Description

2888601 1

  The invention relates to a device for locking a movable leaf.

  The locking device applies in particular to a gate with two leaves, one of the wings is a pivoting flap supporting a bolt.

  Document FR 2 697 278 A1 describes a device for locking a double-leaf gate. The device is intended to be fixed on a leaf, in front of a lock fixed on the other leaf, the lock having bolts. The locking device comprises a movable anchor rod, a sliding striker adapted to receive the bolts and a transmission element. A displacement of the transmission element causes both the displacement of the rod and the movement of the striker.

  A disadvantage of this type of device is that it is adapted to lock a flap opening by pivoting in a given direction of rotation.

  The same device can not be used to lock a leaf opening by pivoting in the opposite direction.

  Therefore, it is necessary to provide several types of locking devices adapted to several types of leaves.

  In addition, it is not always easy for a user to determine which locking device is suitable for the type of gate on which he wishes to install the locking device.

  An object of the invention is to provide a device for locking a movable leaf which is suitable for several types of leaf.

  This problem is solved in the context of the present invention by means of a locking device of a movable wing comprising: - a piece of striker adapted to receive a bolt mounted on the wing, - a coupling piece comprising a cam surface fit converting an actuating movement generated in a first direction into a movement of the striker piece in a second direction between a locked position in which the striker piece 2888601 2 receives the bolt and an unlocked position in which the striker piece releases the bolt, the strike piece and the coupling piece being formed in two separate pieces.

  Because the striker piece and the transmission part are formed in two separate parts, it is possible to modify the striker piece without modifying the rest of the locking device to adapt the locking device to several types of leaf.

  For example, the strike piece can be replaced by another piece of strike or the same piece of strike can be positioned in several possible configurations, each configuration being adapted to the locking of a type of leaf.

  The same locking device can thus be used for leaves opening in a given direction or in an opposite direction.

  The device may advantageously have the following characteristics: the device comprises a roller adapted to cooperate with the cam surface to convert the actuating movement in the first direction of movement of the striker piece in the second direction; cam is formed by a light inclined relative to the first direction and the second direction, - the coupling part comprises two bosses adapted to abut against the roller to prevent movement of the striker piece when the strike piece is is respectively in the locked position and in the unlocked position, - the device comprises a housing, the coupling part being slidably mounted on the housing, - the coupling part is slidably mounted in the second direction, - the housing comprises at least one rib of guide, the coupling piece being able to bear on the rib to guide the piece of The first direction and the second direction are substantially perpendicular to each other, the striker piece is adapted to be connected to the coupling member selectively in a first configuration in which the device allows the locking of the coupling member. a flap opening by pivoting in a first direction of rotation and in a second configuration in which the device allows the locking of a flap opening by pivoting in a second direction of rotation, opposite to the first direction, - the piece of striker is adapted to be connected to the coupling member selectively in a first configuration and a second configuration, the striker piece to be returned with respect to the coupling member to pass from the first configuration to the second configuration, - the device comprises an anchoring element adapted to be driven in translation in the first direction by the actuating movement between a locked position in which the anchoring element is adapted to be inserted into a ground receiving port and an unlocked position in which the anchoring element is adapted to be extracted from the receiving orifice, - the device comprises a cable capable of driving the anchoring element in translation to unlock the anchoring element, - the device comprises a linear actuator comprising an output rod and a transmission part comprising a part extending between the actuator and the coupling member, said portion being substantially aligned with the output shaft of the actuator, - the device comprises a housing formed in two substantially symmetrical parts, one of the parts being adapted to be fixed on a wall to lock a flap opening by pivoting in a first direction of rotation and the other part being able to be fixed on a wall for locking a flap opening by pivoting in a second direction of rotation, opposite the first direction, so that the device can be fixed optionally on one or the other flap, 2888601 4 - each part has an arranged opening of to be selectively obstructed or disengaged by the striker member to selectively receive or release the bolt.

  The invention also relates to a gate with two leaves, in which one of the wings supports a bolt and the other leaf supports a locking device as defined above, the bolt being adapted to be received in the lock to lock the flap supporting the bolt.

  Other features and advantages will become apparent from the description which follows, which is purely illustrative and not limiting and should be read with reference to the appended drawings in which: FIG. 1 schematically represents a locking device according to a embodiment of the invention, - Figures 2 and 3 schematically represent the locking device respectively in the locked position and unlocked position, - Figures 4 and 5 show schematically a gate with two leaves provided with a lock and a locking device, the locking device being installed on the left leaf, respectively in the locked position and in the unlocked position, - Figures 6 and 7 show schematically a double leaf gate with a lock and a 'a locking device, the locking device being installed on the right wing In the locked position and in the unlocked position respectively, FIG. 8 schematically shows a striker piece.

