AI Technical Summary
Existing locking devices for closing installations in buildings have a reduced contact surface with the strike plate, limiting mechanical strength and security against break-ins, as the locking member can easily move from an active to an inactive locking position under break-in force.
The locking device incorporates at least two hooking means that can adopt an active hooking position with the locking strike, multiplying contact points and increasing mechanical strength. The displacement drive means drive the hooking means between inactive and active positions, ensuring enhanced security. Reinforcing means are also included to maintain attachment in active positions during break-in attempts.
The enhanced locking device achieves higher mechanical strength and improved security against break-ins, capable of accessing high-level anti-break-in security categories such as RC2, by increasing contact points and maintaining attachment under stress.

Description
Title of the invention: Locking device for an installation for closing an opening in a building
[0001] The invention relates to a locking device which is intended to equip a closing installation which is configured to close an opening which a construction comprises.
[0002] This invention relates to the field of building hardware, more particularly the field of locking devices which are configured to ensure the locking, in the closed position, of an installation for closing an opening that a construction has. These locking devices are, more particularly, configured to equip such a closing installation, more particularly an opening and a frame that such a closing installation comprises.
[0003] Locking devices are already known which comprise, on the one hand, a strike plate which equips the frame with a closing installation and, on the other hand, a locking system, which equips the opening with this closing installation, and which is actuated by a locking rod usually controlled by a handle or the like. Such a locking system usually comprises a locking member which adopts the form of a roller or a hook, and which is movable between, on the one hand, an inactive locking position in which this locking member does not cooperate with the strike plate and, on the other hand, an active locking position in which this locking member cooperates with the strike plate. It will be observed that such a locking member has a reduced contact surface with the strike plate which limits the mechanical strength of the locking device, in particular in the event of an attempted break-in.Furthermore, a break-in force exerted on the closing installation and / or on the locking device may result in the locking member moving from an active locking position to an inactive locking position. As a result, these locking devices cannot guarantee a high level of security against break-in.
[0004] The present invention aims to remedy the drawbacks of the locking devices of the state of the art.
[0005] For this purpose, the invention relates to a locking device for an installation for closing an opening of a building. Such a locking device comprises a locking strike which is configured to equip a frame, respectively an opening, of the closing installation. Such a locking device also comprises a locking system, which is configured to equip the opening, respectively the frame, of the closing installation, and which is configured to cooperate with the locking strike. This locking system comprises, on the one hand, a housing which is configured to equip the opening, respectively the frame, on the other hand, at least one locking rod, which is configured to equip the opening, respectively the frame, and which is movable relative to the housing, on the other hand also, at least two hooking means, which are movable relative to the housing, and which are configured to adopt an inactive position of hooking said at least two hooking means with the locking strike and an active position of hooking said at least two hooking means with the locking strike, on the other hand again, displacement mounting means which are configured to mount said at least two hooking means in displacement relative to the housing,this between the inactive hooking position and the active hooking position of said at least two hooking means with the locking latch and, on the other hand also, displacement drive means which are configured to drive said at least two hooking means in displacement, as the case may be, in the direction of the inactive hooking position or in the direction of the active hooking position, this under the impulse of the displacement of the locking rod.
[0006] According to another characteristic, said at least two attachment means each adopt the form of a attachment hook and each comprise a attachment member while the attachment members of said at least two attachment means are oriented towards each other and / or face each other.
[0007] An additional feature concerns the fact that the displacement mounting means are configured to mount said at least two attachment means in translation relative to the housing, this in the same direction which is parallel to the direction of displacement of the locking rod.
[0008] Alternatively, the displacement mounting means are configured to mount, relative to the housing, on the one hand, at least one of said at least two attachment means in rotation about a first axis of rotation and, on the other hand, at least one other of said at least two attachment means in rotation about a second axis of rotation which is parallel to the first axis of rotation.
[0009] Yet another characteristic, the movement drive means are configured to drive said at least two attachment means towards and away from at least one of said at least two attachment means from at least one other of said at least two attachment means.
[0010] According to another characteristic, the means for driving the movement of said at least two attachment means comprise, on the one hand, primary means for driving the movement which are configured to drive at least one of said at least two attachment means in a first direction of movement. placement and, on the other hand, secondary movement drive means which are configured to drive at least one other of said at least two attachment means in movement in a second direction of movement which is the opposite of the first direction of movement.
[0011] Another characteristic relates to the fact that the means for driving said at least two attachment means in movement comprise means for driving said at least two attachment means in translation. However, and alternatively, the means for driving said at least two attachment means in movement comprise means for driving said at least two attachment means in rotation.
[0012] Yet another characteristic relates to the fact that the locking device comprises reinforcing means which are configured to reinforce the attachment of at least one of said at least two attachment means on the locking striker, this in the active attachment position and in the event of break-in stress exerted on the locking device and / or on the closing installation.
[0013] According to another characteristic, the locking device comprises means for holding at least one of said at least two hooking means in the inactive hooking position of said at least two hooking means.
[0014] Yet another characteristic concerns the fact that the locking device comprises means for fixing the locking system to the opening, respectively to the frame. These fixing means comprise, on the one hand, at least one plate which is configured to bear on the rear of an internal wall that the opening, respectively the frame, comprises, and / or to come to be positioned inside a rebate that the opening, respectively the frame, comprises, and, on the other hand, at least one fixing member which is configured to cooperate with said at least one plate as well as with a headrest that the locking system and / or the closing installation comprises.
[0015] Thus, the locking device of the invention comprises at least two hooking means which can adopt an active hooking position with the locking strike. The presence of these at least two hooking means makes it possible to multiply the points of contact between the locking strike and the locking system in the active hooking position, which advantageously makes it possible to increase the mechanical strength of the locking device, in particular in the event of an attempted break-in, and thus to improve the locking. The improvement of this locking then allows the locking device of the invention to access high-level anti-break-in security categories, in particular level RC2.
[0016] Furthermore, in the locking device, the displacement drive means are configured to drive said at least two displacements means for hooking at least one of said at least two hooking means towards and away from at least one other of said at least two hooking means. These hooking means then operate in opposition of movement so that, when at least one of these hooking means is requested to be unhooked from the latch (in particular in the context of an attempted break-in), at least one other of these hooking means reinforces its hooking on the latch. This results in improved locking.
[0017] Furthermore, the locking device comprises reinforcing means which are configured to reinforce the attachment of said at least two attachment means to the locking striker. Such reinforcing means advantageously allow, in the event of a break-in force exerted on the locking device, to bring at least one of said at least two attachment means into an active reinforced attachment position (going beyond the active attachment position). Such reinforcing means are configured so that only an action on the locking rod allows said at least two attachment means to be brought into their inactive attachment position.
[0018] Finally, the locking device comprises means for fixing the locking system to the opening, respectively to the frame. Such fixing means advantageously make it possible to reinforce the connection between the locking system and the opening, respectively the frame, of the closing installation.

