Patent Report Description

SHOE sole and MECHANISMS PROVIDED FOR FOOTWEAR

EXCHANGES fluidic

Field of the Invention

[0001] The present invention relates to a sole of footwear and footwear comprising mechanisms that help reduce fluid concentrations in the footwear, the objects of the invention provide, among other advantages, footwear with better performances with respect to comfort and well being. The present invention lies in the fields of fashion and footwear industry.

Background of the Invention

[0002] The footwear market constantly seeks to develop technologies to expedite the production of footwear, as demand required in the market is very large. But the industry should also be directed to the preference of the final consumer, given that users are increasingly demanding.

[0003] With this in mind, the shoe industry is studying ways to provide your product greater utility and functionality at the same time, may please the consumer adapting their needs and preferences, aiming to make the most comfortable, durable shoes , adaptable and customizable and yet these features are achieved without compromising ease of use or handling of it.

[0004] In the search for prior art in scientific and patent literature, the following documents related to the matter were found.

[0005] The document US 2013/0232826 relates to a footwear understood to be a waterproof and breathable shoe, in which it comprises a structure with a total of six elements that are associated with each other, the elements are defined by a leather a lateral protection, a waterproof insole a sole, a stabilizer, and a sole that is associated with the function to remove fluids from the side of the footwear. The shoes made by US 2013/0232826 document is endowed with many elements to fulfill its function, hampering its assembly process and increasing the cost of manufacture. Still, in this arrangement, fluid passages in the sole, show discontinuity, enabling the fluid surplus accumulation in the soles. Nevertheless, the inner region of the sole, has no mechanisms to prevent contact between the fluid inside the sole and the foot of the user, making it inefficient for cases where the user footwear comes in contact with large accumulation of water.

[0006] US 2005/0217140 document refers to a footwear that aims to present ways to intensify in fluid communication with the environment, in which parts are defined by a sock, one sole and sole. In this configuration, the shoe comprises only a single path for the fluid, which is defined by straight ducts in the sole, the fluid flowing to the insole of the shoe sole. However, the fluid is theoretically dumped on the outermost surface of the sole, ie, on the surface of the sole in contact with the ground, jeopardizing the safety of the user that can tip over and cause a tumble due to lack of friction between the sole and the floor. Still, in this arrangement, the holes that allow "breathing" of the foot, being in direct contact with the ground, do not provide a way to decrease the amount of external fluids entering the shoe when, for example, a user steps on a or wet ground in a pool of water.

[0007] The document US 6,389,71 1 relates to a leather-permeable footwear comprising an insole provided with a hollow and with a sole with openings for fluid passages. Also, the insole consists of a protective membrane made of a material for waterproof which is associated with a protective layer (16). The document US 6,389,71 1 shows a shoe equipped with multiple elements that charges the price of the end product and increases assembly time. In addition, footwear does not propose solutions to release fluid from the bottom of the shoe in order to ensure user integrity by preventing that it does not lose its instability due to fluid flow in the shoe sole region. Furthermore, the solution proposed by US 6,389,71 1 does not present an alternative to reduce the amount of external fluids entering the footwear and even prevent these fluids from reaching the foot of the user, causing greater discomfort during use.

[0008] The document US 2006/0283043 relates to a footwear which intends to propose means to promote increased gaseous exchange between the interior of the shoe and the environment. The footwear is structured from an insole and outsole, wherein the sole comprises at its top a few randomly arranged projections and a central region that makes the fluid exchange with the environment, such central region is provided with small baffles which direct the air into and out of the footwear. The shoe has a single point of gas exchange which is located in the center of the sole, moreover, it has no way of fluid flow which reduces their efficiency with regard to gas exchange with the environment. Moreover, this solution does not present an alternative to reduce the amount of external fluids entering the footwear and even prevent these fluids from reaching the foot of the user, causing greater discomfort during use.

[0009] Thus, what is clear from the literature, no documents were found suggesting or anticipating the teachings of the present invention, so that the solution proposed here has novelty and inventive activity to the opposite state of the art.

