Description

Skotøy med formbibeholdende support. Footwear with shape-retaining support.

Denne oppfinnelse vedrorer en sko, hvori det er innarbeidet en forrabibeholdende support som består av en ved sprbytestbping fremstilt kunststoffdel med en stiv bindsåledel som strekker seg mellom haelpartiet og ballepartiet, samt en hælkappe som er fremstilt i ett stykke med bindsåledelen og er trukket frem til skogelenkområde. Supportens ytterside er overtrukket med skotbyets overdelmateriale. This invention relates to a shoe, in which a rabies-retaining support is incorporated, which consists of a plastic part produced by sprbystbping with a rigid binding sole part that extends between the heel part and the ball part, as well as a heel cap that is made in one piece with the binding sole part and is pulled forward to the shoe joint area . The outer side of the support is coated with Skotby's upper material.

I slikt skotby danner supporten, som kan fremstilles på en In such scotby forms the support, which can be produced on a

enkel måte, for eksempel ved sprbytning eller stbping, ikke bare den formbibeholdende skotbyhvelving, men den tjener også som formbibeholdende bærer for overlæret. Den tidligere nbdvendige forming av det bakre skaftparti på hælformemaskinen faller fblgelig bort. Derved oppnås det ikke bare en vesentlig forenkling og prissenkning av frem-stillingsprosessen, men det kan også for fremstilling av slikt skotby simple way, for example by changing springs or stitching, not only the shape-retaining scotby vault, but it also serves as a shape-retaining support for the upper leather. The previously necessary shaping of the rear shaft part on the heel shaping machine is obviously omitted. Thereby, not only is a significant simplification and price reduction of the production process achieved, but it is also possible for the production of such scotby

brukes tynnere og kvalitativt sett dårligere lær, uten at det er nddvendig med noen opparbeidelse av et mellomfor. Da supporten kan fremstilles ved sproytestbpning har man også forutsetninger for å utforme den med riktig lest, så at en sko utstyrt med en slik support har en mer korrekt passform enn i de tilfeller hvor overdelmaterialet i skotbyet, for eksempel overlæret, danner det formgiv-ende element. thinner and qualitatively inferior leather is used, without any preparation of an intermediate lining being necessary. As the support can be produced by spray testing, one also has the prerequisites to design it with the correct last, so that a shoe equipped with such a support has a more correct fit than in cases where the upper material of the shoe, for example the upper leather, forms the shaping end element.

Oppfinnelsen går ut fra den iakttakelse at man kan få vanskeligheter med hensyn på utformingen av supporten med riktig lest når supportens bindesåledel har en vesentlig stbrre tykkelse enn hælkappen. På grunn av den forskjellige hastighet hvormed supporten stiv-ner i de enkelte områder, kan supporten vri seg ved ujevn krymping. The invention is based on the observation that difficulties can arise with regard to the design of the support with the correct last when the binding sole part of the support has a significantly greater thickness than the heel cap. Due to the different speed with which the support hardens in the individual areas, the support can twist due to uneven shrinkage.

Disse vanskeligheter kan ifblge oppfinnelsen i det vesentlige unngåes ved at supporten påstbpes således på en under betingelsene ved sprbytestbpingen ikke eller bare lite krympende fullsåle som Så 1 ©d 6 S According to the invention, these difficulties can essentially be avoided by the support being thus applied to a non-shrinking or only slightly shrinking full sole under the conditions of the sprbytesting, such as So 1 ©d 6 S

