Description
Oppfinnelsen angår et opprullbart beskyttelsesgitter av den type som består av en flerhet av innbyrdes parallelle, på avstand fra hverandre liggende skinner, hver forsynt med to langsgående spor med sylindriske vegger for svingbar opptagelse av endene på en rekke mellom skinnene anordnede leddelementer. The invention relates to a roll-up protective grid of the type which consists of a plurality of mutually parallel, spaced apart rails, each provided with two longitudinal grooves with cylindrical walls for pivotable reception of the ends of a number of link elements arranged between the rails.
Beskyttelsesgitter av denne type er av kostnadshensyn laget av lettmetall og gir derfor ikke en fullgod beskyttelse, da de f.eks. kan klippes opp med en boltsaks eller et lignende verktøy. Protective grilles of this type are made of light metal for cost reasons and therefore do not provide adequate protection, as they e.g. can be cut open with bolt cutters or a similar tool.
Den type gitter som forekommer oftest, er derfor det stive gitter som er laget av stenger av herdet stål eller lignende ikke klippbart materiale. En ulempe ved disse, som man unngår ved anvendelse av rullbart gitter, er at de må løftes bort fra det butikkvindu eller den dør som gitteret skal beskytte, og dette er forholdsvis besværlig. En annen ulempe er at et,stivt gitter i sin helhet blir ødelagt hvis man ved innbrudd f.eks. anbringer en krok i gitteret og rykker det bort med et kjøretøy. The type of grating that occurs most often is therefore the rigid grating made from bars of hardened steel or similar non-cutable material. A disadvantage of these, which is avoided by using a rolling grid, is that they have to be lifted away from the shop window or the door that the grid is supposed to protect, and this is relatively cumbersome. Another disadvantage is that a rigid grid is destroyed in its entirety if, in the event of a break-in, e.g. places a hook in the grid and pulls it away with a vehicle.
Det viktigste formål med oppfinnelsen er å finne frem til et rullegitter som gir samme sikkerhet som et stivt gitter, og som enkelt kan repareres hvis det f.eks. rykkes løs fra butikkvinduet e.l. The most important purpose of the invention is to find a roller grille that provides the same safety as a rigid grille, and which can be easily repaired if, for example, is pulled loose from the shop window etc.
Denne hensikt oppnås med det gitter som er definert i patentkravene, og som nedenfor er beskrevet under henvisning til tegningen. Fig. 1 viser et parti av et gitter i henhold til oppfinnelsen sett mot gitterets plan. Fig. 2 viser den ene ende på en skinne med en bøyle i henhold til oppfinnelsen, idet bøylens ene arm er ført inn i et spor i skinnen, og This purpose is achieved with the grating which is defined in the patent claims, and which is described below with reference to the drawing. Fig. 1 shows a part of a grid according to the invention viewed against the plane of the grid. Fig. 2 shows one end of a rail with a hoop according to the invention, one arm of the hoop being led into a groove in the rail, and
fig. 3 viser Z-formede leddelementer. fig. 3 shows Z-shaped joint elements.
Et opprullbart gitter i henhold til oppfinnelsen omfatter en flerhet av skinner, f.eks. skinnene 1 og 2. Skinnene 1 og 2 er parallelle med hverandre og strekker seg horisontalt over det vindu, den dør e.l. som skal bekyttes. Antallet skinner tilpasses høyden på den åpning som skal beskyttes. Hver skinne 1, 2 er forsynt med to innbyrdes parallelle spor 3 og 4 langs de to motstående skinnekanter. Den indre vegg i sporene 3 og 4 er sylindrisk, som vist på fig. 2. Mellom de innbyrdes parallelle skinner 1 og 2 er anordnet en rekke leddelementer som i henhold til oppfinnelsen er utformet som bøyler med to parallelle armer, f.eks. armene 5 og 6 på bøylen 7 og armene 8 og 9 på bøylen 10. Armene 5 og 6 er forbundet med hverandre ved et mellomparti 11 og armene 8 og 9 ved et mellomparti 12. Hver bøyle er laget av et ikke klippbart materiale, hvormed her menes et materiale som ikke kan klippes av med håndverktøy, og består fortrinnsvis av en U-formig bøyet tråd eller stang med sylindrisk tverrsnittsflate. Det er viktig at armene 5, 6, 8, 9 er sylindriske for å kunne dreies i de åpne spor 3, 4 ved opprul-ling av gitteret. Mellompartiene 11, 12 kan imidlertid ha en hvilken som helst ønsket tverrsnittsform. For at den åpne sliss 13 i de respektive spor 3, 4 skal kunne gjøres så liten som mulig og sikkert holde fast bøylenes armer, som føres inn i de respektive spor fra den ene skinneende, kan de passende gjøres noe tykkere enn mellompartiene. Eventuelt kan bøylene lages av en jevntykk, sylindrisk tråd eller stang og armene deretter for-synes med en løs eller fast hylse for at man skal få den ønskede større diameter på armene. I det viste utførelseseksempel er, som vist på fig. 2, hver bøyle, f.eks. bøylen 14, bøyet slik at mellompartiet 15 ligger forskjøvet ut av det felles plan for de to innbyrdes parallelle armer. Dette skyldes at slissene, f.eks. slissen 13, er rettet skrått oppover i forhold til hverandre i den viste utførelsesform. For oppnåelse av den inn-ledningsvis nevnte sikkerhet mot oppklipping ligger bøylene slik innskutt i skinnene at enden på den respektive bøyle, f.eks. endene 16 og 17, ligger tett inntil eller i anlegg med mellompartiet, f.eks. mellompartiet 18, i en etterfølgende bøyle. Etterat bøylene er anbragt i denne stilling, låses de ytre bøyler fast på den respektive skinne ved hjelp av ikke viste organer. Det vil være klart at man ved forsøk på å klippe opp et gitter i henhold til oppfinnelsen alltid vil møte en herdet arm etter at skinnematerialet, som f.eks. er av lettmetall, er gjennomklippet, og at gitteret forblir intakt. Den mulighet som teoretisk foreligger til å