Description

Acoustic Room Enclosure

FIELD OF THE INVENTION

The present invention relates to a ceiling for an acoustic room enclosure, an acoustic room enclosure and to a method of acoustically protecting a room enclosure. In particular, the present invention relates to a ceiling for an acoustic office enclosure, an acoustic office enclosure and to a method of acoustically protecting an office enclosure.

BACKGROUND TO THE INVENTION

In recent years more flexible working practices have seen an increase in the number of open plan offices. However, although the open plan office has a number of key advantages in terms of a flexible and efficient use of space, it also poses a number of significant disadvantages.

Noise levels in open plan offices can be high and noise intrusions impact on a worker's productivity. The open plan nature of the office also affects workers' privacy, with discussions and telephone calls being overheard by those seated nearby.

Large open plan offices may therefore have separate rooms for users requiring a greater degree of privacy. These rooms are generally conventional rooms located around the periphery of the open plan office. Alternatively, these rooms may be located elsewhere in the office building. Accordingly, such private rooms incur the costs, delays and structural requirements of building permanent rooms.

One alternative is to have screens within the open plan area to provide a more private area within the open plan area. However, such screens may not provide the required degree of privacy. One further alternative is to build a self contained room including an enclosed ceiling within the open plan area. This self contained room including the ceiling would then provide a completely self contained volume and atmosphere. Accordingly, such rooms may need to be assessed for fire regulations. These rooms may require independent cooling and heating systems and these rooms may also require independent smoke detectors and fire controlling apparatus and equipment.

It is an aim of the present invention to overcome at least one problem associated with the prior art whether referred to herein or otherwise.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

As shown in Figure 1 and Figure 2, the present invention provides an acoustic room enclosure 10 and specifically an acoustic office enclosure 10. The acoustic room enclosure 10 is a self contained room which can be located within a larger space within an office or similar environment. In particular, the acoustic room enclosure 10 may be located within an open plane office in order to provide an acoustically protected environment for users. This acoustic room enclosure 10 provides an environment which enables users to have private conversations. This acoustic room enclosure 10 may be used for meetings, to make telephone calls from an open plan environment without the background noise or to act as a quiet room to enable users to concentrate without the surrounding noise.

The acoustic room enclosure 10 comprises a peripheral wall 12 and a ceiling assembly 14. The ceiling assembly 14 of the present invention comprises a frame system which is completely and solely supported by the peripheral wall structure 12 of the acoustic room enclosure 10. The ceiling assembly 14 comprises a number of acoustic ceiling panels 16 which are suspended from the frame system.

One aim of the present invention is to provide an improved self contained room enclosure for use within an open plane office environment. In order to achieve this and other aims, the acoustic ceiling panels 16 are supported to provide a gap 18 between the ceiling panels 16 and the peripheral wall of the acoustic room enclosure 10. This gap 18 directly teaches against prior art self contained room enclosures having sealed ceiling assemblies to prevent the transmission of noise from and to the inner environment of the room enclosure. However, the use of a sealed or closed ceiling introduces further problems regarding health and safety and specifically fire regulations. In addition, a sealed ceiling or closed ceiling means that the environment and atmospheric conditions within the enclosure require independent control and monitoring apparatus and systems.

The gap 18 is defined between the ceiling panels 16 and the peripheral wall. In addition, the gap 18 is also defined between adjacent ceiling panels 16. The gap 18 between adjacent ceiling panels 16 may be arranged to be the same or greater than or less than the gap 18 between the ceiling panels 16 and the peripheral wall.

Naturally, the provision of such a gap 18 would appear to enable sound to be transmitted to and from the protected environment of the acoustic room enclosure 10. However, the acoustic ceiling panels 16 absorb a proportion of the noise and the gap 18 enables only a proportion of the noise to be transmitted therethrough whilst avoiding the problems of closed or sealed ceiling systems. The gap is arranged to have dimensions that optimise the diffraction of sound with frequencies below 2000 Hz. The maximum gap may be selected to correspond with or to be correlated to the wavelength of frequency of interest. This aims to optimise the diffraction of sound over the absorptive surface. The maximum gap may be 200 mm.

