CROSS-REFERENCE TO RELATED APPLICATIONSThe present application claims priority to U.S. Provisional Application No. 62/441,877 entitled “REHABILITATION FITNESS AND EXERCISE SYSTEM” filed Jan. 3, 2017, and hereby expressly incorporated by reference herein.
TECHNICAL FIELDThe present invention relates to exercise apparatus. More specifically, the present invention relates to systems and techniques for exercising using resistance bands and other such devices.
BACKGROUNDIn the fitness industry, a plethora of machines and devices have been used to facilitate muscular development, body health, and overall fitness. While more expensive and sophisticated machines are common in schools, gyms and health clubs, a need has existed in the art for less expensive alternatives for use in these environments and in the home. One such alternative is the resistance band.
Resistance bands provide an inexpensive yet effective exercise alternative with resistance based on body weight and angle, a variety of exercise options and a relatively extensive range of motion. In addition, resistance bands are portable, lightweight and easy to set up.
Resistance bands usually have a length of woven nylon or other flexible material terminated at each end with a plastic grip. The grip is typically a plastic tube or a foam covered strap. Many exercises require a user to grip the plastic tube with a hand or insert a foot into the strap.
Inasmuch as the typical simple tubular plastic grip or foam covered strap is uncomfortable and ineffective in holding ones extremities in many exercise positions, an open loop, sling or handle puts a tremendous amount of pressure on the joints when used to support one's bodyweight, and in many cases, may cause injury to joints. This is particularly problematic with people having weaker joints or a weak grip. If a person has a weak joint, it further exposes them to injuries, especially injury to the elbow, ankle or knee joints. Whether it's TRX®, training straps, or elastic bands, the user must depend on either the wrist or ankle joint to support and stabilize their bodyweight. Hence, excessive pressure is often placed on the joints in reliance on them for support and stabilization.
Accordingly, a need exists in the art for an improved resistance band design that offers the advantages of conventional resistance bands with an improved body weight support implementation.
SUMMARYVarious implementations of systems, methods and devices within the scope of the appended claims each have several aspects, no single one of which is solely responsible for the desirable attributes described herein. Without limiting the scope of the appended claims, some prominent features are described herein.
Details of one or more implementations of the subject matter described in this specification are set forth in the accompanying drawings and the description below. Other features, aspects, and advantages will become apparent from the description, the drawings, and the claims. Note that the relative dimensions of the following figures may not be drawn to scale.

DETAILED DESCRIPTIONFIG. 1 illustrates an example of fourbands100 assembled to be used individually or as a group. Eachband100 may include aresistance band105. Each end of theresistance band105 is connected to awebbing120. Each end connection can include agrommet110 for securing theresistance band105 to thewebbing120. The end of eachband100 may include a shackle, a metal loop, orother fastener115. For example, the end of eachband100 may include acarabiner115. Thecarabiner115 may be metal and include a spring loaded gate. Thecarabiner115 allows for quickly and reversibly connecting components.
Eachresistance band105 may be formed of a resilient flexible material. For example, theresistance bands105 may include a polymer material such as rubber (e.g., latex or other natural or synthetic polymer material), silicone, or nitrile. Eachresistance band105 may be calibrated to support a specific weight and/or to offer a specific resistance. For example, eachresistance band105 may be calibrated to offer varying resistances (e.g., 50 lbs, 40 lbs, 20 lbs, and 10 lbs) enabling a user to combine a variety ofdifferent bands100 to perform different exercises and to adjust the tension/resistance and intensity of the exercises. The example resistances provided are not intended to be limiting, as eachresistance band105 may include a resistance selected from a wide range of values. In one implementation, the combined resistances of thebands100 may support the bodyweight of the user, thereby generating a “negative resistance” so that less than the entire bodyweight of the user resists exercise movements of the user.
