Description

Nuer-201-2woTITLE MOBILE MODULAR BODY WEIGHT SUPPORT GAIT AND BALANCE TRAINING FRAME WITH LATERAL STABILIZERS CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of United States Provisional Serial No. 63 / 746590 entitled Lightweight Mobile Modular Customizable Body Weight Support Gait and Balance Training Frame With Lateral Stabilizers filed on January 17, 2025, the entire contents of which are incorporated by reference herein for all purposes.TECHNICAL FIELD

[0002] The present disclosure relates generally to medical and rehabilitation equipment.More specifically, the present disclosure describes a patient body-weight support gait and balance training device.BACKGROUND

[0003] Patient rehabilitation following orthopedic injury, neurological impairment, or amputation frequently requires structured balance and gait training and supported ambulation. Conventional body-weight support systems and patient mobility devices are often large, heavy, expensive, non-mobile and intended primarily for institutional or clinical environments. These systems are typically complex, difficult to transport, and not readily adaptable for use in smaller spaces such as homes, hallways, patient rooms or private therapy settings. In addition, many existing devices lack modularity and do not permit disassembly or reconfiguration to accommodate users of differing body sizes, therapeutic needs, or available space constraints.

[0004] A further limitation of conventional patient support systems is the absence of adequate lateral stabilization of the torso and controlled freedom of movement and balance. Existing devices sometimes restrict a patient's range of motion, limiting the ability to practice turns, side-stepping, perturbations or backward movement— activities essential to functional gait or balance retraining. The lack of adjustable lateral support components also increases the risk of imbalance or falls and correct positioning andNuer-201-2wokinematics during rehabilitation exercises, thereby elevating safety concerns for both the patient and the attending caregiver.

[0005] Cost and accessibility also pose significant barriers. Current rehabilitation support frames and technologies are frequently priced beyond the reach of individual consumers and are not designed for easy setup, portability, or storage. As a result, many patients are unable to continue gait and balance training at home after discharge from professional care, slowing recovery and reducing long-term therapeutic outcomes.

[0006] Accordingly, there remains a need for an improved patient support device that is lightweight, modular, and capable of providing customizable body-weight support with gait and balance assistance and lateral stabilization in a compact form factor.Nuer-201-2woSUMMARY

[0007] The disclosure relates generally to a patient support device that is lightweight, modular, and capable of providing customizable body-weight support with gait and balance assistance and lateral stabilization in a compact form factor.

[0008] In one embodiment, The present disclosure relates to a patient support device and related systems and methods for assisting a patient during rehabilitation activities such as gait training, balance training, and hands-free ambulation.

[0009] In one embodiment, the patient support device includes a support frame formed by at least two vertically extending support bars, each having an upper end and a lower end, a horizontal support bar extending between the vertically extending support bars at the upper end, and base units coupled to the vertically extending support bars proximate the lower end. Together, the vertically extending support bars, the horizontal support bar, and the base units define a stable support frame configured to support patient movement during rehabilitation.

[0010] The patient support device further includes at least two arm supports operatively coupled to corresponding vertically extending support bars. Each arm support is vertically adjustable relative to the support frame by repositioning the arm support along the corresponding vertically extending support bar, thereby allowing individualized height adjustment and accommodation of different patient sizes, postures, or therapeutic requirements. In certain embodiments, the arm supports are independently adjustable relative to one another to accommodate asymmetric patient positioning.

[0011] In some embodiments, the patient support device includes mid-frame inserts removably coupled to the vertically extending support bars at positions intermediate the upper and lower ends. Each mid-frame insert may comprise a rigid insert body configured to be received within a hollow interior of a vertically extending support bar to form a load-bearing joint. The mid-frame inserts may further include alignment features, such as detents, keyed flats, grooves, shoulders, or combinations thereof, to prevent rotational misalignment and to facilitate stable transfer of vertical and lateral loads from the arm supports into the support frame.Nuer-201-2wo

[0012] In certain embodiments, the vertically extending support bars include a plurality of vertically spaced adjustment openings, and the arm supports are selectively lockable at discrete vertical positions corresponding to the adjustment openings. The arm supports may include a spring-biased pull-lock mechanism having an attachment housing, a movable shaft disposed within the attachment housing, and a manually actuated pull pin operatively connected to the shaft. The shaft may be biased toward an engaged position in which the shaft extends into one of the adjustment openings to secure the arm support at a selected height.

[0013] In some embodiments, the arm supports are removably detachable from the midframe inserts without tools and are configured to provide hands-free ambulation support for a patient during rehabilitation activities.

[0014] In further embodiments, the patient support device includes upper inserts coupling the horizontal support bar to the vertically extending support bars and lower inserts coupling the vertically extending support bars to the base units, with the inserts forming removable, load-bearing joints. The vertically extending support bars may be formed from a plurality of modular bar sections that are selectively connectable to adjust an overall height of the support frame.

[0015] In certain embodiments, the base units include a bottom plate, one or more wheel plates coupled to the bottom plate, and one or more wheels coupled to the wheel plates, enabling rolling movement of the support frame. The support frame may further be collapsible from an operational configuration to a folded transport configuration to facilitate storage and transport.

[0016] In some embodiments, the patient support device further includes overhead attachment rings coupled to the horizontal support bar for suspending a body-weight support harness, and one or more force sensors disposed between the body-weight support harness and the support frame. Side attachment connectors and one or more lateral stability rings may be removably coupled to the vertically extending support bars to provide adjustable lateral stabilization for a patient during rehabilitation.

[0017] In another embodiment, a patient rehabilitation system includes the patient support device in combination with a patient-worn support assembly configured to be worn by a patient and a suspension interface coupling the patient-worn support assembly to an upper portion of the support frame. The patient-worn support assembly may provideNuer-201-2wobody-weight support to the patient during rehabilitation, while the arm supports provide upper-extremity support independently of the patient-worn support assembly during patient movement or training.

