Description
A kind of protective footwear refers to a kind of fire fighter's boots especially.
People are engaged in the work of certain risk; need be in waterproof, heat insulationly, anti-skidding, anti-pierce through insulation, anti-knocking pounded and helped bear building-up to close the jail; carry out work under the conditions such as wear-resisting, anti-flexion; need better to satisfy the labour protection footwear of above condition; CN862036711 provides a kind of known " forestry protective footwear "; the protective footwear (see figure 1) generally is made up of belt (1), footwear tube (2), vamp (3), sole (4) footwear root (5), shoe tack (6); lining is generally selected leather for use, and sole is generally selected for use at the bottom of leather or the glue.Its footwear sole construction ecto-entad is (10) at the bottom of the glue successively, anti-piercing through at the middle end (11), along bar (12), fill out carpel (14), the interior end (15), outside line (13) and form along bar (16), its forming technology is in sole waist (see figure 5), (1) first ecto-entad is successively with the middle end (11), along bar (12), group's pin (19), the interior end (15), in the space of sole two edge bars (12) and group's pin (19), fill out carpel (14), be stitched together with interior lines (18), (two) use outside line (13) with (10) at the bottom of the bar again, in the end (11) and be stitched together along bar (12); In the head (see figure 2) of footwear, use earlier along bar (12) and help pin to compress vamp, and use along bar line (16) (10) at the bottom of itself and the glue are stitched together; The structure ecto-entad of its shoe head part vamp is in group's face (8), toe box (9) and the group (7) successively; Its footwear root (5) is followed closely at the sole root by screw (6); Sole design has anti-skid design, decorative pattern is for falling " V " type, the material selection nylon mesh or the steel wire at the end are made in anti-the piercing through, also can add canvas with ox-hide or synthetic leather makes, also can add to depress upper of a shoe and the mold pressing of glue net bottom are combined at mould, because have certain problem on technology and the structure, linear slit technology can not satisfy the requirement of higher protection condition, especially can not satisfy the fire-fighting requirement of shelter, because linear slit structure, group's bear building-up closes complete in along the bar suturing with thread management, although suture passes through water-proofing treatment before use, is immersed in water wearing the midium or long term, flexion repeatedly, friction makes rapid reduction of intensity of line consequently cause group's end cracking, falls to slap etc.Empirical evidence linear slit fire fighter's boots generally can only wear about year half a year, have only through three just losses of the scenes of a fire, its water resistance, insulating properties, phase safe in utilization are just shorter, suture such as permeable causes suture to go mouldy, broken string, therefore and permeable, cause more large-area suture to fracture.And general mould pressing process can not solve abundant combination inherent between which floor sole, in case the area that comes unglued can enlarge rapidly, adhesion is still not high, also can come unglued under strict condition.And bottom structure and technology can not satisfy the higher anti-requirement of piercing through in anti-the piercing through, the end in the general leather, thickness with leather, leather position (at livestock position on one's body) is different and different with getting, it is anti-pierce through power minimum have only 470N, long repeatedly flexion of the time that wears and water logging bubble, its anti-penetration ability can further descend.
The objective of the invention is to, further improve the structure of protective footwear, improve manufacturing process, further improve protective footwear waterproof, heat insulationly, anti-skidding, anti-pierce through, insulation, anti-knocking pound, and group's bear building-up close more firm, wear-resisting, performances such as anti-flexion.
