  • the first, second, fifth and sixth attachment means 4, 5, 14, 15 have an elongated shape with a rounded end part, to facilitate insertion of the pin 19, 29.
  • the first, second, fifth and sixth attachment means 4, 5, 14, 15, are cross-shaped with rounded end parts ( figure 7 ).
  • the baffle element 1, 11 to the pin is facilitated as the cross shaped recess has a central hole with a relatively large diameter which facilitates insertion of the pin in the central recess and contributes to the ease of removing the baffle element from the system when necessary.
  • the baffle element may suspend from the pin due to gravitational forces, in that case the top edge of the recess will be suspended to the pin 19, 29.
  • the baffle element may be completely locked in vertical position and displacement of the baffle element in vertical direction is limited to the dimensions of the recess.
  • the presence of the cross shaped recess allows positioning the baffle element 1, 11 in any desired position, i.e. suspending substantially vertical from the suspension grid, in a suspending or upstanding position, or extending substantially horizontal with respect to the suspension grid.
  • the baffle element comprises two recesses on the same side, the horizontal position of the baffle element may be fixed with respect to the suspension grid by suspending both recesses to a suspension pin 19.
  • an end part of the pin may comprise at least one circumferential groove 40 which is provided to receive an edge of the recess 4, 5, 14, 15 provided in the sides of the baffle element 1, 11 or an edged formed by the frame surrounding the baffle element and comprising the recesses ( fig. 7 ). If so desired, a multiplicity of consecutive grooves may be provided along the length of the pin.
  • the dimensions of the recesses 4, 5, 14, 15 will preferably be chosen such that they are hidden by the profiles 21-25.
  • the circumferential groove 40 is substantially V-shaped, both faces of the V extending under an angle of preferably 90° to allow mounting adjacent baffle elements 1, 11 in a herringbone arrangement as is shown in figure 5 .
  • the preferred embodiment in which the baffle element 1, 11 is removably connectible to the suspension grid 21-25 and may be fixed in a specific angle with respect to the suspension grid may be achieved by using a pin made of a first and a second pin part 8, 18, a part of which extends through the recess 6, 7 in the profile 21-25, the first and second pin part 8, 18 being removably connectible to each other.
  • Simple connection of the baffle element 1, 11 to the suspension grid may be achieved by first fastening the first and second pin part to each other, each pin part being mounted to the appropriate side of a profile 21-25, and thereafter suspending the baffle element 1, 11 to the pin 19, 29.
  • baffle system which provides for an easy mounting of the baffle elements, in which the baffle elements 1, 11 may hinge with respect to the suspension grid, and in which baffle elements may be mounted side by side.
  • the pin parts 8, 18 may have the same or a different length.
  • the length of the pin parts are not critical to the invention, but will usually be selected taking account of the envisaged positioning of the baffle element mounted thereon. For example a pin part with a longer length will be required in case the side 12, 13 of the baffle element points away from the profile to which it is fastened and extends under an angle with respect to the profile.
  • each pin part 8, 18 will be chosen such that it is not visible from below, or in other words the length of each pin part will be chosen such that it is hidden by the bottom part of the profile. It is however also possible to use attachment means which allow mounting a baffle element under a specific angle with respect to the corresponding first and second or third and fourth profile.
  • the position of the baffle elements with respect to the suspension grid may be fixed by attaching the first and second attachment means 4, 5 to the first and second profile 21, 22 and the fifth and sixth attachment means 14, 15 to the third and fourth profile 23, 24.
  • This fixed positioning is particularly useful in a situation where a permanent circulation of air might impart a permanent clinging of the baffle elements, or in a situation where it is desirable to fix the position of the baffle elements independently of the shape of the ceiling to achieve optimum sound absorption, if so desired combined with optimum aesthetic effect.
  • the position of the baffle elements may be changed all together if so desired ( figure 4 ). It is also possible to have the first and second profile 21, 22 displaceable with respect to the third and fourth profile 23, 24.
