DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] An improved exercise device is disclosed herein. The exercise device includes an improved structure which provides adequate resistance strength for strength training while stretched and is configured to be worn when not in use as a convenience and motivational instrument.

[0020] In some embodiments, the device can be manufactured using latex resistance bands as an exemplary material. However, it should be appreciated by a person of ordinary skill in the art that other materials, such as rubbers, plastics, composites, or the like can be used either alone or in combination. The device allows for a user to exercise various muscles in the body, which can include: muscles in the arm (such as biceps, brachioradialis, extensor carpi radialis longus, deltoids, triceps, and others), muscles in the chest (such as pectoralis minor and major, derratus anterior, and others), muscles in the back (such as rhomboids, trapezius, and others), muscles in the leg (for example, hamstrings, adductors, quadriceps, gastrocnemius, soleus, tobialis anterior, and others), and core muscles like the abdomen. Other muscles can be worked out depending on the multiple ways of holding the device and the various configurations as described herein. In some embodiments, the devices can be manufactured with varying elasticity or resistance strength as well as length such that difference exercises can be performed to work out muscles in difference parts of the body and to a degree that is desired by a user of the device.

[0021] In some embodiments, the device can be manufactured with varying elasticity, or magnitudes of resistance strength. For example, resistance strengths can include a light, medium, and heavy configuration, among others. The device structure can be modified to match the resistance strength needed by a user of the device within a certain threshold tolerance. Also, the device can be manufactured with varying lengths. In some cases, different materials can be used to achieve the correct elasticity. In other cases, a different structure can be used (for example, braiding multiple portions of one material together as shown in FIG. 1A and described in more detail below) to achieve the same elasticity. Even in other cases, a combination of different materials and device structures can be used to meet the desired elasticity and length of the device, as well as any other particular needs of the user. For example, a user can desire to have a very short length device manufactured with a heavy configuration for the resistance strength. This can be achieved by using a less elastic material cut to the appropriate length, or the same material but wrapped or braided together with 1 or more strands of the material, for example, FIG. 1A depicts a braided configuration of two strands of a latex material. It should be appreciated that any number of strands can be braided with various techniques (for example, a one-strand braid, a two-strand braid, a three-strand braid, a four-string braid, or more). Also, braiding can be performed in various patterns, such patterns can comprise regular braiding as depicted in FIG. 1A, kumihimo (for example, round, half round, hollow, square, spiural, seven cord, or others), box, loop, or others. Additionally, each strand can comprise a varying width and varying elasticity or resistance. For example, a braid of three strands can comprise two strands of light resistance and one strand of medium resistance in the exercise device. It should be appreciated that any combination of resistances and widths can be used in the exercise device.

[0022] In some embodiments, the device can comprise of three strands of latex, intertwined, or braided, to form a uniform and interlaced strip which, in some embodiments, can be tied into a knot at each end. The braided configuration of the device is advantageous because it allows for greater durability and strength of the material as well as providing a unique and aesthetically pleasing design. The grip provides both grip and design for the product. The grip is used throughout the exercise as a grip handle in order for the user to easily hold the product while performing exercises. For example, a user can hold a grip where the grip is resting on the web of the user's hand between the thumb and index finger in the palm of the user's hand. As a user may sweat or have slippery palms, the grips are configured to be held when friction between the user's palms and the device is lubricated by the sweat or for any other reason. It should be appreciated that the device can comprise one or more materials in various embodiments, such as: latex, rubber, foam, TPE (thermoplastic elastomer), cotton blends (e.g. cotton blends with rubber or polyester), or any mixtures or combinations of such materials or similar materials. For example, a device with a braid of three strands can comprise one strand comprising latex, another strand comprising TPE, and a third strand comprising a cotton-polyester blend. It should be further appreciated that varying combinations of materials into one device (e.g. by braiding them together) can be designed based at least partly on the material properties associated with each of the materials to be used in the device, as well as, in some cases, the properties of the resulting device. For example, it may be desired to have a device with the measured elasticity of the device to be within a certain range. There can be many combinations of varying materials, each with its own material properties, to be braided in such a way as to achieve the desired elasticity of the device. Further, in some embodiments, a human user may want to increase the resistance provided by only one device (e.g. device A) for a particular exercise, and can hold two devices (e.g. devices A and B) together to perform the particular exercise with the desired resistance. For example, multiple devices (e.g. devices A and B) with varying or similar elasticity can be connected by the magnets on the ends such that the elongate bodies are parallel to each other, and/or, for example, magnet A of device A can be connected to magnet B of device B, and magnet B of device A can be connected to magnet A of device B.

