EFFECT: providing forced ventilation of shoes with the exception of discomfort when walking.

 

The technical field to which the invention relates.

The invention relates to the footwear industry and can be used in the manufacture of shoes, which generates a directed air flow on the plantar surface of the foot charge carrier when walking, thus improving the comfort of shoes.

The level of technology

The known device (sources: patents No. 2001592, 2118501, 2343809, 2343810) pneumatic, mechanical and combined types, designed for ventilation vnutrivennogo space, but have common disadvantages: complexity and bulkiness of the design, considerable weight, which is comparable with the total mass of shoes that weigh down the last.

Known ventilation devices - pneumatic pump (sources: patentâ„–2001592, 2118501, 2343809, 2343810), mounted in the insole, which represents a convex elastic polymer (rubber) sheath, hollow, having an opening for filling and venting. The upper surface of such pneumonias made in the form of a hemisphere or a similar form. On the upper surface of the shell pneumonias holes are located.

Pneumonias with elastic shell is located in the heel portion at the center of the heel, making it difficult to release the air, as if to touch and pressing the heel on the elastic membrane to overlap the existing holes. When Zab is in d air, when the heel does not force pressure on the elastic membrane of pneumonias, injects air into its cavity, it is also difficult, because the heel is in contact with the elastic membrane and the holes are blocked. A similar pattern occurs with elastic membrane located in the beam part, there is also hampered by filling the elastic sheath air and release it when stepped foot on the insole due to the overlap of the holes. Thus, the elastic filling forms air and venting is not effective.

A significant disadvantage of this design pneumonias with elastic shell is the fact that the holes are located on the upper surface of the insole and with the pressure on them to stop the material of the elastic shell is imposed on the material of the removable insoles, forming local additional second layer. This layer will be felt by eschikon, acting on the heel and the beam portion of the foot and causing a negative feeling with every step. In these structures the ventilating insole the surface of the elastic membranes of the pneumatic pump is not associated with the surfaces areas of the foot affecting them, which increases the pressure on these areas of the foot and causes negative feelings.

The invention

The invention is aimed at solving the following tasks:

- dost is just a simple means to provide ventilation vnutrivennogo space in the Shoe when worn;

- to improve the efficiency of the blower plantar portion of the foot in areas of intense sweating;

- eliminate the formation of the second layer - convexity on the surface of the removable insoles in the moment of greatest pressure, arising from the compression of the elastic shell pneumonias performing the functions of intake and exhaust;

- to provide the most favorable conditions for the interaction between contact surfaces of the elastic shaped shell of pneumonias and mating sites plantar surface of the foot-the heel and beams.

When solving the above problems, the proposed device combined ventilating insole will provide the following technical result:

- forced ventilation vnutrivennogo space will be made fairly simple design, the effectiveness of ventilation will be high;

stop charge carrier will not feel uncomfortable, because at the moment of maximum pressure foot will not rely on the convex surface formed by the compression of the elastic shell pneumonias.

The areas of the foot in contact with the elastic sheath pneumonias, will operate in the mode minimum contact pressure as an elastic shell of the pump is running in the associated sections of the foot) surface areas of the foot.

Venting is kombinirovannaya insole consists of supplementary and primary insoles, while on Deposit insole is fixed, for example, adhesive pneumonias in the form of an elastic membrane, which top is fitted removable insole, preformed in the areas of location of the pneumatic pump. In the main insole in connection with the elastic membrane of the pneumatic pump has a recess, in which when you stop elastic shell pneumonias last will to get into the groove, leaving the surface of the removable insole is smooth and without lumps, which could cause charge carrier shoes negative feelings when walking.

