Illustrative embodiments of the invention will be described herein in the context of illustrative fitness devices, along with illustrative apparatus, systems and methods for utilizing such fitness devices. However, it is to be understood that embodiments of the invention are not limited to the illustrative methods, apparatus, systems and devices but instead are more broadly applicable to other suitable methods, apparatus, systems and devices.
In some embodiments, a fitness device or unit is provided for performing assisted stretching exercises, including assisted back stretching. The fitness device is designed for use by fitness practitioners, also referred to as users, for back stretching and other exercises. The fitness devices described herein are configured for use in a gym environment, a physical training facility, etc. A fitness device, in some embodiments, is configured as a mobile unit to facilitate use in a training facility environment and other use cases.
It is anticipated that users will be trained to operate the fitness devices described herein, such as through one-on-one interaction with a certified trainer, through self-instruction via instruction cards affixed to the fitness devices, via training pamphlets, videos, etc.
The fitness devices described herein may be utilized to impart various exercise actions on a user, including the application of an angular displacement about the lumbar region, for the purpose of lumbar flexion and extension. To use the fitness device, the user situates their body facing toward the fitness device (e.g., prone), facing away from the fitness device (e.g., supine) or facing sideways (e.g., lateral) to the fitness device, and then locates their feet in a footrest or foot support of the fitness device. In some embodiments, the footrest includes foot restraints with resistive motion capability, to enhance stretching of one or more of the user's back, trunk, legs, thighs, upper and lower extremities, etc. It should be noted, however, that the fitness device may be used without the footrest as desired, even in cases where the footrest is installed or attached to the fitness device.
In the various orientations (e.g., prone, supine, lateral), the user's arms may be positioned to rest on an arm support of the fitness device. The user's arms and other portions thereof may also or alternatively be supported with the assistance of a chest harness or other strapping from the underarms to some attachment point on a rotating table of the fitness device. This may include, in some embodiments, the user of special hand-wrist supports with integral hooks for attachment to an overhead bar or other portion of the fitness device.
The arm supports in some embodiments include hand grips with controls for enabling powered rotation of the entire assembly, providing full body stretching with the user. Such full body stretching may include positions of body flexion and extension of the human torso, including allowing the lower body mass and restrained feet of the user to undergo muscular stretching, aiding range of motion of all of the body's joints, including the spine or back of the user. In addition to the arm supports or rests, an overhead bar may be provided on the fitness device allowing the user to support their weight. The arm supports or rests and overhead bar, either individual or in combination, may also or alternatively provide the ability for the user to perform active isotonic exercise and stretching. The use of an overhead bar, however, is optional and not required.
Throughout the description, the following terms are used to describe planes and axes.
The anteroposterior axis refers to the human body axis (z-axis) which runs horizontally fore and aft through the human body, approximately through the vertical mid-point, parallel to the ground and perpendicular to the coronal plane. The anteroposterior axis is also referred to as the dorsoventral axis.
The coronal plane refers to the vertical plane which divides the human body between its forward (ventral) and rear (dorsal) portions. This plane contains the lateral (x) axis and craniocaudal (y) axis, perpendicular to the anteroposterior (z) axis.
The craniocaudal axis refers to the human body axis (y-axis) which runs vertically through the human body, perpendicular to the transverse plane.
The lateral axis refers to the human body axis (x-axis) which runs laterally (e.g., left/right) through the human body, roughly through the vertical mid-point, parallel to the ground and perpendicular to the sagittal plane.
The median plane refers to the sagittal plane located midway in the human body. The median plane contains the craniocaudal (y) axis and the anteroposterior (z) axis, perpendicular to the lateral (x) axis. The median plane is also referred to as the mid-sagittal plane.
The sagittal plane refers to any vertical plane which divides the human body into lateral (e.g., left and right) segments.
The transverse plane refers to the horizontal plane which approximately divides the human body between its upper and lower portions. The transverse plane contains the lateral (x) axis and anteroposterior (z) axis, perpendicular to the craniocaudal (y) axis. The transverse plane is also parallel to the ground with the person in a vertical position (e.g., standing upright).
The x-axis refers to the left-right axis through the human body. See the discussion above regarding the lateral axis.
The y-axis refers to the longitudinal (e.g., up/down) axis through the human body. See the discussion above regarding the craniocaudal axis.

In some embodiments, fitness devices enable various core muscle stretching activities. The fitness devices described herein are designed to increase user wellness, flexibility and mobility, range of motion, and to improve posture and overall athletic performance. As will be described in further detail below, fitness devices in some embodiments provide power resistance stretching. The disclosed fitness devices are also multi-positional, and provide for self-activated stretch and other exercise of users thereof. Thus, the fitness devices described herein provide an alternative to less effective and time-consuming core stretch regimens. It should be appreciated, however, that the fitness devices described herein may be used as a supplement to other core stretch regimens rather than as a replacement to such other core stretch regimens. The fitness devices described herein are designed to be user-friendly, providing appeal to a wide variety of users (e.g., from beginner exercise enthusiasts to professional athletes).
Advantageously, users of the fitness devices described herein can safely perform a variety of stretch and other exercise programs utilizing three-dimensional (3D) positioning capability. Fitness devices may therefore have custom positioning tailored towards users' individual needs. In some embodiments, fitness devices are equipped with power and manual controls as well as adjustable table height, foot supports or restraints, arm supports, etc. Users can expect increased flexibility, enhanced performance, and improved posture, whether approaching or utilizing the fitness devices in the supine, prone or lateral positioning. In some embodiments, fitness devices are designed to be controlled entirely by the users thereof without requiring supervision. Instructions for use of the fitness devices may be displayed on the fitness device, on a mobile computing device of a user that is coupled or otherwise paired with or connected to the fitness device, etc.
Core muscle stretching may be instrumental for physical success, and is enabled using the fitness devices described herein in illustrative embodiments. Fitness devices are advantageously 3D multi-positional (e.g., supine, prone, lateral), providing self-activated power resistance stretching, enabling increased flexibility, enhanced performance and improved posture. Fitness devices described herein also provide assessment capability, and enable both active and passive user participation (e.g., in isotonic, isometric and isokinetic exercise). The fitness devices described herein may be used for a variety of purposes, including prevention, wellness, and rehabilitation. Further, controls of the fitness devices described herein are user-friendly, motivating and time efficient.
In some embodiments, fitness devices are used for targeted stretching and exercising of specific muscle groups to increase flexibility, mobility and strength of a user thereof. Performance of the user is also enhanced, and posture is improved through stretching. The user can decide to use the fitness device in any desired position (e.g., supine, prone, lateral). The decision is dependent on which specific muscles and joints that the user is targeting. In some embodiments, a quick reference exercise chart is affixed to the device at a side panel thereof, to guide the user to which position is best suited to meet a user's core stretching objective. The quick reference exercise chart may also be output on a display of the fitness device, or a device coupled or otherwise paired or connected thereto (e.g., a smartphone or other mobile computing device of the user). An exercise routine may involve the user utilizing the fitness device in multiple positions. Each position may affect the core muscles of the user differently. The supine position (e.g., facing away from the fitness device) provides an extension position. The prone position (e.g., facing towards the fitness device) provides a flexion position. The lateral position (e.g., facing sideways, both left and right relative to the fitness device) provides a lateral position.
Prior to commencing a stretch or exercise routine, the fitness device may be set up and positioned by the user. Fitness device set up and positioning, in some embodiments, includes adjusting for height of the user. The user, for example, may select a height setting on a control panel of the fitness device, which automatically raises or lowers the rotating frame of the fitness device in order to align the center of a contoured lumbar support thereof to a center of a lower back and pelvis junction of the user. The user may then select, via the control panel, the degree or intensity of the stretching force to be applied. In some embodiments, the stretching force options are graded, ranging from (1) mild to (2) moderate to (3) intense. It should be appreciated, however, that there may be fewer or more than three stretching force options. The control panel, for example, may have a dial or other continuous control range for adjusting the stretching force to more than three stretching force options.
The intensity of the stretch or resistance may be managed by sensors located in an ankle or foot restraint system or component of the fitness device, allowing for consistent measure of resistance during use of the fitness device. One or more sensors may also or alternatively be located on or otherwise be part of a base assembly, elevation assembly, or other component or components of a fitness device. Measurements from such sensors, in addition to managing the intensity of the stretch or resistance provided by the foot restraint system or component, may also or alternatively be used in controlling various other motion or movement of components of a fitness device. In other embodiments, however, adjustment or control of motion or movement of components of a fitness device (e.g., lift and rotation of a table, tilt of portions of a cushion assembly, etc.) may be independent of any feedback from sensors such that the sensors may be omitted.
When included, sensors may provide measurements or feedback of various aspects of the fitness device, including but not limited to height of a table of the fitness device, rotation of the table of the fitness device, tilt or elevation of portions of a cushion assembly, etc. In some embodiments, resistive force applied by a foot restraint provides the necessary sensor feedback to precisely determine the degree of rotation and lift of the table. It should also be noted that the fitness device may include an optional elevation assembly that enables a change in height of the table. The elevation assembly, however, may offer only an attachment point for the rotating table and not a change in height of the table (e.g., the elevation assembly remains at a fixed height). Height adjustment displacement feedback enables the table to variably rotate on its axis, such as within a rotational arch of 0 to 60 degrees, and also limits excessive elevation of the user's foot restraint system from its attachment to the base assembly.
Optimal user positioning may be achieved by the user placing their feet and/or ankles into a foot restraint system or component of the fitness device. Very tall and very short users, in some cases, may need to adjust a height of arm supports of the fitness device to achieve maximum benefit. The foot and ankle restraint system or component combined with the arm supports ensure proper stretching force or resistance.
Fitness devices, in some embodiments, include control buttons or other control interface features conveniently located at handles or hand grips that are operated by the user to initiate rotation and elevation of the upper body support platform of a fitness device to allow for full body stretching. Dynamic motion of the fitness device may be entirely power driven, enabling effective passive stretching of the muscles. A fitness device may also or alternatively be configured for manual driven motion for active stretching of the muscles. A contoured lumbar support section of the fitness device may be configured to at least one of rotate outwardly relative to a thoracic section of the fitness device and extend outwardly as an upper body support platform of the fitness device rotates away from a home position. Both the lumbar support section and the thoracic section may be embodied as cushions of a cushion assembly mounted to a table of the fitness device. The user may fine-tune the stretching experience and reduce the maximum force by limiting the extent of travel of the rotating platform (e.g., a table of the fitness device). This may be accomplished by releasing motion control buttons of the fitness device.
