DETAILED DESCRIPTION OF THE FIGURES

[0041] FIG. 1 generally shows a spraying and baking vehicle enclosure 1, formed by two transportable modules respectively referenced 2 and 3. The transportable modules may be identical. However, in certain embodiments, the modules may differ from one another, for example in certain embodiments it may be envisaged for only one of the modules to incorporate an air handling unit whilst the other accommodates more generous storage facilities.

[0042] Nevertheless, since in preferred embodiments both modules are identical, the detailed description will be provided with respect to transportable module 2. Transportable module 2 incorporates a housing 4 with a front wall 5 (see FIG. 2), a rear wall 6 located at the opposite extremity of the housing, a first side wall 7 located opposite to a second side wall 8. Walls 5, 6, 7 and 8 are deemed to be external walls. One or more doors may be provided to access the housing. For example, the doors 9, 10, 11 and 12 are provided, which may be simple hinged panels. Within the housing, an air handling unit generally referenced 13 may be provided adjacent to the second side wall 8 and may itself be provided in its own segregated compartment. This allows a space 14 between the air handling unit and the first side wall 7 which may be employed for storage purposes. During transport for example, a roller shutter, such as roller shutter door 15 may be rolled and stowed away in space 14. An internal partition 16 may also be provided to segregate the air handling unit from a welfare area which may be used as an office, toilet and for any other purpose suitable for the application envisaged.

[0043] The air handling unit employs a fan 17 which may draw fresh air in through a fresh air duct 18 and through a heat exchanger 19 for heating the air at either a level suitable for a spraying temperature within the enclosure or a baking temperature as appropriate. The heated air may then flow through a duct 20, which may be incorporated into the deployable side wall 21. In the upper portion of the deployable side wall 21, a vent 22 may be provided through which heated air enters the vehicle receiving volume of the enclosure. The air unit comprises an extraction duct 23 located adjacent to the floor of the housing, which causes the air to circulate or flow from upper regions of the vehicle enclosure to the bottom region. Extracted air may then be passed through a number of filters in order to remove contaminants prior to being expelled through a duct or chimney 28. In certain embodiments, the chimney may solely be used for any gaseous emissions produced by the heat exchanger. The heat exchanger 19 may be a direct fired gas burner or any other appropriate kind of heat exchanger. In such embodiments, the heat exchanger may also be equipped with a refrigeration cycle which may be employed to cool the circulated air rather to heat it.

[0044] During transportation the module 2 can carry on the roof of its housing both side wall 20 and roof portion 24. In preferred embodiments, side wall 21 is stacked on top of the housing whilst roof portion 24 is itself stacked on side wall portion 21. In preferred embodiments, side wall portion 21 is pivotally secured to an upper portion of the housing in order to be able to change configuration between the stacked configuration of FIG. 4 and the deployed configuration of FIG. 1. A hinge or pivot point may be provided between the side wall portion and the housing. Similarly, roof portion 24 is pivotally secured to the uppermost extremity of side wall 21 whereby it may be transported in a stacked configuration as shown in FIG. 4 whilst being deployed as projecting laterally as shown in FIG. 1. In practice, the displacement of the stacked side wall 21 and the roof portion 24 may be driven by an actuator. The actuator may take the form of a hydraulic ram such as hydraulic rams 25 and 26. In one embodiment, the side wall 21 is initially pivoted by 90 degrees from the configuration of FIG. 4 to the configuration of FIG. 1 whilst at the same time carrying the stacked roof. Alternatively, the roof portion may be first deployed by rotation from its stacked configuration to an erect position and then the side portion 21 could then be rotated. Embodiments are envisaged to cover either sequence of deployment. Once the side wall and roof portions are in their deployed positions and the extremities abut one another, these may be secured into position by bolting, welding or any other appropriate attachment methodology. Alternatively, the extremities of the roof portion may be designed with appropriate tongue and groove mechanisms to align and interlock once deployed. Once deployed in the configuration of FIG. 1 the roller blinds may be placed in the respective entrance and exit to the enclosure and chimneys 28 may be deployed as appropriate. Whilst not shown in the figures, a floor portion for the vehicle receiving portion may also be deployed. For example, the floor portion may be placed against the inner side wall of the housing and may therefore be deployed by rotation by 90 degrees should a floor portion be required in any particular embodiment.

