The present disclosure generally relates to systems and accessories associated with an exoskeleton; and in particular, to a system/apparatus for storing, use in therapy, and transporting a (bionic) exoskeleton.
The use of exoskeletons (e.g., bionic, powered, etc.) in the application of physical therapy for paraplegic and otherwise physically disabled patients is a burgeoning practice. However, bionic exoskeletons can be heavy and awkward in shape, making them difficult to store, bring out, and put away between physical therapy sessions. In addition, bionic exoskeletons can be very expensive and must be easily portable, as many facilities may only have access to a few exoskeletons to be used across many patients. During physical therapy sessions, the current practice is to store the exoskeleton using any means possible, including the use of office chairs and wheelchairs. However, these simple chairs are easily torn or broken by the heavy metallic frame of the exoskeleton, and the cumbersome limbs of the exoskeleton can make it difficult to store or carry the exoskeleton.
It is with these observations in mind, among others, that various aspects of the present disclosure were conceived and developed.
Corresponding reference characters indicate corresponding elements among the view of the drawings. The headings used in the figures do not limit the scope of the claims.
Various embodiments of an apparatus for storage and transportation of an exoskeleton, including an associated system and methods thereof are described herein. In some embodiments, the apparatus includes a frame comprising a plurality of legs, a seat, and a back which are operable for being moved between one or more configurations. The seat of the frame defines a seat surface configured for engagement with an exoskeleton. Furthermore, the back of the frame is operably engaged with the seat such that the back of the frame may be folded over, into, or extended from the frame to reduce an overall profile size of the apparatus in a collapsed or folded configuration. Some embodiments of the apparatus may further include a pair of footrests defined along the legs that rotate in a lateral direction relative to the frame for the patient's ease of transition into the exoskeleton. In other embodiments, the footrests may be positioned/foldable along the legs in a manner so as not to interfere with the positioning of the exoskeleton or inhibit the movement of the exoskeleton while in use with the person or in transition to and from the exoskeleton. In some embodiments the frame includes a locking mechanism that locks or transitions one or more of the aforementioned components of the frame to or from a storage configuration or a ready configuration. In addition, the frame is operable for storing itself or the exoskeleton in a compact and portable position in a “transport” configuration or for bearing the weight of a patient and the exoskeleton as the patient is able to sit in the exoskeleton while the exoskeleton engaged to the frame in a “sit-to- and-from-stand” configuration.
Use of exoskeletons has gained considerable popularity in assisting patients with lower-limb paralysis through gait therapy and related methods. To operate, exoskeletons require a surface for patients to go unencumbered from a sitting position to a standing position. Transport and storage of exoskeletons is paramount. At present, clinicians generally use basic chairs for both transport and storage of the exoskeletons. However, there are various known chair-exoskeleton compatibility issues which result in damage to the chair and/or the exoskeleton. In addition, technology is lacking or insufficient that would potentially accommodate transport and storage of an exoskeleton, and also assist the patient generally with movement from the sitting position to the standing position. Accordingly, clinicians have limited options available with respect to technology sufficient to meet the subject needs associated with exoskeletons and use thereof.

As further indicated, a plurality of legs 108, designated leg 108A and leg 108B, may extend from the base 104 along a side of the base 104 opposite the back 106. In general, the plurality of legs 108 may define elongated members separating a ground surface from the base 104. The plurality of legs 108 may include one or more legs, and may take the form of any variety of shapes suitable for positioning the base 104 a predetermined height (which may be adjustable) above the ground/surface, and suitable for supporting a predetermined exoskeleton weight, and possibly a weight of a human in combination with the weight of an exoskeleton. The plurality of legs 108 are shown as discrete members; however it is contemplated that a single contiguous leg component may be employed for some applications.
The apparatus 100 may include various forms of a footrest assembly 110 depending upon the exoskeleton/for which it is intended. In some embodiments, a footrest 110A is defined, in communication with, or otherwise positioned along the leg 108A opposite the base 104; and a footrest 1108 is defined, in communication with, or otherwise positioned along the leg 108A opposite the base 104. Alternatively, however, the footrest assembly 110 may include a contiguous single member horizontally aligned along the plurality of legs 108 (which may fold up vertically). The shape and form of the footrest assembly 110 may be modified to accommodate different exoskeleton forms.
