An upper handle 70 similarly extends upwardly from the handle hub 60, the upper handle 70 being either fixedly secured thereto or rotatably locked thereto.

[0050] The phrase handle assembly is used herein to mean one of two handle assemblies 11, 12 located upon an exercise apparatus, the assemblies 11, 12 being mirror images of each other, both of which are located on an axis orthogonal to the longitudinal axis of the exercise apparatus. It should be recognized that the description of, or reference to one handle assembly 11 shall apply to a second handle assembly 12 that is substantially a mirror image of the first.

[0051] Further, although handle assembly implies the human interface contact point of an exercise machine 90 upon which human hands are placed, the disclosure is not limiting, and can be interchangeably mean foot bar assembly upon which a person may push against using their feet in order to primarily exercise the muscles of the legs and back.

[0052] i. Mounting Bracket.

[0053] The handle assembly 11 will generally include a mounting bracket 20 having an upper end 21 and a lower end 22. The mounting bracket 20 may be comprised of various structures, devices, and configurations adapted to be removably secured to an exercise machine 90 such as a pilates machine as shown in the figures.

[0054] In a preferred embodiment as best shown in FIGS. 3-4, the lower end 22 of the mounting bracket 20 will include a clamping structure having an aperture 23 through which a securing member 24 such as a pin or fastener may be threadably secured to removably secure the mounting bracket 20 to the exercise machine 90.

[0055] FIG. 2 best illustrates a mounting hub shaft 30, which extends upwardly from the upper end 21 of the mounting bracket 20. The mounting hub shaft 30 may be integrally formed with the mounting bracket 20 or they may be comprised of discrete structures secured together.

[0056] Although the figures illustrate the mounting hub shaft 30 being hollow, it is appreciated that, in some embodiments, the mounting hub shaft 30 may be solid. In a preferred embodiment as shown in the figures, the mounting hub shaft 30 is comprised of a hollow, cylindrical tube having an upper opening 33 at its upper end 31 and a lower end 32 which is fixedly secured (or integral with) the upper end 21 of the mounting bracket 20. The upper opening 33 in the upper end 31 of the mounting hub shaft 30 leads to an internal channel 34 in which the various components of the adjustment assembly 40 are housed.

[0057] In some embodiments as shown in FIG. 2, the mounting hub shaft 30 includes one or more apertures 35 positioned around its outer circumference adjacent its upper end 31. These apertures 35 may be aligned with corresponding apertures 56 on the collar 50 of the adjustment assembly 40 so that the collar 50 may be secured to the mounting hub shaft 30 via one or more fasteners 36 as best shown in FIGS. 3 and 4.

[0058] ii. Handle Hub.

[0059] As best shown in FIG. 3, a handle hub 60 is included which is rotatably secured to the upper end 31 of the mounting hub shaft 30. The handle hub 60 is rotatable into a plurality of locked positions by utilizing an adjustment assembly 40 as described herein. Preferably, the handle hub 60 will be rotatable such that the handle hub 60 may be locked into approximately 45 degree intervals, though other configurations may be utilized.

[0060] As best shown in FIGS. 3-7, the handle hub 60 is movable longitudinally with respect to the mounting hub shaft 24 preferably without allowing the handle hub 60 to be fully removed from the mounting hub shaft 24. The handle hub 60 is movable from a locked state to an unlocked state, wherein the locked state prevents rotation of the handle hub 60 and wherein the unlocked state allows free rotation of the handle hub 60 about the mounting hub shaft 24. The handle hub 60 is movable in a first longitudinal direction (generally downward) to the locked state and in a second longitudinal direction (generally upward) to the unlocked state to allow free rotation. As described below, the handle hub 60 will preferably be biased toward the locked state such that, absent force, the handle hub 60 will revert back into the locked state.

[0061] The handle hub 60 comprises a base connector 61 and a side support 66 extending from one side of the base connector 61 as best shown in FIG. 2. The base connector 61 comprises a tube member having an upper end 62, a lower opening 63, and an internal cavity 64 extending between the upper end 61 and the lower opening 63. The lower opening 63 is preferably rotatably secured around the upper end 31 of the mounting hub shaft 30 as best shown in FIGS. 3 and 4. The upper handle 70 of the present invention is either fixedly or rotatably secured to the upper end 62 of the base connector 61, depending on the embodiment of the present invention as described herein.

