Abstract
Abstract A handle structure attached to the free end of a towline or rope to enable the same to be releasably gripped and held conveniently. The handle structure is especially useful for water skiing, and it functions to augment or enhance the natural grip of the skier yet enables him to quickly release his grip when necessary. The extent to which the grip of the skier is enhanced by the handle structure is selectively variable to permit the structure to be adjusted to the requirements of any particular skier. The handle structure may be in the form of a single unit sufficiently large to be gripped by both hands, and in this form it includes a handhold component adapted to be gripped by each hand of the skier. A compression member movable with respect to the hand hold component and urged theretoward into compressive engagement with the fingers of a hand compressively grips the same whenever a tensile force is applied to the towline. Adjustable limit structure carried by the compression member and provided with a plurality of elements of differing dimensions that are selectively positionable intermediate the compression member and handhold component is effective to limit relative movement therebetween in directions toward each other so as to establish a predetermined spacing therebetween to tailor the grip-enhancing feature to the skiers requirements.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
199 words
A handle structure for a water ski towline and the like, comprising: a handhold component adapted to be grasped by the hand of one using the same; a compression member extendible along said handhold component and substantially parallel therewith for movement with respect thereto between a closed position in proximity therewith to bear against the fingers of one gripping said handhold component and release position spaced therefrom to enable the same to be gripped; fastener means provided by said compression member for securing a towline thereto so that a force can be transferred from the towline to the compression member; guide means provided by said handhold component for passing such towline therethrough while effectively reversing the direction thereof and affording relative movement therebetween so that a tensile force applied to such towline by a boat pulling the same will cause said compression member to be urged toward said handhold component and compressive engagement with the fingers of a hand gripping the same; and adjustable limit structure having a plurality of sections of differing dimensions selectively positionable intermediate said compression member and handhold component to limit relative movement therebetween in directions toward each other and thereby establish predetermined spacings therebetween.
Claim 2
Dependent Claim
199 words
A handle structure for a water ski towline and the like, comprising: a handhold component adapted to be grasped by the hand of one using the same; a compression member extendible along said handhold component and substantially parallel therewith for movement with respect thereto between a closed position in proximity therewith to bear against the fingers of one gripping said handhold component and release position spaced therefrom to enable the same to be gripped; fastener means provided by said compression member for securing a towline thereto so that a force can be transferred from the towline to the compression member; guide means provided by said handhold component for passing such towline therethrough while effectively reversing the direction thereof and affording relative movement therebetween so that a tensile force applied to such towline by a boat pulling the same will cause said compression member to be urged toward said handhold component and compressive engagement with the fingers of a hand gripping the same; and adjustable limit structure having a plurality of sections of differing dimensions selectively positionable intermediate said compression member and handhold component to limit relative movement therebetween in directions toward each other and thereby establish predetermined spacings therebetween.
Claim 3
Dependent Claim
42 words
The handle structure of claim 1 in which said limit structure is carried by one of said compression member and handhold component for movement relative thereto to effect the aforesaid selective positioning of said sections intermediate said compression member and handhold component.
Claim 4
Dependent Claim
53 words
The handle structure of claim 2 in which said limit structure is carried by said compression member for angular displacements relative thereto and is annular and subdivided into a plurality of arcs each of which has a radius varying from that of the others and respectively defining the aforesaid sections of differing dimensions.
Claim 5
Dependent Claim
25 words
The handle structure of claim 3 in which said limit structure is equipped with a plurality of angularly spaced stops respectively interposed intermediate said arcs.
Claim 6
Dependent Claim
56 words
The handle structure of claim 2 in which said limit structure is annular and angularly displaceable with respect to the member carrying the same, and in which said limit structure includes a pluralIty of arcs each of which has a radius varying from that of the others and respectively defining the aforesaid sections of differing dimensions.
Claim 7
Dependent Claim
25 words
The handle structure of claim 5 in which said limit structure is equipped with a plurality of angularly spaced stops respectively interposed intermediate said arcs.
Claim 8
Dependent Claim
36 words
The handle structure of claim 6 in which a pair of limit structures are disposed in axially spaced relation along said handle structure each being equipped with a plurality of arcs of varying radii as aforesaid.
Claim 9
Dependent Claim
117 words
The handle structure of claim 1 in which said compression member and handhold component are axially elongated and said compression member includes an elongated core and a sleeve rotatably supported thereon in a coaxial circumjacent relation therewith, said sleeve being segmented and providing independently rotatable sections adapted to respectively engage hands and fingers of one using the handle structure; a pair of limit structures are mounted upon one of said compression member and handhold component in axially spaced relation therealong for abutable engagement with the other, each of said limit structures having a plurality of arcs each of which has a radius varying from that of the others and respectively defining the aforesaid sections of differing dimensions.
Claim 10
Dependent Claim
27 words
The handle structure of claim 8 in which each of said limit structures is equipped with a plurality of angularly spaced stops respectively interposed intermediate said arcs.
