Abstract

This mechanism enables an electronic chassis cabinet which is mounted on slides in an equipment rack to be pulled out of the rack and rotated to a desired angular position to facilitate testing and servicing of the printed circuit cards and components located on the chassis. As shown in the partially disassembled view of Figs. 1 and 2, this mechanism is comprised of a locking plate 10 made from spring steel and having affixed at one end thereof a cylindrical plug element 11 which is designed to engage a selected one of a series of positioning holes 12 formed in the side cover of a chassis cabinet 13. Slide 14 is the slide which is normally used to mount the cabinet 13 to the equipment rack. It is located on a vertically extending rail member 15 which is part of the internal construction of the rack enclosure.

Chassis Cabinet Rotating and Locking Mechanism

This mechanism enables an electronic chassis cabinet which is mounted on slides in an equipment rack to be pulled out of the rack and rotated to a desired angular position to facilitate testing and servicing of the printed circuit cards and components located on the chassis. As shown in the partially disassembled view of Figs. 1 and 2, this mechanism is comprised of a locking plate 10 made from spring steel and having affixed at one end thereof a cylindrical plug element 11 which is designed to engage a selected one of a series of positioning holes 12 formed in the side cover of a chassis cabinet 13. Slide 14 is the slide which is normally used to mount the cabinet 13 to the equipment rack. It is located on a vertically extending rail member 15 which is part of the internal construction of the rack enclosure. Cabinet 13 is pivotally mounted on the slide 14 by means of a pivot screw 16 which passes through holes 17 and 18 and is screwed into a threaded hole 19 in the side of the cabinet 13. A shoulder 20 on the pivot screw 16 is sized to permit rotation of screw 16 in holes 17 and 18. In its locking position, the plug 11 extends through a hole 21 in slide 14 and into a selected one of the positioning holes 12 in the cabinet 11. The partial view of Fig. 2 within the dashline circle shows the locking plate 10 from a different angle to more clearly show the shape and location of the plug 11. When testing or servicing of ...
