This application is a continuation of U.S. application Ser. No. 18/191,584, filed Mar. 28, 2023 which is a continuation-in-part of U.S. application Ser. No. 16/640,674, filed Aug. 22, 2018, now U.S. Pat. No. 11,612,782 which issued on Mar. 28, 2023, which is a 371 application of PCT Application No. PCT/US2018/047601, filed on Aug. 22, 2018, which claims priority to U.S. Provisional Application No. 62/548,523, filed Aug. 22, 2017, and U.S. Provisional Application No, 62/554,671, filed Sep. 6, 2017, each of which is hereby incorporated by reference herein in its entirety.

The present invention relates to exercise apparatus, and, more specifically, to exercise apparatus comprising a mobility mat and attachable orthopedic device.

The fitness industry has grown significantly as society increasingly recognizes the relationship between health and fitness. In order to stay healthy, people need a pain free way to exercise. Freestyle fitness equipment has grown in popularity as consumers desire exercise equipment that can be easily transported, used in locations other than a gym, and used without an instructor. However, existing exercise apparatus can be outdated, expensive, and with limited or ineffective applications.

For example, existing yoga mats provide a basic structure upon which to perform free-standing exercises. However, existing yoga mats generally lack any assistive features that can help a user perform progressive chains of movement to match natural positions, The lack of additional features of existing yoga mats limits a user's exercise routine to unassisted movement. A user is more likely to be injured during unassisted movements due to instability and improper joint and muscle load as the user struggles to maintain proper balance. A user's knees and ankles are particularly at risk.

Furthermore, a user can risk additional injury if the user attempts to supplement the unassisted movements with heavy metal weights. Heavy metal weights do not allow variety of force for the appropriate joint and soft tissue group. This risks additional injury because the user may not even be able to determine the appropriate force. Additionally, unassisted movements do not enable progressive, controlled positions for targeted tissue recovery through chains of movement.

Assistive features can help users explore a wider range of movements, achieve greater versatility in limb positions, rehabilitate injured joints and/or muscles, target specific body parts, combinations thereof, or the like.

Therefore, it would be desirable to have freestyle fitness equipment that can address the deficiencies described above and/or meet the fitness and rehabilitative needs of consumers.

The first and second connectorsare configured to mate with one another such that the orthopedic devicemay be coupled to the mobility mat. It is contemplated that any suitable type of connectersmay be used including, for example, hooks, snaps, hook-and-loop type fasteners, Velcro, male and female connectors, adhesive elements, magnets, or any other material, any combination thereof or the like.

The orthopedic devicewill be discussed further with respect to. Example exercise techniques involving both orthopedic deviceand mobility matwill be discussed later with respect to.

In the non-limiting embodiment of, the mobility matincludes four segments: a top segmenta second segmenta third segmentand a bottom segmentAlthough four segmentsare shown in, any suitable number of segmentscan be included-e.g., a one-piece design, as illustrated in the embodiment of. The four segmentsandshown inare generally rectangular in shape and can provide a cumulative length approximately equal to the average height of a person. For example, the four segmentsandcan have a cumulative length of 74 inches. Each segment can have a width of 30.5 inches and a depth of approximately one inch. Although the four segmentsandare shown into be approximately uniform in length, each segment can have a unique length. For example, the top and bottom segmentscan have a length of 17.75 inches while second and third segmentshave a length of 19.25 inches. In some embodiments, the widths of each segment are generally the same. In general, the rectangular shape and size of the plurality of segmentsandcan enable a variety of exercise positions along the length and width of the mat. The plurality of segmentsandcan provide cushioning to a user's head, torso, and limbs as the user moves through desired exercise positions.

In accordance with an embodiment of the present invention, the mobility matcan be made of a plurality of layers or a single layer such that the body of the matprovides cushioning between a user and the floor. In this regard, the body of the mobility mat, including segments thereof, when provided, can be a compliant and/or pliant foam material. Referring to the embodiment of, it is contemplated that each of the four segments,may be made of the same or different materials or combinations of materials. For example, segmentsandcan be constructed of foam, rubber, yoga mat material, Naugahyde, leather, vinyl, any other protective material, and any combinations thereof or similar materials.

