    Abstract: The present invention is provided with a mechanism for controlling the opening and closing of a door comprising a speed reduction means for reducing a rotational speed. A high speed shaft is connected to the speed reduction means and is connectable to a means for rotating the input shaft, and a low speed output shaft is connected to the speed reduction means. A governor is mounted on the input shaft for limiting the rotational speed thereof, to also regulate the rotational speed of the output shaft. A brake is provided for preventing rotation of the output shaft, and a self-closing mechanism is operatively connected to the door. The self-closing mechanism is adapted for storing energy when the door is opened to an open position, and a connecting means operatively connects the output shaft to the self-closing mechanism. A releasing means is provided for releasing the brake to permit rotation of the output shaft under the urging of the self-closing mechanism whereby the self-closing mechanism releases the energy stored therein so as to close the door to a closed position when the brake is released by the releasing means.

    Abstract translation: 本发明提供一种用于控制门的打开和关闭的机构，其包括用于减小转速的减速装置。 高速轴连接到减速装置，并且可连接到用于旋转输入轴的装置，并且低速输出轴连接到减速装置。 调速器安装在输入轴上以限制其转速，也可调节输出轴的转速。 设置有用于防止输出轴旋转的制动器，并且自动关闭机构可操作地连接到门。 自动关闭机构适于在门打开到打开位置时存储能量，并且连接装置将输出轴操作地连接到自动关闭机构。 提供释放装置以释放制动器以允许在自动关闭机构的推动下输出轴的旋转，由此自动关闭机构释放存储在其中的能量，以便当制动器为制动器时将门关闭到关闭位置 由释放手段释放。

    Abstract: A horizontal sliding door for a housing such as a cabinet. An axle rotatably mounted at the rear of the door projects into two identical tracks one at each side of the housing. Each track has a lower toothed rack and an upper stop surface facing the rack. A pinion slideably and non-rotatably mounted on each end of the axle engages the rack and is held there by an idler wheel slideably and rotatably mounted beside each pinion. A spacer sleeve near one end of the axle is removable, allowing one pinion and idler wheel to be slid inwardly, allowing removal of the door by passing that one end of the axle through a slot in one end of the track.
