Description

HYBRID MONOCOQUE AMBULATION AID

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This patent claims the benefit of priority to U.S. Provisional Application No. 63/437,513, filed on January 6, 2022, entitled “Hybrid Monocoque Ambulation Aid,” which is incorporated herein by reference in its entirety for all purposes.

BACKGROUND

[0002] A range of ambulation aids have been developed over the many years since these devices were first introduced. These devices are used to assist people in the act of walking or standing by providing weight bearing and/or balance assistance. Historically, the basic construction method has changed little, with the vast majority being constructed of extruded metal tubing. A smaller percentage of devices have been constructed of assembled polyvinyl chloride (PVC) plumbing pipe, hydroformed metal, or occasionally injection molded polymer parts.

[0003] In either case, multiple pieces (e.g., multiple tubes) must be assembled to create a frame on which one or more supports can be provided to aid in user mobility. Such tubular framebased assemblies are complex to manufacture and assemble and suffer from multiple joinders and other contact points. Additionally, the tubular frame creates an undesirable aesthetic. Further, an excessive amount of time and multiple processes may be required in assembly.

[0004] Current construction techniques only offer a limited range of engineering and design flexibility. This is due to the nature of the materials used, as well their method of manufacturing and construction. Designs based on tubular materials are limited by factors such as the availability of stock materials, bend radii of the tubes, how the tubes are joined at intersections, weight of the tubes, strength of the tubes, the overall shape and form of the cylindrical materials, etc. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION OF CERTAIN EXAMPLES

[0021] Certain examples provide an ambulation aid, otherwise referred to as a rollator or walker. Certain examples provide a lightweight, stable, and sturdy ambulation aid that supports user body weight, enables user mobility, is easy to maneuver, and is easy to lift, carry, and store. Certain examples provide method of manufacturing the ambulation aid. Certain examples enable a user to walk within the frame of the ambulation aid, rather than behind the ambulation aid (as in traditional walker designs), improving stability and comfort while reducing a risk of falling. Certain examples provide additional functionality to a user beyond the capabilities of a traditional metal tubular walker.

[0022] In the following detailed description, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration specific examples that may be practiced. These examples are described in sufficient detail to enable one skilled in the art to practice the subject matter, and it is to be understood that other examples may be utilized. The following detailed description is therefore provided to describe one or more example implementations and not to be taken limiting on the scope of the subject matter described in this disclosure. Certain features from different aspects of the following description may be combined to form yet new aspects of the subject matter discussed below.

[0023] The figures are not necessarily to scale. Instead, the thickness of the layers or regions may be enlarged in the drawings. In general, the same reference numbers will be used throughout the drawing(s) and accompanying written description to refer to the same or like parts. As used in this patent, stating that any part (e.g., a layer, film, area, region, or plate) is in any way on (e.g., positioned on, located on, disposed on, or formed on, etc.) another part, indicates that the referenced part is either in contact with the other part, or that the referenced part is above the other part with one or more intermediate part(s) located therebetween. Connection references (e.g., attached, coupled, connected, and joined) are to be construed broadly and may include intermediate members between a collection of elements and relative movement between elements unless otherwise indicated. As such, connection references do not necessarily infer that two elements are directly connected and in fixed relation to each other. Stating that any part is in

“contact” with another part means that there is no intermediate part between the two parts.

[0024] Descriptors “first,” “second,” “third,” etc., are used herein when identifying multiple elements or components which may be referred to separately. Unless otherwise specified or understood based on their context of use, such descriptors are not intended to impute any meaning of priority, physical order or arrangement in a list, or ordering in time but are merely used as labels for referring to multiple elements or components separately for ease of understanding the disclosed examples. In some examples, the descriptor “first” may be used to refer to an element in the detailed description, while the same element may be referred to in a claim with a different descriptor such as “second” or “third.” In such instances, it should be understood that such descriptors are used merely for ease of referencing multiple elements or components.

[0025] “Including” and “comprising” (and all forms and tenses thereof) are used herein to be open ended terms. Thus, whenever a claim employs any form of “include” or “comprise” (e.g., comprises, includes, comprising, including, having, etc.) as a preamble or within a claim recitation of any kind, it is to be understood that additional elements, terms, etc. may be present without falling outside the scope of the corresponding claim or recitation. As used herein, when the phrase “at least” is used as the transition term in, for example, a preamble of a claim, it is open-ended in the same manner as the term ’’comprising” and “including” are open ended. The term “and/or” when used, for example, in a form such as A, B, and/or C refers to any combination or subset of A, B, C such as (1) A alone, (2) B alone, (3) C alone, (4) A with B, (5) A with C, (6) B with C, and (7) A with B and with C. As used herein in the context of describing structures, components, items, objects and/or things, the phrase “at least one of A and B” is intended to refer to implementations including any of (1) at least one A, (2) at least one B, and (3) at least one A and at least one B. Similarly, as used herein in the context of describing structures, components, items, objects and/or things, the phrase “at least one of A or B” is intended to refer to implementations including any of (1) at least one A, (2) at least one B, and (3) at least one A and at least one B. As used herein in the context of describing the performance or execution of processes, instructions, actions, activities and/or steps, the phrase “at least one of A and B” is intended to refer to implementations including any of (1) at least one A, (2) at least one B, and (3) at least one A and at least one B. Similarly, as used herein in the context of describing the performance or execution of processes, instructions, actions, activities and/or steps, the phrase ”at least one of A or B” is intended to refer to implementations including any of (1) at least one A, (2) at least one B, and (3) at least one A and at least one B.

[0026] As used herein, singular references (e.g., “a”, “an”, “first”, “second”, etc.) do not exclude a plurality. The term “a” or “an” entity, as used herein, refers to one or more of that entity. The terms “a” (or “an”), “one or more”, and “at least one” can be used interchangeably herein. Furthermore, although individually listed, a plurality of means, elements or method actions may be implemented by, e.g., a single unit or processor. Additionally, although individual features may be included in different examples or claims, these may possibly be combined, and the inclusion in different examples or claims does not imply that a combination of features is not feasible and/or advantageous.

