Multiple Layered Resistance Cables With Built In Resistance Handles And Interchangeable Hand Grips With Attachments

Abstract

cribes a resistant-type device, adaptable for use in exercise, utilizing a resistance cable constructed of multiple layers of resistance and protection. The resistance cable has a resilient inner core having a plurality of elastic members arranged in a substantially parallel manner. The plurality of elastic members are interlaced together to form a unitary stretchable main body unit, a first elastic looped portion positioned at a first end, and a second elastic looped portion positioned at a second end. In addition to the inner resilient core, resistance cable also contains at least one outer member and a protective layer coaxially aligned with the inner core. The outer member length is substantially coextensive with the length of the elastic inner core unitary stretchable main body unit. The device therefore, provides for the extension of the unitary stretchable main body unit from a first resting position to a second extended position upon application of a pulling force, whereby resistance to stretching of the unitary stretchable main body unit when extended from the first resting position to the second extended position upon application of the pulling force is greater than the resistance of each of the plurality of elastic members individually.

Description

CROSS REFERENCE TO RELATED APPLICATION

[0001]This application claims priority under 35 USC 119 (e) of the filing date of U.S. Provisional Application No. 61/208,634, filed on Feb. 26, 2009, entitled, "Multiple Layered Resistance Cable With Built In Handles And Interchangeable Hand Grips and Attachments", the contents of which are incorporated herein by reference.

FIELD OF THE INVENTION

[0002]The instant invention relates to a multi-purpose resistance cable, and more particularly to a multi-layered resistance cable, useful as an exercise device, with integral resistance handles and interchangeable hand grips and attachments. The multi-layered resistance cable as described herein provides for a resistance cable with enhanced strength, durability, and longevity resulting from the synergistic effects of the multiple layers.

BACKGROUND OF THE INVENTION

[0003]In addition to use as means for fastening or bundling objects, resistance bands have been useful in the exercise industry for numerous years. Using resistant bands as a means of strength training offers many advantages over free weight programs, and as such has been utilized by exercise users as either an enhancement to the use of weight or machine training or as a stand alone program. Traditional weight training methods using free weights and machine training offers different types of resistance in order to build muscle as compared to resistant cable training. Unlike free weights, a user of resistance cables in training exercises experiences resistance increases as the user pulls the cable further from the starting point. Another advantage to using resistant cables is that they are generally less expensive than using free weights or machines. While machines and free weight systems tend to cost hundreds of dollars, a complete set of resistant cables can be obtained at a fraction of the cost associated with free weights/machines. One of the main disadvantages associated with using free weights is the space requirement for storage, use and lack of portability. Resistant cables, however, are light weight, can be folded for portability and do not require extensive amounts of space for use. Moreover, most, if not all traditional exercises performed using free weights, such as squats, bench presses, or arm curls, can be performed using resistant cables.

DESCRIPTION OF THE PRIOR ART

[0004]One of the disadvantages of using resistance bands is that such bands can be constructed having unreliable structural integrity, making them hazardous for a user and endangering those around them. This unreliability in structural integrity is often a result of the handle connections and problems associated with the durability of the resistance bands themselves. Resistance bands with such unreliability in structural integrity employ a number of methods to secure handles to the resistance bands, including rubber tubing with handles fixated to both ends of the tubing. This fixation method utilizes pressure to secure handles to bands by lodging large objects within the tubing that prevent the handles from pulling off of the tubing during use. This method makes for a handle connection that can not be put under high pressure. If levels of high pressure accumulate between the handle and the lodged object, the lodged object intended to prevent the handle from being pulled off the tubing dislodges, risking the safety of the user and to those nearby. Other unanticipated and sudden malfunctions can occur in using these types of designs, resulting in unreliable devices and unsafe exercise environments.

[0005]Other resistance bands attach hooks or clasps on the ends of resistant tubing which are intended to connect the resistant tubing to separate handles. The hooks or clasps are constructed of materials ranging from plastics, metals or combinations. The handles to which they attach are made of fabric, metal, plastic, or foam. Needing this many materials to create an operable unit leads to an involved production process. More importantly, such a process creates more aspects of the unit that can break. Possibility for serious incident also increases when solid material, such as metal and plastic, are attached to the ends of rubber tubing. Upon breaking, these materials often whip around violently when released from tension.

