Description
Oppfinnelsen angår et U-formet lukkeklammer som består av to ben og et steg som forbinder benene, som består av et materialstykke med likeformet tverrsnittsform og beregnet for lukking av muleaktig sammensnurpede emballasjehylstre ved blivende deformering av lukkeklammeret ved hjelp av et lukkeverktøy. The invention relates to a U-shaped closure clip which consists of two legs and a step connecting the legs, which consists of a piece of material with a uniform cross-sectional shape and intended for closing mule-like shriveled packaging cases by permanent deformation of the closure clip using a closing tool.
Fra US-patent nr. 3.463.156 er det kjent et lukkeklammer som er beregnet til underbinding av blodårer ved operasjoner ved hjelp av et tangformet lukkeverktøy. Dette klammer har en vesentlig C-formet utførelse og blir innsatt mellom tilnærmet parallelle ben i det åpne verktøyet og blir ført med dette til lukkestedet og der trykket sammen om den blodåren som skal underbindes. Derved blir det dannet et flatt lukkested som er avgrenset av de parallelt til hverandre beliggende ben av lukkeklammeret, idet enden av det ene benet ved hjelp av en tilbakebøying overlapper enden av det andre benet. From US patent no. 3,463,156, a closing clamp is known which is intended for underligating blood vessels during operations using a pincer-shaped closing tool. This clamp has a substantially C-shaped design and is inserted between approximately parallel legs in the open tool and is led with this to the closure site and there pressed together around the vein to be ligated. Thereby, a flat closing point is formed which is delimited by the parallel legs of the closing clip, with the end of one leg overlapping the end of the other leg by means of a backward bend.
Et slikt lukkekammer er bare egnet for relativt små lukkeoppgaver, der kraftbehovet for en varig deformering uten vanskelighet kan frembringes. Ved lukking av emballasjehylsteret må det benyttes vesentlig sterkere lukkeklammere, slik at det også er nødvendig med større lukkekraft, noe som er med å bestemme utformingen av lukke-verktøyet og utformingen av selve lukkeklammeret. Det har vist seg at ved flatt sammentrykte klammerben er det vanskelig å få en tett og varig lukking, da materialtverr-snitt med hensyn til kraftbehovet ikke kan økes i ønsket grad, slik at de rette og parallelt beliggende klammerbenene ikke greier å motstå åpningstrykket etter lukkingen. Such a closing chamber is only suitable for relatively small closing tasks, where the power requirement for permanent deformation can be produced without difficulty. When closing the packaging sleeve, significantly stronger closing staples must be used, so that greater closing force is also required, which helps determine the design of the closing tool and the design of the closing staple itself. It has been shown that with clamp legs compressed flat it is difficult to get a tight and lasting closure, as the material cross-section with respect to the power requirement cannot be increased to the desired degree, so that the straight and parallel clamp legs are unable to withstand the opening pressure after closing .
Fra US-patent nr. 3.673.640 er det videre kjent It is further known from US patent no. 3,673,640
et lukkeklammer som kan benyttes om igjen og som består av et flatt materialstykke, der et materialsteg er stanset ut på tre sider og bøyd oppover. a closing clip that can be used again and which consists of a flat piece of material, where a material step is punched out on three sides and bent upwards.
Dette midtsteget danner i realiteten et halvt lukkeklammer mens den øvrige del av materialstykket danner den andre halvdelen. Den fremre frie enden av midtsteget er utformet krokformet og beregnet til inngrep i den utstansede åpningen når lukkeklammeret blir lukket omkring lukkestedet. This middle step in reality forms half a clasp, while the other part of the piece of material forms the other half. The front free end of the middle step is designed hook-shaped and intended for engagement in the punched-out opening when the closing clip is closed around the closing point.
Også dette klammeret er bare brukbart for et be-grenset bruksområde da det flate materialstykket, og særlig det utstansede midtsteget bare kan pålegges forholdsvis små lukkekrefter. Klammeret skal således lukkes for hånd, altså uten verktøy og kan derfor ikke oppvise noe kraftig material-tverrsnitt for at det skal kunne lukkes med liten kraft. Endelig kan klammeret benyttes om igjen, dvs. det må under bruk ikke undergå noen varig deformering. This clamp is also only usable for a limited area of use as the flat piece of material, and in particular the punched-out middle step, can only be subjected to relatively small closing forces. The clamp must therefore be closed by hand, i.e. without tools and therefore cannot have a strong material cross-section so that it can be closed with little force. Finally, the clamp can be used again, i.e. it must not undergo any permanent deformation during use.
