FIELD OF THE INVENTION
This invention generally relates to exercise apparatus and methods and more particularly relates to in-field kits and systems for self-directed therapeutic pulley-based muscle rehabilitation methods.
BACKGROUND OF THE INVENTION
Physical exercise on a regular basis obtains health benefits. For example, regular physical exercise has been shown to decrease the likelihood of cardiovascular disease, diabetes and cancer. Regular physical exercise may also reduce stress by releasing brain chemicals, such as serotonin, dopamine and norepinephrine. In addition, regular physical exercise reduces the likelihood of obesity and the deleterious psychological effects on one's body image due to being overweight.
In addition to the general health benefits of regular physical exercise mentioned hereinabove, regular physical exercise is often used to rehabilitate specific parts of the body after an injury or surgery. In this regard, appropriate physical exercise is used during physical therapy after an injury to or surgery on a specific part of the body. More specifically, physical exercise can help prevent scar tissue formation that might otherwise inhibit recovery after an injury or surgery. Appropriate physical exercise can also reduce joint stiffness, such as in the case of adhesive capsulitis, which is a debilitating disease causing limited motion in the shoulder joint where scar tissue has formed. Additionally, specific exercises promote cartilage lubrication, which helps in decreasing stiffness, increasing lubrication and Range of Motion (ROM).
Moreover, regular physical exercise is often used by athletes when training prior to a sporting event to avoid injury during the subsequent sporting event. For example, the hamstring muscle group is a group of muscles often over-strained by athletes, such as track runners and those who play football, hockey, basketball, soccer, baseball and other sports. The hamstring muscle group is found on the back of the hip and thigh and includes the biceps femonis, semitendinosus and semimembranosus. Injury to the hamstring muscle group is painful and there is often a prolonged recovery. However, appropriate and regular physical exercise targeting the hamstring muscle group when training prior to a sporting event can prevent or reduce likelihood of injury that might otherwise occur during the subsequent sporting event.
Further, regular physical exercise is often used by athletes to build muscle bulk, increase strength and enhance athletic performance. For example, tennis players find it beneficial to perform the chest cross exercise for conditioning the pectoralis major muscle, the lateral raise exercise for conditioning the deltoids, the biceps curl exercise for conditioning the biceps, as well as other exercises. As another example, baseball players find it beneficial to perform exercises that condition transverse abdominal muscles, rotator cuff and lower back muscles— Body builders and strength trainers also find it beneficial to perform regular physical exercise that target specific muscle groups to enhance muscle bulk and strength.
A gym is often used as a venue for regular physical exercise. However, gym membership is usually required to use the gym's facilities. Gym memberships can be expensive. For example, gym membership prices for an individual can average about $2,000 per year. A gym membership for a family costs even more. Also, gym membership is location-specific. That is, gym membership requires the user to use a gym facility at a specific location. In addition, weights in a gym are typically heavy and possess limited adjustment. Further, a particular gym may not possess equipment necessary to perform a desired exercise routine. Therefore, cost of gym memberships may be financially prohibitive for some individuals and families, gym membership limits users to specific locations, weights are heavy and have limited adjustment and equipment in some gym facilities may be inadequate.
In addition, it may be necessary to rehabilitate an accident victim or a professional athlete, who was injured because of his or her sport. In order to accomplish the rehabilitation, a physical therapist is often required to supervise physical exercises that facilitate the rehabilitation process. The rehabilitation may be on an on-going basis for an extended period of time and possibly for more than one region of the body (e.g., neck and shoulders). Given that rehabilitation may need to be performed over an extended period of time, the physical therapist will prescribe exercises that the accident victim or athlete should perform away from the physical therapist's facility, such as at home or at an athletic field. However, the current state of the art does not appear to provide suitable means for performing physical exercises away from the physical therapist's facility.
Approaches for obtaining the benefits of regular physical exercise not requiring gym membership have been proposed. In this regard, U.S. Pat. No. 6,949,035 titled “Power Swing Training Bar and issued Sep. 27, 2005 in the name of Robert M. Halsworth discloses a power swing training device that is a tethered, truncated device attached by flexible elastic to a fixed anchor point, or to a pulley and weight system. A swivel attachment is attached to the distal end of the training device, a yoke is attached to the swivel attachment, and an elastic cord is attached to the yoke at one end and to a fixed point at the other. In a second embodiment, a cord is hung on a pulley attached to an anchor and a weight is placed at the other end of the cord. However, this patent appears to be directed to specifically developing a baseball batter's muscles and improving batting strength and velocity and not necessarily related to other sports. In addition, this patent does not appear concerned with rehabilitating an injured accident victim or injured athlete.
Another approach is disclosed by U.S. Pat. No, 7,572,212 B2 titled “Portable Weightlifting Apparatus” and issued Aug. 11, 2009 in the name of Daniel Cassidy, et al. According to the Cassidy, et al. patent, a portable weightlifting device is disclosed having a segmented, separable, tubular housing that can be quickly and easily assembled and disassembled by a single user. The housing contains a movable weight that is coupled to a user interface outside of the housing by an inelastic cable that traverses two pulleys. Also, according to the Cassidy, et al. patent, one of the pulleys can be adjustably positioned for allowing a user to perform a multitude of exercises. However, it appears that a user must assemble the segmented housing prior to use and disassemble the segmented housing after use. Assembling and disassembling the segmented housing can be inconvenient for a user of the equipment, especially for an elderly person. In addition, this patent does not appear concerned with rehabilitating an injured accident victim or injured athlete. Further, it appears that a limitation of the Cassidy, et al, device is it only has three increments of weights. Combination of these weights to achieve a specific weight resistance desired by a user may be limited.
