• the latch can ⁇ be " normally retracted by moving the handle or by turning the key in the actuation cylinder.
• the latch is actuated by the movement of the cylinder, which is functionally associated with the key.
• the secondary leaf can be locked manually (by
• the handle 15 means of suitable locking couplings, generally on the ceiling and floor) or also can be opened by means of a respective handle (in this case, the handle is intended to retract any locking couplings).
• the handle of the secondary leaf is not functional when the main leaf is closed (in particular if it is locked with a key) in order to avoid break-ins.
• the strike lock is provided with a pusher that acts on a protruding pivot of the lock, releasing the retraction of the bolt and of the latch: at this point, the action of a pusher (generally the same one) on the
• This pivot according to a particularly efficient constructive solution disclosed by this same Applicant in EP0620342, is installed at the front end 5 wall of the bolt: this embodiment ensures that it is not accessible (for break- in purposes) and therefore allows to maintain a high level of security for the lock that comprises it.
• the aim of the present invention is to provide a universal lock for swing-doors, i.e., a lock adapted to be fitted to any kind of swing-door, fully 25 achieving all of the tasks required by the specific installation.
• an object of the present invention is to provide a lock for swing-doors of the universal type in order to reduce inventories of material held in stock, by unifying into a single component a plurality of different articles suitable for specific applications.
• Another object of the present invention is to provide a universal lock for swing-doors that can be adapted, even during installation with the aid of simple tools available to any technician, to any installation application.
• Another object of the present invention is to provide a universal lock for swing-doors that has low costs, is relatively simple to provide in practice and is safe in application.
• the present universal lock for swing- doors of the type comprising a box-like body for containing a movement cylinder that is associated with a respective actuation key, a rotating bush associated with a handle, suitable lever systems for the translational motion of at least one latch and of at least one bolt, functionally associated with said handle and said cylinder, and a pivot that protrudes, in contrast with elastic transmission means, said at least one bolt being locked in the extracted configuration when said pivot protrudes, and being free, for a retraction which is forced by an external force, when said pivot is pressed to retract, contrasting said elastic transmission means, by an external force, characterized in that it comprises means for the mechanical deactivation of said pivot.

• Figure 2 is an enlarged-scale side view of the detail A according to a first embodiment of a universal lock for swing-doors according to the invention
• Figure 3 is an enlarged-scale side view of the detail A according to a second embodiment of a universal lock for swing-doors according to the invention
• Figure 4 is an enlarged-scale side view of the detail A according to a third embodiment of a universal lock for swing-doors according to the invention.
• the reference numeral 1 generally designates a universal lock for swing-doors.
• the lock 1 comprises a box-like body 2 for containing a movement cylinder 3, which is associated with a respective actuation key (not visible in the accompanying figures), a rotating bush 4 which is associated with a handle (not visible in the accompanying figures), suitable lever systems 5, for the translational motion of at least one latch 6 and of at least one bolt 7, which are functionally associated with the handle and with the cylinder 3.
• the lock 1 also comprises a closing sensor 8, which is designed to lock/release the latch 6 when it is forced to retract by an external action or when it is normally extracted by the action of the spring associated therewith.
• the lock 1 further comprises a pivot 9 which protrudes, in contrast with elastic transmission means (said elastic means, not visible in the figure, are constituted normally by at least one axially acting spring, which tends to keep the pivot in the protruding configuration).
• the at least one bolt 7 is locked in the extracted configuration when the pivot 9 protrudes, and is free, for optional retraction forced by an external force (in particular as a consequence of a pushing action applied to the bolt 7 in the direction for its retraction) when the pivot 9 is pressed to retract, contrasting the elastic transmission means, by an external force.
• the force applied to the pivot 9 can be the same that will be applied to the bolt 7, for example by means of a pusher provided in the strike lock (of the secondary leaf), which will first press the pivot 9, releasing the retrograde stroke of the bolt 7, and then pushes inward the entire bolt 7 to completely open the lock 1.
