Abstract

The elastic heel of any kind of shoe , especially e. g. orthopaedic shoe or plaster cast, consists of a component allowing parallel approaching and retreating motion of the sole-part and the part underneath the inner part of the shoe heel, where between them an elastic element is placed and the heel is protected with a flexible lining.

Description

Področje izumaFIELD OF THE INVENTION

Predmet izuma je elastična peta obuvala različnih vrst, tudi posebnih, npr. ortopedskih ali celo mavčnih oblog.The object of the invention is an elastic heel of various types of shoes, including special ones, e.g. orthopedic or even plaster coatings.

Tehnični problemA technical problem

Tehnični problem, ki ga rešuje izum je, kako zasnovati tako elastično peto obuvala, ki bo namestljiva na poljubno obuvalo, pri čemer ne bo spreminjala njegovega zunanjega izgleda in bo zagotavljala čvrsto stopanje.The technical problem solved by the invention is how to design such an elastic heel of the shoe that will be adjustable to any shoe, without altering its appearance and providing firm footing.

Znano stanje tehnikeThe prior art

Znane elastične pete so izvedene v celem iz elastičnega materiala, npr. gume ali penjene gume. V posebni izvedbi je peta večslojna. Za en vmesni sloj je uporabljen elastičen material, spodnji pohodni sloj je izveden iz mehansko odpornega in profiliranega gumenega materiala, notranji sloj pa je tak, da se ga lahko kvalitetno prilepi na vrhnji del obuala.Known elastic heels are made entirely of elastic material, e.g. tires or foams. In a special design, the heel is multi-layered. The elastic material is used for one intermediate layer, the lower hiking layer is made of mechanically resistant and profiled rubber material, and the inner layer is such that it can be properly adhered to the top of the shoe.

Nadalje je znana peta pri športnih obuvalih, ki vsebuje prečno potekajoče paličaste vložke iz elastičnega materiala, medtem ko je sicer podplat skupaj s petnim delom izveden iz tršega materiala. Te elastične vložke z različno elastičnostjo je mogoče tudi menjati glede na različne potrebe.Further known is the heel for sports shoes, which contains transverse rods of elastic material, while the sole together with the heel is made of a harder material. These elastic inserts with different elasticity can also be changed according to different needs.

25739/D17-IV-97.Vr.25739 / D17-IV-97.

Pomanjkljivost obeh rešitev je v tem, da taka peta ni stabilna že pri sorazmerno neznatni izvenosni obremenitvi. Hoja s takim obuvalom zahteva večjo pozornost, zlasti pri hoji po razgibanem terenu. Pri hoji ali celo teku po poševni podlagi nastopajo strižne sile, ki močno elastično deformirajo tak podplat, s tem pa povzročijo nelagoden občutek in zmanjšajo ravnotežje uporabnika. Tako nepredvidljivo preoblikovanje obuvala pomeni večji napor za stopalna in gleženjska tkiva, pa tudi nevarnost oziroma večjo možnost za izvin gležnja.The disadvantage of both solutions is that such a heel is not stable at a relatively low extrinsic load. Walking with such a shoe requires more attention, especially when walking on rough terrain. When walking or even running on a sloping surface, shear forces occur, which strongly deform the sole of the sole, causing an uneasy feeling and reducing the balance of the wearer. Such an unpredictable transformation of the shoe means more effort for the foot and ankle tissues, as well as a danger or a greater chance of ankle sprain.

Navedeni rešitvi nista primerni za različne prebolevnike npr. z zlomljeno nogo, kolkom, hrbtenico. Te osebe so zaradi bolečin in atrofije mišic dokaj nestabilni pri hoji, nojno pa potrebujejo pa obuvala, ki bi blažila udarce na skelet pri hoji, zlasti po trdi podlagi.These solutions are not suitable for different patients eg. with a broken leg, hip, spine. These people are quite unstable when walking because of muscle pain and atrophy, but they need the shoes to soften the impact on the skeleton while walking, especially on a hard surface.

Rešitev tehničnega problemaThe solution to a technical problem

Rešitev opisanega tehničnega problema po izumu je v tem, da vzmetni element v peti omogoča elastični skrček pete samo v smeri pravokotno na podlago, oziroma v osi osebe, medtem ko preprečuje poševni nagib pete pri nesimtrični obremenitvi. Razen tega elastični vložek po izumu ne upliva bistveno na zunanji izgled obuvala, s čimer omogoča njegovo poljubno oblikovanje.The solution of the described technical problem according to the invention is that the spring element in the heel allows elastic shrinkage of the heel only in the direction perpendicular to the base, or in the axis of the person, while preventing the oblique tilt of the heel in asymmetrical loading. In addition, the elastic insert according to the invention does not significantly affect the outer appearance of the shoe, thus allowing it to be arbitrarily shaped.

