PILATES FITNESS SYSTEM AND METHOD

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to U.S. Provisional Patent Application No.

62/380,276, filed August 26, 2016, which is incorporated herein by reference in its entirety.

FIELD OF THE INVENTION

[0002] The present disclosure relates generally to the field of exercise equipment and more specifically to a Pilates fitness system that is configured to support a user with platforms and to provide resistance to exercise movements by the user in multiple directions and axes of rotation.

BACKGROUND OF THE INVENTION

[0003] Pilates is a type of exercise that focuses on six principles: concentration, control, centering, flow, precision, and breathing. In practice, the Pilates fitness regime relies on controlled exercise movements and positions to increase flexibility and strength. Some of these exercises can be accomplished free standing, without any additional equipment. Body weight exercises are not always possible or practical though. Body weight may not represent the appropriate amount of resistance, and the gravitational force may not be in the appropriate direction for the exercise. Other Pilates exercises can be accomplished with the use of free weights. While the amount of resistive force can be better controlled using free weights, the force is still restricted to a single direction since the exercise relies on the force of gravity.

[0004] A number of devices have been created to facilitate Pilates exercises that are not possible or practical with either body weight or free weights. Some of these machines offer a sliding platform connected to a base, in which the sliding platform slides along a track. The sliding of the sliding platform is resisted by a cable and pulley system coupled to weights, springs, or by an elastic cable causing the platform to resist movement away from a resting position along the single axis of movement. These machines severely limit a user' s range of motion as the sliding platform is restricted to the single axis of movement along the track.

[0005] Thus there is a need for an exercise system that allows a user to use resistance training for various exercises not possible or practical with body weight or free weights, without the system preventing multi-axis and rotational movement by the user. BRIEF SUMMARY OF THE INVENTION

[0006] The present disclosure solves the aforementioned problems of previous devices by providing an improved exercise system that allows a user to experience forces in directions other than the force of gravity that are not restricted to a single axis of movement. The system allows for a wide range of movements within a two-dimensional plane, including rotation around various axes. The system also provides a number of different configurations in which a user can use the system to create both functional integrative holistic exercises and muscle isolation exercises.

[0007] In some embodiments, the fitness system includes a connector, a first user support platform connected to the connector, the first user support platform having a first user support surface; and a second user support platform connected to the connector, the second user support platform having a second user support surface. In such embodiments, the system is configured to extend the second user support platform away from the first user support platform, retract the second user support platform towards the first user support platform, rotate the second user support platform around a first axis orthogonal to and intersecting the first user support surface, and rotate the second user support platform around a second axis orthogonal to and intersecting the second user support surface.

[0008] In some embodiments, a method of using the fitness system includes supporting a first user on a first user support surface of a first user support platform, supporting the first user on a second user support surface of a second user support platform, the second user support platform connected to the first user support platform with a connector, extending the second user support platform away from the first user support platform, retracting the second user support platform towards the first user support platform, rotating the second user support platform around a first axis orthogonal to and intersecting the first user support surface, and rotating the second user support platform around a second axis orthogonal to and intersecting the second user support surface.

[0009] Other objects and features of the present disclosure will become apparent by a review of the specification, claims and appended figures.

DETAILED DESCRIPTION OF THE INVENTION

[0023] The following description sets forth exemplary methods, parameters, and the like. It should be recognized, however, that such description is not intended as a limitation on the scope of the present disclosure but is instead provided as a description of exemplary embodiments.

[0024] The present disclosure is directed to a Pilates fitness system and method of use. The Pilates fitness system includes a system of platforms connected together that a user separates against a resistive force. At least one of the platforms in the system of platforms is movable within a two dimensional plane. The movable platform is also rotatable around multiple axes orthogonal to the two dimensional plane.

[0025] FIG. 1 is a perspective view of one embodiment of a Pilates fitness system in a retracted state. The Pilates fitness system 100 includes a first user support platform 102. In one embodiment the first user support platform is made out of wood. In other embodiments, the first user support platform 102 is made out of any number of materials, including wood, plastic, metal, or any combination of those or other materials. In one embodiment, the first user support platform 102 has a cylindrical shape with a diameter of 27 inches and a height of 3.75 inches. In other embodiments, the first user support platform 102 has a cross section that is triangular, rectangular, pentagonal, hexagonal, or any other shape including free form. Additionally, the first user support platform 102 is one of any number of sizes sufficient to support a user.

[0026] The first user support platform 102 has a top side and a bottom side. In one embodiment, the bottom side of the first user support platform 102 rests on the floor or ground, and the top side includes a first user support surface 104. In some embodiments, the bottom side of the first user support platform 102 includes one or more feet that increase the amount of force required to cause the first user support platform 102 to move with respect to the floor or ground. In some embodiments, the first user support surface 104 is the primary surface of the first user support platform 102 that is in contact with a user during exercise. In some embodiments, contact with the user is through the user' s feet, hands, chest, back, buttocks, or any other body part. In addition, the first user support surface 104 includes one or more of any number of materials or finishes, including wood, plastic, metal, rubber, or any combination of those or other materials. In some embodiments, the finish of the first user support surface 104 provides the characteristics of good traction, easy to clean, and comfortable.

