The seemingly-endless range of hinge options one can choose from can be daunting. But it is the design and purpose of each hinge that has everything to do with aesthetics and functionality; but often, utility will trump looks.
Hinges are unsung heroes in the world of motion since they are impressively strong for the job they are aligned with, and are often up to ten times stronger than the application, for which, they are assigned.
What Are Specialty Hinges?
Specialty hinges play a unique role in the motion-control arena since they ensure that specialized application needs are met. Standard hinges are not designed for highly-specialized needs which can demand higher degrees of functionality and durability. Specialized needs can include circumstances that deal with severe weather conditions, high traffic volume, and security issues, for example. Special-purpose hinges are designed for somewhat unusual or very unusual applications.
Let’s take a look at a few types of specialty hinges:
- Tornado-resistant hinges are constructed to remain in tact and withstand extreme wind speeds as well as high impact form airborne debris.
- Fire-rated pocket-pivot hinges which are, typically, made of cast steel, can be used on fire-doors. This type of hinge can be utilized on hollow-metal or steel-covered composite doors that are fire-rated for up to 3 hours and wood fire doors for 20 minutes.
- Mortise interim hinges are the perfect door-opening solution when the door and the frame require two hinges of different sizes.
- Double-acting hinges are the perfect solution for folding dividers or screens that are called on to fold in both directions or need to be stowed away at any time.
- Lift-up hinges are heavy-duty and are used for overhead compartments that one would find in RVs, buses, trains, aircraft and furniture built-ins. They are surface-mounted and entirely invisible when the door is closed.
- Mirror hinges are designed with brake-action pivots and are often used on vanity-type mirrors. The wedge action allows for tight secure fastening as well as almost effortless removal.
- Self-closing hinges allow doors or drawers to softly close, preventing any annoying slamming or pinched finger. The slow-close is achieved via an inner spring that controls the hinge’s movement.
- Soss hinges are hidden when in their closed position and go by the name, concealed barrel-shaped hinges. They are often used with doors, windows and cabinets where aesthetics plays a role almost as much as functionality. A soss hinge allows a cabinet door, for example, to close flush with the frame, resulting in a clean line.
- Kimana hinges possess a unique movement design that caters to opening and closing flap and drop-down doors. Vertical cabinet doors can be opened regardless of whether the cabinet bottom rests on another panel or if the top of the cabinet is crowned with a decorative panel.
- Energy transfer hinges go, also, by the name ‘electrified’ hinges which allow power to be transferred from the frame into the door. These hinges can be exposed or concealed. The maximum voltage that is allowed in electrified hinges is 48 volts due to safety reasons.
Specialty hinges meet the many and varied motion-control needs in every industry, world-wide. Medical, commercial, automotive, military, construction, transportation and aviation industries all rely on specialty hinges to ensure motion-control movements are met with absolute precision and seamless dependability.