Bistvene značilnosti izuma bodo pojasnjene v nadaljevanju na osnovi opisa dveh izvedbenih primerov, ki sta prikazana na priloženi risbi, na kateri kaže sl. 1 vzdolžni prerez čevlja z elastično peto po prvem izvedbenem primeru izuma, sl. 2 elastično peto po prvem izvedbenem primeru v perspektivnem pogledu, sl. 3 elastično peto po drugem izvedbenem primeru v prečnem prerezu.The essential features of the invention will be explained below on the basis of the description of two embodiments shown in the accompanying drawing, in which FIG. 1 shows a longitudinal section of a shoe with an elastic heel according to the first embodiment of the invention; 2 is an elastic heel according to the first embodiment in perspective view; FIG. 3 is an elastic heel according to another embodiment in cross section.

Prvi izvedbeni primerThe first embodiment

Elastična peta po prvem izvedbenem primeru je izvedena kot plošča 1, oblikovna kot črka V. En prosti krak 2 poteka vzporedno in tik pod notranjim slojem 3 poljubnega obuvala A, na katerem leži stopalo. Drugi, spodnji krak 4 pa poteka vzporedno in tik nad podplatom 5, s katerih hodimo po podlagi. Vzmetnost materiala, iz katerega jeThe elastic heel according to the first embodiment is made of plate 1, shaped like a letter V. One free leg 2 runs parallel and just below the inner layer 3 of any shoe A on which the foot rests. The second, lower arm 4 extends in parallel and just above the sole 5, which we walk on from the base. The springiness of the material it is made of

2S739/D17-lV-97.Vr.2S739 / D17-lV-97.

izvedena plošča 1, omogoča razpiranje in stiskanje obeh njenih krakov 2 in 4 ob različni obremenitvi. Ker sta kraka 2 in 4 ploščata, zagotavljata vzporedno medsebojno primikanje ali odmikanje tudi pri izvenosni obremenitvi. S tem zavarujemo stopalo in gleženj pred morebitnim izpahom ali izvinom zaradi sprevračanja obuvala.realized plate 1, allows to open and compress both its legs 2 and 4 at different loads. Because the arms 2 and 4 are flat, they provide parallel movement or offset even in extra-axial loading. This protects the foot and ankle from any bumps or excuses for turning the shoe.

Med krakoma 2 in 4 je lahko vstavljen še dodaten elastični element 6 poljubne znane konstrukcije, ki spremeni elastično karakteristiko elastične pete. Celotna plošča 1 je zaprta v gibki oblogi 7 poljubne oblike, ki varuje notrajost pete pred umazanijo.An additional elastic element 6 of any known construction may be inserted between the legs 2 and 4, which alters the elastic characteristic of the elastic heel. The entire panel 1 is enclosed in a flexible lining 7 of any shape that protects the inside of the heel from dirt.

Drugi izvedbeni primerAnother embodiment

Slika 3 prikazuje drugi izvedbeni primer elastične pete, ki je primerna za poljubno obuvalo. Peta je izvedena iz podplata 20 in notranje ploščice 21, s katero je peta nameščena na petni notranji del obuvala, ki ni prikazan na sliki, in teleskopskega oboda 22. V notranjosti je med podplatom 20 in ploščico 21 nemeščen elastini element 23, prednostno vzmet, ki elastično prestreza obremenitve. Obod 22 pa preprečuje izvenosno upogibanje pete z istim namenom, kot je bil že pojasnjen v prvem izvedbenem primeru. Preko oboda 22 je možno namestiti še okrsno oblogo, ki ni prikazana na sliki.Figure 3 shows a second embodiment of an elastic heel suitable for any shoe. The heel is formed from the sole 20 and the inner plate 21, by which the heel is mounted on the heel inner part of the shoe not shown in the figure and the telescopic perimeter 22. In the interior, the elastic element 23, preferably a spring, is disposed between the sole 20 and the plate 21. which elastically intercepts the loads. The circumference 22, however, prevents the heel from bending outwards for the same purpose as previously explained in the first embodiment. It is also possible to fit a circumferential liner over the circumference 22, which is not shown.

Strokovnjaku s tega področja je očitno, da lahko izvede na osnovi opisanih izvedbenih primerov tudi drugačne izpeljanke zlasti v smislu industrijskega oblikovanja, ne da bi obšel bistvo izuma, kot je opredeljeno v priloženih patentnih zahtevkih.It will be apparent to one of ordinary skill in the art that, based on the described embodiments, he may also perform different derivatives, in particular in terms of industrial design, without circumventing the essence of the invention as defined in the appended claims.

Prav tako je razumljivo, da je obuvalo kakršnokoli ne glede na namen in obliko. Tudi razna ortopedska obuvala so primerna za sprejem ene ali druge izvedbe. Končno je možna izvedba same pete, zlasti po drugem izvedbenem primeru za prireditev pod peto mavčne obloge za nogo.It is also understandable that the shoe was of any kind whatever its purpose and shape. Various orthopedic shoes are also suitable for one or the other. Finally, it is possible to perform the heel itself, especially after the second embodiment for the event under the heel of the plasterboard leg.
