DETAILED DESCRIPTION OF THE INVENTION

[0028] What is claimed, as seen in FIGS. 1-13, is a shoulder motion exercise device (10) and method of use. As seen well in FIGS. 3 and 4, one embodiment includes a hand-grippable slider (400). The slider (400) may be slidably engaged with an extender (300) having an extender axial length (305), a proximal end (310), an extender gripping portion (330) having a grip portion length (332), a distal end (320), and an extender slidable portion (340). In turn, the slidable portion (340) may have a slidable portion length (342), a proximal slider position (360) and a distal slider position (370) along the slidable portion length (342).

[0029] With further reference to FIGS. 3 and 4, the hand-grippable slider (400) may be coupled to a proximal end (210) of a connector (200) which may be coupled at a distal end (220) of the connector (200) to a retainer (100). In some embodiments the connector (200) is an elastic resistance connector (200), as will be described later in more detail. In such embodiments the elastic resistance connector (200) has an unstretched connector length. The retainer (100) is designed to be secured to a user (U) at, or above, the elbow. As will be explained later in greater detail, in some embodiments the retainer (100) may be a strap or brace securely attached to an arm of a user (U) to carry out the intended exercises. A retainer (100) is shown attached at the elbow in FIGS. 10 and 11, and above the elbow in FIGS. 5 and 6. In some embodiments the retainer (100) is a peri-condylar humeral (PCH) connector (100) specifically designed so as to be releasably securable to a peri-condylar area proximate to a humerus of a human user (U). As seen well in FIGS. 5 and 7, the elastic resistance connector (200) has a first functional length, in a first functional position with the human user (U), with the slider (400) positioned at the proximal slider position (360) of the extender slidable portion (340) and the connector (100) secured to the elbow, or the peri-condylar humeral area proximate to the humerus, of a human user (U). The first functional position is that where the retainer (100) is affixed to the elbow, or peri-condylar humeral area of the arm, of a user (U), the grippable slider (400) is slidably engaged with the extender (300) and is at the proximal slider position (360) along the extender slidable portion (300), and the human user (U) is gripping the grippable slider (400) and the extender grip portion (330) and has induced sufficient extension of the elbows so as to begin to stretch the elastic resistance connector (200) beyond the unstretched length.

[0030] As seen well in FIGS. 6 and 8, the elastic resistance connector (200) has a second functional length, in a second functional position with the human user (U), greater than the first functional length, with the slider (400) positioned at the distal slider position (370) of the extender slidable portion (340) and the connector (100) is secured to the elbow, or the pericondylar humeral area proximate to the humerus, of a human user (U). The second functional position is that where the retainer (100) affixed to the elbow, or the peri-condylar humeral area of the arm, of a user (U), the grippable slider (400) is slidably engaged with the extender (300) and is at the distal slider position (370) along the extender slidable portion (300), and the human user (U) is gripping the grippable slider (400) and the extender grip portion (330) and has induced sufficient extension of the elbows and torso rotation so as to stretch the elastic resistance connector (200) to a maximal exercising length.

[0031] In one embodiment the extender (300) includes a pair of stops to limit the sliding range of the slider (400), thereby defining the extender proximal slider position (360) as that position wherein the slider (400) rests against a proximal stop, and defining the extender distal slider position wherein the slider rests against a distal stop, and/or such stops may simply retain the slider (400) on the extender (300). In another embodiment the extender (300) includes at least one stop to limit the sliding range of the slider (400), such as a distal stop; whereas in an alternative embodiment the at least one stop includes a proximal stop. The stop, or stops, may be user adjustable for customization to the user's desired range of motion.

[0032] As may be inferred between FIGS. 5 and 6, and again between FIGS. 7 and 8, the elastic resistance connector (200) has a plurality of functional lengths with the slider (400) positioned at a plurality of positions between the proximal slider position (360) (FIGS. 5 and 7) and the distal slider position (370) (FIGS. 6 and 8) along the axial length of the extender (300) and the connector (100) secured to the elbow or the peri-condylar humeral area proximate to the humerus of a human user (U), and the arms are extended while the torso is rotated.

[0033] In some embodiments, the unstretched connector length is at least 6 inches, while in other embodiments the unstretched connector length is at least 10 inches. Similarly, in at least one embodiment, the unstretched connector length is less than 22 inches. In certain embodiments, the connector length increases by at least 2 inches when subjected to an axial tensile load of 5 bf, while in yet another embodiment the connector length increases by at least 4 inches when subjected to an axial tensile load of 5 lbf. In a further embodiment the connector length increases by no more than 8 inches when subjected to an axial tensile load of 5 lbf, while in yet another embodiment the connector length increases by no more than 6 inches when subjected to an axial tensile load of 5 lbf. Embodiments having a resistance connector (200) that is elastic provide additional comfort and safety during use, reducing the likelihood of overstretching the shoulder.

