Description

Eyelet device.

Object of the invention

The present invention relates to a eyelet device that provides essential characteristics of novelty and notable advantages over known media and used for the same purposes in the current state of the technique.

More particularly, the invention proposes the realization of an eyelet device, preferably injected into plastic material, obtained from two separate pieces, complementary, of which a first piece constitutes the piece of base and includes a specially adapted cylindrical central neck to be riveted while fixing the eyelet in position operational, and of which a second piece consists of a washer which, coupled to the neck of the base piece, constitutes the element of fixation to the material on which the device is applied eyelet, with no possibility of unwanted losses or displacements, and with an increased retention capacity thanks to the provision of internal protrusions formed around a central opening of the washer, and projected against the base piece.

The field of application of the invention obviously belongs to the handling and treatment of materials laminates such as fabrics or the like, with a view to provision of eyelets or other types of passage openings.

Background and Summary of the Invention

Those skilled in the art are knowledgeable about the need that often occurs in certain sectors of the current state of the art regarding the provision of holes or openings in fabrics, plastics or others materials for the passage through other elements, normally filiform, of the type of the cords, the tapes, etc. This is one permanent need in the current state of the art and, in fact, have already developed some types of devices that once coupled to the supports in question, constitute openings of eyelet type for the commented functions.

In particular, there are some types of eyelets obtained from separate elements that can be applied to Any laminated support material for the expressed functionality These eyelets must inevitably meet the requirement of immobility once applied to the support, together with the guarantee of a secure fixation between the parts or pieces that make up. Usually eyelet devices currently used for the provision of eyelets or passage openings, are normally consisting of two mutually attachable pieces between yes, of which one of them, considered as the base of the eyelet, is constructed so that it can be applied over the other as a rivet, thereby providing the fastening of the eyelet to the support, previously inserted between both eyelet pieces.

Given the above, this invention has been proposed as the main objective the realization of an eyelet device that in addition to meeting the requirements considered essential for this type of articles, It is also simple and economical to manufacture, as well as easy to manufacture. Apply. These objectives have been fully achieved through the eyelet device that will be a reason for description in what continues, whose main characteristics are included in the characterizing portion of claim 1 attached.

In essence, the proposed eyelet device by the invention it consists, as is conventional, in two pieces separated, mutually docking, capable of receiving between the two, as a sandwich, the support material to which they must be fixed, and of which one of the pieces constitutes a base piece and presents a portion of bowl from which a neck emerges cylindrical center prepared to be applied against the second piece during the fixing operation, and of which said second piece acts as a washer, and for that purpose includes a hole center in which the neck of the base piece is located during the application, with the particularity that the washer presents the following features:

- the central hole is polygonal, specifically hexagonal in the embodiment described herein memory although susceptible to other polygonal configurations, bounded by approximately rectilinear edges, particularly with slight undulations;

- the coupling ratio between the washer and the base piece is limited by staggering support perimeter made on the edge of the washer, on the edge perimeter of the bowl part of the base piece, and

- the washer features projecting highlights from its inner face, preferably a highlight on each side of the polygon constituted by the central opening, approximately rectilinear and parallel with the side of the polygon to which it is associated, of sufficient height so that, once the washer is attached to the part as a basis, the highlights constitute a sufficient means of retention by pressure on the support interposed between both pieces.

That way, an eyelet device is achieved extremely effective, whose structural characteristics allow both pieces of it can be easily constructed by a simple injection molding operation of a plastic material suitable.

Description of a preferred embodiment

As mentioned above, the detailed description of the preferred embodiment of the object of the invention, will be carried out in what follows with the help of the attached drawings, through which they are used the same numerical references to designate equal parts or equivalent. Thus, attending to the representations of the various figures, it can be seen that the eyelet device of the The present invention consists of two separate pieces consisting of a base piece 1 and a washer 3. The base piece 1, as is conventional, is constituted by a body shaped as a circular bowl, from which a neck emerges centrally 2 generally cylindrical and predetermined height, internally gap for the determination of an axial through hole intended for constitute the passage opening when the eyelet device has been applied to a laminated support material.

As for washer 3, it consists of one piece of a circular plan, conceived so that it presents a central hole 4 through to accommodate neck portion 2 cylindrical of the base piece 1 when both are mutually coupled to each other, but with the particularity that said hole 4 central washer 3 is polygonal configuration, in particular hexagonal in the present embodiment, delimited by 4a edges approximately rectilinear, although with slight undulations, but in any case smooth and without any other outstanding training. In correspondence with each of the 4th sides of the polygon and at a certain distance from them, it has planned the formation of as many highlights 5, approximately rectilinear and parallel with the respective sides 4a to which associate. These highlights are of a height such that, as seen in the side elevation and sectional representations of the Figures 2 and 3, respectively, protrude substantially with with respect to the edge part 3 of washer. In addition, the edge perimeter that delimits the body of the washer, presents a step formation 6, whose diameter is approximately equivalent to the inside diameter of the perimeter edge of the bowl body of the base piece 1.

With this configuration, it is easy to understand that the coupling between both pieces is especially suitable for securing the eyelet device to any support. To do this, as shown in the representations of Figures 1 and 4, both base pieces 1 and washer 3 fit together in the manner conventional, that is, making the cylindrical neck 2 of the base piece 1 pass through hole 4 of the washer part 3. Under such conditions, as seen more clearly in the Figure 4, the perimeter step 6 formation performed at the edge of the washer 3, comes to rest on the perimeter edge of the bowl body of the base piece 1, thereby limiting the introduction of one body in the other while the highlights 5 establish contact with the internal surface of the body of de bowl of the base piece 1, or at least they are located so next to it exerting pressure on the support previously sandwiched between both pieces. With all this, once riveted the cylindrical neck 2 on the washer part 3, allows said pressure exerted by highlights 5 in each of the positions that occupy, translates into an effective fixation that guarantees the positional maintenance of the eyelet device at the location that has previously been selected for the placement of the same.

It is not considered necessary to make the content of the present description so that an expert in the matter can understand its scope and the advantages of it are derived, as well as carrying out the practical realization of their object.

Notwithstanding the foregoing, and since the description given corresponds only to an example of preferred embodiment, it will be understood that within its essentiality multiple modifications and variations of detail, also included within the scope of the invention, and which in particular may affect features such as the shape, size or manufacturing materials, or any others that do not alter the invention as described and as defined in the following claims.
