DEVICES FOR MOVING WINGS INTO OPEN OR CLOSED POSITION

**Definition:** 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 control means, and safety devices such as obstruction detection devices.

**Glossary:** - Braking device: Devices constructed to slow down the movement of wings - Closer: Gravity-, spring- or power-operated device constructed to provide a closing force to wings over a substantial part of their movement; includes devices for assisting users in wing-movement or for wing-counterbalancing; a closer can take the shape of a self-closing hinge - Opener: Gravity-, spring- or power-operated device constructed to provide an opening force to wings over a substantial part of their movement; includes devices for assisting users in wing-movement or for wing-counterbalancing - Operating mechanism for wings: Mechanism constructed to convert force inputs from a user, motor, opener or closer into movement of wings - Self-closing hinge: Gravity- or spring-operated hinge constructed to provide a closing force to wings over a substantial part of their movement; includes devices for wing-counterbalancing - Vehicle: Land vehicles, e.g. cars, trucks, buses or trains - Wing: Pivotable, slideable, or otherwise moveable part of doors, windows, flaps, covers or similar structures to prevent traffic through a passageway in building construction and outfitting, fences, domestic appliances, vehicles and furniture; the term also includes drawers, lids of chests, car boots/trunks or car bonnets/hoods
