Door knob construction

A knob construction, comprising

• a knob body having an outer end opening,
• a radially-inward-facing groove in the wall defining such end opening,
• stop means positioned in said opening,
• and an end face member having a skirt pressed against said stop means and thereby deformed outward into said groove to secure the member in the end opening.

A knob construction, comprising

• a knob having a neck portion, an intermediate portion, and an outer end portion, the intermediate and end portions forming a handle by which the knob may be grasped for operation,
• said outer end portion being formed with an end opening sufficient to clear a key-actuated lock core having a cylindrical body containing a key-rotatable plug mounted coaxially of the knob and having a pin-tumbler section extending laterally from the cylindrical body,
• the wall of said end opening being formed with an axially-outward-facing shoulder and a radially-inward-opening groove,
• a locating ring mounted in said opening with its edge opposite a portion of the mouth of said groove,
• and an end face member fitted in said end opening and having a peripheral skirt, the end of such skirt being pressed against the edge portion of the ring and thereby deformed outward into the groove to secure the member in the knob,
• said end member being of a size to contain the end of a lock core as defined.

A cylinder lock, comprising

• a lock chassis having a projecting knob sleeve formed at its end to provide a cage for mounting a key-removable core therein,
• a knob mounted about said sleeve, said knob having a neck portion mounted for rotation coaxially with the knob sleeve and having an outer end portion formed with an end opening larger than the knob sleeve,
• the wall of said end opening being formed with an axially-outward-facing shoulder and an adjacent radially-inward-opening groove,
• a locating ring seated on said shoulder and engaging said knob sleeve to locate the outer end of the knob coaxially with the knob sleeve, the circumferential edge of said ring being disposed opposite said groove to partially close the mouth thereof,
• and an end member fitted in said end opening and having a skirt portion pressed against the edge of said ring and deformed outward thereby into entrapment in the groove to secure itself and the ring axially in place in the knob.

A cylinder lock, comprising

• a lock chassis having a projecting knob sleeve formed at its outer end to provide a cage for mounting a key-removable core therein, said cage being open at its outer end for insertion of the core endwise therein and having an end face for engagement by a face flange on the core to locate the core axially in the cage,
• a knob mounted about said sleeve, said knob having a neck portion mounted for rotation coaxially with the knob sleeve and having an outer end portion formed with an end opening larger than the knob sleeve,
• a locating ring fixed in the outer end portion of the knob and engaging said knob sleeve inward of its said end face to locate the outer end of the knob coaxially with the knob sleeve,
• and an end face member fitted in said end opening and having an opening therein to pass the face flange of the core through the member for engagement with said end face on the knob sleeve, the knob and core being thereby supported by the knob sleeve independently of each other.

A cylinder lock, comprising

• a knob mounted about said sleeve, said knob having a neck portion mounted for rotation coaxially with the knob sleeve and having an outer end portion formed with an end opening larger than the knob sleeve,
• means in said end opening for forming an end face on the knob and for engaging the knob sleeve rearward of the end face of such sleeve to locate the outer end of the knob coaxial with the knob sleeve,
• said means having an opening therein to expose said end face for engagement by a core face flange and to pass a core into the cage and pass its face flange into engagement with said end face, the knob and core being thereby supported by the knob sleeve independently of each other.