  In FIG. 1, the locking device shown comprises a housing 100, an actuator 200, a transmission part 300, a pawl 400, a coupling part 500 and a striker piece 600.

  The housing 100 is provided to contain the actuator 200, the transmission part 300, the pawl 400, the coupling part 500 and the striker piece 600. The housing 100 is formed of two symmetrical half-boxes 101 and 102 intended to be assembled with each other by means of screws.

  Each half-casing 101, 102 has a plane wall 107, 108.

  Each half-housing 101, 102 respectively has an opening 105, 106 revealing the striker piece 600 outside the housing 100. Each opening 105, 106 is formed by a recess forming a recess in the plane wall 107, 108.

  The actuator 200 is a linear electric actuator of short stroke, of the type used in the locking devices of motor vehicle doors. The actuator 200 comprises a body 201 and an outlet rod 202 that can be displaced in translation relative to the body 201 in a first direction X on a given stroke.

  The transmission part 300 has a generally planar shape and extends in a plane parallel to the XY plane. It comprises four branches 301, 302, 303 and 304. The first branch 301 extends in the first direction X. The second branch 302 extends in a second direction Y, perpendicular to the first direction X. The third branch 303 s extends in the first direction X. The fourth leg 304 extends in the second direction Y. The transmission member 300 is slidably mounted on the housing 100 in the first direction X (direction of operation).

  The first branch 301 of the transmission part 300 has in the region of its lower free end holes 311 and 321 intended to allow the attachment of a cable connected to an anchoring element.

  Furthermore, the second branch 302 of the transmission part 300 comprises a beveled end face 312, inclined with respect to the first direction X and with respect to the second direction Y. The beveled end face 312 is able to come in contact with the pawl 400.

  The outlet rod 202 of the actuator 200 has in the region of its upper free end a finger 203. The finger 203 of the outlet rod 202 is engaged in an opening in the third leg 203 of the transmission part 200.

  The pawl 400 comprises a generally L-shaped element 401 rotatably mounted on the housing 100 via a pin 402. The pawl 400 also comprises a return spring (not shown) able to come 2888601 6 press the element 401 against the end face 312 of the second branch 302 of the transmission part 200.

  The housing 100 includes an orifice 109 disposed opposite the element 401. The orifice 109 is intended to allow the element 401 to extend in part to the outside of the housing when the element 401 pivots.

  The coupling part 500 comprises a plate 501 in which is formed an oblong through-hole 502 inclined with respect to the first direction X and with respect to the second direction Y. The coupling piece 500 also comprises two openings 504 and 505 disposed from and other light 502, and four pads 506, 507, 508 and 509.

  The light 502 forms a cam surface 503 inclined with respect to the first direction X and with respect to the second direction Y. The light 502 has at each of its ends bosses 504 and 505. Such bosses 504 and 505 can are obtained by extending each end of the light 503 by an opening extending in the first direction X. The coupling piece 500 is slidably mounted on the housing 100 in the second direction Y. For this purpose, each demiboite has ribs 103 and 104 rectilinear extending parallel to the second direction Y. The coupling piece 500 extends between the ribs 103 and 104, the pads 506, 507, 508 and 509 being able to bear on the ribs 103 and 104 for guide the coupling piece 500 in translation.

  The transmission part 300 has, in a region at which the third leg 303 is connected to the fourth leg 304, a roller 305 rotatably mounted relative to the transmission member 300. The roller 305 is engaged in the oblong slot 502 of the coupling piece 500.

  The bosses 504 and 505 are arranged to form stops that prevent the displacement of the coupling member 500 in translation in the second direction Y when the roller 305 is at one or the other end of the light 502 .

  The third leg 303 of the transmission member 300 extends between the output shaft 202 of the actuator 200 and the coupling member 500, and is aligned with the outlet rod 202.

  The striker member 600 (also shown in FIG. 8) comprises a locking wall 601, a fixing wall 602 and two guide walls 603, 604. The guide walls 603, 604 and the locking wall 601 form a U, the guide walls 603 and 604 forming the two lateral branches of the U. The guide walls 603 and 604 are able to bear on the ribs 103 and 104 of the housing 100 to guide the latch piece 100 in translation in the second direction Y. The locking wall 601 extends parallel to the walls 107 and 108 of the half-housings 101 and 102 and parallel to the XY plane. The fixing wall 602 extends in a plane perpendicular to the plane of the locking wall 601.

  The striker member 600 includes a straight slot 605 extending in the first direction X. The fourth leg 304 of the transmission member 300 passes through the slot 605 at the free end of the fourth leg 304.

