Description
本創作係涉及一種橢圓機曲柄調整定位結構，特別是指一種提供結構結合緊密且構造穩定，並可根據使用者使用橢圓機時調整曲柄施力臂長度之實用創新型態設計者。 The present invention relates to an elliptical crank adjustment positioning structure, in particular to a practical innovative design that provides a tight structure and a stable structure, and can adjust the length of the crank arm according to the user's use of the elliptical machine.
按，一般的曲柄傳動結構主要係應用於傳遞動力和省力作業，其常被運用於自行車、運動健身器材(如橢圓機)等設備中。 According to the general crank transmission structure, it is mainly used for transmitting power and labor-saving work, and it is often used in bicycles, sports fitness equipment (such as elliptical machines) and other equipment.
而單純就針對運動健身器材的對橢圓機(ellipticals)來說，橢圓機也稱為交叉訓練機(cross-trainer,X-trainer)，用於模擬爬樓梯、走路，或跑步等運動，簡要的介紹一下橢圓機可結合跑步機與腳踏車的優點，以站姿進行全身性的運動。由於雙腳同時固定在橢圓機上，左右腳受力的時間各一半，能夠減少膝關節的衝擊力，降低受傷的機率。 For the elliptical machines (ellipticals) for sports and fitness equipment, the elliptical machine is also called cross-trainer (X-trainer), which is used to simulate climbing stairs, walking, or running, etc. Introduce the elliptical machine to combine the advantages of treadmills and bicycles to perform a general movement in a standing position. Since both feet are fixed on the elliptical machine at the same time, the left and right feet are forced to take half of the time, which can reduce the impact force of the knee joint and reduce the chance of injury.
但單純一般的橢圓機通常具有踏板供使用者踩踏，而針對一般的橢圓機的運動機構的缺點在於曲柄長度不可改變，因在作動過程中無法依照適用於人體所運動之模式，特別是人體關節部位，如腳腕處在不同位置處的不同施力方式而進行調整曲柄施力臂的大小，進而導致使用者在利用該曲柄傳動結構工作或運動時非常費力並易於疲勞，且曲柄的圓型運動軌跡與人體關節部位的橢圓形運動軌跡不符，是故該類曲柄運動機構仍 常會導致人體關節部位受傷。 However, a simple elliptical machine usually has a pedal for the user to step on, and the disadvantage of the movement mechanism for a general elliptical machine is that the length of the crank cannot be changed, because the movement is not in accordance with the mode suitable for the movement of the human body, especially the human joint. The position, such as the different force-applying manners of the ankle at different positions, adjusts the size of the crank-applying arm, thereby causing the user to work and move with the crank transmission structure, which is very laborious and easy to fatigue, and the crank is round. The trajectory of the movement does not match the elliptical motion trajectory of the joint part of the human body. Therefore, the crank motion mechanism of this type is still Often it can cause joint injuries in the human body.
而有相關業者開發出如台灣專利M403355「橢圓運動機的揚昇裝置」，其該技術特徵在於基座具有一間隔地位於地面上之基架，且基架用以固設於橢圓機機體；該揚昇架樞設於該基座，且可相對該基座偏轉而與地面形成一仰角；該斜度控制裝置包括有一設置於該揚昇架且具有一伸縮桿之掣動器，以及一舉伸裝置，其一端樞接於該伸縮桿之自由端，另一端抵靠於地面並可沿地面滑移，藉由上述結構組合後能夠改變橢圓運動機之踏板運動軌跡的傾斜度。但是其實不然，因其運動軌跡(行程)的跨距，亦即運動時使用者雙腳的距離(pace length)，仍為固定。由於使用者的身高差異性大，固定行程跨距無法適合全部的使用者，進而導致訓練的效果被降低且有可能造成人體關節部位受傷等諸多問題。 A related manufacturer has developed a lifting device such as the Taiwanese patent M403355 "Elliptical exercise machine", which is characterized in that the base has a base frame spaced apart on the ground, and the base frame is fixed to the elliptical machine body; The lift frame is pivotally disposed on the base and is deflectable relative to the base to form an elevation angle with the ground; the slope control device includes a retainer disposed on the lift frame and having a telescopic rod, and The extension device has one end pivoted to the free end of the telescopic rod, and the other end abuts against the ground and can slide along the ground. The combination of the above structures can change the inclination of the pedal movement track of the elliptical exercise machine. However, it is not the case that the span of the motion trajectory (stroke), that is, the distance between the feet of the user during exercise, is still fixed. Due to the large difference in height of the user, the fixed stroke span cannot be adapted to all users, and the effect of the training is lowered and the joints of the human body may be injured.
有鑑於上述一般橢圓機無法提供使用者能夠操作使用橢圓機時，能夠調整曲柄施力臂長度後，達到亦符合人體工學原理，更具有效保障人體的健康和安全減少膝關節的衝擊力，降低受傷的機率並且提供使用者舒適操作使用之目的。是以。創作者以從事相關行業多年之經驗，積極研究開發，終有本創作『橢圓機曲柄調整定位結構』之產生。 In view of the fact that the above elliptical machine cannot provide the user with the operation of the elliptical machine, the length of the crank arm can be adjusted to achieve the ergonomic principle, and the health and safety of the human body can be effectively ensured to reduce the impact of the knee joint. Reduce the chance of injury and provide users with the purpose of comfortable operation. Yes. The creators have been engaged in research and development for many years in the relevant industries, and finally have the creation of the "elliptical crank adjustment positioning structure".
