[0020] According to some embodiments, the device further comprises a protective member, the protective member being configured to reduce the likelihood of injury to individuals located adjacent the protective member. In some embodiments, the protective member is located along a rear of the device.

[0021] According to some embodiments, the resistance element remains in front of the user during use. In some embodiments, at least a part of the upper portion is configured to move behind the user during use. In some arrangements, the resistance element remains in front of the user during use, and wherein at least a part of the upper portion is configured to move behind the user during use.

[0022] According to some embodiments, a rowing device is provided that comprises an upper portion that is movable (e.g., slidably movable) relative to a lower or base portion and a seat assembly. As discussed herein, the seat assembly can be decoupled from the sliding movement of the upper portion during use. In some embodiments, the seat assembly may still move slightly (e.g., in an up and down manner, using a slight rocking or arced manner, in an angular or partly arcuate motion, etc.) when the upper portion moves relative to the lower portion. However, in such embodiments, the seat assembly, like the lower portion, does not slidably move relative to the upper portion, the lower or base portion or the ground.

[0023] According to some embodiments, the resistance element of the rowing device is positioned on the upper portion that is slidably movable relative to the lower or base portion, the ground and/or the seat assembly and the user positioned thereon. Tn some arrangements, the resistance element remains in front of the user at all times during use (c.g., despite the fact that the separation distance between the resistance element and the user, and thus, the seat assembly, varies during use). In some embodiments, at least a part of the upper portion of the device is configured to move behind the user, and thus the seat assembly, during use. As noted herein, because the moving element (e.g., the upper portion) moves behind the user and the seat assembly during the execution of a rowing stroke, one or more protective elements can be incorporated into the design of the rowing device. Such protective elements can help prevent or reduce the likelihood of impact, pinching and/or other types of injuries to the user and others that may be near the device.

[0024] According to some embodiments, the seat assembly is coupled (e.g., directly) to the lower or base portion of the rowing device. In some embodiments, the seat assembly is situated above the upper portion (e.g., the slidable or otherwise moving portion), at least in the location where the seat assembly is located. The seat assembly can be located toward the middle of the rowing device with respect to its longitudinal location (e.g., along the length of the device as defined by the longitudinal axis). In some embodiments, the seat and/or other portions of the seat assembly are located within the middle third of the device along the device’s longitudinal axis. In other embodiments, the seat and/or other portions of the seat assembly are located away from the longitudinal front and rear ends of the device. For example, the seat and/or other portions of the seat assembly are located away from the forward and rear longitudinal ends of the device, wherein the longitudinal ends are defined by the last 0% to 15% of the length within the device on either end of the device.

[0025] According to some embodiments, as discussed herein, the upper portion of the rowing device is configured to move relative to the lower or base portion using a first wheel, roller, rail and/or other movement system, while the upper portion also moves relative to the seat assembly using a second, separate wheel, roller, rail and/or other movement system.

[0026] According to some embodiments, the upper portion of the rowing device moves (e.g., slidably) as a unitary member, together with all the components of the upper portion, including, for example, the resistance element, the handle assembly and the footrest assembly, relative to the lower or base portion, the seat assembly and/or the ground. [0027] According to some embodiments, a rowing device for exercise comprises a scat assembly that moves in a non-slidablc manner (c.g., using an up-and-down, rocking, rotational, arcuate, etc.) such that the seat assembly mimics or re-creates, at least partially, movement of a seat in an actual rowing boat during use.

Detailed Description

[0039] The various features and concepts disclosed herein are well-suited for use in rowing machines or devices for exercise. Such exercise devices can be placed in a home, gymnasium or other indoor or outdoor space. However, such features and concepts may have application in devices, systems and methods outside the rowing device context, such as, for example, other types of exercise equipment and other types of mechanical devices and equipment generally.

[0040] The various embodiments disclosed herein offer one or more advantages and benefits. For example, the rowing device configurations provided herein: simplify the design of a rowing device by having key components moving in unison relative to a lower or base portion; maintain a stationary seat during use; provide a smaller footprint by allowing at least part of the moving portion to move behind the user during use; improves the safety of rowing devices; and the like.

[0041] According to some embodiments, one or more of the rowing machine or device embodiments disclosed herein comprise a lower or base portion that is slidably movable relative to an upper portion. The upper portion is configured to move relative to the lower portion. As discussed in greater detail herein, the relative movement between the upper and lower portions can be facilitated by the use of a rail or similar system. In some embodiments, the seat assembly is coupled to the base portion (e.g., the seat assembly is configured to not slide relative to the lower or base portion).

