DETAILED DESCRIPTION

[0010] Conventional resistance training is limited to using heavy weights or resistance bands, which may pose several problems for individuals looking to improve their strength and physical health. These issues include the inability to lift heavy weights due to injuries or congenital conditions, the difficulty in finding suitable alternatives that provide adequate resistance without compromising safety, and the challenge of accurately measuring and adjusting resistance levels when using alternative methods like springs or bands.

[0011] One problem is that people may not be able to lift heavy weights due to various reasons, such as injuries like torn ligaments or congenital conditions like arthritis. This limitation may hinder their ability to engage in effective strength training exercises, which are crucial for maintaining muscle mass, bone density, and overall physical health. Another problem may be finding suitable alternatives to heavy weights that may provide adequate resistance for muscle development without compromising safety or comfort.

[0012] One potential solution is to replace heavy weights with other means of resistance, such as springs or bands. These alternatives may offer variable levels of resistance without the need for bulky or cumbersome weights, making them more accessible and convenient for home workouts or rehabilitation settings. However, another problem may be ensuring that these resistance components do not snag or cause injury to the user during exercise, as improper use or malfunctions may lead to accidents or setbacks in progress.

[0013] One potential problem with using alternative resistance methods is the difficulty in accurately measuring and adjusting the level of resistance. Unlike traditional weights, which have clearly labeled masses, springs, and bands, they may not provide a consistent or easily quantifiable level of resistance. This inconsistency may make it challenging for users to track their progress, set appropriate goals, or maintain proper form during exercises.

[0014] Resistance exoskeletons may offer a novel approach to addressing these challenges. By applying resistance directly to the muscles, rather than putting strain on joints or inflaming existing maladies, exoskeletons may provide a safer and more targeted form of strength training. The shell of the exoskeleton may contain resistance components, such as bands or springs, protecting the user from potential injury.

[0015] Resistance exoskeletons may also allow exercisers to engage in a full range of motion while being fully protected from the resistance bands. The resistance exoskeleton's design may limit the range of resistance away from the point of articulation, reducing the risk of injury or discomfort. This targeted resistance may help users focus on specific muscle groups without compromising their safety.

[0016] Furthermore, resistance exoskeletons may prevent injuries associated with handling resistance bands, which may become slippery or difficult to hold during exercise. By containing the resistance within the exoskeleton's structure, users may maintain a secure grip and proper form throughout their workout. This feature may be particularly beneficial for individuals with limited grip strength or those prone to hand injuries.

[0017] FIG. 1 illustrates a resistance exoskeleton 100 configured for a first exercise. For example, the resistance exoskeleton 100 may be configured for a bicep curl. The resistance exoskeleton 100 limits the range of resistance away from the point of articulation, reducing the risk of injury or discomfort. The resistance exoskeleton 100 may help users focus on specific muscle groups without compromising their safety.

[0018] The exerciser, sensitive to the problems associated with conventional resistance training and aware of the solutions provided by the resistance exoskeleton 100, begins by placing the shoulder rest 105 against her shoulder. She then positions the tricep rest 102 against her tricep and grabs the curl handle 104 with an underhand grip. To perform a bicep curl, the exerciser contracts her biceps brachii muscle, causing her forearm to flex and bring her hand towards her torso. As she completes the curl, the exerciser's forearm supinates, rotating the palm upward. Throughout the motion, the components of the resistance exoskeleton 100 help to support the motion, while also protecting the user. The shoulder rest 105, tricep rest 102, and curl handle 104 work together to keep the resistance exoskeleton 100 in contact with the exerciser's arm throughout the movement, ensuring proper alignment and support.

[0019] The resistance exoskeleton 100 pivots to maintain a supported and comfortable alignment with the exerciser's motion, made possible by the low-friction pivot points 110. The pivot points 110 may be implemented using various mechanical fastening systems that provide low-friction pivoting. Simple bushings made from materials like bronze, brass, or polymers such as polytetrafluoroethylene (PTFE) or nylon may be used. Bearings, including ball bearings made from chrome steel or stainless steel, needle bearings with cylindrical rollers, or sleeve bearings made from sintered bronze or plastic, are also suitable options. Products like flanged sleeve bearings, thrust bearings, or miniature ball bearings are readily available and may be incorporated into the design.

