Abstract

"Constructive disposition introduced in pliers", of the type that may be utilized for cutting of nails and/or cuticles, and that comprises that its gripping handles (1) are specially produced by injection, where the same show a structure (3) of the bicomponent type;said structure (3) of the gripping handle (1), comprises two regions, being one external region (4) preferably produced in Santoprene, and another internal region (5), constitutive of the body (6) of the pliers, and that is manufactured in high resistance Nylon added with thirty per cent (30%) of fiberglass.

Description

/ CONSTRUCTIVE ARRANGEMENT INTRODUCED IN CLAMPS This description refers to a utility model patent application, which deals with a new constructive arrangement that is introduced in clamps of the type that are normally used to cut the nails and / or the cuticle. As is generally known, the clamps for cutting the nails and / or the cuticle are normally they construct by means of the assembly of two symmetrical metal parts, which are articulated at a common intermediate point, each of the metal parts have clamping areas and ends provided with cutting edges. 15 In another type of more modern clamps, the two main parts that make up the instrument are not completely metallic, but each of the handles carries a portion previously obtained by injection of material, which receives in its internal part an insert corresponding to the front end, where the corresponding cutting edge is located. This last type of pliers presents a series of advantages when compared with the model above, since only a small part of its structure is really made of metal. The use of injected material as part of the structure of the tweezers, in what refers to the grip area of their handles, allows obtaining less expensive, lighter and more reliable parts. Within this context, this constructive arrangement was developed to be introduced into the tweezers and is especially characterized by the fact that the injected portion of each of the two parts that comprise the tweezers, shows a substantially innovative construction. Next, the clamps that are the subject of this utility model patent application will be described in detail, with reference to the following drawings: Figure 1 illustrates a flat view of the clamps covered by this patent; Figure 2 illustrates a side view of the clamps, taken in accordance with the direction indicated by arrow A of Figure 1; and Figure 3 illustrates a sectional view of the clamps, taken in accordance with the direction indicated by the cut line B-B of Figure 1. In accordance with what is illustrated by the figures listed above, the constructive arrangement introduced in the clamps of the present is characterized by the fact that anticipate that the grip handles (1) of the clamps (2) are especially produced by injection, which allows them to have a structure (3) of bicomponent type. The structure (3) of the grip handle (1), as illustrated in the figures that make up this utility model patent, comprises two regions, which despite being completely integrated, can be clearly defined thanks to the differentiated nature of the structure. the materials used, that is, an external region (4) preferably produced from Santoprene material and another internal region (5), constituting the body (6) of the tweezers and which is made of high strength nylon added with 30% fiber of glass. The interconnection of the two parts that make up the body (6) of the clamps (2) is anticipated to be constituted by a rivet (7), which can be produced from stainless steel or even from nylon, welded by interference. The pincer model used to illustrate this constructive arrangement depends on a pair of spring leaves (8), each completely inserted in the structure of the corresponding internal region (5) that integrates the body (6); the leaves (8) are positioned so that they are opposite each other, as a means of resistance calibrated to the closure of the clamps. The tweezers of the present have grip handles (1) molded by injection of high technology, which constitutes an injection process using special equipment for exclusive or dedicated use, by means of which two or more materials of colors and with differentiated characteristics are used. . Within this context, the clamps proposed in the present depend on the physical particularities of two different materials, which make up its body, namely nylon / fiberglass, which constitutes the body (6) of the tweezers and Santoprene, which occupies the external region (4) of the holding handle. The first material gives resistance to the tweezers, notably with regard to rigidly and permanently retaining the inserts that include the cutting edges and the spring sheets and, the second material, acts as a means to improve the ergonomics of the tweezers, which is obtained according to the anti-slip characteristics to ensure a better grip of the instrument. It is worth emphasizing that the pincer model illustrated in this utility model patent application can be subject to an aesthetic adaptation, without escaping from the scope of the protection sought to be related to the constructivity presented herein.

Claims (1)

CLAIMS;

1. Constructive arrangement introduced in clamps of the type used to cut the nails and / or the cuticle, characterized in that the clamping handles (1) for the clamps (2), are specially produced by injection, with the same structure (3) of bicomponent type; the structure (3) of the holding handle (1) comprises two regions which are: an external region (4), preferably produced from Santoprene, and another internal region (5), constitutive of the body (6) of the forceps and manufactured from high strength nylon added with thirty percent (30%) fiberglass; it is anticipated that the interconnection of the two parts that make up the body (6) of the clamps (2) is a rivet (7), which may be made of stainless steel or even in nylon welded by "interference; the clamps have a pair of spring leaves (8), each inserted completely in the structure of the corresponding internal region (5) that integrates the body (6); the leaves (8) are positioned so that they are opposite each other as a means of resistance calibrated to the closure of the clamps.
