DETAILED DESCRIPTION

[0035] With reference to the figures, there is shown a booth 1 according to an embodiment of the present invention. The booth is soundproof. The booth is freestanding and comprises upstanding peripheral walls 2 and a roof 3. One of the walls 2 defines an opening 5 that is closed by a door 6. The walls 2 and the roof 3 enclose a space to be ventilated by a ventilation system. The ventilation system comprises a fan 7 for providing an airflow, an air inlet 8 through which air enters the space to be ventilated from outside the booth, and an air outlet 9 through which air exits the space to be ventilated to outside the booth. The air outlet comprises a first air outlet aperture 9a and a second air outlet aperture 9b and an air outlet channel 9c extending between the first and second air outlet apertures 9a, 9b, wherein the air outlet channel 9c is provided at least partly inside one of the walls of the booth.

[0036] There is preferably an indirect air path from the first air outlet aperture 9a to the second air outlet aperture 9b, as best shown in FIG. 3. The first air outlet aperture 9a and the second air outlet aperture 9b are preferably vertically spaced from one another. As discussed in greater detail below, in the present arrangement, the second air outlet aperture 9b is located in the roof 3 whilst the first air outlet aperture 9a is located adjacent a base of one of the walls 2. In an alternative arrangement, the first and second air outlet apertures may be provided on different walls 2 of the booth, wherein they could be at the same vertical height in this case.

[0037] In the present arrangement two of the walls 2 are provided with air outlet channels 9c, as best seen in FIG. 3. It is to be noted that a single wall only may be provided with an air outlet channel or any number of additional walls may also be provided with air outlet channels. The present invention is not to be limited in this regard and may be dependent on the shape of the booth and/or the specific number of walls the booth has.

[0038] Whilst in the present arrangement the booth has four walls 2 (and thereby four sides) it could have more or less walls/sides in alternative arrangements. In alternative arrangements the booth could take numerous forms, including triangular, hexagonal or octagonal-shaped or otherwise, wherein adjacent sides would be at an oblique angle to one another rather than perpendicular to one another as in the present arrangement. More than this, the booth could be constructed with curved walls.

[0039] The form of the one or more air outlet channels may depend on the structure of the booth. In the present arrangement, the walls comprise inner and outer panels 10, 11 fixed to vertical support members (not shown), which vertical support members preferably form part of a sub frame. The vertical support members may be attached to a base 12. The air channels 9b are defined at least in part by spaces between the panels, as seen in FIGS. 2 and 3. In alternative arrangements, the air channels may be formed by ducting or otherwise. Further, the air channels may be formed into a single layer of a sandwich-type wall structure. In arrangements provided with a base 12, particularly but not exclusively arrangements where the base is provided at the periphery of the booth only, as seen in FIG. 2, the first air outlet aperture may be provided in or adjacent the base in a region of the base that extends along a basal edge of the respective wall comprising the air outlet channel 9c.

[0040] Any or all of the walls 2 may comprise at least one inner panel and at least one outer panel 10, 11, which oppose one another and comprise respective inner and outer faces of the respective wall 2. With the inner and outer panels 10, 11 mounted to vertical support members, the vertical support members may comprise either a plurality of vertically spaced lugs or a plurality of vertically spaced hooks that are provided between the inner and outer panels 10,11, wherein the inner and outer panels 10, 11 each comprise a corresponding plurality of the other of the vertically spaced hooks or lugs, and the lugs and hooks engage with one another to support the first and second panels on the support element. It should be appreciated that numerous other means of fixing panels to the sub frame will be possible, as will be readily appreciated by those skilled in the art. The present invention is not to be limited in this regard.

[0041] Whilst in the present arrangement, the walls comprise the inner and outer panels 10, 11 fixed to vertical support members, which may form part of a sub frame, it should be appreciated that the present invention is applicable to booths that have alternative structures, such as booths formed by attaching complete composite or laminate panels to a base, or otherwise. The present invention is not to be limited to the specific structure of the depicted arrangement.

[0042] The panels 10, 11 may take any suitable form. They will preferably have sufficient rigidity to prevent sagging. The inner panels may comprise padded fabric panels to provide for acoustic damping. The inner panels will preferably abut one another, resiliently, to aid in soundproofing. The outer panels may be rigid panels and could be formed from wood, plastic or otherwise. The inner and outer panels could be formed from the same materials or from different materials. There may be sound proofing panels or materials provided between the inner and outer panels. These may be included or omitted in dependence on the acoustic properties of the inner and outer panels.

[0043] The walls 2 may comprise multiple smaller inner and outer panels or a single inner panel and a single outer panel per wall. Multiple panels may be arranged to form a substantially flush surface. The use of multiple smaller panels will allow for more compact transportation or storage when the booth is dismantled. In the present arrangement, the walls each comprise a single outer panel.