[0018] In yet another embodiment, a method of supporting a patient during rehabilitation includes providing a patient support device having vertically extending support bars, a horizontal support bar, base units forming a support frame, and at least two arm supports coupled to the vertically extending support bars. The method further includes adjusting a vertical position of each arm support by repositioning the arm support along the corresponding vertically extending support bar and supporting at least a portion of the patient's upper body on the arm supports while the patient performs a rehabilitation activity.

[0019] In one embodiment, the device provides improved high intensity rehab training and step dosage in a fall safe environment for non-complex and complex patients

[0020] In one embodiment, the device provides the ability to train balance, correct gait kinematics and perturbations in clinic, home and community settings.

[0021] In one embodiment, the device provides the ability to provide an affordable, modular (assembly or disassembly and store in ten minutes) fall safe technology with lateral torso stability and hands-free ambulation capability for activities of daily living

[0022] Advantageously, the system and device provides safe, independent, and progressive mobility and balance training for a wide range of users, while maintaining affordability, portability, and ease of assembly for both clinical and home use. The device is lightweight and portable while maintaining high structural integrity, allowing a single clinician or caregiverto transport, quickly assemble, disassemble and assemble again repeatedly and position the system without the need for complex instructions or lifting equipment. Its portability enables use in a variety of indoor and outdoor environments, including clinical facilities, rehabilitation centers, community and private homes. The frame is modular and customizable, comprising detachable and interchangeable components that permit rapid assembly and disassembly fortransport or storage. This modular design allows changes to the frame's width, height, and configuration with an accessory package to accommodate both adult and pediatric and treadmill users.

[0023] Advantageously, an embodiment of the present disclosure provides a patient support system and device that provides modular, portable, customizable, easy-to-use,Nuer-201-2wosafe, and affordable fall-safe walking and balance rehabilitation in a clinic or home setting. The patient support device is modular and easy to transport, fits through most doorways, has lateral support attachments to encourage patient movement in all turns including 360 degree turns, lateral and backward directions, and is affordable for patients to purchase fortheir homes. The patient support device is lightweight but is still capable of supporting 180 Kg statically and 160 Kg dynamically.

[0024] The patient support system device allows a patient to safely walk around the clinic, in the community or their home without fear of falling and allows them to condition their body by being more active and walking further distances to recover from an orthopedic or neurological injury, disease, amputation, and prosthetic training. The frame can be customized for a large adult, treadmill or pediatric frame dimensions.

[0025] Advantageously, the system and device further provides lateral stabilization, balance and mobility training through the inclusion of integrated lateral support bands or stabilizers that apply controlled multidirectional tension and support. These stabilizers encourage natural movement and muscle engagement during gait and balance training, allowing the patient to safely practice turning, side-stepping, swaying, perturbations and backward walking. The system enhances safety by incorporating a waist belt or bodyweight support harness that evenly distributes the patient's weight and prevents falls. The combination of adjustable stabilizers and force-sensor connections (for objective measures) improves balance and user confidence, minimizing the risk of injury for both the patient and caregiver.

[0026] Advantageously, the system and device is adaptive for home or community use. The design utilizes cost-effective materials and simplified assembly, making the system accessible to individual patients who wish to continue therapy after discharge from professional care. Quick-connect design with the modular construction simplifies maintenance, cleaning, and component replacement.

[0027] Advantageously, the system and device may be used across a wide range of conditions, including orthopedic rehabilitation, neurological recovery, amputation and prosthetic training, and general conditioning for elderly or mobility-impaired users. In some embodiments, the frame can also integrate exercise pulley systems, sit to stand frames, balance waist belts, full body harness, treadmill frame accessories or weightNuer-201-2wosensor-based monitoring systems to support quantitative rehabilitation tracking and progress assessment.

In addition, the logic flows depicted in the accompanying figures and / or described herein do not necessarily require the particular order shown, or sequential order, to achieve desirable results. Other implementations may be within the scope of the following claims.Nuer-201-2wo

[0046] The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope is, therefore, indicated by the appended claims rather than by the foregoing description. All changes that come within the meaning and range of equivalency of the claims are to be embraced within their scope.

[0047] Referring now to FIG. 1, a top right perspective view of the support system with a patient supported in the support device therein is shown at (100). As described herein, the system (100) comprises both the support device (or frame) (101) and the harness (103) to attach to a patient. In embodiments, the harness may include various designs and waist belts and tension strap accessories for both the vertical and horizontal support of the harness and patient.

[0048] The patient support device (101) includes a frame for holding a patient (118). The frame includes vertical support bars (105a, 105b) and a horizontal support bar (106) expanding horizontally therebetween. Vertical support bars (105a, 105b) are coupled to the horizontal support bar (106) via upper inserts (108a, 108b). The frame (101) includes base units (160a, 160b) that are coupled to the vertical support bars (105a, 105b) at lower inserts (114a, 114b). Base unit (160a, 160b) includes wheels (116a, 116b, 116c, 116d) that allows the patient support device (101) to be moved. For example, the patient support device (101) can include four 360-degree castor wheels with brakes. The wheels may be designed for indoor and outdoor smooth surfaces, and the castor wheels may also have braking capability.

