Description

Title of the invention: Anti-burglary lock for opening. Technical field of the invention

[0001] The invention relates to a lock for an opening. The invention also relates to an arrangement comprising such a lock. The invention also relates to an opening comprising such an arrangement or such a lock. The invention also relates to a vehicle comprising such an opening or such an arrangement or such a lock. State of the prior art

[0002] An opening generally comprises a lock connected to a lock to control the locking or unlocking of the opening of the opening. Such a lock generally comprises a rotor and a stator. A key specific to this lock makes it possible to rotate the rotor relative to the stator. Thus, to lock or unlock the opening of the opening, the specific key is inserted into the lock and turned. Such a lock has a security function since it makes it possible to prevent the opening of the opening.

[0003] Such a lock is for example used on a vehicle opening, such as a motor vehicle.

[0004] However, a person who does not have the key and is malicious can force the lock by moving the bolt and thus manage to control the lock to unlock the opening of the opening. This is particularly the case when the control between the bolt and the lock is a rod and / or the lock is fixed directly to an external wall of such a vehicle opening. As a result, the malicious person can enter the passenger compartment of the vehicle, stay there, damage it and / or steal objects stored in this passenger compartment. This situation is obviously not acceptable. Presentation of the invention

[0005] The aim of the invention is to provide a lock which overcomes the above drawbacks. In particular, the invention proposes a solution for uncoupling a drive means of a lock at a lock. Summary of the invention

[0006] To achieve this objective, the invention relates to a lock for an opening, in particular for a vehicle opening, in particular a motor vehicle, comprising a stator, a rotor capable of pivoting about a main axis, and a lever, the rotor being intended to pivot relative to the stator, in particular following the insertion and pivoting of a key within the rotor, so as to cause the lever to pivot about the main axis, the lock comprising a means for fixing the lever to the breakable rotor and / or separable.

[0007] The fixing means may comprise a first means provided on the rotor and a second means provided on the lever, the first and second means being able to cooperate to ensure the fixing of the lever on the rotor.

[0008] The first means may comprise a protrusion provided projecting from the rotor, the protrusion being able to extend or extend substantially along the main axis, and the second means may comprise at least two tabs, in particular symmetrical or substantially symmetrical with respect to the main axis.

[0009] The invention also relates to an arrangement for an opening, in particular for a vehicle opening, in particular a motor vehicle, comprising a lock as defined above, the arrangement comprising a lock and a rod-type movement transmission means between the lever of the lock and the lock.

[0010] The invention also relates to an opening, in particular a vehicle opening, in particular a motor vehicle opening, comprising an external wall comprising an internal face and an arrangement as defined previously, the lock being fixed on, or at, or through the external wall.

[0011] The lever may comprise a means for securing the lock relative to the external wall, so that the securing means opposes tilting and / or extraction by coming into contact with the internal face of the external wall in the event of a tilting movement of the lock, in particular from top to bottom and vice versa, and / or in the event of an extraction movement of the lock towards the outside of the external wall.

[0012] The means for securing the lock may comprise two tabs extending towards the external wall, in particular two tabs which are symmetrical or substantially symmetrical with respect to the main axis of the lock.

[0013] Each leg may comprise a support foot intended to come into contact or substantially into contact with the internal face of the external wall, in particular a support foot extending radially or substantially radially relative to the main axis.

[0014] The opening may comprise at least one element arranged opposite the lever and the lever may comprise a means for preventing the lock from being pushed in so that the means for preventing it from being pushed in comes into contact with the at least one element in the event of the lock being pushed in relative to the external wall.

[0015] The anti-sinking means may have a cylindrical or substantially cylindrical shape with an axis coincident or substantially coincident with the main axis.

[0016] The invention also relates to a vehicle, in particular a motor vehicle, comprising an opening as defined previously or an arrangement as defined previously or a lock as defined previously. Presentation of figures

[0028] The direction in which a vehicle, in particular a motor vehicle, moves in a straight line is defined as the longitudinal direction X. By convention, the direction perpendicular to the longitudinal direction, located in a plane parallel to the ground, is called the transverse direction Y. The third direction, perpendicular to the other two, is called the vertical direction Z. Thus, a direct XYZ reference frame is used in which X is the longitudinal direction in the front-rear direction of the vehicle, therefore directed towards the rear, Y is the transverse direction directed towards the right and Z is the vertical direction directed upwards. The forward direction corresponds to the direction in which the vehicle usually moves in the longitudinal direction and is opposite to the rear direction.

