1 is a perspective view showing a rowing machine 1 and a folding device thereof according to an embodiment of the present invention. Preferably, the rowing machine 1 comprises a first main frame 10, a second main frame 11, a handle 12, and a resistance device (not shown).

In addition, referring to FIG. 1, a slide 111 is disposed on the slide rail 115 above the second main frame 11, and the slide 111 can reciprocate along the slide rail 115. The carriage 111 has a seat (not shown). The two sides of the second main frame 11 each have a pivot 114 and are respectively pivotally connected to a pedal 16. The resistance device can include a magnetron wheel, such as a flywheel, and the magnetron wheel is coupled to the handle 12 via a strap (not shown) that the user can pull to drive the flywheel to rotate. During operation, the user sits on the seat above the sliding seat 111, and the two feet are respectively placed on the two pedals 16. When the two hands hold the handle 12 to pull the connecting belt out, the sliding seat 111 will follow the upper part of the second main frame 11. The slide rail 115 moves backward. In addition, a homing device (not shown) pulls the handle 12 back to the original position through a connecting strap (not shown), at which time the strap guides the user to move forward, and the strap 111 moves forward along the slide rail 115. mobile.

Referring to FIG. 1, preferably, the front end of the first main frame 10 has a front support leg 101, and the rear end of the second main frame 11 has a rear support leg 113. The front support leg 101 and the rear support leg 113 can support the first support leg 113. The main frame 10 and the second main frame 11 are pivotally connected to the front end of the second main frame 11 , and the rear end of the second main frame 11 and the rear support leg 113 are pivotally connected to the pivot 1130 . The front end of the first main frame 10 may have a bracket 102, and the resistance device may be disposed on the bracket 102. A guiding member 13 is fixed to the rear end of the first main frame 10, and the second main frame 11 and the first main frame 10 are pivotally connected to the pivot 130 of the guiding member 13. The guiding member 13 can have a limiting rod 134 for limiting the rotation angle of the pedal 16. Since the pedal 16 is pivotally connected to the pivot 114, the rotation angle of the pedal 16 is limited by the limiting rod 134. Stable pedaling. The guide member 13 can be formed by a method such as punching, casting, or pressing. If the user wants to fold the rowing machine 1, the rear support leg 113 can be folded to be parallel with the second main frame 11, and the second main frame 11 is pulled up by the handle 112 to make the second main frame 11 and the first main frame 11. 10 is approximately vertical as shown in FIG. The detailed folding structure and process will be described as follows.

2 to 7 are partial enlarged views showing the folding structure and the folding process of the treadmill of the preferred embodiment of the present invention. For the sake of clarity, some of the elements are indicated by dashed lines.

As shown in FIG. 1 and FIG. 2, the guiding member 13 is fixed to the outer sides of the rear end of the first main frame 10. The guiding member 13 has a sliding slot 132. The first main frame 10 and the second main frame 11 are pivotally connected to each other. The shaft 130 and the front end of the second main frame 11 have a fixing portion 110. When the rowing machine 1 is deployed for use, the first main frame 10 and the second main frame 11 are parallel, and the fixing portion 110 at the front end of the second main frame 11 is placed in the first main frame 10. Preferably, the fixing portion 110 has a sector-shaped structure. In other embodiments, the securing portion 110 can be polygonal or other similar to a sector. Preferably, the fixing portion 110 has an unfolding positioning groove 1102, a folding positioning groove 1104, and a curved surface 1106. The first main frame 10 has a shaft 103 disposed laterally below the first main frame 10, and a torsion spring 15 is sleeved on the support shaft 103. The torsion spring 15 has two ends, one end of which is connected to the bottom of the first main frame 10, and the other end is connected to the lever 14. The front end of the trigger lever 14 has a wrench portion 142 having a cross bar 140 at the end. The crossbar 140 of the lever 14 passes through the chute 132, and the chute 132 is used to restrict the movement path of the guide rail 140. When the rowing machine 1 is deployed, the first main frame 10 and the second main frame 11 are parallel, and the cross bar 140 is placed on the unfolding positioning groove 1102 of the fixing portion 110 of the second main frame 11 and the sliding of the guiding member 13 The upper end 1322 of the slot 132 is configured to secure the second main frame 11 such that it cannot rotate about the pivot 130.

As shown in FIG. 3 and FIG. 4, when the user wants to fold the rowing machine 1, the wrench portion 142 of the trigger lever 14 can be pulled upward, so that the crossbar 140 at the rear end of the trigger lever 14 is lowered downward to be separated from the deployment of the fixing portion 110. The slot 1102 is positioned and moved from the upper end 1322 of the slot 132 of the guide 13 to the lower end 1324 of the slot 132.

Referring to FIG. 5, since the crossbar 140 of the lever 14 is disengaged from the unfolding positioning groove 1102 of the fixing portion 110 of the second main frame 11, the second main frame 11 is rotated about the pivot 130. At this time, the user can pull the handle 112 to make the second main frame 11 and the first main frame 10 assume a vertical or nearly vertical state. When the second main frame 11 is folded, the torsion spring 15 provides a force to cause the lever 14 Rotating counterclockwise about the fulcrum 103 causes the crossbar 140 at the end of the ram 14 to move against the curved surface 1106 of the fixed portion 110.

Referring to FIGS. 6 and 7, since the torsion spring 15 always provides the force that the wrench 14 rotates counterclockwise about the support shaft 103, when the second main frame 11 and the first main frame 10 assume an approximately vertical state, the fixing portion 110 at this time. The folding positioning groove 1104 is located above the cross bar 140, and the torsion spring 15 provides a force to engage the cross bar 140 of the trigger bar 14 into the folding positioning groove 1104 of the fixing portion 110, thereby fixing the second main frame 11 . The rowing machine 1 after folding is shown in FIG.

According to the folding device of the rowing machine of the present embodiment, the utility model has the advantages of convenient operation, fast and accurate positioning.