[0006]The handles that connect to the bands also hinder the user with respect to mobility, reliability, versatility, comfort, and resistance transfer. The size, shape, and function of the grip can not be altered to accommodate for various exercises. The fabric or hard plastic handles have no elastic properties, leading to a break in resistance before contact with the user. Fabric handles have a natural tendency to tear and fray from contact with metal attachment pieces resulting in additional mishaps. The lack of resistance through the handle results in discomfort and complications for the user. The solid handles are uncomfortable when pulled at angles as the hard handle is either pressed against bones in the hands and arms, or places an angular strain on the wrist. These non-resistant handles hinder the full transfer of the band's resistant properties into the opposing muscles. Because these handles are intended to connect only to the ends of the resistant bands or tubing, a user is restricted in connecting handles to other parts of the band or tubing in order to obtain diverse resistance angles and exercise versatility.

[0007]In addition, most resistance bands employ only one band to endure all of the stress applied from the user's opposing muscles and generally do not utilize a protective layer covering the resistant material to aid in polymer longevity by protecting the polymer material from elements such as sun, air, and frictional degradation. When a single piece of rubber polymer begins to crack, tear, or split the small breach often results in complete break as further stress is applied to the already damaged rubber material. This break can occur with no warning. Serious injury can result from the violent whipping of the band, the user falling from the sudden loss of tension, and other hazards stemming from abrupt breaks in the resistance unit.

[0008]U.S. Pat. No. 4,694,541 discloses an elastic tie-down which includes an inelastic rope having enlargements captured by an elastic sleeve. The elastic sleeve is shorter than the spacing between the rope enlargements. Pulling the rope ends causes the rope enlargements to bear against the sleeve ends and stretch the sleeve. The rope ends are provided with hooks. The length between the hooks is adjustable without affecting the elastic properties of the tie-down by a clip that slidably receives the standing end of one of the rope ends extending from the sleeve. The clip also secures the rope end, thereby creating an adjustable sized loop in the rope. A hook is received over the rope in the loop. Sliding the clip along the rope standing end varies the size of the loop, thereby altering the length between the two hooks independently of the tension in the elastic sleeve. The rope and elastic sleeve, however, do not include handles nor are they used as an exercise device.

[0009]U.S. Pat. No. 4,754,531 discloses an elastic tie down which includes an elastic tube with a slack rope inside thereof. The tube is tightly crimped directly to the rope, so that pulling the rope ends stretches the tube and imparts elastic qualities to the tie down. In a different embodiment, an annular insert is placed into the ends of the tube, and the rope passes through the insert. The tube and insert are clamped, causing the insert to collapse to grip the rope. The elastic tie down also includes abutments crimped to the rope for cooperating with bushings placed within the tube ends. The bushings are split and have inwardly converging surfaces that terminate in grooves. Tension applied to the rope ends causes the abutments to contact the bushing converging surfaces and force the bushings apart and into a tight grip with the tube and with solid rings surrounding the tube over the respective bushings. The elastic tie down further includes split sleeves held in place in the tubing ends with wedges. A passage through the sleeves receives the rope. Abutments on the rope capture a rope slack between the sleeves. The rope and elastic sleeve, however, fail to include handles and are not useful as an exercise device.

[0010]U.S. Pat. No. 4,852,874 discloses an exercise device which includes 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 can be used to performing a wide variety of exercises and to perform 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 other 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 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. This device fails to disclose or teach an elastic core or band of cables surrounded by a tube or outer member.

[0011]U.S. Pat. No. 5,205,803 discloses a device which includes attachment elements connected to spaced ends of an elastic cord. A shroud extends the length of the cord between the attachment elements and is affixed to the attachment elements. The shroud is a tubular-shaped member forming a plurality of pleats when the elastic cord is in non-elongated condition. When the elastic cord is elongated and the shroud is not pleated it provides a positive restraint against further stretching of the elastic cord. The elastic cord, however, does not include handles nor is it used as an exercise device.

