- a clearance is provided between the lever 19 and cam 17 in a position wherein the counter plate 20 engages the solenoid 21, such that upon interruption of the magnetic attraction between both, the torsion spring 18 will allow the lever to achieve a high kinetic energy before engaging the cam 17 on the cylinder. As such a fail proof opening of the locking mechanism is guaranteed.
- the key needs to be introduced into the cylinder and rotated in a direction P2, such that the cam 17 on the cylinder 16a forces the lever back to a position wherein the counter plate contacts the solenoid 21.

- This locking mechanism is particularly suited for use in a smoke evacuation shutter as described above wherein the lock mechanism is preferably mounted in between the exterior panel 6 and the interior panel 7, whereby the locking mechanism can be mounted on the interior panel or on a distance holder 8 close to the interior panel 5, whereby the key hole 10 in the interior panel gives access to the key hole in the cylinder 16a.
- the key when introduced in the cylinder can be turned in a direction P2 beyond its insertion position, whereby the key is prevented from being removed from the key hole by the cover plate 23 such that in this position, the key provides a handle function for closing the door against the force of the torsion springs provided on the hinges of the door assembly. It is noted that when turning the key beyond the insertion position in a direction P2, the cam on the cylinder will engage the lever and push the counter plate 20 against the solenoid 21 against the force of spring 22. As such when releasing the key, it will be forced back to its insertion position for easily removing the key.

Description
- The present invention relates to smoke evacuation shutters having a frame, a door assembly mounted in the frame, and a locking mechanism. Additionally, the present invention relates to a smoke and heat ventilation system using such smoke evacuation shutters.
- In modern fire fighting, the concept of tactical ventilation is commonly used. Tactical ventilation can be described as performing specific venting and fire isolation actions in order to evacuate smoke and heat, to provide firefighters a clear view on the seat of fire, to pull fire away from trapped occupants, and to limit property damage.
- Since in modern buildings, modern materials, especially the polymers, produce a lot more heat than traditional materials (wood, plaster, stone, bricks, etc.), tactical ventilation is even more crucial, such that ventilation systems with dedicated smoke evacuation shutters have been developed and introduced in the buildings.
- Typically, a conventional smoke evacuation shutters as disclosed in eg.
EP0412903 andUS 4054008 , comprise a frame holding a heat resistant panel which is pivoting between an open and closed position in connection to an exhaust air duct, and a locking mechanism for opening manually and/or remotely. - Locking mechanisms for smoke evacuation shutters typically have three operation requirements, namely (i) the lock must be operatable electronically (e.g. by an automated process); and (ii) the lock must be operatable manually. Another important requirement (iii) is that once the shutter has been opened it should be prevented from closing either by itself or by an unauthorized person to ensure correct functioning in case of danger (fire).
- Such locking mechanisms are known in the field of industry and are described in for example
FR 2770613 - Existing smoke evacuation shutters address the above requirement (iv) by providing a grid in front of the door assembly such that one has no access to the lock unless removing the grid. Clearly such solution is non-ideal in that it has severe drawbacks in that it requires removing of the grid for manually operating the locking mechanism for opening said shutter. As for limiting access to the shutter these grids are secured with a plurality of preferably special bolts for which only fire departments or other authorized persons have the tools to unscrew, it is clear that removing the grid is time consuming especially in emergency situations.
- Another requirement (v) of a smoke evacuation shutter is that the air flow through the shutter in open position is as less as possible restricted by the locking mechanism in order to provide an as efficient as possible smoke and heat transport.
- Therefore, it is now an objective of the present invention to provide a smoke evacuation shutter meeting the above requirements without being secured by a grid, such that in case of emergency, authorized person can open the shutter without losing valuable time.
- The present invention meets the above objective by providing a smoke evacuation shutter wherein the locking mechanism is positioned in the door assembly.
- The present invention is directed to a smoke evacuation shutter according to claim 1. Preferred embodiments are covered by the dependent claims.
- Additionally, the present invention is directed to a ventilation system using such smoke evacuation shutters.

-
FIG 1 represents a perspective view of a smoke evacuation shutter according to the present invention; -
FIG 2 represents a cross-sectional view of the smoke evacuation shutter according to the present invention; -
FIG 3 represents a locking mechanism applicable in the smoke evacuation shutter in different positions of said locking mechanism. - Typically a smoke evacuation system of a building comprises air inlet duct and an air exhaust duct that are in fluid connection with the different floors of that building through side ducts, wherein at least in the air exhaust duct means are provided for creating a forced air stream (creating an under pressure in said exhaust duct).
