Description

嬰兒承載裝置用的安全扣具及其方法
本發明係關於嬰兒承載裝置用的安全扣具及其方法。
一般地為滿足法規對小孩乘座某一嬰幼兒產品之安全性要求。目前供小孩乘座之產品上均設置有相應的安全扣具用於束縛乘座的小孩,以確保其乘座的安全性。習知市面上有諸多現有扣具行銷,在這類技術中所利用之扣具,大多利用按鈕向下壓按公扣(腰扣),使公扣(腰扣)移離開與母扣的卡合而達到釋鎖的目的。其按鈕的復位方式是利用公扣舌片***。如美國第6711790號專利案所揭示,其採用按壓式來釋鎖的安全扣具,這種連接方式一旦被誤碰按鍵,就有可能解除了連接,這對於一些場合是非常危險的。
因此,能提供一種採用前推式的安全扣具,其不易釋鎖,且安全性有保證,更能有效地保證公扣與肩帶扣之間的卡合仍為目前存在的需求。
有鑑於此,本發明提供一種採用前推式的三五方向安全扣具,扣具不易釋鎖,安全性有保證,且還能有效地保證公扣與肩帶扣之間的卡合。扣具釋鎖後公扣之間的卡合也便利。
依據本發明一實施例,該安全扣具包括一肩帶扣、一腰帶扣及一母扣。其中該母扣設有適於接受該肩帶扣與該腰帶扣***的開口,以與該腰帶扣相卡合。該腰帶扣與該肩帶扣為沿一平面***該開口,該母扣更包括一推鈕,該推鈕可沿該平面的一滑動方向活動,以抵觸並推出該腰帶扣。
本發明另一實施例亦提供一種嬰兒承載裝置,其包括一承載體,一肩帶,及一腰帶。該肩帶的一端設有一肩帶扣,該腰帶的一端設有一腰帶扣。該肩帶扣與該腰帶扣可與一母扣卡合。其中該母扣設有適於接受該肩帶扣與該腰帶扣***的開口,以與該腰帶扣相卡合。該腰帶扣與該肩帶扣為沿一平面***該開口,該母扣更包括一推鈕,該推鈕可沿該平面的一滑動方向活動,以抵觸並將該腰帶扣自該母扣的該開口推出。
圖1及圖2為繪示依據本發明一實施例之安全扣具。此種安全扣具亦通稱“三五方向”安全扣具。如圖1、2所示,安全扣具1包括母扣11、兩腰帶扣12、兩肩帶扣13及一推鈕14。母扣11具有一正表面11a。每一腰帶扣12包含一開口121,其用以接受腰帶穿過其中。肩帶扣13亦設有開口131,用以接受肩帶穿過其中。腰帶扣12可與肩帶扣13相連接,以構成扣合組15。每一扣合組15以可滑動的方式與母扣11扣合。
圖3為繪示安全扣具1的分解圖,圖4則繪示安全扣具1的組裝狀態圖。如圖3及4所示,肩帶扣13上分別設置有一卡合凹孔132,相對應地,腰帶扣12上分別設置有一卡合凸柱122,卡合凸柱122為分別與卡合凹孔132相卡合,以使腰帶扣12與肩帶扣13相連接。方向A為腰帶扣12與肩帶扣13***或脫離母扣11的滑動方向。方向B則為推鈕14的活動方向,以抵觸並推出腰帶扣12與肩帶扣13。方向A與方向B位於同一平面,其與母扣11的正表面11a平行。
圖5為繪示母扣11與肩帶扣13的結合方式。如圖5所示,肩帶扣13上還分別設置有一卡合肋133,其例如為T形或其它形狀。相對應地,母扣11上端部左右兩側向內分別設置有一卡合槽111,其例如為T形或其它符合卡合肋133的形狀。藉由***卡合肋133至卡合槽111內,可將肩帶扣13與母扣11相卡合。
圖6為繪示母扣11與腰帶扣12的結合方式。請參考圖3、4及6,兩腰帶扣12上分別設置有卡合肋123、舌片124,其中卡合肋123可為L形或任何其它形狀,舌片124中則設有卡合孔125。對應地,母扣11上設置有容置孔112,母扣11內部對應卡合孔125則凸設有卡合凸台113及對應於卡合肋123形狀的複數個肋條。藉由卡合肋123及舌片124透過容置孔112***至母扣11中,使腰帶扣12上的卡合孔125進一步與母扣11內的卡合凸台113卡合,可實現兩腰帶扣12與母扣11的卡合,並藉由肋條的輔助以穩固腰帶扣12與母扣11的結合關係。
