Description
WINDOW OR DOOR VENTILATION DEVICE
The present invention relates to a ventilation device and, in particular, to a ventilation device for installation above the glass panel of a door or a window.
Ventilation devices for installation above the glass panels of doors and windows have been proposed in which an air inlet is situated to the outside of the window or door with appropriate shielding from the rain, and an air outlet is situated to the inside of the window or door, the passage connecting the air inlet and the air outlet together having mounted therein means to control the flow of air therethrough.
Examples of such ventilation devices are disclosed in
GB-A-2156967, GB-A-2224826, EP-A-0327186, EP-A-0429322 and W093/09237.
We have now developed an improved ventilation device for installation above the glass panels of doors and windows which can be opened and closed in a very easy manner and which incorporates a damper against which, in the closed position, the incoming air will apply a pressure, thereby preventing the damper from opening accidentally.
Accordingly, the present invention provides a window or door comprising at least one glass panel having a ventilation device mounted thereabove, the ventilation device comprising a housing mounted over the glass panel of the door or window, the housing having an air inlet situated at the outer side thereof and an air outlet situated at the inner side thereof, the air inlet and the air outlet being connected by means of an air passageway, a pivoted damper being located in the air passageway adjacent the air outlet, the damper being operable by means of an actuating mechanism from a closed position in which the damper closes the air outlet by bearing against an interior surface of the air outlet which faces the air passageway, and one or more open positions, the damper being of arcuate section, and the ventilation device being provided with means for biasing the damper in the closed and the open positions.
The window or door in which the ventilation device is mounted may be single, double or triple glazed. It will be understood that the dimensions of the housing forming part of the ventilation device will then be made of appropriate dimensions so that the housing can be mounted above the glass panel or panels of the window or door. The operation of the ventilation device is the same, regardless of the width of the window or door above which the device is mounted.
The housing and the damper of the ventilation device may be moulded from a synthetic plastics material, such as polyvinyl chloride, or from extruded aluminum. In this manner the component parts of the ventilation device may be cut to an appropriate length, depending upon the width of the window or door over which the ventilation device is to be mounted.
The biasing means of the ventilation device, which biases the damper in the open and the closed positions in one preferred embodiment of the invention is an overcentred spring, one end of the spring engaging appropriate means on the damper and the other end engaging appropriate means on the housing.
Preferably the spring comprises an arcuate element formed from a resilient material such as acetal resin, a polymer, a metal or an alloy. The spring may be mounted in position by one end engaging a pin formed in an end vertical wall of the housing and the other end having a protruding rod or pin attached thereto which is located in an appropriate aperture, for example a longitudinally extending channel, formed in the damper. The spring serves to bias the damper into both the closed and the open positions and, as the damper moves from one position to the other, the spring will pass through a dead centre position.
Preferably a spring will be provided at each end of the damper in order to assist the operation of the damper within the ventilation unit.
The damper preferably has an integrally formed actuating mechanism which serves as a lever to open and close the damper. The damper is of arcuate section, the curved face ensuring that there is a good airflow over all of the faces of the damper when the damper is in its open position.
The damper is pivoted adjacent the air outlet, preferably pivoting around the longitudinal lower edge of the air outlet, for example by pivoting around a longitudinally extending bar forming the said lower edge. In its closed position the damper preferably closes the air outlet by bearing against the upper interior longitudinally extending surface of the air outlet. Preferably a seal is provided along the upper longitudinal edge of the damper, for example a neoprene seal which may be located in an appropriate longitudinal groove or channel formed in the damper, or if the damper is formed from a suitable material the seal may be integrally formed therein.The closure of the damper to the interior of the housing of the ventilation device is advantageous in that air entering the passageway through the housing will apply pressure to the damper and, in particular, will assist in maintaining the damper in the closed position and avoid the damper being blown open accidentally. Thus, an increasing static pressure wind will close the damper assembly more securely in contrast to many devices in which the ventilator damper seals to the exterior of the air outlet, with increasing air pressure thereby encouraging the damper to open.
The air inlet to the ventilation device will preferably be provided with an outer hood which will prevent rain, sleet or snow from ingressing into the device.
The present invention will be further described with reference to the accompanying drawings in which:
Figure 1 illustrates a cross-section of a first ventilation device of the present invention in its closed position,
Figure 2 illustrates a cross-section of the ventilation device of Figure 1 in its open position,
Figure 3 illustrates a cross-section of a second ventilation device of the present invention in its closed position,
Figure 4 illustrates a cross-section of the ventilation device of Figure 3 in a position lying between the fully open and closed positions, and
Figure 5 illustrates a cross-section of the ventilation device of Figure 3 in its fully open position.
Referring to Figures 1 and 2 of the drawings, a cross-section of a double glazed window is shown generally at 1. The over window ventilation device of the present invention is shown generally at 2 and comprises a housing 3 having an air inlet 4 and an air outlet 5 (see Figure 2). The air inlet 4 comprises a plurality of slots through which the air passes. The air inlet is protected from rain, sleet and snow by means of the outer hood 6 which is adapted to slide over the housing 3 by means of the U-shaped section 7 of the hood 6 engaging the upstand 8 of the housing 3 and by means of a projection 9 on the hood 6 engaging a corresponding groove 10 on the housing 3.
If desired, an insect screen can be provided as a screen or mesh covering the slots of the air inlet.
A damper 11 is located in the air outlet, the damper 11 being pivoted around longitudinal bar 12 which forms the lower edge of the air outlet. The damper 11 has an integrally formed actuating mechanism 13 and the combined damper and actuator are of an arcuate section as illustrated. The damper 11 is provided along its upper edge with a bead 14 which locates in an arcuate channel 15. The bead 14 seals against the interior surface 16 of the air outlet when the damper is closed.
