Floating Hand Tool Handle Buoyancy and Seal Design

The patent applies the anti-weight principle by incorporating buoyant elements that counteract the sinking tendency of the hand tool. The grip assembly includes a buoyant body or air-filled chamber that provides upward buoyant force, effectively creating a counterweight system that balances the tool's weight and enables it to float on water surface.

The patent employs composite materials by combining traditional tool materials with buoyant materials. The grip assembly integrates non-conductive handle material with buoyant elements (such as foam or air-filled chambers), creating a composite structure that maintains tool functionality while adding floating capability. This composite approach allows the tool to operate normally while preventing sinking.

The patent applies flexible shells and thin films by using a flexible seal member (such as an O-ring or gasket) that conforms to the interface between the buoyant body and the tool shaft. This flexible sealing element creates a water-tight barrier that prevents leakage while accommodating the buoyant structure, ensuring both floating reliability and leak prevention.

The patent uses an intermediary sealing element as a mediator between the buoyant body and the tool shaft. This intermediate seal member (such as a compressible gasket or O-ring) fills the interface gap, creating a water-tight connection that prevents harmful water ingress while maintaining the buoyant floating capability.
