Definitions

  • 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.
  • 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.
  • 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.
  • the present disclosure relates to an underwater walking helmet for a user comprising; a quick release valve with one way non return valve; a plurality of slidable weights distributed equally over each shoulder of the user; and a quick release clasp for joining a plurality of straps.
  • the quick release valve with one way non return valve comprises an air supplying hose with coupling and a receptacle means to hold the air supplying hose with coupling.
  • the plurality of slidable weights comprises a spherical and smooth metal balls as weights, fabricated in a box and attached to the fibre reinforced plastic material.
  • the quick release clasp for joining a plurality of straps comprises a single click fastener.
  • a plurality of track sliding means for sliding the plurality of weights is also disclosed.

  • 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.

Abstract

La présente invention concerne un casque de marche sous l'eau pour un utilisateur comprenant : un clapet à libération rapide doté d'un clapet anti-retour à sens unique ; une pluralité de poids coulissants répartis de manière égale sur chaque épaule de l'utilisateur ; et une attache à libération rapide pour relier une pluralité de sangles. Le clapet à libération rapide doté d'un clapet de non-retour à sens unique comprend un tuyau d'alimentation en air doté d'un accouplement et d'un moyen de réceptacle en vue de maintenir le tuyau d'alimentation en air doté d'un accouplement. La pluralité de poids coulissants comprend des billes métalliques sphériques et lisses en tant que poids, fabriquées dans une boîte et fixées à la matière plastique renforcée par des fibres. Le clapet à libération rapide comprend un élément de fixation à simple clic pour joindre une pluralité de sangles. L'invention concerne également une pluralité de moyens de coulissement sur rail pour faire coulisser la pluralité de poids. En outre, le casque comprend une vitre constituée d'un matériau acrylique.