[0042] According to some embodiments, the seat assembly of the rowing device is configured to not slidably move relative to the lower or base portion (e.g., lower frame) of the device. In some embodiments, the seat assembly is coupled (e.g., directly or indirectly) to the frame or other component of the lower or base portion using a hinge or other movable joint. Therefore, although the seat portion of the seat assembly may move (e.g., slightly in an up-and- down and/or angular motion) relative to the lower or base portion, the seat assembly does not slide (e.g., along a rail or other system) during use.

[0043] In some arrangements, the seat assembly is secured to the lower or base portion along a middle or central portion of the lower or base portion (e.g., in a direction along the length of the device).

[0044] According to some embodiments, the rowing device comprises a flywheel or other resistance element. The resistance element can include any type, as desired or required by a particular design or configuration. For example, the resistance element can include, without limitation, a flywheel or other mechanical resistance element, a water or liquid resistance element, a wind-based or other type of hydraulic resistance element, a magnetic resistance element and/or the like. [0045] Tn some configurations, the resistance element, regardless of its type and other details, is configured to provide a desired resistance to the movement of one or more handles, straps, oar members or other components that are adapted to be moved (e.g., directly or indirectly) by the user. According to some embodiments, the resistance element is positioned on the upper portion of the rowing device. Thus, in arrangements where the upper portion is adapted to slidably move relative to a lower or base portion, the resistance element also moves (e.g., slidably) relative to the lower or base portion during use.

[0046] In some embodiments, the resistance element is configured to remain in front of the user during use (e.g., at all times). In some embodiments, the upper portion extends in the rearward direction such that at least a portion of it moves (e.g., slidably) behind the user during use. In one arrangement, a rear part of the upper portion is configured to extend both behind the user and in front of the user, and thus the seat of the seat assembly, during use (e.g., during a normal stroke).

[0047] According to some embodiments, one or more members (e.g., struts) of the upper portion are configured to move relative to at least a portion of the adjacent seat assembly using a separate rail or similar system. Therefore, in certain arrangements, the rowing device includes an upper portion that, during use, moves relative to the lower or base portion using a first rail or other movement system, and moves relative to the seat assembly using a second rail or other movement system.

[0048] In some arrangements, the upper portion of the device includes the resistance element and components that are coupled to the resistance element (e.g., straps, handles, oars, etc.) and the footrest. Accordingly, in several embodiments, the upper portion, together with the components or elements secured thereto, are configured to move (e.g., in unison or as a unitary portion) relative to the lower or base portion during use. As discussed in greater detail herein, such a “unitary” upper portion can be configured to slidably move relative to the lower or base portion and/or the seat assembly.

[0049] For any of the embodiments disclosed herein, the lower or base portion of the device can be configured to be stationary relative to the ground on which the device is positioned, even during use of the rowing device.

[0050] According to some configurations, the rowing device comprises a protective member to restrict access to moving portions of the device during use. For example, the device can include a protective member that extends along, toward and/or near the rear of the upper portion of the device that is configured to move (c.g., slidably) relative to the lower or base portion. The use of such protective members or configurations can help improve the safety of the device. For example, the protective members can prevent injuries to individuals who are positioned or move behind the device during use.

[0051] With reference to the perspective view of FIG. 1, in some embodiments, the rowing machine or device 10 comprises a lower or base portion 100 and an upper portion 200. According to some arrangements, the upper portion 200 is configured to move relative to the lower portion 100. As discussed in greater detail herein, the relative movement between the upper and lower portions can be facilitated by the use of a rail or similar system R. In some embodiments, the seat assembly is coupled to the base portion 100 (e.g., the seat assembly is configured to not slide relative to the lower or base portion).

[0052] Additional views of the rowing device 10 of FIG. 1 are provided in FIG. 3 (side view), FIG. 4 (top view), FIG. 5 (bottom view), FIG. 6 (rear view) and FIG. 7 (front view). Moreover, FIG. 2 is a schematic illustration of one embodiment of a rowing device.

[0053] As illustrated in FIGS. 1 and 2, the lower or base portion 100 of the rowing device 10 can be configured to be positioned along a ground surface (e.g., floor) and to be stationary relative to the ground surface during use. The base portion 100 can include one or more structural members 110 that form a frame. In the depicted arrangement, for example, such a frame can include elongated members (e.g., struts, tubular members, members having a different cross-sectional shape, etc.) 110 that are aligned along two or more direction or orientations (e.g., lengthwise and widthwise relative to the overall rowing device 10). However, in other embodiments, the structural members 110 can include a different configuration or design, as desired or required. For instance, the frame of the lower or base portion 100 can include structural members that are not elongated, such as, by way of example, plates, I-beams, channels and/or the like.

