Description

The present invention relates to an internal footwear device with high or low upper products combining several specific components which allow the user to adjust the comfort of his feet himself in the same set.
The main causes of foot discomfort are: HYGIENIC - sweating
- odor - MECHANICAL - opposition to movements
- improper maintenance
- etc - VOLUME - lack of interior space or poorly distributed space
- temporary need for space (feet that "swell"
- etc - THERMAL - cold or hot outside
- humidity
etc
Several solutions have been sought to alleviate each cause of discomfort - HYGIENIC - regulation of perspiration by products
pharmaceutical
- aeration using poromeric materials
- ventilation by mechanical means using movement
a walk
- absorption of perspiration by tissues
spongy - MECHANICAL - adding internal or external soles in
flexible materials
- medical orthopedics on VOLUME measures - extension on extensible forms (shoemaker)
- use of flexible mounting materials - THERMAL - insulating products for cold, ventilated for hot
- chemical or electrical heating devices, but there is no simple and reliable device capable of solving these 4 sources of discomfort in a single footwear combination
The whole of this device including the present invention is represented
felt on the synoptic table FIG 1: the combined upper-aerated inner sole allows a greater efficiency of the device in footwear of tall uppers in particular. - -
According to an initial prior art search,
PATENT 2,597,728 - offers a stud system in the
outsole.They are not amo
neither visible nor distributed over the entire
plantar or aerated surface limiting
so their use
PATENTS 2,595,216 / 2,512,649 l 2,242,933 / 2,420 933 / 2,360,273
- offer treatments for problems
posed by sweating saturation
but according to fixed processes
PATENTS 2,547,705 / 2,255,693 - offers a ventilation system
by the sides of the footwear and
by the outsole which poses the
significant problem of sealing in the us
which no reliable process to date has
been found that does reduce the use of the
footwear product itself
PATENT 2,539,966 - offers an insole by adhesion
type "Velcr'o'ur the entire surface of the
first assembly for assembly purposes
factory fitted and not for the comfort of the
foot. This device does not give the possi
flexibility to insert ventilated elements. The
treatment (pharmaceutical) elements of
insole are assembled on the
above Velcro as traditionally
and are fixed there. It's very difficult, com
me he is known professionally, from enga-
manage an insole with a base
fully Velcro in the bottom of the
shoe; in the case of a boot
lined with additional fur or
shoe lined in jersey (80% in sport)
the "Velcro" hangs in the walls and
gives the placement of the insole
very random in daily use. This
device although using an assembly
self-adhesive is totally different on
these technical bases of the proposed device
attached
Each of the prior patents studied has the particularity of treating only one or two sources of discomfort according to traditionally recognized means. The aim sought by the present invention, included in an overall device which is the subject of other patents, is based on the general optic according to which the footwear product is a clothing product which must be treated in a concept composed of washable, changeable, interchangeable, adjustable elements and of practical use. According to this approach, the following goals have been considered - overall ventilation (lateral and under plantar) is necessary
without altering the initial sealing height of the article
footwear (15).

- the components most in contact with the feet must
be washable or disposable because the evaporation of the part
perspiration fluid without removing parts
solids (salts, stains, bacteria etc.) cannot be hygienic
that - in the same perspective as above pharma treatments
ceutiques must be possible without requiring a device
special but the same device of daily use, renewed
ble and removable - sub plantar support, very different from person to person
other, and also, of the right foot compared to the left foot
requires adjustment of removable, modular elements to
will by a professional or the user himself - an internal heating element is necessary but must not
not be the one absorbing perspiration which must be the vable or disposable - the heating element if it is electric (known modern process but little used in common products) must be lateral and of heat distributed by aeration and not sub-plantar, position locked in the area where the humidity concentration is highest.

- use of the same footwear for summer and winter by removing certain elements is desirable.

- dans le cas d'un produit chaussant ne permettant pafdun chausson amovible ,d'un composite tiae (10+11)qUi est considéré comme doublure et fixé sur la tige (4) de l'article chaussant.According to the general principles mentioned above, the aerated upper-sole combination for footwear of high or low uppers has been designed. It consists
- a combination of a plantar base and a stem
made up of at least one thickness of a textile (10) as
associated with a foam (l1). Textile is a type of mesh with
large openings allowing maximum ventilation and is also
non-absorbent. The foam is also very airy it is
composed of a crosslinked polyurethane particularly suitable for
retain perspiration by the angles of its exploded structure
, result of a physical or chemical explosion treatment
This cross-linked foam allows the retention of moisture without
absorption and restitution when walking to an element
lateral (A1) and sub-plantar (D3) absorbent.
also impregnated with PVC or polymerized neoprene, treated
giving it elasticity and firmness favoring the
return to extended position and interior air movement
- in the case of an article of footwear such as a rubber boot
an inner boot which consists of the upper (10 + 11)
fixed assembly on the plantar base (27). I1 is thus removable and washable

- in the case of a footwear product which does not allow removable footwear, a composite tiae (10 + 11) which is considered to be a lining and fixed on the upper (4) of the footwear item.

The sole of the foot is considered as a removable free insole. I7 can then be fixed by a velcro type system (25) a bottom sole "C" provided with the same complementary system (26) allowing the insertion between the plantar base (27) and the bottom sole "C" of complementary intermediate elements " D ".
