Description

Kit for the development of a self-supporting set of electronic lock

The present invention relates to a kit for producing a self-supporting electronic lock assembly, to a self-supporting electronic lock assembly made from such a kit as well as to a method of manufacturing such a set of freestanding electronic lock.

The field of the invention is that of door locks, and in particular electronic locks of which a rotor of the cylinder is provided to be actuated in rotation by means of an actuator, and in particular an electric motor, said actuator being controlled by via a control means, in particular a computer means, such as for example a mobile telephone.

For example, document FR 1758530, in the name of the Applicant, shown in FIG. 1, discloses a self-supporting electronic lock assembly 1′ configured to open/close a door, having an electronic lock comprising a lock cylinder 2′ with a stator 21' and a rotor 22', to which a bit is fixed, as well as a drive unit 3' comprising an electric actuator 32' configured to modify the state of the electric lock, from an open state to a closed state, or vice versa.

As can be seen in FIG. 1 representing such a state of the art, said drive unit 3' comprises a housing 31' receiving said electric actuator 32', in particular an electric motor 32', a coupling means 4' being provided between the output S32' of the electric actuator 32' and the cylinder rotor.

A second rotor (not shown) can also be provided, also fixed to said bit, and advantageously positioned in stator 21', on the other side of the bit, and configured to be rotated by means of a key.

The cylinder 2' and the drive block 3' are secured together by means of fixing screws 51' received in tapped holes provided on the stator 21' of the cylinder 2', and whose head is positioned at the 'inside the box 31', bearing at the level of a flat wall 33' of the box 31'.

Also, said coupling means 4' is fixed to the rotor 22' of the lock cylinder 2' by means of a pressure screw 41', the head of which is positioned inside the housing 31' of the lock block. 'workout 3'.

According to the findings of the inventors, such an electronic lock assembly 1' has the drawback that said fixing screws 51', as well as said pressure screw 41', being positioned inside the housing 31', are accessible only when the box 31' is open, which in practice makes it necessary to assemble the lock cylinder 2' and the drive block 3' and to couple them together in the factory, prior to their distribution to the end customer.

According to the findings of the inventors, an inherent disadvantage of this design is that the drive block is assembled to the lock cylinder before the actual consumer need is known. In particular, the lock cylinder, to be compatible with a specific door, must often have a length adapted to the thickness of the door. Concretely and according to the findings of the inventors, such a design obliges the distributor to provide several self-supporting electronic lock sets in stock, all coupled with lock cylinders of different dimensions, and in particular different lock cylinder lengths, and while the drive boxes of each of the sets of electronic locks are identical.

Indeed, and according to this prior design, the drive block and said lock cylinder must be produced simultaneously, and assembled in the factory, before their transport and commercial distribution.

This also affects the handling and storage of said self-supporting electronic lock assembly 1′, in that it must be transported and stored with the drive block 3′ and the lock cylinder 2′ assembled together, which increases also the costs inherent in the storage and handling of such self-supporting lock assemblies.

Technical problem

The objective of the invention is therefore to overcome the drawbacks of the devices of the prior art by proposing a kit for the development of a set of self-supporting electronic lock making it possible to simplify and reduce the time necessary for assembly between the box receiving the actuator configured to drive the rotor of the cylinder and said cylinder in rotation, and also to reduce the overall cost price of the manufacture and distribution of such electronic lock assemblies, and in particular in the case where it is planned to make a plurality of such self-supporting lock sets with lock cylinders, of different sizes.

Another objective of the present invention is to facilitate the storage and handling of such a freestanding electronic lock assembly.

Another object of the present invention is to provide a method for producing a self-supporting electronic lock assembly from a kit according to the invention.

Another object, at least according to one embodiment, is to propose such a method intended for the development of a self-supporting electronic lock assembly, intended to correspond to several door thicknesses, with cylinders of suitable lengths, and allowing advantageously to reduce the number of references to be produced, stored and handled compared to the method known from the state of the art for which said lock cylinder and the drive unit are assembled and coupled together in the factory.

The drawings and the description below contain, for the most part, certain elements. They may therefore not only be used to better understand the present invention, but also contribute to its definition, if necessary.

Throughout the application, the longitudinal direction of the lock cylinder 2 corresponds to the direction along which the axis A2 of rotation of the rotor 22 substantially extends with respect to the stator 21.

