DESCRIPTION OF EMBODIMENTS OF THE INVENTION

Identical elements, by structure or by function, appearing in different figures keep, unless otherwise specified, the same references.

A key 1 for a motor vehicle 2, according to the invention is illustrated in Figures 1 to 9g. Key 1 is also called an identifier.

By motor vehicle is meant any type of motor vehicle.

The key 1 is illustrated in FIGS. 1 a to 1 c.

The key 1 is adapted to cooperate with a bit 12 (also illustrated in the figures) and comprises:

- a housing 10;

- a yoke 11;

- a control button 13.

The key 1 also comprises a pivot 14.

It is suitable for being open (tab 12 in the extended position p22) or closed (tab 12 in the retracted position p21).

In a nonlimiting embodiment, the key 1 is an electronic key. Namely, it is suitable for communicating remotely with a control unit (not shown) of the motor vehicle 2 in particular to allow the execution of functions f1 relating to the motor vehicle.

In nonlimiting examples, the functions f1 are:

- remote locking and / or unlocking of said motor vehicle;

- an opening and / or closing of an opening (doors, trunk, tailgate, etc.) of said motor vehicle;

- starting of said motor vehicle;

- a tire check, etc.

The bit 12 which cooperates with the key 1 is described below.

• Pan_Qtp_n_12

The bit 12 is illustrated in Figures 1 a to 1 c, 7a, 7b and 7d.

The tab 12 is adapted to fit into a lock (exterior and interior) of the motor vehicle 2 for manually unlocking / locking an opening of said motor vehicle 2, the ignition switch and the steering column.

The tab 12 is adapted to pivot from a retracted position p21 to an extended position p22.

To this end, the paneton 12 is suitable for:

- Take an exit position p22 so as to be used in a lock of the motor vehicle 2. This position is also called open key;

- take a retracted position p21 when the key 1 is not used manually to activate a lock of the motor vehicle 2. This position is also called closed key.

In a nonlimiting embodiment, the output position p22 is substantially 180 ° relative to the retracted position p21.

In the retracted position p21, the bit 12 is disposed between the two cheeks 100, 101 of the receptacle 102 of the housing 10 (described below). It abuts against a wall (not shown) which extends vertically between the two cheeks 100, 101 in a recess 104 in the receptacle 102.

The tab 12 is adapted to be fixed to the yoke 11 and is thus integral with the latter.

In a nonlimiting embodiment, the tab 12 includes a fixing orifice 121 (illustrated in FIG. 1c) adapted to receive a pin for fixing to the yoke 11 and to be placed opposite the fixing orifice 114 ( described below) in chapter 11.

The pin 12 thus pivots at the same time as the yoke 11. In particular, the nip 12 includes an end 120 adapted to fit into the cavity 113 (described below) of the yoke 11. As illustrated in FIG. 1c , this end 120 comprises a rounded part 1200 to adapt to the circular section of the housing 110 (described below) of the yoke 11.

The elements of key 1 are described in detail below.

• Bpjtier_1_0

The housing 10 is illustrated in FIGS. 1 a to 1 c.

In a nonlimiting embodiment, the housing 10 is made of a plastic material.

As illustrated in FIG. 1c, the housing 10 is formed by a receptacle 102 closed by a cover 103.

o Cover 103

As illustrated in FIG. 1c, the cover 103 of the housing 10 comprises a primary lumen 1030 through which the control pusher 13 can pass in part (in particular its upper end 133). This allows a user to access and operate said control pusher 13 by pressing it. The cover 103 is adapted to axially lock the control pusher 13. In particular, it blocks the secondary lugs 131 of the control pusher 13 (described below) when the latter is in the released position p31. It will be noted that when it is assembled to the receptacle 102, the cover 103 is adapted to press lightly on the secondary lugs 131 so that there is play between the primary lug 130 (described below) of the control pusher 13 and the yoke 11. The primary lug 130 is thus not in contact with said yoke 11 which avoids having noise during vibrations due to the motor vehicle 2 when it is in motion. Indeed, a metal contact (primary lug 130) against metal (yoke 11) makes more noise when the motor vehicle is traveling than a metal contact (secondary lugs 131) against plastic (cover 103).

o Receptacle 102 Receptacle 102 includes:

- two cheeks 100, 101;

- A lateral recess 104 between said two cheeks 100, 101;

- a housing 105 in a cheek 100.

