Abstract:
Left and right hand exercisers are formed based upon a modification of the handgrips disclosed and claimed in U.S. Pat. No. 5,979,015, wherein a throughbore is made through the grip, generally vertically through the elongation of the grip, at an angle between 82 and 88 degrees. A flattened tube of nylon webbing, or equal, is disposed through the throughbore, and is either connected to itself to form an endless loop spaced from the body of the grip in one embodiment. In another embodiment, the webbing passing through the bottom end of the grip is retained in place by one of several means. The end of the webbing emanating from the top of the grip may be attached directly to an elastic tube or band, or to a swivel split ring. If the latter, cables or other devices can be appended to the split ring as is known to the art.

Description:
RELATION TO OTHER PATENTS AND PATENT APPLICATIONS. 
     Applicant is the inventor of U.S. Pat. No. 5,979,015, issued Nov. 9, 1999, the disclosure of which patent is incorporated herein by reference. 
    
    
     FIELD OF THE INVENTION 
     This invention pertains to two embodiments of a handheld exerciser, both of which embodiments employ the grips of U.S. Pat. No. 5,979,015. 
     BACKGROUND OF THE INVENTION 
     It is well known that the majority of the muscles of the body are intended to operate on a linear direction when moved, or exertion takes place. If the skeletal frame is misaligned when muscle action transpires, the body is readily displaced. Should one of either the shoulder or hips become displaced during musculature activity, the displacement of either of these two key elements of the body will also appear to have been stressed. 
     Not only in reaching and grabbing motions, but in exercise activities is it important to keep the body and its parts from getting into unstable positions. Thus I have now extended the use of my grips invention into becoming hand-held exercisers which when help properly and used as described herein, will result in the proper use of the biceps, the triceps, and the abdominal muscles. 
     By incorporating the resistance tubing or resistance bands one can utilize this invention to carry out triceps and lat pull downs, crunches and biceps curls among other exercises, all while maintaining proper upper body positioning. 
     It is important for the reader to understand that the grips have a left hand unit and a right hand unit. The grip for one hand is not interchangeable for use by the opposite hand. If a person were to spread out their left hand in front of a mirror, the virtual image seen would be the right hand. In the same manner, the left grip is a mirror image of the right grip. Just as a left hand leather glove does not properly fit the right hand, so too with the original grips, and the grips as modified to form this invention. One must use the right hand handgrip in the right hand, and the left hand grip in the left hand. 
     As used herein the term right hand exerciser means a grip for the right hand of a person, modified to be used in this invention. Since these exercisers are used by the hands as opposed to the feet, they are referred to as hand exercisers. Thus, we have left hand and right hand exercisers in this invention. 
     SUMMARY OF THE INVENTION 
     This invention pertains to hand-held exercise equipment based upon the grips of U.S. Pat. No. 5,979,015 which grips have been bored through and have a flexible band of webbing disposed therethrough. The flexible webbing band can traverse one of several paths. It can be tied off at the bottom of a first grip and be connected to one end of the length of an elastic band or ribbon; or connected to one end of the length of flexible elastic tubing. In such instances the grip used by the second hand would be fashioned in a like manner to the opposite end of the flexible elastic band or ribbon or to the second end of the length of flexible elastic tubing. The variant of this first embodiment has a split ring tied into position of the flexible elastic band or ribbon, or even of flexible tubing at about the midpoint thereof. Other cables, ropes or ribbons can be attached to the split ring for the specific exercise desired. In the second embodiment, the flexible webbing band or ribbon passes through the grip and loops back to itself in an endless loop.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     For convenience, in order to better understand the exercisers of this invention, a short discussion of the patented grip  10  utilized in this invention will be described as shown in FIG. 1 extending generally upright, although its orientation might vary for different exercises. 
