Description

儿童汽车椅
技术领域
本发明一般而言是与一儿童汽车椅有关，特别是涉及一种可直觉性地轻松操作的儿童汽车椅座位角度调整装置。
背景技术
以往在儿童汽车椅市场上虽然有许多不同的倾斜调整装置设计，但许多习知调整装置不易操作，特别是无法令使用者直觉判断调整操作部位并流畅地完成倾斜度调整，因此调整装置在使用上的便利性仍有改进空间。举例而言，参见图1、2，2006年1月13日颁给Eugene RoyBalensiefer等人的美国专利第7,059,677号揭露一种儿童汽车椅倾斜调整装置，其中倾斜式底座100包括一座位构件140、一底座160，以及一可松解的锁定装置300，该锁定装置300包括一安装在底座160上的固定件320，一安装在座位构件140上且可移动于一锁定位置与一释锁位置之间的调整钮340，以及一配置成可偏压调整钮340使其与固定件的固定杆320对接而将座位构件140相对底座160维持一选择倾斜位置的弹簧360。要改变倾斜夹角时，使用者可依图1中的箭头方向P拉动调整钮340的手柄620，此时弹簧360被压缩使得调整钮340的固定臂810与固定件320分离，容使座位构件140相对支持底座160绕一后端枢转轴200自由转动以改变倾斜位置，并借由使固定件320与固定臂810上的一凹槽嵌合而将座位构件140维持选择的倾斜度，如图2所示。此一前案中使用者必需先解除座位构件140与底座160之间的夹角位置锁定，然后再转动调整座位构件140的倾斜度，因此调整上为不连续操作且通常还需要另外施力来协助调整座位的角度，因此较为不便。
发明内容
本发明的主要目的是提供一种借单手扳动操作手柄即可完成座位构件与底座间的倾斜夹角调整的儿童汽车椅。
本发明的另一目的是提供一种使用者可直觉性地调整座位构件倾斜度的儿童汽车椅。
本发明的再一目的是提供一种在调整座位构件倾斜夹角时，具有弹性辅助能力的儿童汽车椅。
本发明的又一目的是提供一种倾斜度调整部位露出于汽车椅前方，使用者能立即判断应操作部位的儿童汽车椅。
本发明的更进一步特征是提供一操作流畅且省力的儿童汽车椅倾斜度调整装置。
本发明的儿童汽车椅包含一座位构件与一枢接在座位构件下方的底座构件，座位构件与底座构件之间借由一锁定装置维持一相对夹角，锁定装置具有：一设置在底座构件上的第一锁定件，可提供复数预定高度的锁定位置；一枢接在座位构件前端的锁定块，锁定块包括一第二锁定件，该第二锁定件可与第一锁定件在一选择之预定高度位置锁定，并可通过锁定块朝座位构件外侧枢转而解除锁定；以及一拉伸弹簧，其两端分别与所述锁定块及底座构件连接，当第二锁定件与该第一锁定件解除锁定时，拉伸弹簧作用在底座构件上的拉力使底座构件产生一向下转矩。
依据本发明的上述儿童汽车椅中，底座构件上设有一对横向间隔的托架，枢接在座位构件上的锁定块可相对托架枢转，托架前端面设置有复数不同高度之卡槽，锁定块的两侧分别具有固定杆且能与该托架上一选择高度之卡槽嵌接。
本发明的儿童汽车椅中，底座构件的后端枢接至座位构件的中段位置，当座位构件与底座构件之夹角为0°时，拉伸弹簧与底座构件的枢接点水平高度比与锁定块的枢接点水平高度为高。

图9是本发明的汽车椅实施例当座位构件已相对底座构件调整为一倾斜夹角时的局部侧剖视示意图。
具体实施方式
参见图3、4，其中示出一结合本发明倾斜调整装置的儿童汽车椅1。此一汽车椅1的实施例如同图3中所示出的为一高背型儿童汽车椅。由于座位本体10与本发明的特征无关且可采取不同实施方式，故在部分图式中予以省略。参见图4，座位构件20是由两半壳体21，22所组成，底座构件30是由一底板31与一组接在底板31上方的座壳32所组成，座位构件20的下壳体22于前后方向的中间位置设有两枢接孔220，且底座构件30的座壳32两侧于后端分别设有枢接柱320，座位构件20与底座构件30可借枢接孔220与枢接柱320形成一枢转支点50而将底座构件30枢接在座位构件20的下方，且座位本体10的前端被底座构件30支撑，而后端被座位构件20支撑。如此，安装在座位构件20上的座位本体10连同乘坐在座位本体10上的幼儿重量是由底座构件30与座位构件20共同支撑。
如图4中所示，一锁定块40枢装在座位构件20下且介于底座构件30的底壳32与座位构件20的壳体22之间，锁定块40具有一操作手柄401，壳体构造402及分别延伸于壳体构造402两侧的延伸壁403，该锁定块40可安装于座位构件20之下半壳体22前方一缺槽221中，并可容使锁定块40前端的操作手柄401凸出于座位构件20的壳体前缘，此一操作手柄401为一底部敞开的壳体，使用者可将手指伸入壳体并借由扳转操作手柄401使锁定块40枢转。由图3中可见，操作手柄401和汽车椅底座构件30皆可由汽车椅1正面被看见，因此使用者可立即判断调整时应操作的部位。