[0027] The Pilates fitness system 100 also includes a second user support platform 106. In some embodiments, the second user support platform 106 is made out of any number of materials, including wood, plastic, metal, or any combination of those or other materials. In one embodiment, the second user support platform 106 has a cylindrical shape with a diameter of 13 inches and a height of 3.75 inches. In other embodiments, the second user support platform 106 includes a cross section that is triangular, rectangular, pentagonal, hexagonal, or any other shape including free form. Additionally, the second user support platform 106 is one of any number of sizes sufficient to support a user. In some

embodiments, the second user support platform 106 is smaller in size than the first user support platform 102 while maintaining the same height. In one embodiment, the first user support platform 102 and the second user support platform 106 are made of the same types of materials.

[0028] The second user support platform 106 has a top side and a bottom side. In one embodiment, the top side includes a second user support surface 108. In some embodiments, the second user support surface 108 is the primary surface of the second user support platform 106 that is in contact with a user during exercise. In some embodiments, contact with the user is through the user's feet, hands, chest, back, buttocks, or any other body part. In addition, the second user support surface 108 is one or more of any number of materials or finishes, including wood, plastic, metal, rubber, or any combination of those or other materials. In some embodiments, the finish of the second user support surface 108 provides the characteristics of good traction, easy to clean, and comfortable. In one embodiment, the first user support surface 104 is the same finish as the second user support surface 108.

[0029] In some embodiments, the second user support platform 106 includes a sliding assembly 110 on the bottom side of the second user support platform 106. The sliding assembly includes any number of various types of systems to minimize friction from movement. For instance, in some embodiments, the sliding assembly 110 includes five individual ball transfers around the perimeter of the bottom side of the second user support platform 106. In another embodiment, the five individual ball transfers are connected to the bottom side of the second user support platform 106 at extensions that extend from the side of the second user support platform 106. In such embodiments, the cross section of the second user support platform 106 resembles a five-pointed star with rounded points, the rounded points each extending outward 1 inch from the second user support platform 106. Other types of sliding assemblies include one or more casters, wheels, drums, tracks, slip surfaces, magnetic levitation, or any other type of mechanism to reduce friction from movement of the second user support platform 106. [0030] In some embodiments, the sliding assembly 110 includes a braking system. The braking system includes a brake that is applied to either the sliding assembly 110 directly or to the floor or ground. The braking system provides a movement resisting force to the second user support platform 106 for movement with respect to the first user support platform 102. In one embodiment, the maximum movement resisting force is sufficient to hold the second user support platform 106 in a single location while in the system 100' s range of operation. In another embodiment, the brake can produce at least 30 pounds of lateral force with respect to the floor or ground. In some embodiments, the braking system is user activated by a mechanical, electrical, magnetic, or pneumatic force, or any other means of generating a force.

[0031] In one embodiment, the first user support platform 102 is connected to the second user support platform 106 with a first connector 112. In some embodiments, the first connector is a flexible material that minimizes any stretching from elasticity, such as nylon. In one embodiment, the length of the first connector is such that when the second user support platform 106 is extended as far as possible away from the first user support platform 102 while the two platforms are connected by the first connector 112, the two platforms are about seven feet apart. In another embodiment, the platforms are connected with the first connector 112 and a second connector 114. The second connector 114 has the same dimensions and is made of the same material as the first connector 112 in some embodiments.

[0032] The first connector 112 has a first end connected to the second user support platform 106 at the first connection point 116. In some embodiments, the first connection point 116 includes a permanent connection point or a detachable connection point. In some embodiments, the first connection point 116 is at a fixed location on the second user support platform 106 or is configurable for placement at more than one location on the second user support platform 106. In some embodiments, the first connection point 116 is on a track on a side wall of the second user support platform 106 that allows the first connection point 116 slides along the track. The second connector 114 has a first end connected to the second user support platform 106 at a second connection point 428. In some embodiments, the second connection point 428 is permanent or detachable, and fixed or movable. The first connection point 116 and the second connection point 428 are on opposite sides of the second user support platform 106 in some embodiments. In one embodiment, the first connector 112 and second connector 114 are in parallel. In another embodiment, a midpoint of a line between the first connection point 116 and the second connection point 428 passes through a center of gravity of the second user support platform 106. In other embodiments, the midpoint does not pass through the center of gravity of the second user support platform 106. In some embodiments, the midpoint of the line between the first connection point 116 and the second connection point 428 is closer to the first user support platform 102 than the center of gravity of the second user support platform 106.

