NOTE

In this class, the following terms are used with the meanings indicated :

bonnets, to which the operating, mounting, latching, or locking
means covered by this class may be applied;
- "Frame" means any member to which a wing may be held by a
fastening device. It does not include a framework forming part
of the wing, but it may be another wing;
- "Lock" means primarily a device for releasing or securing any
member, which requires a key or a permutation mechanism for
release. In groups E05B 1/00 to E05B 9/00, E05B 13/00 to E05B 17/00,

latch (see (5) below);
- "Latch" means a bolt arranged to be moved to the releasing
position against the force of a spring, or some other returning
force, when a wing meets the frame on closing, so that it does
not have to be operated by hand to secure the wing, but only to
open it;
- "Hasp" means a member hinged to the frame or wing so that it
can be moved towards the face of the wing or frame and secured
thereto, e.g. by a turn-button, by a padlock and staple.