Hensikten med foreliggende oppfinnelse er å frem-skaffe et U-formet lukkeklammer som ved hjelp av et lukke-verktøy og ved bruk av forholdsvis små lukkekrefter kan bøyes tilnærmet sirkelformet omkring den muleformet sammenrynkede halsen av et emballasjehylster eller lignende. The purpose of the present invention is to provide a U-shaped closing clip which, with the help of a closing tool and the use of relatively small closing forces, can be bent in an approximately circular shape around the mule-shaped shrunken neck of a packaging sleeve or the like.
Dette oppnås ifølge oppfinnelsen ved at lukke-klammerets ben forløper bueformet i samme retning for å kunne bevege disse langs en sirkelformet føringsvei i lukke-verktøyet, slik at benene ligger i tilnærmet konsentrisk forløpende sirkelbuer og ved enden av føringsveien ved sine ender som avgrenser klammeråpningen løper mot en stasjonær matrise på lukkeverktøyet, som videre bøyer det ene ben i samme retning som det på forhånd er bøyd i og bøyer det andre benet i retningen mot bøyen på benet. According to the invention, this is achieved by the legs of the closing clip extending arcuately in the same direction in order to be able to move them along a circular guide path in the closing tool, so that the legs lie in approximately concentric circular arcs and at the end of the guide path at their ends which delimit the clip opening run against a stationary die on the closing tool, which further bends one leg in the same direction as it was previously bent and bends the other leg in the direction against the bend of the leg.
På denne måte oppnås at den permanente deformering av lukkeklammeret ikke skjer på begge benene samtidig i lukkeverktøyet, slik at den lukkekraft som står til rådig-het blir utnyttet og man unngår derved momentant oppstående deformeringsmotstand. In this way, it is achieved that the permanent deformation of the closing clip does not occur on both legs at the same time in the closing tool, so that the closing force that is available is utilized and momentarily arising deformation resistance is thereby avoided.
Hensiktemssig blir benendene som begrenser klammeråpningen bøyd lett mot hverandre for å unngå fare for stuking når benene treffer matrisen, og for å lette inn-ledningen av deformeringen. Purposefully, the leg ends which limit the clamp opening are bent slightly towards each other to avoid the risk of sprains when the legs hit the matrix, and to facilitate the introduction of the deformation.
Videre er det fordelaktig å utforme benene ulike lange, idet det sterkest krummede benet er kortest. Også dette trekket tjener til å holde den nødvendige' kraften så lav som mulig ved lukkingen og å danne et likeformet,omtrent sirkelformet lukke som utøver like stort lukkepress på alle sider og derved tillater en optimal materialut-nyttelse. Et ytterligere trekk ved oppfinnelsen går ut på at steget som forbinder benene tilnærmet danner en halvsirkel, dvs. omtrent oppviser den etter lukkingen tilsiktede formen. Dermed spares formingsarbeidet og samtidig skaffes et formgivende anlegg for det muleåktig sammenrynkede lukkestedet på emballasjehylsteret, slik at den optimalt anerkjente, sirkelformede lukking blir dannet. Furthermore, it is advantageous to design the legs of different lengths, as the most curved leg is the shortest. This feature also serves to keep the necessary force as low as possible when closing and to form a uniform, roughly circular closure that exerts equal closing pressure on all sides and thereby allows optimal material utilization. A further feature of the invention is that the step which connects the legs approximately forms a semicircle, i.e. roughly exhibits the intended shape after closure. In this way, the shaping work is saved and at the same time a shaping device is provided for the mule-like wrinkled closure on the packaging sleeve, so that the optimally recognized, circular closure is formed.
Klammeret ifølge oppfinnelsen har ytterligere den fordel at det er velegnet for lukkeinnretninger som har en sirkelbueformet klammerføringsvei. Et slikt klammer egner seg særlig godt til tangformede håndverktøy med en slik klammerførihgsbane, da de er spesielt godt egnet for å oppnå en sikker og lett gjennomføring av rynkingen og lukkingen for hånd. The staple according to the invention has the further advantage that it is suitable for closing devices which have a circular arc-shaped staple guide path. Such a clamp is particularly well suited to pincer-shaped hand tools with such a clamp guide path, as they are particularly well suited for achieving safe and easy completion of the creasing and closing by hand.
