Cover Retaining Latch

This article describes a terminal cover latch which is spring loaded by molded springs integral with the terminal base member. The latch is assembled and used without auxiliary fasteners or tools.

The only part of the latch which is not integral with either a machine base or a machine cover is a sheet metal member 10 having a pair of fastener catches 12 and 14. The member 10 includes a loading slot 16 and a slide slot 18 at one end. A trigger 20 extends downwardly at this end. A similar loading slot 22 and slide slot 24 are formed near the opposite end of the member 10. A stop arm 26 is formed at the end of the member 10.

A machine base 27 in which the member lO is mounted includes L-shaped retaining guides 28 and 30, a trip spring 32, a tapered beam spring 34 and a load spring 36.

The member 10 is loaded by dropping it into the base 27, with loading slots 16 and 22 aligned with retaining guides 30 and 28, respectively. During the downward travel, the stop arm 26 will contact the upper end of trip spring 32. When the member 10 has been pushed down far enough to align the retaining guides 3O and 28 with the slide slots 18 and 24, respectively, the member 10 can be moved to the left against the forces exerted by the tapered beam spring
34. When the stop arm 26 clears the trip spring 32, the depressed spring will return to its normal position in which it provides a stop limiting the righthand movement of member 10. Member 10 is contacted at one...