[0012]U.S. Pat. No. 6,202,263 discloses a unique safety sleeve elastic device having an elastic member of a certain longitudinal length. The elastic member provides stretching capability of up to seven times the elastic member's original length depending on the material selected. A flexible sleeve member is disposed around the elastic member. The sleeve member is less elastic than the elastic member and provides a stretch limitation to the elastic member to prevent a user from stretching the elastic member beyond a safe elongation. The ends of the sleeve and elastic members are secured adjacent to one another. Connectors are further secured to the ends of the elastic members. The elastic member provides stretch capability while the sleeve member provides safety features to protect the elastic member and the user. The elastic cord does not include handles nor is it used as an exercise device.

[0013]U.S. Pat. No. 6,418,594 discloses a device which is used to assist an individual with getting into and getting out of automobiles and other modes of transportation. The device includes an attaching member for attaching the device to the automobile and a connecting member which includes a handle that the user grasps during ingress and egress from the mode of transportation and an adjusting means that allows the device to be strategically located for a user's particular needs or preferences. This device does not include an elastic core or band of cables surrounded by a tube or other member. This device does not include handles nor is it used as an exercise device.

[0014]U.S. Pat. No. 7,077,793 discloses a pull exerciser device. The device includes a handle, an attachment member having a tubular portion and a loop portion, a resilient cord having an end attached to the tubular portion of the attachment member, and a belt extending through a through-hole of the handle and the loop portion of the attachment member. The tubular portion of the attachment member has an engaging hole through which the end of the resilient cord extends. A stop is embedded in the end of the resilient cord and partially inserted into the engaging hole of the tubular portion of the attachment member, thereby preventing the end of the resilient cord from disengaging from the tubular portion of the attachment member.

[0015]U.S. Pat. No. 7,377,886 discloses a pull exerciser which includes two attachment members, two positioning devices respectively attached to the attachment members at a location opposite to a grip portion of an associated attachment member, and at least one resilient cord. Each positioning device includes a positioning block and a positioning plate removably received in the positioning block. Each of the positioning blocks and the positioning plates includes at least one positioning hole. The resilient cord has two ends extendible through the positioning hole of each positioning block and each positioning plate. An end piece is fixed to each end of the resilient cord. The end pieces of the resilient cord are mounted to at least one of the positioning plates.

[0016]U.S. Pat. No. 7,458,135 discloses a tether having an elastic member which includes a non-stretched length having a first part and a second part. The first part of the non-stretched length has less elastic resistance than a second part of the non-stretched length thus altering the characteristics of stretch and recovery from a stretched length toward the non-stretched length under load and unloaded conditions. The tether does not include handles nor is it used as an exercise device.

[0017]U.S. Pat. No. 7,628,743 discloses a resistance exercise device having a handle which defines a plurality of holes and a cord having a pair of ends and a length extending between the pair of ends. The handle is secured to one of the ends of the cord. The cord is described as being stretchable from a relaxed state to an extended state the length of the cord. The cord contains a plurality of tubes extending substantially the entire length of the cord and having a pair of ends, the tubes being conjoined together along substantially the entire length of the cord by means of braiding. Each tube is received by a respective hole of the handle adjacent one of the ends of the tube. The device further has a structure engaging each tube to the handle adjacent the one end of the tube to prevent the tube from disengaging from the handle by preventing the one end of the tube from passing through the respective hole of the handle. The structure may comprise a plurality of plugs or other enlarged elements or any other suitable structure secured to a respective tube adjacent the one end of the respective tube to prevent the one end of the respective tube from disengaging from the handle.

[0018]None of the cited prior art, however, provides for a multi-layer resistance cable in which the layers synergistically operate to provide strength, durability, and enhanced safety while creating built-in resistance handles on both ends of the cable with interchangeable hand grips, bars, and other attachments designed to be applied to the cables, thereby providing increased exercise versatility and usefulness.

SUMMARY OF THE INVENTION

[0019]The instant invention describes a resistant-type device, adaptable for use in exercise, utilizing a resistant cable constructed of multiple layers of resistance and protective materials that form built in handles. The resistance cable has a resilient inner core. The resilient inner core has a plurality of elastic members having a desired resistance to stretching arranged in a substantially parallel manner. The plurality of elastic members are interlaced together to form a unitary stretchable main body unit, a first elastic looped portion positioned at a first end, and a second elastic looped portion positioned at a second end. The elastic loop portions function as built in handles. These handles increase comfort, resistance, and versatility in exercises and ensure the continuation of the resistant properties to the point of contact with the user. This continuation of resistance throughout the handle provides smooth and comfortable movements while exercising. It also increases isolation, concentration, and strengthening of muscles, ligaments, and tendons by completely and directly transferring the resistant properties of the cable to the opposing muscles of the user. The first and second looped portions allow for secure cable anchoring, and combining cables, along with many other possibilities. A stretch gel could also be used in place of the plurality of elastic members.