The top and second segmentand the third and bottom segmentscan be coupled to each other via connecting segmentsThe second and third segmentsandcan be coupled to each other via a generally central connecting segment. Connecting segmentscan be comprised of a material that is generally thinner than the segmentsandConnecting segments,andcan be generally flat, thin, and flexible. In some embodiments, the connecting segmentshave a length Lgenerally equal to a depth D(see) of one of the segmentsorIn some embodiments, the generally central connecting sectionhas a length Lthat is generally twice as long as the length Lof the connecting segmentsSuch measurements assist the mobility matto fold neatly so that the four segmentsandlie generally flush against one another when the mobility matis in a folded position. This is discussed further with respect to.

Referring back to, the mobility matscan have one or more foot holdsand hand holds. Although the foot holdsand hand holdsare referred to herein to indicate the use of a particular limb, both sets of holds,can be used by any limb of the user, i.e., the user may use the foot and hand holds,interchangeably, depending, for example, on the type of exercise, position, or stretch that is being performed. For example, a user can grasp the foot holdwith his or her hand or anchor his or her foot between the hand holdand the top surfaceof the mobility mat.

As shown in, each segmentandcan include at least one hand hold. In a particular configuration of the present disclosure, each segmentandincludes two hand holds, wherein each hand hold is positioned on an opposing side of the respective segment at or near the edge of the mobility mat. Additionally, the bottom segmentas shown in FIG. I can include the one or more (e.g., two) foot holds. The opposing ends of the foot holdsand hand holdsare generally coupled to the top surfaceof the mobility mat, thereby forming an aperture between the respective foot/hand hold,and the top surfaceof the mobility matsuch that a human hand or foot may be received by the aperture. The foot holdsand/or hand holdsthereby assist in anchoring the user to the mobility matsuch that the user can position his or her body in various exercise positions on the mobility mat. Additionally, the sets of consecutive hand holdsalong the sides of-mobility matallow a user to move through various hand holdsto encourage progressive physical movement at different angles. This can be especially beneficial for therapeutic and orthotic recoveries. Particular shapes of hand holdsand foot holdsare discussed in more detail below with respect to.

In the embodiment of, the hand holdsare positioned at varying distances from the edgeof the mobility mat. For example, the hand holdson the top and bottom segmentsare farther inset into an interior portion of the mobility matthan the hand holdson the second and third segmentsof the mobility mat. For example, the hand holdscan vary from between 0.5-4 inches from the edgeof the mobility mat. Such a configuration allows the respective hand holdsto lie adjacent to each other, without overlapping, when the mobility matis in a folded position such that a compact, generally slim folded position may be obtained.

The mobility matcan further include handlespositioned at generally opposite ends,thereof. The handlesmay be positioned along the opposing edges, near the opposing edgeson a back side of the mobility mat, or the like (discussed further with respect to), The handlescan be used to easily move mobility matwhen mobility matis stretched out on a surface or to carry the mobility matwhen it is in a folded position (see).

In the illustrated embodiments, the mobility matadditionally includes a cushion. The cushioncan provide additional padding fix a user when the user exercises on the mobility mat. For example, the cushioncan be positioned on the top segmentso that the cushionmay be adjacent to the orthopedic device. The cushioncan provide additional padding as a seat when the user interacts with the orthopedic device. In some examples, the cushioncan provide padding for a user's shin, a user's forearm, or a user's head and neck during various exercises. In some examples, cushioncan be removably attached (using, e.g., hook-and-loop type fasteners or any suitable attaching feature or combination of attaching features) from mobility mat. Removably attaching the cushionmay be desirable for ease of laundering or replacement. The cushionfeatures are discussed in more detail below with respect to.

Referring back to, the mobility matmay also include a receiving element. Although receiving elementofis coupled to the bottom segment, the receiving elementcan be located in any of the plurality of segments, andThe receiving elementcan be configured to receive a supplemental exercise device such as an exercise band, resistance band, or any other standalone exercise element. Receiving element is discussed further with respect to.

Referring back to, the mobility matcan additionally include a counterbalancing weight (not pictured) in locationandThe counterbalancing weight can serve to provide extra weight to the mobility matsuch that ends of the mobility mat, andare not pulled up or shifted when a user is performing pushups or sit ups.

Although the figures of the present application show a particular configuration of the assistive features of an exemplary mobility mat, a person skilled in the art would understand that an exemplary mobility mat, according to embodiments of the present disclosure, can have more or less assistive features. For example, although the mobility matofincludes eight hand holdsand two foot holds, there can be more or less of either the hand holdsor foot holds. Additionally, the assistive features can have different arrangements than as shown in the present disclosure, so long as the assistive features are configured to be engaged by a user.

shows a bottom sideof an exemplary mobility mat, according to an embodiment of the present disclosure. The mobility matofincludes similar elements with same numbering and functions as the elements of. Additionally,shows first coupling elements, bottom handles, and second coupling elements. The first coupling elementsand the second coupling elementsare configured to mate with one another such that each of the first coupling elementscan couple with a respective one of the second coupling elementswhen in contact therewith. For example, coupling elementsandcan be hooks, snaps, hook-and-loop type fasteners, Velcro®, male and female connectors, adhesive elements, magnets, or any other material, any combination thereof or the like, or element (or combinations thereof) that generally securely fastens. Coupling elementsandcan connect with each other when mobility mat is in a folded position in order to assist in securing the mobility matin folded position (see). Additionally, the bottom handlesas generally positioned can be used to carry mobility matwhen mobility matis in a folded position.

shows a side view of an exemplary mobility mat, according to an embodiment of the present disclosure.includes similar elements with the same numbering and same functions as elements of.shows how specific assistive features extend away from the top surfaceof the mobility mat, thereby forming an aperturebetween the assistive feature(s) and the top surfaceof the mobility mat. For example, hand holdsand foot holdscan be configured to extend away from mobility mat. The apertureformed therebetween is useful in providing fix easy anchoring of a body limb by a user during an exercise routine.

show various perspective views of the exemplary cushion, according to one non-limiting embodiment of the present disclosure. The cushionmay include a base, a first extensiona second extensiona first portiona second portionand connector portions. The cushioncan be formed of any suitable material. It may be desirable for the cushionto be formed of a compressible material(s) designed to cushion a user's weight. In one embodiment, the cushionis formed of a foam or foam-like material having a cover thereon (not pictured). The cover can assist in preventing blisters when a user's skin repeatedly contacts the cushionduring exercise. Additionally, the cover can assist in wicking away a user's sweat. In some instances, the cover can be removable for ease of laundering, replacement, or interchangeability. As briefly discussed above, the cushionitself can also be removeable from the mobility mat.

In one non-limiting embodiment, the cushionis shaped in a hollowed semi-circular shape with a base, a first extensionextending from a first side of the baseand a second extensionextending from the second side of the base. In some embodiments, each extensionandincludes an end portionandand connector portions. The end portionsandcan be wider than connector portionsbridging each respective end portionandand the base. Although an exemplary shape of the cushionis shown in, it is contemplated that any shape can be used so long as the cushion is configured to fit within the bottom segmentof the mobility mat. For example, the cushioncan be rectangular or circular in nature. The extensionsandlikewise can be of any suitable dimensions. For example, the extensionsandcan be similar to the length of a forearm of a user, or a length of the top segmentof the mobility mat. Similarly, the basecan be configured to extend substantially across the top segmentsuch that the first extensionextends generally parallel with a first edgeof the top segmentand the second extensionextends generally parallel with a second edgeof the top segment

In some examples, the first extensionand the second extensioncan be in a teardrop shape where the end portionsandare wider than the connector portions.

further demonstrates one embodiment in which the cushionhas a contoured design to reduce stress on particular body parts. For example, a main portion of basecan have thicker padding than the connector portions. End portions of first extensionand second extensioncan have thicker padding than non-central portions of first and second extensionand

The cushioncan provide padding to a user during exercises. For example, a user can place his forearm along the first extensionduring a side plank. Thicker padding along the baseand the teardrop end portionassists in allowing the user to reduce stress on his or her write and/or elbow during the exercise. In other examples, the cushioncan be used as a seat or as padding while kneeling. In other examples, the area between the extensionsandcan be a cutout for a pelvic positioning. Therefore, the shape and padding of the cushioncan provide contouring which matches the human form and provides protection of a user's bones, joints, and limbs.

shows a side view of an exemplary pair of foot holds, according to an embodiment of the present disclosure.shows the foot holds, the receiving element, and the cushion.demonstrates how the foot holdscan be configured to extend away from the top surfaceof the bottom segmentof the mobility mat, at, e.g., a similar height to the padding of the cushion. Extending away from the mobility matat such a height assists in allowing the mobility matto neatly fold up with the segments being generally flush with one another when the mobility matis configured in a folded position (see). Opposing ends of the foot holdsmay be coupled to and extend from the mobility matsuch that the foot holdsare curved or in a convex shape, forming an aperturebetween each of the foot holdsand the mobility mat. The aperturesare generally shaped to receive an insertion of a user's foot. Such aperturemay receive a user's foot during exercise routines, for example.