Yet another approach is disclosed by U.S. Patent Application Publication No. 2011/0130255 A1 titled “Hit Strong Power Trainer Systems” and published Jun. 2, 2011 in the name of Edward Carlton. This published patent application document discloses an exercising apparatus for strengthening particular variable muscle groups comprising a handle member including a threaded attacher and an elastic tether with a first and a second anchor at each of its two ends. The handle member comprises an elongated tubular plastic shaft with a length of twelve inches or less and has a proximal end comprising a knob and a distal end. The attacher comprises a ferrous eye hook and is fixed to the distal end of the handle member. The first anchor is fixed to the first end of the elastic tether and is removably clip-connected to the threaded attacher so as to connect the elastic tether to the handle member. The second anchor is fixed to the second end of the elastic tether and is removably clip-connected to a stationary vertical structure comprising a fence. However, this published patent document does not appear to disclose use of pulleys that can provide consistent resistance. Also, this device appears inconvenient to use because it requires substantial space to mount the device. In addition, the lowest weight achievable appears to be one pound. Moreover, the elastic tether that is connected to the handle member might prove to be a relatively weak link. In addition, this published patent application document does not appear concerned with rehabilitating an injured accident victim or injured athlete.
Although the prior art approaches recited hereinabove may disclose a power swing training device, a portable weightlifting device, and an exercising apparatus for strengthening particular variable muscle groups, the prior art recited hereinabove do not appear to disclose the invention described and claimed hereinbelow.
SUMMARY OF THE INVENTION
The present invention addresses the, shortcomings of the prior art approaches mentioned hereinabove by providing in-field kits and systems for self-directed therapeutic pulley-based muscle rehabilitation methods. Use of the present invention promotes wellness, prevention of injury, rehabilitation and performance optimization.
The in-field kits and systems for self-directed therapeutic pulley-based muscle rehabilitation methods comprises annular ring-shaped fasteners that can be attached to preselected locations on a stationary structure, such as a chain link fence that includes a wire mesh. In one embodiment, the ring-shaped fastener is a split first O-ring that defines a gap at the split in the first O-ring. At least one of the wires belonging to the wire mesh is passed through the gap, so that the wire is disposed within an open interior space defined by the first O-ring. The first O-ring includes an integrally connected screw-threaded latch near the location of the gap for opening and closing the gap. The screw-threaded latch is manually unthreaded to open the gap, so that the wire is received through the gap and into the open interior space defined by the first O-ring. The screw-threaded latch is manually threaded also to close the gap, so that the wire is enclosed, confined or captured within the open interior space defined by the first O-ring. In this manner, the first O-ring is coupled to the fence when the wire is captured within the open interior space defined by the first O-ring. In addition, a first pulley includes a ribbon or cord. The ribbon or cord is used to tie the first pulley to the first O-ring, so that the first pulley is coupled to the first O-ring. More specifically, the user can extend the ribbon or cord through the open interior space defined by the first O-ring, through an eyelet of an attachment belonging to the pulley and then tie the ribbon or cord into a knot. In this manner, the first pulley is coupled to the first O-ring. A second O-ring and second pulley are coupled to the fence in a similar manner.
In addition to O-rings and pulleys, in-field kits and systems for self-directed therapeutic pulley-based muscle rehabilitation methods also includes a tether, such as in the form of a rope, cord or the like for reasons provided presently. The tether is preferably an inelastic tether for reasons provided hereinbelow. However, the tether may be an elastic tether, if desired. In this regard, the user extends the tether over each of the pulleys, so that the tether traverses or spans all of the pulleys. The tether has a proximal end portion to which a handle is coupled. The handle is an elongate member, such as a truncated baseball bat, truncated tennis racquet handle, truncated hockey stick, truncated golf club or the like. The handle may also be in the form of a baseball. The tether also has a distal end portion to which a weight is coupled. The weight may comprise a weight bag containing dense material (e.g., one or more metal objects) or aggregate (e.g., sand, gravel and/or crushed stones). The weight may alternatively comprise incremental metal weights of a type familiar to body builders and strength trainers.
In use, the plurality of O-rings is coupled to the fence in the manner provided hereinabove. The user grasps the handle and moves the handle in order to pull on the tether that is coupled to the handle. The pulling action performed by the user places the tether, which spans the plurality of pulleys, in tension in order to lift the weight. The pulleys and the weight provide constant resistance to the user's movements and the resistance provides physical exercise for the user. Thus, each O-ring and pulley is configured to allow the plurality of O-rings and associated pulleys to be located at virtually any location on the fence in order to obtain a particularized exercise routine.
The invention provides an in-field kit and system for self-directed therapeutic pulley-based muscle rehabilitation methods that are versatile and convenient to use. In this regard, the in-field kit and system for self-directed therapeutic pulley-based muscle rehabilitation methods are configured to be quickly deployed on and removed from a stationary structure, such as a chain link fence. There may be a plurality of O-rings and pulleys coupled to the fence, each O-ring and pulley combination being locatable at any desired location on the fence. Thus, the O-ring and pulley combination can easily vary in number and location to achieve a particularized exercise routine, such as stretching of hamstring, deltoid and bicep muscle groups. In addition, use of the in-field kit and system does not require costly membership in a gym.
Moreover, the present invention is not limited to use with a chain link fence. Virtually any similar stationary structure is useable with the invention. For example, the present invention allows exercises to be performed using doors. In the case of doors, a specialized bracket is included that is adapted to removably connect to an edge of the door. The pulley, with or without the O-ring, is suspended from the bracket.