In the pneumatic pump on the surfaces of the shells in their parts, not covered by the footprint, there are a number of intake and discharge of air in the zone ventilation of the foot for enhanced evaporation secreted by the foot sweat and cooling. The location of the holes in these parts of the elastic membranes of the pneumatic pump provides free flow of air inside elastic shells, and of them squeezing their feet. The outer portion of the elastic membrane pneumonias placed in the heel part, overlapped by two-thirds by the imprint of the heel of the foot. The remaining inner portion of the elastic membrane pneumonias constituting one third part facing the inner side of the foot, does not overlap with the footprint, and there are openings for entry and exit of air, because the OS is real two quarters of the surface of an elastic shell are closed by the imprint of the plantar part of the foot. Coaxial holes in an elastic shell pneumonias are holes in removable insole. Tip-beam part of the combined ventilating insole is pneumonias with elastic shell, the last one-third is covered by the imprint of the beam portion of the foot. Openings for entry and exit of air in the elastic shell is made in the front two-thirds of its surface is not covered with the imprint. The location of the projection on the insole elastic shell pneumonias in the heel part is defined by lines transverse vertical sections:

the first extreme line is within 0,D - D, where D is the length of the foot;

the second last line in the range 0,D - 0,35D.

The location of the projection on the insole elastic shell pneumonias in the beam part is constructed on the upper contour of the imprint beam portion of the foot described curved line. Thus, the width of the elastic membrane pneumonias, component 0,D - 0,D, one third went under the imprint of the beam portion of the foot, and the remaining two-thirds of the width was out of print. Area, where will be located the elastic sheath pneumonias beam part that is between the standard sections 0,D-0,D. A somewhat smaller set of elastic shell pneumonias for beam portion under foot print compared to sunset elastic shell p is emoness for the heel part due to the fact, that beam of the foot when stepped on prop will move forward at 3-4 mm and will be further pressure on the elastic membrane, thereby increasing the release of air from the latter. This arrangement both elastic shells of the pneumatic pump and holes in them ensures free flow of air inside the elastic membrane and a free exit of air in ventilated area.

Elastic shell pneumonias in the contact zone with acting on it by sections of the foot is profiled in such a way that the contact area of the elastic membrane pneumonias had a response surface in the form of plots of the foot, acting on it, that by increasing the contact surface will reduce the pressure on the corresponding areas of the foot, as reportedly allowable compression of the foot shoes on the value of 10 g/cm2(source: Handbook of shoemaker, ed. LI, M.:1967, S. 41).

In the main insole component part of the proposed combined ventilating insole, on the upper surface, where the attached elastic shell, made deeper, allowing the moment of the maximum pressing on the elastic membrane pneumonias relevant parts of the foot to be placed in these depressions elastic shell and molded protrusions flush.

Due to this, on the surface of the proposed combined ventilating the bed shall not be any mounds, causing a negative feeling in charge carrier when walking.

Insole // 2401024

FIELD: personal use articles.

SUBSTANCE: single-layer insole is made of elastic material, has upper flat side facing foot, and lower profiled side facing the main insole, with which it creates a system of cavities and channels. Side of insole facing foot is flat. In heel part of insole there are through holes arranged parallel to central axis of heel. Layer facing the main insole is profiled, and in cross section it has longitudinal ledges of trapezoid shape with rounded angles (radius of rounding equals 2-4 mm). Between longitudinal ledges there are grooves arranged, which mirror anatomic shape of foot, with length from heel rounding to toe part. Height of longitudinal ledges in heel part and grooves arranged between them relative to thickness of insole makes 3:1, and they produce cavity that mirrors anatomic shape of heel. In waist and toe parts of insole, height of ledges and grooves relative to thickness of insole makes 2:1 and 4:1 accordingly. Ledges and grooves arranged between them are equidistant from surface of insole facing foot, and have widened outlets along perimetre of toe part, ending with cutouts. In toe part of insole there is an additional ledge with groove closed in waist area and opened in toe part, which adjoins group of longitudinal ledges and grooves at inner and outer sides accordingly. Upper layer of insole is duplicated with leather or other material to improve its hygienic properties.

EFFECT: improved comfort of inner shoe space due to forced directed motion of air from heel part of shoes into toe part, by reduction of volumes formed by grooves and ledges at lower side of insole, and the main insole, and increased speed of air motion as it travels in ledges of various volume along whole length of insole, with simultaneous creation of foot bed in heel and toe parts.
