Description
本發明係關於一施力偵測裝置;該裝置係運用牛頓第三定律(反作用力回應於作用力)之原理,以裝設於其上之荷力錠與扭力計,即時偵測其上運動者動作施力輸出與重心變化之過程。故本發明有助於與運動相關之科學研究與訓練。 The invention relates to a force detecting device; the device uses the principle of Newton's third law (reaction force in response to force) to load the force spindle and the torque meter thereon, and instantly detect the motion thereon. The process of applying force output and changing the center of gravity. Therefore, the present invention contributes to scientific research and training related to exercise.
先前試圖滿足該目的之裝置均採獨立踏板設計,而由板上之偵測儀器,如壓力計(gauge meter)或荷力錠(load cells)等,結合訊號顯示器或數據收集與分析軟體,分別顯示或測量運動者動作(如高爾夫揮桿等)過程中,身體平衡、重心分佈、重量移動與雙足施力等狀態。 Previous attempts to meet this goal have been designed with independent pedals, and on-board detection instruments, such as gauge gauges or load cells, combined with signal displays or data collection and analysis software, respectively During the display or measurement of the movements of the athletes (such as golf swings, etc.), the balance of the body, the distribution of the center of gravity, the movement of the weight, and the exertion of the feet.
早期如1965年2月9日公告之美國專利公報(美專利)第3169022號(Kretsinger君)中披露之簡易裝置,由燈泡顯示揮桿觸球時何足所負重量為最。後續裝置如1992年6月2日公告之美專利第5118112號(Bregman,et al.等君)、1992年9月29日公告之美專利第5150902號(Heisler君)、1995年5月30日公告之美專利第5419562號(Cromarty君)與2002年6月11日公告之美專利第6402635號(Nesbit,et al.等君)中披露者,則可決定各足上之總和重 量,但無法提供身體重心之數據,而該踏板於使用中會有滑開的可能。 The simple device disclosed in the U.S. Patent Publication No. 3,609,022 (Kretsinger Jun), published on Feb. 9, 1965, shows the weight of the weight of the ball when the ball is displayed. Subsequent devices such as US Patent No. 5118112 (Bregman, et al.), published on June 2, 1992, US Patent No. 5150902 (Heisler Jun), published on September 29, 1992, and the beauty of the announcement on May 30, 1995 Patent No. 4,541, 956 (Cromarty Jun) and US Patent No. 6,402,635 (Nesbit, et al., et al.), published on June 11, 2002, may determine the total weight of each foot. The amount, but can not provide the data of the body's center of gravity, and the pedal may slip open during use.
這些裝置中,特別是Heisler君與Cromarty君與另一2000年3月21日公告之美專利第6039658號(Cecchin君)者,雖可決定各足上之總重量,但無法分辨於足部各不同部位,如足尖與足跟或內外側等,之分佈。2011年5月24日公告之美專利第7946928號(Mooney君)者雖具上述功能(測量足部各不同部位之受重分佈),但因踏板分立並可移動,因此無法測量身體重心。2014年12月23日公告之美專利第8915149號(Berme君)者之相疊踏板設計則可計算身體重心狀態。 Among these devices, especially Heisler Jun and Cromarty Jun and another US Patent No. 6039658 (Cecchin Jun) announced on March 21, 2000, although they can determine the total weight of each foot, they cannot distinguish between different feet. The distribution of parts, such as the toe and the heel or the inside and outside. Although the US Patent No. 7946928 (Mooney Jun) announced on May 24, 2011 has the above functions (measuring the weight distribution of different parts of the foot), the center of gravity cannot be measured because the pedals are separated and movable. The stacking pedal design of the US Patent No. 8915149 (Berme Jun) announced on December 23, 2014 can calculate the state of gravity of the body.
總之,先前技術不論以個別足部或雙足受重方式為依據,皆僅能揭露運動者身體平衡、重心分佈、重量移動與雙足施力等狀態;然而事實上,幾乎所有運動除了水平與上下移動外,更包括身體的扭動或轉動,這也是先前各項裝置所無法測得者。本創新發明運用牛頓第三定律原理,裝設荷力錠與扭力計於相疊盒板平台之設計,即可畢其功於一役。 In short, the prior art, based on the individual foot or the weight of the two feet, can only reveal the athlete's body balance, center of gravity distribution, weight movement and biped force; however, in fact, almost all movements except horizontal In addition to moving up and down, it also includes the body's twisting or turning, which is also undetectable by previous devices. The innovative invention uses Newton's third law principle to install the design of the load-bearing ingot and the torque meter on the stacking plate platform, and then it can be completed.
