Description

The invention relates to the technical field of locks, intended, in particular, for installation in locking mechanisms of opening parts of a motor vehicle.

The classic lock contains a stationary body, called a stator, mounted stationary in the locking mechanism and / or in the opening part, a generally cylindrical rotor, seated in a stationary body and having a borehole for key insertion. A set of radially movable plates blocks or unlocks the rotation of the rotor relative to the stationary body. When the key is inserted into the bore of the rotor, the plates move and the rotor can only rotate if the key is correct.

After that, the rotation of the rotor leads to the unblocking of the locking mechanism.

The rotor is adapted to be connected to a door lock device, for example, by means of a cable, such as a Bowden cable, or by means of a rod at the level of a connecting element, such as a lever, adapted to attach the first end of the cable or rod to it. This cable or this rod is fixed with its second end, opposite to the first end, on the door locking device in such a way that rotation of the rotor with the key leads to the unlocking of the locking device.

A lock of this type is usually installed in the door handle bracket or directly in the panel of the opening part.

During the installation of the lock directly in the panel of the opening part, the connection is made from the outside of the opening part, that is, from the side facing the outside of the passenger compartment of the vehicle.

When the lock is installed in the handle bracket at the level of the slot for accommodating the lock, such as a bracket, the connection can be made from the inside of the opening part, that is, from the side facing the interior of the vehicle, or from the side facing outward of the opening part.

However, when the lock is installed in the handle arm and on the side facing outward of the opening portion, the thickness of the clip forces the lock to be installed along an axis parallel to the longitudinal axis of the clip. For this reason, the lever of the known lock, which has a shape that does not allow it to pass through the bracket, can be connected to the rotor only after the lock is installed in the bracket of the bracket.

Consequently, the assembly of the lock on the opening part is difficult and requires a certain number of steps, which leads to an increase in assembly time.

In addition, the number of parts included in the lock that require machining increases accordingly.

Finally, it is important to correctly connect the appropriate arm to the rotor depending on the opening part on which it will be mounted. Indeed, the configuration of the rotor arm will differ depending on whether it is installed on the right or left door of a motor vehicle.

The object of the invention is to eliminate at least one of the above disadvantages by creating a lock for an opening part of a motor vehicle, comprising a rotor located inside the stator, wherein the rotor is rotatable relative to the stator, and a lever rigidly connected to the rotor, wherein the lever comprises a lever base, rigidly connected to the rotor, and an elongated part of the lever made with the possibility of movement relative to the base of the lever between the insertion position, in which the elongated part of the lever is located in the stator envelope, and the fastening position, in which the elongated part of the lever protrudes with respect to the stator envelope ...

The dimension of the stator should be understood as the lateral dimensions of the stator transversely to the axis of extension of the lock. In other words, the axis of the extension can correspond to the axis of insertion of the lock into the seat, in particular into the seat of the handle bracket. The dimensions correspond to the dimensions of the lock transversely to the axis of insertion, in particular, perpendicular to this axis. It can also be considered that the dimensions of the lock correspond to the projection of the stator onto the transverse plane, in particular, perpendicular to the direction of insertion.

In the insertion position, the lock can be inserted into the socket in the direction of insertion, with the elongated part enclosed in the stator, and the socket is made with the possibility of passing through it said stator. When the lock is in place, the elongated portion passes through the socket and is outside the socket. Thereafter, the lengthened part of the arm can be moved to a fastening position in which the arm protrudes in relation to the dimensions of the stator.

Since the lever is rigidly connected to the rotor, this allows the use of only one part, in contrast to the known locks, where two parts are joined to obtain a lock. Using only one part also saves time when installing the lock.

According to an embodiment, the lengthened portion of the lever is configured to be positioned in the insertion position of the lock so as to form an angle of less than 30 ° with the axis of the extension of the lock.

This angle between the axis of the extension of the lock and the elongated portion of the lever allows the entire lock to be inserted through its seat in only one step.

According to an embodiment, the lengthened part of the lever is configured to be positioned in the attachment position so as to form an angle with the extension axis of the lock of 60 ° to 120 °.

According to an embodiment, the rotor is rotatable about an axis of rotation parallel to the extension axis of the lock, and the elongated portion of the lever is pivotally connected to the stationary base of the lever about an axis transverse to the axis of rotation of the rotor.

