Description

DK 153687 BDK 153687 B

Opfindelsen angår et oprulleligt sikkerhedsgitter af den type, der består af et antal indbyrdes parallelle og i afstand fra hinanden anbragte skinner af -et'gennem-klippeligt materiale, der hver har to langsgående spor 5 med cylindriske vægge til drejelig optagelse på enderne af et antal mellem skinnerne anbragte led forbindelser.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a retractable safety grid of the type consisting of a plurality of parallel and spaced-apart rails of a cutable material, each having two longitudinal grooves 5 with cylindrical walls for pivotally accommodating the ends of a plurality of joints placed between the rails.

Sikkerhedsgitre af denne type fremstilles af hensyn til omkostningerne af letmetal og giver derfor ikke en fuldstændig sikring, idet de eksempelvis kan gennemskæres 10 ved hjælp af en boltsaks eller et lignende værktøj.Safety grids of this type are manufactured for the sake of light metal costs and therefore do not provide a complete fuse, as they can, for example, be cut 10 by means of a bolt cutter or a similar tool.

Den mest almindelige type sikkerhedsgitter er derfor det stive gitter, der består af stænger af hærdet stål eller et lignende ikke gennemklippeligt materiale. En mangel ved disse gitre, som man undgår ved anvendelse af oprul-15 lelige gitre, er, at man må løfte gitteret bort fra det butiksvindue eller den dør, der skal sikres, hvilket er forholdsvis besværligt. En anden mangel ved de stive gitre er, at de ødelægges som helhed, når der ved indbrud f. eks.. anbringes en krog i gitteret, og dette 20 rykkes bort ved hjælp af et køretøj.The most common type of safety lattice is therefore the rigid lattice, which consists of hardened steel rods or similar non-cut through material. One shortcoming of these grids, which is avoided by the use of retractable grids, is that the grid must be lifted away from the shop window or door to be secured, which is relatively cumbersome. Another disadvantage of the rigid grids is that they are destroyed as a whole when, for example, a hook is placed in the grille and this is removed by means of a vehicle.

Opfindelsen har derfor til formål at anvise et oprulleligt gitter af den anførte art, der giver samme sikring som et stift gitter, og som nemt kan repareres, hvis det f. eks. rykkes løs fra et butiksvindue eller lignen-25 de.It is therefore an object of the invention to provide a retractable grille of the kind specified which provides the same fuse as a rigid grille and which can be easily repaired if, for example, it is detached from a shop window or the like.

Dette formål opnås ved et gitter, der er udformet som anført i krav l's kendetegnende del, og som beskrives nærmere i det følgende under henvisning til tegningen, hvor 1 fig. 1 viser en del af et gitter ifølge opfindelsen, set mod gitterets plan,This object is achieved by a lattice formed as set forth in the characterizing part of claim 1, which is described in more detail below with reference to the drawing, in which: FIG. 1 shows a part of a grid according to the invention, viewed against the plane of the grid,

2 fig. 2 viser den ene ende af en skinne med en bøjle ifølge opfindelsen, og hvis ene gren er indført i et spor i skinnen, og fig. 3 viser to Z-formede ledforbindelser.2 FIG. 2 shows one end of a rail with a hanger according to the invention, and whose one branch is inserted into a groove in the rail; and FIG. 3 shows two Z-shaped joint connections.

5 Det viste oprullelige gitter ifølge opfindelsen omfat ter et antal skinner, f. eks. skinnerne 1 og 2, der er anbragt parallelt med hinanden og strækker sig vandret hen over det vindue, den dør eller lignende, der skal sikres. Antallet af skinner tilpasses til højden af 10 den åbning, der skal sikres. Hver skinne har to ind byrdes parallelle spor 3 og 4, der strækker sig langs hver sin af skinnens længdekanter. Sporenes inderside er cylindrisk som vist i fig. 2. De parallelle skinner er forbundet med hinanden gennem et antal bøjleformede 15 led, hver med to parallelle grene, jfr. grenene 5 og 6 på bøjlen 7 og grenene 8 og 9 på bøjlen 10. Grenene 5 og 6 er forbundet med hinanden gennem et mellemstykke 11, og grenene 8 og 9 er forbundet med hinanden gennem et mellemstykke 12. Bøjlerne er fremstillet af et ikke 20 gennemklippeligt materiale, hvorved her forstås et ma teriale, der ikke kan gennemklippes ved hjælp af et håndværktøj, og de består fortrinsvis af en i U-form ombukket tråd eller stang med cylindrisk tværsnitsflade. Det er væsentligt, at grenene 5, 6, 8, 9 er cy-25 lindriske, for at de skal kunne drejes i de åbne spor 3, 4 ved oprulning af gitteret. Mellemstykkerne 11, 12 kan derimod have enhver ønsket tværsnitsform. For at den åbne slids 13 i sporene 3, 4 kan være så lille som muligt, således at der opnås en sikker fatsholdel-30 se af bøjlernes grene, der føres ind i de pågældende spor fra skinnens ene ende, er grenene fortrinsvis noget tykkere end mellemstykkerne. Eventuelt kan bøjlerne dog være fremstillet af en cylindrisk tråd eller stang med konstant tykkelse, idet grenene da udstyres med et5 The shown retractable lattice according to the invention comprises a plurality of rails, for example the rails 1 and 2, which are arranged parallel to each other and extend horizontally over the window to which the door or the like is to be secured. The number of rails is adjusted to the height of 10 the opening to be secured. Each rail has two parallel grooves 3 and 4 extending along each of the longitudinal edges of the rail. The inside of the grooves is cylindrical as shown in FIG. 2. The parallel rails are connected to each other through a plurality of hanger-shaped joints, each with two parallel branches, cf. the branches 5 and 6 of the shackle 7 and the branches 8 and 9 of the shackle 10. The branches 5 and 6 are connected to each other through a spacer 11 and the branches 8 and 9 are connected to each other through a spacer 12. The shackles are made of a non 20 This is a material which cannot be cut through with the aid of a hand tool, and preferably consists of a U-shaped wire or rod with a cylindrical cross-sectional surface. It is essential that the branches 5, 6, 8, 9 are cylindrical in order to be able to rotate in the open grooves 3, 4 by rolling up the grating. The intermediate pieces 11, 12, on the other hand, can have any desired cross-sectional shape. In order for the open slot 13 in the grooves 3, 4 to be as small as possible, so as to obtain a secure hold of the brackets branches which are inserted into the respective grooves from one end of the rail, the branches are preferably somewhat thicker than between the pieces. Optionally, however, the braces may be made of a cylindrical wire or rod of constant thickness, the branches being then equipped with a