• the lock 1 comprises means for mechanical deactivation of the pivot 9: by deactivating the pivot 9 (and thus eliminating its effects on the bolt 7 and optionally on the transmissions 10 and on the latch 6), the lock 1 behaves like a normal lock for single-leaf swing-doors (of the simple or antipanic type) or for a double leaf of the simple type (without antipanic function).
• the pivot 9 is accommodated within a hole 11 of the bolt 7 that is arranged on the sagittal plane thereof: the hole 11 is parallel to the direction of translational motion (entry and exit) of the bolt 7.
• the hole 11 and one end 12 of the pivot 9 lead to a unit 13 for retracting the bolt 7.
• the means for mechanical deactivation of the pivot 9 comprise a stem 14, which is contained entirely in the hole 11 and can slide therein.
• the end that faces outward is provided with elements for detachable coupling with a head 15, the portion of which that protrudes from the front of the bolt 7 constitutes the actual pivot 9.
• the elements for coupling the stem 14 to the corresponding head 15 are constituted by a threaded hole (provided on the top of the stem 14): accordingly, the head 15 of the pivot 9 comprises a respective shank, whose dimensions and shape are complementary to those of the hole, which can be screwed into such hole.
• the head 15 of the pivot 9 is removed from the threaded hole, it is possible to provide a suitable plug whose dimensions and shape are complementary to those of the hole in order to close it detachably; in this manner, it is not possible to access the unit 13 in any way, not even by using break-in tools. It is convenient to provide on the top of the pivot 9 (therefore on the head 15) a suitable contoured recess for actuation (screwing and unscrewing) by means of a specific tool.
• the means for mechanical deactivation of the pivot 9 comprise a pin 16, which can perform a translational motion in a transverse receptacle 17 of the bolt 7.
• the receptacle 17 is open in a lower region and therefore leads to the hole 11 that accommodates the pivot 9.
• the pin 16 can perform a translational motion, by way of external action, from a free configuration for the pivot 9, in which it is accommodated completely in the receptacle 17, to a locking configuration of the pivot 9, in which its end protrudes from the receptacle 17 in the hole 11 , interfering with the pivot 9 and locking it in the hole 11 by mechanical forcing.
• the pivot 9 by adopting different levels of diameter and constituting a shoulder therein: with this constructive choice, in addition to preventing the unintended extraction of the pivot from the hole 11 (it is sufficient for it to have a diameter that tapers at the front edge of the bolt 7 to utilize the shoulder of the pivot 9 as a stop element), the locking of the pivot 9 in the chosen configuration is ensured, maintaining the shoulder upstream or downstream of the pin 16 that protrudes from the receptacle 17.
• the hole 11 comprises a suitable contoured region 18 at the retraction unit 13 and the means for mechanical deactivation of the pivot 9 comprise a shaft 19, which is contained entirely in the hole 11 and can slide therein and is provided at its innermost end with an eccentric block 20, which is jointly connected to the pivot 9 on the opposite side with respect to its portion that protrudes from the bolt 7.
• the pivot 9 can rotate about its own axis.
• the eccentric block 20 can move between one configuration, in which the pivot 9 is active for the retraction of the bolt 7, for coupling with a respective recess 21 formed in the retraction unit 13 at the contoured region 18 of the hole 11, and a configuration in which the pivot 9 is passive and is not associated with the retraction unit 13 of the bolt 7, for freedom of movement of the pivot 9 and of the block 20 with respect to the retraction unit 13.
• the pivot 9 comprises, in its portion that protrudes from the bolt 7, suitable grip areas 22 for a tool that is suitable for turning the pivot 9 and therefore the shaft 19 jointly connected thereto.
• the eccentric block 20 exits and reenters the recess 21 provided in the retraction unit 13 as a consequence of rotations of the pivot 9 performed with the tool engaged in the respective grip area 22.
• the bolt 7 comprises at least one suitable transverse dowel 23, which is accommodated within a respective pocket 27 of the bolt 7 that interferes with the shaft 19 to lock it. It has thus been shown that the invention achieves the proposed aim and objects.