Fitness devices described herein may be programmed to perform various exercise and stretch routines. A given exercise or stretch routine may be associated with parameters for: an exercise cycle; a number of sets; a number of repetitions; and timing. The exercise cycle defines a complete rotation of the fitness device from a vertical home position to the limit of full rotation, and then back to the initial starting position. The user can decide if they want to exercise utilizing one or multiple positions (e.g., prone, supine, lateral) in one or more sets. In some embodiments, exercise cycle parameters are separately set for different positions of use of the fitness device (e.g., there may be a first exercise cycle for the prone position and second exercise cycle for the lateral position, with the first exercise cycle and the second exercise cycle having different ranges or limits of rotation). The number of repetitions in a typical regime may be to exercise between 5 and 10 repetitions in each position. It should be appreciated, however, that the user may select fewer than 5 or greater than 10 repetitions as desired. Timing parameters control the length or duration of each exercise cycle, which is expected to last between 10 and 20 seconds but may be shorter or longer as desired. The user may customize the time length of any given exercise cycle by delaying or prolonging that exercise cycle using hand-control buttons or other control interfaces of the fitness device.
In some embodiments, the fitness device includes an overhead bar facilitating isometric and isotonic stretching. The inclusion of the overhead bar provides the ability to implement upper body superficial and deep core muscle stretching, as well as upper extremity arm, scapular and forearm muscular and joint recruitment during the stretching process if desired.
Any discomfort of the user may be immediately mitigated by the user using the hand-control buttons or other control interfaces of the fitness device to stop or reverse the motion of the rotating platform of the fitness device. As an example, discomfort to resistive ankle or foot restraints, or the perception of stretching, may be mitigated using such controls. The fitness device may also be configured with various emergency stop switches, buttons or other control interfaces conveniently located on or near handle bars and hand grips accessible by the user in the prone, supine and lateral positions.
The height of the table 106 is configured to increase or decrease as stretch is applied via rotation of the table 106 about the table rotation axis 105. For example, in some embodiments the elevation assembly 104 is actuated to raise or lower the table 106 as it rotates to provide a desired amount of stretch of a user positioned in the fitness device 100 as will be described in further detail below. It should be noted that stretch may be provided by lifting a user positioned in the fitness device 100 (e.g., via elevation assembly 104) instead of rotating the user by rotating the table 106 about the table rotation axis 105. As described above, stretch may also be provided through combinations of lifting the table 106 (e.g., via elevation assembly 104) and rotating the table 106 (e.g., via rotation about the table rotation axis 105).
It should be appreciated that there are various alternatives to the single-column elevation assembly shown in
To use the fitness device 100, a user situates their body relative to the fitness device 100 by facing toward the fitness device 100 (e.g., prone), facing away from the fitness device 100 (e.g., supine) or laterally facing the fitness device 100. These different positions of the user relative to the fitness device 100 will be described in further detail below in conjunction with
To restrain the user on the table 106, the user's underarms are positioned to rest on the underarm support 112 coupled to the restraint and overhead bar 108. The user then holds onto hand grips on different portions of the restraint and overhead bar 108 that are available for the particular position of the user relative to the fitness device 100 (e.g., prone, supine, lateral). Different configurations of hand grips on the restraint and overhead bar 108 will be described in further detail below with respect to
Once the user is securely positioned on the fitness device 100, the user can utilize controls (e.g., located on the base assembly 102, elevation assembly 104, table 106, restraint and overhead bar 108 including hand grips thereof, etc.) to rotate the table 106 from the starting position shown in
Controls located on hand grips of the restraint and overhead bar 108 (as well as controls positioned on the table 106 or one or more other sections of the fitness device 100 providing user interface features) allow powered rotation of the table 106, including flexion and extension and lateral flexion positioning of the human torso of the user. The lower body mass and optional foot restraints may be used to provide additional resistance. Gravity acting on the user provides additional benefits for the stretch exercises.
For additional stretch, the user of the fitness device 100 in some embodiments utilizes optional foot restraints which are on or coupled to the base assembly 102. The foot restraint provides mechanisms for attaching and securing the user's feet. Use of the foot restraint also provides resistance to the forces and motions imparted on the user by the elevation and rotational motions applied by the table 106. The foot restraint, in some embodiments, is repositionable (e.g., via rotation, translation along a track, etc.) to allow prone, supine and lateral use. The height of the table 106 in some embodiments is settable or programmable (either powered or non-powered) to compensate for user height and body proportions. It is assumed that the foot restraints described herein are configured for removable attachment or mounting to a fitness device. In some embodiments, however, a foot restraint may be formed integrally with a fitness device such that the foot restraint is not removable.
