In order to describe the manner in which the above and other features of the present disclosure are achieved, a more specific description will be made with reference to the specific embodiments illustrated in the accompanying drawings. For better understanding, the same elements are represented by the same element symbols in the various drawings. While some of the drawings may be schematic or exaggerated conceptual representations, at least some of the drawings may be drawn to scale. It will be appreciated that the accompanying drawings depict some exemplary embodiments, which will be described and explained with additional specificity and detail through use of the drawings, wherein: Figure 1 illustrates a rowing machine in accordance with at least one embodiment of the present disclosure. Representation; Figure 2 is a representation of a top view of a rowing machine according to at least one embodiment of the present disclosure; Figure 3-1 is a representation of a handle in a connected position according to at least one embodiment of the present disclosure; Figure 3-2 is a representation of the grip of Figure 3-1 in a separated position; Figure 4 is a representation of another grip in a separated position according to at least one embodiment of the present disclosure; Figures 5-1 to 5-4 is an illustration of a pedal in accordance with at least one embodiment of the present disclosure; and FIG. 6 is an illustration of a method for securing a user's feet to a rowing machine in accordance with at least one embodiment of the present disclosure.

The present disclosure generally relates to devices, systems, and methods for rowing machines that may be used in rowing, kayaking, canoeing, and other configurations. Rowing machines have a flywheel and two cables, each of which can independently apply torque to the flywheel. Cables can be attached to the grip. The grip can consist of two parts. The two parts are connected to the two grips. The two parts can be connected to each other via removable connections. When these two parts are connected, the rowing machine can be used in a rowing configuration. When the two halves are disconnected, each can pull the flywheel independently. A spreader can be connected between these two parts to extend the length of the grip. In some embodiments, with the pole in place, the user can simulate canoe movement through the grip. In this manner, the rowing machine can be a convertible rowing machine that can be used in a variety of configurations. This increases the versatility of the rowing machine, thereby improving the user experience.

In some embodiments, a rowing machine may include pedals upon which a user may rest his or her feet for support during the rowing motion. pedal Can include platforms. The toe strap can be located at the front end of the platform, and the plurality of heel buckles can be located at the rear end of the platform. During use, the user can insert his or her toes into the toe strap. The user's heel can depress one or more heel buckles. As the user inserts his toes further into the toe strap, one or more of the depressed heel buckles may move rearwardly away from the platform. This may move the heel buckle above the user's heel. Contact between the user's heel and the heel buckle can help secure the user's foot to the pedal. This provides the user with a safer foot placement on the platform, preventing the foot from moving during the rowing motion.

Figure 1 is a representation of a perspective view of a rowing machine 100 in accordance with at least one embodiment of the present disclosure. The rowing machine 100 shown includes a sliding base 102 . During use, the user may sit on the sliding base 102 and place his or her feet on the pedals 104 . The user can grasp the handle 106 connected to the cable 108. The user can pull the handle 106. This pulls cable 108 which in turn turns flywheel 110 . Flywheel 110 can provide rotational resistance. When the user pulls on the handle 106, the user can push on the pedal 104 with his or her feet. As the cable 108 extends, and as the user pushes the pedal 104 with his or her feet, the sliding base 102 can slide rearwardly on the frame 112 . The rotational resistance of flywheel 110 may be transferred to cable 108 such that the force that would be applied to the cable rotates flywheel 110 .

Cable 108 can be biased to a retracted position where cable 108 is pulled within rowing machine 100 . When the user has completed pulling on the handle 106 (e.g., when the user's legs are extended), the sliding base 102 slides back on the frame 112, and/or the user has moved his or her arms toward Pulling on his or her chest), the user can move closer to flywheel 110 and cable 108 can be retracted. This action can be repeated multiple times with rowing exercises.

Figure 2 is a schematic representation of a top view of a rowing machine 200 in accordance with at least one embodiment of the present disclosure. The rowing machine 200 shown includes a flywheel 210 that is pulled by two cables (collectively 208). Each cable 208 can turn flywheel 210 independently. In other words, the user can rotate the flywheel 210 by pulling the first cable 208-1 or the second cable 208-2. The cables 208 can be independent, meaning that the user can pull only the first cable 208-1 and not the second cable 208-2 during athletic activities, or vice versa.

The first cable 208-1 and the second cable 208-2 may be connected to the grip 206. In certain embodiments, a first cable 208-1 can be connected to the first end 214-1 of the grip 206, and a second cable 208-2 can be connected to the second end 214-2 of the grip 206. During athletic activity, the user can pull on the handle 206 to perform the athletic activity. For example, the user can perform a rowing motion by pulling on the handle 206 to evenly extend the cable 208 (eg, extending the first cable 208-1 and the second cable 208-2 at the same rate simultaneously). As described herein, during rowing activities, a user may sit on the sliding base 102 and place his or her feet on the pedals. The user can pull the handle 206 by hand to extend the cable 208, thereby turning the flywheel 210. In some embodiments, the sliding base 102 can be connected to the frame 212 by a sliding connection, and the user can push his or her legs against the pedal 204 to help pull the handle 206 .

In the embodiment shown, grip 206 is a wide grip. For example, the grip 206 may have a width wider than the user's shoulder blades. This may allow the user to exercise different muscles during rowing activity. For example, the user can place his or her hands on the grip 206 at different widths apart to exercise different muscles.