     More particularly, as shown best in FIGS. 1A,  1 D, and  12 , the illustrated grip  10  is formed at a first or upper end  14  with a thumb support  18  that includes a generally upwardly facing thumb support surface or ledge  20 . That surface  20  extends outwardly to one side of the base  12  and slightly downwardly; the surface  20  helps locate and support the thumb of the user extending generally forwardly and to the side, with the thumb bent and the end digit inclined somewhat downwardly. The thumb support  18  also includes a generally upstanding locating surface  22  that extends generally transversely to the support surface  20  at the forward/sideward direction or angle noted above. The locating surface  22  engages the side of the gripping thumb. Surfaces  20  and  22  combine to locate and maintain the gripping thumb in the desired comfortable angled and bent position. 
     FIG. 12 shows a hand wrapped around the grip  10  as viewed from the left; the hand is not significantly tilted either toward the thumb or the little finger. Thus the hand and wrist are in a generally neutral position when the hand grasps the grip  10 . 
     As shown best in FIGS. 1B,  1 C, and  12 , the illustrated grip  10  has a generally forwardly facing front edge portion  24  having individual indentations or grooves  26  each accommodating one of the fingers of the gripping hand. This forward edge portion  24  generally engages so as to position and support the first joint (close to the palm) of each of the side fingers. This in turn tends to determine the alignment of the knuckles and facilitates aligning those knuckles in a generally straight line as viewed from the back of the hand. 
     In particular, there is a slight depression  30  in the surface  28  to accommodate the portion of the palm adjacent to and just forwardly of the thumb. 
     The side surface  32  of the grip  10  between the forward and rearward edge portions  24 ,  28 , which engages the palm of the hand adjacent to the fingers, is suitably contoured and selectively recessed to comfortably receive the joints between the fingers and the bones of the hand and to allow the grip to be squeezed without misalignment of the knuckles as discussed above. In particular, there is a specific upper recess or depression  34  to accommodate the joint between the first finger and the second metacarpal of the hand. Further, the side palm engaging surface  34  has a lower recess  36  to accommodate the heel of the hand, i.e., the joint between the little finger and the adjacent metacarpal. This last accommodation is particularly significant as it contributes and facilitates the extended or increased contraction of the little finger relative to the other fingers as described above. In this connection, at the forwardly facing front end portion  24  of the grip, the lowermost groove  26 A for the little finger is enlarged to facilitate the additional contraction. 
     The opposite side surface  38  of the grip  10  is generally flat as shown in FIGS. 1A, and  1 D. That surface  38  extends in a generally upright plane that is at a light sideward angle from the forwardly facing edge portion  24 , to provide a comfortable positioning and resting stop for the ends of the gripping fingers. In this connection, the underside of the thumb support  18  is formed with a smooth angled undersurface  40  to provide a comfortable support and resting place for the end of the first finger of the gripping hand. This surface extends rearwardly at a slight outward angle outwardly from the forwardly facing edge portion  24 . 
     The lower end  16  of the grip  10  is provided with an enlarged end portion  42  which serves as a guide and limit stop for the hand when it reaches for and engages the grip. 
     While the grip  10  as modified for use in this invention will accommodate some variation in hand size, the size of the grip may be varied to fit different sized hands, particularly for women and children with normally smaller hands. 
     The grip  10  shown in FIGS. 1A-1D have been modified from the grip shown in the aforementioned U.S. Pat. No. 5,979,015, to suit the purposes of this invention. Thus, the grip  10  seen here has a throughbore  19  which extends through the full length of the grip  10  from upper opposed end  14  through the bottom opposed end  16 . Location  15  indicates the spot where a metal ring or other retainer may be placed or a knot tied at the lower end of the grip  10 . Bore  19 , as per FIG. 9, is seen to be made at an angle of about 83 degrees to the horizontal. The angle may vary ±3 degrees and still work acceptably. Shown in FIG. 1A is flattened tubular webbing  17 , preferably made of nylon. Such material is readily available in the marketplace from such companies as REI and is sold under the brand name Blue Water. This flattened webbing is primarily used by climbers. 
     FIG. 2 also illustrates that webbing  17  passes through the bore  19  in the upper opposed end  14  of the grip  10 . 
     FIG. 3 is the opposite or lower end  16  of the left-handed handgrip. Location  15  is at the end of bore  19  and signifies the location where a knot, metal ring or other member may be placed for retention. 
