This application claims priority to U.S. Provisional Patent Application Ser. No. 63/662,992, entitled “Resistance Band Cover Device,” filed Jun. 21, 2024. The contents of this application are hereby incorporated by reference in their entirety.

The fitness and wellness industry has witnessed significant growth over the past decade plus, with a notable rise in the use of resistance bands and related accessories. These devices offer a versatile, portable, and cost-effective means for strength training, physical therapy, and overall fitness. Despite their widespread adoption, there remains an industry landscape that contains opportunities for innovation and improvement, particularly in the areas of enhancing user experience and safety while using resistance bands. A gap identified within this market pertains to the limited adaptability and durability of current resistance band products. Many users find that the one-size-fits-all approach does not accommodate the varied thicknesses and lengths of resistance bands used across different exercises. Furthermore, the wear and tear from regular use can compromise the integrity of these bands, posing risks of snapping and potential injury to users. Additionally, the existing solutions often overlook the need for easy interchangeability and customization based on individual user requirements.

Specifically, one of the primary safety concerns associated with the use of elastic resistance bands lies in the potential for these bands to snap during use, posing significant risk to the user. Such incidents can occur due to overstretching, material degradation over time, or unnoticed wear and tear on the band. When a resistance band snaps, it can recoil with considerable force, potentially causing serious injuries to the user. These injuries might include welts, bruises, cuts, or even severe eye injuries if the band strikes the face or other sensitive areas. Furthermore, the sudden loss of resistance can cause the user to fall, leading to sprains, fractures, or other impact-related injuries. This hazard is particularly concerning in environments where users may not have immediate access to medical assistance, such as home gyms. The unpredictability of these incidents adds a layer of risk to resistance band exercises, underscoring the need for enhanced safety measures and durable, reliable equipment in resistance band workouts.

Moreover, reviewing existing accessories, such as band covers and handles, reveals a common shortfall in their design and functionality. These products frequently fail to address the essential needs for modularity, ease of use, and comprehensive protection of the bands. There also exists a need in the market for features that would enhance the utility and lifespan of resistance bands, including options for adjustable length and thickness, secure attachment mechanisms, and materials that minimize wear on the resistance band.

Given the existing problems with resistance band accessory products, such as limited customization options, potential safety hazards, lack of easily applying band covers, and insufficient durability, there is a clear need for a device that addresses these issues comprehensively. The industry requires a solution that not only extends the life of resistance bands but also improves the user-friendliness, safety and effectiveness of their resistance band workouts.

A device, such as the proposed resistance band cover device, may solve these problems by offering a modular design that allows for customization to fit various sizes and types of resistance bands. By incorporating features like adjustable-length band cover sections, interchangeable thickness adapters, and secure coupling mechanisms, this device aims to enhance user safety, extend the lifespan of resistance bands, and provide a more personalized and effective workout experience. Furthermore, the use of durable, non-elasticized materials for the band cover may reduce the risk of band wear and snapping, addressing a significant concern among users.

Before describing the present invention in detail, it is to be understood that the invention is not limited to any one of the particular embodiments, which of course may vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and therefore is not necessarily intended to be limiting. As used in this specification and the appended claims, terms in the singular and the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a resistance band cover device” or any of its constituent parts also includes a plurality of resistance band cover devices or any of its constituent parts and the like.

Exemplary embodiments of the present invention are illustrated in the accompanying figures. As shown in, a side elevational view of a resistance band cover devicein a fully coupled configuration relative a coupling claspdisposed at a terminal end of a resistance band is provided. The resistance band cover devicemay comprise an elongate band bodyhaving a coupling elementdisposed at a first terminal end of the body. The coupling elementmay comprise a first coupling memberand a second coupling memberthat extend from a coupling bodyas shown in. The coupling claspmay comprise an aperturedisposed therein.