[0054] For any of the embodiments disclosed herein, the rowing device can include one or more elements or members 110 that help form the lower or base portion 100 (e.g., at least one or more frames of the base portion). Such elements or members 110 can include a rigid or semi-rigid construction and design that are configured to withstand the forces, moments, wear-and-tear and/or other potentially-damaging circumstances created by use of the device. Tn some arrangements, the structural elements 1 10 and/or any other portion of the lower portion 100 comprises one or more metals, alloys, thermoplastics and/or other materials (c.g., steel, iron, composites, etc.).

[0055] As shown in FIGS. 1 and 3, the rowing device 10 can include a plurality of foot pads 120 that are positioned under selected portions of the structural elements 110 and that contact the ground surface. Such foot pads can be at least partially flexible or compressible, which can assist in stabilizing the rowing device 10 relative to the ground surface. In some embodiments, the foot pads 120 can be configured to be adjusted (e.g., to assist with the proper balancing and positioning of the device along the ground).

[0056] With continued reference to FIGS. 1 to 4, the upper portion 200 of the rowing device 10 can be configured to slide or otherwise move relative to the lower or base portion 100 along the longitudinal axis L of the device. In the illustrated embodiment, the rowing device 10 comprises a rail system R to facilitate the movement of the upper portion 200 relative to the stationary lower or base portion 100. As shown, the rail system R can include a plurality of wheels 206 extending from the lower end of a one or more structural members or elements 202 that help form the upper portion 200.

[0057] In the illustrated arrangement, the upper portion 200 comprises a total of four wheels 206, with two wheels 206 located along the front of the upper portion 200 and two wheels 206 located along the rear. In other embodiments, however, more or fewer than four wheels can be used (e.g., 1, 2, 3, 5, 6, 7, 8, 9, 10, more than 10, etc.), as desired or required by a particular application or design. In some embodiments, the wheels 206 are sized, spaced and otherwise configured to at least partially couple with, rest on and/or otherwise mate with corresponding features, components and/or other surfaces of the lower or base portion 100. In the illustrated embodiment, the wheels 206 of the upper portion 200 include track wheel or groove wheel designs. For example, the wheels 206 can include one or more grooves or other recesses, one or more flanges (e.g., on or along one lateral end of the wheel, on or along both ends of the wheel, etc.) and/or any other features (e.g., protrusions, recesses, etc.) that help guide the wheel relative to a corresponding feature or portion of the lower or base portion 100. In some embodiments, the wheels 206 of the upper portion 200 include U-grooved or V- grooved wheels. The groove(s) of the wheels 206 can be shaped, sized and otherwise configured to at least partially mate and/or align with the corresponding member, feature and/or other surface of the lower or base portion 100 along which the wheels 206 will move when the rowing device 10 is in use. By way of example, the groove of the wheels can include a central rounded groove having a radius of curvature that matches or substantially matches and/or otherwise mates with, at least in part, the rounded or curved upper surface of the circular elongated members 110 included in the base portion 100.

[0058] In alternative embodiments, the relative movement between the upper portion 200 and the lower portion 100 can be replaced and/or supplemented by a different system. For instance, in some arrangements, the wheels can include a protruding portion that is configured to mate with a corresponding groove or recess of the elongated members 110 of the lower portion 100. In other embodiments, the wheels can be included on the lower portion instead of the upper portion, thereby reversing the configuration illustrated in FIG. 1. In yet other embodiments, one or more wheels can include one or more flanges or other features that facilitate the interaction between the wheel and a corresponding portion of the opposite portion 100, 200, as desired or required.

[0059] According to some embodiments, the wheels and the corresponding components, features, elements or surfaces along which the wheels are configured to move, a rail system and/or any other system configured to facilitate relative movement between the lower and upper portions 100, 200 are configured to prevent or reduce the likelihood of relative separation between the different mating or contacting components or surfaces. For instance, the rowing device 10 can include one or more locking or anti-separation features (e.g., channels, locks, clips, housings, etc.) that reduce the likelihood of undesirable separation or detachment while the upper portion 200 is moving relative to the lower or base portion 100 during use. However, in other arrangements, such features are not included.

[0060] As shown in the illustrated embodiments, the upper portion 200 can include the resistance element 210, the footrest assembly 260, which may comprise individual footrests 262, the handle assembly 220 that is operatively (e.g., mechanically) coupled to the resistance element 210 and/or any other components (e.g., straps or other components coupled to, directly or indirectly, to the resistance element and/or the handle assembly, displays, monitors or other visual components, speakers or other audible components, sensors, power supply components, etc.). In some arrangements, all such components and/or features are configured to move in unison or as a unitary or monolithic component during use (e.g., relative to the lower or base portion 100 and the ground surface). According to some embodiments, the seat assembly 50 extends above the top of the upper portion 200, at least in certain locations along the length of the device 10 and does not slide or is not otherwise laterally displaced relative to the lower portion 100 and the ground on which the rowing device 10 is positioned. In some embodiments, the seat assembly 50 is coupled to (e.g., directly or indirectly, rigidly or rotatably/movably, etc.) at least a portion of the lower or base portion 100. In some embodiments, the seat assembly 50 is configured to not slide relative to the lower or base portion 100 during use.

