Brief Introduction to the Drawings
For a better understanding of the invention, and to show how embodiments of the same may be carried into effect, reference will now be made, by way of example, to the accompanying diagrammatic drawings in which: Figure 1 shows a side sectional view of a louvre slat for use in exemplary embodiments; Figure 2A shows a side sectional view of a damper for use in exemplary embodiments; Figure 2B shows a side sectional view of a damper for use in exemplary embodiments; Figure 3 shows a side sectional view of the louvre slat of Figure 1 and sections of dampers as shown in Figure 2A arranged in a louvre assembly according to an exemplary embodiment; Figure 4 shows a side sectional view of a louvre assembly according to an exemplary embodiment, with dampers moved to a closed position Figures 5A-5C show side sectional views of a portion of the louvre assembly of Figure 4 with the dampers moving toward an open position; Figure 6 shows a side section view of a louvre assembly according to an exemplary embodiment, with dampers moved to an open position; and Figures 7 and 8 show side sectional views of louvre assemblies according to other exemplary embodiments.
Description of Preferred Embodiments
Figure 1 shows a side sectional view of a louvre slat 1 for use in a louvre assembly according to an exemplary embodiment. The louvre slat 1 is fixed in use arranged across an opening, for example as part or an array of identical slats to form part of a louvre assembly. The louvre slat I is, aside from at its ends, of generally constant cross section across its width. On its ends the louvre slat 1 has fixer portions 11 used to hold the louvre slat 1 in place relative to an opening, for example by having screws, bolts, rivets or other fasteners cooperating with them. The opening may form part of a frame for a louvre assembly, the frame being then mounted in situ as one piece with the rest of the louvre assembly, or the louvre slat may be held directly in situ at the opening where the complete louvre assembly is to be assembled. Also shown in Figure 1 is sealing element 12 which will be described in more detail with reference to Figures 3 and 4 below, and a male part 13 of a mounting that is used to couple the louvre slat 1 to a damper.
Figure 2A shows a side section view of a damper 2 for use in a louvre assembly according to an exemplary embodiment, for example in combination with the louvre slat 1 of Figure 1. The damper 2 comprises a female part 23 of the mounting that is used to couple the damper 2 to a louvre slat. The damper of Figure 2A comprises a thermal insulation material 21 surrounded by a sealed layer or skin of waterproof material. This construction enables an air-carrying or open-cell type insulation material to be used without degradation in performance due to damp ingress. Figure 2B shows an alternate damper construction in which the female part 23 of the mount is formed on an end cap 24 which is used to carry a piece of thermal insulation material 21.
The male and female parts 13, 23 of the mounting can be coupled by sliding one into the other along their length, or in other embodiments by an interference or snap-fit arrangement. Once the male and female parts 13, 23 of the mounting are coupled the louvre assembly shown in Figure 3 is formed.
The exemplary embodiment of Figure 3 shows one louvre slat 1 coupled to one damper 2 above the louvre slat 1. The exemplary embodiment of Figure 3 also shows a second damper 2, which is suitably coupled to a second, lower, louvre slat that is not shown. Figure 3 also shows an actuator attachment portion 25 which is used to couple the damper 2 to an actuator such that operation of the actuator is arranged to move the damper between open and closed positions.
The way in which a plurality of louvre slats 1 and dampers 2 can work together in a louvre assembly is further understood with reference to Figure 4. It will be appreciated that louvre assembly 30 will have at its upper and lower extremities a degree of adaptation so that the extremities can work effectively at the boundary of the opening which the louvre assembly 30 is to occupy.
As can be seen in Figure 4, the louvre assembly 30 comprises a plurality of louvre slats 1 which are similar to one another and which are arranged in generally parallel alignment with one another in a regularly spaced array. The angles and dimensions of the surfaces of the louvre slats 1 is chosen according to the design requirements for shielding of the opening in which the louvre assembly is to be situated. The louvre assembly 30 comprises a plurality of dampers, and for the portion of the assembly away from the extremities each louvre slat 1 has a damper arranged between adjacent louvre slats.
