Description

Ergonomic footbed insole.

Field of the Invention

The present invention relates to a template ergonomic footwear, and more particularly a template Ergonomic that adapts to the shape of the sole and does more comfortable the use of footwear when stepping on and walking, since It has specially padded areas depending on the parts of the foot that rest on them, and it is remarkably cushion of the footsteps. In addition, this template allows keep feet dry and healthy as it absorbs perspiration, It has deodorant, antibacterial, antifungal and, Optionally, it can also have antistatic properties.

Background of the invention

Most existing footwear and currently used have a template on the one that mounts the upper part of the shoe and that at the same time is fixed on the sole thereof, said template constituting the basis of Foot support of the footwear user. Some of the templates Their sole purpose is to cover the floor of the interior shoes simply to improve their appearance and therefore not they fulfill no anatomical or other function other than the esthetic.

Other templates are also known, for place in footwear or already incorporated, which are manufactured with materials that allow relative breathability, and being Padded provide some comfort to the user. Other types of existing templates have a relatively conformation anatomical with which, supposedly, it is intended to contribute to the correction of defects of the user's feet.

It can then be said that among the templates manufactured today some flat, more or less padded evenly across the entire support surface of the foot, and others called "anatomical" that supposedly adapt to the foot surface, presenting a simple plantar arch filling, without distinction between them, as if all the feet of the same size were equal and, in particular, as if all feet they had the same curvature of the plantar arch, which as we know It is totally wrong.

Consequently, in order to resolve the limitations and deficiencies of conventional templates such as those mentioned above, the template object of the present invention, which, in merit to its special constructive features, provides the user in general greater comfort and health at all times, both at Walk like when you are standing or sitting.

Brief Description of the Invention

The template in accordance with this invention brings together outstanding features such as ability to foot perspiration absorption, ergonomics, properties antibacterial and antifungal, thus avoiding the generation of odors unpleasant, it has a damping effect on the footsteps, between Other notable advantages. However, one of the most important features of this template is that it presents a specially shaped padding to completely fill the vacuum in the plantar arch of the feet. For this, the template has a joint defined by a cut in the approach, in such a way that that padding moves angularly with respect to an axis of turn, adapting perfectly to the inclined interior wall of the footwear, and making the arch of the foot rest entirely on said padding for the plantar arch.

Brief description of the drawings

For clarity and understanding of the purpose of the The present invention has been illustrated in several figures according to the preferred embodiment, all by way of example, in where:

Figure 1 is a representative scheme or footprint of the workforce areas where different parts support of the user's right foot.

Figure 2 is a top view of the template object of the present invention, corresponding to the right foot, the template for the left foot being exactly symmetrical to The illustrated one.

Figures 3a, 3b, 3c and 3d show cuts cross sections in the template areas respectively identified in Figure 2 with the letters A, B, C, D and E, where especially the articulation of the padded part is seen for the plantar arch of the foot.

Figure 4 shows schematically, according to a cut at the height of the instep of the foot, the insole areas where they support the heel and plantar arch of the user's foot such as planned.

Detailed description of the invention

In Figure 1 you can clearly see the main parts of foot support on the padded areas of Template. In fact, with the letter A the padded area is indicated of support of the fingers, with the letter B the padded area of support of the metatarsal, with the letter C the padded arch support area plant, and with the letter C the padded heel support area of the foot.

Surrounding the inner side edge of zone C with respect to the general perimeter of the workforce, in the E a defined articulation strip is formed of the template by a curved cut 1, which allows said zone C to be able to move angularly upwards around the axis of rotation structurally defined essentially between opposite ends of said cut 1. In this way, when placing the insole inside the shoe, the inclination of the side part of the footwear makes zone C of the template rotate and stay in a firm support position of the plantar arch of the user.

As easily understood, the angle of offset of the C zone of the template depends on the inclination of the side wall of the footwear, which allows your adaptation to each particular shoe, the perfect filling of the space corresponding to the plantar arch and, thus, a full User foot support.

Figure 2 shows the conformation of the padded areas A, B, C and D of the template, and especially the cut 1 that allows the turning of the zone C for the firm support of the plantar arch of the user's foot, indicating the lines corresponding to cross sections A-A, B-B, C-C and D-D that they are shown in detail in figures 3a, 3b, 3c and 3d. Such as it is observed, Figure 3c clearly shows the turn of zone C in three different positions, a first position without displacement angular, a second intermediate displacement position, and a third position where it is located with a greater angle of displacement.

In Figure 4 it is shown schematically in cut the outline of a shoe 2 with the user's foot 3, whose heel 4 supports in the padded area D of the insole, and whose arch planting 5 rests on the padded area C of the template. May the way in which said area C of the template can be appreciated it is positioned inside footwear 2 adapting perfectly so that the plantar arch 5 of the user finds a firm but Soft and comfortable support inside the footwear.

The structure of the template is made with latex foam molded by wave solders High frequency electromagnetic, giving the shape and thickness suitable for each of the padded areas. In this sense it fits highlight that the welding of the latex foam by waves High frequency electromagnetic has been achieved by adding a special electrically conductive additive, since otherwise not  it would be possible because pure latex is a material essentially dielectric. Said additive is an aspect product oleic commonly used in safety shoes. He aggregate of this type of additives necessary to make the welding by high frequency electromagnetic waves, being electrically conductive, also allow to contribute to this Antistatic properties template.

It should be noted that this template is used for latex foam with conductive additives, since other materials, such as PVC, even though they can be easily welded, they do not meet the appropriate properties to obtain a template such as the that is described In fact, both PVC and several others polymeric materials, they are breathable, do not absorb sweat, Nor are they biodegradable. Instead, latex foam has all these important properties, and with the addition of substances antibacterials and fungicides, deodorants and perfumes, among others possible, this template becomes a high product quality with remarkable and special features that are not found in existing conventional templates and marketed today.

For the manufacture of this template, we start of a latex foam plate with a uniform thickness of 7 or 8 mm, which is vulcanized on an elastic fabric that forms the cover upper 6 (see figures 3 to 3d). That thickness is suitable for padded areas B of the metatarsus, C of the plantar arch and D of the heel, but it is excessive for zone A of the fingers and for zone E of the packing, because with such thickness the foam would push excessively upward and would cause discomfort and / or injury from friction of the foot with the upper part of the shoe, especially on the toes. For this reason, also through welding by high frequency electromagnetic waves, it molds the foam in zones A and F reducing its thickness up to 2.5 or 3 mm, ensuring that in these areas the foam does not exert a force of thrust that may be excessive.

Vulcanized and molded foam on the cover upper 6 is then fixed with the same latex on a support bottom 7, which is flexible but stiffer than the cover upper 6. The molding of the padded areas is shaped only on the upper side of the template, leaving its flat bottom side for uniform support on the inner base of the shoe. Said lower support 7 can be made of cellulose, material textile, or other material, provided it is absorbent and breathable to be able to preserve the template properties as already expressed.

For the parts of the template that can get to be in direct contact with the user's foot, ok say top cover 6, such materials may be used such as leather, cotton, wool, polyester or fabrics synthetic The lower support 7 may be of various materials common possible, and that may present properties non-slip, to which they can also be added antifungal, antibacterial, anti-mite, perfume and softeners, and "aloe-vera", among others.

When this template is implemented it can be done with a standard format for general use as in a personalized way according to user requirements. The possibility of moving and changing the padding is also planned, in case this is more convenient for the purpose of adapt it to different problems of users' feet, their ways of walking, or supporting the feet, among other reasons.