[0061] With reference to FIGS. 2 and 3, in some embodiments, the seat assembly 50 is coupled to the lower or base portion 100. As discussed herein, although the seat assembly 50 may still move slightly during use of the rowing device 10, the seat assembly 50 is configured to not slide relative to the lower portion 100. Therefore, the seat assembly 50 can be slidably decoupled from the upper portion 200 of the device 10. In the schematic of FIG. 2, the seat assembly 50 is connected to the lower or base portion 100 using a connecting member or system 40. Accordingly, in some embodiments, the upper portion 200 of the device can be configured to slidably move relative to the lower portion 100 and the seat assembly 50. In some embodiments, the seat assembly is slidably decoupled from the upper portion 200 and all the components and elements positioned on the upper portion 200, including, for example, the resistance element 210, the handle assembly 220 and the footrest assembly 260.

[0062] As illustrated in FIGS. 3 and 8, in some embodiments, seat assembly 50 can include a seat portion 52 on which users sit when using the device 10. A seat harness 54 can be situated underneath the seat portion 52 and provide a base to which the seat portion 52 can be secured (e.g., directly or indirectly). With reference to the partial perspective view of FIG. 8, the seat harness 54 can include one or more rollers, wheels or other elements or components 60 that are configured to move (e.g., rotate) when one or more structural components or other elements 202 of the upper portion 200 are slidably moved relative to the lower or base portion 100. Accordingly, in some arrangements, when the upper portion 200 is slidably moved relative to the lower or base portion 100, not only are the wheels 206 moved relative to the corresponding mating or contacting components 110 of the lower portion 100 (e.g., along the lower end of the upper portion 200), but another portion of the upper portion (e.g., a structural element or component 202 of the upper portion) is moved relative to one or more components, portions and/or surfaces (e.g., wheels, rollers or other movable members 60) of the seat assembly 50. Thus, the upper portion 200 can be configured to move relative to both the lower portion 100 and the seat assembly 50 using separate rail or other movable systems. In some embodiments, the seat assembly 50 can include rollers, wheels and/or other movable members 60 along the bottom and/or the top of the adjacent elements, components and/or parts of the upper portion 200. For instance, the seat assembly 50 illustrated in FIG. 8 can include one, two or more rollers or other movable members 60 along the bottom of member 202 of the upper portion 200 and one, two or more rollers other movable members 60 (not shown) along the top of member 202, as desired or required.

[0063] With continued reference to FIG. 8, the connecting member or system 40 can comprise one or more struts or other structural members 48 that extend from one or more components of the base portion 100 to one or more components of the seat assembly 50. The connecting member or system 40 can include upper and/or lower hinges, joints and/or any other movable connections 42, 44 at, along or near its upper and/or lower ends. As illustrated in the depicted embodiment, the top or upper end of the structural component or member 48 of the connecting system 40 can be connected to the harness or other base portion 54 of the seat assembly 50 using a hinge, joint or other movable connection 42. The same or similar movable connection 44 can be used to connect the bottom end of the structural component 48 to the lower or base portion 100 of the rowing device 10.

[0064] In such embodiments, such hinges, joints or other movable connections 42, 44 can help accommodate for any natural movement of the seat assembly 50 as the upper portion 200 slidably moves relative to the lower portion 100 and the seat assembly 50. For example, movement of the seat 52 and other portions of the seat assembly 50 during use of the rowing device 10 (e.g., as a result of movement of the upper portion 200 relative to the lower or base portion 100 and the seat assembly 50) can be a reciprocating up and down movement, an angular movement (e.g., along an arc or other curved pattern) and/or the like. This is illustrated by the arrangement of FIG. 9, wherein the varying position of the seat assembly 50, 50' can be seen as a consequence of movement of the resistance element 210, 210' during use of the rowing device 10. For example, the seat assembly 50 is shown in solid line when the resistance element 210 is in the rearwardly-retracted orientation (e.g., when the resistance element 210 is located closer to the seat assembly 50). As the resistance element 210' (and the rest of the components, members, elements, etc. that are positioned on and/or incorporated in to the upper portion 200) is move forwardly (e.g., away from the scat assembly), the scat assembly 50' can be configured to move in the forward and/or upward direction (e.g., slightly in the forward and/or upward direction). This is represented by the seat assembly 50' that is illustrated in broken line in FIG. 9. Therefore, in some embodiments, although the seat assembly 50 is not configured to slidably move relative to the lower or base portion 100 (and the ground), the seat assembly 50 can move in other manners during use. Such movement can include, for instance, at least partial movement using an up and down movement, along a rotational or turning point or points, in a rocking motion, along an arc and/or the like.

