Description

Non-slip element for use in insoles, heels or plantar supports placed inside  of footwear

The present invention relates to an element non-slip fitted with alveoli, cavities, grooves, channels or other forms of clefts practiced on its surface external, which make a windy function in a template, heel pad or plantar support placed inside the shoe, said templates, heels or plantar supports being perfected well of the shock absorber type to eliminate shocks and vibrations when walking (type comfort, comfort or relaxation) or medical-orthopedic type, incorporating all of them a special device that avoids the sliding effect that sometimes Accompany this type of products.

Technical field

This type of insoles, heels or supports plantar placed inside the footwear are manufactured usually in various materials, such as foams of various densities, silicones or polyurethanes and also in rigid materials such as plastics, metals and foams of different densities, and are commonly used by people who they stand a long time or perform long marches, as if they perform sports in which the feet are subjected to repeated impacts on the ground.

These templates, heels or supports plantar fulfill a main function, which is that of homogeneously distribute the pressure supported by the foot reducing the possible appearance of painful points and providing a massage continued on the sole of the foot.

In addition, this type of insoles, heels or plantar supports can incorporate a number of elements intended to improve the discharge action such as, for example, softer pads of the same material, both in the area of the heel as in the support of the metatarsal heads.

They can also incorporate others elements that fulfill a damping function to eliminate shocks and vibrations when walking (type comfort, comfort or relaxation) or also medical-orthopedic, such as a small elevation of the internal longitudinal arch or elements intended for provide a central heel discharge, in retrocapital support and the discharge of the metatarsal heads offering in this case a Perfect support for the entire sole.

However, this type of insoles, heels or plantar supports placed inside the shoe, they have a significant drawback for the comfort of user as it is that, for lack of an adequate fixation with respect to the shoes in which they are used, as the user walks, the insoles, heels or plantar supports tend to move, even when they have the appropriate dimensions and their Fit on the footwear is perfect. This displacement, in the case of an entire template, involves the formation of annoying wrinkles and, where appropriate, the displacement of the different elements orthopedics that may eventually incorporate such template, gives Place to inconvenient consequences that are easy to imagine. Of course, this displacement trend is most noticeable in the case of not complete insoles or heels.

Prior art

In the prior art various are already known templates, for example, the Spanish Utility Model no. 186,848 which refers to a template for footwear that incorporates in your base and in the area corresponding to the heel, a small piece magnetic, provided that, in the shoe and in an area coincidentally mount, for example by gluing, a foil metallic so that when placing said template in said shoe that is arranged in a fixed position that make possible an eventual displacement.

You can also indicate the Utility Model Spanish no. 1050585 which refers to an adherent template of silicone. In the case of this background, the adherent effect that provides the template is conditioned by its thickness, allowing the silicone material, being very thin the template, that the fibers of a sock or an average of a user are embedded in its surface, which is intended to avoid the user's foot offset with respect to the template. By therefore, it is the adherent effect derived from the constitution itself molecular material of the template and its small thickness the which allows said template not to move in relation to the neither the user's foot nor in relation to the footwear where it is being used However, this small template thickness, necessary to achieve the adherent effect of the same prevents offer the user the advantages of a thicker template and equipped, for example, with elements with orthopedic functions.

It is important to note that in none of the documents that have just been listed and whose contents are incorporated into this memory as a reference, the use of the suction cup effect exerted by an area of the template material, or by one or more insertions non-slip incorporated into it, on the inside of the footwear and generated by the user's own weight, to get the fixation of the template or plantar support with respect to footwear.

Therefore, the object of the present invention is provide a template, a heel pad or a plantar support of any other type that integrates one or more elements destined to prevent said template, heel pad or plantar support from moving incorrectly inside the shoe moving during your use.

