Abstract
An underwater motive device provides an integrated and modular battery and motive housing which is carried within an outer housing and secured by a nose cone system. The nose cone system works against an “o” ring seal carried between a structure of the integrated and modular battery and motive housing and the outer housing. A pair of latches act as levers to forcibly push the nose cone in place to seal off the battery compartment, and with cam action when used to urge the nose cone to a disengaged position with respect to the “o” ring seal. Nose cone removal and re-sealing procedure can be accomplished easily, even by those of limited strength.
Claims11
An underwater motive device comprising:
- an outer rear housing including a pair of oppositely located integral side handles;
- an inner core having a forward battery chamber connected to a rearward motor compartment;
- a motor within said inner core and having a shaft extending out of said inner core, and wherein removal of said inner core enables simultaneous removal of said forward battery chamber and said rearward motor compartment and said motor;
- a battery carried and substantially enclosed by said forward battery chamber of said inner core;
- switch means, carried by said outer rear housing and operably connected between said battery and said motor, for actuating said motor;
- a propeller carried by said shaft;
- and
- a front nose cone attached to at least one of said outer rear housing and said inner core, to seal said forward battery chamber against moisture.
