Description
- This patent application claims priority from
Italian patent application no. 102021000032471 filed on December 23, 2021 - The present invention concerns a recessed vent for supplying or extracting air into/from a room.
- Vents of the above-mentioned type are known, which comprise a frontally open box-shaped body or plenum and a front grille. The plenum is provided with one or more openings for connection to a duct of a conditioning and/or controlled mechanical ventilation plant and is designed to be recessed in a compartment provided in a wall, for example a plasterboard wall. The grille is generally mounted in contact with the wall, so as to frontally close the body and adhere to the wall around the compartment. In this way, any irregularities in the edge of the compartment are concealed from view.
- Vents are also known in which the grille is mounted flush with the wall in an opening of the wall having predefined dimensions.
- The known vents are suitable for one or the other application.
- This is a drawback not only for the manufacturer, who has to produce different components for the two versions, with higher production and storage costs, but also for the installers, who have to obtain the two different versions.
- The object of the present invention is the production of a universal vent, that solves the above-mentioned problem.
- The above-mentioned object is achieved by a recessed vent for supplying or extracting air into/from a room comprising a frontally open box-shaped body and configured to be housed in a compartment bounded by at least one wall, a front grille fixable to a frame, which is provided with a seat for the grille and a perimeter abutment surface, the frame being configured to be mounted on the body in a first and in a second arrangement, in which the abutment surface faces the body and, respectively, faces away from the body, and comprising adjustment means for varying the distance between the frame and the body, the grille being fixable to the frame in the first and in the second arrangement thereof so as to lie outside the wall or flush with the wall, respectively.
- Thanks to the present invention, the vent is suitable for applications with external grille and applications flush with the wall, thus achieving economies of scale. Furthermore, an installer can purchase one single type of vent for use in both types of application.
- Preferably, the adjustment means comprise a screw system.
- According to a preferred embodiment, the screw system comprises a plurality of screws axially constrainable to the frame and engaging respective threaded holes of the body.
- In this way it is possible to adjust the distance between the body and the frame accurately and in both directions, so that the frame is perfectly matched with an outer or inner surface of the wall.
- Preferably, the screws are axially constrained to the frame by means of releasable locking elements. This allows inversion of the frame for the two possible installation configurations. According to a preferred embodiment, the frame comprises a plurality of through holes for the screws, and the locking elements are configured to fit on the frame in the vicinity of the holes so as to cooperate with respective heads of the screws.
- Preferably, the holes are obtained in internal projections of the frame and define a seat for the head of the respective screw; the locking elements are U-shaped and configured to fit on the respective projection and axially lock the head of the screw, allowing implementation thereof.
- In this way, the assembly is particularly simple.
- According to an embodiment of the invention, the grille is locked in the frame seat by magnetic means. In this way, no discontinuities or fixing elements can be seen.
- Optionally, the mount comprises first supports for housing the grille flush with a flat face of the frame opposite the abutment surface and second supports for housing the grille flush with the frame in the second configuration of the frame. In this way, the grille is always perfectly flush with the frame.
- Preferably, the body comprises guides for housing fixing brackets, said guides being configured to house the brackets in a first position for the front fixing of the body and a second position for the rear fixing of the body. In this way maximum versatility of application is obtained.
- According to a preferred characteristic of the invention, the body comprises a back wall and four side walls facing each other two by two; the back wall and at least two adjacent side walls are provided with removable portions to define an opening for the connection of a duct. Therefore the vent is suitable for connection to a duct extending vertically or horizontally, on both sides.