[0020]In addition to the inner resilient core, resistance cable contains at least one outer member coaxially aligned with the inner core. The outer member length is substantially similar or coextensive with the length of the elastic inner core unitary stretchable main body unit. The device therefore, provides for the extension of the unitary stretchable main body unit from a first resting position to a second extended position upon application of a pulling force, whereby resistance to stretching of the unitary stretchable main body unit when extended from the first resting position to the second extended position upon application of the pulling force is greater than the resistance of each of the plurality of elastic members individually. The resistance cable may also contain a third protective layer, the length of which being substantially the same as the length of the outer member, or covering some portion thereof. These layers operate synergistically to provide a user with a resistance cable having enhanced strength, durability, longevity, and safety. The resistance cable also contains various additional attachments, such as interchangeable hand grips, hooks, or long bars, secured to the looped portions, the body, or combinations thereof. These attachments offer a user a variety of applications including, but not limited to, use of weighted objects, use of a long bar, simultaneous use of multiple cables and other devices which may increases the user's comfort during use.

[0021]The instant invention further describes a resistance cable, the resistance cable having a resilient inner core. The resilient inner core has a plurality of elastic members, each having a desired resistance to stretching. The elastic members are arranged in a substantially parallel manner and are interlaced together to form a unitary stretchable main body unit, a first elastic looped portion positioned at a first end, and a second elastic looped portion positioned at a second end. The unitary stretchable main body and the first and second elastic looped portions are capable of extending from a first resting position to a second extended position upon application of a pulling force, whereby resistance to stretching of the unitary stretchable main body unit and the first and second elastic looped portions when extended from the first resting position to the second extended position upon application of the pulling force is greater than the resistance of each of the plurality of elastic members individually. The cable further contains at least one outer member coaxially aligned with the resilient inner core and having a length substantially similar to the length of the elastic inner core unitary stretchable main body unit, the first and second elastic looped portions, or combinations thereof. The resistance cable further includes a hollow flexible tubular member constructed and arranged to receive at least a portion of the resistance cable and to secure to a ball grip or a ball anchoring element. The ball grip or anchoring element is constructed and arranged for receipt of the hollow flexible tubular member and interconnection to the resistance cable. Optionally, the cable may include various hand grips and other attachment devices.

DETAILED DESCRIPTION OF THE INVENTION

[0072]FIGS. 1-3 refer to an illustrative example of a resistance cable. Referring to FIGS. 1 and 2 specifically, resistance cable 10 contains resilient inner core 12. The resilient inner core 12 has a unitary stretchable main body unit 14, a first elastic looped portion 16 located at a first end 18 and a second elastic looped portion 20 located at a second end 22. The looped portions can be used as handles. Because the handles are an integral part of the cable, they not only provide comfort to the user, but provide continuous resistance throughout the unit, increase fluidity of movements, and increase isolation and concentration of target muscles. Resistance cable 10 contains at least one outer member 24 coaxially aligned with the inner core 12. Outer member 24, may for example, be made of any commercial grade rubber resistance material. The length of the outer member 24 may be varied, covering all or a portion of the unitary stretchable main body unit 14. In an illustrative embodiment, the coaxially aligned outer member 24 has a length substantially coextensive with the length of the elastic inner core unitary stretchable main body unit 14. As shown in FIG. 2, element 26 illustrates a portion of outer member 24 which encloses the first elastic looped portion 16 located at the first end 18 and element 28 which encloses the second elastic looped portion 20 located at the second end 22. Securing elements 29 may be used to secure outer member elements 26 and 28 to the rest of outer member 24.

