Concealed hinges provide a cleaner appearance than externally
mounted hinges, but they have a reputation for not being as strong. However, a
new concealed hinge provides high strength, vibration resistance, and allows
fast door removal and replacement.
Consisting of a door leaf and a frame leaf, the one-piece
pin/handle design locks in both open and closed positions. By removing the pin
handle out of its engaged detent, retracting the hinge pin from the frame leaf,
and locking the handle in the disengage detent, a single user can easily remove
the door from the frame. To replace the door, the user positions it on the
frame, slides the hinge pin into the frame leaf, and engages the pin in the
Tension springs resist vibration, maintaining handle position.
Gusset reinforcements increase axial and radial load capacity, and a
stainless-steel option provides corrosion resistance for use in harsh
Available in two frame leaf styles for left- or right-hand doors,
and a variety of door and frame configurations, the formed frame leaf provides a
standard 22.5-mm offset from inside the door to the frame-mounting surface. The
flat frame leaf accommodates non-traditional door and frame configurations, and
can be formed to provide offset heights up to 30.5 mm. Mounting holes can be
added to meet specific needs.
Targeting modular production applications where doors and frames
are fabricated in different locations, the hinge components are installed
separately using rivets, studs, standard machine screws, or by welding.
