Definitions

  • the present invention relates to a lock opening device, particularly for independently actuated locks.
  • Locks are currently known which are actuated by a handle by means of an element shaped like a right parallelepiped with a square base, known as square pin, which when fixed to the handle, generally by means of a grub screw, and inserted in the rotatable bush for actuating the latch of the lock, transmits the rotation of the handle to the bush, which accordingly actuates the lock.
  • the bush in fact has a through hole with a square cross-section which is shaped complementarily to the square pin, so as to accommodate it and so that it can be turned by it simultaneously with the handle.
  • Locks actuated by a square pin which is inserted in their actuation bush and is fixed at its opposite ends to two handles arranged at the opposite faces of the door are currently widespread.
  • one of the two handles always actuates the lock, while the other one can be disabled, for example by means of a key, so as to not actuate the lock.
  • locks of this type are provided for doors that allow the free flow of users in one direction, the one faced by the handle that always actuates the lock, while in the other direction the flow of users can be prevented, by disabling the corresponding handle to actuate the lock to open the door, or can be limited to users who have the key for enabling the lock.
  • such locks are used for so-called antipanic doors, in which, as is known, a push bar is connected to the lock so as to always actuate the lock, while on the opposite face of the door there is a handle which can be disabled to actuate the lock.
  • the lock has two latch actuation bushes which are mutually adjacent and coaxial and are both provided with holes for the insertion of the corresponding square pins.
  • each handle is connected to a corresponding actuation bush by means of a square pin and the action of one handle is therefore substantially independent of the action of the other one.
  • a first one of these bushes always actuates the lock, while the second one can be disabled to this function, and therefore the corresponding handle does not allow to open the lock, which in any case can be actuated by the other handle.
  • the square pins are generally connected to each other at their ends that face each other when they are inserted in the corresponding holes of the actuation bushes.
  • one square pin has a threaded longitudinal tab which can mate with a corresponding threaded hole provided at the end of the other square pin, so that if the square pins are not fastened to each other they can rotate with respect to each other, with the tab rotating within the hole, remaining coupled longitudinally by means of the thread which prevents their mutual extraction.
  • This solution is preferred with respect to a structure in which the square pins are not mutually connected, since it obviates a drawback that occurs in the latter structure and is constituted by the risk of extraction of the square pins from the actuation bushes.
  • the aim of the present invention is to provide a lock opening device, particularly for independently actuated locks, which avoids extraction of the square pins from the actuation bushes.
  • an object of the invention is to provide a lock opening device which allows easy mutual rotation of the square pins, avoiding the risk of their mutual coupling and ensuring their coaxial arrangement.
  • Another object of the invention is to provide a lock opening device which is easy to adjust so that it can be adapted easily to the thickness of the door to which the lock is applied.
  • Another object of the invention is to propose a lock opening device which is structurally simple and easy to use and can be manufactured with low costs.
  • a lock opening device particularly for independently actuated locks, which comprises two square pins, each of which can be associated, at one of its ends, with one of the handles, which are provided correspondingly on opposite faces of a door, said square pins being insertable, at their other end, in two corresponding bushes for actuating the latch which are adjacent and coaxial, each bush being provided with a through hole which has a square cross-section and is shaped to accommodate the corresponding square pin for the actuation of the lock, characterized in that each one of said square pins has a longitudinal through hole for the insertion of a rod which can slide and rotate within said longitudinal hole, substantially coaxially, said rod having, at least at its ends, means for contrasting the extraction of said square pins, each of said means being fitted on said rod at the corresponding said longitudinal hole.
  • the reference numeral 10 generally designates a lock opening device, particularly for independently actuated locks, which comprises two elements shaped like right parallelepipeds with a square base, known as square pins 11, each of which can be associated, at one of its ends, with one of the two handles 12 provided correspondingly on opposite faces of a door 13.
  • the square pins 11 can be inserted in two corresponding adjacent and coaxial bushes 14 for actuating a latch 15, each provided with a through hole 16 which has a square cross-section and is shaped to accommodate the corresponding square pin 11 to actuate the lock.
  • each one of the two square pins 11 has a longitudinal through hole 17 for the insertion of a rod 18 which can slide and rotate therein substantially coaxially.
  • the rod 18 has, at least at its ends, means for contrasting the extraction of the square pins 11, which are adapted to prevent the extraction of the square pins 11 from the rod 18 once such rod has been inserted therein at the longitudinal holes 17.
  • such extraction contrasting means comprise snap rings 19, which can be inserted in grooves 20 which are formed perimetrically on the rod 18, at least at its ends.
  • the snap rings 19 can be engaged by abutment by the square pins 11 fitted on the rod 18, so as to contrast their mutual extraction.
  • the rod 18 is provided with multiple perimetric grooves 20, which can be engaged by the snap rings 19 and are distributed along its longitudinal extension.
  • the user can select the groove 20 into which the snap ring 19 is to be inserted in order to retain in abutment the square pins 11 in a manner which is adequate for the thickness of the door 13 on which the lock is fitted, thus shortening the rod 18 by the extent that exceeds the portion comprised between the snap rings 19, for example by sawing it off.
  • the use of the opening device 10 according to the invention is as follows.
  • the user When the lock is fitted, the user inserts the square pins 11, which are suitable for the thickness of the door 13, in the respective bushes 14 and then inserts the rod 18 in the square pins 11.
  • the user engages with the snap rings 19 the grooves 20 that delimit the length of the rod that is suitable for the thickness of the door 13, i.e., the portion of the rod 18 that is engaged by the square pins 11.
  • the operation of the opening device 10 according to the invention is as follows.
  • Each one of the handles 12 acts, by way of the corresponding square pin 11, on the corresponding bush 14 for actuating the latch 15.
  • the two square pins 11 can rotate independently on the rod 18, so that the two handles 12 likewise actuate independently the latch 15.
  • handles 12 are mutually retained by the respective square pins 11, to which they are fixed by way of the grub screws 21, since such square pins 11 are retained on each other by the rod 18 in abutment against the corresponding snap rings 19.
  • an opening device 10 can be used for antipanic doors, with the panic bar connected, in a per se known manner, to one of the two square pins 11 of the lock, in order to open the door by pushing, while a handle, which can optionally be disabled to actuate the lock, is connected to the other square pin 11.
  • the invention achieves the proposed aim and objects, providing a lock opening device, particularly for independently actuated locks, which avoids extracting the square pins from the actuation bushes, retaining them together by means of the through rod, which acts as a retention element as well as a rotation pivot.
  • an opening device for locks according to the invention allows easy mutual rotation of the square pins, avoiding the risk of their rigid coupling and simultaneously ensuring their coaxiality.
  • a lock opening device is further easy to adjust so that it can be adapted easily to the thickness of the door to which the lock is applied.
  • the materials used may be any according to requirements and to the state of the art.
