Abstract

The switch includes a ring (300) on a hand lever (500) which rotates about its axis (302) to turn an eccentric short rod (314) which engages with a fork (262, 264) attached to the slide (200). The slide moves to and fro directly in a channel between a rest position and one supplying a current. The lever is fixed to the pivoted assembly (400) to enable rotation of the assembly about its principal axis (402). Steps (410) on the assembly prevent movement of the slide from an active to a rest position when the assembly is active. The rotation allows a spring-loaded stud (270) on the slider to pass through a channel (412) in the assembly to the exterior of the assembly. ADVANTAGE - Can select side according to traffic flow, and reduces battery charge consumption.

Description

 The present invention relates to the field of electrical switches for controlling lighting means and light indicators for motor vehicles.

 More specifically, the present invention relates to the control of light indicators generally called position lights or lanterns.

 Position lights are the lights used to indicate the presence and width of a vehicle.

 Such position lights are provided at the front and rear of the vehicle.

 Even more precisely, the present invention relates to means making it possible to unilaterally control the position lights, that is to say to selectively power either the right position lights or the left position lights.

 Such means are actuated when the vehicle is stopped with low visibility or after dark, to allow the presence of the latter to be indicated, while limiting the electrical consumption of the system taken from the battery, by limiting power to the position lights located on the side adjacent to the traffic corridor.

 Various means fulfilling the above-mentioned function have already been proposed.

 Control means have thus been proposed comprising secondary switches for selecting right or left in series with a main switch for controlling the position lights.

 Means for controlling direction change indicators have also been proposed, the conventional basic structure of which is adapted to present an overtravel making it possible to respectively control a selection of right or left position lights, as indicated above.

 The present invention now aims to improve the existing position light control systems allowing unilateral supply.

 According to the present invention, this object is achieved thanks to an electric switch for a motor vehicle comprising - main means for controlling position lights which can be moved between a rest position and an active supply position, - secondary means for selection control movable between a rest position and two respective selection positions, - biasing means which bias one of the first two control means towards the rest position, and - stop means provided on the second of the two control means , adapted to prevent free passage of said first control means from an active position to its rest position, when said second control means is itself placed in the active position.

 As will be understood on reading the detailed description which follows, thanks to the present invention, the movement of the second control means to their rest position, automatically brings the first control means to its position of rest.

 According to an advantageous characteristic of the present invention, the biasing means bias said main control means towards the rest position and the stop means are provided on the secondary control means.

 According to another advantageous characteristic of the present invention, the main control means comprise a drawer moved in translation.

 According to another advantageous characteristic of the present invention, the main control means further comprise a ring guided in rotation about an axis and comprising a structure eccentric with respect to this axis, in engagement with the slide, to control its movement at translation.

 According to another advantageous characteristic of the present invention, the secondary control means comprise a pivotally guided equipment.

 According to another advantageous characteristic of the present invention, the secondary control means comprise a lever linked to the pivoting equipment.

 According to another advantageous characteristic of the present invention, the ring is rotated on the lever.

 Other characteristics, aims and advantages of the present invention will appear on reading the detailed description which follows, and with reference to the appended drawings given by way of nonlimiting examples and in which - FIG. 1 represents a schematic view in perspective, partially exploded, of a device according to the present invention, in the rest position, - Figure 2 shows a sectional view, along the cutting plane referenced II-II in Figure 4, of the same device, in position rest of the main means and secondary control means, - Figure 3 shows a similar view, according to the same section plane referenced III-III in Figure 5, of the device according to the present invention, in the active position of the main means and secondary control means, - Figure 4 shows a cross-sectional view, along the section plane referenced IV-IV in Figure 2, of the same device, in position r epos.

- Figure 5 shows a cross-sectional view similar to Figure 4, along the sectional plane referenced
VV in FIG. 3, of the same control device, in the active position of the main means and of the secondary control means, and - FIG. 6 schematically illustrates the electrical contacts provided on an associated support plate.