  • the profiles 21-25 used in the baffle system 10 of this invention may be any profiles known to the person skilled in the art. To achieve the highest possible versatility, the profiles 21-25 form part of a suspension grid, which is suspended to the building construction.
  • the profiles 21-25 may be mounted either to a ceiling, one or more walls, or may form a separate standing grid as is shown in figure 6 .
  • Such profiles are usually available in widely varying designs. They may be suspended to the building construction using standard suspension means, they are available in one or more standard sizes, having recesses 6, 7 at pre-set distances from each other. It is also possible to use as a suspension grid a bandraster system.
  • the preferred profile for use with the baffle system of this invention is a profile which is made of one part, as in that case the vertical part of the profile containing the attachment means is a so-called double web system.
  • the baffle elements 1, 11 may depend vertically from the ceiling, by having the baffle elements suspended through either the first and second attachment means 4, 5 or the fifth and sixth attachment means 14, 15 or a combination of both.
  • the baffle elements 1, 11 may however also be fixed in an angle of 90° or any other value with respect to the ceiling.
  • the baffle elements may also be grouped in so-called islands, where a first group of baffle elements 1 extends under a first angle and a second group of baffle elements 11, extends under a second angle with respect to the ceiling ( figure 5 ). 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. As can be seen from figure 5 , baffle elements may extend parallel to the longitudinal direction of the profiles, in which case the baffle system functions as a ceiling.
  • baffle elements may be mounted in islands, a first island 30 comprising one or a plurality of vertically depending baffle elements, a second island comprising one or a plurality of horizontal baffle elements 33, a third island comprising a plurality of baffle elements which slant in a first direction, a fourth island comprising a plurality of baffle elements which slant in a second direction, a sixth island 36 comprising a plurality of baffle elements depending in cross direction.
  • Figure 5B shows that a multiplicity of baffle elements mounted to the same first and second profile may take various positions.
  • a baffle system which shows a high versatility, the construction and sound absorbing properties of which are easily adaptable to the local circumstances.
  • the high versatility is attributed to the incorporation of a suspension grid to which the baffle elements are to be suspended, the suspension grid being indirectly mounted to the building construction by means of suspension hangers.
  • a suspension grid is in general used in the construction of suspended ceiling systems, to which rather light weight ceiling tiles are mounted.
  • the suspension grid is used as an attachment system for mounting the baffle elements, which besides an aesthetic effect have the functional effect of providing sound absorption. Nevertheless, the suspension system may locally still be used to construct a local suspended ceiling.
  • the baffle system may include all further elements which normally are associated with a suspended ceiling, such as lightning, electricity, air-conditioning devices, partitions, whereby the suspended ceiling may extend at different levels with respect to the building construction.
  • the usual profiles for constructing a suspended ceiling may be used.
  • the application of the baffle system of this invention is not limited to a system which should suspend from a ceiling, as it may also be mounted to a vertical wall, to a wall extending in any other direction, along windows etc. Besides this it may also be used as an independently standing construction.
  • the above described baffle system is suitable for use with a suspension grid which may or may not follow the shape of the ceiling.
  • the hinged mounting of the baffle elements, and the individual attachment of each baffle element to the suspension grid facilitates accessibility of the plenum above the baffle system.
  • consecutive baffle elements are interconnected, as a consequence of which a multiplicity of baffle elements must be disconnected to gain access to the plenum.
  • the hinged connection allows a direct mounting of the baffle elements to the suspension grid, thus minimizing the number of interfering components.
  • the hinged connection contributes to improving the sound absorbing properties of the baffle system as the baffle elements may be mounted and fixed such that they extend in any required direction.
  • FIG. 1 The above described properties are illustrated in figure 1 , where a number of baffle elements 1 extend virtually parallel and depend in height direction from a suspension grid suspended to the ceiling of a building construction.
  • the shape of the plane formed by the bottom sides 26 of the baffle elements 1 may be varied.
  • 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.
