Description

SPORT SHOE WITH IMPROVED VENTILATION AND CUSHIONING.

  The present invention relates to footwear

sports res.

  In available sports shoes, the ventilation and shock absorption systems include transverse ventilation channels in the heel area of the intermediate layer (i.e. the wedge heel and the midsole), longitudinal slits open towards these transverse ventilation channels and vertical holes passing through the heel area of the double sole and of the intermediate layer

  to connect said transverse channels to the inter-

  ne of the shoe and, in some shoes of this type,

  the first may have channels in its underside

  be crossed by holes to transmit

  the air at the sole of the user's feet

  tions of the channels of the first do not correspond to those of the vertical holes passing through the double sole, the locations of the holes drilled in said first generally do not coincide with those of the channels of this first and, for these reasons among others, such shoes are not fully satisfactory in terms of ventilation and cushioning

shocks.

  To ensure flexible suspension of the foot,

  used elastic material in running shoes

  tick such as a copolymer of ethylene and vinyl acetate to form the middle layer over the generally hard outer sole In shoes of this type, the outer sole is generally a flattened element and the elastic layer is exposed to the surrounding space Unlike running shoes in which the load is mainly exerted from front to back, sports shoes on courts also undergo a significant lateral load due to the nature of the activities in which they are

  used, for example "basketball".

  In general, one aspect of the invention consists in proposing a sports shoe which, ensuring the ventilation of the foot of its user, comprises an air passage passing through an elastic intermediate layer (for example

  ple composed of a wedge heel and a midsole

  re) and has an enlarged air pocket, communicating with said air passage, also provided in the layer

  intermediate and designed to pump air through said passage

  ge in the internal space of the shoe when said

  middle layer is compressed between the foot and the ground.

  In preferred embodiments, a second ventilation hole is drilled in a double sole of the shoe and it is intended to communicate with the first ventilation hole, a second air channel is dug in the bottom of a first elastic of the shoe and it is open towards the second ventilation hole, and at least two third ventilation holes are made vertically in said first and intended to communicate with the second air channel and with the internal space of the shoe The intermediate layer comprises a midsole, a wedge heel and an external sole,

  the air pocket being hollowed out through the inter sole

  calaire and the compensated heel, the air passage groove being hollowed out through said heel and the first

  ventilation hole being drilled in said insole

  laire The second ventilation channels are arranged in a grid above the entire first and the first, second and third ventilation holes are located at the points of intersection of the grid In addition, these first, second and third holes vents have diameters between approximately 1.6 mm

and about 4.8 mm.

  In another aspect, the invention proposes a grid or network of second aeration channels distributed over the entire bottom of the first and of ventilation holes passing through this first at the points of intersection of the network of second aeration channels, so that air is distributed along these channels to all points under the user's foot and this foot is shock absorbed. The invention considerably increases the volume of air which reaches the interior of the shoe, by providing larger and larger ventilation holes and channels.

  more numerous and by arranging these air holes and channels

  tion according to an efficient network The invention proposes a system

  efficient air pumping device in the form of air pockets and grooves hollowed out in elastic components of the sole assembly, which considerably increases the amount of air entering the shoe.

  air circulation to all parts of the shoe

  re by extending the grooves to a point located

  beyond half the distance between the posterior and anterior ends of the shoe, and extending the network of channels located under the first to all

  the points underlying the user's foot The invention

  tion absorbs the user's foot against impact, thanks to the air trapped in the dug pockets

  inside the elastic components of the sole assembly.

  In another aspect, the invention provides a

  court sports shoe with an intermediate layer

  elastic diary in which horizontal transverse channels are provided, and an outer sole in

  rubber bonded to the external face of the intermediate layer

  diary that it surrounds by extending upward to

  reach the top of the shoe This form of reaction

  Lization ensures shock absorption while providing sufficient strength because the rubber of the outer sole runs along the perimeter and extends up to the top of the shoe, allowing this shoe to support the lateral load imposed by a sport on court without any seoaratiun occurring

between layers.

  In some preferred embodiments,

  the rubber outsole covers the inter-

  medial and she joined the top of the shoe all

  around the periphery of the latter.

  In other preferred embodiments, the rubber outsole extends upward, surrounding the outer face of the intermediate layer to

  join the top of the shoe, except on the inner side

  laughing o said intermediate layer remains stripped for

  clear the mouths of the transverse channels.

