1,945,134 [/1934 Brunk 272/82 7 Claims, 4 Drawing Figures Patented July 24, 1973 HAND EXERCISER BACKGROUND OF THE INVENTION Over the years there have been a variety of tension type exercising devices which have been utilized by the hands and legs. Most of these devices have incorporated coiled metal springs in varying arrangements. The primary disadvantage with metal springs is that they cannot contact the user during extension due to the pinching caused thereby. The present invention utilizes elastic cords, commonly called bungee cords, which are made up of hundreds of small rubber bands surrounded by a fabric sleeve. Due to the particular spacing of the elastic cords at their juncture with the smaller hand grip member, they provide a secondary function as a massaging means. When the smaller handle is gripped with one finger extending between the pair of elastic cords, the action of the cords on the hand between the knuckles provides a stimulating massage par ticularly useful with arthritic joints.

It is therefore the principal object of the present invention to provide a combined exercising and massaging device with a multiplicity of uses.

Another object of the present invention is to provide an exercising device useful in various isometric exercises.

A further object of the present invention is to provide a safe and inexpensive therapeutic exercising device for use by arthritics, those recovering from broken bones and other surgery cases requiring muscle exercise and massage.

FIG. 1 is a perspetive view of the exerciser with the hands of the user illustrating one method of use;

FIG. 2 is a plan view of the exerciser with portions of one hand grip broken away for detail;

FIG. 3 is an enlarged sectional view taken along lines 3 3 of FIG. 2; and

FIG. 4 is a modified form of the smaller hand grip member.

Referring now to the drawings and more specifically to FIG. I, the hand exercising device is generally identified by reference numeral 10. The exerciser is made up of a pair of round

hand grip members

16 and 18, joined by a pair of elastic cords 20 of equal length. While a variety of elastic cords could be used, the cord 20 illustrated in the drawings is a bungee type cord having a core of rubber bands surrounded by a woven fabric sheath 20', as seen in detail in FIG. 3. The larger hand grip member 18 is made up ofa rigid tubular material 22, such as plastic or metal having a pair of lateral holes 30 approximate the ends thereof for receipt of the elastic cord 20. Surrounding the tubular member 22 is a second sleeve of spongy material 24 which readily depresses when gripped by the hand of the user. Located in the ends of the tubular member 22 are a pair of plugs 26 which close the ends of the handle member 18 once the cords 20 are in place. To hold the elastic cord 20 in place in the handle, the end of the cord is doubled back and a wire bale 28 is wrapped around a double portion of the elastic cord which has sufficient size so as not to fit through the hole 30 in the tube 24. The smaller hand grip member 16 is similar in construction to hand grip 18 with the exception that the cords 20 are more closely spaced together a dis tance A, as illustrated in FIG. 2. This distance A is approximately the width of a single finger so that the cords 20 are in alignmentwith the valleys between the fingers, as seen in FIG. 1.

FIG. 4 illustrates a modified form of the smaller hand grip 16 whereby the holes 30A are slot-shaped, extending longitudinally of the handle 16. The slots 30A allow the cords 20 to be moved longitudinally within the hand grip 16 so as to vary the distance A therebetween. This variable spacing has particular utility with users having varying sized hands. While the longer dimension of the slot 30A is greaterthan the diameter of the wire bale 28, the lesser dimension of slot 30A is lesser than the diameter of bale 28 so that the cord 20 is still held in the handle member 16.

OPERATION While the exercising device of the present invention has a variety of combination arm and leg stretching exercises, its primary useage is illustrated by the hand positions in FIG. 1. The elastic cords 20 attached to the smaller hand grip portion 16 pass through the valleys of hand 14 surrounding the knuckle of the middle finger. To exercise the various muscles in both arms and wrists, the

hand grip members

16 and 18 are pulled apart, held, and then brought together again. If it is desired to exercise the wrist only, the cords 20 are stretched by merely rotating the right wrist. The secondary function of the cords 20 is a massaging action which takes place on both sides of the main knuckle of the center finger in right hand 14. With the cords 20 in a tension position, the wrist rotation of right hand 14 effects a massaging action to the back of the right hand approximate whatever knuckle joint is surrounded. This massaging action is very beneficial to an arthritic joint aside from being a mere extension exercise. The smaller hand grip 16 can be gripped in any manner so that any of the five fingers is placed between the elastic cords 20, including the thumb. The FIG. 4 embodiment allows a person having a substantially larger hand to adjust the spacing of the cords 20 to fit that particular hand.

Having described the invention with sufficient clarity to enable those familiar with this art to construct and use its general principles, I claim:

1. A therapeutic hand exercising; device comprising:

a first hand grip member havinga pair of lateral openings therein approximate the ends thereof spaced apart a longitudinal distance approximate the width of a users hand; I

a second hand grip member havinga pair of lateral openings therein longitudinally spaced apart a distance approximate the width of the users finger;

a pair of elastic cords connecting the two pairs of openings; and

fastening means holding the ends of the elastic cords in the hand grip members whereby the hand grip members can be gripped in opposite hands and moved apart in parallel spaced relation against the resistance of the elastic cords.

2. A therapeutic hand exercising device as set forth in claim 1, wherein the pair of openings in the second hand grip member are longitudinal slots which allow the elastic cords to be moved in the slots to vary the space between the cords.

3. A therapeutic hand exercising device as set forth in claim .1, wherein the second hand grip has a length approximate the width of the users hand and the latera] openings are equally spaced inwardly from the ends thereof.

4. A therapeutic hand exercising device as set forth in claim 1, wherein the hand grip members have a rigid tubular core and a layer of soft resilient material surrounding the core and the fastening means is a wire bale which doubles back and surrounds the end of the elastic cord.

5. A therapeutic hand exercising device as set forth in claim 1, wherein the hand grip members have a rigid tubular core and a layer of soft resilient material surrounding the core and the fastening means is a wire bale which doubles back and surrounds the end of the elastic cord made up of a group of rubber bands surrounded by a fabric cover.

6. A therapeutic hand exercising device as set forth in claim 1, wherein the fastening means is a wire bale which is bent around a doubled portion of the elastic cords.

7. A therapeutic hand exercising device as set forth in claim 1, wherein the pair of openings in the second hand grip member are longitudinal slots having a width equal to the diameter of the elastic cord and a length approximately twice said diameter, and the fastening means doubles back and surrounds the end of the elastic cord doubling its size.

Claims

A therapeutic hand exercising device comprising: a first hand grip member having a pair of lateral openings therein approximate the ends thereof spaced apart a longitudinal distance approximate the width of a user''s hand; a second hand grip member having a pair of lateral openings therein longitudinally spaced apart a distance approximate the width of the user''s finger; a pair of elastic cords connecting the two pairs of openings; and fastening means holding the ends of the elastic cords in the hand grip members whereby the hand grip members can be gripped in opposite hands and moved apart in parallel spaced relation against the resistance of the elastic cords.

3. A therapeutic hand exercising device as set forth in claim 1, wherein the second hand grip has a length approximate the width of the user''s hand and the lateral openings are equally spaced inwardly from the ends thereof.