[0033] In some embodiments, the first connector 112 has a second end connected to a first retractor 118. The first retractor 118 maintains a tension force on the first connector 112 as the second user support platform 106 is extended away from, kept in an extended position from, or retracted towards the first user support platform 102. In some embodiments, the first retractor 118 also maintains a tension force on the first connector 112 while the second user support platform 106 is in a retracted state. One example of a retractor is a spool and coil spring mechanism in which the first connector 112 unwinds from the spool and the coil spring loads as the second user support platform 106 extends away from the first user support platform 102. The first connector 112 winds up around the spool and the coil spring unloads as the second user support platform 106 retracts towards the first user support platform 102. In one embodiment, the first retractor 118 is maintains a substantially similar tension force on the first connector 112 between the retracted position and the extended position. In some embodiments, a substantially similar tension force is a force that varies by less than 10% between the retracted position and the extended position. In other embodiments, more or less variation is possible, such as a variation between 0% and 50%.

[0034] In some embodiments, the first retractor 118 includes a tensioner that is used to adjust the tension force on the first connector 112. The tensioner includes two or more discrete tension settings, or a continuously variable setting allowing for a tension setting at any tension setting between a minimum value and a maximum value. In some embodiments, the tensioner setting is controlled with a dial on the first retractor 118 that can be turned to discrete settings that are marked on the dial or on the first retractor 118. In some

embodiments, the tensioner can be adjusted during use, e.g. in the extended state. In one embodiment, the tensioner has a minimum value of three pounds of tension force and a maximum value of fifteen pounds of tension force. In another embodiment, the tensioner has discrete tension settings for three pounds, six pounds, nine pounds, twelve pounds, and fifteen pounds. In one embodiment, the value of force of the tension settings is measured in the extend state. In another embodiment, the value of the force of the tension settings is measured in the retracted state. In yet another embodiment, the value of force of the tension settings is measured between the extended state and the retracted state of the second user support platform 106.

[0035] In some embodiments that include the second connector 114, the second connecter 114 has a second end connected to a second retractor 120. The second retractor 120 maintains a tension force on the second connector 114 as the second user support platform 106 is extended away from, kept in an extended position from, or retracted towards the first user support platform 102. In some embodiments, the second retractor 120 also maintains a tension force on the second connector 114 while the second user support platform 106 is in a retracted state. In other embodiments, the first retractor 118 and the second retractor 120 are a single integrated device. The second retractor 120 is of the same type as the first retractor 118 in some embodiments, but can be any type described above with respect to the first retractor 118.

[0036] In some embodiments, the second retractor 120 includes a tensioner that is used to adjust the tension force on the second connector 114. The tensioner includes two or more discrete tension settings, or a continuously variable setting allowing for a tension setting at any tension setting between a minimum value and a maximum value. In one embodiment, the tensioner has a minimum value of three pounds of tension force and a maximum value of fifteen pounds of tension force. In another embodiment, the tensioner has discrete tension settings for three pounds, six pounds, nine pounds, twelve pounds, and fifteen pounds. In some embodiments, the tensioner in the first retractor 118 is set to a different tension setting than the tension setting of the tensioner in the second retractor 120.

[0037] In some embodiments, one or both of the first retractor 118 and second retractor 120 are attached to the exterior of the first user support platform 102. In other embodiments, one or both of the first retractor 118 and the second retractor 120 are housed inside the first user support platform 102. In this other embodiment, the first connector 1 12 extends out from the first user support platform 102 though a connector opening 122. In some embodiments, the connector opening 122 includes a single small hole in the side of the first user support platform 102 that is only marginally larger than a cross section of the first connector 112. In other embodiments, the connector opening 122 is many times larger than the cross section of the first connector 112. In yet another embodiment, the opening 122 wraps around the entire side wall of the first user support platform 122. The second connector 114 passes through a second connector opening or passes through the connector opening 122 with the first connector 112. In some embodiments, an inside wall of the connector opening 122 is lined with a low friction material. In other embodiments, the inside wall of the connector opening 122 includes bearings, wheels, or some other means for minimizing friction between the first connector 112 and the inside wall of the connector opening 122.

[0038] FIG. 2 is a perspective view of one embodiment of the Pilates fitness system in an extended state. Unlike FIG. 1 which shows the second user support platform 106 in a retracted state, FIG. 2 shows the second user support platform 106 in an extended state. In one embodiment, the first user support platform 102 has remained in the same position as shown in FIG. 1 and the second user support platform 106 has moved relative to the first user support platform 102. To move to the extended state, the first retractor 118 and the second retractor 120 have unwound the first connector 112 and the second connector 114, respectively. As shown in FIG. 2, the first retractor 118 and the second retractor 120 have unwound an equivalent amount such that the distance between the first connection point 116 and the first user support platform 102 is equal to the distance between the second connection point 428 and the first user support platform 102.

[0039] FIG. 3 is a perspective view of one embodiment of the Pilates fitness system in an extended state rotated around a first axis. FIG. 3 shows a first axis 324 that extends through the first user support platform 102 and is orthogonal to the first user support surface 104. The second user support platform 106 has moved from the extended state depicted in FIG. 2 to an extended stated rotated about the first axis 324. In one embodiment, the first user support platform 102 has remained in the same position as shown in FIG. 1 and the second user support platform 106 has moved relative to the first user support platform 102. This rotation is independent of the movement to the extended state as shown in FIG. 2. Alternatively, the rotation and extension can occur in conjunction to provide a single movement along an arc. While FIG. 3 depicts the second user support platform 106 rotating in a counter-clockwise direction from the position depicted in FIG. 2, clockwise rotation is similarly possible.