  In preferred embodiments also

  horizontal horizontal channels are provided

  in the middle layer from its interior region

  higher and transversely through this layer, and other holes in this intermediate layer and other parts of the shoe establish the communication between said channels and the internal space of the shoe to delimit a path traveled by the air up to to this space

  internal Because said transverse channels extend

  tooth only partly through the layer, there remains on the external face of this intermediate layer a solid zone having a thickness of at least approximately 13 mm in the transverse direction, which ensures solidity and stability during the load undergone by a court sports shoe In other preferred embodiments, the mid-layer is subdivided into a wedge heel and a midsole, and preferred arrangements of channels, grooves and dug holes

  in said midsole, in said heel

  dry and in other layers carry air from the exhaust

  channel chures, on the inside of the shoe,

  up to the internal space of the latter.

  In another aspect, the invention provides a

  sports shoe on courts with an inter-

  elastic medial without transverse channels, and a

  rubber outsole glued to this inter-

  medial which it surrounds by extending upward to join the top of the shoe, except on the inner side

  of the latter o said intermediate layer remains loose

  This release of the elastic intermediate layer on the inside of the shoe improves the aesthetic appearance.

  that of the latter and reduces its weight while continuously-

  ant to ensure the solidity necessary to withstand the

lateral load.

  Figures 15 and 16 to 18 are representations

  identical to those of Figures 9 and 11 to 13, respectively

  tively, representing a fourth embodiment

  applied to a sports shoe on courts without channels ,.

  but having an intermediate layer stripped on the side

inside of the shoe.

  FIG. 1 illustrates a sports shoe 10 of size 43, comprising a upper 12, an outer sole 14 and an elastic intermediate layer composed of a

  wedge 16 and a midsole 18.

  As shown in Figure 2, the wedge-heel 16 consists of a sponge of ethylene vinyl acetate (EVA) of decreasing section towards the front of the shoe, the rear end of the heel 16 having a thickness of about 22 mm (or "iron") Three grooves

  23 about 3 mm wide are provided longitudinal-

  across the entire depth of the heel 16, starting

  cant at a distance of about 25 mm from the end

  posterior tee of this heel 16 and continuing towards the anterior end of said heel 16 The central groove 23 is on a median axis 25 of the heel 16 and the other two grooves 23 are located at a distance of approximately 19 mm apart and other of this central groove The grooves 23 can be of variable width, provided that they are wide enough to allow the circulation of air, but not too wide to significantly weaken the structural cohesion of the heel 16, this is that is, this width should be between about 3 mm and about 6 mm. Two air pockets 24, of approximately 19 mm in diameter, are provided through the entire depth of the heel 16 and they

  are located on the median axis 25, their centers are found

  about 38 mm and about 63 mm respectively from the rear end of said heel 16 These air pockets 24 can be of variable diameter, provided that they are large enough to contain a reasonable volume of air, but not too wide so as not to weaken significantly the structural cohesion of the heel 16, that is to say that said diameter must be

  between approximately 6 mm and approximately 25 mm Five parallel channels

  the 26 are hollowed out transversely in the upper face

  heel 16 and they are about 25 mm apart The two channels 26 furthest to the rear cross the centers of the air pockets 24 These channels 26 have U-shaped sections and have depths of 7 mm, 7 mm, 6 mm, mm and 3 mm, respectively, starting with the channel

furthest back.

  As illustrated in Figure 3, the midsole

  calar 18 is a flattened element about 9.5 mm thick-

  sor, made of EVA sponge and decreasing thickness towards the front of the shoe This sole

  interlayer 18 is pierced with thirty-four air holes

  tion 27 approximately 3 mm in diameter At the front of the sole

  on 1 B, twenty-six of these ventilation holes 27 are placed

  at the intersections of a network of parallel lines longi-

  tudinal 28 and transverse parallel lines 30, as illustrated The adjacent transverse lines 30 are spaced by about 27 mm and the adjacent longitudinal lines 28 are by about 13 mm One of the longitudinal lines 28 is located on a median axis 32 midsole 18 Throughout the depth of the

  rear region of the midsole 18, are hollowed out

  two air pockets 34 approximately 19 mm in diameter, including

  the centers are located on the median axis 32, at distances

  these respective approximately 38 mm and approximately 63 mm from the rear end of said sole 18 As shown, eight ventilation holes 27 are arranged around

air pockets 34.

  As seen in Figure 4, a double sole 20 consists of a fiber plate of about 22 mm (or "iron") thick, pierced with thirty-eight air holes 36 of about 3 mm in diameter located at the intersections of a network of longitudinal parallel lines 38 and parallel transverse lines 40, as illustrated The adjacent transverse lines 40 are spaced about 27 mm apart

  and the adjacent longitudinal lines 38 are approximately

  ron 13 mm One of the longitudinal lines 38 is

  on a median axis 42 of the double sole 20.

