Inflatable diving safety marker

Abstract

The present invention is an inflatable safety marker for a diver comprising a cylindrical hollow housing having a lid, a puncture plate, an inflatable bladder and a length of line connecting the bladder to the housing. The lid is hingably affixed to one end of the housing. The puncture plate is affixed within the housing below the lid. The puncture plate comprises a pierce needle positioned at the center with the sharp end exposed on the lower surface of the plate and the other end of the pierce needle exposed on the upper surface of the plate. The puncture plate also has a threaded cylindrical skirt depending from the lower surface about the sharp end of the pierce needle. The threaded cylindrical skirt is able to receive a threaded end of a canister containing gas for inflating the bladder. The inflatable bladder is positioned on the upper surface of the puncture plate with its open end removably affixed to the other end of the pierce needle. A length of line connects the bladder to the housing.

Benefits of technology

[0018]In another embodiment the bladder of the inflatable safety marker has a reflective surface able to reflect light or a radio frequency signal. The light reflected may be visible of infrared light.

[0019]Another aspect of the present invention is a method of deploying the inflatable safety marker. The method comprises the steps of twisting the gas canister, or lower portion of the housing affixed to the base of the canister, in a clockwise direction with respect to the housing or upper portion of

Problems solved by technology

A variety of markers designed to indicate the location of a submerged diver have been provided, however none addresses the needs of a diver in distress.

Unfortunately, the marker requires that the diver manually inflate the buoy through the valve means, which may not be possible if a diver is in distress.

In addition, such a device adds unnecessary weight to a diver's equipment that may not be easily released in an emergency for an immediate ascent.

Like U.S. Pat. No. 5,141,458, this device also requires manual inflation and the reel adds unnecessary weight to the diver's equipment.

The disadvantage of this device is that because it does not have an inflatable floatation element it is not compact.

Its size is cumbersome and adds an additional element to the d
