Electromechanical retaining device for door with door closer - has setting screw for adjusting release force of ratchet lever cooperating with sliding block of door closer

摘要

The electromechanical retaining device holds the door in the required position using a pivot lever (17), operated via an electromagnet (19) and having a ratchet lever (1) at the opposite end to the electromagnet (19), with a ratchet nose (2) cooperating with the sliding block (3) of the door closer. The ratchet release force can be adjusted via a setting screw (4) in the operative position of the retaining device. Pref. the setting screw (4) is incorporated in the pivot lever (17) and cooperates with a rear retaining arm (9) of the ratchet lever (1). ADVANTAGE - Simple adjustment for different door closer sizes etc.
