    ADJUSTABLE VALVE
    TECHNICAL DOMAIN
    The invention relates to an adjustable valve for an air duct for forced or unforced ventilation of a home and the like.
    BACKGROUND ART
    An air valve is used to control the supply or removal of air in a room. Usually an air valve is placed in a wall or ceiling of the relevant room. An adjustable valve is an air valve in which the passage of air can be adjusted. This is achieved by adjusting or adjusting the structural components of an adjustable valve. Such adjustable valves are known from the prior art. US 5 133 693 describes an air supply and discharge valve that provides a convenient and manual adjustment of the air flow therethrough. The device according to US 5 133 693 comprises an outer and an inner housing, each with a tubular part and a radially extending flange. The inner tubular member is axially adjustable within the outer housing, which adjustment is accompanied by friction, in order to control the air gap between the two flanges. The inner tubular part is provided with a cover element. US 5 133 693 has the problem that the positioning of the cover element depends on the position of the inner tubular part. This provides limited flexibility with regard to the adjustment of the components of the valve. NL 1 008 230 describes an air valve for a suction channel for mechanical or natural ventilation of a house and the like, comprising a cover edge, a substantially pipe-shaped part connecting thereto and an adjustable part for forming an adjustable extraction gap. According to 1 008 230, the adjustable portion is arranged at the rear edge of the tubular portion.
    The positioning of the adjustable part at the valve of NL 1 008 230 ensures a complicated construction of the valve. In addition, it requires some effort to adjust the valve. The increased efforts in both production and installation are problematic for the efficient and smooth provision of such air valves.
    It is an object of the present invention to find a solution to at least some of the aforementioned problems.
    SUMMARY OF THE INVENTION
    A first aspect of the present invention relates to an adjustable valve 1 for an air duct for forced or unforced ventilation of a house and the like, comprising a housing 2, a cover element 7 and an adjustable valve 5 positioned between them, the housing 2 comprising a first housing side 23 which is adapted to be connected to said air duct and a second housing side 24, opposite the first housing side 23, which is adapted to receive said valve 5, wherein the cover element 7 is manually adjustable relative to the valve 5 via axial translation and the housing 2.
    The adjustment of the cover element 7 by means of axial translation is intuitive, user-friendly and simple to implement. In addition, this setting makes it possible to bring the cover element 7 at various distances from the valve 5 and the housing 2. This is advantageous for controlling the air flow rate and / or the direction of outflow of air in a room, and is also useful for maintenance work on the adjustable valve 1.
    A second aspect of the present invention relates to a method for manufacturing an adjustable valve 1 for an air duct for forced or unforced ventilation of a home and the like, the adjustable valve 1 comprising a housing 2, an adjustable valve 5 and a cover element 7, the method comprising the steps of: - providing a housing 2; - providing a valve 5; - providing a cover element 7; - coaxially placing housing 2, valve 5 and cover element 7, wherein the valve 5 is placed between housing 2 and cover element 7; wherein in one step the housing 2 is provided with one or more spacer members 8.
    The provision of spacer members 8 provides a simple and efficient adjustment of the cover element 7. By physically bringing the cover element 7 into contact with the spacer members 8, a constant distance between cover element 7 and housing 2 is obtained simply and independently of the position of the valve 5.
    A third aspect of the present invention relates to a use of a method according to the second aspect of the invention for manufacturing an adjustable valve 1 according to the first aspect of the invention.

    DETAILED DESCRIPTION
    A first aspect of the present invention relates to an adjustable valve 1 for an air duct for forced or unforced ventilation of a house and the like, comprising a housing 2, a cover element 7 and an adjustable valve 5 positioned between them, the housing 2 comprising a first housing side 23 which is adapted to be connected to said air duct and a second housing side 24, opposite the first housing side 23, which is adapted to receive said valve 5, wherein the cover element 7 is manually adjustable relative to the valve 5 via axial translation and the housing 2.
