ABSTRACT:
A rotational housing assembly for a lock assembly includes a rotational housing, a spindle, and a core retainer. The rotational housing has a sleeve which is adapted to receive a core and defines an inner periphery. A driver is formed in and extends along a longitudinal direction of the inner periphery. The spindle is received in the sleeve to rotate with the rotational housing. The spindle includes a first end adapted to operate a door latch and a second end. A cutout is formed in the second end of the spindle and extends along a longitudinal direction of the spindle and defines a recess in one edge thereof. A driver slot engages with the driver in the sleeve to retain the spindle in the rotational housing. The core retainer is received in the sleeve to engage with the second end of the spindle and has first and second ends. A stop is formed at the second end of .the core retainer and engages with the recess in the spindle. A flange is formed at the first end of the core retainer and a cutout is formed in the flange for engaging with the driver to prevent rotational movement of the core retainer in the sleeve. The stop of the core retainer prevents from longitudinal movement of the core when a core catch in the core is in an extended position. The core is removable when the core catch is in a retracted position.