The invention relates to a kit for producing a set 1 of freestanding electronic lock, configured to open/close a door or the like, said set 1 comprising:
- a lock cylinder 2 with a stator 21 and a rotor 22, rotatable relative to the stator 21 around a longitudinal axis A2 of the cylinder 2, rotating a bit,
- a drive unit 3 comprising a housing 31 receiving an actuator (not shown) with an output configured to drive the rotor 22 of the cylinder 2 in rotation with respect to the stator 21 of the cylinder 2 via a means 4 d rotating coupling,
- means 5 for securing the drive block 3 to the lock cylinder 2, configured to ensure the removable fixing of the lock cylinder 2 to the drive block 3, comprising a locking member 51 configured to ensure the locking of the securing from lock cylinder 2 to drive block 3.

Said kit comprises on the one hand, said lock cylinder 2, and on the other hand said drive unit 3, each advantageously in the assembled state, but however not coupled together.

Said means 4 of coupling in rotation, integral with the drive block 3, comprises a fitting part 41, configured to fit into a receiving portion 23 integral with the rotor 22 of the cylinder 2, in order to ensure the coupling in rotation of the output of the actuator with the rotor 22 of the cylinder 2 by simple fitting of the fitting part 41 of the coupling means 4 in the reception portion 23 integral with the rotor 22 of the cylinder 2.

Said means 5 for securing the drive block 3 to the lock cylinder 2 comprise, in addition to the locking member 51, a fixing means 52 secured to the drive block 3, projecting outwardly from said housing 31 of the block drive 3, configured to be inserted into a housing 25 provided in the stator 21 of the cylinder 2, and emerging from a longitudinal end E2 of the cylinder 2.

The stator 21 of the lock cylinder 2 has a bore 24 for receiving the locking member 51, and the fixing means 52 having a receiving portion 53 for receiving the locking member 51, configured so as to allow the assembly of the lock cylinder 2 and the drive block 3, each in the assembled state, by:
- interlocking of the interlocking part 41 of the rotary coupling means 4, integral with the drive block 3, in the receiving portion 23 integral with the rotor 22 of the cylinder 2,
- facing the bore 24 of the stator 21 with the receiving portion 53 of the fixing means 52 on the other hand, by inserting the fixing means 52 into the housing 25 provided in the stator 21 of the cylinder 3.

According to the invention, the locking member 51 is configured to allow the locking of the assembly between the lock cylinder 2 and the drive block 3, by its insertion, from outside the housing 31 of the drive block. drive 3, through bore 24 and receiving portion 53.

Throughout the present application, it is meant by the fact that the lock cylinder 2 and the drive unit 3 are in the assembled state, that all the elements composing them are assembled so that they are functional.

In particular, the fixing means 52 can advantageously also be assembled with the casing 31 of the drive unit 3 before assembly with the lock cylinder 2, and in particular in the case where its fixing on the said casing 31 requires having access to inside the box 31.

Also, said fixing means 52 can be provided in one piece on the housing 31 of the drive unit 3.

Thanks to the kit according to the invention, and in particular to the fact that said fixing means 52 projects outwards from the housing 31 of said drive unit 3, it is not necessary to have access to the interior of the housing 31 of the drive block 3 to effect the assembly between the drive block 3 and the lock cylinder 2. Likewise, the rotational coupling between the output of the actuator and the rotor 22 of the cylinder of lock 2, being made by simple fitting of the fitting part 41 of the means 4 for coupling in rotation, in the receiving portion 23, it is also not necessary to have access to the interior of the case 31 of the drive unit 3 to achieve this rotational coupling during assembly of the drive unit 3 and the lock cylinder 2 of said self-supporting lock assembly 1.

Thus, the assembly of the drive block 3 and the lock cylinder 2 of the self-supporting lock assembly 1 is particularly simple and quick to implement, and also reduces the cost price of such a lock assembly 1 self-supporting, in particular in comparison with the self-supporting lock assembly 1′ described in the document FR 1758530. Contrary to the aforementioned state of the art, it then becomes possible to physically assemble the drive block 3 to the lock cylinder 2 , when the latter are in the assembled state, which is impossible with the lock assembly 1′ described in the document FR 1758530.

Also, the handling and storage of such a lock assembly 1 are facilitated, in that the lock cylinder 2 and the drive block 3 can be transported and stored separately, each in the assembled state, and therefore not -coupled together.

Again, it then becomes possible for the manufacturer producing such self-supporting lock sets 1, or for the distributor selling them, or even for the end customer, to couple the two components (i.e. lock cylinder 2, and the block of drive 3), both in the assembled state, and advantageously, only after knowledge of the specific needs of the end customer, and in particular as regards his choices on the specific characteristics of the lock cylinder 2 (in terms of length in particular, or even other parameters).