The two cheeks 100, 101 are substantially parallel to each other and are suitable for mounting the yoke 11 on the housing 10.

The lateral recess 104 is adapted to receive the tab 12 when the latter is in a retracted position p21.

The receptacle 102 comprises a secondary light 1020 through which the control pusher 13 can pass in part (in particular its lower end 134). This secondary light 1020 is arranged opposite the primary light 1030 of the cover 103.

In a nonlimiting embodiment, the receptacle 102 comprises two notches 1021 which open onto the secondary lumen 1020 and which are adapted to each accommodate a secondary lug 131 of the control pusher 13 when the latter is in the depressed position p32 or released p31. Furthermore, the secondary light 1020 and the two notches 1021 allow the passage of the pivot 14 (described below) during its mounting in the receptacle 102, in particular the passage of the lugs 1420 of the pivot 14.

The two notches 1021 are angularly offset in the same way as the angular offset between the two secondary lugs 1020 and the two lugs 1420 of the pivot 14. In a nonlimiting embodiment, they are angularly offset by 180 ° from one 'other.

o Other elements

As illustrated in FIG. 1c, in the housing 10 is housed:

- at least one press button 106;

an electronic support 107 comprising electronic components (not shown);

- a battery 108;

- a transponder 109.

In a nonlimiting embodiment, the electronic support 107 is a PCBA printed circuit board called “Printed Circuit Board Assembly” in English.

The battery 108 is a flat battery, called a button battery. In a nonlimiting embodiment, it is arranged on one of the faces of the electronic support 107 and is adapted to supply the electronic support 107.

The transponder 109 is arranged on one of the faces of the electronic support 107 and is suitable for communicating remotely with the control unit of the motor vehicle 2. In a nonlimiting embodiment, the communication is done by the Bluetooth® protocol. Thus, in a nonlimiting embodiment, the transponder 109 is a Bluetooth® antenna. In a non-limiting variant, communication takes place by the Bluetooth Low Energy® protocol called BLE.

In a nonlimiting embodiment, the key 1 comprises a plurality of push buttons 106.

Each press button 106 makes it possible to trigger the execution of a function f1 relating to said motor vehicle. A user thus presses on said press button 106 to activate a microswitch 1060 which in combination with electronic components of the electronic support 107 will trigger the execution of the function f1. The microswitch 1060 is arranged on one of the faces of the electronic support 107. The function f1 is conventionally represented by a pictogram 1061 (illustrated in FIGS. 1a and 1b) associated disposed in a support zone of the press button 106. Such a button being known to those skilled in the art, it is not described in more detail here.

In the example illustrated in FIGS. 1a and 1b, there are three press buttons 106 adapted to respectively allow:

- remote locking of said motor vehicle;

- remote unlocking of said motor vehicle;

- an opening and / or closing of the boot or tailgate of said motor vehicle.

• Screed _1_1_

The yoke 11 is illustrated in Figures 1 a to 2c.

In a nonlimiting embodiment, the yoke 11 is made of Zamak. Zamak is an alloy that includes Zinc and aluminum. It provides good mechanical strength. The yoke 11 is thus more solid.

The yoke 11 is adapted to pivot around the control pusher 13:

- From a locked position p11 to a released position p12 so as to release the tab 12, the latter passing from its retracted position p21 to its extended position p22;

- From the released position p12 to the locked position p11 so as to return the tab 12 in the lateral recess 104 of the receptacle 102, said tab 12 passing from its extended position p22 to its retracted position p21.

The yoke 11 is integral with the bit 12. Thus, when it pivots, the latter pivots at the same time as it.

The yoke 11 comprises two external faces 11a, 11b which are substantially parallel to one another and opposite one another.

The yoke 11 is mounted in the receptacle 102 between the two cheeks 100, 101. An external face 11a is arranged opposite a cheek 100 and the other external face 11b is arranged opposite the other cheek 101.

When mounted, the yoke 11 cannot be removed from the receptacle 102 because it is retained by the pivot 14.