In the fully coupled configuration, the first coupling membermay comprise a proximal portion that is disposed on a first side of the coupling claspand a distal portion that is disposed on a second side of the coupling claspsuch that the first coupling memberis disposed through the aperturein order to accomplish this arrangement. Accordingly, the first coupling membermay be oriented in a vertical manner relativeand in a parallel configuration with that of the orientation of the elongate band bodyas shown in. The second coupling membermay have its length disposed horizontally around a base of the coupling claspin a manner orthogonal to that of the first coupling member. Further, the first and second coupling members,may be disposed in an overlapping manner or an orthogonal overlapping manner as shown in.

The coupling clasp, equipped with the aperture, may be implemented as a handleat the end of the resistance band with the aperturedisposed through a central portion of the handle. In such an embodiment, the first and second coupling members,may be secured to a base of the handleand through the aperturein the handlein a similar manner to that of the coupling claspembodiment. Thereby, the coupling elementmay act as a modular means of coupling the elongate band bodyto the terminal ends of the resistance band no matter what is disposed at those terminal ends, whether that be a coupling clasp, a handle or the like.

As shown in, a side elevational view of a resistance band cover devicein a partially coupled configuration relative the coupling claspdisposed at a terminal end of a resistance band is provided. The resistance band cover devicemay be at least similar or the same as the resistance band cover deviceas illustrated and described with respect to. In the partially coupled configuration, the first coupling memberis disposed in the same position relative that which is illustrated inin the fully coupled configuration. However, the second coupling memberis illustrated as being in the partially coupled state where the memberis disposed on a side of the coupling claspthat is opposite that of the first coupling memberin a non-overlapping manner relative thereto as shown in. The first coupling memberstill remains in an overlapping manner relative the coupling body

As shown in, a side elevational view of a resistance band cover devicein an uncoupled configuration relative a coupling claspdisposed at a terminal end of a resistance band is provided. The resistance band cover devicemay be at least similar or the same as the resistance band cover deviceas illustrated and described with respect to. In the uncoupled configuration, the first coupling memberis removed from the apertureand disposed on the same side of the coupling claspas the second coupling member. Further, none of the first and second coupling members,and the coupling bodyare disposed in an overlapping orientation relative one another. The coupling bodyin the uncoupled configuration is disposed in a slack coupling arrangement around the base of the coupling claspsuch that the coupling claspmay be readily removed from the coupling bodythat is disposed therearound.

As shown in, a side elevational view of a threading elementof a resistance band cover devicein a coupled configuration relative a coupling claspdisposed at a terminal end of a resistance band is provided. The resistance band cover devicemay be disposed around the resistance band and coupled thereto at a base of the coupling clasp. The coupling claspmay further comprise a fixed body portionand a movable jaw portionwhich may move in one degree of freedom between an open state and a closed state.

In the open state, the threading elementmay be coupled through the apertureof the coupling clasp. Specifically, an elongate shaftof the threading elementmay comprise a U-shaped memberextending therefrom which allows the threading elementto couple to the coupling claspvia the apertureand movable jaw portion. In use, the threading elementmay be utilized in the coupled configuration to guide the resistance band through the interior cavity of the resistance band cover devicevia a user pulling the resistance band by the threading elementcoupled to the coupling clasp.

Utilizing the threading element, as described, to assist in guiding the resistance band through the interior cavity of the band cover deviceaddresses a significant challenge posed by the high coefficient of friction between the band and the band cover device. This friction can make the task of inserting or threading the band through the cover arduous and time-consuming, potentially deterring users from utilizing the cover consistently. The innovative design of the threading element, featuring a U-shaped memberextending from an elongate shaft, allows for a smooth and efficient coupling to the coupling claspvia the apertureand movable jaw portion.

This design not only simplifies the process of securing the band within the cover devicebut also significantly reduces the physical effort required from the user. By facilitating an easier insertion of the resistance band into the band cover device, users are more likely to utilize the cover regularly, thereby extending the lifespan of the resistance bands by protecting them from wear and tear and maintaining the safety and integrity of their workout equipment. Furthermore, this user-friendly feature enhances the overall user experience, making the resistance band cover devicemore accessible and appealing to a broader audience, including individuals with limited strength or dexterity.

