reference will now be made to the accompanying drawings , which form a part hereof , and which show , by way of illustration , specific exemplary embodiments . the principles described herein may , however , be embodied in many different forms . the components in the figures are not necessarily to scale , emphasis instead being placed upon illustrating the principles of the invention . in some instances , example measurements are mentioned merely as illustrations of one or more embodiments and not to restrict the invention . moreover , in the figures , like referenced numerals may be placed to designate corresponding parts throughout the different views . an interchangeable rotating free - motion fitness handle system may provide more accurate and consistent results because the tube / cord is always stretching linearly and thus , it &# 39 ; s not manipulated by a fixed point . additional muscles can be targeted by using the rotational features . in one example of an interchangeable rotating free - motion fitness handle system , a fitness handle that features an opening “ oculus ” that permits a resistance tube anchoring mechanism to enter into a sliding channel such that when combined with a rotational - hand - grip , allows a fitness resistance tube equipped with a resistance tube anchoring mechanism to both pan left and right , as well as hinge up and down as users move through exercise motions is disclosed . a “ barb ” that may be located next to the oculus prevents the resistance tube anchoring mechanism from exiting the sliding channel when under any tension . a resistance tube anchoring mechanism can be a mechanism that is applied to the tail end ( s ) of plugged resistance tubes which allows for said tubes to be connected to tube accessories including interchangeable handle ( s ) and any appropriate accessories . such accessories may be equipped with , for example , a button - style fabric tube anchor point ( see fig1 for example ). of course , the length and resistance characteristics of the cables / stretch tubes the resistance tube anchoring mechanism is applied to can vary depending on the needs of the user . a hinge - locking tube anchor and pulley system may be a mechanism that allows users to create an anchor point from which they are able to generate resistance using resistance tubes . key features can include , but are not limited to , the outer ends of a component which allow sewn webbing loop , or suitable design , to be applied and removed from the component when said webbing is not under tension . the component may be made of , but of course , is not limited to plastic . other suitable materials may be also be used . when under tension , the webbing loops may secure the component as an anchor point , while allowing it to rotate , creating a pulley which responds to torsion friction applied by the fitness tube , thereby reducing wear / damage to the tube . this removable webbing loop design allows the hinge - locking tube anchor and pulley system to be secured to door hinges to create a superiorly secure anchor point , regardless of user orientation to the door . this allows the system to work on both open and closed doors , and offers the convenience of remaining in place when not in use , if the user so chooses . one additional feature is the larger pulley guide fins that define the outer limits of the pulley space . these large fins respond to pressure coming from the resistance tube , when in use , and adjust the orientation of the pulley to minimize wear on the tubes as different exercise movements are performed . a button - lock ankle / wrist attachment allows a sewn or otherwise connected cuff to be attached to body regions of the user without requiring hand - grip . the key feature is the sewn button lock ( slit ) which receives the resistance tube anchoring mechanism and holds it securely when under tension , similar to the manner a shirt button behaves . the length of fabric between the sewn button lock and the sewn attachment point to the cuff creates a flexible ‘ hinge ’ which allows the system to remain secure as orientation to the tube forces change . referring to fig1 , an exemplary embodiment of an interchangeable rotating free - motion fitness handle system is illustrated . interchangeable rotating free - motion fitness handle system includes cable / stretch tube / resistance band (“ fitness tube ”) 110 and interchangeable and rotational fitness handle system 120 . fig2 illustrates the components of an interchangeable rotating free - motion fitness handle system . fig2 includes an exemplary stretch tube / resistance band 110 , anchoring mechanism 210 and fitness handle 220 . flat slide surface 211 of anchoring mechanism 210 is also illustrated . fig3 - 5 illustrate various views of fitness handle system 120 . referring briefly to fig4 a and 5 , opening 410 allows the anchoring mechanism 210 to enter into a sliding channel 420 such that when combined with a rotational - hand grip 430 allows a fitness tube to both pan left and right , as well as hinge up and down as users move through exercise motions . barb 440 can prevent the anchoring mechanism 210 from exiting sliding channel 420 when under any tension . fig6 illustrates several embodiments of anchoring mechanism 210 including pill 610 , barrel 620 , and cone 630 . as can be seen , fitness tube 110 can be inserted into the anchoring mechanisms 610 , 620 , and 630 . fig7 a - 7c illustrate various embodiments of a fitness handle 220 . fig7 a - 7c also illustrate more detailed views of some embodiments of sliding channel 710 and rotational - hand grip 720 . fig8 illustrates various views of components of an embodiment of an interchangeable rotating free - motion fitness handle system . fig9 illustrates a more detailed view of the components of an embodiment of an interchangeable rotating free - motion fitness handle system . this embodiment of an interchangeable rotating free - motion fitness handle system includes clip lock 910 , plastic grip with tpr overmold 920 , frame / main body 930 , connection bar 940 and anchoring mechanism 210 . plastic grip with tpr overmold 920 may provide a comfortable grip to a user and may not be required . while this embodiment uses a plastic grip with tpr overmold , numerous alternative grips are also possible within the scope of the invention . the anchoring mechanism 210 includes resistance band insert 950 for inserting a resistance band . clip lock 910 may be made from a variety of different materials . in one embodiment clip lock 910 is made of plastic . other materials may be used within the scope of the invention . additionally , any specific measurements in this figure and others are illustrated to assist in the understanding of the invention and not to restrict or in any way limit the invention . fig1 illustrates detailed views of the components of one embodiment of a fitness handle . clip lock 910 , main body 930 , and connection bar 940 are further broken down to illustrate the components in detail . once again , measurements in fig1 are illustrated to assist in the understanding of the invention and not to restrict or limit the invention . fig1 illustrates detailed views of the components of grip 920 and resistance band insert 950 . fig1 illustrates one embodiment of a fitness cable anchor and pulley system . multi cable pulley 1210 may be designed such that it is wear reducing , thus increasing the life of the system . a rib 1220 may be added for strength purposes . loop 1230 may “ lock ” onto the pulley 1210 contour when under tension , and may completely encompass the hinge for added safety . loop 1230 may be sewn . the material of loop 1230 may be made of nylon but any other suitable material can also be used . the system may be used on both sides of the door 1240 . for example , an open door install may be configured to stay up when the door is opened or not in use . fig1 illustrates one embodiment of a button lock ankle / wrist attachment . in this embodiment , a velcro strap with a soft - inner - backer is used . fig1 illustrates one embodiment of a multi - attachment point fitness harness . fig1 illustrates one embodiment of a 360 degree rotating fitness harness . while various embodiments of the invention have been described , it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible within the scope of the invention . accordingly , the invention is not to be restricted , except as set forth in the following claims .