[0027] As used herein, the terms “system,” “unit,” “module,”, “engine,”, “component,” etc., may include a hardware and/or software system that operates to perform one or more functions. For example, a module, unit, or system may include a computer processor, controller, and/or other logic-based device that performs operations based on instructions stored on a tangible and non-transitory computer readable storage medium, such as a computer memory. Alternatively, a module, unit, or system may include a hard-wires device that performs operations based on hard-wired logic of the device. Various modules, units, engines, and/or systems may represent the hardware that operates based on software or hardwired instructions, the software that directs hardware to perform the operations, or a combination thereof, such as to manufacture various implementations of the example ambulation aid shown and described herein.

[0028] In certain examples, the ambulation aid provides improved stability, mobility, and functionality over previous walker designs. For example, with a traditional rolling walker, its fixed seat forces a user to walk behind the seat with their spine forward and bent, leaving the user in a hunched over position. Certain examples provide an ambulation aid with a stow-away seat to open space within the walker to allow the user to walk inside the walker, aligning the spine and enabling the user to walk upright, reducing back and neck pressure by up to 60%. Additionally, through a wheeled design and allowing the user to stand within the span of the ambulation aid, a zero-degree turn radius is provided, enabling maneuverability into tight spaces, around corners, quicker reaction to obstacles, etc. Also allows for reducing the distance a user must reach over a walker when trying to access a countertop or sink, often resulting in the user dangerously putting their walker to the side to reach what they need and leaving them without the surrounding support of their walker. A brake further enables the ambulation aid to be readily controllable on inclines, when faced with obstacles, etc. Additional features can include cup holder(s), a movable tray, a storage compartment, etc.

[0029] Certain examples provide a hybrid ambulation aid. For example, a first portion and a second portion can form the hybrid ambulation aid. In certain examples, at least one of the first and second portions is formed in monocoque construction (e.g., structural skin, skin integral with the body, etc.). In some example, the first portion is a bottom portion or frame formed in monocoque construction, and the second portion is a top or upper portion made of a material, such as a rigid material, a shock-absorbing material, a shock-absorbing material on top of a rigid material, etc., in monocoque, unibody, and/or other construction (e.g., a molded box covered in a layer of foam, a cloth or other fabric container, etc.).

[0030] Certain examples provide a hybrid monocoque ambulation aid. The hybrid monocoque ambulation aid is a mix of different monocoque materials. For example, a bottom portion of the ambulation aid is a first material forming a rigid monocoque frame while a top portion is a second, shock-absorbing monocoque material. The top portion and the bottom portion fit together to form a hybrid monocoque ambulation aid. The example multi-part (e.g., two-part, etc.) design enables the ambulation aid to provide support and protection for a user. The example multi-part design provides a modular construct that isolates portions providing different functionality and structure to form the resulting hybrid ambulation aid.

[0031] For example, the two-part hybrid monocoque ambulation aid isolates i) a support member of more rigid material that drives mobility and load-bearing support for a user from ii) a protective member of shock-absorbent, softer material to ease interaction with the user (e.g., for ease of gripping, protection against impact of collision or fall, etc.). The rigid, load-bearing member, section, or portion mates with the softer, protective member, section, or portion to form an integrated ambulation aid providing a combination of stability, mobility assistance, and protection to a user.

[0032] In certain examples, the first, more rigid material forms a bottom frame. The softer, protective material forms a top that connects to the bottom frame to form the ambulation aid.

[0033] In certain examples, the bottom frame can fold up for storage and transport, for example. The bottom frame can include a folding mechanism such as a locking hinge that locks in place when the ambulation aid is in an open position. When locked in the open position, the hinge and/or other folding mechanism helps enable the bottom frame, alone or in conjunction with the top portion, to provide mobility and/or support to a user. The hinge and/or other folding mechanism can be released by a user to fold up the ambulation aid. In certain examples, the folding mechanism is a locking mechanism that also provides a locking position when folded to keep sides of the ambulation aid locked in a folded position, which can be released by the user. The folding and/or locking mechanism can be formed using, for example, one or more cables, rigid connections, living hinges, spring loaded pins, etc.

[0034] In certain examples, the top or upper portion is made of softer material(s) than the bottom portion. In other examples, the top or upper portion is made of the same or similar material as the bottom portion. The top portion can accommodate one or more accessories, such as a seat, storage compartment, storage compartment door, a food and drink tray, a cup holder, an umbrella hook, etc. The softer material of the top portion can also include a “landing” or support area for a fold out seat (e.g., including a locking mechanism to positively engage the seat with the rest of the ambulation aid when folded out/opened/extended). When folded up and/or otherwise stowed away/stored, the seat can be positively engaged to keep the seat out of the way of the user and facilitate a more upright walking posture in the ambulation aid. That is, a user can walk more inside the ambulation aid, rather than behind the ambulation aid, hunched over to avoid the seat.

[0035] In some examples, the seat is fixed, rather than foldable. In other examples, no seat is provided in the ambulation aid. By removing obstacles, protrusions, extensions, etc., within the ambulation aid, a user can walk more upright and reach over the ambulation aid more effectively and easily compared to fixed seat designs. The compact design also facilitates a tighter turning radius compared to fixed seat designs.

[0036] In one example, the seat is removably connected to a storage door in the ambulation aid (e.g., in the top portion and/or the bottom portion of the ambulation aid), and the seat and storage door can be disconnected and utilized independently. The seat can be connected to the storage door using dual point, spring loaded pins actuated from a central lever, for example. Many other options are available for this functionality, including retention levers, hook and loop technology, magnets, ball in socket, living hinges, spring loaded latches, etc.

[0037] In certain examples, the seat can be formed of a soft material, rigid material, fabric, mesh, webbing, etc. In certain examples, the landing area for the seat can be formed of softer material, such as the same as or similar to the top portion. In other examples, the landing area for the seat can be provided by and/or integrated into the more rigid material of the bottom portion or frame. Alternatively, a seat supported by straps, cables, and/or other linkages when the seat is folded out for use, for example. In certain examples, the seat can include a storage pouch, such as a zippered storage pouch formed under the seat, etc.