[0023] In some embodiments, the device ends can clasp together for storage or for safe-keeping by wrapping the device around an arm, leg, backpack, purse, or the like. In some embodiments, where latex is used in the exercise device, after tying the ends of the strands of the exercise device into knots (for example, one knot at each end), there can be excess material at the end of each knot. The excess material, which is described herein as a free end, can be connected or secured to a latching mechanism or securing device. In some embodiments, the securing device can comprise a magnet, clasp, clamp, hook, buckle or the like. In some embodiments, the excess material on one end of the device can be configured to be tied to the other end of the device. Once the two ends are connected, the device can resemble a bracelet shaped accessory. It should be appreciated that the latching mechanism can be designed with a minimal strength such that the connection can withstand intermittent contact with surfaces (for example, being brushed against a wall) and still remain connected.

[0024] Further the latching mechanism can be designed with a method of detachment such that a user can use an appropriate level or force or effort to detach the two ends. Also, while a user holds a grip on the web of the user's hand between the thumb and index finger in the palm of the user's hand, as described above, the end of the device would also be in the palm of the user's hand, and, in some embodiments, it is desirable for the device to have a securing device that is both small and not obtrusive. A user would not find a large or hard clasp or buckle comfortable to hold (e.g., in a hand or under a leg as illustrated in certain exercises below) with certain exercises. Thus, in some embodiments, the device does not comprise a securing device larger than the average diameter of the grip or harder than the device material.

[0025] In some embodiments, the device can advantageously be used in any place and at any time with a limited amount of space to work out. For example, unlike body weight exercises that require relatively large floor or wall space to work out, the device can be used while seated or standing without fully extending ones arms outward. Additionally, in some embodiments, the device can be configured to attach to wrists as a bracelet, keychains, travel and handbags, as well as other items. Due to the increased portability and small size of the product, users will be able to exercise anywhere, at any time, with the broad range of motions offered by body weight training but with the results of free weight or machine training.

[0026] With respect to the material characteristics, as an indicator of elasticity, Young's modulus can be used. Young's modulus can be represented in the following formula, where Y is Young's modulus, F is the force applied in Newtons to the solid, A is the cross-sectional area of the solid in meters squared, L is the stretched length of the solid, and L0 is the original length of the solid. Thus, a solid with a greater value of Y will stretch less than a solid with a smaller Y, when the same force is applied.

[00001]$Y=\frac{F.Math.\text{/}.Math.A}{.Math..Math.L.Math.\text{/}.Math.{L.Math.}_0}$

[0027] In some embodiments, the Young's modulus can range from 110.sup.4 N/m.sup.2 to 210.sup.5 N/m.sup.2. However, the Young's modulus in some embodiment can range from 3.510.sup.4 N/m.sup.2 to 1.410.sup.5 N/m.sup.2. It should be appreciated that the inventions as disclosed herein can also be designed with a Young's modulus that is lower than 1 x 10.sup.4N/m.sup.2 or higher than 210.sup.5N/m.sup.2 and still be used for its intended purposes. It should also be appreciated that the Young's modulus can also vary based on the desired resistance strength (i.e. elasticity) of the device. Some users may prefer a higher resistance device and/or a thicker device and both variations can affect the Young's modulus.

[0028] Additionally, an adapted form of Young's modulus can be used to measure the elasticity of elastic bands. This adapted form is known as Hooke's Law, which is classically applied to spring systems, but can also be used to describe the strength patterns observed in elastic bands for relatively small applied forces. The Hooke' s Law formula follows, where F is the force applied to the elastic material in Newtons, k is the spring constant in Newtons per meter, and L is the change in length of the elastic material in meters.

F=k L

[0029] To Estimate for k, the following equation can be used:

[00002]$k=\frac{\mathrm{mg}}{.Math..Math.L}$

[0030] Although Hooke's law is a loose estimation for elastic devices, such as some of the embodiments disclosed herein, it can be used to estimate elasticity. The spring constants of the devices used in the Hooke' s Law calculations disclosed herein can range from 20 N/m to 120 N/m. In some embodiments, the devices have spring constants in the ranges of 35 N/m to 110 N/m. It should be appreciated that some embodiments, as disclosed herein, can also be designed with a spring constant that is lower than 20 N/m, or a spring constant that is higher than 120 N/m, and the device can still be used for its intended purposes. It should also be appreciated that the spring constant in Hooke's Law can also vary based on the desired resistance strength (i.e. elasticity) of the device. Some users may prefer a higher resistance device and/or a thicker device and both variations can affect the Young's modulus.