[0029] [Fig.l] schematically illustrates a vehicle 1, preferably a motor vehicle. The vehicle comprises at least one opening 2. As illustrated in [Fig.l], the opening 2 is a left front door. The opening 2 comprises an arrangement 3.

[0030] The following description and the directions illustrated in the figures relate to such a left front door.

[0031] Preferably, the vehicle comprises more doors, for example a right front door also comprising an arrangement. Alternatively, or in addition, the vehicle comprises other doors, such as rear doors, in particular left and / or right rear doors. Optionally, the rear door(s) may comprise an arrangement.

[0032] More specifically, as illustrated in [Fig.2], the arrangement 3 comprises a lock 10. The lock 10 comprises a lever 20 which will be detailed later. The arrangement 3 further comprises a lock 4. The arrangement 3 further comprises a movement transmission means 5 between the lever 20 of the lock 10 and the lock 4. Preferably, the movement transmission means between the lock 10 and the lock 4 is of the rod type. By rod, we mean a rod, for example of circular section, relatively rigid. The rod 5 comprises a first end 5', for example bent and / or curved and / or forming a right angle, so as to be able to be inserted within, or at the level of, an orifice 21 formed in the lever 20.

[0033] Note that the orifice 21 is for example cylindrical and of diameter for example just greater than the diameter of the first end 5' (in the case of a rod of circular section) so as to cooperate with a small clearance with the first end 5'.

[0034] Alternatively, as illustrated in [Fig. 2], the orifice 21 is oblong or substantially oblong, for example with a major axis extending vertically or substantially vertically. In this case, a substantial clearance J1 is preferably provided between the orifice 21 and the first end 5' so as to tolerate movements of the lever without having any action on the rod 5.

[0035] Alternatively, as illustrated in [Fig.4], the orifice 21 allows the attachment of a hook-type clip 25, intended to pinch or substantially pinch a portion of the first end of the rod. In the case of a cylindrical orifice 21, preferably the clip 25 can pivot within the orifice so as to allow pivoting of the first end of the rod relative to the lever 20.

[0036] As illustrated in [Fig.2], the rod 5 comprises a second end 5”, for example bent and / or curved and / or forming a right angle, so as to be able to be inserted into an orifice 9 provided in an actuating arm of the lock 4. For example, the second end 5” of the rod 5 cooperates with the orifice 9 without play, or substantially without play, provided in the actuating arm of the lock.

[0037] More precisely, as illustrated in [Fig. 3], the lock 10 comprises a stator 11 and a rotor 12. The rotor 12 is able to pivot about a main axis A relative to the stator 11. The lock also comprises a lever 20 illustrated generally in FIGS. 2, 4, 5 and 6.

[0038] Preferably, after inserting the key adapted to the lock and pivoting this key within the lock, the rotor 12 pivots relative to the stator 11. This results in the lever 20 being driven to pivot around the main axis A.

[0039] As illustrated in particular in [Fig. 4], the lock 10 comprises a means 22 for fixing the lever 20 on the rotor 12 which is breakable, breakable, and / or separable, disengageable, disengageable, uncoupleable. More precisely, the fixing means 22 comprises a first means 30 provided on the rotor 12 and a second means 40 provided on the lever 20, illustrated in FIGS. 3 and 5. Thus, the first and second means 30, 40 cooperate to ensure the fixing of the lever 20 on the rotor 12, in particular by clipping. In other words, the means 30, 40 ensure the mechanical connection, for example of the embedding type, between the lever 20 and the rotor 12. Preferably, the breakage or separation is intended to take place, if necessary, at the level of the cooperation between the first means 30 and the second means 40.

[0040] For example, as illustrated in [Fig. 3], the first means 30 comprises a protrusion 31 provided projecting from the rotor 12. The protrusion 31 extends, or extends substantially, along the main axis A. For example, the protrusion 31 comprises two U-shaped or grooves 32 extending radially or substantially radially relative to the axis A. In this case, as illustrated in particular in [Fig. 6], the second means 40 comprises two tabs or clips or blades 41, 42. For example, the tabs are symmetrical, or substantially symmetrical, relative to the main axis A. The tabs 41, 42 are inserted into the rails or grooves 32, preferably without play, or with minimal play, so as to ensure the driving of the lever 20 by the rotation of the rotor 12 (driven by the rotation of a key for example). at the level of protuberance 31.

