[0001] LINEAR PLASTERED DIFFUSER AND METHOD OF CONNECTING LINEAR

[0002] PLASTERED DIFFUSERS

[0003] Technical Field

[0004] The invention relates to ventilation linear slot diffusers, and, more specifically, to the plastered linear diffusers and methods of connecting them.

[0005] Technical Level

[0006] A plastered slot diffuser is part of a forced ventilation system for installation in the ceiling. Unlike surface-mounted diffusers, the plastered / integrated diffuser is completely hidden under the gypsum ceiling. When installing linear-type ventilation diffusers that are plastered and hidden under the gypsum boards, it is essential to maintain aesthetic properties and linear and precise connection of individual segments. If the process is long and complicated, such installation increases labor costs and reduces economic value.

[0007] To install a ventilation system with high airflow, long linear diffusers are often used. Frameless linear diffusers available on the market are made of aluminum profiles or gypsum. They are connected simply by abutting them together and there may be connection inaccuracies visible to the naked eye at the connection points. In the case of gypsum diffusers, such inaccuracies have to be sanded and smoothed in order to eliminate them. In case of metal diffusers, irregularities cannot be corrected and remain visible. In addition, the longer the diffuser, the greater the chance of making a mistake during installation and making the entire long line smooth.

[0008] For current diffusers available on the market, the diffusers have to be connected through junction boxes, thus creating a connection that is actually not in the right place where it is needed most (i.e. in the visible plane).

[0009] The closest prior art is disclosed in U.S. Patent Application No. US71 1 ,715, publication US2016334128. The disclosed air diffuser is formed to the full length required for the application at once. The length of such a diffuser can only be changed during the manufacture of the diffuser. When connecting several such diffusers, the gap between them creates conditions for inaccurate connections and cracking of the putty at the connection point. The invention does not have the above disadvantages and comprises additional advantages.

[0010] Summary of the invention

[0011] The invention according to one aspect in is a linear plastered diffuser comprising a faceplate, a junction box and preferably a flow regulator for the airflow through a slot in the diffuser faceplate. The diffuser face plate comprises at least two segments and a longitudinal slot between the segments arranged parallel to each other, which forms a pair of segments. Each diffuser segment comprises two connecting ends.

[0012] According to the second aspect, a method of connecting linear plastered diffusers is disclosed. The method comprises positioning the end of a first segment with a first connecting surface adjacent to the end of a second segment with a second connecting surface of the pair and positioning the end of the first segment with a second connecting surface of the pair adjacent to the end of the second segment with a first connecting surface of the pair. At least one additional segment is attached to each of the segments of the pair in such a way that the first connecting surface of each of the segments attached one after the other along the length contacts the second connecting surface of the further segment by introducing the projection into the recess, or the second connecting surface contacts the first connecting surface of the further segment by introducing the projection into the recess.

[0013] Short Description of Drawings

[0014] The features of the invention, which is new and non-obvious, are provided in the Claims. However, the invention may be best understood from the following detailed description of the invention, in which, without limiting the scope of the invention, exemplary embodiments of the invention are provided in conjunction with the accompanying drawings, where:

[0015] Fig. 1 shows the connecting ends of a linear plastered diffuser segment.

[0016] Fig. 2 shows the connected segments of a linear plastered diffuser into a continuous linear plastered diffuser.

[0017] The preferred embodiments of the invention are described below with reference to the drawings. Each item or equivalent item in each figure has the same numbering. Detailed description of the invention

[0018] According to one aspect, the invention discloses a linear plastered diffuser (1 ) comprising a face plate (FP) of at least two segments (1.1 1 , 1.12) and a junction box (2). The diffuser (1 ) according to the invention may also include a flow regulator for the air flow through the slot in the diffuser face plate.

[0019] The plastered diffuser segment (1.1 1 ), hereinafter referred to as segment (1.1 1 ), is intended to form a face-plate of a linear plastered diffuser (1 ), which would include at least two such segments (1.1 1 , 1.12) and a longitudinal slot (1.2) between the segments (1.1 1 , 1.12) arranged parallel to each other, which form a pair of segments. Depending on the need, the diffuser (1 ) can be formed of an unlimited number of pairs of segments (1.1 1 , 1.12). The junction box (2) of the diffuser (1 ) is attached to at least two diffuser segments (1.1 1 , 1 .12). Depending on the length of the formed diffuser (1 ), more than one junction box (2) is installed.