[0034] In various embodiments, by means of example only and not limitation, the slidable portion length (342) is at least 12 inches, while in other contemplated embodiments, the slidable portion length (342) is at least 24 inches, and in an even further embodiment the slidable portion length (342) is at least 30 inches. Further, in one embodiment the elastic resistance connector (200) has an ultimate tensile strength of at least 50 lbf, whereas in another embodiment it may have an ultimate tensile strength of at least 100 lbf, and in an even further embodiment the ultimate tensile strength may be at least 150 lbf. In an alternative embodiment the connector (200) is not elastic and elongates less than 5% under a tensile load of 150 lbf.

[0035] In some embodiments, such as that seen in FIG. 9, the slider (400) and the connector (100) are configured to accommodate releasable attachment of one or more connectors (200). In one such embodiment both the slider (400) and the connector (100) have an attachment ring, which may be rigid, such as plastic or metal, or flexible, such as fabric, nylon, or neoprene, just to name a few, to which one or more connectors (200) may be releasably attached. In such embodiments a kit may include multiple elastic resistance connectors (200) having different elastic properties so the user (U) may select the desired connector (200) and easily change them out depending on their strength and flexibility. In one such embodiment the kit includes at least two elastic resistance connectors (200), with one having at least 50% more stretch than the other when subjected to an axial tensile load of 5 lbf; whereas in a further embodiment the kit includes at least two elastic resistance connectors (200), with one having at least 75% more stretch than the other when subjected to an axial tensile load of 5 lbf; and in yet another embodiment the kit includes at least two elastic resistance connectors (200), with one having at least 100% more stretch than the other when subjected to an axial tensile load of 5 lbf. Alternatively, in another embodiment the kit includes at least two elastic resistance connectors (200) having the same elastic properties so that the use (U) can elect to exercise with a single connector (200), or multiple connectors (200). In one particular embodiment a connector (200) is constructed of surgical latex tubing having an inner diameter of approximately ¼″ and an outer diameter of approximately 7/16- 9/16″.

[0036] In some embodiments it is desirable to have the shoulder motion exercise device (10) possess a unique weight and weight distribution that is comfortable and easy to handle. One skilled in the art is familiar with U.S. Pat. No. 1,953,916 titled “Apparatus for Measuring Moments of Golf Clubs and the Like,” which discloses an instrument for measuring the amount of torque the weight of an object exerts about a pivoting fulcrum located 14″ from the end of the object. This device is particularly well known in the field of golf equipment. In one embodiment, with the closest portion of the slider (400) positioned 6 inches from the extender proximal end (310), an overall weight distribution of the extender (300) and the slider (400) produce a torque of 3000-10000 gram*inches about a fulcrum located 14″ from the extender proximal end (310), which is easily measured using such a swing weight apparatus. In a further embodiment the combined weight of the extender (300) and the slider (400) is 100-800 grams, thereby providing a weight and weight distribution that is comfortable and convenient to handle even for users undergoing shoulder rehabilitation. In an even further embodiment the weight and weight distribution is intended to mimic that of a golf club and the torque is 5000-8000 gram*inches, while in an even further embodiment the torque is 5500-7000 gram*inches, which closely simulates the weight distribution associated with a golf club having a swing weight of C3 through E7 on what is commonly referred to as the “Lorythmic” scale. In still a further embodiment that mimics the weight and weight distribution of a golf club the combined weight of the extender (300) and the slider (400) is 250-500 grams. In one embodiment the extender (300) is solid, in another embodiment the extender (300) is hollow, and in yet a further embodiment the extender (300) is tapered, while in an even further embodiment the extender (300) is hollow having a wall thickness that varies throughout at least a portion of the length.

[0037] Such embodiments are beneficial in achieving the desired weight and weight distribution. Further, the extender (300) may also include weights placed in the body of the extender (300) to achieve the desired weight and weight distribution. Even further, in another embodiment the extender (300) cooperates with at least one removably attachable weight so that the user may adjust the weight and weight distribution. Such weights may be designed to snap-on the extender (300) and in some embodiments may further act as the disclosed stops. An even further embodiment includes a repositionable sliding weight that may be adjusted along a portion of the extender (300), and in one embodiment the length of the sliding weight adjustability range is at least 12 inches, which in another embodiment is at least 24 inches. The extender (300) may be constructed of metallic or nonmetallic materials such as plastic, fiber reinforced plastic, and prepreg materials.

[0038] In another embodiment the extender (300) includes at least one elongated recess, or track, that cooperates with a portion of the slider (400) to eliminate rotation of the slider (400) as it travels along the extender (300). Alternatively, in another embodiment the extender (300) includes at least one elongated projection, or rail, that cooperates with a portion of the slider (400) to eliminate rotation of the slider (400) as it travels along the extender (300). The elongated recess or projection embodiments may further serve to limit the range of motion of the slider (400) along the extender (300).