As noted above, the fitness device 100 includes a base assembly 102, an elevation assembly 104, a table 106 and a restraint and overhead bar 108. The base assembly 102 in some embodiments includes a platform, a foot restraint, a computerized user interface, system controls, a leg force monitor, etc. The elevation assembly 104 includes one or more elevation posts (e.g., telescoping posts) to raise or lower the height of the table 106. The table 106 also provides hand grips and a cushion assembly 110 including different cushions for the head, thoracic and lumbar sections of the body of the user. In some embodiments, the cushion assembly 110 further includes a pelvic cushion, separate from the lumbar cushion, which is rotationally secured to the lumbar cushion supporting the pelvis and thighs of the user. The pelvic and lumbar cushions may be connected for coordinated longitudinal movement and rotational movement. The feet of the user of the fitness device 100 turn with the pelvis of the user (e.g., the feet of the user follow rotational movement of the pelvis of the user). The sizing of the pelvis cushion further facilitates access to the user by an assistant or trainer. The restraint and overhead bar 108 includes underarm supports 112 as well as various hand grips.
The restraint and overhead bar 108 is configured to open (e.g., via rotation about restraint and overheard bar rotation axis 107) in order to facilitate entry of the user into the fitness device 100, and for providing a secure restraint for the user while in the fitness device 100. One or more actuators affixed to the base assembly 102 and/or elevation assembly 104 are configured to raise and lower the table 106. One or more actuators affixed to the elevation assembly 104 and/or the table 106 are configured to allow the table 106 to pivot about the table rotation axis 105. One or more actuators within the table 106 are configured to allow the different sections of the cushion assembly 110 to move relative to one another and the table 106. In some embodiments, such various actuators comprise respective linear actuators, such as linear actuators powered by electric motors. It should be appreciated, however, that various other types of actuators may be used in place or in addition to such electric motor-powered linear actuators.
In some embodiments, the operation of the fitness device 100 is controlled by a user gripping each of the prone hand grips 402 (or each of the supine hand grips 404, or two of the overhead bar hand grips, or any combination of two of the hand grips 402, 404 and 406) with the user's left and right hands. When the user actuates controls on each of the prone hand grips 402, the table 106 will rotate. When the user actuates controls on just one of the prone hand grips 402, the table 106 stops rotation. When the user does not actuate the controls of either of the prone hand grips 402, the table 106 reverts from a rotated position (e.g., as shown in
Controls on the hand grips 402, 404 and 406 are not limited to use solely for controlling the rotation of the table 106. Controls on the hand grips 402, 404 and 406 (and controls elsewhere on the fitness device 100) are used to set any combination of the following parameters via a user interface: settable table movements such as translate up, translate down, rotate forward, rotate back, etc.; settable foot restraint resistive exercise force and limits; settable rate of stretch; settable lumbar enhancement level; settable number of repetitions; settable number of sets; automatic return; feedback settings; etc. Automatic return control allows the user to return to the starting position (e.g., as shown in
In some embodiments, the fitness device 100 is programmed with a set of default parameters. The default parameters allow the user: to select limits prior to starting exercise; to have complete control over table movement; and to control exercise using on-board controls. The fitness device 100 is configured to be programmed with one or more presets, such as beginner, intermediate and expert. User-defined profiles for different preset stretching and exercise routines in some embodiments are loaded into the fitness device 100 through a mobile device of the user that is connected to the fitness device 100. In some embodiments, additional incremental control is provided for increased effectiveness.
Feedback settings may take on various forms. In some embodiments, the fitness device 100 is configured to allow the user to set an audible tone to indicate when the user has reached a programmed level of stretch, time at a particular stretch level, etc. The fitness device 100 may also be configured to allow the user to set an audible tone with a beep rate of varying frequency to indicate when the user has reached a programmed level of stretch, time at a particular stretch level, etc. The fitness device 100 is not limited to providing auditory feedback. In other embodiments feedback is provided in the form of haptic feedback or vibration of controls on the hand grips 402, 404 and 406, or on cushions of the cushion assembly 110, etc. In some embodiments, the fitness device 110 also or alternatively includes a display screen or indicator lights for providing this and other feedback.
The fitness device 100 includes a user interface unit, also referred to as a UI, providing the user with the ability to control the parameters of operation of the fitness device 100. In some embodiments, it is expected that settings are set on the UI prior to exercise. In other embodiments, however, the user adjusts settings later during the exercise cycle using the UI. The UI may be located at various positions on the fitness device 100, including but not limited to: on the base assembly 102 in an orientation easily accessible to the user prior to getting onto the fitness device 100; at eye level on the back or side of the table 106 in an orientation easily accessible to the user prior to getting onto the fitness device 100; in an auxiliary unit co-located with the fitness device 100 or remotely located relative to the fitness device 100; in a re-locatable unit such that the user can see a display to track system status, such as exercise session progress, and to modify settings while on the fitness device 100 in the midst of exercise; and in an application provided on a mobile device such as a smartphone, tablet, smartwatch, etc. of the user.
Controls for the UI in some embodiments include one or more of: a graphical user interface (GUI) on a touchscreen; a plurality of buttons and/or switches; a plurality of buttons and/or switches with a display for indicating current selections; and on-board controls accessed at or near one or more of the hand grips 402, 404 and 406, etc. In some embodiments, the on-board controls at or near one or more of the hand grips 402, 404 and 406 include one or more of: control buttons configured for activation by thumbs of the user; trigger-like controls activated by one or more of the fingers of the user; a control activated by squeezing the hand of the user; controls activated by twisting the hand grip (e.g., similar to a motorcycle throttle); a joystick; a sensor that detects whether a hand is holding the hand grip; and one or more secondary buttons for providing independent control of various portions of the fitness device 100, such as a position of one or more portions of the cushion assembly 110 (e.g., a position of the combined thoracic and head cushion 302, a position of the lumbar cushion 304, etc.).
