Abstract

A technique is described whereby a bridge assembly provides a support frame for mounting electromagnetic devices, such as fixed disk or floppy disk drive units. The bridge assembly is unique in that the drive units are bridged over a planar circuit board in such a way so as to allow simplified installation and removal of the planar board. The bridge assembly also provides an "inward bowing" feature which exerts retaining forces onto the drive units, thereby eliminating the need for retaining screws. The bowing feature also acts as a shock mount to the electromagnetic device when installed. The bridge assembly, as shown in the drawing, consists of a pair of die cast mounting bars, left bar 10 and right bar 11, which contain lower tabs 12 and 13 so that bars 10 and 11 may be fastened to framework 14 by means of screws.

Bridge Assembly for Mounting Interchangeable Electromagnetic Devices

A technique is described whereby a bridge assembly provides a support frame for mounting electromagnetic devices, such as fixed disk or floppy disk drive units. The bridge assembly is unique in that the drive units are bridged over a planar circuit board in such a way so as to allow simplified installation and removal of the planar board. The bridge assembly also provides an "inward bowing" feature which exerts retaining forces onto the drive units, thereby eliminating the need for retaining screws. The bowing feature also acts as a shock mount to the electromagnetic device when installed. The bridge assembly, as shown in the drawing, consists of a pair of die cast mounting bars, left bar 10 and right bar 11, which contain lower tabs 12 and 13 so that bars 10 and 11 may be fastened to framework 14 by means of screws. The rear portion of bars 10 and 11 extend through slots 15 and 16 of framework 14. Electromechanical device 17 has a pair of side rails 18 which are used for mounting into the bridge assembly at upper slots 19 and 20 or lower slots 21 and 22. This provides for the mounting of two device units into each bridge assembly. Each of the mounting bars 10 and 11 are bowed inward toward their center portions so as to provide a clamping force onto device 17 when installed. This "inward bowing" feature eliminates the need for screws to secure device 17 to bars 10 and 11. The rear portion of bar 10 contains a pair of L-shaped s...
