DESCRIPTION OF A PREFERRED EMBODIMENT

[0044] Below is a description of a number of embodiments of the fixation assembly of the wing mirror mounting structure for vehicles, as well as of the wing mirror including the fixation assembly of this invention, with reference to the figures indicated above.

[0045] According to a preferred embodiment, and as can be seen in FIG. 1, the fixation assembly (10) basically incorporates three main elements, a rotation shaft (11), or shank, which acts as the element on which the moving part of the wing mirror (100) will pivot.

[0046] On the other hand, a fixed part (12) is inserted in the rotation shaft (11) in a coaxial way, to be coupled jointly to the base (13) of this rotation shaft (11) and to create an actuator sub-assembly (11, 12).

[0047] Finally, as another basic element in the fixation assembly (10) there is a bracket (16) that is located next to the base of the wing mirror (100) that is fixed to the vehicle in its body and/or door.

[0048] As can be seen in FIGS. 2 to 4, the bracket (16) has a receiving face (17) for the actuator sub-assembly (11, 12) with an opening (18) that has a geometry perceptibly identical to the base (13) for the introduction through said opening (18) and that once inside it, a rotation of said actuator sub-assembly (11, 12) can be made, by a space (19) in the form of a groove or similar, between the receiving face (17) as a retaining element for the output of the actuating sub-assembly (11, 12), and the seat (20) of the bracket (16) as a stop element for the insertion displacement of the actuating sub-assembly (11, 12) in said bracket (16).

[0049] The fixed part (12) is coupled to the base (13) of the rotation shaft (11), the perimeter shapes of the fixed part (12) fitting into the housings/protuberances (30) of the base (13). With this coupling, the actuating sub-assembly (11, 12) moves jointly in the radial movement. The fixation on the base (13) of the fixed part (12) also means that certain parts of the fixed part (12) are below the receiving face (17) of the bracket (16), which also makes a retention of the fixed part (12) together with the rotation axis (11) in its longitudinal movement with respect to the direction of insertion in the bracket (16) coaxial with the rotation shaft (11).

[0050] As part of the base (13) of the rotation shaft (11), there is a ramp-shaped protuberance (21), as a means of fixation of the position, which once in the space/groove (19) inside the bracket (16) when the actuating sub-assembly (11, 12) rotates, comes into contact with the means of anchorage of this bracket (16), formed by an additional ramp (22), as can be seen in FIGS. 5 to 7. In the step of saving this ramp (22) of the bracket (16) a slight longitudinal displacement of the base (13) of the rotation shaft (11) with respect to the bracket (13) is carried out to overcome this ramp (22), returning to its longitudinal position in a recess (23) of fixing the position perceptibly equal to the initial one, although slightly separated as this housing is not at the same level carrying out a certain compression, as can be seen in FIGS. 8 to 10.

[0051] Once the ramp (22) has been bridged, the bracket has the recess (23) with walls perpendicular to the spinning plane of the rotation shaft (11) for its retention. In order to prevent the ramp (21) of the rotation shaft (11) from overcoming the perpendicular wall that follows in the direction of rotation of the fixation, there is a protuberance (24) at the base (13) of the rotation shaft (11) as a locking element of the fixation to stop at the end of the section of the opening (25) of the seat (20), coinciding with the area of fixation of the position of the recess (23) in the bracket. In the present embodiment, this blocking protuberance (24) is part of the same part of the base (13)

[0052] The fixation assembly (10), in the assembly of the rotating mechanism (50) of the mirror to be installed in it, shall incorporate a spring (26) as an elastic element which exerts pressure against any movement of displacement of the rotation shaft (11) which is a longitudinal displacement of the insertion position in the fixing space/groove (19).

[0053] As an alternative embodiment to the above, the protuberances and recesses can be exchanged in an equivalent manner between the interacting parts, so that the effect achieved is not altered. In the same way, and also in an alternative way, the ramps can be substituted by curved elements, as for example ratchets, that also obtain the same effect sought, without altering the essence of the characteristics characterising the invention

[0054] The wing mirror (100), as can be seen in FIG. 11, which contains the previous fixation assembly (10), has the advantages provided by the previous embodiments, allowing the fixing structure to be assembled in the base of the wing mirror (100) which is attached to the body/door of the vehicle.

[0055] Despite the fact that reference has been made to a specific embodiment of the invention, it is clear to a person skilled in the art that the fixing assembly of the wing mirror mounting structure for vehicles, as well as the wing mirror including the described fixation assembly, is susceptible to numerous variations and modifications, and that all the details mentioned can be replaced by other technically equivalent ones, without departing from the scope of protection defined by the attached claims.
