Abstract
Abstract A multi-fin aquatic exerciser comprises a main or caudal fin that is strapped to the dorsum of the user's hand or foot. A plurality of secondary fins are attached to the caudal fin and have a spatial configuration that provides significant flow resistance independent of the direction of the user's stroke. The multi-fin exerciser is used in conjunction with specific aquatic exercises providing a complete workout which is especially useful for athletic training, swimming, physical therapy, and shaping, toning, strengthening or enlarging specific muscle groups.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
196 words
In combination in a device for enhanced muscle development by resistive aquatic exercise comprising a fin constructed and configured to fit on the dorsum portion of a user's hand and foot, wherein said fin includes a main fin having an elongated planer shape with a length greater than its width, a curved frontal portion corresponding to the dorsi flexion of the toes during aquatic jogging and made of stiffly flexible material that will substantially retain its shape when subjected to a level of force corresponding to the user's foot movement in an aquatic environment, said fin includes a plurality of secondary fins arranged and configured so that movement of said fin in said aquatic environment is met with a significant level of flow resistance in all directions of movement of the fin in the aquatic environment, said fin further includes a point of flex located substantially perpendicular to the length of said main fin and corresponding to the point of flexure of the user's wrist, said fin further includes a means of attachment to the dorsum portion of the user's hand without substantially interfering with the user's ability to otherwise grasp objects while wearing said fin.
Claim 2
Dependent Claim
196 words
In combination in a device for enhanced muscle development by resistive aquatic exercise comprising a fin constructed and configured to fit on the dorsum portion of a user's hand and foot, wherein said fin includes a main fin having an elongated planer shape with a length greater than its width, a curved frontal portion corresponding to the dorsi flexion of the toes during aquatic jogging and made of stiffly flexible material that will substantially retain its shape when subjected to a level of force corresponding to the user's foot movement in an aquatic environment, said fin includes a plurality of secondary fins arranged and configured so that movement of said fin in said aquatic environment is met with a significant level of flow resistance in all directions of movement of the fin in the aquatic environment, said fin further includes a point of flex located substantially perpendicular to the length of said main fin and corresponding to the point of flexure of the user's wrist, said fin further includes a means of attachment to the dorsum portion of the user's hand without substantially interfering with the user's ability to otherwise grasp objects while wearing said fin.
Claim 3
Dependent Claim
71 words
In combination in the device of claim 1 wherein said plural secondary fins are located on a top side of said main fin and include a dorsal fin and two paired fins wherein said dorsal fin extends substantially perpendicular to said main fin and substantially parallel to the direction of the length of the main fin and said paired fins extend substantially perpendicular to said main fin and said dorsal fin.
Claim 4
Dependent Claim
20 words
In combination in the device of claim 2 wherein said plural secondary fins are more flexible than the main fin.
Claim 5
Dependent Claim
31 words
In combination in the device of claim 2 further comprising a back fin attached to said dorsal fin and extending out therefrom in a direction substantially parallel to said main fin.
Claim 6
Dependent Claim
25 words
In combination in the device of claim 1 wherein said fin is further configured to be capable of attachment to the palm of the hand.
Claim 7
Dependent Claim
38 words
In combination in the device of claim 1 wherein said fin is further configured so that the fin is subjected to different levels of flow resistance in at least three substantial directions of movement in the aquatic environment.
Claim 8
Dependent Claim
195 words
In combination in a device to be attached to a user's hand so that the user can maintain balance while operating in an aquatic environment comprising a fin constructed and configured to fit on the dorsum portion of the user's hand, wherein said fin includes a main fin having an elongated planer shape with a frontal portion curved, a length greater than its width and made of stiffly flexible material that will substantially retain its shape when subjected to a level of force corresponding to the user's foot movement in an aquatic environment, said fin includes a plurality of secondary fins arranged and configured so that movement of said fin in said aquatic environment is met with a significant level of flow resistance in all directions of movement of the fin in the aquatic environment, said fin further includes a point of flex located substantially perpendicular to the length of said main fin and corresponding to the point of flexure of the user's wrist, said fin further includes a means of attachment to the dorsum portion of the user's hand without substantially interfering with the user's ability to otherwise grasp objects while wearing said fin.
Claim 9
Dependent Claim
195 words
In combination in a device to be attached to a user's hand so that the user can maintain balance while operating in an aquatic environment comprising a fin constructed and configured to fit on the dorsum portion of the user's hand, wherein said fin includes a main fin having an elongated planer shape with a frontal portion curved, a length greater than its width and made of stiffly flexible material that will substantially retain its shape when subjected to a level of force corresponding to the user's foot movement in an aquatic environment, said fin includes a plurality of secondary fins arranged and configured so that movement of said fin in said aquatic environment is met with a significant level of flow resistance in all directions of movement of the fin in the aquatic environment, said fin further includes a point of flex located substantially perpendicular to the length of said main fin and corresponding to the point of flexure of the user's wrist, said fin further includes a means of attachment to the dorsum portion of the user's hand without substantially interfering with the user's ability to otherwise grasp objects while wearing said fin.
Claim 10
Dependent Claim
71 words
In combination in the device of claim 7 wherein said plural secondary fins are located on a top side of said main fin and include a dorsal fin and two paired fins wherein said dorsal fin extends substantially perpendicular to said main fin and substantially parallel to the direction of the length of the main fin and said paired fins extend substantially perpendicular to said main fin and said dorsal fin.
Claim 11
Dependent Claim
20 words
In combination in the device of claim 8 wherein said plural secondary fins are more flexible than the main fin.
Claim 12
Dependent Claim
31 words
In combination in the device of claim 8 further comprising a back fin attached to said dorsal fin and extending out therefrom in a direction substantially parallel to said main fin.
Claim 13
Dependent Claim
25 words
In combination in the device of claim 7 wherein said fin is further configured to be capable of attachment to the palm of the hand.
Claim 14
Dependent Claim
37 words
In combination in the device of claim 7 wherein said fin is further configured so that the fin is subjected to different levels of flow resistance in at least three directions of movement in the aquatic environment.
