Description

Shield for door handles.

Object of the invention

The present invention, as expressed in the statement of this specification refers to a shield for door handles whose purpose is to facilitate the assembly and disassembly of the door handle shields, lowering manufacturing costs and providing a set of great solidity and excellent aesthetic appearance; also facilitating the realization of the shield with respect to nearby models in the State of The technique.

Background of the invention

Shields for door handles are known  consisting of a circular piece or base shield that includes a central hole for the passage of the handle or handle and about minor holes around it for the passage of the screws that determine their attachment to the corresponding door. So that heads of said screws are hidden, these base shields they have an external thread in their lateral surface by means of a coupling shield is attached whose interior has a complementary threading. These known shields feature the drawback that the threads of the base shield and the beautify these pieces remarkably expensive, and also their disassembly is usually quite expensive since the bezel It has a smooth knurled surface that makes it difficult to unscrew, which is usually already difficult because there is little grip surface and for having been a long time since it made the assembly. These inconveniences have been conveniently solved by the Utility Model No. 9501985, which provides a shield for door handles consisting of a base shield with a central hole for the passage of a handle and with other holes surrounding the center to locate the screws fixing to the corresponding door, this being attachable shield to a bezel that hides the heads of said screws and presenting the lateral surface or perimeter edge of said base shield a housing for O-ring, so that the coupling between the trim and the shield is made by pressure by means of the elastic jump of the referred O-ring, thus avoiding the need for threading between the bezel and the base shield However, said Utility Model No. 9501985 It has the disadvantage that to incorporate the O-ring in the shield uses a perimeter channel in said shield, which determines the need for elements articulated in the mold that allows the realization of that shield, increasing manufacturing costs; so that it would be desirable to have a shield in which the incorporation of the mentioned O-ring does not require the aforementioned perimetric channel in the shield, that is, that the O-ring could be fixed on the shield with means other than the referred channel perimetric.

Description of the invention

To achieve the objectives and avoid drawbacks indicated in previous sections, the invention consists of a shield for door handles applicable to handles for doors that are constituted by a base shield with a central hole for the passage of a handle, with other holes that surround the central and that allow to locate the screws of fixing to the corresponding door, and attachable to a trim that hides the heads of these screws; where the surface side or perimeter edge of said base shield incorporates a housing for an O-ring, so that the coupling between the bezel and the shield is made by pressure, by the elastic jump of the referred O-ring.

Novelly, according to the invention, said O-ring housing is constituted by two rows parallel of outdated projections that surround the perimeter shield, the board being arranged between said two rows of Highlights

This shield configuration allows, in addition to avoid threading between said shield and the corresponding trim, housing the aforementioned O-ring on the edge of the shield without the need to make a perimeter channel in the lateral surface or outer edge of the shield. With this they get cheaper the manufacturing costs of the base shield, since the referred shield may be made in molds lacking joints and that allow the extraction of the piece in any direction. Also I know they maintain all the advantages presented by the Utility Model No. 9501985 referred to in the Background section of the Invention.

Then, to facilitate a better understanding of this descriptive report and being an integral part of the same, some figures are accompanied in which with character illustrative and not limiting the object of the invention.

Brief description of the figures

Figure 1.- Represents a perspective view and exploded of a door handle in which the shield of the present invention.

Figure 2.- Represents a perspective view. of the door handle shield of the previous figure 1, a Once it has been attached to the corresponding trim by an O-ring.

Figure 3.- Represents the views in raised plan and shield profile for door handles of the previous figures.

Description of an embodiment of the invention

Following is a description of a example of the invention, referring to numbering Adopted in the figures.

Thus, the door handle shield of this example of implementation is applicable to handles of which they constitute by means of a base shield 1 with a central hole for the passage of a handle 5, and with other holes surrounding the center for the location of the fixing screws to the corresponding door.

In addition, the shield 1 is attachable to a Trim 3 to hide the heads of the referrals screws

The lateral surface or perimeter edge of the base shield 1 has a housing for an O-ring 2, so that the coupling between the bezel 3 and the shield 1 it is carried out by pressure through the elastic jump of the joint toric 2.

This O-ring housing 2 in the shield 1 is constituted in the present example by perimeter projections 4 of said shield 1, which are they are arranged in two rows and out of phase, just as It can be seen in Figures 1 and 3.

Thus, to assemble the components 1, 2 and 3 of the handle, the joint 2 must simply be placed between the projections 4, so that the outer edge of said joint 2, will protrude slightly from the
perimeter of the shield 1, after which it can be coupled by elastic jump and with a slight pressure on the bezel 3, said components being arranged as shown in Figure 2.

This simple and ingenious configuration of the board housing 2 on shield 1 greatly facilitates the realization and demolding of the shield with respect to the shields of the State of the art.
