Title: Solenoid actuated window or door hinge pin - has guiding seat with actuating spring and releasing solenoid
Inventor: HESS HERBERT
IPC: E05D15/52
Filed: 1974-05-03
Abstract: The electrically actuated locking system is used for locking of hinge pins of rotating and tilting windows and doors. The electrical actuation is used instead of mechanical actuating linkages which release certain pins so that the frame can either rotate or tilt. The pin of the fitting has a flange which contacts the stop on locking. This pin is held in the locked, forward position in which it engages with the bearing sleeve. When the solenoid is energised then the pin is withdrawn against the force of the spring. When the current is switched off then the pin moves forward and engages with the sleeve. This hinge pin system can be used for large windows which are readily operated because it only involves actuation of an electrical switch.
