DETAILED DESCRIPTION

[0021] With reference to the drawings wherein like numerals represent like parts throughout the figures, a fishing gaff is generally designated by the numeral 10. The fishing gaff includes a hook 20 and a tubular shaft 30 constructed from sturdy materials of high structural integrity so as to be capable of landing gamefish of significant magnitude. The fishing gaff 10 functions to allow the hook 20 to be selectively released from the shaft 30 upon manual actuation by the operator, as will be detailed below. The shaft 30 has multiple components, including an outer tube 32 and a tubular extension 34.

[0022] With reference to FIGS. 4, 6 and 7, the hook 20 has a compound bend with a rod-like axial shank 22. The shank 22 includes a recessed locking groove 24 which preferably circumferential extends around the shank axis and has a uniform depth and axial dimension. The shank terminates in a nose-like terminus 26. The hook 20 may also include an eyelet 28 for attachment of a lanyard (not illustrated) to retain the hook upon release from the shaft 30.

[0023] A coupler 40 includes a base 42 having a circumferential thread 44 which threads into one end of the tubular shaft 30. The coupler 40 has a central axial bore 46 which closely receives the hook shank 22. With additional reference to FIGS. 8 and 9, a plurality of pivotal arm-like jaws 50 each have an intermediate locking lug 52. Each lug 52 is dimensioned and positioned to engage into the locking groove 24 of the hook shank. The jaws 50 are pivotally mounted to the coupler base 42 and/or are resiliently biased toward each other and toward the axial center line of the receiving bore 46. Two, three, four or other numbers of locking jaws may be provided. The distal end 54 of each of the jaws has a smooth contoured surface. When the hook shank 22 is inserted into the receiving bore 46 of the coupler, the jaws 50 are biased inwardly and each end 54 is contoured so that each locking lug 52 rides over the shank until it aligns with the locking groove 24, in which instance, the lugs 52 are biased for engagement into the locking groove to lock the hook to the shaft in a fixed axial position.

[0024] With additional reference to FIGS. 4 and 8, a release assembly 60 includes an elongated tube 62 of reduced diameter relative to tube 32 is disposed inside and generally coaxial with the outer tube 32. Tube 62 is adapted for limited longitudinal displacement within tube 32. The distal end of the release tube interiorly threadably connects with a quasi-bullet-shaped actuator 70. The actuator 70 has a generally cylindrical surface 72 which extends from an annular shoulder 74 with a reduced diameter and terminates in a truncated conical end surface 76 (FIGS. 8 and 9). The end surface inwardly tapers and terminates in a substantially snub nose 78 which axially engages between the ends of the jaws 50. When the release tube 62 and the actuator 70 carried by the tube are longitudinally displaced toward the hook, the actuator 70 engages between the interior end portions of the jaws 50 and the conical surface 76 forces the jaws to spread apart radially so that the lugs 52 disengage from the locking groove 24 and the hook 20 may be released from the shaft of the gaff.

[0025] A quasi-cylindrical connector 80 includes a pair of longitudinally spaced threaded surfaces 82 and 84 which thread into the interior outer shaft tube 32 and a tubular extension 34 which secures the coupler 40 to the shaft 30. A coil spring 86 is engageable against an interior shoulder 88 of the connector and against a shoulder of the actuator 70 to spring bias the release assembly 60, including the tube 62, toward the proximal end of the outer tubular shaft 32.

[0026] With additional reference to FIGS. 5, 8 and 9, a release button assembly 90 includes a cap 92. The cap 92 has an interior threaded surface 94 which threads to the outer end of the tubular shaft 32. A button 96 is received in an interior outer annulus of the cap and has a cylindrical inner wall 98 which threads into the interior end of the release tube 62. It will be appreciated that the button 96 is axially biased to an outer axial position. The button 96 may then be longitudinally moved axially or depressed toward the hook end so that the actuator 70 engages the jaws 50 to release the locking engagement of the hook 20. In the normal locked position, the button 96 is projected axially outwardly from the cap (FIG. 12). The spring 86 preferably exerts a significant force resisting depression of the release button 96 so that separation of the hook 20 is intentional on the part of the user and not inadvertent.

[0027] As best illustrated in FIG. 8, when the hook is locked to the shaft assembly, the actuator 70 is axially displaced from the jaws 50, and the button is in an extended position. As illustrated in FIG. 9, when it is desired to release the hook, the button is depressed in the direction of the lower FIG. 9 arrow. The latter forces the actuator 70 to engage the locking jaws 50 and force them outwardly, as illustrated by the opposed arrows and release the hook 20.

[0028] The hook shank 22 may then be reinserted into the coupler 40 and the locking jaws 50 reengage for securely locking the hook 20 to the shaft 30.

[0029] In an alternative embodiment, the lock/release modes may be reversed. The release button or operator is depressed by the user to maintain a lock mode for the hook, and released to separate the hook from the shaft. For this embodiment, the fisherman holds the operator while the hook is in the fish and then releases the hook from the shaft. Release mechanisms which employ operators other than buttons may also be incorporated into the fishing gaff.

[0030] While preferred embodiments of the foregoing have been set for purposes of illustration, the foregoing description should not be deemed a limitation of the invention herein. Accordingly, various modifications, adaptations and alternatives may occur to one skilled in the art without departing from the spirit and the scope of the present invention.