FIG. 2 illustrates an example of aseat205 for supporting the user's bodyweight during exercise. In certain embodiments, theseat205 may include a cushion material such as foam or cloth, for example, in order to absorb the impact from the user's bodyweight against theseat205. The cushion material may be releasably attached to theseat205. Theseat205 may have a smooth or textured surface made from a flexible, resilient material such as cloth, rubber, mesh, elastic, plastic, or leather, for example. In certain embodiments, theseat205 is made from a material that is easily cleaned after use. Theseat205 is capable of conforming to the user, and providing stability to the body of the user when the user is supported by theseat205.
Each end of theseat205 may include asupport210. Thesupport210 may be a shackle, a loop, or other structure configured to couple with a corresponding engagement in order to support theseat205. For example, thecarabiner115 of eachband100 may be releasably attached to thesupport210 of theseat205. Thesupport210 may be attached to theseat205 using any material with a high tensile strength. For example, Kevlar, Dacron, Nomex, and Nylon. In certain embodiments, a first end of thesupport210 is fixed to theseat205 with a second end of thesupport210 configured to releasably receive thecarabiners115 of thebands100.
Theseat205 may generally have a U-shape when the system is assembled. In certain embodiments, the legs of the U-shape (i.e., end portions of the seat205) are made from a rigid material while the web connecting the legs (i.e., center portion of the seat205) is made from a cloth material. The legs may provide a connection point for the one ormore carabiners115 that is spaced from the center portion of theseat205 so as to inhibit contact between thebands100 and a user's midsection.
FIG. 3 illustrates an example of anexercise system300 in a disassembled state. Theexercise system300 may include at least two groups ofbands100 that incorporate a variety ofresistance bands105 and theseat205. In certain embodiments, the exercise system further includes one ormore sleeves310 to cover and organize the selectedbands100 for each side of theexercise system300 when assembled.
Eachsleeve310 is configured to at least partially cover and organize thebands100 selected for each side of theexercise system300. In certain embodiments, thesleeve310 has a tubular open ended shape. In certain embodiments, thesleeve310 is made from a flexible material or rigid material. In certain embodiments, thesleeve310 is made from a resilient, flexible material such as polyester, for example. In certain embodiments, the sleeve is made from a plastic or other rigid structure. Thus, it is understood that other materials can be used as desired.
In certain embodiments, thesleeve310 may include a zipper or Velcro that runs the length of thesleeve310 so that thesleeve310 can be opened to add and/or removebands100 from thesleeve310 or remove thesleeve310 from theexercise system300. For example, thesleeve310 may be removed from theexercise system300 to facilitate the change ofbands100 selected for use with theexercise system300. In certain embodiments, the length of thesleeve310 is selected so that the user can access one or both ends of theband100 to attach the end to theseat205 or a secure object, such as an overhead assembly, without removing thesleeve310.
Eachsleeve310 may include one ormore attachment elements305. In certain embodiments, theattachment elements305 are disposed at either end of thesleeve310. In certain embodiments, the one ormore attachment elements305 attach to the open-ends of thesleeve310. Theattachment elements305 may include a material such as metal, for example, capable of withstanding the body weight of the user when theexercise system300 is in use. Of course, other materials may also be used.
In certain embodiments, theattachment elements305 comprisecarabiners355 or other fasteners. Theattachment elements305 are capable of releasably connecting to both thesupport210 of theseat205 on one end and an overhead assembly (not shown) on the other end.
In certain embodiments, the one ormore attachment elements305 are part of thesleeve310 or can be a separate structure that is attachable to thesleeve310. For example, thesleeve310 illustrated inFIG. 3 includes theattachment element305 nearest to theseat205 while theattachment element305 nearest to the overhead assembly is a separate structure from thesleeve310. In the illustrated embodiment, theattachment element305 nearest to the overhead assembly forms a separate assembly with astrap360.