[0073]Resilient inner core 12 is made of individual elastic members 30. FIG. 3 illustrates an embodiment of elastic member 30 in the form a continuous ring. As illustrated in FIG. 4A, the inner core 12 contains multiple elastic members arranged in a parallel manner. In a preferred embodiment, the resilient inner core 12 has a plurality of elastic members in the form of rubber bands, see FIG. 4B. The elastic members 30 of resilient inner core 12 may, for example, be made of any commercial grade rubber, such as natural latex, resistance material. Each of the elastic members has a desired resistance to stretching and is arranged in a substantially parallel manner. Elastic members 30 are then twisted to form a rope-like, woven, braided, or the like, structure, thereby forming a unitary stretchable main body unit, a first elastic looped portion positioned at a first end, and a second elastic looped portion positioned at a second end, see FIG. 5. The rope-like, woven, braided, or the like, configuration is constructed such that when the cable is in an extended or non-extended state, the elastic bands that define the inner core remain in contact with each other, maintaining a tight, rope-like, woven, braided, or the like, configuration. The interlacing of the elastic bands, therefore, provides an inner core of resistance that is doubled through the body of the cable and exemplifies how the cable has the properties of increasing resistance while strengthening the unit from the inside out.

[0074]FIG. 6B illustrates a longitudinal cross section of the resilient inner core 12 illustrating the twisted configuration of elastic members 30 of resilient inner core 12 to form the unitary stretchable main body unit and the first and second elastic looped portions which can be used as handles. The ultimate thickness, length, and stretching characteristics of the resilient inner core therefore can be determined by the depth, size and stretching characteristics associated with the individual elastic members 30. One of the advantages of such construction is that the twisted construction allows for the formation of the unitary stretchable main body having enhanced overall resistance as compared to the resistance of the individual elastic members and the formation of a looped portion that can act as a handle.

[0075]FIG. 7 illustrates another particular embodiment of resistance cable 10 in which an outer member 24 encloses and is secured to a portion of the resilient inner core 12, such as the unitary stretchable main body unit 14. As illustrated, first elastic looped portion 16 and a second elastic looped portion 18 are not covered or enclosed by outer member 24. Outer member 24 may be secured to or positioned onto resilient inner core 12 by use of a probe 31 to pull the resilient inner core 12 into position through outer member 24, as illustrated in FIG. 8.

[0076]FIG. 9 illustrates an embodiment in which the first elastic looped portion 16 and the second elastic looped portion 18 are covered by outer member 24 as well. The outer member covering the elastic looped portions can be attached or fused together with a portion of the outer member that is covering the unitary stretchable main body unit 14 to form a unitary outer cover the length of the resistance cable, see FIG. 10, thus solidifying the unit and adding additional functionality, comfort, and physical benefits.

[0077]Referring back to FIGS. 4A and 4B, resistance cable 10 may also include additional protective layer member 32, coaxially aligned with and having a length that is partially or fully coextensive with the length of outer member 24. Protective layer member 32 can be made from any material which increases cable longevity by protecting the inner materials from sun, air, and frictional degradation when applied to the resilient cable 10. FIGS. 11A-E illustrate a particular embodiment of the multi-layered resistance cable 10. The multi-layered approach is further depicted by FIG. 11E, a cross-sectional view illustrating a first layer formed of a plurality of elastic members 30 defining the resilient inner core, 12, a second layer formed by the outer member 24, and the third layer formed by the protective layer 32. Clip 27 is used to secure protective layer 32 to resistance cable 10. Adhesive materials, such as LOCITE® Super Bonder, may be used to secure the layers as well. Attached to the first and second looped portions are interchangeable hand grips 34. In addition to increasing strength, durability, and shelf life, a multiple layer cable as described herein enhances safety and reliability by decreasing the chance of sudden failure due to a complete cable break. The multiple layers work synergistically to unify, strengthen, and reinforce the cable. One of the main drawbacks to the cited prior art devices utilizing a one layer band with a single layer of resistance is the increased risk of tearing, resulting in total breakdown of the device. By utilizing a multi-layered device, several layers must completely break before snapping can occur, making this cable as described herein less likely to total failure. In addition, multiple resistant layers offer greater opposition force with a thinner cable diameter. Thin cables create greater ease in multiple cable use, while stronger resistance capabilities satisfy broader work out requirements.

