  • FIGS. 20 and 21 a further embodiment of the lock 1 is shown, wherein a time delay 49 for the opening of the lock 1 and an alarm device 50 are provided, whereby a pre-alarm before opening is possible.
  • Both the time delay 49 and the alarm device 50 are formed purely mechanically within the lock 1, so that no wiring of electrical control and / or power supply lines on the wing of the door is required. However, it is also an external arrangement for electronic time delay conceivable.
  • a signal output can be effected by the alarm device 50. This may be, for example, an alarm siren, which may possibly deter a person wishing to use the door without authorization, or even trigger a signal on a monitoring device in a gate, thereby informing security guards.
  • the alarm device 50 has, in the lock 1, a magnet 52 displaceably displaced against a spring 51, which cooperates with a magnetic field sensor 53, for example a reed contact or a Hall element, which can be arranged on the frame side in the strike plate 4.
  • the spring 51 and the magnet 52 is guided in a fixed in the lock 1 sleeve 54.
  • the Magnet 52 is connected to a pull rod 55 having at its end a pulling head 56 which abuts in the rest position of the actuating handle 9 on an extension 57 of the pusher disc 11, 11 ', whereby the magnet 52 against the force of the spring 51 of the cuff. 3 is shifted away and the magnetic field sensor 53 is not activated.
  • the purely mechanical time delay 49 consists of a damping element with a displaceably arranged in a cylinder 58 piston 59, on which a pull rod 60 is arranged.
  • the pull rod 60 has at its end also a pulling head 56 which cooperates with the extension 57 of the pusher disc 11, 11 '.
  • a driver 61 is further arranged, which cooperates with a suitably designed rocker switch 34. It can also find alternative damping elements application.
  • the actuating handle 9 is pressed and thus the extension 57 of the pusher disc 11, 11 'pivoted in the direction of the cuff 3, the acted upon by the spring 62 piston 59 is also displaced in the cylinder 58 in the direction of the cuff 3.
  • the piston 59 is guided with a slight gap to the inner wall of the cylinder, whereby a damping of the sliding movement of the piston 59 is caused due to the forced thereby slow overflow of air from one side of the piston to the other side of the piston in the cylinder 58, including a bore or a valve in the Piston 59 may be provided. It can also be one other damping medium than the ambient air, such as oil, be provided.