[0038] In certain examples, at least part of the upper portion is formed as a convenience module, which can be removably attached and detached from the lower portion or frame of the ambulation aid. The convenience module can include a tray, storage compartment, and seat, or subset thereof, for example. The convenience module may be bundled with the frame to be used with the frame, removed for separate use, removed for use of the frame alone, etc.

[0039] In certain examples, color panels can be applied and/or embedded in the softer material to provide aesthetic and/or functional benefits. In certain examples, the top portion can be colored. Some or all portions of the ambulation aid can be covered with panels and/or other material for functional (e.g., shock-absorbing thin foam, etc.) and/or decorative purposes, for example. As an example, the top portion can be molded out of thin, colored plastic to which a coating or covering is applied (e.g., shock-absorbing thin foam, etc.). In certain examples, panels applied and/or embedded in the top portion and/or the bottom portion can be impact- and/or wearresistant. For example, when the top portion is formed of a softer material, panels can be applied and/or embedded in the softer material of the top portion to increase impact- and/or wearresistance of the top portion. Solar panels can be provided to enable power to and/or charging of devices such as phones, tablets, lights, etc. In certain examples, “windows” or openings in the more rigid frame (e.g., the bottom portion) can be filled with decorative and/or functional inserts.

[0040] In certain examples, areas of the ambulation aid can accommodate a range of accessories, including lights, storage organization, cane holders, solar panels, etc.

[0041] In certain examples, handlebars can be adjustable, seat height can be adjustable, height of the ambulation aid can be adjustable, etc. [0042] In certain examples, the top portion can be packaged separately from the bottom portion, and the ambulation aid can be assembled by the user. For example, the top and bottom portions can be assembled using a one-time snap-together fit. Alternatively, the top and bottom portions can be removably connected to allow the user to remove the storage compartment for separate use, for example. In certain examples, other components, accessories, etc., can be permanently and/or reversibly engaged to the ambulation aid body (e.g., upper portion and/or lower portion). For example, handles, wheels, brakes, etc., can be packaged and/or shipped separately and be inserted/connected/installed in the respective top and/or bottom portion when assembled for use.

[0043] Examples of materials and processes that can be used to form the top/upper portion, the bottom/lower portion, accessories, other elements, etc., in monocoque construction (e.g., structural skin, skin integral with the body, etc.) include steam chest molded particle foams (e.g., expanded polypropylene), other polymers, other types of reactive foams, blow molding, rotomolding, gas-assisted injection molding, injection molded polymers or metals, structural foam, chemically foamed injection molded polymer, carbon fiber chop or layup, fiberglass chop or layup, compression molded materials, etc. Additionally or alternatively, computer numerical control (CNC) can be used to form materials of foam, polymer, etc. Hydroformed aluminum, twin and/or single sheet thermoforming, metal casting, metal stamping, twin sheet metal welded metal stampings, die casting, etc., are other potential options. Other processes available for similar materials include spin molding, silicone molding, plastic and/or metal welding. The polymers mentioned above can also include specific fillers, such as glass, carbon fiber, talc, etc., to facilitate different properties of the monocoque component. For example, hollow glass spheres (e.g., microspheres) and/or other filler/strengthener material can be embedded in an injected molded polymer material, chemical foaming agent, physical foam injection, etc. to form a part. Additive manufacturing such as three-dimensional (3D) printing, bonded particles, ultraviolet (UV) fused material, laser sintered materials, etc., utilizing a variety of materials can also be used. Various rubbers and variants of the same can also be utilized, along with wood-based materials. Ethylene- Vinyl Acetate (EVA) foam injection molding is another option, among others, for example.

[0044] For example, one or more monocoque elements can be formed of foam or a foam- like material that is generated from a plurality of air-infused particles. The body of the ambulation aid provides integral support for a user through the ambulation aid body, rather than traditional, multi-segmented walker design. In certain examples, the ambulation aid body is formed using a manufacturing process such as a molding process (e.g., steam chest molding, etc.), which forms the ambulation aid body from a collection of air-infused particles.

[0045] For example, using a steam-chest molding process, the ambulation aid can be formed from a plurality of molded beads, balls, spheres, and/or other particles, such as expandable polystyrene (EPS), expanded polyethylene (EPE), expanded polypropylene (EPP), expanded polylactide (EPLA), expanded thermoplastic polyurethane (ETPU), etc. These air-infused particles (e.g., spheres, may expand or maintain their size under heat and pressure, for example. Some such particles may be formed with internal pressure to assist in fusion of particles to form an integral part via a manufacturing process such as steam-chest molding, etc. Steam-chest molding is a manufacturing process to form a foam or foam-like structure from a plurality of balls or beads (also referred to as air-infused particles or particles having entrapped air) that are placed in a receptacle or mold at a certain volume and treated with steam.

[0046] An example mold includes vents integrated into the surface(s) of the mold to facilitate introduction and evacuation of steam, pressure, etc. The mold can be associated with injectors to provide particles, steam, pressure, etc., and ejectors to eject the part after molding is complete. In certain examples, the formed part can be cured in an oven or other heated chamber.

[0047] In operation, the steam transforms the particles into a combinable state. For example, the steam can cause the particles to expand under vacuum and pressure. The steam heats the particles into a fusable state, for example. Pressure can be applied to fuse the particles into an integral foam/foam-like part. Vacuum is used to extract air and steam that may otherwise cause unwanted bubbles or pockets to form in the part. In certain examples, steam, pressure, and/or vacuum is applied to a mold in both directions to help ensure intended bead/particle fusion and/or expansion into the formed part.

[0048] Pressure applied to the heated, and sometimes expanded, particles (e.g., compressible beads) can vary based on a desired density of the resulting integral part. For example, lighter pressure results in a less dense foam or other air-infused material, while heavier pressure forms a more dense structure. In other examples, density is determined by the construction, composition, and/or size of the starting particle.