As shown in, an overhead view of a threading elementof a resistance band cover device in an uncoupled configuration is provided. The threading elementmay comprise a first elongate shaft portionterminating at its distal end into an inflection jointwhich is the point at which the first elongate shaft portiontransitions into the second elongate shaft portion. The first and second elongate shaft portions,along with the inflection jointcollectively define an aperturetherein through which the fixed body portionof the coupling claspofmay be disposed.

As shown in, an overhead perspective view of a cover bodyof a resistance band cover devicein an uncoupled decompressed configuration relative a resistance bandalong with a cross-sectional view of a segmentof the resistance band cover deviceis provided. The resistance band cover devicemay comprise the resistance bandcoupled within the cover body. However, for purposes of illustration,illustrates the resistance bandseparate from the cover bodyand in an uncoupled configuration.

The resistance bandmay comprise an elastic band bodyterminating at either end into respective coupling clasps. The cover bodymay comprise an elongate band coverwhich is illustrated as being in a default relaxed state. In a stretched state, the elongate band covermay utilize a stretch-limiting elementin order to limit the degree to which the covermay stretch, thereby preventing the resistance bandcontained therein from over-stretching which degrades the structural integrity of the band. The elongate band covermay terminate at either end into respective coupling elements each comprising horizontal couplings,and vertical couplings,. The horizontal and vertical couplings,,,may couple to the coupling claspsin a manner as previously described with respect toof this disclosure.

The cover bodymay comprise a multilayer construction such that a cross-sectional view of a segmentof the cover bodyreveals an outer protective layer, an interior fabric layerand an inner low-friction coating layerall of which surround an inner cavitythrough which the elastic band bodyof the resistance bandmay be disposed when the bandand cover bodyare disposed in the coupled configuration. The uncoupled configuration may be utilized by the user when it is desired for the resistance band cover deviceto be modularly swapped out for another one for purposes of cleaning, aesthetics, or replacement. The coupled configuration may be utilized by the user when it is desired to use the cover devicearound the resistance bandduring routine exercise.

The multilayer construction of the cover body, featuring an outer protective layer, an interior fabric layer, and an inner low-friction coating layer, is advantageously designed to optimize both the durability and functionality of the resistance band cover device. The outer protective layermay be implemented using materials such as Cordura or canvas, known for their ruggedness and resistance to abrasions and tears, effectively shielding the underlying fabric layerfrom external damage and extending the cover's lifespan.

In addition to Cordura and canvas, the outer protective layerof the cover bodyin the resistance band cover devicemay utilize a variety of alternative materials to enhance the cover's resistance to wear and environmental factors. One suitable alternative is leather, known for its durability and aesthetic appeal, providing a robust barrier against mechanical damage while offering a classic look. Synthetic leather variants, such as polyurethane or PVC-based materials, may also be utilized for their similar appearance and enhanced resistance to water and stains, making them suitable for use in diverse environments.

For materials that can be deposited via spray coating, the inclusion of advanced polymeric coatings offers significant advantages. These may include polyurethane, acrylic, or silicone-based sprays, which provide a waterproof, flexible, and durable surface. These coatings are particularly beneficial as they can be applied uniformly over complex shapes, ensuring complete coverage and protection. Spray-on ceramics or ceramic-infused polymers are also viable options, offering exceptional hardness and resistance to abrasion, making them ideal for applications where extreme wear resistance is necessary.

Moreover, the use of high-performance elastomers like thermoplastic polyurethane (TPU) in a sprayable form can be particularly effective. TPU combines the flexibility of plastics with the elasticity of rubber, making it an excellent choice for protecting against both physical impacts and elongation stresses. The sprayed layer may form a seamless, elastic coating that conforms closely to the underlying fabric layer, enhancing the cover's overall integrity and resilience.

The interior fabric layer, serving as the main body of the cover, may be fabricated from durable, washable materials like polyester blends or duck cloth, offering a balance between strength and ease of maintenance. This layer ensures the cover remains in good condition through repeated uses and cleanings, maintaining the aesthetic appeal and hygiene of the fitness equipment.

