DETAILED DESCRIPTION

It will be readily understood that the components of the embodiments as generally described herein and illustrated in the appended figures could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of various embodiments, as represented in the figures, is not intended to limit the scope of the present disclosure, but is merely representative of various embodiments. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by this detailed description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.

Reference throughout this specification to features, advantages, or similar language does not imply that all of the features and advantages that may be realized with the present invention should be or are in any single embodiment of the invention. Rather, language referring to the features and advantages is understood to mean that a specific feature, advantage, or characteristic described in connection with an embodiment is included in at least one embodiment of the present invention. Thus, discussions of the features and advantages, and similar language, throughout this specification may, but do not necessarily, refer to the same embodiment.

Furthermore, the described features, advantages, and characteristics of the invention may be combined in any suitable manner in one or more embodiments. One skilled in the relevant art will recognize, in light of the description herein, that the invention can be practiced without one or more of the specific features or advantages of a particular embodiment. In other instances, additional features and advantages may be recognized in certain embodiments that may not be present in all embodiments of the invention.

Reference throughout this specification to “one embodiment,” “an embodiment,” or similar language means that a particular feature, structure, or characteristic described in connection with the indicated embodiment is included in at least one embodiment of the present invention. Thus, the phrases “in one embodiment,” “in an embodiment,” and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment.

Although many embodiments are described herein, at least some of the embodiments are designated as “air straps” in reference to the ability of a user to perform workout exercises and movements while his or her body is fully suspended off the ground. The types of exercises and movement that might be performed are virtually endless, including cardio exercises, strength training exercises, core exercises, stretching, running, and so forth. Some embodiments allow for a compact fitness device that can be used in commercial gyms or households and allow a comprehensive workout without requiring much space.

In some embodiments, when a user is suspended using an air straps fitness device, the user's entire body is balancing and re-balancing itself over the duration of the exercise or workout. This engages most or all of the user's muscle groups for a comprehensive workout. While the results of such workouts may vary, typical functions include, but are not limited to working glutes for a fit sculpted look, working core for the flattest stomach, shaping legs, toning quads, slimming hips, toning arms, define the back, sculpting the chest, developing bigger shoulders and biceps. Other muscular and/or cardiovascular results can also be achieved.

Multiple studies show continuous resistance exercise programs combining cardio and strength training can deliver dramatically better results. By elevating the heart rate through cardiovascular exercise, a user's strength training becomes much more effective. This allows results to be achieved in a shorter amount of time. Just like playing sports, using multiple muscles at the same time can result in faster physical effects. In some embodiments, a user balances and rebalances on the air straps fitness device, while the user's entire body is engaged in a more natural motion so the user can sculpt a body which will have a more natural look. Additionally, running and other similar exercise motion using “air straps” allow for a low-impact on joints. Various advantages of embodiments may include exercising while engaging core muscles because no torso support member is present to support the torso of a user.

Various configurations of the straps can be implemented. In general, each embodiment of the “air straps” fitness device includes at least three hand/foot holds, at least three lead straps, each one attaching to a corresponding hand/foot hold, and at least one attachment structure, each one to attach one or more straps to a mounting support structure.

FIG. 1 depicts one embodiment of a fitness system 100 for fully suspending a user in the air to exercise including a mounting support structure 102. Although the illustrated fitness system 100 is shown and described with certain components and functionality, other embodiments of the fitness system 100 may include fewer or more components to implement less or more functionality. The illustrated fitness system 100 includes a mounting support structure 102, straps or straps segments 104a-104d, holds 106a-106d, and attachment members 108a-108b.

Although not depicted, the fitness system 100 may include other components to facilitate the suspension of a user in the air to exercise.

Fitness system 100 may be used to suspend a user in the air. A user may interface the holds 106a-106d of the fitness system 100 and perform a variety of exercises and resistance training all while suspending himself or herself in the air.

