CPC Definition - Subclass E05C
This place covers:

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.
In this place, 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. |
In patent documents, the following words/expressions are often used as synonyms:
- "espagnolette lock", "multi-point lock" and "multipoint locking system" to indicate locks with simultaneously actuated bolts, e.g. by means of transmission bars, at well separated positions on the same wing.
This place covers:
Fastening devices comprising a rectilinearly movable bolt. The bolt can have either latching or non latching action. The bolt can be moved with an operating handle or equivalent member moving rigidly or non rigidly with the bolt. This group also cover cylindrical or tubular latches.
This place does not cover:
Arrangements of simultaneously actuated bolts at well-separated positions on the same frame | |
Devices for holding a wing open comprising a sliding securing member | |
Automatic catches with sliding bolts | |
Locks in which a sliding latch is used also as a locking bolt | |
Lock with a sliding bolt without provision of latching | |
Vehicle locks with a rectilinearly movable bolt |
Attention is drawn to the following places, which may be of interest for search:
Cylindrical or tubular locks |
This place covers:
Fastening devices comprising a pivotally or rotatively movable bolt. The bolt can have either latching or non latching action. The bolt can be moved with an operating handle or equivalent member moving rigidly or non rigidly with the bolt.
This place does not cover:
Arrangements of simultaneously actuated bolts at well-separated positions on the same frame | |
Devices for holding a wing open comprising a single pivoting securing member | |
Latches with wedging action, tilt-plates | |

This place covers:
Fastening devices with bolts moving otherwise than only rectilinearly and only pivotally or rotatively, e.g. bolts moving axially and turning about their axis to secure the wing.
This place does not cover:
