[0037] In the following description of various examples and components of the present disclosure, reference is made to the accompanying drawings, which form a part of the present disclosure, in which various example structures and environments in which various aspects of the present disclosure may be implemented are shown by way of illustration. It is understood that other structures and environments may be used without departing from the scope of the present disclosure, and that structural and functional modifications may be made to the specifically described structures and methods.

[0038] Additionally, although the terms "top", "base", "bottom", "side", etc. may be used in this specification to describe various exemplary features and elements, these terms are used herein for convenience, for example, based on the example orientations shown in the figures and / or orientations in typical use. Nothing in this specification should be construed as requiring a structure to have a specific three-dimensional or spatial orientation in order to fall within the scope of the claims.

[0039] As used herein, the term "substantially parallel" may be defined as two portions (i.e., edges, surfaces, or center lines) being within + / - 10 degrees of each other. As used herein, the term "substantially perpendicular" may be defined as two portions (i.e., edges, surfaces, or center lines) being within + / - 10 degrees of being orthogonal (i.e., 90 degrees) to each other.

[0040] As used herein, the term “connected” may be defined to include directly connected components (components contacting each other) and indirectly connected components (components connected via one or more intermediate components).

[0041] The present disclosure generally relates to a rowing machine having a use position that allows a user to perform a rowing exercise and a storage position, wherein the use position allows a user to perform a rowing exercise and the storage position configures the rowing machine to have a smaller footprint and occupy less surface area on a surface on which it is supported. In addition, when the rowing machine is in the storage position, the user cannot perform a rowing exercise.

[0042] Figure 1-Figure 3An exemplary rowing machine 100 is shown in a use position. Rowing machine 100 may include: a first frame member 110; a second frame member 130 pivotally connected to first frame member 110; a resistance device 150 connected to first frame member 110; a connection member 170 operably connecting resistance device 150 to an exercise handle 180 configured to be engaged by a user and receive force from the user; a seat 190 slidably engaged with second frame member 130; and a pair of footrests 320 configured to position and secure the user's feet when rowing machine 100 is in use. Front support 121 may extend from first frame member 110, and may be positioned to support the user's feet. Figure 1-3 In an embodiment, the front support includes a pair of legs 126, wherein each leg 126 of the pair of legs 126 includes a wheel 128. In addition, a rear support 148 can extend from the second frame member 130. The pair of legs 126 (or other front supports) and rear supports 148 can support the rowing machine 100 on a support surface (e.g., a floor, ground, platform, or other surface known to those skilled in the art) without other ground-engaging support structures between the front and rear supports. Each leg 126 is connected to the first frame member 110 by a single connection structure and is oriented at an acute angle (e.g., between 45° and 75°) to each other.

[0043] The rowing machine 100 is movable (e.g., pivotable) between a use position and a storage position and includes a locking assembly 200 movable between a locked position and an unlocked position. When the locking assembly 200 is in the locked position, the locking assembly 200 rotationally fixes or secures the first frame member 110 relative to the second frame member 130 to position or secure the rowing machine 100 in the use position. When the locking assembly 200 is in the unlocked position, the second frame member 130 can be rotated relative to and toward the first frame member 110 to move the rowing machine 100 from the use position to the storage position. When the locking assembly 200 is in the unlocked position, a user can move the rowing machine 100 from the use position to the storage position by pulling upward on a handle 240 located on the first frame member 110. Figure 4 and Figure 5 The process of rowing machine 100 transitioning from the use position to the storage position is shown. Figure 6 The rowing machine 100 is shown in a storage position in which the clamp 139 engages the rib 127 extending between the pair of legs 126 to lock the rowing machine 100 in the storage position.

[0044] The first frame member 110 may include a first end 112, a second end 114 opposite the first end 112, and a first frame body 116 extending between the first end 112 and the second end 114. The first frame body 116 may include a top surface 118, a bottom surface 120 opposite the top surface 118, and a pair of side surfaces 122 extending between the top surface 118 and the bottom surface 120 to form an interior cavity 124 within the first frame member 110. The top surface 118 and the bottom surface 120 may be substantially parallel to each other. Similarly, the pair of side surfaces 122 may also be substantially parallel to each other.

[0045] The second frame member 130 may include a first end 132, a second end 134 opposite the first end 132, and a second frame body 136 extending between the first end 132 and the second end 134. The second frame body 136 may include a top surface 138, a bottom surface 140 opposite the top surface 138, and a pair of side surfaces 142 extending between the top surface 138 and the bottom surface 140 to form an interior cavity 144 within the second frame member 130. The top surface 138 and the bottom surface 140 may be substantially parallel to each other. Similarly, the pair of side surfaces 142 may also be substantially parallel to each other. The first end 132 of the second frame member 130 may be pivotally connected to the second end 114 of the first frame member 110. The first end 132 of the second frame member 130 may be connected to a circular hub 145 having a substantially curved surface 146, wherein the curved surface 146 may have a constant radius. When moving from the use position to the storage position, second frame member 130 may be rotated about pivot 149 such that second end 134 of second frame member 130 moves toward first end 112 of first frame member 110. Rowing machine 100 may be positioned in the storage position by pivoting second frame member 130 relative to first frame member 110 such that second end 134 of second frame member 130 and first end 112 of first frame member 110 are positioned at the same end of rowing machine 100, and rowing machine 100 is thus positioned in an inverted V-shape, such as Figure 6 As the second frame member 130 rotates toward the first frame member 110 , the curved surface 146 may prevent any injury to the user by eliminating any sharp surfaces or pinch points at the joint between the first frame member 110 and the second frame member 130 .

[0046] The rowing machine 100 may have Figure 1 The use positions shown and Figure 6When rowing machine 100 is in the use position, second frame member 130 may be in a substantially parallel orientation with respect to the support surface, or as another way of describing the relationship between first frame member 110 and second frame member 130 in the use position, top surface 118 of first frame member 110 may form an obtuse angle (i.e., between 90° and 180°) with top surface 138 of second frame member 130. In some examples, the obtuse angle between top surface 118 and top surface 138 may be between 100 degrees and 135 degrees. Conversely, when rowing machine 100 is in the storage position, second frame member 130 may be in a substantially perpendicular orientation with respect to the ground, or as another way of describing the relationship between first frame member 110 and second frame member 130 in the storage position, bottom surface 120 of first frame member 110 may form an acute angle (i.e., between 0° and 90°) with bottom surface 140 of second frame member 130. The acute angle may be between 10 degrees and 45 degrees.

[0047] As shown in FIG. 7 (with the footrest 320 removed for clarity), a pair of mounting brackets 123 can pivotally connect the first frame member 110 to the second frame member 130. Each mounting bracket 123 can be fixedly connected to each side surface 122 of the first frame member 110. In addition, the pair of mounting brackets 123 can be pivotally connected to the second frame member 130 at a pivot 149. The pivot 149 can be located at the center of a circular hub 145. The pair of mounting brackets 123 can engage with the side surface 142 of the second frame member 130. It is understood that the positions of the mounting brackets 123 and the circular hub 145 can be interchanged between the first frame member 110 and the second frame member 130, such that the components are reversed and the circular hub 145 is connected to the second end 114 of the first frame member 110, while the mounting brackets 123 are connected to the first end 132 of the second frame member.

[0048] Figure 7A-Figure 9The locking assembly 200 is shown. The locking assembly 200 can include a latch bar 210, a latch 230, a latch base 250, and a tongue 260. In some arrangements, the locking assembly 200 can be configured to latch over center. The latch bar 210 is pivotally connected to the latch base 250 and the latch 230. The latch bar 210 can be pivotally connected to the latch 230 at a pivot member 280 and pivotally connected to the latch base 250 at a pivot member 284 to define a pivot point at the latch base 250. The pivot member 280 can be offset and eccentrically positioned to the pivot member 284 so that the pivot member 280 moves in an orbital motion around the pivot point of the latch bar 210 at the latch base 250. In some examples, the latch base 250 can be fixedly secured to the second frame member 130, and the tongue 260 can be fixedly connected to the first frame member 110, as shown in the figure. In other examples, latch base 250 may be fixedly secured to first frame member 110, while tab 260 may be fixedly connected to second frame member 130. In some examples, when attached to first frame member 110, the bottom end of tab 260 may be located below top surface 118 of first frame member 110. When locking assembly 200 is in the locked position, latch 230 engages with tab 260, fixedly connecting first frame member 110 and second frame member 130 to each other so that rowing machine 100 is held in the use position. After second frame member 130 is rotated relative to first frame member 110 to a position close to the use position, latch bar 210 may be rotated toward top surface 138 of second frame member 130 by receiving a downward force from a user. As latch bar 210 rotates toward second frame member 130, latch 230 may move toward tab 260. As the latch bar 210 rotates toward the top surface 138 of the second frame member 130, the latch bar 210 moves the engagement surface 232 of the latch 230 to contact and engage the contoured surface 262 of the tongue 260. The contoured surface 262 of the tongue 260 may have an upper portion 264 and a lower portion 266, wherein the upper portion 264 includes a convex surface and the lower portion 266 includes a concave surface. The engagement surface 232 of the latch 230 may have an upper portion 234 including a concave surface and a lower portion 236 including a convex surface. When the engagement surface 232 of the latch 230 engages with the contoured surface 262 of the tongue 260, the convex surface of the upper portion 264 of the tongue 260 may contact the concave surface of the upper portion 234 of the engagement surface 232. In addition, the convex surface of the lower portion 236 may contact the concave surface of the lower portion 266 of the tongue 260. The tab 260 may also include a rear surface 268 opposite to the contour surface 262, which engages and contacts the engagement surface 252 of the latch base 250, so that when the locking assembly 200 is in the locked position, the tab 260 is fastened between the engagement surface 232 of the latch 230 and the engagement surface 252 of the latch base 250.

[0049] To move the locking assembly 200 from the locked position to the unlocked position, the latch bar 210 is rotated away from the top surface 138 of the second frame member 130, which lifts the latch 230 and moves it away from the tongue 260. Once the latch 230 is out of engagement with the tongue 260, the locking assembly 200 is in the unlocked position. In some examples, a resilient member (e.g., a torsion spring) may be positioned between the latch 230 and the latch bar 210 to hold the latch 230 in a preset position when the locking assembly 200 is in the unlocked position. Once in the unlocked position, the rowing machine 100 may be moved from the use position to the storage position.

[0050] Figure 10-Figure 14 A resistance device 150 is shown connected near the first end 112 of the first frame member 110. The resistance device 150 may include a fan 152, which may generate resistance for the user, for example, through air resistance during rotation, when the fan rotates within a fan housing 154. The connection member 170 may be operatively connected to the resistance device 150 via a pulley system 175, and may also be connected to an exercise handle 180, so that movement of the exercise handle 180 drives movement of the fan 152 of the resistance device 150. The fan 152 generates resistance for the user against the movement of air within the fan housing 154. The fan housing 154 may have an air inlet 156 located on a side of the resistance device 150 opposite to the side on which the resistance device 150 is mounted to the first frame member 110, and an exhaust port 158 ​​disposed along a radial surface of the resistance device 150. The resistance device 150 may also include a mesh grille 160 disposed along the exhaust port 158 ​​and the air inlet 156. In addition, the resistance device 150 may also include a fixed baffle 165 and a movable baffle 162 located at the air inlet 156. Generally speaking, the fixed baffle 165 may have an opening that allows air to enter the air inlet 156, and the movable baffle 162 may have a complementary structure that can be moved to gradually open or close the opening of the fixed baffle, thereby increasing or decreasing the overall ventilation capacity of the air inlet 156. The user can move the movable baffle 162 by rotating the external handle 163. The movable baffle 162 is Figure 12-14 and Fig.25 This is most clearly shown in Figure 12-14 and Fig.25For clarity, the mesh grille 160 has been removed from the air inlet 156. The air inlet 156 is generally circular in shape. The fins 164 on the movable baffle 162 can be arranged in a spiral shape, and together with the fixed baffle 165 (which also has multiple fins in a spiral shape), regulate the amount of air that can enter the air inlet 156. For example, the movable baffle 162 can be positioned to reduce the amount of air entering the air inlet 156, thereby reducing the resistance created by the fan 152, and the movable baffle 162 can be positioned to increase the amount of air entering the air inlet 156, thereby increasing the resistance created by the fan 152. The movable baffle 162 may include tapered fins 164, the outer end of which has a thickness that is less than the thickness of the inner end. In addition, the fixed baffle 165 may receive an air inlet ring 166, which is arranged in a groove along the outer surface 167 of the fixed baffle 165, as shown. Fig.14 and Fig.24 The air inlet ring 166 can be used to further adjust or calibrate the size of the air inlet 156 to optimize the resistance generated by the fan 152. The air inlet ring 166 can be a removable annular component with different inner diameters. If the inner diameter of the air inlet ring 166 is smaller, the amount of air allowed to enter the air inlet 156 is reduced, and if the inner diameter of the air inlet ring 166 is larger, the amount of air allowed to enter the air inlet 156 is increased.
