M328184 八、新型說明： 【新型所屬之技術領域】 本創作係關於一種運用凹凸扣合定位並在受到強力拉 扯時其扣合處可解扣之貓用的安全項圈。 【先前技術】M328184 VIII. New Description: [New Technology Area] This creation is about a safety collar for cats that use the embossed snap-fit and can be unfastened when the button is pulled strongly. [Prior Art]
一般寵物用的項圈可具有多種功能，例如：讓人一見 即知「我不是流浪狗（描）」；可放入主人的連絡地址或 電話，以在寵物走失時有助尋獲，特別是在RF ID晶片未 發展之前尤具效果；可扣上鏈子或皮帶以限制寵物之活動 範圍以及踏狗；可作為裝飾之用；可結合防蚤劑以驅除跳 蚤或蜱等體外寄生蟲，即所謂之Γ防蚤項圈」；亦可裝入 電極，在狗吠叫或貓***對其通以電流，以警示並阻止其 繼續發出打擾鄰居的聲音，即所謂的「電擊項圈」…等等。 現有技術之項圈，參見第六及七圖所示，其項圈帶（圖 中未不）用於插接扣合的兩端分別設有一公扣（4〇)及一母 扣（50)，其中公扣（4〇)前端形成有一倒鈎（41)，後端為一 與項圈帶相互固定的彈性舌片（42)，母扣（5〇)上形成有垂 直相通的一插孔（51)及一壓孔（52)，壓孔（52)底部内凹成 型有一容置通道（54)，且於插孔（51)與壓孔（52)間形成有 一方向與倒鈎（41)相對的對立倒鈎（5 3 )，倒鈎（41)與對立 倒鈎（53)上分別形成有一垂直於公、母扣（4〇, 之軸向 的後翼部（411，531)，及一與後翼部（411，531)相接且朝 公、母扣（4〇, 50)之前端傾斜向下的前斜翼部（412, 532)。 當公扣（40)之倒鈎（41)***母扣（50)之插孔（51)内 5 M328184 時，受其内的導引構造（圖中未示）導引而前進，使倒鈎 (41)之前斜翼部（412)相對於對立倒鈎（53)之前斜翼部 (532)而沿其逐漸進入容置通道（54)中，並使彈性舌片（42) 形成彎折，直到兩倒鈎（41，53)之前斜翼部（412,532)相互 脫離後，彈性舌片（42)的彈性恢復力使得倒鈎（41)與對立 倒鈎（5 3 )之後翼部（411，5 31)相互卡掣，此時將公扣（4 〇 ) 與母扣（50)朝反方向拉扯並無法使公扣（4〇)與母扣（5〇)相 互鬆脫，必須要從壓孔（52)將倒鈎（41)下壓至容置通道（54) 中，直到兩後翼部（411,531)不相接觸，方可進一步使倒 鈎（41)再沿插孔（51)退出母扣（5〇)，進而使公扣（4〇)與母 扣（50)相互鬆脫。 對於狗而言，其跳躍能力不大，故活動模式純屬二度 二間平面，裝設這種項圈沒有問題，但貓的活動方式係部 份為三度空間式，其可輕易跳上二、三公尺或由更高的高 度躍下，且又擅於爬樹、爬牆，因此帶有此種項圈的貓， 於其行動間項圈很容易被週遭的突出物鈎掛住，以致於勒 住頸部吊掛在半空中而造成窒息死亡，或者因項圈無法與 大出物脫離而造成饑餓死亡，故現有技術之項圈於使用上 確有其安全問題。 【新型内容】 有鑑於前述現有技術的缺點，本創作設計一種貓用安 王項圈，其可在項圈兩端受到超過一臨界值之反方向作用 力4，使扣合處相互脫離，避免貓受困於項圈中。 要用簡單的機械設計達成此目的，則插接扣合部的倒 6 M328184 鈎與對立倒鈎之後翼部與公、母扣之軸向間需形成一小於 90度的適當角度，方能在略施力下使公、母扣相互脫離， 關於此點，茲先做一簡單分析： 參見第四及五圖所示，假設後翼部與公、母扣之軸向 間的角度為一 0角，則當公、母扣分別受到一反方向之作 用力F時，則倒鈎與對力倒鈎之後翼部相互壓抵的力量可 分解為兩向量：General pet collars can have a variety of functions, for example: let people know at a glance that "I am not a stray dog"; can be placed in the owner's contact address or phone number to help find the pet when it is lost, especially in the pet The RF ID chip is particularly effective before it is developed; it can be chained or strapped to limit the range of activity of the pet and the dog; it can be used as a decoration; it can be combined with an anti-caries agent to remove ectoparasites such as fleas or cockroaches.

