Surface Mounted Barn Door Lock Jamb Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Barn doors typically lack effective locking mechanisms, making it difficult to provide privacy or security, especially since existing locks designed for pivoting or pocket doors are not suitable due to the offset alignment of barn doors with the wall plane.
Innovation Solution
A lockset system for barn doors that includes a strike with a cylindrical shape and a lockcase with a handling assembly, allowing the bolt to translate in and out of the strike for locking and unlocking, which can be easily installed on the doorway jamb without requiring significant modification, and includes an emergency access mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a known prior art lock with handle/knob mounted to the door and bolt engaging the doorway jamb is used, then the lock can provide privacy function, but it is not effective because the barn door is offset from the wall plane and not aligned coplanar with the wall plane
Solution Approach 1:
The lockset is repositioned from being mounted on the door to being mounted on the doorway jamb, changing the spatial dimension of installation. This allows the bolt to engage the strike on the jamb rather than requiring the door to be coplanar with the wall, thus accommodating the barn door's offset alignment while maintaining locking effectiveness
Solution Approach 2:
Instead of mounting the lock on the door and having the bolt engage the jamb (traditional approach), the invention inverts this by mounting the lock on the jamb and having the bolt engage a strike on the door. This inversion allows the lock to function effectively with barn doors that are offset from the wall plane
2Reliability
If a lockset is installed on a barn door that was not originally configured with a lock, then privacy and security are provided, but the installation requires significant modification to the doorway and barn door
Solution Approach 1:
The lockset is divided into separate components: a lockset assembly that mounts to the jamb and a strike assembly that mounts to the barn door. This segmentation allows each component to be installed independently on pre-drilled holes, reducing installation complexity and avoiding the need for significant modification to the doorway structure
Solution Approach 2:
The strike assembly includes a cylindrical shape with a hollow core that receives the bolt, pre-configured to align with the lockset. This preliminary configuration of the strike receptacle allows for straightforward installation on barn doors that were not originally designed with locks, minimizing modification requirements
3Shape
If a lockset is designed to mount within a recess in the jamb, then a clean appearance is achieved, but the jamb must be modified to create the recess
Solution Approach 1:
The lockset body is designed as a self-contained unit that can be surface-mounted to the jamb using a base plate, eliminating the need to create a permanent recess in the jamb. This approach trades the permanent structural modification for a removable, surface-mounted solution that achieves a clean appearance without costly jamb reconstruction

AI summary
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.
