Pocket-portable hand-strengthening ringlet

Abstract

An inexpensive and durable elastomeric pocket-portable hand-exerciser device for medical-therapeutic or to build-up an athlete's hand-strength. Appearing substantially in the form of an O-ring in axial-view aspect, however preferably offered to buyers in distinct generic-variant configurations;-as a triad-set or quad-set, or individually, each iteration having physically different cross-sections, as follows: A.) presenting vertical elliptical cross-sections in one transverse aspect, and pronated elliptical cross-sections in a 90-degree axially-rotated alternate transverse aspect;-thus being ultimately easy to radially deform by squeezing in the first plane, yet more difficult to radially deform in the alternate radial direction . . . B.) presenting regular circular cross-sections in one transverse aspect, and vertical elliptical cross-sections in a 90-degree axially-rotated alternate transverse aspect; -thus being ultimately difficult to radially deform by squeezing in the first plane, yet less difficult to radially deform in the alternate radial direction . . . C.) presenting regular circular cross-sections in one transverse aspect, and pronated elliptical cross-sections in a 90-degree axially-rotated alternate transverse aspect;-thus being ultimately difficult to radially deform by squeezing in the first plane, yet ultimately easy to radially deform in the alternate radial direction . . . D.) presenting a regular circular cross-sections in one transverse aspect, and like regular circular cross-sections in a 90-degree axially-rotated alternate transverse aspect;-thus being ultimately difficult to go radially deform by squeezing in both radial directions. Hence, these cross-sectionally diverse combinations thus being uniquely configured as to provide the user with variable degrees of hand-squeezing dexterity, calculated to build-up one's hand-strength both as to ultimate squeezing power, and as to ability in sustaining a maximum number of repetitions.

Description

[0001] 1. Field of Invention[0002] This invention relates to pocket-portable palm-sized hand-exercising or hand-strengthening grip-building devices, and more specifically it relates to such devices made of a rubber like elastomer as to be compressively deformable with a resilient memory.[0003] 2. Relevant Prior Art[0004] Background research discovery provides some prior patent-art regarded as germane to this disclosure;--chronologically for example U.S. Pat. No. 3,265,389(filed: July 1963) shows a palm-sized primarily physically therapeutic (said to be mentally tranquilizing also) hand-exerciser device made of solid molded rubber construction, and is described as a planar oblong shape with an integrally molded rubber bar bisecting it lengthwise. Although is it designed to be squeezeably deformed, none of configuration is circular or of elliptical cross-section.[0005] In U.S. Pat. No. 3,612,521(filed: October 1971) is shown a a one-piece molded rubber device having five digit-holes (...

AI Technical Summary

Problems solved by technology

Thus is deemed unsuitable for continued manipulation in the hand, and is not small enough to be pocket-portable.

However, the overall configuration is not circular, nor does it employ elliptical cross-sectioning.

However, the rings are rigid, thus not in of themselves resilient...