[0020] All mentioned diffuser segments (1.1 1 , 1.12, 1.13, 1.14) comprise the same features.

[0021] Further on, the features of one segment (1.1 1 ) will be disclosed. The segment (1.1 1 ) comprises a face surface (1.3) intended for plastering, an air gap surface (1.4), a fastening surface (1.5) for the diffuser junction box (2), a first surface (1.6) for fastening the segment to the fastening profile (3), further referred to as the first fastening surface (1 .6), and a second surface (1 .7) for fastening the segment to the fastening profile, further referred to as the second fastening surface (1.7), a first connecting surface (1 .8) and a second connecting surface (1 .9).

[0022] The face surface (1.3) comprises at least one, but preferably more than one, first fastening zone (1.31 ) for fastening the segment (1.1 1 ) to the fastening profile (3). Said first fastening zone (1.31 ) comprises a recess or a partial hole, or a hole extending through the entire thickness of the segment (1.1 1 ), which is intended for positioning a fastening element, such as a screw. The fastening profile (3) is a structural element intended for attachment to the construction elements, such as walls and ceilings, where additional structural and finishing elements, such as gypsum board panels, diffusers, etc., are attached to said fastening profiles (3). The face surface (1 .3) also comprises at least one, but preferably more than one, second fastening zone (1 .32) for fastening the segment (1 .1 1 ) to the junction box (2) of the diffuser. Said second fastening zone (1 .32) comprises a recess or a partial hole, or a hole extending through the entire thickness of the segment (1.1 1 ), which is intended for positioning a fastening element, such as a screw.

[0023] The air gap surface (1 .4) extends along the entire length of the segment (1.1 1 ) and through the entire thickness of the segment (1.11 ). The air gap surface (1.4) is preferably smooth, not obstructing the flow of air.

[0024] The fastening surface (1 .5) of the diffuser junction box (2) is intended for positioning the diffuser on a part of the segment (1 .1 1 ) so that the longitudinal slot (1 .2) between the parallel segments (1.1 1 , 1.12) coincides with the slot for the air flow exit from the diffuser junction box (2). The air flow regulator is preferably positioned above said longitudinal slot (1.2) and which can be adjusted through said longitudinal slot (1 -2).

[0025] The first fastening surface (1 .6) extends over the entire length of the segment (1.1 1 ) and at least part of the thickness of the segment (1 .1 1 ) and is intended to contact part of the side surface (3.1 ) of the fastening profile (3).

[0026] The second fastening surface (1 .7) extends over the entire length of the segment (1.1 1 ) and at least part of the width of the segment (1.1 1 ) and is intended to contact part of the front surface (3.2) of the fastening profile (3).

[0027] The first fastening surface (1.6) is adjacent to the second fastening surface (1.7), where the angle a between the plane (Pte) of the first fastening surface (1.6) and the plane (P1.7) of the second fastening surface (1.7) corresponds to the angle [3 between the plane (P3.1) of the side surface (3.1 ) of the fastening profile (3) and the plane (P3.2) of the front surface (3.2) of the fastening profile (3).

[0028] The first connecting surface (1.8) comprises a recess (1.81 ) for receiving a projection (1 .91 ) of the second connecting surface (1 .9). A first connecting surface

[0029] (1.8) is formed at one end of the segment (1.1 1 ). The recess (1.81 ) of the first connecting surface (1 .8) comprises a socket (1 .81 1 ) that is wider than the support portion (1 .812) of the recess (1 .81 ) of the first connecting surface (1 .8) for supporting the support portion (1 .912) of the projection (1 .91 ) of the second connecting surface (1 -9).

