Latest Patents
One of his latest inventions is the leg extension assembly. This invention comprises an outer sleeve member with a box leg member disposed within it. It features a telescopically collapsible inner leg member that is slidably mounted within the sleeve member. The design includes means for connecting the box leg member to the inner leg member, which incorporates a spring element that biases the inner leg member away from the box leg. Additionally, it has locking means for securing the inner leg at a selected extended length. This leg extension assembly can be integrated into a leg element or attached to existing legs of structures such as ladders, scaffolds, sawhorses, tables, or chairs.
Another significant patent is the drive belt release mechanism for magnetic disk drives. This mechanism is designed to disengage a drive belt from a spindle drive pulley and engage it back onto the pulley. To disengage the belt, the mechanism lifts it from the drive pulley while allowing the drive motor to pivot, relieving the tension in the drive belt. Conversely, to engage the belt, the mechanism seats it on the pulley and forces the motor into a drive position, achieving the desired tension in the belt. This mechanism is entirely mechanical and can be operated manually.