Use of the invention enables an athlete to make a transition from a clinic rehabilitation environment to an indoor or in-field environment for continuing his or her rehabilitation exercise routine. Use of the invention also allows an accident victim to make a rehabilitation transition from a clinical setting to an indoor (e.g., home) setting. In addition, use of the invention obviates the need to have a physical therapist present at all times during rehabilitation. The invention is a pulley-based system that enables use of the invention at home or at an athletic field.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from either the spirit or scope of the invention.
In addition, the present patent specification uses formal outline headings for clarity of presentation. However, it is to be understood that the outline headings are for presentation purposes, and that different types of subject matter may be discussed throughout the application (e.g., device(s)/structure(s) may be described under process(es)/operations heading(s) and/or process (es)/operations may be discussed under structure(s)/process(es) headings; and/or descriptions of single topics may span two or more topic headings). Hence, the use of the formal outline headings is not intended to be in any way limiting.
Therefore, with reference to FIG. 1, there is shown a first embodiment in-field kit and system for self-directed therapeutic pulley-based muscle rehabilitation methods, generally referred to as 10, in operative condition for use by a user 20. In this regard, first embodiment exercise kit and system 10 (hereinafter referred to as “first embodiment kit 10”) is beneficially used by user 20 to perform a plurality of exercise routines that selectively exercise desired muscle groups, such as the hamstring, deltoid, bicep and abdominal muscle groups.
It will be appreciated that first embodiment kit 10 is particularly useful for allowing an accident victim or a professional athlete, who was injured because of his or her sport, to rehabilitate the injury in an on-going, self-directed process without need of a physical therapist being present to direct the process. However, the accident victim or injured professional athlete will begin rehabilitation first by working-out under the direction of the physical therapist at the facility of the physical therapist. While under the direction of the physical therapist, the accident victim or injured professional athlete will acquire an understanding from the physical therapist as to what is required to rehabilitate injured muscles and ligaments, learn what exercises to use for rehabilitating the injured muscles and ligaments and also learn how to use first embodiment kit 10 for regaining strength, flexibility and other physical attributes. After working-out under the direction of the physical therapist for a necessary period of time (e.g., two weeks, four weeks or one month), the physical therapist will instruct the accident victim or professional athlete to perform predetermined exercises “at home” (i.e., away from the physical therapist's facility) for accomplishing the desired rehabilitation using first embodiment kit 10. In the case of the athlete, the exercises may be performed at home or at an athletic field (i.e., “in-field” exercising).
After the necessary period of time allotted for at-home or in-field exercising, the accident victim or professional athlete returns to the physical therapist for evaluation. If necessary, the physical therapist may modify the prescribed at-home or in-field treatment plan. Therefore, use of first embodiment kit 10 obviates the need to have a physical therapist present at all times during rehabilitation. In addition, as described in detail hereinbelow, first embodiment kit 10 is a pulley-based system that enables use of first embodiment kit 10 at home or in-field.
Referring again to FIG. 1, and as described in more detail hereinbelow, first embodiment kit 10 is adapted to be coupled to a stationary structure, such as a chain link fence, generally referred to as 30. Fence 30 is securely anchored in soil 35, such as by a footing 37, so that fence 30 is stationary. Fence 30, which forms no part of the present invention, includes a vertically oriented corner post or end post 40 having an upper end portion 50 and a lower end portion 60, the lower end portion 60 thereof being embedded in soil 35 by means of footing 37. A lower rail 70 is connected to and laterally extends from lower end portion 60 and includes a plurality of spaced-apart and aligned lower tension wire holders 80. The lower tension wire holders 80 are adapted to securely retain a lower tension wire 90 that extends parallel to and above lower rail 70 for reasons disclosed momentarily. In addition, an upper rail 100 is connected to and laterally extends from upper end portion 50 and includes a plurality of spaced-apart and aligned upper tension wire holders 110. The upper tension wire holders 110 are adapted to securely retain an upper tension wire 120 that extends parallel to and below upper rail 100 for reasons disclosed momentarily. In this manner, upper rail 100 and upper tension wire 120 run parallel to lower rail 70 and lower tension wire 90. A chain link mesh, generally referred to as 130, is connected to lower tension wire 90 and upper tension wire 120, so that chain link mesh 130 is secured in tension therebetween. Chain link mesh 130 includes a multiplicity of wires 140, which may be arranged in a criss-cross pattern, as shown.
Referring to FIGS. 1 and 2, and as described in detail hereinbelow, first embodiment kit 10 comprises a plurality of first embodiment ring-shaped fasteners, such as a first O-ring clip 150 adapted to be coupled to a first preselected location on chain link mesh 130 and a second O-ring clip 160 adapted to be coupled to a second preselected location on chain link mesh 130. As disclosed in detail hereinbelow, applicant's O-ring clips 150/160 are “screw-type” O-ring clips and are openable and closeable for individually positioning and coupling O-ring clips 150/160 at any desired location on chain link mesh 130.
Referring again to FIGS. 1 and 2, a first tensioning support, such as a substantially friction-free first pulley 170, is adapted to be coupled to first O-ring clip 150 and a second tensioning support, such as a substantially friction-free second pulley 180, is adapted to be coupled to second O-ring clip 160. Pulleys 170/180 may each be a commercially available pulley, such as an “ESP Single Swivel Pulley With Becket” ball-bearing type pulley which may be available from Harken Industrial Company, Incorporated located in Pewaukee, Wis., U.S.A. A smooth, high quality ball bearing construction for pulleys 170/180 offers a large range of resistance that is particularly useful for exercising the cervical spine (i.e., neck) and lumbar spine (i.e., lower back). The friction-free feature of pulleys 170/180, which is due to the ball bearing construction, allows for a smooth, constant resistance throughout the range of motion performed by user 20.
