Abstract
A lockcase is mountable upon a surface of a doorway jamb which is selectively closable by a barn door. The lockcase includes a bolt which translates or otherwise moves relative to the lockcase to selectively engage a strike in the barn door. The bolt is actuated by movement of a handle on a lever mounted to the lockcase. In one embodiment, the lever rotates to cause a shuttle to translate and with the bolt mounted to the shuttle. Detents on the shuttle tend to keep the bolt in either a retracted or a deployed position relative to the lockcase and the strike.
Claims20
1:
- A barn door lock, comprising in combination:
- a lockcase movably supporting a bolt in both a retracted position and a deployed position for said bolt;
- said lockcase including at least one fastener for fixing said lockcase to a jamb of a doorway that is selectively closable at least partially by a darn door sliding relative to the doorway;
- a strike in the barn door, the strike receiving said bolt therein when said bolt is in said deployed position;
- and
- a handle coupled to said lockcase, said handle movable to move said bolt between said retracted position and said deployed position.
3 more elements
2:
- The lock of claim 1 wherein said handle is coupled to a lever, said lever pivotable relative to said lockcase.
3:
- The lock of claim 2 wherein said bolt is coupled to said lever, at least indirectly, and translates when said lever pivots.
4:
- The lock of claim 3 wherein a shuttle is located between said bolt and said lever, said shuttle sliding within said lockcase when said lever rotates.
5:
- The lock of claim 4 wherein said lever includes a wheel rotating on a hub and with an arm extending from said wheel, said handle located on said arm of said lever, said wheel including at least one slot therein, said slot engaging a post on said shuttle to translate said shuttle when said wheel rotates in response to forces applied to said arm through said handle.
6:
- The lock of claim 5 wherein a detent on said shuttle resides in one of two troughs formed in a cover of said lockcase when said bolt is in said retracted position and in said deployed position, such that said bolt tends to maintain residence within either said retracted position or said deployed position, unless sufficient forces are applied to dislodge said detent from one of said troughs.
7:
- The lock of claim 1 wherein said at least one fastener includes a plurality of jamb screws extending through portions of said lockcase and into the jamb of the doorway.
8:
- The lock of claim 7 wherein said lockcase includes a base plate, said base plate including said holes for said jamb screws therein.
9:
- The lockcase of claim 1 wherein said strike is located closer to a leading edge of the barn door then to a trailing edge of the barn door.
10:
- The lockcase of claim 1 wherein said strike is located closer to a trailing edge of the barn door and to a leading edge of the barn door.
11:
- The lockcase of claim 1 wherein said strike is a hole in the barn door sized large enough for said bolt to pass into and out of said hole in the barn door.
12:
- The lockcase of claim 1 wherein said strike includes a housing extending through the barn door, with a hole in said housing on a side of the barn door opposite the doorway, the hole sized to receive a key therein to push back said bolt to unlock the barn door.
13:
- A surface mountable barn door privacy lock, comprising in combination:
- a lockcase mountable to a jamb of a doorway selectively closable by a barn door;
- a bolt movably supported by said lockcase in both a retracted position and a deployed position, said deployed position extending further toward the barn door than said retracted position;
- a handle movably supported by the lockcase;
- and
- said handle coupled at least indirectly to said bolt, to move said bolt between said retracted position and said deployed position when said handle moves.
3 more elements
14:
- The privacy lock of claim 13 wherein a strike is located in the barn door, the strike receiving said bolt therein when said bolt is in said deployed position.
15:
- The privacy lock of claim 14 wherein said strike is a hole in the barn door sized large enough for said bolt to pass into and out of said hole in the barn door.
16:
- The privacy lock of claim 14 wherein said strike includes a housing extending through the barn door, with a hole in said housing on a side of the barn door opposite the doorway, the hole sized to receive a key therein to push back said bolt to unlock the barn door.
17:
- The privacy lock of claim 14 wherein a handle is coupled to said lever, said lever pivotable relative to said lockcase;
- wherein said bolt is coupled to said lever, at least indirectly, and translates when said lever pivots;
- and
- wherein a shuttle is located between said bolt and said lever, said shuttle sliding within said lockcase when said lever rotates.
1 more element
18:
- The privacy lock of claim 17 wherein said lever includes a wheel rotating on a hub and with an arm extending from said wheel, said handle located on said arm of said lever, said wheel including at least one slot therein, said slot engaging a post on said shuttle to translate said shuttle when said wheel rotates in response to forces applied to said arm through said handle.
19:
- The privacy lock of claim 13 wherein fasteners mount said lockcase to the jamb of the doorway.
20:
- The privacy lock of claim 19 wherein said lockcase includes a base plate on a surface thereof, and wherein jamb screws pass through said base plate and into the jamb, said base plate of said lockcase located outside of the jamb and adjacent to the jamb.
