Abstract
A recovery buoy which is carried underwater by a diver and comprises an indented spool-like body of lightweight material around which is wrapped a cord. A weight is detachably mounted to the body and is attached to the cord so that the weight end of the cord can be attached to a structure to be recovered or marked, and when the body is released, its buoyancy causes it to rise, thereby unspooling the cord.
Claims19
A recovery and marker buoy, comprising:
- an enlongated body of buoyant material having axially opposite ends;
- a first flange member at one of said ends;
- a second flange member at the second one of said ends;
- a cylindrical central spindle intermediate said first and second flange members, said flange members including opposed frusto-conical surfaces interconnecting said flange members with said spindle;
- a location indicating head formed integrally with said first flange member on the axis of said body;
- a weight associated with said second flange member on the axis of said body;
- clamp means for detachably mounting said weight on said second flange member and being coupled to said weight;
- a line wound around said central spindle and having a first end, and a second end, said second end extending through said weight, in looped fashion, and being secured to said clamp means to securely retain said weight on the line second end upon detachment of said clamp means from said second flange member and dislodgement of said weight therefrom;
- and
- means for securing said first end of said line to said location indicating head and
- means for detachably mounting said weight to said second flange, whereby upon release of said weight from said second flange member and said body, anchoring of said weight at a selected location beneath water level may be effected and said line unreels from said central spindle under the buoyant force of said body, enabling the latter to freely float to the surface of the water, in which condition said location indicating head, upon surfacing, is operable to mark a location.
The recovery and marker buoy of claim 18 wherein said second flange member has an outer face and annular recess in said outer face and wherein, in assembled condition of the buoy, said anchoring members are accommodated in said recess. 20. The recovery and marker buoy of claim 19, wherein said anchoring members are pointed and of angular configuration.