[0045] In a preferred embodiment, the air handling unit may raise the temperature of the incoming air at a temperature which could be as low as −5 degrees Celsius to 22 degrees Celsius to enable a suitable spray temperature to be achieved. The spray temperature is preferably between 15 and 30 degrees Celsius. Similarly, on the bake mode of operation, a temperature in excess of 50 degrees Celsius is envisaged over the entire vehicle containing enclosure to ensure complete curing of 2 pack materials. Preferably, the baking mode operations reaches a temperature between 50 and 75 degrees Celsius. In a preferred embodiment, the temperature reached is of 60 degrees Celsius. These temperatures may also be reached dependent upon the environmental conditions surrounding the enclosure by employing a refrigeration circuit in embodiments where one is provided.

[0046] Whilst the primary embodiment shows the combination of two oppositely disposed modules to form the vehicle receiving enclosure, further embodiments envisage a succession of modules of this kind which may be preferably aligned in the longitudinal direction of the enclosures.

[0047] FIG. 5 generally shows a spraying and baking vehicle enclosure 101, formed by two transportable modules respectively referenced 102 and 103. The transportable modules may be identical. However, in certain embodiments, the modules may differ from one another, for example in certain embodiments it may be envisaged for only one of the modules to incorporate an air handling unit whilst the other accommodates more generous storage facilities.

[0048] Nevertheless, since in preferred embodiments both modules incorporate an air handling unit, the detailed description will be provided with respect to transportable module 102. Transportable module 102 incorporates a housing 104 with a front wall 105 (see FIG. 6), a rear wall 106 located at the opposite extremity of the housing, a first side wall 107 located opposite to a second side wall 108. Walls 105, 106, 107 and 108 are deemed to be external walls. One or more doors may be provided to access the housing. For example, the doors 110, 111 and 112 are provided, which may be simple hinged panels. Within the housing, an air handling unit generally referenced 113 may be provided adjacent to the second side wall 108 and may itself be provided in its own segregated compartment. This allows a space 114 between the air handling unit and the first side wall 107 which may be employed for storage purposes. During transport for example, a roller shutter, such as roller shutter door 115 may be rolled and stowed away in space 114. An internal partition 116 may also be provided to segregate the air handling unit from a welfare area which may be used as an office, toilet and for any other purpose suitable for the application envisaged.

[0049] The air handling unit employs a fan 117 (see FIG. 5) which may draw fresh air in through a fresh air duct and through a heat exchanger 119 for heating the air at either a level suitable for a spraying temperature within the enclosure or a baking temperature as appropriate. The heated air may then flow through a duct 120, which may be incorporated into the deployable side wall 121. In the upper portion of the deployable side wall 121, a vent 122 may be provided through which heated air enters the vehicle receiving volume of the enclosure. The air unit comprises an extraction duct 123 located adjacent to the floor of the housing, which causes the air to circulate or flow from upper regions of the vehicle enclosure to the bottom region. Extracted air may then be passed through a number of filters in order to remove contaminants prior to being expelled through a duct or chimney 128. In certain embodiments, the chimney may solely be used for any gaseous emissions produced by the heat exchanger. The heat exchanger 119 may be a direct fired gas burner or any other appropriate kind of heat exchanger. In such embodiments, the heat exchanger may also be equipped with a refrigeration cycle which may be employed to cool the circulated air rather to heat it.

