Description

[0001] The invention relates to an electric strike, more particularly an electric strike with memory, or even with emission.

[0002] The present invention relates to the field of hardware and, more particularly, to the manufacture of security systems which are designed to lock, respectively unlock, an opening to prevent, respectively authorize, access to a place, in particular to a building.

[0003] Electric latches are already known which comprise at least one locking means, which is configured to lock an opening, and which can adopt an active locking position and an inactive locking position for such an opening.

[0004] Such an electric strike can be of different types.

[0005] A first type relates to a current-breaking electric strike which is designed so that, as long as the electric strike is supplied with electric current, the locking means adopts an active locking position in which the opening is locked and cannot be actuated. In the absence of electric current supply to the electric strike, the locking means can then adopt an inactive locking position in which the opening is unlocked and can be actuated.

[0006] A second type relates to a current-release electric strike which is designed so that, as long as the electric strike is not supplied with electric current, the locking means adopts an active locking position and the opening cannot be actuated. When the electric strike is supplied with electric current and as long as this electric strike is supplied with electric current, the locking means can adopt an inactive locking position in which the opening is unlocked and can be actuated.

[0007] We also know a mixed electric strike that operates on current failure as well as on current emission. Such an electric strike includes a member which, depending on its position within the electric strike, allows this electric strike to be configured, as the case may be, on current failure or on current emission. The transition from an electric strike with current failure to an electric strike with current emission (and vice versa) requires the dismantling of the electric strike, the removal of said member, the modification of the positioning of this member, the replacement of this member within the strike and the reassembly of this strike, which results in long and tedious operations.

[0008] A third type relates to an electric strike with memory which is designed so that, as long as the electric strike is not supplied with electric current, the locking means adopts an active locking position, is immobilized in its active locking position, and the opening cannot be actuated. When the electric strike is supplied with electric current, the locking means is no longer immobilized in the active locking position and can adopt an inactive locking position, this as long as the locking means is not brought into the inactive locking position by the opening and even after interruption of the electric current supply to the electric strike.After the locking means has been brought into the inactive locking position by actuation of the opening leaf and after this locking means has returned to its active locking position, this locking means again adopts an active locking position, is immobilized in this active locking position, and the opening leaf cannot be actuated.

[0009] Such a memory electric strike has many components, which complicates the design of such an electric strike. In addition, these components are small, which weakens such an electric strike. In addition, these many components are mobile, which increases the risk of failure of the electric strike. Finally, such a memory electric strike cannot operate like a conventional current-release strike and vice versa.

[0010] The present invention aims to remedy the drawbacks of electric strikes of the state of the art.

[0011] To this end, the invention relates to an electric strike which comprises: a housing; a locking means, which is configured to lock an opening relative to a frame, and which is movable between an active position for locking an opening and an inactive position for locking the opening; an immobilization means, which is configured to immobilize said locking means which is in the active position for locking the opening, and which is movable between an active position for immobilizing the locking means and an inactive position for immobilizing the locking means; a blocking means, which is configured to block the immobilization means which is in the active position for immobilizing the locking means, and which is movable between an active position for blocking the immobilization means and an inactive position for blocking the immobilization means;a drive means which is configured to drive the locking means from the active locking position of the immobilizing means to the inactive locking position of the immobilizing means; a holding means, which is configured to hold the locking means in the inactive locking position of the immobilizing means, and which is movable between an active holding position of the locking means and an inactive holding position of the locking means.

[0012] In this electric strike, the locking means is movable in translation along a translation axis and comprises a carriage which cooperates with the immobilization means.

[0013] According to another characteristic, the electric strike comprises a control means which is configured to control the passage of the holding means from the active holding position of the blocking means to the inactive holding position of the blocking means, this under the impulse of the movement of the immobilization means.

[0014] Yet another feature is that the electric strike includes an inhibiting means which is configured to inhibit the holding means.

[0015] According to an additional feature, the electric strike comprises an activation means which is configured to activate the inhibition means while the electric strike is configured so that this activation means is accessible from outside the housing.

[0016] Thus, the electric strike according to the invention comprises a limited number of components which advantageously makes it possible to simplify the design of this electric strike, to stiffen the components by increasing their size, and thus to increase the reliability of such an electric strike compared to those of the state of the art.