[0078]FIG. 12 illustrates a perspective view of an interchangeable hand grip 34, having a main body 36, a first open end 38, and a second open end 40. Hand grip 34 is positioned on a first looped portion 16 located at the first end 18 of a resistance cable and the second looped portion 20 located at the second end 22 of the resistance cable. As illustrated, interchangeable hand grip 34 is cylindrically shaped, however, such shape is illustrative only. Interchangeable hand grip 34 is designed to be directly attachable to a portion of the first or second elastic looped portions through open ends 38 and 40, providing the user improved comfort and ease of motion. Interchangeable grip 34 can be constructed to fit snuggly with the first or second looped portions or may be designed to provide a space 42 between the two sections such that additional resistance cables can fit within the interchangeable grip.

[0079]FIG. 13A illustrates another embodiment of an interchangeable hand grip 34. Hand grip 34 has a generally cylindrical shape which can be enclosed around the looped portion 16 of resistance cable 10 and capable of being engaged by a user's hand 44. Interchangeable hand grip 34 contains a hinge portion 46 which in an open position, see FIG. 13B, allows insertion of resistance cable 10 within inner lumen area 42. FIG. 13C illustrates interchangeable hand grip 34 partially enclosed around first elastic looped portion 16. Once fully closed, interchangeable hand grip 34 has a locking mechanism to secure the grip to the portion of resistance cable 10. Although FIG. 13C illustrates use of a locking arm 48 which is constructed and arranged in such a manner to engage a locking arm receiving area 50, other securing mechanisms, such as but not limited to, use of snaps, buttons, fastening hooks and loops, known to one of skill in the art can be utilized to secure the handgrip 34 in its closed position.

[0080]FIG. 14 illustrates another embodiment of the interchangeable hand grip wherein grip 34 is formed as a wrap 52. Wrap 52 can be made of a fabric material and contain fastening elements 54 and 56, such as but not limited to fabric loop and hook fasteners, such as VELCRO®, which connect each end of wrap 52 to form a cylindrical shape hand grip. While the grip is laid flat, a portion of resistance cable 10, such as the first and second elastic looped portions 16 and 20, respectively, are placed across the under side of the wrap, i.e. the opposite side as illustrated. Wrap 52 encloses resistance cable 10 through use of fastening elements 54 and 56, securing cable 10 within the grip. The fabric is supported with plastic inserts 58 placed into pockets 60 which are spaced along the outer side of wrap 52. Plastic inserts 58 give the grip support and solidity, while the spacing of the pockets allows flexibility for easy application/removal from cables. Use of such wrap to form an interchangeable hand grip offers a user a range of exercise applications and variations.

[0081]FIGS. 15-18 and 21 illustrate other particular embodiments of the interchangeable hand grip 34 formed as a partially cylindrical body 62 and sidewall 64. The partially cylindrical body 62 has a first open end 66, a second open end 68, and an inner hollow lumen 70. Partially cylindrical body 62 contains a longitudinal space 72 having a length substantially equal to the length of the cylindrical body 62 such that partially cylindrical body 62 has a cross section generally in the shape of a "C". Slots 74 are cut into the partially cylindrical body 62 and have a length substantially equal to the length of the partially cylindrical body 62. Sidewall 64 has two opposing flanges 76 and 78 constructed and arranged to slidably engage slots 74, thereby forming a full cylindrical body as illustrated by the cross sectional view of FIG. 18.

[0082]FIGS. 19-22 illustrate another embodiment of the interchangeable hand grip 34 having weight securing capabilities. FIG. 19 illustrates interchangeable hand grip having weight securing capabilities 34 in a closed position and contains a hand gripping area 80, a first weight fastening end 82 for receipt of a weighted object 84, a second weight fastening end 86 for receipt of a second weighted object 84, an inner lumen 88, and one or more resistance cable receiving areas or openings 90 for receipt or attachment to one or more resistance cables 10. FIG. 20 illustrates interchangeable hand grip having weight securing capabilities 34 in an open position. In the open position, interchangeable hand grip having weight securing capabilities 34 is divided into a first longitudinal portion 94 and a second longitudinal portion 96, traversable between a first closed position and second open position along line 92, see FIG. 19, through use of hinges 98, see cross sectional view illustrated by FIG. 21. FIG. 22 illustrates a cross section at one end of the embodiment of FIG. 19. The cross section of weight 84 secured onto grip 34 is illustrated.