與運動相關之科學研究與訓練,有賴可靠監測儀器提供與記錄精確數據以供分析,例如高速攝影或影片技術。然而該等技術只能提供肢體移動而非動力輸出方面的數據,因此,運動動力偵測裝置之研發至關重要。 Scientific research and training related to sports relies on reliable monitoring instruments to provide and record accurate data for analysis, such as high-speed photography or film technology. However, these technologies can only provide data on limb movement rather than power output. Therefore, the development of motion motion detection devices is crucial.
運動者動作之達成,除了身體各部位神經、肌肉與骨骼之協同作用外,還需仰賴足部(或身體)與地面間的摩擦力;這也是為何於滑溜表面難以動作,甚或易因重心不穩而跌倒,以及運動鞋底或運動場地表面講 究防滑與有效阻力等的原因。其背後的物理理論基礎不外乎牛頓運動第三定律(Newton’s Third Low):任何作用(action)皆伴隨一等量但方向相反之反作用(reaction);例如步行是靠足部向後施力於地面,再由地面所伴隨的反作用力推動前進,而移動力道則取決於其與地面間的摩擦力(或摩擦係數)。向上彈跳是靠腿部曲膝下蹬,再由地面所伴隨的反作用力推動向上而成;線性力如此,扭轉力亦然。因此,若能利用該原理測量身體與地面之間的力道或摩擦力,即可反映身體的施力(或動力輸出)總和狀態。 In addition to the synergy between the nerves, muscles and bones of various parts of the body, the movement of the athletes also depends on the friction between the feet (or the body) and the ground; this is why it is difficult to move on the slippery surface, or even because of the center of gravity. Stable and fall, as well as the surface of the sports sole or sports field Study the reasons for slip resistance and effective resistance. The physics theory behind it is nothing more than Newton's Third Low: any action is accompanied by an equal amount of opposite reaction; for example, walking relies on the foot to force the ground backwards. Then, the reaction force accompanying the ground pushes forward, and the moving force depends on the friction (or coefficient of friction) between it and the ground. The upward bounce is made by bending the knees of the legs and then pushing up by the reaction force accompanying the ground; the linear force is so, and the torsional force is also the same. Therefore, if the principle can be used to measure the force or friction between the body and the ground, the state of the body's force (or power output) can be reflected.
如同先前裝置設計,將力感裝置,如荷力錠(load cell),置於足底或足底所踏之平板(施力板或簡稱力板)下方,即可測得身體垂直方向施力的力道(或vertical force,如無施力狀態即為該足所受之體重);故將荷力錠分別置於雙足所踏(或承載運動者)長方形力板之四角下方,即可同步測得垂直力總和與重心分佈(或distribution of center of gravity,如重心向受力多者偏移,重心居中則受力均等,重心不變則受力不變)。 As in the previous device design, a force device, such as a load cell, can be placed under the plate (the force plate or simply the force plate) on which the sole or the sole of the foot is pressed, and the vertical force of the body can be measured. The force force (or vertical force, such as the weightless state is the weight of the foot); so the force spindle is placed under the four corners of the rectangular force plate of the foot (or bearer), then you can synchronize The vertical force sum and the center of gravity distribution (or the distribution of center of gravity) are measured, such as the center of gravity shifts to the force, the center of gravity is equal, and the center of gravity does not change.
有鑒於此,若將荷力錠置於力板側邊四周之各個中點,則理應測得該板之水平施力(horizontal force,如左移則右側錠受力,前移則後側錠受力等,依此類推);因此如圖式所示,本發明將力板置於一恰可容納該板之淺盒(荷力盒或簡稱荷盒)內,並將荷力錠分別置於該盒四壁之中點與盒內(即力板下方)四角,則當該盒處於固定狀態下,力板(或身體總和)之水平與垂直施力即可分別同步測得。 In view of this, if the load pin is placed at each midpoint around the side of the force plate, the horizontal force of the plate should be measured. If the left side moves, the right side of the ingot is forced, and the left side of the ingot is forced. Forced, etc., and so on; therefore, as shown in the figure, the present invention places the force plate in a shallow box (load box or simply a box) that can accommodate the board, and separates the load spindles In the middle of the four walls of the box and the four corners of the box (ie, below the force plate), when the box is in a fixed state, the horizontal and vertical force of the force plate (or the sum of the bodies) can be measured separately.
