Description

[Detailed Description of the Invention] The present invention relates to safety work shoes used at work sites and the like.

Some safety work shoes are constructed to protect the toes and ankles of the shoe wearer from impact.

Conventional safety work shoes of this type have a toe core steel plate built into the toe area of the shoe upper, and a toe protector made of a steel plate or hard plastic plate that is molded to cover the shoe wearer's foot. Many have a structure in which they are attached over the skin.

In safety work shoes with this structure, the lace protector is attached to overlap the outer surface of the upper, so the lace protector may wobble on the upper while walking, or the edge of the lace protector may If the edge gets caught in an obstacle, if debris gets caught or entangled with the same edge, or if dirt gets stuck in the gap between the instep protector and the upper, it may cause problems when walking or wearing the shoes. The disadvantage is that it tends to be uncomfortable to wear.

The present invention aims to provide a safety shoe that can overcome the above-mentioned conventional drawbacks by incorporating a lace protector into the shoe upper.

Embodiments of the present invention will be described below based on the drawings. 1 is a pair of short boots, 2 is the upper of the pair of boots 1, and the inner part is the part that covers the foot of the shoe wearer and the part that covers the toe. It has a double structure in which a deck 3 and an outer deck 4 are overlapped, and the lower peripheral edge of the outer deck 4 is hooked into the sole 5.
Reference numeral 6 denotes a toecap steel plate built into the toe portion of the upper 2, and is interposed between the inner deck 3 and the back upper 7 lining the inner upper 3. Reference numeral 8 denotes a lace protector built into the part of the deck 2 that covers the lace of the shoe wearer. It is made of steel plate or hard plastic and is formed into a shape that covers the lace of the shoe wearer. It is interposed between the upper skins 3, and the tip edge 9 of the shank protector 8 is stacked on the toecap steel plate 6 via the inner upper skin 3. Reference numeral 10 denotes a cushion material such as sponge, which is polymerized by adhering to the inner surface of the lace protector 8 with an adhesive, and has a protruding portion 12 that protrudes beyond the rear edge 11 of the lace protector 8. Reference numeral 13 denotes a cover that wraps the lace protector 8 and the cushion material 10 between the outer shell 4 and the inner shell 3. Its periphery is sewn to the outer shell 4 as shown by the seam 14, and the lace protector 8 and The cushion material 10 is supported between the outer shell 4 and the inner shell 3 so as not to shift.
15 is a seam where the peripheral edge of the outer shell 4 is sewn to the inner shell 3.

As mentioned above, this invention has a lace protector built into the upper of the shoe, so the lace protector does not rattle on the upper of the shoe while walking, or the edge of the lace protector gets caught on an obstacle. Or, debris may get stuck or entangled on the edge of the shoe, or dirt may become clogged in the gap between the instep protector and the upper of the shoe, which may impair walking or the comfort of wearing the shoe. Never. In addition, we have provided a sponge or other cushioning material that polymerizes inside the lace protector and protrudes beyond the rear edge of the lace protector, so if the part of the shoe upper that covers the lace of the foot receives an impact, the cushion material will This cushions the impact and protects the foot, and if the shoe wearer suddenly bends the foot, the cushioning action of the part of the cushion material that protrudes from the rear end of the shoe protector will protect the foot. There is no need to apply too much pressure to the rear end edge of the foot protector, which has the advantage of avoiding injury to the foot.
