CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of and priority from UK Patent Application No. 2501994.4, filed February 11, 2025 in the UK Intellectual Property Office. The United Kingdom application is incorporated herein by reference, in its entirety.FIELD

[0002] The present invention relates to storage systems, particularly to inflatable, environmentally controlled storage enclosures for outdoor use.BACKGROUND

[0003] Outdoor storage solutions often face challenges related to environmental control, portability, and scalability. Traditional storage structures may struggle to maintain consistent internal conditions, particularly in varying weather. Inflatable structures, while portable, often lack robust environmental control. It is therefore desired to provide improvements relating to portable, environmentally controlled storage systems.

[0004] It is also desired to provide a system that can be modified and scaled up and down dependant on the amount and nature of storage required.SUMMARY

[0005] According to the present invention, there is provided an inflatable storage system comprising: an inflatable support structure; an outer cover disposed over the inflatable support structure; a main chamber for storage; at least one antechamber; a ventilation system that pumps air to the antechamber from the external environment, and pumps air from the antechamber to the main chamber; and a humidity control system.

[0006] The ventilation system may comprise a first ventilator blowing air from the ambient into the antechamber; and a second ventilator mounted between the antechamber and the main chamber to pump air from the antechamber to the main chamber. A benefit of this is improved pressure control and reduced condensation risk. Lower power fans can be used for each step of the two stage pressure increase.

[0007] The ventilators can each be provided with air purification filters and / or dehumidifiers thus providing a dual stage air cleansing process on air that enters.

[0008] In embodiments, the system may further comprise a modular connection system for expandability. This allows for scalable storage solutions adaptable to changing needs. The modular connection system may comprise inter-engageable sealing elements that link when separate units are brough together. Those inter-engageable sealing elements may be on the ends of the support structures and / or the end edges of the outer covers / floors.

[0009] The system may be provided with tethering means to allow it to be anchored in place. Linking means may be provided to interconnect adjacent units in a modular system.

[0010] In embodiments, the system may include a power supply system compatible with mains electricity, portable generators, and solar panels. This versatility enables deployment in various locations and conditions.

[0011] In embodiments the system may include insulated inner panels. Those panels may be connected to the inflatable support structure. The panels may be shaped to fill or cover openings between inflatable members of the support structure. The insulated inner panels may comprise foam sandwiched between aluminium foil layers. The insulated inner panels may include flap valves or other means to allow internal air pressure to pass through and lift the outer cover. The air would pass to a space between the outer cover and the panels / support structure. That space is fluidly part of the main chamber, however air does not tend to flow back to the main chamber.

[0012] The humidity control system may comprise one or more dehumidifier. That dehumidifier may be selected from the group consisting of condensing air driers and desiccant-type driers. Multiple dehumidifiers may be provided. Access holes maybe provided to allow drains from the or each dehumidifier to the external environment.

[0013] At least one airlock may be provided to allow personal and / or vehicle access to the main chamber. This may be through the antechamber or though a set of double doors accessing the main chamber direct. Such access airlocks are conveniently located on the ends of the structure.

[0014] The main chamber may be closed at the bottom by the surface on which the system sits. However preferably the inflatable storage system further comprising a floor. That floor may comprise a sealed base covered with a serviceable outer layer. The floor may be sealed to those other parts of the system as required to make the chambers airtight and / or watertight.

[0015] The outer cover may made of a waterproof / weather proof material. That will be suitable to shed water, especially when the outer cover is lifted by internal air pressure. Other parts exposed to the external environment may be formed of similar materials.

[0016] The inflatable support structure may comprise a framework of interconnected vertical and horizontal inflatable tubes. Those are ideally linked both physically and fluidly to form a small number (ideally one) of individual spaces to simultaneously inflate. The system creates a structure that may have many different overall shapes. A half cylinder shape is desirable. In such a conformation the support structure may be shaped as a half pipe with the outer cover supported over the curved circumferential face, and the semi-circular ends covered by end walls. Those end walls may be part of the outer cover, connected to the outer cover, or separate from the outer cover. For example, the edges of the end walls and the end edges of the outer cover may both be connected to the end of the support structure.

[0017] A roof structure designed to support solar panels may be provided. This would provide a power supply to electrical components such as the ventilation and humidity control system. Systems of the present invention may also be connected to an external power supply such as the mains or a generator. Solar panels may be provided by mounting solar panels, ideally light weight ones, to a separate outer sheet that that can be placed over the outer cover.