 The device according to the present invention, shown in the appended figures, essentially comprises a plate 100, main control means comprising a drawer 200 and a ring 300, and secondary control means comprising a device 400 and a lever 500.

 The plate 100 is partially shown diagrammatically in FIG. 1.

 In practice, the plate 100 is formed - preferably a plate integrated into the switch housing. The plate 100 is advantageously formed by molding plastic material.

 The plate making up the plate 100 comprises on the one hand electrical contacts, on the other hand mechanical guide means.

 The electrical contacts carried by the plate 100 are preferably formed of electrically conductive tracks or bands associated with studs, sliders or the like, carried by the drawer 200 and the crew 400, or elements linked thereto, so that the link state of the electrically conductive tracks or strips carried by the plate 100 is modified when the slide 200 and / or the crew 400 is moved.

 An exemplary embodiment of such electrically conductive tracks or strips carried by the plate 100 will be described below, with reference to FIG. 6.

 The mechanical guide means carried by the plate 100 are intended to guide the slide 200 in translation in a direction of translation referenced 202 in FIG. 1 and to guide the crew 400 in rotation about an axis referenced 402 in the same figure. .

 To this end, the guide means provided on the plate 100 comprise, according to the embodiment shown in FIG. 1, a rectilinear channel 110, parallel to the direction of translation 202, of rectangular cross section, which opens onto a face * 102 of plate 100.

 In addition, the guide means provided on the plate 100 comprise two cylindrical caps 120, 122, located respectively on either side of the channel 110 and centered on the axis 402 of rotation of the crew 400.

 It will be noted that the axis of translation 202 of the drawer 200 extends parallel to the face 102 of the plate 100 on which the channel 110 opens. Furthermore, the axis 402 of rotation of the crew 400 extends perpendicularly to the direction of translation 202 and perpendicular to said face 102 of the plate 100.

 The drawer 200 can be the subject of numerous variant embodiments.

 According to the particular embodiment shown in the appended figures, the drawer 200 is formed of a block in the shape of a rectangular parallelepiped whose cross section is adapted to that of the channel 110, in order to slide in the direction 202 in said channel.

 - As indicated above, the drawer 200 carries studs, sliders or the like, elastically urged to bear against the electrically conductive tracks or bands linked to the plate 100, in order to modify the state of connection of these tracks or bands during its displacement.

 These tracks, cursors or the like can be the subject of numerous variants of realization, in particular in their geometry and their number.

 In FIG. 6, diagrams 210, 220, 230 and 240 show schematically such studs or sliders carried by the plate 100.

 The drawer 200 is provided on its upper surface 250 accessible at the level of the channel 110, with a fork 260. Said fork 260 comprises two branches 262, 264 generally parallel to each other and perpendicular to said surface 250.

 The ring 300 is designed to drive the slide 200 in translation in the direction 202. To this end, the ring 300 is guided in rotation, according to methods which will be specified below, about an axis 302.

 The axis 302 extends substantially perpendicularly to the direction of translation 202 of the slide 200 and to the axis of rotation 402 of the assembly 400. Thus, the axis 302- of rotation of the ring 300 extends substantially parallel on face 102 of plate 100 and on face 250 of drawer 200.

 The ring 300 is linked to a rod 310 centered on the axis 302. The rod 310 carries at its free end, by means of a pallet 312 orthogonal to the axis 302, a finger 314.

 The finger 314 is thus substantially parallel to the axis 302 and eccentric with respect to the latter. The finger 314 is engaged in the fork 260 between the two branches 262, 264.

 Those skilled in the art will readily understand that, by this fact, the rotation of the ring 300 around the axis 302 makes it possible to drive the slide 200 in translation in the direction 202.

 Obviously, it is possible to reverse the arrangements of fork 260 and eccentric finger 314, that is to say by replacing finger 314 linked to pallet 312 by a fork engaged on a single finger carried by the upper surface 250 of drawer 200 .

