ABSTRACT:
TECHNICAL FIELD OF THE INVENTION
This invention pertains to a boot, liner, insole combination, which may be advantageously used if the liner is attached permanently to a pants leg, in which the liner is restrained against inverting and pulling from the boot, when the foot of the wearer is withdrawn, and which may be advantageously worn by a wearer, such as a firefighter, who needs quickly to don the combination and to doff the combination.
BACKGROUND OF THE INVENTION
A protective garment for a firefighter is known, in which a boot liner is attached permanently to the legs of a pair of pants. Such a garment is disclosed in U.S. patent application Ser. No. 09/197,046, which was filed on Nov. 20, 1998, and the disclosure of which is incorporated herein by reference.
A practice is known wherein the boot liners are fitted into the boots before the firefighter dons the protective garment and the boots, so that the firefighter can don the pants, boot liners, and boots together, as a combination, whereby potentially valuable time can be saved.
However, a negative consequence of the known practice with the pants, boot liners, and boots known heretofore is that, when the firefighter removes his or her foot from the boot and from the liner, the liner tends to invert and to pull from the boot. Usually, it would be preferable for the liner not to invert so that the combination of the pants, boot liners, and boots can be dried together for reuse.
SUMMARY OF THE INVENTION
According to a first aspect of this invention, this invention provides an improved combination comprising a boot, a liner, and an insole. The liner may be permanently attached to one leg of a pair of pants. Similarly, such a boot, such a liner, and such an insole may be employed at each leg of the pair of pants.
The boot has a sole structure, which has a toe end and a heel end, and an upper structure, which is affixed to the sole structure. The boot is provided where the upper structure is affixed to the sole structure, at the heel end of the sole structure, with a recess opening toward the toe end of the sole structure.
The liner, which is fittable into the boot, has a sole portion, which overlies the sole structure of the boot when the liner is fitted into the boot, and an upper portion, which is affixed to the sole portion and which fits within the upper structure of the boot when the liner is fitted into the boot. Preferably, the liner is made from a filamentary material, such as nylon, Kevlar™, or Nomex™, whereby the liner is easy to don and to doff.
The insole, which is fittable into the boot, with the liner, has a toe portion and a heel portion and is attached to the sole portion of the liner, at least at the toe and heel portions of the insole. The insole is attached to the sole portion of the liner permanently, as by stitching, or detachably, as by hook-and-loop fastening means. The insole is adapted to fit between the sole portion of the liner and the sole structure of the boot when the liner and the insole are fitted into the boot.
The insole extends at the heel portion of the insole, beyond the sole portion of the liner, so as to provide a tongue, which is adapted to fit into the recess when the liner and the insole are fitted into the boot. When fitted into the boot, the liner and the insole are not held to the boot, except by the tongue fitting into the recess.
According to a second aspect of this invention, this invention provides a combination comprising such a liner and such an insole for wearing with such a boot. According to a third aspect of this invention, this invention provides such a boot for wearing with such a liner and with such an insole.
Hereinbefore and hereinafter, where it is mentioned that one element is affixed to another element, it is contemplated that the affixed elements may be unitarily made.