strekker seg over hele skoens lengdest supporten griper under fullsålen, idet den del av fullsålen som lbper ut over supporten forover danner en bbyeelastisk såle. Ved siden av den krympningshemmende vir-kning tilfaller det således til fullsålen den ytterligere oppgave å utforme skobundingens forparti fleksibel, noe som er vesentlig for en uhindret avrulling av foten. Supporten og fullsålen danner en for-håndsfremstilt innbyggingsdel. Til fullsålen ifblge oppfinnelsen kan det anvendes materialer som svarer til eller ligger nær opptil de materialer som brukes til vanlige bindsåler. Ved disse materialer drei-er det seg om pressete fibermaterialer som er tilstrekkelig ettergiv-ende til ikke å hindre den naturlige avrullingsbevegelse for foten i ballepartiet og i alminnelighet også har en god opptakelsesevne for fotsvette. Slike pressete fibers tykker kan også lett klebes sammen med innerforet i skaftet. extends over the entire length of the shoe as far as the support grips under the full sole, as the part of the full sole that protrudes over the support forwards forms a bbyeelastic sole. In addition to the shrinkage-inhibiting effect, the full sole thus has the further task of making the front part of the shoe binding flexible, which is essential for unimpeded unrolling of the foot. The support and full sole form a pre-manufactured built-in part. For the full sole according to the invention, materials can be used that correspond to or are close to the materials used for normal bandage soles. These materials are pressed fiber materials that are sufficiently yielding not to hinder the natural rolling movement of the foot in the ball area and generally also have a good absorption capacity for foot sweat. Thicker such pressed fibers can also be easily glued together with the inner lining in the shaft.

Ved en foretrukket utfbrelsesform for oppfinnelsen er fullsålen i sin midtsone i området for hælkappen forsynt med en fortrinnsvis In a preferred embodiment of the invention, the full sole in its central zone in the area of the heel cap is preferably provided with a

langstrakt utformet utsparing som er utfylt med supportens kunststoff som er pålagt fullsålen som et sjikt på undersiden. Derved motvirker man ytterligere en forvridning av supporten når stbpestykket avkjbles. Et slikt utfbrelseseksempel er vist på tegningen, hvorav ytterligere trekk ved oppfinnelsen vil fremgå, og hvor: Fig. 1 viser et perspektlvriss av fullsålen som brukes ifblge oppfinnelsen, sett på dennes fotside. Fig. 2 viser et perspektlvriss av innbyggingsdelen som består av fullsålen og supporten. elongated recess that is filled with the support's plastic, which is applied to the full sole as a layer on the underside. Thereby, further distortion of the support is prevented when the support piece is disconnected. An example of such an embodiment is shown in the drawing, from which further features of the invention will be apparent, and where: Fig. 1 shows a perspective view of the full sole used according to the invention, seen from its foot side. Fig. 2 shows a perspective view of the built-in part which consists of the full sole and the support.

Fullsålen, som er betegnet med 1, består av et lett bbyelig, The full sole, which is denoted by 1, consists of an easily bendable,

men allikevel form-bibeholdende materiale, for eksempel et kunst-harpiksbasert fiberpresstykke, som lett kan klebes sammen med det ikke viste innerfor i skaftet. For å danne en utsparing 2 i hælområdet er en tunge 3 utstanset av fullsålen slik at denne fremdeles henger sammen med fullsålen ved sin mot sålespissen vendende ende. Fullsålen blir med en utforming som vist i fig. 1 anbragt i sprbyte-formen. Tungen 3 er altså avbbyet nedad, så at utsparingen 2 blott-legges slik at kunststoffet som danner supporten, kan flyte inn. but still shape-retaining material, for example a synthetic resin-based fiber press piece, which can easily be glued together with the not shown inner lining in the shaft. To form a recess 2 in the heel area, a tongue 3 is punched out of the full sole so that this still hangs together with the full sole at its end facing the tip of the sole. The sole has a design as shown in fig. 1 arranged in the sprbyte form. The tongue 3 is thus bent downwards, so that the recess 2 is exposed so that the plastic which forms the support can flow in.

På oversiden, det vil si fotsiden av tungen 3 er det festet en avstivende armering for sålegelenken i form av et fjærstålbånd h. On the upper side, i.e. the foot side of the tongue 3, a stiffening reinforcement for the sole joint in the form of a spring steel band h is attached.

