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

The present description relates to a patent application for a consumer article which concerns a new constructive device introduced into nail scissors, as is normally used for cutting nails and/or cuticles.

As is well known, scissors for cutting nails and/or cuticles are normally constructed by assembling two symmetrical metal parts, hinged at a common point, each of which is provided with a handle and an end containing the cutting edge.

Another more modern type of nail scissors is that the two main parts that make up the instrument are not completely made of metal, but each of the handles has an injection-molded part that has an insert inside that corresponds to the front end where the corresponding cutting edge is located.

This latter type of scissors has a number of advantages compared to the older one, since only a small part of its structure is actually made of metal.

The use of an injection molded material as part of the construction of the scissors, particularly in their handle area, allows the production of cheaper, lighter and more reliable parts.

In this context, the present constructive device incorporated in a pair of nail scissors was developed, which is characterized in particular by the fact that the injection-molded part of each of the two parts that make up the scissors has a substantially innovative construction.

The nail scissors which are the subject of this patent application for a utility article are described in detail below, with reference to reference is made to the drawings below, in which:

Fig. 1 shows a plan view of the nail scissors which are the subject of this patent;

Fig. 2 shows a side view of the scissors according to the patent, as indicated by the arrow A in Fig. 1; and

Fig. 3 shows a section of the patented scissors, as indicated after section B-B in Fig. 1.

As shown in the above figures, the structural arrangement of a pair of nail scissors described here is characterized by the fact that it is intended to manufacture the handles 1 of the nail scissors 2 specifically by injection molding, which allows them to have a two-component structure 3.

The structure 3 of the handles 1, as shown in the figures which are part of the utility model subject of this patent, comprises two regions which, although completely integrated, can be clearly defined due to the different nature of the materials used, i.e. an external region 4, preferably made of Santoprene, and another internal region 5 which forms the body 6 of the nail scissors and which is made of high-strength nylon with an addition of 30% glass fibres.

A rivet 7 is provided to connect the two parts that form the body 6 of the nail scissors 2 in question, which rivet can be made of stainless steel or interference-welded nylon.

The embodiment of a nail scissors as used for the illustration of the present constructive device has a pair of spring leaves 8, each of which is completely inserted into the structure of the corresponding inner region 5 integrally forming the body 6. These spring leaves 8 are arranged so as to oppose each other with a calibrated resistance to the closing of the nail scissors.

In the nail scissors described here, the handles 1 are formed by high-tech injection molding, which is an injection molding process with the use of targeted equipment and which requires the use of two or more materials with different colors and properties.

In this context, the nail scissors proposed here rely on the physical properties of two different materials that make up their body, i.e. nylon/fiberglass, which make up the body 6 of the nail scissors, and Santoprene, which occupies the outer region 4 of the handles.

The first material gives the nail scissors resistance, especially in terms of the firm and definitive fastening of the inserts containing the cutting edges and the spring leaves, and the second material improves the ergonomics of the nail scissors due to the non-slip properties, which give the instrument a better "grip".

It should be stressed that the nail scissors embodiment shown in this patent application for a utility object can be subject to aesthetic adaptations without thereby escaping the purpose of the intended protection, which relates to the design presented here.

Claims (1)

1. Structural device inserted into a nail scissors of the type that can be used for cutting nails and/or cuticles, characterized in that the handles (1) of the nail scissors (2) are made in particular by injection molding, having a structure (3) consisting of two components; in that said structure (3) of the handle (1) comprises two regions, an external region (4), preferably made of Santoprene, and another, internal region (5) which forms the body (6) of the scissors and which is made of high-strength nylon with an addition of 30% glass fibers; in that for connecting the two parts which form the body (6) of the nail scissors (2) in question, a rivet (7) is provided, which can be made of stainless steel or of interference-welded nylon; and that the present nail scissors are provided with a pair of spring leaves (8), each of which is completely inserted into the corresponding structure of the inner region (5) forming the body (6), said spring leaves (8) being arranged so as to oppose each other with a calibrated resistance to the closing of the nail scissors.