[0010] More precisely, the solutions presented in the prior art does not fully solve the above problems, while meeting all the needs mentioned above in a single model of footwear, in addition the prior art shoes do not show efficiency in fluidic exchanges in developed shoes in order to allow for the safety and comfort of the end user. Summary of the Invention

[0011] Thus, the present invention aims to solve the listed problems in the art from the presentation of a new type of sole and footwear have mechanisms in order to improve the fluidic exchanges between footwear and means that surrounds it, and present a more economical footwear, safe and comfortable. Still, the solution proposed here provides a means to reduce the user discomfort with respect to exhaled by foot sweat, and provide a means to allow for better "breathing" of your foot while using the footwear.

[0012] In a first object the present invention provides a footwear sole having means for removing fluid and intensifying exchanges with the environment comprising:

The. at least one first portion (3);

B. at least one second portion (5) opposite the first portion (3); w. flow guides sole (1 1) located in the first part (3);

d. leaks sole (12);

and. linear passages (13) included in the second part (5); on what,

Detailed Description of the Invention

[0025] The descriptions that follow are presented by way of example and not limiting the scope of the invention and will more clearly understand the object of this patent application.

[0026] In a first object the present invention provides a shoe sole comprising:

The. at least one first portion (3);

B. at least one second portion (5) opposite the first portion (3); w. flow guides sole (1 1) located in the first part (3);

d. leaks sole (12);

and. linear passages (13) included in the second part (5); on what,

- the flow guides (1 1) bind an earlier point (21) at a later point (22) of the sole, wherein said flow guides (1 1) is uninterrupted;

- the sole leaks (12) are included in the flow guides (1 1), wherein said sole leaks (12) are fluid communication between the first part (3) and linear passages (13) of the sole.

[0027] In the embodiment shown in figure 1, showing said flow guides (1 1) outsole, wherein such tabs allow a better flow of the fluid because of having geometry similar cross section with rails, whose purpose is to collect the water that it flows, figure 1 also shows the sole of leaks (12) which is in holes where the purpose is to receive the drained fluid through the flow guides (1 1) of the sole (4) and releases it to the environment.

[0028] For explanatory purposes of the present invention, the term troughs, open ducts which have a defined section geometry being designed to drive from one point to another by sliding, liquid or granular substances. In one embodiment, the geometry of the base of the rails defining the flow guides (1 1) comprises forming a slightly bulging 'IT in the cross section of the gutters. However, the present invention is not limited to this geometry and may contain other various geometries, which also optimize the fluid flow.

[0029] It is understood by fluid substance that deforms continuously when subjected to shear forces and / or shear stress. Said fluid may comprise the physical form of the material, the liquid and gas phases. In the present invention, the fluid may be from an aqueous fluid, colorless, secreted by the sweat glands and distilled through the pores of the skin (perspiration), or even fluids from the external environment arising from rain or other water sources, or natural not to contact the user's shoes.

[0030] The said flow guides (1 1) are endowed with a previous point (21) furthest from the toe of the sole, and a rear point (22) furthest point of the user's heel, both points are connected through the main flow guide. Furthermore, said flow guides (1 1) have no interruptions exist between the previous point (21) and posterior point (22) guides.

[0031] In order to better detail of the invention, the term flow guides (1 1) without interruption as guides joined by any of the endpoints, ie, for any selected point of flow guides, the the same is connected to both the posterior point (22) and the previous point (21) so that there is no impediment barrier that prohibits fluid communication between any of the points forming the flow guides (1 1), as can be seen in figure 1 .

[0032] In the upper part of the sole (4) or the first part (3), as defined herein, which is in contact with the insole, have developed "accommodation pockets" of water so that in case of contact of user with a wet surface, water was prevented from passing directly to the sole assembly (4) - insole (2) and thus have contact with the foot of the user, causing discomfort. These pockets slow the entry of water which, in turn, is naturally eliminated so that the user leave the floor with a wet surface retains its dry foot, ensuring ventilation. These "accommodation pockets" are defined by the shape of the flow guide (1 1), since, due to their geometry and their uninterrupted track geometry in cross section accumulates a portion of the water that enters the shoe. Thus, the water entering the footwear only affects the user if the standing volume of water penetrating the shoe is larger than supported by said accommodation pocket.