In some embodiments, the grip 206 may be a modular grip or an adjustable grip. The grip 206 may include a first portion 216-1 and a second portion 216-2. The first cable 208-1 can be connected to the first portion 216-1 and the second cable 208-2 can be connected to the second portion 216-2. The first portion 216-1 and the second portion 216-2 may be selectively coupled or connected to each other. As shown in Figure 3-1, first portion 216-1 may be directly coupled or connected to second portion 216-2. In certain embodiments, the grip accessory 218 may be connected to one or both of the first portion 216-1 or the second portion 216-2. In the embodiment shown in Figure 2, the grip accessory 218 may be a spreader. A strut may be placed between the first portion 216-1 and the second portion 216-2 to extend the width of the grip 206. This may allow the user to exercise different muscles by placing his or her hands in different positions on the grip 206.

In some embodiments, the pole grip accessory 218 may be used to extend the grip 206 to simulate kayak paddling. The dinghy paddle can be wider than the rowing machine's grip 206 to simulate the action of a sliding dinghy. Dinghy paddles used on the water include a shaft that supports the paddle at either end. To propel the boat forward, the user lowers one end of the shaft and raises the other end of the shaft to position the paddle in the water in front of the user. The user can pull the paddle towards him or herself and pull the paddle out of the water. The user can then lower the second blade while raising the first blade to bring the second blade into contact with the water and pull the second blade back. Then, repeat this action indefinitely.

The grip 206 shown in Figure 2 can be used to simulate the motion of a canoe paddle. For example, the user may hold the grip 206 and raise the second portion 216-2 while lowering the first portion 216-1. The user may then pull back on first portion 216-1 (eg, away from flywheel 210, toward sliding base 102). This action may extend the first cable 208-1 without extending the second cable 208-2 or while retracting the second cable 208-2. The user can then lower the second portion 216-2 while raising the first portion 216-1. The user can then pull back on the second portion 216-2 (eg, away from the flywheel 210, toward the sliding base 102). This action may extend the second cable 208-2 without extending the first cable 208-1 or while retracting the first cable 208-1. In this manner, the user can simulate the movements and/or forces experienced when paddling on a dinghy using a dinghy oar.

While paddling, the user on the dinghy can remain in the same position relative to the body of the dinghy. In other words, the seats in a dinghy can be stationary or stationary. In certain embodiments, in a craft configuration as discussed herein, the sliding seat 102 may include a locking mechanism or seat catch. The base buckle can lock the sliding base 102 in place so that the base does not slide along the frame 212 . Using the base buckle can help the user maintain stability and further simulate the paddling motion of a light boat, thus improving the user experience.

In some embodiments, the grip accessory 218 may be a paddle shaft and grip, such as a canoe or dragon boat paddle shaft and grip, or other similar paddle shafts and grips. A canoe paddle has a single blade that extends into the water and has a cross-bar on top for the user to grab onto. Only one oar extends into the water. To simulate the paddling motion of a canoe, the grip fitting 218 may be attached to the first portion 216-1 only. The user may hold the grip assembly 218 vertically or approximately vertically and perform canoe paddling motions through the grip by pushing the first portion 216-1 downward and pulling the first portion 216-1 rearwardly. Because the grip 206 may only be connected to the first cable 208-1, this action may extend only the first cable. As can be appreciated, the accessory may similarly be connected to the second cable 208-2 and simulate canoe paddling motion by extending the second cable 208-2. A modular or configurable grip 206 that can be converted between a rowing configuration, a dinghy configuration, and a canoe configuration can increase the number of exercises that can be performed on the rowing machine 200, thereby increasing its versatility. More available sports can improve the user experience by reducing the number of sports equipment that users can use to perform these sports.

Figure 3-1 is a representation of the handle 306 in a connected position in accordance with at least one embodiment of the present disclosure. Grip 306 includes a first portion 316-1 connected to a second portion 316-2 at grip connection 320. As described herein, the first portion 316-1 and the second portion 316-2 may be selectively connected at the grip connection 320. Therefore, the first part 316-1 can be detached from the second part 316-2 and reconnected, depending on the movement performed, the Grip accessories to be integrated with the grip 306 (eg, grip accessory 218 of Figure 2), any other reasons for attachment, and combinations thereof.

The first part 316-1 includes the first grip 322-1. The first connecting arm 324-1 may be connected to the first grip 322-1. A cable (eg, first cable 208-1 of Figure 2) may be connected to first portion 316-1 at first connecting arm 324-1. The second portion 316-2 includes a second grip 322-2. The second connecting arm 324-2 may be connected to the second grip 322-2. A cable (eg, second cable 208-2 of Figure 2) may be connected to second portion 316-2 at second connecting arm 324-2. Although the connecting arms (collectively 324 ) are shown connected to the handle (collectively 322 ) and extending beyond the handle 322 , it should be understood that the cable may be connected directly to the handle 322 .

The first portion 316-1 can be separated from the second portion 316-2 at the grip connection 320, as shown in Figure 3-2. In Figure 3-2, the first portion 316-1 has been separated from the second portion 316-2 at the grip connection 320. In the embodiment shown, the grip connection 320 is an interlocking connection, such as a dovetail connection. The first portion 316-1 includes a protrusion 326 having at least one overhanging portion. The second portion 316-2 includes a recess 328 that includes at least one complementary overhanging portion. When the protrusion 326 is inserted into the recess 328, the protrusion 326 and the recess 328 may interlock. The interlocking of protrusions 326 and recesses 328 may prevent separation of first portion 316-1 from second portion 316-2. In certain embodiments, the interlocking connection between protrusion 326 and recess 328 may help prevent longitudinal removal, or removal parallel to the longitudinal axis of the grip (collectively 322 ).

