Abstract
Abstract The swivel mount of the present invention provides a low profile swivel for a deep trolling reel which can be permanently secured to the deck of a vessel and provides incremental rotational adjustment of the deep trolling reel mounted thereto through 360° at 45° intervals in the preferred embodiment. The structure compactness is made possible by the use of interengaging locking mechanism extending upwardly from a base plate to engage a plurality of angularly spaced notches communicating with the outer periphery of an annular groove in a swivel plate pivotally mounted to the base plate. The locking mechanism is spring-loaded and includes a control handle extending outwardly from the base plate to releasably lock the deep troller in a desired position.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
165 words
A swivel assembly for mounting a downrigger to a vessel comprising: a base plate including means for securing said plate to a vessel, said plate having an upper surface and a first recess formed downwardly in said plate through said upper surface, interengaging means movably positioned in said recess and including a portion extending above said upper surface; a swivel plate rotatably secured to said base plate and including a lower surface facing said upper surface of said base plate, said swivel plate including a second recess for receiving said portion of said interengaging means to permit relative rotation of said swivel plate with respect to said base plate when said interengaging means is in a first position, said swivel plate including locking means communicating with said second recess; and means for moving said interengaging means to a second position in which said portion of said interengaging means contacts said locking means to prevent rotation of said swivel plate with respect to said base plate.
Claim 2
Dependent Claim
165 words
A swivel assembly for mounting a downrigger to a vessel comprising: a base plate including means for securing said plate to a vessel, said plate having an upper surface and a first recess formed downwardly in said plate through said upper surface, interengaging means movably positioned in said recess and including a portion extending above said upper surface; a swivel plate rotatably secured to said base plate and including a lower surface facing said upper surface of said base plate, said swivel plate including a second recess for receiving said portion of said interengaging means to permit relative rotation of said swivel plate with respect to said base plate when said interengaging means is in a first position, said swivel plate including locking means communicating with said second recess; and means for moving said interengaging means to a second position in which said portion of said interengaging means contacts said locking means to prevent rotation of said swivel plate with respect to said base plate.
Claim 3
Dependent Claim
35 words
The apparatus as defined in claim 1 wherein said interengaging means comprises a slide positioned in said first recess and wherein said portion of said interengaging means comprises an upwardly extending segment of said slide.
Claim 4
Dependent Claim
26 words
The apparatus as defined in claim 2 wherein said locking means comprises a plurality of spaced notches shaped to cooperatively interengage said segment of said slide.
Claim 5
Dependent Claim
29 words