[0033] The configuration shown by flow guides (1 1) in the sole ensures enough space for a suitable temporary accommodation of water, as explained in the section above. In one embodiment said flow guides (1 1) have continuous curvilinear geometry, not limited to the same.

[0034] For explanatory purposes of the present invention means a curvilinear geometry remains a geometry in which feathers predominate are curved in their formation, so that all the points that define the flow guides (1 1) are associated with a any curve. Such geometry is effective in the flow and expelling fluids soles, since such a configuration is the most preventing fluid can create barriers and obstacles to fluid flow.

[0035] For exemplification purposes, the flow guides (1 1) were prepared to comprise a channel design with four diagonal rods on the front, a diagonal rod and a section on 'it on the back, with all comprising curvilinear channel geometry and being fluidly interconnected.

[0036] In order to clarify the present invention, the term casting sole (12), as the absence of material forming an opening in the first part (3) of the sole and passes through to the recesses in the linear passages (13) of said sole. Furthermore, these recesses can be set to plan changes or difference in height between the second part (5) and the plane that defines the linear passages (13).

[0037] Although such linear passages (13) are arranged throughout the entire cross section of the forming shoe, in one embodiment straight diagonal channels in the bottom of the sole. Thus, the sole acquired increased resistance to breakage and tear during use, compared to footwear having a transverse orthogonal array. This embodiment also provides more advantages when outsole fabrication of thermoplastic material is of the conventional type, such as PVC injected.

[0038] As discussed above, the linear passages (13) forming a straight diagonal channels make the outsole acquires greater resistance to twisting and bending, preventing it undergoes shear, which could contribute to the emergence surface defects may take the material disruptions and / or tears, which would prevent the actual operation of the solution proposed here. At the same time, the provision of channels contributes diagonal greater adherence of the shoe with the ground.

[0039] However, the present invention is not limited to comprise linear passages (13) forming a straight diagonal channels, as shown in Figure 7, may comprise, for example, corrugated shape, zigzag, V, sinusoidal or any other geometry which allows boost resistance to bending or twisting of the shoe.

[0040] Further, as can be seen in Figure 7, the outsole has in the lower part of the shoe or the second part (5) non-slip elements defined by small protrusions (23) spaced across the surface area of ​​the second part (5) lower footwear, such prominences (23) help to increase the friction between the sole and the floor, preventing falls, landslides and / or user imbalance.

[0041] The sole also has planar region (24) at the bottom of the shoe that connects, in one embodiment with at least two linear passages (13) directed towards the center of the sole. As can be seen in Figure 7, the planar region (24) comprises separate plane of the second part (5) that comes into contact with the ground, where the planes of the planar region (24) and linear passages (13) are nearer the first part (3) of the second part (5). Also, in an embodiment, a point on the sole, the height of the plane of the planar region is coincident with the plane of linear passages (13). For purposes of exemplification of the foregoing, the planar region (24) has plane coincident with at least two linear passages (13) arranged in the central sole region of the footwear. This arrangement allows better drainage of the inside of the fluid to the outside of the shoe, and prevent secondary fluid from the user's sweat becomes concentrated in the footwear sole, allowing for possible slips, since the planar region (24) does not enter in direct contact with the ground during the normal walking a user.

[0042] Basically, the planar region (24) at the bottom of the sole is operable to increase the area for flow of fluid, allowing fluid to drain the sole leaks (12) may also be released by said planar region ( 24).

[0043] In one embodiment, the outsole comprises outsole leaks (12) having channels that allows fluid communication between the flow guides (1 1) and the side of the sole leaks (15 and 16), this configuration represented by Figures 3 and 4. This configuration also provides more efficient means to release fluids, as the sole fluid release allows both the side of the shoe as the bottom of the sole through the same linear passages (13).

