Abstract
A locking system includes a lockcase which can be embedded within a recess in a jamb of a doorway. A barn door mounted outside of the doorway can be locked in the closed position by actuation of a lock mechanism within the lockcase. The handle interacts with the lockcase, causing a bolt to be translated out of the lockcase and into a strike in the barn door. The strike preferably passes entirely through the barn door, the strike including an outer entry which can be accessed via a key to push back the bolt and defeat the lock for emergency access. Cover plates and handles of different types can be provided for optimal performance. Lock mechanisms within the lockcase convert handle actuation into bolt translation between a collapsed orientation and a deployed orientation for locking the barn door.
Claims19
A lock for a barn door, the lock comprising in combination:
- a lockcase slidably supporting an elongate bolt in both a retracted position and a deployed position for said bolt, said lockcase attachable to a jamb of a doorway opening;
- a handle coupled to said lockcase and translating said bolt between said retracted position and said deployed position upon handle motion;
- wherein said handle is rotatably supported relative to said lockcase, with said lockcase converting handle rotation into bolt translation;
- and
- wherein said handle includes an outer hub extending away from said lockcase and with an elongated lever extending from said hub in a direction lateral to a line between said hub and said lockcase, said lever providing a user engageable portion to cause said hub of said handle to rotate and to cause bolt translation relative to said lockcase.

A lock for a barn door, the lock comprising in combination:
- a lockcase slidably supporting an elongate bolt in both a retracted position and a deployed position for said bolt, said lockcase attachable to a jamb of a doorway opening;
- a handle coupled to said lockcase and translating said bolt between said retracted position and said deployed position upon handle motion;
- wherein said handle is rotatably supported relative to said lockcase, with said lockcase converting handle rotation into bolt translation;
- wherein said handle includes a shaft extending into said lockcase, said shaft coupled to a user engaging portion of said handle, said shaft rotating when said user engaging portion is rotated;
- and
- wherein said shaft is faceted on at least portions thereof, with facets of said shaft engaging with said lockcase to cause at least portions of said lockcase to be engaged by said facets and move when said shaft of said handle is rotated.

A lock for a barn door, the lock comprising in combination:
- a lockcase slidably supporting an elongate bolt in both a retracted position and a deployed position for said bolt, said lockcase attachable to a jamb of a doorway opening;
- a handle coupled to said lockcase and translating said bolt between said retracted position and said deployed position upon handle motion;
- wherein a strike defining a recess into which said bolt enters when said bolt is in said deployed position, said strike locatable in the barn door adjacent to the jamb of the doorway opening when the barn door is closed;
- and
- wherein said strike is sufficiently long to extend through the barn door to which it is to be located, said strike having an outer entry on a side of said strike most distant from said lockcase, said bolt translatable from said deployed position to said retracted position by axial linear force upon a distal tip of said bolt through said outer entry of said strike.

A doorway with barn door and privacy lock system, the system comprising in combination:
- a doorway in a wall, said doorway located between a pair of jambs, said jambs including faces which face each other across said doorway;
- a barn door slidably supported adjacent to said wall, with said barn door having a closed position at least partially blocking said doorway and an open position leaving said doorway less blocked than said closed position;
- a lockcase slidably supporting an elongate bolt in both a retracted position and a deployed position, said lockcase attached to one of said jambs of said doorway;
- a handle coupled to said lockcase and translating said bolt between said retracted position and said deployed position upon handle motion;
- a strike defined by a recess in said barn door into which said bolt enters when said bolt is moved into said deployed position, said strike located in said barn door adjacent to said jamb of the doorway when said barn door is in said closed position;
- and
- wherein said strike is sufficiently long to extend through the barn door to which it is to be located, said strike having an outer entry on a side of said strike most distant from said lockcase, said bolt translatable from said deployed position to said retracted position by axial linear force upon a distal tip of said bolt through said outer entry of said strike.
