Definition statement
This subclass covers:

Bolts or fastening devices for swingable, slidable, or otherwise movable wings, e.g. doors or windows. This subclass has the following structure:

Fastening devices characterised by the way the bolt is moved.

Fastening devices specially adapted for two wings.

Arrangements of simultaneously actuated bolts or other securing devices at well separated positions on the same wing.

Fastening devices for holding wings open.

Other devices specially designed for securing wings.

References relevant to classification in this subclass
This subclass does not cover:

Buckles; Similar fasteners for interconnecting straps or the like, e.g. for safety belts

Hinges or pivots

Accessories for sliding or lifting wings

Suspension arrangements for wings

Closers or openers for wings, braking devices

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, the following terms (or expressions) 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.

Fastening devices with bolts moving rectilinearly
Definition statement
This group covers:
