[0002] The fitness handrail structure is an innovative component designed specifically for treadmills, a type of fitness equipment, to solve the problems of traditional treadmills where fixed handrails take up too much space and are inconvenient to move and store. This structure allows users to fold or stow the handrails when the treadmill is not in use, thereby significantly reducing the overall size of the equipment and making it easier to store in small spaces at home.

[0003] Chinese patent application number 202223604279.3 discloses a folding mechanism and a treadmill. The crossbeam and column of the folding mechanism's support frame are movably connected via a first connecting component. The crossbeam can rotate relative to the column within a predetermined plane at a preset angle. The handrail and crossbeam are movably connected via a second connecting component, allowing the handrail to rotate relative to the crossbeam around a predetermined axis at a predetermined angle. Through the relative rotation between the crossbeam and column, and between the handrail and crossbeam, the handrail can be folded in two directions. However, this handrail lacks a limiting structure during unfolding and folding, affecting its stability after unfolding and folding.

[0004] The existing fitness handrail structure makes it difficult to limit the support structure after unfolding and folding, which can easily lead to instability when unfolded and unevenness when folded, affecting the user experience. Utility Model Content

[0027] Furthermore, the running frame 1 has an installation shaft 11 installed inside, and the housing 3 and the bracket 4 are movably fitted onto the surface of the installation shaft 11.

[0028] Furthermore, a fastening knob 2 is installed on one side of the housing 3, and a screw 10 is installed inside the fastening knob 2. The screw 10 passes through the housing 3 and the bracket 4 and is threadedly connected to the inside of the mounting shaft 11. The mounting shaft 11 has a threaded hole inside that is used to cooperate with the screw 10.

[0029] Furthermore, the running frame 1 has a card seat 16 on both the front and rear sides. The card seat 16 is sleeved on the surface of the mounting shaft 11. The bracket 4 has a card cover 15 fixedly installed inside. The card cover 15 engages with the card seat 16. The bracket 4 is limited by the card cover 15 and the card seat 16. One end of the card seat 16 has a card groove, and the card cover 15 has a card tooth that works with the card groove.

[0030] Furthermore, the bracket 4 is made of elastic material, and the bottom of the bracket 4 is inclined outward. When the fastening knob 2 presses against the housing 3, the bracket 4 drives the cover 15 to engage with the seat 16. When the fastening knob 2 releases the housing 3, the bottom of the bracket 4 moves outward, causing the cover 15 to disengage from the seat 16.

[0031] Furthermore, a first limiting piece 13 is fixedly connected to the surface of the card holder 16, and a first limiting pin 14 is fixedly connected to the inner side of the bracket 4. The first limiting pin 14 is located on the surface of the first limiting piece 13 and is movably connected to it. The first limiting pin 14 and the first limiting piece 13 limit the housing 3 and the bracket 4 in the vertical and horizontal states.

[0032] Furthermore, a positioning pin 12 is fixedly installed inside the housing 3, and the bracket 4 is installed on the positioning pin 12. The housing 3 is fixedly connected to the bracket 4 by bolts.

[0033] Furthermore, a second limiting pin 5 is installed on the handrail 6, and a second limiting piece 17 is fixedly connected to the handrail base 9. The second limiting pin 5 and the second limiting piece 17 are movably connected to each other to limit the handrail 6 in the vertical and horizontal states.

[0034] Furthermore, a display screen 7 is fixedly installed on the armrest seat 9.

[0035] Furthermore, a touch control panel 8 is fixedly installed on the armrest seat 9.

[0036] Furthermore, when it is necessary to store the handrail structure, first store the handrail 6, rotate the handrail 6 upward, the handrail 6 drives the second limiting pin 5 to rotate, rotate the second limiting pin 5 to the bottom of the second limiting piece 17, the second limiting piece 17 limits the handrail 6 and the second limiting pin 5, so that the handrail 6 fits against the front and rear sides of the handrail seat 9.

[0037] By rotating the screw 10 outward by the fastening knob 2, the limiting of the housing 3 and the bracket 4 is released. Due to the outward tension at the bottom of the bracket 4, the bracket 4 drives the cover 15 to disengage from the seat 16. Then, the housing 3 and the bracket 4 are rotated downward, and the housing 3, the bracket 4 and the handrail 6 are stored in the front and rear sides of the running frame 1. After storage, the first limiting pin 14 moves to the bottom of the first limiting piece 13 to prevent the housing 3 and the bracket 4 from moving downward too much and colliding with the ground. Finally, the fastening knob 2 and the screw 10 are reset. The fastening knob 2 and the screw 10 continue to fix the housing 3 and the bracket 4 in the front and rear sides of the running frame 1. The fastening knob 2 applies pressure to the bottom of the bracket 4, so that the bottom of the bracket 4 drives the cover 15 to engage with the seat 16, and continues to fix the bracket 4.

[0038] Furthermore, when it is necessary to unfold the handrail structure, unscrew the fastening knob 2 and screw 10 outwards, then rotate the bracket 4 upwards to erect the bracket 4 on top of the running frame 1. After unfolding, the first limiting pin 14 moves to the top of the first limiting piece 13 to prevent the bracket 4 from unfolding excessively, so that the housing 3 can stand vertically at ninety degrees on top of the running frame 1. Then rotate the fastening knob 2 and screw 10 inwards to fix the housing 3 and bracket 4, and reset the handrail 6 to unfold it to assist fitness enthusiasts in running exercises.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