[0017] In addition, the components of such an electric strike are advantageously designed and arranged to enable this electric strike to operate as an electric strike with memory. In addition, this electric strike comprises an inhibition means which is configured to inhibit the holding means which advantageously enables this electric strike to operate as an electric strike with current emission.

[0018] This electric strike also comprises an activation means, which is configured to activate the inhibition means, and which then advantageously makes it possible to select the operation of the electric strike either as an electric strike with memory, or as an electric strike with current emission. Such activation is advantageously possible from outside the housing and without dismantling the electric strike.

[0019] Other aims and advantages of the present invention will appear during the description which follows relating to embodiments which are given only as indicative and non-limiting examples.

[0020] Understanding of this description will be facilitated by referring to the attached drawings in which: [ Fig 1 ] is a schematic, perspective and exploded view of an electric strike according to the invention.

[0021] With particular reference to the above-mentioned figures, the present invention relates to the field of hardware and, more particularly, to the manufacture of security systems which are designed to lock, respectively unlock, an opening to prevent, respectively authorize, access to a place, in particular to a building.

[0022] The invention then relates to an electric strike 1 which is intended to equip a frame, which comprises a construction, and which delimits an opening. Such an electric strike 1 can be positioned at least partly inside a housing which comprises this frame.

[0023] Such an electric strike 1 is configured to cooperate with an opening, which closes said opening, and which is mounted in movement (in particular in rotation) on said frame. Such an electric strike 1 can, then, cooperate with a bolt that comprises a lock that equips such an opening.

[0024] Such an electric strike 1 comprises a housing 2 which equips said frame, in particular by being positioned at least partly inside a housing which this frame comprises.

[0025] Such an electric strike 1 comprises a locking means 3 which is configured to lock said opening relative to said frame. It is, more particularly, this locking means 3 which then cooperates with the bolt of the lock which equips said opening.

[0026] Such a locking means 3 is movable between an active position for locking an opening ( figures 2 to 7 And 12 à 14 ) and an inactive opening locking position ( figures 8 to 11 ).

[0027] Such a locking means 3 is movable in rotation around an axis of rotation Xr3, this between the active position and the inactive locking position.

[0028] Alternatively or (and preferably) additionally, such locking means 3 may comprise a trigger or a half-turn.

[0029] The electric strike 1 also comprises a return means 4 for returning the locking means 3 which is configured to drive the locking means 3 from the inactive locking position of the opening to the active locking position of the opening, this in rotation around the axis of rotation Xr3. Such a return means 4 may take the form of a torsion spring, in particular a helical spring.

[0030] Said electric strike 1 further comprises an immobilization means 5 which is configured to immobilize said locking means 3 which is in the active position for locking the opening.

[0031] This immobilization means 5 is movable between, on the one hand, an active position for immobilizing the locking means 3 (more particularly which is in the active position for locking the opening) and, on the other hand, an inactive position for immobilizing the locking means 3 (more particularly which is in the active or inactive position for locking the opening).

[0032] Such an immobilization means 5 is movable in translation along a translation axis Xt5 which can be perpendicular to the rotation axis Xr3.

[0033] Alternatively or (and preferably) additionally, such an immobilization means 5 may comprise a lateral immobilization finger 50 which cooperates with the locking means 3.

[0034] Such a lateral immobilizing finger 50 can extend in a direction parallel to the axis of rotation Xr3.

[0035] The electric strike 1 also comprises a return means 6 for the immobilization means 5 which is configured to drive the immobilization means 5 from the inactive immobilization position of the locking means 3 to the active immobilization position of the locking means 3, this in translation along the translation axis Xt5. Such a return means 6 can adopt the form of a compression spring, in particular a helical spring.

[0036] The electric strike 1 further comprises a blocking means 7 which is configured to block the immobilization means 5 which is in the active immobilization position of the locking means 3 (more particularly which is in the active locking position of the opening).

[0037] Such a blocking means 7 is movable between, on the one hand, an active blocking position of the immobilization means 5 (more particularly which is in the active immobilization position of the locking means 3 which is in the active locking position of the opening) and, on the other hand, an inactive blocking position of the immobilization means 5 (more particularly which is in the active or inactive immobilization position of the locking means 3 which is in the active or inactive locking position of the opening).

