Description

Technical Field

[0001] The invention relates to the technical field of sports fitness equipment, in particular to a treadmill. Background Art

[0002] The treadmill is a commonly used sports fitness equipment. With the continuous improvement of people's living standards, more and more treadmills have entered ordinary people's homes, so the requirements for treadmills are getting higher and higher. The treadmill of the prior art usually includes components such as a treadmill, a running board and a running belt. The treadmill is a frame-shaped structure. The two sides of the running board are fixed on the side rods corresponding to the two opposite sides of the frame of the treadmill. The running belt is installed on the treadmill through front and rear rollers and surrounds the upper and lower parts of the running board. The running board is used as a support body to support the runner to run, and the side rods are used to support the running board. The runner stands on the running board through the belt. When the belt moves, the runner must stay on the running board through running. The running board of the prior art is usually a rigid flat plate, which brings discomfort to the runner's movement. In order to improve the comfort of running, a treadmill of the prior art is supported by a spring or an elastic rubber pad at a local position below the running board to achieve buffering when the runner steps. This treadmill of the prior art mainly has the following disadvantages:

[0003] First, since buffer components such as springs are located in local positions and cannot provide buffering for the entire running board, runners will still experience hard contact when stepping on the running board, which can easily cause impact and damage to the runner's knee and ankle joints, thereby causing some discomfort to the runner.

[0004] Second, treadmills tend to generate noise, which brings discomfort to the surrounding environment. Summary of the invention

[0005] The object of the present invention is to overcome the deficiencies of the prior art and to provide a treadmill which, through structural improvement, can, on the one hand, achieve cushioning of the entire running board, thereby avoiding damage to the runner's knee and ankle joints caused by hard contact when the runner steps on the running board; on the other hand, it can also reduce the noise of the treadmill; and has the characteristics of low manufacturing cost and easy assembly.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a treadmill, comprising a treadmill, a running board and a running belt; the treadmill is a frame-shaped structure, and a motor and a transmission mechanism thereof are installed in the treadmill for driving the running belt to move; the running belt is adapted to the treadmill through the transmission mechanism, and surrounds the running board from the front and back of the running board above and below the running board; side rods are provided on the two opposite sides of the treadmill corresponding to the frame-shaped sides; strip bodies made of foamed thermoplastic polyurethane elastic material are respectively mounted on the two side rods, and the strip bodies are entirely covered on the upper surface and at least one side surface of the side rods; first grooves are respectively provided on the opposite sides of the two strip bodies, and the two side edges of the running board are respectively inserted into the first grooves of the two strip bodies, and the length of the strip bodies is greater than the length of the running board, so that the elastic effect of the strip bodies can be used to buffer the entire running board.

[0007] The running board is an integral plate, and both side edges of the running board are integrally inserted into the first grooves of the two strip-shaped bodies.

[0008] The running board is an integral plate member, and both side edges of the running board are respectively provided with a plurality of convex edges, and the dimensions of each convex edge along the length direction of the running board are the same; the first grooves of the strip-shaped body are set to correspond to and match the plurality of convex edges of the running board; the plurality of convex edges on both side edges of the running board are respectively inserted into the corresponding first grooves of the two strip-shaped bodies.

[0009] The running board is composed of multiple small strips, and the first grooves of the strip body are set to correspond to and match the multiple small strips of the running board; the two ends of the multiple small strips are respectively inserted into the corresponding first grooves of the two strip bodies.

[0010] Furthermore, a pad is provided on the entirety of the plurality of small strips.

[0011] The plurality of first grooves of the strip-shaped body are arranged in a straight line along the length direction of the strip-shaped body, and the pad is in a planar shape.

[0012] The plurality of first grooves of the strip-shaped body are arranged in an arc line along the length direction of the strip-shaped body, and the pad is in an arc surface shape.

[0013] The upper surface of the strip-shaped body is a plane.

[0014] The upper surface of the strip-shaped body is provided with an anti-slip surface.

[0015] The bottom surface of the strip body is provided with a second groove which is concave upward, and the second groove runs through the front and rear ends of the strip body along the length direction of the strip body; the side rods of the treadmill are embedded in the second grooves of the strip body, so that the strip body is entirely covered on the top and two sides of the side rods.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The present invention adopts a method in which strip bodies made of foamed thermoplastic polyurethane elastic material are respectively mounted on two side rods, and the strip bodies are entirely covered on the upper surface and at least one side surface of the side rods; first grooves are respectively arranged on the opposite sides of the two strip bodies, and the two side edges of the running board are respectively inserted into the first grooves of the two strip bodies, and the length dimension of the strip bodies is greater than the length dimension of the running board, so that the elastic effect of the strip bodies can be used to cushion the entire running board. The structure of the present invention inserts both side edges of the running board as a whole on a strip body made of foamed thermoplastic polyurethane elastic material, so that the strip body made of foamed thermoplastic polyurethane elastic material elastically supports the running board. The excellent properties of the strip body made of foamed thermoplastic polyurethane elastic material can be used to realize elastic buffering of the entire running board, thereby avoiding damage to the runner's knee and ankle joints caused by hard contact when the runner steps on the running board; the strip body made of foamed thermoplastic polyurethane elastic material is wrapped on the upper and both side surfaces of the side rod, which can play a buffering effect on the side rod and eliminate the noise generated by the movement of the treadmill; because the side edge of the running board is inserted into the first groove of the strip body to realize the assembly between the running board and the support part, the assembly process is very simple, avoiding the disadvantage of the prior art that parts are needed to fix the running board, and has the characteristics of low production cost and convenient assembly.