 It will be noted that the fork 260 is substantially centered on the axis 402 of rotation of the crew 400, in the rest position of the drawer 200 so that the drawer 200 can be easily controlled by rotation of the ring 300 whatever the position of the crew 400 around its axis 402.

 In addition, according to the embodiment shown in the appended figures, the drawer 200 carries a stud 270 guided in a bore formed in the drawer 200. This bore which receives the stud 270 extends parallel to the axis 402 of rotation of the crew 400 and opens onto the upper surface 250 of the drawer 200.

 The stud 270 is biased towards this upper surface 250 of the drawer 200 by means of an associated spring 272.

 More precisely still, although means are preferably provided on the slide 200 to limit the displacement of the stud 270 under the effect of the bias of the spring 272, as can be seen in the appended figures, at least in the rest position, the head 274 of the stud 270 emerges on the upper surface 250 of the drawer 200.

 This head 274 of the stud 270 is tapered in the direction of its free end, that is to say away from the surface 250 of the drawer 200. To this end, the head 274 of the stud 270 can for example be conical, frustoconical, pyramidal, spherical or equivalent.

 The function of the pad 270 will be explained later.

According to the embodiment shown in the
, attached figures, the equipment 400 has the general shape of a bell centered on the axis of rotation 402 and open in the direction of the plate 100, housing the plate 312, the finger 314 and the fork 260.

 The crew 400 thus formed is guided in rotation about the axis 402, by the plate 100, more precisely by the two above-mentioned cylindrical caps 120, 122. Where appropriate, additional means for guiding the crew 400 may be provided around the axis 402. These additional guiding means may for example comprise means for guiding complementary to a pin 404 integral with the crew 400 and centered on the axis 402. Such additional conventional guide means in themselves will not be described in more detail below.

 The crew 400 is rigidly linked to the lever 500.

Thus, it is understood that the actuation of the lever 500 rotating around the axis 402 allows to drive the crew 400 around the same axis.

 Again, the crew 400 carries pads, sliders or the like, elastically biased against the tracks or electrically conductive strips carried by the plate 100 in order to modify the state of connection of these during its rotation about the axis. 402.

 In FIG. 6, diagrams 410 and 420 have thus been shown schematically, studs or sliders carried by the crew 400 and resting against said electrically conductive tracks linked to the plate 100.

 More precisely still, the lever 500 is centered on the axis 302. The ring 300 is thus guided in rotation, in the intermediate position, on the lever 500 around the axis 302.

 Such structures of intermediate rings guided in rotation on a switch control lever are known in themselves to those skilled in the art. The assembly and guiding structure of the ring 300 on the lever 500 will therefore not be described in more detail below.

 In a manner known per se, the crew 400 is associated with means of indexing its rotational movement around the axis 402. More specifically, the means of indexing the crew 400 preferably define three stable positions around of the axis 402: a rest position as shown in Figures 1,2 and 4, and two active positions located on either side of the rest position, and symmetrical thereof. The crew 400 is thus represented in one of its active positions in FIGS. 3 and 5.

 Furthermore, preferably, the equipment 400 linked to the lever 500 and indexed in rotation about the axis 402 is advantageously adapted to control the direction change indicators.

 Thus, the crew 400 is equipped in a manner known per se with means for automatically returning to the rest position when the steering wheel is actuated. Such means of automatic flashing return control are well known to those skilled in the art and will therefore not be described in detail below. It will simply be recalled that generally these automatic return means are actuated by a cam integral with the steering wheel shaft.

 Such automatic return means are described and represented for example in document US-A-4748298.

 For its part, the ring 300 is also indexed in its rotation about the axis 302. Preferably, these indexing means define at least one stable rest position for the ring 300 and an unstable active position for controlling the lights. position.

 The indexed positions of the ring 300, in its rotation around the axis 302, can be identified by means of an index 304 placed on the ring 300 opposite symbols 504 provided on the lever 500.

