This material can only provide the practical erect length of the ruler itself from the standpoint, and does not excessively bend. It avoids deformation damage due to internal stress during the winding process. [Prior Art] Steel coils with recyclability have been commercialized for many years. A typical steel tape measure usually has a casing having a turn- ft with a strip of tape and a front end of the tape having a ruler hook. Usually on the housing = brakes are installed for the user's operation. The inner wire of the casing is a flat strip-shaped, Wei Lai-type elastic bodhisattva belt, the 匕=belt-end is fixed on the support shaft in the middle of the shell, and the other end is hooked on the runner. By screaming for the rotation of the reel to reel the tape with the required rotation of the tape, as for the ruler f 'usually the tail end will hook the vortex connected to the reel. The rotation is relatively fixed on the reel, borrowing The ruler γ of the runner will be wound up on the runner one by one. When the tape of the 2 steel tape measure is pulled out of the casing, its transverse section ^ structure is presented in a curved arc shape, which is called the concave-convex section arc when the tape is wound up in the casing. On the top, the tape is curved and has a flat shape. This is the so-called planar configuration of the tape. It is well known that the curvature profile of the concave-convex section when the tape is pulled out will form a rigidity of 1283291, which can provide the length of the tape itself to stand upright without falling apart due to the weight of the tape itself. The so-called ruler's standing degree. The conventional ruler has three kinds of concave and convex arc configurations. Referring to U.S. Patent No. 4,429,462, the convex shape of the tape can be a single arc; it can be an intermediate arc segment, and both sides Connect the straight line segment. Further, as described in U.S. Patent No. 6,324,769, the profile arc configuration may be an intermediate arc segment, and the arc segments of the same radius are attached to both sides. Most of the commonly used rulers have been designed, manufactured, and produced in three ways. The curved arc of the ruler, the rain 'even bends to the well-known, the curved shape of the concave and convex section of the ruler is more curved, or the deeper the curved curvature, the stronger the rigidity of the tape, the more standing, that is, the self-standing The length without collapse is longer. However, the more curved it will cause the difficulty of being flattened into a flat shape. Even if it is expected to some extent, the material dependence cannot bear the deformation stress of the flattened winding, which may cause damage or cracking of the material. These have been made in the patent '462, and even for the plane width of the tape, the length of the so-called commercial availability is presented, as shown in the following table.

