Abstract
Abstract A device for use with a conventional loop-provided boat line to effect docking or mooring of boats comprising a pair of rigid arms for detachable engagement upon opposed portions of the strands of the loop near the base thereof; there being a pivotal connection between each of the rigid arms adjacent their rearward or loop remote ends for swingable movement of the same away from and toward each other, or into open or closed condition, respectively. The rearward ends of these arms are formed to provide cooperating jaws for clamping relationship upon an interposed implement as the arms are moved away from each other for loop opening through a pulling force upon the line.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
152 words
The combination of a flexible boat line having a loop formed in one end portion thereof encirclable about a mooring device, said loop having a base portion with opposing strands progressing therefrom, and of a docking device comprising a pair of rigid arms in correspondence to said strands, each arm having outer and inner ends, the outer ends of said arms terminating spacedly inwardly of the bight portion of said loop, means securing each of said arms rigidly on the related line strand, said securing means inhibiting relative movement of said arms with respect to the engaged strands so that the same at all times act unitarily, said arms having their inner ends relatively proximate said loop base portion, and means pivotally interengaging said arms at their inner end portions premitting swinging of the same together with the engaged portions of said strands away from each other for opening of said loop.
Claim 2
Dependent Claim
152 words
The combination of a flexible boat line having a loop formed in one end portion thereof encirclable about a mooring device, said loop having a base portion with opposing strands progressing therefrom, and of a docking device comprising a pair of rigid arms in correspondence to said strands, each arm having outer and inner ends, the outer ends of said arms terminating spacedly inwardly of the bight portion of said loop, means securing each of said arms rigidly on the related line strand, said securing means inhibiting relative movement of said arms with respect to the engaged strands so that the same at all times act unitarily, said arms having their inner ends relatively proximate said loop base portion, and means pivotally interengaging said arms at their inner end portions premitting swinging of the same together with the engaged portions of said strands away from each other for opening of said loop.
Claim 3
Dependent Claim
20 words
The combination defined in claim 1 and further characterized by said arm mounting means permitting ready detachability of said arms.
Claim 4
Dependent Claim
25 words
The combination defined in claim 2 and further characterized by said arm mounting means being lacing threaded about said arms and the associated line strand.
Claim 5
Dependent Claim
43 words
The combination defined in claim 1 and further characterized by each of said arms having an outwardly opening substantially coextensive groove for receiving the inner portion of the related line strand and means for limiting the movement of said arms toward each other.
Claim 6
Dependent Claim
33 words
The combination defined in claim 4 and further characterized by said arms being mounted upon the related line strands so as to present their loop base proximate ends spacedly from the loop base.
Claim 7
Dependent Claim
51 words
The combination defined in claim 1 and further characterized by a plate portion being provided upon each arm in the end portion thereof proximate the loop base, the plate portions of said arm being disposed in planar parallel relationship, said means pivotally interengaging said arms being provided within said plate portions.
Claim 8
Dependent Claim
33 words
The combination defined in claim 6 and further characterized by said plates having a leading edge, a lateral edge, and a trailing edge, said trailing edge contoured to define an end opening recess.
Claim 9
Dependent Claim
51 words
The combination defined in claim 7 and further characterized by said trailing edge recess being of general V-shape having converging edge portions whereby upon outward swinging of said arms, edge portions of the trailing edge of the said plate portions will move toward each other in the manner of clamping jaws.
Claim 10
Dependent Claim
23 words
The combination defined in claim 8 and further characterized by edge portions of the trailing edge of said plate portions having concave indentations.
Claim 11
Dependent Claim
41 words
The combination defined in claim 9 and further characterized by each of said arms having a shoulder for abutment with the lateral edge of the plate portion of the opposite leg for limiting the movement of said arms toward each other.
Claim 12
Dependent Claim
39 words
The combination defined in claim 6 and further characterized by each of said plate portions having an opening, and a pivot pin extending through said plate portion openings with its axis normal to the plane of said plate portions.
Claim 13
Dependent Claim
38 words
The combination defined in claim 11 and further characterized by said plate portion opening being of elongated slot-like character and with their axes forming an angle of less than 90° with the longitudinal axis of the related arm.
Claim 14
Dependent Claim
35 words
The combination defined in claim 12 and further characterized by said openings being in axial intersecting relationship when said arms are in closed condition and being in axial parallel relation when said arms are open.
Claim 15
Dependent Claim
39 words
The combination defined in claim 13 and further characterized by said openings having an extent substantially greater than the diameter of the pivot pin whereby the latter moves along said openings during opening and closing movement of said arms.