[0050] During transportation, the module 102 can carry on the roof of its housing both side wall 120 and roof portion 124. In preferred embodiments, side wall 121 is stacked on top of the housing whilst roof portion 124 is itself stacked on side wall portion 21. In preferred embodiments, side wall portion 121 is pivotally secured to an upper portion of the housing in order to be able to change configuration between the stacked configuration of FIG. 8 and the deployed configuration of FIG. 5. A hinge or pivot point may be provided between the side wall portion and the housing. Similarly, roof portion 124 is pivotally secured to the uppermost extremity of side wall 121 whereby it may be transported in a stacked configuration as shown in FIG. 8 whilst being deployed as projecting laterally as shown in FIG. 5. In practice, the displacement of the stacked side wall 121 and the roof portion 124 may be driven by an actuator. The actuator may take the form of a hydraulic ram such as hydraulic rams described in previous embodiment. In one embodiment, the side wall 121 is initially pivoted by 90 degrees from the configuration of FIG. 8 to the configuration of FIG. 5 whilst at the same time carrying the stacked roof. Alternatively, the roof portion may be first deployed by rotation from its stacked configuration to an erect position and then the side portion 121 could then be rotated. Embodiments are envisaged to cover either sequence of deployment. Once the side wall and roof portions are in their deployed positions and the extremities abut one another, these may be secured into position by bolting, welding or any other appropriate attachment methodology. Alternatively, the extremities of the roof portion may be designed with appropriate tongue and groove mechanisms to align and interlock once deployed. Once deployed in the configuration of FIG. 5, the roller blinds may be placed in the respective entrance and exit to the enclosure and chimneys 28 may be deployed as appropriate. Whilst not shown in the figures, a floor portion for the vehicle receiving portion may also be deployed. For example, the floor portion may be placed against the inner side wall of the housing and may therefore be deployed by rotation by 90 degrees should a floor portion be required in any particular embodiment. Alternatively, in preferred embodiments, no floor is provided between the modules so that the structure may for example straddle railway tracks or other vehicle carrying structures.

[0051] A number of support beams such as longitudinal beams 129 and 130 may be provided as part of the roof of the module 102. In further embodiments, a plurality of cross beams are also provided such as laterally extending beam 131. These are particularly advantageous in carrying the side wall portion 121 and roof portion 124 as shown in FIG. 8. The stacked configuration shown in FIG. 8 doesn't cover the entire surface of the roof. A space is provided around the perimeter of the stack between the perimeter of the stack and the perimeter of the roof of the module 102. This removes the overhang which was considered in the first embodiment. Side walls are also equipped with longitudinal beams such as beams 132 and 133, with vertical beams or with a combination of longitudinal beams and vertical beams (along preferably orthogonal axes). The modules can thus be readily transported and carry during transportation and when fully deployed both the internally provided air handling unit and the stack formed by the side wall portion and the roof portion. In preferred embodiments, a combination of beams in orthogonal directions are provided on each one of the faces of a module including its floor.

[0052] In a preferred embodiment, the air handling unit may raise the temperature of the incoming air at a temperature which could be as low as −5 degrees Celsius to 22 degrees Celsius to enable a suitable spray temperature to be achieved. The spray temperature is preferably between 15 and 30 degrees Celsius. Similarly, on the bake mode of operation, a temperature in excess of 50 degrees Celsius is envisaged over the entire vehicle containing enclosure to ensure complete curing of 2 pack materials. Preferably, the baking mode operations reaches a temperature between 50 and 75 degrees Celsius. In a preferred embodiment, the temperature reached is of 60 degrees Celsius. These temperatures may also be reached dependent upon the environmental conditions surrounding the enclosure by employing a refrigeration circuit in embodiments where one is provided.

[0053] Whilst the primary embodiment shows the combination of two oppositely disposed modules to form the vehicle receiving enclosure, further embodiments envisage a succession of modules of this kind which may be preferably aligned in the longitudinal direction of the enclosures.

