  • Fishing lure oscillator
    Patent number: 7493724
    Abstract: A fishing lure oscillator, comprising a bent, oblonged, essentially elliptical foil having relatively uniform thickness. Near one end of the foil, a connection is made to an appendage, and near the opposite end of the foil a connection is made to another appendage. Both appendages, serving as a framing device to support the foil, originate from a common base which is adapted to be joined with a fishing lure. When joined with a lure and pulled through a body of water, an outwardly contoured portion of the foil is disposed directly against the flow of water whereby the force of water against the resisting face of the foil causes the foil to pivot freely within the framing device, thus transferring the resulting oscillation to the lure for the purpose of attracting and catching fish.

  • Latching mechanism with trigger actuator
    Patent number: 7370891
    Abstract: A latching mechanism for a carrying case includes a latch body pivotally attached to a top cover of the case, a trigger pivotally attached to the latch body, and an actuator that pivots about the same axis as the trigger. The trigger is pivotable between a latching position for keeping the latch body closed, and a release position to allow the case to be opened. The actuator is pivotable toward and away from a nominal actuator position in which a panel of the actuator assumes a predetermined alignment with the latch body. A torsion spring biases the trigger toward the latching position, and through trigger/actuator contact biases the actuator into the nominal position. The trigger can move toward the release position while the actuator is held in the nominal position, to maintain the selected alignment for a more natural, intuitive latching mechanism closure.