    An adjustable valve 1 is typically placed in a wall, ceiling, or similar structural part of a room. In an atypical arrangement, however, it is possible to freely position the controllable valve 1 in the space, as would be the case, for example, when an air duct was penetrated into a space. An adjustable valve 1 is placed at one end of an air duct that forms part of an aeration system for forced or unforced ventilation of a home and the like. By adjusting or adjusting structural components of an adjustable valve 1, the flow or flow of air supplied or discharged through the air duct can be controlled. The flow can practically be controlled by increasing or decreasing the opening or gap of the adjustable valve 1, through which air can be moved. The cover element 7 functions on the one hand as a device for deflecting air and on the other hand for the visual and aesthetic finish of the adjustable valve 1, in order to obtain a desired integration thereof into the interior of a room. Casual ventilation can be seen as guiding a natural air flow through ventilation system, air duct and adjustable valve 1. With forced ventilation, the supply or removal of air is promoted with the aid of a mechanical drive means such as a fan. Examples of possible embodiments of an adjustable valve 1 according to the present invention are shown in FIG. 1a, FIG. 1b, FIG. 2a and FIG. 2b. The housing 2 is constructed from a cylindrical housing 3 on which, facing the valve 5, an enlarged first collar 4 is present. The first collar 4 functions to make a nice connection with the surface of the wall, ceiling, or similar construction in which the adjustable valve 1 is placed. The first collar 4 provides a covering of the cavity in the wall, ceiling or similar construction in which the adjustable valve 1 is placed, so that any inaccuracies or damage at the height of the edge of this cavity are covered. The design of the cylindrical housing 3, at least for said first housing side 23, is preferably adapted to the dimensions of an air duct with which it is desired to connect the adjustable valve 1. The remainder of the cylindrical housing 3 can take any shape, but the interior of the cylindrical housing 3 is preferably adapted to the dimensions of the valve 5. A detail of possible embodiments of the housing 2 is shown in FIG. 4a, FIG. 4b, FIG. 5a and FIG. 5b. A valve 5 is present on the second housing side 24 of the housing 5. This valve 5 is adjustable, which means that the distance between valve 5, housing 2 and cover element 7 can be adjusted. The valve 5 is preferably adjustable by axial translation. A preferred embodiment of the valve 5, a possible embodiment of which is shown in detail in FIG. 3a and FIG. 3b shows a substantially conical body with an enlarged second collar 6 remote from the housing 2 and facing the cover element 7. In principle, the valve 5 can take any shape as long as the valve 5 is adjustable relative to the housing 2 so that the gap between valve 5 and housing 2 can be varied. Preferably, however, the valve 5 is designed such that the valve 5 can close the opening of the housing 2 on the second housing side 24 in an extreme approximation between valve 5 and housing 2 if desired. The second collar 6 and its transition into the rest of the body of the valve 5 ensures a streamlining of the valve 5, so that an optimum flow can be obtained and so that noise caused by air flowing past it is maximally avoided. The inside of the valve 5 facing the cover element 7 is furthermore provided with substantially radially oriented ribs 22. These ribs 22 ensure a further streamlining of air flowing along it. Cover element 7, valve 5 and housing 2 can be made of any suitable materials, as known from the prior art.
    The adjustment of the cover element 7 by means of axial translation is intuitive, user-friendly and simple to implement. In addition, this setting makes it possible to bring the cover element 7 at various distances from the valve 5 and the housing 2. This is advantageous for controlling the air flow rate and / or the direction of outflow of air into a room, and is also useful for maintenance work of the adjustable valve 1. On the aesthetic level it may namely be desirable that the cover element 7, which largely determines the visually perceptible part of the controllable valve 1 always takes the same position with respect to a wall, ceiling or similar construction in which the controllable valve 1 is placed. In addition, it may be desirable, such as for example during maintenance work, to briefly increase the distance between the cover element 7 on the one hand and housing 2 and valve 5 on the other hand in a convenient manner.
    The manual adjustment of the cover element 7 relative to the valve 5 and the housing 2 by means of axial translation is not obvious for two reasons. Firstly, it is inventive to enable the adjustability of the cover element 7 relative to both valve 5 and housing 2, instead of connecting the cover element 7 non-adjustably to valve 5 or housing 2. Secondly, an adjustment via axial translation allows a simple and intuitive quantification of the adjustment. The number of rotations of the cover element 7 can thus be associated with a certain degree of adjustment.
    In a preferred embodiment, the present invention provides an adjustable valve 1 according to the first aspect of the invention, wherein the housing 2 is provided with one or more spacer members 8.