As illustrated in FIGS. 2a to 2c, the yoke 11 comprises:

- a cavity 113;

- a housing 110;

- two primary grooves 111 formed in the housing 110.

o Cavity 113

The cavity 113 is adapted to receive one end of the bit 12 so that the latter is fixed to said yoke 11 and is thus integral with said yoke 11. For this purpose, the yoke 11 comprises a fixing orifice 114 adapted to receive a pin (not shown) to fix the plate 12 with the yoke 11.

o Housing 110

Housing 110 is adapted to partially accommodate:

- the control button 13;

- pivot 14.

The housing 110 comprises a central axis Ax1 perpendicular to the longitudinal direction of the key 1 and to the external faces 11a, 11b. The housing 110 comprises a substantially circular cross section and opens onto the external faces 11a, 11b.

The housing 110 comprises a flange 1100 in which said primary grooves 111 are produced. The primary grooves 111 start from said flange 1100 to open into said housing 110, on the external face side 11a. The primary grooves 111 do not open on the external face side 11b. These are primary blind 111 grooves.

o Primary grooves 111

The primary grooves 111 extend along the circumference of the housing 110.

One of the primary grooves 111 is adapted to block a primary lug 130 of the control pusher 13 so as to maintain the yoke 11 in the locked position p11.

The other of the two primary grooves 111 is adapted to block a primary lug 130 of the control pusher 13 so as to maintain the yoke 11 in the released position p12 when the control pusher 13 is in the released position p31, and therefore so as to keep the bit 12 in the output position p22 when the control button 13 is in the released position p31. Indeed, without the second primary groove 111, the paneton 12 may collapse, namely not to remain in a fixed position.

In a nonlimiting embodiment, the two primary grooves 111 are arranged one opposite the other. They are thus angularly offset by 180 ° from each other.

When the control button 13 is in the depressed position p32, each primary groove 111 is adapted to alternately accommodate the primary lug 130 when the tab 12 is in the extended position p22 or in the retracted position p21. The primary lug 130 is found opposite a primary groove 111 but is not engaged in said primary groove 111 because the control pusher 13 is depressed.

In the released position p31 of the control button 13 and when the tab 12 is in the retracted position p21, the primary lug 130 will be housed in a first primary groove 111.

In the depressed position p32 of the control pusher 13, the yoke 11 is released and the paneton 12 rotate 180 ° to arrive in the output position p22. The two primary grooves 111 of the yoke 11 which has rotated the tab 12 have also rotated 180 °. The second primary groove 111 is thus found opposite the primary lug 130 which was previously engaged in said first primary groove 130. When the user releases the control button 13, the primary lug 130 will be housed in this second groove primary 111 preventing the yoke 11 from pivoting and consequently the bit 12 from collapsing. It will be noted that in the nonlimiting embodiment where the control pusher 13 comprises two primary lugs 130, each primary lug 130 is adapted to be housed alternately in one of the two primary grooves 111 of the yoke 11 when the flap 12 is in position output p22 or in the retracted position p21.

o Secondary grooves 112

In a nonlimiting embodiment, the yoke 11 further comprises two secondary grooves 112 of different width L2, L2 ’.

One of the two secondary grooves 112 is configured so as to allow the passage of said at least one primary lug 130 during the mounting of said control pusher 13 in said housing 10, and the other of the two secondary grooves 112 is configured so as to prevent the passage of said at least one primary lug 130 when the housing 10 is open, namely when the cover 103 has been removed.

The two secondary grooves 112 are configured so as to allow the pivot 14 to pass when it is mounted in the housing 10.

Thus, a primary lug 130 can be inserted into one of the two secondary grooves 112 in order to mount the control pusher 13 partially in the housing 110 of said yoke 11. The primary lug 130 will in fact first be inserted in said secondary groove 112, then after pressing the control button 13, rotation of the control button 13 and release of the latter, be housed in one of the two primary grooves

111.

The secondary grooves 112 open at their ends 112a, 112b on the external faces 11a and 11b of the yoke 11.

The first secondary groove 112 has a width L2 ′ greater than that of the primary lug 130 and the lugs 1420 of the pivot 14. When the control pusher 13 is mounted, the primary lug 130 will be inserted through the end 112a of a first secondary groove 112. When mounting the pivot 14, the latter will be inserted in part (via its lugs 1420) by the same end 112a until going to the other end 112b of the first secondary groove 112 .