[0049] In embodiments, the frame components are coupled using inserts (108a, 108b, 114a, 114b) configured to mate telescopically with corresponding tubular members of the frame (101). Each insert comprises an elongated, rigid coupling element (bolth, washer and nut) dimensioned to be received within the interior cavity of a corresponding tube, or vice versa. The inserts, together with the rest of the device, may be fabricated from metal, composite, or reinforced polymeric materials and are sized to provide a snug, load-bearing friction fit with the inner diameter of the tube. The inserts include an outer surface that is generally cylindrical and sized to slide axially into a hollow tubular section of the frame. The insert may include one or more alignment features, such as detents, keyed flats, grooves, or protruding shoulders, that interact with complementary features on the interior surface of the tube. These features ensure proper orientation of the connected frame components and prevent rotationalNuer-201-2womisalignment during assembly and use. The insert may further include through-holes, cross-bores, or recessed fastening apertures that align with corresponding holes in the tube wall when the insert is fully seated. Fasteners, such as bolts, locking pins, spring- biased buttons, or quick-release mechanisms, may be passed through these aligned apertures to secure the insert in place and prevent axial movement between the mating components.

[0050] When assembled, the tubular members slide over the inserts until the stop shoulder, keyed surface, or alignment mark indicates full engagement. The resulting connection forms a rigid, stable, load-bearing joint capable of supporting the patient's weight and resisting multi-directional forces encountered during standing, balance training, gait training, or other rehabilitative activities carried out using the patient support device.

[0051] Still with reference to FIG. 1, the patient support device (100) can include left and right arm supports (112a, 112b). The arm supports (112a, 112b) are coupled to the vertical support bars (105a, 105b) at mid frame inserts (110a, 110b). In embodiments, the arm supports (112a, 112b) are vertically adjustable along the length of the corresponding support members of the frame in that they are directly fixed to the midframe inserts, and mid frame inserts can be adjusted up and down vertically. In other embodiments, the arm supports are slidable (or removable) and can be placed in any of the holes (122a, 122b) based on the comfort or height of the patient or user, and are not coupled to the mid-frame inserts.

[0052] In one embodiment, the attachment mechanism (discussed in greater detail in FIG.2 and FIG.5) comprises a pull-lock device, which may include a spring-biased detent or push-button element mounted within a bore of the arm support bracket. The pull-lock detent is biased outwardly toward an engaged position such that, when the arm support is moved along the vertical support bar, the detent automatically aligns with and protrudes into one of the arm adjustment holes (122a, 122b). This engagement prevents axial displacement of the arm support relative to the vertical support bar and secures the arm support at the selected vertical position.

[0053] To change the height of the arm supports (112a, 112b), the user may manually pull the spring-biased pull-lock element to retract it from the arm adjustment hole (122a, 122b), thereby releasing the engagement and permitting vertical movement. When the arm support is moved to a new position, the pull-lock element re-extends under springNuer-201-2woforce into the next arm adjustment hole (122a, 122b), thereby locking the arm support into the new height-adjusted position.

[0054] The repeated series of arm adjustment holes (122a, 122b) thus provides discrete, repeatable, and secure locking positions that allow fine-grained height adjustment of the arm supports to accommodate users of different sizes and therapeutic needs while maintaining stable mechanical engagement during use.

[0055] In further embodiments, the arm supports (112a, 112b) are configured to move inwardly toward, and outwardly away from, a central axis of the support frame to accommodate users of varying body widths, arm positions, and therapeutic requirements. Such inward and outward movement may be achieved through one or more swiveling, pivoting, or articulating mechanisms. By way of non-limiting example, each arm support (112a, 112b) may be coupled to a corresponding vertically extending support bar via a pivot joint defining a vertical or angled pivot axis, thereby permitting the arm support to rotate laterally inward or outward relative to the support frame. In other embodiments, the arm supports may be mounted on a hinged coupling having a locking detent, ratcheting mechanism, or indexed rotational interface that allows discrete angular positions to be selected and retained. In still other embodiments, the inward and outward movement may be provided by a telescoping lateral extension, a sliding carriage guided within a transverse slot or rail, a ball-and-socket joint permitting compound angular adjustment, or a flexible linkage assembly that allows controlled lateral articulation. One or more locking features, such as set screws, cam locks, spring- biased pins, friction clamps, or tool-free knobs, may be provided to secure the arm supports (112a, 112b) in a selected inward or outward position during use. These configurations allow fine adjustment of arm positioning while maintaining structural stability and user support.

[0056] The system (100) may further comprise a balance stability waist belt, body weight support harness or anti-gravity harness (103) for coupling the patient (118) to the frame (103). For example, the anti-gravity harness (103) may be a Maine® anti-gravity body weight support harness. The anti-gravity harness (103) may be coupled to a distal end of force sensors (104a, 104b) by elastic support band rings (102a, 102b). The force sensors (104a, 104b) may be coupled, at a proximal end, to the horizontal support bar (106) by ring connectors (119a, 119b, 119c). The vertical support bars (108a, 108b) can alsoNuer-201-2woinclude side ring connects (120a, 120b) that allow a lateral band to be attached to the body weight support harness (103) to support the torso laterally.

[0057] The system (100) may further comprise a body-weight support harness (103) configured to couple the patient (118) to the frame (103) and provide partial or full unloading of the patient's body weight during therapeutic or rehabilitative activities. In various embodiments, the harness (103) is designed to cradle the patient's torso, pelvis, and / or upper legs in a manner that distributes load across a broad surface area to minimize localized pressure. By way of example, the harness (103) may be implemented as a Maine® anti-gravity body-weight support harness or other commercially available or custom-fabricated harness constructed of reinforced textile materials, composite straps, or padded support panels suitable for repeated load-bearing use. The system may further comprise a balance stability waist belt (not shown) also tethered to the frame vertically and horizontally designed for balance stability and not for full body weight support.

[0058] The anti-gravity harness (103) may be suspended from the frame by one or more force sensors (104a, 104b).. Each force sensor may be coupled at its distal end to the harness (103) via corresponding elastic support band rings (102a, 102b). The elastic support band rings may be formed of elastomeric polymer, braided tensile cord, flexible webbing, or other compliant materials that permit a controlled degree of stretch. This elasticity allows micro-adjustments to the loading on the patient (118), facilitates dynamic movement, and buffers abrupt changes in body position or gait during use. The distal attachment also ensures that forces transmitted to the harness can be measured, regulated, or recorded by the force sensors (104a, 104b). The clasping of the cord or strap can also include a hook and loop capture to secure the closure of the strap.