The ceiling assembly 14 comprises a frame having a number of elongate frame members 20. The frame members 20 are arranged to be solely and completely supported on the upper periphery 22 of the peripheral wall 12 of the acoustic room enclosure 10. In particular, the frame members 20 have first wall engaging means at a first end 22 and second wall engaging means at a second end 24. The frame members 20 have a central elongate linear section 26 extending between the two ends 22, 24 of the frame members 20. Accordingly, the frame members 20 are solely supported by the peripheral wall 20 and the frame members extend across the top of the acoustic room enclosure 10 such that either end 22, 24 of the frame members 20 are supported on opposing sections of the peripheral wall 12.

The ceiling assembly 14 inciudes suspension means in order for the acoustic ceiling panels 16 to be suspended from the frame members 20.

The suspensions means includes flexible suspension members 28 and, in the preferred embodiments, the suspension members 28 comprise sections of wire or cable.

An upper end of the suspension member 28 includes first suspension securement means. This first suspension securement means enables the suspension members 28 to be secured to the frame members 20. In the preferred embodiment, the upper end of the suspension member 28 comprises a threaded shaft which is engaged with a corresponding threaded hole, sleeve or aperture provided on the frame member 20 and preferably on the central linear section 26 of the frame member 20. The frame member 20 may include several female securement means to engage with corresponding male securement means provided on the upper end of the suspension members 28. Accordingly, the frame system may enable the suspension members 28 to be secured at set or predetermined positions along the length of the frame members 20. In alternative embodiments, the suspension members 28 may be secured at any position along the length of the frame members 20.

Similarly, the suspension members 28 have include second suspension securement means at a lower end thereof. The second suspension securement means are arranged to secure the ceiling panels 16 to the suspension members 28. In particular, the second suspension securement means comprise panel anchor members which include an engagement portion. The engagement portion may include a helical or curved projection which can be urged into the material of -11 -the ceiling panel 16. For example, the engagement portion may be rotated or screwed into the upper surface of the ceiling panel 16 in order to secure the ceiling panel to the suspension member 28.

The ceiling panels 16 may comprise acoustic ceiling panels which are arranged to absorb and diffract the wound energy from within the acoustic room enclosure 10.

As previously explained, the ceiling panels 16 are suspended in order to create a gap 18 between the ceiling panels and the peripheral wall 12. This gap is selected to optimise the diffraction of sound energy over the frequencies of interest, i.e. the audible frequencies.

In the preferred embodiment, the ceiling panels 16 are suspended such that the lower surfaces of the ceiling panels 16 locate above the upper surfaces of the peripheral wall 12. This effectively creates a vertical gap which enables the atmospheric conditions within the acoustic room enclosure 10 to equate to the atmospheric conditions outside the acoustic room enclosure 10. Alternatively, the ceiling panels 16 may be suspended such that the lower surfaces of the ceiling panels 16 locate below the upper surfaces of the peripheral wall. This prevents a vertical gap being created and may increase the acoustic absorbing properties of the room.

Furthermore, from a plan view, the peripheral edges of the ceiling panels 16 are spaced from the inner edges of the peripheral wall 12. In the circular embodiment shown in Figure 1, this creates an annular gap around the periphery of the acoustic room enclosure 10 between the ceiling assembly 14 and the peripheral wall 12.

In addition, the ceiling assembly 14 includes a plurality of acoustic ceiling panels 16 and these ceiling panels are suspended such that there is a gap between adjacent ceiling panels 16. This gap encourages and enables the environment within the acoustic room enclosure 10 to reach equilibrium with the atmospheric conditions outside the acoustic room enclosure 10. Accordingly, the gaps prevent the requirement for extra or additional heating or air conditioning apparatus and equipment. In addition, the provision of such gaps would enable fire detecting and fire controlling apparatus to be effective for the acoustic room enclosure. For example, smoke detectors and sprinkler systems in the open plane office would also be effective or sufficient for the area within acoustic room enclosure 10.

The peripheral wall 12 of the acoustic room enclosure 10 is constructed from panels and preferably acoustic panels or at least partially acoustic panels.

Accordingly, the complete acoustic room enclosure 10 is a self contained self supporting structure which can be located within any environment having sufficient space. The acoustic room enclosure may be of any size or shape, for example circular, as shown in Figure 1, or rectangular, as shown in Figure 2.

