New Description: [New Technology Alliance] This creation is about a treadmill, especially one that has a buffered shock absorption layer on the bottom edge of the running belt to reduce noise and reduce sports injuries. [Previous technology] According to the current social changes, people are busy and busy, resulting in relatively reduced exercise time. Therefore, indoor exercise equipment is widely welcomed by everyone; among them, the treadmill is the most popular fitness equipment. Sub-press, the main components of the treadmill, as shown in the first and second figures, include a body (11), a frame (12) disposed on the body before and after the frame (12) (13) ), (14)' and a deck (16) 'to support the running belt (15) around the front and rear rollers (丨3), (14). However, the pedal (16) is made of hard materials such as wood, so it does not have the shock absorption capacity when running, just like the feeling of stepping on the concrete floor is 'very uncomfortable' and the vibration is loud and easy to cause reaction. There are sports injuries. Therefore, the design of the improved treadmill to have a cushioning shock absorption effect is generated, as shown in the third figure, which is provided with a soft buffer layer (17) above the pedal (16) for forming a shock absorption shock. The effect of this type of patent is found in the patent application of the international application PCT WO 03/031664 A1. However, it is checked that the buffer layer (17) is fixed on the surface of the pedal (16) and is located on the bottom edge of the running belt (15), when the running belt (15) is around the front and rear rollers (13), ( 14) When turning, the bottom edge surface is continuously displaced, and the surface friction resistance with the stationary buffer layer (17) not only makes the running belt (15) not smooth, but more importantly, this friction The force will gradually wear down the soft buffer layer (17) from the surface of the surface -3-, resulting in a limited service life, which is the largest loss. Further, the fourth figure shows a patent of US Patent No. 6,077,200, which discloses a plurality of rubber pads (18) between the pedal (16) and the frame (12). The bottom of the frame body (12) is provided with a cushioning elastic member (19). In addition, it is known that treadmills are provided with elements such as an Air bag or a hydraulic cylinder on the underside of the pedal, and the cushioning shock absorbing effect is achieved by the members. However, it is impossible to effectively eliminate the force of the pedal rebound, especially when the running speed is increased, there is no time to react and resolve, so there is still room for improvement. [New content] The main purpose of this creation is to provide a cushioning shock absorbing structure for treadmills, which is to solve the problems caused by the use of treadmills in sports, so that it has direct shock absorption effect and is comfortable to use. And no noise, and it is not easy to cause sports injuries such as ankles and knee joints. Another object of the present invention is to provide a cushioning shock absorbing structure of a treadmill, wherein the cushioning shock absorbing layer is passively displaced synchronously with the running belt, so that the contact surface does not cause slip friction, and the running belt can smoothly run, and It ensures the service life of the shock absorbing layer. In order to achieve the above objectives, the technical means adopted by the present invention comprises: a body; a frame is disposed on the body, and has longitudinal rods on both sides; a support plate is fixed between the two bodies, And a front wheel and a rear end position of the two poles are correspondingly provided with a first roller set; and a running belt is disposed around the outer circumference of the first roller set; wherein: the corresponding inner side of the first roller set further comprises a second roller set is disposed, and the front and rear roller sets of the second roller set are respectively located at positions before and after the support plate; and the second roller set is wound around a buffer shock absorbing layer in the shape of a rotary belt. The upper surface of the cushioning shock absorbing layer is located on the inner edge surface of the running belt. When the user steps on the running belt, the buffering shock absorbing layer is forced to be driven by the running belt, so that the buffering shock absorbing layer always has a section. The area is moved on the support plate, and the cushion provides a direct shock absorbing interface for the running belt. [Embodiment] First, referring to FIG. 5 to FIG. 8 , a preferred embodiment of the present treadmill (20) includes: a body (21) including an unpowered running type, or The electric running type with the motor, or the machine for rehabilitating walking, etc., can be implemented without any details. A frame (22) is attached to the body (21) and has longitudinal members (221) on both sides. A support plate (26), comprising a wooden core board, a composite board, etc., is fixed between the two rod bodies (221), and the front and rear ends of the two rod bodies (221) are correspondingly provided with a first a roller set (23), that is, it includes a front roller (231) and a rear roller (232); in addition, if it is an electric type, the front roller (231) is additionally connected to the transmission component and the body (21) The motor (not shown) is connected and driven by it. A running belt (25) is wound around the periphery of the first roller set (23). The above structure is a prior art (Prior Art), which is a necessary component of a general treadmill, and is not a patent of the present invention. M382834 and 'the improved feature of the present invention is that: the corresponding inner side of the first roller set (23) further comprises a second roller set (24), and the second wheel set front and rear rollers (241), (242 Between the support plate (26) and the rear end position; and the second roller set (24) is provided with a shock/impact absorber (27) in the shape of a slewing belt, The shock absorbing layer (27) includes either a rubber/EVA foam material or a PU foam, or a combination thereof, but is not limited thereto, that is, an equivalent material may be used. The combination of the shock absorbing layer (27) and the second roller group (24) is the same as the combination of the running belt (25) and the first roller group (23). The second roller set (24) is designed such that the cushioning shock absorbing layer (27) removes the conventional system from being fixed on the surface of the supporting pedal, but exhibits dynamics, that is, the surface above the cushioning shock absorbing layer (27) is located. The inner edge of the running belt (25), when the running belt (25) is activated, is rotated clockwise as shown in the seventh and eighth figures. At this time, if the foot has not been stepped on, the cushioning shock (27) is The stationary belt (25) is idling and a gap (S) is formed therebetween. Therefore, the bottom edge surface of the running belt (25) does not wear the cushioning shock absorbing layer (27) at this time. When the user's foot is stepped on the running belt (25), 'using the gravity of the body, the bottom edge of the running belt (25) is forced against the upper surface of the cushioning shock absorbing layer (27), so that both Between the ninth and tenth figures, 'the formation of a push interface (28) for active and slave relationships, so that when the running belt (25) is stepped on the foot, the buffer shock absorbing layer (27) can be simultaneously driven. In the clockwise direction, the inner edge surface of the running belt does not rub against the upper surface of the shock absorbing layer (27) to be worn, thereby increasing its service life. In the M382834, the cushioning shock absorbing layer (27) is dynamic and constantly displaced, so after a period of use, it does not form a concave surface at the fixed point of the pedal position, so it is very smooth and comfortable when running or stepping on.
此外，本創作之緩衝吸震層（27)係由撓韌性材質所構 成，使其得以連接成一迴轉帶型態，例如：橡膠/EVA發泡材、 PU發泡體等，但不限定於此，舉凡具有緩衝吸震功能的材料 及形式皆可實施。再者，其一較佳實施例，係如第八、十圖 所示，包括在其内緣面設有一财磨層（271)。該财磨層（271) 包括由樹脂、高強力帆布、PVC或強化塑膠等撓性材所製成， 使其在位移時可以降低與支撐板（26)上表面的摩擦力。 是以，本創作藉助上揭技術特徵，使得在使用跑步機 時，具有直接的緩衝吸震效果，不僅倍感舒適且不易受到運 動傷害，並因降低摩擦而可使跑步帶順暢運轉，故可提昇使 用壽命之功效者。 綜上所述，本創作所揭示之構造，為昔所無，且確能達 到功效之增進，並具可供產業利用性，完全符合新型專利要 件，祈請貴審查委員核賜專利，以勵創新，無任德感。In addition, the cushioning shock absorbing layer (27) of the present invention is composed of a flexible material, and is connected to a rotary belt type, for example, a rubber/EVA foam material, a PU foam body, etc., but is not limited thereto.
