Definitions

  • the present invention relates to a manually or automatically operated lock for closures in general and, in particular, for rolling gates, according to the preamble of claim 1
  • the document DE-A-3 606 620 discloses a manually or automatically operated lock having the features of the pre-characterizing portion of the main claim.
  • the aim of the present invention is to provide a lock which can be operated either manually or automatically, for closure assemblies in general and for rolling gates in particular, which affords the possibility of indifferently using either a manual operation or an electric cutomatic operation of the lock, without the need of providing discrete closing means, but which remarkably simplify the construction of the lock so as to provide a flexible lock which can also be applied to existing rolling gates.
  • Another object of the present invention is to provide such a lock which can also be connected to an alarm system so as to enhance the safety characteristics thereof and which can be easily made starting from easily available elements and materials.
  • the manually and automatically operated lock for closures in general and rolling gates in particular, according to the present invention,has the main feature of comprising, inside a box-like holding body of the lock, which holding body has been overally indicated at the reference number 1, an electric motor 2 which, optionally, can be remotely controlled, and is provided with an opening code with a high safety electronic digital coding arrangement.
  • the electric motor 2 is coupled, through a kinematic chain or train, overally indicated at the reference number 3, and which will be disclosed in a more detailed way hereinafter, to a pair of opposite side rods 4 which are slidably associated with the body 1.
  • the kinematic chain or train 3 comprises a pinion 10, engaged with the shaft of the electric motor 2, which pinion meshes with a bevel tooth arrangement 11 of a first gear 12 provided with a reduced diameter cylindrical tooth arrangement 13 which, in turn, meshes with a second gear 14 having a smaller diameter tooth arrangement and engaging with the larger diameter tooth arrangement of a third gear 15.
  • first, second and third gears 12, 14 and 15 practically provide a movement reducing unit, with a high reduction ratio.
  • the third gear 15 engages with a middle element, overally indicated at the reference number 20, which comprises a bottom portion 21, shown in figures 9 and 10, provided with an outer tooth arrangement 22 for coupling with the third gear 15, and an inner groove 23 in which there is engaged a movable body 24, clearly shown in figures 7 and 8, which is provided with outer projections 25 having shapes which mate with the inner groove or slot 23 so that said movable body can be made rotatively rigid with the mentioned bottom portion 21.
  • the projections 25 engage with an inner groove or slot 26 of a top element 27 provided with an outer tooth arrangement 28, with which respectively engage a fourth gear 29 and a fifth gear 30 in turn engaging with a first and second gear wheels, indicated at 31 and 32, which are provided with eccentric pins 33 slidably housed in cross slots 34 formed on the rods 4 so as to cause said rods 4 to be translated as the gear wheels 31 and 32 turn.
  • the rods are caused, through the mentioned kinematic chain, to perform opening and closing movements, since the movable body of the middle element 20 rigidly connects, during the rotary movement, the bottom portion 21 and top portion 27.
  • a key cylinder 40 which can be a conventional piston type of cylinder, which is so designed that, as a key is operated, the movable body 24 is pushed against the counterbiassing force of the spring 51 which causes the movable body 24 to disengage from the bottom portion 21 and, accordingly, kinematically disengages said body from the electric motor.
  • a slot 50 into which the key can be introduced, so that as the key is turned, the movable body will be also turned and, accordingly, the top portion 27.
  • the tooth arrangement coupling the bottom portion, top portion and movable body are provided at their axial end portion with tapering parts provided for facilitating the mutual connection thereof, while absolutely preventing jams from occurring during the return movement.
  • the movable body 24 is so designed as to return to its starting position as the key is removed, said movable body being pushed by the counterbiassing spring 51 operating between said movable body and top portion.
  • the lock holding body or housing has a very small thickness and, accordingly, it is very suitable for an application to rolling gates.
  • connection between the gears and rods is made so that at the start and end of its stroke, the electric motor is not subjected to any load and, accordingly, it will provide a very efficient operation in a loaded condition.
