Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
129 words
A boat handler device comprising: a tubular handle; a sleeve element fixedly and coaxially secured in one end of said tubular handle and having a radially extending anvil portion; a hook element having a shaft extension running coaxially through said sleeve element and rotationally movable in said sleeve to selectively close on said anvil portion of said sleeve; a stop block secured to the end of said shaft extension for rotation therewith and bearing against said sleeve in prevention of withdrawal of said hook element from said sleeve and limiting rotation of said hook in relation to said sleeve element; and detent means intermediate said sleeve and said stop block parallel to the axis of said sleeve and providing one or more selected stop positions for said hook rotation.
Claim 2
Dependent Claim
129 words
A boat handler device comprising: a tubular handle; a sleeve element fixedly and coaxially secured in one end of said tubular handle and having a radially extending anvil portion; a hook element having a shaft extension running coaxially through said sleeve element and rotationally movable in said sleeve to selectively close on said anvil portion of said sleeve; a stop block secured to the end of said shaft extension for rotation therewith and bearing against said sleeve in prevention of withdrawal of said hook element from said sleeve and limiting rotation of said hook in relation to said sleeve element; and detent means intermediate said sleeve and said stop block parallel to the axis of said sleeve and providing one or more selected stop positions for said hook rotation.
Claim 3
Dependent Claim
21 words
In the boat handler of claim 1 including an eye provided on the end of the handle remote from said hook.
Claim 4
Dependent Claim
38 words
In the boat handler of claim 1 wherein said tubular handle is locked drivably for rotation of said sleeve to a handle extension inserted in said tubular handle and drivably secured thereto for transmitting rotational and axial fOrce.
Claim 5
Dependent Claim
148 words
A boat handler device comprising: an elongate handle; a tubular sleeve extending from said handle; an anvil piece coaxially supported in said tubular sleeve and the anvil portion thereof extending radially therefrom; a hook element having a shaft portion extension passing axially through said anvil piece whereby said hook portion is rotatable toward and away from closure against said anvil; a stop block element secured to the end of said shaft portion of said hook in prevention of withdrawal of said shaft portion of said hook from said anvil piece and said stop block in contact with said anvil piece at the end next adjacent said handle; and detent means parallel to the axis of said sleeve including a spring located intermediate said stop block and said handle end of said anvil piece whereby rotation of said hook is detentably oriented at an open and a closed position.
Claim 6
Dependent Claim
148 words
A boat handler device comprising: an elongate handle; a tubular sleeve extending from said handle; an anvil piece coaxially supported in said tubular sleeve and the anvil portion thereof extending radially therefrom; a hook element having a shaft portion extension passing axially through said anvil piece whereby said hook portion is rotatable toward and away from closure against said anvil; a stop block element secured to the end of said shaft portion of said hook in prevention of withdrawal of said shaft portion of said hook from said anvil piece and said stop block in contact with said anvil piece at the end next adjacent said handle; and detent means parallel to the axis of said sleeve including a spring located intermediate said stop block and said handle end of said anvil piece whereby rotation of said hook is detentably oriented at an open and a closed position.
Claim 7
Dependent Claim
52 words
In the boat handler device of claim 4 wherein said detent means includes a spring pocket in said anvil piece into which said spring is located and pockets in said stop block at one or more extremes of rotation; and a ball faced element biased by said spring toward said stop block.