For example, a user's hands may interface holds 106a and 106c while the user's feet interface holds 106b and 106d. The use of four holds 106a-106d allows a single user to concurrently interface each hold 106a-106d with a separate hand or foot. Various exercises may then be performed while suspended in the air.

In the illustrated embodiment each hold 106a-106d is connected to an individual strap 104a-104d. Straps 104a-104d are adjustable in length between a corresponding hold 106a-106d and a corresponding suspension point at an attachment member 108a-108b. For example, strap 104a may be adjusted in length between the hold 106a and the attachment member 108a. In some embodiments, one or all of the straps 106a-106d are adjustable in length. In some embodiments, one or all of the straps or strap segments are not adjustable in length. The straps 106a-106d may be individually adjustable or adjustable together.

While many embodiments may include more than four holds or more than four straps, some embodiments exclude a supporting member, swing, hammock, strap, seat, or other mechanism to support some or all of a user's torso. Some embodiments herein omit such structures to support a user's torso. The absence of a torso supporting mechanism forces the user to balance and re-balance throughout a workout, therefore engaging all of the user's muscle groups for a comprehensive workout in a short period of time. Workouts may include strength and resistance training, cardio training, running, and workout routines that target muscle groups. Many of these workouts may be accomplished with little to no impact compared to running and jumping of traditional workouts.

The straps 104a-104d are connected to attachment members 108a and 108b. The number of attachment members 108 may vary. In some embodiments, all straps 104a-104d are attached to a single attachment member 108. In some embodiments, each individual strap 104a-104d is attached to a separate attachment member 108. In the illustrated embodiment, straps 104a and 104b are connected to attachment member 108a while straps 104c and 104d are connected to attachment member 108b. Attachment members 108a-108b may be, but are not limited to, rings, carabiners, loops, hooks, grommets, or other structures capable of attaching the straps 104a-104d to a mounting support structure 102.

In the illustrated embodiment, the mounting support structure 102 is an A-frame. The attachment members 108a and 108b attach to a cross bar of the A-frame mounting support structure 102. The mounting support structure 102 varies in embodiments, as is illustrated by the embodiments described herein. The mounting support structure 102 may be a pull-up bar or other bar attached to a wall, ceiling, or mounting frame. The mounting support structure 102 may be a hook, a ring, or similar structure attached to a wall, ceiling, or mounting frame. The mounting support structure 102 may be a pull-up bar inserted and supported by a door frame. All embodiments of a mounting support structure 102 are not described herein and include those known by those skilled in the art.

FIG. 2 depicts one embodiment of a fitness device 200 for suspending a user in the air with adjustable straps, 104e and 104g, and elastic straps, 104f and 104h. Although the illustrated fitness device 200 is shown and described with certain components and functionality, other embodiments of the fitness device 200 may include fewer or more components to implement less or more functionality. With reference to FIG. 2, four strap units are shown. The illustrated strap units include holds 106a-106d (for a hand or foot) attached to adjustable straps 104e and 104g and stretchable or elastic straps 104f and 104h. Adjustable straps 104e and 104g are adjustable via adjustment mechanisms or tension lock buckles 110. The other end of the straps 104e-104h includes or is attached to attachment members 108a and 108b.

Any type of hold may be implemented. The illustrated holds 106a-106d include handles 112a-112d, loops 114a-114d extending away from the handles 112a-112d, and another loop attached to the straps 104e-104h. The handles 112a-112d may be used as a hold for a hand or a foot. Similarly, the loops 114a-114d extending away from the handles 112a-112d may be used as a hold for a hand or a foot. Other embodiments may use other types of holds. Some holds may be specifically configured as a hand hold. Some holds may be specifically configured as a foot hold. Additionally, some holds may be a suitable size to accommodate two hands or two feet. Other holds may have two separate hold locations connected together. The connection between the connected holds may be static so that there is not substantial movement between the connected holds. Alternatively, the connection between the connected holds may be dynamic to allow movement between the connected holds.

