Definitions

  • the present invention relates to a universal key for opening doors from the inside and from the outside.
  • a possible solution to this problem may be to provide specifically designed locks, but this solution does not lend itself easily in the case of domestic environments and especially in the case of already existing locks, since it would entail the complete replacement of the locks,
  • the aim of the present invention is to provide a universal key which allows opening both from the inside and from the outside without thereby having to perform the complete replacement of the lock.
  • a particular object of the invention is to provide a universal key which can be applied extremely rapidly and easily to existing locks, without requiring any complicated or special interventions.
  • Still another object of the present invention is to provide a universal key which, by virtue of its peculiar constructive characteristics, is capable of giving the greatest assurances of reliability and safety in use.
  • Not least object of the present invention is to provide a universal key which is easily obtainable starting from elements and materials commonly commercially available and which is furthermore competitive from a merely economical point of view.
  • a universal key for opening doors from the inside and from the outside characterized in that it comprises a key body insertable in a lock and having a grip and a stem with a radially protruding ward, at the free end of said stem there being coupling means for the engagement of the coupling tang of an auxiliary grip element accessible on the opposite side of the lock with respect to the side of insertion of said key body.
  • the universal key structure for opening doors from the inside and from the outside comprises a key body 2 which, in a per se known manner, is insertable in a lock, generally indicated by the reference numeral 3.
  • the key body 2 has a grip 5 from which there extends a stem 6 having a ward 7 e.g. of the radially protruding type.
  • coupling means are defined at the free end of the stem 6 and allow to couple the tang 10 of an auxiliary grip 11 which is accessible on the side of the lock 3 opposite to the side of insertion of the key body 2.
  • said coupling means are constituted by a threaded portion 20 defined by the stem 6, which inserts in a threaded seat 21 defined on the tang 10.
  • FIG. 2 A similar solution is illustrated in figure 2, wherein the coupling means are defined by a polygonal seat 30, provided for example on the stem 6, and a polygonal protrusion 31 which is provided on the tang l0.
  • the key body 2 is inserted in the lock 3 and then the tang 10 is applied to the other side of the lock, it being possible to force said tang so as to make the coupling permanent or to apply it so as to allow release of the coupling.
  • a very important aspect of the invention resides in the fact that the above described key is also easily applicable to already existing locks, without thereby having to perform integral replacements or modifications of said lock.
  • the materials employed, as well as the contingent shapes and dimensions may be any according to the requirements.