[0020] FIG. 2 illustrates another view resistance exoskeleton 100 configured for the first exercise. For example, the resistance exoskeleton 100 may be configured for a bicep curl. The resistance exoskeleton 100 may prevent injuries associated with handling resistance bands, which may become slippery or difficult to hold during exercise.

[0021] The tricep rest 102 protects the exerciser's arm from a resistance band roller 111. Resistance bands 112 comprise various forms of resistance, such as springs, belts, elastic bands, or other mechanical systems. Springs may be made from materials like music wire, stainless steel, or titanium, while elastic bands are commonly made from natural rubber, thermoplastic elastomers (TPE), or synthetic rubber. Hydraulic or pneumatic systems designed for lightweight and portable applications may incorporate components made from aluminum, reinforced plastics, or composite materials.

[0022] The body of the resistance exoskeleton 100, which includes the forearm rest 101, may be formed from a variety of materials. Molded plastics like nylon, Acrylonitrile Butadiene Styrene (ABS), or polycarbonate are suitable options, as well as forged or pressed light metals such as aluminum or titanium. Cast resin and composite materials like carbon fiber may also be used for the body of the resistance exoskeleton 100. The shoulder rest 105, support arm 103, and thumb screws 109 create an adjustable system that allows for a variety of exercises, including curls, rows, extensions, lateral raises, and front raises. The support arm 103 may be made from rigid materials like cast metal, aluminum, or high-strength plastics, while the shoulder rest 105 is designed to be soft and comfortable. The thumb screws 109 enable the exerciser to adjust the position of the shoulder rest 105 relative to the support arm 103, either keeping it fixed or allowing it to change position during the exercise. This adjustability accommodates different exercises and user preferences.

[0023] The support arm 103 is affixed to the body of the resistance exoskeleton 100 via the support arm pins 107. This modular design allows for the use of alternative components to the support arm 103, making the resistance exoskeleton 100 adjustable and suitable for a variety of exercises. The pins may be made from materials such as stainless steel, aluminum, or high-strength plastics. Various coupling mechanisms, such as snap-fit connectors, bayonet mounts, or threaded fasteners, may be used to affix the support arm 103 to the body of the resistance exoskeleton 100. Strong fixation is essential to withstand the wide range of resistance and motion during exercises.

[0024] Foam padding 106 lines the body of the forearm rest 101, enhancing comfort for the exerciser. Suitable foam materials for exercise equipment include closed-cell Ethylene Vinyl Acetate (EVA) foam, open-cell polyurethane foam, memory foam, and high-density foam. The foam padding 106 may be bonded to the forearm rest 102 using adhesives like contact cement, double-sided tape, or hook-and-loop fasteners, as well as through compression fitting or overmolding techniques.

[0025] The quick-release locking pins 108 make the curl handle 104 part of a modular system, allowing it to be swapped out for different handles to accommodate various exercises. For example, the curl handle 104 may be replaced by a pull rope to challenge the user and encourage the formation of a stronger grip. Other handles may similarly encourage different grips: a neutral grip, wide grip, or close grip, which may be employed for other upper body exercises like rows, shoulder presses, or tricep extensions. This modularity enables the resistance exoskeleton 100 to adapt to the specific needs and preferences of the exerciser. In addition, quick-release locking pins 108 further allow the exerciser to adjust the position of the curl handle 104, such that exercisers with different-sized arms, hands, or comfort with grip distance may use the resistance exoskeleton. The quick-release locking pins 108 further enable the configuration of a system of embodiments, for the resistance exoskeleton, accommodating a wide range of exercises.

[0026] The resistance band roller 111 keeps the exerciser protected from the resistance band 112 by providing a physical barrier and a smooth, low-friction surface for the resistance band 112 to glide over during the exercise. This separation prevents the resistance band 112 from directly contacting the exerciser's skin, which may cause discomfort, irritation, or even injury, especially if the resistance band 112 were to snap or break during use. The resistance band roller 111 is designed to withstand the tension and movement of the resistance band 112, ensuring that the exerciser remains safe and protected throughout the workout.