In the illustrated embodiment, thesleeve310 comprises abuckle350 configured to releasably secure thestrap360 thereby securing theattachment element305 relative to thesleeve310. The length of thestrap360 is adjusted to allow a user to increase or decrease the distance of thesleeve310 and/orseat205 relative to the overhead assembly or floor. For example, by adjusting the length of thestrap360 between thebuckle350 and theattachment element305, the user may adjust the height of theseat205 relative to the floor.
It will be understood that theseat205 may be inflexibly supported to the overhead assembly by thesleeve310 when theattachment elements305 nearest to theseat205 are attached to theseat205. In this way, the user is supported inflexibly at a certain height above the floor. This configuration may be advantageous for the user to become familiar with theexercise system300 or for performing exercises where it is desirable to maintain a fixed distance between theseat205 and the floor. Of course, once theattachment elements305 nearest to theseat205 are disengaged from theseat205, thebands100 connected to theseat205 will then flexibly support the user.
In certain embodiments, thesleeve310 includes more than onebuckle350 disposed at different locations on thesleeve310. In the embodiment illustrated inFIG. 3, thebuckle350 is disposed at an end of thesleeve310 nearest to the overhead assembly.
In certain embodiments, thebuckle350 is disposed at an end of thesleeve310 nearest to theseat205. In such an embodiment, thebuckle350 can releasably secure thestrap360 thereby securing theattachment element305 relative to thesleeve310. Theseat205 can then be secured to theattachment member305.
Eachsleeve310 may include one or more elements or rings325. In certain embodiments, eachring325 is metal and has a 2 inch diameter. Of course thering325 is not limited to a specific material, size, or shape.
In certain embodiments, thering325 is disposed inside thesleeve310. In certain embodiments, thering325 is fixed to thesleeve325. For example, in certain embodiments, thering325 is sewn into a webbing spline. In certain embodiments, the webbing spline runs along a length of thesleeve310. In certain embodiments, the spline is on an inner surface of thesleeve325 and further connects to thebuckle350 at an end of thesleeve310 nearest to the overhead assembly. In certain embodiments, an end of theattachment member305 nearest to theseat205 is sewn into the spline.
The one ormore rings325 may be disposed and secured inside thesleeve310. Themetal carabiner115 of eachband100 may be selectively attached to one or more of therings325. The one ormore rings325 may vary in number, and in diameter and thickness, but in one exemplary embodiment, eachsleeve310 may include threerings325 on an outer surface of thesleeve310 and one ring on an inner surface of thesleeve310.
In certain embodiments, ends of thebands100 pass through and out of thesleeve310 to connect directly to the overhead assembly via thecarabiners115. In certain embodiments, ends of thebands100 pass through and out of thesleeve310 to connect to the seat205 (e.g.,carabiner115 may connect to support210). Thus, in certain embodiments, thesleeve310 may or may not be a load bearing member between theseat205 and the overhead assembly. In some embodiments thecarabiner115 may be attached to themetal ring325 in thesleeve310, and the sleeve may be attached to the overhead assembly and/or theseat205 via theattachment elements305.
Theattachment elements305 may be connected to thesleeves310 using the spline that runs the length of thesleeve310. In one example, the spline includes a fabric such as woven cloth, nylon, or Kevlar, for example. The spline may include theattachment elements305 on each open-ended side of thesleeves310. In this configuration, the spline can connect one end of thesleeve310 to a stable component and support a user on theseat205 attached to the other end of thesleeve310. Eachsleeve310 may also include a number ofattachments elements305 and splines on the outer surface of thesleeve310 to accommodate simple attachment and removal of peripheral attachments. For example, the user may attach an exercise handle orexercise bar330 to the outer surface of thesleeve310 to facilitate comfortable grip. In certain embodiments, the exercise handle330 may be attached to an end of theband100.