In the embodiment shown, the grip connection 320 includes a latch and detent to prevent movement of the first portion 316 - 1 relative to the second portion 316 - 2 along the insertion axis of the projection 326 into the recess 328 . For example, protrusions 326 may include detents 330 or recesses. Recess 328 may include a latch 332 . The latch 332 may be configured to be inserted into the detent 330 . In some embodiments, the latch 332 may be biased outwardly by a spring or other resilient element. The tab 326 may engage the latch 332 when the tab 326 is inserted into the recess 328 . When the first portion 316-1 is fully connected to the second portion 316-2, the latch 332 can be inserted into the detent 330. The latch 332 is resistant to removal from the detent 330 . This may help strengthen the grip connection 320, thereby preventing the first portion 316-1 from separating relative to the second portion 316-2.

Figure 4 is a representation of a grip 406 with a magnetic grip connection 420 in accordance with at least one embodiment of the present disclosure. Magnetic grip connection 420 may include protruding magnets 434 on first portion 416-1 of grip 406, and recessed magnets 436 on second portion 416-2 of grip 406. The protruding magnet 434 and the recessed magnet 436 may have complementary shapes. When connecting first portion 416-1 to second portion 416-2, protruding magnet 434 may be magnetically connected to female magnet 436. The magnetic connection can draw the first part 416-1 to the second part 416-2 and hold the two parts together.

In certain embodiments, magnetic grip connection 420 may include one or more alignment features. Alignment features may help align first portion 416-1 relative to second portion 416-2. In certain embodiments, the complementary shapes of the protruding magnets 434 and the recessed magnets 436 may be complementary. For example, protruding magnets 434 are shown having an arcuate shape, while recessed magnets 436 have dimensions Complementary arcuate shapes similar in shape. When protruding magnet 434 is inserted into female magnet 436, the complementary shapes may orient and align first portion 416-1 relative to second portion 416-2. This may help maintain alignment of first link arm 424-1 relative to second link arm 424-2. Alignment between first connecting arm 424-1 and second connecting arm 424-2 can help maintain first portion 416-1 and second portion while pulling on a rowing machine cable (eg, cable 208 of Figure 2) 416-2 constant pressure.

Figure 5-1 is a representation of a pedal 504 for a rowing machine in accordance with at least one embodiment of the present disclosure. Pedal 504 includes platform 538 . Toe strap 540 is connected to platform 538 at its front end 541 . The pedal 504 also includes a plurality of heel buckles 542 . In some embodiments, the plurality of heel buckles 542 may be arranged longitudinally along the length of the platform 538 . For example, heel buckle 542 is shown disposed in a line between rear end 543 of platform 538 and toe strap 540 . While using pedal 504, the user may slide his or her foot, and more specifically, his or her toes into toe strap 540. To insert his or her toes into toe strap 540, the user can slide his or her toes between platform 538 and toe strap 540. Toe strap 540 may help the user's foot, particularly the user's toes, remain connected to platform 538 .

In some embodiments, toe strap 540 may be a one size fits all toe strap. In certain embodiments, toe strap 540 may be adjustable. For example, toe strap 540 may include a tightening mechanism such as a latch, hook and eye straps, buttons, cables, knobs, any other tightening mechanism, and combinations thereof. In certain embodiments, toe strap 540 may be formed from a resilient material and may be oriented toward use The person's feet push against each other. In some embodiments, toe strap 540 can be connected to a motor, and the motor can tighten toe strap 540 .

Heel buckle 542 may be secured to platform 538 and biased above platform 538 . Heel buckle 542 may be connected to platform 538 at buckle connectors (collectively 544). The heel buckle 542 can extend toward the rear end 543 of the platform 538 through the extension portion 546 . The heel buckle 542 may extend from the first buckle connector 544-1 to the rearward end 543, loop through the extension portion 546, and extend rearwardly toward the second buckle connector 544-2.

In some embodiments, extension 546 may be biased upward and away from platform 538 . In some embodiments, extension 546 may be biased away from platform 538 such that there is space between extension 546 and platform 538 . For example, extension 546 may be biased above platform 538 such that there is a gap below extension 546 and platform 538 .

When a user inserts his or her foot into toe strap 540, the user may insert his or her foot in a forward direction (eg, from rear end 543 toward front end 541). When inserting the foot, the user can push down on one or more heel buckles 542 with his or her heel. For example, the user's heel may press down on the extension 546 of the one or more heel buckles 542, thereby depressing the one or more heel buckles. This may move the extension 546 of one or more heel buckles 542 toward the platform 538 .

The plurality of heel buckle portions 542 can be independently actuated. For example, each of the plurality of heel buckles 542 may be connected to the platform 538 via a separate buckle connector 544 . Therefore, each heel buckle The portion 542 can be depressed and/or released independently of the remaining heel buckle portion 542 . In some embodiments, at least one rear heel buckle 542 may be maintained in an undepressed state (eg, at least one heel buckle 542 may be maintained in a neutral position). The at least one rear heel buckle 542 may be the first undepressed heel buckle 542 between the user's heel and the rear end 543 .

As the user pushes his or her foot toward the front end 541 and further into the toe strap 540, the user's heel may expose (eg, release) one or more extensions 546 of the heel buckle 542. Because the extension 546 is biased away from the platform 538 , the extension 546 may move away from the platform 538 when the extension 546 is exposed. The newly exposed heel buckle 542 may become the rear heel buckle 542 . The user's heel may then be positioned between the toe strap 540 and the rearward extension 546 of the heel buckle 542 .