This technical possibility advantageously allows the manufacturer or the distributor to reduce stocks compared to standard manufacture, for which said self-supporting electronic lock assemblies, including the lock cylinder and the drive unit, are all coupled together. in the factory, should cover this offer by necessarily presenting a number of lock cylinders produced in a number equal to the number of drive blocks.

According to the invention, by making it possible to couple said lock cylinder 2 with said drive unit 3, only after knowledge of the customer's need, it becomes possible to respond to the same request, admittedly with the same number of cylinder references. lock 2 to produce, store or handle, but substantially reducing the number of drive blocks 3 to produce, store or handle. In other words, it becomes possible for the manufacturer or the distributor to respond to the same commercial demand, but with an offer that significantly reduces the number of references to be produced, stored or handled compared to the state of the art, and therefore to reduce the costs inherent in this storage and in this handling, in addition to reducing the production costs of such sets of self-supporting locks 1 .

In a well-known manner, the actuator of the drive unit 3 may comprise a motor (not shown) positioned inside the housing 31, and configured to drive in rotation, directly or via a transmission, said fitting part 41 of the coupling means 4.

According to one embodiment, said bore 24 is provided opening into said housing 25 of cylinder 2.

The locking member 51 and said fixing means 52 can be configured so that the insertion of the locking member 51 through the bore 24 and the receiving portion 53 ensures the locking of the assembly between the lock cylinder 2 and the drive block 3 by, concomitantly:
- material interference between the locking member 51 and the fixing means 52, preventing relative movement between the fixing means 52 and the cylinder 2, preventing the removal of the fixing means from its housing,
- an elastic deformation of the fixing means 52 causing the fixing means 52 to bear against at least one inner wall P25 of the housing 25, so as to eliminate the mounting clearance between the fixing means 52 and the housing 25.

This advantageous arrangement of the invention makes it possible to ensure, in a simple manner, a rigid assembly between the lock cylinder 2 and the drive unit 3, with no relative play between the fixing part F52 and the housing 25, and therefore between drive block 3 and cylinder 2.

Indeed, the existence of an assembly clearance between the fixing part F52 and the housing 25 would allow relative movement (in particular in torsion) between the cylinder 2 and the drive unit 3, even with a short stroke, which could harm the operation of the self-supporting lock assembly 1, in particular at the level of the transmission between the motor of the drive unit 3 and the rotor 22 of the cylinder 2, via the coupling means 4 in rotation.

The elastic deformation of the fixing means 52 can advantageously be a bending deformation of the fixing means 52, and in particular a deformation of low amplitude.

According to one embodiment, said fixing means 52 comprises a fixing part F52 comprising two fixing lugs 54 substantially parallel to each other, said receiving portion being provided in part at the level of each of the fixing lugs 54, said fixing lugs 54 being configured to fit into the housing 25 made in the stator 21 of the lock cylinder 2, said housing 25 extending in a substantially longitudinal direction of the cylinder 2, said locking member 51 comprising a cylindrical portion F51, configured to be received in said receiving portion 53 extending along an axis A53 substantially perpendicular to said substantially longitudinal direction of cylinder 2, bore 24 having a first end E24 opening onto an outer side wall P2 of cylinder 2 and a second end E24' leading to said reception portion 53.

According to such an embodiment, said fixing lugs 54 and said locking member 51 are configured such that the insertion of the cylindrical portion F51 of the locking member 51 into said receiving portion 53 causes the separation of the fixing lugs 54 so as to pass:
- an unlocking position, in which the fixing lugs 54 are separated from the inner walls P25 of said housing 25,
- a locking position, in which the fixing lugs 54 find themselves resting against the inner walls P25 of said housing 25, in order to ensure the locking of the fixing of the lock cylinder 2 to the drive block 3.

Thus, thanks to this advantageous arrangement of the invention, the assembly between the drive block 3 and the lock cylinder 2 proves to be particularly simple and rapid, in that it is sufficient simply to insert the locking 51 in the bore 24 and in the receiving portion 53, so that the cylindrical portion F51 of the locking member 51 is received in the said receiving portion 53, to lock the attachment between the said drive block 3 and the lock cylinder 2.

More particularly, the insertion of the fixing part F52 in the housing 25 of the stator is facilitated when the two fixing lugs 54 are close to each other, with the presence of a clearance. The spacing of the two lugs fixing 54, caused by the insertion of the locking member 51, makes it possible to eliminate the clearance between the fixing part F52 and the housing 25 of the stator, and thus to improve the rigidity of the mechanical connection created between the lock cylinder 2 and the drive block 3, once only the locking member 51 is in place.