[0038] Such a locking means 7 is movable in translation along a translation axis Xt7 which can be parallel to the rotation axis Xr3 and / or perpendicular to the translation axis Xt5.

[0039] Alternatively or (and preferably) additionally, such a blocking means 7 comprises a carriage 70 which cooperates with the immobilization means 7. This carriage 70 is then movable in translation along the translation axis Xt7

[0040] According to another characteristic, the locking means 7 (more particularly the carriage 70) comprises, on the one hand, a bearing surface 71 against which the immobilization means 5 bears (more particularly which is in the active position of immobilization of the locking means 3) this in the active position of blocking of this immobilization means 5 by the locking means 7 and, on the other hand, a housing 72, which adjoins and / or which extends the bearing surface 71, and inside which the immobilization means 5 engages (more particularly which is in the active or inactive position of immobilization of the locking means 3) this in the inactive position of blocking of this immobilization means 5 by the locking means 7.

[0041] The electric strike 1 further comprises a drive means 8 which is configured to drive the locking means 7 from the active locking position of the immobilization means 5 (more particularly which is in the active immobilization position of the locking means 3) to the inactive locking position of the immobilization means 5 (more particularly which is in the active or inactive immobilization position of the locking means 3).

[0042] In fact, this drive means 8 is configured to drive the locking means 7 from the active locking position to the inactive locking position of the immobilization means 5, this under the impulse of an electric current supply to the electric strike 1, more particularly to this drive means 8.

[0043] Such a drive means 8 may comprise an electromagnet 80 which comprises a solenoid which extends along an axis which is parallel to the rotation axis Xr3 and / or which is at least parallel to (or even coincident with) the translation axis Xt7 along which the locking means 7 is movable in translation.

[0044] The electric strike 1 also comprises a return means 9 for the blocking means 7 which is configured to drive the blocking means 7 from the inactive blocking position of the immobilization means 5 to the active blocking position of the immobilization means 5, more particularly against the action of the drive means 8.

[0045] Such a return means 9 may take the form of a compression spring, in particular a helical spring.

[0046] The electric strike 1 also comprises a holding means 10 which is configured to hold the blocking means 7 in the inactive blocking position of the immobilization means 5.

[0047] Such a holding means 10 is movable between, on the one hand, an active holding position of the blocking means 7 (more particularly which is in the inactive blocking position of the immobilization means 5) and, on the other hand, an inactive holding position of the blocking means 7 (more particularly which is in the active or inactive blocking position).

[0048] In fact, such a holding means 10 is configured to hold the blocking means 7 in the inactive blocking position of the immobilization means 5, this against the action of the return means 9 of the blocking means 7.

[0049] Such a holding means 10 comprises, on the one hand, a holding member 100 which is deformable and / or which is movable and, on the other hand, a holding finger 101, which cooperates with the blocking means 7, and which extends laterally relative to the holding member 100 as well as from this holding member 100. Such a holding finger 101 may consist of a cutout and / or a deformation of an element which also comprises the holding member 100.

[0050] According to a first embodiment illustrated in the figures 1 to 14 in the appendix, said holding member 100 comprises (or is constituted by) at least one blade 102 which is deformable and / or which is movable in rotation around an axis of rotation Xr10 (which can be parallel to the axis of rotation Xr3 and / or to the axis of translation Xt7).

[0051] The holding finger 101, which such a holding member 100 comprises, then extends laterally relative to the blade 102 and from this blade 102.

[0052] At least one part of such a holding means 10 (more particularly said at least one blade 102 and said holding finger 101) may be constituted by a folded sheet metal.

[0053] According to a second embodiment illustrated in the figures 15 to 17 in the appendix, said holding member 100 comprises (or is constituted by) at least one stud 103 which is movable in translation along a translation axis Xt10 (which can extend in a direction which can be parallel to the translation axis Xt5 and / or perpendicular to the rotation axis Xr3 and / or perpendicular to the translation axis Xt7) while the holding finger 101 extends laterally relative to the stud 103 and from this stud 103.