The inner low-friction layermay be advantageous in minimizing the resistance encountered when sliding the cover over the elastic band body. This layer may be realized through advanced materials such as PTFE (Teflon) or silicone-based fabrics, which provide a slick, smooth surface to facilitate effortless insertion of the band and reduce friction during exercise, thereby preserving the integrity of both the band and the cover. Together, these layers may form a cohesive system that not only protects the resistance band but also enhances the user experience by simplifying the process of cover application and removal, making the resistance band system more accessible and enjoyable to use.

In some embodiments of, the multilayer construction of the cover body, featuring an outer protective layer, an interior fabric layer, and an inner low- friction coating layermay utilize one or more auxiliary layers,,,that are disposed adjacent first or second side surfaces of any of the layers,,as shown in. With respect to the following disclosure related toin the below paragraphs, any of the additional, additive, substitute, alternative, supplementary etc. layers described in these paragraphs may correspond to the one or more auxiliary layers,,,.

In some embodiments ofwith respect to layers-, the low-friction coating layermay be further optimized through advanced fabrication techniques or supplemented by additional sub-layers to reduce the friction between the elastic band bodyand the surrounding cover body. Frictional resistance between the inner surface of the cover and the band bodymay otherwise alter the effective resistance profile experienced during use and potentially increase the risk of strain or injury. To mitigate this, the layermay comprise or be combined with specialized materials or structures designed to minimize surface friction under dynamic loading conditions. Further, the inner low-friction layermay comprise a PTFE (polytetrafluoroethylene) film laminated to the interior fabric layerusing heat lamination or a compatible chemical adhesive. Alternatively, the PTFE may be applied as a sprayable coating and cured in place to form a continuous lubricating layer on the internal cavity-facing surface. Other options for layerinclude ultra-high molecular weight polyethylene (UHMWPE), which may be similarly adhered or coated to provide an exceptionally slick, durable surface.

In some embodiments ofwith respect to layers-, the inner low-friction coating layermay be implemented through a fabric structure that itself is composed of low-friction fibers. This woven or knitted fabric may be formed using PTFE yarns, high-grade Nylon, or UHMWPE fibers, allowing the friction-reducing characteristics to be inherently integrated throughout the layer structure. The layermay thus function both as a fabric and as a performance interface with the resistance band body.

In some embodiments ofwith respect to layers-, a discrete lubrication layer may be introduced between the elastic band bodyand the low-friction coating layer. This lubrication layer may be configured as a separate inner sleeve fabricated from silicone-infused textile, silicone rubber film, or flexible PTFE sheet material. The lubrication layer may either be fixed to the interior of layeror remain floating to permit localized sliding. This construction may further reduce frictional resistance, particularly under bending or high-speed elastic recoil conditions.

In some embodiments ofwith respect to layers-, a microtextured treatment may be applied to the interior surface of layerto further reduce friction through contact area minimization. This may be achieved through laser etching or chemical etching processes, producing a fine surface topology that allows air gaps or microscopic grooves to reduce drag between the surface and the elastic band. Additionally, dip-coating or spray-coating of a friction-reducing compound (e.g., silicone-based polymer or fluoropolymer blend) may be applied to form a thin, continuous low-friction interface layer atop layeror the lubrication layer.

In some embodiments ofwith respect to layers-, a multi-stage friction-reduction system may be employed, comprising a primary inner friction-reduction layer, an optional lubricating insert, and a microstructured or compound-coated sublayer. The sublayer may be located directly adjacent to layeror layered atop the insert, and may include durable, hydrophobic coatings with low surface energy to further minimize sticking or drag during use.

In some embodiments ofwith respect to layers-, each of the aforementioned inner-layer configurations may be selected or combined based on application-specific performance requirements such as user comfort, movement smoothness, ease of cover removal, and overall durability. These configurations allow the resistance band cover deviceto maintain alignment with the performance rating of the underlying resistance bandwithout inadvertently introducing additional resistance through frictional interference. This ensures a safer and more consistent user experience.

