    DETAILED DESCRIPTION

    (11) The present invention mitigates and/or obviates the disadvantages of typical tilting inversion exercisers by properly aligning the ankles of a user with the hip of a user, allowing the torso of a user to slide independently of the pelvis of a user and allowing a user to user to assume an inclined posture. The present invention effectively mitigates and/or obviates the excessive extension forces common to typical tilting inversion exercisers, and allows a user to achieve a neutral spinal alignment with increased traction and greatly reduced rotational pressures.

    (12) As disclosed in the present invention, the torso section/torso sled of the supporting table must slide independently of the fixed pelvic section of the supporting table to mitigate excessive extension forces common to tilting inversion exercisers and facilitate traction.

    (13) As disclosed in this invention, on a tilting inversion exerciser the torso section/torso sled of the supporting table must move or slide independently of the secured pelvic section to maximize the effects of gravity during inversion and to facilitate neutral spinal alignment.

    (14) As disclosed in the present invention, the complete foot ankle restraint device, including the back pads, must be able to move or adjust in a linear direction relative to a user and the supporting table to align the center of the ankle of a user with the hip of user.

    (15) As disclosed in the present invention, the torso of a user must be supported in an inclined posture to mitigate extension forces common to typical tilting inversion exercisers.

    (16) Furthermore, as disclosed in the present invention, the torso section/torso sled of the supporting table must slide independently of the secured pelvic section of the supporting table to mitigate excessive extension forces common to typical tilting inversion exercisers.

    (17) The following detailed description is exemplary in nature and is in no way intended to limit the scope of the invention, its application, or uses, which may vary. The invention is described with relation to the non-limiting definitions and terminology included herein. These definitions and terminology are not designed to function as a limitation on the scope or practice of the invention, but are presented for illustrative and descriptive purposes only.

    (18) Sliding Torso Section/Torso Sled

    (19) One aspect of the present invention is to provide for support tables which allow the torso section/torso sled of the supporting table and torso of a user to slide longitudinally independent of the fixed pelvic section of the supporting table and pelvis of a user.

    (20) The primary means to produce a dynamic flexion moment on a tilting inversion exerciser to maximize traction and allow for neutral spinal alignment during inversion is to facilitate the torso of a user sliding independently of the fixed pelvis of a user on the supporting table.

    (21) In at least one embodiment inventive tilting inversion exercisers having a sliding torso section/torso sled of the supporting table are provided. In at least one embodiment an inventive independent sliding torso section, or torso sled, of the supporting table includes at least one posterior hollow metal sled beam being square or cylindrical, one low friction liner or sleeve being square or cylindrical, at least one central beam extension being square or cylindrical, at least one posterior excursion channel, one or more central beam excursion limiters, and one or more sled motion stops.

    (22) Embodiment of the invention the torso sled provides a means to facilitate sliding of the torso section/torso sled of the supporting table independent of the fixed pelvic section of the supporting table and pelvis of a user. Without being bound to a particular theory, it is believed that the independent sliding of the torso of a user allows a more neutral spine to be achieved during inversion than on typical tilting inversion exercisers. It is further believed that the independent sliding of the torso of a user on the supporting table also mitigates pressure on the pelvis during inversion common to tilting inversion exercisers and facilitates earlier and greater traction than is common to typical tilting inversion exercisers.

    (23) It should be appreciated that in certain embodiments the torso sled extends as a separate moveable plate from just above the fixed pelvic section plate of the supporting table which is securely fastened to the frame. In such embodiments, as a user begins to invert, longitudinal excursion of the torso sled on the central beam of the frame creates a gentle rotation of the torso to counter the excessive extension forces common to typical tilting inversion exercisers. At the point at which excessive pressure against the pelvis of the user from the supporting table would occur on typical tilting inversion exercisers, it is mitigated by longitudinal linear sliding and excursion of the torso sled on the central beam of the frame. This excursion of the sled facilitates earlier and greater spinal traction and allows the spine of the user to assume a more neutral alignment than is common to typical tilting inversion exercisers. In this embodiment torso sled range of motion is determined by the length of the posterior excursion channel and the position of the excursion limiter on the posterior aspect of the central beam. Torso sled motion can be blocked prior to inversion in this embodiment by engaging one or more sled motion stops.