The apparatus 100 further includes a motion mechanism 112 for movement along a ground surface. In some embodiments, the motion mechanism 112 is defined by a plurality of wheels, such as wheel 112A positioned along the bottom of the footrest 110A, and wheel 112B positioned along the bottom of the footrest 1108 (or a total of three or more wheels, where the plurality of legs is greater than two). While wheels are depicted, the motion mechanism 112 may include, by non-limiting examples, caterpillar tracks, pedrail wheels, spheres, a sled or travois, and any other such wheel alternatives. A locking mechanism (not shown) may be integrated with the motion mechanism 112 to impede movement of the apparatus 100 when desired. For example, a brake assembly (not shown) or other such device may be implemented so that when engaged the wheel 112A and the wheel 112B are each prevented from rotating to temporarily maintain the apparatus 100 in a fixed position along a surface (to, e.g., facilitate removal of an exoskeleton therefrom, or enable a person to sit along the base 104 to engage an exoskeleton). A step button or lever (not shown) may further be integrated along the apparatus 100 to engage/disengage the wheel 112A and/or the wheel 112B.
As further shown, the apparatus 100 may include any other components that may facilitate transportation and storage of an exoskeleton, including, but not limited to a storage compartment 114 for storing removable portions of an exoskeleton or tools for assembly thereof, a handle 116 for guiding movement of the apparatus along a surface, and the like. A cushion material, which may be tear-resistant (not shown), may be mounted along the base 104 and the back 106 to provide comfort to an individual utilizing the apparatus 100 to don an exoskeleton.
In some embodiments, the apparatus 100 may include any number of joints or hinges (not shown) to facilitate manipulation of the apparatus to a folded or collapsed configuration. For example, the back 106 may be configured to fold flat along the base 104, and the legs 108 may be configured to fold along the bottom of the base 104 opposite the back 106. In addition, the footrest assembly 110 may be foldable relative to the plurality of legs 108 (e.g., the footrest 110A may fold up along the leg 108A).
In the configuration shown, the apparatus 100 may define a general chair/wheelchair shape configuration. However, the apparatus 100 may include any number or arrangement of configuration change components 118 such as electric motors, pneumatics, levers, hydraulics, or actuators to facilitate movement or rotation of the components of the apparatus 100 relative to one another. For example, in some embodiments, the plurality of legs 108 (and/or the height/length of the apparatus 100 generally) may be extendable and/or retractable using any number of actuators, mechanically, and/or electromechanically, or the configuration change components 118 may be engaged to rotate the base 104 relative to the back 106 to aid with seating of an individual along the apparatus 100. The configuration change components 118 may include electrical components interconnected by any number of conductive members (not shown), or the configuration change components 118 may be devoid of electrical components to reduce the weight and complexity of the apparatus 100 and/or facilitate folding.
Numerous related features are contemplated. For example, the apparatus 100 may comprise aluminum, titanium, composites, carbon fiber, or any number or combination of such materials to provide a lightweight yet durable structure. In some embodiments, aspects of the apparatus 100 may be formed using tubing (e.g., Comodita Brava rollator tubing) with an internal support, such as an I-beam. A seat cover may be formed along the apparatus 100 and may comprise Dyneema fabric or other similar material, and may be replaceable. In general, the apparatus 100 is configured to support at least a 220 pound person and an exoskeleton ranging from 10 to 100 pounds.
As further shown in
The exoskeleton 101 is not limiting and may include any number of electric motors, pneumatics, levers, hydraulics, actuators, or electrical/mechanical/electro-mechanical components to accommodate movement of the limbs of the device. The exoskeleton 101 may also include additional structural features such as a thigh brace, interface devices, or other such components. The shape and configuration depicted is merely exemplary.

In some embodiments, the seat 204 rests at the upper end 221A of each of the plurality of legs 202 and comprises a seat frame 250, wherein the seat frame 250 defines a front section 251, a rear section 252, a seat surface 256 and a seat underside 257, where the seat surface 256 is operable to receive an exoskeleton in the “sit-to-stand” or “display” configurations. In some embodiments, the seat 204 is 18 inches deep and 22 inches wide, and may be adjustable to accommodate different exoskeletons. In addition, the back 206 of the apparatus 200 is operably engaged with the rear section 252 of the seat frame 250. The back 206 comprises a back frame 260 defining a front surface 261 and a rear surface 262, wherein the front surface 261 engages with the exoskeleton in the “sit-to-stand” and “display” configurations and the rear surface 262 is operable to store extraneous exoskeleton hardware.
In some embodiments, the back 206 of the apparatus 200 further comprises a pair of handles 264 for pushing the apparatus 200 in the “sit-to-stand”configuration or in the “transport” configuration. In some embodiments, an additional handle (not shown) may be included on the apparatus 200 such that the apparatus 200 may be lifted and carried. The apparatus 200 may also include a locking mechanism (not shown) disposed along the back frame 260 or the seat frame 250 for locking the components of the apparatus 200 in the “transport” configuration, the “sit-to-stand” configuration, the “display” configuration, or any other configuration. In some embodiments, the back 206 of the apparatus 200 may further include a pouch or other form of storage compartment to store various tools or accessories for the apparatus 200.