[0049] In certain examples, molding may include variable density to form portions or areas of different density in the same part. The configuration of the part for variable densities can be based on a load-bearing analysis, etc. For example, regions of the part are temporarily separated as the regions are processed. Each region is associated with a different desired density, which can be achieved through different material, different particle concentration, different pressure, etc. After processing each region, the regions are fused together into one part within the same molding operation. As such, the part can be more precisely formed to include areas of greater and lesser strength depending upon the configuration of the part. Such variable density results in savings of material, cost, and part weight while increasing part utility and function.

[0050] In certain examples, pressure applied in the mold to form the integral part also creates a barrier or “skin” on the exterior portion of the foam other air-infused material (e.g., the part(s) of the material contacting the interior surface of the closed mold). The skin provides a barrier against the entry of moisture into the formed part and provides added rigidity to the integral part without necessitating a coating of additional material, for example.

[0051] In certain examples, the formed part is cooled (e.g., by introducing cooling water or air into the mold to cool and cure the formed part, by cooling the mold itself, etc.). Pressure can be maintained until the part is cured to avoid unwanted expansion or bloating of the part during cooling and curing. If cooling liquid is used, that cooling liquid is ejected from the mold, and then the formed part can be ejected or otherwise removed from the opened mold. In certain examples, molds can be heated to maintain temperature in between cycles of the molding process, which reduces cycle times to prepare and maintain the mold.

[0052] In certain examples, components can be integrated into the body of the ambulation aid as part of the steam-chest molding process. In certain examples, reinforcements, stiffening materials, attachment points, and/or other elements (referred to as inserts), can be positioned in the mold/receptacle before the beads are introduced. As the material expands and/or otherwise combines under steam and pressure, the air-infused material forms around the elements inserted in the mold. As such, an attachment point for a tray, seat, handle, etc., can be integrated into the body of the ambulation aid in the steam-chest molding process, for example.

[0053] In certain examples, elements can be incorporated into the body/panels of the ambulation aid to lighten/reduce weight while maintaining and/or adding support. For example, fillers/strengtheners with a density lower than the polymer/plastic used to form body panels can help strengthen the part while reducing weight. In certain examples, hollow spheres (e.g., microspheres, etc.), talc, paper pulp, etc., can be mixed in to reduce weight and increase stiffness and/or strength. Foaming (e.g., chemical foaming, “physical foaming” such as the injection of gas to generate bubbles and form a foam, etc.) can be used to form panels with integrity yet reduced weight.

[0054] Carbon fiber, glass, other fiber, etc., can also be introduced as a lightweight, strong filler. Some fiber can include a specific cross-section desired to enhance their binding to the carrying polymer, for example. Alternatively or additionally, some fiber can include a surface treatment to enhance their binding to the carrying polymer, for example. A length of the fibers can also impact the physical properties of the material into which they are mixed, for example.

[0055] In certain examples, tooling is adjusted to manufacture panels with filler. For example, hollow microspheres can be crushed with the pressure of injection molding, so multiple gates can be used to feed the plastic into the mold while keeping pressure below a threshold to avoid bursting or crushing the spheres. Alternatively or additionally, spheres can be chemically treated to better bond to surrounding plastic to act like a continuous part. Further, a temperature of a mold can be adjusted such that the plastic forms a smoother, nicer surface in the resulting part without the glass spheres showing through. As such, the panel(s) can be lightened while maintaining structural integrity as well as surface appearance.

[0056] Thus, a monolithic part can be formed, and, in certain examples, multiple monocoque parts can be formed and connected as the body of an ambulation aid. In certain examples, the part is of uniform density. In other examples, density of the part varies throughout as stiffeners, reinforcements, attachment points, etc., increase the density of the foam/other airinfused material part at various locations. Inserts, attachment points, etc., can be injection molded and then inserted into the steam chest mold to be integrated into the steam chest molded foam/other air-infused material body of the ambulation aid, for example. As such, the steam-chest molded foam/other air-infused material can be lightweight, strong, durable, semi-rigid, etc., while plastic insert(s) are rigid, rubber insert(s) are flexible, etc. Inserts, additives, etc., introduce different material property(-ies) than the foam or other air-infused material provides.

[0057] In other examples, engineered particle foam is used to form the ambulation aid body. In other examples, plastic can be foamed, expanded, or otherwise infused with air to form a structural foam using injection-molded plastic with integrated bubbles formed in the plastic by injecting air to create air bubbles in the plastic (e.g., a chemical foaming agent added to a resin to form an air-infused material, etc.). In some examples, plastic can be inserted/injected without air infusion. In other examples, gas-assist injection molding can be used to inject air to create bubbles or hollowed spaces in an injection-molded part. In some examples, an expanding foam, such as a polyurethane rigid foam, can be used. A chemical foaming agent can create carbon dioxide bubbles in a polymer, for example. In some examples, a block of foam and/or other air-infused material can be molded, and a computer numerical control (CNC) machine can be used to cut out one or more panels forming an ambulation aid. In some examples, all or part of the ambulation aid can be formed using additive manufacturing.

[0058] In certain examples, plastic used to form all or part of the ambulation aid (e.g., the upper frame, the lower frame, components/accessories, etc.) can be formed with hollow glass microspheres embedded in injection-molded parts to reduce weight, making the formed portions easier to transport for mobility-impaired users, etc. Using of microspheres also reduces shrinking and warpage of the molded parts, making the parts function and look better. Alternatively or additionally, chemical foaming agents, physical foaming injection, etc., can be applied to form all or part of the ambulation aid (e.g., upper portion, lower portion, components/accessories, etc.) as described above.

