This disclosure relates in general to exercise devices. More specifically, this disclosure relates to devices and methods that isolate muscle groups during exercise.
For example, in exercises where the user must use forearm strength, tendons, and joints to stabilize and perform the exercise movement, there is much stress on all joints and ligaments. In addition, the stress load on the forearm muscles may be too great to complete a set of the exercise in which the intended muscle group is stressed to satisfaction.
Some related art exercise devices require the user to grip a weight in order to perform an exercise. Other related art exercise devices do not allow the wrist to have free range of motion, and/or require the user to tightly secure a strap to the wrist. Typical wrist straps were designed for only dead lifts or where grip strength hinders workload. Other wrist straps focus on stabilizing the wrist to prevent injury.
Exemplary embodiments of the invention provide devices and methods for isolating muscle groups during exercise. According to an aspect of the invention, a device includes a first strap that has a first loop shape, a second strap that has a second closed loop shape defining a fixed opening, and a third strap that has a third closed loop shape. A first portion of the first strap is affixed to or integral with the second strap, a second portion of the first strap is arranged to be movable within the fixed opening defined by the second closed loop shape, the second portion of the first strap is affixed to or integral with the third strap, and a first adjustable opening within the first loop shape is configured to be adjusted by changing a relative position of the second portion of the first strap and the fixed opening defined by the second closed loop shape.
A size of the first adjustable opening within the first loop shape may be configured to be increased by moving the second portion of the first strap through the fixed opening defined by the second closed loop shape in a first direction, and the size of the first adjustable opening within the first loop shape may be configured to be decreased by moving the second portion of the first strap through the fixed opening defined by the second closed loop shape in a second direction that is different from the first direction. A size of a second adjustable opening within the first loop shape may be configured to be decreased by moving the second portion of the first strap through the fixed opening defined by the second closed loop shape in the first direction, and the size of the second adjustable opening defined by the first loop shape may be configured to be increased by moving the second portion of the first strap through the fixed opening defined by the second closed loop shape in the second direction. The second direction may be opposite to the first direction.
The first strap may include nylon, cotton, polyester, and/or leather. Similarly, the second strap may include nylon, cotton, polyester, and/or leather.
The device may also include a flexible material that covers a section of the second portion of the first strap. The section of the second portion of the first strap may be adjacent to the first adjustable opening. The flexible material may include neoprene. A surface of the flexible material that faces the first adjustable opening may be smooth.
The second portion of the first strap may be integral with the third strap. The third closed loop shape may be configured to receive a connector. The connector may be a hook, a clip, and/or a carabineer.
The third closed loop shape may be formed by attaching the second portion of the first strap to a third portion of the first strap. The second closed loop shape may be secured by a stitching. The second closed loop shape may be secured by a metal snap fastener. The first adjustable opening may be configured to accommodate an appendage of a body when the first adjustable opening is adjusted to a minimum size.
According to another aspect of the invention, a method includes adjusting a first adjustable opening within a first loop shape of a first strap by changing a relative position of the first strap with respect to a fixed opening defined by a second closed loop shape of a second strap. A first portion of the first strap is attached to or integral with the second strap, a second portion of the first strap is arranged to be movable within the fixed opening defined by the second closed loop shape of the second strap, and adjusting the first adjustable opening comprises applying a force to a third closed loop shape that is affixed to or integral with the second portion of the first strap.
Adjusting the first adjustable opening may also include increasing a size of the first adjustable opening within the first loop shape of the first strap by moving the second portion of the first strap through the fixed opening defined by the second closed loop shape in a first direction. Adjusting the first adjustable opening may also include decreasing a size of the first adjustable opening within the first loop shape of the first strap by moving the second portion of the first strap through the fixed opening defined by the second closed loop shape in a second direction. The force may be applied through a connector that is connected to the third closed loop shape of the third strap.

Further, the devices eliminate the reliance on grip strength for performing the exercise.