According to an embodiment, the rotor comprises a first end adapted to receive a key therein and a second end opposite to the first end adapted to receive a lever base.

According to an embodiment, the lengthened portion of the arm comprises an attachment of the elongated portion, and the arm base comprises an attachment of the arm base, the attachment of the elongated portion being adapted to cooperate with the attachment of the arm base in the attachment position.

According to an embodiment, the arm base attachment is configured to cooperate with the attachment of the extended arm portion in the first arm attachment position and in the second arm attachment position.

According to an embodiment, the attachment of the lengthened arm portion, respectively, the attachment of the arm base comprises at least one main hole, and the attachment of the arm base, respectively, the attachment of the elongated arm portion comprises at least one main latch, wherein said at least one main hole is formed with snap-in on the main latch.

According to an embodiment, the lengthened portion of the arm is pivotally mounted relative to the arm base by means of a hinge.

In an embodiment, the hinge is located along the diameter of the arm base.

In an embodiment, the arm base is shaped and dimensioned less than or equal to the stator diameter.

In an embodiment, the arm base attachment comprises two attachment points, wherein the attachment of the extended arm portion can be secured to one or the other of the attachment sites. In particular, the seats are located on both sides of the hinge. In particular, the locations are located symmetrically about the hinge. According to an embodiment, the locations comprise latches or holes.

According to an embodiment, the attachment of the lengthened part of the lever, respectively, the attachment of the lever base comprises at least two additional holes, each of the two additional holes located on two sides of the specified at least one main hole, and the attachment of the base of the lever, respectively, the attachment of the elongated part of the lever contains at least two additional latches, and each additional hole can be latched onto each corresponding additional latch.

In an embodiment, the elongated portion of the arm comprises a free end having an opening for a cable or rod to pass.

The problem posed by the invention is also solved in the method of connecting the claimed lock with the opening part of the vehicle, which includes the following steps:

- insertion of a lock into a slot, such as a handle bracket, or insertion of a lock directly into the panel of the opening part using a fastening ring,

- snapping of the lengthened part of the lever on the base of the lever.

The problem posed by the invention is also solved in a unit that includes the claimed lock and a door lock device, and in which, at the level of the elongated part of the lever, the lock is connected to the door lock device by means of a pull rod or cable, such as a Bowden cable.

One of the ends of the lock 1 contains a borehole 5 for inserting a key made with the possibility of driving the rotor 2.

The other end of the lock 1, that is, the end of the rotor 2, which is farthest from the key insertion hole 5, is made with the possibility of installing a lever 4 on it.

Before installing the lock 1 on the bracket of the bracket 6 of the vehicle handle, the lock 1 is placed outside the opening part of the vehicle and, therefore, the bracket 6, the side of which is facing the outside of the vehicle interior, and the lever is located from the inside of the opening part of the vehicle and, therefore, the bracket 6, side which faces the interior of the vehicle.

The lever 4 comprises a first part 7 of a circular shape, adapted to be attached to the rotor 2, and a second part 8 of a substantially triangular shape, located radially and perpendicular to the longitudinal axis A of the extension of the lock 1.

Of course, the triangular shape of the first portion 7 of the lever 4 is not limiting. Indeed, this shape can also be, for example, square or round.

The second part 8 of the lever 4 contains an opening 9 for accommodating the locking / unlocking system of the door locking device.

In the description of the following figures, "latch" should be understood as an elastic element made with the possibility of compression by the wall during movement and with the possibility of straightening to restore its original shape when the element enters its intended hole, while the element can be removed from the hole by compression and moving in the opposite direction.

FIG. 2A shows the claimed lock 100. This lock 100 of a substantially cylindrical shape, located along the longitudinal axis A of the extension, comprises, like the prior art lock 1 shown in FIG. 1, a rotor 2, fitted in a stator 3 and made with the possibility of rotation relative to the stator 3 around an axis of rotation parallel to the longitudinal axis A of the extension of the lock 100.

Of course, the cylindrical shape of the lock 100 is not limiting. Indeed, this shape can also be, for example, substantially square or round.

The rotor 2 is bounded by the first end, in which the borehole 5 is made for inserting the key, made with the possibility of driving the rotor 2, and by the second end 10, opposite the first end.

In contrast to the known lock 1, the lock 100 according to the first embodiment of the invention comprises a lever 40 of a substantially triangular shape, rigidly connected to the lock 100 and in particular to the rotor 2.

