Definitions
- the present invention relates to a forced entry resistant lock.
- This 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.

- a forced entry resistant lock characterized in that it comprises
- a forced entry resistant lock according to the invention is generally designated by the reference numeral 10.
- the lock 10 comprises:
- the particularity of the forced entry resistant lock 10 resides in that it comprises means for fixing to the casing 15 a plate 80 for preventing extraction from the opposite side with respect to the opening 16.
- 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.
- the casing 15 is inserted in a corresponding seat 90 defined in the frame 12.
- the extraction-preventing plate 80 has greater dimensions at least in one direction with respect to the opening 91 of the seat 90, so as to abut and be pressed against the edges of the opening 91.
- the casing 15 then has threaded holes 81 for corresponding screws 83; the screws 83 are arranged so as to pass through the extraction-preventing plate 80.
- the extraction-preventing plate 80 in particular is adapted to be mounted in an interspace 82 between the glazing 14 and the frame 12 of the leaf 13.
- the extraction-preventing plate 80 prevents a burglar from extracting the casing 15 from its seat 90, since the dimensions of the extraction-preventing plate 80 prevent its passage through the opening 91 of the seat 90.
- the casing 15 is supported by an outer cover 33 and the extraction-preventing plate 80 is fixed only to the casing 15 by means of the screws 83, which pull it, or push it if there is contact, toward the casing 15.
- the extraction-preventing plate 80 is made of metallic material, but it is to be understood that it can also be made of other similar and equivalent materials.
- the invention also relates to a leaf 13 for a door or window assembly of the shutter-like or tilt-and-turn type, of the kind comprising a frame 12 that is arranged so as to surround a glass pane 14 and defines with it an interspace 82, characterized in that it comprises, within a corresponding flush mounting seat 90, a forced entry resistant lock 10 comprising

- the movement means for the engagement elements 17 and 18 comprise:
- the engagement elements 17 and 18 are plate-like.
- Each engagement element 17 and 18, for example the engagement element 17, clearly shown in Figure 5 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 outer cover 33 of the casing 15 proximate to the opening 16; such coupling determines the beginning of the rotation of the engagement element 17 during the translation movement of the mobile 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 outer 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 outer cover 33.
- the tabs 30 and 31 are thus shaped so that, with respect to the translation movement 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 the 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 outer 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 and 4 .
- 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 outer 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 outer 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 55 and 56 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 relies therefore on two engagement elements 17 and 18, which by acting in opposite directions inside the coupling 51 cooperate to prevent mutual extraction from the 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 extraction-preventing plate 80 arranged in the interspace 82 that exists between the frame 12 of the leaf 13 and the glass pane 14, ensures that the casing 15 cannot be extracted from the outside of the leaf.

Abstract
- a casing (15) with an opening (16) for one or more engagement elements (17, 18),
- means for moving the one or more engagement elements (17, 18) from an inactive configuration to a configuration for use, and
- means for fixing to the casing (15) a plate (80) for preventing extraction from the opposite side with respect to the opening (16).
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.
- This 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.
- The aim of the present invention is to provide a forced entry resistant lock capable of obviating the cited limitations of known locks.
- Within this aim, an object of the invention is to devise a forced entry resistant lock capable of withstanding burglary attempts performed with a screwdriver or crowbar.
- In particular, an object of the invention is to devise a forced entry resistant lock that is much more difficult for a burglar to strip from its seat in the leaf.
- This aim and these and other objects that will become better apparent hereinafter are achieved by a forced entry resistant lock, characterized in that it comprises
- a casing with an opening for one or more engagement elements,
- means for moving said one or more engagement elements from an inactive configuration to a configuration for use, and
- Further characteristics and advantages of the invention will become better apparent from the description of a preferred but not exclusive embodiment of the forced entry resistant lock according to the invention, illustrated by way of non-limiting example in the accompanying drawings, wherein:
-
Figure 1 is a sectional side view of a forced entry resistant lock according to the invention; -
Figure 2 is a sectional top view of the lock ofFigure 1 ; -
Figures 3 and4 are each a side view of a lock according to the invention in a corresponding step of operation, -
Figure 5 is a view of a detail of an engagement element. - With reference to the figures, a forced entry resistant lock according to the invention is generally designated by the
reference numeral 10. - The
lock 10 comprises: - a
casing 15 with anopening 16, for example, for the passage of twoengagement elements - means for moving the
engagement elements - The particularity of the forced entry
resistant lock 10 resides in that it comprises means for fixing to the casing 15 aplate 80 for preventing extraction from the opposite side with respect to theopening 16. - The forced entry