[0031] Each of the strands in the exercise device, as described in more detail herein and in FIGS. 1 and 2, can include free ends 108A and 108B, and can be designed with varying elasticity or resistance. For example, the Hooke' s Law spring constant for each strand can range from 5 N/m to 60 N/m. In some embodiments, for example, the spring constant in Hooke's Law can range between 5 N/m to 15 N/m for light rated strands; 15 N/m to 30 N/m for medium rated strands; and 30 N/m to 50 N/m for heavy rated strands. It should be appreciated that strands can have a spring constant in Hooke's Law that is lower than 5 N/m or higher than 50 N/m that are used in the exercise device. In some embodiments, the free ends 108A and 108B in FIGS. 1 and 2 can comprising the same materials as the elongate body 102 such that wearing the device would be comfortable to a human user when in contact with the human user's skin.

[0032] With reference to FIGS. 1 and 2, which depict an exemplary embodiment, the exercise device 101 comprises an elongate portion 102, two ends 110A and 110B. Each end comprises a gripping component or mechanism 104A and 104B, a latching mechanism or securing device 106A and 106B, and one or more free ends 108A and 108B. Specifically, FIG. 1A depicts the exercise device 101 in a resting position (i.e. not stretched) and straightened out. FIG. 1B depicts the same exercise device 101 at a resting position (i.e. not stretched) an instance prior to attaching the securing device 106A with securing device 106B, which in this instance are depicted as magnets. The gripping components 104A and 104B can comprise in some embodiments the same materials as the materials comprising the elongate body 102 such that a holding the gripping components would be comfortable to a human user. For example, in one configuration, a user may grip the exercise device at one gripping component 104A, for example, and will have a portion of the exercise device 101 in the curled portion of the user's fingers and hand (for example, a portion of the elongate body 102), and the edge of the gripping component 108A facing towards the elongate body 102 in contact with the user's edge of their curled fingers. The continuous contact with both the elongate body 102 and gripping component 104A may be more comfortable to some users if the material of both components of the exercise device were constructed of the same material to provide a less discontinuous textured feeling. Additionally, in some embodiments, the length between the centroid of one gripping component 104A, for example, to the centroid of a second gripping component 104B, for example, as measured along the longitudinal axis of the elongate body 102 can range from five inches to ten inches or eleven inches to twenty-one inches such that a human user can perform exercises with the device comfortably and wrap the exercise device around the user's arm once or twice, respectively.

[0033] Optionally, the gripping components 104A and 104B can be created by tying the material into one or more knots. This can prevent a braided configuration from coming undone and also enable efficient and effective gripping of the device by a user. For example, a user can hold gripping component 104A with a right hand and gripping component 104B with a left hand and stretch the device apart across the user's chest, back, or head repetitively for a work out. Specifically, one arm can stay stationary while the other arm moves or both arms can move apart together, to focus on particular muscles. Additionally, if a user is seated, the gripping component 104A can be placed under the user's leg and held in place by the surface upon which the user is sitting and the user's leg, allowing the user to hold gripping component 104B in a hand and pull the end 110B away from 110A for resistance. For example, the user can do curls in a seated position. Also, a user can hold one of the gripping components 104A and 104B in each hand and wrap the elongate portion 102 around a foot and slowly extend the foot to increase resistance. Although some methods of exercise and use have been described, it should be appreciated that many other methods of use can be implemented by a user to work out many different muscles in the user's body. For example, any surface can be used to hold or secure one or both ends of the exercise device as shown in FIGS. 2A-2B and further described herein.

[0034] After tying the device's ends to form the gripping components 104A and 104B, there can be excess material 108A and 108B, respectively, at the end of each knot. The excess material 108A and 108B is described herein as a free end. In some embodiments, the excess material on one end of the device 110A can be configured to be connected to the other end 110B of the device. In some embodiments, the excess material 108A and 108B can include a latching mechanism or securing device 106A and 106B. The securing devices 106A and 106B can comprise a magnet, clasp, clamp, or the like. FIGS. 1 and 2 depict a magnet as an exemplary embodiment for securing devices 106A and 106B.

[0035] Once the two ends 110A and 110B are attached, the device can resemble a bracelet shaped accessory. Thus, the device ends 110A and 110B can attach together for storage or for safe-keeping by wrapping the device around an arm, leg, backpack, purse, or the like. It should be appreciated that the latching mechanisms or securing devices 106A and 106B can be designed with a sufficient strength such that the connection can withstand intermittent contact or impacts with surfaces (for example, being brushed against a wall) and still remain connected. Further the latching mechanism or securing devices 106A and 106B can be designed with a method of detachment such that a user can use an appropriate level or force or effort to detach the two ends.