Of course, the triangular shape of the arm 40 is not limiting. Indeed, this shape can also be, for example, square or round.

The arm 40 comprises an arm base 70, which is secured to the second end 10 of the rotor 2, and an elongated arm portion 80, which protrudes from the arm base 70.

The arm base 70 has a shape and dimensions less than or equal to the stator 3, into which it is inserted so that the arm base 70 is within the stator 3.

The extended arm portion 80 is pivotally connected to the arm base 70 by means of a hinge 11 located along the diameter of the arm base 70.

In this figure, the elongated portion 80 of the lever is shown in the insertion position. Indeed, the elongated arm portion 80 has a projection parallel to the extension axis A of the lock 100, with the elongated arm portion 80 being within the stator 3.

Of course, in the insertion position of the lock 100, the lengthened portion 80 of the lever may form an angle of less than 30 ° with the extension axis A of the lock 100.

The elongated arm portion 80 comprises an elongate arm attachment that, in this exemplary embodiment, includes a rectangular main opening 12 located at the center of the base of the elongated arm portion 80.

It should be noted that the rectangular shape of the main opening 12 is only an example of an embodiment of the invention. Any other geometric shape can be envisaged.

The elongated arm portion 80 also has two additional circular holes 13a and 13b located on both sides of the main hole 12. Of course, the circular shape of the additional holes 13a and 13b does not limit the invention.

Finally, the elongated lever portion 80 comprises an opening 9 located at the apex of this elongated lever portion 80 and adapted to receive a locking / unlocking system for a door lock, such as a cable or pull rod, for example.

The arm base 70 comprises a lever base mount which, in this exemplary embodiment, includes a protruding main latch 14 configured to extend through the main opening 12 to block any movement of the elongated arm portion 80.

Of course, the shape of the main latch 14 matches the shape of the main opening 12 so that the main latch 14 can be snapped into the main opening 12.

The arm base 70 also includes two protruding secondary latches 15a and 15b located on either side of the main latch 14. Each secondary latch 15a and 15b is configured to pass through a respective secondary opening 13a and 13b to block any movement of the extension arm 80.

Of course, the main latch 14 and the secondary latches 15a and 15b may be located on the arm extension 80, and the main hole 12 and the secondary holes 13a and 13b may be located on the arm base 70.

FIG. 2B shows a lock 100 in which an elongated portion 80 of the arm 40 is latched onto the base 70 of the arm 40.

Indeed, in this exemplary embodiment, the arm elongated portion 80 is in an attachment position in which the arm elongated portion 80 has a projection perpendicular to the extension axis A of the lock 100, the arm elongate portion 80 protruding relative to the stator 3. Of course, the elongated arm portion 80 of the lever can be in the attachment position so as to form an angle of 60 to 120 ° with the axis A of the extension of the lock 100.

The main hole 12 of the extension arm portion 80 is latched onto the main latch 14 of the base 70 of the lever 40, and the additional holes 13a and 13b are latched onto the respective additional latches 15a and 15b.

In this position, that is, when the arm extension 80 is snapped onto the base 70 of the arm 40, the arm extension 80 is radially and perpendicular to the extension axis A of the lock 100.

FIG. 3 shows a lever 400 according to a second embodiment of the invention. In contrast to the lever 40 of the first embodiment, the lever base 70 has a lever base fastening consisting of two main latches 14 located at the level of the two fastening points, that is, on both sides of the hinge 11. The main opening 12 is configured to snap into one or the other of the main latches 14.

The arm base 70 also includes four additional latches 15a, 15b, 15c and 15d. Additional latches 15a, 15b, 15c and 15d are distributed in pairs on both sides of the hinge 11, that is, additional latches 15a and 15b are located on one side of the hinge 11, and additional latches 15c and 15d are located on the other side of the hinge 11.

The additional holes 13a and 13b are configured to snap onto the respective additional latches 15a and 15b in the first lever attachment position 400 or to the corresponding additional latches 15c and 15d in the second lever attachment position 400.

The arm base attachment, that is, in this embodiment, the main latches 14 and additional latches 15a, 15b, 15c and 15d are distributed on both sides of the hinge 11, as described above, symmetrically about the hinge 11.

FIG. 4 shows the lock 100 before it is installed in the bracket of the arm 6 of the vehicle handle.