The second secondary groove 112 comprises a width L2 less than that L1 of the primary lug 130. It is adapted to block a primary lug 130 in translation so as to avoid disassembly of said control pusher 13 outside said receptacle 102 when said housing 10 is open.

In particular, it retains the primary lug 130 in axial translation when it passes over said primary lug 130, namely:

- a) when the yoke 11 passes from a locked position p11 (bit 12 in the retracted position p21) to a released position p12 (bit 12 in the extended position p22). It will be noted that in this case, the second secondary groove 112 passes over the primary lug 130 when it rotates 90 ° relative to the locked position p11 of the yoke 11 clockwise;

- b) when the yoke 11 passes from a released position p12 (bit 12 in the extended position p22) to a blocked p11 (bit 12 in the retracted position p21). It will be noted that in this case, the second secondary groove 112 passes over the primary lug 130 when it rotates 90 ° relative to the released position p12 of the yoke 11 counterclockwise.

The primary lug 130 is blocked in translation by said second secondary groove 112 so that the control pusher 13 cannot be removed when the housing 10 is open. The primary lug 130 cannot thus pass through the second secondary groove 112 and exit from said second secondary groove 112. Thus, the control pusher 13 cannot be removed from the receptacle 102 of the housing 10 when the latter is open, namely when the cover 103 has been removed.

It will be noted that in the cases of use of the key 1, namely in the cases a) and b) mentioned above, the first secondary groove 112 (of width L2 ') will not pass over the lug primary 130. The latter will rotate 180 ° clockwise (in case a) or counterclockwise (in case b) but never pass over the primary lug 130. In the two cases, it will always be offset by 90 ° relative to the primary lug 130.

It will be noted that in the case where there are two primary lugs 130, the first secondary groove 112 (of greater width L2 ′) can pass over one of the primary lugs 130. However, at the same time, the second secondary groove 112 (of width L2 less) will pass over the other primary lug 130, thus preventing the passage of the latter. The second secondary groove 112 will thus block this second primary lug 130 preventing the control pusher 13 from being removed from the housing 10 by a user when the cover 103 is removed.

In a nonlimiting embodiment, the two secondary grooves 112 are arranged one opposite the other, that is to say they are angularly offset from each other by substantially 180 °. In a nonlimiting embodiment, a primary groove 111 is disposed substantially at 90 ° relative to a secondary groove 112.

This makes it possible to have guide zones 115 in the yoke 11 of substantially equal size and to have a guide for the control pusher 13 in the housing 110 of said uniform yoke 11. As illustrated in FIG. 2b, the guide zones 115 are formed by four arcs of a circle. They are located on the inner circumference of the flange 1100 as illustrated in FIG. 2c. In the nonlimiting embodiment illustrated, an arc 115 is thus offset by 90 ° relative to an adjacent arc.

In a nonlimiting embodiment, the secondary groove 112 is offset by 45 ° relative to the longitudinal axis of the plate 12. This makes it possible not to hinder the fixing of the plate 12 on the yoke 11.

As illustrated in FIGS. 9a to 9f, said yoke 11 is adapted to be disposed substantially at 90 ° relative to a locked position p11 so as to allow the insertion in part of said control pusher 13 in its housing 110 and of said at least primary lug 130 in one of the two secondary grooves 112. This position is an assembly position between the two cheeks 100, 101 of said housing 10. In particular this assembly position p13 allows the insertion, on the one hand, of said pivot 14 in its housing 110 and its lugs 1420 in these two secondary grooves 112, and on the other hand, the insertion of said control pusher 13 in its housing 110 and of said at least primary lug 130 in its first secondary groove 112.

Furthermore, as illustrated in FIG. 9g, said yoke 11 is adapted to be rotated relative to its assembly position p13 to arrive at its assembled position so as to offset said at least primary lug 130 relative to the two secondary grooves 112 and to allow insertion into a primary groove 111 when the control button 13 is subsequently released. Note that the assembled position corresponds to the locked position p11 of the key.

In a nonlimiting embodiment illustrated, said rotation is carried out clockwise. The rotation includes a sufficient angle so that once the bit 12 mounted on the key 1, it can no longer return to the assembly position p13. Indeed, once mounted, the tab 11 abuts against the wall which extends between the two cheeks 100, 101 of the receptacle 102 and thus prevents the yoke 11 from rotating counterclockwise. The latter can no longer move from its assembled position p11 to its assembly position p13.

