Definitions

  • the present invention relates to a baffle system comprising a plurality of profiles provided for mounting to a building construction and at least one baffle element provided for mounting to the at least one profile through attachment means provided thereto, as disclosed in the preamble of the first claim.
  • each baffle element has the shape of a plate the opposite faces of which are covered with a sound absorbing material.
  • the baffle elements extend under an angle of between 15 and 75° with respect to a vertical plane.
  • the top side of each baffle element comprises a hook for attaching the baffle element to a T-profile, which is directly mounted to the building construction, whereas the bottom side is connected to a first end of a tow or cord. The second end of the tow is attached to the T-profile of a subsequent baffle element.
  • DE-A1-4229712 is most probably designed for use in an industrial environment as it is unattractive from an aesthetic point of view, because of the visible presence of a plurality of hooks and tows or cords. Besides this the system of DE-A1-4229712 presents the disadvantage that the accessibility of the plenum between and above the baffles is difficult and time consuming.
  • the baffle system of this invention is further characterised in that the attachment means comprise first and second attachment means provided on respectively the first and second side of the baffle element and corresponding third and fourth attachment means provided on a side of the corresponding first and second profiles facing the first and second side of the baffle elements, and in that the first and third, respectively the second and fourth attachment means point towards each other sideways of the baffle element and the profiles.
  • baffle element The sideways connection of the baffle element to the facing profile facilitates mounting of the baffle element to the suspension grid and provides the possibility of rendering the connection almost invisible from a position below the baffle system.
  • Connecting the baffle elements to a building construction through the intervention of a suspension grid results in a system in which the baffle elements may be suspended at a lowered position with respect to the building construction.

  • first, second, third and fourth attachment means are provided to attach the at least one baffle element to both the first and second profile in such a way that the baffle element is hinged with respect to the first and second profile.
  • first and second profile may for example run parallel, although the first and second profile may also slant with respect to each other or point away from each other.
  • the hinged mounting of the baffle elements not only facilitates their mounting.
  • the hinged mounting also allows mounting a baffle element with its faces extending under any desired angle with respect to the perpendicular, independently of the position and shape of the profile to which the baffle is suspended or the shape of the building construction.
  • subsequent baffle elements attached to the first and a second profile may namely extend parallel or perpendicular to each other or slant with respect to each other. In that way any sound which, with parallel extending baffle elements could pass between subsequent elements, can now be absorbed.
  • a preferred embodiment of the baffle system of this invention which further facilitates mounting of the baffle elements to the suspension grid, is characterised in that the first and second attachment means comprise a (i) first recess provided in the first side of the baffle element, (ii) a second recess provided in the second side of the baffle element, (iii) a third and a fourth recess provided in respectively the first and second profile, (iv) at least one first pin provided to be received in both the first and the at least one third recess and (v) at least one second pin provided to be received in both the second and the least one fourth recess.
  • a practical embodiment of the fastening means is characterised in that the at least one third recess in the profile extends throughout the thickness of the profile in a connection direction of the baffle element and the profile.

  • the first pin part is provided for mounting to a first side of the profile
  • the second pin part is provided for mounting to a second side of the profile, the first and second pin part being provided to be connected to each other.
  • first or second pin part After connecting the first and second pin part, either the first or second pin part is received in the first or second recess in the first or second side of the baffle element to hingedly mount the baffle element to the profile.
  • a tension is exerted to the first and second pin part as a consequence of which a sturdy connection between the first and second pin part is obtained.
  • the baffle system of this invention is characterised in that the third and fourth profiles are moveably mounted with respect to respectively the first and second profiles in longitudinal direction of the profiles.
  • a baffle system in which baffle elements extend in longitudinal as well as in transverse direction or any direction in between, is obtained by a system which is characterised by a suspension grid comprising a plurality of profiles extending in longitudinal direction and a plurality of profiles extending in transverse direction of the suspension grid, a transverse profile connecting adjacent longitudinal profiles.
  • These transverse profiles may extend at the level of the first and second profiles, or the level of the third and fourth profiles or both, or at any other level which might be imposed by the circumstances.
  • An additional embodiment of the baffle system of this invention is characterised in that the at least one baffle element is removable mountable to the suspension grid, in view of improving the accessibility of the plenum behind or above the baffle system.
  • a baffle system which is characterised by the presence of a plurality of parallel first profiles which extend parallel to, perpendicular to or slant with respect to a level of the building construction or a combination of two or more of those first profiles, may be used in a wide diversity of applications.
  • Such a baffle system may for example be used as a sun screen having acoustic isolating properties.

Thereby the first and second angle may be different from each other. It is furthermore possible that the third and fourth profiles are displaceable with respect to the first and second profiles in longitudinal direction of the profiles.

  • the profiles 21-25 preferably form part of a suspension grid which is adapted to accommodate lightning, electrical appliances, aeration equipment or any other equipment between the baffle elements 1.
  • the baffle system 10 of the present invention may have a regular shape, which means that the bottom faces 26 of the baffle elements 1, 11 run for example virtually horizontal, parallel to the ceiling, parallel to the floor, slant with respect to the ceiling or with respect to any other wall of a building construction.
  • first and second sides 12, 13 of a baffle element 1, 11 extend in line or not.
  • This may for example be achieved with a baffle element opposite sides of which are connected to opposite profiles at positions which are shifted with respect to each other in longitudinal direction ( figure 5 ).
  • the person skilled in the art thus has the choice to attach a baffle element to a suspension grid such that it depends vertically therefrom. It is however also possible to vary the position of the baffle element in three dimensions as has been described above.
  • the baffle system 10 of this invention may also have an irregular shape and contain substantially horizontal and substantially vertical extending profiles, bent profiles or profiles formed in any other desired shape and extending in any desired direction.
  • the baffle system of this invention may be designed to take an aesthetically attractive shape, without this going at the expense of possible sound absorbing properties provided by it.
  • the baffle element may be made of a sheet with an upper and lower side, which are fixed to each other on at least one position by means of a cord.
  • the present invention also relates to a baffle element as part of the above described baffle system.