[0054] Such a pad 103 may adopt the shape of a tube and have a housing (in particular through) inside which is positioned a fixed shaft, which extends along said translation axis Xt10, and relative to which said pad 103 is movable in translation.

[0055] According to another characteristic, the locking means 7 comprises a bearing surface 73 against which the holding means 10 (more particularly the holding finger 101) bears, this in the active position of holding the locking means 7 (by the holding means 10) in the inactive position of locking the immobilization means 5 (by the locking means 7).

[0056] Yet another feature is that the electric strike 1 includes a return means 11 for the holding means 10 which is configured to drive the holding means 10 from the inactive holding position of the blocking means 7 to the active holding position of the blocking means 7.

[0057] Such a return means 11 may be constituted by the blade 102 itself which may then be of the elastic type and / or by a torsion spring (in particular helical and / or which acts on such a blade 102) and / or by a compression spring (in particular which acts on said stud 103).

[0058] The electric strike 1 also comprises a control means 12 which is configured to control the passage of the holding means 10 from the active holding position of the blocking means 7 (more particularly which is in the inactive blocking position of the immobilization means 5) to the inactive holding position of the blocking means 7.

[0059] This control means 12 can be configured to exert such a control against the action of the return means 11.

[0060] It will be observed that it is, more particularly, the immobilization means 5 which comprises such a control means 12.

[0061] This control means 12 may comprise a lateral control finger 120 which extends in a direction perpendicular to the rotation axis Xr3 and perpendicular to the translation axis Xt5 of the immobilization means 5.

[0062] This immobilization means 5 can then comprise, on the one hand, the aforementioned lateral immobilization finger 50 and, on the other hand, the aforementioned lateral control finger 120.

[0063] Said control means 12 is configured to control the holding means 10 under the impulse of the movement of the immobilization means 5 (more particularly from the active immobilization position of the locking means 3 to the inactive immobilization position of this locking means 3), this under the impulse of the movement of the locking means 3 (more particularly from the active locking position of the opening to the inactive locking position of the opening), in particular under the impulse of an actuation of this opening.

[0064] Yet another feature concerns the fact that the electric strike 1 comprises an inhibition means 13 which is configured to inhibit the holding means 10. This inhibition means 13 then prevents the operation of this holding means 10 so that the blocking means 7 can no longer be held in the inactive blocking position of the immobilization means 5 by this holding means 10.

[0065] In this regard, it will be observed that this inhibition means 13 can then adopt, on the one hand, an active position of inhibition of the holding means 10. In this active inhibition position, the holding means 10 cannot maintain the blocking means 7 in the inactive blocking position of the locking means 5 and this blocking means 7 is then only subject to the action of the drive means 8 and to the action of the return means 9. The electric strike 1 then adopts the operation of a current-emitting electric strike.

[0066] On the other hand, this inhibition means 13 can adopt an inactive position of inhibition of the holding means 10. In this position, the holding means 10 can maintain the blocking means 7 in its inactive position of blocking the immobilization means 5. The electric strike 1 then adopts the operation of an electric strike with memory.

[0067] According to the first embodiment illustrated figures 1 to 14 , this inhibition means 13 is movable in rotation around an axis of rotation which is parallel to the axis of rotation Xr3 of the locking means 3 and / or at least parallel to (or even, and preferably, coincident with) the axis of rotation Xr10 of the holding member 100. This inhibition means 13 is, then, movable in rotation around this axis of rotation, this between the inactive position ( figures 2 to 11 ) and the active position ( figures 12 to 14 ) of inhibition of the holding means 10.

[0068] In fact, the inhibition means 13 comprises a positioning means 14 which is configured to position and maintain the holding means 10 in its inactive position for maintaining the blocking means 7.

[0069] Such a positioning means 14 is, here again, movable in rotation around an axis of rotation which is parallel to the axis of rotation Xr3 of the locking means 3 and / or at least parallel to (or even, and preferably, coincident with) the axis of rotation Xr10 of the holding member 100. This positioning means 14 is, then, movable in rotation around this axis of rotation, this between an inactive position ( figures 2 to 11 ) and an active position ( figures 12 to 14 ) for maintaining the holding means 10 in its inactive position for maintaining the blocking means 7.