Ved påstøpningen av supporten som dannes av en hælkappe 5°g en bindsåledel 6 på fullsålen 1 flyter kunststoffet over f jærstålbåndet M-, During the casting of the support formed by a heel cap 5 and a binding sole part 6 on the full sole 1, the plastic floats over the spring steel strip M-,

så at dette dekkes fullstendig av kunststoffmassen som danner supporten (se fig. 3 og 7). so that this is completely covered by the plastic mass that forms the support (see fig. 3 and 7).

Ved avbbyning av tungen 3 nedad kan denne under påstbping av supporten trykkes så fast an mot formveggen at dens underside ikke dekkes av kunststoffet. På undersiden av fullsålen er det fblgelig bare i området for kantstrimmelen som lbper ora utsparingen 2 påstøpt kunststoff fra supporten. When bending the tongue 3 downwards, this can be pressed so firmly against the mold wall during application of the support that its underside is not covered by the plastic. On the underside of the full sole, plastic from the support is probably only applied in the area of the edge strip that overlaps the recess 2.

For å holde fullsålens 1 kantstrimmel 1' som lbper rundt utsparingen fri for kunststoff på sin overside (fotside), blir fullsålen i dette område under påstbpingen av supporten trykket fast an mot formveggen. De stifter som er anbragt i flatene som begrenser støpeform-ens hulrom, og holder tungen 3 og kantstrimmelen 1' i den bnskete stilling under pås tapningen, etterlater i det ferdige stbpestykket de utsparinger 7 som vil sees av figurene J og 6. In order to keep the edge strip 1' of the full sole 1 which wraps around the recess free of plastic on its upper side (foot side), the full sole in this area is pressed firmly against the mold wall during the application of the support. The pins which are placed in the surfaces which limit the cavity of the mould, and which hold the tongue 3 and the edge strip 1' in the desired position during the taping, leave in the finished piece the recesses 7 which will be seen in figures J and 6.

Består fullsålen av et materiale som lett kan klebes sammen med skotbyets innerf&r, frembyr den av supportens kunststoff ikke dekkete overside på kantstrimmelen 1<*>en gunstig klebeplate for forbindelse med innerforet. If the full sole consists of a material that can easily be glued together with the inner lining of the boot, the upper side of the edge strip 1<*> not covered by the support's plastic provides a favorable adhesive plate for connection with the inner lining.

Ved den utsparing 2 som ifblge oppfinnelsen er anbragt i den bakre del av fullsålen 1, får man den mulighet at supportens kunststoff kan flyte over fullsålens fotside i gelenken. Det sjikt 8 som derved dannes, ender i det midtre såleområde 1 liten avstand fra den linje i fullsålen som den akse ligger på, hvorom sålen i ldpet av den naturlige avrullingsbevegelse for foten avboyes. Derved unngås et brudd på sålen i avrullingssonen. Kunststoffbelegget på fullsålens overside i gelenkområdet har den fordel at det véd kunststoffets krymping ved avkjoling danner seg en skålformet fordypning, noe som er gunstig for tilpassing av sålen til fotformen. Hvis kunststoffbelegget i gelenken ikke hadde vært anbragt på oversiden men på fullsålens underside, ville dette ha medfort en utbuling av fullsålen opp-ad og dermed en avvikelse fra fotformen. With the recess 2 which, according to the invention, is located in the rear part of the full sole 1, you get the possibility that the plastic of the support can flow over the foot side of the full sole in the joint. The layer 8 that is thereby formed ends in the middle sole area 1 a short distance from the line in the full sole on which the axis lies, around which the sole is deflected due to the natural rolling motion of the foot. This prevents a break in the sole in the roll-off zone. The plastic coating on the upper side of the full sole in the joint area has the advantage that due to the shrinkage of the plastic on cooling, a bowl-shaped depression forms, which is beneficial for adapting the sole to the shape of the foot. If the plastic coating in the joint had not been placed on the upper side but on the underside of the full sole, this would have resulted in a bulge of the full sole upwards and thus a deviation from the shape of the foot.

