Definitions

  • the present invention relates to a door opener with a monitoring system, suitable for locking and unlocking a door and providing a signal indicating the state of the door.
  • This invention falls within the sector of closing devices with access control for doors, windows and closures in general.
  • Electric and electronic door openers are access control devices which allow locking/unlocking a door.
  • Said door openers are assembled in the frame of the door and have a retaining bolt for the catch of the lock of the door in the closed position.
  • Said door openers have an internal mechanism that is locked or unlocked by means of the activation or deactivation of a solenoid. In an unlocked position, the internal mechanism allows a rotational movement of the bolt, and it allows the catch of the door to slide over said bolt when opening the door.
  • the bolt of the door opener generally has a height adjustable front part and is provided with a closing stop in charge of preventing the movement of the catch and the rotation of the door towards the open position when the internal mechanism keeps the bolt of the door opener locked.
  • Electric or electronic door openers having a monitored function are able to send a signal to an access control system, indicating the open or closed state of the door at all times.
  • Monitored door openers today have a drive cam assembled with the possibility of rotation in the casing of the door opener and arranged in front of the front part of the bolt. Said cam is operated by the latch of the door and when said door reaches the closed position, the drive cam acts by means of an arm on a microswitch of the monitoring system, providing a signal indicating that the door is closed.
  • Each one of documents DE102004037827A1 , DE102014104094A1 , EP3599328A1 , and ES1070806U discloses a door opener having, in essence, a bolt comprised of a bolt base mounted to pivot about a rotating shaft and a front part that is adjustable in height with respect to the bolt base between a lower position and an upper position away from the rotating shaft.
  • the adjustable front part comprises a stop defining a lower plane for retaining a catch of a door in a closed position.
  • the door opener further comprises an internal mechanism for locking and unlocking the bolt, a monitoring system for monitoring the state of the door, and a drive cam that is located facing the front part of the bolt and that is moved by the catch of the door from an inoperative position to an operative position in which the cam drives the monitoring system.
  • a groove configured to receive the cam is defined both on a front face and in the stop of the front part.
  • the monitored door opener object of the invention is of the type described in the preamble of the main claim, comprising: a bolt assembled on a rotating shaft; a height adjustable front part with respect to the bolt and provided with a stop defining a lower plane for retaining a catch of a door in a closed position; an internal mechanism for locking and unlocking the bolt, activating a solenoid, and a drive cam of a monitoring system for monitoring the state of the door, facing the front part of the bolt, and said cam being moved by the catch of the door from an inoperative position to an operative position in which said cam drives the monitoring system by providing a signal about the closed state of the door.
  • This door opener has certain technical features which ensure the effective contact of the catch of the door with the drive cam of the monitoring system for monitoring the state of the door, in all the height regulation positions of the front part of the bolt and without reducing the useful space for engagement of the catch with the bolt of the door opener.
  • the adjustable front part of the door opener comprises a receiving groove of the cam, said groove being defined on the front face and in the stop of said adjustable front part.
  • the cam and the front part are sized such that said front part is movable between a lower position in which the end of the cam is arranged inside the groove of the stop of the adjustable front part, and an upper position away from the rotating shaft of the bolt, in which the end of the cam is arranged considerably flush with the lower plane of the stop of the bolt or inside the groove of said stop.
  • This feature allows, in the upper and most unfavourable position of the adjustable front part, no empty space to be left between the cam activating the microswitch and the stop of the adjustable front part locking the catch of the door, whereby ensuring that no errors occur in the activation of the monitoring system and that the catch of the door is not engaged with the cam, causing it to deform or break.
  • said groove has on the front face of the adjustable front part a depth equal to or greater than the thickness of the cam, such that when said cam is operated by the catch of the door, it is housed in the groove of the front part and does not reduce the length defined in the lower plane of the stop of the front part for engaging and locking the catch of the door; which entails an advantage with respect to door openers existing today, in which the cam activating the microswitch is kept in a projecting position with respect to the surface of the adjustable front part when it is operated by the catch of the door, said cam reducing the useful space defined in the adjustable front part for locking the catch of the door.
  • the cam can be formed by a one-piece body having a length sufficient for the end thereof to be housed in the groove of the stop of the adjustable front part when said front part is in the upper, most unfavourable position; or it may comprise fixing means for fixing a supplement, which increases its length and forms the end of the cam intended for being housed in the groove of the stop of the adjustable front part, preventing a free space from being left between the stop of the adjustable front part and the end of the cam.
  • Figures 1 to 7 represent a door opener (1) provided with a bolt (2) with a rotating shaft (21) and having a height adjustable front part (3) between a lower position represented in Figures 1 to 4 and an upper position represented in Figures 5 to 7 , and fixed to the bolt (2) by means of screws (4).
  • the mentioned front part (3) has in its front-upper area a stop (31) defining a lower plane (32) for retaining the catch (C) of the lock of a door when said door reaches a closed position, as shown in Figures 4 and 7 .
  • the door opener (1) has an internal mechanism (not represented) for locking and unlocking the bolt (2), which can be driven by means of a solenoid, and a drive cam (51) of a monitoring system (5) for monitoring the state of the door, facing the front part (3) of the bolt (2).
  • the cam (51), formed in this exemplary embodiment by a one-piece body, is moved by the catch (C) of the door from an inoperative position represented in Figures 3 and 6 , to an operative position represented in Figures 4 and 7 when said door reaches the closed position.
  • the adjustable front part (3) of the bolt has a groove 33 affecting both the front face and the stop (31) of said adjustable front part (3).
  • Both the cam (51) and the front part (3) are sized such that said front part (3) is movable between: a lower position, shown in Figures 3 and 4 , in which the end of the cam (51) is arranged inside the groove (33) of the stop (31), and an upper position in which the end of the cam is kept inside the groove (33) of the stop (31) or considerably flush with the lower plane (32) of the mentioned stop (31), as shown in Figures 6 and 7 .
  • the sizing of the cam (51) and of the front part (3) of the bolt (2) prevent a space from being defined between the lower plane (32) of the stop (31) of the bolt and the end of the cam (51), in which the end of the catch (C) can be introduced without moving the cam (51) towards the operative position, causing a failure in the monitoring system for monitoring the state of the door.
  • the groove (33) has on the front face of the front part (3) a depth equal to or greater than the thickness of the cam (51), such that in the operative position the cam (51) is arranged inside the mentioned groove (33) as shown in Figures 4 and 7 .
  • the cam (51) therefore does not project from the front surface of the front part (3) and does not reduce the length (L) defined in the lower plane (32) of the adjustable stop (31) for supporting and retaining the catch (C) in the closed position of the door.
  • the cam (51) comprises a supplement (52) fixed to the body of the cam (51) by fixing means (53) represented by a screw, said supplement (52) forming the end of the cam (51) intended for being housed in the groove (33) of the front part (3) of the bolt (2).
