Description

DESCRIPTION OF THE PATENT FOR INVENTION BY TITLE:

? SHOE WITH RETRACTABLE CLAWS?

Field of technique: in competition footwear.

The purpose of the finding? that of clawing the muddy ground, and then retracting them to clean them from the ground.

Pre-existing state of the art:

The cleats were stiff and clung to the mud, weighing down the shoe.

The technical problems encountered are the following:

The earth clung to the studs, weighing down the shoes and they slipped on the hardened ground.

Solution to the problem:

The stiff claw (1)? fixed to the rigid over-sole, while the elastic cleat? fixed to the underlying elastic under-sole; under the load, the claw comes out.

We now come to illustrate what? known:

? known that in soccer shoes it was necessary to vary the cleats according to the various qualities? of the soil.

It is known that mud clings to cleats in muddy terrain.

? I notice that cats have claws which, as they retract, clean themselves.

SPECIFIC DOCUMENTS ON PRE-EXISTING TECHNIQUE:

1- JP2004-167069 STRUCTURE FOR FOOTBALL SHOES

Under the sole there are 6 studs.

2- USD858947 FOOTBALL WEDGE

The heel ? wedge.

We now come to carry out the EXPOSURE OF THE INVENTION

With reference to table 1, The claws (1), steel ungulates, are fixed under the hard insole (2), while the elastic studs (3) in elastomer, are fixed to the underlying elastic sole (4); so that, in contact with the ground, the elastic studs give way, letting out the claws (1) that grab the ground, then retract from the studs to clear the sticky ground.

The position of the cleats under the sole? present at the point where the bones of the foot lower when walking, that is: first, under the heel, then under the sole.

UNIQUENESS OF THE INVENTION

consists in the fact that we are in the presence of a complete football boot.

BUILDABILITY:

in the shoe are placed n. 2 insoles: the upper hard to hold the claws, the lower soft one to hold the elastic studs.

BENEFITS:

1- the great specific pressure of the claws makes them penetrate any terrain.

2- the claws are cleaned by the elastic return of the studs.

3- first the claws come out, then the cleats support the weight of the athlete.

4- out of the ground, the claws disappear.

5- the elasticity? of the cleats returns a propulsive thrust to the player.

INVENTIVE ACTIVITY

1- the elasticity? of the studs returns a propulsive thrust to the player;

2- the claws in the shape of a nail, grab the ground;

3- the elastic studs accumulate energy, and then return it to the player when they leave the ground; then the athlete runs more? quickly;

4- when the shoe leaves the ground, the cleat returns to the outside, thus cleaning? the surface of the claws.

5- the clean nail does not drag with it? the sticky ground, which would weigh down the shoe.

6- in hard ground, the nail penetrates the ground, the cleat does not.

INDUSTRIAL ACTIVITY

Easy to build,? indispensable in soccer shoes, given the variability? of the state of the land.

The use can? be for all sports: rugby, football, baseball, running, long jump, pole vault, hiking.

Claims (1)

CLAIMS 1- Shoe with retractable claws, consisting of nail claws (1), fixed under the rigid insoles (2) and placed inside the elastic studs (3), fixed to the elastic insoles (4); characterized by there? that the claws (1), with steel claws, are fixed under the hard sole (2), while the elastic studs (3) in elastomer, are fixed to the underlying elastic sole (4); then, in contact with the ground, the elastic studs yield, letting out the claws (1) that grab the ground, then retract from the studs to clean themselves from the sticky ground. 2- Shoe as claimed in 1-, characterized by ci? what the position of the cleats under the sole? present at the point where the bones of the foot lower when walking, that is: first under the heel, then under the sole.