[0040] As shown in FIG. 3, the second user support platform 106 has maintained its orientation with respect to the first user support platform 102 such that a linear distance between the first connection point 116 and the first retractor 118 equals a linear distance between the second connection point 428 and the second retractor 120. Because the second connector 114 has to wind around a portion of a side wall of the second user support platform 106 in this configuration, a length of the second connector 114 unwound from the second retractor 120 exceeds a length of the first connector 112 unwound from the first retractor 118. Differential tension settings on the first retractor 118 and the second retractor 120 can be used to facilitate this rotation, but is not required.

[0041] FIG. 3 also depicts the connector opening 122 as an opening of sufficient size to allow the first connector 112 and the second connector 114 to track the movement of the second user support platform 106 without having to pivot around an obstructing inner wall of the connector opening 122. In other embodiments, the first connector 112 and/or the second connector 114 contact an inner wall of the connector opening 122 at some angles of rotation around the first axis 324. At the point in which one or both of the connectors contact the inner wall of the connector opening 122, the connector would then cease rotating in a segment between the respective retractor and the connector opening 122. Any additional rotation of the second user support platform 106 around the first axis 324 would cause the respective connector to rotate only in a segment between the connector opening 122 and the second user support platform 106.

[0042] FIG. 4 is a perspective view of one embodiment of the Pilates fitness system in an extended state rotated around a second axis. FIG. 4 shows a second axis 426 that extends through the second user support platform 106 and is orthogonal to the second user support surface 108. In one embodiment, neither the first user support platform 102 not the second user support platform 106 has moved from their position in the extended state as depicted in FIG. 2, but the second user support platform 106 has rotated around the second axis 426 while in place. This rotation is made independent of the movement to the extended state in FIG. 2. Alternatively, the rotation and extension can occur in conjunction to provide a single movement. While FIG. 3 depicts the second user support platform 106 rotating in a counterclockwise direction from the position depicted in FIG. 2, clockwise rotation is similarly possible.

[0043] As shown in FIG. 4, the second user support platform 106 has changed its orientation with respect to the first user support platform 102 such that a linear distance between the first connection point 116 and the first retractor 118 does not equal a linear distance between the second connection point 428 and the second retractor 120. Because the first connector 112 has to wind around a portion of a side wall of the second user support platform 106 in this configuration, a length of the first connector 112 unwound from the first retractor 118 exceeds both a length of the second connector 114 unwound from the second retractor 120 and the linear distance between the first connection point 116 and the first retractor 118. Differential tension settings on the first retractor 118 and the second retractor 120 can be used to facilitate this rotation, but is not required.

[0044] FIG. 5 is a perspective view of one embodiment of the Pilates fitness system with a torque compensator. This embodiment shows Pilates fitness system 500 which is similar to the Pilates fitness system 100. The Pilates fitness system 500 includes a first user support platform 502 and a second user support platform 506, with the second user support platform 506 having a sliding assembly 510. The platforms are connected together with a first connector 512 and a second connector 514. A first end of the first connector 512 and a first end of the second connector 514 are connected to the second user support platform 506 at first connection point 516 and the second connection point, respectively. The embodiment shown in FIG. 5, however, also includes a torque compensator.

[0045] FIG. 5 depicts a single retractor 530 inside the first user support platform 502. The retractor 530 is connected to a torque compensator 532 which is then connected to a second end of the first connector 512 and a second end of the second connector 514. The retractor 530 maintains a tension force in a similar manner as the retractors describe in FIG. 1, however the torque compensator 532 allocates the tension force to the first connector 512 and the second connector 514 equally. For some movements of the second user support platform 506, a length of the first connector 512 between the first connection point 516 and the torque compensator 532 changes with respect to a length of the second connector 514 between the second connection point and the torque compensator 532. The torque compensator 532 causes the tension force on the first connector 512 to remain the same as the tension force on the second connector 514 as the lengths of the two connector segments change with respect to each other. This removes any resistance to a torque force input into the second user support platform 506. In one embodiment, the torque compensator 532 is a sliding mechanism (e.g., a pulley or ring) and the first connector 512 and the second connector 514 are joined as one connector that can rotate around the sliding mechanism.

[0046] In other embodiments, the order of the retractor 530 and the torque compensator 532 is reversed such that the connectors connect to the retractor 530 which then connects to the torque compensator 532. In yet another embodiment, the retractor 530 includes a first retractor and a second retractor, and the torque compensator 532 is feedback system between the two retractors. In some embodiments, the feedback system is electrical, mechanical, or any other type of feedback system. In some embodiments, one or both of the retractor 530 and the torque compensator 532 reside outside the first user support platform 502. [0047] FIG. 6 is a perspective view of one embodiment of the Pilates fitness system with the second platform disconnected from the first platform. This embodiment shows Pilates fitness system 600 which is similar to the Pilates fitness system 100. The Pilates fitness system 600 includes a first user support platform 602 and a second user support platform 606, with the second user support platform 606 having a sliding assembly 610, a first connection point 616 and a second connection point. The first user support platform 602 includes a first retractor 618 connected to a first connector 612 and a second retractor 620 connected to a second connector 614. The embodiment shown in FIG. 6, however, also includes detachable connectors connected to a first end of the first connector 612 and a first end of the second connector 614.

