Last Updated Version: 2017.08
DEVICES FOR MOVING WINGS INTO OPEN OR CLOSED POSITION; CHECKS FOR WINGS; WING FITTINGS NOT OTHERWISE PROVIDED FOR, CONCERNED WITH THE FUNCTIONING OF THE WING
Definition statement

This place covers:

Devices for moving wings, such as doors or windows, into open or closed position; checks for wings, such as doors or windows; wing fittings not otherwise provided for, concerned with the functioning of the wing.

Gravity-, spring-, or power-operated devices to provide a force input for opening or closing wings, such as door openers and door closers, self-closing hinges and hinges with wing-counterbalancing function.

Also covered are operating mechanisms for wings constructed to convert the force input from a user, motor, opener or closer into movement of a wing, such as cable-, cord-, chain-, or belt-drives, lifting arms, rack and pinion drives or screw and nut arrangements.

The subclass furthermore covers braking devices, stops and buffers for wings as well as controlling means, such as remote wireless controls means, and safety devices such as obstruction detection devices.

A number of main groups in this sub-class contain a large number of older documents that were classified administratively. These documents have not yet been reclassified to the sub-groups and are indexed with E05Y 2800/00. This index should not be used for classification.

E05F 2700/00 is an old indexing scheme. It can be used for search but should not be used for classification.

Under E05Y 2900/00 and lower an indexing scheme exists for information on the application or use of the devices. The indexing scheme is shared with the sub-class E05D. It is mandatory to allocate the appropriate indexing code of E05Y 2900/00, if the application or use is not implicit from the classification titles.
