Deep diving fishing lure

1. A deep diving fishing lure, comprising:

an elongate lure body having head and tail portions, a topside, an underside, and a longitudinal axis;

a diving lip extending away from the head portion at a downward angle relative to the longitudinal axis of the lure body,

said diving lip having a top surface, a bottom surface, a front portion, and a rear portion;

a fore-and-aft pivotable lure positioning arm pivotalby mounted to the diving lip and extendable above the top surface of the diving lip, the lure positioning arm terminating at a distal end thereof in an eyelet for attachment of a fishing line;

a catch adapted to releasably engage the lure positioning arm, wherein:

the catch releasably holds the lure positioning arm in a fixed aft position causing the lure to dive downwardly when pulled through the water by a fishing line attached to the lure positioning arm and releases the lure positioning arm when a fish strikes the lure; and

at least one eyelet extending from said underside of said lure body for attachment of a fishing hook; wherein:

the lure positioning arm pivots about an axis located at the front portion of the diving lip less than about 1/10 of a length of the diving lip away from a front edge thereof.

2. A lure as in claim 1 , wherein:

an additional eyelet for attaching a fish hook extends from said tail portion of said lure body.

3. A lure as in claim 1 , wherein:

a width of said diving lip increases from said front portion to a maximum at a point intermediate the length of the diving lip, and thereafter decreases until the rear portion thereof adjoins the lure body,

wherein a maximum lateral width of said diving lip is greater than a lateral width of said lure body.

4. A lure as in claim 1 , further comprising:

a fin protruding from the bottom surface of said diving lip extending longitudinally from near a midpoint of the bottom surface of the diving lip to the rear portion of said diving lip.

5. A lure as in claim 1 , wherein:

the catch has a pair of spaced opposed cusps capable of back-and-forth movement relative to one another; and

a fastener for adjusting spacing between the cusps is operably associated with the cusps.

6. A lure as in claim 5 wherein:

the fastener is a socket cap screw that passes through the cusps and is threadedly engaged with a nut embedded in one of the cusps.

7. A deep diving fishing lure, comprising:

an elongate lure body having head and tail portions, a topside, an underside, and a longitudinal axis;

a diving lip extending away from the head portion at a downward angle relative to the longitudinal axis of the lure body,

said diving lip having a top surface, a bottom surface, a front portion, and a rear portion;

a fore-and-aft pivotable lure positioning arm pivotably mounted to the diving lip and extendable above the top surface of the diving lip, the lure positioning arm terminating at a distal end thereof in an eyelet for attachment of a fishing line;

a catch adapted to releasably engage the lure positioning arm, wherein:

the catch releasably holds the lure positioning arm in a fixed aft position causing the lure to dive downwardly when pulled through the water by a fishing line attached to the lure positioning arm and releases the lure positioning arm when a fish strikes the lure; and

at least one eyelet extending from said underside of said lure body for attachment of a fishing hook; wherein:

said top surface of the diving lip defines a longitudinally extending groove;

a catch having a pair of opposed cusps within said groove is positioned so that a top of said catch is flush with said top surface of the diving lip; and

said lure positioning arm is received within said groove.

8. A fishing lure, comprising:

an elongate lure body having first and second end portions, a topside and an underside, and a longitudinal axis;

a diving lip extending from said first end portion of said lure body, and having a width and a length along the longitudinal axis of the lure body greater than the width,

said diving lip having a top surface defining a diving plane, a bottom surface, and front and rear portions;

a latch located on said top surface of said diving lip, said latch including a fore-and-aft pivotable lure positioning arm extendable above the top surface of the diving lip and an adjustable catch for the lure positioning arm, the lure positioning arm being adapted for attachment to a fishing line, the catch releasably holding the lure positioning arm in a fixed aft position causing the lure to dive downwardly when pulled through the water by a fishing line attached to the lure positioning arm; and

at least one eyelet extending from the underside of said lure body for attachment of a fishing hook;

said adjustable catch having a pair of adjustably spaced, opposed cusps and a socket cap screw that passes through the cusps and is threadedly engaged with a nut embedded in one of the cusps for adjusting the space between the opposed cusps.
