Abstract
A hand exerciser device, comprised of a body having a thumb opening, a plurality of finger openings spaced apart from the thumb opening, and a central enlarged portion interposed between the thumb opening and the finger openings where the body is fabricated from a gelatinous elastomeric composition having both sufficient stretchability for extension of the hand exerciser device by opposing pressures applied by the thumb and at least one finger and sufficient resistance for compression of the hand exerciser device by cooperating pressures applied by the thumb and at least one finger and also returning to the original shape with release of the pressures, even after extensive repeated extending and/or flexing.
Claims17
A hand exerciser device, comprising:
- a body having a thumb opening, a plurality of finger openings spaced from said thumb opening, and a central enlarged portion interposed between said thumb opening and said finger openings,
- wherein said body being fabricated from a polymeric material having both sufficient stretchability for extension of said hand exerciser device by opposing pressures applied by a thumb and at least one finger and sufficient compressibility for compression/flexion of said hand exerciser device by cooperating pressures applied by the thumb and at least one finger and also returning to the original shape with release of said pressures, even after extensive repeated extending and/or flexing.
A hand exerciser device, comprising:
- a body having a thumb opening, a plurality of finger openings spaced from said thumb opening, a central enlarged portion interposed between said thumb opening and said finger openings, and a core disposed in said central enlarged portion;
- wherein said body being fabricated from a polymeric material having both sufficient stretchability for extension of said hand exerciser device by opposing pressures applied by the thumb and at least one finger and sufficient compressibility for compression/flexion of said hand exerciser device by cooperating pressures applied by the thumb and at least one finger and also returning to the original shape with release of said pressures, even after extensive repeated extending and/or flexing;
- said polymeric material being a gelatinous elastomeric composition being a mixture of at least one styrenic block copolymer selected from the group comprising:
- SBS (styrene butadiene styrene), SIS (styrene-isoprene-styrene), SEPS (styrene ethylene/propylene styrene), SEBS (styrene ethylene/butylene styrene), SEEPS (styrene ethylene/ethylene-propylene-styrene);
- and at least one oil (or plasticizer) being selected from the group comprising:
- a mineral oil, a silicone oil, a vegetable oil, or a fish oil;
- said thumb opening and said finger openings providing sufficient grip on a users thumb and fingers as to prevent accidental release and dropping of said hand exerciser device;
- said hand exerciser device having a Shore OO durometer of between 6 and 30 and a durability to sustain at least 400,000 extensions and/or compressions.
