Abstract: An aerodynamic fish lure facilitates collapsible closing of the lure for farther casting distance and accuracy when cast off in the air. The air casting event causes the lure's jointed segments to contract in length together in the air and then to expand in length as the lure hits the water. Then the lure either skims along the surface of the water or is submerged under the water and can pivot in two or more axial directions, or at any angles therebetween. Connectors connect the segments, and retract in or out of to respective recesses in the respective segments, which are designed to permit the collapsing of the length of the lure in the air as well as the lure's expansion or contraction in any axial direction or angle therebetween, in length in the water. The segments also laterally pivot, imitating wiggling of lure bait on or in the water.

Abstract: A locking device mounted in the interior portions of a mold includes a first member having an aperture therein adapted to be coupled to a first section of the mold, a second member having an aperture therein adapted to be coupled to a second section of the mold, the first and second members being alignable with one another so that the apertures therein can be aligned with each other, a pin being provided axially in one of the first and second members, the pin being radially compressible and being axially movable in the aperture in one of the members and being receivable in the aperture in the second of the members such that when the pin is axially moved into the aperture in the second section, the pin first compresses radially and then expands so as to be securely locked to the second member thereby locking the two members and the two sections of the mold together. A spring is preferably used to apply a force to keep the two sections tightly held together when in the locked condition.