When the user has fully inserted his or her foot into toe strap 540 , the user's heel may be positioned between at least one extension 546 of heel buckle 542 and toe strap 540 . Because the extension portion 546 extends above the platform 538, a portion of the extension portion 546 may be located further above the user's heel. The extension 546 may contact the user's heel and prevent rearward movement of the foot (eg, toward rear end 543). In this manner, heel buckle 542 may assist the user in retaining the foot within pedal 504 . By preventing the user's feet from slipping during athletic activities, the user's stability during athletic activities can be increased.

As can be seen, extension 546 has a curved profile or shape. The curved profile or shape of extension 546 may help secure the user's foot against backward movement of the foot (eg, toward rear end 543). In certain embodiments, the curved profile or shape of extension 546 may help secure the user's foot against lateral movement of the foot (eg, lateral movement relative to front end 541 and rear end 543). Combined with the user's toes being strapped in the toe strap 540, the user's feet can be securely connected or secured to the pedals 504 during athletic activities. This may improve the user's stability during athletic activities, thereby reducing the chance of injury due to the user's feet slipping off the platform 538.

In some embodiments, the user can pull the extension portion 546 of the heel buckle 542 upward to engage the user's heel. This may allow the user to place the extension 546 in a comfortable position on his or her heel. For example, the user may place extension 546 on his or her Achilles tendon, on top of the heel bone, in the center of the heel bone, at the bottom of the heel bone, or at any other location on the user's heel. superior. In this manner, the user can customize the comfort of the connection between the heel buckle 542 and the user's foot.

As shown in FIG. 5-1 , the pedal 504 includes a plurality of heel buckle portions 542 . For example, in the embodiment shown, there are seven heel buckles 542 . Including multiple heel buckles 542 may allow multiple users with different foot sizes to use the pedal 504 . For example, a user with smaller feet may engage the heel buckle 542 with his or her heel closer to the front end 541 of the platform 538 . Users with larger foot sizes can use his or her feet Heel, engages the heel buckle 542 closer to the rear end 543 of the platform 538 . Therefore, by including multiple heel buckles 542, multiple users with different sized feet can use the same pedal 504. This increases the versatility of the exercise device.

In some embodiments, heel buckle 542 may not have any adjustment mechanism. The length of the heel buckle 542 may be fixed, and there may not be any straps, buckles, buttons, or other adjustment mechanisms to change the length of the heel buckle 542 . The adjustability of the pedal 504 to available foot sizes may be based, at least in part, on the number of heel buckles 542 disposed between the front end 541 and the rear end 543 of the platform 538 .

In some embodiments, heel buckle 542 may be formed from a resilient material. For example, the heel buckle 542 may be formed of elastically deformable plastic, rubber, or other synthetic materials. When the heel buckle 542 is secured to the user's foot, the heel buckle 542 may deform to at least partially match the shape of the user's foot. Elastically deformable materials are generally softer and increase user comfort. In some embodiments, the elastically deformable material of heel buckle 542 may apply a retaining force to the user's foot. For example, the user's foot may be prevented from moving in a forward direction (eg, toward the front end 541 ) by the toe strap 540 . The elastically deformable heel buckle 542 can push the user's foot upward against the toe strap 540 to secure the foot snugly within the pedal 504 .

In some embodiments, the elastically deformable material of heel buckle 542 may bias extension 546 above platform 538 . Heel buckle 542 may have a neutral shape with extension 546 located above platform 538 . When the user's heel is pushed down against the extension 546 , the heel buckle 542 can elastically deform and be pushed against the platform 538 . When the user's heel is removed from the extension 546 , the elastically deformable material allows the heel buckle 542 to return to a neutral position with the extension 546 above the platform 538 .

Buckle connector 544 may form a hinge between platform 538 and extension 546 . When the user presses the extension 546 toward the platform 538, the heel buckle 542 can rotate at the buckle connector 544. In some embodiments, buckle connector 544 may be elastically deformable. When the user presses the extension 546 toward the platform 538, the buckle connector 544 can elastically deform to allow the extension 546 to move. When the user's foot is removed from extension 546, buckle connector 544 returns to its neutral shape, which moves extension 546 back to the neutral position.

In some embodiments, buckle connector 544 may be formed from a mechanical hinge. For example, buckle connector 544 may include a spring hinge. For example, the buckle connector may include a coil spring, a leaf spring, a torsion spring, a clock spring, any other type of spring, and combinations thereof. The spring hinge may have a longer service life, thereby reducing the chance of the heel buckle 542 breaking at one or both buckle connectors 544.

In some embodiments, platform 538 may include one or more depressions 548 . Recess 548 may be positioned beneath heel buckle 542 . The shape of the recess 548 may be complementary to the heel buckle 542 (eg, have the same shape and size). When the user pushes the heel buckle 542 downward, the heel buckle 542 can extend into the recess 548 . When the heel buckle 542 is When pushed onto platform 538, heel buckle 542 may be flush with the surface of the platform. Since the user may depress at least one heel buckle 542 during the user's activities, pushing the heel buckle 542 into the recess 548 may provide the user with a flat or nearly flat surface to use when performing athletic activities. The user pushes to help improve the user's comfort. This improves the sports experience.