[0083]In use, interchangeable hand grip having weight securing capabilities 34 provides a user the ability to add weight resistance to the resistance associated with resistance cable 10. The hinging function allows resistance cable 10 to fit within the interchangeable hand grip having weight securing capabilities 34 while open, and exit through one or more resistance cable receiving area opening 90. In use, the user holds the grip anywhere along the hand gripping area 80 so as to not interfere with the cables as they exit through one or more resistance cable receiving area opening 90. When resistance cable 10 is in place within the grip and exits through resistance cable receiving areas or openings 90, weighted objects 84 are fastened to first weight fastening end 82 and second weight fastening end 86, respectively. As illustrated, first weight fastening end 82 and second weight fastening end 86 have male or female threading for receipt of male/female threading 98 of weighted objects 84. In this manner, fastening occurs by screwing weighted objects into the threaded ends. Securing weighted objects onto threaded ends 86 and 88 while the grip is closed provides benefits to the user, including safely and easily adding weights to the grip, locking the grip closed, and trapping the cable inside of the grip thereby preventing cables from escaping during use. The weight securing hand grip can be composed of any solid material, such as metal or hard composite materials.

[0084]FIG. 23 illustrates another embodiment of the instant invention. Resistance cable 10 contains the same features as described previously, including having a resilient inner core, at least one outer member, and optionally a protective layer. A flexible member 92 encompasses at least a portion of resistance cable 10 and is constructed so as to attach to an anchoring member 94. As illustrated in FIG. 24, flexible member 92 has a first open end 96 for receipt of the resistance cable and a second open end 98 for engagement with a portion of the anchoring member. As illustrated in FIGS. 25 and 26, anchoring member 94 is a generally solid object, such as a rubber sphere, having a flexible member receiving area 100. Flexible member receiving area 100 receives a portion of flexible member 92, connectedly engaging flexible member 92 to anchoring member 94. For example, if flexible member 92 contains male threading, a portion of flexible member receiving area 100 will contain female threading, or vice versa. Anchoring member 94 also contains a resistance cable receiving member 102, such as but not limited to a hook, clamp hook, or the like, for receipt of at least a portion of resistance cable 10. The at least one intermediate interconnecting element 104 has a first end 105 for attachment to portion of the resistance cable and a second end 107 for attachment to the resistance cable receiving member. Resistance cable 10 may therefore attach directly to the resistance cable receiving member 102, or alternatively attach to an intermediate interconnecting element, 104, such as but not limited to a band clamp, screw or latch type clamps typically associated with attaching a workout machine cable to a particular handle grip/bar.

[0085]FIG. 27 illustrates a long bar attachment device 106 having a first member 108 interconnected to a second member 110 via threading positioning on a portion of member 108 and 110 respectively. Extended lengths can be achieved by combining multiple resistance cables 10 through interlocking the elastic looped portions together. Multiple resistance cables 10 can be pulled tight to allow the bar to screw together and connect while cables are inside of the long bar attachment device. Long bar attachment device provides the user additional workout variations and functionality. Cables are combined to create a long cable that can accommodate exercising with a long bar. In addition, weights may also be added to the bar.

[0086]FIGS. 28 and 29 illustrates additional attachments that can be added to resistance cable 10 to provide further versatility, allowing the user the ability to use one or more cables in a full range of resistance, creating multiple origins of resistance points, and providing stable anchoring in many diverse locations. FIG. 28 illustrates use of attachments, 112, such as but not limited to clamps, hooks, anchoring pulleys, or locking clasps, which are removably attached to the elastic looped portions, main body portion, or combinations thereof. Attachments 112 not only enhance exercising routines by providing additional resistant points, but also allow the user to use the resistance cable in securing cargo during transit and shipping. Multiple securing and anchoring sites give the user more versatility, capability and stability in securing and anchoring. FIG. 29 illustrates use of an additional attachment device in the form of a secondary handle 114, providing the user the ability to simultaneously utilizing multiple cables. Secondary handle attachment device 114 can be used to interconnect multiple elastic looped portions of multiple resistance cables 10. As an illustrative embodiment, FIG. 29 shows secondary handle attachment device 114 having a hand receiving element 116 which indirectly connects to a multiple resistance cable holding element 118 by a connecting element 120. Although resistance transfer is not as direct or smooth with the secondary handle attachment device 114, use of such device is beneficial because it enables unlimited simultaneous multi cable utilization, while employing a simple and safe cable handle design for connection. If desired, an interchangeable hand grip 34 may be attached to hand receiving element 116.
