Description

UNIVERSAL SECURITY LOCK Technical field
The present invention relates to a universal security lock. Background art The advancement of locks is tightly linked to the advancement of methods for picking them.
It is known that potential thieves use sheet-like elements to try to force the opening of a lock installed on a door: this is possible by inserting an element between the jamb and the edge of the door in order to dislodge (in some cases) the latch or bolt, making it retract into its seat inside the lock and allowing to open the door.
The insertion of sheet-like elements (for example metallic laminas and/or credit cards) therefore causes conventional locks to provide substantially limited security. New types of security lock comprise suitable plungers which exit from the front of the lock: when the plunger is in the extracted configuration (which corresponds to the open door), the latch can be drawn back (made to retract into the respective seat of the lock) simply by pressing it to force the spring that keeps it protruding; when instead the plunger is in the retracted configuration (accommodated within the lock, because the door is closed and its end rests against the front of the selvage that faces the edge of the lock and lies proximate to it), the latch is blocked and cannot be retracted by pressing it. The only way to release the latch (in this condition in which the plunger is retracted) is to act on the handle or (in cases in which the lock is provided with) on the key.
The ill-intentioned person who intends to perform a break-in by using a sheet-like element would find this impossible due to the blocking action provided by the retracted plunger.
This type of lock can also be used in the case of a single-leaf door provided with an antipanic handle (or panic bar). From the outside, release of the latch would be possible only by means of the key, while from the inside, by acting on the handle (or on the panic bar) it is always possible to retract the latch.
This type of lock therefore allows a high level of protection against break-in actions and at the same time can be installed on single-leaf doors for emergency exits with associated antipanic handles (and/or panic bars).
However, in the case of two-leaf doors it is not possible to achieve the same results.
In fact, whereas acting on the handle (or bar) of the main leaf actuates (in a manner similar to what has been already described) the retraction of the latch, this retraction is not possible by acting on the handle (or bar) of the secondary leaf and the lock does not open, keeping both leaves in the closed condition.
It is evident that this condition does not comply with the requirements of an emergency exit.
Disclosure of the invention
The aim of the present invention is to provide a universal security lock which can be actuated to open both by the handle (or bar) of the leaf on which it is installed and by the handle (or bar) of the secondary leaf on which its latch engages.
Within this aim, an object of the present invention is to provide a universal security lock which is suitable for the movement (and retraction, if the handles and/or bars of the main leaf and/or of the second leaf are actuated) also of any bolts to ensure emergency opening. Another object of the present invention is to provide a universal security lock which has low costs, is relatively simple to provide in practice and is safe in application.
This aim and these objects, as well as others which will become better apparent hereinafter, are achieved by the present universal security lock of the type that comprises at least one latch and at least one bolt, which can perform a translational motion from a configuration in which they protrude from the front edge of the lock to a configuration for accommodation within respective internal seats, and at least one retractable plunger, which is forced elastically to protrude from the front edge of said lock, said plunger being adapted to block the at least one latch when arranged in the protruding configuration, characterized in that it comprises a bracket which is coupled movably to the outer box-like body of said lock and is functionally associated with at least one of said bolts by being connected mechanically to an end which faces, and lies proximate to, the portion that is jointly connected to said plunger and is adapted, even indirectly, to block said at least one latch, said end connected to said bracket, during the retraction of said bolt associated therewith, being forced against said latch blocking portion to disengage said end from said latch and consequently release said end.

With reference to the figures, the reference numeral 1 generally designates a universal security lock.
The security lock 1 comprises at least one latch 2 and at least one bolt 3 (in particular, there is generally an actual bolt 3 and there are suitable additional bolts, which are associated with suitable transmission elements 4 and protrude in regions which are more distant from the lock 1 of the door). The latch 2 and the bolts 3 can perform a translational motion from a configuration in which they protrude from its front edge 5 to a configuration in which they are accommodated within respective internal seats.
The lock 1 further comprises at least one retractable plunger 6, which is forced elastically to protrude from the front edge 5 of the lock 1. The plunger 6 is adapted to lock the at least one latch 2 when it is arranged in the protruding configuration.
The lock 1 comprises a bracket 7, which is coupled to a box-like body 8: the coupling is such as to ensure at least one degree of freedom to the bracket 7. The bracket 7 is functionally associated with at least one of the bolts
3 and is connected mechanically to an end which faces, and lies proximate to, a portion 9 which is jointly connected to the plunger 6 and is adapted to block the at least one latch 2.
The end connected to the bracket 7, during the retraction of the bolt 3 associated therewith, is forced against the blocking portion 9 of the latch 2 for the disengagement of the blocking portion 9 from the latch 2 and the consequent release of the portion 9.
The plunger 6 is functionally associated with a contoured plate 10, which is pivoted to the box-like body 8 and can rotate with respect to its pivoting axis 11 by way of the action of said plunger.
The plate 10 is coupled to the latch 2 for its actuated blocking.
In particular, the lock 1 also comprises a panel 12, which is pivoted to the box-like body 8 and is coupled to the plate 10.
