DESCRIPTION

Fluid retention device for vehicle door

OBJECT OF THE INVENTION 5

The object of the present patent application is a fluid retention device for the vehicle door according to claim 1, which incorporates notable innovations and advantages.

 10

BACKGROUND OF THE INVENTION

The main components of the doors of current motor vehicles are: frame, window frame and coverings. Structurally the piece that stiffens the door assembly is the frame.

The door assembly has an inner lining, or finishing of the door on the side of the passenger compartment, and an outer lining or skin, which covers the door on the outer face of the vehicle. Thus, between the inner lining and the outer lining or skin, there is a hollow space. Part of said hollow zone is called the wet zone, since it is not completely isolated, since the upper part of said cavity between both parts is partially open: it is the hollow through which the glass enters when it is collected, in the operation of opening the window by the user. This upper opening favors the entry of particles such as dirt, dust, pollution, pollen ... or water. These elements are deposited on the inner faces of the frame and the outer lining.

Point out that the bottom of the door is closed, and therefore there is no way that water and other incoming particles come out. In order to prevent the water from being stagnant inside the cavity, there are small longitudinal holes located in the lower part of the frame.

On the other hand, and with the aim of preventing the corrosion of the sheet, the inner faces of the frame and outer lining are impregnated with a 35 rust protection bath (KTL (kathodische Tauchlackierung - cathodic immersion paint) and / or waxes). The application of this primer protects the surface of the sheet from being oxidized as a result of being in contact with moisture, the result of unwanted entry of water into the hole.

 5

These holes allow the necessary evacuation of water in order to prevent the accumulation of moisture inside. However, these holes have a great disadvantage: The surplus of primer applied to the interior walls of the pieces that make up the interior hollow of the door is not adhered 100% to the surface, which causes this surplus of primer to slide little by little, accumulating in the lower part of the interior of the door cavity, ending up going out through the drain holes. Said primer, in addition, is mixed with particles of dirt, dust, contamination, which have previously entered through the hole in the window. Thus, the fluid that flows out of the drain hole is a dark color which causes a zone seen by the user, such as the heel of the vehicle, to be stained. fifteen

It is also known from the state of the art, as reflected in JP2001233054, an orifice plug composed of a rubber element, which expands and deforms by the impregnation of water, and by a resin base material that does not deform For the water. When water accumulates in an inner panel of the door, a part of the orifice plug formed of rubber expands and is deformed by water. Expansion and deformation causes a hole in the hole plug so that water can flow out.

Thus, it is seen that there is still a need to have an alternative device that is applied to the doors to avoid visible stains without penalizing the correct drain.

DESCRIPTION OF THE INVENTION

In accordance with the present invention, this task is solved by means of a fluid retention device for vehicle door according to claim 1. Additional advantages of the invention are presented accompanying the features included in the 5 dependent claims mentioned in the description to be review below.

The objective of the present invention is to prevent the heel of the vehicles from being stained due to the spillage of excess rust protection mixed with 10 particles of dirt and dust through the drain hole of the doors of a vehicle, without preventing This spill has an impact on the correct drainage of water that may be accumulated in the interior cavity of the door.

The function of the device of the present invention is to create a brake for the exit 15 towards the outside of the body of the primer or wax that is applied inside the doors in order to avoid corrosion. Said device or part is located in the drain holes of the doors, and retains the primer or wax that comes off, while allowing the evacuation of water through the drain holes, preventing the heel of the cars from being stained by said detachment. twenty

Thus, and more specifically, the fluid retaining device for vehicle door comprises means for fixing to an outline of at least one hole in a wall of said door, and a fluid retaining wall where said retaining wall partially closes said hole , and forms a cavity between the retaining wall and the wall of said door. In this way, the retaining part does not buffer the entire hole, but rather performs a retention function as a "bowl", creating a slight concavity in the lower part of said hole. Thus, and by retaining and accumulating fluids, mixed with particles and dirt, the unsightly stain on the heel of the vehicle is avoided in the event of a spillage from the drain hole of the door. 30

It is worth mentioning that the amount of wax released due to the surplus printed on the inner surface of the frame is not continuous in time, since its greater detachment occurs shortly after leaving the vehicle after its manufacture. With the passage of time this amount released decreases. 35

According to a preferred embodiment of the invention, the retaining wall and the door wall form a sealed cavity. In this way there is no outflow of fluid outwardly other than through the orifice of the door wall, preventing there from being a loss of fluid that goes out to the outside anyway through the retaining wall junction and of the wall of the door, producing likewise a staining of the body of the vehicle.

