[0002] Among existing fitness equipment, the equipment used for multi-position training is often called a multi-functional trainer. This type of equipment has a symmetrical adjustable load design, which can help trainees to exercise in standing, half-squatting, sitting and lying positions. For specific structure, please refer to the multi-functional training equipment with patent number 200810135111.8.

[0003] The current technical problem is that these training machines are commercial equipment, typically used in gyms, which occupy a large amount of space and are generally not moved after installation, so space occupancy is not a concern for users. However, as people's living standards improve, more and more families are paying more attention to fitness. Currently, dumbbells, barbells, or small stretching equipment suitable for home use are no longer sufficient to meet actual needs. However, considering the limited space in homes, large fitness equipment with multiple stretching functions cannot be installed and used in homes, let alone enable multi-position training at home.

[0004] In view of the shortcomings of the prior art described above, based on market feedback, it is very necessary for technical developers in this field to design a foldable functional trainer that can be folded and adjusted, and can perform multi-position stretching training in a semi-folded or open state, so as to solve the practical technical problems encountered in the prior art.

In this embodiment, the left corner bracket 1 and the right corner bracket 11 are separate units, with a rear guard plate 3 between them. The rear guard plate 3 is segmented and bent, and its top surface has a locking surface 31 that locks and fixes it to the top surfaces of the left corner bracket 1 and the right corner bracket 11 respectively. To improve the overall strength of the left corner bracket 1 and the right corner bracket 11, a top reinforcing plate 10 and a bottom reinforcing plate 33 are fixed at the top and bottom of the units respectively.

[0029] This folding functional training device has a folding frame I2 hinged to the left corner frame 1 and a positioning lock 6 between them; a folding frame II4 hinged to the right corner frame 11 and a positioning lock 6 between them; both the bottom of the folding frame I2 and the folding frame II4 are equipped with casters 25, which provide support for the movement of the entire folding frame I2 and folding frame II4 when they are half-folded or extended.

[0030] This technical solution also discloses a positioning lock 6, such as Figure 3As shown, it includes a positioning plate 61 and a positioning pin 64; the positioning plate 61 is provided with two corner positioning holes 62, the positioning pin 61 is surrounded by a fixing cylinder 63, the positioning pin 64 is a stepped shaft, a locking cap 66 fixes the stepped shaft in the fixing cylinder 63, a locking spring 67 is also provided between the stepped shaft and the fixing cylinder 63, and a handle 65 is provided around the positioning pin 61 as a force application part; by pulling the handle 65, the positioning pin 61 can be moved inside and outside the corner positioning holes 62 to achieve the locking state.

[0031] In practical applications, the fixing cylinder 63 is directly or indirectly fixed to the folding frame I2 and the folding frame II4, and the positioning plate 61 is fixed to the left inner corner frame 1 and the right inner corner frame 11.

[0032] This invention provides vertical guide rods 19 inside both the left and right corner brackets 11. Taking the left corner bracket 1 as an example, two vertical guide rods 19 are arranged parallel to each other. Several counterweight plates 14 are slidably arranged on the vertical guide rods 19. Each counterweight plate 14 is provided with a counterweight adjustment hole 15 for adjusting the counterweight. This adjustment method is the same as the counterweight adjustment method in the prior art, and will not be described in detail here. A movable pulley 16 is connected to the upper part of the counterweight plate 14. A counterweight guide is provided in conjunction with the movable pulley 16. The frame includes wheel I 12 and counterweight guide wheel II 13; the top of the left corner frame 1 and the right corner frame 11 are also respectively provided with a top guide wheel 18 and a bottom guide wheel 32; the folding frame I 2 and the folding frame II 4 are respectively provided with a traction positioning rod 22, and the traction positioning rod 22 is provided with several positioning holes 23, through which the traction device 5 is fixed. The side of the traction device 5 is provided with a locking sleeve 51 that is inserted into the traction positioning rod 22, and the locking and positioning during vertical movement is achieved by a locking device 52. In conjunction with the traction device 5, the top pulley 20 of the traction device and the bottom pulley 25 of the folding frame I 2 and the folding frame II 4 are respectively provided with the top of the traction device 5.

[0033] A steel cable 8 passes through the puller 5, the top pulley 20 of the puller, the counterweight guide wheel I 12, the movable pulley 16, the counterweight guide wheel II 13, the top guide wheel 18, and the bottom guide wheel 32, then passes through the bottom pulley 24 of the puller before connecting to the puller 5 to form a traction circuit. Furthermore, since this foldable functional trainer needs to have semi-folding and extended functions during use, in order to prevent the steel cable 8 from getting tangled, this device is specially equipped with an upper folding guide wheel 26 and a lower folding guide wheel 17 at the hinge between the left inner corner frame 1 and the folding frame I 1, and at the hinge between the right inner corner frame 11 and the folding frame II 4. The upper and lower folding guide wheels guide the steel cable 8 of this foldable functional trainer in the semi-folded and extended states, which can ensure that the traction function operates normally in any state.

[0034] In this folding functional training device, at least one of the folding frame I2 and folding frame II4 is provided with a front bending extension frame 41. In this embodiment, the front bending extension frame 41 is provided on the folding frame II4, and the front bending extension frame 41 is provided with a front mirror 42.

[0037] Furthermore, such as Figure 5 As shown, the included angle B between the left corner bracket 1 and the right corner bracket 11 is less than 85 degrees. In this embodiment, 80 degrees is selected. Since the corner of the wall is usually designed to be 90 degrees, this design allows the left corner bracket 1 and the right corner bracket 11 to have a certain gap between them and the wall when they are placed against the wall. There are operating gaps 43 at the hinge between the left corner bracket 1 and the folding frame I2, and at the hinge between the right corner bracket 11 and the folding frame II4. In the folded state, the operator can put their hand under the positioning lock 6 in this area to apply force to pull it between locked and unlocked, which facilitates the extension operation.

[0038] After the above structural adjustments, the operator can adjust the height of the puller 5 on the pull positioning rod 22 to perform single-arm, double-arm, leg, shoulder, and back training while standing; and perform single-arm and double-arm assisted training in various positions while sitting or lying down with the help of an external training bench.

[0039] This device can be extended, semi-folded, and folded. In the folded state, the device can be stored in a small area and can be placed in a corner, taking up little space. In the extended and semi-folded states, it can enable people to perform stretching training in at least 12 positions, including standing, sitting, lying down, etc. It overcomes the drawback of existing large commercial equipment that cannot be used in the home, and is an ideal foldable functional training device.