    (24) In at least one embodiment an alternative design to facilitate sliding of the torso sled section plate of the supporting table independent of the secured pelvic section plate of the supporting table is provided. In such embodiments, an inventive sliding torso sled includes at least one posterior metal central beam outrigger, at least one central beam rail or slot, at least one metal posterior torso sled torso plate, at least two posterior torso sled wheels, at least two excursion blocks, and at least one sled locking mechanism. Embodiment of the invention provides a means to facilitate longitudinal sliding of the torso sled, independent of the fixed pelvic section, on wheels attached to the torso sled moving in tracks or slots secured to outriggers extending from the central beam of the frame. Materials in this embodiment used to facilitate motion between the torso sled and central beam outriggers include, but are not limited to bearings, low friction plastic, Teflon, and other low friction materials. In this embodiment the torso section/torso sled is allowed unrestricted longitudinal translational movement within a secure range of motion of the torso sled. Movement of the torso sled can be blocked by tightening locking mechanisms on the carrier frame and/or supporting table prior to inversion.

    (25) In another embodiment inventive tilting inversion exercisers having a sliding torso section/torso sled of the supporting table are provided. In at least one embodiment, an inventive sliding support table includes at least one slide plate 115, at least one posterior plate 116, and one or more 117 fasteners for connecting the at least one 116 posterior plate to the at least one 115 slide plate through the 110 torso section/torso sled of the supporting table. In such embodiments, the at least one posterior plate is beneath the at least one torso sled, the at least one slide plate is atop the at least one torso sled, and the one or more fasteners connect the at least one posterior plate to the at least one slide plate through the at least one torso sled. In at least one embodiment, it is intended that the slide plate is capable of moving independently from the other elements of the supporting table.

    (26) It should be appreciated that in certain embodiments of the present invention, the at least one slide plate, at least one torso sled or at least one posterior plate have a plurality of holes for receiving one or more fasteners. It should be further appreciated that holes implemented into the individual components may be slotted or elongated to allow the slide plate to move several inches about said one or more fasteners.

    (27) In embodiments of the invention the slide plate provides a means to facilitate sliding of the torso of a user independent of the pelvic section of the supporting table and pelvis of a user. Without being bound to a particular theory, it is believed that the independent sliding of the torso of a user allows a more neutral spine to be achieved during inversion than on typical tilting inversion exercisers. It is further believed that the independent sliding of the torso of a user on the supporting table also mitigates pressure on the pelvis common to typical tilting inversion exercisers and facilitates earlier and greater traction than is common to typical tilting inversion exercisers. The assembly of plates of embodiments presented herein, are intended to be attached to at least one supporting table. In at least one embodiment the supporting table is made of plastic or other low friction synthetic material.

    (28) In certain embodiments, the slide plate may be connected to a plate, or plates, of plastic or other low friction synthetic material on the back of the supporting table through a series of elongated slots in the supporting table. In certain embodiments, it is intended that the plastic plate, or plates, are secured to the back of the supporting table and have slots which mirror those in the supporting table.

    (29) In some embodiments, one or more rigid fasteners are used extend from the top surface of the slide plate and connect through to the back of the supporting table. In at least one embodiment the fasteners are threaded locking mechanisms with low friction washers which allow for surfaces to move freely on the surface of the plastic plate. In embodiments with slotted holes, the one or more fasteners move freely in the slots in the supporting table and back plate, allowing unrestricted longitudinal excursion of the slide plate on the torso section/torso sled of the supporting table.