- For a better understanding of the invention, a preferred embodiment is illustrated below, by way of non-limiting example and with reference to the attached drawings, in which:
-
figure 1 is a perspective view of a recessed vent according to the present invention, in a first configuration thereof; -
figure 2 is a perspective view of the vent in a second configuration thereof; -
figure 3 is an exploded perspective view of the vent in the first configuration thereof; -
figure 4 is an exploded perspective view of the vent in the second configuration thereof; -
figures 5, 6 and 7 illustrate a detail of the vent during successive assembly stages; -
figures 8 and 9 illustrate the vent in a side elevation, in the first and in the second configuration respectively, installed inside a compartment of a wall. - With reference to
figures 1 to 4 , thenumber 1 indicates overall a recessed vent for supplying or extracting air into/from a room produced according to the present invention. - The
vent 1 comprises a box-shaped body orplenum 2, having a substantially parallelepipedal frontally open shape and comprising aback wall 3, fourside walls 4 facing each other two by two and afrontal perimeter flange 5 extending outwards from a frontal edge of theside walls 4. - The
body 2 is designed to be recessed in a compartment obtained in a wall, as can be seen infigures 7 and8 , and will be described in further detail below. - The
vent 1 further comprises arectangular frame 6 arranged parallel to theback wall 3 and designed to be connected to thebody 2 inside theflange 5. - Lastly, the
vent 1 comprises agrille 7 designed to be removably fixed to theframe 6 so as to frontally bound thebody 2, allowing passage of the air. - As can be clearly seen from the comparison between
figures 3 and4 , theframe 6 can be fixed to thebody 2 in two different arrangements, upturned with respect to each other, and its distance from thebody 2 can be adjusted as described below. - In particular, in the non-limiting example illustrated, the frame comprises a
perimeter flange 10 provided with a flat face 8 (figures 3 ,9 ) and an opposite abutment surface 9 (figure 4 ), and can be fixed to thebody 2 with theflat face 8 facing the front and the abutment surface facing the body 2 (figures 1 ,3 ,8 ) or with theflat face 8 facing thebody 2 and theabutment surface 9 facing the front (figures 2 ,4 ,9 ). - The
frame 6 further comprises amount 11 extending from an internal edge of theperimeter flange 10 in the area of theabutment surface 9; themount 11 defines internally aseat 21 designed to house thegrille 7 and has along an inner surface thereof a projection in the shape of aGreek key pattern 12 defining two sets ofsupports supports 12a are arranged so as to define an abutment surface for thegrille 7 such that thegrille 7, when introduced into themount 11 in the area of theflat face 8 of theframe 6, is flush with said face (figure 3 ). Thesupports 12b are arranged so as to define an abutment surface for thegrille 7 such that thegrille 7, when introduced into themount 11 in the area of theabutment surface 9 of theframe 6, is flush with one end of themount 11 opposite the perimeter flange 10 (figure 4 ). The axial extension of themount 11 beyond theabutment surface 9 of theframe 6 is expediently equal to the typical thickness of a double layer plasterboard wall (fig. 9 ). - The
body 2 carries integrally fourcylindrical bushes 13, having axes perpendicular to theback wall 3 and arranged in the vicinity of the internal corners of thebody 2. Thebushes 13 are provided with respective threadedaxial holes 14 forrespective screws 15 for connecting theframe 6. Thescrews 15 expediently have acountersunk socket head 16 and a threadedstem 17. - The
frame 6 has in turn fourinternal projections 18 in the shape of a square plate, arranged in the vicinity of the internal corners of the frame and in a position facing thebushes 13 of thebody 1. - More in particular, the
projections 18, one of which can be clearly seen infigures 5 and 6 , extend on opposite sides of theframe 6 towards the inside, in the vicinity of the internal corners of theframe 6. Theprojections 18 are each provided with athrough hole 19 for thestem 17 of therespective screw 15 with a flaredportion 20 having the function of a seat for thehead 16 of the screw 15 (figure 5 ). - Lastly, the
vent 1 comprises fourlocking elements 24, designed to slidingly couple with therespective projections 18. Each locking element (figures 5-7 ) is substantially U-shaped and comprises a pair oflongitudinal portions 25 parallel to each other and atransverse portion 26 integrally connecting to each other respective ends of thelongitudinal portions 25. The latter have a substantially C-shaped cross section with concavities facing each other so as to define respectiveinternal seats 27 slidingly couplable with respective lateral edges of the projections 18 (figure 6 ). - The longitudinal portions are spaced from each other by a distance greater than the diameter of the
stem 17 but less than the maximum diameter of thehead 16 of thescrews 15, so as to axially lock thehead 16 in theseat 20 while allowing access to the hexagon socket of thehead 16 by means of a key (figure 7 ) . - The