 The ring 300 is shown in the indexed rest position in FIG. 1. In this position, the index 304 is placed opposite a symbol 504 "0".

 The unstable indexed position control position lights, for the ring 300, is obtained when the index 304 is placed opposite a symbol 504 11P ".

 Preferably, the ring 300 further comprises two stable indexed positions called "pilot" and "road", in its rotation about the axis 302, opposite the unstable position P, relative to the rest position o .

These two other stable positions of the ring 300 are advantageously used to respectively control a function for supplying the position lights and a function for supplying the main beam, code or headlight.

These two additional stable positions of the ring 300 are identified by symbols on the lever 500, opposite the index 304.

 As indicated above, biasing means bias the slide 200 in the rest position. These biasing means can be formed by a spring acting directly on the slide 200.

However, preferably, these biasing means are formed by the indexing means biasing the ring 300 from its unstable position P towards its stable rest position O. It is in fact understood that the biasing force applied to the ring 300 by these indexing means is transmitted via the finger 314 to the drawer 200.

 At its base, the crew 400 is provided with means cooperating with the head of the stud 270 of the drawer 200 to form a selective stop with respect to the latter.

 These means forming a selective stop bear the general reference numeral 410.

 More specifically, according to the particular embodiment shown in the appended figures, these means forming a selective stop 410 comprise a passage 412 placed opposite the stud 270, in the direction of translation 202, when the crew 400 is in the rest position.

 Seen from the axis 402, the section of the passage 412 is preferably complementary to the head 274 of the stud 270.

 Thus, the corridor 412 allows free translation of the drawer 200 in the direction 202 when the crew 400 is in the rest position.

 More precisely, as can be seen in FIG. 1, the lateral faces of the corridor 412 are inclined relative to a plane passing through the axis 402. These lateral faces are advantageously symmetrical with respect to this axial plane and diverge from that -this in approach to the drawer 200. This arrangement makes it possible to obtain a rotation of the crew 400 around the axis 402, by retraction of the pin 270 and compression of the spring 272, when the pin 270 is placed in the corridor 412 at time of the 400 crew rotation request.

 Furthermore, the means forming a selective stop 410 comprise, on either side of this corridor 412, walls 420, 425. The radially internal 421, 426 and radially external 422, 427 surfaces of these walls 420, 425 are inclined by relative to the axis 402. More specifically, the radially internal surfaces 421, 426 of the walls 420, 425 diverge with respect to the axis 402 in approaching the drawer 200. Conversely, the radially external surfaces 422, 427 of the walls 420, 425 converge towards the axis 402 in approach to the drawer 200.

Those skilled in the art will readily understand that the inclination of these surfaces 421, 426, 422, 427 of the walls located on either side of the corridor 412 facilitates the passage of the stud 270 under the equipment 400, by compression of the spring 272 when this passage is forced by an external force.

 ç The angular range of the inclined surfaces 421, 422, 426, 427 around the axis 402 must of course be adapted to the angular difference existing between the rest positions and the active positions of the crew 400 by rotation around the axis 402, so that these inclined surfaces 421, 422, 426 and 427 are always placed opposite the stud 270, in the active position of the crew 400.

 Furthermore, the translational travel of the drawer 200 between its rest position and its active position must be adapted so that, in the rest position of the drawer 200, the stud 270 is placed on the inside of the crew 400, while in the active position of the same drawer 200, the stud 270 is placed on the outside of the crew 400.

 There is shown diagrammatically in FIG. 6 an embodiment of electrically conductive tracks or strips carried by the plate 100 and capable of cooperating with studs or sliders 210, 220, 230, 240 carried by the drawer 200 and studs, equivalent sliders 410 , 420 worn by the crew 400.

 More specifically, there is shown in Figure 6, on either side of a dotted line 130, on the right the electrically conductive tracks carried by the plate 100 and cooperating with the pads 410, 420 linked to the crew 400 , and on the left the tracks carried by the plate 100 and cooperating with the studs or the like 210, 220, 230, 240 linked to the drawer 200.

