Abstract

Abstract A human body protector comprising a front layer and a rear layer. In this protector, each layer is comprised of a plurality of segments having a regular hexagon shape and arranged by placing circumferential edges of adjacent segments in contact with each other in a state wherein spaces between the adjacent segments are substantially eliminated, and joining lines between the adjacent segments of one layer are covered by the segments of the other layer, and through apertures at the joining points, existing because joining lines of the segments of one layer overlap the joining points of another layer, are closed by a retaining members. The construction of the protector of the present invention provides an excellent protection against penetration of the protector by a sharp pointed blade, such as an ice pick.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 229 words
A human body protector having a flexibility making said protector capable of fitting a human body, characterized in that said protector is comprised of a front layer consisting a group of segments (P 1 ) of blade-proof plate having a plurality of connecting apertures (1) and spread over the body by placing circumferential edges of adjacent segments in contact with each other in a state wherein spaces between the adjacent are substantially eliminated, and a rear layer consisting of another group of segments (P 2 ) of blade-proof plate made and spread over the body in the same manner as the segments (P 1 ), and each of said segments constituting both layers being superimposed in a shifting state such that each segment of one layer can cover joining lines (L 1 or L 2 ) between each segment of the opposite layer, respectively, the front layer and the rear layer being connected in a state wherein they are capable of moving slightly relative to each other by inserting retaining members (6) into each connecting aperture (1) at a position in which it corresponds with an aperture in the other layer; and the other retaining members (7) being inserted at cross points of joining lines (L 1 ) of the front layer and the joining lines (L 2 ) of the rear layer existing when both layers are superimposed.
Claim 2
Dependent Claim 229 words
A human body protector having a flexibility making said protector capable of fitting a human body, characterized in that said protector is comprised of a front layer consisting a group of segments (P 1 ) of blade-proof plate having a plurality of connecting apertures (1) and spread over the body by placing circumferential edges of adjacent segments in contact with each other in a state wherein spaces between the adjacent are substantially eliminated, and a rear layer consisting of another group of segments (P 2 ) of blade-proof plate made and spread over the body in the same manner as the segments (P 1 ), and each of said segments constituting both layers being superimposed in a shifting state such that each segment of one layer can cover joining lines (L 1 or L 2 ) between each segment of the opposite layer, respectively, the front layer and the rear layer being connected in a state wherein they are capable of moving slightly relative to each other by inserting retaining members (6) into each connecting aperture (1) at a position in which it corresponds with an aperture in the other layer; and the other retaining members (7) being inserted at cross points of joining lines (L 1 ) of the front layer and the joining lines (L 2 ) of the rear layer existing when both layers are superimposed.
Claim 3
Dependent Claim 82 words
A human body protector according to claim 1, characterized in that said segments (P 1 ) and said segments (P 2 ) are provided with at least one aperture (2) through which air can pass, respectively, and said segments (P 1 ) and/or said segments (P 2 ) include at least one protrusion for maintaining a space between said segments (P 1 ) and said segments (P 2 ) arranged on opposing surfaces of both segments (P 1 and P 2 ).
Claim 4
Dependent Claim 34 words
A human body protector according to claim 1, characterized in that said segments (P 1 ) and said segments (P 2 ) have a shape of a regular hexagon and are the same size.
Claim 5
Dependent Claim 27 words
A human body protector according to claim 1, characterized in that said retaining members (6 and 7) include a through hole arranged at a center position thereof.
Claim 6
Dependent Claim 321 words
A human body protector having a flexibility making said protector capable of fitting the human body, characterized in that said protector is comprised of a front layer consisting of a group of segments (P 3 ) of blade-proof plate having a plurality of connecting apertures (1) and spread over the body by placing circumferential edges of each segment in contact with each other in a state wherein spaces between adjacent segments are substantially eliminated, and a rear layer consisting of another group of segments (P 2 ) of blade-proof plate having a plurality of connecting apertures (1) and spread over the body by placing circumferential edges of each segment in contact with each other in a state wherein spaces between adjacent segments are substantially eliminated; and each segment constituting both layers being superimposed in a shifting state such that each segment of one layer can cover joining lines (L 1 or L 2 ) between each segment of the opposite layer, respectively; a central rib (4) protruding from a front surface of the segment (P 3 ) of the font layer being provided at a position of the segment (P 3 ) at which it can cover the joining lines (L 2 ) between adjacent segment (P 2 ) of the rear layer, and a circumferential rib (4') protruding from the outside surface of the segments (3) being provided on circumferential edges of the segments (3); the font layer and the rear layer being connected in a state wherein they are capable of moving slightly relative to each other by inserting retaining members (6) into each connecting aperture (1) at a position in which it corresponds with an aperture in the other layer; and the other retaining members (7) being inserted at cross points of joining lines (L 1 ) of the front layer and joining lines (L 2 ) of the rear layer are existing when both layers are superimposed.
Claim 7
Dependent Claim 321 words
A human body protector having a flexibility making said protector capable of fitting the human body, characterized in that said protector is comprised of a front layer consisting of a group of segments (P 3 ) of blade-proof plate having a plurality of connecting apertures (1) and spread over the body by placing circumferential edges of each segment in contact with each other in a state wherein spaces between adjacent segments are substantially eliminated, and a rear layer consisting of another group of segments (P 2 ) of blade-proof plate having a plurality of connecting apertures (1) and spread over the body by placing circumferential edges of each segment in contact with each other in a state wherein spaces between adjacent segments are substantially eliminated; and each segment constituting both layers being superimposed in a shifting state such that each segment of one layer can cover joining lines (L 1 or L 2 ) between each segment of the opposite layer, respectively; a central rib (4) protruding from a front surface of the segment (P 3 ) of the font layer being provided at a position of the segment (P 3 ) at which it can cover the joining lines (L 2 ) between adjacent segment (P 2 ) of the rear layer, and a circumferential rib (4') protruding from the outside surface of the segments (3) being provided on circumferential edges of the segments (3); the font layer and the rear layer being connected in a state wherein they are capable of moving slightly relative to each other by inserting retaining members (6) into each connecting aperture (1) at a position in which it corresponds with an aperture in the other layer; and the other retaining members (7) being inserted at cross points of joining lines (L 1 ) of the front layer and joining lines (L 2 ) of the rear layer are existing when both layers are superimposed.
