Abstract: In a device for opening and closing a window, a casement moves between a closed and an open position with respect to a stationary frame. This is done by a longitudinally displaceable toothed rack, which effects the movement of the casement of a carrier. In order to obtain a space saving, easy to operate device. Not only is the casement moved by the toothed rack, but the casement is also moved by a moveable closing element in the frame between its latching position and unlatching position with a stationary carrier located on the frame. Both carriers are connected respectively to the toothed rack by means of an independent coupling, which is rendered effective and ineffective at an associated change-over location. These two change-over locations are arranged in a specific place in the path of longitudinal displacement of the toothed rack, respond to the associated coupling and are automatically effective.

Abstract: A door opening/closing apparatus, which can cause quick and smooth start of movement of a sliding door in an emergency, without any possibility of breakage of the door due to quick movement, so that it can be used reliably and safely. When an operating member is released from its lock, it is pulled along with the sliding door, by a uniform force. To start movement of the operating member, a pushing member mounted on a slidable member is pushed by the spring forces of two coil springs, thus aiding the operation of pushing the operating member and permitting quick and smooth start of movement of the operating member, sliding door, etc. With the screwing of an adjustment screw, the spring force of an adjustment spring is adjusted. The adjusted spring force causes a pushing member to be pushed against a guide member via a pivotal member and a pushing member to effect adjustment of the speed of movement of the operating member for braking action.
