Description

Sole for shoes with locking mechanism with respect to the outside ventilation or liquid inlet external

Object of the invention

The present invention relates to a sole for footwear with locking mechanism with respect to the entrance of external or external liquid ventilation, which provides essential novelty characteristics and notable advantages over means known and used for the same purposes in the state Current technique.

More particularly, the invention develops a sole for footwear that incorporates a plant in whose shell union to the floor have been articulated means that in collaboration with the Complementary made on the floor itself, constitute a mechanism that not only acts as a ventilation regulator integral of the user's foot, but also such when means are pressed under the weight of the user applied to the walk, provide an effective closure that cuts off the access of inlet both for ventilation from outside and in avoidance of external liquids, for example water or others liquids sitting on the ground, can penetrate the space inside the sole and wet the user's foot.

The scope of the invention is obviously, within the industrial sector dedicated to the design and manufacture of soles for footwear, in particular soles for footwear of the type they supply integral ventilation to your interior space.

Background and summary of the invention

The effect is generally known to everyone beneficial that provides good ventilation at the foot of a user of any piece of footwear. This effect not only results in in eliminating odors that may be caused by accumulation of certain bacteria; it helps maintain a proper foot hygiene for optimal maintenance sanitary conditions, this one is so important for hygiene general body

As is known, they currently exist in the state of the technique a multiplicity of soles for footwear with which aims to keep the foot of the different users in perfect conditions of use and hygiene, for which purpose, the various developments referred to incorporate some means intended to allow air to enter inside the sole, and pump it successively outwards, as the Bearer of these pieces of footwear.

A sole is also known for footwear, object of registration and manufacturing by the same applicant of the present Utility Model, in which the inclusion of a valve located at the rear of the sole, provides a air inlet that is properly distributed below the sole, this valve being capable of closing itself same when the user, when walking, rests the heel on the area in which it is located, and whose elastic recovery of material with which it is manufactured, makes it open again when the pressure on it ceases.

Although many of the sole embodiments for existing footwear in the state of the art provide aeration results that could be considered as satisfactory, it is also true that a good part of those realizations suffer from a very important defect, derived from the fact that the same entries through which the air for the soda of the foot, also constitute entrances for the external liquids, for example water that may exist in the soil, with the consequent unpleasant result for the user of that the foot gets wet, with the inconvenience that this entails.

Taking into account these inconveniences of existing soles, the present invention has been proposed as main objective is to develop a sole for footwear substantially improved with respect to the known ones, by means of the that not only the healthy and desired integral ventilation is provided of the foot in all its extension, but at the same time it prevents that they can sneak liquids inside and get to wet the user's foot. This goal has been fully achieved through the sole that goes to be described in the following, whose characteristics main are collected in the characterizing part of the attached claim 1.

In essence, the invention provides a sole for footwear in which a ventilation mechanism has been incorporated and airtight closure to achieve both effects announced previously, for which a sole consisting of one floor and one floor adjustable in the interior floor space delimited by a perimeter wall obtained as elevation emerging from the edge of the floor and integral with it. Plant, built in a lightweight material, and endowed as usual of small through holes at least in a large portion of the it incorporates an intermediate piece on its lower face in centered position, extended to most of the extension surface of this lower face and embedded in the plant, whose intermediate piece shows the formation of a multiplicity of prismatic cross section formations preferably ellipsoidal, which at the start have staggered portions, to ring or necklace mode of larger dimensions, being these formations generally organized in longitudinal rows, and leaving spaces between formations longitudinally or transversely adjacent in which stretch marks or small grooves have formed which follow both longitudinal and transverse directions, and that connect with the through holes of the plant. In the intersections of the mentioned stretch marks, formations appear very low circular, intended to rest on the face internal floor and keep the sole slightly raised relative to the plane of the latter.

For its part, the floor shows a rear cavity that crosses the back wall, and that is destined to house a Valve of the type discussed above. In the zone central, shows a strip in relief whose dimensions correspond approximately to the dimensions of the piece intermediate described above, in a position facing this last when both floor and floor pieces are coupled between yes, and also presenting this elevated interior strip the formation of a multiplicity of through cavities, arranged in positions  correspondingly equivalent to prismatic formations protrusions of the intermediate piece, of equal staggered configuration that the latter, which they receive and shelter when the plant is Attach to the floor. The pressure exerted by the user's weight causes the elastic deformation of the annular portion of each of the prismatic formations, with a perfect tight fit to the walls of the respective cavity, and with the consequent action of pumping for the expulsion of any liquid was able to penetrate the cavity, like the air flow admitted with the opposite movement, being favored this action of expulsion of the air by the mentioned cylindrical formations of low height that separate the floor from the floor.

As will be understood, with a sole designed from the way that has been exposed in the brief description above, it adequately guarantees both integral foot ventilation and the formation of a suitable barrier to the entry of liquids towards the interior space of the floor.

Description of a preferred embodiment

As indicated above, the detailed description of the preferred embodiment of the The present invention will be carried out in what follows with the help of the attached drawings, through which the same numerical references to designate equal parts or similar. Thus, attending first to Figure 1, you can appreciate a perspective view of the sole floor, designated in general with numerical reference 1, and consisting of one piece obtained by a simple molding operation, operations of bimolding, or any other technique commonly used For this type of items. As represented, floor 1 it has a perimeter wall 2, of reduced thickness, integral with the rest of the piece, and emerging to an irregular height default In the interior space a central portion is distinguished 3 in relief, that is to say high relative to the surface plane of the interior face of the floor, which affects most of the extension surface of the latter, and in which a multiplicity is shown of through perforations, determinants of cavities that in plant preferably adopt an elliptical shape, and that at a height By default they form a step 5 around a central hole 6. The cavities are distributed in rows according to both directions longitudinal and transverse, successively separated from each other adjacent by predetermined distances. There are other holes Blind 7 in interspersed positions between elliptical cavities mentioned, the holes 7 of the diameter plant area being appreciably larger than the holes in the floor area of the floor.

