Benefits of technology

The present invention relates to impact resistant structures that provide both sports and military / police protective gear. The structures have a unique middle layer made of a deformable, polymer-based microlattice damping layer and a semi-rigid, polyurethane honeycomb lattice dissipating layer. The microlattice layer uses a three-dimensional network of hollow nanotubes to damp impact forces. The honeycomb layer acts as a constraining layer to improve the damping characteristics of the microlattice. These structures provide superior protection against impacts and have become popular in various sports and military applications.

Problems solved by technology

The principal problem to be solved in designing such garments is that diverse materials need to be utilized in connection with the foregoing capabilities.

Embodiment Construction

[0023]Referring to FIG. 1, an exemplary impact resistant breastplate structure 10 comprises a rigid, shock-deflecting outer layer 11, below which is a deformable, polymer-based microlattice shock-damping layer 12, below which is a semi-rigid, polyurethane honeycomb lattice dissipative layer 13, below which is a lower shock-absorbing fabric layer 14.

[0024]As shown in FIG. 2A, the microlattice layer 12 comprises a three-dimensional network of hollow nanotubes, preferably having tube diameters less than 1 mm. The nanotubes microscopic structure is depicted in FIGS. 2B and 2C, in which the microlattice is under increasing compression, with deformation progressing from incipient buckling at the nodes 15 to more advanced buckling 16. The buckling at the nanotubes' nodes damps impact forces, and the extremely small aspect ratio of the nanotubes' wall thickness to their diameter enables nearly full deformation recoverability.

[0025]FIG. 3 depicts the semi-rigid, polyurethane honeycomb lattic...

Abstract

A multi-layer composite structure is conformable to the contours of the body parts for which protection is required. The composition structure contains a rigid shock-deflecting outer layer, two semi-rigid shock-damping and shock-dissipating middle layers, and a pliable shock-absorbing lower layer. In one embodiment, the structure is designed for impacts associated with contact sports, such as football, hockey and lacrosse. In another embodiment, the structure is designed for military / police applications, in which impacts can be blunt forces, from weapons such as clubs, or penetrative forces, from knives, bullets or shrapnel.

Description

RELATION TO OTHER APPLICATIONS[0001]This application claims the benefits of the filing date of U.S. Provisional Patent Application No. 62 / 407,204, filed Oct. 12, 2016, the disclosure of which is incorporated herein by reference. The present invention is also related to this inventor's U.S. Pat. No. 9,067,122 B2, “Protective Athletic Garment and Method,” which is incorporated herein in its entirety.FIELD OF INVENTION[0002]The present invention relates to the field of garments adapted to protect a wearer's body from impacts associated with contacts sports and / or military / police activities.BACKGROUND OF THE INVENTION[0003]Protective garments for sports, military and police uses have evolved in the direction of becoming lighter, stronger, more mobile, and more wearable. Optionally, the structures comprising such protective garments should be capable of deflecting impact forces, damping their impact, dissipating such forces, absorbing them, and blocking penetration through to the wearer'...
