Abstract

This latching mechanism is particularly for the purpose of securing an electronic package within a rack. Positive movement into and out of a final resting position for the package is afforded by the mechanism. A frame member 10 is fixed to the rack, which member has a stop 11 projecting downwardly. The latching mechanism is mounted on the package 12, which is to be inserted into the rack. The latching arm 13 is provided with a collar 14 pivotally mounted on an eccentric 15, which is pivotally mounted on a pin 16 secured to the package 12. A handle 17 is integral with eccentric 15, there being a frictional washer (not shown) between the handle and collar 14.

Latching Mechanism

This latching mechanism is particularly for the purpose of securing an electronic package within a rack. Positive movement into and out of a final resting position for the package is afforded by the mechanism. A frame member 10 is fixed to the rack, which member has a stop 11 projecting downwardly. The latching mechanism is mounted on the package 12, which is to be inserted into the rack. The latching arm 13 is provided with a collar 14 pivotally mounted on an eccentric 15, which is pivotally mounted on a pin 16 secured to the package
12. A handle 17 is integral with eccentric 15, there being a frictional washer (not shown) between the handle and collar 14. As the handle 17 is moved outwardly and forwardly, eccentric 15 pivots about pin 16 and urges arm 13 horizontally and to the right until the end of the arm is disengaged from stop 11. Continued movement of the handle causes the arm 13 to be rotated downwardly until it engages a pin 18. Thereafter, the tooth 19 on eccentric 15 goes into a detent 20 in pawl 21, which is pivotally mounted at 22 on arm 13. Now the surface 23 of the handle engages the surface 24 on rack 10 and urges the package from the rack sufficiently to disengage the electrical connecting pins (not shown) between the rack and package.

To replace the package, it is inserted in the rack and the handle is rotated downwardly until the free end of pawl 21 engages stop 11. Unless this occurs, it is known that the package is not suf...