    The term "spacers" 8, as used in this text, refers to elements that are provided on the housing 2 and that act as a barrier against the approach of a cover element 7 to the housing 2. To that end, at least a portion of said spacers increases 8 the volume of the housing 2 in the direction of a cover element 7 to be placed or placed. With the aid of the spacer members 8, the distance of the cover element 7 from the housing 2 can simply be standardized. Preferably, said spacer members 8 do not prevent the approach of said valve 5 with respect to the housing 2, since this would hinder the setting of the flow rate of transported air. The spacer members 8 can be releasably or releasably connected to the housing 2. A releasable connection has the advantage that the spacer members 8 can be removed from the housing 2 if desired, which is advantageous as a space-saving measure when transporting an adjustable valve 1 according to the present invention. In one embodiment, one spacer member 8 is placed on the housing 2, and this spacer member 8 is designed as an edge extending the housing 2 on the second housing side 24 in the direction of a cover element 7 to be placed or a placed cover element 7. In a preferred embodiment one or more discrete shapes are placed at a distance from each other on the housing 2, these discrete shapes extending the housing 2 on the second housing side 24 in the direction of a cover element 7 to be placed or a placed cover element. geometric bodies are understood, such as for example cubes, beams, pyramids, cylinders, or, in addition, also understood to be totally randomly shaped bodies. Placing discrete shapes has the advantage over the said edge that the amount of material necessary for the spacers 8 can be considerably limited.
    An example of a possible embodiment of a housing 2 with spacers 8 is shown in FIG. 1b, FIG. 2b, FIG. 4a and FIG. 5a. The spacer members 8 are designed as substantially cylindrical shapes that are spaced apart on the first collar 4. The cylindrical shapes are positioned such that they limit the approximation of a cover element 7 with respect to the housing 2, while the spacers 8 do not hinder the movement of the valve 5 relative to the housing 2.
    The spacer members 8 ensure that the cover element 7, when approaching the housing 2, will always come to the same distance relative to the housing 2. This positioning of the cover element 7, independently of the setting of the valve 5, contributes to a simple maintenance of the adjustable valve 1, without the need for intensive maintenance of the valve 5 for adjusting the flow rate during each maintenance. With a constant distance between cover element 7 and housing 2, after all, only the specific positioning of the valve 5 relative to the housing 2 will have to be taken into account for setting the flow.
    The provision of the spacer members 8 on the housing 2 to standardize the positioning of said cover element 7 is remarkable. After all, a person skilled in the relevant field of the prior art would, from his gut feeling, opt to connect the cover element 7 to the valve 5. However, this would entail the disadvantage that during maintenance or cleaning of the cover element 7, the positioning of the valve 5 can already be disrupted quickly, which can lead to additional efforts for adjusting the flow.
    In a preferred embodiment, the present invention provides an adjustable valve 1 according to the first aspect of the invention, wherein said housing 2, valve 5 and cover element 7 can be coaxially mounted about a central axis 9. In another preferred embodiment, housing 2, valve 5 and cover element 7 coaxially mounted around said central axis 9.
    Bearing both housing 2, valve 5 and cover element 7 around a single axis 9 is a material-efficient and intuitive solution to enable the adjustment or adjustment of valve 5 and cover element 7 via axial translation.
    An example of a possible embodiment thereof is shown in the exploded drawings of FIG. 1a, FIG. 1b, FIG. 2a and FIG. 2b. In the example shown, said central shaft 9 is designed as a cylindrical shaft provided with an external screw thread. The central shaft 9 can be made of a metal, an alloy of metal, or of a plastic. The housing 2 has a central opening 15 for receiving the central shaft 9. The valve also has a central opening 16 for receiving the central shaft 9. The cover element 7 is provided with a sleeve 17 for receiving said central shaft. central shaft 9. In the example a wing nut 20 is provided between cover element 7 and valve 5, which wing nut 20 can be used to additionally fix the position of the valve 5.
    In a preferred embodiment, the present invention provides an adjustable valve 1 according to the first aspect of the invention, wherein said spacers 8 are symmetrically disposed about said central axis 9.
    A possible embodiment of a symmetrical arrangement of spacer members 8 around said central axis 9 is clearly shown in FIG. 1b and FIG. 2b.
    A symmetrical placement of the spacer members 8 around said central axis 9 ensures uniform contact between the spacer members 8 and the surface of said cover member 7. This is important for uniform adjustment of the cover member 7.