只川’丨王的靦念來看，對於不同平 該是各有其上限值的存在。. 的尺帶，已經引起廣泛注意， 6 1283291 這是因為越寬的尺帶，其尺帶可以達到自我挺立而不崩落 的長度越長，也就是使用者再量測使用時，其尺帶挺立輕 射的半徑範圍更寬廣。另-個原因就是較寬的尺帶，其^ 刷版面的字體可以加大，更方便於量測時的讀取。本發明 的^的疋，針對寬度1”以上的尺帶，首先提出所謂適當 且實用的挺立疼上限的觀念出來。 其次，針對尺帶的凹凸剖面弧度構形，本發明定義一 • _平率，也就是尺料祕度的高度與f錄度的寬度 之比值，利用這個扁平率，本發明可以簡單預估出尺帶的 約略挺立度長度。最後針對各個不同平面寬度的尺帶，利 用挺立度上限的觀念，可以反推出尺帶凹凸剖面弧度構形 的扁平率之上限值，這個扁平率上限值可以用來界定，在 適田且只用性的條件之下，不同寬度之尺帶，其尺帶弧度 構形可以容忍承受的最大彎曲程度。 _ 【發明内容】 . 本發明的目的是，首先針對不同平面寬度之尺帶，提 出所謂適當且實用的挺立度上限值出來，使尺帶具有良好 的挺立效果，提供尺帶本身自我挺立、保持不崩落之實用 的挺立長度。一個簡單的觀念，越寬的尺帶平面寬度，可 以達成的貫用挺立度上限也越長，而且可以是成正比關 係。如果實用的挺立度上限值用Smax來表示；尺帶平面寬 度用L來表示，可以得出其關係式為細狀=1〇〇L。 本發明接下來的目的是，定義出一個可以衡量尺帶弧 1283291 度之、管曲程度的爲平率出來，藉此獲得一具有較佳回捲平 攤的效果，避免在收捲攤平過程中，因為内應力而變形受 損。尺帶弧度的扁平率可以定義為尺帶弧度獅之高度H 與寬度W的比值，用數學方式可以表示如下：α = h/w， 其中扁平率用4示，U尺帶弧度構形的高度，w是尺 f弧度構形的覓度。當扁平率〇比值越小，表示弧度構形 的軎曲私度越小，約接近於平面狀，當然挺立度也就越差； 當扁平率α比值越大，表示弧度構形的彎曲程度越大，越 遠離於平面狀，當然挺立度也就越佳。 接下來本發明内容實際進行一些不同寬度的尺帶弧度 構形之測試，本發明量測其尺帶之平面寬度L及厚度τ、 量測尺帶弧度構形之高度H及寬度w、量測其實際之挺立 度長度s、計算出扁平率α、以及挺立度s與扁平率α的 比值S/α。很顯然地一個結論，挺立度與扁平率的比值 約會等於400左右，可以表示為s = 4〇〇α。 最後，本發明内容利用挺立度與扁平率的比值s/a約 會等於400左右的關係，定義實用挺立度的上限值細狀會 相當於400倍的實用扁平率的上限值〇[ max。再套入關 係式Smax = l〇〇L，可得出α max = l/4這個關係式。 表示適當且實用的尺帶弧度構形，其扁平率不可以超過尺 帶平面寬度的1/4以上，否則此弧度構形極有可能會有過 度彎曲現象，從而導致尺帶不易被攤成平面狀，不易被一 圈圈收捲於轉輪上面。因此，滿足扁平率最大為amax = L/4的條件，可以保證此時之尺帶弧度構形，將具有相當 1283291 可靠的實用與經濟價值性。 【實施方式】 有關本發明所採用之技術、手段及其功效，兹舉一較 佳貫把例並配合圖式詳述如後，此僅供說明之用，在專利 申請上並不受此種結構之限制。 本發明的捲尺如圖一及圖二所示，通常包括有一個殼 • 體10,其内形成一個中空的穴Η，中間位置有個中心支軸 12，一個轉輪21安裝於此空穴π之内，並且可對中心支 軸12做迴轉運動。轉輪21的内部安裝一個扁平長條狀、 旋繞成渦型的彈簧帶22，此彈簧帶22 —端固定於殼體1〇 的中心支軸12上，另一端則勾掛固定於轉輪21上。 设體10具有一個開口 13，一條尺帶3〇需經過此開口 13而被拉出與收捲，而此部位之尺帶3〇下方，通常具有 一緩衝或降低摩擦的缓衝裝置14，此裝置可以讓尺帶3〇 ，被拉出或收捲時，具有緩衝保護或降低阻力之功能。尺帶 30收捲於殼體1〇内的轉輪21上時，是一圈一圈攤成平面 狀的，這是利用彈簧帶22可以提供足夠轉輪21迴轉多圈 的扭力來達成的。尺帶30的前端通常具有一個尺鉤， 此尺鉤31通常是用兩個以上的鉚釘32來固定，並且容許 尺鉤31可以對尺帶30進行極短距離的滑動。再者，殼體 10上通常會安裝一個剎車20,用來制動尺帶30的運動。 、尺帶30被拉出於殼體1〇外時，會自然的呈現彎曲弧 度狀，這就是所謂的凹凸剖面弧度構形33。此凹凸剖面弧 1283291 度構形33會形成相當的剛性，可以提供尺帶3〇自我挺立 ，一段之長度，而不會因為尺帶本身之重量而崩落，這就 是所謂的挺立度❶由於殼體開口 13的部位通常置放一個緩 衝或降低阻力的緩衝裝置14於尺帶下方，可以利用緩衝裝 置14的形狀改變來支撐尺帶3〇弧度，達到具有加強挺^ 度的效用。但是本發明所重視的是，尺帶30的凹凸剖面弧 度構形33跟挺立度的直接關連性，因此需要將這部份的因 素消除掉。 本發明疋義挺立度的量測方式如圖三所示，在一個平 台40上面有一個支軸41，其上安裝軸承42，尺帶3〇從殼 ，10拉出，並置放於此軸承42上面，讓尺帶保持挺立狀 恕。然後緩慢地推動尺帶30向前，此刻尺帶3〇會呈現自 然f曲的弧線向前延伸。接著保持此向前延伸的弧線在挺 立狀悲中，並使其弧線的最高點就在軸承42的支撐點上 面。缓慢地將尺帶30往前推進時，當尺帶3〇達到某個延 1申出去之長度S時’尺帶30會無法保持自我挺立狀而崩 洛’此刻的尺帶30延伸出去的弧線長度s就是本發明定義 的挺立度長度。 參考圓四所示，通常尺帶3〇的弧度構形犯是由中間 圓弧段35，兩邊外侧加上相等且對稱的兩侧圓弧段％組 成。中間圓孤段35之半徑可用R1表示，展開角度可_ 表示；兩侧圓弧段34之半徑可用R2表示，展開角度可職 來表示。再者，此時的弧度構形33之寬度可以用¥來表示， 高度可以用Η來表示。 1283291 常用的三種尺帶30之弧度構形33皆可以用這種方式 來表示，當R1 = r2時，即是單圓弧之構形；當R1 >尥 时，即疋中間圓弧加上兩側也是圓弧之構形；當Μ =⑺ 時’兩侧圓孤變成直、線，即是中間圓弧加上兩側直線的構 形。值得注意的是，一般是不用R1 <R2的，因為這樣中 間圓弧弯曲度較小，兩侧圓弧的、彎曲度較大，不是挺立度 過低，就是尺帶30不易被攤成平面收捲起來。 當尺帶30被一圈圈地收捲於轉輪21上時，其凹凸剖 面弧度構形33會被攤成平面狀，這就是所謂的尺帶30之 平面構形36，如圖五所示，此時尺帶3〇平面的寬度可用[ 來表示，厚度可用T表示。 本發明是針對一種可收捲的鋼捲尺，其尺帶30的平面 見度在1以上，提出實用挺立度長度的上限觀念。我們 首先來看現在常用的平面寬度是i，，的尺帶，我們測試挺 立度，度分別是95”，100”，及1〇5”的尺帶，發現挺立 _ · ^95”的尺帶，其收捲鮮的效果相當理想，提供適當的 彈貝扭力即可，這也是市面上最常見到的挺立度值。而挺立 度100的尺帶，其收捲攤平的抵抗性增強，必須再增加 一些彈簧扭力，才能將尺帶順利地攤平於轉輪21上面收捲 起來，其難度已經增加不少。再看挺立度105，，的尺帶，其 尺帶弧度構形33的彎曲性更大，反折尺帶發現，尺帶弧度 構形33谷易因為應力瞬間變化而變形受傷。再者，其所需 攤成平面構形36的力量更大，結果就是尺帶3〇收捲於轉 輪21上面時，其尺帶一圈圈收捲的平整性不佳，尤其是總 11 1283291 25 #尺帶，轉輪21在旋轉運動的過程中會晃 择/1、、’、°要降低這樣的效果，f要彈簣22提供甚多額外 曰^、扭力’但無法保證可以完全消除收捲平整性不佳的 。因此結論就是Γ的尺帶，其挺立度超過，時， =發生收捲不平整的問題，或者是需要額外增加甚多的 貫扭力來克服收捲不平整的_，這樣的挺立度其實用 性與經濟性的價值甚低。 ^ 接下來我們來看平面寬度是125”的尺帶，測試挺立 ^的長度分別是120，，，125”，及130，，的尺帶。同樣地現 不，越低的挺立度其所需彈簧的扭力越低，挺立度120” 的尺π ’其收捲攤平的狀況很理想。挺立度125，，的尺帶， 必須要用更強更長的彈簧提供扭力，才能讓轉輪可以順暢 的轉動收捲尺帶。但是挺立度13()”的尺帶，即使已經提 供相當大的彈簧扭力’仍然無法紐其尺帶的收捲平整 性’而且反折尺帶也會讓弧度構形造成損傷。簡單的壯褕 就是，對於平面寬度^ 25”的尺帶，其挺立度的長^好 『要超過125” ’否則尺帶會有反折受傷及收捲不易的問 題0 由上述兩個實例可以得知，對於丨，，寬度的尺帶，其 挺立度長度應該不能大於100” ；對於125，，寬度的^ 其挺立度長度最好不要大於125” ，這樣可以&證尺 f具有相當的實用性與經濟性價值。