    • A drive bay opening in the front bezel portion of a tower type computer CPU unit is provided with a swing-out plastic access door. The door is pivotable between a closed position and a full open stop position in which it is outwardly pivoted more than ninety degrees away from its closed position. A specially designed concealed, break-away hinge structure removably interconnects the access door and front bezel portion and includes a pair of hinge arms projecting outwardly from the door and molded integrally therewith. Outer end tabs in the hinge arms have apertures therein that rotatably receive hinge pins within recessed pocket areas in the bezel. In the event that the access door is forcibly pivoted outwardly beyond its full open stop position, separate disconnect pins disposed laterally outwardly of the hinge pins act as cams that torsionally deflect the hinge tabs out of engagement with the hinge pins. AS a result, the door simply pops off the bezel without damaging either the door, the hinge structure or the bezel. The hinge arm tabs of the separated, undamaged access door may subsequently be snapped back onto the hinge pins with chamfered edge portions of the tabs initially engaging domed portions of the hinge pins to torsionally deflect the tabs in a manner facilitating their reconnection to the hinge pins on the bezel.
    • 塔式计算机CPU单元的前挡板部分中的驱动器托架设置有摆动塑料检修门。 门可在关闭位置和完全打开的停止位置之间枢转,在该位置中,门从关闭位置向外枢转超过九十度。 一种特别设计的隐蔽式断路铰链结构,可拆卸地将检修门和前挡板部分互连,并包括从门向外突出并与其成一体模制的一对铰链臂。 铰链臂中的外端突片在其中具有孔,其可旋转地接收在挡板中的凹进凹槽区域内的铰链销。 在门被强制地向外枢转超过其完全打开的停止位置的情况下,横向向外设置铰链销的单独的断开销作为凸轮,其将铰链突片扭转偏转与铰链销的接合。 因此,门只会弹出挡板,而不会损坏门,铰链结构或挡板。 分离的,未损坏的进入门的铰链臂突片随后可能被卡扣回到铰链销上,其中突片的倒角边缘部分最初接合铰链销的圆顶部分,从而以便于它们重新连接到铰链销的方式扭转突出部 在挡板上。
