Description

折叠桌
本发明涉及折叠桌。
各种各样的折叠桌已广为人知，然而仍有必要提供一种简单但构思巧妙、易竖立易折叠的多用途折叠桌。
按照本发明，一折叠桌，它包含有：一合成塑料桌顶，桌顶有一上工作表面和一下底面；所述下底面具有一对位于其后部的沿横向间隔开的整体式支腿止动器和一对位于其前部的沿横向间隔开的整体式支撑止动器；一包含有一细长连接件和一对从连接件两相对端延伸的支腿的支腿组件，每条支腿各有一从远离连接件的支腿底端处延伸的脚撑件；和一可转动的支撑，它的后端部至少与一支腿呈枢轴连接并以其前端与支撑止动器呈可解脱的啮合；每一整体式支腿止动器具有一付横向放置间距很小且大致相同的整体式支腿止动件，每一支腿止动件以卡持啮合方式夹持住连接件，和每一整体式支撑止动器具有一付横向放置间距很小且大致相同的整体式支撑止动件，每一支撑止动件以可解脱的啮合方式接纳支撑；所述支撑可在一与支撑止动器呈可解脱啮合的工作位置与一从支撑止动器上脱开时位于两支腿之间的收回位置之间转动，支撑与支撑止动器啮合时桌顶保持在一工作位置；每一支腿止动器以可解脱开的卡持啮合方式夹持住连接件，同时允许桌顶在一工作位置与一使桌顶大致与支腿平行的折叠位置之间转动。
每个支撑止动器以可解脱的卡持啮合方式接纳支撑。
每个支撑止动器能在沿前后方向相互间隔开的一组位置处以可解脱的卡持啮合方式接纳支撑。
支撑包含有一对具横向间距的侧支撑件，每一侧支撑件在其后端与一对应的支腿呈枢轴连接，而一根横向支撑件在两侧支撑件的前端之间延伸，被每一支撑止动器接纳的所述横向支撑件在工作位置与支撑止动器间呈可解脱的啮合。
上述每条支腿具有呈伸缩啮合的上部和下部，支腿下部相对于支腿上部在不同的纵向位置处固定以实现对支腿长度的调节。
支腿下部可沿支腿的纵轴线相对于支腿上部转动，支腿下部固定于工作位置上时，脚撑件相互平行，而处于折叠位置时脚撑件则沿相对的方向并排地伸展。
作为例子，现对本发明的一个实施例参照附图进行描述，其中：
图1是一按本发明折叠桌的实例的透视图，桌顶处于水平工作位置；
图2是图1中箭头2所指的桌脚部分的详图；
图3是桌子的一透视图，此时桌顶处于一倾斜的工作位置，图中也示出了桌顶下底面的情况；
图4是桌子处于折叠位置时的透视图；
图5是图3中沿5-5线剖取的桌顶后部的剖视图，图中示出了一支腿止动器和支腿组件的一部分；和
图6是图3中沿6-6线剖取的桌顶前部的一个与图5类似的剖视图，图中示出了一支撑止动器和支撑的一部分。
参阅附图，一折叠桌10有一整体模塑的塑料桌顶12，其形状呈带圆角的矩形平板，桌顶12具有一上工作表面14和一下底面16，下底面16有一对位于其后部并沿其横向相互间隔开的整体支腿止动器18，和一对位于其前部且相互沿横向间隔开的整体支撑止动器20。一钢管制成的支腿组件22包括一横向连接件23和一对从连接件23的相对两端处延伸的支腿24，26，每条支腿24，26各有一细长形的脚撑件28，30，它们分别从24，26的底端延伸。
每个支腿止动器18包括有一付间距很小的相同的支腿止动件32，每个止动件32有钩形部34用来以可解脱的卡持啮合方式来夹持住连接件23，并允许桌顶12可相对于支腿组件22转动，其工作方式将在下文作详述。
每条支腿24，26各自有呈可伸缩啮合的上部36和下部38，支腿下部38可在支腿上部36的外表面上滑动，每一支腿上部36各自与连接件23的对应端构成一体，每一支腿下部38各自与相对应的脚撑件28，30构成一体，因此脚撑件28，30也是由钢管构成。每一支腿下部38有一组分布于其横向外侧和内侧并沿垂直方向有间隔的孔40，每一支腿上部36具有一U形弹性掣卡42，它位于支腿上部的下端如图2所示。掣卡42有一对凸钮44，它们分别在支腿上部36的相对侧穿过孔46并可选择地与支腿下部38上两排孔40中的一对孔呈卡持啮合，这样就可调节支腿24，26的长度，如图1中点划线所示。
为实现将在下文中详述的折叠目的，支腿下部38可绕其纵轴线转动至横向向内的延伸位置，如图3中点划线所示。每一支腿下部38在其前表面上也有一孔48，所以凸钮44中的一个可卡入孔48内以使支腿下部38在朝内折叠位置上被止动住。
一可转动的支撑50可在后部转动地连接于支腿上部36上。支撑50由一金属杆弯曲成形，在前部形成一横向支撑件51，从横向件的两相对端有一对向后延伸、且横向间距的侧支撑件52，每一侧支撑件52在其后部各有一弯曲形自由端部54，54分别伸入对应的支腿上部36的孔56中以使支撑50转动地连接在支腿上部。每个支撑止动器20具有一付间距很小且形状尺寸相同的支撑止动件58，每一支撑止动件58有一组沿前后方向间隔分布的钩形部60，每个钩形部60都可与横向支撑件51呈可解脱的卡持啮合。
图1示出的桌子处在完全竖立的位置，此时桌顶12呈水平，可以理解，为使桌顶12被支撑处于水平位置，横向支撑件51是被夹持在距桌顶12前端最远支撑止动件的钩形部60内。脚支撑件28，30从桌顶12下方的支腿24，26向前方伸展。若希望使桌顶12置于如图1中点划线所示那样的倾斜位置时，横向支撑件51被支持在距桌顶12前端较近的钩形部60内。
桌子可如图4所示那样完全折叠起来，即：可如前述向内旋转脚撑件28，30并从止动钩形部60上使横向支撑件51解脱从而允许支撑50向下转动至接近垂直位置，于是桌顶12就可同样向下转动至接近垂直的位置。
脚撑件28，30可维持在如图1和图3中所示的朝前伸展的位置，支撑50和桌顶12置于接近垂直位置，这样脚撑件28，30可滑动地推入一椅子或长沙发侧方或后方，桌顶12则贴近于椅子或长沙发的侧面或背面，这样今后使用桌子时可方便地取出，这仅需要把桌子滑动推出并用支撑50使桌顶12置于所需的位置上。
通过以上对一最佳实例的描述就可清楚地理解：本发明所提供的一种折叠桌，结构简单但构思巧妙，能很容易地竖立并折叠。
与本发明有关的各种实例对于从事本行业的专业人员说是显而易见的，本发明涉及的范围在所附的权利要求中明确。