推論可知：不同平面 寬度的尺帶，其實用的挺立度長度最高上限值，約會等於 尺帶平面寬度的100倍。 胃 ' 12 1283291 本發明定義實用的挺立度上 · 別平面寬度用L來表示，可以得出2 SmX來表示；尺帶 ，塑尺、其闕係式為L 〜曰尺▼挺立度長度的因素有极多，例 色 的凹凸剖面孤度構形33、尺帶3的 ^ 尺帶別最前端的尺釣3J重量等等，其中=^及 是尺帶30的剖面弧度構形幻 泠…沈 的尺嫌如甘1 ^ ^ 承所週知，弧度越彎曲 其挺立賴高，因此本㈣ Φ 可以用來!估出挺立度的長度，以設計= 全=f ▼3 0孤度4來’達到驗設制發的時 間與金錢，具體展現出經濟性與實祕的價值。 —本，明於此再提出—個4平率的觀念，參考圖四所 不:尺娜度的扁平率可以定義為尺帶 =1與寬度[的比值’用數學方式可以表示為一 β /、中扁平率用α表示，H是尺帶.彎曲弧度的高度，w 疋尺帶3(M#曲弧度的寬度。⑽匕值越小，表示弧度構形泊 ㈣曲程度越接近於平面，其抵抗攤成平面狀的剛性越 弱田/、、、:挺立度越差，值越大，表示弧度構形％的弯Judging from the mourning of the king of the river, the existence of the upper limit is different for different levels. The tape has attracted a lot of attention, 6 1283291. This is because the wider the tape, the longer the tape can reach the self-standing without falling, the longer the tape is when the user measures it again. The range of light shots is wider. Another reason is that the wider tape can increase the font size of the brushing surface, which is more convenient for reading during measurement. According to the invention of the present invention, for the ruler having a width of 1" or more, the concept of a suitable and practical upper limit of the standing pain is first proposed. Secondly, for the curvature profile of the concave and convex section of the tape, the present invention defines a _ flat rate. That is, the ratio of the height of the size of the ruler to the width of the f-record. With this flatness, the present invention can easily estimate the approximate length of the tape. Finally, for the tape of different plane widths, the stand is used. The concept of the upper limit can be used to deduct the upper limit of the flatness of the curved profile of the concave and convex section. This upper limit of the flattening rate can be used to define the different widths under the conditions of suitable and only useability. The belt has a curvature configuration that can tolerate the maximum degree of bending. _ [Summary of the Invention] The object of the present invention is to first propose a so-called appropriate and practical upper limit of the erection for different tape widths of different plane widths. The ruler has a good erecting effect, providing a practical erect length that the sling itself is self-standing and does not collapse. A simple concept, the wider the tape plane Degree, the upper limit of the uniformity that can be achieved is longer, and it can be proportional. If the practical upper limit is expressed by Smax; the width of the ruler is expressed by L, the relationship can be Fineness = 1〇〇L. The next object of the present invention is to define a flatness of the degree of curvature of the tube with an arc of 1,283,291 degrees, thereby obtaining a better rewinding effect. In the process of winding and leveling, the deformation is damaged due to internal stress. The flatness of the arc of the ruler can be defined as the ratio of the height H of the ulnar arc to the width W, which can be expressed mathematically as follows: α = h /w, where the flatness ratio is shown as 4, the height of the U-scale with the curvature configuration, and w is the curvature of the curvature configuration of the ruler f. The smaller the ratio of the flatness ratio, the smaller the distortion of the curvature configuration. Close to the