Referring yet again to FIGS. 1 and 2, a compliant or flexible tether 190, such as a flexible rope or cord, slidably engageably spans both pulleys 170/180 for reasons disclosed hereinbelow. Tether 190 is made of a synthetic material, such as polyethylene, aramid, carbon fiber or the polymer nylon. Tether 190 may be elastic, if desired, with a suitable elastic modulus for achieving a desired resistance to being pulled or tensioned. The elastic nature of tether 190 gradually increases resistance being experienced by user 20. Such a gradual increase in resistance may be preferred by some users. Preferably, however, tether 190 is substantially inelastic or non-recoil to avoid tether 190 snapping-back and hitting user 20 should tether 190 inadvertently break while being pulled. Tether 190 is also preferably substantially inelastic when performing the exercises to avoid any rebound effect on muscles, tendons and ligaments. Use of non-recoil or inelastic tether 190 obtains other benefits, as well. In this regard, such a non-recoil or inelastic tether 190 facilitates rehabilitation, sports training, injury prevention and improves physical performance. More specifically, when using non-recoil or inelastic tether 190, resistance is constant throughout range of motion from a shortened muscle position to a lengthened muscle position. Constant resistance, in turn, allows for specific dosage of exercises that obtains specific functional qualities, such as endurance, circulation, coordination and strength. Constant resistance also allows control of the range of motion and managing different types of exercises, such as concentric, isometric and eccentric exercises.
Still referring to FIGS. 1 and 2, first embodiment kit 10, which can be conveniently used in a home environment as described hereinbelow, is efficient and effective because the distance from pulleys 170/180 and the exercising components (e.g., weights, bats, and balls) is fixed by the length of inelastic tether 190. The inelastic tether 190, unlike an elastic tether, which is used by most, if not all therapists, is fixed in length, and will not vary in length when repeatedly used or when subjected to heat and cold in an outdoor environment. Thus, a therapist need not be present to verify whether prescribed exercises are performed with a resulting expected outcome. In this regard, it is difficult for elastic tethers to achieve expected outcomes because of the above-identified considerations associated with elastic tethers. When using an elastic tether, where the resistance changes with increased length of the elastic tether, one must take into consideration the age of the elastic tether and the possibility of the elastic tether “drying-up” (i.e., becoming stiff or brittle), decreased resistance capability and difficulty gauging progress because it is difficult to change and calculate a suitable weight/resistance. When using an elastic tether, resistance increases as muscle fibers move into an inefficient range of motion, thereby increasing risk of injury or leading to pathology if not closely monitored by a therapist.
Referring yet again to FIGS. 1 and 2, tether 190 has a proximal end portion 200 and a distal end portion 210. An elongate first embodiment dowel or handle 220, which is adapted to be connected to proximal end portion 210, includes a hook member 230 for engaging proximal end portion 210 of tether 190. Distal end portion 210 of tether 190 is adapted to be connected to a first embodiment weight, such as a weight bag 240. The weight bag 240 contains a dense material (e.g., one or more metal objects) or aggregate (e.g., sand, gravel and/or crushed stones). Alternatively, distal end portion 210 of tether 190 may be adapted to be connected to a second embodiment weight, such as a plurality of incremental weights 250 stacked one upon the other and of a type familiar to body builders and strength trainers. In either case of a weight bag 240 or incremental weights 250, the weights need not be heavy and can be readily adjusted to suit the individual strength capabilities of user 20.
In FIGS. 3, 4 and 5, user 20 is shown performing a first exercise routine, a second exercise routine and a third exercise routine, respectively. In the first exercise routine, user 20 has coupled O-ring clips 150/160 and associated pulleys 170/180 at preselected locations on chain link mesh 130. Tether 190 has been placed by user 20 over pulleys 170/180, such that tether 190 spans pulleys 170/180. First embodiment handle 220 is connected to proximal end portion 200 of tether 190 and incremental weights 250 are removably connected to distal end portion 210 of tether 190. User 20 moves first embodiment handle 220 in a desired manner and O-ring clips 150/160 in combination with pulleys 170/180, incremental weights 250 and tether 190 provide resistance to user's 20 movement of first embodiment handle 220. In the first exercise routine, user 20 is shown with an arm 255 moving first embodiment handle 220 in a downward arc from user's 20 abdominal region in order to exercise user's 20 forearm and bicep muscle groups. Exercising and strengthening of the forearm and bicep muscle groups may enhance performance in athletic activities, such as tennis and baseball. In the second exercise routine, O-ring clips 150/160 and associated pulleys 170/180 are located at other preselected locations on chain link mesh 130 for exercising some of the same muscle groups or completely different muscle groups. In this second exercise routine, both arms 255 are outwardly horizontally extended and both hands are shown grasping first embodiment handle 220. User 20 then moves first embodiment handle 220 either in an upward arc, laterally, and/or vertically in order to exercise user's 20 biceps and pectoral muscle groups. Exercising and strengthening of the bicep and pectoral muscle groups may enhance performance in athletic activities, such as baseball and hockey. In the third exercise routine, O-ring clips 150/160 and associated pulleys 170/180 are located at yet other preselected locations on chain link mesh 130 for exercising some of the same muscle groups or completely different muscle groups. In this third exercise routine, both arms 255 are outwardly horizontally extended to a side of user 20 and both hands are shown grasping first embodiment handle 220. User 20 then moves first embodiment handle 220 in a horizontal arc from side-to-side in order to exercise user's 20 bicep, pectoral, abdominal, hamstring and back muscle groups. Exercising and strengthening of the bicep, pectoral, abdominal, hamstring and back muscle groups may enhance performance in athletic activities, such as tennis, baseball, hockey and golf. Thus, based on applicant's teachings, it should be apparent to a person of ordinary skill in the art of exercise equipment design that placement of O-ring clips 150/160 and associated pulleys 170/180 at various preselected locations on chain link mesh 130 can obtain any one of a multiplicity of exercise routines in order to benefit specific muscle groups. The first, second and third exercise routines mentioned hereinabove are but examples of the multiplicity of possible exercise routines achievable by using first embodiment kit 10 and should not be construed as limiting. In addition to benefiting specific muscle groups, use of first embodiment kit 10 for purposes of regular physical exercise may improve overall physical health, including weight control.