In some embodiments, the UI is configured to store local profiles of different users, so that a user is enabled to save and load customized stretch and other exercise routines while using the fitness device 100. The local profiles may also include information allowing the fitness device 100 to automatically adjust for the height and size of different users.
For control of movements, some embodiments utilize the following control scheme.
The control scheme is described for the supine position of the user, but it should be appreciated that the same movement and controls may be used for the prone and lateral positions. The fitness device 100 is configured in some embodiments: to rotate the table 106 backwards (and apply optional foot restraint tension) when controls are activated by both the left and right hand of the user; to hold position of the table 106 (and optional foot restraint tension) constant when either the left hand or the right hand releases the control while the other hand continues to active the control; and to rotate the table 106 forwards (and release optional foot restraint tension) when the user releases the controls from both hands. In another embodiment, one hand is used to control up and down movement of the table 106 while the other hand controls the forward and backward rotation of the table 106. In another embodiment, one rocker switch controls up and down movement of the table 106 while another rocker switch controls forward and backward rotation of the table 106 (where the rocker switches are located for access by a single hand or one by each hand of the user). In other embodiments, any of the above control schemes are utilized with separate lumbar enhancement control located on either or both of the hand grips 402, 404 and 406 being held by the user. In still other embodiments, any of the above control schemes are adjusted such that all controls are accessible and activatable using only one hand.
The pivot point at the base of the feet of the user in some embodiments is counterbalanced with a pivot point at a pelvic support of cushion assembly 110 as described above, where the pivot point of the pelvic support is underneath the pelvic cushion, or below and separate from the pelvic cushion altogether (e.g., on the table 106 or another portion of the fitness device 100). The user interface or UI 506 provides controls for setting exercise parameters and other parameters of the fitness device 100 (e.g., by the user 501 prior to the user 501 being secured onto the fitness device 100).
In the embodiment of
The feet of the user 501 rest between the bolsters of the foot restraint 504 that comfortably grip the feet. The bolsters of the foot restraint 504 may be cylindrical as shown, or may be another shape that is both comfortable and secure (e.g., square or rectangular, elliptical, etc.). In other embodiments described in further detail below, a foot restraint may use straps, clips, boots, etc. instead of bolsters for securing the feet of the user. The foot restraint 504 keeps the soles of the feet in contact with or close to the platform 502 of the base assembly 102, with limited travel in the y-axis direction. In some embodiments, however, it is desired to have at least some travel in the y-axis direction for comfort of the user 501. The foot restraint 504 allows free movement along the z-axis, as well as rotation about the x-axis (e.g., “into” the page). As shown in
In some embodiments, the foot restraint 504 is removably coupled to the base assembly 102 of the fitness device 100. Thus, the foot restraint 504 can be replaced with a wobble board for enabling the user to perform various balance exercises. Thus, the fitness device 100 provides a modular fitness system enabling various types of stretching and other exercise.
In some embodiments, controls of the fitness device 100 are configured to position the elevation and rotation of the table 106 in a manner that maintains a predetermined force (or force range) on the feet of the user 501 without elevating the feet of the user 501. The predetermined force may be constant, or determined according to some defined function (e.g., where the predetermined force or force range is proportional to an amount of rotation, lift, tilt or other stretch experienced by the user) as described in further detail below. As the table 106 of the fitness device 100 rotates backward, the tendency will be to lift the feet of the user 501. The controls of the fitness device 100 will compensate for this tendency, in some embodiments, by lowering the height of the table 106 and/or varying the resistance or force provided by the foot restraint 504, thereby applying a stretch to the body without lifting the feet into the air. The foot restraint 504 includes a force sensing system that feeds into the controls of the fitness device 100 to appropriately position the elevation and tilt of the table 106 to achieve a desired stretch. It should be appreciated that the force sensing system need not be physically housed in the foot restraint 504. In some embodiments, the force sensing system is coupled to or compromised within one or more of the base assembly 102, the elevation assembly 104, the table 106, the restraint and overhead bar 108, etc.
As shown in
In the fitness device 900, the elevation assembly 904 and table 906 have a slotted link assembly to eliminate the rotation rod of fitness devices 100 and 800. The rod in fitness device 900 is constrained to stay vertical. In order to remain vertical, the anchor point will translate relative to the anchor point as the table 906 rotates. Advantageously, such a configuration enables the elevation assembly 904 to be slimmer than the elevation assembly 804, because the actuator angles out as the table 806 rotates backwards in fitness device 800.
The elevation assembly 1004 of the fitness device 1000 also separates higher, and the elevation assembly 1004 and table 1006 provide a different rotational linkage solution. The linkage solution of the elevation assembly 1004 may use any of the configurations shown in
The elevation assembly 1104 and table 1106 provide a multi-link variable geometry in a main trunk that mimics the human spine. The elevation assembly 1104 also separates higher than that of the fitness devices 100, 800, 900 and 1000. The elevation assembly 1104 may achieve vertical lift in a manner similar to that described above with respect to elevation assembly 1004. For rotation, the elevation assembly 1104 includes multipole rotary actuators to provide a curved, contoured bending back as illustrated. In some embodiments, multiple linear actuators with respective hinge points may be utilized in place of one or more of (or all of) the rotary actuators.