[0062] The side handle support 66 may be comprised of a similar tube-like configuration which is fixedly secured to the outer circumference of the base connector 61 in an orientation such that the base connector 61 and side handle support 66 are perpendicular with respect to each other as shown in the figures. The side handle support 66 includes a first end 67 and a second end 68, wherein the first side handle 80 of the present invention is fixedly secured to the first end 67 of the side handle support 66 and the second side handle 85 of the present invention is fixedly secured to the second end 68 of the side handle support 66.

[0063] iii. Adjustment Assembly.

[0064] The handle hub 60 is rotatable around the upper end 31 of the mounting hub shaft 30 into a plurality of locked positions by utilizing an adjustment assembly 40, which is operable to longitudinally move the handle hub 60 from its locked state to its unlocked state. A variety of adjustment assemblies 40 known in the art to allow a hub to be rotatably locked into a plurality of positions about a rod may be utilized for the present invention.

[0065] In some embodiments, the upper end 31 of the mounting hub shaft 30 or the lower end 63 of the base connector 61 may comprise a tapered collet so as to allow the handle hub 60 to be selectively rotated into a plurality of frictionally-locked positions about the mounting hub shaft 30. Other exemplary adjustment assemblies 40 include a mechanism comprised of mating female and male features which lock at predetermined angles, interlocking teeth on two gears, or any other known rotational locking mechanism. In another embodiment, rotating a threaded collar or threaded clamp would release a collet, thus allowing the handle hub 60 to be rotated about the mounting hub shaft 30. Upon being rotated into the desired position, the threaded collar or threaded clamp could be re-tightened to re-engage the collet and fix the handle hub 60 in position.

[0066] In a preferred embodiment as best illustrated in FIGS. 2-4, the adjustment assembly 40 comprises an anchoring member 41 which is slidably positioned within the inner channel 34 of the mounting hub shaft 30. The anchoring member 41 comprises a circular base portion 42 and an elongated rod portion 43 extending upwardly from the base portion 42 as best illustrated in FIG. 2. The upper end 44 of the anchoring member 41 is fixedly secured within the handle hub 60 such that upward force on the handle hub 60 will draw the anchoring member 41 upwards. The lower end 45 of the anchoring member 41 is left free.

[0067] A bias member 46, preferably comprised of a downwardly-biased coil spring 46 as shown in FIG. 2, is coiled around the rod portion 43 of the anchoring member 41, with the bottom end of the bias member 46 rests or is secured against the base portion 42 of the anchoring member 41 and the top end of the bias member 46 rests or is secured against a lower end 49 of a tube member 47 which similarly extends around the rod portion 43 of the anchoring member 41 at a position above the coil spring 46. The upper end 48 of the tube member 47 rests against the lower end 52 of the collar 50 of the present invention as shown in FIG. 3. The rod portion 43 extends fully through the bias member 46 and tube member 47.

[0068] The collar 50 is utilized to lock the handle hub 60 into a plurality of radial positions with respect to the mounting hub shaft 30. The collar 50 generally comprises a cylindrical structure having an upper end 51 and a lower end 52 which is positioned within the lower opening 63 of the base connector 61 of the handle hub 60.

[0069] The collar 50 includes a plurality of radial protrusions 53 extending outwardly from its outer circumference, preferably adjacent to its upper end 51, which define a plurality of radial slots 54 adapted to matingly engage with a plurality of locking members 65 positioned in the internal cavity 64 of the base connector 61 of the handle hub 60. The rod portion 43 of the anchoring member 41 extends fully through a channel 55 extending through the hollow collar 50, with the upper end 44 of the rod portion 43 being fixed within the handle hub 60.

[0070] The collar 50 includes a plurality of apertures 56 along its outer circumference which are adapted to align with corresponding apertures 35 on the upper end 31 of the mounting hub shaft 30 such that fasteners 36 may be extended therethrough to secure the collar 50 within the upper opening 33 of the mounting hub shaft 30 as shown in FIGS. 3 and 4.

[0071] By applying upward force to the handle hub 60, such as by pulling on one of the handles 70, 80, 85, the base connector 61 of the handle hub 60 will be drawn upward to disengage its internal locking members 65 from the radial slots 54 of the collar 50 and enter an unlocked state. In such an unlocked state with the locking members 65 so disengaged, the handle hub 60 may be freely rotated into a plurality of positions.

[0072] When pulled upward, the bias member 46 will be compressed between base portion 42 of the adjustment assembly 40 and the lower end 49 of the tube member 47 due to the base portion 42 being drawn upward through the hollow tube member 47 and collar 50 as shown in FIG. 4. When such force is released, the downward bias of the bias member 46 will force the anchoring member 41 (and attached handle hub 60) to be drawn back down, and the locking members 65 will re-engage with the radial slots 54, thus locking the handle hub 60 back to a locked state in a new position.