[0027] In one embodiment, a channel or groove 120 formed into the forearm rest 101 may keep the resistance band 112 separated from the exerciser while not inhibiting the pivoting function of the low-friction pivot points 110. The channel 120 may be deep enough to accommodate the resistance band 112 and prevent it from slipping out, but shallow enough to allow the forearm rest 101 to pivot freely. The channel 120 may be lined with a low-friction material, such as PTFE or Ultra-High Molecular Weight (UHMW) polyethylene, to minimize wear on the resistance band 112 and ensure smooth operation.

[0028] In another embodiment, a series of small rollers or bearings embedded in the forearm rest 101 may create a low-friction pathway for the resistance band 112 to follow. These rollers may be positioned in such a way that they do not interfere with the pivoting motion of the Forearm Rest, while still keeping the resistance band 112 securely in place. The rollers may be made from materials like stainless steel, ceramic, or high-strength plastic, depending on the desired level of durability and performance.

[0029] In another embodiment, a flexible, low-friction lining or insert within the forearm rest 101 may create a dedicated space for the resistance band 112. The lining may be made from a material that may withstand the friction and tension of the resistance band 112, such as a reinforced polymer or a metal alloy with a low-friction coating. The lining may be shaped to allow the forearm rest 101 to pivot freely while still keeping the resistance band 112 contained and separated from the exerciser.

[0030] In another embodiment, a series of small, spring-loaded guides or pins within the forearm rest 101 actively keep the resistance band 112 in place. These guides may apply gentle pressure to the resistance band 112, preventing it from slipping out of position, while still allowing the forearm rest 101 to pivot smoothly. The springs may be made from materials like stainless steel or titanium, and the guides themselves may be made from a wear-resistant material like ceramic or hardened steel.

[0031] In another embodiment, a combination of the above mechanisms may be employed, such as a low-friction channel with spring-loaded guides or with small rollers. By combining multiple methods of separating and securing the resistance band 112, the forearm rest 101 may provide an even greater level of safety and performance, while still allowing for smooth, unrestricted pivoting motion through the low-friction pivot points 110. The specific combination of mechanisms may depend on factors such as the desired level of adjustability, the expected force and tension of the resistance band 112, and the overall design and materials of the resistance exoskeleton 100.

[0032] The support arm adjustment points 113 offer a versatile and customizable solution for adapting the resistance exoskeleton to various exercises and user preferences. Similar to the quick-release locking pins 108, which allow for the attachment of different handles for various exercises, the support arm adjustment points 113 enable the exerciser to modify the position and orientation of the support arm 103 relative to the tricep rest 102. This adjustability is helpful to accommodate different arm lengths, ensuring proper alignment and optimizing comfort during a wide range of movements. The support arm adjustment points 113 may be designed with a series of pre-drilled holes or a sliding track mechanism, allowing the exerciser to select the ideal position for their specific needs. Additionally, the adjustment points may incorporate a locking mechanism, such as a spring-loaded pin or a cam lever, to securely hold the support arm 103 in place during use.

[0033] Moreover, the support arm adjustment points 113 may be engineered to work in conjunction with the support arm pins 107, creating a modular and interchangeable system for attaching various The support arm 103 designs to the resistance exoskeleton. This modularity may enable exercisers to swap out support arms 103 with different lengths, angles, or materials to suit their specific training goals or rehabilitation needs. For example, a longer support arm 103 may be used for exercises that require a greater range of motion, while a shorter support arm 103 may be employed for more targeted, isolated movements. The support arm adjustment points 113 and support arm pins 107 may be designed with a universal attachment system, such as a threaded connection or a snap-fit mechanism, ensuring compatibility across a wide range of support arm 103 options. This interchangeable nature of the support arm adjustment points 113 and support arm pins 107 may greatly enhance the versatility and adaptability of the resistance exoskeleton, making it a valuable tool for a diverse array of users and applications.

[0034] FIG. 3 illustrates a resistance exoskeleton 200 configured for a first exercise. For example, the resistance exoskeleton 200 may be configured for a bicep curl. The resistance exoskeleton 100 limits the range of resistance away from the point of articulation, reducing the risk of injury or discomfort. The resistance exoskeleton 200 may help users focus on specific muscle groups without compromising their safety.

