Definitions

  • This invention relates to a ventilation grille or device which is intended to be installed in a window, door or similar construction and which comprises a rotary ventilation grille proper.
  • Such a rotary ventilation grille proper is known per se and for example described in NL-A-8 105 360.
  • Such a rotary ventilation grille consists mainly of a drum fitted with diametrically opposite longitudinal grooves and in which the vertical placement in superposition , respectively the horizontal placement in consecution of these grooves has the effect that a junction is made or not between the two sides of the ventilation grille.
  • the present invention relates more particularly to soundproofing of these rotary ventilation grilles which ensures that the noise, originating from the outside, is as much as possible muffled and that it does not penetrate or that it does not introduce itself or weakly in the space equipped with such a ventilation grille.
  • the ventilation device comprises a sound-absorbing housing which is provided on one side of the grid, which comprises profiles which cooperate with the constituent profiles of the grid and which is formed by an upper part and a lower part which does not are connected to each other only by their ends, the assembly formed by the profiles of the upper part of the housing and the upper constituent profiles of the grid maintaining at least one upper layer of sound-absorbing material at a distance of at least at least one lower layer of soundproofing material independent of the upper layer and carried by the assembly formed by the profiles of the lower part of the housing and the lower profiles of the rotary grid, a channel being formed between these layers of soundproofing material which forms a connection between the rotary ventilation grid and the atmosphere.
  • a ventilation device comprising a ventilation grille proper and a sound-absorbing housing is already described.
  • the ventilation grille is not, however, a rotating grille but a sliding grille.
  • the housing which is inside with respect to the grid has an upper part and a lower part made of a material which is poor conductor of heat. Face towards the grid sliding of a wall located opposite this grid is covered with a layer of soundproofing material.
  • the sliding part of the grid is covered on the outside with a layer of an elastic material such as synthetic foam. No channel forming a connection between the sliding grid and the atmosphere is formed between independent layers of soundproofing material.
  • Figure 1 shows a window, door or other construction 1 which is designed to receive a ventilation device 2 according to the invention so that the complete ventilation device is located inside the space in which it is installed.
  • the ventilation device mainly consists of two parts, that is to say the rotary ventilation grid 3 per se and the soundproofing part or the soundproofing box 4.
  • the rotary ventilation grid 3 consists in this embodiment mainly in two sections, respectively 5 and 6 which are fixed reciprocally in a known manner not shown by end plates and where these sections 5 and 6 each have two spaces, respectively 7, 8 and 9, 10, for fixing a brush 11 where two shells, respectively 12 and 13, cooperate which are also mutually connected at their ends and which can be turned relative to the sections 5 and 6 in order to realize that the slots 14 and 15 formed between the shells 12 and 13 establish a connection, either in their entirety or partially, between one and the other side of the ventilation grille, or to hermetically seal these sides between them.
  • the grid is equipped on the one hand with a projection 17 on the profile 5 and on the other hand with a hook-shaped protuberance 18 below the profile 6.
  • the sound absorbing housing 4 according to the invention is designed in such a way that it cannot only be widened or raised, but that it can be, seen in section, installed in determined locations relative to the window with which it must cooperate, i.e. it can be placed more or less inwards or outwards in the construction where it is installed, always taking into account the installation of an appropriate thermal interruption .
  • the soundproofing box is mainly formed by an upper part 19 and a lower part 20 which are connected, not shown, but suitably by their ends, as is the case for the rotary ventilation grid. 3, by end plates.
  • the upper part 19 is formed by a first external profile 21, a corner profile 22, an intermediate profile 23 and a terminal profile 24.
  • the angle profile 21 consists in this case of a downwardly hanging part 25 which, so to speak, prevents water from entering the housing, where the profile has two protuberances, respectively 26 and 27, for the support of a layer of soundproofing material 28, on the one hand, and a hook-shaped end 29 and a distance support 30, on the other hand, which form, so to speak, the coupling elements.
