Description

Plug plug holes in plates.

Object of the invention

The present invention relates to a plug hole shutter in sheets, of the type used for the  sealing and sealing of holes made in sheets, by example in the sheet belonging to the body of a vehicle.

Background of the invention

Various caps are currently known or elements for sealing holes made of sheet metal vehicle body or other components.

For example, in the Spanish invention patent  ES2006404 describes a plastic closing lid, to close specifically an opening of a vehicle body automobiles, which includes a perimeter sealing lip in inclined arrangement and an opposite elastic interlocking ring to said lip; leaning the mentioned lip and ring on the faces of that area of the sheet that delimits the hole a shut

This closing cover comprises below the interlocking ring a support capable of being configured by another elastic lip, which presses against the ring of interlocking to keep them in permanent contact on the surface corresponding to the element or sheet on which it is made the hole that seals the lid, in order to get a air tightness.

In the Spanish invention patent ES2097565 describes another elastic closure cap that has some features aimed at increasing tightness, including for this a heat deformable joint and pins cover anchor.

In the invention patent ES 2125148 it is given know a shutter to seal holes in sheets, designed, in in particular, for sealing holes made of sheets, such as of car bodies. This shutter is of the type of comprising a bowl-shaped body with an outer wing peripheral and a peripheral inner wing, divergent, starting of the opposite ends of the shutter neck and acting on the opposite faces of the sheet that delimits the hole; internally disposing the outer peripheral wing of a ring of flux material in order to provide the corresponding sealing area on the surface of the sheet on which apply

In the Spanish utility model ES1022542U a shutter is described for an opening made of a sheet, which also incorporates a flexible glue or gasket, which melts with heat, and also deformable wings or legs for anchoring in the lid assembly on the corresponding opening
ra.

In European patents EP631923 and EP779203 are describe two sealants-sealants equipped with two sealing zones or bands based on a flux material or glue, to define two sealing and sealing zones.

In the invention patent ES 2 240 676, describes a sealant-sealant comprising two tail rings, or hot melt material, arranged internally  under the outer curved perimeter wing of the part of the shutter-sealer and neck set in the shutter-sealer part, with the particularity that both rings can be joined by nerves equidistant from each other, or forming a unique body and full

Shutters or background plugs cited present some characteristics oriented to look for a high seal tightness established by the cap on the hole to be sealed, however they have the disadvantage that can only be used to seal holes of a certain nominal diameter. These limitations determine that it is necessary manufacture for certain industries, for example the automobile, different plugs to seal diameter holes very similar, for example 38 and 40 mm., which, in addition to increase manufacturing costs, additionally raises a increase problem of stock for the factory or company that Mount the plugs.

Description of the invention

The plug plug holes in object plates  of this invention is of the type used for sealing and sealing holes made of sheets, for example in the sheet belonging to the body of a vehicle, and presents some constructive particularities oriented to allow the shutter, effectively, of holes of different diameters and between maximum and minimum values.

This plug is the type of constituted by a bowl-like body, whose outer wall it presents perimeter, on its outer face, an upper wing and a lower wing facing and diverging in opposite directions, delimiting said wings an intermediate gap for the reception of that annular potion of the sheet surrounding the hole a shut

In accordance with the invention and in order to get a correct centering of the plug in the hole to be sealed, the outer wall of the body of the cap has on its outer face a series of centering nerves that extend in one direction substantially vertical from the lower end to the end upper of said outer wall. The prolongation of these nerves centers to the lower end of the outer wall of the body allows the centering nerves to exert their function from the moment in which the confrontation of the end is carried out bottom of the cap with the hole to be sealed.

These centering nerves are found arranged in correspondence with radial cuts defined in the lower wing, and faced with the longitudinal median plane of said radial cuts.

The aforementioned radial cuts allow the lower wing does not interfere with nerve performance centering with respect to the hole of the sheet, and determine that the lower wing consists of a series of sectors independent, laterally delimited by said cuts and that they form stoppers of stopper of the cap, in the position of assembly, with respect to the sheet.

These sectors extend from the end lower or from an area very close to the lower end of the outer wall of the cap body to an area near the inner surface of the upper wing, therefore presenting a sufficient length to allow mounting and retention of the cap over holes of different diameters.

On the other hand, the conformation of the lower wing through the aforementioned sectors allows those sectors can be flexed independently, which notably simplifies the introduction of the lower end of the plug through the hole to be sealed and consequently the assembly of the plug in said hole.

According to the invention, the nerves centers have a width smaller than the radial cuts of the lower wing, and the sectors have a length slightly less than the total height of the outer wall of the body of the cap thus ensuring that once introduced a certain length of the plug through the hole the sectors of the lower wing, bent towards the upper area by contact by the contour of the hole, release from the sheet and act due to its divergent configuration against the bottom surface of the sheet, guaranteeing the retention of the plug in the position of mounting.

With the configuration described above, this cap has on the lower face of the upper wing and, in a area near its free end, perimeter reliefs on which is applied a tail ring or flux material responsible for ensuring the seal of the closure established by the plug over the hole of the sheet, although it is not limiting this closing system to the use of the tail ring or flux material, since the cap may or may not include it.

Preferred embodiment

In the exemplary embodiment shown in the attached figures the plug has a body (1) as a way of bowl whose outer wall (3) presents perimeter, in its outer face, an upper wing (2) and a lower wing (4) facing each other and that diverge in opposite directions, presenting the lower wing (4) a series of radial cuts (41) that delimit laterally a series of sectors (42) that can be flexed so  Independent.

The outer wall (3) of the body (1) presents in  its outer face a series of centering nerves (6) arranged in correspondence with the radial cuts (41) of the lower wing (4) and faced with the longitudinal median plane of said cuts radial (41).

The sectors (41) of the lower wing (4) extend from the lower end or from a very area next to the lower end of the outer wall (3) to an area next to the inner surface of the upper wing (2), which allows said sectors (42) to be of sufficient length to allow the use of the plug in the sealing of holes of different diameters and included within maximum and minimum values.

The length of these sectors (4) is slightly lower than the total height of the outer wall (3) of the  body (1) to allow the cap to be mounted on a hole (71) to be sealed and defined in a sheet (7).

To ensure the seal tightness established by the plug over the hole (71) to be sealed, the wing upper (2) presents on its lower face and in an area close to its free end a ring of glue or flux material (5).

In the example shown in the figures, the wing upper (2) presents, in the area of application of said ring (5) of glue or flux material, perimeter reliefs (21) that collaborate in the retention of the ring (5) on the upper wing (2).

With the characteristics described above the plug allows its mounting on holes (71) of different diameters, as can be seen in figures 5 and 6, since the extension of the centering nerves (6) to the lower end of the outer wall (1) allows said nerves exert their centering function without interfering, thanks to the cuts (61), in the flexion of the sectors (42) of the lower wing during the introduction of the plug in the hole; remaining guaranteed the retention of the cap by the length of the sectors (42), which press the sheet (7) against the tail ring (5) or flux material applied to the inner face of the upper wing (2).

Once nature is sufficiently described of the invention, as well as a preferred embodiment, for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not imply an alteration of the essential features of the invention claimed in continuation.