[0048] FIG. 6 shows a first detachable coupling 634 connected to a first end of the first connector 612 and a second detachable coupling 636 connected to a first end of the second connector 614. In one embodiment, the detachable couplings are carabiners. In another embodiment, the detachable couplings are some other means of connection, such as hook and loop, buttons, straps, Velcro, latches, or any other fastening means. In some embodiments, the detachable couplings are made of any number of materials including wood, plastic, metal, or any combination of those or other materials. The detachable couplings are identical, mirror images of one another, or otherwise different from one another. In one embodiment, only one detachable coupling is included. Also, in one embodiment, the detachable couplings 634 and 636 represent only a part of the coupling, with the remainder of the coupling affixed to the second user support platform 606. As is depicted in FIG. 6, some embodiments prevent the first connector 612 from retracting all the way to the retractor 618 after being detached from the second user support platform 606. In some embodiments, this is accomplished by having the detachable coupling 634 exceed the dimensions of the connector opening 622, and thus the detachable coupling 634 gets stopped at the connector opening 622. In other embodiments, the retractor 618 has a stop that removes the tension force from the connector 612 at a certain amount of retraction. And in other embodiments, the detachable coupling 634 is permitted to retract all the way to the retractor 618. Similar configurations can be used with respect to connector 614. With the couplings 634 and 636 detached, the system 600 may be more easily stored, or other optional attachments could be connected to the detachable coupling or couplings.

[0049] FIG. 7 is a perspective view of one embodiment of the Pilates fitness system in a retracted state with handles. This embodiment shows Pilates fitness system 700 which is similar to the Pilates fitness system 100. The Pilates fitness system 700 includes a first user support platform 702 and a second user support platform 706, with the second user support platform 706 having a sliding assembly 710, a first connection point 716 and a second connection point. The first user support platform 702 is connected to a first connector 712 and a second connector 714, which emerge from the first user support platform 702 through a connector opening 722. The embodiment shown in FIG. 7, however, also includes adjustable handles.

[0050] The first user support platform 702 includes a third retractor 738 in addition to the retractor or retractors between the first user support platform 702 and the second user support platform 706. The third retractor maintains a tension force on a third connector 742 that is connected to the third retractor 738 at a first end and to a first handle 744 at a second end. In some embodiments, the third retractor 738 is any type described with respect to the first and second retractors 118 and 120, such as a spool and coil spring mechanism in which the third connector 742 unwinds and the coil spring loads as the first handle 744 extends away from the first user support platform 706. The third connector 712 winds up around the spool and the coil spring unloads as the first handle 744 retracts towards the first user support platform 702. The third retractor 738 is able to maintain a constant tension force on the third connector 742 between a retracted position and an extended position in some embodiments. In one embodiment, at the maximum extension of the third connector the third retractor 738 is about eight feet from the first handle 744.

[0051] In some embodiments, the third retractor 738 includes a tensioner that is used to adjust the tension force on the third connector 742. The tensioner includes two or more discrete tension settings, or a continuously variable setting allowing for a tension setting at any tension setting between a minimum value and a maximum value. In one embodiment, the tensioner has a minimum value of three pounds of tension force and a maximum value of fifteen pounds of tension force. In another embodiment, the tensioner has discrete tension settings for three pounds, six pounds, nine pounds, twelve pounds, and fifteen pounds.

[0052] Some embodiments of the Pilates fitness system 700 permit the third connector 742 to be connected to the first user support platform 702 at any one of a plurality of connection locations on the first user support platform 702. For example, the third connector 742 is connected to the first user support platform 702 by using fasteners placed along the side of the first user support platform 702 in some embodiments. In one embodiment, the third connector 742 is connected to the third retractor 738 which is mounted on a retractor track 740 around a portion of the side of the first user support platform 702. This track allows for the third retractor 738 to be repositioned. In some embodiments, a locking system is provided, and, in one embodiment, the locking system includes a spring-loaded pin that locks the third retractor into one of a number of specific positions with receiving holes. In another embodiment, the locking system includes a braking system that, when engaged, prevents the third retractor 738 from moving while at any position along the retractor track 740. In some embodiments, the third retractor 738 includes a release button that when depressed releases the braking system. Additionally, in another embodiment, the third connector 742 includes a detachable coupling at the first handle 744 that allows the first handle to be removed from the third connector 742. Other optional attachments could then be connected to the third connector 742.

[0053] In some embodiments, the first user support platform 702 includes a fourth retractor. In some embodiments, the fourth retractor is a mirror image of the third retractor 738, and includes a second retractor track, a fourth connector 746 and a second handle 748 connected together. In some embodiments, the fourth retractor is synchronized such that movement of the third retractor 738 along the retractor track 740 causes a mirror movement of the fourth retractor along the second retractor track. In another embodiment, the third retractor 738 and the fourth retractor move along the retractor track 740 and the second retractor track independently.

