    • A folding and lock mechanism for a pushcart includes a bracket pivotally mounted at its proximal end on a rear face of a rear leg intermediate opposite ends of the rear leg so that the bracket can be pivotally moved along the rear face of the rear leg between a generally upstanding position and a lower position. A retainer plate is formed on a lower end of a handle grip, and has a bifurcated end of a generally L-shape or inverted Y-shape defined by a pair of engaging arms. The retainer plate is pivotally connected to the distal end of the bracket at that portion of the retainer plate where the pair of engaging arms merge together. One of the two engaging arms is fitted in a groove formed in the distal end of the bracket to maintain the assembled condition of the pushcart whereas the other engaging arm is fitted in the groove to maintain the folded condition of the pushcart. A tubular stopper is fitted on the distal end portion of the bracket and is slidingly movable along the bracket. The stopper is able to fit on and retain either of the pair of engaging arms which is selectively fitted in the distal end of the bracket.
    • 用于推车的折叠和锁定机构包括:支架,其枢转地安装在其近端处在后腿的相对端部的后腿的后表面上,使得支架能够沿着后腿的后表面在 一般是直立的位置和较低的位置。 保持板形成在把手的下端,并且具有由一对接合臂限定的大致L形或倒置的Y形的分叉端。 保持板在保持板的一部分接合臂合并在一起的位置处枢转地连接到支架的远端。 两个接合臂中的一个装配在形成在支架的远端中的槽中,以保持手推车的组装状态,而另一个接合臂装配在槽中以保持手推车的折叠状态。 管状止动件装配在支架的远端部分上,并且可沿支架滑动。 止动器能够装配并保持选择性地装配在支架的远端中的一对接合臂中的任一个。

    • An auxiliary chair is to be removably mounted on an automotive seat. The chair comprises a seat portion having a front edge and a rear edge, a backrest extending from said rear edge of the seat portion, and an adjuster a slant angle of the seat portion. The adjuster includes a pair of adjusting bars each of which pivotally attached at its proximal end to a lower portion of the seat portion, so that the adjusting bar may take a forward portion and a rearward position. A fixing mechanism includes a pair of engaging levers each of which is pivotally attached at its proximal end portion to a side surface of the seat portion so that its distal end portion may freely be angularly moved. The fixing mechanism further includes associated engagement mechanisms each of which is provided at the side of the seat portion and is engagable with the proximal end portion of the engaging lever.
    • 辅助椅子可拆卸地安装在汽车座椅上。 椅子包括具有前边缘和后边缘的座椅部分,从座椅部分的所述后边缘延伸的靠背和座椅部分的倾斜角度的调节器。 调节器包括一对调节杆,每个调节杆在其近端枢转地附接到座部的下部,使得调节杆可以采取前部和后部位置。 一种固定机构包括一对接合杆,每个接合杆在其近端部分枢转地附接到座部分的侧表面,使得其远端部分可以自由地成角度地移动。 固定机构还包括相关联的接合机构,每个接合机构设置在座椅部分的侧面并且可与接合杆的近端部分接合。
