Abstract

Protection device for the one of the big toe for sports activity designed for the prevention of football accidents, in particular to prevent micro traumatisms of the big toe, and also provide a post-traumatic stage, a function of protection of the new growth of the nail and the lower tissue of the big toe. # It is constituted from an ergonomically molded band made of polyester and cotton fabric, where a protective plate composed of a silicone gel element is adhered TPR ("Thermoplastic Rubber" or a thermoplastic rubber) and a carbon fiber sheet and a closure device consisting of two complementary Velcro elements {reg}. # The device is applied by wrapping it and fixing it on the finger, so that it is in contact with the nail and therefore cover the area to be protected.

Description

Protection device for the toe nail for sports activity.

Background of the invention

The present invention relates to a protective device for sports activity.

This invention is the first of its kind, since it is neither an immobilizer nor a support, it is a protective device designed specifically to prevent the painful injury of the micro-trauma of the big toe. Currently, in fact, there are no other products on the market that have been invented for this purpose.

Protecting the big toe of any trauma during soccer activity can be problematic, so it is about protecting the body part that suffers most during the practice of this sport. For this reason, it is necessary that such protection be as comfortable as possible, leaving the joint with maximum freedom of movement, not changing the important sensitivity of the foot and at the same time being able to protect the area most exposed to shocks due to the usual contacts with opponents.

In soccer practice microtrauma of the big toe almost always occurs either as a result of involuntary footsteps of the opponents with plastic or metal heels of the boots or by frontal crashes. There is no device or instrument that is used for this same purpose and avoiding this inconvenience with home-made methods is not simple, since a simple padding inside the shoe is not enough, as it would be undesirable, cumbersome, annoying and uncomfortable, while a rigid plate with inner or outer lining on the tip of the boot, is prohibited by regulation.

Description of the invention

The device can provide a practical and efficient solution thanks to its uniquely specifically designed shape and the choice of its materials, proven to be extremely comfortable and non-invasive during soccer practice, due to its small size. In fact, the device works by the principle of impact attenuation for the dispersion of the force in a larger area, thanks to a carbon fiber sheet that performs this function, whereby the impact is further mitigated by a TPR ("Thermoplastic Rubber" thermoplastic rubber) silicone gel bearing, which has the power to reject "approximately" 44% of the force received.

This device can also be used as post-traumatic protection by athletes who have the long regrowth of the nail in progress or who because of these types of accidents do not have any yet. In this way you can practice all kinds of sports activities, protecting the nail from a possible worse trauma during the growth phase, in which the nail is very thin and fragile and is likely to be lost once again, thus facilitating its healing .

The device consists of ergonomically molded bands of fabric, designed for the shape of the big toe of the right and left foot, assembled with a protective plate made of two different materials: a carbon fiber sheet of "approximately" -0.6 mm attached to a TPR silicone gel bearing ("Thermoplastic

Description of the drawings

This device can be made in two versions: one in version with internal wrap at the foot and another in version with external wrap at the foot.

The designs shown in figures 1 to 8 show the device in version with internal wrap to the foot on the big toe of the left foot. Each reference is equally valid for the device on the right foot that becomes a symmetric mirror on the left.

Description of a preferred embodiment

The device is made with different materials that make up the various components:

Silicone gel bearing TPR ("Thermoplastic Rubber" - thermoplastic rubber) printed in honeycomb micro-structure for adequate shock absorption (which

Carbon fiber sheet thickness of -0.6 mm "approximately", ergonomically curved (belonging to the top of the protective plate with respect to its application on the user's foot; element O and H of the drawings);

Cohesive adhesive of the components for high performance, used for fixing between substrates of different nature of a thickness of -0.25 mm "approximately" (necessary for fixing the components of the protection plate, for fixing the same to the ergonomically molded band and the Velcro® to the band). All components are then fixed further by the sewing machine (Figures 3, 5, 11 and 13);

Ergonomically molded band in polyester or polyester and cotton fabric for high resistance to wear and washing (designed for a natural return to the big toe, element A of the drawings);

Sailboat ® ultra-thin closure with a thickness of -2 mm "approximately" (fixed on the ergonomically molded band for comfortable closure and reopening).

It is mounted obliquely with respect to the fabric band to allow comfortable cone winding in use (element B of the drawing boards).

The device is applied simply by reclining the ergonomically molded band on the dorsal part of the foot so that the TPR ("Thermoplastic Rubber") gel is in contact with the toe nail and therefore The carbon fiber sheet covers the outside of the area to be protected.

After placing it correctly, the finger is wrapped by fixing it with the Velcro ® closure.

It can also be done in different sizes and measures to fit the different sizes of people's big toes.

The application of the protective device of the big toe nail is recommended before putting on sports or generic socks.