[0070] Such a positioning means 14 comprises, on the one hand, a ring 140 which is movable in rotation around an axis of rotation, more particularly which is parallel to the axis of rotation Xr3 of the locking means 3 and / or at least parallel to (or even, and preferably, coincident with) the axis of rotation Xr10 of the holding member 10 and, on the other hand, a positioning finger 141, which cooperates with the holding means 10 (more particularly with a free end, which the holding member 100 comprises, and which is opposite an end of the holding member 100 from which the holding finger 101 extends, figures 12 And 13 ), and which extends laterally relative to the ring 140 and from this ring 140.

[0071] According to the second embodiment illustrated figures 15 to 17, the inhibition means 13 is movable in translation along a translation axis which is parallel to the translation axis Xt5 of the immobilization means 5 and / or at least parallel to (or even, and preferably, coincident with) the translation axis Xt10 of the holding member 100. This inhibition means 13 is, then, movable in translation along this translation axis, this between the inactive position ( figures 15 And 16 ) and the active position ( Figure 17 ) of inhibition of the holding means 10.

[0072] In fact, the inhibition means 13 again comprises a positioning means 14 which is configured to position and maintain the holding means 10 in its inactive position for maintaining the blocking means 7.

[0073] Such a positioning means 14 is, here again, movable in translation along a translation axis which is parallel to the translation axis Xt5 of the immobilization means 5 and / or at least parallel to (or even, and preferably, coincident with) the translation axis Xt10 of the holding member 100. This positioning means 14 is, then, movable in translation along this translation axis, this between an inactive position ( figures 15 And 16 ) and an active position ( Figure 17 ) for maintaining the holding means 10 in its inactive position for maintaining the blocking means 7.

[0074] Such a positioning means 14 comprises, here again, a ring which is movable in translation along a translation axis, more particularly which is parallel to the translation axis Xt5 of the immobilization means 5 and / or at least parallel to (or even, and preferably, coincident with) the translation axis Xt10 of the holding member 100. This ring then cooperates with the holding means 10, in particular with the holding member 100, more particularly with one end, which the holding member 100 comprises, and which is opposite one end of the holding member 100 from which the holding finger 101 extends. Said ring can then be positioned around the fixed shaft, which extends along said translation axis Xt10, and relative to which said stud 103 is movable in translation and also be movable in translation relative to this fixed shaft.

[0075] Yet another characteristic concerns the fact that the electric strike 1 comprises an activation means 15 which is configured to activate the inhibition means 13, more particularly to make this inhibition means 13 adopt an active position of inhibition of the holding means 10 and an inactive position of inhibition of this holding means 10.

[0076] The electric strike 1 is configured so that the activation means 15 is accessible from outside the housing 2, more particularly without dismantling this housing 2.

[0077] Such an activation means 15 may take the form of a screw or the like which is engaged with the aforementioned ring 140 or, again, the form of a member (in particular an imprint or the like) which this ring 140 comprises and which is capable of receiving an actuating tool (such as a screwdriver).

[0078] Finally, the electric strike 1 may also comprise a locking means 16 which is configured to lock the inhibition means 13 (more particularly in its active or inactive inhibition position) and / or the activation means 15 of this inhibition means 13.

[0079] Again, such locking means 16 may comprise a screw.

[0080] The electric strike 1 is configured so that the locking means 16 is accessible from outside the housing 2, more particularly without dismantling this housing 2.

[0081] In this regard, it will be observed that this housing 2 comprises, internally, at least a part of the locking means 3, at least a part (or even the entirety) of the immobilization means 5, at least a part (or even the entirety) of the blocking means 7, at least a part (or even the entirety) of the drive means 8, at least a part (or even the entirety) of the holding means 10, at least a part (or even the entirety) of the control means 12 and at least a part (or even the entirety) of the inhibition means 13.

[0082] This housing 2 then also comprises, internally, at least part (or even all) of the return means (4, 6, 9, 11).

[0083] In the remainder of the description, the operation of the electric strike 1 according to the invention will be described.

[0084] As mentioned above, when the inhibiting means 13 adopts an inactive position of inhibiting the holding means 10 ( figures 2 to 11), this holding means 10 can adopt an active position for holding the blocking means 7 and the electric strike 1 can adopt the operation of an electric strike with memory.