[0031] With reference in particular to the aforementioned figures, the present invention relates to the field of building hardware, more particularly the field of locking devices which are configured to ensure the locking, in the closed position, of an installation for closing an opening of a construction.
[0032] Such a closing installation may consist of a window, a French window, a bay window or other.
[0033] Such a closing installation I comprises, on the one hand, at least one frame D which is made integral with the masonry, which delimits said opening, and which the construction comprises and, on the other hand, at least one opening O which is movable relative to the frame D, this between an open position ([Fig.l]) and a closed position.

In fact, such a locking system 3 is, more particularly, configured to be installed, at least in part, inside a housing that this opening O, respectively this frame D, comprises, more particularly at the interior of a housing which includes one of the profiles which this opening O, respectively this fixed frame D, includes.
[0037] Such a locking system 3 is also configured to cooperate with the locking latch 2.
[0038] Said locking system 3 comprises a housing 4 which is configured to equip the opening O, respectively the frame D. In fact, this housing 4 is, more particularly, configured to be installed, at least in part, inside the aforementioned housing that this opening O, respectively this frame D comprises, more particularly inside the aforementioned housing that comprises one of the profiles that comprise this opening O, respectively this frame D.

This locking rod 5 is configured to cooperate (directly or indirectly) with a control member, more particularly in the form of a handle or the like, which equips the opening O, respectively the frame D.
[0040] Said locking system 3 also comprises at least two attachment means (6; 6'), each of which adopts the form of an attachment hook, and each of which comprises a attachment member (60; 60'). The attachment members (60; 60') of said at least two attachment means (6; 6') are oriented towards one (60; 60') of the other (60'; 60) and / or face each other.
[0041] Furthermore, said at least two attachment means (6; 6') each comprise, on the one hand, an internal part which extends inside the housing 4 and, on the other hand, an external part, which extends outside the housing 4, and which comprises said attachment member (60'; 60).
[0042] Said at least two hooking means (6; 6') are movable relative to the housing 4 and are configured to adopt, on the one hand, an inactive position of hooking of said at least two hooking means (6; 6') with the locking catch 2 (figures 3, 5 and 8) in which said at least two hooking means (6; 6') (more particularly the hooking members 60; 60') are not hooked to the locking catch 2.
[0043] On the other hand, said at least two hooking means (6; 6') are configured to adopt an active position of hooking of said at least two hooking means (6; 6') with the locking catch 2 (figures 2, 4, 6 and 9) in which said at least two hooking means (6; 6') (more particularly the hooking members 60; 60') are hooked to the locking catch 2.
[0044] In this regard, it will be observed that this locking latch 2 then comprises, at at least two complementary attachment means (20; 20), on the one hand, which are configured to be fixed relative to the frame D, respectively relative to the opening O, and, on the other hand, which are each configured to cooperate with one (6; 6') of said at least two attachment means (6; 6'), more particularly with one (60; 60') of the attachment members (60; 60') that said at least two attachment means (6; 6') comprise, this in the active attachment position.
[0045] Said locking system 3 further comprises displacement mounting means 7 which are configured to mount said at least two hooking means (6; 6') in displacement relative to the housing 4, this between the inactive hooking position and the active hooking position of said at least two hooking means (6; 6') with the locking striker 2.