[0018] The antechamber comprises an intermediate space between the external environment and the main chamber. That may be between outer and inner end walls / covers. Those may be at one or both ends of the structure.

[0019] The ventilation system may be is configured to maintain super atmospheric pressure within a main chamber of the system. This not only shapes the outer cover to better shed precipitation, but also ensure air flows outwards thus preventing ingress of external air save through the ventilation system. The ventilation system may include filters or other ways to pre-treat air entering the main chamber.

[0020] As will be appreciated, the present invention provides a portable, scalable storage solution with enhanced environmental control.

[0021] According to another aspect of the present invention, there is provided a method of operating an inflatable storage system, the method comprising: inflating a support structure; maintaining super atmospheric pressure within a main chamber to lift an outer cover; and controlling internal humidity using a humidity control system.

[0022] Ideally the method involves pumping air to an antechamber using a first ventilator and transferring pressurized air from the antechamber to the main chamber using a second ventilator.

[0023] As noted, the system may be modular thus the method may further comprise expanding the storage system by connecting additional modular sections.

[0024] The method may further comprise powering the storage system using one or more of mains electricity, a portable generator, and solar panels.

[0025] To maintain environmental conditions within the main chamber, the main chamber may be accessed using an airlock when inflated.BRIEF DESCRIPTION OF THE FIGURES

[0037] Referring to FIG. 1, but also the other figures generally, an inflatable storage system 10 is shown. The system 10 comprises an inflatable support structure including vertical supports 12 and horizontal supports 14. These supports 12, 14 may be inflated together to form a rigid framework for the system 10. An outer cover 20 is disposed over the inflatable support structure. The outer cover 20 may be made of a durable, waterproof material designed to shed water.

[0038] Insulated panels 21 are positioned within the spaces between vertical and horizontal supports of the inflatable support structure. These panels 21 may comprise foam sandwiched between aluminium foil layers for improved thermal insulation. The system 10 includes a first outer end wall 22a and a second outer end wall 22b. Corresponding to these are a first inner end wall 24a and a second inner end wall 24b. These end walls form part of an airlock system of the storage enclosure.

[0039] An antechamber 26 is formed between the outer and inner end walls at one end of the system 10. This is normally the end opposite to a main entrance end. This antechamber 26 serves as an airlock, helping to maintain the environmental conditions within the main chamber 28. The antechamber 28 also allows for the stepwise increase in pressure. The system 10 incorporates a ventilation system comprising a first ventilator 34 and a second ventilator 36. The first ventilator 34 is mounted to inflate the antechamber 26 with air from the ambient, while the second ventilator 36 transfers air from the antechamber 26 to the main chamber 28. The arrows indicate air flow direction.

[0040] A humidity control system, represented by dehumidifier 30, is provided within the main chamber 28. This dehumidifier 30 may be any suitable air dryer such as a condensing air drier or a desiccant-type drier. A drain 32 is provided for the dehumidifier 30 to remove condensed moisture.

[0041] The system 10 may include flap valves 25 in the insulated panels 21. These flap valves 25 allow internal air pressure to get to the space between the panels and the outer cover to lift the outer cover 20 into a water-shedding shape. A floor 19 is provided. The floor may be a strong, sealed, and welded base structure covered with a serviceable outer layer.

[0042] Referring now to FIG. 2, a transverse cross-sectional view of the inflatable storage system 10 is shown. The vertical supports 12 and horizontal supports 14 form the arched structure of the system. The main chamber 28 is clearly visible, along with the second ventilator 36 positioned to pump air from the antechamber to the main chamber. An antechamber airlock 43 is shown in the end wall of the structure.

[0043] FIG. 3 illustrates an end view of the inflatable storage system 10 from a main entrance end. The second outer end wall 22b is visible, along with a large access door 40 and a small access airlock 44. The floor 19 is shown at the base of the structure. The small access airlock 44 may be used by people to gain access without deflation. Opening the large access door 40 allows larger stored items to be introduced or removed. Those might for example be vehicles that can drive in and out. Potentially such access may require reinflation of the main chamber if the airlock space between the inner and outer end walls is not large enough for such a larger stored item to transit without both being open.

[0044] In FIG. 4, a perspective view of a very similar embodiment of inflatable storage system 10. The large access door 40 is open but visible, along with the vertical supports 12. Tethering straps 42 are shown for securing the structure to the ground.