[0085] In the absence of a power supply to the electric strike 1 with electric current, the locking means 3 is in the active position for locking the opening, the immobilization means 5 is in the active position for immobilizing the locking means 3, the blocking means 7 is in the active position for blocking the immobilization means 5 and the holding means 10 is in the inactive position for holding the blocking means 7 ( figures 2 to 4 ).

[0086] When an unlocking command is given to the electric strike 1, an electric current supplies the drive means 8 which drives the locking means 7 from the active locking position of the immobilization means 5 to the inactive locking position of the immobilization means 5. The holding means 10 moves from the inactive holding position of the locking means 7 to the active holding position of the locking means 7 (in the inactive locking position of the immobilization means 5), in particular under the effect of the return means 11. This locking means 7 is held in the inactive locking position of the immobilization means 5 by the holding means 10. This immobilization means 5 is then free to move from the active immobilization position of the locking means 3 to the inactive immobilization position of the locking means 3.This locking means 3 is free to move from the active locking position of the opening to the inactive locking position of the opening, in particular under the impulse of the actuation of this opening. figures 5 to 7 ).

[0087] This configuration is maintained as long as the opening is not activated.

[0088] When the opening is actuated, the locking means 3 moves from the active locking position of the opening to the inactive locking position of the opening. This locking means 3 then drives the immobilization means 5 which moves from the active immobilization position of the locking means 3 to the inactive immobilization position of the locking means 3. Under the effect of the movement of the immobilization means 5, the control means 12 (which this immobilization means 5 comprises) controls the holding means 10 which moves from the active holding position of the blocking means 7 to the inactive holding position of the blocking means 7. Under the effect of the return means 9, the blocking means 7 moves from the inactive blocking position of the immobilization means 5 towards the active blocking position of the immobilization means 5 ( figures 8 to 11 ).

[0089] After actuation of the opening, the locking means 3 passes from the inactive locking position of the opening to the active locking position of the opening, this under the effect of the return means 4. The immobilization means 5 then passes from the inactive immobilization position of the locking means 3 to the active immobilization position of the locking means 3, this under the effect of the return means 6. The blocking means 7 passes from the inactive blocking position of the immobilization means 5 to the active blocking position of the immobilization means 5, this under the effect of the return means 9.

[0090] As mentioned above, when the inhibiting means 13 adopts an active position of inhibiting the holding means 10 ( figures 12 to 14 ), this holding means 10 adopts an inactive position for holding the blocking means 7 and the electric strike 1 can adopt the operation of a current-emitting electric strike.

[0091] In the absence of a power supply to the electric strike 1 with electric current, the locking means 3 is in the active position for locking the opening, the immobilization means 5 is in the active position for immobilizing the locking means 3, the blocking means 7 is in the active position for blocking the immobilization means 5 ( figures 12 to 14 ).

[0092] When an unlocking command is given to the electric strike 1, an electric current supplies the drive means 8 which drives the locking means 7 from the active locking position of the immobilization means 5 to the inactive locking position of the immobilization means 5. The immobilization means 5 is then free to move from the active immobilization position of the locking means 3 to the inactive immobilization position of the locking means 3. This locking means 3 is free to move from the active locking position of the opening leaf to the inactive locking position of the opening leaf, in particular under the impulse of the actuation of this opening leaf.

[0093] This configuration is maintained as long as the electric strike is supplied with electrical current.

[0094] When the opening leaf is actuated, the locking means 3 moves from the active locking position of the opening leaf to the inactive locking position of the opening leaf. This locking means 3 then drives the immobilization means 5 which moves from the active immobilization position of the locking means 3 to the inactive immobilization position of the locking means 3. After the opening leaf is actuated, the locking means 3 moves from the inactive locking position of the opening leaf to the active locking position of the opening leaf, this under the effect of the return means 4. The immobilization means 5 then moves from the inactive immobilization position of the locking means 3 to the active immobilization position of the locking means 3, this under the effect of the return means 6.When the electric current supply to the electric strike 1 is interrupted, the blocking means 7 moves from the inactive blocking position of the immobilization means 5 to the active blocking position of the immobilization means 5, this under the effect of the return means 9.