[0039] In some embodiments, seen well in FIGS. 3 and 4, the retainer (100) may include a band having a width, a length, a first end (110), and a second end (120), wherein the first end (110) and second end (120) are releasably joinable at a retainer release point (130) to form a continuous band of a given circumference. The retainer (100) may incorporate a hook-and-loop fastening system, snaps, clips, or any easily functioning connection system that may be attached and removed by the user (U) using a single hand, while also affording the strength to carry out the stretches and exercises. One particular embodiment ensures the retainer (100) is secured at, or above, the elbow of the user (U) by incorporating a minimum adjustable size, or circumference, of at least 9″ so that it would be loose and nonfunctional around the wrist of the user (U), while in a further embodiment the minimum adjustable size of at least 11″, while in an even further embodiment the body of the retainer (100) is constructed of elastic material such that in an unstretched state the minimum adjustable size of at least 9″. In yet another embodiment the retainer (100) is configured as an elbow brace, as seen in FIGS. 12 and 13, having discreet portions for above-the-elbow and below-the-elbow, with the connector (200) joined to the above-the-elbow portion to further promote proper installation of the retainer (100) and stretching of the shoulder without bending of the elbow.

[0040] The grippable slider (400) is subject to a wide range of constructions, as one skilled in the art would immediately realize. For example, in one embodiment, seen well in FIGS. 7 and 8, the grippable slider (400) is a glove (550), having a sufficiently low coefficient of friction across the palm such that it might slide along a loosely held extender (300). In this embodiment the glove (550) is configured for attachment to the connector (200), which in a further embodiment is releasably attached to the connector (200). The extender gripping means (350) and/or the slider gripping means (450) may be any structure or textured surface meant to enhance the ability of the user (U) to grip the slider (400); in further embodiments, the extender gripping means (350) and/or the slider gripping means (450) may include a loop or other device for releasable fixation to the hand of the user (U), particularly for those with low grip strength. In another embodiment, the extender (300) may be the shaft of a golf club and the slider (400) may be any sort of hollow structure that might fit over and be releasably slidably engaged to the shaft. In one embodiment the shoulder motion exercise device (10) simply includes the retainer (100), connector (200), and slider (400), wherein the grippable slider (400) is sized and configured to slide over the butt-end of an existing golf club, allowing the user (U) to substitute their existing golf club for the extender (300). In this embodiment the slider (400) is configured with an interior opening that can pass a 1.25″ diameter obj ect. In yet another embodiment the slider (400) may be composed of multiple pieces that may be joined together once placed around an extender substitute, such as the golf club of the prior example. An even further embodiment incorporates a deformable slider (400) that does not totally encircle the extender (300), or extender substitute, and deforms to facilitate placement on the extender (300), or extender substitute. Other extender substitutes may include a broom, or mop, handle, a dowel rod, a section of pipe, or any object having an axial length sufficient to form an extender slidable portion (340) of sufficient length.

[0041] In another series of embodiments, the shoulder motion training device (10) may include a hand-grippable slider (400), slidably engaged to an extender (300), having an axial length, a proximal end (310), an extender gripping portion (330), a distal end (320). The extender (300) may have an extender slidable portion (340) having a proximal slider position (360) and a distal slider position (370) along the axial length. The hand-grippable slider (400) may be coupled to a proximal end (210) of an elastic resistance connector (200) coupled at a distal end (220) of the elastic resistance connector (200) to a retainer (100) which is, in turn, releasably securable to an arm of a human user (U). In one embodiment the extender gripping portion (330) is simply a textured friction-promoting surface to provide an adequate gripping surface during use, however in a further embodiment the extender gripping portion (330) is a separate grip structure applied to the extender (300), and in an even further embodiment the extender gripping portion (330) and slider (400) are sized and configured to simulate a conventional golf grip, however the extender gripping portion (330) remains fixed on the extender (300) while the slider (400) portion may separate from the extender gripping portion (330) and move along the extender (300). In a further embodiment the grip portion length (332) is 3.5″-8″ and the length of the slider (400) is 3.5″-8″, while in an even further embodiment the grip portion length (332) is 4″-7″ and the length of the slider (400) is 4″-7″. In yet another embodiment further promoting the feel and balance of a golf club the combined mass of the extender gripping portion (330) and slider (400) is 25-100 grams, while in a further embodiment the combined mass of the extender gripping portion (330) and slider (400) is 50-85 grams.

