IMPROVED SOLE

SECTOR OF THE TECHNIQUE

The present invention relates to an improved sole that includes an energy absorbing device to improve the adaptability of the user's footprint, offering additional comfort to the footwear in which it is incorporated to reduce pressures, stiffness and impact on the user's walking .

The object of the invention is to provide a structure embedded in the sole to cushion and distribute the pressure and body weight of the user at each step, so that the structure embedded in the sole absorbs a large part of the impact generated when walking and allows reducing the High frequency content of the impact force generated during walking.

BACKGROUND OF THE INVENTION

In the state of the art, soles of very different types and materials are known and used, pursuing very different objectives. In this sense, soles are known that include structures and / or technical elements to favor the breathability of the user's foot, for example, in the form of cells or perforations that generate an exchange of gases between the inside and outside of the footwear.

Likewise, footwear with cushioning are commonly known in shoes intended for sports that in many cases correspond to a visible structure that alters the external shape of the footwear, specifically in the thickness and configuration of the cut, insole and sole.

However, the applicant of this utility model detects the need to implement embedded elements in the sole that favor the absorption of the impact of the tread and simultaneously cause the sole to flex so as to provide greater comfort to the user, without it being necessary to alter the external appearance of the footwear.

DESCRIPTION OF THE INVENTION

The sole configuration that is recommended in the present invention is intended to achieve a balanced distribution of plantar impacts and pressures.

In this way, the improved sole is integrated by an energy absorbing device located in the area of the sole coinciding with the heel of the user to absorb the impact generated when the user makes the tread.

The improved sole energy absorbing device is composed of at least:

- a central element disposed on the surface of the sole in contact with the ground, which is arranged so that it protrudes from the plane defined by the surface of the sole in contact with the ground,

- a plurality of lobularly arranged arms that emerge radially from the central element,

- a base on which the plurality of the arms rests, and

- concentric rings emerging from the base, being arranged in the opposite direction to the sole surface in contact with the ground,

In this way, it should be understood that the advanced position of the central element with respect to the plane defined by the surface of the sole in contact with the ground during the tread and the presence of the rest of the elements that make up the energy absorption device provide comfort to the user during the walk

Advantageously, the internal structure of the sole object of the present invention makes it possible to reduce the activation of the lumbar muscles and, therefore, contribute to the prevention of low back pain.

For all the above, the improved sole provides considerably lower angular speeds in the ankle than conventional soles. This allows the support of Foot is performed much more smoothly, resembling walking on a field of soft grass, considered by some experts as the reference of a healthy walk.

Likewise, the embedded structure of the energy absorbing device allows the sole to be flexed for molding during user travel.

For all the above, it should be noted that the improved sole of the invention allows to protect the user's joints, reduces the impact forces - increased the perception of comfort - and reduces plantar pressures and can avoid or delay foot pain.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures outlined, specifically in Figures 1 and 5, we observe that the improved sole object of the invention has an energy absorption device (1) located in the area of the sole coinciding with the user's heel.

Preferably, said energy absorption device (1) is integrated by the following elements:

- a central element (2) disposed on the surface of the sole in contact with the ground,

- a plurality of arms (3) arranged lobularly emerging radially from the central element (2),

- a base (4) on which the plurality of the arms (3) rests, and

- concentric rings (5) emerging from the base (4), being arranged in the opposite direction to the sole surface in contact with the ground,

As can be seen in Figures 1, 2 and 3, the central element (2) is arranged in the sole so that it protrudes from the plane defined by the surface of the sole in contact with the ground. That is, the location of the central element (2) is arranged as a highlight with respect to the tread surface, allowing it to be the one that first receives the impact on the tread.

The configuration of the energy absorption device (1), embedded in the sole, is such that it leaves visible the central element (2), the arms (3) and the base (4) on the surface of the sole in contact with the I usually. While concentric rings (5) are part of the internal structure of the energy absorbing device (1) that will not be visible to the user when the improved sole is mounted on a shoe. Notwithstanding the foregoing, the concentric rings (5) are of vital importance to favor the absorption of the energy received in the impact of the tread along the surface of the sole.

Preferably, the central element (2) is made up of four elongated body elements arranged radially to favor adequate energy dissipation received upon impact with the ground. On the other hand, in the preferred embodiment of the invention, the number of arms (3) that make up the energy absorption device (1) is preferably four, which rest on the base (4).

Likewise, in figure 2, it is observed that preferably both the arms (3) and the elongated body elements that make up the central element (2) have an inclination with respect to the surface of the sole to facilitate the transfer and dissipation of energy along these elements. Likewise, this configuration favors the balanced distribution of forces and weights to the sole.

Advantageously, the present invention has a central element (2) that protrudes with respect to the arms (3) of the sole. This leading position of the central element (2) is observable in Figure 4, where the leading distance of the central element (2) is defined with respect to the arms (3) which is at least 5 mm.

On the other hand, the concentric rings (5) that emerge from the base (4), and are arranged in the opposite direction to the sole surface in contact with the ground, provide an absorption of the energy flow, distributing it towards all The surface of the sole.

In Figure 5 we observe that the improved sole object of the present invention optionally presents savings (6) arranged in a manner coincident with the user's forefoot position. The purpose of the presence of savings (6) is to reduce the amount of material used in the manufacture of the sole and provide an additional feeling of comfort and flexion of the developed sole.