In a nonlimiting embodiment illustrated, the rotation relative to its assembly position p13 is substantially 90 °. The yoke 11 is simpler to assemble with this angle.

Note that in other nonlimiting embodiments, a rotation of substantially 10 ° could be performed or more than 90 °.

The goal is that the assembly position p13 can no longer be possible once the tab 12 is mounted.

The control button 13 is illustrated in Figures 1a to 1c, and 3a, 3b, 5 to 8b.

In a nonlimiting embodiment, the control pusher 13 is made of Zamak.

It has a substantially cylindrical shape and has a circular section.

It is hollow so as to accommodate a spring 15.

The control button 13 includes:

- An upper end 133 adapted to extend projecting from the housing 110 of the yoke 11 and the cover 103 passing through the primary lumen 1030 of the latter. This upper end 133 is closed and has an end face 135 serving to support a user's finger.

- An opposite lower end 134 adapted to be housed in the housing 110 of the yoke 11. This end 134 is open. The control pusher 13 is thus partially inserted into said housing 110 of said yoke 11;

The control push-button 13 is non-pivoting. It is not integral with the yoke 11, that is to say it does not pivot when the latter pivots.

The control button 13 is suitable for:

- Take a pressed position p32 so as to release in rotation said yoke 11. In its pressed position p32, the control button 13 is pressed. Pressing a finger of a user pushes the control button 13;

- Take a relaxed position p31 so as to block said clevis in rotation 11. The user no longer presses the control button 13.

Thus, the control button 13 is adapted to perform only a translational movement. In addition, this translational movement is an axial movement along the central axis Ax1 of the yoke 11.

The paneton 12 being integral with the yoke 11, in a nonlimiting embodiment, said control pusher 13 is further adapted for:

- block said tab 12 in the retracted position p21 or in the extended position p22 when it is in the relaxed position p31;

- release said tab 12 in the extended position p22 when it passes from its relaxed position p31 to its depressed position p32.

o Primary pin 130

In a nonlimiting embodiment, the control pusher 13 comprises at least one primary lug 130.

The primary lug 130 projects from the upper end 133 of the control pusher 13.

It is suitable for:

- disengage from one of the primary grooves 111 when said control pusher 13 is in the depressed position p32 so as to release said yoke 11 in rotation so that it can gain its released position p12 as illustrated in FIG. 7a. In the depressed position p32, the primary lug 130 thus slides out of said primary groove 111 and the yoke is no longer retained by the primary lug 130 and can rotate around the control pusher 13 to its released position p12 . When the yoke 11 is thus in the released position p12 and the control pusher 13 in the depressed position p32, the primary lug 130 is opposite the other primary groove 111 as illustrated in FIG. 7d. As can be seen in FIG. 7d, the primary lug 130 is not engaged in said other primary groove 111, as long as the control pusher 13 is in the depressed position p32;

- Be engaged in one of the primary grooves 111 of said yoke 11 when said control pusher 13 is in the released position p31 so as to block in rotation said yoke 11 as illustrated in FIGS. 8b and 8c. In FIGS. 8b and 8c, said primary groove is the furthest from the end 120 of the bit 12. Said yoke 11 is thus maintained in the locked position p11;

- when the yoke 11 is in the released position p12, engage in the other primary groove 111 when the control pusher 13 is in the released position p31 as illustrated in FIGS. 7b and 7c. The other primary groove 111 thus makes it possible to maintain the position of the yoke 11 in its released position p12 when the control pusher 13 is in the released position p31.

Thus, as in the nonlimiting example illustrated in FIGS. 7a to 8c, it will be noted that the first primary groove 111 which blocks the primary lug 130 when the yoke 11 is in the locked position p11 is the one which is furthest from the end 120 of the bit 12, and the second primary groove 111 which blocks the primary lug 130 such that the yoke 11 is in the released position p12 is that closest to the end 120 of the bit 12.

The control pusher 13 passes from its relaxed position p31 to its depressed position p32 by performing an axial translation along the central axis Ax1 of the yoke 11, and this downwards. The primary lug 130 slides axially from top to bottom.

