AI Technical Summary

Technical Problem

Conventional over-trousers face issues such as time-consuming and cumbersome donning and doffing procedures, limited freedom of movement, susceptibility to insulation loss, lack of user-adjustable ventilation control, and limited integration of multilayer techniques, while also requiring complex waist or leg adjustment systems.

Method used

A modular and multifunctional over-trouser garment design featuring two trouser leg portions with longitudinal openings, flaps covering the buttocks region, and a waistband assembly, allowing rapid donning and doffing, adjustable insulation and ventilation, and access to underlying garment pockets, while maintaining ergonomic fit and aesthetic variety.

Benefits of technology

The design enables quick and comfortable donning and doffing without removing footwear, provides adjustable insulation and ventilation, enhances freedom of movement, and integrates multilayer techniques for enhanced protection and comfort, while being compatible with industrial production methods.

Abstract

An insulating and / or protective over-trouser garment for quick change, comprising two trouser leg portions not completely joined to each other, each trouser leg portion having a longitudinal rear opening configured for relative separation or overlap, with a limited number of non-permanent fastening means of diverse types, including hybrid systems, configured for rapid closing and opening and optional adjustment of said separation / overlap; at least two flaps arranged to overlap at least partially the trouser leg portions and to cover at least partially the buttocks region; and a waistband assembly configured to close upon itself at the rear. The cooperative arrangement of these elements, as a result of the particular shape of the elements and the joints between them, provides insulation and / or protection while maintaining ergonomic freedom of movement, enabling scalable manufacture through processes similar to those used for conventional trousers, and offering multipurpose applicability in fashion, workwear, and outdoor contexts.
