Abstract

Toecap for safety footwear, of the type of those that incorporate a piece as an inverted half-shell, of a rigid material capable of withstanding blows without deforming, formally and dimensionally adequate to constitute a protective barrier for the toes of the foot. User, characterized in that on its rear edge are established both upper and lower respective staggered recesses determining a wing along which a series of through holes are established, having foreseen on both sides of said wing are established thin strips of plastic material, with holes formally and dimensionally coinciding with those established on the wing, said strips being left, as well as the wing and the holes thereof covered by a piece like a fin, of a plastic nature and of great flexibility, which extends more beyond said wing in a later sense, presenting the whole set a single-part character.

Description

Toe for safety footwear.

Object of the invention

The present invention relates to a toe, of those intended to be implanted in safety shoes, in order to protect the toes against impacts by different Object types

The object of the invention is to provide a toe cap for safety footwear whose assembly results extremely simple and fast, not needing the use of queues or adhesives for this purpose.

The invention thus falls within the scope of the Industrial safety footwear.

Background of the invention

In the practical scope of the invention, safety shoes incorporate under its cut a toe as a finger protection element, in which leading edge a piece of plastic material is set to prevent the foot from rubbing against the edge defined by said edge.

This piece of plastic material is assembled by gluing with glue, which is a problem that It focuses primarily on the following aspects:

-

He assembly time by operators for these parts is high, with the consequent economic impact that entails

-

Is it is also necessary to wait a certain period of time to queue to dry, after which operators must perform a subsequent manual work.

-

This type of joints have a lifespan that would be desirable to enlarge.

-

By Lastly, the damage to the environment the use of industrial queues.

While this set could already be supplied glued, in order to reduce shoe assembly times, this it is not carried out in practice because the pieces usually kept stored for long periods of time, which would limit the adhesive life.

Description of the invention

The toe for safety footwear that the proposed invention resolves in a fully satisfactory manner the problematic previously exposed, in each and every one of the commented aspects.

For this, the toe that is recommended is will supply already mounted, so that it is not necessary to perform any type of complementary operation other than that of implantation of it under the shoe cut.

More specifically, this toe is constituted from the basic structuring of a toe conventional, based on a rigid material, with the particularity that on its previous and free edge it suffers a reduction of stepped section, determining a perimeter wing on which a series of through holes are conveniently established distributed, so that said "wing" is intended for receive a piece of lightweight and flexible plastic material that remains fixed immovably to the toe piece itself, piece obtained from molding on the toe piece proper, in two phases, a first phase in which set a thin sheet of plastic material on the face internal and external of the stepped wing, also equipped with holes coinciding with those described above, and a second phase in which said sheets are coated as well as the through holes distributed over said wing, by a extremely flexible plastic material, which is decreasing progressively its section in the previous direction.

It is achieved in this way to provide a toe cap with a single piece character and a long service life, which reduces noticeably the assembly times of it on footwear concerned.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows a perspective view of one of the pieces that participate in a shoe toe carried out in accordance with the object of the invention.

Figure 2.- Shows a view similar to that of Figure 1, but in which the toe appears in the final situation mounting

Figure 3.- Shows a detail in section according to the cutting line A-B in figure 2.

Preferred Embodiment of the Invention

In view of the figures outlined you can be seen as the toe for safety footwear that preconiza is constituted, as is conventional, from a reinforcement piece (1) for toes, or toe proper, of a shock resistant material, piece (1) formally and dimensionally adequate to cover the aforementioned fingers, which adopts a configuration by way of semi-inverted bowl, with a bend orthogonal (2) at its lower edge, with the peculiarity that on its leading edge, the wall of the toe itself undergoes a stepped thickness reduction (3), both internal and externally, steps that may or may not be aligned, of so that in the example of practical realization chosen the lower staggering has greater amplitude than staggering upper, both steps defining a wing (4) on which a plurality of through holes (5), which in the practical embodiment example chosen adopt a quadrangular prismatic configuration, but that obviously they could adopt any other configuration without this affects the essence of the invention.

On both sides of the wing (4) defined in the said toe piece itself (1) are established by molding two thin strips (6) of plastic material, equipped of holes formally and positionally coinciding with the holes (5), so that through a second molding phase said wing (4), as well as the sheets (6) and the holes (5) are visible coated by a plastic material, extremely flexible, which extends previously defining a fin (7) elastic, as an extension of the toe piece (1), which prevents rubbing of the foot on the edge of defined rigid material by the mouthpiece of the toe piece itself (1), whose section decreases progressively in the previous direction, so that once this process is finished you get a toe of single character, whose elements are solidly linked to through the holes (5), with a long service life.

Claims (2)

1. Toe cap for safety footwear, of the type that incorporates a piece as an inverted semi-bowl, of a rigid material capable of withstanding shock without deforming, formally and dimensionally suitable to constitute a protective barrier for the toes of the user, characterized in that on its rear edge both staggered recesses determining a wing are established both superiorly and inferiorly along which a series of through holes are established, it being provided that on both sides of said wing thin strips of plastic material, with formal and dimensional holes coinciding with those established on the wing, said strips remaining, as well as the wing and the holes thereof covered by a fin-like piece, of a plastic nature and of great flexibility, which extends beyond said wing in a posterior sense, presenting the whole set a single piece character. 2. Toe for safety footwear, according to claim 1, characterized in that said flap of flexible material has a decreasing thickness in the rear direction.