锁定块40安装于缺槽221的方式，是以壳体构造402枢接在座位构件20的下半壳体22下方，且能朝向座位构件20前方枢转，请参见图4与图7，此一壳体构造402包含一斜壁406及两侧壁407，该斜壁406的两侧缘分别与两侧壁的顶缘连接，而斜壁及两侧壁的前缘分别与操作手柄401连接，两侧壁的后端边缘分别横向延伸出一延伸壁403，如此壳体构造402及延伸壁403可与操作手柄401连动。另外，延伸壁上端缘分别藉由枢杆(图式中未标示)5与座位构件20枢接，使锁定块40可相对于座椅构件20枢转。延伸壁403下方端缘处有一固定杆404，图7中，壳体构造402的两侧延伸壁403下端缘之间具有一与二固定杆404同轴的杆体或具有一连接于壳体构造402且与二固定杆404水平高度相同的连接点(图式中未标示)，该杆体(或连接点)与底座构件30之间连接一拉伸弹簧60，拉伸弹簧60一端固定在该杆体(或连接点)的横向中间位置，另一端连接至底座构件30的一固定座310上，且连接于固定座310上位置的高度高于与锁定块40的连接位置高度。
如图6所示，若汽车椅1所放置的支撑面为一平面，底板31与支撑面的接触面311会与座椅构件20与支撑面的接触面222成一平行的状态，拉伸弹簧60在锁定块40与固定座310之间形成与底板31倾斜的状态，拉伸弹簧60与固定座310之垂直方向形成一锐角。
请再参阅图4及图5，底座构件30的座壳32内部具有一对相间隔的托架324，托架324朝向座位构件20前方的前端面形成数个不同高度位置的卡槽325，卡槽具有圆弧形截面，其剖面轮廓在图6中看得比较清楚，本实施例中托架324有三个卡槽325，当固定杆404嵌合最下方卡槽325中时，座位构件20的接触面222会平行于底座构件30的接触面311，如图6中所示。当固定杆404分别嵌合于较上方的二卡槽325中时，座位构件20的接触面222会与底座构件30的接触面311之间形成一夹角，如图9所示。藉由前述两不同部位的接触面311，222，将汽车椅1与汽车椅所承载的重量传递到一支撑面之上。
参见图7至图9，使用者若要将图7中汽车椅1的座位本体10由直立状态调整为图9的倾斜状态，如图8所示，可将操作手柄401向座位构件20外侧扳转，此时锁定块40上的固定杆404脱离托架324的最下方卡槽325，由于拉伸弹簧60与托架324的枢接点最初是在拉伸弹簧60与锁定块40的枢接点上方，所以当拉伸弹簧60受外力拉伸时，藉拉伸弹簧60传递而作用在底座构件30固定座310上的外力，会有一垂直(向下)分力及水平分力，此一向下分力使底座构件30受到一相对于枢转支点50的转矩作用而向下抵接于汽车椅1所置放的支撑面，因此只需向上调整座位构件20与底座构件30的夹角即可完成座位本体10的倾斜角度调整，且由于施力在操作手柄401的方向与座位构件20的调整方向同向，所以可让操作更为容易。如图9所示，由于托架324与锁定块40的相对位移，使得固定杆404自动地对应一较上方卡槽325，因此使用者能够顺势调整座位构件20的倾斜度，在座位构件20的倾斜度调整上十分轻松省力。
随着前述座位构件20倾斜夹角的调整，拉伸弹簧60连接在锁定块40的一端相对与另一端的高度差减小，拉伸弹簧60与固定座310的高度方向间的角度逐渐加大接近90°，因此，前述对底座构件20的向下分力随角度改变也渐减，使得底座构件30减缓向下转动，此外，在外力移除后，拉伸弹簧60的复位弹性使锁定块40具有一朝向托架324的偏压，因此使用者十分容易顺势使固定杆404再度与卡槽325嵌合。
当使用者要将图9中所示汽车椅1的倾斜椅背状态再度调整成图7所示的直立椅背状态时，首先扳动操作手柄401以使固定杆404与卡槽325脱离嵌合，座位构件20的前端将因自身的重量下降而使其与底座构件30之间的夹角减少至0°，此一过程中，拉伸弹簧60连接在锁定块40的一端相对于另一端的高度差加大，作用在底座构件30上的拉力的向下分力使底座构件30受到一向下转矩，使底座构件30的接触面311紧贴于汽车椅1所在的支撑面上，所以使用者仅需施力于座位构件20的夹角调整动作之上，无须同时注意座位构件20与底座构件30的相对关系，使角度调整的操作较为简单。
随着座位构件20的前端下降，锁定块40将与托架324产生相对位移，使固定杆404移向最下方卡槽325的位置，松开操作手柄401后即可使固定杆404与该最下方卡槽325嵌合，将椅背锁定于直立状态。
本发明中的底座构件30与锁定块40都为塑胶射出成型制件，上述实施例中是以拉伸弹簧60来作说明，但也可考虑使用可达成相同目的的其他长形弹性元件，例如弹片。
应理解本说明书中所描述及示出用来解释本发明特征性质的构造及元件配置可有所变化，且本领域技术人员了解本说明书的内容后，可在本发明的原则与范围内完成该等变化。