A resilient spring member 20 is provided which serves to bias the damper into the closed position in
Figure 1 and the open position in Figure 2. The spring member comprises an arcuate section 21 which is connected at one end by means of a protruding rod or pin 22 locating in a channel 23 of appropriate diameter formed in the damper 11. The other end of the spring member 20 engages a pin 24 formed in a vertical end face 25 of the housing 3.
As can be seen from Figures 1 and 2, upward movement of the actuating mechanism 13 causes the damper 11 to move from the closed to the open position. When the damper 11 is in the open position, the spring 20 in a section in close proximity to the pin 22 abuts with a recess 26 formed in the vertical end face 25 of the housing 3. The spring 20 serves to bias the damper into both the closed and the open positions and as the damper moves from one position to the other the spring passes through a dead centre position.
In Figure 2 of the drawings the passage of air from the outside of the window to the inside of the window is shown by the arrows.
Referring now to Figures 3, 4 and 5, a second ventilation device of the present invention is illustrated where numerals which are the same as those used in Figures 1 and 2 relate to common features.
A resilient spring member 20 is provided which serves to bias the damper 11 into the closed position in Figure 3, a position lying between the fully open and closed positions in Figure 4, and the fully open position in Figure 5.
The spring member 20 comprises a resiliently biased member having detent means 30 and 31 formed therein, which interact with the channel 15 of damper 11, thereby releasably locating the damper 11 in the closed and open positions; the open positions including positions lying between the fully open and closed positions.
The spring member 20 is anchored to vertical end face 25 of the housing. Anchorage means are provided by pins 32 and 33, which engage in complementary holes (not shown) formed in the spring member 20 and the vertical end face 25. It will be understood, however, that the anchorage means may comprise just one pin or more than two pins, where appropriate. It will further be understood that anchorage means may be provided by a variety of other fastenings, such as rivets, welds, adhesives or combinations thereof.
In the closed position, Figure 3, the interior surface 16 of the air outlet 5 (see Figure 4) abuts with the bead 14, and the channel 15 of the damper 11 interacts with a detent means 30, which is a rigid protuberance integrally formed in the spring member 20, thereby releasably locating the damper 11 in the closed position.
On application of sufficient force to the actuating mechanism 13, the spring member 20 flexes, predominantly in a section lying between the anchorage point 32 and the detent means 31, thereby allowing the channel 15 to ride over the detent means 30.
The damper 11 continues to pivot around longitudinal bar 12, thereby further opening the ventilation device 2, until the movement of the damper 11 is arrested when channel 15 interacts with a relatively rigid detent means 31, which comprises a bent arm integrally formed with the spring member 20 and extending therefrom. The detent means 31, in combination with the detent means 30, serves to releasably locate the damper 11 in a position lying between the fully open and closed positions.
Again, upon application of sufficient force to the actuating mechanism 13, the spring member 20 flexes, predominantly in a section lying between the anchorage point 32 and the detent means 31, thereby allowing the channel 15 to ride over detent means 31.
The damper 11 continues to pivot around longitudinal bar 12, thereby further opening the ventilation device 2, until the movement of the damper 11 is terminated when channel 23 abuts with a ridge 34 formed in the vertical face 25 of the housing 3. The damper 11 is now biased in the fully open position and releasably located there by virtue of the detent means 31.
It will be understood that the spring member 20 may be provided with just one detent means, serving to releasably locate damper 11 in either the closed or fully open positions. It will also be understood that the spring member 20 may be provided with more than two detent means, serving to releasably locate the damper 11 in a multiplicity of positions lying between fully open and closed positions.
It will further be understood that the detent means of the spring member 20 may consist of protuberances, ridges, arms or combinations thereof.
For the first and second ventilation devices of the present invention it will be understood that a spring will preferably be provided at each end of the damper 11 in order to assist the operation of the damper 11 within the ventilation unit 2. The spring 20, or each spring, is preferably moulded from a resilient material such as acetal resin, a polymer, a metal or an alloy.
One advantage of the ventilator of the present invention is that the damper 11 seals to the inside top edge of the air outlet 5. Accordingly, when the damper is closed any air flowing through the air inlet 4 of the housing will assist in keeping the damper in its closed position.
An advantage of the second ventilation device of the present invention is that the damper 11 can be reliably releasably located in a variety of positions with respect to the housing 3, including positions lying between the fully open and closed positions.
Referring to Figure 6 of the accompanying drawings, the benefits of a damper 11 with an arcuate section are illustrated. The damper 11 pivots around longitudinal bar 12 which forms the lower edge of the air outlet. The damper has an integrally formed actuator mechanism 13 as described with reference to
Figure 1. The damper is shown in its open position.
In the open position the arcuate form of the damper ensures that the damper is at the same distance A from different points of the air passageway, thus ensuring an even flow of air. If the damper were not of arcuate form then the angle of rotation of the damper would need to be greater in order to achieve the same "A' dimension.
The dimension "H" shown on the drawing is required to be a maximum when the damper is in the open position in order to minimise the risk of carry through of water in rainy conditions. An increase in the angle of rotation for a non-arcuate damper would decrease the height "H" which clearly would not be favoured.
The component parts of the ventilation device of the present invention may be moulded from a synthetic plastics material, such as polyvinyl chloride, or from extruded aluminium.
Generally only one damper will be provided within the housing but it will be understood that the ventilation device of the present invention may be fabricated, if desired, with a plurality of individual dampers. This may be advantageous if the window or door over which the ventilation device is mounted is very long since it provides a wider degree of control of the ventilation to the room.