The control button 13 passes from its depressed position p32 to its relaxed position p31 by performing an axial translation along the central axis Ax1 of the yoke 11, and this upwards. The primary lug 130 slides axially from bottom to top. In this case, the primary lug 130 is stopped in its axial translation by the contact between the secondary lug 131 and the cover 103. It is not in contact with the yoke 11 and more particularly with the primary grooves 111 of the flange 1100. As described above, there is a clearance between the primary lug 130 and said yoke 11, more particularly with said primary grooves 111.

In a nonlimiting variant embodiment not illustrated, the control pusher 13 comprises two primary pins 130. This makes it possible to increase the mechanical resistance during stresses in the life of the product which is the key 1. In a nonlimiting embodiment , the two primary pins are angularly offset from each other by substantially 180 °. They will thus alternately be blocked by the two primary grooves 111 when the control pusher 13 is in the released position p31 and when the yoke 11 is in the blocked position p11 or in the released position p12.

As described above, the primary lug 130 comprises a width L1 less than that L2 'of one of the two secondary grooves 112 and a width L1 greater than that L2 of the other of the two secondary grooves 112. Thus, it is suitable for be blocked in translation by the other of the two secondary grooves 112 so as to avoid disassembly of said control button 13 outside said receptacle 102 when said housing 10 is open.

Note that when a user removes the cover 103 to change the battery 108:

- If it does not press the control push-button 13, there is no longer any pressure on the secondary lug 131 which causes the presence of play between the primary lug 130 and the yoke 11. The spring 15 will put in contact with the primary lug 130 with the yoke 11. The primary lug 130 is therefore blocked by the yoke 11, in particular by a primary groove 111. The control pusher 13 is consequently blocked in translation by the yoke 11.

- If the user presses the press button 13, the primary lug 130 leaves the primary groove 111 so that the yoke 11 is released and pivots counterclockwise. In this case, the secondary groove 112 passes over the primary lug 130 when the yoke 11 pivots 90 ° before pivoting completely up to 180 °. Thanks to the fact that the primary lug 130 has a width L1 greater than the width L2 of the secondary groove 112, this prevents the primary lug 130 from passing through this secondary groove 112 and that the control pusher 13 cannot be removed from receptacle 102 when housing 10 is opened. Thus, the control button 13 cannot be removed by a user. Thus, the primary lug 130 is blocked in translation by one of the two secondary grooves 112 (that of width L2 less) so as to avoid disassembly of said control button 13 outside said receptacle 102 when said housing 10 is open.

- it is the same if the user does not press the press button 13 but turns the blade 12 so as to move it from an extended position p22 to its retracted position p21, the secondary groove 112 passes over the primary lug 130 when the yoke 11 pivots 90 ° before pivoting completely up to 180 °.

o Secondary pin 131

As illustrated in FIGS. 3a and 3b for example, in a nonlimiting embodiment, the control pusher 13 comprises at least one secondary lug 131.

The secondary lug 131 extends projecting from the upper end 133 of the control pusher 13 set back from the terminal face 135 thereof. Secondary lug 131 is suitable for:

- block in rotation the control button 13;

- Guide the control button 13 in translation.

For this purpose, the secondary lug 131 is suitable for:

- be engaged in the notch 1021 of the receptacle 102, notch 1021 which opens onto the lumen 1020 of the receptacle 102 when the control pusher 13 is in its released position p31;

- remained engaged in said notch 1021 when the control button 13 is in its depressed position p32.

The control push-button 13 cannot thus pivot. It can only perform an axial translational movement. The secondary lug 131 always remains in the notch 1021 whether the control button 13 is in the released position p31 or in the depressed position p32.

Thus, when the yoke 11 is released in rotation, it cannot rotate the control pusher 13.

In the same way as for the primary lug 130, the secondary lug 131 thus slides axially from top to bottom when the control pusher 13 passes from its released position p31 to its depressed position. The secondary lug 131 thus slides axially from bottom to top when the control button 13 passes from its depressed position p32 to its relaxed position p31.

In a nonlimiting variant embodiment not illustrated, the control pusher 13 comprises two secondary pins 131. This makes it possible to increase the mechanical resistance during stresses in the life of the product which is the key 1. In a nonlimiting embodiment , the two secondary pins 131 are angularly offset from each other by substantially 180 °. This makes it possible not to feel any hard point during the rotation of the yoke 11.

