Definitions

  • the object of the invention is an electric strike for doors, having a device for monitoring the open or closed state of the door, and which comprises: a box in which a rotational latch for retaining the bolt of a lock in a closed position of a door, an unlocking mechanism of the rotational latch, which can be actuated electrically, and means for monitoring the state of the door are assembled.
  • This invention can be applied to the field dedicated to the manufacture of electric strikes for doors.
  • the utility model U201630978 describes an electric strike for doors, with a device for monitoring the state of the door which comprises a box in which the following are assembled: - a rotational latch that defines a cavity for the housing of a bolt of a lock, and which is enabled to rotate between an open position, in which the movement of the bolt of the lock is allowed in the opening direction of the door, and a closed position, in which it retains the bolt of the lock in a closed position of the door; - an unlocking mechanism of the latch, which can be actuated electrically; and - a device for monitoring the state of the door.
  • This monitoring device comprises a rotational slider, enabled to rotate with respect to the rotational latch, which mechanically actuates a microswitch when it is moved towards a first position by the bolt of the lock of a door when said door is in the closed position, and which releases said microswitch when the door is opened and the bolt of the lock no longer actuates on said rotational slider.
  • the unlocking mechanism of the rotational latch comprises a set of levers, which tend to be kept in a locked position of the rotational latch by the action of springs, and a solenoid that upon being electrically powered causes the movement of said levers towards an unlocked position of the rotational latch.
  • the aforementioned rotational slider responsible for actuating the microswitch, is located in a recess made in an intermediate area of the rotational latch, such that during the operation of the strike a number of forces and frictions are produced that may provoke undesired retention of the rotational latch.
  • the open or closed state of the door is monitored by a microswitch that is mechanically actuated by an arm defined in the rotational slider and that extends through the inside of the box of the strike, from an intermediate area to one of the sides of the box in which the aforementioned microswitch is found.
  • This monitoring device in addition to being exposed to friction and forces that may cause operationing errors and breakdown thereof, requires the existence of a space inside the strike for the placement and movement of the arm responsible for actuating the microswitch.
  • the technical problem posed is the development of an electric strike for doors, of the type mentioned above, capable of monitoring the state of the door without using mechanical components, such as the arm and microswitch indicated above and which allow the operational state of the strike to be seen more easily.
  • the electric strike for doors object of the invention has technical characteristics intended to satisfactorily solve the problem posed, avoiding the drawbacks of the mechanical actuation of the means for monitoring the state of the door and ensuring reliable operation of the electric strike, and in particular as regards avoiding the risk of locking the rotational latch.
  • this electric strike incorporates means for monitoring the state of the door associated with the strike, which comprise: an electrical switch or reed switch assembled in a fixed position and a magnet assembled in the rotational slider, such that the magnet faces the electrical switch or reed switch when the door is in the closed position and the bolt of the lock of the door holds the rotational slider down, the magnetic field of the magnet causing the activation and deactivation of the electrical switch,
  • An additional characteristic of the invention consists of the fact that it comprises a helical or torsion spring that acts with the opposite ends against the rotational latch and against the rotational slider tending to separate them in an angular direction using a common rotation shaft thereof as a reference.
  • the electric strike for doors object of the invention comprises a box (1) in which a rotational latch (2) that defines a front cavity for the housing of the bolt of a lock (not shown) of a door is assembled, and which is enabled to rotate between an open position, in which the movement of the bolt of the lock of a door is allowed in the opening direction of said door, and a closed position, in which it prevents the movement of the bolt towards the open position.
  • the electric strike has terminals (3) for connecting power cables and control cables of an unlocking mechanism (4) of the rotational latch (2) on one of the smaller sides of the box (1), having known characteristics and generally shown in Figures 3 and 4 .
  • FIG. 3 shows that the rotational latch (2) is assembled on a rotation shaft (5) and has a housing in the central area thereof in which a rotational slider (6) is housed, also assembled on the rotation shaft (5) of the rotational latch (2), but with the possibility of independent rotation.
  • This strike comprises means for monitoring the open or closed state of the door, visible in Figure 3 and comprising an electrical switch (7) or reed switch arranged in a fixed position, and a magnet (8) assembled in the rotational slider (6); such that when said rotational slider (6) is moved towards the inside of the box (1) by the action of the bolt of the lock of the door, the magnet (8) is arranged facing the electrical switch (7) or reed switch, actuating it by means of the magnetic field thereof.
  • this strike has a spring (9), in this case helical, that acts with the opposite ends against the rotational slider (6) and against the rotational latch (2) tending to keep them separated in an angular direction and exerting sufficient elastic force against them to prevent the locking or undesired retention of the rotational latch.