- In said side ducts, smoke evacuation shutters are provided that are closed in a normal position and that - in the event of a fire at a certain floor- open on that floor to evacuate smoke produced by the fire. In this case the smoke evacuation shutters on all other floors of the building are designed to remain closed to prevent smoke entering said floor.
- As represented in
FIG 1 , the smoke evacuation shutter 1 comprises aframe 2 and adoor assembly 3. Theframe 2 can be any known type of frame allowing mounting said door assembly in the concerning side duct or in a hole in a wall in fluid communication with said side duct, whereby the frame engages the wall parts defining the hole or the inner circumference of the duct in an air tight manner. - As represented in
FIG 2 , a smoke evacuation shutter in accordance with the present invention comprises alocking mechanism 25 positioned in the door assembly. By positioning thelocking mechanism 25 in the door assembly instead of at the front side of the door assembly, the locking mechanism itself is not reachable by anyone unauthorized. - Another benefit is that the air flow through the shutter in open position is less (or even not) restricted by the locking mechanism integrated in the door assembly, thereby providing a more efficient smoke and heat transport into the side duct. Consequently, while having the same air flow, the cross-section of the door assembly may be made smaller compared to conventional shutters
- Either, the locking mechanism may be positioned in a recess in a massive panel door assembly, either, in case the door assembly is not made of a massive panel but of a plurality of panels, the locking mechanism may be positioned in between the panels of the door assembly.
- Preferably and as illustrated in
FIG 2 , said lock mechanism is fixed to theinterior panel 7 in between thepanels door assembly 3 and is accessible through akey hole 10 provided in theinterior panel 7 of the shutter 1. - In a particular embodiment, the door assembly has a front facing the room and a back facing the air exhaust duct, wherein the front of the door assembly is planar to the wall. By configuring the shutter such that its front is planar to the wall, in combination with positioning the locking mechanism in the door assembly, opening by unauthorized persons is even more prohibited as it becomes very difficult to force the door assembly by using for example a screwdriver or a pry bar.
- In accordance with the present invention, the smoke evacuation shutter may be configured as an integrated wall module. Such integrated wall module is understood as a kit of parts comprising the frame to be fixed in the wall and puttied up, only leaving pivoting means (e.g. hinges, or pens) uncovered, and a door assembly with integrated locking mechanism to be fixed on the pivoting means.
- In the represented embodiment of
FIG 1 theframe 2 is rectangular and comprises four T-shaped profiles made of a fire resistant material, for example aluminum profiles shielded with a layer of fire resistant material such as calcium silicate. In this case, one of said profiles provided with two pens 5 for a pivoting connection with thedoor assembly 3. - Part of the frame may be configured such that it covers the front contact area of the frame and the door assembly. The
frame 2 may comprise arim 4 covering the slit between the frame and the door assembly at the front side. Such rim is very effective in prohibiting unauthorized persons to force the door assembly by pushing for example a screwdriver between the frame and the door assembly. - It is clear that the door assembly can be realized according several alternatives as long as the locking mechanism can be installed within the door assembly. For example, it may comprise one panel, a plurality of panels, two separate single panel doors being mounted parallel and at a distance of each other, multiple wall saloon type doors, even a roll down panel.
- Preferably, as illustrated in
FIG 2 , the door assembly may comprise a plurality of preferably parallel spaced apartpanels - At least one of said panels, i.e. the
exterior panel 6 that in a mounted and closed position of the smoke evacuation shutter faces the air exhaust duct is preferably manufactured of a heat resistant material. The heat insulating material may, of course, be selected from foamed or non-foamed inorganic heat insulating materials such as glass wool, rock wool, calcium silicate, glass reinforced gypsum, magnesium based materials, perlite and vermiculite. - The interior panel 7 (the panel facing a room of the building in a mounted and closed position of the smoke evacuation shutter) has less stringent heat resistance requirements and can be made out of gypsum or another construction material such as MDF or wood. However this second panel too can be manufactured in for example calcium silicate or other heat resistant materials as exemplified above or synthetic resin materials exemplified by a polyurethane resin material (any one of a hard material, a semi-hard material and a soft material), a denaturated polyisocyanurate resin material exhibiting excellent heat insulating characteristics, a polyethylene resin material, a polystyrene resin material, a urea resin material, a phenol resin material and a polyvinyl chloride resin material. Furthermore, the following heat insulating materials may be employed solely or in a properly combined manner: various rubber materials possessing elasticity such as natural rubber and synthetic rubber.