The first portion 110 of the first strap 105 may be affixed to a second strap 125 that forms a second closed loop shape. The first portion of the first strap 105 may be affixed to the second strap 125 by a fastener, such as stitching and/or glue. The fastener may extend over an entire vertical length of the second strap 125. The second portion 115 of the first strap 105 may extend from the top edge of the first portion 110 of the first strap 105 to a junction with a third strap 145. The third portion 120 of the first strap 105 may extend from the bottom edge of the first portion 110 of the first strap 105 to the junction with the third strap 145.
The second strap 125 may be made of a flexible material, such as nylon, cotton, polyester, and/or leather. The second closed loop shape of the second strap 125 may be secured by a fastener, such as stitching and/or a metal snap. For example, two ends of the second closed loop shape of the second strap 125 may be stitched together or held together by a metal snap with a male component on the first end of the second closed loop shape of the second strap 125 and a female component on the second end of the second closed loop shape of the second strap 125. Alternatively, any other fastener that is capable of fastening the first end of the second closed loop shape of the second strap 125 to the second end of the second closed loop shape of the second strap 125 may be used.
The second closed loop shape of the second strap 125 may define a fixed opening 130. Once the first end of the second closed loop shape of the second strap 125 has been affixed to the second end of the second closed loop shape of the second strap 125, the shape of the fixed opening 130 is constrained by the extent of the second closed loop shape of the second strap 125. Because the second strap 125 may be made of a flexible material, the shape of the fixed opening 130 may be altered somewhat by applying pressure to a portion of the second strap 125, such as by squeezing opposing portions of the second closed loop shape of the second strap 125 together. However, the basic shape and size of the fixed opening 130 may remain the same as determined by the length of the second closed loop shape of the second strap 125.
The second strap 125 may be affixed to the first portion 110 of the first strap 105 such that the second strap 125 is arranged in a plane that is generally perpendicular to a first axis 170, as shown in
The second portion 115 of the first strap 105 and the third portion 120 of the first strap 105 may be affixed to or integrated with the third strap 145, which forms a third closed loop shape. The second portion 115 of the first strap 105 and the third portion 120 of the first strap 105 may be affixed to the third strap 145 by fasteners, such as stitching and/or glue. The fasteners may extend over a portion of the vertical length of the third strap 145. Alternatively, the second portion 115 of the first strap 105 and/or the third portion 120 of the first strap 105 may form the third strap 145, as shown in
The third strap 145 may be made of a flexible material, such as nylon, cotton, polyester, and/or leather. The flexible material may have sufficient strength to withstand a force that is applied while using the exercise device 100 to perform an exercise. The third closed loop shape of the third strap 145 may be secured by a fastener, such as stitching and/or a metal snap. For example, two ends of the third closed loop shape of the third strap 145 may be stitched together or held together by a metal snap with a male component on the first end of the third closed loop shape of the third strap 145 and a female component on the second end of the third closed loop shape of the third strap 145. Alternatively, any other fastener that is capable of fastening the first end of the third closed loop shape of the third strap 145 to the second end of the third closed loop shape of the third strap 145 may be used.
The third closed loop shape may be formed by attaching the second portion 115 of the first strap 105 to the third portion 120 of the first strap 105. For example, the end of the third portion 120 of the first strap 105 may be looped around and affixed to another section of the third portion 120 of the first strap 105 to form an inner portion of the third closed loop shape. Further, the end of the second portion 115 of the first strap 105 may be looped around and affixed to the third portion 120 of the first strap 105 to form an outer portion of the third closed loop shape that is adjacent to the inner portion of the third closed loop shape.
The second portion 115 of the first strap 105 may be threaded through the fixed opening 130 defined by the second closed loop shape of the second strap 125. The second portion 115 of the first strap 105 is not attached to the second strap 125. Instead, the second portion 115 of the first strap 105 is arranged to be movable within the fixed opening 130 defined by the second closed loop shape of the second strap 125.
