Abstract: A tower computer housing has a molded plastic exterior wall portion with an access opening therein, a molded plastic access door, and a specially designed hinge structure that supports the access door on the housing for pivotal movement relative thereto between closed and open positions in which the door respectively covers and uncovers the access opening. The hinge structure includes spaced pairs of hinge pins and cam arms molded integrally on opposite ends of the access door, and spaced apart first and second resilient mounting and spring tab sets molded integrally with the housing exterior wall portion. Each of these sets includes a resilient mounting tab having a mounting hole therein and positioned between an opposed pair of resilient spring tabs. The door pins are removably snap-fitted into the mounting tab holes, and each of the door cam arms is positioned between and slidingly engages a pair of the spring tabs. When the door is manually pivoted through an initial arc toward a selected one of its closed and open positions, the spring tabs are deflected and function to automatically drive the door through a final arc to its selected position.

Abstract: A drive bay opening (24) in the front bezel portion of a tower type computer CPU unit is provided with a swing-out plastic access door (26). The door (26) 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 (28) removably interconnects the access door (26) and front bezel portion and includes a pair of hinge arms (42,44) projecting outwardly from the door (26) and molded integrally therewith. Outer end tabs (62) in the hinge arms (42,44) have apertures (68) therein that rotatably receive hinge pins (46,48) within recessed pocket areas in the bezel (22). In the event that the access door (26) is forcibly pivoted outwardly beyond its full open stop position, separate disconnect pins (54,56) disposed laterally outwardly of the hinge pins (46,48) act as cams that torsionally deflect the hinge tabs (62) out of engagement with the hinge pins (46,48). As a result, the door (26) simply pops off the bezel (22) without damaging either the door (26), the hinge structure (28) or the bezel (22). The hinge arm tabs (62) of the separated, undamaged access door (26) may subsequently be snapped back onto the hinge pins (46,48) with chamfered edge portions (72) of the tabs (62) initially engaging domed portions (74) of the hinge pins (46,48) to torsionally deflect the tabs (62) in a manner facilitating their re-connection to the hinge pins (46,48) on the bezel (22).

Abstract translation: 塔型计算机CPU单元的前挡板部分中的驱动器托架开口（24）设置有摆动塑料检修门（26）。 门（26）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。 一个特别设计的隐蔽的分离式铰链结构（28）可移除地将检修门（26）和前挡板部分互连，并且包括从门（26）向外突出并与其成一体模制的一对铰链臂（42,44）。 铰链臂（42,44）中的外端翼片（62）在其中具有孔（68），其可旋转地接收在所述挡板（22）中的凹进凹槽区域内的铰链销（46,48）。 在进入门（26）被强制地向外枢转超过其完全打开的停止位置的情况下，设置在铰链销（46,48）的横向外侧的单独的断开销（54,56）用作凸轮，其使铰链片 （62）与铰链销（46,48）脱离接合。 结果，门（26）简单地从挡板（22）弹出而不损坏门（26），铰链结构（28）或边框（22）。 分离的，未损坏的检修门（26）的铰链臂突片（62）可以随后被卡扣回到铰链销（46,48）上，突片（62）的倒角边缘部分（72）初始接合圆顶部分 ）以便于它们重新连接到所述边框（22）上的铰链销（46,48）的方式扭转所述突片（62）的转动。
