Definitions

  • 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.
  • 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.
  • 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.
  • Such equipment is used for diving for recreational purposes, fishing, swimming training, etc.
  • the equipment may contain purge valves, which serve to expel water, as well as check valves installed in the part of the tube above the water surface, in order to prevent flooding of the equipment.
  • the two equipment models currently used have distinct characteristics and offer advantages and disadvantages when compared, but the model presented in this descriptive report surpasses them in practicality and versatility.
  • 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.
  • 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.
  • 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.
  • 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.
  • the telescopic tube 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 operated 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.
  • 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.
  • 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
  • Figure 1 shows a view of the entire equipment with the telescopic duct (6) extended.
  • Figure 2 shows a view of the entire equipment with the telescopic duct (6) retracted.
  • Figure 3 shows a view of the lower section (1), where the purge valve (3b) and the flooding tank (3a) can be seen.
  • Figures 4 and 5 show a view of the interior of the upper section (5) where the telescopic duct (6) fits.
  • Figure 6 shows a view of the upper end of the telescopic duct (6) and its cover (8).
  • Figure 7 shows the side view of the upper section (5) with the telescopic duct (6) retracted and the cover closed (8).
  • Figure 8 shows how the telescopic collar snorkel is used around the user's neck, when the mouthpiece (2) is brought into the mouth and the telescopic duct (6) is extended.
  • 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.
  • 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 dewatering maneuver by means of the purge valve (3b).
  • the lower section (1) connects to the corrugated hoses (4) which, in addition to allowing air to pass through two paths, they enable the user to facilitate dewatering by compressing them with their hands and blowing through the nozzle (2) to force the water out through the purge valve (3b).
  • 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.
  • 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).
  • 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.
  • 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.
  • 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 degrees and 45 degrees, that is, between TT/36 rad and TT/45 rad, as shown in Figure 7.
  • the reason for this arching is to ensure the perpendicular positioning of the telescopic tube (6) in relation to the horizontal plane of the water surface.
  • the connection between the corrugated hoses (4) and the rods (5a) is made by movable connectors (5b) that allow fitting and unfitting to enable the placement of the equipment around the user’s neck (11).
  • the lower (1) and upper (5) sections, the telescopic duct (6) and the cover (8) may be made of plastic material, variations of PVC or any alloys that are of lightweight material.
  • the nozzle (2), the valve (3b), and the corrugated hoses (4) must be made of more flexible material such as silicone or rubber.
  • the telescopic neck 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 a bellows-style duct instead of the telescopic duct (6), capable of increasing in size by means of manual traction.

Abstract

Le présent modèle d'utilité concerne un équipement de plongée en surface connu sous le nom de tuba et mis au point pour augmenter la portabilité et la praticité des équipements déjà connus. Il est conçu pour être utilisé de manière indépendante d'un masque de plongée, présente la forme d'un collier (11) et, par conséquent, peut être transporté de manière confortable et pratique par l'utilisateur, lui permettant d'être toujours prêt pour la plongée, laquelle peut être réalisée avec ou sans utilisation d'un masque de plongée ou de lunettes de natation. L'embout (2) est raccordé au moyen d'une section inférieure (1) à deux tuyaux ondulés (4) qui contournent le cou de l'utilisateur (11) et qui sont reliés, au niveau de l'autre extrémité, à une section supérieure (5) où se trouve un conduit télescopique (6) prêt à être déployé au moment de la plongée pour atteindre l'air au-dessus de la surface de l'eau.