[0065] As shown in FIG. 9, the upper portion 200 (and thus, the resistance element, the handle assembly, the footrest assembly and any other components or elements positioned on or incorporated into the upper portion 200) can move by a distance A from the rear to the forward positions during use. In some embodiments, this movement distance A can be between 1 and 5 feet or 0.3 and 1.5 meters (e.g., 1 to 5, 2 to 4, 2 to 5, 1 to 3, 1 to 4, 1 to 2, 2 to 3, 3 to 4, 4 to 5 feet, lengths between the foregoing ranges or values, etc.). In one embodiment, such movement distance A is for a rowing device that has a length L between 4 and 12 feet. In some embodiments, the ratio of length L of the device (e.g., in the longitudinal direction) to the movement distance A of the upper portion 200 is between 2 and 5 (e.g., 2, 3, 4, 5, 2 to 3, 3 to 4, 4 to 5, ratios between the foregoing values and ranges, etc.). In other embodiments, however, such a ratio is lower than 2 or greater than 5, as desired or required.

[0066] As illustrated in FIGS. 3 and 9, in some arrangements, one or more components 202 of the upper portion 200 that are configured to move adjacent the seat assembly 50 can be non-horizontal. For example, structural component 202 that is adjacent to the seat assembly can be angled relative to the horizontal plane (e.g., the ground surface, at least part of the lower portion or base 100, etc.). In FIG. 3, the structural component 202 is aligned with a line or plane indicated by broken line A, whereas the true horizontal line or plane is depicted by broken line H. The same angle is illustrated in FIG. 9; however, with reference to a horizontal line of the lower portion 100. Such an angle 0 can vary between 0 to 25 degrees (e.g., 0-1, 1-2, 0-2, 0-3, 2-3, 3-4, 4-5, 5-6, 6-7, 7-8, 8-9, 9-10, 10-15, 15-20, 20-25, 0-5, 5-10, 0- 10 degrees, 1 degree, 2 degrees, 3 degrees, angles between the foregoing values and ranges, etc.). In some embodiments, the row device 10 is designed and otherwise configured to permit the angle 0 to be adjusted (e.g., by a user, by the manufacturer, etc.), as desired or required. Tn some embodiments, however, the structural componcnt(s) 202 of the upper portion 200 that arc adjacent the seat assembly 50 are horizontal (e.g., relative to ground).

[0067] In some embodiments, the undulating, up and down, angular and/or other movement of the seat assembly 50 during use can be created and/or can be more pronounced when the structural component(s) of the upper portion 200 that is/are located adjacent the seat assembly 50 is/are angled relative to horizontal. For example, in the illustrated arrangements, the angle 0 along the element(s), member(s) and/or other parts of the upper portion 200 that move (e.g., slide) relative to one or more portions of the seat assembly 50 can help create the rotational, rocking, arcuate, up-and-down and/or other movement (e.g., non-sliding or non- slidable movement) of the seat assembly when the rowing device 10 is being used. However, in other embodiments, the seat assembly 50 is configured to remain stationary during use of the rowing device 10.

[0068] In some embodiments, a seat assembly 50 is configured to move (e.g., non- slidably relative to the lower portion or the ground) using an up-and-down, rocking, rotational, arcuate and/or similar movement (e.g., as depicted in FIG. 9) to mimic, at least partially, the natural movement of a seat in an actual rowing boat or similar vehicle. Therefore, in some arrangements, the rowing device 10 can create a more realistic experience as it pertains to performing a rowing stroke or motion.

[0069] According to certain arrangements, movement (e.g., slidable movement) of the upper portion 200 relative to the lower or base portion 100 can be limited in the forward and/or rear direction. Such movement limitation can be accomplished using stops or other mechanical features that restrict movement of the upper portion within a desired range.

[0070] With continued reference to FIG. 8, the underside of the structural component or element that is configured to move adjacent the seat assembly 50 during use can include forward and rear stops or other motion limiting components, elements or features 66, 68. Thus, during use, when the upper portion 200 is moving in a forward direction (e.g., in a direction generally represented by broken arrow line MF in the schematic of FIG. 2), rear stop or limiter 68 will contact a portion of the seat assembly (e.g., roller or wheel 60), thereby preventing further forward movement of the upper portion 100 relative to the lower or base portion 200. [0071] Likewise, during use, when the upper portion 200 is moving in a rearward direction (c.g., in a direction generally represented by broken arrow line MR in the schematic of FIG. 2), forward stop or limiter 66 will contact a portion of the seat assembly (e.g., roller or wheel 60), thereby preventing further rearward movement of the upper portion 100 relative to the lower or base portion 200.