The panel 12 is provided, at one of its ends 13, with the portion 9 for blocking the plunger 6; therefore, the retraction of the plunger 6 entails a rotation of the plate 10 with respect to the pivoting axis 11 (this rotation occurs because the plunger 6 no longer forces the plate 10 with a counterclockwise rotation and the spring 14 can turn it in the opposite direction) and an approach of the blocking portion 9 of the panel 12 in abutment against a tab 15 of the latch 2 to block it in the extracted configuration.
The panel 12 comprises a protrusion 16, which can slide within a slotted profile 17 of the bracket 7: the slotted profile 17 is constituted substantially by a slot which is provided with at least one raised portion 18, which is designed to modify the path of the protrusion 16 while it slides inside it. As an alternative, it would be possible to provide a slotted profile 17 which has an irregular shape (with bends) in order to obtain the same result.
The translational motion of the bracket 7, as a consequence of the retraction of the bolt 3, causes a movement of the protrusion 16, by way of the action of the raised portion 18, with consequent rotation of the plate 10 (rigidly coupled to the panel 12) about its pivoting axis 11 and a spacing of the blocking portion 9 of the panel 12 from the tab 15 of the latch 2 to release it. The plate 10 comprises an upper beak 19, which is substantially hook-shaped for abutment against a transverse stem 20 which is jointly connected to the plunger 6.
When a translational motion of the plunger 6 occurs, an identical translational motion of the hook-shaped beak 19 and a consequent rotation of the plate 10 with respect to its pivoting axis 11 can be observed.
In particular, when the door is open the plunger 6 is extracted (it protrudes with respect to the edge 5) and the beak 19 is retracted: the stem
20 in fact rests on the bottom 21 of the concavity of the beak 19 and the panel 12 coupled to the plate 10 is rigidly coupled by the plate 10 so that its blocking portion 9 is separated from the tab 15 of the plunger 6 (as shown in Figure 1).
When the door is closed (or in any case the plunger 6 is kept within the respective seat of the lock 1 ), the stem 20 is separated from the bottom
21 of the concavity of the beak 19 and lies proximate to its end 22. By way of the action of the spring 14, the plate 10 can rotate clockwise (with reference, purely by way of example, to the embodiment shown in the figure) and the panel 12 coupled thereto is rigidly coupled by the plate 10 with its locking portion 9 rested against the tab 15 of the latch 2 for corresponding locking. It should be noted that the lock 1 according to the invention comprises a handle seat 23 which is provided with a projection 24 which faces the blocking portion 9 and is proximate thereto.
When the square pivot, accommodated within the handle seat 23 and associated with said handle, rotates, the projection 24 is forced to rest against the portion 9 (or proximate thereto) to move it away from the tab 15 of the latch 2, with consequent release thereof.
Of course, the lock also comprises a cylinder which is actuated by a respective key and is designed to move the at least one bolt 5 : the movement of the bolt 5 also entails the actions for releasing the latch 2 by utilizing the bracket 7, which is subjected to a translational motion by the bolts 5 and acts on the plate 10 and the panel 12.
The lock 1 according to the invention, therefore, if installed on a single-leaf door, can be used both with a handle of the traditional type and with antipanic handles and/or panic bars. By acting on the handle, the retraction of the latch 2 and of the bolts 3 is in fact produced (in this case, the lock 1 must comprise suitable transmission elements dedicated to this operation).
At the same time, maximum security against break-ins is ensured, because retraction of the latch 2 by using flexible laminas inserted in the gap between the jamb and the door is not possible: the latch 2 in fact cannot return into the lock 1 as long as the plunger 6 is in a retracted configuration, unless one acts on the handle or cylinder with the key in order to achieve this result.
If one intends to install the lock 1 according to the invention on a two-leaf door, with known types of lock it would not be possible to install antipanic handles and/or panic bars on both leaves.
The secondary leaf in fact could not be opened, since the latch 2 would remain in the protruding configuration, preventing its opening.
With the lock 1 according to the invention, use is possible both with a handle of the traditional type and with antipanic handles and/or panic bars on both leaves.
The antipanic handle (panic bar) provided on the secondary leaf in fact would act by means of a pusher on the bolt 3, making it retract: in this condition, the retrograde translational motion of the bolt 3 would entail the consequent translational motion of the bracket 7. The translational motion of the bracket 7 would force the protrusion to move along the slotted profile 17, consequently changing trajectory at the raised portion 18.
The change of trajectory would ensure a rotary motion of the panel 12, which would move the blocking portion 9 away from the tab 15, releasing the latch 2 and allowing correct antipanic operation.
It has thus been shown that the invention achieves the intended aim and objects.
The invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims.
All the details may further be replaced with other technically equivalent ones.
In the exemplary embodiments shown, individual characteristics, given in relation to specific examples, may actually be interchanged with other different characteristics that exist in other exemplary embodiments.
Moreover, it is noted that anything found to be already known during the patenting process is understood not to be claimed and to be the subject of a disclaimer.
In practice, the materials used, as well as the shapes and dimensions, may be any according to requirements without thereby abandoning the scope of the protection of the appended claims.
Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly such reference signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference signs.