Still referring toFIG. 3, eachsleeve310 may include one or more handles330. Thehandle330 may extend substantially linear from an upper edge of thesleeve310 to a bottom edge of thesleeve310, thereby facilitating ergonomic utility of eachsleeve310. In one example, eachsleeve310 may include a consecutive number of handles running vertically up thesleeve310 to support users of different height. Each handle330 may include a hand grip enabling the user to firmly grasp thehandle330 with the hand during specific modes of exercise. The hand grip may include a textured layer to facilitate stable grip of thehandle330. Thehandle330 may be a hollow, rigid element such as a PVC pipe, for example. Other rigid materials such as alternative types of plastic or metal may also be used to form thehandle330. In other embodiments, thehandle330 is not hollow. Thehandle330 may have a slight curvature or arch along a length of the handle that corresponds to the curvature of the user's hands. The curvature allows for the user to maintain a comfortable and stable grip of thehandle330 while theexercise system300 is in use. In one embodiment, each handle330 may be attached to an adjustable length strap of material attached to thesleeve310 to allow a user to modify the position of thehandle330 for performing different workouts. In one example, the material may be polypropylene, polyester, or nylon, woven in a webbing pattern. The example materials provided are not intended to be limiting, as each adjustable length strap may include any material or blend of materials.
Still referring toFIG. 3, eachsleeve310 may include one or more metal rings340. The one or more metal rings340 may be attached to the outside of thesleeve310 for attaching additional handles or other peripheral workout equipment. The one or more metal rings340 may vary in number and in diameter and thickness, but in one example embodiment, eachsleeve310 may include threemetal rings340 attached to the outside of thesleeve310, and eachmetal ring340 may have a 1 inch diameter.
In certain embodiments, thehandle330 connects to the overhead assembly, a carabiner or fastener (not shown) connected to the overhead assembly, an end of theband100, and/or thesleeve310.
FIG. 4A illustrates an example implementation of thebands100 and thesleeve310. Thering325 at the upper end of thesleeve310 may attach to thecarabiner115 of a variety ofbands100. Thesleeve310 may surround thebands100 to provide protection to the user and organize thebands100. For example, thesleeve310 can prevent abroken band100 from contacting or injuring the user. The zipper of thesleeve310 may also provide the user with an easily accessible way to add or remove one ormore bands100 from theexercise system300.
FIG. 4B illustrates an end of thesleeve310 fromFIG. 4A that is closest to the overhead assembly. InFIG. 4B, thesleeve310 has been pulled in a downward direction to expose thering325. Thering325 and thebuckle350 may be attached to thesleeve310, for instance, by way of a double folded box-stitch.FIG. 4B illustrates thesleeve310 with the length of thestrap360 removed from thebuckle350. As described above with reference toFIG. 3, thebuckle350 andstrap360 may be used to adjust the height of thesleeve310 and/or theseat205 relative to the overhead assembly.
FIG. 5 illustrates an example of an assembledexercise system300. Theexercise system300 may include twosleeves310 containing a plurality ofbands100 in eachsleeve310. Thesupport210 of theseat205 may be connected to either of the bottom edgesleeve attachment element305 or the bottom end of any of the one ormore bands100, on each side. Theattachment elements305 at the upper edges of bothsleeves310 may connect to a secure object of the overhead assembly (not shown), for example a ceiling beam, a door, a door frame, a wall, or other secure, substantially rigid object. The upper edges of bothsleeves310 may connect to the secure object a distance apart from each other so that the user may rest on theseat205 without interference from other elements of theexercise system300. Thecarabiners115 at the top end of thebands100 may also connect to the secure object, or in certain embodiments, to a second attachment element of the upper end of the sleeves310 (e.g., metal rings325).
Once theexercise system300 is adequately secured, the user may sit or lean into theseat205 with a front midsection, a back midsection, or a side midsection. In certain embodiments, the user may use their hands to grasp thehandles330 for support. The user then performs exercises and/or stretches such as cobra stretches, back extensions, pull-ups, push-ups, and squats. Theexercise system300 is also configured to permit three dynamic modes of exercise, i.e., passive motion, assisted active motion, and independent active motion.
