Definitions

  • the present invention is related to an automatic lock of the those which act mechanically and which, on closing the door, remain with the bolt or bolts introduced into the frame as well as the latch without the use of the key being needed.
  • a characteristic of this lock is the presence of a push button on the inside face which permits the opening both of the latch and of the bolt by depression of said push button.
  • a further characteristic is opening of all the anchoring means from the outside by means of a quarter turn of a key.
  • This lock permits the incorporation of remote opening mechanisms.
  • This lock is specially designed as an anti-panic locking system, in which when opening, by manipulating the handle, the bolts are automatically released.
  • the present invention comprises an automatic lock based on a special arrangement of springs, rocker arms and trips which permit the locking of the door and consequently the lodging of the bolts in the frame in an automatic fashion without the use of the key, and, when opening, its unlocking with no more than the depressing of a push button or in its absence by simply turning the key through 45°.
  • the invention proposed herein consists of an automatic lock which permits the locking of the door on which it is installed by means of the displacement of one or various bolts by tripping, pushed by springs tightened by the latch on closing the door.
  • this lock can be actuated by any type of key, be it conventional, by electronic card, or by means of a remote signal, in which case these additional electronic devices would be the only items requiring electric power.
  • a remote operating system makes sense for example in the case of access gates to community housing where in addition to having direct access it is possible to have remote opening by means of a doorman located at a distance as well as from each dwelling.
  • the essential operating principle of this lock consists in taking advantage of the energy which is applied to the door panel on closing, storing said energy in several springs which shall act to displace the locking bolts in an automatic manner.
  • Part of this energy shall also be employed on opening the door, withdrawing the bolts and releasing the latch.
  • Both the bolt and the latch have their housings in the door frame in order to permit locking after closure, that is, when the panel has turned to situate itself in the angular position coincident with the frame.
  • This arm which is hinged at one end, has the opposite end fixed to a spring in such a manner that during the turning movement imposed by the pusher joined to the latch, the spring is tightened.
  • This arm also has, at a point between the pusher and the end joined to the spring, a supporting projection which passes over a rocker arm installed on the bolt.
  • This rocker arm is in an inclined position through the effect of a spring, the axle pin of which is perpendicular to the floor of the lock encasement.
  • the bolt Since the bolt has a linear movement and the pusher joined to the arm describes an arc of a circle, the bolt is not pushed over its entire course; however, by inertia, the bolt continues its displacement to the end of its travel.
  • a second rocker arm by means of a spring, applies force with its extremity on a side face of the bolt and, as the bolt has a boss which surpasses the position of the rocker arm when the bolt reaches its end of travel point, the return of the bolt is impeded whilst the second spring is maintained in tension.
  • the opening of the door can be carried out either from the inside or from the outside.
  • rocker arm acts on the latch to permit the door to be opened.
  • the latch of which it has been said it is only provided with a linear movement may also be above to rotate with respect to an off-centre axis in the proximity of the face opposite to the outside oblique plane.
  • This plate constitutes the arm of a rocker joined in turn to the rocker arm which has released the bolt.
  • a spring that pulls on the latch partly turns it, the projection ceasing to be opposite the mortise in which it was held and, in addition, the latch comes to rest on a second spring which hampers its rotation.
  • the invention likewise contemplates the possibility of replacing the springs with elements which perform the same function, like pneumatic cylinders of those which accumulate energy through the compression of a gas.
  • a possible variation which is included in the second preferred embodiment consists in having a latch which does not have the capacity to turn.
  • This plate is immobilised by means of a rocker arm which rests on the bolt.
  • the plate ceases to be prevented from turning and permits the latch to pass over it.
  • the plate is returned to its position by means of a spring waiting for the door to be closed, tripping the bolt which in turn shall block the plate of the latch.
  • Figure 1 Shows a theoretical schematic of a first embodiment of the invention when the lock permits the opening of the door; and in addition a detail is included showing the geometrical shape of the latch.
