Description

Field of the invention

[0001] The invention relates to the technical field of sports and fitness equipment, in particular a treadmill frame structure. State of the art

[0002] The treadmill is a commonly used sports and fitness equipment. With the continuous improvement of people's living standards, more and more treadmills are being used in ordinary people's homes, and therefore the requirements for treadmills are also becoming higher and higher. State-of-the-art treadmills usually include components such as the frame, running board, and belt. The frame is a frame-shaped structure. The two sides of the running board are fixed to the side bars on two opposite sides of the frame. The belt is attached to the frame via the front and rear rollers and runs around the running board. The running board is a support body that assists the runner during running, and the side bars are components that serve to support the running board. The runner stands on the running board via the belt. When the belt rotates, the runner must stay on the running board by running.The prior art running board is typically a rigid, flat plate that is uncomfortable for the runner. To improve running comfort, a prior art treadmill uses springs at localized positions under the running board or an elastic rubber pad to provide cushioning when the runner steps on it. However, this prior art treadmill has the following disadvantages: First, because buffer components such as springs are locally attached and cannot provide buffering for the entire running board, the contact is still hard when the runner steps on it, which can easily cause impact and damage to the runner's knee and ankle joints, thus causing discomfort to the runner.

[0003] Secondly, the treadmill tends to produce noise that causes discomfort to those around it. Object of the invention

[0004] The object of the invention is to overcome the deficiencies of the prior art and provide a treadmill frame structure. Structural improvements allow the entire running board to be cushioned, thereby preventing damage to the runner's knee and ankle joints caused by hard contact when the runner steps on the running board and reducing the noise of the treadmill.

[0005] The technical solution of the invention is as follows: A treadmill frame structure comprising a frame, a running board, and a belt, wherein the frame has a frame-shaped element, wherein a motor and a transmission mechanism for driving the belt are provided in the frame, wherein the belt is mounted to the frame via the transmission mechanism and surrounds the running board from top to bottom, wherein the frame-shaped element of the frame is provided with side bars on two opposite sides of the frame, characterized in that the running board has soft elastic strips mounted on the two side bars of the frame, a plurality of rigid support strips mounted between the two soft elastic strips, and connecting strips connected to the two ends of the plurality of rigid support strips, wherein the two connecting strips are connected to the upper surfaces of the rigid support strips,and wherein the connecting strips are attached to the corresponding ends of each rigid support strip.,

[0006] The connecting strips are attached to the corresponding ends of the rigid support strips using hexagon socket screws.

[0007] The soft elastic strips each form a recess on the top, with the two ends of the rigid support strips protruding into the recesses of the two soft, elastic strips.

[0008] The side bars of the frame are each provided with a stopper at the two ends of the recesses of the soft elastic strips.

[0009] The running board also includes a thin abrasion-resistant plate, with the thin abrasion-resistant plate covering the plurality of rigid support strips.

[0010] One end of the thin friction-resistant plate is attached to the corresponding rigid support strip and the other end of the thin friction-resistant plate is clamped on the corresponding rigid support strip.

[0011] One end of the thin friction-resistant plate is attached to the corresponding rigid support strip by countersunk screws.

[0012] The corresponding ends of the connecting strips are each provided with a clamping element, whereby the other end of the thin friction-resistant plate is clamped onto the corresponding rigid support strip by the clamping element.

[0013] The clamping element is a Z-shaped metal sheet, one end of the Z-shaped metal sheet being fixed to the corresponding end of the connecting strip by a screw, and the other end of the Z-shaped metal sheet pressing the other end of the thin friction-resistant plate towards the corresponding rigid support strip.

[0014] The two connecting strips are thin spring steel plates.

[0015] Compared with the prior art, the advantages of the invention are as follows: The treadmill frame structure of the invention uses a running board comprising soft elastic strips arranged on the side bars of the frame, a plurality of rigid support strips arranged between the two soft elastic strips, and connecting strips connected to the two ends of the plurality of rigid support strips. The two connecting strips are connected to the upper surfaces of the rigid support strips. The connecting strips are fixed to the corresponding ends of the rigid support strips. The structure of the invention realizes elastic buffering of the entire running board through the soft elastic strips on the two side bars.In particular, the rigid support strips are connected to each other by connecting strips, which eliminates the uneven transition of the rigid support strips when the runner steps onto the running board, improving the comfort of the runner's feet. Furthermore, the soft elastic strips can provide cushioning on the side bars, reducing the noise generated by the movement of the treadmill.