[0072] In other embodiments, alternative methods of limiting forward and/or rearward movement of the upper portion 200 relative to the lower or base portion 100 can be incorporated into the rowing device, as desired or required.

[0073] For any of the rowing machine or device embodiments disclosed herein or equivalents thereof, the rowing device can comprise any type of flywheel or other resistance element 200, as desired or required. By way of example, the resistance element can include, without limitation, a flywheel or other mechanical resistance element, a water or liquid resistance element, a wind-based or other type of hydraulic resistance element, a magnetic resistance element and/or the like.

[0074] The level of resistance provided by the resistance element during use can be fixed or adjustable, as desired or required. The rowing device 10 of FIG. 1 includes a knob or other adjustable component 214 to permit a user to vary the level of resistance generated by the resistance element 210 and associated with movement of the handlebar or similar grasping assembly 220.

[0075] The component or portion of the rowing device that the user grasps and manipulates while using the device can be customized or otherwise varied to satisfy certain design criteria. For example, the device 10 can include a handle assembly 220. In the depicted embodiments, the handle assembly 220 includes a single bar or elongated member that is shaped, sized and otherwise adapted to be grasped and held by the user during use. However, in alternative arrangements, the handle assembly 220 can include two separate handles or other portions that are configured to be grasped and held by the user. In other embodiments, the rowing device 10 comprises oars or similar members that are configured to be grasped by the user. Regardless of the exact type of handles or other components of the rowing device that are intended to be handled by the user, such assemblies 220 can be operatively coupled to the resistance element 210 to provide a desired level of resistance related to manipulation of the assemblies. [0076] According to some embodiments, as depicted schematically in FIG. 2, the handle or other grasping assembly 220 of the rowing device 10 can be coupled (c.g., operatively, mechanically, etc.) to the resistance element 210 using one or more straps, bands, connecting struts or members and/or the like 224, as desired or required. Whether such interconnecting or coupling members or features 224 are required or desired can depend on, at least in part, the type of resistance element 210 used in the rowing device.

[0077] With continued reference to the schematic of FIG. 2 and discussed in greater detail herein, the rowing device or rower 10 can be configured such that an upper portion 200 moves (e.g., slidably) relative to a lower or base portion 100 and the seat assembly 50 during use. In some embodiments, a user (not shown in FIG. 2) is seated on the seat assembly facing the resistance element 210. Users can position their feet on the footrest assembly 260. For any of the arrangements of the rowing device 10 disclosed herein or equivalents thereof, the footrest assembly 260 can include separate footrest elements 262 for the user’s left and right feet. However, in other configurations, the footrest assembly 260 comprises only a single footrest element adapted to accommodate both of the user’s feet. The footrest assembly 260, regardless of its exact type, orientation and other details can include one or more straps or similar members that help maintain the user’s feet on the footrest assembly 260 during use.

[0078] Once the user is seated on the seat assembly and has secured their feet on the footrest assembly 260, the user can grasp the handle assembly 220 can begin using the device. In some embodiments, users pull the handle assembly 220 toward themselves (e.g., against the resistance generated by the resistance element 210). During such an action, users can push their legs forward, causing the upper portion 200 to move forward relative to the lower portion 100, the seat assembly 50 and the ground.

[0079] Further, in some arrangements, subsequently, when users extend their arms (e.g., allowing the handle assembly 220 to retract or move toward the resistance element 210), their legs bend and the upper portion 200 moves in a rearward direction relative to the lower portion 100. Such a stroke or motion can be repeated over a period of time during an exercise session. Other types of strokes or motions can be conducted using the rowing devices described herein or other rowing devices having one or more of the features disclosed herein, as desired or required. [0080] Tn some embodiments, the rowing device 10 can be placed in a vertical orientation (not illustrated in the accompanying drawings) to reduce its storage footprint when not being used. For example, the device 10 can be tilted upwardly, e.g., rotated 90 degrees (or substantially 90 degrees) relative to the orientation depicted in FIG. 1, for storage. In some embodiments, the rowing device 10 comprises one or more components or other features 216 that assist with placement of the device 10 in a vertical or upwardly tilted orientation. For example, one or more footpads or similar elements 216 can be positioned along the portion or portions of the device that may contact the ground when re-orienting the device for storage. In the embodiment of FIG. 1, for instance, the rowing device 10 is configured to be tilted upwardly, e.g., rotated 90 degrees or substantially 90 degrees (e.g., counterclockwise as illustrated in FIG. 1), to place the device 10 in a vertical position.

[0081] In some embodiments, the upper portion 200 can be separated from the lower portion 100 to facilitate storage, transport, servicing, repairs and/or the like. However, in other arrangements, the device 10 is configured such that upper portion 200 is not separable from the lower or base portion 100, as desired or required.