  • Figure 2 shows a theoretical schematic of the same first embodiment of the invention in the locked position with the bolt housed in the frame.
  • Figure 3 shows a theoretical schematic of a second embodiment of the invention in which the latch cannot rotate and the bolt is not locking the door.
  • Figure 4 shows a theoretical schematic of the same second embodiment of the invention in which the lock is locking the door and, in addition, a detail is included of the latch and the swivelling plate installed in the frame viewed from above.
  • Figure 5 shows a spring of pneumatic type which can be employed instead of the spiral type springs.
  • the present invention relates to an automatic lock which mainly, by means of rocker arms and springs, is capable of locking and unlocking the door with the bolt with no need to turn a key.
  • an automatic lock is considered held in a case (1) installed in the side of a door opposite the hinges and facing housings (2) and (3) present in the frame (4).
  • the preferred embodiments include only one bolt (5) which serves to lock the door when it is shut.
  • the latch (6) In parallel with this bolt (5) is located the latch (6) in the detail of which is shown its axle pin (6.1) contiguous with the face (6.4) parallel to the door and around which it can pivot when it is not impeded because the projection (6.3) situated on the opposite side is housed in the mortise (7.4) of the plate (7.1) of a rocker arm (7).
  • the rocker arm (7) rests, according to the detail view, on the latch (6) by pivoting on an axle pin (7.3) the base (8) of which is common to the support for the axle pin (6.1) of the latch (6), to one of the ends of the spring (9) which withdraws the latch (6) and to one of the ends of the spring (10) for recovering the latch (6).
  • This common base (8) shows the possibility of a linear displacement which permits the withdrawal of the latch (6) when the frame (4) rests on its oblique face (6.2).
  • an arm (12) is pushed by a pusher (11.1) joined to the base (8) by means of a joining structure (11).
  • the arm (12) pivots about its lower extremity (12.1) and the other extremity is connected to a spring (20) which is tightened.
  • a support (12.2) which passes over a rocker arm (13) joined to the bolt (5).
  • This rocker arm (13) is passed over because it is inclined favourably through the effect of a spring (13.1), for which reason the support (12.2) of the arm (12) compresses the spring (13.1) forcing the rotation of the rocker arm about its axle pin (13.2).
  • the arm (12) likewise recovers its initial position pulled by the spring (20) and in turn pulling the bolt (5) since the rocker arm (13) is not facing its extremity favourably.
  • figure 1 an arc is drawn consisting of alternate dashes and dots showing the locus of the support point (12.2) of the arm (12).
  • the bolt (5) continues by inertia on its path until the boss (5.1) passes over the position of the end (15.1) of the other rocker arm (15).
  • the opening occurs when either a push button (16) is depressed from the inside face of the door, or a key (17) is operated.
  • This linkage permits not only the release of the bolt (5) but also of the projection (6.3) of the latch (6) in order that it be withdrawn through the action of the spring (9) which works in traction and complete its rotation through the force of the frame on the latch (6).
  • FIG 3 is shown a second embodiment of the invention in which the latch (6) does not have the possibility to turn, being able to move only in a linear fashion.
  • This tongue (18) swivels about its axle pin (18.1) arranged perpendicular to the path of the latch (6) when it is released by means of a rocker arm (19).
  • this rocker arm (19) is held firmly by the bolt (5) so that, when the bolt (5) is withdrawn, the tongue (18) can rotate and the latch (6) is free to leave its housing (3).
  • the tongue (18) recovers its position by means of a spring which is not shown in the figures.
  • Figure 4 is a repetition of the same schematic showing the bolt (5) inserted in the housing (2) of the frame (4) and resting against one end of the rocker arm (19) of the frame (4) in order to maintain the tongue (18) blocked and therefore the latch (6).
  • Figure 5 is a detail of a spring of pneumatic type which can replace the conventional spiral type springs.
