Abstract
Abstract A boat hook is provided with a series of attachments engagable with a coupling device on the prod end. The coupling preferably includes a threaded section, and is set back from the point of the prod for the dual purpose of protecting the threads, and for utilizing the point as the means of assuring positive coaxial alignment of the coupling. The attachments provide a variety of areas of utility, and the preferred form of the invention has a telescoping handle capable of being locked in a plurality of degrees of extension appropriate to the particular attachments that may be coupled to the basic device. The original utility of the boat hook is not impaired by the provision for the attachments. One of the attachments is a hoop with a provision for temporarily retaining a loop in a mooring line.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
97 words
A marine implement including a boat hook having an elongated handle portion extending along a handle axis, a hook portin extending laterally from said axis, and a prod portion extending parallel to said axis on the opposite side of said hook portion from said handle portion, wherein the improvement comprises: coupling means on said prod portion coaxial therewith, including a threaded portion, said prod portion having a point extending substantially beyond said coupling means; and at least one attachment engageable with said coupling means, and having a socket in which part of said prod portion is receivable.
Claim 2
Dependent Claim
97 words
A marine implement including a boat hook having an elongated handle portion extending along a handle axis, a hook portin extending laterally from said axis, and a prod portion extending parallel to said axis on the opposite side of said hook portion from said handle portion, wherein the improvement comprises: coupling means on said prod portion coaxial therewith, including a threaded portion, said prod portion having a point extending substantially beyond said coupling means; and at least one attachment engageable with said coupling means, and having a socket in which part of said prod portion is receivable.
Claim 3
Dependent Claim
22 words
An implement as defined in claim 1, wherein said socket receives said prod portion on both axial sides of said threaded portion.
Claim 4
Dependent Claim
23 words
An implement, as defined in claim 2, wherein said prod portion tapers to increased diameter from said threaded portion toward said hook portion.
Claim 5
Dependent Claim
178 words
A marine implement including a boat hook having an elongated handle portion extending along a handle axis, said handle portion having telescoping sections and locking means operable to secure at least two degrees of extension of said telescoping sections, said implement also including a hook portion extending laterally from said axis, and a prod portion extending parallel to said axis on the opposite side of said hook portion from said handle portion, wherein the improvement comprises: coupling means on said prod portion coaxial therewith, said prod portion having a point extending substantially beyond said coupling means; at least one attachment engageable with said coupling means, and having a socket in which part of said prod portion is receivable; and a transverse detent constituting said locking means, said detent being carried by the inner of said telescoping sections, said detent being engageable with apertures in the outer of said telescoping sections, and additionally including means mounted on said outer section providing an interior annular recess engageable with said detent means to limit the possible extension of said telescoping sections.
Claim 6
Dependent Claim
178 words
A marine implement including a boat hook having an elongated handle portion extending along a handle axis, said handle portion having telescoping sections and locking means operable to secure at least two degrees of extension of said telescoping sections, said implement also including a hook portion extending laterally from said axis, and a prod portion extending parallel to said axis on the opposite side of said hook portion from said handle portion, wherein the improvement comprises: coupling means on said prod portion coaxial therewith, said prod portion having a point extending substantially beyond said coupling means; at least one attachment engageable with said coupling means, and having a socket in which part of said prod portion is receivable; and a transverse detent constituting said locking means, said detent being carried by the inner of said telescoping sections, said detent being engageable with apertures in the outer of said telescoping sections, and additionally including means mounted on said outer section providing an interior annular recess engageable with said detent means to limit the possible extension of said telescoping sections.
Claim 7
Dependent Claim
133 words
A marine implement including a boat hook having an elongated handle portion extending along a handle axis, a hook portion extending laterally from said axis, and a prod portion extending parallel to said axis on the opposite side of said hook portion from said handle portion, wherein the improvement comprises: coupling means on said prod portion coaxial therewith, said prod portion having a point extending substantially beyond said coupling means; and at least one attachment engageable with said coupling means, and having a socket in which part of said prod portion is receivable, said attachment including a loop frame disposed with the axis thereof in a plane substantially parallel to said handle axis, and a plurality of projections from said loop frame extending laterally from said plane on at least one side thereof.
Claim 8
Dependent Claim
133 words
A marine implement including a boat hook having an elongated handle portion extending along a handle axis, a hook portion extending laterally from said axis, and a prod portion extending parallel to said axis on the opposite side of said hook portion from said handle portion, wherein the improvement comprises: coupling means on said prod portion coaxial therewith, said prod portion having a point extending substantially beyond said coupling means; and at least one attachment engageable with said coupling means, and having a socket in which part of said prod portion is receivable, said attachment including a loop frame disposed with the axis thereof in a plane substantially parallel to said handle axis, and a plurality of projections from said loop frame extending laterally from said plane on at least one side thereof.
Claim 9
Dependent Claim
17 words
An implement as defined in claim 5, wherein said projections diverge with increased distance from said plane.
Claim 10
Dependent Claim
89 words
A marine implement for use in mooring procedures, said implement comprising: a loop frame having an axis disposed substantially in one plane; handle means extending from said loop frame substantially parallel to said plane; and line-retaining means fixed with respect to said loop frame whereby a loop at the end of a line may be retained on said line-retaining means by application of tension in said line in the direction of said handle, said line-retaining means including a plurality of projections extending from said plane on one side thereof.
Claim 11
Dependent Claim
89 words
A marine implement for use in mooring procedures, said implement comprising: a loop frame having an axis disposed substantially in one plane; handle means extending from said loop frame substantially parallel to said plane; and line-retaining means fixed with respect to said loop frame whereby a loop at the end of a line may be retained on said line-retaining means by application of tension in said line in the direction of said handle, said line-retaining means including a plurality of projections extending from said plane on one side thereof.
