Abstract
Abstract A readily retractable sonar sensor system having a sensor carried by a rod slidably mounted in a sleeve which is located in spaced relation to the axis of rotation of a disc upon which the sleeve is fixedly supported, the latter extending normally to the radius of the disc. The disc is pivotally mounted on a plate which is supported by a C-clamp connected to its peripheral portion and mounted on a boat transom. Spring means surrounding the pivot pin urges the disc and plate together, causing matching projections on the disc to extend into openings in the plate to releasably control relative rotation therebetween, so that when the rod is swung to generally horizontal orientation, the sensor swings rearwardly and upwardly out of the water.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
297 words
A readily retractable sonar sensor system comprising: (a) a support plate member; (b) clamping means carrying said plate member and constructed and arranged to clamp the transom of a fishing boat and thereby support said plate member in rearwardly generally vertically extending position relative to such a transom; (c) a mounting disc member extending substantially parallel to and beside said plate member; (d) a pivot pin carried by said plate member rearwardly of said clamping means and of the boat and rotatably mounting said disc member thereon for rotation of said disc member about an axis located centrally of the latter and closely adjacent said clamping means; (e) spring bias means carried by said pivot pin and urging said members toward each other; (f) a sleeve fixedly mounted on said disc member laterally of said pivot pin and on the side of said disc member non-adjacent to said plate member and having its axis extending generally parallel to said disc member; (g) a sonar sensor support rod slidably mounted within said sleeve for longitudinal shifting thereof axially of said sleeve to permit vertical adjustment of said rod; (h) means for adjustably securing said support rod within said sleeve; (i) a sonar sensor mounted on the lower end of said support rod; and, (j) cooperative releasable catch means carried by said members and normally holding said disc member from rotating about said pivot pin while said sensor is held in depending position by said support rod, said plate and disc members being constructed and arranged to permit said sensor to be readily swung upwardly away from the boat about the axis of said pivot pin and held by said catch means in an elevated out-of-way position by pulling forwardly on the upper end portion of said support rod.
Claim 2
Dependent Claim
297 words
A readily retractable sonar sensor system comprising: (a) a support plate member; (b) clamping means carrying said plate member and constructed and arranged to clamp the transom of a fishing boat and thereby support said plate member in rearwardly generally vertically extending position relative to such a transom; (c) a mounting disc member extending substantially parallel to and beside said plate member; (d) a pivot pin carried by said plate member rearwardly of said clamping means and of the boat and rotatably mounting said disc member thereon for rotation of said disc member about an axis located centrally of the latter and closely adjacent said clamping means; (e) spring bias means carried by said pivot pin and urging said members toward each other; (f) a sleeve fixedly mounted on said disc member laterally of said pivot pin and on the side of said disc member non-adjacent to said plate member and having its axis extending generally parallel to said disc member; (g) a sonar sensor support rod slidably mounted within said sleeve for longitudinal shifting thereof axially of said sleeve to permit vertical adjustment of said rod; (h) means for adjustably securing said support rod within said sleeve; (i) a sonar sensor mounted on the lower end of said support rod; and, (j) cooperative releasable catch means carried by said members and normally holding said disc member from rotating about said pivot pin while said sensor is held in depending position by said support rod, said plate and disc members being constructed and arranged to permit said sensor to be readily swung upwardly away from the boat about the axis of said pivot pin and held by said catch means in an elevated out-of-way position by pulling forwardly on the upper end portion of said support rod.
Claim 3
Dependent Claim
64 words
The structure defined in claim 1, wherein said catch means is so constructed and arranged that the axis of said sleeve and said rod, when the lower end of the latter is moved to latched depending position, extends at a somewhat obtuse angle relative to a horizontal plane extending normal to and forwardly from the boat transom to which said clamping means is secured.
Claim 4
Dependent Claim
25 words
The structure defined in claim 1 wherein said clamping means is comprised of a C-clamp connected to the peripheral edge portions of said plate member.
Claim 5
Dependent Claim
74 words
The structure defined in claim 1 wherein said catch means is comprised of a plurality of recesses formed in one of said members and arranged radially equidistantly around said pivot pin, and a plurality of projections carried by the other of said members and also arranged radially equidistantly around said pivot pin and positioned correspondingly therearound on each of said members and extending into said recesses to releasably hold said members against relative rotation.
Claim 6
Dependent Claim
32 words
The structure defined in claim 1 wherein said sleeve member extends substantially normally of a radius of said disc member and is located a substantial distance radially outwardly of said pivot pin.
Claim 7
Dependent Claim