casing 15 then has threadedholes 81 forcorresponding screws 83; thescrews 83 are arranged so as to pass through the extraction-preventingplate 80. - The extraction-preventing
plate 80 in particular is adapted to be mounted in aninterspace 82 between theglazing 14 and theframe 12 of theleaf 13. - The extraction-preventing
plate 80 prevents a burglar from extracting thecasing 15 from itsseat 90, since the dimensions of the extraction-preventingplate 80 prevent its passage through theopening 91 of theseat 90. - The
casing 15 is supported by anouter cover 33 and the extraction-preventingplate 80 is fixed only to thecasing 15 by means of thescrews 83, which pull it, or push it if there is contact, toward thecasing 15. - The extraction-preventing
plate 80 is made of metallic material, but it is to be understood that it can also be made of other similar and equivalent materials. - Therefore it is to be understood that the invention also relates to a
leaf 13 for a door or window assembly of the shutter-like or tilt-and-turn type, of the kind comprising aframe 12 that is arranged so as to surround aglass pane 14 and defines with it aninterspace 82, characterized in that it comprises, within a correspondingflush mounting seat 90, a forced entryresistant lock 10 comprising - a

more engagement elements - and means for fixing to the
casing 15 an extraction-preventingplate 80 on the opposite side with respect to theopening 16, the extraction-preventing 80 plate being arranged in theinterspace 82. - By way of non-limiting example of the invention, the forced entry

engagement elements - means 23 for the translation of the
movable pivot 21 in a direction for the exit of theengagement elements casing 15, in an inactive configuration, toward the outside of thecasing 15, in an intermediate configuration for translation and in a subsequent configuration for use, - means 24 for the rotation in opposite directions of each
engagement element - elastic means 25 for contrasting the rotation of the
engagement elements - The

engagement element engagement element 17, clearly shown inFigure 5 , comprises apivoting portion 26, with athrough hole 27 for themovable pivot 21, and anengagement portion 28, from which thecorresponding engagement tooth 19 protrudes. - A coupling and
rotation tab 30, which extends on the same side as theengagement tooth 19, and an abutment andstroke limiting tab 31 extend radially, in substantially opposite directions, from thepivoting portion 26. - The coupling and
rotation tab 30 has a curved or cam-shaped edge 32 designed to abut against anouter cover 33 of thecasing 15 proximate to theopening 16; such coupling determines the beginning of the rotation of theengagement element 17 during the translation movement of themobile pivot 21, as better described hereinafter. - The abutment and
stroke limiting tab 31 has alinear edge 34 that is adapted to couple to theouter cover 33 on the opposite side proximate to theopening 16 but on the opposite side with respect to the coupling androtation tab 30, so as to stop the rotation of the engagement element that began with the contact of the coupling androtation tab 30 with theouter cover 33. - The

moving body 40 is adapted to be translated in a direction that is perpendicular to thedirection 38 of translation of themovable pivot 21, therefore parallel to theouter edge 36 of theframe 12 of theleaf 13. - The moving
body 40 is provided centrally with a cam-shaped slot 43 in which themovable pivot 21 is arranged so that it can slide. - The cam-
shaped slot 43 comprises twolinear portions intermediate portion 47. - A first
linear portion 45 is extended proximate to theouter cover 33 of thecasing 15. - The second
linear portion 46 is extended proximate to theinner cover 48 of thecasing 15. - The diagonal
intermediate portion 47 is extended between the twolinear portions - The translation of the moving
body 40 causes a thrust, by means of the edges of thediagonal portion 47 of the cam-shaped slot 43, on themovable pivot 21, such as to induce the translation of themovable pivot 21 in thelinear slots 35 of thecasing 15, with consequent translation either toward the outside of thecasing 15 or toward the inside of thecasing 15 of the twoengagement elements Figures 3 and4 . - The moving