[0059] Certain examples described and disclosed herein relate to ambulation aids, and more specifically to ambulation aids formed in unibody, unitary, monocoque, and/or semi- monocoque construction for simplified manufacture, durable construction, and user support, as well as more pleasing aesthetics and increased design options. For example, an ambulation aid can be constructed of foam, molded polymer material, other air-infused material, etc., allowing for a lightweight, yet strong, customizable, and economically viable solution. The inventive structure also allows for integrated accommodations such as personal storage, seating, height adjustment, walking cane storage, cup holder, tray, headlight, and/or the like to be integrated into and/or otherwise attached to the structure.

[0060] In certain examples, an ambulation aid apparatus is formed to unify a plurality of structural and/or ornamental features into a single integral part. For example, a body of the example ambulation aid apparatus may be formed of foam or other air-infused material to provide a support frame for the user while also enabling accessories to be provided as part of the ambulation aid. Thus, the ambulation aid body provides structural strength and support while also providing a cosmetic exterior and/or interior for the apparatus in a single integral part (e.g., using steam-chest molding, etc.). The body of the example ambulation aid may also provide integrated mounting and/or attachment point(s) to attach one or more components/ subassemblies to the body. For example, one or more aesthetic and/or functional accessories can be attached to one or more surfaces of the part. Such attachment can be permanent, removable, or replaceable. For example, one or more color panels, hooks, lights, body sensors (e.g., electrocardiogram monitor, other biometric sensor, fall detector, global positioning sensor (GPS), etc.), proximity sensor, other alarm, reflectors, oxygen tubes, oxygen tank mounts, batteries, latches, etc., can be (removably) attached to the integral ambulation aid part.

[0061] In certain examples, the bottom portion can operate as an ambulation aid without the top portion. For example, a rigid, monocoque bottom frame can be used with handle(s) and wheel(s)/skid(s) to function as a walker/ambulation aid. As such, the lower or bottom portion is a monocoque frame to support the weight of a user and to guide and/or otherwise assist the mobility of the user. The bottom portion can be useful for support and mobility without other attachment. However, an upper portion can optionally be affixed to the lower/bottom portion with additional items for cushioning/absorption of impact, storage, seating, tray, etc. Such an upper portion can be referred to as a convenience module. As such, when positioned on the lower portion, the convenience module provides additional functionality apart from support and mobility of the user, such as rest, storage, eating, etc.

[0062] Certain examples include two wheels, three wheels, or four wheels with one or more brakes such as rolling and/or parking brakes. Certain examples include front wheel(s) with sliding surfaces in the rear. Certain examples include no wheels, with sliders/skids and/or pads at the wheel locations. In certain examples, covers or “socks” can be placed over the skid/ski/slider(s) to help prevent damage to flooring or other surface over which the ambulation aid/rollator/walker is moved. Certain examples include double wheels in one or more locations for additional stability.

[0063] Certain examples can be provided in various sizes to accommodate different sizes, heights, weights, etc. For example, an ambulation aid can be configured to accommodate a child. An ambulation aid can be configured to accommodate heavier and/or larger users (“bariatric”), for example.

[0064] Certain examples provide an ambulation or mobility aid (often referred to as a “rollator” or “walker”) constructed to allow for a wide range of design and engineering flexibility, while remaining lightweight, strong, and affordable. Certain examples provide a monocoque upper body portion and a monocoque bottom frame or portion (rather than a tubular frame constructed from a plurality of separate but connected tubes and including additional attachments).

[0065] In certain examples, the ambulation aid allows a user to store personal items, sit down when necessary or desired, carry a plate of food or other items on a flat surface, etc. The example ambulation aid adjusts to a user’s height and provides for the storage of a secondary walking aid such as a cane, cup, purse or other bag, etc. The inventive structure also allows for accommodations such as personal storage, seating, height adjustment, walking cane storage, and a tray to be integrated into the structure.

[0066] Certain examples provide an apparatus including an ambulation aid body formed as an integral part (e.g., upper and lower portions integrated together through one or more connections, etc.), the integral part formed to provide support for mobility of a user through the integral part, the integral part providing a plurality of grippable areas to facilitate user movement and support through the integral part. [0067] In some examples, the ambulation aid body is to be formed as an integral part via a steam chest molding process. In some examples, the ambulation aid body is to be formed from a polymer material, such as balls, beads, pellets, and/or other air-infused particles, that can be fused to form the ambulation aid body. In some examples, the apparatus includes a seat to support a user when in use and to allow the user to walk inside a boundary of the ambulation aid body for support and movement via the ambulation aid body at least when the seat is not in use. In some examples, the apparatus includes a tray to support an item when in use and to allow the user to walk inside a boundary of the ambulation aid body for support and movement via the ambulation aid body at least when the tray is not in use.

[0068] In some examples, the plurality of grippable areas include one or more of a handle, an opening, a top of the ambulation aid body, a side of the ambulation aid body, etc. In some examples, the handle is at least one of movably affixed to or incorporated into the ambulation aid body. In some examples, the handle is to be movable with respect to the ambulation aid body to adjust a height of the ambulation aid body with respect to the user.

[0069] In some examples, the apparatus includes at least one of a wheel, a post, or a skid affixed to the ambulation aid body to facilitate movement of the ambulation aid body by the user. In some examples, the ambulation aid body includes one or more connections between sections of the integral body to enable the ambulation aid body to be folded, and wherein, when folded, the ambulation aid body is to remain self-standing and movable. In some examples, the ambulation aid body further includes storage, wherein the storage is to retain an item placed in the storage when the ambulation aid body is folded. In certain examples, power can be provided to the ambulation aid such as via solar cells, battery, induction, connection, etc. (e.g., power can be provided to one or more wheels of the ambulation aid on demand, etc.). [0070] Certain examples provide a method of forming an ambulation aid. The example method includes forming, from a supply of moldable material, an ambulation aid body as an integral part via steam chest molding, for example.

