Description

[0001] Snorkel Telescopic Collar

[0002] Field of invention

[0003]

[0001] The present utility model belongs to the diving equipment sector and refers to a device that allows breathing during surface diving known as a snorkel - a word incorporated from the English language corresponding to snorkel.

[0004] State of the art

[0005]

[0002] Current underwater breathing equipment known as a snorkel basically works with a breathing tube 35 to 45 cm long that is connected to a mouthpiece and has an opening on the opposite side, located above the user's head, sufficient to reach the air above the water's surface. For proper use, it needs to be attached to the goggle straps. Another option to achieve the same goal is the snorkel mask, which consists of a mask that hermetically covers the user's entire face, including eyes, nose, and mouth, connected to a small tube at the top, just above the head, to reach the surface air. This mask must be secured by an elastic strap at the back of the head.To use these devices, the user must position themselves with their back facing upwards and keep their face submerged, allowing them to look at the bottom of the water while breathing, without having to lift their head, and thus remain observing the underwater images for as long as they wish.

[0003] Such equipment is used for diving for recreational purposes, fishing, swimming training, etc. In addition to simple models consisting of a duct connected to a mouthpiece, the equipment may contain purge valves, which serve to expel water, as well as check valves installed in the part of the duct above the water surface, in order to prevent flooding of the equipment.

[0006]

[0004] To illustrate the state of the art closest to the utility model, we highlight document US5697362 - "Swimming device", which discloses a device that improves the practice of surface swimming and snorkeling by eliminating the need to turn the head to breathe, reducing physical effort and hydrostatic drag.

[0007] Functional improvement

[0008]

[0005] The two equipment models currently used, the traditional snorkel and the snorkel mask, have distinct characteristics and offer advantages and disadvantages when compared, but the model presented in this descriptive report surpasses them in practicality and versatility. Unlike existing models, the telescopic collar snorkel was designed to be worn around the neck like a collar, comfortably and independently of the diving mask, which makes its portability absolutely advantageous, as the user can carry it as an integral part of their own body and be prepared for diving at any time. Furthermore, to enhance its portability, the equipment has a telescopic breathing tube designed to be retracted into a small compartment behind the user's neck and activated to be extended above the water's surface with just a breath through the breathing mouthpiece.

[0009]

[0006] Continuing the comparison regarding practicality and versatility, it is observed that the traditional snorkel is a piece completely dependent on its connection to the mask that covers the eyes; that is, for the user to use it, it must be connected to the mask's fastening elastic. The snorkel mask, in turn, is even less practical because of its size, since when not in use it becomes an object completely disconnected from the user's body. In contrast, the telescopic collar snorkel can be used without a diving mask, with a diving mask, or even with simple swimming goggles, and is always comfortably positioned around the neck, even when the user is out of the water.

[0010]

[0007] And standing out from document US5697362, for example, a snorkel with corrugated hose connections on the upper section allows for easy placement of the equipment around the neck, avoiding the need to put it on over the user's head, which could cause entanglement with diving or swimming goggles or even get caught in the bather's hair. Due to the use of these connections and the elasticity of the corrugated hoses, the telescopic collar snorkel does not require any adjustment to adapt to the user's body, as it will be manufactured in only three sizes: small, medium, and large. Adjustment could cause considerable inconvenience to the user due to the need to repeat the procedure with each new use, in addition to causing wear and tear due to stress and friction on any mechanism used for this purpose.The connections also act as a safety mechanism, preventing the bather from being strangled if someone or something gets caught in the equipment while it is around the neck, since they do not have a locking mechanism and are configured for removal that does not require force, disconnecting easily.

[0011]

[0008] When the telescopic neck hood is placed around the neck, but is not yet in use for underwater breathing, the telescopic tube remains retracted and protected in a compartment in the upper section, only 4 cm deep, positioned behind the swimmer's neck. This allows for its portability in any environment outside of water without major problems. The tube can be activated before or after the swimmer enters the water, as it is done by blowing through the mouthpiece, without the need to use the hands to pull and open the telescopic tube, allowing them to remain free to assist in flotation on the water.