In a nonlimiting embodiment, one of the two secondary lugs 131 is substantially aligned vertically with a primary lug 130. This makes it possible to optimize the space available in the key 1.

o Slot 132

In a nonlimiting embodiment illustrated in FIG. 3b, the control pusher 13 further comprises a slot 132 adapted to receive an end 150 (illustrated in FIG. 1c) of the spring 15 described below and to immobilize this end 150 in rotation relative to said control button 13.

The control button 13 and the pivot 14 described below define a pivot axis of the yoke 11 relative to the housing 10. This pivot axis coincides with the central axis Ax1 of the yoke 11.

• Pivot 14

The pivot 14 is illustrated in FIGS. 1 c, 4 to 6, 7b, 7d and 8b.

The pivot 14 is integral with said yoke 11 and is adapted to be driven in rotation by the spring 15. The pivot 14 is thus adapted to rotate the yoke 11.11 is also adapted to prevent the yoke 11 from coming out of the receptacle 102.

It is hollow so as to receive the spring 15.

As illustrated in FIG. 4a, the pivot 14 includes:

- A slot 140 adapted to receive one end 151 of the spring 15;

a body 143, part of which 141 is adapted to be housed in the housing 105 of the cheek 100 of the receptacle 102, and a part 142 is adapted to be housed in the housing 110 of the yoke 11.

The body 143 has a substantially cylindrical shape and has a circular section.

The slot 140 is adapted to immobilize this end 151 in rotation relative to the pivot 14.

In a nonlimiting embodiment, the part 141 comprises a planar external face 1410 which is not in contact with the flat surface of the bottom of the housing 105. There is a clearance. The part 141 of the body 143 forms with the housing 105 a stop opposing the extraction of the yoke 11 from the receptacle 102. The pivot 14 is pressed into the bottom of the housing 105 by the spring 15. Thus, the yoke 11 cannot come out of the receptacle 102 when the pivot 14 is mounted in the housing 10.

The pivot 14 is adapted to be inserted partly in the two secondary grooves 112. More particularly, in a nonlimiting embodiment, the part 142 of the body 143 comprises two lugs 1420 (illustrated in FIGS. 4a and 4b) which are 'extend laterally projecting from the pivot 14 and which are adapted to be housed respectively in the two secondary grooves 112 of the yoke 11. The two pins 1420 are angularly offset relative to each other. In a nonlimiting embodiment, they are offset by 180 °. Thus, each lug 1420 comprises a size (width, length) smaller than that of the respective secondary groove 112 into which it must be inserted. The two pins 1420 each comprise a flange 1421 adapted to come to rest on the yoke 11 when the pivot 14 is mounted in the housing 110 of the yoke 11. More particularly, each flange 1421 comprises a lower part 1422 which is adapted to be in contact with the bearing surfaces 1122 of the yoke 11 as illustrated in FIG. 4b.

The two pins 1420 are adapted to abut against the two secondary grooves 112 when the spring 15 works in torsion. Thus, the yoke 11 is rotated by the pivot 14.

• RessQrt_1_5

The spring 15 is illustrated in Figures 1c, 5, 6, 7b, 7d and 8b.

The spring 15 is a helical spring which is arranged to work in compression.

It comprises two ends 150 and 151 immobilized respectively in rotation in the control pusher 13 and in the pivot 14.

When the yoke 11 is in the locked position p11 (pawl 12 in the retracted position p21), the spring 15 has been subjected to a torsion of substantially 180 ° relative to its rest state.

The spring 15 is thus arranged to work in torsion for:

- Keep the yoke 11 in abutment in the receptacle 102 when the control pusher 13 is mounted;

- return the yoke 11 to its released position p12 when the control pusher 13 is in the depressed position p32 and keep the primary lug 130 in abutment in one of the primary grooves 111 when the control pusher 13 is again in the released position p31;

- exert pressure on the control button 13 to return it to the relaxed position p31 when there is no more pressure from the user on said control button 13. The spring 15 is thus adapted to translate axially the control pusher 13 from its depressed position p32 to its relaxed position p31.

• Assembly

FIGS. 9a to 9g illustrate a method of mounting P of said key 1.