[0082] According to some embodiments, the rowing device 10 (e.g., as a whole, one or more components of the device 10, such as, the upper portion 200, the lower portion 100, etc.) are configured to be folded or moved into a retracted orientation, position or profile. For example, at least one component or area of the rowing device 10 can include a hinge, a telescoping design and/or other movable components or portions that permit a user to reconfigure the device 10 between an extended orientation or shape (for use) and a storage or other smaller footprint orientation or shape (when the device is not being used). Accordingly, such embodiments can make it easier to at least partially hide the device and/or otherwise move the device out of a particular area for space-saving purposes.

[0083] Any of the rowing devices disclosed herein or equivalents thereof can include additional components, devices, systems, elements and/or the like. By way of example, as illustrated in FIG. 1, the rowing device 10 can include a display or other output 240 (e.g., touchscreen, internal or external monitor or other display, etc.), speakers or other audible outputs, haptic or other outputs, other sensory outputs, sensors or monitors (e.g., temperature sensor, humidity sensor, motion sensor, movement sensors, weight sensors, heartrate monitors, etc.) and/or the like, as desired or required. Further, the rowing device 10 can include one or more processors, batteries and/or power supplies, wireless communication technologies (e.g., Bluetooth, Wi-Fi and/or other components) and/or the like.

[0084] In some embodiments, as illustrated herein, the rowing device 10 comprises one or more safety components. For example, as depicted in FIG. 1, a protective member 170 can be positioned along the rear of the device. In the illustrated embodiments, the protective member 170 is secured to the lower portion and is configured to remain stationary during use. However, in other embodiments, at least a portion of the protective member 170 can be secured to the upper portion 200 and/or can be configured to at least partially move when the rowing device 10 is being used.

[0085] With continued reference to FIG. 1, the protective member 170 can include one, two or more structural components that prevent bystanders or others who are in close proximity to the device 10 from getting injured by the moving portions (e.g., the upper portion 200) of the rowing device 10. As shown, the protective member can extend from the rear portion of the device 10 and extend forward in the direction of the seat assembly 50 and the resistance element 210. In some arrangements, the protective member extends sufficiency forward so as to cover an entire length of possible movement of the upper portion 200. In several embodiments, as shown, the protective member can include one or more solid components (e.g., a solid panel) 172 to further prevent or restrict access to moving components of the device.

[0086] According to some embodiments, a rowing device 10 is provided that comprises an upper portion 200 that is movable (e.g., slidably movable) relative to a lower or base portion 100 and a seat assembly 50. As discussed, the seat assembly 50 can be decoupled from the sliding movement of the upper portion 200 during use. In some embodiments, the seat assembly may still move slightly (e.g., in an up and down manner, using a slight rocking or arced manner, in an angular or partly arcuate motion, etc.) when the upper portion moves relative to the lower portion. However, in such embodiments, the seat assembly, like the lower portion, does not slidably move relative to the upper portion 200, the lower or base portion 100 or the ground.

[0087] According to some embodiments, the resistance element 210 of the rowing device 10 is positioned on the upper portion 200 that is slidably movable relative to the lower or base portion 100, the ground and/or the seat assembly 50 and the user positioned thereon. In some arrangements, the resistance element 210 remains in front of the user at all times during use (c.g., despite the fact that the separation distance between the resistance element 210 and the user, and thus, the seat assembly 50, varies during use). In some embodiments, at least a part of the upper portion 200 of the device 10 is configured to move behind the user, and thus the seat assembly 50, during use. As noted herein, because tire moving element (e.g., the upper portion 200) moves behind the user and the seat assembly 50 during the execution of a rowing stroke, one or more protective elements 170 can be incorporated into the design of the rowing device 10. Such protective elements 170 can help prevent or reduce the likelihood of impact, pinching and/or other types of injuries to the user and others that may be near the device.

[0088] According to some embodiments, the seat assembly is coupled (e.g., directly) to the lower or base portion 100 of the rowing device 10. In some embodiments, the seat assembly 50 is situated above the upper portion (e.g., the slidable or otherwise moving portion) 200, at least in the location where the seat assembly 50 is located. The seat assembly 50 can be located toward the middle of the rowing device with respect to its longitudinal location (e.g., along the length of the device as defined by the longitudinal axis LA). In some embodiments, the seat 52 and/or other portions of the seat assembly 50 are located within the middle third of the device along the device’s longitudinal axis. In other embodiments, the seat 52 and/or other portions of the seat assembly 50 are located away from the longitudinal front and rear ends of the device. For example, the seat 52 and/or other portions of the seat assembly 50 are located away from the forward and rear longitudinal ends of the device, wherein the longitudinal ends are defined by the last 0% to 15% of the length within the device on either end of the device.

