Description

The present invention relates to an external mirror with a cup

  steerable controlled from the inside of a vehicle.

  Exterior mirrors ordered from

  The interior of the vehicle are generally of two types, one with a fixed cup and with an orientable mirror in said cup, and the other with an adjustable cup and a fixed mirror in the cup. On mirrors of the first type mentioned above,

  the deflection of the mirror in the cup requires the precision

  a relatively large clearance between said mirror and the cup which houses it. This game allows the introduction of foreign objects of all kinds and especially dust and

  water in the cup behind the mirror, which has the effect of

  in the long run, to clog and seize the mechanism

  tation of the mirror. Moreover, in winter, in snowy weather or

  freeze, the mirror is locked in relation to the cup.

  All these disadvantages are obviously avoided on external mirror mirrors fixed mounted in a steerable cup. However, the exterior mirrors of this type known at present have a serious drawback

  which limits their use, especially on vehicles that

  tible to drive at high speed. Indeed, the cup of a

  such mirror has a relatively large wind area

  aunt and if it is possible to compensate by symmetry the effects of the wind around the axis of orientation sky-earth of the rearview mirror, it is necessary to take into account the torque generated by the wind on said cup around the axis guidance

left-right of it.

  In addition, these mirrors are generally

  on the side of the vehicle by means of a side arm of a

  length, which further increases the importance of

  worn by the cup and must be overcome to guide

  in a left-right scan. Moreover, given the

  important wind pressure on the cup, which increases

  the speed of the vehicle, the fixing of the said

  shovel must be sufficiently firm to allow neither

  vibrations, nor the displacement of the field of vision.

  - a mechanism for engaging the coupling

between the handle and the cup.

  Preferably, the coupling means between the handle and the cup are essentially constituted by a toothed sector centered on the pivot of said cup and the latter and by a toothed pinion mounted on the hinge pin of the joystick and in permanent grip with the dry '

denteur.

  To engage the coupling between the cup and the handle, a locking lever is preferably provided.

  toothed pinion relative to said lever, this lever comprises

  an elastic return means in the disengaged position and preferably being housed inside the handle, which is

  hollow and articulated about an axis carried by it parallel

  its own axis of articulation on the support.

  To increase the multiplication at the level of

  the coupling between the handle and the cup, a train of

  auxiliary gearboxes may be interposed between the toothed sector and the idler gear, the gears of the said gear

  gear reducer rotating on axes carried by the support.

  The invention will now be described in more detail with reference to a particular embodiment cited at

  As a non-limitative example and shown in the drawings

nexes in which:

  Fig. 1 represents a vertical section of the retro-

viewfinder according to the invention.

  Fig. 2 represents a horizontal section of the retro

  viewfinder along the line II-II of FIG.

  As shown in FIGS. 1 and 2, the re

  mirror according to the invention is pivotally mounted on the coach-

  1 of a vehicle via a pivoting support

  consisting of a first outer square 2, a second square

  q.erre 3 interior and a hinge axis substantially ho-

  rice front through the body of the vehicle, said axis being essentially constituted by a bolt 4 on which is screwed a locking nut 5 for joining the two brackets 2 and 3 on either side of the shoulder of the body 1 taken in sandwich between said brackets. Using a bolt

  cup, lever located inside the vehicle

  within easy reach of the driver. Various solutions for

  this effort have already been devised and proposed

  that, for example, the use of a fairly long

  so much to steer the cup in all directions with great

  gear. However, such a lever constitutes within the

  a protruding device that does not comply with safety standards. Other devices have also been proposed such as single or double buttons, multiplying forces, or levers articulated in a complex way, or cable systems but all these solutions do not allow

  to have a relatively small effort just

  to move a mirror inside a fixed cup but

  not an orientable cup subjected to the action of the wind.

  The object of the present invention is therefore to

  placing an external mirror with an adjustable cup and a fixed mirror in said cup that can be controlled from inside the vehicle without effort using a joystick that does not pose any danger to the safety of the vehicle's passengers and allows the folding of the cup against the bodywork in case of

side impact.

  According to the invention, the external rearview mirror

  controlled swivel cup from the interior of a vehicle,

  door: - a pivoting support mounted on the vehicle body and articulated around a first substantially horizontal axis, - a hinge pivot of the cup carried by the support orthogonally to the first axis,

  - a folding handle for the orientation of the

  viewfinder located inside the vehicle and hinged about a second axis carried by the support parallel to the pivot of the cup, - disengageable coupling means between the cup and the lever to allow their folding and, and a nut allows to adjust at will the tightening of both

  brackets 2 and 3 on the bodywork 1 so as to have a

  pivoting port connected sufficiently close to the coach-

  to prevent accidental tipping of the rearview mirror and

  if that any excessive vibration of it. On the outside of the vehicle, the mirror

  comprises a cup 6 provided with a fixed mirror 7 and a bracket

  the lateral fastener 8 of flattened shape maintained pressed against the upper face of the outer bracket 2 of the support by a screw 9 serving as a pivot on which is screwed

  a nut 10 to adjust at will the clamping of the pat-

  8 of the cup on the bracket 2. The hinge lug 8 of the cup is extended on the opposite side thereof relative to its hinge axis 9 by a flared portion in the form of toothed sector 10 centered on said axis 9. This toothed sector 10 penetrates inside the vehicle through a slot 11 formed in the body 1, said slot being circular in shape centered on the axis 4 of rotation of the support

  to allow the rearview mirror to tilt around the

  said axis. The protection of the hinge of the cup against dust and bad weather as well as the tightness of the

  bodywork are secured by a bellows seal 12 envelopes

  pant said articulation and fixed on the one hand on the body

  of the vehicle and secondly at the birth of the cup 6.

