No. 63/329,395, filed on 4/9/2022, and U.S. provisional patent application Ser. No. 63/426,409, filed on 11/18/2022, all of which are incorporated herein by reference in their entirety.

Technical Field

The present invention relates generally to strength training and exercise equipment.

Background

Strength training and exercise equipment is useful for maintaining personal fitness and good health. Strength training and exercise equipment in the prior art includes dumbbell, barbell, exercise bench, squat frames, weight lifts, treadmills, stair climbs, stationary bicycles, tensile cords, resistance bands, exercise bands and vests, TRX systems, and the like. Strength training and exercise equipment is useful and popular in fitness centers, physical therapy centers, and homes. Although they are popular, fitness centers and physical therapy centers have drawbacks including internal operating costs, membership, and user expense, as well as the need for large space for setting up large, heavy, and immobile pieces of equipment. Furthermore, users must travel to fitness and physical therapy centers, which can be time consuming and logistically challenging for some users, including those who need assistance or use mobile devices such as walkers and wheelchairs.

Strength training and exercise equipment in homes, such as residential homes and apartment buildings, offer several advantages, including convenient home use, the ability of the user to choose which equipment to purchase and install at home, and lower costs compared to fitness center members and physiotherapy fees. However, home strength training and exercise devices are typically large, heavy, and not mobile, and users are often limited by limited space and budget.

In order to address the shortcomings of the strength training and exercise devices described above, as well as the shortcomings of using such devices in fitness centers, physiotherapy centers, and homes, there is a need for a device that is inexpensive, lightweight, small in footprint, easy to use indoors or outdoors, and that enables a user to perform a variety of strength training exercises with a variety of levels of exertion, in a variety of upright, seated, or horizontal positions, and while stationary or in motion. The prior art attempts to design equipment that attempts to achieve some of these advantages, but is deficient in many respects, including various wearable exercise bands, vests, suits, and the like. See, for example, U.S. patent 5372565, 5813955, 6691318, 7707652, 7998041, 8443465, 8968166, and 9724554, and U.S. patent publications US20030125170A1, US20050282689A1, US20060040805A1, US20070015640A1, and US20070219074A1. These prior art attempts to design devices to achieve these advantages have not proven useful or successful. Drawbacks appear to include limited functionality and practicality, complexity of design, and awkwardness to use.

To address the limitations of strength training and exercise devices described above, the present inventors have developed a new exercise device system and associated method of use. The devices developed by the inventors and described in detail below include a piece of simple, lightweight, easy-to-use wearable equipment and associated accessories that enable a user to perform a wide variety of strength training exercises without the equipment typically found in a fitness center or physical therapy center. The apparatus described herein includes a wearable vest with strategically located connection points, such as loops or rings, for attaching tensile cords of different lengths. The ends of the tensile cord have connectors such as snap clips (carabinerclip) that can be hooked on to connection points on the vest at one end of the cord and attached to loops on handles, rods, arm straps, leg straps, foot straps, etc. at the other end of the cord for engaging the user's hands and feet. The connection points on the back are strategically placed to enable various strength training exercises to be performed as the user pulls or pushes on the ends of the tensile cord. In addition, the vest is adjustable to achieve a comfortable, non-slip fit on the user. Additional features include pockets on the back for holding weight bags or inserts, or for storing tensile cords, water bottles, etc. A detachable backpack, as well as other accessories and features, is shown in the drawings and discussed in the following detailed description.

In one presently preferred embodiment, the rigid substrate 320 is an Acrylonitrile Butadiene Styrene (ABS) plastic sheet that can be thermoformed to a desired profile, and the compliant portion 324 is a closed cell foam. Portions 320 and 324 of the composite are joined by an adhesive film layer. Other materials are contemplated for the front support member 300, such as metal or other thermoplastic materials for the rigid base portion 320. Further, the compliant portion 324 of the front support member 300 may be formed of cloth, padding, fabric, or open cell foam. In one form, the front support member 300 may have a plurality of through holes or apertures 328 to reduce its weight and improve breathability. The corners of the front support member 300 are curved to improve the comfort of the user and to ease insertion into the vest 1.

In one presently preferred form of the invention, each front support member 300 includes a top end 302 of about 3.75 inches (95 mm), a bottom end 304 of about 3.25 inches (83 mm), and an overall height of about 9 inches (229 mm). Preferably, compliant portion 324 has a thickness of about 1/8 inch (3.2 mm).

Referring to fig. 44-47, a wrist or forearm liner attachment 350 is shown for wrapping around the forearm or wrist of a user. Forearm liner 350 is advantageous for users of the invention who cannot grasp handles attached to a tensile cord (e.g., 40 in fig. 5-7), such as amputees, stroke victims, arthritis, and other disabled or diseased conditions. The forearm liner 350 may have one or more connection points or loops at various locations for engagement with the tensile cord 40 extending from the vest to the forearm liner 350. Preferably, there are two rings 351 located near the top and bottom ends on the left side of the liner 350, two rings 352 located near the top and bottom ends on the right side of the liner 350, and two rings 353 located near the top and bottom ends on the middle of the liner 350. The bushing 350 may have one or more cinching straps, bands, velcro straps, or other similar connectors to tightly and securely hold the bushing 350 around the arm. Available choices of design, construction, and materials for the bushing 350 are known to those of ordinary skill in the art. The bushing 350 preferably has two cinching straps 354 that are secured with velcro to secure the bushing 350 around the forearm of the user.

