Special rules of classification within this subclass
In this subclass, only the movement essential for securing the wing is considered, e.g. a sliding bolt which is rotated on its axis to prevent its withdrawal is classified as having only a sliding movement.
Glossary of terms
In this subclass/group, the following terms (or expressions) are used with the meaning indicated:
In this subclass, the following terms are used with the meaning indicated:
Wing
General term for swingable, slidable, or otherwise movable doors or windows. This term also includes other movable structures such as drawers, lids of chests, car boots, or car bonnets, to which the operating, mounting, latching, or locking means covered by this class may be applied.
Frame
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
Primarily a device for releasing or securing any member, which requires a key or a permutation mechanism for release.
Bolt
A sliding, pivoted, or otherwise movable member such as is normally carried by a door to hold it shut by engagement with a keeper on the frame. It may be operated by hand directly or through mechanism or by a key; it may be a latch (see below);
Latch
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
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.
Synonyms and Keywords
In patent documents the following expressions "espagnolette lock", "multi-point lock" and "multipoint locking system" are often used as synonyms to indicate locks with simultaneously actuated bolts, e.g. by means of transmission bars, at well separated positions on the same wing.

Definition statement
This subclass/group covers:
