The pivot rod 40 is pivoted between the upper fixing member 20 and the lower fixing member 30, and includes an upper rod portion 41 pivoted on the upper pivot portions 24, a lower rod portion 42 pivoted on the lower pivot portion 34, a rod 43 provided between the upper rod portion 41 and the lower rod portion 42, and a pivot piece portion 44 provided between the rod 43 and the lower rod portion 42. The rod 43 is provided with a plurality of longitudinally arranged transverse holes 431, so that other fitness accessories (not shown) can be inserted therein to perform corresponding fitness actions, and the fitness accessories can be inserted into the transverse holes 431 at an appropriate height according to the height requirement, so as to improve the functionality of the fitness equipment; the pivot piece portion 44 includes a plurality of pivot holes 441, and each pivot hole 441 corresponds to each of the fixing holes 35 of the lower fixing member 30.
The frame 50 is foldably pivoted between the upper fixing member 20 and the lower fixing member 30, and includes an upper frame portion 51 pivotally disposed at the upper pivot portions 24, and a lower frame portion 52 pivotally disposed at the lower pivot portion 34, and a plurality of longitudinal rod portions 53 connected between the upper frame portion 51 and the lower frame portion 52. In this embodiment, the upper frame portion 51 is further pivoted to the upper rod portion 41 of the pivot rod 40 through an upper through hole 511, and the lower frame portion 52 is further pivoted to the lower rod portion 42 of the pivot rod 40 through a lower through hole 529. In addition, the lower frame portion 52 of the frame 50 is hollow, and includes an upper frame surface 521, a lower frame surface 522, a side frame surface 523 connecting the upper frame surface 521 and the lower frame surface 522, a limiting space 524 defined by the upper frame surface 521, the lower frame surface 522, and the side frame surface 523, a through hole 525 provided on the upper frame surface 521, and a side hole 526 provided on the side frame surface 523. The frame 50 is equipped with an auxiliary fitness unit 54, such as plural pulleys 541, steel cables 542, bar mounting rod 543, horizontal bar (not shown in the Fig.), single handle (not shown in the Fig.), etc.
The positioning unit 60 is assembled on the frame 50, and includes a positioning member 61 and a resetting member 62. The positioning member 61 is arranged on the lower frame portion 52 and movable between a positioning position (as shown in FIG. 4) and a release position (as shown in FIG. 5), includes a control portion 611 located below the lower frame portion 52, a positioning pin portion 612 for inserting into or detaching from the fixing holes 35, a plate portion 613 located in the limiting space 524 of the frame 50 and provided for mounting of the positioning pin portion 612, and a neck portion 614 connected between the plate portion 613 and the control portion 611 and inserting through the side hole 526. The resetting member 62 is disposed in the limiting space 524 of the lower frame portion 52 of the frame 50, and provides a restoring force for the positioning member 61 to return to the positioning position from the release position. In this embodiment, the resetting member 62 is a compression spring and includes a first end 621 abutting against the plate portion 613 of the positioning member 61, and a second end 622 which is opposite to the first end 621 and abuts against the lower frame surface 522 of the frame 50.
Referring to FIGS. 2 and 4, when the positioning member 61 is in the positioning position, the plate portion 613 of the positioning member 61 is abutted against the upper frame surface 521 of the lower frame portion 52, and the positioning pin portion 612 protrudes from the through hole 525 of the lower frame portion 52 and is inserted into the fixing hole 35 of the lower fixing member 30, so that the frame 50 is fixed to the upper fixing member 20 and the lower fixing member 30, that is, the frame 50 is unable to pivot with respect to the upper fixing member 20 and the lower fixing member 30, a fitness action can be performed. In addition, when the positioning member 61 is in the positioning position, the positioning pin portion 612 is inserted into the pivot hole 441 of the pivot rod 40 at the same time, so that the pivot rod 40 is fixed, and fitness accessories (not shown in the Fig.) can also be installed to carry out the corresponding fitness activity.