Straps 104e-104h may vary in type, material, style, length, adjustability, and other factors. In the illustrated embodiment, straps 104e and 104g are adjustable in length. Straps 104e and 104g employ the use of tension lock buckles 110 to adjust the length of the straps. For example, pulling on the strap segment 104i will shorten the length of strap 104e via the tension lock buckle 110. Adjusting the tension lock buckle 110 to shorten the strap segment 104i will lengthen the strap 104e, thereby increasing the length of the strap between the hold 106a and the attachment member 108a. Those skilled in the art will recognize other ways and other mechanisms that allow the length to be adjusted between the holds and the suspension point or attachment members and are not all described herein, for the sake of brevity. By way of example, though, the length may be adjustable by adjusting where the holds interface with the straps or adjusting where along the straps they are attached to an attachment member.

Straps 104e-104h may be made of any suitable material to support the weight and movements of a user. In one embodiment, the straps are made of nylon webbing or another type of woven webbing, or rope. In the illustrated embodiment, straps 104f and 104h are not adjustable in length, however, they may be made of an elastic material to allow the straps 104f and 104h to stretch and retract during a workout, thereby decreasing impact and increasing dynamic resistance. In some embodiments, the straps are static and may be neither adjustable nor stretchable.

Straps 104e-104h are connected to attachment members 108a and 108b. Attachment members 108a and 108b attach the straps 104e-10h to the mounting support structure 102. In the illustrated embodiment, the mounting support structure 102 is a bar, which may be attached to a solid surface or attached to a suitable mounting frame.

FIG. 3 depicts another embodiment of a fitness device 300 for suspending a user in the air. The fitness device 300 has many features similar to those that are described in FIGS. 1 and 2. In the illustrated embodiment of FIG. 3, strap segments 104k and 104l are segments of one strap. Similarly, strap segments 104m and 104n are segments of one strap. The straps are supported by bar 302 and are made of a static material. Hold 106a is attached to one end of strap segment 104k. Hold 106e includes a loop and a handle 112e. The handle 112e may interface with a hand or foot of the user. Hold 106f includes a loop 114e that may interface with a hand or a foot of the user. Hold 106g includes a loop and a handle 112f. The handle 112f may interface with a hand or foot of the user. Hold 106h includes a loop 114f that may interface with a hand or a foot of the user.

As strap segments 104k and 104l are segments of one strap, when the user pulls on the handle 106e, strap segment 104k may lengthen and increase the distance from hold 106e to suspension point 304a and simultaneously shorten strap segment 104l and decrease the distance from hold 106f to suspension point 304a. When the user pulls on the hold 106f, strap segment 104l may lengthen and increase the distance from hold 106f to suspension point 304a and simultaneously shorten strap segment 104k and decrease the distance from hold 106e to suspension point 304a. Similarly, when the user pulls on the hold 106g, strap segment 104m may lengthen and increase the distance from hold 106g to suspension point 304b and simultaneously shorten strap segment 104n and decrease the distance from hold 106h to suspension point 304b. When the user pulls on the hold 106h, strap segment 104n may lengthen and increase the distance from hold 106h to suspension point 304b and simultaneously shorten strap segment 104m and decrease the distance from hold 106g to suspension point 304b. Bar 302 may utilize bearing, pulleys, or other mechanisms or a smooth surface to allow for the handles 106e-106h to change the distance relative to the bar 302. In the illustrated embodiment, a primarily hand hold 106e is paired with a primarily foot hold 106f. In some embodiment, the hand holds may be paired together or another combination of hands, feet, or hand and foot may be paired.

FIG. 4 depicts another embodiment of a fitness system 400 for fully suspending a user in the air to exercise. The fitness system 400 has many features similar to those that are described in FIGS. 1-3 above and are not specifically described again.

