FIELD OF INVENTION:

[0001] The invention relates to an underwater helmet. More particularly the invention relates to the construction of the underwater walking helmet to explore shallow underwater world that is filled with marine life and corals.

BACKGROUND:

[0002] Most of the conventional underwater walking helmets that are being used today include plurality of weights that are attached permanently within the helmet. As the user experiences the unexpected scenario underwater, he/she will not be able to dismantle weights underwater and becomes difficult for the user to come up to the surface.

[0003] The conventional underwater walking helmet includes the fixed amount of weights and it becomes difficult for the user to add or remove weights from the helmet based on his/her weight to create required negative buoyancy and also results in an unbalanced state for the user to walk underwater. The conventional helmet makes use of number of gears like for scuba diving apparatus and makes difficult for a non-swimmer to go underwater.

[0004] The fastening of the helmet to the user makes use of the traditional buckles that requires more time for the user to fasten or loosen the helmet in an emergency scenario. The connection between the conventional underwater walking helmet and the user is provided using the belts that are made up of degradable material, when these belts are wet, they stretch and become loose. Upon returning to the surface, they dry and crack.

[0005] Hence to overcome all the above mentioned difficulties, there exists a need for an underwater walking helmet for one or more users, that is cost effective, efficient and user friendly. SUMMARY:

[0017] Unless otherwise defined, all technical and scientific terms used herein have the meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The systems, methods, and examples provided herein are only illustrative and not intended to be limiting.

[0018] Embodiments of the present invention will be described below in detail with reference to the accompanying figures.

[0019] Figure la and lb illustrates an overall front and side view of an inventive underwater walking helmet 100. The underwater walking helmet 100 includes a quick release valve 1, a non-return valve 2, an acrylic viewing glass 3, a fibre reinforced plastic material 4, a track sliding means 5, front side plurality of straps 6, back side plurality of straps 7, a quick release clasp 8, and a plurality of external weights 9.

[0020] Further, in accordance with the present invention, the quick release valve 1 may include an air supplying hose with coupling and a receptacle means to hold the air supplying hose with coupling and together works on the principle of choke valve mechanism with single side choke valve. The receptacle means may be considered as female part for holding the hose to the helmet. The non-return valve 2 may be fabricated with the helmet, and an air supplying hose with coupling is attached to the valve 2 for only passing air inside the helmet 100 from the surface. The fibre reinforced plastic material can be any composite material, made of a polymer matrix reinforced with fibres.

[0021] Further, in accordance with the present invention, the track sliding means 5 may be used to slide the plurality of weights based on the user's interest. The plurality of straps 6 and 7 may be made of any flexible material and used to fasten, secure, or carry slidable weights on the each shoulder of the user. The quick release clasp 8 may be a device with the single click fastener like buckle or the like and may interlock the plurality of straps together firmly.

[0022] Further, the plurality of weights 9 are fabricated in a box attached to fibre reinforced plastic material and distributed equally over each shoulder of the user through the track sliding means. The pluralities of weights are slidable and can be added or removed easily by the user underwater. The plurality of weights may be used to provide required negative buoyancy of the user and allow the user to walk underwater in a balanced state. However the user may even slide and adjust the weights underwater through the use of track sliding means. The plurality of external weights 9 may be made up of spherical and smooth metal balls like ball bearing or lead weights or the like.

[0023] Figure 2 illustrates a system 200 for supplying air to the underwater walking helmet 100. The system 200 includes the underwater walking helmet 100 on the user, the air supplying hose 22, an air control panel 23, one or more air tanks 24 and one or more compressors 25. The air supplying hose may be made up of non-degradable material that may resist the underwater condition. The air supplying hose also includes a coupling, which may be used to attach to the underwater walking helmet 100. The air control panel 23 may include the control system for controlling the amount of breathing gas that is supplied to the underwater walking helmet. The compressors 25 may be any kind of high pressure compressors that can be worked by electric motor, diesel engine, gasoline engine or any other alternative.

[0024] In one exemplary embodiment the present invention, the underwater walking helmet includes the quick release valve with a non-return valve, such that the air can only be supplied from the surface to the helmet in one way direction. At the emergency scenario, when the user is at the risk, the air may already be filled up in the helmet and give enough time for the user to come to the surface without risking his life.

[0025] In another embodiment of the present invention, the shape of the underwater walking helmet may have a bulge at the front side of the helmet, to allow the user to insert his/her hand to equalize pressure points based on his/her needs.

[0026] In another embodiment of the present invention, the acrylic viewing glass 3 may be made up of acrylic material or Poly (methyl methacrylate) material and may also be referred to as plexiglas, acrylite, lucite, perspex and others. The glass 3 may include viewing glass of various thicknesses like in the range between 8mm to 10mm or the like. The glass 3 may also be resistant enough to undertake pressure underwater and may give a clear view to the user.

[0027] In another embodiment of the present invention, the compressor may pump the high pressure air and the high pressure air may than be transported to the storage tank and from the storage tank the high pressure air may be passed through the air control panel and then delivered to the user through the quick release valve attached to the underwater walking helmet.

[0028] In another embodiment of the present invention, the underwater walking helmet may also include a safety locking system, like for example when a user wearing the helmet underwater bend towards the front and loose the balance and is in urgent need to ditch the helmet, So quick release clasp may help the user to ditch the helmet as soon as possible and save his/her life.

[0029] As is evident from the above disclosure, the system and methods of the present invention are thus advantageous in providing efficient and economical underwater walking helmet that is; without any gears, with slidable weights, with improved safety using quick release valve, with the ability to provide required negative buoyancy for each user and make the user walk comfortably underwater, with firm fitting between the helmet and the user by making use of straps.