Additionally, foot holdscan include a removeable cover (not shown) which provides additional padding. This removeable cover can prevent blistering or skin abrasions of a user's feet while anchoring to the foot holds.

additionally shows a schematic representation of the receiving element. The receiving elementcan be, for example, a j-hook, an s-hook, a clamp hook, a carabineer, or any other receiving element configured to optionally receive or be coupled with additional exercise equipment. For example, the additional exercise equipment can be an elastic exercise device or other resistance tool. In some examples, the receiving elementcan have an overlay of fabric or padding (not shown) to cover the receiving elementwhen not in use by the user. Such an overlay may assist in preventing injury to the user from unintentional contact with the receiving element.

shows a side view of an exemplary hand holdon any segmentof the mobility mat, according to an embodiment of the present disclosure. The hand holdcan include a first end portion, a middle portion, a second end portion, and optional grips, A user can grasp the hand holdduring exercise routines while using the mobility mat, according to an embodiment of the present disclosure. Each portion,, andhas a unique angle from the user and can therefore exercise different aspects of the user's grip. Additionally, a user can progressively move through grasping each different portion,, andwhile exercising. For example, a user can grasp the first end portion, then the middle portion, and finally the second end positionduring exercise. The three positions allow a user to gradually advance a hand stretch based on where the user places his or her hand. For example, when grasping first end portion, the user's hand can have an initial position where the hand soft tissues begin to relax, stretch, and elongate. When the hand soft tissues are sufficiently relaxed, the user can advance to middle portionto increase the stretch. Finally, the user can advance to second end portionto achieve a maximum stretch. Therefore, a hand hold, according to an embodiment of the present disclosure, can provide a progression of position choices.

The gripscan be structured to receive a user's fingers. These gripscan help the user have a more secure and/or comfortable grip on the hand hold.

shows an exploded view of a systemincluding components of an exemplary mobility mat, according to an embodiment of the present disclosure. Systemcan include a handle finishing cap, one or more screws, a hand hold, a first layer, an anchor, one or more nuts, a second layer, a third layer, a binding post, one or more binding screws, and a honeycomb structure.

In the illustrated embodiment, the systemincludes a plurality of layers, such as first layer, second layer, and third layer. Although three layers are shown in, it is contemplated that more or fewer layers can be used so long as the at least one layer is thick enough to provide a desired amount of cushioning for a user. The hand holds(and foot holds, not shown in) can be attached to the mobility mat via a handle, the screws, an anchorand nuts. The screwscan attach the hand holdsto the first layer. A handle finishing capcan be placed on top of the screws. The handle finishing capcan protect a user from touching screws. The screwscan extend through the first layerand receive a corresponding nutand anchor. The anchormay assist in anchoring the screwsand in reducing stress on first layerresulting from the screws. The nutsmay also assist in keeping the screwsin place. The hand holds, foot holds, and other supplemental exercise devices, could also be attached to the mobility mat using holding tabs inserted into grommets or apertures formed in the mat body, such as the holding tabs illustrated in.

In the embodiment illustrated in, an exemplary first layercan be a rubber yoga mat or any other padding element. The second layercan be a honeycomb rubber mat, for example with a honeycomb structurewithin the second layer. Such a honeycomb structurecan assist in reducing the weight of the mobility matwhile still providing adequate stability and support. Additionally, the honeycomb structurescan receive the handlessuch that the handlessecurely attach to and weave through honeycomb structures. Weaving through the honeycomb structuresallows the handlesto securely anchor to the second layer. In some embodiments, the second layercan further include adhesive layer on one or both surfaces of to securely couple the first layerto the second layerand the second layerto the third layer. The third layercan include a finishing surface such as, for example, corrugated plastic.