[0030] The second connecting surface (1 .9) comprises a projection (1 .91 ) for inserting into recess (1.81 ) of the first connecting surface (1.8). The second connecting surface

[0031] (1 .9) is formed at the other end of the segment (1.11 ), which is opposite to the end where the first connecting surface (1.8) is formed. The projection (1.91 ) of the second connecting surface (1 .9) comprises a neck portion (1 .91 1 ) that is narrower than the supporting portion (1 .912) of the projection (1 .91 ) of the second connecting surface (1 .9), which is intended to abut against the supporting portion (1 .812) of the recess (1 .81 ) of the first connecting surface (1 .8).

[0032] The width of the socket (1 .81 1 ) of the recess (1 .81 ) of the first connecting surface

[0033] (1 .8) corresponds to the width of the neck portion (1 .91 1 ) of the projection (1 .91 ) of the second connecting surface (1 .9), and the width of the support portion (1 .812) of the recess (1 .81 ) of the first connecting surface (1 .8) corresponds to the width of the support portion (1.912) of the projection (1.91 ) of the second connecting surface

[0034] (1 .9). Such a width ratio allows the first connecting surface (1 .8) to be connected to the second connecting surface (1 .9) by limiting the longitudinal movement of the end-connected segments (1.11 ) relative to each other but leaving them free to move up and down relative to each other, parallel to the direction of air flow through the diffuser slot (1 .2).

[0035] The method of connecting plastered diffusers comprises positioning at least two segments (1.11 , 1.12) in one plane, parallel to each other and with the air gap surfaces (1.4) of both segments (1.1 1 , 1.12) facing each other. Both segments (1.1 1 , 1 .12) of the pair are positioned relative to each other by forming a gap (1 .2) between them, directing the face surfaces (1.3) of both segments in the same direction. At the same time, the end of the first segment (1.1 1 ) of the pair of segments (1.1 1 , 1.12) with the first connecting surface (1.8) is positioned adjacent to the end of the second segment (1.12) of the pair of segments (1.1 1 , 1.12) with the second connecting surface (1 .9), and the end of the first segment (1 .1 1 ) of the pair (1 .1 1 , 1.12) with the second connecting surface (1 .9) is positioned adjacent to the end of the second segment (1.12) of the pair (1.1 1 , 1.12) with the first connecting surface (1.8). Additionally, an extra segment (1.13, 1.14) may be attached to each of the segments of the pair of segments (1.1 1 , 1.12) so that the first connecting surface (1 .8) of each of the segments (1 .1 1 , 1 .12, 1 .13, 1.14) attached one after the other along the length comes into contact with the second connecting surface (1 .9) of the further segment by introducing the projection (1 .91 ) into the recess (1 .81 ), or the second connecting surface (1 .9) comes into contact with the first connecting surface (1.8) of the further segment by introducing the projection (1.91 ) into the recess (1 .81 ). The diffuser (1 ) of two or more segments (1 .11 , 1 .12) is attached to two parallel and coplanar fastening profiles (3), each segment (1.1 1 , 1.12, 1.13, 1.14) being positioned to the corresponding fastening profile (3) so that the portion of the first fastening surface (1 .6) of each segment rests against the portion of the side surface (3.1 ) of the fastening profile (3) and the portion of the second fastening surface (1 .7) of each segment rests against the portion of the front surface (3.2) of the fastening profile (3) to which the segments (1.1 1 , 1.12, 1.13, 1.14) are screwed. Thus, the movement of the segments (1.11 , 1.12, 1.13, 1.14) is limited in the transverse direction and in the upward direction relative to the fastening profiles (3), and the movement in the longitudinal direction and in the downward direction relative to the fastening profiles (3) is limited by fastening elements attaching the segments (1.1 1 , 1.12, 1.13, 1.14) to the fastening profiles (3). This type of connection is extremely precise and strong.

[0036] By placing the linear diffuser segment (1.1 1 ) against the ceiling fastening profile (3), it can be attached by one person, it is enough to press it with one hand because the segment (1.1 1 ) cannot deviate to the side, and with the other hand to screw the diffuser segment (1 .1 1 ) directly to the same fastening profile (3) of plaster ceiling.

[0037] The diffusers (1 ) are locked and brought together in the plane where the finishing will be done. This creates consistent quality, and the gap is even and precise, allowing the diffuser to be finished immediately without having to correct any irregularities, thus saving money on finishing work and reducing the overall costs of construction.
