Total Claims: 6
Claim 1
Independent Claim
262 words
A wrench for gripping and exerting a turning force upon a generally cylindrical object including: an elongate handle adapted for disposition during use with one end thereof adjacent said object and the remainder thereof extending outwardly from said object in a direction generally radial to the latter, said handle including a main body portion and a gripping lever portion mounted on said body portion and shiftable toward the latter; an elongate relatively flexible strip of sufficient length adapting a distal portion thereof to be wrapped around the circumference of said object and into overlapped relationship upon itself; and means for securing a second portion of said strip to said handle in manner for disposing a stretch of said strip intermediate said portions thereof in a disposition extending from said handle to the proximate extremity of said distal portion in a direction substantially parallel with said radial direction and substantially tangential to the circumference of said object, said second portion of said strip including an extension thereof extending from said stretch thereof between said body and lever portions of said handle, said extension of said strip being secured to said handle when said lever portion is shifted toward said body portion, whereby, upon applying a force to said handle in a direction generally perpendicular to said radial direction, a tension force for tightening said distal portion of said strip upon said object and for turning said object will be transmitted to said proximate extremity of said distal portion through said stretch along a straight path substantially tangent to the circumference of said object.
Claim 2
Dependent Claim
262 words
A wrench for gripping and exerting a turning force upon a generally cylindrical object including: an elongate handle adapted for disposition during use with one end thereof adjacent said object and the remainder thereof extending outwardly from said object in a direction generally radial to the latter, said handle including a main body portion and a gripping lever portion mounted on said body portion and shiftable toward the latter; an elongate relatively flexible strip of sufficient length adapting a distal portion thereof to be wrapped around the circumference of said object and into overlapped relationship upon itself; and means for securing a second portion of said strip to said handle in manner for disposing a stretch of said strip intermediate said portions thereof in a disposition extending from said handle to the proximate extremity of said distal portion in a direction substantially parallel with said radial direction and substantially tangential to the circumference of said object, said second portion of said strip including an extension thereof extending from said stretch thereof between said body and lever portions of said handle, said extension of said strip being secured to said handle when said lever portion is shifted toward said body portion, whereby, upon applying a force to said handle in a direction generally perpendicular to said radial direction, a tension force for tightening said distal portion of said strip upon said object and for turning said object will be transmitted to said proximate extremity of said distal portion through said stretch along a straight path substantially tangent to the circumference of said object.
Claim 3
Dependent Claim
49 words
The invention of claim 1, wherein: said body portion and said lever portion of said handle are provided with opposed surfaces for oppositely gripping said extension of said strip, said surfaces being substantially complemental and defining a sinuous zone in which said extension of said strip may be gripped.
Claim 4
Dependent Claim
66 words
The invention of claim 1, wherein: said extension of said strip includes a terminal portion of greater length than said zone, and said main body portion of said handle is provided with means for storing a selectable part of said terminal portion of said strip internally thereof, whereby the length of said distal portion of said strip may be selectively adjusted to objects of differing circumference.
Claim 5
Dependent Claim
34 words
The invention of claim 1, wherein: said lever portion is provided with marginal flanges extending into overlapping relationship with said main body portion to provide lateral confinement for said extension of said strip therebetween.
Claim 6
Dependent Claim
53 words
The invention of claim 1, wherein there are provided: hinge means swingably interconnecting said lever portion of said handle with said main body portion thereof; and cooperating, interlocking, lost motion means on said main body portion and said lever portion for permitting said movement of said lever portion relative to said body portion.