     In FIG. 4, the first embodiment of the invention  11  is seen. Here grip  10  has a webbing section  17  passing through the full length of the grip of throughbore  19 . While the webbing is one continuous piece  17 , it will be discussed in segments for ease and understanding, and ready reference to the figures. Thus, segment  17 A seen emanating from the upper end  14  of the grip passes through one of two slots  45  in retainer member  44 . The retainer member, which is seen here is rectangular in configuration, is divided in half by divider  46 , in one direction. There is no directional orientation to this retainer member. 
     The other segment  17 B passes from the bore  19  at the lower end  16  of grip  10  through the second slot in retainer member  41 . A finite length of flexible tubing  18  has one of its terminii folded into a U and retained in position by webbing  17 . The retainer member&#39;s divider  46 , preferably has teeth facing one way to grab and retain the webbing passing through each of the two slots as shown. Upon being held in the retainer member, the webbing is seen to have formed an interrupted endless loop through the grip and the retainer member. In FIG. 4, only one terminus of the tubing  18  is shown knotted and retained by webbing  17 . The second terminus of the elastic tube (preferably of latex)  18  is retained in the same manner by the second grip. Neither the second grip nor the second end of the flexible tubing  18  are seen in FIG.  4 . This loop of tubing through the webbing contains between 6 and 8 inches of tubing such that the loop formed is spaced from the body of the grip  10  and therefore does not lie on the hand during usage. The entire length of tubing utilized is between 22 and 28 inches in length. 
     FIG. 5 is a closeup of the retention of webbing  18 . Here both slots  45  are seen as is the divider  46 . There is no rocket science to the knot made between the webbing and the tubing. Any conventional knot will suffice for this purpose. 
     FIG. 6 is a right rear perspective view of the grip  10  webbing  17  seen in a front perspective view in FIG. 7, no further discussion of this view is required. 
     FIG. 7 is a perspective view of the left side of both of the left grip and the right grip, both of which are connected to a finite length of flexible tubing. Discussion supra. 
     In FIGS. 8A and 8B the two grips for the left hand and right hand are both seen and designated  10 R and  10 L, respectively. Each of them forms part of the second embodiment  51  of this invention. In this embodiment, webbing  18  passes though bore  19 , tied into a knot, and the now endless looped webbing  18  has its knot forced up into bore  19  primarily for aesthetics. Webbing  18  is strong and flexible but not elastic in nature. In the alternative, the two ends of the webbing may be fused or adhesed and then forced into throughbore  19 . 
     It is seen that webbing  51  passes through bore  19  of each of the handgrips, as is seen in FIG. 3 et seq. The two ends of the webbing may be secured to each other as is discussed herein, per FIG. 8, or the two ends can be used separately as is shown in FIG.  4 . In FIG. 4 they are tied in a sailor&#39;s knot. 
     In FIG. 9, the angle of passage of the webbing as it would pass through bore  19  is illustrated. The angle is seen to be 83 degrees, ±3 degrees. This range is specified as it is often difficult to machine a multi-surface complex rubber unit in repetitive fashion to close tolerances. It has been found that when the bore is between 82 and 88 degrees from the vertical that excellent results are obtained when the piece of equipment is used by persons in the field for exercise purposes. 
     In FIG. 10, the third embodiment of this invention is seen. One end of the webbing of a finite length usually from 12 to 18 inches passes through the left grip via the throughbore (not seen) and retained at the lower end thereof by a chrome ring  53  through which the webbing&#39;s terminus is looped through and stitched back to the rest of the length of webbing, thereby forming a loop over the ring. 
     The length of webbing  18  exits at the upper end  14  of the first grip  10 L and is looped around and through ring  64  to secure one to the other. Any conventional knot can be employed. 
     The lower ring  64  is attached to and rotates around swivel pin  65  of the swivel split ring  63 . This swivel split ring  63  includes a broad arcuate segment  66  and a pivot jaw  67 . Such swivel split rings  63  are readily available in the marketplace from several manufacturers. Typically, hardware stores carry them. 