[0054] FIG. 9 shows a further embodiment where a spray and bake enclosure is formed of at least one transportable module. An air handling module 201 may be provided which is of smaller dimensions than two further modules such as module 202 and 203. Air handling module 201 may comprise 6 faces and be substantially cubic. The air handling module may have two side walls, a roof and a floor and potentially having one or both of the front and/or rear faces open. In one embodiment, both front and rear faces respectively 204 and 205 are open. The side faces, the roof and the floor being relatively rigid in construction in order to be able to carry the air handling unit, which may include an air conditioning unit or a heater in order to cool or heat an adjacent enclosure such as enclosures 202 and 203. A junction member 206 may be provided between the air handling unit and the enclosure 202. A further junction member 207 may be provided between the air handling unit and a further enclosure such as enclosure 203. The junction members may incorporate a frame formed of two upright members and two laterally extending members which combine to provide a robust connection between the air handling unit and adjacent enclosures. One or both adjacent enclosures may be suitable to accommodate a vehicle for spraying and baking. Once assembled the air handling unit, the or each junction members and the vehicle enclosure, these may be suitable for transportation as a single piece. Alternatively, these may be dismantled for transportation in two or more parts.

[0055] In one embodiment, the air handling unit is provided centrally and may be configured to heat either of the adjacent vehicle enclosures. The air handling unit may for example be able to recycle the heated air from a first unit into a second adjacent unit in order to allow more rapid temperature rises suitable for baking paint. For example, in a mode of operation, a vehicle may be prepared, and spray painted at a relatively low or near ambient temperature in a first enclosure. Once spraying is completed the air handling unit may be configured to heat the temperature in said first enclosure to a higher temperature in order to facilitate baking of the paint. In the second adjacent enclosure, a vehicle may be prepared and sprayed at relatively low or ambient temperature and thereafter once the baking has been completed in the first enclosure, a pump may force the heated air from the first enclosure into the second enclosure in order to reach a temperature suitable for baking. By so doing, the first vehicle enclosure may also be replenished with fresh air for the painting of a subsequent vehicle whilst the heated air from the first enclosure may serve as the necessary temperature for heating the second enclosure. The air handling unit may incorporate an exhaust system to draw in from either of the adjacent enclosures as appropriate.

[0056] In further embodiments, the air handling module may operate in conjunction with 3 or 4 adjacent vehicle modules and a controller may be provided to cause the flow of air from any of the vehicle enclosure to any other one of the vehicle enclosures.

[0057] The junction members may include I- or T- beams, box sections, or plates which are either bolted or welded to the frames of the respective adjacent modules.

[0058] FIGS. 10A and 10B show an embodiment of a vehicle enclosure which is relatively compact when transported on a transporter as shown in FIG. 10A and may then be expanded to form a combined air handling unit and vehicle enclosure as shown in FIG. 10B. An air handling unit 208 is provided to house a heater or a cooler, and/or any appropriate filtration means which would draw air from an adjacent vehicle enclosure prior to exhausting into the environment in the vicinity of the unit. The air handling unit is secured to one or more deployable side walls such as side walls 209, 210, 211 and 212.

[0059] During transportation, side walls 209, 210, 211 and 212 rest against a portion of the air handling unit as shown in FIG. 10A. In the view presented as FIG. 10A, side wall 212 is folded back or located underneath the air handling unit whilst side wall 211 is folded back or located behind the air handling unit—these are therefore not visible in FIG. 10A. The floor or side wall 212 may either slide out from underneath the air handling unit or be folded out. The driver for the displacement of the floor or side wall may be electronic or pneumatic with a ram or other pressure applying actuators. The sidewalls may also be mechanically secured to the air handling unit for displacement between a first position as shown in FIG. 10A and a second position where the unit comprises an air handling unit to one side of a vehicle enclosure. Junction members may be provided to secure the side walls together. Optionally, a roller blind or other closure mechanism may be envisaged to close the vehicle enclosure in its forward most face. Furthermore, whilst the side walls are presented as having a single leaf these may incorporate a number of leaves which are stacked onto one another for transportation and then readily deployed to form the vehicle enclosure. The sidewalls are preferably rigid sidewalls and are sufficient in width to isolate the contents of the enclosure. The sidewalls are preferably load bearing whereby the entire structure once assembled may be lifted up for displacement in the vicinity of its initial deployment or onto a transporter for transportation to a further location.