Figure 5-2 is a representation of a side view of pedal 504 of Figure 5-1. As can be seen in the side view, toe strap 540 may extend above platform 538 at toe strap height 550. In certain embodiments, toe strap height 550 may be configured to allow the user's toes to be secured to platform 538 . In certain embodiments, toe strap height 550 may be configured to secure the user's foot to platform 538 at the user's toes.

In certain embodiments, toe strap height 550 may be 2 cm, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm, or any value therebetween. As described herein, toe strap 540 may be adjustable such that toe strap height 550 is adjustable.

Heel buckle 542 has a gap between platform 538 and heel buckle 542 . This gap may extend the buckle height 552. In some embodiments, button height 552 may be 0.5 cm, 1 cm, 1.5 cm, 2 cm, 2.5 cm, 3 cm, 3.5 cm, 4 cm, 4.5 cm, 5 cm, or any value therebetween. Buckle height 552 may be sized to allow heel buckle 542 to engage the user's foot at the heel of his or her foot.

As can be seen in the top view of FIG. 5-3 , the heel buckle 542 has a buckle length 554 , which may be the length of the heel buckle 542 between the buckle connector 544 and the extension 546 . In certain embodiments, button length 554 may be 2 cm, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm, 12 cm, 14 cm, 16 cm, 18 cm, 20 cm, or any value therebetween. The size of the buckle length 554 can fit the average user's feet. In some embodiments, each heel buckle 542 may have the same buckle length 554. In some embodiments, different heel buckles 542 may have different buckle lengths 554 . For example, a heel buckle 542 located closer to the toe strap 540 may have a shorter buckle length 554 than a heel buckle 542 located further from the toe strap 540 . This can help expand the range of user foot sizes that can comfortably use pedal 504.

Figure 5-4 is a front view of the pedal 504 of Figure 5-1. As can be seen, toe strap 540 extends further above platform 538 than heel buckle 542 . When the user places his or her foot in the pedal 504, the user can pull the heel buckle 542 upward to rest comfortably on his or her foot.

Figure 6 is a flowchart of a method 660 for securing a user's feet to a rowing machine in accordance with at least one embodiment of the present disclosure. Method 660 includes, at 662, inserting the toes of the user's foot under a toe strap connected to a platform of a pedal that is connected to the rowing machine. Method 660 may include, at 664, depressing one or more heel buckles of a plurality of heel buckles connected to the platform. As described herein, depression of one or more heel buckles allows a user to position his or her foot based on the size of the user's foot. The result of the insertion of the toe into the toe strap, or at least in part the result of the action described above. In some embodiments, when the user slides his or her foot into position, one or more heel buckles are released (eg, moved to a neutral position). Method 660 may also include, at 666, securing the user's foot to the platform via the rear heel buckle. The rear heel buckle may be oriented behind the at least one depressed heel buckle. The rear heel buckle may be undepressed (eg, the heel buckle may be in a neutral position). During athletic activities, the rear heel buckle can contact the user's heel to secure the user's foot to the pedal.

Industrial applicability

The present disclosure generally relates to devices, systems, and methods that may be used with rowing machines in rowing boats, boats, canoes, and other configurations. Rowing machines have a flywheel and two cables, each of which can independently apply torque to the flywheel. Cables can be attached to the grip. The grip can consist of two parts. The two parts are connected to the two grips. The two parts can be connected to each other via removable connections. When these two parts are connected, the rowing machine can be used in a rowing configuration. When the two halves are disconnected, each can pull the flywheel independently. A strut can be connected between these two parts to extend the length of the grip. In some embodiments, with the pole in place, the user may be able to simulate boat movement with the grip. In this manner, the rowing machine can be a convertible rowing machine that can be used in a variety of configurations. This increases the versatility of the rowing machine, thereby improving the user experience.

In some embodiments, a rowing machine may include pedals upon which a user may rest his or her feet during rowing motions. Pedal can to include the platform. The toe strap can be located at the front end of the platform, and the plurality of heel buckles can be located at the rear end of the platform. During use, the user can insert his or her toes into the toe strap. The user's heel can depress one or more heel buckles. As the user inserts his toes further into the toe strap, one or more of the depressed heel buckles may move rearward away from the platform. This may move the heel buckle above the user's heel. Contact between the user's heel and the heel buckle can help secure the user's foot to the pedal. This provides the user with a safer foot placement on the platform, preventing the foot from moving during the rowing motion.

In some embodiments, the rowing machine includes a sliding base. During use, the user can sit on the sliding base and place his or her feet on the pedals. The user can grasp the grip attached to the cable. The user can pull the handle. This may pull on the cable, causing the flywheel to spin. The flywheel provides rotational resistance. When the user pulls on the handle, the user can push the pedal with his or her feet. As the cable extends, and as the user pushes the pedal with his or her foot, the sliding base can slide back on the frame. The rotational resistance of the flywheel can be transferred to the cable, causing the force that would be applied to the cable to rotate the flywheel.

The cable can be biased to a retracted position where it is pulled within the rowing machine. The sliding base slides back on the frame when the user has finished pulling on the handle (e.g. when the user's legs are extended), and/or the user has pulled his or her arms towards his or her chest ), the user can move closer to the flywheel and the cable can be retracted. This action can be repeated multiple times with rowing exercises.

In some embodiments, the rowing machine includes a flywheel pulled by two cables. Each cable can turn the flywheel independently. In other words, the user can rotate the flywheel by pulling the first cable or the second cable. The cables can be independent, meaning that the user can pull only the first cable and not the second cable during athletic activities, or vice versa.