Referring to fig. 48-51, a knee bushing accessory 360 for wrapping around the knee of a user is shown. The knee liner 360 is advantageous for users of the present invention who are not able to use foot straps (e.g., 70 in fig. 9a and 9 b), such as amputees, diabetes, arthritis, and users with other disabilities or disorders. The knee liner 360 may have one or more connection points or loops at various locations for engagement with the tensile cord 40 extending from the vest 1 to the knee liner 360. Preferably, there are two rings 361 located near the top and bottom ends on the right side of the knee bushing 360, two rings 362 located near the top and bottom ends on the left side of the knee bushing 360, and two rings 363 located near the top and bottom ends on the middle of the knee bushing 360. The knee brace 360 may have one or more cinching straps 370, bands, velcro straps, or other similar connectors to snugly and securely hold the brace 350 around the leg adjacent the user's knee. Available choices of design, construction, and materials for bushing 360 are known to those of ordinary skill in the art. The knee bushing 360 preferably has a front aperture 372 and a rear aperture 374 to accommodate bending of the knee during use of the bushing 360.

Referring now to fig. 52-57, the inventors have discovered that the connection of multiple tensile cords extending from the same accessory (e.g., handle 44, foot strap 70, wrist strap 350, knee strap 360, etc.) to different attachment points or loops 8a-8j on the vest 1 can provide novel exercises for multiple muscle groups during the range of motion of the user. The cords may have different lengths and strength resistance to vary the degree of resistance and range of motion provided by the tensile cord during use. Fig. 52 shows a configuration of the vest 1 in which the handles 44 are attached to the loops 8d and 8h by two different ropes and have increased resistance compared to using a single rope connected to a single loop and also provide additional resistance in a greater range of motion in both the upward and downward directions as the user moves his or her arm up and down. Fig. 53 shows the construction of the vest 1 in which the handles 44 are attached to the loops 8e and 8f by two different ropes for increasing the bending of the arms of the resistance and also shows the foot straps 70 attached to the loops 8b and 8c by two different ropes for increasing the leg extension or squat movement of the resistance. In comparison, fig. 54 shows a pair of foot straps 70 attached at different points 72 and 73 to a rope connected to a lower loop on the vest 1 for different resistance-increasing leg extension or squat exercises. Fig. 55 shows the use of two rear loops 8i and 8j to connect a pair of ropes to a pair of knee bushings 360 and a pair of foot straps 70 for allowing resistance to any calf movement of the user. Fig. 56 shows the user wearing a forearm liner 350 connected to both side rings 8d and 8d for hands-free resistance to all arm movements. Figure 57 shows a combined exercise using the forearm liner 350 and handle 44, wherein three separate loops 8g, 8a, 8b are used on the vest 1. It will be apparent to those skilled in the art that a variety of other multi-point exercises can be performed using the vest 1 and one or more accessories.

The exercise systems and methods of use of the vest 1 and accessories disclosed herein include donning and wearing a user of the vest 1. The user selects the length of the tensile cord, the resistance strength of the tensile cord, and whether to double the tensile cord to increase the resistance, depending on the exercise to be performed. For example, for exercises using a connection with shoulder rings 8g and 8h or lower rings 8c and 8f on the back center, the user may select a tensile cord 50 having an unstressed or resting length in the range of about four inches (102 mm) to about fourteen inches (355 mm) to perform an arm exercise in which the arm is straightened. In a preferred embodiment, a rope of approximately eight inches (203 mm) in length is used. For example, see fig. 17a, 17g, 17i, 17j, 17o and 17p, wherein shorter ropes may be preferred, and see fig. 17e, 17k, 17l and 17m, wherein medium length ropes may be used. Shorter cords, such as six inch (152 mm) cords, seven inch (178 mm) cords, eight inch (203 mm) or nine inch (229 mm) cords, are preferred for exercises requiring less stretch, such as shoulder presses, chest presses, etc. To perform bicep curls, the user may select a shorter cord, i.e., a tensile cord having a length of about six inches (152 mm), seven inches (178 mm), or eight inches (203 mm), and attach it to the lower front loop on the back. For exercises using the foot bar 75 or foot strap 70, the user may select a longer tensile cord having a length in the range of about sixteen inches (406 mm) to twenty-eight inches (711 mm). In a preferred embodiment, a length of eighteen inches (457 mm) is used. See, for example, the exercises shown in fig. 17b, 17c, 17f, 17h and 17 n. For exercises using thigh straps, such as kneeling hydrant exercises or clamshell exercises, the user may choose a shorter tensile cord in the range of eight inches (203 mm) to fourteen inches (355 mm). The optimal length of the tensile cord may depend on the size of the user and the length of his or her limb.