[0059] At their proximal ends, the force sensors (104a, 104b) may be coupled to the horizontal support bar (106) through a series of ring connectors (119a, 119b, 119c). These ring connectors may comprise welded metal loops, closed-form anchor rings, carabiner-type fasteners, or any structural connecting interface capable of supporting the vertical load applied by the suspended patient. The ring connectors (119a, 119b, 119c) may be positioned at spaced intervals along the horizontal support bar (106) to allow selective vertical alignment of the harness (103) relative to the patient's midline,Nuer-201-2wothereby accommodating patients of different heights, gait characteristics, or therapeutic needs.

[0060] In addition to the overhead suspension components, the vertical support bars (108a, 108b) may include adjustable side ring connectors (120a, 120b) along their lateral surfaces. The side ring connectors (120a, 120b) are configured to receive one or more lateral stabilizing bands, elastic tension bands, or auxiliary restraint straps. When attached to the body-weight support harness (103), these lateral bands can provide side-to-side stabilization, restrict unwanted lateral sway, assist with controlled weight shifting, or create directional resistance beneficial for strength, balance, or gait-training exercises. The arrangement of connectors (120a, 120b) along the vertical support bars permits adjustability in the height and tension of the lateral bands, allowing clinicians to tailor the system to the individual patient's therapy goals and physical condition.

[0061] The system (101) may further include a plurality of adjustable lateral stability rings (150, 152) configured to provide adjustable side-to-side stabilization for the patient during ambulation or therapeutic movement. In the illustrated embodiment, a pair of upper lateral stability rings (150a, 150b) are removably coupled to the vertical bars (108a, 108b) on opposing sides of the frame (101). Each upper lateral stability ring may be mounted using a clamp, cuff, collar, or other mechanical attachment interface that surrounds or partially surrounds the vertical bar and permits secure attachment while still allowing removal or vertical repositioning as needed. The attachment interface may include clamps, enablingthe clinician to adjust the elevation of the lateral stability rings relative to the patient's torso. However, other fasteners such as bolts, threaded knobs, detent pins, or quick-release latches may be used.

[0062] Similarly, lower adjustable lateral stability rings (152a, 152b) are removably coupled to the vertical bars (108a, 108b) beneath the corresponding upper rings. The lower rings may be positioned at or near the patient's hip or pelvis region and may serve as anchor points for lower lateral stability straps, tension bands, or auxiliary side-support elements. Together, the upper and lower lateral stability rings form vertically spaced attachment points that define a lateral stabilization for the user along each side of the frame.

[0063] Each of the lateral stability rings (150a, 150b, 152a, 152b) are configured to mechanically connect to a patient-worn waist belt, torso harness, pelvic harness, orNuer-201-2woother stabilizing garment via a hook, swivel ring, quick-attach buckle, carabiner, or closed-loop connector that allows a tether, strap, elastic band, or lateral support belt to extend between the patient and the corresponding stability ring. In some embodiments, the rings may be rotationally mounted or gimbaled to permit limited angular freedom while restricting excessive lateral excursion of the patient's torso.

[0064] When deployed, the adjustable lateral stability rings maintain the patient in a controlled lateral orientation as they walk or perform therapeutic movements within the stability frame. The stabilizing connection reduces unwanted side-to-side sway, enhances balance support, and assists with gait retraining by guiding the patient along a stable midline path. The placement of the rings at both upper and lower heights allows the clinician to customize the stabilization pattern depending on the patient's mobility status, trunk control, and therapeutic goals. As shown in more detail in FIG.6, the combination of upper and lower lateral stability rings provides a multi-point lateral support system that enhances patient safety and helps maintain proper posture during supported ambulation.

[0065] In embodiments, the upper and lower lateral stability rings (150a, 150b, 152a, 152b) are configured to be vertically adjustable along the length of the vertical support bars (108a, 108b). This adjustability ensures that the patient support system can be customized to accommodate patients of a wide range of heights, body proportions, and clinical needs. Because patients may vary significantly in torso length, pelvic height, and gait mechanics, the ability to reposition the lateral stability rings enables the clinician to align the stabilizing forces with the specific anatomical regions of the patient's body that require support.

[0066] For example, for a taller adult patient, the upper lateral stability rings (150a, 150b) may need to be positioned higher along the vertical bars to align with the patient's midtorso or rib-cage level, while the lower rings (152a, 152b) may be raised to coincide with the patient's pelvis or hip line. In contrast, for a pediatric patient or a smaller adult, the rings may be lowered to ensure proper alignment with the patient's anatomical landmarks. Precise alignment is essential because optimal lateral stabilization occurs when the forces applied through the straps or bands are directed into the correct regions of the torso, thereby promoting an upright posture and reducing the risk of lateral sway or imbalance during ambulation.Nuer-201-2wo

[0067] The vertical adjustability also facilitates progressive rehabilitation. As a patient's strength, balance, and trunk control improve, the clinician may reposition the lateral stability rings to apply greater or lesser stabilizing force, alter leverage points, or gradually reduce reliance on lateral supports. This modularity allows the system to support early-stage, mid-stage, and late-stage gait training within the same frame structure.

[0068] Moreover, the adjustability ensures that the stabilization system remains comfortable, safe, and biomechanically appropriate for each patient. When the rings are positioned at improper heights, the stabilizing straps may apply force to incorrect areas (e.g., the abdomen instead of the torso, or the thigh instead of the pelvis), which can compromise posture, limit gait naturalness, or introduce unsafe pressure points. By enabling upward and downward movement of the rings and cuffs along the vertical bars, the system provides precise, individualized fitment for each patient and allows a single frame design to be used interchangeably for adults, adolescents, and pediatric users.

