(1) Field of the Invention
This creation is related to safety toe cap for work shoes, especially related to a kind of multi-axial weaving angle, multi-dimensional structure and capable of increasing strength for work shoes with safety toe cap base material structure.
(2) Description of the Prior Art
According to known work shoes safety toe cap habitually used, it is by using mixed material such as fiber glass or thermoplastic resin etc. and molding by place it in a mold by hot press or thermoform. Because the strength is limited and not enough elongation, it is unable to be made as high strength safety toe cap. Consequently there is a kind of composite lamination molding material 10 as per
The main objective of this creation is to provide a kind of safety toe cap for work shoes that can provide another kind of molding material for increase safety toe cap strength, to make safety toe cap possess high strength structure.
To achieve the above mentioned objective, this creates a kind of safety toe cap base material structure for work shoes. It is including at least 3˜5 layers of fiber layer comprised by method of pressing. And, each of these fiber layers is formed by molding materials using strengthen fiber glass or thermoplastics resin filament weaving at four kinds of different angles. To provide a kind of multi-axial and multi-dimensional structure safety toe cap base material structure, results in better strengthen effect and safety.
BRIEF DESCRIPTION OF THE DRAWINGS
As indicated by
Each of such fiber layer 22, 24, 26 are formed by molding material using strengthen fiber glass or thermoplastic resin filament weaving at four kinds of different angles. Including one first filament 221 or 241, 261, one second filament 222 or 242, 262, one third filament 223 or 243, 263 and one fourth filament 224 or 244, 264 to present at a predetermined angle, their angle ranging from 0˜360 degree. Please refer to
The third filament 223 is by way of 45 degree to each of the first filament 221 and second filament 222, during weaving one filament is positioned above first and second filament 221, 222, another filament is positioned below first and second filament 221, 222, arrange at cross overlapping position between first and second filament 221, 222.
The fourth filament 224 is similarly by having 45 degree angle to each of the first filament 221 and second filament 222, and is cross perpendicular with the third filament 223. During weaving one filament is similarly positioned above the first and second filament 221, 222, and another filament is positioned below first and second filament 221, 222, arrange at cross overlapping position between first and second filament 221, 222, moreover during weaving it winding through the third filament 223. From the above safety toe cap base material structure 20, because each of such fiber layer 22, 24, 26 are plied up with different angle, and the weaving that comprise the fiber layer 22, 24, 26, their first, second, third and fourth filament 221˜224, 241˜244, 261˜264 are weaving by winding through different angle and the links are binding tightly. So the safety toe cap base material structure 20 for this invention has multi-axial and multi-dimensional fiber layer structure. Therefore it has the effect of sustain various reaction force from different angle, in another word, better strengthen effect and better safety can be safety can be produced, thoroughly eliminate the deficiency of habitually used toe cap.
We must provide explanation, that weaving by different angle of filaments, no matter what the angle is between first and second filament, and the angle that the third and fourth filament is winding through the first and second filament, as long as the base material is pile together by multi-layers of fiber layers, and each fiber layer is formed by weaving multiple filament and different angles, having multi-axial direction and multi-dimensional fiber layer structure, providing same effect as the actual invention, they are also belong to same technical category as this invention.
Sum up the description above, this invention of work shoes safety toe cap base material structure, its entire structure is truly the first invention and posses practical effect, it should have conform to the invention pattern requirement. We earnestly request examining commissioner to examine in detail, and grant us the pattern at the earliest.
Claims