3 løst eller fast hylster, således at de får den ønskede større diameter. I det viste udførelseseksempel er, jfr. fig. 2, hver bøjle, f. eks. bøjlen 14 ombukket således, at mellemstykket 15 ligger forskudt ud fra det for bøj-5 lens to parallelle grenes fælles plan. Dette er betin get af, at eksempelvis slidserne 13 er rettet skråt opad bort fra hinanden i den viste udførelsesform. For at opnå den indledningsvis nævnte sikkerhed mod gennem-klipning er bøjlerne indskudt således i skinnerne, at 10 deres ender, f. eks. enderne 16 og 17 ligger tæt ved eller an mod mellemstykket, f. eks. mellemstykket 18 på den efterfølgende bøjle. Når bøjlerne er anbragt i denne stilling, fastlåses de yderste bøjler på skinnen ved hjælp af ikke viste organer. Det vil ses, at hvis 15 man forsøger at gennemklippe et gitter ifølge opfindel sen altid når skinnematerialet, f. eks. letmetal er gennemklippet, vil støde på en hærdet gren, og at gitteret forbliver intakt. Den teoretiske mulighed for, at klipningen sker i området mellem en grenende 17 og 20 det tilstødende mellemstykke 18 behøver ikke at inde bære, at skinnen kan gennemklippes, idet det eneste man behøver at gøre, er at have en anden grenlængde på de underliggende grene eller forskyde grenene og dermed bøjlerne i forhold til hinanden, således at hvert en-25 kelt snit gennem skinnen altid dækkes af en gren.3 loosened or fixed sleeve so that they get the desired larger diameter. In the illustrated embodiment, cf. FIG. 2, each hanger, e.g., the hanger 14 folded so that the intermediate piece 15 is offset from the common plane of the two parallel branches of the hanger 5. This is due to the fact that, for example, the slots 13 are directed obliquely upwardly away from each other in the embodiment shown. In order to obtain the initially mentioned cut-off safety, the shackles are inserted into the rails such that their ends, e.g., the ends 16 and 17, are close to or abut the middle piece, for example the middle piece 18 of the subsequent shackle. When the shackles are placed in this position, the outer shackles are locked to the rail by means not shown. It will be seen that if one tries to cut through a grid according to the invention always when the rail material, for example light metal is cut through, will encounter a hardened branch and that the grid remains intact. The theoretical possibility that the cutting occurs in the area between a branch 17 and 20 the adjacent intermediate piece 18 need not mean that the rail can be cut through, the only thing that needs to be done is to have a different branch length on the underlying branches or displacing the branches and thus the shackles relative to each other, so that every single cut through the rail is always covered by a branch.

Et gitter ifølge opfindelsen kan således ikke gennemklippes eller gennemskæres med et sædvanligt værktøj, såfremt bøjlernes materiale vælges rigtigt, og endvidere bliver gitteret ikke ødelagt i sin helhed, 30 hvis det rykkes løs, idet deformerede dele nemt kan udskiftes.Thus, a grating according to the invention cannot be cut or cut with a conventional tool, if the material of the braces is selected correctly, and furthermore, the grating is not destroyed in its entirety if it is pulled loose, as deformed parts can be easily replaced.

Såfremt grenene har påskudte hylstre, der er fast eller løst anbragt på grenene, kan hylstrene bestå af ethvert ønsket amteriale f. eks, plast. Fortrinsvis 35 består de dog af stål.If the branches have padded casings fixed or loosely affixed to the branches, the casings may consist of any desired amterial, for example, plastic. Preferably, however, they consist of steel.

Fig. 3 viser Z-formede ledforbindelser, dvs. at de to grene er rettede bort fra hinanden, således at kun en gren ligger an mod eller tæt ved det følgende led. Mellemstykket på de U- eller Z-formede led behøver ikke 5 at strække sig vinkelret på de indbyrdes parallelle grene.FIG. 3 shows Z-shaped linkage, i.e. that the two branches are directed away from each other, so that only one branch abuts or near the following link. The spacer of the U or Z-shaped joints need not extend perpendicular to the mutually parallel branches.

Der er endvidere muligt at vende det i fig. 3 højre led således, at de to nedre grene er rettede mod hinanden, og de to øvre grene er rettede bort fra hin-10 anden. Risiko for gennemklipning af grenene i det ene spor i en skinne elimineres ved, at grenene i det ene spor i skinnen ligger tilstrækkeligt forskudt i forhold til grenene i skinnens andet spor til, at-man i hvert tværsnit gennem skinnen vil støde på en gren.Furthermore, it is possible to reverse it in FIG. 3 right joints such that the two lower branches are facing each other and the two upper branches are directed away from the other. The risk of cutting through the branches in one track of a rail is eliminated by the fact that the branches in one track of the rail are sufficiently displaced relative to the branches in the other track of the rail that one cross section of the rail will encounter one branch.
