AI Technical Summary
The existing treadmills require two independent drive mechanisms to adjust the running platform tilt angle and to stand up and fold, resulting in complex equipment and high costs.
A drive mechanism is used to adjust the tilt angle and stand up and fold the running platform by combining a telescopic rod and a switching component. The telescopic rod drives the synchronous movement of the support and the running platform, and the rollers reduce friction.
The equipment structure is simplified, costs are saved, and a single drive mechanism enables multi-functional operation of the running platform, improving space utilization efficiency.

TECHNICAL FIELD
[0001] The present application relates to the technical field of treadmills, in particular to a treadmill frame capable of folding and lifting the running deck. BACKGROUND
[0002] Treadmills are usually provided with a running deck, and a running belt is arranged on the running deck. During use, the running belt rolls backward, and the user can run forward on the running belt.
[0003] In order to simulate the climbing process in actual running, the running deck of some current treadmills is designed to be able to be lifted at the front part to adjust the inclination angle of the running deck. In order to save space when the treadmill is not in use, the running deck of some current treadmills is designed to be able to be folded vertically. However, on the current treadmills, two independent driving mechanisms are used to adjust the inclination angle of the running deck and to fold the running deck vertically.
[0004] If one driving mechanism can be used to adjust the inclination angle of the running deck and to fold the running deck vertically, the equipment will be more compact, and the cost will be effectively saved. SUMMARY

[0010] One end of the extension rod is pivotally connected to the base, and the pivot point is located behind the pivot point between the support and the base. The other end of the extension rod is pivotally connected to the running deck, and the pivot point is located in front of the pivot point between the support and the running deck, so that the support and the extension rod form an intersection.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0031] This invention provides a treadmill frame that enables the running platform to fold down and the incline to increase, such as... Figures 1-11 As shown, the focus here is on combining... Figure 1 As shown, it includes a running platform 1, a base 2, a support 3, a telescopic rod 4, and a switching component 5;
[0032] Running belts 6 are arranged in front and behind the running platform 1. The arrangement of running belts 6 on the running platform 1 is a conventional setting and will not be described in detail in this embodiment.
[0033] The front-to-back length of base 2 is less than the front-to-back length of running platform 1. Base 2 is located below the front half of running platform 1. Its specific shape is not limited, as long as it can sit stably on the ground. The rear part of running platform 1 also rests on the bottom surface.
[0034] This section will be further emphasized. Figure 2 , Figure 5 As shown, the bottom end of the bracket 3 is pivotally connected to the base 2 laterally on the left and right sides. Specifically, in this embodiment, it is pivotally connected to the front end of the base 2, and the top end of the bracket 3 is tilted backward and pivotally connected to the front half of the running platform 1 laterally on the left and right sides.
[0035] This section will be further emphasized. Figure 5 As shown, the telescopic rod 4 can be any existing telescopic drive mechanism, such as a cylinder or hydraulic cylinder. One end of the telescopic rod 4 is pivotally connected laterally to the base 2, and the pivot point with the base 2 is located behind the pivot point between the support 3 and the base 2. The other end of the telescopic rod 4 is pivotally connected laterally to the running platform 1, and the pivot point with the running platform 1 is located in front of the pivot point between the support 3 and the running platform 1, so that the support 3 and the telescopic rod 4 form an intersection, with a key connection point. Figures 4-6 As shown, when the telescopic rod 4 extends, it touches the front end of the running platform 1, causing the front end of the running platform 1 to rise, which in turn drives the top of the support 3 to swing forward and rise. At this time, because the position of the telescopic rod 4 touching the running platform 1 is in front of the pivot point between the running platform 1 and the support 3, the running platform 1 tilts backward, with the rear still on the ground, and only the front rising, thus forming a front-high-rear-low angle of elevation. As the telescopic rod 4 extends, the angle of elevation of the running platform 1 gradually increases. When the telescopic rod 4 shortens, the front end of the running platform 1 descends, and the angle of elevation decreases. (Focus on...) Figure 1 , Figure 2 As shown, when the elevation angle decreases to zero, the treadmill is brought into a horizontal position.
[0036] Key points combined Figures 2-3 ,as well as Figures 7-10 As shown, the switching component 5 is located at the front of the running platform 1. The specific structure of the switching component 5 is not limited. It is used to pivotally or detach the front end of the running platform 1 from the base 2. The pivoting shaft is coaxial with the pivoting shaft of the support 3 pivotally connected to the base 2, and the pivoting shaft is located in front of the pivot point between the running platform 1 and the telescopic rod 4. When the switching component 5 pivotally connects the front end of the running platform 1 to the base 2, the telescopic rod 4 extends and retracts, causing the running platform 1 to swing synchronously with the support 3. This allows the rear of the running platform 1 to rise and stand up with the forward swing of the support 3, realizing the folding or downward swing of the running platform 1 onto the bottom surface for use. After the running platform 1 is upright, the entire platform is above the base 2, saving more space. This section focuses on... Figure 11 As shown. In a more specific embodiment, the focus is on combining Figure 3 As shown, the switching component 5 includes a swing plate 7 and left-right extending pin holes 8 formed on the base 2. The top end of the swing plate 7 is pivotally connected to the bottom side of the running platform 1 and can swing left and right. The bottom end has left-right extending pins 9. The swing plate 7 swings left and right so that the pins 9 can be inserted into or out of the pin holes 8. The pin holes 8 are coaxial with the pivot shaft of the bracket 3 on the base 2. When the pins 9 are inserted into the pin holes 8, the front end of the running platform 1 can be pivotally connected to the base 2. When the pins 9 are out of the pin holes 8, the pivot connection between the running platform 1 and the base 2 is released.
[0037] In a preferred embodiment, the focus is on combining Figure 1 , Figure 6As shown, since the top end of the support 3 has forward displacement in the process of lifting up and has backward displacement in the process of lowering down, the treadmill 1 also has overall forward and backward displacement in the process of lifting and lowering, the rear bottom side of the treadmill 1 is provided with a roller 10 for forward and backward rolling, the treadmill 1 is supported by the roller 10 and falls on the bottom surface, in the process of lifting and lowering of the treadmill 1, the roller 10 rolls along with the forward and backward displacement of the treadmill 1 to reduce the frictional resistance between the treadmill 1 and the bottom surface.
[0038] The key is combined Figure 1 、 Figure 6 、 Figure 11 As shown, in the preferred embodiment, the base 2 is upwardly extended with handrails 11 on the left and right sides, the handrails 11 are upwardly extended to a height which is easy for the user standing on the treadmill 1 to grab, when the rear part of the treadmill 1 is lifted up to the highest position, the whole treadmill 1 is in the middle of the handrails 11.
[0039] The above description is only the preferred embodiment of the present application, and is not a limitation on the design of the present application, any equivalent changes made according to the key design of the present application shall fall within the protection scope of the present application.
