Description

Support plate for car drivers.

Object of the invention

The present invention relates to a sheet support, of the type used in the automobile industry, for fixing their pilots, especially each pilot rear.

The object of the invention is to achieve a perfect adaptability of the pilot to the vehicle body, with a structurally simple and consequently economic support, that offer optimum performance from the point of view operational, ensuring a perfect piping of the external surface of the pilot with the external surface of the body on which It is integrated.

Background of the invention

As is known for car drivers, in special later pilots, both for aerodynamic reasons as for design reasons, they tend to be flush with the sheet constitutive of the body of the vehicle, specifically occupying a window operatively practiced in said outer sheet.

More specifically each of these windows it closes by means of an inner sheet, joined by welding to the rest of the body, inner plate properly configured for define a housing in which the corresponding pilot fits, which supports perimetrically over stops operationally established for that purpose, which theoretically should generate a perfect surface continuity between the outer surface of the pilot and the external body surface.

However, in practice the results diverge to a greater or lesser extent from the aforementioned theory, due to the own tolerances, that is to say the measurement variations of the different pieces, to which there are also add variations due to the deformations that occur in the joints between plates, by welding effect.

So that the pilot has an optimal setting is it is necessary to support and focus on the outer plate of the vehicle, which is the one that is not subjected to any of the problems cited, since dimensional differences accumulate in the fixing area, between the pilot to be fixed and the support plate to which it is fixed.

This solution creates tensions that can cause the breakage of the pilot to be fixed.

One way to solve this problem is to provide the piece to be fixed of a screw with a compensating spring of the dimensional differences. However, this solution causes a significant cost increase in the pilot, also increasing the complexity of it.

Description of the invention

The support plate proposed by the invention solves the problem fully satisfactorily previously exposed, constituting a structurally solution very simple, consequently economical and with full reliability operational

For this and more specifically said sheet focuses its characteristics on the fact that, surrounding the classic fixing hole to the pilot, incorporates a plurality of annular and concentric undulations with said hole of fixing, so that this special configuration of the sheet allows an elongation of it, that is to say a deformation elastic with the possibility of axial displacement of the central zone of the same in which the repeatedly cited hole of fixation.

In this way the same effect is achieved. elastic than with the spring mentioned above, but in absence of said spring and in the stamping operation itself to obtain said sheet, without using elements of stamping with proper configuration on their surfaces operational

Logically and to the effect of maximizing the axial and elastic displacement capacity of the sheet support, said annular corrugations, preferably circular, will be of the maximum diameter that allows the size and configuration of said sheet.

Otherwise the pilot will be fixed, as is conventional, using the classic back neck, internally threaded and coaxially facing the fixing hole of the sheet, and the complementary screw topped on the handle or knob acting on it, so that in the tightening of said screw will produce elastic deformation of the back plate or support plate, which will be displaced outward, tending permanently recover their initial position and rest, which it involves permanent traction on the pilot, which is maintained like this perfectly adapted to the exterior plate of the vehicle, with a Perfect surface continuity with the latter.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows, according to a view in plant, a support plate for car drivers made of according to the object of the present invention.

Figure 2.- Shows a detail in section transverse of the sheet of the previous figure, duly integrated into the body of a vehicle and to which it appears attached The pilot to support.

Preferred Embodiment of the Invention

In the figures outlined, specifically in the Figure 2, the support plate (1) on which the invention, sheet that by welding (2) is immovably fixed to the outer plate (3) constituting the surface seen of the vehicle body, defining with the latter a housing (4) for location of the piece to be fixed, that is to say rear pilot (5), whose outer surface (6) should be perfectly flush with the aforementioned outer sheet (3) of the body, as seen in the upper left of the cited figure 2.

Well, according to the invention, the said support plate (1) focuses its characteristics on the incorporation of a plurality of annular undulations (7) concentric with the hole (8) of the sheet (1) for fixing the pilot (5), preferably circumferential and of the greatest diameter allowing said support plate (1), as in turn observed in the Figure 1, so that in said support plate (1) a wide flexible zone (9), elastically deformable.

The pilot (5) will support directly on the outer sheet (3) of the body, through stops positioners (10-10 '), in a position where the outer surface (6) of said pilot (5) makes up with the external surface (3) of the body plate, such as shows figure 2 and in which the classic neck (11) internally threaded is coaxially facing the hole (8), to receive the classic fixing screw (12), keyed to the inner plate or support plate (1) and outside It is finished off in the classic manipulation knob (13), which it is the one that is really fixed or keyed to the support plate (1) and acting on the screw (12) with interposition of a small board (14).

In this way the support plate (1) passes from the resting situation A shown in figure 2, to the position of work B also shown in said figure, position in which the elastic deformation of the support plate (1) generates traction permanent on the neck (11) of the pilot (5) and consequently a perfect adaptation of it against the stops (10-10 ').