[0069] Thus, the ability to adjust the lateral stability rings vertically along the support bars is a enhances the versatility, clinical efficacy, and universal applicability of the patient support system.

[0070] With reference now to FIG.2, a top right perspective view of the support device is shown without the harness. As in FIG.1, the device includes a support frame (101) for supporting a patient (118). The frame includes vertical support bars (105a,105b) connected at their upper ends to a horizontal support bar (106) through upper inserts (108a, 108b). At the lower ends of the vertical support bars, lower inserts (114a, 114b) connect the vertical support bars to the base units (160a, 160b), each of which includes wheels (116a, 116b, 116c, 116d). The frame components, including vertical bars (105a, 105b), horizontal bar (106), and base units (160a, 160b), are joined through inserts (108a, 108b, 114a, 114b), which slide into corresponding tubular members to form load-bearing joints. The force sensors (104a, 104b), which are connected at their distal ends through elastic support band rings (102a, 102b). At their proximal ends, the force sensors (104a, 104b) attach to the horizontal support bar (106) via ring connectors (119a, 119b, 119c). The vertical support bars (108a, 108b) also include side ring connectors (120a, 120b) for lateral stabilization attachments.Nuer-201-2wo

[0071] The mid frame inserts (110a, 110b) and left and right arm supports (112a, 112b) are attached to the vertical support bars (105a, 105b) via mid-frame inserts (110a, 110b).Their height is adjustable using arm adjustment holes (122a, 122b).

[0072] In one embodiment, the left and right arm supports are each operatively coupled to, or integrally formed with, a corresponding attachment housing (202a, 202b) configured to removably engage the vertical support bars (105a, 105b). Each attachment housing (202a, 202b) is constructed to slide over, mate with, or mechanically couple to the outer surface of the respective vertical support bar, thereby permitting secure attachment while also enabling vertical repositioning of the arm supports along the length of the support bars. Each attachment housing (202a, 202b) includes a hollow arm portion (204a, 204b). The hollow arm (204a, 204b) defines an internal cavity dimensioned to receive internal mechanical components that facilitate selective engagement with the vertical support bar adjustment holes (122a, 122b). The hollow arm may be cylindrical, rectangular, or other tubular shape, and may be fabricated from metal, reinforced polymer, or other structural material capable of sustaining load from the patient during use.

[0073] Disposed within each hollow arm (204a, 204b) is a shaft (not shown) that is axially movable within the interior cavity. The shaft is operatively connected at its outer end to an exposed pull pin (206a, 206b), which protrudes from the outer surface of the attachment housing (202a, 202b) and is accessible to the user or clinician. The exposed pull pin (206a, 206b) may take the form of a spring-loaded button, a T-pull, a ring-pull, or another manually actuated unlocking mechanism.

[0074] With reference to FIG.3, a top-right perspective exploded view of the support device is shown generally at (300). FIG.3 illustrates the modularity of the frame assembly and the relative positioning of the primary structural and fastening components when separated along their assembly axes. As shown, the device includes a horizontal support bar (106) positioned at the upper portion of the assembly. A series of connector rings (119a, 119b, 119c) are mounted to the horizontal support bar (106) and are shown spaced outward from the bar in the exploded configuration to depict their attachment locations. Each connector ring is secured to the horizontal support bar using corresponding nuts (302), which are shown aligned with their respective attachment apertures.Nuer-201-2wo

[0075] Positioned below the horizontal support bar (106) are the upper inserts (108) are aligned with the open ends of the vertical support bars (105a, 105b). Each insert (108) is shown separated from both the horizontal bar and the vertical bar to illustrate the telescoping or mating relationship when assembled. A corresponding screw(304) and nut (306) are depicted in alignment with the through-holes of insert (108), demonstrating the fastening configuration used to stabilize and secure the interface between the horizontal support bar (106) and the vertical support bars during assembly

[0076] Further downward in the exploded view, the lower inserts (114) are shown positioned between the vertical support bars (105a, 105b) and the lower frame components. These lower inserts serve as connection points for stabilizing and aligning the vertical bars with the base structure. In the exploded configuration, the lower inserts (114) are spaced apart from the vertical bars, with screw (312) and nut (314) illustrated in axial alignment, demonstrating how the lower inserts are secured to provide a rigid, load-bearing joint while remaining separable to preserve system modularity.

[0077] A midline screw (308) and nut (310) are also shown positioned along the central portion of the vertical bar assembly. These components are arranged in the exploded drawing to illustrate how midline fastening points contribute additional structural rigidity and modularity by allowing intermediate segments of the vertical support bar to be joined, detached, or replaced.

[0078] As further shown in FIG. 3, a pair of C-supports (318a, 318b) are positioned between the base structure (160) and the lower regions of the vertical support bars (105a, 105b).In the exploded view, the C-supports are spaced away from the bars to illustrate their role as cross-bracing elements. These supports extend laterally between the vertical bars and the base, providing enhanced torsional resistance and structural stability when assembled.

[0079] At the bottom of the exploded configuration, wheel plates (322) are depicted in alignment with the bottom plate (320), which is configured to receive and retain the wheel assemblies. The wheels (116) are shown separated from the wheel plates, allowing visualization of the positional relationship among the wheel plate (322), bottom plate (320), and the attachment hardware used to mount each wheel assembly to the base units.Nuer-201-2wo

[0080] Overall, the exploded depiction of FIG.3 illustrates the modular architecture of the support device (300), demonstrating how each structural components, horizontal member, vertical bars, inserts, cross-bracing elements, and wheel assemblies, interrelates through corresponding fasteners, screws, nuts, and mating interfaces to create a stable, load-bearing frame upon assembly.