     Once looped around and over lower ring  64 , the webbing segment passes downwardly through the right grip  10 R and is secured in place at the lower end  16  by a retainer designated  62 . Here webbing  18  is looped through the retainer, held by the teeth of the retainer and passed through the retainer again, in a manner similar to FIG.  5 . In the alternative, the webbing segment can be sewn back over itself for retention in the same manner as was done with the left grip using a second ring  53 . Thus two distinct methods maybe employed to retain the end of the webbing segment or webbing section at the lower opposed end of the grip. 
     The fixed arcuate segment  66  can be attached to various things, such as flexible tubing among other items or directly to a connection on a wall or ceiling. This is an excellent piece of equipment for the strengthening of the arm muscles. 
     FIG. 11 shows a person  100  who has placed the tubing of the second embodiment beneath his foot, under the shoe, and within his fist  10 R. He could hold one of the grips  51 , though not shown, in a fixed position while tugging on the second grip to carry out a one-armed biceps curl. Or, a second same piece of equipment shown in the left hand could be employed simultaneously in the right hand as may be desired. 
     FIG. 12 shows the correct position for holding the grip during exercises. The handgrip shown applies to any embodiment of the grip, and is independent of whether tubing or webbing passes through the grip. In this figure, elastic tubing  55  is passed through bore  19 , as is within the scope of the invention. Such tubing can be tied off to form an endless loop in the manner shown in FIG.  8 B. The loop could be placed over a doorknob, or over a horizontal rod and then stretched by the movement of the arm to overcome the resistance. Other exercises are within the skill of those who operate in the field of exercise training. 
     FIG. 13 illustrates the grip shown in FIG. 1 but to which a minor modification has been made. An upstanding section  27  has been added at the upper opposed end, which upstanding section has a central bore in aligned communication with throughbore  19  such that the entire bore is still designated  19 . The purpose of this upstanding section is to keep the webbing or tubing passing therethrough away from the hand. 
     FIG. 14 is similar to FIG. 13, but instead of modifying the grip, an adapter  20  having a downwardly depending cylindrical insert section  21  to retain the adapter in position by friction fit through bore  19  is shown. The adapter  20  may be made of plastic or metal such as aluminum, or even hard rubber. The adapter  20  serves the same purpose as the upstanding section shown in previous FIG.  13 . It is also to be seen that carbon fibers may be employed for structural support in the construction of adaptor  20 . A tightener  62  is also shown in FIG.  14 . Such may be employed to retain the webbing, such that a glued terminus folded back becomes unnecessary. The tightener  62  serves to prevent slippage. See FIG. 10 for its use as well. The tightener is used in conventional manner by placing the first end of the webbing down through the first slot and up through the second slot, as if one were tightening a fanny pack strap. Further discussion is deemed unnecessary since the operation would be somewhat similar to that illustrated in FIG. 4 for the use of retainer ring  44 . 
     As to the third embodiment previously discussed, the swivel split ring  62  can be connected to any cable resistence system, such as Pilates, or the Total Gym system, both of which products are readily available in the marketplace. When so attached, the user has the ability to indicate greater activity in the arms by exercising the biceps, triceps, and deltoid muscles as well as the pectorals of the chest among others. 
     It is also to be understood that the first and the third embodiments of the invention can also be employed for physical therapy purposes for those who suffer from reduced use of an arm. 
     As to the second embodiment of the invention wherein the webbing forms a continuous loop through the grip per FIG. 8, they are utilized in the following manner: 
     The unit is attached to a Total Gym® or Bowflex®, apparatus with a spring clip. Then the user can do arm curls, rows, or crossovers; basically all the same movements as one would do without the improvement of this invention. The addition of this invention provides better muscle improvement, and reduction of pressure on the shoulders and upper back. 
     The reader is reminded that the ergonomic hand exercisers of this invention each have a left hand model for use in the left hand and a right hand model for use in the right hand, when the finite section of webbing or tubing&#39;s end are connected to form an endless loop, the one-piece units of exercise equipment embodiments of the invention, wherein the right hand exerciser and the left hand exerciser are joined, should be used only with the right handgrip for the right hand and the left handgrip for the left hand. 
     Since certain changes maybe made in the described apparatus without departing from the scope of the invention herein involved, it is intended that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
