US 4,852,874 A · Portable isokinetic exercising device

Abstract

An exercise device comprises an elastic loop having free ends spliced together, generally tubular handles disposed in diametrically opposed relation to one another on the loop and an elastic retainer sleeve surrounding intermediate portions of the loop between the handles. The device is conformable for use in performing a wide variety of exercises and for performing a selected number of repetitions of each exercise by grasping the handles and stretching against the resistance load of the loop and the retainer means. The handles can be grasped either by the hands or by a combination of hands and feet to perform various exercises or may be grasped between the feet or ankle portions to perform other exercises. In modified forms of the invention, one of the handles is made rigid so as to simulate a racquet or golf club handle to be used in practicing forehand and backhand strokes or to simulate the golf swing. The exercises may be performed effectively in either the standing, sitting or fully prone position. Other modified forms of invention include an anchor strap to facilitate practicing of the golf swing and a splice for joining together free ends of the loop into a unitary member.

Dependent claims

An exercise device comprising:

an elastic member in the form of an endless loop;
generally tubular handles disposed on said loop in diametrically opposed relation to one another and in surrounding relation to said loop;
and
retainer means in the form of an elongated protective pliable elastic sleeve surrounding intermediate portions of said endless loop to retain said intermediate portions in closely spaced relation to one another between said handles whereby said retainer means yieldingly resists separation of said intermediate portions of said loop but will not stretch lengthwise in response to grasping of said handles and stretching of said loop between said handles.

An exercise device comprising:

an elastic tubular member in the form of an endless loop having free tubular end portions;
a pair of generally tubular handles disposed on said loop in diametrically opposed relation to one another and in surrounding relation to said loop, at least one of said handles being flexible;
elastic retainer means in the form of an elongated protective elastic pliable sleeve member surrounding intermediate portions of said endless loop, said retainer means being slidable with respect to said intermediate portions between said handles, said retainer means yieldingly resisting separation of said intermediate portions of said loop without lengthwise stretching in response to grasping of said handles and stretching of said loop between said handles;
and
splice means interconnecting said free end portions including a tubular insert oversized with respect to said free end portions, said insert mounted within one of said free end portions, and said insert and said one free end portion being inserted into the other of said free end portions whereby any tension applied to said free end portions causes said free end portions to contract and resist separation from one another.
