Definitions
- the present invention relates to a forced entry resistant lock.
- Such fixing solution allows a burglar to tear the lock out of its seat in the leaf by acting on the heads of the screws or by tearing out said screws by using a screwdriver as a lever between the plate portion of the lock on which a threaded element is inserted and the underlying edge of said leaf.
- US 1 660 325 A discloses a lock having a casing and a bolt movable outward of the casing along a path, actuating means for the bolt comprising a pivot member movable outward in unison with the bolt, and an abutment on the casing serving to cause the bolt to tilt laterally of the path of the bolt while continuing its movement outwardly.
- the abutment co-acts with the bolt to prevent it from tilting back to its original position until after the bolt and pivot member are partially retracted.
- EP 1 243 729 A2 discloses a drive rod-actuated locking device comprising a connecting link which is slotted obliquely with respect to a displacement direction and which can be displaced longituidnally by a drive rod in a bolt housing, a pin engaging in the slot of the connecting link for sliding out or pulling back a lock in or out of a jamb closure piece.
- Two expander tongues articulated to the pin can slide in and out together with respect to the bolt housing, the tongues being hook shaped at the end to engage behind underucuts on the closure piece, while guides engage on the two expander tongues for an expanding movement at the end of sliding out.
- the aim of the present invention is to provide a forced entry resistant lock capable of obviating the cited limitations of known locks.
- an object of the invention is to provide a forced entry resistant lock capable of withstanding burglary attempts performed with a screwdriver or crowbar.
- Another object of the invention is to provide a forced entry resistant lock the extraction of which from its seat in the leaf is rendered far more difficult for a burglar.
- a further object of the invention is to devise a forced entry resistant lock that can be installed easily, like forced entry resistant locks of the known type.
- a forced entry resistant lock according to the invention is generally designated by the reference numeral 10.
- the forced entry resistant lock 10 is shown in Figures 1 and 2 inserted in the frame 12 of a leaf 13 provided with a glass pane, particularly with a double-glazing unit, 14.
- Said forced entry resistant lock 10 comprises:
- the engagement elements 17 and 18 are flat.
- Each engagement element 17 and 18, for example the engagement element 17, clearly shown in Figure 7 comprises a pivoting portion 26, with a through hole 27 for the movable pivot 21, and an engagement portion 28, from which the corresponding engagement tooth 19 protrudes.
- the coupling and rotation tab 30 has a curved or cam-shaped edge 32 designed to abut against an external cover 33 of the casing 15 proximate to the opening 16; this coupling determines the beginning of the rotation of the engagement element 17 during the translation movement of the movable pivot 21, as better described hereinafter.
- the abutment and stroke limiting tab 31 has a linear edge 34 that is adapted to couple to the external cover 33 on the opposite side proximate to the opening 16 but on the opposite side with respect to the coupling and rotation tab 30, so as to stop the rotation of the engagement element that began with the contact of the coupling and rotation tab 30 with the external cover 33.
- the tabs 30 and 31 are thus shaped so that with respect to the translation that the engagement element 17 and 18 performs carried by the movable pivot 21, the coupling and rotation tab 30 couples to the outer cover 33 before the abutment and stroke limiting tab 31.
- the engagement element 18 is to be understood as equal to the described engagement element 17 and mounted in a mirror-symmetrical manner on the same movable pivot 21.
- the movable pivot 21, to which both of said engagement elements 17 and 18 are pivoted, is arranged so as to slide with the ends inserted in corresponding slots 35, which have a linear extension and are defined on the casing 15 along a direction that is at right angles to the outer edge 36 of the frame 12 of the leaf 13 in which the lock 10 is inserted, i.e., a direction 38 from the inside toward the outside of the casing 15, which is substantially at right angles to the outer edge 37 of said casing 15.
- the means 23 for the translation of the movable pivot 21 in the direction 38, for the exit of the engagement elements 17 and 18 from inside the casing 15, are constituted by a moving body 40, designed to be coupled to corresponding actuation shafts 41 and 42 that are part of the hardware of which also the forced entry resistant lock 10 is a part.
- the moving body 40 is adapted to be translated in a direction that is perpendicular to the direction 38 of translation of the movable pivot 21, therefore parallel to the outer edge 36 of the frame 12 of the leaf 13.
- the moving body 40 is provided centrally with a cam-shaped slot 43 in which the movable pivot 21 is arranged so that it can slide.
- the cam-shaped slot 43 comprises two linear portions 45 and 46 and a diagonal intermediate portion 47.
- a first linear portion 45 is extended proximate to the external cover 33 of the casing 15.
- the second linear portion 46 is extended proximate to the inner cover 48 of the casing 15.
- the diagonal intermediate portion 47 is extended between the two linear portions 45 and 46.