The first cable and the second cable can be connected to the grip. In some embodiments, a first cable can be connected to the first end of the grip and a second cable can be connected to the second end of the grip. During athletic activity, the user can pull on the handle to perform the athletic activity. For example, the user can perform a rowing motion by pulling on the handle to extend the cables evenly (eg, extending the first cable and the second cable at the same rate simultaneously). As described in the description herein, during rowing activities, the user can sit on the sliding base and place his feet on the pedals. The user can turn the flywheel by pulling on the handle with their hand to extend the cable. In some embodiments, the sliding base can be connected to the frame by a sliding connection, and the user can push his or her legs against the pedal to help pull the handle.

In the embodiment shown, the grip is a wide grip. For example, the grip may have a width wider than the user's shoulder blades. This may allow the user to exercise different muscles during rowing activity. For example, a user can place his or her hands on the grip at different widths apart to exercise different muscles.

In some embodiments, the grip may be a modular grip or an adjustable grip. The grip may include a first part and a second part. The first cable can be connected to the first part and the second cable can be connected to the second part. No. One part and the second part may be selectively coupled or connected to each other. In some embodiments, the first part may be directly coupled or connected to the second part. In some embodiments, the grip accessory may be connected to one or both of the first or second portions. In some embodiments, the grip accessory may be a strut. A strut may be placed between the first and second sections to extend the width of the grip. This may allow the user to exercise different muscles by placing his or her hands in different positions on the grip.

In some embodiments, a pole grip accessory may be used to extend the grip to simulate kayak paddling. A dinghy paddle can have a wider handle than a rowing machine to simulate the action of a sliding dinghy. Dinghy paddles used on the water include a shaft that supports the paddle at either end. To propel the boat forward, the user lowers one end of the shaft and raises the other end of the shaft to position the paddle in the water in front of the user. The user can pull the paddle toward him or herself and pull the paddle out of the water. The user can then lower the second blade while raising the first blade to bring the second blade into contact with the water and pull the second blade back. Then, repeat this action indefinitely.

The handles can be used to simulate the paddling motion of a light boat. For example, the user can hold the grip and lower the first portion while raising the second portion. The user can then pull back on the first section (e.g., away from the flywheel, toward the sliding base). This action may extend the first cable without extending the second cable or while retracting the second cable. The user can then lower the second part while raising the first part. The user can then pull back on the second portion (e.g., away from the flywheel, toward the sliding base). This action can be performed without extending the first cable or while retracting the first cable. One cable extends the second cable simultaneously. In this manner, the user can simulate the movements and/or forces experienced when paddling on a dinghy using a dinghy oar.

While paddling, the user on the dinghy can remain in the same position relative to the body of the dinghy. In other words, the seats in a dinghy can be stationary or stationary. In certain embodiments, in a craft configuration as discussed herein, the sliding base may include a locking mechanism or base catch. The base buckle can lock the sliding base in place so that the base does not slide along the frame. Using the base buckle can help the user maintain stability and further simulate the paddling motion of a light boat, thus improving the user experience.

In some embodiments, the grip accessory may be a paddle shaft and handle, such as a canoe or dragon boat paddle shaft and handle, or other similar paddle shafts and handles. A canoe paddle has a single blade that extends into the water and has a bar on top for the user to grab onto. Only one oar extends into the water. To simulate the paddling motion of a canoe, the grip accessory can be attached to the first section only. The user can hold the grip assembly vertically or approximately vertically and perform canoe paddling motions through the grip by pushing the first portion downward and pulling the first portion rearward. Because the grip can only be connected to the first cable, this action can only extend the first cable. As can be appreciated, the accessory can similarly be connected to the second cable and simulate canoe paddling motion by extending the second cable. Modular or configurable grips that can be converted between rowing, dinghy and canoe configurations can increase the number of exercises that can be performed on the rowing machine, thereby increasing its versatility. More available Used sports can improve the user experience by reducing the number of sports equipment that users can use to perform these sports.

In some embodiments, the grip includes a first portion connected to a second portion at the grip junction. As described herein, the first and second portions may be selectively connected at the grip connection. Thus, the first part can be detached from the second part and connected again, depending on the sport performed, the grip accessories to be integrated with said grip, any other reasons for connection and their combinations.

The first part consists of the first grip. The first connecting arm can be connected to the first grip. The cable may be connected to the first portion at the first connecting arm. The second part includes the second grip. The second connecting arm can be connected to the second grip. The cable may be connected to the second part at the second connecting arm. Although the connecting arm is shown connected to and extending outside the grip, it should be understood that the cable could be connected directly to the grip.

The first part can be separated from the second part at the grip connection. In some embodiments, the first part has been separated from the second part at the grip connection. In some embodiments, the grip connection is an interlocking connection, such as a dovetail connection. The first portion includes a protrusion having at least one overhanging top portion. The second portion includes a recess including at least one complementary ceiling portion. When the protrusion is inserted into the recess, the protrusion and recess can interlock. The interlocking of the protrusions and recesses prevents separation of the first part from the second part. In certain embodiments, the interlocking connection between the protrusions and recesses may help prevent longitudinal removal, or removal parallel to the longitudinal axis of the grip.

In the embodiment shown, the grip connection includes a latch and a detent to prevent movement of the first part relative to the second part along the insertion axis of the projection into the recess. For example, the protrusions may include detents or recesses. The recess may include a latch. The latch may be configured to be inserted into the detent. In some embodiments, the latch may be biased outwardly by a spring or other resilient element. The protrusion can engage the latch when the protrusion is inserted into the recess. When the first part is fully connected to the second part, the latch can be inserted into the detent. The latch resists removal from the detent. This may help strengthen the grip connection, thereby preventing the first part from separating relative to the second part.

