Abstract: An exercise machine which provides back-and-forth movement and vibration is revealed. The exercise machine includes a base and a loading platform in which two sides of a middle portion thereof are pivotally connected to the base. A motor, a first transmission device, and a second transmission device are mounted in the base. The motor drives the first transmission device which further drives the second transmission device. The second transmission device which is connected to the loading platform drives the loading platform to move back and forth while the first transmission device makes the base to have vibration. Thereby the exercise machine generates vibration and back-and-forth movement, allowing users to experience both motions.

Abstract: A method for manufacturing a massage wear-resistant treadmill deck and a finished product thereof are provided. The method includes step 1: providing a mold, the mold having a plurality of cavities thereon, a wear-resistant material being injected into the cavities of the mold; step 2: placing a deck in the mold so that the wear-resistant material is bonded to a surface of the deck to form a plurality of massage protrusions on the deck; and step 3: demoulding the deck from the mold, the surface of the deck being formed with the massage protrusions to form the massage wear-resistant treadmill deck. A wear-resistant layer having the massage protrusions is first formed in the mold, and then the deck is placed into the mold to bond with the wear-resistant layer to form the massage wear-resistant treadmill deck. The manufacturing cost is reduced and the manufacturing mobility is improved.

Abstract: A horse riding exercise machine is not only compact in structure but also easy to be assembled and disassembled. When in use, a second N-shaped connecting rod and/or a return member are provided to achieve a labor-saving effect for exercise. Through a compact structure and the detachable connection of a bolt, when the horse riding exercise machine is not used, the bolt can be loosened so that a rear support base can be pushed toward a front support base to close up, thereby reducing the storage space to facilitate the storage.

Abstract: A method of making a buffer board of a treadmill includes a sizing step, a shade drying step, a presetting step, a clamping and heat-pressing step, a cooling step, and a die opening step. The method can easily make the desired buffer board adapted to the treadmill and can only change different dies to make buffer boards with different structures when an upper die and a lower die of a die set provide protrusions, flat surfaces or depressed surfaces, thereby reducing the manufacturing cost.

Abstract: A buffer board structure of a treadmill includes bamboo layers made by attaching bamboo sheets side by side, a bottom surface of which is adhered by a membrane layer whereby the bamboo sheets are firmly stuck on the membrane layer. Each membrane layer has an upper and lower faces respectively stuck between the bamboo layers. The bamboo sheets of each bamboo layer face the same juxtaposing direction, whereas bamboo layers juxtaposed lengthways provide a better buffer. By setting one membrane layer between two bamboo layers, contact faces of the bamboo layers and the membrane layer adhered together become smoother, and an adhesive fills in a gap more evenly. A slip resistant layer is stuck on the top bamboo layer. A smoother buffering effect and a stable juxtaposition are obtained when the bamboo layers are trodden to prevent the breakdown of buffer relations between the bamboo sheets and the membrane layers.