    (30) It should be appreciated that in certain embodiments, the slide plate extends from just above the pelvis of a user to the top of the supporting table. In such embodiments, as a user begins to invert, excursion of the slide plate proximally in the slots creates a gentle rotation of the torso in the direction of flexion to counter the excessive rotation forces in the direction of extension. At the point at which pressure against the pelvis from the supporting table would normally occur on a typical tilting inversion exerciser, it is mitigated by proximal linear excursion of the slide on the supporting table. The slide plate responds to gravity and rotational pressure. As a user returns to the starting position, gravity will cause the slide plate to return to the original bottom position in the slots in the supporting table. Handles or loops attached to the top of the slide plate allow a user to manually increase traction by pulling the slide plate proximally to increase excursion of the slide plate in the slots. Motion of the slide plate can be blocked by tightening the locking mechanisms on the back of the supporting table prior to inversion.

    (31) In at least one embodiment, the slide plate is a sheet of high molecular weight plastic or other low friction plastic or synthetic material that slides on the surface of the torso section/torso sled of the supporting table. However, it should be appreciated that embodiments of the invention, the surface of the slide plate and/or supporting table may incorporate other low friction materials to facilitate linear motion between the slide plate and the supporting table including, but not limited to Teflon, balls, bearings, rotary objects, rails or other low friction materials or objects.

    (32) Embodiments of the present invention provide for an independent plate which supports the head and neck of a user. In such embodiments, the independent plate is made of high molecular weight plastic or other low friction plastic or synthetic material, and is connected to the slide plate with fasteners which extend from the bottom surface of the slide plate through elongated slots in the head and neck plate. It is intended that the plate supporting the head and neck of a user is able to move independently of the slide plate and supporting table and slide longitudinally on the surface of the slide plate by excursion of the fasteners in the slots. The head and neck plate facilitates gentle traction of the cervical spine during inversion.

    (33) In embodiments where a separate torso section/torso sled is allowed to slide on the carrier frame, independent of a fixed pelvic section, the plate supporting the head and neck of a user is attached directly to the supporting table with fasteners through elongated slots in the supporting table. In such embodiments, the plate is able to slide independently on the surface of the torso section/torso sled of the supporting table by excursion of the fasteners in the slots in the torso section/torso sled of the supporting table.

    (34) Ankle Alignment System

    (35) One aspect of the present invention is to mitigate/obviate posterior ankle center malalignment common in typical tilting inversion exercisers which facilitates excessive extension of the body during inversion. Embodiments of the invention solves the problem of ankle malalignment with an adjustable ankle alignment system that allows the complete foot restraint device to be incrementally adjusted linearly and perpendicular relative to a user and the supporting table to align the center of the ankle of a user with the center of the hip of a user.

    (36) In at least one embodiment an adjustable ankle alignment system for a tilting inversion exerciser is provided which allows for linear adjustments of ankle center of a user relative to hip center of a user. Such embodiments include at least one height adjustment beam, at least one adjustment beam offset strut having one or more holes for receiving one or more struts of a vertical foot restraint strut, at least one vertical restraint strut having one or more projections, and at least one foot restraint device. In such embodiments, the height adjustment beam is connected to one end of the adjustment beam offset strut and the one or more vertical foot restraint strut projections are inserted into one or more holes of said adjustment beam offset strut. The foot restraint device is connected to said at least one vertical foot restraint strut. It should be appreciated that one or more tightening mechanisms for fastening the vertical foot restraint strut projections to the adjustment beam offset strut. In at least one embodiment the vertical foot restraint strut is threaded, while in other embodiments the vertical restraint strut is unthreaded.