[0073] iv. Handles.

[0074] As shown throughout the figures, the handle assembly 11 of the present invention generally includes an upper handle 70 extending upwardly from the handle hub 60, a first side handle 80 extending in a first side direction from the handle hub 60, and a second side handle 85 extending in a second side direction from the handle hub 60.

[0075] The figure merely illustrate exemplary for the positioning of the first, second and third handles 70, 80, 85 of the present invention. It should be noted that the handles 70, 80, 85 in the figures are generally shown as being locked into a particular configuration. However, the handles 70, 80, 85 may be unlocked, rotated to any desired angle about the mounting hub shaft 30, and re-locked in order to achieve a different handle configuration.

[0076] Each of the handles 70, 80, 85 may be grasped by a person exercising, such as on an exercise machine 90. In some cases, the handles 70, 80, 85 may be used as footrests against which force may be applied through the leg muscles, thereby allowing the person exercising to move the carriage assembly 92 away from the handle end by pushing against the one or more handles 70, 80, 85. The distances between any two of the handles 70, 80, 85 is large enough such that a person may reasonably and comfortably grasp one handle without encountering interference from any other.

[0077] As shown throughout the figures, the first handle 80 comprises a curved, U-shaped configuration and extends in a first direction from the side handle support 66 of the handle hub 60. The proximal end 81 of the first side handle 80 is preferably secured to the side handle support 66. The first side handle 80 curves between its proximal end 81 and its distal end 82. The first side handle 80 comprises a middle handle with respect to the other handles, with its distal end 82 being at an elevation between that of the respective distal ends 87, 74 of the second side and upper handles 85, 70.

[0078] The second side handle 85 similarly comprises a curved, U-shaped configuration and extends in a second direction from the side handle support 66, the second direction being oppositely oriented with respect to the first direction of the first side handle 80. The proximal end 86 of the second side handle 85 is secured to the side handle support 66 on an opposite side with respect to the first side handle 80. The second side handle 85 curves between its proximal end 86 and its distal end 87. The second side handle 85 preferably comprises a lower handle with respect to the other handles, with its distal end 87 being at a lower elevation than that of the respective distal ends 82, 74 of the first side and upper handles 80, 70.

[0079] The upper handle 70 may be comprised of a curved, substantially L-shaped configuration similar to the first and second side handles 80, 85, or, preferably, may be comprised of a right-angle configuration as shown in the figures. In some embodiments, proximal end 72 of the upper handle 70 will be fixedly secured to the upper end 62 of the handle hub 60, such as is shown in FIGS. 1-7.

[0080] In other embodiments, such as shown in FIGS. 8-10, the upper handle 70 may be rotatably locked into a plurality of positions with respect to the handle hub 60. Various adjustment configurations may be utilized for the upper handle 70, including any of those previously disclosed with respect to the rotational locking of the handle hub 60 about the mounting hub shaft 30.

[0081] In a preferred embodiment shown in FIGS. 8-10, the proximal end 72 of the upper handle 70 will include a tapered collet 73 which frictionally engages within the upper end 62 of the base connector 61 when fully pushed in but disengages when pulled out such that the upper handle 70 may be freely rotated before being pushed back in and thus re-engaged in a frictional manner. The distal end 74 of the upper handle 70 preferably extends in a perpendicular direction with respect to the handle hub 60 and is at a higher elevation than that of the respective distal ends 82, 87 of the side handles 80, 85.

C. Exercise Machine

[0082] The handle assemblies 11, 12 of the present invention may be utilized with a wide range of exercise machines 90. FIGS. 11-17 illustrate an exemplary embodiment in use with a Pilates machine 90. The exercise machine 90 shown therein comprises a base 91 with a carriage assembly 92 slidably secured thereon. A person positioned upon the rolling carriage assembly 92, while maintaining their position under the carriage, pushes their hands or feet against one or more of the handles 70, 80, 85 of the handle assemblies 11, 12.

[0083] FIG. 11 illustrates an exemplary diagram showing a Pilates machine 90 with its carriage assembly 92 located in the tensed position, and the approximate location of the handle assemblies 11, 12 thereon. As shown therein, the two handle assemblies 11, 12 are mirror reflections of each other, and are substantially aligned along an X-Axis. However, the handle assemblies 11, 12 need not be mirror images of each other after one or more handles 70, 80, 85 thereof are rotated.

