Thermal dual-layer undergarment for a dry diving suit

Abstract

A thermal insulating garment for an underwater diving suit has an inner insulating layer or thermal core and an outer elastomeric layer. The inner thermal core layer is larger than the outer layer. The inner thermal core thermal layer is temporarily fixed to the outer elastomeric layer by fastening means such as a hook and loop system. A zipper may be disposed between the two shoulders of the garment and across the chest of the garment to permit the top portion of the garment to be removed and permit diver entry and egress into the dry suit. There is a lamination seal at the ankles, wrists and collar of the garment.

Description

TECHNICAL FIELD[0001]This invention relates to underwater diving equipment and more particularly to dry diving suits worn by professional and sports divers for warmth and protection while diving, and specifically a new thermal two-layer undergarment for a dry diving suit.BACKGROUND ART[0002]Underwater diving in cold water requires a dry diving suit that is capable of insulating the diver from the temperature of the ambient water and its deleterious effects. A dry suit provides physical protection against water and obstacles that a diver may encounter. However, in cold water dives it is necessary for the diver to wear additional garments underneath the dry suit to keep warm. Wet suits, on the other hand, permit water to enter the suit forming a layer of water trapped between the diver's body and the suit. Once the water is trapped it is heated by the diver's body and provides a layer of insulation around the diver. Each of these systems has deficiencies.[0003]Wet suites are unsuitabl...

AI Technical Summary

Benefits of technology

The invention provides an insulating undergarment for divers that can be made in limited sizes to save manufacturing costs and inventory. The garment has a fleece inner layer and a LYCRA outer layer. The outer layer can be a high stretch material like neoprene or a stretch mesh. The layers of the garment can be attached or just placed over each other. The technical effect is a more efficient and cost-effective insulating undergarment for divers.

Problems solved by technology

Each of these systems has deficiencies.

Wet suites are unsuitable for cold water dives primarily because they allow water to come into contact the diver.

Dry suits can be very cumbersome and stiff and so restrict the movement of the diver underwater.

Such a device requires additional equipment for the diver to carry during a dive and may increase the cumbersome nature of the diving suit.

Furthermore, the bladders may make ingress and egress from a dry suit more difficult for the diver.