The user may vary the complexity and difficulty of the exercises and stretches by altering an angle at which the user stands relative to a floor and thereby altering the amount of the body weight of the user against which the user is working. Additionally, the user may alter the number ofbands100 in eachsleeve310 to increase negative resistance and/or body weight support.
The above-describedexercise system300 has several advantages. First, unlike other suspension trainers, theexercise system300 provides a means for upper body and midsection exercises and stretches for the user who is unable to support their own bodyweight. Such exercises are beneficial for rehabilitation and strengthening of weak muscle groups. Theexercise system300 is further configured to allow the user to adjust the height of theseat205 and the resistive strength of thebands100. Accordingly, exercises and stretches such as back extensions and cobra stretches, for example, may be performed. Additionally, theexercise system300 is versatile in that it may be used with other suspension trainers by connecting theattachment elements305 andbands100 to the other suspension exercise assemblies.
FIGS. 6A and 6B illustrate a first or starting position and a second or ending position, respectively, for a push-up exercise using theexercise system300. This exercise offers a rehabilitative range of motion exercise of joints associated with the elbows and shoulders, and chest and arm muscles. To operate theexercise system300 in this manner, the user's midsection is laid over theseat205 such that thebands100 pull theseat205 to fit the form of the user midsection. With toes and hand palms on the ground, the body is suspended in balanced isolation between thebands100, from which the user may actively push up to raise the body and activate various muscle groups. For the independent active motion mode of exercise, the user drives the body upward using chest and arm muscles, and slowly releasing muscle tension to return to the starting position. Accordingly, theseat205 is organically connected to the user's midsection, enabling theseat205 to intrinsically align with the anatomical structure of the midsection without requiringstrict seat205 alignment or fastener adjustment.
FIGS. 7A and 7B illustrate a first or starting position and a second or ending position, respectively, for a squat exercise using theexercise system300. This exercise offers a rehabilitative range of motion exercise of joints associated with the ankles, knees, and hips, as well as leg and backside muscles. To operate theexercise system300 in this manner, the user sits in theseat205 such that thebands100 pull theseat205 to fit the form of the user's backside. With feet planted flat on the ground, the user is suspended in a seated position (starting position) from which the user may push (i.e., stand) up. For the passive motion mode of exercise, the user grips thehandles330 with at least one hand. Applying the users own upper body muscles, the user alternately raises and lowers the users body to achieve alternate passive flexion and extension exercise of the knee and hip joints through the desired range of motion. The same process may also be used to achieve a passive motion mode of exercise of the arms and shoulders. For example, the user may grip thehandles330 with each hand while driving the body upward with the legs to cause pivotal motion in the shoulders and elbows. The same procedure is repeated for the assisted active motion mode of exercise, but the user partially drives upward to a standing or near standing position using the leg muscles, augmenting the drive applied by the upper body muscles to exercise the knee or hip joint through the desired range of motion. For the independent active motion mode of exercise, the user releases the grip on the rotation bar entirely and drives upward in a standing or near standing position solely using the user's leg muscles.
FIGS. 8A and 8B illustrate a first or starting position and a second or ending position, respectively, for a pull-up exercise using theexercise system300. This exercise offers a rehabilitative range of motion exercise of joints associated with the shoulders and elbows, as well as back and arm muscles. To operate theexercise system300 in this manner, the midsection of the user's backside is laid over theseat205 such that thebands100 pull theseat205 to fit the form of the user. With legs extended out, feet on the ground, and hands gripping thehandles330, the body is suspended in balanced isolation between theweight bands100, from which the user may actively pull up to raise the body and activate various muscle groups.
Although the foregoing has been described in connection with various different embodiments, features or elements from one embodiment may be combined with other embodiments without departing from the teachings of this disclosure. However, the combinations of features between the respective embodiments are not necessarily limited thereto. Various embodiments of the disclosure have been described. These and other embodiments are within the scope of the following claims.