[0054] FIG. 8 is a perspective view of one embodiment of the Pilates fitness system in an extended state with handles. Unlike FIG. 7, which shows the second user support platform 706 in a retracted state, FIG. 8 shows the second user support platform 706 in an extended state. In this embodiment the handles are also in an extended state. In one embodiment, the first user support platform 702 has remained in the same position as shown in FIG. 7 and the second user support platform 706 has moved relative to the first user support platform 702. For the handles to move to the extended state, the third retractor 738 and the fourth retractor have unwound the third connector 742 and the fourth connector 744, respectively. The handles are depicted having moved an equal amount with respect to each other, but in other embodiments they move independently of one another.

[0055] FIG. 9 is a perspective view of one embodiment of the Pilates fitness system in a retracted state with handles in an alternate position. Unlike FIG. 7, which shows the third retractor 738 in a first location along the retractor track 740, FIG. 9 depicts one embodiment in which the third retractor 738 is moved to a second location along the retractor track 740 and locked into position at the second location. In addition, FIG. 9 shows that the first handle 744 has been extended away from the first user support platform 702 in an alternate direction from the direction depicted in FIG. 8. In some embodiments, the first handle 744 extends in any direction away from the third retractor 738, while the third connector 742 remains under tension. The second handle 748, fourth connector 746, and the fourth retractor function similarly to the first handle 744, third connector 742, and the third retractor 738.

[0056] FIG. 10 is a perspective view of one embodiment of the Pilates fitness system in an extended state with a footboard engaged. This embodiment shows Pilates fitness system 1000 which is similar to the Pilates fitness system 100. The Pilates fitness system 1000 includes a first user support platform 1002 having a first user support surface 1004 and a second user support platform 1006 having a second user support surface 1008. The second user support platform 1006 includes a sliding assembly 1010, a first connection point 1016 and a second connection point. The first user support platform 1002 includes a first retractor 1018 connected to a first connector 1012 and a second retractor 1020 connected to a second connector 1014. The first connector 1012 exits the first user support platform 1002 at connector opening 1022. The embodiment shown in FIG. 10, however, also includes a hinging footboard.

[0057] The footboard 1050 is a platform that moves with respect to the first user support platform 1002. In some embodiments, the footboard 1050 moves to one or more alternate angles from the first user support platform 1002. For example, FIG. 10 depicts the footboard 1050 set at 90 degrees from the first user support platform 1002. In this configuration a user can brace against the footboard 1050 while extending the second user support platform 1006. The footboard 1050 is made of made out of any number of materials, including wood, plastic, metal, or any combination of those or other materials. In one embodiment, the footboard 1050 and the first user support platform 1002 are made out of the same materials.

[0058] The footboard 1050 is connected to the first user support platform 1002 at a hinge 1052. The hinge 1052 is any number of different types of hinges, including a barrel, pivot, mortise, butterfly, flag, strap, floating and living hinge. In some embodiments, the hinge 1052 is a single integrated device or includes multiple separate hinges. In one embodiment, the position of the footboard 1050 is determined by the rotation of the hinge 1052, and the footboard 1050 is locked into a position using a locking mechanism. The locking mechanism is able to resist a force as least as great as the sum of the forces generated from the retractors. In one embodiment, the locking mechanism is integral to the hinge 1052, and a user engages and disengages the lock on the hinge. In another embodiment, the locking mechanism is separate from the hinge 1052, such as a folding brace, and the user engages and disengages the lock separate from the hinge. In another embodiment, the lock automatically engages when the footboard 1050 is moved to a predefined position. In other embodiments, the locking mechanism allows for multiple locked positions.

[0059] The footboard 1050 has a third user support surface 1054. In some embodiments, one or both of the first user support surface 1004 and the third user support surface 1054 are the primary surface of the first user support platform 1002 that is in contact with a user during exercise. In some embodiments, contact with the user is through the user's feet, hands, chest back, buttocks, or any other body part. In addition, the third user support surface 1054 includes any number of materials or finishes, including wood, plastic, metal, rubber, or any combination of those or other materials. In one embodiment, the third user support surface 1054 has the same finish as the first user support surface 1004. In some

embodiments, the finish of the third user support surface 1054 provides the characteristics of good traction, easy to clean, and comfortable.

[0060] In one configuration of the footboard 1050, the third user support surface 1054 is approximately coplanar with the first user support surface 1004. In this configuration the third user support surface 1054 supports a user similar to the first user support surface 1004. In some embodiments, the third user support surface is locked place while in this position, or is held in place by the force of gravity. In a second configuration the footboard 1050 is moved into a second position by being rotated around the hinge 1052 and locked into place. In this second configuration the third user support surface 1054 is not approximately coplanar with the first user support surface 1004. In one embodiment, the second position of the footboard 1050 maintains the third user support surface 1054 at an angle between 30 degrees and 150 degrees from the first user support surface 1004. In another embodiment, the second position of the footboard 1050 maintains the third user support surface 1054 at an angle of 90 degrees from the first user support surface 1004.