[0081] With reference now to FIG.4, a front view of the device (101) is shown at (400). Like in FIG. 1, the device comprises the device includes a support frame (101) for supporting a patient (118). The frame includes vertical support bars (105a, 105b) connected at their upper ends to a horizontal support bar (106) through upper inserts (108a, 108b). At the lower ends of the vertical support bars, lower inserts (114a, 114b) connect the vertical support bars to the base units (160a, 160b), each of which includes wheels (116a, 116b, 116c, 116d). The frame components, including vertical bars (105a, 105b), horizontal bar (106), and base units (160a, 160b), are joined through inserts (108a, 108b, 114a, 114b), which slide into corresponding tubular members to form load-bearing joints. The force sensors (104a, 104b), which are connected at their distal ends through elastic support band rings (102a, 102b). At their proximal ends, the force sensors (104a, 104b) attach to the horizontal support bar (106) via ring connectors (119a, 119b, 119c). The vertical support bars (108a, 108b) also include side ring connectors (120a, 120b) for lateral stabilization attachments. For orientation, the front side (402a, 402b) of base.

[0082] Referring now to FIG.5, a perspective view of a modular arm support (112a, 112b) is shown generally at (500). Each attachment housing (202a, 202b) includes a hollow arm portion (204a, 204b). The hollow arm (204a, 204b) defines an internal cavity dimensioned to receive internal mechanical components that facilitate selective engagement with the vertical support bar adjustment holes (122a, 122b). The hollow arm may be cylindrical, rectangular, or other tubular shape, and may be fabricated from metal, reinforced polymer, or other structural material capable of sustaining load from the patient during use.

[0083] Disposed within each hollow arm (204a, 204b) is a shaft (not shown) that is axially movable within the interior cavity. The shaft is operatively connected at its outer end to an exposed pull pin (206a, 206b), which protrudes from the outer surface of the attachment housing (202a, 202b) and is accessible to the user or clinician. The exposedNuer-201-2wopull pin (206a, 206b) may take the form of a spring-loaded button, a T-pull, a ring-pull, or another manually actuated unlocking mechanism.

[0084] The interior shaft within the hollow arm is configured such that its inward end is received into, or aligns with, one of the vertical adjustment holes (122a, 122b) formed along the vertical support bars (105a, 105b). When the pull pin (206a, 206b) is released, the shaft automatically extends outward under spring force to protrude into an aligned adjustment hole, thereby locking the arm support assembly at that specific vertical position. This engagement prevents axial movement of the attachment housing relative to the vertical support bar.

[0085] A spring element is positioned within the interior of each hollow arm (204a, 204b).The spring applies a continuous outward biasing force on the shaft, urging the shaft toward the engaged position in which it extends through one of the holes (122a, 122b).The spring may be a coil spring, compression spring, torsion spring, or another resilient biasing component. When the user manually pulls the exposed pull pin (206a) or (206b) (506) in FIG.5, the shaft retracts against the spring force, disengaging from the adjustment hole and allowing the arm support to be moved upward or downward along the vertical support bar. Upon release, the spring forces the shaft outward so that it automatically re-engages with the next aligned vertical adjustment hole.

[0086] The housing (202) has a vertical hollow shaft (502) on a top side and (504) on a bottom side configured to mate with the vertical support bars. This arrangement enables quick, intuitive, and secure height adjustment of the arm supports, allowing the clinician to precisely position the supports to match the patient's arm height, posture requirements, and therapeutic needs. The attachment housing (202a, 202b) and its internal pull-pin assembly thus provide a robust mechanical interface that supports repeated adjustments while maintaining strong lateral and vertical stability during patient use.

[0087] With reference now to FIG.6, a top perspective view of the lateral stability rings (150, 152) is shown generally at (600). The stability rings are removably coupled to the vertical bars for attaching a harness, strap, or other support component to a vertical structural member of the patient harness. The stability rings include a clamp body (602) that forms the main structural portion of the clamp and is shaped to partially encircle the outer surface of a vertical support bar. The clamp body may have a curved or semi-Nuer-201-2wocylindrical interior surface that conforms to the bar and provides a stable gripping interface. A hinged portion (606) is coupled to the clamp body so that the clamp can open and close around the bar. The hinge may be formed by a pivot pin, joint, or integrally molded connection that allows the two portions of the clamp to rotate relative to one another during installation or adjustment. When closed, the free ends of the clamp body and the hinged portion align to permit tightening.

[0088] A wing nut (608) is threaded onto a bolt or screw extending through aligned apertures in both the clamp body and the hinged portion. Rotating the wing nut draws the two portions together, tightening the clamp around the bar and applying inward compression to create a secure friction fit that resists rotation and axial movement. The wing nut configuration allows the clamp to be tightened or loosened without tools so that its position along the vertical support bar can be adjusted quickly by a clinician.

[0089] The clamp assembly further includes an attachment point, such as a ring or loop (604), integrated into the clamp body. This attachment point is positioned so that a harness, lateral stability strap, or other patient-supporting component can be connected directly to the clamp. The ring may be welded, molded, or mechanically secured to the clamp body and may be configured as a fixed ring, a D-ring, or a swivel connector depending on the needs of the system. During operation, the clamp is placed around the vertical support bar, the wing nut is tightened to secure the clamp in place, and the harness or strap is attached to the ring so that forces applied by the patient through the harness are transferred through the clamp into the support frame.

[0090] FIG.7 illustrates a perspective view of the device (101) together with exercise equipment (702) generally at (700). This figure demonstrates the mobility of the device (101) and its ability to be easily integrated with other equipment. In particular, due to the modular construction of the device (101), the overall height of the device may be selectively increased or decreased to fit properly over various types of exercise equipment, including, in this embodiment, a treadmill (702). Such height adjustment may be achieved through the addition of one or more auxiliary components, extension members, or modular inserts, such as the auxiliary piece illustrated in FIG.10, which are configured to couple with existing structural members of the device (101) to extend the vertical reach of the support frame. This allows the device (101) to maintain proper alignment, clearance, and functional positioning relative to the exercise equipmentNuer-201-2woduring use. Additionally, a hanger (704) may have attached to it multiple form factors; in the embodiment shown in FIG. 7, the hanger (704) supports a hang harness (706) configured to attach to a patient.

