The invention relates to a closure device for doors, comprising: a bolt (2) made of ferromagnetic material provided with a spring (21) pushing it to a retracted position; and an electric door opener (1) comprising: a rotary latch (11) provided with a rear body (111) and with a front body (112) the height of which can be adjusted, fixed to a front face of the rear body (111), an electromechanical mechanism for the locking and unlocking of the latch in a closing position, and magnetic means which are located in a visible position on the front face of the front body (112) of the latch and are directly opposite the movable bolt (2), without any element interposed between same, in the closing position of the door, moving said bolt (2) into a front cavity (113) of the front body (112) of the latch (11).

The present invention relates to an electric strike with a monitoring system, comprising: a box (1), a swivelling latch (2), an internal locking and unlocking mechanism which can be actuated by the core (10) of a coil (8), a PCB circuit (13), two PCB connecting strips (11), a monitoring system for monitoring the state of the internal mechanism comprising an internal microswitch assembly (14) connected to a PCB circuit (13) of the strike and which can be actuated by the core (10) of the coil (8). The present invention further comprises a monitoring system for monitoring the state of a door, provided with a microswitch assembly (12) connected to the PCB circuit (13) of the strike and actuated by an actuation lever (3) located in the latch of the strike, when the door is in the closed position and the latch of the door actuates said actuation lever (3).

The present invention relates to an electric door opener, comprising a box (1), a latch (2), means for locking the latch (2), able to be electrically actuated, and comprising an internal lever (3) and an automatic mechanism for retaining the internal lever (3) in an unlocked position of the latch from the moment the door opener is electrically actuated until the door is opened. Said automatic mechanism comprises: a cam (6) mounted on the latch (2) by means of a rotating shaft (21); a compression spring (7) that causes the cam (6) to rotate towards an inoperative front position and, a strap (8) solidly attached to the internal lever (3), able to be actuated by the cam (6) and which maintains the latch in the unlocked position from the moment the door opener is electrically powered until the door is opened.