Referring to FIGS. 6, 7, 8 and 9, the previously mentioned first embodiment ring-shaped fasteners comprising O-ring clips 150/160 will now be described in detail. For reasons of brevity, the description hereinbelow is directed to first O-ring clip 150, it being understood that the description hereinbelow applies to identical second O-ring clip 160, as well. In this regard, first O-ring clip 150 comprises an annular wall 260 having an outer surface 270 and an inner surface 280. The inner surface 280 defines an open interior space 290 within first O-ring clip 150. The first O-ring clip 150 also comprises an integrally connected first embodiment “screw-type” or “screw-threaded” latch mechanism, generally referred to as 295. First embodiment latch mechanism 295 comprises a pair of oppositely disposed parallel ledges 300a and 300b outwardly projecting from outer surface 270. Ledges 300a and 300b define an opening, split, channel or gap 310 between ledges 300a and 300b Gap 310 extends through wall 260 such that gap 310 is in communication with open interior space 290. Gap 310 facilitates coupling of first O-ring clip 150 to wire 140 that belongs to chain link mesh 130. More specifically, gap 310 is sized to receive wire 140 therethrough, which wire 140 passes through gap 310 and into open interior space 290. A pair of aligned internally threaded bores 315a and 315b transversely extend through ledges 300a and 300b, respectively. An externally threaded screw 320 is threadably received in internally threaded bores 310a and 310b. A wing nut 330 is threadably received onto an end portion of screw 320 and threaded thereon until wing nut 330 engages an underside surface of ledge 300b. In this manner, gap 310 is closed to block escape of wire 140 from open interior space 290. The process recited hereinabove is performed in reverse to remove first O-ring clip 150 from wire 140.
Referring again to FIGS. 6, 7, 8 and 9, first pulley 170 is adapted to be connected to first O-ring dip 150. For reasons of brevity, the description hereinafter is directed to connection of first pulley 170 to first O-ring clip 150. It being understood that the description hereinafter applies to an identical connection of second pulley 180 to second O-ring clip 160, as well. As previously mentioned, pulley 170 may be a commercially available pulley, such as the “ESP Single Swivel Pulley With Becker type pulley which may be available from Harken Industrial Company, Incorporated. Alternatively, however, pulley 170 may be of a different type according to applicant's design, which is described immediately hereinafter. In this regard, first pulley 170 comprises an axle 340 on which a grooved wheel 350 is rotatably mounted. Wheel 350 defines a grooved or recessed surface 360 extending around wheel 350. Previously mentioned tether 190 slidably engages recessed surface 360 as tether 190 spans first pulley 170. A pulley arm 370 interconnects axle 340 to a coupling 380 defining an eyelet 390 therethrough. A connector 400 connects coupling 380 to first O-ring 150 and, thus, connects first pulley 170 to first O-ring 150. Connector 400 may be a rope, ribbon or cord that extends through eyelet 390 and open interior space 290 and that is tied into a knot 405 for securely connecting first pulley 170 to first O-ring 150. Alternatively, connector 400 may be ring-shaped fastener as described hereinbelow or a commercially available “BLACK DIAMOND OVAL carabiner clip which may be available from REI, Incorporated located in Summer, Wash., U.S.A.
As best seen in FIGS. 10 and 11, there is shown a second embodiment ring-shaped fastener, generally referred to as 410. Second embodiment ring-shaped fastener 410 comprises a “gate-type” O-ring clip 420 and is distinguishable from applicant's previously mentioned “screw-type” O-ring clips 150/160, More specifically, gate-type O-ring clip 420 comprises an annular wall 430 having an outer surface 440 and an inner surface 450. The inner surface 450 defines an open interior space 460 within gate-type O-ring clip 420. Wall 430 defines an entrance 470 therethrough that is in communication with open interior space 460 for reasons made apparent presently. Gate-type O-ring clip 420 defines an arcuate-shaped first chamber 480 therein having a closed rear portion 490 and an open front portion 500. Disposed in rear portion 490 of first chamber 480 is a resilient biasing member, such as a coiled spring 510, for purposes disclosed momentarily. Spring 510 engages an arcuate-shaped plug or gate 520 that is matingly slidably disposed in first chamber 480 and that extends from entrance 470 to spring 510, such that spring 510 engages gate 520. Gate-type O-ring clip 420 also defines an arcuate-shaped second chamber 530 therein having a closed rear portion 540 and an open front portion 550. Open front portion 500 of first chamber 480 and open front portion 550 of second chamber 530 are aligned one to another and are in communication with entrance 470. Entrance 470 facilitates coupling of gate-type O-ring clip 420 to wire 140 that belongs to chain link mesh 130. In this regard, entrance 470 is sized to receive wire 140 therethrough, which wire 140 passes through entrance 470 and into open interior space 460. More specifically, gate 520 is grasped by user 20 and manually moved in first chamber 480 in a direction of an arrow 555 toward rear portion 490 of first chamber 480. As gate 520 moves in direction of arrow 555, entrance 470 opens because entrance 470 is no longer blocked by gate 520. Also, as gate 520 moves in direction of arrow 555, spring 510 compresses. Gate-type O-ring clip 420 is thereafter coupled to wire 140 belonging to chain link mesh 130 in the manner described presently. In this regard, wire 140 is passed through entrance 470 to be received into open interior space 460. At this point, gate 520 is manually released by user 20, so that gate 520 travels in a direction of an arrow 557 to be received into second chamber 530. Travel of gate 520 in direction of arrow 557 is caused by expansion of spring 510 which expansion is, in turn, caused by user's 20 manual release of gate 520. In other words, manual release of gate 520 causes spring 510 to be released from spring's 510 compressed state, such that spring 510 expands to move gate 520. In this manner, entrance 470 is closed to block escape of wire 140 from open interior space 460, so that gate-type O-ring clip 420 is removably coupled to wire 140 that belong to chain link mesh 130. The process recited hereinabove is performed in reverse to remove gate-type O-ring clip 420 from wire 140.
