Description

SHOE-COVERING PROTF.CTiON AfifiRMF.T.V

DESCRIPTION The present invention refers to a shoe-covering protection assembly of the kind comprising a pair of overshoe footwear, made of waterproof foldable material, to be worn for protecting shoes and clothes from rain, mud, dirt and the like.

Assemblies as the abovementioned illustrated one are known, they usually comprise bag-shaped footwear, which can be worn over shoes and are fastened to legs by means of strings and/or bands, or laces surrounding the leg at the heel, calf or knee thereof.

This kind of footwear, even ensuring the required waterproofness, hampers walking and runs the risk of being slipped off if worn for a prolonged period of time.

Furthermore, by forming folds under the sole, it does not guarantee a good ground sensibility and does not allow a good grip on the ground, in particular on surfaces made slippery by water. Another kind of protection assemblies provides the use of half-rigid overshoe footwear, equipped with its own sole and heel and which can be fastened to the leg by means of belts. This overshoe footwear, boouleg-like, offers a good protection but is not much practical due to its encumbrance hampering an easy transport, which is the most important requirement enabling protection also from sudden needs, such as unexpected downpours, change of tyres in the rain, skid-chain mounting, and so on.

The technical problem which is the basis of the present invention is to provide a protection assembly which allows obviating the abovementioned disadvantages with reference to prior art .

Such problem is overcome by a shoe-covering protection assembly as above illustrated, characterized in that it comprises close-fitting wearing means for adjusting the shape of said overshoe footwear in the insole, heel, rear vamp and instep regions thereof. 9 -

According to a preferred embodiment of the present invention, said close-fitting wearing means comprise at least a first lace with adjustable length, fastened to the overshoe footwear at the region of the rear vamp proximate to the heel, provided to surround the instep region and apt to generate a traction from the bottom upwards, substantially diagonally compared to the leg lower part .

The main advantage of the shoe-covering protection assembly according to the present invention lies in the fact that it can be easily worn, allowing at the same time to walk freely on ground in any condition with any kind of previously-worn shoe or boot, and to easily transport it when not used. The abovementioned assembly footwear adheres to the sole, to the heel, to the rear vamp of the shoe wearing it, allowing the user to benefit by all tactile sensations transmitted by the shoe without these being altered or deadened by folds or the like. Furthermore, when not used, the protection assembly of the invention can be folded back, occupying small room.

Additional features and advantages of the protection assembly according to the present invention will be better understood in the light of the here below detailed description of some preferred embodiments thereof, illustrated by way of example and not for limitative purposes with reference to the enclosed drawings, wherein : figure 1 shows a perspective view of a component of the shoe-covering protection assembly according to a first embodiment of the present invention; figure 2 shows a perspective view of a component of the shoe-covering protection assembly according to a second embodiment of the present invention; figure 3 shows a perspective view of a component of the shoe-covering protection assembly according to a - J

With reference to figure 1 in particular, a right overshoe footwear is illustrated, denoted 1 as a whole, belonging to a shoe-covering protection assembly which, even if it is not illustrated in its entirety, obviously comprises a left overshoe footwear similar and specular compared to the right one, plus accessories which will be described in detail hereinafter.

The footwear 1 is of the kind apt to be worn when it is necessary to protect shoes and clothing, in particular socks/sockings and trousers' legs, from the atmospheric factors, such as rain or snow, mud and dirt in general. For this purpose some parts corresponding as position to the equivalent parts of feet and/or shoes will be denoted by referring to these last parts.

The footwear 1 comprises a sole part 2, a vamp- covering part 3 and a first bootleg-like part 4. The sole part 2 is made of foldable material, waterproof and half-rigid; in particular it is made of a thin rubber plate or the like, for example para rubber which is transpirable, insole- shaped and sewn to the vamp-covering part by means of a waterproof seam.

The sole part 2 defines a rough contact surface capable of strong grip, to enable the footwear 1 having a good grip on slippery surfaces.

The sole part 2 can be divided into different regions, in particular the insole region 6 and the heel region 7.

The vamp-covering part 3 and the bootleg-like part 4 form a single whole constituted by parts sewn between them, made of waterproof material which is flexible and foldable . Said material can be, for example, a waterproof synthetic cloth whereas the seams too are waterproof by means of, for example, a plastic or silicone coating. Advantageously, the material of the vamp-covering parts 3 and bootleg-like parts 4 can be transpirable and waterproof, such as Gore-tex^® and the like.

The vamp-covering part 3 can be divided in different regions, in particular a tip region 8, an instep region 9, a rear vamp region 10, an annular ankle region 11.

To prolong its life, the footwear 1 includes strengthened areas, by means of, for example, thicker layers or of several overlapped layers at the tip region 8 and the heel region 7. The bootleg-like region 4 too can be divided into a leg front region 12 and a leg rear region 13.

A heel region 14 can be then seen which, considering that the footwear 1 is employed to cover a shoe, partially extends both in the heel region 7 and the rear vamp 10.

The footwear 1 shows a substantially smooth inner surface, to improve wearing comfort, and an outer surface, high visible by night, which is fluorescent and/or partially reflecting with bright colours such as yellow, orange and the like.