[0060] FIG. 11 show a further deployable enclosure where during transportation a first vehicle enclosure 213 is equipped with a number of sidewalls, a floor and a roof onto which one or two leaves of an extended structure may be carried during transportation. For example, roof leaf 214 may rest during transportation on a roof portion 215, whereby the roof leaf may be displaced as shown by arrow 216.

[0061] A central vehicle enclosure 217 may be formed as the result of the deployment of roof leaf 214 provided a second additional vehicle enclosure 218 is positioned at a sufficient distance from the first vehicle enclosure 213 in order to accommodate the central vehicle enclosure 217.

[0062] In other embodiments, one or both of the cooperating vehicle enclosures may primarily be an air handling unit whilst the central vehicle enclosure is the primary vehicle receiving portion of the assembled structure.

[0063] In further embodiments, one of the cooperating vehicle enclosures may be provided with the entirety of the leaves which together form the roof of the central vehicle enclosure. These may be stacked during transportation and then deployed as appropriate. The deployment may either require external displacement means such as a crane or other lifting contraption or be facilitated by integral actuators such as hydraulic rams or motors.

[0064] Additional junction members may be provided for securing the leaves of the roof together. In certain embodiments, there may be no floor in the central enclosure whilst in other embodiments a floor may also be formed by one or more leaves of the vehicle enclosures. The floor may for example be formed by the combination of two leaves from each one of the side enclosures.

[0065] FIG. 12 shows a further embodiment of an air handling unit generally referenced 219 from which a succession of 5 leaves is deployed such as leaves 220, 221, 222, 223 and 224. These leaves may be formed as a stack on either or both of the roof 225 or the side wall 226. Junction members may be provided to fix the angles between neighbouring leaves. Junction members may incorporate hinges to provide sufficient flexibility between adjacent leaves. Roller blinds or shutters may be provided on either or both of the front or rear faces of the structure. In this embodiment, the vehicle enclosure is twice as high as the air handling unit from which it is formed. This allows the air handling block to be transported in a particularly compact configuration and deployed into a configuration to accommodate vehicles which are considerably larger than might be expected relative to the size of the air handling unit.

[0066] The embodiment of FIG. 13 shows a further configuration where during transportation the mono-block comprising a vehicle enclosure and an air handling unit is much more compact than the prior art versions. The mono-block generally referenced 227 is formed of a first portion 228 which contains an air handling unit or block and a second portion 229 which is largely empty and may be suitable for receiving a vehicle or a vehicle part. The block 228 is however displaceable relative to the vehicle enclosure as illustrated in FIG. 13B, whereby the air handling unit may be partially located above a vehicle containing portion. The air handling unit may be lifted up through pneumatic rams such as ram 230, a motor or may simply be secured to the frame of the enclosure in an elevated position; whereby the portion 231 beneath the air handling block is provided to allow a vehicle or part of a vehicle to be housed therein.

[0067] It also allows the extraction of air to be in the roof of the enclosure whilst still allowing for a particularly compact structure during transportation.

[0068] FIG. 14 shows a tube-like vehicle enclosure 232 with two side walls, a roof and a floor portion. Located within (or partly with as shown) the walls of the vehicle enclosure, there is provided an air handling unit 233 which is displaceable with the tube-like vehicle enclosure; whereby for transportation the overall size of the module is considerably reduce and on arrival it is suitable for displacement within the tube in order to extend its dimensions and thereafter readily accept vehicles in the housing formed between the portion vacated by the air handling unit and the rest of the vehicle enclosure. Rails or other conveying means may be provided between the tube-like vehicle enclosure and the air handling unit. The displacement of the air handling unit may be through actuation or through the application of a force by external means of known kind.