Klammeret ifølge oppfinnelsen har videre den fordel at det mot lukkeretningen bøyde, indre ben oppviser en kraftigere lukkekraft enn et rett eller i lukkeretningen bøyd ben. Ved at det indre benet oppviser en større holde-kraft mot den statiske tilbakeføringskraften, dvs., den lukkede mulens forsøk på å åpne seg, er det mulig ved hjelp av samme lukkekraft å oppnå et mindre tverrsnitt på klammeret, eller ved samme tverrsnitt å oppnå en fastere og sikrere lukking. The clamp according to the invention also has the advantage that the inner leg bent towards the closing direction exhibits a stronger closing force than a straight leg or a leg bent in the closing direction. As the inner leg exhibits a greater holding force against the static return force, i.e., the closed mule's attempt to open, it is possible with the same closing force to achieve a smaller cross-section of the clamp, or with the same cross-section to achieve a firmer and more secure closure.
Det kan benyttes tråder med forskjellige profiler til klammeret ifølge oppfinnelsen. Threads with different profiles can be used for the clip according to the invention.
Oppfinnelsen skal i det følgende forklares nærmere med henvisning til tegningen, der The invention will be explained in more detail below with reference to the drawing, where
fig. 1 viser klammeret i åpen tilstand, fig. 1 shows the clamp in the open state,
fig. 2 og 3 viser klammeret i lukket tilstand, og fig. 2 and 3 show the clamp in a closed state, and
fig. 4 viser bruk av klammeret i en lukkeinnretning med sirkelbueformet klammerføringsvei. fig. 4 shows the use of the staple in a closing device with a circular arc-shaped staple guide path.
Det U-formede klammeret oppviser ben 1,2 samt et forbindelsessteg 3. Benene 1,2 er bøyd i samme retning. The U-shaped clamp has legs 1,2 and a connecting step 3. The legs 1,2 are bent in the same direction.
De ligger på sirkelbuer med radiene R, og R_ med felles senter 4. Det således sterkest krummede indre ben' 2 er kortere enn det ytre benet 1. Benendene 5,6 er bøyd mot hverandre for å lette lukkingen av klammeret. Steget 3 som forbinder benene 1,2 danner tilnærmet en halvsirkel, slik at det kan tilpasse seg optimalt til mulen 10. They lie on circular arcs with radii R, and R_ with a common center 4. The thus most strongly curved inner leg' 2 is shorter than the outer leg 1. The leg ends 5,6 are bent towards each other to facilitate the closing of the clamp. The step 3 that connects the legs 1,2 forms approximately a semicircle, so that it can adapt optimally to the mule 10.
Fig. 2 og. 3 viser klammerene i lukket tilstand, idet klammerbenene er ført forbi hverandre. De har lagt seg mer eller mindre an mot muleomkretsen alt etter tykkelsen på mulen. Fig. 2 and. 3 shows the clamps in a closed state, the clamp legs having been guided past each other. They have applied themselves more or less to the mule circumference, depending on the thickness of the mule.
I fig. 4 er vist et lukkeverktøy med sirkelbueformet forløpende klammerføringsvei (se pilen), til hvilket verktøy klammerene kan benyttes. Klammere med benene 1,2 blir grepet av gapet 7 i en stempelplate 8. Ved rynkingen og lukkingen fører stempelplaten 8 ved dreining omkring senteret 9 klammeret langs en sirkelbueformet føringsvei først til omgrep om mulen 10 på et emballasjehylster. Klammeret treffer deretter med sine ulike lange ben 1,2 med innoverbøyde benender 5,6 mot matrisen 11, hvorved benene 1,2 legger seg ved siden av hverandre og omkring emballasjemulen. In fig. 4 shows a closing tool with a circular arc-shaped continuous staple guide path (see arrow), for which tool the staples can be used. Staples with legs 1,2 are gripped by the gap 7 in a piston plate 8. During the creasing and closing, the piston plate 8, by turning around the center 9, leads the staple along a circular arc-shaped guide path first to grip the mule 10 on a packaging sleeve. The clamp then hits with its various long legs 1,2 with inwardly bent leg ends 5,6 against the matrix 11, whereby the legs 1,2 lie next to each other and around the packaging mold.