[0041] Alternatively, more matching tongues and grooves may be suitable. Other male / female shapes may also be suitable to provide the attachment means between the rotor and the lever.

[0042] Note that the tabs 41, 42 preferably extend from supports 43, 44. These supports are preferably not parallel to the main axis A. Preferably, the supports 43, 44 are symmetrical or substantially symmetrical with respect to the axis A. Preferably, as illustrated in [Fig. 6], the supports are oblique and approach the axis A in the direction of the tabs 41, 42.

[0043] As illustrated in Figures 1 and 4, the door 2 comprises an outer wall or exterior panel 6. This outer wall 6 comprises an inner face 7, that is to say a face oriented towards the interior of the vehicle. As a reminder, [Fig. 4] corresponds to the left front door of the vehicle 1. The door 2 comprises the arrangement 3 (not illustrated in full in [Fig. 4]). The lock 10 is fixed on, or at, or through the outer wall 6. Preferably, the lock 10 comprises a shoulder 13 projecting from the side exterior of the wall 6 of the door 2. For example, the lock is inserted into the wall 6 from the outside, until it makes contact against this shoulder 13. The lock 10 is held in position relative to the external wall 6, preferably by a clip or fork or fork 15 which is inserted into substantially rectilinear grooves 16 provided on either side of the stator 11. The clip 15 has, for example, a general non-planar U shape. Consequently, by inserting it into the grooves 16, the clip 15 is under stress due to its non-planar shape. Preferably, the clip is obtained from an elastic material, in particular spring steel. Thus, the clip 15 creates a force against the internal face 7 of the wall 6 once it is placed in the groove(s) 16 of the stator 11. Thus, the clip presses and holds the shoulder 13 of the lock against an external face of the external wall.

[0044] Note that the tabs can extend towards the internal face 7 as illustrated in [Fig.6], or in the opposite direction, i.e. towards the passenger compartment, as illustrated in [Fig.10]. The first means 30 of the rotor 12 is in any case adapted to cooperate with the second means 40 of the lever 20, in particular with the shape of the tabs and their direction of extension.

[0045] As illustrated in [Fig. 4], the lever 20 comprises a securing means 50, 55 for securing the lock 10. The securing means comprises an anti-tilt element 50 for securing the lock 10. Preferably, the securing means further comprises an anti-extraction element 55 for securing the lock 10 relative to the external wall 6. For example, the anti-tilt element 50 and the anti-extraction element 55 are common. More precisely, the anti-tilt element 50 and / or the anti-extraction element 55 extend towards the internal face 7 of the wall 6 so as to come into contact with the internal face 7 in the event of a tilting or rattling movement of the lock 10 or an extraction movement of the lock. By nodding or rocking the lock is meant movements, including back and forth, for example from top to bottom and vice versa, and / or from left to right and vice versa.By extraction movements of the lock 10 towards the outside of the external wall 6, we mean movements resulting from the application of forces on the lock towards the outside of the vehicle, for example forces applied along the main axis A.

[0046] As illustrated in Figures 7, 9 and 10, the anti-tilt element 50 of the lock 10 and / or the anti-extraction element 55 of the lock 10 comprises two tabs 51, 52. Each tab extends towards the external wall 6. For example, the two tabs 51, 52 are symmetrical, or substantially symmetrical, with respect to the main axis A of the lock 10. Preferably, each tab 51, 52 respectively comprises a support foot 53, 54 intended to come into contact or substantially into contact with the internal face 7 of the external wall 6 in the event of the movements mentioned above. For example, each support foot 53, 54 extends radially, or substantially radially, with respect to the axis main axis A of the lock. For example, as illustrated in Figures 9 and 10, the tabs 51, 52 are, or comprise, portions of the same cone of axis A or substantially of axis A widening in the direction of the external wall 6. Preferably, as illustrated in [Fig.4], a clearance J2 in the direction of the main axis A between the anti-tilt element and / or the anti-extraction element 50, 55 and the internal face 7 is provided. Thus, any tilting or extraction movement is limited in terms of stroke length by the clearance J2 as will be detailed later.

[0047] Advantageously, as illustrated in [Fig. 7], a free space between the ends of the legs 51, 52 on the side of the internal face 7 or, where appropriate, between the support feet 53, 54 corresponds to a cylinder of external diameter D and of axis coincident or substantially coincident with the main axis A. In other words, despite the rotation or pivoting of the lever 20 and consequently the pivoting of the anti-tilting and anti-extraction elements, a free space of cylindrical shape of external diameter D remains.