Som det vil fremgå av figurene 2 og 5»danner kunststoffbelegget 8' ved den ende som vender mot sålespissen en konkav bue 9. Kantsonene på kunststoffbelegget 8 nærmer seg derved sålens boyesone og bidrar derved til forbedring av fotens stotte, fordi det vesentlig oker sålens motstand mot avknekking sideveis. As will be seen from figures 2 and 5, the plastic coating 8' forms a concave arc 9 at the end facing the sole tip. The edge zones of the plastic coating 8 thereby approach the sole's bow zone and thereby contribute to improving the foot's support, because it significantly increases the sole's resistance against buckling laterally.

Sålens 1 balleområde som ligger foran buen 9 er, slik fig. h klargjor, likeledes utformet skålformet for å tilpasses etter utformingen av fotsålen eller lestbunnen. Denne utforming utfores fortrinnsvis i en arbeidsgang sammen med påstopingen av supporten på fullsålen 1, hvorved det trykk som kommer til anvendelse ved stbpeprosessen samt varmen nyttiggjbres for tilforming av sålen 1. The ball area of the sole 1 which lies in front of the arch 9 is, as fig. h klargjor, likewise designed cup-shaped to be adapted to the design of the sole of the foot or the bottom of the last. This design is preferably carried out in one work step together with the stuffing of the support on the full sole 1, whereby the pressure that comes into use during the stamping process as well as the heat is used to shape the sole 1.

For at det under påstbpingen av supporten kan dannes en fra undersiden av tungen 3 fremstikkende ansats 10 for å påsette en - ikke vist - hæl, er det i tungen 3 anordnet en utsparing 11, hvor gjennom kunststoffet kan flyte og inn i en utsparing som er anordnet i sprbyte-formen for å danne ansatsen 10. Denne ansats 10 er fortrinnsvis utformet kantet, så at hælen ved påsetting på ansatsen samtidig sentre-res . In order that during the application of the support a projection 10 protruding from the underside of the tongue 3 can be formed to attach a - not shown - heel, a recess 11 is arranged in the tongue 3, through which the plastic can flow and into a recess which is arranged in the sprbyte shape to form the shoulder 10. This shoulder 10 is preferably designed angular, so that the heel is simultaneously centered when attached to the shoulder.

Utsparingen 11 i tungen omgis av utsparingen 12 i fjærstålbåndet W, hvorved kunststoffet får adkomst til utsparingen 11. The recess 11 in the tongue is surrounded by the recess 12 in the spring steel band W, whereby the plastic gets access to the recess 11.

Supporten ifblge oppfinnelsen består fortrinnsvis av hbytrykks-polyetylen, som har de gunstige fysikalske egenskaper for supporten under bruk. The support according to the invention preferably consists of high-pressure polyethylene, which has the favorable physical properties for the support during use.

Fortrinnsvis blir kunststoffet innsprbyfet i formen på et sted som ligger i området av den bakre ende av fullsålen 1, fortrinnsvis på et sted som ligger foran sålens toppunkt. Dette vil medfbre en slik orientering av molekylkjedene i supportens lengderetning at kunststoffets krymping gjor seg lite merkbar i det ferdige stbpestyk- Preferably, the plastic is injected into the mold at a location located in the area of the rear end of the full sole 1, preferably at a location located in front of the top of the sole. This will result in such an orientation of the molecular chains in the longitudinal direction of the support that the shrinkage of the plastic is hardly noticeable in the finished block piece.

Ved anvendelse av den innbyggingsdel som består av fullsålen When using the built-in part that consists of the full sole

1 og supporten 5i 6, får man fdlgelig en endring i forhold til den vanlige fremstilling av skoskaftet, fordi overdelmaterialet nu forst trekkes over i hælområdet og skotbyet dermed bearbeides bakfra og forover og ikke mere som tidligere forfra og bakover. 1 and the support 5 in 6, you get a change in relation to the usual production of the shoe shaft, because the upper material is now first pulled over in the heel area and the shoe base is thus processed from back to front and no longer as before from front to back.