As best seen in FIG. 12, wall 430 of gate-type O-ring clip 420 may optionally define an arcuate-shaped slot 560 therein aligned with and adjacent to gate 520. An optional tab 570 that is integrally connected to gate 520 outwardly projects from gate 520 and extends through slot 560. Tab 570 may be grasped by user 20 and moved in the direction of previously mentioned arrow 555 for conveniently moving gate 520 toward rear portion 490 of first chamber 480. As tab 570 is moved in the direction of arrow 555, entrance 470 is opened. Conversely, when tab 570 is released, previously mentioned spring 510 expands to move gate 520, so that entrance 470 is closed by gate 520.
Referring to FIG. 12A, there is shown a third embodiment ring-shaped fastener, generally referred to as 572. Third embodiment ring-shaped fastener 572 comprises a threaded “coupler latch” O-ring clip 574a having a generally annular wall 574b of circular transverse cross-section. Wall 574b has an outer surface 574c and an inner surface 574d. The inner surface 574d defines an open interior space 574e within gate-type O-ring clip 574a. Wall 574b defines an entrance or gap 574f therethrough that is in communication with open interior space 574e for reasons made apparent presently. Entrance 574f facilitates coupling of gate-type O-ring clip 572 to wire 140 that belongs to chain link mesh 130. In this regard, entrance 574f is sized to receive wire 140 therethrough, which wire 140 passes through entrance 574f and into open interior space 574e when gate-type O-ring clip 574a is opened. Due to presence of entrance 574f, wall 574b has a first end portion 574g that is externally threaded and a second end portion 574h that is also externally threaded. An adjustable, generally cylindrical coupler member 574i is adapted to threadably engage first end portion 574g and second end portion 574h. For this purpose, coupler member 574i defines a central, threaded internal bore 574j therethrough for threadably engaging the external threads of first end portion 574g and second end portion 574h. Coupler member 574i may also have a textured external surface 574k for allowing user 20 to easily grip and turn coupler member 574i, Turning coupler member 574i, such as in the direction of an arrow 574l, will cause coupler member 574i to threadably advance along first end portion 574g and threadably engage second end portion 574h, thereby closing entrance 574f. Turning coupler member 574i, such as in the direction of an arrow 574m, will cause coupler member 574i to threadably retreat along first end portion 574g and threadably disengage second end portion 574h, thereby opening entrance 574f. Thus, manipulation of coupler member 574l allows wire 140 to be received through entrance 574f, when entrance 574f is opened, and captured within interior space 574e when entrance 674f is closed. Manipulation of coupler member 574l also allows wire 140 to be received through entrance 574f and released from interior space 574e. In this manner, configuration of coupler member 574i allows coupler member 574i to be conveniently releasably attached to fence 30.
Referring to FIG. 12B, there is shown a fourth embodiment ring-shaped fastener, generally referred to as 576. Fourth embodiment ring-shaped fastener 576 comprises a generally annular wall 578a. Wall 578a has an outer surface 578b and an inner surface 578c. The inner surface 578c defines an open interior space 578d within ring-shaped fastener 576. Wall 578a defines an entrance or gap 578e therethrough that is in communication with open interior space 578d for reasons made apparent presently. Entrance 578e facilitates coupling of ring-shaped fastener 576 to wire 140 that belongs to chain link mesh 130. In this regard, entrance 578e is sized to receive wire 140 therethrough, which wire 140 passes through entrance 578e and into open interior space 578d when ring-shaped fastener 576 is opened. Entrance 578e of ring-shaped fastener 576 is opened and closed by means of a resilient gate member 578f spanning entrance 578a and that is bendable about a pin 578g that couples gate member 578f to wall 578a. Gate member 578f is capable of being manually bent to a bent state 578h generally in the direction of an arrow 578i, as shown, for opening entrance 578e. Gate member 578f will return to its original unbent state, in the direction of an arrow 578j, upon manual release thereby closing entrance 578e. A type of fastener suitable for this purpose can be a commercially available “TMS-CB156” carbiner clip that may be available from Qinfeng Electric Machinery Company, Ltd. located in Fuzhou City, Fujian Province, China (Mainland).