It should be appreciated that features such as the locations of hand grips, the force application system 702, the type of restraint and/or overhead grip bars, underarm supports, cushion assemblies, table and elevation assembly linkages, foot restraints, etc. that are described with respect to one of the fitness devices 100, 800, 900, 1000 and 1100 may be combined in various ways. For example, the restraint and overhead bar 108 of the fitness device 100 may be replaced with any of the bars 808, 908, 1008 and 1108. Similarly, the type of foot restraint used in fitness device 100 may vary (e.g., the foot restraint 504 may be replaced with any of the foot restraints 604, 614, 624, 634 and 1144). This is also true for fitness devices 800, 900, 1000 and 1100. More generally, it should be appreciated that a particular feature described in conjunction with one of the fitness devices 100, 800, 900, 1000 and 1100 (as well as other fitness devices described below) may be used in combination with features of any other ones of the fitness devices 100, 800, 900, 1000 and 1100 (as well as other fitness devices described below) unless specifically noted otherwise.
The overhead bar 1308-1 and underarm support bars 1308-2 are adjustable for accommodating different-sized users. The overhead bar 1308-1 and/or the underarm support bars 1308-2 are also configured to swing outwards or rotate to facilitate entry of a user 1301 onto the fitness device 1300, or for securing the user 1301 onto the fitness device 1300.
The cushion assembly 1310 includes a bottom lumbar cushion and a set of head and thoracic cushions, where the different cushions adjust or slide relative to one another to accommodate user height and proportions in addition to or instead of using the elevation assembly 1304. The lumbar cushion of the cushion assembly 1310 also rotates or translates to enhance stretch.
The fitness device 1300 provides multifunctional exercise and conditioning, as controlled by the user 1301. The fitness device 1300 includes the elevation assembly 1304 and table 1306 that are rotationally connected to one another via a pivot point attachment. The lower portion of the fitness device 1300 includes the base assembly 1302 and the elevation assembly 1304. In this embodiment, the base assembly 1302 provides a single column rectangular support base sub-frame with four floor feet extensions to prevent tilting. It should be appreciated, however, that the base assembly of a fitness device may include a circular column support rather than a rectangular column support, a multiple column support, etc. The base assembly 1302 does not rotate with the user 1301. The elevation assembly 1304 is coupled to the column support of the base assembly 1302, and is configured to support and provide height selective adjustment as well as pivot and activation mechanisms for rotating the top portion of the fitness device 1300 (e.g., the table 1306, overhead bar 1308-1, underarm support bars 1308-2 and cushion assembly 1310) in a range (e.g., from 0 to 90 degrees, from 0 to 60 degrees, etc.). The table 1306 of the fitness device 1300 provides a metal support sub-frame, and the cushion assembly 1310 includes two individual user support cushions (e.g., a thoracic and head cushion, as well as a lumbar cushion). The top portion of the fitness device 1300 further includes underarm support bars 1308-2 with hand grips in both the front and rear (e.g., for use by the user 1301 in the supine and prone positions, respectively). The overhead bar 1308-1 also provides various hand grips (e.g., for use by the user 1301 in the lateral position, and optionally for use in the supine and/or prone positions). The table 1306, as noted above, is rotationally attached to the elevation assembly 1304 allowing rotation of the user 1301 from the vertical to the horizontal.
The table 1306 of the fitness device 1300 has, at its approximate upper third portion, a bend (e.g., of approximately 30 deg) in relation to the lower two thirds portions to provide backwards and forwards spine bending of the user 1301. The underarm support bars 1308-2 provide underarm tubular cushioned supports, which may be any desired shape for the comfort of the user. As noted above, the underarm support bars 1308-2 further include hand grips formed integrally therewith located in both the front and rear of the fitness device 1300. It should be appreciated that in some embodiments one or more hand grips are attached to or formed integrally with the table 1306 (e.g., such as on a back portion thereof for use by the user 1301 in the prone position). The overhead bar 1308-1 also includes various hand grips as illustrated. The hand grips of the fitness device 1300 are configured with controls (e.g., buttons, switches, etc.) to effect rotation of the table 1306 and optionally to provide lumbar extension and tilting. Such controls are configured for use by the user 1301 to adjust the tilt of the table 1306, to adjust force applied via optional foot restraints, to provide emergency stop switches for disabling motion of the fitness device 1300, etc. The underarm support bars 1308-2 are configured to rotate in and out on separate pivots for facilitating entry and exit of the user 1301 from the fitness device 1300. The hand grips on the underarm support bars 1308-2 in some embodiments are adjustable in and out to accommodate arm length size. The support pads of the underarm support bars 1308-2 in some embodiments are adjustable to provide additional securing of the user 1301 to the fitness device 1300.