[0044] Further, the sole comprises a convergent nozzle (19) as shown in Figure 5 which interconnects and / or allows fluid passage between said flow guides (1 1) and the sole leakage channels (20) . The convergent nozzle (19) functions as a fluid enhancer, since it due to its reduction of area increases the flow velocity, increasing the efficiency of the release of fluid from the environment and, moreover, creates a resistance for the entry of fluids from the external environment to the interior of the footwear.

[0045] The sole leaks (12), as detailed in figure 5, comprise an upper opening of the pouring of the sole, said convergent nozzle (19), which is formed by at least one inclined surface which connects the surface contact with the insole (2) with the pouring channel sole (20), wherein this arrangement allows increasing the tangential force at which the fluid is subject.

[0046] The channel leakage sole (20) as can be seen in Figure 5, is responsible for conducting the fluid stemmed convergent nozzle (19) to at least one of linear passages (13). In one embodiment, these channels the leak (20) are arranged orthogonally with respect to the linear passage (13) and have a width "a", while the linear passage (13) has a width "b", so the width "b" is greater than the width "a".

[0047] It is a second object of the present invention comprising a shoe leather (1), an insole (2) and a sole (4);

on what,

- the sole (4) consists of a first part (3) arranged to receive a sock (2);

- the leather (1) is associated with the sole (4);

- at least one insole (2) disposed above the first portion (3) of the sole (4).

[0048] The sole (4) proposed here footwear is as described above in the first object of the present invention, so that the elements associated with the sole (4), forming said footwear, this second object of the present invention intends to further enhance the fluidic exchanges between the shoe and the external environment, and allows a final product for sale to the consumer. The elements added to the outsole (4) are better defined hereinafter.

[0049] The leather (1) is joined to the sole (4) and comprises, in one embodiment, perforations arranged in all its internal and external area. Nevertheless, the leather has a side passage (7) of leather (1), more precisely located next to the plantar region of the user's foot, when it is using the footwear. For explanation purposes, the region of the foot can be defined by the intermediate region between the forefoot and the heel of the user.

[0050] The said lateral passage (7) follows the geometry of the shoe, and has rounded corners to avoid this concentrator medium voltage, decreasing the tear possibilities of the material that is when it is subjected to mechanical stresses such as twisting, flexural, tensile and / or compression.

[0051] Moreover, said passage on the side (7) allows increased ventilation inside the footwear to reduce or prevent problems such as excessive sweating in the soles.

[0052] The insole (2) is associable to the first part (3) of the sole (4) and has front leaks insole (9) and subsequent leaks insole (10), such leaks are positioned at points coinciding with contours defined by the flow guide (1 1). Therefore, the fluid tends to fall insole (2) by gravity flow to the tabs (1 1) and escoarem freely until said sole leaks (12).

[0053] Also, provision of the front leaks insole (9) and subsequent leaks insole (10) of the insole (2) is designed such that the sole leaks (12) and leaks in the insole would not become concentric, or is deliberately mismatched and with considerable distance between them, thus avoiding direct contact input or stemmed water from the external environment with the foot of the user, as well as sharp objects.

[0054] As seen in Figure 2, the insole (2) has front leaks insole (9) and subsequent leaks insole (10), wherein the insole is associable at the sole (4) the surface contact with the insole ( 2). The present leaks in the insole (2) are responsible for directing fluid flow to the sole guides (1 1).

[0055] The aforementioned leather (1), in one embodiment, an adjustment strip (6) consisting of three parts, a first part of the strap and a second part of the parallel strip each other, and a third linking the beginning of the first with the end portion of the second strip. Such a configuration allows better fit of the shoe on the user's foot addition to promoting greater comfort, simplicity in handling and well-being to the user. It is still important to note that the footwear of the present invention is not limited to use of straps for adjusting the leather (1) on the user's foot, may also be used laces, strings and even self adjustable uppers, etc.

[0056] Those skilled in the art will value the knowledge presented herein, and may play the invention presented in the embodiments and other embodiments which fall within the scope of the appended claims.