In an alternate embodiment of the present invention, the mobility mat (e.g., mat′) can be constructed from a compliant and pliant foam materials, and moreover can be a single piece construction, such as illustrated in the embodiment shown in.

also shows binding postswith binding screws. Binding postsserve to provide additional stability for the mobility matin ensuring that the plurality of layers,,stay attached. Although only one binding postis pictured in, it is contemplated that binding postscan be positioned at, e.g., edges of each segment of the mobility mat to further securely attach the various layers of the mobility mat. For example, a mobility mat can have about twenty binding postsdistributed throughout the edges of the layers of an exemplary mobility mat. Binding posts can have binding screwswithin the binding postto retain a position of the binding post.

Although an exemplary, non-limiting layering configuration is shown in, additional layering configurations are contemplated by the present disclosure. For example, foot holdsand hand holdscan be attached to any layer in the plurality of layers. The second layeris not limited to a honeycomb configuration. In general, the plurality of layers can include a top cushion layer, an internal structural layer, and an inferior layer to anchor foot holdsand hand holdsand provide a protective covering for the internal structural layer. For example, the inferior layer can be made from. a Naugahyde material, a fabric coated with rubber or vinyl resin, or any combinations thereof or similar materials. Such a layering configuration provides structural support and padding for a user and protection and secure attachments for the assistive features.

illustrate an exemplary mobility mat being folded into a folded position, according to an embodiment of the present disclosure.show an exemplary systemwith similarly numbered elements and corresponding functions to the elements of. For example, in, the top and bottom segmentsandcan be folded so that top surfacesof segmentsandface top surfacesof the second and third segmentsandThis folding can happen along respective connecting sections elementsand(see), as described in more detail below.shows a second folding step can occur alongsuch that bottom surfacesof segmentsandface each other.

illustrates the mobility matin a generally folded position.demonstrates how the second and third segmentsandhave been folded such that bottom surfacesof the top and bottom segmentsandface and are generally flush with each other. This folding can be achieved due to the dimensions of the connecting segment(see). Namely, the connecting segmenthas length Lgenerally equal to about twice the depth Dof a segment.further demonstrates that the assistive features of the mobility matsuch as the hand holdsand the cushioncan be configured to fit neatly against each other while mobility matis in a folded configuration. Put another way, the assistive features do not interfere with one another, e.g., the tops of the assistive features do not contact one another, thereby reducing the bulk of the mobility mat. Additionally, when in the folded position of, the handlespositioned on the bottom surfaceof the mobility matare arranged such that a user can carry the mobility matvia the handles.

further show the first coupling elementsand second coupling elements. The coupling elementsandcan be configured to receive one another and secure mobility matin the folded position. For example, first coupling elementcan be a female connector and second coupling elementcan be a male connector. Second coupling elementcan reach around segmentsandto connect with first coupling elementwhen the mobility matis in the folded position.

An alternate embodiment of a mobility mat for use in an exercise system′ in accordance with the present invention is illustrated inand generally designated as reference numeral. Referring to, the mobility matgenerally comprises a single-piece foam bodyincluding a top surface and a bottom surface and defining a first end portionand a second end portionwith an intermediate portiondisposed therebetween. As with other embodiments described herein, the exercise system′ comprises mobility mat, cushion, and the orthopedic device, as shown in. Additionally, as with other embodiments of mobility mats, a variety of supplemental exercise features can be attached to the mobility mat for exercise purposes. The foam bodyis adapted to be folded about a central axis associated with the intermediate portion, or in the alternative rolled up, when not in use. The mobility matin its folded condition is illustrated in. As so folded, the cushionand supplemental exercise features can be enclosed and held inside the mobility mat.

Referring to, the foam bodyof the mobility matfurther comprises a plurality of grommetsadapted for securely receiving supplemental exercise features, such as foot holdsand hand holds, as described herein, as well as a variety of grip devices, such as ball gripsand handle grips, and resistance bandsand exercise bands. An advantage of the grommets, is that the accessories can be positioned in multiple places on the mat bodyin accordance with the user's desires and needs. For example, the cushioncan be attached to the mobility matat the first end portionthereof. The attachment prevents the cushionfrom sliding during exercise. As shown in, a series of grommetsis provided so that the position of the cushion can be adjusted, perhaps to accommodate the user's size or to conform to a particular exercise or stretching routine.