  As illustrated in FIGS. 5 and 6, a first 22 consists of a molded rubber foam

  having a thickness of 10 mm at its posterior end

  lower and 4 mm at its anterior end A network of seven longitudinal parallel channels 44 and ten parallel transverse channels 46 is molded into the underside of the first 22 The longitudinal channels 44 have a width of approximately 3 mm and they are spaced about 13 mm One of these longitudinal channels 44 is on a median axis 48 of the first 22 The parallel transverse channels 46 Qnt a width of about 3 mm and they are spaced about 27 mm apart Fifty three holes ventilation 50 about 3 mm in diameter perforate

  the first 22 at the intersections of the canals, as shown

  felt The transverse canals 46 - and the longitudinal canals -

  44 have a depth varying from 2 mm at the front of the first 22 to 4 mm at the back of the latter

  27, 36 and 50 can be of varying diameters

  as long as they are large enough to allow

  be a free passage of air, but not too large to not significantly weaken the structural cohesion of the first 22, the double sole 20 and the midsole 18, that is to say that these diameters are located

  between about 1.6 mm and about 4.8 mm.

  S In the shoe in the finished state, illustrated on

  Figures 7 and 8, the sole assembly and the top 12 are assembled

  as follows: wedge 16 is insured

  jetti to the outer sole 14, which effectively blocks the

  holes at the bottom of this heel 16 The inter sole

  calaire 18 is subject to ta Ion 16 and to the sole

  external 14 the median axis 32 of this midsole

  -re being placed above and in alignment with the median axis 25 of the heel and the air pockets 34 of said midsole being placed immediately above the air pockets 24 of said heel In this way, the upper openings grooves 23 are closed, but four ventilation holes 27 located on the median axis 32 of the midsole communicate with the central groove 23 in the heel 16 The assembly formed by the outer sole, the

  heel and midsole is subject to the sole

  the double 20 and above the shoe 12, the median axis 42 of said double sole being placed above and in alignment with the median axis 32 of the midsole, while the network of longitudinal lines 38 and transverse lines 40 of said double sole is placed immediately above and in alignment with the network of longitudinal lines 28 and transverse lines 30 of

  the midsole In this way, the upper openings

  air pockets 34 are closed and the ventilation holes 36 of the double sole communicate with the ventilation holes 27 of the midsole, three of the ventilation holes 36 of said communicating double sole

  with three of the four ventilation holes 27 of said sole-

  the interlayer which opens into the central groove 23 The first 22 is placed or glued inside the shoe on the upper face of the double sole 20, the transverse 46 and longitudinal 44 channels being

  oriented above and in line with the lines trans-

  transverse 40 and longitudinal 38 of the network of said double sole The transverse channels 26 are provided

  in the heel 16 once the shoe has been assembled.

  When the shoe is in the assembled state, fresh air can freely penetrate into the channels 26, then into the grooves 23 and into the pockets 24 and 34 The air trapped in the grooves 23 and the pockets 24 and 34 can pass freely through the central groove 23, then circulate upwards via three of the ventilation holes 27 of the midsole and ventilation holes 36 of the double sole to reach the network of channels 44 and 46 of the first , then, from there, inside the shoe by traversing the ventilation holes 50 of said first The ventilation holes 36 and 27 of the double sole and of the midsole, respectively, which are located below and in the alignment of the ventilation holes 50 of the first, also serve as reservoirs for the air which circulates along the channels 44 and 46 The air

  entering the shoe refreshes and ventilates the foot.

  then it is evacuated through the permeable material which

  is made the top 12 of the shoe.

  Because heel 16, the midsole

  18 and the first 22 are made of elongated spongy material

  tick, the repeated rubbing of the user's foot against the ground causes compression of the air pockets 24 and 34,

  grooves 23, ventilation holes 27 of the midsole

  calaire and channels 44 and 46 of the first, requiring

  the latter to act as bellows to make penetration

  keep fresh air constantly and forcibly in the shoe

  which significantly improves cooling and ventilation while simultaneously absorbing shock to absorb the impact of the foot

the user against the ground.