The dampers 2 are coupled by their actuator attachment portions 25 to an actuator, which is arranged to move the dampers in unison between open and closed positions. Figure 6 shows a louvre assembly in which the dampers 2 have been moved to an open position using an actuator bar 26 coupled to the actuator attachment portions 25. In this embodiment all of the dampers 2 are moved together under the influence of a single actuator coupled to the actuator bar 26, but it will be appreciated that in other embodiments two or more groups of dampers 2, for example groups made up of alternate dampers 2 or by dividing along the extent of the louvre assembly may be moved independently of one another..
The louvre assembly 30 is arranged such that movement of the dampers 2, by an actuator in the range between the closed position shown in Figure 3 and an open position in which a passageway is formed across the louvre slats I and the dampers 2 varies the extent of the opening provided by the passageway, and therefore the amount of ventilation provided by the louvre. An outer passageway portion between adjacent louvre slats I is not changed but an inner passageway portion between adjacent dampers 2, when the dampers are arranged in the closed position is changed by movement of the dampers 2 between a fully open position in which the dampers 2 are generally parallel to the angled surfaces of the louvre slats 1 and the a fully closed position as shown in Figure 3 in which the dampers 2 fill the space between the louvre slats 1 to close the inner passageway portion. Figure 6 as mentioned above shows the fully open position, and Figures SA-5C show intermediate positions as the dampers 2 are moving from the fully closed position to the fully open position.
The mounting between the louvre slats 1 and the dampers 2 defines a fixed rotational axis for the damper relative to the louvre slat. The axis is provided by a hinge at an edge region of the louvre slat and made up of the male and female parts 13, 23. The channel which makes up the female part 23 and the bead which makes up the male part 13 are of complementary cross section so as to provide a gap-free hinge that remains gap-free throughout the range of the hinge action. This prevents drafts though the hinge and therefore improves the thermal insulation performance of the louvre assembly 30 when the dampers 2 are in the closed position. In other embodiments a flexible web can be provided running between the louvre slats and the dampers to prevent drafts. The sealing element 12 is also arranged to prevent drafts when the dampers 2 are in the closed position by providing a generally air-tight seal therebetween when arranged in the closed position.
In some embodiments the dampers 2 are arranged such that they too are sealed against one another when arranged in the closed position. This may involve movement of adjacent dampers separately or provision of compressible end portions to bring about the sealing between dampers while maintaining the operational ability of the dampers to move between the open and closed positions.
In the embodiments described above the end portions of the dampers are shaped so that adjacent dampers do not interfere with one another as the dampers move between positions. The end portions of the dampers are arranged so that their surfaces are in close proximity when in the closed position, and so that the surfaces move across one another without fouling as the dampers open and close.
Figure 7 shows a louvre assembly 30' according to another exemplary embodiment, but with modifications to the mounting, sealing element and damper shape. In this embodiment like elements to those described above are identified with the corresponding primed reference numerals. Figure 8A shows a louvre assembly 30" according to another exemplary embodiment, but with modifications to the mounting, sealing element and damper shape. In this embodiment the front and rear surfaces of the damper are provided with a piece of thermally insulating material M between them. In this way, heat transfer across the damper by conduction through the skin thereof is reduced. Figure 8B shows this assembly built up, in closed and open positions respectively. In this embodiment like elements to those described above are identified with the corresponding double primed reference numerals.
Separation of the louvre assembly's functionality between the louvre slats and the dampers means that the louvre slats can be made of relatively cheap materials (with required characteristics such as strength and degree of transparency) while the dampers and the associated draft-proofing seals can give good thermal properties without the need for complicated fixings and supports. The dampers are protected from rain ingress but can still be positioned to give good ventilation, and the actuator arrangements useful with the assemblies described herein are of simple construction.