[0061] In one embodiment, the footboard 1050 is rotatable around the hinge 1052 to expose an open cavity inside the first users support platform 1002. The open cavity in the first user support platform 1002 is used for storage and/or to house any device attached to the first user support platform 1002. For example, in some embodiments, the first retractor 1018 is housed inside the cavity in the first user support platform 1002. In this embodiment, a tensioner on the retractor is adjusted by the user moving the footboard to gain access to the open cavity, and manipulating a tension setting of the tensioner on the first retractor 1018. In other embodiments, a detachable coupler between the first retractor 1018 and the first connector 1012 is accessed by moving the footboard 1050 to expose the open cavity.

[0062] FIG. 11 is a perspective view of one embodiment of the second platform with a seat. This embodiment shows a second user support platform 1106 which is similar to the second user support platform 106. The second user support platform 1106 has a second user support surface 1108. The second user support platform 1106 includes a sliding assembly 1110, a first connection point 1116 and a second connection point. The second user support platform 1106 is connected to a first connector 1112 at the first connection point 1116 and connected to a second connector 1114 at the second connection point. The embodiment shown in FIG. 11, however, also includes a seat.

[0063] The seat 1156 works in conjunction with one of the support platforms, and, in one embodiment, covers the second user support surface 1108 of the second user support platform 1106 to provide an alternate user support surface. In some embodiments, the seat 1156 is used with the embodiment depicted in FIG. 10, but that is not required. In one embodiment, the seat 1156 has a footprint similar to the second user support platform 1106 or the second user support surface 1108. In other embodiments, the footprint of the seat 1156 is dissimilar to a footprint of the second user support platform 1106 or the second user support surface 1108. The seat is made of wood, plastic, metal, rubber, cushioning or any other material or combination of materials.

[0064] In one embodiment, the seat 1156 includes a seat back 1158. The seat back 1158 is attached to an end of the seat 1156 that is farthest from a first user support platform in some embodiments. In one embodiment, the seat back 1158 is integrally joined to the seat 1156, while in other embodiments the seat back 1158 is removable from the seat. In other embodiments, the seat 1156 includes only the seat back 1158 connected to the second user support platform 1106. In some embodiments, the seat back 1158 is made from similar materials as to those described for the seat 1156.

[0065] The seat 1156 has a fourth user support surface 1160 and a fifth user support surface 1162. The fourth user support surface 1160 is not coplanar with the fifth user support surface 1162. In some embodiments, the fourth user support surface 1160 is parallel to the second user support surface 1108. In one embodiment, the seat back 1158 maintains the fifth user support surface 1162 at an angle between 15 degrees and 165 degrees from the fourth user support surface 1160. In some embodiments, the fourth user support surface 1160 and the fifth user support surface 1162 are the primary surfaces of the second user support platform 1106 that are in contact with a user during exercise. In some embodiments, contact with the user is through the user's feet, hands, chest, back, buttocks, or any other body part. In some embodiments, the fourth user support surface 1160 is in contact with a user' s buttocks and the fifth user support surface 1162 is in contact with a user's back. In addition, the fourth user support surface 1160 and the fifth user support surface 1162 is any number of materials or finishes, including wood, plastic, metal, rubber, or any combination of those or other materials. In one embodiment, the finish of the fourth user support surface 1160 and the fifth user support surface 1162 provide the characteristics of good traction, easy to clean, and comfortable.

[0066] The seat 1156 includes a position lock 1164. In one embodiment, the position lock 1164 includes a peg that protrudes from the bottom of the seat 1156 and is received in the first position lock receiver 1166. In another embodiment, the position lock 1164 includes a first peg and a second peg that protrude from the bottom of the seat 1156 and are received in the first position lock receiver 1166 and the second position lock receiver 1 168, respectively. In these configurations the force of gravity maintains the coupling of the position lock 1164 to the position lock receivers 1166 and 1168 such that any forces generated by the user are transferred through the seat 1156 to the second user support platform 1106, causing the second user support platform 1106 to move or hold position. In other embodiments, the position lock 1164 is a high friction surface that when placed in contact with the second user support surface 1108, couples the seat 1156 to the second user support platform 1106. In other embodiments, the position lock 1164 and position lock receivers 1166 and 1168 are any known coupling device, such as hook and loop, buttons, straps, Velcro, latches or any other fastening or securing means.

[0067] FIG. 12 is a flow chart representing a method of use of the Pilates fitness system, according to one embodiment. The method of use shown in process 1200 may be used with any one of the embodiments discussed above, or independent of any previously discussed embodiments.

[0068] At block 1202 the method describes supporting a user. In some embodiments, the user is any person seeking fitness or therapeutic benefits. The user is supported by a first surface of a first user support platform by placing some of their weight on the first user support surface of the first user support platform. In one embodiment, the user is supported by placing one of their feet on the first user support surface.