plane shape, of course, the lower the degree of standing; the greater the ratio of the flatness ratio α, the greater the degree of curvature of the curvature configuration, and the farther away from the plane, the better the degree of standing. The content actually carries some different widths With the test of the curvature configuration, the present invention measures the plane width L and the thickness τ of the tape, the height H and the width w of the gauge with the curvature configuration, measures the actual length of the straightness s, and calculates the flatness ratio. α, and the ratio S/α of the erection s to the flatness ratio α. It is clear that the ratio of the erection to the flatness is about 400, which can be expressed as s = 4 〇〇 α. Finally, the content of the present invention is utilized. The ratio of the s/a ratio of the standing degree to the flatness ratio is equal to about 400. The upper limit value defining the practical erection degree is equivalent to the upper limit value of the practical flatness ratio of 400 times max[max. Then the relationship Smax is inserted. = l〇〇L, the relationship of α max = l/4 can be obtained. Indicates the appropriate and practical ruler curvature configuration, the flatness ratio can not exceed 1/4 of the width of the tape plane, otherwise the arc structure There is a possibility that the shape may be excessively bent, so that the tape is not easily spread into a flat shape, and it is not easy to be wound up on the runner by a circle. Therefore, satisfying the condition that the flatness ratio is maximally amax = L/4 can guarantee the curvature configuration of the ruler at this time, and will have a reliable practical and economic value of 1283291. [Embodiment] The technology, the means and the functions thereof used in the present invention are described in detail with reference to the drawings, which are for illustrative purposes only, and are not subject to such patent application. Structural limitations. As shown in FIG. 1 and FIG. 2, the tape measure of the present invention generally includes a casing body 10 having a hollow hole therein, a central support shaft 12 at the center, and a wheel 21 mounted on the cavity π. Within the range, the center support shaft 12 can be rotated. A flat strip-shaped, spiral-shaped spring strip 22 is mounted on the inside of the runner 21, and the spring strip 22 is fixed at the end to the central support shaft 12 of the housing 1〇, and the other end is hooked and fixed to the runner 21 on. The body 10 has an opening 13 through which a strip 3 is pulled and retracted, and the tape 3 below the strip is usually provided with a buffering or friction reducing buffer 14 The device can make the tape 3 turns, and it has the function of cushioning protection or reducing resistance when being pulled out or wound up. When the tape 30 is wound on the runner 21 in the casing 1 , it is formed in a circle and a circle, which is achieved by the spring belt 22 providing sufficient torque for the runner 21 to rotate a plurality of turns. The front end of the tape 30 typically has a ruler hook 31 which is typically secured by more than two rivets 32 and which allows the ruler hook 31 to slide the tape 30 a very short distance. Further, a brake 