[0071] In some examples, the method further includes attaching one or more subassemblies to the formed ambulation aid body. In some examples, the one or more subassemblies include a seat to support a user when in use and to allow the user to walk inside a boundary of the ambulation aid body for support and movement via the ambulation aid body at least when the seat is not in use. In some examples, the one or more subassemblies include a tray to support an item when in use and to allow the user to walk inside a boundary of the ambulation aid body for support and movement via the ambulation aid body at least when the tray is not in use. In some examples, the one or more subassemblies include at least one of wheels and a skid affixed to the ambulation aid body to facilitate movement of the ambulation aid body by the user. In some examples, the one or more subassemblies include storage (e.g., a storage compartment), wherein the storage is to retain an item placed in the storage when the ambulation aid body is folded.

[0072] Certain examples provide an ambulation aid apparatus. The example ambulation aid apparatus includes a primary panel formed of foam or other air-infused material to provide support for and assist in mobility and stability of a user, the primary panel formed to interrelate with one or more subassemblies to provide an integrated part to assist in providing support for and improved mobility of the user through the integrated part.

[0073] In some examples, the one or more subassemblies include a plurality of secondary foam/air-infused material panels, the plurality of secondary panels movably connected to the primary panel to form a body of the ambulatory aid and arranged to provide support, stability, and mobility to a user when the secondary panels are extended in relation to the primary panel. In some examples, connections between the primary panel and the plurality of secondary panels enable the ambulation aid apparatus to be folded, and wherein, when folded, the ambulation aid apparatus is to remain self-standing and movable.

Example Ambulation Aids

[0074] FIG. 1A illustrates an example hybrid monocoque ambulation aid 100. The example ambulation aid 100 of FIG. 1A includes a top portion 110 (also referred to as an upper portion or a main panel) and a bottom portion 120 (also referred to as a lower portion, a lower panel, or a bottom frame). Each of the top portion 110 and the bottom portion 120 is implemented as a monocoque part. As shown in the example of FIG. 1A, side panels 130 and 135 (not shown in this view but mirrors 130, for example) can engage with or be formed as a part of the bottom portion 120. For example, the side panels 130-135 can be attached via hinges 136-138 (not shown in this view but mirror the hinge 136) to the bottom portion 120 or can forma contiguous piece with the bottom portion 120. The hinges 136-138 can be living hinges, for example. In other examples (not shown), the side panels 130-135 can be attached to the upper portion 110. Each of the panels or portions 110-135 can be formed as an integral part using a manufacturing process such as steam-chest molding, injection molding, additive manufacturing, subtractive manufacturing, etc. The panels or portions 110-135 can be formed of one or more foams, airinfused materials, polymers, etc. In certain examples, materials such as beads, hollow spheres, etc., can be mixed into the foam, polymer, etc., to reduce weight while maintaining, or perhaps improving, structural support of the portion 110-135.

[0075] In certain examples, the lower portion 120 is designed to accommodate the upper portion 110 (e.g., by resting the upper portion 110 on top of the lower portion 120, by nesting the upper portion 110 on top of the lower portion 120, by affixing the upper portion 110 on top of the lower portion 120, by removably latching/clipping/connecting the upper portion 110 onto the lower portion 120, etc.). However, in some such examples, the lower portion 120 can be usable without the upper portion 110 to support the weight and mobility of a user. As such, the upper portion 110 can removably provide accessories and/or other optional elements such as a seat, tray, storage compartment, light, battery power, etc., which can also be referred to collectively as a convenience module. The convenience module 110 can be positioned on and/or otherwise removably attached to the lower frame 120 when desired/needed and removed when not desired/needed, for example. The upper convenience module 110 can be stored separately from the lower frame 120, for example. In some examples, the convenience module 110 can include or be provided with an attachable strap to assist in carrying the convenience module 110 separate from the lower frame 120.

[0076] In certain examples, the lower portion 120 is formed of a rigid material (e.g., injected molded fiberglass/carbon fiber/etc., hydroformed aluminum, welded metal, thermoformed, blow molded, roto molded, etc.), harder than material of the upper portion 110 and designed to support the weight of a user and enable user mobility. The upper portion 110 can then be formed of a shock-absorbing material (e.g., same or similar materials as the lower portion 120, EPP, more flexible injection molded materials, fabric construction with or without a frame, etc.), softer than the material of the lower portion 120 and designed to absorb an impact from the wheels 160-166 contacting irregularities on the ground, normal movement of the user, the user falling or slumping against the upper portion 110, etc. One or both portions 110, 120 can be formed with a strengthener and/or other filler such as fiber, talc, spheres/beads, etc., to provide stiffness and/or strength in a panel, for example. As such, the hybrid ambulation aid 100 provides a dual benefit of support and protection through the interconnected combination of the upper portion 110 and the lower portion 120. In certain examples, the upper portion 110 can be removed when not in use, can be exchanged for another upper portion 110, can be removed for separate use, etc.

[0077] In certain examples, the side panels 130-135 can be formed together with the bottom portion 120 as a solid contiguous unit or as sections joined by lesser material in the form of a living hinge. For example, a living hinge is a thinner, more flexible section of material formed in the same mold and connecting the right panel 130 to the center bottom panel 120 and, similarly, connecting the left panel 135 to the center bottom panel 120 while allowing some movement of the left and right panels 130-135 with respect to the center bottom panel 120.

[0078] The example ambulation aid 100 of FIG. 1A also includes a pair of adjustable handles 140-145. The handles 140-145 include brake levers 150-155 (e.g., a brake mechanism) to control (e.g., via cables, wires, etc.) brakes (not shown in this view) engaged to one or more wheels 160-166 (wheel 166 not shown in this view but mirrors 164, for example). The brake levers 150-155 engage brakes to lock or unlock one or more wheels 160-166 to allow the ambulation aid 100 to move or to stay in position at a location, for example. In certain examples, the brakes slow the wheels 160-166 by squeezing or engaging with the wheels. When the ambulation aid 100 is “parked” or in a sitting configuration with a seat (such as the seat 190, not visible in this view but shown in FIG. IB) in position for a user to sit, the brake levers 150-155 engage to lock the wheels 160-166 to prevent the ambulation aid 100 from rolling (e.g., while sitting, resting on an incline, etc.), for example.