[0035] The resistance exoskeleton 200 includes a forearm rest 201, a tricep rest 202, a curl handle 204, and a shoulder rest 205. The shoulder rest 205, the tricep rest 202, and the curl handle 204 work together to keep the resistance exoskeleton 200 in contact with the exerciser's arm throughout the movement, ensuring proper alignment and support. The shoulder rest 205 may be coupled to the tricep rest 202 by a support arm 203. The shoulder rest 205, support arm 203, and thumb screws 209 create an adjustable system that allows for a variety of exercises, including curls, rows, extensions, lateral raises, and front raises. The thumb screws 209 enable the exerciser to adjust the position of the shoulder rest 205 relative to the support arm 203, either keeping it fixed or allowing it to change position during the exercise. This adjustability accommodates different exercises and user preferences.

[0036] The support arm 203 is affixed to the body of the resistance exoskeleton 200 via the support arm pins 207. This modular design allows for the use of alternative components to the support arm 203, making the resistance exoskeleton 200 adjustable and suitable for a variety of exercises. The pins may be made from materials such as stainless steel, aluminum, or high-strength plastics. Various coupling mechanisms, such as snap-fit connectors, bayonet mounts, or threaded fasteners, may be used to affix the support arm 203 to the body of the resistance exoskeleton 200. Strong fixation is essential to withstand the wide range of resistance and motion during exercises.

[0037] The body of the resistance exoskeleton 200, which includes the forearm rest 201, may be formed from a variety of materials. Molded plastics like nylon, ABS, or polycarbonate are suitable options, as well as forged or pressed light metals such as aluminum or titanium. Cast resin and composite materials like carbon fiber may also be used for the body of the resistance exoskeleton 200. The support arm 203 may be made from rigid materials like cast metal, aluminum, or high-strength plastics, while the shoulder rest 205 is designed to be soft and comfortable.

[0038] The resistance exoskeleton 200 pivots to maintain a supported and comfortable alignment with the exerciser's motion, made possible by the low-friction pivot points 210. The pivot points 210 may be implemented using various mechanical fastening systems that provide low-friction pivoting. Simple bushings made from materials like bronze, brass, or polymers such as polytetrafluoroethylene (PTFE) or nylon may be used. Bearings, including ball bearings made from chrome steel or stainless steel, needle bearings with cylindrical rollers, or sleeve bearings made from sintered bronze or plastic, are also suitable options. Products like flanged sleeve bearings, thrust bearings, or miniature ball bearings are readily available and may be incorporated into the design.

[0039] In embodiments, foam padding may be coupled to one or more components of the resistance exoskeleton 200 that may contact a user's body, enhancing comfort for the exerciser. Suitable foam materials for exercise equipment include closed-cell EVA foam, open-cell polyurethane foam, memory foam, and high-density foam. The foam padding may be bonded to components of the resistance exoskeleton 200 with adhesives like contact cement, double-sided tape, or hook-and-loop fasteners, as well as through compression fitting or overmolding techniques.

[0040] FIG. 4 illustrates another view resistance exoskeleton 200 configured for the first exercise. For example, the resistance exoskeleton 200 may be configured for a bicep curl. The resistance exoskeleton 200 may prevent injuries associated with handling resistance bands, which may become slippery or difficult to hold during exercise.

[0041] The curl handle 204 may be coupled to the forearm rest 201 by an adjustment mechanism 220. The adjustment mechanism 220 includes a bracket 222 and a locking pin 224. The bracket 222 is slidably coupled to grooves 226 formed in the forearm rest 201. The forearm rest 201 also includes a positioning channel 228. The positioning channel 228 includes a series of preformed locations at which the locking pin 224 can be engaged. As such, the locking pin 224 can be actuated to move the curl handle 204 relative to the forearm rest 201. Additionally, the locking pin 224 can be actuated to remove the curl handle 204 from the forearm rest 201. The adjustment mechanism 220 makes the curl handle 204 part of a modular system, allowing it to be swapped out for different handles to accommodate various exercises. For example, the curl handle 204 may be replaced by a pull rope to challenge the user and encourage the formation of a stronger grip. Other handles may similarly encourage different grips: a neutral grip, wide grip, or close grip, which may be employed for other upper body exercises like rows, shoulder presses, or tricep extensions. This modularity enables the resistance exoskeleton 200 to adapt to the specific needs and preferences of the exerciser. In addition, the adjustment mechanism 220 further allows the exerciser to adjust the position of the curl handle 204, such that exercisers with different-sized arms, hands, or comfort with grip distance may use the resistance exoskeleton. The adjustment mechanism 220 further enables the configuration of a system of embodiments for the resistance exoskeleton, accommodating a wide range of exercises.