The front end of the male buckle (4〇) is formed with a barb (41), the rear end is a resilient tongue piece (42) fixed to the collar band, and a female socket (5〇) is formed with a vertical connection (51). And a pressing hole (52), the bottom of the pressing hole (52) is concavely formed with a receiving passage (54), and a direction is formed between the insertion hole (51) and the pressing hole (52) opposite to the barb (41). The opposite barbs (5 3 ), the barbs (41) and the opposite barbs (53) respectively form a rear wing portion (411, 531) perpendicular to the male and female buckles (4 〇, the axial direction, and a The rear wing portions (411, 531) are in contact with each other and are inclined toward the front end of the male and female buckles (4〇, 50). The front oblique wing portions (412, 532). When the male buckle (40) is barbed (41) When inserting 5 M328184 in the socket (51) of the female buckle (50), it is guided by the guiding structure (not shown) in the inner side, so that the oblique wing portion (412) of the barb (41) is opposite to Opposite the barb (53) before the slanting wing (532) and gradually along it The elastic tongue (42) is bent into the accommodating passage (54), and the elastic tongue (42) is bent until the two inclined hooks (41, 53) are separated from each other, and the elastic tongue (42) is elastically restored. The force causes the barbs (41) and the opposite barbs (53) to engage with each other (411, 5 31). At this time, the male buckle (4 〇) and the female snap (50) are pulled in the opposite direction and cannot be made. The male button (4〇) and the female button (5〇) are loose from each other, and the barb (41) must be pressed down from the pressing hole (52) into the receiving passage (54) until the two rear wings (411, 531) If there is no contact, the barbs (41) can be further removed from the socket (51) by the female button (5), thereby releasing the male button (4〇) and the female button (50). The jumping ability is not large, so the activity mode is purely two-two planes. There is no problem in installing this collar, but the cat's activity mode is partly three-dimensional, which can easily jump two or three meters or Jumping from a higher altitude, and being good at climbing trees and climbing walls, cats with such collars are easily hooked by the surrounding protrusions in their action collars, so that they can live The hangs in the air and causes suffocation to die, or the stagnation and death caused by the collar being unable to detach from the large objects, so the prior art collar has its own safety problems in use. [New content] In view of the aforementioned shortcomings of the prior art This creation design is a cat's Anwang collar, which can be subjected to a force in the opposite direction of more than a critical value at both ends of the collar, so that the buckles are separated from each other, preventing the cat from being trapped in the collar. To use a simple mechanical design To achieve this goal, the inverted 6 M328184 hook of the insertion and the hook and the axial direction of the wing and the male and female buckles after the opposite barbs need to form an appropriate angle of less than 90 degrees, so that the utility can be made with a slight force. The mother button is separated from each other. For this point, we should first make a simple analysis: See the fourth and fifth figures, assuming that the angle between the rear wing and the axial direction of the male and female buckles is a zero angle, then When the female buckle is subjected to a force F in the opposite direction, the force of the barb and the wing after the barb is pressed can be decomposed into two vectors:
Fe=Fcos0 :平行於倒鈎之後斜翼部的力；Fe=Fcos0: the force parallel to the oblique wing after the barb;
Fp=Fsin0 :垂直於倒鈎之後斜翼部的法向力； 其中’ Fe會使倒鈎相對於對立倒鈎滑動，進而使兩倒 鈎之後翼部相互脫離，但此L尚受到一界面摩擦力的阻 礙，其須大於该摩擦力方能產生滑動，假設兩倒鈎之後翼 4之間的靜摩擦係數為V ( V值經常小於1 )，則摩擦力 為#Fsin0 ,因此，當 1>匕時，則 Fc〇s0 > "Fsin 0，即 cos 0 > v Sin 0，意即 c〇t 0 > "; 由此可看出，理論上，兩倒鈎扣合後，能否拉開而相 互脫離僅與夾角0及靜摩擦係數#有關，而與作用力f無 關，但實際上，此係假設倒鈎與對立倒鈎分別為一不會變 形的絕對剛體，且施於倒鈎與對立倒鈎上的作用力F正好 在一直線上，意即沒有力矩，但實際上，倒鈎之彈性舌片 係以彈性材料製成，而且作用力卩也絕不會正好在同一直 線上因此即使在cot 0 g #的情況下，只要加大力量， 則方面力矩變大，有利於將倒鈎扭轉而從對立倒鈎扭 開另方面彈性舌片產生的彈性變形加大，有利於使倒 7 M328184 鈎彎曲，而由對立倒鈎滑脫，因此只要選擇適卷 材質，便可使項圈的兩倒鈎在所要的臨界作用力 ^ 下相互鬆 脫。 理想的臨界作用力大約是略小於佩帶項圈 、吗< I田的體 重，如此，當貓被吊掛住時，即使不掙扎，其體重的重力 也足以使項圈鬆脫，例如二、三個月大的小貓，臨界拉力 " 可設為0· 5公斤，而成貓約可設為2至4公斤，此臨界拉 力比貓抓癢時踢蹬的力量大，因此不會因此而輕易鬆脫\ • 至於適當的角度範圍，由以上公式可看出，當 度，# = 0·8時，cot0 = 1 >〇·8，換言之，Fe恆大於摩 擦力，只要受到任一作用力F，均會使項圈鬆脫，而當Θ =60度，# = 〇·8時，則c〇t0与〇 58<〇 8，此種角度下 可能需要很大的作用力才能使彈性舌片變形，並使公扣由 母扣中鬆脫’因此，實用的角度約在5〇度至55度之間。 本創作的優點在於，其除了可如先前技術使兩倒鈎以 _ 前斜翼部相對，讓公扣沿母扣之前斜翼部而進入其中，並 進步藉彈性舌片之彈性恢復力而讓兩者之後斜翼部相對 卡擎’以使公扣扣合於母扣内部，使項圈可簡單扣合之外， 當公扣與母扣受到超過一臨界值之反方向作用力拉扯時， 亦可使公扣沿母扣之後斜翼部移動並進一步脫離母扣以打 開項圈’如此一來，當裝有此安全項圈的貓用前腳洗臉、 用後腳抓痕武& 廣3相互玩耍而碰到或踢到項圈時，其扣合處因 力未達到臨界值而不會隨意鬆開，但當項圈被突出物鈎 掛住時’該隻1苗只要用力掙扎，因其本身的重量及外力將 8 M328184 超過所設定的臨界值，便可使公扣與母扣相互鬆脫分離而 脫離困境’避免貓受到吊掛而窒息，&因無法脫離而造成 饑餓死亡，且由於此種插扣的接合方式可容許較大的誤 差，而且製造成本低廉’因此不需用複雜的有限元素數值 刀析作電腦模擬以設計其角度，只要做一系列樣品，角度 由45度至度之間每隔2度至3度’㈣測試導致鬆脫 的臨界拉力，若再進一步用内插法還可得到更精確的理想 角度’以供大小不同的|苗使用。 【實施方式】 參見第一至三圖所示，為一本創作之安全項圈，其一 如先前技術包括有一項圈帶（1〇)，及分別固設於項圈帶（1〇) 兩端的一公扣（20)及一母扣（3〇)，其中該公扣（2〇)前端形 成一倒鈞（21 )，後端為一與項圈帶（1 〇 )相互固定的彈性舌 片（22)，該母扣（3〇)上形成有垂直相通的一插孔（31)及一 壓孔（32)，壓孔（32)底部内凹成型有一容置通道（35)，且 於插孔（31)與壓孔（32)間形成有一方向與倒鈎（21)相對的 對立倒鈎（33)，倒鈎（21)與對立倒鈎（33)上分別成型有一 朝其前端傾斜向下的前斜翼部（211,331)，及一與前斜翼 部（211，331)相接而朝項圈帶（10)方向傾斜向下的後斜翼 部（212, 332)，其特徵在於： 後斜翼部（212, 332)與公、母扣（20, 30)之軸向間形成 有一約50度至55度的夾角（23, 34)。 當公扣（20)之倒鈎（21)***母扣（30)之插孔（31)内 時，倒鈎（21)之前斜翼部（211)相對於對立倒鈎（33)之前 M328184 斜翼部（3 3 1 )而沿其逐漸進入容置通道（3 5 )中，並使彈性 舌片（22)形成彎折，直到兩倒鈎（21，33)之前斜翼部 (211，331)相互脫離後，彈性舌片（22)的彈性恢復力使得 倒鈎（21)與對立倒鈎（33)之後斜翼部（212, 332)相對卡 掣，讓公扣（20)卡合於母扣（30)中。 而該後斜翼部（212, 332)與公扣（2〇)及母扣（3〇)之轴 向間的夾角（23, 34)，使得當公扣（2〇)與母扣（3〇)在受到 超過一臨界值之反方向作用力時，倒鈎（21)與對立倒鈎（33) 之後斜翼部（21 2, 332)會相對滑動，並導致彈性舌片（22) 彎曲變形而將倒鈎（21)下壓至容置通道（35)，且進一步進 入插孔（31)中，使公扣（20)與母扣（30)之前斜翼部 (211，331)相對並滑動，直到公扣（2〇)脫離母扣，如 此一來裝没此安全項圈的貓便能順利脫離，避免因項圈帶 (10)被週遭之突出物釣掛住而產生危險。 由於這種公、母扣（20, 30)可廉價製造，且其容許誤 差可以很大，因此並不須作複雜的數值分析來求出最後的 0角，只需從45度至60度間做幾個樣品，例如：48度、 51度、54度、57度，母隔3度做一個，測試其臨界拉力， 再用内插法及可得到。 又，在以上設計中，倒鈎（21)與對立倒鈎（33)的後斜 翼部（212 ’ 332)都是平滑的面’其皆可進一步加工為粗糙 的表面，例如做喷砂處理，或橫向設有淺肋齒，以增加其 表面的摩擦阻力，如此便可在45度或甚至比托度更小的 斜度達成所要的臨界拉力值。 M328184 【圖式簡單說明】 第一圖為本創作之立體外觀圖。 第二圖為本創作部分元件之立體分解圖。 第三圖為本創作部分元件於卡合狀態之側視剖面圖。 第四突為本創作之施力狀態示意圖。 第五圖為本創作之施力狀態示意圖。 第圖為現有技術部分元件之立體分解圖。 第圖為現有技術部份元件於卡合狀態之側視剖面 I 圖。 (20)公扣 (211)前斜翼部 (22)彈性舌片 (30)母扣 (32)壓孔 (331)前斜翼部 (34)夾角 (40)公扣 (411)垂直翼部 (42)彈性舌片 (51)插孔 (5 3 )對立倒鈎 (532)斜翼部 【主要元件符號說明 (10)項圈帶 (21)倒鈞 (212)後斜翼部 (23)夾角 (31)插孔 (3 3)對立倒鈎 I - (332)後斜翼部 (35)容置通道 (41)倒釣 (412)斜翼部 (5 0)母扣 (52)壓孔 (531)垂直翼部 (54)容置通道 11Fp=Fsin0: normal force perpendicular to the oblique wing after the barb; where 'Fe will slide the barb relative to the opposite barb, so that the wings are separated from each other after the two barbs, but this L is still subjected to an interface friction The force obstruction, which must be greater than the friction force, can produce a slip. Assuming that the static friction coefficient between the wings 4 after the two barbs is V (the V value is often less than 1), the friction force is #Fsin0, so when 1> When, Fc〇s0 >"Fsin 0, ie cos 0 > v Sin 0, meaning c〇t 0 >"; It can be seen that, in theory, after the two barbs are fastened, Whether it is pulled apart and