    In a preferred embodiment, the present invention provides an adjustable valve 1 according to the first aspect of the invention, wherein said cover element 7 comprises a metal, while said housing 2 and valve 5 comprise a plastic.
    With a placed adjustable valve 1, the cover element 7 is visible from the space in which the adjustable valve 1 is placed. An embodiment of the cover element 7 in metal is aesthetically preferable to a cover element 7 of plastic. Non-limiting examples of suitable metals are iron, aluminum, copper, chromium, nickel, lead, zinc, tin and platinum. In a preferred embodiment, aluminum is selected as the metal. In addition, alloys of metal, such as for example steel, are also suitable for the cover element 7. Housing 2 and valve 5, on the other hand, are preferably provided in a plastic because of the greater flexibility and possibilities in terms of design. In addition, a considerable cost saving can be obtained by using a plastic for housing 2 and valve 5 instead of a metal. Non-limiting examples of suitable plastics are acrylonitrile-butadiene-styrene, epoxy resins, high-density or low-density polyethylene, polycarbonate, polymethyl methacrylate, polypropylene, polystyrene, polyurethane and polyvinyl chloride. In a preferred embodiment, a polypropylene compound is selected as plastic. The plastic can be further reinforced with fibers if desired.
    In a preferred embodiment, the present invention provides an adjustable valve 1 according to the first aspect of the invention, wherein said cover element 7 comprises aluminum, steel, a galvanized steel or stainless steel. Steel is easily available. Aluminum hardly corrodes, and galvanized steel or stainless steel are corrosion resistant. By selecting aluminum, galvanized steel or stainless steel for said cover element 7, corrosion of the cover element 7 is avoided, whereby structural weakening and aesthetic depreciation of the cover element 7 are avoided.
    In a preferred embodiment, the present invention provides an adjustable valve 1 according to the first aspect of the invention, wherein a connecting flange 10 for engaging said air duct is included at the periphery of the housing 2 on said first housing side 23.
    The connecting flange ensures an airtight connection between adjustable valve 1 and an air duct. The connecting flange is preferably made from a plastic. More preferably, the connecting flange comprises a thermoplastic elastomer, such as, for example, a thermoplastic polyolefin.
    The connecting flange is preferably designed as a double lip seal. Such a double lip seal has the advantage that a double certainty against air leakage is achieved, so that an optimally airtight connection between adjustable valve 1 and air duct can be obtained. An example of a possible embodiment of an adjustable valve 1 with a double lip seal is shown in FIG. 1a, FIG. 1b, FIG. 2a, FIG. 2b, FIG. 4a, FIG. 4b, FIG. 5a and FIG. 5b.
    In a preferred embodiment, the present invention provides an adjustable valve 1 according to the first aspect of the invention, wherein one or more engaging means 11, 12 for engaging the adjustable valve 1 on a ceiling, wall or similar construction are included on the periphery of the housing 2.
    The positioning of the engaging means 11, 12 provides for a simple, fast and stable mounting of an adjustable valve 1 in a ceiling, wall or similar construction.
    In one embodiment the engaging means are provided as protrusions 11. These are adapted to grip onto a mounting ring 13 which is arranged in a ceiling, wall or similar construction. An example of a possible embodiment thereof can be seen in FIG. 1a, FIG. 1b and FIG. 5b. As illustrated, the mounting ring 13 itself can be connected by screws 18 provided in recesses 19 of the mounting ring 13 to a ceiling, wall or similar construction.
    In another embodiment, the engaging means are provided as jumping wings or mounting springs 12. Such mounting springs 12 are adapted to grip in a cavity arranged in a ceiling, wall or similar construction. An example of a possible embodiment of a housing 2 with said mounting springs 12 is shown in FIG. 5a and FIG. 5b.
    In a preferred embodiment, the present invention provides an adjustable valve 1 according to the first aspect of the invention, wherein said engagement means 11, 12 are symmetrically disposed about said central axis 9.
    Symmetrical placement of the engaging means 11, 12 around said central axis 9 ensures uniform contact between the engaging means 11, 12 and a ceiling, wall or similar construction. This is important for an even and firm attachment of the adjustable valve 1.