In contrast to the known lock 1 described with reference to FIG. 1, the lever 40, 400 is rigidly connected to the rotor 2 even before the lock 100 is installed in the bracket 6, when it is installed outside the opening part and, therefore, outside the bracket 6, the side of which faces the outside of the vehicle interior.

The following paragraphs describe the operation of the present invention in comparison with the prior art and with reference to the figures.

In the known solution shown in FIG. 1, the installation of the lock 1 is carried out outside the opening part of the vehicle, that is, from the side of the bracket 6 facing the outside of the vehicle interior.

In this version of the installation of the lock 1, it is impossible to install this lock 1 together with the lever 4, rigidly connected to the rotor 2. Indeed, the thickness of the bracket, provided for the placement of the lock 1, forces the lock 1 to be installed parallel to the axis of the extension of the bracket. Therefore, the lever 4 and, in particular, the second part 8 of the triangular-shaped lever, located radially and perpendicular to the longitudinal axis A of the extension of the lock 1, cannot pass through the bracket of the bracket 6.

For this reason, the rotor 2 and the lever 4 are connected after the introduction of the lock 1 containing the stator 3 and the rotor 2 into the bracket of the bracket 6. Indeed, the lock 1 containing the stator 3 and the rotor 2 is inserted into the bracket from the side of the bracket 6 facing the outside of the passenger compartment. means, then the lever 4 is attached to the rotor 2 at the level of its end opposite to the end on which the borehole 5 is located, and from the side of the bracket facing the passenger compartment of the vehicle.

Thus, in the known solution, the lock 1 consists of two separate unconnected parts, and to install the lock 1 in the bracket of the bracket 6, it is necessary to carry out many steps in order to connect the door lock device to the handle using the door lock / unlock element.

In the present invention, as shown in FIG. 4, the lock 100 contains a stator 3, as well as a lever 40, 400 rigidly connected to the rotor 2 before installing the lock 100 in the bracket of the bracket 6. According to the same mounting method as in the above-mentioned known solution, the elongated part 80 of the lever is positioned along the longitudinal axis And the extension of the lock is 100, as well as the bracket of the bracket 6.

Indeed, the lock 100 can pass through the shackle and be in the correct position in the shackle without the need to disconnect the lever 40, 400 from the rotor 2.

Once the lock 100 has been positioned in the bracket, the lengthened lever portion 80 is rotated so that it snaps into the base 70 of the lever 40 and so that once it is snapped in, any movement of the lengthened lever portion 80 is blocked.

In the case where the rotor 2 is equipped with an arm 40 shown in FIG. 2A and 2B, that is, the lever 40 according to the first embodiment of the invention, the lever 40 needs to be positioned correctly depending on the opening part on which the lock 100 is installed.

For example, if the lock 100 is installed on the driver's side opening portion, the extended lever portion 80 will snap in the direction in which the main latch 14 and the additional latches 15a and 15b are located to lock / unlock the door lock when a pull rod or cable connects the lock 100. with a door lock.

If the same lock 100 is installed in the same position on the opening part, but this time on the passenger side, which is opposite the opening part on the driver's side, a malfunction of the locking / unlocking system of the door lock device will occur when a rod or cable connects the lock 100 with a door lock. Indeed, the lengthened arm portion 80 that snaps into the base 70 of the arm 40 will not be positioned correctly for proper locking / unlocking of the door lock.

Therefore, in the second embodiment, the lever 400 includes two main latches 14 and four additional latches 15a, 15b, 15c and 15d, distributed on two sides and symmetrically about the hinge 11.

This allows the arm 400 to be the same for each opening part of the vehicle.

After snapping the elongated part 80 of the lever on the base 70 of the lever 40, a rod or cable, for example, of the Bowden cable type, connects the door lock with the lock 100 and, in particular, with the elongated part 80 of the lever 40, 400 through an opening 9 made in the top of the elongated arm portions 80 are generally triangular in shape.

Thus, the method of connecting the lock 100 comprises two steps, namely, inserting the lock 100 into a slot, such as the bracket of the handle bracket 6, and snapping the elongated portion 80 of the lever 40, 400 onto the base 70 of the lever 40, 400.

It should be noted that in the case of installing the lock 100 directly in the panel of the opening part, the first step in the connection method will be to insert the lock 100 directly into the panel of the opening part using the fastening ring.

Of course, the lock 100 can be used, for example, in the case of opening parts such as side doors, trunk lids or rear doors.
