  • Removable electrical unit with combined grip and release mechanism exposed by partial withdrawal
    Patent number: 5309323
    Abstract: A removable electrical unit 20 is described which incorporates a soft stop and releasing mechanism which is employed to prevent removal of the unit from its housing in an unsafe manner. In operation, the unit is pulled from the housing by means of a front handle 22 on the unit and when the unit is partially removed from its housing a stop block 72 on the unit engages a stop spring 90 on the housing. A second handle 30 on the top of the unit becomes accessible and is actuated to disengage the stop block and stop spring. The unit may then be completely removed from the housing in a safe two handed manner.