[0036] In some embodiments, the latching mechanisms can comprise a first magnet 106A and a second magnet 106B, wherein the first magnet 106A is configured to be detachably connected to the second magnet 106B. The first magnet 106A can be secured to the one or more free ends 108A on the first end 110A and optionally, secured at least half an inch from the first gripping component 104A at a point where the free end 108A connects to the gripping component 104A. The second magnet 106B can be secured to the one or more free ends 108B on the second end 110B and optionally, secured at least half an inch from the second gripping component 104B at a point where the free end 108B connects to the gripping component 104B.

[0037] In some embodiments, the first and second magnet 106A and 106B comprise a smaller physical volume than the gripping components 104A and 104B such that the first and second magnets 106A and 106B are not obstructing a human user from holding the two gripping components 104A and 104B in the human user's hand or one gripping component 104A, for example, in one hand and the other gripping component 104B, for example, against at least one flat surface. In some embodiments, the length between the first magnet 106A and the second magnet 106B as measured along the longitudinal axis of the elongate body 102 is five inches to ten inches such that a human user can wrap the device around the human user's arm one time. In other embodiments, the length between the first magnet 106A and the second magnet 106B as measured along the longitudinal axis of the elongate body 102 is eleven inches to twenty-one inches or two times. Yet in other embodiments, the length between the first magnet 106A and the second magnet 106B as measured along the longitudinal axis of the elongate body 102 can be less than five inches, between five inches and ten inches, between eleven and twenty-one inches, or more than nineteen inches depending on how a human user chooses to store and/or use the device. For example, a user can wrap the exercise device 101 around the user's arm or wrist once (e.g., 5-10 inches), twice (e.g., 11-21 inches), three times, or more. In some embodiments, a user can wrap the exercise device 101 around a leg, waist, or other part of the body. In some embodiments, a user can wrap the exercise device 101 around a purse strap, backpack strap, or the like. Thus, the length of the exercise device 101 can vary based on what the object(s) the user intends to wrap the exercise device 101 around.

[0038] FIG. 1C is a schematic diagram of an embodiment of a three-strand exercise device 301, which can comprise an elongate portion 202 similar to the elongate portion 102 in FIGS. 1 and 2. The embodiment in FIG. 1C can also include gripping components 204A and 204B, which can be similar to gripping components 104A and 104B. Such embodiments can also include latching mechanisms 206A and 206B, which are similar to latching mechanisms 106A and 106B. In some embodiments the three strands in the elongate portion 202 can be braided in various configurations as described herein. It should be appreciated that any number of strands can be braided with various techniques (for example, a one-strand braid, a two-strand braid, a three-strand braid, a four-string braid, or more). Also, braiding can be performed in various patterns, such patterns can comprise regular braiding as depicted in FIG. 1A, kumihimo (for example, round, half round, hollow, square, spiural, seven cord, or others), box, loop, or others. Additionally, each strand can comprise a varying width and varying elasticity or resistance. For example, a braid of three strands can comprise two strands of light resistance and one strand of medium resistance in the exercise device. It should be appreciated that any combination of resistances and widths can be used in the exercise device.

[0039] FIGS. 2A and 2B illustrate one potential exercise that can be performed with the exercise device 101. For example, FIG. 2A is a top view of a person in a seated position holding an exercise device 101 with one end 110B in one hand and positioning the other end 110A between an inner thigh and a chair in preparation for an exercise, according to various embodiments. The user can place the exercise device 101 under one of the user's legs and have the gripping component or mechanism (e.g., 104A and 104B from FIG. 1) touch the user's inner thigh to remain in place while the exercise is being performed. For example, in FIG. 2A, the user's right hand is holding one end 110B of the exercise device 101 and the other end 110A of the exercise device 101 is held in place by the user's the right leg, the chair, and the user's inner right thigh while in use during the exercise. The elongate body 102 of the exercise device 101 is illustrated in FIG. 2A with one end 110B secured in the user's right hand and the other end 110A anchored under the user's right leg. In some embodiments, the user can place the exercise device 101 underneath both legs so that the gripping component or mechanism on end 110A touches the user's outer thigh of the leg on the opposite side of the user's body from where the user is holding the other end 110B of the exercise device 101. In FIG. 2A, the location would be the outer thigh of the left leg.