[0069] At block 1204 the method describes supporting the user with a second user support surface of a second user support platform by placing some of their weight on the second user support surface. In one embodiment, the user is supported by placing one of their feet on the second user support surface. In one embodiment, the user is supported by the first user support surface and the second user support surface simultaneously. In block 1204, the second user support platform is also described as connected to the first user support platform by a connector. The connector is any one of the types of connectors discussed previously, and, in one embodiment, is of the type of connector described with respect to FIG. 1. As discussed above with respect to FIG. 1, the connector optionally includes detachable couplers that enable the user to disconnect the first user support platform from the second user support platform and also to reconnect the first user support platform to the second user support platform.

[0070] At block 1206 the method describes extending the second user support platform away from the first user support platform. This extension is controlled by the user in one embodiment. In some embodiment, the user adds a radial force from the first user support platform to overcome a resistive force in the connector between the two user support platforms. A sufficient radial force causes the second user support platform to move away from the first user support platform. In one embodiment, the radial force is generated by the user placing a first foot on the first user support surface and a second foot on the second user support surface and inputting opposing forces into the platforms through their feet.

[0071] In other embodiments, the first user platform has a footboard with a third user support surface, similar to the embodiment shown in FIG. 10. In this embodiment, the third user support surface is not approximately coplanar with the first user support surface and the footboard maintains the third user support surface at an angle between 30 degrees and 150 degrees from the first user support surface. In another embodiment, the footboard maintains the third user support surface at an angle of 90 degrees from the first user support surface. Additionally, in this embodiment, the second user support platform includes a seat, similar to the embodiment shown in FIG. 11. The seat provides a fourth user support surface and a seat back with a fifth user support surface. In this embodiment, a user places one or both feet on the third user support platform and sits on the fourth user support platform with their back against the fifth user support platform. The user is then able to extend their legs to impart a radial force on the second user support platform.

[0072] In some embodiments, the amount of resistive force from the connector is controlled by an adjustable tensioner that imparts a tension force into the connector between the two user support platforms. In one embodiment, the adjustable tensioner is set by the user to a range of tension values. The range of tension values, in one embodiment, ranges from three pounds to fifteen pounds of tension force in each connector used.

[0073] At block 1208 the method describes retracting the second user support platform towards the first user support platform. The retraction is controlled by the user in one embodiment. In some embodiments, the user subtracts all or part of a previously applied radial force to the second user support platform to cause it to move towards the first user support platform under the resistive force in the connector between the two user support platforms.

[0074] At block 1210 the method describes rotating the second user support platform around a first axis. The first axis is defined as orthogonal to and intersecting the first user support surface. The rotation around the first axis is similar to the rotation depicted in FIG. 3 in which the second user support platform follows a portion of an orbit around the first axis. In one embodiment, this movement is controlled by the user. In some embodiments, the user provides two forces. The user maintains a previously applied radial force to the second user support platform to cause it to maintain the distance from the first user support platform. Simultaneously the user adds a force tangential to the portion of the orbit around the first user support platform to induce a rotation of the second user support around the first axis.

[0075] In other embodiments, the connector between the first user support platform and the second user support platform includes a first connector and a second connector connected to a first tensioner and a second tensioner, respectively. In this embodiment, the first and second tensioners can be set to differential tension settings to induce rotation around the first axis, which can be counteracted by an opposing force generated by the user to hold the second user support platform in place.

[0076] At block 1212 the method describes rotating the second user support platform around a second axis. The second axis is defined as orthogonal to and intersecting the second user support surface. The rotation around the second axis is similar to the rotation depicted in FIG. 4 in which the second user support platform rotates in place. In one embodiment, this movement is controlled by the user. In some embodiments, the user provides two forces. The user maintains a previously applied radial force to the second user support platform to cause it to maintain the distance from the first user support platform. Simultaneously the user adds a torque force to induce a rotation of the second user support around the second axis.

[0077] In other embodiments, the connection between the first user support platform and the second user support platform includes a first connector and a second connector connected to a first tensioner and a second tensioner, respectively. In this embodiment, the first and second tensioners can be set to differential tension settings to induce rotation around the second axis, which can be counteracted by an opposing force generated by the user to hold the second user support platform in place.

[0078] The process 1200 may be performed in any order and each block may be performed sequentially or in parallel with any other block or blocks. For example, in one embodiment, block 1210 and block 1212 are performed simultaneously such the second user support platform is rotated around both the first axis and the second axis at the same time. Similarly, in another embodiment, block 1206 and block 1210 are performed simultaneously such that the second user support platform travels along an arc. In other embodiments some or all of the blocks are performed serially. As an example, in one embodiment, the second user support platform rotates around a second axis, but the second axis is held in a fixed position without the second user support platform extending, retracting, or rotating around the first axis.

[0079] The foregoing description is presented to enable a person of ordinary skill in the art to make and use the various embodiments. Descriptions of specific systems, devices, techniques, and applications are provided only as examples. Various modifications to the examples described herein will be readily apparent to those of ordinary skill in the art, and the general principles defined herein may be applied to other examples and applications without departing from the spirit and scope of the various embodiments.