[0045] FIG. 5 provides a detailed opposite end view. This shows the antechamber with the first outer end wall 22a removed. The first ventilator 34 is shown (although the first outer end wall 22a in which it would be mounted is not) and the second ventilator 36 is also visible as part of the first inner end wall 24a. The tethering straps 42 are also shown.

[0046] FIG. 6 shows an embodiment of support structure on its own with no outer cover, panels, floor or end walls. The framework of vertical and horizontals supports is clear. That framework can be designed in various ways to suit the desired end shape and load requirements.

[0047] FIG. 7 shows the modular nature of the inflatable storage system 10. FIG. 7 shows a side view of two adjoining units. A linking connector 45 is visible between the units to seal them together and prevent escape of air from the main chamber. That linking connector 45 may comprise inter-engageable flaps on each unit that may be engaged when they are placed in close proximity. Each unit comprises an inflatable storage system 10 substantially as described herein, but with adjoining end walls omitted, or opened to link the main chambers.

[0048] Each inflatable storage system 10, be that one unit or a plurality of linked units forming a larger system, may have one antechamber, or multiple antechambers. Multiple antechambers may be fluidly linked or may be discrete. The ventilation system may comprise more than one first ventilator and / or more than one second ventilator.

[0049] FIGS. 8 and 9 provide external views of an inflatable storage system 10 comprising 2 joined units. FIG. 8 shows a perspective end view with the linking connector 45 and antechamber airlock 43 visible. FIG. 9 is an end view, clearly showing the small access airlock 44 next to the large access door 40.

[0050] Finally, FIG. 10 offers an interior view of the inflatable storage system 10. The vertical supports 12 and horizontal supports 14 are visible, along with the small access airlock 44 and linking connector 45. Connection straps 48 are shown linking adjacent support structures, and a floor join seal 50 is visible at the base of the structure to provide a join between adjacent floors 19. This is ideally a waterproof seal. A floor seal cover may be provided to protect the seal as storage items are driven or rolled over the join.

[0051] Parts that need to be selectively sealed together may use standard releasable sealing techniques to interconnect. This may involve two-part hook and loop fasteners and zip fasteners.

[0052] In operation, the inflatable support structure is inflated, forming a rigid framework. The outer cover 20 is arranged over the support structure and inner outer end walls are provided on the ends. That may be before or after the support structure is inflated. A floor 19 is provided. The outer cover, end walls and floor are suitably inter-connected or connected to the support structure to provide a sealed main chamber and antechamber. The first ventilator 34 inflates the antechamber 26, increasing the pressure within. The second ventilator 36 then transfers this pressurized air into the main chamber 28, further increasing the internal pressure.

[0053] Generally, once the system is assembled but the main chamber is not inflated, storage items (such as vehicles) are arranged inside. The doors are closed and then the antechamber and main chamber are inflated. It is possible to provide a high-volume inflation port. This allows a high-volume blower to be used to assist in initial inflation. That port can be closed when the main chamber is sufficiently inflated. The ventilation system can then take over.

[0054] The super atmospheric pressure within the main chamber 28 lifts the outer cover 20 into a shape designed to shed heavy rainfall and prevent water pockets from forming along the roof. The valves 25 in the insulated panels 21 facilitate this process by ensuring air can access the space between the insulated panels and the outer cover.

[0055] The dehumidifier 30 controls the humidity within the main chamber 28, removing excess moisture which is then expelled via the drain 32. The system 10 may be powered by mains electricity, portable generators, or solar panels. Solar panels may be mounted on the roof structure. The system may be provided with sealable ports to allow cables and other services to enter or exit the main chamber and antechamber as required.

[0056] For expandability, the system 10 includes a modular connection system allowing additional sections to be added. This involves airtight and waterproof seals between sections, as shown by the linking connector 45 and connection straps 48.

[0057] Access to the storage area is provided through the large access door 40 and small access airlock 44. The airlocks, preventing loss of too much air or uncontrolled entry of dust.

[0058] The structure may be insulated to help maintain temperature stability, protecting the enclosure from both high temperatures during the day and helping maintain internal temperature overnight.

[0059] Some or all of the parts, especially those attached to the support structure are individually serviceable and replaceable. This includes the outer cover, end walls, any doors or access panels, floors and any seals. These are designed to be easily replaced, so that the structure may be serviced and repaired to ensure a longer life for these outdoor units.