[0091] With reference now to FIG.8, a perspective view of the patient device (101) in a collapsed state is shown generally at (800). The patient support device (101) is configured to transition from an operational, upright configuration into a compact, folded arrangement suitable for transport or storage. In the folded state, the overall height, width, and depth of the frame are reduced so that the device can be efficiently loaded into a vehicle (802) such as a van or other transport-equipped enclosure. The vertical support bars may include modular sections connected by inserts that allow the upper portions of the bars to be detached, telescoped downward, or folded alongside the lower frame structure. In one configuration, the vertical support bars pivot about a hinge or rotating joint located near the lower inserts so that the upper bar segments swing inward toward the central axis of the frame, thereby minimizing the lateral footprint of the device.

[0092] The horizontal support bar may be removable or collapsible so that, when the vertical support bars are folded inward, the horizontal bar can be detached or pivoted downward to lie parallel with the vertical bars. In embodiments that utilize telescoping elements, the horizontal bar may compress in length, allowing the frame to be shortened without full disassembly. The arm supports may be designed to detach from the mid-frame inserts or rotate downward along the vertical support bars so that they rest alongside the collapsed frame members. The lateral stability rings and their associated cuffs may also be disengaged or folded inward, reducing external protrusions that could interfere with stowing the device in confined spaces.

[0093] At the base of the device, the C-supports and wheel plates may be configured to fold or retract toward the central support region of the frame. The wheels may be positioned to remain in contact with the ground even in the folded configuration, allowing the collapsed device to be wheeled directly into a van or onto a loading ramp. In one embodiment, the base units include hinge points enabling the forward and rearward portions of the base to swing upward into a parallel position relative to the vertical support bars, further reducing the floor footprint of the device. When fully folded, the components may nest together in a substantially planar or low-profile shape, with theNuer-201-2woprimary structural members secured using locking pins, detents, or straps to prevent unintended unfolding during transport.

[0094] In this compact configuration, the device achieves a reduced volume suitable for transport in a standard-size van while maintaining structural integrity and facilitating easy reassembly at the destination. The modular and folding features allow caregivers or clinicians to convert the device from its operational mode into a transportable configuration in minimal time and without the use of specialized tools. The collapsed arrangement also helps protect the functional components, such as sensors, harness connectors, and adjustment mechanisms, by folding them inward toward the frame, thereby minimizing risk of damage during relocation.

[0095] With reference now to FIG.9, a stepwise method of supporting a patient during rehabilitation is illustrated according to an embodiment of the present disclosure.At step 902, a patient support device is provided. The patient support device includes at least two vertically extending support bars, each having an upper end and a lower end, a horizontal support bar extending between the vertically extending support bars at the upper end, and a base unit coupled to each of the vertically extending support bars proximate the lower end. The vertically extending support bars, the horizontal support bar, and the base units collectively form a support frame configured to provide structural stability during rehabilitation activities. In some embodiments, the patient support device is positioned on a supporting surface, such as a clinic floor, treadmill platform, or home environment, and may be rolled into position and secured prior to patient use.

[0096] At step 904, at least two arm supports are operatively coupled to corresponding vertically extending support bars of the support frame. Each arm support may be directly coupled to the vertically extending support bar or coupled via intermediate structures, such as attachment housings or mid-frame inserts. The arm supports may be mounted at initial vertical positions selected based on the anticipated height, posture, or therapeutic needs of the patient, and may be independently coupled to allow asymmetric positioning if desired.

[0097] At step 906, a vertical position of each arm support relative to the support frame is adjusted by repositioning the arm support along the corresponding vertically extending support bar. Adjustment may include moving one or both arm supports upward orNuer-201-2wodownward to align with the patient's upper-extremity height. In some embodiments, the vertically extending support bars include a plurality of vertically spaced adjustment openings, and the arm supports include a locking mechanism configured to selectively engage the adjustment openings, thereby allowing the arm supports to be set at discrete vertical positions. The vertical position of each arm support may be adjusted independently to accommodate asymmetric patient posture or specific therapeutic requirements.

[0098] At step 908, once the arm supports are positioned at the desired vertical locations, the arm supports are secured relative to the support frame. Securing may include engaging a spring-biased pull-lock mechanism or other locking structure to prevent unintended vertical movement of the arm supports during patient use. This securing step ensures that the arm supports remain stable under vertical and lateral loads applied by the patient during rehabilitation activities.

[0099] At step 910, the patient is positioned relative to the patient support device such that at least a portion of the patient's upper body may be supported by the arm supports. The patient may approach the support device from a standing, seated, or partially supported position, depending on the patient's mobility level and therapeutic plan. In some embodiments, a clinician or caregiver assists the patient in positioning their upper extremities on the arm supports, while in other embodiments the patient independently positions themselves using the arm supports for balance and stability.

[0100] At step 912, at least a portion of the patient's upper body is supported on the arm supports while the patient performs a rehabilitation activity. The rehabilitation activity may include, by way of example and not limitation, gait training, balance training, sit-to- stand training, perturbation training, or transitional movement exercises. During this step, the arm supports provide upper-extremity support that assists with balance, posture, and weight shifting while permitting forward, lateral, and rotational movement of the patient relative to the support frame.

[0101] At step 914, one or both arm supports may optionally be adjusted during or between rehabilitation activities. Such adjustment may be performed to accommodate changes in patient posture, fatigue, therapeutic progression, or a change in the rehabilitation exercise being performed, without requiring removal of the patient from the support device.Nuer-201-2wo

[0102] At step 916, the rehabilitation activity is completed. The method may optionally be repeated by repositioning the arm supports, repositioning the patient relative to the support frame, or performing additional rehabilitation activities in subsequent training sessions.