- In the represented embodiment the door assembly further comprises two torsion spring loaded hinges that are designed to cooperate with the pens 5 in said
frame 2 to pivotably mount the door assembly in the frame such that the door assembly preferably can pivot from a closed to a open position in a direction inwards the side shaft. The hinges force the door assembly to an open position. - In an additional embodiment, a ventilation system is provided using smoke evacuation shutters as described above.
- Applicant also elaborated a new type of
locking mechanism 25 that addresses the above requirements and that can be used in a smoke evacuation shutter as described above. - The
locking mechanism 25 comprises a housing 11 that is preferably made of a heat resistant material such as aluminum or stainless steel defining aguide way 12 guiding aspring 13 actuatedbolt 14. Thebolt 14 comprises aprotrusion 15. - The locking mechanism further comprises a
notch 16 that is rotatably mounted in the housing 11 for opening the locking mechanism. In this case thenotch 16 is part of acylinder 16a that can be actuated by a key and said notch further comprises acam 17 cooperating with aspring 18 loadedlever 19 that at one end is provided with acounter plate 20. As represented in the drawing thecounter plate 20 cooperates with an electrically inducedsolenoid 21 fixed on the housing. Preferably afurther spring 22 is provided between the lever and the counter plate, essentially to force thecounter plate 20 against thesolenoid 21 when in a locked position. - In between the bolt and said lever or the housing is provided the above-mentioned
spring 13 forcing the bolt in a locking direction. - The locking mechanism can be operated in two manners, in a first manual operation, the key is inserted in the
cylinder 16a and can be turned in an unlocking direction P1 in which the notch forces the bolt to retreat into the housing. In this unlocked condition, the key can preferably be retreated from the cylinder by virtue of the design of thelock cover plate 23 and the bolt is forced in a locking position byspring 13. - In a second electronically controlled operation, the solenoid is deactivated such that the magnetic attraction between the
solenoid 21 and thecounter plate 20 is interrupted and thetorsion spring 18 forces thelever 19 to rotate in direction P1. As such thelever 19 will engage thecam 17 provided on thecylinder 16a. Hence the cylinder and itsnotch 16 will rotate thereby engaging the sidewall ofprotrusion 15 in the bolt that as such retreats into the housing (open position of the locking mechanism). It is preferred that a clearance is provided between thelever 19 andcam 17 in a position wherein thecounter plate 20 engages thesolenoid 21, such that upon interruption of the magnetic attraction between both, thetorsion spring 18 will allow the lever to achieve a high kinetic energy before engaging thecam 17 on the cylinder. As such a fail proof opening of the locking mechanism is guaranteed. - To rearm the locking mechanism after electronically controlled operation, the key needs to be introduced into the cylinder and rotated in a direction P2, such that the
cam 17 on thecylinder 16a forces the lever back to a position wherein the counter plate contacts thesolenoid 21. The contact is further improved by virtue ofspring 22 acting on thecounter plate 20. - The described locking mechanism can be applied for smoke evacuation shutters or fire dampers of all kinds, and can be integrated in either the frame or the door assembly. This locking mechanism is particularly suited for use in a smoke evacuation shutter as described above wherein the lock mechanism is preferably mounted in between the
exterior panel 6 and theinterior panel 7, whereby the locking mechanism can be mounted on the interior panel or on a distance holder 8 close to the interior panel 5, whereby thekey hole 10 in the interior panel gives access to the key hole in thecylinder 16a. - In this embodiment, it is preferred that the key when introduced in the cylinder can be turned in a direction P2 beyond its insertion position, whereby the key is prevented from being removed from the key hole by the
cover plate 23 such that in this position, the key provides a handle function for closing the door against the force of the torsion springs provided on the hinges of the door assembly. It is noted that when turning the key beyond the insertion position in a direction P2, the cam on the cylinder will engage the lever and push thecounter plate 20 against thesolenoid 21 against the force ofspring 22. As such when releasing the key, it will be forced back to its insertion position for easily removing the key.