The first loop shape of the first strap 105 may define a first adjustable opening 135 and a second adjustable opening 140. The size and shape of the first adjustable opening 135 and the second adjustable opening 140 may be adjusted by moving the second portion 115 of the first strap 105 with respect to the fixed opening 130 defined by the second closed loop shape of the second strap 125. Alternatively or in addition, the size and shape of the first adjustable opening 135 and the second adjustable opening 140 may be adjusted by moving the fixed opening 130 defined by the second closed loop shape of the second strap 125 with respect to the second portion 115 of the first strap 105. As the size of the first adjustable opening 135 increases, the size of the second adjustable opening 140 decreases proportionally. Similarly, as the size of the first adjustable opening 135 decreases, the size of the second adjustable opening 140 increases proportionally.
For example, the size of the first adjustable opening 135 may be increased by moving the second portion 115 of the first strap 105 through the fixed opening 130 defined by the second closed loop shape of the second strap 125 in a first direction 180. This causes a corresponding decrease in the size of the second adjustable opening 140.
Similarly, the size of the first adjustable opening 135 may be decreased by moving the second portion 115 of the first strap 105 through the fixed opening 130 defined by the second closed loop shape of the second strap 125 in a second direction 185 that is different from the first direction 180. This causes a corresponding increase in the size of the second adjustable opening 140. The second direction 185 may be opposite to the first direction 180. A force may be applied in the second direction 185 via the third closed loop shape of the third strap 145. For example, the force may adjust the size of the first adjustable opening 135 such that the portion of the first strap 105 defining the first adjustable opening 135 fits securely around an appendage of a user that has been inserted through the first adjustable opening 135.
The first adjustable opening 135 may be configured to accommodate an appendage of a user when the first adjustable opening 135 is adjusted to a minimum size. For example, the first adjustable opening 135 may be configured to accommodate a wrist, ankle, foot, or neck of the user. The length of the first strap 105 and/or the location of the first portion 110 of the first strap 105 where the second strap 125 is affixed may define a range of minimum sizes of the first adjustable opening 135. Because the first strap 105 can be made longer or shorter, and the location where the second strap 125 may be affixed to the first strap 105 can be varied, appendages having different sizes can be accommodated.
The first portion 210 of the first strap 205 may be affixed to a second strap 225 that forms a second closed loop shape. The first portion of the first strap 205 may be affixed to the second strap 225 by a fastener, such as stitching and/or glue. The fastener may extend over an entire vertical length of the second strap 225. The second portion 215 of the first strap 105 may extend from the top edge of the first portion 210 of the first strap 205 to a junction with a third strap 245. The third portion 220 of the first strap 205 may extend from the bottom edge of the first portion 210 of the first strap 205 to the junction with the third strap 245.
The second strap 225 may be made of a flexible material, such as nylon, cotton, polyester, and/or leather. The second closed loop shape of the second strap 225 may be secured by a fastener, such as stitching and/or a metal snap. For example, two ends of the second closed loop shape of the second strap 225 may be stitched together or held together by a metal snap with a male component on the first end of the second closed loop shape of the second strap 225 and a female component on the second end of the second closed loop shape of the second strap 225. Alternatively, any other fastener that is capable of fastening the first end of the second closed loop shape of the second strap 225 to the second end of the second closed loop shape of the second strap 225 may be used.
The second closed loop shape of the second strap 225 may define a fixed opening 230. Once the first end of the second closed loop shape of the second strap 225 has been affixed to the second end of the second closed loop shape of the second strap 225, the shape of the fixed opening 230 is constrained by the extent of the second closed loop shape of the second strap 225. Because the second strap 225 may be made of a flexible material, the shape of the fixed opening 230 may be altered somewhat by applying pressure to a portion of the second strap 225, such as by squeezing opposing portions of the second closed loop shape of the second strap 225 together.

