BACKGROUND OF THE INVENTION
Diving with Self-Contained Underwater Breathing Apparatus (SCUBA) is an activity that currently encompasses such areas like recreation/tourism, industrial/commercial, security/rescue and scientific research. It stands for an activity that features a significant number of equipment which, due to its nature (weight, size, and fragility) entails an outstanding logistic operation. As for recreational dives, dive centres represent a chief support for scuba diving, by providing the facilities whereupon diver may find availability of rental equipment, as well as a place to store, to remove and to wash his/her own scuba gear, charging one's scuba tanks, while getting transportation to the dive spot, dive training centre, among other services.
The equipment transportation, distribution and control, as well as washing, drying-out and storage of scuba gear stand for a major time and labour employed in the activity of a recreational dive centre, particularly if its location is away from dive spots or the mooring point. Scuba gear comprises both heavy equipment and fragile items, and its poor storage and transportation, even if along small distances, can frequently lead to serious damages to the equipment.
Whenever so possible, recreational divers are always searching for new dive spots. However, many areas provide optimum conditions for diving during only part of the year, which in turn will restrict the launch of new dive centres in those areas that fail to be properly explored by diving tourism industry due to its lack of available logistic support.
As far as scientific diving, commercial/industrial diving or diving carried out by security and rescue forces, the mobile scuba diving centre can further meet, also due to its specific layout, to straightforward requirements of easier displacement means, improved safety in transportation, enhanced facility, comfort and swiftness to dress/undress diver's own scuba gear and the proper storage, maintenance and preservation of all scuba gears.
GENERAL DESCRIPTION OF THE INVENTION
The mobile scuba diving centre is a complete mobile, fixed dive centre with air lines for filling scuba tanks and water lines to wash the integrated equipment, hereby described as non-limiting as a module applied over a motor vehicle-based trailer.
The mobile scuba diving centre comprises a main bench wherein scuba tanks are fitted into, secured with clamps to the bench backside or inside boxes that are embedded into the structure. Buoyancy Compensator Jackets [BCs] may be placed onto the scuba tanks and, therefore, can be safely carried. Under scuba tanks, individual drawers can carry various items of the remaining scuba diver's gear, placed directly underneath the scuba tank that he/she will use.
Both drawers and the bench are faced outwardly, so to make more efficient the space use and so to ensure that more than a scuba diver may easily gear up at the same time. The bench overall size and the ways of securing scuba tanks are designed in order to lessen the effort placed upon the inspection, adjustment and dressing tasks of the entire scuba gear. On the side of this main structure, the invention discloses two steps or retractable ramps that, as they are open, will make the access to the bench and drawers easier, further enabling a dressing base whereupon scuba divers may dress or undress one's scuba gear without dirtying it or damaging it.
Above this base structure, a sealed coverage is applied to, which can be equipped with lighting means. The coverage side doors open outwardly, thus comprising an awning providing protection against rain/sun light in the scuba divers dressing area.
A rotary hanging rod fixed onto the base provides the proper support for wetsuits and dry-suits hung onto hangers. When it is unfolded, it makes the wetsuits and dry-suits available on the coverage outside, and it can be folded to close the coverage for transportation purposes. The compressor lines for scuba tanks filling runs underneath the bench, in the rear of scuba tanks. Adapters to interconnect the compressor hoses to scuba tanks are arranged into compartments that are embedded onto the structure, so to become readily available upon the scuba tanks charging, yet protected and out of the way through the remaining operations. Above the drawers inside the bench structure and running along the coverage structure ceiling, water and spray line assemblies run and, as the coverage is closed, it enables the automatic rinsing of the entire equipment, including concurrently with the scuba tanking filling process. All drawers can be removed from the structure, thus allowing access to its inside for washing and maintenance purposes.
The invention further comprises a dry area to store a portable scuba dive compressor along with a water tank for washing, plus additional equipment, a storeroom and further items. The same arrangement and structure can be otherwise applied to a fixed container, a motor vehicle or alike, whereby the entire arrangement and storage of the equipment has been designed aiming its safe transportation immediately after it has been used.

DETAILED DESCRIPTION OF THE INVENTION
The mobile scuba diving centre is a complete mobile, fixed dive centre with air lines for filling scuba tanks and water lines to wash the integrated equipment, hereby described as non-limiting as a module applied over a motor vehicle-based trailer.
The version that includes a trailer and depicted in the assembly of drawings enclosed hereto, describes the mobile scuba diving centre carrying scuba gear for twelve divers.
As far as the trailer is concerned, the mobile scuba diving centre is concentrated in a trailer assembled onto a typical chassis, with a base module and bodywork made of fibreglass with steelwork. The base module comprises a shell (1) that is fibreglass moulded. The shell (1) comprises stowage drawers (3) for the scuba divers equipment, ramp/access steps (13), scuba tank clipping devices (4) or boxes (5) to support scuba tanks (15), the compressor's hose lines for filling scuba tanks (6), adapters for the scuba tank filling station (7), a rotary hanging rod to hang wetsuits and dry-suits (8), the hose, spray lines to wash the equipment inside the drawers (9).
The hoses, spray line assembly to wash BCs, scuba tanks and wetsuits (10) is secured to the interior ceiling of the bodywork structure (12), which includes a stowage area (11). Structure and the bodywork are designed so to, as they are closed, ensure the equipment safety inside, either when the vehicle is parked or is travelling.
DETAILED OPERATION OF THE MOBILE SCUBA DIVING CENTRE
The operation of the mobile scuba diving centre starts with the opening of the bodywork, thus changing the trailer into a fully operational scuba diving centre, as the ramp/access steps (13) are lowered, followed with unfolding the protection awnings (14) and unfolding the hanging rods (8) whereupon wetsuits and dry-suits are to be arranged, in hangers.
The remaining equipment related to each diver, namely, weight belt, fins, mask, regulator and further accessories are properly stored within individual drawers (3) directly under the scuba tank (15) that shall be used by the diver. The Buoyancy Compensator Jackets [BCs] are carried already geared up onto scuba tanks (15).
Upon completion of diving operation, each diver shall return the scuba gear, which shall be promptly and correctly arranged to be washed, for recharging of scuba tanks (15) and for its transportation. Scuba tanks (15) are to be recharged, by using the adapters (7) of the compressor's hose lines to fill scuba tanks (6) incorporated within the structure and, as the awnings and the ramp/steps are folded, the spraying system can be activated to wash the entire scuba gear (9, 10).
The mobile scuba diving centre allocates an area for the assembly of a tap water tank and the relevant water pump for the equipment washing (17) and a compressor to fill the scuba tanks (18). Such compressor can be of a portable type. Filling and washing stations can also be fed via an external compressor line and water supply network, whereby its connection is directly made outside the structure (16). Once it has been washed, the equipment is properly stored to be dried and to be conveyed, as it becomes ready to be used again.
The following Claims further emphasise the preferred embodiments of this invention.
