Description
Technical field
The utility model is relevant with footwear, is meant a kind of safety toes especially, and it is light and handy to have splendid mechanical strength and weight.
Background technology
Press, commercially available general safety toes is made by metal material such as iron and steel, though have engineering properties such as splendid impact strength and compressive resistance, so heavier because of weight, cause easily that the wearer's is handicapped, the safety toes that recently existing fibre reinforced resin (fiber reinforced plastic) is made comes out, improve the too heavy shortcoming of aforementioned weight effectively, right its mechanical strength but is difficult to reach the standard of safety test, particularly relevant impact strength aspect, commercially available safety toes is generally not enough, and its security causes anxiety.
The utility model content
Supervise in above-mentioned shortcoming, main purpose of the present utility model is promptly providing a kind of safety toes, its have splendid mechanical strength and weight light and handy.
Edge is to take off purpose for before reaching, safety toes provided by the utility model is to include a basic unit and at least one strengthening course, wherein this basic unit is the toe-cap shape, and it is made by the fibrous reinforcement thermosetting resin, this strengthening course is then made by thermoplastic fibre impregnation thermosetting resin, and be coated on the some of this substrate surface at least: perhaps, this basic unit includes the plural layer fiber, this strengthening course then is located between this plural layer fiber, thus, this safety toes have splendid mechanical strength and weight light and handy.
Wherein this strengthening course is the some that is coated on this substrate surface at least.
Wherein this strengthening course is the outer surface that is coated on this basic unit.
Wherein this strengthening course is the inner surface that is coated on this basic unit.
Wherein this strengthening course is outer surface and the inner surface that is coated on this basic unit.
Wherein this basic unit is made by plural layer fibrous reinforcement thermosetting resin, and this strengthening course then is located between the plural layer fiber.
Wherein the fiber of this basic unit can adopt glass fibre, carbon fiber, boron fibre, and aromatic series polyamide fiber.
Wherein the fiber of this basic unit is for long fine.
Wherein the thermoplastic fibre of this strengthening course is weaved cotton cloth and can be adopted anti-dragon or polyester fiber made.
Wherein the fusing point of the thermoplastic fibre of this strengthening course is the best with 160-260 ℃.
Wherein to weave cotton cloth with the red Buddhist nun of 900-4800 be the best to the thermoplastic fibre of this strengthening course.
Wherein this strengthening course is made by thermoplastic fibre adhesive-bonded fabric impregnation thermosetting resin, and this adhesive-bonded fabric is long-pending heavy with 10～100g/m
2Be the best.
Description of drawings
In order more to understand characteristics of the present utility model place, below in conjunction with three preferred embodiments and cooperation
Description of drawings is as follows, wherein:
Fig. 1 is the stereogram of the utility model first preferred embodiment.
Fig. 2 is the cutaway view of Fig. 1 along the 2-2 direction.
Fig. 3 is the stereogram of the utility model second preferred embodiment.
Fig. 4 is the cutaway view of the utility model the 3rd preferred embodiment.
The specific embodiment
See also Fig. 1, Fig. 2, the safety toes 10 that the utility model first preferred embodiment is provided is to include a basic unit 12, and two strengthening course 18 be located at respectively this basic unit 12 in, outer surface 13,14, form a similar sandwich structure, wherein this basic unit 12 is the toe-cap shape, be made by the fibrous reinforcement thermosetting resin, fiber can adopt and be not limited to glass fibre according to actual demand, carbon fiber, boron fibre, or aromatic series polyamide fiber, it is the Ke Weila fiber (KEVLAR) that industry is commonly called as, and all adopt long fine (continuous fiber), thermosetting resin then can adopt and be not limited to epoxy resin, phenol resin etc.; 18 of these strengthening courses are made by the thermoplastic fibre impregnation thermosetting resin of weaving cotton cloth, this thermoplastic fibre is weaved cotton cloth and can be adopted and be not limited to anti-dragon (nylon) or polyester fiber (polyester fiber), its fusing point is the best with 160～260 ℃, and yarn is the best with 900～4800 red Buddhist nuns then.
Reinforcement by this two strengthening course 18, can effectively strengthen the mechanical strength of this safety toes 10, particularly impact strength will significantly improve, make this safety toes 10 can exceed the standard of safety test really, not only security does not have anxiety, weight is more light than conventional steel safety toes made of iron, can effectively improve the shortcoming of known structure, thereby reach the purpose of this utility model.
During actual the manufacturing, the position that is provided with of this strengthening course has multiple variation, being not limited to above embodiment carries, for example shown in Figure 3, be the safety toes 20 that the utility model second preferred embodiment is provided, be to include a basic unit 22 and a strengthening course 24, wherein this strengthening course 24 only is coated on the leading edge portion of these basic unit's 22 outer surfaces 23, cover this and partly belong to the bending band, its mechanical strength is relatively poor, needs the event of reinforcement especially.
And for example shown in Figure 4, it is the safety toes 30 that the utility model the 3rd preferred embodiment is provided, roughly the same with aforementioned first preferred embodiment, also include a basic unit 32, and 2 first strengthening course 35 be located at respectively this basic unit 32 in, outer surface 33,34, and this basic unit 32 is made by two layers or more (present embodiment is eight layers) fibrous reinforcement thermosetting resin 321, different persons are, more be folded with one second strengthening course 36 between the multi-layer fiber layer 321 of this basic unit 32, this second strengthening course 36 is made by thermoplastic fibre adhesive-bonded fabric (non-woven) impregnation thermosetting resin, during actual the manufacturing, this thermoplastic fibre adhesive-bonded fabric long-pending heavy then with 10～100g/m
2Be the best, this structure will improve the impact strength of safety toes 30 more significantly, thereby reach the utility model argument.
In fact, as long as can improve the engineering properties such as impact strength of safety toes, no matter be the front that strengthening course is arranged at toe-cap, or only be arranged at one of the inner surface of basic unit or outer surface, or be located in the centre of basic unit, diverse location is provided with the strengthening course of multilayer even, is the utility model claim and contains.
In sum, the utility model is by well-designed basic unit, and the combination of strengthening course, form one and have excellent mechanical strength and lightweight safety toes, its unitary construction really at first creating and tool enhancement effect, should meet the condition of novel patent, so apply for a patent in accordance with the law.