20 is usually mounted on the housing 10 for braking the movement of the tape 30. When the tape 30 is pulled out of the casing 1 , it will naturally show a curved arc shape, which is the so-called concave and convex curve curvature configuration 33 . The concave and convex section arc 1283291 degree configuration 33 will form a considerable rigidity, and can provide the tape 3 〇 self-standing, the length of a section, without falling apart due to the weight of the tape itself, which is the so-called standing degree ❶ due to the shell The portion of the opening 13 is usually placed with a buffering or lowering resistance buffering device 14 below the tape. The shape change of the cushioning device 14 can be used to support the tape 3 arc to achieve the effect of reinforcing the stiffness. However, the present invention is directed to the fact that the curvature profile 33 of the tape 30 is directly related to the stiffness, and therefore it is necessary to eliminate this factor. The measuring method of the present invention is shown in FIG. 3. On a platform 40, there is a support shaft 41 on which a bearing 42 is mounted, and the tape 3 is pulled out from the casing 10 and placed on the bearing 42. Above, let the ruler stay upright. Then the tape 30 is slowly pushed forward, at which point the tape 3〇 will appear to extend forward in the arc of the natural f curve. The arc that extends forward is then held in an upright manner and the highest point of the arc is above the support point of the bearing 42. Slowly push the ruler 30 forward, when the tape 3 〇 reaches a certain length of the extension 1 S, the tape 30 will not be able to maintain its own self-standing and collapsed. The length s is the length of the erection defined by the present invention. Referring to the reference circle 4, the arc configuration of the ruler with 3 turns is usually composed of an intermediate circular arc segment 35, and the outer sides of the two sides are combined with equal and symmetrical circular arc segments on both sides. The radius of the intermediate circular segment 35 can be represented by R1, and the expansion angle can be represented by _; the radius of the arc segments 34 on both sides can be represented by R2, and the expansion angle can be represented by the duty. Furthermore, the width of the curvature configuration 33 at this time can be represented by ¥, and the height can be represented by Η. 1283291 Commonly used three kinds of ruler 30 curvature configuration 33 can be expressed in this way, when R1 = r2, it is a single arc configuration; when R1 > ,, that is, the middle arc plus The two sides are also the configuration of the arc; when Μ = (7), the two sides of the circle become straight and straight, that is, the middle arc plus the straight lines on both sides. It is worth noting that R1 <R2 is generally not used, because the curvature of the intermediate arc is small, the curvature of the arc on both sides is large, and the degree of curvature is not too low, that is, the tape 30 is not easily spread into a plane. Get it up. When the tape 30 is wound on the runner 21 in a circle, the concave and convex curvature configuration 33 is spread into a plane shape, which is the planar configuration 36 of the tape 30, as