Detailed Implementation

[0022] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0023] like Figure 1 As shown in the figure, the present invention provides a foldable gantry frame, including a frame body, a counterweight unit, a high pull handle 7, and a Smith training unit. The frame body includes an upper beam 1, a ground beam 3, and an upright beam 2. Both the upper beam 1 and the ground beam 3 are U-shaped structures. Two folding arms 1 4 are hinged on the upper beam 1, and two folding arms 2 5 are hinged on the ground beam 3. The folding arms 2 5 are located directly below the folding arms 1 4, and the axis of the hinge point of the folding arms 2 5 coincides with the axis of the hinge point of the folding arms 1 4. The folding arms 1 4 are fixedly connected to the folding arms 2 5 located below them through the upright 6. Both folding arms 1 4 and both folding arms 2 5 can be folded inward.

[0024] To prevent the high pull handle 7 and the Smith training unit from affecting the folding of the frame, in this embodiment, the high pull handle 7 is hinged to one of the folding arms 4 and detachably mounted on the other folding arm;

[0025] The Smith training unit includes two slides 9 and a Smith training rod 8. The two slides 9 are respectively mounted on the column 6. The slides 9 can move along the length of the column 6. In addition, a limit structure can be installed on the column 6 to limit the lowest position of the slides 9. The limit structure and the Smith training rod 8 are existing structures. Some of their auxiliary structures are not shown in the figure. The Smith training rod 8 is hinged to one of the slides 9 and can be detachably mounted on the other slide 9.

[0026] Before folding, release the fixation of the high pull handle 7 and the Smith training bar 8. Both the high pull handle 7 and the Smith training bar 8 will change from horizontal to vertical. Then you can fold them. Compared with the usage state, it greatly reduces the area occupied, making it more suitable for home or small gym use.

[0027] Example 2

[0028] like Figures 1 to 4 Based on Embodiment 1, this embodiment proposes a foldable gantry frame, wherein the high handle 7 and one of the folding arms 4 are detachably connected as follows:

[0029] The high pull handle 7 and one of the folding arms 4 are provided with through holes 10, and the high pull handle 7 and the folding arm 4 can be fixed by the cooperation of bolts 11 and nuts 12.

[0030] The Smith machine's training bar 8 and slide 9 are detachably connected as follows:

[0031] One of the slides 9 has a support plate 13 with a through hole 14. The Smith training rod 8 has a threaded hole. The Smith training unit also includes a knob 15 with a threaded part 16 that mates with the threaded hole. The support plate 13 is located between the knob 15 and the Smith training rod 8.

[0032] The detachable structure described above allows for the removal of the high pull handle 7 and the Smith training bar 8. While enabling the two training functions mentioned above, it also allows for the folding of the gantry frame, thus meeting the requirements of multiple functions and minimizing space occupation when not in use.

[0033] Example 3

[0034] like Figures 1 to 6 As shown, this embodiment proposes a foldable gantry frame based on embodiment one or embodiment two. Its counterweight unit includes two symmetrical counterweight groups. The counterweight group includes a counterweight block assembly, multiple fixed pulleys 17, pulley rope one 18, pulley rope two 19 and a movable pulley group. The movable pulley group includes an upper pulley 20 and a lower pulley 21.

[0035] The counterweight assembly includes a lifting rod 22, multiple stacked counterweights 23, and a pin 24. The lifting rod 22 and the multiple counterweights 23 are all provided with insertion holes that mate with the pin 24. The pin 24 is fixedly connected to the lifting rod 22 by a connecting rope.

[0036] One end of the pulley rope 18 is a steel cable knot 25. The Smith training unit has two fixed pulleys 17. The steel cable knot 25 is larger than the gap between the two fixed pulleys 17. The other end of the pulley rope 18 extends upward, passes through multiple fixed pulleys 17 and upper pulleys 20 fixed on the upper beam 1 in sequence, and connects to the fixed anchor point on the upper beam 1.

[0037] The cable connector can be connected to features such as a pull-down handle (not shown in the diagram), which can expand training movements;

[0038] One end of the pulley rope 19 is connected to the Smith training unit, and the other end extends downward, passing through multiple fixed pulleys 17, lower pulleys 21, and multiple fixed pulleys 17 fixed on the ground beam 3 in sequence, and is connected to the lifting rod 22 of the counterweight assembly.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit and essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