[0089] By way of example, as illustrated in FIGS. 9 and 10, the seat assembly 50 can be positioned a distance SR from the rear end (e.g., along a longitudinal direction) of the device 10. Likewise, the seat assembly 50 can be positioned a distance SF from the front end (e.g., along a longitudinal direction) of the device 10. In some embodiments, each of these distances SR, SF can be greater than 15% (e.g., at least 15%, 20%, 25%, 30%, percentages between the foregoing, greater than 15%, etc.) of the overall length L of the rowing device 10. Accordingly, in some embodiments, the seat assembly is not positioned near or along the rear end and is not positioned near or along the forward end of the device 10.

[0090] According to some embodiments, as illustrated in FIG. 10, the length L of the device (e.g., from the rear end to the front end along the longitudinal axis LA) is between 4 and 12 feet or 1 .2 and 3.7 meters (e.g., 6 to 12, 6 to 10, 8 to 10, 4 to 5, 5 to 6, 6 to 7, 7 to 8, 8 to 9, 9 to 10, 10 to 12 feet, lengths between the foregoing ranges or values, etc.). Further, the width W of the device (e.g., as defined by the lateral ends of the elements or members 110 of the lower or base portion 100, in a direction perpendicular to the longitudinal axis LA) is between 1 and 5 feet or 0.3 and 1.5 meters (e.g., 1 to 5, 2 to 4, 2 to 5, 1 to 3, 1 to 4, 1 to 2, 2 to 3, 3 to 4, 4 to 5 feet, lengths between the foregoing ranges or values, etc.). Also, the height H of the device (e.g., as defined by the distance between the ground surface on which the device 10 is configured to rest and the top of the resistance element 210 as shown in FIG. 9) is between 1 and 5 feet or 0.3 and 1.5 meters (e.g., 1 to 5, 2 to 4, 2 to 5, 1 to 3, 1 to 4, 1 to 2, 2 to 3, 3 to 4, 4 to 5 feet, lengths between the foregoing ranges or values, etc.). In one embodiment, the length L, width W and height H of the device 10 are 8 to 9 feet, 1.5 to 2.5 feet and 2 and 3 feet, respectively. However, as noted above, the device 10 can have different dimensions, as required or desired.

[0091] According to some embodiments, as discussed herein, the upper portion 200 of the rowing device 10 is configured to move relative to the lower or base portion 100 using a first wheel, roller, rail and/or other movement system, while the upper portion 200 also moves relative to the seat assembly 50 using a second, separate wheel, roller, rail and/or other movement system.

[0092] According to some embodiments, the upper portion 200 of the rowing device 10 moves (e.g., slidably) as a unitary member, together with all the components of the upper portion, including, for example, the resistance element, the handle assembly and the footrest assembly, relative to the lower or base portion 100, the seat assembly 50 and/or the ground. Such unitary movement is schematically represented by the items included in box U of FIG. 9. As shown and discussed in greater detail herein, elements and/or components positioned on and/or incorporated in the upper portion 200, including, for example, the resistance element 210, the handle or grasping assembly 220 and the footrest assembly 260 (to name just a few), can be configured to move (e.g., slidably) relative to the lower or base portion 100. Such movement can include slidable movement of the upper portion 200 (and thus, the components secured to or incorporated therewith) relative to the lower or base portion 100 along the longitudinal axis LA. The slidable movement (e.g., represented by arrows LM on FIG. 9) can include both forward and rear movement during the execution of a stroke or cycle. [0093] With continued reference to the side view of FTG. 9, in some arrangements during use of the rowing device 10, a user (not shown) is seated in the scat assembly 50. The user’s feet can be positioned on (e.g., removably secured to) the foot assembly 240, and the user can grasp the handle assembly 220 before beginning the rowing stroke or motion for a desired period of time. During such a stroke, cycle or other motion, the user stays stationary or substantially stationary (e.g., slidably) relative to the lower or base portion 100, and thus, the ground surface. As discussed above, the seat assembly 50 can include one or more joints or other movably portions, components or elements that permits the seat assembly to rock, move up and down, rotate along one or more pivot points, move along an arc or angle and/or the like. This is illustrated by the two representations of the seat assembly 50, 50' in FIG. 9.

[0094] As shown in FIG. 9, in some embodiments, when the resistance element 210 is in the retracted (e.g., rearwardly retracted) orientation, the is seat assembly 50 is positioned vertically lower and longitudinally rearward of the position of the seat assembly 50' when the resistance 210' is move forward. Therefore, in some embodiments, although the seat assembly 50 is not configured to slidably move relative to the lower or base portion 100 (and the ground) during use, the seat assembly 50 can move in other manners during use. Such movement can include, at least partially, an up and down movement, movement along a rotational or turning point or points, rocking motion, motion along an arc and/or the like.