[0044] The roof may have a similar structure to the walls and this may comprise any of the above described possible wall structures. In the depicted arrangement, the roof 3 comprises inner and outer panels 13, 14 like the walls 2. There is a single inner panel and a single outer panel, although this need not be the case. Where the second air outlet aperture 9b is provided in the roof, as in the depicted arrangement, the air outlet channel 9c may be continuous between the wall and the roof, as shown. With inner and outer panels, the portion of the air outlet channel 9c in the roof is provided between the inner and outer panels, as best seen in FIG. 3.

[0045] It is preferable, to further enhance sound proofing, that the outer panels 11 of the walls 2 and the outer panel 14 of the roof 3 are sealed to one another to provide a sealed outer layer.

[0046] The air inlet 8 is preferably provided in the roof, as shown. The air inlet may comprise a first air inlet aperture 8a, a second air inlet aperture 8b and an air inlet channel 8c extending between the first and second air inlet apertures, wherein the air inlet channel 8c is provided inside the roof. There is preferably an indirect air path from the first air inlet aperture 8a to the second air inlet aperture 8b. In such an arrangement, the first air inlet aperture 8a and second air inlet aperture are offset from one another (horizontally). In alternative arrangements, there could be alignment between the first and second air inlet apertures 8a, 8b. The air inlet 8 is provided with the fan 7. In the present arrangement, the fan is provided behind the second air inlet aperture 8b. It could, of course be arranged otherwise.

[0047] In the present arrangement, there is only a single fan shown. In alternative arrangements there could be multiple fans provided. There could for example, be inlet and outlet fans provided.

[0048] In the present arrangement, comprising an air inlet channel 8c and an air outlet channel 9c, these channels are isolated from one another so that airflows into and out of the internal space to be ventilated are separated. In the present arrangement, gaskets 15 are provided in the space between the inner and outer panels 13, 14, which provide suitable isolation. In dependence on the form of the inlet and outlet 8, 9 and/or the form of the walls and the roof 2, 3, other means of separating airflows may be provided, as will be readily appreciated by those skilled in the art.

[0049] It is preferable, as shown in FIG. 1, that there is a plurality of the first air inlet apertures 8a. At least two of the first air inlet apertures 8a being spaced from one another and directing airflow in directions away from one another. It is also preferable that there is a plurality of the second air outlet apertures 9b, at least two of the second air outlets 9b being spaced from one another and directing airflow in directions away from one another. In the present arrangement, the first air inlet apertures 8a and the second air outlet apertures 9b are arranged along peripheral edges of the roof 3. The first air inlet apertures 8a are provided along first and second opposed peripheral edges and the second air outlet apertures are provided along third and fourth opposed peripheral edges. The first air inlet apertures 8a and the second air outlet apertures 9b are directed outwards, such that the direction of airflow for air drawn into the opposed first air inlet apertures 8a is at substantially 180 degrees to one another and the direction of airflow for air exiting the second air outlet apertures is at substantially 180 degrees to one another. For such purposes the first air inlet apertures 8a and the second air outlet apertures 9b preferably comprise directional vents. They may be adjustable so that airflow direction of any of the apertures may be adapted to the environment in which the booth is placed.

[0050] Whilst the apertures are shown to be annular, they may take any alternative form, they could be strip like in shape for example. Moreover, whilst in the present arrangement there are two first inlet air apertures 8a and two second outlet air apertures 9b, there could be more or less inlet and/or apertures of the same or differing form and offering fixed or variable directionality of airflow. The apertures also need not be provided along the peripheral edges.

[0051] FIG. 3 shows the airflow path for the ventilation system. Air is drawn into the booth through the air inlet 8 by the fan 7 and ejected via the air outlet 9. In the present arrangement, (cooling) air is drawn into the booth from the front and rear of the booth 1 through the first inlet air apertures 8a, it is pushed out of the second air outlet aperture 8b by the fan 7 and then is drawn out of the internal space of the booth through the first air outlet apertures 9a, it travels through the air outlet channel 9c and is pushed out of the left and right sides of the booth 1 through the second air outlet apertures 9b. With such an arrangement, booths 1 may be placed next to one another and/or against a wall without interrupting the flow of air. Moreover, inlet and outlet airflows are separated to avoid drawing warm expelled air into any of the booths.

[0052] A benefit of drawing air up through the walls, particularly walls such as the left and right walls of the booth of the present arrangement that are not provided with the door is that the exiting airflow may be passed behind electrical equipment to draw away heat. For example, suitable openings in the inner panel 10 may be provided, with any additional ducting required, to draw the air across the back of a computer monitor, or otherwise. In one arrangement, the additional ducting may be provided in a frame for a monitor, or other electrical device, so that air travelling vertically up through the air outlet channel 9c is diverted from the air outlet channel 9c into the frame via a first opening in the inner panel 10 and out of the frame and back into the air outlet channel through a second opening in the inner panel 10 that is vertically above the first opening, the frame defining a channel between the first and second openings. The electrical device will be exposed to the channel in the frame, or other suitable structure.

[0053] The invention has been described above with reference to specific embodiments, given by way of example only. It will be appreciated that many different arrangements of are possible within the scope of the appended claims.