  The striker piece 600 is intended to be fixed by means of screws on the coupling part 500. For this purpose, the wall 602 for attaching the striker piece 600 is able to be fixed on the pads 506 and 508 of the part coupling 500.

  In Figure 2, the locking device is in the locked position. In this position, the locking wall 601 of the striker piece 600 obstructs the opening 105 formed in the half-casing 101.

  When a control voltage is applied to the actuator, the output rod 202 moves in the first direction X and causes the finger 203 to translate upwards in the first direction X of the workpiece. transmission 300.

  The translation movement in the first direction X of the transmission part 300 is converted into a translation movement in the second direction Y of the coupling part 500 with respect to the housing 100, via the roller 305 and the surface of cam 503.

  The roller 305 and the cam surface 503 cooperate to form a motion reversal so as to convert the translational movement of the transmission member 300 in the first direction X (actuating movement) into a translation movement of the coupling piece 500 in the second direction Y. The striker piece 600 is driven in translation by the coupling piece 500 in the second direction Y, which has the effect of retracting the striker piece 600 in the housing 100 and of release the opening 105 formed in the half-casing 101 Furthermore, the translation along the first direction X of the transmission member 300 releases the pawl 400 which pivots and blocks the transmission part 300 in the unlocked position.

  In Figure 3, the locking device is in the unlocked position.

  As can be seen in this figure, the L-shaped member 401 extends partly outside the housing 100 through the orifice 109.

  When the device is in the locked position (FIG. 2), the boss 505 forms a stop capable of bearing against the roller 305 to prevent any displacement of the coupling piece 500 along the second direction Y under the effect of a solicitation. of the striker piece 600 or the coupling piece 500 in the second direction Y. Similarly, when the device is in the unlocked position (FIG. 3), the boss 504 forms a stop capable of bearing against the roller 305 to prevent any displacement of the coupling piece 500 in the second direction Y under the effect of a biasing of the striker piece 600 or the coupling piece 500 in the second direction Y. The bosses 504 and 505 formed in the light 502 avoid that the locking device can be actuated by manually moving the striker piece 600. The bosses 504 and 505 thus make the locking device irreversible.

  In Figure 4, the gate shown comprises two leaves 1 and 2. The wing 1 (right wing) is a flap movable in rotation and the wing 2 (left wing) is a semi-fixed leaf.

  2888601 9 The flap 1 opens by pivoting in a first direction of rotation.

  For the passage of a vehicle, the two leaves 1 and 2 can be opened, while for the passage of a pedestrian, only the wing 1 can be open.

  The movable wing 1 is equipped with a lock 11, of conventional type, comprising a first bolt 11 actuated by a handle 12 and a second bolt 14 which can be actuated by a key (by inserting the key into a lock hole).

  The semi-fixed wing 2 is equipped with a locking device identical to the device shown in FIGS. 1 to 3. The locking device is fixed on the wall of the wing 2 via the half-casing 102.

  The locking device is positioned in front of the lock 11 so that the bolts 12 and 14 can be engaged in the striker piece 600. The striker piece 600 is connected to the coupling piece 500 in a first configuration, so that the bolts 12 and 14 can be introduced between the wall 601 for locking the striker piece 600 and the wall of the wing 2.

  The locking device further comprises a cable 701 whose one end is fixed to the first leg 301 of the transmission part 300 through the orifices 311 and 321 and whose other end is provided with an anchoring element 702. L anchoring element 702 consists of a metal part.

  When the locking device is mounted on the gate, the cable 701 extends in a generally vertical direction (first direction X). The cable 701 is held taut by the weight of the anchoring element 702.

  The locking device also comprises a telescopic sheath 703 extending along the wall of the leaf 2 between the transmission part 300 and the anchoring element 701. The cable 701 extends inside the telescopic sheath 703. The telescopic sheath 703 serves to guide the cable 701 in translation and prevents access to the cable 701.

  The anchoring element 702 is capable of being inserted into a receiving orifice 3 provided for this purpose in the ground. The fact that the sheath 703 is telescopic makes it possible to adapt the length of the sheath 703 to the dimensions of the wing 2. Likewise, the cable 701 can easily be cut to a length adapted to the dimensions of the leaf 2.

  In Figure 4, the locking device is in the locked position. In this position, the latching wall 601 of the striker piece 600 obstructs the opening 106 formed in the half-casing 102. In addition, the bolts 12 and 14 extend between the wall 601 for locking the striker piece. 600 and the wall of the wing 2.

  Moreover, the anchoring element 702 is in the locked position. In this position, the anchoring element 702 extends partly into the receiving orifice 3.