FIG. 4 depicts a pull-up bar station 402 mounted within a door frame 404. The pull-up bar station 402 and the door frame 404 may be the mounting support structure. The pull-up bar station 402 includes brackets 406 and pins 408. The pin 408 sits between brackets 406 to allow the attachment member 108 to be attached to the mounting support structure. The attachment member 108 may be any type of mechanical structure suitable to connect one or more straps to a corresponding mounting support structure (not shown). Some examples of attachment members include, but are not limited to, rings (D-rings, O-rings, etc.), grommets, loops, and carabiners.

FIG. 5 depicts one embodiment of a fitness system 500 with suspension points 502 separate from mounting points 504. The illustrated embodiment depicts two leader straps 104o and 104p extending from a common strap 104s. Two leader straps 104q and 104r extend from common strap 104t. Some embodiments may include two or more leader straps extending from a common strap attached to an attachment member. For example, four leader straps may extend from a single common strap. Every section of the straps may be independently adjustable via tension lock buckles 110 or other length adjustment mechanisms. The straps 104o-104t may be made of any suitable material to support the weight and movements of the user.

In the illustrated embodiment, the common strap 104s is not attached at the ring 506. The ring 506 provides a suspension point 502 and common strap 104s is attached at an attachment point or mounting point 504. Mounting point 504 is attached to a ceiling 508. The mounting point 508 could be on a wall, floor, or another mounting structure. The suspension point and the mounting point may be separate. Some embodiment may use a leverage structure as the suspension point for the straps, and use a different mounting point of the straps. For example, the straps mount to a wall, but extend over a horizontal bar located at a distance from the wall. In this example, the horizontal bar provides a suspension point because the user would suspend below the horizontal bar, even though the mounting point is not above the user.

An accessory 512 may be attached to a strap unit. FIG. 5 illustrates a mobile device attached to the strap 104t near the ring 506. Examples of accessories include, but are not limited to, pads, electronics, timers, motion sensors, counters, tags, touch sensors, cameras, music players, strain gauges, and so forth. An accessory may attach to the strap using a clamp, Velcro (or another similar engagement material), hooks, and so forth.

FIGS. 1-5 describe many features and functions of embodiments. Although not describe, such features and functions may be combined in any suitable manner. Other embodiments may include two straps to attach to chains on a swing of a swing set. Each strap can attach to a separate chain. Alternatively, two or more straps can attach to the same chain. The user can utilize holds attached to the strap in combination with the seating platform of the swing in order for the user to achieve a full-suspended fitness position. Other embodiments may include a mounting support structure to attach to a piece of outdoor equipment such as a vertical or horizontal pole of a swing set. The mounting support structure includes a strap, clamp, brace, or other mechanical attachment to attach the mounting support structure to the supporting equipment. The mounting support structure also includes one or more attachment points to attach one or more strap units. Other embodiments may include more than four straps for a single user, three handles/holds for a single user, or four holds for a single user. Other embodiments may include an attachment structure for straps used by different users.

Straps may be static with substantially no elasticity or dynamic with some amount of elasticity. The elasticity may be over the full length of the straps or over a fractional portion of the straps. The elasticity may be implemented to limit the fully-stretched length of the strap within a specific range. Any combination of static and dynamic straps may be used and each strap may be individually adjustable in length. Any number of straps attached to a single attachment member. Some embodiments may include dynamic movement of two corresponding straps, so that movement of one strap results in corresponding movement of another strap. In one embodiment, the attachment member may allow movement of the strap relative to the attachment member. For example, pulling on one strap increases the strap length between the hold and the attachment member, and simultaneously decreases the strap length of another strap. The increased strap length of the first strap corresponds to the decreased strap length of the second strap. Some embodiments may include dynamic movement of more than two corresponding straps. Pulling on one strap results in changing the length of two or more corresponding straps Some embodiments may include Some embodiments may include straps that have relatively small cross-sectional areas and substantially fixed cross-sectional geometries in order to provide a simple system that does not tend to interfere with the user. Some embodiments are specifically implemented with adjustable straps that allow a user to independently change the length of the strap between the attachment member and the corresponding hold(s).