[0040] FIG. 2B is a side view of the same person in FIG. 2A showing a range of motion the user can perform with the exercise device 101. A user can begin the exercise in a comfortable position with the user's elbow bent and arm parallel to the user's leg, where the exercise device 101 is not elongated and is at a resting state. The elongate body 102 is illustrated in the resting state in solid lines. The user can then curl the user's right arm, as shown in FIG. 2B, to a location close to the user's shoulder stretching the exercise device 101 beyond the exercise device's resting state so that the user must exert a force greater than the resistance of the exercise device 101 to move the user's arm to the desired location. This exercise can work out the user's bicep, for example. The elongate body 102 is illustrated in a stretched state in dashed lines. The end 110B moves from an initial position (e.g., shown in solid lines) to a final position (e.g., shown in dashed lines) as the user curls the user's right arm. In some modified exercises, the exercise device 101 can be longer or can be stretched to some degree when beginning the exercise. For example, if the user places the exercise device underneath both legs (not shown), the exercise device 101 may be in a relaxed state, for example, if it has a length of 11-21 inches or the exercise device 101 can have a shorter length of 5-10 inches and be stretched to some degree when the user begins the exercise. One of the material properties of the device is that the more the device is stretched, the more force is required to stretch the device further to a point of failure. So, a user may desire to increase resistance for the exercise by beginning the exercise where the exercise device 101 is already stretched to attain a higher resistance force for the exercise and improve the quality of the workout.

[0041] It will be understood that the exercise shown in FIGS. 2A and 2B can be performed by the left arm as well. For example, a user can hold one end 110A of the exercise device 101 in the user's left hand and place the other end 110B of the exercise device 101 underneath the user's left leg. The user can then curl the user's left arm to perform the exercise. This exercise would appear as a mirror image of FIG. 2A if it were to be illustrated.

[0042] FIG. 3 illustrates another potential exercise that can be performed with the exercise device 101. FIG. 3 is a rear view of a person in a standing position holding an exercise device 101 with a grip with both hands showing a range of motion the user can perform with the exercise device 101, according to various embodiments. The user can hold one end 110A of the exercise device 101 with the user's left hand behind the back and the other end 110B of the exercise device 101 with the user's right hand behind the user's head/neck. The user can then extend the user's right arm above the user's head to perform the exercise. The end 110B moves from an initial position to a final position as the user extends the user's right arm. The elongate body 102 is illustrated in a resting state, or initial position, in solid lines, and in a stretched state, or final position, in dashed lines.

[0043] It will be understood that the exercise shown in FIG. 3 can be performed by the left arm as well. For example, a user can hold one end 110A of the exercise device 101 in the user's left hand behind the user's head/neck and hold the other end 110B with the user's right hand behind the user's back. The user can then extend the user's left arm above the user's head to perform the exercise thereby stretching the elongate body 102. This exercise would appear as a mirror image of FIG. 2A if it were to be illustrated.

[0044] It will also be understood that in some embodiments, the length of the exercise device 101 can provide additional, optional benefits, for example but without limitation, some lengths of the exercise device 101 can allow a user to both wrap the device 101 once or twice around the user's arm and also perform a wide variety of exercises. It has been found that the length of 5-10 inches can provide the optional benefits of allowing some users having a typical arm diameter, to wrap the device 101 around their wrist once with its connection devices 106A, 106B connected to each other and also to perform certain convenient exercises such as the curling exercise illustrated in FIGS. 2A and 2B. Further, it has been found that the length of 11-21 can provide the optional benefits of allowing some users having a typical arm diameter, to wrap the device 101 around their wrist twice with the connection devices 106A, 106B connected to each other and also to perform certain convenient exercises such as the modified curling exercise described above and illustrated in

[0045] FIGS. 2A and 2B. It will further be understood that the potential exercises described (e.g., in FIGS. 2A, 2B, and 3) are merely examples of exercises that can be performed. There exist many other exercises that a user can perform with the exercise device that are illustrated or described herein. A user can use one or both hands/arms, one or more surfaces, and/or one or more feet/legs to perform a variety of exercises. For example, in one exercise, a user can hold both ends of the exercise device in the user's hands and the user can bend the user's knees and wrap the device around the base of the user's feet. The user can then extend the user's feet while holding the two ends of the exercise device to achieve resistance and perform an exercise for both legs. In another example, a user can step on both ends of the exercise device using the floor to hold the device in place and the user can bend the user's knees while keeping the user's back straight to grab the elongate body with one or both hands and pull it up by extending the knees.

[0046] It will further be understood that the above-noted dimensions are merely exemplary. The dimensions each depend upon one another, upon the overall dimensions of the device and strands and the desired elasticity of the device or strands. It is understood that one of ordinary skill in the art can readily vary the dimensions to adapt the exercise device for a particular application through routine experimentation or use, in view of the disclosure herein.