    In a preferred embodiment, the present invention provides an adjustable valve 1 according to the first aspect of the invention, wherein one or more clamp openings 14 for providing a measuring tube for measuring the air duct pressure is included in the adjustable valve 1.
    The inclusion of a clamping opening 14 for a measuring tube in the controllable valve 1 is advantageous for a simple measurement of the air duct pressure and consequently flow measurement. Including such a clamping aperture 14 in the controllable valve 1 can be called inventive, since a person skilled in the art would opt for manually gripping a measuring tube or clamping the measuring tube with an external aid, with both options require additional efforts.
    Preferably, said clamping opening 14 for a measuring tube is placed on or within the inner circumference of the housing 2. This is advantageous with regard to easy accessibility of the clamping opening 14 for a measuring tube for air flow measurement. With a mounted adjustable valve 1, the housing 2 is after all statically located in a wall, ceiling or similar construction, while valve 5 and cover element 7 can be adjusted by means of axial translation if desired. In FIG. 4a and FIG. 4b clearly shows a possible embodiment of a housing 2, wherein a clamping opening 14 is located on a supporting rib 21 of the housing 2. In FIG. 5a and FIG. 5b shows a possible embodiment of a housing 2 in which two clamping openings 14 are placed on a said rib 21. Placing a plurality of clamping openings 14 at a different distance from the center of the housing 2 offers the advantage that the air pressure and consequently the air flow can be measured at different positions in the controllable valve 1 by means of a measuring tube. Thus, an image can be formed of the flow profile of air through the adjustable valve 1 and an air duct connected thereto.
    A second aspect of the present invention relates to a method for manufacturing an adjustable valve 1 for an air duct for forced or unforced ventilation of a home and the like, the adjustable valve 1 comprising a housing 2, an adjustable valve 5 and a cover element 7, the method comprising the steps of: - providing a housing 2; - providing a valve 5; - providing a cover element 7; - coaxially placing housing 2, valve 5 and cover element 7, wherein the valve 5 is placed between housing 2 and cover element 7; wherein in one step the housing 2 is provided with one or more spacer members 8.
    The provision of spacer members 8 provides a simple and efficient adjustment of the cover element 7. By physically bringing the cover element 7 into contact with the spacer members 8, a constant distance between cover element 7 and housing 2 is obtained simply and independently of the position of the valve 5. In a preferred embodiment, the spacer members 8 are provided such that they are oriented substantially parallel to the coaxial placement of housing 2, valve 5 and cover element 7. Such an orientation leaves the construction of spacer members 8 with a minimum of material costs.
    In a preferred embodiment, the present invention provides a method according to the second aspect of the invention, wherein providing said housing 2 and providing said valve 5 comprises injection molding a plastic into molds formed for this purpose, and providing said cover element 7 comprises the stamping of a metal.
    For the advantages of the implementation of said housing 2 and valve 5 in plastic and of said cover element 7 in metal, reference is made to the above description of the first aspect of the present invention.
    In one embodiment, the spacer members 8 are only provided on the housing 2 after the housing 2 has been obtained via injection molding of a plastic in a mold formed for this purpose. In another embodiment, a mold is designed for the production of a housing 2 including spacers 8.
    In a preferred embodiment, the present invention provides a method according to the second aspect of the invention, wherein in the step of providing a housing 2 said housing 2 is provided on its inside with one or more clamping openings 14 for including a measuring tube for the measurement of the air duct pressure.
    For the advantages of providing said clamp openings 14, reference is made to the above description of the first aspect of the present invention.
    In one embodiment, said clamping openings 14 are only provided on the housing 2 after the housing 2 has been manufactured, wherein the housing 2 is preferably manufactured via injection molding of a plastic in a mold formed for this purpose.
    In a preferred embodiment, the present invention provides a method according to the second aspect of the invention, wherein the housing 2 equipped with said clamping openings 14 is obtained by injection molding a plastic in a mold formed for this purpose.
    In this way a housing 2 can be obtained quickly which is equipped with one or more of said clamping openings 14, each of which is suitable for including a said measuring tube. Moreover, the whole of housing 2 and said clamping openings 14 form a solid and continuous whole.
    A third aspect of the present invention relates to a use of a method according to the second aspect of the invention for manufacturing an adjustable valve 1 according to the first aspect of the invention.