As noted above, the bottom portion of the fitness device 1300 includes the base assembly 1302 providing a single column rectangular support sub-frame. The support sub-frame of the base assembly 1302 in some embodiments includes two self-contained air cylinders for providing the ability to adjust the top portion of the fitness device 1300 (e.g., via elevation assembly 1304) up or down without power or compressor functions. In other embodiments, however, the base assembly 1302 and elevation assembly 1304 are powered. The base assembly 1302 and elevation assembly 1304 in some embodiments comprise two pneumatic cylinders operated by hand-lever to provide an electric screw drive mechanism for permitting powered raising and lowering of the top portion of the fitness device 1300. This facilitates both height accommodation for the user 1301 and also allows for powered stretch functionality to move in the y-axis vertical direction as distinct and separate from power stretch (e.g., use of elastic bungees) from rotation of the table 1306. It should be appreciated that this functionality may also be used for isometric exercise by the user 1301, such as by requiring the user to hold or maintain a position or tilt of the table 1306 while a predetermined resistance (e.g., constant or variable) is provided through the powered mechanism of the base assembly 1302 and elevation assembly 1304.
The cushion assembly 1310 includes a fixed upper torso head and thoracic support cushion, which may in some cases be configured for rotation forward. The cushion assembly 1310 also includes the lumbar back support (e.g., which may be convex shaped) providing firm ergonomic support. The lumbar back support is also configured to extend outwardly (e.g., tilting) through powered mechanisms causing a change in the radius support favoring spinal extension and flexion of the lower back and pelvis of the user 1301, depending on the positioning of the user 1301 (e.g., prone or supine). In some embodiments, the lumbar back support is manually adjustable up and down to accommodate different user height by release of a locking slide mechanism.
The overhead bar 1308-1 extends outward to accommodate various positions of the user 1301, including prone, supine and lateral positioning. The overhead bar 1308-1 is manually adjustable up and down to accommodate different user height. The overhead bar 1308-1 is configured with controls for effecting rotation of the table 1306 and/or the lumbar back support of the cushion assembly 1310. The overhead bar 1308-1 also includes one or more emergency stop buttons and other types of user interface controls described herein.
As noted above, the fitness device 1300 is optionally coupled to one or more foot restraints, such as by coupling a foot restraint to the base assembly 1302 of the fitness device 1300. The foot restraints in some embodiments provide auxiliary mechanisms for strapping the ankles and/or feet of the user 1301 to provide increased traction effects that supplement gravity. The user 1301 utilizes their arms to self-pull against additional resistance provided by the foot restraint. The user 1301 also utilizes the pull created by active rotation and lift of the table 1306 to provide such increased traction effects. The fitness device 1300 during rotation in a backwards direction is configured to provide full and direct traction effects on muscles of the entire lower extremity of the user 1301, including the hamstrings, gluteal muscles, psoas muscles, etc., as well as the entire lower back musculature and the upper torso and arms of the user 1301.
Foot restraints in some embodiments utilize bungee strapping that originates at its proximal location from the sides or underneath an attachment point to one or multiple base sub-plates configured for attachment to the base assembly 1302 of the fitness device 1300. In some embodiments, the user 1301 places their feet in boots or cuffs with straps attached to one or more base sub-plates. In some embodiments, the user 1301 is secured to a foot restraint via straps or cuffs around the ankles of the user 1301 where the proximal end of a bungee cord attaches the ankle straps or cuffs to a sub-pedestal base, eliminating the need for base sub-plates.
Foot restraints in some embodiments utilize a bungee mechanism for attachment to the base assembly 1302 (e.g., via one or more base sub-plates, to a sub-pedestal base, or other type of base assembly mounting portion, etc.), with the bungee mechanism providing elastic recoil stretch with length and flexibility capabilities allowing full rotation of the table 1306 (e.g., to 60 degrees, to 90 degrees, etc.) as well as lift of the table 1306 relative to the base assembly 1302 (e.g., lift to 6 in, lift to 9 in, etc.). The bungee cords or straps of a foot restraint are interchangeable and configured for easy removal to enable the user 1301 to select amongst a variety of cords or straps with different (e.g., lighter and heavier) elastic strength to provide a wide range of customized resistance to accommodate users with different physical conditioning.
In some embodiments, the foot restraint includes separate right and left foot resistance cords or straps for attachment to one or more base sub-plates or sub-pedestal bases, allowing the user 1301 to select different resistance for the left foot and the right foot. The foot restraint, as noted above, may utilize ankle strapping for fastening to ankles of the user 1301 (e.g., a proximal strapping position) in various different configurations including but not limited to: one base sub-plate with fixed boots; two individual base sub-plates with separate straps; just boots or ankle straps attached directly to proximal bungees; one plate with one bungee; etc. Each end of a proximal bungee of the foot restraint is attached to the base assembly 1302 of the fitness device 1300 in various configurations, including configurations enabling sliding and/or rotation of the foot restraint. Sliding and rotation mechanisms of distal attachment of bungees (e.g., closest to the user 1301 via sub-plate and restraint straps) allow natural movement of the user 1301 during 0 to 60 degrees of full rotation of the table 1306 to accommodate changes in the position of the user 1301 (e.g., during lateral positioning of the user 1301 relative to the fitness device 1300).
