HINGING SASH ACTUATING SMOKE EXTRACTOR
This is an electrically powered extractor fan combined with a sash operating mechanism which opens or closes the hinging member of a window, door, or other aperture when adjacently attached to the static frame (see fig. 1). The hinging opener mechanism & extractor fan operate automatically with an electrical power supply controlled by a variety of different types of electrical switching at remote or separate positions.
The extractor fan may be turned on simultaneously as the window is opened by the signal received from one or more smoke detectors. This offers rapid protection from smoke inhalation to the occupants of habitable space usually ventilated by windows commonly installed in roof slopes. Unless smoke is being extracted by the fan, a rain sensor may also cause the window to close automatically, when the fan may be remotely controlled merely to circulate air.
The preferred window operating mechanism comprises a base plate (1) retaining a removable protective casing (Figure 1 no.11) which provides anchorage for the essential components being the cross flow tangential fan (20) mounted on top of the window actuating mechanism. Unless another type of mechanism is fitted, such as the push pull electric chain actuator in established use, this comprises the L shaped cranked sash operating lever (herein termed the crank') driven by an electrically powered linear actuator (15) describes a quadrant arc in connection with a linear slide (13) attached to the opening sash. The crank (10) is mounted on a spindle bolt (7) attached in an upright position to the base plate.
Rotation at this fulcrum is made by a spherical plane bearing (9) driven into the crank's corner drilling, which also allows for slight changes in its rotational axis. The shorter crank leg is driven by an articulating pin linkage (14) connected with the fork ended moving member of the tubular electric linear actuator. The linear actuator's opposing end is anchored within a spherical plane bearing (8) contained by a housing (2) attached in an upright position to the far end of the base plate (1).
Whilst the crank's shorter leg is driven by the linear actuator, the crank's long leg (see fig. 2) moves through an arc out of the casing slot provided (see figs. 2 & 9) from a position folded within the casing (11), to its fully extended perpendicular position to the sash. Further movement is prevented by electrical limit switches within the linear actuator at both ends of its travel. The arc' s radius described by the longer crank leg is synonymous with the sash's maximum opening distance.
DESCRIPTION
The anchored end of the linear actuator incorporates a spring loaded buffer assembly. This comprises a compression spring (17) sleeved over the actuator's end shaft, part loaded in tension between the actuator's body end face and the spherical plain bearing (8). Resistance in the sash closing movement is opposed by the compression spring causing the actuator end shaft to push back a nominal distance through the spherical plane bearing, in which it may loosely slide back and forth. A roll pin and washer on the actuator end shaft behind the spherical plane bearing housing retain the assembly in compression. The effect of the assembly described is to absorb increased resistance periodically encountered by the closing movement, whilst also adding a mechanical incentive to the beginning of the opening movement.