    (37) Embodiments of the invention, the complete foot restraint device is secured to the vertical foot restraint strut, and moves linear and perpendicular to the longitudinal height adjustment beam and supporting table. In at least one embodiment, welded projections (or projection) from the vertical foot restraint strut slide through openings (or opening) in the adjustment beam offset strut which is welded parallel to the posterior aspect of the shortened longitudinal height adjustment beam. In such embodiments, channels welded to the extension offset strut receive the projections from the vertical foot restraint strut. In such embodiments, pressure tightening mechanisms secure the projections from the vertical foot restraint strut in the channels of the adjustment beam offset strut. When the vertical foot restraint strut is tightened flush against the adjustment beam offset strut, the position of the complete foot restraint device relative to the supporting table mimics the typical tilting inversion exerciser. From this initial flush position, the vertical restraint strut, which secures the foot restraint device, can be slid or adjusted incrementally in a linear direction relative to the supporting table to align the center of the ankle of a user with the hip of a user. It should be appreciated that the projections from the vertical foot restraint strut may be incrementally moved in and out of the openings in the offset strut utilizing, but not limited to, a ratchet mechanism on the projections from the vertical restraint strut common to a drill press or other machinery. Furthermore, it should be appreciated that the adjustment knobs or handles used to engage the ratchet mechanism on the projections from the vertical restraint strut are incorporated into the adjustment beam offset strut. Brackets attached to the offset strut may be substituted for openings in the offset strut to receive projections from the vertical foot restraint strut in certain embodiments

    (38) At least one embodiment of the present invention provides springs and hinge to obviate/mitigate ankle center malalignment and absorb changing rotational forces during inversion to reduce pressure on the ankles of the user. In at least one embodiment, at least two springs each with welded plates on either end are attached to opposing ends of the vertical foot restraint strut. In such embodiment, the springs on opposing ends of the vertical foot restraint strut are attached to the offset strut or main height adjustment beam via the plates on the end of each spring sliding into corresponding spring retaining slots on the offset strut or main height adjustment beam. Hinge struts with pivot holes proceeding from the offset strut are secured to the foot restraint strut with a hinge pin. This inventive hinge and spring embodiment improves ankle alignment and adapts to the varying rotational pressures during inversion, reducing foot and ankle pressure common with typical inversion exercisers.

    (39) Embodiments of the present invention, the back pads of the foot restraint device are no longer secured or confined to the longitudinal height adjustment beam, as is the case on all typical tilting inversion exercisers. The capability to slide the complete foot restraint device linearly relative to the supporting table in the present invention ensures that the center of the ankle of a user can be aligned with the hip of the user regardless of the size of the user.

    (40) Without being bound to a particular theory, it is believed that proper ankle-hip alignment during inversion allows traction forces to be centered through the joints of a user. Thus it is further believed that proper alignment minimizes rotational pressure on the feet and ankles during inversion and decreases stress on the knees. Thus the proper ankle-hip alignment facilitates traction and reduces excessive extension forces that excessively extend or arch the lumbar spine. Accordingly, it is further believed that incremental linear movements of the foot restraint device, and therefore ankle center, have a significant impact on flexion-extension forces at the lumbar spine. The capability to influence spinal alignment by incremental linear movements of the foot restraint device is a significant contribution of the present invention to tilting inversion exerciser therapy.

    (41) In at least one embodiment, the adjustable ankle alignment allows the projections of the vertical foot restraint strut, which secures the entire foot restraint device, to slide directly through openings in the longitudinal height adjustment beam, omitting the offset extension strut. In such embodiments, the aforementioned ratchet system may be utilized, or any other means to facilitate incremental linear movement of the projections of the vertical foot restraint strut through the openings in the longitudinal height adjustment beam to align the center of the ankle of a user with the center of the hip of a user.