[0012]

[0009] The telescopic tube, when closed by the cap, prevents water from entering the equipment before use, thus preventing the bather from having to purge the water before taking their first breaths.

[0013]

[0010] Corrugated hoses are more resistant to kinks that can cause airflow obstruction in the equipment. In addition, they are more flexible and elastic, ensuring a proper and comfortable fit without the need for adjustments. Brief description of the drawings.

[0021] Description of the utility model

[0022]

[0018] Unlike existing snorkels, the telescopic collar snorkel has, instead of just one rigid duct, two corrugated hoses (4) that have been designed to contour the user’s neck like a collar (11) and serve as conduits for the air needed for diving, in addition to a telescopic duct (6) which, in its retracted position, is housed in the section we call the upper section (5) and must be extended to reach the surface air.

[0023]

[0019] The nozzle (2) connects to a part we call the lower section (1) which has, at the opposite end, the flooding reservoir (3a) that has the function of preventing a small volume of water inside the equipment from forcing the user to perform the de-flooding maneuver using the purge valve (3b). Thus, the passage of outside air to the nozzle will only be hindered when a volume of water greater than the capacity of the flooding reservoir (3a) enters. The lower section (1) connects to the corrugated hoses (4) which, in addition to allowing air to pass through two ways, allow the user to facilitate de-flooding by compressing them with their hands and blowing through the nozzle (2) to force the water out through the purge valve (3b).

[0024]

[0020] The hoses (4) have a corrugated structure to increase elasticity, prevent kinks that could obstruct airflow and provide comfort during use of the equipment. The said corrugated hoses (4) connect to the rods (5a) of the upper section (5) which was designed to house the telescopic duct (6) and is located just behind the user's neck.

[0025]

[0021] The upper section (5) has a channel (9) for air passage, which allows the telescopic duct (6) to be activated with just a puff of air emitted through the nozzle (2), while the user uses the palm of one hand to cover the purge valve (3b). When retracted, the telescopic duct (6) fits perfectly into the upper section (5), which is closed by a cover (8) connected to the last ring of the telescopic duct (6). The last ring, which has the smallest diameter, has holes (7) on the sides of its walls for the entry of air coming from the surface.

[0026]

[0022] The telescopic duct (6) consists of several conical rings, which allows it to be extended. The rings fit together in such a way that, after being extended by the user's breath, they form an airtight structure to prevent water from entering the side of the duct and to allow free air circulation inside it.

[0027]

[0023] The rods (5a) of the upper section (5) are arched in relation to their own longitudinal axis, forming an angle with a measure between 5 o degrees and 45° degrees, that is, between TT / 36 rad and TT / 45 rad, as shown in Figure 7. The reason for this curvature is to ensure the perpendicular positioning of the telescopic tube (6) in relation to the horizontal plane of the water surface.

[0028]

[0024] The connection between the corrugated hoses (4) and the rods (5a) is made by movable connectors (5b) that allow for attachment and detachment to enable the placement of the equipment around the user's neck (11).

[0025] The lower (1) and upper (5) sections, the telescopic duct (6) and the cap (8) may be made of plastic material, variations of PVC or any alloys that are lightweight material. The mouthpiece (2), the valve (3b), and the corrugated hoses (4) must be made of more flexible material such as silicone or rubber.

[0029]

[0026] Among all the parts of the telescopic collar snorkel, only the mouthpiece (2) and the purge valve (3b) have a strict correspondence with respect to the current state of the art. All the remaining parts that make up the present utility model are marked by the inventive act.

[0030] Examples of implementations of the utility model

[0031]

[0027] The telescopic collar snorkel utility model presented in this report is constructed in such a way that the user, with one of the movable connectors (5b) open, places the equipment around the neck and then connects one of the corrugated hoses (4) to the upper section (5). It can also be done by means of pre-connected pieces so that it is placed around the neck, passing over the user's head, as if wearing the object, using the elasticity of the corrugated hoses (4). Another simpler possibility for embodying the model can use, instead of the telescopic duct (6), a bellows duct capable of increasing in size by means of manual traction.
