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

"CONSTRUC IVE DISPOSITION INTRODUCED IN PLIERS"

This report refers to a patent application of utility model that deals with a new constructive disposition introduced in pliers of the type normally used for the cutting of nails and/or cuticles.

As is of the general knowledge the pliers for cutting of nails and/or cuticles are normally constructed through the mounting of two symmetrical metallic parts, which are articulated in a common intermediate point, each one of which having areas of gripping and extremities provided with cutting edges.

Another type of more modern pliers comprises that the two main parts which constitute the instrument are not entirely metallic, being anticipated, in each one of the handles, a portion obtained by injection of material, that receives in its inner part an insert that corresponds to the anterior extremity where is located the corresponding cutting edge. This latter type of pliers presents a series of advantages if compared to the older model, since only a small part of its structure is actually made of metal.

The use of injected material as part of the structure of the pliers, notably in what refers to the area of gripping of its handles, allows the obtainment of less expensive, lighter and more reliable pieces. Within this context was developed this constructive disposition introduced in pliers, which is specially characterized by the fact that the injected portion of each one of the two parties that compose the pliers shows a substantially innovative construction.

Next, the pliers object of this patent application of utility model will be described in detail with reference to the below listed drawings: the figure 1 illustrates a flat view of the pliers object of this patent; the figure 2 illustrates a lateral view of the subject pliers, that is taken according the direction indicated by the arrow A of figure 1; and the figure 3 illustrates a cutting section view of this pliers, that is taken according to the direction indicated by the B -

B cutting line of figure 1. According to what is illustrated by the above listed figures, the constructive disposition introduced in pliers herein commented, it is characterized by the fact of anticipating that the gripping handles (1) of the pliers (2) , are specially produced by injection, that allows that the same present a structure

(3) of the bi-component type.

The structure (3) of the gripping handle (1), as illustrate the figures that integrate this patent of utility model, comprises two regions, that in spite of being entirely integrated, may be clearly defined due to the differentiated nature of the utilized materials, that is, an external region (4) produced preferably in Santoprene material, and another internal region (5), constitutive of the body (6) of the pliers and that is manufactured in high resistance nylon added with 30 % of fiberglass.

Interconnecting the two pieces that integrate the body (6) of this pliers (2) it is anticipated a rivet (7), which may be produced in stainless steel, or even in Nylon welded by interference.

The model of pliers utilized to illustrate this constructive disposition, relies on a pair of spring blades (8), each one entirely inserted in the structure of the corresponding internal region (5) that integrates the body (6) said blades (8) are positioned so as to oppose themselves to each other as a means of calibrated resistance to the closing of the pliers. The pliers herein dealt has its gripping handles (1) molded by injection of high technology, that constitutes an injection process that employs special equipment of dedicated use, that provide the utilization of two or more materials in colors and with differentiated characteristics.

Within this context, the herein proposed pliers relies on the physical particularities of two different materials, which integrate its body, namely, the Nylon/fiberglass that constitute the body (6) of the pliers, and the Santoprene, which occupies the external region (4) of the gripping handle.

The first material gives resistance to the pliers, notably in what refers to retaining in a firm and definitive way the inserts that include the cutting edges and the spring blades, and the second material, actuates as a means to improve the ergonomy of the pliers, what is obtained in function of the anti-skidding characteristics that assures a better grip to the instrument.

It is worthwhile to emphasize that the model of pliers illustrated in this application for patent of utility model may be target of adequation of esthetic order, without one escaping from the scope of the intended protection that is related to the constructivity herein presented.

Claims

1. "CONSTRUCTIVE DISPOSITION INTRODUCED IN PLIERS", of the type that may be utilized for cutting of nails and/or cuticles, characterized by the fact of comprising that the gripping handles (1) of the pliers (2), are specially produced by injection, where the same a structure (3) of the bi-component 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; interconnecting the two pieces that integrate the body (6) of this pliers (2) is anticipated a rivet (7), that may be produced in stainless steel, or even in Nylon welded by interference; the subject pliers has a pair of spring blades (8), each one entirely inserted in the structure of the corresponding internal region (5) that integrates the body (6), said blades (8) are positioned so as to oppose each other as a means of calibrated resistance to the closing of the pliers.