In some embodiments, the grip may have a magnetic grip connection. The magnetic grip connection may include a protruding magnet on a first portion of the grip, and a recessed magnet on a second portion of the grip. The protruding and recessed magnets may have complementary shapes. When connecting the first part to the second part, the protruding magnet can be magnetically connected to the female magnet. The magnetic connection pulls the first part to the second part and holds the two parts together.

In certain embodiments, the magnetic grip connection may include one or more alignment features. Alignment features help align the first part relative to the second part. In certain embodiments, the complementary shapes of the protruding and recessed magnets may be complementary. For example, the protruding magnets shown have an arcuate shape, while the recessed magnets have a complementary arcuate shape of similar size and shape. The complementary shapes allow the first portion to be oriented and aligned relative to the second portion when the protruding magnet is inserted into the concave magnet. This may help maintain alignment of the first connecting arm relative to the second connecting arm. first connecting arm and second connecting arm The alignment helps maintain constant pressure on the first and second sections while pulling on the rowing machine cable.

In some embodiments, a pedal for a rowing machine includes a platform. The toe strap is attached to the platform at the front end of the platform. The pedal also includes a plurality of heel buckles. In some embodiments, the plurality of heel buckles may be arranged longitudinally along the length of the platform. For example, the heel buckle shown is arranged in a line between the rear end of the platform and the toe strap. While using the pedals, the user can slide his or her feet, and more specifically, his or her toes into the toe straps. To insert his or her toes into the toe strap, the user slides his or her toes between the platform and the toe strap. Toe straps help the user's feet, especially the user's toes, stay connected to the platform.

In some embodiments, the toe strap may be a one size fits all toe strap. In some embodiments, the toe strap may be adjustable. For example, the toe strap may include a tightening mechanism such as buckles, Velcro straps, buttons, cables, knobs, any other tightening mechanism, and combinations thereof. In some embodiments, the toe strap may be formed from an elastic material and may be urged toward the user's foot. In some embodiments, the toe strap can be connected to a motor, and the motor can tighten the toe strap.

The heel buckle can be secured to the platform and biased above the platform. The heel buckle can be connected to the platform at the buckle connector. The heel buckle can extend toward the rear end of the platform through the extension portion. The heel buckle may extend rearwardly from the first buckle connector, loop through the extension portion, and extend rearwardly toward the second buckle connector.

In some embodiments, the extension may be biased upward and away from the platform. In some embodiments, the extension may be biased away from the platform such that there is space underneath the extension and between the platform. For example, the extension may be biased above the platform such that there is a gap below the extension and the platform.

When the user inserts his or her foot into the toe strap, the user may insert his or her foot in a forward direction (eg, from the rear end toward the front end). When inserting the foot, the user can use his or her heel to push down one or more heel buckles. For example, the user's heel may press down on the extension of the one or more heel buckles, thereby pressing the one or more heel buckles downward. This allows one or more heel buckle extensions to move toward the platform.

The plurality of heel buckles can be independently actuated. For example, each of the plurality of heel buckles may be connected to the platform via a separate buckle connector. Therefore, each heel buckle can be depressed and/or released independently of the remaining heel buckles. In certain embodiments, at least one rear heel buckle may remain in an undepressed state (eg, at least one heel buckle may remain in a neutral position). The at least one rear heel buckle may be the first undepressed heel buckle between the user's heel and rear end.

As the user pushes his or her foot forward and further into the toe strap, the user's heel may expose (eg, release) one or more heel buckle extensions. Because the extension is biased away from the platform, when the extension is exposed, the extension can be biased away from the platform. direction of movement. The newly exposed heel buckle can become the rear heel buckle. The user's heel can then be positioned between the toe strap and the rear extension of the heel buckle.

When the user has fully inserted his or her foot into the toe strap, the user's heel may be positioned between the at least one heel buckle extension and the toe strap. Because the extension extends above the platform, a portion of the extension may be located further above the user's heel. The extension may contact the user's heel and prevent rearward movement of the foot (eg, movement toward the rear end). In this way, the heel buckle helps the user keep the foot within the pedal. By preventing the user's feet from slipping during athletic activities, the user's stability during athletic activities can be increased.

It can be seen that the extension has a curved profile or shape. The curved profile or shape of the extension may help secure the user's foot to prevent backward movement of the foot (eg, toward the rear end). In certain embodiments, the curved profile or shape of the extension may help secure the user's foot against sideways movement of the foot (eg, lateral movement relative to the front and back ends). Combined with the user's toes being strapped in the toe strap, the user's feet can be securely connected or secured to the pedals during athletic activities. This improves the user's stability during athletic activities, thereby reducing the chance of injury due to the user's foot slipping off the platform.

In some embodiments, the user can pull the extension of the heel buckle upward to engage the user's heel. This may allow the user to place the extension in a comfortable position on his or her heel. For example, a user can place the extension over his or her Achilles tendon, foot The top of the calcaneus bone, the center of the heel bone, the bottom of the heel bone, or any other location on the user's heel. In this manner, the user can customize the comfort of the connection between the heel buckle and the user's foot.