[0103] With reference now to FIG. 10, a perspective view of an auxiliary package (1000) comprising modular auxiliary components that may be selectively installed, removed, or interchanged by a clinician to adapt the device (101) for use with different types of exercise equipment. In the embodiment shown, the auxiliary package (1000) includes a horizontal bar (1002) and a vertical bar (1004) configured to be operatively coupled to the support frame of the device (101). The horizontal bar (1002) may be sized and shaped to be received within corresponding upper inserts (108) of the device, thereby extending or repositioning an upper structural portion of the frame. The vertical bar (1004) may be coupled between structural members of the device to increase an overall height of the device (101), allowing the device to fit over, clear, or align with exercise equipment having varying dimensions, including a treadmill such as that shown in FIG. 7. The auxiliary components of the package (1000) may be secured using releasable coupling mechanisms, including pins, fasteners, locking collars, or tool-free engagement features, such that a clinician can quickly configure the device for a particular exercise environment while maintaining structural stability during patient use.

[0104] FIG. 11 illustrates a perspective view of a storage and transport case (1100) configured to receive and organize auxiliary components of the device (101). In the embodiment shown, the case (1102) includes one or more formed depressions, recesses, or compartments shaped to securely receive auxiliary parts, including components of the auxiliary package (1000), as well as other interchangeable or modular parts of the device. The depressions may be dimensioned to maintain proper orientation of the auxiliary components during storage and transport, thereby reducing movement, wear, or damage. The case (1102) enables a clinician or user to conveniently store, transport, and selectively deploy different auxiliary parts depending on a desired use case, configuration, or type of exercise equipment with which the device (101) is to be used. In some embodiments, the case (1102) may further include labeling, colorcoding, or indicia corresponding to different configurations to facilitate rapid selection and reconfiguration of the device in clinical or rehabilitation environments.Nuer-201-2wo

[0105] FIG. 12 illustrates a perspective view of a storage and transport case (1200) configured to receive and carry a base portion of the device (101). In the embodiment shown, the case (1202) is sized and shaped to accommodate the base of the device (101) in a folded, collapsed, or partially disassembled state. The case (1202) may include one or more internal supports, recesses, or retaining features configured to secure the base of the device (101) during storage or transport. The case (1202) allows the base of the device (101) to be conveniently transported between locations and stored when not in use, while protecting the base from damage. In some embodiments, the case (1202) may be used in combination with the auxiliary component case (1102) shown in FIG. 11, thereby enabling a clinician or user to transport both the base of the device (101) and associated auxiliary components as part of a modular system.

[0106] FIG. 13 illustrates a perspective view of a carrying case (1300) configured to transport the entire device (101). In the embodiment shown, the carrying case (1302) is sized and shaped to receive the device (101) in a modularized, broken-down, folded, or partially disassembled configuration. The device (101) is constructed from modular components that allow a clinician to readily disassemble and pack the device into the carrying case (1302) for transport. The carrying case (1302) may have overall dimensions comparable to those of a medium-sized suitcase, thereby facilitating portability, storage, and transport in clinical, rehabilitation, or home-use environments. In some embodiments, the carrying case (1302) includes one or more wheels and an associated handle, enabling the case to be rolled by a clinician or user. The carrying case (1302) allows the entire device (101) to be conveniently transported between locations while protecting the device components during movement and storage.

[0107] In other embodiments, a clinician or caregiver may manually assist a patient from a seated or partially supported position into a standing posture. Once the patient is stabilized in an upright position, the clinician may guide the patient into the support frame. A body-weight support harness may then be secured at one or more attachment points on the frame to initiate body-weight-supported therapeutic activity. After the patient is secured to the frame, minor adjustments may be made to the harness to improve fit, positioning, and patient comfort. The system may include multiple transfer options and accessories to accommodate patients with differing levels of mobility, strength, and therapeutic requirements.Nuer-201-2wo

[0108] The structural frame of the system may be adjustable in height and width to support a wide range of body sizes and clinical environments. In certain embodiments, the height of the frame may be modified by adding or removing sections of the vertically extending support bars. The vertical support bar sections may be configured to mate using telescoping inserts, interlocking tube segments, pin-and-hole couplings, or other releasable connections that permit adjustment of the vertical dimension in discrete increments. Similarly, the width of the frame may be adjusted by substituting, resizing, or repositioning the horizontal support bar to achieve a narrower or wider stance. This adjustability allows the device to be configured for adult, adolescent, or pediatric users and further accommodates space constraints in clinical, therapeutic, or home-based environments, including positioning the frame over a treadmill.

[0109] To assemble the patient support device, the horizontal support bar may be coupled to the vertically extending support bars using upper inserts. Arm supports may be mounted to the vertically extending support bars at an upper level, and upper vertical support bar sections may be coupled to mid-frame insert locations and lower vertical support bar sections. The lower vertical support bar sections may then be coupled to base units positioned on opposite sides of the support frame. The frame components may be secured using bolts, nuts, or other fastening elements. One or more chains, straps, or cloth or canvas tethers may be coupled to attachment rings on the frame and connected to force sensors and the body-weight support harness. In some embodiments, the patient may be lifted into position using a manual or electric winch, a sit-to-stand frame accessory, or a tug bar and strap assembly that allows the patient to assist with standing using upper-extremity strength prior to transfer into the bodyweight support harness. In other embodiments, the clinician or caregiver may manually assist the patient into a standing position before transferring the patient into the bodyweight support harness. The height and width of the frame may be adjusted as needed by adding or removing vertical support bar sections or modifying the horizontal support bar, thereby allowing the device to be configured for adult or pediatric use.