The second portion 215 of the first strap 205 and the third portion 220 of the first strap 205 may be affixed to or integrated with the third strap 245, which forms a third closed loop shape. The second portion 215 of the first strap 205 and the third portion 220 of the first strap 205 may be affixed to the third strap 245 by fasteners, such as stitching and/or glue. The fasteners may extend over a portion of the vertical length of the third strap 245. Alternatively, the second portion 215 of the first strap 205 and/or the third portion 220 of the first strap 205 may form the third strap 245, as shown in
The third strap 245 may be made of a flexible material, such as nylon, cotton, polyester, and/or leather. The flexible material may have sufficient strength to withstand a force that is applied while using the exercise device 200 to perform an exercise. The third closed loop shape of the third strap 245 may be secured by a fastener, such as stitching and/or a metal snap. For example, two ends of the third closed loop shape of the third strap 245 may be stitched together or held together by a metal snap with a male component on the first end of the third closed loop shape of the third strap 245 and a female component on the second end of the third closed loop shape of the third strap 245. Alternatively, any other fastener that is capable of fastening the first end of the third closed loop shape of the third strap 245 to the second end of the third closed loop shape of the third strap 245 may be used.
The third closed loop shape may be formed by attaching the second portion 215 of the first strap 205 to the third portion 220 of the first strap 205. For example, the end of the third portion 220 of the third strap 205 may be looped around and affixed to another section of the third portion 220 of the first strap 205 to form an inner portion of the third closed loop shape. Further, the end of the second portion 215 of the first strap 205 may be looped around and affixed to the third portion 220 of the first strap 205 to form an outer portion of the third closed loop shape that is adjacent to the inner portion of the third closed loop shape.
The second portion 215 of the first strap 205 may be threaded through the fixed opening 230 defined by the second closed loop shape of the second strap 225. The second portion 215 of the first strap 205 is not attached to the second strap 225. Instead, the second portion 215 of the first strap 205 is arranged to be movable within the fixed opening 230 defined by the second closed loop shape of the second strap 225.
The first loop shape of the first strap 205 may define a first adjustable opening 235 and a second adjustable opening 240. The size and shape of the first adjustable opening 235 and the second adjustable opening 240 may be adjusted by moving the second portion 215 of the first strap 205 with respect to the fixed opening 230 defined by the second closed loop shape of the second strap 225. Alternatively or in addition, the size and shape of the first adjustable opening 235 and the second adjustable opening 240 may be adjusted by moving the fixed opening 230 defined by the second closed loop shape of the second strap 225 with respect to the second portion 215 of the first strap 205. As the size of the first adjustable opening 235 increases, the size of the second adjustable opening 240 decreases proportionally. Similarly, as the size of the first adjustable opening 235 decreases, the size of the second adjustable opening 240 increases proportionally.
For example, the size of the first adjustable opening 235 may be increased by moving the second portion 215 of the first strap 205 through the fixed opening 230 defined by the second closed loop shape of the second strap 225 in a first direction 280. This causes a corresponding decrease in the size of the second adjustable opening 240.
Similarly, the size of the first adjustable opening 235 may be decreased by moving the second portion 215 of the first strap 205 through the fixed opening 230 defined by the second closed loop shape of the second strap 225 in a second direction 285 that is different from the first direction 280. This causes a corresponding increase in the size of the second adjustable opening 240. The second direction 285 may be opposite to the first direction 280. A force may be applied in the second direction 285 via the third closed loop shape of the third strap 245. For example, the force may adjust the size of the first adjustable opening 235 such that the portion of the first strap 205 defining the first adjustable opening 235 fits securely around an appendage of a user that has been inserted through the first adjustable opening 235. The force may be applied via the connector 250 that is connected to the third strap 245.
The first adjustable opening 235 may be configured to accommodate an appendage of a user when the first adjustable opening 235 is adjusted to a minimum size. For example, the first adjustable opening 235 may be configured to accommodate a wrist, ankle, foot, or neck of the user. The length of the first strap 205 and/or the location of the first portion 210 of the first strap 205 where the second strap 225 is affixed may define a range of minimum sizes of the first adjustable opening 235. Because the first strap 205 can be made longer or shorter, and the location where the second strap 225 may be affixed to the first strap 205 can be varied, appendages having different sizes can be accommodated.

However, the basic shape and size of the fixed opening 530 may remain the same as determined by the length of the second closed loop shape of the second strap 525.
