Thus, for example, reference to "an element" means one or more of the element, and includes equivalents thereof known to those skilled in the art. All conjunctions used in a similar sense are to be understood in the broadest sense and the particular shapes and structural features or technical terms described in the specification are likewise to be understood as including equivalent structural or technical terms to the functions which the particular structures or technical terms are capable of achieving.

In order to explain the technical features of the present invention in detail, the following embodiments will be described with reference to the accompanying drawings, wherein for convenience of explaining the following embodiments, the following embodiments will be described with reference to the direction in which the sub-frame 20 of the rowing machine is located in front of the rowing machine.

As shown in fig. 1 to 9, the embodiment of the present invention provides a rowing machine 1, which includes a main frame 10, a sub-frame 20, a force applying grip 30 and a resistance device 40.

The main support 10 includes a slide rail 11 and a base 12 integrally connected, the slide rail 11 is located above the base 12, the slide rail 11 has a flat top surface, and two sides are provided with protruding edge portions 111. An accommodating space 13 is provided between the slide rail 11 and the base 12, the accommodating space 13 is used for installing the resistance device 40, as shown in fig. 1, the rear half of the slide rail 11 is directly above the resistance device 40. A set of pedals 14 are further provided on both sides of the front half of the main stand 10.

Please refer to fig. 1 and fig. 9. A seat cushion 50 is slidably disposed on the slide rail 11, and the seat cushion 50 structurally includes a cushion body 51, a set of mounting brackets 52, two sets of upper rollers 53 and a set of lower rollers 54. The set of mounting brackets 52 are fixed to the bottom of the cushion body 51 at intervals, two upper connecting shafts 55 and two lower connecting shafts 56 are disposed between the set of mounting brackets 52, the two sets of upper rollers 53 are respectively rotatably disposed on the two upper connecting shafts 55, the set of lower rollers 54 are respectively rotatably disposed on the two lower connecting shafts 56, and as shown in fig. 1, the edge 111 of the slide rail 11 is located between the upper rollers 53 and the lower rollers 54.

Please refer to fig. 2. The slide rail 11 is bent upwards from front to back gradually, and the top surface of the slide rail 11 is a circular arc surface with a curvature radius of R. The radius of curvature R may be adjusted as appropriate. In other possible cases, the top surface of the slide rail 11 may also be, for example, an ellipsoid or other form of curved surface.

Since the slide rail 11 of the present embodiment is bent upward gradually from front to back, when the user steps on the set of pedals 14 and holds the force application grip 30 with his hands to perform the rowing exercise, the buttocks of the user together with the seat cushion 50 will slide backward along the slide rail 11, and the height of the user in the sitting posture will gradually rise as the seat cushion 50 slides backward. Compared with the conventional rowing machine 1 in which the slide rails 11 extend straight from front to back, the seat cushion 50 of the present embodiment can rise higher along the bent slide rails 11, so that the component force of the self weight of the load required by the legs of the user is greater, thereby generating a higher weight load to the legs of the user, and enhancing the exercise and fitness effects of the user.

The present invention also provides a folding mechanism of the rowing machine 1, please refer to fig. 10 to 15.

Please first refer to fig. 13. The secondary support 20 is disposed in front of the main support 10, the secondary support 20 includes a secondary support body 21 and a rotating shaft 22, one end of the rotating shaft 22 is fixedly connected to the secondary support body 21, and the other end of the rotating shaft 22 opposite to the secondary support body is pivotally connected to the front end of the main support 10 (as shown in fig. 15), so that the secondary support 20 can pivot between an expanded position (as shown in fig. 13) and a collapsed position (as shown in fig. 14) through the rotating shaft 22. The shaft 22 is made of a solid material (e.g., metal), the front end of the main support 10 is further provided with a stop member 15, and the stop member 15 is also made of a solid material, so that when the secondary support 20 pivots to the folded position, the middle section of the shaft 22 abuts against the stop member 15 of the main support 10 and is stopped by the stop member 15, so that the secondary support 20 cannot further pivot towards the main support 10.

Please refer to fig. 10 to fig. 12. The bottom of the front end of the main bracket 10 is provided with a screw seat 16, the screw seat 16 is provided with a screw hole (hidden at the end of the locking bolt), a fixing bolt 17 is locked on the screw hole, and the fixing bolt 17 is provided with a screw rod part (see fig. 12) and a tightening part 19 which are connected. The bottom of the secondary bracket 20 is provided with a fastener 23, the fastener 23 has two fastening portions 232 and an opening 231 in the center, the two fastening portions 232 are respectively located at two sides of the opening 231 and extend toward the primary bracket 10, and the opening 231 is used for the fixing bolt 17 to pass through. When the secondary bracket 20 is located at the unfolding position, the fastener 23 is abutted against the screw seat 16, the screw part of the fixing bolt 17 passes through the opening 231 of the fastener 23 and is screwed with the screw hole of the screw seat 16, and the tightening part 19 is abutted against the fastener 23 and tightens the fastener 23, so that the secondary bracket 20 and the main bracket 10 can be combined into a whole through the fastener 23, the screw seat 16 and the fixing bolt 17.

When the user needs to fold the rowing machine 1 and needs to pivot the sub-bracket 20 from the unfolded position to the folded position, the user can first unscrew the fixing bolt 17, so that the fastening portion 19 of the fixing bolt 17 does not fasten the fastener 23, and then the user can hold the sub-bracket 20 and pivot the sub-bracket 20 to the folded position, at this time, the middle section of the rotating shaft 22 is stopped by the stopper 15. Therefore, the whole volume and the volume during transportation of the rowing machine 1 can be reduced, and the rowing machine 1 can be folded when a user uses the rowing machine 1 at home, so that the space is saved.

The present invention also provides a handle fixing mechanism of the rowing machine 1, please refer to fig. 16 and 17. The force application grip 30 can be held by a user for exercise, thereby achieving the effects of exercise and fitness. As shown in fig. 16, the bottom of the force applying handle 30 is provided with a fixing groove 31, and a first magnetic member 32 is disposed in the fixing groove 31, in this embodiment, the first magnetic member 32 is an iron sheet.

The convex portion 24 of the sub-bracket 20 is provided with a second magnetic element 241, the second magnetic element 241 is a magnet in this embodiment, and the second magnetic element 241 can magnetically attract the first magnetic element 32, so that the force applying grip 30 is more firmly combined with the convex portion 24 of the sub-bracket 20.

Through the design of the handle fixing mechanism of the above embodiment, when the user wishes to fold the rowing machine 1, since the force application handle 30 is integrated with the sub-frame 20 through the fixing groove 31 thereof, and the first magnetic attraction piece 32 of the fixing groove 31 is attracted by the second magnetic attraction piece 241 of the sub-frame 20, so that the force application handle 30 can be stably combined with the fixing groove 31, the force application handle 30 is not easily separated from the sub-frame 20 in the process of folding the sub-frame 20, so that the user can relatively conveniently and easily fold the force application handle 30, and the force application handle 30 can be prevented from being damaged due to accidental falling in the folding process.

In order to effectively reduce the overall volume of the rowing machine 1, the present embodiment further provides the resistance device 40 below the slide rail 11. Please refer to fig. 1, 18 to 20.

Referring to fig. 20, the entire resistance device 40 is of a modular design, and the entire resistance device 40 is located directly below the rear half of the slide rail 11.