[0048] On the one hand, this cylindrical or substantially cylindrical free space is intended to receive part of the volume of the lever 20 as illustrated in [Fig. 10]. On the other hand, this free space ensures above all a pivoting of the lever 20 and the anti-tilt and / or anti-extraction elements without interference, that is to say without contact, with the clip 15 (illustrated in [Fig.4]) holding the lock 10 on the wall 6. Thus, the external diameter D of this free cylindrical space is such that it does not interfere with the clip 15. In other words, the clip 15 in the lock holding position is inscribed in a cylinder of axis A or substantially of axis A and of diameter less than the diameter D. The gaps E between the clip 15 and the cylindrical space of diameter D illustrate the margin making it possible to avoid any interference between the elements 50, 55 and the clip 15, in particular during the pivoting of the lever 20.Thus, the rotor and its lever rotate normally without interference when using the key in the lock.

[0049] Preferably, as illustrated in Figures 4, 8, 9 and 10, the lever 20 comprises an anti-pushing means 60 for the lock 10. Thus, in the event of the lock 10 being pushed into the door panel, the anti-pushing means 60 comes into contact with an element arranged between the outer panel 6 of the door and an inner panel (not shown). For example, as illustrated in [Fig. 4], the door 2 comprises an element 8. In the event of the lock 10 being pushed in, the anti-pushing means 60 comes into abutment against the element 8 so that the lock is blocked and cannot move back further in the transverse direction. To do this, the opening therefore comprises at least one element 8 arranged opposite the lever 20. Preferably, this element 8 is a part already present within the door box, if possible rigidly fixed within the door box and preferably fixed within the door box.In other words, element 8 is a part with a function within the door.

[0050] Alternatively, the element 8 is added within the box of the door 2 so as to create a stop which cooperates with the anti-pushing means during an attempt to push the lock. In this case, the element 8 is for example obtained from plastic material so as to be rigid while having a low mass, for example by comprising ribs.

[0051] Preferably, the anti-sinking means 60 has a cylindrical or substantially cylindrical shape with an axis coincident or substantially coincident with the main axis A. The anti-sinking means extends towards the interior of the vehicle, along or substantially along the main axis A.

[0052] Note that figures 1, 2, 3, 5 and 6 do not illustrate the securing and anti-sinking means.

[0053] Preferably, the anti-tilt and anti-extraction elements are integral with the lever 20. More preferably, the anti-sinking means are integral with the lever. Advantageously, the securing and anti-sinking means are integral with the lever.

[0054] Alternatively, each means 50, 55, 60, or at least one of these means, is a specific part. This part or these parts are then fixed to the lever 20, in particular by clipping.

[0055] In summary, the solution is a tamper-evident device for a lock fixed in full skin, that is to say through an external door panel, in particular when the drive mechanism of the corresponding lock is of the rod type.

[0056] More precisely, during an attempted break-in by shaking the lock and / or extracting the lock, the securing means 50, 55 prevents tilting and / or extraction by coming into contact with the internal face 7 of the panel 6. Indeed, the clearance J2, illustrated in [Fig. 4] prevents immediate contact of the securing means 50, 55, in particular the support feet 53, 54, against the internal face 7. This results in a slight tilting, or a slight extraction, of the lock relative to the wall 6. This tilting or extraction movement, although it is limited, causes the disengagement of the tabs 41, 42 of the lever 20, for example from the grooves 32 of the protuberance 31 formed at the end of the rotor 12. Alternatively, such tilting and / or extraction movements cause the deterioration or breakage of one or more tabs or clips 41, 42 and / or damages or breaks at least partially at least one groove 32.In any case, the fixing means 22 of the lever 20 on the rotor 12 is adapted to disengage, preferably to break, in the event of jerking and / or extraction movements, even limited in terms of travel by the clearance J2. For example, the lever 20 and / or the rotor 12 at the level of their fixing means 22 relative to each other is breakable, or partially breakable.

[0057] Preferably, the fixing means 22 between the lever 20 and the rotor 12 is a compromise in terms of mechanical resistance between, on the one hand, ensuring a built-in connection to ensure the normal rotor / lever drive function in the absence of abnormal stress on the lock, and on the other hand, breaking in the event of tilting or extraction movements of the lock relative to the wall 6.