    (42) Some embodiments of the present invention provide a static adjustable ankle alignment adjustable ankle alignment design to mitigate/obviate posterior ankle center malalignment common to typical tilting inversion exercisers. In such embodiments, the projections from the vertical foot restraint strut, which secures the complete foot restraint device, slide directly through openings in the longitudinal height adjustment beam, omitting the offset extension strut. In such embodiments, the projections from the vertical foot restraint strut include threaded ends which extend through the openings in the longitudinal height adjustment beam, allowing the vertical restraint strut to rest flush against the longitudinal height adjustment beam, positioning the foot restraint device slightly anterior relative to the supporting table. In at least one embodiment, additional spacers can be added, as needed, between the vertical foot restraint strut and the longitudinal height adjustment beam in order to position the foot restraint device more anterior relative to the supporting table and user in order to achieve the desired ankle center of a user relative to the hip center of a user. In at least one embodiment, locking mechanisms on the posterior side of the longitudinal height adjustment beam engage the threaded projections from the vertical restraint strut and are tightened to secure the foot restraint device once the desired ankle position is achieved.

    (43) Torso Wedge

    (44) Embodiments of the invention include restraining devices to positive engage the torso and pelvic section of the supporting table to the torso and pelvis of a user. Examples of suitable restraining devices include bands, straps, friction tape, adhesive, or other friction increasing materials known in the art.

    (45) Other aspects of the present invention solve the problem of supporting the torso of a user in an angle of inclination. In at least one embodiment, an inventive dual plane torso wedge is implemented with inventive tilting inversion exercisers in to facilitate maintaining the torso of a user in an angle of inclination during inversion.

    (46) Embodiments of the torso wedge provide for an inclined or semi-inclined irregular shaped wedge of foam, rubber or other compressive material that can be attached to the slide plate by a number of projections on the bottom of the wedge which engage slots and/or holes in the slide plate, or independent sliding torso section/torso sled of the supporting table. In at least one embodiment, the torso wedge utilizes Velcro or other attachment materials for engagement with the slide plate, or independent sliding torso section/torso sled of the supporting table. It should be appreciated, that when used, the wedge can be moved as necessary on the slide plate, or independent sliding torso section/torso sled of the supporting table, to adjust to the height of a user.

    (47) In at least one embodiment, the torso wedge is narrower than the slide plate and torso sled, approximating the width between the scapula, to facilitate active rotary mobility of the spine during inversion, if desired, as well as to open the chest and position the shoulders in more optimal alignment. In at least one embodiment, the wedge is thicker at the top than the bottom, and beginning at neck level of a user, the torso wedge is approximately parallel to the supporting table and contoured to cradle the neck of a user in order to support the head and neck of a user near neutral alignment.

    (48) Certain embodiments of the inventive torso wedge acts as a lever to enhance function of the slide plate. As a user begins to invert, pressure against the torso wedge is transferred to the slide plate, dynamically activating the slide.

    (49) In embodiments where the torso sled slides independently on the carrier frame, the torso wedge dynamically activates the torso sled-section/torso sled of the supporting table, rather than the slide plate.

    (50) It is believed that the dynamic flexion moment created by the torso of a user positioned on a wedge during inversion creates an effective counterforce to the persistent dynamic extension forces common to typical tilting inversion exercisers which prohibit neutral spinal alignment during inversion. Accordingly it is believed that embodiments of the torso wedge effectively neutralize the strong extension forces created when a user raises the arms overhead during inversion and mitigates, in conjunction with independent sliding of the torso, excessive ribcage elevation during inversion common to typical tilting inversion exercisers. As a result, there is less compression on the diaphragm during inversion, and the compromised breathing during inversion common to typical tilting inversion exercisers is mitigated. It is further believed that the torso wedge provides proprioceptive feedback to a user. Accordingly, in embodiments where used, the support of the wedge gives a user greater initial sensory feedback during inversion which provides a sense of security for a user and enhances user control of the rate of inversion.

    (51) It is believed that use of a torso wedge alone on common tilting inversion exercisers results in an increase in friction and loss of traction during inversion. However, when the torso wedge is used in conjunction with the sliding torso embodiments and adjustable ankle systems, as disclosed herein, it facilitates rather than inhibits traction by acting as a lever to activate the torso sled or slide plate.