klippe i området mellom en armende 17 og det inntil-liggende mellomparti 18, behøver ikke å innebære at skinnen kan klippes i stykker, ettersom det eneste man be-høver å gjøre er å ha en annen armelengde på de underliggende armer eller forskyve armene og dermed bøylene i forhold til hverandre slik at ethvert snitt gjennom en skinne alltid dekkes av en arm. A roll-up grid according to the invention comprises a plurality of rails, e.g. rails 1 and 2. Rails 1 and 2 are parallel to each other and extend horizontally over the window, the door etc. which must be protected. The number of rails is adapted to the height of the opening to be protected. Each rail 1, 2 is provided with two mutually parallel tracks 3 and 4 along the two opposite rail edges. The inner wall in the grooves 3 and 4 is cylindrical, as shown in fig. 2. Between the mutually parallel rails 1 and 2 are arranged a number of joint elements which, according to the invention, are designed as hoops with two parallel arms, e.g. the arms 5 and 6 of the hoop 7 and the arms 8 and 9 of the hoop 10. The arms 5 and 6 are connected to each other by an intermediate part 11 and the arms 8 and 9 by an intermediate part 12. Each hoop is made of a material that cannot be cut, with which here means a material that cannot be cut off with hand tools, and preferably consists of a U-shaped bent wire or rod with a cylindrical cross-sectional surface. It is important that the arms 5, 6, 8, 9 are cylindrical in order to be able to turn in the open slots 3, 4 when rolling up the grid. However, the intermediate parts 11, 12 can have any desired cross-sectional shape. In order for the open slot 13 in the respective tracks 3, 4 to be made as small as possible and to securely hold the arms of the hoops, which are inserted into the respective tracks from one rail end, they can suitably be made somewhat thicker than the intermediate parts. Optionally, the hoops can be made from a uniform thickness, cylindrical wire or rod and the arms are then provided with a loose or fixed sleeve in order to obtain the desired larger diameter of the arms. In the embodiment shown, as shown in fig. 2, each hoop, e.g. the hoop 14, bent so that the middle part 15 is displaced out of the common plane of the two mutually parallel arms. This is because the slits, e.g. the slot 13 is directed obliquely upwards in relation to each other in the embodiment shown. In order to achieve the initially mentioned security against clipping, the hoops are inserted into the rails in such a way that the end of the respective hoop, e.g. the ends 16 and 17, lie close to or in contact with the middle part, e.g. middle part 18, in a subsequent hoop. After the hoops have been placed in this position, the outer hoops are locked onto the respective rail by means of means not shown. It will be clear that when attempting to cut up a grid according to the invention, one will always encounter a hardened arm after the rail material, such as e.g. is made of light metal, is cut through, and that the grid remains intact. The possibility that theoretically exists to cut in the area between an arming 17 and the adjacent intermediate part 18 does not have to imply that the rail can be cut into pieces, as the only thing that needs to be done is to have a different arm length on the underlying arms or shift the arms and thus the braces in relation to each other so that any cut through a rail is always covered by an arm.
Et gitter i henhold til oppfinnelsen kan således ikke klippes opp med konvensjonelle klippeverktøy eller sages i stykker hvis materialet i bøylene velges riktig, og videre øde-legges ikke gitteret i sin helhet om det rives løs, idet de-formerte deler lettvint kan skiftes ut. A grid according to the invention cannot thus be cut open with conventional cutting tools or sawn into pieces if the material in the hoops is chosen correctly, and furthermore the grid is not destroyed in its entirety if it is torn loose, as deformed parts can be easily replaced.
I det tilfelle hvor armene har påtrædde hylser, som er fast eller løsbart forenet med armene, kan hylsene bestå av et hvilket som helst materiale, f.eks. plast. Fortrinnsvis lages de dog av stål. In the case where the arms have attached sleeves, which are firmly or releasably united with the arms, the sleeves can consist of any material, e.g. plastic. Preferably, however, they are made of steel.
Fig. 3 viser Z-formede leddelementer, dvs. at de to armer peker bort fra hverandre på en slik måte at bare en arm ligger i kontakt med eller tett inntil et bestemt tilgrensende leddelement. Mellompartiene hos de viste U- eller Z-formede bøylene behøver selvfølgelig ikke strekke seg vinkelrett på de med hverandre parallelle armer. Fig. 3 shows Z-shaped joint elements, i.e. that the two arms point away from each other in such a way that only one arm is in contact with or close to a certain adjacent joint element. The intermediate parts of the U- or Z-shaped hoops shown do not of course need to extend perpendicularly to the mutually parallel arms.
Videre er det mulig f.eks. å snu det høyre leddelement i fig. 3, slik at de to nedre armer er rettet mot hverandre og de to øvre fra hverandre. Risikoen for istykkerklipping av en skinne elimineres ved at armene i det ene spor i en skinne ligger tilstrekkelig forskjøvet i forhold til armene i skinnens annet spor til at man i hvert tverrsnitt gjennom skinnen vil treffe på en arm. Furthermore, it is possible e.g. to turn the right joint element in fig. 3, so that the two lower arms are directed towards each other and the two upper arms apart. The risk of a rail being cut to pieces is eliminated by the arms in one track in a rail being sufficiently offset in relation to the arms in the rail's other track that one will hit an arm in each cross-section through the rail.