Description of the preferred embodiments

Example one

Figure 1A shows a template of according to the invention, generally designated number 1, if it could also be a heel pad (figure 1B) or another plantar support

This type of template (1), usually manufactured in various flexible materials, such as foams of various densities, silicones or polyurethanes and also in rigid materials such as plastics, metals and foams of different densities and that could be provided, in a known way, of zones of different hardness or, even, of zones with functions of shock absorber type to eliminate shocks and vibrations when walking (comfort, comfort or relaxation type) or also of orthopedic medical type, also incorporates, according to the invention, a non-slip element (2) which may consist of a specific area of the template material itself (1) or an insert of a different material (see fig. 2), such as silicone gel, polyurethane, PVC, foam, leather and similar or a combination of several of them. The possibility of using chromatic codes to identify the different materials, with their specific properties, thus allowing a combination of the non-slip functions with other properties of the materials that constitute the windy element, such as hardness, flexibility,
etc.

Said non-slip element (2) has, in its lower side intended to come into contact with the part internal shoe (not shown), a plurality of alveoli, cavities, grooves, channels or other forms (3) of cleft practiced on its outer surface, which are best seen in the cross sections of figure 2 of the drawings in which said non-slip element (2) is represented as an insert of different material than the template.

Preferably, the non-slip element (2) will be provided on the back of the template (1) or support planting, that is, on the heel part and, as stated, you can be formed during manufacturing by template molding (1) or plantar support of the same material as this, or it can be manufactured separately from it (fig. 2) and then integrated, by for example, by gluing, in a cavity provided for that purpose in said template (1) or plantar support. The integration of an element Non-slip (2) of different material than the template can be carried out, also, during the manufacture thereof by insert molding.

While using a template (1) or support plant, according to the invention, and referring specifically to the heel element, since the functionality will be similar for any other non-slip element provided in the template (1) or plantar support, the user's weight acts directly on said non-slip element (2) compressing it against the part inside the footwear and making the alveoli, cavities, grooves, channels or other forms (3) of clefts practiced in your external surface, at times when the user's load on the template is relieved when walking, act as suction cups, exerting a suction against the inside of the shoe against which the lower face of said non-slip element is applied (2). In this way, it is possible to avoid the displacement of said insole (1) or plantar support with respect to footwear and / or foot of the user.

Of course, although in the described embodiment and illustrated, said non-slip element (2) has been shown with a circular configuration, you can also adopt any other form, such as oval, arched, polygonal, quadrangular or even lengthen in the direction longitudinal of the template, or in general in any other way that fits sensitively to the different support points of the plantar surface

Similarly, the shape of the section horizontal cross section of the alveoli, cavities, grooves, channels or  other forms of clefts (3) made on the underside of the non-slip element (2), can adopt any configuration other than what has been represented in the drawings, for example, circular, polygonal, honeycomb, ribbed profile, irregular. Whatever the configuration of said non-slip element (2) and of the cavities, grooves, channels or other forms (3) that it incorporates or that you want to add to the template (1) or plantar support, the suction effect that is achieved in its application with footwear, is the same.

Figure 2 shows two variants of this First embodiment. Thus, in the distinguished variant with the letter "A" shows an assumption in which the element non-slip (2) shaped or inserted in the template (fig. 1A), heel pad (fig. 1B) or plantar support (1) has its surface lower than the same level as the insole, heel or support plant (1), while in the variant distinguished with the letter "B" shows an assumption in which the element Non-slip (2) is inserted in the insole, heel pad or plantar support (1) and presents its lower surface protruding slightly on the plane defined by the base of the template, heel pad or plantar support (1).

Whatever variant A or B with which execute said non-slip element (2), the intended effect of suction that is achieved in its application with footwear, is the same, although they will be the cost and technical criteria of manufacturing, according to the constituent material of the element non-slip (2) or the weight of the customer for whom the template, heel or plantar support (1), which determine its Design and manufacturing.

The same technique of incorporating an area Non-slip (2) described, both in its variant A and B, is Applicable to any other anti-skid element desired add to the template, described below, without encouragement exhaustive, some other examples of realization.