In some embodiments, the pedal includes a plurality of heel buckles. For example, in the embodiment shown, there are seven heel buckles. Including multiple heel buckles may allow multiple users with different foot sizes to use the pedal. For example, a user with smaller feet may use his or her heel to engage the heel buckle closer to the front end of the platform. A user with larger feet can use his or her heel to engage the heel buckle closer to the rear end of the platform. Therefore, by including multiple heel buckles, multiple users with different sized feet can use the same pedal. This increases the versatility of the exercise device.

In some embodiments, the heel buckle may not have any adjustment mechanism. The length of the heel buckle may be fixed and there may not be any straps, tabs, buttons or other adjustment mechanisms to change the length of the heel buckle. The adjustability of the pedal to available foot sizes may be based, at least in part, on the number of heel buckles disposed between the front and rear ends of the platform.

In some embodiments, the heel buckle may be formed from an elastic material. For example, the heel buckle may be formed of elastically deformable plastic, rubber or other synthetic materials. When the heel buckle is secured to the user's foot, the heel buckle may deform to at least partially match the shape of the user's foot. Elastically deformable materials are generally softer and increase user comfort. In some embodiments, the elastically deformable material of the heel buckle can apply a retaining force to the user's foot. For example, toe straps can be used to prevent The user's foot moves in a forward direction (eg, toward the front). The elastically deformable heel buckle pushes the user's foot up against the toe strap to secure the foot snugly within the pedal.

In some embodiments, the elastically deformable material of the heel buckle can bias the extension over the platform. The heel buckle may have a neutral shape with the extension located above the platform. When the user's heel is pushed down against the extension, the heel buckle can elastically deform and be pushed against the platform. When the user's heel is removed from the extension, the elastically deformable material allows the heel buckle to return to a neutral position where the extension is above the platform.

The buckle connector can form a hinge between the platform and the extension. The heel buckle can rotate at the buckle connector when the user presses the extension toward the platform. In certain embodiments, the buckle connector may be elastically deformable. When the user presses the extension toward the platform, the buckle connector can elastically deform to allow movement of the extension. When the user's foot is removed from the extension, the buckle connector returns to its neutral shape, which moves the extension back to the neutral position.

In some embodiments, the buckle connector may be formed from a mechanical hinge. For example, the snap connector may include a spring hinge. For example, the buckle connector may include a coil spring, a leaf spring, a torsion spring, a clock spring, any other type of spring, and combinations thereof. Spring hinges can have a longer life, reducing the chance of the heel buckle breaking at one or both buckle connectors.

In some embodiments, the platform may include one or more depressions. The depression may be positioned beneath the heel buckle. The shape of the recess may be complementary to the heel buckle (eg, have the same shape and size). When the user pushes the heel buckle downward, the heel buckle can extend into the recess. When the heel buckle is pushed all the way to the platform, the heel buckle can be flush with the surface of the platform. Since the user is likely to push down on at least one heel buckle during the user's activities, pushing the heel buckle into the recess can provide the user with a flat or nearly flat surface for the user to push on while performing athletic activities. to help improve user comfort. This can improve the sports experience.

In some embodiments, the toe strap may extend above the platform at the toe strap height. In certain embodiments, the toe strap height may be configured to allow the user's toes to be secured to the platform. In certain embodiments, the toe strap height may be configured to secure the user's foot to the platform at the user's toes. In certain embodiments, the toe strap height may be configured to secure the user's foot to the platform at the user's arch. In certain embodiments, the toe strap height may be 2 cm, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm, or any value therebetween. As described herein, the toe strap may be adjustable such that the toe strap height is adjustable.

The heel buckle has a gap between the platform and the heel buckle. This gap can extend the buckle height. In some embodiments, the button height may be 0.5 cm, 1 cm, 1.5 cm, 2 cm, 2.5 cm, 3 cm, 3.5 cm, 4 cm, 4.5 cm, 5 cm, or any value therebetween. button part The height may be sized to allow the heel buckle to engage the user's foot at the heel of his or her foot.

In certain embodiments, the heel buckle has a buckle length, which may be the length of the heel buckle between the buckle connector and the extension. In certain embodiments, the button length may be 2 cm, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm, 12 cm, 14 cm, 16 cm, 18 cm, 20 cm, or any value therebetween. The buckle length is sized to fit the average user's foot. In some embodiments, each heel buckle may have the same buckle length. In some embodiments, different heel buckles may have different buckle lengths. For example, a heel buckle located closer to the toe strap may have a shorter buckle length than a heel buckle located further from the toe strap. This can help expand the range of user foot sizes that can comfortably use the pedals.

In some embodiments, the toe strap extends further above the platform than the heel buckle. When the user places his or her foot in the pedal, the user can pull the heel buckle upward to rest it comfortably on his or her foot.

In certain embodiments, a method for securing a user's foot to a rowing machine includes inserting the toes of the user's foot beneath a toe strap connected to a platform of a pedal to which the rowing machine is connected. The method may include depressing one or more heel buckles of a plurality of heel buckles connected to the platform. As described herein, the depression of one or more heel buckles is the result of, or is at least partially a function of, the user inserting his or her toes into the toe strap based on the size of the user's foot. result. In some embodiments, when the user slides his or her foot into position, one or more heel buckles are released (eg, moved to a neutral position). The method may also include securing the user's foot to the platform via a rear heel buckle. The rear heel buckle may be oriented behind the at least one depressed heel buckle. The rear heel buckle may be undepressed (eg, the heel buckle may be in a neutral position). During athletic activities, the rear heel buckle can contact the user's heel to secure the user's foot to the pedal.