The frame system of the ceiling assembly 14 is arranged to suspend an array of ceiling panels 16 in a spaced arrangement. Each ceiling panel 16 may be secured between two adjacent and parallel frame members 20. Each pair of adjacent frame members 20 may be arranged to suspend a number of ceiling panels 16 spaced along the longitudinal length of the frame members 20.

As shown in Figure 4 to Figure 7, a frame member 20 includes a central linear section 26 which extends between a first end 22 and a second end 24. The frame member 20 comprises a tubular member and, in particular, comprises a hollow member with a substantially square profile with rounded edges.

The frame member 20 includes a first end section 22 and a second end section 24. The end sections 22, 24 are substantially identical. The end sections 22, 24 comprise curved or arcuate sections which are arranged to extend inwardly and upwardly from the top surface of the peripheral wall 12 of the acoustic room enclosure 10. Accordingly, the end sections create a gap vertically and also create a gap horizontally. Specifically a gap is created in a vertical plane and in a horizontal plane. This gap in both planes maximises the airflow between the inner and outer environments.

The lower end of the end sections 22, 24 include wall engagement means in order for the frame member 20 to be solely supported between two locations on the peripheral wall 12.

The wall engagement means comprises a channel section 32 provided on the lower end of the end sections 22, 24. The channel section 32 includes a support surface 34, an inner abutment surface 35 and an outer abutment surface 36. In use, the support surface 34 rests on top of the peripheral wall 12 whilst the inner abutment surface 35 locates adjacent the inside of the peripheral wall 12 and the outer abutment surface 36 locates adjacent the outside of the peripheral wall 12.

The ceiling assembly 14 also includes securing elements to retain the end sections 22, 24 of the frame members 20 in position on the top of the peripheral wall 12. These securing elements may include any suitable securement element, for example a screw or nut and bolt system.

Figure 8, Figure 9 and Figure 10 show alternative mounting and fixing arrangements for securing a frame member 20 to a peripheral wall 12.

Figure 8 shows the end section 22 of a frame member 20 having two securement apertures 40 in a transition plate 42 through which bolts 44 can pass into respective securement apertures 46 provided on a rail 48. The rail 48 is mounted to the top of a peripheral wall section 12 and, accordingly this arrangement enables the frame member 20 to be quickly and easily secured to the peripheral wall 12.

Figure 9 shows the end section 22 of a frame member 20 showing the securement of the transition plate 42. The transition plate 42 is simply bolted to the end of the frame member 22 with a single bolt 50.

Figure 10 shows an arrangement for fixing or securing the frame member 20 to a -14 -wall. The frame member 20 includes an end plate 52 with two apertures 54 provide thereon. Two wood screws 56 are arranged to extend through these apertures 54 in order to locate within appropriate wall plugs provided in the wall.

As shown in Figure 11, the frame member may comprise an extendable member including a first section 60 and a second section 62.The two frame sections 60, 62 may be secured to each other using bolts 64 and respective apertures 66. This adjustable and extendable bar 62 enables the ceiling to be easily adapted for acoustic rooms of differing sizes and shapes. The frame member is effectively telescopic with the second frame section 62 sliding into and out of the first frame section 60.

In addition, as shown in Figure 12, a first frame member 70 may be secured to a perpendicularly arranged second frame section 72. This fixing may simply comprise a bolt 76 and respective securement apertures 74. This arrangement may be of particular use above a doorway, as shown in Figure 2. In this arrangement, it can be seen that without a transverse frame section 72 there would be no structural position at which to secure the end of the longitudinal first frame section 70.

Overall, the present invention provides a self contained and self supporting acoustic room enclosure 10 in which the ceiling 14 includes a number of acoustic ceiling panels 16 that provide gaps 18 in the ceiling 14 to enable the acoustic room enclosure 10 to benefit from the existing apparatus and systems located externally for air, heating, cooling, smoke and fire detection and control etc. The gap aims to diffract the sound energy and to thereby reduce and inhibit the transmission of audible sounds. In particular, the gap may have a maximum dimension of 200 mm in order to diffract sound for frequencies below 2000 Hz.