[0042] Resistance band 212 may be coupled to the arm forearm rest 201 at L-shaped grooves 230, and coupled to the tricep rest 202 at L-shaped grooves 232. The resistance band 212 is held in the L-shaped grooves 230 and the L-shaped grooves 232 by the tension provided by the resistance band 212. The resistance band 212 may be positioned with a channel or groove 240 formed into the forearm rest 201 and tricep rest 202. The channel 240 may keep the resistance band 212 separated from the exerciser while not inhibiting the pivoting function of the low-friction pivot points 210. The channel 240 may be deep enough to accommodate the resistance band 212 and prevent it from slipping out, but shallow enough to allow the forearm rest 201 to pivot freely. The channel 240 may be lined with a low-friction material, such as PTFE or UHMW polyethylene, to minimize wear on the resistance band 212 and ensure smooth operation.

[0043] In some embodiments, the resistance band 212 may include various forms of resistance, such as springs, belts, elastic bands, or other mechanical systems. Springs may be made from materials like music wire, stainless steel, or titanium, while elastic bands are commonly made from natural rubber, TPE, or synthetic rubber.

The specific combination of mechanisms may depend on factors such as the desired level of adjustability, the expected force and tension of the resistance band 212, and the overall design and materials of the resistance exoskeleton 200.

[0048] In some embodiments, the resistance exoskeleton 200 may include support arm adjustment points as described above with reference to resistance exoskeleton 200 to allow attachment of different handles. This adjustability is helpful to accommodate different arm lengths, ensuring proper alignment and optimizing comfort during a wide range of movements. The support arm adjustment points may be designed with a series of pre-drilled holes or a sliding track mechanism, allowing the exerciser to select the ideal position for their specific needs.

[0049] FIG. 5 illustrates another resistance exoskeleton 300 configured for a fly exercise, according to an embodiment. The resistance exoskeleton 300 limits the range of resistance away from the point of articulation, reducing the risk of injury or discomfort. The resistance exoskeleton 300 may help users focus on specific muscle groups without compromising their safety.

[0050] The exerciser, seeking to target their chest muscles, particularly the pectoralis major, grips the fly handle 304 and the alternate fly handle 305, which are mounted on opposite sides of the resistance exoskeleton body 301. To perform a pectoral fly, the exerciser starts with their arms extended out to the sides, holding the handles, and then brings their arms together in front of their chest, contracting the pectoral muscles. The resistance is provided by the resistance band 312, which is secured to the resistance exoskeleton body 301 using the quick-release locking pins 308.

[0051] The fly arm 303 provides the necessary distance between the handles and the resistance exoskeleton body 301, allowing for a full range of motion during the fly exercise. The fly arm 303 is securely attached to the resistance exoskeleton body 301 using the support arm pins 307, ensuring stability and safety during use. The low-friction pivot points 310 enable smooth rotation of the fly arm 303 during the exercise, minimizing any unnecessary strain on the exerciser's joints.

[0052] The resistance band roller 311 acts as a pivot point for the resistance band 312, helping to reduce friction and wear on the band during the fly motion. This feature ensures that the resistance remains consistent and smooth throughout the exercise, allowing the exerciser to focus on proper form and muscle engagement. The resistance band 312 itself is a high-strength rubber band with built-in hooks on each end, making it easy to swap out for different resistance levels depending on the exerciser's preference and fitness level.

[0053] By gripping the fly handle 304 and the alternate fly handle 305, the exerciser may use the resistance exoskeleton 300 to effectively target their chest muscles without the need to wear the device on their arm. This versatility allows for a more diverse range of exercises and makes the resistance exoskeleton 300 accessible to a wider group of users, including those who may have limitations that prevent them from wearing the device in the traditional manner. The modular nature of the resistance exoskeleton 300, with its interchangeable handles and adjustable resistance, ensures that it may be easily adapted to suit various exercises and user preferences, making it a valuable tool for both strength training and rehabilitation purposes.