[0060] It is possible for the storage system to have a control / telemetry system. Such a system can monitor and / or record a range of things for example: ambient humidity / temperature, internal storage humidity / temperature, internal air pressure, performance of integrated power systems such as solar panels and storage batteries, and the function of storage equipment (such as vehicle battery charge) etc. Monitoring the internal air pressure will show any damage causing leakage and will also record any access as the internal air pressure momently drops on entry. The telemetry system may also include internal and / or external cameras. All this information can be accessed remotely.

[0061] A control / telemetry system can also allow automatic or manual control of the internal dehumidifier(s) and ventilators. Controlling the ventilator fans will not only allow control of pressure, but also will allow a level of control over internal temperatures. The system may have the ability to reverse the airflow in the event of the internal temperatures overheating (i.e. exceeding ambient temperatures during the hottest part of the day) or overpressure.

[0037] Referring to FIG. 1, but also the other figures generally, an inflatable storage system 10 is shown. The system 10 comprises an inflatable support structure including vertical supports 12 and horizontal supports 14. These supports 12, 14 may be inflated together to form a rigid framework for the system 10. An outer cover 20 is disposed over the inflatable support structure. The outer cover 20 may be made of a durable, waterproof material designed to shed water.

[0038] Insulated panels 21 are positioned within the spaces between vertical and horizontal supports of the inflatable support structure. These panels 21 may comprise foam sandwiched between aluminium foil layers for improved thermal insulation. The system 10 includes a first outer end wall 22a and a second outer end wall 22b. Corresponding to these are a first inner end wall 24a and a second inner end wall 24b. These end walls form part of an airlock system of the storage enclosure.

[0039] An antechamber 26 is formed between the outer and inner end walls at one end of the system 10. This is normally the end opposite to a main entrance end. This antechamber 26 serves as an airlock, helping to maintain the environmental conditions within the main chamber 28. The antechamber 28 also allows for the stepwise increase in pressure. The system 10 incorporates a ventilation system comprising a first ventilator 34 and a second ventilator 36. The first ventilator 34 is mounted to inflate the antechamber 26 with air from the ambient, while the second ventilator 36 transfers air from the antechamber 26 to the main chamber 28. The arrows indicate air flow direction.

[0040] A humidity control system, represented by dehumidifier 30, is provided within the main chamber 28. This dehumidifier 30 may be any suitable air dryer such as a condensing air drier or a desiccant-type drier. A drain 32 is provided for the dehumidifier 30 to remove condensed moisture.

[0041] The system 10 may include flap valves 25 in the insulated panels 21. These flap valves 25 allow internal air pressure to get to the space between the panels and the outer cover to lift the outer cover 20 into a water-shedding shape. A floor 19 is provided. The floor may be a strong, sealed, and welded base structure covered with a serviceable outer layer.

[0042] Referring now to FIG. 2, a transverse cross-sectional view of the inflatable storage system 10 is shown. The vertical supports 12 and horizontal supports 14 form the arched structure of the system. The main chamber 28 is clearly visible, along with the second ventilator 36 positioned to pump air from the antechamber to the main chamber. An antechamber airlock 43 is shown in the end wall of the structure.

[0043] FIG. 3 illustrates an end view of the inflatable storage system 10 from a main entrance end. The second outer end wall 22b is visible, along with a large access door 40 and a small access airlock 44. The floor 19 is shown at the base of the structure. The small access airlock 44 may be used by people to gain access without deflation. Opening the large access door 40 allows larger stored items to be introduced or removed. Those might for example be vehicles that can drive in and out. Potentially such access may require reinflation of the main chamber if the airlock space between the inner and outer end walls is not large enough for such a larger stored item to transit without both being open.

[0044] In FIG. 4, a perspective view of a very similar embodiment of inflatable storage system 10. The large access door 40 is open but visible, along with the vertical supports 12. Tethering straps 42 are shown for securing the structure to the ground.

[0045] FIG. 5 provides a detailed opposite end view. This shows the antechamber with the first outer end wall 22a removed. The first ventilator 34 is shown (although the first outer end wall 22a in which it would be mounted is not) and the second ventilator 36 is also visible as part of the first inner end wall 24a. The tethering straps 42 are also shown.

[0046] FIG. 6 shows an embodiment of support structure on its own with no outer cover, panels, floor or end walls. The framework of vertical and horizontals supports is clear. That framework can be designed in various ways to suit the desired end shape and load requirements.

[0047] FIG. 7 shows the modular nature of the inflatable storage system 10. FIG. 7 shows a side view of two adjoining units. A linking connector 45 is visible between the units to seal them together and prevent escape of air from the main chamber. That linking connector 45 may comprise inter-engageable flaps on each unit that may be engaged when they are placed in close proximity. Each unit comprises an inflatable storage system 10 substantially as described herein, but with adjoining end walls omitted, or opened to link the main chambers.