In some embodiments ofwith respect to layers-, in certain embodiments, the resistance band cover device may be configured with materials or treatments that impart anti-bacterial and/or moisture-wicking properties to enhance user hygiene during exercise. Such configurations may be particularly advantageous in high- use or shared environments, such as gyms, physical therapy clinics, or training studios, where moisture accumulation and microbial growth may otherwise pose hygiene and odor concerns.

In some embodiments ofwith respect to layers-, the cover body of the resistance band cover device may be formed from or include fabric materials inherently possessing moisture-wicking capabilities. These may include polyester, polypropylene, or engineered fabric blends designed to draw perspiration or moisture away from the user's skin or the elastic band body, allowing it to evaporate more efficiently at the outer surface. This may help maintain user comfort and reduce moisture saturation within the fabric layers of the device.

In some embodiments ofwith respect to layers-, the resistance band cover device may also incorporate materials that exhibit intrinsic anti-bacterial properties. For example, bamboo-based fabrics and merino wool may be utilized within one or more layers of the cover body to naturally inhibit the growth of odor-causing and potentially harmful bacteria. These materials may be selected not only for their hygienic performance but also for their softness and breathability, contributing to user comfort.

In some embodiments ofwith respect to layers-, in further embodiments, one or more fabric layers of the cover body may be chemically treated to provide active hygienic properties. For example, silver ion or copper ion treatments may be applied to the fabric surface or incorporated into the fiber structure itself. These ions exhibit bactericidal effects, preventing the accumulation of microbial agents on the surface of the cover device, especially after extended or repeated use.

In some embodiments ofwith respect to layers-, microencapsulation technology may also be used in the fabrication of the cover body. In such embodiments, microscopic capsules containing anti-bacterial agents may be embedded within the fibers of the fabric layer or deposited onto the inner or outer surfaces. These capsules may release their contents gradually over time or upon activation through heat, pressure, or moisture, thereby extending the hygienic efficacy of the cover device across multiple use and wash cycles.

In some embodiments ofwith respect to layers-, fabric weaving or knitting techniques may be employed to enhance the moisture management properties of the resistance band cover device. For instance, capillary or channel knitting techniques may create microchannels within the fabric matrix that actively guide moisture away from the interior cavity and toward the exterior of the cover for faster evaporation. These structural techniques may be used independently or in combination with hydrophobic coatings to further enhance performance.

In some embodiments ofwith respect to layers-, in certain embodiments, nanoparticles with anti-bacterial properties, such as silver or zinc oxide nanoparticles, may be embedded within the fabric fibers during manufacturing. These nanoparticles may provide a durable and continuous anti-microbial action across the life span of the device, resisting degradation during washing or heavy usage. This approach may be particularly advantageous for athletic or therapeutic environments with strict sanitation requirements.

In some embodiments ofwith respect to layers-, a dedicated moisture management lining layer may optionally be incorporated into the multilayer structure of the cover body. This lining may be positioned adjacent to the inner cavity or along the inner surface of the low-friction layer, and may comprise a hydrophilic or moisture-wicking textile engineered to pull moisture away from the elastic resistance band and out through the outer fabric layers. The integration of this lining may serve to regulate internal humidity and minimize slippage or discomfort during use.

With reference to, in relation to the dimensional proportionality between the thickness and length of the band cover, it is critically advantageous to establish a proportionality ratio that optimizes material flexibility while simultaneously preserving mechanical resilience. Specifically, maintaining the thickness of the band cover within a proportional range of 1:20 to 1:50 relative to its length is identified as optimal. This stipulated ratio facilitates enhanced durability and structural integrity, ensuring that the band can withstand routine stresses and strains without material fatigue or failure. Furthermore, adherence to this ratio guarantees that the band maintains a requisite degree of flexibility, thus providing ergonomic comfort and adaptability to the wearer's movements. This balanced approach not only extends the operational lifespan of the product but also enhances user satisfaction by maintaining comfort and functional reliability during use.