圖7為繪示腰帶扣12、肩帶扣13與推鈕14的結構圖。如圖3、4、7所示,推鈕14左右兩側分別設有助推條141,助推條141上設置有助推面1411及助推面1412,其中助推面1411及1412可具有傾斜度。當腰帶扣12完成***後,助推面1412位於舌片124的下方。推鈕14的後端設有推動部142,供使用者施加推動力,以解開安全扣具。推鈕14的前端則設有兩具撓性的回位觸條143,其在推鈕14往前移動時將抵觸母扣11的一內側壁(圖8)。當外加於推鈕14上的推動力被去除時,藉由回位觸條143的彈力使推鈕14回位。
圖8為繪示腰帶扣12、肩帶扣13與母扣11卡合後的局部立體圖,圖9則繪示腰帶扣12、肩帶扣13與母扣11卡合後的剖面圖。如圖8、9所示,當相連接的腰帶扣12、肩帶扣13***母扣11後,腰帶扣12的舌片124先與卡合凸台113抵接,使舌片124略為上彎,待腰帶扣12、肩帶扣13完全***時,舌片124藉由撓性材質之恢復作用而回復原本之外形,卡合凸台113將穿過腰帶扣12上的卡合孔125與之卡合,以鎖住腰帶扣12(及肩帶扣13)於母扣11中。當腰帶扣12、肩帶扣13與母扣11卡合後,助推面1412位於舌片124的下方,助推面1411則位於鄰近舌片124的外緣126。
當使用者欲解開安全扣具時,將透過推動部142沿方向A’推動推鈕14。隨推鈕14更往母扣11內部移動時,助推條141受母扣11內的斜面115抵觸,其將迫使具有撓性的助推面1412往上推動舌片124。同時,助推條141上的助推面1411亦將抵觸舌片124,進而迫使舌片124往上移動。因此,藉由助推面1411、1412的作用,舌片124的卡合孔125將脫離卡合凸台113的限制。
圖10為繪示解開安全扣具的局部動作圖。如圖10所示,助推面1411亦延伸形成朝向容置孔112的斜面145。故,隨推鈕14往母扣11內部移動時,助推面1411、1412將舌片124往上推動,且斜面145亦將抵觸舌片124的外緣126,藉以將舌片124沿方向B’自母扣11的容置孔112自動推出,同時也帶動兩肩帶扣13彈出。
當外加的推動力被去除後,藉由回位觸條143的彈力使推鈕14回位。如圖8所示,為防止回位觸條143被過度推移而斷裂,母扣11內側也凸設有兩限位肋116。
請參考圖11,推鈕14的背部還設置有兩倒扣144,用於與母扣11背面的兩卡合孔125相扣合,避免推鈕14從母扣11中脫出。
綜上所述,如需解開安全扣具時,藉由推動推鈕14的推動部142,兩助推斜面1411及1412會使得腰帶扣12隨著肩帶扣13一起彈出。若需組裝安全扣具時,先將腰帶扣12與肩帶扣13相卡合,然後直接將相連的腰帶扣12、肩帶扣13***母扣11即可。由於安全扣具的設計將解開時所需的推動力與腰帶扣12、肩帶扣13***或脫開母扣11的方向皆設置於同一平面,故安全扣具不易解開,安全性有保證,且還能有效地保證腰帶扣與肩帶扣之間的卡合。安全扣具釋鎖後卡合也便利。
本發明的安全扣具可適用於任何嬰兒承載裝置上,諸如嬰兒車、安全座椅或高腳椅等。圖12為繪示依本發明一實施例將安全扣具1應用於嬰兒承載裝置20上的示意圖。所示嬰兒承載裝置20例如為嬰兒車,其設有承載體23、肩帶25、腰帶27、支撐腳28及輪子29。各肩帶25的一端與安全扣具1的肩帶扣連接,各腰帶27的一端則與安全扣具1的腰帶扣連接。因此,藉由安全扣具1,可將肩帶25及腰帶27扣合在一起。
以上所述者僅為用以解釋本發明之較佳實施例,並非企圖據以對本發明做任何形式上之限制,是以,凡有在相同之發明精神下所作有關本發明之任何修飾或變更,皆仍應包括在本發明意圖保護之範疇。