 In other words, the tracks represented on the right of the line 130 in FIG. 6 cooperate with the direction change indicator control means, namely, the lever 500 in its pivoting around the axis 402 and l crew 400 associated. Furthermore, the tracks shown on the left of the line 130 in FIG. 6 cooperate with the lighting selection means, namely the ring 300 in its rotation around the axis 302 and the associated drawer 200.

 In addition, the circuit carried by the plate 100 and specific to unilateral marking in accordance with the present invention has been grouped together in the dashed line referenced 132 in FIG. 6.

 We thus see on the left of line 130, in FIG. 6, an electrically conductive track 140 permanently connected to the positive supply terminal of the battery, before the main switch actuated by the ignition key. We also see on the left of line 130, in Figure 6, a second electrically conductive track 142 carried by the plate 100 opposite track 140 above. The two tracks 140 and 142 are adapted to be connected by a pad or slider 230 linked to the drawer 200, when the ring 300 is placed in its active position identified by the index P on the lever 500.

 Thus, when the ring 300 is placed in the active position P, the track 142 of the plate 100 is connected to the positive supply terminal of the battery.

 We also see on the right of line 130, a track 144 carried by the plate 100 and permanently connected to the aforementioned track 142.

 In addition, we see on the right of line 130, in FIG. 6, two electrically conductive tracks 146, 148 placed opposite the aforementioned track 144.

The two tracks 146, 148 are adapted to be connected alternately to the track 144 by a stud 410 linked to the crew 400 when the lever 500 is moved in rotation around the axis 402, respectively in one of its two positions active.

 Track 146 is connected for example to position lights or left lanterns, while second track 148 is connected for example to position lights or right lanterns.

 I A person skilled in the art thus understands that the movement of the ring 300 and of the drawer 200 in the active position P makes it possible, by connecting the tracks 140 and 142, to prepare a supply of the position lights, while driving the lever 500 and the crew 400 in one of its two active positions around the axis of rotation 402 makes it possible to select the supply either of the left position lights or of the right position lights.

 Furthermore, there is shown on the left of line 130, in Figure 6, a track 150 permanently connected to the "plus after contact", that is to say to a positive supply line located after the switch controlled by the ignition key.

 The track 152 connected to the lighting means of the police plate can be connected to the track 150 by means of a stud 220 linked to the drawer 200 when the ring 300 is driven in its so-called pilot or road position mentioned above ( opposite the active position P relative to the rest position 0).

 Similarly, two tracks 154, 156 connected to the left and right position lights respectively can be connected to track 150 by means of studs 230, 240 linked to the drawer 200 when the ring 300 is driven in the same pilot or road positions .

 We also see in Figure 6, another track 158 carried by the plate 100 and permanently connected to the positive supply line "more after contact".

 Another track 160 carried by the plate 100 can be connected to track 158 by a stud 210 linked to the slide 200 when the ring 300 is driven in the road lighting selection position.

 Track 160 is itself permanently connected to a track 162. This track 162 can be connected to a track 164 for controlling the coded lighting means by an inverter 165. The same inverter 165 can in another position link together two tracks 166, 168 connected one to a headlight supply line, the other to the headlight lighting means.

 The reverser 165 can be controlled for example by the pivoting of the lever 500 and of the equipment 400 around an axis orthogonal to the axis 302 and to the axis 402.

 Finally, we see on the right of line 130 a track 170 carried by the plate 100 and permanently connected to a positive supply line. Two other tracks 172, 174 carried by the plate 100, facing said track 170, can be connected alternately to the latter by means of studs 420 carried by the crew 400, when the lever is moved respectively in the one of its two active positions around the axis 402. The two tracks 172, 174 are on their side, permanently connected to the direction change indicators.

 We will now describe the operation of the device according to the present invention.