Referring to FIG. 5, when the positioning member 61 is in the release position, the positioning pin portion 612 and the fixing hole 35 of the lower fixing member 30 are separated from each other, so that the frame 50 is able to pivot relative to the upper fixing member 20 and the lower fixing member 30, and at the same time, the plate portion 613 of the positioning member 61 presses against the resetting member 62, so that the resetting member 62 accumulates an elastic restoring force.
Accordingly, referring to FIGS. 2, 4, and 5, when the invention is to be folded, the user steps down the control portion 611 of the positioning member 61, or makes the control portion 611 of the positioning member 61 move downward by other means, so that the positioning pin portion 612 moves downward simultaneously, and then disengages from the fixing hole 35 of the lower fixing member 30, so as to release the frame 50 from a fixed state with respect to the upper fixing member 20 and the lower fixing member 30. At this time, referring to FIGS. 6 to 8, push the frame 50 toward the setting surface 11, and when the frame 50 abuts against the setting surface 11, release the control portion 611 of the positioning member 61, so that the positioning member 61 is pushed by the resetting member 62 to move upward, and then the positioning pin portion 612 of the positioning member 61 is caused to protrude from the through hole 525 of the lower frame portion 52 and is inserted into the fixing hole 35 of the lower fixing member 30 again, so that the frame 50 is fixed relative to the upper fixing member 20 and the lower fixing member 30, so as to complete the folding and positioning of the frame 50 after folding, and achieve the purpose of improving the convenience of space use.
It is worth noting that, as shown in FIG. 9, since the frame 50 is equipped with an auxiliary fitness unit (such as the lever 54), before folding the invention, the lever 54 is first removed, and then the positioning member 61 is controlled, and the frame 50 is folded and positioned after folding.
In addition, referring to FIGS. 5 and 10, when the positioning member 61 is in the release position, the positioning pin portion 612 is separated from the fixing hole 35 of the lower fixing member 30, the positioning pin portion 612 is further separated from the pivot hole 441 of the pivot piece portion 44 of the pivot rod 40. At this time, the angle of the pivot rod 40 can be adjusted to meet actual requirements.
Please refer to FIGS. 11 and 12, the second embodiment of the present invention provides a foldable fitness equipment, which differs from the first embodiment in that:
The upper frame portion 51 of the frame 50 is fixed on the upper rod portion 41 of the pivot rod 40, and the lower frame portion 52 of the frame 50 is fixed on the lower rod portion 42 of the pivot rod 40 so that the frame 50 and the pivot rod 40 are fixed into one unitary and move simultaneously, and the fixing can be achieved by tight fitting or welding, but it is not limited to this. Since the frame 50 and the pivot rod 40 are fixed to each other as one unitary, and the positioning unit 60 is assembled on the frame 50, the folding and positioning after folding can be achieved simply by inserting the positioning pin portion 612 of the positioning member 61 into or separating it from the fixing hole 35 of the lower fixing member 30. Therefore, the structural design of the pivot rod 40 of the second embodiment does not need a pivot piece portion and the pivot hole as compared with the first embodiment, which effectively reduces the complexity of the structure and the manufacturing cost.
Please refer to FIG. 13, the third embodiment of the present invention provides a foldable fitness equipment, which is different from the first embodiment in that:
The foldable fitness equipment further includes a support rod 70, the support rod 70 includes a connecting portion 71 and a support portion 72, the connecting portion 71 is fixed on an end surface of the lower frame portion 52 of the frame 50, the support portion 72 and the connecting portion 71 form an angle, the support portion 72 abuts against a plane 12 (for example, the ground), and the plane 12 is perpendicular to the setting surface 11. With the support of the support rod 70, the structural strength of the invention can be increased when in use. In this embodiment, the support portion 72 of the support rod 70 is a wheel but not limited to this, so as to reduce the friction with the plane 12 when the frame 50 is folded or when the angle is adjusted, and the plane 12 can be prevented from being scratched and damaged.
While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
