Benefits of technology

[0019]The invention relates to a one-piece protective toe cap for safety footwear, forming a concave frame consisting of a front wall with connected side walls, the upper edges of which are joined by a concave surface along the profile of the last. The contour or edge of the flange of the toe cap is provided with a recess in order to house a tab and provide comfort, as well as improving the appearance of the footwear (not shown in these documents). The design withstands impact tests of approximately 101.7 to 146.7 Joules (10.4 to 14

Problems solved by technology

The differences lie in the fact that the aforementioned models describe aspects such as the assembly system, some materials of which are composites, and protective inserts in the tip of the foot; even so, they do not define the design and development of a specifi

DETAILED DESCRIPTION OF THE INVENTION

[0037]The toe cap of the present invention has as one of its main characteristics the fact of protecting the five toes.

[0038]To cover and protect the five toes, one must take into account the following points during the design and calculation:

[0039]1. Respect the line of flexure.

[0040]2. Consider the external length of the tab.

[0041]3. The anatomical distribution of the heads with the metatarsals.

[0042]4. The inclusion of the 5 toes.

[0043]5. The displacement of the foot while walking.

[0044]6. Thicknesses of the construction materials of the footwear.

[0045]Analysis of the zone of flexure of the toes, the position of the metatarsal heads and the foregoing considerations let one establish the anatomical aspects of the foot for the development of a protective toe cap in a specific form that covers the five toes and ...

Abstract

The invention relates to a one-piece protective toe cap for safety footwear, forming a concave frame consisting of a front wall with connected side walls, the upper edges of which are joined by a concave surface along the profile of the last. The contour or edge of the flange of the toe cap is provided with a recess in order to house a tab and provide comfort, as well as improving the appearance of the footwear (not shown in these documents). The design withstands impact tests of approximately 101.7 to 146.7 Joules (10.4 to 14.95 kgf−m), leaving clearance of approximately 11 mm to 14 mm in the capped shoe and not only at the tip of the cap.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application claims the benefit of previously filed co-pending Patent Applications, Application No. MX / a / 2007 / 015351 and PCT / MX2008 / 000074.FIELD OF THE INVENTION[0002]The invention addresses the need to protect a worker who is performing a productive activity in industry, a one-piece toe cap has been designed for industrial protective footwear in which said toe cap is specifically designed to the protection of the five digits of the foot against impact and crushing by falling objects. The invention relates to a one-piece toe cap for safety footwear that forms a concave 180° frame that houses an internal cavity supported by a horizontal interior flange that covers the entire internal part of the perimeter of the toe cap 5 to 7 mm in width, the concave frame is composed of a front wall with side walls connected to both sides and whose upper edges are joined by a concave surface following the profile of the last; the toe cap is pre...