shown in FIG. At this time, the width of the 3〇 plane of the tape can be expressed by [to indicate that the thickness can be represented by T. SUMMARY OF THE INVENTION The present invention is directed to a retractable steel tape measure having a plan view of the tape 30 having a flatness of 1 or more, and proposes an upper limit of the practical length of the stand. Let us first look at the tape widths that are commonly used today, i, and, we test the standing degree, the degrees are 95", 100", and 1〇5" tapes, and find the tape with _ · ^95" The effect of the reeling is quite ideal, and it can provide the appropriate spring torsion force, which is the most common standing value on the market. The tape with a standing degree of 100, the resistance of the winding flattening is enhanced, and some spring torque must be added to smoothly level the tape on the runner 21, and the difficulty has been increased. Looking at the ruler with a standing degree of 105, the curvature of the ruler with the curvature of the ruler 33 is greater, and the rule of the ruler is found that the curvature of the ruler is easily deformed due to the instantaneous change of the stress. Moreover, the force required to form the planar configuration 36 is greater, and as a result, when the tape 3 is wound on the runner 21, the flatness of the tape is not good, especially the total 11 1283291 25 #尺带,The wheel 21 will select /1, ', ° in the process of the rotary motion to reduce the effect, f to the magazine 22 to provide a lot of extra 曰 ^, torque 'but can not be guaranteed to be completely Eliminate poor flatness of the winding. Therefore, the conclusion is that the sturdy ruler has a higher degree of standing, when, = the problem of uneven winding occurs, or the need to add a lot of additional torque to overcome the unevenness of the winding _, the practicality of such a standing degree The value with economics is very low. ^ Next, let's look at the tape with a plane width of 125". The length of the test is ± 120,, 125", and 130, and the tape is 130. The same is not the case, the lower the standing degree, the lower the torsion force of the required spring, and the erecting degree of 120" of the standing degree is ideal. The condition of the winding level is ideal. The standing degree of 125, the tape must be used more. Stronger and longer springs provide torque for the runner to smoothly rotate the take-up tape. However, the 13-degree-long tape, even if it already provides a considerable spring torque, is still unable to roll up the tape. Sexuality and the folding of the ruler will also cause damage to the curvature configuration. The simple sturdy is that for a ruler with a width of ^ 25", the length of the erection is better than "125". Otherwise, the tape will have a problem of reversing the wound and the winding is not easy. It is known that for 丨, the width of the tape, its length should not be greater than 100"; for 125, the width of its length should not be greater than 125", so that the ruler f has considerable Practicality and economic value. It is inferred that the tape widths of different plane widths have the highest upper limit of the practical length of the standing, and the date is equal to 100 times the width of the tape plane.