separated from each other is only related to the angle 0 and the static friction coefficient #, but is independent of the force f, but in fact, it is assumed that the barb and the opposite barb are respectively an absolute rigid body that does not deform, and is applied to the inverted body. The force F on the hook and the opposite barb is exactly on the straight line, meaning that there is no torque, but in fact, the elastic tongue of the barb is made of elastic material, and the force is never exactly on the same line. Therefore, even in the case of cot 0 g #, as long as the force is increased, the moment becomes larger, there is In order to twist the barb and twist it from the opposite barb, the elastic deformation of the elastic tongue is increased, which helps to bend the inverted 7 M328184 hook and slip off the opposite barb, so that only the suitable material can be selected. The two barbs of the collar are released from each other under the desired critical force ^. The ideal critical force is about a little less than wearing the collar, and the weight of the I field, so that when the cat is hung, even if it is not struggling, the weight of the weight is enough to loosen the collar, for example, two or three. The month old kitten, the critical pull force can be set to 0. 5 kg, and the cat can be set to 2 to 4 kg. This critical pull force is stronger than the kicking force when the cat scratches it, so it will not be loose.脱 \ · As for the appropriate range of angles, it can be seen from the above formula that when degrees, # = 0·8, cot0 = 1 > 〇 · 8, in other words, Fe is greater than friction, as long as any force F , both will loosen the collar, and when Θ = 60 degrees, # = 〇 · 8, then c 〇 t0 and 〇 58 < 〇 8, this angle may require a large force to deform the elastic tongue And make the male buckle loose from the female buckle. Therefore, the practical angle is between 5 degrees and 55 degrees. The advantage of the present invention is that, in addition to the prior art, the two barbs are opposite to each other with the front slanting wing portion, and the male buckle is inserted into the slanting wing portion before the female buckle, and the elastic restoring force of the elastic tongue is improved. After the two, the oblique wing is opposite to the damper' so that the male buckle is fastened to the inside of the female buckle, so that the collar can be simply buckled, and when the male buckle and the female buckle are pulled by a force exceeding a critical value in the opposite direction, The male buckle can be moved along the female buckle and then further separated from the female buckle to open the collar. Thus, when the cat with the safety collar is used to wash the face with the forefoot, the back foot scratches the Wu & When hitting or kicking the collar, the buckle does not reach the critical value and does not loosen at will, but when the collar is hooked by the protrusion, the 1 seedling only struggles, because of its own weight and external force. If 8 M328184 exceeds the set threshold value, the male buckle and the female buckle can be loosened and separated from each other to prevent the cat from being suffocated by suffocation, & hunger death due to inability to detach, and due to such a buckle The way of joining can tolerate larger errors Poor, and low manufacturing cost' Therefore, it is not necessary to use complex finite element numerical analysis for computer simulation to design its angle, as long as a series of samples, the angle is from 45 degrees to 2 degrees to 3 degrees between degrees (four) test The critical pulling force that leads to