The weight bag 240 may have had the weights emptied therefrom to enable weight bag 240 being folded and placed in tote bag 840. Alternatively, tote bag 840 may serve as a weight bag, as well as a storage bag. Tote bag 840 defines an opening 860 for allowing access to inner volume 850. Opening 860 may be opened and closed by any suitable means, such as by a zipper 870. Tote bag 840 may be made from a pliable material, such as nylon, cloth or the like. Alternatively, tote bag 840 may be in the form of a metal case (not shown), made from a light weight metal that, for example, might be thin gauge aluminum.
Turning now to FIG. 21, there is shown a second embodiment in-field kit and system for self-directed therapeutic pulley-based muscle rehabilitation methods, generally referred to as 880 (hereinafter referred to as “second embodiment kit 880”), that may be used in an indoor environment (e.g., at home, at a hotel) or at an athletic field. When used in an indoor environment, second embodiment kit 880 is deployable on a conventional door 890 that may be hinged to an upright wall 900 by means of a hinged connection 910. Door 890 has a first side edge portion 920a, a second side edge portion 920b, a top edge portion 920c, a front surface 925 and a rear surface (not shown). A conventional upper door frame portion 927 is disposed opposite top edge portion 920c of door 890, such that a gap 929 is defined therebetween. Conventional door 890, wall 900, hinged connection 910 and upper door frame portion 927 form no part of the present invention. Previously mentioned first pulley 170 is removably suspended from first side edge portion by means of a flexible member, such as a flexible ribbon 930 that may be made of a thin gauge cloth. More specifically, ribbon 930 may be heavy duty double stitched webbing and has a distal attachment made of a plastic polymer material. Ribbon 930 is configured such that the distal attachment is securely wedged between first side edge portion 920a and wall 900 when door 890 is closed. By way of example only, and not by way of limitation, the distal attachment may be a commercially available component, such as a TRIGLIDE™ metal or plastic buckle or fastener that allows for strap or webbing adjustments, such as may be available from ITW Nexus, Incorporated located in Des Plaines, Ill. U.S.A.
Referring again to FIG. 21, a bracket assembly, generally referred to as 940, is removably mounted on top edge portion 920c of door 890 for removably suspending previously mentioned second pulley 180 therefrom. Bracket assembly 940, which may be steel for durability, is configured to fit virtually any thickness of door 890. In this regard, bracket assembly 940 is adjustable to fit most home doors and industrial size doors. This ability to adjust bracket assembly 940 to fit both size doors adds to the useable applications because bracket assembly 940 can fit on doors at home as well as most businesses and hotel rooms. In this regard, bracket assembly 940 comprises a vertical first leg 950a, a vertical second leg 950b disposed parallel to and opposite first leg 950a and a thin horizontal intermediate plate 950c interconnecting first leg 950a and second leg 950b. When bracket assembly 940 is deployed on top edge portion 920c of door 890, first leg 950a is disposed opposite front surface 925, second leg 950b is disposed on the rear surface of door 890 and thin intermediate plate 950c spans top edge portion 920c of door 890. Thus, thin intermediate plate 950c is thin enough to be disposed in gap 929. An externally threaded pin 960 is threadably received through an internally threaded bore (not shown) formed transversely through first leg 950a. Pin 960 includes a protective felt-padded or rubber-padded end portion 970 for abutting against front surface 925 of door 890. End portion 970 is felt-padded or rubber-padded to avoid damage or marring of front surface 925 while bracket assembly 940 is mounted on door 890. In this manner, bracket assembly 940 is removably secured to door 890 without damaging or marring door 890.
Referring to FIG. 21A, an alternative bracket assembly 965 need not include pin 960 and the bore associated therewith. Alternative bracket assembly 965 is flexible enough, as illustrated by dotted lines in the figure, to adjustably fit various thicknesses or sizes of door 890 and has a felt-padded or rubber padded layer 965a on an underside thereof for preventing damage or marring of door 890. Alternative bracket assembly 965a defines a through bore 965b for attachment of either one of pulleys 170/180. Tether 190 can then span pulleys 170/180. Handle 220 and incremental weights 250 can then be connected to tether 190 and used to perform the previously mentioned exercise routines. A multipurpose strap may be coupled to an end portion of tether 190, if desired. In this regard, the previously mentioned eighth embodiment handle 839 having strap portion 839a wraps about a portion of the head, leg, ankle or other body part of the user for exercising that body part of the user.
Returning to FIG. 21, use and configuration of second embodiment kit 880 will now be described in greater detail. In this regard, second embodiment kit 880 enables an athlete to make a transition from a clinic rehabilitation environment to an indoor or in-field environment for continuing his or her rehabilitation exercise routine. Second embodiment kit 880 is constructed to provide such an athlete with a constant resistance routine, where a constant resistance level may not only be incrementally varied, but may also be adjusted over a wide and diverse range of exercise positions for exercising a given muscle group of the athlete. Although second embodiment kit 880 is constructed to enable an athlete to make a transition from a clinic rehabilitation environment to an indoor or in-field environment for continuing his or her rehabilitation exercise routine, it should be understood by those skilled in the art, that second embodiment kit 880 may also be utilized by an accident victim making a rehabilitation transition from a clinical setting to an indoor (e.g., home) setting. When used by an athlete in an in-field environment, second embodiment kit 880 can be supported by any suitable stationary structure, such as previously mentioned wire fence 30. Therefore, use of second embodiment kit 880 obviates the need to have a physical therapist present at all times during rehabilitation. In addition, second embodiment kit 880 is a pulley-based system that enables use of second embodiment kit 880 at home or in-field.

