Definitions

  • the present invention relates to an adjustable spring latch for locks.
  • Locks are generally constituted by a box-like body that contains a plurality of kinetic mechanisms actuated by a cylinder (a cylinder lock) and/or by a handle for moving a sliding latch and a spring latch.
  • the door leaf (the door, for example) on which the lock is installed can therefore be opened only by acting on the cylinder and/or on the handle: if the sliding latches are extracted, it will be necessary to make them return (via the rotation of the key in the cylinder or, in particular technical solutions, with a specific movement of the handle) and, in any case, it will be necessary to act specifically to make the spring latch return (specific rotation of the key in the cylinder and/or rotation of the handle). If the spring latch does not enter into the shape of the box-like body of the lock (therefore exiting from the respective opening present in the strike plate of the jamb) then the door leaf cannot be opened.
  • the presence of plays (gaps of imprecise breadth) between the door leaf and the frame can determine the non-insertion or partial insertion of the spring latch into the respective accommodation cavity defined in the frame (on the jamb).
  • the spring latch will need to be removed: in such configuration the screw remains facing outward and, given its narrow diameter, it can be easily damaged as a consequence of involuntary impacts. Damage to the screw on which the spring latch is coupled can render the entire lock unusable.
  • the aim of the present invention is to solve the above mentioned drawbacks, by providing an adjustable spring latch for locks that can be easily arranged in any configuration comprised between that of maximum protrusion and that of minimum protrusion.
  • an object of the invention is to provide an adjustable spring latch for locks that can easily be inverted without exposing any delicate part of the lock during such operations.
  • Another object of the invention is to provide an adjustable spring latch for locks that permits adjustments of the protrusion even to a considerable extent.
  • a still further object of the present invention is to provide an adjustable spring latch for locks which is low cost, easily and practically implemented and safe in use.
  • an adjustable spring latch for locks that comprise a box-like body inside which lever mechanisms are functionally associated for actuating at least one spring latch and at least one sliding latch, both of which can move from a retracted configuration to a protruding configuration with respect to said box-like body, characterized in that it comprises a through hole, aligned with the direction of sliding within the lock, for rotatably accommodating a tubular element which is provided with an internal threading, a fixed threaded pin, integral with a respective lever mechanism for actuating said spring latch, being externally threaded for coupling to said tubular element, the screwing and the unscrewing of said tubular element on said threaded pin causing the sliding of said spring latch between a configuration of maximum protrusion and a configuration of minimum protrusion with respect to said box-like body.
  • Figure 1 is a schematic cross-sectional front elevation view taken along a vertical plane of a spring latch according to the invention installed in the respective lock;
  • Figure 2 is a schematic cross-sectional view from above taken along a horizontal plane of the spring latch in Figure 1.
  • the reference numeral 1 generally designates an adjustable spring latch for locks A.
  • the locks A comprise a box-like body B inside which lever mechanisms are functionally associated for actuating at least one spring latch and at least one sliding latch, both of which can move from a retracted configuration to a protruding configuration with respect to the box-like body B.
  • the spring latch 1 comprises a through hole 2, aligned with the direction of sliding within the lock A, for rotatably accommodating a tubular element 3 which is provided with an internal threading.
  • a fixed threaded pin 4 integral with a respective lever mechanism for actuating the spring latch 1, is externally threaded for coupling to the tubular element 3.
  • the screwing and unscrewing of the tubular element 3 on the threaded pin 4 causes the sliding of the spring latch 1 between a configuration of maximum protrusion and a configuration of minimum protrusion with respect to the box-like body B.
  • the tubular element 3 is externally grooved.
  • the through hole 2 of the spring latch 1 is intercepted by a transverse channel 5 for accommodating a prong 6 for locking the tubular element 3.
  • the prong 6 interferes with the at least one groove 7, 8 of the tubular element 3, preventing translations thereof and permitting rotations thereof about its axis of symmetry.
  • the external grooves 7, 8 of the tubular element 3 can positively be at least two in number, for accommodating a portion of a respective prong 6, inserted into the channel 5 of the spring latch 1, according to different locked configurations which correspond to different protrusions of the spring latch 1 from the box-like body B.
  • the tubular element 3 can positively present, on its front directed toward the outside in the configuration of use, a shaping, of the type preferably selected from at least one notch (9), a toothing, a predefined shape structure and the like.
  • tubular element 3 can advantageously be made of material preferably selected from metals, metal alloys, polymers, composite materials, ceramic materials, sintered materials and combinations thereof.
  • the through hole 2 of the spring latch 1 has its axis coinciding with the straight line according to which the median sagittal plane and the front plane of the spring latch 1 proper intersect.
  • the spring latch 1 can, that is to say, be mounted according to one of the two possible directions of opening of the door leaf in which the lock A will be installed.
  • the spring latch 1 is removed for its inversion (in order to change, that is to say, the direction of opening of the lock A in which the spring latch 1 is installed) in reality a set of components comprising the spring latch 1 proper, the tubular element 3, and the prong 6 is extracted from the lock A.
  • the threaded pin 4 will not protrude from the box-like body 2 when the aforesaid set of components is removed, and therefore it will be protected from accidental impacts that could occur during the operations to invert the spring latch 1.
  • threaded pin 4 is conveniently integral with the rod C (generally known in the sector as a spring latch rod) which can slide within the box-like body B as a result of actuating at least one component selected from the handle and the key inserted in the rotor of the actuation cylinder.
  • rod C generally known in the sector as a spring latch rod
  • the present invention solves the above mentioned problems, by providing an adjustable spring latch 1 for locks A that can be easily arranged in any configuration comprised between that of maximum protrusion and that of minimum protrusion.
  • such adjustment can be carried out by way of screwing/unscrewing the element 3 on the pin 4 and/or by way of coupling the element 3 to the spring latch 1 using different grooves 7, 8 which are present on the element 3 and are adapted to engage a portion of the prong 6 inserted into the channel 5 (which interferes with the hole 2).
  • the spring latch 1 according to the invention can be inverted easily without exposing any delicate part of the lock A during such operations: as seen previously the pin 4 remains within the shape of the box like body B.
  • the adjustable spring latch 1 also makes it possible to adjust the protrusion to a considerable extent, by virtue of the possibility of coupling the element 3 to the hole 2 according to different configurations corresponding to the different grooves 7, 8 that are present on the element 3 proper (which partially accommodate the prong 6 for coupling the element 3 to the spring latch 1).
  • the materials employed, as well as the dimensions, may be any according to requirements and to the state of the art.
