Abstract
A protective fairing encloses the head and torso of a SCUBA diver wearing diving equipment, with clearance throughout. A viewing shell section of the fairing covering the diver head is attached to a torso covering shell section to form a hydrodynamic shape facilitating forward underwater movement by reducing drag. Such torso shell section has vent holes formed therein to prevent water displacement within the fairing by air and is provided with buoyancy distributing weights to neutralize the effect of positive buoyancy during forward movement through seawater.
Claims5
An underwater protective fairing adapted for covering head and torso of a SCUBA diver wearing diving equipment, comprising:
- a shell having a head covering section for completely covering the head of the diver and a torso covering section extending from the head covering section at a location on the shell adjacent the head of the diver for enclosure of the head and the torso as well as the diving equipment, with clearance throughout, the torso shell section being made of a semi-rigid material having an end opposite said location on the shell of maximum cross-sectional fairing dimension forming an opening through which entry of the diver wearing the equipment is accommodated, vent means formed in the torso covering shell section spaced from said insertion opening for preventing water displacement by gas within the fairing;
- and buoyancy distributing weight means forwardly mounted in the torso covering shell section for neutralizing positive flotation buoyancy of the fairing in water during movement through seawater.
In combination with a fairing for protectively enclosing head and torso of a diver during movement underwater, said fairing having a head shell section extending from one axial end thereof and a torso shell section interconnected therewith with an insertion opening at an opposite axial end thereof for receiving the diver within the fairing, the improvement residing in:
- means for enhancing said underwater movement under positive buoyancy conditions, comprising:
- a plurality of weights;
- means for positioning said weights at a plurality of appropriately distributed axially spaced locations inside of the torso shell section to oppose upward forces on the fairing with the diver therein under said positive buoyancy conditions;
- and means mounted in the torso shell section for venting gas from the fairing during said underwater movement to prevent displacement of water there from through the insertion opening.

- means for enhancing said underwater movement under positive buoyancy conditions, comprising:
- a plurality of weights;
- and means for positioning said weights at a plurality of appropriately distributed axially spaced locations only inside of the torso shell section to oppose upward forces on the fairing with the diver therein under said positive buoyancy conditions.