[0079] As shown in the example of FIG. 1A, the ambulation aid 100 can also include a tray 170 (e.g., a foldable tray, a fixed tray, etc.). The example tray 170 can include a cup holder 175 and/or other recession, hook, handle, protrusion, etc. In certain examples, the tray 170 is movable to increase in size and provide additional surface area to a user. For example, the tray 170 folds in place against the center panel 110 for movement, storage, etc., as shown in the example of FIG. 1 A. The tray 170 then folds away from the center panel 110 to provide additional surface area for use (e.g., when the ambulation aid 100 is stationary, etc.). The tray 170 can be movable on a hinge (e.g., a hinge, a piano hinge, a door hinge, a drop pin, a living hinge, etc.), for example. In other examples, the geometry of the tray 170 engages with the center panel 110 to retain the tray 170 and provide a hinge action without a separate hinge. In some examples, the tray 170 can be removed for cleaning, replacement, etc. [0080] In certain examples, the hinges 136-138 (not shown in this view but mirroring the hinge 136) lock the side panels 130-135 in position with respect to the center bottom panel 120. When locked in place, the combination of the center bottom panel 120 and the side panels 130, 135 forms a structure to support the user. The combination of the center bottom panel 120 and side panels 130-135 engages with the upper portion 120 to provide support, stability, and mobility to a user via a modular ambulation aid 100. In certain examples, the lower portion or panel 120 can provide support, stability, and mobility to a user in conjunction with the upper portion 110 without the side panels 130-135. The example ambulation aid 100 can be modular because different top portions 110 can be fit with different bottom portions 120, the bottom portion 120 and/or the top portion 110 can be provided with or without side panels 130-135, etc., to form a hybrid monocoque ambulation aid 100 customized to a user, environment, application, etc. In certain examples, when present and unlocked, the side panels 130, 135 can be folded up against the center bottom panel 120 to compact the ambulation aid 100 for storage, transport (e.g., in a vehicle, container, etc.), etc. In certain examples, the top portion 110 can be separated from the bottom portion 120 for storage, transport, etc. In certain examples, the top portion 110 is removably latched to the bottom portion 120 and can be released by actuating a release button, switch, lever, etc. 180. The upper portion 110 can include a light 185, for example. The light 185 can be solar, powered by a battery (not shown but incorporated into the upper portion 110), rechargeable via external power connection, etc.

[0081] FIG. IB shows another view of the example hybrid monocoque ambulation aid 100. The example of FIG. IB shows another view of the upper portion 110, lower portion 120, side panels 130-135, handles 140-145, brake levers 150-155, wheels 160-166, etc. The example tray 170 and cup holder 175 in the tray 170 are also shown. The latch release 180 to disengage the upper portion 110 from the lower portion 120 is also shown. The upper portion 110 can include the light 185, for example. As shown in the example of FIG. IB, the ambulation aid 100 also optionally includes a seat 190 and a storage compartment accessible through a storage door 195. As shown in the example of FIG. IB, the seat 190 can be deployed with respect to the side panels 130-135 (e.g., moved down to rest against the side panels 130-135, stretched or otherwise expanded between the side panels 130-135 within an ambit of the lower frame 120, etc.). Additionally, as shown in the example of FIG. IB, the lower frame 120 (e.g., more specifically, the side panels 130-135 of the lower frame 120) can include curb climb assist features 168-169 to aid a user in changing elevation with the ambulation aid 100 over a curb or other increase in elevation.

[0082] In certain examples, a depth of the front or top panel 110 is sized to reduce “reach over” when used in position next to a countertop, a sink, etc., over which a user may desire to reach while having the ambulation aid 100 available for support. At the same time the depth provides sufficient depth for storage in the upper portion 110 in implementations providing such storage (e.g., for a portable oxygen tank, oxygen concentrator, battery, etc.). The depth of the upper portion 110 also affects a size of the integrated tray, in implementations providing the tray. For example, the tray, when folded out, can accommodate a full size dinner plate. In certain examples, the side panels 130-135 are sized for compactness when the ambulation aid is folded. Additionally, a wheel base (e.g., distance from front wheels 160, 162 to back wheels 164, 166) is set for stability (e.g., a longer wheel base creates more stability in the ambulation aid 100), for example. A wider wheel track also increases stability, but is limited by a width of standard household doors, for example. In certain examples, a distance from the handles 140-145 to the front wheels 160-162 affects an ability of the walker 100 to roll smoothly over obstacles. As such, a tradeoff can be made between smooth motion and an ability for a user to walk upright and inside an ambit of the walker 100 in many or most circumstances, for example.

[0083] FIG. 2 shows the bottom or lower portion or frame 120 without the upper portion

110. In such an implementation, the upper portion 110 forms a convenience module that can be removed, sold separately, not included, etc. The lower frame 120 supports a user through supports 210-215 (also shown in FIGS. 1A-1B) forming part of the lower frame 120 on which the handles 140-145 and brake levers 150-155 are attached. As shown in the example of FIG. 2 (also shown in FIGS. 1A-1B), the bottom portion 120 can include one or more hinges 136-138 (e.g., frame hinge, living hinge, etc.) to allow the bottom portion 120 to be folded or otherwise collapsed. As shown in the example of FIG. 2, the hinges 136 and 138 are aligned such that the bottom portion 120 can be folded for storage, transportation, etc. If the upper portion 110 (e.g., the convenience module) is present, the upper portion 110 can be affixed to the lower portion 120, and the hinges 136-138 enable the sides 130-135 to fold with respect to the center of the lower portion 120 as well as the upper portion 110 to enable compact storage.

[0084] As shown in the example of FIG. 2, the ambulation aid 100 can further include a locking frame hinge release mechanism 230-235 to release the hinges 136-138 which can lock in place when moved into the “open” position (e.g., to open the ambulation aid 100 for use). The ambulation aid 100 can also include one or more handles 240-245 to enable ease of carrying the ambulation aid 100 when the ambulation aid 100 is in a “closed” or folded position, for example.