The dimensional proportionality between the thickness and length of the band cover is critically defined within a specified range from 1:20 to 1:50. Establishing a lower limit of 1:20 ensures adequate thickness relative to the length, which is essential for maintaining the structural integrity of the band. This minimum proportion is crucial as it imparts sufficient material strength to withstand regular usage stresses, effectively resisting tearing and maintaining form integrity under physical duress. Furthermore, a thickness at or above this ratio enhances wear resistance, offering protection against environmental degradation factors such as UV exposure, moisture, and mechanical abrasion. It also provides a tactile comfort that prevents the band from feeling overly insubstantial to the user, thereby improving the ergonomic experience.

Conversely, the upper limit of 1:50 is set to prevent excessive thickness, which can detrimentally affect the band cover's flexibility-essential for conforming comfortably to various strength tolerances and movements. Exceedingly thick bands can lead to a bulkier and heavier product, detracting from aesthetic appeal and user comfort due to increased weight. Moreover, thicknesses surpassing this ratio may result in inefficient use of materials, subsequently elevating production costs without corresponding benefits in durability or user comfort. Thus, adhering to this defined range optimizes the band cover's functional and ergonomic performance by balancing durability, flexibility, and cost-effectiveness, thereby ensuring that the product fulfills the varied demands of users without compromising quality or practical usability. More specific ranges, such as 1:20-1:30, 1:30-1:40, and 1:40-1:50, may be utilized in order to fine-tune the structural and performance characteristics desired in the band cover as described in the preceding related paragraphs.

With reference to, the structural implementation of the clasp on the band cover is designed to enhance both usability and durability, offering various configurations tailored to user preferences and functional requirements. Among the alternatives, the magnetic clasp, slide-and-lock mechanism, and traditional buckle present other distinctive mechanical advantages that cater to diverse user needs while still allowing for ease of connection and removal.

A magnetic clasp system utilizes a pair of aligned magnets integrated into the termini of the band cover. This design facilitates a seamless and user-friendly method for securing the band, allowing for quick attachment and detachment through magnetic attraction. The inherent simplicity of the magnetic clasp reduces the physical effort required to operate the band, enhancing the user experience especially for individuals seeking ease of use due to physical limitations or preference for quick access.

In contrast, the slide-and-lock mechanism comprises a slotted channel and a mating slider that locks into place, providing an adjustable and robust attachment solution. This mechanism is engineered to allow for precise adjustment of the band's length to accommodate different wrist sizes, thereby offering a customizable fit. The locking feature ensures that once adjusted, the band remains securely fastened, which provides reliability and security against accidental release during vigorous physical exercise activities.

A buckle-style element may be utilized which not only provides a secure fit but also allows for manual adjustment of the band's tightness, catering to user-specific comfort levels. The physical nature of the buckle's operation-inserting the pin through an appropriate hole in the band-offers tactile feedback that assures the user of a secure fastening, thereby enhancing the psychological comfort regarding the stability of the clasp.

With reference to, in the construction of the band cover and its associated subcomponents, an expanded selection of materials may be chosen to optimize both performance attributes and aesthetic qualities of the band cover. Silicone composites, woven textiles, and advanced polymers are among the primary materials considered due to their superior mechanical and physical properties that ensure high durability, exceptional flexibility, and robust resistance to various environmental stressors.

Silicone composites may be employed for their outstanding elasticity and thermal stability, making them ideal for applications requiring frequent flexing and exposure to varying temperatures. These composites also exhibit excellent chemical inertness and water repellence, enhancing the longevity of the band in humid or corrosive environments. The hypoallergenic nature of silicone further enhances user comfort by minimizing skin irritation. Woven textiles may be incorporated into the design for their texture and breathability, contributing to the overall comfort and wearability of the band. These materials provide a unique aesthetic appeal through varied patterns and colors, allowing for greater customization and style differentiation. Additionally, textiles can be treated with coatings to enhance their water and UV resistance, thus extending their usable life and maintaining their appearance under sun exposure. Advanced polymers may be selected for their ability to combine lightness with high tensile strength. Polymers such as polyurethane and high-density polyethylene are particularly valued for their moldability and abrasion resistance, which are critical for maintaining the structural integrity and visual appeal of the band cover under everyday wear conditions. The versatility of polymers also supports innovations in clasp and adjustment mechanisms, providing both functionality and sleek design.