 It will first be assumed that the crew 400 and the associated lever 500 are placed in the rest position, as shown in FIG. 1.

 The corridor 412 is therefore placed opposite the stud 270.

 The rotation of the ring 300 from its rest position O towards its unstable active position P consequently makes it possible to move the slide 200 in translation in the direction 202. During this movement, the stud 270 moves freely in the corridor 412.

 If the force exerted on the ring 300 is released, the active position P being unstable, the ring 300 returns to its rest position O. It is the same for the associated drawer 200.

 On the other hand if, when the ring 300 is placed in the active position P, and that consequently the stud 270 of the drawer 200 is placed on the outside of the crew 400, the latter is moved to the active position by rotation of the lever 500 around of the axis 402, one of the external surfaces 422, 427 comes to be placed opposite the stud 270 and forms a stop against the latter, preventing the return of the ring 300 and the drawer 200 to the rest position.

 We then obtain, as indicated previously with regard to FIG. 6, a supply of the position lights thanks to the connection obtained between the tracks 140, 142, and a selection of the right or left position lights thanks to the selective connection of the track 144 with one of the tracks 146 or 148. The position thus obtained is stable.

 The supply of the selected position lights can be stopped by manual actuation of the lever 500 in the rest position.

 In fact, track 144 is then separated from tracks 146, 148.

 Furthermore, as soon as the crew 400 is brought back to the rest position, the passage 412 is aligned with the stud 270. Under these conditions, the drawer 200 and the ring 300 are brought back to the rest position thanks to the associated biasing means. Tracks 140, 142 are then also separated.

 The interruption of the supply of the selected position lights can also be obtained by simple actuation of the ring 300 without initial intervention on the lever 500.

 In fact, thanks to the tapered geometry of the head 272 of the stud 270 and to the inclination of the radially external surfaces 422, 427 of the crew 400, the stud 270 can be forced to pass under the crew 400, by compression of the spring 272 following actuation of the ring 300.

 In this case, the return to the rest position of the crew 400 and of the lever 500 can be obtained subsequently either by manual actuation of the lever 500, or by means of the automatic return control means actuated by the steering wheel.

 We mentioned above, a return to the rest position and the crew 400 and the drawer 200 obtained by manual actuation of the lever 500. Of course, the same movement can be obtained by means of the automatic return control means in the rest position carried by the flywheel shaft. Indeed, the driving of the crew 400 by the cam linked to the steering wheel shaft leads to the same effect as the actuation of the lever 500.

 We mentioned above, a supply of position lights successively and in the order of actuation of the ring 300 in the active position followed by a movement of the lever 500 in the active position.

 The same result can be obtained in a reverse order, that is to say by successively ordering and in order, the lever 500 in the active position, to select either the right position lights or the position lights left, then moving the ring 300 to the active position.

 In fact, the crew 400 occupies a stable position when it is moved into the active position by actuation of the lever 500. One of the radially internal surfaces 421 or 426 is then placed opposite the stud 270. The latter can however be subsequently forced to pass under the crew 400, by compression of the spring 272 thanks to the tapered shape of the head 272 of the stud and to the inclination of said surfaces 421, 426, when the ring 300 is moved to the active position P. Following this actuation, the stud 270 being found on the outside of the crew 400, the drawer 200 is then maintained in a stable active position, although the corresponding indexing means of the ring provide an unstable indexing position.

 The supply of the position lights and the return to the rest position of the various components of the switch can be obtained in the same manner as indicated above (actuation of the lever 500, actuation of the ring 300 or intervention of the means automatic return linked to the flywheel shaft).

 Of course the present invention is not limited to the particular embodiment which has just been described but extends to any variant in accordance with its spirit.

 For example, it is conceivable to reverse the arrangement of the stud 270 and the means forming a stop 410.

In other words, an elastically stressed stud can be provided, similar to stud 270 on the equipment 400, while means forming a selective stop, similar to the means 410, would be provided on the drawer 200.
