Abstract
Abstract A spring whip is formed of plural lengths of helically wound springs having respectively smaller diameters permitting them to be interconnected about a common axis. The springs are movable between a telescoped storage position, and an extended operative position. A hollow housing is provided both as a hand grip as well as a storage housing for the springs in a telescoped position. A magnet is located in the top of the housing and restrains the springs in their telescoped storage position. A weighted tip is formed at the distal end of the smallest diameter spring for aiding in the projection of the springs into their extended position, and simultaneously forming a closure for the housing when the springs are in their storage position.

Claim 1
Independent Claim
353 words
A spring whip comprising a hollow housing serving as a hand grip and providing an internal storage compartment, plural lengths of helically wound springs, said springs being of selected diameter sizes ranging from a small diameter spring to a large diameter spring, said springs being operatively arranged relative to each other about a common axis so as to be movable between a telescoped storage position within said storage compartment and an extended whipping position extending from a first end of said hollow housing, said springs including engaging means for interconnection of telescoped ends of said springs in said extended whipping position, retaining means coupled to said hollow housing for normally retaining said springs in said telescoped storage position, said retaining means including a magnet positioned at an opposite second end of said hollow housing, said springs being fabricated from a magnetic attracting material, cap means for closing said second end of said hollow housing, said cap means including a head portion and a tubular body portion connected thereto, said head portion having a larger cross-section facing in a longitudinal direction of said hollow housing than said tubular body portion, said magnet being retained within said tubular body portion, said tubular body portion extending into said second end of said hollow housing, said cap means further including a conical neck portion interconnecting said head and tubular body portions, said neck portion having a smaller cross-section facing in said longitudinal direction than said tubular body portion to provide a recess, an edge of said second end of said hollow housing being crimped into said recess against said neck portion to retain said tubular body portion within said hollow housing, a weighted tip being coupled to a distal end of said small diameter spring to aid in projecting said springs into said extended whipping position where said weighted tip overcomes attraction of said magnet, and each of said springs having an end surface facing said magnet for contact therewith, each said spring end surface being flat to provide uniform abutment against said magnet for sufficient attraction therebetween when said springs are in said telescoped storage position.

A spring whip comprising a hollow housing serving as a hand grip and providing an internal storage compartment, plural lengths of helically wound springs, said springs being of selected diameter sizes ranging from a small diameter spring to a large diameter spring, said springs being operatively arranged relative to each other about a common axis so as to be movable between a telescoped storage position within said storage compartment and an extended whipping position extending from a first end of said hollow housing, said springs including engaging means for interconnection of telescoped ends of said springs in said extended whipping position, retaining means coupled to said hollow housing for normally retaining said springs in said telescoped storage position, said retaining means including a magnet positioned at an opposite second end of said hollow housing, said springs being fabricated from a magnetic attracting material, cap means for closing said second end of said hollow housing, said cap means including a head portion and a tubular body portion connected thereto, said head portion having a larger cross-section facing in a longitudinal direction of said hollow housing than said tubular body portion, said magnet being retained within said tubular body portion, said tubular body portion extending into said second end of said hollow housing, said cap means further including a conical neck portion interconnecting said head and tubular body portions, said neck portion having a smaller cross-section facing in said longitudinal direction than said tubular body portion to provide a recess, an edge of said second end of said hollow housing being crimped into said recess against said neck portion to retain said tubular body portion within said hollow housing, a weighted tip being coupled to a distal end of said small diameter spring to aid in projecting said springs into said extended whipping position where said weighted tip overcomes attraction of said magnet, and each of said springs having an end surface facing said magnet for contact therewith, each said spring end surface being flat to provide uniform abutment against said magnet for sufficient attraction therebetween when said springs are in said telescoped storage position.
Claim 3
Dependent Claim
69 words
A spring whip as in claim 1, wherein an outermost end of said tip is of a size substantially equal to an opening in said first end of said hollow housing to close said opening when said springs are in said telescoped storage position, and a circular seat provided in said tip at an opposite end thereof for receiving and retaining said distal end of said small diameter spring.
Claim 4
Dependent Claim
43 words
A spring whip as in claim 1, wherein said engaging means include said telescoped ends of adjacent telescoped pairs of springs being of cooperating progressively diminishing diameters for wedging engagement therebetween at termination of movement of said springs into said extended whipping position.
Claim 5
Dependent Claim
21 words
A spring whip as in claim 3, wherein said telescoped ends are coated with a Teflon material to allow unlocking therebetween.
Claim 6
Dependent Claim
68 words
A spring whip as in claim 1, wherein said hollow housing is provided with a conical lip defining an exit opening of a progressively diminishing extent, said large diameter spring including an end of progressively increasing diameter, said end of said large diameter spring and said conical lip cooperating together to provide a wedging engagement therebetween at termination of movement of said springs into said extended whipping position.
Claim 7
Dependent Claim
25 words
A spring whip as in claim 5, wherein said end of said large diameter spring is coated with a Teflon material to allow unlocking thereof.
Claim 8
Dependent Claim
242 words
A spring whip comprising a hollow housing serving as a hand grip and providing an internal storage compartment, plural lengths of helically wound springs, said springs being of selected diameter sizes ranging from a small diameter spring to a large diameter spring, said springs being operatively arranged relative to each other about a common axis so as to be movable between a telescoped storage position within said storage compartment and an extended whipping position extending from a first end of said hollow housing, said springs including engaging means for interconnection of telescoped ends of said springs in said extended whipping position, retaining means coupled to said hollow housing for normally retaining said springs in said telescoped storage position, said retaining means including a magnet positioned at an opposite second end of said hollow housing, said springs being fabricated from a magnetic attracting material, cap means for closing said second end of said hollow housing, said cap means including a head portion and a tubular body portion connected thereto, said magnet being retained within said tubular body portion, said tubular body portion extending into said second end of said hollow housing, said magnet being fit tightly within said tubular body portion, an air space being provided between said magnet and said head portion, and a radial air hole being provided in said tubular body portion and communicating with said air space to permit said magnet to be positioned into said tubular body portion.