Again, with reference to the body specific exercise attachment devices or handles 220/630/660/700/740/835/837, the body specific exercise attachment devices or handles 220/630/660/700/740/835/837 are examples of a variety of different forms and structures for the specific exercise attachment devices. The specific form and structure of the exercise attachment device is selected based upon the specific muscle group of the athlete that must be strengthened or rehabilitated. In this regard, the body specific exercise attachment device is selected from a group of body specific exercise attachment devices, including but not limited to first embodiment handle 220, second embodiment handle 630 (i.e., lower portion of a truncated baseball bat), third embodiment handle 660 (i.e., lower portion of a truncated tennis racquet), fourth embodiment handle 700 (i.e., lower portion of a truncated hockey stick), fifth embodiment handle 740 (i.e., handle with pivotable yoke), sixth embodiment handle 835 (i.e., baseball), and seventh embodiment handle 837 (i.e., strap device). Each of these body specific exercise attachment devices were described in detail hereinabove. Thus, based on the description hereinabove, first embodiment handle 220 is for lifting and pulling constant weights ranging from about 200 grams (i.e., about 0.441 pounds) to about 9.072 kilograms (i.e., about 20 pounds); second embodiment handle 630 is utilized for exercising the muscle groups associated with swinging a club-like device, such as a baseball bat, a golf club, and the like; third embodiment handle 660 is utilized for exercising muscles associated with playing tennis; fourth embodiment handle 700 is utilized for exercising muscles associated with playing hockey; fifth embodiment handle 740 is utilized for exercising muscles requiring a pivotable yoke; sixth embodiment handle 835 is utilized for exercising the muscle groups associated with throwing a ball; and the seventh embodiment handle 837 is utilized for exercising a diversity of muscle groups, such as a neck muscle group, a shoulder muscle group, an arm muscle group, an ankle muscle group, a leg muscle group, and a knee muscle group, as previously mentioned.
Therefore, based on the description hereinabove, and with reference to FIGS. 1 and 21, first embodiment kit 10 is configured as an outdoor tensioning arrangement and second embodiment kit 880 is configured as an indoor tensioning arrangement or an outdoor tensioning arrangement. In this regard, second embodiment kit 880 is adapted to be mounted to a door jamb, such as first edge portion 920a that serves as a door jamb, while the outdoor tensioning arrangement or first embodiment kit 10 is adapted to be mounted to previously mentioned wire fence 30, such as one would find anchored in soil 35 on an athletic field. Regardless of the type of mounting that is selected for the tensioning arrangement, first embodiment kit 10 and second embodiment kit 880 may both be configured to provide a plurality of different mounting configurations ranging from an apex position relative to the first edge portion 920a that serves as the door jamb or wire fence 30, to a floor or ground position, with a plurality of other mounting positions therebetween selected based upon how the athlete desires to exercise a given muscle group.
With reference to FIG. 21, second embodiment kit 880 includes either incremental weights 250 or weight bag 240 having a sufficient volume to hold a variety of weights ranging between about 200 grams 200 grams (i.e., about 0.441 pounds) and about 9.072 kilograms (i.e., about 20 pounds). Tether 190 is adapted for attachment at one of its ends to the weight bag 240, weights 250 and to a selected one of the body specific exercise attachment devices or handles 220/630/660/700/740/835/837 at another one of its ends depending upon the type of exercise to be performed. The indoor tensioning arrangement or second embodiment kit 880 further includes previously mentioned bracket assembly 940, first pulley 170 positioned on door 890, and second pulley 180 positioned on door 890 at an apex position above first pulley 170. Both first embodiment bracket assembly 940 and second embodiment bracket assembly 965 are provided with a protective lining or layer, such as felt-padded or rubber, so that the bracket assembly does not damage or mar door 890. Second embodiment bracket assembly 965 is constructed of a sufficiently pliable material so that second embodiment bracket assembly 965 may be configured to snugly grip a wide door jamb or a narrow door jamb. In this regard, second embodiment bracket assembly 965 may be configured to be utilized with a door jamb having a maximum width of 1.5 inches to a minimum width of 3.5 millimeters.
Referring to FIGS. 218 and 21C, there is shown a tensioner 972 for adjustably tensioning tether 190. Tensioner 972 defines a plurality of through-holes 972a, such as three through-holes 972a, for receiving an end portion of tether 190. The end portion of tether 190 is interleaved through through-holes 972a to a suitable extent in order to achieve the desired tension in tether 190 and tied into a knot 972b to retain the end portion of tether 190 in tensioner 972 and to retain tether 190 at the desired tension.
Thus, it may be appreciated that neither first embodiment kit 10 nor second embodiment kit 880 requires use of gym facilities. It may also be appreciated that first embodiment kit 10 and second embodiment kit 880 are convenient to use because these embodiments require less space in which to use them compared to some conventional exercise devices. In addition, the weights are readily adjustable so that the weights can be reduced to a minimum amount, such as 200 grams, if desired. In addition, if desired, tether 190 need not be elastic material in order to reduce the risk that tether 190 might become a weak link. Preferably, tether 190 is inelastic for the reasons mentioned hereinabove. Further, first embodiment kit 10 and second embodiment kit 880 offer accurate dosage of exercise in order to achieve functional qualities, such as vascularization, detonification, coordination, endurance, strength and power. First embodiment kit 10 and second embodiment kit 880 are versatile to accommodate different resistances to meet the specific needs of a relatively full range of exercise routines. Further, use of first embodiment kit 10 and second embodiment kit 880 obviates a need to have a physical therapist present at all times during rehabilitation. In addition, first embodiment kit 10 and second embodiment kit 880 are each a pulley-based system that enables use of first embodiment kit 10 and second embodiment kit 880 at home or in-field.