body 2 of thevent 1 is expediently provided with circularremovable portions 30 made on theback wall 3 and on a pair ofside walls 4 adjacent and orthogonal to each other. Infigures 1, 2 ,3 and4 one of the removable portions is removed, thus leaving free acircular opening 31. Infigures 1 and 2 acoupling 32 is illustrated designed to be connected, for example by bayonet coupling, to thecircular opening 31; a duct (not illustrated) of a conditioning and/or controlled mechanical ventilation plant can be connected to thiscoupling 32 in a known way. Thanks to the presence of threeremovable portions 30 arranged as described, thebody 2 can be connected to a lateral, vertical or rear duct by removing the correspondingremovable portion 30. - Lastly, the
body 2 has a plurality ofguides 33 to slidingly house fixingbrackets 34. - There are expediently four
guides 33, arranged two by two onopposite side walls 4 and extending at the sides of therespective side walls 4 in a direction perpendicular to theback wall 3. Thebrackets 34 are expediently L-shaped and can be fitted in the respective guides or in the area of the back wall (figures 1 ,3 ) or in the area of thefront flange 5 of the body 2 (figures 2 ,4 ), so as to allow fixing on aback wall 40 of the compartment in which the vent is recessed (rear fixing -figure 8 ), or on afront wall 41 that frontally bounds said compartment (front fixing -figure 9 ) and is provided with anopening 42 for housing themount 11 of theframe 6. - It should be noted that the two fixing methods, illustrated by way of example with reference to the first configuration of the vent (
figure 1 ) and, respectively, the second configuration of the vent (figure 2 ), do not depend on said configuration but only on the conditions of constraint and possibilities of access existing in the specific situation; therefore it is also possible to use a front fixing in the first configuration and a rear fixing in the second configuration. - Assembly of the
vent 1 is described below, first with reference to the first assembly configuration (with external grille) illustrated infigures 1 ,3 and8 , in the case of rear fixing. - In this configuration, first the
body 2 is fixed to thewall 40 by means of thebrackets 34. Subsequently, theframe 6 is fixed to thebody 2. - At this point the
front wall 41 is cut to size and applied, if the wall is made of plasterboard, providing theopening 42, the dimensions of which approximate by excess the transverse dimensions of themount 11 of theframe 6 and the edges of which frontally match theflange 5 of themain body 2. - To fix the
frame 6 to thebody 2, thescrews 15 are inserted in theholes 19 of theprojections 18 of the frame 6 (figure 5 ), so that therelative head 16 is housed in the tapered seat 20 (figure 6 ). Thescrews 15 are then axially locked with respect to theframe 6, inserting the lockingelements 24 on the projections 18 (figures 6 and 7 ). - The
frame 6 can now be fixed to thebody 2 by tightening thescrews 15 in theholes 14 of thebody 2. By tightening thescrews 15, theframe 6 moves progressively towards thebody 2 until theabutment surface 9 of theflange 10 abuts against the front wall 41 (figure 8 ). Any dimensional imperfections of theopening 42 of thefront wall 41 are therefore concealed from view. - The last assembly stage consists in application of the
grille 7. The fixing of thegrille 7 is expediently of magnetic type. For this purpose,magnets 44 can be fixed to the grille 7 (figures 3 and4 ) designed to cooperate with theheads 16 of thescrews 15, if ferromagnetic, or with corresponding ferromagnetic elements embedded in the frame 6 (not illustrated). Thegrille 7 can be provided with at least one notch along a side thereof for the insertion of a tool, for example a screwdriver, to remove thegrille 7 from theframe 6, if necessary. - In the second configuration, and in the case of front fixing illustrated in
figure 9 , theframe 6 must be pre-assembled on thebody 2 before fixing the latter to thefront wall 41; in this case theframe 6 is mounted in an upturned position, namely with theflat face 8 facing thebody 2. - For assembly, the
screws 15 are inserted in theholes 19 of theprojections 18 and tightened in thebushes 13 of thebody 2, until theframe 6 is brought near to thebody 2. The lockingelements 24 can be inserted also after tightening of thescrews 15. - The
frame 6 is then mounted on thebody 2 so that theflat face 8 abuts against theflange 5 of thebody 2 providing an air seal. - The
body 2 is then fixed to thefront wall 41 by means of thebrackets 34, so that themount 11 of theframe 6 is arranged inside theopening 42. - Lastly, the
grille 7 is mounted in theframe 6, the grille being flush with the wall as described above. - If the vent in its second configuration is mounted with rear fixing, it is possible to fix first the
body 2 to therear wall 40 and then fix theframe 6 to thebody 2. Thefront wall 41 provided with theopening 42 is then applied. - From an examination of the characteristics of the
vent 1 produced according to the present invention, the advantages it offers are evident. - The possibility of assembling the
frame 6 in two configurations, one upturned relative to the other, in combination with the adjustable connection between thebody 2 and theframe 6, allows thevent 1 to be assembled in a configuration with grille overlapping the wall and in a second configuration flush with the wall. - This results in economies of scale in terms of both production and utilisation, and greater ease of application.
- Furthermore, the possibility of fixing the body at the rear or at the front increases the versatility of use and adaptability to different specific conditions.
- Lastly, it is clear that modifications and variations can be made to the
vent 1 described that do not depart from the protective scope defined by the claims. - In particular, the adjustment system for adjusting the relative distance between
body 2 andframe 6 can be modified.
