Abstract
The latch assembly is provided with a locking collar and a pair of knockouts so that the latch assembly can be easily converted to a latch-lock assembly by simply inserting a cylinder lock in the proper knockout, depending upon whether the assembly is used in a right-hand or left-hand installation. The conversion of the assembly may be made before or after installation of the latch-lock assembly.
Claims5
A latch assembly adaptable for use with a panel mounted for either right-hand or left-hand swinging movement in a mating frame and between open and closed positions, said latch assembly being easily convertible to a latch-lock assembly and comprising
- a. a pan-shaped housing including a peripheral rim mounted on and surrounding an opening in said panel, and a depressed central surface positioned in the opening in said panel,
- b. a latch-operating stem supported for rotation in said depressed central surface of said pan-shaped housing and including an outer end portion extending through said depressed central surface of said housing, and an inner end portion extending inwardly from said depressed central surface,
- c. an operating handle secured to said outer end portion of said latch-operating stem, said handle being manually operable to rotate said latch-operating stem,
- d. a latching pawl including an inner end fixed on a medial portion of said latch-operating stem and a free outer end extending outwardly therefrom, said latching pawl being movable with rotation of said latch-operating stem between a latched position with said free outer end in engagement with said mating frame and an unlatched position with said free outer end out of engagement with said mating frame,
- e. a locking collar fixed on said latch-operating stem and adjacent the inside of said depressed central surface, and
- f. a knockout formed in said depressed central surface of said pan-shaped housing and positioned on each side of said latch-operating stem, said knockouts being shaped to selectively receive a key-operated locking cylinder which is engageable with said locking collar to convert the latch assembly to a latch-lock assembly.

- e. a locking collar fixed on said latch-operating stem and adjacent the inside of said depressed central surface,
- f. a knockout formed in said depressed central surface of said pan-shaped housing and positioned on each side of said latch-operating stem, said knockouts being shaped to selectively receive a key-operated locking cylinder, one of said knockouts being removed, and
- g. a key-operated locking cylinder positioned in said one knockout opening, said key-operated locking cylinder being movable into and out of engagement with said locking collar for locking and unlocking said latch-lock assembly.