  • the corner profile 22 has a free end 31 which can cooperate with the hook-shaped end 29 of the angle profile 21 and a tongue 32 placed around it, the free end of which rests against the support 30 of the angle profile 21, placed on this end 29
  • These parts 31, 32 form coupling elements which can cooperate with the coupling elements 29, 30.
  • the second upright of the corner profile 22 has a hook-shaped element 29 at its end and a protuberance 30 as it was the case for the profile 21. Between them the profile 22 has wings, respectively 33 and 34, the free ends of which have parts, respectively 35 and 36, which are parallel with the external surface of the profile 22 and which serve as a shoulder for the layer of soundproofing material 28.
  • a layer of thermal insulation material 37 is provided between the wings 33 and 34 which, in known manner, can be obtained by pouring such a material into the profile 22 and then cutting out a part 38 of it. profiled in order to obtain a thermal interruption.
  • the profile 23 is formed at one end by the above elements 29 and 30 and at the other end by the above elements 31 and 32. Likewise, the wings 33, 34 and the parts 35, 36 are provided in such a way that material 37 can be poured into it and forms a possible interruption 38.
  • section 24 consists in an identical manner to the previous of the parts 30 to 36 while a curved part 39 is provided at one of the ends with which the protuberance 17 of the rotary ventilation grid 3 can cooperate.
  • the upper part 19 is completed by a profile 40 whose arms 41 and 42 serve as shoulders for a layer of soundproofing material 28 and where this profile also fits into the profile 5 of the grid 3.
  • the lower part 20 of the housing 4 is mainly produced by a section 24 mentioned above and an almost double section 23 which is indicated in this case by 43.
  • this profile 43 does not only present the elements of the profile 23, but also a pair of intermediate wings 33, 34 with protrusions 35, 36.
  • an angle profile 44 is provided which presents the elements 29 and 30 mentioned above and which is curved towards the inside of the housing 4 so as to preferably have a protuberance 45 placed at 45 degrees which in this case has four spaces 46 above which are each limited by a shaped edge 45 mushroom and where in these adjustment spaces 46, respectively between two mushroom-shaped edges 47, an inverted mushroom-shaped edge 48 of an adjustment profile 49 can be installed which has a curved portion 50 in order to position the layer sound absorbing absorbent 51, with the protrusions 35, 36 of the sections 24 and 43, on the one hand, and the section 6 of the rotary ventilation grid 3, on the other.
  • a rotary sound-absorbing ventilation device that is to say a rotary ventilation grid 3 which is produced with a sound-absorbing housing 4 and where this sound-absorbing housing, in a simple manner, instead of a window, of a door or the like 1, is fitted with a thermal break 37.
  • the rotary ventilation grille 3 may be, as indicated schematically by a dotted line in FIG. 1, hooked in a simple manner by means of the hook-shaped end 18 of the profile 6 behind a hook-shaped end 39 of a profile 24 so as to then be pivoted upwards and to be fixed by one or more screws not shown to the construction of the housing 4.
  • This embodiment also makes it possible to be appropriately widened by the insertion of one or more elements 19, both at the top and at the bottom, while the adjustment of the air flow 52 is possible by the displacement of the profile 49 by relative to the profile 44 as shown by a dashed line in FIG. 1.
  • FIG. 2 represents an embodiment where the rotary ventilation grid is formed in a perfectly identical manner as described above and where the sections 21, 24, 43, 44, 49, 40 and 44 are used for the soundproofing box, where the only difference between the previous one resides in that the angle profile 21 cooperates in this case with a profile 53 which is formed identically to that described above but which is equipped with an inclined part.
  • thermal break 37 is located practically in the center of the housing 4, the whole so that this housing is placed for half outside and half inside construction 1.
  • a sound-absorbing ventilation device is obtained in this way that it can be produced in different heights and widths, in which the same series of constituent profiles is practically always applied and in which in several places, according to the desired construction, a cryogenic bridge can be provided, on the one hand, and where the air passage 52 can be reduced or increased in order to influence the ventilation flow, on the one hand, and the passage of noise, d 'somewhere else.
