Protective toe cap for industrial footwear

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...

AI Technical Summary

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 14.95 kgf−m), leaving clearance of approximately 11 mm to 14 mm in the capped shoe and not only at the tip of the cap. Therefore one objective of the invention is to start from a last obtained by anthropometric study of the worker wearing the safety and protective footwear, currently being filed for a patent by the same applicant of the present invention, and design, calculate and elaborate a one-piece toe cap to protect the five toes of the foot, defining heights, widths, depths and elements for balanced distribution of impact forces.

[0021]A further object is to develop a one-piece toe cap that effectively protects the five toes with the maximum possible comfort, not interfering with the free flexing and not promoting deformation of the foot, being ergonomical in accordance with the morphology of the worker wearing the safety and protection footwear.

[0022]A further object is to develop a one-piece toe cap or effective protector of the five toes for adequate use as individual protective equipment to reduce the economic and human costs occurring in the country from injuries to the feet of the workers wearing this product.

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 specific toe cap based on an anthropometric study and the parts of the foot to be protected, considering the ergonometric and functional aspects in various activities of the user, nor do they give a rule for evaluation of impact and compression results that they fulfill.