[0054] The modular design of the resistance exoskeletons 100, 200, and 300 enables them to be used for a wide range of exercises, both as an exoskeleton device and as a standalone resistance training tool. The quick-release locking pins 108/208, adjustment mechanism 220, and the support arm pins 107/207/307 allow for easy attachment and removal of various components, such as the curl fandle 104 for bicep curls or the fly handle 204 and alternate fly handle 205 for fly exercises. This modularity ensures that the resistance exoskeletons 100, 200, and 300 may be quickly adapted to target different muscle groups and accommodate various exercise preferences. By offering both exoskeleton and non-exoskeleton applications, the resistance exoskeletons 100, 200, and 300 provide a comprehensive and versatile solution for strength training and rehabilitation, catering to the diverse needs of exercisers and fitness enthusiasts alike.

[0055] FIG. 6 illustrates the resistance exoskeleton 400 configured for a hammer curl exercise, highlighting its versatility in targeting different muscle groups and accommodating various joint movements. The resistance exoskeleton 400 limits the range of resistance away from the point of articulation, reducing the risk of injury or discomfort. The resistance exoskeleton 400 may help users focus on specific muscle groups without compromising their safety.

[0056] The exerciser, equipped with the resistance exoskeleton 400, begins by placing the shoulder rest 405 on top of their shoulder, ensuring a comfortable and secure fit. The tricep rest 402, designed specifically for hammer curls, is then positioned against the outer side of the exerciser's tricep, while the hammer curl forearm rest 401 rests against the narrow side of the forearm.

[0057] To perform a hammer curl, the exerciser grasps the hammer curl handle 404, which is mounted to the hammer curl forearm rest 401, using a neutral grip with their palm facing inward. The exerciser then contracts their biceps brachii and brachialis muscles, causing their forearm to flex and bring their hand towards their shoulder. Throughout the movement, the shoulder rest 405, hammer curl tricep rest 402, and hammer curl handle 404 work in unison to maintain proper alignment and support, ensuring that the resistance exoskeleton 400 remains in constant contact with the exerciser's arm.

[0058] The support arm 403, which connects the tricep rest 402 to the shoulder rest 405, may be positioned on either side of the resistance exoskeleton 400, allowing for ambidextrous use and accommodating the exerciser's preferred arm. The support arm 403 is securely fastened to the tricep rest 402 using the support arm pins 407, while the thumb screws 409 enable the exerciser to adjust the position of the shoulder rest 405 relative to the support arm 403, ensuring a customized and comfortable fit.

[0059] Foam padding 406 covers the hammer curl forearm rest 401, hammer curl tricep rest 402, and shoulder rest 405, providing a soft and comfortable interface between the exerciser's arm and the resistance exoskeleton. The low-friction pivot points 410 facilitate smooth rotation between the hammer curl forearm rest 401 and the hammer curl tricep rest 402, minimizing any unnecessary strain on the exerciser's elbow joint during the hammer curl motion.

[0060] The quick-release locking pins 408 securely attach the hammer curl handle 404 and the resistance bands (not shown) to both the hammer curl tricep rest 402 and the hammer curl forearm rest 401. This feature allows for quick and easy interchangeability of handles and resistance levels, enabling the exerciser to customize their workout according to their specific needs and preferences.

[0061] The hammer curl configuration of the resistance exoskeleton 400 demonstrates its adaptability in targeting different hinge joints throughout the body. By modifying the shape and orientation of the forearm rest, tricep rest, and handle, the resistance exoskeleton 400 may be easily adjusted to provide resistance for exercises targeting the knees, elbows, or other hinge joints. This versatility makes the resistance exoskeleton 400 a valuable tool for a wide range of strength training and rehabilitation applications, catering to the diverse needs of exercisers and fitness enthusiasts alike. Moreover, any of the components of the resistance exoskeleton 100, the resistance exoskeleton 200, the resistance exoskeleton 300, and the resistance exoskeleton 400 may be interchanged.