[0058] As a reminder, the clearance J2 extends substantially in the direction of the main axis A between the internal face 7 and the end directed towards the outside of the vehicle of the anti-vibration element 50 and / or the anti-extraction element 55. Preferably, the supports 43, 44 and / or the tabs 41, 42 ([Fig.6]) are dimensioned to break and / or twist, in particular thanks to extension angles relative to the axis A facilitating this breakage or twisting. More preferably, the thickness of the supports 43, 44 is predetermined to cause this breakage and / or twisting. For example, areas of lesser thickness are provided so as to create points or areas of rupture of the tabs 41, 42 and / or the supports 43, 44. In any case, in the event of jerking and / or extraction movements, the control lever 20 becomes detached from the lock, in particular from the rotor 12 of the lock, which makes the rod inoperative for unlocking the lock 4.

[0059] Thus, the lever cannot be driven into pivoting as if the lock had been extracted from the wall 6. The rod 5 does not remain accessible so that it cannot be driven towards a position for releasing the lock 4. Since the stroke of the nods is limited, the rod does not move sufficiently before the lever / rotor is detached to generate a movement on the arm of the lock. In summary, no means of actuating the release of the lock is viable so that such a break-in is impossible.

[0060] More precisely, during an attempt to break in by pushing the lock towards the inside of the vehicle, the anti-push means 60 takes up the play J3 (illustrated in [Fig.4]) under the effect of the movement of the lock along, or substantially along, the main axis A. It should be noted that this play J3 between the means 60 and the element 8 is preferably small, or even very small. This clearance J3 being quickly taken up, the contact between the means 60 and the element 8 prevents a significant travel of the lock towards the interior of the vehicle which would cause the lock 10 to become detached from the outer wall 6. The fork 15 thus continues to play its role of holding the lock on the wall 6 by pressing on the one hand within grooves provided in the stator 11 and on the other hand against the inner face 7 of the wall 6. The sinking of the lock into the door box is avoided, at least limited to the travel of the clearance J3.In other words, this contact with the element 8 stops the lever 20 from being pushed in and consequently the lock from being pushed inside the door box 2. No access within the transmission of movement towards the lock at the level of the lock is then possible by pushing the lock into the exterior door panel.

[0061] Thus, the lock cannot be driven into pivoting as if it had been detached from the wall 6. The rod 5 does not remain accessible so that it cannot be driven towards a position for releasing the lock 4. In summary, no means of actuating the release of the lock is viable so that such a break-in is impossible.

[0062] As seen previously, the anti-shake / extraction function and the anti-sinking function can be implemented independently or combined on the lever. Preferably, the functions are integrated on the lever which is then a single part, for example molded, for example made of plastic. In this case, tabs 51, 52 and a cylindrical part 60 extend on either side of a main part of the lever. Alternatively, each function can be integrated on an independent part, for example obtained by molding in plastic, for example clipped or glued, on a lever.

[0063] Note that the solution does not increase the complexity of mounting the lock or the time required, no additional operation being necessary. Only the fixing of the lever 20 on the rotor 12 of the lock 10, preferably the tabs 41, 42 in the grooves 32 of the protuberance 31, for example by clipping, is to be provided per lock.

[0064] Thanks to the solution, the resistance to break-in by rattling and / or extraction and / or pushing in of the rod lock control locks is greatly improved. The solution has no impact on the operation of the lock, the securing and anti-pushing means which are pivotally movable with the rotor and the lever having shapes designed to move sufficiently away from the fixed parts, in particular from the fork 15 for holding the lock on the panel 6.

[0065] Thus, a person who does not have the key and is malicious cannot unlock the lock by moving the bolt. Controlling the lock to unlock the opening of the opening without the appropriate key is not possible. A malicious person cannot therefore enter the passenger compartment of the vehicle, stay there, damage it and / or steal objects stored in this passenger compartment.

[0066] As a remark, the solution therefore achieves the desired objective of providing an anti-theft lock with rod lock control and has the following advantages: - it is economical since it only involves the modification of a single part, namely the lock lever also called a thresher, - it can be used on other vehicles comprising a passenger compartment, such as construction machinery, agricultural machinery, or floating boats, aircraft, in particular in the case where the transmission means between the lock and the latch is a rod and / or the lock is fixed directly to an external wall.

[0067] Although the solution has been described as an application to a vehicle opening, it can be adapted to an opening of a building, of a piece of furniture, in particular in the case of device using a movement transmission system to a rod-type lock.