loosening, if further interpolation is used, a more precise ideal angle can be obtained for use by different sizes of seedlings. [Embodiment] As shown in the first to third figures, it is a created safety collar, which has a loop (1〇) as in the prior art, and a male fixed at both ends of the collar (1〇). a buckle (20) and a female buckle (3〇), wherein the front end of the male buckle (2〇) forms a inverted raft (21), and the rear end is an elastic tongue (22) fixed to the collar belt (1 〇). The female buckle (3〇) is formed with a vertical insertion hole (31) and a pressing hole (32). The bottom of the pressing hole (32) is concavely formed with a receiving passage (35), and is inserted into the socket (35). 31) forming an opposite barb (33) opposite to the barb (21) with the pressing hole (32), and the barb (21) and the opposite barb (33) are respectively formed with a downward slope toward the front end thereof a front oblique wing portion (211, 331), and a rear oblique wing portion (212, 332) that is in contact with the front oblique wing portion (211, 331) and inclined downward toward the collar band (10), wherein: The wings (212, 332) form an included angle (23, 34) between the axial direction of the male and female snaps (20, 30) of about 50 to 55 degrees. When the barbs (21) of the male buckle (20) are inserted into the insertion holes (31) of the female buckle (30), the front bevel (211) of the barbs (21) is inclined relative to the opposite barbs (33) before the M328184 The wing portion (3 3 1 ) gradually enters into the accommodating passage (35), and the elastic tongue piece (22) is bent until the two barbs (21, 33) are anteriorly inclined (211, 331) After being detached from each other, the elastic restoring force of the elastic tongue (22) causes the barbs (21) to be opposite to the oblique wing portions (212, 332) after the opposite barbs (33), so that the male buckle (20) is engaged with In the female buckle (30). The angle between the rear inclined wing portion (212, 332) and the male buckle (2〇) and the female buckle (3〇) is (23, 34), so that when the male buckle (2〇) and the female buckle (3) 〇) When the force is applied in a direction opposite to a critical value, the barbs (21) and the opposite barbs (33) slide relative to each other and cause the elastic tongues (22) to bend. Deformation and pressing the barb (21) down to the receiving passage (35), and further entering the socket (31), so that the male buckle (20) is opposite to the front oblique wing portion (211, 331) of the female buckle (30) And slide until the male buckle (2〇) is removed from the female buckle, so that the cat without the safety collar can be smoothly detached, avoiding the danger that the collar belt (10) is caught by the surrounding protruding objects. Since the male and female buckles (20, 30) can be manufactured inexpensively, and the tolerance can be large, it is not necessary to perform complicated numerical analysis to find the final 0 angle, only from 45 degrees to 60 degrees. Do a few samples, for example: 48 degrees, 51 degrees, 54 degrees, 57 degrees, the mother is 3 degrees to do one, test its critical tensile force, and then use interpolation and available. Moreover, in the above design, the barbs (21) and the rear inclined wings (212' 332) of the opposing barbs (33) are smooth surfaces, which can be further processed into rough surfaces, for example, sandblasted. Or shallow rib teeth are provided laterally to increase the frictional resistance of the surface, so that the desired critical tension value can be achieved at a slope of 45 degrees or even less than the support.