As illustrated in Figures 9a and 9b, the mounting method P comprises a first step of positioning said yoke 11 in an assembly position p13 between the two cheeks 100, 101 of the receptacle 102 of said housing 10. Said yoke 11 is positioned in an assembly position p13 angularly offset from its locked position p11 for mounting said control pusher 13 in said receptacle 102 of said housing 10. Thus, in a nonlimiting example, its assembly position p13 is offset angularly substantially 90 ° relative to its locked position p11.

As illustrated in FIGS. 9c and 9d, the mounting method P comprises a second step of mounting the pivot 14 in the receptacle 102 of the housing 10 comprising the insertion of its lugs 1420 in the secondary grooves 112 of the yoke 11 and of its body 143 in the housing 110 of the yoke 11 and in the housing 105 of the receptacle 102. The pivot 14 is pressed to the bottom of the housing 105 of the receptacle 102 so that its external face 1410 touches said bottom and the pins 1420 are supported on the bearing surfaces 1122 of the yoke 11 via their lower part 1422.

The mounting method P comprises a third step (not illustrated) for hooking the spring 15 to the control pusher 13 by one of its ends 150 via the slot 132 of the control pusher 13. The spring 15 is bandaged when the control pusher 13 is mounted in the housing 10. It thus undergoes a torsion of substantially 90 °. It will be noted that its other end 151 is introduced into the slot 140 of the pivot 14 by placing the control button 13 above the pivot 14 and the yoke 11. In a nonlimiting example, when it is at rest, the spring 15 includes a size of 19mm (millimeters). In its compressed state, it includes a size of 10mm.

As illustrated in FIGS. 9e and 9f, the mounting method P comprises a fourth step of mounting the control button 13 in the housing 10. This fourth step includes sub-steps comprising:

- An arrangement of the control push-button 13 above the receptacle 102 so that its primary (s) 130 and secondary lugs 131 are opposite the notches 1021 of the receptacle 102;

- An axial insertion of the control button 13 in the secondary lumen 1020 of the receptacle 102 so that the primary lug 130 is inserted into a notch 1021 then thereafter the secondary lugs 131 in the notches 1021;

a partial insertion of the control pusher 13 into the housing 110 of said yoke 11 and at least one primary lug 130 of the control pusher 13 is inserted in one of the two secondary grooves 112 of said yoke 11.

At the end of its travel, namely when its end 134 touches the pivot 14, as illustrated in FIG. 9g, the mounting method P comprises a fifth step of rotation of said yoke 11 to reach its locked position p11 so that said at least primary lug 130 is offset from the two secondary grooves 112 of said yoke 11 and can be engaged in a primary groove 111 of said yoke 11. The rotation is substantially 90 ° relative to its assembly position p13. The spring 15 is thus twisted substantially 180 ° in a nonlimiting example. As a reminder, the spring 15 was previously bandaged 90 ° previously. It is thus pre-stressed to the maximum. Rotation is done clockwise. This makes it possible to give the spring 15 the prestress in the direction of rotation of the yoke 11.

It will be noted that at the end of travel of the control pusher 13, the primary lug 130 is offset axially with respect to the flange 1100 of the yoke 11 so that when the yoke 11 is rotated, the primary lug 130 does not block said rotation coming into abutment against said flange 1100, namely does not remain engaged in a primary groove 111. The mounting method P comprises in a sixth step (not shown) the release of the control pusher 13 so that the primary lug 130 engages in the primary groove 111 which is furthest from the end 120 of the bit 12 and thus blocks the yoke 11 in rotation.

It will be noted that the fixing of the plate 12 to said yoke 11 is carried out subsequently, conventionally by the end customer, namely the car manufacturer. One end of the bit 12 is inserted into the cavity 113 of the yoke 11 provided for this purpose and is fixed to the yoke 11 by means of a pin inserted in the fixing orifice 114 of the yoke 11 and in the orifice of fixing 121 of the bit 12.

Of course, the description of the invention is not limited to the embodiments described above.

Thus, in a nonlimiting embodiment, the yoke 11 can be made of a plastic material or of metal.

Thus, in a nonlimiting embodiment, the control button 13 can be made of a plastic material or metal.

Thus, the invention described has the following advantages in particular:

- It allows the battery 108 of the key 1 to be changed without the user being able to remove the control button 13 from the housing 10;

- It allows to have a yoke release system 11 without having a rotary control button 13. It is an alternative solution to a key with a control button integral with the yoke and therefore rotatable.