After selecting the stretch cord, the user may then select any combination of handles (see selections in fig. 6, 7a and 8), foot straps (see selections in fig. 9a and 9 b), bars (see selections in fig. 10-13), thigh straps (see fig. 14), forearm straps (see fig. 44-47) and knee straps (see fig. 48-51), depending on the exercise to be performed. The user may then perform the exercise. Various combinations of vests, stretch cords, foot straps, thigh straps, knee straps, handles and bars enable the user to select from among the various exercises described above and shown in fig. 17 a-17 p, as well as many other exercises not shown.

The exercise devices and systems disclosed above and associated methods of use enable a user to perform a wide variety of exercises without the need for the extensive equipment typically found in fitness centers, rehabilitation centers, homes, and the like. The disclosed system advantageously uses the human body as an anchor for stretch-cord exercise, wherein the ends of the stretch-cord do not need to be attached to an external anchor. Such exercise devices and related systems, as well as many related methods and exercises, do not use gravity and may be used and performed in a weightless environment. Using the disclosed vest, device and stretch cord system, the vest can be worn, the device can be used, and exercises can be performed while sitting, standing, lying, walking or running indoors or outdoors, and while stationary or moving. The disclosed system is useful for persons with impaired strength or mobility, including wheelchair-bound persons performing many strength training exercises. Thigh strap, forearm strap, and knee strap embodiments are useful for performing various strength training exercises for amputees of hands, feet, or lower legs. Unlike carrying and using weights (e.g., dumbbell) while walking or running, the disclosed system is capable of combining resistance training (e.g., arm exercises using a vest and tensile cords) while walking or running at the same time, without the lower limbs bearing significant weight. Since the sets of tensile cords are fairly light, they can be carried in storage pockets during stationary or athletic exercises (e.g., while walking or running). At any time during exercise, the selection and configuration of the tensile cord may be changed to increase or decrease resistance on the handle while stationary or in motion. Thus, the present invention achieves a dynamic and progressive resistance training usage when moving along a path and in combination with heart training.

For example, in the method of use implemented by the present invention, the user may gradually change the resistance on the tensile cord during the exercise session by changing the tensile cord to a different weight (different weights meaning different levels of tensile resistance, typically measured in pounds or kilograms) or by increasing or decreasing the number of tensile cords attached to the handle or harness in order to multiply or decrease the amount of force required to stretch the cord. In an alternative aspect and benefit of the method of use achieved by the present invention, by varying the connection points on the vest, handle and belt, the user can change the direction of movement of the hands, arms, legs and/or feet during the exercise process to engage different muscles required to move the handle and/or belt. Thus, in an alternative aspect and benefit of the method of use of the present invention, during the exercise process, the user may gradually change the connection points on the tensile cord and the vest, handle or harness so as to change the amount and/or direction of resistance felt on the handle or harness (and thus the amount of exercise the user moves the muscles and/or muscles engaged by the handle or harness). Ropes of various lengths and weights can be easily carried in the pockets of the vest during the exercise session so that the ropes are conveniently accessed so that the user can change or add ropes to the vest, handle and/or belt during the exercise session. Thus, the combination of features of the present invention enables progressive strength training exercises to be performed while stationary or in motion (e.g., during walking, jogging or running, or on rails or on a route that moves the user away from the starting point). It is believed that the system is capable of performing a new progressive strength training exercise while exercising, thereby enabling a new exercise combining strength training and heart exercise at all fitness levels of the user.

In alternative aspects of the invention, a weight pocket or insert may be added to the pocket on the front and/or back of the vest. Thus, the handles and straps, weight bags or inserts may alter and/or enhance the user's exercise during use of the vest.

Because the disclosed vests, tensile cords, handles and various poles are lightweight and occupy little space, they are portable and easy to transport in automobiles, on airplanes, etc., and they can be used in any selected location (e.g., other homes or hotel rooms). The disclosed devices and systems can be installed and the disclosed methods of use performed at any location with minimal installation effort. The disclosed devices, systems, and associated methods of use avoid drawbacks associated with other types of exercise devices, including high cost, the need for multiple heavy and cumbersome devices, large space requirements, lack of portability, and lack of utility in performing various exercises with one or a few devices. The disclosed devices, systems, and methods of use are not known in the art and are considered a great leap in the state of the art of training and exercise devices and related systems and methods of use.

While the preferred embodiment of the present invention includes attachment means in the form of snap-lock openable and closable hooks between the components (tensile cord, dorsal loop, handle), it will be appreciated that other attachment means may be utilized. For example, the tensile cord may be tied to or threaded through a vest or hand grip, a velcro or snap-fit connection may be used, and other functionally equivalent mechanisms may be used.