  Inside the vehicle, the rearview mirror

  the invention comprises a folding lever 13 serving the purpose of

  cup in both the left-right direction and the sky-to-earth direction. This controller 13 is hollow and

  articulated on the inner bracket 3 by means of

  diary of an articulation axis 14 orthogonal to the rotational axis 4 of

  support and parallel to the axis of articulation 9 of the cup, said lever 13 thus moving in the same

  plane that the fixing lug 8 and the toothed sector 10 so

lidaire of the cup.

  Housed inside the lever 13 and mounted on the axis of rotation 14 of the latter is provided a pinion gear

  permanently meshing with toothed sector 10. In the

  the handle 13 is also housed a lever 16 allowing

  both to engage the coupling between the handle 13 and the coupling

  shovel 6, said lever 16 being hinged about an axis 17 parallel to the axis 14 of rotation of the handle and provided at its end close to the pinion 15 with a locking pin 18 which can

  mesh with the teeth of the pinion 15 to secure it in Roman

  with the controller. The lever 16 further comprises at its

  opposite end to the toothed pinion 15 with respect to its axis of

  articulation 17 a push button 19 coming out of the lever by a window 20 formed in the wall thereof, said button

  pusher protruding from the handle in position

  disengaged from it. Lever Recall 16 in said

  position is provided by a leaf spring 21 riseprécontrain-

  inside the controller, on the one hand, an ergot of

  on the inner face of the latter and, on the other hand, a

  heel 23 located on the back of the push button 19 (see Figure 2).

  The adjustment of the rearview mirror according to the invention is

  as follows: At rest, the lever 13 is folded around

  its axis of articulation 14 along the inner wall of the car-

  vehicle in a manner that would unduly impede the driver and not be a dangerous element for the safety of

  travelers. In this rest position, the lever 16 of the machine

  net 13 is pushed forward by its return spring 21 so that its locking pin 13 is not engaged

  with the teeth of the pinion 15 which can rotate freely

  turn of its axis 14 so that, in the event of a side impact, the

  cup 6 of the rearview mirror can be folded along the body-

  series of the vehicle without being obstructed in its movement by the said

pinion 15.

  When the driver wishes to adjust the

  left-right of the cup 6, it suffices to straighten the lever 13 substantially perpendicular to the plane of the

  body 1 and, by tightening the handle, pushing in the door

  your push-button 19, which has the effect of rotating the lever

  16 against the spring 21, which engages the locking finger

  18 of said lever in a hollow of the toothing of the pinion 15 which is thus locked in rotation relative to the lever 13. Any rotation of said handle around its hinge axis 14 will cause a corresponding rotation of the pinion 15 which will rotate the toothed sector 10 and the bracket 8 and the associated cup 6 around the hinge axis 9. The pinion 15 having a small radius compared to the length of the lever 13, in a ratio of the order from 1 to 10, the effort to exert on the controller 13

  to rotate the cup 6 will be ten times lower.

  When the driver has made the left-right adjustment of the mirror, it suffices to release its pressure on the push button 19, so that the lever 16 is biased forward by its spring 21, which has the effect of releasing the locking pin 18 of the toothing of the pinion 15, disengaging it from the lever 16 which can be folded again along the inner wall of the vehicle body. In the event of significant displacement of the cup 6, a single rotation of the handle may not

  to be sufficient, one then acts with it as with a po-

  ratchet and one can thus do several maneuvers if necessary.

  For a sky-to-earth adjustment, it is sufficient to

  wrap the handle 13 folded along the inner wall of the

  body and raise or lower it. through

  median of its hinge axis 14, said handle 13

  exerts a torque on the inner square 3 of the

  port which pivots about the horizontal axis 4 and at the same time drives the tilting of the cup 6 about said axis by means of the outer bracket 2 and the hinge pin 9 of said cup. In order to reduce to the maximum and even to cancel the resisting torque due to the thrust of the wind and tending to tilt the cup around its horizontal axis of rotation 4, it suffices to lower it so that its horizontal axis of symmetry substantially coincides. with the axis of the bolt 4 of the support formed by the two brackets 2 and 3. In addition, the lever arm offered by the lever 13

  being significantly more important than the possible lag

  the horizontal axis of rotation 4 of the cup and its axis of horizontal symmetry, the effort to exert on said handle

  to make a sky-to-earth adjustment of the rearview mirror is born-

  negligible. In order to further increase the gear ratio in a left-right adjustment of the mirror cup according to the invention, a reduction gear train may be interposed between the pinion 15 and the toothed sector 10, the gears constituting said train being constantly in position. taken with the pinion 15 and the toothed sector 10 and mounted loosely on the axes carried by the bracket 3 of the support parallel to the articulation axes 9 and 14 respectively of the cup

6 and the lever 13.

  Of course, the scope of the invention is not limited to the single embodiment described above by way of non-limiting example, but it also covers

  all variants incorporating equivalents.