In addition, as visible in particular in the embodiments of Figures 2 to 5, said first end E24 of the bore 24 can be provided to open onto an outer side wall P2 of the cylinder 2 intended to end up in the field of the door. , once the self-supporting assembly 1 is installed on said door, thus making access to the locking member 51 impossible.

This therefore makes it possible to increase the security of the lock assembly 1 according to the invention, once it is installed.

As visible in the embodiments of Figures 2, 4 and 5, the fixing of the self-supporting lock assembly 1 to a door is done by means of a fixing screw (not shown) received in a hole formed in the field of the door, and in a threaded housing 26, formed in the stator 21 of the lock cylinder 2, said threaded housing 26 being advantageously able to open onto said outer side wall P2 of the lock cylinder 2.

Said fixing lugs 54 can be configured so as to be able to move away from each other by deforming elastically, so as to be able to move closer to each other, once the locking member 51 removed from the receiving portion 53. Thus, it is possible to pass, quickly and simply, from the locking position to the unlocking position, and vice versa, in particular to allow maintenance operations of the lock assembly 1.

As seen more particularly in the embodiments of Figures 2 and 5, said receiving portion 53 formed in part at the level of each of the fixing lugs 54 can be configured as a substantially cylindrical bore coming to enclose the cylindrical portion F51 of the member lock 51, when received in said receiving portion 53.

According to an embodiment illustrated by way of example in Figures 6 to 9, the fixing means 52 comprises:
- a first fixing rod T52 on which said receiving portion 53 is provided,
- a second fixing rod T52'.

Said first fixing rod T52 can be configured to be inserted into the housing 25 made in the stator 21 of the lock cylinder 2, said housing extending in a substantially longitudinal direction of the cylinder 2.

The second fixing rod T52' can be configured to be inserted into a second housing 25' also provided in the stator 21 of the lock cylinder 2, and emerging from the said longitudinal end E2 of the cylinder 2, and extending in a direction substantially parallel to the housing 25 receiving the first fixing rod T52.

Said locking member 51 may comprise a cylindrical portion F51, configured to be received in said receiving portion 53 by extending along an axis A53 substantially perpendicular to said substantially longitudinal direction of cylinder 2, when the first fixing rod T52 is positioned in slot 25.

The bore 24 may have a first end E24 opening onto an outer side wall P2 of the cylinder 2 and a second end E24' opening into the housing 25, at the level of said reception portion 53, when said first fixing rod T52 is received in said housing 25.

Said first fixing rod T52 and said locking member 51 can be configured such that the insertion of the cylindrical portion F51 of the locking member 51 into the said receiving portion 53 causes the deformation in bending of the said first rod of T52 binding so as to pass:
- an unlocking position, in which the first fixing rod T52 is spaced from the inner wall P25 of said housing 25,
- a locking position, in which the first fixing rod T52 finds itself resting against the inner wall P25 of said housing 25, in order to ensure the locking of the fixing of the lock cylinder 2 to the drive block 3.

In the locking position, the first fixing rod T52 can be deformed in bending so as to move away from the second fixing rod T52'.

In said locking position, the second fixing rod T52' can be positioned in said second housing 25'.

As described above, thanks to this advantageous arrangement of the invention, the assembly between the drive block 3 and the lock cylinder 2 proves to be particularly simple and rapid, in that it is sufficient simply to insert the locking member 51 in the bore 24 and in the receiving portion 53, so that the cylindrical portion F51 of the locking member 51 is received in said receiving portion 53, to lock the attachment between said block of drive 3 and lock cylinder 2.

In such an embodiment, and as can be seen more particularly in the example embodiment of FIG. 7, only the first fixing rod T52 can come to rest against the inner wall P25 of the housing 25, in order to ensure the stopping in translation along the longitudinal direction of the cylinder 2, of the fixing means 52 with respect to the cylinder 2, and therefore of the drive block 3 with respect to the cylinder 2, while the second fixing rod T52', in combination with the first fixing rod T52, when received respectively in the second housing 25' and in the (first) housing 25, ensure the stopping in rotation of the fixing means 5 with respect to the cylinder 2, and therefore of the drive block 3 with respect to to cylinder 2.

Such fixing rods T52, T52′ are easier to design and manufacture, and in particular make it possible to reduce the cost price of a kit and of a set of self-supporting electronic lock 1 according to the invention.

As visible in the embodiments of Figures 7 to 9, the receiving portion 53 can be made in the form of a groove extending over the entire circumference of the first fixing rod T52, and positioned so as to be opposite the bore 24, when the first fixing rod T52 is received in the housing 25.
