    Abstract: A slidable door assembly for opening and closing an opening or entranceway including a hanger plate having hanger and up-thrust rollers thereon, a door panel fixed to the hanger plate, and a support structure disposed above the door opening. The support structure includes a hanger track upon which the hanger rollers travel, and a horizontally oriented guide or bearing surface which co-acts with the up-thrust rollers. A door stabilizer is fixed to the door panel, adjacent to its trailing edge, with reference to its closing movement, which includes a roller whose rotational axis is disposed outside the vertical projection of the door panel. The roller of the door stabilizer co-acts with a guide surface, which may be the same guide surface used by the up-thrust rollers, to protect the up-thrust rollers from excessive force, and prevent untracking of the hanger rollers, when a force is applied to the leading edge of the door panel.

    Abstract translation: 一种用于打开和关闭开口或入口的可滑动门组件，包括其上具有衣架和上推辊的衣架板，固定到衣架板的门板和设置在门开口上方的支撑结构。 支撑结构包括衣架滚轮行进的悬挂架轨道，以及与上推滚轮共同作用的水平定向的导向或支承表面。 相对于其关闭运动，门稳定器固定到门板的与其后缘相邻的位置，该闭合运动包括其旋转轴线设置在门板的垂直突起外侧的辊。 门稳定器的滚子与引导表面共同作用，该引导表面可以是与推进滚子一起使用的相同的引导表面，以保护上推滚筒免受过大的力，并且防止吊架滚筒的开启，当 力被施加到门板的前缘。

    Abstract: A self-closing door hinge is characterized as that the door can be automatically closed after opening the door and released by hand without any other power aid. Said self-closing door hinge comprises: A main hinge and two auxiliary hinges. Said main hinge is composed of: a right hinge leaf with sleeve, and a left hinge leaf with pivot. Said pivot of left leaf is provided with extended pin rollers which engage with the grooves in said sleeve of the right leaf.Said grooves are made horizontally from 0 degree through 50 degrees based on the zero degree line as door closing and then inclined upwards from 50.degree. through 180.degree.. Whenever opening the door, the pivot of the left hinge leaf fixed on the door will be rotated so that the pin rollers thereof may be slipped along the grooves so as to raise the left hinge leaf and door upwards against the right hinge leaf which is fixed on the door frame. The raised door having potential will automatically fall by the gravitational force so as to close the door itself.

    Abstract translation: 自动关门门铰链的特征在于，门可以在打开门之后自动关闭，并在没有任何其他助力的情况下用手释放。 所述自动关闭门铰链包括：主铰链和两个辅助铰链。 所述主铰链由：具有套筒的右铰链叶片和具有枢轴的左铰链叶片组成。 左叶的所述枢轴设置有延伸的针辊，其与右叶的所述套筒中的凹槽接合。 所述槽基于作为门关闭的零度线从0度至50度水平制成，然后从50度向上倾斜180度。 每当打开门时，固定在门上的左铰链叶片的枢轴将被旋转，使得它们的销辊可以沿着凹槽滑动，以便将左铰链叶和门向上靠在固定的右铰链叶上 在门框上 具有潜力的升高的门将自动地由重力下降，以便关闭门本身。