The pedestal base of the foot restraint accepts a distal attachment point (e.g., in a center thereof, on left and right sides thereof, etc.), and provides forward and back translation movement so that as the table 1306 rotates in a backward direction towards 90 degrees, the bungees, cords or straps move forward and backward as necessary for comfort of the user 1301. The pedestal base attachment points in some embodiments are on a secured roller system or track that permits gliding movement. The pedestal base of the foot restraint may have various different design configurations providing attachment to sub-plates, directly to ankle straps, cords or bungees, etc. In some embodiments, the sub-base distal strap, cord or bungee attachment point of the foot restraint allows free rotation to accommodate a user 1301 (e.g., wearing boots, cuffs, straps, etc. attached to a sub-plate or directly to the pedestal base) enabling some side-to-side or lateral positioning of the feet of the user 1301 in addition to allowing face forward or prone positioning and face outward or supine positioning. The foot restraint includes safety mechanisms for safely applying additional traction to the user 1301, such as through a belt tensioning system, through dial control against a resistance sliding mechanism, etc.
As illustrated in

The fitness device 2400 includes underarm supports 2408-2 with hand grips 2411, where the underarm supports 2408-2 are configured to adjust for user height along a track 2413 within the table 2406 as illustrated. The overhead bar 2408-1 of the fitness device 2400 is also positioned along the track 2413, such that the overhead bar can be adjusted to suit a size of the user 2401 and desired stretch or other exercise type. The overhead bar 2408-1 of the fitness device 2400 may also rotate to accommodate size of the user 2401 and desired stretch or other exercise type.
The feet of the user 2501 are secured with foot restraint 2514, which enhances the stretch of the user 2501 as the table 2506 of the fitness device 2500 is rotated backwards. In the
Similar to the fitness device 2400, the overhead bar support 2508-1 and the belt support 2508-2 of the fitness device 2500 are mounted in a track 2513 of the table 2506, permitting adjustment for user size and type of stretch or other exercise. In the fitness device 2500, the underarm supports are embodied as the belt support 2508-2 that holds the user 2502 in place. The overhead bar 2508-1 may include two distinct (left and right) portions that are mirror images of one another. The two portions of the overhead bar 2508-1 may, but are not required to be, connected to one another in the center.
The feet of the user 2701 are secured with foot restraint 2714, which enhances the stretch of the user 2701 as the table 2706 of the fitness device 2700 is rotated backwards. In the

In some embodiments, the height control module 3902, rotation control module 3904 and tilt control module 3906 are implemented as proportional-integral-derivative (PID) control modules that operate according to the equation:
where u(t) is the control output, e(t) is the difference between reference and measured control input state (“error”), and Kp, Kt, and Kd are control coefficients (proportional, integral, and derivative, respectively).
The height compensation module 3908 is configured to reduce the reference height, Href to limit the applied force on the user by the foot restraint. The height compensation module 3908 takes as input the maximum allowable applied force Fmax and the measured force Fmeas, and provides an output height Hcomp according to the equation Hcomp=fhc(Fmeas,Fmax), where fhc denotes a height compensation function. The output height Hcomp and the reference height Href are provided to a summer, the output of which is supplied to the height control module 3902 along with the displacement height measured by the height sensor xh. The height control module 3902 in turn activates the height actuator Mh to adjust the height of the table 106 of the fitness device 100 (e.g., using the base assembly 102 and/or elevation assembly 104).
The rotation motion resolution module 3910 and tilt motion resolution module 3914 are each configured to convert a measured rotational or linear displacement to a measured angle. The rotation motion resolution module 3910 takes as input the measured rotation displacement from the rotation sensor xr, and outputs the measured rotation angle θr according to the equation θr(t)=frm(xr(t)) where frm denotes a function for conversion of the measured rotation displacement and t denotes time. It should be noted that the measured rotation angle θr may be independent of any feedback from displacement height sensors or feedback from sensors measuring resistance from the foot restraint or base assembly sensors. The tilt motion resolution module 3914 takes as input the measured tilt displacement from the tilt sensor xt, and outputs the measured tilt angle θt according to the equation θt(t)=ftm(xt(t)) where ftm denotes a function for conversion of the measured tilt displacement.
The rotation motion generation module 3912 and tilt motion generation module 3916 create the exercise motion profile of the table 106 of fitness device 100. The rotation motion generation module 3912 takes as input the parameters Nreps denoting the number of exercise repetitions and θrmax denoting the maximum rotation angle, and outputs the generated reference rotation angle θrg according to the equation θrg (t)=frg (θrmax, Nrep, S1, Sr) where frg denotes a function for generating the reference rotation angle, and St and Sr denote logic states (e.g., on/off) for left and right user switch controls, respectively. The tilt motion generation module 3916 takes as input the generated reference rotation angle θrg and generates the reference tilt angle θtg according to the equation θtg(t)=ftg(θrg(t)) where ftg denotes a function for generating the reference tilt angle. The reference rotation angle may be based at least in part on feedback from sensors of a selected maximum ankle resistive force, or may allow rotation to the maximum limits of table rotation and limits of foot restraint motion.
The outputs of the rotation motion resolution module 3910 and rotation motion generation module 3912 are provided to the rotation control module 3904 to activate the rotation angle actuator Mr. The outputs of the tilt motion resolution module 3914 and tilt motion generation module 3916 are provided to the tilt control module 3906 to activate the tilt angle actuator Mt.