[0085] FIG. 3 illustrates an alternate implementation of the hybrid monocoque ambulation aid 100. As shown in the example of FIG. 3, the top portion 110 is a first part (e.g., a monocoque part, a thin molded “box”, a unibody part, fabric, soft material, etc.) and the bottom portion 120 is a second part (e.g., a second monocoque part, unibody part, molded part, etc.). The top portion 110 fits with respect to the bottom portion 120 to provide accessories, such as a tray, seat, storage, etc., to a user. The top portion 110 can also be formed of a softer material to provide shock absorption and/or cushion to a user in an event of an impact, a fall, etc. Handles 140-145 are provided without brakes, and wheels 160-166 are affixed to the bottom portion 120. The bottom portion 120 includes hinges 136-138 (e.g., living hinges, mechanical hinges, etc.) to allow the bottom portion 120 to flex or fold. The example aid 100 of FIG. 3 may or may not include side panels 130-135. As shown in the example of FIG. 3, additional side panels 310-315 (not visible in this view but mirroring the side panel ) can be positioned with respect to the bottom portion 120 to provide additional support (e.g., for a tray, seat, user, etc.). In certain examples, the side panels 310-315 can be removable color panels for accent/decoration as well as support, etc.

[0086] In certain examples, as described above, some or all of the elements of the example ambulation aid 100 can be formed of foam, air-infused material, polymer, fiberglass, carbon fiber, metal, etc., using a process such as steam-chest molding, injection molding, blow molding, welding, hydroforming, stamping, thermoforming, additive manufacturing, subtractive manufacturing, etc. In certain examples, attachment points or inserts, such as for wheel attachments, handle attachments, hinges, brakes, reinforcement, etc., can be provided as inserts formed in one or more of the panels 110-135. As such, inserts to strengthen one or more of the panels 110-135, and/or attachment points to connect attachments such as handle 140-145, wheel 160-166, etc., can be formed into the panels 110-135 of the apparatus 100.

[0087] Thus, one or more monolithic parts can be formed as the body of the ambulation aid 100. In certain examples, the parts are of uniform density. In other example, density of the part(s) varies throughout as stiffeners, reinforcements, attachment points, etc., increase the density of the part at various locations. Inserts, attachment points, etc., can be injected molded and then inserted into the steam chest mold to be integrated into the steam chest molded body of the ambulation aid, for example. As such, the material used to form the top portion 110, the bottom portion 120, and/or the side panels 130-135 can be lightweight, strong, durable, semi-rigid, etc., while plastic insert(s) are rigid, rubber insert(s) are flexible, etc. Inserts, additives, etc., introduce different material property(-ies) than the material provides, for example. In certain examples, metal and/or other bracing can be used in conjunction with any of the forming processes described above to reinforce a part. For example, metal braces (e.g., four metal braces, etc.) can be used in a corner (e.g., front comer(s), etc.) of an injection molded front panel to provide additional support.

[0088] FIGS. 4-13 illustrate additional views of the ambulation aid implementation of FIGS. 1 A-2. For example, FIG. 4 shows a front view of the example rollator/walker/ambulation aid 100. FIG. 5 shows a rear view of the example ambulation aid 100. FIGS. 6-7 illustrate example side views of the ambulation aid 100. FIG. 8 shows a top view of the example ambulation aid 100, and FIG. 9 shows an example bottom view. FIGS. 10-13 depict additional example views of the ambulation aid 100.

[0089] As shown in FIGS. 4-13, for example, one or more points of the example ambulation aid can have multiple wheels (e.g., double-wheeled, etc.). As shown in FIGS. 4-13, handles can extend between, rather than through, the top portion and/or side panels. In certain examples, the handles can be removable for storage, transportation, etc., such as when the bottom frame is folded (e.g., at the hinges).

[0090] FIG. 14 illustrates the example ambulation aid 100 folded or collapsed 1410 for storage, transport, etc. (e.g., in a box for shipping, display/storage on a shelf, etc.). In certain examples, the side panels 130-135 can be removed, the bottom frame 120 can be folded, the handles 140-145 can be removed, etc., for ease of shipping to then be assembled by a user. A top portion or front panel can also be removed for shipping, travel, storage, etc., for example. In one example, the ambulation aid 100 can fit in a box that is 23 inches long, 10 inches wide, and 21 inches tall, or 23 inches long by 11 inches wide by 23 inches tall, etc. In certain examples, side panels can remain attached to the frame but folded in. Then, for assembly, handles are inserted and, potentially, the convenience module is attached. The ambulation aid is then ready for use.

[0091] FIGS. 15-16 show views of a design alternative without side panels. As shown in these examples, the ambulation aid can be formed of the base or bottom frame and the upper or top portion. As shown in FIG. 16, the ambulation aid can be formed without handles and/or with removable handles. As shown in FIGS. 15-16, the ambulation aid can be movable on wheels. [0092] FIGS. 17-25 illustrate various views of the base or bottom frame 120. In certain examples, the ambulation aid can be formed of the bottom frame 120, such as with handles, without a top portion. As described above, the top portion 110 can be implemented as a convenience module to separately provide the seat 190, storage compartment 195, tray 170, etc. The bottom frame 120 can then be used with or without the convenience module 110.

[0093] FIGS. 26-28 depict exploded views of the parts of the ambulation aid apparatus 100. As shown in the example of FIGS. 26-28, the parts of the ambulation aid apparatus 100 can be manufactured separately and provided for assembly. In certain examples, once assembled, the components of the ambulation aid remain conjoined. In other examples, one or more components can be removed for ease of storage, transport, shipping, replacement, maintenance, etc.

[0094] FIGS. 29-37 show examples of the hybrid ambulation aid in a collapsed or folded state/mode/condition. As shown in the example of FIGS. 29-37, the ambulation aid apparatus can be folded at hinges in the bottom frame with the side panels separated from the top portion. Wheels and handles can remain intact, and the ambulation aid can remain positionable upright while in its folded mode/state/configuration.