[0047] According to a second type of embodiment (illustrated in figures 5 to 10), the displacement mounting means 7 are configured to mount, relative to the housing 4, on the one hand, at least one 6 of said at least two attachment means (6; 6') in rotation around a first axis of rotation XI and, on the other hand, at least one other 6' of said at least two attachment means (6; 6') in rotation around a second axis of rotation X2 which is parallel to the first axis of rotation XL
[0048] In this regard, it will be observed that the first axis of rotation XI and the second axis of rotation X2 are perpendicular to the direction of movement of the locking rod 5.
[0049] Yet another characteristic concerns the fact that said locking system 3 also comprises movement drive means 8 which are configured to drive said at least two hooking means (6; 6') in movement, as the case may be, in the direction of the inactive hooking position (more particularly from the active hooking position) or in the direction of the active hooking position (more particularly from the inactive hooking position), this under the impulse of the movement of the locking rod 5.

[0066] According to another characteristic, the locking device 1 comprises reinforcing means 11 which are configured to reinforce the attachment of at least one (6; 6') of said at least two attachment means (6; 6') on the locking strike 2, this in the active attachment position of said at least two attachment means (6; 6') and in the event of break-in stress exerted on the locking device 1 and / or on the closing installation I.
[0067] As can be seen in particular in Figures 8 to 10, the reinforcing means 11 comprise at least one housing 110, which the easel 910 comprises (more particularly which the primary rotational drive means 91 comprise), which extends from (more particularly in the extension) of said at least one guide light 911 (which the easel 910 comprises) as well as in a direction which forms a non-zero angle (preferably open or obtuse) with the direction in which said at least one guide light 911 extends (direction which then also forms a non-zero angle with the direction of movement of the locking rod 5), and inside which said guide member 912 is housed, this in the active position of attachment of said at least two attachment means (6;6') and in the event of a break-in force exerted on the locking device 1 and / or on the closing installation I, more particularly a traction exerted perpendicular to the direction of movement of the locking rod 5 on at least one (6; 6') of said at least two hooking means (6; 6'). ;
[0068] Additionally, such reinforcing means 11 may also comprise at least one other housing (not shown), which is comprised by the easel 1010 (more particularly which is comprised by the secondary rotational drive means 101), which extends from (more particularly in the extension) of said at least one guide light 1011 (which is comprised by the easel 1010) as well as in a direction which forms a non-zero angle (preferably open or obtuse) with the direction in which said at least one guide light 1011 extends (direction which then also forms a non-zero angle with the direction of movement of the locking rod 5), and inside which said guide member 1012 is housed, this in the active hooking position of said at least two hooking means (6; 6') and in the event of a break-in force exerted on the locking device 1 and / or on the closing installation I, more particularly of a traction exerted perpendicular to the direction of movement of the locking rod 5 on at least one (6; 6') of said at least two hooking means (6; 6').
[0069] Yet another feature concerns the fact that the locking device 1 comprises holding means 12 which are configured to hold at least one (6; 6') of said at least two hooking means (6; 6') in the inactive hooking position of said at least two hooking means (6; 6').
[0070] As can be seen in particular in Figures 5 to 7, these holding means 12 comprise at least one housing 120, which the easel 910 comprises (more particularly which the primary rotational drive means 91 comprise), which extends from (more particularly in the extension) of said at least one guide light 911 (which the easel 910 comprises) as well as in a direction which forms a non-zero angle (preferably open or obtuse) with the direction in which said at least one guide light 911 extends (direction which then also forms a non-zero angle with the direction of movement of the locking rod 5), and inside which said guide member 912 is housed, this in the inactive position of attachment of said at least two attachment means (6; 6').
[0071] Additionally, these holding means 12 may also comprise at least one other housing 121, which the easel 1010 comprises (more particularly which the secondary rotational drive means 101 comprise), which extends from (more particularly in the extension) of said at least one guide light 1011 (which the easel 1010 comprises) as well as in a direction which forms a non-zero angle (preferably open or obtuse) with the direction in which said at least one guide light 1011 extends (direction which then also forms a non-zero angle with the direction of movement of the locking rod 5), and inside which said guide member 1012 is housed, this in the inactive position of attachment of said at least two attachment means (6; 6').