D. Operation of Preferred Embodiment

[0084] FIG. 12 illustrates the carriage assembly 92 in its rested position. A person positioned upon the rolling carriage assembly 92, while maintaining their position upon the carriage 92, pushes their hands or feet against one or more of the handles 70, 80, 85 of the handle assemblies 11, 12, thereby causing the carriage 92 to move along the rails on the exercise machine's 90 base 91 against a spring bias assembly which connects the carriage assembly 92 to the end of the base 91 proximal to the handle assemblies 11, 12.

[0085] FIG. 13 illustrates the carriage assembly 92 of the exercise machine 90, which may include one or more positioning indicia 94 for aiding in various exercises. The positioning indicia 94 may be comprised of numbers which may be referenced by an exercise instructor or manual to aid in a user positioning his/her body on the carriage assembly 92 to more efficiently exercise with the exercise machine 90.

[0086] FIGS. 14-17 illustrate an individual using the present invention. It will become known to one skilled in the art that by rotating the opposed handles 70, 80, 85 inward, and toward each other, a person with narrow shoulders may grab the handles 70, 80, 85 with their hands, more comfortably accommodating the relatively narrow stature of the person, and reducing the possibility of injuring wrist, elbow or shoulder joints that could result from incorrectly aligned anatomy during exercise.

[0087] Similarly, will become obvious to one skilled in the art that by rotating the opposed handles 70, 80, 85 outward, and away each other, a person with wide shoulders may grab the handles 70, 80, 85 with their hands, more comfortably accommodating the relatively broad stature of the person, and reducing the possibility of injuring wrist, elbow or shoulder joints that could result from incorrectly aligned anatomy during exercise.

[0088] FIG. 14 illustrates a person kneeling upon the carriage assembly 92 in a position at the start of an exercise. The hands are positioned closely together to facilitate the increased workload on the triceps muscles of the upper arms, rather than increasing the muscle loading on the trapezius muscles of the upper back and neck. This position also reduces workload on the deltoid muscles of the shoulder in the event that the deltoid muscles have been injured, and a lighter muscle loading is required to promote rehabilitation or reduce the chances of injury.

[0089] FIG. 15 illustrates a person positioned upon the carriage assembly 92 in its working position with the hands being positioned on upper handles 70 being pointed toward each other. By arranging the hands closely together, the person has increased the workload on the triceps muscles by pushing against the handle assemblies 11, 12 of a Pilates apparatus.

[0090] FIG. 16 illustrates a person positioned upon the carriage assembly 92 in its working position with the hands being positioned on the upper handles 70 with the body being raised off of the carriage assembly 92, thereby expending additional muscle energy in the workout compared to a person who did not additionally lift their weight vertically off of the carriage 92. As it will become known to one skilled in the art, the upper handles 70 upon which the illustrative person is holding require more exercise energy output to raise the body higher, than holding handles 80, 85 at a lower position which would have required less work. In other words, by using the upper handles 70, the person has created a more beneficially intense workout than would have been possible using lower-positioned handles.

[0091] FIG. 17 is an exemplary diagram illustrating an orthographic view of a figure of a person positioned upon the rolling carriage 92 located in its working position on a Pilates machine 90. By arranging the hands on handles 70, 80, 85 at different widths and elevations, the person can focus workload on muscles that would not be equivalently worked if the hands were in mirrored positions. As will become known to one skilled in the art, human bodies are not entirely symmetrical, and for health or cosmetic reasons, people desire the ability to work the relatively underdeveloped muscles more than the same muscles on the other side of their bodies in order to more closely balance the asymmetry.

[0092] In this illustration, the person has placed their right hand widely upon the upper handle 70, while placing their left hand more closely to the body, and on a handle 80 that is lower in elevation than the handle used on the right side. It should be noted that, while not shown, any unique combination of handle elevation and hand width can be used in asymmetric combination. It will be readily apparent to one skilled in the art that asymmetric positioning on an exercise device advantageously facilitates the asymmetric workload on muscles, thereby relatively increasing or decreasing workload on the muscles on the right side of the body compared to the same muscles on the left side of the body.

[0093] It should be observed that describing the virtually unlimited combinations of the number of handles 70, 80, 85, handle elevations and the fixed position of those handles 70, 80, 85 relative to each other, the number of handles 70, 80, 85 that can be mounted upon a vertical column and attached to a Pilates apparatus 90, the rotation or adjustment angles of each of those handles 70, 80, 85 for the purpose of exercising different muscles or muscle groups, or to prevent injury would be exhaustive and burdensome. Therefore, it should be noted that the embodiments disclosed are not intended to be limiting, but rather merely illustrate the advantages of the present invention over previous Pilates apparatuses 90 as a result of the novel, and highly flexible design herein disclosed.