  In this situation, the semi-fixed wing 2 is immobilized in the closed position by the anchoring element 702, while the movable wing 1 is immobilized in the closed position by the striker piece 600.

  When a control voltage is applied to the actuator 200, the output shaft 202 of the actuator moves in the first direction X, resulting in an upward translation of the transmission member 300.

  The translation of the transmission part 300 simultaneously causes the translation of the anchoring element 702 in the first direction X through the cable 701 and the translation of the striker piece 600 in the second direction Y. This has for effect of extracting the anchoring element 702 out of the orifice 3 and retract the piece of striker 600 to release the bolts 12 and 14, so that the leaves 1 and 2 are free to rotate.

  In Figure 5, the gate is in the unlocked position. In this situation, the two wings 1 and 2 can be opened, either manually or with the aid of a suitable motorized device, starting by opening the flap 1 mobile.

  2888601 11 The opening of the flap 1 movable causes immobilization by the pawl 400 of the transmission part 300 in the unlocked position. The pivoting element 401 then extends partly outside the housing 100, through the orifice 109.

  The transmission part 300 can be released only if the flap 1 mobile is closed again.

  When the gate must be closed, it closes the wing 2 slightly ahead of the wing 1 (either manually or with the aforementioned motorization device).

  When the movable leaf 1 is closed, the leaf 1 comes to urge the part of the pivoting element 401 extending outside the casing 100 and pivots the element 401 against the force exerted by the spring to release the transmission part 300.

  The transmission part 300 then moves in the first direction X, either under the effect of gravity, or with the aid of a spring (not shown) when it is provided, so that the device automatically returns to locked position.

  As a result, the striker piece 600 is returned to its locking position, receiving the bolts 12 and 14, and the anchoring element 702 is returned to its anchoring position in the orifice 3 (position of FIG. ).

  Thus, it is the simple closing of the flap 1 mobile, while the flap 2 semi-fixed is already closed, which automatically causes the locking of the gate, without any other electrical control is necessary.

  In Figures 6 and 7, the gate shown is identical to the gate of Figures 4 and 5, except that it is symmetrical with respect to the gate of Figures 4 and 5. The position of the wings 1 and 2 is reversed.

  The flap 1 movable in rotation (right flap) opens by pivoting in a second direction of rotation, opposite to the first direction of rotation.

  The flap 2 semi-fixed (left wing) is equipped with a locking device identical to the device shown in Figures 1 to 3. The locking device 2888601 12 is fixed on the wall of the wing 2 through the half -box 101.

  In FIGS. 6 and 7, the locking device has been turned 180 around the first direction X with respect to FIGS. 4 and 5.

  On the other hand, the striker piece 600 is connected to the coupling piece 500 in a second configuration, different from the first configuration, so that the bolts 12 and 14 can be introduced between the wall 601 of the locking piece. keeper 600 and the wall of the wing 2.

  More specifically, the striker piece 600 must undergo a reversal, that is to say a rotation of 180, with respect to the coupling part 500 about an axis parallel to the second direction Y to pass from the first configuration to the second configuration.

  When the locking device is in the locked position (FIG. 6), the wall 601 for locking the striker piece 600 obstructs the opening 107 formed in the half-casing 101.

  Thus, the same locking device can be used for different types of portals. The housing 100 being symmetrical, it can be fixed on a leaf, either through the flat wall 107 or through the flat wall 108. In addition, the piece of striker 600 can be connected to the room coupling in the first or second configuration as appropriate.

  Finally, it will be noted that the gate equipped with the locking device can be maneuvered manually in an extremely simple manner for the user. This may be the case for example when no power source is available to power the actuator 200, and in particular, in the case of a gate unlocking and / or remote controlled opening, when the user has not his remote control box on him.

  In this case, starting from the locked position (Figures 4 and 6), the user actuates the handle 13 (and previously if necessary the key) of the lock 11 to clear the bolts 12 and 14. The wing 1 is released. After opening thereof, the user can, with his finger, lift the transmission part 300 by acting on the free end of the fourth leg 304 which extends through the slot 605 and which protrudes between the wall 601 and the wall of the wing 2.

  By this movement, the anchor 702 is extracted from the orifice 3 via the cable 701. In addition, the striker member 600 is moved to the unlocked position (Figures 5 and 7). We then find ourselves in exactly the same situation as when the locking device is actuated electrically using the actuator 200.

  It will be observed here that the manual operation of the device is both extremely simple and extremely safe because the transmission part 300 is movable by the user only when the mobile flap 1 has begun to be opened, which requires that the user has the key of the lock.

  In addition, because as described above, the locking device automatically resumes its locking position as soon as the wings 1 and 2 are effectively closed, no further maneuver of the user is necessary after this reclosing.