[0048] Each inflatable storage system 10, be that one unit or a plurality of linked units forming a larger system, may have one antechamber, or multiple antechambers. Multiple antechambers may be fluidly linked or may be discrete. The ventilation system may comprise more than one first ventilator and / or more than one second ventilator.

[0049] FIGS. 8 and 9 provide external views of an inflatable storage system 10 comprising 2 joined units. FIG. 8 shows a perspective end view with the linking connector 45 and antechamber airlock 43 visible. FIG. 9 is an end view, clearly showing the small access airlock 44 next to the large access door 40.

[0050] Finally, FIG. 10 offers an interior view of the inflatable storage system 10. The vertical supports 12 and horizontal supports 14 are visible, along with the small access airlock 44 and linking connector 45. Connection straps 48 are shown linking adjacent support structures, and a floor join seal 50 is visible at the base of the structure to provide a join between adjacent floors 19. This is ideally a waterproof seal. A floor seal cover may be provided to protect the seal as storage items are driven or rolled over the join.

[0051] Parts that need to be selectively sealed together may use standard releasable sealing techniques to interconnect. This may involve two-part hook and loop fasteners and zip fasteners.

[0052] In operation, the inflatable support structure is inflated, forming a rigid framework. The outer cover 20 is arranged over the support structure and inner outer end walls are provided on the ends. That may be before or after the support structure is inflated. A floor 19 is provided. The outer cover, end walls and floor are suitably inter-connected or connected to the support structure to provide a sealed main chamber and antechamber. The first ventilator 34 inflates the antechamber 26, increasing the pressure within. The second ventilator 36 then transfers this pressurized air into the main chamber 28, further increasing the internal pressure.

[0053] Generally, once the system is assembled but the main chamber is not inflated, storage items (such as vehicles) are arranged inside. The doors are closed and then the antechamber and main chamber are inflated. It is possible to provide a high-volume inflation port. This allows a high-volume blower to be used to assist in initial inflation. That port can be closed when the main chamber is sufficiently inflated. The ventilation system can then take over.

[0054] The super atmospheric pressure within the main chamber 28 lifts the outer cover 20 into a shape designed to shed heavy rainfall and prevent water pockets from forming along the roof. The valves 25 in the insulated panels 21 facilitate this process by ensuring air can access the space between the insulated panels and the outer cover.

[0055] The dehumidifier 30 controls the humidity within the main chamber 28, removing excess moisture which is then expelled via the drain 32. The system 10 may be powered by mains electricity, portable generators, or solar panels. Solar panels may be mounted on the roof structure. The system may be provided with sealable ports to allow cables and other services to enter or exit the main chamber and antechamber as required.

[0056] For expandability, the system 10 includes a modular connection system allowing additional sections to be added. This involves airtight and waterproof seals between sections, as shown by the linking connector 45 and connection straps 48.

[0057] Access to the storage area is provided through the large access door 40 and small access airlock 44. The airlocks, preventing loss of too much air or uncontrolled entry of dust.

[0058] The structure may be insulated to help maintain temperature stability, protecting the enclosure from both high temperatures during the day and helping maintain internal temperature overnight.

[0059] Some or all of the parts, especially those attached to the support structure are individually serviceable and replaceable. This includes the outer cover, end walls, any doors or access panels, floors and any seals. These are designed to be easily replaced, so that the structure may be serviced and repaired to ensure a longer life for these outdoor units.

[0060] It is possible for the storage system to have a control / telemetry system. Such a system can monitor and / or record a range of things for example: ambient humidity / temperature, internal storage humidity / temperature, internal air pressure, performance of integrated power systems such as solar panels and storage batteries, and the function of storage equipment (such as vehicle battery charge) etc. Monitoring the internal air pressure will show any damage causing leakage and will also record any access as the internal air pressure momently drops on entry. The telemetry system may also include internal and / or external cameras. All this information can be accessed remotely.

[0061] A control / telemetry system can also allow automatic or manual control of the internal dehumidifier(s) and ventilators. Controlling the ventilator fans will not only allow control of pressure, but also will allow a level of control over internal temperatures. The system may have the ability to reverse the airflow in the event of the internal temperatures overheating (i.e. exceeding ambient temperatures during the hottest part of the day) or overpressure.