[0042] In such a series of embodiments, the device (10) may have a first operating position with the retainer (100) releasably secured at or above the elbow, in which the slider (400) is positioned at the extender proximal slider position (360), creating a first elastic resistance connector (200) functional length between the slider (400) and the retainer (100). Such a first operating position may be seen well in FIGS. 5 and 7. Similarly, a second operating position may be created with the retainer (200) releasably secured at or above the elbow, in which the slider (400) is positioned at the extender distal slider position (370), creating a second elastic resistance connector (200) functional length between the slider (400) and the retainer (100). Such a first operating position may be seen well in FIGS. 6 and 8. Between the first and second operating positions, there may then be a plurality of intermediate operating positions with the retainer (200) releasably secured at, or above, the elbow, in which the slider may be positioned at any point along the axial length of the extender (300) between the extender proximal slider position (360) and the extender distal slider position (370), creating a plurality of intermediate functional elastic resistance connector (200) lengths between the slider (400) and the retainer (100). These intermediate positions may be envisioned as the intermediate positions between that seen in FIG. 5 and FIG. 6, as well as those positions between that seen in FIG. 7 and FIG. 8.

[0043] One skilled in the art will easily recognize at least one method of using the device as taught herein in as a general stretching and exercise program, as may be prescribed for post-surgery rehabilitation, or to improve flexibility of the shoulders and strengthen the core and arms of an athlete for such sports as golf, tennis, racketball, baseball, football, cricket, softball, squash, handball, and any number of track and field events. A method for shoulder motion exercise may include, as a first step, releasably attaching a retainer (100) at, or above, the elbow of a human user (U). Next, the user (U) might grip an extender (300) having an axial length, a proximal end (310), an extender gripping portion (330) and a distal end (320). Such an extender (300) may have an extender slidable portion (340) having a proximal slider position (360) and a distal slider position (370) along the axial length, and be gripped across the palm in a first-side hand of the human user (U), on the same anatomical side as the first-side humerus, the first-side hand being on the same anatomical side as a first-side shoulder of the human user (U).

[0044] One may then place a hand-grippable slider (400), slidably engaged to the extender (300) at the proximal slider position (360) on the axial length of the extender (300). The hand-grippable slider (400) may coupled to a proximal end (210) of a connector (200) coupled at a distal end (220) of the connector (200) to the retainer (100). The user (U) may then grip the hand-grippable slider (400) across the palm in a second-side hand of the human user (U), the second-side hand being on the same anatomical side as a second-side shoulder of the human user (U) and opposite the anatomical side of the first-side hand and the first-side shoulder. Next, the user (U) may vertically elevate the first-side hand and second-side hand away from the torso, placing the second-side shoulder in a position of anterior adduction away from the torso of the human user (U). The first-side shoulder would then be in a position of anterior abduction across the torso, with the torso in a rotationally neutral position and both elbows in a position of extension, allowing the user (U) to angulate the distal end (320) of the extender (300) towards a position lateral to the second-side shoulder.

[0045] The user (U) would then simultaneously rotate the torso toward the second-side shoulder, horizontally abducting the first-side shoulder of the user and horizontally adducting the second-side shoulder while maintaining both elbows in extension, while at the same time moving the slider (400) from the proximal slider position (360) toward the distal slider position (370) along the axial length of the extender (300). One skilled in the art, in contemplation of FIGS. 5-8, will realize that in one embodiment the elastic component of the elastic resistance connector (200), being fastened at, or just above, the elbow of the user (U), will exert a force tending to help keep the elbow of the arm gripping the extender (300) from bending or flexing; thereby helping to mimic and encouraging the maintenance of good golf swing dynamics. Thus, in FIG. 6, the user's (U) movement of the slider (400) up the extender (300), while rotating the torso, results in the connector (200) pulling the left arm into a position that is most likely not ordinarily achievable during an ordinary practice swing, and stretches the muscles of the left shoulder and torso.

[0046] The exercise would then return to a starting functional position by simultaneously rotating the torso toward the first-side shoulder, horizontally adducting the first-side shoulder of the user and horizontally abducting the second-side shoulder while maintaining both elbows in extension, while at the same time moving the slider (400) from the distal slider position (370) to the proximal slider position (360) along the axial length of the extender (300). In certain embodiments, the first-side hand may be a functionally nondominant-side hand of the human user (U), while in others; the first-side hand is a functionally dominant-side hand of the human user (U). By alternating the side of the first-side hand, the user (U) may work towards stretching and strengthening both shoulders equally, as well as exercising the torso in rotation to both sides. One skilled in the art will appreciate how this same method and procedure may be likewise carried out using the glove embodiment of FIGS. 7 and 8. Further, the shoulder motion exercise device (10) may be a kit including the retainer (100), connector (200), and slider (400), in any of the disclosed embodiments; a kit including the retainer (100), connector (200), and glove (550), in any of the disclosed embodiments; and/or either of these kits further including an extender (300), in any of the disclosed embodiments.
