Lock Casings TRIZ Cases
- Eccentric Lock Cover Plate Insert for Multi-Orientation Alignment
A rotatable eccentric insert lets one lock cover plate align with bolt and cylinder housings across multiple cabinet lock orientations.
- Cylinder Lock Bridge Assembly With Fixed-Pin Rotational Mounting
Fixed locking pins and a flattened bridge end enable simple rotational assembly of a cylinder lock, reducing alignment difficulty for novice users.
- Sliding Panel Lock Faceplate for Hidden Tool-Free Installation
Hidden plate connections replace visible screws in a sliding door or window lock, enabling faster installation and one faceplate for varied panel heights.
- Combination Rotary Lock Clutch Assembly Against Forced Opening
A clutch assembly blocks torque transfer to the lock tongue until the correct code is entered, preventing forced opening of the rotary lock.
- Sliding Door Locking Head Assembly for Tilted Sash Installation
A split locking head and guide channel let heavy sliding sashes be mounted in a tilted position, simplifying removal and reducing installer risk.
- Cylinder Lock Bridge Assembly With Fixed-Pin Rotational Alignment
Fixed locking pins and a flattened bridge end enable rotational self-alignment, making cylinder lock assembly and disassembly easier.
- Electronic Lock Housing Retention With Elastomeric Bore Engagement
Elastomeric retainers compress in the door bore to hold lock housing position and orientation, simplifying flush installation.
- Lock Cylinder Protective Cap With Movable Dust-Sealing Elements
Movable locking elements and snap-fit fastening let one lock cylinder cap maintain dust protection across different lock designs.
- Adjustable Latch Assembly for Knob and Lever Handle Compatibility
A movable cam blocker lets one latch fit knob or lever handles and switch backset positions for easier door installation.
- Modular Cylinder Spacer Assembly for Multi-Lock Compatibility
A releasable spacer with an attachment feature and ledge lets one spindle fit multiple lock cylinders, cutting variants and inventory cost.
- Lock Assembly Baffle Structure for Debris-Resistant Tamper Protection
A baffle with staged aperture sizing blocks debris from reaching the lock mechanism while preserving lock assembly installation and security.
- Double Cylinder Lock Rotator Design Against Picking and Snapping
Dual plungers lock the rotator until correct key insertion, helping block cam access after picking or cylinder snapping.
- Lockset Trim Cam Mechanism Against Indicator Tampering
A one-way cam and slider let the trim show locked or unlocked status while blocking indicator-driven tampering of the lock state.
- Composite Central Module for Pull-Resistant Locking Cylinders
Steel connecting elements in a die-cast zinc central module improve pull and twist resistance while lowering locking cylinder manufacturing cost.
- Double-Sided Nylon Lock Linkage for Press-and-Pull Door Opening
A linked press-and-pull lock body enables door opening from either side while simplifying transmission parts, assembly, and maintenance.
- Lock Mounting Plate Structure for Brake Element Anti-Sticking
A stamped lock mounting plate adds a recess and abutting portion to stop brake element sticking and improve assembly reliability.
- Night Latch Pushbar Assembly With Low-Torque Key Unlocking
A master cam and slide plate let the key unlock the night latch without retracting the latch, cutting operating torque and improving compliance.
- Double Lock Cylinder Ball Coupling for Pull-Out Resistance
Coaxial balls and a one-piece ring strengthen a double lock cylinder against pull-out manipulation while lowering core-to-bolt friction.
- Multipart Pin Lock Body for Lower-Cost Multi-Position Locking
A segmented lock body uses a main body and divider to simplify bore formation and cut the cost of multi-position pin locks.
- Anti-Intrusion Cylinder Lock With Radial Expansion Reinforcement
A steel bar, plastically deformable rod, and locking insert reinforce the radial expansion to resist forced entry and simplify assembly.
- Anti-Intrusion Cylinder Lock Reinforcement for Forced-Entry Resistance
A tempered-steel bar and stainless-steel lamina reinforce the lock’s radial expansion, resisting tearing and simplifying assembly.
- Modular Cylinder Lock with Segmented Channels for Easier Assembly
A contoured plate separates encoding and connection spaces, simplifying assembly while hard pastilles and closure plugs protect against forced entry.