According to another aspect of the invention, the retaining wall has a predefined height to accumulate fluids of density greater than a threshold value in the cavity between said retaining wall 10 and the wall of said door. In this way it is achieved that the fluids of higher density (KTL primer, solid particles, etc ...) remain at the bottom of this cavity.

According to another aspect of the invention, the retaining wall has a predefined height to allow fluids of density of less than a threshold value to pass through the hole in the door. In this way, fluids of lower density (water, or low density solutions) are allowed to be evacuated through said orifice.

In a preferred embodiment of the invention, the fixing means comprise at least two fixing clips to the contour of said hole. Thus it is achieved that the retention device is fixed to the door of the vehicle, by two separate elements, giving the fixing a greater solidity.

More specifically, the fixing means comprise at least one centering clip in the contour of said hole. Said centering clip allows, on the one hand, a preassembly, that is to say a provisional clamp, prior to its definitive positioning, and, on the other, to absorb manufacturing deviations once assembled, preventing its movement both vertically and horizontally.

 30

Advantageously, the contour of the hole in the wall of said door is substantially elongated, and at least one of the ends of the contour of said hole is substantially rounded, wherein the at least one fixing clip rests on said end of the hole above a midpoint of substantially rounded end. The midpoint of the substantially rounded end means the point of said rounded section that would result from dividing said rounded section into two parts of equal length. Said at least one fixing clip is intended to fix the piece in its position of use. Thus, in a particular embodiment there are two fixing clips, they are not exactly located at the midpoint of the curve that forms the sides of the collision hole, but are slightly offset upwards. This prevents the piece from tending to present 5 vertical movements. By collision hole is meant an elongated hole whose ends are preferably semicircular. Vertical direction means the direction perpendicular to the direction in which the hole is elongated, which coincides with that of the vehicle floor, substantially horizontal.

 10

More particularly, since the contour of the hole in the wall of said door is substantially elongated, and that at least one of the ends of the contour of said hole is substantially rounded, the device comprises at least one centering clip that rests on said end. of the hole below the midpoint of the substantially rounded end. Thus, and additionally at least one fixing clip, and in order to ensure the total fixation of the retaining part, at least one centering clip is placed, preferably smaller than the fixing clip, which serves to prevent its unwanted movement in if there are possible vertical or horizontal manufacturing deviations, in the case of facing the most unfavorable situation in the tolerances of the retaining part and the collision hole. In this way, the at least one centering clip enables the device to remain stable in a pre-assembled situation (of no definitive fit).

In a preferred embodiment of the invention, the height of the retaining wall is substantially equal to the prolongation of the midpoint of the curve of the at least one of the 25 substantially rounded ends. In this way, a compromise situation is achieved between the fluid retention function containing dirt particles and waxes, and the low density fluid drain function.

In another preferred embodiment of the invention, the at least one centering clip rests on the edge surface of said contour. In this way the retention device is held in the hole itself, without the need for any additional part or element.

Advantageously, the retention device is made of a plastic material, which offers a good compromise between rigidity and flexibility, as well as price and ease of production. 35

More specifically, the plastic material is PP-polypropylene or PA-polyamide, given the good performance of this type of plastics in the environmental conditions to which a vehicle is exposed in its useful life.

Additionally, the invention comprises a vehicle door which in turn comprises a fluid retention device according to claim 1. Said door has the above mentioned advantages of having said device.

The attached drawings show, by way of non-limiting example, a fluid retention device for vehicle doors, constituted according to the invention. Other features and advantages of said vehicle door fluid retention device, object of the present invention, will be apparent from the description of a preferred but not exclusive embodiment, which is illustrated by way of non-limiting example in the drawings which are accompanied, in which: 15