Try to wind the Nq. 6, 7 ruler ^ 3 于 on the runner 21 and find that such a curvature configuration 33 is basically entangled in a circle, because the degree of curvature is really too large, it is quite difficult It is spread out into a flat shape. The ratio of the above table tells the invention by the touch: the ratio of the standing degree to the flattening ratio is equal to about 4〇〇, which can mean S = 400cx〇” ” Any empirical formula has the existence of its error. The ratio of the ratio S/cc is equal to about 400, and the error also exists. There are three main reasons for the error. The first point is the weight of the ruler 31, and the heavier the hook 31 is shorter. The lighter fishing 31 has a longer standing. The second point is the thickness of the tape 3〇. The relationship between the current tape and the thickness of the disease material is about G.G_, '~0.0053”. The thickness of the tape steel taken in the present embodiment is about 〇 · 〇〇43,, ~〇〇〇49". The thicker the steel, the better the ability to maintain the curvature of the curve, that is, the stiffness can be longer. The third point is the hardness of the tape 30. Similarly, the harder = steel can provide more rigidity, that is, the longer the standing. In fact, 1283291 according to the experience of the present invention, these three factors affect the degree of standing, the maximum effect of the difference is about m, so the ratio of the flatness of the flatness ratio S/cx summed up above is equal to 働 is equivalent Has a reference value ^.

Next, we discuss the curvature configuration of the other profile. The arc configuration shown in Figure 4 above is basically based on the intermediate arc segment 35, which is composed of two arc segments 34 or a straight line. This is because the arc is the most basic geometric element. It is also the easiest line to defend. But in addition to this, there are actually many continuous curves that can be used. Arcs are geometrically continuous continuous curves, so other common quadratic curves, such as ellipse, secret, and hyperbola, can also be shouted. . Referring to Figure 6, the arc segment method, the curvature or the curvature half is a continuous change, the radius of curvature of Figure 6a is changed from small to large, and Figure 6b is changed from large to small. It is obvious that Figure 6a is more practical. This shows that for the curvature configuration of the ruler, the optimal geometric configuration method is still the smallest radius of curvature of the middle part, and then gradually enlarged to both sides. The focus is on using k-times curves, or other continuous-differentiable curves, and the flattening rate is followed by another phenomenon. The previously described ruler 3 turns arc configuration is basically bilaterally symmetric, but due to the tape 30 The thickness ΤΓ is very thin. In the actual production process, the curvature of the ruler is easily changed, that is, the arc is not a true arc, and the straight line is sometimes easy to bend. Referring to Figure 7, 15 1283291 theoretical arc configuration 33 should be symmetric 曰 deviation 'hypothetical deviation of the curve 3 = also U is the width of the tape to the bottom of the deviation distance is W1, the degree of ^ ^ structure = 33 The a 4. When the field deviation is too large, the tape 30 will be unbalanced and will cause difficulty in recycling. Basically, the ratio of the width f to the width of the arc of f curvature /w should be less than "' Otherwise, the combination of ΐΓ=Γ° is actually biased, and does not affect the estimate of the ratio of the estimated length. The content of the present invention is summarized by the flatness ratio. Firstly, the present invention is directed to different plane widths: the second application of the upper limit of the degree of standing is proposed, and the invention can be used to define the ratio of the flat ratio. The degree of curvature of the arc i 'and then the ratio of the length of the straightness to the flatness is about 僧ς ' can be expressed by S = 4 〇〇 α, that is, the upper limit of the practical erection = the copper ratio The practicality is the upper limit of the flat rate of camphor. The set of ❿ 糸 ❿ 糸 ^ can know the relationship 〇 ^ = Μ. The present invention can be used to have a constant plane I degree of at least 1" tape width L, practical erection Limit