  Figures 1 to 18 show sports shoes on courts, comprising a top 12, an outer sole 14, a wedge-heel 16 and a sole i 1 midsole 18 The midsole and the heel

  compensated together form an elastic intermediate layer

  than. In the embodiments of FIGS. 9 to 14, the wedge heel 16 (made of a copolymer of ethylene and vinyl acetate approximately 13 mm thick) has on its upper face five horizontal grooves 20 ′, the ends of which are spaced on the inside of said heel

  16 Two grooves 22 'extending longitudinally communicating

  quent with the grooves 20 ′ These grooves 20 ′ and 22 ′ are essentially similar to the grooves in the compensated heel described in support of FIGS. 1 to 8 In the heel 16,

  are also drilled three rows of five vertical holes

  wedges 23 'which pass through the entire thickness of said heel.

  The two outer rows are aligned with the intersections

  gorges 20 'and 22' The internal row crosses the

  20 'gorges halfway between 22' gorges.

  The midsole 18, which is a flattened EVA sponge element about 4 mm thick, has the same configuration of three rows of five holes 25 'as the heel 16, and these holes are aligned with those of said heel In addition, similar holes 26 'formed at the front and rear of the sole do not communicate with the grooves 20' and 22 'of the heel. At the front, there are four rows of these holes comprising, from the left right: a row of three holes located furthest forward, two middle rows of four holes and a row of three holes located furthest back This last row is vertically above the wedge area located

  most forward and said heel has a row corresponding

  of three holes 27 'However, the latter do not communicate with the grooves 20' and 22 'The holes 25' and 26 'of the midsole 18 and the holes 23' and 27 'of the heel can be drilled simultaneously after

  said heel and said midsole have been secured

  rises. A double senie ll 28 e which consists of a sheet of 2.5 mm (or "iron") thick fibers is located above the midsole 18 This double sole has a configuration of holes 29 identical to those sole

  tab 18, with which they are aligned.

  Above the double sole 28 'is a first elastic 30' which has a network of channels

  longitudinal and transverse 34 'in its underside.

  At the rear and in the center of the sole, three channels are oriented longitudinally. In the anterior region of this sole, - are added four additional channels, three inside and one outside There are eleven transverse channels Five rows each counting six holes 36 are aligned with the five transverse channels located furthest back Holes 38 ′ are aligned with the intersections between the longitudinal channels and the five transverse channels located furthest forward The row placed furthest forward has four holes , the next row has six, the next row has six, the next

  seven and the rearmost canal has six.

  There is a cross channel which has no holes.

  The dimensions of the channels and holes are essentially

  tiel similar to those of the channels and holes of the first described in the embodiment of the figures

1 to 8.

  The outer sole 14 (of rubber) is molded so as to extend upward to the top 12 of the shoe, to which it is secured.

  embodiment according to FIGS. 9 to 13, the rubber

  this outsole covers the midsole

  brace 18 and the heel 16 at all points of the perimeter of the sole assembly In the embodiments of FIGS. 14 to 18, this rubber of the outer sole covers the

  midsole 18 and heel 16 at all points, except

  tion made on the inner side where said midsole and said heel are released Six cavities are formed in

  the wedge heel of the outer sole.

  Conventionally, the top 12 of the

  shoe is made of a permeable material.

  The sports shoe on courts illustrated in FIGS. 15 to 18 is identical to that of FIGS. 9 to 13 with the difference that, just as for the shoe of FIG. 14, the rubber of the outer sole does not cover the layer. on the inner side, and that the many holes, grooves and channels are eliminated

outwards.

  The different soles and layers of the shoe are manufactured in the conventional manner. The grooves 20 ′ and 22 ′ are formed in the wedge heel before any assembly. As mentioned above, the

  holes in the heel and in the midsole

  can be drilled after these two items

have been united.

  In the assembled shoe represented in FIG. 14, fresh air can freely penetrate into the grooves 20 'and 22', then inside the shoe

  by traversing the holes in the heel, the insole

  air and double sole The air entering the shoe cools and aerates the foot, then it exits through

  the permeable material constituting the top 12 of the shoe-

  sure Under the action of the repeated friction of the foot of the

  liser against the ground, the elasticity of the heel, the sole

  the midsole and the first causes an air pumping effect which introduces fresh air by force into the

  shoe In the case of the assembled shoe represented

  shown in Figures 9 to 13, in which the outsole

  rubber completely covers the middle layer

  diaire, the ventilation air is also pumped in front of the foot, inside the grooves 20 'and 22' and outside

  of the latter, but, since this air must penetrate

  going in and out through the permeable material above

  the shoe, the air circulation is more bidi-

  only in the embodiment of Figure 14. It goes without saying that many modifications

  can be brought to the shoe described and represented

  without departing from the scope of the invention.