The second strap 525 may be affixed to the first portion 510 of the first strap 505 such that the second strap 525 is arranged in a plane that is generally perpendicular to a first axis 570, as shown in
The second portion 515 of the first strap 505 may be affixed to or integrated with the third strap 545, which forms a third closed loop shape. The second portion 515 of the first strap 505 may be affixed to the third strap 545 by fasteners, such as stitching and/or glue. The fasteners may extend over a portion of the vertical length of the third strap 545. Alternatively, the second portion 515 of the first strap 505 may form the third strap 545, as shown in
The third strap 545 may be made of a flexible material, such as nylon, cotton, polyester, and/or leather. The flexible material may have sufficient strength to withstand a force that is applied while using the exercise device 500 to perform an exercise. The third closed loop shape of the third strap 545 may be secured by a fastener, such as stitching and/or a metal snap. For example, two ends of the third closed loop shape of the third strap 545 may be stitched together or held together by a metal snap with a male component on the first end of the third closed loop shape of the third strap 545 and a female component on the second end of the third closed loop shape of the third strap 545. Alternatively, any other fastener that is capable of fastening the first end of the third closed loop shape of the third strap 545 to the second end of the third closed loop shape of the third strap 545 may be used.
The third closed loop shape may be formed by looping the end of the second portion 515 of the first strap 505 and affixing the end of the second portion 515 of the first strap 505 to another section of the second portion 515 of the first strap 505. Further, the end of the second portion 515 of the first strap 505 may be affixed to the other section of the second portion 515 of the first strap 505 by a fastener, such as stitching and/or glue.
The second portion 515 of the first strap 505 may be threaded through the fixed opening 530 defined by the second closed loop shape of the second strap 525. The second portion 515 of the first strap 505 is not attached to the second strap 525. Instead, the second portion 515 of the first strap 505 is arranged to be movable within the fixed opening 530 defined by the second closed loop shape of the second strap 525.
The first loop shape of the first strap 505 may define a first adjustable opening 535. The size and shape of the first adjustable opening 535 may be adjusted by moving the second portion 515 of the first strap 505 with respect to the fixed opening 530 defined by the second closed loop shape of the second strap 525. Alternatively or in addition, the size and shape of the first adjustable opening 535 may be adjusted by moving the fixed opening 530 defined by the second closed loop shape of the second strap 525 with respect to the second portion 515 of the first strap 505.
For example, the size of the first adjustable opening 535 may be increased by moving the second portion 515 of the first strap 505 through the fixed opening 530 defined by the second closed loop shape of the second strap 525 in a first direction 580. Similarly, the size of the first adjustable opening 535 may be decreased by moving the second portion 515 of the first strap 505 through the fixed opening 530 defined by the second closed loop shape of the second strap 525 in a second direction 585 that is different from the first direction 580. The second direction 585 may be the opposite direction of the first direction 580. A force may be applied in the second direction 585 via the third closed loop shape of the third strap 545. For example, the force may adjust the size of the first adjustable opening 535 such that the portion of the first strap 505 defining the first adjustable opening 535 fits securely around an appendage of a user that has been inserted through the first adjustable opening 535.
The first adjustable opening 535 may be configured to accommodate an appendage of a user when the first adjustable opening 535 is adjusted to a minimum size. For example, the first adjustable opening 535 may be configured to accommodate a wrist, ankle, foot, or neck of the user. The length of the first strap 505 and/or the location of the first portion 510 of the first strap 505 where the second strap 525 is affixed may define a range of minimum sizes of the first adjustable opening 535. Because the first strap 505 can be made longer or shorter, and the location where the second strap 525 may be affixed to the first strap 505 can be varied, appendages having different sizes can be accommodated.
As shown in
The flexible material 560 may be affixed to the second portion 515 of the first strap 505 by a fastener, such as stitching and/or glue. The flexible material 560 may be affixed to the second portion 515 of the first strap 505 at a single location adjacent to the first portion 510 of the first strap 505. Alternatively or in addition, the flexible material 560 may be affixed to the second portion 515 of the first strap 505 at multiple locations.