- the translation of the moving body 40 causes a thrust, by means of the edges of the diagonal portion 47 of the cam-shaped slot 43, on the movable pivot 21, such as to induce the translation of the movable pivot 21 in the linear slots 35 of the casing 15, with consequent translation either toward the outside of the casing 15 or toward the inside of the casing 15 of the two engagement elements 17 and 18, as in Figures 3 to 6 .
- the moving body 40 in the present non-limiting example of embodiment of the invention, comprises two rod-like elements 40a and 40b, which are shown schematically in Figure 2 and diverge in order to surround the engagement elements 17 and 18 inside the casing 15, each one of which has a cam-shaped slot 43 as described above.
- the means 24 for the rotation of each engagement element 17 and 18 from an intermediate configuration for translation to a configuration for use are constituted by the coupling and rotation tab 30 and the abutment and stroke limiting tab 31, and by the external cover 33 with which the coupling and rotation tab 30 cooperates to rotate the engagement element, 17 or 18, to which it belongs, while the abutment and stroke limiting tab 31, by abutting against the external cover 33, stops the rotation of the engagement element 17 or 18 to which it belongs.
- the elastic means 25 for contrasting the rotation of the engagement elements 17 and 18 from the intermediate translation configuration to the configuration for use are constituted, for each engagement element 17 and 18, by a pusher lever 55 and 56 respectively.
- Each pusher lever 55 and 56 is coupled by one end 60 to the casing 15, while the opposite end 61 is pushed by an elastic element 62, for example a helical spring; the intermediate region of the pusher lever 55 and 56 acts on the coupling and rotation tab 30 of the corresponding engagement element 17 and 18, causing a rotation thereof that is equal and opposite to the rotation that occurs during the exit of the engagement element 17 and 18 from the casing 15, during the translation for retraction of the engagement element 17 and 18 inside the casing 15.
- an elastic element 62 for example a helical spring
- the pusher lever 57 causes the corresponding engagement element 17 and 18 to remain in its inactive and minimum-bulk configuration inside the casing 15.
- Each pusher lever 55 and 56 extends from a corresponding supporting block 65 and 66 by means of a bridge for pivoting thereto; the supporting block 65 and 66 is locked within the casing 15.
- the elastic pusher element 62 is interposed between the free end of the corresponding pusher lever and an insertion groove 67 defined within the casing 15.
- the forced entry resistant lock 10 also comprises an internal fixing plate 80, which is intended to allow the fixing of the casing 15 from the inside of the leaf, in the interspace 82 between the glass pane 14 and the frame 12 of the leaf 13.
- the casing 15 therefore has threaded holes 81 for corresponding screws 83, which are placed so as to pass through the internal fixing plate 80, which in turn is fixed to the inner face 85 of the frame 12.
- the forced entry resistant lock 10 then uses two engagement elements 17 and 18, which by acting in opposite directions inside the coupling 51 cooperate to prevent mutual extraction from said coupling 51, in practice rendering the closure compliant with the RC3 standard category, i.e., resistant to burglary attempts using a screwdriver and a crowbar; in fact, the attempt to disengage an engagement element from the coupling produces a greater engagement of the other engagement element.
- the flat shape of the engagement elements and the rotation around a single movable pivot instead of around two spaced pivots allow the lock 10 to have very small dimensions in height, depth and thickness, and this is very important especially in the application to door or window assemblies having a "minimalist" structure, i.e., with compact leaf and frame profiles that support glazings.
- the internal fixing plate 80 arranged in the space that exists between the frame 12 of the leaf 13 and the glass pane, ensures that the casing 15 cannot be extracted from the outside of said leaf.
- the invention provides a forced entry resistant lock that is capable of withstanding burglary attempts with a screwdriver or a crowbar.
- the invention provides a forced entry resistant lock the extraction of which from its seat in the leaf is made much more difficult for a burglar by way of its fixing by means of an inner fixing plate.

Description
- The present invention relates to a forced entry resistant lock.
- Currently, the most widespread international certifications for forced entry resistance for door and window assemblies, such as for example the EN1627 standard, entail various tests, including a manual test with burglary tools, which attempt to tear out the locking points of the hardware mounted on the leaf from the corresponding anchoring coupling mounted on the frame.
- Up to now, in door or window assemblies with shutter-like or tilt-and-turn opening with a forced entry resistance function it is known to use single hook and tumbler systems, which however, by using burglary tools such as screwdrivers and crowbars, can be extracted easily from the coupling seat, since they are anchored only on one side.
- Such known technical solutions, therefore, do not allow to attain the forced entry resistance class RC3, i.e., they are not resistant to the use of a screwdriver or crowbar by a burglar, according to the EN1627 standard.
- Currently known locks, moreover, are inserted in a corresponding seat in the leaf of a door or window assembly and are fixed to the edge of the leaf by means of threaded elements that generally are visible.
- Such fixing solution allows a burglar to tear the lock out of its seat in the leaf by acting on the heads of the screws or by tearing out said screws by using a screwdriver as a lever between the plate portion of the lock on which a threaded element is inserted and the underlying edge of said leaf.