推而廣之,旋轉力或扭力也可如法泡製。同樣如圖式所示,若能將力板荷盒組合再套疊於一大小相當之平板(扭力板或簡稱扭板)上,盒底與扭板中心以一扭力計銜接,其間襯以固定分佈於四個角落之滾動鋼珠 以為支撐並去除摩擦力,則當扭板處於固定狀態下,荷盒(或身體總和)之扭力即可由扭板上之扭力計測得。 In a nutshell, the rotational or torsional forces can also be brewed as usual. As shown in the figure, if the force plate and the combo box combination can be stacked on a flat plate (torque plate or abbreviated plate), the bottom of the box and the center of the torsion plate are connected by a torque meter, and the lining is fixedly distributed. Rolling steel balls in four corners In order to support and remove the friction, when the torsion plate is in a fixed state, the torque of the cartridge (or the sum of the bodies) can be measured by the torque meter on the torsion plate.
最後,如圖式所示,為加強平台結構與穩定,力板上方與扭板下方分別各以鎖鏍,將防護與強化邊框固定於荷盒上方與下方。扭板底部四角則設有可獨立調整高度之防滑底腳,以穩固平台並調整其水平狀態。 Finally, as shown in the figure, in order to strengthen the structure and stability of the platform, the upper part of the force plate and the lower part of the torsion plate are respectively locked with locks, and the protection and the reinforcement frame are fixed above and below the lotus box. The bottom corners of the torsion plate are provided with non-slip feet that can be independently adjusted to stabilize the platform and adjust its horizontal state.
此一利用牛頓第三定律,結合上下堆疊力板、荷盒與扭板之簡易平台設計,輔以巧妙裝設之荷力錠與扭力計,即可即時同步偵測其上運動者各項(如垂直、水平與扭轉)加總施力過程與重心分佈變化,不但充分填補所有先前發明之缺憾與不足,更為此等領域之發明做出革命性突破。 This uses Newton's third law, combined with the simple platform design of the upper and lower stacking force plates, the box and the torsion plate, supplemented by the ingeniously mounted load spindle and torque meter, which can instantly detect the athletes on the move ( Such as vertical, horizontal and torsion), the total force application process and the distribution of the center of gravity, not only fully fill the gaps and shortcomings of all previous inventions, but also make a revolutionary breakthrough in the invention of these fields.
再者,本發明(或其背後原理)不但適用於所有與地面接觸之定點運動,例如一記高球揮桿、棒球揮棒、網球或桌球揮拍、起跑、起跳(跳遠、投籃或跳水)、起腳(踢球)、拋擲、出拳與踢腿等等,也可用於移動運動(如跑步或步行過程中各個步閥可分別踩踏於一系列平台),因此應用甚廣,幾可涵蓋各式球類、田徑、體操、健身、復健、舞蹈、武術及搏擊等肢體動作。 Furthermore, the present invention (or its underlying principles) applies not only to all fixed-point sports in contact with the ground, such as a high-ball swing, a baseball swing, a tennis or billiard swing, a start, a jump (long jump, a shot or a dive), Feet (kicking), throwing, punching and kicking, etc., can also be used for mobile sports (such as stepping on a series of platforms during running or walking), so it can be used in a wide range of applications. Body movements such as ball, track and field, gymnastics, fitness, rehabilitation, dance, martial arts and fighting.
不僅如此,本發明也可依運動類型、強度與施力方式,搭配相應平台尺寸或材質,以及調整或更換力感裝置之裝設點位、感測範圍與數據收集頻率。一旦結合數據收集、分析與紀錄電腦軟硬體及顯示器之即時回饋,當可提供動作間或與參考數據之比較與檢討。最後,本發明尚具構造精簡、易於製造組裝及維修保養、便於攜帶與使用等優點。 Moreover, the present invention can also match the size or material of the corresponding platform according to the type of exercise, strength and force application, and adjust or replace the installation position, sensing range and data collection frequency of the force sensing device. Once combined with the data collection, analysis and recording of computer hardware and software and the immediate feedback of the display, it can provide a comparison or review of the action or reference data. Finally, the present invention has the advantages of simple structure, easy assembly, maintenance, and portability and use.