Figure 2 shows a sectional view taken along line II-II of Figure 1, where they can better appreciate the different configurations adopted by both the central strip 2 as per the cavities 4 with their respective stepping 5.

Figure 3 illustrates a schematic view, in perspective, of a piece of plant of the type of which they are usually used for the formation of soles, conceived and specifically designed for use in the proposed sole for the invention The position in which the plant part appears it is inverted with respect to its habitual use, so that the face seen in the drawing will be intended to serve as a mask in your coupling to the floor of Figure 1.

As can be seen, the plant part 8 illustrated in Figure 3 it has logically a configuration that allows a coupling in the space delimited by the perimeter wall 2 of the floor 1, presenting at the same time a central piece 9 embedded in the anterior, in a centered position with respect to the first, and of a dimensions approximately equivalent to those that delimit the area 3 raised from the interior of the floor 1.

Likewise, in a complementary way with the aforementioned raised area, the central part 9 has a multiplicity of 10 prismatic formations that emerge with a configuration prismatic elliptical cross section similar to that shown through the cavities 4 of the floor 1, these formations being constituted in height by two portions 10a, 10b, of which one first portion 10a is larger than the second portion 10b, forming a kind of annular widening or initial collar with respect to the last cited. The center piece 9 is delimited by a perimeter wall 11 that rises substantially above the surface plane of the piece, existing also stretch marks or small grooves 12 extending longitudinally and transversely interspersed between the mentioned prismatic formations 10, appreciating cylindrical elevations 13 that emerge from the intersections of the mentioned grooves 13, and which occupy positions approximately corresponding to that occupied by 7 blind holes in floor 1. In addition, there are also small through holes 14 in intermediate positions of the transverse grooves 12 of the area of the piece facing the sole of the user's foot.

Figure 4 shows a section taken by the line IV-IV of Figure 3, in which they can appreciate the details of the 10 prismatic high formations emerging from the surface of centerpiece 9 embedded in the floor 8 of the sole, as well as the formation of wall 11 up to a height above the surface plane of the mentioned piece central 9.

Finally, as an additional feature to the configuration described, the formation of a additional opening 15 at the rear of floor 1, in communication with an internal cavity 16, sized and adapted to receive and house a conventional valve, as an element of air passage for the refreshment of the user's foot.

As will be understood, the configuration of the different elements that make up the 8th floor, it is absolutely complementary to those that define floor 1, given that the latter It must receive and accommodate the first in the condition of use. The 10 ellipsoidal prismatic formations are designed for your accommodation in cavities 4 while formations cylindrical 13 of low height determine a separation between the respective faces facing the floor and floor pieces that ensures the passage of air throughout the interior space of the floor, and so that the air is renewed and provides the foot soda of the user.

Figure 5 shows the position of coupling between the pieces of floor 8 and floor 1, appearing now the plant represented in the correct position with respect to the floor 1, that is, inverted in relation to the representation of the Figure 3. Cavities 4 of elliptical section will receive the 10 high formations of the plant, the steps being respective 5 and 10a those that determine the amount of introduction of the latter in the former, and the portion 10b being housed in the inside of the hole 6. With the weight, the ring portion 10a expands the walls of the cavity, thereby determining a mechanism that by virtue of the friction exerted on the latter, a tight junction is provided along with a pumping effect outward that expels any liquid you could try enter through the holes in the cavities, thus maintaining Interior floor space isolated. On the other hand, as has said, the separation between the floor and the floor determined by the height of the cylindrical formations 13, prevents a total union between the facing faces of both pieces, keeping a space that helps out the flow of air generated by the foot of the user when walking, being the step of this flow provided by the valve (not shown) coupled in hole 15 of the rear wall of the floor and in fluid communication with the channels of distribution through the cavity 15 in which said housing is housed valve. The small channels 12 help the aforementioned distribution, while communicating with holes 14 that they cross part 8 precisely in the support area of the plant of the user's foot which is where more ventilation is required.

For its part, the wall 11 that surrounds the piece central 9, aids in the tightness of the assembly during the use of the sole, by supporting intimately with the 1st floor completely surrounding the area where the cavities are formed 4. This wall also fulfills the function of providing an effect of resistance to absorb the weight exerted on the sole and distribute it throughout the plant, helping to avoid malformation of the ellipses and rings that make up the formations 10 and the cavities 4.

In the above, part 9 has been described as embedded in plant 8. As will be understood, the provision of a elevated area as described may be provided based on two pieces separated and joined together by an operation of bimoldeo, pasted or any other, or the mentioned area in relief 9 can be formed in the plant itself and be integral with the same.

On the other hand, it will be understood that the piece of 8th floor will be built with any light and soft material of the usual ones for this type of pieces, in order to provide to the user the maximum comfort during the use of the sole in the cooler and rainier seasons of the year.

It is not considered necessary to make the content of this description for a subject matter expert can understand its scope and the advantages derived from the invention, as well as develop and implement the object of the same.

However, it should be understood that the invention has been described according to a preferred embodiment thereof, so which may be subject to change without implying any alteration of the basis of said invention, being able to affect such modifications to the shape, size and / or Manufacturing materials.