In some embodiments, the back 206 and the seat 204 comprise a plurality of eccentric spaces 242 formed along the front surface 261 and the seat surface 256. The plurality of eccentric spaces 242 are configured to provide clearance for any protruding parts of the exoskeleton while the seat surface 256 and front surface 261 provide support for the exoskeleton. In some embodiments, one or more retention belts (not shown) may be included on the back 206 or the seat 204 of the apparatus 200 in order to strap the exoskeleton onto the apparatus 200. The seat surface 256 of the seat 204 or the front surface 261 of the back 206 may be comprised of a sturdy material much like carpet or vinyl to provide a non-slip surface that resists tearing and retains the shapes of the eccentric spaces 242. In other embodiments, the seat surface 256 of the seat 204 or the front surface 261 of the back 206 may be comprised of hard molded plastic. The seat surface 256 of the seat 204 or the front surface 261 of the back 206 may be easily removable from the seat frame 250 or the back frame 260 for replacement in case the seat surface 256 or the front surface 261 become damaged over time. In some embodiments, the frame 201 may be configured to support at least a 300-lb person plus the exoskeleton (usually about 50-100 pounds) in order to allow both the patient and the exoskeleton to safely be supported by the apparatus 200.
The frame 201 may further include a plurality of hinges (not shown) and the locking mechanism installed along the various components of the frame 201 in order to fold the back 206, the seat 204 and the legs 202 into the different configurations. In some embodiments, the frame 201 may be folded into the “transport” configuration when the additional handle is lifted. In other embodiments, the frame 201 may be wheeled around in the “sit-to-stand” configuration using the handles 264 and the wheels 203 with or without the exoskeleton. The “sit-to-stand” configuration also allows the brakes 222 to engage thereby allowing a patient to sit in the exoskeleton on the apparatus 200 while the brakes 222 are engaged. The “display” configuration may be any configuration of the components of the apparatus 200 which stands the exoskeleton up or seats the exoskeleton for display. Lastly, the “transport” configuration may also allow the components of the apparatus 200 to be folded into them such that a total volume of the apparatus 200 and exoskeleton are reduced or formed into a shape which is easy to store.

As indicated, a plurality of legs 308 extends from the base 302 and generally interconnects the base 302 with the seat 304. In other words, the seat 304 is mounted to the plurality legs 308 opposite the base 302 such that the plurality of legs 308 suspends the seat 304 over the base 302 in a deployed or storage configuration. In some embodiments, a joint 310 such as a hinge or hinge portion of the seat 304 connects the back 306 with the seat 304 so that back 306 can rotate about the joint 310 relative to the seat 304 or vice versa (as indicated in
In some embodiments, each of the plurality of legs 308 defines an elongated member comprising at least two sections shown as 312A and 312B in communication with and bendable/foldable about a joint 314, such as a hinge. In particular, the section 312A extends from the base 302 and is interconnected, via the joint 314, with the section 312B that is coupled to the seat 304. In a deployed or seated configuration as is shown in
As further shown, the first section 312A defines a first terminal end 316A of each of the plurality of legs 308 coupled to the base 302, and the second section 312B defines a second terminal end 316B of each of the plurality of legs 308 coupled to the seat 304. In some embodiments, the apparatus 300 is configured such that the first section 312A may be folded relative to the second section 312B along the joint 314, to bring the second terminal end 316B closer to the first terminal end 316A (to e.g., assume a folded or transport configuration). This action may be reversed in the event it is desired to move the seat 304 to a position farther way from the base 302, for whatever reason. Intuitively, the angle A changes as the position of the second terminal end 316B is changed relative to the position of the first terminal end 316A. The plurality of legs 308 may take the form of any variety of shapes suitable for positioning the seat 304 a predetermined height (which may be adjustable) above the ground/surface, and suitable for supporting a predetermined exoskeleton weight, and possibly a weight of a human in combination with the weight of an exoskeleton. The plurality of legs 308 may include any number or type of individual discrete sub-members foldable relative to one another along any number of hinges or other joints; however it is contemplated that a single contiguous member component may be employed for some applications.
As further shown in
In a deployed or storage configuration, the back 306 extends perpendicularly from the seat 304 as shown, and the plurality of legs 308 are at least partially unfolded to suspend the seat 304 over the base 302 and so that the apparatus 300 may support a trunk or frame of an exoskeleton. In some embodiments, the base 302, seat 304, and the back 306 may define a general rectangular shape, and may be at least partially planar to accommodate engagement with various components of an exoskeleton. Other shapes are contemplated depending on the functionality of the apparatus 300 and how the components of the apparatus 300 engage or fold.
